Description
本发明属于家用电器技术领域，尤其涉及一种智能风扇。The invention belongs to the technical field of household appliances, and in particular relates to a smart fan.
现有的摇头风扇，其可摆动的头部风轮部分，左右摆动的角度和距离固定，无论所在范围内的各个部位需不需要送风，都会按照固定的路径及角度范围摆动送风。当需要对固定点送风时，可以定住风扇，使其不再摆动，当需要大面积送风时，不再定住，使其头部摆动。The existing moving head fan has a swingable head wind wheel portion, and the angle and distance of the left and right swinging are fixed, and the air is oscillated according to a fixed path and an angular range regardless of the need for air supply in each part of the range. When it is necessary to supply air to the fixed point, the fan can be fixed so that it does not swing. When a large area of air is required, it is no longer fixed and its head is swung.
然而当需要小范围送风时，只能设定在摆动模式，对小范围送风，同时也对小范围外的摆动区域全范围送风，这样就会导致需要送风的小范围内始终会有一定的时间送不到风，不仅效能下降，而且浪费资源。However, when a small range of air supply is required, it can only be set in the swing mode to supply air to a small range, and also to supply a full range of the swing area outside the small range, which will result in a small range in which the air supply is required. There is a certain amount of time to get the wind, not only the performance is reduced, but also the waste of resources.
