Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In order to solve one or more technical problems in the prior art, the present invention provides a brush for cleaning a chip, referring to fig. 1 to 7, the brush comprising:

the base 100 is provided with a first end part 101 and a second end part 102 opposite to the first end part 101, the base 100 is provided with an accommodating cavity 103 extending from the first end part 101 to the second end part 102, the inner end 104 of the accommodating cavity 103 is spherical, and the side wall 105 of the accommodating cavity 103 is cylindrical;

after the bristles 200 are folded from the middle, the folded end 201 is inserted into the accommodating cavity 103, the folded end 201 abuts against the inner end 104 of the accommodating cavity 103, and the end part of the bristles 200 extends out of the accommodating cavity 103; and

the linear binding member 300, the linear binding member 300 passing through the folded end 201, binds the bristles 200 to the base 100.

A plurality of bristles 200 are folded in half from the middle and brought together to form a bristle tuft. The base 100 is used for fixing the bristles 200, and specifically, a part of the bristles 200 is accommodated in the accommodating cavity 103, the accommodating cavity 103 is filled with the bristles, and the other part of the bristles 200 extends out of the accommodating cavity 103. In some embodiments, the diameter of the cylindrical surface may be 8mm, the diameter of the bristles 200 may be 0.2mm, and the length of the bristles 200 extending out of the accommodating cavity may be about 10.5 mm. The end of the section of bristles 200 extending out of the receiving cavity 103 is flush, which is advantageous in that the end of the bristles 200 is in full contact with the chip, and thus, the cleaning is not in place, for example, the end of the bristles 200 can be cut flat by precise cutting. When the bristle 200 is folded in half, the bent end is a folded end 201. The folded bristles 200 have a U-shape through which the linear binding 300 passes. The inner end 104 of the accommodating cavity 103 is positioned in the base 100, and the cylindrical surface is connected with the spherical surface. Preferably, the spherical surface is a hemisphere geometrically obtained by cutting a plane through the center of a complete spherical surface. Of course, in some other embodiments, the spherical surface may geometrically be a smaller portion obtained by dividing a plane by the center of a complete spherical surface.

The brush for cleaning the chip of the embodiment has at least the following technical effects: instead of the traditional bonding and fusion connection mode, the folded bristles 200 are folded in half and then the folded ends 201 are bound with the base 100, so that the bristles 200 are effectively prevented from falling off; the bristles 200 are mainly made of elastic polymer wires, so that after the bristles 200 are folded in half, the folded end 201 is bent, the folded end 201 abuts against the spherical inner end 104 of the accommodating cavity 103, and the bent folded end 201 is just attached to the spherical surface, so that a space allowing the bristles 200 to retract does not exist in the accommodating cavity 103, and the end parts of the bristles 200 are prevented from being uneven; when the bristles 200 penetrate through the accommodating cavity 103, the cylindrical surface forms constraint on the bristles 200, and the bristles extending out of the accommodating cavity 103 are gathered into a cylindrical shape, namely the ends of the bristles 200 are gathered densely, so that the cleaning power is higher.

In some embodiments, referring to fig. 4-7, the base 100 further has two through holes 106 extending from the inner end 104 of the accommodating cavity 103 to the second end 102, the linear binding member 300 passes through the folded end 201, and two ends of the linear binding member 300 are connected together after passing through the two through holes 106 respectively. The present embodiment provides a specific manner in which the linear binding 300 binds the half-folded end 201 to the base 100. Optionally, the linear binding 300 is a wire or wire, such as stainless steel wire or otherwise. Due to the metal characteristic of the metal wire or the metal wire, both ends thereof are easily twisted, so that the brush bristles 200 are conveniently and rapidly bound to the base 100. In addition, the two ends of the metal wire or the metal wire are twisted tightly to have large binding force, so that the brush hair is firmly bound with the base, and the brush hair 200 is not easy to fall off.

In some embodiments, referring to fig. 2, the end surface of the second end portion 102 is provided with a groove 107, and the connecting head is accommodated in the groove 107 after the two ends of the linear binding member 300 are connected. For example, two through holes 106 are communicated with the groove 107, and the linear binding member 300, such as a metal wire or a metal wire, is wrapped and twisted at two ends and then the connector is bent and accommodated in the groove 107. The groove 107 of the present embodiment prevents the connection head of the linear binding 300 from protruding out of the end surface of the second end portion 102 to affect the installation of the brush to the device.

In some embodiments, the cylindrical surface has an axial length of 7 to 8 mm. The cylindrical surface with the length can better restrain and gather the bristles 200, and is favorable for the bristles 200 extending out of the accommodating cavity 103 to gather to form a cylindrical shape.

In some embodiments, referring to fig. 2 and 5, the base 100 has a first side 108, a second side 109, a third side 110, and a fourth side 111 connected end to end, each two adjacent sides being perpendicular to each other, the four sides extending from the second end 102 toward the first end 101. The first side 108, the second side 109, the third side 110, and the fourth side 111 define at least a section of the base 100 having a rectangular or square shape that is shaped to mate with a shape of a device receiving a brush to facilitate mounting of the base 100 to the device.

In certain embodiments, the first side 108, the second side 109, the third side 110, and the fourth side 111 extend 12.75-15.5mm in length. The brush of the present embodiment has an appropriate installation length.

In some embodiments, the base 100 has an overall shape of a cuboid or a cube, while in some other embodiments, the first end 101 has an outer shape of a cylinder and the other portion has an outer shape of a cuboid or a cube.

In some embodiments, the gap between the bristles 200 in the bristles 200 extending outside the housing cavity 103 does not exceed the diameter of a single bristle 200. The bristles 200 are densely filled in the accommodating cavity 103, the bristles 200 extending out of the accommodating cavity 103 have enough density, on one hand, the cleaning is not clean due to omission when the chip is cleaned, and on the other hand, the bristles 200 have large strength when the chip is cleaned.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
