Embodiment Construction

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0036] The blowing device disclosed in the present invention, on the one hand, optimizes the design of the air duct structure to reduce noise and increase the air intake, and on the other hand, isolates the heating module 30 from the control module 40 to avoid residual temperature of the heating module 30 The damage caused to the control module 40 improves the service life.

[0037] combine figure 1 with figure 2 As shown, the blowing device disclosed by an embodiment of the present invention includes a housing 10 , a fan 20 , a heating module 30 and a control module 40 . Wherein, the casing 10 is a hollow structure, which is T-shaped as a whole, and includes a blower part 11 and a handle part 12 . The air duct 11 is provided with a first air duct 111 extending in the axial direct...

Abstract

The invention discloses an air blowing device which comprises a shell, a fan, a heating module and a control module. The shell comprises an air duct part and a handle part, the air duct part is provided with a first air duct and an air duct air outlet and an air duct air inlet which are communicated with the first air duct, the handle part is provided with a second air duct and a handle air inlet communicated with the second air duct, and the second air duct is communicated with the first air duct; the fan is assembled in the first air duct and located between the air duct air outlet and the air duct air inlet; the heating module is assembled in the first air duct and is positioned at the downstream of the fan; and the control module is assembled in the second air duct, electrically connected with the fan and the heating module and used for enabling the fan and the heating module to work. A noise can be reduced, the air inlet amount can be increased, and meanwhile the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of hair dryers, in particular to a hair dryer. Background technique [0002] Hair dryer is an essential household electrical appliance in daily life, and it is mainly used for drying and shaping of hair. At present, a hair dryer mainly includes a casing, a motor, fan blades, a heating element and a control module. When the hair dryer is working, it relies on the motor to drive the fan blades to rotate. During the rotation of the fan blades, air is sucked in from the air inlet and heated by the heating element, and then blown out from the air outlet. With the application of small-sized brushless high-speed motors, hair dryers are also developing towards miniaturization and portability. However, as the size of the blower decreases to a certain extent, the air intake area of ​​the original air duct structure will be correspondingly reduced in a limited space. On the one hand, it is easy to make the air intake...
