[0023] See also Figures 1 to 4 A compressed air driven air-blast type fog cannon comprises a fog cannon body 1, a water outlet assembly 2 arranged at the front end of the fog cannon body 1, a fan assembly 3 arranged at the end of the fog cannon body 1, and an air compressor 4 connected to the fog cannon body 1 and used to drive the fan assembly 3 to rotate.

[0024] The compressed air driven air-supplied fog cannon of the present application adopts an air compressor as the driving source to replace the traditional electric motor, blows the fan assembly to rotate, and then cooperates with the water outlet assembly to achieve the spray effect, fundamentally avoiding the risk of explosion accidents caused by electric sparks. This innovative design not only improves the safety of mine operations, but also enables the water mist to be diffused over long distances and over a large area, improves the working environment, and ensures safe production in mines.

[0025] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the outer wall of the fog cannon body 1 is provided with an air inlet 5, the inner wall of the fog cannon body 1 is provided with an air outlet 6 corresponding to the fan assembly 3, and the air compressor 4 is connected to the air inlet 5 through a soft pipe 7.

[0026] In this embodiment, multiple air inlet holes can be provided, and the number of soft pipes corresponds to the number of air inlet holes, so that the air compressor can directly provide the required airflow for the fog cannon, while reducing energy consumption. By effectively utilizing the airflow generated by the compressor, the performance and stability of the fog cannon are improved, and its dust reduction effect and safety performance are further improved, wherein the soft pipe is a plastic pipe, a rubber pipe, or a leather pipe.

[0029] Furthermore, as a preferred implementation mode of the present solution but not a limitation, the fog cannon body 1 includes a mounting portion 12 for mounting the fan assembly 3 , and the air outlet 6 is correspondingly arranged on the inner side wall of the mounting portion 12 .

[0032] In this embodiment, the transmission path of the airflow can be effectively optimized, thereby improving the dust reduction effect and operating stability of the fog cannon.

[0035] Furthermore, as a preferred implementation of the present solution but not a limitation, adjacent atomizing nozzles 23 are arranged at equal intervals.

[0036] In this embodiment, it is possible to ensure that the atomizing nozzles evenly distribute the atomized water mist in the coverage area, effectively avoiding blind spots or mist leakage caused by uneven atomization coverage. By setting the nozzles at equal intervals, full coverage of the entire operation area can be achieved, improving the overall and consistency of the dust reduction effect.
