[0002] Edible fungi refer to mushrooms (large fungi) with large fruiting bodies and can be eaten. They are generally called mushrooms. Since edible fungi grow in different regions and different ecological environments, and require water at all stages of growth and development, it is necessary to strictly control the humidity of the edible fungi growth environment to ensure their normal growth.

[0003] The Chinese patent disclosed "A humidifier for edible fungus cultivation" with application number 202123210360.9, including a base and a water tank, a water tank is provided at one end above the base, a group of bottom plates are provided at the other end above the base, support rods are provided at both ends above the bottom plates, connecting pipes are provided between the support rods, sliders are provided on both sides of the support rods close to the connecting pipes, and a screw rod is provided through the inside of the slider.

[0004] Although the humidifier can effectively humidify the cultivation environment of edible fungi, its design has certain shortcomings. The device mainly relies on atomizing nozzles for humidification, which can easily cause nozzle damage after long-term use, increasing operating costs. At the same time, the atomized water mist will combine with the floating dust in the air, resulting in uneven humidity distribution, and the presence of floating dust will accelerate the attenuation of humidity, making it difficult for the cultivation environment to remain stable for a long time. Therefore, in practical applications, it is necessary to consider improving the humidification method to improve the humidification effect and reduce costs. Summary of the invention

[0005] The purpose of the present invention is to provide a humidity control device for a solar greenhouse for edible fungi. The present invention solves the problem that the existing devices are unable to collect and process floating dust in the air during humidification, which accelerates the attenuation of humidity and makes it difficult to maintain a stable breeding environment for a long time.

[0006] To achieve the above object, the present invention provides the following technical solution: a humidity control device for a solar greenhouse for edible fungi, comprising a humidity sensor, a piston cylinder, and a sewage pipe, a water inlet pipe and an air pipe respectively connected to the piston cylinder, and further comprising: The first humidity regulating mechanism comprises a cylinder connected to the piston cylinder, and the outer wall of the cylinder is evenly provided with a plurality of second through holes; when the first humidity regulating mechanism regulates the humidity, the air in the breeding environment is transported to the piston cylinder through the air pipe, humidified by the water in the piston cylinder, and then discharged from the second through holes, thereby controlling the humidity of the breeding environment, and at the same time, the floating dust in the air remains in the water in the piston cylinder; The second humidity regulating mechanism comprises a first piston slidably mounted on the inner wall of the piston cylinder and an atomizing nozzle connected to the piston cylinder; when the second humidity regulating mechanism is working, the air pipe is closed, the water in the water inlet pipe enters the piston cylinder, and the water squeezes the first piston. At this time, the water with floating dust is squeezed and discharged from the sewage pipe, and the water in the water inlet pipe is discharged from the atomizing nozzle, so as to control the humidity of the breeding environment; The gravity of the first piston is greater than the buoyancy of water, and the outer wall of the first piston is symmetrically provided with a first through hole, whose water flow rate is less than the flow rate of the water inlet pipe; when the water inlet pipe injects water into the piston cylinder, the water pushes the first piston to move upward in the piston cylinder and closes the sewage pipe; when the water inlet pipe stops inflowing water, the first piston descends in the piston cylinder, and the first through hole allows the water to transfer to the top of the first piston; The opening and closing assembly includes a telescopic rod installed on the upper end surface of the first piston, and a floating ball is installed on the upper end surface of the telescopic rod; when the first piston moves up, the floating ball moves up and the sewage pipe is connected with the piston cylinder; when the first piston moves down, the floating ball moves down and the sewage pipe is disconnected from the piston cylinder to prevent sewage backflow.

[0007] Preferably, the upper end surface of the cylinder is connected with a first pipe, the first pipe is connected with the piston cylinder away from the cylinder, and the diameter of the first pipe is smaller than the thickness of the first piston, and a filter is installed at the connection between the first pipe and the piston cylinder.

[0008] Preferably, the outer wall of the sewage pipe is connected to a third pipe, a support plate is installed at one end of the third pipe away from the sewage pipe, a fifth pipe is installed at the center of the support plate, and the lower end surface of the fifth pipe is connected to the piston cylinder.

[0009] Preferably, a lifting ring is symmetrically installed on the upper end surface of the support plate.

[0010] Preferably, a limit rod is installed on the inner wall of the fifth pipe.

[0011] Preferably, the outer wall of the trachea is connected to a fourth pipeline, and a one-way valve is installed on the inner wall of the fourth pipeline.

[0012] Preferably, the upper end surface of the atomizing nozzle is connected with a second pipe, the second pipe is connected with the piston cylinder at a side away from the atomizing nozzle, and the diameter of the second pipe is smaller than the thickness of the first piston.

[0013] Preferably, a spring is installed on the inner wall of the cylinder, a second piston is installed on the upper end surface of the spring, and the second piston is flush with the second through hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention is provided with a first humidifying mechanism. When the humidity value is slightly different from the preset value, the vacuum pump works, the one-way valve in the fourth pipe is opened, the gas enters the piston cylinder from the fourth pipe, and then the humidified gas is discharged from the first pipe. The filter screen will leave the floating dust in the air inside the piston cylinder. At this time, the gas discharged from the first pipe will squeeze the second piston, the second piston no longer blocks the second through hole, and the spring is compressed by the second piston. When the humidity is controlled at a preset value, the water pump stops working. At this time, the floating dust will be inside the piston cylinder, and the collection is completed, so as to reduce the dust in the breeding environment, thereby reducing the attenuation rate of the humidity. The present invention is provided with a second humidifying mechanism. When the first humidifying mechanism cannot effectively increase the humidity, the water pump starts to work, and the water in the water inlet pipe flows into the piston cylinder. At this time, the water pressure will first lift the first piston, and because the water flow rate of the water inlet pipe is greater than the water flow rate of the first through hole on the first piston, the first piston will continue to rise in the piston cylinder. At the same time, the water in the first through hole will flow upward to flush the inner wall of the piston cylinder. At this time, the water containing floating dust in the piston cylinder will flow from the third pipe to the sewage pipe for discharge, completing the dust treatment; The present invention is provided with an opening and closing component. When the water pump stops working, the pressure in the piston cylinder decreases, the first piston descends in the piston cylinder, and the first piston drives the floating ball to descend through the telescopic rod. The floating ball will block the fifth pipe to prevent the water containing floating dust from flowing back. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the water with floating dust is squeezed and discharged from the sewage pipe 1, and the water in the water inlet pipe 6 is discharged from the atomizing nozzle 8, so as to control the humidity of the breeding environment; The gravity of the first piston 15 is greater than the buoyancy of water, and the outer wall of the first piston 15 is symmetrically provided with a first through hole 17, whose water flow rate is less than the flow rate of the water inlet pipe 6; when the water inlet pipe 6 injects water into the piston cylinder 12, the water pushes the first piston 15 to move upward in the piston cylinder 12, closing the sewage pipe 1; when the water inlet pipe 6 stops inflowing water, the first piston 15 descends in the piston cylinder 12, and the first through hole 17 allows the water to transfer to the top of the first piston 15; The opening and closing assembly includes a telescopic rod 14 installed on the upper end surface of the first piston 15, and a floating ball 13 is installed on the upper end surface of the telescopic rod 14; when the first piston 15 moves up, the floating ball 13 moves up, and the sewage pipe 1 is connected with the piston cylinder 12; when the first piston 15 moves down, the floating ball 13 moves down, and the sewage pipe 1 is disconnected from the piston cylinder 12 to prevent sewage backflow; The piston cylinder 12 can be provided in multiple numbers to increase the ability to control humidity, and the humidity sensor is provided at a level position with the edible fungi to make the humidity more accurate; Further, such as Figure 1 and Figure 2 As shown, the upper end surface of the cylinder 5 is connected with a first pipe 4, the first pipe 4 is connected with the piston cylinder 12 at a side away from the cylinder 5, and the diameter of the first pipe 4 is smaller than the thickness of the first piston 15, and a filter screen (not shown in the figure) is installed at the connection between the first pipe 4 and the piston cylinder 12; When the first piston 15 abuts against the top wall of the piston cylinder 12, the first piston 15 blocks the first pipe 4; The filter can prevent impurities from being discharged from the first pipe 4; Further, such as Figure 1 , Figure 2 and Figure 3As shown, the outer wall of the sewage pipe 1 is connected to a third pipe 9, a support plate 3 is installed at one end of the third pipe 9 away from the sewage pipe 1, a fifth pipe 16 is installed at the center of the support plate 3, and the lower end surface of the fifth pipe 16 is connected to the piston cylinder 12; Further, such as Figure 1 As shown, a lifting ring 2 is symmetrically mounted on the upper end surface of the support plate 3; The piston cylinder 12 can be installed on the top of the greenhouse through the lifting ring 2; Further, such as Figure 3 As shown, a limit rod 1301 is installed on the inner wall of the fifth pipe 16; The limiting rod 1301 can block the floating ball 13. When the first piston 15 descends, the floating ball 13 can be quickly driven down through the telescopic rod 14 to close the fifth pipe 16 to prevent water from flowing back. Further, as shown in the figure, the outer wall of the air pipe 11 is connected to the fourth pipe 10, and the inner wall of the fourth pipe 10 is installed with a one-way valve (not shown in the figure); The one-way valve can prevent the water in the piston cylinder 12 from flowing to the fourth pipe 10; Further, such as Figure 1 and Figure 2 As shown, the upper end surface of the atomizing nozzle 8 is connected with a second pipe 7, the second pipe 7 is connected with the piston cylinder 12 at a side away from the atomizing nozzle 8, and the diameter of the second pipe 7 is smaller than the thickness of the first piston 15; When the first piston 15 abuts against the bottom wall of the piston cylinder 12, the first piston 15 blocks the second pipe 7; Further, such as Figure 4 As shown, a spring 19 is installed on the inner wall of the cylinder 5, and a second piston 20 is installed on the upper end surface of the spring 19, and the second piston 20 is flush with the second through hole 18; When the first piston 15 moves upward in the piston cylinder 12, the spring 19 supports the second piston 20 to prevent water from flowing into the cylinder 5; Further, such as Figure 2 and Figure 3 As shown, a magnet (1501) is installed on the lower end surface of the first piston 15, and an iron block 1201 is installed inside the lower end surface of the piston cylinder 12; The magnet 1501 at the bottom of the first piston 15 attracts the iron block 1201 in the piston cylinder 12 , which can further increase the blocking force of the floating ball 13 on the fifth pipe 16 and prevent the gas from leaking from the fifth pipe 16 .

[0018] Working principle: Step 1: Connect the water pump through the water inlet pipe 6, the air pipe 11 to the air pump, and the sewage pipe 1 to the sewer. When the humidity sensor detects that the humidity is reduced, if the humidity is smaller than the predetermined difference, the air pump works, the one-way valve in the fourth pipe 10 opens, and the gas enters the piston cylinder 12 from the fourth pipe 10, and then the humidified gas is discharged from the first pipe 4. The filter will leave the floating dust in the air inside the piston cylinder 12. At this time, the gas discharged from the first pipe 4 will squeeze the second piston 20, and the second piston 20 will no longer block the second through hole 18. The spring 19 is compressed by the second piston 20. When the humidity is controlled at a predetermined value, the water pump stops working. At this time, the floating dust will exist inside the piston cylinder 12 and complete the collection, and the spring 19 will extend to lift the second piston 20 again. When the gas enters the piston cylinder 12, the magnet 1501 under the first piston 15 is attracted to the iron block 1201 at the bottom of the piston cylinder 12. Since the thickness of the first piston 15 is greater than the diameter of the second pipe 7, the second pipe 7 does not leak gas and water. At the same time, the first piston 15 pulls the floating ball 13 through the telescopic rod 14 to block the fifth pipe 16 to prevent gas leakage. Step 2: When the gas humidification cannot effectively increase the humidity, the air pump stops working, the one-way valve is closed, the water in the piston cylinder 12 will not enter the fourth pipe 10, and the water pump starts working at the same time, the water in the water inlet pipe 6 will flow into the piston cylinder 12, and the water pressure will first lift the first piston 15, and because the water flow of the water inlet pipe 6 is greater than the water flow of the first through hole 17 on the first piston 15, the first piston 15 will continue to rise, and the first piston 15 drives the floating ball 13 to rise through the telescopic rod 14. At this time, the floating ball 13 no longer closes the fifth pipe 16. Since the spring 19 supports the second piston 20 at this time, the water will not flow into the cylinder 5, so the water containing floating dust in the piston cylinder 12 will flow from the third pipe 9 to the sewage pipe 1 for discharge; At this time, since the water in the first through hole 17 will flow upward, it will flush the inner wall of the piston cylinder 12 to clean it; When the floating ball 13 is blocked by the limiting rod 1301, the telescopic rod 14 begins to shrink until the first piston 15 contacts the top wall of the piston cylinder 12, and the first piston 15 closes the fifth pipe 16. At this time, since the thickness of the first piston 15 is greater than the diameter of the first pipe 4, the first piston 15 blocks the first pipe 4 to prevent water from entering the first pipe 4, so the water passes through the second pipe 7 and is sprayed from the atomizing nozzle 8 to perform humidification work; Step 3: When the aquaculture environment is humidified to a predetermined value by the atomizing nozzle 8, the water pump stops working. At this time, the pressure in the piston cylinder 12 decreases, and the first piston 15 descends in the piston cylinder 12. The first piston 15 drives the floating ball 13 to descend through the telescopic rod 14. The floating ball 13 will block the fifth pipe 16 to prevent water from flowing back, and the first piston 15 will directly fall to the bottom of the piston cylinder 12. Since the thickness of the first piston 15 is greater than the diameter of the first pipe 4, the water level in the piston cylinder 12 will be lower than the first pipe 4 at this time, and water will not flow to the first pipe 4 when the gas is humidified.
