The outer wall of the water receiving pipe 41 is provided with a water receiving port that is connected with the bottom of the filling pipe 410. When the wedge-shaped turntable 432 rotates, since the outer wall of the wedge-shaped turntable 432 is provided with a narrow section and a wide section, in the initial state, the ball 440 is in conflict with the narrow section, and when the wedge-shaped turntable 432 rotates, the ball 440 gradually moves to the wide section.

[0062] Reference Figure 6 As shown, an electrostatic sensor 14 is inserted into the outer wall of the motor 1, and the electrostatic sensor 14 is electrically connected to the controller. When the rotor and stator of the motor 1 rub against each other during operation, the heat generated by the friction will cause electric charge to accumulate on the surface of the motor 1, thereby causing static electricity. The output end of the electrostatic sensor 14 is in contact with the motor 1, and when static electricity generated on the surface is detected, the signal is sent to the controller.

[0063] The working principle of the present invention is as follows: the bottom end of the wire 211 is fixedly connected to the grounder 20. Since the grounder 20 is in contact with the ground, the static electricity on the surface of the motor 1 is introduced into the ground through the grounder 20. When the rotor and stator of the motor 1 rub against each other during operation, the heat generated by the friction will cause electric charge to accumulate on the surface of the motor 1, thereby causing static electricity. The output end of the electrostatic sensor 14 is in contact with the motor 1. When static electricity is detected on the surface, this signal is sent to the controller.

[0064] When the controller receives a signal that static electricity is generated on the surface of the motor 1, the micromotor 320 is started through the controller. Since its output end is fixedly connected to the screw rod 322, the screw rod 322 is rotatably connected to the support frame, the push block 323 is threadedly connected to the screw rod 322, the push block 323 is fixedly connected to one end of the extrusion rod 321, the other end of the extrusion rod 321 is slidably connected to the liquid storage tank 31, one end of the delivery pipe 30 is fixedly connected to the spray hole, and the other end of the delivery pipe 30 is fixedly connected to the liquid storage cotton ball 300 through the sealing cover 200, so that the conductive solution stored in the liquid storage tank 31 is delivered to the liquid storage cotton ball 300, and is slowly released from the grounding device 20 through several through holes. The conductive solution adhered to the outer wall of the grounding device 20 enhances the conductive performance of the grounding device 20, thereby effectively improving the static electricity release efficiency and effect of the motor 1.

[0065] When the push block 323 drives the extrusion rod 321 to squeeze the conductive solution box liquid storage cotton ball 300 in the liquid storage tank 31 toward one end of the delivery tube 30, one end of the pull rope 421 is fixedly connected to the push block 323 through the traction block 420, and the other end of the pull rope 421 is fixedly connected to one end of the rack 422. The other end of the rack 422 and the inner wall of the guide rail are respectively fixedly connected to the two ends of the first return spring 423. In the initial state, the first return spring 423 is in a stretched state and the pull rope 421 is in a stretched state. When the push block 323 approaches one end of the rack 422, the pull rope 421 is temporarily relaxed, so that the end of the rack 422 away from the first return spring 423 is no longer tightened by the pull rope 421. When the first return spring 423 changes from a stretched state to a contracted state, the rack 422 is driven to slide in the guide rail toward one end close to the first return spring 423, and the pull rope 421 quickly returns to a stretched state, and the two groove wheels 13 play a limiting role.

[0066] When the rack 422 slides inside the guide rail toward the end away from the pull rope 421, due to the rotational connection between the rotating shaft 430 and the U-shaped rod, the rack 422 is meshed with the gear 431, and the gear 431 and the wedge-shaped turntable 432 are respectively fixedly connected to the two ends of the rotating shaft 430, thereby driving the wedge-shaped turntable 432 to rotate.

[0067] When the wedge-shaped turntable 432 rotates, since the outer wall of the wedge-shaped turntable 432 is provided with a narrow section and a wide section, in the initial state, the ball 440 contacts the narrow section, and when the wedge-shaped turntable 432 rotates, the ball 440 gradually contacts the wide section, so that the wide section touches the ball 440. Since the ball 440 is rotatably connected to the flange 445, the flange 445 and the push plate 442 are respectively fixedly connected to the two ends of the slide bar 441, and the slide bar 441 is slidably connected to the water receiving pipe 41, the push plate 442 is driven to slide inside the water receiving pipe 41 toward the end away from the wedge-shaped turntable 432, thereby the previously dropped The water in the water receiving pipe 41 is squeezed toward the water delivery pipe 450. During this process, the arc baffle 443 gradually approaches the water receiving port until it is blocked. Each time the slide rod 441 drives the push plate 442 to reset, the arc baffle 443 moves away from under the water receiving port, making it convenient for the water in the water storage tank 40 to automatically pass through the filling pipe 410 and fall into the water receiving pipe 41, making it convenient to squeeze water toward the water delivery pipe 450 next time, and having an automatic water supply function. The second reset spring 444 drives the slide rod 441 to automatically reset each time the wedge-shaped turntable 432 resets to its initial state, making it convenient to squeeze the push plate 442 next time.

[0068] When water is squeezed into the water supply pipe 450 from the water receiving pipe 41, since the connecting pipe 451 is fixedly connected to the two branch pipes 452, one of the branch pipes 452 close to the water storage tank 40 and the water spray port are respectively fixedly connected to the two ends of the water supply pipe 450, and every two atomizing nozzles 46 are fixedly connected to the two ends of a branch pipe 452, and then the water is sprayed around the motor 1 in four directions through the four atomizing nozzles 46 to increase the air humidity around the motor 1 to prevent static electricity from being generated again due to drying.

[0069] Since the sealing cover 200 is threadedly connected to the tank body 201, the grounding device 20 can be opened. After the sealing cover 200 is opened, the liquid storage cotton ball 300 inside the tank body 201 can be taken out, so that the liquid storage cotton ball 300 can be replaced.
