[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This utility model relates to a fourth-generation hot air antifreeze device, which includes a fan device.

[0023] The fan unit includes an atomizing chamber, with a blower fan installed at one end and a spray device installed at the other end;

[0024] The fan unit is rotatably connected to a hollow three-dimensional support frame, and a support frame is rotatably connected to the outer wall of the fan unit. The support frame is connected to the support frame, and a gap is formed between the fan unit and the support frame, which allows the fan unit to pass through.

[0027] 1. The equipment uses a fan to turbulent airflow, neutralizing ground temperature to achieve a frost-proof effect. The fourth-generation hot air anti-freeze device is typically installed at a height of 6 to 8 meters, where the temperature is highest. Utilizing the gravity and pressure of the mist, it rapidly blows relatively warm air from higher altitudes towards the fruit trees. This creates convection between the relatively warm air and the cool air at lower altitudes, raising the temperature of the lower atmosphere and increasing the overall vegetation temperature by 2 to 3 degrees Celsius. Compared to traditional methods that rely solely on blowing air without the pressure and gravity of the mist, this method quickly replaces cold air with relatively warm air, increasing efficiency by 2 to 3 times. During the high temperatures of spring, activating the fourth-generation hot air anti-freeze device can lower the temperature, thus ensuring fruit set in the orchard. During the high temperatures of summer, activating the fourth-generation hot air anti-freeze device increases airflow, effectively improving the quality of the fruit in the orchard.

[0028] 2. The fan unit is rotatably connected to the support frame, and the gap between the fan unit and the support frame allows the fan unit to pass through, thus enabling fully automatic 360-degree unlimited rotation of the fan unit. The rotation angle can also be set to any angle from 0 to 360 degrees according to the actual terrain. It automatically oscillates up and down, for example, from 10 to 30 degrees, to achieve a wave-like airflow for optimal anti-frost effect. Automatic start / stop can also be set at a set temperature.

[0029] 3. Add antifreeze to the water in the tank, and before the cold air arrives, use the fourth-generation hot air antifreeze device to blow it onto the vegetation, especially fruits and vegetables, to prevent them from freezing and causing heavy losses. This can achieve a better frost protection effect.

[0030] In summary, this effectively addresses the problem of quickly dispelling or raising the air temperature when cold air has just arrived and the air temperature is not yet very low, thus providing excellent frost and freeze protection without causing unnecessary waste.

[0057] A further preferred embodiment: The bottom of the bracket 4 is equipped with a moving device 9 having a braking function, and the water tank 7 is mounted on the moving device 9.

[0058] Further preferred: the bracket 4 is made of a telescopic rod with telescopic function, and the height of the bracket 4 is 1 meter to 10 meters.

[0059] The basic working principle of this utility model is as follows: During operation, the water in the water tank 7 is pressurized by the high-pressure pump 10 through the water supply pipe 6 to the spray head 8, and then refined into a fine water stream through the spray hole 81 of the spray head 8 and sprayed towards the blower fan 2. The blower fan 2 blows the fine water stream sprayed from the spray hole 81 towards the spray device 3. The water stream is further refined through the cavity 312 of the spray chamber 31 of the spray device 3, and finally atomized and sprayed out after being granulated by the spray head 32.

[0060] Example 1:

[0061] Under the operation of the high-pressure pump 10, the water in the water tank 7 quickly enters the water inlet pipe 6 and then quickly enters the spray head 8 in the atomization chamber 1 for initial atomization. Under high pressure, the water in the spray head 8 is atomized into fine water through the spray hole 81 to complete the secondary atomization. The fine water sprayed from the spray hole 81 is sprayed towards the blower fan 2. The blower fan 2 blows the fine water towards the spray device 3 at high speed. The fine water is atomized for the first time through the cavity 312 of the spray chamber 31, and then atomized again through the spray head 32 before being completely atomized and sprayed out.

[0062] Water tank 7 is installed at the bottom of bracket 4 for easy water replenishment.

[0063] The spray chamber 31 is cylindrical, and the spray heads 32 are evenly installed on the outer edge of the spray chamber 31. The nozzles of the spray heads 32 located on the lower edge of the spray chamber 31 face downwards. The downward-facing nozzles can spray the vegetation directly below it without being affected by the blower fan 2, thus avoiding the effect of the blower fan 2 blowing the mist far away and missing the vegetation directly below the blower device.

[0064] The support frame 4 is equipped with footboards 41 for climbing, which allows workers to climb onto the fan unit for maintenance, improving work efficiency and avoiding delays in use due to maintenance.

[0065] The bottom of the bracket 4 is equipped with a moving device 9 with a braking function. The water tank 7 is installed on the moving device 9, which can move the device together with the water tank 7 to the required location.

[0066] The support frame 4 is made of a telescopic rod with telescopic function. The height of the support frame 4 ranges from 1 meter to 10 meters, and can be raised to a maximum height of 10 meters.

[0067] The atomized water mist, under pressure, is sprayed upwards towards the vegetation, pushing the air above it downwards. The frost-prevention principle of the machine mainly utilizes the "temperature inversion phenomenon" to raise the ground temperature. When frost occurs, as heat is lost from the ground, an inversion layer forms 6 to 10 meters above the ground. The temperature difference between this layer and the ground temperature can be as high as 4-6 degrees Celsius. The equipment uses a fan to turbulent the airflow, neutralizing the ground temperature to achieve the frost-prevention effect. The fourth-generation hot air anti-frost device is generally installed at a height of 6 to 8 meters, where the temperature is highest. Utilizing the gravity and pressure of the mist, it quickly blows the relatively warm air from the upper atmosphere towards the fruit trees. The relatively warm air creates convection with the cold air at lower altitudes, raising the temperature of the lower atmosphere and increasing the overall vegetation temperature by 2 to 3 degrees Celsius. Compared to traditional methods that only blow air without the pressure and gravity of the mist, this method quickly replaces cold air with relatively warm air, increasing efficiency by 2 to 3 times. Turning on the fourth-generation hot air antifreeze device during the high temperatures of spring can effectively lower the temperature, thus ensuring the fruit set rate in the orchard. During the high temperatures of summer, turning on the fourth-generation hot air antifreeze device increases airflow, which can effectively improve the quality of the orchard's fruit.

[0068] This device can cover 10 to 15 acres of vegetation, with a total power of 8 kilowatts, a total height of 10 meters, and a coverage radius of 50 to 60 meters. It is rotatably connected to the fan unit and support frame 4, and the fan unit is also rotatably connected to the support frame 5. The gap between the fan unit and support frame 4 allows the fan unit to pass through, enabling fully automatic 360-degree unlimited rotation. The rotation angle can also be set to any angle from 0 to 360 degrees according to the actual terrain. It automatically oscillates up and down, for example, from 10 to 30 degrees, to create a wave-like airflow for optimal frost prevention. It can also be set to automatically start and stop at a set temperature.

[0069] Example 2:

[0070] Under the operation of the high-pressure pump 10, the water in the water tank 7 quickly enters the water inlet pipe 6 and then quickly enters the spray head 8 in the atomization chamber 1 for initial atomization.

The nozzles of the spray heads 32 located on the lower edge of the spray chamber 31 face downwards. The downward-facing nozzles can spray the vegetation directly below it without being affected by the blower fan 2, thus avoiding the effect of the blower fan 2 blowing the mist far away and missing the vegetation directly below the blower device.
