Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] An electric drill includes an air tank 1 , an air bag 4 , an air spray head 8 , a collection bin 10 , a drill bit 9 and an electric drill shell 7 . Wherein the drill bit 9 is located at one end of the electric drill shell 7, the motor is placed inside the electric drill shell 7, and the motor drives the drill bit 9 to move; the other end of the electric drill shell 7 is connected to the air bag 4, and one end of the heat conducting strip 5 is placed in the air bag 4, The other end of the heat conduction strip 5 is connected to the drill bit 9, and the air bag 4 is also provided with an exhaust pipe 6. The air bag 4 is also connected to the gas tank 1, and the gas tank 1 is also connected to one end of the gas delivery pipe 2, and the other end of the gas delivery pipe 2 Connected to the air spray head 8, the function of the air tank 4 is to send ...

The invention discloses an electric drill. The electric drill comprises an air tank, an air bag, an air injection head, a material collecting bin, a drill bit and an electric drill shell; the drill bit is arranged at one end of the electric drill shell, a motor is arranged in a accommodating cavity formed by the electric drill shell, and the motor drives the drill bit to move; the air bag is arranged on the outer side of the electric drill shell, and the air bag is connected with the air tank, a heat conduction strip is inserted into the air bag, the other end of the heat conduction strip is connected with the motor or the drill bit, and an exhaust pipe is further arranged in the air bag; the air tank is further connected with an air delivery pipe, the air delivery pipe penetrates throughthe accommodating cavity of the electric drill shell and the tail end of the air delivery pipe extends to the position of the drill bit, and the tail end of the air delivery pipe is provided with theair injection head. The electric drill has the beneficial effects that the heat conduction strip can reutilize the waste heat of the drill bit, the heat is timely conveyed to the air bag so that the air bag can be expanded to be tightly attached to the wall, the air is sprayed out of through the air injection head, the drill bit can be helped to be cooled, chipping can also be blown off, and the generated chippings and the like are collected in the producing process so that secondary pollution can be prevented.
Description
technical field [0001] The invention relates to the field of electric tools, in particular to an electric drill. technical background [0002] An electric drill is a drilling tool that uses electricity as power. It is a regular product in electric tools, and it is also the most demanded electric tool product. Electric drills only have a rotary motion and are especially suitable for drilling holes in materials that require little force, such as cork, metal, brick, tile, etc. The electric drill only relies on the motor to drive the transmission gear to increase the power of the drill bit to rotate, so that the drill bit can scrape through metal, wood and other materials. [0003] Electric drill is a tool commonly used in machinery industry, construction industry and decoration industry for drilling, screwing and screwing. The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor pe...
