Abstract
An ergonomic neck fan comprises two fan shells for wearing around the neck of the user, and a silicone assembly. The interior of each shell is provided with a fan and cavity wall, and each shell comprises a shell body and a shell rear cover. Air guide components are provided inside the shells, and the air guide components cooperate with the cavity walls to divide the interior space of the shell body into an air outlet assembly and a storage cavity. The air outlet assembly comprises a fan cavity for placing the fan, and a horn-shaped air duct. The invention achieves high-speed airflow and efficient transfer, enabling the wind pressure towards the user's face and neck to be stronger and adaptable to different body shapes in outdoor and sports scenarios, allowing the user to be cooled by the wind and providing a better cooling effect and lower noise.
