The valve body 3 specifically comprises a valve housing 31 and a valve cover 32 which are penetrated up and down, a fixing frame is arranged on the base 1, and the valve housing 31 is attached to the fixing frame. The fixing frame specifically comprises a fixing rod 11 and a bracket 8, wherein the fixing rod 11 and the bracket 8 are arranged on the base 1 and extend upwards, one end of the bracket 8 is sleeved on the fixing rod 11 and can be designed to adjust the height according to actual needs, and the other end of the bracket 8 is provided with a C-shaped clamping groove 81 for clamping the valve casing 31. The valve housing 31 is cylindrical, the piston 4 is slidably disposed in the valve housing 31, the sliding direction of the piston 4 is up and down, and a Y-ring seal 42 is fitted around the outer periphery of the piston 4.

The detachable structure is matched between the bottom end of the transmission rod 41 and the flap cover 2, and before the flap cover 2 is turned down, the whole hydraulic control mechanism is caused to release the flap cover 2, and the flap cover 2 is turned down and closed by means of dead weight when the water drainage is finished. In this embodiment, the releasable structure specifically realizes the release when the flap cover is turned up by a certain angle (less than the maximum angle of the flap cover turning up), at this time, the buoyancy of the water in the toilet tank to the flap cover is greater than the water pressure, and the flap cover is continuously turned up under the action of the buoyancy until the flap cover is completely opened, so as to realize smooth drainage. In addition, the releasable structure can also realize releasing when the flap is turned up to the right position (namely, the flap turning-up angle reaches the maximum).

The closing state of the flap 2 is shown in fig. 4, at this time, the extension of the transmission rod 41 reaches the longest, and the elastic hook 6 is hooked with the fixed hook 7. The flap 2 is opened as shown in fig. 5, in which the extension of the transmission rod 41 is minimized and the elastic hook 6 is disengaged from the fixed hook 7.
The switching process of the closing state and the opening state of the flap cover 2 is as follows: the water inlet 311 of the valve body 3 is filled with water, and the water pressure drives the piston 4 to drive the transmission rod 41 to move upwards, and compresses the third elastic piece 5; with the upward movement of the transmission rod 41, the elastic hook 6 drives the fixed hook 7 to move upward, so that the flap 2 is turned up and opened as shown in fig. 6, thereby realizing drainage. When the flap 2 is turned up to a certain angle, the two elastic barbs 61 of the elastic hook 6 respectively slip out from one end of the fixed hook 7, so that the transmission rod 41 is separated from the flap 2, and the flap 2 is turned up continuously under the buoyancy of water until the flap is completely opened.

Example two
Referring to fig. 9 and 10, a drain valve capable of being opened hydraulically according to the present invention is different from the first embodiment in that: the first component is a clamping piece 9, the second component is a swinging piece 10 which is connected to the flap 2 in a vertical swinging way, and a first elastic piece which enables the swinging piece 10 to reset is connected between the swinging piece 10 and the flap.
In this embodiment, the swinging member 10 is a hinge-type rod, and is rotatably connected to the flap 2 in a lever manner, and the corner of the swinging member 10 is disposed upward. The clamping piece 9 is clamped or separated from one end of the swinging piece 10 under the drive of the transmission rod 41, specifically, in the closing state of the flap 2, the clamping piece 9 is clamped with one end of the swinging piece 10, and when the flap 2 is turned up and opened, the clamping piece 9 is separated from the swinging piece 10. The first elastic member 101 is specifically a spring, and is connected between the other end of the swinging member 10 and the flap 2.
When water is discharged, the valve body 3 is filled with water, the water pressure drives the piston 4 to drive the transmission rod 41 to move upwards, and the third elastic piece 5 is compressed; along with the upward movement of the transmission rod 41, the clamping member 9 drives the swinging member 10 to move upward, and gradually drives one end of the swinging member 10 to tilt upward, and the other end of the swinging member 10 gradually swings downward to compress the first elastic member 101. As the swinging member 10 moves upward, the flap 2 turns up. When the flap 2 is turned up by a certain angle, one end of the swinging member 10 is tilted up to the limit position and separated from the clamping member 9, so that the transmission rod 41 is separated from the flap 2, and the flap 2 is turned up continuously under the buoyancy of water until the flap is completely opened. The flap 2 is turned down by self weight to be closed after the drainage is finished. After the swinging member 10 is separated from the clamping member 9, one end of the swinging member 10 is reset downward by the restoring force of the first elastic member 101. When the valve body 3 stops water inflow, the piston 4 and the transmission rod 41 move downwards under the restoring force of the third elastic piece 5; as the transmission rod 41 moves downward, the clamping member 9 also moves downward, and is pushed down by the pushing force of the transmission rod 41 to press one end of the swinging member 10, and the two ends are finally clamped together, as shown in fig. 10, so as to prepare for the next drainage.
Example III
Referring to fig. 11-16, a drain valve capable of being opened by hydraulic pressure according to the present invention is different from the first and second embodiments in that: the first position is lower than the second position, the releasable structure comprises an extension part 21 arranged on the flap cover 2 and a compression bar 43 vertically and slidably arranged on a guide part 35, and the extension part 21 and the flap cover 2 are positioned on two opposite sides of the flap cover rotating shaft; the pressing rod 43 is pushed by the transmission rod 41 to press down the extension part 21, so that the flap 2 is turned up and opened, and a reset structure for promoting the pressing rod 43 to move up before the flap is turned down is matched between the pressing rod 43 and the guide part 35. The guide portion 35 is specifically disposed at the bottom end of the valve body 31. The extension part 21 is arranged to enable the flap 2 to form a lever structure, so that the two ends can swing up and down. The top surface of the extension part 21 is provided with a groove for receiving the pressing rod 43 to press downwards, and the bottom end of the groove penetrates through the bottom end of the extension part 21 to prevent water accumulation.
In this embodiment, the restoring structure includes a second elastic member 44 abutting between the pressing rod 43 and the guiding portion 35 to drive the pressing rod 43 to restore upward, and an elastic portion 431 disposed on the pressing rod 43 and configured to receive the downward pressing of the driving rod 41, where the elastic portion 431 is blocked by a fixing portion 351 disposed on the guiding portion 35 to generate an elastic shape when the pressing rod 43 moves downward by a preset distance, so that the driving rod 41 releases the elastic portion 431, that is, the driving rod 41 cannot continuously press the elastic portion 431 downward. The second elastic member 44 is specifically a spring, and is abutted between the bottom of the guiding portion 35 and the upper middle portion of the pressing rod 43.
In this embodiment, the water inlet 311 of the valve body 3 is higher than the water outlet 312, specifically, the water inlet 311 is located at the top end of the valve body 31, and the water outlet 312 is located at the lower part of the side surface of the valve body 31. The third elastic member 5 is abutted between the bottom end of the piston 4 and the bottom end of the valve body 3, and sleeved on the transmission rod 41.
When water is discharged, the valve body 3 is filled with water, the water pressure drives the piston 4 to drive the transmission rod 41 to move downwards, and the third elastic piece 5 is compressed; when the bottom end of the transmission rod 41 touches the elastic portion 431 at the top of the compression rod 43, the transmission rod 41 pushes the elastic portion 431 to drive the compression rod 43 to move downward and compress the second elastic member 44. When the bottom end of the plunger 43 reaches the extension 21, as the plunger 43 continues to move downward, the extension 21 will be depressed and urge the flap 2 upward as shown in fig. 13. When the flap 2 is turned up by a certain angle, the elastic portion 431 at the top of the pressing rod 43 is blocked by the fixing portion 351 on the guiding portion 35 to be elastically deformed to separate from the bottom end of the driving rod 41, and keeps point contact with the side wall of the driving rod 41 and slides relatively (the friction force is small and does not affect the continuous downward movement of the driving rod 41), so that the driving rod 41 cannot continuously push the pressing rod 43 to move downward, as shown in fig. 14. At this time, the pressing rod 43 moves upward under the restoring force of the second elastic member 44, as shown in fig. 15, so that the whole hydraulic control mechanism is completely separated from the flap 2, and the flap 2 continues to turn up until it is completely opened due to the buoyancy of the water. The flap 2 is turned down by self weight to be closed after the drainage is finished. When the valve body 3 stops water inflow, the piston 4 and the transmission rod 41 are reset upwards under the restoring force of the third elastic piece 5; when the transmission rod 41 is restored in place, the elastic portion 431 loses the limiting action of the side wall of the transmission rod 41 and is restored elastically, and finally returns to the state shown in fig. 12 to prepare for the next drainage.
