When needs are washed by water, the flap cover body is driven (pulled) by the driving motor on the intelligent driving device, so that the flap cover body rotates and opens relative to the flap cover base, water in the closestool is flushed out from the water outlet to the closestool flushing port to flush water, the flap cover body is released by the intelligent driving device after the flushing is finished, and the flap cover body covers the water outlet tightly under the pressing action of gravity and the elastic pressing piece.
According to the flap cover type drain valve, the height of the connecting column is higher than that of the water outlet, the water outlet is inclined towards the direction opposite to the connecting column, and when the flap cover body covers the flap cover base, the flap cover body is also inclined downwards relative to the connecting column, so that the sealing performance of the flap cover body covering the water outlet is improved.
According to the flap type drain valve, the convex column is arranged on one side of the flap base, the elastic pressing piece is the torsion spring sleeved on the connecting column, one end of the elastic pressing piece is sleeved on the convex column, the other end of the elastic pressing piece is pressed on the connecting rod or the cover plate in a propping mode, the torsion spring always applies downward acting force to the connecting rod or the cover plate, and therefore the fastening performance of the flap body for covering the drain outlet is guaranteed.
According to the flap type drain valve, the drain outlet is provided with the sealing convex ring along the circumferential outer side, and the cover plate is provided with the sealing rubber ring which is in sealing fit with the sealing convex ring, so that the sealing performance of the flap body for covering the drain outlet is further improved.
According to the flap type drain valve, the cover plate is provided with the counterweight convex block which can be sleeved in the drain port and is used for the sealing rubber ring to be sleeved in, the counterweight convex block can increase the overall gravity of the cover plate, and the sealing performance of the flap body for covering the drain port is further improved.
[ description of the drawings ]
The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
fig. 1 is a schematic exploded view of the present invention;
FIG. 2 is a schematic view of the three-dimensional structure of the present invention when covered;
fig. 3 is a schematic view of the cross-sectional structure of the present invention when covering.
[ detailed description ] embodiments
A flap type drain valve comprises a flap base 1 provided with a drain port 11 and a flap body 2 rotatably arranged on the flap base 1 to open or close the drain port 11, wherein an elastic pressing piece 3 capable of tightly closing the flap body 2 to the drain port 11 is arranged between the flap body 2 and the flap base 1.
The racket cover body 2 comprises a cover plate 21 for covering the water outlet 11 and a connecting rod 22 arranged on the side of the cover plate 21 and used for being rotatably connected with the racket cover base 1, and one side of the racket cover base 1 is provided with a connecting column 12 for being rotatably connected with the end of the connecting rod 22. In order to ensure the stress balance, the two sides of the cover plate 21 are both provided with connecting rods 22, and correspondingly, the racket cover base 1 is provided with connecting columns 12 for rotatably connecting the two connecting rods 22.
The height of the connecting column 12 is higher than that of the drain port 11, and the drain port 11 is inclined in a direction opposite to the connecting column 12. When the racket cover body 2 is covered on the racket cover base 1, the racket cover body 2 is also inclined downwards relative to the connecting column 12, thereby improving the sealing performance of the racket cover body 2 covering the water outlet 11.
One side of the racket cover base 1 is provided with a convex column 13, the elastic pressing piece 3 is a torsion spring sleeved on the connecting column 12, one end of the elastic pressing piece is sleeved on the convex column 13, and the other end of the elastic pressing piece is pressed on the connecting rod 22 or the cover plate 21. In order to improve the elastic pressing effect, the torsion springs can be respectively arranged on the two connecting columns 12.
In order to further improve the sealing performance of the flap body 2 for covering the water outlet 11, a sealing convex ring 111 is arranged along the circumferential outer side of the water outlet 11, and a sealing rubber ring 211 which is in sealing fit with the sealing convex ring 111 is arranged on the cover plate 21. The cover plate 21 is provided with a counterweight protrusion 212 which can be sleeved in the water outlet 11 and is used for a sealing rubber ring 211 to be sleeved.
When the utility model is used and needs to be flushed, the driving motor on the intelligent driving device drives (pulls) the flap cover body 2 to rotate and open (the output end of the driving motor is provided with a pull wire for pulling the flap cover body 2), so that water in the toilet is flushed out from the water outlet 11 to the toilet flushing port to realize flushing, after flushing is finished, the intelligent driving device releases the flap cover body 2, at the moment, the flap cover body 2 tightly covers the water outlet 11 again under the pressing action of gravity and the elastic pressing piece to complete flushing of the toilet, at the moment, the elastic pressing piece 3 tightly presses the flap cover body 2 on the flap cover base 1 and tightly covers the water outlet 11, thereby preventing the dirty water in the pipeline from backflushing and flowing backwards and jacking the flap cover body 2 to flow back to the toilet water tank, thereby effectively preventing the back flow of excrement and dirty water, polluting a water tank of the closestool and generating odor.
