Description

Technical Field

[0001] The utility model relates to a water outlet device that can be turned off immediately when the water flow is stopped. Background Art

[0002] In the existing water outlet devices, such as shower heads, when the water flow control switch is turned off, 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 turned off, thus wetting the human body or the floor and resulting in a poor user experience. In order to avoid the problem that water still flows out after the water flow control switch is turned off in the prior art, some solutions in the prior art set check valves on each water outlet nozzle. The check valve opens the water outlet nozzle under the action of water flow pressure and automatically closes the water outlet nozzle when the water flow pressure disappears or is insufficient, thus solving the above problem.

[0003] However, the prior art usually adopts a structure in which check valves are set on each water outlet nozzle that discharges the same water flow. The number of check valves is large, and the assembly is not easy, and the structure is relatively complex. Summary of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a water outlet device that can be turned off immediately when the water flow is stopped, which has a simple structure, can realize the function of turning off immediately when the water flow is stopped, and is convenient for assembly.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A water outlet device that can be turned off immediately when the water flow is stopped, comprising a body and a water outlet panel connected to the body and enclosing an inner cavity. The body is provided with a water inlet, the water outlet panel is provided with a plurality of water outlet nozzles, the inner cavity is divided into a water passing cavity and a water outlet cavity by a water distribution plate. The water inlet is communicated with the water passing cavity, the water outlet nozzles are communicated with the water outlet cavity. One side of the water distribution plate and the body enclose the water passing cavity, the other side of the water distribution plate and the water outlet panel enclose a plurality of the water outlet cavities, and the water distribution plate is provided with water passing openings communicating the water passing cavity and the water outlet cavity; check valves are provided on each of the water passing openings, and the check valve can open the water passing opening under the action of the water flow pressure in the water passing cavity and automatically close the water passing opening when the water flow pressure in the water passing cavity disappears or is insufficient.

[0007] Preferably, a plurality of the water outlet nozzles are provided on one water outlet cavity, and one water outlet cavity is communicated with the water passing cavity through at least one water passing opening.

[0008] Preferably, the body includes a housing and a pressing plate fixed in the housing. The water outlet panel is connected to the housing to enclose the inner cavity. The pressing plate is connected to the water distribution plate to enclose the water passing cavity, and the check valve is clamped between the pressing plate and the water distribution plate.

[0009] Preferably, partition ribs are provided on one side of the water dividing plate facing the water outlet panel, and / or partition ribs are provided on one side of the water outlet panel facing the water dividing plate, so that each of the water outlet cavities is hermetically isolated from each other through the partition ribs.

[0010] Preferably, the water outlet panel includes an inner plate made of a soft material and an outer plate made of a hard material. The inner plate is attached to the inner side of the outer plate, and a plurality of water outlet nozzles are integrally formed on the inner plate. Avoidance openings for each of the water outlet nozzles to pass through are provided on the outer plate.

[0011] Preferably, partition ribs are provided on one side of the water dividing plate facing the water outlet panel, and / or partition ribs are provided on one side of the inner plate facing the water dividing plate, so that each of the water outlet cavities is hermetically isolated from each other through the partition ribs.

[0013] Preferably, the water flower shapes flowing out of each of the water outlet nozzles are the same.

[0014] Preferably, the water outlet device is a shower head.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the utility model, the inner cavity of the water outlet device is divided into a water passing cavity and a water outlet cavity by a water dividing plate. The water inlet is communicated with the water passing cavity, and the water outlet nozzle is communicated with the water outlet cavity. A water passing cavity is formed between one side of the water dividing plate and the body, and a plurality of water outlet cavities are formed between the other side of the water dividing plate and the water outlet panel. Water passing openings communicating the water passing cavity and the water outlet cavity are provided on the water dividing plate; one-way valves are provided on each of the water passing openings. The one-way valve can open the water passing opening under the action of the water flow pressure in the water passing cavity, and automatically close the water passing opening when the water flow pressure in the water passing cavity disappears or is insufficient. In this way, a plurality of water outlet cavities are all communicated with the same water passing cavity, and the water passing cavity and each water outlet cavity are communicated or cut off through the one-way valve. When the water outlet device stops supplying water, the amount of water in the water passing cavity is relatively large, and the amount of water in each water outlet cavity is relatively small. The water flow in the water passing cavity will not flow into the water outlet cavity under the action of the one-way valve, and since the amount of water in each water outlet cavity is relatively small, it can be basically discharged from the water outlet nozzle when the water supply is stopped, so as to achieve the effect of stopping immediately when closed. The structure is simple and the function is reliable. Moreover, the one-way valve is independently arranged at the position of the water dividing plate relative to the water outlet nozzle, and the assembly is simpler and easier. In addition, since one one-way valve can be designed to correspondingly control the on-off of a plurality of water outlet nozzles, there is no need to provide a one-way valve for control on each water outlet nozzle. The number of one-way valves is small, which can reduce costs, improve the assembly efficiency, and simplify the structure. The one-way valve in the present application can control a plurality of water outlet nozzles in a partitioned manner, and the concept is ingenious. Description of the Drawings

[0034] Please refer to Figures 1 to 7 , a water outlet device that shuts off immediately upon closing provided by the present utility model in a preferred embodiment includes a body 10 and a water outlet panel 20 connected to the body 10 and enclosing an inner cavity 13. The body 10 is provided with a water inlet 14, and the water outlet panel 20 is provided with a plurality of water outlet nozzles 21. The inner cavity 13 is divided into a water passing cavity 131 and a water outlet cavity 132 by a water distribution plate 30. The water inlet 14 is communicated with the water passing cavity 131, and the water outlet nozzles 21 are communicated with the water outlet cavity 132. A water passing cavity 131 is formed between one side of the water distribution plate 30 and the body 10, and a plurality of water outlet cavities 132 are formed between the other side of the water distribution plate 30 and the water outlet panel 20. The water distribution plate 30 is provided with water passing openings 31 communicating the water passing cavity 131 and the water outlet cavity 132. That is, the water inlet 14 is communicated with the water outlet nozzles 21 through the water passing cavity 131, the water passing openings 31, and the water outlet cavity 132 in sequence; one-way valves 40 are provided on each of the water passing openings 31. The one-way valves 40 can open the water passing openings 31 under the action of the water flow pressure in the water passing cavity 131 (i.e., the water inlet pressure of the water inlet 14), and automatically close the water passing openings 31 when the water flow pressure in the water passing cavity 131 disappears or is insufficient (i.e., the water inlet 14 stops supplying water).

[0035] In this embodiment, the water outlet device is a shower head. Of course, in other embodiments, the water outlet device can also be a faucet or the like.

[0036] In this embodiment, a plurality of water outlet nozzles 21 are provided on one water outlet cavity 132, and one water outlet cavity 132 is communicated with the water passing cavity 131 through one water passing opening 31. That is, the communication or cut-off between one water outlet cavity 132 and the water passing cavity 131 is controlled by one one-way valve 40. Of course, in other embodiments, one water outlet cavity 132 can also be designed to be communicated with the water passing cavity 131 through more than two water passing openings 31. That is, the communication or cut-off between one water outlet cavity 132 and the water passing cavity 131 can be designed to be controlled by more than two one-way valves 40.

[0037] In this embodiment, the main body 10 includes a housing 11 and a pressing plate 12 fixedly arranged inside the housing 11. The water outlet panel 20 is connected to the housing 11 to enclose an inner cavity 13. The pressing plate 12 is connected to the water distribution tray 30 to enclose a water passing cavity 131. The one-way valve 40 is clamped between the pressing plate 12 and the water distribution tray 30. In this way, during assembly, when the pressing plate 12 is fixedly connected to the water distribution tray 30, the one-way valve 40 can be clamped and fixed at the same time, and the assembly is simple and convenient.

[0038] In this embodiment, referring to Figure 6 , on one side of the water distribution tray 30 facing the water outlet panel 20, there are partition ribs 32, and on one side of the water outlet panel 20 facing the water distribution tray 30, there are also partition ribs 22. The partition ribs 22 on the water outlet panel 20 cooperate with the partition ribs 32 on the water distribution tray 30 correspondingly. Through the partition ribs 22 and 32 at the two places, each water outlet cavity 132 is hermetically isolated from each other. It can be understood that in other embodiments, the partition ribs can also be provided only on the water outlet panel 20 or only on the water distribution tray 30, as long as each water outlet cavity 132 can be hermetically isolated from each other.

[0039] Specifically, the water outlet panel 20 includes an inner plate 23 made of a soft material and an outer plate 24 made of a hard material. The inner plate 23 is attached to the inner side of the outer plate 24. A plurality of water outlet nozzles 21 and partition ribs 22 are integrally formed on the inner plate 24. That is to say, the water outlet nozzles 21 and the partition ribs 22 are also made of a soft material. The outer plate 24 is provided with avoidance openings 241 for each water outlet nozzle 21 to pass through. The inner plate 23 can be made of common soft materials such as silica gel, and the outer plate 24 can be made of common plastic materials such as ABS.

[0040] In this embodiment, referring to Figure 4 and Figure 5 , the one-way valve 40 is a duckbill valve, which is made of an elastic material such as silica gel. Figure 4 is a schematic diagram of the duckbill valve in the closed state, Figure 5 is a schematic diagram of the duckbill valve in the open state. The duckbill valve is opened or closed and reset through the elastic deformation of the silica gel itself, with a simple structure and reliable function.

[0041] In this embodiment, the water flower shapes flowing out of each of the water outlet nozzles 21 are the same.

[0042] In the present utility model, multiple water outlet cavities are all connected to the same water passing cavity, and the water passing cavity and each water outlet cavity are connected or cut off through one-way valves. When the water outlet device stops water supply, there is more water in the water passing cavity and less water in each water outlet cavity. Under the action of the one-way valves, the water flow in the water passing cavity will not flow into the water outlet cavity, and since there is less water in each water outlet cavity, it can be basically discharged from the water outlet nozzle when the water supply stops, thus achieving the effect of stopping immediately when closed. The structure is simple and the function is reliable. Moreover, the one-way valves are arranged at the position of the water distribution plate independently of the water outlet nozzles, and the assembly is simpler and easier. In addition, since one one-way valve can be designed to correspondingly control the immediate stop of multiple water outlet nozzles, there is no need to set a one-way valve for each water outlet nozzle for control. The number of one-way valves is small, which can reduce costs, speed up the assembly efficiency, and simplify the structure. The one-way valves in this application can control multiple water outlet nozzles in different regions, with a clever concept.
