It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 6 As shown, the utility model provides a detachable particle interception filter, a slot 6 is provided at the top of the inner surface of the pipe 3, a support frame 2 is inserted into the inner surface of the slot 6, a placement slot 8 is provided on the front surface of the support frame 2, a filter body 4 is provided on the inner surface of the placement slot 8, a sliding slot 16 is provided on the inner wall of one side of the slot 6, a rectangular block 12 is fixedly connected to the inner bottom of the sliding slot 16, a threaded rod 14 is fixedly passed through the right surface of the rectangular block 12 through a bearing, the outer surface of the threaded rod 14 is threadedly connected to the limiting block 7, a card slot 5 is provided on the outer surface of the support frame 2 near the top, the inner surface of the card slot 5 is connected to the outer surface of the limiting block 7 The surface is arranged in a snap-fitting manner, the inner surface of the sliding groove 16 and the outer surface of the limit block 7 are arranged in a sliding manner, the first bevel gear 11 is fixed to the left end face of the threaded rod 14, the top of the pipeline 3 movably penetrates the rotating rod 1 and extends to the inside of the sliding groove 16, the outer surface of the rotating rod 1 is fixedly connected to the second bevel gear 15 near the center position, the outer surface of the first bevel gear 11 is meshed with the outer surface of the second bevel gear 15, the bottom of the rotating rod 1 is rotatably connected to the inner bottom of the sliding groove 16, the outer surface of the filter body 4 cooperates with the inner surface of the placement groove 8, and the outer surface of the support frame 2 is fixedly connected to the sealing gasket 10 at the top position.

[0025] The effect achieved by the entire embodiment 1 is that when the filter body 4 needs to be disassembled and cleaned, the handle on the rotating rod 1 is turned to drive the rotating rod 1 to rotate in the pipe 3 and the sliding groove 16, so that the second bevel gear 15 is driven to rotate by the rotation of the rotating rod 1, and the meshing arrangement of the second bevel gear 15 and the first bevel gear 11 will drive the first bevel gear 11 to rotate, thereby driving the threaded rod 14 to rotate on the rectangular block 12, so that the limit block 7 moves to the left along the threaded rod 14 and the sliding groove 16, so that the limit block 7 and the card slot 5 are no longer engaged, and then the support frame 2 is moved outward along the slot 6 through the handle groove on the support frame 2, so that the support frame 2 and the pipe are 3, then pull out the filter body 4 from the placement slot 8, clean and maintain it. When the cleaning is completed, insert the filter body 4 into the support frame 2 along the placement slot 8, and then insert the support frame 2 into the pipe 3 along the slot 6. After the insertion is completed, rotate the rotating rod 1 in the opposite direction to rotate the threaded rod 14, so that the limiting block 7 presses the sliding slot 16 to move to the right and engages with the card slot 5 to complete the limiting fixation of the support frame 2, so that the filter body 4 can be quickly installed. At the same time, after the installation is completed, with the cooperation of the sealing gasket 10, the support frame 2 and the pipe 3 are squeezed and deformed to fill the gap at the connection, thereby ensuring the sealing after installation.

[0026] Embodiment 2, as Figure 1-Figure 6 As shown, the left surface of the rectangular block 12 movably passes through the limiting rod 13 , and the right end surface of the limiting rod 13 is fixedly connected to the left surface of the limiting block 7 .

[0027] The effect achieved by the entire embodiment 2 is that when the limit block 7 moves, it will drive the limit rod 13 to move synchronously along the rectangular block 12, so that the movement stroke of the limit block 7 can be limited by the cooperation of the limit rod 13 and the rectangular block 12, thereby avoiding the limit block 7 and the threaded rod 14 from being separated.

[0028] Working principle: when the filter body 4 needs to be disassembled and cleaned, the handle on the rotating rod 1 is turned to drive the rotating rod 1 to rotate in the pipe 3 and the sliding groove 16, so that the second bevel gear 15 is driven to rotate by the rotation of the rotating rod 1, and the meshing arrangement of the second bevel gear 15 and the first bevel gear 11 will drive the first bevel gear 11 to rotate, thereby driving the threaded rod 14 to rotate on the rectangular block 12, so that the limit block 7 moves to the left along the threaded rod 14 and the sliding groove 16. During the movement, the limit block 7 can be limited by the limit rod 13, so that the limit block 7 is no longer engaged with the slot 5, and then the support frame 2 is moved outward along the slot 6 through the handle groove on the support frame 2, so that the support frame 2 The support frame 2 is thus detached from the pipe 3, and then the filter body 4 is pulled out from the placement groove 8 for cleaning and maintenance. When the cleaning is completed, the filter body 4 is inserted into the support frame 2 along the placement groove 8, and then the support frame 2 is inserted into the pipe 3 along the slot 6. After the insertion is completed, the rotating rod 1 is rotated in the opposite direction to rotate the threaded rod 14, so that the limit block 7 presses the sliding groove 16 to move to the right and engages with the card slot 5 to complete the limit fixation of the support frame 2, so that the filter body 4 can be quickly installed. At the same time, after the installation is completed, with the cooperation of the sealing gasket 10, the support frame 2 and the pipe 3 are squeezed and deformed to fill the gap at the connection, thereby ensuring the sealing after installation. The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
