[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] In the embodiment of the present utility model, a visual electric toothbrush is provided. Please refer to Figure 1-Figure 6 The visualized electric toothbrush includes a brush handle 10 and a brush head 20; the brush handle 10 includes a driving assembly 110 and a camera module 120, the driving assembly 110 has a motor 1110 and a transmission shaft 1120, the motor 1110 drives the transmission shaft to rotate, the camera module 120 is arranged at one end of the transmission shaft 1120 close to the brush head 20, and the transmission shaft 1120 is hollow and is provided with an FPC30 for connecting the camera module 120; the brush head 20 is provided with an optical channel 210, when the brush head 20 and the brush handle 10 are assembled, the camera module 120 can collect image information through the optical channel 210.

[0029] According to the visualized electric toothbrush in the above embodiment, the camera module 120 is arranged on the transmission shaft 1120 of the driving assembly 110, the transmission shaft 1120 is hollow or partially hollow, and the camera module 120 is connected through the FPC30, so as to control and power the camera module 120. The brush head 20 is provided with an optical channel 210, and when the brush head 20 is inserted into the oral cavity, the camera module 120 can collect image information. In this way, the purpose of the electric toothbrush being able to view the internal condition of the oral cavity can be achieved. The implementation of the visualized electric toothbrush in this embodiment can realize a visualized electric toothbrush with a simple structure and lower production cost.

[0030] Please note that, please refer to Figure 5 and Figure 6 The brush handle 10 generally has a battery and a circuit board inside, the FPC 30 is electrically connected to the circuit board, and the circuit board is electrically connected to the battery. A plurality of buttons are provided on the housing of the brush handle 10, and the circuit board is controlled by the buttons to control the vibration amplitude of the motor 1110 or start (turn off) the camera module 120.

[0031] Alternatively, a communication module is also provided on the circuit board to upload the image information collected by the camera module 120 through remote wireless transmission. In addition, the remote receiving end can also issue instructions to control the circuit board to adjust the vibration frequency of the motor 1110 or the switch of the camera module 120.

[0032] Specifically, Bluetooth communication, wifi communication or cellular network can be used to realize the connection between the visualized electric toothbrush of the present invention and the remote control terminal. The remote control terminal is generally a mobile device, such as a mobile phone or a tablet computer.

[0033] There are mainly two situations for the structure of the drive shaft 1120: the first is that the drive shaft 1120 is completely hollow, the FPC30 is passed through the drive shaft 1120, and then electrically connected to the circuit board; the second is that the drive shaft 1120 is partially hollow, and a through hole is provided on the surface of the drive shaft 1120 for connecting the hollow part of the drive shaft 1120, and the FPC30 passes through the hollow part and the through hole of the drive shaft 1120 in turn and is electrically connected to the circuit board.

[0034] In some specific embodiments, the area of ​​the brush head 20 corresponding to the light channel 210 is made of transparent material.

[0035] A through hole can be directly formed on the brush head 20, but this will cause brushing water and foam to enter the light channel 210, thereby reducing the waterproof level of the electric toothbrush. Therefore, the area of ​​the brush head 20 corresponding to the light channel 210 can be made of a transparent material.

[0036] Specifically, a transparent area may be separately molded during injection molding to form an entrance for light to enter the light channel 210 .

[0037] Alternatively, the brush head 20 except the bristle part is made of transparent material, such as transparent plastic. The material of transparent plastic includes polymethyl methacrylate, polycarbonate, polypropylene, polyethylene and the like.

[0038] Of course, transparent materials such as glass can also be used, but glass materials are relatively brittle, not only not conducive to molding, but also may be broken due to the high-speed vibration of the transmission shaft 1120. Therefore, the transparent material is preferably plastic.

[0039] In some specific embodiments, the viewing angle of the camera module 120 is smaller than the viewing angle of the area of ​​the brush head 20 corresponding to the light channel 210 .

[0040] In this embodiment, there is at least one transparent area on the surface of the brush head 20, and the viewing angle of this transparent area must be greater than the viewing angle of the camera module 120 to prevent the imaging of the camera module 120 from being blocked.

[0041] In some specific embodiments, please refer to Figure 3-Figure 6 A lens 2110 is provided in the light channel 210 , and the lens 2110 is used to guide the light entering the light channel 210 from outside the brush head 20 to reach the camera module 120 .

[0042] In this embodiment, the transmission shaft 1120 is generally not too long, so the camera module 120 disposed on the transmission shaft 1120 is not close to the bristles of the brush head 20. When brushing teeth, users generally only insert the bristles into the oral cavity, so in order to make the imaging position of the camera module 120 close to the bristles, the optical channel 210 is generally arranged along the axial direction of the brush head 20, and is opened at one end close to the bristles. Through the lens 2110, the light from the opening is guided to change the direction of the light so that the camera module 120 can collect image information at the opening. In this way, the image information collected by the camera module 120 is closer to the bristles.

[0043] The lens 2110 generally changes the direction of light by reflection, and of course this embodiment does not exclude some refractive lenses 2110.

[0044] It should be noted that the optical channel 210 can also be introduced by optical fiber.

[0045] Optical fiber refers to man-made fibers used to transmit light. It is also called optical fiber, or optical fiber for short. The basic structure is a cylindrical slender filament with a diameter between 1 and 100 microns. The most commonly used material for making optical fibers is silica (quartz), and multi-component glass or organic glass is also used. The materials of optical fibers must be highly transparent and have very high requirements for material purity. For example, the material purity of optical fibers used for communication is required to reach more than 8 9. If the purity of the material is low, the light will decay quickly during transmission. The manufacturing process of optical fiber is to melt the material in a high-temperature furnace and draw it into filaments at high speed. The drawing process requires that the drawn filaments are uniform in thickness and meet optical requirements. There are two types of optical fibers used: one is reflective optical fiber, which uses total reflection of light to propagate light along a refractive path in the optical fiber; the other is refractive optical fiber, which uses a gradual change in the refractive index to propagate light along a curved path in the optical fiber.

[0046] In some specific embodiments, a light (not shown) is further provided, and the light (not shown) is used to provide supplementary light to the camera module 120 .

[0047] The environment in the oral cavity is relatively dim, so supplementary light is needed, and the lamp (not shown) can emit white light for supplementary light. Alternatively, the light is ultraviolet light, and through ultraviolet light irradiation, the image collected by the camera module 120 makes it easier for the user to identify the location of dental plaque.

[0048] In some specific embodiments, the lamp is disposed at one end of the transmission shaft 1120 close to the brush head 20 .

[0049] In this embodiment, the lamp and the camera module 120 are arranged together. The light emitted by the lamp enters the oral cavity through the light channel 210 and then enters the light channel 210 after being reflected, and the camera module 120 collects the image.

[0050] It should be noted that, at this time, the light and the camera module 120 can share a FPC 30, or each can be provided with an FPC 30.

[0051] In some specific embodiments, the light is disposed on the surface of the brush handle 10 .

[0052] In this embodiment, the lamp is disposed on the outer shell of the brush handle 10, preferably near the brush head 20. The lamp emits light, which is irradiated into the oral cavity and then reflected into the light channel 210, so that the camera module 120 collects image information.

[0053] In some specific embodiments, the camera module 120 is detachably connected to the transmission shaft 1120 .

[0054] The camera module 120 is detachably connected to the transmission shaft 1120, which can facilitate consumers to select electric toothbrushes of different specifications. The main accessories of ordinary electric toothbrushes and visual electric toothbrushes are the brush head 20 and the camera module 120. An installation position can be reserved on ordinary electric toothbrushes, and the transmission shaft 1120 is partially hollow or completely hollow. When consumers need to transform the original electric toothbrush into a visual electric toothbrush, they only need to purchase the corresponding accessories to achieve the modification.

[0055] In some specific embodiments, the camera module 120 is clamped on the transmission shaft 1120 .

[0056] The camera module 120 is clipped onto the transmission shaft 1120, which is a relatively quick installation method and is more easily accepted by general consumers.

[0057] It should be noted that the camera module 120 can also be installed on the transmission shaft 1120 by means of screw connection or magnetic core.

[0058] In some specific embodiments, the brush handle 10 has a bracket 130, and the brush head 20 has a buckle 220. The buckle 220 can be inserted into the bracket 130 to connect the brush head 20 and the brush handle.

[0059] The brush head 20 and the brush handle 10 of the electric toothbrush are generally tightly mounted. Usually, a bracket 130 is provided on the brush handle 10, and a recess is provided on the bracket 130. The buckle 220 on the brush head 20 is inserted into the recess to fix the brush head 20 and the brush handle 10.
