[0002] The pull-out shower heads currently on the market are also called pull-out heads, which are widely used on faucets in kitchens and bathrooms, making it convenient for users to obtain operable centralized or decentralized water output in different usage scenarios.

[0003] For example, Chinese patent application number 202420710913.1 discloses a water outlet switching structure of a pull-out head and a pull-out faucet, and Chinese patent application number 202220204113.3 discloses a multifunctional rotary switching pull-out head, both of which are dual-function water outlet operation modes, and switching between water channels is achieved by rotating or pulling.

[0004] However, existing dual-function pull-out heads typically utilize internal water channels and a central plug to achieve different water flow functions. This operation method is complex and inconvenient. In particular, the spray angles for each function are fixed, preventing users from adjusting the water flow angle as needed, limiting flexibility and user experience. Summary of the Invention

[0008] As a further improvement, the peripheral flexible panel is provided with a plurality of water outlet holes opened horizontally along the axis. After elastic deformation, the peripheral flexible panel is relatively squeezed and bulged outward, so that the water outlet holes are pulled and deformed to discharge water obliquely outward.

[0009] As a further improvement, the central water outlet column triggers the sealing shaft to switch position through the end cover, so that the sealing shaft directly drives the central water outlet column to move forward and backward relative to each other; and the central water outlet column is correspondingly provided with a water outlet nozzle that can form horizontal columnar water.

[0010] As a further improvement, a guide portion is provided at one end of the sealing shaft, and a resistance portion is correspondingly provided at the end of the central water outlet column; the sealing shaft and the central water outlet column are arranged vertically, and the resistance portion is slidably inserted into the guide portion, thereby converting the forward thrust of the guide portion into power for the resistance portion to move up and down.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Example

[0032] Combine Figures 1 to 10 This embodiment provides a pull-out head with adjustable water outlet angle, including a shell body 1, a water channel body 2, a switching mechanism, a water distribution mechanism and a water outlet mechanism.

[0033] The switching mechanism includes a sealing shaft 3 that is movably inserted into the water channel body 2, and an end cap 4 that cooperates with the sealing shaft 3. The end cap 4 is guided and arranged on one side of the housing body 1 to trigger the sealing shaft 3 to freely switch between the initial position and the pressed position relative to the water channel body 2.

[0034] The water diversion mechanism includes a water diversion body 5 sealedly connected to the water channel body 2. The water diversion body 5 is provided with a first water outlet 6 and a second water outlet 7. The water channel body 2 is correspondingly provided with a water inlet 8. When the sealing shaft 3 is in the initial position, the water inlet 8 is connected to the first water outlet 6. When the sealing shaft 3 is switched to the pressing position, the water inlet 8 is switched to connect to the second water outlet 7.

[0035] The water outlet mechanism has a central water outlet column 9 and a peripheral flexible panel 10. The central water outlet column 9 is movably arranged at the water outlet end of the water diversion body 5 toward the user side. The central water outlet column 9 is connected to the first water outlet 6. The peripheral flexible panel 10 is sealed and fixed between the central water outlet column 9 and the water outlet end. The peripheral water outlet panel is connected to the second water outlet 7.

[0036] Among them, when the end cover 4 is pressed to trigger the sealing shaft 3 to switch freely to the pressing position, it also drives the central water outlet column 9 to move forward and backward relative to the user side, so that when the peripheral flexible panel 10 is used to discharge water, it undergoes elastic deformation and thus adjusts the water outlet angle of its water outlet 11.

[0037] The above-mentioned pull-out head with adjustable water outlet angle triggers the sealing shaft 3 to switch between the initial position and the pressing position by pressing the end cover 4, and drives the central water outlet column 9 to move back and forth. No additional knobs or long-stroke levers are required, which is ergonomic and more intuitive and labor-saving to operate. In the dispersed water outlet mode, the movement of the central water outlet column 9 applies elastic deformation to the peripheral flexible panel 10, thereby adjusting the opening and scattering angle of the water outlet 11 according to the pressing force or the number of continuous pressing times, realizing stepless adjustment from light spray to large-angle wide-area water sprinkling, meeting the needs of different water outlet uses.

[0038] Furthermore, angle adjustment is achieved through the water distribution mechanism and the switching mechanism, without the need for additional adjustment components, keeping the overall lines of the pull-out head smooth, easy to clean and maintain, and improving the overall appearance and reliability of the product. Angle adjustment is achieved through the elastic properties of the flexible panel body. Compared with the traditional solution of adding mechanical adjustment devices, the number of parts and mold complexity are greatly reduced, and production costs are reduced. It can not only meet various cleaning needs in the kitchen, but can also be used in bathroom shower scenes, improving user experience and product applicability.

[0039] In this embodiment, the peripheral flexible panel 10 is provided with a plurality of water outlet holes 11 opened horizontally along the axis. After elastic deformation, the peripheral flexible panel 10 is relatively squeezed and bulged outward, so that the water outlet holes 11 are pulled and deformed to discharge water obliquely outward. On the one hand, the water outlet holes 11 on the peripheral flexible panel 10 are pulled into oblique water outlets after elastic deformation, and the water flows outward obliquely. Compared with traditional horizontal spray holes, a wider water mist fan can be formed, which significantly increases the coverage area and meets the one-time flushing needs of large items or large surfaces. On the other hand, as the pressing force changes, the protruding curvature of the flexible panel and the inclination angle of the water outlet hole 11 can be adjusted steplessly, so that the opening of the water outlet fan surface transitions from small to large, ensuring a smooth switch from clustering to diffusion, and reducing splashing and discomfort caused by sudden changes in the impact force of the water flow.

[0040] Preferably, the peripheral flexible panel 10 is a silicone sleeve made of an aging-resistant, highly elastic polymer to ensure long-term stable use. It is important to note that the silicone sleeve maintains excellent elastic recovery properties even after repeated extrusion and deformation, preventing cracking, hardening, or permanent deformation, thereby ensuring product stability and reliability during multiple switching and continuous use.

[0041] In this embodiment, the central water column 9 triggers the sealing shaft 3 to switch positions through the end cover 4, so that the sealing shaft 3 directly drives the central water column 9 to move forward and backward relative to each other. Only by relying on the end cover 4 to trigger the switching of the sealing shaft 3 between the initial position and the pressing position, the central water column 9 can be directly driven to move forward and backward, which greatly simplifies the internal structure, reduces the number of parts, and improves reliability. In addition, by utilizing the rigid fit between the sealing shaft 3 and the central water column 9, the central water column 9 is quickly reset when switched to the initial position, and a horizontal columnar water flow is realized corresponding to the first water outlet 6. When switched to the pressing position, the central water column 9 moves forward, and cooperates with the peripheral flexible panel 10 to complete the dispersed mode. The switching process is smooth and the positioning is precise, which meets the needs of rapid switching between different modes.

[0042] Furthermore, the central water column 9 is provided with a corresponding nozzle for forming a horizontal column of water. Obviously, a dedicated nozzle is provided at the top of the central water column 9. In the initial position, the water inlet 8 of the water channel body 2 is directly connected to the first water outlet 6. A stable horizontal columnar jet is formed through the central water column 9, which has the characteristics of concentrated water column and strong impact force, suitable for removing stubborn stains and precisely rinsing the edges of components.

[0043] Specifically, a guide portion 12 is provided at one end of the sealing shaft 3, and a resistance portion 13 is correspondingly provided at the end of the central water outlet column 9. The sealing shaft 3 and the central water outlet column 9 are arranged vertically, and the resistance portion 13 is slidably inserted into the guide portion 12, so as to convert the forward thrust of the guide portion 12 into the power for the resistance portion 13 to move up and down. Thus, the horizontal thrust of the sealing shaft 3 is directly converted into the vertical movement of the central water outlet column 9 by means of the sliding fit between the guide portion 12 and the resistance portion 13, without the need for additional connecting rods or gear transmissions, which significantly improves the force transmission efficiency and response speed. In addition, the sealing shaft 3 is arranged vertically with the central water outlet column 9, and the guide portion 12 and the resistance portion 13 are slidably inserted into an integrated design, which reduces the number of parts and assembly links, reduces the internal space occupied, and reduces the manufacturing and maintenance costs.

[0044] Furthermore, the guide portion 12 includes a forward guide slope and a backward guide slope, wherein the forward guide slope is used to push the resistance portion 13 upward so that the central water column 9 moves relatively backward toward the user side, and the backward guide slope is used to press the resistance portion 13 downward so that the central water column 9 moves relatively forward toward the user side. In this way, when the sealing shaft 3 is pushed forward, the forward guide slope decomposes the horizontal thrust upward along the inclined surface, accurately lifts the resistance portion 13 and drives the central water column 9 to move backward. When the sealing shaft 3 is reset, pulled back or lightly pressed, the backward guide slope decomposes the pushing force downward, accurately presses the resistance portion 13 to move the central water column 9 forward, and thus the double slopes make the thrust conversion more efficient and controllable.

[0045] The end cap 4 is provided with a corresponding push portion 14 for driving the guide portion 12 to move, and the end cap 4 and the housing body 1 are slidably fitted with a guide rail, and an anti-separation structure is provided between them. In this embodiment, a guide post 15 is provided on the inner side of the end cap 4, and a guide groove 16 is provided on the inner side wall of the housing body 1, which is plugged and slidably engaged with the guide post 15, thereby guiding the end cap 4 to be quickly pressed and reset on one end of the housing body 1. Preferably, the anti-separation structure is an elastic hook 17 provided at the end of the guide post 15. In order to prevent the guide post 15 from being separated from the guide groove 16 of the housing body 1 after the end cap 4 is reset, the elastic hook 17 is hooked and limited to the guide groove 16.

[0046] A return spring 18 is provided at one end of the sealing shaft 3, abutting between the sealing shaft 3 and the housing body 1 to maintain the sealing shaft 3 in its initial position. Once the pressure from the end cap 4 is released, the sealing shaft 3 quickly and reliably rebounds to its initial position, ensuring that each water flow mode starts from the predetermined horizontal columnar state after each shift, and facilitating automatic reset after subsequent gear adjustments.

[0047] In this embodiment, the water channel body 2 is provided with a connector 19 at the end of the water inlet 8. The connector 19 is threadedly mounted at the water inlet end of the water channel body 2. It should be noted that the standard threaded connector 19 provided at the end of the water inlet 8 of the water channel body 2 can be quickly connected to various hoses or water inlet pipes through threads without the need for additional sealing gaskets or special tools, significantly simplifying the installation process and improving the system's universal adaptability. In addition, the connector 19 and the water channel body 2 are threadedly fastened and can be used with O-rings or washers to further enhance the sealing performance, effectively resisting the risk of leakage in high water pressure environments and ensuring the long-term stable operation of the water channel.

[0048] like Figure 5 、 Figure 8 、 Figure 9 and Figure 10 As shown, in this embodiment, the pull-out head further includes a shifting member 20. A shifting groove 21 is provided on one side of the waterway body 2, correspondingly cooperating with the shifting member 20. By guiding the relative position of the shifting member 20 within the shifting groove 21, two corresponding positions of the sealing shaft 3 are defined. The shifting groove 21 is constructed as an irregular, arcuate, annular hook groove. A single press on the end cover 4 shifts the shifting member 20 from the first position to the second position. A subsequent press shifts the shifting member 20 from the second position back to the first position.

[0049] In the above, by pressing the end cover 4 once, the sealing shaft 3 is switched to the pressing position accordingly. At this time, the central water column 9 moves forward, thereby triggering the peripheral flexible panel 10 to be squeezed and deformed. At this time, water is dispersed along the water outlet 11 for the user to use. By pressing the end cover 4 again, the sealing shaft 3 continues to move, driving the central water column 9 to continue to move forward and increase the elastic deformation. Correspondingly, the water outlet angle of the water outlet 11 is expanded outward by a certain amplitude again. When the pressing is released, the shifting member 20 switches from the second gear back to the first gear. At this time, the sealing shaft 3 is reset to the initial position, and the central water column 9 moves backward, causing the peripheral flexible panel 10 to elastically return to its original state.

[0050] It should be understood that the gear switching method can also adopt other positioning or locking forms, and no excessive restrictions are made here.

[0051] In addition, this embodiment provides a water faucet, including the above-mentioned pull-out head with adjustable water outlet angle.

[0052] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
