Abstract

The present invention is directed to an improved rotary helical brush comprising a rotary axis and two helical brushing members sliding across the rotary axis, the helical brushing members having bristles on the surface of their corresponding continuous spiral frames. It is implanted into (bristles) and assembled by rotating in opposite directions. Rings of one of the two helical brushing members are alternately arranged with respect to rings of the other helical brushing members, and the degree of inclination of the bristles on each ring of the helical frames is between the bristles on each ring and the surface of the plate being cleaned. Is increased to increase the contact area. This causes the rotary axis to rotate slowly to reduce centrifugal forces and vibrations, thereby reducing scratches created on the surface of the plate.

The present invention relates to an improved rotary spiral brush for cleaning the surface of a plate, in particular to an improved rotary spiral brush with a spiral brushing member.

There are various rotary cleaning or brushing apparatuses, and typical apparatuses of this kind include glass curtain wall cleaning apparatuses for buildings or cleaning apparatuses for the scientific and technical industries, etc., and rotary cleaning or brushing apparatuses are used for removing dust. Is moved on the surface of the plate.

1 and 2 show a conventionally used rotary brushing mechanism having a helical brushing member 92 sliding across a rotary axis 91, wherein the helical brushing member 92 is formed of a continuous spiral frame 921. Implanted with bristles 922 on the surface. The helical brushing member 92 is rotated by the rotary shaft 91 so that the bristles 922 move on the surface of the plate to be cleaned, thus providing a cleaning effect.

Since each ring of the continuous spiral frame 921 of the helical brushing member 92 is integral with the other ring as shown in FIG. 2, the two ends a1, b1 of each ring have a small degree of inclination. Forming an inclined section, this reduces the contact area between the surface of the plate being cleaned and the bristles on each ring, thereby degrading the cleaning effect. In order to achieve an overall cleaning effect, the rotational speed of the rotary shaft 91 should increase what is given to the bristles 922 to clean the surface of the plate as a whole.

However, by increasing the centrifugal force of the helical brushing member 92 at high speeds, vibrations are created and imparted to the plate being created by creating scratches. When the scientific product (such as the panel of the display) is cleaned, the scratches create serious optical defects to be solved.

With respect to the above-mentioned drawbacks of the prior art, the present invention includes a rotary shaft and first and second helical brushing members that slide across the rotary axis so that rotation of the rotary shaft moves by rotating the two helical brushing members. An improved rotary helical brush is provided, wherein the two helical brush members are assembled by bristles implanted on the surface of their corresponding continuous helical frames and rotated in opposite directions, whereby the rings of the first helical brush member are Alternately arranged with respect to the rings of the second helical brushing member. The degree of inclination of the bristles on each ring of the helical frames is increased to increase the contact area between the bristles on each ring and the surface of the plate being cleaned.

The present invention provides an improved rotary helical brush in which the area of contact between the bristles on each ring of the helical frame and the surface of the plate to be cleaned is increased, in which the rotary axis reduces the problems of centrifugal force and vibration of the helical brush members. It rotates slowly, thereby reducing the scratches produced on the surface of the plate.

The present invention can be understood with the structure and effect after reading the detailed description of the suitable embodiment with reference to the accompanying drawings.

3 to 5, the present invention is directed to an improved rotary helical brush that mainly includes a rotary shaft 10 and first and second helical brush members 21, 22.

The first and second spiral brush members 21, 22 slide over the rotary axis 10, whereby when the rotary axis 10 is rotated, the two spiral brush members 21, 22 are moved. It is rotated and moved.

The first and second spiral brushing members 21, 22 have their corresponding continuous spiral frames 211, 221 and bristles on the surface of their corresponding continuous spiral frames 211, 221. (bristles) 212, 222. 4 and 5, the first helical brushing member 21 and the second helical brushing member 22 are assembled by rotating in opposite directions to each other, and the degree of inclination of the bristles 212 or 222 on their respective rings. Is increased to increase the contact area between the bristles 212 or 222 on each ring and the surface of the plate being cleaned.

Referring to FIG. 5, on two helical brushing members 21, 22, each ring is alternately arranged with respect to the rings of the helical frame 221, in which the rings of the helical frame 211 are very close to each other. The two ends a2, b2 of which form sections which are inclined to an inclination greater than the degree of inclination formed between the ends a1, b1 of each ring of the prior art, whereby bristles 212 on each ring Or 222 and the area of contact between the surface of the plate being cleaned is increased. Under these conditions, the rotation speed of the rotary shaft 10 rotates slowly in order to obtain a cleaning effect that can only be achieved under the high speed rotation speeds according to the prior art. For example, while the rotational speed in the prior art is 1000 rpm, two helical brushing members are used in the present invention, so that the same cleaning effect as achieved by the prior art is achieved by the present invention when 500 rpm is used.

In particular, by using the slow rotational speed of the present invention, the centrifugal force of the helical brush members 21, 22 which are slid over the rotary shaft 10 is slower, and the problem of vibration is reduced, so that The problem of scratches created on the surface is reduced.

Comparing the prior art with the present invention, if each of them has 100 times on its helical frame (s), the present invention alternates to produce bristles 212 or 222 on each ring that is inclined to a large degree of inclination. The helical brushing members 21 and 22 are assembled into a furnace, thereby increasing the cleaning effect obtained by the present invention having the same material as that of the prior art.

FIG. 6 shows another suitable embodiment of the present invention, in which the bristles 222 on the second helical brush member 22 increase the water suction force of the entire helical brush and obtain a sponge for cleaning purposes. sponge) (223).

The above techniques shown and described in the drawings are intended to illustrate suitable embodiments of the present invention, but are not intended to limit the scope of the present invention. Various equivalent changes and variations can be made of elements of the invention without departing from the scope of the invention, for example the brushing member can be replaced with a slightly different material and the amount of helical brushing member increased (3 or 4 or Moreover, it will be apparent to those skilled in the art that all such changes and changes are within the scope of the appended claims.

The present invention provides an improved rotary helical brush comprising a rotary shaft and first and second helical brushing members that slide across the rotary axis, whereby the rotation of the rotary axis moves by rotating the two helical brushing members.
