Description

PORTABLE AIR CLEANER [0002]

The present invention relates to a portable air purifier.

In general, an air purifier refers to a device that purifies the air quality through a purifying process by sucking the outside air into the air purifier. Such an air purifier can be applied variously according to the intended use and its size, and is generally applicable to a small air purifier that can be used in an indoor space and a large air purifier which can be used in a factory or a wide space.

In this embodiment, the pump 400 operates to allow the outside air to flow into the first case 100. The pump 400 may be operated by a user operating the pump operation button 101 installed on the outer surface of the first case 100. The pressure sensor 270 installed inside the second compartment 220 senses the pressure inside the second compartment 220 to generate pressure information on the PCB 1 and a pressure equal to or higher than a pressure value determined at the PCB 1 When receiving the information, the pump 400 can be operated by sending an operation signal to the pump 400 when the pressure information below the predetermined pressure value is received without sending an operation signal to the pump 400. [

The pump 400 may be operated and the outside air may be sucked into the air inlet 150 and may be introduced into the first compartment 120 through the first filter 310. [ The introduced external air in the state where the dust or foreign matter is filtered by the first filter 310 can be discharged to the intermediate compartment 230 by the pump 400. In the intermediate compartment 230, the second filter 320, which is a composite filter, can be seated in the filter fixing part 130 and the outside air filtered according to the function of the seated second filter 320 is introduced into the first pressure regulating valve 280 may be opened into the second compartment 220 when they are opened.

The PCB 1 may also be electrically connected to the pump 400. The pump 400 may operate inside the first compartment 120 to suck the outside air and discharge it to the intermediate compartment 230. Here, the pump 400 may discharge the outside air sucked through the supply part 410 formed in the pump 400. The supply part 410 may include a first communication hole 140 formed in the filter fixing part 130, And the airtightness can be maintained by the contact through the coupling of the first communication hole 140 and the supply portion 410. [

The first pressure control valve 280 positioned on the second compartment 220 side may be formed in a staggered state without being positioned coaxially with the first communication hole 140. For example, the first communication hole 140 is adjacent to one side of the inner surface of the first case 100, and the second communication hole 240 is adjacent to the other side of the inner side surface of the second case 200 . The communication holes 140 and 240 are provided adjacent to the different inner surfaces of the first case 100 and the second case 200 so that they can be radially distanced from the axis of the case.

At this time, the second filter 320 may be separated from the supply unit 401 and the first pressure control valve 280 to form a tilt. In this structure, since the air discharged from the supply unit 401 for supplying air can use the entire area of the second filter 320 without contacting only a part of the area of the second filter 320, Can be increased. In this structure, the second filter 320 may be formed along the inner circumferential surface of the intermediate compartment 230 and may have a slope adjacent to the inner circumferential surface of the formed filter.
