Abstract
The utility model relates to a dust-absorbing blackboard eraser, which is provided with an upper and a lower arranged end cap and opens a casing for dust inlet at lower part of the front side. The upper part of the dust inlet of the casing is provided with a filter screen and the upper part of the filter screen is arranged with a generator arranged with fan blades. Both sides of the generator are provided with a middle air duct by a vertical baffle separating the casing and battery arrangement cavity at both sides. The end cap of the casing corresponding to the air duct is provided with an air outlet and the one side face of the casing is provided with a power switch. The casing is arranged with a vertical fixed erasing strip with frame at the front and definite space and the lower part is provided with an erasing body board for dust-absorbing openings corresponding to the dust inlet of the casing. The back of the erasing body board is provided with a socket body assembled with the casing socket. The utility model takes advantages of air current formed by a motor fan to absorb chalk powder dropped by the erasing strip of the blackboard eraser into the blackboard eraser by dust-absorbing openings and the dust is prevented retaining at the blackboard eraser via the filter screen. The utility model effectively solves the dust-blowing problem of the blackboard eraser while in use and has the characteristics of simple structure and convenient use.
Description
Technical field
The utility model relates to teaching aid, is a kind of dust absorption blackboard eraser that can avoid chalk dust to fly upward in use specifically.
Background technology
At present, at blackboard or similarly use chalk to write on the clipboard, in remaining, the main mode of primary school teaching, and the common tool of blackboard wiping remains on wiping board fixing rub body and the blackboard eraser that constitutes.When this type of blackboard eraser used, the chalk powder that wiping is got off can fly upward when falling everywhere, both the teacher and the healthy of student of listening to the teacher was worked the mischief, and influenced the environmental sanitation in classroom again.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of dust absorption blackboard eraser that can avoid chalk dust to fly upward in use is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of blackboard eraser that includes wiping board and rub body, its described wiping board by the upper and lower end cap of configuration and in front the bottom housing of offering the dust import constitute, horizontal above the dust import in housing have a screen pack, above screen pack, be provided with the motor that the fan leaf is installed, be provided with the vertical dividing plate of separating middle air channel of housing one-tenth and both sides battery placing chamber in the both sides of motor, be provided with air outlet with respect to position, middle air channel in last capping, be provided with power switch in a side of housing with respect to the battery lower end position; Its described rub body is made of the vertical wiping bar that is fixed at regular intervals on the wiping board body, be provided with in the front of rub body plate to enclose and wipe bar in interior frame, be provided with the grafting body that matches with the slot that is provided with on the housing leading flank at the back side of rub body plate, on the lower panel face of rub body plate with the corresponding air suction opening that is provided with of the dust import on the housing.
The utility model is designed to shell structure with wiping board, and assemble electric fan within it and stop the screen pack of dust, to suck in the blackboard eraser by the chalk powder that falls on the blackboard eraser rub body by air suction opening, solved the airborne dust problem when blackboard eraser uses effectively, and have characteristics simple in structure, easy to use.
Description of drawings
Fig. 1 is this dust absorption blackboard eraser structural representation;
Fig. 2 is the left cutaway view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
Provide as accompanying drawing, this dust absorption blackboard eraser has a rectangular housing 4, is equipped with upper end cover 1 and bottom end cover 12 through articulated axle respectively in the top and bottom of housing, offers the dust import in the front lower position of housing.Top position with respect to the dust import in housing is equipped with horizontal screen pack 11, above screen pack, be provided with the motor 6 that fan leaf 5 is installed, be provided with the vertical dividing plate 2 of battery 3 placing chambers of separating middle air channel of housing one-tenth and both sides at two side positions of motor.Be provided with the air outlet of forming by many elongated holes 15 in upper end cover 1 with respect to the position, air channel, be equipped with power switch 13 in position in a side of housing with respect to the battery lower end, dispose the front with housing frame 7 and the perpendicular at regular intervals fixedly rub body plate 10 of felt wiping bar 8 of putting are set, be provided with the vertical grafting body 14 of dove-tail form at the back side of rub body plate, utilize cooperating of the slot that is provided with on grafting body 14 and the housing leading flank, the rub body plate is inserted on the front of housing.On the lower panel face of rub body plate with housing on the corresponding air suction opening 9 that is provided with of dust import offered, this air suction opening is distributed in the both sides of respectively wiping bar, can be arranged to circular hole or slotted hole.
The lead that battery 3 of the present utility model, motor 6 and power switch 13 are configured is electrically connected.
When this dust absorption blackboard eraser used, the promotion power switch was connected circuit, the rotation of motor-driven fan leaf, and form by the air-flow of air channel, dust suction aperture to air outlet, this air-flow will be by the chalk powder of wiping the bar whereabouts by in the air suction opening inspiration housing.Enter chalk powder in the housing and be filtered net and stop and be trapped in the dust chamber of lower housing portion, thereby finish collection, avoid flying upward of chalk dust the chalk powder.After blackboard eraser uses a period of time, open the bottom end cover below the housing, the chalk powder that is stored in the housing can be cleared.
Wiping board of this blackboard eraser and rub body adopt split plug-in mounting assembling mode, are convenient to wipe change after bar weares and teares.
