Technical field

The utility model relates to a kind of blackboard eraser, relates in particular to a kind of dust-collecting type semiautomatic blackboard eraser.

Background technology

Existing dust-removing blackboard eraser substantially all is full-automatic or complete manual.For the full rotation type dust-removing blackboard eraser, not only there is the not good problem of pick-up performance in it, and exists because the internal circuit configuration complexity causes low problem of price height, service life; For full hand dust-removing blackboard eraser, there is inconvenient problem with use in it, has brought certain inconvenience to classroom instruction like this, and simultaneously there is the problem that can cause chalk dust to fly upward in the use everywhere in it, and teachers and students' health has been caused certain infringement.

Summary of the invention

Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of dust-collecting type semiautomatic blackboard eraser that can effectively remove the dust that produces in the process of erasing the board that provides.

The purpose of this utility model is achieved in that

A kind of dust-collecting type semiautomatic blackboard eraser, comprise blackboard eraser, described blackboard eraser is by the hairbrush of bottom, the drain pan of hairbrush upper end, the box body of drain pan upper end constitutes, the bottom of box body inside is provided with housing, the edge of housing bottom is closed the connection with drain pan, the opening of housing upper end is connected with an end of wireway, the ash inlet of U-shaped shell is connected on the wireway other end and the dust arrester, wireway inside is provided with impeller, one end of impeller and first trace is fixed, the other end of first trace passes wireway and is connected by gear with second trace of motor, and motor is by the power supply power supply that is installed on box body inside, and box body is provided with gauge tap.

Said brush and gapping interval are distributed on the drain pan, and hairbrush is used for chalk dust from the blackboard brush down, and chalk dust can enter the housing from the space.

Above-mentioned housing is tetrapyamid shape.

Above-mentioned dust arrester is made of the U-shaped shell of outside, the cavernous body on the U-shaped outer casing inner wall, before use with the cavernous body water-soaked.

Above-mentioned cavernous body is that zigzag is distributed in U-shaped outer casing inner wall.

The tooth of zigzag cavernous body is to tilt along the passage airintake direction, and the inclination angle is 60 degree.

The part that impeller is installed on above-mentioned motor and the wireway is located in the outer middle cavity of U-shaped shell.

Last first trace is fixed by the network structure that is installed on wireway inside.

The gear ways of connecting is that two orthogonal bevel gear engagements form.

Above-mentioned power supply is battery.

The utility model has been obtained following technique effect:

At first, the utility model has adopted in blackboard eraser inside and has been provided with impeller, and impeller can suck and collect blackboard eraser inside with the dust under the hairbrush brush effectively by electric motor driven structure; Secondly, the cavernous body indentation, and be 60 degree inclinations angle along the passage airintake direction and tilt, make the dust and the cavernous body that enter into U-shaped enclosure that bigger contact area be arranged, can fully be adsorbed by moistening sponge.

The specific embodiment

A kind of dust-collecting type semiautomatic blackboard eraser as shown in Figure 1, comprise blackboard eraser, described blackboard eraser is by the hairbrush 1 of bottom, the drain pan 3 of hairbrush 1 upper end, the box body 2 of drain pan 3 upper ends constitutes, the bottom of box body 2 inside is provided with housing 4, the edge of housing 4 bottoms is closed the connection with drain pan 3, the opening of housing 4 upper ends is connected with an end of wireway 5, the ash inlet 7 of U-shaped shell 12 is connected on wireway 5 other ends and the dust arrester 6, wireway 5 inside are provided with impeller 8, one end of impeller 8 and first trace 9 is fixed, second trace 11 that the other end of first trace 9 passes wireway 5 and motor 10 is connected by gear, motor 10 is by power supply 15 power supplies that are installed on box body 2 inside, and box body 2 is provided with gauge tap 16.Housing 4 is tetrapyamid shape.

As shown in Figure 2, the part that impeller 8 is installed on motor 10 and the wireway 5 is located in the U-shaped shell 12 outer middle cavitys 14.

As shown in Figure 3, hairbrush 1 is spaced apart on drain pan 3 with space 12.

As shown in Figure 4, first trace 9 is fixing by the network structure 17 that is installed on wireway 5 inside.
