The driving motor 17 is fixedly connected to the casing 11. The worm 18 is fixedly connected to the output rotating shaft of the driving motor 17. A motor slot 16 is provided on the top wall of the cover plate 12, and a part of the driving motor 17 extends into the motor slot 16. The control chip 28 is electrically connected to the driving motor 17. One end of the sensing rod 29 away from the sleeve rod 30 contacts the cabinet door.

[0063] The mounting bracket 34 is fixedly connected to the casing 11. A slot 35 is provided on the mounting bracket 34. The retaining piece 36 is inserted into the slot 35. One end of the worm 18 extends into the slot 35. The retaining piece 36 is installed in the extending direction of the worm 18 and there is a gap between the retaining piece 36 and the end of the worm 18. By providing the retaining piece 36, the axial movement of the worm 18 is reduced.

[0064] Two connecting blocks 13 are provided and are symmetrically and fixedly connected to the side walls of the casing 11. A plurality of jacks 15 are provided and are respectively arranged on the connecting blocks 13. A plurality of connecting holes 14 are provided and are respectively arranged on the connecting blocks 13.

[0065] In order to realize the transmission between the worm 18 and the push rod 27, a transmission member is further provided. The transmission member includes: a first rotating shaft 19, a worm gear 20, a first mating gear 21, a second rotating shaft 22, a driving gear 24, a second mating gear 23, a rack 25, and a guide block 26.

[0066] The first rotating shaft 19 is rotatably connected to the casing 11. The worm gear 20 is fixedly connected to the first rotating shaft 19 and meshes with the worm 18. The first mating gear 21 is fixedly connected to the first rotating shaft 19. The second rotating shaft 22 is rotatably connected to the casing 11. The driving gear 24 is fixedly connected to the second rotating shaft 22. The second mating gear 23 is fixedly connected to the second rotating shaft 22 and meshes with the first mating gear 21. The rack 25 is slidably connected to the inside of the casing 11 and meshes with the driving gear 24. The end wall of the rack 25 is fixedly connected to one end of the push rod 27. The guide block 26 is fixedly connected to the side wall of the rack 25. A guide groove 33 is provided on the bottom wall of the casing 11. The guide block 26 is slidably connected to the guide groove 33.

[0067] Working or installation process:

[0068] When directly knocking on the cabinet door, the cabinet door contacts the end of the induction rod 29 away from the sleeve rod 30, thus transmitting the vibration to the induction rod 29. The induction rod 29 transmits the vibration to the vibration frame 31 through the sleeve rod 30, and transmits the vibration to the vibration sensor in the control chip 28 through the vibration frame 31. The vibration sensor detects the vibration signal and transmits the signal to the control chip 28. The control chip 28 controls the driving motor 17 to start. The output rotating shaft of the driving motor 17 drives the worm 18 to rotate. The worm 18 meshes with the worm gear 20 and drives the worm gear 20 to rotate. The worm gear 20 drives the first rotating shaft 19 to rotate. The first rotating shaft 19 drives the first mating gear 21 to rotate. The first mating gear 21 meshes with the second mating gear 23 and drives the second mating gear 23 to rotate. The second mating gear 23 drives the second rotating shaft 22 to rotate. The second rotating shaft 22 drives the driving gear 24 to rotate. The driving gear 24 meshes with the rack 25 and drives the rack 25 to move. The rack 25 drives the guide block 26 and the push rod 27 to move. Since the guide block 26 is slidably connected to the guide groove 33 and makes the push rod 27 gradually extend out of the casing 11 and push open the cabinet door, the cabinet door rotates and leaves a distance where a palm can be inserted between the cabinet door and the cabinet body. Then, the cabinet door is completely opened by hand;

[0069] After the control chip 28 controls the driving motor 17 to start, after a few seconds of delay, the control chip 28 controls the driving motor 17 to start in the reverse direction. The output rotating shaft of the driving motor 17 drives the worm 18 to rotate in the reverse direction, thereby driving the push rod 27 to slide in the reverse direction and making the push rod 27 no longer press against the cabinet door;

[0070] Among them, in this solution, the vibration sensor in the control chip 28 needs to receive two consecutive vibrations to control the driving motor 17 to start through the control chip 28, that is, it is necessary to double-click the cabinet door to control the driving motor 17 to start through the control chip 28.

[0071] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure with similar functions.
