Dust collecting device for electric tool

Abstract

The invention discloses a dust collecting device for an electric tool, and belongs to the technical field of electric machines. The dust collecting device includes a dust collecting box, a dust collecting tube connected with the air inlet of the dust collecting box, and a first filter screen arranged at one end, far from the dust collecting tube, in the dust collecting box, the periphery of the first filter screen is abutted against the inner wall of the dust collecting box, and an air outlet is arranged at one end, correspondingly provided with the first filter screen, of the dust collecting box; the periphery of the tube orifice of one end, far from the dust collecting box, of the dust collecting tube, is connected with a dust shield, and a fan is arranged at one end, far from the first dust collecting tube, in the dust shield; an alarm is arranged outside the dust collecting box, a sensor and a chamber are arranged in the dust collecting box, the sensor is arranged at the upper portion of the dust collecting box and at one side, far from the air inlet, of the dust collecting box, and a controller connected with the alarm, the sensor and the fan is arranged in the chamber; and the dust collecting box is connected with an electric tool body. The dust collecting device can effectively prevent the dust flying phenomenon in the working process of the electric tool, and also can prevent the influences of excessive dusts in the dust collecting box on the dust collecting effect.

Description

technical field [0001] The invention relates to the technical field of electric machinery, in particular to a dust collection device for electric tools. Background technique [0002] Existing electric tools such as electric drills and cutting machines generally appear dusty during the working process, often accompanied by the appearance of a large amount of dust, which not only increases the amount of dust in the surrounding air, pollutes the air, but also harms the operators. impact on physical and mental health. If the protective cover is not worn, the inhalation of dust will seriously affect the health of the operator. But if you wear a protective cover, it will more or less affect the operator's line of sight. Therefore, there is an urgent need to develop a dust collection device that can fully absorb the dust generated during the working process of such electric tools. air effect. At the same time, electric tools also emit a lot of noise during the working process, ...

If the protective cover is not worn, the inhalation of dust will seriously affect the health of the operator

However, if you wear a protective cover, it will more or less affect the operator's line of sight

Therefore, there is an urgent need to develop a dust collection device that can fully absorb the dust generated during the working process of such electric tools. air effect

At the same time, electric tools will emit a lot of noise during the working process, which brings about a lot of noise pollution.
