an electric toothbrush

Abstract

The invention relates to the technical field of tooth cleaning equipment, in particular to an electric tooth cleaning device, comprising a tooth cleaning device handle, a brush head, a speed regulating device, a power supply, a motor and a transmission device. Linearly distributed holding grooves, each holding groove is slidably installed with abutting blocks, the upper and lower ends of the abutting blocks are provided with limit components, multiple abutting blocks are fixedly connected to vertical beams, and auxiliary support components are arranged at the bottom of the tooth scaler handle , the auxiliary support assembly is driven by the driving mechanism to perform telescopic movement at the bottom of the handle of the tooth scaler. By setting a plurality of holding grooves, the holding area of ​​the handle of the toothbrush can be enlarged, so that the user's hand can better hold the electric toothbrush, and the user can easily hold the brush of the electric toothbrush without special force. The handle avoids that when the brush head is just working in the oral cavity, it is very easy to smash the user's cavity, causing bleeding gums and other situations, effectively improving the safety performance of the electric toothbrush.

Description

technical field [0001] The invention relates to the technical field of tooth cleaning equipment, in particular to an electric tooth cleaning device. Background technique [0002] With the development of science and technology, electric toothbrushes appear as a new form of toothbrush. According to the survey, electric toothbrushes are more scientific and effective than ordinary toothbrushes, which can remove plaque, reduce oral diseases such as gingivitis, periodontal disease and bleeding gums, so they are increasingly popular. [0003] The current electric toothbrush is mainly based on the principle of vibration. This type of electric toothbrush causes the brush head to generate high-frequency vibration through the rapid rotation or vibration of the motor core, which instantly decomposes the toothpaste into fine foam and deeply cleans the teeth; The tissue has a massage effect. [0004] Because the electric toothbrush uses a high-speed vibrating movement to drive the brus...

AI Technical Summary

Problems solved by technology

[0004] Since the electric toothbrush uses a high-speed vibrating movement to drive the brush head to rotate or vibrate to achieve the effect of cleaning teeth, it will inevitably vibrate during the use of the electric toothbrush. It is necessary to hold the handle of the electric toothbrush firmly, otherwise the electric toothbrush will fall out of the hand if you are not careful and the existing electric toothbrushes are mostly set in the shape of a smooth long rod in order to ensure the smoothness of the appearance and the effect of portability, which makes it difficult for the toothbrush to be stably placed on the washstand. It is easy to cause the toothbrush to fall due to the unstable center of gravity
