[0032] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] As Figure 1-8As shown in the figure, an electric fire fighting cannon includes a rotating base 1, a support 2, a connecting frame 3, a wind tube 4, a rotating shaft 5, a fan blade 6, a first driving member 7, a spraying device and an adjusting device. The rotating base 1 includes a base 11 and a turntable 12. The turntable 12 is rotatably connected to the base 11 and is controlled to rotate by a motor and a gear. The support 2 is fixed on the turntable 12. The connecting frame 3 is rotatably connected to the support 2 through the adjusting device. The wind tube 4 is fixed on the top of the connecting frame 3. The first driving member 7 is a conventional servo motor and is fixed to the tail end of the wind tube 4 through a fixing frame. The rotating shaft 5 is connected to the output shaft of the first driving member 7. The fan blade 6 is fixed on the rotating shaft 5 and is located inside the wind tube 4.

[0034] Specifically, the spraying device includes a connecting column 81, an atomizing ring 82, a sleeve 83, atomizing nozzles 84, a control mechanism and a water supply mechanism. The connecting columns 81 are evenly arranged at the end of the wind tube 4, and one end of each connecting column 81 is fixed to the end of the wind tube 4. The atomizing ring 82 is fixed on the connecting column 81, and a plurality of water outlet holes 821 are evenly formed in the atomizing ring 82. The sleeve 83 is sleeved on the atomizing ring 82, is rotatably connected to the atomizing ring 82, and is arranged corresponding to the water outlet holes 821. The sleeve 83 is provided with water outlet holes matching the atomizing nozzles 84, and the water outlet holes correspond to the water outlet holes 821. The control mechanism can control the rotation of the atomizing nozzles 84. By controlling the rotation of the atomizing nozzles 84 through the control mechanism, the atomizing nozzles 84 are rotated outwards to form a flared shape, thereby increasing the spraying range.

[0035] As a preferred solution, the control mechanism includes a control ring plate 851, a pressing block 852, a driving assembly and a reset assembly. The control ring plate 851 is sleeved outside the atomizing nozzle 84. The pressing blocks 852 are evenly fixed on the inner wall of the control ring plate 851, are arranged corresponding to the atomizing nozzles 84, and the pressing blocks 852 are provided with arc-shaped curved surfaces, and the atomizing nozzles 84 are attached to the arc-shaped curved surfaces. The driving assembly can drive the control ring plate 851 to rotate. The reset assembly cooperates with the sleeve 83 to enable the atomizing nozzles 84 to rotate outwards and reset. When it is necessary to reduce the spraying range, the control ring plate 851 can be driven to rotate by the driving assembly. As the control ring plate 851 rotates, the arc-shaped curved surface of the pressing block 852 will gradually press down the atomizing nozzles 84, so that the atomizing nozzles 84 rotate inwards, thereby reducing the spraying range. When it is necessary to increase the spraying range, the control ring plate 851 is reversely rotated by the driving assembly, and the reset assembly will drive the atomizing nozzles 84 to rotate outwards, thereby increasing the spraying range.

[0036] Specifically, the driving assembly includes a connecting rod 853, a driving ring plate 854, a rack 855, a second gear 856, and a third driving member 857. The driving ring plate 854 is sleeved on the outer wall of the air duct 4 and is rotatably connected to the air duct 4. One end of the connecting rod 853 is fixed to the driving ring plate 854, and the other end is fixed to the control ring plate 851. The rack 855 is fixed to the driving ring plate 854. The second gear 856 is a conventional gear, which is fixed on the output shaft of the third driving member 857 and meshes with the rack 855. The third driving member 857 is a conventional servo motor, which is fixed on the outer wall of the air duct 4. Starting the third driving member 857 will drive the second gear 856 to rotate, and the second gear 856 will drive the driving ring plate 854 to rotate, thereby driving the control ring plate 851 to rotate. The reset assembly includes a connecting rod 861, a fixing ring 862, and an elastic telescopic rod 863. One end of the connecting rod 861 is fixed to the connecting column 81. The fixing ring 862 is fixed to the end of the connecting rod 861, and the axis of the fixing ring 862 coincides with the axis of the atomizing ring 82. The elastic telescopic rod 863 is arranged corresponding to the atomizing nozzle 84. One end of the elastic telescopic rod 863 is hinged to the atomizing nozzle 84, and the other end is hinged to the fixing ring 862. Thus, the elastic telescopic rod 863 can push the atomizing nozzle 84 to rotate outwards. Of course, in other embodiments, the reset assembly can also use a torsion spring. The torsion spring is sleeved on the atomizing ring 82, and one torsion arm is fixed to the sleeve 83, and the other torsion arm is fixed to the atomizing ring 82.

[0037] Specifically, the water supply mechanism includes an infusion pump 871, a connecting hose 872, a water inlet pipe 873, a delivery pipe 874, and a filtering assembly. The infusion pump 871 is fixed on the turntable 12 and is used to deliver liquid to the atomizing ring 82. One end of the connecting hose 872 is connected to the infusion pump 871, and the other end is connected to the atomizing ring 82. One end of the water inlet pipe 873 is connected to the infusion pump 871, and the other end is connected to the delivery pipe 874 through the filtering assembly.

[0038] As a preferred solution, the filtering component includes a filter box 881, a first flange 882, a second flange 883, a filter screen 884, a mounting plate 885, a rotating shaft 886, a paddle 887 and an elastic scraper 888. Water passing holes are formed on both sides of the filter box 881. The first flange 882 is fixed to the ends of the conveying pipe 874 and the water inlet pipe 873. The second flange 883 is fixed to both sides of the filter box 881 and can be connected to the first flange 882 by bolts. The filter screen 884 is fixed to the inner wall of the water passing hole. The two ends of the mounting plate 885 are fixed to the inner wall of the conveying pipe 874. One end of the rotating shaft 886 is rotatably connected to the mounting plate 885. The paddle is fixed to the rotating shaft 886. The elastic scrapers 888 are evenly fixed to the rotating shaft 886 and the elastic scrapers 888 are in contact with the filter screen 884. When the liquid infusion pump 871 extracts liquid, the liquid will flow rapidly in the conveying pipe 874. The flowing liquid drives the paddle to rotate, and then drives the rotating shaft 886 to rotate. The rotating shaft 886 drives the elastic scrapers 888 to slide on the filter screen 884, so as to clean the filter screen 884 in time and ensure the water passing efficiency of the filter screen 884.

[0039] In other embodiments, the filtering component further includes a collecting plate 891, a first guide plate 892, a second guide plate 893 and a baffle 894. The collecting plate 891 is fixed to the inner wall of the filter box 881. The collecting plate 891 and the inner wall of the filter box 881 can enclose a collecting cavity. A sewage discharge port is formed at the bottom of the filter box 881, and a switch is provided at the sewage discharge port. The first guide plate 892 is fixed to the collecting plate 891 in an inclined downward manner. The second guide plate 893 is fixed to the inner wall of the filter box 881 in an inclined downward manner and is arranged in a staggered manner with the first guide plate 892. The baffles 894 are evenly fixed to the bottom surfaces of the first guide plate 892 and the second guide plate 893. Then, during the rotation process, the elastic scraper 888 will contact the scraper, and then scrape off the impurities on the scraper, ensuring the cleaning effect of the elastic scraper 888. And during the rotation process of the elastic scraper 888, it will drive the water flow on one side of the filter box 881 to flow downward, and then drive the impurities to move into the collecting cavity. And under the restriction of the first guide plate 892 and the second guide plate 893, the impurities entering the collecting cavity can be reduced from flowing out again.

[0040] Specifically, the adjusting device includes a connecting shaft 91, a driving plate 92, a first gear 93 and a second driving member 94. The connecting shaft 91 is fixed to the connecting frame 3, and its two ends are rotatably connected to the bracket. The driving plate 92 is fixed to the connecting shaft 91, and the driving plate 92 is provided with teeth that cooperate with the first gear 93. The second driving member 94 is a conventional servo motor, which is fixed to the turntable 12. The first gear 93 is a conventional metal gear, which is fixed to the output shaft of the first driving member 7 and meshes with the teeth of the driving plate 92. Then, starting the first driving member 7 to drive the first gear 93 to rotate can drive the driving plate 92 to rotate, and then drive the air duct 4 to rotate, so as to adjust the spraying angle.

[0041] In other embodiments, a housing 10 is sleeved and fixed on the hair dryer 4. A fire detector 101 is provided at the top of the housing 10.
