SUMMERY OF THE UTILITY MODEL

The utility model provides a saw with a dust removal structure aiming at the problems.

The technical scheme adopted by the utility model is as follows:

the saw with the dust removal structure comprises a body, wherein a saw blade is rotatably mounted on the body, a motor is mounted in the body and used for driving the saw blade to rotate, and the saw is characterized in that a dust collection box is arranged on the body, blades are mounted on the motor, an air inlet of the dust collection box is located on the periphery of the saw blade, and the blades are located at an air outlet of the dust collection box.

In the saw of this mesostructure, through setting up a dust collection box and blade, the blade follows rotates together when the motor rotates, is in the negative pressure state in the dust collection box like this, and the saw bit can be inhaled in the dust collection box at the raise dust that the during operation produced like this, avoids the production of raise dust.

Optionally, the blades include a first blade and a second blade, and the first blade and the second blade are both installed on a rotating shaft of the motor.

The effect that sets up two blades of first blade and second blade is as follows respectively, and the effect of first blade is to dust collection box evacuation for raise dust can get into in the dust collection box, and the effect of second blade is to the motor production blow air current, thereby plays certain cooling effect to the motor.

Optionally, the dust collector also comprises a filter element which is arranged in the dust collecting box.

The filter element is arranged to filter dust, so that the dust is prevented from entering the blade to block the blade.

Optionally, a gear is installed in the body, and the motor and the saw blade are matched together through the gear.

The function of the gear is to drive the saw blade to rotate.

Optionally, the body is provided with two holding portions.

The two holding parts are arranged to facilitate the holding of an operator.

Optionally, the two grips are perpendicular to each other.

The two holding parts are perpendicular to each other to increase the stability when the operator grips the holding parts.

Optionally, the body is provided with a retaining ring.

Optionally, the body is provided with an arc cover, and the air inlet of the dust collecting box is located at the arc cover.

The air inlet is arranged at the arc cover, so that the dust can be adsorbed as much as possible on one hand, and on the other hand, the dust can be prevented from being accumulated in the arc cover, and the phenomenon that the saw blade is blocked due to the dust in the arc cover in the rotating process is avoided.

The utility model has the beneficial effects that: through setting up dust collection box and blade, the blade then rotates together when the motor rotates, is in the negative pressure state in the dust collection box, and the raise dust that the saw bit produced at the during operation can be inhaled in the dust collection box, avoids the production of raise dust.

Description of the drawings:

FIG. 1 is a schematic diagram of a saw with a dust removing structure;

fig. 2 is a schematic diagram of the positional relationship between the motor and the impeller.

The figures are numbered: 101. a grip portion; 102. an arc cover; 2. a dust collecting box; 201. an air inlet; 202. an air outlet; 3. a saw blade; 4. a retainer ring; 501. a first impeller; 502. a second impeller; 6. a motor; 7. a gear.

The specific implementation mode is as follows:

the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, a saw with a dust removing structure comprises a body, a saw blade 3 is rotatably mounted on the body, a motor 6 is mounted in the body, the motor 6 is used for driving the saw blade 3 to rotate, and the saw is characterized in that a dust collecting box 2 is arranged on the body, blades are mounted on the motor 6, an air inlet 201 of the dust collecting box 2 is located on the periphery of the saw blade 3, and the blades are located at an air outlet 202 of the dust collecting box 2.

In the saw of this mesostructure, through setting up a dust collection box 2 and blade, the blade then rotates together when motor 6 rotates, is in the negative pressure state in dust collection box 2 like this, and saw bit 3 can be inhaled in dust collection box 2 at the raise dust that the during operation produced like this, avoids the production of raise dust.

As shown in fig. 1 and fig. 2, the blades include a first blade and a second blade, and both the first blade and the second blade are installed on a rotating shaft of the motor 6.

Set up the effect of two blades of first blade and second blade respectively as follows, the effect of first blade is to 2 evacuation of dust collection box for raise dust can get into in the dust collection box 2, and the effect of second blade is to 6 production of motor blows the air current, thereby plays certain cooling effect to motor 6.

As shown in the attached figures 1 and 2, the dust collecting box also comprises a filter element which is arranged in the dust collecting box 2.

As shown in fig. 1 and 2, a gear is installed in the body, and the motor 6 and the saw blade 3 are matched together through the gear.

The function of the gear is to drive the saw blade 3 in rotation.
