A DUST PROOF AND ANTI-GAS MASK

摘要

The present invention relates to a dust proof and anti-gas mask and, more specifically, to the dust proof and anti-gas mask which comprises: a filter accommodating unit in which a plurality of hooking rings is formed in one side; and a filter which is interlocked with the filter accommodating unit. The filter comprises: projecting parts formed on one outer periphery in order for the projecting parts of the filter accommodating unit to be settled; a plurality of projecting rings formed on the other end part; filter cases formed on the inner surface in which filter materials are filled; and filter materials filled in the inner space of the filter cases. The present invention improves connection structures of the plurality of filters connected to the dust proof and anti-gas mask so that attachment and detachment of each filter can be facilitated and prevents damage risks of each filter during use of the dust proof and anti-gas mask by firmly connecting each filter. Besides the above characters, the present invention drastically enhances an air purification function for air which enters and exits the mask by controlling the number of filters based on surrounding condition.
