[0024] The direction adjustment component 2 includes a water supply ring 204. The water supply ring 204 is connected to one side of the spray gun barrel 1.

An adjustment lead screw 209 is drivingly connected inside the lead screw seat 208. The outer surface of the adjustment lead screw 209 is rotatably connected to a fixing frame. One side of the fixing frame is connected to one side of the water supply ring 204. One end of the adjustment lead screw 209 away from the lead screw seat 208 is connected to a transmission gear 210. A transmission gear ring 211 is meshingly connected to one side of the plurality of transmission gears 210. One side of the transmission gear ring 211 is connected to a driving gear ring 203. The driving gear ring 203 is rotatably connected to the outer surface of the water supply ring 204.

One end of the telescopic hose 205 away from the atomizing nozzle 206 is communicated with one side of the water supply ring 204.

[0025] The implementation method is specifically as follows: By setting the steering component 2, the driving motor 201 drives the atomizing nozzle 206 to deflect around the connecting seat through the driving gear 202, the driving gear ring 203, the transmission gear ring 211, the transmission gear 210, the adjusting lead screw 209, the lead screw seat 208 and the steering link 207, so that the atomizing nozzle 206 deflects, and thus the spraying direction and range of the atomizing nozzle 206 change. Through the cooperation of a plurality of atomizing nozzles 206 distributed in a ring and the linkage adjustment mechanism, the synchronous and precise control of the spraying angle of the atomizing nozzle 206 is realized. When the atomizing nozzle 206 deflects outwards, it has the advantages of uniform multi-directional coverage and dead-angle-free atomization diffusion. When the atomizing nozzle 206 deflects inwards, it concentrates the spraying to enhance the penetration power, realizing the dynamic matching of the spraying form and the coverage area, and being able to be well applied to various application scenarios such as dust removal and haze reduction, temperature reduction and humidity increase, and disinfection and epidemic prevention. The driving motor 201 is a self-locking motor and has a self-locking function when it stops rotating.

[0026] The flow stabilizing component 8 includes a housing 803 arranged at the central position inside the spray gun barrel 1.

One side of the housing 803 is rotatably connected with a rotating circular block 804. The outer surface of the rotating circular block 804 is connected with a plurality of rotating flow stabilizing plates 802 distributed in a circumferential array. The other end of the rotating flow stabilizing plate 802 is in contact with the inner wall of the spray gun barrel 1. A cavity is formed inside the housing 803, and an adjusting motor 805 is fixedly installed in the cavity. One end of the output shaft of the adjusting motor 805 extends outside the cavity and is connected with one side of the rotating circular block 804.

[0027] The implementation method is specifically as follows: By setting the flow stabilizing component 8, the rotating circular block 804 and the rotating flow stabilizing plates 802 are driven to rotate, so that the rotating flow stabilizing plates 802 move from the position where they are in contact with the fixed flow stabilizing plates 801 to the central position between two fixed flow stabilizing plates 801, thereby increasing the number of flow stabilizing structures in the spray gun barrel 1, effectively improving the overall flow stabilizing effect on the wind force, significantly reducing the generation of air vortices, ensuring that the air flow is more stable and uniform, improving the working efficiency and accuracy of the spray gun, reducing energy consumption and noise at the same time, prolonging the service life of the equipment, being simple to operate and highly adaptable, and being applicable to various working conditions. The adjusting motor 805 is a self-locking motor and has a self-locking function when it stops rotating.

[0028] Working principle: When in use, the operator turns on the fixed motor 902 and the external water supply device 4. The external water supply device 4 conveys water source into the water supply ring 204 through the delivery hose 3, and makes the water source spray out after atomization through the atomizing nozzle 206. During this process, the drive motor 201 rotates, the drive motor 201 drives the drive gear 202 to rotate, the drive gear 202 drives the drive gear ring 203 to rotate, the drive gear ring 203 drives the transmission gear ring 211 to rotate, the transmission gear ring 211 drives the transmission gear 210 to rotate, the transmission gear 210 drives the adjustment lead screw 209 to rotate, the adjustment lead screw 209 drives the lead screw seat 208 to move, the lead screw seat 208 drives the steering link 207 to move, and the steering link 207 drives the atomizing nozzle 206 to deflect around the connecting seat, so that the atomizing nozzle 206 faces the deflection, thereby changing the spraying direction and range of the atomizing nozzle 206, so as to meet different rescue scenarios.

[0029] At the same time, the fixed motor 902 drives the rotating main shaft 908 to rotate, and the rotating main shaft 908 drives the second driving fan 906 to rotate. At this time, the limit disk 913 contacts the friction disk 917 on the lower connecting disk 914 driven by the movable cylinder 903, making the linkage disk 915 in a locked state. At this time, the fixed motor 902 drives the sun gear 911 to rotate through the rotating main shaft 908, the sun gear 911 drives the planetary gear 916 to rotate, the planetary gear 916 drives the linkage gear ring 910 to rotate, the linkage gear ring 910 drives the rotating sleeve 907 to rotate, the rotating sleeve 907 drives the first driving fan 905 to rotate, and the rotating direction of the first driving fan 905 is opposite to that of the second driving fan 906, making the first driving fan 905 and the second driving fan 906 rotate synchronously and in opposite directions, and conveying wind force into the spray gun barrel 1. When the movable cylinder 903 drives the limit disk 913 to move towards the upper connecting disk 909 side, and the limit disk 913 limits the side of the friction disk 917 on the upper connecting disk 909 side, making the linkage gear ring 910 in a locked state. At this time, the fixed motor 902 drives the sun gear 911 to rotate through the rotating main shaft 908, the sun gear 911 drives the planetary gear 916 to rotate on the linkage gear ring 910. Since the linkage gear ring 910 is in a locked state, the planetary gear 916 drives the linkage disk 915 to rotate in the limit groove seat 912. At this time, the first driving fan 905 is locked, and the second driving fan 906 drives alone to provide wind force.

[0030] When the wind force is too strong, the staff starts the adjustment motor 805. The adjustment motor 805 drives the rotating circular block 804 to rotate, and the rotating circular block 804 drives the rotating flow stabilizer plate 802 to rotate, causing the rotating flow stabilizer plate 802 that was originally in contact with the fixed flow stabilizer plate 801 to move to one side. The rotating flow stabilizer plate 802 rotates to the central position between the two fixed flow stabilizer plates 801, increasing the number of flow stabilizing structures in the spray gun barrel 1, thereby improving the overall flow stabilizing effect on the wind force and avoiding the occurrence of air vortices.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
