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.

A neck fan, configured to be worn around a neck of a user, includes: an inner shell, disposed near the neck; 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 space; a plurality of fan assemblies. Each fan assembly is received in the receiving space and connected to the inner shell and the outer shell. Each of the inner shell and the outer shell defines a plurality of air inlets, each fan assembly corresponds to both the air inlets in the inner shell and the air inlets in the outer shell, each of the plurality of fan assemblies is configured to intake air from an outside of the neck fan into the receiving space through the corresponding plurality of air inlets.

A neck fan includes an arc-shaped shell configured to hang around user's neck and at least four fan assemblies arranged in the shell. The shell includes a first part and a second part. Each of the first part and the second part defines an accommodating space, air inlets and air outlets communicated with the accommodating space, at least one partition is arranged in the accommodating space and configured to divide the accommodating space into at least two accommodating parts arranged along an extension direction of the shell. Each of the fan assemblies is arranged in one of the at least two accommodating parts and is configured to direct air into the one of the at least two accommodating parts through corresponding air inlets and to direct air out of the one of the at least two accommodating parts through corresponding air outlets.

Certain aspects are directed to a portable and wearable cooling and heating device configured to regulate temperature by blowing cool or warm air that is transferrable, light weight, flexible, and retractable. The device comprises a first support arm, a second support arm, and a control module that is preferably battery powered configured to control the speed of air flow. The first and second support arm each further comprises an air canal with a plurality of air outlets, temperature packs, insulation pads, a housing configured to receive an air flow supplier, an air flow supplier nozzle that directs and enhances the air flow, an air flow barrier that prevents air from reentering the air flow supplier. Additionally, the first and second support arms of the wearable cooling and heating device are further provided with at least one Peltier device to optimize the air temperature and an aromatherapy chamber.

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.

Provided is a headgear including first and second holding parts that respectively hold first and second cooling members. In a worn state, the first and second holding parts are respectively positioned laterally to left and right carotid arteries. The headgear includes a headgear main body to be worn on a head and a neck cover that covers a neck, the first and second holding parts are provided in the neck cover, the first holding part is a first pocket that stores the first cooling member, the second holding part is a second pocket that stores the second cooling member, and the headgear includes a coupling part that detachably couples a left end part and a right end part of the neck cover.

A health care device includes a soft water bag, a control unit disposed on a side of the soft water bag, a temperature control element electrically connected to the control unit and disposed inside the soft water bag. When the control unit controls the temperature control element, the temperature control element disposed inside the soft water bag is energized to heat and control a temperature of liquid in the soft water bag, so as to provide better portability than the conventional products.

A portable blowing device includes a body and fans arranged in the body. Air channels are arranged in the body and extend in the length direction of the body to allow airflow to pass through. Wind shields are arranged in the air channels, and a periphery of the wind shield is closely connected with a side wall of the air channel so that a sub-air channel is formed between the wind shield and the side wall of the air channel. Air outlets are formed in the side wall for communicating with outside and the sub-air channel, and airflow generated by the fan can enter the sub-air channel and then exits the air outlets. Because of the reduced volume of the sub-air channel, the airflow is concentrated after entering the sub-air channel, and airflow exiting the air outlets is strengthened, so that the cooling effect and the user experience are improved.
