Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, specifically a household bedside LED lamp. Background Technology

[0002] The bedside LED lamp can meet the lighting needs of reading and newspapers while lying in bed, providing warm and comfortable lighting in the bedroom.

[0003] According to patent application number 2019102289061, an adjustable LED bedside lamp includes a lampshade and a base. An external power cord is connected to the side wall of the base. A Y-shaped rotating seat is rotatably connected to the center of the upper surface of the base. A lower support tube, rotatably connected by a fastening adjusting bolt, is clamped and fixed inside the Y-shaped rotating seat. In this invention, by changing the orientation of the lampshade, the orientation of the LED threaded bulb is changed, reducing the impact of the light direction on the user. By rotating the adjusting ring, the internal threaded tube inside the adjusting ring engages with the serrated plate on the outer wall of the movable tube, thereby driving the lamp holder connected to the top of the movable tube to move up and down. When the lamp holder is completely placed inside the light-shielding sleeve, different light-shielding effects can be adjusted by moving the movable light-shielding plate at the position of the rectangular light-transmitting hole. The novel structure can greatly improve the lighting effect and has certain market application prospects.

[0004] The aforementioned LED bedside lamps are placed directly on the bedside table, but these lamps are unstable and easily knocked over and damaged. Furthermore, while existing bedside tables provide comfortable lighting for sleeping, the LED bedside lamps occupy space. Even when not in use during the day or in brightly lit rooms, the lamps remain on the bedside table, preventing the placement of other items. Removing the LED bedside lamps is also cumbersome. To address these issues, this embodiment designs a household LED bedside lamp that avoids these problems.

[0005] Therefore, this invention proposes a household bedside LED lamp. Summary of the Invention

[0006] To address the problems of existing LED bedside lamps, such as space occupation when installed on bedside tables and poor stability when placed directly on bedside tables, making them prone to being knocked over and damaged, this invention proposes a household LED bedside lamp.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A household bedside LED lamp of this invention includes a housing, inside which a lifting mechanism is provided. The lifting mechanism includes a motor, a gear, a rack, and a column-shaped frame. A through hole is opened at the center of the upper end face of the housing, and the frame is slidably connected within the through hole. A lamp post is fixedly connected to the bottom of the frame. A rack is fixedly connected to the lower end face of the frame. The two sides of the rack are slidably connected to limiting grooves on the inner wall of the housing. The rack meshes with the gear, which is fixedly connected to the output end of the motor. The motor is fixedly connected to the inner wall of the housing. The motor drives the rack to move through the gear. Under the constraint of the limiting grooves on both sides, the frame moves steadily upward, pushing the frame through the through hole to the top of the box. The lamp post is powered on and emits light, providing a warm glow for the horizontal position. The lamp post is installed inside the box and rests on the ground through the box, providing strong stability and resisting external impacts to prevent tipping and damage. When going to sleep at night, simply turn off the power to the lamp post. During the day or when there is sufficient light inside the horizontal position, the motor is reversed, and the rack pulls the frame back into the box, making the top of the frame flush with the top surface of the box. At this time, more items can be placed on the box, providing convenience for the user.

[0008] Preferably, the frame has baffles inside the two adjacent side pillars. One end of the baffle is rotatably connected to the side wall of the two side pillars via a first torsion spring, and one end of the baffle is fixedly connected to a first elastic rope. The end of the first elastic rope passes through the first hole opened inside the lamp post and the rack, and is wound around a roller provided on the inner side wall of the box. The end of the roller is rotatably connected to the roller frame via a second torsion spring. During the upward movement of the frame, one end of the baffle gradually pulls the first elastic rope, and at the same time, the baffle rotates around its hinge point. The baffle opens, and the light emitted by the lamp post shines on the baffle. The light is diffused on the baffle, so that the light fully illuminates the horizontal position, providing a more comfortable resting environment for the user. During the process of the frame being pulled back into the box, the first elastic rope gradually loosens, and the roller, under the torsion line of the second torsion spring, winds up the first elastic rope. Under the torsion of the first torsion spring, the baffle gradually rotates and adheres to the frame, realizing the automatic storage of the baffle.

[0009] Preferably, the inner plate of the baffle is provided with a light strip, and the other end of the baffle is fixedly connected to a second elastic rope. The second elastic rope passes through the side wall of the frame and is fixed to a first elastic rope. The baffle is connected to the first elastic rope through the second elastic rope. When the first elastic rope is wound by the roller, the first elastic rope pulls the second elastic rope. At the same time, the elastic pulling force of the second elastic rope assists the first torsion spring to rotate and attach the baffle to the frame, ensuring that the baffle is effectively and tightly attached to the frame. This ensures that the frame can smoothly retract into the box from the through hole, preventing the other end of the baffle from tilting up and hitting the end of the through hole, which would cause the baffle to be squeezed and broken. In addition, the inner plate of the baffle is provided with a light strip, and the light strip and the light column can be controlled to be de-energized separately. According to the user's needs, the light column can be energized or the light column and the light strip can be energized to provide different levels of brightness for the horizontal type.

[0010] Preferably, a dust suction port is provided at the bottom of the housing, and a receiving plate is fixed to the dust suction port. A filter cover is provided above the receiving plate, and the upper end of the filter cover is fixed to the inner wall of the housing via a flat plate. An airbag is provided above the flat plate, and the air outlet pipe of the airbag passes through the flat plate and the bottom of the housing. The exhaust direction of the air outlet pipe is towards the dust suction port, and a first one-way valve is provided on the air outlet pipe. The air suction pipe of the airbag passes through the flat plate and connects to the inside of the filter cover, and a second one-way valve is provided on the air suction pipe. A push plate is provided above the airbag, and the push plate is fixed to the end of the rack. The exhaust direction of the air outlet pipe is spiral. During the process of the frame retracting into the housing via the rack, the push plate on the rack presses against the airbag, and the gas in the airbag is discharged through the air outlet pipe. The gas pushes the housing... The dust chamber at the bottom impacts below the suction port. As the frame extends out of the chamber, the airbag is no longer compressed, and the outside air flows, carrying the dust from the suction port onto the filter cover. The dust adheres to the filter cover, and some dust falls onto the receiving plate. Gas is then pumped into the airbag from the suction pipe, and the airbag returns to its initial inflated state. Through the cooperation of the push plate, airbag, and filter cover, the dust and flocculent matter deposited at the bottom of the chamber are collected and concentrated inside the chamber, reducing the harm of dust and flocculent matter to the human respiratory tract. The air impact discharge forms an air vortex, which gathers and converges the dust and flocculent matter together. At the same time, the air vortex can also suck dust and flocculent matter from the periphery of the chamber below the suction port, increasing the dust removal area.

[0011] Preferably, the receiving plate is threaded with a dust collection groove, the opening of which faces the filter cover; the lower surface of the push plate is provided with a cleaning cover, which has symmetrical gaps, through which a No. 1 elastic rope passes, and a connecting rod slidably connected to the upper end of the filter cover is fixedly fixed to the plate; during the process of the push plate squeezing the air bag, the push plate pushes down the cleaning cover, which is then placed on the filter cover, and the lower end of the cleaning cover pushes the dust and flocculent material accumulated on the filter cover into the dust collection groove, preventing the dust and flocculent material from floating out of the box again; the exhaust direction of the air outlet pipe is spiral.

[0012] Preferably, the lower edge of the cleaning hood is uniformly provided with multiple protrusions, and the inner wall of the dust collection trough is also provided with multiple layers of protrusions. During the downward movement of the cleaning hood, the protrusions of the cleaning hood press against the protrusions on the inner wall of the dust collection trough, and the two exert pressure and vibration, shaking the dust on the inner wall of the filter cover and the dust collection trough to the bottom of the dust collection trough. At the same time, during the upward movement of the cleaning hood, the protrusions of the cleaning hood press against the protrusions on the inner wall of the dust collection trough, and the two exert pressure and vibration, shaking the dust on the inner wall of the filter cover and the dust collection trough to the bottom of the dust collection trough again, so that the dust and flocculent matter are concentrated and fall to the bottom of the dust collection trough, preventing the dust and flocculent matter from floating out. After the dust collection trough is full, the dust collection trough is rotated off, cleaned, and then reinstalled on the bottom of the box.

[0013] Preferably, the airbag is equipped with a reset mechanism; the reset mechanism includes a compression spring, a V-shaped rod, a push rod, and a support plate; the V-shaped rod is rotatably connected at its middle position, and rubber plates are hinged to both ends of the V-shaped rod. The rubber plates are adhered to the inner top and inner bottom surfaces of the airbag. The inner sides of two adjacent V-shaped rods are connected together by a compression spring. The outer side of the V-shaped rod is rotatably connected to the push rod, and the end of the push rod is rotatably connected to the support plate, which rests against the inner wall of the airbag; after the airbag is compressed by the push plate, the airbag volume gradually shrinks, and the airbag compresses the V-shaped rod through the rubber plates. The V-shaped rod compresses the compression spring, and at the same time, the gas inside the airbag is discharged through the exhaust pipe. After the push plate leaves the airbag, the V-shaped rod quickly returns to its initial state under the elastic force of the compression spring, and quickly lifts the airbag. At the same time, the V-shaped rod pushes the support plate through the push rod, and the support plate quickly lifts the two sides of the airbag, so that the airbag is quickly drawn in, which accelerates the flow rate of gas into the dust suction port, so that more dust or larger particles are also drawn into the surface of the filter cover, thus enhancing the airbag's suction performance and improving the cleaning effect of dust and lint.

[0014] Preferably, the end of the support plate is bent inwards towards the airbag. The bending of the end of the support plate serves two purposes: first, it prevents the airbag from being crushed and squeezed against the support plate, causing the corners of the support plate to rupture the airbag, thus protecting the airbag; second, the V-shaped rod is pressed against the bent part of the support plate, and the reaction force of the support plate pushes the V-shaped rod away, and the auxiliary compression spring pushes the V-shaped rod away, accelerating the V-shaped rod to return to its initial state, thereby accelerating the inflation of the airbag and improving the airbag's suction performance.

[0015] Preferably, the filter cover is provided with multiple collision rods, which are anchor-shaped. One end of the collision rod is fixed to the inner wall of the filter cover, and the other ends of the collision rods are close to each other. The antennae on both sides of the collision rod are arc-shaped and close to the inner wall of the filter cover. The end of the antennae is provided with a sac, and the sac has an air vent. A push-pull rod is fixed to the top surface of the cleaning cover. The end of the push-pull rod is T-shaped. When the cleaning cover is pushed down, the push-pull rod collides with the collision rod. After the collision rod bends and deforms, it detaches from the end of the push-pull rod. Then the collision rod swings up and down, and the antennae collide with the filter cover, shaking off the dust from the filter cover. At the same time, the sac at the end of the antennae is squeezed and deformed, and the gas inside the sac is squeezed out and impacts the filter cover, further shaking off the dust on the filter cover.

[0016] Preferably, the upper part of the box is provided with a drawer, which is slidably connected to the box body; by providing a drawer on the box body, the storage space for the household bedside LED lamp is increased, allowing more items to be placed inside the box.

[0017] The advantages of this invention are: 1. The lamp post is installed inside the enclosure and rests on the ground, providing strong stability and resisting external impacts to prevent tipping and damage. When going to bed at night, simply turn off the power to the lamp post. During the day or when there is sufficient light inside the room, the motor is reversed, and the rack pulls the frame back into the enclosure, making the top of the frame flush with the top of the enclosure. This allows more items to be placed on the enclosure, providing convenience for the user. 2. During the upward movement of the frame, one end of the baffle gradually pulls the No. 1 elastic rope. At the same time, the baffle rotates around its hinge point and opens. The light emitted by the lamp post shines on the baffle, and the light is diffused on the baffle, so that the light fully illuminates the room and provides users with a more comfortable resting environment. 3. Through the cooperation of the push plate, air bag and filter cover, the dust and flocculent matter deposited at the bottom of the box are collected into the box, reducing the harm of dust and flocculent matter to the human respiratory tract.

[0020] 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.

[0021] Example 1: Reference Figure 1-7A household LED bedside lamp includes a housing 1, within which a lifting mechanism is provided. The lifting mechanism includes a motor 2, a gear 3, a rack 4, and a column-shaped frame 5. A through hole 6 is opened at the center of the upper end face of the housing 1, through which the frame 5 is slidably connected. A lamp post 7 is fixedly connected to the bottom of the frame 5. The rack 4 is fixedly connected to the lower end face of the frame 5. The two sides of the rack 4 are slidably connected to limiting grooves 8 on the inner wall of the housing 1. The rack 4 meshes with the gear 3, which is fixedly connected to the output end of the motor 2. The motor 2 is fixedly connected to the inner side wall of the housing 1. Existing bedside tables are equipped with LED bedside lamps to provide a comfortable and pleasant lighting environment for people lying down. However, LED bedside lamps installed on bedside tables take up space. Even when not in use during the day or in relatively bright environments, the LED bedside lamp still stands on the bedside table, making it impossible to place extra items on its surface. Removing the LED bedside lamp is cumbersome. If you directly purchase an LED bedside lamp... The lamp is placed directly on the bedside table, but the stability of the LED bedside lamp is poor, and it is easily knocked over and damaged. To address the above problems, this embodiment designs a household LED bedside lamp that avoids the above problems. The drive motor 2 moves the rack 4 through the gear 3. The rack 4 moves stably upward under the restriction of the two sides of the limiting groove 8, and at the same time pushes the frame 5 through the through hole 6 to the top of the box 1. The lamp post 7 is powered on and emits light, providing a warm light for the bed. The lamp post 7 is installed in the box 1 and sits on the ground through the box 1. It has strong stability and can resist external collisions, avoiding the occurrence of tipping and damage. When going to sleep at night, the lamp post 7 can be turned off. During the day or when there is sufficient light in the bed, the motor 2 is reversed and the rack 4 pulls the frame 5 back into the box 1. At the same time, the upper end of the frame 5 is flush with the upper surface of the box 1. At this time, more items can be placed on the box 1, providing convenience for the user.

[0022] The frame 5 has baffles 9 installed inside the two adjacent side pillars. One end of the baffle 9 is rotatably connected to the side wall of the two side pillars via a first torsion spring 10. A first elastic rope 11 is fixed to one end of the baffle 9. The end of the first elastic rope 11 passes through the first hole 12 opened inside the lamp post 7 and the rack 4, and is wound around a roller 13 installed on the inner side wall of the housing 1. The end of the roller 13 is rotatably connected to the roller 13 frame via a second torsion spring 14. During the ascent of the frame 5, one end of the baffle 9 gradually pulls the first elastic rope 11. Simultaneously, the baffle 9 rotates around its hinge point, opening the baffle 9. The light emitted by the lamp post 7 shines on the baffle 9, causing diffuse reflection on the baffle 9, allowing the light to fully illuminate the interior of the room, providing a more comfortable resting environment for the user. As the frame 5 is pulled back into the box 1, the first elastic rope 11 gradually loosens, and the roller 13, under the torque of the second torsion spring 14, winds up the first elastic rope 11. At the same time, under the torque of the first torsion spring 10, the baffle 9 gradually rotates and adheres to the frame 5, realizing the automatic storage of the baffle 9.

[0023] The inner surface of the baffle 9 is provided with a light strip 15, and the other end of the baffle 9 is fixedly connected to a second elastic rope 16. The second elastic rope 16 passes through the side wall of the frame 5 and is fixed to the first elastic rope 11. The baffle 9 is connected to the first elastic rope 11 through the second elastic rope 16. When the first elastic rope 11 is wound by the roller 13, the first elastic rope 11 pulls the second elastic rope 16. At the same time, the elastic pulling force of the second elastic rope 16 assists the first torsion spring 10 to rotate and attach the baffle 9 to the frame. On the body 5, the baffle 9 is effectively and tightly attached to the frame 5, thereby ensuring that the frame 5 can smoothly retract into the box 1 through the through hole 6, preventing the other end of the baffle 9 from tilting up and touching the end of the through hole 6, which would cause the baffle 9 to be squeezed and broken; and the inner plate surface of the baffle 9 is provided with a light strip 15, and the light strip 15 and the light column 7 can be controlled to be de-energized separately. According to the user's needs, the light column 7 can be energized or the light column 7 and the light strip 15 can be energized to provide different levels of brightness for the horizontal position.

[0024] A dust suction port 17 is provided at the bottom of the housing 1. A receiving plate 18 is fixedly connected to the dust suction port 17. A filter cover 19 is provided above the receiving plate 18. The upper end of the filter cover 19 is fixed to the inner wall of the housing 1 via a flat plate. An airbag 20 is provided above the flat plate. The air outlet pipe 21 of the airbag 20 passes through the flat plate and the bottom of the housing 1. The exhaust direction of the air outlet pipe 21 is towards the dust suction port 17, and a first-way valve 22 is provided on the air outlet pipe 21. The air extraction pipe 23 of the airbag 20 passes through the flat plate and connects to the inside of the filter cover 19. A second-way valve 24 is provided on the air extraction pipe 23. A push plate 25 is provided above the airbag 20 and is fixed to the end of the rack 4. The exhaust direction of the air outlet pipe 21 is spiral. During the process of the frame 5 retracting into the housing 1 via the rack 4, the push plate 25 on the rack 4 presses against the airbag 20, and the gas inside the airbag 20 passes through... The air is discharged through the exhaust pipe 21, and the gas impacts the area below the dust suction port 17 at the bottom of the housing 1. As the frame extends out of the housing 1, the airbag 20 is no longer compressed. The external air flows and carries the dust at the suction port 17 onto the filter cover 19. The dust adheres to the filter cover 19, and some dust falls onto the receiving plate 18. Gas is then pumped into the airbag 20 through the exhaust pipe 23, and the airbag 20 returns to its initial inflated state. Through the cooperation between the push plate 25, the airbag 20, and the filter cover 19, the dust flocculent material deposited at the bottom of the housing 1 is collected into the housing 1, reducing the harm of dust and flocculent material to the human respiratory tract. The gas impact discharge forms an air vortex, which concentrates and flows the dust and flocculent material together. At the same time, the air vortex can also suck the dust and flocculent material around the housing 1 into the area below the suction port 17, increasing the dust removal area.

[0025] The receiving plate 18 is threaded with a dust collection groove 26, the opening of which faces the filter cover 19. The lower plate of the push plate 25 is provided with a cleaning cover 27, which has symmetrical gaps. An elastic rope 11 passes through the gaps and is slidably connected to the upper end of the filter cover 19 with connecting rods that are symmetrically fixed to the plate. During the process of the push plate 25 squeezing the air bag 20, the push plate 25 pushes the cleaning cover 27 down, and the cleaning cover 27 is placed on the filter cover 19. The lower end of the cleaning cover 27 pushes the dust and flocculent material accumulated on the filter cover 19 into the dust collection groove 26, preventing the dust and flocculent material from floating out of the box 1 again.

[0026] The cleaning cover 27 has multiple protrusions 28 evenly distributed on its lower edge, and the inner wall of the dust collection trough 26 also has multiple layers of protrusions 28. During the downward movement of the cleaning cover 27, the protrusions 28 of the cleaning cover 27 press against the protrusions 28 on the inner wall of the dust collection trough 26, causing them to vibrate and shake the dust on the filter cover 19 and the inner wall of the dust collection trough 26 to the bottom of the dust collection trough 26. At the same time, during the upward movement of the cleaning cover 27, the protrusions 28 of the cleaning cover 27 press against the protrusions 28 on the inner wall of the dust collection trough 26, causing them to vibrate and shake the dust on the filter cover 19 and the inner wall of the dust collection trough 26 to the bottom of the dust collection trough 26 again, so that the dust and flocculent matter are concentrated and fall to the bottom of the dust collection trough 26, preventing the dust and flocculent matter from floating out. After the dust collection trough 26 is full, the dust collection trough 26 is rotated off, cleaned, and then reinstalled on the bottom of the housing 1.

[0027] The airbag 20 is equipped with a reset mechanism; the reset mechanism includes a compression spring 29, a V-shaped rod 30, a push rod 31, and a support plate 32; the V-shaped rod 30 is rotatably connected in the middle, and each end of the V-shaped rod 30 is hinged to a rubber plate 33, which is adhered to the inner top and bottom surfaces of the airbag 20. The inner sides of two adjacent V-shaped rods 30 are connected together by the compression spring 29. The outer side of the V-shaped rod 30 is rotatably connected to the push rod 31, and the end of the push rod 31 is rotatably connected to the support plate 32, which rests against the inner wall of the airbag 20; after the airbag 20 is compressed by the push plate 25, the volume of the airbag 20 gradually shrinks, and the airbag 20 is compressed by the rubber plate 33 into a V-shape. The V-shaped rod 30 compresses the compression spring 29, and at the same time, the gas in the airbag 20 is discharged through the exhaust pipe. After the push plate 25 leaves the airbag 20, the V-shaped rod 30 quickly returns to its initial state under the elastic force of the compression spring 29, and quickly lifts the airbag 20. At the same time, the V-shaped rod 30 pushes the support plate 32 through the push rod 31. The support plate 32 quickly lifts the two sides of the airbag 20, so that the airbag 20 quickly draws in air, accelerates the flow rate of gas into the dust suction port 17, and allows more dust or larger particles to be drawn into the surface of the filter cover 19, thereby enhancing the air suction performance of the airbag 20 and improving the cleaning effect of dust and lint.

[0028] The end of the support plate 32 bends inward toward the airbag 20. The bending of the end of the support plate 32 serves two purposes: first, it prevents the airbag 20 from being crushed and squeezed against the support plate 32, causing the corners of the support plate 32 to rupture the airbag 20, thus protecting the airbag 20; second, the V-shaped rod 30 is pressed against the bent part of the support plate 32, and the reaction force of the support plate 32 pushes the V-shaped rod 30 away. The auxiliary compression spring 29 pushes the V-shaped rod 30 away, accelerating the return of the V-shaped rod 30 to its initial state, thereby accelerating the inflation of the airbag 20 and improving the air extraction performance of the airbag 20.

[0029] Preferably, the filter cover 19 is provided with a plurality of impact rods 191, which are anchor-shaped. One end of each impact rod 191 is fixed to the inner wall of the filter cover 19, and the other ends of the impact rods 191 are close to each other. The antennae on both sides of the impact rods 191 are arc-shaped and close to the inner wall of the filter cover 19. The ends of the antennae are provided with sacs 192, and the sacs 192 have air vents. A push-pull rod 271 is fixed to the top surface of the filter cover. The end of the push-pull rod 271 is T-shaped. The push-pull rod 271 under the cleaning cover collides with the collision rod 191. After the collision rod 191 bends and deforms, it detaches from the end of the push-pull rod 271. Then the collision rod 191 swings up and down, and the antenna collides with the filter cover 19, shaking off the dust from the filter cover 19. At the same time, the capsule 192 at the end of the antenna is squeezed and deformed, and the gas inside the capsule 192 is squeezed out and impacts the filter cover 19, further knocking off the dust on the filter cover 19.

[0030] Example 2: Reference Figure 8 Compared with Embodiment 1, as another embodiment of the present invention, the upper part of the box 1 is provided with a drawer 34, which is slidably connected inside the box 1; by providing a drawer 34 on the box 1, the storage space of the household bedside LED lamp is increased, allowing more items to be placed inside the box 1.

[0031] Working principle: The drive motor 2 moves the rack 4 via the gear 3. The rack 4 moves stably upwards under the constraint of the limiting grooves 8 on both sides, simultaneously pushing the frame 5 through the through hole 6 above the box 1. The lamp post 7 is powered on, emitting light to provide a warm glow for the horizontal space. The lamp post 7 is installed inside the box 1 and rests on the ground, providing strong stability and resisting external impacts to prevent tipping and damage. At night, simply turn off the power to the lamp post 7. During the day, or when there is sufficient light inside the horizontal space, the motor 2 is reversed, and the rack 4 pulls the frame 5 back into the box 1, making the top of the frame 5 flush with the top surface of the box 1. At this time, more items can be placed on the box 1. The items are arranged to provide convenience for the user. During the upward movement of the frame 5, one end of the baffle 9 gradually pulls the first elastic rope 11. At the same time, the baffle 9 rotates around its hinge point, opening the baffle 9. The light emitted by the lamp post 7 shines on the baffle 9, and the light is diffused on the baffle 9, so that the light fully illuminates the horizontal space, providing the user with a more comfortable resting environment. During the process of the frame 5 being pulled back into the box 1, the first elastic rope 11 gradually loosens. The roller 13, under the torque line of the second torsion spring 14, winds up the first elastic rope 11. At the same time, under the torque of the first torsion spring 10, the baffle 9 gradually rotates and attaches to the frame 5, realizing the automatic storage of the baffle 9. The baffle 9 is connected to the first elastic rope 11 by the second elastic rope 16. When the first elastic rope 11 is wound by the roller 13, it pulls the second elastic rope 16. Simultaneously, the elastic tension of the second elastic rope 16 assists the first torsion spring 10 in rotating and attaching the baffle 9 to the frame 5, ensuring the baffle 9 is effectively and tightly attached to the frame 5. This allows the frame 5 to smoothly retract into the housing 1 through the through hole 6, preventing the other end of the baffle 9 from lifting and contacting the end of the through hole 6, which could cause the baffle 9 to break due to compression. Furthermore, a light strip 15 is installed on the inner surface of the baffle 9, and the power to the light strip 15 and the light column 7 can be controlled separately. Depending on the user's needs, the light column 7 can be powered on, or both the light column 7 and the light strip 15 can be powered on, providing different levels of brightness for the horizontal structure. The frame 5 retracts via the rack 4. During the process inside the chamber 1, the push plate 25 on the rack 4 presses against the airbag 20, and the gas inside the airbag 20 is discharged through the air outlet pipe 21. The gas impacts the area below the dust collection port 17 at the bottom of the chamber 1. As the frame extends out of the chamber 1, the airbag 20 is no longer compressed, and the external air flows, carrying the dust at the dust collection port 17 into the filter cover 19. The dust adheres to the filter cover 19, and some dust falls onto the receiving plate 18. Gas is blown into the airbag 20 from the suction pipe 23, and the airbag 20 returns to its initial inflated state. Through the cooperation between the push plate 25, the airbag 20, and the filter cover 19, the dust flocculent material deposited at the bottom of the chamber 1 is collected into the chamber 1, reducing the harm of dust and flocculent material to the human respiratory tract.During the process of the push plate 25 squeezing the airbag 20, the push plate 25 pushes down the cleaning cover 27, which is then placed on the filter cover 19. The lower end of the cleaning cover 27 pushes the dust and lint accumulated on the filter cover 19 into the dust collection trough 26, preventing the dust and lint from floating out of the housing 1 again. During the downward movement of the cleaning cover 27, the protrusions 28 of the cleaning cover 27 squeeze the protrusions 28 on the inner side wall of the dust collection trough 26, causing them to squeeze and vibrate, shaking the dust on the filter cover 19 and the inner side wall of the dust collection trough 26 to the bottom of the dust collection trough 26. At the same time, as the cleaning cover 27 moves upward, the protrusions 28 of the cleaning cover 27 squeeze the dust collection trough 26. The protrusions 28 on the inner wall of the dust collection tank 26 cause a squeezing and vibration, which again shakes the dust on the filter cover 19 and the inner wall of the dust collection tank 26 to the bottom of the dust collection tank 26, so that the dust and flocculent matter are concentrated and fall to the bottom of the dust collection tank 26, preventing the dust and flocculent matter from floating out. After the dust collection tank 26 is full, it is rotated off, cleaned, and then reinstalled on the bottom of the box body 1. After the airbag 20 is squeezed by the push plate 25, the volume of the airbag 20 gradually shrinks. The airbag 20 squeezes the V-shaped rod 30 through the rubber plate 33, and the V-shaped rod 30 squeezes the compression spring 29. At the same time, the gas in the airbag 20 is discharged through the exhaust pipe. After the push plate 25 leaves the airbag 20, the V-shaped rod 30, under the elastic force of the compression spring 29, quickly returns to its initial state and rapidly lifts the airbag 20. Simultaneously, the V-shaped rod 30 pushes the support plate 32 via the push rod 31, causing the support plate 32 to quickly lift both sides of the airbag 20. This allows the airbag 20 to rapidly draw in air, accelerating the flow rate of gas into the suction port 17. This results in more dust or larger particles being drawn onto the surface of the filter cover 19, thus enhancing the suction performance of the airbag 20 and improving the cleaning effect on dust and lint. The curved end of the support plate 32 prevents the airbag 20 from being flattened. The airbag 20 is compressed against the support plate 32, and the corners of the support plate 32 cause the airbag 20 to rupture, thus protecting the airbag 20. Secondly, the V-shaped rod 30 is compressed against the curved part of the support plate 32, and the reaction force of the support plate 32 pushes the V-shaped rod 30 away. The auxiliary compression spring 29 pushes the V-shaped rod 30 away, accelerating its return to its initial state, thereby accelerating the inflation of the airbag 20 and improving its suction performance. The gas impact discharge forms an air vortex, concentrating dust and lint together. Simultaneously, the air vortex also draws dust and lint from around the housing 1 below the suction port 17, increasing the dust removal area.
