Abstract

The utility model discloses an electric dust-absorbing eraser, which relates to the writing and erasing appliance. The utility model solves the problems that the prior art has the slow erasing speed and bad dust removing effect, the use of the battery causes the increasing of the cost, and a hair brush is uneasy to change. The utility model is composed of a motor, blades and a switch and is characterized in that the electric dust-absorbing eraser is also provided with a changeable hair brush, a device reducing the friction, a dust-collecting box, a wind gathering housing, a handle, a damper spring, the protecting housing of the motor, the sponge, etc. The utility model is mainly used for erasing the blackboard, changing the changeable hair brush and enlarging the purposes, such as cleaning cars, leather shoes, etc.

Description

Electric dust-absorbing eraser

The utility model relates to a kind of writing and wipes apparatus.

" electric dust absorption blackboard eraser " (CN2030952U) in, a kind of blackboard eraser is disclosed, form by blade (1), flabellum (2), laying dust box (8), micromotor (12), the back drives blade (1), flabellum (2) rotates to be characterized in slowing down micro machine (12), and blade is equipped with hairbrush on (1); One subplate (4) is set in the space behind the flabellum (2), is being covered with tiny conical through-hole on it, the large aperture of conical through-hole is towards flabellum (2).This utility model has solved the dust that produced of in the past manually erasing the board effectively to the harm of teachers and students' health, but this utility model also has the following disadvantages: 1, the vanes belt back speed of slowing down is slow, and pick-up performance is poor; 2, motor provides power supply with battery, and expense is increased; 3, hairbrush is difficult for changing.

The purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of good dedusting effect to be provided, the electric dust absorption blackboard eraser that uses alternating current, hairbrush to change easily.

The purpose of this utility model can reach by following measure: electric dust absorption blackboard eraser, comprise motor (2), blade (9), switch (13), it is characterized in that it also comprises easy Brusher being able to change bristles (7), laying dust box (4), wind gathering shell (11), handle (3), buffer spring (8); Blade (9) and easy Brusher being able to change bristles (7) are contained on the axle of motor (2).

The purpose of this utility model can also reach by following measure: easily Brusher being able to change bristles (7) by the same shape of two-phase, have the clamping plate of screw hole, middle clamping hairbrush also is screwed and makes; Wind gathering shell (11) front is equipped with and is reduced rubbing device (10), and reducing rubbing device (10) is the rolling ball; Several steam vents (15) are arranged on the box body of laying dust box (4), and its positive openable laying dust box (4) inwall posts sponge (5); Wind gathering shell (11) also has a hole in tangential direction.

The utility model compared with prior art has the following advantages:

1, wiping speed is fast, good dedusting effect;

2, use civilian alternating current as power supply, convenient, cost is low;

3, hairbrush is easily changed, and changes different hairbrush, but purposes enlarges.

Fig. 1 is a cutaway view of the present utility model.

Fig. 2 is a front view of the present utility model.

Be described in further detail below in conjunction with Fig. 1,2 pairs of enforcements of the present utility model:

The utility model comprises motor (2), blade (9), switch (13), also comprises easy Brusher being able to change bristles (7), reduces rubbing device (10), laying dust box (4), wind gathering shell (11), handle (3), buffer spring (8), electric motor protecting shell (1), sponge (5), coupling nut (6) (14), helical form electric wire (12).After connecting civilian alternating current, open switch, motor (2) drives blade (9), the easily coaxial rotation of Brusher being able to change bristles (7), easy Brusher being able to change bristles (7) blackboard wiping, blade (9) is sent into laying dust box (4) with dust by the hole of wind gathering shell (11) tangential direction, air is discharged by steam vent (15), dust filters through sponge and stays in the laying dust box, the front of laying dust box (4) can be opened, so that cleaning dust and replacing sponge are screwed during use, the shape of laying dust box (4) can also be done ovalisation or semicircle; Reducing rubbing device (10) is the rolling ball, and the utility model is moved flexibly on blackboard, and quantity is advisable with three; Buffer spring (8) can be alleviated in the use the axial compressive force of motor shaft, and handle (3) is fixed on the electric motor protecting shell (1) with screw; Electric motor protecting shell (1) is screwed the back in wind gathering shell (11).

Claims
