Description

Technical Field

[0001] The present invention relates to the technical field of air disinfection and purification devices, and in particular to an air disinfection and purification device for field rescue medical and epidemic prevention cabins. Background Art

[0002] In field rescue scenarios, air purification in medical quarantine shelters is a key component in ensuring medical safety and personnel health. Pathogens such as bacteria, viruses, and fungi are present in the wild, and airborne droplet nuclei can survive for hours. The concentration of patients within the shelters creates a high risk of cross-infection. This requires a purification system that meets medical-grade standards and is combined with ultraviolet disinfection. This safeguards the medical operating environment, while the air supply system prevents external contamination and ensures air freshness. In field rescue scenarios, current air disinfection and purification systems for medical quarantine shelters typically disinfect the air through two-stage filtration combined with ultraviolet lighting, and purify the air through the volatilization of chlorine dioxide gel.

[0003] To maintain high air handling efficiency, high-power centrifugal fans are typically used to increase air flow rates. While the accompanying large air inlet and filter assembly can increase throughput, the limitations of the fan volute structure create a unique laminar flow effect on the filter media surface. Airflow primarily enters through the geometric center of the filter plate, resulting in a higher filtration load in this area. This uneven airflow distribution accelerates the local pressure drop across the filter media. In particular, particles 0.3-5μm in size (such as viral aerosol carriers) can form dense accumulations in the center of the filter plate, causing a local decrease in filter media porosity. When the resistance in the middle of the filter material exceeds the critical value, the airflow will be forced to shift to the edge of the filter plate, resulting in a reduction in the effective filtration area, and ultimately causing the equipment's air volume to attenuate and the filtration efficiency to decrease; when using ultraviolet lighting to disinfect the air, dust in the air will adhere to the surface of the ultraviolet lamp, thereby affecting the effect of ultraviolet lighting disinfection; in order to prevent excessive release of chlorine dioxide gel under optimal temperature and humidity conditions and affect the human body, the concentration of chlorine dioxide gel during configuration ensures that it will not exceed the limit under optimal conditions. This method may result in insufficient concentration of chlorine dioxide gel volatilization under adverse conditions, affecting the disinfection effect. Summary of the Invention

[0042] The disinfection unit 31 is provided with a rotating unit 33, which includes a worm gear 331 fixedly mounted on the outer wall of the screw rod 324 and coaxially rotating therewith, a cross bar 333 fixedly mounted on the front end of the telescopic rod 442 and extending through the blocking plate 313, and a worm 332 fixedly mounted in the middle of the cross bar 333 and meshing with the worm gear 331. The cross bar 333 is fixedly connected to a rotating rod 214.

[0043] The purification mechanism 4 includes a filter portion 41 arranged in the shell 11, and the filter portion 41 includes a grid plate 411 detachably arranged in the shell 11, a plurality of rear mounting blocks 412 fixedly arranged on the grid plate 411, a rear filter plate 413 detachably arranged in the shell 11, and a plurality of rear fixing blocks 414 fixedly arranged on the rear filter plate 413.

[0044] The housing 11 houses a purification unit 42, which includes a purification box 421 fixedly mounted within the housing 11, a fixing slot 423 disposed on the rear wall of the purification box 421, a volatilization box 422 removably mounted within the fixing slot 423, and a volatilization slot 424 disposed within the housing 11 and in front of the volatilization box 422. A blocking plate 313 separates the air to be filtered from the purification unit 42, preventing it from escaping after being filtered by the filter unit 41. The volatilization box 422 is filled with a pre-configured chlorine dioxide gel and is inserted into the fixing slot 423 for installation. The shapes of the grid plate 411 and the rear filter plate 413 match those of the purification box 421, ensuring smooth installation within the housing 11.

[0045] A driving unit 43 is provided in the housing 11, and the driving unit 43 includes a dual-axis motor 432 fixedly provided on the front wall of the volatilization tank 424, a fan 431 provided in the volatilization tank 424 and driven by the dual-axis motor 432, and a spline rod 433 provided on one side of the dual-axis motor 432 and driven by the dual-axis motor 432, wherein the angle of a single rotation of the dual-axis motor 432 is a multiple of ninety degrees, which facilitates the connection of the subsequent transmission unit 44.

[0046] A transmission portion 44 is provided within the housing 11. The transmission portion 44 includes a spline groove 441 provided on one side of the spline rod 433 and cooperating with the spline rod 433, a telescopic rod 442 fixedly provided at the front end of the spline groove 441, a toggle rod 443 rotatably provided on the side wall of the spline groove 441, and a toggle rod 443 extending through a toggle groove 444 provided on the side wall of the housing 11. The toggle rod 443 slides within the toggle groove 444. When the toggle rod 443 is pulled, the telescopic rod 442 is stretched, and the spline rod 433 is inserted into the spline groove 441. To ensure a stable connection, the toggle groove 444 can be provided in an "L" shape. After the toggle rod 443 is pulled until the spline rod 433 is inserted into the spline groove 441, the toggle rod 443 is rotated downward so that the toggle rod 443 is interference-connected with the lower end of the toggle groove 444, or a fixing component can be provided at the toggle groove 444. The toggle rod 443 is fixed.

[0047] The mounting mechanism 1 also includes a plurality of rear mounting slots 14 arranged in the outer shell 11, and an opening fan 16 that is rotatably opened and arranged on the lower wall of the outer shell 11 and cooperates with the filter 315, wherein the rear mounting block 412 and the rear fixing block 414 are both arranged in cooperation with the rear mounting slot 14, and the grid plate 411 and the rear filter plate 413 are both installed through the rear mounting slot 14, and the opening fan 16 is used to discharge dust on the disinfection lamp 314 collected by the filter 315.

[0048] The protection part 12 includes a protection plate 121 detachably arranged in the outer shell 11, a plurality of front mounting blocks 122 fixedly arranged on the protection plate 121, and a plurality of front mounting slots 123 arranged on the outer shell 11 and cooperating with the front mounting blocks 122; the air intake part 15 includes a base 151 fixedly arranged in the outer shell 11, a mounting frame 152 fixedly arranged on the base 151, and a rotating fan 153 arranged on the mounting frame 152, wherein the protection plate 121 slides into the front mounting slot 123 through the front mounting block 122 for installation, and the rotating fan 153 is provided with a starting component for driving, which is an existing mature technology.

[0049] The order of the interior of the housing 11 of the device from front to back is as follows: protective plate 121, front filter plate 13, fixed plate 211, rotating fan 153, disinfection lamp 314, rear filter plate 413, and grid plate 411. The purification box 421 is arranged below the rear filter plate 413 and grid plate 411. Among them, the protective plate 121, rear filter plate 413, and grid plate 411 are all detachable. Dust on the front filter plate 13 can be cleaned by removing the protective plate 121. Dust from the disinfection lamp 314 is collected by the filter 315 and discharged by opening the fan 16.

[0050] The housing 11 is provided with a temperature measuring device and a chlorine dioxide concentration detecting device to understand and grasp the changes in the environment in real time.

[0051] In one embodiment provided herein, the protective plate 121 is first installed through the front mounting slot 123, the grid plate 411 and the rear filter plate 413 are then installed through the rear mounting slot 14, and the volatilization box 422 is installed through the fixing slot 423. When an external detection device detects that the concentration of the volatilized chlorine dioxide gel is insufficient, the dual-axis motor 432 is started, and the fan 431 rotates in the volatilization slot 424, accelerating the airflow and thereby improving the volatilization effect of the chlorine dioxide gel. This device can improve the volatilization effect of the chlorine dioxide gel according to actual conditions when in adverse conditions.

[0052] When the disinfection lamp 314 has a poor disinfection effect on the air, the toggle rod 443 is pulled to extend the telescopic rod 442. At this time, the toggle rod 443 is located in the toggle slot 444 and slides. After the spline rod 433 is inserted into the spline slot 441, the toggle rod 443 is limited and the dual-axis motor 432 is started. The cross bar 333 follows the spline rod 433 to rotate back and forth. The rotation of the cross bar 333 drives the worm 332 to rotate back and forth, so that the worm gear 331 rotates and drives the screw rod 324 to rotate back and forth. Since the screw rod 324 is threadedly connected to the movable plate 322, the reciprocating rotation of the screw rod 324 drives the movable plate 322 to move up and down, and the cleaning ring 321 is located on the outer wall of the disinfection lamp 314 and moves up and down, wiping the dust on it so that it falls into the filter 315 and is then discharged by opening the fan 16. When the ultraviolet lamp is blocked by dust, the outer wall of the ultraviolet lamp can be cleaned to ensure the effect of ultraviolet irradiation disinfection;

[0053] By the reciprocating rotation of the cross bar 333 following the spline rod 433, one gear 212 rotates, driving the ring gear 221 to rotate. Since the ring gear 221 is engaged with the other three gears 212, the other three gears 212 also rotate in the same direction as the gear 212, so that the four racks 223 approach or move away from each other, and the elastic cloth 224 is intermittently in an open and contracted state, thereby periodically blocking the center of the front filter plate 13, so that the airflow periodically passes through the center and surrounding areas of the front filter plate 13. This device avoids dust from concentrating in the center of the front filter plate 13, thereby causing blockage and affecting the filtering effect.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any person skilled in the art may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
