Specifically, the filter screen 3 is an arc-shaped regular plate-shaped structure, the left and right edge portions of the filter screen are respectively provided with an unlimited number of the connecting structures, each connecting structure is paired with an installation portion 14 arranged on the edge of the filter screen, and the first buckle 11 and the second buckle 12 are both installed on the installation portion 14.

As shown in fig. 3, the mounting portion 14 includes an opening 131, a mouth end of the opening 131 faces the housing 2, a pair of extension plates 132 at two sides of the mouth end, the first buckle 11 and the second buckle 12 are both mounted on the extension plates 132, wherein the first buckle 11 and the second buckle 12 are rotatably connected with the filter screen, a first rotating shaft 133 and a second rotating shaft 134 are disposed between the two extension plates on the pair of extension plates 132, and the first rotating shaft 133 and the second rotating shaft 134 are disposed in parallel.

As shown in fig. 4 and 5, the first buckle 11 is installed on the first rotating shaft 133, the second buckle 12 is installed on the second rotating shaft 134, the left end of the first buckle 11 is a first clamping end 111 that abuts against the housing, and the housing 2 is provided with a clamping portion 21 that is opposite to the opening and is clamped with the first buckle; the right end of the first buckle 11 is a second clamping end 112 abutting against the second buckle 12, and the first clamping end 111 and the second clamping end 112 are respectively disposed at two sides of the first rotating shaft 133.

The driving device in one embodiment may be a pair of mutually exclusive magnets, which includes a first magnet disposed on the clamping portion 21 of the housing 2 and a second magnet disposed on the first clamping end 111, the first magnet and the second magnet have opposite magnetism to drive the first buckle 11 to rotate around the first rotating shaft 133, and the first clamping end 111 moves towards a direction away from the housing 2 and has a butting effect on the filter screen and the housing.

As shown in fig. 6, the driving device may also be an elastic expansion member, such as a torsion spring or a spring plate; in another embodiment, the elastic expansion member is a torsion spring 13, a blocking body 135 is disposed between the pair of extension plates 132, the blocking body 135 is located below the first buckle 11, the torsion spring is sleeved on the first rotating shaft 133, two elastic arms of the torsion spring are located on the right side of the first rotating shaft 133, namely, located on one side of the second buckle end 112, one of the elastic arms abuts against the first buckle, the other elastic arm abuts against the blocking body, so that the torsion spring can abut against the second buckle end 112 to rotate, and at this time, the first buckle end 111 moves towards a direction away from the housing 2 to perform a buckling action on the filter screen and the housing.

The second buckle 12 includes a body 121, the body 121 is a pressing portion for an operator to press, wherein the body 121 is located on one side of the second rotating shaft 134, the pressing of the body 121 causes the second buckle to rotate around the second rotating shaft 134, the left end of the body 121 is a third buckling end 122 abutting against the first buckle, a contact portion (a stress point) of the third buckling end 122 and the first buckle 11 is located on one side of the body 121 of the second rotating shaft 134 or passes through the rotating shaft under stress, so that the moment of the third buckling end 122 relative to the second rotating shaft 134 is 0, the second buckle can abut against the first buckle, the second buckle cannot rotate synchronously under stress when the first buckle rotates, the situation that the second buckle 12 cannot abut against the first buckle 11 is avoided, and a buckle effect is ensured.

Further, the right end of the main body 121 is a fourth clamping end 123, the fourth clamping end 123 is far away from the second rotating shaft 134, the fourth clamping end 123 abuts against the inner side of the filter screen, the third clamping end 122 is acted by the first buckle, and the third clamping end 122 is located on one side of the second rotating shaft 134 with the main body 121, therefore, when the second buckle 12 is pushed by the first buckle, the second buckle cannot rotate out of the filter screen, the second buckle always abuts against the first buckle, the clamping effect between the first buckle and the shell is guaranteed, and the filter screen and the shell are well assembled.

Further, for making the second buckle remain stable, also can set up the magnet or the elastic construction that attract each other between fourth joint end 123 and casing so that the second buckle can keep with the casing between the laminating you together, guarantee the effect of buckle.

Further, the width of the main body 121 should be designed to be about the width of a finger, so that not only is pressing prevented from being affected, but also the air supply area is prevented from being affected due to an excessively large buckle area; simultaneously, the appearance surface of the buckle structure is matched with the appearance of the filter screen, so that the buckle is prevented from being interfered by the outside and the appearance is ensured to be attractive.

Preferably, the utility model provides a buckle and pivot can adopt metalwork or injection molding, but because of its volume is less, so require to teach high to intensity and stability, and ordinary injection molding intensity and stability are relatively poor, consequently preferred metalwork.

The connection structure enables the filter screen and the shell to be easily disassembled and stably installed, when the filter screen needs to be disassembled, the second buckle 12 is pressed, the second buckle 12 moves towards the inner side of the shell under the action of external force, the second buckle loses the binding effect on the second clamping end 112 of the first buckle 11, the first buckle 11 overturns downwards under the action of the driving device, the first clamping end 111 of the first buckle 11 is separated from the shell, and the filter screen is disassembled; when the filter screen is installed, the filter screen is buckled, the first buckle 11 is firstly pressed down, and the second buckle 12 is pushed to be abutted against the first buckle 11, so that the installation is completed. Through pressing down second buckle 12 alright accomplish the dismouting of filter screen, second buckle 12 provides the constraint effect to first buckle simultaneously, and both can not break away from automatically through the outside application of force, and first buckle can be in the same place with the card that the casing is tight to the assembly effect of filter screen and casing has been guaranteed.
