Detailed Description

While the disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the drawings and detailed description thereto are not intended to limit the disclosure to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims. The figures are for illustration and are not drawn to scale.

The use of the terms first, second, etc. in this description is not intended to distinguish between different components, but rather to rank or indicate importance or primary-secondary relationship.

As shown in fig. 1, a pipe valve for closing and/or switching according to an embodiment of the present invention includes a valve body, an inlet, an outlet, a water stopping member, a plugging assembly, a switching assembly, and the like. In this example, the valve body includes an upper cover 21, an upper valve body 215, and a lower valve body 25 that cooperate with one another. In one example, the upper valve body 215 and the lower valve body 25 are connected by a securing member, such as a bolt 214.

Referring to fig. 2 and 3, the right end of the lower valve body 25 is provided as an inlet 251. Accordingly, a first outlet 252 and a second outlet 253 are sequentially provided at the left end of the lower valve body 25, and the first outlet 252 and the second outlet 253 are respectively communicated with a water containing chamber (to be described in detail later) of the valve body. It should be noted that, in the present example, the design concept of the present invention is illustrated by taking one inlet and two outlets as an example, but it is understood that those skilled in the art can set the number of them according to actual needs, and is not limited to the illustrated example herein.

As shown in fig. 1 to 3, corresponding to the first outlet 252 and the second outlet 253, a first outlet chamber 254 and a second outlet chamber 255 are provided on the middle portion of the lower valve body 25, and an inlet chamber 256 is provided on the peripheral portion of the lower valve body, and the first outlet chamber 254 and the second outlet chamber 255 are closed by the water stop member 26 and the blocking member which are engaged with each other. The inlet 251 is in turn connected to the inlet chamber 256 of the lower valve body 25 and a water receiving chamber (described in detail below) of the valve body, and is connected to or disconnected from the first outlet chamber 254 and the second outlet chamber 255 via the water stop member 26.

An upper valve body 215 and an upper cover body 21 are sequentially arranged above the water stopping member 26, and a space between the upper valve body 215 and the water stopping member 26 is a water containing cavity 261. The water containing cavity 261 is also sealed via the upper valve body 215, the blocking assembly and the water stopping member 26, i.e. the water containing cavity 261 is sealed by the upper valve body 215 and the blocking assembly (e.g. from above) closing the water stopping member 26, thereby achieving communication or blocking of the water stopping member 26 with the first outlet cavity 254 and the second outlet cavity 255, and communication or blocking with the inlet cavity 256.

In fact, the purpose of providing the water stop member 26 in the cavity of the valve body is mainly to prevent the direct communication between the inlet 251 and the first outlet 252 and the second outlet 253, so that the selective communication therebetween can be achieved by the switching assembly described later.

The switching member is configured to cause the blocking member to block the corresponding water passage holes 262, 263 of the water stopping member 26 by rotation thereof, thereby enabling to close the communication between the inlet 251 and the first outlet 252 and the second outlet 253 and/or to perform switching between the first outlet 252 and the second outlet 253.

To effect closure or switching between the first outlet 252 and the second outlet 253, the water passage holes in the water stop member 26 include a first water passage hole 262 communicating with the first water outlet chamber 254 when fitted into the valve body and a second water passage hole 263 communicating with the second water outlet chamber 255. It will be appreciated that the number of water passage holes in the water stop member 26 is typically set to correspond to the number of outlet chambers, and the size of the water passage holes may be selected according to the actual requirements.

In addition, referring specifically to fig. 8, the water stopping member 26 is provided with at least one overflow hole 264 (as shown, two overflow holes 264 are shown) in addition to the first and second

water passing holes

262 and 263 so as to achieve communication between the water inlet chamber 256 and the water containing chamber 261.

In one example, the water stop member 26 is a water stop pad made of an elastic material, and includes a body and a first water stop flange portion 265 and a second water stop flange portion 266 provided on the body, the first water stop flange portion 265 being provided corresponding to the first water outlet chamber 254 and the second water stop flange portion 266 being provided corresponding to the second water outlet chamber 255, and the first water passage hole 262 being located on an area surrounded by the first water stop flange 265 portion and the second water passage hole 263 being located on an area surrounded by the second water stop flange portion 266. As shown in fig. 1 and 8, at least a part of the first and second water

stop flange portions

265 and 266 is received in the water stop rib 257 (see fig. 3) of the lower valve body 25 to achieve that the respective first and/or second water

stop flange portions

265 and 266 are pushed upward when the water stop member 26 receives a large water pressure from the

water outlet chambers

254, 255. And simultaneously when the first water stop flange part 265 and/or the second water stop flange part 266 is matched with the water stop rib 257 on the lower valve body 25, the corresponding first water outlet cavity 254 and/or the second water outlet cavity 255 are sealed.

The sizes of the first and second water stop flange portions and the numbers and sizes of the first and second receiving holes may be selected according to actual needs.

In addition, referring to fig. 8, an installation positioning hole (not shown) may be further provided on the body in a region other than the region surrounded by the first water stop flange portion 265 and the second water stop flange portion 266, so as to facilitate installation positioning, and will not be discussed in detail herein.

As shown in fig. 1, the switching assembly includes the switching shaft 212, the first spring 211, the rotating disk 24, the guide shaft 22, the second spring 23, the third spring 213, and the button 216. As shown in fig. 3, the upper valve body 215 is provided with a first receiving hole 215a and a second receiving hole 215b for receiving the corresponding blocking members, and the first receiving hole 215a and the first water passage hole 262 and the second receiving hole 215b of the water stopping member 26 are provided in correspondence with each other and the second water passage hole 263 of the water stopping member 26. A space between the upper valve body 215 and the water stopping member 26 corresponding to the first receiving hole 215a and the second receiving hole 215b is the water receiving chamber.

It should be noted that the number, shape and size of the receiving holes may be designed as required. It is preferable that the number, shape and size of the accommodating holes are the same as those of the water passage holes in the water stop member.

In order to install the switching assembly in the valve body, each of the upper valve body 215, the lower valve body 25 and the water stopping member 26 is provided with a guide groove at the center (as shown in fig. 3, each of them is provided with a guide groove, and here, for the sake of simplicity of illustration, only the corresponding guide groove 258 and guide groove 267 (see fig. 8) are shown on the lower valve body 25 and the water stopping member 26, respectively).

The button 216 is received in a receiving groove (not shown) on the lower valve body 25; one end of the switching shaft 212 is inserted through a guide groove 258 (see fig. 3) of the lower valve body 25 and then connected to the button after being inserted into a third spring 213 (it should be noted that the third spring 213 may be omitted and does not affect the operation of the button 216), and the other end of the switching shaft 212 having a switching shaft inclined tooth 212a (shown in fig. 7A) is positioned in the guide groove 258 of the lower valve body to allow the switching shaft 212 to move along the guide groove 258 of the lower valve body.

Referring to fig. 7B and 7C, a lower valve body helical tooth 258a is disposed in the guide groove 258 of the lower valve body, the lower valve body helical tooth 258a is engaged with the switching shaft rib 212B, and the switching shaft helical tooth 212a is located on the switching shaft rib 212B on the switching shaft 212.

Referring to fig. 3 and 9, the rotary disk 24 has a rotary disk rib 241 and rotary disk helical teeth 242 on the rotary disk rib, the rotary disk rib 241 is located in the guide grooves of the upper valve body 215 and the lower valve body 25 and moves along the guide grooves of the upper valve body 215 and the lower valve body 25, wherein one end of the guide groove 258 of the lower valve body, which is away from the button 216, is inserted into the guide groove of the upper valve body 215.

As shown in fig. 1 and 3, the guide shaft 22 is provided at one end with a first spring 211 and is accommodated in the inner cavity of the switching shaft 212, and the other end of the guide shaft 22 passes through a center hole 243 (see fig. 9) of the rotating disk 24 and a second spring 23 above the rotating disk and is then mounted on the shaft seat 201 at the top of the upper cover 21.

When the button 216 is pressed, the button 216 pushes the switching shaft 212 to move upward, the switching shaft 212 pushes the rotating disc 24 to move upward, and after the rotating disc ribs 241 leave the guide grooves 258 of the lower valve body 25, the switching shaft helical teeth 212a and the rotating disc helical teeth 242 cooperate with each other to rotate the rotating disc by a first predetermined angle (e.g., 90 °).

Thereafter, when the push button 216 is released, the switching shaft 212 and the push button 216 are reset to the original state by the elastic force of the first spring 211, the rotating disk helical teeth 242 and the lower valve body helical teeth 258a are engaged, the rotating disk 24 is driven to rotate by a second predetermined angle (e.g., 90 °) by the elastic force of the second spring 23, the rotating disk ribs 241 slide into the guide grooves 258 of the lower valve body, and move along the guide grooves 258 of the lower valve body until the switching hole (to be described in detail later) of the rotating disk selectively receives the blocking member (to be described in detail later) in the first receiving hole 215a and the second receiving hole 215 b.

As described above, the rotary disk 24 is located above the upper valve body 215, and three switching holes 244 are provided on the rotary disk 24, which are located on the same circumference centering on the center hole 243 of the rotary disk, are adjacent to each other, and are spaced apart by 90 °. The three switching holes 244 selectively release or block a blocking member (to be described later) located in any one of the first and

second accommodation holes

215a and 215b according to the rotation of the rotating disk.

In this example, three switching holes are taken as an example to illustrate the design concept of the present invention, but it is understood that those skilled in the art can set the number of them according to the actual requirement, for example, the switching holes can be designed to be 1 or 2 (as shown in fig. 9), and are not limited to the example here.

As shown in fig. 1 to fig. 3, the first receiving hole 215a and the second receiving hole 215b of the upper valve body 215 are both provided with a plugging member, and the structure and function of the plugging member in the first receiving hole 215a are the same as those of the second receiving hole 215b, and the structure and function of the first receiving hole 215a are the same as those of the second receiving hole 215b, so that only the first receiving hole 215a and the plugging member therein are taken as an example, and the second receiving hole 215b and the plugging member therein are not repeated herein.

The number, shape and size of the plugging members correspond to those of the receiving holes of the upper valve body, and the plugging members may be movable up and down in the receiving holes and may seal the receiving holes.

The blocking assembly includes a seal shaft 29 passing through the first receiving hole 215a, a seal body 210 at a first end of the seal shaft 29, a seal ring 28 at a second end of the seal shaft 29, and a spring 27 on the seal shaft 29. The first and second ends of the seal shaft 29 are opposite ends of the seal shaft 29.

An annular projection 215c is provided in the first accommodation hole 215a of the upper valve body 215, one end of the seal shaft 29 connected to the seal body 210 is provided with a projection 291, the projection 291 projects outwardly below the projection 215c to at least partially abut against the projection 215c, and the seal ring 28 and the spring 27 are provided in this order on a side of the projection 215c facing away from the projection 291.

A groove is formed at the center of the first end of the sealing shaft 29, and a protrusion 210a is formed at the middle portion of the sealing body 210, so that the cross-section of the sealing body 210 is substantially in a shape of a Chinese character 'shan'. The projection 210a is accommodated in the groove, and the peripheral edge portion of the sealing body 210 surrounds the projection 291 and is flush with the surface of the projection 291, that is, the surface of the projection 291 on the side close to the projection 215c is flush with the projections on both sides of the sealing body 210 shaped like a Chinese character 'shan'.

It should be noted that the seal shaft 29 and the seal body 210 may be two independent members as shown in fig. 10A, or may be an integrally formed component as shown in fig. 10B, and those skilled in the art may select them as needed.

A stepped bore is provided in the centre of the seal ring 28 and a stepped nose portion 292 is provided at the second end of the seal shaft, the nose portion 292 fitting into the bore of the seal ring 28. It will be appreciated by those skilled in the art that the bore of the seal ring 28 may also be provided with 2, 3 steps and correspondingly the nose portion of the second end of the seal shaft may also be provided with 2, 3 steps. The skilled person can make corresponding selections as required.

When the blocking component only blocks the first water through hole 262, the fluid entering the water inlet cavity 256 from the inlet 251 flows into the second water outlet cavity 255 through the gap between the water stopping member 26 and the lower valve body 25 and cannot flow into the first water outlet cavity 254, so the fluid can only flow out from the second outlet 253, at this time, because the fluid flows into the water containing cavity 261 from the overflow hole 264 on the water stopping member, a pressure difference exists between the first water outlet cavity 254 and the water containing cavity 261, and the water stopping rib 257 corresponding to the first water outlet cavity 254 on the water stopping member 26 and the lower valve body 25 is sealed.

Of course, when the blocking assembly blocks only the second through hole 263, the fluid entering the inlet cavity 256 from the inlet 251 flows into the first outlet cavity 254 via the gap between the water stopping member 26 and the lower valve body 25, but cannot flow into the second outlet cavity 25, and therefore only can flow out from the first outlet 252, at this time, because the fluid flows into the water containing cavity 261 from the overflow hole 264 on the water stopping member 26, there is a pressure difference between the second outlet cavity 255 and the water containing cavity 261, so that the water stopping rib 257 corresponding to the second outlet cavity 255 on the water stopping member 26 and the lower valve body 25 is sealed.

It should be noted that the present invention is described with water as an example of the fluid, and the working principle of the pipe valve of the present invention is also described.

The switching principle of the present invention will be described below with reference to fig. 2-5 in conjunction with different states of the pipe valve.

State one is referred to as the initial state, i.e., the state in which only the first outlet 252 is out of water; state two is a state in which both the first outlet 252 and the second outlet 253 are out of water after the button 216 is pressed once; state three is a state in which only the second outlet 253 is out of water after the button 216 is pressed once again (with respect to the initial state in which the button 216 is pressed twice); state four is a state in which both the first outlet 252 and the second outlet 253 are out of water after the button is pressed once again (three times with respect to the initial state button 216).

Specifically, referring to fig. 3, the blocking member in the first accommodation hole 215a is accommodated in the switching hole 244 of the rotating disk 24 such that the blocking member is separated from the first water passage hole 262, whereby the first water passage hole 262 is not blocked by the blocking member. After entering the inlet chamber 256, the water flushes the first sealing lip 265 into the first outlet chamber 254, resulting in the first outlet 252 being discharged.

And since the plugging member in the second receiving hole 215b is blocked by the main body of the rotating disk 24 so that the plugging member plugs the second through hole 263, the second water-stop flange portion 266 contacts the water-stop rib 257 on the lower valve body 25, and water enters the water-containing chamber 261 through the water-overflow holes 264 on the water-stop member 26 at the peripheries of the first water-stop flange portion 265 and the second water-stop flange portion 266. At this time, the water receiving area of the upper surface of the second water stop flange portion 266 is larger than the water receiving area of the lower surface thereof, so that a water pressure difference is generated, and the second water stop flange portion 266 and the water stop rib 257 of the lower valve body 25 are tightly sealed by the water pressure difference, so that water cannot enter the second water outlet chamber 255, and thus water cannot be discharged from the second outlet 253.

As shown in the top right view of fig. 3, the rotary plate 24 is located at a downward position in the page, and the switching hole thereof just receives the blocking member in the first receiving hole 215 a.

Referring to fig. 1, 2 and 3, the switching shaft rib 212b is placed in the guide groove 258 of the lower valve body and moves along the guide groove 258 of the lower valve body.

The switching shaft helical teeth 212a and the rotating disc helical teeth 242 are engaged, and the rotating disc ribs 241 are placed in the guide grooves 258 of the lower valve body and move along the guide grooves 258 of the lower valve body.

Referring to fig. 4, when the button 216 is pressed, the button 216 pushes the switching shaft 212 to move vertically upward, the switching shaft 212 pushes the rotary plate 24 to move vertically upward, and when the rotary plate rib 241 leaves the guide groove 258 of the lower valve body, the combination of the switching shaft helical tooth 212a and the rotary plate helical tooth 242 drives the rotary plate 24 to rotate by a certain angle (e.g., 90 °), at which the rotary plate 24 is rotated by 90 ° to the left with respect to the position shown in fig. 3 in the corresponding top view.

Referring to fig. 4, after the button 216 is released, the switching shaft 212 and the button 216 are reset to the original state by the elastic force of the first spring 211. The rotating disk helical teeth 242 and the lower valve body helical teeth 258a are matched, under the action of the elastic force of the second spring 23, the rotating disk 24 is driven to rotate by a certain angle (for example, 90 °), the rotating disk ribs 241 slide into the guide grooves 258 of the lower valve body and move along the guide grooves 258 until two of the switching holes 244 on the rotating disk 24 respectively accommodate the blocking components in the first accommodating hole 215a and the second accommodating hole 215b on the water stopping member 26 (that is, the switching hole 244 on the rotating disk 24 is rotated by 90 ° to the left in the corresponding page of the top view in fig. 3).

At this time, the first water passage hole 262 is not closed, and after water enters the water inlet chamber 256, the water flushes the first water stop flange portion 265 and enters the first water outlet chamber 254, and the first outlet 252 is discharged. Similarly, the second through hole 263 is not blocked, and after the water enters the water inlet cavity 256, the water flushes the second water stop flange portion 266 and enters the second water outlet cavity 255, so that the second outlet 253 also outputs the water.

Referring to fig. 5, the button 216 is pressed again (the button 216 is pressed a second time), thereby causing the switching hole 244 (shown in conjunction with fig. 9) on the rotary disk 24 to rotate 90 ° again, so that the switching hole 244 just receives the blocking member in the second receiving hole 215b, so that the second through-hole 263 is not blocked. Similar to the initial state, this will result in water passing through the second outlet chamber 255 and causing the second outlet 253 to be drained, while the first outlet 252 will not be drained.

Referring to fig. 6, the button 216 is pressed again (the button 216 is pressed for the third time), causing the switching hole 244 on the rotating disk 24 to rotate again by 90 °, so that the oppositely disposed two switching holes 244 just receive the plugging assemblies in the first receiving hole 215a and the second receiving hole 215b, respectively, on the water stopping member 26.

Similarly to the second state, at this time, since the switching hole 244 does not block the first and second water passage holes 262 and 263, both the first and

second outlets

252 and 253 discharge water.

It should be noted that, in the embodiment of the present invention, the water stop pad is provided with a first water stop flange portion at a portion corresponding to the first water outlet cavity and a second water stop flange portion at a portion corresponding to the second water outlet cavity, the first water passage hole is located in an area surrounded by the first water stop flange portion, and the second water passage hole is located in an area surrounded by the second water stop flange portion. However, it is also possible to provide the water receiving holes or the plurality of protrusions at other angles as needed to achieve that in a certain state, neither the first outlet nor the second outlet discharges water. In view of these, all can be obtained without any inventive effort based on the disclosure of the present invention, and thus will not be discussed in detail here.

Specifically, as shown in connection with fig. 9, the left drawing shows that the rotary disk 24 is provided with three adjacent accommodation holes which are located on substantially the same circumference of the rotary disk 24 and are spaced from each other by an angle of about 90 degrees. By rotation of the rotary disc 24 and cooperation with the plugging assembly, it is possible to achieve water outlet from a single outlet of the two outlets of the pipe valve, mixed water outlet from the two outlets, mixed water outlet from the other single outlet of the two outlets, and mixed water outlet from the two outlets, as described above.

In one example, when the pipe valve is used for a shower head, one of the outlets may be set as massage water, the other outlet may be set as shower water, and the mixed water is a case where the shower water and the massage water flow out simultaneously.

In the middle view of fig. 9, which shows another alternative example of the present invention, it is also possible to provide two adjacent receiving holes on the rotary disk 24, which are located on substantially the same circumference of the rotary disk 24 and are spaced apart from each other by an angle of approximately 90 degrees. By rotating the rotary disk 24 and cooperating with the closure assembly, it is possible to achieve that only one of the outlets always discharges water without mixed water.

The right-hand side view in fig. 9 shows a further alternative example of the invention, it being possible for 1 receiving opening to be provided in the rotary disk 24, which opening is located on the circumference of the rotary disk 24. The following sequence of running water can be achieved by rotation of the rotating disk 24 and cooperation with the plugging assembly: one of the two water outlets discharges water; the two water outlets do not discharge water; the other water outlet of the two water outlets discharges water; and water does not flow out of the two water outlets. The adjustment of the two outlet water outlet conditions can be adjusted by setting the number of the receiving holes on the rotating disk 24 according to the needs through the above exemplary description.

According to the utility model discloses a pipeline valve for closing and/or switching, through the cooperation with the stagnant water component with the help of switching subassembly, can realize the switching of the state of going out water between first export and/or the second export through exerting less power.
