Description

The roller blackboard eraser

Technical field

The utility model relates to a kind of culture, education and public health articles for use, specifically relates to be used for the roller cleaning dust remover of blackboard wiping dust.

Background technology

The device of being sold in the market that is used for the wiping of blackboard dust generally is a blackboard eraser, but the i.e. fixing material of viscous dust such as suede cotton on the plate face; Low, the dust from flying of efficient influenced health when its shortcoming was wiping.In order to address this problem, the someone has designed the dustproof wiping blackboard structure, as application number be 96245483, the applying date is on November 5th, 1996, denomination of invention is the patent application of " dust-proof blackboard eraser ", it is to be made of plank, felt and dust cover.The height of dust cover equates that with the height of felt it can touch blackboard simultaneously with felt, and the chalk powder of being wiped off by felt when erasing the board drops in the dust cover, thereby prevents dust pollution.Though said structure is comparatively simple, and have certain dustproof effect, result of use is still not very good.

Someone adopts the blackboard eraser of roller, as application number is 97223353, the applying date is on May 31st, 1997, denomination of invention is the utility application of " roller dust-removing blackboard eraser ", it comprises the felt of dedusting, the rectangular body of the shell body of blackboard eraser, its upper surface is the belt body that opening part reveals dedusting, this belt body supports to triangle by the axis of rolling of at least ten spacing distances with it in housing, its maximum----angle is 90 °-120 °, the width of belt body is identical with the width of the upper shed of housing, the bottom surface of belt body is the flexible plastic body, be bonded with a fiber crops or felt on it, reveal on its flexible plastic body both sides teeth limit and the interlock mutually of microscler tooth handle; Its underpart contacts with the curette that shakes, and the lower end of the curette junction that shakes has the semicircle bracing frame of an elasticity that one software funnel is arranged in the lower end of bracing frame, and the triangle link stopper is located at microscler tooth handle top, and envelope has backplate above teeth limit, belt body both sides.Though the blackboard eraser result of use of said structure improves, structure is also comparatively complicated, is not very convenient during use, and service efficiency also remains further to be improved.

Summary of the invention

The purpose of this utility model is to provide a kind of easy to use, high roller blackboard eraser simple in structure of efficiency of dust collection.

For achieving the above object, the utility model is to adopt following scheme to realize: this roller blackboard eraser comprises a housing and the roller, the cylinder of external belt felt, the cleaning brush wheel that are located in the housing, be divided into wiping chamber and dust storage chamber before and after in the housing, the two is provided with slanting baffle and dust inlet, it is indoor that roller, cylinder, cleaning brush wheel all are arranged on the wiping of housing, housing bottom has the hole, roller, cylinder place opening part, roller and cylinder are in transmission connection, and cleaning brush wheel is fixed on cylinder top and contacts.

As the further improvement of such scheme, the housing front portion that is positioned at cylinder is provided with pulley, and this pulley bottom becomes a horizontal plane with idler wheel bottom.

Being positioned at behind the cylinder of described housing also is provided with a baffle plate between bottom and dust storage chamber, is provided with a breach between the separation baffles of this baffle plate and wiping chamber and dust storage chamber and constitutes dust inlet.

The dust storage chamber rear portion of described housing is provided with movable dockboard, and this dockboard one end and housing are hinged, other end active buckle.

Described housing top also is provided with handle.

Further improvement as such scheme also can be provided with motor in the described housing, and motor and roller are in transmission connection.

The wheel footpath of described roller is greater than cylinder drive footpath.

Adopt the beneficial effect of said structure to be, owing to adopted the rotation of cylinder, behind the felt wiping dust on it, felt is brushed the dust on it fall through the cleaning wheel brush again, enter dust storage chamber from dust inlet, felt after clean enters next step wipe process again, so repeatedly, easy to use, efficiency of dust collection is high, simple in structure; The rolling of cylinder drives by roller, and roller rolls on the blackboard desktop, because it takes turns the footpath greater than cylinder drive footpath, makes the rolling rotating speed of the rolling rotating speed of cylinder greater than roller, thereby can realize cylinder felt wiping function; No matter the roller motion is for advancing or moving back (last or following), the cleaning wheel brush all can make the cleaning wheel brush be the felt dedusting on the cylinder with relatively rotating of cylinder just, roller all drives cylinder and rolls in the other direction, all make the felt on the cylinder effectively also clean the blackboard desktop fast, can reach best cleaning effect of the present utility model, help improving indoor environmental hygiene.

Description of drawings

Be described further below in conjunction with drawings and Examples;

Fig. 1 is the utility model structural representation;

Fig. 2 is a roller running part structural representation of the present utility model.

The specific embodiment

As Fig. 1, shown in Figure 2, this roller blackboard eraser of the present utility model comprises a housing (1) and is located at roller (5) in the housing (1), the cylinder (4) of external belt felt (3), cleaning brush wheel (12), handle (10), be divided into wiping chamber (11) and dust storage chamber (8) before and after in the housing (1), the two is provided with slanting baffle (7) and dust inlet, roller (5), cylinder (4), cleaning brush wheel (12) all is arranged in the wiping chamber (8) of housing, housing bottom has the hole, roller (5), cylinder (4) places opening part, they are fixed by axle and housing, roller (5) is respectively established one in two bottom sides, roller (5) is in transmission connection with cylinder (4) interlock, cleaning brush wheel (12) is fixed on cylinder (4) top and contacts, the housing front part sides that is positioned at cylinder (4) respectively is provided with a pulley (2), also can establish a pulley therebetween, this pulley (2) bottom becomes a horizontal plane with roller (5) bottom; Being positioned at behind the cylinder of described housing (1) also is provided with a baffle plate (6) between bottom and dust storage chamber (8), is provided with a breach between the separation slanting baffle (7) of this baffle plate (6) and wiping chamber and dust storage chamber and constitutes dust inlet.The dust storage chamber of described housing (8) rear portion is provided with movable dockboard (9), and this dockboard (9) lower end and housing are hinged, upper end and housing active buckle.
