Description

A blower capable of controlling air volume

Technical Field

The utility model relates to the technical field of blowers, in particular to a blower capable of controlling air volume.

Background Art

The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (also oil tank), and oil drip nozzle. The blower operates eccentrically with the offset rotor in the cylinder, and the volume change between the blades in the rotor slot causes the air to be sucked in, compressed, and exhaled.

According to a blower disclosed in the patent network (authorization announcement number: CN218934784U), "The utility model discloses a blower, comprising: a fan casing, the fan casing is internally provided with fan blades for rotation, the fan casing has a blast inlet and a blast outlet; a blower motor is arranged outside the fan casing, and the casing of the blower motor is fixed on the fan casing, the blower motor is an outer rotor motor, the rotor of the blower motor is connected to the fan blades, a protective cover is arranged on the outside of the blower, and a controller is also arranged on the same side as the blower motor.
