At the same time, the shape of the water hole 130 forms a conical structure, so that the water pressure of the water entering the water hole 130 is further increased, thus ensuring the water pressure when the water hole 130 discharges water.

[0024] The first side 121 is close to the first opening 111, and the second side 122 is close to the second opening 112. An insertion port 140 communicating with the outside of the chamber 110 is provided on the first side 121, and a socket 150 corresponding to the position of the insertion port 140 is provided on the second side 122. The filter net 400 passes through the insertion port 140 and is inserted into the socket 150. A baffle 500 for blocking the insertion port 140 is installed on the body 100. The baffle 500 is provided with a limit projection 510 embedded in the insertion port 140, and the baffle 500 and the body 100 are fixed by a fastener 520. After the filter net 400 is inserted into the chamber 110, the limit projection 510 on the retaining ring is inserted into the insertion port 140 to make the limit projection 510 abut against the filter net 400, thereby blocking the filter net 400 and the insertion port 140.
