Heat exchange type antibacterial and dustproof mask

Abstract

The invention relates to a heat exchange type antibacterial and dustproof mask. The heat exchange type antibacterial and dustproof mask is characterized in that inner and outer surfaces of the mask are made of antibacterial materials or textile fabrics, foam metal prepared according to certain technical parameters is filled between inner and outer layers, the foam metal with an all-through-hole characteristic has high specific surface area, low density, a certain antibacterial function and excellent thermal storage capacity, and air in the mask is filtered through a filter layer before entering a human body, so that a function of removing harmful particulate matters from air by filtration can be well achieved. The heat exchange type antibacterial and dustproof mask is suitable for people taking outdoor activity in chilly winter, especially patients suffering from asthma and respiratory diseases, the temperature of inhaled air is raised to reduce harmful stimulation of cold air to the respiratory tract, harms of the particulate matters in air are reduced, and humidity of respiratory gas is increased to kill pathogenic microorganisms in the respiratory gas so as to realize protection of a mask wearer.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to a mask capable of performing heat exchange to keep warm while filtering harmful substances in the air. technical background [0002] Many people experience symptoms such as itchy nasal mucosa, continuous sneezing, and continuous wheezing when the climate is cold in winter and the air is dry, which not only affects the normal quality of life, but can even be life-threatening in severe cases. The root cause is mainly due to the so-called "cold air allergy", that is, the onset of allergic rhinitis and allergic asthma caused by cold and dry air in winter. When people carry out outdoor activities in severe cold, they will take away the heat and moisture in the body when they exhale, and inhale low-temperature and dry air when they inhale. Dehydration, which is the culprit behind cold air allergies. [0003] In winter, people often wear masks to filter air and maintain body temperature when t...

AI Technical Summary

Problems solved by technology

However, the current commercially available masks usually only consider the function of filtering air pollutants, which can play a very limited role in keeping warm, and cannot meet the needs of cold protection and warmth in outdoor cold conditions.
