Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, specifically to a wall-mounted faucet and its handle assembly. Background Technology

[0002] Wall-mounted faucets typically consist of a valve body, a valve core, and an external handle. The valve body is embedded in the wall, the valve core regulates water flow and temperature, and the handle is the user-operated component. Current technology employs a coaxial dual-control valve core structure, where the outer valve shaft regulates the mixed water temperature, and the inner valve shaft controls the switching of water flow modes. The coaxial dual-control handle connects the inner valve shaft to the inner handle and the outer valve shaft to the outer handle, then is fixed to the valve seat via a connector, forming a linked control system. However, because this handle structure comprises three main parts—the inner handle, the outer handle, and the connector—the numerous assembly gaps between these parts lead to insufficient overall structural stability. During use, problems such as handle wobbling, abnormal noises, and surface scratches can easily occur, affecting the operating feel and product lifespan. Utility Model Content

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] See Figures 1-8 A wall-mounted faucet includes a faucet body 1, a panel 2, and a handle assembly 3. The faucet body 1 is embedded in the wall, and the panel 2 is mounted on the wall surface. The faucet body 1 includes a valve seat 11 and a valve core 12, with the valve core 12 disposed within the valve seat 11. The valve seat 11 is disposed within the wall and includes an inlet seat and an outlet seat. The inlet seat is connected to an external water source, and the outlet seat is connected to a water outlet device (e.g., a handheld shower head, a head shower head, etc.) via a pipe. The valve core 12 includes a valve shaft extending out of the wall surface. The valve shaft includes an inner valve shaft 121 and an outer valve shaft 122 coaxially arranged, with the outer valve shaft 122 surrounding the inner valve shaft 121.

[0034] The handle assembly 3 is connected to the valve shaft to control the outer valve shaft 122 and the inner valve shaft 121. The handle assembly 3 includes a handle connecting seat 31, a first handle 32, a second handle 33, a first bushing 34, a second bushing 35, a first positioning pad 36, and a second positioning pad 37. The handle connecting seat 31 is sleeved on the outside of the first bushing 34. The handle connecting seat 31 and the first bushing 34 are respectively positioned against one end face of the first positioning pad 36, and the first handle 32 is pressed and fixed against the other end face of the first positioning pad 36. The first bushing 34 is sleeved on the outside of the second bushing 35. The first bushing 34 and the second bushing 35 are respectively positioned against one end face of the second positioning pad 37, and the second handle 33 is pressed and fixed against the other end face of the second positioning pad 37. The first bushing 34 is used to connect the first operating part of the wall-mounted faucet (e.g., the outer valve shaft 122), and the first handle 32 drives the first bushing 34 to rotate through the first positioning pad 36. The second bushing 35 is used to connect the second operating part of the wall-mounted faucet (e.g., the inner valve shaft 121). The second handle 33 drives the second bushing 35 to rotate via the second positioning washer 37. Both the first positioning washer 36 and the second positioning washer 37 are wear-resistant washeres. The first handle 32 and the first positioning washer 36 are connected by friction, and the first positioning washer 36 and the first bushing 34 are also connected by friction. When the first handle 32 rotates, it can drive the first bushing 34 to rotate. The first bushing 34 and the outer valve shaft 122 are connected by a spline. The second handle 33 and the second positioning washer 37 are connected by friction, and the second positioning washer 37 and the second bushing 35 are also connected by friction. When the second handle 33 rotates, it can drive the second bushing 35 to rotate. The second bushing 35 and the inner valve shaft 121 are connected by a spline. The first bushing 34 and the second bushing 35 share one end face of the second positioning washer 37 as a positioning surface, which can eliminate the cumulative tolerance of the thickness tolerance of the second positioning washer 37 on the entire handle assembly 3 and reduce the axial clearance between the first bushing 34 and the second bushing 35 along the handle assembly 3. The first bushing 34 and the handle connecting seat 31 share one end face of the first positioning washer 36 as a positioning surface, which can eliminate the cumulative tolerance of the thickness tolerance of the first positioning washer 36 on the entire device and reduce the axial clearance between the first bushing 34 and the handle connecting seat 31 along the handle assembly 3. Therefore, the handle feel can be improved, and after fixing, handle shaking and scratching can be avoided.

[0035] In this embodiment, the handle connecting seat 31 and the first bushing 34 are respectively positioned and abutted against the bottom end face of the first positioning pad 36, and the first handle 32 is pressed and fixed against the top end face of the first positioning pad 36.

In this embodiment, the first bushing 34 is provided with a first positioning surface 341, a second positioning surface 342, and a third positioning surface 343 from top to bottom; the second bushing 35 is provided with a top positioning surface 351; the handle connecting seat 31 is provided with a first seat positioning surface 311 and a second seat positioning surface 312 from top to bottom; the first positioning surface 341 and the top positioning surface 351 are respectively positioned and abutted against the bottom end surface of the second positioning pad 37; the second positioning surface 342 and the first seat positioning surface 311 are respectively positioned and abutted against the bottom end surface of the first positioning pad 36; the third positioning surface 343 is positioned and abutted against the second seat positioning surface 312.

[0036] A first flexible ring 352 is provided on the lower side of the second bushing 35. The first flexible ring 352 is disposed between the inner wall of the first bushing 34 and the lower side of the second bushing 35. When the first positioning surface 341 and the top positioning surface 351 are respectively positioned and abutted against the bottom end surface of the second positioning pad 37, the second bushing 35 presses upward against the first flexible ring 352 to compensate for the vertical gap between the first bushing 34 and the second bushing 35.

[0037] Specifically, the first bushing 34 is sleeve-shaped, and its upper end face defines the first positioning surface 341. The diameter of the upper end of the first bushing 34 is smaller than other parts to form a first constriction portion 344, which forms a first step 3441, defining the second positioning surface 342. The lower end of the first bushing 34 extends radially to form a first annular flange 345, and its upper end face forms the third positioning surface 343. The second bushing 35 is sleeve-shaped, and its upper end diameter is smaller than other parts to form a second constriction portion 353, which forms a second step 3531, defining the top positioning surface 351.

[0039] The first bushing 34 includes a second through hole 347. The upper end of the second bushing 35 is correspondingly disposed on the second through hole 347. The second constricted portion 353 extends out of the second through hole 347 and is inserted into the second handle 33. The handle assembly 3 includes a second fastener 39, which securely connects the second handle 33 and the second bushing 35. The second fastener 39 is a screw. The lower part of the second bushing 35 has an opening. The screw is inserted into the second bushing 35 from bottom to top to pass through the second bushing 35 and securely connect to the second handle 33.

[0040] The handle connector 31 includes a seat body 313 and a connecting body 314. The connecting body 314 is connected to the lower end of the seat body 313 and is threadedly connected to the wall-mounted faucet.
