Embodiment

With reference to the accompanying drawings and examples, embodiment of the present utility model is further described.Implement below Example is only used for clearly illustrating the technical solution of the utility model, and protection model of the present utility model can not be limited with this Enclose.

A kind of automatic dust-absorption eraser in 1~Fig. 3 of reference picture, the embodiment of the utility model one is in vertical direction from upper Blackboard eraser body 1, dividing plate 2, dust storage chamber 3 and dust mouth 4 are set gradually under, the dividing plate 2 is installed in the side away from blackboard Flat board 41 is set at handle 21, the dust mouth 4, connected between the flat board 41 and the dust storage chamber 3 for buckle-type；

Round brush 11 and dust blowing piece 12 and dust piece 13 below the round brush, institute are set in the blackboard eraser body 1 Stating round brush 11 includes roller 14 and dust suction wiper 15, and the dust suction wiper 15 is adhered on the outer surface of the roller 14, described The both sides of roller 14 in axial direction are hinged with the blackboard eraser body 1；

Each round brush 11 corresponds to respective dust blowing piece 12 and dust piece 13, and the dust blowing piece 12 is vertical plate, described to scrape The blackboard eraser body 1 is fixed in one end of dirt piece 12, and the other end of the dust blowing piece 12 is contacted with the dust suction wiper 15, institute Dust piece 13 is stated for hang plate, the quantity of the dust piece 13 is 2, is symmetricly set in the both sides of the round brush 11, the collection The blackboard eraser body 1 is fixed in one end of dirt piece 13, and the other end of the dust piece 13 is contacted with the dust suction wiper 15, The dust piece 13 and the tangential direction that the contact direction of the round brush 11 is the wall of round brush 11；The dust piece 13 and institute State and dust passage 16 narrow in the middle of two head breadths is formed between dust blowing piece 12, the dust passage 16 is communicated to the dust storage chamber 3； Wherein, the dust blowing piece 12 and dust piece 13 are one kind in steel plate, hard plastic board.

The operation principle of automatic dust-absorption eraser described in the utility model is as follows：

Under plumbness, dividing plate 2 is pulled out by handle 21 before being wiped so that dust passage 16 and dust Room 3 is connected, and when round brush 11 is contacted with blackboard, frictional force drives roller 14 between the two is rolled, and adheres to roller 14 The dust suction wiper 15 on surface is wiped to blackboard, and dust blowing piece 12 strikes off the chalk dust on round brush 2, and positioned at round brush, about 2 both sides 13 pairs of chalk dusts scraped of dust piece be collected, prevent chalk dust from repeating between each round brush to inhale caused by dispersing after being scraped Dirt, while preventing chalk dust from occurring reuniting and wall sticking phenomenon, the chalk dust of each round brush is because gravity is via respective dust Passage 16 falls directly into dust storage chamber 3, after blackboard-cleaning is clean, opens the flat board 41 being connected with the buckle-type of dust storage chamber 3, will The chalk dust of collection is poured out by dust mouth 4, so as to complete the work of periodic cleaning, this can greatly improve operating efficiency, and And can continuous Reusability blackboard eraser, it is convenient and swift, extend the service life of blackboard eraser.

Specific embodiment of the utility model is described in detail above, but it is only used as example, the utility model It is not restricted to particular embodiments described above.To those skilled in the art, it is any that the practicality is equal Modifications and substitutions are also all among category of the present utility model.Therefore, the institute in the case where not departing from spirit and scope of the present utility model The impartial conversion and modification of work, should all cover in the range of the utility model.
