Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It should be noted that the described embodiments are only some embodiments of the present application, and not all embodiments, and that the following description of at least one exemplary embodiment is merely illustrative in nature and should not be taken as limiting the application and its application.

Examples:

as shown in fig. 1 and 2, the embodiment provides a convenient-to-use board washing head device, which comprises a liquid injection pipe 1 and a waste liquid pipe 2, wherein the liquid injection pipe 1 and the waste liquid pipe 2 are arranged together in a vertically stacked manner;
