Description

Technical Field

[0001] This invention relates to the field of gas purification technology, specifically to a ventilation and purification device for a mushroom cultivation chamber. Background Technology

[0002] As a delicate edible fungus that thrives in low to medium temperatures and high humidity, deer antler mushrooms require both natural wild conditions and artificial cultivation. They prefer humid, cool, and well-ventilated environments. During indoor cultivation, the mycelium consumes oxygen and releases carbon dioxide through respiration and metabolism. At the same time, the evaporation of moisture from the substrate produces a large amount of water vapor. In addition, mycelial growth and substrate metabolism also release a small amount of volatile organic gases. These gases tend to accumulate in relatively enclosed cultivation rooms, leading to increased carbon dioxide concentration and excessive humidity, which affects the normal growth of the mycelium. Therefore, it is necessary to regulate and purify the gas through ventilation devices.

[0003] Under normal circumstances, during the mycelial cultivation stage of *Pleurotus eryngii*, the existing ventilation system mainly uses a single ventilation duct to transport purified air from the outside to the cultivation chamber. At the same time, the air inside the chamber is also exhausted. This firstly purifies the air inside the cultivation chamber. However, in the summer in the south, the air temperature is high and the humidity is high. Mycelial respiration is enhanced, the carbon dioxide production rate is accelerated, and metabolism is faster at high temperatures. This continuously generates and accumulates a large amount of heat, further increasing the temperature inside the cultivation chamber. According to the principle that hot air rises and cold air sinks, the hot and humid air continues to rise, forming a high-temperature and high-humidity air layer below the roof. The closer to the top, the higher the temperature and humidity. Furthermore, because the ventilation and purification device is turned on intermittently, the temperature distribution inside the cultivation chamber is uneven, affecting the normal growth of *Pleurotus eryngii*.

[0004] Therefore, intermittent ventilation is adopted, which can replenish oxygen and remove carbon dioxide at regular intervals, and maintain a stable environment with constant temperature, high humidity and gentle airflow in the cultivation room, so as to ensure the normal growth of deer antler mushroom and improve yield and quality.

[0005] Therefore, we propose a ventilation and purification device for the cultivation room of *Agaricus esculentus* to solve the problems mentioned above. Summary of the Invention

[0009] Preferably, the inner wall of the roof is fixedly fitted with multiple mounting boxes, the non-powered exhaust fan is installed inside the mounting box, the top of the mounting box is fixedly connected to an exhaust pipe, one end of the exhaust pipe is fixedly inserted into the interior of the conveying pipe, and the interior of the conveying pipe is connected to the interior of the exhaust pipe.

One end of the lead pipe is fixedly inserted into the interior of the filter device.

[0011] Preferably, the air supply unit further includes multiple connecting pipes and an internal gear belt. The top end of the connecting pipe is fixedly inserted into the interior of the uniform distribution chamber, which is located inside the culture chamber body. The bottom end of the connecting pipe is fixedly inserted into the interior of the diversion chamber, and a uniform distribution plate is fixed between the relative inner walls of the diversion chamber.

[0012] Preferably, the top of the buffer compartment extends into the interior of the distribution compartment, the outer surface of the drive gear ring meshes with the inner wall of the inner gear belt, and a driven gear is fixed to the top of one of the drive gear rings.

[0013] Preferably, a mounting frame is fixed to the bottom surface of the diversion chamber, and a drive motor is fixedly mounted on the top of the mounting frame by screws. A drive shaft is fixedly mounted on the output end of the drive motor, and both ends of the drive shaft extend movably through to the outside of the mounting frame.

[0014] Preferably, a drive gear is fixedly mounted on the outer surface of the drive shaft, and the outer surface of the drive gear meshes with the outer surface of the driven gear. The driven gear is located inside the flow divider.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. During the ventilation process within the cultivation chamber, the content of high-temperature gas at the top of the chamber is detected by the movement of a lightweight float. When the float touches the pressure sensor, indicating a high content of high-temperature gas on the surface and indirectly a high content of carbon dioxide, the fresh air purification device and exhaust equipment are activated to expel the high-temperature gas from the chamber and purify the outside air before delivering it into the cultivation chamber. This air is then gently released through multiple nozzles, accelerating heat exchange while ensuring uniform temperature distribution. Furthermore, it promptly removes high-carbon dioxide content gas from the chamber, solving the problem in existing technologies where the single ventilation duct setup for cultivating *Deer Ear Mushroom* in hot southern environments leads to uneven temperature distribution within the cultivation chamber, affecting the normal growth of *Deer Ear Mushroom*.

[0018] 2. In order to accelerate the heat exchange efficiency of the gas inside the culture chamber, the drive motor is started to drive multiple nozzles to rotate, thereby releasing cold air downwards in multiple directions, accelerating the heat exchange between the cold air and the gas inside the culture chamber, thus accelerating the heat exchange inside the chamber while ensuring the uniformity of the temperature inside the chamber.

[0019] 3. During the exhaust process, the air pump is started, and under the action of negative pressure, multiple non-powered exhaust fans are driven to rotate. The rotation generates centrifugal negative pressure, which automatically extracts the hot and humid air and exhaust gas that remain at the top of the culture chamber and filters and purifies them. The purified gas can then be released outward along the guide pipe to prevent it from polluting the environment. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-9The present invention provides a technical solution: a ventilation and purification device for a mushroom cultivation room, comprising a cultivation room body 1, a fresh air purification device 2 for conveying purified gas outside the cultivation room body 1, an exhaust unit 5 for conveying warm and humid gas from the room to the outside at the top of the cultivation room body 1, the exhaust unit 5 including a non-powered exhaust fan 509 with multiple uniform portions and a lightweight float 506 for detecting the carbon dioxide content at the top of the room, and an air supply unit 6, the air supply unit 6 including a uniform distribution chamber 601 for uniformly distributing fresh air and multiple diversion chambers 603, multiple buffer chambers 605 movably embedded in the bottom surface of the diversion chamber 603, a nozzle 606 for uniformly and gently releasing gas fixedly connected to the bottom of the buffer chamber 605, a drive gear ring 607 for uniformly rotating the nozzle 606 fixedly sleeved on the outer surface of the buffer chamber 605, and the nozzle 606 and the non-powered exhaust fan 509 being staggered.

[0024] During the hot summer months in southern China, the carbon dioxide content increases during the cultivation of antler mushrooms. Based on the principle that hot air rises and cold air sinks, the high-temperature carbon dioxide moves towards the top surface of the cultivation chamber 1, causing uneven temperature distribution within the chamber. As the carbon dioxide moves upward, it is pushed upward by air pressure, causing the lightweight float 506 to move upward and touch the pressure sensor 507. At this point, the pressure sensor 507 is compressed and releases an alarm signal, indicating that the carbon dioxide concentration in the cultivation chamber 1 has reached the required discharge value. The pressure sensor 507 is a mature existing technology and will not be described in detail here. By observing the movement of the lightweight float 506, it is possible to directly determine whether the carbon dioxide content at the top of the cultivation chamber 1 exceeds the standard, providing a direct reflection of changes in the indoor air quality. When the pressure sensor 507 releases an alarm signal, the rotation of multiple non-powered exhaust fans 509 generates negative pressure, which can extract the high-temperature carbon dioxide suspended at the top of the culture chamber body 1. The non-powered exhaust fan 509 consists of turbine rotating blades and a central rotating shaft. When gas is drawn into the mounting box 508, the air is drawn upward and washes the inclined surface of the blades. The blades are deflected by force and generate rotational force, thereby realizing the rotation of the non-powered exhaust fan 509. The rotating non-powered exhaust fan 509 can extract the gas in the culture chamber body 1, thereby achieving the purpose of quickly removing the high humidity and high temperature gas in the room. While drawing in indoor air, the fresh air purification device 2 is activated to draw in outdoor air. After filtration, purification, and cooling, the fresh purified air is delivered into the cultivation chamber 1, purifying the air inside the chamber. The fresh air purification device 2 employs a three-stage filtration, refrigeration and dehumidification, and surface cooling integrated structure. It removes dust, bacteria, and microorganisms from the air through primary, medium, and high-efficiency filtration. The synergistic effect of refrigeration and dehumidification, combined with adsorption drying, reduces the relative humidity to 60%–70%. Surface cooling then stabilizes the fresh air at 18–22℃, ultimately delivering clean, dry, and constant-temperature fresh air into the cultivation chamber 1 to meet the growth requirements of the antler mushroom. The stage has stringent environmental requirements, and its model is: Jinfit QSB15FC. To ensure a more uniform distribution of fresh air and prevent interference between input and output gases, achieving rapid homogenization of the indoor air, after the external gas enters the culture chamber body 1, it is first evenly distributed by the equalization chamber 601. The equalization chamber 601 is an existing mature technology and will not be described in detail here. The evenly distributed fresh air enters multiple diversion chambers 603 and then enters multiple buffer chambers 605. Since the inner diameter of the buffer chamber 605 is larger than the inner diameter of the nozzle 606, the setting of the buffer chamber 605 ensures that the gas released by the nozzle 606 is in a gentle state. Figure 8 As shown, the opening of nozzle 606 faces downwards. Fresh, low-temperature gas flows downwards along the outlet of nozzle 606. Cold air, being heavier, sinks, while hot air, being lighter, rises. During the downward pressure of the cold air, to accelerate the heat exchange efficiency of the gas inside the cultivation chamber 1, the drive gear ring 607 rotates, causing multiple nozzles 606 to rotate, thus releasing cold air downwards in multiple directions. The range of gas released by the rotating nozzle 606 does not overlap with the path of the gas drawn by the non-powered exhaust fan 509, and the two do not interfere with each other. Through the rotation of nozzle 606, the heat exchange between the cold air and the gas inside the cultivation chamber 1 is accelerated. After the heat exchange, the gas is heated and then moves upwards to the exhaust vent. This accelerates the heat exchange inside the chamber while ensuring the uniformity of the indoor temperature. It can also promptly output the high carbon dioxide content gas inside the chamber, solving the problem in the existing technology where the single ventilation duct setting for cultivating deer ear mushrooms in the high-heat environment of southern regions leads to uneven temperature distribution in the cultivation chamber, affecting the normal growth of deer ear mushrooms.

[0025] like Figures 1-6As shown, the exhaust unit 5 also includes a roof 501 and a conveying pipe 511. The bottom of the roof 501 is fixedly connected to the top of the culture chamber body 1. A top-mounted float installation chamber 503 is fixedly embedded in the inner wall of the roof 501. A connecting rod 504 is fixed between the relative inner walls of the top-mounted float installation chamber 503. A spring 505 is provided on the top of the connecting rod 504. One end of the spring 505 is fixedly connected to the outer surface of the connecting rod 504, and the other end of the spring 505 is fixedly connected to the outer surface of the lightweight float 506. A pressure sensor 507 is provided on the inner top surface of the top-mounted float installation chamber 503.

[0026] Among them, spring 505 provides support for lightweight float 506, and as... Figure 4 As shown, since the internal cross-section of the top-mounted float installation chamber 503 is trapezoidal and the top of the top-mounted float installation chamber 503 is higher than the top of the culture chamber body 1, high-temperature gas will accumulate in the top-mounted float installation chamber 503, making the movement of the lightweight float 506 more obvious. When the high-temperature gas enters the top-mounted float installation chamber 503 upward, it will drive the lightweight float 506 upward under the push of the gas. When the lightweight float 506 touches the pressure sensor 507, it indicates that the carbon dioxide content in the upper layer of the culture chamber body 1 is too high and the indoor temperature distribution is uneven. It is necessary to start the exhaust unit 5 and the air supply unit 6 to ventilate and exchange the indoor gas.

[0027] like Figures 1-6 As shown, multiple mounting boxes 508 are fixedly fitted into the inner wall of the roof 501. A non-powered exhaust fan 509 is installed inside the mounting box 508. An exhaust pipe 510 is fixedly connected to the top of the mounting box 508. One end of the exhaust pipe 510 is fixedly connected to the inside of the conveying pipe 511. The inside of the conveying pipe 511 is connected to the inside of the exhaust pipe 510. A filter device 512 is fixedly connected to the outer surface of the conveying pipe 511. An air pump 502 is installed on the top of the roof 501. The output end of the air pump 502 is fixedly connected to a delivery pipe 513. One end of the delivery pipe 513 is fixedly connected to the inside of the filter device 512.

[0028] During the process of expelling the high-temperature gas inside the culture chamber 1, the air pump 502 is first started to draw gas into the inlet pipe 513, and then draw gas into multiple installation boxes 508. Under the action of negative pressure, multiple non-powered exhaust fans 509 are driven to rotate. The rotation generates centrifugal negative pressure, which automatically draws the humid and hot air and exhaust gas that are stuck at the top of the culture chamber 1 to the outside. The gas then enters the activated carbon in the filter device 512 along the delivery pipe 511 to filter the extracted gas, adsorbing the bacteria in the gas. The purified gas can then be released outward along the inlet pipe 513.

[0029] like Figure 2 , Figures 6-9As shown, the air supply unit 6 also includes multiple connecting pipes 602 and an internal gear belt 608. The top end of the connecting pipe 602 is fixedly inserted into the interior of the uniform distribution chamber 601, which is located inside the culture chamber body 1. The bottom end of the connecting pipe 602 is fixedly inserted into the interior of the diversion chamber 603, and a uniform distribution plate 604 is fixed between the relative inner walls of the diversion chamber 603.

[0030] After being treated by the outside environment, the fresh air is distributed into multiple connecting pipes 602 through the equalization chamber 601, and then evenly introduced into the interior of multiple distribution chambers 603. The equalization plate 604 then distributes the air evenly again, ensuring uniform delivery to the corresponding buffer chambers 605. For example... Figure 8 As shown, the surface of the uniform distribution plate 604 has multiple round holes evenly distributed to achieve uniform gas distribution, and the upper part of the diversion chamber 603 is shaped like the number eight to achieve uniform gas diversion.

[0031] like Figure 2 , Figures 6-9 As shown, the top of the buffer chamber 605 extends movably into the interior of the diversion chamber 603. The outer surface of the drive gear ring 607 meshes with the inner wall of the internal gear belt 608. A driven gear 609 is fixed to the top of one of the drive gear rings 607. A mounting bracket 610 is fixed to the bottom surface of the interior of the diversion chamber 603. A drive motor 611 is fixedly mounted on the top of the mounting bracket 610 by screws. A drive shaft 612 is fixedly mounted on the output end of the drive motor 611. Both ends of the drive shaft 612 extend movably into the exterior of the mounting bracket 610. A drive gear 613 is fixedly mounted on the outer surface of the drive shaft 612. The outer surface of the drive gear 613 meshes with the outer surface of the driven gear 609. The driven gear 609 is located inside the diversion chamber 603.

[0032] During the rotation of the nozzle 606, the drive motor 611 is first started, which drives the drive shaft 612 to rotate, thereby driving the drive gear 613 to rotate, which in turn drives the corresponding driven gear 609 to rotate, which in turn drives the drive gear ring 607 connected to it to rotate, which in turn drives the gear belt 608 inside the rod to rotate, which in turn drives all the corresponding drive gear rings 607 to rotate, which in turn drives the buffer chamber 605 to rotate, which in turn drives multiple nozzles 606 to rotate, thereby achieving the purpose of uniformly releasing fresh gas into the culture chamber body 1.

[0033] like Figure 2 , Figures 6-9 As shown, a support rod 614 is fixed between the relative inner walls of the culture chamber body 1. A cylinder 615 is provided at the top of the support rod 614. A connecting frame 616 is fixedly installed at the top of the cylinder 615. The top of the connecting frame 616 is fixedly connected to the bottom of the uniform distribution chamber 601.

[0034] Since the high-temperature gas in the main body 1 of the cultivation chamber is mostly concentrated within a range of 30-60cm from the bottom surface of the roof 501, during the fruiting period, when the multi-point temperature recorder 7 detects a high moisture content in the main body 1 of the cultivation chamber, the cylinder 615 can be activated to shorten it, driving the connecting frame 616 to move downwards, which in turn drives the uniform distribution chamber 601 to move downwards, thereby driving multiple nozzles 606 to move downwards. When the nozzles 606 move downwards to a position 30-60cm from the bottom surface of the roof 501, the cold air sinks and compresses the hot air upwards, resulting in faster heat and moisture removal. During the mycelial stage, in order to prevent the fresh air from being too close to the antler mushroom vertically and affecting its normal growth, the cylinder 615 can be activated again to extend it, driving multiple nozzles 606 to move upwards to a position 10cm-20cm from the top of the main body 1 of the cultivation chamber, thus making the incoming fresh air farther away from the antler mushroom, achieving the purpose of gentle air delivery to the antler mushroom. By adjusting the position of the nozzles 606, the air intake system can be flexibly changed according to the different growth stages of the antler mushroom.

[0035] like Figure 2 , Figures 6-9 As shown, the output end of the fresh air purification device 2 is fixedly connected to the input pipe 3, and an elastic sealing plate 4 is set between the relative inner walls of the culture chamber body 1. One end of the input pipe 3 passes through the elastic sealing plate 4 to the interior of the uniform distribution chamber 601. The outer surface of the input pipe 3 is fixedly connected to the inner wall of the elastic sealing plate 4. Multiple multi-point temperature recorders 7 are set inside the culture chamber body 1.

[0036] Among them, such as Figure 1 As shown, the input pipe 3 consists of a rigid pipe and a corrugated pipe that can extend and retract vertically. Its purpose is to facilitate the vertical movement of the uniform distribution chamber 601. The elastic sealing plate 4 is made of soft rubber, and its deformation can adapt to changes within a 60cm range vertically of the uniform distribution chamber 601. The multi-point temperature recorder 7 uses a multi-channel temperature and humidity monitoring instrument to perform layered detection of the vertical space of the culture chamber. By deploying independent sensors at different heights in the upper, middle, and lower parts of the culture chamber body 1, the temperature and humidity of each layer can be collected and compared synchronously to accurately determine the thickness and distribution of the top humid air layer, providing data for the height adjustment of the nozzle 606 and improving the accuracy of ventilation and purification control. Its model is: Jianda Renke RS-WS-N01 multi-channel temperature and humidity monitoring system. Through the setting of the multi-point temperature recorder 7, the temperature and humidity in the culture chamber body 1 can be monitored in real time.

[0037] The operating principle and usage of this device are as follows: During the hot summer months in southern China, the carbon dioxide content produced during the cultivation of *Deer Antler Mushroom* increases, and the mushroom itself is at a high temperature, causing it to rise. This, in turn, causes the lightweight float 506 to move upward under air pressure, touching the pressure sensor 507. This indicates that the carbon dioxide concentration inside the cultivation chamber 1 is high, and the high-temperature gas has reached the required discharge value. At this point, the air pump 502 is activated to draw gas into the inlet pipe 513. Under negative pressure, multiple non-powered exhaust fans 509 rotate, generating centrifugal negative pressure. This automatically draws out the humid and hot air and exhaust gas trapped at the top of the cultivation chamber 1. The extracted gas is then filtered by the filter device 512, which adsorbs bacteria and releases clean air. Simultaneously, the fresh air purification device 2 is activated to draw out and purify the gas, then lowers it to the required temperature. The gas is then evenly distributed into multiple distribution chambers 603 through the uniform distribution chamber 601, and finally evenly distributed into multiple buffer chambers through the small holes on the surface of the uniform distribution plate 604. Inside 605, the gas is released outward through nozzle 606. Then, multiple drive motors 611 are activated, causing their corresponding drive gear rings 607 to rotate. This, in turn, drives the gear belt 608 inside the drive rod to rotate, causing all the corresponding drive gear rings 607 to rotate. This, in turn, causes multiple nozzles 606 to rotate, uniformly releasing fresh gas into the culture chamber body 1. The fresh, low-temperature gas flows downward along the air outlet of nozzle 606, with the heavier cold air sinking and the lighter hot air rising. The rotation of nozzle 606 accelerates the interaction between the cold gas and the culture medium. Heat exchange occurs within the main body 1 of the chamber. After the heat exchange, the gas is heated and then moves upwards to the position of the non-powered exhaust fan 509. It is then drawn out of the main body 1 of the cultivation chamber by the suction force generated by the rotation of the non-powered exhaust fan 509. In addition, at different growth stages of the antler mushroom, in order to adapt the vertical distance between the nozzle 606 and the antler mushroom to the growth stage, the cylinder 615 is extended and retracted to drive the uniform distribution chamber 601 to move upwards or downwards, thereby driving the nozzle 606 to move upwards or downwards, so that the nozzle 606 can be matched with different growth environments.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
