Description

Technical Field

[0001] This utility model relates to a two-function overhead shower head. Background Technology

[0002] Existing overhead showerheads (also known as shower heads) typically have only one water flow mode, although some may offer two or more. However, these showerheads usually use a switch (button or handle) on the showerhead itself for switching modes. Because overhead showerheads are installed at a considerable height, users need to use tools to elevate themselves to reach and activate the switch, making the process inconvenient and resulting in a poor user experience. Therefore, to enable remote switching of overhead showerhead modes, some existing technologies employ a hydraulic switching structure, utilizing water pressure to drive the switching. For example, the applicant's prior Chinese invention patent application, application number 2024103384238, entitled "A Hydraulic Switching Structure for an Overhead Showerhead with a Reset Function," addresses this issue.

[0003] However, existing overhead showerheads that use water pressure to switch water flow typically do not have a massage function, which cannot meet the increasingly diverse and personalized needs of users.

[0004] Therefore, it is necessary to provide a dual-function overhead shower head that has both water pressure switching function and massage water function. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to propose a dual-function overhead shower head that has both hydraulic switching function and massage water function, which has a simple structure and richer functions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A dual-function overhead shower head, comprising:

[0009] A hydraulic switching mechanism is provided in the main body. The hydraulic switching mechanism is subjected to the water pressure of the water inlet channel, which enables the water inlet channel to be selectively connected to the first water outlet channel or the second water outlet channel.

[0010] An alternating switching mechanism is provided in the main body and includes a guide vane and an impeller. The guide vane is provided with an inlet that communicates with the first water outlet channel. The impeller is configured to rotate in the main body due to the impact of the water flow formed through the inlet, thereby causing the several first water outlets to switch water output.

The water inlet channel is in fluid communication with the piston cylinder. When water flows into the piston cylinder through the water inlet channel, the reset piston moves under the water pressure in the piston cylinder, causing the energy storage spring to store energy. When water flows out of the piston cylinder through the water inlet channel, the energy storage spring releases the stored energy and resets through the hydraulic switching mechanism in conjunction with the reset piston. The reset piston and the energy storage spring constitute the energy storage component.

[0015] In a preferred embodiment, the piston cylinder is provided with a damping orifice, and the water inlet channel is in fluid communication with the piston cylinder through the damping orifice; the piston cylinder is also provided with a flow passage with a flow cross-sectional area larger than that of the damping orifice, and a one-way valve is provided at the flow passage to allow the water flow from the water inlet channel to flow unidirectionally into the piston cylinder.

[0022] In a preferred embodiment, the body is provided with a first valve port located between the water inlet channel and the first water outlet channel, and a second valve port located between the water inlet channel and the second water outlet channel. In the first switching position, the switching shaft opens the first valve port and closes the second valve port.

[0026] This invention incorporates a hydraulic switching mechanism and an alternating switching mechanism within the body of the overhead showerhead. The hydraulic switching mechanism, acting on the water pressure of the inlet channel, allows the inlet channel to selectively connect to either a first or second outlet channel, thus achieving hydraulic switching. The alternating switching mechanism includes a guide vane and an impeller. The guide vane has an inlet connected to the first outlet channel, and the impeller is configured to rotate within the body due to the impact of the water flow generated at the inlet, thereby switching the water output from several first outlets to achieve a massage water function.

[0046] To make the technical problem to be solved, the technical solution, and the beneficial effects of this 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 this utility model and are not intended to limit this utility model.

[0047] Please see Figures 1 to 12 A preferred embodiment of the present invention provides a two-function overhead shower head, comprising a body 10, a water switching mechanism 20, and an alternating switching mechanism 30, wherein:

[0048] The main body 10 has a water inlet channel 11, a first water outlet channel 12, a second water outlet channel 13, a plurality of first water outlets 171 and at least one second water outlet 172. The first water outlet channel 12 is connected to the first water outlet 171, and the second water outlet channel 13 is connected to the second water outlet 172.

[0049] The hydraulic switching mechanism 20 is located inside the main body 10. The hydraulic switching mechanism 20 is subjected to the water pressure of the water inlet channel 11, which enables the water inlet channel 11 to be selectively connected to the first water outlet channel 12 or the second water outlet channel 13.

[0050] The alternating switching mechanism 30 is located inside the body 10 and includes a guide vane 31 and an impeller 32. The guide vane 31 is provided with an inlet 311 that is connected to the first water outlet channel 12. The impeller 32 is configured to rotate inside the body 10 due to the impact of the water flow formed through the inlet 311, thereby causing several first water outlets 171 to switch water outlets.

[0051] By incorporating a hydraulic switching mechanism 20 and an alternating switching mechanism 30 within the body 10 of the overhead showerhead, the hydraulic switching mechanism 20, under the water pressure of the inlet channel 11, allows the inlet channel 11 to selectively connect with either the first outlet channel 12 or the second outlet channel 13, thus achieving a hydraulic switching function. The alternating switching mechanism 30 includes a guide vane 31 and an impeller 32. The guide vane 31 has an inlet 311 connected to the first outlet channel 12, and the impeller 32 is configured to rotate within the body 10 due to the impact of the water flow generated through the inlet 311, thereby causing several first outlets 171 to switch water flow, thus achieving a massage water function. In this way, the overhead showerhead possesses both a hydraulic switching function and a massage water function, offering richer functionality while maintaining a simple structure.

[0052] Specifically, in this embodiment, the main body 10 includes, from top to bottom, an upper cover 14, a first water distribution plate 15, a second water distribution plate 16, a water outlet plate 17, and a face cover 18. The upper cover 14 and the first water distribution plate 15 form a receiving cavity 141, within which the hydraulic switching mechanism 20 and the alternating switching mechanism 30 are disposed. The first water distribution plate 15 and the second water distribution plate 16 form a portion of a mutually sealed and isolated first water outlet channel 12 and a first water outlet cavity 151. The first water outlet cavity 151 includes a mutually sealed and isolated first alternating cavity 1511 and a second alternating cavity 1512. A portion of the plurality of first water outlets 171 communicates with the first alternating cavity 1511, and another portion communicates with the second alternating cavity 1512. The impeller 32 is equipped with a sealing part 321 that switches between blocking the inlet 15111 of the first alternating chamber 1511 and the inlet 15121 of the second alternating chamber 1512. By switching between blocking the inlet 15111 of the first alternating chamber 1511 and the inlet 15121 of the second alternating chamber 1512, water flow is switched between the first outlet 171 connected to the first alternating chamber 1511 and the first outlet 171 connected to the second alternating chamber 1512, thus creating a pulse in the water flow and providing a massage effect. The second water distribution plate 16 and the water outlet plate 17 form a second water outlet chamber 161 that communicates with the second water outlet channel 13, and the second water outlet 172 communicates with the second water outlet chamber 161. The first water outlet 171 and the second water outlet 172 are both located on the water outlet plate 17, and the cover 18 is provided with clearance holes 181 for the first water outlet 171 and the second water outlet 172 to pass through. Through the above structural design, the internal structure of the body 10 is very simple, compact, and has a reasonable and ingenious layout.

[0053] Specifically, in this embodiment, the first water distribution plate 15, the second water distribution plate 16, the water outlet plate 17, and the cover 18 are fixedly connected as an integral structure by a plurality of screws 19. The first water distribution plate 15 is provided with a first screw clearance hole 152, the second water distribution plate 16 is provided with a second screw clearance hole 162, the water outlet plate 17 is provided with a third screw clearance hole 173, and the cover 18 is provided with a stud 183. Each screw 19 passes through the first screw clearance hole 152, the second screw clearance hole 162, and the third screw clearance hole 173 respectively and is threadedly connected to the corresponding stud 183. The upper cover 14 is provided with a peripheral wall, and the inner side of the peripheral wall of the upper cover 14 is provided with a plurality of first buckles 142 spaced apart. The periphery of the cover 18 is provided with a plurality of second buckles 182 spaced apart. The upper cover 14 and the cover 18 are fixed together by the first buckles 142 and the second buckles 182.

[0054] In this embodiment, a reset mechanism 40 is also provided in the main body 10. The reset mechanism 40 controls the hydraulic switching mechanism 20 to reset to the initial state. In the initial state, the water inlet channel 11 is connected to the first water outlet 171 through the first water outlet channel 12. The reset mechanism 40 specifically includes an energy storage component. The energy storage component stores energy using the water pressure of the water inlet channel 11. When the energy storage component releases the stored energy, it resets the hydraulic switching mechanism 20.

[0055] Specifically, in this embodiment, both the reset mechanism 40 and the hydraulic switching mechanism 20 directly adopt the structure of the prior Chinese patent (application number 2024103384238, patent name "a hydraulic switching structure for a top spray shower with reset function"). The following is only a brief description of the reset mechanism 40 and the hydraulic switching mechanism 20. Their more specific structures and working principles are referred to the aforementioned prior patent.

[0056] Reset mechanism 40:

[0057] The reset mechanism 40 includes a piston cylinder 41, a reset piston 42 cooperating with the piston cylinder 41, and an energy storage spring 43 cooperating with the reset piston 42. The water inlet channel 11 is in fluid communication with the piston cylinder 41. When water flows into the piston cylinder 41 through the water inlet channel 11, the reset piston 42 moves under the water pressure inside the piston cylinder 41, causing the energy storage spring 43 to store energy. When water flows out of the piston cylinder 41 through the water inlet channel 11, the energy storage spring 43 releases its stored energy and resets through the hydraulic switching mechanism 20 in conjunction with the reset piston 42. The reset piston 42 and the energy storage spring 43 constitute an energy storage component. The piston cylinder 41 is provided with a damping hole 4111, through which the water inlet channel 11 is in fluid communication with the piston cylinder 41. The piston cylinder 41 is also provided with a flow passage with a cross-sectional area larger than that of the damping hole 4111, and a one-way valve 411 is provided at the flow passage to allow water from the water inlet channel 11 to flow unidirectionally into the piston cylinder 41. The large flow cross-sectional area of ​​the flow passage allows the incoming water to quickly fill the piston cylinder 41, thereby driving the reset piston 42 away from the switching shaft 21 described below as soon as possible, and preventing it from interfering with the movement of the switching shaft 21 from the first switching position to the second switching position. On the other hand, the small flow cross-sectional area of ​​the damping orifice 4111 prevents the water in the piston cylinder 41 from flowing out quickly during continuous switching, thus keeping the reset piston 42 in a position away from the switching shaft 21, so as to achieve normal continuous switching operation.

[0058] Unlike the prior patents mentioned above, where the damping orifice and flow passage are set relatively independently, in this embodiment, the damping orifice 4111 is preferably set directly on the one-way valve 411. This eliminates the need to open a separate hole on the piston cylinder 41 as the damping orifice 4111, and only one flow passage needs to be opened on the piston cylinder 41, resulting in a simpler structure.

[0059] It is understandable that, in addition to adopting the structure of the aforementioned Chinese patent, the reset mechanism 40 can also be replaced by an existing known reset mechanism 40, as long as it can drive the switching shaft 21 to reset from the second switching position to the first switching position after the water inlet channel 11 is cut off for a predetermined period of time. These are not listed in detail here.

[0060] Hydraulic switching mechanism 20:

[0061] The hydraulic switching mechanism 20 adopts a reciprocating hydraulic switching mechanism, specifically including:

[0062] A switching shaft 21 is provided on the body 10 and can slide between a first switching position and a second switching position so that the water inlet channel 11 is switched to connect the first water outlet channel 12 and the second water outlet channel 13. The reset mechanism 40 cooperates with the switching shaft 21 to drive the switching shaft 21 to reset from the second switching position to the first switching position.

[0063] The swing block 22 is mounted on the switching shaft 21 and can swing between the first swing position and the second swing position;

[0064] The swing drive (not shown) is movably mounted on the body 10. When the swing block 22 moves to the first switching position or the second switching position with the switching shaft 21 and the water inlet channel 11 is cut off, the swing drive can drive the swing block 22 to swing between the first swing position and the second swing position.

[0065] A hydraulic drive component 23 is movably mounted on the main body 10 and driven by the pressure of the water inlet channel 11. The hydraulic drive component 23 cooperates with the swing block 22. There is a first guide slope and a second guide slope between the hydraulic drive component 23 and the swing block 22. When the swing block 22 is in the first swing position, the hydraulic drive component 23 can cooperate with the swing block 22 through the first guide slope to drive the switching shaft 21 from the first switching position to the second switching position. When the swing block 22 is in the second swing position, the hydraulic drive component 23 can cooperate with the swing block 22 through the second guide slope to drive the switching shaft 21 from the second switching position to the first switching position. The hydraulic drive component 23 includes a piston 231 and a pressure block 232. The piston 231 and the pressure block 232 are in abutting and transmission cooperation, and the pressure block 232 cooperates with the swing block 22.

[0066] It is understandable that, in addition to adopting the structure of the aforementioned Chinese patent, the hydraulic switching mechanism 20 can also be replaced by existing known hydraulic switching mechanisms 20, which will not be listed in detail here.

[0067] In this embodiment, the main body 10 is provided with a first valve port 111 located between the water inlet channel 11 and the first water outlet channel 12, and a second valve port 112 located between the water inlet channel 11 and the second water outlet channel 13. In the first switching position, the switching shaft 21 opens the first valve port 111 and closes the second valve port 112. In the second switching position, the switching shaft 21 opens the second valve port 112 and closes the first valve port 111.

[0068] In this embodiment, a water passage cavity 121 communicating with the first water outlet channel 12 is formed inside the main body 10. The guide vane 31 and the impeller 32 are disposed in the water passage cavity 121. The water inlet 311 extends obliquely to form an oblique water flow impacting the impeller 32. The bottom of the water passage cavity 121 is provided with the inlet 15111 of the first alternating cavity 1511 and the inlet 15121 of the second alternating cavity 1512.

[0069] In this embodiment, the inlet 15111 of the first alternating cavity 1511 and the inlet 15121 of the second alternating cavity 1512 are symmetrically arranged. The impeller 32 is arranged with multiple blades in an array along the circumferential direction. The bottom of some adjacent blades is open to form a water passage, and the bottom of other adjacent blades is closed to form a sealing part 321. The area of ​​the water passage is larger than the area of ​​the sealing part 321 to ensure that the water outlets of the first outlet 171 and the second outlet 172 are continuous and will not stop. Multiple inlets 311 are arranged in an array along the circumferential direction of the guide vane 31 so that the formed oblique water flow can reliably drive the impeller 22 to rotate.

[0070] The working process of this embodiment is briefly described as follows:

[0071] See Figure 9 At this time, the water inlet channel 11 of the main body 10 is not filled with water, the switching shaft 21 of the hydraulic switching mechanism 20 is in the initial position, that is, the first switching position, the switching shaft 21 opens the first valve port 111 and closes the second valve port 112, the reset piston 42 of the reset mechanism 40 abuts against the switching shaft 21, so that the switching shaft 21 is kept in the first switching position, and the swing block 22 is in the first swing position.

[0072] See Figure 10 ,exist Figure 9 In this state, water enters through the water inlet channel 11. The water pressure from the water flow in the water inlet channel 11 drives the piston 231 to move. The piston 231 drives the pressure block 232 to move towards the swing block 22. When the first guide slope on the pressure block 232 engages with the first guide slope on the swing block 22, the pressure block 232 begins to drive the switching shaft 20 to move from the first switching position to the second switching position, until it reaches the second switching position. Figure 10As shown in the figure, at this time, the switching shaft 20 is in the second switching position. The switching shaft 20 opens the second valve port 112 and closes the first valve port 111. The second valve port 112 supplies water to the second water outlet 172 through the second water outlet channel 13. At the same time, another part of the water flow in the inlet channel 11 enters the piston cylinder 41 through the one-way valve 411. The reset piston 42 is compressed by the water pressure to the energy storage spring 43. The energy storage spring 43 is in the energy storage state. The reset piston 42 no longer abuts against the switching shaft 20, so it will not interfere with the movement of the switching shaft 20. The switching shaft 20 can be maintained in the second switching position under the action of the inlet water pressure.

[0073] See Figure 11 and Figure 12 ,exist Figure 10 In this state, after the water inlet channel 11 is cut off and then reopened, the piston 231 drives the switching shaft 20 to move from the second switching position to the first switching position through the pressure block 232, until it reaches the first switching position. Figure 11 The position shown is such that, at this time, the switching shaft 20 is in the first switching position, the switching shaft 20 closes the second valve port 112 and opens the first valve port 111, and the first valve port 111 supplies water to the water passage chamber 121 through the first water outlet channel 12, as shown. Figure 12 As shown, the water in the water passage 121 impacts the impeller 32 obliquely through the water inlet 311 on the guide vane 31, causing the impeller 32 to rotate inside the body 10, thereby causing the first water outlet 171 of the first alternating cavity 1511 and the first water outlet 171 of the second alternating cavity 1512 to switch water output, thus realizing the massage water function.

[0074] exist Figure 10 In the water outlet state shown, after the overhead shower is used and the water inlet channel 11 is shut off for a predetermined time, the water in the piston cylinder 41 can flow out through the damping hole 4111. The reset piston 42 is reset under the elastic force of the energy storage spring 43, and the reset piston 42 can then drive the switching shaft 20 to reset from the second switching position to the first switching position; Figure 11 In the water outlet state shown, after the overhead shower is used and the water inlet channel 11 is shut off for a predetermined time, the water in the piston cylinder 41 can flow out through the damping hole 4111. The reset piston 42 is reset under the elastic force of the energy storage spring 43, and the reset piston 42 can then re-abut against the switching shaft 20, so that the switching shaft 20 remains in the first switching position. That is to say, no matter what water outlet state the overhead shower is in when it is stopped, the overhead shower can be reset to the initial state. The next time the water inlet channel 11 is reopened for water intake, it will still default to the second water outlet 172 to output non-massage water, such as ordinary granular water (e.g., Figure 10 As shown), the system switches to the first outlet 171 to dispense massage water only when the water inlet channel 11 is closed and then reopened shortly after the water supply is interrupted (as shown). Figure 11 and Figure 12 (As shown). In other words, in this embodiment, water always flows from the second outlet 172 by default when the overhead shower is turned on. It is understandable that in other embodiments, it can be replaced by the following: in the first switching position, the switching shaft 21 closes the first valve port 111 and opens the second valve port 112; in the second switching position, the switching shaft 21 closes the second valve port 112 and opens the first valve port 111. After this replacement, water will always flow from the first outlet 171 by default when the overhead shower is turned on. The specific choice can be made according to needs.
