Legend has it that lazy people change the world.

In fact, it is because of "laziness" that there are more simple and cost-effective solutions. For example, lazy laundry has a washing machine; Lazy farming has automatic seeders and harvesters; Lazy climb stairs, with the elevator. There was a news before that two foreigners were lazy in brushing their teeth and invented a toothbrush with toothpaste coating on their tongue, so that they could brush their teeth clean by licking up and down in their mouth. In fact, they are not the laziest. How tired are they to move their tongues? The toothbrush can be vibrated directly with sound waves, which saves energy. It doesn't need to use your hands or move your tongue. It is also clean.

To get back to business, we recently experienced the rechargeable acoustic vibration toothbrush of Baili UK. The crowdfunding price of more than 200 yuan is less than half of that of Philips, Panasonic and other international brands, but the performance and configuration are not poor. It should be noted that the acoustic toothbrush is actually a mechanical toothbrush. It does not mean brushing teeth with acoustic waves, but uses electromagnetic drive motors to move at a high speed and drive the toothbrush head to vibrate at a high frequency. Because the vibration frequency is similar to that of acoustic waves, it is called the acoustic electric toothbrush. On the market, the acoustic electric toothbrush vibrates 31000 times per minute, but the maximum vibration of this toothbrush reaches 48000 times per minute. It is said that it has a technical patent, which is regarded as the "flagship" frequency. The cleaning, whitening, polishing, massage and sensitive functions on the back of the packaging box correspond to the five vibration frequency modes of Baili British, and will be introduced later.

Baili British rechargeable acoustic vibration toothbrush is equipped with a charging base, a rechargeable brush handle and two brush heads as standard. Among them, the brush head is a consumable, which is usually replaced once every three months, so the standard configuration can be used for half a year. However, the toothbrush head of Baili British is very cheap, less than 21, and the use cost is very low.

This toothbrush uses inductive charging, so there are no metal contacts on the charging base and the toothbrush handle. The indicator light will display the current power state after the toothbrush handle is inserted. The two toothbrush heads also have special positions on the base, but it may be a simple version of the experience, and there is no toothbrush head protective cover. It is recommended to equip two brush head protective covers as standard, which can effectively prevent the spare brush head from being polluted.

Because the toothbrush is relatively long, I was worried about the stability of the charging base. However, on the one hand, the center of gravity of the toothbrush is lower, and on the other hand, there are three foot pads with good anti-skid performance at the bottom of the base, so the base is also very stable after the toothbrush is placed. According to the nameplate on the base, the charging power consumption of Baili English toothbrush is very low, only 1.2W, and it has its own overcharge protection, so you don't have to worry about the battery damage after a long charge.

Baili British rechargeable acoustic vibration toothbrush is available in white and black. Personally, the black toothbrush is more suitable for men. It is rough and delicate, and has a good frosting feel. From top to bottom, there are power supply and mode switch keys, five indicators for tooth brushing mode, and charging and running indicators. The orange round pads with patterns on both sides of the upper part exactly correspond to the thumb and index finger when brushing teeth in different positions, improving the grip and comfort. The overall workmanship is good.

The metal handle on the top of the brush handle is connected with the internal magnetic suspension motor, and the periphery is filled with silica gel. When installing the brush head, it needs to be inserted slightly with a little force. There is a 0.5mm gap between the toothbrush head and the brush handle. These are normal phenomena. After all, it is a high-frequency vibration environment. The stable place should be firm, and the loose place should have room. The installed "three circumference" of the toothbrush is 30.5 * 28.8 * 245.3mm, which looks quite long, but the weight of 112.5g does not feel heavy.

There is an IPX7 mark at the bottom of the brush handle, which means that the toothbrush can work normally for more than 30 minutes in the water below 1 meter. Then, in our daily use, we can wash the body with water directly under the tap. In the following picture, it can be seen that both the brush handle and the charging base are immersed in water, and they operate normally and vibrate without any problems.

In terms of working mode, Baili British rechargeable acoustic vibration toothbrush has five options: cleaning, whitening, polishing, massage, and sensitivity. By continuously pressing the key to open and freely switching, it is easy to identify the current mode from the sound, and the functions of 30 second pause for a vibration, 2 minute automatic shutdown, and boot mode memory also ensure that it is easy to use. Next, extend the brush head half into the water, and visually display the vibration state of different modes through water spray.

1. In the cleaning mode, that is, in the standard mode, the brush head vibrates 31000 times per minute for daily use.

2. Whitening mode, the brush head vibrates 41000 times per minute to remove the stain on the tooth surface, which is my favorite.

3. Polishing mode is a powerful mode that can remove more than twice the number of dental plaque. The brush head vibrates 48000 times per minute.

4. Massage, vibration with a little rhythm, can gently stimulate the massage gums, brush head vibration 31000 times per minute.

5. Sensitive, suitable for people with swollen gums and bleeding, with the slowest frequency. The brush head vibrates 28000 times per minute.

The noise control of the electric toothbrush is also important, and no one wants to deafen their ears at a good time for brushing. Using a noise tester to test the noise of Baili UK under various working modes, the distance from the simulated daily noise is about 15cm, which is basically about 55dB, which is equivalent to the number of decibels we talk in an ordinary room. Good results.

When this experience was written, I had used the Baili English toothbrush for 2 weeks, and only fully charged when I first used it. Now it shows that there is still half of the power. It is said that a full charge can last for 6 weeks in normal use. Basically, you don't need to bring a charging base on business trips.

By experiencing this Baili British rechargeable acoustic vibration toothbrush, I feel that lazy people are really lazy.

First of all, the electric toothbrush saves time and effort compared with manual toothbrushing. It does not need to throw back and forth hard and boring, nor does it need to worry about whether the toothbrushing method is scientific. It directly changes the area in 30 seconds, and takes care of every tooth in 2 minutes. It is scientific and effective.

Secondly, the electric toothbrush has a better cleaning effect than the traditional toothbrush. You may not be used to it at the beginning, but you like this tremor in a few days. Select the polishing mode and press down slightly. After a few days, you will find that the teeth are whiter than before. Because experiments have proved that the electric toothbrush can remove 38% more plaque than the manual toothbrush, with 30000 to 40000 vibrations per minute, even if the Kirin arm is useless.

Thirdly, the electric toothbrush protects teeth more than manual toothbrushing. The traditional toothbrushing method moves forward and backward with different strength, which is easy to damage the gingival tissue. However, the constant frequency of the electric toothbrush can be completely avoided only by maintaining a good direction.

Therefore, it is only a matter of time before the sonic vibration toothbrush replaces the traditional toothbrush.
