Description

Technical Field

[0001] This utility model relates to the field of air sterilizer technology, specifically a multi-duct air sterilizer. Background Technology

[0002] Air purifiers are machines that disinfect the air through filtration, purification, and sterilization. Besides killing bacteria, viruses, mold, and spores, some models can also remove organic pollutants such as formaldehyde and phenol from indoor air, and can even kill or filter allergens like pollen. They also effectively remove smoke and odors from cigarettes, unpleasant odors from bathrooms, and body odor. The disinfection effect is reliable, and they can operate even when people are present, allowing for coexistence between people and the machine.

[0003] According to the patent application published on the patent website, "A plasma air sterilizer with multiple air ducts (Publication No.: CN213599537 U; Application No.: 202022206163.9)," the above application addresses the problem that "most existing plasma air sterilizers adopt a single impeller and single air duct structure, with single-sided air intake and single-sided air exhaust. Some adopt a single-sided air intake and bidirectional air exhaust or a bidirectional air intake and single-sided air exhaust structure. In order to further reduce noise and improve purification efficiency, a dual-air duct structure combining two or more impellers is adopted. However, if two or more impellers and air ducts are simply superimposed on the plane and in space, it is easy to cause poor purification effect and high noise." The application optimizes the sterilizer in the above application, but only optimizes the internal air duct structure of the sterilizer. It cannot divert the airflow at the air intake of the sterilizer, resulting in a single air sterilizer working in one place. It cannot achieve unified sterilization of the reset space, which is inconvenient to use. Utility Model Content

[0031] This utility model provides a technical solution: Example 1

[0032] Combination Figures 1 to 5 A multi-duct air sterilizer includes a sterilizer body 3, a base 4 fixedly connected to the bottom of the sterilizer body 3, an air inlet 31 fixedly connected to the top front side of the sterilizer body 3, an air outlet 32 ​​fixedly connected to the bottom outer side of the sterilizer body 3, a disassembly and assembly mechanism 1 provided on the front side of the sterilizer body 3, and a diversion mechanism 2 provided on the front side of the disassembly and assembly mechanism 1.

[0033] The disassembly and assembly mechanism 1 includes a closing component 11, a support component 12, a fixing component one 13, and a fixing component two 14. The closing component 11 is located on the front side of the main body 3 of the disinfection machine, the support component 12 is located on the left and right sides of the closing component 11, and the fixing component one 13 is located on the left and right sides of the main body 3 of the disinfection machine.

[0034] Closing component 11 includes a closing frame 1101, which is positioned at the front of the sterilizer body 3 corresponding to the air inlet 31. Locking rods 1102 are fixedly connected to the left and right sides of the closing frame 1101. Sleeve blocks 1103 are fitted around the outer ring of the locking rods 1102 and are fixedly connected to the left and right sides of the sterilizer body 3. Support component 12 includes a support plate 1201, which is fixedly connected to the front of the sterilizer body 3. The top of the support plate 1201 is flush with the bottom of the closing frame 1101. A support rod 1202 is fixedly connected to the bottom of the support plate 1201 and is fixedly connected to the front of the sterilizer body 3. Fixing component 13 includes a fixing plate 1301, which is fixedly connected to the outer ring of the locking rods 1102. A fixing rod 1202 is fixedly connected to the rear of the fixing plate 1301. A protruding cylinder 1302 is positioned between upper and lower sleeve blocks 1103. A threaded cylinder 1303 is slidably connected to the inner ring of the protruding cylinder 1302. Sliding strips 1304 are slidably connected to the upper and lower sides of the threaded cylinder 1303.

[0035] Furthermore, the closing frame 1101 is located on the front side of the disinfection machine body 3 to seal the air inlet 31. This ensures that when the disinfection machine body 3 is in use, the air inlet 31 can only be drawn through the diversion air duct 2101 on the front side of the closing frame 1101, thus restricting the air intake of the air inlet 31. This facilitates subsequent adjustments by the staff. At the same time, the staff only needs to start the drive motor 1401 to complete the disassembly and assembly of the closing frame 1101, making it convenient for the staff to disassemble and assemble the closing frame 1101 and clean the inside of the closing frame 1101 and the air inlet 31. This will not affect the normal use of the disinfection machine body 3, and the operation is simple and convenient for the staff to use. Example 2

[0036] See Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 Furthermore, based on Embodiment 1, the diversion mechanism 2 includes a duct assembly 21, a connecting assembly 22, a positioning assembly 23, and a diversion assembly 24. The duct assembly 21 is disposed in front of the closing assembly 11, the connecting assembly 22 is disposed on the top of the duct assembly 21, the positioning assembly 23 is disposed in front of the duct assembly 21, and the diversion assembly 24 is disposed in front of the duct assembly 21.

[0037] The air duct assembly 21 includes a diversion air duct outlet 2101, which is fixedly connected to the front side of the closed frame 1101. A closing cover plate 2102 is snapped into the front side of the diversion air duct outlet 2101, and a handle 2103 is fixedly connected to the front side of the closing cover plate 2102. The connecting assembly 22 includes a protrusion 2201, which is fixedly connected to the top of the diversion air duct outlet 2101. A fixing shaft 2202 is fixedly connected to the inner side of the protrusion 2201. A rotating cylinder 2203 is rotatably connected to the outer ring of the fixing shaft 2202. A connecting arm 2204 is fixedly connected to the front side of the rotating cylinder 2203 and is fixedly connected to the top front side of the closing cover plate 2102. The positioning assembly 23 includes a fixing cylinder 2301, which is fixedly connected to the front side of the closing cover plate 2102. At the bottom, a sliding cylinder 2302 is slidably connected inside the fixed cylinder 2301. A compression spring 2303 is fixedly connected inside the top of the sliding cylinder 2302. A positioning rod 2304 is fixedly connected to the bottom of the sliding cylinder 2302. A sleeve plate 2305 is sleeved on the outer ring of the positioning rod 2304. The sleeve plate 2305 is fixedly connected to the front side of the closed frame 1101. A telescopic sliding rod 2306 is fixedly connected inside the top of the sliding cylinder 2302. A pull rod 2307 is fixedly connected to the top of the telescopic sliding rod 2306. The diversion assembly 24 includes a clamp tube 2401. The clamp tube 2401 is clamped to the inner ring of the diversion duct opening 2101. An exhaust pipe 2402 is fixedly connected to the front side of the clamp tube 2401. A clamp 2403 is fixedly connected to the outer ring of the clamp tube 2401. The clamp 2403 is clamped to the inner ring of the outer ring of the diversion duct opening 2101.

[0038] Furthermore: the clamp 2401 is clamped inside the front side of the diversion air duct 2101, and the air intake of the entire air inlet 31 is diverted by the closing cover 2102, so that the main body of the disinfection machine 3 can simultaneously perform exhaust disinfection treatment on multiple points when in use, which is convenient for staff to adapt and plan the use of the main body of the disinfection machine 3. At the same time, when the multiple exhaust pipes 2402 are not needed, the staff can also close the closing cover 2102 to seal the unused diversion air duct 2101. The staff only needs to pull the lever 2307 upward to release the positioning of the closing cover 2102, which is convenient for the staff to disassemble, install and change the position of the multiple slide cylinders 2302. The operation is simple and convenient for the staff to use.

[0039] In actual operation, when this device is in use, when it is necessary to install the closing frame 1101, the staff first snaps the closing frame 1101 onto the front side of the main body 3 of the disinfection machine from front to back, so that the support plate 1201 contacts the bottom of the closing frame 1101 to support the closing frame 1101. At the same time, as the closing frame 1101 moves backward, the protruding cylinder 1302 moves backward and fits onto the outer ring of the threaded shaft 1403, so that the threaded shaft 1403 contacts the threaded cylinder 1303. Then, the staff only needs to start the drive motors 1401 on the left and right sides to drive the threaded shaft 1403 to rotate. The rotation of the threaded shaft 1403 on the left and right sides contacts the threaded cylinder 1303 and drives the threaded shaft 1403 to move backward until the threaded cylinder 1303 moves backward and fits against the inner rear side of the protruding cylinder 1302. At this time, the installation of the closing frame 1101 is completed.

[0040] When installing the exhaust duct 2402, the worker first selects the required branch duct opening 2101, then pulls the lever 2307 on the front side of the branch duct opening 2101 upwards. The upward movement of the lever 2307 drives the positioning lever 2304 upwards via the telescopic slide rod 2306 and the slide cylinder 2302. The upward movement of the positioning lever 2304 disengages from the sleeve plate 2305. Then, the worker pulls the handle 2103 to flip the closing cover 2102 upwards, releasing the closing cover 2102 from the branch duct opening 2101. The worker can then attach the clamp 2401 to the inner ring of the branch duct opening 2101, and with the cooperation of the clamp 2403 attached to the outer ring of the branch duct opening 2101, the installation of the exhaust duct 2402 is completed.
