Suction component and milk bottle applying same

Abstract

The invention discloses a suction component and a milk bottle applying the same. The milk bottle comprises a bottle body, a pressing plate, a suction pipe and a nipple, wherein the bottle body is provided with a top and a bottle bottom; the pressing plate comprises a plate bottom and a circular wall and a peripheral wall both of which are arranged on the plate bottom; the nipple comprises a suction head, a covering part and a bottom edge formed at the periphery of the covering body; the pressing plate is arranged on the top of the bottle body; the nipple is matched with the pressing plate; the suction head, covering part and circular wall are matched to form a first channel; a through hole is opened on the plate bottom surrounded by the circular wall; the suction pipe is sleeved and fixed on the inner wall of the through hole and communicated with the first channel; the bottom edge, circular wall, peripheral wall and the plate bottom between the circular wall and peripheral wall are matched to form a second channel; and an air permeation hole is opened at the plate bottom between the circular wall and peripheral wall, and an air valve is arranged correspondingly to the air permeation hole, thus the second channel is communicated with the inside of the bottle body. The milk bottle has the advantages that automatic air return can be carried out in the milk suction process and the milk cleanness can be guaranteed.

Description

technical field [0001] The invention relates to a feeding bottle, in particular to a feeding bottle which is convenient for sucking and keeping milk clean and a sucking component which is convenient for returning air. Background technique [0002] A feeding bottle for babies generally includes a nipple, a screw cap and a bottle body, and the nipple is positioned on the bottle body through the screw cap. There is a problem in this kind of feeding bottle for a long time, in the sucking process of the baby, along with the reduction of the milk in the feeding bottle, the air pressure in the feeding bottle is reduced to form a certain degree of vacuum, which makes it difficult to suck the milk. see figure 1 A feeding bottle capable of automatically returning air during sucking includes a bottle body 1 , a pressure plate 2 , a straw 3 and a nipple 4 . The pressure plate 2 is provided with a through hole 21, and the through hole 21 is provided with a growing air passage, which di...

AI Technical Summary

Problems solved by technology

This kind of feeding bottle has a problem for a long time. When the baby is sucking, as the milk in the feeding bottle decreases, the air pressure in the feeding bottle decreases to form a certain vacuum, making it difficult to suck the milk.
