Description

Technical Field

[0001] The invention belongs to the technical field of air disinfection machines, in particular to a high-efficiency air disinfection machine for a square cabin. Background Art

[0002] An air disinfector is a machine that disinfects the air through filtering, purifying, and sterilizing. The working principles of air disinfectors vary, and they can mainly kill microorganisms such as bacteria, viruses, molds, spores, and ensure the cleanliness of the air. In the square cabins, there are generally patients with certain infectiousness, so air disinfection is a necessary means. Generally speaking, the air disinfector first uses coarse filtration to filter out larger particles of impurities in the air, and then disinfects and sterilizes the air through ultraviolet lamps and other means, and then filters small particles through a HEPA filter.

[0003] In order to maintain the high-efficiency operation of the disinfection machine, a higher-power fan is generally used to increase the speed of air flow. A large fan corresponds to a larger air inlet and a larger filter plate, and the fan is not too large. Therefore, the air sucked into the disinfection machine by the fan will mainly enter from the middle of the filter plate, which will cause particulate debris to accumulate in the middle of the filter plate, causing the filter holes in the middle to be quickly blocked. Because the middle is blocked by the blocked filter plate, the fan can only inhale air from the outside of the filter plate, resulting in a decrease in the air intake, affecting the efficiency of the disinfection machine. In addition, the traditional ultraviolet lamp disinfection machine simply fixes the ultraviolet lamp between the fan and the filter plate. Due to the aging and photodegradation of the ultraviolet lamp, the service life of the plastic components and filter plates inside the disinfection machine will be greatly reduced. At the same time, the air blows directly through the ultraviolet lamp, and the irradiation time is insufficient, and the disinfection effect cannot be achieved. Therefore, a high-efficiency air disinfection machine for a cabin is proposed. Summary of the invention

[0004] In order to solve the problems raised in the above background technology that the middle part of the filter plate is easily clogged and the irradiation time of the ultraviolet lamp is insufficient to achieve the disinfection effect, the present invention provides a high-efficiency air disinfector for a cabin.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-efficiency air disinfector for a shelter, comprising a main body shell, one side of the main body shell is movably connected to an air inlet grid plate, the inner side of the air inlet grid plate is provided with a driving mechanism and a blocking mechanism, the inner side of the air inlet grid plate is slidably connected to a coarse filter plate, the inside of the main body shell is fixedly connected to a metal air guide assembly and an ultraviolet lamp tube, and the side of the main body shell away from the air inlet grid plate is fixedly connected to a HEPA filter plate and an air outlet grid plate;

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention solves the problem that air is easily blocked when passing through the middle of the coarse filter plate by arranging the cooperation of structures such as the driving mechanism and the blocking mechanism.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 12 As shown, the present invention provides a high-efficiency air disinfector for a cabin, comprising a main body shell 1, an air inlet grid plate 2 is movably connected to one side of the main body shell 1, a driving mechanism 3 and a blocking mechanism 4 are arranged inside the air inlet grid plate 2, a coarse filter plate 5 is slidably connected to the inside of the air inlet grid plate 2, a metal air guide component 7 and an ultraviolet lamp tube 8 are fixedly connected inside the main body shell 1, and a HEPA filter plate 9 and an air outlet grid plate 10 are fixedly connected to the side of the main body shell 1 away from the air inlet grid plate 2;

[0037] The driving mechanism 3 includes a gear ring 31 and a slide groove 35. The bottom of the gear ring 31 is meshed with a transmission gear rod 32. The end of the transmission gear rod 32 away from the gear ring 31 is meshed with a reduction motor 33. Extrusion blocks 34 are distributed in a ring shape inside the gear ring 31.

[0038] The above scheme is adopted: air is sucked from the air inlet grid plate 2 by the fan 6, so that the air passes through the coarse filter plate 5 and enters the interior of the main housing 1, and the gear ring 31 is driven to rotate by the reduction motor 33 through the transmission gear rod 32, so that the gear ring 31 drives the extrusion block 34 to rotate synchronously, so that the extrusion block 34 conflicts with the limit block 434, and at this time, the extrusion block 34 squeezes and pushes the limit block 434 to move synchronously, and the limit block 434 pulls the rotating connecting rod 421 and the telescopic windshield cloth 41 to move outward through the traction rope 433 and the sliding rod 431, so as to pull the four corners of the telescopic windshield cloth 41 to unfold, and at the same time, the rotating connecting rod 421 drives the support rod 422 to move , and then pull the four sides of the retractable windshield cloth 41 to open all around, so that the retractable windshield cloth 41 will block the grid in the middle of the air inlet grid plate 2 after it is unfolded, so that the air enters from the grid on the periphery of the air inlet grid plate 2, and then passes through the periphery of the coarse filter plate 5, so that the air is temporarily blocked, and the outer filter holes of the coarse filter plate 5 are used for filtering to prevent the air from passing mainly through the middle of the coarse filter plate 5 for a long time, resulting in the coarse filter plate 5 blocking the middle part of the air filtered by impurities. The arrangement of the metal air guide component 7 and the ultraviolet lamp tube 8 can disinfect and sterilize the air. By arranging the HEPA filter plate 9, small particle impurities that cannot be filtered by the coarse filter plate 5 can be filtered.

[0039] like Figure 2 , Figure 3 and Fig.11 As shown, a fan 6 is installed in the middle of the main shell 1, the air inlet grid plate 2 is slidably connected to the main shell 1, a slideway is opened inside the air inlet grid plate 2, and the driving mechanism 3 is rotatably connected inside the slideway.

[0040] The above solution is adopted: by setting the air intake grid plate 2, the air intake grid plate 2 supports the driving mechanism 3, the blocking mechanism 4 and the coarse filter plate 5, such as Figure 2 As shown, limiting grooves are provided on both sides of the interior of the air inlet grid plate 2, and the coarse filter plate 5 is slidably connected inside the limiting grooves, so that the coarse filter plate 5 can be easily installed.

[0041] like Figure 4 , Figure 5 and Figure 6 As shown, the gear ring 31 and the transmission gear rod 32 are both rotatably connected to the air intake grid plate 2, the reduction motor 33 is fixedly connected to the lower end of the air intake grid plate 2, the end of the extrusion block 34 close to the blocking mechanism 4 is provided with an inclined surface, and the slide groove 35 is annularly distributed and opened inside the air intake grid plate 2, and the slide groove 35 is arc-shaped and gradually tilted toward the gear ring 31;

[0042] The blocking mechanism 4 includes a telescopic windshield cloth 41, and an opening component 42 is distributed in a ring shape on the outside of the telescopic windshield cloth 41, and pulling components 43 are fixedly connected to the four corners of the outside of the telescopic windshield cloth 41. An elastic push plate 44 abuts against the inner side of the telescopic windshield cloth 41. The telescopic windshield cloth 41 is located in the middle of the air intake grille 2, and the telescopic windshield cloth 41 is fixedly connected to the air intake grille 2, and the elastic push plate 44 is fixedly connected to the middle of the air intake grille 2.

[0043] The above scheme is adopted: by setting the driving mechanism 3, it is convenient to pull the blocking mechanism 4 to unfold, and the gear ring 31 and the transmission gear rod 32 are rotatably connected with the air intake grid plate 2, which can maintain stability during operation. The reduction motor 33 is set to drive the gear ring 31 to rotate through the transmission gear rod 32, and the extrusion block 34 distributed in a ring shape inside the gear ring 31 is used to push the extrusion limit block 434 to move. The slide groove 35 is set to release the conflict between the extrusion block 34 and the limit block 434, and the slide groove 35 is set to gradually tilt toward the gear ring 31, so that the extrusion block 34 slides inside the slide groove 35, will be gradually pushed, and finally slide out from the slide groove 35;

[0044] By setting up a blocking mechanism 4, the air at the air inlet can be blocked so that the air can pass through the coarse filter plate 5 evenly. By setting up a retractable windshield cloth 41, the air can be blocked. The setting of the stretching component 42 and the pulling component 43 is used to stretch the retractable windshield cloth 41 to unfold it. The elastic push plate 44 arranged inside the retractable windshield cloth 41 is used to push the retractable windshield cloth 41 to fold and reset.

[0045] like Figure 7 , Figure 8 and Fig. 9 As shown, the expansion assembly 42 includes a pair of rotating connecting rods 421, and an expansion support rod 422 is slidably connected between the pair of rotating connecting rods 421. The expansion support rod 422 is linearly distributed with fixing nails 423 on one side close to the telescopic windshield cloth 41;

[0046] The pulling assembly 43 includes a slide rod 431 , a spring 432 is wrapped around the middle of the slide rod 431 , one end of the slide rod 431 away from the telescopic windshield cloth 41 is fixedly connected to a traction rope 433 , and one end of the traction rope 433 is fixedly connected to a limiting block 434 .

[0047] The above scheme is adopted: by setting an expansion component 42 for pulling the telescopic windshield cloth 41 to expand and support the telescopic windshield cloth 41, by setting a rotating connecting rod 421 and an expansion support rod 422, the rotating connecting rod 421 can slide from the middle of the expansion support rod 422 to both sides to keep the expansion support rod 422 moving stably, and the telescopic windshield cloth 41 is pulled to expand, and by setting a fixing nail 423 on the expansion support rod 422, the expansion support rod 422 can stably pull the telescopic windshield cloth 41 to move and expand;

[0048] The pulling assembly 43 is set up to pull the telescopic windshield cloth 41 to unfold, and simultaneously pull the opening assembly 42 to extend and unfold. The spring 432 wrapped around the middle of the slide bar 431 can push the slide bar 431 to reset after the slide bar 431 moves. The traction rope 433 and the limit block 434 are used to pull the slide bar 431 to move, and then the slide bar 431 pulls the opening assembly 42 and the telescopic windshield cloth 41 to move.

[0049] like Figure 7 , Figure 8 and Fig. 9 As shown, the rotating connecting rod 421 is rotatably connected to the top of the sliding rod 431, and the support rod 422 is stretched out to be located at the four sides of the outside of the telescopic windshield cloth 41, the fixing nail 423 penetrates the telescopic windshield cloth 41, and the fixing nail 423 is fixedly connected to the telescopic windshield cloth 41; the sliding rod 431 is slidably connected to the air intake grille plate 2, one end of the spring 432 is fixedly connected to the air intake grille plate 2, the traction rope 433 is movably connected inside the air intake grille plate 2, the limit block 434 is in conflict with the gear ring 31, and the end of the limit block 434 close to the gear ring 31 is provided with a groove matching the extrusion block 34, and the limit block 434 is in conflict with the extrusion block 34.

[0050] The above scheme is adopted: by setting the stretching support rod 422 at the four sides of the outer side of the telescopic windshield cloth 41, when the rotating connecting rod 421 is pulled by the sliding rod 431, the stretching support rod 422 is pulled to move and open in all directions by a pair of rotating connecting rods 421, and at the same time, a pair of rotating connecting rods 421 slide to both sides inside the stretching support rod 422 respectively. The setting of the sliding rod 431 can pull the telescopic windshield cloth 41 and the rotating connecting rod 421 to move by the sliding rod 431, and by setting a traction rope 433 and a limit block 434, the traction rope 433 can be pulled by the limit block 434 to move, and then the slide rod 431 can be pulled to move, and at the same time, a groove matching the extrusion block 34 is opened on the limit block 434, so that the extrusion block 34 can push the limit block 434 to move.

[0051] like Figures 4 to 9 As shown, the number of extrusion blocks 34, slide grooves 35 and limit blocks 434 is the same, and the extrusion blocks 34 are slidably connected inside the slide grooves 35. When the gear ring 31 rotates to drive the extrusion blocks 34 to move, the extrusion blocks 34 collide with the limit blocks 434 and push the limit blocks 434 to move. When the extrusion blocks 34 move to the slide grooves 35, the extrusion blocks 34 are squeezed by the limit blocks 434 into the slide grooves 35, so that the extrusion blocks 34 and the limit blocks 434 are no longer in conflict.

[0052] The above scheme is adopted: the extrusion block 34 and the slide groove 35 are set to be the same in number as the limit block 434, so that the limit block 434 can be pushed and squeezed by the extrusion block 34 to move synchronously, and then the slide rod 431 can simultaneously pull the telescopic windshield cloth 41 and the opening component 42 to move, so that the telescopic windshield cloth 41 can be smoothly expanded to the surroundings to block the air, so that the air passes through the outer ring of the coarse filter plate 5. When the gear ring 31 rotates to drive the extrusion block 34 to move, the extrusion block 34 is driven by the gear ring 31 to move to the limit block 434. The extrusion block 34 pushes the limit block 434 to move, so that the limit block 434 moves by pulling the slide bar 431 through the traction rope 433. When the extrusion block 34 moves to the slide groove 35, the extrusion block 34 is squeezed by the limit block 434, so that the extrusion block 34 is squeezed into the interior of the slide groove 35 by the limit block 434, so that the extrusion block 34 and the limit block 434 are no longer in conflict, and then the limit block 434 is pulled by the slide bar 431 through the traction rope 433 under the thrust of the spring 432 to move and reset.

[0053] like Figures 4 to 9 As shown, the limit block 434 pulls the slide bar 431 to move through the traction rope 433, so that the slide bar 431 drives the telescopic windshield cloth 41 and the rotating connecting rod 421 to move, so that the telescopic windshield cloth 41 is pulled to open around, and at the same time, a pair of rotating connecting rods 421 pulls the support rod 422 to move outward. When the limit block 434 is no longer in conflict with the extrusion block 34, the fixing nail 423 pushes the slide bar 431 to move, and the slide bar 431 pulls the traction rope 433 and the limit block 434 to reset, and the elastic push plate 44 pushes the telescopic windshield cloth 41 to shrink and reset.

[0054] The above scheme is adopted: the limit block 434 pulls the sliding rod 431 to move through the traction rope 433, so that the sliding rod 431 moves to the four sides respectively, and at the same time, the sliding rod 431 drives the telescopic windshield cloth 41 and the rotating connecting rod 421 to move. When the sliding rod 431 pulls the telescopic windshield cloth 41 to unfold, the rotating connecting rod 421 is pulled synchronously, and the rotating connecting rod 421 drives the support rod 422 to move, so that the support rod 422 pulls the telescopic windshield cloth 41 to unfold, so that the telescopic windshield cloth 41 is pulled to open to the four sides, and when the limit block 434 is no longer in conflict with the extrusion block 34, the fixing nail 423 pushes the sliding rod 431 to reset, and the sliding rod 431 pulls the traction rope 433 and the limit block 434 to reset, and at the same time, the telescopic windshield cloth 41 is contacted and pulled, so that the elastic push plate 44 opens and pushes the telescopic windshield cloth 41 to shrink and reset.

[0055] like Fig.11 and Fig.12As shown, the metal air guide assembly 7 includes a first guide plate 71 and a second guide plate 72, a first return plate 73 is arranged outside the second guide plate 72, and a middle guide plate 74 and a second return plate 75 are fixedly connected to the first guide plate 71 and the second guide plate 72 on the side away from the fan 6 respectively;

[0056] The ultraviolet lamp 8 is located at the inner side of the first return plate 73 and the second return plate 75 respectively. The first guide plate 71 and the second guide plate 72 face the inside of the first return plate 73 and the second return plate 75 respectively. The middle guide plate 74 is located in the middle of the second return plate 75.

[0057] The above scheme is adopted: the design of the metal air guide component 7 can guide the air blown out by the fan 6 by the metal air guide component 7, so that the air is irradiated by the ultraviolet lamp tube 8. By setting the first guide plate 71 and the second guide plate 72, the first guide plate 71 and the second guide plate 72 can guide the air to the inside of the first return plate 73 and the middle guide plate 74, and then the air is guided by the first return plate 73 and the middle guide plate 74 to blow to the second return plate 75 and the middle guide plate 74 respectively, and then blown to the HEPA filter plate 9, and the HEPA filter plate 9 filters the tiny particles in the air and discharges them from the air outlet grid plate 10. The ultraviolet lamp tube 8 is respectively arranged on the inner side of the first return plate 73 and the second return plate 75, so that the air can stay longer under the irradiation of the ultraviolet lamp tube 8 during the guiding process. At the same time, the blocking of the first return plate 73 and the middle guide plate 74 can prevent the fan 6 and the HEPA filter plate 9 from being irradiated by the ultraviolet lamp tube 8, and the photodegradation and aging of the ultraviolet rays will shorten the service life of the fan 6 and the HEPA filter plate 9.

[0058] The working principle and use process of the present invention are as follows: when working, the fan 6 and the reduction motor 33 are started, and the fan 6 draws air from the air intake grid plate 2, so that the air passes through the coarse filter plate 5 and enters the interior of the main body shell 1. When the air enters the coarse filter plate 5 from the air intake grid plate 2, the reduction motor 33 drives the gear ring 31 to rotate through the transmission gear rod 32. When the gear ring 31 rotates, it will drive the extrusion block 34 to rotate synchronously, so that the extrusion block 34 moves. When the extrusion block 34 moves to the limit block 434 and contacts it, the extrusion block 34 will squeeze and push the limit block 434 to move synchronously, so that the limit block 434 pulls the sliding rod 431 to move outward through the traction rope 433, and then the sliding rod 431 will pull the rotating connecting rod 421 and the telescopic windshield cloth 41 to move outward, so as to pull the four corners of the telescopic windshield cloth 41 to unfold, and at the same time, the rotating connecting rod 421 slides outward inside the support rod 422 to keep the support rod 422 at an unchanged angle. The four sides of the telescopic windshield cloth 41 are pulled to open in all directions, so that the telescopic windshield cloth 41 blocks the grid in the middle of the air inlet grille plate 2, allowing air to enter from the grid on the periphery of the air inlet grille plate 2, and then pass through the periphery of the coarse filter plate 5 for filtering, and then be blown into the interior of the metal air guide component 7 through the fan 6; when the extrusion block 34 rotates to the slide slot 35, the extrusion block 34 will be squeezed into the interior of the slide slot 35 by the limit block 434, so that the extrusion block 34 and the limit block 434 are no longer in conflict, and then the limit block 434 is pulled by the slide rod 431 through the traction rope 433 under the thrust of the spring 432 to move and reset the limit block 434, so that the telescopic windshield cloth 41 shrinks and resets, and the air is blocked, so that the air mainly passes through the middle of the coarse filter plate 5, thereby repeatedly changing the area where the air passes through the coarse filter plate 5, so that the air passes through the coarse filter plate 5 evenly and separately, and avoids the situation where the middle filter sieve hole is blocked and dust particles are not filtered around;

[0059] When the air passes through the fan 6 and blows toward the metal air guide assembly 7, the first guide plate 71 and the second guide plate 72 guide the air to the inside of the first return plate 73 and the middle guide plate 74 respectively, so that the air is buffered and diverted inside the first return plate 73 and the middle guide plate 74, so that the air stays inside the first return plate 73 and the middle guide plate 74 for a longer time, so that the air can be adequately irradiated by the ultraviolet lamp 8 to complete the disinfection and sterilization of the air, and then the air is guided by the first return plate 73 and the middle guide plate 74 to blow toward the second return plate 75 and the middle guide plate 74 respectively, and then blown toward the HEPA filter plate 9, which filters the tiny particles in the air and discharges them from the air outlet grid plate 10 to complete the disinfection of the air.
