At this time, the first base positioned in the first accommodating cavity does not displace, and the water valve connected to the first base through the first rotating shaft does not displace transversely at this time. When the first sliding block slides towards the first spring, the first control unit positioned in the first groove of the first sliding block slides towards the third rotating shaft, the pawl originally embedded between the ratchet structures of the outer side wall of the third rotating shaft at one end can push the ratchet structures to displace towards the direction of the first spring, and at the moment, the third rotating shaft can circumferentially rotate on the first base. At this time, the second arc-shaped guide surface is attached to the first arc-shaped guide surface. When the third rotating shaft rotates circumferentially, the columnar protrusions on the upper end face of the third rotating shaft rotate circumferentially along with the third rotating shaft, and at the moment, the first gaps between the two columnar protrusions are communicated with the water outlet. When water enters the first accommodating cavity from the water inlet of the outer side wall of the shell, the water enters the water outlet from the first gap. At this time, the user releases the button that presses, and the first sliding block can slide to deviating from the direction of the third pivot under the pushing of the first spring. The second arc-shaped guide surface of the pusher dog can slide towards the second groove direction between each ratchet structure along the first guide cambered surface of the outer side wall of each ratchet structure until the end part of the pusher dog far away from one end of the columnar rotating block is embedded into the second groove. Because the second spring is arranged between the left side of the second limiting protrusion and the left side inner side wall of the first groove, when the pusher dog slides to the second groove, the second spring can push the second limiting protrusion to slide to the right side of the columnar rotating block, and the opposite pusher dog can rotate in the opposite direction along with the rotation of the second limiting protrusion, namely, the pusher dog can be tightly embedded into the second groove at the moment.

When the water valve needs to be closed, and water cannot enter the filter element. The user only needs to press the button on the outer side wall of the shell again, the button can push the first sliding block to slide in the first accommodating cavity towards the direction of the first spring, and the first spring is extruded. At this time, the first base positioned in the first accommodating cavity does not displace, and the water valve connected to the first base through the first rotating shaft does not displace transversely at this time. When the first sliding block slides towards the first spring, the first control unit positioned in the first groove of the first sliding block slides towards the third rotating shaft, the pawl originally embedded between the ratchet structures of the outer side wall of the third rotating shaft at one end can push the ratchet structures to displace towards the direction of the first spring, and at the moment, the third rotating shaft can circumferentially rotate on the first base. At this time, the second arc-shaped guide surface is attached to the first arc-shaped guide surface. When the third rotating shaft rotates circumferentially, the columnar bulge on the upper end face of the third rotating shaft rotates circumferentially along with the third rotating shaft, the columnar bulge rotates to the position where the first gap is located, the water outlet abuts against the outer side wall of the columnar bulge, and the columnar bulge closes the water outlet. When water enters the first accommodating cavity from the water inlet of the outer side wall of the shell, the water enters the water outlet from the first gap. At this time, the user releases the button that presses, and the first sliding block can slide to deviating from the direction of the third pivot under the pushing of the first spring. The second arc-shaped guide surface of the pusher dog can slide towards the second groove direction between each ratchet structure along the first guide cambered surface of the outer side wall of each ratchet structure until the end part of the pusher dog far away from one end of the columnar rotating block is embedded into the second groove. Because the second spring is arranged between the left side of the second limiting protrusion and the left side inner side wall of the first groove, when the pusher dog slides to the second groove, the second spring can push the second limiting protrusion to slide to the right side of the columnar rotating block, and the opposite pusher dog can rotate in the opposite direction along with the rotation of the second limiting protrusion, namely, the pusher dog can be tightly embedded into the second groove at the moment.
