Description

Switch valve core, tap and shower post assembly

Technical Field

The utility model relates to a switching valve core for simultaneously supporting upper water outlet and lower water outlet and a faucet comprising the switching valve core. The utility model also relates to a shower post assembly comprising the switching valve core.

Background

Currently, the commercially available switching valve core mostly adopts a bottom-in bottom-out mode or a middle bottom-in bottom-out mode to realize the switching of the water channel. When the switching valve core is installed on a shower product, because a flow path which is sprayed from the water outlet part of the switching valve core upwards to the top needs to be provided, a water outlet communication channel from the switching valve core to a shower rod needs to be additionally arranged. This complicates the construction of the entire shower faucet.

It is therefore desirable to provide a new switching valve cartridge for shower-like products which is expected to allow the structure of the shower-like product to be simplified, to be easily installed and to allow the production costs to be reduced.

SUMMERY OF THE UTILITY MODEL

The utility model is based on the following tasks: a shower-like product is proposed which, compared to the prior art mentioned above, allows to simplify the structure of the shower-like product, to reduce the number of components and, ultimately, to reduce the production costs.

This task is solved by a switch cartridge, a faucet and a shower post assembly according to the present invention.

The switching spool according to the present invention includes:

-a valve core water inlet,

-at least one outlet port on the cartridge,

at least one lower cartridge outlet arranged in the valve seat opposite the upper cartridge outlet in the longitudinal direction,

-a stationary vane fixed to the valve seat, the stationary vane comprising at least one stationary vane water outlet extending therethrough in a longitudinal direction, and a groove extending in a circumferential direction, the groove being circumferentially spaced from the at least one stationary vane water outlet;

the valve element comprises a valve element inlet, a valve element outlet, a valve element inlet, a valve element outlet and a valve element outlet.

In the switching valve core according to the utility model, the movable valve plate can rotate relative to the fixed valve plate.

In the first rotation position, the water inlet part of the movable valve plate is in fluid communication with the groove in the fixed valve plate, the groove is in fluid communication with the water outlet of the movable valve plate, and the water outlet of the movable valve plate is in fluid communication with the water outlet on the valve core, so that water from the water inlet of the valve core flows into the groove in the fixed valve plate through the water inlet part of the movable valve plate, flows to the water outlet of the movable valve plate through a cavity formed by the matching of the groove and the lower surface of the movable valve plate above the fixed valve plate, and finally flows out of the switching valve core through the water outlet on the valve core. When the switch valve cartridge according to the present invention is used in a shower column assembly having a top spray, the water outlet on the valve cartridge may be in fluid communication with the top spray through, for example, a fluid passage provided in the rotating shaft, thereby causing water exiting the switch valve cartridge in an upward direction to flow toward the top spray.

Optionally, a channel extending obliquely upwards from the lower surface of the movable valve plate is further provided in the movable valve plate, and in the first rotation position, the groove in the fixed valve plate is in fluid communication with the movable valve plate water outlet through the channel.

In a second rotation position different from the first rotation position, the water inlet part of the movable valve plate is in fluid communication with one water outlet of the fixed valve plate in the fixed valve plate, and the water outlet of the fixed valve plate is in fluid communication with a lower water outlet of the valve core, so that water from the water inlet of the valve core flows through the water outlet of the fixed valve plate through the water inlet part of the movable valve plate and finally flows downwards through the lower water outlet of the valve core to leave the switching valve core.

Therefore, the switching valve core can support at least two water outlet modes of upper water outlet and lower water outlet by rotating the movable valve plate relative to the fixed valve plate. In particular, in the switching valve core, by means of a cavity formed by matching a circumferential groove arranged in a fixed valve plate and the lower surface of a movable valve plate, the switching valve core can directly provide an upward water outlet flow path required by upward water outlet, and linear switching for completing flow path adjustment along one direction is realized. Compared with the prior art, a connecting pipe for switching the valve core to the flow path of the shower rod is not required to be provided, so that the structure of a product such as a shower column including the switching valve core of the utility model can be simplified, the installation space can be saved, and the switching operation is simple and convenient.

In one embodiment of the switching valve cartridge according to the utility model, the switching valve cartridge comprises a rotary shaft, to which the movable valve plate is fixedly connected, for example by form fit. The rotating shaft is configured to have a hollow cavity. The water outlet of the movable valve plate is connected with the hollow cavity and is communicated with the water outlet on the valve core through the hollow cavity. The water outlet on the valve core is further communicated with the top sprinkling fluid.

Preferably, in the switching valve core according to the utility model, different numbers of water outlets can be arranged on the fixed valve plate and the movable valve plate according to the water outlet requirement.

In particular, in one embodiment, the switching spool comprises a first spool lower outlet and a second spool lower outlet, and the fixed valve plate comprises a first fixed valve plate outlet and a second fixed valve plate outlet. The first fixed valve plate water outlet, the second fixed valve plate water outlet and the groove are mutually spaced along the circumferential direction. When the movable valve plate rotates to a second rotation position relative to the fixed valve plate, the water inlet part of the movable valve plate and the water outlet of the first fixed valve plate are communicated with the water outlet under the first valve core through fluid, and when the movable valve plate rotates to a third rotation position different from the first rotation position and the second rotation position relative to the fixed valve plate, the water inlet part of the movable valve plate, the water outlet of the second fixed valve plate and the water outlet under the second valve core are communicated with the water outlet under the second valve core through fluid, and at the moment, water from the water inlet of the valve core flows through the switching valve core through the water inlet part of the movable valve plate, the water outlet of the second fixed valve plate and the water outlet under the second valve core.

Through the arrangement of the lower water outlets of the two different valve cores, one-way water outlet and two-way water outlet can be realized by switching the valve cores. When the switching valve core is used for a shower column assembly, one of the lower water outlet of the first valve core and the lower water outlet of the second valve core can be directly communicated with the water outlet part of a lower faucet of the shower column assembly, and the other one can be further connected to a hand-held shower head for example by a hose.

In a preferred embodiment of the switching valve cartridge according to the utility model, the moving valve plate water inlet portion of the moving valve plate comprises a flow guide. Particularly preferably, the flow guide is configured in the shape of a trumpet, extends in the longitudinal direction and extends inwards in the radial direction, i.e. away from the peripheral edge of the movable valve plate. The flared configuration helps to improve the efficiency of guiding the water flow into the moving valve plate, achieving a guiding path that is less obstructive to the water flow.

In one embodiment of the switching valve cartridge according to the utility model, the recess in the stationary plate is of oval configuration. Alternatively, the recess can also be designed in a crescent or rectangular manner, as required. Therefore, the groove is matched with the lower surface of the movable valve plate to form an oval, crescent or rectangular special-shaped cavity.

Preferably, the depth of the recess in the stator plate varies, for example comprising at least a first depth and a second depth. The varying depth of the groove provides a dampening effect for the water flow into the shaped cavity and also serves as a reservoir.

It is particularly preferred that the depth of the groove varies continuously from a first depth at one end of the groove to a second depth at the other end of the groove.

Alternatively, the groove may have at least a first portion with a constant depth and a second portion with a depth varying between the first depth and the second depth.

In addition, the utility model also provides a faucet, which comprises the switching valve core according to any one of the above aspects.

In addition, the utility model also provides a shower column assembly which at least comprises a faucet, a top sprinkler and the switching valve core according to any one of the schemes. The upper water outlet of the valve core of the switching valve core is communicated with the top sprinkling fluid, and the lower water outlet of one valve core of the switching valve core is communicated with the water outlet part of the tap.

Turning now to fig. 3A-5B, various embodiments of the stationary plates 50, 50', 50 "of the switching spool 100 will be further described.

Fig. 3A-3B illustrate a preferred embodiment of the stationary plate 50. In the illustrated embodiment, the groove 501 of the fixed valve plate 50, the first fixed valve plate water outlet 502, and the second fixed valve plate water outlet 503 are arranged at intervals in the circumferential direction. As shown in fig. 3B, in section III, the depth of the groove 501 varies continuously between D1 at the first end 5011 to D2 at the second end 5012.

In a first rotational position of switching valve spool 100 (explained in more detail below in connection with fig. 7), recess 501 cooperates with the lower surface of movable valve plate 40 to form a cavity that is substantially elliptical in shape and through which water flows.

Fig. 4A-4B illustrate another embodiment of a stationary plate 50', wherein features common to the embodiment shown in fig. 3A-3B are identified with the same reference numerals.

In this embodiment, the two long sides of the groove 501 'are arc sections having two concentric circles, and the shape of the cavity formed by the groove 501' when it is engaged with the lower surface of the movable valve plate 40 is substantially crescent-shaped.

As can be seen in fig. 4B, the groove 501' has two portions of different depths in the section IV-IV. The depth varies continuously from D1 to D2 starting from the first end 5011 ', i.e., the bottom of a portion of the groove 501' is sloped, while in the remaining portion the depth of the groove 501 'remains constant at D2 until the second end 5012'.

Fig. 5A-5B illustrate yet another embodiment of the stationary plate 50 ". In this embodiment, the two long sides of the recess 501 "are straight lines parallel to each other. In the first rotational position, the recess 501 "cooperates with the lower surface of the movable valve plate 40 to form a cavity shaped like a rectangle.

The depth variation of the stationary plate 50 "is similar to the stationary plate 50'. As can be seen in FIG. 5B, in section V-V, the depth of the stationary plate 50 "continuously varies from the first end 5011" first to the second depth D2, and then remains constant at D2 until the second end 5012 ".

Fig. 6 shows a perspective view of the movable valve plate 40 of the switching valve cartridge 100 from another angle.

Fig. 6 shows two recesses 403 symmetrically arranged on the outer circumference of the movable valve plate 40 for form-fitting connection with the extensions 203 protruding from the lower end of the rotary shaft 20.

The dynamic valve sheet water inlet portion 401 is configured to extend downward in the longitudinal direction and inwardly form a horn-like shape in the radial direction to optimize a guiding effect of the fluid entering the dynamic valve sheet 40. The flared configuration of the dynamic valve plate water inlet 401 can be clearly seen in the longitudinal sectional views shown in fig. 7 to 9.

The movable valve plate water outlet 402 is configured at the center of the movable valve plate 40.

The switching of the switching valve cartridge 100 between different water outlet modes is explained below with reference to fig. 7 to 9. The flow direction of the water is shown by solid arrows in each of the views in fig. 7 to 9.

As explained above, the movable valve plate 40 can be rotated with respect to the fixed valve plate 50 by actuating the protrusion 301 of the switching handle 30. In the illustrated embodiment of the switching spool 100, the movable valve plate 40 has three rotational positions with respect to the fixed valve plate 50, namely, a first rotational position for the upper water outlet, a second rotational position for the lower water outlet, and a third rotational position. The above-mentioned rotational positions are shown in fig. 7 to 9, respectively.

Fig. 7 shows the first rotational position. In this rotational position, water flowing into the switching valve body 100 from the valve body water inlet port flows into the movable valve sheet 40 through the movable sheet water inlet portion 401 of the movable valve sheet 40, is guided by the passive sheet water inlet portion 401 to flow downward into the groove 501 of the fixed valve sheet 50, flows obliquely upward after being accumulated in the groove 501, and flows out of the movable valve sheet 40 through the movable sheet water outlet port 402.

The movable valve plate water outlet 402 is communicated with the cavity 201 in the rotating shaft 20. The water leaving the movable valve plate 40 thus flows through the cavity 201 to the upper valve element water outlet 103 of the switching valve element 100 at the upper end of the rotating shaft 20 and leaves the switching valve element 100.

In the first rotational position, the flow path of the water in the switching spool 100 is: enters the switching valve core 100 from the water inlet of the valve core, enters the movable valve sheet water inlet part 401 of the movable valve sheet 40, enters the groove 501 of the fixed valve sheet 50, enters the movable valve sheet water outlet 402 of the movable valve sheet 40, enters the cavity 201 of the rotating shaft 20, enters the switching valve core water outlet 103 of the switching valve core 100 and leaves the switching valve core 100.

The first rotational position enables an upward water outlet mode. The cartridge upper outlet 103 may be connected to an upper outlet portion O3 of a faucet such as that shown in fig. 1, and further connected to a top shower of a shower assembly.

By operating the protrusion 301 of the switching handle 30, the switching spool 100 can be rotated from the first rotational position shown in fig. 7 to the second rotational position shown in fig. 8. In this rotational position, water flowing into the switching valve cartridge 100 from the cartridge water inlet port flows into the movable valve sheet 40 through the movable valve sheet water inlet portion 401 of the movable valve sheet 40, and the water is guided to flow downward by the movable valve sheet water inlet portion 401. In the second rotation position, the movable valve plate water inlet portion 401 is communicated with the first fixed valve plate water outlet 502 of the fixed valve plate 50. Thus, the downwardly directed water flow passes through the first retainer outlet 502 and the first under-seat outlet 602, and exits the switching cartridge 100.

In the second rotational position, the flow path of the water in the switch spool 100 is: enters the switching valve core 100 from the water inlet of the valve core, enters the movable valve sheet water inlet part 401 of the movable valve sheet 40, enters the first fixed valve sheet water outlet 502 of the fixed valve sheet 50, enters the first valve seat lower water outlet 602 of the valve seat 60 and leaves the switching valve core 100.

The second rotational position enables a lower water outlet mode. The first, lower valve seat outlet 602 of the valve seat 60 may be connected to e.g. the tap water outlet O2 of the tap shown in fig. 1, i.e. in the second rotational position, water may be discharged from the tap shown in fig. 1 directly via O2.

Continuing to operate the protrusion 301 of the switching knob 30, the switching spool 100 can be rotated from the second rotational position shown in fig. 8 to the third rotational position shown in fig. 9.

In this rotational position, water flowing into the switching spool 100 from the spool water inlet port flows into the movable valve sheet 40 through the movable valve sheet water inlet portion 401 of the movable valve sheet 40, and is guided to flow downward by the movable valve sheet water inlet portion 401. In the third rotation position, the movable valve plate water inlet portion 401 is communicated with the second fixed valve plate water outlet 503 of the fixed valve plate 50. Therefore, the downwardly directed water flows out of the switching valve cartridge 100 through the second fixed valve plate outlet 503 and the second seat lower outlet 603.

In the third rotational position, the flow path of the water in the switch spool 100 is: enters the switching valve core 100 from the water inlet of the valve core, enters the movable valve sheet water inlet part 401 of the movable valve sheet 40, enters the second fixed valve sheet water outlet 503 of the fixed valve sheet 50, enters the second valve seat lower water outlet 603 of the valve seat 60 and leaves the switching valve core 100.

The third rotational position enables another lower water discharge mode. The second valve seat lower outlet 603 of the valve seat 60 may be connected to a lower outlet portion O3 of a faucet, such as that shown in fig. 1, and further connected to a hand held shower, such as by a hose.

Thus, the switching valve cartridge 100 shown can support a one-up, two-down water outlet mode.

It should be noted that, in the above embodiment, the case of the movable valve plate water outlet and the fixed valve plate water outlet provided on the movable valve plate and the fixed valve plate is described, but the utility model is not limited thereto. The quantity of the water outlets of the movable valve plate and the fixed valve plate can be adjusted according to needs, and the closing position can be increased.

It should be noted that, in the above embodiment, the shapes of the water inlet portion of the movable valve plate provided in the movable valve plate and the groove provided in the fixed valve plate are described, but the present invention is not limited thereto. The shapes of the water inlet part and the groove of the movable valve plate on the movable valve plate and the fixed valve plate can be changed as required.

In the illustrated embodiment, the first rotation position and the second rotation position and the third rotation position are all separated by 90 °, but the present invention is not limited thereto, and the angle between the rotation positions may be set according to specific needs, and the arrangement and the angle separation of the openings and the grooves on the movable valve plate and the fixed valve plate may be adjusted correspondingly.

According to the switching valve core, the water outlet is regulated and controlled in the linear direction through the design of the multi-cavity special-shaped fixed valve plate and the movable valve plate and the matching between the multi-cavity special-shaped fixed valve plate and the movable valve plate, the water channel does not need to be replaced, and redundant auxiliary accessories are also not needed. This makes the switching valve cartridge of the present invention and faucet and shower post assembly including it simple in construction, easy to use and save installation space.

In the present invention, the embodiments may be freely combined, or may be appropriately modified or omitted within the scope of the present invention.
