[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A filter is a device used to filter impurities in air or liquid. It is usually made of fine mesh material and has a filtering effect. Filters are widely used in household appliances, industrial equipment, automobiles and other fields to remove dust, particulate matter, bacteria and other harmful substances in the air, or to filter out impurities during liquid processing to ensure the normal operation of equipment or product quality.

[0023] Based on the technical defects of the prior art that there is a gap between the filter screen 5 and the opening 11 of the cover plate 1 after installation, which affects the filtering effect, please refer to Figure 1-Figure 4 The filter screen 5 is adjusted and connected by the fixing rod 34 through the fixing mechanism 32, and the fixing rod 34 is connected to the fixing mechanism 32 through the fixing mechanism 34. The fixing rod 34 is connected to the fixing mechanism 32 through the fixing mechanism 34, and the fixing rod 34 is connected to the fixing mechanism 32 through the fixing mechanism 34. The fixing rod 34 is connected to the fixing mechanism 32 through the fixing mechanism 34, and the fixing rod 34 is connected to the fixing mechanism 34 through the fixing mechanism 34.

[0024] To prevent the medium from flowing through the gap between the opening 11 and the two ends of the filter screen 5, please refer to Figure 3 The side pressure mechanism 3 includes a bearing seat 31 fixedly connected to the inner side of the cover plate 1, and a rotating shaft 32 is rotatably connected to the bearing seat 31. Connecting rods 34 are fixedly provided at both ends of the rotating shaft 32. The connecting rod 34 is fixedly provided with a pressure rod 35 for pressing the filter screens 5 of different widths. When the filter screen 5 is installed, the rotation of the rotating shaft 32 can drive the pressure rod 35 to rotate through the connecting rod 34, so that the pressure rod 35 is tightly pressed against the two ends of the filter screen 5 to achieve the purpose of reducing the gap.

[0025] To install and fix the filter 5, please refer to Figure 3 The fixing mechanism 2 includes a fixing block 21 fixedly connected to the inner side of the cover plate 1, a U-shaped rod 22 is fixedly provided on the fixing block 21, a spring 23 and a movable clamping block 24 are sleeved on the U-shaped rod 22, the spring 23 is located on the side of the movable clamping block 24 away from the fixing block 21, and the movable clamping block 24 is provided with a bayonet that is engaged with the fixing rod 4. When installing the filter 5, the movable clamping block 24 is first pushed to move, at which time the spring 23 is in a compressed state, and then the fixing rod 4 is placed on the movable clamping block 24. After the movable clamping block 24 is released, the spring 23 pushes the movable clamping block 24 to reset, and at this time the fixing rod 4 is clamped into the bayonet, thereby forming a fixed state.

[0026] In order to facilitate automatic pressing of the two ends of the filter screen 5, teeth 25 are provided on the movable block 24 and mesh with two gears 33 through the teeth 25. The two gears 33 are respectively fixed to the two ends of the rotating shaft 32. When the movable block 24 is pushed, the gears 33 can be driven to rotate under the action of the teeth 25, so that the pressure rod 35 can be rotated and opened to install the filter screen 5. When the filter screen 5 is installed, the movable block 24 is released, and the movable block 24 is reset to move so that the pressure rod 35 can be rotated, thereby pressing the two ends of the filter screen 5.

[0027] To facilitate pressing down the filter screens 5 of different widths, the pressure rod member 35 includes a fixed pressure rod 351 fixedly connected to one end of the two connecting rods 34, and movable pressure rods 352 are sleeved at both ends of the fixed pressure rod 351. Adjustment screws 353 are also threadedly connected at both ends of the fixed pressure rod 351. After loosening the adjustment screws 353, the length of the movable pressure rod 352 can be extended to adapt to filter screens 5 of different widths.

[0028] To ensure that the pressing rod 35 can completely press the two ends of the filter screen 5, the length of the pressing rod 35 is made the same as the width of the filter screen 5, so that the gaps at the two ends of the filter screen 5 will be smaller, so that the filter screen 5 can filter the medium better.

[0029] To ensure that the medium can pass through the filter screen 5 smoothly, the filter screen 5 is attached to the inner side of the opening 11 . When the medium passes through the opening 11 , it can be directly filtered through the filter screen 5 .

[0030] It can be known from the above embodiment that when installing the filter 5, the movable block 24 is first pushed to move, at which time the spring 23 is in a compressed state, and then the fixed rod 4 is placed on the movable block 24. After the movable block 24 is released, the spring 23 pushes the movable block 24 to reset, and at this time the fixed rod 4 is stuck in the bayonet, thereby fixing the filter 5. When the movable block 24 is pushed, the gear 33 can be driven to rotate under the action of the teeth 25, and the pressure rod 35 can be rotated and opened under the action of the rotating shaft 32 and the connecting rod 34, so as to install the filter 5. When the filter 5 is installed, the movable block 24 is reset to move, which can make the pressure rod 35 rotate, thereby pressing on the two ends of the filter 5 to reduce the gap between the filter 5 and the opening 11.
