Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, specifically to a faucet. Background Technology

[0002] A faucet, a common fluid control device, has a basic structure consisting of a valve seat, a valve core, and a threaded tube. The valve core is housed inside the valve seat and is fixed to the mounting surface via an outer flange. The threaded tube connects to the bottom of the valve seat and extends below the mounting surface, engaging with the threaded seat to clamp the mounting surface between the outer flange and the threaded seat. Additionally, a handle seat is connected to the outer flange, and a user-operated handle is mounted on the handle seat. This handle, via a transmission mechanism, is linked to the valve core to control the opening, closing, and regulation of water flow.

[0003] In existing technologies, the connection between the handle seat and the outer flange often employs a threaded structure, such as the solutions disclosed in patents CN103574146 and US5947149. For example, US5947149 details an "invisible faucet handle connection" in which the handle hub is connected to the bore flange (equivalent to the outer flange) via threads to secure the handle assembly to the valve body. While this threaded connection method can conceal external fasteners and improve aesthetics, its disassembly and assembly process has significant drawbacks: threaded engagement requires multiple rotations, resulting in lengthy installation or disassembly times and demanding sufficient operating space and tools. During maintenance or component replacement, repeated tightening can easily lead to thread wear, decreased sealing performance, and even component jamming, increasing maintenance and time costs.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] See Figures 1-8A faucet includes a valve body 1, a handle assembly 2, and a handle connecting mechanism. The valve body 1 includes a valve seat 11, a valve core 12, a pressure cap 13, a threaded tube 14, and a connecting seat 15. The valve core 12 is disposed within the valve seat 11, and the pressure cap 13 is connected to the valve seat 11 to press and fix the valve core 12. The threaded tube 14 is fixedly connected to the lower end of the valve seat 11, and the connecting seat 15 is fixedly connected to the upper end of the valve seat 11. During installation, the threaded tube 14 passes through a mounting hole in the countertop, corresponding to the area below the countertop. A threaded seat is then screwed onto the threaded tube 14, and the threaded seat can move up and down on the threaded tube 14 to correspond to the area below the countertop.

[0032] The handle connection mechanism includes a first connector 31 and a second connector 32. The first connector 31 is connected to the upper end of the valve seat 11 of the valve body 1. The first connector 31 is annular, and the upper end of the valve seat 11 is threaded to the inner circumferential wall of the first connector 31. The first connector 31 can serve as a flange of the valve body 1, abutting against the top of the platform.

[0033] The handle assembly 2 includes a handle seat 21 and a handle 22. The handle 22 is rotatably mounted on the handle seat 21. The second connector 32 can be attached to the handle seat 21. The second connector 32 can be detachably connected to the handle seat 21 by means of threads or other means of non-detachable means of adhesive bonding or interference fit. The second connector 32 is configured to adapt to handle seats 21 of different styles of handle assemblies 2. The second connector 32 is operably detachably connected to the first connector 31. The handle 22 is connected to the valve shaft 121 of the valve body 1.

[0034] The handle seat 21 includes a lower seat 211 and an upper seat 212. The upper seat 212 is connected to the upper end face of the lower seat 211, and the diameter of the upper seat 212 is smaller than the diameter of the lower seat 211. The upper seat 212 includes a connecting channel 2121, and the lower end of the handle 22 is rotatably disposed within the connecting channel 2121. The lower end of the handle 22 also includes a connecting feature 221 for connecting to the valve shaft 121. In this embodiment, the connecting feature 221 is a spline. The second connecting member 32 is threaded to the inner wall of the lower seat 211. During connection, the opening of the lower seat 211 is installed facing the valve shaft 121, so that the valve shaft 121 is connected to the connecting feature 221. Then, the handle assembly 2 is connected to the valve body 1 through the connection of the second connecting member 32 and the first connecting member 31.

[0035] In this embodiment, the second connector 32 includes a connected position and a disassembled position relative to the first connector 31. The second connector 32 can rotate relative to the first connector 31 to change between the connected position and the disassembled position. The user can operate the handle base 21 to rotate, thereby connecting and separating the second connector 32 from the first connector 31.

[0036] The second connector 32 also includes a detached position relative to the first connector 31, and the second connector 32 is axially movable relative to the first connector 31 to change between the detached position and the disassembled position. During installation, the second connector 32 first moves from the detached position to the disassembled position, and then moves from the disassembled position to the connected position. Conversely, during disassembly, the second connector 32 first moves from the connected position to the disassembled position, and then moves from the disassembled position to the detached position.

[0037] Specifically, the outer peripheral wall of the first connector 31 includes a plurality of connecting blocks 311 arranged at intervals along the circumferential direction, with a spacing groove 312 formed between adjacent connecting blocks 311. Each connecting block 311 includes a slot 3111 extending along the circumferential direction. The inner peripheral wall of the second connector 32 includes a plurality of locking blocks 321 arranged at intervals along the circumferential direction. When the second connector 32 moves from the detached position to the disassembled position, the locking blocks 321 move axially within the spacing grooves 312 to correspond to the slots 3111 circumferentially. When the second connector 32 moves from the disassembled position to the connected position, the locking blocks 321 move circumferentially to insert into the slots 3111. In this embodiment, the inner peripheral wall of the second connector 32 also includes a limiting block 322. When the second connector 32 moves to the connected position, the limiting block 322 abuts against the connecting blocks 311 to restrict the circumferential rotation of the second connector 32.

[0038] The second connector 32 includes a first positioning ring 323, and the first connector 31 includes a second positioning ring 313. When the second connector 32 is in the connection position and the disassembly position, the first positioning ring 323 is sleeved on the outside of the second positioning ring 313. One of the inner wall of the first positioning ring 323 and one of the outer wall of the second positioning ring 313 are provided with a positioning protrusion 324, and the other of the inner wall of the positioning ring and the outer wall of the second positioning ring 313 are provided with at least two positioning recesses 314. The first positioning ring 323 rotates relative to the second positioning ring 313 so that the positioning protrusion 324 corresponds to one of the positioning recesses 314, respectively, to correspond to the connection position or the disassembly position. The first positioning ring 323 includes an elastic arm 3231 capable of radial elastic deformation, and the positioning protrusion 324 is disposed on the elastic arm 3231.

[0039] In this embodiment, the second connector 32 includes a surrounding wall 325 and a top wall 326. The top wall 326 is connected to the upper side of the surrounding wall 325 and extends radially inward. The top wall 326 defines the first positioning ring 323, which includes the positioning protrusion 324. The second positioning ring 313 includes the positioning recess 314. In this embodiment, the top wall 326 has a through hole 3232 radially outward of the positioning protrusion 324 to form the elastic arm 3231 between the through hole 3232 and the positioning protrusion 324.

[0040] The top wall 326 includes an elastic abutment arm 3261, which abuts against the first connector 31 to drive the second connector 32 and the first connector 31 to abut axially. In this embodiment, the elastic abutment arm 3261 abuts downward against the first connector 31, and the locking block 321 is driven to press against the upper wall of the locking groove 3111, which can prevent the second connector 32 from moving up and down relative to the first connector 31.

[0041] During connection, the second connecting member 32 is threaded to the lower seat 211, and the handle 22 is rotatably connected to the upper seat 212. The valve body 1 is threaded to the first connecting member 31, and the valve body 1 is then fixed to the table surface. The handle assembly 2 is moved from top to bottom so that the locking block 321 corresponds to the spacer groove 312, until it moves from the detached position to the disassembled position. Then, the handle seat 21 is rotated, and the locking block 321 is inserted into the locking groove 3111. At this time, the positioning protrusion 324 moves from one positioning recess 314 to another positioning recess 314, resulting in a change in feel to remind the user that the rotation is complete. In addition, the limiting block 322 can also restrict the rotation of the second connecting member 32. When disassembly is required, simply reverse the operation. The second connector 32 can be used as a universal component to adapt to different types of handle assemblies 2. That is, the interface between the handle base 21 and the second connector 32 is fixed. Therefore, as long as different handle assemblies 2 have the same interface, they can use the second connector 32 to connect to the first connector 31.

[0042] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
