[0021] In the sixth technical solution and related embodiments, the positioning opening and the positioning protrusion cooperate to prevent axial displacement of the flow regulating base, improve the reliability of the flow regulating base transmission, and ensure the accurate transmission of the knob flow regulating action.

[0022] In the seventh technical solution and related embodiments, the transmission protrusion cooperates with the keyway to transmit the rotational motion to the flow regulating valve core, thereby realizing flow control.

[0023] In the eighth technical solution and related embodiments, the cooperation between the undercut and the limiting groove ensures the rotational freedom of the flow control knob while achieving axial limiting.

[0025] In the tenth technical solution and related embodiments, since the distance between the water outlet body embedded in the wall and the wall surface is uncertain, the axial height of the cover relative to the water outlet body is adjustable by sliding the drive rib on the knob with the guide groove of the flow adjustment base. Then, the cover and the water outlet body are fixedly connected to achieve the axial height adjustment of the cover relative to the water outlet body, which can adapt to the needs of different installation depths and improve the versatility and flexibility of the product.

[0044] See Figures 1 to 10 ,like Figure 1 As shown, a push-button valve includes a valve core assembly, a switch assembly, a resilient locking mechanism, and a flow regulating assembly.

[0045] Valve core assembly, such as Figure 5 As shown, it includes a press valve core 1 and a flow regulating valve core 2 arranged coaxially.

[0046] The push-button valve core 1 has a columnar structure extending axially, suitable for push-button operation to trigger a flow switch. One end of the push-button valve core 1 has a pressure head 11 for triggering the switch. The top of the pressure head 11 has a threaded hole 12 for connecting to an elastic locking mechanism. Around the threaded hole 12, the pressure head 11 has a radially protruding step 13. In this embodiment, the step 13 is a square step 13. The lower part of the pressure head 11 is coaxial with and rotatably connected to the flow regulating valve core 2.

[0047] The flow regulating valve core 2 is a sleeve-shaped structure surrounding the push-button valve core 1, suitable for rotational operation to regulate water flow. Specifically, the flow regulating valve core 2 has an axially arranged upper outer wall and a lower outer wall. The upper outer wall has symmetrically distributed keyways 22, which correspond to the flow regulating component. When the flow regulating component rotates, it can drive the flow regulating valve core 2 to rotate together. The lower outer wall has symmetrically distributed positioning protrusions 21, which cooperate with the flow regulating component to limit the axial displacement of the flow regulating component.

[0048] Switching components, such as Figures 1 to 3 As shown, it includes button 3 and pressing base 4.

[0049] Button 3 is fitted onto the pressing base 4, and the two are connected by a thread to achieve stepless adjustment of the axial height of button 3. Specifically, the inner wall of button 3 has an internal thread 31, which matches the first external thread 42 of the pressing base 4 to achieve a threaded connection. Button 3 consists of a threadedly connected pressure cap 32 and an adjusting ring 33. The pressure cap 32 covers the adjusting ring 33 and can be pressed. The adjusting ring 33 is cylindrical, and its inner wall has an internal thread 31, which is threaded to the pressing base 4. The upper circumference of the outer wall of the adjusting ring 33 has several axially extending limiting protrusions 34, which are inserted into and limited by the pressure cap 32.

[0050] Press the base 4, as shown Figure 6 and Figure 7As shown, it is sleeved on the press valve core 1 and connected to the press valve core 1 to prevent rotation. The outer wall of the press base 4 is provided with a first external thread 42 that mates with the internal thread 31 of the adjusting ring 33, realizing a threaded connection so that the axial height of the button 3 can be infinitely adjusted. The press base 4 is designed as a sleeve-shaped structure coaxial with the press valve core 1, and is divided into an upper open groove 44 and a lower open groove 45. The two open grooves are connected by a through hole 43 at their center. The through hole 43 corresponds to the position of the threaded hole 12 of the press valve core 1 so that the locking member 6 can pass through the through hole 43 and screw into the threaded hole 12. Figure 7 As shown, the lower opening groove 45 is adapted to the pressing valve core 1, and a recessed square groove 46 corresponding to the square step 13 of the pressing valve core 1 is provided around the through hole 43 at the bottom of the groove. This design enables the pressing base 4 and the pressing valve core 1 to achieve an anti-rotation connection. Figure 6 As shown, the outer wall of the pressing base 4 is also provided with two through holes 41 that cooperate with the elastic locking mechanism. These two through holes 41 are located on the outer wall of the upper opening groove 44 and are used to lock the axial position of the button 3 to realize the stepless adjustment of the height of the switch assembly.

[0051] The resilient locking mechanism includes a spring-loaded latch 5 and a locking element 6.

[0052] Snap 5, such as Figure 3 As shown, the spring clip 5 is an elastic element with a radially expandable locking portion 51, and a wedge-shaped protrusion 52 at the end of the locking portion 51. The spring clip 5 achieves radial expansion and contraction of the locking portion 51 through elastic deformation. The spring clip 5 is suitable for installation in the upper opening slot 44 of the pressing base 4, and the position of the wedge-shaped protrusion 52 corresponds to the two through holes 41.

[0053] The locking element 6 passes through the spring buckle 5 and is fixedly connected to the pressing valve core 1. Its function is to drive the locking part 51 to expand radially, thereby locking the axial position of the pressing base 4. In specific operation, the locking element 6 passes through the through hole 43 of the spring buckle 5 and the pressing base 4, and is connected to the threaded hole 12 at the top of the pressing valve core 1. By tightening the locking element 6, the locking part 51 of the spring buckle 5 expands radially, and the wedge-shaped protrusion 52 is embedded in the through hole 41 of the inner wall of the pressing base 4 and abuts against the button 3, thereby fixing the axial position of the button 3 after height adjustment. In this embodiment, the locking element is a screw.

[0054] Flow control components, such as Figures 1 to 3 As shown, it surrounds the switching assembly and is connected to the flow regulating valve core 2 for anti-rotation. The flow regulating assembly includes a knob 7, a flow regulating base 8, and a cover 9. They are installed together to achieve stepless adjustment of the switching assembly.

[0055] Knob 7 features a hollow structure design, such as Figure 8As shown, the flow control valve core 2 can be rotated by the user to adjust the water flow rate. The knob 7 is fitted onto the flow control base 8 and maintains a non-rotating connection with it. Simultaneously, the knob 7 and the flow control base 8 employ an axial sliding fit, allowing for stepless adjustment of the axial height of the knob 7. The knob 7 passes through the cover 9, allowing it to rotate freely relative to the cover 9 while being axially limited by it. An annular limiting groove 72 is provided in the middle of the outer wall of the knob 7, cooperating with the cover 9 to achieve rotational engagement and axial limitation. The upper part of the knob 7 is a rotating part 76, protruding above the cover 9. Several protrusions are arranged on the outer wall of the rotating part 76 to facilitate rotational operation. The lower outer wall of the knob 7 has radially protruding and circumferentially extending abutment ribs 73, which cooperate with the cover 9 to limit the rotation angle of the knob 7. A pair of drive ribs 71 are symmetrically provided on the lower part of the inner wall of the knob 7. They cooperate with the flow regulating base 8 to realize stepless adjustment of the axial position of the knob 7 and drive the flow regulating base 8 to rotate synchronously when the knob 7 is rotated.

[0056] The flow regulating base 8 adopts a sleeve-shaped structure, such as Figure 9 As shown, the flow control base 8 is fitted onto the outside of the flow control valve core 2 and maintains a non-rotating connection with it. The side wall of the flow control base 8 has two axially extending and symmetrically distributed guide grooves 81, which cooperate with the drive ribs 71 of the knob 7. The inner wall of the flow control base 8, located between the two guide grooves 81, has an inwardly radially protruding transmission protrusion 83, which cooperates with the keyway 22 of the flow control valve core 2, thereby driving the flow control valve core 2 to rotate. The outer wall of the flow control base 8 has two symmetrically arranged positioning openings 82 that match the positioning protrusions 21 of the flow control valve core 2, used to limit the axial displacement of the flow control base 8.

[0057] The faceplate 9 adopts a cap-like structure design, such as Figure 1 , Figure 2 and Figure 10 As shown, it has an opening for the flow control assembly to pass through. (As...) Figure 1 and Figure 2 As shown, several axially extending inverted buckles 91 are arranged along the inner periphery of the opening, which cooperate with the limiting groove 72 of the knob 7, so that the knob 7 can rotate freely relative to the cover 9, while being axially limited, thereby ensuring the rotational freedom of the flow control knob 7 while achieving axial position stability.

[0058] like Figure 10As shown, the inner side of the opening of the cover 9 is provided with a first limiting surface 93 and a second limiting surface 94 that extend axially and are circumferentially opposite to each other. The knob 7 is configured to rotate axially relative to the cover 9 between these two limiting surfaces. Specifically, the inner side of the opening is provided with an axially extending limiting block 92, whose two sides serve as the first limiting surface 93 and the second limiting surface 94, respectively. The two sides of the abutting rib 73 of the knob 7 are the first abutting surface 74 and the second abutting surface 75. When the knob 7 rotates clockwise relative to the cover 9, the first abutting surface 74 abuts against the first limiting surface 93, thereby limiting the clockwise rotation angle of the knob 7; when the knob 7 rotates counterclockwise relative to the cover 9, the second abutting surface 75 abuts against the second limiting surface 94, thereby limiting the counterclockwise rotation angle of the knob 7.

[0059] In this embodiment, the knob 7 is configured to rotate axially relative to the cover 9 between the first limiting surface 93 and the second limiting surface 94, thereby limiting the rotation angle of the knob 7 and preventing the valve body from being unable to withstand excessive knob force, thus improving the safety and reliability of the product.

[0060] In this embodiment, by integrating the push-button valve core 1 and the flow regulating valve core 2, the push-button knob valve combines on / off control and flow regulation functions to meet diverse usage needs. Addressing the installation adaptation challenges caused by variations in wall depth for concealed water outlet devices, this solution employs a threaded fit design between the button 3 and the push-button base 4, enabling stepless adjustment of the button 3's axial height. This ensures the product can flexibly adapt to installation environments of varying depths. During adjustment, the user can freely adjust the height of the button 3 according to actual installation requirements. Subsequently, the locking element 6 in the elastic locking mechanism drives the locking part 51 of the spring buckle 5 to expand radially, locking the axial position of the button 3. This effectively solves the problem of inconvenient operation or installation difficulties caused by mismatched installation depths, improving the product's installation adaptability and ease of use.

[0061] A concealed water outlet device, such as Figure 1 As shown, it includes a water outlet body 100 and the aforementioned push-button valve. Figure 2 As shown, the water outlet body 100 is pre-fixed to the wall using screws 101. After the cover 9 is engaged with the knob 7, the drive rib 71 on the knob 7 slides into the guide groove 81 of the flow adjustment base 8, allowing the axial height of the cover 9 relative to the water outlet body 100 to be adjustable. After adjustment, the cover 9 and the water outlet body 100 are fixedly connected using nuts 95.

[0062] The main water outlet 100 is equipped with a valve chamber, in which a push-button valve is installed. Since the distance between the main water outlet, embedded in the wall, and the wall surface is uncertain, the axial height of the cover 9 relative to the main water outlet 100 is adjustable by sliding the drive rib 71 on the knob 7 with the guide groove 81 of the flow adjustment base 8. Then, the cover 9 is fixedly connected to the main water outlet 100, achieving adjustable axial height of the cover 9 relative to the main water outlet 100 to accommodate different installation depths. This design improves the product's versatility and flexibility, solving the installation difficulties caused by the uncertainty of the wall depth in concealed water outlet devices.

[0063] In the specific installation process, the pressing base 4 is first fitted onto the pressing valve core 1, and its axial position is initially locked by the elastic locking mechanism. Then, the button 3 is fitted onto the pressing base 4, and by rotating the button 3, the internal thread 31 of its inner wall engages with the first external thread 42 of the pressing base 4, realizing stepless adjustment of the axial height of the button 3. When the button 3 is adjusted to a suitable height, the locking part 51 of the spring buckle 5 is driven to expand radially by tightening the locking part 6, so that the wedge-shaped protrusion 52 is embedded into the through-hole 41 of the pressing base 4 and abuts against the button 3, thereby fixing the axial position of the button 3 and adapting to the installation requirements of different wall depths.

[0064] Assemble the flow regulating component with the flow regulating valve core 2. The positioning opening 82 of the flow regulating valve core 2 and the positioning protrusion 21 of the flow regulating base 8 cooperate to limit the axial displacement of the flow regulating base 8. The drive rib 71 of the knob 7 slides with the guide groove 81 of the flow regulating base 8 to achieve height adjustment of the knob 7 relative to the flow regulating base 8. The buckle 91 on the base of the cover 9 cooperates with the limiting groove 72 of the knob 7, allowing the knob 7 to rotate relative to the cover 9 and be axially limited. After the cover 9 and the knob 7 are engaged, the drive rib 71 on the knob 7 slides with the guide groove 81 of the flow regulating base 8 to make the axial height of the cover 9 adjustable relative to the water outlet body 100. After adjustment, fix the cover 9 to the water outlet body 100 to make the axial height of the cover 9 adjustable relative to the water outlet body 100.

[0065] Pressing button 3 activates the pressing base 4, which in turn transmits power to the pressing valve core 1, triggering the water flow switch. The user rotates knob 7, whose driving rib 71 drives the flow regulating base 8 to rotate. The rotation of the flow regulating base 8 is transmitted to the flow regulating valve core 2 via the engagement of the transmission protrusion 83 and the keyway 22, thus regulating the flow rate. When knob 7 rotates clockwise or counterclockwise relative to the cover 9, the two sides of the abutting rib 73 abut against the first limiting surface 93 and the second limiting surface 94, respectively, limiting the rotation angle of knob 7.

[0066] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
