How Electric Toothbrushes Work
At present, the mainstream electric toothbrushes on the market can be divided into three categories, namely rotary electric toothbrushes, sonic electric toothbrushes, and hybrid electric toothbrushes. The principle of the rotary toothbrush is simple. That is, the motor drives the circular brush head to rotate, and the friction effect is enhanced while performing the ordinary brushing action. Considerable wear and tear, long-term use is not recommended. The Oral-B electric toothbrush mainly represents it.
The vibration type toothbrush has an electrically driven vibration motor inside, which can make the brush head generate a high-frequency swing perpendicular to the direction of the brush handle, but the swing amplitude is minimal. Generally, about 5 mm up and down, and the most significant swing in the industry is 6 mm—mainly represented by Philips electric toothbrushes.
The hybrid-electric toothbrush adopts the exclusive patented stacking hair planting technology. There is a particular elastic space between the bristle base cavity and the back shell of the brush head, and there is also a specific adaptable space between the bristle base and the pit. The transmission shaft rotates at high speed. Driven by power, each tuft of bristles can maintain an independent 360° high-speed rotation while maintaining irregular vibration in all directions (up/down/front/rear/left/right). No dead ends, 360° cleaning care. Phileas electric toothbrushes mainly represent them.
On the one hand, when brushing your teeth, the high-frequency oscillating brush head can efficiently complete the action of brushing your teeth. On the other hand, the high-frequency vibration exceeding every minute also produces a large number of tiny bubbles in the mixture of toothpaste and water in the mouth. When the bubbles burst, The resulting pressure can penetrate deep between the teeth to clean the dirt.
How to choose an electric brush?
In this regard, how to choose an electric toothbrush and what should be paid attention to? The benevolent see benevolence, and the wise see wisdom. There are mainly the following aspects:
- Budget and price For the general consumer group, Philips series of several thousand RMB are generally not open. Two or three hundred RMB is a price that everyone thinks can buy a good electric toothbrush, and it is also an acceptable price.
- Mode, sensitive mode If the teeth are not very good, users will be very concerned about whether the electric toothbrush they use has a sensitive manner. Today’s electric toothbrushes have different methods to meet the needs of daily cleaning and the needs of people with sharp teeth. There are not many patterns in essence, and too many are unnecessary.
- Bristles, Generally speaking, the selection of the brush head should follow the principle of “small brush head, moderately soft and hard bristles.” Medium-hard bristles also have higher cleaning efficiency, too soft bristles cannot remove dirt, and too stiff bristles are easy to damage the gums and should not be used.
- When choosing an electric toothbrush, be sure to choose one that does not knock your teeth. Otherwise, it will feel like your teeth have been knocked out.
- Cleaning power This is the most basic and most important thing. Buying an electric toothbrush is to brush more cleanly. Regarding the cleaning power, you can see the bristles’ vibration frequency and hardness.
- Charging method The charging methods of electric toothbrushes I know are divided into two types: USB and induction charging. We all agree that USB is very bloody. The bathroom is so big; everyone usually needs to put down the electric toothbrush to set it, which is troublesome to occupy the space. So inductive charging is what we think is the best.
