DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 5The utility model provides a technical solution: an electric portable fire smoke exhaust machine, including a smoke exhaust machine housing 1, a motor output end of which is provided at the rear end with an electric fan blade 2 installed through a rotating shaft, a water guide plate 3 is provided on the outer surface of the smoke exhaust machine housing 1, and a fixed nozzle 4 is provided on the inner surface of the water guide plate 3, the left and right sides of the smoke exhaust machine housing 1 are rotatably connected with a support plate 5 through a rotating shaft, and a universal wheel 6 is installed at the lower end of the support plate 5, a positioning component 7 is provided on the right side of the support plate 5, the fixed nozzle 4 is penetrated and arranged on the smoke exhaust machine housing 1, and eight fixed nozzles 4 are distributed at an angle on the water guide plate 3, and the water guide plate 3 is arranged as a hollow structure inside. The water guide plate 3 has a water inlet pipe 11 extending through the lower end thereof, the positioning assembly 7 includes a rotating disk 701 and a positioning rod 702, and the rotating shaft installed on the right side of the smoke exhaust machine housing 1 is connected to the rotating disk 701, and the rotating disk 701 is fitted with the positioning rod 702 through the engaging grooves provided at equal angles on the upper end thereof, the positioning assembly 7 also includes a fixing plate 703 and a positioning spring 704, and the right side of the support plate 5 is connected to the fixing plate 703, and the positioning rod 702 is slidably arranged on the fixing plate 703, the positioning rod 702 is connected to the positioning spring 704, and the positioning spring 704 is connected to the fixing plate 703;

[0023] When the smoke exhaust fan needs to be used, the motor installed at the rear end of the smoke exhaust fan housing 1 starts working, and the output end of the motor is connected to the electric fan blades 2 through the shaft. At this time, the electric fan blades 2 start to rotate to achieve the purpose of electric smoke exhaust. When the smoke exhaust angle needs to be adjusted, the positioning rod 702 is pulled. At this time, the positioning rod 702 starts to move away from the fixed plate 703. Because a positioning spring 704 is installed at the lower end of the positioning rod 702, the positioning spring 704 begins to be stretched and deformed until the positioning rod 702 no longer fits into the engaging groove provided on the rotating disk 701. At this time, the rotating disk 701 can be rotated. Because the rotating disk 701 is connected to the rotating shaft provided on the right side of the smoke exhaust fan housing 1, the smoke exhaust fan housing 1 starts to rotate. As the smoke exhaust fan housing 1 rotates, it starts to The angle of smoke exhaust of the electric fan blade 2 is adjusted to ensure a better smoke exhaust effect. When it is adjusted to the specified position, the positioning rod 702 is released. Under the action of the positioning spring 704 restoring its deformation, the positioning spring 704 begins to pull the positioning rod 702 downward, that is, the positioning rod 702 begins to move in the direction close to the rotating disk 701 until it fits with the engaging groove provided on the rotating disk 701. At this time, the position of the rotating disk 701 can be fixed, and the angle of the smoke exhaust machine housing 1 can be fixed after adjustment. In the process of smoke exhaust, pressurized water is introduced into the water guide plate 3 through the water inlet pipe 11 (the water inlet pipe 11 can be connected to the fire hose when in use). At this time, the fixed nozzle 4 provided on the water guide plate 3 can be used to spray and cool the discharged smoke, thereby reducing dust and impurities in the smoke.

[0024] A rotating assembly 9 is provided at the lower end of the support plate 5, and the rotating assembly 9 is interconnected with the pulling assembly 8, and a pulling rod 10 is installed at the upper end of the pulling assembly 8, the pulling assembly 8 includes an adsorption plate 801, an adsorption magnet 802 and a rotating pull plate 803, and the left and right sides of the support plate 5 are interconnected with the adsorption plate 801, and the adsorption plate 801 and the adsorption magnet 802 are mutually affixed, the adsorption magnet 802 and the rotating pull plate 803 are interconnected, and the upper end of the rotating pull plate 803 is interconnected with the pulling rod 10, the rotating assembly 9 includes a connecting shaft 901, a vortex spring 902 and a fixed sleeve 903, and the support plate 5 is interconnected with the connecting shaft 901 through bearings installed on its left and right sides, and the connecting shaft 901 is interconnected with the rotating pull plate 803, the connecting shaft 901 is interconnected with the vortex spring 902, and the vortex spring 902 is interconnected with the fixed sleeve 903, and the fixed sleeve 903 is installed on the support plate 5;

[0025] When the smoke exhaust machine housing 1 needs to be moved, the pull rod 10 is pulled. Since the pull rod 10 is connected to the rotating pull plate 803, the rotating pull plate 803 begins to rotate. Since the connecting shaft 901 is installed at the lower end of the rotating pull plate 803, the connecting shaft 901 begins to rotate. Since the connecting shaft 901 is connected to the vortex spring 902, the vortex spring 902 begins to be squeezed and deformed. As the rotating pull plate 803 rotates, the adsorption magnet 802 installed on the rotating pull plate 803 no longer fits with the adsorption plate 801. At this time, the rotating pull plate 803 and the pull rod 10 are in a tilted state, and then the support plate 5 is pulled by the universal wheel 6. The smoke exhaust fan housing 1 can be pulled and moved to ensure that the smoke exhaust fan housing 1 can be moved conveniently. After pulling, the pulling rod 10 is released, and under the action of the vortex spring 902 restoring the deformation, the vortex spring 902 begins to drive the rotating pull plate 803 to return to its original position until the adsorption magnet 802 installed on the rotating pull plate 803 is adsorbed and fit with the adsorption plate 801 (the adsorption plate 801 is set to be made of iron material, and the adsorption plate 801 can be mutually adsorbed with the adsorption magnet 802 set to be made of magnetic material), so as to achieve the purpose of automatically rotating and returning the rotating pull plate 803 and the pulling rod 10 for storage, which can effectively reduce the occupied area of ​​the smoke exhaust fan to improve the portability of the smoke exhaust fan.
