Preferably, the number of the dust suction ports is at least 8, a plurality of fan-shaped baffles are arranged in the dust suction ports, and the fan-shaped baffles are made of silica gel materials.

Preferably, the soft brush is fixedly connected to the edge of the bottom surface of the dust collection box, and the soft brush is provided with multiple layers to form a closed check ring structure.

Preferably, the electric brush heads are electrically connected to the battery, and the number of the electric brush heads is at least 3.

Preferably, the ash outlet and the charging port are both movably connected with sealing covers.

Preferably, the filter screen is a filter screen special for a dust collector.

Preferably, the dust collecting box is made of transparent PVC materials.

The utility model has the advantages that: structural design is reasonable, clears up different writings on the blackboard through the electronic brush head of adjustable, and the pappus brush can effectively prevent to produce the raise dust when the brush head is rotatory, and intensive pappus brush changes simultaneously and forms the negative pressure ware, increases and inhales the clean degree, and not only application method is simple, and the filter screen can be dismantled in addition, is convenient for clear up.

Detailed Description

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.

As shown in fig. 1-3, a miniature electric dust-collecting blackboard eraser comprises a dust collecting box 1 and a handle 6, wherein the dust collecting box 1 is made of transparent PVC material, a bottom plate of the dust collecting box 1 is provided with a plurality of dust collecting ports 2, at least 8 dust collecting ports 2 are provided, a plurality of fan-shaped baffles 3 are arranged in the dust collecting ports 2, the plurality of fan-shaped baffles 3 just completely shield the dust collecting ports 2 in a static state, and the fan-shaped baffles 3 are made of silica gel material; the bottom surface of the bottom plate is fixedly connected with a soft brush 4 and an electric brush head 5, the soft brush 4 is fixedly connected with the edge of the bottom surface of the dust collection box 1, the soft brush 4 is provided with a plurality of layers to form a closed check ring structure, the dust raising condition generated when the brush head rotates can be prevented, and meanwhile, the soft brush is more dense, a negative pressure device is easier to form, and the absorption degree is increased; the side surface of the dust collecting box 1 is provided with an ash outlet, and a sealing cover 9 is movably connected on the ash outlet;

the bottom of the handle 6 is detachably connected with the dust collecting box 1, a filter screen 7 is fixedly connected at the joint of the handle 6 and the dust collecting box 1, and the filter screen 7 is a special filter screen for a dust collector; a battery 8, a brush head motor 10 and a dust collection motor 11 are arranged in the handle 6, a charging port of the battery 8 is positioned on the side surface of the handle 6, and a sealing cover 9 is movably connected on the charging port; the brush head motor 10 is electrically connected with the electric brush head 5, and the dust suction port 2 of the dust suction motor 11 is arranged right opposite to the filter screen 7; the top surface of handle 6 is equipped with regulating switch 12, and regulating switch 12 electric connection is in brush head motor 10, and regulating switch 12 can adjust the rotational speed of brush head motor 10.
