Description

Technical Field

[0001] This invention belongs to the technical field of edible fungi cultivation equipment, specifically a constant temperature and humidity cultivation box for edible fungi and its preservation method. Background Technology

[0002] Edible fungi are rich in protein, dietary fiber, vitamins, and various minerals. They are not only delicious but also possess nutritional and health benefits, making them highly popular among consumers. In recent years, with increased health awareness and a deeper understanding of edible fungi, market demand has continued to grow. To meet market supply and improve the yield and quality of edible fungi, cultivation techniques are constantly being innovated, and the constant temperature and humidity growing box has emerged as a significant innovative achievement. A search revealed patent CN222030799U, which describes a constant temperature and humidity cultivation box for edible fungi. The box includes a body with a door hinged to one side of the opening. A spotlight is installed on the top of the box. A placement rack is located at the bottom of the inner wall of the box, with several placement slots on the top of the rack. A ventilation mesh is installed at the bottom of the inner wall of each placement slot. Irregularly shaped clamps are slidably connected to the top of both sides of the inner wall of each placement slot. A return spring is installed between the irregularly shaped clamps and the placement slot. A diversion spray pipe is embedded in the middle of the inner wall of the box. A water tank is located on one side of the box, and a water pump is located at the bottom of the water tank. The water pump outlet is sealed and connected to one end of the diversion spray pipe. This invention provides a constant temperature and humidity cultivation box for edible fungi. A timer controls the water pump, pumping water at specific times. The water pump draws water into the diversion spray pipe, and a flow-limiting solenoid valve limits the water flow. The fungi are then irrigated using drip irrigation nozzles. During the vigorous growth stage of edible fungi fruiting bodies, increased respiration releases a large amount of water vapor. For example, when oyster mushrooms grow rapidly, the evaporation of moisture from the mushroom surface and the water vapor produced by respiration cause a sharp increase in humidity inside the container. If the humidity is too high, it will inhibit the growth of edible fungi and also easily lead to the growth of miscellaneous bacteria and diseases. Traditional growing boxes mainly rely on ventilation to dehumidify. However, on rainy and foggy days, the air humidity is close to saturation. Ventilation not only fails to effectively reduce the humidity inside the box, but also brings in more moisture, further increasing the humidity inside the box and seriously affecting the growth of edible fungi. Summary of the Invention

[0003] The purpose of this invention is to provide a constant temperature and humidity cultivation box for edible fungi and its preservation method, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a constant temperature and humidity cultivation box for edible fungi, comprising a box body, a box door hinged to one side of the box body, a diversion spray pipe installed inside the box body, a placement rack arranged below the diversion spray pipe, a first collection box arranged below the placement rack, and a dehumidification component arranged inside the box body. The dehumidification assembly includes an exhaust fan located inside the housing. A dehumidification chamber and a recovery chamber are located on one side of the exhaust fan. Both the dehumidification chamber and the recovery chamber are located inside the housing. A control assembly is located between the dehumidification chamber and the recovery chamber. A condenser is installed inside the dehumidification chamber. A drainage assembly is located on one side of the condenser. Exhaust vents are evenly connected to the bottom of the recovery chamber.

[0005] As a further technical solution of the present invention, the drainage component includes a scraper disposed on one side of the condenser, a movable seat is installed at one end of the scraper, and a reciprocating screw is threadedly connected to the inner wall of the movable seat, and the reciprocating screw is rotatably installed on the inner wall of the housing. A ring gear is fixedly installed on the outer wall of the exhaust fan. A first gear is meshed with the top of the ring gear. A drive shaft is fixedly installed on the inner wall of the first gear. A first bevel gear is fixedly connected to the end of the drive shaft away from the first gear. A second bevel gear is meshed with the bottom end of the first bevel gear. The second bevel gear is fixedly installed on the top of the reciprocating screw.

[0006] As a further technical solution of the present invention, the inner wall of the scraper is provided with through holes, and the through holes are evenly distributed.

[0007] As a further technical solution of the present invention, the control component includes a control plate disposed between the dehumidification chamber and the recovery chamber, and the control plate is uniformly installed in a ring on the outer wall of the rotating shaft; A second gear is fixedly installed on the outer wall of the rotating shaft. A rack plate is provided above the second gear. A connecting plate is fixedly connected to one side of the rack plate. The connecting plate is installed on the inner wall of the movable seat.

[0008] As a further technical solution of the present invention, a first magnetic block and a second magnetic block are provided on one side below the connecting plate, and both the first magnetic block and the second magnetic block are fixedly installed on the inner wall of the box.

[0009] As a further technical solution of the present invention, a second collection box is provided below the control panel, and the second collection box is slidably installed inside the box.

[0010] As a further technical solution of the present invention, the connecting plate and the movable seat are slidably connected.

[0011] As a further technical solution of the present invention, the connecting plate is fixedly installed on one side of the scraper.

[0012] As a further technical solution of the present invention, the top opening diameter of the recovery chamber is smaller than the inner wall diameter of the recovery chamber.

[0013] A method for preserving edible fungi in a constant temperature and humidity cultivation box includes the following steps: S1: When dehumidification is required inside the planting box, start the exhaust fan and condenser. The gas inside the box enters the dehumidification chamber. The gas comes into contact with the condenser, and the water vapor in the air reaches a saturated state due to the temperature drop, and then condenses into liquid water. The dehumidified gas returns to the box through the exhaust port. S2: When the exhaust fan starts, it drives the ring gear to rotate. The rotation of the ring gear drives the rotation of the first gear. The rotation of the first gear drives the rotation of the transmission shaft. The rotation of the transmission shaft drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the reciprocating screw. When the reciprocating screw rotates, it drives the moving seat to move up and down. The movement of the moving seat drives the movement of the scraper. During the downward movement, the scraper contacts the surface of the condenser and scrapes the water droplets attached to the outer wall of the condenser down into the control panel. S3: When the scraper moves down, it drives the connecting plate to move down. When the connecting plate moves to one end of the first magnetic block, the two attract each other. At the same time, the movement of the connecting plate drives the rack plate to move, so that the rack plate and the second gear are at the same level. S4: When the scraper moves upward, the rack plate contacts the second gear and causes it to rotate. The rotation of the second gear causes the rotating shaft to rotate, and the rotation of the rotating shaft causes the control plate to rotate, discharging the condensate collected on the top of the control plate. This allows the condensate to move from the dehumidification chamber to the recovery chamber and finally fall into the second collection box for collection.

[0014] The beneficial effects of this invention are as follows: This invention utilizes a dehumidification component. When dehumidification is needed inside the cultivation box, the exhaust fan and condenser are activated. Gas inside the box enters the dehumidification chamber, where it comes into contact with the condenser. As the temperature decreases, the water vapor in the air reaches saturation and condenses into liquid water. The dehumidified gas then returns to the box through the exhaust vent. Compared to traditional ventilation methods, condensation dehumidification effectively reduces humidity and maintains a suitable growth environment for edible fungi. The bottom opening of the exhaust vent is located below the placement rack, which effectively reduces the humidity gradient and provides a more stable growth environment for edible fungi.

[0015] This invention utilizes a drainage assembly. During operation, the exhaust fan activates, driving a ring gear. This ring gear, in turn, drives a first gear, which in turn drives a transmission shaft. This transmission shaft, in turn, drives a first bevel gear, which in turn drives a second bevel gear. The second bevel gear, in turn, drives a reciprocating screw. The reciprocating screw's rotation causes a moving base to move up and down, which in turn moves a scraper. As the scraper moves downwards, it contacts the condenser surface, effectively removing water droplets adhering to the condenser's outer wall. This prevents the formation of a water film on the condenser surface, which increases thermal resistance between the air and the condenser, hindering heat transfer and reducing cooling efficiency. Timely removal of condensate keeps the condenser surface dry, allowing direct contact between humid air and the condenser, improving heat exchange efficiency and accelerating dehumidification.

[0016] This invention, through the configuration of the control components, allows the connecting plate to move downwards during operation. The movement of the connecting plate, in turn, causes the rack plate to move, which in turn causes the second gear to rotate. The rotation of the second gear, in turn, causes the rotating shaft to rotate, which in turn causes the control plate to rotate. This discharges the condensate collected at the top of the control plate, moving the condensate from the dehumidification chamber to the recovery chamber, thus preventing the condensate from frosting or freezing.

[0018] 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.

[0019] like Figures 1 to 7 As shown in the embodiment of the present invention, a constant temperature and humidity cultivation box for edible fungi includes a box body 1, a box door 5 hinged to one side of the box body 1, a diversion spray pipe 2 installed inside the box body 1, a placement rack 3 arranged below the diversion spray pipe 2, a first collection box 4 arranged below the placement rack 3, and a dehumidification component arranged inside the box body 1. The dehumidification assembly includes an exhaust fan 7 installed inside the housing 1. A dehumidification chamber 26 and a recovery chamber 27 are provided on one side of the exhaust fan 7. Both the dehumidification chamber 26 and the recovery chamber 27 are located inside the housing 1. A control assembly is provided between the dehumidification chamber 26 and the recovery chamber 27. A condenser 6 is installed inside the dehumidification chamber 26. A drainage assembly is provided on one side of the condenser 6. Exhaust holes 22 are evenly connected to the bottom of the recovery chamber 27.

[0020] The existing patent CN222030799U discloses a constant temperature and humidity cultivation box for edible fungi. This patent discloses the box body 1, the diversion spray pipe 2, the placement rack 3, the first collection box 4, and the box door 5 proposed in this application. The technical means will not be described in detail here. When dehumidification is required inside the planting box, the exhaust fan 7 and condenser 6 are turned on. The gas inside the box 1 enters the dehumidification chamber 26. The gas comes into contact with the condenser 6, and the water vapor in the air reaches saturation due to the temperature drop, and then condenses into liquid water. The dehumidified gas returns to the box 1 through the exhaust port 22. Compared with the traditional ventilation method, condensation dehumidification can effectively reduce humidity and maintain a suitable growth environment for edible fungi. The bottom opening of the vent 22 is located below the placement rack 3, which can effectively reduce the humidity gradient and provide a more stable growth environment for edible fungi.

[0021] like Figures 1 to 7 As shown, the drainage assembly includes a scraper 15 disposed on one side of the condenser 6, a movable seat 14 mounted on one end of the scraper 15, and a reciprocating screw 13 threadedly connected to the inner wall of the movable seat 14, the reciprocating screw 13 being rotatably mounted on the inner wall of the housing 1. A ring gear 8 is fixedly installed on the outer wall of the exhaust fan 7. A first gear 9 is meshed with the top of the ring gear 8. A drive shaft 10 is fixedly installed on the inner wall of the first gear 9. A first bevel gear 11 is fixedly connected to the end of the drive shaft 10 away from the first gear 9. A second bevel gear 12 is meshed with the bottom of the first bevel gear 11. The second bevel gear 12 is fixedly installed on the top of the reciprocating screw 13.

[0022] During operation, the exhaust fan 7 starts, driving the ring gear 8 to rotate. The rotation of the ring gear 8 drives the first gear 9 to rotate, which in turn drives the transmission shaft 10 to rotate. The rotation of the transmission shaft 10 drives the first bevel gear 11 to rotate, which in turn drives the second bevel gear 12 to rotate. The rotation of the second bevel gear 12 drives the reciprocating screw 13 to rotate. When the reciprocating screw 13 rotates, it drives the moving seat 14 to move up and down. The movement of the moving seat 14 drives the scraper 15 to move. As the scraper 15 moves downward, it comes into contact with the surface of the condenser 6, which helps to scrape off the water droplets adhering to the outer wall of the condenser 6. This prevents the formation of a water film if condensate adheres to the surface of the condenser 6 for a long time. This water film increases the thermal resistance between the air and the condenser 6, hindering heat transfer and reducing the cooling effect of the condenser 6. Timely scraping away of condensate keeps the surface of the condenser 6 dry, allowing humid air to directly contact the condenser 6, improving heat exchange efficiency, and thus accelerating the dehumidification speed. The scraper 15 is made of rubber on the side near the condenser 6. The rubber scraper 15 is soft and elastic, and can fit closely to the surface of the condenser 6 to effectively scrape off water droplets.

[0023] like Figures 1 to 7 As shown, the inner wall of the scraper 15 has through holes 16, which are evenly distributed.

[0024] The through hole 16 can serve as a drainage channel. When the scraper 15 scrapes away the condensate, the water can be quickly discharged through the through hole 16, preventing water from accumulating on the surface of the movable seat 14. This prevents the scraper 15 from carrying the water back to the surface of the condenser 6, which helps to keep the surface of the condenser 6 dry and further improves the dehumidification effect.

[0025] like Figure 6 As shown, the control assembly includes a control plate 21 disposed between the dehumidification chamber 26 and the recovery chamber 27. The control plate 21 is uniformly installed in a ring on the outer wall of the rotating shaft 20. A second gear 19 is fixedly installed on the outer wall of the rotating shaft 20. A rack plate 18 is provided above the second gear 19. A connecting plate 17 is fixedly connected to one side of the rack plate 18. The connecting plate 17 is installed on the inner wall of the movable seat 14.

[0026] During operation, when the scraper 15 moves downward, it drives the connecting plate 17 to move downward. The movement of the connecting plate 17 drives the movement of the rack plate 18. The movement of the rack plate 18 drives the rotation of the second gear 19. The rotation of the second gear 19 drives the rotation of the rotating shaft 20. The rotation of the rotating shaft 20 drives the rotation of the control plate 21, which discharges the condensate collected at the top of the control plate 21 and moves the condensate from the dehumidification chamber 26 to the recovery chamber 27, preventing the condensate from frosting or freezing.

[0027] Such as 4 and Figure 5 As shown, a first magnetic block 24 and a second magnetic block 25 are provided on one side below the connecting plate 17. Both the first magnetic block 24 and the second magnetic block 25 are fixedly installed on the inner wall of the box 1.

[0028] The bottom end of the connecting plate 17 is magnetically connected to both the first magnetic block 24 and the second magnetic block 25. The rack plate 18 repels the first magnetic block 24 and attracts the second magnetic block 25. The second magnetic block 25 is disposed on one side below the second gear 19, so that the rack plate 18 does not contact the second gear 19 for transmission when the connecting plate 17 moves down; During operation, when the scraper 15 moves down, it drives the connecting plate 17 to move down. When the connecting plate 17 moves to one end of the first magnetic block 24, the two attract each other. The movement of the connecting plate 17 drives the rack plate 18 to move, so that the rack plate 18 and the second gear 19 are at the same level. When the scraper 15 moves upward, the rack 18 contacts the second gear 19 and causes it to rotate. The rotation of the second gear 19 causes the rotating shaft 20 to rotate, and the rotation of the rotating shaft 20 causes the control plate 21 to rotate, thus discharging the condensate collected at the top of the control plate 21 and allowing the scraper 15 to scrape the water before draining the water.

[0029] like Figure 4 As shown, a second collection box 23 is provided below the control panel 21, and the second collection box 23 is slidably installed inside the box body 1.

[0030] Condensate is collected through the second collection box 23 and can be directly slid out from the recovery chamber 27.

[0031] like Figure 6 As shown, the connecting plate 17 and the movable seat 14 are slidably connected.

[0032] like Figure 6 As shown, the connecting plate 17 is fixedly installed on one side of the scraper 15.

[0033] like Figure 7 As shown, the top opening diameter of the recovery chamber 27 is smaller than the inner wall diameter of the recovery chamber 27.

[0034] The bottom of the control plate 21 does not contact the inner wall of the recovery chamber 27. When the control plate 21 is rotated to drain water, the condensate on the surface of the control plate 21 can be discharged from the gap between the control plate 21 and the recovery chamber 27 along the inclined surface of the control plate 21.

[0035] A method for preserving edible fungi in a constant temperature and humidity cultivation box includes the following steps: S1: When dehumidification is required in the planting box, start the exhaust fan 7 and condenser 6. The gas inside the box 1 enters the dehumidification chamber 26. The gas comes into contact with the condenser 6. The water vapor in the air reaches saturation due to the temperature drop and then condenses into liquid water. The dehumidified gas returns to the box 1 through the exhaust port 22. S2: When the exhaust fan 7 starts, it drives the ring gear 8 to rotate. The rotation of the ring gear 8 drives the first gear 9 to rotate. The rotation of the first gear 9 drives the transmission shaft 10 to rotate. The rotation of the transmission shaft 10 drives the first bevel gear 11 to rotate. The rotation of the first bevel gear 11 drives the second bevel gear 12 to rotate. The rotation of the second bevel gear 12 drives the reciprocating screw 13 to rotate. When the reciprocating screw 13 rotates, it drives the moving seat 14 to move up and down reciprocally. The movement of the moving seat 14 drives the scraper 15 to move. During the downward movement, the scraper 15 contacts the surface of the condenser 6 and scrapes the water droplets attached to the outer wall of the condenser 6 into the control panel 21. S3: When the scraper 15 moves down, it drives the connecting plate 17 to move down. When the connecting plate 17 moves to one end of the first magnetic block 24, the two attract each other. At the same time, the movement of the connecting plate 17 drives the rack plate 18 to move, so that the rack plate 18 and the second gear 19 are at the same level. S4: When the scraper 15 moves upward, the rack 18 contacts the second gear 19 and causes it to rotate. The rotation of the second gear 19 causes the rotation of the rotating shaft 20. The rotation of the rotating shaft 20 causes the control plate 21 to rotate, discharging the condensate collected at the top of the control plate 21. The condensate moves from the dehumidification chamber 26 to the recovery chamber 27 and finally falls into the second collection box 23 for collection.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
