When the main stainless steel filter is blocked, the gas in the pre-filter box will be transported through the auxiliary transfer vertical pipeline. The gas will gradually push the piston downward, causing the trigger block on the bottom of the piston to press the warning switch. When the warning switch is pressed, the alarm will be controlled to warn, reminding the staff that the pre-filter needs to be cleaned. The components in the pre-filter mechanism and the main filtering and purification mechanism will be cleaned, and at the same time, the piston will move down to the bottom of the auxiliary transfer transverse pipe, so that the gas can enter the main transfer pipe through the auxiliary transfer transverse pipe, the second one-way valve and the auxiliary stainless steel filter. The gas will be preliminarily filtered through the auxiliary stainless steel filter and then transported to the bottom of the isolation cover for further filtration. In this way, within the short time when the main stainless steel filter is blocked, the gas inside the clean room body can also be filtered and purified step by step without direct shutdown processing, which reserves sufficient time for the staff to clean the components in the pre-filter mechanism and the main filtering and purification mechanism, ensuring the purification effect while avoiding damage to the fan body.

The inner wall of each pre-filter box 301 is fixedly connected with a main stainless steel filter 302. The gas transported to the pre-filter box 301 can be preliminarily treated by the main stainless steel filter 302. The bottom of each pre-filter box 301 is connected to the main transfer pipe 303. A first one-way valve 304 is installed inside each main transfer pipe 303. The gas treated by the main stainless steel filter 302 will be transported to the next-level purification treatment component through the main transfer pipe 303, and the first one-way valve 304 can be set to avoid gas backflow. A first sealing cover plate 305 is installed on the top of each pre-filter box 301. Removing the first sealing cover plate 305 from the top of the pre-filter box 301 can facilitate the cleaning of the clogged main stainless steel filter 302.

[0026] like Figure 1-7As shown, the saturation warning mechanism 4 includes an auxiliary transfer vertical pipe 401 installed on the inner wall of the two pre-filter boxes 301 and two auxiliary transfer transverse pipes 406 connected to one side of the auxiliary transfer vertical pipe 401. When the main stainless steel filter 302 is saturated, the gas cannot continue to be transported downward through the main stainless steel filter 302. At this time, the gas can be transported through the auxiliary transfer vertical pipe 401. The output ends of the two auxiliary transfer transverse pipes 406 are respectively connected to the inner walls of the two main transfer pipes 303. The interior of each auxiliary transfer transverse pipe 406 is connected to the inner wall of the two main transfer pipes 303. A second one-way valve 407 and an auxiliary stainless steel filter 408 are installed. The second one-way valve 407 can prevent the gas in the main transfer pipeline 303 from entering the auxiliary transfer horizontal pipeline 406, thereby achieving the effect of one-way gas transportation. The auxiliary stainless steel filter 408 can be used to preliminarily filter the gas transported in the auxiliary transfer horizontal pipeline 406. The bottom of each auxiliary transfer vertical pipeline 401 is fixedly connected with an early warning switch 402 and a spring 403. The spring 403 is sleeved on the outside of the early warning switch 402, and the top of each spring 403 is A piston 404 is fixedly connected to the auxiliary transfer vertical pipeline 401 for sliding connection. A trigger block 405 adapted to the warning switch 402 is fixedly connected to the bottom surface of each piston 404. Alarms 409 are installed on both sides of the inner wall of the clean room body 1. The two warning switches 402 are electrically connected to the two alarms 409 respectively. When the gas is transported through the auxiliary transfer vertical pipeline 401, the gas will push the piston 404 downward to move. When the piston 404 moves downward, the trigger block 405 will squeeze the warning switch 402, and the piston 404 will move downward to the auxiliary transfer vertical pipeline 401. The auxiliary transfer transverse pipe 406 is moved below the auxiliary transfer vertical pipe 401, so that the gas in the auxiliary transfer vertical pipe 401 can be transported to the main transfer pipe 303 through the auxiliary transfer transverse pipe 406. In this way, when the main stainless steel filter 302 is saturated, the gas can be normally primary filtered in a short time. When the main stainless steel filter 302 is saturated, it means that a lot of dust and impurities have been filtered, and the next-level filter component will also be saturated, which can play a warning effect and facilitate timely cleaning and maintenance of the filter components in the device.

[0027] like Figure 1-7As shown, the main filtering and purification mechanism 5 includes a main filtering box 501 fixedly connected to both sides of the outer surface of the clean room body 1, and the auxiliary transfer transverse pipe 406 is located inside the main filtering box 501. The inner bottom wall of each main filtering box 501 is fixedly connected with an isolation cover 502. The bottom end of the main transfer pipe 303 passes through the main filtering box 501 and extends to the inner bottom of the isolation cover 502, which defines the position of the bottom end of the main transfer pipe 303, so that the gas can stay in the isolation cover 502 for a longer time, and the gas transported through the main transfer pipe 303 The gas will be gradually transported upward from the bottom of the isolation cover 502. The top of each isolation cover 502 is fixedly connected to a HEPA filter 503. The outer surfaces of the two main transfer pipes 303 are respectively fixedly connected to the inner walls of the two HEPA filters 503, which defines the positional relationship of the main transfer pipes 303 and can easily achieve the effect of step-by-step purification and filtration. The inner wall of each isolation cover 502 is fixedly connected to a plurality of arc-shaped sheets 504. The inner bottom wall of each main filter box 501 is installed with four ultraviolet lamps 505. The arc-shaped piece 504 can slow down the upward transmission rate of the gas in the isolation cover 502, so that the ultraviolet lamp 505 can irradiate and sterilize the gas more comprehensively. The bottom surface of each main filter box 501 is installed with a second sealing cover plate 506 by bolts. The second sealing cover plate 506 is removed from the bottom surface of the main filter box 501 to facilitate the cleaning of dust and other particles accumulated inside the isolation cover 502. The eight ultraviolet lamps 505 are respectively located at the four corners of the two isolation covers 502, limiting the ultraviolet lamps 5 05, the gas can be irradiated more comprehensively, thereby optimizing the sterilization effect. The outer surface of each isolation cover 502 is fixedly connected with a breathable mesh frame 507, and the inner wall of each breathable mesh frame 507 is filled with a coconut shell activated carbon layer 508 and a molecular sieve layer 509. A detachable third sealing cover plate 510 is installed on the side away from each other of the two main filter boxes 501. The third sealing cover plate 510 can be removed from the main filter box 501, and then the components inside the main filter box 501 can be cleaned regularly.

[0028] like Figure 1-7As shown, the air conditioning system 6 includes air conditioning bodies 601 installed on both sides of the outer surface of the clean room body 1. The air conditioning body 601 is an existing device, and its working principle and internal structure are not described in detail herein, nor are they excessively limited. Two connecting pipes 602 are installed at the top of each air conditioning body 601, and the tops of the four connecting pipes 602 are respectively connected to the interior of the two main filter boxes 501. The output ends of the two air conditioning bodies 601 are both located inside the clean room body 1. A third one-way valve 603 is installed at the output end of each air conditioning body 601. Two symmetrical sensor array assemblies 604 are installed on the inner top wall of the clean room body 1. The third one-way valve 603 can be set to prevent the gas inside the clean room body 1 from directly entering the interior of the air conditioning body 601, so as to ensure that a closed-loop purification mechanism can be formed to optimize the effect of purifying the gas inside the clean room body 1. A control mechanism 7 is installed on the inner wall of the clean room body 1. The control mechanism 7 includes a fixed connection A power module 702, an ARM architecture chip 703 and a wireless communication module 704 are installed on the inner wall of the controller body 701 on the inner wall of the clean room body 1. The power module 702 and the wireless communication module 704 are electrically connected to the ARM architecture chip 703. The fan body 201, the early warning switch 402, the air conditioner body 601 and the sensor array assembly 604 are electrically connected to the ARM architecture chip 703 through the wireless communication module 704. The air conditioner body 601 can be conveniently controlled to adjust the cooling, heating, humidification or dehumidification working mode according to the temperature and humidity changes inside the clean room body 1 to maintain the best environmental conditions. A sealed door 8 is installed on the outer surface of the clean room body 1. Two symmetrical transparent windows 9 are inlaid on the outer surface of the clean room body 1. The sealed door 8 is located between the two transparent windows 9. The situation inside the clean room body 1 can be observed in real time through the transparent window 9, and the inside of the clean room body 1 can also be entered through the sealed door 8.

[0029] Working principle: When the fan body 201 is started, the gas inside the clean room body 1 can be sucked into the pre-filter box 301 through the air suction port 202 and the air supply duct 203, and then the gas is initially filtered through the main stainless steel filter 302. The filtered dust particles will remain in the main stainless steel filter 302, and then the gas will be transported to the isolation cover 502 through the main transfer pipeline 303 for secondary filtration and purification. The first one-way valve 304 can be set to avoid gas backflow. The gas will be transported upward in the isolation cover 502. During the upward transportation process, it will be blocked by the arc sheet 504, so that the gas can stay in the isolation cover 502 for a longer time, so that the gas can be more full. The air is then irradiated with ultraviolet light 505 to optimize the sterilization effect. Then, the gas passes through the HEPA filter 503 to filter out particles with smaller diameters. Some particles fall to the bottom of the isolation cover 502. The gas filtered by the HEPA filter 503 is transported to the top of the main filter box 501 and then transported downward. During the downward transportation, the gas passes through the coconut shell activated carbon layer 508 and the molecular sieve layer 509 for chemical adsorption, which can adsorb organic volatiles and odor gases in the gas and optimize the quality of air purification. Finally, the gas is transported to the air conditioner body 601 for processing through two connecting pipes 602. At this time, the sensor array component 604 can monitor the temperature and humidity of the internal environment of the clean room body 1 in real time and transmit the signal The signal is fed back to the ARM architecture chip 703 through the wireless communication module 704, and the working mode of the air-conditioning body 601 is controlled by the ARM architecture chip 703. The air-conditioning body 601 can heat, cool, humidify or dehumidify the gas. The specific working mode needs to be switched according to the internal environment of the clean room body 1. Finally, the processed gas will be input into the interior of the clean room body 1 through the third one-way valve 603 installed at the output end of the air-conditioning body 601, realizing a closed-loop purification feedback mechanism. After working for a long time, the main stainless steel filter 302 will be blocked by dust and normal air filtration will not be possible. At this time, the gas will be transported through the auxiliary transfer vertical pipe 401, and a large amount of gas will gradually push the piston 404 moves downward. When the piston 404 moves downward, the trigger block 405 will squeeze the warning switch 402. When the warning switch 402 is squeezed, the alarm 409 will be controlled to perform a warning operation, so that the staff will know that the main stainless steel filter 302 is in a saturated state. The piston 404 will move to the bottom of the auxiliary transfer transverse pipe 406 under the push of the gas, so that the gas will be transported to the main transfer pipe 303 through the auxiliary transfer transverse pipe 406 and the second one-way valve 407, and can also be preliminarily filtered through the auxiliary stainless steel filter 408. In this way, when the main stainless steel filter 302 is saturated, the gas can be filtered normally step by step in a short time to avoid damage to the fan body 201.At the same time, it also provides the staff with sufficient time to clean and maintain the components in the pre-filter mechanism 3 and the main filter purification mechanism 5, which is more practical.
