Abstract

The invention discloses a dust suction device for an electric cutting tool. The dust suction device comprises the electric cutting tool, wherein the electric cutting tool comprises a saw blade, a saw blade protective cover and a motor which drives the saw blade to rotate; a scrap discharging opening is formed on the tail part of the saw blade protective cover; one end of a motor shaft of the motor is connected with the saw blade through a speed changing box, and the other end of the motor shaft is extended to the tail part of the motor and is connected with fan blades; a dust suction cover is arranged on the tail part of the motor and comprises a dust suction opening and a dust discharging opening; the dust suction opening is connected with the scrap discharging opening through a pipe body; and the dust discharging opening is connected with a dust suction bag through a scrap discharging pipe. The fan blades are arranged on the motor shaft to generate great suction force by lengthening the motor shaft and fully using the characteristic that the rotating speed of the motor shaft is higher than the rotating shaft of the saw blade, so that scraps such as wood scraps, plastic scraps and the like and dust which are generated in the cutting process are sucked into the dust suction bag, the dust removal efficiency is greatly improved, and a complete dust suction rate can reach over 90 percent.

Description

technical field [0001] The invention relates to an electric cutting tool, in particular to a dust suction device for the electric cutting tool. Background technique [0002] At present, common electric cutting tools include miter saws, table saws and compound saws, etc. These electric cutting tools often generate dust such as wood chips and plastic chips during the cutting of workpieces. In the existing electric cutting tools, in order to collect dust such as cutting chips, a chip discharge pipe is generally installed at the tail of the saw blade guard and connected to a dust suction bag, so that the dust generated during the cutting process can enter the dust suction bag . However, this dust removal method only passively collects the dust that is automatically scattered, and the dust removal effect is not ideal. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a dust sucti...
