[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Please refer to the attached document. Figures 1-10 This application provides a push-button switch assembly 100, which is part of a shower head device. The push-button switch assembly 100 is used to control the water channel 200 of the shower head device to be in an open or closed state.

[0054] Please refer to the attached document. Figures 1-10 In this embodiment, the push-button switch assembly 100 includes a push-button switch 10 and a sealing sleeve 20. The push-button switch 10 is pressably connected to the water channel 200 of the shower head device, so that the water channel 200 is in an open or closed state. The sealing sleeve 20 is sleeved on the push-button switch 10 and is located inside the water channel 200. The sealing sleeve 20 has an annular cavity 20a, which is arranged along the periphery of the sealing sleeve 20. When the water channel 200 is in a closed state, the annular cavity 20a is connected to the first water passage cavity 200a inside the water channel 200 along its own annular direction. The first water passage cavity 200a is used to connect to the water inlet. The connection between the annular cavity 20a and the first water passage cavity 200a inside the water channel 200 will not cause any blockage or imbalance, so that the sealing sleeve 20 is pressurized in the annular direction. This avoids the push-button switch 10 being pressurized at only one end, which would result in an unbalanced pressure and improves the pressing effect of the push-button switch 10 relative to the water channel 200 in the push-button switch assembly 100.

[0055] Please refer to the attached document. Figures 1-10In this embodiment of the application, the push-button switch 10 is pressably connected to the water channel 200 of the shower device so as to adjust the position of the push-button switch 10 relative to the water channel 200 of the shower device, so that the water channel 200 is in an open or closed state, so as to control the flow or disconnection of the water channel 200 of the shower pipe through the push-button switch 10, thereby saving water.

[0056] A sealing sleeve 20 is fitted onto the push-button switch 10 and located within the water channel 200, so that the sealing sleeve 20 can move as the push-button switch 10 is pressed, thereby facilitating the adjustment of the position of the sealing sleeve 20 relative to the water channel 200 of the shower pipe. The sealing sleeve 20 has an annular cavity 20a, which is arranged along the periphery of the sealing sleeve 20. When the water channel 200 is closed, the annular cavity 20a connects to the first water passage cavity 200a within the water channel 200 along its own annular direction. The first water passage cavity 200a is used to connect to the water inlet component. The connection between the annular cavity 20a and the first water passage cavity 200a within the water channel 200 ensures that the sealing sleeve 20 is pressurized evenly in the annular direction, preventing the push-button switch 10 from being pressurized at only one end and causing pressure imbalance. This reduces the pressing force of the push-button switch 10 relative to the water channel 200 in the push-button switch assembly 100, resulting in better tactile feedback.

[0057] In this embodiment, the sealing sleeve 20 includes a sealing sleeve body 21, which is sleeved on the push-button switch 10 so that the sealing sleeve 20 can be connected to the push-button switch 10 through the sealing sleeve body 21. An annular cavity 20a is formed on the periphery of the sealing sleeve body 21. The first end and the last end of the annular cavity 20a are both connected to the water passage end of the first water passage cavity 200a, so that the water output from the water inlet can circulate along the water passage end of the first water passage cavity 200a, the first end of the annular cavity 20a, and the last end of the annular cavity 20a. This facilitates the even distribution of water pressure in the annular direction of the annular cavity 20a, making the sealing sleeve 20 pressurized in the annular direction. This avoids the push-button switch 10 being pressurized on only one end, resulting in pressure imbalance, and improves the pressing effect of the push-button switch 10 relative to the water channel 200 in the push-button switch assembly 100.

[0058] In this embodiment, the sealing sleeve body 21 is provided with a stepped groove 21a, which is arranged along the length of the sealing sleeve body 21 to facilitate the vertical distribution of water pressure. This makes it easier to disperse water pressure to both the upper and lower sides.

[0059] In this embodiment of the application, the sealing sleeve 20 further includes at least one edge portion 22, which is arranged around the periphery of the sealing sleeve body 21 and can sealably contact the inner wall of the water channel 200, so that the sealing sleeve 20 can block the water flow in the first water passage 200a in the water channel 200 through the edge portion 22, thereby facilitating the sealing of the other end of the water channel 200 in the first water passage 200a, so as to realize that the button switch 10 makes the water channel 200 in the closed state.

[0060] In this embodiment, there are two edge portions 22, which are distributed at both ends of the sealing sleeve body 21. The edge portions 22 are arranged at an inclination relative to the sealing sleeve body 21. By arranging the two edge portions 22, the upper and lower ends of the first water passage cavity 200a in the water channel 200 are blocked, thereby improving the sealing effect of the sealing sleeve 20 and ensuring the closing effect of the button switch 10 relative to the water channel 200.

[0061] In this embodiment, the sealing sleeve 20 is integrally formed on the push button switch 10, which ensures the connection stability between the sealing sleeve 20 and the push button switch 10, improves the connection strength between the sealing sleeve 20 and the push button switch 10, and prevents the sealing sleeve 20 from detaching from the push button switch 10.

[0062] Alternatively, the sealing sleeve 20 can be separately connected to the push button switch 10, so that the sealing sleeve 20 can be connected to or disconnected from the push button switch 10, which improves the convenience of replacing the sealing sleeve 20 and avoids the sealing sleeve 20 and the push button switch 10 being replaced at the same time when the sealing sleeve 20 is damaged.

[0063] In this embodiment, the push-button switch 10 is elastically pressed relative to the water channel 200, so that the push-button switch 10 can move relative to the water channel 200 under human action. The push-button switch 10 can be maintained in an open or closed state. When the user presses the push-button switch 10 for the first time, the push-button switch 10 is in a closed state relative to the water channel 200, which facilitates the push-button switch 10 to drive the sealing sleeve 20 to disconnect the water channel 200. At the same time, water from the water channel 200 enters the annular cavity 20a, so that the water is arranged in a ring relative to the annular cavity 20a, making the sealing sleeve 20 pressurized in the annular direction and avoiding the pressure imbalance caused by only one end of the push-button switch 10 being pressurized, thus improving the pressing effect of the push-button switch 10 relative to the water channel 200 in the push-button switch assembly 100. When the user presses the push-button switch 10 for the second time, the push-button switch 10 is in an open state relative to the water channel 200, so that the water in the water channel 200 is in a flowing state.

[0064] In this embodiment, the push-button switch assembly 100 further includes an elastic element 30 and a locking element 40. The elastic element 30 is embedded in the water channel 200 and positioned connected to the water channel 200, ensuring the positional accuracy of the elastic element 30 relative to the water channel 200 and preventing the elastic element 30 from shifting position. The elastic element 30 elastically contacts the push-button switch 10 to apply an elastic force to the push-button switch 10, so that the push-button switch 10 can be elastically pressed relative to the water channel 200 through the elastic element 30.

[0065] The engaging component 40 connects to the push-button switch 10 and engages with the water channel 200 at the first position 210 and the second position 220 as the push-button switch 10 extends or retracts. This allows the push-button switch 10 to fix the engaging component 40 in either the first position 210 or the second position 220 of the water channel 200. When the push-button switch 10 is in the open state, the engaging component 40 engages with the first position 210 of the water channel 200, ensuring that the push-button switch 10 is positioned relative to the first position 210 of the water channel 200, thus ensuring that the water channel 200 is always in the open state and preventing automatic switching. When the push-button switch 10 is in the closed state, the engaging component 40 engages with the second position 220 of the water channel 200, ensuring that the push-button switch 10 is positioned relative to the second position 220 of the water channel 200, thus ensuring that the water channel 200 is always in the closed state and preventing automatic switching.

[0066] In this embodiment, the outer wall of the waterway 200 is provided with a track groove 200b, and the first position 210 and the second position 220 are respectively located in the track groove 200b; the first position 210 is lower than the second position 220 in the vertical direction; the track groove 200b is a unidirectional annular groove and is used to allow the engaging end of the engaging member 40 to move. The engaging end of the engaging member 40 moves unidirectionally along the track groove 200b so that the engaging member 40 can move along the track groove 200b and be arranged relative to the first position 210 or the second position 220 respectively, which improves the smoothness of the movement of the engaging member 40, and at the same time ensures the positional accuracy of the engaging member 40 relative to the first position 210 and the second position 220.

[0067] Optionally, the track groove 200b is arranged in a heart shape, with the first position 210 and the second position 220 distributed at both ends of the track groove 200b, allowing the engaging member 40 to move.

[0068] Specifically, the track groove 200b includes a first inclined groove 201b, a second inclined groove 202b, a third inclined groove 203b, and a fourth inclined groove 204b; the third inclined groove 203b connects to the first inclined groove 201b, and the fourth inclined groove connects to the second inclined groove 202b; when the push-button switch 10 switches from the open state to the closed state, the engaging member 40 starts from the first position 210 and moves along the second inclined groove 202b under human action. The engaging member 40 gradually disengages upward to the first position 210, passes the highest point of the second inclined groove 202b, and enters the fourth inclined groove 204b. Under the elastic force, the engaging member 40 moves along the fourth inclined groove 204b to the second position 220.

[0069] When the button switch 10 switches from the off state to the on state, the engaging member 40 starts from the second position 220 and moves along the third inclined groove 203b under human action. The engaging member 40 gradually disengages upward to the second position 220. The engaging member 40 passes the highest point of the third inclined groove 203b and enters the first inclined groove 201b. Under the elastic force, the engaging member 40 moves along the first inclined groove 201b to the first position 210.

[0070] The first inclined groove 201b and the second inclined groove 202b are disposed on both sides of the first position 210. The first inclined groove 201b and the second inclined groove 202b converge at the first position 210 along the inclined direction. The engaging member 40 moves downward along the first inclined groove 201b to the first position 210, and the engaging member 40 disengages upward along the second inclined groove 202b to the first position 210.

[0071] The third inclined groove 203b and the fourth inclined groove 204b are disposed on both sides of the second position 220. The third inclined groove 203b and the fourth inclined groove 204b converge at the second position 220 along the inclined direction. The engaging member 40 moves downward along the fourth inclined groove 204b to the second position 220, and the engaging member 40 disengages upward along the third inclined groove 203b to the second position 220.

[0072] Furthermore, the second inclined groove 202b is connected to the fourth inclined groove 204b and is arranged in a stepped manner;

[0073] The fourth inclined groove 204b and the third inclined groove 203b are arranged in a stepped manner;

[0074] The third inclined groove 203b is connected to the first inclined groove 201b and is arranged in a stepped manner;

[0075] The first inclined groove 201b and the four inclined grooves 204b are connected and arranged in a stepped manner. The stepped arrangement prevents the locking member 40 from moving in the opposite direction and ensures that the locking end of the locking member 40 moves unidirectionally along the track groove 200b. Optionally, the locking member 40 is a double-headed locking end, and there are two track grooves 200b, which are distributed on opposite side walls in the waterway 200. At the same time, the locking member 40 is an elastic component and presses against the bottom of the track groove 200b under the rebound action.

[0076] At this point, the stepped arrangement is mainly presented by corresponding steps 205b. The first inclined groove 201b, the second inclined groove 202b, the third inclined groove 203b, and the fourth inclined groove 204b are all provided with corresponding steps 205b. Steps 205b are generally located at the bottom of the first inclined groove 201b, the second inclined groove 202b, the third inclined groove 203b, or the fourth inclined groove 204b. The steps 205b create a corresponding height difference, preventing the engaging member 40 from moving in the opposite direction and ensuring that the engaging end of the engaging member 40 moves unidirectionally along the track groove 200b. Optionally, the steps 205b are arranged at an angle.

[0077] In a second embodiment, a shower head device includes a push-button switch assembly 100 and a water channel 200. The push-button switch 10 of the push-button switch assembly 100 is pressably connected to the water channel 200 of the shower head device to adjust the position of the push-button switch 10 relative to the water channel 200. The push-button switch 10 can be in an open or closed state relative to the water channel 200 to allow water to flow through or be disconnected, thereby saving water. The shower head device provides a comfortable showering experience.

[0078] At this time, the push-button switch assembly 100 includes a push-button switch 10 and a sealing sleeve 20. The push-button switch 10 is pressably connected to the water channel 200 of the shower head device, so that the water channel 200 is in an open or closed state. The sealing sleeve 20 is fitted onto the push-button switch 10 and is located inside the water channel 200. The sealing sleeve 20 has an annular cavity 20a, which is arranged along the periphery of the sealing sleeve 20. When the water channel 200 is in a closed state, the annular cavity 20a is connected to the first water passage cavity 200a inside the water channel 200 along its own annular direction. The first water passage cavity 200a is used to connect to the water inlet. The connection between the annular cavity 20a and the first water passage cavity 200a inside the water channel 200 will not cause any blockage or imbalance, so that the sealing sleeve 20 is pressurized in the annular direction. This avoids the push-button switch 10 being pressurized at only one end, which would result in an unbalanced pressure and improves the pressing effect of the push-button switch 10 relative to the water channel 200 in the push-button switch assembly 100.

[0079] Compared with the prior art, the beneficial effects of this utility model are:

[0080] This utility model provides a push-button switch assembly 100 and a shower head device. The push-button switch 10 is pressably connected to the water channel 200 of the shower head device, so that the water channel 200 is in an open or closed state. A sealing sleeve 20 is fitted onto the push-button switch 10 and is located inside the water channel 200. The sealing sleeve 20 has an annular cavity 20a, which is arranged along the periphery of the sealing sleeve 20. When the water channel 200 is in the closed state, the annular cavity 20a is connected to the first water passage cavity 200a inside the water channel 200 along its own annular direction. The first water passage cavity 200a is used to connect to the water inlet. The connection between the annular cavity 20a and the first water passage cavity 200a inside the water channel 200 will not cause blockage or imbalance, so that the sealing sleeve 20 is pressure balanced in the annular direction. This avoids the push-button switch 10 being pressured at only one end, which would cause pressure imbalance. This reduces the pressing force of the push-button switch 10 relative to the water channel 200, resulting in a better feel and operation.
