Problems solved by technology

[0003] Taking the existing floor fans as an example, most of the existing floor fans are in the mode of one motor plus blades, which leads to the fact that the fan can only blow air to a narrow area in front of the fan during operation.
For the fan with shaking head mode, although it can change the blowing direction, there are some places where the fan is not facing during the shaking head process, resulting in no wind blowing in these places, causing great inconvenience

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] The present invention proposes a fan, such as figure 1 As shown, an embodiment of the fan 100 in the present invention includes: a frame 110, at least two fan blade assemblies 120 arranged in the frame 110, the frame 110 is provided with air outlets corresponding to the fan blade assemblies (not marked ); wherein, at least one of the at least two blade assemblies 120 is provided with an angle adjusting device for adjusting its angle. In this way, by adjusting one of the fan blade assemblies 120 or adjusting the angles of two or all fan blade assemblies 120 (in the case that multiple fan blade assemblies are provided with angle adjustment devices), the air supply area of ​​the entire fan 100 can be adjusted. Size or position, its adjustment flexibility and variability are stronger.

[0030] In this embodiment, each fan blade assembly 120 include...

Abstract

The invention discloses a fan and a control method thereof. The fan comprises a frame and at least two fan blade assemblies, wherein the fan blade assemblies are arranged in the frame; the frame is provided with air outlets corresponding to the fan blade assemblies; and at least one of the fan blade assemblies is provided with an angle adjusting device adjusting the angle of the fan blade assembly. By adjustment of one of the fan blade assemblies or two of the fan blade assemblies or all the fan blade assemblies, the size or position of the air supply area of the whole fan can be achieved, andthe flexibility and variability of the adjustment are high.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a fan and a control method thereof. Background technique [0002] A fan is an electrical appliance used for cooling. It can be used to cool down people in daily life, and it can also be used to cool down special equipment. [0003] Taking the existing floor fans as an example, most of the existing floor fans are in the mode of a motor and blades, which leads to the fact that the fan can only blow air to a narrow area in front during the operation of the fan. As for the fan with the shaking head mode, although the blowing direction can be changed, there are some places where the fan does not face in the shaking head process, causing these places to have no wind to blow, causing great inconvenience. Contents of the invention [0004] The object of the present invention is to provide a fan and its control method to improve the variability of the air supply area of ​...
