[0031] X Length direction Detailed implementation manners

[0032] In order to more clearly elaborate the above-mentioned objects, features and advantages of the present application, the detailed implementation manners of the present application will be described in detail in this part in combination with the accompanying drawings. In addition to the various implementation manners described in this part, the present application can also be implemented in other different ways. Without departing from the spirit of the present application, those skilled in the art can make corresponding improvements, deformations and replacements. Therefore, the present application is not limited by the specific embodiments disclosed in this part. The protection scope of the present application shall be subject to the claims.

[0033] As Figures 1 to 3 shown, an embodiment of the present application provides an oral cleaning device. The oral cleaning device can be, for example, an electric toothbrush. The electric toothbrush includes a brush handle body 1, a handle 2, a decorative ring 3, a brush head 4, a bottom cover assembly 5, a bracket assembly 6, a control device 7 and a light-emitting unit 8.

[0034] The brush handle body 1 can be a cylindrical shape extending along the length direction X ( Figures 1 to 3 the up-and-down direction in

[0035] the figure) of the electric toothbrush. The cross-section of the brush handle body 1 can be circular or oval. A cavity is provided inside the brush handle body 1, and the cavity can accommodate the bracket assembly 6, the control device 7 and the light-emitting unit 8.

[0036] The handle 2 and the bottom cover assembly 5 can be fixedly connected to the lower end of the brush handle main body 1, and the bottom cover assembly 5 can enclose the cavity of the brush handle main body 1. The lower end of the brush handle main body 1 has a handle mounting portion 11, the handle 2 can be sleeved on the handle mounting portion 11, and the diameter of the handle mounting portion 11 can be smaller than the portion in front of the handle mounting portion 11, so that the handle 2 and the brush handle main body 1 are smoothly transitioned. The handle 2 and the handle mounting portion 11 are closely fitted, so that the gap between the brush handle main body 1 and the handle 2 is small, avoiding the accumulation of stains and dirt in the gap, and making the electric toothbrush beautiful. Patterns can be printed on the surface of the handle 2.

[0037] It can be understood that here, the head side of the electric toothbrush is referred to as the front side.

[0038] Furthermore, the brush handle main body 1 can be made of a light-transmitting material, and the optional color of the brush handle main body 1 is dark (for example, it can be black). The handle 2 is made of a non-light-transmitting material, for example, the handle 2 can be made of an aluminum alloy material. The circumferential surface of the brush handle main body 1 is complete without openings. The part of the brush handle main body 1 not surrounded by the handle 2 can be light-transmitting, that is, the part of the brush handle main body 1 not surrounded by the handle 2 is a light-transmitting area. Using a dark light-transmitting material can prevent the brightness inside the brush handle main body 1 from being too high, enabling the components inside the brush handle main body 1 to be clearly seen, and can also protect the observer's eyesight to a certain extent, avoiding discomfort caused by direct strong light.

[0039] The bracket assembly 6 includes a bracket 61, a motor 62, and a battery 63. Both the motor 62 and the battery 63 can be connected to the bracket 61, and the battery 63 is connected to the motor 62 to supply power to the motor.

[0040] The light-emitting unit 8 can be connected to the bracket assembly 6, and the light-emitting unit 8 is correspondingly arranged with the light-transmitting area of the brush handle main body 1. The light-emitting unit 8 can include a back lamp holder 81, a back light bar 82, and a light-shielding plate 83. The back lamp holder 81 can be mounted on the motor 62, the back light bar 82 can be connected to the back lamp holder 81, and the light-shielding plate 83 can cover the surface of the back light bar 82. The light-shielding plate 83 can be made of a non-light-transmitting material, and the light-shielding plate 83 can be provided with a number of light-transmitting holes. Part of the light emitted by the back light bar 82 can pass through the light-transmitting holes, and the light-shielding plate 83 is used to block part of the light emitted by the back light bar 82 to avoid too high brightness. The light-emitting unit 8 can illuminate the inside of the brush handle main body 1, and the observer can clearly and intuitively understand the working state of the electric toothbrush through the light-transmitting area of the brush handle main body 1.

[0041] The control device 7 can be connected to the bracket assembly 6. The control device 7 includes a circuit board assembly 71, a display screen 72, and a touch component 73. The circuit board assembly 71 can be connected to the bracket 61. The circuit board assembly 71 is used to receive and send signals to control the electric toothbrush to perform corresponding operations, and to control the operation of the light-emitting unit 8. The display screen 72 is correspondingly arranged with the light-transmitting area of the brush handle body 1, and the display screen 72 itself may not emit light.

[0042] The touch component 73 includes a sensing touch frame 731 and a touch panel 732 arranged on the sensing touch frame 731. The touch component 73 can be arranged on the back and / or beside the display screen 72, and can perform a touch operation on the touch panel 732 through the brush handle body 1. The user can select a suitable working mode by touching the display screen 72. Arranging the display screen 72 and the touch component 73 inside the overall light-transmitting brush handle body 1 can avoid opening holes on the circumferential surface of the brush handle body 1 to alleviate or solve the problem of water ingress.

[0043] The light-emitting unit 8, the control device 7, the motor 62, and the battery 63 are all connected to the bracket 61, so that the light-emitting unit 8, the control device 7, the motor 62, and the battery 63 can be loaded into the cavity of the brush handle body 1 together from the opening at the lower part of the brush handle body 1 after being installed on the bracket 61.

[0044] Optionally, the display screen 72 of the control device 7 and the light-emitting unit 8 can be arranged on the front and back sides of the brush handle body 1 facing opposite directions. For example, the control device 7 can face the front (i.e., Figure 1 the right side in Figure 1 i.e., the side with the bristles of the brush head), and the light-emitting unit 8 can face the back (i.e.,

[0045] the left side in
