Patent number: 11333391Abstract: The present disclosure relates to an air port component and an air conditioner, wherein the air port component includes a first plate body and a second plate body, wherein two longitudinal ends of the first plate body and the second plate body are elastically connected respectively. When the working environment temperature difference is relatively large, even if the difference between the linear expansion coefficients of materials used by the two plate bodies is relatively large, extension or shrinkage generated between the plate bodies due to temperature changes is be compensated by the elastic connection so as to reduce the degree of plastic deformation of the plate bodies due to temperature changes after being used for a period of time, thereby improving the reliability of the operation of the air port component, preventing blockage during the operation, as well as ensuring that the airflow of the air outlet meets the design requirements to prevent condensation due to local overcooling.Type: GrantFiled: August 24, 2018Date of Patent: May 17, 2022Assignees: Gree Electric Appliances (Wuhan) Co., Ltd., Gree Electric Appliances, Inc. of ZhuhaiInventors: Xiaolong Chi, Jingzhong Zhuang
