Problems solved by technology

[0002] In the field of mother and baby products, straws are a commonly used item; because when using a straw to absorb liquid, the liquid quickly flows into the mouth from the port of the straw, and when the temperature of the liquid is high, if you do not pay attention, it is very likely to burn the baby's mouth ; Therefore, when the accompanying energy is limited, it is more dangerous to make the baby use a common straw to suck heated liquid, such as milk

Embodiment 2

[0017] exist figure 2 In the shown embodiment 2, the mother and baby anti-scald straw includes a metal closed cavity 1 at the lowest end, and the closed cavity 1 is provided with a strong magnetic slider 11 that can slide up and down along the axis of the straw; Kerosene 12 is sealed in the airtight area below the plug 11, and air 13 is enclosed in the airtight area above the strong magnetic sliding plug 11; a transition chamber 2 is provided above the closed chamber 1, and an inlet is provided on the side wall of the transition chamber 2. A water hole 21, the upper end of the transition chamber 2 is provided with a water outlet hole 22; the top of the transition chamber 2 is connected to the main body of the suction pipe 4; When the magnetic sliding plug 23 slides to the bottom of the transition chamber 2, the side wall of the ferromagnetic sliding plug 23 blocks the water inlet hole 21 of the transition chamber, and when the ferromagnetic sliding plug 23 slides to the top o...

Abstract

The invention provides an anti-scald straw for a baby. The anti-scald straw for the baby comprises a metal closed cavity, and a strong magnetic sliding plug which can slip and move up and down is arranged in the metal closed cavity; kerosene and air are closed in enclosed areas below and above the strong magnetic sliding plug respectively; a transition cavity is above the closed cavity, and an inlet opening and an outlet opening are formed in the side wall and the upper end of the transition cavity; a switch cavity is above the transition cavity, the upper part of the switch cavity is connected to a straw body, and a through-water plate which confines a ferromagnet in the switch cavity is arranged between the switch cavity and the straw body; when the ferromagnet falls into the bottom of the switch cavity, the ferromagnet blocks the outlet opening above the transition cavity; when the temperature of the kerosene is less than 40 DEG C, the strong magnetic sliding plug descends, at this time, the largest suction of the strong magnetic sliding plug on the ferromagnet is less than the product of the standard atmospheric pressure and the area of the outlet opening; when the temperature of the kerosene is larger than 45 DEG C, the strong magnetic sliding plug rises, at this time, the smallest suction of the strong magnetic sliding plug on the ferromagnet is larger than the product of the standard atmospheric pressure and the area of the outlet opening. The anti-scald straw for the baby can be automatically closed when the temperature of the liquid is high so as to prevent an oral cavity from being scalded.

Description

technical field [0001] The present invention relates to the field of maternity and infant products, in particular to a straw. Background technique [0002] In the field of mother and baby products, straws are a commonly used item; because when using a straw to absorb liquid, the liquid quickly flows into the mouth from the port of the straw, and when the temperature of the liquid is high, if you do not pay attention, it is very likely to burn the baby's mouth Therefore, when the accompanying energy is limited, it is more dangerous to make the baby adopt a common straw to suck the heated liquid, such as milk. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an anti-scald straw for mothers and babies, which can be automatically closed when the temperature of the liquid is high, so as to prevent oral burns. [0004] The first technical solution adopted by the present invention to solve the technical problem i...
