突然炸了！杭州女子吓懵：热水喷射，被烫到水泡密密麻麻！不少人家里也有

Core Viewpoint - The article highlights the dangers associated with using low-quality thermos cups, which can lead to serious injuries, as illustrated by a recent incident where a woman suffered burns due to a thermos cup explosion [1][2]. Group 1: Incident Overview - A woman in Hangzhou received a thermos cup as a promotional gift after purchasing certain products, which later exploded when she attempted to sanitize it with boiling water, resulting in second-degree burns on her feet [1][2]. - The incident is not isolated, as similar cases have been reported, indicating a pattern of accidents involving thermos cups under specific conditions [3][5]. Group 2: Causes of Explosion - The primary reasons for thermos cup explosions include: 1. Microbial fermentation, where bacteria in the cup can produce gas when food items like red dates or goji berries are soaked, increasing internal pressure [6]. 2. Chemical reactions, particularly when cleaning agents react with residues in the cup, generating gas that can lead to pressure buildup [7]. 3. Forceful shaking of the cup after adding hot water and effervescent tablets, which can significantly increase internal pressure [8]. Group 3: Safety Recommendations - Consumers are advised to choose thermos cups from reputable brands with quality certifications to avoid low-quality products that may lack proper sealing and pressure resistance [5]. - It is recommended to avoid filling thermos cups with boiling water, shaking them, or storing easily fermentable foods for extended periods [14]. - When cleaning thermos cups with descaling agents, users should not seal the lid tightly or shake the cup to prevent pressure buildup [14].
