[0002] Currently, the decline in indoor air quality caused by urban pollution, building decoration pollution, germ transmission, or other reasons is a real problem faced by many cities in my country. Indoor air contains viruses, bacteria, spores, actinomycetes, fungi, formaldehyde, particulate matter, and airborne bacteria, etc. Therefore, air disinfection devices suitable for multiple environments are needed for disinfection, especially in public places such as hospitals where there are many types of germs, including many heat-sensitive germs.

[0003] There are many indoor air disinfection devices available now, and the commonly used disinfection methods include spray disinfection and air purifier disinfection.

[0016] Compared with the prior art, the present invention provides an indoor air disinfection device for multiple environments, which has the following beneficial effects:

[0017] 1. This multi-environment indoor air disinfection device reduces the air pressure in the first chamber. At this time, the air outside the disinfection box enters the filter chamber through the air inlet slot. After being filtered by the filter plate, the air enters the first chamber, and the steam generated by the steam component enters the filter chamber under the suction of the air inlet slot. The water vapor generated by the steam component kills visible viruses, bacteria, spores, actinomycetes and fungi in the air, thereby effectively disinfecting some bacteria and viruses in the air.

[0018] 2. This multi-environment indoor air disinfection device uses steam to enter the filter chamber and flow towards the filter plate along with the indoor air. The filter plate gradually becomes moist, which effectively enhances the adsorption effect of the filter plate on dust, impurities, and particulate matter. At this time, a small number of bacteria and viruses in the air in the filter chamber are adsorbed onto the filter plate along with the dust. The ultraviolet lamp in the filter chamber then irradiates the filter plate for a long time to sterilize it, thereby effectively improving the disinfection efficiency of indoor air.

[0019] 3. This multi-environment indoor air disinfection device gradually increases the amount of water on the filter plate, causing it to carry dust downwards. Eventually, the dust and water fall into the water chamber, where water vapor effectively washes away the dust on the filter plate, preventing a large accumulation of dust from affecting air intake and thus improving the efficiency of indoor air sterilization and disinfection. The dust and impurities on the filter plate, carrying some airborne viruses, bacteria, and other microorganisms, fall onto the water in the water chamber. The ultraviolet lamps in the filtration chamber and the first chamber then disinfect the bacteria and microorganisms in the water chamber, effectively improving the disinfection efficiency of indoor air.

[0020] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention uses ultraviolet lamps in the filter chamber to disinfect bacteria attached to the filter plate, thereby effectively improving the disinfection efficiency of indoor air.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4An indoor air disinfection device for multiple environments includes: a disinfection box 1, and further includes: a filter plate 2 fixed inside the disinfection box 1; a filter chamber 206 disposed between the filter plate 2 and the disinfection box 1; an air inlet slot 101 located on the side of the disinfection box 1 near the filter chamber 206; a sealing plate 111 fixed inside the disinfection box 1; a first cavity 113 disposed between the sealing plate 111 and the filter plate 2, with ultraviolet lamps 110 fixedly connected to both the first cavity 113 and the filter chamber 206; a first fixing plate 112 fixed to the bottom of the disinfection box 1; and a heating box 5 fixed to the disinfection box 1 near the air inlet slot 106. 1. One side of the chamber; water chamber 4, disposed between heating chamber 5 and first fixed plate 112; second chamber 114, disposed between sealing plate 111 and first fixed plate 112; air extraction assembly, disposed in first chamber 113, used to transport gas in first chamber 113 to second chamber 114; steam assembly, disposed in heating chamber 5; adsorption assembly, disposed in second chamber 114, and second chamber 114 is matched with adsorption assembly; chamber cover 102, detachably connected to the top of disinfection chamber 1, and the chamber cover 102 is provided with multiple exhaust grilles 103 for exhaust.

[0032] The air extraction assembly includes a pump set 3 fixed on a sealing plate 111. An air extraction steel pipe 301 is fixedly connected to the input end of the pump set 3. An air extraction hood 302 matching the filter plate 2 is fixedly connected to the end of the air extraction steel pipe 301 away from the pump set 3. An exhaust steel pipe 303 is fixedly connected to the output end of the pump set 3. An inclined plate 401 is fixedly connected inside the water chamber 4. The end of the inclined plate 401 near the heating box 5 is fixedly connected to the disinfection box 1. The output end of the exhaust steel pipe 303 is located on the lower side of the inclined plate 401. One end of the inclined plate 401 is located inside the second cavity 114.

[0033] When disinfecting indoor air in a hospital, first add an appropriate amount of water to the water chamber 4 so that the water level is higher than the bottom surface of the filter plate 2 and the bottom surface of the sealing plate 111. Place the disinfection box 1 in the central area of ​​the room, turn on the pump group 3, steam component and ultraviolet lamp 110. The pump group 3 draws air through the air extraction steel pipe 301 and the air extraction hood 302 to reduce the air pressure in the first chamber 113. At this time, the air outside the disinfection box 1 enters the filter chamber 206 through the air inlet slot 101. After the dust and particulate matter in the air are filtered by the filter plate 2, it enters the first chamber 113. The steam generated by the steam component enters the filter chamber 206 under the suction of the air inlet slot 101. The water vapor generated by the steam component kills viruses, bacteria, spores, actinomycetes and fungi in the air, thereby effectively disinfecting some bacteria and viruses in the air.

[0034] After the steam enters the filter chamber 206, it flows towards the filter plate 2 along with the indoor air, and the filter plate 2 gradually becomes moist, thereby effectively improving the adsorption effect of the filter plate 2 on dust, impurities and particulate matter. At this time, a small number of bacteria and viruses in the air in the filter chamber 206 are adsorbed on the filter plate 2 along with the dust. The ultraviolet lamp 110 in the filter chamber 206 irradiates the filter plate 2 for a long time to sterilize it, thereby effectively improving the disinfection efficiency of indoor air.

[0035] As the steam on filter plate 2 increases, the water on filter plate 2 gradually increases, causing it to carry the dust downwards. Eventually, the dust and water fall into the water chamber 4. The water vapor effectively washes away the dust on filter plate 2, thus effectively preventing the accumulation of a large amount of dust on filter plate 2 from affecting its air intake effect, thereby effectively improving the efficiency of indoor air sterilization and disinfection.

[0036] Dust and impurities on filter plate 2, along with some airborne viruses, bacteria, and other microorganisms, fall onto the water in water chamber 4. The ultraviolet lamp 110 in filter chamber 206 and first chamber 113 then disinfects the bacteria and microorganisms in water chamber 4, thereby effectively improving the disinfection efficiency of indoor air.

[0037] After the pump unit 3 draws the gas from the first chamber 113, it is discharged to the lower side of the inclined plate 401 through the exhaust steel pipe 303. After sterilization, the gas enters the water chamber 4 and flows into the second chamber 114 in a bubble-like manner along the inclined plate 401. At this time, the heat of the gas in the first chamber 113 is transferred to the water in the water chamber 4. The gas in the second chamber 114 is adsorbed and filtered by the adsorption component to adsorb and filter small molecule pollutants, influenza virus pathogens and bacteria, thereby effectively improving the purification and disinfection effect of indoor air.

[0038] Example 2: Refer to Figure 2 , Figure 3 and Figure 4 A multi-environment indoor air disinfection device, basically the same as in Embodiment 1, further comprising a steam component including a support block 507 fixed inside a heating chamber 5, a hollow tube 501 sealed and rotatably connected inside the support block 507, a first bevel gear 504 fixedly connected to one end of the hollow tube 501 inside the water chamber 4, a plurality of water-absorbing grooves 502 circumferentially formed on the side of the hollow tube 501 near the first bevel gear 504, a water-absorbing sponge 503 fixedly connected inside the hollow tube 501, a plurality of water-spraying nozzles 505 circumferentially formed on the end of the hollow tube 501 away from the first bevel gear 504, a heating plate 506 fixedly connected to the end of the support block 507 near the water-spraying nozzles 505, and the heating plate 506 matching the water-spraying nozzles 505, the heating plate 506 being frustoconical in shape, a conduit 508 matching the air inlet groove 101 fixedly connected to the heating chamber 5, and a drive component for driving the hollow tube 501 to rotate inside the disinfection chamber 1.

[0039] The drive assembly includes an impeller box 304 fixed inside the water chamber 4. A rotating shaft 305 is rotatably connected to the impeller box 304. One end of the rotating shaft 305 rotates on the first fixed plate 112. The end of the rotating shaft 305 away from the first fixed plate 112 is fixedly connected to a half bevel gear 309 that meshes with the first bevel gear 504. An impeller assembly 306 is fixedly connected to one end of the rotating shaft 305 inside the impeller box 304. The output end of the exhaust steel pipe 303 is fixedly connected to the input end of the impeller box 304. A connecting pipe 307 is fixedly connected to the output end of the impeller box 304.

[0040] When the gas in the pump unit 3 is discharged into the impeller box 304 through the exhaust steel pipe 303, and then discharged through the connecting pipe 307, the gas and the impeller assembly 306 in the impeller box 304 cooperate to drive the rotating shaft 305 to rotate. The rotating shaft 305 drives the half bevel gear 309 to rotate. The half bevel gear 309 drives the first bevel gear 504 to rotate intermittently. The first bevel gear 504 drives the hollow tube 501 to rotate. When the hollow tube 501 rotates, the water in the upper water-absorbing sponge 503 is thrown out under the action of centrifugal force. At this time, the water in the water-absorbing sponge 503 is thrown onto the heating plate 506 through the water-throwing port 505. The heating plate 506 evaporates the thrown water to generate water vapor. The water vapor floats upward through the conduit 508 and then flows into the filter chamber 206 through the air inlet groove 101, thereby effectively disinfecting some bacteria in the air. The thrown water falls evenly onto the heating plate 506, effectively improving the steam generation efficiency.

[0041] When the heating plate 506 is in a continuous power supply state, the temperature rise of the heating plate 506 causes the water on the upper side of the water-absorbing sponge 503 to heat up, thereby effectively improving the efficiency of water vapor generation. In addition, the frustum-shaped heating plate 506 facilitates the slow evaporation of water that has not evaporated instantly, thereby effectively increasing its steam generation rate and thus effectively improving the disinfection efficiency of bacteria in the air.

[0042] When the half bevel gear 309 is not meshed with the first bevel gear 504, the hollow tube 501 stops rotating. At this time, the water-absorbing sponge 503 absorbs water in the water chamber 4 through multiple water-absorbing grooves 502, and recycles the water in the water chamber 4, effectively preventing the water level in the water chamber 4 from rising and affecting the filtration effect of the filter plate 2.

[0043] Example 3: Reference Figure 2 and Figure 4A multi-environment indoor air disinfection device is basically the same as that in Embodiment 1, but further, the adsorption component includes a filter box 6 fixed inside the disinfection box 1. Multiple air inlets 601 are arranged at equal intervals between the filter box 6 and the second cavity 114. A second partition 602 is fixedly connected inside the filter box 6. A water removal box 603 matching the air inlets 601 is provided between the second partition 602 and the filter box 6. A first exhaust pipe 605 and a second exhaust pipe 606 are fixedly connected to the output end of the filter box 6. Multiple activated carbon plates 604 are provided on the side of the second partition 602 away from the water removal box 603.

[0044] The gas in the second chamber 114 enters the filter box 6 through the air inlet 601. As the gas comes into contact with the water in the water chamber 4, it contains a lot of moisture. The water in the gas reacts with the calcium oxide in the water removal box 603 to generate a lot of heat. The heat generated facilitates secondary disinfection of bacteria in the air, thereby effectively improving the disinfection effect of indoor air. Then, the multi-layer activated carbon plate 604 adsorbs the small molecule bacterial impurities remaining in the air, thereby further improving the disinfection effect of the air. The disinfected gas is discharged through the first exhaust pipe 605 and the second exhaust pipe 606.

[0045] It should be noted that the water box 603 contains a large amount of calcium oxide particles.

[0046] Example 4: Reference Figure 5 and Figure 6 A multi-environment indoor air disinfection device is basically the same as that in Example 1. Furthermore, multiple water guide blocks 201 are fixedly connected to the filter plate 2, and multiple water guide grooves 203 are equidistantly opened on both sides of the water guide blocks 201.

[0047] An arc-shaped groove 204 is provided on the water guide block 201.

[0048] Multiple water guide plates 202 that match the arc-shaped groove 204 are fixedly connected to the water guide block 201.

[0049] Multiple sets of equidistantly arranged triangular blocks 205 are fixedly connected to the filter plate 2.

[0050] When air and water vapor enter the filter chamber 206 through the air inlet groove 101, part of the air and water vapor are directly filtered through the upper side of the filter plate 2, and the remaining water vapor and air flow from top to bottom. At this time, water vapor produces water droplets after contacting the filter plate 2, and the water droplets on the filter plate 2 are caused to flow downward with the downward flow of air. The water droplets wash away the dust and impurities on the filter plate 2 downward, thereby effectively preventing the filter plate 2 from being severely blocked and affecting its air intake effect.

[0051] When the water droplets carrying dust and impurities flow downwards, they come into contact with the triangular baffle 205 and flow to both sides. Under the action of the wind, they flow onto the water guide plates 202 on both sides. At this time, the water droplets carrying impurities flow onto the water guide block 201 through the water guide groove 203, and then flow downwards into the water cavity 4 through the arc-shaped groove 204, thereby effectively preventing dust and impurities from clogging the filter plate 2.

[0052] Example 5: Refer to Figure 2 , Figure 3 , Figure 4 and Figure 8 A multi-environment indoor air disinfection device is basically the same as that in Embodiment 1, but further wherein a first drug storage chamber 108 and a second drug storage chamber 109 are provided between the first fixed plate 112 and the disinfection box 1, a first partition 107 is fixedly connected between the first drug storage chamber 108 and the second drug storage chamber 109, a first exhaust pipe 605 is connected to the first drug storage chamber 108, and a second exhaust pipe 606 is connected to the second drug storage chamber 109.

[0053] A sliding plate 105 is slidably connected to the first partition 107, and the sliding plate 105 slides between the filter box 6 and the disinfection box 1. An electric telescopic rod 104 is fixedly connected inside the disinfection box 1. A drive plate 106 is fixedly connected to the output end of the electric telescopic rod 104, and the drive plate 106 is fixedly connected to the sliding plate 105.

[0054] When disinfecting a sealed room, close the solenoid valve in the second exhaust pipe 606 and open the solenoid valve in the first exhaust pipe 605. At this time, the gas in the filter box 6 flows through the first exhaust pipe 605 into the first drug storage chamber 108 and comes into contact with the chlorine dioxide disinfectant in the first drug storage chamber 108, thereby effectively disinfecting the sealed indoor air. After disinfection, you can enter normally after opening the window for ventilation for a period of time.

[0055] When disinfecting an occupied indoor space, the solenoid valve in the first exhaust pipe 605 is closed and the solenoid valve in the second exhaust pipe 606 is opened. At this time, the gas in the filter box 6 enters the second drug storage chamber 109 through the second exhaust pipe 606 and comes into contact with the slightly acidic hypochlorous acid disinfectant in the second drug storage chamber 109 for disinfection, thereby disinfecting indoor air in multiple environments.

[0056] The sliding plate 105 is driven to slide by the electric telescopic rod 104. When disinfecting the sealed room, the sliding plate 105 is sealed to the upper end of the second medicine storage chamber 109. When disinfecting the room where people are, the sliding plate 105 is sealed to the upper end of the first medicine storage chamber 108.

[0057] Example 6: Refer to Figure 2 and Figure 3An indoor air disinfection device for multiple environments is basically the same as that in Example 1, but further, a filter screen 404 is provided between the inclined plate 401 and the bottom of the disinfection box 1, and the rotating shaft 305 rotates on the filter screen 404 in a sealed manner.

[0058] A mesh plate 402 is symmetrically and fixedly connected between the water chamber 4 and the heating box 5. A filter layer 403 is fixedly connected between the two mesh plates 402, and the rotating shaft 305 passes through the two mesh plates 402.

[0059] A jet pipe 308 is fixedly connected to the end of the connecting pipe 307 away from the impeller box 304. The jet pipe 308 is matched with the mesh plate 402 on the side near the water chamber 4.

[0060] The water in the water cavity 4 is filtered through the filter layer 403, which effectively prevents the sewage in the water cavity 4 from affecting the heating effect of the heating plate 506 and the water absorption effect of the water-absorbing sponge 503.

[0061] The water falls from the filter plate 2 and the water guide block 201 into the water cavity 4. The sealing plate 111 causes the floating impurities to float on the lower side of the first cavity 113 and the lower side of the filter cavity 206. Then, the ultraviolet lamp 110 performs thorough sterilization and disinfection, thereby effectively improving the disinfection effect of indoor air and effectively preventing floating impurities from flowing onto the filter layer 403 and affecting its filtration effect.

[0062] Small dust particles in the water chamber 4 are filtered by the filter screen 404, effectively preventing the filter layer 403 from becoming clogged.

[0063] Water discharged from the connecting pipe 307 is sprayed onto the surface of the filter layer 403 and the mesh plate 402 through the jet pipe 308, blowing off the attached dust and thus effectively preventing the filter layer 403 from clogging.

[0064] The gas ejected from the jet pipe 308 generates multiple small bubbles in the water cavity 4 below the inclined plate 401, thereby effectively increasing the contact area between the gas and the water in the water cavity 4, thus effectively improving the efficiency of heat exchange with the gas in the first cavity 113, and allowing the water vapor in the first cavity 113 to enter the water cavity 4 for recycling. The temperature in the water cavity 4 gradually rises, thereby reducing the heat absorption efficiency of the water in the absorbent sponge 503, and thus effectively improving the steam generation efficiency in the heating box 5.

[0065] The small bubbles ejected from the jet pipe 308 flow along the inclined plate 401 into the second cavity 114, and then are broken up and reduced in size by the filter screen 404. The bubbles can also wash away small impurities attached to the filter screen 404, thereby effectively preventing the filter screen 404 from clogging.

[0066] Example 7: Refer to Figure 1 , Figure 4 and Figure 7A multi-environment indoor air disinfection device is basically the same as that in Embodiment 1. Further, a baffle 7 is fixedly connected to the side of the disinfection box 1 near the air inlet slot 101. A return channel 701 is provided at the end of the baffle 7 away from the disinfection box 1. Support rods 702 are symmetrically fixedly connected to both sides of the baffle 7. The end of the support rod 702 away from the baffle 7 is located in the filter chamber 206. A return pipe 703 communicating with the return channel 701 is opened in the support rod 702.

[0067] When steam flows through conduit 508 to air inlet 101, baffle 7 prevents steam from flowing into the air, thus effectively improving the utilization rate of steam. A small amount of steam comes into contact with baffle 7, generating some water droplets. The water droplets flow along baffle 7 into return trough 701, and then flow into filter chamber 206 through return pipe 703. At the same time, the water flows into water chamber 4 under the action of pump group 3 in first chamber 113, and a small amount of water flows directly onto filter plate 2, which facilitates the removal of impurities on filter plate 2 and causes them to fall into water chamber 4, thereby facilitating the disinfection of bacteria on water chamber 4 by ultraviolet lamp 110, and thus effectively improving the efficiency of indoor air disinfection.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
