Description

Technical Field

[0001] The present invention relates to the technical field of LED ceiling installations, and particularly to an LED ceiling installation device. Background Art

[0002] With the development and growth of commerce, holding large-scale exhibitions has become a way for businesses to communicate and display with customers. At large-scale exhibitions, LED displays are often used as the main technical means for exhibition promotion. LED displays can be divided into inlaid, hanging, wall-mounted, and column-mounted types according to the installation method. To save space at exhibitions, wall-mounted displays are usually used, especially when installed on the ceiling to form an LED ceiling, making the exhibition look more beautiful. However, when installing existing LED ceiling installation devices, after the LED ceiling is lifted by a lifting device, it stops, and the LED ceiling and the ceiling cannot be stably installed, resulting in a risk of the LED ceiling sagging during use.

[0003] A patent with the patent number CN201921030262.7 discloses an LED ceiling installation device. The lifting device of this patent is connected to a housing. The housing is a cuboid cavity structure, and the lower surface of the housing is parallel to the ceiling. An opening is provided on the lower surface of the housing, and the ceiling body is installed inside the housing. With the lifting device, it is more convenient to install the ceiling body at a higher position. Multiple sets of pulleys are provided on the ceiling and the housing to prevent the housing from tilting during the rising process. At the same time, multiple baffles are provided on the rotating shaft to prevent different chains from getting knotted and confused during the winding process. Heat dissipation holes are provided on the upper surface of the housing to prevent the temperature inside the housing from being too high when the ceiling body is working, which affects the normal operation of the ceiling body.

[0004] Although this patent solves the above problems, there is still a problem that the LED ceiling and the ceiling cannot be stably installed, resulting in a risk of the LED ceiling sagging during use. Therefore, an LED ceiling installation device is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an LED ceiling installation device for the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: an LED skylight ceiling device, including a ceiling shell, the top surface of the inner wall of the ceiling shell is fixedly connected to a mounting plate, the lower surface of the mounting plate is fixedly connected to a pulley block, the front side surface of the inner wall of the ceiling shell is rotatably connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to a wire take-up roller, the bottom end of the pulley block is fixedly connected to a skylight mounting frame, the bottom surface of the skylight mounting frame is fixedly connected to a supporting bottom frame, the two sides of the supporting bottom frame are hinged with side panels, the bottom surface of the ceiling shell is fixedly connected to a shell bottom frame, and the small surface of the shell bottom frame is fixedly connected The upper surface of the canopy mounting frame is fixedly connected with a telescopic shell, and the inner surface of the telescopic shell is slidably connected with an inclined telescopic block. The side of the inclined telescopic block close to the pulley block is fixedly connected with a sliding rod. The left side of the ceiling shell is provided with a ventilation device for ventilation and heat dissipation to prevent the LED canopy from being damaged due to the lack of ventilation of the ceiling shell when the LED canopy is used for a long time. The left side of the ceiling shell is provided with a dehumidification device for preventing the LED canopy from short-circuiting due to excessive moisture. A motor is installed at the rear end of the rotating shaft, and The motor is fixedly connected to the rear side of the inner wall of the ceiling shell, the take-up roller and the pulley block are connected by rope transmission, and a spring is arranged between the inclined telescopic block and the telescopic shell. When the LED skylight needs to be installed, the motor is started by the controller, and the motor drives the rotating shaft to rotate clockwise, and the rotating shaft drives the take-up roller to rotate clockwise, and the take-up roller loosens the rope. After the rope is loosened, it drives the skylight installation frame to descend through the operation of the pulley block. The staff inserts the LED skylight into the skylight installation frame, and then lifts the side panel and closes it with the skylight installation frame, so as to quickly install the LED skylight and improve the installation efficiency. After closing the side panel, The motor is started again through the controller, and the motor is controlled to drive the rotating shaft and the take-up roller to rotate counterclockwise. When the take-up roller rotates counterclockwise, the rope can be reeled in. The reeling of the rope causes the pulley group to operate and drive the awning installation frame to rise. When the awning installation frame rises, it drives the telescopic shell and the inclined telescopic block to rise. When the upper inclined surface of the inclined telescopic block conflicts with the lower inclined surface of the inclined conflicting block, the inclined telescopic block slides and contracts toward the inside of the telescopic shell. When the inclined telescopic block moves between the bottom frame of the shell and the splint, the spring drives the inclined telescopic block to pop out and insert it between the bottom frame of the shell and the splint, so that the awning installation frame is stuck at the bottom of the ceiling shell.

[0007] Preferably, the ventilation device includes a ventilation chamber, a first filter screen, and a sealing sliding member. The ventilation chamber is fixedly connected to the left side surface of the ceiling outer shell. The first filter screen is fixedly connected to the inner wall of the ventilation chamber. The sealing sliding member is slidably connected to the left side surface of the inner wall of the ceiling outer shell. The ventilation device further includes a limiting sliding column, an L-shaped slotted pull plate, a folding connecting member, an L-shaped lifting rod, a connecting ring, and a jacking plate. The limiting sliding column is fixedly connected to the front and rear sides of the inner wall of the ceiling outer shell. The L-shaped slotted pull plate is slidably connected to the outer surface of the limiting sliding column. The folding connecting member is fixedly connected to the right side surface of the sealing sliding member. The L-shaped lifting rod is slidably connected to the left side of the bottom of the ceiling outer shell. The connecting ring is fixedly connected to the outer surface of the L-shaped lifting rod. The jacking plate is fixedly connected to the left side surface of the sky curtain installation frame. The sealing sliding member is slidably connected to the outer surface of the limiting sliding column. A convex block one is provided on the right side surface of the sealing sliding member, and the folding connecting member is clamped with the convex block one. A spring is provided between the connecting ring and the lower surface of the inner wall of the ceiling outer shell. The L-shaped lifting rod is slidably connected to the inner surface of the L-shaped slotted pull plate. A convex block two is provided at the right end of the L-shaped slotted pull plate, and the folding connecting member is clamped with the convex block two. When the LED sky curtain is used for a long time, it is prone to heat generation. When the heat cannot be dissipated, it is easy to cause the LED sky curtain to be damaged due to overheating. When the heat in the ceiling outer shell is too high, the heat will be conducted out of the ceiling outer shell through the ventilation chamber to dissipate the heat. After the LED sky curtain is installed, the pulley group drives the sky curtain installation frame to rise. While the sky curtain installation frame rises, it drives the jacking plate to rise. When the jacking plate touches the L-shaped lifting rod, it drives the L-shaped lifting rod to rise. During the rising process of the L-shaped lifting rod, through the guidance of the inclined slot opened in the L-shaped slotted pull plate, it drives the L-shaped slotted pull plate to slide forward on the limiting sliding column. The L-shaped slotted pull plate then drives the folding connecting member clamped with it to move forward. The folding connecting member clamped with the L-shaped slotted pull plate drives multiple groups of sealing sliding members and folding connecting members to move forward and unfold, so that a gap appears between the ventilation chamber and the ceiling outer shell, thereby enabling ventilation. When the sky curtain installation frame descends, the spring pulls the L-shaped lifting rod to descend. The descent of the L-shaped lifting rod drives it to move backward through the guidance of the inclined slot opened on the L-shaped slotted pull plate. The backward movement of the L-shaped slotted pull plate drives multiple groups of folding connecting members and sealing sliding members to move backward and close.

[0008] Preferably, the dehumidifying device includes a second filter screen, a feeding frame, and a discharging frame. The second filter screen is fixedly connected to the inner wall of the ventilation chamber. The feeding frame is fixedly connected to the rear side of the ventilation chamber. The discharging frame is fixedly connected to the lower surface of the ventilation chamber. The dehumidifying device further includes an L-shaped pull rod, a sliding push block, a discharging push plate, a clamping shaft, a U-shaped pull rod, and a feeding baffle. The L-shaped pull rod is fixedly connected to the left side surface of the L-shaped inclined groove pull plate. The sliding push block is slidably connected to the left side surface of the L-shaped pull rod. The discharging push plate is slidably connected to the inner surface of the ventilation chamber. The clamping shaft is fixedly connected to the rear end of the right side surface of the L-shaped pull rod. The feeding baffle is slidably connected to the inner surface of the ventilation chamber. The U-shaped pull rod is fixedly connected to the front side surface of the feeding baffle. An inlet is formed on the rear side surface of the ventilation chamber, and a discharge port is formed at the bottom of the ventilation chamber. A first chute is formed on the left side surface of the ceiling housing, and the L-shaped pull rod is slidably connected to the inner surface of the first chute. A second chute is formed on the left side surface of the L-shaped pull rod, and the sliding push block is slidably connected to the inner surface of the second chute. A spring is disposed between the rear side surface of the sliding push block and the L-shaped pull rod. The clamping shaft is slidably connected to the inner surface of the U-shaped pull rod. A notch is formed at the bottom of the feeding baffle. A spring is disposed between the front side surface of the discharging push plate and the front side surface of the inner wall of the ventilation chamber. When the ventilation chamber is ventilated, solid desiccant can be put into the ventilation chamber through the feeding frame. When the L-shaped inclined groove pull plate moves forward, it drives the L-shaped pull rod to slide forward. The L-shaped pull rod drives the sliding push block to move forward. After the sliding push block touches the discharging push plate, it drives the discharging push plate to move forward. After the discharging push plate touches the front side surface of the inner wall of the ventilation chamber, the discharge port is exposed. At this time, the old solid desiccant that has absorbed moisture in the ventilation chamber can be discharged from the discharge port. When the discharging push plate touches the front side surface of the inner wall of the ventilation chamber, the L-shaped pull rod continues to move forward. At this time, the sliding push block slides in the second chute to prevent the L-shaped pull rod from being obstructed by the discharging push plate when moving. When the L-shaped pull rod drives the clamping shaft to move to the front end of the U-shaped pull rod, it drives the U-shaped pull rod and the feeding baffle to slide forward. At this time, the new solid dryer enters the ventilation chamber from the inlet, then enters the space between the feeding baffle and the discharging push plate through the notch formed on the feeding baffle, and then the L-shaped pull rod drives the sliding push block to move backward. After the discharging push plate loses the contact of the sliding push block, the spring disposed between the discharging push plate and the ventilation chamber drives it to reset to block the discharge port.

[0009] The present invention adopts the above technical solutions and can bring the following beneficial effects:

[0010] 1. For this LED sky curtain ceiling device, when the pulley block operates to drive the sky curtain installation frame to descend, it is convenient for workers to install the LED sky curtain on the sky curtain installation frame. There is no need for workers to install the LED sky curtain at a high place through tools such as scaffolding, which improves the safety of installing the LED sky curtain on the ceiling shell. The spring drives the inclined telescopic block to pop out and insert between the bottom frame of the shell and the clamping plate, so that the sky curtain installation frame is stuck at the bottom of the ceiling shell, quickly realizing the fixation of the sky curtain installation frame and the ceiling shell, and further improving the installation efficiency.

[0011] 2. For this LED sky curtain ceiling device, when the heat in the ceiling shell is too high, the heat will be conducted out of the ceiling shell through the ventilation chamber to dissipate the heat, preventing the LED sky curtain from being damaged due to overheating. After the LED sky curtain is installed, a radiator can be connected through the ventilation chamber to further accelerate the heat dissipation speed and extend the service life of the LED sky curtain. When the L-shaped chute pull plate moves backward, it drives multiple sets of folding connectors and closed sliding parts to move backward and close, preventing dust from entering the ventilation chamber from the ceiling shell during installation and avoiding blockage of the ventilation chamber, further improving the ventilation effect.

[0012] 3. For this LED sky curtain ceiling device, solid desiccant is put into the ventilation chamber through the feeding frame. At this time, when the air contacts the solid desiccant, the moisture in the air decreases, preventing moisture from penetrating into the LED sky curtain and causing a short circuit of the LED sky curtain in overly humid weather. The new solid dryer enters the ventilation chamber from the feeding port, then enters between the feeding baffle and the discharging push plate through the slot opened on the feeding baffle. Then the L-shaped pull rod drives the sliding push block to move backward. After the discharging push plate loses the resistance of the sliding push block, the spring arranged between the discharging push plate and the ventilation chamber drives it to reset and block the discharging port, thus realizing the replacement of the solid desiccant and further improving the dehumidification effect.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 11, an embodiment of the present invention is: an LED sky curtain ceiling device, including a ceiling outer shell 1, the top surface of the inner wall of the ceiling outer shell 1 is fixedly connected with a mounting plate 2, the lower surface of the mounting plate 2 is fixedly connected with a pulley group 3, the front side surface of the inner wall of the ceiling outer shell 1 is rotatably connected with a rotating shaft 4, the outer surface of the rotating shaft 4 is fixedly connected with a wire winding roller 5, the bottom end of the pulley group 3 is fixedly connected with a sky curtain mounting frame 6, the bottom surface of the sky curtain mounting frame 6 is fixedly connected with a support bottom frame 61, both sides of the support bottom frame 61 are hinged with side plates 62, the bottom surface of the ceiling outer shell 1 is fixedly connected with an outer shell bottom frame 63, the small surface of the outer shell bottom frame 63 is fixedly connected with an inclined surface abutting block 64, the front and rear sides of the inner wall of the ceiling outer shell 1 are fixedly connected with clamping plates 65, the upper surface of the sky curtain mounting frame 6 is fixedly connected with a telescopic outer shell 66, the inner surface of the telescopic outer shell 66 is slidably connected with an inclined surface telescopic clamping block 67, one side of the inclined surface telescopic clamping block 67 close to the pulley group 3 is fixedly connected with a sliding rod 68, the operation of the pulley group 3 drives the sky curtain mounting frame 6 to descend, at this time, it is convenient for workers to install the LED sky curtain on the sky curtain mounting frame 6, without the need for workers to install the LED sky curtain at a high place through tools such as scaffolding, which improves the safety of installing the LED sky curtain on the ceiling outer shell 1. A ventilation device 7 for ventilation and heat dissipation to prevent the LED sky curtain from being damaged due to non-ventilation of the ceiling outer shell 1 during long-term use is arranged on the left side of the ceiling outer shell 1. A dehumidification device 8 for preventing the LED sky curtain from short-circuiting due to excessive moisture is arranged on the left side of the ceiling outer shell 1. A motor is installed at the rear end of the rotating shaft 4, and the motor is fixedly connected with the rear side surface of the inner wall of the ceiling outer shell 1. The wire winding roller 5 and the pulley group 3 are connected by a rope. A spring is arranged between the inclined surface telescopic clamping block 67 and the telescopic outer shell 66. The spring drives the inclined surface telescopic clamping block 67 to pop out and insert between the outer shell bottom frame 63 and the clamping plate 65, so that the sky curtain mounting frame 6 is clamped at the bottom of the ceiling outer shell 1, quickly realizing the fixation of the sky curtain mounting frame 6 and the ceiling outer shell 1, and further improving the installation efficiency.

[0027] Working principle: When installing the LED sky curtain, start the motor through the controller. The motor drives the rotating shaft 4 to rotate clockwise. The rotating shaft 4 drives the wire winding roller 5 to rotate clockwise. The wire winding roller 5 relaxes the rope. After the rope is relaxed, it drives the sky curtain installation frame 6 to descend through the pulley block 3. At this time, it is convenient for the staff to install the LED sky curtain on the sky curtain installation frame 6, without the need for the staff to install the LED sky curtain at a high place through tools such as scaffolding, improving the safety of installing the LED sky curtain on the ceiling shell 1. The staff inserts the LED sky curtain into the sky curtain installation frame 6, and then lifts the side plate 62 to close it with the sky curtain installation frame 6, thus quickly installing the LED sky curtain and improving the installation efficiency. After closing the side plate 62, start the motor again through the controller and control the motor to drive the rotating shaft 4 and the wire winding roller 5 to rotate counterclockwise. When the wire winding roller 5 rotates counterclockwise, it can wind up the rope. The winding of the rope makes the pulley block 3 operate to drive the sky curtain installation frame 6 to rise. When the sky curtain installation frame rises, it drives the telescopic shell 66 and the inclined telescopic clamping block 67 to rise. When the upper inclined surface of the inclined telescopic clamping block 67 abuts against the lower inclined surface of the inclined surface abutting block 64, the inclined telescopic clamping block 67 slides and contracts inwardly into the telescopic shell 66. When the inclined telescopic clamping block 67 moves between the bottom frame 63 of the shell and the clamping plate 65, the spring drives the inclined telescopic clamping block 67 to pop out and insert between the bottom frame 63 of the shell and the clamping plate 65, so that the sky curtain installation frame 6 is clamped at the bottom of the ceiling shell 1, quickly realizing the fixation of the sky curtain installation frame 6 and the ceiling shell 1, and further improving the installation efficiency.

[0028] Please refer to Figures 1 - 11, on the basis of the above embodiments, in another embodiment of the present invention, the ventilation device 7 includes a ventilation chamber 71, a first filter screen 72, and a sealing sliding member 73. The ventilation chamber 71 is fixedly connected to the left side surface of the ceiling housing 1, the first filter screen 72 is fixedly connected to the inner wall of the ventilation chamber 71, and the sealing sliding member 73 is slidably connected to the left side surface of the inner wall of the ceiling housing 1. When the heat in the ceiling housing 1 is too high, the heat will be conducted out of the ceiling housing 1 through the ventilation chamber 71, so that the heat dissipates, preventing the LED sky curtain from being damaged due to overheating. And after the LED sky curtain is installed, a radiator can be connected through the ventilation chamber 71 to further accelerate the heat dissipation speed and extend the service life of the LED sky curtain. The ventilation device 7 further includes a limit sliding column 74, an L-shaped inclined groove pull plate 75, a folding connecting member 76, an L-shaped lifting rod 77, a connecting ring 78, and a jacking plate 79. The limit sliding column 74 is fixedly connected to the front and rear sides of the inner wall of the ceiling housing 1, the L-shaped inclined groove pull plate 75 is slidably connected to the outer surface of the limit sliding column 74, the folding connecting member 76 is fixedly connected to the right side surface of the sealing sliding member 73, the L-shaped lifting rod 77 is slidably connected to the left side of the bottom of the ceiling housing 1, the connecting ring 78 is fixedly connected to the outer surface of the L-shaped lifting rod 77, and the jacking plate 79 is fixedly connected to the left side surface of the sky curtain installation frame 6. The sealing sliding member 73 is slidably connected to the outer surface of the limit sliding column 74. A first convex block is provided on the right side surface of the sealing sliding member 73, and the folding connecting member 76 is clamped with the first convex block. A spring is provided between the connecting ring 78 and the lower surface of the inner wall of the ceiling housing 1. The L-shaped lifting rod 77 is slidably connected to the inner surface of the L-shaped inclined groove pull plate 75. A second convex block is provided at the right end of the L-shaped inclined groove pull plate 75, and the folding connecting member 76 is clamped with the second convex block. When the L-shaped inclined groove pull plate 75 moves backward, it drives a plurality of folding connecting members 76 and the sealing sliding member 73 to move backward and close, preventing dust from entering the ventilation chamber 71 from the ceiling housing 1 during installation, avoiding blockage of the ventilation chamber 71, and further improving the ventilation effect.

[0029] Working principle: When the LED sky curtain is used for a long time, it is prone to heat up. When the heat cannot dissipate, it is easy to cause the LED sky curtain to be damaged due to overheating. When the heat in the ceiling shell 1 is too high, the heat will be conducted out of the ceiling shell 1 through the ventilation chamber 71, so that the heat dissipates, preventing the LED sky curtain from being damaged due to overheating. And after the LED sky curtain is installed, a radiator can be connected through the ventilation chamber 71 to further accelerate the heat dissipation speed and extend the service life of the LED sky curtain. When the LED sky curtain is installed, the pulley group 3 drives the sky curtain installation frame 6 to rise. While the sky curtain installation frame 6 rises, it drives the jacking plate 79 to rise. When the jacking plate 79 touches the L-shaped lifting rod 77, it drives the L-shaped lifting rod 77 to rise. During the rising process of the L-shaped lifting rod 77, through the guidance of the inclined groove opened in the L-shaped inclined groove plate 75, it drives the L-shaped inclined groove plate 75 to slide forward on the limit sliding column 74. The L-shaped inclined groove plate 75 then drives the folding connector 76 clamped with it to move forward. The folding connector 76 clamped with the L-shaped inclined groove plate 75 then drives multiple groups of closed sliding members 73 and the folding connector 76 to move forward and unfold, so that a gap appears between the ventilation chamber 71 and the ceiling shell 1, thus enabling ventilation. When the sky curtain installation frame 6 descends, the spring pulls the L-shaped lifting rod 77 to descend. The descent of the L-shaped lifting rod 77 causes it to move backward through the guidance of the inclined groove opened on the L-shaped inclined groove plate 75. The backward movement of the L-shaped inclined groove plate 75 drives multiple groups of folding connectors 76 and the closed sliding members 73 to move backward and close, preventing dust from entering the ventilation chamber 71 from the ceiling shell 1 during installation, avoiding blockage of the ventilation chamber 71, and further improving the ventilation effect.

[0030] Please refer to Figures 1 - 11On the basis of the above embodiment, in another embodiment of the present invention, the dehumidification device 8 includes a second filter 81, a feed frame 82, and a discharge frame 83. The second filter 81 is fixedly connected to the inner wall of the ventilation chamber 71, the feed frame 82 is fixedly connected to the rear side of the ventilation chamber 71, and the discharge frame 83 is fixedly connected to the lower surface of the ventilation chamber 71. The solid desiccant is put into the ventilation chamber 71 through the feed frame 82. At this time, when the air contacts the solid desiccant, the moisture in the air is reduced, preventing moisture from penetrating into the LED skylight when the weather is too humid. The dehumidification device 8 also includes an L-shaped pull rod 84, a sliding push block 85, a discharge push plate 86, a clamping shaft 87, a U-shaped pull rod 88, and a feed baffle 89. The L-shaped pull rod 84 is fixedly connected to the left side of the L-shaped inclined groove pull plate 75, the sliding push block 85 is slidably connected to the left side of the L-shaped pull rod 84, the discharge push plate 86 is slidably connected to the inner surface of the ventilation chamber 71, the clamping shaft 87 is fixedly connected to the rear end of the right side of the L-shaped pull rod 84, the feed baffle 89 is slidably connected to the inner surface of the ventilation chamber 71, and the U-shaped pull rod 88 is fixed.

A spring is arranged between the front side surface and the front side surface of the inner wall of the ventilation chamber 71. The new solid dryer enters the ventilation chamber 71 from the feed port, and then enters between the feed baffle 89 and the discharge push plate 86 from the groove opened on the feed baffle 89. Then the L-shaped pull rod 84 drives the sliding push block 85 to move backward. After the discharge push plate 86 loses the resistance of the sliding push block 85, the spring arranged between the discharge push plate 86 and the ventilation chamber 71 drives it to reset and block the discharge port, thereby realizing the replacement of the solid desiccant and further improving the dehumidification effect.

[0031] Working principle: When the ventilation chamber 71 is ventilated, solid desiccant can be put into the ventilation chamber 71 through the feeding frame 82. At this time, when the air contacts the solid desiccant, the moisture in the air decreases, preventing moisture from penetrating into the LED sky curtain and causing a short circuit in the LED sky curtain when the weather is too humid. When the L-shaped chute pull plate 75 moves forward, it drives the L-shaped pull rod 84 to slide forward. The L-shaped pull rod 84 drives the sliding push block 85 to move forward. After the sliding push block 85 touches the discharge push plate 86, it drives the discharge push plate 86 to move forward. When the discharge push plate 86 touches the front side of the inner wall of the ventilation chamber 71, the discharge port is exposed. At this time, the old solid desiccant that has absorbed moisture in the ventilation chamber 71 can be discharged from the discharge port. When the discharge push plate 86 touches the front side of the inner wall of the ventilation chamber 71, the L-shaped pull rod 84 continues to move forward. At this time, the sliding push block 85 slides in the second chute to prevent the L-shaped pull rod 84 from being blocked by the discharge push plate 86 when moving. When the L-shaped pull rod 84 drives the clamping shaft 87 to move to the front end of the U-shaped pull rod 88, it drives the U-shaped pull rod 88 and the feeding baffle 89 to slide forward. At this time, the new solid dryer enters the ventilation chamber 71 from the feeding port, and then enters the space between the feeding baffle 89 and the discharge push plate 86 through the slot opened on the feeding baffle 89. Then the L-shaped pull rod 84 drives the sliding push block 85 to move backward. After the discharge push plate 86 loses the contact of the sliding push block 85, the spring provided between the discharge push plate 86 and the ventilation chamber 71 drives it to reset and block the discharge port, thus realizing the replacement of the solid desiccant and further improving the dehumidification effect.

[0032] The present invention provides an LED sky curtain ceiling device. There are many methods and ways to specifically implement this technical solution.
