[0002] As an efficient and convenient teeth cleaning tool, electric toothbrushes are becoming more and more popular in people's daily lives.

[0003] Electric toothbrushes usually use buttons to start, adjust speed, switch modes, and stop. The buttons of electric toothbrushes usually use press-type buttons to operate various commands. However, since the space of an electric toothbrush is small, and it is difficult for the user to adjust the position of the toothbrush handle when using the electric toothbrush to clean teeth, electric toothbrushes usually use a single button to complete the operation of different commands, so that the user only needs to press the button hard to operate various commands without moving his fingers.

[0043] Embodiment 1

[0044] See also Figures 1 to 4 In some embodiments of the present application, an electric toothbrush 10 provided in the present application includes: a housing 11, a circuit board 21, a detection sensor 22 and a pressing member 24.

[0045] The circuit board 21 is installed in the housing 11. The detection sensor 22 is installed on the circuit board 21. The pressing member 24 is conductive, and the pressing member 24 is electrically connected to the circuit board 21.

[0046] When the pressing member 24 is pressed, the pressing member 24 contacts the detection sensor 22 to generate an electrical signal and trigger the detection sensor 22 , thereby forming an effective command to control the operation of the electric toothbrush 10 .

[0047] When using the electric toothbrush 10, the pressing member 24 is pressed. When the pressing member 24 contacts the detection sensor 22, an effective instruction is generated to control the operation of the electric toothbrush 10, which is convenient and quick. If the electric toothbrush 10 is accidentally touched, the pressing member 24 does not contact the detection sensor 22, and an effective instruction cannot be generated, and the electric toothbrush 10 does not work, thereby avoiding misoperation of the electric toothbrush 10 and improving the reliability of the control of the electric toothbrush 10. Only by pressing the pressing member 24 with a certain force and the pressing position is accurate can the detection sensor 22 be touched, so that it is convenient for users to grasp the pressing force and avoid misoperation.

[0048] It is understandable that when the user uses the electric toothbrush 10, the user's finger approaches the pressing member 24, thereby causing the charge in the pressing member 24 to change. The user presses the pressing member 24 with force, thereby causing the pressing member 24 to deform and press against the detection sensor 22. When the pressing member 24 presses against the detection sensor 22, the pressing member 24 and the detection sensor 22 form a conductive circuit loop, thereby causing the changed charge in the pressing member 24 to form a current, thereby generating an electrical signal. When the pressing member 24 presses against the detection sensor 22, the detection sensor 22 can be triggered. In this way, when the pressing member 24 is pressed, an electrical signal can be generated and the detection sensor 22 can be triggered, thereby forming an effective instruction to control the operation of the electric toothbrush 10. Therefore, only by pressing the pressing member 24 with a certain force and the pressing position is accurate can the detection sensor 22 be touched, thereby facilitating the user to grasp the pressing force and avoid misoperation, thereby improving the reliability of the control of the electric toothbrush 10.

[0049] In some embodiments of the present application, the detection sensor 22 includes a pressure sensor 221. The pressing member 24 includes a capacitive sensor. When the pressing member 24 is pressed, the pressing member 24 at least partially abuts against the pressure sensor 221, thereby causing the two stages of the capacitive sensor to be turned on, generating an electrical signal to be fed back to the circuit board 21 to form an effective instruction.

[0050] When the user uses the electric toothbrush 10, the user's finger approaches the pressing member 24, thereby causing the charge in the capacitive sensor to change. The user presses the pressing member 24 hard, thereby causing the pressing member 24 to deform and press against the detection sensor 22. When the pressing member 24 presses against the detection sensor 22, the pressing member 24 and the detection sensor 22 form a conductive circuit loop, thereby causing the changed charge in the pressing member 24 to form a current, thereby generating an electrical signal. When the pressing member 24 presses against the detection sensor 22, the detection sensor 22 is deformed, thereby triggering the pressure sensor 221. In this way, when the pressing member 24 is pressed, an electrical signal can be generated and the detection sensor 22 can be triggered, thereby forming an effective command to control the operation of the electric toothbrush 10. Therefore, only by pressing the pressing member 24 with a certain force and the pressing position is accurate can the detection sensor 22 be touched, thereby facilitating the user to grasp the pressing force and avoid misoperation, thereby improving the reliability of the control of the electric toothbrush 10.

[0051] In some embodiments of the present application, the pressing member 24 includes: a main board portion 243, a connecting portion 244, and a triggering portion 245. The main board portion 243 abuts against the inner wall of the housing 11 and has a gap with the pressure sensor 221. The connecting portion 244 is electrically connected to the circuit board 21. The triggering portion 245 faces the detection sensor 22 and has a gap with the pressure sensor 221. When the pressing member 24 is pressed, the triggering portion 245 abuts against the pressure sensor 221.

[0052] When the user uses the electric toothbrush 10, the user's finger approaches the main board portion 243, thereby forming a capacitive effect between the pressing member 24. When the distance between the user's finger and the main board portion 243 decreases, the charge in the pressing member 24 changes according to the capacitive effect. In addition, there is a gap between the main board portion 243 and the trigger portion 245 and the pressure sensor 221, so the pressing member 24 and the circuit in the circuit board 21 cannot form an effective circuit loop. Pressing the pressing portion causes the trigger portion 245 to abut against the pressure sensor 221, so that the pressing member 24 is connected to the pressure sensor 221 through the trigger portion 245. In addition, the pressing member 24 is electrically connected to the circuit board 21 through the connecting portion 244. Therefore, when the pressing member 24 and the pressure sensor 221 are connected, an effective circuit loop can be formed, so that the charge changed in the pressing member 24 forms a current, thereby generating an electrical signal. When the pressing member 24 presses the detection sensor 22, the detection sensor 22 is deformed, thereby triggering the pressure sensor 221. Thus, when the pressing member 24 is pressed, an electrical signal is generated and the detection sensor 22 is triggered, thereby forming an effective command to control the operation of the electric toothbrush 10. Therefore, only by pressing the pressing member 24 with a certain force and at an accurate pressing position can the detection sensor 22 be touched, thereby facilitating the user to grasp the pressing force and avoid misoperation, thereby improving the reliability of the control of the electric toothbrush 10.

[0053] See also Figure 3 to Figure 4 In some embodiments of the present application, the detection sensor 22 is mounted on the circuit board 21 , and the circuit board 21 is provided with an avoidance groove 213 , and the avoidance groove 213 is located on the inner side of the pressure sensor 221 .

[0054] During the process of pressing the pressing member 24 , the pressure sensor 221 generates strain, and an avoidance groove 213 is opened under the pressure sensor 221 , so that the pressure sensor 221 has enough space to generate deformation, so that the pressure sensor 221 can effectively detect the pressing force data.

[0055] In some embodiments of the present application, the pressing member 24 includes a conductive silicone member 241 .

[0056] The conductive silicone member 241 has a certain structural strength, can undergo elastic deformation, and is conductive. When the pressing member 24 is not pressed, the conductive silicone member 241 has a certain structural strength, so it can effectively avoid triggering the pressure sensor 221. Only when the pressing member 24 is pressed with a certain force can the pressing member 24 produce sufficient deformation to trigger the pressure sensor 221. Because the deformation of the conductive silicone member 241 is elastic deformation, when the pressing member 24 is released, the pressing member 24 returns to the shape before being pressed, and then no longer triggers the pressure sensor 221, so that the process of pressing the pressing member 24 to control the electric toothbrush 10 is reversible. The conductive silicone member 241 is conductive, so it can effectively form a capacitive effect with the user's finger, and the charge inside the conductive silicone member 241 can change when the user's finger is close to the conductive silicone member 241. Since the conductive silicone member 241 is conductive, it can form an effective circuit loop with the circuit in the circuit board 21. In this way, by providing the conductive silicone member 241 , the user can effectively generate an electrical signal when pressing the pressing member 24 , and trigger the pressure sensor 221 , thereby generating an effective command to control the operation of the electric toothbrush 10 .

[0057] In some embodiments of the present application, the circuit board 21 is provided with a soldering pad 211 , and the pressing member 24 is electrically connected to the soldering pad 211 .

[0058] The pad 211 is electrically connected to the internal circuit of the circuit board 21, and the pressing member 24 is electrically connected to the pad 211. When the pressing member 24 is pressed, the electrical signal generated in the pressing member 24 is transmitted to the control system through the pad 211. The control system detects the electrical signal to determine whether the pressing member 24 is effectively pressed.

[0059] In some embodiments of the present application, the pressing member 24 includes a buckling portion 242, the circuit board 21 is provided with a buckling hole 212, and the pad 211 is at least partially located in the buckling hole 212. The buckling portion 242 is inserted into the buckling hole 212 to fix the pressing member 24 and the pad 211 together.

[0060] The buckle part 242 is inserted into the buckle hole 212 of the circuit board 21, and then the buckle part 242 is limited by the inner wall of the buckle hole 212. After the buckle part 242 is inserted into the buckle hole 212, the pressing member 24 is installed on the circuit board 21 to prevent the pressing member 24 and the circuit board 21 from loosening, so that the pressing member 24 is closely attached to the pad 211, and the reliability of the conduction between the pressing member 24 and the pad 211 is improved.

[0061] In some embodiments of the present application, the thickness of the pressing member 24 in the direction from the inner wall of the housing 11 to the circuit board 21 is greater than the distance between the inner wall of the housing 11 and the circuit board 21 when the pressing member 24 is not compressed.

[0062] By making the thickness of the pressing piece 24 in the direction from the inner wall of the shell 11 to the circuit board 21 greater than the distance between the inner wall of the shell 11 and the circuit board 21 when the pressing piece 24 is not compressed, after the pressing piece 24 is installed between the circuit board 21 and the shell 11, the shell 11 presses the pressing piece 24 tightly, so that the pressing piece 24 remains in a compressed state, and the pressing piece 24 can effectively cling to the pad 211 in the circuit board 21, thereby improving the reliability of conduction between the pressing piece 24 and the pad 211.

[0063] In some embodiments of the present application, after the pressing member 24 is installed between the circuit board 21 and the housing 11 , the pressing member 24 is in a compressed state, and the amount of compression of the pressing member 24 is between 0.2 mm and 0.4 mm.

[0064] In some embodiments of the present application, the conductive silicone member 241 is connected to the pad 211 via conductive glue.

[0065] Since the conductive adhesive has both conductivity and adhesion, the conductive silicone member 241 and the pad 211 are adhered together by the conductive adhesive, thereby improving the reliability of the conduction between the conductive silicone member 241 and the pad 211 .

[0066] In some embodiments of the present application, the conductive silicone member 241 is connected to the pad 211 via double-sided tape, and the area of ​​the double-sided tape is smaller than the area of ​​the pad 211 so that the conductive silicone member 241 is exposed from the double-sided tape and in contact with the pad 211 .

[0067] The conductive silicone member 241 is bonded to the pad 211 by double-sided adhesive, so that the relative position between the conductive silicone member 241 and the pad 211 remains stable. By making the area of ​​the double-sided adhesive smaller than the area of ​​the pad 211, so that the double-sided adhesive only covers a part of the pad 211, when the conductive silicone member 241 is close to the pad 211, a part of the conductive silicone member 241 is exposed to the double-sided adhesive, so that a part of the conductive silicone member 241 can contact the pad 211, so that the conductive silicone member 241 and the pad 211 are connected. In this way, the pad 211 and the conductive silicone member 241 are bonded together by double-sided adhesive, and the reliability of the connection between the conductive silicone member 241 and the pad 211 is improved.
