[0033] Embodiment 1

[0034] See also Figure 1-Figure 4 As shown in the figure, a high-efficiency filter structure for a clean room with an oxygenation function includes a filter body 100, an oxygenation device 200 is installed on the top of the filter body 100, an air inlet slot 300 is opened at the front end of the filter body 100, and the inner wall of the filter body 100 is rotatably connected with a rotating shaft 400, and a desiccant layer 500 is installed on the outer side of the rotating shaft 400. The gas to be filtered enters the filter body 100 through the air inlet slot 300 for filtration. At this time, the gas passes through the desiccant layer 500 to be dried and drives the rotating shaft 400 to rotate;

[0035] The filter body 100 is provided with a drying assembly 600 inside, and the drying assembly 600 includes a fixing rod 601, which is located inside the filter body 100, and is fixed to the filter body 100. A hydraulic chamber 602 is fixedly connected to the outside of the rotating shaft 400. When the gas flow rate is too fast, that is, a large amount of gas needs to be filtered at the same time, the rotating shaft 400 can be driven to rotate rapidly, so that the rotating shaft 400 drives the hydraulic chamber 602 fixedly connected thereto to rotate rapidly. The inner wall of the hydraulic bin 602 is slidably connected to the power plate 604 by setting an elastic rod 603, and the outer side of the hydraulic bin 602 is slidably connected to the arc plate 605. There are two arc plates 605 in total, and the two arc plates 605 are distributed in a circular array about the rotating shaft 400. The bottom of the fixed rod 601 is rotatably connected to the rotating rod 612, one side of the rotating rod 612 is fixedly connected to the transmission rod 1 606, and the other side of the rotating rod 612 is fixedly connected to the transmission rod 2 607. The bottom of the transmission rod 1 606 is hinged with a force plate 608, and the force plate 608 is located at the top position of the arc plate 605. The force plate 608 contacts the arc plate 605. The top of the transmission rod 1 606 is fixedly connected to a spring 609, and the top of the spring 609 is fixedly connected to a fixed plate 610. The fixed plate 610 is located at the side position of the fixed rod 601, and the fixed plate 610 and the fixed rod 601 are in a fixed state. When the rotating shaft 400 rotates rapidly, the rotating shaft 400 drives the hydraulic chamber 602 fixedly connected thereto to rotate rapidly. The power plate 604 in the hydraulic chamber 602 then pulls the elastic rod 603 fixedly connected thereto under the action of the centripetal force, and slides in the hydraulic chamber 602, thereby increasing the pressure in the hydraulic chamber 602, driving the arc plate 605 slidably connected to the hydraulic chamber 602 to move, and the arc plate 605 randomly squeezes the force plate 608 and causes it to move, and the force plate 608 randomly drives the transmission rod 1 606 hinged thereto to squeeze the spring 609 and cause it to move. The side of the transmission rod 2 607 is fixedly connected with a positioning plate 611, and the inner side of the positioning plate 611 is bonded with a second desiccant layer 613. When the transmission rod 1 606 moves, in conjunction with the rotating rod 612 fixedly connected to the transmission rod 1 606 and the fixed rod 601 rotatably connected to the rotating rod 612, the transmission rod 2 607 fixedly connected to the rotating rod 612 can be driven to rotate in the opposite direction relative to the transmission rod 1 606, so that the transmission rod 2 607 drives the positioning plate 611 fixedly connected thereto and the desiccant layer 2 613 located on the positioning plate 611 to move downward for drying and dehumidifying the filtered gas, thereby improving the usability of the device in this situation.

[0036] When in use, the gas to be filtered enters the filter body 100 through the air inlet slot 300 for filtration. At this time, the gas passes through the desiccant layer 500 for drying and drives the rotating shaft 400 to rotate. When the gas flow rate is too fast, that is, a large amount of gas needs to be filtered at the same time, the rotating shaft 400 can be driven to rotate quickly, so that the rotating shaft 400 drives the hydraulic chamber 602 fixedly connected thereto to rotate quickly. Then, the power plate 604 in the hydraulic chamber 602, under the action of the centripetal force, pulls the elastic rod 603 fixedly connected thereto to slide in the hydraulic chamber 602, thereby increasing the pressure in the hydraulic chamber 602, driving the arc plate 605 slidably connected to the hydraulic chamber 602 to move, and the arc plate 605 randomly squeezes the force-bearing plate 608 and causes the force-bearing plate 608 to rotate quickly. When it moves, the force-bearing plate 608 randomly drives the transmission rod 1 606 hinged thereto to squeeze the spring 609, thereby moving. In cooperation with the rotating rod 612 fixedly connected to the transmission rod 1 606 and the fixed rod 601 rotatably connected to the rotating rod 612, the transmission rod 2 607 fixedly connected to the rotating rod 612 can be driven to rotate in the opposite direction relative to the transmission rod 1 606, so that the transmission rod 2 607 drives the positioning plate 611 fixedly connected thereto and the desiccant layer 2 613 located on the positioning plate 611 to move downward for drying.

[0037] To further improve the dehumidification effect of the device, please refer to Figure 1-Figure 5 As shown in the figure, an auxiliary component 700 is arranged inside the filter body 100, and the auxiliary component 700 includes a special-shaped rod 701, which is located at the rear end of the fixed rod 601, and the special-shaped rod 701 is fixed to the fixed rod 601. The side of the special-shaped rod 701 is bonded with a desiccant layer 3 702, and the desiccant layer 3 702 and the desiccant layer 2 613 are stacked and flexibly connected. When the desiccant layer 2 613 moves downward for drying, the special-shaped rod 701 fixedly connected to the fixed rod 601 is still in a static state, and the desiccant layer 3 702 stacked and flexibly connected to the desiccant layer 2 613 is connected to the special-shaped rod 701, so that the special-shaped rod 701 completely expands the desiccant layer 3 702, assists in drying, and further improves the drying effect of the device.

[0038] During use, when the second desiccant layer 613 moves downward for drying, the special-shaped rod 701 fixedly connected to the fixed rod 601 remains stationary, while the desiccant layer three 702 stacked with the second desiccant layer 613 and flexibly connected thereto is connected to the special-shaped rod 701, so that the special-shaped rod 701 fully expands the desiccant layer three 702 to assist drying.

[0039] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
