Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to an air purifier for a biological clean room. Background Art

[0002] A biological clean room refers to a clean room where microorganisms in the air are the main control object. Most biological clean room standards use the clean room classification method and then add requirements for microbial control. Biological clean rooms are mainly used in pharmaceutical manufacturing, sterile animal breeding, hospital operating rooms, burn wards, leukemia wards, food production, and high-end cosmetics production.

[0003] In order to ensure the air quality of biological clean rooms, air purifiers are usually installed in the clean rooms. Existing air purifiers usually have air intakes on both sides and are discharged from the top after evolution. When air is taken in, a filter is needed to block hair or large dust particles to prevent them from entering the interior of the purifier. After long-term use, the filter will be clogged. When cleaning the filter, the outer shell needs to be removed and the filter needs to be removed. The overall operation is relatively cumbersome, and the air purifier needs to be suspended when cleaning the filter. In view of this, we propose an air purifier for biological clean rooms. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide an air purifier for a biological clean room, which can solve the problem that the filter cleaning process is relatively complicated.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air purifier for a biological clean room, comprising a purifier body, an outer surface of the purifier body is provided with an air inlet communicated with the interior thereof, an upper surface of the purifier body is provided with an air outlet, an inner wall of the air outlet is provided with a fan, the bottom wall of the purifier body is slidably connected with an annular filter screen, the inner wall of the annular filter screen is provided with teeth, the bottom wall of the purifier body is fixedly connected with a cleaning box, the left surface of the cleaning box is provided with a sliding groove extending from the right surface thereof, the annular filter screen is slidably connected inside the sliding groove, the lower surface of the purifier body is fixedly connected with a bottom plate, the lower surface of the bottom plate is rotatably connected with a driving disk, and a cleaning assembly is provided on the driving disk.

[0006] Preferably, the cleaning assembly includes a driving shaft, which is fixedly connected to the upper surface of the driving disk. The upper end of the driving shaft rotates through the interior of the cleaning box and is rotationally connected to the top wall of the cleaning box. The outer surface of the driving shaft is sleeved with a cleaning roller, the outer surface of the cleaning roller is in contact with the annular filter screen, and the top wall of the cleaning box is rotationally connected to a first gear.

[0007] Preferably, the outer surface of the first gear is meshedly connected with a second gear, and the second gear is sleeved on the outer surface of the driving shaft. A cleaning assembly is also provided inside the cleaning box, and the outer surfaces of the two driving shafts are sleeved with pulleys.

[0008] Preferably, the outer surface transmission sleeves of the two pulleys are provided with belts, the bottom wall of the cleaning box is fixedly connected with a second cleaning box, and the side surface of the second cleaning box close to the cleaning roller is arranged in an arc shape.

[0009] Preferably, a second sliding groove is provided on a surface of one side of the second cleaning box close to the cleaning roller, and a limiting rod is fixedly connected to the inner wall of the second sliding groove.

[0010] Preferably, a lever is slidably sleeved on the outer surface of the limit rod, a water outlet is opened on the left side surface of the second cleaning box, and a baffle is slidably connected to the inside of the water outlet.

[0011] Preferably, an L-shaped connecting rod is fixedly connected to the right side surface of the baffle, and the other end of the L-shaped connecting rod is fixedly connected to the lower surface of the shifting rod.

[0012] Preferably, a return spring is fixedly connected between the lever and the inner wall of the second sliding groove, the outer surface of the cleaning roller is fixedly connected to the second lever, and a roller is arranged on the lower surface of the bottom plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) In the air purifier for biological clean rooms, outside air enters the interior of the purifier body through the air inlet. After entering, the air will first contact the annular filter. When the annular filter becomes dirty after a long period of use, the drive disk can be rotated, and the drive disk can simultaneously use the drive assembly to drive the annular filter to rotate. After the annular filter rotates, the dirty part enters the interior of the cleaning box and is cleaned by the cleaning box. At the same time, the relatively clean annular filter located in the cleaning box slides out for replenishment. Through the above structure, when the annular filter is blocked or dirty, the annular filter can be cleaned without disassembling it. At the same time, the relatively clean part will be seamlessly connected during cleaning, thereby reducing the frequency of disassembling and cleaning the annular filter, thereby improving the practicality of the air purifier.

[0015] (2) In the biological clean room air purifier, after the baffle moves, the obstruction to the water outlet is removed, and the water flows through the water outlet to the outer surface of the cleaning roller, thereby improving the cleaning effect. At the same time, when the cleaning roller rotates, the second cleaning box is used to scrape off the dirt on the surface. Since the lever moves in a straight line, it will be separated from the lever after the second lever drives the lever to move a certain distance, and then reset by the reset spring. At the same time, when a certain area in the clean room urgently needs to be cleaned, the air purifier can be quickly moved to the purification area by the roller. Through the above structure, not only can the cleaning roller be cleaned, but the purifier body can also be quickly moved by the roller, thereby improving the purification effect of the specific area.

When the driving disc 10 rotates, the driving shaft 11 is synchronously driven to rotate. After the driving shaft 11 rotates, the cleaning roller 8 is synchronously driven to rotate, and the second gear 13 is synchronously driven to rotate. After the second gear 13 rotates, the first gear 12 is synchronously driven to rotate, and at this time, the rotation directions of the first gear 12 and the second gear 13 are opposite, so as to increase the relative movement speed. After the cleaning roller 8 rotates, the annular filter screen 5 is cleaned.

When the annular filter screen 5 is dirty after a long period of use, the driving disk 10 can be rotated. The driving disk 10 synchronously uses the driving component to drive the annular filter screen 5 to rotate. After the annular filter screen 5 rotates, the dirty part enters the interior of the cleaning box 7 and is cleaned by the cleaning box 7. At the same time, the relatively clean annular filter screen 5 located in the cleaning box 7 slides out for replenishment. When the driving disk 10 rotates, it will synchronously drive the driving shaft 11 to rotate. After the driving shaft 11 rotates, it will synchronously drive the cleaning roller 8 to rotate.

After the baffle 21 moves, the obstruction to the water outlet 20 is cancelled, and the water flows through the water outlet 20 to the outer surface of the cleaning roller 8, thereby improving the cleaning effect. At the same time, when the cleaning roller 8 rotates, the second cleaning box 16 will be used to scrape off the dirt on the surface. Since the lever 19 moves in a straight line, it will be separated from the lever 19 after the second lever 24 drives the lever 19 to move a certain distance, and then the reset spring 23 is used to complete the reset. At the same time, when a certain area in the clean room is in urgent need of cleaning, the air purifier can be quickly moved to the purification area through the roller 25.
