[0027] Among them, the adjustment component includes two gears 406 fixed on the front and rear sides of the outer surface of the rotating rod 405, and a tooth plate 408 is meshed on the upper part of the outer surface of the gear 406.

[0030] It should be noted that the start component drives the adjustment component to move, and cooperates with the fixing component, so that the upper tank body 2 and the lower tank body 3 can be easily disassembled, assembled and fixed, and the fiber filter paper 506 can be replaced in cooperation with the filter mechanism 5.

[0031] The working principle of the above embodiment is:

[0032] (1) When the fiber filter paper 506 needs to be replaced, the handle 403 is first rotated to drive the worm 402 and the worm wheel 404 to rotate, thereby causing the rotating rod 405 to rotate, and then the rotating rod 405 drives the two gears 406 to rotate, so that the two tooth plates 408 can move along the two connecting rods 407, and then the limiting rod 409 can be driven to move along the connecting hole 410 until the limiting rod 409 is no longer in contact with the inner wall of the limiting groove 411, and then the limiting rod 409 can be completely moved out of the limiting groove 411 by moving the lower tank body 3 downward, and at this time, the upper tank body 2 and the lower tank body 3 are no longer in contact and fixed.

[0033] (2) After the upper tank body 2 and the lower tank body 3 are separated conveniently, the annular thread block 504 is driven to rotate along the annular thread groove 503 by rotating the second filter screen 505, so that the annular thread block 504 is disengaged from the annular thread groove 503. At this time, the second filter screen 505 no longer fixes the fiber filter paper 506, and the fiber filter paper 506 can be removed and replaced. The annular thread block 504 is fixedly connected to the annular thread groove 503 to fix the second filter screen 505. Then, the lower tank body 3 and the upper tank body 2 are fixed according to the above principle to complete the replacement of the fiber filter paper 506. It can be seen from the above steps that when the staff needs to replace the fiber filter paper 506, they do not need to use other tools to disassemble the fixing bolts, which saves time and effort, improves their own work efficiency, and can also further avoid the loss of bolt parts after disassembly.
