These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0017] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 5 As shown, this embodiment provides a toothbrush with built-in buttons, including a handle portion 10 and a brush head portion 20. The handle portion 10 includes a handle shell 11, a control circuit board 12, a fixed end piece 13, a shaft 14, and a pressing member 16. The control circuit board 12 is assembled inside the handle shell 11, and a function button 121 is respectively provided on both sides of its front end (e.g., left and right sides); specifically, the function button 121 located on the left side is defined as the left button, and the function button 121 located on the right side is defined as the right button. The fixed end piece 13 is fixed to the front end of the handle shell 11, specifically fixed in the opening at the front end of the handle shell 11. The shaft 14 is hinged to the fixed end piece 13, and the movable gap between the shaft 14 and the fixed end piece 13 is filled with an elastic buffer 15. The setting of the elastic buffer 15 makes the shaft 14 not swing arbitrarily. Only when the shaft 14 is subjected to a certain degree of external force will the shaft 14 squeeze the elastic buffer 15 and produce a certain displacement swing.

[0020] The front end of the shaft 14 extends out of the brush handle housing 11 and is connected to the brush head portion 20. Specifically, the front end of the shaft 14 is detachably inserted into the brush head portion 20. Furthermore, to prevent the brush head portion 20 from being installed backwards, both the front end of the brush handle housing 11 and the brush head portion 20 are provided with inclined end faces. Only when the brush head portion 20 is installed in the correct orientation can the front end of the brush handle housing 11 and the brush head portion 20 be connected. If installed in the opposite direction, they cannot be connected.

[0021] The rear end of the shaft 14 is connected to the pressing member 16. The pressing member 16 has two pressing heads 161 spaced apart. The front end of the control circuit board 12 is located between the two pressing heads 161, and the two pressing heads 161 correspond to the function buttons 121 on both sides of the control circuit board 12. For example, the pressing head 161 on the left corresponds to the left button, and the pressing head 161 on the right corresponds to the right button. Specifically, in a natural state without external force applied, the pressing heads 161 and the corresponding function buttons 121 are spaced apart.

[0022] One application of this toothbrush is as follows: of the two built-in function buttons 121, one button can be used as the power switch, and the other button can be used for pressure monitoring. Specifically, the button on the same side as the bristles of the brush head 20 (such as the left button) is used as the power switch; the other side (such as the right button) is used for pressure monitoring. Before use, the brush head 20 is turned to the left in the direction of the bristles, causing the shaft 14 to swing and the pressing member 16 to swing to the right. At this time, the pressing head 161 on the left side of the pressing member 16 presses the left button to turn on the toothbrush. When the user brushes their teeth, if the pressure applied during brushing is too great, the teeth exert a reaction force on the brush head 20, causing the brush head 20 to bend away from the direction of the bristles (to the right), thereby causing the pressing member 16 to swing to the left. At this time, the pressing head 161 on the right side of the pressing member 16 presses the right button, thereby triggering the right button, indicating that the force applied during brushing is greater than the preset value. The control circuit board 12 outputs information for user reference to help them correct their brushing technique. After brushing, the brush head 20 can be turned off by moving it to the left.

[0023] Specifically, the above is one application. Of course, based on the structure of this embodiment, other applications can be extended through the control of existing programs. For example, by moving the brush head part 20 in a certain order, the left and right buttons can be pressed in a certain order to unlock other preset functions. This is something that those skilled in the art have long known, and will not be described in detail here.

[0024] Specifically, the information output by the control circuit board 12 is existing technology. For example, the control circuit board 12 is equipped with a wireless communication module, such as a WiFi communication module, and communicates with a remote end (such as a mobile phone) through the wireless communication module to transmit information to the remote end.

[0025] The system also includes an indicator light 181, and the control circuit board 12 is connected to the indicator light 181 to control its operation. For example, when the power switch is turned on, the control circuit board 12 causes the indicator light 181 to emit light, such as white light; when the pressure monitoring function button 121 is pressed during use, the control circuit board 12 causes the indicator light 181 to emit light of other colors, such as red light, to promptly alert the user. The technology of the control circuit board 12 controlling the indicator light 181 to emit light is prior art and will not be described in detail here.

[0026] Furthermore, the indicator light 181 is a ring light, the indicator light 1851 is sleeved on the front end of the fixed end piece 13, and a light-transmitting sealing gasket 182 is provided between the brush handle housing 11 and the brush head part 20. The light emitted by the indicator light 181 is emitted through the sealing gasket 182; it serves both as an effective reminder and as an aesthetic effect.

[0027] Of course, in other embodiments, only the structure of the wireless communication module or the indicator light 181 can be used to interact with the outside world.

[0028] The fixed end member 13 is provided with a through hole that extends from front to back. The shaft 14 passes through the through hole of the fixed end member 13. The elastic buffer member 15 is a buffer bushing. The buffer bushing is sleeved on the shaft 14 and fills the through hole of the fixed end member 13; it also plays a good sealing role.

[0029] A fixing bracket 17 is fixed inside the brush handle housing 11, and the control circuit board 12 is fixed on the fixing bracket 17. In this embodiment, the fixing bracket 17 is provided with snap-fit ​​connectors 171 on both sides, and the control circuit board 12 is provided with snap-fit ​​slots 122. The snap-fit ​​connectors 171 on both sides are fixedly snapped into the snap-fit ​​slots 122 of the control circuit board 12 to achieve fixation.

[0030] Furthermore, the fixed bracket 17 is provided with an abutment limiting groove 172, and the front end of the control circuit board 12 abuts against the abutment limiting groove 172 to achieve positioning and assembly; at the same time, the front end of the fixed bracket 17 abuts against the fixed end piece 13 to achieve positioning and assembly of the control circuit board 12, the fixed end piece 13, the shaft 14 and the pressing piece 16, so that the pressing piece 16 and the function button 121 are accurately positioned.

[0031] The side end of the pressing member 16 is also provided with a limiting groove 162, and the fixed bracket 17 is provided with a limiting protrusion 173. The size of the limiting protrusion 173 is smaller than the limiting groove 162 and is inserted into the limiting groove 162; so as to limit the swing range of the shaft 14 and further improve the alignment accuracy.

[0032] The pressing head 161 of the pressing member 16 has a pressing protrusion protruding towards the function button 121, and the function button 121 is pressed through the protruding pressing protrusion without being obstructed by other structures.

[0033] Furthermore, the fixed bracket 17 is also provided with a battery 19, specifically a wirelessly rechargeable battery, which supplies power to electrical components such as the control circuit board 12 and indicator lights 181.

[0034] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
