Description

The rolling dedusting is wiped

The utility model belongs to a kind of dedusting to be wiped, and specifically a kind of rolling dedusting is wiped.

Ordinary blackboard eraser is wiped by rub body, ash and is formed, and rub body is a plank, and ash is wiped and is felt, and felt sticks on the plank.When using ordinary blackboard eraser to erase the board, dust from flying not only makes the people who erases the board expire the hand dust, and contaminated air, the serious harm academics and students's is healthy, so people have invented electrical dust-removing blackboard eraser, but, be not used widely because its cost height damages easily.

It is low that the purpose of this utility model provides a kind of cost, and can dedusting, prevent that the rolling dedusting of polluting indoor environment from wiping.

The purpose of this utility model is to realize like this, it is by rub body, ash is wiped and is formed, it is characterized in that it is to be made of the round brush that felt is being pasted on two surfaces that described ash is wiped, rub body is by box body, bonnet, dividing plate, movable floor constitutes, two round brush stretch out a part from two slots in box body front respectively, one end of roller brush shaft is inserted in the aperture on the box body, the other end inserts in the aperture of dividing plate, the rectangle hairbrush that bristle constitutes is housed in the middle of in the box body, this hairbrush is bolted between box body and the bonnet by one, the bristle of hairbrush contacts with the outer surface of round brush, both sides are stained with the elasticity brush in the box body, and elasticity is brushed available sponge and made, and the elasticity brush also contacts with the round brush outer surface, when round brush rolled, hairbrush and elasticity brush can be the brush of the dust on the round brush in box bodys.Dividing plate is inserted in the two interior side channels of box body, and movable floor can insert in box body groove bottom or extract out, forms dust storage chamber between dividing plate and the movable floor, two passages on the dividing plate, and dust is fallen into dust storage chamber from passage.When wiping was turned left in rolling dedusting wiping, the round brush on the left side rolled, and the round brush on the right does not rotate; When wiping toward the right, the round brush on the right rolls, and the round brush on the left side does not rotate; Round brush rolls and produces static, dirt absorption is brought in the box body, by hairbrush the passage on dividing plate under the brush of the dust on the round brush is fallen into dust storage chamber, dust under hairbrush is not brushed further by elasticity brush brush down, also fall into dust storage chamber, of long duration, can pour out dust by extraction activity bottom, then movable floor is inserted original position, can continue to use.

The utlity model has following advantage:

1. owing to the dust on the round brush is constantly brushed down by hairbrush and elasticity brush, so most of dust is fallen into dust storage chamber in the box, good dedusting effect.

2. owing to adopt rolling rather than stiff dough friction, shell is the ABS injection moulding, and is not fragile, long service life.

3. simple in structure, handling ease, cost is low.

4. not only can be used for erasing the board, but also can be used for wiping desktop deposition dust.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an A-A cutaway view of the present utility model.

Fig. 3 is a B-A cutaway view of the present utility model.

As shown in the figure, the round brush 2 and 3 that felt is being pasted on the surface stretches out a part respectively from the slot 9 and 10 in box body 1 front, round brush 2 and 3 a end is inserted in respectively in two apertures on the box body 1, the other end is inserted in two apertures on the dividing plate 7, two inboards of box body 1 are stained with sponge bar 4 and 5 respectively, sponge bar 4 and 5 outward flange contact with 3 outer garden with round brush 2 respectively, pressing the rectangle hairbrush 6 of two rectangular plate sandwich bristles in the box body 1 between centre and the bonnet 11, hairbrush 6 contacts with 3 outer gardens with two round brush 2, by a bolt 8 box body 1, hairbrush 6 and bonnet 11 are fixed together, dividing plate 7 is inserted in the groove of both sides in the box body 1, it is passage 12 and 13 that two holes are arranged on the dividing plate, movable floor 14 can insert in box body 1 groove bottom or extract out, forms dust storage chamber 15 between dividing plate 7 and the movable floor 14.Dust storage chamber is following during use, and when wiping toward round brush 2, round brush 2 rolls over there; When wiping toward round brush 3 over there, round brush 3 rolls, and when round brush 2 and 3 produces static because of rolling dirt is adsorbed, by hairbrush 6 with the brush of the dust on round brush 2 and 3 down, fall into dust storage chamber 15 by passage 12, the dust under hairbrush 6 is not brushed is further also fallen into dust storage chamber 15 by passage 13 down by sponge bar 4 and 5 brushes.
