Description

Oral Electric Cleaner

technical field

The invention relates to the technical field of oral cavity cleaners, in particular to an electric oral cavity cleaner used in conjunction with a gel-like dentifrice.

Background technique

Daily oral cleaning generally includes teeth, interdental and tongue cleaning, etc. Among them, toothbrush is often used for tooth cleaning, and a certain pressure is applied to the toothbrush to make the bristles move on the surface of the teeth to adapt to the different shapes of the teeth, and drive the particles in the toothpaste to interact with the teeth. The relative movement of the surface produces cleaning, grinding and polishing effects, but this method has two problems. One is that the contact surface between the bristles and the teeth is small. Damage to soft tissues such as gums; second, the shape of the teeth is complex and changeable. Even if you maintain good brushing habits and adopt the correct brushing posture, there are still many dead spots that cannot be cleaned well, such as between the teeth and near the gum line. Clinically, dentists often recommend that while adhering to the correct brushing habits, use dental floss or interdental brushes to clean the dirt between the teeth, use a toothpick to clean the dirt near the gum line, and use a tongue scraper for the tongue coating on a regular basis. clean.

The above cleaning methods are firstly cumbersome and difficult for ordinary people to persist for a long time, and secondly, the cleaning effect is not good, and there are many dead spots that cannot be cleaned regularly and effectively.

The existing improved method is to use an electric toothbrush, mainly through the vibration or vibration of the bristles. Since this vibration or vibration is much higher than manual brushing frequency, it can achieve a better cleaning effect than manual brushing, but it still fails to solve the problem. Disadvantages of cleaning dead spaces such as between teeth and under the gum line.

It is another direction at present to clean the teeth with a mold cover that can automatically fit the surface of the teeth. The utility model with the application number of 200920136549.8 discloses a kind of dental arch type full-mouth toothbrush, in the arch (U-shaped) groove Planted with bristles, through the occlusion of the upper and lower teeth, all teeth are cleaned at the same time. The improved technical solution is to use the vibration generator to drive the bristles in the U-shaped groove to vibrate at high frequency until the effect of fast and synchronous cleaning of all teeth is achieved, such as the technical solution published in the utility model with application number 201820025660.9. These technical solutions can clean all the teeth at the same time, and the cleaning speed is much higher than that of ordinary toothbrushes and electric toothbrushes, but the disadvantage is that the contact force between the bristles and the teeth is small and difficult to adjust, making it difficult to clean them; Small, it is difficult to brush all the outer surfaces of the teeth, let alone effectively clean between teeth, below the gum line, etc.
