Abstract
The invention provides a dust absorption blackboard eraser, which comprises bristles, an absorption port, an absorption cavity, an air extracting pump and a power supply, wherein the absorption port is formed at the part of the bristles of the dust absorption blackboard eraser, the absorption port is connected with the absorption cavity arranged in the dust absorption blackboard eraser, the absorption cavity is provided with a discharge port and the discharge port is positioned on the side surface of the dust absorption blackboard eraser; the air extracting pump is positioned in the dust absorption blackboard eraser and communicated with the absorption cavity through a flexible pipe; and the air extracting pump is connected with the power supply through a circuit. Through the arrangement of the absorption cavity, the air extracting pump and other parts on the blackboard eraser, the dust absorption blackboard eraser exerts the dust absorption effect and further achieve the purpose of absorbing chalk dust, the structure of the dust absorption blackboard eraser is simple and the dust absorption blackboard eraser is convenient to use; and the flying chalk dust generated when a blackboard is cleaned with an eraser can be effectively sucked away, thereby preventing the chalk dust from polluting the environment and contaminating clothes and bodies of surrounding people.
Description
Technical field
The present invention relates to blackboard eraser, relate in particular to a kind of dust absorption blackboard eraser.
Background technology
The blackboard right and wrong are the educational aid of usefulness usually, and the teacher reaches the purpose of educating the student by write the content of courses on blackboard with chalk.The word that writes with chalk can cause a lot of chalk dusts, has wave contaminated environment and descending slowly and lightly to teacher, student's body of a lot of chalk dusts when using blackboard eraser to erase the board, the clothing and be exposed to outer hair, skin made dirty.Now also there is not blackboard eraser can reduce the problem of waving of chalk dust.
Summary of the invention
The invention provides a kind of dust absorption blackboard eraser, realize the dust suction effect of blackboard eraser, reach the purpose that absorbs chalk dust by parts such as absorbing cavity and aspiration pump are set on the blackboard eraser.
The present invention is a kind of dust absorption blackboard eraser, and is concrete, and described dust absorption blackboard eraser comprises bristle, absorbs mouth, absorbing cavity, aspiration pump, power supply; Described dust absorption blackboard eraser partly has at bristle and absorbs mouthful, described absorb mouthful and be arranged on dust absorption blackboard eraser in absorbing cavity link to each other, described absorbing cavity is provided with outlet, described outlet is positioned at the side of dust absorption blackboard eraser; Described aspiration pump is positioned at dust absorption blackboard eraser, is connected with described absorbing cavity by flexible pipe; Described aspiration pump links to each other with power circuit.
Above-mentioned dust absorption blackboard eraser, wherein, described absorption mouth is provided with baffle plate, and described baffle plate is by Electric Machine Control.
Above-mentioned dust absorption blackboard eraser, wherein, the outlet of described absorbing cavity is provided with cover plate.
Above-mentioned dust absorption blackboard eraser, wherein, described bristle is that synthetic material is made.
Above-mentioned dust absorption blackboard eraser, wherein, described switch is connected with power circuit.
Above-mentioned dust absorption blackboard eraser, wherein, described power supply is a battery.
Dust absorption blackboard eraser of the present invention many beneficial effects are arranged: simple in structure, easy to use, practical; Can effectively siphon away when erasing the board the chalk dust dust that waves that produces, prevent that chalk dust is to the pollution of environment and to the contamination of surrounding population clothing, health.
Description of drawings
Fig. 1 is the structural representation of dust absorption blackboard eraser of the present invention.
The specific embodiment
With reference to Fig. 1, concrete enforcement of the present invention is described below:
As shown in Figure 1, the invention provides a kind of dust absorption blackboard eraser, described dust absorption blackboard eraser comprises bristle 2, absorbs mouth 3, absorbing cavity 1, aspiration pump 5, power supply 4; Described dust absorption blackboard eraser has in bristle 2 parts and absorbs mouth 3, described absorb mouthfuls 3 and be arranged on dust absorption blackboard eraser in absorbing cavity 1 link to each other, absorb mouthful 3 baffle plates 9 that are provided with by Electric Machine Control, described absorbing cavity 1 is provided with outlet, and described outlet is positioned at the side of dust absorption blackboard eraser; Described aspiration pump 5 is positioned at dust absorption blackboard eraser, is connected with described absorbing cavity 1 by flexible pipe 8; Described aspiration pump 5 links to each other with power supply 4 circuit; Described power supply 4 is a dry cell, and power supply 4 is connected by switch 7 controls.During use, open switch 7, Electric Machine Control baffle plate 9 is opened, and aspiration pump 5 from absorbing mouthful 3 suction, is realized the collection of chalk dust with air and chalk dust; Close switch 7, baffle plate 9 resets to seal and absorbs mouth 3, prevents that chalk dust from spilling, and also aspiration pump 5 cuts out simultaneously.When chalk dust in the absorbing cavity 1 amasss completely, open cover plate 6, chalk dust is poured out cleaning, cover cover plate 6 again and just can continue to use dust absorption blackboard eraser of the present invention.
More than specific embodiments of the invention are described in detail, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and substituting also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of being done under the spirit and scope of the present invention, all should contain within the scope of the invention.
