Abstract

The invention provides an air outlet device. The air outlet device comprises a hub; the fan blades are arranged on the hub, and the fan blades are arranged in a double-end symmetrical wing shape. The fan blades are arranged to be in a double-end symmetrical wing shape, so that when the fan blades are driven by external force to rotate in different rotating directions, the symmetrically-arranged fan blades are the same in blade shape in different windward directions, it is guaranteed that the pneumatic states of the fan blades are the same when the fan blades rotate forwards and backwards, and the air outlet amount of the two sides of the hub is effectively balanced when the fan blades rotate forwards and backwards; and the blowing requirements can be met in two directions during forward and reverse air outlet.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an air outlet device. Background technique [0002] At present, most of the fans on the market are single-direction air supply. Single-layer or double-layer fan blades are generally used. The blowing range is wide, and the wind blown is soft and comfortable. With metal or plastic mesh covers, it can achieve blowing and cooling. It is popular among consumers. favorite. [0003] Nowadays, the main way to increase the blowing range of the fan is to set up an oscillating device, but when only the opposite two directions need to receive wind, this setting will slow the change of the blowing range, and additional structures will be required to increase the cost of the device. In the prior art , the two-way switching of the fan can be realized by changing the forward and reverse rotation of the fan blade, thereby meeting the demand for two-way air outlet. However, in the prior art, during...
