The connection part 30 is connected to the body part 10 and can position the body part 10 so as to be in close contact with the neck, collarbone or face of the user.

The body 10 may be formed to at least partially bend so as to surround a part of the user's neck, collarbone or face. For example, the body portion 10 may be formed in a horseshoe or " U " shape. That is, the body portion 10 may be formed with both side ends spaced from each other and a part of the extending portion extending from both side ends round. The connection portion 30 is connected to the opposite ends of the body 30 to prevent detachment of the body 10 mounted on the user's neck, collarbone or face.

The connection part 30 is connected to the body part 10 and may contact the neck or back of the user. The connection portion 30 may be formed of a flexible and elastic material by contacting the user's body. That is, the connection portion 30 can be supported at the user's neck or back pass so that the body portion 10 is stably fixed to the user's neck, collarbone or face. For example, the connection 30 may be provided as a "belt", "synthetic fiber", "elastic fiber", "suspenders", or the like. Alternatively, a part of the connection part 30 may be formed of a flexible and elastic material, and the other part of the connection part 30 may be formed of a material that is rigid or can be stably fixed. It is not limited to this idea.

The body portion 10 may include an outer frame 11, an inner frame 12, and a pad portion 14.

The outer frame 11 may form an outer surface of the body 10. The outer frame 11 may refer to a portion exposed to the outside when the air cleaning apparatus 1 is mounted on the user's neck, collarbone or face. The outer frame 11 may have a second virtual surface formed by connecting lower ends of the first virtual surface formed by connecting upper ends thereof. That is, the outer frame 11 may be formed so that a part of the outer frame 11 is inclined. For example, when viewed from the side of the outer frame 11, the outer frame 11 may be formed in a " sun cap " shape in which the size is gradually reduced in the direction from the second virtual surface toward the first virtual surface. The first imaginary plane and the second imaginary plane may be formed in the same manner. However, when the outer frame 11 is formed to be inclined as in the present embodiment, the outer frame 11 may be disposed adjacent to the user's neck, collarbone, or face when the user's neck, collarbone, or face is mounted. In addition, the outer frame 11 can be provided with a beautiful appearance to perform the function of the ornament.

 The outer frame 11 may be provided with a display unit 101 for indicating the operation of the air cleaning apparatus 1. [ The display unit 101 may be located on an outer surface of the outer frame 11. For example, the display unit 101 may be provided as an LED, an illuminating unit, or the like that visually shows the operation state of the device, or may be provided as an acoustic unit for audibly indicating the operation state of the device. In the present embodiment, the display unit 101 is provided as a plurality of LEDs. When the device is operated, the display unit 101 can display an operation state by blinking a plurality of LEDs.
