Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] This utility model discloses an electric toothbrush with a pressure-sensitive button, such as... Figure 1-8 As shown, it includes: a toothbrush head 10 and a toothbrush main unit 20. The toothbrush main unit 20 is used to drive the toothbrush head 10 to move in order to achieve electric teeth cleaning.

[0033] The toothbrush main unit 20 includes a handle tube 21, a first mounting bracket 22 is installed inside the handle tube 21, a control board 23 is fixedly installed on the side wall of the first mounting bracket 22, a pressure sensor 24 and a sensing element 25 are sequentially installed on the control board 23, a capacitive touch area 233 is provided on the control board 23 that is directly opposite to the sensing element 25, and a pressing position 213 corresponding to the sensing element 25 is provided on the outer wall of the handle tube 21.

[0034] It should be noted that by pressing the pressing position 213 with external pressure, the sensing element 25 squeezes the pressure sensor 24. The control board 23 recognizes and converts the pressure, realizing the button function. This provides an electric toothbrush with a pressure-sensing button, which eliminates the need for traditional mechanical buttons, prevents dust or moisture from entering the electric toothbrush, and extends the service life of the electric toothbrush.

[0035] like Figure 3 , Figure 5 and Figure 8As shown, the handle sleeve 21 is provided with a guide rail 211, and the side wall of the first mounting bracket 22 is provided with a protrusion 221 that fits against the guide rail 211. In specific implementation, the number of protrusions 221 is set to two, and the number of guide rails 211 is set to four, with each protrusion 221 corresponding to two guide rails 211; the protrusions 221 and guide rails 211 are slidably connected. It should be noted that the guide rails 211 limit the control plate 23 on the first mounting bracket 22. When the sensing element 25 presses the pressure sensor 24, the control plate 23 has no range of motion, allowing the pressure sensor 24 to accurately sense the external pressure.

[0036] like Figure 5 and Figure 8 As shown, the handle sleeve 21 has a slot 212, and one end of the first mounting bracket 22 has a buckle 222 that engages with the slot 212. In specific implementation, the number of slots 212 and buckles 222 is set to two, and the buckles 222 are elastic; by engaging the buckles 222 with the slots 212, the first mounting bracket 22 is securely installed in the handle sleeve 21, preventing the first mounting bracket 22 from moving.

[0037] like Figure 3 and Figure 6 As shown, the control board 23 has a perforated hole 231 corresponding to the pressure sensor 24. It should be noted that, through the perforated hole 231, when the sensing element 25 squeezes the pressure sensor 24, it can provide deformation space for the pressure sensor 24, so that the pressure sensor 24 can better sense the external pressure.

[0038] like Figure 3-7 As shown, the sensing element 25 includes a sensing body 251 with an inner cavity 2511. A first pressing boss 252 and a second pressing boss 253 are disposed opposite each other on the sensing body 251, with the second pressing boss 253 located within the inner cavity 2511. In practice, the sensing body 251, the first pressing boss 252, and the second pressing boss 253 are all integrally formed. The first pressing boss 252 contacts the inner wall of the handle cylinder 21; the second pressing boss 253 facilitates the compression of the pressure sensor 24, allowing the user to quickly perceive the pressing operation.

[0039] like Figure 7 As shown, the second pressing boss 253 has a pressing surface 2531 that is planar. It should be noted that, since the pressing surface 2531 is planar, the second pressing boss 253 can better contact the pressure sensor 24, and the pressure sensor 24 can more accurately sense the external pressure.

[0040] like Figure 7As shown, the sensing body 251 is provided with a limiting post 254, and the control plate 23 is provided with a limiting hole 232 that engages with the limiting post 254. The limiting post 254 is provided with a limiting surface 2541 and a guide slope 2542. The limiting surface 2541 contacts the control plate 23, and the guide slope 2542 facilitates the limiting post 254 passing through the limiting hole 232. In specific implementation, the limiting post 254 and the sensing body 251 are integrally formed. The number of limiting posts 254 is set to three. After the limiting post 254 passes through the limiting hole 232, it can engage with the control plate 23, which facilitates quick and easy installation of the sensing element 25.

[0041] like Figure 1-8 As shown, the sensing element 25 is made of conductive silicone. It should be noted that, because the sensing element 25 is made of conductive silicone, the control board 23 has a capacitive touch area 233 directly opposite the sensing element 25, used to sense changes in capacitance. When the operator touches the pressing position 213 of the handle cylinder 21, the capacitance of the capacitive touch area 233 changes, and this change is transmitted to the touch chip. After detecting the capacitance change, the touch chip activates the pressure-sensitive chip. The pressure sensor 24 detects external pressure and transmits pressure information to the pressure-sensitive chip, thereby identifying the pressure and activating the button function, thus controlling the working state of the electric toothbrush.

[0042] like Figure 1-8 As shown, the toothbrush main unit 20 also includes a toothbrush top cover 261, a toothbrush bottom cover 262, and a second mounting bracket 27. The toothbrush top cover 261 and the toothbrush bottom cover 262 are respectively mounted on opposite ends of the handle barrel 21. A drive motor 281 electrically connected to the control board 23 is installed between the first mounting bracket 22 and the second mounting bracket 27. The drive shaft of the drive motor 281 passes through the toothbrush top cover 261 and is snapped into the toothbrush head 10. A battery 282 for providing power to the drive motor 281 is installed inside the first mounting bracket 22. In this embodiment, the toothbrush bottom cover 262 is snapped into the handle barrel 21.

[0043] In practice, the control board 23 is fastened to the first mounting bracket 22 with screws, and the first mounting bracket 22 and the second mounting bracket 27 are fastened to each other with screws. When the pressure-sensitive button is triggered, the drive shaft of the drive motor 281 drives the toothbrush head 10 to move, and the toothbrush head 10 can clean the user's teeth, thus realizing electric teeth cleaning.

[0044] like Figure 3 and Figure 5 As shown, a buffer pad 29 is installed on the outer wall of the second mounting bracket 27, which abuts against the inner wall of the handle tube 21. In practice, the buffer section is bonded to the outer wall of the second mounting bracket 27. The buffer pad 29 can buffer and dampen the operation of the drive motor 281, effectively reducing the operating noise of the electric toothbrush and improving the user experience.

[0045] Working principle: Pressing the pressing position 213 by external pressure causes the sensing element 25 to squeeze the pressure sensor 24. The control board 23 recognizes and converts the pressure, realizing the button function. This provides an electric toothbrush with pressure-sensing buttons, eliminating the need for traditional mechanical buttons, preventing dust or moisture from entering the electric toothbrush, and extending the service life of the electric toothbrush.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
