Description

an electric toothbrush

technical field

The invention belongs to the technical field of electric toothbrushes, and particularly relates to an electric toothbrush.

Background technique

The electric toothbrush uses a high-speed vibrating movement to drive the brush head to vibrate to achieve the effect of cleaning teeth. Compared with the traditional manual toothbrush, the electric toothbrush is driven by electricity, and the brush head moves at a speed of thousands or even tens of thousands of times per minute, and the efficiency is much higher than that of the manual toothbrush; at the same time, the electric toothbrush can form a cavitation effect in the periodontal. In order to achieve the removal of periodontal bacteria and impurities, its cleaning range can cover all parts of the periodontal. The bristles of the vibrating brush head transmit cleaning energy to the surface of the teeth and gums. On the one hand, it loosens the adhesion of plaque, tartar and fine tartar to the teeth, and destroys the parasitic reproduction of bacteria in the gingival pockets and the hidden places on the tooth surface. The energy transmitted to the surface of the gums by the bristles touching the gums further penetrates into the inside of the gums. After acting on the cell membrane, it accelerates blood circulation, promotes metabolism, inhibits gum inflammation and gum bleeding, and prevents gum recession. Not only that, because the electric toothbrush is easy to operate and more intelligent, it can bring great convenience to children and disabled people who are not good at brushing their teeth.

Due to the high manufacturing cost of traditional electric toothbrushes, the price is generally tens of yuan or even hundreds of yuan. In order to reduce the cost of use and win the favor of consumers, sales manufacturers usually give away multiple toothbrush heads for easy replacement. On the one hand, multiple spare toothbrush heads are easily polluted or even lost if they are placed for a long time; on the other hand, if one toothbrush head is recommended to be used for about 3 months, and an electric toothbrush with two toothbrush heads is given, it is about 100 yuan for one toothbrush head. The electric toothbrush can only be used for nine months, and the cost of use is much higher than that of ordinary toothbrushes that cost a few dollars or even a dozen dollars. This price puts a lot of people off.

The applicant has been devoted to the research and development of electric toothbrushes for many years. In recent years, the applicant has developed an electric toothbrush auxiliary device, which can realize the function of the electric toothbrush by purchasing an ordinary toothbrush and installing the auxiliary device. However, the motor of the auxiliary device is arranged on the toothbrush head, and the volume is greatly limited, and the vibration intensity of the motor is closely related to the volume of the motor, which limits the vibration intensity of the toothbrush.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an electric toothbrush, which removes the restriction on the volume of the motor by changing the installation position of the motor, and can increase the vibration intensity according to the needs of the user.

In order to achieve the above purpose, the technical solution of the present invention is: an electric toothbrush, comprising a toothbrush body and an electric auxiliary part; the electric auxiliary part includes a control cavity and a vibration part; wherein,

The control cavity is detachably connected to the handle of the toothbrush body through the first snap connection, the control cavity is provided with a battery and a control main board, and the battery is connected with the control main board;

The vibration part is provided with an electric motor, and the vibration part is detachably connected to the end of the handle close to the toothbrush head through the second snap connection piece;

The control cavity and the vibration part are connected through a connecting part, and the electric motor is connected with the control main board through a connecting cable embedded in the connecting part.

According to the electric toothbrush of the present invention, preferably, the vibration part includes a sealed shell structure, and the motor is arranged in the sealed shell structure.

According to the electric toothbrush of the present invention, preferably, the control cavity is further provided with a USB socket, the USB socket is connected to the control motherboard, and a sealing cover is also provided on the USB socket.

According to the electric toothbrush of the present invention, preferably, the connecting portion is a flexible connecting portion made of silica gel.

According to the electric toothbrush of the present invention, preferably, the control cavity and the sealing shell structure are made of silica gel, and the connecting portion is integrally formed with the control cavity and the sealing shell structure.

According to the electric toothbrush of the present invention, preferably, the first snap connection piece and the second snap connection piece are two sets of claw structures.

The beneficial effects of the present invention are:

In the electric toothbrush of the present invention, the main body of the toothbrush is an ordinary toothbrush, which has the function of an electric toothbrush through the cooperation with the electric auxiliary parts, and the purchase of the ordinary toothbrush is convenient and low in cost. For brushing operation, its volume is not limited, and the vibration intensity can be increased by setting a large motor according to needs.
