Description

Technical Field

[0001] This utility model relates to bathroom product accessories, specifically to shower faucet curved feet accessories in bathroom products. Background Technology

[0002] Curved feet for shower faucets are primarily used to connect the hot and cold water inlets of the shower faucet body (or other water outlet valves with similar shower faucet body structures) to the wall-mounted hot and cold water pipe connections with adjustable spacing. The curved feet reduce the accuracy requirements for the spacing of the hot and cold water pipe connections on the wall, making it easier to install and use the shower faucet. Of course, curved feet can also be used for the installation of other similar shower faucets.

[0003] The installation of shower faucet feet, like other faucets and angle valves in the kitchen and bathroom industry, presents the same problems as water pipe connections during installation, specifically: 1. Before installing faucets, angle valves, or shower faucet feet, a plug wrapped with Teflon tape is needed to seal the water pipe connection to prevent water leakage and protect the interface. This is cumbersome, and plugs and Teflon tape are not readily available, adding to the difficulty of disassembly and assembly; 2. The aforementioned problems, along with the installation of faucets, angle valves, and shower faucet feet, directly lead to the need for repeated switching of the main water valve for various disassembly, assembly, and leak testing operations, which is inconvenient; 3. Professional operation is usually required to prevent leaks, causing inconvenience in daily life; 4. In the event of bursting, broken, or leaking faucets, angle valves, or shower faucets, it is impossible to stop the water flow in time. These problems are further exacerbated by the installation of shower faucet feet, which are adapter components. Furthermore, the existing structure of faucet feet does not allow for the purchase of replacement parts that can solve these problems, thus requiring urgent improvement.

[0004] In view of this, the inventor of this case devoted time, energy and funds to improving the structure of the curved foot of the shower faucet and conducted trial production tests, which led to the creation of this case. Summary of the Invention

[0005] The purpose of this utility model is to provide a self-sealing, one-way water-stopping, explosion-proof shower faucet curved foot that, in addition to its adapter function, can also achieve self-sealing water-stopping, switching, explosion-proof and / or backflow prevention functions without the need for Teflon tape, making it easy to install and use.

[0006] To achieve the above objectives, the technical solution of this utility model is: a self-sealing one-way water-stopping and explosion-proof shower faucet curved leg, comprising a curved leg body having a connected inlet end and an outlet end, wherein a self-sealing one-way water-stopping component, an explosion-proof water-stopping component and / or an anti-backflow check component are provided on the curved leg body corresponding to the inlet end, or, a self-sealing one-way water-stopping component, an explosion-proof water-stopping component and / or an anti-backflow check component are provided on the curved leg body corresponding to the outlet end.

[0007] The self-sealing one-way water-stopping component includes a push-opening structure for pushing to open when the shower faucet is installed and connected, a self-resetting closing structure for closing when no shower faucet is installed and connected, a first component sealing structure for sealing between the shower faucet and the curved leg body, and a first component connecting structure for connecting with the curved leg body.

[0008] And / or, the explosion-proof water-stopping component includes an impact explosion-proof structure that can remain open when the water pressure is normal and change to a closed state when the water pressure changes abnormally, as well as a second component connection structure that realizes connection with the curved leg body or the self-sealing one-way water-stopping component and a second component sealing structure that realizes sealing between the curved leg body or the self-sealing one-way water-stopping component.

[0009] And / or, the anti-backflow check assembly includes an anti-backflow check structure that can be pushed into an open state when the water pressure and water flow direction are normal and can self-reset to a closed state, a third component connection structure that realizes connection with the curved foot body or the self-sealing one-way water stop assembly, and a third component sealing structure that realizes sealing between the curved foot body or the self-sealing one-way water stop assembly.

[0010] The self-sealing one-way water-stop component is provided corresponding to the outflow interface end, and the explosion-proof water-stop component and the anti-backflow check component are provided corresponding to the inflow interface end or the outflow interface end.

[0011] The self-resetting closing structure includes a one-way water-stop sleeve that is sealed and connected to the outlet interface and has two through ends, a central shaft that can be axially moved through the one-way water-stop sleeve and has water flow channels that can be connected to both ends of the one-way water-stop sleeve, and a sealing structure that is provided at the inner end of the central shaft and can seal and block the inner end of the one-way water-stop sleeve when the central shaft moves axially; the push opening structure is that the outer end of the central shaft has a push part that can be contacted and pushed when the shower faucet is installed and connected; the first component connection structure is that the one-way water-stop sleeve and the curved leg body are integrally sealed and connected or connected through a sealed assembly connection structure provided between the two.

[0012] And / or, the anti-backflow check structure includes a check sleeve that is sealed and connected to the inflow or outflow interface and has a through flow port and a check flow port at its two ends, respectively; a movable rod that passes through the check sleeve through an axial guide structure; a sealing component that is provided on the movable rod facing the check flow port and can seal and block the check flow port; and a check support elastic element that is sleeved on the movable rod, abuts against the sealing component, and can be pushed and compressed by normal water pressure.

[0013] And / or, the impact explosion-proof structure includes an explosion-proof sleeve with a normal flow port and an explosion-proof flow port at its two ends respectively, an explosion-proof movable block embedded in the explosion-proof sleeve and movably sealing and blocking the explosion-proof flow port, and an explosion-proof support elastic member that is pushed and compressed by abnormal water pressure between the explosion-proof movable block and the inner side of the explosion-proof flow port.

[0014] The explosion-proof water-stop component and the anti-backflow check component are respectively provided at the outflow interface end; the check sleeve and the explosion-proof sleeve are connected by an integral sealing connection to form the second component sealing structure and the third component sealing structure, or they are connected by an assembly connection structure between the two and the second component sealing structure and the third component sealing structure to be installed on the water flow channel of the one-way water-stop sleeve or the central shaft.

[0015] The explosion-proof water-stopping component and the anti-backflow check component are provided at the corresponding inflow interface ends; the third component connection structure is that the check sleeve and the curved foot body are integrally sealed and connected to form the third component sealing structure, or the check sleeve and the curved foot body are connected by a set assembly connection structure and the connection and sealing are achieved by the third component sealing structure.

[0016] The third component connection structure is that the explosion-proof sleeve is integrally and sealed with the curved leg body or the check sleeve, thus forming the third component sealing structure;

[0017] Alternatively, the explosion-proof sleeve and the curved leg body are connected by an assembly connection structure and the connection is sealed by a third component sealing structure.

[0018] Alternatively, the explosion-proof sleeve and the check sleeve are connected by an assembly connection structure. The third component sealing structure is that the port corresponding to the inflow interface end is fitted with an inflow end sealing ring on the check sleeve. The inflow end sealing ring can be used to seal the inflow interface end and the water pipe joint when the shower faucet is installed with a curved foot.

[0019] The pushing part is a pushing disc formed by the outer end of the central shaft extending vertically outward. The first component sealing structure is a sealing ring that can contact and seal with the shower faucet interface and the outlet interface on the outer edge of the pushing disc. The central shaft and the one-way water-stop sleeve are provided with an anti-rotation nesting structure, and a water-stop support elastic element that supports the pushing disc is sleeved on the central shaft.

[0020] The inlet end of the curved leg body is provided with a leak-proof structure for a leak-proof and sealed connection with a water pipe connector. The leak-proof structure is a sealing connector accessory provided at the inlet end of the curved leg body, or the leak-proof structure is a sealing ring mounting section integrally extended from the inlet end of the curved leg body, and a sealing ring is fitted on the sealing ring mounting section.

[0021] By adopting the above technical solution, the beneficial effects of this utility model are as follows: the curved foot of the shower faucet in the above structure is provided with a self-sealing one-way water-stop component, an explosion-proof water-stop component and / or an anti-backflow check component on the curved foot body at the corresponding inlet or outlet end. In addition to the basic conversion function, it can also achieve the multi-functional effects of self-sealing water-stop, switching, explosion-proof and / or anti-backflow without Teflon tape.

[0022] Specifically, the self-sealing one-way water-stop component allows the shower faucet to be installed without the need for Teflon tape, and the shower faucet can also be installed on the water pipe joint first. Furthermore, the main water valve does not need to be turned off during the installation, disassembly, and leakage testing of the shower faucet, avoiding repeated trips. The water flow can be turned on at the same time as the shower faucet is installed, thus realizing the functions of self-sealing water-stopping and switching without Teflon tape.

[0023] Furthermore, the explosion-proof water-stopping component uses its impact-proof structure to shut off water flow when there is abnormal water pressure. When a component such as a shower faucet bursts and water leaks out, there will be a sudden increase in pressure, i.e., an abnormal change in water pressure. The impact-proof structure immediately blocks the water flow channel. After the abnormal water pressure disappears and returns to normal, the impact-proof structure automatically releases the blockage, thus achieving the function of explosion-proof water-stopping.

[0024] In addition, the anti-backflow check component can prevent hot water from flowing back into the cold water pipe when the cold water pipe is shut off. This is especially suitable for the installation of shower faucets with multiple control valves and multiple water output settings that are common in the market today. This is because the main valve core of a shower faucet with multiple control valves and multiple water output settings is normally open when not in use. When the cold water pipe is shut off, hot water will flow into the cold water pipe, thus achieving the backflow prevention function.

[0025] In summary, this design makes the curved base of the shower faucet easier to install and use, achieving the aforementioned objectives of this invention. The further structural design enhances the compactness and stability of the product structure, making it more durable. Furthermore, the design is easy to implement, suitable for widespread application, and ready for mass production. Attached Figure Description

[0037] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0038] This embodiment discloses a self-sealing, one-way water-stopping, explosion-proof shower faucet curved foot, such as... Figures 1-4 As shown, the device includes a curved body 1 with a connected inlet end 11 and an outlet end 12. The inlet end 11 is for connecting to a water pipe connector on the wall, and the outlet end 12 is for connecting to the water inlet of the shower faucet. The inlet end 11 and the outlet end 12 are usually eccentric and have different axes, thus enabling the conversion of the hot and cold water interfaces of the shower faucet with adjustable spacing. Hence, it is called a curved body. Curved bodies are common in the market, and there are various shapes of existing curved body bodies, as shown in the attached figure of this embodiment. It should be noted that although the name of this utility model is defined as a shower faucet curved body, it mainly describes its use in the conversion of shower faucets, but is not limited to its use in the conversion of shower faucets. The difference between the curved foot of this utility model and existing products lies in that a self-sealing one-way water-stop component 2, an explosion-proof water-stop component 3, and / or an anti-backflow check component 4 are provided on the curved foot body 1 corresponding to the inlet end 11; or, a self-sealing one-way water-stop component 2, an explosion-proof water-stop component 3, and / or an anti-backflow check component 4 are provided on the curved foot body 1 corresponding to the outlet end 12. Figure 1 and Figure 2The diagram shows the configuration settings for all three publicly disclosed components. Figure 3 , Figure 4 These represent different structural configurations, and the specific structural configuration can be selected according to usage requirements. The following description, in conjunction with the accompanying drawings, details the specific structural configurations of the main body and its components, as well as their positional connections.

[0039] The self-sealing one-way water-stop component 2, such as Figure 2 As shown, the system includes a push-to-open structure, a self-resetting to close structure, a first component sealing structure, and a first component connecting structure. The push-to-open structure is configured to allow the self-sealing one-way water-stop component 2 to move into an open state when the shower faucet (not shown) is installed. The self-resetting to close structure is configured to allow the self-sealing one-way water-stop component 2 to reset to a closed state when the shower faucet is not installed. Thus, the push-to-open structure and the self-resetting to close structure constitute the function of the shower faucet's foot switch. The foundation for the self-sealing one-way water-stop component 2 to function as a switch primarily relies on the stability of the structural connection and the sealing of leak-proof areas during assembly. Therefore, the first component sealing structure provides a leak-proof seal between the self-sealing one-way water-stop component 2 and the shower faucet and foot switch body 1. The first component connecting structure ensures a stable connection with the foot switch body 1.

[0040] In this embodiment, since the push-to-open structure needs to be able to open immediately upon installation and connection of the shower faucet, preferably, the self-sealing one-way water-stop component is provided corresponding to the outflow interface end 12, such as... Figure 1 and Figure 2As shown, the self-resetting closing structure includes a one-way water-stop sleeve 21, a central shaft 22, and a sealing structure 23. The one-way water-stop sleeve 21 is sealed and connected to the outlet port 12 through the first component connection structure. The two ends of the one-way water-stop sleeve 21 are interconnected. Here, the first component connection structure can be an integral sealing connection between the one-way water-stop sleeve 21 and the curved leg body 1. It can be integrally formed during the production of the curved leg body 1. After forming, the outer wall of the one-way water-stop sleeve 21 and the inner wall of the curved leg body 1 are completely connected and sealed, and there is no possibility of leakage between them. In addition to integral connection, it can also be connected by threaded sealing or other sealing assembly structures as shown in the figure. Assembly connection is beneficial to the simple assembly and manufacturing of components. The specific product structure setting can be selected according to the product design. The central shaft 22 is axially movable and passes through the one-way water-stop sleeve 21. The central shaft 22 also has water flow channels 221 at both ends that correspond to the two ends of the one-way water-stop sleeve 21. In this embodiment, the structure shown in the figure is designed for easy assembly. A corresponding shape-matched anti-rotation nesting structure (e.g., the corresponding mating sections are square) is provided between the central shaft 22 and the one-way water-stop sleeve 21 to restrict rotation. Thus, the one-way water-stop sleeve 21 cannot rotate relative to the central shaft 21. During installation, simply rotating the central shaft 22 (the outer end of the central shaft 22 may have a structure for tool engagement, such as an internal hexagon) drives the one-way water-stop sleeve 21 to achieve the one-way water-stop effect. The sleeve 21 is locked onto the curved body 1. The water flow channel 221, as shown in the figure, has a hollow structure with a through-hole at the outer end and a through-hole on the inner side wall. Thus, the water flow channel 221 can pass through both ends of the one-way water-stop sleeve 21. The sealing structure 23 is set at the inner end of the central shaft 22 and can seal and block the inner end of the one-way water-stop sleeve 21 when the central shaft 22 moves axially. As shown in the figure, a sealing rubber ring is fitted on the central shaft 22. When the sealing rubber ring does not block the inner end of the one-way water-stop sleeve 21, there is a gap between it and the inner end of the one-way water-stop sleeve 21, allowing water to enter and flow into the water flow channel 221 through the through-hole on the inner side wall of the central shaft 22. The self-resetting closing structure achieves self-resetting by pushing the inner end face of the central shaft 22 with water pressure when there is no pushing force, or by installing a water-stopping support spring 24 on the central shaft to keep the central shaft elastically supported in a state where the inner end of the one-way water-stopping sleeve 21 is blocked, as shown in the figure. Based on the self-resetting closing structure disclosed above, the push opening structure is provided with a push part 25 on the outer end of the central shaft 22, which can be contacted and pushed when the shower faucet is installed and connected; as shown in the figure, the push part is a push plate formed by the vertical outward extension of the outer end of the central shaft 22 (the two ends of the water-stopping support spring 24 are respectively pressed against the inner side of the push plate and the inner wall of the one-way water-stopping sleeve 21, which is simple in structure, stable in reset support, and also facilitates the assembly structure setting.The self-sealing one-way water-stop component 2, as described above, achieves the structural function of one-way water-stopping. Furthermore, in this embodiment, the self-sealing one-way water-stop component 2 achieves the effect of eliminating the need for Teflon tape as follows: the first component's sealing structure consists of a sealing ring 26 fitted onto the outer edge of the push plate, which can contact and seal with the shower faucet interface and the outlet end 12. During installation of the shower faucet interface, pushing the push plate causes the inner side of the sealing ring 26 to adhere to the end face of the outlet end 12, while the outer side adheres to the shower faucet interface, thus achieving a complete internal seal. This ensures that the outer end of the water flow channel 221 is sealed and connected to the shower faucet interface, preventing leakage and eliminating the need for Teflon tape.

[0041] Through the above structure, the outflow interface 12 of the curved leg body 1 achieves the functions of sealing, switching, water stoppage, and Teflon tape-free operation. To facilitate the use and installation of the overall shower faucet curved leg, if its inflow interface 11 has other component structures, its docking sealing and Teflon tape-free operation functions can be achieved through the following structure: a leak-proof structure is provided at the inflow interface 11 for a leak-proof sealing connection with the water pipe joint. Specifically, the leak-proof structure can be a sealing joint accessory (available directly from the market) at the inflow interface 11 of the curved leg body 1, or... Figure 4 The leak-proof structure shown is that a sealing ring mounting section 13 is integrally extended from the inlet end 11 of the curved body 1. A sealing ring 14 is fitted onto the sealing ring mounting section 13, and a seal is achieved through the sealing ring 14 and the water pipe joint. The structure is simple. Alternatively, if other component structures are provided, the above structure is not required, and a seal can be achieved through structural settings on other components, as described below.

[0042] This embodiment is attached. Figure 1 and 2As described above, the explosion-proof water-stopping component 3 and the anti-backflow check component 4 are provided for the corresponding inlet end 11. The anti-backflow check component 4 includes an anti-backflow check structure that can be pushed into an open state when the water pressure and water flow direction are normal and can self-reset to a closed state, a third component connection structure that realizes the connection with the curved leg body 1 or the self-sealing one-way water-stopping component 2, and a third component sealing structure that realizes the sealing between the curved leg body 1 or the self-sealing one-way water-stopping component 2 (here, with the curved leg body 1). Specifically, in this embodiment, the anti-backflow check structure includes a check sleeve 41 sealed within the inflow port 11 or the outflow port 12 (here, the inflow port 11), with its two ends being a through-flow port 411 (the outflow end of normal water flow) and a check flow port 412 (the inflow end of normal water flow), a movable rod 42 passing through the check sleeve 41 via an axial guide structure, a sealing component 43 disposed on the movable rod 42 facing the check flow port 412 and capable of sealing and blocking the check flow port 412, and a sealing component 43 sleeved on the movable rod 42 and pressing against the sealing component. The third component connection structure consists of a plugging component 43 and a check valve support elastic element 44 that can be pushed and compressed by normal water pressure. The check valve sleeve 41 and the curved leg body 1 are connected by an assembly connection structure (threaded structure, etc.) and sealed by a third component sealing structure. As shown in the figure, the outer wall of the check valve sleeve 41 and the inner wall of the curved leg body 1 are sealed by a sealing ring. Alternatively, the third component connection structure consists of the check valve sleeve 41 and the curved leg body 1 integrally sealed and connected to form the third component sealing structure (an integrally implemented sealing structure). With the above structure, during the installation and use of the shower faucet, when the cold water pipe is supplying water normally, it will push the plugging component 43 to move towards the flow port 411, and the anti-backflow check structure can pass water normally. When the cold water pipe is shut off, the plugging component 43 loses its pushing force and is pushed to the check flow port 412 by the elastic support of the check valve support elastic element 44 to block it. Therefore, the hot water in the shower faucet cannot flow into the cold water pipe, thus achieving the check valve function.

[0043] This embodiment is attached. Figure 1 and 2As shown, the explosion-proof water-stopping component 3 and the anti-backflow check component 4 are provided at the corresponding inlet end 11. The explosion-proof water-stopping component 3 includes an impact-proof explosion-proof structure that can remain open when the water pressure is normal and change to a closed state when the water pressure changes abnormally, a second component connection structure that connects to the curved leg body 1 or the self-sealing one-way water-stopping component 2, and a second component sealing structure that seals the connection between the component and the curved leg body 1 or the self-sealing one-way water-stopping component 2. The specific structure disclosed in this embodiment is shown in the figure. The impact explosion-proof structure includes an explosion-proof sleeve 31 with a normal flow port 311 (water inlet port) and an explosion-proof flow port 312 (water outlet port) at its two ends, an explosion-proof movable block 32 embedded in the explosion-proof sleeve 31 and movably sealing and blocking the explosion-proof flow port 312, and an explosion-proof support elastic element 33 that is pushed between the explosion-proof movable block 32 and the inside of the explosion-proof flow port 312 and can be pushed and compressed by abnormal water pressure. The structure is simple as shown in the figure. The explosion-proof support elastic element 33 is a spring element. By selecting an appropriate spring elastic coefficient, for example, the normal water pressure in the domestic water pipes in a typical household does not exceed 0.5 MPa, the spring can be selected with an elastic coefficient that can be compressed by water pressure greater than 0.5 MPa. In the event of an explosion-proof structure such as a faucet or angle valve, the spring can be optimized for compressibility. When a hose or other object bursts, the water pressure exceeds 0.5 MPa. The water flow pushes the explosion-proof movable block 32 toward the explosion-proof flow port 312 and blocks it, thus achieving immediate water stoppage upon bursting. Furthermore, it maintains the blockage of the explosion-proof flow port 312 until the water pressure anomaly is addressed, achieving the aforementioned objective of this invention. After the water pressure anomaly is resolved, the pressure that compresses the explosion-proof support elastic element 33 disappears. Under the elastic tension of the explosion-proof support elastic element 33, the explosion-proof movable block 32 automatically resets, the explosion-proof flow port 312 is unblocked, and the explosion-proof water-stopping component 3 immediately resumes flow. The water pressure returns to normal, and the explosion-proof water-stopping component 3 is in a normal state. It should be noted that the explosion-proof movable block 32 should be constructed in a way that does not affect water flow under normal conditions. In this embodiment, the second component connection structure and the second component sealing structure can have multiple structural configurations. Firstly, the second component connection structure is an integral sealing connection between the explosion-proof sleeve 31 and the curved leg body 1 or the check sleeve 41, forming the second component sealing structure (an integrally connected sealing structure). Secondly, the explosion-proof sleeve 31 and the curved leg body 1 are connected by an assembly connection structure (threaded structure, etc.) and the connection is sealed by the second component sealing structure (such as a sealing ring). Thirdly, the explosion-proof sleeve 31 and the check sleeve 41 are connected by an assembly connection structure (threaded structure, etc.), and the second component sealing structure has an inflow end sealing ring 45 fitted on the explosion-proof sleeve 31 or the check sleeve 41 at the port corresponding to the inflow interface 11. The inflow end sealing ring 45 can be used to seal the inflow interface 11 and the water pipe connector when the shower faucet curved leg is installed.

[0044] In the structural design of this utility model, the explosion-proof water-stopping component 3 and the anti-backflow check component 4 can also be provided at the corresponding outflow interface end. They can be integrated with the self-sealing one-way water-stopping component. For example, the check sleeve 41 and the explosion-proof sleeve 31 are connected to the water flow channel 221 of the one-way water-stopping sleeve 21 or the central shaft 22 by forming the second component sealing structure and the third component sealing structure through an integral sealing connection. Alternatively, the check sleeve 41 and the explosion-proof sleeve 31 are connected to the water flow channel 221 of the one-way water-stopping sleeve 21 or the central shaft 22 by an assembly connection structure provided between them and the water flow channel 221 of the one-way water-stopping sleeve 21 or the central shaft 22, and are connected to the water flow channel 221 of the one-way water-stopping sleeve 21 or the central shaft 22 through the second component sealing structure and the third component sealing structure.

[0045] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
