Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Please refer to Figure 1-3 , a temperature and light control structure for a greenhouse for growing watermelons and melons in summer, comprising a top plate 1, a working mechanism for temperature control is installed at the bottom of the top plate 1, a fan mechanism for accelerating airflow is installed on one side of the working mechanism, and a lighting mechanism for providing light for the greenhouse is installed at the bottom of the working mechanism;

[0025] The working mechanism includes a working frame 2, one side of the working frame 2 is fixedly connected to a pump body 3, one side of the pump body 3 is fixedly connected to a connecting pipe 4, the front of the working frame 2 is provided with a through hole 5 and the through hole 5 is semicircular, the front of the working frame 2 is rotatably connected to a first rotating shaft 6, the front of the first rotating shaft 6 is fixedly connected to a knob, the back of the first rotating shaft 6 is fixedly connected to a disc 7, the inner cavity of the disc 7 is provided with a vent hole 8 and the vent hole 8 is located on the left side of the inner cavity of the disc 7.

[0026] The inner cavity of the top plate 1 is provided with a limiting hole 9, and the inner cavity of the limiting hole 9 is installed with a limiting member 10. The limiting holes 9 and the limiting members 10 are both distributed in a matrix array.

[0027] An observation hole 11 is provided on the back of the working frame 2 , and a rotating plate 12 is rotatably connected to the inner cavity of the observation hole 11 .

[0028] In the embodiment of the utility model, the top plate 1 is fixed at a specified position, and the fixing of the device body is completed by the cooperation of the stopper 10 and the stopper hole 9, and then the connecting pipe 4 on one side of the pump body 3 is connected to the external environment. When it is necessary to accelerate the exchange of gas inside and outside the greenhouse, the pump body 3 is started at this time, and the pump body 3 pumps the external gas into the inner cavity of the working frame 2 through the connecting pipe 4, and then passes it into the interior of the greenhouse through the vent 8 and the through hole 5 in turn. When it is necessary to adjust the flow rate of the gas, the knob is turned at this time to drive the first rotating shaft 6 and the disc 7 to rotate. Since the vents 8 are concentrated in the semicircle of the disc 7, when the disc 7 rotates, the number of vents 8 for gas circulation is reduced, and a part of the vents 8 are covered by the front of the working frame 2, thereby adjusting the flow rate of the gas. This operation method is simple and efficient, and also avoids the problems caused by frequent adjustment of the pump body 3.

[0029] Please refer to Figure 1-4 The fan mechanism includes a fan frame 13, a fixing seat 14 is fixedly connected to the inner cavity of the fan frame 13, a second rotating shaft 15 is rotatably connected to the inner cavity of the fixing seat 14, a heat dissipation fan 16 is fixedly connected to the outer ring of the second rotating shaft 15, and a second bevel gear 17 is fixedly connected to one side of the second rotating shaft 15 located in the inner cavity of the fan frame 13.

[0030] A third motor 18 is installed in the inner cavity of the fan frame 13 . A third rotating shaft 19 is fixedly connected to one side of the output shaft of the third motor 18 .

[0031] The lighting mechanism includes a base plate 21, the inner cavity of the base plate 21 is provided with a threaded hole, the inner cavity of the threaded hole is threadedly connected to a threaded rod 22, the top of the threaded rod 22 is fixedly connected to a crank, the bottom of the threaded rod 22 is rotatably connected to a lifting plate 23, and the bottom of the lifting plate 23 is installed with a lighting lamp 24.

[0032] A switch 25 is installed on the front of the lifting plate 23 , and telescopic rods 26 are fixedly connected between the lifting plate 23 and the bottom plate 21 , and the telescopic rods 26 are distributed in a matrix array.

[0033] In the embodiment of the utility model, the switch 25 is started to turn on the lighting lamp 24 to achieve the lighting effect inside the greenhouse. The crank is turned to drive the threaded rod 22 to rotate in the threaded hole, thereby driving the lifting plate 23 connected to the bearing to rise and fall. A telescopic rod 26 is fixedly connected between the lifting plate 23 and the bottom plate 21, thereby limiting the movement direction of the lifting plate 23 and improving the stability of the lifting plate 23. The lifting and lowering of the lifting plate 23 will change the height of the lighting lamp 24 and change the light intensity of the watermelon.

[0034] When in use, first fix the top plate 1 in the specified position, and fix the device body by the cooperation of the limiter 10 and the limit hole 9, and then connect the connecting pipe 4 on one side of the pump body 3 to the external environment. When it is necessary to accelerate the exchange of gas inside and outside the greenhouse, start the pump body 3 at this time, and the pump body 3 pumps the external gas into the inner cavity of the working frame 2 through the connecting pipe 4, and then passes it into the interior of the greenhouse through the vent 8 and the through hole 5 in turn. When it is necessary to adjust the flow rate of the gas, turn the knob at this time to drive the first rotating shaft 6 and the disc 7 to rotate. Since the vents 8 are concentrated in the semicircle of the disc 7, when the disc 7 rotates, the number of vents 8 for gas circulation is reduced, and a part of the vents 8 are covered by the front of the working frame 2, thereby adjusting the flow rate of the gas. This operation method is simple and efficient, and it also avoids the problems caused by frequent adjustment of the pump body 3.

[0035] The third motor 18 is started to drive the third rotating shaft 19 and the third bevel gear 20 to rotate. Since the third bevel gear 20 is meshed with the second bevel gear 17, the second bevel gear 17 and the second rotating shaft 15 are driven to rotate. During the rotation of the second rotating shaft 15, the cooling fan 16 is driven to rotate, accelerating the flow of the surrounding air, thereby accelerating the temperature adjustment effect.

[0036] The switch 25 is turned on to turn on the lighting lamp 24, thereby achieving the lighting effect inside the greenhouse. The crank is turned to drive the threaded rod 22 to rotate in the threaded hole, thereby driving the lifting plate 23 connected to the bearing to rise and fall. A telescopic rod 26 is fixedly connected between the lifting plate 23 and the bottom plate 21, thereby limiting the movement direction of the lifting plate 23 and improving the stability of the lifting plate 23. The lifting and lowering of the lifting plate 23 will change the height of the lighting lamp 24 and change the light intensity of the watermelon.
