Description

Chalk eraser dust collector

Technical Field

The utility model relates to a chalk eraser dust catcher belongs to the teaching aid field.

Background

Millions of teachers in China use chalks to write on boards in class, a large amount of dust is generated during wiping, and after inhalation, the teachers may cause discomfort of the nose, the throat and even respiratory diseases and lung diseases. Aiming at the problem, the chalk eraser with the dust collection function can reduce the harm of chalk dust to teachers to a certain extent.

However, the existing dust collection chalk eraser has obvious defects in dust collection, for example, in the novel dust collection chalk eraser disclosed in patent CN209111828U, the motor drives the air suction blade and the brush head to rotate, and the air outlet and the filter cloth are arranged on the side surface of the shell to realize electric wiping and dust collection.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned not enough, the utility model provides a collect clean with dust absorption in chalk eraser dust catcher of an organic whole, the utility model discloses a technical scheme as follows:

a chalk eraser dust collector comprises a shell, a dust collection component, an eraser plate component and a dust collection box; the dust collection assembly comprises an electromechanical box arranged on the inner bottom of the shell, a rechargeable battery and a motor which are arranged in the electromechanical box, a rotating shaft connected with an output shaft of the motor, and a suction fan blade arranged on the rotating shaft; the wiping plate component comprises a grid frame arranged at the upper end of the rotating shaft and a plurality of circles of wiping cotton arranged on the grid frame at intervals; the dust collecting box is movably inserted in the lower side part of the shell, a filter screen is arranged on an inner side plate of the dust collecting box, a plurality of dust collecting screen plates are arranged in the dust collecting box at intervals, and a top plate of the dust collecting box is provided with exhaust holes.

Further, a charging plug and a switch button of the rechargeable battery are mounted on the shell.

Furthermore, the wiping cotton is provided with a beveled dust guide port.

Furthermore, the mesh apertures of the plurality of dust collecting net plates are gradually reduced from bottom to top.

Furthermore, the wiping cotton is provided with a beveled dust guide port.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a motor drive wipes board subassembly and suction fan blade rotation, realizes automatically cleaning and dust absorption. The dust is guided into the inner cavity of the shell through a dust guide port obliquely cut on the cotton wiping piece. The dust collection and collection net frame which is vertically and horizontally arranged is formed by the filter screen and the dust collection net plate which are arranged on the dust collection box, the power and the speed of air flow are reduced to reduce the dust to be discharged along with the exhaust holes, and the filter screen and the dust collection net plate are used for adsorbing and collecting the dust to improve the dust collection effect.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a cross-sectional view of FIG. 1;

fig. 3 is a half-sectional view of the dust collecting box of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1-3, a chalk eraser dust collector includes a housing 1, a dust collecting assembly, an eraser plate assembly and a dust collecting box 2; the dust collection assembly comprises an electromechanical box 3 arranged on the inner bottom of the shell 1, a rechargeable battery 4 and a motor 5 which are arranged in the electromechanical box 3, a rotating shaft 6 connected with an output shaft of the motor 5, and a suction fan blade 7 arranged on the rotating shaft 6; the wiping plate component comprises a grid frame 8 arranged at the upper end of the rotating shaft 6 and a plurality of circles of wiping cotton 9 arranged on the grid frame 8 at intervals; the dust collecting box 2 is movably inserted into the lower side part of the shell 1, a filter screen 10 is arranged on the inner side plate of the dust collecting box 2, a plurality of dust collecting screen plates 11 are arranged in the dust collecting box 2 at intervals, and a vent hole 12 is arranged on the top plate of the dust collecting box 2.

Further, a charging plug (not shown) and a switch button 13 of the rechargeable battery 4 are mounted on the housing 1.

Furthermore, the wiping cotton 9 is provided with a beveled dust guide port 14.

Further, the mesh apertures of the plurality of dust collecting net plates 11 are gradually reduced from bottom to top.

When the dust collection box is used, the switch button is pressed to start the motor, the motor drives the cotton wiper and the suction fan blade to rotate, the cotton wiper wipes chalk blackboard writing, the suction fan blade rotates to generate suction airflow to suck dust into the inner cavity of the shell from the grating frame, the dust airflow is subjected to multiple choked flow, adsorption and collection through the filter screen and the dust collection screen plate and then is discharged through the exhaust holes, and most of the dust is adsorbed on the screen cloth and collected in the dust collection box.

The foregoing is a preferred embodiment of the present invention, and it should be noted that for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
