[0028] The present invention is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, the push switch structure includes a silicone outer shell 1 and a plastic inner shell 2, wherein the silicone outer shell 1 is nested in the plastic inner shell 2, and the plastic inner shell 2 includes a first inner shell 21 and a second inner shell 22 spliced ​​together, and a circuit board 23 is installed between the first inner shell 21 and the second inner shell 22, and the circuit board 23 is installed with a driving switch 26. The silicone outer shell 1 is molded with a surface switch 11, and the surface switch 11 is recessed in the surface of the silicone outer shell 1, and the surface switch 11 is in contact with the driving switch 26; by pressing the surface switch 11 to contact the driving switch 26, the device is controlled. Since the surface switch 11 is recessed in the surface of the silicone outer shell 1, there will be no accidental touch after contact. The concave surface switch 11 needs to be pressed to control it, which prevents pauses or mode changes due to accidental touches during use, thereby increasing the comfort of use.

[0030] The driving switch 26 is a pressure-pressing switch; the pressure-pressing switch can send different pulse signals to the circuit board 23 according to the pressing force, and the circuit board 23 can make different instructions according to the different pulse signals received.

[0031] In one embodiment, a vibration motor is installed in the plastic inner shell 2, and the vibration motor is connected to the circuit board 23 for signal connection. The plastic inner shell 2 is also provided with a battery to power the circuit board 23 and the vibration motor. Engineers program the circuit board 23. When driving the switch 26, the greater the pressure, the greater the vibration amplitude of the vibration motor, and vice versa, the smaller the pressure, the smaller the vibration amplitude.

[0032] Preferably, a circuit cavity 17 for installing a circuit board 23 is formed in the first inner shell 21 and the second inner shell 22 respectively. The vibration motor, the circuit board 23, etc. are all installed in the circuit cavity 17 to fix them in place and prevent them from shifting.

[0033] A switch slot for installing the drive switch 26 is provided between the first inner shell 21 and the second inner shell 22. The switch slot is aligned with the surface switch 11. The drive switch 26 can be installed and positioned through the switch slot. After being installed in the switch slot, the drive switch 26 can be stably installed in place, so that the surface switch 11 can remain aligned with the drive switch 26. When the surface switch 11 is pressed, it can accurately contact the surface switch 11.

[0034] Furthermore, the switch slot includes a first half slot 24 formed in the first inner shell 21 and a second half slot 25 formed in the second inner shell 22. After the first inner shell 21 and the second inner shell 22 are spliced ​​together, the first half slot 24 and the second half slot 25 are spliced ​​together to form a switch slot for installing the drive switch 26.

[0035] The driving switch 26 includes a sensing portion 27 that contacts the surface switch 11 and a conductive portion 28 that contacts the circuit board 23. The conductive portion 28 is perpendicular to the sensing portion 27 and is installed in the switch slot. The conductive portion 28 extends toward the circuit board 23. Since the switch slot is spliced ​​by the first inner shell 21 and the second inner shell 22, the spliced ​​switch slot just positions the shell for the driving switch 26. The sensing portion 27 of the driving switch 26 is positioned in the switch slot and can contact and cooperate with the surface switch 11. The conductive portion 28 of the driving switch 26 passes through the gap and is connected to the circuit board 23 of the circuit cavity 17 to realize signal transmission.

[0036] The silicone outer shell 1 and the plastic inner shell 2 are both columnar structures, providing a better grip.

[0037] Furthermore, a charging structure is provided between the silicone outer shell 1 and the plastic inner shell 2. The charging structure includes a charging socket 14 installed on the circuit board 23. The battery is installed on the circuit board 23. The charging socket 14 is installed with a pair of positive and negative charging probes 15. The battery can be charged through the charging probes 15 to realize power supply.

[0038] Furthermore, the silicone shell 1 is formed with a charging port 16 for exposing the end of the charging probe 15 .

[0039] Furthermore, a raised positioning bump 12 is formed inside the silicone shell 1, and a positioning groove 13 is formed inside the plastic inner shell 2 to cooperate with the positioning bump 12. After the silicone shell 1 is nested in the plastic inner shell 2, the positioning bump 12 cooperates with the positioning groove 13 to prevent the silicone shell 1 from shifting.

[0040] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
