Description

Technical Field

[0001] The invention belongs to the technical field of air disinfectors, in particular to a high-efficiency air disinfector for cabins. Background Art

[0002] An air disinfector is a machine that disinfects the air through the principles of filtration, purification, and sterilization. The working principles of air disinfectors vary, and they mainly have the ability to kill microorganisms such as bacteria, viruses, molds, spores, and ensure the cleanliness of the air. Generally speaking, an air disinfector first uses coarse filtration to filter out larger particles of impurities in the air, and then disinfects and sterilizes the air through means such as ultraviolet light, and then filters small particles through a HEPA filter.

[0003] In order to maintain the high efficiency 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 inside the disinfection machine sucked into the fan will mainly enter from the middle of the filter plate, which will cause particulate matter to accumulate in the middle of the filter plate, causing the filter holes in the middle to be quickly blocked. Because the filter plate in the middle is blocked, 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 exposure time is insufficient, and it cannot play a role in disinfection. Therefore, a high-efficiency air disinfection machine for square cabins 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, which makes it impossible to achieve the disinfection effect, the present invention provides a high-efficiency air disinfector for a cabin.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts 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 shelter, comprising a main body shell 1, an air inlet grid plate 2 movably connected to one side of the main body shell 1, a driving mechanism 3 and a blocking mechanism 4 provided on the inner side of the air inlet grid plate 2, a coarse filter plate 5 slidably connected to the inner side of the air inlet grid plate 2, a metal air guide assembly 7 and an ultraviolet lamp 8 fixedly connected to the interior of the main body shell 1, and a HEPA filter plate 9 and an air outlet grid plate 10 fixedly connected to the side of the main body shell 1 away from the air inlet grid plate 2;

[0037] Among them, 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, and the end of the transmission gear rod 32 away from the gear ring 31 is meshed with a reduction motor 33. The gear ring 31 has extrusion blocks 34 distributed in a ring shape inside.

[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 shell 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. 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 outward through the traction rope 433 and the sliding rod 431 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 intake grille plate 2 after it is unfolded, so that the air enters from the grid on the periphery of the air intake grille 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 avoid the air passing mainly through the middle of the coarse filter plate 5 for a long time, resulting in the coarse filter plate 5 filtering impurities to block the middle part. The setting of the metal air guide component 7 and the ultraviolet lamp tube 8 can disinfect and sterilize the air. By setting the HEPA filter plate 9, small particulate impurities that the coarse filter plate 5 cannot filter out can be filtered.

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

[0040] Adopt the above scheme: 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 grille 2, the reduction motor 33 is fixedly connected to the lower end of the air intake grille 2, the end of the extrusion block 34 close to the blocking mechanism 4 is provided with an inclined surface, and the chute 35 is annularly distributed and provided inside the air intake grille 2. The chute 35 is arc-shaped and gradually tilted toward the gear ring 31;

[0042] The blocking mechanism 4 includes a telescopic windshield cloth 41, and the outer side of the telescopic windshield cloth 41 is provided with a ring-shaped expansion component 42, the four outer corners of the telescopic windshield cloth 41 are fixedly connected to the pulling component 43, the inner side of the telescopic windshield cloth 41 is abutted with an elastic push plate 44, 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 solution is adopted: by setting the driving mechanism 3, it is easy to pull the blocking mechanism 4 to unfold, and the gear ring 31 and the transmission gear rod 32 are rotatably connected to the air intake grille plate 2, which can maintain stability during operation. The reduction motor 33 is provided for driving the gear ring 31 to rotate through the transmission gear rod 32, and the extrusion blocks 34 distributed in an annular shape inside the gear ring 31 are used to push the extrusion limit block 434 to move. The chute 35 is provided for releasing the interference between the extrusion block 34 and the limit block 434, and the chute 35 is set to gradually tilt toward the gear ring 31, so that the extrusion block 34 slides inside the chute 35, will be gradually pushed, and finally slide out from the inside of the chute 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 set 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 Figure 9 As shown, the expansion assembly 42 includes a pair of rotating connecting rods 421, a expansion support rod 422 is slidably connected between the pair of rotating connecting rods 421, and fixing pins 423 are linearly distributed on one side of the expansion support rod 422 close to the telescopic windshield cloth 41;

[0046] The pulling assembly 43 includes a slide rod 431 with a spring 432 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 solution is adopted: by providing an expansion assembly 42 for pulling the telescopic windshield 41 to expand and support the telescopic windshield 41, by providing a rotating connecting rod 421 and an expansion support rod 422, so that the rotating connecting rod 421 can slide from the middle of the expansion support rod 422 to both sides, so as to keep the expansion support rod 422 moving stably, and the telescopic windshield 41 is pulled to expand. By providing a fixing nail 423 on the expansion support rod 422, the expansion support rod 422 can stably pull the telescopic windshield 41 to move and expand;

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

[0049] like Figure 7 、 Figure 8 and Figure 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 and located at the four sides of the outside of the telescopic windshield cloth 41, and the fixing nail 423 passes through 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, and 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 limit block 434 is close to the end of the gear ring 31. A groove matching the extrusion block 34 is opened, and the limit block 434 is in conflict with the extrusion block 34.

[0050] The above-mentioned scheme is adopted: by setting the stretching support rod 422 at the four sides of the outside 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 to the four sides and opened. At the same time, a pair of rotating connecting rods 421 slide to both sides inside the stretching support rod 422. The setting of the sliding rod 431 can pull the telescopic windshield cloth 41 and the rotating connecting rod 421 to move. By setting the traction rope 433 and the limit block 434, the traction rope 433 can be pulled by the limit block 434 to move, and then the slide rod 431 is pulled to move. At the same time, the groove on the limit block 434 that matches the extrusion block 34 enables the extrusion block 34 to 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 conflict 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 interior of the slide grooves 35, so that the extrusion blocks 34 and the limit blocks 434 are no longer in conflict.

[0052] The above solution is adopted: the extrusion block 34 and the slide groove 35 are set to the same 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 expansion component 42 to move, so that the telescopic windshield cloth 41 can be smoothly expanded to the surroundings to block the air and pass 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 limiting block 434 is pushed by the extrusion block 34 to move, so that the limiting block 434 is pulled by the traction rope 433 to move the slide bar 431. When the extrusion block 34 moves to the chute 35, the extrusion block 34 is squeezed by the limiting block 434, so that the extrusion block 34 is squeezed into the interior of the chute 35 by the limiting block 434, so that the extrusion block 34 and the limiting block 434 are released from conflict. Then, under the thrust of the spring 432, the limiting block 434 is pulled by the slide bar 431 through the traction rope 433 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 to the four sides, 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 released from the 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-mentioned 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 the four sides. When the limit block 434 is released from the conflict with the extrusion block 34, the fixing nail 423 pushes the sliding rod 431 to reset, and the traction rope 433 and the limit block 434 are pulled by the sliding rod 431 to reset. 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 Figure 11 and Figure 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 provided on the outer side of the second guide plate 72. A middle guide plate 74 and a second return plate 75 are fixedly connected to the sides of the first guide plate 71 and the second guide plate 72 away from the fan 6 respectively.

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

[0057] The above solution is adopted: the design of the metal air guide assembly 7 can guide the air blown out by the fan 6 by the metal air guide assembly 7, so that the air passes through the irradiation of the ultraviolet lamp 8. By providing 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. Then, the air is guided by the first return plate 73 and the middle guide plate 74 to the second return plate 75 and the middle guide plate 74 respectively, and then blown to the HEPA filter plate 9. 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 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 under the irradiation of the ultraviolet lamp 8 for a longer time during the guiding process. At the same time, the obstruction 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 8, which would shorten the service life of the fan 6 and the HEPA filter plate 9 due to the photodegradation and aging effects of ultraviolet rays.

[0058] The working principle and usage 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 grille 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 grille 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 hits 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 air is then drawn out of the air filter 5 and out of the air filter 5. The air is then drawn out of the air filter 5 and out of the air filter 5. The air is then drawn out of the air filter 5 and out of the air filter 5.

[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 respectively guide the air to the inside of the first return plate 73 and the middle guide plate 74, so that the air undergoes a buffering deflection inside the first return plate 73 and the middle guide plate 74, allowing the air to stay inside the first return plate 73 and the middle guide plate 74 for a longer time, so that the air can be sufficiently irradiated by the ultraviolet lamp 8 to complete the disinfection and sterilization of the air. Then, the air is guided by the first return plate 73 and the middle guide plate 74 respectively and blown to the second return plate 75 and the middle guide plate 74, and then blown to 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.
