[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] Example Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a wall-mounted concealed faucet 100, including a wall-mounted valve body assembly 110, an adjusting handwheel assembly 120, and a water outlet pipe assembly 130; please refer to Figure 4 and Figure 5 The wall-mounted valve body assembly 110 includes a valve body 101, a valve core 102, and a water outlet connector 105. The valve body 101 has a fixed connector 106 for mounting the water outlet connector 105. The end of the water outlet connector 105 away from the fixed connector 106 is connected to the water outlet pipe assembly 130. The valve core 102 is rotatably mounted within the valve body 101 to regulate the water temperature and / or flow rate. The valve core 102 has an extended toothed rod 103 for connection to the regulating handwheel assembly 120. The extended toothed rod 103 has external teeth 1031 on its outer wall and internal teeth 1032 at its end. The internal teeth 1032 engage with the valve core 102. (See also...) Figure 6 and Figure 7 The adjusting handwheel assembly 120 includes a handwheel 121 and a toothed mandrel 122. The toothed mandrel 122 is provided with an external tooth 1221 at its end and an internal tooth 1222 on its inner wall. The external tooth 1221 engages with the internal tooth of the handwheel 121. An extended toothed rod 103 passes through the toothed mandrel 122 and is connected by the engagement of the external tooth 1031 and the internal tooth 1222, allowing the extended toothed rod 103 to slide on the toothed mandrel 122, thereby adjusting the installation depth. Please refer to [link to relevant documentation]. Figure 12 One end of the water outlet connector 105 is threadedly connected to the fixed connector 106 to adjust the extension length of the water outlet connector 105.

[0026] In this invention, the extended toothed rod 103 on the valve core 102 and the toothed spindle rod 122 on the adjusting handwheel assembly 120 utilize the meshing of the outer teeth 1031 of the toothed rod and the inner teeth 1222 of the spindle rod to allow the extended toothed rod 103 to slide along the toothed spindle rod 122 in the installation direction, thereby facilitating the adjustment of the installation depth. Simultaneously, the extension length of the water outlet connector 105 is adjusted via the threaded connection between the water outlet connector 105 and the fixed connector 106. Through these adjustments, it is ensured that regardless of changes in the installation depth of the wall-embedded valve body assembly 110, the adjusting handwheel assembly 120 and the water outlet pipe assembly 130 maintain a uniform exposed appearance, preventing changes in the distance between the adjusting handwheel assembly 120 and the wall, and the distance between the water outlet pipe assembly 130 and the wall, as the wall-embedded valve body 101's depth changes, which would otherwise affect the product's aesthetics and actual performance.

[0027] Please refer to Figure 4The valve core 102 is also provided with valve core driving external teeth 1023 and valve core fixing internal teeth 1024. The inner wall of the extended toothed rod 103 is also provided with a limiting platform 1033 and a first fixing screw 1034. The extended toothed rod 103 is sleeved on the valve core 102 and meshes with the valve core driving external teeth 1023 through the toothed rod internal teeth 1032. The upper surface of the valve core driving external teeth 1023 contacts the lower surface of the limiting platform 1033 and is fixed by the first fixing screw 1034 in cooperation with the valve core fixing internal teeth 1024. The limiting platform 1033 ensures the proper installation position of the valve core 102 and the extended toothed rod 103, while the first fixing screw 1034 tightly connects the valve core 102 and the extended toothed rod 103 together. This allows the extended toothed rod 103 and the valve core 102 to transfer rotational force through the meshing of the inner teeth 1032 of the toothed rod and the outer teeth 1023 of the valve core drive. Axially, the positions of the valve core 102 and the extended toothed rod 103 are fixed and will not shift with rotation. When the handwheel 121 rotates, it drives the toothed mandrel 122 connected to it to rotate. The rotation of the toothed mandrel 122 drives the extended toothed rod 103, which in turn rotates. The rotation of the extended toothed rod 103 further drives the rotation of the valve core 102, allowing for the regulation of temperature and flow rate during rotation.

[0028] In some embodiments, an extension nut 104 is provided on the valve body 101, the valve core 102 is located inside the extension nut 104, and the adjusting handwheel assembly 120 also includes a bell jar 124 and a bell jar base 127 provided at the bottom of the bell jar 124. The toothed spindle 122 passes through the bell jar base 127 and the bell jar 124 in sequence and is connected to the handwheel 121. The toothed spindle 122 and the handwheel 121 are fixed by a second fixing screw 123. The bell jar base 127 is provided with an internal thread, and the extension nut 104 is threadedly connected to the internal thread of the bell jar base 127 to adjust the installation length of the extension nut 104. The extension nut 104 protects the valve core 102 and connects the valve body 101 and the adjusting handwheel assembly 120. The bell jar 124 has a trapezoidal hollow structure. The bell jar 124 provides a certain installation space for the installation and transmission between the valve core 102 and the handwheel 121, and also provides some space for changes in installation depth, which helps to ensure the final installation effect and the overall aesthetic appearance. Furthermore, the extension nut 104 in this invention is connected to the bell jar base 127 via a threaded connection, allowing adjustment of the length of the extension nut 104 extending into the bell jar 124. In this invention, the second fixing screw 123 is used to fix the toothed spindle 122 and the handwheel 121, ensuring that the handwheel 121 can drive the toothed spindle 122 to rotate when it rotates. A bell jar base sealing ring 128 is provided at the connection point between the bell jar base 127 and the wall.

[0029] The structure of the extension nut 104 includes a nut base 1041 and an extension rod 1042 connected to each other. The nut base 1041 and the extension rod 1042 are stepped. The nut base 1041 is threaded to the valve body 101, and the extension rod 1042 is provided with an extension external thread that is threaded to the internal thread of the bell base 127.

[0030] Please refer to the following: Figure 4 and Figure 6 Since the toothed mandrel 122 passes through the bell base 127 and the bell 124 in sequence and is connected to the handwheel 121, and the bell 124 and the bell base 127 are respectively provided with corresponding through holes, the handwheel 121 and the toothed mandrel 122 will not drive the bell 124 and the bell base 127 to rotate when they rotate. In order to avoid the influence of the rotation of the handwheel 121 and the toothed mandrel 122 on the bell 124, in this utility model, a friction ring 125 and a clamping nut 126 are also provided inside the bell 124. The friction ring 125 is stepped and matches the upper inner wall of the bell 124. The clamping nut 126 is connected to the internal thread of the inner wall of the bell 124 to clamp the toothed mandrel 122 so that it abuts against the friction ring 125. The friction ring 125 and the clamping nut 126 make the installation position of the toothed mandrel 122 inside the bell housing 124 relatively fixed. The toothed mandrel 122 can only rotate relative to the bell housing 124 and cannot slide up and down relative to it, thus ensuring the stability of the overall structure of the adjusting handwheel assembly 120.

[0031] In this application, the bell jar 124, the bell jar base 127, the friction ring 125 and the clamping nut 126 are a whole. When the bell jar base 127 is installed on the extension nut 104, the rotation of the bell jar base 127 will cause the bell jar 124, the friction ring 125 and the clamping nut 126 to rotate together.

[0032] The valve core 102 in this application includes a flow switch valve core 1021 and a temperature regulating valve core 1022. The regulating handwheel assembly 120 includes a flow regulating handwheel 1201 and a temperature regulating handwheel 1202. The flow regulating handwheel 1201 is connected to the flow switch valve core 1021, and the temperature regulating handwheel 1202 is connected to the temperature regulating valve core 1022. The flow regulating handwheel 1201 and the temperature regulating handwheel 1202 have essentially the same structure, both consistent with the structure of the regulating handwheel assembly 120 described above. This structural consistency reduces the development of product parts during production and enhances versatility.

[0033] Please see Figure 4Both ends of the water outlet connector 105 are equipped with water outlet sealing rings 1051 to ensure the water outlet is sealed and prevent leakage. The fixed connector 106 is threadedly connected to the valve body 101, and the fixed connector 106 is equipped with a connector sealing ring 1061 and an elastic retaining ring 1062. The elastic retaining ring 1062 can play a limiting role to prevent the water outlet connector 105 from coming out of the fixed connector 106.

[0034] Please see Figure 8 The water outlet pipe assembly 130 includes a water outlet pipe base 131 and a water outlet pipe 132. A water outlet connector 105 is inserted through the water outlet pipe base and into the water outlet pipe 132. The side of the water outlet pipe 132 is provided with a locking hole 133 and a locking screw 134. The locking screw 134 passes through the locking hole 133 and abuts against the water outlet connector 105. The water outlet pipe 132 and the water outlet pipe base 131 are connected by a locking screw 135. The locking screw 135 can stably connect the water outlet pipe 132 and the water outlet pipe base 131. The connection method between the water outlet pipe 132 and the water outlet connector 105 is simple. By using the "insertion + locking" method, the water outlet connector 105 can be stably fixed into the water outlet pipe 132.

[0035] The water outlet base 131 and water outlet pipe 132 can be pre-connected and fixed at the factory using locking screws 135. During installation, no further assembly is required. Simply align the inlet of the water outlet pipe assembly 130 with the water outlet connector 105 and insert it until the end face of the water outlet base 131 is flush with the wall. Then tighten the two locking screws 134 to complete the installation. A water outlet sealing ring 136 is provided at the point where the water outlet base 131 is flush with the wall to ensure a tight seal and prevent water leakage. The water outlet end of the water outlet pipe 132 is equipped with a water outlet nozzle 137, which improves the water flow effect of the water outlet pipe 132 and has functions such as splash prevention, filtration, and water flow regulation.

The upper surface of the valve core drive outer tooth 1023 contacts the lower surface of the limiting platform 1033 and is fixed by the first fixing screw 1034 and the valve core fixing inner tooth 1024. The extension nut 104 is threadedly connected to the valve body 101. One end of the water outlet connector 105 is threadedly connected to the fixing connector 106 to adjust the extension length of the water outlet connector 105.

[0037] (2) Assembly of the adjustment handwheel assembly 120: A friction ring 125 and a clamping nut 126 are provided inside the bell housing 124. The friction ring 125 is stepped and matches the upper inner wall of the bell housing 124. The toothed mandrel 122 passes through the bell housing 124 and extends out of the bell housing 124 to connect with the handwheel 121 and is fixed by the second fixing screw 123. The clamping nut 126 is connected to the internal thread of the inner wall of the bell housing 124 to clamp the toothed mandrel 122 so that it abuts against the friction ring 125. The bell housing base 127 is provided at the bottom of the bell housing 124 and is threadedly connected to the bell housing 124.

[0038] (3) Assembly of water outlet pipe assembly 130: Water outlet pipe base 131 and water outlet pipe 132 can be connected and fixed at the factory using locking screws 135.

[0039] (4) Overall Installation: After installing the wall-embedded valve body assembly 110 into the wall, insert the extended toothed rod 103 from the wall-embedded valve body assembly 110 into the toothed spindle rod 122 until the end face of the bell base 127 of the adjusting handwheel assembly 120 abuts against the end face of the extension nut 104. Then rotate the bell base 127 of the adjusting handwheel assembly 120, and through the threaded transmission, move the entire adjusting handwheel assembly 120 closer to the wall until the bell base 127 is flush with the wall. During the installation process, since the extended toothed rod 103 can slide on the toothed spindle rod 122, the overall installation depth can be effectively adjusted. Align the inlet of the outlet pipe assembly 130 with the outlet connector 105 and insert it until the end face of the outlet pipe base 131 is flush with the wall. Then tighten the two locking screws 134 to complete the installation.

[0040] By adjusting the installation position of the extended toothed rod 103 inserted into the toothed mandrel rod 122 and the installation positions of the water outlet connector 105 and the fixed connector 106, the following can be obtained: Figure 13 Installation at the maximum wall embedment depth shown (e.g., 90mm) or as... Figure 14 The minimum wall embedment depth shown is 75mm. Therefore, the wall-mounted concealed faucet 100 provided by this utility model has a large adjustable range of wall embedment depth, which can ensure the uniformity of installation within this range.

[0041] Among them, the wall-mounted valve body assembly 110, the adjusting handwheel assembly 120 and the outlet pipe assembly 130 are all shipped pre-assembled, which eliminates the need for additional assembly work for end users and plumbers, thus reducing the risk of parts being lost or damaged.
