Patent number: 11800918Abstract: The present disclosure provides a blow dryer. The blow dryer includes an air duct and a handle coupled to the air duct. The air duct arranges an air outlet channel and an air outlet in air communication with the air outlet channel. The air duct is provided with an air guiding element at a front end of the air outlet channel. The air guiding element is configured to guide airflow in the air outlet channel to an inside wall of the air outlet channel, so that the airflow is concentrated and discharged from the air duct through the air outlet, thus increasing the strength of the wind pressure provided by the blow dryer.Type: GrantFiled: June 16, 2022Date of Patent: October 31, 2023Assignee: SHENZHEN CARKU TECHNOLOGY CO., LIMITEDInventors: Yun Lei, Chuwei Liu, Yubin Zhang

Patent number: 11533975Abstract: The present disclosure provides a hair dryer, including an air duct and an air nozzle. The air nozzle includes an air nozzle housing defining an air outlet channel and a first adsorbing member. A first end of the air outlet channel is in air communication with an air outlet of the air duct. The first adsorbing member is arranged on the air nozzle housing close to the first end. A second adsorbing member is arranged on the air outlet. The second adsorbing member is arranged around the air outlet. The air nozzle is detachably coupled to the air outlet by adsorption, thus simplifying the installation of the air nozzle, facilitating the installation and replacement of the air nozzle, and thereby improving the user experience. The first adsorbing member is matched with the second adsorbing member to allow the air nozzle housing to be positioned on the air duct.Type: GrantFiled: May 12, 2021Date of Patent: December 27, 2022Assignee: Shenzhen Carku Technology Co., LimitedInventors: Yun Lei, Chuwei Liu, Yubin Zhang
