Description

Technical Field

[0001] This invention relates to a water pressure switching structure for a shower head. Background Technology

[0002] Most showerheads on the market can only produce one type of water flow from the same outlet. In order to provide users with multiple water flow modes, multiple outlets are usually set up, with each outlet producing a corresponding water flow. However, the existing solution requires each outlet to be set up independently, which takes up space on the water outlet panel. This results in the water outlet panel usually needing to be designed to be large enough to accommodate multiple outlets, and also leads to a poor user experience when showering. Summary of the Invention

[0003] The purpose of this invention is to provide a water pressure switching structure for a shower head, which can form a first water outlet mode and a second water outlet mode on the same outlet. The structure is simple and the effect is reliable.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A water pressure switching structure for a shower head includes:

[0006] The main body has an inlet, a first outlet, and a first waterway and a second waterway respectively connected to the first outlet.

[0007] A switching structure is used to switch the connection between the water inlet and the first waterway and the second waterway;

[0008] The movable component is movably disposed within the body between the first position and the second position. When the water inlet is connected to the first water channel, the movable component moves to the first position under the water flow pressure of the first water channel so that the first water outlet discharges water in the first water outlet mode. When the water inlet is connected to the second water channel, the movable component is located in the second position so that the first water outlet discharges water in the second water outlet mode.

[0009] Preferably, the movable component moves from the first position to the second position under the action of the restoring force, wherein the restoring force is the elastic force provided by the elastic component, the magnetic force provided by the magnetic component, the gravity provided by the movable component itself, or the water flow pressure provided by the second waterway.

[0010] Preferably, the outlet end of the first water channel forms a piston chamber, and the movable member is provided with a protrusion extending into the piston chamber. The protrusion is used to withstand the water flow pressure provided by the first water channel so that the movable member moves to the first position; the movable member is provided with a water flow clearance hole corresponding to the outlet end of the second water channel.

[0011] Preferably, the piston chamber includes a piston chamber inlet and a piston chamber outlet disposed opposite to each other. The protrusion of the movable member enters and exits the piston chamber through the piston chamber outlet, and the cross-sectional area of ​​the piston chamber outlet is larger than the cross-sectional area of ​​the piston chamber inlet.

[0012] Preferably, the main body includes a water outlet panel with a plurality of first water outlets. The movable component is a needle plate with a plurality of needles corresponding one-to-one with the first water outlets. When the movable component is in the first position, the needles are inserted into the first water outlets, and water flows out through a first gap formed between the outer wall of the needle and the inner wall of the first water outlet. At this time, the flow cross-sectional area of ​​the first water outlet is small. When the movable component is in the second position, the needles are completely withdrawn from the first water outlets, or the needles are partially withdrawn from the first water outlets, forming a second gap between the outer wall of the needle and the inner wall of the first water outlet. The flow cross-sectional area of ​​the second gap is larger than that of the first gap. At this time, the flow cross-sectional area of ​​the first water outlet is larger.

[0013] Preferably, the movable component is provided with an inclined water body. When the movable component is in the first position, the inclined water body cooperates with the first water outlet, so that the water flow in the first water channel enters the first water outlet at a predetermined angle under the guidance of the inclined water body and flows out in a rotating manner along the inner wall of the first water outlet; when the movable component is in the second position, the inclined water body is away from the first water outlet.

[0014] Preferably, the main body includes a water outlet panel, the water outlet panel is provided with a plurality of first water outlets, the movable component is a needle plate, the needle plate is provided with a plurality of needles corresponding one-to-one with the first water outlets.

[0015] Preferably, the main body includes a water distribution plate and a water outlet panel. The water distribution plate is provided with a first water channel and a second water channel. The water outlet panel is provided with a first water outlet. The movable component is a disc-shaped structure and is movably disposed in the cavity formed between the water distribution plate and the water outlet panel. The restoring force is the elastic force provided by the elastic component, and the elastic component elastically abuts against the movable component and the water outlet panel.

[0016] Preferably, the water distribution plate, the movable part, and the water outlet panel are an integral structure forming the switching structure. The main body includes a shell with a water inlet channel. The switching structure is rotatably mounted on the shell. The water inlet forms the inlet end of the water inlet channel. The outlet end of the water inlet channel is provided with a sealing gasket. The side of the water distribution plate facing away from the water outlet panel is provided with a first flow hole and a second flow hole. The first flow hole forms the inlet of the first water channel, and the second flow hole forms the inlet of the second water channel. When the switching structure rotates, the outlet end of the water inlet channel is alternately sealed and connected with the first flow hole and the second flow hole.

[0017] Preferably, the water distribution plate and the water outlet panel are fixedly installed, and the switching structure is movably installed within the main body.

[0018] Preferably, the water distribution plate is further provided with a third water channel, and the water outlet panel is further provided with a second water outlet connected to the third water channel. The switching structure switches between connecting the water inlet to the first water channel, the second water channel and the third water channel.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] This invention incorporates a movable component within the main body, allowing the component to move between a first position and a second position. When the inlet is connected to the first water channel, the movable component moves to the first position under the pressure of the water flow in the first water channel, enabling the first outlet to output water in the first water outlet mode. When the inlet is connected to the second water channel, the movable component moves to the second position under the action of a restoring force, enabling the first outlet to output water in the second water outlet mode. In this way, the water outlet mode of the first outlet can be switched using water pressure, allowing the first outlet to output water in both the first and second water outlet modes. That is, the shower head's water pressure switching structure can form two water outlet modes on the same outlet, resulting in a simple structure and reliable performance.

[0021] 2. The outlet end of the first water channel forms a piston chamber. The movable part is provided with a protrusion that extends into the piston chamber. The protrusion is used to withstand the water flow pressure provided by the first water channel so that the movable part can move to the first position. This design can more cleverly utilize the water flow pressure of the first water channel to drive the movable part, which can effectively reduce the requirements for driving water pressure, making the product applicable to lower inlet water pressure and wider range of applications.

[0022] 3. The moving part is equipped with a needle. By inserting or withdrawing the needle (including full withdrawal and partial withdrawal) into the first water outlet, the size of the flow cross-sectional area of ​​the first water outlet is changed, thereby realizing the switching between the pressurized and normal pressure water outlet modes of the first water outlet. The structure is simple and the function is reliable.

[0023] 4. The movable part is equipped with an inclined water body. When the movable part is in the first position, the inclined water body cooperates with the first water outlet, so that the water flow in the first water channel enters the first water outlet at a predetermined angle under the guidance of the inclined water body and flows out in a rotating manner along the inner wall of the first water outlet, thereby realizing the rotating water outlet mode (first water outlet mode); when the movable part is in the second position, the inclined water body moves away from the first water outlet, thereby realizing the columnar water outlet mode (second water outlet mode), thus realizing the switching between the two water outlet modes of the first water outlet. The structure is simple and the function is reliable.

[0024] 5. The water distribution plate, movable parts and water outlet panel are integrated into a single structure to form the switching structure, which makes the overall structure of the shower head more compact and simple. Attached Figure Description

[0048] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention 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 merely illustrative and not intended to limit the scope of the invention.

[0049] In the discussion below, details are provided to provide a more thorough understanding of the invention. However, those skilled in the art will appreciate that the invention can be practiced without one or more of these details. In certain examples, some technical features well-known in the art have not been described in detail to avoid confusion with the invention. It should be noted that the terms “upper,” “lower,” “front,” “rear,” “left,” “right,” and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0050] The ordinal numbers such as "first" and "second" used in this invention are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term "first component" does not imply the existence of "second component," and the term "second component" does not imply the existence of "first component."

[0051] Please refer to Figures 1 to 13 A preferred embodiment of the present invention provides a water pressure switching structure for a shower head, comprising a body 10, a movable member 20, and a switching structure. The body 10 has an inlet 11, a first outlet 131, and a first water channel 121 and a second water channel 122 respectively connected to the first outlet 131. The switching structure is used to switchly control the connection between the inlet 11 and the first water channel 121 and the second water channel 122. The movable member 20 is movably disposed within the body 10 between a first position and a second position. When the inlet 11 is connected to the first water channel 121, the movable member 20 moves to the first position under the water pressure of the first water channel 121, so that the first outlet 131 outputs water in a first water output mode. When the inlet 11 is connected to the second water channel 122, the movable member 20 is located in the second position, so that the first outlet 131 outputs water in a second water output mode. In this way, the water outlet 131 can be switched by water pressure, so that the first water outlet 131 can spray water in both the first water outlet mode and the second water outlet mode. That is, the water pressure switching structure of the shower head can form two water outlet modes on the same water outlet. The structure is simple and the effect is reliable.

[0052] Under the action of the restoring force, the movable component 20 moves from the first position to the second position. The restoring force can be the elastic force provided by the elastic component 30, the magnetic force provided by the magnetic component, the gravity provided by the movable component 20 itself, or the water flow pressure provided by the second waterway 122, etc. In this embodiment, the elastic force provided by the elastic component 30 is specifically used as the restoring force. The elastic component 30 is a compression spring, but it can also be other forms of elastic components, such as a tension spring or a leaf spring, etc.

[0053] In this embodiment, a piston chamber 1211 is formed at the outlet end of the first water channel 121. The movable member 20 has a protrusion 21 extending into the piston chamber 1211. The protrusion 21 is used to withstand the water pressure provided by the first water channel 121, allowing the movable member 20 to move to the first position. This design cleverly utilizes the water pressure of the first water channel 121 to drive the movable member 20, effectively reducing the requirement for driving water pressure and allowing the product to be used with lower inlet water pressure and a wider range of applications. A water flow clearance hole 22 is provided on the movable member 20 at the outlet end 1222 of the second water channel 122. The water flow clearance hole 22 prevents the movable member 20 from being driven by the water pressure of the second water channel 122. See also... Figure 2 and Figure 3 In this embodiment, the outlet end (piston chamber 1211) of the first water channel 121 is provided with 7 circumferentially spaced outlets, and the outlet end 1222 of the second water channel 122 is provided with 10 circumferentially spaced outlets, with the 10 outlet ends 1222 of the second water channel 122 surrounding the 7 outlet ends (piston chambers 1211) of the first water channel 121. The outlet ends 1222 of the first water channel 121 and the outlet ends 1222 of the second water channel 122 are both located on the second plate portion 12b of the water distribution plate 12 described below.

[0054] In this embodiment, the piston chamber 1211 includes a water inlet end and a water outlet end of the piston chamber 1211 arranged opposite to each other. The protrusion 21 of the movable member 20 enters and exits the piston chamber 1211 through the water outlet end of the piston chamber 1211. The cross-sectional area of ​​the water outlet end of the piston chamber 1211 is larger than the cross-sectional area of ​​the water inlet end of the piston chamber 1211.

[0055] In this embodiment, the main body 10 includes a water outlet panel 13, which has a plurality of first water outlets 131. The movable component 20 is a needle plate, which has a plurality of needles 23 corresponding one-to-one with the first water outlets 131. Figure 8 , Figure 9 , Figures 11 to 13As shown, when the movable part 20 is in the first position, the needle 23 is inserted into the first outlet 131, and the water flows out through the first gap formed between the outer wall of the needle 23 and the inner wall of the first outlet 131. At this time, the flow cross-sectional area of ​​the first outlet 131 is small, which can increase the water pressure flowing out of the first outlet 131. That is, the first outlet 131 is in the pressurized water outlet mode (first water outlet mode) at this time. Figure 6 and Figure 7 As shown, when the movable member 20 is in the second position, the needle 23 partially retracts from the first outlet 131, forming a second gap between the outer wall of the needle 23 and the inner wall of the first outlet 131. The flow cross-sectional area of ​​the second gap is larger than that of the first gap. Therefore, the flow cross-sectional area of ​​the first outlet 131 is larger, meaning that the first outlet 131 is in normal pressure water outlet mode (second water outlet mode). Alternatively, in some other embodiments, when the movable member 20 is in the second position, the needle 23 can also be completely retracted from the first outlet 131, thereby increasing the flow cross-sectional area of ​​the first outlet 131. Thus, by providing the needle 23 on the movable member 20, and by inserting or retracting (including completely and partially retracting) the needle 23 into or out of the first outlet 131 to change the size of the flow cross-sectional area of ​​the first outlet 131, the switching between pressurized and normal pressure water outlet modes of the first outlet 131 can be achieved. The structure is simple and the function is reliable.

[0056] In this embodiment, the main body 10 includes a water outlet panel 13, which has a plurality of first water outlets 131. The movable component 20 is a disc-shaped needle plate, which has a plurality of needles 23 corresponding to the first water outlets 131.

[0057] In this embodiment, the main body 10 also includes a water distribution plate 12, on which a first water channel 121 and a second water channel 122 are provided. The movable member 20 is movably disposed in the cavity formed between the water distribution plate 12 and the water outlet panel 13, and the elastic member 30 elastically abuts against the movable member 20 and the water outlet panel 13.

[0058] In this embodiment, the water distribution plate 12, the movable part 20, and the water outlet panel 13 are an integral structure forming the switching structure. The main body 10 includes a shell 14 with a water inlet channel 141. The switching structure is rotatably mounted on the shell 14. The water inlet 11 forms the inlet end of the water inlet channel 141, and the outlet end of the water inlet channel 141 is provided with a sealing gasket 1411. The side of the water distribution plate 12 facing away from the water outlet panel 13 is provided with a first flow hole 1212 and a second flow hole 1221. The first flow hole 1212 forms the inlet of the first water channel 121, and the second flow hole 1221 forms the inlet of the second water channel 122. When the switching structure rotates, the outlet end of the water inlet channel 141 is switched to be sealed and connected with the first flow hole 1212 and the second flow hole 1221.

[0059] In order to enable the switching structure to be rotated more effectively, in this embodiment, a toggle switch 133 is also provided on the water outlet panel 13. When the toggle switch 133 is driven, the entire switching structure (including the water distribution plate 12, the movable part 20 and the water outlet panel 13) can be rotated, thereby realizing the water path switching.

[0060] In this embodiment, the water distribution plate 12 is further provided with a third water channel 123, and the water outlet panel 13 is also provided with a second water outlet 132 connected to the third water channel 123. The switching structure switches between the water inlet 11 and the first water channel 121, the second water channel 122, and the third water channel 123. A third flow hole 1231 is provided on the side of the water distribution plate 12 facing away from the water outlet panel 13, and the third flow hole 1231 forms the inlet of the third water channel 123. The setting of the second water outlet 132 can make the water outlet mode of the shower head more diverse. For example, the second water outlet 132 can flow out atomized water, sheet water, or massage water, etc. Specifically, the water distribution plate 12 includes a first plate part 12a and a second plate part 12b. The first plate part 12a and the second plate part 12b are fixedly connected by welding and form the first water channel 121, the second water channel 122, and the third water channel 123.

[0061] In other embodiments, the switching structure may not necessarily consist of the water distribution plate 12, the movable component 20, and the water outlet panel 13 together. Instead, the switching structure (not shown) may be set independently of the water distribution plate 12 and the water outlet panel 13. In this case, the water distribution plate 12 and the water outlet panel 13 can be fixedly installed, while the switching structure is movably installed within the main body 10. For example, the switching structure can be a common structure in the art, such as a switching shaft. The specific structure of the switching structure can be set as needed and is not limited thereto, as long as it can switch the water path.

[0062] The working principle of this embodiment is briefly described as follows:

[0063] See Figure 6 and Figure 7 As shown, at this time, the second flow hole 1221 of the water distribution plate 12 is sealed and connected to the outlet end of the water inlet channel 141. That is, the water inlet 11 is connected to the second water channel 122, and water flows through the second water channel 122. Since the outlet end 1222 of the second water channel 122 corresponds to the water flow clearance hole 22 on the movable member 20, the water flow clearance hole 22 prevents the movable member 20 from being driven by the water flow pressure of the second water channel 122. The movable member 20 is in the second position under the action of the elastic force provided by the elastic member 30. At this time, the needle part 23 on the movable member 20 partially exits the first water outlet 131, and a second gap is formed between the outer wall of the needle part 23 and the inner wall of the first water outlet 131. The flow cross-sectional area of ​​the second gap is large, that is, the flow cross-sectional area of ​​the first water outlet 131 is large. At this time, the first water outlet 131 is in normal pressure water outlet mode.

[0064] See Figures 8 to 13 As shown, at this time, the first flow hole 1212 of the water distribution plate 12 is sealed and connected to the outlet end of the water inlet channel 141. That is, the water inlet 11 is connected to the first water channel 121, and water flows through the first water channel 121. Since the outlet end (piston chamber 1211) of the first water channel 121 corresponds to the protrusion 21 on the movable member 20, the protrusion 21 is subjected to the water flow pressure provided by the first water channel 121, causing the movable member 20 to move to the first position. At this time, the needle 23 on the movable member 20 is inserted into the first water outlet 131, and the water flows out through the first gap formed between the outer wall of the needle 23 and the inner wall of the first water outlet 131. The flow cross-sectional area of ​​the first gap is small, that is, the flow cross-sectional area of ​​the first water outlet 131 is small, which can increase the water flow pressure of the first water outlet 131. That is, the first water outlet 131 is in the pressurized water outlet mode at this time.

[0065] Please refer to Figures 14 to 18 Another preferred embodiment of the present invention provides a water pressure switching structure for a shower head. The main difference between this embodiment and the one described above is the structure of the movable component 20, which results in different water outlet modes for the first outlet 131. Specifically, in this embodiment, the movable component 20 does not have a needle 23; instead, it is replaced by an inclined water body 24. By providing the inclined water body 24 on the movable component 20, the first outlet 131 achieves both a rotating water outlet mode and a columnar water outlet mode. Specifically, when the movable component 20 is in the first position, the inclined water body 24 cooperates with the first outlet 131, causing the water flow from the first water channel 121 to enter the first outlet 131 at a predetermined angle under the guidance of the inclined water body 24 and flow out rotatingly along the inner wall of the first outlet 131, resulting in rotating water flowing out of the first outlet 131 (i.e., the first water outlet mode is the rotating water outlet mode). See details... Figures 14 to 16 When the movable part 20 is in the second position, the inclined water body 24 moves away from the first outlet 131 so that columnar water flows out of the first outlet 131 (i.e., the second water outlet mode is the columnar water outlet mode), see details. Figure 17 and Figure 18 .

[0066] The working principle of this embodiment is briefly described as follows:

[0067] See Figure 15 and Figure 16As shown, at this time, the first flow hole 1212 of the water distribution plate 12 is sealed and connected to the outlet end of the water inlet channel 141. That is, the water inlet 11 is connected to the first water channel 121, and water flows through the first water channel 121. Since the outlet end (piston chamber 1211) of the first water channel 121 corresponds to the protrusion 21 on the movable member 20, the protrusion 21 is subjected to the water flow pressure provided by the first water channel 121, so that the movable member 20 moves to the first position. At this time, the inclined water body 24 cooperates with the first water outlet 131, so that the water flow of the first water channel 121 enters the first water outlet 131 at a predetermined angle under the guidance of the inclined water body 24 and flows out in a rotating manner along the inner wall of the first water outlet 131, so that rotating water flows out of the first water outlet 131 (that is, the first water outlet mode is the rotating water outlet mode).

[0068] See Figure 17 and Figure 18 As shown, at this time, the second flow hole 1221 of the water distribution plate 12 is sealed and connected to the outlet end of the water inlet channel 141. That is, the water inlet 11 is connected to the second water channel 122, and water flows through the second water channel 122. Since the outlet end 1222 of the second water channel 122 corresponds to the water flow clearance hole 22 on the movable member 20, the water flow clearance hole 22 prevents the movable member 20 from being driven by the water flow pressure of the second water channel 122. The movable member 20 is in the second position under the action of the elastic force provided by the elastic member 30. At this time, the inclined water body 24 moves away from the first water outlet 131 so that the first water outlet 131 flows out of the columnar water (that is, the second water outlet mode is the columnar water outlet mode).
