Abstract

The invention discloses a brushless hairdryer with a compact structure, comprising a cylindrical main body, wherein left and right ends of the body are open to form left and right openings; a handle connected to an outer side wall of the body; and a cover connected to the left end of the main body, to close the left opening, wherein, the inside of the cylindrical body is formed with an air duct extending along the axial direction thereof, at least two air inlet holes leading to the air duct are arranged on the cover, a blast chamber and a heating chamber are arranged on the air duct in sequence along the flow direction of the air flow, and the blast chamber is provided with a blast assembly and a PCB assembly sleeving the blast assembly. According to the invention, the annular PCB which can be sleeved on the blower is arranged in the hairdryer, and the problem that the volume of the brushless hairdryer is too large is solved; meanwhile, the air duct inside the brushless hairdryer is reasonably optimized, and the problem that the noise is too large after the volume is reduced is solved, and the brushless hairdryer has wide market application prospect.

Description

technical field [0001] The invention relates to the field of hair dryers, in particular to a brushless hair dryer with a compact structure. Background technique [0002] According to whether the driving motor used by the hair dryer is a brush motor or a brushless motor, it can be divided into a brush hair dryer and a brushless hair dryer. The brushless motor is composed of the main body of the motor and the driver. It is a typical mechatronics product. Since the brushless motor operates in a self-controlled manner, it does not have a separate rotor on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation. With the addition of a starting winding, there will be no oscillation and out of step when the load changes suddenly, but the brushless DC motor also has obvious shortcomings. Because the brushless motor needs to be matched with a larger PCB board, the overall volume of the brushless hair dryer is relatively small. Large,...
