An air purifier includes a case having an air inlet and an air outlet, a fan disposed adjacent the air inlet, a UV LED unit and a filter unit arranged over the fan along a flow path of air, and a fluid control structure disposed between the fan and the filter unit.

Air purifier using ultraviolet rays

A sterilizer is provided to include: a first pipe having an inner wall with a light reflecting property; a second pipe disposed in the first pipe so as to pass fluid therethrough and formed of a light transmitting material; and a plurality of UV LEDs arranged on the inner wall of the first pipe and configured to irradiate sterilization UV light onto the fluid.

Fluid sterilizer and associated connecting device

A sterilizer may include: a first pipe having an inner wall with a light reflecting property; a second pipe disposed in the first pipe so as to pass fluid therethrough and formed of a light transmitting material; and a plurality of UV LEDs arranged on the inner wall of the first pipe and configured to irradiate sterilization UV light onto the fluid.

The present invention relates to an air cleaner and, more particularly, to an air cleaner provided with a housing divided into an outer housing and an inner housing, wherein the outer housing and the inner housing are separated from one another, a photocatalytic filter and a collection filter are installed in the inner housing, and air flows even through the space between the inner housing and the outer housing. The present invention provides an air cleaner comprising: an outer housing defining an inlet and an outlet; an inner housing disposed in the outer housing and formed to be separated from the outer housing; a fan installed in the inner housing to forcibly discharge air in the outlet direction; a photocatalytic filter installed in the inner housing and disposed in the direction in which air from the fan is discharged or in the direction opposite to that in which the air is discharged; and an ultraviolet light source disposed upstream of the photocatalytic filter in the direction of airflow created by the fan in order to irradiate the photocatalytic filter with ultraviolet rays.

Air cleaner

An air cleaner is provided to include a photocatalytic UV LED () installed on an UV LED substrate (), and a photocatalytic filter installed on a surface facing the photocatalytic UV LED while being spaced apart from the UV LED substrate. The photocatalytic filter has a structure in which a photocatalytic material is coated on a base in which a plurality of cells () defining an air flow path in a direction toward the photocatalytic UV LED are arranged in parallel adjacent to each other.

Compact air cleaner using UV LED and photocatalytic filter

A mobile phone charger with a sterilization UV LED may include: a charger case having a space formed therein and including a mobile phone stand formed at the front surface thereof; and one or more first UV LEDs installed at one side of the space of the charger case.
