Description

Technical Field

[0001] The utility model relates to the technical field of water supply control components matched with faucets, in particular to an automatic water stop valve. Background Art

[0002] The water stop valve is generally fixedly installed at the port of the faucet. It is often used to connect to the automatic washing machine with the cooperation of the quick-connect structure and the connecting hose, so that the faucet can remain in a normally open state, to cooperate with the solenoid valve installed on the automatic washing machine to realize the automatic cleaning function of the washing machine; when the quick-connect structure is disconnected, the water stop valve can automatically close the water channel to prevent the water from continuously overflowing. The principle is: when the water pressure in the water supply pipeline is too high and the quick-connect structure and the faucet are loose, the water stop valve can automatically seal the water outlet of the faucet under the action of water pressure, to prevent the water in the water supply pipeline from continuously leaking, thereby avoiding the occurrence of water accumulation in the house.

[0003] However, current water stop valves require a special quick-connect structure between them and the connecting hose. The end of this quick-connect structure must have a component that can support the water stop mechanism within the water stop valve to control the water flow. Without this structure, the connecting hose cannot directly connect to the water stop valve and trigger its water flow function. Furthermore, the quick-connect structure and connecting hose must remain connected to the water stop valve during use. If the quick-connect structure and connecting hose are removed to connect to other pipelines, the faucet must be turned off for disassembly and installation. Furthermore, most ordinary pipelines do not have a corresponding quick-connect structure, which severely limits the use of faucets equipped with water stop valves.

[0004] Moreover, although the public patent documents also involve solutions such as water stop valves and water stoppers with similar functions, such as the technical solution with patent number 202122668603.7 and patent name "An automatic water stop valve", the technical solution with patent number 202110630786.5 and patent name "An automatic water stopper", etc., they generally have the disadvantages of complex structure and cumbersome assembly of connecting hoses.

[0010] As a preferred technical solution, the outer diameter of the valve sleeve is smaller than the outer diameter of the bottom end of the quick-connect valve, and a protruding pipeline sleeve ring is provided on the outer wall of the valve sleeve. The outer diameter of the pipeline sleeve ring is smaller than or equal to the outer diameter of the bottom end of the quick-connect valve.

[0011] As an optimal technical solution, the quick-connect valve component includes a water-stop valve stem, the top end of the water-stop valve stem is connected to a water-stop valve plate, the water-stop valve plate protrudes from the peripheral side of the water-stop valve stem and is sealed and limited on the valve component limit platform, and a quick-connect sleeve is fixedly mounted on the outer periphery of the bottom end of the water-stop valve stem, and the water-passing gap is arranged between the water-stop valve plate and the valve component limit platform, and between the water-stop valve stem and the valve component sleeve.

[0012] As a preferred technical solution, the water through hole is provided on the water stop valve stem below the water through groove and is communicated with the water through groove or / and the water through hole passes through the quick-connect sleeve.

The valve component can be directly fitted and connected to the connecting hose. Since the outer diameter of the bottom end of the quick-connect valve component is large, it is equivalent to forming a structure for expanding the connecting hose outward, thereby improving the sleeve strength between the quick-connect valve component and the connecting hose, so that the connecting hose can continue to maintain a fixed connection with the quick-connect valve component, and play a role in preventing the connection from falling off; in the process of connecting the connecting hose, the quick-connect valve component will be pushed up, so that the connecting hose is connected to the faucet through the water channel and the water gap, and water can be transported outward; after the connecting hose is removed, the quick-connect valve component is pushed outward under the action of the water pressure in the water supply pipe, so that the channel between the connecting hose and the faucet is automatically closed, and the water in the water supply pipe is difficult to continue to flow out.

DETAILED DESCRIPTION

[0024] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0025] like Figures 1 to 5 As shown, an automatic water stop valve includes a fixed joint 1 for assembly with a faucet 5. A quick-connect valve member 2 is provided through the fixed joint 1, which can slide up and down. A water gap 3 is defined between the quick-connect valve member 2 and the fixed joint 1. When the quick-connect valve member 2 slides upward, the water gap 3 opens. When the quick-connect valve member 2 abuts against the fixed joint 1, the water gap 3 closes. The bottom end of the quick-connect valve member 2 extends outside the fixed joint 1. When connected to the pipes of a washing machine, the quick-connect valve member 2 is in an upward position, opening the water gap 3 and allowing water to flow from the faucet 5. When the pipes of the washing machine are separated from the faucet 5 by water pressure, the quick-connect valve member 2 slides down rapidly under the water pressure, closing the water gap 3 and cutting off the water flow, preventing continuous water outflow and ensuring safe water use. To ensure the stability and sealing of the connection between the fixed joint 1 and the faucet 5, commonly used pipe connection tools such as pipe clamps, raw tape, and sealing rings can be used.

[0026] The outer diameter of the bottom end of the fixed joint 1 is less than or equal to the outer diameter of the bottom end of the quick-connect valve 2. The fixed joint 1 includes a joint sleeve 11 for being fitted around the outer periphery of the port of the faucet 5. The bottom end of the joint sleeve 11 is fixedly connected to a valve sleeve 12. In fact, the outer diameter of the valve sleeve 12 is less than or equal to the outer diameter of the bottom end of the quick-connect valve 2. A valve stop 13 is formed inside the bottom end of the joint sleeve 11. The valve sleeve 12 and the joint sleeve 11 have different diameters, making the valve stop 13 a sealing connection platform between the two. After the quick-connect valve 2 is inserted from the upper end of the joint sleeve 11, its top end, i.e., a sealing stop, is located on the valve stop 13.

[0027] In this embodiment, a water passage is provided through the bottom end of the quick-connect valve member 2. When the connecting hose 6 is connected to the fixed joint 1 and the quick-connect valve member 2, the faucet 5 and the connecting hose 6 communicate through the water gap 3 and the water passage, and water is delivered outward. When the connecting hose 6 falls off under the action of water pressure, the water pressure within the faucet 5 presses the quick-connect valve member 2 downward, eliminating the gap between the quick-connect valve member 2 and the valve member stop 13, blocking the communication channel between the faucet 5 and the connecting hose 6, and making it difficult for water to flow out through the water gap 3 and the water passage, thereby achieving a water-stopping effect.

[0028] The quick-connect valve member 2 is provided with an axially arranged, top-enclosed water channel 26. A valve member through-hole 27 is provided along the circumference of the quick-connect valve member 2, connecting the water gap 3 with the water channel 26. The water channel comprises a water channel recessed around the bottom end of the quick-connect valve member 2 and / or a water channel through-hole 4 extending through the bottom end of the quick-connect valve member 2. When the quick-connect valve member 2 is connected to the connecting hose 6, the water gap 3, the water channel 26, and the valve member through-hole 27 communicate with the connecting hose 6 via the water channel recessed and / or the water channel through-hole 4.

[0029] The quick-connect valve assembly 2 includes a water-stop valve stem 21, the top end of which is connected to a water-stop valve plate 22. The water-stop valve plate 22 protrudes from the circumference of the water-stop valve stem 21 and is sealed against the valve member stop platform 13. A quick-connect sleeve 23 is fixedly mounted on the outer periphery of the bottom end of the water-stop valve stem 21. The water-flow gap 3 is arranged between the water-stop valve plate 22 and the valve member stop platform 13, and between the water-stop valve stem 21 and the valve member sleeve 12. The quick-connect sleeve 23 is used for assembly with the connecting hose 6, so the outer diameter of the valve member sleeve 12 is less than or equal to the outer diameter of the quick-connect sleeve 23.

[0030] Specifically, the water-passing hole 4 is provided on the water-stop valve stem 21 below the water-passing groove 26 and is in communication with the water-passing groove 26 or / and the water-passing hole 4 is provided through the quick-connect sleeve 23. That is, the water-passing recess and the water-passing hole 4 can be provided separately or simultaneously (the water-passing recess is not shown in the figure of this embodiment), and multiple water-passing holes 4 can be provided, and the outline can be circular, elliptical, etc. The water-passing recess is provided on the circumference of the quick-connect sleeve 23. When the water-passing recess is provided on the quick-connect sleeve 23, the outer outline of the quick-connect sleeve 23 is no longer a standard circular structure.

[0031] The outer wall of the water stop valve plate 22 is provided with a protruding sealing ring 24, and the bottom surface of the sealing ring 24 is flush with the bottom surface of the water stop valve plate 22, which helps to improve the sealing performance of the water stop valve when stopping water. Alternatively, a dedicated sealing ring can be provided on the valve member limit platform 13, and the water stop valve plate 22 and the sealing ring 24 can be pressed together to achieve a more effective seal.

[0032] When the quick-connect valve 2 is fitted over the connecting hose 6, the inner wall of the connecting hose 6 seals against the outer wall of the quick-connect sleeve 23, while the inner wall of the upper end of the connecting hose 6 seals against the outer wall of the valve sleeve 12, thereby establishing a sealed water supply connection. A sleeve folded edge 25 is provided at the top of the quick-connect sleeve 23 to increase the contact surface between the quick-connect sleeve 23 and the connecting hose 6, thereby enhancing the secure connection between the two.

[0033] When the outer diameter of the valve sleeve 12 is smaller than the outer diameter of the bottom end of the quick-connect valve 2 (i.e., smaller than the outer diameter of the quick-connect sleeve 23), a protruding pipe sleeve ring 14 can be provided on the outer wall of the valve sleeve 12. In this case, the outer diameter of the pipe sleeve ring 14 is equal to or smaller than the outer diameter of the bottom end of the quick-connect valve 2 (i.e., smaller than the outer diameter of the quick-connect sleeve 23). When assembled with the connecting hose 6, the inner wall of the connecting hose 6 also seals against the outer wall of the pipe sleeve ring 14.

[0034] The pipe sleeve ring 14 is provided to facilitate mating with a connecting hose 6 having a quick-connect structure, such as the connecting hose 6 on an automatic washing machine, where the quick-connect structure at the end can be directly snap-fitted and fixed to the pipe sleeve ring 14. Thus, this embodiment can be mated with both connecting hoses 6 with quick-connect structures and those without quick-connect structures, thereby increasing flexibility and reducing restrictions on the use of the water stop valve.

[0035] When this embodiment is used in conjunction with the connecting hose 6 without a quick-connect structure, Figure 4As shown, since the outer diameter of the quick-connect sleeve 23 is relatively large, it is equivalent to forming a structure for expanding the connecting hose 6 outward. Under the elastic deformation of the connecting hose 6, the connection between the two is made tighter and stronger, thereby playing a role in preventing the connection from falling off. The outer diameter of the pipe sleeve ring 14 is also larger than the inner diameter of the connecting hose 6, which can also make the connecting hose 6 firmly sleeved on the pipe sleeve ring 14. In the state of connection with the connecting hose 6, the water stop valve stem 21, the water stop valve plate 22, and the sealing ring edge 24 are moved upward synchronously, so that the water gap 3, the valve through hole 27, the water groove 26, the water through hole 4, etc. can be connected to the connecting hose 6, realizing the outward transportation of water in the water supply pipe; after use, as shown Figure 5 As shown, when the connecting hose 6 is removed or falls off by itself, the water pressure in the water supply pipe causes the water stop valve stem 21, the water stop valve plate 22, and the sealing ring edge 24 to move downward synchronously, the water gap 3 is closed, and the water supply passage is no longer connected, thereby achieving the water stop function.

[0036] This embodiment eliminates the need for the water stop valve to be constantly connected to the quick-connect structure and the connecting hose 6. Instead, the valve can be detached and used directly with other connecting hoses 6 without quick-connect structures, depending on the intended use. For example, it can be used to connect water pumps, gardening equipment, and other products. This allows for simple operation and quick connection. Even if the connecting hose 6 becomes detached during use, the water stop valve plate 22 and the sealing ring 24 quickly close the water gap 3 under the action of water pressure, thereby cutting off the water supply path and avoiding water waste.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
