Through the arrangement of the above structure, the two threaded sleeves 75 will stretch the telescopic plates 1 710 and the telescopic plates 2 711 through the connecting rod 1 712 and the connecting rod 2 713, thereby increasing the time for the gas to reach the filter element 6 from the air inlet pipe 2, thereby avoiding the problem that too much gas contacts the middle part of the filter element 6 at once, making it difficult to remove the chloride ions in the gas.

[0035] An anti-clogging device 8 is provided at one end of the threaded rod 73 away from the dual-axis motor 72, and the anti-clogging device 8 includes a friction wheel 81, and the side of the friction wheel 81 is fixedly connected to the end of the threaded rod 73 away from the dual-axis motor 72. A friction block 82 is penetrated and slidably provided on the top of the cleaning box body 1, and the side of the friction block 82 is fixedly connected to an L-shaped rod 83. The outer wall of the L-shaped rod 83 is slidably connected to the side of the inner wall of the cleaning box body 1, and the inner wall of the L-shaped rod 83 is rotatably connected to a long rod 84, and the outer wall of the long rod 84 is fixedly connected to a brush roller 85. The L-shaped scraper 88 is located on the displacement trajectory of the brush roller 85, and the friction wheel 81 is in contact with the friction block 82. Through the arrangement of the above structure, the movement of the long rod 84 will drive the brush roller 85 to move, and the movement of the brush roller 85 will clean up and drop the impurities on the surface of the filter element 6 to prevent the impurities from affecting the filtering effect of the filter element 6.

[0036] A one-way bearing 86 is fixedly connected to the circumferential surface of the long rod 84, a fixing plate 87 is fixedly connected to the inner wall of the cleaning box body 1, and an L-shaped scraper 88 is fixedly connected to the bottom of the inner wall of the cleaning box body 1. The one-way bearing 86 is in contact with the fixing plate 87. Through the arrangement of the above structure, when the brush roller 85 rotates, the side of the brush roller 85 with impurities will be resisted by the L-shaped scraper 88, so that the L-shaped scraper 88 scrapes off the impurities on the surface of the brush roller 85, thereby preventing the impurities from adhering to the surface of the filter element 6 for the second time.

[0037] During use, after the gas that needs to be cleared of chloride ions enters the cleaning box body 1 from the air inlet pipe 2, the gas first passes through the activated carbon filter layer in the filter element 6 to perform preliminary filtration on the chloride ions, and then passes through the composite high-efficiency filter layer to further filter the chloride ions, and then passes through the silver nitrate filter layer to react with the chloride ions to filter them, and then passes through the antimicrobial filter layer to sterilize the filtered gas, and then passes through the reverse osmosis membrane layer to protect the filtered gas, and finally the filtered gas is discharged from the air outlet pipe 3, and the dual-axis motor 72 is started. The two output shafts of the dual-axis motor 72 cause the two threaded rods 73 to rotate, and the rotation of the two threaded rods 73 will drive the two threaded sleeves 75 to move, and the movement of the two threaded sleeves 75 will respectively drive the connecting plates 76 to move, and the movement of the two connecting plates 76 will drive the moving rod 77 to move along the slide groove at the bottom of the inner wall of the cleaning box body 1, and at the same time, the moving rod 77 will move along the moving groove of the inner wall of the guide block 79, so that the guide block 79 moves along the circular groove of the fixed rod 78. The circumferential surface rotates, and the rotation of the guide block 79 will drive the guide groove 791 to move, so that the gas is guided to the filter element 6 along the guide groove 791 for filtering, thereby ensuring that the filter element 6 filters the chloride ions in the air in an all-round manner, thereby avoiding the accumulation of chloride ions in a local area, which makes it difficult to filter in the local area; when the two threaded sleeves 75 move in opposite directions, the two threaded sleeves 75 will compress the telescopic plate 1 710 and the telescopic plate 2 711 through the connecting rod 1 712 and the connecting rod 2 713, so that when the two guide blocks 79 are dispersed, more gas can flow to the filter element 6 through the guide groove 791 of the guide block 79, and when the two threaded sleeves 75 move in opposite directions, the two threaded sleeves 75 will stretch the telescopic plate 1 710 and the telescopic plate 2 711 through the connecting rod 1 712 and the connecting rod 2 713, thereby increasing the time for the gas to reach the filter element 6 from the air inlet pipe 2, thereby avoiding the problem that too much gas contacts the middle part of the filter element 6 at once, making it difficult to remove the chloride ions in the gas.

[0038] The impurities in the gas will adhere to the filter element 6 when filtering, thereby reducing the filtering effect of the filter element 6. When the two threaded rods 73 rotate forward, they will drive the friction wheel 81 to rotate on the surface of the friction block 82. Under the friction force between the friction wheel 81 and the friction block 82, the rotation of the friction wheel 81 will cause the friction block 82 to move downward. The movement of the friction block 82 will drive the L-shaped rod 83 to move downward. The movement of the L-shaped rod 83 will drive the long rod 84 to move. The movement of the long rod 84 will drive the brush roller 85 to move. The movement of the brush roller 85 will clean up the impurities on the surface of the filter element 6 to prevent the impurities from affecting the filtering effect of the filter element 6. When the long rod 84 moves downward, it will drive the one-way bearing 86 to move. Because the restriction of the one-way bearing 86 , so the long rod 84 cannot rotate when moving. When the long rod 84 drives the brush roller 85 to move to the inner wall of the L-shaped scraper 88, when the two threaded rods 73 reverse, the friction wheel 81 will be driven to reverse, so that the friction block 82 moves upward, and the friction block 82 drives the L-shaped rod 83, the long rod 84, and the brush roller 85 to move upward. The upward movement of the long rod 84 will cause the one-way bearing 86 to rotate on the fixed plate 87, and the rotation of the one-way bearing 86 will cause the long rod 84 to rotate. The rotation of the long rod 84 will drive the brush roller 85 to rotate. When the brush roller 85 rotates, the side of the brush roller 85 with impurities will be resisted by the L-shaped scraper 88, so that the L-shaped scraper 88 will scrape off the impurities on the surface of the brush roller 85, thereby preventing the impurities from adhering to the surface of the filter element 6 for the second time.

The filter element 6 is located on the displacement track of the E-shaped extrusion plate 95. A spring is arranged between the E-shaped extrusion plate 95 and the elongated plate 93. Through the arrangement of the above structure, when the arc surface of the U-shaped block 94 does not contact the arc block 92, the spring will drive the E-shaped extrusion plate 95 to extrude the activated carbon filter layer through its own elastic force, thereby changing the overall structure of the activated carbon inside the activated carbon filter layer, which helps to evenly distribute the flow of air and avoid the problem of too much or too little air flow passing through certain areas.

[0040] When in use, the downward movement of the L-shaped rod 83 will drive the Z-shaped plate 96 to move, and the movement of the Z-shaped plate 96 will drive the U-shaped block 94 to move. The movement of the U-shaped block 94 will drive the long plate 93 to slide on the side of the long plate 91, and the movement of the U-shaped block 94 will drive the E-shaped extrusion plate 95 to move. When the U-shaped block 94 moves, the curved surface of the U-shaped block 94 will contact the curved block 1 92, so that the U-shaped block 94 drives the E-shaped extrusion plate 95 away from the activated carbon filter layer of the filter element 6, and the E-shaped extrusion plate 95 will squeeze the spring. When the curved surface of the U-shaped block 94 does not contact the curved block 1 92, the spring will drive the E-shaped extrusion plate 95 to squeeze the activated carbon filter layer through its own elastic force, thereby changing the overall structure of the activated carbon inside the activated carbon filter layer, which helps to evenly distribute the airflow and avoid the problem of too much or too little air flow passing through certain areas.
