Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a switching structure of a shower head. Background Art

[0002] Switching the water outlet is a common feature of showerheads. Users can adjust the water flow by controlling a switch, such as shower water, granular water, atomized water, massage water, and more. To meet diverse consumer needs, manufacturers have developed various switch configurations. The most common is the one that switches by rotating the water outlet panel. This type of configuration requires the panel to be pivoted and installed at the outlet end of the showerhead, often using a central screw. Although this type of switching structure technical solution is very mature and widely adopted, it still has the following shortcomings: 1. The rotating water outlet panel has high sealing requirements, which results in high manufacturing precision requirements for the shower head and high manufacturing costs; 2. The water outlet panel and the shower head are not completely integrated structures. During use, it is inevitable that the shower head will fall or bump, which can easily cause the sealing of the water outlet panel to fail and cause dripping problems; 3. The rotating installation of the entire water outlet panel is prone to loosening of the middle screws after a long time. Therefore, the utility model provides a shower head switching structure that combines a fixed water outlet panel with a toggle switch at the water outlet panel to solve the above technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the present utility model provides a more durable shower water outlet switching structure.

[0004] A switching structure for a shower head comprises a shower head, a first switching valve and a switching drive frame.

[0005] The shower head is provided with a water flow channel, a first mounting cavity, and a water outlet channel. The first switching valve is rotatably mounted within the first mounting cavity. There are at least two water outlet channels, and the water flow channel is connected to any of the water outlet channels through the rotational switching action of the first switching valve. The water outlet panel of the shower head is provided with an arc-shaped opening, the arc-shaped opening being centered on the rotation axis of the first switching valve.

[0006] The switching drive frame is arranged in the shower head, one end of which is fixedly installed relative to the valve stem of the first switching valve, and the other end is a driving end and is provided with a dial knob extending from the arc-shaped opening.

[0007] The switching structure provided by the utility model has a switch in the form of a dial knob with an arc-shaped moving trajectory, and is arranged at the water outlet panel of the shower head. On the one hand, it inherits the operational convenience and intuitiveness of the traditional water outlet panel rotation switching structure. On the other hand, the switching drive frame replaces the rotatably mounted water outlet panel, so that the water outlet panel and the shower head can be relatively fixedly installed, avoiding the problems of high sealing requirements and vulnerability to damage.

[0008] Preferably, a switch cap is provided on the outside of the knob, and the diameter of the switch cap is larger than the width of the arc-shaped opening, which facilitates operation on the one hand and can further limit the switching drive frame on the other hand, thereby improving its installation stability.

[0009] Preferably, the switch drive frame is fan-shaped as a whole to prevent the middle portion of the switch drive frame from twisting when the knob is pushed.

[0010] Preferably, to enhance the showerhead's water flow capabilities, the showerhead head further comprises a water inlet channel, a second mounting cavity, a spray gun water channel, and a nozzle. Both the water flow channel and the spray gun water channel communicate with the water inlet channel via the second mounting cavity. The switching structure further comprises a second switching valve mounted within the second mounting cavity. The water inlet channel communicates with either the water flow channel or the spray gun water channel upon switching of the second switching valve.

[0011] Preferably, a clearance opening is provided in the middle of the switching drive frame, and the switching drive frame surrounds the periphery of the second installation cavity through the clearance opening to form a compact layout and avoid space waste.

[0012] Preferably, the water inlet channel extends from the periphery of the second installation cavity and presses the driving end of the switching drive frame.

[0013] Preferably, the second switching valve adopts a pressing mechanism and is provided with a pressing button extending to the outside of the shower head. When using the spray gun water, a pressing method is adopted, which is convenient to use.

[0014] Preferably, to avoid trouble when using water again, the second switching valve adopts an automatic reset structure when the water is turned off. When the water is turned off, it automatically switches from the spray gun water state to the shower water state. It also includes a telescopic valve stem and a reset spring. The spray gun water channel, the water inlet channel, and the water flow channel are sequentially provided with connecting holes axially within the second mounting cavity.

The reset spring is compressed and arranged between the end of the second mounting cavity and the end of the telescopic valve stem. The push button is mounted at the end of the telescopic valve stem extending out of the second mounting cavity. When the push button is used to press the telescopic valve stem, the plug blocks the water inlet channel, and the spray gun water channel and the water flow channel are connected. When the push button is released, the reset spring pushes the telescopic valve stem and the plug to reset. The plug blocks the spray gun water channel, and the water inlet channel and the water flow channel are connected.

[0015] Preferably, when water is flowing and the spray gun water channel and the water passage are connected, the water force acting on the telescopic valve stem is greater than or equal to the reset force of the reset spring, so that when the water is flowing, the user does not need to keep pressing the push button when using the spray gun water.

[0016] Preferably, there are three water outlet channels, and three types of water outlet nozzles are provided correspondingly. When the knob slides to the two ends and the middle position of the arc-shaped opening, water flows out from the three types of water outlet nozzles respectively.

[0017] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0018] The switch provided by the utility model is a toggle with an arc-shaped moving trajectory and is arranged on the water outlet panel of the shower head. On the one hand, it inherits the operational convenience and intuitiveness of the traditional water outlet panel rotation switching structure. On the other hand, the switching drive frame replaces the rotatably mounted water outlet panel, so that the water outlet panel and the shower head can be relatively fixedly installed, avoiding the problems of high sealing requirements and easy damage due to collision, making the shower more durable and having a longer service life.

[0019] The switching drive frame is fan-shaped as a whole to prevent the middle part of the switching drive frame from twisting when the knob is pushed;

[0020] The shower head is further provided with a water inlet channel, a second mounting cavity, a spray gun water channel and a nozzle to increase the water discharge function of the shower head;

DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is 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 invention and are not intended to limit the present invention.

[0035] See also Figures 1 to 7 A switching structure of a shower head includes a shower head 1, a first switching valve 2 and a switching drive frame 3.

[0036] The shower head 1 is provided with a water passage 11, a first mounting cavity 12, and a water outlet passage 13. The first switching valve 2 is rotatably mounted within the first mounting cavity 12. There are at least two water outlet passages 13. The water passage 11 is connected to any of the water outlet passages 13 by the rotational switching action of the first switching valve 2. The water outlet panel of the shower head 1 is provided with an arc-shaped opening 14, centered on the rotation axis of the first switching valve 2.

[0037] The switch drive frame 3 is mounted within the shower head 1. One end is fixedly mounted relative to the valve stem of the first switch valve 2. The other end serves as a drive end and is equipped with a toggle knob 31 extending from the arc-shaped opening 14. In this embodiment, the water outlet channels 13 have three corresponding water outlets. Sliding the toggle knob 31 to the ends and center of the arc-shaped opening 14 causes water to flow from the three outlets, respectively.

[0038] In one embodiment, a switch cap 32 is sleeved around the outer portion of the toggle knob 31. The diameter of the switch cap 32 is larger than the width of the arc-shaped opening 14. This facilitates operation and further limits the position of the switch drive frame 3, improving its installation stability. Furthermore, in other embodiments, the switch drive frame 3 is fan-shaped to prevent distortion in the middle of the switch drive frame 3 when the toggle knob 31 is pushed.

[0039] To enhance the showerhead's water-discharging capabilities, in one embodiment, the showerhead 1 further comprises a water inlet channel 15, a second mounting cavity 16, a spray gun water channel 17, and a nozzle 18. Both the water flow channel 11 and the spray gun water channel 17 communicate with the water inlet channel 15 via the second mounting cavity 16. The switching mechanism further comprises a second switching valve 4 mounted within the second mounting cavity 16. The water inlet channel 15 communicates with either the water flow channel 11 or the spray gun water channel 17 through the switching action of the second switching valve 4.

[0040] In one embodiment, a clearance opening 33 is provided in the middle of the switching drive frame 3. The switching drive frame 3 surrounds the second mounting cavity 16 through the clearance opening 33, forming a compact layout and avoiding space waste. In another embodiment, the water inlet channel 15 extends from the periphery of the second mounting cavity 16 and presses against the driving end of the switching drive frame 3, improving the installation stability of the switching drive frame 3.

[0041] In this embodiment, the second switching valve 4 adopts a pressing mechanism and is provided with a pressing button 41 extending to the outside of the shower head 1. When using the spray gun water, a pressing method is adopted, which is convenient to use.

[0042] Furthermore, in other embodiments, to avoid trouble when using water again, the second switching valve 4 adopts an automatic reset structure when the water is cut off. When the water is turned off, it will automatically switch from the spray gun water state to the shower water state, and also includes a telescopic valve rod 42 and a reset spring 43. The spray gun water channel 17, the water inlet channel 15 and the water flow channel 11 are provided with connecting holes in sequence in the axial direction of the second installation cavity 16. The telescopic valve stem 42 is telescopically installed in the second installation cavity 16 and is provided with a plug 44. The return spring 43 is compressed and arranged between the end of the second installation cavity 16 and the end of the telescopic valve stem 42. The press key 41 is installed at the end of the telescopic valve stem 42 extending out of the second installation cavity 16. The telescopic valve stem 42 is pressed by the press key 41, the plug 44 blocks the water inlet channel 15, and the spray gun water channel 17 and the water flow channel 11 are connected. When the press key 41 is released, the return spring 43 pushes the telescopic valve stem 42 and the plug 44 to reset. The plug 44 blocks the spray gun water channel 17, and the water inlet channel 15 and the water flow channel 11 are connected. In addition, when water is flowing and the spray gun water channel 17 is connected to the water channel 11, the water force on the telescopic valve stem 42 is greater than or equal to the reset force of the reset spring 43. Therefore, when the water is flowing, the user does not need to keep pressing the push button 41 when using the spray gun water.

[0043] The switching structure provided by the present invention has a switch in the form of a dial knob 31 with an arc-shaped moving trajectory, and is arranged at the water outlet panel of the shower head 1. On the one hand, it inherits the operational convenience and intuitiveness of the traditional water outlet panel rotation switching structure. On the other hand, the switching drive frame 3 replaces the rotatably mounted water outlet panel, so that the water outlet panel and the shower head 1 can be relatively fixedly installed, avoiding the problems of high sealing requirements and vulnerability to damage.
