the water outlet assembly comprises an upper cover; the lower cover is connected with the upper cover; the water outlet nozzle support is arranged between the upper cover and the lower cover and is arranged separately from the lower cover; and the water outlet nozzle is arranged on the water outlet nozzle bracket.

In the water outlet assembly, the water outlet nozzle is arranged on a water outlet nozzle support, and the water outlet nozzle support and the lower cover are arranged in a split mode. Therefore, the water outlet nozzle can be firstly arranged on the support, the water outlet nozzle support is arranged on the upper cover or the lower cover, and the water outlet nozzle support is used as an installation structure of the water outlet nozzle to fix the water outlet nozzle, resist possible impact born by the water outlet nozzle and absorb part of heat emitted by the water outlet nozzle. As a part which is often impacted and corroded by heat, the water outlet nozzle bracket has certain vulnerability and is separately arranged on the lower cover to be replaced when necessary. If the spout is fixed by a fixing structure formed on the lower cap, it is a part of the lower cap that is subject to impact force and thermal erosion, and if the part of the lower cap is damaged, it may be the lower cap that needs to be replaced.

In addition, the split design mode is convenient for installing the water outlet nozzle, the water outlet nozzle and the bracket can be firstly assembled into a component, then the water outlet nozzle is installed between the upper cover and the lower cover, a link is added in an assembly chain, the optional assembly mode is added, and an installation component which is not suitable for being formed on the water outlet nozzle can be arranged on the water outlet nozzle component. Moreover, the mode is also favorable for disassembly, the water outlet nozzle is small in size and generally has a short and small tubular structure, the water outlet nozzle is installed through the water outlet nozzle support, when the water outlet nozzle is disassembled, the water outlet nozzle and the water outlet nozzle support can be detached from the upper cover and the lower cover together, then the water outlet nozzle and the water blowing nozzle support can be separated from an external opening space, and the water outlet nozzle is more convenient.

In a preferred implementation manner, the water outlet nozzle is mounted on the water outlet nozzle bracket through an elastic buckle structure;

the water outlet assembly further comprises a stopping structure for stopping the elastic buckling structure from loosening.

The water outlet nozzle and the water outlet nozzle support are fixed through the elastic clamping structure, and the structure can support convenient installation and disassembly. In connection with the features of the above-mentioned solution, it is advantageous to form the mounting structure on a nozzle holder which can be a wearing part or a replaceable part.

In addition, the mounting structure of the elastic buckle may not be stable enough, and a stop structure is additionally arranged, so that the mounting stability can be improved. The stop structure can be used for simultaneously mounting the water outlet nozzle support on the upper cover or the lower cover at intervals, or can be a separately arranged stop structure, but the stop structure is attached to the upper cover and/or the lower cover.

In a preferred implementation manner, the faucet bracket comprises a ring part wrapped outside the faucet and a limiting part formed on the inner wall of the ring part;

the elastic buckle structure comprises a clamping groove formed in the outer wall of the water outlet nozzle, and an elastic buckle formed in the limiting part and matched with the clamping groove; or

The contact area between the water outlet nozzle support and the groove is reduced through the convex rib structure, so that the pressure is increased, the mounting reliability is improved, a certain sealing effect is provided, and foreign objects are prevented from entering the water outlet assembly to a certain extent.

In a preferred implementation manner, the limiting portion and/or the ring portion are/is formed with notches which are uniformly distributed along the circumferential direction of the ring portion and extend along the axial direction of the ring portion.

The gap provides a space for retreating and avoiding, and is beneficial to the elastic deformation and the release of elastic force generated by the water outlet nozzle bracket when the water outlet nozzle and the water outlet nozzle bracket are installed. The requirement on the elasticity of the water outlet nozzle bracket material is reduced. In some faucet supports made of relatively flexible materials, such notches may not be provided.

In a preferred implementation, the faucet support further comprises a flange extending to the outside of the ring part;

the upper cover is provided with a support rib which presses against the flanging;

the upper cover is connected with the lower cover through a buckling structure and/or a threaded connection structure.
