[0015] Such as Figures 1-5A hidden drain valve opening for pool cleaning as shown includes a valve body 1 and a sealing assembly installed inside the valve body 1. A drain pipe 3 is movably installed inside the valve body 1. Both the valve body 1 and the drain pipe 3 are cylindrical. The sealing assembly includes a movable block 6, a fixed rod 5 and a torsion spring 9. A mating groove 7 is formed at the bottom of the outer wall of the drain pipe 3. The fixed rod 5 is fixedly installed inside the valve body 1. One end of the movable block 6 is perforated and sleeved on the fixed rod 5. A torsion spring 9 is installed inside the perforation of the movable block 6. The torsion spring 9 is sleeved on the fixed rod 5. One end of the torsion spring 9 is fixedly connected to the movable block 6, and the other end is fixedly connected to the fixed rod 5. The end of the movable block 6 away from the fixed rod 5 is embedded inside the mating groove 7. A plurality of hollow slots are formed on the outer wall of the valve body 1. A spring 8 is fixedly installed at the bottom of the valve body 1. The top end of the spring 8 is fixedly connected to the bottom outer wall of the drain pipe 3.

[0016] An arc-shaped groove is formed at the bottom of the end of the movable block 6 away from the fixed rod 5. The grooved part of the movable block 6 is in close contact with the bottom edge of the mating groove 7. The end of the movable block 6 is arc-shaped. A plurality of vertically long strip-shaped water outlets are formed through the outer wall of the drain pipe 3. A sealing plate 2 is fixedly installed at the top of the drain pipe 3. The edge of the sealing plate 2 is in close contact with the inner wall of the valve body 1. The top surface of the sealing plate 2 is at the same horizontal plane as the top surface of the valve body 1. A sealing ring 10 is fixedly installed on the bottom outer wall of the sealing plate 2. The sealing ring 10 is embedded between the outer wall of the drain pipe 3 and the inner wall of the valve body 1. A limiting rod 4 is fixedly installed on the inner wall of the valve body 1. The length of the limiting rod 4 corresponds to the diameter of the valve body 1. The limiting rod 4 passes through two symmetrically arranged water outlets on the outer wall of the drain pipe 3.

[0017] Embodiment: In the initial state, the sealing plate 2 is at the same plane as the top end of the valve body 1. The torsion spring 9 always exerts a torsion force on the movable block 6. The movable block 6 is engaged with the mating groove 7, so that the drain pipe 3 is retracted inside the valve body 1 in the initial state, and the spring 8 is in a state of being compressed and contracted by the drain pipe 3. The valve body 1 is installed at the drain channel opening of the pool. When the operator needs to drain water, press the sealing plate 2. The sealing plate 2 drives the drain pipe 3 to descend, further compressing the spring 8, so that the spring 8 further accumulates elastic potential energy. The upper edge of the mating groove 7 will press down the end of the movable block 6, causing the movable block 6 to flip downward. The torsion spring 9 is distorted. As the position of the mating groove 7 continuously descends, the end of the movable block 6 will be extruded out of the area of the mating groove 7. Then the operator releases the sealing plate 2. The spring 8 will quickly lift the drain pipe 3 upward, and the mating groove 7 will also move upward quickly. When the movable block 6 is driven by the torsion spring 9 to flip and reset, the position of the drain pipe 3 is already above the movable block 6. When the drain pipe 3 slides upward, the limiting rod 4 will control the sliding direction of the drain pipe 3, so that the drain pipe 3 slides vertically upward. After the drain pipe 3 rises, the pool can be drained. Water enters the valve body 1 through the drain outlet of the drain pipe 3, and then enters the drain channel through the hollow slots of the valve body 1 for drainage.

[0018] After the drainage work is completed, the operator presses the sealing plate 2 to reset the drain pipe 3. After the bottom of the drain pipe 3 touches the movable block 6, the movable block 6 is pressed down. Since there is a spring 8 at the bottom of the drain pipe 3 to provide resistance, the pressing speed of the operator is relatively slow. Therefore, when the movable block 6 enters the area of the mating groove 7, the torsion spring 9 drives the movable block 6 to flip, and the end of the movable block 6 opens and closes again with the bottom edge of the mating groove 7. The operator can clearly feel the sound and vibration when the movable block 6 flips and contacts the edge of the mating groove 7. At this time, the sealing plate 2 is successfully reset, and the sealing ring 10 plays a role in sealing the gap.

[0019] It should be noted that the parts not involved in the present utility model are the same as or can be implemented by the prior art; various drives in the present utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in cooperation with connecting rods, guide rods, etc., and are not limited to the descriptions in the specification and the structures in the drawings.

[0020] The above-described embodiments merely represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
