Description

Technical Field

[0001] This invention belongs to the field of LED lighting technology, specifically an LED lighting fixture for garden roads. Background Technology

[0002] LED lights are a novel light source that has emerged rapidly in recent years. They are the fourth generation of new light sources after incandescent lamps, fluorescent lamps, and high-intensity discharge lamps. Solid-state lighting based on white LEDs is a typical green lighting method. Compared with traditional light sources, they have many advantages such as energy saving, environmental protection, long lifespan, small size, safety and reliability, and fast response speed. They represent the future of lighting technology and are currently widely used in urban landscape decoration, traffic signals, commercial advertising, and home lighting.

[0003] Existing technologies also include some technical solutions for LED lighting fixtures. For example, a Chinese patent with application number 2017100344169 discloses an LED lighting fixture for municipal roads, including a power supply lamp holder and a lighting lamp for connecting and cooperating with the power supply lamp holder. The power supply lamp holder has a first sliding groove in the middle of its interior, a second sliding groove below the bottom of the first sliding groove, a power supply groove on the top wall of the power supply lamp holder above the top of the first sliding groove, a first guide groove on the inner side wall of the power supply lamp holder on both sides of the first sliding groove, a top-pressing slider slidably connected in the first guide groove, a conductive post on the top of the top-pressing slider opposite to the power supply groove, a first spring on the top of the top-pressing slider in the first guide groove, a conical groove between the first and second sliding grooves, and locking holes symmetrically provided in the power supply lamp holder on both sides of the second sliding groove. A second guide groove is provided on the side of the locking hole closest to the second sliding groove. This invention has a simple structure, is easy to install, has high stability after installation, and improves safety by preventing accidental electric shock.

[0004] Currently, some garden paths are equipped with LED lights. Because the lampshades of LED lights need to have heat dissipation holes, a large number of insects will enter the lampshades and be killed by the high temperature. Over time, the excessive accumulation of insect corpses in the lampshades will affect the overall aesthetics of the garden lights.

[0005] Therefore, the present invention provides an LED lighting fixture for garden roads. Summary of the Invention

[0006] To address the shortcomings of existing technologies and solve the problem that LED lights installed on some garden paths require heat dissipation holes, which can lead to a large number of insects entering the lampshade and being killed by the high temperature. Over time, the excessive accumulation of insect corpses in the lampshade can affect the overall aesthetics of the garden lights. Therefore, this invention proposes an LED light fixture for garden paths.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: An LED lighting fixture for garden roads, comprising a lamp holder; a pair of lamp covers mounted on the top of the lamp holder; LED lights installed in the lamp covers; a light-transmitting plate hinged to the bottom of the lamp covers; a mounting housing fixedly connected to the lamp holder near the lamp covers, and a dual-head motor installed in the mounting housing; a drive shaft fixedly connected to the output shaft of the dual-head motor; a reel fixedly connected to one end of the drive shaft extending into the lamp covers; a pull rope fixedly connected to and wound around the reel, and the other end of the pull rope... The end is fixed to the light-transmitting panel; after the lamp has been used for a long time, many insect corpses are easily left inside the lampshade. By periodically starting the dual-head motor, the drive shaft is driven to rotate, which in turn drives the roller to rotate, loosening the No. 1 pull rope wrapped on the roller. Then, the light-transmitting panel naturally rotates and hangs down under its own weight, and the insect corpses on the upper side of the light-transmitting panel naturally slide off, achieving the effect of cleaning the inside of the lampshade. This avoids the problem of too many insects inside the lampshade affecting the aesthetics of the lamp. After cleaning, the dual-head motor drives the drive shaft to reverse and pull the light-transmitting panel to a horizontal position.

[0008] Preferably, the drive shaft includes a solid shaft and a hollow shaft, with the solid shaft slidably connected to the hollow shaft via a groove, and the hollow shaft fixedly connected to the roller; the hollow shaft is connected to the lampshade via a screw and nut pair; an airbag is fixedly connected to the inner wall of the lampshade near the roller; a pair of piston tubes are fixedly connected to the lampshade on both sides of the LED lamp, and the piston tubes communicate with the airbags via conduits; a piston rod is slidably connected to the piston tube; an elastic strip is fixedly connected between the upper end of the piston rod and the lampshade, and a cleaning ring is fixedly connected to the lower end of the piston rod, with the LED lamp passing through the cleaning ring; the cleaning... The inner side of the ring is equipped with a sponge; when the dual-head motor drives the solid shaft and the hollow shaft to rotate, the hollow shaft is connected to the lampshade through a screw and nut pair, causing the roller to move towards the inner wall of the lampshade and squeeze the air bag. Then, the gas in the air bag enters the piston tube through the conduit, pushing the piston rod to move downward, which in turn drives the cleaning ring to move downward as well. The sponge on the inner side of the cleaning ring slides and rubs against the surface of the LED light, thereby cleaning the LED light and preventing insects from entering the lampshade and hitting the LED light, leaving body fluids on the surface of the LED light, which would cause the problem of light spots when the LED light is lit.

[0009] Preferably, an elastic membrane is fixedly attached to the inner side of the cleaning ring; the sponge is fixedly attached to the side of the elastic membrane near the LED light; an elastic block is fixedly attached between the elastic membrane and the inner side of the cleaning ring; by setting the elastic membrane and the elastic block, during the process of the sponge sliding and rubbing against the LED light surface, the elastic block can always press the sponge tightly against the LED light surface, improving the adhesion between the sponge and the LED light surface, thereby adapting to LED lights of different shapes, improving the cleaning effect of the sponge on the LED light, and increasing the cleanable area.

[0010] Preferably, a C-shaped frame is fixedly connected to the lower end of the piston tube; a second pull rope is fixedly connected between the inner side of the elastic membrane and the bottom end of the C-shaped frame; the second pull rope passes through the elastic block, the cleaning ring, and the piston rod, and the second pull rope is slidably connected to the elastic block, the cleaning ring, and the piston rod; when the piston rod moves downward, the second pull rope is relaxed, and the elastic block can press the sponge onto the surface of the LED lamp and clean it; when the elastic strip pulls the piston rod upward to reset, the second pull rope is gradually tightened, so that after the cleaning ring resets to its limit position, the second pull rope pulls the elastic membrane and moves the sponge away from the surface of the LED lamp, avoiding the problem of poor heat dissipation when the LED lamp is working normally.

[0011] Preferably, the lamp holder is a hollow structure; a receiving dish is provided below the lampshade, and the receiving dish is fixedly connected to and communicates with the lamp holder; a trash can is installed at the bottom of the lamp holder, and the lamp holder and the trash can are connected by an inclined tube; a filter screen is fixedly connected to the lamp holder near the inclined tube; by setting up the trash can, the functionality of the lamp can be improved, and when the light-transmitting plate rotates and hangs down, the insect corpses on the upper side of the light-transmitting plate can slide into the receiving dish, and finally enter the trash can through the lamp holder and the inclined tube, avoiding the problem of the light-transmitting plate directly scattering insects on the ground, affecting the aesthetics of the garden path, and avoiding the tedious operation of cleaning workers cleaning each section individually.

[0012] Preferably, an expansion water-stop strip is fixedly connected to the inclined tube, and the expansion water-stop strip is made of water-absorbing material. On rainy days, rainwater enters the lamp holder through the receiving dish, washing the inner wall of the receiving dish and the lamp holder, which can prevent insect body fluids from flowing out and adhering to the inner wall or filter screen, causing blockage. At the same time, the expansion water-stop strip expands rapidly when it comes into contact with water and seals the inclined tube, preventing a large amount of rainwater from entering the trash can and causing the trash to deteriorate. When the expansion water-stop strip dries and shrinks, the inclined hole is no longer sealed, and the insects accumulated on the upper side of the filter screen will naturally slide into the trash can.

[0013] Preferably, a rotating shaft is rotatably connected to the lamp holder below the filter screen via a bracket; an auger is fixedly connected to the outside of the rotating shaft; a pair of swing bars are fixedly connected to one end of the rotating shaft extending to the upper part of the filter screen, and the rotating shaft is rotatably connected to the filter screen; when rainwater flows downward inside the lamp holder, it will push the auger to rotate, and then the auger will drive the rotating shaft and swing bars to rotate. The swing bars scrape the surface of the filter screen, thereby peeling off the insects adhering to the surface of the filter screen. When the expansion sealing strip dries and shrinks, the oblique hole is no longer sealed, and the insect corpses accumulated on the upper part of the filter screen will naturally slide into the trash can.

[0014] Preferably, several No. 1 springs are fixedly connected to the inner wall of the lamp holder near the auger; a small ball is fixedly connected to the free end of each No. 1 spring; by setting the No. 1 spring and the small ball, when the water flow drives the auger to rotate, the auger will intermittently poke the small ball and deform the No. 1 spring. When the auger separates from the small ball, the small ball swings back under the action of the No. 1 spring and hits the inner wall of the lamp holder, causing the lamp holder and the filter screen to vibrate. Accompanied by the scraping effect of the swing bar, the separation efficiency between insects and the filter screen is further improved.

[0015] Preferably, a plurality of No. 1 magnets are evenly arranged around the circumference of the reel; a plurality of No. 2 magnets are evenly arranged at intervals inside the No. 1 pull rope; when the No. 1 pull rope is wound around the reel, the No. 1 magnets and No. 2 magnets are close to each other, and the magnetic poles of the No. 1 magnets and No. 2 magnets are opposite at the positions where they are close to each other; as the reel rotates and the No. 1 pull rope is released, the No. 1 pull rope is tightly attached to the surface of the reel due to the mutual attraction between the No. 1 magnets and No. 2 magnets. When the tension on the No. 1 pull rope is greater than the attraction between the No. 1 magnets and No. 2 magnets, the No. 1 pull rope will quickly detach from the reel, and then the No. 1 pull rope will cause the light-transmitting plate to shake slightly, shaking off the insects on the upper side of the light-transmitting plate, thus improving the cleaning effect.

[0016] Preferably, the roller has several evenly spaced sliding holes around its circumference, and a first magnet is slidably connected in one of these holes. A second spring is fixedly connected between the outer end of the sliding hole and the first magnet. As the roller rotates and the first pull rope is released, the first magnet and the second magnet attract each other, causing the first magnet to move toward the first pull rope and compress the second spring. When the first pull rope quickly disengages from the roller, the first magnet, under the thrust of the second spring, strikes the inner end of the sliding hole, causing the roller and the first pull rope to shake, further shaking off the insects on the upper side of the light-transmitting plate and improving the cleaning effect.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention relates to an LED light fixture for garden roads. After prolonged use, the lampshade is prone to accumulating insect carcasses. By periodically activating a dual-head motor, the drive shaft rotates, which in turn drives a roller to rotate. This loosens the No. 1 pull rope wound on the roller, allowing the light-transmitting panel to naturally rotate and droop under its own weight. The insect carcasses on the upper side of the light-transmitting panel naturally slide off, achieving the effect of cleaning the inside of the lampshade. This avoids the problem of excessive insects inside the lampshade affecting the aesthetics of the light fixture. After cleaning, the dual-head motor drives the drive shaft to reverse, pulling the light-transmitting panel to a horizontal position.

[0019] 2. The LED lighting fixture for garden roads described in this invention, when driven by a dual-head motor to rotate a solid shaft and a hollow shaft, is connected to the lampshade via a screw and nut pair. This causes the roller to move towards the inner wall of the lampshade and compress the air bladder. The gas in the air bladder then enters the piston tube through a conduit, pushing the piston rod downwards. This, in turn, causes the cleaning ring to move downwards as well. The sponge on the inner side of the cleaning ring slides and rubs against the surface of the LED light, thereby cleaning the LED light and preventing insects from entering the lampshade and impacting the LED light, leaving body fluids on the LED light surface, which would cause light spots when the LED light is emitting light.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figures 1 to 5As shown, the present invention discloses an LED light fixture for garden roads, comprising a light frame 1; a pair of lampshades 2 are mounted on the top of the light frame 1; LED lights 3 are installed in the lampshades 2; a light-transmitting plate 4 is hinged to the bottom of the lampshades 2; a mounting housing 5 is fixedly connected to the light frame 1 near the lampshades 2, and a dual-head motor is installed in the mounting housing 5; a drive shaft is fixedly connected to the output shaft of the dual-head motor; a reel 6 is fixedly connected to one end of the drive shaft extending into the lampshades 2; a pull rope 7 is fixedly connected to and wound around the reel 6, and the other end of the pull rope 7 is connected to the light-transmitting plate. 4. Fixing: After prolonged use, the lampshade 2 may accumulate a lot of insect corpses. By periodically starting the dual-head motor, the drive shaft rotates, which in turn drives the roller 6 to rotate. This loosens the No. 1 pull rope 7 wrapped around the roller 6, allowing the light-transmitting plate 4 to naturally rotate and droop under its own weight. The insect corpses on the upper side of the light-transmitting plate 4 naturally slide off, achieving the effect of cleaning the inside of the lampshade 2. This avoids the problem of too many insects inside the lampshade 2 affecting the aesthetics of the lamp. After cleaning, the dual-head motor drives the drive shaft to reverse, pulling the light-transmitting plate 4 to a horizontal position.

[0031] The drive shaft includes a solid shaft 8 and a hollow shaft 9, with the solid shaft 8 slidably connected to the hollow shaft 9 via a groove. The hollow shaft 9 is fixedly connected to the roller 6. The hollow shaft 9 is connected to the lampshade 2 via a screw and nut assembly. An airbag 10 is fixedly connected to the inner wall of the lampshade 2 near the roller 6. A pair of piston tubes 11 are fixedly connected to the lampshade 2 on both sides of the LED lamp 3, and the piston tubes 11 are connected to the airbags 10 via conduits. A piston rod 12 is slidably connected to the piston tube 11. An elastic strip 13 is fixedly connected between the upper end of the piston rod 12 and the lampshade 2, and a cleaning ring 14 is fixedly connected to the lower end of the piston rod 12, with the LED lamp 3 passing through the cleaning ring 14. The inner side of the cleaning ring 14 is provided with a sponge 15. When the double-headed motor drives the solid shaft 8 and the hollow shaft 9 to rotate, the hollow shaft 9 is connected to the lamp cover 2 through a screw and nut pair, which causes the roller 6 to move toward the inner wall of the lamp cover 2 and squeeze the air bag 10. Then the gas in the air bag 10 enters the piston tube 11 through the conduit, pushing the piston rod 12 to move downward, which in turn drives the cleaning ring 14 to move downward as well. The sponge 15 on the inner side of the cleaning ring 14 slides and rubs against the surface of the LED lamp 3, thereby cleaning the LED lamp 3 and preventing insects from entering the lamp cover 2 and hitting the LED lamp 3, leaving body fluid on the surface of the LED lamp 3, which would cause the LED lamp 3 to produce light spots when it emits light.

[0032] An elastic membrane 16 is fixedly attached to the inner side of the cleaning ring 14; the sponge 15 is fixedly attached to the side of the elastic membrane 16 near the LED lamp 3; an elastic block 17 is fixedly attached between the elastic membrane 16 and the inner side of the cleaning ring 14; by setting the elastic membrane 16 and the elastic block 17, during the process of the sponge 15 sliding and rubbing against the surface of the LED lamp 3, the elastic block 17 can always press the sponge 15 tightly against the surface of the LED lamp 3, thereby improving the adhesion between the sponge 15 and the surface of the LED lamp 3, thus adapting to LED lamps of different shapes, improving the cleaning effect of the sponge 15 on the LED lamp 3, and increasing the cleanable area.

[0033] Preferably, a C-shaped frame 18 is fixedly connected to the lower end of the piston tube 11; a second pull rope 19 is fixedly connected between the inner side of the elastic membrane 16 and the bottom end of the C-shaped frame 18; the second pull rope 19 passes through the elastic block 17, the cleaning ring 14 and the piston rod 12, and the second pull rope 19 is slidably connected to the elastic block 17, the cleaning ring 14 and the piston rod 12; when the piston rod 12 moves downward, the second pull rope 19 is relaxed, and the elastic block 17 can press the sponge 15 onto the surface of the LED lamp 3 and clean it; when the elastic strip 13 pulls the piston rod 12 upward to reset, the second pull rope 19 is gradually tightened, so that after the cleaning ring 14 is reset to the limit position, the second pull rope 19 pulls the elastic membrane 16 and moves the sponge 15 away from the surface of the LED lamp 3, avoiding the problem of poor heat dissipation when the LED lamp 3 is working normally.

[0034] The lamp holder 1 is a hollow structure; a receiving dish 20 is provided below the lampshade 2, and the receiving dish 20 is fixedly connected to and communicates with the lamp holder 1; a trash can 21 is installed at the bottom of the lamp holder 1, and the lamp holder 1 and the trash can 21 are connected by an inclined tube 22; a filter screen 23 is fixedly connected to the lamp holder 1 near the inclined tube 22; by setting the trash can 21, the functionality of the lamp can be improved. At the same time, when the light-transmitting plate 4 rotates and hangs down, the insect corpses on the upper side of the light-transmitting plate 4 can slide into the receiving dish 20, and finally enter the trash can 21 through the lamp holder 1 and the inclined tube 22, avoiding the problem of the light-transmitting plate 4 directly scattering insects on the ground, affecting the aesthetics of the garden road, and avoiding the tedious operation of cleaning workers cleaning each section separately.

[0035] An expansion water-stop strip 24 is fixedly connected to the inclined tube 22, and the expansion water-stop strip 24 is made of water-absorbing material. On rainy days, rainwater enters the lamp holder 1 through the receiving dish 20, which washes the inner wall of the receiving dish 20 and the lamp holder 1, preventing insect body fluids from flowing out and adhering to the inner wall or filter screen 23, causing blockage. At the same time, the expansion water-stop strip 24 expands rapidly when it comes into contact with water and seals the inclined tube 22, preventing a large amount of rainwater from entering the garbage can 21 and causing the garbage to deteriorate. When the expansion water-stop strip 24 dries and shrinks, the inclined hole is no longer sealed, and the insects accumulated on the upper side of the filter screen 23 will naturally slide into the garbage can 21.

[0036] A rotating shaft 25 is rotatably connected to the lamp holder 1 below the filter screen 23 via a bracket; an auger 26 is fixedly connected to the outside of the rotating shaft 25; a pair of swing bars 27 are fixedly connected to one end of the rotating shaft 25 extending to the upper side of the filter screen 23, and the rotating shaft 25 is rotatably connected to the filter screen 23; when rainwater flows downward inside the lamp holder 1, it will push the auger 26 to rotate, and then the auger 26 will drive the rotating shaft 25 and the swing bars 27 to rotate. The swing bars 27 scrape the surface of the filter screen 23, thereby peeling off the insects adhering to the surface of the filter screen 23. When the expansion sealing strip 24 dries and shrinks, the oblique hole is no longer sealed, and the insect corpses accumulated on the upper side of the filter screen 23 will naturally slide into the trash can 21.

[0037] Several No. 1 springs 28 are fixedly connected to the inner wall of the lamp holder 1 near the auger 26; a small ball 29 is fixedly connected to the free end of each No. 1 spring 28; by setting the No. 1 springs 28 and the small ball 29, when the water flow drives the auger 26 to rotate, the auger 26 will intermittently poke the small ball 29 and deform the No. 1 springs 28. When the auger 26 separates from the small ball 29, the small ball 29 swings back under the action of the No. 1 spring 28 and hits the inner wall of the lamp holder 1, causing the lamp holder 1 and the filter screen 23 to vibrate. Accompanied by the scraping effect of the swing bar 27, the separation efficiency between insects and the filter screen 23 is further improved.

[0038] Example 2

[0039] like Figure 6 As shown in the first embodiment, as another implementation of the present invention, the reel 6 has a plurality of first magnets 30 evenly arranged around its circumference; the first pull rope 7 has a plurality of second magnets 31 evenly arranged at intervals inside; when the first pull rope 7 is wound around the reel 6, the first magnets 30 and second magnets 31 are close to each other, and the magnetic poles of the first magnets 30 and second magnets 31 are opposite at the positions where they are close to each other; during the process of the reel 6 rotating and the first pull rope 7 being released, the first pull rope 7 is tightly attached to the surface of the reel 6 due to the mutual attraction between the first magnets 30 and second magnets 31. When the tension on the first pull rope 7 is greater than the attraction between the first magnets 30 and second magnets 31, the first pull rope 7 will quickly detach from the reel 6, and then the first pull rope 7 will drive the light-transmitting plate 4 to shake slightly, shaking off the insects on the upper side of the light-transmitting plate 4, thus improving the cleaning effect.

[0040] The roller 6 has several evenly spaced sliding holes 32 around its circumference, and a first magnet 30 is slidably connected in the sliding hole 32. A second spring 33 is fixed between the outer end of the sliding hole 32 and the first magnet 30. As the roller 6 rotates and the first pull rope 7 is released, the first magnet 30 and the second magnet 31 attract each other, causing the first magnet 30 to move toward the first pull rope 7 and compress the second spring 33. When the first pull rope 7 quickly disengages from the roller 6, the first magnet 30, under the pushing force of the second spring 33, strikes the inner end of the sliding hole 32, causing the roller 6 and the first pull rope 7 to shake, further shaking off the insects on the upper side of the light-transmitting plate 4 and improving the cleaning effect.

[0041] Working Principle: After prolonged use, the lampshade 2 easily accumulates many insect corpses. By periodically activating the dual-head motor, the drive shaft rotates, which in turn drives the roller 6, loosening the No. 1 pull rope 7 wound on the roller 6. This causes the light-transmitting plate 4 to naturally rotate and droop under its own weight, allowing the insect corpses on the upper side of the light-transmitting plate 4 to slide off, thus cleaning the inside of the lampshade 2. This prevents excessive insects from affecting the aesthetics of the lamp. After cleaning, the dual-head motor drives the drive shaft in reverse to pull the light-transmitting plate 4 to a horizontal position. When the dual-head motor drives the solid shaft 8 and hollow shaft 9 to rotate, because the hollow shaft 9 is connected to the lampshade 2 via a screw and nut pair, the roller 6 moves towards the inner wall of the lampshade 2. The airbag 10 is moved and squeezed, causing the gas in the airbag 10 to enter the piston tube 11 through the conduit, pushing the piston rod 12 downwards. This, in turn, causes the cleaning ring 14 to move downwards as well. The sponge 15 on the inner side of the cleaning ring 14 slides and rubs against the surface of the LED lamp 3, thereby cleaning the LED lamp 3 and preventing insects from entering the lamp cover 2 and hitting the LED lamp 3, leaving body fluids on the surface of the LED lamp 3, which would cause light spots when the LED lamp 3 emits light. By setting the elastic membrane 16 and the elastic block 17, during the up-and-down sliding friction between the sponge 15 and the surface of the LED lamp 3, the elastic block 17 can always press the sponge 15 firmly against the surface of the LED lamp 3, improving the adhesion between the sponge 15 and the surface of the LED lamp 3, thus appropriately... To improve the cleaning effect of the sponge 15 on the LED lamps 3, which have different shapes, and increase the cleanable area, when the piston rod 12 moves downward, the second pull rope 19 is relaxed, and the elastic block 17 can press the sponge 15 onto the surface of the LED lamp 3 and clean it. When the elastic strip 13 pulls the piston rod 12 upward to reset, the second pull rope 19 is gradually tightened, so that after the cleaning ring 14 resets to its limit position, the second pull rope 19 pulls the elastic membrane 16 and moves the sponge 15 away from the surface of the LED lamp 3, avoiding the problem of poor heat dissipation when the LED lamp 3 is working normally. By setting up the trash can 21, the functionality of the lamp can be improved. At the same time, when the light-transmitting plate 4 rotates and hangs down, the insect corpses on the upper side of the light-transmitting plate 4 can slide to the support. The insects are collected in the receiving dish 20 and eventually enter the trash can 21 through the lamp holder 1 and the inclined tube 22. This prevents the light-transmitting plate 4 from directly sprinkling insects on the ground, which would affect the aesthetics of the garden path and avoid the tedious operation of cleaning workers cleaning each section individually. On rainy days, rainwater enters the lamp holder 1 through the receiving dish 20 and washes the inner walls of the receiving dish 20 and the lamp holder 1, preventing insect body fluids from flowing out and adhering to the inner wall or filter screen 23, causing blockage. At the same time, the expansion water-stop strip 24 expands rapidly when it comes into contact with water and seals the inclined tube 22, preventing a large amount of rainwater from entering the trash can 21 and causing the trash to deteriorate. When the expansion water-stop strip 24 dries and shrinks, the inclined hole is no longer sealed, and the insects accumulated on the upper side of the filter screen 23 will naturally slide into the trash can 21.As rainwater flows downwards inside the lamp holder 1, it drives the auger 26 to rotate. The auger 26 then drives the rotating shaft 25 and the swing bar 27 to rotate. The swing bar 27 scrapes the surface of the filter screen 23, thus removing insects adhering to it. When the expansion stop strip 24 dries and shrinks, the oblique holes are no longer sealed, and the insect carcasses remaining on the upper side of the filter screen 23 will naturally slide into the trash can 21. By setting a first spring 28 and a small ball 29, when the water flow drives the auger 26 to rotate, the auger 26 will intermittently agitate the small ball 29 and deform the first spring 28. When the auger 26 disengages from the small ball 29, the small ball 29 swings back under the action of the first spring 28 and strikes the inner wall of the lamp holder 1, causing the lamp holder 1 and the filter screen 23 to vibrate. Combined with the scraping effect of the swing bar 27, this further improves the separation efficiency between insects and the filter screen 23. The reel 6 rotates and releases the first pull rope 7. During the loosening process, the attraction between magnet 30 and magnet 31 causes the pull rope 7 to adhere tightly to the surface of the roller 6. When the tension on pull rope 7 exceeds the attraction between magnet 30 and magnet 31, pull rope 7 quickly separates from roller 6. This causes pull rope 7 to vibrate the light-transmitting plate 4 slightly, shaking off insects on the upper side of the plate and improving the cleaning effect. As roller 6 rotates and pull rope 7 is loosened, the attraction between magnet 30 and magnet 31 causes magnet 30 to move towards pull rope 7 and compress spring 33. When pull rope 7 quickly separates from roller 6, magnet 30, under the thrust of spring 33, strikes the inner end of sliding hole 32, causing roller 6 and pull rope 7 to vibrate, further shaking off insects on the upper side of light-transmitting plate 4 and improving the cleaning effect.
