Abstract

The invention provides a blowing-suction device. The blowing-suction device comprises a casing, a motor and a main fan. The casing is provided with a first air inlet-outlet terminal and a second air inlet-outlet terminal, the first air inlet-outlet terminal is communicated with the second air inlet-outlet terminal; the motor is installed in the casing, the motor is provided with a first air inlet-outlet port and a second air inlet-outlet port, the interior of the motor is provided with an inner air duct, the inner air duct is communicated with the first air inlet-outlet port and the second air inlet-outlet port, the first air inlet-outlet port is communicated with the first air inlet-outlet terminal, the second air inlet-outlet port is communicated with the second air inlet-outlet terminal; the main fan is installed on the output shaft of the motor, wind can drive heat generated by the motor to be discharged out of the motor through the first air inlet-outlet port or the second air inlet-outlet port, then the heat is discharged out of the casing through the first air inlet-outlet terminal or the second air inlet-outlet terminal, the motor can be cooled, heat dissipation of the motor can be accelerated, the motor cannot be burnt out, the service life of the motor is prolonged, and the performance of the blowing-suction device is guaranteed.

Description

technical field [0001] The invention relates to the field of air blowing and suction equipment, in particular to a blowing and suction equipment. Background technique [0002] At present, for the axial-flow hair dryer, when the hair dryer is working, the motor will generate a large amount of heat, and the heat will be discharged through the air duct between the motor and the housing of the hair dryer to realize heat dissipation and cooling of the motor. However, the effect of only using the air duct between the motor and the housing of the hair dryer to dissipate heat is not very good, which will lead to untimely heat dissipation, excessive temperature rise of the motor, and easy burnout of the motor, affecting the use of the hair dryer. Contents of the invention [0003] Based on this, it is necessary to provide a blowing and sucking device capable of ensuring the cooling effect of the motor therein for the problem of poor cooling effect of the motor in the current blowin...
