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.
