[0004] To achieve the above objectives, the technical solution of the present invention provides a water storage and drainage device, including an installation platform, a water storage tank on the installation platform, a drain outlet on the water storage tank, and a drain hose on the drain outlet. It also includes: an installation hole on the installation platform, a control component on the installation hole whose height can be adjusted by a positioning device, and a connecting ring on the control component for the drain hose to pass through. The portion of the drain hose passing through the connecting ring is in an inverted U-shape.

When the lower end of the upper locking block abuts against the locking block, the lower locking block does not contact the locking block.
[0007] A further improvement is that the length of the upper end of the lower card block is longer than the length of the lower end of the upper card block.
[0008] A further improvement is that the elastic device includes: a mounting groove on the connecting plate and a spring in the mounting groove, one end of the spring abutting the bottom of the mounting groove and the other end abutting the locking block.

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0017] like Figures 1-8 As shown, a water storage and drainage device includes an installation platform 1, a water storage tank 2 on the installation platform 1, a drain outlet 3 on the water storage tank 2, and a drain hose 4 on the drain outlet 3. It also includes: an installation hole 5 on the installation platform 1, a control component 6 on the installation hole 5 whose height can be adjusted by a positioning device, and a connecting ring 7 on the control component 6 for the drain hose 4 to pass through. The part of the drain hose 4 that passes through the connecting ring 7 is inverted U-shaped. The control component 6 adjusts the height of the inverted U-shaped part of the drain hose 4 to control the water storage and drainage. The drain hose 4 is a stainless steel hose, a metal hose, a corrugated drain pipe, or a PVC plastic hose. The control component 6 can be a control rod or the faucet itself. If the control component 6 is the faucet itself, then the mounting hole 5 is the faucet mounting hole 5. In order to form an effective water seal when not in the drainage state and prevent the backflow of odors, insects and rodents, the drainage hose 4 is supported by the connecting ring 7 to form an inverted U-shape, and water column can be retained in the pipe to block the airflow. In order to achieve rapid siphon drainage during drainage, the inverted U-shaped top is lowered by adjusting the control component 6, which fills the pipe with continuous water flow, expels air, triggers the siphon effect, and greatly improves the drainage speed. The control component 6 can be adjusted up and down and locked via the positioning device. When adjusted down, the connecting ring 7 moves down accordingly, the inverted U-shaped top is lowered, and water fills this section of the pipe under gravity to form a continuous water flow, and the siphon is established by itself. When adjusted up, air enters and the siphon is destroyed, but some water is still retained to maintain the water seal.
[0018] Furthermore, as an optional implementation, in order to conveniently and reliably adjust and fix the installation height of the control component 6, the positioning device includes: a connecting plate 8 located at the mounting hole 5 under the mounting platform 1, a sliding plate 9 located on the control component 6, a sliding groove 10 located on the connecting plate 8 that matches the sliding plate 9, and a limiting plate 11 located on the connecting plate 8 that abuts against the sliding plate 9. At least one engaging device is also provided between the connecting plate 8 and the sliding plate 9. The connecting plate 8 is fixed under the mounting platform 1, and the sliding plate 9 slides up and down in the sliding groove 10 with the control component 6. The limiting plate 11 limits the maximum displacement. The locking device can fix the sliding plate 9 and the connecting plate 8 at one or more positions on the sliding path. Users can move the control piece 6 in a specific direction to adjust the height. Once in place, it is locked by a locking device to prevent it from coming loose.
[0019] Furthermore, as an optional implementation, in order to achieve a locking mechanism with a specific sequence of actions, the locking device includes: a locking groove 12 on the connecting plate 8 communicating with the sliding groove 10; locking blocks 13 respectively disposed on both sides of the locking groove 12 by elastic devices; an upper locking block 14 disposed on the sliding plate 9; a lower locking block 15 slidably disposed on the sliding plate 9; a cover plate 37 disposed on the connecting plate 8; and a clearance groove 16 disposed on the cover plate 37 for avoiding the connection between the control member 6 and the sliding plate 9. The upper locking block 14 has a first oblique angle 17 on its upper side, the lower locking block 13 has a second oblique angle 18 on its lower side, and the lower locking block 15 has a third oblique angle 19 on its lower side. The lower end of the upper locking block 14 is larger than the upper end of the locking block 13, the lower end of the lower locking block 15 is smaller than the upper end of the locking block 13, and the upper end of the lower locking block 15 is smaller than the lower end of the locking block 13. When the lower end of the upper locking block 14 abuts against the locking block 13, the lower locking block 15 does not contact the locking block 13. The cover plate 37 is secured to the connecting plate 8 by screws; When the control component 6 moves the upper locking block 14 down to the position of the locking block 13, the lower end of the upper locking block 14, because its size is larger than the distance between the upper ends of the two locking blocks 13, will abut against the upper end surface of the locking block 13 and be supported by the locking block 13 to complete the fixation. At this time, the lower locking block 15 has not yet contacted the locking block 13. When unlocking is required, the control slide plate 9 moves up and the lower locking block 15 moves up. The upper end of the lower locking block 15 pushes open the locking block 13, thus passing over the locking block 13. Then the slide plate 9 moves down. At this time, the lower locking block 15 abuts against the upper locking block 14 under the action of the locking block 13. At the same time, the lower end of the lower locking block 15 pushes open the locking block 13, and the upper locking block 14 passes over the locking block 13 together. At this time, the height of the control piece 6 can be adjusted downward. To ensure that the lower card block 15 can be coordinated with the upper card block 14 when unlocking, the upper end of the lower card block 15 is longer than the lower end of the upper card block 14. The upper end of the lower locking block 15 has been lengthened, so the locking block 13 is less likely to collide with the upper locking block 14 when it is reset, thus improving the pass rate of the upper locking block 14. In order to provide a reliable and automatic reset force for the locking block 13, the elastic device includes: a mounting groove 20 provided on the connecting plate 8, and a spring 21 provided in the mounting groove 20, wherein one end of the spring 21 abuts against the bottom of the mounting groove 20 and the other end abuts against the locking block 13; When no external force is applied, the locking block 13 automatically remains in the extended state to receive the upper locking block 14; when pressure is applied, it can retract and reset after the external force disappears, thus realizing locking and releasing. To prevent the locking block 13 from coming out of the mounting groove 20 and to limit its maximum extension stroke, the mounting groove 20 is also provided with a first limiting block 22, and the locking block 13 is provided with a second limiting block 23 corresponding to the first limiting block 22. The sliding range of the locking block 13 is constrained to prevent it from dislodging due to the force of the spring 21 or external force, thus ensuring the stability and lifespan of the mechanism.
[0020] Furthermore, as an optional implementation, in order to provide another locking device, the locking device includes: a left baffle 24 and a right baffle 25 disposed on the sliding groove 10 to prevent the sliding plate 9 from disengaging; a rotating block 26 rotatably disposed on the sliding plate 9; the length and width of the rotating block 26 are inconsistent; the dimension between the left baffle 24 and the right baffle 25 matches the width dimension of the rotating block 26; and a steering device for controlling the rotation of the rotating block 26 is also provided between the rotating block 26 and the sliding groove 10. The steering device includes: a V-shaped groove 27 on the rotating block 26; a deflector block 28 on the left side of the sliding groove 10 for insertion into the V-shaped groove 27; a fourth oblique angle 29 on the right baffle 25 for abutting against the side of the rotating block 26 so that the rotating block 26 rotates; and a fifth oblique angle 30 on the left baffle 24 for avoiding the rotating block 26. In use, control the sliding plate 9 to move the rotating block 26 upwards, such as... Figure 4 As shown, at this time, the V-shaped groove 27 abuts against the deflector block 28, causing the rotating block 26 to rotate to its limit angle. Then, the sliding plate 9 drives the rotating block 26 to move downwards. At this point, the V-shaped groove 27 of the rotating block 26 will face the right baffle 25. Continuing to move downwards, the V-shaped groove 27 will collide with the right baffle 25, causing the rotating block 26 to rotate. Figure 5 As shown, one end of the rotating block 26 abuts against the right baffle 25 and the other end abuts against the left baffle 24, thus completing the positioning of the control component 6; like Figure 6 As shown, when it is necessary to move downward, the control slide plate 9 drives the rotating block 26 to move upward. At this time, the deflector block 28 hits the side of the rotating block 26, causing it to rotate. Then, the control slide plate 9 is moved downward again. At this time, the rotating block 26 hits the fourth oblique angle 29 and rotates under the action of the fourth oblique angle 29, gradually turning to the vertical direction. At this time, the height of the control component 6 can be adjusted downward.
[0021] To further improve the stability of the sliding plate 9 during movement, a stabilizing block 31 for improving the stability of the sliding plate 9 is also provided on the right side of the sliding groove 10.
[0022] Furthermore, as an optional implementation, in order to facilitate quick and reliable connection and replacement of the drain hose 4, a drain connector 32 is also provided on the drain outlet 3; A drain connector 32 is installed or integrally formed at the drain outlet 3. The drain connector 32 may have a sealing ring, a snap-fit or a thread, and the drain hose 4 is directly sleeved or screwed onto it. A standardized interface is provided, which allows the drain hose 4 to be easily and tightly connected to the drain outlet 3 to prevent water leakage and facilitate disassembly and maintenance.
[0023] Furthermore, as an optional implementation, in order to enable the device to be used on toilets, squat toilets and mop sinks, thereby enhancing its functionality, the control unit 6 is also connected to an external float valve 33, the external float valve 33 is also connected to a water supply pipe 34, the external float valve 33 is also connected to a water inlet pipe 35 for supplying water to the water storage tank 2, and the external float valve 33 is also provided with a float connector 36 connected to the water storage tank 2; The float connector 36 and the inlet pipe 35 are stainless steel hoses or metal hoses. External float valve 33 is existing technology. Although external float valves 33 purchased on the market may differ in shape and structure, they only need to be able to achieve the opening and closing function of external float valve 33. In use, fluid enters the external float valve 33 through the water supply pipe 34, and then enters the water storage tank 2 through the water inlet pipe 35 of the external float valve 33 for water storage. At the same time, the fluid flows into the float connector 36, which generates pressure on the float of the external float valve 33. When the water pressure in the water supply pipe 34 is equal to the water pressure in the float connector 36, water storage stops and the water storage is completed. When water needs to be changed, the user moves the control component 6 downward to trigger the siphon effect to discharge the stored water. Then, the control component 6 is reset to reset the external float valve 33. Furthermore, the user can adjust the height of the external float valve 33 on the control component 6, or the height of the connection between the float connector 36 and the water storage tank 2. Even further, multiple locking devices can be installed, allowing the control component 6 to be fixed at multiple heights. This allows the user to directly adjust the height of the external float valve 33 via the control component 6, thereby controlling the water level in the water storage tank 2. If the user wants to use it as a toilet or squat toilet, the water level should be adjusted to a low level, at which point the water storage tank will hold approximately 1L of water. If the user wants to use it as a mop sink, the water level should be adjusted to a high level, allowing the water storage tank to accumulate a large amount of water.
[0024] Working principle: Through the liftable control component 6 and connecting ring 7, one section of the drain hose 4 is lifted and constrained into an inverted U-shape; When storing water, the highest point of the inverted U-shaped pipe of the drain hose 4 is relatively high, which ensures that there is enough water in the water storage tank 2. When there is no water in the water storage tank 2, water is left in the drainage hose 4 to form a water seal, which prevents the backflow of odors and rodents in the pipe. When drainage is needed, the control component 6 is lowered, which causes the top of the inverted U-shaped part of the connecting ring 7 and the drainage hose 4 to move down below the water level. Under the action of gravity, the water in the water storage tank 2 fills this section of the pipe and discharges the internal air, establishing a continuous water flow, thereby triggering the siphon effect and causing the pool water to be drained quickly. When drainage is complete or the water seal needs to be restored, adjust control component 6 to be raised so that the inverted U-shaped top is above the water surface. Air enters the pipeline and breaks the siphon, but some water is still retained in the pipeline to continue to achieve water seal and prevent odor. The height adjustment and locking of control component 6 is achieved by the locking mechanism in the positioning device, which is easy to adjust.
