[0039] 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. 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 utility model for protection, but merely represents the selected embodiments of the present invention. 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.

[0040] This embodiment allows shower-related functions to be performed by installing the shower head on the bathroom wall and connecting the pipes. The switch knob is set in the hidden switch compartment of the shower head and is connected to the push-to-flow regulating valve core. By pressing the knob, the switch knob can be popped out with the cooperation of the spring assembly, and the push-to-flow regulating valve core is activated in conjunction with it, so that the push-to-flow regulating valve core can control the on / off state of the shower water outlet. At the same time, the push-to-flow regulating valve core can be rotated and adjusted by rotating the switch knob to control the water output. After that, pressing the switch knob again will cause the spring assembly to contract and retract the switch knob into the shower head body, making it hidden. This further expands the application space of the valve core and greatly improves the practicality and convenience of the shower head. The specific implementation is as follows:

[0041] like Figures 1 to 13As shown, a hidden switch knob shower comprises a shower body 1, a switch knob 2, a spring assembly and a push-flow regulating valve core 13. A push-flow regulating valve core 13 is arranged inside the shower body 1, and the top adjustment end of the push-flow regulating valve core 13 is connected to a rotary adjustment assembly, which is arranged at one end of the spring assembly, and the other end of the spring assembly is connected to the switch knob 2. The spring assembly is arranged in a pressure cover 10, and the bottom of the pressure cover 10 is connected to the push-flow regulating valve core 13. A hidden switch compartment 14 is formed on the front of the shower body 1, and the switch knob 2 is installed in the hidden switch compartment 14 and can move along the length direction of the hidden switch compartment 14, and the switch knob 2 is connected to the push-flow regulating valve core 13 through the spring assembly and the rotary adjustment assembly. After the shower is installed on the bathroom wall and connected to the pipes, shower-related functions can be performed. The switch knob 2 is set in the hidden switch compartment 14 of the shower and is connected to the push-flow regulating valve core 13. By pressing the knob, the switch knob 2 can be popped out with the cooperation of the spring assembly, and the push-flow regulating valve core 13 is started in association, so that the push-flow regulating valve core 13 can control the switch state of the shower water outlet. At the same time, the push-flow regulating valve core 13 can be rotated and adjusted by rotating the switch knob 2 to control the water outlet. After that, the switch knob 2 is pressed again, the spring assembly contracts and the switch knob 2 is retracted into the inside of the shower body 1 and hidden, further expanding the application space of the valve core and greatly improving the practicality and convenience of the shower.

[0042] The push-to-flow control valve core 13 is a functional component. Pressing the middle rod on the valve core controls the waterway's opening and closing, while rotating the toothed part on the outside of the rod controls the flow rate. The showerhead can accommodate both push-to-flow control valve cores and push-to-temperature control valve cores. The on / off knob 2 is a functional exterior component and can be made of materials such as plastic, aluminum alloy, zinc alloy, and copper. The knob is pressed on the front surface, and when it pops out of the main body, it can be rotated to control the flow rate or temperature. For aesthetic reasons and ease of operation, it is typically cylindrical with a non-slip surface. The gland 10 is an internal component that secures the rear components of the slide 8 within the showerhead body 1, preventing the valve core from being pushed open by water pressure and causing leakage. It also ensures that the slide 8, eccentric seat 11, and eccentric ring 12 can rotate and adjust the flow rate of the valve core. This requires withstanding torsional forces and water pressure, and is typically made of plastics such as ABS, PC, and POM, or easily machined materials such as copper.

[0043] As a preferred embodiment, the spring assembly includes a retaining spring 5, a guide body 7, a slide 8, and a return spring 9. The retaining spring 5 is mounted on the inside of the guide body 7. The top of the guide body 7 is connected to the switch knob 2. The guide body 7 is sleeved on the outside of the slide 8, and the two sides of the slide 8 are movably connected to the ends of the retaining spring 5. Two spring guide posts 19 are symmetrically mounted on the slide 8. Two return springs 9 are respectively sleeved on the two spring guide posts 19. The two spring guide posts 19 and the two return springs 9 are all disposed in spring stop holes 18 of the guide body 7. Under the action of the spring assembly, the switch knob 2 can be pressed, causing the guide body 7 to drive the retaining spring 5 toward the inside of the knob. The retaining spring 5 deforms and slides under the guidance of the guide rails on the side walls of the slide 8. After a certain degree of pressure, it reaches the limit surface. Under the elastic force of the return spring 9 on the slide 8, the guide body 7 and the switch knob 2 are ejected. After the guide body 7 is ejected a certain distance, it is restrained by the limit rod 6. At this time, the switch knob 2 is ejected from the shower body 1 by the designed distance.

[0044] The retaining spring 5 is a built-in functional component. To ensure a longer service life, it is typically made of a resilient metal material, such as SUS304. Its function is to restrict the position of the guide body 7 in the closed state, preventing it from being spring-loaded. The spring 9 is a built-in functional component, providing the elastic force that allows the switch knob 2 to be ejected when needed. Considering the lifespan of the compression-release mechanism and the humidity of the environment, SUS304 metal is typically used. The slide 8 is a built-in functional component, primarily providing a locking point during closing, guiding the spring force, and constraining the components during rotation. Considering strength and motion characteristics, it is typically made of a plastic component with good strength, good wear resistance, and low friction resistance, such as POM, ABS, or PC.

[0045] As a preferred embodiment, first and second guide rails 21, 22 are formed on either side of the slide 8, respectively, and retaining spring grooves are formed in the middle of the first and second guide rails 21, 22. In the pop-up state, pressing the switch knob 2 again transmits the pressing force through the switch knob 2 to the guide body 7, which overcomes the elastic force of the return spring 9 and moves into the interior of the hidden switch compartment 14. During this process, the return spring 9 is compressed, and the retaining spring 5 is simultaneously drawn into the guide rails of the slide 8 and moves until the guide body 7 contacts the valve core. Further downward pressure causes the guide body 7 to push the valve core to switch to the closed state. After reaching the set limit, the switch knob 2 is released, and the spring pushes the guide body 7 and retaining spring 5 apart. The retaining spring 5 is then restrained in the retaining spring grooves set in the guide rails of the slide 8. The valve core now switches from the open state to the closed state, and the guide body 7 is also restrained within the shower body 1 by the retaining spring 5. Simultaneously, the switch knob 2 is also restrained within the shower body 1.

[0046] The spring guide column 19 provided on the slide 8 can guide the reset spring 9 to directional stretch and compression. At the same time, a spring limiting hole 18 is provided on the guide body 7 to limit the movement of the spring in the hole and not be interfered with by other external parts.

[0047] As a preferred embodiment, the guide body 7 is formed with several anti-rotation limit grooves 17 on its exterior, and the switch knob 2 is formed with several anti-rotation limit bosses 16 on its interior, which cooperate with the anti-rotation limit grooves 17. With the anti-rotation limit bosses 16 and anti-rotation limit grooves 17 cooperating, after assembly, rotating the switch knob 2 simultaneously drives the guide body 7 to rotate. Pressing the knob also pushes the guide body 7 inward, causing the guide body 7 to be repelled by a spring, which in turn causes the switch knob 2 to be repelled.

[0048] The guide body 7 is a built-in functional part, which mainly receives the switch knob 2 and the reset spring 9 and clamps the limit rod 6 after the knob pops out. It is usually made of plastic material.

[0049] As a preferred embodiment, the edge of the slide 8 is formed with a plurality of cylindrical sliding bosses 20. The sliding bosses 20 fit tightly with the bottom end of the pressure cover 10. The middle part of the pressure cover 10 forms a limit chamber 15. The limit rod 6 is movably installed in the limit chamber 15. The bottom end of the limit rod 6 is connected to the top of the pressure regulating valve core 13. By providing the sliding bosses 20 on the slide 8, the contact area with the pressure cover 10 can be reduced, thereby reducing the rotational friction. The limit rod 6 is a built-in functional component. One end is designed with a thread for easy connection with the valve stem of the valve core, and the other end is designed with a sliding hole larger than the guide body. In this way, it can hang on the guide body 7 and prevent it from being bounced off by the return spring 9. Its function is to control the pop-up stroke of the switch knob 2. The force borne by the limit rod 6 is mainly elastic force. It can be made of plastic or metal materials, such as ABS, PC, POM, etc., or copper, SUS304 stainless steel, etc., but corrosion-resistant materials are usually selected.

[0050] As a preferred embodiment, the rotation adjustment assembly includes an eccentric seat 11 and an eccentric ring 12. The eccentric seat 11 is sleeved on the outside of the eccentric ring 12. A plurality of clamping columns 23 are installed on the top of the eccentric seat 11, and a clamping position matching the clamping columns 23 is formed on the bottom of the slide 8. A plurality of clamping grooves 24 are provided on the inner side of the eccentric seat 11, and a plurality of external bosses 26 matching the clamping grooves 24 are formed at corresponding positions on the outer side of the eccentric ring 12. The clamping position provided inside the slide 8 can make the clamping columns of the eccentric seat 11 clamped on the clamping position. When the slide 8 rotates, the rotational force can be transmitted through the clamping columns 23, so that the eccentric seat 11 rotates synchronously.

[0051] The eccentric ring 12 and the eccentric ring 11 are internal functional parts, which are mainly used to control the rotation of the valve core and need to withstand torsional force. The materials used are usually plastic materials, such as ABS, PC, POM, etc., and easy-to-process materials such as copper.

[0052] As a preferred embodiment, a plurality of guide protrusions are provided on the outside of the eccentric ring 12, and a plurality of matching guide grooves 25 are formed at corresponding positions of the eccentric seat 11. When the outer boss 26 on the eccentric ring 12 is inserted into the slot 24 of the eccentric seat 11, the eccentric ring 12 is restricted in the guide groove 25 by the guide protrusions and can slide along the length direction of the guide groove 25.

[0053] As a preferred embodiment, an inner tooth groove 27 is formed on the inner wall of the eccentric ring 12, and an adjusting gear 28 that meshes with the inner tooth groove 27 is formed on the top of the pressure-controlled flow regulating valve core 13. The eccentric ring 12 and the adjusting gear 28 of the pressure-controlled flow regulating valve core 13 can be assembled first, and the clamping groove 24 of the eccentric seat 11 is then aligned with the outer boss 26 of the eccentric ring 12 and installed, so that the eccentric seat 11 and the eccentric ring 12 form a whole. At the same time, the slide 8 is clamped by the eccentric seat 11. When the slide 8 rotates, the eccentric seat 11 can be driven to rotate by the clamping column 23. The eccentric seat 11 can be connected to the eccentric ring 12 via the outer boss 26, and the eccentric ring 12 is connected to the valve core via the inner tooth groove 27, thereby driving the valve core to rotate and adjusting the valve core flow rate.

[0054] As a preferred embodiment, a cover bracket is provided on the top of the shower body 1, on which an upper cover plate 4 is mounted. A thermostat 3 is mounted on the front of the shower body 1, next to the switch knob 2. The thermostat 3 is responsible for adjusting the outlet water temperature. The upper cover plate 4, located at the topmost layer of the shower body 1, is primarily designed for assembly convenience. This allows for easy installation of the components into the housing. After installation, the cover plate is replaced to conceal the internal components and enhance the product's aesthetics. Due to its flat design, it offers ample storage space. Materials typically include plastics, such as PMMA and PC, for ease of injection molding and a certain degree of scratch resistance. Tempered glass may also be used for enhanced performance.

[0055] As a preferred embodiment, the switch knob 2 is made of aluminum alloy, and the shower body 1 is made of PPA plastic. The shower body 1 primarily consists of three components: the housing, the waterway valve body, and the cover. To minimize overall product cost, the housing is typically made of plastic materials such as ABS, copper, or SUS304 stainless steel. To ensure aesthetic color and corrosion resistance, materials that are easily surface-treated, such as chrome plating or powder coating, are typically selected. The waterway valve body supports the valve core and other components. The press-type flow regulating valve core 13 is mounted on the waterway valve body. The product's water flow and water flow path are both designed into the waterway valve body. The internal waterway valve body withstands not only high-pressure water but also the impact of prolonged cold and hot water flow. Therefore, the internal waterway valve body is typically made of a high-pressure, high-temperature resistant material, such as PPA plastic or copper. Because it is internal to the product, color is not a consideration, but water flow requires consideration of the absence of toxic substances dissolved in the water.

[0056] Working principle: After installing the shower head on the bathroom wall and connecting the pipes, you can perform shower-related functions. Set the switch knob in the hidden switch compartment of the shower head and press the flow regulating valve core. By pressing the knob, the switch knob can be popped out with the cooperation of the spring assembly, and the press flow regulating valve core is activated in conjunction, so that the press flow regulating valve core can control the on / off state of the shower water. At the same time, the press flow regulating valve core can be rotated and adjusted by rotating the switch knob to control the water output. Then press the switch knob again, the spring assembly contracts and retracts the switch knob to the shower head The valve core is located inside the main body of the shower and is hidden, which further expands the application space of the valve core and greatly improves the practicality and convenience of the shower. Under the action of the spring assembly, the switch knob can be pressed to make the guide body drive the retaining spring to move inside the knob. The retaining spring deforms and slides under the guidance of the guide rail on the side wall of the slide. After being pressed to a certain extent, it can reach the limit surface and under the elastic force of the reset spring on the slide, the guide body and the switch knob are popped out. After the guide body is popped out a certain distance, it is restricted by the limit rod. At this time, the switch knob pops out a designed distance from the shower body and is released. In the out state, press the switch knob again, the pressing force will be transmitted to the guide body through the switch knob, and the guide body will overcome the elastic force of the reset spring and move toward the inside of the hidden switch compartment. During this process, the reset spring is compressed, and the retaining spring is also synchronously brought to the guide rail of the slide to move until the guide body contacts the valve core. Press down again, and the guide body will push the pressing valve core to switch to the closed state. After reaching the set limit, release the switch knob. At this time, the spring will push the guide body and the retaining spring, and the retaining spring is confined to the retaining spring groove set in the slide guide rail. At this time, the valve core has also completed the switch from the open state to the closed state. When switching to the closed state, the guide body is also restricted by the retaining spring inside the main body, and the switch knob is also restricted inside the shower main body. The eccentric ring can be assembled with the adjusting gear of the flow regulating valve core first, and the slot of the eccentric seat is aligned with the boss of the eccentric ring and installed, so that the eccentric seat and the eccentric ring form a whole. At the same time, the slide is clamped by the eccentric seat. When the slide rotates, the eccentric seat can be driven to rotate by the clamping column. The eccentric seat can be connected to the eccentric ring through the boss, and the eccentric ring is connected to the valve core rod through the tooth groove, thereby driving the valve core to rotate and adjusting the valve core flow.
