[0013] Furthermore, a second rubber sheet is provided on the side wall of the limiting plate away from the threaded rod.

[0014] By adopting the above technical solution, when the connection frame is initially kept stable, the staff only needs to rotate the threaded rod to make the two second rubber sheets respectively press against the two opposite side walls of the connection frame under the action of the threaded rod. At this time, the two first rubber sheets respectively press against the other two side walls of the connection frame, thereby making the two first rubber sheets cooperate with the two second rubber sheets and improving the stability of the connection frame, thereby reducing the probability of water flowing directly over the connection frame.

[0015] Furthermore, an annular plate for blocking the connection frame is provided on the inner wall of the tank body.

[0016] By adopting the above technical solution, when the staff needs to install the filter, the staff needs to put the filter into the tank body, so that the annular plate can support the connecting frame, thereby keeping the connecting frame stable.
