[0038] Specifically, the rotating smoke jetting assembly further includes a motor 18, a transmission gear mechanism 17 and an axial flow fan 19. The motor 18 is fixed to the side wall of the body 03.

The bearing is a sealed deep groove ball bearing, which ensures smooth rotation and prevents smoke leakage.

[0040] Referring to Figure 4 As can be seen, the bottom of the smoke jetting port is fixedly connected with the smoke jetting port gears 21, which are mutually meshed with the motor gears 20 in the transmission gear mechanism 17. The transmission gear mechanism 17 includes mutually meshing motor gears 20 and smoke jetting port gears 21.

The lower end of the connecting pipeline is sealingly connected to the top opening of the filter chamber 09 through a flange to ensure the sealing property, and the upper end is rotationally connected to the bottom of the rotary smoke outlet 10 through a bearing. An axial flow fan 19 is arranged in the connecting pipeline, and the axial flow fan 19 is located between the filter chamber 09 and the rotary smoke outlet 10, with the air outlet facing the rotary smoke outlet 10.

[0042] Specifically, the power supply assembly further comprises a control system 24, the control system 24 comprises an antenna 23, the antenna 23 is arranged inside the filter chamber 09 and is electrically connected with the battery 22, and the solar panel 11 is respectively electrically connected with the battery 22 and the control system 24 to realize storage and distribution of solar electric energy.

[0043] The control system 24 is further connected with a temperature sensor, a humidity sensor and a wind speed sensor, and the temperature sensor, the humidity sensor and the wind speed sensor are all fixed to the outer side wall of the first support frame 02 and are all electrically connected with the control system 24.

[0044] Referring to Figure 5 It can be seen that the solar panel 11 is arranged at the top of the first support frame 02, and the solar panel 11 is respectively electrically connected with the battery 22 and the control system 24 through wires to ensure the reliability of outdoor use. The battery 22 is arranged inside the rotary base 01, and the battery 22 is responsible for storing the electric energy collected by the solar panel 11 to provide power for the operation of the entire device. The control system 24 is electrically connected with the battery 22 and has functions of data acquisition, signal processing and instruction output.

[0045] The control system 24 is connected with an antenna 23, the antenna 23 is arranged inside the filter chamber 09 and is used for receiving and sending wireless signals, so that remote monitoring and parameter setting can be realized. The control system 24 is electrically connected with the temperature sensor, the humidity sensor and the wind speed sensor to collect environmental parameters in real time.

[0046] Specific working process: after the smoke machine is assembled, it is placed in the orchard at a suitable position, the solar panel 11 absorbs solar energy in the daytime and converts it into electric energy, which is stored in the battery 22 to provide power for the operation of the device. The control system 24 receives the environmental parameters collected by the temperature sensor, the humidity sensor and the wind speed sensor in real time, and the device is in standby state, at this time the rotary smoke outlet 10 is stationary, and the axial flow fan 19 and the electric heating wire igniter 14 do not work. The user can connect the control system 24 through a remote terminal to set the temperature threshold, humidity threshold and wind speed threshold of the frost prevention work, and the control system 24 will monitor and judge according to the set parameters.

[0047] When the temperature sensor monitors that the ambient temperature drops below the set threshold, a signal is transmitted to the control system 24, and the control system 24 starts the anti-frost working procedure. First, the control system 24 controls the electric heating wire igniter 14 to be powered on to generate heat, ignites the cigarette 12, and the biological carbon and plant oil type smoke agent in the cigarette 12 burns to generate a large amount of smoke. Subsequently, the control system 24 starts the axial flow fan 19, and the smoke enters the filter chamber 09 under the suction of the axial flow fan 19. The large-particle smoke dust that is not fully burned is blocked by the filter screen 15, and the fine smoke particles pass through the filter screen 15 and are transported to the upper end of the connecting pipeline under the thrust of the axial flow fan 19.

[0048] At the same time, the control system 24 starts the motor 18, the motor 18 drives the motor gear 20 to rotate, drives the smoke outlet gear 21 to rotate through gear meshing, and then drives the rotating smoke outlet 10 to realize 360° continuous rotation. The smoke is uniformly sprayed from the smoke outlet, forming a circular smoke coverage area with the smoke machine as the center.

[0049] In the working process, the control system 24 automatically adjusts the rotating speed of the axial flow fan 19 according to the wind speed data collected by the wind speed sensor. When the wind speed is large, the rotating speed of the fan is increased to increase the smoke spraying amount, so as to ensure that the smoke can effectively cover the target area. When the wind speed is small, the rotating speed of the fan is appropriately reduced to reduce energy consumption.

[0050] When the temperature sensor monitors that the ambient temperature rises above the set threshold, a signal is transmitted to the control system 24, and the control system 24 successively closes the electric heating wire igniter 14, the axial flow fan 19 and the motor 18, and the rotating smoke outlet 10 stops rotating. The device returns to the standby monitoring state. If the data collected by the humidity sensor or the wind speed sensor exceeds the set safety threshold during the working process, the control system 24 will also automatically stop the device from working, so as to avoid damage or affect the anti-frost effect caused by the operation of the device in a harsh environment.

[0051] The above describes only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements that can be easily thought of by those skilled in the art within the technical range disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
