[0039] When the staff needs to clean the dirt on the louver 701, the staff rotates the buckle 705 to disengage the buckle 705 from the retaining ring 706. Then, the staff rotates the louver 701 to open it, making it easy to clean the dirt on the louver 701. After the dirt is cleaned, the staff reverses the louver 701 to reset it and contact the outer shell 1. Then, the staff reverses the buckle 705 to lock the buckle 705 into place with the retaining ring 706, which can close the louver 701.

[0043] With the water level in the water storage pool 3 rising to a certain height, the floating plate 902 moves upward between the four guide blocks 901, driving the sliding block 904 to move forward, the sliding block 904 contacts the extrusion disc 905, at the same time, the rotating pipe 403 rotates to drive the extrusion disc 905 to rotate, so that the sliding block 904 moves upward again along the recess at the edge of the extrusion disc 905, driving the blocking piece 903 to slide upward, so that the two water outlets 907 are opened, the water in the water storage pool 3 flows into the water release frame 908 through the two water outlets 907, and then is discharged through the drain pipe 909, so as to play a role of releasing water. Because the smooth edge of the extrusion disc 905 is long, the sliding block 904 will not fall down in a short period of time, so that the water in the water storage pool 3 can be completely discharged, when the sliding block 904 is in the recess at the edge of the extrusion disc 905, the water in the water storage pool 3 has been completely discharged, then the extrusion disc 905 extrudes the sliding block 904, driving the sliding block 904 to move downward, driving the blocking piece 903 to slide downward, so that the floating plate 902 moves downward, driving the sliding block 904 to move downward, at the same time, the blocking piece 903 moves downward to reset, so as to close the two water outlets 907 and stop the water discharge.

[0044] The abrasive particles at the hand holding part of the handle 606 can increase the friction between the hands of the staff and the handle 606, and can play a good anti-skid effect.
