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.
Claims19
A neck fan, configured to be worn around a neck of a user, comprising:
- an outer shell, configured to hang around the neck and defining an accommodating space inside the outer shell;
- a centrifugal fan, received in the accommodating space;
- the centrifugal fan comprising:
- a plurality of blades, wherein the plurality of blades are configured to rotate to intake air from an outside of the centrifugal fan to generate wind;
- and
- a vortex tongue structure, arranged in the accommodating space and comprising a pressurizing plate and a wind guiding plate connected to the pressurizing plate, wherein the pressurizing plate is a curved wall arranged around ends of some of the plurality of blades, the wind guiding plate protrudes from and is extending away from an outer surface of the pressurizing plate;
- wherein the wind guiding plate defines a wind guiding channel along which the wind is flowing;
- and a cavity is defined between an outer surface of the vortex tongue structure and an inner wall of the outer shell to isolate noise generated by the centrifugal fan from the user.
A neck fan, configured to be worn around a neck of a user, the neck fan comprising:
- an inner shell, disposed near the neck and defining a plurality of air outlets;
- an outer shell, connected to the inner shell and disposed opposite to the inner shell and away from the neck, wherein the outer shell and the inner shell cooperatively define a receiving channel;
- two centrifugal fans, wherein one of the two centrifugal fans is disposed at an end of the receiving channel, and an other one of the two centrifugal fans is disposed at an other end of the receiving channel, wherein the receiving channel is communicating with the plurality of air outlets;
- a partition, received in the receiving channel and dividing the receiving channel into a first channel and a second channel, wherein the second channel is configured to receive electric components of the neck fan;
- wherein each of the two centrifugal fans is configured to generate wind and drive the wind to flow into both the first channel and the second channel, and/or a portion of the inner shell that contacts the neck of the user extending upwardly to form a curved surface, the curved surface may be inclined at a certain angle relative to the portion that contacts the neck of the user, and the plurality of air outlets are defined in the curved surface, such that the plurality of air outlets are oriented towards an inner side of a tubular body portion;
- and
- each of the two centrifugal fans comprises:
- a plurality of blades, wherein the plurality of blades are configured to rotate to intake air from an outside of the centrifugal fan to generate the wind;
- and
- a vortex tongue structure, comprising a pressurizing plate and a wind guiding plate connected to the pressurizing plate, wherein the pressurizing plate is a curved wall arranged around ends of some of the plurality of blades, the wind guiding plate protrudes from and is extending away from an outer surface of the pressurizing plate.
A neck fan, comprising:
- an outer shell, configured to hang around a user neck and defining a receiving space;
- a vortex tongue assembly, received in the receiving space and comprising a vortex tongue shell and a centrifugal fan disposed inside the vortex tongue shell;
- wherein a cavity is formed between an outer surface of the vortex tongue shell and an inner wall of the outer shell and is configured to absorb noise generated by rotation of the centrifugal fan.
