1 shows an exploded view of an air injection apparatus according to an embodiment of the present invention.

1, the air injecting apparatus 100 includes a first housing part 110, a second housing part 120, an operating part 130, an air passage part 140, a sealing part 150, 160 < / RTI >

The first housing part 110 and the second housing part 120 may form a housing of the air injection device 100. Each of the housing parts 110 and 120 is open at both ends to form an air passage from one end to the other end. The first housing part 110 and the second housing part 120 are detachably coupled to each other in the longitudinal direction so that the air passages of the first housing part 110 and the second housing part 120 can communicate with each other .

A protrusion formed from one end of the second housing toward the first housing part 110 is inserted into the first housing part 110 for coupling the first housing part 110 and the second housing part 120, The first housing part 110 and the second housing part 120 may be coupled to each other. At this time, the protruding portion has an outer diameter corresponding to the inner diameter of the first housing portion 110, thereby enhancing the sealing in the engagement region of the first housing portion 110 and the second housing portion 120.

The operation unit 130 is for receiving a user's selection for opening or closing the air passage in the air injection apparatus 100. At least a portion of the operation unit 130 can be inserted into the first housing 110 and move within the first housing unit 110 And the air passage part 140 moves along with the movement of the operation part 130, so that the air passage can be opened or closed. The uninserted area of the operation unit 130 can receive an operation from the user outside the first housing unit 110. [

Both ends may be formed so as to prevent air communication in the first housing part 110 due to the insertion of the partial area of the operation part 130 and the part of the area may be formed so as to correspond to the inner diameter of the first housing part 110 By having an outer diameter, sealing performance can be enhanced. In order to facilitate the movement of the operation unit 130 in the first housing unit 110, the operation unit 130 may be formed with at least one protrusion projecting in the radial direction, and the first housing unit 110, At least one groove may be formed in the longitudinal direction. By inserting the projection into the groove, it is possible to limit the range of movement of the operation portion 130 within the groove forming range.

The grooves of the first housing part 110 are formed in the longitudinal direction and extend from at least one area (in particular, the end side) of the groove and extend in the circumferential direction of the inner surface of the first housing part 110 A fixing groove may be formed. The projection of the operation unit 130 moves to the fixing groove to prevent the operation unit 130 from moving in the longitudinal direction of the first housing unit 110 so as to maintain the air sealing or opening state of the air injection apparatus 100 .

The air passage section 140 provides a passage for air flow of the air injecting apparatus 100 and is at least partially accommodated in the first housing section 110 and the second housing section 120, And can move in accordance with the movement of the operation unit 130 while the other end can make contact with the hermetic unit 150. Particularly, considering that the front surface of the other end is in contact with the sealing portion 150, the air passage is formed at the side surface of the other end so that the other end of the air passage portion 140 continuously contacts the sealing portion 150 So that the opening or sealing of the air passage can be selectively performed.

The hermetically sealed part 150 is for opening or closing the air passage of the air injection device 100 and is housed in the second housing part 120. The hermetic part 150 is in contact with the other end of the air passage part 140 at one end, So that the ends can contact the elastic portion 160. That is, since the external force in the direction of the first housing part 110 is continuously applied from the second housing part 120 by the elastic part 160, the sealing part 150 is connected to the other end of the air passage part 140 The air passage portion 140 can be moved in the direction of the first housing portion 110 while being in constant contact. Conversely, when the air passage part 140 is moved in the direction of the second housing part 120 by the operation part 130, the sealing part 150 also moves in the direction of the second housing part 120. At this time, the hermetically sealed portion 150 may have a size larger than the inner diameter of one region of the second housing portion 120, so that the hermetically sealed portion 150 opens the air passage of the second housing portion 120 Or may be sealed.

The elastic portion 160 is for applying an elastic force to the sealing portion 150. The elastic portion 160 is received in the second housing portion 120 and has one end contacting the sealing portion 150 and the other end contacting the second housing portion 120). The elastic portion 160 may be formed of a spring, but is not limited thereto, and may be implemented using various elastic bodies according to an embodiment to which the present invention is applied.

The air injection apparatus 100 shown in FIG. 1 is illustrative, and various configurations can be applied according to an embodiment to which the present invention is applied. For example, although the second housing part 120 is shown as two parts, it may be composed of one or more parts according to the embodiment, or the first housing part 110 and the second housing part 120 And the position of at least one of the operation portion 130, the air passage portion 140, the sealing portion 150, and the elastic portion 160 may be changed.

FIGS. 2 and 3 show operation states of an air injection apparatus according to an embodiment of the present invention.

2, a state in which the air passage of the air injecting apparatus 100 is sealed is shown. When the external force is not applied to the manipulation part 130 or the manipulation part 130 moves in the direction of the second housing and is not fixed in position, the resilient part 160 elastically transmits the closing part 150 to the first housing part 110 ) Direction. According to this movement, the sealing portion 150 can seal the air passage of the second housing portion 120.

3, when an external force is applied to the operation unit 130 or the position is fixed to the operation unit 130 in the direction of the second housing unit 120, when the operation unit 130 moves, The first housing part 140 and the second housing part 150 can move in the direction of the second housing part 120 as well. Accordingly, the hermetically sealed portion 150 that hermetically closes the air passage of the second housing portion 120 can open the air passage.

4A and 4B illustrate a functional garment according to an embodiment of the present invention.

Specifically, FIG. 4A shows the functional garment 400 with air being discharged into the air tube 200, and FIG. 4B shows the functional garment 400 with air in the air tube 200 .

As shown, the functional garment 400 may include an air injection device 100, an air tube 200, and garments 300. The air tube 200 may be removably disposed within / outside the garment 300. The air tube 200 is detachably connected to the air tube 200 so that the air can be introduced into or discharged from the air tube 200 while the air tube 200 is in communication with the air tube 200 Lt; / RTI >

The second housing part 120 of the air injection device 100 can be connected to the air tube 200 and the air passage of the air injection device 100 can be opened or closed according to the operation of the operation part 130. [ Air can be introduced into the air tube 200 through the air passage from the operation unit 130 side to the air tube 200 or vice versa. Alternatively, when sealed, the air in the air tube 200 may be maintained in the inflow or outflow state.

Also, as shown, the air tube 200 may be formed in an area corresponding to the neck of the garment 300, but this is exemplary, and the air tube 200 may be a joint part of the body such as the wrist, It can be formed in various regions necessary for impact absorption from outside or posture support.
