Description

Water outlet assembly of wall-buried faucet

Technical Field

The application belongs to the technical field of combined components of a faucet, and particularly relates to a water outlet assembly of a wall-buried faucet.

Background

A typical wall-buried faucet is characterized in that a valve assembly is arranged in a wall and is used for receiving cold water and hot water, a cold water control valve seat and a hot water control valve seat are arranged on the valve assembly and can be respectively provided with a valve core, a cold water control handle and a hot water control handle are arranged outside the wall and are used for being arranged on the valve core so as to control the flow rate of the cold water and the hot water entering a mixing chamber of the valve assembly, further control the mixing proportion and the water outlet temperature, at least one mixed water outlet pipe is arranged on the valve assembly and protrudes outside the wall so as to be provided with a faucet water outlet component which is connected with a faucet model in appearance, mixed water is guided to flow out to form faucet water, two mixed water outlet pipes are arranged on some valve assemblies, and the other mixed water outlet pipe can be provided for being connected with a shower component arranged above the outside the wall so as to form shower water outlet, wherein a pull rod is arranged on the faucet water outlet component so that a user can freely switch and control faucet water outlet or shower water outlet.

The existing faucet water outlet assembly is more difficult to install and operate than the problem of human scale disease, and has the defects of poor sealing generally, for example, the faucet assembly disclosed in U.S. patent No. 8613294B2 is provided, and the faucet assembly comprises a connecting piece, which is used for penetrating and sleeving a mixed water outlet pipe protruding from the interior of a wall, and is radially screwed on the connecting piece by using a bolt and then is abutted against the peripheral wall of the mixed water outlet pipe, so that the connecting piece is locked on the mixed water outlet pipe, then a connecting pipe is penetrated and sleeved outside the connecting piece, so as to be used for connecting the mixed water outlet pipe, and then a faucet body is screwed and locked outside the connecting pipe, so that mixed water from the mixed water outlet pipe flows to a water outlet of the faucet body through the connecting pipe to form faucet water. The faucet body is provided with a pull rod, so that the mixed water flowing to the water outlet can be controlled by a switch, and the aim of switching faucet water outlet and shower water outlet is achieved.

Considering the leak-stopping tightness, the inside of the connecting piece is nested with a sealing ring to prevent the mixed water from leaking outwards from the gap between the inner peripheral wall of the connecting piece and the outer peripheral wall of the mixed water outlet pipe, and a sealing sleeve is clamped between the outer side end of the connecting piece and the opposite part of the connecting pipe to further prevent the mixed water from leaking outwards from the gap between the outer peripheral wall of the connecting piece and the inner peripheral wall of the connecting pipe.

However, the above-mentioned seal structure design is not ideal in practical use, and the main reason is that: in order to facilitate assembly, after the connecting piece is sleeved outside the mixed water outlet pipe, a small assembly gap is formed between the connecting piece and the mixed water outlet pipe, at the moment, a fixing mode of the connecting piece and the mixed water outlet pipe, which is propped against the outer peripheral wall of the mixed water outlet pipe, is radially screwed by utilizing a bolt, although a certain fixing effect can be achieved, the connecting piece and the mixed water outlet pipe are deviated and cannot be coaxial, as a result, a uniform sealing effect cannot be generated between the sealing ring and the sealing sleeve at each position, specifically, a loose fit phenomenon is generated on one side opposite to the bolt, a tight fit phenomenon is generated on the opposite side, the leakage sealing effect is easily influenced, and the overtightening fit also easily causes structural damage and improper deformation phenomenon after a period of time, and the service life of the sealing ring and the sealing sleeve is influenced.

Secondly, radial screw locking is performed on the connecting piece by using the bolt, so that the manufacturing cost of the bolt component, the processing cost of the screw hole on the connecting piece, the time cost of the assembly operation of the two components and the inconvenience of the assembly operation are increased. The way of fastening the radial screw lock of the connecting piece to the mixed water outlet pipe by using the bolt is a common practice in the current technical field, and is also commonly found in related patent technical documents, such as the invention patents of U.S. Pat. No. 3,218B 2 and U.S. Pat. No. 3,62B 2, etc., the same or similar assembly structure is disclosed, so how to further improve the water outlet assembly of the existing faucet so as to solve the above-mentioned situations of easy leakage and inconvenient assembly, and the necessity is quite high.
