Problems solved by technology

[0003] In related technologies, the axial flow fan controls the fan's air outlet speed through high and low gears. When the axial flow fan works in high-grade mode, the noise is high, which will cause users to complain. In addition, the axial flow fan increases the blowing area by shaking the head left and right.

Abstract

The invention discloses an air supply device which comprises a volute provided with an air inlet and an air outlet. The air supply assembly is arranged in the volute; and the driving device is arranged to be used for driving the volute to rotate around a set axis, and the set axis penetrates through the air outlet, so that the air outlet can circumferentially rotate around the set axis. Therefore, through cooperative work of the volute, the air supply assembly and the driving device, when the volute rotates around the set axis, the air supply device can blow out soft surrounding air, the feeling comfort of blown air can be improved, and when the volute does not rotate, the air supply device can blow out low-noise and strong straight air, and rapid cooling can be achieved; therefore, air blown by the air supply device can be switched between low-noise strong straight air and soft surrounding air, a user can select the air outlet mode of the air supply device at will according to use requirements, the problem that the noise of an axial flow fan is high can be solved, and the problem that the user is headache due to air blown by a centrifugal fan can also be solved.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to an air supply device. Background technique [0002] Most of the existing fans are divided into axial flow fans and centrifugal fans. When the ambient temperature is relatively high, high wind speed is required to quickly cool down, and when the ambient temperature is low, gentle wind is required to cool off. [0003] In the related art, the axial fan controls the blowing speed of the fan through the high and low gears. When the axial fan operates in the high-end mode, the noise is high, which will cause users to complain. Moreover, the axial fan increases the blowing area by shaking its head left and right. The centrifugal fan is basically strong straight wind, which can effectively and quickly cool down, and it is easy to cause headaches for users after long-term use. From this, it can be seen that the axial flow fan and the centrifugal fan have their own shortcom...
