Anti-scald straw and straw cup

Abstract

The invention discloses an anti-scald straw and a straw cup. The anti-scald straw comprises a straw body and a shell body, the shell body is provided with an upper opening and a lower opening, the upper opening is connected with the lower end of the straw body, and a thermostatic valve element is fixed to the middle of the shell body; a sealing cap sleeves the end of a piston of the thermostatic valve element, a boss is arranged at the bottom of the sealing cap, and a spring sleeves the sealing cap between the boss and the lower end of the upper opening; the straw cup comprises a cup cap and acup body, and the upper end of the straw body is connected with a water inlet of the lower end of a suction nozzle of the cup cap. When the temperature of the lower end of the thermostatic valve element is higher than or equal to a preset temperature, the piston drives the sealing cap to move upward so as to seal a lower end port of the upper opening. According to the anti-scald straw and the straw cup, the oral cavity can be prevented from being scalded by water, use safety is ensured, the cost is low, and the straw and the straw cup are free of toxicity, stable and durable.

Description

technical field [0001] The invention relates to a straw, in particular to an anti-scald straw for a water container and a straw cup using the anti-scald straw. Background technique [0002] A water container, such as a straw cup, is a water cup commonly used in our daily life, and the straw at the mouth of the cup is especially suitable for sucking by infants and the elderly. However, when high-temperature liquids (such as boiling water and milk) are contained in the sippy cups, they need to be cooled before they can be drunk. If there is a slight negligence, sucking hotter liquids will burn the mouth. [0003] In order to prevent scalding, someone installs a shape memory alloy clip or a bimetallic sheet on the lower end of the straw (Application No. water bottle"), if the temperature of the liquid in the cup is higher than the safe temperature, the shape memory alloy clip or bimetal will clamp or block the lower end of the straw to prevent hot water from entering the straw...

Problems solved by technology

However, these structures have the following disadvantages: using shape memory alloys, in order to generate sufficient blocking force, the amount of shape memory alloys is large, the manufacturing cost is high, and there is a risk of fracture after long-term frequent repeated deformation; To produce sufficient blocking force, the dosage is large, the cost is high, and after long-term frequent and repeated deformation, the effect of closing the straw will gradually decrease
