[0037] Reference Figure 1 As shown, the roxburghii planting greenhouse of the utility model is made into the following embodiments:

[0038] The anoectochilus roxburghii planting greenhouse comprises a greenhouse body 100, a ventilation channel 200, a water curtain assembly 300, a fan 400, a heat pump assembly 500, a temperature sensor 600, and a controller.

[0039] The shed 100 is provided with an air inlet 110 and an air outlet 120 . External air enters the shed 100 from the air inlet 110 , and the air inside the shed 100 flows out to the outside from the air outlet 120 , which helps to form a ventilation environment required by the golden thread vine inside the shed 100 .

[0040] The ventilation duct 200 has an air inlet end 210 and an air outlet end 220. The air inlet end 210 is connected to the outside, and the air outlet end 220 is connected to the air inlet 110. A fan 400 is arranged inside the ventilation duct 200. After the fan 400 is started, the air in the ventilation duct 200 is blown from the air inlet end 210 to the air outlet end 220, so that the outside air can flow into the shed 100 through the ventilation duct 200.

[0041] The water curtain assembly 300 is disposed in the ventilation passage 200 .

[0042] The water curtain assembly 300 generally includes a water supply pipe, a water curtain paper component, a drainage pipe, a filter pool, and a pipeline pump. The pipeline pump connects the filter pool and the water supply pipe. The port of the water supply pipe is arranged above the water curtain paper component. The drainage pipe connects the bottom of the water curtain paper component and the filter pool. The pipeline pump draws the water filtered from the filter pool to the top of the water curtain paper component, and then the water flows along the water curtain paper component and flows back to the filter pool through the drainage pipe.

[0043] The water curtain paper component is usually made of a special paper honeycomb structure material. When water is evenly distributed on its surface and forms a water film, if the fast-flowing air passes through the water curtain paper component, the water in the water film will absorb the heat in the air and evaporate, thereby taking away a large amount of heat energy, so that the temperature of the air passing through the water curtain paper component in the ventilation channel 200 is reduced, achieving a cooling effect. Specifically, when water molecules evaporate, they take away the heat in the air, which not only reduces the air temperature, but also increases the air humidity.

[0044] The heat pump assembly 500 includes a heat exchanger 510, an expansion valve 520, an evaporator 530, and a compressor 540 that are connected in sequence. The refrigerant circulates among the heat exchanger 510, the expansion valve 520, the evaporator 530, and the compressor 540, and the refrigerant releases heat in the heat exchanger 510 and absorbs heat in the evaporator 530.

[0045] The heat exchanger 510 is disposed in the ventilation passage 200 , and the evaporator 530 is disposed at the air outlet 120 .

[0046] External air flows through the ventilation passage 200 , and the external air is heated by the heat exchanger 510 and humidified and cooled by the water curtain assembly 300 .

[0047] The temperature sensor 600 is disposed in a region between the water curtain assembly 300 and the air outlet 220 , and the temperature sensor 600 measures the temperature of the air heated by the heat exchanger 510 and cooled by the water curtain assembly 300 .

[0048] The air inside the shed body 100 is discharged through the air outlet 120 and flows through the evaporator 530. The temperature inside the shed body is generally higher than the outside temperature. The air temperature inside the shed body 100 is higher than the outside air. The heat dissipated by the air discharged to the outside is absorbed by the evaporator 530, thereby improving the heat absorption efficiency of the evaporator 530.

[0049] The controller is preset with a first preset temperature and a second preset temperature. In this embodiment, the first preset temperature is 20°C and the second preset temperature is 25°C.

[0050] The controller is electrically connected to the water curtain assembly 300 , the fan 400 , the heat pump assembly 500 , and the temperature sensor 600 .

[0051] The temperature sensor 600 measures the temperature of the air about to enter the shed 100 , and sends the measured temperature to the controller. The controller compares the measured temperature with a first preset temperature. If the measured temperature is lower than the first preset temperature, the controller turns on the heat pump assembly 500 .

[0052] If the measured temperature is higher than the first preset temperature, the controller compares the measured temperature with the second preset temperature, and if the measured temperature is lower than the second preset temperature, the controller can maintain the state of the heat pump assembly 500. For example, if the measured temperature is lower than the first preset temperature, the heat pump assembly 500 is turned on and the temperature of the air entering the shed 100 is increased until it is higher than the first preset temperature, and the heat pump assembly 500 is kept turned on.

[0053] The measured temperature of the air after being heated by the heat pump assembly 500 is higher than the second preset temperature, indicating that the temperature of the air entering the shed body 100 is too high, so the controller is required to shut down the heat pump assembly 500.

[0054] When the heat pump assembly 500 is in the closed state, if the measured temperature is higher than the first preset temperature, it proves that the air cooled by the water curtain assembly 300 meets the growth requirements of the golden thread vine, and the heat exchanger 500 does not need to be heated, and the heat pump assembly 500 remains in the closed state. If the temperature of the air not heated by the heat pump assembly 500 is higher than the second preset temperature, it proves that the outside temperature is too high, so it is necessary to increase the cooling power of the water curtain assembly 300, such as reducing the water temperature of the water curtain assembly 300, increasing the water flow rate of the water curtain assembly 300, and speeding up the fan 400.

[0055] In some embodiments, the shed 100 extends from front to back, the length of the shed 100 in the front-to-back direction is greater than the length of the shed 100 in the left-to-right direction, the air inlet 110 is arranged on the front side wall of the shed 100, and the air outlet 120 is arranged on the rear side wall of the shed 100.

[0056] The air entering the shed body 100 flows from front to back throughout the shed body 100 , so that the humid air forms a uniform humid environment inside the shed body 100 , and makes the temperature inside the entire shed body 100 more uniform.

[0057] In some embodiments, the interior of the shed 100 is divided into a plurality of planting units 101 in sequence along the front-to-back direction, and an air inlet 102 is provided on the left side wall or the right side wall of each planting unit 101, the air inlet 102 is connected to the air outlet end 220 of the ventilation channel 200, an air inlet door 1021 is provided on the air inlet 102, and a humidity sensor 104 is provided on each planting unit 101.

[0058] The air intake valve 1021 is an electronically controlled valve, and the controller is electrically connected to the air intake valve 1021 and the humidity sensor 104 .

[0059] The controller is preset with a preset value of humidity, which is 80% in the present embodiment. When the humidity measured by any one or more humidity sensors 104 is lower than the preset value, the controller finds the corresponding planting unit 101 according to the humidity sensor 104, and opens the air inlet door 1021 of the planting unit 101, so that part of the humid air in the ventilation channel 200 can enter the corresponding planting unit 101 through the air inlet door 1021, thereby increasing the humidity of the planting unit 101 in a more targeted manner. Although the humid air entering the planting unit 101 will diffuse outward, it can increase the humidity of the planting unit 101 whose humidity is lower than the preset value in a short period of time, and the shed body 100 is still continuously supplied with humid air flowing through the entire shed body 100, thereby making the humidity of multiple planting units 101 more uniform.

[0060] After the humidity of the planting unit 101 increases and reaches a preset value, the controller closes the air intake valve 1021 .

[0061] In some embodiments, an air inlet 102 is disposed on the right side wall of each planting unit 101 , an air outlet 103 is disposed on the left side wall of each planting unit 101 , and an air outlet door 1031 is disposed on the air outlet 103 .

[0062] The air outlet valve 1031 is an electrically controlled valve, and the controller is electrically connected to the air outlet valve 1031 .

[0063] The controller is preset with a preset value of humidity, which is 80% in this embodiment. When the humidity measured by any one or more humidity sensors 104 is lower than the preset value, the controller finds the corresponding planting unit 101 according to the humidity sensor 104, and opens the air inlet door 1021 and the air outlet door 1031 of the planting unit 101, so that part of the humid air in the ventilation channel 200 can enter the corresponding planting unit 101 through the air inlet door 1021 and flow out from the air outlet door 1031, so that the humid air flows through the planting unit 101 in the left-right direction, and the humid air flowing through the entire shed 100 in the front-back direction inside the shed 100 also partially flows out from the air outlet 103 of the planting unit 101, so as to increase the humidity of the planting unit 101 more specifically, and thus make the humidity of multiple planting units 101 more uniform. When the humidity of the planting unit 101 is quickly increased to the preset value in a short period of time, the controller closes the air inlet door 1021 and the air outlet door 1031 corresponding to the planting unit 101.

[0064] In some embodiments, the air outlet 120 is provided with an air outlet pipe 121 , the evaporator 530 is disposed in the air outlet pipe 121 , and the air outlets 103 of the plurality of planting units 101 are connected to the air outlet pipe 121 .

[0065] When the air outlet 103 of any one or more planting units 101 is opened, the humid air passing through the corresponding planting unit 101 flows into the air outlet pipe 121 from the air outlet 103 , so that the evaporator 530 absorbs the heat of the humid air discharged from the air outlet 103 of the planting unit 101 .

[0066] In some embodiments, the air outlet pipe 121 extends to the right side of the shed body 100 , and the ventilation passage 200 extends to the right side of the shed body 100 .

[0067] Since the heat pump assembly 500 needs to use a refrigerant pipeline to sequentially connect the heat exchanger 510, the expansion valve 520, the evaporator 530, and the compressor 540, the air outlet pipe 121 and the ventilation channel 200 are arranged on the same side of the shed body 100, which helps to reduce the distance between the heat exchanger 510 and the evaporator 530, thereby helping to shorten the length of the refrigerant pipeline of the heat pump assembly 500 and reduce the heat loss caused by the refrigerant flowing in the refrigerant pipeline.

[0068] In some embodiments, each air outlet 103 is provided with an exhaust fan 700 , and the air outlet duct 121 is provided with an exhaust fan 700 .

[0069] When the air inlet valve 1021 and the air outlet valve 1031 of the planting unit 101 are opened, the controller turns on the exhaust fan 700 corresponding to the planting unit 101, and increases the exhaust efficiency of the air outlet 103 through the exhaust fan 700, thereby reducing the amount of humid air flowing left and right that is diverted by the humid air flowing front and back in the greenhouse 100, thereby helping the humid air flowing along the left and right directions of the planting unit 101 to flow through the entire planting unit 101.

[0070] The exhaust fan 700 provided in the air outlet duct 121 helps to guide the moist air inside the shed body 100 to flow through the entire shed body 100 in the front-to-back direction.

[0071] In some embodiments, humidity sensor 104 is disposed in the middle of growing unit 101 .

[0072] After the air inlet valve 1021 is opened, the humidity near the air inlet 102 is much greater than the rest of the planting unit 101, and the humidity on the side farthest from the air inlet 102 is much lower than the rest of the planting unit 101. Avoid setting the humidity sensor 104 near the air inlet 102 or on the side farthest from the air inlet 102, and ensure that the humidity sensor 104 measures a relatively uniform position of the planting unit 101, which helps the humidity sensor 104 to accurately measure the humidity of the planting unit 101.

[0073] In some embodiments, the heat exchanger 510 is disposed in a region between the air inlet end 210 and the water curtain assembly 300 .

[0074] The external air is first heated by the heat exchanger 510 , and the ability of the heated air to hold moisture is improved. The heated air is then humidified and cooled by the water curtain assembly 300 , which helps to increase the humidity of the humid air and improve the humidification effect on the internal environment of the shed 100 .

[0075] In some embodiments, the golden thread vine cultivation greenhouse also includes a water receiving tray 531, a water supply pipe 532, and a water pump 533. The water receiving tray 531 is arranged below the evaporator 530, the water supply pipe 532 connects the water receiving tray 531 and the filtered water pool of the water curtain assembly 300, and the water pump 533 is arranged in the water supply pipe 532.

[0076] The water condensed by the evaporator 530 drops into the water receiving tray 531, and the condensed water collected by the water receiving tray 531 is returned to the filter water pool of the water curtain assembly 300 through the water pump 533. The water curtain assembly 300 recycles the water condensed by the evaporator 530 to reduce the waste of water resources.

[0077] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
