Abstract
The utility model discloses a dust suction blackboard eraser which is composed of a hair felt 2, a wiping plate 3, a dust suction chamber 4, a wind wheel 5, a direct current motor 8, a dust storage chamber 12 and a dust storage bag 13. When the utility model is used, after a switch 7 is switched on with a circuit, the direct current motor 8 can drive the wind wheel 5 to rotate, and wiped dust enters the dust storage bag 13 through air suction holes 2 on the wiping plate 3, the wind wheel 5 in the dust suction chamber 4 and a dust discharge hole 10 between the dust suction chamber 4 and the dust storage chamber 12. After the dust storage bag 13 is filled with dust, the dust can be conveniently cleared from a dust removal port. Thus, the condition that the dust flies up can not be generated and the utility model effectively protects the health of teachers and students.
Description
The utility model relates to a kind of dust absorption blackboard eraser, belongs to the realia field.

The purpose of this utility model just is to provide a kind of blackboard eraser that can dust suction.
For achieving the above object, the utility model dust absorption blackboard eraser is by felt, wiping board, dust suction chamber, wind wheel, direct current generator, dust-storage chamber, storage dirt bag is formed, felt is fixed on the wiping board, wiping board has air suction opening and leads to dust suction chamber, wind wheel is positioned at dust suction chamber, the wind wheel center faces the air suction opening center, dust suction chamber has dust exhausting hole and leads to dust-storage chamber, the outlet that the sack of the storage dirt bag in the dust-storage chamber entangles dust exhausting hole, also be provided with dedusting mouth to be opened/closed on the storage dirt bag, have passage on the sidewall of dust-storage chamber, also be provided with battery compartment in dust-storage chamber, the battery in the battery compartment is electrically connected with switch and direct current generator.
After adopting such structure, when erasing the board with the utility model blackboard eraser, the dust that falls down is sucked by wind wheel through air suction opening, enters storage dirt bag through dust exhausting hole, thereby the situation of dust from flying can not take place, and has protected effectively that teachers and students' is healthy.
Below in conjunction with the drawings and specific embodiments the utility model dust absorption blackboard eraser is described in further detail.
Fig. 1 is that the master of the utility model dust absorption blackboard eraser looks cutaway view.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Fig. 1 to Fig. 3 has provided the specific embodiment of the utility model dust absorption blackboard eraser, it is by felt 1, wiping board 3, dust suction chamber 4, wind wheel 5, direct current generator 8, dust-storage chamber 12, storage dirt bag 13 is formed, wiping board 3 has indent, felt 1 is fixed on indent one side of wiping board 3 and protrudes in the surface of wiping board 3 concave side, the opposite side of wiping board 3 has air suction opening 2 and leads to the dust suction chamber 4 that is connected with wiping board 3, be provided with wind wheel 5 in the dust suction chamber 4, wind wheel 5 centers face air suction opening 2 centers, dust suction chamber 4 has dust exhausting hole 10 and leads to dust-storage chamber 12, the one side that dust exhausting hole 10 is positioned at dust-storage chamber 12 is provided with non-return valve 11, the outlet that the sack of the storage dirt bag 13 in the dust-storage chamber 12 entangles dust exhausting hole 10, also be provided with dedusting mouth to be opened/closed on the storage dirt bag 13, have passage 6 on the sidewall of dust-storage chamber 12, in dust-storage chamber 12, also be provided with battery compartment 9, battery in the battery compartment 9 is electrically connected with switch 7 and direct current generator 8, for wind wheel 5 provides power.In this specific embodiment, wiping board 3 is provided with two felts 1, certainly in fact also can adopt one or more, have two groups of air suction openings 2 on the wiping board 3, therefore wind wheel 5 and direct current generator 8 also respectively have two, and in dust suction chamber 4, need to be provided with dividing plate dust suction chamber 4 is divided into two parts, every part has one group of air suction opening 2, a wind wheel 5, dividing plate also is divided into two parts to dust exhausting hole 10 and these two parts is communicated with two parts of dust suction chamber 4 respectively simultaneously, but what the non-return valve 11 that entangles the exit of dust exhausting hole 10 adopted is the blind window form of folding, the switching mode of the dedusting mouth on the storage dirt bag 13 can adopt zip mode, adhesive type, the form that the form that plug formula etc. easily open and close or several mode combine, what provide in this specific embodiment diagram is the plug formula, it is that the dedusting mouth that will store up dirt bag 13 is connected on corresponding tapping on dust-storage chamber's 12 sidewalls, and plug 14 is just in time blocked this perforate.
The utility model dust absorption blackboard eraser in use; after switch 7 is connected circuit; direct current generator 8 can drive wind wheel 5 rotations; dust under wiping is sucked storage dirt bag 13; behind the storage dirt bag 13 long-pending full dust; can be easily remove, thereby the situation of dust from flying can not take place, protected effectively that teachers and students' is healthy by the dedusting mouth.
