[0026] Furthermore, the filter element body 2 is a prior art and is not the main innovation of the main application, and its purification principle and specific structure are not described in detail here.

[0027] The working principle of the utility model is as follows: by taking out the filter element body 2 that needs to be replaced, holding the buckle groove 508 with a finger and pulling the paddle 505, the paddle 505 drives the clamping block 504 to disengage from the fixing groove 502, so that the fixing rod 501 is released from the restriction, and the first clamping edge 1 and the second clamping edge 3 can be separated, so that the replacement of the filter element body 2 is convenient, and there is no need to replace the entire body, reducing the replacement cost and avoiding resource waste. When installing, the filter element body 2 is clamped between the first clamping edge 1 and the second clamping edge 3, so that the fixing rod 501 Insert the block 504 into the slot through the hole on the filter element body 2, and then insert the block 504 into the fixed groove 502. The operation is simple and does not require the aid of tools to assist in installation. When the first clamping edge 1 and the second clamping edge 3 are separated, the paddle 505 is pushed to make the rectangular block 9 pass through the rectangular hole 6 into the buckle groove 508, and then the rectangular block 9 is rotated to form a cross with the rectangular hole 6, thereby preventing the block 504 from resetting, making it convenient for the user to free up his hands to release the four fixing parts on the first clamping edge 1 in turn, thereby providing convenience for the disassembly and assembly of the filter element body 2.
