The working principle of the invention is as follows:
1. Automatic draining
When the driving piece 423 is started to work, the lifting rod 410 can be driven to act, so that the lifting rod 410 takes a rotating shaft in the valve body 200 as a fulcrum to drive the valve core to lift, and the valve core drives the water stopping piece to lift, so that the water draining valve can realize flushing action.
At the same time as the lifting lever 410 moves, the lifting lever 410 drives the driving arm 5342, so that the rotating arm 5341 drives the crank arm 533, and further drives the crank arm 533 and the back pressure pad 524 on the crank arm 533 to move, so that the back pressure pad 524 is separated from the first pressure relief hole 5211, the first pressure relief hole 5211 is opened, and water is pumped to the anti-siphon component 620 by the water inlet pressure of the direct water to flow to the brush ring spray head 630.
When the driving piece 423 stops working, the lifting rod 410 is driven to reset, and when the water level is not lowered to the action position set by the pontoon 720, the pontoon 720 still connects the limiting part 731 with the hook 311 of the valve core under the action of the buoyancy force, so as to keep the flushing action of the drain valve. When the water level drops to the action position set by the pontoon 720, the pontoon 720 drives the swing arm 730 to rotate under the action of gravity, so that the limiting part 731 is unhooked from the hook 311, after the swing arm 730 is unhooked, the valve core and the water stopping member are reset under the action of gravity and the valve core resetting member, the water outlet is closed, and the water draining valve stops the flushing action.
At the same time of resetting the lifting lever 410, the crank arm 533 is reset under the action of the crank arm resetting piece 535, and the crank arm 533 and the back pressure pad 524 move, so that the back pressure pad 524 closes the first pressure relief hole 5211, and the brush ring sprayer 630 stops water discharge.
2. Manual drainage
After the manual controller 427 is operated, it drives the lifting rod 410 to act, so that the lifting rod 410 drives the valve core to lift by taking the rotating shaft in the valve body 200 as a fulcrum, and the valve core drives the water stop to lift, so that the water discharge valve realizes the flushing action.
At the same time as the lifting lever 410 moves, the lifting lever 410 drives the driving arm 5342, so that the rotating arm 5341 drives the crank arm 533, and further drives the crank arm 533 and the back pressure pad 524 on the crank arm 533 to move, so that the back pressure pad 524 is separated from the first pressure relief hole 5211, the first pressure relief hole 5211 is opened, and water is pumped to the anti-siphon component 620 by the water inlet pressure of the direct water to flow to the brush ring spray head 630.
After the manual controller 427 stops working on the connecting piece, when the water level does not drop to the action position set by the pontoon 720, the pontoon 720 still connects the limiting part 731 with the hook 311 of the valve core under the action of the buoyancy so as to keep the flushing action of the drain valve. When the water level drops to the action position set by the pontoon 720, the pontoon 720 drives the swing arm 730 to rotate under the action of gravity, so that the limiting part 731 is unhooked from the hook 311, after the swing arm 730 is unhooked, the valve core and the water stopping member are reset under the action of gravity and the valve core resetting member, the water outlet is closed, and the water draining valve stops the flushing action.
At the same time of resetting the lifting lever 410, the crank arm 533 is reset under the action of the crank arm resetting piece 535, and the crank arm 533 and the back pressure pad 524 move, so that the back pressure pad 524 closes the first pressure relief hole 5211, and the brush ring sprayer 630 stops water discharge.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
