Description

Technical Field

[0001] The present invention relates to the field of air conditioning equipment, in particular to a seat with a fan and an air flow component. Background Art

[0002] In the prior art, there are precedents for structural designs of "applying a fan function to a human body device so that a user can enjoy the wind blown out by the fan thereon when using the human body device".

[0003] For example, the Chinese utility model patent CN202959602U discloses an electric fan chair, which includes a chair leg, a backrest, an armrest and a seat; the edges of the armrest and the backrest are formed by winding a hollow tube in one piece, and a plurality of air outlet holes are formed on the tube wall of the hollow tube. A tubular electric fan and a power plug are provided under the seat, and the tubular electric fan and the power plug are connected by a power cord, and the tubular electric fan blows air into the hollow tube. Although this chair can realize the fan function, it has the following defects:

[0004] On the one hand, it has multiple air outlet holes on the tube wall to blow air outwards, and the wind blown out is scattered, unconcentrated, uneven, and cannot be blown far. The wind feeling felt by the human body is not obvious, and the user experience is poor. On the other hand, it uses an ordinary tubular electric fan to blow air into the hollow tube body, and the wind pressure is insufficient. In actual use, it is difficult to effectively pump the external air flow to various parts of the integrally wound hollow tube body. It is easy for the part close to the tubular electric fan to have a larger air volume, while the part far away from the tubular electric fan has a smaller or even no air volume, resulting in uneven air volume and a small coverage area.
