[0033] like Figures 1-8 As shown, this embodiment of the invention provides a distributed microporous spray humidification device for a shelf-type mushroom house, including a main frame 1, a water tank 2, and multiple spray units; In one embodiment, an upper frame rod 10 and multiple horizontally arranged aeroponic racks 11 are sequentially fixed on the main frame 1 from top to bottom; a main water pipe 20 is connected to the water tank 2; a spraying unit is installed below the upper frame rod 10 and the aeroponic racks 11; the spraying unit includes branch air pipes 24, branch water pipes 22, a main air pipe 23, and a spraying mechanism 3; the branch water pipes 22 are connected to the main water pipe 20 through a three-way connector 21, the branch air pipes 24 are connected to the main air pipe 23 through a three-way connector 21, and the main air pipe 23 is connected to an external air source and is equipped with a controlled solenoid valve; the spraying... Mechanism 3 includes a mixing tank 32, a main cylinder 30, and multiple atomizing nozzles 37. The mixing tank 32 has an axially narrowed mixing throat 322 inside, and its top is provided with an air pipe connector 321 connected to the branch air pipe 24. Its side wall is provided with a water pipe connector 320 connected to the branch water pipe 22, and the outlet of the water pipe connector 320 leads to the throat area of ​​the mixing throat 322. The main cylinder 30 is connected to the outlet of the mixing tank 32 through a connecting pipe 31. Multiple liquid inlet branch pipes 33 are evenly connected to the upper circumference of the main cylinder 30, and the end of the liquid inlet branch pipe 33 is equipped with an atomizing nozzle 37.

[0034] In this implementation, a distributed humidification network is arranged so that each spraying unit independently serves the cultivation area above it. During operation, water enters the mixing tank 32 through the main water pipe 20 and the branch water pipe 22, while compressed air enters through the main air pipe 23 and the branch air pipe 24. At the throat of the mixing throat 322, the high-speed airflow shears and breaks up the water flow, completing atomization, ensuring the uniformity of humidification and solving the problem of uneven humidity in the upper and lower parts of the tiered mushroom house.

[0035] In one embodiment, the bottom of the mixing tank 32 is fixedly connected with a cylinder body 38, a piston 380 is slidingly connected in the cylinder body 38, a sealing ring 383 is arranged on the piston 380, a regulating screw rod 381 is rotatably connected to one side of the cylinder body 38 through a bearing, the regulating screw rod 381 is threadedly connected to the cylinder body 38, and a hand wheel 384 is fixedly connected to one end of the regulating screw rod 381 and extends to the outside of the cylinder body 38; the piston 380 drives a shearing ring 39 located inside the mixing tank 32 and opposite to the outlet of the mixing throat 322 through a connecting rod 382; guide plates 385 are symmetrically arranged on the connecting rod 382, and guide grooves 386 are formed in the inner wall of the cylinder body 38 and are matched with the shapes of the guide plates 385, and the guide plates 385 are slidingly embedded in the guide grooves 386.

[0036] In this embodiment, the hand wheel 384 drives the regulating screw rod 381 to rotate, the piston 380 is pushed to move in the cylinder body 38, and the shearing ring 39 is driven by the connecting rod 382 to move close to or away from the outlet of the mixing throat 322. By changing the gap between the inner wall of the mixing tank 32 and the gap part 323 formed by the shearing ring 39, the flow rate and the turbulence degree of the gas-liquid mixture can be adjusted, so as to control the fineness of the atomized particles. The cooperation of the guide plates 385 and the guide grooves 386 ensures the stability and linearity of the movement of the connecting rod 382, and prevents deflection.

[0037] In one embodiment, an S-shaped partition plate 34 is fixedly arranged in the main cylinder body 30 to make the fluid inside the main cylinder body 30 flow along an S-shaped path, the bottom of the main cylinder body 30 is configured as a conical hopper, a drain plug cover 36 is detachably and sealingly installed at the bottom end of the conical hopper through threads, and an activated carbon filter core 35 is filled in the conical hopper above the drain plug cover 36.

[0038] In this embodiment, the S-shaped partition plate 34 makes the gas-liquid mixture flow along an S-shaped path in the main cylinder body 30, and the inertial effect can make the large water droplets after atomization collide with the partition plate and gather and fall, the conical hopper structure is convenient for collecting these water droplets and impurities, the activated carbon filter core 35 can effectively adsorb the small impurities carried in the water body and airflow, and the two cooperate to jointly purify the atomized water quality entering the atomizing nozzle 37, prevent the micro-pore from being blocked, the drain plug cover 36 is convenient for regularly cleaning the collected substances and replacing the activated carbon filter core 35, and maintenance is convenient.

[0039] In one embodiment, a tapered necking part 330 is formed in the inner hole at the connection between the liquid inlet branch pipe 33 and the atomizing nozzle 37. An atomizing plate 370 is press-fitted in the atomizing nozzle 37, a plurality of atomizing micro-holes 372 are uniformly distributed on the atomizing plate 370 along the circumference, and a flow dividing cone 371 is distributed on the inner circumference of the atomizing nozzle 37. Each atomizing micro-hole 372 sequentially includes a gradually expanding flared section 3720 and a gradually tapered necking section 3721 from the inlet to the outlet.

[0040] In this embodiment, the converging section 330 at the end of the liquid inlet branch pipe 33 can accelerate the fluid and increase its kinetic energy, and the fluid is uniformly distributed to each atomizing micro-hole 372 by the flow dividing cone 371. The unique combination of the flared section 3720 and the converging section 3721 of the micro-hole significantly improves the atomization effect, and produces finer and more uniform water mist.

[0041] In one embodiment, the highest point of the pipeline between the connection point of the branch water pipe 22 and the connection point of the mixing tank 32 and the main water pipe 20 is arranged at a position higher than the highest working liquid level of the water tank 2. The branch water pipe 22 is made of transparent or translucent flexible plastic pipe; the end of the main water pipe 20 is in circulation communication with the water tank 2, and the water tank 2 is arranged in one-to-one correspondence with the aeroponic rack 11 and fixedly installed on the main rack body 1.

[0042] In this embodiment, the highest point of the branch water pipe 22 is higher than the liquid level of the water tank 2, which can form a siphon breaking point to prevent water from flowing to the mixing tank 32 due to siphon effect during shutdown, thereby avoiding mis-spraying. The use of transparent or translucent pipe material facilitates direct observation of whether the waterway is unobstructed and the water flow state. The water tank 2 is in one-to-one correspondence with the aeroponic rack 11, which realizes the modularization of the water supply unit and facilitates management and maintenance.

[0043] In operation, first, the external water source supplies water to the water tank 2, and the external air source such as an air compressor provides compressed air to the main air pipe 23. The control system starts the electromagnetic valve according to the humidity sensor signal of the mushroom house. The water in the water tank 2 is delivered through the main water pipe 20 and distributed to each branch water pipe 22 through the three-way joint 21. The branch water pipe 22 delivers water to the water pipe joint 320 on the side wall of the mixing tank 32 of the spray mechanism 3. The compressed air is distributed to each branch air pipe 24 through the three-way joint 21 from the main air pipe 23, and the branch air pipe 24 delivers high-pressure airflow to the air pipe joint 321 at the top of the mixing tank 32. Inside the mixing tank 32, the water flow is sprayed into the throat area of the mixing throat 322 from the water pipe joint 320, and is violently impacted and sheared by the high-speed airflow passing through this place, and is initially broken into fine water vapor mixture. The operator can adjust the gap between the shearing ring 39 and the outlet of the mixing throat 322 by rotating the hand wheel 384 to accurately control the fineness of the atomized particles. The gas-liquid mixture after the initial atomization enters the main cylinder 30 through the connecting pipe 31, and flows along the S-shaped path under the guidance of the S-shaped baffle 34. The large water droplets carried by the mixture are effectively impacted, captured and collected due to the inertial effect; at the same time, the small impurities in the mixture are adsorbed by the activated carbon filter core 35. The collected water droplets and impurities are finally deposited at the bottom of the conical hopper, and the drain plug 36 can be opened regularly for cleaning. The purified gas-liquid mixture enters the multiple liquid inlet branch pipes 33 at the upper part of the main cylinder 30, and after being accelerated at the closed end 330 of the liquid inlet branch pipe 33, the mixture impacts the flow divider cone 371 inside the atomizing nozzle 37 and is uniformly divided into each atomizing micro-hole 372. When the mixture flows through the unique flared section 3720 and the constricted section 3721 of each atomizing micro-hole 372, cavitation effect and severe shearing occur, realizing high-efficiency secondary atomization, and finally extremely fine and uniform water mist is sprayed from all the atomizing nozzles 37, which fully and evenly humidifies the mushrooms on the shelves.

[0044] The above merely describes the specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be encompassed within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
