Description

Blackboard eraser with self-priming dust structure

Technical field

The utility model relates to the technical field of teaching appliance, particularly a kind of blackboard eraser with self-priming dust structure.

Background technology

General blackboard eraser only has the function of wiping ash, and the clash dust that comes is generally had only random having floated everywhere, and for the blackboard eraser of inhaling the method structure, its structure is comparatively complicated, and also comparatively inconvenience of operation, be that the Chinese utility model patent " dust absorption blackboard eraser " (notification number is CN2540290Y) of ZL02211686.9 is exactly this type of design as the patent No.; It mainly is made of dirt case, motor, switch, brush, blade, battery, housing, air suction opening, dust-exhausting port.Motor is pasted the centre position that is vertically mounted on the dirt case, and battery is pasted the interior location that is installed in housing, and air suction opening boring is evenly distributed on the back position of housing.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of rational in infrastructure, easy to use and have a blackboard eraser with self-priming dust structure of inhaling ash, the grey dual-use function of storage.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the blackboard eraser with self-priming dust structure, comprise the wiping board housing, this wiping board housing is shaped on the die cavity of indent, the front end of this die cavity is equipped with the brush board body, be fitted with dust suction subassembly in the die cavity, this dust suction subassembly includes fan body, and the front end of this fan body and the brush board body back side face; Wiping board housing one side also is shaped on ash storage box, and the ash charge mouth of this ash storage box is right against in the die cavity.

The measure of taking also comprises:

The rear end of above-mentioned fan body drives and is connected with actuating unit, and this actuating unit and above-mentioned wiping board housing die cavity rear wall are fixedly connected.

Above-mentioned brush board body is a cavernous body.

Be equipped with power source body on the above-mentioned wiping board housing, and this power source body is connected with above-mentioned actuating unit.

Be embedded with in the above-mentioned power source body voltage be at least six volts at least two the joint dry cells.

Above-mentioned wiping board housing one side is shaped on the lever body.

Compared with prior art, the utility model comprises the wiping board housing, and this wiping board housing is shaped on the die cavity of indent, the front end of this die cavity is equipped with the brush board body, be fitted with dust suction subassembly in the die cavity, this dust suction subassembly includes fan body, and the front end of this fan body and the brush board body back side face; Wiping board housing one side also is shaped on ash storage box, and the ash charge mouth of this ash storage box is right against in the die cavity.Advantage of the present utility model is: near closed hollow ring is set up at the back side at the brush board body, and in this die cavity, be equipped with dust suction subassembly, the dust that the brush board body is produced can total number be drawn in the die cavity at rear portion, and dust will wave no longer everywhere, has improved mopper's physical and mental health effectively; Be loaded with ash storage box in die cavity one side, and this ash storage box is mainly used in the dust that reservoir sucks, it is reasonable in design; The ash storage box volume is big, and it is strong, easy to use once to store grey ability.

Description of drawings

Fig. 1 is vertical cross-sectional schematic of the utility model embodiment;

Fig. 2 is the schematic top plan view of Fig. 1;

Fig. 3 is that schematic diagram is looked on the left side of Fig. 1.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
