[0002] At present, in order to facilitate travel, more and more people choose to ride electric bicycles to go out, and the power batteries of the electric bicycles are mostly lead-acid batteries or lithium batteries, which are installed on the electric bicycles in the form of battery boxes. Although this mode is convenient, the safety is not good enough. When the electric vehicle is charging, if it catches fire, or when the battery short-circuits due to any reason, the energy in the battery will be released in the form of heat in a short time, which can ignite the internal components of the lithium battery, or cause the battery package to break, the electrolyte to leak, and further cause the lithium battery in the vehicle to burn or even explode, thereby threatening the personal and property safety. Therefore, it is necessary to discover the danger in time after the battery catches fire, and to extinguish the fire at the fastest speed to ensure the personal and property safety.

[0003] To solve the above problems, an automatic fire extinguisher special for electric bicycles is needed to extinguish the fire occurring when the electric vehicle is charging or parking. CONTENT OF THE UTILITY MODEL

[0004] The utility model solves the technical problem of overcoming the defects of the above-mentioned technology, and provides an automatic fire extinguisher special for electric bicycles.

[0005] To solve the above-mentioned technical problem, the utility model provides the technical scheme of an automatic fire extinguisher special for electric bicycles: including a fire extinguisher bottle and a fire extinguishing agent arranged in the fire extinguisher bottle; the fire extinguishing agent adopts an ammonium phosphate salt dry powder fire extinguishing agent, a sealing plate is fixedly arranged at the nozzle opening of the fire extinguisher bottle; the sealing plate melts after being heated to a set temperature, and the fire extinguishing agent is sprayed out of the fire extinguisher bottle through the nozzle.

[0006] Further, the sealing plate adopts a tin-bismuth alloy plate, in which the tin accounts for 52%, and the bismuth accounts for 48%.

[0007] Further, an outlet valve is arranged at the bottle opening of the fire extinguisher bottle.

[0008] Further, a handle is arranged at the top of the fire extinguisher bottle.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] 1. Small in size and portable on the electric bicycle;

[0011] 2. When the fire occurs, the fire can be automatically extinguished to ensure the personal and property safety;

[0012] 3. Simple structure, easy to mass produce and manufacture, low in production and manufacturing cost, and suitable for popularization and application. BRIEF DESCRIPTION OF DRAWINGS

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Embodiment 1, in combination with the attached Figures 1-2 , the automatic fire extinguisher special for electric bicycle, including fire extinguisher bottle 1, set in fire extinguisher bottle 1 fire extinguishing agent;The fire extinguishing agent adopts ammonium phosphate salt dry powder extinguishing agent, the nozzle mouth of the fire extinguisher bottle 1 is sealed and fixedly provided with sealing plate 2;The sealing plate 2 is melted after reaching the set temperature by heating, and the fire extinguishing agent is sprayed out of the fire extinguisher bottle 1 through the nozzle.

[0019] In the specific implementation of the utility model, when the electric vehicle is charging, the charger is placed below the nozzle of the fire extinguisher, and when the charger is on fire, the temperature around the fire extinguisher will rise rapidly, the high-temperature smoke makes the temperature of the sealing plate 2 rise, and when the temperature rises to a certain temperature, the sealing plate 2 melts, and the fire extinguishing agent sprayed out of the nozzle of the fire extinguisher bottle 1 forms a fire barrier to prevent the spread of fire and cause major accidents.

[0020] In the specific embodiment, the sealing plate 2 is made of tin-bismuth alloy plate, wherein the tin is 52% and the bismuth is 48%, the sealing plate 2 is 2mm thick, and the sealing plate 2 is pasted to the nozzle with epoxy resin glue, and when the temperature rises above 138℃, the sealing plate 2 melts.

[0021] In the specific embodiment, the capacity of the fire extinguisher bottle 1 is not less than 1kg.
