Description
Technical field
The utility model relates to teaching field, in particular to a kind of mathematical education blackboard eraser.
Background technique
With advances in technology and the raising to teaching request, the environment of education activities are also required to improve.Although currently, I
School of state is commonly used multimedia teaching, but for Mathematics Curriculum, in order to help student with deep impression, for some logics
Operation is there is still a need for deriving step by step, this process often write on blackboard by upper hand-held chalk, when erasing the board,
Chalk dust can dance in the air all over the sky, be inhaled into the internal of people, or even cause nose, pharynx, throat uncomfortable, drastically influence the health of human body.
Utility model content
In view of the above drawbacks of the prior art, the technical problem to be solved by the utility model is to provide a kind of religions of mathematics
Blackboard eraser.
To achieve the above object, a kind of mathematical education blackboard eraser, including blackboard eraser body, the blackboard eraser body are provided
Rear end face is connected with handle front end face and is connected with cleaning cotton, and the blackboard eraser body front end face is around the oriented lower recess of cleaning cotton
First stores up ash-pit, and two sides are horizontally disposed above and below the cleaning cotton shaft, and the shaft is located in the first storage ash-pit, the shaft
Middle part is provided with brush tube, and runner is connected in the shaft of brush tube two sides, is connected in the grey groove sidewall of the first storage
The free end of gray moving plate, the gray moving plate stretches in the hairbrush of brush tube.
The above structure, cleaning cotton wipe blackboard up and down, and chalk dust is covered by blackboard eraser body, and wherein idler wheel is fitted in blackboard
Upper drive shaft rotation and brush tube rotation, hairbrush adhere in rotary course and accept chalk dust, and the hairbrush for being infected with dust turns
It moves to inside and is stirred by gray moving plate, the dust on hairbrush is allocated to inside the first storage ash-pit.
Preferably, the front end face of the cleaning cotton is higher than the front end face of blackboard eraser body.Cleaning cotton has elasticity, when pushing
Guarantee that cleaning cotton is tightly contacted with blackboard, effectively prevent using for a long time so that cleaning cotton collapses causes by blackboard eraser body frame sky
Blackboard can not be touched.
Preferably, being located in the cleaning cotton upper and lower sides grey groove sidewall of the first storage adjacent with cleaning cotton has the second storage grey
Slot.The chalk dust in the first storage ash-pit above cleaning cotton is fallen in the second storage ash-pit, and dust is effectively prevent to trickle down away.
Preferably, being located at oriented cleaning cotton one in the cleaning cotton upper and lower sides grey groove sidewall of the first storage opposite with cleaning cotton
The gear ash that side extends prolongs, and the gear ash prolongs outer end face and is in the same plane with blackboard eraser body front end face.Prolonged by gear ash anti-
First chalk dust that stores up ash-pit in of the stop bit below cleaning cotton is trickled down out.
Preferably, the hairbrush on the brush tube extends to outside the first storage ash-pit.Guarantee the hairbrush and blackboard on brush tube
It comes into full contact with, not only with the chalk dust on blackboard cleaning but also can accept the chalk dust fallen down, and can preferably adhere to chalk
Ash.
The beneficial effects of the utility model are: the utility model structure is simple, pass through hairbrush and storage ash-pit storage storage ash
Dirt, containment dust from flying solve dust pollution, and the injury to human body is effectively reduced.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the left view structural representation of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1 to Figure 2, including blackboard eraser body 1,1 rear end face of blackboard eraser body are connected with 2 front end face of handle company
It is connected to cleaning cotton 3, the front end face of cleaning cotton 3 is higher than the front end face of blackboard eraser body 1.1 front end face of blackboard eraser body is around wiping
First storage ash-pit 4 of the oriented lower recess of cotton 3, about 3 two sides of cleaning cotton are horizontally disposed shaft 5, and shaft 5 is located at the first storage ash-pit
In 4, brush tube 6 is provided in the middle part of shaft 5, the hairbrush on brush tube 6 extends to outside the first storage ash-pit 4.Positioned at 6 two sides of brush tube
Shaft on be connected with runner 7, wherein the front end face of the outer peripheral surface outermost of runner 7 beyond cleaning cotton 3 and be located at cleaning cotton 3
