In addition, the fire extinguishing bomb is integrated into the charger to serve as an internal protection device of the charger, and the charger can be rapidly started when abnormal temperature or other dangerous signals are detected. According to the invention, an efficient and intelligent solution is provided for fire safety in the fields of electronic equipment, energy storage devices and the like.

Description

Technical Field

[0001] The present invention belongs to the field of automatic fire extinguishing technology, and specifically relates to an active fire extinguishing bomb and a charger. The device can automatically release fire extinguishing agent by thermal expansion when a fire occurs, and is particularly suitable for scenes requiring efficient, accurate and intelligent fire extinguishing. Background Art

[0002] With the development of society, fire accidents occur frequently, especially when electronic equipment catches fire, especially mobile phone chargers and charging heads. Traditional passive fire extinguishing devices (such as sprinkler systems) have problems such as slow response speed, complex installation and high maintenance cost. Therefore, there is an urgent need for an intelligent fire extinguishing device that can actively sense the fire source and quickly release the fire extinguishing agent.

[0003] Although there are some active fire extinguishing devices on the market, most of them are limited to fixed devices or devices that require external power control, and cannot meet the needs of portability and intelligence. In addition, the existing fire extinguishing devices are usually lacking in efficient container structure and reliable fire extinguishing agent release mechanism in design.

[0004] In view of the above problems, the present invention proposes an active fire extinguishing bomb based on the principle of thermal expansion and its application scheme, which can quickly respond and release fire extinguishing agent without external intervention when a fire occurs. It automatically triggers rupture and releases liquid fire extinguishing agent by thermal expansion, and can be applied to various equipment that requires fire extinguishing protection (such as chargers). The device has the advantages of simple structure, large fire extinguishing agent capacity, fast response speed, easy installation and maintenance, etc. Summary of the invention

[0005] In order to overcome the above problems, the present invention provides an active fire extinguishing bomb, comprising a container; liquid fire extinguishing agent is sealed inside the container, and the liquid fire extinguishing agent expands when heated to rupture the container for release.

[0006] An active fire extinguishing bomb, wherein the container is made of glass.

[0007] An active fire extinguishing bomb, wherein the container is made of acrylic.

[0008] An active fire extinguishing bomb, wherein the liquid fire extinguishing agent is perfluorohexanone.

[0009] An active fire extinguishing bomb, wherein the container is a tubular structure with both ends sealed.

[0010] A charger is also provided, including a charger body, inside which is configured at least one active fire extinguishing bomb as described above.

[0011] The beneficial effects of the present invention are: the fire extinguishing bomb realizes automatic triggering and efficient response through the principle of thermal expansion, and the shock wave generated by the expansion and cracking is conducive to extinguishing the fire source at one time, without the need for an external power supply or control device. The glass or acrylic container is used, which is compact in design and easy to manufacture with a simple structure and a large amount of fire extinguishing agent; the tubular structure sealed at both ends optimizes the release path and efficiency of the fire extinguishing agent. Perfluorohexanone fire extinguishing agent is non-toxic, environmentally friendly, harmless to the human body and the environment, and environmentally safe. It is not only suitable for chargers, but also can be applied to other equipment that requires rapid fire extinguishing, such as power banks, battery packs and other products. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the three-dimensional structure of the active fire extinguishing bomb of the present invention. DETAILED DESCRIPTION

[0013] This embodiment provides an active fire extinguishing bomb, including a container; a liquid fire extinguishing agent is sealed inside the container, and the liquid fire extinguishing agent is released by the container being ruptured by thermal expansion. The material of the container is glass or acrylic. The liquid fire extinguishing agent is perfluorohexanone. The container is a tubular structure sealed at both ends.

[0014] A charger is also provided, including a charger body, inside which is configured at least one active fire extinguishing bomb as described above.

[0015] Manufacturing of active fire extinguishing bombs: refer to the attached Figure 1 The container is made of high-strength glass or acrylic material and is formed into a tubular structure with a single end seal through a molding process. The wall thickness of the container must meet the requirements of high temperature resistance and pressure resistance to ensure that it can be reliably broken when heated and expanded.

[0016] The fire extinguishing agent is perfluorohexanone liquid, which is non-toxic, environmentally friendly and highly efficient. A certain amount of fire extinguishing agent is filled into the container by vacuum method, and the container is sealed by sealing process. The appropriate bursting temperature is adjusted by adjusting the ratio of air and fire extinguishing agent in the container to ensure that the device is triggered under expected conditions.

[0017] The containers filled with fire extinguishing agent are finally assembled to check their sealing and structural integrity. The reliability of the container is verified through high temperature test and pressure test to ensure that it can work properly under normal use conditions. The fire extinguishing bombs are randomly inspected for temperature test to ensure that they can burst normally and release the fire extinguishing agent within the specified temperature range. Application of active fire extinguishing bombs:

[0018] 1 Application to chargers: Reserve appropriate space inside the charger to install at least one active fire extinguisher. The fire extinguisher can be fixed on the plastic shell of the charger to ensure that it can be quickly triggered and release the fire extinguisher when the charger is overheated or the shell is burning.

[0019] 2 Other application scenarios: The active fire extinguishing bomb of the present invention can also be applied to other electronic equipment, energy storage devices and other fields, such as battery packs, distribution boxes, etc. Through flexible design and configuration, it can meet the fire safety needs in different scenarios.

[0020] The present invention provides an active fire extinguishing bomb based on the principle of thermal expansion and its application in a charger. The device has the advantages of simple structure, fast response speed, environmental protection and safety, etc. It can quickly release fire extinguishing agent when a fire occurs and effectively control the spread of fire. In addition, the present invention has a wide range of applications, not only for chargers, but also for other equipment and places that require efficient fire extinguishing protection.

[0021] Except for the technical features described in the specification, all other technical features are known to those skilled in the art. All equivalent replacements and extensions within the spirit of the present invention should fall within the protection scope of the present invention.
