Abstract
A portable air purifier may include an inlet configured to form a path along which air is suctioned, a filter disposed at an upper side of the inlet and configured to purify air which enters through the inlet and moves upward, a sanitizing portion disposed at a lower side of the filter, installed at a height allowing the sanitizing portion to overlap the inlet, and configured to irradiate sanitizing light toward the filter, and a fan module disposed at an upper side of the filter and configured to rotate a fan to blow air in a direction toward the upper side of the filter.
Claims34
A portable air purifier, comprising:
- an inlet configured to form a path along which air is suctioned;
- a filter disposed at an upper side of the inlet and configured to purify air which enters through the inlet and moves upward;
- a sanitizing portion disposed at a lower side of the filter, installed at a height allowing the sanitizing portion to overlap the inlet, and configured to irradiate sanitizing light toward the filter, wherein the sanitizing portion includes:
- an irradiating portion disposed on a vertical reference line, which passes through a center of the inlet in a vertical direction, and configured to irradiate sanitizing light toward the filter;
- a sanitization support disposed at a lower side of the irradiating portion;
- and
- a pedestal that protrudes to an upper side of the sanitization support to support the lower side of the irradiating portion, the pedestal overlapping the inlet;
- and
- a fan module disposed at an upper side of the filter and configured to rotate a fan to blow air in a direction toward the upper side of the filter.
