Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically a fire extinguisher with protective function. Background Technology

[0002] Fire extinguishers are essential fire-fighting equipment used to extinguish initial fires and are widely used in homes, industrial sites, and public buildings. Their main function is to extinguish fires by releasing an extinguishing agent to suppress the combustion process. Common types of fire extinguishers include dry powder fire extinguishers, carbon dioxide fire extinguishers, and foam fire extinguishers.

[0003] Among existing fire extinguisher designs, one example, a household fire extinguisher with protective features (publication number CN107929981B, published on October 26, 2021), achieves mobility and a certain degree of protection by incorporating a lifting and moving mechanism, a flexible nozzle, and fireproof canvas. However, this design is primarily aimed at household applications, its protective function is relatively limited, and its adaptability to complex fire scenarios is limited. Furthermore, this fire extinguisher exhibits weak automation, making it difficult to meet the demands of rapid response during a fire, thus restricting its performance in broader applications. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this invention provides a fire extinguisher with protective functions. By optimizing the structural design and adding an automated response mechanism, this fire extinguisher solves the problems of insufficient adaptability and low automation in complex fire scenarios of existing fire extinguishers.

[0005] A fire extinguisher with protective functions includes an outer casing, an inner storage tank, a triggering mechanism, a spray assembly, a protective cover, and a locking device. The outer casing has an inner storage tank inside for containing extinguishing agent. The inner storage tank is fixedly connected to the bottom of the outer casing by clips. Guide grooves are provided on both sides inside the outer casing, and these guide grooves slide against the side walls of the inner storage tank to ensure stable installation of the inner storage tank within the outer casing. A protective cover with a hemispherical structure is provided on the top of the outer casing, and its edge is fixedly connected to the top edge of the outer casing by bolts. A set of hinge seats is provided on both sides of the outer casing, and a spray assembly is located between the hinge seats on the same side.

The push rod passes through one side wall of the outer casing and is connected to the piston rod of the inner storage tank. The trigger button is located at the outer end of the push rod and is threaded to the side wall of the outer casing. A spring is installed between the push rod and the trigger button, and the spring is sleeved on the outside of the push rod to provide a restoring force. When the trigger button is pressed, the push rod pushes the piston rod of the inner storage tank, causing the extinguishing agent to be released from the inner storage tank and sprayed out through the spray assembly.

[0007] The locking device includes a latch, a pull rod, and a spring. Latches are located on both sides of the outer casing, with a pull rod slidingly attached to each latch. One end of the pull rod engages with the edge of the outer casing, while the other end is connected to the side wall of the outer casing via the spring. The spring, a compression spring, is sleeved on the outside of the pull rod to provide a restoring force. When it is necessary to open the outer casing, pulling the pull rod disengages it from the edge of the outer casing, thus releasing the locking device.

[0008] It also includes a baffle plate and a diversion pipe. The baffle plate is located on top of the inner storage tank and is arc-shaped. The edge of the baffle plate fits tightly against the inner wall of the inner storage tank to guide the flow direction of the extinguishing agent. The diversion pipe is located below the baffle plate. The inlet of the diversion pipe is connected to the outlet of the inner storage tank, and the outlet of the diversion pipe is connected to multiple nozzles of the spray assembly to achieve uniform distribution of the extinguishing agent.

[0009] It also includes a support frame, which is located at the bottom of the outer casing. The support frame has a cross-shaped structure, and its four ends are fixed to the bottom edge of the outer casing by bolts. Support plates are provided on both sides of the outer casing, and a shock-absorbing pad is provided at the center of the support frame. The shock-absorbing pad is made of rubber and is used to absorb the vibration generated by the fire extinguisher during movement or use.

[0010] Reinforcing ribs are provided on both sides of the inner side of the outer casing. The reinforcing ribs are L-shaped, with one end welded to the inner wall of the outer casing and the other end in contact with the outer wall of the inner storage tank, in order to enhance the overall strength of the outer casing.

[0011] This invention has the following advantages: By setting the outer casing as the main frame of the entire device, it provides solid physical protection for the internal components, effectively preventing damage to key components such as the inner storage tank from external impacts and compression. The inner storage tank is fixed to the bottom of the outer casing by buckles, and the guide grooves on both sides of the outer casing slide against the side walls of the inner storage tank, ensuring stable installation. L-shaped reinforcing ribs on both sides of the inner casing, with one end welded to the inner wall and the other end contacting the outer wall of the inner storage tank, enhance the overall strength of the outer casing and improve the durability of the fire extinguisher.

[0025] On both sides of the outer casing 1, there are spraying assemblies 4. Each spraying assembly 4 includes multiple nozzles with their outlets facing the external environment so that the extinguishing agent can cover a larger area. Each spraying assembly 4 is equipped with a valve 11 above it to control the amount of extinguishing agent sprayed. The number and layout of the nozzles in the spraying assembly 4 are designed according to actual usage requirements to ensure that the extinguishing agent can be evenly distributed and cover the target area.

[0026] Example 2

[0027] A triggering mechanism was added based on Embodiment 1. The triggering mechanism includes a push rod 6, a spring 7, and a trigger button 5.

[0028] Among them, such as Figure 4As shown. The push rod 6 passes through one side wall of the outer casing 1 and is connected to the piston rod of the inner storage tank 2. A trigger button 5 is provided at the outer end of the push rod 6. The trigger button 5 is threadedly connected to the side wall of the outer casing 1. A spring 7 is provided between the push rod 6 and the trigger button 5, and the spring 7 is sleeved on the outside of the push rod 6 to provide a restoring force.
