Title:
NECK HANGING TYPE COOLING AND HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/151621
Kind Code:
A1
Abstract:
A neck hanging type cooling and heating device, comprising an arc-shaped neck hanging body. Cold and heat generators are provided on the neck hanging body; each cold and heat generator comprises a conduction member, a cold and heat semiconductor, a diffusion member, and a fan assembly; the fan assembly is provided on the side of the diffusion member away from the cold and heat semiconductor; the side surface of the diffusion member facing a fan extends upwards to form a plurality of diffusion wings; the diffusion wings are arranged at intervals to form a ventilation groove; groove openings on the two ends of the ventilation groove are formed in the length direction of the neck hanging body; the peripheral housing of each cold and heat generator are provided with air outlets at the positions of the groove openings at the two ends of the ventilation groove; the air outlets are arranged in the direction away from the neck of a human body; and the housing is provided with air inlets at the position of the fan assembly. According to the present utility model, the improved design for the structure achieves the switching of double-layer functions of cooling and heating, and the structure for discharging hot air or cold air is also reasonable, such that the discharged air does not react on a human body, the use experience of a product is effectively enhanced, and the discharging efficiency is high.
