[0020] 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.

[0021] See also Figure 1-Figure 3 A filter screen connection structure with tension adjustment includes an air filter 1. A mounting groove is provided on the top of the air filter 1. A group of guide grooves are provided through the front and rear sides of the mounting groove. A tensioning component is placed in the mounting groove, and a fixing component is placed in the guide groove.

[0022] The tensioning assembly includes a connecting frame 32, an extrusion frame 34 is placed on the right side of the connecting frame 32, and springs 33 are evenly fixed between the connecting frame 32 and the extrusion frame 34. The top right side of the extrusion frame 34 is designed as an arc, and the support frame 2 can be easily plugged in and out through the holding groove 21. Benefiting from the arc design on the top right side of the extrusion frame 34, the support frame 2 can be more easily inserted into the gap between the extrusion frame 34 and the installation groove.

[0023] A support frame 2 is inserted into the mounting groove, a filter screen 22 is fixedly provided on the inner wall of the support frame 2, a holding groove 21 is opened on the top right side of the support frame 2, a sealing gasket 23 is fixedly provided on the right side of the support frame 2, the right side of the sealing gasket 23 is fitted with the right side of the inner wall of the mounting groove, and the right side of the extrusion frame 34 is fitted with the left side of the support frame 2. The extrusion frame 34 can be squeezed to the right by the tensioning force of the spring 33, so that the sealing gasket 23 is tightly fitted with the right side of the inner wall of the mounting groove, thereby ensuring that the flowing air can be fully filtered by the filter screen 22.

[0024] The fixing assembly includes blocks 311 , and two groups of blocks 311 are fixedly arranged on the front and rear sides of the connection frame 32 , respectively. A group of screw rods 3 are fixedly arranged on the opposite sides of the two groups of blocks 311 , and nuts 31 are screwed on the outer side walls of the screw rods 3 .

[0025] The block 311 is slidably set in the guide groove, and the opposite sides of the two sets of nuts 31 are respectively fitted with the front and rear sides of the air filter 1. The connecting frame 32 can rely on the block 311 to move left and right, and then drive the extrusion frame 34 to move synchronously, so as to change the tensioning force applied to the support frame 2 by the spring 33 through the extrusion frame 34, so that support frames 2 of different thicknesses can be inserted into the installation groove. By changing the thickness and type of the support frame 2 and the filter 22, the air filter 1 can meet the air filtration needs of different requirements. After tightening the nut 31, the fixing of the connecting frame 32 can be completed.

[0026] A magnetic plate 11 is fixedly arranged at the bottom of the mounting groove, and an iron plate 24 is inlaid at the bottom of the support frame 2. The magnetic plate 11 and the iron plate 24 are adsorbed on each other. Through the mutual adsorption of the magnetic plate 11 and the iron plate 24, and the pressure exerted on the support frame 2 by the extrusion frame 34, the support frame 2 can be stably fixed in the air filter 1. When the support frame 2 needs to be replaced, it only needs to be directly unplugged and plugged, thereby improving the convenience of use of the device.

[0027] Working principle: The support frame 2 can be easily plugged in and out and assembled and disassembled through the gripping groove 21. Thanks to the arc design on the top right side of the extrusion frame 34, the support frame 2 can be more easily inserted into the gap between the extrusion frame 34 and the mounting groove. The tensioning force of the spring 33 can make the extrusion frame 34 squeeze the support frame 2 to the right, so that the sealing gasket 23 fits tightly with the right side of the inner wall of the mounting groove, thereby ensuring that the flowing air can be fully filtered by the filter screen 22. The connecting frame 32 can move left and right by relying on the block 311, thereby driving the extrusion frame 34 to move synchronously, thereby changing the spring 33. The tensioning force applied to the support frame 2 by the extrusion frame 34 can make it possible to insert support frames 2 of different thicknesses into the installation groove. By changing the thickness and type of the support frame 2 and the filter 22, the air filter 1 can meet the air filtration needs of different requirements. After tightening the nut 31, the connection frame 32 can be fixed. Through the mutual adsorption of the magnetic plate 11 and the iron plate 24, and the pressure applied to the support frame 2 by the extrusion frame 34, the support frame 2 can be stably fixed in the air filter 1. When the support frame 2 needs to be replaced, it only needs to be directly unplugged and plugged, thereby improving the convenience of use of the device.
