Description

Brush head connector and its electric toothbrush

technical field

The utility model relates to the technical field of protective shells, in particular to a brush head connector and an electric toothbrush thereof.

Background technique

As shown in Figure 1, the brush head connector 1 of an ordinary electric toothbrush is a truncated cone, with two main purposes: one is to provide a surrounding shell for the vibration motor, and the other is connected to the brush head to transfer the vibration energy of the vibration motor to the brush head. Disadvantages of this method: it takes up a lot of space, and there is a lot of vacant space in the front part of the motor vibrator. When connecting with the brush head, the front end and the brush head part do not form a close fitting contact, which will waste part of the vibration energy.

Utility model content

The purpose of the utility model is to provide a brush head connector with a compact structure and good vibration effect and an electric toothbrush thereof.

For this purpose, the utility model adopts the following technical solutions:

A brush head connecting piece, the end of the brush head connecting piece is provided with a ball head housing part for matching with an eccentric block of a drive motor, and the ball head housing part is inserted into the installation cavity of the toothbrush head.

Wherein, the brush head connecting part matches with the drive motor extending from one end of the handle of the toothbrush.

Wherein, the ball head shell part is a cylindrical shell with a ball head at one end.

Wherein, the other end of the ball head housing part is provided with a switch fixing housing aligned with the outer surface of the toothbrush head, and a button for controlling the driving motor is provided on the side wall of the switch fixing housing.

Wherein, the circumference of the base of the fixed switch housing is convexly provided with a positioning protrusion for matching with the toothbrush cover.

Wherein, the outer diameter of the switch fixing housing is larger than the outer diameter of the ball head housing part.

Wherein, the switch fixing shell and the ball head shell are integrally formed by plastic.

An electric toothbrush, comprising the brush head connector described in any one of the above.

Beneficial effects of the utility model: the utility model provides a brush head connector, the end of the brush head connector is provided with a ball head shell for matching with the eccentric block of the drive motor, the ball head shell The body is inserted into the installation cavity of the toothbrush head. The setting of the ball head housing part not only facilitates the insertion and extraction of the toothbrush head, but also effectively protects the drive motor, and makes the structural connection between the ball head housing part and the eccentric block compact, saving space, and facilitating the carrying of the electric toothbrush.

detailed description

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

As shown in Figure 2 and Figure 3, the end of the brush head connector in this embodiment is provided with a ball head housing part 2 for matching with the eccentric block 31 of the drive motor 3, and the ball head housing part 2 is inserted into the In the installation cavity of the toothbrush head 4, the brush head connector is matched with the drive motor 3 extending from one end of the toothbrush handle, and the ball head shell part 2 is a cylindrical shell with a ball head at one end.

The above-mentioned structural design, the setting of the ball head shell part, the overall shape is streamlined, and the front end is in the shape of a semicircle. This structural design greatly saves the space of the ball head shell, makes the structure compact with the eccentric block of the drive motor, and closely cooperates with the brush head, which is conducive to smoother energy transmission of the drive motor and less energy waste. A compact fit and less energy waste also means less noise.

In this embodiment, the other end of the ball head housing part 2 is provided with a switch fixing housing 21 aligned with the outer surface of the toothbrush head 4, and the side wall of the switch fixing housing 21 is provided with buttons for controlling the drive motor 211, the root circumference of the switch fixed housing 21 is convexly provided with a positioning protrusion 212 for matching with the toothbrush cover, the outer diameter of the switch fixed housing 21 is greater than the outer diameter of the ball head housing part 2, the switch fixed housing 21 and the toothbrush cover The 2 parts of the ball head housing are integrally formed with plastic. The brush head connector designed in this way can be conveniently connected to the toothbrush head, and the connected electric toothbrush has a compact structure and high energy transfer efficiency.

In this embodiment, as shown in FIG. 3 , an electric toothbrush includes the above-mentioned brush head connector.

The technical principles of the present utility model have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the utility model, and cannot be construed as limiting the protection scope of the utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific implementations of the present utility model without creative work, and these forms will all fall within the protection scope of the present utility model.
