Technical Field

[0001] The utility model belongs to the technical field of electronic cigarette storage, and in particular relates to a fire extinguishing device used in an electronic cigarette cabinet. Background Art

[0002] With the rapid growth of the e-cigarette market, safety and regulatory issues are becoming increasingly prominent, particularly in the storage process. E-cigarette products contain lithium battery components. If subjected to external forces such as squeezing or puncture during storage, or if the e-cigarettes themselves contain defects, they can easily cause internal short circuits, further triggering serious safety accidents such as spontaneous combustion and explosion, posing a significant threat to storage safety. Furthermore, tobacco monopoly management departments typically store e-cigarettes in explosion-proof cabinets. However, when an e-cigarette in an explosion-proof cabinet catches fire, management personnel are unable to detect and address it promptly, and by the time they are discovered, it is often completely burned out. Furthermore, explosion-proof cabinets only provide passive protection and physical isolation, and cannot prevent the spread of fire within the cabinet. Utility Model Content

[0032] First embodiment:

[0033] like Figure 1-6 As shown, this embodiment provides a fire extinguishing device for an electronic cigarette cabinet, including a box body 1 that can be set in an explosion-proof cabinet 23. A fire extinguishing chamber 2 for accommodating a fire extinguishing component is provided in the box body 1. The fire extinguishing chamber 2 is connected to the ejection component 3. A starting component 4 is also provided in the fire extinguishing chamber 2. When the starting component 4 detects a fire source, the starting component 4 triggers the fire extinguishing component, and the fire extinguishing agent in the fire extinguishing component is ejected outward through the ejection component 3. The fire extinguishing agent is liquid perfluorohexanone.

[0034] When a fire occurs in the explosion-proof cabinet 23 storing electronic cigarettes, the starting component 4 triggers the fire extinguishing component in the fire extinguishing chamber 2, and the liquid perfluorohexanone in the fire extinguishing component is sprayed into the explosion-proof cabinet 23 through the spraying component 3 to extinguish the fire. After the liquid perfluorohexanone is sprayed out by the spraying component 3, it vaporizes quickly, has high cooling efficiency, high fire extinguishing efficiency, is not easy to produce residue, will not damage the electronic cigarettes that have not caught fire in the explosion-proof cabinet 23, and reduce losses. In addition, perfluorohexanone is non-conductive and will not cause secondary damage to lithium batteries, etc., and the device has a small structure and is easy to install.

[0035] The fire extinguishing component includes a fire extinguishing agent package 5 and a gas generating component 10 capable of generating a large amount of booster gas in the fire extinguishing chamber 2 to push the fire extinguishing agent to flow toward the ejecting component 3. The gas generating component 10 is controlled by the starting component 4.

[0036] like Figure 3As shown, the fire extinguishing chamber 2 is separated into a first chamber 6, a second chamber 7 and the three chambers thereof by a first isolation plate 11 and a second isolation plate 12. A fire extinguishing agent bag 5 is provided in the first chamber 6, and the first chamber 6 is provided with a first opening 13 connected to the spraying component 3. A sealing isolation paper 9 is provided at the first opening 13. A gas generating component 10 is provided in the second chamber 7, and a starting component 4 is provided in the third chamber 8.

[0037] The fire extinguishing agent bag 5 contains fire extinguishing agent, which is easily decomposed by high temperature.

[0038] The gas generating component 10 is an aerosol gas generating charge column, and the gas generating component 10 can generate a large amount of aerosol according to the heat transferred after the second isolation plate 12 is triggered from the starting component 4.

[0039] The starting component 4 is connected to an external temperature control device. When triggered, the starting component 4 can generate high temperature, which is transferred to the gas generating component 10 in the second chamber 7 through heat conduction through the second isolation plate 12. The starting component 4 and the external temperature control device are both existing devices and will not be described in detail.

[0040] A plurality of vents 19 are provided on the first isolation plate 11 .

In other embodiments, at least one first chamber 6, one second chamber 7, and one third chamber 8 are provided. The number of each chamber can be adjusted according to actual needs.

[0046] Working principle:

[0047] When a fire occurs in the electronic cigarette in the explosion-proof cabinet 23, the starting component 4 generates high temperature, and the high temperature is transferred to the aerosol gas generating column in the second chamber 7 through the second isolation plate 12. A large amount of aerosol with a certain amount of heat generated by the aerosol gas generating column can enter the first chamber 6 through the vent 19 on the first isolation plate 11. The fire extinguishing agent bag in the first chamber 6 is made of PP material. After being decomposed by heat, the aerosol drives the liquid perfluorohexanone to break through the sealing isolation paper 9 at the first opening 13 and is sprayed out through the spraying component 3.

[0048] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
