Description

TECHNICAL FIELD

[0002] As a basic air conditioning device, the fan realizes the periodic adjustment of the air supply angle through the swing function, significantly improves the uniformity of airflow distribution, and has become a key technology module for improving the use experience in household and commercial environments. The traditional swing mechanism usually adopts a rotating connection structure between the fan head and the support frame to realize the swing function, and a slot design is usually provided on the upper side of the support frame to accommodate the rotating part. Such slot scheme has significant advantages in cost control and batch production adaptability by simplifying the molding complexity of the support frame and reducing material use.

[0003] However, the existing slot structure exposes safety hazards in long-term use: the assembly gap formed by the slot in the connection area between the support frame and the fan head is generally too large, and is further enlarged by mechanical vibration and part wear during the swing movement. When the fan is in the swing working state, the dynamic gap area between the head and the support frame may form a pinch risk point, and if the user's (especially children) fingers accidentally enter this area, there is a safety hazard of being pinched by the moving parts. Such problems are particularly prominent in home scenarios, which seriously restricts the safe use range of the product.

[0004] Therefore, how to effectively avoid the user from being pinched while retaining the low-cost advantage of the slot structure, while ensuring the reliability of the swing mechanism, has become a technical problem that needs to be solved in the field.
