In a preferred embodiment of the present invention, the water outlet of the nozzle portion of the valve core is unevenly disposed around the side surface, and the water outlet direction of each water outlet is perpendicular to the axial direction of the through hole.

In a preferred embodiment of the present invention, the water outlet of the nozzle portion of the valve core is unevenly disposed around the circumference, and the angle between the water outlet direction and the axial direction of the through hole is different between each water outlet. The included angle range is greater than 45° and less than 90°.

In a preferred embodiment of the invention, the spool is made of a soft material. The soft material may be a material such as rubber.

The advantages of the invention are:

The water spray cleaning brush of the present invention comprises a brush body, the outer surface of the brush body is provided with bristles, the brush body area is provided with a valve core protruding from the brush body, and the side ring of the protruding portion is provided with a plurality of water outlets. In the water spray cleaning, the water flow direction is dispersed laterally at multiple angles, fully soaking all parts of the bristle area, and at the same time, due to the blockage of the bristles, the water on the bristles can be washed away by the root hair of the bristles by the pressure of the water. . Therefore, the bristles of the bristle area are maintained in a sufficiently wet state and in a clean state, and the cleaning efficiency is high, and water is saved.

The brush body of the present invention has a cylindrical shape or an elliptical shape or a capsule shape or a square shape. The way in which the bristles are implanted on the outer surface of the brush is a multi-faceted wrap. Therefore, the entire outer portion of the brush body has a shape of a thorn-like shape, which facilitates cleaning of the uneven face.

The valve core of the present invention is made of a flexible material and does not damage the vehicle body during washing.

Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

detailed description

Referring to FIG. 1 to FIG. 4, the water spray cleaning brush of the present invention comprises a brush body 1 which is in the shape of a waist drum, and an auxiliary fixing portion 6 is provided on one side, and the auxiliary fixing portion 6 is formed by a side symmetrical recess, and the side surface is formed. A through hole 2 is formed through the brush body, and one end of the through hole 2 is a water inlet end and the other end is a water outlet end. Except for the surface where the water inlet end is located, the rest of the outer surface of the brush body 1 is planted with bristles 3, that is, the bristles are implanted in a multi-faceted manner. For the sake of simplicity, only the bristles are drawn at both ends of the brush body in Fig. 1, and the remaining bristle portions are replaced only by the bristles mounting holes 4. The outlet end is located in the bristle area. A valve body 5 is provided in the through hole 2, and the valve core 5 is protruded from the brush body 1.
