Description

Technical Field

[0001] This utility model relates to the field of fire rescue equipment technology, specifically a handheld hornet's nest fire attack device for firefighting. Background Technology

[0002] Wasps, also known as hornets, are widely distributed, fast-flying insects. When attacked or disturbed, they will swarm and attack, potentially causing allergic and toxic reactions in humans. In recent years, firefighters have received numerous calls for help to remove wasp nests during their daily work. Due to the inherent danger of wasp nests, firefighters must wear protective bee suits. The removal process is challenging because wasp nests are typically located on tall buildings, in confined spaces, or in trees. Furthermore, the varying locations and types of wasp nests present significant difficulties and dangers during the removal process.

[0003] Conventional methods can only remove the nest, but the wasps remain alive. This poses a significant risk of wasps escaping and stinging people, and they may continue to build nests, failing to address the root cause of the problem. While some areas use wasp guns, their effectiveness is poor, often resulting in wasps flying out during removal and causing stings to firefighters while eliminating the nest.

[0004] A search revealed two patent documents: CN216315017U, which discloses a handheld wasp nest burner for firefighting; and CN222967754U, which discloses a fire-attack device for removing wasp nests. These two patent documents offer fire-attack devices for wasp nests from different perspectives. Providing an easy-to-use fire-attack device is essential for firefighters to facilitate the timely removal of wasp nests during rescue operations. Utility Model Content

[0027] Furthermore, the handheld wasp nest fire-fighting device provided in this embodiment contains an insecticide for wasp eradication in the agent bottle 5. This insecticide is a commercially available, low-toxicity, highly effective, and environmentally friendly product, and is a flammable liquid. The insecticide in the agent bottle 5 is a commonly used agent that can be purchased directly from the market. When needed, it is placed directly in the bottle holder 4 and then secured with the straps 7. Example 2

[0028] This embodiment, based on Embodiment 1, improves ease of use by enabling telescopic adjustment of the handheld rod 1. It employs a handheld fire-fighting honeycomb fire-starting device provided in this embodiment. The handheld rod 1 is composed of multiple tubular bodies 11 with gradually decreasing diameters nested together to form a telescopic rod structure, with fastening nuts 12 at the connection points of adjacent tubular bodies 11. The handle 6 is connected to the tubular body 11 at the rear end of the handheld rod 1 via a screw connection, while the support frame 32 in the pressing assembly 3 is connected to the tubular body 11 at the front end of the handheld rod 1 via a plug-in connection. This telescopic structure facilitates adjustment of the length of the handheld rod 1. Furthermore, the universal joint bracket 321 in the support frame 32 is connected to the tubular body 11 at the front end of the handheld rod 1 via a plug-in connection, facilitating adjustment of the angle of the support frame 32. Example 3

[0029] This embodiment is based on Embodiment 2. Since the finished product specifications of the medicine bottles 5 purchased directly from the existing market vary, a handheld fire-fighting honeycomb fire-starting device provided in this embodiment is used to enable pressing operations on medicine bottles 5 of different heights. Multiple adjustment holes corresponding to the connecting rod are provided in the first support plate, the second support plate, and the pressing member 33. The pressing member 33 is connected to the connecting rod through the adjustment holes in the pressing member 33. By using the adjustment holes in the first support plate, the second support plate, and the pressing member 33, and connecting to the connecting rod through the adjustment holes in the pressing member 33, the length of the pressing member 33 located on one side of the medicine bottle 5 can be adjusted, thereby satisfying the pressing operation on medicine bottles 5 of different heights.

[0030] The handheld fire-fighting device for wasp nests described in this utility model uses a power supply 21, ignition switch 22, igniter 23, ignition needle 24 and charging interface 25, which are all commonly used devices in the prior art and can be purchased directly from the market according to design requirements. The medicine bottle 5 can be purchased directly from the market as a finished product.

[0031] In actual use, when needed, multiple tubes 11 with gradually decreasing diameters are assembled sequentially using the fastening nut 12 to form the handrail 1. The handle 6 is then screwed to the rear end of the handrail 1, and the universal joint bracket 321 in the support frame 32 is inserted into the tube 11 at the front end of the handrail 1 to complete the assembly. As for the pull rope 31, one end is positioned at the front end of the handrail 1 for easy operation. The other end of the pull rope 31 is first wound around the single pulley 35, and then connected upwards to the pressing member 33. In use, the pull cord 31 is pulled by hand. Since the other end of the pull cord 31 is connected to the pressing member 33 near the medicine bottle 5 via a single pulley 35, under external force, the pull cord 31 drives the pressing member 33 to rotate along the connecting rod mounted on the first and second support plates. As the pressing member 33 rotates downwards, it presses down on the medicine bottle 5, causing the medicine inside the bottle 5 to spray out from the atomizing nozzle. Simultaneously, the ignition switch 22 is activated, igniting the sprayed medicine through the ignition needle 24, thus achieving the purpose of fire attack. After the fire attack on the wasp nest is complete, the pull cord 31 is released. Under the action of the return spring 34, the pressing member 33 moves upwards, separating from the medicine bottle 5.

[0032] Therefore, the handheld fire-fighting device for wasp nests described in this utility model utilizes a pressing component 3 mounted on the hand handle 1. The pressing component 33 rotates within the support frame 32 via a pull rope 31, facilitating the pressing of different sized medicine bottles 5. This allows the medicine in the bottles 5 to be sprayed out. Simultaneously, the sprayed medicine is ignited by the ignition needle 24 under the action of the ignition component 2, achieving the purpose of fire suppression. Furthermore, the power supply 21 of the ignition component 2 is housed within the handle 6, simplifying its overall structure. Additionally, the hand handle 1 adopts a telescopic structure, enabling efficient handling of wasp nest incidents in situations where people cannot reach them, such as under eaves or on trees.

[0033] In summary, the fire attack device described in this utility model can be retracted when not in use, and can be used after assembly when needed. It is not only easy to adjust its length, but also allows for pressing operations on medicine bottles 5 of different sizes, thereby meeting the needs of various hornet nest disaster handling work. Its overall structure is simple, easy to assemble and carry, convenient to operate, highly practical, and easy to promote and use.

[0034] Other aspects of this utility model that are not detailed herein are all conventional techniques known to those skilled in the art.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Various modifications and variations can be made by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made using the present utility model should be included within the protection scope of the present utility model.
