Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, specifically to a drainage device for a pool. Background Technology

[0002] Traditional bathroom fixtures include mop sinks and handwashing sinks. Handwashing sinks, often called basins, are indispensable fixtures in bathrooms, primarily used for washing hands and face. There are two main types of handwashing sinks on the market: freestanding and countertop. Freestanding handwashing sinks are more common in small bathrooms, offering a simple yet practical design.

[0003] Handwashing sinks are widely used in daily life, mainly to provide convenience for cleaning. They are often installed in home shower rooms, kitchens, laundry rooms, balconies and other places. They are also one of the most commonly used cleaning tools in public toilets, which can facilitate the washing of hands or items at any time to maintain hygiene.

[0004] A mop sink, also known as a mop basin, is a common cleaning fixture primarily used for washing mops. It is typically designed to be shallow and small with a moderate capacity to hold the water needed for washing mops and to temporarily store used mops and other cleaning tools.

[0005] Although the design of the plug head can achieve the effects of water storage and drainage, when it is necessary to discharge the sewage stored in the tank, it is necessary to reach into the tank to remove the plug head from the outlet. At this time, the hands come into direct contact with the sewage. For the sake of hand hygiene, it is also necessary to clean the hands in time. It is impossible to avoid contact between the hands and sewage when draining. Utility Model Content

[0006] The purpose of this utility model is to provide a drainage device for a pool body, addressing the defects and shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a drainage device for a pool body, comprising a pool body, a basin disposed on the pool body, and a drain outlet disposed on the basin, characterized in that: it further comprises a drain connector disposed at the lower end of the basin for discharging water from the basin, a drain hose disposed at the lower end of the drain connector for guiding drainage during drainage, a control component disposed on the pool body located on one side of the basin for rising or falling on the pool body when driven by an external force, a connecting ring disposed at one end of the control component for the drain hose to pass through, and an inverted U-shaped portion formed by the drain hose passing through the connecting ring for storing water in the basin when the water level is higher than the water level in the basin, and for discharging water from the basin when the water level is lower than the water level in the basin.

[0008] A further improvement is that the control component includes a connecting sleeve disposed on the pool body, a lifting block disposed within the connecting sleeve for rising or falling within the connecting sleeve when driven by an external force, a drive rod disposed on the lifting block for controlling the rising or falling of the lifting block within the connecting sleeve, an avoidance opening opened on the side end face of the connecting sleeve, and one end of the connecting ring disposed on the side end face of the lifting block.

[0009] A further improvement is the addition of a side fixing port on the connecting sleeve, which communicates with the clearance opening, to restrict the descent of the lifting block after it has risen.

[0010] A further improvement is that the lifting block includes a main block that can be lifted and lowered within the connecting sleeve, a water inlet connector on the main block, a water outlet connector on the main block, and a control valve core on the main block that communicates with the water inlet connector and the water outlet connector. The lower end of the drive rod is located on the valve stem portion of the control valve core, and one end of the connecting ring is located on the water inlet connector, which is situated in the clearance opening.

[0011] A further improvement is that the drive rod is provided with a water outlet channel, and the side end face of the drive rod is provided with a side end connector, which is connected to the water outlet channel, and the side end connector is connected to the water outlet connector through a connecting pipe.

[0012] A further improvement is that a lower end connector is provided on the drain connector, and the lower end connector is connected to the water outlet connector through a connecting pipe.

[0013] A further improvement is that the lower end of the drive rod is connected to the valve stem portion of the control valve core via bolts.

[0014] A further improvement is that there are two water inlet connectors, which are respectively located at the left and right ends of the main block.

[0015] A further improvement is that the pool body has a connecting hole for the connecting sleeve to pass through, and the connecting sleeve is provided with a mounting platform for clearance fitting with the connecting hole. A connecting threaded sleeve is threaded onto the mounting platform, and the diameter of the mounting platform is smaller than the diameter of the connecting sleeve.

[0016] A further improvement is that a drain connection column for drainage is provided on the basin body inside the drain outlet, the drain connection column has a threaded surface on its periphery, a connecting sleeve is provided on the drain connection column below the basin body, the connecting sleeve is threadedly connected to the threaded surface, and the drain connector is threadedly connected to the threaded surface.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When it is necessary to make the basin achieve the purpose of water storage, the control component is pulled upward to drive the connecting ring to rise, which in turn drives the inverted U-shaped part of the drain hose to rise. At this time, the inverted U-shaped part is located in the high position of the basin. When water flows into the basin, due to the high height of the inverted U-shaped part, the water cannot be discharged from the drain hose. As long as the water level in the basin is lower than the inverted U-shaped part, the water can be stored in the basin to achieve the water storage effect. If it is necessary to discharge the sewage stored in the basin, the control component is pressed down on the main body of the basin, which drives the inverted U-shaped part of the drain hose to descend through the connecting ring until the inverted U-shaped part is lower than the liquid level in the basin. Then, the water in the basin is discharged outward through the drain hose. By controlling the control component located on the main body of the basin, the functions of water storage and drainage can be achieved without putting hands into the sewage in the basin. This can avoid contact between hands and sewage during drainage, ensuring hand hygiene. Attached Figure Description

[0036] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0037] See Figures 1 to 4 As shown, the technical solution adopted in this specific embodiment is: Example 1

[0038] A drainage device for a pool includes a pool body 1, a basin 2 disposed on the pool body 1, a drain outlet 3 opened on the basin 2, a drain connector 4 disposed at the lower end of the basin 2 for draining water from the basin 2, a drain hose 5 disposed at the lower end of the drain connector 4 for guiding drainage when the drain connector 4 drains water, a control component disposed on the pool body 1 on one side of the basin 2 for raising or lowering the pool body 1 when driven by an external force, a connecting ring 6 disposed at one end of the control component for the drain hose 5 to pass through, and an inverted U-shaped portion 7 formed by the drain hose 5 passing through the connecting ring 6 for storing water in the basin 2 when the water level is higher than the water level in the basin 2, and for draining water from the basin 2 when the water level is lower than the water level in the basin 2.

[0039] The pool body 1 can be a bathtub, washbasin, mop sink, etc. The pool body 1 and basin 2 are integrally formed. The drain outlet 3 is perforated and integrally formed with the basin 2. The drain connector 4 is connected via a flange, a nested fit between a pipe socket and spigot, or a snap-fit ​​method. This connection method is the same as the traditional connection between a PVC hose and the sink outlet, and is existing technology, so it will not be described further. The drain hose 5 is a PVC hose or other plastic hose.

[0040] The control components include a connecting sleeve 8 disposed on the pool body 1, a lifting block 9 disposed within the connecting sleeve 8 for rising or falling within the connecting sleeve 8 when driven by an external force, a drive rod 10 disposed on the lifting block 9 for controlling the lifting block 9 to rise or fall within the connecting sleeve 8, and a clearance opening 11 opened on the side end face of the connecting sleeve 8. The lifting block 9 is a T-shaped block, the drive rod 10 is fixedly connected to the upper end of the lifting block 9, the side end of the lifting block 9 is located in the clearance opening 11, and one end of the connecting ring 6 is disposed on the side end of the lifting block 9.

[0041] A side fixing port 12, formed on the connecting sleeve 8 and connected to the clearance opening 11, is used to restrict the descent of the lifting block 9 after it rises. To improve the fixing effect on the lifting block 9, the side fixing port 12 allows the connecting ring 6 or the water inlet connector 14 to engage, thereby restricting the descent of the lifting block 9 within the connecting sleeve 8. Without the side fixing port 12, the connection state between the lifting block 9 and the connecting sleeve 8 is as follows: when the lifting block 9 is not driven by an external force, the friction between the inner wall of the connecting sleeve 8 and the lifting block 9 fixes the lifting block 9 within the connecting sleeve 8, thus achieving positional fixation of the inverted U-shaped portion 7.

[0042] During installation, first insert the drain connector 4 into the lower end of the basin body 2, then fold the drain hose 5 into the lower end of the drain connector 4. Install the connecting sleeve 8 onto the basin body 1. The connecting sleeve 8 can also be integrally formed with the basin body or installed with fasteners. Insert the drive rod 10, which is connected to the lifting block 9, into the connecting sleeve 8 from bottom to top until the drive rod 10 protrudes from the connecting sleeve 8, and the lifting block 9 is located inside the connecting sleeve 8. Install the connecting ring 6 into the clearance opening 11 on the side end face of the lifting block 9, or the connecting ring 6 can be integrally set with the lifting block 9. When the lifting block 9 rises and falls, the clearance opening 11 allows the connecting ring 6 to move with the lifting block 9. Then pull the drain hose 5 through the connecting ring 6, so that the drain hose 5 forms an inverted U-shaped part 7. Figure 4 As shown, the side fixing port 12 is provided on the connecting sleeve 8 and is connected to the uppermost end of the clearance opening 11.

[0043] The pool body 1 has a connecting hole 20 for the connecting sleeve 8 to pass through. The connecting sleeve 8 is provided with a mounting platform 21 for clearance fitting with the connecting hole 20. A connecting threaded sleeve 22 is threaded onto the mounting platform 21. The diameter of the mounting platform 21 is smaller than the diameter of the connecting sleeve 8. During installation, the mounting platform 21 of the connecting sleeve 8 is passed through the connecting hole 20, and then the connecting threaded sleeve 22 is threaded onto the mounting platform 21. The connecting sleeve 8 is fixed to the pool body 1 by the connecting threaded sleeve 22.

[0044] A drain connecting column 23 for drainage is provided on the basin body 2 inside the drain outlet 3. The drain connecting column 23 has a threaded surface (not shown in the figure) on its periphery. A connecting sleeve 24 is provided on the drain connecting column 23 below the basin body 2. The connecting sleeve 24 is threaded to the threaded surface (not shown in the figure). The drain connector 4 is threaded to the threaded surface (not shown in the figure). During installation, the lower connecting column is inserted into the drain outlet 3 of the basin body 2 from top to bottom. A limiting platform is provided at the upper end of the drain connecting column 23 to limit the continuous descent of the lower connecting column. The connecting sleeve 24 is screwed into the lower end of the drain connecting column 23 until it abuts against the lower end of the basin body 2, thus fixing the drain connecting column 23 in the drain outlet 3. To improve the sealing performance, a sealing ring can be fitted on the upper end of the connecting sleeve 24. When the connecting sleeve 24 abuts against the lower end of the basin body 2, the sealing ring seals the gap between the lower end of the basin body 2 and the connecting sleeve 24.

[0045] The working principle of this invention is as follows: When the basin 2 needs to be filled with water, the drive rod 10 is pulled upwards, which in turn raises the connecting ring 6 via the lifting block. This, in turn, raises the inverted U-shaped part 7 of the drain hose 5. At this time, the inverted U-shaped part 7 is located at the high position of the basin 2. When water flows into the basin 2, due to the high height of the inverted U-shaped part 7, the water cannot be discharged from the drain hose 5. As long as the height of the water flow in the basin 2 is lower than that of the inverted U-shaped part 7, the water can be stored in the basin 2 to achieve the water storage effect. When it is necessary to discharge the sewage stored in the basin 2, the pressure control component descends on the main body 1 of the basin, thereby driving the inverted U-shaped part 7 of the drain hose 5 to descend through the connecting ring 6 until the inverted U-shaped part 7 is lower than the liquid level in the basin 2. Then, the water in the basin 2 is discharged outward through the drain hose 5. By controlling the control component located on the main body 1 of the basin, the functions of water storage and drainage can be achieved without putting hands into the sewage in the basin 2. This eliminates the need for hands to come into contact with sewage during drainage, ensuring hand hygiene.

[0046] See Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the technical solution adopted in this specific embodiment is: Example 2

[0047] A drainage device for a pool includes a pool body 1, a basin 2 disposed on the pool body 1, a drain outlet 3 opened on the basin 2, a drain connector 4 disposed at the lower end of the basin 2 for draining water from the basin 2, a drain hose 5 disposed at the lower end of the drain connector 4 for guiding drainage when the drain connector 4 drains water, a control component disposed on the pool body 1 on one side of the basin 2 for raising or lowering the pool body 1 when driven by an external force, a connecting ring 6 disposed at one end of the control component for the drain hose 5 to pass through, and an inverted U-shaped portion 7 formed by the drain hose 5 passing through the connecting ring 6 for storing water in the basin 2 when the water level is higher than the water level in the basin 2, and for draining water from the basin 2 when the water level is lower than the water level in the basin 2.

[0048] The pool body 1 can be a bathtub, washbasin, mop sink, etc. The pool body 1 and basin 2 are integrally formed. The drain outlet 3 is perforated and integrally formed with the basin 2. The drain connector 4 is connected via a flange, a nested fit between a pipe socket and spigot, or a snap-fit ​​method. This connection method is the same as the traditional connection between a PVC hose and the sink outlet, and is existing technology, so it will not be described further. The drain hose 5 is a PVC hose or other plastic hose.

[0049] The control components include a connecting sleeve 8 disposed on the pool body 1, a lifting block 9 disposed within the connecting sleeve 8 for rising or falling within the connecting sleeve 8 when driven by an external force, a drive rod 10 disposed on the lifting block 9 for controlling the lifting block 9 to rise or fall within the connecting sleeve 8, an avoidance opening 11 opened on the side end face of the connecting sleeve 8, and one end of the connecting ring 6 disposed on the side end face of the lifting block 9.

[0050] A side fixing port 12, formed on the connecting sleeve 8 and connected to the clearance opening 11, is used to restrict the descent of the lifting block 9 after it rises. To improve the fixing effect on the lifting block 9, the side fixing port 12 allows the connecting ring 6, the water inlet connector 14, or the side end connector 18 to engage, thereby restricting the descent of the lifting block 9 within the connecting sleeve 8. Without the side fixing port 12, the connection state between the lifting block 9 and the connecting sleeve 8 is as follows: when the lifting block 9 is not driven by an external force, the friction between the inner wall of the connecting sleeve 8 and the lifting block 9 fixes the lifting block 9 within the connecting sleeve 8, thus achieving positional fixation of the inverted U-shaped portion 7.

[0051] During installation, first insert the drain connector 4 into the lower end of the basin body 2, then fold the drain hose 5 into the lower end of the drain connector 4. Install the connecting sleeve 8 onto the basin body 1. The connecting sleeve 8 can also be integrally formed with the basin body or installed with fasteners. Insert the drive rod 10, which is connected to the lifting block 9, into the connecting sleeve 8 from bottom to top until the drive rod 10 protrudes from the connecting sleeve 8, and the lifting block 9 is located inside the connecting sleeve 8. Install the connecting ring 6 into the clearance opening 11 on the side end face of the lifting block 9, or the connecting ring 6 can be integrally set with the lifting block 9. When the lifting block 9 rises and falls, the clearance opening 11 allows the connecting ring 6 to move with the lifting block 9. Then pull the drain hose 5 through the connecting ring 6, so that the drain hose 5 forms an inverted U-shaped part 7. Figure 4 As shown, the side fixing port 12 is provided on the connecting sleeve 8 and is connected to the uppermost end of the clearance opening 11.

[0052] The lifting block 9 includes a main block 13 that can be lifted and lowered within the connecting sleeve 8, a water inlet connector 14 disposed on the main block 13, a water outlet connector 15 disposed on the main block 13, and a control valve core 16 disposed on the main block 13 and connected to the water inlet connector 14 and the water outlet connector 15. The lower end of the drive rod 10 is disposed on the valve stem portion of the control valve core 16, and one end of the connecting ring 6 is disposed on the water inlet connector 14. The water inlet connector 14 is located in the clearance opening 11.

[0053] The drive rod 10 is provided with a water outlet channel 17, and the side end face of the drive rod 10 is provided with a side end connector 18. The side end connector 18 is connected to the water outlet channel 17, and the side end connector 18 is connected to the water outlet connector 15 through a connecting pipe.

[0054] The drain connector 4 is provided with a lower end connector 19, which is connected to the water outlet connector 15 via a connecting pipe. All connecting pipes are flexible hoses used for conveying water.

[0055] The lower end of the drive rod 10 is connected to the valve stem portion of the control valve core 16 by bolt 25.

[0056] There are two water inlet connectors 14, located at the left and right ends of the main body 13, respectively. When there are two water inlet connectors 14, they are connected to the cold water outlet and the hot water outlet (or pure water and purified water) respectively, and the control valve core 16 uses either a mixing valve core or a hot and cold water valve core. When there is only one, a standard single-outlet valve core is used. When the water is turned on, the water flowing from the outlet channel 17 flows towards the basin 2 end; when the water is turned off, it is closed by rotating 45 or 90 degrees. The control valve core 16 is connected to both the water inlet connector 14 and the water outlet connector 15. The number of clearance openings 11 and side fixing ports 12 corresponds to the number of water inlet connectors 14. The control valve core 16 is installed on the main body 13 by thread or embedding, similar to the installation method of a traditional faucet valve core.

[0057] The water inlet connector 14 can also be configured as one, in which case the water outlet connector 15 can be located at the side or bottom of the main block 13. When there are two water inlet connectors 14, the water outlet connector 15 is located at the side or bottom of the main block 13, preferably at the bottom.

[0058] The surfaces of the inlet connector 14, outlet connector 15, and lower connector 19 are all connected to the connecting pipe by threads.

[0059] The pool body 1 has a connecting hole 20 for the connecting sleeve 8 to pass through. The connecting sleeve 8 is provided with a mounting platform 21 for clearance fitting with the connecting hole 20. A connecting threaded sleeve 22 is threaded onto the mounting platform 21. The diameter of the mounting platform 21 is smaller than the diameter of the connecting sleeve 8. During installation, the mounting platform 21 of the connecting sleeve 8 is passed through the connecting hole 20, and then the connecting threaded sleeve 22 is threaded onto the mounting platform 21. The connecting sleeve 8 is fixed to the pool body 1 by the connecting threaded sleeve 22.

[0060] A drain connecting column 23 for drainage is provided on the basin body 2 inside the drain outlet 3. The drain connecting column 23 has a threaded surface (not shown in the figure) on its periphery. A connecting sleeve 24 is provided on the drain connecting column 23 below the basin body 2. The connecting sleeve 24 is threaded to the threaded surface (not shown in the figure). The drain connector 4 is threaded to the threaded surface (not shown in the figure). During installation, the lower connecting column is inserted into the drain outlet 3 of the basin body 2 from top to bottom. A limiting platform is provided at the upper end of the drain connecting column 23 to limit the continuous descent of the lower connecting column. The connecting sleeve 24 is screwed into the lower end of the drain connecting column 23 until it abuts against the lower end of the basin body 2, thus fixing the drain connecting column 23 in the drain outlet 3. To improve the sealing performance, a sealing ring can be fitted on the upper end of the connecting sleeve 24. When the connecting sleeve 24 abuts against the lower end of the basin body 2, the sealing ring seals the gap between the lower end of the basin body 2 and the connecting sleeve 24. The middle part of the drain connection column 23.

[0061] The working principle of this utility model is as follows: When it is necessary to achieve water storage in the basin 2, the drive rod 10 is pulled upward, which drives the connecting ring 6 to rise through the lifting block. This, in turn, causes the inverted U-shaped part 7 of the drain hose 5 to rise. At this time, the inverted U-shaped part 7 is located at the high position of the basin 2. When water flows into the basin 2, due to the high height of the inverted U-shaped part 7, the water cannot be discharged from the drain hose 5. As long as the water level in the basin 2 is lower than the inverted U-shaped part 7, the water can be stored in the basin 2 to achieve the water storage effect. If it is necessary to discharge the sewage stored in the basin 2, the control component is lowered on the main body 1, which drives the inverted U-shaped part 7 of the drain hose 5 to descend through the connecting ring 6 until the inverted U-shaped part 7 is lower than the liquid level in the basin 2. Water in basin 2 is discharged outward through drain hose 5. By controlling the control unit located on the main body of the basin 1, water storage and drainage can be achieved without putting hands into the sewage in basin 2, thus avoiding contact between hands and sewage during drainage and ensuring hand hygiene. To save installation space for the faucet on the basin, the drive rod 10 can be set as a water outlet device. By pushing the drive rod 10 back and forth, the valve stem of the control valve core 16 swings, thereby discharging water from the outlet connector 15 into the outlet channel 17. At this time, the shape and structure of the drive rod 10 are similar to the shape and joint of the elbow faucet, allowing water to be discharged from the outlet channel 17 into basin 2 for water storage. Thus, the structure of water outlet, water storage, and drainage is realized through a single drive rod 10. To achieve a liquid seal effect and prevent backflow of odor from drain hose 5, the water flow can be turned on after drainage, allowing some water to remain on drain hose 5. Example 3

[0062] See Figure 1 , Figure 2 , Figure 4 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the technical solution adopted in this specific embodiment is:

[0063] A drainage device for a pool includes a pool body 1, a basin 2 disposed on the pool body 1, a drain outlet 3 opened on the basin 2, a drain connector 4 disposed at the lower end of the basin 2 for draining water from the basin 2, a drain hose 5 disposed at the lower end of the drain connector 4 for guiding drainage when the drain connector 4 drains water, a control component disposed on the pool body 1 on one side of the basin 2 for raising or lowering the pool body 1 when driven by an external force, a connecting ring 6 disposed at one end of the control component for the drain hose 5 to pass through, and an inverted U-shaped portion 7 formed by the drain hose 5 passing through the connecting ring 6 for storing water in the basin 2 when the water level is higher than the water level in the basin 2, and for draining water from the basin 2 when the water level is lower than the water level in the basin 2.

[0064] The pool body 1 can be a bathtub, washbasin, mop sink, etc. The pool body 1 and basin 2 are integrally formed. The drain outlet 3 is perforated and integrally formed with the basin 2. The drain connector 4 is connected via a flange, a nested fit between a pipe socket and spigot, or a snap-fit ​​method. This connection method is the same as the traditional connection between a PVC hose and the sink outlet, and is existing technology, so it will not be described further. The drain hose 5 is a PVC hose or other plastic hose.

[0065] The control components include a connecting sleeve 8 disposed on the pool body 1, a lifting block 9 disposed within the connecting sleeve 8 for rising or falling within the connecting sleeve 8 when driven by an external force, a drive rod 10 disposed on the lifting block 9 for controlling the lifting block 9 to rise or fall within the connecting sleeve 8, and an avoidance opening 11 opened on the side end face of the connecting sleeve 8, with one end of the connecting ring 6 disposed on the side end face of the lifting block 9 and located in the avoidance opening 11.

[0066] A side fixing port 12, formed on the connecting sleeve 8 and connected to the clearance opening 11, is used to restrict the descent of the lifting block 9 after it rises. To improve the fixing effect on the lifting block 9, the side fixing port 12 allows the connecting ring 6 or the water inlet connector 14 to engage, thereby restricting the descent of the lifting block 9 within the connecting sleeve 8. Without the side fixing port 12, the connection state between the lifting block 9 and the connecting sleeve 8 is as follows: when the lifting block 9 is not driven by an external force, the friction between the inner wall of the connecting sleeve 8 and the lifting block 9 fixes the lifting block 9 within the connecting sleeve 8, thus achieving positional fixation of the inverted U-shaped portion 7.

[0067] During installation, first insert the drain connector 4 into the lower end of the basin body 2, then fold the drain hose 5 into the lower end of the drain connector 4. Install the connecting sleeve 8 onto the basin body 1. The connecting sleeve 8 can also be integrally formed with the basin body or installed with fasteners. Insert the drive rod 10, which is connected to the lifting block 9, into the connecting sleeve 8 from bottom to top until the drive rod 10 protrudes from the connecting sleeve 8, and the lifting block 9 is located inside the connecting sleeve 8. Install the connecting ring 6 into the clearance opening 11 on the side end face of the lifting block 9, or the connecting ring 6 can be integrally set with the lifting block 9. When the lifting block 9 rises and falls, the clearance opening 11 allows the connecting ring 6 to move with the lifting block 9. Then pull the drain hose 5 through the connecting ring 6, so that the drain hose 5 forms an inverted U-shaped part 7. Figure 4 As shown, the side fixing port 12 is provided on the connecting sleeve 8 and is connected to the uppermost end of the clearance opening 11.

[0068] The lifting block 9 includes a main block 13 that can be lifted and lowered within the connecting sleeve 8, a water inlet connector 14 disposed on the main block 13, a water outlet connector 15 disposed on the main block 13, and a control valve core 16 disposed on the main block 13 and connected to the water inlet connector 14 and the water outlet connector 15. The lower end of the drive rod 10 is disposed on the valve stem portion of the control valve core 16, and one end of the connecting ring 6 is disposed on the water inlet connector 14. The water inlet connector 14 is located in the clearance opening 11.

[0069] The drain connector 4 is provided with a lower end connector 19, which is connected to the water outlet connector 15 via a connecting pipe. All connecting pipes are flexible hoses used for conveying water.

[0070] The lower end of the drive rod 10 is connected to the valve stem portion of the control valve core 16 by bolt 25.

[0071] There are two water inlet connectors 14, located at the left and right ends of the main body 13, respectively. When there are two water inlet connectors 14, they are connected to the cold water outlet and the hot water outlet (or pure water and purified water) respectively, and the control valve core 16 uses either a mixing valve core or a hot and cold water valve core. When there is only one, a standard single-outlet valve core is used. The control valve core 16 is connected to both the water inlet connector 14 and the water outlet connector 15. The number of clearance openings 11 and side fixing ports 12 corresponds to the number of water inlet connectors 14. The control valve core 16 is installed on the main body 13 by threading or embedding, similar to the installation method of a traditional faucet valve core.

[0072] The water inlet connector 14 can also be configured as one, in which case the water outlet connector 15 can be located at the side or bottom of the main block 13. When there are two water inlet connectors 14, the water outlet connector 15 is located at the side or bottom of the main block 13, preferably at the bottom.

[0073] The pool body 1 has a connecting hole 20 for the connecting sleeve 8 to pass through. The connecting sleeve 8 is provided with a mounting platform 21 for clearance fitting with the connecting hole 20. A connecting threaded sleeve 22 is threaded onto the mounting platform 21. The diameter of the mounting platform 21 is smaller than the diameter of the connecting sleeve 8. During installation, the mounting platform 21 of the connecting sleeve 8 is passed through the connecting hole 20, and then the connecting threaded sleeve 22 is threaded onto the mounting platform 21. The connecting sleeve 8 is fixed to the pool body 1 by the connecting threaded sleeve 22.

[0074] A drain connecting column 23 for drainage is provided on the basin body 2 inside the drain outlet 3. The drain connecting column 23 has a threaded surface (not shown in the figure) on its periphery. A connecting sleeve 24 is provided on the drain connecting column 23 below the basin body 2. The connecting sleeve 24 is threaded to the threaded surface (not shown in the figure). The drain connector 4 is threaded to the threaded surface (not shown in the figure). During installation, the lower connecting column is inserted into the drain outlet 3 of the basin body 2 from top to bottom. A limiting platform is provided at the upper end of the drain connecting column 23 to limit the continuous descent of the lower connecting column. The connecting sleeve 24 is screwed into the lower end of the drain connecting column 23 until it abuts against the lower end of the basin body 2, thus fixing the drain connecting column 23 in the drain outlet 3. To improve the sealing performance, a sealing ring can be fitted on the upper end of the connecting sleeve 24. When the connecting sleeve 24 abuts against the lower end of the basin body 2, the sealing ring seals the gap between the lower end of the basin body 2 and the connecting sleeve 24.

[0075] The working principle of this invention is as follows: When the basin 2 needs to be filled with water, the drive rod 10 is pulled upwards, which in turn raises the connecting ring 6 via the lifting block. This, in turn, raises the inverted U-shaped part 7 of the drain hose 5. At this time, the inverted U-shaped part 7 is located at the high position of the basin 2. When water flows into the basin 2, due to the high height of the inverted U-shaped part 7, the water cannot be discharged from the drain hose 5. As long as the height of the water flow in the basin 2 is lower than that of the inverted U-shaped part 7, the water can be stored in the basin 2 to achieve the water storage effect. When it is necessary to discharge the sewage stored in the basin 2, the pressure control component descends on the main body 1 of the basin, thereby driving the inverted U-shaped part 7 of the drain hose 5 to descend through the connecting ring 6 until the inverted U-shaped part 7 is lower than the liquid level in the basin 2. Then, the water in the basin 2 is discharged outward through the drain hose 5. By controlling the control component located on the main body 1 of the basin, the functions of water storage and drainage can be achieved without putting hands into the sewage in the basin 2. This eliminates the need for hands to come into contact with sewage during drainage, ensuring hand hygiene.

[0076] To save space on the sink, a faucet can be omitted. Water is connected to the lower connector 19 of the drain connector 4 via the outlet connector 15, allowing water to flow upwards from the bottom of the basin 2, creating a water storage effect. This eliminates the need for a faucet on the countertop, allowing the basin 2 to fill with water. When drainage is needed, pressing down the drive rod 10 lowers the drain hose 5, allowing water to drain from the basin 2. This structure can be used in washing sinks, especially mop sinks, achieving water outlet, storage, and drainage through a single drive rod 10. To achieve a liquid seal and prevent backflow of odors from the drain hose 5, the water flow can be turned on after drainage, leaving some water on the drain hose 5.

[0077] See Figures 13 to 16 As shown, the technical solution adopted in this specific embodiment is: Example 4

[0078] A drainage device for a pool includes a pool body 1, a basin 2 disposed on the pool body 1, a drain outlet 3 opened on the basin 2, a drain connector 4 disposed at the lower end of the basin 2 for draining water from the basin 2, a drain hose 5 disposed at the lower end of the drain connector 4 for guiding drainage when the drain connector 4 drains water, a control component disposed on the pool body 1 on one side of the basin 2 for raising or lowering the pool body 1 when driven by an external force, a connecting ring 6 disposed at one end of the control component for the drain hose 5 to pass through, and an inverted U-shaped portion 7 formed by the drain hose 5 passing through the connecting ring 6 for storing water in the basin 2 when the water level is higher than the water level in the basin 2, and for draining water from the basin 2 when the water level is lower than the water level in the basin 2.

[0079] The pool body 1 can be a bathtub, washbasin, mop sink, etc. The pool body 1 and basin 2 are integrally formed. The drain outlet 3 is perforated and integrally formed with the basin 2. The drain connector 4 is connected via a flange, a nested fit between a pipe socket and spigot, or a snap-fit ​​method. This connection method is the same as the traditional connection between a PVC hose and the sink outlet, and is existing technology, so it will not be described further. The drain hose 5 is a PVC hose or other plastic hose.

[0080] The control components include a connecting plate 26 disposed on the pool body 1, a lifting block 9 disposed within the connecting plate 26 for rising or falling within the connecting plate 26 when driven by an external force, a drive rod 10 disposed on the lifting block 9 for controlling the lifting block 9 to rise or fall within the connecting plate 26, and a T-shaped slide groove 27 opened on the connecting plate 26. The lifting block 9 is a T-shaped block and is slidably disposed within the T-shaped slide groove 27. The drive rod 10 is fixedly connected to the upper end of the lifting block 9, and one end of the connecting ring 6 is disposed on the side end of the lifting block 9.

[0081] The back of the connecting plate 26 is provided with a positioning sliding hole 28, which is connected to the T-shaped sliding groove 27. A positioning rod 29 is slidably disposed on the connecting plate 26 within the positioning sliding hole 28. One end of the positioning rod 29 is a tapered surface. A fixing cover 30 is provided on the back of the connecting plate 26 at the end of the positioning sliding hole 28. A limiting plate 31 is provided on the other end of the positioning rod 29 within the fixing cover 30. The diameter of the limiting plate 31 is larger than the diameter of the positioning sliding hole 28. The fixing cover 30 is fixed to the back of the connecting plate 26 by adhesive or welding. A push spring 32 is provided between the limiting plate 31 and the positioning rod 29. The spring force of the pushing spring 32 is such that it can push the limiting plate 31 against the back of the connecting plate 26, thereby restricting the lifting block 9 from rising and falling at one end of the positioning rod 29. When water is stored in the drain hose 5, it can withstand the weight of the drain hose 5. When the driving rod 10 is pressed down by hand, it can retract the positioning rod 29 and the limiting plate 31, allowing the positioning rod 29 to release its restriction on the lifting block 9. The positioning sliding hole 28 can be one or two. When there is only one, it is located on the upper part of the connecting plate 26, allowing the positioning rod 29 to restrict the descent of the lifting block 9 when it rises to a high position. When there are two, the other positioning sliding hole 28 can be located at the lower position of the falling lifting block 9, and the lowering of the lifting block 9 by the positioning rod 29 keeps the lifting block 9 in the lower position.

[0082] During installation, first insert the drain connector 4 into the lower end of the basin body 2, then twist the drain hose 5 into the lower end of the drain connector 4, and install the connecting plate 26 on the main body of the pool body 1. The connecting plate 26 can also be integrally formed with the pool body or installed by fasteners. Insert the drive rod 10 connected to the lifting block 9 into the connecting plate 26 from bottom to top (align the T-shaped groove 27 with the T-shaped block of the lifting block 9) until the drive rod 10 protrudes from the connecting plate 26. Install the connecting ring 6 on the side end face of the lifting block 9, or the connecting ring 6 is integrally set with the lifting block 9. When the lifting block 9 rises and falls, the connecting ring 6 moves with the lifting block 9. Then pull the drain hose 5 through the connecting ring 6 so that the drain hose 5 forms an inverted U-shaped part 7.

[0083] The pool body 1 has a connecting hole 20 for the connecting plate 26 to pass through. The connecting plate 26 is provided with a mounting platform 21 for clearance fitting with the connecting hole 20. A connecting threaded sleeve 22 is threaded onto the mounting platform 21. The diameter of the mounting platform 21 is smaller than the diameter of the connecting plate 26. During installation, the mounting platform 21 of the connecting plate 26 is passed through the connecting hole 20, and then the connecting threaded sleeve 22 is threaded onto the mounting platform 21. The connecting plate 26 is fixed to the pool body 1 by the connecting threaded sleeve 22.

[0084] A drain connecting column 23 for drainage is provided on the basin body 2 inside the drain outlet 3. The drain connecting column 23 has a threaded surface (not shown in the figure) on its periphery. A connecting sleeve 24 is provided on the drain connecting column 23 below the basin body 2. The connecting sleeve 24 is threaded to the threaded surface (not shown in the figure). The drain connector 4 is threaded to the threaded surface (not shown in the figure). During installation, the lower connecting column is inserted into the drain outlet 3 of the basin body 2 from top to bottom. A limiting platform is provided at the upper end of the drain connecting column 23 to limit the continuous descent of the lower connecting column. The connecting sleeve 24 is screwed into the lower end of the drain connecting column 23 until it abuts against the lower end of the basin body 2, thus fixing the drain connecting column 23 in the drain outlet 3. To improve the sealing performance, a sealing ring can be fitted on the upper end of the connecting sleeve 24. When the connecting sleeve 24 abuts against the lower end of the basin body 2, the sealing ring seals the gap between the lower end of the basin body 2 and the connecting sleeve 24.

[0085] The working principle of this utility model is as follows: When the basin 2 needs to be filled with water, the drive rod 10 is pulled upwards, which in turn causes the connecting ring 6 to rise via the lifting block 9. This, in turn, causes the inverted U-shaped part 7 of the drain hose 5 to rise. At this time, the inverted U-shaped part 7 is located in the high position of the basin 2. The positioning rod 29 restricts the descent of the lifting block 9, thus positioning the inverted U-shaped part 7 in a high position. When water flows into the basin 2, because the height of the inverted U-shaped part 7 is relatively high, the water cannot be discharged from the drain hose 5. As long as the height of the water flow in the basin 2 is lower than that of the inverted U-shaped part 7, the water can be discharged. Water is stored in basin 2 to achieve the effect of water storage. If it is necessary to discharge the sewage stored in basin 2, the drive rod 10 is pressed down to drive the lifting block 9 to descend, thereby driving the inverted U-shaped part 7 of the drain hose 5 to descend through the connecting ring 6 until the inverted U-shaped part 7 is lower than the liquid level in basin 2. Then, the water in basin 2 is discharged outward through the drain hose 5. By controlling the control component located on the main body of the pool 1, the functions of water storage and drainage can be achieved without putting hands into the sewage in basin 2. This can avoid contact between hands and sewage during drainage, ensuring hand hygiene.
