Although these sterilizers use UV light to sterilize, there may be a shaded area where UV light does not reach all areas of the accessory, and there may be disadvantages that bacteria growth or odor generation may occur in the area where UV light does not reach. have.

The present invention provides a portable sterilizer capable of eliminating or minimizing a shaded area and preventing bacterial propagation or odor generation.

According to an exemplary embodiment of the present invention for achieving the above-described objects of the present invention, a portable sterilizer for sterilizing small items such as a mask or a mobile phone corresponds to a case for accommodating the small items, and the shape of the small items in the case It is formed so as to include a net support for supporting the props within the case, a first sterilization lamp mounted on one side of the inner surface of the case with respect to the net support, and a second sterilization lamp mounted on the other side of the inner surface of the case with respect to the net support. .

A sterilization target such as a mask or mobile phone is placed on the net support, and the first sterilization lamp and the second sterilization lamp are irradiated with ultraviolet rays from opposite sides in the case to safely complete sterilization without a shadow area from the top and bottom or left and right.

In addition, the net support enables sufficient access of the sterilization light by internal contact by separating the sterilization target by a predetermined distance from the inner wall of the case, and prevents drying interference by contact after sterilization.

For example, the first germicidal lamp may be mounted on the ceiling of the case, and the second germicidal lamp may be mounted on the floor of the case. In addition, a plurality of first and second germicidal lamps may be mounted, and the scanning directions of the second germicidal lamps may be arranged to be inclined to each other, specifically, to open upwards. ^One

Therefore, during sterilization, outside air can be introduced from the lower part of the case, and the inlet is spaced a certain distance from the floor around the lower part of the case, so that the air can be smoothly introduced.

In addition, the fan for introducing air may use a brushless direct current (BLDC) motor, a general motor, or the like, and may accommodate various aroma modules by forming an aroma accommodating part at the inflow side of the fan. The use of the aroma module may be variously selected such as air cleaning, aroma, and other sterilization, and the aroma module may also be provided using various media and ingredients. As the fan operates, the material of the aroma module accommodated in the aroma receiving unit may be introduced into the case together with air.

The net support may be formed using a transparent or opaque material, and may correspond to the shape of a small object to be sterilized. For example, if the accessory is a mask, the net support may be provided in a convex shape to support the mask three-dimensionally, and if the accessory is a mobile phone, the net support may be provided in a flat shape.

The portable sterilization apparatus of the present invention uses a plurality of sterilization lamps, and by using a net support to arrange the sterilization lamps of the same or different types on both sides, it is possible to minimize the use of a reflector or to provide a uniform sterilization effect without using it at all. .

The net support is also supported three-dimensionally in response to the sterilization props, so that the sterilization lamp is evenly delivered to the outer surface of the props, as well as maintaining an appropriate distance from the sterilization lamp to maintain the sterilization power uniformly and at the same time to prevent the props from being biased. can do.

In addition, the net support prevents small items from moving inside the case or coming into contact with the inner wall of the case, so that the drying process is not disturbed through contact with the inner wall, and odor is not generated.
