Background technology

General place to operate schools, be typically provided with a blackboard or blank, write font, the content of courses or explanation data for the teacher, useful font pen, blank pen are write on blank, but font pen, blank pen contain volatile toxic organic solvent, and be quite big for the human injury; Also useful chalk is write, but with chalk writing and teaching content, in a paragraph or time, will go wiping chalk institute content written with blackboard eraser, but the dust of chalk be cramping in the blackboard eraser bottom surface, blackboard eraser moves, the dust of chalk promptly drops, cause chalk dust to wave, spread everywhere everywhere, and make surrounding space be full of chalk dust, the healthy of instructor, learner especially teacher and child caused damage.

The utility model content

Use chalk on blackboard, to write in order to overcome existing place to operate schools, existence can produce dust when carrying out wiping with blackboard eraser, fly upward everywhere, contaminated environment, the shortcoming of harmful health, the utility model provides a kind of wireless primary and secondary blackboard eraser precipitron group, and this Dust collector for blackboard eraser group can suck the dust grain that is produced in the wiping process, dust can not flown upward everywhere, and can not damage other people healthy.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of wireless primary and secondary blackboard eraser precipitron group comprises an engine housing, an exhausting unit and a Wiper plate group; It is characterized in that described air exhauster assembling is located in the engine housing, installing Wiper plate group under this engine housing; This Wiper plate group is by a cleaning wiping cloth, a ventilative sponge piece, and glutinous in regular turn the splicing of a base plate and an air-permeable paper group forms; This cleaning wiping cloth is provided with many little pores, and the air-permeable paper group is a three-dimensional zigzag.

The beneficial effects of the utility model are that this Dust collector for blackboard eraser group can suck the dust grain that is produced in the wiping process, and dust can not flown upward everywhere, can not damage other people healthy.

The specific embodiment

See also Fig. 1 to shown in Figure 4, the utility model Dust collector for blackboard eraser plate 1 is to be made of an engine housing 10, an exhausting unit 20 and a Wiper plate group 30.

See also Fig. 2, shown in Figure 3, this engine housing 10 is divided into left and right casing 11,12, and this left and right casing 11,12 is symmetry each other, is provided with a battery tray 111 in the left casing 11, for battery 112 is set; The appearance of right casing 12 is provided with an opening 121, is used to install power switch 122.

Above-mentioned exhausting unit 20 comprises a motor 21 and extraction fan 22.

Above-mentioned Wiper plate group 30 is to be formed by a cleaning wiping cloth 31, one ventilative sponge piece 32, a base plate 33 and glutinous in regular turn the splicing of an air-permeable paper group 34; Wherein cleaning wiping cloth 31 is provided with little pore 311 many and that systematicness is arranged, ventilative sponge piece 32 be a kind of ventilative but sponge piece of dust grain thoroughly not, the plate face of base plate 33 is provided with a plurality of irregular holes 331, for ventilating air, air-permeable paper group 34 is to be converted into a kind of three-dimensional zigzag by an air-permeable paper 341, and frame is established a framework 342 around.

See also Fig. 2, shown in Figure 4, exhausting unit 20 is installed in the left casing 11, simultaneously battery 112 is loaded on battery tray 111, then,, again battery cover 13 is installed in the back segment place of left and right casing 11,12 right casing 12 corresponding left casing 11 installings; This cleaning wiping cloth 31 is sticked in the wherein one side of ventilative sponge piece 32, then both are sticked in the lump the wherein one side of base plate 33, and this air-permeable paper group 34 spliced in the another side of base plate 33, to constitute whole Wiper plate group 30, below these Wiper plate group 30 corresponding engine housings 10, install at last, and Dust collector for blackboard eraser machine 1 is finished in assembling.

See also Fig. 3 and shown in Figure 4, when Dust collector for blackboard eraser machine 1 is being done wiping when work, the user starts power switch 122 simultaneously, the exhausting unit 20 of this Dust collector for blackboard eraser machine 1 inside is done suction action simultaneously, the dust that in wiping process, is produced, owing to exhausting unit 20 is done suction action and is inhaled into, dust enters ventilative sponge piece 32 inside from the little pore 311 of Wiper plate group 30 cleaning wiping cloth 31, thicker particle then remains in ventilative sponge piece 32 inside in the dust, and remaining thinner dust can directly enter on the air-permeable paper 341 of air-permeable paper group 34 and accumulation.

See also shown in Figure 5, after 1 work of Dust collector for blackboard eraser machine is finished, the residual dust that is not inhaled into fully of surface meeting of its cleaning wiping cloth 31, and should ventilative sponge piece 32, air-permeable paper 341 also can accumulate dust, as long as this Dust collector for blackboard eraser machine 1 is moved in the standing groove 3 of blackboard eraser cleaner 2, this blackboard eraser cleaner 2 can leave and be sucked into blackboard eraser cleaner 2 inside with the dust suction that the surface of the cleaning wiping cloth 31 of Dust collector for blackboard eraser machine 1, ventilative sponge piece 32 and air-permeable paper 341 are accumulated in the mode of suction, to reach the effect that prevents dust from flying.
