Description
Technical field
The present invention relates to teaching aid technical fields, particularly a kind of dust suction environment friendly blackboard brush.
Background technology
Blackboard brush can cause the winged of chalk dust to alter, fly the powder altered for wiping and cleaning to blackboard in wiping process
Pen ash can cause different degrees of disease after entering the respiratory tract of human body, this is fatal for the teacher for engaging in educational work
Occupational disease.It is shown according to the whole nation and our province part data from investigation, with social progress and the quickening of social rhythm, teaching profession
Sick rate is in the trend risen year by year, and occupational disease is presented diversified direction and develops, and wherein pneumoconiosis caused by dust and various urgency is slow
Property breathing problem be main in Chinese occupational disease at present, endanger most serious and widest a kind of while same under dais
Also have different degrees of influence.It is a kind of rational in infrastructure to be badly in need of offer in such circumstances, it is easy to use, can efficiently dust suction it prevent
The blackboard brush of dirt.
The content of the invention
It is an object of the invention to solve above-mentioned technical problem, a kind of dust suction environment friendly blackboard brush is provided, with draught head
Principle collects chalk dust, greatly reduces harm of the chalk dust to educator and student.
In order to solve the above technical problems, present invention employs a kind of dust suction environment friendly blackboard brush, including brush body and arranged on described
The positive bristle of brush body, it is characterised in that：Perforation is equipped with sweep-up pipe in the brush body, and the suction end of the sweep-up pipe leads to bristle
One side, the exhaust end of the sweep-up pipe are connected with air bag, and the air bag inner wall is equipped with dust suction wet sponge, the air bag and the suction
Dirt pipe detachable-type sealed connects.
Further, in above-mentioned technical proposal, the sweep-up pipe is uniformly arranged on the bristle for more and suction end
One side.
Further, in above-mentioned technical proposal, a diameter of 5mm of the sweep-up pipe.
Further, in above-mentioned technical proposal, the air bag for easily recover shape rubber material, the thickness of the air bag
For 1-3mm.
Advantageous effect possessed by the present invention：Due to being equipped with sweep-up pipe in brush body, the exhaust end of sweep-up pipe is equipped with air bag,
Air bag can generate certain inspiratory effects in the case where squeezing it, during sassafras blackboard, first squeeze a lower gasbag, just can
The chalk dust generated during sassafras blackboard is sucked simultaneously, and due to being equipped with dust suction wet sponge in air bag, chalk dust is viscous after being inhaled into
Invest on dust suction wet sponge, afterwards can manipulation balloon again, carry out dust suction action, the design is simple in structure, easily operated, has
Good practical value.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Wherein：Brush body 1；Bristle 2；Sweep-up pipe 3；Air bag 4；Dust suction wet sponge 5.
Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention provides a kind of dust suction environment friendly blackboard brush, including brush body 1 and arranged on 1 positive bristle of brush body
2, wherein, it is penetrated through in brush body 1 and is equipped with sweep-up pipe 3, the suction end of sweep-up pipe 3 leads to 2 one side of bristle, and the exhaust end of sweep-up pipe 3 connects
Air bag 4 is connected to, 4 inner wall of air bag is equipped with dust suction wet sponge 5, and air bag 4 is connected with 3 detachable-type sealed of sweep-up pipe.Sweep-up pipe 3 is 5
Root and suction end are uniformly arranged on the one side of bristle 2, a diameter of 5mm of sweep-up pipe 3, and air bag 4 is the easy rubber material for recovering shape
Matter, the thickness of air bag 4 is 1mm.
Due to being equipped with sweep-up pipe in the brush body 1, the exhaust end of sweep-up pipe is equipped with air bag 4, and air bag 4 is squeezing it
In the case of can generate certain inspiratory effects, during sassafras blackboard, first squeeze a lower gasbag 4, just can suck sassafras blackboard process simultaneously
The chalk dust of middle generation, due to being equipped with dust suction wet sponge 5 in air bag 4, chalk dust is adhered to dust suction wet sponge 5 after being inhaled into
On, afterwards can manipulation balloon 4 again, carry out dust suction action, the design is simple in structure, easily operated, has practical valency well
Value.
The present invention specification and drawings be considered as it is illustrative and not restrictive, on the basis of the present invention, ability
Field technique personnel are not required performing creative labour that can be made to some of technical characteristics according to disclosed technology contents
Some are replaced and deformation, within the scope of the present invention.
