Problems solved by technology

[0002] At present, the blowing machines on the market are mainly AC blowing machines and gasoline blowing machines. When the technicians of our company are developing a new generation of DC blowing machines, they find that the friction between the blades of the blowing machines and the dust There is no place for static electricity to be released, and it usually accumulates to the charged body. When the electrostatic charge reaches a certain level, there is a risk of shocking the user or damaging the electronic components inside the blower

Abstract

The invention discloses a direct-current blower-vacuum. The blower-vacuum comprises a main case, a drive motor, a direct-current power supply, a collecting device and an electrostatic discharge unit, wherein the main case is provided with an air outlet, the drive motor is disposed in the main case, the direct-current power supply is electrically connected with the drive motor, the collecting device is connected with the air outlet, and the electrostatic discharge unit is electrically connected with the drive motor and extends to the air outlet or the inside of the collecting device. According to the blower-vacuum, the electrostatic discharge unit is arranged in the blower, so that gathering of static electricity in the direct-current blower-vacuum can be avoided, electrostatic shocks to users or damage to electronic components inside the blower-vacuum can be further prevented.

Description

technical field [0001] The invention relates to a garden mechanical tool, in particular to a direct current blower with an electrostatic discharge unit. Background technique [0002] At present, the blowing machines on the market are mainly AC blowing machines and gasoline blowing machines. When the technicians of our company are developing a new generation of DC blowing machines, they find that the friction between the blades of the blowing machines and the dust There is no place for static electricity to be released, and it usually accumulates to charged objects. When the electrostatic charge reaches a certain level, there is a risk of electric shock to the user or damage to the electronic components inside the blower. Contents of the invention [0003] In order to overcome the problem of static electricity generated by the DC blower when it is in the state of absorbing foreign matter, the present invention proposes a DC blower with an electrostatic discharge unit, throu...
