Detailed Embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides as Figures 1-4An air purification device for clean room decoration as shown, which includes a machine body 1. A suction fan 2 is fixedly arranged on the side of the machine body 1. An air outlet 16 is formed on one side of the machine body 1 away from the suction fan 2. A filtering component is arranged inside the machine body 1. After starting the suction fan 2, the air in the room mixed with particulate dust is sucked into the machine body 1, filtered by the filtering component, and then discharged from the air outlet 16, thereby purifying the air.

[0026] Considering that after the suction fan 2 sucks the air mixed with particulate dust, the particulate dust will generate a certain impact force on the fan blades of the suction fan 2 under the push of the wind pressure, resulting in easy wear of the fan blades of the suction fan 2 and reducing the service life of the suction fan 2. Therefore, in the present utility model, an auxiliary box 3 is arranged on the side of the suction fan 2 away from the machine body 1 through a fixing component. The machine body 1, the suction fan 2 and the auxiliary box 3 are interconnected. An air inlet 4 is formed on one side of the auxiliary box 3 away from the suction fan 2. A baffle 5 is fixedly arranged in the middle of the inside of the auxiliary box 3. There is a gap between the lower end of the baffle 5 and the inner wall of the bottom of the auxiliary box 3. A water tank 6 is fixedly arranged on the top of the auxiliary box 3. A water pump 7 is arranged inside the water tank 6. A shunt pipe 8 is fixedly arranged on the inner wall of the top of the auxiliary box 3. The shunt pipe 8 is interconnected with the water pump 7 through a connecting pipe. A plurality of uniformly arranged and distributed spray heads 9 are fixedly arranged on the side of the shunt pipe 8 close to the baffle 5. A drain pipe is arranged at the bottom of the auxiliary box 3.

[0027] Specifically, start the water pump 7, convey water to the shunt pipe 8 through the connecting pipe, and then spray it out through the spray heads 9 onto the baffle 5, so that there is a thin water curtain on the side of the baffle 5 facing the air inlet 4. When the suction fan 2 is started, the external air mixed with particulate dust enters the auxiliary box 3 through the air inlet 4 and then flows through the bottom of the baffle 5 to the suction fan 2. Since the air passing through the air inlet 4 has a certain speed, the particulate dust in the air impacts on the baffle 5. Because there is flowing water curtain on the baffle 5, the particulate dust in the air is adhered and absorbed, and then flows down to the bottom of the auxiliary box 3 along with the water and is discharged to the external collection box through the drain pipe. After filtering the water inside the collection box, it can be reused. Thus, the particulate dust entrained by the air passing through the suction fan 2 is greatly reduced, avoiding the problem that the particulate dust will generate a certain impact force on the fan blades of the suction fan 2 under the push of the wind pressure, resulting in easy wear of the fan blades of the suction fan 2 and reducing the service life of the suction fan 2.

[0028] In addition, through the setting of the baffle 5 and the water curtain, the air is preliminarily purified, reducing the purification burden of the filtering component inside the machine body 1 and avoiding the problem of frequent replacement of the filtering component.

[0029] Furthermore, the outlet of the spray head 9 is in a flat rectangular shape structure. With this setting, it is convenient for the water sprayed by the spray head 9 to evenly cover the surface of the baffle 5, avoiding the appearance of dead corners in the water curtain.

[0030] Further, the fixing component includes a fixing plate 11 and a bolt 12. The fixing plate 11 is fixedly arranged at the middle of the upper and lower surfaces of the auxiliary box 3. An extension plate is fixedly arranged at the bottom and top of the fixing plate 11. The bolt 12 is threadedly connected to the extension plate. One end of the bolt 12 movably passes through the extension plate and is fixedly provided with a pressing plate 13. The pressing plate 13 is made of soft rubber material. After the auxiliary box 3 and the exhaust fan 2 are mutually attached, rotate the bolt 12 to make the pressing plate 13 displace towards the exhaust fan 2, thereby clamping the exhaust fan 2 and fixedly installing the auxiliary box 3. When it is necessary to repair the exhaust fan 2, reverse-rotate the bolt 12 to separate the auxiliary box 3 and the exhaust fan 2, which is convenient for the disassembly and assembly of the auxiliary box 3.

[0031] In order to improve the sealing performance between the auxiliary box 3 and the exhaust fan 2, a rubber plate 10 fixed on the auxiliary box 3 is arranged between the mutually approaching surfaces of the auxiliary box 3 and the exhaust fan 2, thereby preventing the unpurified air from entering the exhaust fan 2 through the connection seam between the auxiliary box 3 and the exhaust fan 2.

[0032] Further, the filtering component includes a filter plate 14 and an activated carbon plate 15 located behind the filter plate 14. The filter plate 14 and the activated carbon plate 15 are symmetrically distributed about the central axis of the machine body 1. Two insertion holes for the filter plate 14 and the activated carbon plate 15 to pass through are opened at the top of the machine body 1. Clamping plates are fixedly arranged at the tops of the filter plate 14 and the activated carbon plate 15. The clamping plates and the insertion holes are mutually engaged. A handle is fixedly arranged at the top of the clamping plate. Through the installation of the filter plate 14, the air is further filtered. Through the installation of the activated carbon plate 15, the toxic and odorous substances in the air are removed. When it is necessary to replace or clean the filter plate 14 and the activated carbon plate 15, pull the handle to pull the filter plate 14 and the activated carbon plate 15 out of the corresponding insertion holes, improving the convenience of the device.

[0033] Considering that when the device is moved, the ground may be uneven, causing the device to jolt, resulting in the loosening of the filter plate 14 and the activated carbon plate 15, and reducing the sealing performance of the connection between the filter plate 14, the activated carbon plate 15 and the body 1. Therefore, a limiting component for limiting the filter plate 14 and the activated carbon plate 15 is provided on the inner wall of the bottom of the body 1. The limiting component includes two limiting plates 19, which are fixedly arranged on the inner wall of the bottom of the body 1. The two limiting plates 19 are respectively in movable contact with the mutually remote surfaces of the filter plate 14 and the activated carbon plate 15. A sliding groove is provided on the inner wall of the bottom of the body 1 between the filter plate 14 and the activated carbon plate 15. An adjusting groove is also fixedly arranged in the structural layer of the inner wall of the bottom of the body 1. The sliding groove and the adjusting groove are communicated with each other. A driving rod 20 is rotatably arranged in the adjusting groove. A double-thread is arranged on the outer ring of the driving rod 20 located inside the sliding groove. Two movable plates 21 symmetrically distributed about the center line of the sliding groove are movably arranged in the sliding groove. Opposite internal threads are respectively arranged on the two movable plates 21. The two internal threads are respectively in cooperation with the double-thread. One end of the driving rod 20 that movably extends out of the body 1 is fixedly provided with a handle.

[0034] Specifically, rotate the handle to drive the driving rod 20, drive the relative displacement of the two movable plates 21, and through the cooperation of the limiting plates 19, the filter plate 14 and the activated carbon plate 15 are clamped, avoiding the problem that the sealing performance of the connection between the filter plate 14, the activated carbon plate 15 and the body 1 is reduced due to vibration caused by jolting of the device.

[0035] Furthermore, pulleys 18 are rotatably arranged at the four corners of the bottom of the body 1, and a push handle 17 is fixedly arranged at the edge near the top of the body 1. Through the installation of the push handle 17 and the pulleys 18, it is convenient to push and displace the device to purify the air at different positions indoors, reducing the labor of manual handling.
