Description

Technical Field

[0001] The present application relates to the field of air-conditioning purification technology, and in particular to an air inlet structure of a hospital air-conditioning system with a disinfection function. Background Art

[0002] A central air conditioner is an air-conditioning system that centrally processes air and realizes temperature control adjustment in multiple areas. Through a unified main unit, pipelines and terminal equipment, it provides functions such as refrigeration, heating, and ventilation for large buildings such as shopping malls, railway stations, hospitals, etc. Among them, hospitals are places where pathogens are highly concentrated. To avoid the spread of viruses through the central air-conditioning system, it is necessary to regularly disinfect the inside of the central air conditioner. Most hospitals often use ultraviolet irradiation for disinfection. The principle is to use the wavelength of ultraviolet light to destroy the molecular structure of pathogens, thereby achieving the effect of disinfection and sterilization. The effective disinfection area is 1.5 - 2m around the ultraviolet lamp tube.

[0003] The Chinese utility model patent with the authorization publication number CN221611545U discloses an ultraviolet disinfection device for a terminal building central air-conditioning system, which includes an air-conditioning unit. A filter screen and an ultraviolet disinfection lamp are installed in the air-conditioning unit. After outdoor fresh air and indoor return air are mixed, they are sent in after being filtered by the filter screen of the air-conditioning unit, and the ultraviolet disinfection lamp continuously disinfects the filter screen.

[0004] For the above technology, the inventor found that the ultraviolet disinfection lamp has a disinfection effect on the area it irradiates. Therefore, it is necessary to regularly wipe its surface with alcohol to avoid dust accumulation affecting its irradiation range and intensity, and ensure that the disinfection effect will not be affected. However, in the above solution, the ultraviolet disinfection lamp is installed inside the air-conditioning unit, and it is quite troublesome to clean, and it is impossible to often wipe its surface, resulting in the disinfection effect being affected. Summary of the Invention

[0005] In order to facilitate wiping the surface of the ultraviolet disinfection lamp inside the air-conditioning unit and ensure the disinfection effect of the ultraviolet disinfection lamp on the air-conditioning filter screen, the present application provides an air inlet structure of a hospital air-conditioning system with a disinfection function.

[0006] An air inlet structure of a hospital air-conditioning system with a disinfection function provided by the present application adopts the following technical solution:

[0007] An air inlet structure of a hospital air-conditioning system with a disinfection function includes a mounting sleeve detachably connected to the air inlet. A louver curtain and a filter screen are arranged inside the mounting sleeve. A winding assembly is arranged inside the mounting sleeve, and the winding assembly is used for winding the louver curtain and the filter screen. A cylinder and a first fixing plate are arranged inside the ceiling. The cylinder is used to drive the first fixing plate to slide inside the mounting sleeve. A lifting assembly is arranged inside the first fixing plate, and an ultraviolet disinfection lamp is arranged on the lifting assembly.

[0008] By adopting the above technical solution, when the central air conditioner is working normally, the blinds and the filter are in an extended state, the air inlet is closed and filtered, and the ultraviolet disinfection lamp is located in the ceiling to disinfect the filter;

[0009] When the ultraviolet disinfection lamp needs to be wiped and cleaned, the winding assembly is started, and the winding assembly drives the blinds and one end of the filter to be rolled up, so that the air inlet is opened. At this time, the cylinder extends to drive the first fixed plate to extend out of the air inlet, and the lifting assembly is started to drive the ultraviolet disinfection lamp to descend to a height that is convenient for wiping, so as to facilitate the regular wiping and cleaning of the ultraviolet disinfection lamp, and ensure the disinfection effect of the ultraviolet disinfection lamp on the air conditioner filter;

[0010] After wiping is completed, the lifting assembly drives the ultraviolet disinfection lamp to rise and reset, and the cylinder contracts to drive the first fixed plate back into the ceiling, so that the ultraviolet disinfection lamp returns to the air-conditioning unit, and then the blinds and filter are extended to close the air inlet again.

[0011] Optionally, the winding assembly includes a rotating shaft, one end of the venetian blind and the filter screen is wound on the rotating shaft, and the other end is slidably connected to the mounting sleeve, the mounting sleeve is rotatably connected with a rotating rod, the rotating rod and the rotating shaft are axially parallel, and pulleys are coaxially arranged on the rotating rod and the rotating shaft, and the two pulleys are connected by belts, the rotating rod is located on the side of the filter screen facing the ceiling and is spaced apart from it, a gear is coaxially arranged on the rotating rod, a rack is provided on the first fixed plate, the rack is used to mesh with the gear, and when the ultraviolet disinfection lamp disinfects the filter screen, the rack is located on the side of the gear away from the filter screen.

[0012] By adopting the above technical solution, since the gear and the filter are arranged at intervals, and the rack is located on the side of the gear away from the filter, when the cylinder drives the first fixed plate to move until the rack begins to mesh with the gear, the venetian blind and the filter begin to roll up, thereby opening the air inlet; when the first fixed plate moves to the air inlet, the venetian blind and the filter are just rolled up to the space of the opened air inlet so that the first fixed plate can pass through, and at this time the gear is also separated from the rack, and the open space of the air inlet is fixed by the first fixed plate, and the first fixed plate is gradually extended as the telescopic shaft of the cylinder is extended, thereby extending the ultraviolet disinfection lamp from the air inlet;

[0013] Through the cooperation of gears and racks, the blinds and the filter can be rolled up at the same time when the first fixed plate is moved to the air inlet. That is, the air inlet is opened before the ultraviolet disinfection lamp reaches the air inlet. One cylinder can be used to move the ultraviolet disinfection lamp and open the air inlet at the same time, which is not only convenient to use but also saves resources.

[0014] Optionally, one end of the louver and the filter net away from the rotating shaft are fixedly connected through a connecting plate. Two springs are connected between the connecting plate and the inner wall of the mounting sleeve. The first fixing plate is located between the two springs.

[0015] By adopting the above technical solution, after the ultraviolet disinfection lamp is cleaned, first start the lifting component to reset the ultraviolet disinfection lamp, and then start the cylinder. The contraction of the cylinder telescopic rod drives the first fixing plate to retract into the ceiling. As the first fixing plate moves, the rack contacts the gear, and the rack drives the gear to rotate in the reverse direction, thereby lowering the louver and the filter net. When the first fixing plate completely enters the ceiling, due to the pulling force of the spring, the lowered louver and filter net are stretched out, thereby closing the air inlet, and there is no need to manually close it, which facilitates the use.

[0016] Optionally, a third fixing plate is arranged inside the first fixing plate. The lifting component includes a lifting motor arranged on the third fixing plate. A lifting rotating shaft is rotatably connected to the third fixing plate. The lifting motor is used to drive the lifting rotating shaft to rotate. Two suspension ropes are wound on the lifting rotating shaft. The two suspension ropes are used to fix the ultraviolet disinfection lamp.

[0017] By adopting the above technical solution, after the ultraviolet disinfection lamp extends out of the air inlet, start the lifting motor. The lifting motor drives the lifting shaft to rotate, thereby lowering the suspension ropes and lowering the ultraviolet disinfection lamp to a height convenient for wiping, so as to facilitate wiping and cleaning of it.

[0018] Optionally, a second fixing plate is arranged inside the first fixing plate. The second fixing plate is U-shaped. Swing rods are rotatably connected to both side plates of the second fixing plate. The rotation centers of the two swing rods are coaxially arranged. The third fixing plate is fixedly connected between the two swing rods. A swing motor is arranged on the second fixing plate. The swing motor is used to drive the swing rods to swing reciprocally.

[0019] By adopting the above technical solution, when the ultraviolet disinfection lamp extends into the room, the indoor space can be disinfected at this time. At this time, start the swing motor. The swing motor drives the swing rods to swing reciprocally, thereby driving the third fixing plate to swing reciprocally. The third fixing plate drives the ultraviolet disinfection lamp to swing back and forth through the suspension ropes, and a large-range dynamic disinfection of the indoor space can be realized, expanding the disinfection range; at the same time, it can cooperate with the lifting component to move the ultraviolet disinfection lamp to different heights to realize disinfection in different height ranges, improving the disinfection effect on the entire indoor space.

[0020] Optionally, a swing main shaft is rotatably connected to the side plate of the second fixed plate, and a first connecting rod is rotatably connected to the bottom plate of the second fixed plate. The swing main shaft and the first connecting rod are axially perpendicular to each other, and the two are rotatably connected through a bevel gear set. The swing main shaft is axially parallel to the axial direction of the lifting shaft. The swing motor is used to drive the swing main shaft to rotate. The other end of the first connecting rod is fixedly connected to the second connecting rod, and the length direction of the second connecting rod is perpendicular to the length direction of the first connecting rod. The other end of the second connecting rod is rotatably connected to a third connecting rod, and the third connecting rod is axially parallel to the axial direction of the first connecting rod. A fixing ring is provided on the third connecting rod, and the fixing ring is coaxially sleeved on the swing secondary shaft.

[0021] By adopting the above technical solution, the swing motor drives the swing main shaft to rotate, the swing main shaft drives the first connecting rod to rotate through the bevel gear set, the first connecting rod drives the second connecting rod to rotate with the first connecting rod as the center, the second connecting rod drives the swing secondary shaft to swing back and forth with the rotation center of the two swing rods as the center through the third connecting rod, and drives the third fixed plate to swing back and forth, thereby driving the ultraviolet disinfection lamp to swing back and forth through the suspension rope, thereby performing large-scale dynamic disinfection in the room.

[0022] Optionally, the first fixing plate is configured to be U-shaped, and a flip motor is disposed in the first fixing plate, and the flip motor is used to drive the second fixing plate to rotate ninety degrees.

[0023] By adopting the above technical scheme, since the opening positions of air inlets in different indoor spaces are different, they may be opened vertically or horizontally. If the air inlet is opened horizontally, the venetian blinds and the filter are both installed horizontally, and the first fixed plate is located directly above the air inlet. At this time, the cylinder can directly send out the ultraviolet disinfection lamp vertically; if the air inlet is opened vertically, the venetian blinds and the filter are both installed vertically, and the first fixed plate is located directly behind the air inlet in a horizontal state. When the first fixed plate extends out of the air inlet, the flip motor is started at this time to rotate the second fixed plate downward ninety degrees, so that the swing component is set vertically, which can always keep driving the ultraviolet disinfection lamp to swing back and forth, thereby expanding the scope of application of the device, which can be applied to both vertical and horizontal air inlet forms.

[0024] Optionally, a flip main shaft and a flip secondary shaft are rotatably connected between the two side plates of the first fixed plate, the two axes are parallel, and the flip secondary shaft is located on the side of the flip main shaft away from the cylinder. A flip motor is arranged in the first fixed plate, and the flip motor is used to drive the flip main shaft to rotate. Flip pulleys are coaxially arranged on the flip main shaft and the flip secondary shaft, and the two flip pulleys are connected by belts. A connecting seat is fixedly connected to the flip secondary shaft, and the second fixed plate is fixedly connected to the connecting seat.

[0025] By adopting the above technical solution, when the second fixed plate is flipped, the flipping motor is started. The flipping motor drives the flipping main shaft to rotate. The flipping main shaft drives the flipping sub-shaft to rotate 90 degrees through the flipping pulley, so as to drive the second fixed plate to rotate 90 degrees through the connecting seat, completing the adjustment of the direction of the swinging assembly.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When it is necessary to wipe and clean the ultraviolet disinfection lamp, the winding assembly is started. The winding assembly drives one end of the louver curtain and the filter screen to wind up, opening the air inlet. At this time, the air cylinder extends to drive the first fixed plate to extend out of the air inlet. The lifting assembly is started to drive the ultraviolet disinfection lamp to descend to a height convenient for wiping, so as to facilitate the regular wiping and cleaning of the ultraviolet disinfection lamp, ensuring the disinfection effect of the ultraviolet disinfection lamp on the air conditioner filter screen;

[0028] 2. Through the cooperation of the gear and the rack, during the process of moving the first fixed plate to the air inlet, the winding of the louver curtain and the filter screen can be completed simultaneously, that is, before the ultraviolet disinfection lamp reaches the air inlet, the air inlet has been opened. Using one air cylinder can simultaneously complete the movement of the ultraviolet disinfection lamp and the opening of the air inlet, which is not only convenient to use but also saves resources;

[0029] 3. When the ultraviolet disinfection lamp extends into the room, the indoor space can be disinfected at this time. The swinging motor is started, and the swinging motor drives the swinging rod to swing reciprocally, thereby driving the third fixed plate to swing reciprocally. The third fixed plate drives the ultraviolet disinfection lamp to swing back and forth through the suspension rope, realizing large-range dynamic disinfection of the indoor space and expanding the disinfection range; at the same time, it can cooperate with the lifting assembly to move the ultraviolet disinfection lamp to different heights to achieve disinfection in different height ranges, improving the disinfection effect on the entire indoor space.

Detailed implementation manners

[0036] Central air conditioners are generally installed in the indoor ceiling. An air inlet and an air outlet are provided on the ceiling. The opening positions of the air outlets vary due to different interior room decoration layouts, but generally they are vertically opened on the side of the ceiling or horizontally opened on the bottom surface of the ceiling. An air outlet grille and a filter screen need to be installed at the air outlet to prevent dust and other sundries from entering the interior of the air conditioner unit.

[0037] The following Figures 1-5 further elaborates on the present application in detail.

[0038] The embodiment of the present application discloses an air inlet structure of a hospital air conditioning system with a disinfection function.

[0039] Referring to Figure 1 and Figure 2, An air intake structure of a hospital air conditioning system with a disinfection function includes an installation sleeve 21, which can be connected to the air inlet 1 by bolts. At one open end of the installation sleeve 21, there are louver curtains 31 and a filter screen 32. A winding assembly 4 is arranged inside the installation sleeve 21 for winding the louver curtains 31 and the filter screen 32. Inside the ceiling, there is a cylinder 51 and a first fixing plate 61. The cylinder 51 is used to drive the first fixing plate 61 to slide axially along the installation sleeve 21. A flipping assembly 62 is arranged inside the first fixing plate 61, and a second fixing plate 71 is arranged on the flipping assembly 62. The flipping assembly 62 is used to drive the second fixing plate 71 to rotate. A swinging assembly 72 is arranged inside the second fixing plate 71, and a third fixing plate 81 is arranged on the swinging assembly 72. The swinging assembly 72 is used to drive the third fixing plate 81 to swing reciprocally. An elevating assembly 82 is arranged inside the third fixing plate 81, and an ultraviolet disinfection lamp 9 is arranged at the bottom of the elevating assembly 82. The elevating assembly 82 is used to drive the ultraviolet disinfection lamp 9 to move up and down.

[0040] During the daily operation of the central air conditioner, the louver curtains 31 and the filter screen 32 are both in the extended state to close and filter the air inlet 1. The ultraviolet disinfection lamp 9 is located inside the ceiling to disinfect the filter screen 32. When it is necessary to wipe and clean the ultraviolet disinfection lamp 9, the winding assembly 4 is started. The winding assembly 4 drives one end of the louver curtains 31 and the filter screen 32 to wind, opening the air inlet 1. At this time, the cylinder 51 extends to drive the first fixing plate 61 to extend out of the air inlet 1. The elevating assembly 82 is started to drive the ultraviolet disinfection lamp 9 to descend to a height convenient for wiping, thus facilitating the regular wiping and cleaning of the ultraviolet disinfection lamp 9. After wiping, the elevating assembly 82 drives the ultraviolet disinfection lamp 9 to rise and reset. The cylinder 51 contracts to drive the first fixing plate 61 to return to the inside of the ceiling, making the ultraviolet disinfection lamp 9 return to the air conditioner unit. Then, the louver curtains 31 and the filter screen 32 both unfold to close the air inlet 1 again.

[0041] When it is necessary to disinfect the indoor area, after the ultraviolet disinfection lamp 9 extends out of the air inlet 1, if the louver curtains 31 and the filter screen 32 are both horizontally installed and the first fixing plate 61 is located directly above the air inlet 1, first the elevating assembly 82 is started to lower the ultraviolet disinfection lamp 9 to an appropriate height, and then the swinging assembly 72 is started to make the ultraviolet disinfection lamp 9 swing back and forth, so as to perform large - range dynamic disinfection of the indoor area and also complete the disinfection of the environment outside the air inlet 1, facilitating the daily indoor disinfection in the hospital; if the air inlet 1 is vertically opened, the louver curtains 31 and the filter screen 32 are both vertically installed, and the first fixing plate 61 is located directly behind the air inlet 1, at this time, the flipping assembly 62 needs to be started first to drive the second fixing plate 71 to rotate downward by ninety degrees. Then the elevating assembly 82 is started to lower the ultraviolet disinfection lamp 9 to an appropriate height, and then the swinging assembly 72 is used to drive the ultraviolet disinfection lamp 9 to swing back and forth to disinfect the indoor area.

[0042] Reference Figure 2 and Figure 3 At one end of the installation sleeve 21 with an opening, a positioning square frame 22 is fixedly connected. After the installation sleeve 21 is inserted into the air inlet 1, it is bolted to the wall through the positioning square frame 22, thereby fixing the installation sleeve 21 in the air inlet 1. The shape of the installation sleeve 21 is adapted to the shape of the air inlet 1. On one side in the length direction inside the installation sleeve 21, a rotating shaft 33 is rotatably connected, and the axis of the rotating shaft 33 is parallel to the axis of the installation sleeve 21. One end of each of the louver curtain 31 and the filter screen 32 is tied to the rotating shaft 33 by a rope for convenient disassembly and cleaning, and the other ends of the two are fixedly connected through a connecting plate 34. The filter screen 32 is located on the side of the louver curtain 31 facing the air conditioner unit. The indoor return air first passes through the louver curtain 31, then is filtered by the filter screen 32, and then enters the air conditioner unit after being disinfected by the ultraviolet disinfection lamp 9. In order to prevent the ultraviolet disinfection lamp 9 from irradiating the human body, both the louver curtain 31 and the filter screen 32 are made of light-shielding materials to play a protective role.

[0043] Reference Figure 2 and Figure 3 Two sets of winding components 4 are provided, and the two sets are respectively located at both ends of the rotating shaft 33 for driving the rotating shaft 33 to rotate. The winding component 4 includes two belt pulleys 42 and a gear 43. A rotating rod 41 is rotatably connected to the inner wall of the installation sleeve 21. The rotating rod 41 is located on the side of the filter screen 32 away from the louver curtain 31 and on the side of the installation sleeve 21 away from the rotating shaft 33. The axis of the rotating rod 41 is parallel to the axis of the rotating shaft 33. The two belt pulleys 42 are respectively coaxially fixedly connected to the rotating shaft 33 and the rotating rod 41. The two belt pulleys 42 are connected by a belt. A relief groove 23 is provided on the inner walls at both ends of the installation sleeve 21. One set of the two belt pulleys 42 and the belt are located in the corresponding relief groove 23. The gear 43 is coaxially fixedly connected to the rotating rod 41. Two racks 44 are fixedly connected to the first fixing plate 61. The length direction of the racks 44 is parallel to the telescopic direction of the cylinder 51. The two racks 44 are respectively engaged with the two gears 43. When the cylinder 51 drives the first fixing plate 61 to slide until the racks 44 are located below the gears 43, the racks 44 are engaged with the gears 43 to drive the gears 43 to rotate. The gears 43 drive the belt pulleys 42 thereon to rotate through the rotating rod 41. The belt pulleys 42 drive the other belt pulley 42 to rotate through the belt, and the other belt pulley 42 drives the rotating shaft 33 to rotate, thereby winding or stretching the louver curtain 31 and the filter screen 32.

[0044] Reference Figure 2 and Figure 3, on one side of the installation sleeve 21 close to the connecting plate 34, two springs 45 are fixedly connected. The other ends of the two springs 45 are respectively fixedly connected to both ends of the connecting plate 34. When the louver curtain 31 and the filter screen 32 are extended, due to the pulling force of the springs 45, the louver curtain 31 and the filter screen 32 can be unfolded. A sealing plate 46 is also fixedly connected to the opening of the installation sleeve 21 facing the interior. The sealing plate 46 is located on the side of the spring 45 close to the interior. When the spring 45 retracts behind the sealing plate 46, the connecting plate 34 abuts against the sealing plate 46, thereby sealing the gap between the connecting plate 34 and the installation sleeve 21.

[0045] Refer to Figure 2 and Figure 3 , a mounting seat 52 is connected by bolts in the ceiling. The mounting seat 52 is located behind the air inlet 1. The cylinder 51 is installed on the mounting seat 52. The telescopic direction of the cylinder 51 is perpendicular to the plane where the air inlet 1 is located. The first fixing plate 61, the second fixing plate 71, and the third fixing plate 81 are all set in a U shape and each includes two side plates and a bottom plate. The bottom plate of the first fixing plate 61 on the side facing the cylinder 51 is fixedly connected to the telescopic shaft of the cylinder 51 by bolts. The length direction of the first fixing plate 61 is parallel to the length direction of the installation sleeve 21. The first fixing plate 61 is located between the two springs 45. After the louver curtain 31 and the filter screen 32 are wound up, the cylinder 51 can drive the first fixing plate 61 to slide between the connecting plate 34 and the sealing plate 46. Two racks 44 are respectively fixedly connected to the sides of the two side plates facing away from each other, and the racks 44 are located at the ends of the side plates far from the bottom plate. The racks 44 are within the width range of the side plates in their width direction. Since there is a gap between the gear 43 and the louver curtain 31, when the cylinder 51 drives the first fixing plate 61 to move to the position where the end of the rack 44 far from the bottom plate meshes with the gear 43, at this time, the louver curtain 31 and the filter screen 32 start to be wound up, thereby opening the air inlet 1. When the first fixing plate 61 moves to the air inlet 1, at this time, the louver curtain 31 and the filter screen 32 are just wound up to the space between the connecting plate 34 and the sealing plate 46 so that the first fixing plate 61 can pass through. At this time, the gear 43 also disengages from the rack 44. The opened space of the air inlet 1 is fixed. The first fixing plate 61 gradually extends but does not completely disengage from the air inlet 1 as the telescopic shaft of the cylinder 51 extends.

[0046] Refer to Figure 4The flip assembly 62 includes a flip motor 621, a flip main shaft 622, a flip secondary shaft 623 and two sets of flip pulleys 624. The flip motor 621 is fixedly connected to one side of a side plate facing the other side plate. The rotating shaft 33 of the flip motor 621 is coaxially fixedly connected to the flip main shaft 622. The other end of the flip main shaft 622 is rotatably connected to the other side plate. The axial direction of the flip main shaft 622 is parallel to the length direction of the first fixed plate 61. The flip secondary shaft 623 is rotatably connected between the two side plates, and the axial direction of the flip secondary shaft 623 is parallel to the axial direction of the flip main shaft 622. The flip secondary shaft 623 is located on the side of the flip main shaft 622 away from the bottom plate. The two sets of flip pulleys 624 are arranged between the flip main shaft 622 and the flip secondary shaft 623 and are respectively located at both ends of the flip main shaft 622. A set of flip pulleys 624 includes two flip pulleys 624, which are coaxially fixedly connected to the flip main shaft 622 and the flip secondary shaft 623, respectively, and the two flip pulleys 624 are connected by a belt. A connecting seat 625 is fixedly connected to the flip secondary shaft 623, and the connecting seat 625 is located between the two sets of flip pulleys 624. The bottom plate of the second fixed plate 71 is fixedly connected to the connecting seat 625, and the length direction of the second fixed plate 71 is parallel to the length direction of the first fixed plate 61.

[0047] When the air inlet 1 is opened vertically, the first fixed plate 61 is installed horizontally in the ceiling. When the cylinder 51 extends the first fixed plate 61 out of the air inlet 1, the first fixed plate 61 moves to the point where the second fixed plate 71 is fully extended out of the air inlet 1 and stops. At this time, the flip motor 621 starts, driving the flip main shaft 622 to rotate. The flip main shaft 622 drives the flip secondary shaft 623 to rotate downward ninety degrees through the flip pulley 624, thereby driving the second fixed plate 71 to rotate downward ninety degrees.

[0048] Reference Figure 4The swing assembly 72 includes a swing motor 721, a swing main shaft 722 and a swing secondary shaft 723. The swing motor 721 is fixedly connected to one end of the second fixed plate 71. The rotation axis of the swing motor 721 is coaxially fixedly connected to the swing main shaft 722. The axial direction of the swing main shaft 722 is parallel to the length direction of the second fixed plate 71. A fixed block 724 is fixedly connected to the side of the bottom plate of the second fixed plate 71 away from the connecting seat 625. The swing main shaft 722 is rotatably connected between the swing motor 721 and the fixed block 724. The two side plates of the second fixed plate 71 are both rotatably connected to the opposite sides with swing rods 725. The swing secondary shaft 723 is fixedly connected between the two swing rods 725 and is located at one end of the swing rod 725 close to the swing motor. The axial direction of the swing secondary shaft 723 is parallel to the axial direction of the swing main shaft 722. The bottom plate of the second fixed plate 71 is rotatably connected to the side of the connecting seat 625, and the first connecting rod 726 is axially perpendicular to the axial direction of the swing main shaft 722, and one end of the swing main shaft 722 extends out of the fixed block 724, and the first connecting rod 726 and the swing main shaft 722 are coaxially fixedly connected with a bevel gear 727, and the two bevel gears 727 are meshed, and the other end of the first connecting rod 726 is fixedly connected to the second connecting rod 728, and the length direction of the second connecting rod 728 is perpendicular to the length direction of the first connecting rod 726, and the other end of the second connecting rod 728 is rotatably connected to the third connecting rod 729, and the third connecting rod 729 is axially parallel to the first connecting rod 726, and the third connecting rod 729 is fixedly connected to the end away from the bevel gear 727 with a fixing ring 730, and the fixing ring 730 is coaxially sleeved on the swing secondary shaft 723.

[0049] After the swing motor 721 is started, it drives the swing main shaft 722 to rotate. The swing main shaft 722 drives the first connecting rod 726 to rotate through the bevel gear 727 group. The first connecting rod 726 drives the second connecting rod 728 to rotate around the first connecting rod 726. Since the swing sub-shaft 723 is fixed between the two swing rods 725, when the second connecting rod 728 rotates, it drives the swing sub-shaft 723 to swing back and forth around the rotation center of the two swing rods 725 through the third connecting rod 729. At this time, the third connecting rod 729 slides up and down in the second connecting rod 728, driving the fixed ring 730 to slide back and forth on the swing sub-shaft 723 along its axial direction.

[0050] Reference Figure 5, The third fixing plate 81 is fixedly connected between two swing rods 725 and is located at one end of the swing rods 725 away from the swing sub-shaft 723. The length direction of the third fixing plate 81 is parallel to the length direction of the second fixing plate 71. The lifting assembly 82 includes a lifting motor 821 fixedly connected inside the third fixing plate 81. A lifting shaft 822 is coaxially fixedly connected to the rotating shaft of the lifting motor 821. The axial direction of the lifting shaft 822 is parallel to the length direction of the third fixing plate 81, and the other end of the lifting shaft 822 is rotatably connected to the side plate of the third fixing plate 81. Two winding rings 823 are coaxially fixedly connected to the lifting shaft 822. The two winding rings 823 are respectively located at both ends of the lifting shaft 822. Suspension ropes 824 are wound on both winding rings 823. Hooks 825 are fixedly connected to the bottom ends of the two suspension ropes 824. Mounting rings 826 are clamped at both ends of the ultraviolet disinfection lamp 9. The two hooks 825 are respectively hung inside the two mounting rings 826.

[0051] When it is necessary to wipe the surface of the ultraviolet disinfection lamp 9, start the lifting motor 821. The lifting motor 821 drives the lifting shaft 822 to rotate. The lifting shaft 822 drives the winding ring 823 to rotate, thereby lowering the suspension rope 824 and lowering the ultraviolet disinfection lamp 9 to a height convenient for wiping, so as to facilitate wiping and cleaning it.

[0052] The implementation principle of the air inlet structure of the hospital air conditioning system with a disinfection function in the embodiment of the present application is as follows: Bolt the cylinder 51 to the ceiling through the mounting seat 52, and then bolt-connect the cylinder 51 and the first fixing plate 61, install the first fixing plate 61 in the ceiling, and then place the mounting sleeve 21 at the air inlet 1 and fix it with bolts.

[0053] When the air conditioner is working, the ultraviolet disinfection lamp 9 is also in the on state to disinfect the filter net 32. When it is necessary to regularly wipe and clean the ultraviolet disinfection lamp 9, first start the cylinder 51, so that the telescopic shaft of the cylinder 51 extends to drive the first fixing plate 61 to move in the direction close to the filter net 32. During the movement, the rack 44 on the first fixing plate 61 moves to the gear 43 and meshes with it. As the first fixing plate 61 continues to move, the gear 43 rotates. The gear 43 drives the pulley 42 on it to rotate through the rotating rod 41. The pulley 42 drives another pulley 42 to rotate through the belt. The other pulley 42 drives the rotating shaft 33 to rotate, thereby winding up the louver 31 and the filter net 32, so that a channel appears between the connecting plate 34 and the sealing plate 46 for the first fixing plate 61 to extend out of the air inlet 1.

[0054] When the first fixed plate 61 moves to the air inlet 1, at this time, the louver 31 and the filter net 32 are just wound into the space between the connecting plate 34 and the sealing plate 46 so that the first fixed plate 61 can pass through. At this time, the gear 43 also disengages from the rack 44, and the space opened by the air inlet 1 is fixed. The first fixed plate 61 gradually extends as the telescopic shaft of the cylinder 51 elongates but does not completely disengage from the air inlet 1.

[0055] Start the lifting motor 821. The lifting motor 821 drives the lifting shaft 822 to rotate, and the lifting shaft 822 drives the winding ring 823 to rotate, thereby lowering the suspension rope 824 and lowering the ultraviolet disinfection lamp 9 to a height convenient for wiping, so as to facilitate wiping and cleaning.

[0056] When it is necessary to disinfect the indoor space, after the first fixed plate 61 extends out of the air inlet 1, it is divided into two cases: First, the air inlet 1 is horizontally opened, the louver 31 and the filter net 32 are both horizontally installed, and the first fixed plate 61 is located directly above the air inlet 1. Start the lifting motor 821 to lower the ultraviolet disinfection lamp 9 to an appropriate height, and then start the swing motor 721. The swing motor 721 drives the swing main shaft 722 to rotate, and the swing main shaft 722 drives the first connecting rod 726 to rotate through the bevel gear 727 group. The first connecting rod 726 drives the second connecting rod 728 to rotate around the first connecting rod 726. The second connecting rod 728 drives the swing secondary shaft 723 to reciprocally swing around the rotation center of the two swing rods 725 through the third connecting rod 729, driving the third fixed plate 81 to reciprocally swing, thereby driving the ultraviolet disinfection lamp 9 to reciprocally swing back and forth through the suspension rope 824, so as to perform large-range dynamic disinfection of the room.

[0057] Second, the air inlet 1 is vertically opened, the louver 31 and the filter net 32 are both vertically installed, and the first fixed plate 61 is located directly behind the air inlet 1. At this time, it is necessary to first start the flipping motor 621. The flipping motor 621 drives the flipping main shaft 622 to rotate, and the flipping main shaft 622 drives the flipping secondary shaft 623 to rotate downward by 90 degrees through the flipping pulley 624, thereby driving the second fixed plate 71 to rotate downward by 90 degrees. At this time, start the lifting motor 821 again to lower the ultraviolet disinfection lamp 9 to an appropriate height, and then start the swing motor 721 to drive the ultraviolet disinfection lamp 9 to reciprocally swing back and forth through the suspension rope 824 for indoor disinfection.

[0058] After the ultraviolet disinfection lamp 9 is cleaned or the indoor disinfection is completed, first start the lifting motor 821 to lift the ultraviolet disinfection lamp 9 and reset it into the third fixing plate 81, and then turn off the swing motor 721 to reset the third fixing plate 81 into the second fixing plate 71. At this time, if the second fixing plate 71 is vertically arranged with the first fixing plate 61, it is necessary to start the flipping motor 621 to flip the second fixing plate 71 upward by ninety degrees and reset it into the first fixing plate 61. If the second fixing plate 71 is parallel to the first fixing plate 61, there is no need to start the flipping motor 621. After the reset is completed, start the cylinder 51. The telescopic rod of the cylinder 51 contracts to drive the first fixing plate 61 to retract into the ceiling. As the first fixing plate 61 moves, the rack 44 contacts the gear 43, and the rack 44 drives the gear 43 to rotate in the reverse direction, thereby lowering the louver curtain 31 and the filter screen 32. When the first fixing plate 61 completely enters the ceiling, due to the pulling force of the spring 45, the lowered louver curtain 31 and filter screen 32 are stretched out, thereby closing the air inlet 1 and completing the reset of the ultraviolet disinfection lamp 9 at the same time.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
