Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, specifically to a quantitative water intake device and a quantitative drinking cup. Background Technology

[0002] In existing water cup designs, drinking through a straw is a crucial method, widely used by young children, the elderly, and patients requiring special care. However, some patients, such as kidney transplant recipients, those with swallowing difficulties, or gout patients, should drink small amounts of water frequently, requiring careful control of each intake to ensure adequate hydration while preventing choking. Current metered drinking cups typically use internal partitions to divide the cup into a storage and drinking area. A valve controls the precise flow of water from the storage area to the drinking area. However, this process usually involves electric or air-cushioned mechanisms, and the water cannot be dispensed continuously until the water is fully dispensed. This cumbersome operation, coupled with the added space and cost of motors and air-cushions, results in a heavy cup and a poor user experience.

[0003] Patent application CN 217243670 U discloses an anti-choking, controlled-volume drinking cup, comprising a lid and a body. The lid and body are connected by a thread. A one-way volume control component is located within the inner cavity of the body. A rotary button is located at the bottom of the cup base. When the patient needs to drink, rotating the button causes a piston threaded rod to rotate, which in turn rotates the threaded tube, causing the piston baffle to rotate. The piston threaded rod rotates vertically along the cup, and the piston baffle follows suit, pushing water into the one-way volume control component. This drinking cup can quantitatively control the amount of water a patient ingests each time, ensuring a measured amount of water enters the patient's mouth through the inlet, preventing choking. However, the user must first rotate the button to allow water to enter the one-way volume control component, and then drink from the inlet, which involves two separate steps, is time-consuming, cumbersome, space-consuming, and prone to damage. Therefore, there is a need to develop a quantitative water absorption device that is simple to operate, saves time and effort, achieves quantitative water absorption, and prevents choking, as well as a quantitative drinking cup that is equipped with such a device. Summary of the Invention

[0004] To address the existing technical problems, this invention provides a quantitative water intake device and a quantitative drinking cup, which enables quantitative water intake and drinking to be completed in one step. The operation is simple, time-saving, and space-saving.

[0005] The technical solution of the present invention is: a quantitative water absorption device, comprising a shell, a suction nozzle, a quantitative sealing component assembly, and a one-way valve; the shell is a hollow sealed structure, the quantitative sealing component assembly is installed in the cavity of the shell and is sealed to the shell, the suction nozzle is provided on the upper side of the quantitative sealing component assembly and is installed on the top of the shell, the upper end of the shell is provided with a water outlet that communicates with the suction nozzle, the lower end of the shell is provided with a water inlet, and the one-way valve is installed at the water inlet; when the quantitative sealing component assembly is in the assembled state, the quantitative sealing component assembly and the shell form two mutually sealed cavities, and water cannot flow from the quantitative sealing component assembly; when the quantitative sealing component assembly is in the separated state, water can flow freely between the quantitative sealing component assemblies.

[0006] Furthermore, the suction nozzle has a structure that can extend and retract vertically, and the suction nozzle extends downward into the cavity of the housing.

[0007] Preferably, the metering sealing component assembly includes an upper floating valve and a lower floating valve. The upper floating valve is provided with a suction component I, and the lower floating valve is provided with a suction component II. The suction components I and II interact to generate an attractive force. When the metering sealing component assembly is in the assembled state, the attractive force of the suction components I and II causes the upper floating valve and the lower floating valve to attract and adhere to each other. When the metering sealing component assembly is in the separated state, the attractive force of the suction components I and II cannot maintain the mutual attraction and adhesion of the upper floating valve and the lower floating valve.

[0008] Furthermore, the upper floating valve is provided with a first water passage hole, which is located on the outside of the suction nozzle; the lower floating valve is provided with a second water passage hole, which does not overlap with the first water passage hole; when the metering sealing component assembly is in the assembled state, the first water passage hole is sealed to the upper surface of the lower floating valve, and the second water passage hole is sealed to the lower surface of the upper floating valve, preventing water from flowing through the first and second water passage holes; when the metering sealing component assembly is in the separated state, the first water passage hole is separated from the upper surface of the lower floating valve, and the second water passage hole is separated from the lower surface of the upper floating valve, allowing water to flow freely through the first and second water passage holes.

[0009] Furthermore, the lower floating valve is also provided with a limiting post, which passes through the first water passage hole; a top limiting platform is provided on the top inner wall of the housing, which is located outside the suction nozzle and corresponds to the position of the limiting post; the distance between the upper floating valve and the suction nozzle is the same as the distance between the limiting post and the top limiting platform.

[0010] Furthermore, a constraint structure is provided on the inner wall of the first water passage, and a limiting post is adapted to the constraint structure. The limiting post is slidably connected to the upper floating valve through the constraint structure. The upper end of the limiting post extends outward to form a boss, and the boss contacts and limits the upper end face of the constraint structure.

[0011] Furthermore, a bottom limiting support structure is provided at the bottom of the housing, which contacts the lower end of the lower floating valve and limits the initial position of the lower floating valve.

[0012] Furthermore, the quantitative sealing component assembly also includes an elastic component I, which is connected to the outside of the upper floating valve. The elastic component I is either fixedly and sealed to the housing or slidably and tightly sealed to it.

[0013] Furthermore, the quantitative sealing component assembly also includes an elastic component II, which is connected to the outside of the lower floating valve. The elastic component II is either fixedly sealed to the housing or slidably and tightly sealed to it.

[0014] Preferably, the metering sealing component assembly includes an upper floating valve and a lower floating valve. The upper and lower floating valves provide attraction through their own materials. When the metering sealing component assembly is in the assembled state, the attraction between the upper and lower floating valves causes them to attract and adhere to each other. When the metering sealing component assembly is in the separated state, the attraction between the upper and lower floating valves cannot maintain their mutual attraction and adhesion.

[0015] Preferably, the housing consists of an upper shell and a lower shell, which are sealed together to form a cavity; the suction nozzle is installed on the top of the upper shell, the upper end of the upper shell is provided with a water outlet, and the lower end of the lower shell is provided with a water inlet.

[0016] Preferably, the housing includes a column and a top cover. The column is an integrally formed structure and is a barrel-shaped structure with an open top. The top cover is provided on the top of the column, and the top cover and the column are sealed together. The suction nozzle is installed at the lower end of the top cover. The upper end of the top cover is provided with a water outlet, and the lower end of the column is provided with a water inlet.

[0017] A metered drinking cup includes a lid, a body, a straw, and a metered water intake device; the metered water intake device is installed between the lid and the body, a straw is installed below the inlet of the metered water intake device, the straw is connected to a one-way valve, and the outlet of the metered water intake device is sealed to the straw or the spout of the lid.

[0018] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0019] (1) The present invention, through the cooperation of the upper floating valve, the lower floating valve, the suction nozzle, the one-way valve and the shell, enables a certain amount of water to enter the shell for storage when using it for the first time. When using it for normal water intake, the water stored in the shell can be sucked out and a certain amount of water can be stored back in the shell through a single water intake action. The water intake and water intake actions are connected, eliminating the need for separate sequential operations. The operation is simple, time-saving, and the amount of water consumed each time is accurately measured. The power sources for drinking water are wide, such as human sucking, syringe pulling, air bag suction and electric suction.

[0020] (2) The quantitative drinking cup using the quantitative water suction device of the present invention allows the drinker to simultaneously drink and dispense a quantitative amount of water in one suction action during normal use, making the quantitative drinking action continuous and convenient to operate. It is especially suitable for young children, the elderly, and disabled persons who require special care. In addition, the amount of water for quantitative drinking can be adjusted by adjusting the distance between the upper floating valve and the suction nozzle, making the operation simple.

[0021] (3) It has a simple structure, occupies little space, and has a low cost. Attached Figure Description

[0046] The present invention will be further described in detail below with reference to specific embodiments.

[0047] Example 1

[0048] Reference Figure 1 and Figure 6 As shown, a metering water absorption device includes a housing, a suction nozzle 2, a metering sealing component assembly, and a one-way valve 3. The housing is a hollow, sealed structure. The metering sealing component assembly is installed in the cavity of the housing and is sealed to the housing. The suction nozzle 2 is provided on the upper side of the metering sealing component assembly and is installed on the top of the housing. The upper end of the housing is provided with a water outlet 5, which communicates with the suction nozzle 2. The lower end of the housing is provided with a water inlet 6, and the one-way valve 3 is installed at the water inlet 6. When the metering sealing component assembly is in the assembled state, the metering sealing component assembly and the housing form two mutually sealed cavities, and water cannot flow from the metering sealing component assembly. When the metering sealing component assembly is in the separated state, water can flow freely between the metering sealing component assemblies.

[0049] Furthermore, the suction nozzle 2 is a structure that can extend and retract vertically and spring back. The suction nozzle 2 extends downward into the cavity of the housing and is preferably made of a corrugated tubular soft material.

[0050] Furthermore, the quantitative sealing component assembly includes an upper floating valve 9 and a lower floating valve 11. The upper floating valve 9 is provided with a suction component I14, and the lower floating valve 11 is provided with a suction component II15. The suction components I14 and II15 interact to generate an attractive force. When the quantitative sealing component assembly is in the assembled state, the attractive force of the suction components I14 and II15 causes the upper floating valve 9 and the lower floating valve 11 to attract and adhere to each other. When the quantitative sealing component assembly is in the separated state, the attractive force of the suction components I14 and II15 cannot maintain the mutual attraction and adhesion between the upper floating valve 9 and the lower floating valve 11.

[0051] The suction components I 14 and II 15 work together to attract and adhere the upper floating valve 9 and the lower floating valve 11, unaffected by gravity and water pressure. The engagement of the suction components I 14 and II 15 can be, but is not limited to, magnetic attraction and attraction by materials with adsorption molecular properties. In this embodiment 1, the suction component I 14 is a magnet, and the suction component II 15 is an iron sheet. That is, the upper floating valve 9 contains a magnet, and the lower floating valve 11 contains an iron sheet.

[0052] Furthermore, the upper floating valve 9 is provided with a first water passage hole 10, which is located on the outside of the suction nozzle 2; the lower floating valve 11 is provided with a second water passage hole 13, which does not overlap with the first water passage hole 10; when the metering sealing component assembly is in the assembled state, the first water passage hole 10 is sealed to the upper surface of the lower floating valve 11, and the second water passage hole 13 is sealed to the lower surface of the upper floating valve 9, preventing water from flowing through the first water passage hole 10 and the second water passage hole 13; when the metering sealing component assembly is in the separated state, the first water passage hole 10 is separated from the upper surface of the lower floating valve 11, and the second water passage hole 13 is separated from the lower surface of the upper floating valve 9, allowing water to flow freely through the first water passage hole 10 and the second water passage hole 13.

[0053] The first water passage hole 10 and the suction nozzle 2 do not overlap. The diameter of the first water passage hole 10 is larger than the diameter of the limiting post 12, so the water passage area of ​​the first water passage hole 10 will not be completely blocked by the limiting post 12. Therefore, the lower floating valve 11 can move up and down without affecting the upper floating valve 9.

[0054] Furthermore, the housing is composed of an upper shell 1 and a lower shell 4, which are sealed together to form a cavity; the suction nozzle 2 is installed on the top of the upper shell 1, the upper end of the upper shell 1 is provided with a water outlet 5, and the lower end of the lower shell 4 is provided with a water inlet 6.

[0055] The connection methods between the upper shell 1 and the lower shell 4 include, but are not limited to, threaded connection, snap-fit ​​connection, bonding, insertion, silicone clamping, welding, interference fit and extrusion. In this embodiment 1, the upper shell 1 and the lower shell 4 are connected by snap-fit ​​connection to form a cavity that is large in the middle and small on the top and bottom sides.

[0056] Furthermore, the lower floating valve 11 is also provided with a limiting post 12, which passes through the first water passage hole 10; the upper shell 1 has a top limiting platform 20 on its top inner wall, which is located outside the suction nozzle 2 and corresponds to the position of the limiting post 12; the distance between the upper floating valve 9 and the suction nozzle 2 is the same as the distance between the limiting post 12 and the top limiting platform 20.

[0057] In this embodiment 1, there are a total of 3 limiting posts 12, which are evenly distributed along the circumference of the lower floating valve 11.

[0058] Furthermore, the quantitative sealing component assembly also includes an elastic component I16, which is connected to the outer side of the upper floating valve 9, and the outer edge of the elastic component I16 is fixedly and sealingly connected to the upper shell 1 and the lower shell 4.

[0059] Furthermore, the quantitative sealing component assembly also includes an elastic component II24, which is connected to the outer side of the lower floating valve 11, and the outer edge of the elastic component II24 is sealed and fixedly connected to the upper shell 1 and the lower shell 4.

[0060] The elastic components I16 and II24 are made of soft elastic material and have shapes including, but not limited to, sheet-like, planar corrugated, and spiral structures that are stretchable and resilient. In this embodiment 1, the elastic components I16 and II24 are corrugated discs.

[0061] The working process of the quantitative water absorption device in Example 1 is as follows:

[0062] During the initial water intake, in the first stage, when water is drawn upward through the outlet 5, the air in the suction nozzle 2 and the upper shell 1 is drawn away, reducing the pressure on the upper side of the upper floating valve 9. At this time, the metering sealing component assembly is in the assembled state (i.e., the initial state), with the upper floating valve 9 and the lower floating valve 11 tightly attached together. The metering sealing component assembly, the upper shell 1, and the lower shell 4 form two mutually sealed cavities. Due to the reduced pressure in the upper cavity, the upper floating valve 9 and the lower floating valve 11 move upward together, resulting in a decrease in the water pressure below the lower floating valve 11 in the lower shell 4. Water from the outside of the lower shell 4 then enters the inlet 6 and flows through the one-way valve 3 into the cavity between the lower floating valve 11 and the one-way valve 3 in the lower shell 4. At this time, the upper floating valve 9 and the lower floating valve 11 are in a state of water pressure and suction force. Under the suction force between component 14 and suction component II15, they move upwards together. Since the outer edges of elastic component I16 and elastic component II24 are fixed between the upper shell 1 and the lower shell 4, the movement of the upper floating valve 9 and the lower floating valve 11 causes elastic component I16 and elastic component II24 to deform until the upper floating valve 9 contacts the lower end of the suction nozzle 2. At this time, the limiting post 12 of the lower floating valve 11 just touches the top limiting platform 20 of the upper shell 1 (e.g., Figure 8 (As shown).

[0063] In the second stage, water continues to be drawn upward through outlet 5. The upper floating valve 9 continues to move upward and compress the suction nozzle 2, while the lower floating valve 11 is limited by the contact between the limiting post 12 and the top limiting platform 20, and no longer moves upward with the upper floating valve 9. The lower floating valve 11 gradually disengages from the upper floating valve 9, and the metering sealing component assembly enters a separated state (e.g., Figure 9 (As shown).

[0064] In the third stage, the negative pressure of upward water suction through outlet 5 continues. As the upper floating valve 9 continues to move upward until the suction nozzle 2 is compressed to its maximum extent, the upper floating valve 9 contacts the top limiting platform 20 and stops moving upward. At this point, the suction nozzle 2 is compressed to its maximum extent. In this stage, the second water passage 13 is no longer in contact with the upper floating valve 9, and water can flow freely from the second water passage 13 of the lower floating valve 11. The pressure on the upper and lower sides of the lower floating valve 11 is balanced, and it is no longer subjected to upward water pressure. Because the upper floating valve 9 and the lower floating valve 11 are separated, the suction between suction component I 14 and suction component II 15 becomes ineffective due to the increased distance, and can no longer attract and adhere the upper floating valve 9 and the lower floating valve 11. At this time, under the force generated by the deformation of elastic component II 24, the lower floating valve 11 moves downward until it returns to its original position. At this time, the suction at outlet 5 remains, the upper floating valve 9 contacts and seals with the suction stop nozzle 2, so the pressure on the lower side of the upper floating valve 9 is higher than the pressure inside the suction stop nozzle 2, keeping the upper floating valve 9 from falling off and preventing water from flowing into the suction stop nozzle 2 (e.g. Figure 10 As shown in the figure, the maximum amount of water that can be drawn at this time is the water absorption capacity of the metering water absorption device.

[0065] In the fourth stage, the suction at the outlet 5 is removed, and the negative pressure inside the suction nozzle 2 disappears instantly. At this time, water can flow freely from the first water passage 10. The pressure on the upper and lower sides of the upper floating valve 9 is balanced. Under the force generated by the deformation of the elastic component 16, the upper floating valve 9 moves downward until it returns to its original position and contacts the lower floating valve 11 to re-attract and adhere. The metering sealing component assembly returns to its combined state, and water cannot pass through the metering sealing component assembly. The metering sealing component assembly re-forms two mutually sealed cavities with the upper shell 1 and the lower shell 4.

[0066] Throughout the entire process from the first to the fourth stage, under the action of the one-way valve 3, the water can only flow into the device from the inlet 6 and cannot flow back, so the amount of water inside the metering water suction device will not decrease. At this time, the metered water (maximum suction capacity) is stored in the space between the upper shell 1 and the upper floating valve 9 for the next water suction action.

[0067] During normal water intake, water is drawn upwards through outlet 5. A fixed amount of water stored inside the upper shell 1 and above the upper floating valve 9 flows out through the suction nozzle 2 and outlet 5. Simultaneously, the pressure on the upper floating valve 9 and lower floating valve 11 decreases, and the metering sealing assembly is in the assembled state. If the metering sealing assembly moves upwards, water from outside the device will be drawn back into the area below the metering sealing assembly. This process repeats the initial water intake operation, thus achieving both the extraction of a fixed amount of water from outlet 5 and the re-storage of a fixed amount of water inside the device (water intake) in a single water intake cycle for the next operation.

[0068] The quantitative water intake device of Example 1 can adjust the amount of water to be dispensed by adjusting the distance between the upper floating valve 9 and the suction nozzle 2 of the upper shell 1, that is, the distance between the limiting column 12 and the top limiting platform 20. The quantitative calculation method is as follows: the diameter of the bottom of the internal space of the upper shell 1 is a, the diameter of the upper floating valve 9 is b, and the distance from the upper floating valve 9 to the suction nozzle 2 (or the distance from the limiting column 12 to the top limiting platform 20) is c. During the operation of the entire device from the first stage to the fourth stage, because the internal cross-section of the device is circular, the amount of water dispensed at one time is approximately equal to the volume of a frustum with an upper diameter of a, a lower diameter of b, and a height of c. The calculation formula is: V=1 / 3πc{(a / 2)²+(b / 2)²+ab / 4}. For example: if a=4cm, b=2cm, c=2cm, then the amount of water absorbed in a single dose is approximately: 1 / 3π2{(4 / 2)²+(2 / 2)²+4*2 / 4}≈9.19ml.

[0069] A metered drinking cup includes a cup lid, a cup body, a straw 18, and a metered water intake device; the metered water intake device is installed between the cup lid and the cup body, the straw 18 is installed on the lower side of the water inlet 6 of the metered water intake device, the straw 18 is connected to a one-way valve 3, and the upper side of the water outlet 5 of the metered water intake device is sealed to the straw or the mouthpiece of the cup lid.

[0070] Furthermore, the connection methods between the water outlet 5 and the straw or cup lid include, but are not limited to, threaded, snap-fit, adhesive, insertion, silicone clamping, welding, interference fit and compression. In this embodiment 1, the connection method is threaded, and the connection method between the water inlet 6 and the straw 18 is compression.

[0071] Example 2

[0072] Reference Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, a quantitative water absorption device includes a housing, a suction nozzle 2, a quantitative sealing component assembly, and a one-way valve 3. The housing is a hollow, sealed structure. The quantitative sealing component assembly is installed in the cavity of the housing and is sealed to the housing. The suction nozzle 2 is provided on the upper side of the quantitative sealing component assembly and is installed on the top of the housing. The upper end of the housing is provided with a water outlet 5, which communicates with the suction nozzle 2. The lower end of the housing is provided with a water inlet 6, and the one-way valve 3 is installed at the water inlet 6. When the quantitative sealing component assembly is in the combined state, the quantitative sealing component assembly and the housing form two mutually sealed cavities, and water cannot flow from the quantitative sealing component assembly. When the quantitative sealing component assembly is in the separated state, water can flow freely between the quantitative sealing component assemblies.

[0073] Furthermore, the suction nozzle 2 is a structure that can extend and retract vertically and spring back. The suction nozzle 2 extends downward into the cavity of the housing and is preferably made of a corrugated tubular soft material.

[0074] Furthermore, the quantitative sealing component assembly includes an upper floating valve 9 and a lower floating valve 11, the upper floating valve 9 being provided with a suction component I14, and the lower floating valve 11 being provided with a suction component II15. Figure 2 (Suction component I14 and suction component II15 are not shown in the figure). Suction component I14 and suction component II15 interact to generate an attractive force. When the metering sealing component assembly is in the combined state, the attractive force of suction component I14 and suction component II15 causes the upper floating valve 9 and the lower floating valve 11 to attract and adhere to each other. When the metering sealing component assembly is in the separated state, the attractive force of suction component I14 and suction component II15 cannot maintain the mutual attraction and adhesion of the upper floating valve 9 and the lower floating valve 11.

[0075] The suction components I14 and II15 work together to attract and adhere the upper floating valve 9 and the lower floating valve 11, unaffected by gravity or water pressure. The engagement of the suction components I14 and II15 can be achieved through magnetic attraction or attraction by materials possessing adsorption molecular properties. In this embodiment 2, the suction component I14 is a magnet, and the suction component II15 is an iron sheet. That is, the upper floating valve 9 contains a magnet, and the lower floating valve 11 contains an iron sheet.

[0076] Furthermore, the upper floating valve 9 is provided with a first water passage hole 10, which is located on the outside of the suction nozzle; the lower floating valve 11 is provided with a second water passage hole 13, which does not overlap with the first water passage hole 10; when the metering sealing component assembly is in the assembled state, the first water passage hole 10 is sealed to the upper surface of the lower floating valve 11, and the second water passage hole 13 is sealed to the lower surface of the upper floating valve 9, preventing water from flowing through the first water passage hole 10 and the second water passage hole 13; when the metering sealing component assembly is in the separated state, the first water passage hole 10 is separated from the upper surface of the lower floating valve 11, and the second water passage hole 13 is separated from the lower surface of the upper floating valve 9, allowing water to flow freely through the first water passage hole 10 and the second water passage hole 13.

[0077] The first water passage hole 10 and the suction nozzle 2 do not overlap. The diameter of the first water passage hole 10 is larger than the diameter of the limiting post 12, so the water passage area of ​​the first water passage hole 10 will not be completely blocked by the limiting post 12. Therefore, the lower floating valve 11 can move up and down without affecting the upper floating valve 9.

[0078] Furthermore, the housing is composed of an upper shell 1 and a lower shell 4, which are sealed together to form a cavity; the suction nozzle 2 is installed on the top of the upper shell 1, the upper end of the upper shell 1 is provided with a water outlet 5, and the lower end of the lower shell 4 is provided with a water inlet 6.

[0079] The connection methods between the upper shell 1 and the lower shell 4 include, but are not limited to, threaded connection, snap-fit ​​connection, bonding, insertion, silicone clamping, welding, interference fit and extrusion. In this embodiment 2, the upper shell 1 and the lower shell 4 are connected by snap-fit ​​connection to form a cavity that is large in the middle and small on the top and bottom sides.

[0080] Furthermore, the lower floating valve 11 is also provided with a limiting post 12, which passes through the first water passage hole 10; the upper shell 1 has a top limiting platform 20 on its top inner wall, which is located outside the suction nozzle 2 and corresponds to the position of the limiting post 12; the distance between the upper floating valve 9 and the suction nozzle 2 is the same as the distance between the limiting post 12 and the top limiting platform 20.

[0081] Furthermore, the quantitative sealing component assembly also includes an elastic component I16, which is connected to the outer side of the upper floating valve 9, and the outer edge of the elastic component I16 is fixedly and sealingly connected to the upper shell and the lower shell 4.

[0082] The elastic components I16 and II24 are made of soft elastic material and have shapes including, but not limited to, sheet-like, planar corrugated, and spiral structures that are stretchable and resilient. In this embodiment 2, the elastic component I16 is a corrugated disk.

[0083] Furthermore, a constraint structure 23 (such as...) is provided on the inner wall of the first water passage 10. Figure 17 As shown), the limiting post 12 is adapted to the constraint structure 23, and the limiting post 12 is slidably connected to the upper floating valve 9 through the constraint structure 23; the upper end of the limiting post 12 extends outward to form a boss 17, and the boss 17 contacts and limits the upper end face of the constraint structure 23; the bottom of the lower shell 4 is provided with a bottom limiting support structure 19, which contacts the lower end of the lower floating valve 11, and the bottom limiting support structure 19 limits the initial position of the lower floating valve 11.

[0084] In this embodiment 2, there are three limiting posts 12, evenly distributed along the circumference of the lower floating valve 11. The constraint structure 23 limits the limiting posts 12, ensuring that they can only move up and down and cannot sway or deflect horizontally. The lower floating valve 11 is mounted on the upper floating valve 9 via the limiting posts 12. As the limiting posts 12 move downward along the constraint structure 23, when the boss 17 contacts the upper end face of the constraint structure 23, the limiting posts 12 stop moving downward, thereby preventing the lower floating valve 11 from dislodging from the upper floating valve 9.

[0085] The working process of the quantitative water absorption device in Example 2 is as follows:

[0086] During the initial water intake, in the first stage, when water is drawn upwards through the outlet 5, the air in the suction nozzle 2 and the upper shell 1 is drawn away, reducing the pressure on the upper side of the metering sealing component assembly. At this time, the metering sealing component assembly is in the assembled state (i.e., the initial state), with the upper floating valve 9 and the lower floating valve 11 tightly pressed together. The metering sealing component assembly, the upper shell 1, and the lower shell 4 form two mutually sealed cavities. Due to the reduced pressure in the upper cavity, the upper floating valve 9 and the lower floating valve 11 move upwards together and stretch the elastic component 16, thereby reducing the water pressure on the lower side of the metering sealing component assembly inside the device, and allowing water to flow out from the outside of the lower shell 4. The water will enter the inlet 6 and flow through the one-way valve 3 into the cavity between the metering sealing component assembly and the one-way valve 3 inside the device; at this time, the upper floating valve 9 and the lower floating valve 11 of the metering sealing component assembly 21 will move upward together under the action of water pressure and the suction force between the suction component I14 and the suction component II15. Since the outer edge of the elastic component I16 is fixed between the upper shell 1 and the lower shell 4, the upper floating valve 9 and the lower floating valve 11 will cause the elastic component I16 to deform until the upper floating valve 9 contacts the lower end of the suction stop nozzle 2. At this time, the limiting post 12 of the lower floating valve 11 will just hit the top limiting platform 20 of the upper shell 1 (e.g., Figure 11 (As shown).

[0087] In the second stage, water continues to be drawn upward through the outlet 5. The upper floating valve 9 continues to move upward and compress the suction stop nozzle 2, while the lower floating valve 11 is limited by the contact between the limiting post 12 and the top limiting platform 20, and no longer moves upward with the upper floating valve 9. The lower floating valve 11 gradually disengages from the upper floating valve 9, and the quantitative sealing component assembly begins to enter the separation state.

[0088] In the third stage, the negative pressure of upward water suction through outlet 5 continues. As the upper floating valve 9 continues to move upward until the suction nozzle 2 is compressed to its maximum extent, the upper floating valve 9 contacts the top limiting platform 20 and stops moving upward. At this point, the suction nozzle 2 is compressed to its maximum extent. In this stage, because the upper floating valve 9 separates from the lower floating valve 11, the suction force between suction component I14 and suction component II15 becomes ineffective due to the increased distance. It can no longer attract and adhere the upper floating valve 9 and the lower floating valve 11, and the second water passage 13 is no longer in contact with the upper floating valve 9. Water can flow freely from the second water passage 13 of the lower floating valve 11. The pressure on the upper and lower sides of the lower floating valve 11 is balanced, and it is no longer subjected to upward water pressure. Through the cooperation of the constraint structure 23 and the boss 17, the lower floating valve 11 is stabilized at the position where the boss 17 of the limiting post 12 contacts and is limited by the constraint structure 23 of the first water passage 10 (e.g., Figure 12 (As shown).

[0089] At this time, the suction at outlet 5 remains constant, and the upper floating valve 9 contacts and seals with the suction stop nozzle 2. Therefore, the pressure on the lower side of the upper floating valve 9 is higher than the pressure inside the suction stop nozzle 2, preventing the upper floating valve 9 from falling off and water from flowing into the suction stop nozzle 2. The maximum amount of water that can be drawn at this time is the water intake capacity of the metering suction device.

[0090] In the fourth stage, the suction at the outlet 5 is removed, and the negative pressure inside the suction nozzle 2 disappears instantly. At this time, water can flow freely from the first water passage 10 and the second water passage 13. The pressure on the upper and lower sides of the upper floating valve 9 is balanced. Under the force generated by the deformation of the elastic component I16, the upper floating valve 9 drives the lower floating valve 11 to move downward together. During the downward movement, the lower floating valve 11 will first contact the bottom limiting support structure 19 and be limited. At this time, the upper floating valve 9 continues to move downward until it returns to its original position and contacts the lower floating valve 11 to re-attract and adhere. The metering sealing component assembly returns to its combined state, and water cannot pass through the metering sealing component assembly. The metering sealing component assembly re-forms two mutually sealed cavities with the upper shell 1 and the lower shell 4.

[0091] Throughout the entire process from the first to the fourth stage, under the action of the one-way valve 3, the water can only flow into the device from the inlet 6 and cannot flow back, so the amount of water inside the metering water suction device will not decrease. At this time, the metered water (maximum suction capacity) is stored in the space between the upper shell 1 and the upper floating valve 9 for the next water suction action.

[0092] During normal water intake, water is drawn upwards through outlet 5. A fixed amount of water stored inside the upper shell 1 and above the upper floating valve 9 flows out through the suction nozzle 2 and outlet 5. Simultaneously, the pressure on the upper side of the upper floating valve 9 and lower floating valve 11 decreases, and the metering sealing component assembly is in the assembled state. The metering sealing component assembly moves upward, drawing external water back into the area below the metering sealing component assembly. This process is repeated from the initial water intake, thus achieving the goal of drawing a fixed amount of water from outlet 5 and storing it back inside the device (water intake) in a single water intake operation for the next cycle.

[0093] In this embodiment, the constant water volume of the device is the same as in Embodiment 1, and the calculation method is also the same.

[0094] A metered drinking cup includes a cup lid, a cup body, a straw 18, and a metered water intake device; the metered water intake device is installed between the cup lid and the cup body, the straw 18 is installed on the lower side of the water inlet 6 of the metered water intake device, the straw 18 is connected to a one-way valve 3, and the upper side of the water outlet 5 of the metered water intake device is sealed to the straw or the mouthpiece of the cup lid.

[0095] Furthermore, the connection methods between the water outlet 5 and the straw or cup lid include, but are not limited to, threaded, snap-fit, adhesive, insertion, silicone clamping, welding, interference fit and squeezing. In this embodiment 2, the connection method between the water outlet 5 and the straw or cup lid is a threaded connection, and the connection method between the water inlet 6 and the straw 18 is a squeezing connection.

[0096] Example 3

[0097] Reference Figure 3 and Figure 16 As shown, a quantitative water absorption device includes a housing, a suction nozzle 2, a quantitative sealing component assembly, and a one-way valve 3. The quantitative sealing component assembly is installed in the cavity of the housing and is sealed to the housing. The suction nozzle 2 is provided on the upper side of the quantitative sealing component assembly and is installed on the top of the housing. The upper end of the housing is provided with a water outlet 5, which communicates with the suction nozzle 2. The lower end of the housing is provided with a water inlet 6, and the one-way valve 3 is installed at the water inlet 6. When the quantitative sealing component assembly is in the assembled state, the quantitative sealing component assembly and the housing form two mutually sealed cavities, and water cannot flow from the quantitative sealing component assembly. When the quantitative sealing component assembly is in the separated state, water can flow freely between the quantitative sealing component assemblies.

[0098] Furthermore, the suction nozzle 2 is a structure that can extend and retract vertically and spring back. The suction nozzle 2 extends downward into the cavity of the housing and is preferably made of a corrugated tubular soft material.

[0099] Furthermore, the quantitative sealing component assembly includes an upper floating valve 9 and a lower floating valve 11. The upper floating valve 9 is provided with a suction component I14, and the lower floating valve 11 is provided with a suction component II15. The suction components I14 and II15 interact to generate an attractive force. When the quantitative sealing component assembly is in the assembled state, the attractive force of the suction components I14 and II15 causes the upper floating valve 9 and the lower floating valve 11 to attract and adhere to each other. When the quantitative sealing component assembly is in the separated state, the attractive force of the suction components I14 and II15 cannot maintain the mutual attraction and adhesion between the upper floating valve 9 and the lower floating valve 11.

[0100] The attraction components I14 and II15 can be coupled in ways including, but not limited to, magnetic attraction and attraction by materials with adsorption molecular properties. In this embodiment 3, the attraction component I14 is a magnet, and the attraction component II15 is an iron sheet. That is, the upper floating valve 9 contains a magnet, and the lower floating valve 11 contains an iron sheet.

[0101] Furthermore, the upper floating valve 9 is provided with a first water passage hole 10, which is located on the outside of the suction nozzle 2; the lower floating valve 11 is provided with a second water passage hole 13, which does not overlap with the first water passage hole 10; when the metering sealing component assembly is in the assembled state, the first water passage hole 10 is sealed to the upper surface of the lower floating valve 11, and the second water passage hole 13 is sealed to the lower surface of the upper floating valve 9, preventing water from flowing through the first water passage hole 10 and the second water passage hole 13; when the metering sealing component assembly is in the separated state, the first water passage hole 10 is separated from the upper surface of the lower floating valve 11, and the second water passage hole 13 is separated from the lower surface of the upper floating valve 9, allowing water to flow freely through the first water passage hole 10 and the second water passage hole 13.

[0102] Furthermore, the housing includes a column 21 and a top cover 22. The column 21 is an integrally formed structure and is a barrel-shaped structure with an open top. The top cover 22 is provided on the top of the column 21. The top cover 22 and the column 21 are sealed together. The suction nozzle 2 is installed at the lower end of the top cover 22. The upper end of the top cover 22 is provided with a water outlet 5, and the lower end of the column 21 is provided with a water inlet 6.

[0103] The connection between the upper cover 22 and the column 21 includes, but is not limited to, threaded connection, snap-fit ​​connection, bonding, insertion, silicone clamping, welding, interference fit and extrusion. In this embodiment 3, the upper cover 22 and the column 21 are connected by snap-fit ​​connection.

[0104] Furthermore, the lower floating valve 11 is also provided with a limiting post 12, which passes through the first water passage hole 10; the inner wall of the upper cover 22 is provided with a top limiting platform 20, which is located on the outside of the suction nozzle 2 and corresponds to the position of the limiting post 12; the distance between the upper floating valve 9 and the suction nozzle 2 is the same as the distance between the limiting post 12 and the top limiting platform 20.

[0105] In this embodiment 3, there are a total of 3 limiting posts 12, which are evenly distributed along the circumference of the lower floating valve 11.

[0106] Furthermore, the quantitative sealing component assembly also includes an elastic component I16, one end of which is connected to the upper floating valve 9 and the other end is fixed to the upper cover 22. The elastic component I16 connected to the outer side of the upper floating valve 9 is slidably and tightly sealed to the inner wall of the column 21.

[0107] Furthermore, the quantitative sealing component assembly also includes an elastic component II24, one end of which is connected to the lower floating valve 11 and the other end is fixed to the bottom of the column 21. The elastic component II24 connected to the outside of the lower floating valve 11 is slidably and tightly sealed to the inner wall of the column 21.

[0108] The elastic component I and elastic component II are provided with small holes to allow water to flow through.

[0109] The elastic components I16 and II24 are made of soft elastic material and have forms including, but not limited to, springs, cylindrical tubes, corrugated tubes, spiral tubes, and other stretchable and resilient structures. In this embodiment 3, the elastic components I16 and II24 are springs, or alternatively, corrugated tubes with holes in the sidewalls can be made of soft material.

[0110] Furthermore, a bottom limiting support structure 19 is provided at the bottom of the column 21. The bottom limiting support structure 19 contacts the lower end of the lower floating valve 11, and the bottom limiting support structure 19 limits the initial position of the lower floating valve 11.

[0111] The bottom limiting support structure 19 can be located inside the elastic member I16 or the elastic member II24, or it can be located outside the elastic member I16 or the elastic member II24.

[0112] The working process of the quantitative water absorption device in Example 3 is as follows:

[0113] During the initial water intake, in the first stage, when water is drawn upward through the outlet 5, the air in the upper part of the suction nozzle 2 and column 21 is drawn away, reducing the pressure on the upper floating valve 9 and lower floating valve 11. At this time, the metering sealing component assembly is in its initial assembled state, with the upper floating valve 9 and lower floating valve 11 tightly pressed together. The metering sealing component assembly, the upper cover 22, and the column 21 form two mutually sealed cavities. Due to the reduced pressure in the upper cavity, the upper floating valve 9 and lower floating valve 11 move upward together, thereby causing the water in the column 21 below the lower floating valve 11 to flow upward. As the pressure decreases, water from the outside of column 21 enters inlet 6 and flows through check valve 3 into the cavity between lower floating valve 11 and check valve 3 in column 21. At this time, upper floating valve 9 and lower floating valve 11 move upwards together under the action of water pressure and suction between suction components I14 and II15. Upper floating valve 9 compresses elastic component I16, and lower floating valve 11 stretches elastic component II24 until upper floating valve 9 contacts the lower end of suction nozzle 2. At this time, the limiting post 12 of lower floating valve 11 just touches the top limiting platform 20 (e.g., Figure 13 (As shown).

[0114] In the second stage, water continues to be drawn upward through outlet 5. The upper floating valve 9 continues to move upward and compress the suction nozzle 2, while the lower floating valve 11 is limited by the contact between the limiting post 12 and the top limiting platform 20, and no longer moves upward with the upper floating valve 9. The lower floating valve 11 gradually disengages from the upper floating valve 9, and the metering sealing component assembly enters a separated state (e.g., Figure 14 (As shown).

[0115] In the third stage, the negative pressure of upward water suction through outlet 5 continues. The upper floating valve 9 contacts the top limiting platform 20 and stops moving upward. At this time, the suction nozzle 2 is compressed to its maximum extent. In this stage, the second water passage 13 is no longer in contact with the upper floating valve 9, and water can flow freely from the second water passage 13 of the lower floating valve 11. The pressure on the upper and lower sides of the lower floating valve 11 is balanced, and it is no longer subjected to upward water pressure. Because the upper floating valve 9 and the lower floating valve 11 are separated, the suction between suction component I14 and suction component II15 becomes ineffective due to the increased distance, and can no longer attract the upper floating valve 9 and the lower floating valve 11 to stick together. At this time, the lower floating valve 11 moves downward under the force generated by the stretching of elastic component II24 until it returns to its original position. At this time, the suction at outlet 5 continues to exist, the upper floating valve 9 contacts and seals with the suction nozzle 2, so the pressure on the lower side of the upper floating valve 9 is higher than the pressure inside the suction nozzle 2, keeping the upper floating valve 9 from falling off, and water will not flow into the suction nozzle 2 (e.g., Figure 15 (As shown). The maximum amount of water that can be drawn at this time is the water absorption capacity of the metering water absorption device.

[0116] In the fourth stage, the suction at the outlet 5 is removed, and the negative pressure inside the suction nozzle 2 disappears instantly. At this time, water can flow freely from the first water passage 10. The pressure on the upper and lower sides of the upper floating valve 9 is balanced. Under the force generated by the compression of the elastic component I16, the upper floating valve 9 moves downward until it returns to its original position and contacts the lower floating valve 11 to re-attract and adhere. The metering sealing component assembly returns to its combined state, and water cannot pass through the metering sealing component assembly. The metering sealing component assembly, together with the upper cover 22 and the column 21, forms two mutually sealed cavities.

[0117] Throughout the entire process from the first to the fourth stage, under the action of the one-way valve 3, the water can only flow into the device from the inlet 6 and cannot flow back, so the amount of water inside the metering water suction device will not decrease. At this time, the metered water (maximum suction capacity) is stored in the space between the upper cover 22 and the upper floating valve 9 for the next water suction action.

[0118] During normal water intake, water is drawn upwards through outlet 5. A fixed amount of water stored in the space between the upper cover 22 and the upper floating valve 9 flows out through the suction nozzle 2 and outlet 5. At the same time, the upper pressure of the upper floating valve 9 and the lower floating valve 11 decreases, and the metering sealing component assembly is in the assembled state. The metering sealing component assembly moves upward, drawing water from outside the device back into the lower part of the metering sealing component assembly. This process is repeated from the first water intake operation, thus achieving the goal of drawing a fixed amount of water out of outlet 5 and storing a fixed amount of water back inside the device (water intake) in a single water intake operation for the next cycle.

[0119] The quantitative drinking water device in Example 3 can adjust the amount of water dispensed by adjusting the distance between the upper floating valve 9 and the suction nozzle 2, which is the distance between the limiting column 12 and the top limiting platform 20. The quantitative calculation method is as follows: the inner diameter of the column 21 is uniform from top to bottom as 'a', the distance from the upper floating valve 9 to the suction nozzle 2 (or the distance from the limiting column 12 to the top limiting platform 20) is 'b'. During the operation of the entire device from the first stage to the fourth stage, because the internal cross-section of the device is circular, the amount of water dispensed in a single operation is approximately equal to the volume of a cylinder with diameter 'a' and height 'b'. The calculation formula is: V = π(1 / 2a)b.

[0120] For example: if a=2cm and b=2cm, the single quantitative water output is approximately: π(1 / 2*2)*2≈6.28ml.

[0121] A metered drinking cup includes a cup lid, a cup body, a straw 18, and a metered water intake device; the metered water intake device is installed between the cup lid and the cup body, the straw 18 is installed on the lower side of the water inlet 6 of the metered water intake device, the straw 18 is connected to a one-way valve 3, and the upper side of the water outlet 5 of the metered water intake device is sealed to the straw or the mouthpiece of the cup lid.

[0122] Furthermore, the connection methods between the water outlet 5 and the straw or cup lid include, but are not limited to, threaded, snap-fit, adhesive, insertion, silicone clamping, welding, interference fit and compression. In this embodiment 3, the connection method is threaded, and the connection method between the water inlet 6 and the straw 18 is compression.

[0123] Example 4

[0124] like Figure 18 As shown, the difference between Embodiment 4 and Embodiment 3 is that one end of the elastic component I16 of the quantitative sealing component assembly is connected to the upper floating valve 9, and the other end is fixed to the bottom of the column 21; no elastic component II24 is provided. A constraint structure 23 is provided on the inner wall of the first water passage 10, and the limiting post 12 is adapted to the constraint structure 23. The limiting post 12 is slidably connected to the upper floating valve 9 through the constraint structure 23. The upper end of the limiting post 12 extends outward to form a boss 17, which contacts and limits the movement of the boss 17 with the upper surface of the constraint structure 23.

[0125] The difference between Example 4 and Example 3 lies in the working process:

[0126] When using it for the first time, in the first stage, the upper floating valve 9 and the lower floating valve 11 move upward together under the action of water pressure and the suction force between the suction component I14 and the suction component II15. The upper floating valve 9 will stretch the elastic component I16 until the upper floating valve 9 contacts the lower end of the suction stop nozzle 2.

[0127] In the third stage, water can flow freely from the second water passage 13 of the lower floating valve 11. The pressure on the upper and lower sides of the lower floating valve 11 is balanced, and it is no longer subject to upward water pressure. Through the cooperation of the constraint structure 23 and the boss 17, the lower floating valve 11 is stabilized at the position where the boss 17 of the limiting post 12 contacts and is limited by the constraint structure 23 of the first water passage 10.

[0128] In the fourth stage, the suction at the outlet 5 is removed, and the negative pressure inside the suction nozzle 2 disappears instantly. At this time, water can flow freely from the first water passage 10 and the second water passage 13. The pressure on the upper and lower sides of the upper floating valve 9 is balanced. Under the force generated by the deformation of the elastic component I16, the upper floating valve 9 drives the lower floating valve 11 to move downward together. During the downward movement, the lower floating valve 11 will first contact the bottom limiting support structure 19 and be limited. At this time, the upper floating valve 9 continues to move downward until it returns to its original position and contacts the lower floating valve 11 to re-attract and adhere. The metering sealing component assembly returns to its combined state, and water cannot pass through the metering sealing component assembly. The metering sealing component assembly re-forms two mutually sealed cavities with the upper shell 1 and the lower shell 4.

[0129] In this embodiment, the constant water volume of the device is the same as in Embodiment 3, and the calculation method is also the same.

[0130] Example 5

[0131] like Figure 19 As shown, the difference between Embodiment 5 and Embodiment 4 is that one end of the elastic component I16 of the quantitative sealing component assembly is connected to the upper floating valve 9, and the other end is fixed to the upper cover 22.

[0132] The difference between Example 5 and Example 4 is that during the upward movement of the floating valve 9, the elastic component I16 is in a compressed state.

[0133] Example 6

[0134] like Figure 20 As shown, the difference between Embodiment 6 and Embodiment 1 is that the upper floating valve 9 and the lower floating valve 11 provide attractive force through their own materials, without the installation of suction components I14 and II15. The lower floating valve 11 does not have a limiting post 12. The top inner wall of the upper shell 1 does not have a top limiting platform 20.

[0135] The difference between Example 6 and Example 1 lies in the working process:

[0136] In the first stage, the upper floating valve 9 and the lower floating valve 11 move upward together under the influence of water pressure and the attraction provided by their own materials. The movement of the upper floating valve 9 and the lower floating valve 11 causes the elastic component I16 and the elastic component II24 to deform until the upper floating valve 9 contacts the lower end of the suction nozzle 2.

[0137] In the second stage, water continues to be drawn upward through the outlet 5. The upper floating valve 9 continues to move upward and compress the suction nozzle 2. When the sum of the attraction between the lower floating valve 11 and the upper floating valve and the water pressure is less than the sum of the gravity of the lower floating valve 11 and the force of the elastic component II24, the lower floating valve 11 gradually disengages from the upper floating valve 9, and the quantitative sealing component assembly enters the separation state.

[0138] In the third stage, the negative pressure of water being drawn upward through the outlet 5 continues. When the upper floating valve 9 continues to move upward until the suction nozzle 2 is compressed to the maximum extent, the upper floating valve 9 contacts the top of the upper shell 1 and no longer moves upward. At this time, the suction nozzle 2 is compressed to the maximum extent.

[0139] Example 7

[0140] like Figure 2 As shown, the difference between Embodiment 7 and Embodiment 2 is that the upper floating valve 9 and the lower floating valve 11 provide attractive force through their own materials, and there are no suction components I14 and II15.

[0141] The difference between Example 7 and Example 2 lies in the working process:

[0142] In the first stage, the upper floating valve 9 and the lower floating valve 11 move upward together under the influence of water pressure and the attraction provided by their own materials.

[0143] In the third stage, because the upper floating valve 9 and the lower floating valve 11 are separated, the attraction force generated by their own materials becomes ineffective due to the increased distance, and the upper floating valve 9 and the lower floating valve 11 can no longer be attracted and attached together.

[0144] Example 8

[0145] like Figure 21 As shown, the difference between Embodiment 8 and Embodiment 3 is that the upper floating valve 9 and the lower floating valve 11 provide attractive force through their own materials, and there are no suction components I14 and II15. The lower floating valve 11 does not have a limiting post 12, and the top inner wall of the upper shell 1 does not have a top limiting platform 20.

[0146] The difference between Example 8 and Example 3 lies in the working process:

[0147] In the first stage, the upper floating valve 9 and the lower floating valve 11 move upward together under the influence of water pressure and the attraction provided by their own materials. The movement of the upper floating valve 9 and the lower floating valve 11 causes the elastic component I16 and the elastic component II24 to deform until the upper floating valve 9 contacts the lower end of the suction nozzle 2.

[0148] In the second stage, water continues to be drawn upward through the outlet 5. The upper floating valve 9 continues to move upward and compress the suction nozzle 2. When the sum of the attraction between the lower floating valve 11 and the upper floating valve 9 and the water pressure is less than the sum of the gravity of the lower floating valve 11 and the force of the elastic component II24, the lower floating valve 11 gradually disengages from the upper floating valve 9, and the quantitative sealing component assembly enters the separation state.

[0149] In the third stage, the negative pressure continues to draw water upward through the outlet 5, and the upper floating valve 9 stops moving upward when it contacts the top of the upper cover 22. At this time, the suction nozzle 2 is compressed to its maximum extent.

[0150] Example 9

[0151] like Figure 22 As shown, the difference between Embodiment 9 and Embodiment 4 is that the upper floating valve 9 and the lower floating valve 11 provide attractive force through their own materials, and there are no suction components I14 and II15.

[0152] The difference between Example 9 and Example 4 lies in the working process:

[0153] In the first stage, the upper floating valve 9 and the lower floating valve 11 move upward together under the influence of water pressure and the attraction provided by their own materials.

[0154] In the third stage, because the upper floating valve 9 and the lower floating valve 11 are separated, the attraction force generated by their own materials becomes ineffective due to the increased distance, and the upper floating valve 9 and the lower floating valve 11 can no longer be attracted and attached together.

[0155] Example 10

[0156] like Figure 23 As shown, the difference between Embodiment 10 and Embodiment 5 is that the upper floating valve 9 and the lower floating valve 11 provide attractive force through their own materials, and there are no suction components I14 and II15.

[0157] The difference between the working process of Example 10 and Example 5 is that:

[0158] In the first stage, the upper floating valve 9 and the lower floating valve 11 move upward together under the influence of water pressure and the attraction provided by their own materials.

[0159] In the third stage, because the upper floating valve 9 and the lower floating valve 11 are separated, the attraction force generated by their own materials becomes ineffective due to the increased distance, and the upper floating valve 9 and the lower floating valve 11 can no longer be attracted and attached together.
