Abstract
A portable air purifier is provided that may include a housing having an inlet forming a passage through which air is suctioned into the housing, a filter disposed at an upper side of the inlet and configured to purify air suctioned in through the inlet and flowing upward, an irradiator disposed at a lower side of the filter, installed at a height at which the irradiator overlaps the inlet and configured to irradiate light for sterilization onto the filter, and a sterilizer support configured to support the irradiator and configured to be fixed to the housing and disposed around an outer perimeter of the irradiator.
Claims21
A portable air purifier, comprising:
- a housing having an inlet forming a passage through which air is suctioned into the housing;
- a filter disposed at an upper side of the inlet and configured to purify air suctioned in through the inlet and flowing upward;
- an irradiator disposed at a lower side of the filter, installed at a height at which the irradiator overlaps the inlet and configured to irradiate light for sterilization onto the filter;
- and
- a sterilizer support configured to support the irradiator and configured to be fixed to the housing and disposed around an outer perimeter of the irradiator, wherein the irradiator comprises:
- a printed circuit board supported by the sterilizer support and disposed at the lower side of the filter;
- and
- a sterilizing light source disposed on the printed circuit board and configured to irradiate light for sterilization onto the filter.
A portable air purifier, comprising:
- a first case including an accommodation space, an inlet through which air is suctioned into the accommodation space on a lateral surface of a lower portion thereof, and an outlet through which air is discharged on an upper side thereof;
- a second case connected to the lower portion of the first case;
- a filter installed inside of the first case and configured to purify air suctioned into the inlet;
- a fan module disposed between the filter and the outlet and configured to rotate a fan to blow air toward the outlet;
- an irradiator disposed at a lower side of the filter and configured to irradiate light for sterilization onto the filter;
- and
- a sterilizer support configured to support the irradiator, fixed to at least one of the first case or the second case and disposed around an outer perimeter of the irradiator, wherein the irradiator comprises:
- a printed circuit board supported by the sterilizer support and disposed at the lower side of the filter;
- and
- a sterilizing light source disposed on the printed circuit board and configured to irradiate light for sterilization onto the filter.
