Description
Technical field
The utility model relates to a kind of wind path structure, particularly relates to a kind of wind path structure of electric tool.
Background technology
At present, the wind path design of the electric tool of prior art its object is to: for the control module in electric tool and drive motors provide heat radiation.The design of the electric tool of prior art mainly adopts two kinds of structures, and the first structure comprises electric tool body, control module and drive motors; Described drive motors is arranged in electric tool body, described control module is arranged in drive motors with the form of horizontal positioned, described control module is arranged on the rear of drive motors, the design of its wind path is the rearward openings at electric tool body, and between drive motors and control module; The second structure comprises drive motors, control module and electric tool body, described control module and electric tool body are split-type structural, control module is serially connected on the electric wire that external cord is connected with electric tool body as box body, using control module as independent heat radiation, be provided with drive motors in electric tool, described wind path design is still at the rear of electric tool.
This design Problems existing of the electric tool of currently available technology is:
The first structure Problems existing has 2 points: first is that the air port offered from electric tool rear owing to first must flow to drive motors again after control module, existence due to control module makes windage larger, radiating effect is poor, second is must to lie in a horizontal plane in electric tool body due to control module and also need leave certain space in control module and electric tool body rear, so the volume of electric tool must be sacrificed in order to the problem of dispelling the heat, cause the volume of electric tool comparatively large, radiating effect is still lower simultaneously.
The second structure Problems existing is: although control module adopted split type connected mode to solve the problem of part heat radiation, can also reduce the volume of electric tool, but such design makes the use still comparatively inconvenience of pulling of control module box body and electric tool simultaneously.
Utility model content
The utility model aims to provide and a kind ofly can reduce the wind path structure that electric tool volume provides the electric tool of radiating efficiency simultaneously further.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of wind path structure of electric tool, comprise power tool body, drive motors and control module, described drive motors and control module are arranged in power tool body successively, also comprise housing, described housing is in the control module sheathed and make control module be in sealing state, described housing is arranged in power tool body, described power tool body is provided with ventilating opening, and ventilating opening to be located on power tool body and to be positioned at housing place.
As improvement, the smooth outer surface of described housing and shape is consistent with control module shape.
As improvement, described housing is dismountable structure.
As improvement, described housing is cylindric.
As improvement, described ventilating opening is located between cylinder shell and drive motors.
As improvement, described housing is that aluminum alloy materials is made.
As improvement, described housing is that plastics are made.
As improvement, control module is also provided with the fin for increasing heat dispersion.
Can find out that the utility model tool has the following advantages according to such scheme: control module is adopted packaging shell, control module after encapsulation is arranged in power tool body, because surface of shell is smooth or prolong the radially-arranged projection of housing because outer surface is provided with for what increase air contact surfaces, windage can be reduced further, simultaneously without the need to arranging ventilating opening at power tool body rear, only need be provided with ventilating opening at housing place, now extraneous air only need prolong ventilating opening and enters power tool body between drive motors and housing, thus effectively utilize wind path to circulate.
