Therefore need badly in the middle of prior art and want a kind of new technical scheme to solve this problem.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of Portable dust obsorption blackboard eraser, there is existing dust-removing blackboard eraser complex structure, cost is high, heaviness is not portable, the technical problem that dust collection rate is not high with solving in prior art.
The Portable dust obsorption blackboard eraser that the utility model provides, shell, blackboard eraser brush, filter bag, battery, motor, fan, screen pack, airflow distribution device, shift knob, spring connect button, charging inlet, handle, one end of described shell is fixedly connected with blackboard eraser brush by screw, and the other end of shell is provided with charging inlet; Described blackboard eraser brush is provided with air suction opening, and blackboard eraser brush is connected with filter bag by air suction opening; Described filter bag is arranged on the inside of shell, and filter bag is connected with shell by draw-in groove; Described battery is inlayed and is arranged on shell, and battery is connected with motor by wire; Described motor and fan are all fixedly mounted on the inside of shell, and motor is fixedly connected with fan with wire by pin; Described screen pack is arranged on the air port place of fan, and screen pack is connected with shell by draw-in groove; Described airflow distribution device is fixedly connected with the sidewall of shell by screw; Described shift knob is connected with the sidewall external stability of shell, and shift knob is connected with battery by wire; Described spring connects button and is connected with the sidewall external stability of shell; Described charging inlet is connected with battery by wire.
Described handle is fixedly connected with shell by screw thread.
Described blackboard eraser brush is cavernous body.
The utility model can bring following beneficial effect: Portable dust obsorption blackboard eraser has gravitational settling and the dual mechanism of gathering dust of airflow filtering, has that dust-collecting efficiency is high, structure is simple, deashing is convenient, cost is low, reliability high.Operator can carry out control machine by gauge tap, simply easy to operate, saves time, laborsaving, has very strong practicality.Blackboard eraser brush is cavernous body simultaneously, can be not enough at battery electric quantity, when can not charge in time again, provides work with Portable dust obsorption blackboard eraser, is soaked by cavernous body, play the effect of dedusting.
Accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model Portable dust obsorption blackboard eraser stravismus structural representation.
Fig. 2 is that the utility model Portable dust obsorption blackboard eraser faces structural representation.
In figure, 1-shell, 2-blackboard eraser brush, 3-filter bag, 4-battery, 5-motor, 6-fan, 7-screen pack, 8-airflow distribution device, 9-shift knob, 10-spring connect button, 11-charging inlet, 12-handle.
Detailed description of the invention
As shown in the figure, Portable dust obsorption blackboard eraser, it is characterized in that: comprise shell 1, blackboard eraser brush 2, filter bag 3, battery 4, motor 5, fan 6, screen pack 7, airflow distribution device 8, shift knob 9, spring connection button 10, charging inlet 11, handle 12, one end of described shell 1 is fixedly connected with blackboard eraser brush 2 by screw, and the other end of shell 1 is provided with charging inlet 11; Described blackboard eraser brush 2 is provided with air suction opening, and blackboard eraser brush 2 is connected with filter bag 3 by air suction opening; Described filter bag 3 is arranged on the inside of shell 1, and filter bag 3 is connected with shell 1 by draw-in groove; Described battery 4 is inlayed and is arranged on shell 1, and battery 4 is connected with motor 5 by wire; Described motor 5 and fan 6 are all fixedly mounted on the inside of shell 1, and motor 5 is fixedly connected with fan 6 with wire by pin; Described screen pack 7 is arranged on the air port place of fan 6, and screen pack 7 is connected with shell 1 by draw-in groove; Described airflow distribution device 8 is fixedly connected with by the sidewall of screw with shell 1; Described shift knob 9 is connected with the sidewall external stability of shell 1, and shift knob 9 is connected with battery 4 by wire; Described spring connects button 10 and is connected with the sidewall external stability of shell 1; Described charging inlet 11 is connected with battery 4 by wire.
