Abstract

The utility model discloses a hand-held electric drill with an automatic dust remover, which relates to the hand-held electric drill, more specifically, the hand-held electric drill capable of automatically absorbing flying dust generated during the process of drilling. The utility model is composed of a conventional hand-held electric drill part, a dust absorption cover of a dust absorption part, an air conducting passage, blades and a dust deposition filtering bag. Through the high-speed rotation of the blades coaxially connected with the axis of the electric drill, negative pressure is formed in the air conducting passage and the dust absorption cover, and air stream generated thus delivers the flying dust generated by the drill from the dust absorption cover to the dust deposition filtering bag for accumulation through the air conducting passage. The air purified by the dust deposition filtering bag is directly exhausted from an exhaust outlet. Because the utility model reduces the pollution generated during the work of the electric drill, the physical health of operating staff is protected; no operation is added, when the hand-held electric drill works normally, the function of dust absorbing is simultaneously finished; the utility model is simple in structure and easy in use.

Description

Automatic dedusting electric hand drill
Technical field
The utility model relates to a kind of electric hand drill (containing electric impact drill), specifically, relates to a kind of automatic absorption and executes the electric hand drill (containing electric impact drill) that produces flying dust when boring.
Background technology
Electric hand drill (containing electric impact drill) enters huge numbers of families in a large number as a kind of civilian use electric instrument, occupies certain status in people's life staying idle at home.Along with the raising of people's standard of living, the rise of house decoration upsurge, the condition during to environmental protection and work has had higher requirement.Simultaneously, the flexible portability of electric hand drill makes it widely to use in industrial and agricultural production, and it is imperative to carry out dustless operation.Existing various electric hand drill does not possess this function, can produce a large amount of flying dust when drill bit rotates at a high speed to execute when boring, and healthy unfavorable to the staff, produced simultaneously pollution makes troubles for follow-up cleaning.
Summary of the invention
The purpose of this utility model just is to overcome the problems referred to above that existing electric hand drill exists, and a kind of automatic dedusting electric hand drill (containing electric impact drill) is provided.
The purpose of this utility model is achieved in that by dust shield, air guide channel, flabellum, the laying dust filter bag of conventional electric hand drill part and vacuum part to be formed.By rotating with the high speed of the coaxial flabellum that links to each other of electric drill rotating shaft, in air guide channel and dust shield, form negative pressure to a certain degree, utilize consequent air-flow, from dust shield the flying dust that drill bit produces is sent to savings the laying dust filter bag by air guide channel, by the air that the laying dust filter bag purified, directly discharge by exhaust outlet.
The utlity model has following advantage and good effect:
1. pick-up performance is good, the pollution that produces when reducing electric drill work, and the protection staff is healthy.
2. do not have additional operations, when the electric hand drill operate as normal, dust-absorbing function is finished in real time.
3. simple in structure, in light weight, volume is little, implement easily.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the utility model is made up of conventional electric hand drill part and vacuum part.
Conventional electric hand drill partly comprises housing 7 (shell head 7.1, body 7.2, shell tail 7.3, handle 7.4), drill bit 8, anchor clamps 9, degree of tightness swivel head 10, rotating shaft 11, motor 12, switch 13, power line 14.
The vacuum part comprises dust shield 1, air guide channel 2, flabellum 3, laying dust filter bag 4, exhaust outlet 5, screw 6; Dust shield 1 is fixed on the upper front end and the bottom of shell head 7.1 by screw 6, on shell head 7.1 passage is arranged, and the two sides of shell head 7.1 is connected with air guide channel 2, and air guide channel 2 rear portions are connected with laying dust filter bag 4; Flabellum 3 is installed on the tail end of rotating shaft 11; Exhaust outlet 5 is arranged on shell tail 7.3.
Dust shield 1 is divided into capouch 1.1, cover body 1.2, cover tail three parts; Wherein capouch 1.1 is the short tube of a kind of transparent organic glass or fiberglass, has air-vent on it; Cover body 1.2 is the long tube of a kind of transparent compressible ripple; Cover tail 1.3 is a kind of bowl-shape cover.
Air guide channel 2 is horn-like, the middle passage of tubulose that is for a kind of two.
Laying dust filter bag 4 is a kind of screen pack that micropore is arranged.
Experiment detects, and this novel electric drill can absorb 90% or more the flying dust of generation when being worked by electric drill.
