The main function of the heating device is to maintain the temperature inside the sunlight greenhouse, create a suitable growth environment for crops, and ensure that crops can still grow normally in the cold season by intelligently adjusting the temperature and humidity in the greenhouse, thereby improving the efficiency and yield of greenhouse cultivation.

[0003] The patent with the publication number CN222366742U discloses a new type of energy-saving and environment-friendly intelligent heating device for a sunlight greenhouse, including a wall body. A temperature sensor is fixedly connected to the bottom end face of the wall body, and a heating mechanism is arranged on the inner bottom of the wall body. For this new type of energy-saving and environment-friendly intelligent heating device for a sunlight greenhouse, when the motor starts, it drives the rotating shaft and the worm to rotate, and then drives the inclined pipe to rotate, realizing the rotation of the spray head, thereby expanding the coverage range that the spray holes can cover. Part of the hot steam passes through the spiral spray pipe, causing the spray head to rotate, realizing the self-rotation of the spray head, further expanding the spraying range of the hot steam, improving the uniformity of the distribution of heat energy in different areas of the greenhouse, and providing a suitable temperature environment for the growth of crops. The first seal ring and the second seal ring improve the sealing degree between the steam pipe and the inclined pipe, and between the inclined pipe and the spray head, avoiding water leakage at the connection part.

A vertical frame 15 is fixed to the bottom surface of the electric fan 16. The bottom surface of the vertical frame 15 is fixedly connected to the bottom end inside the housing 3. The vertical frame 15 is used to support the electric fan 16. The water inlet pipe 6 and the feed pipe 7 are located above the circular rod 10. A connecting piece is respectively fixed to the right sides of the water inlet pipe 6 and the feed pipe 7. A plurality of heat dissipation openings are opened on the outer wall of the circular shell 8. The graphene electric heater 1 is located behind the electric fan 16. The electric control spray head 5 is located below the back surface of the air outlet of the square shell 13. The circular rod 10 rotates forward in the housing 3. The circular rod 10 drives the disc 11 to rotate forward. The disc 11 drives the U-shaped strip plate 12 to rotate forward. The U-shaped strip plate 12 stirs the water and nutrient solution in the housing 3, making the water and nutrient solution mix evenly. The graphene electric heater 1 transfers heat to the housing 3. The housing 3 transfers heat to the water and nutrient solution, increasing the heat of the water and nutrient solution and reducing the waste of heat energy of this device. The evenly mixed water and nutrient solution enter the L-shaped pipe 4. The electric control spray head 5 on the L-shaped pipe 4 sprays the water mist mixed with water and nutrient solution. The hot air blown out from the air outlet of the square shell 13 blows the water mist to a farther place, preventing the intelligent heating device for the sunlight greenhouse from having a poor wetting effect on the plant surface due to uneven mixing of water and nutrient solution when heating; The outer wall of the round rod 10 is provided with a scraper 17 for scraping off the nutrient solution residue attached to the inner wall of the shell 3 . The outer wall of the scraper 17 is provided with an anti-foam device 18 for skimming off the foam of the mixed liquid in the shell 3 .

[0024] Since it is difficult to mix water and nutrient solution evenly, it is easy to cause uneven fertilizer content for plants. When using this device, the square shell 13 supports the vertical frame 15, and the operator starts the electric fan 16 on the vertical frame 15 through the remote control. The blades on the electric fan 16 start to rotate. At this time, the gas in the sunlight greenhouse enters from the round mouth, and the round cover 14 on the square shell 13 prevents foreign matter from entering the square shell 13. The temperature sensor 2 senses the real-time temperature of the sunlight greenhouse. The temperature sensor 2 has a built-in sound alarm. When the temperature in the sunlight greenhouse is low, the temperature sensor 2 sends an alarm signal through the sound alarm, and the operator starts the graphene electric heater 1 through the remote control. , the graphene electric heater 1 converts electrical energy into heat and dissipates it due to its excellent thermal conductivity. At the same time, the blades on the electric fan 16 blow air to the front of the graphene electric heater 1, and the airflow heated by the graphene electric heater 1 is discharged from the air outlet of the square shell 13. The shell 3 is mounted under the graphene electric heater 1, and the water body is input through the water inlet pipe 6 on the shell 3, and the nutrient solution is input through the feed pipe 7 on the shell 3.

The disk 11 drives the U-shaped strip 12 to rotate forward, and the U-shaped strip 12 stirs the water and nutrient solution in the shell 3 to make the water and nutrient solution evenly mixed. The graphene electric heater 1 transfers heat to the shell 3, and the shell 3 transfers heat to the water and nutrient solution, thereby increasing the heat of the water and nutrient solution and reducing the heat energy waste of the device. The evenly mixed water and nutrient solution enter the L-shaped tube 4, and the electric-controlled spray head 5 drives the armature through the electromagnet to act on the piston rod to perform high-speed reciprocating motion, thereby forming an air suction phenomenon, thereby sucking the liquid out of the container. This movement generates high pressure, which is sprayed out at high speed and atomized by the nozzle, and the electric-controlled spray head 5 on the L-shaped tube 4 sprays the water and nutrient solution mixed. The water mist is blown away by the air outlet of the square shell 13. When the solar greenhouse is heated up in winter, the water in the solar greenhouse evaporates quickly. The environment in the solar greenhouse is not humid enough, and the water on the surface of the plants is lost. The solar greenhouse intelligent heating device can release water containing nutrient solution when heating, so that the surface of the plants can be kept moist while the nutrient solution can be applied, thereby allowing the plants to grow more beneficially, preventing the water body and the nutrient solution from being mixed unevenly when the device is in use, thereby avoiding the problem of poor effect of wetting the surface of the plants due to uneven mixing of the water body and the nutrient solution when the solar greenhouse intelligent heating device is heating.

The return-shaped frame 183 drives the filter screen 184 to rotate forward. During the rotation of the filter screen 184, the filter screen 184 skims the foam above the water body and the nutrient solution, avoiding the poor spraying effect of the device caused by the accumulation of a large amount of foam in the housing 3 when the intelligent heating device for the solar greenhouse releases heat.

[0028] A concave block 185 is fixed to the inner wall of the notch of the return-shaped frame 183. A short rod 186 is fixed to one side of the concave block 185 close to the chamfering plate 175.
