Abstract

A cleaning brush for eliminating static electricity, including a conductive housing, wherein a containing slot is on a bottom surface of the conductive housing, and the conductive housing has two opposite end walls; and a conductive brush, which is embedded in the containing slot of the conductive housing, and is electrically connected to the conductive housing. Thus, the cleaning brush have both the functions for eliminating static electricity and removing dust.

Claims

1. A cleaning brush for eliminating static electricity, comprising:

a conductive housing, having a containing slot on a bottom surface of the conductive housing, and the conductive housing has two end walls facing each other; and

a conductive brush, located in the containing slot, and is electrically connected to the conductive housing, wherein the conductive brush comprises;

a base;

a conductive sheet, disposed on a top surface of the base; and

a plurality of conductive fibers, wrapped around a left side and a right side of the base and around the top surface of the conductive sheet in a U-shaped form, wherein the base, the conductive sheet, and a portion of the conductive fibers are placed in the containing slot, another portion of the conductive fibers protrudes from the bottom surface of the conductive housing in a left row and a right row, and the conductive sheet and the conductive fibers are electrically connected to the conductive housing, wherein the conductive housing comprises a housing body and a conductive outer housing covering an outer surface of the housing body, and the housing body has a perforation;

the base has a mounting hole, and the conductive sheet has a through hole;

the cleaning brush further has a conductive rod, the conductive rod has a first end portion and an opposite second end portion, the conductive rod passes through the perforation of the housing body and the through hole of the conductive sheet, and is fixed in the mounting hole of the base by the first end portion, and the second end portion pushes against the conductive outer housing;

the conductive sheet and the conductive fibers are electrically connected to the conductive outer housing of the conductive housing via the conductive rod.

2. A cleaning brush for eliminating static electricity, comprising:

a conductive housing, having a containing slot on a bottom surface of the conductive housing, and the conductive housing has two end walls facing each other;
