Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to the attached drawings 1-3 of the specification, the drawing head with the self-cleaning function comprises a shell, a shell fixing nut for fixing the drawing head, a water channel main body, a water outlet terminal switching assembly, a radial linkage piece, a linkage rocker, an axial linkage piece, a first spring, a second spring, a movable surface cover and a fixed surface cover. The water channel main body, go out water terminal switching module, radial linkage piece, linkage wane, axial linkage piece, first spring and second spring are located inside the shell and through activity face lid and fixed surface lid right the shell front end seals. The first key and the second key protrude out of the side part of the shell main body.

The periphery of the fixed surface cover is uniformly distributed with a plurality of groove positions, the periphery between the groove positions is provided with an inclined slope surface, and the movable surface cover is connected with the axial linkage piece and can axially move relative to the fixed surface cover. The radial and axial linkage members are mutually matched through the slope with the inclination angle and can move relatively. The fixed surface cover is installed on the water channel main body and is fixed relative to the water channel main body. The movable surface cover, the axial linkage piece and the second spring are sequentially arranged on the water channel main body and can axially move relative to the water channel main body. The radial linkage piece and the axial linkage piece are matched with each other through the slope surface with the inclination angle and can move mutually, and the radial linkage piece and the axial linkage piece are always kept in contact in the moving process. The linkage wane is used for making the water terminal remain single water selection all the time.

In one embodiment, as shown in the specification and attached to fig. 2, the water outlet terminal formed by the fixed surface cover and the movable surface cover has two water outlet ends, wherein the first water outlet end is positioned in a gap between the movable surface cover and the fixed surface cover, and the second water outlet end is positioned in the middle of the fixed surface cover.

Referring to fig. 4(a) - (c) of the specification, the water outlet terminal switching assembly is mounted on the water channel main body, at least two water outlet channels are arranged in the water channel main body, the water outlet terminal switching assembly is connected with the first key and used for switching a water channel in the water channel main body, and meanwhile, the switching mode also has a reset function and default water outlet selection. Preferably, the second water outlet end water outlet is a default water outlet selection. When the first key is pressed, the water outlet terminal switching component switches the default water outlet from the second end to the water outlet from the first end as shown in the description of fig. 4(a) - (b); the second key is used for starting the self-cleaning function of the pull head, is sequentially arranged on the water channel main body together with the radial linkage piece, the first spring and the linkage rocker, and can radially move relative to the water channel main body. As shown in fig. 4(b) - (c) of the specification, when the second button is pressed, the radial linkage piece presses the linkage rocker to switch the water channel, so that at least one water channel in the water channel main body is kept unblocked, water is discharged from a groove on the periphery of the fixed surface cover, and meanwhile, the axial linkage piece is driven by the radial linkage piece to move relative to the fixed surface cover, so that the movable surface cover is separated from the fixed surface cover, a large gap is generated, and large-particle impurities in the water channel are taken out under the driving of water flow impact, and the cleaning is completed. When the second key is released, the movable surface cover resets under the action of the second spring and drives the axial linkage piece to reset, and meanwhile, the radial linkage piece resets under the action of the first spring.
