Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, specifically a lighting fixture for indoor lighting. Background Technology

[0002] Chandeliers are high-end decorative lighting fixtures suspended from indoor ceilings. Crystal chandeliers are suitable for living rooms, bedrooms, dining rooms, corridors, hotel lobbies, etc. However, the more beautiful chandeliers usually have more complex shapes and lampshades. If the environment is damp and dusty, the lamps are prone to rust and paint peeling, and the lampshades become dim due to dust accumulation.

[0003] According to CN1184433C, the variable angle reflective straight tube fluorescent lamp uses rare earth tri-color low-energy fluorescent tubes, achieving a color rendering index of over 90Ra, resulting in significant improvements in color reproduction and visual effects. The use of rare earth tri-color phosphors allows for a longer tube, reducing tube power, current consumption, and ultraviolet radiation. Furthermore, the inclusion of a PTC circuit in the matching high-power electronic ballast extends the tube life by over 20,000 hours. The variable angle mechanism of the lamp provides adjustability for lighting position and direction, increasing the illumination area, reducing the number of lamps required, expanding the lighting effect of the illuminated area, and enabling directional lighting.

[0004] However, in the existing technology, indoor lighting fixtures are mostly located at the top of the room. After a long period of use, the bulbs inside the fixtures are prone to damage. The bulbs inside the fixtures are designed in a standardized way so that they can be directly replaced with new ones. However, due to the high position of the fixtures, it is difficult to replace the bulbs in practice. In particular, it requires climbing to replace them, which is quite dangerous.

[0005] Therefore, the present invention proposes a lamp for indoor lighting. Summary of the Invention

[0006] To address the issue that in existing technologies, indoor lighting fixtures are mostly located at the ceiling, and the bulbs inside are prone to damage after prolonged use, the bulbs inside the fixtures are standardized and can be directly replaced. However, due to the high position of the fixtures, replacing the bulbs is difficult in practice, especially since it requires climbing to replace them, which is quite dangerous. Therefore, this invention proposes a lighting fixture for indoor lighting.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A lamp for indoor lighting, comprising a mounting base, a bulb, and a reel; the mounting base is fixed to the ceiling of the room; a storage box is fixedly connected inside the mounting base; a reel is fixedly connected inside the storage box; a spring is wound around the surface of the reel; an electric wire is fixedly connected to the end of the spring; a guide plate is rotatably connected inside the mounting base near the reel; a mounting block is fixedly connected to the bottom of the electric wire; a mounting groove is formed on the bottom surface of the mounting base; a pull rod is fixedly connected to the side of the mounting block; a bulb is connected to the bottom of the mounting block; when the bulb needs to be replaced during operation, the pull rod can be pulled down directly by the operating lever, which can be purchased together with the lamp. The pull rod then moves the mounting block downwards, which in turn moves the bulb downwards. During this process, because the wire connects the reel and the mounting block, the mounting block is always pulled back by the wire. After the mounting block is fully pulled down, people can stand on the ground to change the bulb. After changing the bulb, the mounting base is guided back into the mounting slot by the operating rod in conjunction with the pull back of the wire. This invention effectively facilitates the quick replacement of bulbs inside high-position lighting fixtures. Because the mounting block is always pulled back by the elastic plate inside the reel, it can be lowered and automatically reset. Therefore, the bulb replacement process can be completed on the ground, which is convenient and quick, and reduces the various dangers caused by climbing to change bulbs.

[0008] Preferably, the mounting block has a sliding groove on its side; a slider is slidably connected inside the sliding groove; a first spring is fixedly connected between the slider and the bottom of the sliding groove; a first airbag is fixedly connected to the surface of the slider near the opening of the sliding groove; a rotating groove is formed on the surface of the slider; a rotating block is rotatably connected inside the rotating groove; a second spring is fixedly connected between the rotating block and the bottom of the rotating groove; a limit groove is formed on the inner side of the mounting groove; a control groove is formed on the top surface of the pull rod; a control block is slidably connected inside the control groove; a second airbag is fixedly connected between the control block and the bottom of the control groove, and the second airbag and the first airbag are interconnected through a pipe; during operation... By setting a first airbag and a second airbag, in order to avoid the elastic sheet being continuously stretched by the gravity of the mounting block and the bulb, when the mounting block is retracted into the mounting groove, the rotating block on one side of the mounting block will automatically engage with the limiting groove to complete the limiting and fixing of the mounting block. When the mounting block needs to be pulled out downwards, the operating rod will squeeze the control block, which in turn will squeeze the second airbag, causing the gas inside the second airbag to be introduced into the first airbag. The first airbag expands, and then the first airbag will drive the slider to retract into the bottom of the sliding groove. At the same time, the slider will drive the rotating block to exit the limiting groove. At this time, pulling down the lever can automatically pull out the mounting block. Through the above limiting design, the positional stability after the bulb is replaced is ensured.

[0009] Preferably, a first gear is fixedly connected to the side of the guide plate; a second gear is rotatably connected inside the mounting base, and the second gear meshes with the first gear; a rotating rod is fixedly connected to the side of the second gear; the surface of the rotating rod is threaded; a conductive block is rotatably connected to the surface of the rotating rod, and the conductive block is electrically connected to the wire; a fixing block is fixedly connected inside the mounting base near the conductive block; a conductive sheet is fixedly connected inside the fixing block, and the conductive sheet is electrically connected to the power source; push blocks are slidably connected to the sides of the fixing block; a third spring is fixedly connected between the push block and the fixing block; during operation, when the wire is pulled down, the wire will drive the guide plate to rotate, and the guide plate will drive... The first gear rotates, driving the second gear to rotate via meshing. The second gear then drives the rotating rod to rotate, and the threads on the rotating rod's surface cause the conductive block to move. When the wire is pulled down, the conductive block separates from the conductive plate, automatically cutting off the power. Conversely, when the wire moves upward and is wound up, the circuit automatically connects, ensuring automatic power cut-off when changing light bulbs and preventing electric shock accidents. Simultaneously, a push block is provided. Due to the limited total length of the rotating rod's threads, when the conductive block exits the threaded surface, the rotating rod rotates in the opposite direction, preventing the conductive block from smoothly returning. A third spring then drives the push block to move and automatically press the conductive block, ensuring the normal reciprocating motion of the electric block.

[0010] Preferably, the bottom of the mounting block is fixed to a lighting lamp near the bulb, and the power of the lighting lamp is less than that of the bulb. During operation, by setting up the lighting lamp, the circuit where the bulb is located is automatically powered off during the bulb replacement process, which is especially inconvenient at night when the environment is dark. The continuously lit lighting lamp can play an auxiliary lighting role.

[0011] Preferably, a third airbag is fixedly connected to the bottom of the mounting groove; an arc-shaped groove is formed on the bottom surface of the mounting base, and the arc-shaped groove and the third airbag are interconnected by a pipe; an arc-shaped rod is slidably connected inside the arc-shaped groove; a lampshade is rotatably connected to the bottom surface of the mounting base, and the lampshade is fixedly connected to the arc-shaped rod; during operation, by setting the third airbag, when the mounting block is retracted into the mounting groove, the third airbag at the bottom of the mounting groove will be squeezed by the mounting block, causing the gas inside the third airbag to be introduced into the arc-shaped groove, thereby causing the arc-shaped rod inside the arc-shaped groove to be discharged, and the arc-shaped rod will drive the lampshade to rotate, realizing the automatic closing of the lampshade; conversely, when the mounting block moves downward, the lampshade automatically rotates and opens.

[0012] Preferably, a pressure plate is fixedly connected to the bottom surface of the mounting base; a fourth airbag is fixedly connected to the end face of the lampshade; an air guide hole is provided inside the lampshade; evenly arranged adjustment grooves are provided inside the air guide hole; decorative blocks are slidably connected inside each adjustment groove; a telescopic piece is fixedly connected between the decorative block and the inner surface of the adjustment groove; during operation, by setting the fourth airbag, when the lampshade is closed, the lampshade will drive the fourth airbag to move, so that the fourth airbag is in direct contact with the pressure plate. When the fourth airbag is squeezed, the gas inside it will be introduced into the air guide hole, which will promote the decorative block inside the air guide hole to push out of the corresponding adjustment groove. The decorative block can play a decorative and aesthetic role. At the same time, when the lampshade is opened, due to the shaking caused by rotation, the decorative block will retract, which can realize automatic protection of the decorative part.

[0013] Preferably, the decorative block has a through hole on its surface; a connecting pipe is fixedly connected to the top surface of the decorative block at the through hole; a first spherical shell is fixedly connected to the top surface of the connecting pipe; a second spherical shell is sleeved on the outside of the first guide ball, and the second spherical shell is slidably connected to the connecting pipe; a sealing membrane is fixedly connected between the first spherical shell and the second spherical shell at the bottom of the first spherical shell; an air hole is formed on the surface of the connecting pipe near the sealing membrane; during operation, when the lampshade is closed, the decorative block corresponds to the adjustment groove, and the decorative block will drive the connecting pipe to move, which in turn will drive the first spherical shell to move. The second spherical shell is pushed upward by the lampshade, causing the first and second spherical shells to move relative to each other. At the same time, the sealing membrane between the first and second spherical shells is compressed, and the gas inside the sealing membrane is introduced into the through hole through the air hole and continuously and slowly sprayed out through the decorative block, thus blowing air onto the bottom surface of the lampshade after wiping and promoting the drying of the bottom surface of the lampshade. Conversely, when the lampshade is about to be opened, if the lampshade has been used for a long time and there is a lot of dust on its surface, the dust on the surface of the lampshade is easily dropped when it is shaken. At this time, the sealing membrane rebounds and the through hole draws inward, promoting the internal absorption of dust in the air.

[0014] Preferably, the top surface of the first spherical shell has a first guide hole; the top of the second spherical shell has a second vent hole; a pair of control springs are fixedly connected to the top surface of the first spherical shell at the first guide hole; an insert is fixedly connected to the inner surface of the second spherical shell at the second vent hole; a connecting groove is formed on the surface of the insert; an elastic membrane is fixedly connected between the first and second spherical shells; during operation, by setting the insert and control springs, when the lampshade is closed, the lampshade is in a completely sealed state. After the bulb has been used for a long time, the air inside the lampshade cannot circulate with the outside air, resulting in a high internal temperature of the lampshade. When the lampshade is rotated to close, the connecting tube will drive the first spherical shell to move downward. At this time, the connecting groove on the surface of the insert is located on both sides of the control spring, and the inside of the lampshade is connected to the outside, ensuring that the lampshade is closed. The through hole is open and connects the inside and outside of the lampshade, which is beneficial for heat dissipation.

[0015] Preferably, the decorative block has spray holes on its surface; a telescopic spring is fixedly connected inside the spray hole; the telescopic spring has a cross-shaped basic structure; a uniformly arranged fourth spring is fixedly connected to the surface of the telescopic spring; an elastic sheet is filled between the telescopic spring and the spray hole; during operation, by setting the telescopic spring, when air is drawn in and expelled through the spray hole, due to the small overall diameter of the through hole, the impact force of the expelled gas is large in the early stage, while the expelling effect is greatly weakened in the later stage, and the same problem occurs with air intake. Therefore, by setting a telescopic spring inside the spray hole, under the action of the fourth spring, the size of the spray hole opening can be automatically adjusted.

[0016] Preferably, a ball groove is formed inside the decorative block near the bottom; a grinding ball is provided inside the ball groove; a connecting rope is fixed between the grinding ball and the inner surface of the ball groove; a telescopic groove is formed on the surface of the grinding ball near the bottom; an intercepting rod is slidably connected inside the telescopic groove; the surface of the intercepting rod is designed with a uniformly arranged barbed structure; an air guide block is fixed inside the ball groove near the bottom, and the air guide block is interconnected with the through hole; during operation, by setting the grinding ball, when external gas is drawn into the through hole through the nozzle, the gas will first be drawn into the ball groove. If a small insect is drawn into the ball groove, the insect will be intercepted by the barbed structure on the surface of the intercepting rod. When the gas is discharged in the opposite direction, the air guide block at the bottom of the grinding ball will blow the grinding ball upward, causing the grinding ball to move up and down. The grinding ball will repeatedly squeeze the intercepting rod, causing the intercepting rod to automatically retract. Insects on the surface of the intercepting rod will also detach from the intercepting rod and be squeezed and ground by the grinding ball, which facilitates the crushing and discharge of insects and reduces the problem of blockage of the through hole, ball groove and nozzle.

[0017] The advantages of this invention are:

[0018] 1. This invention, by setting up a mounting base, a light bulb, and a reel, effectively facilitates the quick replacement of light bulbs inside high-position lighting fixtures through the winding action of the reel on the wire. Because the reel is constantly pulled back by the elastic sheet inside, the mounting block can be lowered and automatically reset. Therefore, the bulb replacement can be completed on the ground, which is convenient and quick, and reduces the various dangers caused by climbing to change the bulb.

[0019] 2. This invention, by setting up a decorative block, a first spherical shell, and a second spherical shell, allows the decorative block to move in response to the adjustment groove when the lampshade is closed. This movement causes the connecting pipe to move, which in turn causes the first spherical shell to move. As the second spherical shell is pushed upward by the lampshade, the first and second spherical shells move relative to each other. Simultaneously, the sealing membrane between the first and second spherical shells is compressed, and the gas inside the sealing membrane is introduced into the through hole through the air hole and continuously and slowly sprayed out through the decorative block. This blows air onto the bottom surface of the lampshade after wiping, promoting its drying. Conversely, when the lampshade is about to be opened, if it has been used for a long time and has accumulated a lot of dust on its surface, the dust can easily fall off when the lampshade is shaken. At this time, the sealing membrane rebounds, and the through hole draws inward, promoting the internal absorption of dust from the air. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1-7As shown, a lamp for indoor lighting includes a mounting base 1, a bulb 2, and a reel 3. The mounting base 1 is fixed to the ceiling of the room. A storage box is fixedly connected inside the mounting base 1. The reel 3 is fixedly connected inside the storage box. A spring sheet 4 is wound around the surface of the reel 3. An electric wire 5 is fixedly connected to the end of the spring sheet 4. A guide plate 6 is rotatably connected inside the mounting base 1 near the reel 3. A mounting block 7 is fixedly connected to the bottom of the electric wire 5. A mounting groove is formed on the bottom surface of the mounting base 1. A pull rod 8 is fixedly connected to the side of the mounting block 7. The bulb 2 is connected to the bottom of the mounting block 7. When the bulb 2 needs to be replaced during operation, the pull rod 8 can be pulled down directly by the operating lever. This operating lever can be purchased together with the lamp. The pull rod 8 will then drive the mounting block. 7 moves downwards, and the mounting block 7 will in turn drive the bulb 2 downwards. During this process, since the wire 5 connects the reel 3 and the mounting block 7, the mounting block 7 is always pulled back by the wire 5. After the mounting block 7 is completely pulled down, people can stand on the ground to replace the bulb 2. After replacing the bulb 2, the mounting base 1 is guided back into the mounting slot by the operating lever in conjunction with the pull back action of the wire 5. This invention effectively facilitates the quick replacement of the bulb 2 inside the high-position lamp. Since the mounting block 7 is always pulled back by the elastic sheet 41 inside the reel 3 during this process, it can be lowered and can also be automatically reset. Therefore, the replacement of the bulb 2 can be completed on the ground, which is convenient and quick, and reduces the various dangers caused by climbing to replace the bulb 2.

[0034] The mounting block 7 has a sliding groove on its side; a slider 9 is slidably connected inside the sliding groove; a first spring 10 is fixedly connected between the slider 9 and the bottom of the sliding groove; a first airbag 11 is fixedly connected to the surface of the slider 9 near the opening of the sliding groove; a rotating groove is formed on the surface of the slider 9; a rotating block 12 is rotatably connected inside the rotating groove; a second spring 13 is fixedly connected between the rotating block 12 and the bottom of the rotating groove; a limit groove is formed on the inner side of the mounting groove; a control groove is formed on the top surface of the pull rod 8; a control block 14 is slidably connected inside the control groove; a second airbag 15 is fixedly connected between the control block 14 and the bottom of the control groove, and the second airbag 15 and the first airbag 11 are interconnected through a pipe; during operation, by setting the first To prevent the elastic sheet 41 from being continuously stretched by the gravity of the mounting block 7 and the bulb 2, the rotating block 12 on one side of the mounting block 7 will automatically engage with the limiting groove when the mounting block 7 is retracted into the mounting groove, thus fixing the mounting block 7 in place. When the mounting block 7 needs to be pulled out, the operating lever will press the control block 14, which in turn will press the second airbag 15, causing the gas inside the second airbag 15 to be introduced into the first airbag 11. The first airbag 11 will expand, and then the first airbag 11 will drive the slider 9 to retract into the bottom of the sliding groove. At the same time, the slider 9 will drive the rotating block 12 to exit the limiting groove. At this time, pulling down the lever 8 can automatically pull out the mounting block 7. Through the above limiting design, the positional stability of the bulb 2 after replacement is ensured.

[0035] A first gear 16 is fixedly connected to the side of the guide plate 6; a second gear 17 is rotatably connected inside the mounting base 1, and the second gear 17 meshes with the first gear 16; a rotating rod 18 is fixedly connected to the side of the second gear 17; the surface of the rotating rod 18 is threaded; a conductive block 19 is rotatably connected to the surface of the rotating rod 18, and the conductive block 19 is electrically connected to the wire 5; a fixing block 20 is fixedly connected inside the mounting base 1 near the conductive block 19; a conductive sheet 21 is fixedly connected inside the fixing block 20, and the conductive sheet 21 is electrically connected to the power source; push blocks 22 are slidably connected inside the fixing block 20 near both sides; a third spring 23 is fixedly connected between the push block 22 and the fixing block 20; during operation, when the wire 5 is pulled down, the wire 5 will drive the guide plate 6 to rotate. The first gear 16 rotates, which in turn drives the second gear 17 to rotate. The second gear 17 then drives the rotating rod 18 to rotate. The threads on the surface of the rotating rod 18 move the conductive block 19. When the wire is pulled down, the conductive block 19 separates from the conductive sheet 21, achieving automatic power cut-off. Conversely, when the wire moves upward and is wound up, the circuit is automatically connected, ensuring automatic power cut-off when replacing the bulb 2 and preventing electric shock accidents during bulb replacement. At the same time, by setting the push block 22, since the total length of the threads on the rotating rod 18 is limited, when the conductive block 19 exits the surface of the threaded position, the rotating rod 18 rotates in the opposite direction, and the conductive block 19 cannot be smoothly guided back. Through the action of the third spring 23, the third spring 23 drives the push block 22 to move and automatically squeeze the conductive block 19, ensuring the normal reciprocating motion of the electric block.

[0036] The bottom of the mounting block 7 is fixed to the lighting lamp 24 near the bulb 2, and the power of the lighting lamp 24 is less than that of the bulb 2. During operation, by setting the lighting lamp 24, the circuit where the bulb 2 is located is automatically powered off during the replacement of the bulb 2, which causes a lot of inconvenience, especially at night when the environment is dark. The lighting lamp 24, which is continuously lit, can play an auxiliary lighting role.

[0037] The bottom of the mounting groove is fixedly connected to a third airbag 25; the bottom surface of the mounting base 1 is provided with an arc-shaped groove, and the arc-shaped groove and the third airbag 25 are interconnected by a pipe; an arc-shaped rod 26 is slidably connected inside the arc-shaped groove; a lampshade 27 is rotatably connected to the bottom surface of the mounting base 1, and the lampshade 27 is fixedly connected to the arc-shaped rod 26; during operation, by setting the third airbag 25, when the mounting block 7 is retracted into the mounting groove, the third airbag 25 at the bottom of the mounting groove will be squeezed by the mounting block 7, so that the gas inside the third airbag 25 is introduced into the arc-shaped groove, thereby causing the arc-shaped rod 26 inside the arc-shaped groove to be discharged. The arc-shaped rod 26 will drive the lampshade 27 to rotate, realizing the automatic closing of the lampshade 27. Conversely, when the mounting block 7 moves downward, the lampshade 27 automatically rotates and opens.

[0038] A pressure plate 28 is fixedly connected to the bottom surface of the mounting base 1; a fourth airbag 29 is fixedly connected to the end face of the lampshade 27; an air guide hole is provided inside the lampshade 27; an evenly arranged adjustment groove is provided inside the air guide hole; a decorative block 30 is slidably connected inside each adjustment groove; a telescopic piece 31 is fixedly connected between the decorative block 30 and the inner surface of the adjustment groove; during operation, by setting the fourth airbag 29, when the lampshade 27 is closed, the lampshade 27 will drive the fourth airbag 29 to move, so that the fourth airbag 29 is in direct contact with the pressure plate 28. When the fourth airbag 29 is squeezed, the gas inside it will be introduced into the air guide hole, which will promote the decorative block 30 inside the air guide hole to push out of the corresponding adjustment groove. The decorative block 30 can play a decorative and aesthetic role. At the same time, when the lampshade 27 is opened, due to the shaking caused by rotation, the decorative block 30 will retract, which can realize automatic protection of the decorative part.

[0039] The decorative block 30 has a through hole on its surface; a connecting pipe 32 is fixedly connected to the top surface of the decorative block 30 at the through hole; a first spherical shell 33 is fixedly connected to the top surface of the connecting pipe 32; a second spherical shell 34 is sleeved on the outside of the first guide ball, and the second spherical shell 34 is slidably connected to the connecting pipe 32; a sealing membrane 35 is fixedly connected between the first spherical shell 33 and the second spherical shell 34 at the bottom of the first spherical shell 33; an air hole is opened on the surface of the connecting pipe 32 near the sealing membrane 35; during operation, when the lampshade 27 is closed, the decorative block 30 corresponds to the adjustment groove, and the decorative block 30 will drive the connecting pipe 32 to move, and the connecting pipe 32 will drive the first spherical shell 33 to move. As the second spherical shell 34 is pushed upward by the lampshade 27, the first spherical shell 33 and the second spherical shell 34 move relative to each other. At the same time, the sealing membrane 35 between the first spherical shell 33 and the second spherical shell 34 is compressed. The gas inside the sealing membrane 35 is introduced into the through hole through the air hole and continuously and slowly sprayed out through the decorative block 30, so as to blow air on the bottom surface of the lampshade 27 after wiping and promote the drying of the bottom surface of the lampshade 27. Conversely, when the lampshade 27 is about to be opened, if the lampshade 27 has been used for a long time and there is a lot of dust on its surface, the dust on the surface of the lampshade 27 is easily dropped when shaken. At this time, the sealing membrane 35 rebounds and the through hole draws inward, promoting the internal absorption of dust in the air.

[0040] The first spherical shell 33 has a first guide hole on its top surface; the second spherical shell 34 has a second vent hole on its top surface; a pair of control springs 36 are fixedly connected to the top surface of the first spherical shell 33 at the first guide hole; an insertion tube 37 is fixedly connected to the inner surface of the second spherical shell 34 at the second vent hole; a connecting groove is formed on the surface of the insertion tube 37; an elastic membrane 38 is fixedly connected between the first spherical shell 33 and the second spherical shell 34; during operation, by setting the insertion tube 37 and the control springs 36, when the lamp cover 27 is closed, the lamp cover 27 is in a completely sealed state. After the bulb 2 has been used for a long time, the air inside the lamp cover 27 cannot circulate with the outside air, resulting in a high internal temperature of the lamp cover 27. When the lamp cover 27 is rotated to close, the connecting tube 32 will drive the first spherical shell 33 to move downward. At this time, the connecting groove on the surface of the insertion tube 37 is located on both sides of the control springs 36. At this time, the inside of the lamp cover 27 is connected to the outside, ensuring that the lamp cover 27 is closed and the through hole is open, connecting the inside and outside of the lamp cover 27, which is beneficial for heat dissipation.

[0041] The decorative block 30 has spray holes on its surface; a telescopic spring 39 is fixedly connected inside the spray hole; the telescopic spring 39 has a cross-shaped basic structure; a uniformly arranged fourth spring 40 is fixedly connected to the surface of the telescopic spring 39; an elastic sheet 41 is filled between the telescopic spring 39 and the spray hole; during operation, by setting the telescopic spring 39, when air is drawn in and expelled through the spray hole, due to the small overall diameter of the through hole, the impact force of the expelled gas is large in the early stage, while the expelling effect is greatly weakened in the later stage, and the same problem occurs when drawing in air. Therefore, by setting the telescopic spring 39 inside the spray hole, under the action of the fourth spring 40, the size of the spray hole opening can be automatically adjusted.

[0043] Please see Figure 8 and Figure 9As shown, a ball groove is formed inside the decorative block 30 near its bottom; a grinding ball block 42 is provided inside the ball groove; a connecting rope 43 is fixedly connected between the grinding ball block 42 and the inner surface of the ball groove; a telescopic groove is formed on the surface of the grinding ball block 42 near its bottom; an intercepting rod 44 is slidably connected inside the telescopic groove; the surface of the intercepting rod 44 has a uniformly arranged barb structure design; an air guide block 45 is fixedly connected inside the ball groove near its bottom, and the air guide block 45 is interconnected with the through hole; during operation, by setting the grinding ball block 42... When external gas is drawn into the through hole through the nozzle, the gas will first be drawn into the ball groove. If small insects are drawn into the ball groove, they will be intercepted by the barbed structure on the surface of the intercepting rod 44. When the gas is discharged in the reverse direction, the air guide block 45 at the bottom of the grinding ball block 42 will blow the grinding ball block 42 upward, causing the grinding ball block 42 to move up and down. The grinding ball will repeatedly squeeze the intercepting rod 44, causing the intercepting rod 44 to automatically retract. The insects on the surface of the intercepting rod 44 will also detach from the intercepting rod 44 and be squeezed and ground by the grinding ball block 42, which facilitates the crushing and discharge of insects and reduces the problem of blockage in the through hole, ball groove and nozzle.

[0044] Working principle: When bulb 2 needs to be replaced, the lever 8 can be pulled down directly using the operating lever. This operating lever can be purchased together with the lamp. The lever 8 will then drive the mounting block 7 downwards, which in turn will drive the bulb 2 downwards. During this process, since the wire 5 connects the reel 3 and the mounting block 7, the mounting block 7 is always pulled back by the wire 5. After the mounting block 7 is fully pulled down, people can stand on the ground to replace bulb 2. After replacing bulb 2, the mounting base 1 is guided back into the mounting slot by the operating lever in conjunction with the pull back action of the wire 5. By setting the first airbag 11 and the second airbag 15, in order to avoid the elastic sheet 41 being continuously stretched by the gravity of the mounting block 7 and the bulb 2, when the mounting block 7... When the bulb 7 is inserted into the mounting slot, the rotating block 12 on one side of the mounting block 7 will automatically engage with the limiting slot, thus fixing the mounting block 7 in place. When the mounting block 7 needs to be pulled out, the operating lever will press the control block 14, which in turn will press the second airbag 15, causing the gas inside the second airbag 15 to be introduced into the first airbag 11. The first airbag 11 will expand, causing the first airbag 11 to drive the slider 9 to be inserted into the bottom of the slide groove. At the same time, the slider 9 will drive the rotating block 12 to exit the limiting slot. At this time, pulling down the pull rod 8 can automatically pull out the mounting block 7. Through the above limiting design, the positional stability of the bulb 2 after replacement is ensured. When the wire 5 is pulled down, the wire 5 will drive the guide plate 6 to rotate, and the guide plate 6 will drive the first gear 16 to rotate. 16 drives the second gear 17 to rotate via meshing. The second gear 17 drives the rotating rod 18 to rotate. The threads on the surface of the rotating rod 18 drive the conductive block 19 to move. When the wire is pulled down, the conductive block 19 separates from the conductive sheet 21, achieving automatic power cut-off. Conversely, when the wire moves upward and is wound up, the circuit is automatically connected, ensuring automatic power cut-off when replacing the bulb 2 and avoiding electric shock accidents during bulb 2 replacement. At the same time, by setting the push block 22, since the total length of the thread of the rotating rod 18 is limited, when the conductive block 19 exits the surface of the thread position, the rotating rod 18 rotates in the opposite direction, and the conductive block 19 cannot be smoothly guided back. Through the action of the third spring 23, the third spring 23 drives the push block 22 to move and automatically squeeze the conductive block 19. This ensures the normal reciprocating motion of the electric block; by setting up the lighting lamp 24, during the replacement of the bulb 2, the circuit where the bulb 2 is located is automatically powered off, especially at night when the environment is dark, causing many inconveniences. The continuously lit lighting lamp 24 can play an auxiliary lighting role; by setting up the third airbag 25, when the mounting block 7 is retracted into the mounting groove, the third airbag 25 at the bottom of the mounting groove will be squeezed by the mounting block 7, so that the gas inside the third airbag 25 is introduced into the arc groove, which in turn causes the arc rod 26 inside the arc groove to be discharged. The arc rod 26 will drive the lamp cover 27 to rotate, realizing the automatic closing of the lamp cover 27. Conversely, when the mounting block 7 moves downward, the lamp cover 27 automatically rotates and opens.By setting a fourth airbag 29, when the lampshade 27 is closed, the lampshade 27 will drive the fourth airbag 29 to move, so that the fourth airbag 29 directly contacts the pressure plate 28. When the fourth airbag 29 is squeezed, the gas inside it will be introduced into the air guide hole, which will promote the decorative block 30 inside the air guide hole to push out of the corresponding adjustment groove. The decorative block 30 can play a decorative and aesthetic role. At the same time, when the lampshade 27 is open, due to the shaking caused by rotation, the decorative block 30 will retract, which can realize automatic protection of the decorative part. When the lampshade 27 is closed, the decorative block 30 corresponds to the adjustment groove, and then the decorative block 30 will drive the connecting pipe 32 to move. The connecting pipe 32 will drive the first spherical shell 33 to move. Since the second spherical shell 34 is pushed upward by the lampshade 27, The first spherical shell 33 and the second spherical shell 34 move relative to each other, and the sealing membrane 35 between the first spherical shell 33 and the second spherical shell 34 is compressed. The gas inside the sealing membrane 35 is introduced into the through hole through the air hole and continuously and slowly sprayed out through the decorative block 30, so as to blow air on the bottom surface of the lampshade 27 after wiping, and promote the drying of the bottom surface of the lampshade 27. Conversely, when the lampshade 27 is about to be opened, if the lampshade 27 has been used for a long time and there is a lot of dust on its surface, the dust on the surface of the lampshade 27 is easily dropped when it is shaken. At this time, the sealing membrane 35 rebounds and the through hole draws inward, promoting the internal suction of dust in the air. By setting the insertion tube 37 and the control spring 36, when the lampshade 27 is closed, the lampshade 27 is in a completely sealed state, and the bulb 2. After prolonged use, the air inside the lampshade 27 cannot circulate with the outside air, resulting in a high internal temperature. When the lampshade 27 is rotated to close, the connecting pipe 32 will drive the first spherical shell 33 to move downwards. At this time, the connecting groove on the surface of the insert 37 is located on both sides of the control spring 36, and the inside of the lampshade 27 is connected to the outside, ensuring that the lampshade 27 is closed and the through hole is open, connecting the inside and outside of the lampshade 27, which is beneficial for heat dissipation. By setting the telescopic spring 39, when air is sucked in and expelled through the nozzle, due to the small overall diameter of the through hole, the impact force of the expelled gas is large in the early stage, but the expelling effect is greatly weakened in the later stage. The same problem exists for suction. Therefore, a telescopic spring 39 is set inside the nozzle. The spring 39, under the action of the fourth spring 40, automatically adjusts the size of the nozzle opening. By setting up the grinding ball block 42, when external gas is drawn into the through-hole through the nozzle, the gas is first drawn into the ball groove. If small insects are drawn into the ball groove, they are intercepted by the barbed structure on the surface of the interceptor rod 44. When the gas is discharged in the reverse direction, the air guide block 45 at the bottom of the grinding ball block 42 blows the grinding ball block 42 upwards, causing it to move up and down. The grinding ball repeatedly squeezes the interceptor rod 44, causing it to automatically retract. Insects on the surface of the interceptor rod 44 also detach from the interceptor rod 44 and are crushed and ground by the grinding ball block 42, facilitating the crushing and discharge of insects and reducing clogging problems in the through-hole, ball groove, and nozzle.
