Bad copy of Philips electric toothbrush from Azdent - first autopsy and resuscitation. We pump/reanimate the Braun electric toothbrush (Oral-b) The Oral bi electric toothbrush does not work

Rechargeable toothbrushes have been clinically proven to remove plaque better than regular toothbrushes. Although they are relatively expensive, with proper care these brushes will last at least 5 years. The brush heads are easy to change, allowing the whole family to share one power handle and still have their own toothbrush.

How does it work

The cleaning action is provided by the orbital movement of the brush head attached to the end of the head holder barrel. The hollow barrel includes a miniature gearbox in its design and is placed on the drive spindle in the handle. The handle, which is made in the form of a non-separable unit, contains an electric motor, an electronic control unit and a rechargeable battery. Some handles have an external switch slider. In other models, the switch button is covered with a flexible rubber-like cover.

  3. Closed switch
  4. Charger

Each brush is equipped with a charger on which the brush is installed to recharge the battery. The charger is also an isolated monobloc design - charging is done inductively and there are no metal contacts electrically connecting the handle and the charger. Therefore, the rechargeable toothbrush can be used completely safely in the bathroom, and the device is equipped with a two-pole plug for electric shavers. If there is no outlet for an electric razor, then the charger can be plugged into any outlet in the house through the appropriate adapter. The charger body may have a compartment for replaceable brush heads.

Battery charge

When charging your new toothbrush for the first time, place it on the charger and the indicator light will illuminate to indicate that it is charging. Leave it to charge for the amount of time indicated in the instructions (usually 16 hours), then remove the brush from the charger and let it run until it runs out of charge.

Rice. 2 Charging an electric toothbrush

Place the brush back on the charger and charge for 16 hours or as directed by the manufacturer. To keep the battery in good working order, it is recommended to repeat this procedure approximately every six months. For optimal use, it is best to keep the brush on the charger in constant charging mode - the battery will not take “too much” charge.

Reciprocating motion

To increase the cleaning effect, the latest models have added a reciprocating component to the orbital movement of the brush head.

Two minute warning

Cordless toothbrushes have a built-in timer that, after 2 minutes, causes the brush to work intermittently for several seconds - this is a signal that the minimum recommended duration of brushing has passed. The motor will then operate normally again so that cleaning can continue. For some models, you can select the speed of movement to avoid discomfort with sensitive teeth and gums.

CLEANING THE CORDLESS TOOTHBRUSH

After brushing your teeth, rinse the brush under running water while it is on. Rinse the brush head and holder barrel with water and dry with a paper towel or napkin.

About once a week, remove the brush head and rinse it all the way through the tail to clean the inside. Wipe the drive shaft and handle with a damp cloth. If you have hard water, do this more often to avoid mineral deposits.

Rice. 3 Cleaning an electric toothbrush.

If black plaque begins to accumulate on your brush, do not use toothpaste with a whitening agent. This generally harmless discoloration is caused by bleach deposits in the crevices of your toothbrush.

The deposit may not be noticeable under the slide switch of older models. To clean this area, move the slider back until it disengages and scrub off the residue with a nail brush under running water. When all parts are clean, you need to press the switch and move it forward so that it falls into place. Be careful not to turn the engine backwards.

From time to time, unplug the charger from the outlet and wipe it with a damp cloth. If the device has a unit with a compartment for storing brush heads, then remove it and rinse it under running water. Dry the unit thoroughly before reinstalling it.

Spontaneous turning on of the toothbrush

Water got inside

A crack in the body or a torn rubber band covering the switch button may allow water to enter the brush. This defect cannot be repaired.

Green indicator does not work

When the brush is placed on the charger, the green indicator light should light up. Make sure the charger plug is plugged into the outlet and check the following:

No power supply

If other devices in the same circuit have stopped working, check the panel: there is a blown fuse or a tripped circuit breaker or RCD.

The presence or absence of voltage can be shown by a non-contact tester if you touch the base protrusion on which the toothbrush is placed.

Rice. 4 Bring the non-contact tester to the base protrusion

If it looks like the charger isn't working, then you'll almost certainly have to buy a whole new set.

BRUSH DOESN'T WORK

Water gets inside

If the brush is dropped, its body may burst and water will get inside.

Putting too much force on the spindle when brushing your teeth can damage the seal and cause it to leak.

The rubber coating on the power button may tear and allow water to enter.

If any of these types of damage occurs, the rechargeable toothbrush is likely beyond repair.

Battery won't charge

The battery being charged may be damaged. First test the charger using a non-contact tester (see above). If there is voltage, ask the service center if it is possible to replace the toothbrush itself.

Faulty charger

See above..

Time and pressure indicators

Brushes are made with colored bristles, which should fade after a certain time, and this is a signal that it is time to change the head. Dentists recommend in any case changing the brush head after three months of use and even earlier if the bristles are bent or deformed.

Rice. 5

Bent bristles are a sure sign of excessive pressure on the brush; Only light guiding pressure is required. The latest models are made taking this circumstance into account. This could be a spring-loaded head that reacts to excessive force, or intermittent operation, etc.

THE MAIN THING IS SAFETY

Batteries should not be disposed of with household waste. If they fail, return them to the manufacturer's service center, where they will be safely disposed of.

Good luck with the renovation!

All the best, writeto © 2009

Hi all! In today's review we will look at another electric toothbrush, the prototype of which I wrote a review about (). This one also features inductive charging and a slightly modified design. Anyone interested in this topic, please follow the cut! (For the impatient, I do not recommend purchasing)

It so happens that I am not writing the first review of products from this seller. I don’t get toothbrushes for free (for those who think they’re bribing me), but by paying part of the costs. Therefore, there is no point in hiding shortcomings and praising a bad product. Let's move on from the lyrics to the review!

The toothbrush does not have a name, although there is some information and designations on the packaging. I don't see the point in looking at her.


But at the end there are color options: pink, green and 2 blue options.


The kit also includes an instruction manual for those who cannot figure out the only button. Information is available in English and Chinese.




The package itself is as follows:
  • electric brush
  • induction charging
  • 3 nozzles


Let's start with the most interesting thing, namely the difference between a regular brush and this one - induction charging.


To do this, let's disassemble the charger, for this we only need a knife, since the Chinese did not even bother to solder or glue the connection of the 2 parts.


After removing the cover we see the microcircuit board and the coil with the core. I’ll say right away that it was done clumsily, the 2 wires going to the coil can easily break if you open the charger. So be careful!


The microcircuit with elements is presented below.


We also immediately replace the Chinese plug with a European one.


I was never able to disassemble the handle of the toothbrush, even though the knife helped me. But it seems to me that the insides of these brushes should be the same, the only difference is in the feeding element and the method of receiving energy. And since the second one was sorted out without any problems, we will analyze it. The engine has no designations, the only thing is that it is 2.4 volts.


The previous brush had 2 AA batteries, which drove the motor shaft, which in turn rotated the nozzle. To seal the motor from water and toothpaste, there is a rubber gasket that quickly becomes clogged, thereby reducing the rotation speed.


The power button opens the positive contact




The rotation speed can be seen below


After what we saw, we can conclude that most likely the quality of the charger in the handle itself is not much different for the better compared to the mains one. The motor will be the same, and the batteries will be 2 AAA batteries. (the price of an electric motor in Russia starts from 50 rubles per piece, with some simple calculations you can understand the degree of markup)

Let's move on to comparing brush attachments. We are interested in whether they are interchangeable and whether the Chinese have somehow changed the design.


The main difference is that the new model has reduced the length of the nozzle and increased the area of ​​the fibers


The rotation device has also changed; if previously the moving part of the body rotated, then in the new model they made an external disk. After long-term use of the old model, sticking and deformation of the rotating element occurred. I hope that by changing the design, the manufacturer has avoided this problem.


Changes were made to both the drain hole on the back of the nozzle and the method of fastening in the handle. Now the nozzles do not fit together.


Fortunately, visual differences have been preserved, in the form of multi-colored rubber bands. I believe that when more than 2 people use a brush in the house, this is an important necessity!


To understand how the fibers move to the nozzles, I created an animation; to put it in Russian, the fibers move back and forth at high speed.

Let's move directly to the handle of the toothbrush. It was made monolithically, apparently after the battery and receiver were assembled inside, the lower part was soldered.


The controls are made in the form of a single on/off key. To indicate the charge, there is a peephole with an LED inside (it does not change color depending on the state of charge, this indicates that the current is constantly flowing)




On the bottom there is a recess for charging; it fits tightly and does not play.


The crosspiece mounted on the electric motor shaft is also different from its counterpart. Basic collection of toothpaste.


The dimensions have changed for the better, the new toothbrush has reduced its size. At the same time, leaving rubberized inserts for easy grip. But the problems of the previous model also remained, namely rubber stamping without subsequent processing. The hole for water drainage from the handle has been enlarged.






The dimensions are smaller than the old model, making the grip even more comfortable. But still remains large compared to my previous brushes: and


In order to understand how loud the new toothbrush has become, compare using an application on a smartphone.


Noise level in the room


New toothbrush, fairly quiet operation.


The old one turned out to be even quieter after I took it apart and cleaned it of toothpaste.


What I was talking about. With prolonged use, the nozzle becomes deformed and makes unpleasant sounds.

As a conclusion, we can say the following: the price for which they offer to buy this toothbrush is incredibly high! Paying more than $4 for it is blasphemy, but by adding a small amount you can buy something that I have previously reviewed and fully deserved the right to purchase!
Links to previous models were also in the text, but I will duplicate them here:
Sonic brush review
Review of oral-B analogue

The product was provided for writing a review by the store. The review was published in accordance with clause 18 of the Site Rules.

Oral health is impossible without quality care, and a toothbrush is the first assistant in this. The quality of cleaning with its help depends on the type of paste and the correct execution of manipulations. On the advice of dentists, more and more people are switching to electric toothbrushes. They clean plaque better and thoroughly treat the oral cavity in hard-to-reach places.

Types of Braun Oral-B electric toothbrushes

Testing of Oral B Braun electric toothbrushes has shown their effectiveness in combating the formation of tartar, soft plaque, and the spread of caries. Special attachments help to cope with changes in the shade of enamel from tobacco, coffee, tea, and other stains. Polishing attachments eliminate the unpleasant taste and feeling of “dirty” teeth.

Such devices are not suitable for everyone, so when choosing, it is important to get advice from a dentist. A good doctor will not recommend electric brushes to patients with sensitive enamel, wedge-shaped defects in teeth, bleeding gums, or artificial teeth. The presence of a pacemaker or a tumor in the oral cavity is also a contraindication.

Electric brushes require a power source - batteries or rechargeable batteries. The type of battery determines the power and rotation of the head and the ability to take the device on a trip. Experts advise choosing a device based on the desired functionality.

Mechanical

The cleaning element in mechanical models is a round head with bristles. Depending on the capabilities of the brush, it is capable of rotating in a circular pulsating or reciprocating mode, performing from 5,000 to 30,000 combined movements per minute.

The negative aspects of Oral B Professional mechanical devices are their low power compared to sonic and ultrasonic devices, and the heads move in only one direction. This reduces the capabilities of the device, but does not become a barrier for people who do not need special dental care.


Sonic and ultrasonic

Oral b Braun sound models contain a high-frequency generator of sound vibration waves. The head vibrates at up to 18,000 movements per minute. At the same time, the oral cavity is well cleaned of plaque, and sound vibrations weaken the connection of bacteria with the enamel surface. When cleaning with such models, no special skills are required, and even children can master the process.

In ultrasonic devices, cleansing is based on the active influence of ultrasound on bacteria that are present on the gums and teeth. High frequency waves penetrate 4 mm. deep into the bristles, allowing you to clean the interdental space, gingival grooves, and other hard-to-reach places. Models of ultrasonic brushes remove soft pigment plaque. During operation, the device increases the temperature of surrounding tissues by 1 degree. This promotes active penetration of the healing components of the paste.

No brush can cope with tartar and hard plaque. To remove them, special techniques are used in the dental hygienist’s office.

Recharging the device

The battery device is supplied with a charger with a two-way plug for recharging. It is plugged into a socket for electric shavers, or using an adapter into a regular socket. Charging is carried out inductively, without metal elements connecting the handle and the device. Thanks to this, the charging base can be placed wherever it is convenient, including in the bathroom.

The best option for owners of electric brushes is to keep them charged all the time between uses. When first used, the manufacturer recommends fully charging the battery (within 12-16 hours), and then completely discharging it. Then fully charge the battery again and keep it in working condition. This procedure will extend the life of the battery. It is recommended to repeat it once every six months.

When do you need to change batteries?

When it is not possible to connect to a power supply, a full charge of the electric brush should be enough for a week. A decrease in the functionality of the battery indicates that it is exhausting its resource and will soon need to purchase a new one. After how many months is the first replacement needed? Typically, at least 2 years pass from the start of operation to the first battery change. Signs your Oral B battery needs to be replaced:

  • The charge is enough for 1-2 teeth brushing;
  • the quality of oral cleansing decreases;
  • the brush does not vibrate as actively;
  • at the wrong moment the device turns off, although it was recently charging.

These signs may indicate other malfunctions of the device. It is better to re-read the instructions again, which describe non-working situations. If the brush is more than two years old, the probable cause of the malfunction is the battery.

You can take the device to a service center or contact a handyman. However, it is much easier and more economical to do the replacement yourself.

Battery replacement method

By default, the battery is considered a non-removable part of the brush, but if necessary, replacing it yourself is not difficult. To do this, you should study the video material on the Internet and follow these instructions:

A similar method is used when changing batteries in any Oral Bee electric toothbrushes (models professional care 500, vitality, many others). Replacement batteries can be ordered online (on Aliexpress, Taobao, Ebay), or purchased in specialized stores. The technique will extend the life of the device and save a lot of money on the purchase of a new brush.

Over the years of operation, something bad happened to it - the charge began to be enough for one time.

I found a manual on the Internet. I bought the battery on eBay for 850 rubles. It arrived in 10 days. There was the same thing on AliExpress, 400 rubles.

First of all, remove the ring from the top of the brush.
Then we insert the charger into the lower part and twist it until it spins. As soon as it starts spinning worse/slips (there is a plastic screw there), pull the white part down.


We take out the insides by snapping off the two white latches.

We unscrew the display (you need a Torx), a Chinese set of various types of screwdrivers will come in handy

We take out the spring

Unsolder 2 terminals of the old battery

Forming conclusions

Solder a new one and screw on the display.
The brush says there is no charge. After charging (the manual says about a day of charging), everything will show as it should.

Let's see how bad the old Akum is. There are no charge/discharge graphs, only photos. Because crooked software for it is only available for Windows, and even then it hurts. It was easier to take a photo.

Since I removed the brush from charging, I discharge the old battery with an Imax - I get almost 600 mAh. There is no capacity on it, the new one says 2100mAh, we will assume that the old one has a similar capacity.

I charged with a current of 0.2A for quite a long time.



Discharged with a current of 1A (it seems to me that there are more currents in the brush, but oh well)

There is 800mAh left with a discharge of up to 0.8 V. IMHO it does not discharge so deeply in the brush.

In 2011, I was lucky enough to snatch a Braun Oral-B Triumph Professional Care 9000. I walked around it in circles for six months, but the price of $100 was above my psychological maximum. Then bam and $50!!! I'm shocked, and so is the toad.

I had to take it. The brush is really cool. I wish I had one like this as a child - there would be fewer holes in my teeth. I buy replacement tips on eBay. Naturally not original. Only once did I encounter slag. Usually the spring is made of stainless steel, but here they slipped it into steel. I threw out the whole set.

Until 2016 there were no problems with the brush. In 2017 the battery began to fail. She thrashed weakly, the charge went away quickly. So I made it until 2018. In the last month there have been glitches with the charge display. Shows 100%, turn on 0%. It's time, I thought. If you type in the model on eBay, the prices for the battery are hell and Israel. Thank you, at least they indicate the size. I asked Google the right question and got the answer:

standard sizes of batteries and accumulators

It turned out that the Braun Oral-B Triumph Professional Care 9000 contains a Ni-Mn battery of size 4/5A with 1.2 volts and a nominal capacity of 2200mAh. Prices on eBay immediately became reasonable. I bought two PKCELLs for $5. Checked it on iMax-B6. 2700mA is filled, 2200mA is drained at a discharge current of 800mA. The dead one showed 1500mA.

There is an excellent disassembly video on YouTube:

The most important thing is to remove the ring before knocking out the insides:
