Device of Cleaning Brush

Abstract

A cleaning brush comprising a carrier and a cleaning unit is provided. The cleaning unit comprises a plurality of cleaning beans set on a surface of the carrier in a spiral arrangement. A spiral coiling around the carrier from an end of the carrier to the other end is formed. A spiral curve path is formed to coil the carrier circumferentially by extendedly arranging the cleaning beans. Hence, the present invention uses the cleaning beans of the cleaning unit to be set on surface of the carrier. On rotating in a fixed direction, the spiral cleaning unit generates a flow field which not only comprises a vertical flow for an object to be cleaned but also a horizontal flow forming a parallel stream. Thus, dirt can be removed more easily than by using a traditional matrix cleaning device.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The present invention will be better understood from the following detailed description of the preferred embodiment according to the present invention, taken in conjunction with the accompanying drawings, in which

[0009] FIG. 1 is the view showing the preferred embodiment according to the present invention; and

[0010] FIG. 2 is the view showing the state-of-use.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0011] The following description of the preferred embodiment is provided to understand the features and the structures of the present invention.

[0012] Please refer to FIG. 1 and FIG. 2, which are a view showing a preferred embodiment according to the present invention; and a view showing a state-of-use. As shown in the figures, the present invention is a device of cleaning brush, comprising a carrier 10 and a cleaning unit 20. The carrier 10 and the cleaning unit 20 are foamed and formed into a whole one with a soft foam like a composite material, sponge, polyurethane (PU), polyvinyl alcohol (PVA) or a polymer material according to requirement.

[0013] The carrier 10 has a cylindrical shape with a sleeve unit 11 set at center.

[0014] The cleaning unit 20 is set on an outer edge of the carrier 10. The cleaning unit 20 comprises a plurality of cleaning beans 21 set on a surface of the carrier in a spiral arrangement to form a spiral coiling around the carrier 10 from an end to the other end. The cleaning beans 21 are protruded out a certain distance from the surface of the carrier 10 to form a spiral curve path 22 coiling the carrier 10 circumferentially by extendedly arranging the cleaning beans 210. An end surface of each one of the cleaning beans 21 has a concave arc 211 with a concave at center; and the concave arc 211 has a curvature of 7099 percent (%). Therein, the cleaning beans have pillar shapes, polygonal shapes, or a combination of pillar and polygonal shapes. Thus, a novel device of cleaning brush is obtained.

[0015] On using the present invention, one or a plurality of carriers 10 are combined with a related actuator (not shown in the figure) by the sleeve units 11. The actuator carries the carriers 10 by rolling, and moves according to the position and the requirement for cleaning status. Each one of the cleaning beans 21 of the cleaning unit 20 on the outer edge of the carriers 10 contacts a surface of a relevant precision electronic component 3 for processing required cleaning. In FIG. 2, during a horizontal cleaning motion, the precision electronic component 3 is assumed to rotate at the original place in a clockwise or counterclockwise direction while the cylindrical carrier 10 with the cleaning unit 20 spirally rotating too. Therein, the cleaning unit 20 spirally coiling the carrier 10 pushes dirt (e.g. particles) from an end of the carrier 10 to the other end (as shown by the black arrow 4 in FIG. 2) by using the spiral curve path 22 formed by extendedly arranging the cleaning beans 21 for coiling the carrier 10 circumferentially. Thus, the dirt is pushed directionally to provide a more effective cleaning efficiency. The trapped particles between the device of cleaning brush and the precision electronic component 3 are significantly reduced. Furthermore, because the concave arc 211 at the end surface of each one of the cleaning beans 21 has a curvature of 7090%, the cleaning beans 21 achieves large contact surface, fast cleaning efficiency and high effectivity of dirt removal.

[0016] To sum up, the present invention is a device of cleaning brush, where a plurality of cleaning beans of a cleaning unit is used to be set on a surface of a carrier in a spiral arrangement; on rotating in a certain direction, the cleaning unit having a spiral form set on a carrier generates a flow field which not only comprises a vertical flow for an object to be cleaned but also a horizontal flow forming a parallel stream; and, thus, dirt can be removed more easily than by using a traditional matrix cleaning device.

[0017] The preferred embodiment herein disclosed is not intended to unnecessarily limit the scope of the invention. Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
