Description
Technical field
The utility model relates to education instrument field, is specifically related to a kind of battery-driven dust absorption blackboard eraser, is applicable to the wiping of chalk in blackboard in teaching.
Background technology
In the learning life of daily campus, academics and students is in the time erasing the board, and a large amount of chalk dust particulates is forced, under brush, to spread in classroom, causes indoor dust particle to increase considerably, and has had a strong impact on IAQ.Dust particle is inhaled in body and can threatens teacher and student healthy.In the time that writing on the blackboard amount is larger, teacher and student need to take much time and muscle power erases the board, thereby have affected the learning time of students, bring a lot of inconvenience to studying and living.
Utility model content
The purpose of this utility model is to overcome existing technological deficiency, and a kind of battery-driven dust absorption blackboard eraser is provided, easy to use, little to physical impairment.
The purpose of this utility model can realize by following technical proposal:
A kind of battery-driven dust absorption blackboard eraser; comprise cleaning layer; also comprise filter course, dynamic absorption layer and protective layer; cleaning layer, filter course, dynamic absorption layer and protective layer are fitted fixing successively; on cleaning layer, be provided with dirt pad and air suction opening; filter course top side is provided with battery compartment; the bottom side of filter course is provided with chalk dust storage warehouse; between battery compartment and chalk dust storage warehouse, be provided with filter screen; the position of the corresponding filter screen of dynamic absorption layer is provided with electric fan; protective layer is provided with catch net, and electric fan is by the powered battery in battery compartment.
Dirt pad as above is dot matrix and distributes, and between the adjacent dirt pad of every row, air suction opening is set, and the dirt pad of adjacent lines is in staggered distribution.
Filter screen as above is the fine cloth material that Nomex or aperture are 10um-30um.
A kind of battery-driven dust absorption blackboard eraser, also comprises the switch for controlling electric fan.
The utility model compared with prior art has following beneficial effect:

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-5,
A kind of battery-driven dust absorption blackboard eraser, comprise cleaning layer 1, also comprise filter course 2, dynamic absorption layer 3 and protective layer 4, cleaning layer 1, filter course 2, dynamic absorption layer 3 and protective layer 4 are fitted fixing successively, on cleaning layer 1, be provided with dirt pad 101 and air suction opening 102, filter course 2 top sides are provided with battery compartment 201, the bottom side of filter course 2 is provided with chalk dust storage warehouse 203, between battery compartment 201 and chalk dust storage warehouse 203, be provided with filter screen 202, the position of the corresponding filter screen 202 of dynamic absorption layer 3 is provided with electric fan 301, protective layer 4 is provided with catch net 401, electric fan 301 is by the powered battery in battery compartment 201.Dirt pad 101 is dot matrix and distributes, and between the adjacent dirt pad 101 of every row, air suction opening 102 is set, and the dirt pad 101 of adjacent lines is in staggered distribution.Filter screen 202 is the fine cloth material that Nomex or aperture are 10um-30um.Also comprise the switch for controlling electric fan 301.
In use, dirt pad 101 is forced erasing chalk ash, and battery-powered electric fan 301 sucks dusty gas in filter course 2, and through the filtration of filter screen 202, chalk dust falls into chalk dust storage warehouse 203 and stores, and cleaned air after treatment enters atmosphere.Catch net 401 can effectively filter remaining chalk dust simultaneously, and chalk dust can not damaged human body.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
