[0019] A liquid storage cylinder 9 is arranged inside the top mounting member 8, a starting motor 15 is fixedly connected to the inner wall of the top mounting member 8, a main lead screw 16 is arranged at the output end of the starting motor 15, and an insect-proof cleaning mechanism is arranged on the main lead screw 16.

[0020] The insect-proof cleaning mechanism includes a driving wheel 17 sleeved on the outer wall of the main screw 16, and a plurality of auxiliary arms 18 are fixedly connected to the outer wall of the driving wheel 17. A plurality of outer tubes 21 are arranged on the outside of the top mounting member 8, and the plurality of outer tubes 21 all penetrate into the interior of the top mounting member 8. A bracket 19 is arranged at the open ends of the plurality of outer tubes 21, and a reciprocating screw 10 is rotatably connected to the bracket 19. A fan 20 is fixedly connected to the lower end of the reciprocating screw 10, and a drip hole 42 is arranged at the bottom of the fan 20. The ends of the plurality of auxiliary arms 18 away from the driving wheel 17 are respectively threadedly sleeved on the corresponding reciprocating screws 10. The reciprocating screw 10 is hollow, and the upper end of the reciprocating screw 10 is rotatably connected to the interior of the liquid storage cylinder 9.

When the auxiliary arms 18 reciprocate up and down on the reciprocating screw 10, it will drive the reciprocating screw 10 and the fan 20 at its end to rotate and blow air into the outer tube 21, and then pass through the outer tube 2 1 is transported, and the air is blown to the surface of the luminous lampshade 39 by the air blowing parts 35. By blowing air around the luminous lampshade 39 by multiple air blowing parts 35, mosquitoes attached to the luminous lampshade 39 can be driven away, thereby ensuring the lighting effect of the luminous lampshade 39, and when the outer tube 21 blows air, a part of the wind will be blown to the high ceiling lamp body 32 where the heat is more serious through the multiple air blowing holes 40, so as to blow air to cool the high ceiling lamp body 32, thereby ensuring the use effect of the high ceiling lamp body 32 and reducing the attraction of the entire high ceiling lamp body 32 to heat-seeking mosquitoes.

[0024] Example 2: Please refer to Figure 1 - Fig.10 The upper end of the reciprocating screw 10 is connected to a top wheel 11, and a plurality of telescopic tubes 12 are slidably connected to the inner wall of the top wheel 11. Pressure springs 13 are sleeved on the outer walls of the plurality of telescopic tubes 12, and one end of the pressure spring 13 is in contact with the inner wall of the top wheel 11. Flow holes 14 are provided on the plurality of telescopic tubes 12, and the ends of the plurality of telescopic tubes 12 away from the inside of the top wheel 11 are sealed.

[0025] A plurality of air ejection holes 40 are provided on the outer walls of the plurality of outer tubes 21, a sleeve 31 is slidably connected to the outer walls of the plurality of outer tubes 21, a support member 41 is provided on the outer wall of the sleeve 31, the support member 41 slides through the interior of the top mounting member 8, an outer ring 22 is fixedly connected to the end of the support member 41, a telescopic spring 43 is fixedly connected to the outer wall of the outer ring 22, the other end of the telescopic spring 43 is fixedly connected to the inner wall of the top mounting member 8, and an inner magnetic ring 23 is provided on the outer ring 22.

[0026] Both sides of the bottom of the main screw 16 are fixedly connected with slide rails 28, and the inner wall of the slide rail 28 is slidably connected with a contact magnet 29. A tension spring 30 is provided at the tail of the contact magnet 29. The end of the tension spring 30 away from the contact magnet 29 is fixedly connected to the inner wall of the slide rail 28, and the magnetic pole of the contact magnet 29 is the same as the magnetic pole of the inner magnetic ring 23.

[0027] A luminous lampshade 39 is arranged on the outer protective lampshade 33, sliding grooves are provided on both sides of the luminous lampshade 39, scrapers 36 are slidably connected on both sides of the sliding grooves, return springs 38 are fixedly connected on both sides of the scraper 36, and a plurality of side magnets 37 are arranged on the outer wall of the scraper 36, and the side magnets 37 have the same magnetic poles as the pushing magnet 34, and an air spray part 35 is connected to the end of the outer tube 21 away from the sleeve 31.

[0028] In this embodiment, as the use time increases, when dust is found to be attached to the light-emitting lampshade 39 and needs to be cleaned, the operator can increase the power of the starting motor 15 to drive the main screw 16 to rotate rapidly. When the main screw 16 rotates rapidly, the auxiliary arm 18 is driven by the driving wheel 17 to move up and down on the reciprocating screw 10 at a high frequency. When the auxiliary arm 18 moves up and down on the reciprocating screw 10 at a high frequency, the reciprocating screw 10 drives the fan 20 to rotate rapidly. When the fan When the top wheel 11 rotates rapidly, the top wheel 11 in the liquid storage cylinder 9 will be driven to rotate rapidly. When the top wheel 11 rotates rapidly, under the action of a large centrifugal force, the multiple telescopic tubes 12 will be thrown to the outside of the top wheel 11, so that the flow holes 14 originally located in the top wheel 11 are exposed outside the top wheel 11. When the flow holes 14 are exposed outside the top wheel 11, the cleaning liquid in the liquid storage cylinder 9 will enter the top wheel 11 through the exposed flow holes 14, and then enter the fan 20 through the hollow reciprocating screw 10, and the cleaning liquid in the liquid storage cylinder 9 will enter the top wheel 11 through the exposed flow holes 14, and then enter the fan 20 through the hollow reciprocating screw 10, and the cleaning liquid in the liquid storage cylinder 9 will enter the top wheel 11 through the exposed flow holes 14. The drip holes 42 on the fan 20 drip into the outer tube 21, and the wind blown by the rapidly rotating fan 20 finally allows the air spraying member 35 to spray the cleaning liquid onto the surface of the light-emitting lampshade 39. When the main lead screw 16 rotates, it will drive the slide rail 28 at its bottom to rotate synchronously. Under the centrifugal force generated by the rapid rotation, the contact magnet 29 will overcome the pulling force of the tension spring 30 and move to the outside of the slide rail 28. When the contact magnet 29 moves to the outside of the slide rail 28, it will be just above the inner magnetic ring 23. At this time, Under the action of the repulsive magnetic force between the two, the outer ring 22 and the inner magnetic ring 23 will overcome the elastic force of the telescopic spring 43, pushing the support member 41 to move toward the outside of the top mounting member 8. When the support member 41 moves toward the outside of the top mounting member 8, it will push the sleeve 31 to move downward synchronously to block the multiple air holes 40. When the multiple air holes 40 are blocked, without the side-blowing wind diversion of the multiple air holes 40, the wind force of the fan 20 blowing toward the air spray member 35 containing the cleaning liquid will be stronger, thereby improving the carrying capacity of the cleaning liquid.

[0029] When the contact magnet 29 is thrown to the outside of the slide rail 28, as the main screw 16 rotates and presses the inner magnetic ring 23, the contact magnet 29 will be intermittently located above the trigger magnet 27. Under the combined action of the intermittent magnetic force of the trigger magnet 27 and the contact magnet 29 and the elastic force of the return spring 25, the pressure plate 26 will press the side plate 24 to move up and down. When the side plate 24 moves up and down, the pushing magnet 34 will be intermittently located on the side of the side magnet 37. Under the action of the intermittent repulsive magnetic force between the two and the elastic force of the return spring 38, the scraper 36 will scrape back and forth on the luminous lampshade 39, and cooperate with the cleaning liquid sprayed by the air spray part 35 to scrape and clean the dirt on the luminous lampshade 39 to ensure the lighting effect of the luminous lampshade 39.

[0030] It should be noted that a ventilation hole is provided on the rear side of the top mounting member 8, which is not marked in the drawing due to the display angle.

[0031] It should be noted that, refer to Fig. 9 The opening of the dripping hole 42 is relatively small, and the cleaning liquid dripping through the dripping hole 42 is relatively small droplets, which can be sprayed along with the wind blown by the fan 20.
