Description
Technical field
The present invention relates to realia technical field, specially a kind of classroom blackboard dust-extraction unit.
Background technology
Blackboard eraser is a kind of tool for being wiped to blackboard, and chalk dust can drift in the air when wiping, the present invention
Wiping using dust-extraction unit and dust-absorbing function, using the air extracting function of motor, friction when mitigating mobile using rail plate
Power creates good teaching environment, therefore, growing to a kind of demand of classroom blackboard dust-extraction unit.
The general manufacture craft of most of blackboard erasers is simple currently on the market, is easily damaged, and can not thoroughly remove on blackboard
Chalk dust, chalk dust can drift in the air when wiping, and teachers and students can be harmful to body because of air of the breathing with chalk dust,
Can be relatively elaborate when blackboard eraser is for blackboard wiping, it can also descend slowly and lightly perhaps with causing away from the excessively close place of blackboard because of station
More chalk dusts are easily lost and damage, and loss can cause class hour inconvenient, therefore, propose regarding to the issue above a kind of
Classroom blackboard dust-extraction unit.
Invention content
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of classroom blackboard dust-extraction unit
Problem.
To achieve the above object, the present invention provides the following technical solutions：
The top end face rear side of a kind of classroom blackboard dust-extraction unit, including blackboard and shell, the shell is fixedly connected with dedusting
Device, the dust-extraction unit include disposal box, hairbrush and sweep-up pipe, and the disposal box both sides are fixedly connected with sweep-up pipe, described
Dust box back is fixedly connected with hairbrush, and the housing top end is fixedly connected with handle, and the enclosure slidably connects collection
Dirt drawer, the dust collection drawer inside are fixedly connected with strainer, and the dust collection drawer bottom end is fixedly connected with partition board, the partition board
Aspirating hole is offered, the partition board bottom end is fixedly connected with motor, and the electric machine main shaft end is fixedly connected with flabellum, described outer
Shell front end face bottom offers exhaustion plate, and switch, the shell are offered on the left of the shell lower end（4）It is fixed on the outside of rear end face
It is connected with sliding block, rail plate is slidably connected 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 board.
Preferably, distance of the rail plate away from blackboard is 15cm.
Preferably, distance of the flabellum away from lower section exhaustion plate is 10cm.
Compared with prior art, the beneficial effects of the invention are as follows：
1, in the present invention, by the sweep-up pipe of setting, the chalk dust that hairbrush wipes can be inhaled by inner air and outer air pressure difference
Into disposal box, chalk dust can be mitigated and drift aerial, soakage of the teachers and students to chalk dust is reduced, air pollution is reduced, to teacher
Raw physical and mental health is advantageous；
2, in the present invention, driving handle is only needed in blackboard wiping by the handle of setting, make hairbrush on dust-extraction unit with
Blackboard generates friction, and then hairbrush is made to wipe blackboard, make it is convenient and strength-saving in blackboard wiping, it is easy to operate；
3, it in the present invention, by the sliding block of setting, is slidably connected with rail plate, dust-extraction unit is made to be slidably connected always with blackboard
Together, more laborsaving, will not cause blackboard eraser often lose the case where easy to use in blackboard wiping is wiped.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the present invention 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, the dedusting
Device 2 includes disposal box 201, hairbrush 202 and sweep-up pipe 203, and 201 both sides of the disposal box are fixedly connected with sweep-up pipe 203, if
The sweep-up pipe 203 set, the chalk dust that can wipe hairbrush 202 can be subtracted by inner air and outer air pressure difference inspiration disposal box
Gently chalk dust drifts aerial, reduces soakage of the teachers and students to chalk dust, reduces air pollution, have to the physical and mental health of teachers and students
Profit, 201 rear end of the disposal box are fixedly connected with hairbrush 202, and 4 top of the shell is fixedly connected with handle 10, the hand of setting
Handle 10 only needs driving handle 10 in blackboard wiping 1, so that the hairbrush 202 on dust-extraction unit 2 is generated friction with blackboard 1, in turn
So that hairbrush 202 is wiped blackboard 1, makes, easy to operate, the shell 4 internal slide company convenient and strength-saving in blackboard wiping 1
Be connected to dust collection drawer 8,8 inside of the dust collection drawer is fixedly connected with strainer 7,8 bottom end of the dust collection drawer be fixedly connected with every
Plate 11, the partition board 11 offer aspirating hole a, and 11 bottom end of the partition board is fixedly connected with motor 6,6 main shaft end of the motor
It is fixedly connected with flabellum 13,4 bottom end of the shell offers exhaustion plate 12, and 4 front end face bottom of the shell offers switch 3,
4 front/rear end of the shell is fixedly connected with sliding block 9, and the sliding block 9 of setting is slidably connected with rail plate 5, makes dust-extraction unit 2
Always it is slidably connected with blackboard 1 together, wiping is more laborsaving, easy to use in blackboard wiping 1, blackboard eraser will not be caused to pass through
The case where often losing, 9 outside of the sliding block slidably connect rail plate 5.
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 board 11
Top can will reduce being scattered for chalk dust on chalk dust centralized collection and strainer 7, the rail plate 5 away from blackboard 1 away from
From for 15cm, have distance between rail plate 5 and blackboard 1, can preferably be slided, work is more effortless, 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 rail plate 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 makes sliding block 9 be slided on rail plate, in sliding process, passes through the rubbing to blackboard 1 of hairbrush 202
Wiping acts on, and 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.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
