Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water valves, in particular to a water valve connected with a water inlet pipe joint of a washing machine. BACKGROUND

[0002] Before use, the washing machine needs to be connected with the water valve through the water inlet pipe joint. The water inlet structure of the washing machine is basically a unified structure design, and the structure of the water inlet pipe joint is also specific. Therefore, in order to connect the water inlet of the washing machine with the water outlet of the water valve, the structure of the water outlet of the water valve needs to be adapted to the structure of the water inlet pipe joint.

[0003] The specific water inlet pipe joint includes a steel head, four screws, a plastic joint nut and a gasket. The four screws are arranged circumferentially and screwed with the steel head. The gasket is placed in the plastic joint nut. The plastic joint nut is screwed with the steel head. When the water inlet pipe joint is installed to the water outlet of the water valve, the four screws on the steel head are loosened first. The steel head is sleeved on the water outlet of the water valve. The gasket in the plastic joint abuts against the bottom of the water outlet of the water valve. Then the four screws are tightened with a screwdriver to press the ends of the four screws against the outer surface of the water valve to fix the steel head. Then the plastic joint is screwed to press the gasket against the bottom of the water outlet of the water valve until no water leaks. The bottom of the plastic joint nut is provided with a plug-in pipe for sealing and plugging with the water inlet of the washing machine. The plug-in pipe is inserted into the water inlet of the washing machine. The water inlet of the washing machine is provided with a buckle. The buckle is buckled on the plastic joint nut. The final installation of the water inlet of the washing machine and the water valve is completed.

[0004] However, in actual use, the water valve is usually open regardless of whether the washing machine is used or not for the sake of convenience. Since the water inlet pipe joint is only fixed with the water valve by pressing the four screws, the water pressure will impact the water pipe when the water flows through the water pipe of the washing machine. Under the impact of water pressure, the four screws are prone to loosen after a long period of use, causing the water inlet pipe joint to separate from the water valve. Since the water valve is in an open state, water will flow directly to the ground after the water inlet pipe joint separates, resulting in a room full of water. SUMMARY

[0005] The purpose of the present application is to provide a water valve connected with a water inlet pipe joint of a washing machine to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme: a water valve connected with a water inlet pipe joint of a washing machine, comprising a housing provided with a water outlet and a water inlet, further comprising:

[0010] When the water inlet connector is separated from the water outlet, under the action of gravity, the movable core slides downward to the limit position to make the blocking member enter the closed state.

[0012] The water valve connected with the water inlet connector of the washing machine, the top opening of the circular tube is larger than the bottom opening, the blocking member is located in the circular tube, and the outer surface of the blocking member is sealingly attached to the inner wall of the circular tube.

[0013] The water valve connected with the water inlet connector of the washing machine, the blocking member comprises a circular pad, the outer surface of the circular pad is sealingly attached to the inner wall of the circular tube so that the circular pad cannot move downward, a water passage is formed in the circular pad, a sealing plate for blocking the water passage is rotatably arranged on the circular pad, the sealing plate abuts against the movable core, when the movable core is pushed upward by the gasket, the movable core pushes the sealing plate upward to open the water passage, and when the movable core slides downward to the limit position, the movable core pulls the sealing plate downward to block the water passage.

[0014] The water valve connected with the water inlet connector of the washing machine, the movable core comprises a cylinder slidingly inserted into the water outlet tube, the top of the cylinder is fixedly connected with a top plate corresponding to the sealing plate, the sealing plate abuts against the top plate, when the water inlet connector is mounted to the water outlet, the top plate pushes the sealing plate to rotate upward to open the water passage.

[0015] The water valve connected with the water inlet connector of the washing machine, the front side of the top plate abuts against the front side inner wall of the water passage, and the rear side of the top plate abuts against the rear side inner wall of the water passage.

[0016] The water valve connected with the water inlet pipe joint of the washing machine, the number of the sealing plates and the top plates is two, the two top plates are located between the two sealing plates, the top of the two top plates and the top of the two sealing plates are inclined to the inside, the free ends of the two sealing plates are respectively and correspondingly slidably abut on the outer sides of the two top plates, the top plates have elasticity, and when the water pressure increases, the two sealing plates are driven to rotate to the inside to press the two top plates to move close to the inside and reduce the distance between the top of the two top plates.

Whether the sealing piece is opened or closed is determined by whether the water inlet pipe joint is connected to the water outlet. When the water inlet pipe joint is normally connected to the water outlet, the gasket in the water inlet pipe joint pushes up the movable core to make the sealing piece enter the open state. When the water inlet pipe joint is separated from the water outlet, the movable core loses the support of the gasket, and thus slides down and drives the sealing piece to enter the closed state, so that the water inlet and the water outlet of the shell are not communicated, so that water cannot flow out of the water valve, and thus the phenomenon of water accumulation in the house cannot be caused. Compared with the prior art, the water valve provided by the application can be automatically closed when the water inlet pipe joint is separated from the water outlet, so that even if the water valve is always in the open state, water will not flow to the ground when the water inlet pipe joint is separated from the water outlet, and water accumulation in the house will not occur. The deficiencies in the prior art can be effectively solved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical scheme of the embodiments of the present application or the prior art clearer, the accompanying drawings needed in the embodiments will be briefly introduced. Obviously, the accompanying drawings in the following description only need to explain some embodiments of the present application, and other drawings can be obtained by those skilled in the art based on these drawings.

[0032] As Figures 1-7As shown, the water valve for connecting with the water inlet pipe joint of the washing machine provided by the embodiment of the present application comprises a shell 1 provided with a water outlet and a water inlet, and further comprises:

[0033] a plugging member which is sealingly arranged in the shell 1, located between the water outlet and the water inlet, and has an open state and a closed state;

[0034] a movable core which is slidingly arranged in the shell 1 and cooperates with the plugging member;

[0035] When the water inlet pipe joint is mounted on the water outlet, the gasket 10 in the water inlet pipe joint pushes up the movable core to make the plugging member enter the open state;

[0036] When the water inlet pipe joint is separated from the water outlet, the movable core slides down to the limit position under the action of gravity to make the plugging member enter the closed state.

[0037] The water valve provided in this embodiment connects to the washing machine's water inlet pipe connector. One end connects to a tap water pipe, and the other end connects to one end of the water inlet pipe connector. The other end of the water inlet pipe connector connects to the washing machine's water inlet, thus ultimately connecting the washing machine's water inlet to the tap water pipe. In this embodiment, terms related to direction and position, such as "up," "down," "left," and "right," are relative to the accompanying drawings. Specifically, the housing 1 has a sealed inner cavity. The water outlet and water inlet are connected to the inner cavity of the housing 1. The water inlet is used to connect to the tap water pipe to allow water to enter the inner cavity of the housing 1, and the water outlet is used to connect to the water inlet pipe connector to allow water to enter the washing machine's water inlet through the water inlet pipe connector. The sealing element is installed in the inner cavity of the housing 1 and is located between the water outlet and the water inlet, so that the water outlet and the water inlet are sealed and separated by the sealing element. Whether the water outlet and the water inlet are connected depends on whether the sealing element is open. When the sealing element is in the open state, the water outlet and the water inlet are connected. At this time, the water valve is open, and the water source in the tap water pipe can enter the water inlet of the washing machine through the water valve. When the sealing element is in the closed state, the water outlet and the water inlet are not connected. At this time, the water valve is closed, and the water source in the tap water pipe cannot be discharged from the water valve. The opening and closing of the sealing element is determined by the position of the movable core. The movable core is slidably disposed in the inner cavity of the housing 1 and cooperates with the sealing element. The movable core slides into the inner cavity of the housing 1 from the water outlet. In the initial state, under the action of its own weight, the bottom of the movable core protrudes from the water outlet. When the water inlet pipe connector is installed on the water outlet, the washer 10 in the water inlet pipe connector abuts against the bottom of the movable core and pushes the movable core upward, causing the movable core to rise. During the upward movement of the movable core, it applies force to the sealing element, thereby causing the sealing element to move from the closed state to the open state. As long as the water inlet pipe connector is in the correct position... When the valve is connected to the outlet, the sealing element is in the open position, meaning the water valve is open. After prolonged use, under the impact of water pressure, the inlet pipe connector may detach from the outlet. Once the inlet pipe connector detaches from the outlet, the movable core slides rapidly downwards under its own weight and the impact of water pressure, causing the force exerted by the movable core on the sealing element to disappear instantly. As the movable core slides downwards, the sealing element gradually enters the closed position. When the movable core slides down to its limit position, the sealing element completely closes. The entire process is completed quickly to prevent tap water from flowing out of the water valve. In existing technology, for convenience, the water valve is usually left open regardless of whether the washing machine is in use. Since the water inlet pipe connector is only fixed to the water valve by the compression of four screws, the water pressure when the water flows through the washing machine's water pipe will impact the water pipe. Under the impact of water pressure, after a long period of use, the four screws can easily loosen, causing the water inlet pipe connector to detach from the water valve. Since the water valve is in the open state, the water will flow directly to the ground after the water inlet pipe connector detaches, resulting in water accumulation in the room.

[0038] The water valve for connecting with the water inlet pipe joint of the washing machine provided by the embodiment is characterized in that a sealing plug and a movable core are arranged in the shell 1 to enable the movable core to control the opening and closing of the sealing plug, the sealing plug is arranged in the shell 1 and located between the water outlet and the water inlet, the water inlet and the water outlet of the shell 1 are in communication when the sealing plug is in the open state, the water inlet and the water outlet of the shell 1 are not in communication when the sealing plug is in the closed state, and the opening and closing of the sealing plug are determined by whether the water inlet pipe joint is connected to the water outlet, the gasket 10 in the water inlet pipe joint pushes the movable core upward to enable the sealing plug to be in the open state when the water inlet pipe joint is normally connected to the water outlet, the movable core loses the support of the gasket 10 when the water inlet pipe joint is separated from the water outlet, thereby sliding downward and driving the sealing plug to be in the closed state, so that the water inlet and the water outlet of the shell 1 are not in communication, water cannot flow out of the water valve, and the phenomenon of water accumulation in the house cannot occur. Compared with the prior art, the water valve can be automatically closed when the water inlet pipe joint is separated from the water outlet, so that even if the water valve is always in the open state, water cannot flow to the ground when the water inlet pipe joint is separated from the water outlet, and water accumulation in the house cannot occur, and the deficiencies in the prior art can be effectively solved.

[0039] The water inlet pipe joint is a specific structure in the prior art, that is, the water inlet pipe joint comprises a steel head 7, four screws 8, a plastic joint nut 9 and a gasket 10, the four screws 8 are arranged in the circumferential direction and are screwed with the steel head 8, the gasket 10 is arranged in the plastic joint nut 9, the outer surface of the gasket 10 is attached to the inner wall of the plastic joint nut 9, the center of the gasket 10 is hollow to enable water to flow through, the outer surface of the steel head 7 is provided with external threads, and the plastic joint nut 9 is threadedly connected to the outside of the steel head 7. In the embodiment, when the water inlet pipe joint is installed to the water outlet, the top of the steel head 7 is first aligned with the bottom of the movable core, and the water inlet pipe joint is moved upward, so that the bottom of the movable core is inserted into the plastic joint nut 9 and abuts against the top of the gasket 10, the gasket 10 continuously pushes the movable core upward as the water inlet pipe joint is continuously moved upward, the upward movement of the movable core drives the sealing plug to be opened, and the upward movement of the water inlet pipe joint is stopped when the top of the gasket 10 abuts against the bottom of the water outlet, at this time, the bottom of the movable core is level with the bottom of the water outlet, then the four screws 8 are fastened with a screwdriver, so that the ends of the four screws 8 press the outer surface of the water valve to fix the steel head 7, and then the plastic joint nut 9 is screwed to press the gasket 10 against the bottom of the water outlet, and the screwing of the plastic joint nut 9 is stopped, the bottom of the plastic joint nut 9 is integrally provided with a plug-in pipe 901 which is sealingly plugged with the water inlet of the washing machine, the plug-in pipe 901 is in communication with the water outlet, the plug-in pipe 901 is inserted into the water inlet of the washing machine, the water inlet of the washing machine is provided with a buckle which is buckled on the plastic joint nut 9, and the final installation of the water inlet of the washing machine and the water valve is completed.

[0040] In the embodiment, the shell 1 comprises a cylindrical tube 101, a circular truncated cone tube 102 and a water outlet tube 103 arranged in sequence from top to bottom, the top of the cylindrical tube 101 is sealed, the cylindrical tube 101, the circular truncated cone tube 102 and the water outlet tube 103 are sealed, a water inlet tube 105 is fixed on the cylindrical tube 101, the outer port of the water inlet tube 105 is a water inlet, the outer surface of the water inlet tube 105 is provided with external threads, the water inlet tube 105 is threadedly connected with the water outlet of a tap, the outer port of the water outlet tube 103 is a water outlet, when the water inlet tube joint is installed, the steel head 7 is sleeved on the water outlet tube 103, and the end portions of the four screws 8 abut against and are pressed against the outer surface of the water outlet tube 103.

[0041] In the embodiment, the top opening of the circular truncated cone tube 102 is larger than the bottom opening, the sealing member is located in the circular truncated cone tube 102, the outer surface of the sealing member is sealingly and closely fitted with the inner wall of the circular truncated cone tube 102, and the circular truncated cone design of the circular truncated cone tube 102 enables the sealing member to be limited in the circular truncated cone tube 102 and not to move downward, so that the sealing effect of the sealing member is achieved.

[0042] The sealing member comprises a circular truncated cone-shaped sealing gasket 6, the shape of the sealing gasket 6 is matched with the circular truncated cone tube 102, the sealing gasket 6 is a rubber gasket, the outer surface of the sealing gasket 6 is sealingly and closely fitted with the inner wall of the circular truncated cone tube 102 so that the sealing gasket 6 cannot move downward, a water passing hole 602 is formed in the sealing gasket 6, a sealing plate 5 for sealing the water passing hole 602 is rotatably arranged on the sealing gasket 6 through a rotating shaft 501, the sealing plate 5 can rotate upward and downward, the water passing hole 602 is closed when the sealing plate 5 rotates downward to the limit position, the water passing hole 602 is opened as soon as the sealing plate 5 rotates upward, the closing and opening of the sealing member are realized by the closing and opening of the water passing hole 602, the sealing plate 5 abuts against the movable core, and the movable core pushes the sealing plate 5 upward to open the water passing hole 602 when the movable core is lifted by the gasket 10, and the movable core pulls the sealing plate 5 downward to seal the water passing hole 602 when the movable core slides to the limit position, so that the opening and closing of the water passing hole 602 are realized.

[0043] The top of the sealing gasket 6 is provided with a groove 601, the groove 601 is located above and communicates with the water passing hole 602, the rotating shaft 501 is inserted into the groove 601, the rotating shaft 501 is rotatably inserted with the sealing plate 5, so that the sealing plate 5 is located above the water passing hole 602, when the sealing plate 5 rotates downward to the limit state, the bottom surface of the sealing plate 5 closely fits with the bottom surface of the groove 601 and covers the water passing hole 602, so that the sealing plate 5 seals the water passing hole 602, and the water passing hole 602 is closed.

[0044] In the embodiment, the movable core comprises a cylinder 3 slidingly inserted into the outlet pipe 103, the outer surface of the cylinder 3 is attached to the inner wall of the outlet pipe 103, the top of the cylinder 3 is fixedly connected with a top plate 4 corresponding to the sealing plate 5, the top plate 4 passes through the water passage hole 602, the sealing plate 5 abuts against the top plate 4, when the inlet pipe joint is installed on the water outlet, the top plate 4 pushes the sealing plate 5 to rotate upward to open the water passage hole 602, when the inlet pipe joint is separated from the outlet pipe 103, the support force of the gasket 10 on the bottom of the movable core disappears, so that the movable core slides downward, the sliding of the movable core makes the top plate 4 slide downward, the movable core no longer supports the sealing plate 5, under the action of the downward pulling force of the top plate 4, the sealing plate 5 rotates downward to the limit state to block the water passage hole 602.

[0045] Further, the top view of the water passage hole 602 is square, the front side and the rear side of the top plate 4 and the front inner wall and the rear inner wall of the water passage hole 602 are parallel to each other, the front side of the top plate 4 abuts against the front inner wall of the water passage hole 602, and the rear side of the top plate 4 abuts against the rear inner wall of the water passage hole 602, so that the top plate 4 is limited by the water passage hole 602, the top plate 4 cannot rotate, and the movable core cannot rotate, so as to improve the stability of the movable core in use, and the movable core cannot rotate in the process of rotating the plastic joint nut 9 to drive the gasket 10 to rotate, so that the top plate 4 remains in abutment with the sealing plate 5, and the upward and downward movement of the top plate 4 can control the upward and downward rotation of the sealing plate 5, so as to realize the opening and closing of the water passage hole 602.

[0046] Further, the number of the sealing plates 5 and the top plates 4 is two, the two top plates 4 are located between the two sealing plates 5, the top of the two top plates 4 and the top of the two sealing plates 5 are inclined to the inside (the inside refers to the direction of approaching each other), the free end of the two sealing plates 5 respectively and correspondingly slide and abut on the outer side of the two top plates 4, the water source flows into the casing 1 from the water inlet and then flows into the two top plates 4 from the top of the two top plates 4, and then sequentially passes through the groove 601, the water hole 602 and the cylinder 3 to enter the water outlet, when the distance between the top of the two top plates 4 changes, the water flow flowing into the water outlet can be changed, and then the impact force of the water flow on the washing machine water pipe can be changed, when the distance between the top of the two top plates 4 decreases, the water flow flowing into the water outlet can be reduced, and then the impact force of the water flow on the washing machine water pipe can be reduced, and vice versa, the top plate 4 has elasticity, that is, when the water pressure in the casing 1 increases, the two sealing plates 5 are driven to rotate to the inside to press the two top plates 4 to approach each other to reduce the distance between the top of the two top plates 4, so as to reduce the water flow flowing into the water outlet, and then reduce the impact force of the water flow on the washing machine water pipe, so that the water inlet connector is not easy to separate from the water outlet. In the prior art, when the water pressure in the water pipe increases, the water pressure in the casing 1 increases, and the increase of the water pressure in the casing 1 undoubtedly increases the water flow flowing into the water outlet, and then increases the impact force of the water flow on the washing machine water pipe, so that the water inlet connector is more likely to separate from the water outlet. And the activity core of the application is designed by the key, so that the activity core also plays a role in automatically adjusting the size of the water flow flowing into the water outlet according to the size of the water pressure in the casing 1, when the water pressure in the casing 1 increases, the distance between the top of the two top plates 4 can be automatically reduced, so as to reduce the water flow flowing into the water outlet, and then reduce the impact force of the water flow on the washing machine water pipe, and then make the water inlet connector not easy to separate from the water outlet.

[0047] Specifically, because the top of the two sealing plates 5 is inclined to the inside, the two sealing plates 5 can respectively generate an inward pressing force on the two top plates 4, and the size of the pressing force of the sealing plate 5 on the top plate 4 depends on the size of the impact force of the water pressure on the top surface of the two sealing plates 5, when the water pressure increases, the pressure on the top surface of the two sealing plates 5 increases, so that the pressing force of the two sealing plates 5 on the two top plates 4 increases, the top plate 4 has elasticity, so that the top of the two top plates 4 approaches each other, so that the distance between the top of the two top plates 4 decreases, and then the water amount flowing into the two top plates 4 decreases, and then the water amount flowing into the water outlet decreases, and finally the impact force of the water flow on the washing machine water pipe is reduced.

[0048] In the initial state, the outer sides of the two top plates 4 abut against the left and right inner walls of the water passage hole 602, and at the same time, the front side of the top plate 4 abuts against the front inner wall of the water passage hole 602, and the rear side of the top plate 4 abuts against the rear inner wall of the water passage hole 602, so that the water flow cannot flow into the water outlet from the outer sides of the two top plates 4, but only from the space between the two top plates 4; when the two top plates 4 are inclined inward, although a gap is formed between the outer sides of the two top plates 4 and the left and right inner walls of the water passage hole 602, the width of the gap is smaller than the reduced distance between the top portions of the two top plates 4 (which is common knowledge), so that the amount of water flowing into the water outlet is still reduced, thereby reducing the amount of water entering the water outlet, and finally reducing the impact of the water flow on the water pipe of the washing machine. Of course, when the two top plates 4 are inclined inward, in order to improve the reduction of the amount of water entering the water outlet, thereby improving the effect of reducing the impact of the water flow on the water pipe of the washing machine, the left and right sides of the water passage hole 602 can be provided with sliding plates (not shown in the figure) that are elastically and slidingly connected to the sealing gasket 6. The sliding plates are elastically biased inward, so that the opposite ends of the two sliding plates abut against the outer sides of the two top plates 4, respectively. The elastic force of the sliding plates is provided by a spring (not shown in the figure). When the two top plates 4 are inclined inward, the two sliding plates will slide towards the two top plates 4 under the action of the elastic force, so that the two sliding plates always abut against the two top plates 4, thereby preventing the water flow from flowing into the water outlet from the outer sides of the two top plates 4, and the water flow can only flow into the water outlet from the space between the two top plates 4. When the distance between the top portions of the two top plates 4 is reduced, the amount of water flowing into the water outlet will be significantly reduced, thereby significantly reducing the impact of the water flow on the water pipe of the washing machine.

[0049] At the same time, the inclination of the top portions of the two sealing plates 5 inward also has another effect: the center of gravity of the two sealing plates 5 is biased inward. When the water inlet connector is separated from the water outlet pipe 103, since the top plate 4 no longer supports the sealing plate 5, at this time the two sealing plates 5 can be rotated downward under the action of their own gravity to block the water passage hole 602, thereby improving the speed of the sealing plate 5 in blocking the water passage hole 602. At the same time, the top surface of the sealing plate 5 will be impacted by the water pressure, so that the sealing plate 5 rotates downward at a faster speed. The rapid downward rotation of the sealing plate 5 not only further improves the speed of blocking the water passage hole 602, but also presses the top plate 4 downward to make the movable core quickly slide to the limit state, thereby improving the response speed of the water valve. When the water inlet connector is separated from the water outlet pipe 103, the water valve can be quickly closed, thereby greatly reducing the amount of water flow to the ground.

[0050] In the embodiment, the top plate 4 comprises the elastic sheets 401 and the plane plates 402 fixedly connected from bottom to top, the elastic sheets 401 are fixedly connected with the cylinder 3, the thickness of the elastic sheets 401 is towards left and right, the width is towards front and back, so that the elastic sheets 401 can be bent and deformed in left and right directions, the plane plates 402 slide through the water passing holes 602. The elastic force of the two elastic sheets 401 is towards the outside, the free ends of the two sealing plates 5 respectively slide and abut against the outer sides of the two plane plates 402, under the elastic force of the two elastic sheets 401, the two plane plates 402 respectively provide support for the two sealing plates 5, so that the two sealing plates 5 can be in the open state. When the water pressure in the shell 1 increases, the degree of the two sealing plates 5 pressing the two plane plates 402 increases, the two plane plates 402 drive the two elastic sheets 401 to further deform towards the inside, so as to realize that the distance between the top parts of the two plane plates 402 decreases, and vice versa, which is not described in detail.

[0051] Further, the top parts of the plane plates 402 are integrally connected with the outer bending plates 403, the outer bending plates 403 are overlapped with the free ends of the sealing plates 5 in the process of the movable core sliding downwards, so that the movable core will not slide out of the shell 1, and the movable core will not fall to the ground, thereby playing a protection role on the movable core; at the same time, when the outer bending plates 403 are overlapped with the free ends of the sealing plates 5, the contact positions of the sealing plates 5 and the plane plates 402 are farther away from the elastic sheets 401, by using the principle of fulcrum, the two sealing plates 5 can more forcefully push the two plane plates 402 towards the inside under the condition that the water pressure in the shell 1 is unchanged, and the gravity of the movable core will generate a downward pulling force on the two sealing plates 5 when the outer bending plates 403 are overlapped with the free ends of the sealing plates 5, further increasing the degree of the two sealing plates 5 pushing the two plane plates 402 towards the inside, so as to ensure that the two plane plates 402 can abut against each other at the top parts of the two plane plates 402 under the pushing action of the two sealing plates 5 when the movable core slides to the limit state (as shown in FIG. 10), so as to make the water valve close, at this time, the water flow still cannot flow into the water outlet.

[0052] In the embodiment, the cylindrical pipe 101 comprises the upper half pipe 1011 and the lower half pipe 1012 screwed, so that the cylindrical pipe 101 can be disassembled, thereby facilitating the sealing member to be put into the shell 1, so as to realize the installation and disassembly work of the sealing member.

[0053] ​In the embodiment, the cylindrical pipe 101 is further fixed with an internally threaded pipe 104, which is coaxially arranged with the water inlet pipe 105, and the internally threaded pipe 104 is logically provided with a sealing mechanism 2 for sealing the water inlet pipe 5. Rotating the sealing mechanism 2 can seal the port of the water inlet pipe 5 by the sealing mechanism 2, so as to close the water valve. When the water inlet pipe joint is installed and disassembled, the water valve can be closed by rotating the sealing mechanism 2 first, so as to prevent the water valve from spraying when the water inlet pipe joint is installed and disassembled.

[0054] The sealing mechanism 2 includes a threaded rod 201 which is screwed into the internally threaded pipe 104, one end of the threaded rod 201 is located in the housing 1 and fixedly installed with a sealing plug 202, the other end of the threaded rod 201 is located outside the housing 1 and fixedly installed with a handle 203, the sealing plug 202 is in the shape of a circular truncated cone, the diameter of the side of the sealing plug 202 facing the water inlet pipe 105 is less than the inner diameter of the water inlet pipe 105, and the diameter of the side of the sealing plug 202 away from the water inlet pipe 105 is greater than the inner diameter of the water inlet pipe 105. By rotating the handle 203 to drive the threaded rod 201 to rotate, the sealing plug 202 is inserted into the water inlet pipe 105 to seal the water inlet pipe 105, so as to close the water valve. When the handle 203 is reversely rotated, the sealing plug 202 is moved out of the water inlet pipe 105 to make the water inlet pipe conductive, so as to open the water valve.

[0055] The above only describes some exemplary embodiments of the application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the application.
