The utility model discloses a solve the technical scheme that its technical problem adopted and be: a check valve built in a straw comprises a straw body, a hose and a gravity ball, wherein a through flow channel is arranged on the straw body, an interlayer is arranged at the upper end of the flow channel, a hole structure in a normally closed state is arranged on the interlayer, the upper end of the hose is communicated with the lower end of the flow channel on the straw body, the gravity ball is fixedly installed at the lower end of the hose, and a milk inlet hole communicated with the hose is formed in the gravity ball.
As a further improvement of the utility model, the hole structure of the normally closed state on the interlayer is an incision, and the side wall of the incision is in elastic close contact with the incision.
As a further improvement of the utility model, the notch is a straight notch or a cross notch.
As a further improvement of the utility model, the interlayer is an arc-shaped structure which is convex upwards.
As a further improvement of the utility model, the straw body comprises a hard body and a soft body, the soft body is integrally formed on the hard body and on the side surface, and the interlayer is a part of the soft body.
As a further improvement of the utility model, the upside of the straw body forms an arc-shaped concave surface.
As a further improvement, the straw body upper end forms the diameter and expands the structure outward, and the diameter expands the structure downside outward and is formed with the location lug that matches with the inboard recess of feeding bottle lid.
As a further improvement of the utility model, the straw body is also provided with a connector, the connector sleeve is arranged outside the upper end of the hose, and the connector can fixedly connect the hose with the flow channel on the straw body.
The utility model has the beneficial technical effects that: the utility model discloses a set up the interlayer on this internal runner of straw, set up the incision that is in normally closed state on the interlayer, this incision forms a check valve, realizes the one-way function of advancing the milk of straw, and the incision that forms negative pressure normally closed state between straw body and the nipple when baby inhales milk is opened, and the incision that the negative pressure disappears normally closed state when baby stops inhaling milk is closed, and the milk in the space between nipple and the check valve can not flow backwards the feeding bottle in, makes things convenient for the baby to easily eat milk, the utility model discloses simple structure, the manufacturing of being convenient for, and easy to assemble dismantlement, the cleanness of being convenient for is difficult for breeding the bacterium, is favorable to the baby healthy.

Detailed Description
Example (b): the utility model provides a built-in check valve of straw, includes straw body 1, hose 3 and gravity ball 4, be equipped with a runner that runs through on the straw body 1, this runner upper end is equipped with an interlayer 7, is equipped with a pore structure that is in normally closed state on the interlayer 7, and 3 upper ends of hose and 1 upper flow channel lower extreme intercommunication of straw body, gravity ball 4 fixed mounting are in the 3 lower extremes of hose, are formed with the hole of suckleing that communicates with hose 3 on the gravity ball 4.
When a baby sucks milk, the hole structure which forms a negative pressure normally closed state between the suction tube body 1 and the nipple is opened, when the baby stops sucking milk, the hole structure which forms a negative pressure disappearance normally closed state is closed, milk in the space between the nipple and the one-way valve cannot flow back to the feeding bottle, and the baby can easily eat the milk.
The hole structure of the interlayer 7 in a normally closed state is a notch 8, and the side walls of the notch 8 are in elastic tight contact. When the baby sucks the milk, a negative pressure notch 8 is formed between the suction tube body 1 and the nipple and is opened, when the baby stops sucking, the negative pressure disappears, and the elastic side wall of the notch 8 resets to close the notch 8.
The notches 8 are straight notches 8 or cross notches 8, and can also be flower-shaped notches 8 and the like.
The interlayer 7 is of an arc-shaped structure protruding upwards, (the structure is beneficial to opening the notch 8 in a negative pressure state, and meanwhile, the notch 8 automatically resets after negative pressure disappears.
The suction tube body 1 comprises a hard body 6 and a soft body 5, the soft body 5 is integrally formed on the upper side face of the hard body 6, an interlayer 7 is a part of the soft body 5, the hard body 6 is used for being positioned at the inner side of the nipple, and the soft body 5 is used for forming the interlayer 7 and being tightly and hermetically connected with the nipple.
An arc-shaped concave surface is formed on the upper side of the straw body 1.
The upper end of the straw body 1 forms a diameter outward-expanding structure, and a positioning bump matched with a groove in the inner side of the milk bottle cap is formed on the lower side of the diameter outward-expanding structure. The structure is convenient for the positioning of the suction tube body 1 and the nipple, and the negative pressure is formed between the suction tube body 1 and the nipple when the baby eats the milk.
Still be equipped with connector 2, the connector 2 cover is located the hose 3 upper end outside, and connector 2 can be with hose 3 and the runner fixed connection on the straw body 1. The hose 3 and the flow channel on the suction pipe body 1 can be conveniently communicated and detached, and the cleaning and the replacement are convenient.
