Description

Technical Field

[0001] The utility model relates to an immediately-turn-off component and a shower head. Background Art

[0002] In existing water outlet devices, such as shower heads, when the water flow control switch is closed, since there is still residual water in the shower head, this part of the residual water will continue to flow out after the control switch is closed, thus wetting the human body or the floor and resulting in a poor user experience. To avoid the problem that water still flows out after the water flow control switch in the prior art is closed, some solutions in the prior art set duckbill valves on each water outlet. The duckbill valves open the water outlets under the action of water flow pressure and automatically close the water outlets when the water flow pressure disappears or is insufficient, thus solving the above problem.

[0003] However, the prior art usually integrally forms the duckbill valves corresponding to the water outlets of the water outlet device. Although this is convenient for assembly, the immediately-turn-off component formed by integrally molding multiple duckbill valves has poor versatility. For different layouts of the shower head water outlets, immediately-turn-off components with different layouts are required, and the manufacturing cost is relatively high. Summary of the Utility Model

[0004] To solve the above technical problems, the purpose of the utility model is to provide an immediately-turn-off component and a shower head with the immediately-turn-off component. The component has a simple structure and good versatility, and the immediately-turn-off component can be flexibly selected and installed according to the layout of the water outlets of different water outlet devices.

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model 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 only used to explain the present utility model and are not used to limit the present utility model.

[0040] In the following discussion, details are given to provide a more thorough understanding of the present utility model. However, those skilled in the art can understand that the present utility model can be implemented without one or more of these details. In specific examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described in detail. It should be noted that the terms "upper", "lower", "front", "rear", "left", "right" and similar expressions used herein are only for the purpose of illustration and are not limiting.

[0041] The ordinal numbers such as "first" and "second" cited in the present utility model are only identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component".

[0042] Please refer to Figures 1 to 11, a kind of on - off - immediately component 1 provided by the present utility model is used to be installed at the water outlet of a water outlet device. Hereinafter, the water outlet device takes a shower head 2 as an example for illustration. The shower head 2 has a plurality of water outlets 210, and the on - off - immediately component 1 is installed at the water outlet 210.

[0043] The on - off - immediately component 1 includes a body 10 and a switch valve 20. The body 10 has an inner cavity 11, a water inlet 12 and a plurality of water outlet holes 13 that are all communicated with the inner cavity 11; the switch valve 20 is arranged in the body 10. The switch valve 20 has a switch water inlet 21 and a switch water outlet 22. The switch water inlet 21 is communicated with the water inlet 12, and the switch water outlet 22 is communicated with the water outlet holes 13. That is to say, the water flow at the water inlet 12 flows out of the water outlet holes 13 after passing through the switch water inlet 21 and the switch water outlet 22 in sequence. The switch valve 20 can be opened under the action of the water pressure at the water inlet 12 to connect the water inlet 12 and the water outlet holes 13 to realize the water passing of the on - off - immediately component 1 (see Figure 11 ); and can be automatically closed when the water pressure at the water inlet 12 disappears or is insufficient to cut off the connection between the water inlet 12 and the water outlet holes 13 to realize the water stopping of the on - off - immediately component 1 (see Figure 10 ).

[0044] Through the above - mentioned scheme of setting the on - off - immediately component 1 as an independent module, the on - off - immediately component 1 is provided with a switch valve 20 by itself. Through the switch valve 20, it can be opened under the action of the water pressure at the water inlet 12 of the body 10 to connect the water inlet 12 and the water outlet holes 13 so as to realize the water outlet of the water outlet device (shower head 2), and can be automatically closed when the water pressure at the water inlet 12 disappears or is insufficient to cut off the connection between the water inlet 12 and the water outlet holes 13 so as to realize the water stopping of the water outlet device. Since the on - off - immediately component 1 is an independent module, when manufacturing the water outlet device (shower head 2), different numbers of on - off - immediately components 1 can be selected and matched as needed, and the on - off - immediately component 1 can be flexibly selected and installed according to the water outlet layout of different water outlet devices. Therefore, the on - off - immediately component has good versatility and a simple structure. In addition, the on - off - immediately component 1 designed as an independent module can be independently assembled, tested, stored and sold, etc., and is very convenient to use.

[0045] In this embodiment, the opening or closing of the switch valve 20 is controlled by the switch water outlet 22. That is to say, when the switch water outlet 22 is opened, that is, the switch valve 20 is in the open water - outlet state, and when the switch water outlet 22 is closed, that is, the switch valve 20 is in the closed water - cut - off state. In other embodiments, the opening or closing of the switch valve 20 can also be controlled by the switch water inlet 21. That is to say, when the switch water inlet 21 is opened, that is, the switch valve 20 is in the open water - outlet state, and when the switch water inlet 21 is closed, that is, the switch valve 20 is in the closed water - cut - off state.

[0046] Specifically, in this embodiment, the body 10 is cylindrical, and the water inlet 12 and the water outlet hole 13 are respectively located at both ends of the body 10 in the axial direction. That is, the water inlet 12 and the water outlet hole 13 are oppositely arranged. Such a setting has a simple and compact structure. For the convenience of forming and assembling the body 10, the body 10 includes an inner cylinder 14 with openings at both ends and an outer cylinder 15 with an opening at the top. The inner cylinder 14 is sleeved inside the outer cylinder 15 and encloses an inner cavity 11 with the outer cylinder 15. The top opening of the inner cylinder 14 forms the water inlet 12, and the bottom end of the outer cylinder 15 is provided with the water outlet hole 13. The inner cylinder 14 and the outer cylinder 15 can be assembled into one body by means of snap connection, screw connection, welding, interference fit, etc., so as to facilitate storage and assembly.

[0047] In this embodiment, a plurality of spaced-apart guide columns 16 are provided on the periphery of the body 10 at the water inlet 12. Flow-through gaps are formed between the guide columns 16, and the internal water flow of the water outlet device (shower head 2) (specifically, the water flow in the flow-through channel 310 described below in this embodiment) enters the water inlet 12 of the body 10 through the flow-through gaps.

[0048] In this embodiment, the switch valve 20 is a duckbill valve. The duckbill valve includes a connected cylindrical section 23 and a deformed section 24. The cylindrical section 23 is provided with a switch water inlet 21 and is located at the water inlet 12. The deformed section 24 is provided with a switch water outlet 22 and extends into the inner cavity 11. The deformed section 24 opens or closes the switch water outlet 22 through its own elastic deformation. The switch valve 20 being a duckbill valve has a simple structure, is convenient for assembly, and has reliable functions.

[0049] In this embodiment, a plurality of limit columns 231 are provided on the end face of the cylindrical section 23 along the circumferential direction. The limit columns 231 are used to abut against the external fixing structure of the on-off component 1 (specifically, the housing 100 of the shower head 1 described below in this embodiment) to prevent the duckbill valve from detaching from the body 10.

[0050] It can be understood that the switch valve 20 of the present utility model is not limited to the duckbill valve. In other embodiments, the switch valve 20 can also be an elastic valve core (not shown) that cooperates with the opening and closing of the switch water inlet 21 or the switch water outlet 22. The elastic valve core can include a spring and a valve core. The valve core cooperates with the switch water inlet 21 or the switch water outlet 22, and the spring provides an elastic restoring force to the valve core. The water pressure at the water inlet 12 overcomes the elastic force of the spring to open the valve core to connect the water inlet 12 and the water outlet hole 13 to realize water flow through the on-off component 1; when the water pressure at the water inlet 12 disappears or is insufficient, the elastic restoring force of the spring makes the valve core automatically close to cut off the connection between the water inlet 12 and the water outlet hole 13 to realize water stop of the on-off component 1.

[0051] See Figures 7 to 11, the present utility model further provides a shower head 2, which includes a housing 100 and a water outlet panel 200 having a plurality of water outlets 210. The housing 100 and the water outlet panel 200 are fixedly connected and enclose the inner cavity of the shower head. The shower head 2 further includes the instant-off component 1 of any one of the above, and the instant-off component 1 is installed at the water outlet 210 of the shower head 2.

[0052] In order to replace or repair the instant-off component 1, in this embodiment, the instant-off component 1 is detachably installed at the water outlet 210 of the water outlet device. Specifically, the instant-off component 1 is detachably installed at the water outlet 210 in a manner of interference fit.

[0053] More specifically, in this embodiment, the shower head further includes a water distribution plate 300. The water distribution plate 300 is disposed in the inner cavity of the shower head. The water distribution plate 300 is provided with a water flow channel 310 and a plurality of water flow holes 320. Each water flow hole 320 is communicated with the water flow channel 310, and each water flow hole 320 corresponds to the position of each water outlet 210. The instant-off component 1 is installed between each water flow hole 320 and the water outlet 210; an annular sealing ring groove 17 is provided on the outer peripheral wall of the body 10, and a sealing ring 171 is provided on the sealing ring groove 17. The instant-off component 1 is hermetically inserted into the water outlet 210 through the sealing ring 171. With such a design, the internal structure of the shower head 2 is simple and compact, and it is very convenient to assemble the instant-off component 1 on the shower head 2.
