[0001] This utility model relates to the field of dual-duct fans, and more particularly to dual-duct purification laser fans. Background Technology

[0002] Dual-duct purification laser fan is an advanced air purification device. It adopts a dual-duct structure design to improve purification efficiency and reduce energy consumption. This device is usually equipped with a high-efficiency filtration system, which can effectively remove pollutants such as fine particulate matter, harmful gases and smoke from the air. The dual-duct technology makes the airflow distribution more uniform and reasonable, ensuring a wider air purification coverage and a higher clean air output rate, while maintaining the device's compact size and low noise level during operation.

[0003] Dual-duct purification laser fans are typically complex in design and large in size. Once the ventilation ducts are installed, their positions cannot be adjusted. This not only requires reconnecting the ducts but also consumes a lot of manpower and resources, affecting the pre-set airflow organization and purification effect. For scenarios that require frequent changes in work location or high flexibility in spatial layout, this undoubtedly increases the inconvenience and cost of use.

[0004] Therefore, considering that the aforementioned dual-duct purification laser fans are usually complex in design and large in size, and the ventilation ducts cannot be adjusted after installation, which not only requires reconnecting the ducts but also consumes a lot of manpower and resources, affecting the already set airflow organization and purification effect, a dual-duct purification laser fan can be designed. Utility Model Content

[0024] Please see Figures 1-5In this embodiment, a flange 12 is fixedly connected to the rear end of the inlet flexible hose 2, and the same flange 12 is fixedly connected to the rear end of the outlet flexible hose 3. The inlet flexible hose 2 and the outlet flexible hose 3 are connected to the external pipeline through the flange 12 to achieve ventilation. A fixing block 17 is fixedly connected to the right end of the fan body 1, and a motor 15 is fixedly connected to the right end of the fan body 1. The motor 15 provides kinetic energy, and a threaded rod 16 is fixedly connected to the output end of the motor 15. The motor 15 drives the threaded rod 16 to rotate, and the threaded rod 16 is rotatably connected to the fixing block 17. The fixing block 17 fixes the position of the threaded rod 16. A fixing block 13 is fixedly connected to the left end of the fan body 1. The fixing block 13 and the fixing block 17 respectively serve a fixing function. A fixing rod 14 is provided at the left end of the fan body 1. The fixing rod 14 is fixedly connected to the fixing block 13. A movable frame 18 is threadedly connected to the outer surface of the threaded rod 16. The movable frame 18 is connected to the fixing rod 1. 4. Sliding connection: The movable frame 18 slides on the fixed rod 14 to prevent positional deviation. The rotation of the threaded rod 16 drives the movable frame 18 to move downward on the fixed rod 14. Four pulleys 19 are fixedly connected to the bottom of the movable frame 18. Four support feet 20 are fixedly connected to the bottom of the fan body 1. Anti-slip pads 21 are fixedly connected to the bottom of the support feet 20. The pulleys 19 at the bottom of the movable frame 18 contact the ground to support the fan, making it easy to push the fan to move. When it moves to the appropriate position, the motor 15 drives the pulleys 19 to move upward and retract. The support feet 20 and anti-slip pads 21 ensure the stability of the fan body 1. A handle 22 is fixedly connected to the top of the fan body 1. An air inlet pipe 24 is fixedly connected to the front end of the fan body 1. An air outlet pipe 25 is fixedly connected to the front end of the fan body 1. By pushing the fan body 1 through the handle 22, the air inlet flexible hose 2 and the air outlet pipe 25 blow outdoor air into the room, and the air outlet flexible hose 3 and the air inlet pipe 24 blow indoor air out.

[0025] During operation, the inlet flexible hose 2 and the outlet flexible hose 25 blow outdoor air into the room, while the outlet flexible hose 3 and the inlet flexible hose 24 blow indoor air out. First, the inlet flexible hose 2 and the outlet flexible hose 23 are connected to the external pipeline via flange 12. When the fan body 1 needs to be moved, motor 6 is started to rotate the threaded rod 8. The rotation of the threaded rod 8 causes the upper storage frame 5 to move upwards on the limit rod 9. Then, the limit ring 11 is removed from the groove 10, and the inlet flexible hose 2 and the outlet flexible hose 24 are moved outwards. The second hose 3 is pulled out of the lower storage frame 4 to stretch and lengthen it, so as to avoid the fixed pipe restricting the movement of the fan body 1. Then the second motor 15 drives the second threaded rod 16 to rotate. The rotation of the threaded rod drives the moving frame 18 to move downward on the slide rod. The pulley 19 at the bottom of the moving frame 18 contacts the ground and supports the fan. The fan body 1 is pushed by the handle 22 and the pulley 19 to move the fan. When it moves to the appropriate position, the second motor 15 drives the pulley 19 to move upward and retract it. The support feet 20 and the anti-slip pads 21 ensure the stability of the fan body 1.

[0026] Through the above steps, when it is necessary to move the fan body 1, start the motor 6 to drive the threaded rod 8 to rotate. The rotation of the threaded rod 8 causes the upper storage frame 5 to move upward on the limit rod 9. Then, the limit ring 11 is taken out from the groove 10, and the air inlet telescopic hose 2 and the air outlet telescopic hose 3 are pulled out of the lower storage frame 4 to stretch and lengthen them. This avoids the fixed pipes restricting the movement of the fan body 1, thus solving the problem that dual-duct purification laser fans are usually complex in design and large in size. After the ventilation ducts are installed, their positions cannot be adjusted. This not only requires reconnecting the pipes, but also consumes a lot of manpower and resources, affecting the set airflow organization and purification effect.
