Problems solved by technology

[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 of
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.

Embodiment 1

[0033] Such as Figure 1-Figure 3As shown, the embodiment of the present invention is a dust collection device for electric tools, including a dust collection box 1 (the dust collection box 1 is an insulator), connected to the air inlet (not shown in the figure) of the dust collection box 1 The dust suction pipe 2 and the first filter screen 3 arranged in the dust collection box 1 and away from the end of the dust suction pipe 2, the periphery of the first filter screen 3 abuts against the inner wall of the dust collection box 1 An air outlet 4 is opened at one end of the dust collecting box 1 corresponding to the first filter 3 . The nozzle periphery of the end of the dust collection pipe 2 away from the dust collection box 1 is also connected with a dust collection cover 5 with an inner diameter larger than the outer diameter of the nozzle, and the dust collection cover 5 passes through the end far away from the dust collection pipe 2. A cross bar is fixed with fan 6 for su...

Embodiment 2

[0049] This embodiment is the same as that of Embodiment 1 except that the weight composition of the noise reduction material and its preparation method are different from Embodiment 1.

[0050] The noise reduction material in the noise reduction box 18 in this embodiment is mainly made of the following raw materials in parts by weight: 40 parts of rice bran, 30 parts of polyester fiber sound-absorbing cotton, 20 parts of white vermiculite powder, 20 parts of sepiolite powder, light 20 parts of calcium carbonate, 20 parts of glass fiber, 10 parts of mesoporous titanium dioxide, 10 parts of neoprene, 10 parts of polycarbonate and 8 parts of alkyd resin.

[0051] The preparation method of the above-mentioned noise reduction material comprises the following steps:

[0052] (1) Take the above-mentioned raw materials in parts by weight;

[0053] (2) After mixing rice bran, polyester fiber sound-absorbing cotton, white vermiculite powder, sepiolite powder and light calcium carbonat...

Abstract

The invention discloses a dust suction device for an electric tool, which belongs to the technical field of electric machinery. The dust suction device includes a dust collection box, a dust suction pipe connected to the air inlet of the dust collection box, and a first filter screen disposed in the dust collection box and away from one end of the dust collection pipe, and the periphery of the first filter screen abuts against the dust collector. On the inner wall of the dust box, an air outlet is provided at one end of the dust collection box corresponding to the first filter screen; a dust suction hood is also connected to the periphery of the nozzle of the dust suction pipe away from the end of the dust collection box, and the inside of the dust suction hood is far away from the first dust suction. There is a fan at one end of the tube; an alarm is also provided on the outside of the dust collection box, and a sensor and a cavity are arranged in the dust collection box. A controller connected with an alarm, a sensor and a fan is arranged inside; the dust collecting box is connected with the electric tool body. The invention can not only effectively prevent the phenomenon of flying dust during the working process of the electric tool, but also prevent the effect of dust collection from being affected by too much dust in the dust collecting box.

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, ...
