Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to an active rapid fire extinguishing device for charging electronic devices. Background Technology

[0002] With the widespread use of charging electronic devices such as smartphones, tablets, power banks, small charging devices, two-wheeled vehicles, and three-wheeled vehicles, their built-in lithium-ion or sodium-ion batteries are highly susceptible to thermal runaway under conditions such as overcharging, short circuits, and physical damage. This causes the device's temperature to rise rapidly in a short period of time, potentially accompanied by gas leaks, smoke, fire, or even explosion. Such fires are characterized by their suddenness, high flame temperature, and the potential production of toxic gases and jet flames, posing a serious threat to the personal safety and property of users.

[0003] Currently, the public generally lacks effective and safe means of handling such fires. While commonly used ABC dry powder fire extinguishers can extinguish fires, their effectiveness against lithium battery fires is limited, and the powerful impact and dust can cause secondary damage to delicate charging electronic devices. Furthermore, their use in confined spaces such as indoors is inconvenient. Fire blankets can extinguish fires by covering them, but they cannot effectively suppress the ongoing reactions inside lithium batteries, making reignition easy. Moreover, covering the fire requires the user to be close to the fire source, posing a safety risk. Therefore, there is a need for an active, rapid fire extinguishing device for charging electronic devices, designed to address the aforementioned problems. Utility Model Content

[0022] The temperature-sensing trigger unit 10 is fixed in the flexible fire-resistant bag body 1 and the insulating bag 5 with the inner side embedded with insulating material. It is used to sense the temperature inside the bag and generate a trigger action when the predetermined threshold temperature is reached. The flexible fire-resistant bag body 1 is equipped with a temperature display 3 to facilitate the display of temperature changes inside the bag. The temperature-sensing trigger unit 10 includes an automatic triggering device, a temperature display 3, and an alarm device.
