Title:
AIR-INLET GRILLE ASSEMBLY, APPLIANCE BODY, AND HAIR CARE APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2023/109494
Kind Code:
A1
Abstract:
An air-inlet grille (31) assembly, an appliance body, and a hair care appliance, relating to the technical field of hair care appliances. The air-inlet grille (31) assembly comprises an air-inlet grille (31) covering an air-inlet end (101) and provided opposite to an impeller (22). The air-inlet grille (31) can prevent most external impurities from entering the appliance body along with an airflow through the air-inlet end (101), and particularly can prevent most of hair from passing through the air-inlet end (101). Furthermore, the air-inlet grille (31) assembly further comprises an extension member (32). The extension member (32) is provided on the air-inlet grille (31) and extends to the impeller (22) along the rotation axis of the impeller (22). In this way, when the hair care appliance works, the impeller (22) drives an airflow to enter the appliance body from the air-inlet grille (31) through the air-inlet end (101), so that a strong rotating vortex can be formed in the circumferential direction of the extension member (32); in this case, if a small amount of hair is sucked into the appliance body, the hair can be wound on the extension member (32) under the action of the rotating vortex. In addition, the configuration of the extension member (32) can further weaken the central area of the rotating vortex to reduce suction force for hair, thereby reducing the amount of sucked hair.
