An electric drill capable of dust absorption and shock absorption

Abstract

The invention discloses an electric drill capable of absorbing dust and reducing vibration and belongs to the technical field of electric machinery. The electric drill comprises a drill bit, a drill body, a handle and a dust absorption device which are connected with one another, and the dust absorption device is connected with the drill body. The dust absorption device comprises a dust collection box, a dust absorption pipe connected with an inlet of the dust collection box, a first filtering mesh and a pressure sensor, wherein the first filtering mesh is arranged in the dust collection box and is away from one end of the dust absorption pipe, and the pressure sensor is arranged on the outer surface of the dust absorption pipe; the end, away from the dust collection box, in the dust absorption pipe is provided with a draught fan for sucking dust, and the end, correspondingly provided with the first filtering mesh, of the dust collection box is provided with an outlet; the dust collection box is furthermore internally provided with a cavity with a flip cap, and the cavity is internally provided with a controller connected with the pressure sensor; and the drill body is furthermore internally provided with a vibration reduction mechanism. By means of the electric drill, the phenomenon of flying dust in the work process of the electric drill can be effectively prevented, the dust absorption device in the electric drill can also be controlled intelligently to move along a sliding rail, and thus the situation that the dust absorption pipe in the dust absorption device is excessively pressed by the wall or the ground and damaged is prevented.

Description

technical field [0001] The invention relates to the technical field of electric machinery, in particular to an electric drill capable of dust absorption and shock absorption. Background technique [0002] The electric drill is a drilling tool that uses electricity as power. The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works, and drives the operating device through the transmission mechanism to drive the gear to increase the power of the drill bit. So that the drill bit scrapes the surface of the object and penetrates the object better. Electric drills are widely used in the reinforcement of building beams, plates, columns, walls, etc., and the installation of decoration, wall installation, brackets, railings, billboards, air-conditioning outdoor units, guide rails, satellite receiver elevators, steel structure workshops, etc. [0003...

AI Technical Summary

Problems solved by technology

[0003] Because the electric drill has the advantages of being cheap and easy to carry, it is well received by workers in the hardware and decoration industries. However, due to the vibration of the internal motor and manual operation and other factors during the existing electric drill electric drilling process, it is easy to cause the drill bit to move. , so that there is a small range of deviation in the drilled hole, resulting in low drilling accuracy

And existing electric drill generally can appear dusty phenomenon in drilling process, and this has not only increased the dust amount of surrounding air, polluted air, has also brought influence to worker's physical and mental health

At the same time, the electric drill will emit a lot of noise during the drilling process, which brings a lot of noise pollution
