Abstract
The invention discloses a non-sticky wind-force dust-absorption chalk eraser, which comprises a chalk eraser body, a high-density soft brush, an air suction port, a dust absorption pump, a collection box and a wind-force driving wheel, wherein a dust removal part of the chalk eraser adopts a plastic material to replace the traditional materials such as asbestos, cloth and the like, the dust removal part adopts a high-density soft brush structure, the writing of a blackboard can be removed during erasing, meanwhile, chalk dust cannot be stuck on the brush, the blackboard is guaranteed not to be scratched in the dust removal process, and the problems that the chalk dust is continuously stuck and is difficult to remove in the using process of the traditional chalk eraser are well solved.
Description
Technical Field
The invention relates to a non-sticky wind-force dust-absorbing chalk eraser.
Background
The conventional chalk eraser wipes chalk dust on a blackboard to fly randomly, so that air pollution is caused.
Disclosure of Invention
The present invention has been made to effectively solve the above problems.
The purpose of the invention is realized by the following technical scheme:
as a technical scheme, the non-sticky wind power dust collection chalk eraser comprises a chalk eraser body, a high-density soft brush, an air suction port, a dust collection pump, a collection box and a wind power driving wheel, wherein a dust removal part of the chalk eraser adopts a plastic material to replace the traditional materials such as asbestos, cloth and the like, the dust removal part adopts a high-density soft brush structure, the writing on a blackboard can be removed in the erasing process, meanwhile, chalk dust is not stuck on the brush, the blackboard is not scratched in the dust removal process, the air suction ports are formed in four side surfaces, the air suction ports are connected with the dust collection pump through thin hoses, when the dust collection pump rotates, the chalk dust in the air around the chalk eraser passes through the air suction ports and is absorbed into the dust collection pump through the thin hoses, the outlet of the dust collection pump is connected with the chalk dust collection box, the dust collection box has the effect of exhausting and not leaking the chalk dust, so that the air and the chalk dust are effectively separated, when the, the chalk eraser is taken out and washed by water, and can be reused.
According to the technical scheme, the number of the suction pumps is two, the driving wheels are provided with four wind power driving wheels, the wind power driving wheels are installed at two ends of the suction pumps and connected through a rotating shaft of the suction pumps, when the chalk eraser moves back and forth on a blackboard quickly, the wind power driving wheels start to rotate under the action of airflow and drive the rotating shaft of the suction pumps to rotate, and after the shaft rotates, the suction pumps start to work to suck dust and air around the chalk eraser into the collection box.
The chalk eraser solves the problems that the chalk dust is continuously bonded and is difficult to remove in the using process of the traditional chalk eraser.
Drawings
The invention is explained in further detail below with reference to the drawing.
FIG. 1 is a front view of a circuit structure of a non-stick wind-powered dust-collecting chalk eraser according to an embodiment of the present invention;
FIG. 2 is a top view of a non-stick wind-powered dust-collecting chalk eraser according to an embodiment of the invention:
description of the symbols of the drawings: 1. the chalk eraser comprises a chalk eraser body, 2 high-density soft brushes, 3 an air suction port, 4 a dust suction pump, 5 a collection box, 6 and a wind power driving wheel.
Detailed Description
The invention is described in detail below with reference to the following figures and examples:
as a preferred, there is not wet the wind-force dust absorption chalk eraser of sticking, including the chalk eraser body, high density soft brush, air intake, dust absorption pump, collecting box, wind-force drive wheel, the dust removal part of the chalk eraser uses the material such as the traditional asbestos, cloth, etc. to replace the plastic material, the dust removal part uses the structure of the high density soft brush, can clear away the writing of the blackboard in erasing, the chalk dust will not be adhered to the brush at the same time, and guarantee not causing the scratch to the blackboard in the course of dust removal, there are air intake on four sides, the air intake is connected with dust absorption pump through the fine hose, when the dust absorption pump rotates, the chalk dust in the air around the chalk eraser passes the air intake, absorb into the dust absorption pump through the fine hose, the outlet port of the dust absorption pump connects the chalk dust collecting box, the collecting box has effects of exhausting and not revealing the chalk dust, in this way, carry on the effective separation with the air and the chalk dust, the chalk eraser is taken out and washed by water, and can be reused.
Preferably, the number of the suction pumps is two, the driving wheels are provided with four wind-driven driving wheels, the wind-driven driving wheels are arranged at two ends of the suction pumps and are connected through a rotating shaft of the suction pumps, when the chalk eraser moves back and forth on a blackboard quickly, the wind-driven driving wheels start to rotate under the action of airflow and drive the rotating shaft of the suction pumps to rotate, and after the shaft rotates, the suction pumps start to work to suck dust and air around the chalk eraser into the collecting box.
Claims (2)
1. The non-sticky wind-force dust collection chalk eraser comprises a chalk eraser body, and is characterized by also comprising a high-density soft brush, an air suction port, a dust collection pump, a collection box and a wind-force driving wheel, wherein a dust removal part of the chalk eraser adopts a plastic material to replace the traditional materials such as asbestos, cloth and the like, the dust removal part adopts a high-density soft brush structure, the handwriting of a blackboard can be removed in the erasing process, chalk dust can not be adhered to the brush, the blackboard is not scratched in the dust removal process, the air suction ports are arranged on four side surfaces, the air suction ports are connected with the dust collection pump through thin hoses, when the dust collection pump rotates, the chalk dust in the air around the chalk eraser passes through the air suction port and is absorbed into the dust collection pump through the thin hoses, the outlet of the dust collection pump is connected with the chalk dust collection box, the effect of exhausting and not leaking the chalk dust is achieved, so that the air and the chalk dust are effectively separated, and when, the collection box is taken out and washed by water, and then can be reused.
2. The non-sticky wind-powered dust-collecting chalk eraser as recited in claim 1, wherein: the blackboard eraser is characterized in that the number of the suction pumps is two, the driving wheels are provided with four wind power driving wheels, the wind power driving wheels are installed at two ends of the suction pumps and connected through a rotating shaft of the suction pumps, when the blackboard eraser moves back and forth quickly, the wind power driving wheels start to rotate under the action of air flow, meanwhile, the rotating shaft of the suction pumps is driven to rotate, and after the shaft rotates, the suction pumps start to work to suck dust and air around the blackboard eraser into the collecting box.
