Technical Field

[0001] This application relates to the field of fluid transport technology, and in particular to a leak-proof structure and a fluid transport device. Background Technology

[0002] In fluid transfer devices, pipe interfaces are used to install water outlet components. Water needs high pressure to flow from the pipe interface to the water outlet components to enable them to work properly. However, high water pressure may cause the water outlet components to detach, resulting in water leakage in the fluid transfer device and thus wasting water resources. Utility Model Content

[0003] The main purpose of this application is to propose a leak-proof structure and fluid transmission device, which aims to solve the problem of water leakage in the fluid transmission device after the water outlet component falls off.

[0004] To achieve the above objectives, the water-proof structure proposed in this application includes a fixing part, a pressure-bearing part, and a sealing element. The pressure-bearing part and the sealing element are respectively disposed on both axial sides of the fixing part. The pressure-bearing part is movably connected to the fixing part and is kinetically connected to the sealing element.

[0005] In one embodiment, the pressure-receiving part and the fixing part are movably connected by an elastic member, one end of which is connected to the pressure-receiving part and the other end of which is connected to the fixing part.

[0006] In one embodiment, the pressure-receiving part and the sealing element are connected by a connecting rod. The connecting rod extends in a direction parallel to the axial direction of the fixing part and is movable relative to the fixing part. One end of the connecting rod is connected to the pressure-receiving part, and the other end is connected to the sealing element.

[0007] In one embodiment, the connecting rod passes through the fixing part.

[0008] In one embodiment, the elastic element is sleeved on the outer periphery of the connecting rod, with one end abutting against the pressure-receiving part and the other end abutting against the fixing part.

[0009] In one embodiment, a plurality of connecting rods are provided, and the plurality of connecting rods are spaced apart circumferentially along the fixing portion.

[0010] In one embodiment, the pressure-receiving part is arranged in a ring shape, and a plurality of the connecting rods are connected to one of the pressure-receiving parts.

[0011] In one embodiment, the fixing part is arranged in a ring shape.

[0012] In one embodiment, the seal is provided in the form of a sheet, and the diameter of the seal is greater than or equal to the inner diameter of the fixing part.

[0013] This application also proposes a fluid transfer device, including the aforementioned leak-proof structure.

[0014] In one embodiment, the fluid transfer device has an inner cavity and an inlet, an outlet, and a pipe interface communicating with the inner cavity. The pipe interface includes a connected mounting section and a connecting section. The connecting section is disposed close to the inner cavity. The fixing part is installed on the connecting section. The mounting section is used to install the water outlet assembly. At least when the sealing element is located in the position of blocking the pipe interface, the pressure-bearing part extends into the mounting section.

[0015] In one embodiment, the inner wall of the inner cavity is recessed into a first receiving groove on the opposite side of the pipe interface, and when the seal is in the position where the pipe interface is open, the seal is received in the first receiving groove.

[0016] In one embodiment, the thickness of the fixing part is less than the length of the connecting segment in its axial direction, such that the fixing part and the inner peripheral wall of the connecting segment form a second receiving groove, and when the sealing member is located at the position of sealing the pipe interface, the sealing member is received in the second receiving groove.

[0017] In one embodiment, the inner peripheral wall of the mounting section is provided with threads.

[0018] In one embodiment, the fluid transfer device is configured as a pipe connector.

[0019] The technical solution of this application allows the pressure-bearing part to be movably connected to the fixing part and to the sealing part through a transmission connection. This allows the pressure-bearing part to move the sealing part to the position of opening the pipe interface under the pressure of the water outlet component, so that water can flow from the pipe interface to the water outlet component. Furthermore, when the water outlet component falls off, the sealing part can be moved to the position of sealing the pipe interface, so as to seal the pipe interface in time and prevent water waste, thereby solving the problem of water leakage in the fluid transmission device after the water outlet component falls off.

[0035] This application proposes a water-proof structure 100.

[0036] Please see Figures 1 to 7 In one embodiment of this application, the leak-proof structure 100 includes a fixing part 110, a pressure-bearing part 120 and a sealing member 130; the pressure-bearing part 120 and the sealing member 130 are respectively disposed on both axial sides of the fixing part 110, the pressure-bearing part 120 is movably connected to the fixing part 110 and is drively connected to the sealing member 130.

[0037] Specifically, the fixing part 110 is used to fix it to the inner wall of the pipe interface 200. The fixing part 110 can be integrally formed with the inner wall of the pipe interface 200 to achieve a fixed connection, or it can be fixed to the inner wall of the pipe interface 200 by welding or other methods. The fixing part 110 protrudes relative to the inner wall of the pipe interface 200 to support the entire leak-proof structure 100 and ensure that other components can be correctly installed and function properly; at the same time, it also serves to abut against the sealing element 130 to seal the pipe interface 200.

[0038] The pressure-bearing part 120 is located on one side of the fixing part 110 and is movably connected to the fixing part 110. The main function of the pressure-bearing part 120 is to generate displacement under the action of external force, and then realize the change of position of the sealing element 130 through the transmission connection with the sealing element 130. The pressure-bearing part 120 can move relative to the fixing part 110. When the pressure-receiving part 120 is subjected to pressure, it moves toward the fixing part 110, while the sealing element 130 moves away from the fixing part 110. As a result, the pressure-receiving part 120 drives the sealing element 130 to the position of opening the pipe interface 200, thereby opening the pipe interface 200 and allowing water to flow through. Conversely, when there is no external pressure, the pressure-receiving part 120 moves away from the fixing part 110, while the sealing element 130 moves toward the fixing part 110. As a result, the pressure-receiving part 120 drives the sealing element 130 to the position of sealing the pipe interface 200, thereby sealing the pipe interface 200 and closing the pipe interface 200 to prevent water from flowing away from the pipe interface 200.

[0039] The sealing element 130 can switch between the open and closed positions of the pipe interface 200. Even if the water outlet component 600 at the pipe interface 200 falls off, the sealing element 130 can promptly seal the pipe interface 200, preventing leakage and water waste, and ensuring that other water outlet components 600 still have sufficient water pressure to continue operating. Furthermore, when the water outlet component 600 is reinstalled at the pipe interface 200, the pressure-bearing part 120, under external force, moves the sealing element 130 to the open position of the pipe interface 200, allowing the water outlet component 600 to be used again. The position of the sealing element 130 is switched according to the force state of the pressure-bearing part 120, making the operation simple and quick, convenient for users and maintenance.

[0040] The technical solution of this application is that the pressure-bearing part 120 is movably connected to the fixing part 110 and is driven to the sealing member 130, so that the pressure-bearing part 120 can drive the sealing member 130 to the position of opening the pipe interface 200 under the pressure of the water outlet assembly 600, so that water flows from the pipe interface 200 to the water outlet assembly 600; and when the water outlet assembly 600 falls off, it can drive the sealing member 130 to the position of sealing the pipe interface 200, so as to seal the pipe interface 200 in time and prevent water waste, thereby solving the problem of water leakage in the fluid transmission device 10 after the water outlet assembly 600 falls off.

[0041] In one implementation, please refer to Figure 1 and Figure 2 The pressure-receiving part 120 and the fixing part 110 are movably connected by an elastic member 140, one end of which is connected to the pressure-receiving part 120 and the other end is connected to the fixing part 110.

[0042] The elastic element 140 is located between the pressure-bearing part 120 and the fixing part 110. When the sealing element 130 is in the position of blocking the pipe interface 200, the elastic element 140 provides a restoring force to the pressure-bearing part 120, so that when the external pressure is removed, the pressure-bearing part 120 can automatically reset under the action of the elastic element 140, thereby driving the sealing element 130 from the blocked position to the open position. The elastic element 140 enables the leak-proof structure 100 to have the ability to automatically reset. When the water outlet component 600 falls off, the sealing element 130 can automatically switch from the open position to the blocked position without human intervention. The leak-proof structure 100 can respond quickly and seal in time to prevent water leakage, improving the convenience of using the leak-proof structure 100. The elastic element 140 can be configured as a spring, bellows, rubber gasket, etc.

[0043] For other implementations, please refer to Figure 3 The pressure-bearing part 120 and the fixing part 110 can also be connected by a magnetic system. The pressure-bearing part 120 and the fixing part 110 are respectively equipped with mutually repulsive magnetic elements 160. When the external pressure disappears, the mutual repulsion between the pressure-bearing part 120 and the fixing part 110 enables the pressure-bearing part 120 to reset.

[0044] In one implementation, please refer to Figure 1 and Figure 2 The pressure-bearing part 120 and the sealing element 130 are connected by a connecting rod 150. The extension direction of the connecting rod 150 is parallel to the axial direction of the fixing part 110 and it can move relative to the fixing part 110. One end of the connecting rod 150 is connected to the pressure-bearing part 120 and the other end is connected to the sealing element 130.

[0045] The position of the seal 130 can be precisely controlled by the linear movement of the connecting rod 150 along the axial direction of the fixed part 110. When the pressure-bearing part 120 is subjected to external pressure, the pressure-bearing part 120 pushes the seal 130 to the open position via the connecting rod 150; when the external pressure disappears, the elastic element 140 causes the connecting rod 150 to drive the seal 130 back to the sealing position. As a transmission component between the pressure-bearing part 120 and the seal 130, the connecting rod 150 can stably transmit the force from the pressure-bearing part 120 to the seal 130, realizing the transmission connection between the pressure-bearing part 120 and the seal 130. The connecting rod 150 is not only simple in structure and easy to manufacture, but also reduces the impact on water flow. The connecting rod 150 can be a solid rod or a hollow tube.

[0046] In one implementation, please refer to Figure 1 and Figure 2 The connecting rod 150 passes through the fixing part 110.

[0047] The connecting rod 150 extends along the axial direction of the fixing part 110 and passes through the fixing part 110. That is, the fixing part 110 has a through hole for the connecting rod 150 to pass through. The connecting rod 150 can slide freely inside the fixing part 110 without disengaging from it, ensuring that the connecting rod 150 can only move linearly along the axial direction, avoiding lateral offset or tilting, thereby ensuring precise control of the position of the sealing element 130 and improving the sealing performance of the sealing element 130 when it is in the sealing position. At the same time, the fixing part 110 provides stable support for the movement of the connecting rod 150, ensuring that the connecting rod 150 will not shake or jam during movement, improving the operational stability of the entire leak-proof structure 100. In addition, the connecting rod 150 passing through the fixing part 110 makes the entire leak-proof structure 100 more compact and the connection more reliable.

[0048] In other embodiments, the connecting rod 150 may not pass through the fixing part 110. That is, the fixing part 110 does not need to have a through hole through which the connecting rod 150 passes. Please refer to Figure 4 For example, the fixing part 110 and the pressure-bearing part 120 are both annular, and the connecting rod 150 passes through the inner annular area of ​​the fixing part 110. One end of the connecting rod 150 is provided with a connecting protrusion, which connects to the pressure-bearing part 120.

[0049] In one implementation, please refer to Figure 1 and Figure 2 The elastic element 140 is sleeved on the outer periphery of the connecting rod 150, with one end abutting against the pressure receiving part 120 and the other end abutting against the fixing part 110.

[0050] The connecting rod 150 passes through the fixing part 110, and the elastic element 140 is sleeved on the outer periphery of the connecting rod 150, making the entire leak-proof structure 100 more compact. At the same time, the installation and replacement of the elastic element 140 are more convenient, reducing maintenance time and costs. It can reduce failures caused by loosening or falling off of the elastic element 140, improving the reliability of the leak-proof structure 100. It can ensure that the installation position and working state of all elastic elements 140 are consistent, reducing performance differences caused by installation errors and improving the overall consistency of the leak-proof structure 100.

[0051] In other embodiments, the elastic element 140 is not sleeved on the outer periphery of the connecting rod 150, and can be directly connected to the pressure-bearing part 120 and the seal 130; alternatively, a guide shaft can be provided, which passes through the fixing part 110, and the elastic element 140 is sleeved on the guide shaft.

[0052] In one implementation, please refer to Figure 1 and Figure 2 Multiple connecting rods 150 are provided, and the multiple connecting rods 150 are spaced apart along the circumference of the fixing part 110.

[0053] Multiple connecting rods 150 are spaced circumferentially along the fixed part 110, forming a multi-point linkage mechanism. This makes the force transmission between the pressure-bearing part 120 and the sealing element 130 more uniform and stable, avoiding the skew or uneven force problems that may be caused by a single connecting rod 150. It ensures smoother and more precise switching of the sealing element 130 between the sealing and opening positions, reduces shaking and jamming during movement, and improves the operational stability of the leak-proof structure 100. Multiple connecting rods 150 share the external pressure, distributing the stress points and reducing the load on each connecting rod 150, thus enhancing the overall load-bearing capacity of the leak-proof structure 100, making it suitable for environments with high water pressure. Even if a single connecting rod 150 is damaged, it does not affect the transmission function of the other connecting rods 150, and the leak-proof structure 100 can still function normally.

[0054] In other embodiments, a single connecting rod 150 may be provided, with the connecting rod 150 located on the axis of the fixing part 110.

[0055] In one implementation, please refer to Figure 1 and Figure 2 The pressure-bearing part 120 is arranged in a ring shape, and multiple connecting rods 150 are connected to one pressure-bearing part 120.

[0056] The annular pressure-bearing portion 120 is evenly distributed around the outer periphery of the fixed portion 110, ensuring uniform force distribution. When external pressure is applied to the pressure-bearing portion 120, the entire annular pressure-bearing portion 120 moves axially, causing the connecting rod 150 and the sealing element 130 to move synchronously. Multiple connecting rods 150 are connected to the annular pressure-bearing portion 120, making the force transmission between the pressure-bearing portion 120 and the sealing element 130 more uniform and stable. This results in a smoother movement of the leak-proof structure 100, reducing shaking and jamming, and improving the overall stability of the leak-proof structure 100.

[0057] In other embodiments, the pressure-bearing portion 120 may also be a protrusion formed at the end of the connecting rod 150. Each end of the connecting rod 150 has a pressure-bearing portion 120 with a certain area for the elastic member 140 to abut against and for the water supply assembly 600 to abut against. The pressure-bearing portion 120 may be a pin, abutment plate, etc.

[0058] In one implementation, please refer to Figure 1 and Figure 2 The fixing part 110 is arranged in a ring shape.

[0059] The annular fixing parts 110 are evenly distributed on the inner wall of the pipe interface 200, making the connection between the fixing parts 110 and the pipe interface 200 more secure and reliable. Simultaneously, the annular fixing parts 110 have better structural strength, allowing them to provide stable support points. The annular fixing parts 110 increase the contact area between the fixing parts 110 and the sealing element 130 at the sealing position, enabling the sealing element 130 to better seal the pipe interface 200, improving the sealing effect and reducing the possibility of leakage.

[0060] In other embodiments, a plurality of fixing parts 110 are spaced apart along the inner peripheral wall of the pipe interface 200.

[0061] In one embodiment, the seal 130 is provided in the form of a sheet, and the diameter of the seal 130 is greater than or equal to the inner diameter of the fixing part 110.

[0062] The sheet-like seal 130 can cover the inner ring area of ​​the fixing part 110. When the seal 130 is in the blocking position, the seal 130 blocks the inner ring area of ​​the fixing part 110, forming a tight sealing interface, ensuring that water cannot flow out from the inner ring area of ​​the fixing part 110, thereby achieving a good blocking effect and effectively preventing water leakage.

[0063] In one embodiment, the diameter of the sealing member 130 is equal to the inner diameter of the fixing part 110. When the sealing member 130 is in the blocking position, the outer peripheral wall of the sealing member 130 abuts against the inner ring wall of the fixing part 110, which can completely cover the inner ring area of ​​the fixing part 110 and realize the blocking of the pipe interface 200.

[0064] In another implementation, please refer to Figure 2 The diameter of the sealing element 130 is larger than the inner diameter of the fixing part 110. When the sealing element 130 is in the blocking position, the side of the sealing element 130 facing the pressure part 120 abuts against the side of the fixing part 110 away from the pressure part 120, which can completely cover the inner ring area of ​​the fixing part 110 and realize the blocking of the pipe interface 200.

[0065] In other embodiments, the seal 130 is provided in a block shape. Alternatively, the seal 130 includes a first sealing portion and a second sealing portion, the first sealing portion being located on the side of the second sealing portion facing the pressure-bearing portion 120, the diameter of the first sealing portion being equal to the inner diameter of the fixing portion 110, and the diameter of the second sealing portion being larger than the inner diameter of the fixing portion 110; when the seal 130 is in the blocking position, the outer peripheral wall of the first sealing portion abuts against the inner ring wall of the fixing portion 110, and the portion of the second sealing portion protruding from the first sealing portion abuts against the side of the fixing portion 110 away from the pressure-bearing portion 120, so as to cover the inner ring area of ​​the fixing portion 110, thereby achieving the blocking of the pipe interface 200.

[0066] This application also proposes a fluid transmission device 10, which includes a leak-proof structure 100. The specific structure of the leak-proof structure 100 is as described in the above embodiments. Since this fluid transmission device 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0067] In one implementation, please refer to Figure 5 The fluid transmission device 10 has an inner cavity 300 and an inlet 400, an outlet 500 and a pipe interface 200 communicating with the inner cavity 300. The pipe interface 200 includes a connected installation section 210 and a connecting section 220. The connecting section 220 is located close to the inner cavity 300. A fixing part 110 is installed on the connecting section 220. The installation section 210 is used to install the water outlet assembly 600. At least when the sealing member 130 is located in the position of blocking the pipe interface 200, the pressure-bearing part 120 extends into the installation section 210.

[0068] The inner cavity 300 is used for water flow. The inlet 400, outlet 500, and pipe interface 200 are all connected to the inner cavity 300. During the process of water flowing from the inlet 400 to the outlet 500, some water can flow out from the water outlet assembly 600 through the pipe interface 200 for use. The pipe interface 200 includes a connected installation section 210 and a connecting section 220. The connecting section 220 is located close to the inner cavity 300 and is used to install the fixing part 110 of the leak-proof structure 100, ensuring that the leak-proof structure 100 can be firmly installed on the pipe interface 200. The installation section 210 is located away from the inner cavity 300 and is used to install the water outlet assembly 600, such as valves, nozzles, etc. Different water outlet assemblies 600 can be selected according to actual needs. When the seal 130 is in the sealed position, the pressure portion 120 extends into the installation section 210, ensuring that the water outlet assembly 600 can squeeze the pressure portion 120 after the water outlet assembly 600 is installed, so that the pressure portion 120 drives the seal 130 to move to the open position.

[0069] Understandably, please refer to Figure 7 When the water outlet component 600 extends into the installation section 210, the water outlet component 600 contacts the pressure receiving part 120. During the installation process, the water outlet component 600 drives the pressure receiving part 120 to move towards the inner cavity 300, and then drives the sealing element 130 to move away from the fixing part 110 through the connecting rod 150. At the same time, the elastic element 140 is compressed. When the sealing element 130 moves to the position of opening the pipe interface 200, the water can flow normally. That is, the water flows in from the inlet 400, part of it flows through the pipe interface 200 and flows out from the water outlet component 600 to enable the water outlet component 600 to work normally, and the other part of the water flows from the outlet 500 to the subsequent pipe.

[0070] Please see Figure 6 When the water outlet assembly 600 detaches, the compressed elastic element 140 immediately resets, and its elasticity causes the pressure-bearing part 120 to move away from the fixed part 110. This, through the connecting rod 150, moves the sealing element 130 toward the fixed part 110 to the position of sealing the pipe interface 200. At this time, the sealing element 130 seals the pipe interface 200 and maintains this state under the action of the elasticity of the elastic element 140 and water pressure, restricting the flow of water from the pipe interface 200. The water can only flow from the inlet 400 to the outlet 500. This ensures that the fluid transmission device 10 can prevent leakage and stop damage in time when the water outlet assembly 600 detaches, preventing further waste of water resources, and ensuring that the water outlet assemblies 600 in other positions still have sufficient water pressure to continue operating. When the water outlet assembly 600 is reinstalled, the sealing element 130 will move to the position of opening the pipe interface 200, allowing it to be put into use again.

[0071] The fluid transfer device 10 can transfer water or other fluid media that need to be transferred.

[0072] In one implementation, please refer to Figure 6 and Figure 7 The inner wall of the inner cavity 300 is recessed on the opposite side of the pipe interface 200, and when the sealing member 130 is in the position of opening the pipe interface 200, the sealing member 130 is accommodated in the first receiving groove 310.

[0073] The first receiving groove 310 is formed on the inner wall of the inner cavity 300 and is located on the opposite side of the pipe interface 200. The diameter of the first receiving groove 310 is approximately the same as the diameter of the seal 130, and the first receiving groove 310 can accommodate the seal 130. When the seal 130 is in the position where the pipe interface 200 is open, the seal 130 is pushed into the first receiving groove 310, which does not obstruct the flow of water and ensures the smooth passage of water. The first receiving groove 310 can protect the seal 130 and prevent it from being worn or damaged during the flow of water. The positioning of the seal 130 in the first receiving groove 310 is more stable, avoiding shaking or displacement caused by water flow impact.

[0074] In one implementation, please refer to Figure 8 The thickness of the fixing part 110 is less than the length of the connecting section 220 in its axial direction, so that the fixing part 110 and the inner peripheral wall of the connecting section 220 form a second receiving groove 320. When the sealing member 130 is located at the position of the sealing pipe interface 200, the sealing member 130 is received in the second receiving groove 320.

[0075] The fixing part 110 forms the bottom wall of the second receiving groove 320, and the inner peripheral wall of the connecting section 220 forms the side wall of the second receiving groove 320. The diameter of the second receiving groove 320 is approximately the same as the diameter of the sealing member 130, and the second receiving groove 320 can accommodate the sealing member 130. When the sealing member 130 is in the blocking position, the sealing member 130 is pushed into the second receiving groove 320, which can fit more tightly into the inner ring area of ​​the fixing part 110, forming a more effective sealing interface to prevent water leakage; it will not obstruct the flow of water in the direction of the outlet 500, ensuring the smooth passage of water; the second receiving groove 320 can protect the sealing member 130, preventing it from being worn or damaged during the flow of water to the outlet 500; the positioning of the sealing member 130 in the second receiving groove 320 is more stable, avoiding shaking or displacement caused by water flow impact.

[0076] In one implementation, please refer to Figure 6 and Figure 7 The inner circumferential wall of the installation section 210 is threaded.

[0077] The inner circumferential wall of the mounting section 210 is threaded, allowing for easy connection to various threaded water outlet components 600 (such as valves, nozzles, etc.). The threaded connection provides high connection strength and sealing performance, ensuring a tight connection between the water outlet component 600 and the mounting section 210, preventing leakage due to loose connections. The threaded design simplifies and speeds up installation, reducing installation time and improving efficiency; furthermore, the water outlet component 600 can be easily disassembled and replaced, facilitating routine maintenance and repairs.

[0078] In other embodiments, the water outlet component 600 is engaged with the inner peripheral wall of the mounting section 210. One of the outer peripheral wall of the water outlet component 600 and the inner peripheral wall of the mounting section 210 is provided with a groove, and the other is provided with a protrusion. The protrusion is engaged in the groove to realize the connection between the water outlet component 600 and the mounting section 210.

[0079] In one implementation, please refer to Figure 5 The fluid transfer device 10 is configured as a pipe connector.

[0080] The pipe connector is used to connect the inlet pipe, the outlet pipe, and the outlet assembly 600. At least one interface of the pipe connector is a pipe interface 200 for mounting the outlet assembly 600. A leak-proof structure 100 is installed at the pipe interface 200 corresponding to the pipe connector. If the outlet assembly 600 detaches, the seal 130 can promptly seal the pipe interface 200 to prevent leakage. The leak-proof structure 100 and the pipe connector are not only simple and reliable in structure, suitable for various scenarios, and reusable, but also have a minimalist design and are easy to manufacture.

[0081] In other embodiments, the fluid transfer device 10 may be configured as a fluid conduit, such as a water pipe.
