Description

Suction device structure of breastpump

The present invention relates to the structure of the suction power generating device of the breast pump, and more particularly, to the structure of the suction power generating device of the breast pump which can minimize noise and use the suction power in various stages according to the user's use condition.

In general, breast pumps are used when mothers squeeze colostrum after labor or forcibly squeeze the remaining milk during lactation. There are manual and electric motors that are usually used by hand.

Usually, during the first week after delivery, the mother changes from colostrum to mature milk, which results in breast milk filling, which gradually decreases in 3-5 days.

At this time, if the infant is not properly breastfeeding, the breast becomes hard and develops breast congestion (Breast engorgement) accompanied by burning pain.

As a result, in order to prevent breast congestion of mothers, feeding should be frequently performed about 8-12 times a day, and when breastfeeding is missed, artificially squeezing breast milk should be performed.

Breast pumps are commonly used to artificially squeeze mother's or lactating mother's milk.

Manual breast pumps are not only laborious but also inconvenient to use because pumping operations are performed by the mother by hand pressing. Recently, there have been many automatic breast pumps that can solve the inconvenience of manual breast pumps.

However, conventional automatic breast pumps have several disadvantages.

First, since the strength of the suction force is controlled by the inflow of external air, there is a problem in that the motor must be continuously operated during use, which consumes a lot of current.

Second, since the breast pump body is directly attached to the upper part of the breast milk storage bottle, there is a high risk of failure or internal contamination of the breast pump body due to the inflow of breast milk.

Third, since the breast milk coming into the breast milk storage bottle through the suction port is buried intact on the inner surface of the breast milk bottle cap, there is a disadvantage that it must be disinfected every time.

In addition, the existing automatic breast milking machine that automatically sucks breast milk using a vacuum pump is not able to control the degree of vacuum and sucks breast milk at a constant vacuum, so it is impossible to control the vacuum according to the mother's constitution and breast milk. There is a problem that is damaged.

In addition, since the piston-type vacuum pump is employed, the viscosity of the grease decreases due to frictional heat of the piston and the piston, and there is a problem that the degree of vacuum decreases with use for a long time.

In this case, in order to operate smoothly, the user must apply industrial grease to the piston, but there is a problem in that the operation of disassembling the vacuum pump and applying grease is difficult.

In addition, in the case of mothers with a large amount of breast milk, it is impossible to control the vacuum time, resulting in a decrease in milking efficiency, and excessive suction in the vacuum, causing breast milk to flow back into the machine, thereby causing a breakdown of the machine.

In addition, the conventional breast pump has a problem in that the mother's milk flows back when the mother squeezes the mother in a lying or lying position.

Accordingly, the present invention has been made in view of the problems of the prior art as described above, the suction force generating device structure of the breast pump, which receives the driving force by the belt and the suction force is generated by the piston moving by the spiral coupling, can be used simply and quietly. The purpose is to provide.

In addition, another object of the present invention is to adjust the stroke length of the piston by the operation of the switch in several stages so that the strength of the suction force can be used without objection according to the user's physical condition.

In addition, another object of the present invention is to form a projection ring on the outer peripheral surface of the piston ring to minimize the friction force with the cylinder and to prevent the suction force is lost.

In order to achieve the above object, the present invention is a breast pump consisting of a bottle for storing breast milk in the lower portion of the suction trumpet connected to the suction force generating unit and the hose, the pipe-shaped male spiral rod is formed inside the cylindrical cylinder Suction force is generated by installing a piston and a suction body generating a suction force generating a suction force linearly reciprocating the piston and generating a suction force by rotating the rotating body formed with a female spiral hole which is spirally coupled to the male spiral rod by the driving force of the stationary motor. And a suction nozzle having one or more suction pipes formed at one end of the cylinder to generate suction force, and exposed to one side of the case, thereby supplying suction force to the suction unit that pumps breast milk through a hose connected thereto. It provides a suction force generating device structure of the breast pump constituted by.

As described above, the present invention has the effect that the suction force is generated by the piston moving by the helical coupling and the driving force is transmitted to the belt and can be used simply and quietly.

And, by adjusting the stroke distance of the piston by the operation of the switch in a number of steps through the control of the strength of the suction force can be used without a sense of rejection according to the user's physical conditions.

In addition, by forming a projection ring on the outer peripheral surface of the piston ring has the effect of minimizing the friction force with the cylinder and the suction force is not lost.

At this time, the sealing member 40 is coupled to the extension tube 33 and a pair of sealing membrane 42 formed in a thin thickness to the lower portion of the body 41 for temporarily storing breast milk is in close contact.

That is, when the suction force supplied through the hose 22 acts on the suction unit 30, the sealing membrane 42 is in close contact with each other, and when the suction force disappears, the adhesion is released to configure the mother milk to flow into the feeding bottle 34. .

Hereinafter, the operation and operation of the present invention will be described.

As shown in FIGS. 4 to 7, in order to use the breast pump 100, a piston ring 13b is positioned between the first piston 13d and the second piston 13e and then coupled to the piston 13. To complete).

Then, the piston 13 is inserted into the first cylinder 11e and the second cylinder 11f while being engaged with the female spiral hole 15 of the rotating body 16 by the male screw rod 12. .

Subsequently, in the process of coupling the first cylinder 11e and the second cylinder 11f, the stationary motor 17 is fixed to the holder 11f 'of the second cylinder 11f, and the stationary motor 17 is rotated. The whole 16 is joined while connecting with a belt.
