Abstract
The utility model discloses a dust exhaust device of an electric tool, which is arranged on the electric tool and comprises a machine body, wherein a motor is arranged in the machine body and is connected with a saw blade, and the motor is provided with a heat radiating fan. The dust exhaust device of the electric tool comprises a dust cover which is matched with the saw blade, and also comprises two circles of dust outlets, wherein the two circles of dust outlets comprise the inner circle of dust outlets and the outer ring of dust outlets, the inner circle of dust outlets is communicated with the dust cover, the outer circle of dust outlets is communicated with an air flue, and the air flue is matched with the heat radiating fan. After the structure is adopted, the dust exhaust device has the advantages of better dust exhaust effect, reasonable structure and lower cost.
Description
Technical field
The present invention relates to electric tool component technology field, especially relate to a kind of electric tool dust exhaust.
Background technology
Electric tools such as groover can produce a large amount of dust in use, and people extremely hope and can these dust in time be got rid of, thereby good working environment are provided for the operator.Therefore, the saw blade place of electric tool is provided with dust cover more, and the dust that saw blade produces can be got rid of under the guiding of this dust cover.But because mostly dust cover is the trend of passive guidance dust, thereby institute's Dust Capacity of arranging is less, and effect is ideal not to the utmost.Therefore be necessary to improve.
Summary of the invention
Deficiency to above-mentioned prior art exists the purpose of this invention is to provide a kind of electric tool dust exhaust, and it has the preferable characteristics of dust discharge effect.
To achieve these goals, the technical scheme that the present invention adopted is: the electric tool dust exhaust is installed on the electric tool; This electric tool comprises fuselage, is provided with motor in the fuselage, and motor is connected with saw blade; And motor has radiator fan, and this electric tool dust exhaust includes dust cover, and this dust cover and saw blade match; Said electric tool dust exhaust comprises the Shuan Quan dust mouth, and this Shuan Quan dust mouth comprises inner ring and outer ring, and inner ring and dust cover are communicated with; The outer ring is communicated with the air channel, and air channel and radiator fan match.
Said Shuan Quan is fixed on the dust cover dust mouth.
After adopting said structure, the present invention compares the advantage that is had with prior art and is: 1, dust discharge effect is preferable.The dust cover of electric tool dust exhaust of the present invention is communicated in the inner ring of Shuan Quan dust mouth, and the outside of inner ring is provided with the outer ring, and outer ring and radiator fan are communicated with.Like this, the discharge of the wind that radiator fan blew out in the outer ring, thus the oral area of inner ring forms negative pressure.The inner dust of this vacuum suction dust cover is discharged rapidly in inner ring, has avoided the situation of the passive dust discharge of dust cover.2, rational in infrastructure, cost is lower.Electric tool dust exhaust of the present invention has made full use of electric tool radiator fan and protective cover, does not need other power set, and is very reasonable; The parts that increased are less, and preparation cost is lower.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the perspective view (broken section) of embodiments of the invention;
Fig. 2 is the main TV structure sketch map (broken section) of embodiments of the invention.
The specific embodiment
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see illustrated in figures 1 and 2: the electric tool dust exhaust is installed on the electric tool.This electric tool comprises fuselage 10, is provided with motor in the fuselage 10, and motor is connected with saw blade 20, and motor has radiator fan 60.This electric tool dust exhaust includes dust cover 30, and this dust cover 30 matches with saw blade 20.That is: dust cover 30 is saw blade 20 semi-surroundings, thereby the guiding dust is discharged along this dust cover 30.Dust cover 30 is provided with Shuan Quan dust mouth 40, and this Shuan Quan dust mouth 40 comprises inner ring 41 and outer ring 42.That is, outer ring 42 is enclosed within inner ring 41 outsides.Wherein, inner ring 41 is communicated with dust cover 30, and outer ring 42 is communicated with air channel 50, and air channel 50 matches with radiator fan 60.So-called air channel 50 and radiator fan 60 match and refer to the wind that radiator fan 60 blows out and get in the air channel 50.
Operation principle of the present invention: the wind that radiator fan 60 blows out blows out from outer ring 42 via air channel 50.At this moment, the oral area of inner ring 41 forms negative pressure.Because dust cover 30 is communicated with inner ring 41, then dust receives the attraction of inner ring 41 oral area negative pressure in the dust cover 30, the outlet of pouring into inner ring 41 in a large number and rapidly, thus in time discharge via inner ring 41.
