At the side of the described radiator window body contrary with the bearing of trend of described first extension, be provided with the second extension that the oblique upper to described grid extends;
The edge of the upright projection of described second extension on described radiator window body is on the outer face of adjacent described grid.
At the outer surface of described first extension, be provided with groove; The center line of described groove is parallel with described grid.
The outer face of adjacent described grid is divided into two parts by the edge of described first extension and the upright projection of described second extension on described radiator window body, is respectively extension occlusion part and the non-occlusion part of extension; The area of described extension occlusion part is greater than the area of the non-occlusion part of described extension.
The area of described extension occlusion part is the 3/4-4/5 of described grid outer face area.
Described groove is arranged in the described first extension part relative with described extension occlusion part.
The cross section of described groove is circular arc.
The outer end of described first extension and described second extension is in the same plane, and this plane overlaps with described radiator window body outer surface.
The beneficial effects of the utility model are:
The utility model by arranging extension on the grid of radiator window body, and the upright projection edge of extension is on adjacent grid outer face, like this, the dust of vertical drop, when dropping to electric tool radiator window position, can not enter into electric tool inside because of the stop of extension.
On the other hand, by arranging groove on extension, when there being water to fall within radiator window body, can guide functions being played by groove and flow down from housing, can effectively stop water to enter into electric tool inside.
