Abstract text

An adjuster for facemask comprising a lamellar structure and a plurality of stabilizing pillars on the lamellar structure, which each stabilizing pillar is comprised of a stabilizing piece installed in a stabilizing groove. When users wear facemasks, they insert ear-loops extending from one side of the facemask into the stabilizing groove of the respective-side stabilizing pillar on the lamellar structure, to be held fixed in the lamellar structure by respective stabilizing piece. Afterwards, the user places the adjuster to the back of the head and inserts the other ear-loops into their respective stabilizing grooves on respective stabilizing pillars to be held fixed by their respective stabilizing piece. Hence, the ear-loops are tucked to the bottom of the stabilizing groove of stabilizing pillar due to a pulling-force, and the facemask becomes firmly held fixed by the adjuster, wrapping around the head, which for this reason air leakage is reduced and security is heighten. Moreover, the facemask is also improved with increased comfort, by allowing user to adjust tightness on-demand.
