Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a portable smoke exhaust fan for individual soldiers. Background Technology

[0002] Smoke is a major contributing factor to casualties during fires. Smoke contains a large amount of suspended toxic gases, causing serious damage to the respiratory system. Furthermore, smoke severely obstructs visibility, hindering evacuation. Even after firefighters enter the scene, the smoke can obscure the fire source, making it difficult to locate it promptly (not every firefighter carries infrared equipment, and dense smoke further impairs visibility). Therefore, smoke extraction not only aids in evacuation but also provides firefighters with a safer working environment. By rapidly removing smoke, reducing indoor temperature and smoke concentration, firefighters can more safely enter the fire scene for rescue and firefighting operations, while simultaneously creating a safer evacuation environment for those trying to escape.

[0003] Currently, smoke extraction mainly relies on large smoke extraction fans on fire trucks to draw smoke from buildings. However, this equipment is bulky, driven by a gasoline engine, and requires two firefighters to carry it to the rescue location. This wastes a lot of rescue resources, especially in complex spaces where it is cumbersome to move. Therefore, we have proposed a portable smoke extraction machine for individual firefighters to solve the above problems. Utility Model Content

[0004] This application provides a portable smoke exhaust machine for individual soldiers, which solves the problems of traditional large smoke exhaust machines, which have limited deployment during rescue operations, are cumbersome to move, difficult to operate, and waste rescue resources.

[0005] This application provides a portable smoke exhaust device for individual soldiers, including a battery unit, a connecting part detachably connected to the battery unit, a wire provided inside the connecting part, the wire being detachably connected to the battery unit, a handheld part fixed to the connecting part, an exhaust part fixed to one end of the handheld part, and the wire passing through the handheld part and electrically connected to the exhaust part.

[0006] The battery unit includes a battery base, on which a first limiting member for connecting and limiting and a first locking member for positioning are provided. The limiting plate is provided with a first electrical connection unit that is electrically connected to the battery in the battery base.

[0007] The connecting part includes a connecting seat, on which a second limiting member corresponding to the first limiting member and a second locking member corresponding to the first locking member are provided, and a second electrical connection unit electrically connected to the first electrical connection unit is provided inside the second limiting member;

[0008] The handheld unit includes a grip and a switch button;

[0009] The exhaust section includes an air duct, and a fan is installed inside the air duct via a support frame.

[0010] Preferably, the first limiting member is a limiting plate, the second limiting member is a limiting groove, and the limiting plate is slidably connected within the limiting groove.

[0011] Preferably, the limiting groove is a dovetail groove or a T-shaped groove.

[0012] Preferably, the first clip is a buckle, the second clip is a slot, and the buckle and the slot engage.

[0013] Preferably, the buckle is controlled by a buckle adjustment button.

[0014] Preferably, the connector is also provided with a safety button.

[0015] Preferably, the handgrip is provided with an anti-slip layer.

[0016] Preferably, the first electrical connection unit is an electrical connection groove, and elastic metal sheets connected to the battery are provided on both sides of the electrical connection groove. The second electrical connection unit is an electrical connection plug, and the electrical connection plug is located in the electrical connection groove and in contact with the elastic metal sheets.

[0017] Preferably, the bottom of the battery base is further provided with a fixing part.

[0018] Preferably, the fixing part is a vacuum suction cup or an electromagnet.

[0019] As can be seen from the above technical solution, this application provides a portable smoke exhaust fan for individual firefighters. When in use, this application is placed in a firefighter's backpack or fixed to a shoulder strap with Velcro. Upon entering a fire scene and encountering obstructed visibility, all ventilations are turned on immediately. One firefighter holds this application and is positioned in a location with outdoor ventilation, so that the air outlet of this application is directed towards the building with obstructed visibility, and the air inlet is directed towards the outside. Turning on this application can quickly exhaust smoke and dust from the area with obstructed visibility through positive pressure, facilitating the search for the fire source and rescue.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By setting limit parts and clips, the battery section and connecting part can be disassembled, which makes it easy to replace the battery in time when the battery power is low, so as to maintain the power of the exhaust section.

[0022] 2. With the electrical connection unit, the battery unit and the connection unit can be connected to achieve electrical connection. Once the electrical connection unit is connected, it can be used immediately, improving the starting efficiency after battery replacement.

[0023] In summary, this application utilizes a miniaturized ventilation device, allowing each firefighter entering a rescue operation to be equipped with one, enabling them to promptly ventilate smoke when visibility is obstructed. Carrying this application will not interfere with the firefighters' normal operations, nor will it excessively increase their burden. Furthermore, a certain number of these applications can be used for smoke venting at different points, further improving the efficiency and safety of the rescue process. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] See Figure 1-5This application discloses a portable smoke exhaust fan for firefighting smoke extraction operations. Specifically, it includes a battery unit 1, which is independently designed and can be equipped with batteries of different capacities to meet the weight control requirements of this application. Since the main weight of this application is in the battery unit 1, the specific weight should not affect the normal operation of the firefighter. The battery unit 1 is equipped with a power level indicator module, which can be designed as a percentage display screen or a certain number of lights to display power information through the number of lights. For details, please refer to the prior art. The battery unit 1 is detachably connected to a connecting part 2. When the battery power is insufficient, the battery unit 1 can be quickly disassembled and replaced with the connecting part 2 to ensure the continuous operation of this application. In the connection part 2, a wire is provided, which is detachably connected to the battery unit 1. A handheld part 3 is fixed on the connecting part 2. The size of the handheld part 3 can be designed according to the firefighter's usage habits, so as to be easy to grip and not easy to slip out of the hand. If necessary, an anti-slip layer can be added. An exhaust part 4 is fixed to one end of the handheld part. The wire passes through the handheld part 3 and is electrically connected to the exhaust part 4 to realize power supply. In this application, the exhaust section 4 primarily utilizes a high-volume model aircraft motor. Compared to a normal gasoline exhaust fan, which extracts smoke primarily through strong suction, resulting in a larger volume and smoke extraction area, this design addresses the limitations of fire truck space and on-site support due to the limited carrying capacity and bulky size. This application employs positive pressure for smoke extraction, meaning it achieves this by introducing a large volume of clean air into a space. The main purpose of this design is that, as a handheld device, the large-volume model aircraft motor allows for a significant airflow, but the small size limits extraction to a smaller, localized area. If traditional negative pressure extraction is used, the negative pressure loss is large and the purpose of smoke extraction cannot be achieved. Experiments have shown that small-sized fans with large air volume have a long blowing distance, which means they can blow a large amount of gas into a space, quickly increase the air pressure in the space, and achieve the purpose of smoke extraction. In specific experiments, in a prefabricated house, the smoke in the space can be exhausted to a visible level within 3-5 days. Therefore, although this application is small in size, its smoke extraction capacity is outstanding, and it is very easy to carry in a backpack or pocket. Everyone can carry one in fire fighting. This application can be produced in small batches by 3D printing or in large batches by injection molding by designing molds, so that this application can be rapidly popularized.

[0033] The battery unit 1 includes a battery base 11, within which a battery is fixed. The battery capacity can be designed according to different usage scenarios, and the power is set according to the motor power. Specific details regarding charging and power display can be found in existing technologies. The battery base 11 is equipped with a first limiting member for connection and a first locking member for positioning, enabling rapid positioning and fixing of the battery unit 1. The first locking member serves as a limit, cooperating with the first limiting member to achieve fixation. The limiting plate 15 is equipped with a first electrical connection unit that is electrically connected to the battery within the battery base 11. This first electrical connection unit serves as the battery's output terminal, connecting to the external environment.

[0034] The connecting part 2 includes a connecting seat 21, which corresponds to the battery base 11. Specifically, the connecting seat 21 is provided with a second limiting member corresponding to the first limiting member and a second locking member corresponding to the first locking member. In use, the second limiting member and the first limiting member cooperate to limit the position, and the first locking member and the second locking member engage to position and fix the device. The second limiting member is provided with a second electrical connection unit that is electrically connected to the first electrical connection unit and is connected to the battery in the battery part 1.

[0035] The handheld part 3 includes a handle 31 and a switch button 32. The handle 31 is designed to be gripped tightly. Since this application can increase the air volume, there will be a large thrust when the application is started, so the user needs to grip the application tightly. When in use, the application can be started by turning on the switch button 32.

[0036] The exhaust section 4 includes an air duct 41, which concentrates the air volume for blowing in the air. A fan 42 is installed in the air duct 41 through a support frame 43. In this application, the fan 42 is a model aircraft fan with a large exhaust volume, which can increase the air volume of the exhaust.

[0037] In this application, the first limiting member is a limiting plate 15, and the second limiting member is a limiting groove 24. The limiting plate 15 is slidably connected in the limiting groove 24. The limiting plate 15 can only slide in the limiting groove 24. The limiting plate 15 is inserted into the limiting groove 24 from one end for limiting. Specifically, the limiting groove 24 is a dovetail groove or a T-shaped groove.

[0038] In this application, the first locking element is a buckle 13, which can move downward elastically. The second locking element is a slot 22, and the buckle 13 and the slot engage. When the limiting plate 15 moves to one side under the push, the slot 22 and the buckle 13 move to the corresponding position, and the buckle 13 pops up to engage with the slot 22, connecting the battery part 1 and the connecting part 2. During disassembly, the buckle 13 is controlled by the buckle adjustment button 14. After the battery part 1 and the connecting part 2 are fixed, the buckle adjustment button 14 is located on one side of the battery part 1. By pressing the buckle adjustment button 14, the buckle 13 disengages from the slot 22, thereby releasing the locked state of the battery part 1 and the connecting part 2, and the battery part 1 can be disassembled.

[0039] In this application, to prevent accidental activation, a safety button 33 is also provided on the connector 21. The application can only be activated when the safety button 33 is pressed. That is, the safety button 33 and the switch button 32 are connected in series, and the application can only be activated when both are closed at the same time.

[0040] In this application, the first electrical connection unit is an electrical connection groove 12. Elastic metal sheets connected to the battery are provided on both sides of the electrical connection groove 12, and a contact space is formed between the elastic metal sheets. The second electrical connection unit is an electrical connection plug 23. The electrical connection plug 23 is located in the electrical connection groove 12 and is in contact with the elastic metal sheets. When the electrical connection plug 23 is inserted into the electrical connection groove 12, the elastic metal sheets deform, clamping the electrical connection plug 23 in the electrical connection groove 12, thereby improving the stability of the electrical connection.

[0041] In this application, in order to avoid firefighters holding this application in their hands all the time and wasting rescue resources, the bottom of the battery base 11 is also provided with a fixing part 16. The fixing part 16 is used to fix the application to a window or ventilation position. Specifically, the fixing part 16 is a vacuum suction cup or an electromagnet, so that the application can be attached to a smooth or ferromagnetic material.

[0042] As can be seen from the above technical solution, when using this application, it is placed in the firefighter's backpack or fixed to the shoulder strap with Velcro. Upon entering the fire scene and encountering obstructed visibility, all ventilations are opened immediately. One firefighter holds this application and is positioned in a location with outdoor ventilation, so that the air outlet of this application is directed towards the building with obstructed visibility, and the air inlet is directed towards the outside. Opening this application can quickly expel smoke and dust from the area with obstructed visibility through positive pressure, facilitating the search for the fire source and rescue. This application has a maximum thrust of 5KG at 3KW power, and the 16000mAh battery can last up to 6 hours, meeting the needs of fire rescue.

[0043] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope of this application is indicated by the claims.

[0044] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The embodiments of this application described above do not constitute a limitation on the scope of protection of this application.
