The case 500 including the second tube 220 and the pump 520 will be described in detail with reference to FIGS. 9 and 10. FIG.

As shown in FIGS. 2 and 3, the support 300 and the pump 520 are connected to each other through the second tube 220. The second tube 220 is coupled to the second tube coupling portion 344 of the second housing 340.

The second tube 220 includes a second tube a 221 connecting the second tube coupling portion 344 of the second housing 340 to the coupling member 540 of the case 500, And a second tube b 223 and a second tube c 224 connecting the suction port 522 of the pump 520 with each other. A third tube 230 is vertically connected between the second tube b 223 and the second tube c 224. The third tube 230 has one end connected between the second tube b 223 and the second tube c 224 and the other end connected to the outlet 534 of the solenoid valve 530.

The second tube a 221 is located outside the case 500 and the second tube b 223, the second tube c 224 and the third tube 230 are located inside the case 500.

The length of the first tube 210 is longer than that of the second tube 220. That is, the support portion 300 is disposed closer to the pump 520 than the feeding cup body 100. Thus, the opening and closing reaction speed of the valve 410 is improved, and the vacuum forming in the feeding cup 110 is easy.

A drive motor 510, a pump 520, and a solenoid valve 530 are installed in the case 500.

The pump 520 has a suction port 522 formed at one side thereof and an outlet port 524 formed at the other side thereof.

The second tube c 224 is connected to the suction port 522 of the pump 520. The second tube 220 and the inner passage 240 of the first tube 210 are evacuated by the drive motor 510 and the feeding cup 110 of the feeding cup body 100 is also in a vacuum state do.

The third tube 230 is connected between the second tube c 224 and the second tube b 223 and is communicated to both sides.

The portion to which the second tube b 223, the second tube c 224 and the third tube 230 are connected forms a T shape.

The vacuum of the tube 200 is released by the operation of the solenoid valve 530 connected to the third tube 230.

At one side of the solenoid valve 530, an inlet 532 and an outlet 534 perpendicular to each other are provided. Suction port 532 is where air enters when solenoid valve 530 is opened. The other end of the third tube 230 is connected to the discharge port 534 and the air introduced through the suction port 532 is discharged to the third tube 230. The air discharged from the discharge port 534 is transferred to the second tube 220 and the first tube 210 through the third tube 230 and the valve 410 opens the flow path 418. Then, the inside of the feeding cup 110 which has been in a vacuum state is changed to an atmospheric pressure state.

The driving motor 510 turns the feeding cup 110 into a vacuum state and then milking the milk and the solenoid valve 530 is opened to feed the outer space 250 into the feeding cup 110 through the flow path 418 Into the inside of the feeding cup 110 at atmospheric pressure. The solenoid valve 530 can quickly change between the vacuum pressure state and the atmospheric pressure state, thereby increasing the efficiency of the milking machine.

As described above, in the breastpump configured as described above, since the valve 410 for opening and closing the flow path 418 and the flow path 418 is formed in the support part 300, the distance to the pump 520 is short, And it is easy to form a vacuum inside the feeding cup 110.

In addition, when the valve 410 is installed in the main body 100, the valve 410 may be lost due to the nature of the main body 100, which requires disinfection, ultraviolet disinfection and frequent cleaning. (300), thereby reducing the possibility of such loss.

In addition, the valve 410 can be easily installed by forming the through-hole 414 in the support portion 300 and sealing the end of the through-hole 414 without preparing a separate injection product.

10, the support portion 300 'in which the flow path 418 is formed and the valve 410 and the cover 420 are installed can be formed as a separate injection molding. In the case of the second embodiment, it is preferable that the support portion 300 'is disposed between the backflow preventing portion including the membrane and the feeding cup body 100.

Hereinafter, the operation of the breastpump having the above-described configuration will be described.

Bring the feeding cup 110 to the user's breast.

The power is turned on to drive the drive motor 510. [

Vacuum pressure is formed in the feeding cup body 100 by the driving force of the driving motor 510 and milk is milked and stored in the storage container 170.

When the solenoid valve 530 is turned on, air flows into the tube 200 through the outlet 534 of the solenoid valve 530, and the valve 410 opens the flow path 418. Then, the air in the outer space 250 flows through the flow path 418 and the inside of the feeding cup 110 is changed to the atmospheric pressure state, whereby the milking is stopped.

When the solenoid valve 530 is turned off, the valve 410 closes the flow path 418, and vacuum pressure is again generated inside the feeding cup 110 to milk the breast milk.
