Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1 - Figure 6 An auxiliary air purification device for a cleanroom includes a ceiling 1 and two bases 11 fixedly installed on the ceiling 1. The ceiling 1 is provided with a replacement component 2 for replacing an external filter. The replacement component 2 facilitates the replacement of the external filter and avoids the filter from being blocked, which would affect the exhaust efficiency. The replacement component 2 is provided with a dust collection component 3, the dust collection component 3 is provided with a cleaning component 4, and the dust collection component 3 is provided with a purification component 5.

[0024] The replacement component 2 includes a mounting groove 21 formed in the ceiling 1, an exhaust pipe 22 fixedly installed in the mounting groove 21, a first chamber 23 and a second chamber 24 formed in the ceiling 1, a first filter screen 25 provided at the lower end of the exhaust pipe 22, connecting blocks 26 fixedly installed at both ends of the first filter screen 25, the first filter screen 25 and the ceiling 1 are interlocked, a fixing groove 27 is formed in the connecting block 26, an arc-shaped block 28 is slidably installed in the fixing groove 27, a spring 29 is provided between the arc-shaped block 28 and the fixing groove 27, and two handles 201 are fixedly installed at the lower end of the first filter screen 25.

[0025] The vacuuming assembly 3 includes a purification box 31 fixedly installed on the upper end of two bases 11. The purification box 31 and the exhaust pipe 22 are welded together and connected. The purification box 31 and the exhaust pipe 22 are connected. A third chamber 32 is opened on the purification box 31. A support plate 33 is fixedly installed on the third chamber 32. A drive motor 34 is fixedly installed on the side wall of the support plate 33. A connecting shaft 35 is fixedly installed at the output end of the drive motor 34. A fan 36 is fixedly installed on the axial side wall of the connecting shaft 35.

[0026] The purification component 5 includes a limiting groove 51 formed on the purification box 31, an activated carbon plate 52 is inserted and installed on the limiting groove 51, the activated carbon plate 52 can purify the gas, and an exhaust pipe 53 is fixedly installed at one end of the purification box 31, the exhaust pipe 53 is connected to the purification box 31.

[0027] The size of the connecting block 26 is the same as that of the first chamber 23. When the connecting block 26 enters the first chamber 23, the arc-shaped block 28 can enter the second chamber 24 through the action of the spring 29, thereby fixing the first filter screen 25.

[0028] In this embodiment: First, holding both handles 201, the first filter screen 25 is placed in contact with the exhaust pipe 22. Then, the two connecting blocks 26 enter the first chamber 23. At this time, the arc-shaped block 28 enters the second chamber 24 through the action of the spring 29, thereby limiting the first filter screen 25, which can prevent the first filter screen 25 from falling and facilitate the replacement of the first filter screen 25. Then, the drive motor 34 is started, so that the output end of the drive motor 34 drives the connecting shaft 35 and the fan 36 to rotate, thereby exchanging the air in the clean room. The dust on the gas is separated by the first filter screen 25. When the first filter screen 25 is covered with dust, it is easy to clean and replace it. Then the gas passes through the second filter screen 41 and comes into contact with the activated carbon plate 52. The activated carbon plate 52 can adsorb harmful impurities in the gas, preventing harmful gases from being directly discharged outdoors. Finally, the purified gas is discharged outdoors through the exhaust pipe 53 to avoid affecting air pollution. The activated carbon plate 52 can be replaced through the maintenance port on the ceiling 1 after a period of use to avoid affecting the purification effect.

[0029] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The cleaning assembly 4 includes a second filter screen 41 fixedly installed on the third chamber 32, a waste bin 42 opened on one of the bases 11, a cleaning rod 43 fixedly installed at one end of the connecting shaft 35, and a brush 44 glued to the side wall of the cleaning rod 43.

[0030] The waste bins 42 are located at both ends of the second filter screen 41. Dust on the second filter screen 41 will fall into the waste bins 42 for collection.

[0031] In this embodiment: the first filter screen 25 can be replaced and cleaned in time when it is outdoors, but how to replace the second filter screen 41 in time inside the purification box 31? When a large amount of dust is adsorbed on the second filter screen 41, the drive motor 34 drives the connecting shaft 35, the sweeping rod 43 and the brush 44 to clean the second filter screen 41 to avoid affecting the filtration effect.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
