Description

Technical Field

[0001] The utility model relates to the technical field of electric smoke exhaust, in particular to a backpack-type hand-pushed integrated fire-fighting electric smoke exhaust device. Background Art

[0002] Fire-fighting electric smoke exhausters play a vital role in fire accidents. Their main task is to ensure the safe evacuation of personnel and reduce the harm of smoke to human health by effectively exhausting thick smoke and toxic gases. Existing fire-fighting smoke exhaust equipment usually consists of a motor, an impeller, an air inlet, an air outlet, a casing, etc., which can be quickly started by electric or manual control when a fire occurs to help exhaust high-temperature smoke and toxic gases in the room.

[0003] Although the existing electric smoke exhaust machines for fire fighting have been improved in terms of fire resistance, sealing and smoke exhaust efficiency, there are still many technical deficiencies in practical applications. First, most smoke exhaust equipment is designed for fixed installation, which is bulky and heavy, making it very inconvenient to carry and move, especially in complex or narrow environments, where it is difficult to operate flexibly. Second, the existing equipment generally lacks the folding function and cannot meet the needs of efficient storage and transportation under space-constrained conditions.

[0004] In order to deal with these problems, the market urgently needs a fire-fighting electric smoke exhaust device that is easy to carry and move and has a folding function. For example, although the portable smoke exhaust machine disclosed in CN212320002U improves the smoke exhaust efficiency through the dual-fan design, it has obvious limitations in storage and transportation because it cannot be folded. In addition, the drive motor is usually installed on the side of the fan and arranged outward. Even if the smoke exhaust machine is foldable, the drive motor will press against the body of the fan when the smoke exhaust machine is folded, thereby affecting the folding effect. In summary, there is a lack of a fire-fighting electric smoke exhaust device on the market that can effectively solve the problems of inconvenience in carrying and difficulty in folding. Utility Model Content

[0005] The problem to be solved by the utility model is that the existing electric fire smoke exhaust devices are not portable enough, lack folding function and are difficult to fold, and provide a backpack-type hand-pushed integrated electric fire smoke exhaust device.

[0011] Preferably, a support rod is provided at the bottom of the control box body, and an anti-slip and shock-absorbing washer is provided at the bottom of the support rod. The anti-slip and shock-absorbing washer can be made of polyurethane rubber, which provides good anti-slip and shock-absorbing effects during use, further improving the use safety of the equipment. Especially during use, in an environment where the fan generates large vibrations, the anti-slip and shock-absorbing washer can effectively reduce the risk of equipment displacement and maintain the stability of the device during operation.

[0012] Preferably, heat dissipation slot holes communicating with the inside of the control box body are provided in the positioning clamping groove, and the heat dissipation slot holes are evenly distributed from left to right. By providing the heat dissipation slot holes in the control box body, the heat dissipation performance of the equipment during long-term operation can be effectively improved, avoiding performance degradation or failure of the equipment caused by overheating. The evenly distributed design of the heat dissipation slot holes ensures smooth air circulation, thereby extending the service life of the equipment.

[0013] The beneficial technical effects achieved by the present utility model compared with the prior art are as follows:

[0014] 1. Improvement in portability and flexibility: The fan body of the present utility model makes an up-and-down flipping and opening / closing movement through the folding support mechanism. With the foldable support mechanism, the device can be easily folded and unfolded, facilitating carrying and use in different environments.

[0033] To facilitate the understanding of the above technical solutions of the present invention, the following provides a detailed description of the above technical solutions of the present invention through specific usage modes.

[0034] The present invention is a back-carrying and hand-pushing integrated fire-fighting electric smoke exhaust device, designed for smoke discharge at the fire scene. The specific working process is as follows:

[0035] 1. Preparation work:

[0036] Before using the device, the operator needs to select a suitable usage mode according to the on-site environment. This device provides two usage modes: back-carrying mode and hand-pushing mode. The back-carrying mode is suitable for use in narrow spaces, while the hand-pushing mode is suitable for quick movement in relatively spacious areas.

[0037] 2. Unfolding the device:

[0038] When the device needs to be used, the operator takes the device out of the storage position.

[0039] By unlocking the folding support mechanism 3, the operator moves the connecting plate 303 to drive the folding support bracket 301 upward, and unfolds the device from the folded state. At this time, the fan body 1 realizes up and down flipping through the folding support mechanism 3 and enters the working state.

[0040] Smoke exhaust operation:

[0041] The operator selects the usage mode according to the on-site needs and adjusts the position of the device. If in a narrow space, the operator can carry the device on the back; if in a relatively spacious environment, the operator can use the runner 502 of the flat-pushing component 5 to push the device to the target position.

[0042] After the target position is determined, the driving mechanism 2 is started. The driving motor 201 is powered by the power supply 202 to drive the blades in the fan body 1 to rotate, thereby generating a strong air flow to quickly discharge the high-temperature flue gas and toxic gases at the fire scene.

[0043] During the operation of the device, the heat dissipation slot holes 402 ensure that the heat in the control box body 4 can be effectively dissipated, avoiding the performance degradation or malfunction of the device caused by overheating.

[0044] Movement and adjustment:

[0045] If position adjustment is required at the fire scene, the operator can use the flat-pushing component 5 to quickly move the device without shutting down the equipment, or carry the equipment across obstacles through the backpack function.

[0046] In an environment with large vibrations, the anti-slip and shock-absorbing washer 7 at the bottom of the support rod 6 provides anti-slip and shock-absorbing effects, ensuring the stability of the equipment during operation and reducing the safety risks caused by the shaking or tipping of the equipment.

[0047] 5. Equipment storage:

[0048] After the smoke exhaust task is completed, the operator stops the operation of the driving mechanism 2 and waits for the equipment to completely stop running.

[0049] By folding the support mechanism 3, the equipment is folded back to its original position, and the fan body 1 is turned over and folded. The folded equipment has a smaller volume, which is convenient for storage and transportation.

[0050] During the folding process, the positioning clamping groove 401 on the control box body 4 will ensure the stable fixation of the driving mechanism 2, preventing the driving motor 201 from hindering the folding of the fan body 1 during folding. Finally, the device is stored in the storage location of the fire-fighting equipment for future use.

[0051] The negative hand-push integrated fire-fighting electric smoke exhaust device of the present utility model fully considers portability, operation convenience and equipment stability, and can provide an effective smoke exhaust function at complex and changeable fire scenes. Its folding structure and various usage modes enable the equipment to be applicable not only to general fire occasions, but also to special situations such as emergency rescue.
