The dust box back is fixedly connected with hairbrush, and the housing top end is fixedly connected with handle, and the interior of shell is slidably connected
There is dust collection drawer, is fixedly connected with strainer on the inside of the dust collection drawer, the dust collection drawer bottom end is fixedly connected with partition, described
Partition offers aspirating hole, and the partition bottom end is fixedly connected with motor, and the electric machine main shaft end is fixedly connected with flabellum, institute
It states case nose face bottom and offers exhaustion plate, switch, shell (4) the rear end face outside are offered on the left of the shell lower end
It is fixedly connected with sliding block, slidably connects slide rail on the outside of the sliding block.
Preferably, the width of the sweep-up pipe is 4cm, and sweep-up pipe triangular shape is arranged.
Preferably, the strainer is located above partition.
Preferably, distance of the slide rail away from blackboard is 15cm.
Preferably, distance of the flabellum away from lower section exhaustion plate is 10cm.
Compared with prior art, the utility model has the beneficial effects that
1, in the utility model, by the sweep-up pipe of setting, the chalk dust that hairbrush wipes can be passed through into interior outer space
Draught head inspiration disposal box can mitigate chalk dust and drift aerial, soakage of the reduction teachers and students to chalk dust, reduction air dirt
Dye is advantageous to the physical and mental health of teachers and students；
2, in the utility model, driving handle is only needed, is made on dust-extraction unit when wiping blackboard by the handle of setting
Hairbrush and blackboard generate friction, and then wipe hairbrush to blackboard, make convenient and strength-saving, the operation side when wiping blackboard
Just；
3, in the utility model, by the sliding block of setting, be slidably connected with slide rail, make dust-extraction unit always with blackboard
It is slidably connected together, wiping is more laborsaving, is easy to use when wiping blackboard, not will cause the feelings that blackboard eraser is often lost
Condition.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:
The top end face rear side of a kind of classroom blackboard dust-extraction unit, the shell 4 is fixedly connected with dust-extraction unit 2, described
Dust-extraction unit 2 includes disposal box 201, hairbrush 202 and sweep-up pipe 203, and 201 two sides of disposal box are fixedly connected with sweep-up pipe
203, the sweep-up pipe 203 of setting, the chalk dust that hairbrush 202 can be wiped passes through inner air and outer air pressure difference inspiration disposal box,
Chalk dust can be mitigated and drift aerial, soakage of the reduction teachers and students to chalk dust, reduction air pollution is strong to the body and mind of teachers and students
Kang Youli, 201 rear end of disposal box are fixedly connected with hairbrush 202, and 4 top of shell is fixedly connected with handle 10, setting
Handle 10 only need driving handle 10 when wiping blackboard 1, so that hairbrush 202 on dust-extraction unit 2 and blackboard 1 is generated friction,
And then wipe hairbrush 202 to blackboard 1, make, easy to operate, the shell 4 inside cunning convenient and strength-saving when wiping blackboard 1
It is dynamic to be connected with dust collection drawer 8, strainer 7 is fixedly connected on the inside of the dust collection drawer 8,8 bottom end of dust collection drawer is fixedly connected
There is partition 11, the partition 11 offers aspirating hole a, and 11 bottom end of partition is fixedly connected with motor 6,6 main shaft of motor
End is fixedly connected with flabellum 13, and 4 bottom end of shell offers exhaustion plate 12, and the 4 front end face bottom of shell offers out
3 are closed, 4 front/rear end of shell is fixedly connected with sliding block 9, and the sliding block 9 of setting is slidably connected with slide rail 5, fills dedusting
It sets 2 to be slidably connected with blackboard 1 always together, wiping is more laborsaving, is easy to use when wiping blackboard 1, not will cause blackboard
It wipes the case where often losing, slidably connects slide rail 5 on the outside of the sliding block 9.
The width of the sweep-up pipe 203 is 4cm, and 203 triangular shape of sweep-up pipe is arranged, in the mistake for carrying out wiping dust suction
Cheng Zhong, dust suction area is big, reduces the friction of sweep-up pipe 203 and blackboard 1, can more effectively work, the strainer 7 is located at partition 11
Top can will reduce being scattered for chalk dust on chalk dust centralized collection and strainer 7, the slide rail 5 away from blackboard 1 away from
From for 15cm, have distance between slide rail 5 and blackboard 1, can preferably be slided, work more labor-saving, the flabellum away from
The distance of lower section exhaustion plate is 10cm, can be preferably aerated.
Workflow: sliding block 9 is slidably connected with slide rail 5, and lower switch 3, electricity are pressed in the electric connection of switch 3 and motor 6
Machine 6 is powered, and driving handle 10 slides sliding block 9 on slide rail, in sliding process, passes through the rubbing to blackboard 1 of hairbrush 202
Wiping effect, dust eraser is fallen, by the air-extraction function of motor 6, scraping chalk dust is absorbed into come right by sweep-up pipe 203
Blackboard 1 is wiped.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
