Description

Technical Field

[0001] This invention relates to the field of switching valve technology, and in particular to a switching valve with magnetic attraction. Background Technology

[0002] Switching valves are widely used in water effluent products, serving to switch the water outlet channel. Currently, most switching valves on the market only have a switching function, resulting in limited functionality. This is especially problematic when applied to multi-functional water effluent products, where each function occupies a separate installation area, leading to cluttered structures and limited design options. Therefore, this invention provides a composite switching valve that solves the problems of limited functionality and space requirements associated with existing switching valves. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this invention proposes a switching valve structure with a more optimized structure.

[0004] Firstly, a magnetic switching valve body mechanism is provided, including a water outlet seat, a switching valve body, and a magnetic component. Specifically,

[0005] The water outlet base is a water inlet component, including a water inlet channel, an installation cavity, and a water outlet channel connected in sequence. There are at least two water outlet channels, which are connected to the installation cavity through different connecting ports, so that different water outlets or different water dispensers can be achieved by switching the water path.

[0006] The switching valve body is installed inside the mounting cavity, and the operating part of the switching valve body is located outside the mounting cavity for the user to operate the water circuit switching. The switching valve body switches the connection between any water outlet channel and the water inlet channel through the operation of the operating part.

[0007] The magnetic suction assembly includes a first magnetic suction element and is located at the operating part of the switching valve body. That is, the magnetic suction assembly is installed on the switching valve body, so there is no need to reserve or design an additional position for the magnetic suction assembly on the water outlet seat.

[0008] The magnetic switching valve provided by this invention not only has a water outlet switching function, but also a water outlet suspension installation function. Furthermore, the corresponding magnetic component is configured on the operating part of the switching valve body, integrating the magnetic component and the switching valve body onto the same valve body. When using the switching valve provided by this invention, there is no need to reserve or design a position for the magnetic component on the water outlet product, freeing up space for other structural designs and avoiding the limitation of water outlet seat design. In addition, the water outlet seat, originally a complex and large-sized important component, has a simpler structure, which is conducive to improving the overall production efficiency of water-using products and reducing production costs. Moreover, by separating the magnetic component from the water outlet seat, it can be replaced separately if damaged during later use, resulting in low maintenance costs.

[0009] Preferably, the water outlet is connected to a water outlet channel of the water outlet seat via a flexible hose. A second magnetic element is provided around the periphery of the water outlet.

[0010] At least one of the second magnetic suction element and the first magnetic suction element includes a magnet, and the water dispenser is mounted on the water outlet base by the attraction force between the second magnetic suction element and the first magnetic suction element.

[0011] Preferably, the operating part is located on the front of the water outlet (facing the user), the magnetic suction component is located at the end of the operating part, and the second magnetic suction component is located on the back of the water outlet (facing away from the user), which facilitates the suspension of the water outlet and the operation of switching water flow.

[0012] Preferably, the magnetic attraction assembly further includes a mounting shell, one end of which is assembled together with the operating part of the switching valve body; alternatively, the mounting shell and the operating part are the same component. The other end of the mounting shell has a receiving cavity, and the first magnetic attraction element is disposed within the receiving cavity.

[0013] Preferably, the end of the mounting shell is spherical, the second magnetic suction component is provided with a bowl-shaped adsorption groove, and the water outlet and the water outlet seat swing and connect, thereby improving the flexibility of the water outlet direction.

[0014] Preferably, to reduce the molding difficulty caused by the integral molding of the magnetic suction component, the mounting shell includes a shell and a cover. One end of the shell is assembled with the operating part of the switching valve body through a threaded, screwed, snap-fit, interference fit, adhesive, or pin structure, and is coaxial with the operating part. The other end is assembled with the cover to form the spherical end. In addition, the cover as a whole or at its end is made of non-slip plastic material to increase resistance and facilitate the orientation of the water outlet.

[0015] Preferably, the operating part of the switching valve body switches the water path by rotating, pressing or sliding, or the water outlet drives the operating part and drives the switching valve body to switch the water path.

[0016] Preferably, the switching valve body is a rotary switching valve body, the operating part is a knob, and a rotating handle is provided around its periphery. The water outlet is magnetically attached to the water outlet seat. A concave-convex limiting structure is provided between the back of the water outlet and the operating part. The limiting structure forms a limited state and a free state by the swing of the water outlet. In the limited state, rotating or operating the water outlet will drive the knob to rotate through the limiting structure, so that the user does not need to remove the water outlet when water circuit switching is required, thus improving the convenience of use.

[0017] Preferably, the limiting structure includes a docking groove and a docking protrusion. A boss is provided on the back of the water outlet, and a mounting groove is provided in the middle of the boss. The second magnetic suction member is installed in the mounting groove, and multiple docking grooves surround the periphery of the mounting groove. Multiple docking protrusions are provided on the end face of the operating part and surround the magnetic suction assembly. The docking grooves and docking protrusions dock or separate through the swinging motion of the water outlet, forming the limited state and the free state. The structure is simple and highly convenient to use.

[0018] Preferably, the mating groove is located at the edge of the end face of the boss, and the bottom surface of the mating groove forms an inclined surface that extends to the end face and circumferential surface of the boss, forming a groove with open ends, which can prevent dirt and grime from accumulating in the mating groove.

[0019] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0020] The magnetic switching valve body mechanism provided by this invention not only has the function of switching water outlets, but also the function of suspending and installing the water outlet. At the same time, the corresponding magnetic components are configured on the operating part of the switching valve body, integrating the magnetic components and the switching valve body into the same valve body. On the one hand, the water outlet seat does not need to reserve or design a position for the magnetic components, freeing up space for other structural designs and avoiding the problem of limited design of the water outlet seat. On the other hand, the water outlet seat, as an important component that was originally complex and large in size, has a simpler structure, which is conducive to improving the overall production efficiency of water-using products and reducing production costs.

[0021] This invention separates the magnetic suction component from the water outlet base, allowing for individual replacement if damaged during later use, resulting in low maintenance costs.

[0022] The water outlet and the water outlet base are oscillating and connected, thereby improving the flexibility of the water outlet direction;

[0023] The water outlet can be linked to the operating unit and drive the switching valve body to switch the water path. When the water path needs to be switched, the user does not need to remove the water outlet, which improves the convenience of use. Attached Figure Description

Detailed Implementation

[0039] To make the technical problems, technical solutions, and beneficial effects of this invention clearer and more understandable, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] Please see Figures 1 to 12 A magnetically attached switching valve includes a water outlet seat 1, a switching valve body 2, and a magnetic attachment assembly 3. Specifically,

[0041] The water outlet base 1 is a water inlet component, comprising a water inlet channel 11, a mounting cavity 12, and a water outlet channel 13 connected in sequence. There are at least two water outlet channels 13, each connected to the mounting cavity 12 via different connecting ports, allowing for the switching of water paths to achieve water output from different nozzles or different water outlets. It should be noted that the water inlet channel 11 and the water outlet channel 13 extend to form connecting interfaces, which is existing technology and will not be described further here.

[0042] The switching valve body 2 is installed inside the mounting cavity 12, and the operating part 21 of the switching valve body 2 is located outside the mounting cavity 12 for the user to operate the water circuit switching. The switching valve body 2 switches the connection between any water outlet channel 13 and the water inlet channel 11 through the operation part 21. It should be noted that the specific structure of the valve core part of the switching valve body 2 is not limited here.

[0043] The magnetic suction assembly 3 includes a first magnetic suction element 31 and is disposed at the operation part 21 of the switching valve body 2. That is, the magnetic suction assembly 3 is installed on the switching valve body 2, so there is no need to reserve or design an additional position for the magnetic suction assembly 3 on the water outlet seat 1.

[0044] The water outlet 4 is connected to a water outlet channel 13 of the water outlet base 1 via a flexible hose. A second magnetic suction member 41 is provided around the periphery of the water outlet 4. At least one of the second magnetic suction member 41 and the first magnetic suction member 31 includes a magnet, and the water outlet 4 is mounted on the water outlet base 1 by the attraction force between the second magnetic suction member 41 and the first magnetic suction member 31. In this embodiment, the operating part 21 is located on the front of the water outlet base 1, the magnetic suction assembly 3 is located at the end of the operating part 21, and the second magnetic suction member 41 is located on the back of the water outlet 4, facilitating the suspension of the water outlet 4 and the switching of water flow.

[0045] In one embodiment, the magnetic suction assembly 3 further includes a mounting shell 32. One end of the mounting shell 32 is assembled together with the operating part 21 of the switching valve body 2, or the mounting shell 32 and the operating part 21 are the same component. The other end of the mounting shell 32 is provided with a receiving cavity, and the first magnetic suction member 31 is disposed in the receiving cavity. Preferably, the end of the mounting shell 32 is spherical, and the second magnetic suction member 41 is provided with a bowl-shaped adsorption groove 411 and is fixed to the back of the water outlet 4 by screws. The water outlet 4 swings and connects with the water outlet seat 1, thereby improving the flexibility of the water outlet direction of the water outlet 4.

[0046] Based on the above embodiments, in order to reduce the molding difficulty caused by the one-piece molding of the magnetic suction component 3, the mounting shell 32 includes a shell and a shell cover. One end of the shell is assembled with the operating part 21 of the switching valve body 2 by means of threads, screws, buckles, interference fits, adhesives or pins, and is coaxial with the operating part 21. The other end is assembled with the shell cover and forms the spherical end 321. In addition, the shell cover as a whole or at its end is made of non-slip plastic material to increase resistance and facilitate the orientation of the water outlet 4.

[0047] Preferably, the operating part 21 of the switching valve body 2 switches the water path by rotating, pressing or sliding, or the water outlet 4 is linked to the operating part 21 and drives the switching valve body 2 to switch the water path.

[0048] For example, in one embodiment, the switching valve body 2 rotates, and the operating part 21 is a knob with a rotating handle on its periphery. The water outlet 4 is attached to the water outlet seat 1 by a magnetic suction assembly 3. A concave-convex limiting structure is provided between the back of the water outlet 4 and the operating part 21. The limiting structure forms a limited state and a free state by the swing of the water outlet 4. In the limited state, rotating or operating the water outlet 4 will drive the knob to rotate through the limiting structure, so that when water circuit switching is required, the user does not need to remove the water outlet 4, improving the convenience of use.

[0049] Preferably, the limiting structure includes a docking groove 421 and a docking protrusion 211. A protrusion 42 is provided on the back of the water outlet 4, and a mounting groove is provided in the middle of the protrusion 42. The second magnetic suction member 41 is installed in the mounting groove, and multiple docking grooves 421 surround the periphery of the mounting groove. Multiple docking protrusions 211 are provided on the end face of the operating part 21 and surround the magnetic suction assembly 3. The docking grooves 421 and docking protrusions 211 dock or separate by the swinging motion of the water outlet 4, forming the limited state and the free state. The structure is simple and highly convenient to use.

[0050] In practical use, the user attaches the water dispenser 4 to the water outlet base 1 via the magnetic suction component 3. At this time, the centers of the docking groove 421 and the docking protrusion 211 are automatically positioned by the suction action of the water dispenser 4. The user only needs to slightly rotate the water dispenser 4 to quickly achieve engagement between the docking groove 421 and the docking protrusion 211. When switching the water dispensing state, the user can directly rotate the water dispenser 4, causing it to rotate around the magnetic suction component 3, and simultaneously rotate the knob. When the knob is rotated to the desired position, the user then swings the water dispenser 4 to separate the docking groove 421 from the docking protrusion 211. Afterward, the water dispenser is rotated back to the normal angle. Clearly, the magnetic suction component 3 provided by this invention also has the function of automatically aligning the limiting structure, improving the convenience, efficiency, and accuracy of the switching operation.

[0051] Based on the above embodiments, the mating groove 421 is provided on the edge of the end face of the boss 42, and the bottom surface of the mating groove 421 forms an inclined surface that extends to the end face and peripheral surface of the boss 42, forming a groove with open ends, which can prevent dirt and grime from accumulating inside the mating groove 421.

[0052] It should be noted that the magnetic switching valve provided by the present invention can be used in various water outlet products, including but not limited to showers. Meanwhile, the water outlet 4 includes but is not limited to shower heads.

[0053] The magnetic switching valve provided by this invention not only has the function of suspending and installing the water outlet 4, but also arranges the corresponding magnetic component 3 on the operating part 21 of the switching valve body 2, integrating the magnetic component 3 with the switching valve body 2. On the one hand, the water outlet seat 1 does not need to reserve or design a position for the magnetic component 3, freeing up space for other structural designs and avoiding the problem of limited design of the water outlet seat 1. On the other hand, the water outlet seat 1, as an important component that was originally complex and large in size, has a simpler structure, which is conducive to improving the overall production efficiency of water-using products and reducing production costs. At the same time, by separating the magnetic component 3 from the water outlet seat 1, it can be replaced separately when damaged in later use, resulting in low maintenance costs.
