Air supply device and air supply equipment

Abstract

The invention discloses an air supply device and air supply equipment. The air supply device comprises a flow guide structure and a wind wheel structure. The wind wheel structure can rotate relative to the flow guide structure. The wind wheel structure is used for conducting first-stage guiding on air going into the wind wheel structure to form first-stage air. The flow guide structure is used forconducting second-stage guiding on at least one part of first-stage air, so that at least one part of second-stage air formed through second-stage guiding is blown out in the axial direction of the flow guide structure. Thus, t cooperation of the flow guide structure and the wind wheel structure, the air pressure, air speed and air supply capacity of the air supply device can be increased. Compared with the prior art, a motor of the air supply equipment can meet the operation requirement through low-speed rotation so that the assembly precision of the flow guide structure and the wind wheel structure can be reduced, and the production cost of the air supply device can be reduced. Meanwhile, vibration of the air supply device can be reduced, and noise of the air supply equipment can also be reduced.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to an air supply device and an air supply device having the air supply device. Background technique [0002] In the related art, air supply devices are applied to air supply equipment such as tower fans, ceiling fans, and table fans. And the air supply characteristics are different, and they have advantages and disadvantages. In addition, there are also bladeless fans that use the principle of mixed flow, but this kind of fan has low wind pressure and low wind speed. To achieve higher wind pressure and wind speed, only improve the motor. Speed, for example, increasing the speed of the drive motor to 7000rpm or even higher. For high-speed motors, not only is the cost high, but also the noise is high. At the same time, the dynamic balance requirements of the air supply device and the machining accuracy and assembly accuracy need to reach a high level. , which further in...

Problems solved by technology

[0002] In the related art, air supply devices are applied to air supply equipment such as tower fans, ceiling fans, and desk fans. Air supply devices generally include axial flow fans, cross-flow wind wheels, and centrifugal wind wheels. The air supply principle of each air supply device And the air supply characteristics are different, each has advantages and disadvantages. In addition, there are also bladeless fans using the mixed flow principle, but this fan has low wind pressure and low wind speed. To achieve higher wind pressure and wind speed, the motor can only be increased. Speed, such as increasing the speed of the drive motor to 7000rpm or even higher, for high-speed motors, not only the cost is high, but also the noise is large, and the requirements for dynamic balance of the air supply device, machining accuracy, and assembly accuracy must reach a high level , which further increases the cost of
