Abstract

The utility model provides a one-way flow guide device of a feeding bottle straw, which can effectively prevent milk liquid from flowing back. The bottom of a flow guide pipe is provided with a one-way valve for preventing the milk liquid from flowing back; the one-way valve comprises a valve cover, a valve body and a valve core; the upper part of the valve cover is provided with a connecting pipe which is sleeved with the flow guide pipe; the valve cover is connected with the valve body in a sleeved manner or in a threaded manner; the valve core is a wafer of which the side surface is provided with a rotating shaft; the valve body is provided with a shaft seat and a ring-shaped platform, which are respectively and mutually corresponding to the rotating shaft and the wafer of the valve core; and when milk water goes up, the valve core is opened, and when milk water inhalation is stopped, the valve core is closed along with the milk water. The one-way flow guide device can thoroughly solve the milk water backflow problem, and enable that the milk liquid in the flow guide pipe cannot flow back to the bottom of the bottle body.

Description

The unidirectional guiding device of feeding bottle suction pipe

Technical field

This utility model relates to the infant feeding bottle manufacturing technology, specifically is meant the unidirectional guiding device of feeding bottle that prevents that milk from refluxing in mozzle.

Background technology

In the prior art, a kind of feeding bottle of establishing mozzle in bottle is arranged, mozzle extends to bottle body bottom from the bottle oral area always, establishes the spheroid of through hole in the bottom of mozzle connection one.Adopt this set, when placing down at the bottom of the feeding bottle bottle, infant can be sucked the milk in the bottle equally.Along with the minimizing of milk in the bottle, a negative pressure increases in the bottle, makes baby's difficulty that sucks, and baby's nipple of having to open one's mouth to unclamp is sucked air and had the hiccups easily like this.Prior art is established into return-air hole on nipple, or the nipple top is made as the anti-backflow of cross mouth, but this technical scheme has weak point, as the distortion of feeding bottle gas channel or when stopping up, micro-strain etc. can take place in nipple when infant was sucked, and caused infant to suck difficulty; In addition, when sucking at interval, the milk in the mozzle will cause at every turn and suck at the bottom of be back under the effect of gravity bottle, all can form one section cavity in mozzle.Therefore, this technical scheme can not solve infant at all and sucks the problem that air is had the hiccups.

Summary of the invention

The technical problems to be solved in the utility model is that a kind of unidirectional guiding device of feeding bottle suction pipe that can prevent effectively that milk from refluxing is provided.

The technical solution of the utility model is such, and the unidirectional guiding device of feeding bottle suction pipe comprises mozzle, it is characterized in that: be provided with one in the bottom of mozzle 1 and prevent the check valve 2 that milk refluxes.

Described check valve 2 is made up of valve gap 3, valve body 4 and spool 5, connection tube 6 and mozzle 1 socket are established in valve gap 3 tops, valve gap 3 is with valve body 4 sockets or be threaded, spool 5 is established the disk of rotating shaft for the side, valve body 4 is provided with axle bed, ring-shaped platform, and rotating shaft and the disk with spool is corresponding mutually respectively, spool 5 was opened when milk was up, and spool 5 is closed with milk when stopping inhaling.

The beneficial effects of the utility model mainly show: can thoroughly eliminate the problem that milk refluxes, make the milk in the mozzle not be back to bottle body bottom.It is laborsaving, smooth and easy that infant sucks, and do not suck air.Simple in structure, design science is reasonable.

Description of drawings

Fig. 1 is this utility model theory structure sketch map.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described further.

The unidirectional guiding device of feeding bottle suction pipe with reference to Fig. 1, is provided with one in the bottom of mozzle 1 and prevents the check valve 2 that milk refluxes, and check valve 2 adopts plastic production.

Described check valve 2 is made up of valve gap 3, valve body 4 and spool 5, valve gap 3 is with valve body 4 sockets or be threaded, its joint face closely contacts, connection tube 6 and mozzle 1 socket are established in valve gap 3 tops, and spool 5 is established the disk of rotating shaft for the side, and valve body 4 is provided with axle bed, ring-shaped platform, the rotating shaft of spool 5 is arranged on the axle bed of valve body 4 correspondences, the disk of spool 5 is corresponding mutually with the ring-shaped platform of valve body 4, and spool 5 was opened when milk was up, and spool 5 is closed with milk when stopping inhaling.

Before sucking, the ring-shaped platform on the disk of spool 5 and the valve body 4 coincide, and check valve 2 is closed; When upwards sucking, the disk of spool 5 upwards rotates around the shaft, and check valve 2 is opened, and milk upwards enters mozzle 1 by check valve 2; When stopping to suck, spool 5 is with the milk return, and the ring-shaped platform of the disk of spool 5 and valve body 4 coincide, and stops up flow-guiding channel, make milk can not Backflow bottle at the bottom of.
