A kind of capsule dust self-sucking formula blackboard eraser, including handle, capsule seat, sponge, capsule body and hair rub, exhaust pipe and towel interlayer.It is characterized in that：Capsule seat is set as cuboid or round, capsule seat lower, outer perimeter is equipped with annular table, the capsule body of cuboid or round is cased in annular table, the reeded sponge in the inc middle part of hole is equipped in capsule body, it is equipped with the animal hair rub for arrangement of uniformly gathering in the bottom of capsule body, it is equipped with miniature dust absorption hole between the gap of hair rub, is equipped with arcuate hand grip and towel interlayer in the middle part of upper top, exhaust pipe is equipped between towel interlayer and sponge periphery.In the inc micropore for the dust inspiration sponge or elastoplastic foam that animal hair rub generation electrostatic is sucked the present invention, chalk dust is made not fly upward, it is free from environmental pollution, achieve the purpose that protect teacher and student physically and mentally healthy.
Description
Technical field
The present invention relates to a kind of tool used in teaching field, specifically a kind of anti-dust pollution, protection teacher and
Raw physically and mentally healthy capsule dust self-sucking formula blackboard eraser.
Background technology
There are many patent of application blackboard eraser at present, are mainly designed with Chalk-dust suction, have electronic, there is hand-push rolling
Formula, also other modes, some structures are too complicated to be not convenient to use, and some is too simple, and it is poor to inhale powder effect.In order to preferably protect
The physical and mental health of teacher and student are protected, the application goes out one using the suction capacity of capsule and the electrostatic precipitation capability study of animal wool
The blackboard eraser of kind brand new, it is simple in structure, it is easy to use, pick-up performance is 95% or more.
Invention content
The object of the present invention is to provide a kind of capsule dust self-sucking formula blackboard eraser, overcomes and lacked existing for above-mentioned prior art
It falls into.
The technical scheme is that be accomplished by the following way：
The present invention includes:Handle, capsule seat, sponge, capsule body, hair rub, exhaust pipe and towel interlayer.It is characterized in that：
The capsule seat is set as cuboid or round, and capsule seat lower, outer perimeter is equipped with annular table, be cased in annular table cuboid or
The capsule body of round is equipped with the reeded sponge in the inc middle part of hole in capsule body, is equipped in the bottom of capsule body
The uniformly animal hair rub of densely covered arrangement is equipped with miniature dust absorption hole between the gap of hair rub, arcuate hand grip and hair is equipped in the middle part of upper top
Towel interlayer is equipped with exhaust pipe between towel interlayer and sponge periphery.
Periphery is equipped with exhaust duct aperture in the middle part of capsule seat in above-mentioned capsule dust self-sucking formula blackboard eraser.
Capsule body in above-mentioned capsule dust self-sucking formula blackboard eraser is equipped with undergauge platform in open end, and capsule integrally uses silica gel
Compression molding, hair rub mosaic bonding is in capsule body bottom surface.
Cavernous body in above-mentioned capsule dust self-sucking formula blackboard eraser is set as cuboid or round, material or uses plastic blister
Foam.
The exhaust velocity of exhaust pipe in above-mentioned capsule dust self-sucking formula blackboard eraser is less than the air-breathing speed of capsule body.
The operation principle of the present invention：
The present invention generates the dust removal ability of electrostatic by being applied to capsule using the suction capacity of capsule and the friction of animal wool
Pressure gas releases stress the principle of air-breathing, the dust inspiration sponge that animal hair rub generation electrostatic is sucked or elastoplastic bubble
In the micropore of foam, chalk dust is made not fly upward, it is free from environmental pollution, achieve the purpose that the physical and mental health for protecting teacher and student.
Compared with the prior art the present invention has the following advantages：
1. the dust removal ability for being generated electrostatic using the suction capacity of capsule and the friction of animal wool is arranged by pressing to capsule
Gas releases stress the principle of air-breathing, by the animal hair rub dust inspiration sponge that is sucked of generation electrostatic or elastoplastic foam
In hole, chalk dust is made not fly upward, free from environmental pollution
2. simple in structure, rationally distributed
3. it is easy to use, as long as handle holds capsule seat, erase the board above and below.Gas when pressure erases the board in capsule
Outer row erases the board one when acting stopping, in the gap for the dust inspiration sponge that animal hair rub generation electrostatic is sucked
4. towel interlayer can inhale the sweat of the palm of the hand and filter dust, moreover it is possible to hinder the inspiratory capacity of exhaust pipe, improve capsule
The dust removal ability of body.
Description of the drawings
The structural schematic diagram of Fig. 1-present invention
In figure, 1- handles, 2- capsules seat, 3- sponges, 4- capsule bodies, 5- hair rubs, 6- exhaust pipes, 7- towel interlayers.
Specific implementation mode
Further to disclose technical scheme of the present invention, elaborated with reference to the accompanying drawings of the specification by embodiment：
The present invention includes：Handle 1, capsule seat 2, sponge 3, capsule body 4 and hair rub 5, exhaust pipe 6 and towel interlayer 7.It is described
Capsule seat 2 is set as cuboid or round, and 2 lower, outer perimeter of capsule seat is equipped with annular table, cuboid or circle are cased in annular table
The capsule body 4 of body is equipped with the reeded sponge 3 in the inc middle part of hole or elastoplastic foam, in glue in capsule body 4
Animal hair rub 5 of the bottom of utricule 4 equipped with arrangement of uniformly gathering is equipped with miniature dust absorption hole, upper top middle part between the gap of hair rub 5
Equipped with arcuate hand grip 1 and towel interlayer 7, exhaust pipe 6 is equipped between 3 periphery of towel interlayer 7 and sponge.
In the application present invention, as long as holding capsule seat 2 by handle 1, erase the board above and below.When pressure erases the board
For gas in capsule body 4 by being arranged outside exhaust pipe 6, release when acting stopping that erasing the board one generates the pressure of capsule body simultaneously
Suction, in the inc micropore of dust inspiration sponge 3 or elastoplastic foam that the generation electrostatic of hair rub 5 is sucked, so
Reciprocating action until cleaning off a blackboard.Micropore when due to pressure on 2 bottom surface of capsule seat is in the case where compressing the extruding with hair rub
Gas can only be discharged from exhaust pipe in closed state, capsule body, and the capacity of exhaust pipe 6 is small in addition, and capsule body 4 will not be unexpected
Deformation, keeps the certain dynamics to erase the board, to obtain the good result to erase the board.In 4 air-breathing dust suction of capsule body towel every
Layer 7 can inhale the sweat of the palm of the hand and filter dust, moreover it is possible to hinder the inspiratory capacity of exhaust pipe, improve the dust removal ability of capsule body 4.
When capsule dust self-sucking formula blackboard eraser is with a period of time, capsule body 4 is unloaded, is rushed capsule seat 2, capsule body 4 and sponge 3 with water
Wash clean.It dries and assembles, wait for that next time is used again.
