Water diversion device and water diversion assembly

Abstract

The application discloses a water distribution device and a water distribution assembly, and relates to the field of waterway switching. The water distribution device comprises a main body, a valve body, a push rod, a button and an elastic piece. When the push rod is in a first position, water is discharged from a first water outlet. When it is needed to switch to other waterways, the push rod is pressed to switch the push rod from the first position to a second position. In the process of position switching of the push rod, air in an air cavity is discharged to the outside through an air passage, so that the influence of water pressure on pressing force is small, and pressing is smooth. When the push rod is in the second position, water is discharged from a second water outlet. When a user closes an inlet, the water pressure in the main body is reduced, and the elastic force of the elastic piece resets the push rod to the first position. In the process, air from the outside enters the air cavity through the air passage, so that the push rod can be moved smoothly and reset. Therefore, after the total switch is closed each time, the water distribution device can connect the default waterway, which is convenient for user memory and effectively reduces the probability of misoperation.

Description

Technical Field

[0001] This invention relates to the field of water circuit switching, and in particular to a water distribution device and water distribution component. Background Technology

[0002] A main switch is installed on the inlet pipe to control its on / off state, while a water distribution device allows the same inlet pipe to supply water to different water circuits, thereby improving pipeline efficiency and reducing costs and installation complexity. For example, a water distribution device can be used between a showerhead and a bathtub faucet, or between the main kitchen sink faucet and a pull-out faucet, directing water flow to different circuits for switching water output. In related technologies, water distribution devices often use rotary controls to switch between different water circuits and modes; however, users may easily forget the current mode, leading to incorrect switching and a poor user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a water distribution device in which, after the water is turned off, the push rod in the water distribution device can automatically reset, reconnecting the default water path.

[0004] The present invention also proposes a water distribution assembly having the above-mentioned water distribution device.

[0005] A water separation device according to a first aspect embodiment of the present invention includes:

[0006] The main body is provided with an installation cavity and a first water inlet, a first water outlet, and a second water outlet communicating with the installation cavity;

[0007] A valve body is disposed within the mounting cavity, and the valve body is provided with a second inlet, a first outlet, and a second outlet.

[0008] A push rod is slidably disposed within the valve body, the push rod defining a first water distribution groove and a second water distribution groove, and an air cavity is defined between the push rod and the valve body; the first water distribution groove and the second water distribution groove are spaced apart along the axial direction of the push rod, and an air passage is defined inside the push rod, the two ends of the air passage being connected to the air cavity and the external space of the push rod, respectively;

[0009] An elastic element is used to provide a force that causes the push rod to return to its original position along the axial direction;

[0010] The push rod has a first position and a second position. When water flows through the first inlet and the push rod is in the first position, the first inlet is connected to the first outlet through the second inlet, the first water distribution channel, and the first water outlet. When water flows through the first inlet and the push rod is switched to the second position, the first inlet is connected to the second outlet through the second inlet, the second water distribution channel, and the second water outlet. When water is turned off at the first inlet and the push rod is in the second position, the elastic element can reset the push rod to the first position.

[0011] The water separation device according to embodiments of the present invention has at least the following beneficial effects:

[0012] When water flows through the first inlet and the push rod is in the first position, water flows sequentially through the first inlet, the second inlet, the first water distribution channel, and the first overflow outlet, finally exiting from the first outlet. When switching to another water path, the push rod is pressed to overcome the elastic force of the spring element, causing it to switch from the first position to the second position. During this switching process, the air chamber is compressed by the push rod, reducing its volume, and the air inside is expelled to the outside through the air passage. Therefore, water pressure has minimal impact on the pressing force, resulting in smooth pressing. When the push rod is in the second position, water flows sequentially through the first inlet, the second inlet, the second water distribution channel, and the second overflow outlet, finally entering the second outlet, thus switching the water path. At this point, under water pressure, the push rod remains essentially stationary, ensuring continuous water flow from the second outlet. When the user does not need water and turns off the main switch on the inlet pipe, i.e., closes the first inlet, the water pressure inside the main body decreases. The elastic force of the elastic element is sufficient to reset the push rod to the first position. During this process, the volume of the air chamber increases, and outside air enters the air chamber through the air passage, allowing the push rod to move smoothly and complete the reset. Therefore, each time the main switch is turned off, the water distribution device can connect the default water circuit, making it convenient for users to remember and effectively reducing the probability of misoperation.

[0013] According to some embodiments of the present invention, the valve body includes an end shell portion and an outer shell portion, the end shell portion being connected to one end of the outer shell portion facing the interior of the main body, and the air cavity being defined between the end shell portion and the end of the push rod.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0046] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0047] Reference Figure 1 and Figure 2As shown, the water distribution device 1000 of one embodiment of the present invention can be used to direct water from a single inlet pipe to different water circuits, such as between an overhead shower and a handheld shower, or between the main faucet and a pull-out faucet in a kitchen sink. This allows the same inlet pipe to supply water to different water circuits as much as possible, improving pipe utilization efficiency and reducing costs and installation complexity. Simultaneously, the push rod 300 of the water distribution device 1000 of this embodiment can automatically reset when the inlet pipe is turned off, ensuring the default water circuit is connected, making it convenient for users to remember.

[0048] Reference Figure 2 and Figure 3 As shown, the water distribution device 1000 of this embodiment includes a main body 100, a valve body 200, a push rod 300, and a spring 500. A water inlet connector 120 is provided above the main body 100, and a first water outlet connector 130 and a second water outlet connector 140 are spaced apart below it. The water inlet connector 120 forms a first water inlet 121, and the first water outlet connector 130 and the second water outlet connector 140 respectively form a first water outlet 131 and a second water outlet 141. The first water outlet connector 130 can be connected to a top-mounted shower head, and the second water outlet connector 140 can be connected to a handheld shower head. The main body 100 also has an installation cavity 110 inside, and an installation port 150 is provided on the right side of the main body 100. The first water inlet 121, the first water outlet 131, the second water outlet 141, and the installation port 150 all communicate with the installation cavity 110. The valve body 200 is a hollow structure and is installed in the mounting cavity 110 through the mounting port 150. The valve body 200 has a second water inlet 220, a first water outlet 230, a second water outlet 240, and a third through hole 262. One end of the push rod 300 is slidably disposed inside the valve body 200, and the other end of the push rod 300 can pass through the third through hole 262 to be exposed in the valve body 200. An air cavity 330 is defined between the push rod 300 and the interior of the valve body 200. The push rod 300 has a first water distribution groove 310 and a second water distribution groove 320 spaced apart along its axial direction. The interior of the push rod 300 also defines an air passage 301, the two ends of which are connected to the air cavity 330 and the external space of the push rod 300, respectively. A spring 500 can be sleeved on the push rod 300 to provide a force for the push rod 300 to move and reset along its axial direction.

[0049] The push rod 300 has a first position and a second position. The push rod 300 can be moved from the first position to the second position by manually pushing it. When water is flowing through the first inlet 121 and the push rod 300 is in the first position, for example... Figure 3 At the position of the push rod 300, water entering from the first inlet 121 can pass through the second inlet 220, the first water distribution channel 310, and the first water outlet 230 in sequence, and finally be discharged from the first outlet 131, resulting in water from the top spray shower.

[0050] When the user needs to hold the showerhead to spray water, pressing the push rod 300 overcomes the spring force of the spring 500, causing the push rod 300 to switch to the second position, for example... Figure 4 The location is shown in the figure. During the pressing process, the air cavity 330 is compressed by the push rod 300, reducing its volume. The air inside the air cavity 330 is then discharged to the outside through the air passage 301, for example... Figure 5 As indicated by the arrow in the diagram. Therefore, water pressure has little effect on the pressing force, resulting in smooth pressing. At this time, water passes sequentially through the first inlet 121, the second inlet 220, the second water distribution channel 320, and the second outlet 240, finally exiting from the second outlet 141, allowing water to flow from the handheld shower head. Under the action of water pressure, the push rod 300 can remain in the second position.

[0051] When the user does not need water, that is, when the first water inlet 121 is turned off, the water pressure inside the main body 100 decreases, and the elastic force of the spring 500 is sufficient to reset the push rod 300 to the first position. During this process, the volume of the air chamber 330 increases, and outside air enters the air chamber 330 through the air passage 301. Even if the overhead shower and hand shower are equipped with check valves, the push rod 300 can still be successfully reset to the first position, thereby connecting the default water circuit of the overhead shower. When the first water inlet 121 is opened again, the overhead shower will spray water, which is convenient for the user to remember and effectively reduces the probability of misoperation.

[0052] Reference Figure 3 and Figure 6 As shown, in an embodiment of the present invention, the valve body 200 includes an end shell portion 250 and an outer shell portion 260, with the end shell portion 250 connected to the end of the outer shell portion 260 facing the interior of the main body 100. The connection method can be a detachable connection, such as a screw connection, or the end shell portion 250 having external threads and the outer shell portion 260 having internal threads, with the end shell portion 250 and the outer shell portion 260 connected by threads. It is understood that the detachable connection of the end shell portion 250 and the outer shell portion 260 facilitates the installation of the push rod 300 inside the valve body 200, and makes subsequent cleaning or replacement of the push rod 300 easier. In another embodiment of the present invention, the end shell portion 250 and the outer shell portion 260 can be integrally formed, with one end of the end shell portion 250 having a through hole, through which the push rod 300 is installed inside the valve body 200, and the through hole is subsequently sealed with a sealing plug.

[0053] Continue to refer to Figure 3 and Figure 6 As shown, in an embodiment of the present invention, an air cavity 330 is defined between the end housing 250 and the left end of the push rod 300, so that the push rod 300 moves along... Figure 3When the push rod moves left or right, the size of the air cavity 330 can change, allowing the air inside the air cavity 330 to be discharged to the outside along the air passage 301 of the push rod 300. Therefore, the pressing of the push rod 300 is less affected by water pressure and the pressing is smooth. In order to improve the sealing between the left end of the push rod 300 and the end shell 250, a sealing ring is provided at the left end of the push rod 300 to allow the push rod 300 and the end shell 250 to slide and seal, effectively reducing the possibility of water entering the air cavity 330. For example, the left end of the push rod 300 is provided with a third annular protrusion 350, and the outer peripheral wall of the third annular protrusion 350 is provided with an annular groove (not shown in the figure). The sealing ring is fitted in the annular groove and can abut against the inner wall surface of the end shell 250 to seal the air cavity 330.

[0054] Reference Figure 6 As shown in the embodiment of the present invention, the valve body 200 is provided with a first annular protrusion 263 and a second annular protrusion 264 spaced apart. A second water inlet 220 is provided between the first annular protrusion 263 and the second annular protrusion 264. The second water inlet 220 is connected to the first water inlet 121. The first annular protrusion 263 and the second annular protrusion 264 are sealed to the inner wall of the main body 100, thereby improving the sealing performance between the valve body 200 and the main body 100.

[0055] Continue to refer to Figure 6 As shown in the embodiment of the present invention, the first annular protrusion 263 and the second annular protrusion 264 can be disposed on the outer shell portion 260. The first annular protrusion 263 and the second annular protrusion 264 are sealed and fitted with the main body 100 and are located on both sides of the first water inlet 121. For example, the main body 100 extends inward on both sides of the first water inlet 121 to form two protrusions. The first annular protrusion 263 and the second annular protrusion 264 are both fitted with sealing rings. The sealing rings and the two protrusions are sealed and connected, so that water flows from the first water inlet 121 through the second water inlet 220, and then enters the first water distribution groove 310 or the second water distribution groove 320 according to the position of the push rod 300. This effectively prevents water from directly seeping into the mounting cavity 110 from between the inner wall of the main body 100 and the outer wall of the valve body 200 after entering the first water inlet 121, thus preventing water leakage. Therefore, by setting the first annular protrusion 263 and the second annular protrusion 264, the sealing performance between the valve body 200 and the main body 100 can be improved, reducing the possibility of water seepage and leakage.

[0056] Continue to refer to Figure 6As shown, in an embodiment of the present invention, the second annular protrusion 264 has a second water inlet 240 on the side opposite to the first annular protrusion 263. The first annular protrusion 263 has a first through hole 261 on the side opposite to the second annular protrusion 264, and the end shell portion 250 has a second through hole 251. A first water inlet 230 is formed between the first through hole 261 and the second through hole 251. That is, when the push rod 300 is in the first position, the water entering from the first water inlet 121 can pass through the second water inlet 220, the second through hole 251, and the first through hole 261 in sequence, and finally enter the mounting cavity 110, and then be discharged from the first water outlet 131.

[0057] Reference Figure 7 As shown in the embodiment of the present invention, the push rod 300 is provided with a third annular protrusion 350, a fourth annular protrusion 360, and a fifth annular protrusion 370, which are slidably sealed to the valve body 200 along its axial direction. A first water-dividing groove 310 is formed between the third annular protrusion 350 and the fourth annular protrusion 360, and a second water-dividing groove 320 is formed between the fourth annular protrusion 360 and the fifth annular protrusion 370. Each of the third annular protrusion 350, the fourth annular protrusion 360, and the fifth annular protrusion 370 is fitted with a sealing ring to allow the third annular protrusion 350, the fourth annular protrusion 360, and the fifth annular protrusion 370 to slide and seal against the inner wall of the valve body 200, thereby improving the waterproof effect.

[0058] Reference Figure 4 As shown in the embodiment of the present invention, the inner wall of the valve body 200 protrudes inward to form a limiting portion 211. The limiting portion 211 can abut against the fifth annular protrusion 370, thereby limiting the position of the push rod 300 when it moves from left to right and preventing the push rod 300 from sliding excessively. When the push rod 300 moves from right to left, the left end of the push rod 300 can abut against the end shell portion 250 for limiting. Therefore, the structural design of the valve body 200 and the push rod 300 is reasonable and has high reliability.

[0059] Reference Figure 2 and Figure 3 As shown in the embodiment of the present invention, the water distribution device 1000 further includes a button 400, which is connected to one end of the push rod 300 exposed in the valve body 200, that is, the right end of the push rod 300. The connection method can be fixed by screws, or: the inner side of the button 400 is provided with an annular portion 410, the annular portion 410 is provided with an internal thread, the right end of the push rod 300 is provided with an external thread, and the internal thread and the external thread of the button 400 are threadedly connected, so that the button 400 is fixedly connected to the push rod 300. Therefore, the push rod 300 can be moved by pressing the button 400 to realize the switching of the water path, which is simple and convenient to operate.

[0060] Reference Figure 3 and Figure 6As shown in the embodiment of the present invention, the valve body 200 has a positioning groove 265 at one end facing the button 400, and the positioning groove 265 may be annular. A spring 500 is sleeved on the push rod 300, with one end of the spring 500 located in the positioning groove 265 and the other end abutting against the button 400. Therefore, when the button 400 is pressed, the push rod 300 moves under the elastic force provided by the spring 500. When the first water inlet 121 is closed, the water pressure decreases, and the button 400, under the action of the elastic force, drives the push rod 300 to reset. The structure is simple and the operation is reliable. It should be noted that the spring 500 is an elastic element, and elastic elements can also be elastic parts such as silicone or rubber.

[0061] Referring to Figure 3, in an embodiment of the present invention, the button 400 is provided with an air vent 420, which is connected to the air passage 301. Therefore, air in the air passage 301 is discharged to the outside through the air vent 420, and outside air can also enter the air passage 301 through the air vent 420 and then enter the air cavity 330. The air passage 301 can be arranged along the axis of the push rod 300, extending through the push rod 300, and the air vent 420 and the air passage 301 are coaxially arranged. This arrangement is simple and convenient to manufacture, and has high production efficiency. Alternatively, in some embodiments of the present invention, the end of the air passage 301 near the button 400 can also be connected to the outside through an opening in the side wall of the push rod 300. In this case, the button 400 may not have an air vent 420; the appropriate solution can be selected based on the actual situation.

[0062] Reference Figure 1 and Figure 2 As shown in the embodiment of the present invention, the water distribution device 1000 further includes a ring-shaped decorative sleeve 600, which is connected to the main body 100, and the button 400 is disposed inside the decorative sleeve 600. The decorative sleeve 600 serves a decorative function, improving the aesthetics and overall appearance of the water distribution device 1000. The decorative sleeve 600 and the main body 100 can be connected by a threaded connection or a snap-fit ​​connection. For example, when using a snap-fit ​​connection, one end of the decorative sleeve 600 has multiple first snaps 610 spaced apart and surrounding the inner side of the decorative sleeve 600, and one side of the main body 100 has multiple second snaps 160 spaced apart and surrounding the mounting opening 150. The multiple first snaps 610 and the multiple second snaps 160 snap together, thereby connecting the decorative sleeve 600 and the main body 100, making the installation process simple and convenient.

[0063] Reference Figure 1 As shown in the embodiment of the present invention, the water distribution device 1000 further includes a first connecting pipe 170 and a second connecting pipe 180. One end of the first connecting pipe 170 and the second connecting pipe 180 are respectively connected to the first water outlet connector 130 and the second water outlet connector 140, and the other end of the first connecting pipe 170 and the second connecting pipe 180 can be respectively connected to the overhead shower head and the handheld shower head.

[0064] Reference Figure 8 As shown, one embodiment of the water distribution component of the present invention includes the water distribution device 1000 of the above embodiments. Multiple water distribution devices 1000 are provided, for example, two. The first connecting pipe 170 of one water distribution device 1000 is connected to the inlet connector 120 of the other water distribution device 1000 to expand more water channels. Three water distribution devices 1000 may also be provided, with the first connecting pipe 170 and the second connecting pipe 180 of one water distribution device 1000 respectively connected to the inlet connectors 120 of the other two water distribution devices 1000. Therefore, with a modular design, users can easily expand the water channels according to their own needs, and the water distribution device 1000 has high versatility.

[0065] Since the water distribution component adopts all the technical solutions of the water distribution device 1000 in the above embodiments, it has at least all the beneficial effects brought about by the technical solutions in the above embodiments, which will not be repeated here.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
