The invention discloses a pitching structure and an air blowing device. The pitching structure comprises a machine head, a support and a pitching driving part, the support comprises a first split body and a second split body which are arranged in a spaced mode, the machine head is arranged between the first split body and the second split body, the machine head is rotationally connected with the first split body and the second split body respectively, the pitching driving part is used for driving the machine head to rotate relative to the support, and the gravity center of the machine head is located on a rotating axis of the machine head rotating relative to the support. According to the pitching structure, the gravity center of the machine head is located on the rotating axis of the machine head rotating relative to the support, the torque, relative to the rotating axis, of the gravity center of the machine head is not needed to be overcome when the machine head is driven to swing in a pitching mode, and therefore the needed torque is small; and the torque between the machine head and the support is mainly generated by friction force at the connecting position of the machine head and the support, and therefore the power output by the pitching driving part can more smoothly drive the machine head to perform pitching head shaking, pitching head shaking of the machine head is easier to adjust, pitching head shaking of the machine head is smoother, and the use experience of a user can be improved.
Description
technical field [0001] The invention relates to the technical field of blowing devices, in particular to a pitch structure and a blowing device. Background technique [0002] In household appliances, fans are used to cool down and increase indoor air circulation. They have the advantages of low price and convenient use, and are in great demand. As people's requirements for the indoor environment become more and more stringent, the fan is also being continuously improved. Compared with the single-rod support in the center of the machine head, the way of supporting the machine head with two ears can make the machine head have a larger rotation angle and Inlet and outlet area, but in the traditional binaural head support structure, there are defects in the structural design of the pitch and head control, resulting in unreasonable force on the binaural head support structure during the pitch and head shaking process, and there are problems such as unsmooth head shaking. Conten...
