Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, and in particular to a thermal aerosol fire extinguisher. Background Technology

[0002] A fire extinguisher is a tool used to extinguish fires. It contains chemicals to put out fires. Fire extinguishers are common fire prevention facilities, stored in public places or areas where fires may occur. Different types of fire extinguishers contain different components, designed specifically for different types of fires. Users must be careful when using them to avoid adverse effects and potential dangers. One type of fire extinguisher is the thermal aerosol extinguisher. When a fire occurs, a certain ignition structure ignites the propellant. The heat generated by the combustion of the propellant vaporizes the thermal aerosol and sprays it out. The sprayed thermal aerosol gas covers the fire source, depriving it of oxygen and thus extinguishing the fire. A conventional thermal aerosol fire extinguisher is disclosed in patent application CN201810031343.2, filed on January 12, 2018, entitled "A Handheld Fire Extinguisher and Extinguishing Method".

[0003] However, existing fire extinguishers that use thermal aerosols as extinguishing agents have a single outlet for discharging the extinguishing agent, resulting in a small dispersion angle and low extinguishing efficiency. Utility Model Content

[0004] The present invention aims to provide a thermal aerosol fire extinguisher with a large dispersion angle when the extinguishing agent is output, thereby solving the problem of small dispersion angle of the extinguishing agent in existing thermal aerosol fire extinguishers that output extinguishing agent from a single hole.

[0005] The above technical problems are solved by the following technical solution: A thermal aerosol fire extinguisher includes a fire extinguisher cylinder and an extinguishing agent stored in the fire extinguisher cylinder. The fire extinguisher cylinder is equipped with an extinguishing agent output head. The extinguishing agent output head is characterized by having a main output channel, a central nozzle connecting the main output channel to the outside of the extinguishing agent output head, and several concentric rings of peripheral nozzles connecting the main output channel to the outside of the extinguishing agent output head. Each ring of peripheral nozzles surrounds the central nozzle, and each ring of peripheral nozzles is located on a circumference. The circle containing one ring of outward-facing nozzles surrounds the circle containing another ring of peripheral nozzles. This allows the sprayed extinguishing agent to disperse sufficiently.

[0006] Preferably, the central nozzle has a straight structure, and its opening direction is the same as the opening direction of the output end of the main output channel, while the peripheral nozzles have an arc-shaped structure. This allows the extinguishing agent to spread out at a greater angle during output.

[0007] Preferably, the opening direction line of the main outlet channel is tangent to the circle containing the peripheral nozzles. This improves the flow of extinguishing agent from the main outlet channel into the peripheral nozzles.

[0008] Preferably, the circles containing all the peripheral nozzles are located on a plane perpendicular to the opening direction of the output end of the main output channel. This allows for a larger dispersion angle of the extinguishing agent output.

[0009] Ideally, the circumference of each outer nozzle should be concentric. This ensures a more uniform distribution of the extinguishing agent.

[0010] Preferably, the fire extinguisher casing is a cuboid formed by a bottom wall, a top wall, a front side wall, a rear side wall, a left side wall, and a right side wall. The front and rear sides of the bottom wall, the front and rear sides of the right side wall are each provided with connecting edges, and bolt mounting channels are provided on these connecting edges. This improves the stability during installation and fixing.

[0011] Preferably, the bolt is a bolt hole or a notch according to the channel.

[0012] Preferably, the bolt hole is provided with an elastic washer, which includes an outer connecting piece, an inner connecting piece, a first elastic bending portion, and a second elastic bending portion. The first elastic bending portion connects one end of the outer connecting piece to one end of the inner connecting piece, and one end of the second elastic bending portion connects to the other end of the inner connecting piece. The other end of the second elastic bending portion connects to the connecting edge. The inner connecting piece has an inner connecting piece bolt hole, and the outer connecting piece has an outer connecting piece bolt hole aligned with the inner connecting piece bolt hole. This alignment ensures that the bolt is not easily loosened, and the elastic washer is accurately positioned and will not shift.

[0013] Preferably, the outer connecting piece, the inner connecting piece, the first elastic bending portion, and the second elastic bending portion are integrally formed together, with the second elastic bending portion integrally formed with the connecting edge. This ensures convenient installation and reliable connection.

[0014] Preferably, the outer connecting piece is parallel to the connecting edge. This ensures good uniformity of force distribution on the bolts during connection.

[0015] This invention has the following advantages: it provides a large dispersion angle when discharging the extinguishing agent; and it is secure and reliable when installed. Attached Figure Description
