Electric hand drill convenient for heat dissipation

Abstract

The utility model discloses an electric hand drill convenient for heat dissipation, and relates to the technical field of electric hand drills, the electric hand drill comprises a drill shell, a drill bit part, a rotor part and a stator part, the outer side of the drill shell is provided with a second heat dissipation hole and a first heat dissipation hole, and the stator part is installed at the middle position of the drill shell; the electrified rotor part rotates under the action of a magnetic field of the stator part, so that the fan wheel is driven to rotate, outward wind speed is generated, heat in the middles of the rotor part and the stator part is conveyed to the first heat dissipation holes, and the heat enters the transfer bin along with air and is distributed into the multiple sets of conical pipes; the multiple sets of conical pipes are parallel to one another and point to the front of the drill bit part, then directional wind speed is generated at the working position of the drill bit part, heat at the drilling position is blown away, meanwhile, dust, chippings and the like can be blown away in the direction away from the human body, external air with the low temperature is supplemented into the drill shell from the second heat dissipation holes, and the temperature in the drill shell is lowered.
