Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, specifically a push-button switching structure and water outlet component. Background Technology

[0002] In modern bathroom product design, the versatility and ease of use of water outlet devices have become important research and development directions, especially in showerheads and overhead sprayers, where users increasingly demand different water spray effects. These different water spray effects are usually achieved by changing the water flow path through a switching mechanism, thereby meeting users' personalized needs. However, existing switching mechanisms have many shortcomings. For example, the traditional ballpoint pen-style switching mechanism mainly relies on ratchet and ratchet teeth to switch water flow. Although the structure is compact, its complex design leads to high manufacturing costs, and it is prone to jamming after long-term use. In addition, the toggle-style switching mechanism achieves water flow switching by moving the toggle along an arc trajectory. Although the operation is intuitive, it requires a lot of force, resulting in a poor user experience. More importantly, the water functions of showerheads and spray guns are often separate products in the current market, making it difficult to effectively integrate their functions. Even in some products that attempt to integrate the spray gun function into the showerhead, the spray gun water mode is relatively simple and cannot meet users' actual needs for diverse spray gun water output. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a push-button switching structure and a water outlet component.

[0004] This utility model is achieved through the following technical solution:

[0005] A push-button switching structure includes a body with a water inlet channel. The body further includes: a first water distribution chamber, to which water from the water inlet channel flows; a first water outlet and a second water outlet are located in the first water distribution chamber; the first water outlet is connected to a first water outlet channel on the body, and the second water outlet is connected to a second water outlet channel on the body; a movable central plug assembly is located within the first water distribution chamber, and movement of the central plug assembly allows water to flow from either the first or second water outlet; a second water distribution chamber... The water flow from the second outlet can flow into the second water distribution chamber. The second water distribution chamber is equipped with a third outlet and a fourth outlet. The second outlet can be connected to the third outlet configured on the main body, and the fourth outlet can be connected to the fourth outlet configured on the main body. A movable central plug assembly is also configured in the second water distribution chamber. The movement of the central plug assembly can enable water to be discharged from the third outlet or the fourth outlet. It also includes a pusher, which is configured to move linearly relative to the main body. The movement of the pusher can control the movement of the two central plug assemblies.

[0006] In this embodiment of the present invention, the first water distribution chamber and the second water distribution chamber are arranged on both sides of the main body; the first water distribution chamber is provided with a first water inlet that can connect the first water distribution chamber and the water inlet channel, and the first water outlet and the second water outlet are arranged on both sides of the first water inlet; the second water distribution chamber is provided with a second water inlet that can connect the second water distribution chamber and the second water outlet channel, and the third water outlet and the fourth water outlet are arranged on both sides of the second water inlet.

[0007] In this embodiment of the present invention, the central plug assembly includes a movable central plug, and a sealing ring is fitted on the central plug. The sealing ring can be moved to the sides of the first water inlet and the second water inlet.

[0008] In this embodiment of the present invention, the central plug assembly further includes a bushing that can be disposed within the first water distribution chamber and the second water distribution chamber. The central plug can move within the bushing. A water passage adapted to the first water outlet and the fourth water outlet is disposed on the side wall of the bushing. Sealing gaskets are disposed on the outer periphery of the bushing located on both sides of the water passage. A first sealing element adapted to the inner peripheral wall of the first water distribution chamber and the second water distribution chamber is disposed near the middle of the central plug. The first sealing element is located inside the second water outlet and the third water outlet. A second sealing element adapted to the inner peripheral wall of the bushing is disposed away from the middle of the central plug. The second sealing element is located outside the water passage.

[0009] In this embodiment of the utility model, slots are provided on both sides of the main body located at the first water distribution cavity and the second water distribution cavity. The outer periphery of the bushing is provided with a lug that can cooperate with the slot. The lug can be rotated to cooperate with the slot so that the bushing can be fixedly engaged with the main body.

[0010] In this embodiment of the present invention, the inner end of the central plug near the middle of the body can extend out of the first water outlet chamber and the second water outlet chamber. The inner end of the central plug can be placed in the middle of the body. The inner end of the central plug is provided with a guide groove. The pusher is provided with a guide rod. The guide rod is configured to be compatible with the guide groove so that the movement of the pusher drives the central plug to move.

[0011] In this embodiment of the invention, the pushing member is equipped with two guide rods, each guide rod cooperating with a guide groove on a central bolt; the guide rod includes a first straight section, a second straight section, and an inclined section, the inclined section being disposed between the first straight section and the second straight section, the first straight section and the second straight section being parallel to the moving direction of the pushing member, and the inclined section forming an angle with the moving direction of the pushing member; when the first straight section and the second straight section are engaged with the guide groove, the central bolt does not move, and when the inclined section is engaged with the guide groove, the movement of the pushing member can drive the central bolt to move within the first water outlet cavity and the second water outlet cavity.

[0012] In this embodiment of the present invention, the two first straight segments are located at both ends of the moving direction of the pusher, and the two second straight segments are located on both sides of the pusher; the two inclined segments can not cooperate with the guide groove at the same time, so that the two center bolts cannot move at the same time.

[0013] In this embodiment of the utility model, the guide groove is narrow in the middle and wide at both ends along the moving direction of the pusher, and guide slopes are formed on both sides between the middle and both ends of the guide groove; the length of the first straight section is less than the length of the second straight section.

[0014] This utility model also provides a water outlet component, including the aforementioned push-button switching structure, which enables switching between various water spray effects and is suitable for bathroom products such as shower heads and overhead sprayers. By integrating the push-button switching structure into the water outlet device, a diversified water outlet function integrated design is achieved.

[0015] This utility model discloses a push-button switching structure and water outlet component, which has the following advantages: First, the use of a linear motion pusher to achieve water flow switching simplifies the complexity of traditional ballpoint pen switching structures or toggle methods, reducing manufacturing costs and assembly difficulty. Second, users only need to push the push button to switch between different water outlet modes, requiring minimal effort and providing a better user experience. Third, by optimizing the design of the central plug assembly and the pusher component, multi-channel water flow switching is achieved, meeting the diverse needs of spray gun water output and integrating multiple functions into one product, thus improving its practicality. Finally, the design of sealing rings, sealing gaskets, and double sealing components ensures sealing during water flow switching, preventing leakage.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Referring to the accompanying drawings, the core technical solution of this utility model is a push-button switching structure, which mainly includes a body 1, a water inlet channel 2, a first water distribution chamber 3, a second water distribution chamber 4, two central plug assemblies 15, and a pusher 23. The body 1 serves as the basic structure of the entire device, internally designed with multiple water flow channels and cavities for water flow distribution and switching. The water inlet channel 2 is disposed on the body 1 and is used to introduce external water. The water flow from the water inlet channel 2 enters the first water distribution chamber 3 through the first inlet 5. The first water distribution chamber 3 has two outlets, namely the first outlet 7 and the second outlet 8. The first outlet 7 is connected to the first water outlet channel 11, and the second outlet 8 is connected to the second water outlet channel 12. In one embodiment, these structures are located on the upper side of the body, and the first water outlet channel can flow to the lower side of the body. A water outlet panel (not shown in the figure) can be disposed on the lower side of the body to form a water outlet component, specifically a shower head. This water outlet panel has various water spray patterns, which are switched by rotation. The water flow distribution within the first water distribution chamber 3 is controlled by the central plug assembly 15, which includes a central plug 16, a sealing ring 17, a bushing 18, a water outlet 19, a sealing gasket 20, a first seal 21, and a second seal 22. The central plug 16 can move linearly within the bushing 18 (left-right direction in the figure), thereby enabling selective opening of the first water outlet 7 or the second water outlet 8.

[0032] In the design of the first water distribution chamber 3, the first inlet 5 can be located in the middle of the first water distribution chamber, and the first outlet 7 and the second outlet 8 are located on both sides of the first inlet 5. The sealing ring 17 fitted on the central plug 16 can change position as the central plug 16 moves. When the sealing ring 17 moves to one side of the first outlet 7, the first outlet 7 is closed, and water can only flow out from the second outlet 8; conversely, when the sealing ring 17 moves to one side of the second outlet 8, the second outlet 8 is closed, and water can only flow out from the first outlet 7. This design ensures the accuracy and sealing of water flow switching. In addition, a water passage 19 is opened on the side wall of the bushing 18. The water passage 19 is adapted to the first outlet 7, and sealing gaskets 20 are provided on both sides of the water passage 19 to form a sealed connection between the bushing and the water distribution chamber, further enhancing the sealing effect during the water flow switching process. A first sealing element 21 is disposed at the end of the central plug 16 near the middle of the body 1. The first sealing element 21 is adapted to the inner peripheral wall of the first water distribution chamber 3 (second water distribution chamber) and is located inside the second water outlet 8 to prevent water leakage into other chambers. A second sealing element 22 is disposed at the end of the central plug 16 away from the middle of the body 1. The second sealing element 22 is adapted to the inner peripheral wall of the bushing 18 and is located outside the water outlet 19 to ensure that water can only flow out through the water outlet 19.

[0033] The design of the second water distribution chamber 4 is similar to that of the first water distribution chamber 3, but its function is slightly different. The second water distribution chamber 4 is connected to the second water outlet 12 via the second inlet 6. The second water distribution chamber 4 also has two outlets: a third outlet 9 and a fourth outlet 10. The third outlet 9 is connected to the third water outlet 13, and the fourth outlet 10 is connected to the fourth water outlet 14. The water flow distribution within the second water distribution chamber 4 is also controlled by the central auger assembly 15. The linear movement of the central auger 16 within the bushing 18 allows for the selective opening of either the third outlet 9 or the fourth outlet 10. The design of the second water distribution chamber 4 allows the water flow, after passing through the first water distribution chamber 3, to be further distributed to different outlet channels, meeting diverse water flow requirements.

[0034] In a preferred embodiment, three nozzles are provided on the upper side of the main body (with the water inlet at the bottom). The middle nozzle is connected to the third water outlet, and the other nozzles are connected to the fourth water outlet. This allows the main body to produce two types of water output. When applied to a shower head, the three nozzles 37 form two types of spray patterns. A pusher is used to switch between the two types of spray patterns and the water flow on the water outlet panel, giving the product more functional water features. The switching between functional water features is also simpler, and the overall structure is simple.

[0035] The pusher 23 is one of the key components of this utility model. It is configured to move linearly relative to the body 1. It may also have a push button 31 that pushes the pusher to move vertically relative to the body. Additionally, at least one limiting member 33 may be provided on the body to prevent the pusher from detaching from the body, or more specifically, to prevent the guide rod from detaching from the guide groove. The movement of the pusher 23 is controlled by the cooperation of the guide rod 24 and the guide groove 28 to control the movement of the center bolt assembly 15. The pusher 23 is equipped with two guide rods 24, each of which cooperates with the guide groove 28 on a center bolt 16. The two center bolts can be vertically offset on the body. The guide rod 24 includes a first straight section 25, a second straight section 26, and an inclined section 27. The first straight section 25 and the second straight section 26 are parallel to the moving direction A (vertical direction in the figure) of the pusher 23. When the first straight section 25 or the second straight section 26 of the guide rod 24 engages with the guide groove 28, the center bolt 16 remains stationary and moves axially within the water distribution chamber. When the inclined section 27 of the guide rod 24 engages with the guide groove 28, the movement of the pusher 23 causes the center bolt 16 to move linearly within the first water distribution chamber 3 or the second water distribution chamber 4. This design ensures that the movement of the center bolt 16 is precisely controlled while keeping the overall structure as small as possible, avoiding the simultaneous movement of two center bolts and preventing water leakage.

[0036] The main body 1 at the first water distribution chamber 3 and the second water distribution chamber 4 has slots 29 on both sides. The bushing 18 has lugs 30 on its outer periphery. The lugs 30 rotate and engage with the slots 29, thus fixing the bushing 18 inside the main body 1. This fixing method not only facilitates assembly but also enhances structural stability. The center plug 16 extends from the first water distribution chamber 3 and the second water distribution chamber 4 near the middle of the main body 1. The inner end of the center plug 16 is located in the middle of the main body 1 and is equipped with a guide groove 28. The guide groove 28 is narrow in the middle and wide at both ends along the moving direction of the pusher 23. Guide slopes 33 are formed on both sides between the middle and both ends of the guide groove 28, facilitating the engagement of the guide rod 24 with the guide groove 28, allowing the guide rod to drive one end of the center plug. The length of the first straight section 25 is less than the length of the second straight section 26 to ensure precise control of the movement of the center plug 16, thus adapting to the limitation that the two inclined sections cannot simultaneously drive the center plug, achieving precise switching of water flow.

[0037] At the same time, a groove (marked in the figure) can be set on the side of the pusher, and a ball 34 and a spring 35 can be set in the groove. A gear slot 36 is set on the main body. Each time a switch is completed, the ball can be inserted into the gear slot, and the sound produced can inform the user that the switch is completed. The two center plugs realize the combination switching of three water flows, so three gear slots can be set.

[0038] The working principle of this utility model is as follows: When the user pushes the pusher 23 (specifically, a push button), the linear movement of the pusher 23 will cause the guide rod 24 to engage with the guide groove 28. When the inclined section 27 of the guide rod 24 engages with the guide groove 28, the movement of the pusher 23 will drive the center bolt 16 to move linearly within the first water distribution chamber 3 or the second water distribution chamber 4. The movement of the center bolt 16 changes the position of the sealing ring 17, thereby achieving selective opening of the first water outlet 7 or the second water outlet 8. At the same time, after the water flows through the first water distribution chamber 3, it enters the second water distribution chamber 4, and the movement of the center bolt 16 within the second water distribution chamber 4 can achieve selective opening of the third water outlet 9 or the fourth water outlet 10. This design allows the water flow to different water outlet channels according to the user's needs, thereby achieving switching between various water splash effects.

[0039] The main application scenarios of this utility model are concentrated in the field of bathroom equipment, such as shower heads and overhead showers. By integrating a push-button switching structure into the water outlet device, a diversified water outlet function integrated design is achieved. For example, in shower products, users can switch between different water spray effects, such as rain mode, massage mode, and mist mode, by pushing the push button. In overhead shower products, users can switch between concentrated and dispersed water flow through the push-button switching structure to meet different usage needs. In addition, this utility model can also be applied to shower products with spray gun functions, realizing diversified functions of spray gun water through multi-channel water flow switching, forming multiple water flow patterns at the top of the shower head, no longer limited to one type of spray gun water, and can also add broom water or other water sprays, making the shower product not only integrate the function of showering, but also has multiple spray gun water spray rotations.

[0040] The technical advantages of this utility model are as follows: First, the use of a linear motion pusher 23 to switch water flow simplifies the complexity of traditional ballpoint pen switching structures or toggle mechanisms, reducing manufacturing costs and assembly difficulty. Second, users only need to push the push button to switch between different water output modes, requiring minimal effort and providing a better user experience. Third, by optimizing the design of the central plug assembly 15 and the pusher 23, multi-channel water flow switching is achieved, meeting the diverse needs of the spray gun's water output and integrating multiple functions into one product, thus improving its practicality. Finally, the design of the sealing ring 17, sealing gasket 20, and double sealing components ensures sealing during water flow switching, preventing leakage.

[0041] In summary, this utility model provides a push-button switching structure and water outlet component by optimizing the structural design and operating logic, which solves the problems of complex structure, inconvenient operation and single function in the prior art, and has significant technological progress and market application value.
