Description

Face warming protection tool in low-temperature environment
Technical Field
The invention relates to the field of wearable, in particular to a face warming protection tool in a low-temperature environment.
Background
The low-temperature weather and the cold wind of the stings often cause people to feel abnormal discomfort when going out, and the protection of the respiratory tract and the face is gradually paid attention to. In order to avoid the damage to respiratory tract caused by direct inhalation of cold air, people often wear protective devices such as masks, face guards, head covers and the like. The commercial products can play a certain role in slowing down heat conduction and convection heat dissipation brought by cold environment and cold air, but the commercial products are quite limited in effect due to the fact that the commercial products do not have the capability of efficiently regulating and controlling basic heat dissipation physical quantity, and other additional performances besides weak heat retention performance cannot be considered. For example, the warm-keeping head cover often has unsmooth breathing and cannot be applied to scenes such as sports; products with good ventilation are often realized by directly opening at the mouth and nose, so that the products cannot buffer and heat cold air to a certain extent, and therefore, only a certain protection effect can be provided for facial skin, and the injury of cold air to the respiratory tract cannot be avoided.
In summary, the technology of the existing equipment is still in a blank state, and the problem of preventing the cold air from damaging the respiratory system and the contradiction of oxygen inhalation amount during strenuous exercise are not solved yet. The face protection with both heat preservation and ventilation is still lacking, the face is not only kept warm in a severe cold environment, but also has a specific and enough breathing channel, and the cold air is heated and then sent into the respiratory tract while sufficient oxygen supply is provided. The device can be applied to sports scenes of high-strength exercises, daily trips of ordinary people, duty stops of special industries and the like, and has wide application potential.
