Abstract: A neck fan includes: an outer shell, defining a receiving space, wherein at least portion of the receiving space serves as an air duct; an inner shell, received in the receiving space and connected to an inner surface of the outer shell, wherein the inner surface is facing towards the receiving space; a fan assembly, arranged in the inner shell. The inner shell comprises a wind guide portion communicating with the air duct; a diameter of the wind guide portion is increased in a direction extending from the fan assembly to the air duct. The fan assembly is configured to generate wind flowing along the wind guide portion to enter the air duct of the outer shell.

Abstract: a neck fan includes: a shell, configured to be worn around a neck of a user; a plurality of fan assemblies, arranged inside the shell. The shell comprises a wind outputting region and a wind-free region; each of the plurality of fan assemblies is located in the wind-free region; the wind outputting region defines a plurality of air outlets to output wind generated by the plurality of fan assemblies to an outside of the shell; the wind-free region of the shell is dis-communicated with the outside of the shell.

Abstract: A neck fan includes: a shell, wherein the shell defines an air duct and at least two air outlets; a fan assembly, arranged inside shell and configured to generate wind flowing along the air duct to reach the at least two air outlets; and a wind guide member, received in the air duct and fixed to a wall of the shell. The at least two air outlets comprises a first air outlet and a second air outlet, the first air outlet is disposed between the fan assembly and the second air outlet. The wind guide member is disposed between the fan assembly and the first air outlet and is configured to guide a first portion of the wind to flow towards the first air outlet.

Abstract: A neck fan is provided and is configured to be worn around a neck of a user. The neck fan includes: an outer shell, disposed away from the neck; an inner shell, connected to the outer shell and disposed near the neck, wherein the inner shell and the outer shell cooperatively define a receiving space. A plurality of air outlets are defined in the inner shell.

Abstract: A portable bladeless fan is provided and includes: a housing, a mix-flow fan, and a pressurizing member. The housing has an air inlet portion at a rear side of the housing and an air outlet portion at a front side of the housing. The mix-flow fan is configured to generate an airflow. The pressurizing member is connected to a front portion of the housing and disposed at a front of the mix-flow fan. The pressurizing member includes a pressurizing seat and second blades. The pressurizing seat includes a pressurizing surface that is at least partially increased in a radial direction from the rear side to the front side, the second blades are spaced apart from each other and are arranged on the pressurizing surface. The second blades re-arrange a direction of the airflow and to reduce a noise of the airflow.

Abstract: A neck fan and a fan assembly are provided. The fan assembly includes: a first air guiding assembly, configured to intake air and to generate an airflow; a second air guiding assembly, fluidly communicated to the first air guiding assembly and disposed at a downstream of the airflow generated by the first air guiding assembly. The second air guiding assembly comprises a plurality of static blades, the plurality of static blades are spaced apart from each other having an equal interval, the plurality of static blades are configured to concentrate the airflow and to guide the airflow to continue flowing.

Abstract: A neck fan includes an arc-shaped shell and a fan assembly. The arc-shaped shell is configured to be worn around a neck of a user. The shell has a first side and a second side opposite to the first side. Each of the first side and the second side defines air inlets. At least one of the first side and the second side defines air outlets. The shell further defines a receiving space, and the receiving space includes an air duct communicating with the air inlets and outlets. The fan assembly is received in the receiving space and configured to drive the air to flow from the air inlets of both sides, through the air duct, reaching the air outlets.
