The pulling string 42 can be a chain or a rope, and the flap cover 20 is provided with a hole near the front side for fixing the pulling string 42.
In the present invention, the weight mechanism 60 is provided with a rotating rod 61 and a weight block 62, the rotating rod 61 is rotatably disposed on the racket cover 20, and the weight block 62 is mounted on one end of the rotating rod 61. The racket cover 20 may have at least one engaging groove 23 on the top surface, the rotating rod 61 may be engaged into the engaging groove 23 to achieve rotatable connection, and the other end of the rotating rod 61 may have a roller to play a guiding role, so that the rotating rod 61 rotates more smoothly and stably.

Specifically, a first limit block 64 and a second limit block 65 may be disposed on two sides of the rotating rod 61, the first limit block 64 abuts against the racket cover 20 to limit the weight mechanism 60 in the front direction, and the second limit block 65 abuts against the racket cover 20 to limit the weight mechanism 60 in the rear direction. Or the flap cover 20 can be provided with a first protrusion and a second protrusion which are respectively positioned at the front side and the rear side of the end of the rotating rod 61 where the connecting rod 63 is positioned, so that the front and rear limiting can be realized.
In the present invention, referring to fig. 4, when the weight mechanism 60 is in the front limit position in the state where the flap 20 is closed on the base 10, the rotating rod 61 cannot rotate forward, and this state is a stable normal state. Referring to fig. 3, when the counterweight mechanism 60 is in the rear limit position, since the rotating rod 61 is slightly inclined forward with respect to the horizontal plane in this state, this state cannot be maintained, and the rotating rod 61 rotates forward by gravity, and finally becomes the front limit position.

If configured to rotate, its axis of rotation may be connected to the bracket 53 or the overflow tube 30, which may be near the end of the stop 70 that is connected to or in contact with the top shift knob 51. If the stopper 70 is provided to be slidable with respect to the overflow pipe 30, an elastic return member is further connected to the stopper 70, and one end of the elastic return member is fixed and the other end abuts against the stopper 70. Specifically, the bottom of the large-gear button 51 may be provided with a push rod 56, one end of the stopper 70 is provided with a first transmission portion 71, the first transmission portion 71 is in abutting contact with the push rod 56, and the other end of the stopper 70 is provided with a stopping surface 72, and the area of the stopping surface 72 may be slightly larger than the cross-sectional area of other parts of the stopper 70. In order to limit the rotation angle of the stopper 70, a limit groove 74 may be provided on the rotation shaft or the bracket 53 or the overflow pipe 30, the stopper 70 is correspondingly provided with a projection 73, the projection 73 is located in the limit groove 74, and the projection 73 can slide in the limit groove 74 when the stopper 70 rotates.
In a normal state, the first transmission part 71 of the stopper 70 is tilted, when the top key 51 is pressed, the bottom thereof presses down the second transmission part 43 of the transmission rod 41, the push rod 56 presses down the first transmission part 71 of the stopper 70, and the stopper surface 72 is lifted. The invention also provides a flap type water tank device which comprises a water tank, a water inlet valve and the double-gear flap type drain valve, wherein after the large-gear key 51 is pressed to be loosened, when the water level of the water tank is reduced to the position where the flap cover 20 is partially exposed out of the water surface, the flap cover 20 starts to be closed, and the counterweight mechanism 60 rotates to the front limit position, so that the large-gear drainage is realized; alternatively, when the small button 52 is pressed to release the cover 20, the small drainage is realized.
In the initial state of the drain valve and water tank device of the present invention, referring to fig. 5, the water level of the water tank is the working water level, the flap cover 20, the base 10 and the weight mechanism 60 are located below the water level, the weight mechanism 60 is located at the front limit, and the flap cover 20 closes the drain port 11. The first transmission portion 71 of the stopper 70 is tilted, the stopper surface 72 naturally droops, the second transmission portions 43 of the transmission levers 41 are tilted, and the pull-up wires 42 at the other ends of the transmission levers 41 are in a loose state.
The small-gear drainage function of the drainage valve:
referring to fig. 6 and 8, when the small-sized button 52 is pressed down and presses the first transmission portion 71 of the transmission rod 41, the other end of the transmission rod 41 tilts up, the pulling wire 42 is pulled to lift the flap cover 20, and when the flap cover 20 is opened to the second opening position, the counterweight block 62 of the counterweight mechanism 60 is blocked by the blocking surface 72 of the blocking member 70, the flap cover 20 stops rotating, the flap cover 20 also stops rotating when being blocked by the first limiting block 64, and water is discharged through the water outlet 11.
In this state, the weight of the weight block 62 has a large force arm relative to the rotation shaft of the racket cover 20, so that the torque thereof is larger than the torque generated by the buoyancy of the racket cover 20 and the air chamber 22, and thus the racket cover 20 falls down after the key is released, and returns to the initial state after falling down.
Referring to fig. 8, G represents the net weight (buoyancy removed) of the weight block 62 and the connecting rod 63, F represents the resultant force of the buoyancy of the entire racket cover 20 and the air chamber 22 (excluding the weight mechanism) minus the gravity, L1 represents the moment arm of G, and L2 represents the moment arm of F, which satisfies the following conditions:
G·L1>F·L2
that is, the moment of the net weight of the weight block 62 is greater than the moment of the net buoyancy of the flap cover 20 and the air chamber 22, so that the flap cover 20 falls down.
After the small-gear drainage is finished, the flap cover 20 falls to the drainage port 11 of the base 10 and stops, the water level stops falling, which is called the small-gear drainage rear water level, referring to fig. 7, at this time, the rotating rod 61 is in a stable state of front limit, the water inlet valve of the water tank works to feed water, and the water level rises to the working water level.
The big grade drainage function of drain valve:
when the large-range key 51 is pressed down and the first transmission part 71 and the second transmission part 43 of the transmission rod 41 are pressed down, the other end of the transmission rod 41 is tilted, the racket cover 20 is lifted up by pulling the lifting wire 42, and the stop surface 72 of the stop member 70 is lifted up, the arrangement block of the weight mechanism 60 is not blocked. Since the counterweight mechanism 60 is not blocked, the flap cover 20 is opened to the maximum opening degree, i.e., the first opening position, and the rotating rod 61 of the counterweight mechanism 60 continues to rotate under the inertia effect, and rotates from the front limit state to the rear limit state, see fig. 9.
Since the weight of the weight block 62 has a small force arm relative to the rotation shaft of the flap cover 20 in this state, the torque thereof is smaller than the torque generated by the buoyancy of the flap cover 20 and the air chamber 22 (if the weight runs to the other side of the rotation shaft, even if the torque of the weight runs to one direction), so that the flap cover 20 maintains the open state of the maximum opening degree, water is discharged from the water discharge port 11, and the water level begins to drop.
After the large-gear button 51 is released, the large-gear button 51 is bounced and reset under the action of the elastic member 54, the other end of the transmission rod 41 sags under the action of gravity, the pulling wire 42 releases the flap cover 20, and the stop surface 72 of the stop member 70 also falls under the action of gravity.
When the water level continues to drop, referring to fig. 10 and 11, as the flap cover 20 is partially exposed to the water surface, the buoyancy drops, and the flap cover 20 begins to drop, and the weight block 62 is lower in height because the weight mechanism 60 is in the rear limit state, so that the stop surface 72 of the stop 70 does not stop the dropping process.
Referring specifically to fig. 13, G represents the net weight (buoyancy removed) of the weight block 62 and the connecting rod 63, F represents the resultant force of the buoyancy of the entire racket cover 20 and the air chamber 22 (excluding the weight mechanism) minus the gravity, L3 represents the moment arm of G, and L4 represents the moment arm of F, which includes:
G·L3<F·L4
that is, since the torque of the net weight of the weight block 62 is smaller than the torque of the net buoyancy of the flap cover 20 and the air chamber 22, the flap cover 20 will always maintain the maximum opening degree until the water level drops to a level where the flap cover 20 is partially exposed to the water surface, so that the buoyancy is reduced, and the flap cover will not start to fall.
Referring to fig. 12, the flap cover 20 falls to the water outlet 11 of the base 10 and stops, and the water level stops falling, which is called the water level after the large-range water discharge; the counterweight mechanism 60 is in an unstable state of rear limit, and can rotate forward under the action of gravity, and finally becomes in a front limit state, and the water inlet valve of the water tank feeds water, so that the water level rises to the working water level.
In addition, when the top button 51 and the bottom button 52 are pressed simultaneously, it activates the top drain function.
In the invention, the counterweight mechanism 60 is matched with the stop piece 70, the two drainage modes of the large gear button 51, the small gear button 52 and the flap cover are skillfully connected by rotation, when the small gear button 52 is pressed, the stop piece 70 does not rotate, the position of the counterweight mechanism 60 is limited, the drainage time is short at the moment, and the small gear drainage is realized; when the large-gear key 51 is pressed, the stop part 70 rotates, the position of the counterweight mechanism 60 is not limited, the drainage time is long, large-gear drainage is realized, the difference of the drainage quantity of large and small gears is obvious, the structure is simple, and the cost is low.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
