[0049] Among them, reference Figure 1 and Figure 2 The tobacco fermentation box 10 provided by the embodiment of the present invention is used to ferment tobacco leaves 20 placed inside the box 100. After the tobacco leaves 20 are fermented, defects can be reduced and they can be used to produce cigarettes. Figure 1 and Figure 2 The tobacco fermentation box 10 includes a box body 100 and a tobacco placement plate 200 placed inside the box body 100. The tobacco placement plate 100 is used to place tobacco leaves 20. The box body 100 provides the required environment for the fermentation of tobacco leaves 20. It should be noted that the tobacco leaves 20 are placed on the tobacco placement plate 100. Figure 1 and Figure 2 The tobacco leaves 20 are placed in a relatively regular manner for easy observation. However, in actual production, the placement of the tobacco leaves 20 is random. As long as the tobacco leaves 20 can be fermented, there is no specific limitation on the placement of the tobacco leaves 20 on the tobacco leaf placement plate 100. Figure 1 As shown, multiple tobacco leaf placement plates 200 can be set in a box 100, which can achieve synchronous fermentation of more tobacco leaves 20. Figure 1 The three tobacco leaf placement plates 200 are shown in the figure. The number of specific tobacco leaf placement plates 200 can be adjusted according to actual needs.

[0050] For further reference, Figure 1 and Figure 2 As shown, the tobacco fermentation box 10 includes a detection module 300, which is disposed on a side wall inside the box 100. The detection module 300 can detect environmental factors inside the box 100, thereby ensuring that the tobacco leaves 20 are in a state conducive to fermentation. Optionally, the specific side wall of the box 100 on which the detection module 300 is disposed can be adaptively adjusted according to actual needs, and this embodiment of the present invention does not specifically limit this.

[0051] Specifically, refer to Figure 1 and Figure 2 As shown, the detection module 300 includes a temperature detection unit 310 and a humidity detection unit 320, wherein the temperature detection unit 310 is used to detect the temperature information inside the box 100, and the humidity detection unit 320 is used to detect the humidity information inside the box 100. The temperature detection unit 310 and the humidity detection unit 320 are used to detect environmental factors inside the box 100, and can determine whether the current fermentation of the tobacco leaves 20 is suitable based on the temperature information and the humidity information. Optionally, the box 100 can include multiple temperature detection units 310 and multiple humidity detection units 320, and the number of temperature detection units 310 and humidity detection units 320 provided corresponds to the number of tobacco placement plates 200 provided. Figure 1 In the figure, three tobacco placement plates 200, three temperature detection units 310 and three humidity detection units 320 are used as an example. Each temperature detection unit 310 and each humidity detection unit 320 can detect the temperature and humidity around the tobacco placement plate 200.

[0052] For further reference, Figure 1 and Figure 2 As shown, the tobacco fermentation box 10 also includes an adjustment module 400. The adjustment module 400 can adjust the environmental factors (humidity and temperature, etc.) inside the box 100 and adjust the placement of the tobacco leaves 20, so as to ensure that the tobacco leaves 20 are in the best fermentation state. In other words, if the temperature of the tobacco leaves 20 is too low or too high, or the humidity is too wet or too dry, it will affect the fermentation of the tobacco leaves 20. Therefore, precise control of the temperature and humidity of the environment in which the tobacco leaves 20 are located is an important factor in ensuring the fermentation of the tobacco leaves 20. Specifically, the adjustment module 400 includes a heating unit 410 and a humidifying unit 420, wherein the heating unit 410 and the humidifying unit 420 are arranged inside the box 100, refer to Figure 1 and Figure 2As shown, the heating unit 410 and the humidifying unit 420 are disposed on the top sidewalls of the housing 100. The specific locations of the heating unit 410 and the humidifying unit 420 can be adaptively adjusted based on actual process requirements. The heating unit 410 can generate heat, and the temperature inside the housing 100 is adjusted based on the heat generated by the heating unit 410; the humidifying unit 420 can generate water vapor, and the humidity inside the housing 100 is adjusted based on the water vapor generated by the humidifying unit 420. By regulating the heating unit 410 and the humidifying unit 420, the temperature and humidity inside the housing 100 can be ensured to be at a temperature and humidity suitable for the fermentation of the tobacco leaves 20, thereby ensuring the fermentation effect of the tobacco leaves 20. Optionally, the number of heating units 410 and humidifying units 420 provided in the housing 100 can be adaptively adjusted, and the number of heating units 410 and humidifying units 420 provided can also correspond one-to-one with the number of tobacco leaf placement plates 200 provided. Figure 1 The example includes three tobacco leaf placement plates 200, three temperature detection units 310, three humidity detection units 320, three heating units 410 and three humidification units 420. Each heating unit 410 and each humidification unit 420 can adjust the temperature and humidity around the tobacco leaf placement plate 200 to ensure that the ambient temperature and ambient humidity of the tobacco leaves 20 are suitable for the fermentation of the tobacco leaves 20.

[0053] For further reference, Figure 1 and Figure 2 As shown, the adjustment module 400 also includes a position adjustment unit 430, which is located inside the box 100 and is connected to the tobacco placement plate 200. When the position adjustment unit 430 is in position adjustment, the position adjustment unit 430 will drive the tobacco placement plate 200 to adjust its position. That is, the position adjustment unit 430 can drive the position adjustment of the tobacco placement plate 200 according to the adjustment of its own position, thereby adjusting the position of the tobacco leaves 20. By changing the position or angle of the position adjustment unit 430, the tobacco leaves 20 can be driven to change their position or angle, thereby ensuring the fermentation of the tobacco leaves 20 at multiple angles and dimensions, and ensuring the fermentation conditions of the tobacco leaves 20. For example, when the heating unit 410 and the humidifying unit 420 adjust the temperature and humidity, the position adjustment unit 430 can drive the tobacco leaves 20 to change their angles, thereby ensuring the fermentation uniformity of the tobacco leaves 20 and ensuring the fermentation effect of the tobacco leaves 20.

[0054] For further reference, Figures 1 to 3As shown, the tobacco fermentation box 10 further includes a control module 500, which is connected to the detection module 300 and the regulation module 400, respectively. It can be understood that the control module 500 can control the detection module 300 to perform detection and adjust the regulation module according to the information detected by the detection module 300. Optionally, the control module 500 can be a programmable logic controller (PLC), which controls various types of mechanical equipment or production processes through digital or analog input and output.

[0055] Specifically, refer to Figure 3 As shown, the control module 500 is connected to the temperature detection unit 310. The control module 500 can control the temperature detection module 310 to detect the temperature of the box 100, and the temperature information generated by the temperature detection module 310 is transmitted to the control module 500. Furthermore, the control module 500 is also connected to the heating unit 410. The control module 500 can control the heating unit 410 to generate heat. Specifically, the control module 500 can control the heating unit 410 to generate appropriate heat based on the obtained temperature information, thereby adjusting the internal ambient temperature of the box 100 to a temperature suitable for the fermentation of the tobacco leaves 20. For example, if the temperature suitable for the fermentation of the tobacco leaves 20 is 30 degrees Celsius to 38 degrees Celsius, the control module 500 controls the temperature detection unit 310 to detect the temperature, and the temperature detection unit 310 detects a temperature of 20 degrees Celsius, which is then transmitted to the control module 500. The control module 500 controls the heating unit 410 to generate heat until the temperature value detected by the temperature detection unit 310 is between 30 degrees Celsius and 38 degrees Celsius. The control module 500 can control the heating unit 410 to stop generating heat.

[0056] Similarly, the control module 500 is connected to the humidity detection unit 320. The control module 500 can control the humidity detection unit 320 to detect the humidity of the housing 100, and the humidity information generated by the humidity detection unit 320 is transmitted to the control module 500. Furthermore, the control module 500 is also connected to the humidification unit 420. The control module 500 can control the humidification unit 420 to generate water vapor to adjust the humidity. Specifically, based on the acquired humidity information, the control module 500 can control the humidification unit 420 to generate an appropriate amount of water vapor, thereby adjusting the internal humidity of the housing 100 to a level suitable for the fermentation of the tobacco leaves 20. For example, if the relative humidity suitable for the fermentation of the tobacco leaves 20 is between 35% and 40%, the control module 500 controls the humidity detection unit 320 to detect a relative humidity of 20%, and transmits this humidity information to the control module 500. The control module 500 controls the humidification unit 420 to generate water vapor until the relative humidity detected by the humidity detection unit 320 is between 35% and 40%. At this point, the control module 500 controls the humidification unit 420 to stop generating water vapor. In other words, the control module 500 adjusts the temperature and humidity within the housing 100 based on the actual detected temperature and humidity, thereby more accurately maintaining the temperature and humidity within the housing 100 and ensuring the accuracy of the fermentation of the tobacco leaves 20.

[0057] The control module 500 is also connected to the position adjustment unit 430. While regulating the heating unit 410 and the humidifying unit 420, the control module 500 also adjusts the position of the position adjustment unit 430, thereby achieving adjustment of the position of the tobacco leaves 20 during the temperature and / or humidity adjustment process, thereby ensuring a better fermentation effect of the tobacco leaves 20. Specifically, when adjusting the temperature and humidity in the box 100 through the heating unit 410 or the humidifying unit 420, it is necessary to continuously adjust the position of the tobacco leaves 20 to avoid the tobacco leaves 20 being too wet or too dry. Compared with manually adjusting the position of the tobacco leaves 20, the embodiment of the present invention adjusts the position adjustment module 430 through the control module 500 to drive the position change of the tobacco leaves 20, that is, the position of the tobacco leaves 20 can be adaptively adjusted according to the current environment, reducing manual costs. Therefore, the tobacco fermentation box 10 provided in the embodiment of the present invention can be combined with the detection module 300 and the adjustment module 400 to monitor the environmental conditions and the status of the tobacco leaves 20 in real time, and can adaptively adjust the position of the tobacco leaves 20 (i.e., turn the tobacco leaves over) in accordance with the current status, thereby eliminating the reliance on manual experience to adjust process parameters, and ensuring the optimization of the fermentation process of the tobacco leaves 20 and the stability of the product quality. Optionally, there are various ways to connect the control module 500 with the detection module 300 and the control module 500 with the adjustment module 400, which can be either a communication connection or an electrical connection. The embodiment of the present invention does not limit the specific connection method, and can be adaptively adjusted according to actual needs.

[0058] In summary, an embodiment of the present invention provides a tobacco fermentation box, in which a control module is respectively connected to a temperature detection unit, a humidity detection unit, a heating unit, a humidification unit and a position adjustment unit. The control module can control the detection module to detect temperature and humidity, and adjust the adjustment module according to the detected temperature information and humidity information to ensure that the environment inside the box is suitable for the fermentation of tobacco leaves, ensure the fermentation effect of tobacco leaves, and improve the production yield.

[0059] Figure 4 1 is a schematic diagram of a top view of the second tobacco fermentation box provided by an embodiment of the present invention. Figure 5 This is a schematic structural diagram of the second tobacco fermentation box provided by the embodiment of the present invention, with reference to Figure 4 and Figure 5As shown, the heating unit 410 includes a heater 411; the control module 500 is used to control the heater 411 to heat or not heat; the humidifying unit 420 includes a nozzle 422 and a conduit 421, the conduit 421 is arranged on one side of the tobacco placement plate 200; a plurality of nozzles 422 are located on the conduit 421, and the nozzles 422 face one side of the tobacco placement plate 200, and the first end of the conduit 421 is connected to a water source (not specifically shown in the figure); the control module 500 is connected to the nozzle 422, and the control module 500 is used to control the nozzle 422 to open or close. or closed; when the temperature information obtained by the control module 500 is less than the first preset temperature value, the control module 500 controls the heater 411 to heat; when the temperature information obtained by the control module 500 is greater than or equal to the first preset temperature value, the control module 500 controls the heater 411 not to heat; when the humidity information obtained by the control module 500 is less than the first preset humidity value, the control module 500 controls the nozzle 422 to open; when the humidity information obtained by the control module 500 is greater than or equal to the first preset humidity value, the control module 500 controls the nozzle 422 to close.

[0060] For further reference, Figure 4 and Figure 5 As shown, the heating unit 410 includes a heater 411. The heater 411 can be an electric heater, such as a PTC ceramic heating element or a resistance wire. The specific type of heater 411 can be adaptively adjusted according to needs, and the embodiment of the present invention does not specifically limit this. Specifically, the control module 500 is connected to the heater 411. The control module 500 controls the heater 411 to heat to increase the ambient temperature in the box 100. If the ambient temperature in the box 100 meets the fermentation temperature of the tobacco leaves 20, the control module 500 controls the heater 411 to not heat. Specifically, the control module 500 adjusts the temperature of the heater 411 more controllable and precise, facilitating the fine temperature control of the tobacco fermentation box 10. For example, the heater 411 is a PTC ceramic heating element. When the temperature control range set by the control module 500 is within the appropriate fermentation range (30°C-50°C), the PTC ceramic heating element can ensure that the temperature adjustment accuracy of the box 100 is ±0.5°C, ensuring that the temperature value of the box 100 is suitable for tobacco fermentation. The preset temperature range for different tobacco leaves 20 will be adaptively adjusted.

[0061] For further reference, Figure 4 and Figure 5As shown, the humidification unit 420 includes a nozzle 422 and a conduit 421, wherein a section of the conduit 421 is connected to a water source, and the nozzle 422 is arranged on the conduit 421. When the nozzle 422 is open, the liquid flowing in the conduit 421 will be ejected through the nozzle 422 to adjust the ambient humidity; when the nozzle 422 is closed, the liquid flowing in the conduit 421 will not be ejected through the nozzle 422, and the adjustment of the ambient humidity will stop. Specifically, the control module 500 is connected to the nozzle 422. The control module 500 controls the nozzle 422 to open to humidify and increase the ambient humidity in the box 100. If the ambient humidity in the box 100 meets the fermentation humidity of the tobacco leaves 20, the control module 500 controls the nozzle 422 to close. Furthermore, the nozzle 422 can spray toward one side of the tobacco leaf placement plate 200, so that the moisture content of the tobacco leaves 20 can be adjusted while adjusting the ambient humidity in the box 100. Furthermore, the humidification unit 420 may include multiple nozzles 422, and the multiple nozzles 422 are located on the duct 421, which can ensure that the humidity adjustment of the box 100 is more efficient, and can also ensure that the tobacco leaves 20 on the tobacco leaf placement plate 200 can receive balanced humidity changes, thereby ensuring the fermentation effect on the tobacco leaves 20.

[0062] Exemplarily, the control module 500 compares the temperature information obtained by the temperature detection unit 310 with a first preset temperature value. The first preset temperature value can be understood as a temperature value pre-set in the control module 500, which is a temperature value suitable for fermentation in the environment in which the tobacco leaves 20 are located. Specifically, when the temperature information obtained by the control module 500 is less than the first preset temperature value, it proves that the internal temperature of the current box 100 is low and unsuitable for fermentation of the tobacco leaves 20. Therefore, the control module 500 controls the heater 411 to heat. At the same time, the control module 500 can synchronously control the position adjustment unit 430 to adjust the position to avoid uneven heating of the tobacco leaves 20 on the tobacco leaf placement plate 200 during the heating process of the heater 411, thereby ensuring the fermentation effect of the tobacco leaves 20. Specifically, when the temperature information obtained by the control module 500 is greater than or equal to the first preset temperature value, it proves that the current internal temperature of the box 100 can ensure the fermentation of the tobacco leaves 20. Therefore, the control module 500 no longer needs to control the heater 411 to heat. In consideration of saving resources and avoiding excessively high ambient temperature, the control module 500 controls the heater 411 not to heat.

[0063] Exemplarily, the control module 500 compares the humidity information obtained by the humidity detection unit 320 with a first preset humidity value. The first preset humidity value can be understood as a humidity value pre-set in the control module 500 and is a humidity value suitable for fermentation in the environment of the tobacco leaves 20. Specifically, when the humidity information obtained by the control module 500 is less than the first preset humidity value, it proves that the internal humidity of the current box 100 is low and unsuitable for fermentation of the tobacco leaves 20. Therefore, the control module 500 controls the nozzle 422 to open and spray water to increase moisture. At the same time, the control module 500 can also synchronously control the position adjustment unit 430 to adjust its position to avoid uneven moisture distribution among the tobacco leaves 20 on the tobacco leaf placement plate 200 during the water spraying process of the nozzle 422, thereby ensuring the fermentation effect of the tobacco leaves 20. Specifically, when the water vapor information obtained by the control module 500 is greater than or equal to the first preset water vapor value, it proves that the internal humidity of the current box 100 can ensure the fermentation of the tobacco leaves 20. Therefore, the control module 500 no longer needs to control the nozzle 422 to open to release water vapor. In consideration of saving resources and avoiding excessively high ambient humidity, the control module 500 controls the nozzle 422 to close.

[0064] Continue to refer Figure 4 and Figure 5 As shown, the tobacco fermentation box 10 also includes a tobacco moisture content detection unit 600, which is connected to the control module 500; the tobacco moisture content detection unit 600 is located on one side of the tobacco placement plate 200; the tobacco moisture content detection unit 600 is used to detect the moisture content of the tobacco 20.

[0065] For further reference, Figure 4 and Figure 5 As shown, the tobacco fermentation box 10 further includes a tobacco moisture content detection unit 600, which is used to detect the moisture content of the tobacco leaves 20. The tobacco moisture content detection unit 600 can be a near infrared spectrometer. Figure 4 As shown, the tobacco moisture content detection unit 600 is located on one side of the tobacco placement plate 200, thereby ensuring that the distance between the tobacco moisture content detection unit 600 and the tobacco leaves 20 is small, so that the moisture content of the tobacco leaves 20 on the tobacco placement plate 200 can be better effectively detected.

[0066] Furthermore, the tobacco moisture content detection unit 600 is connected to the control module 500. The control module 500 can combine the detection results of the tobacco moisture content detection unit 600 with the humidity information from the humidity detection unit 320 to adjust the humidification unit 420. In other words, the control module 500 can adjust the humidity within the housing 100 based on the ambient humidity and the moisture content of the tobacco leaves 20, thereby ensuring that the control module 500's regulation of the humidification unit 420 is more reliable.

[0067] Furthermore, when the control module 500 pre-sets the moisture content of tobacco leaves 20 suitable for fermentation to be between 25-28%, the control module 500 can control the humidification unit 420 to adjust the humidity, that is, control the nozzle 422 to spray water when the moisture content falls below the threshold. By configuring an atomizing nozzle array and combining it with the tobacco moisture content detection unit 600, the moisture content of the tobacco leaves 20 is monitored in real time, and dynamic spray replenishment is performed. The droplet size of the nozzle 422 can be ≤50μm, and a multi-point spraying or penetration method is used to ensure that the water is evenly distributed throughout the chamber.

[0068] Optionally, a temperature detection device, a humidity detection device and a tobacco leaf moisture content detection device can be set near each tobacco leaf placement board to detect the status of the tobacco leaves in real time. The temperature and humidity curve can be dynamically adjusted to ensure that the tobacco leaf moisture content is suitable for tobacco leaf fermentation, thereby improving fermentation efficiency and shortening the fermentation cycle.

[0069] Continue to refer Figure 4 and Figure 5 As shown, the temperature detection unit 310 and the humidity detection unit 320 are integrated.

[0070] For further reference, Figure 4 and Figure 5 As shown, the integrated design of the temperature detection unit 310 and the humidity detection unit 320 facilitates the miniaturization of the detection module 300. This frees up more space within the housing 100 for placement of other detection or adjustment components, ensuring the fermentation efficiency of the tobacco leaves 20. Furthermore, the miniaturization of the detection module 300 provides more space for the tobacco leaves 20, allowing more tobacco leaves 20 to be placed within the housing 100, thereby improving the fermentation efficiency of the tobacco leaves 20.

[0071] Continue to refer Figure 4 and Figure 5 As shown, the position adjustment unit 430 includes a flipping mechanism 431 and a bracket 432; the tobacco placement plate 200 is fixed on the bracket 432, and the end of the bracket 432 is mechanically connected to the flipping mechanism 431, and the rotation of the flipping mechanism 431 drives the bracket 432 to rotate; the flipping mechanism 431 is connected to the control module 500, and the control module 500 controls the rotation of the flipping mechanism 431 and adjusts the position of the tobacco placement plate 200.

[0072] Specifically, refer to Figure 4 and Figure 5As shown, the position adjustment unit 430 includes a flipping mechanism 431 and a bracket 432. The flipping mechanism 431 is provided with a chain 431a, which is driven by a chain motor 431b, thereby rotating the flipping mechanism 431. The flipping mechanism 431 is connected to the bracket 432. When the flipping mechanism 431 rotates, the bracket 432 also rotates. Furthermore, the tobacco placement plate 200 is fixed to the bracket 432. The position adjustment unit 430 rotates the flipping mechanism 431, thereby rotating the bracket 432 and the tobacco placement plate 200. This changes the position of the tobacco leaves 20, thereby turning the tobacco leaves 20.

[0073] Continue to refer Figure 4 and Figure 5 As shown, the position adjustment unit 430 includes a telescopic unit 433; the telescopic unit 433 is located between the bracket 432 and the tobacco placement plate 200, and the telescopic unit 433 adjusts the distance between the bracket 432 and the tobacco placement plate 200; the telescopic unit 433 is connected to the control module 500, and the control module 500 controls the telescopic length of the telescopic unit 433 to adjust the position of the tobacco placement plate 200.

[0074] For further reference, Figure 4 and Figure 5 As shown, the position adjustment unit 430 further includes a telescopic unit 433, which is disposed between the bracket 432 and the tobacco placement plate 200. The telescopic unit 433 can be extended and retracted. Therefore, the control module 500 adjusts the position of the tobacco placement plate 200 relative to the bracket 432 by controlling the extension length of the telescopic unit 433. By adding the telescopic unit 433, the position adjustment of the tobacco placement plate 200 relative to the bracket 432 can be diversified, which can better adjust the position of the tobacco leaves 20 and ensure the fermentation uniformity of the tobacco leaves 20.

[0075] Continue to refer Figure 4 and Figure 5 As shown, the box body 100 also includes an air inlet 100a and an air outlet 100b. The control module 500 is connected to the air inlet 100a, and the control module 500 controls the opening or closing of the air inlet 100a; the control module 500 is connected to the air outlet 100b, and the control module 500 controls the opening or closing of the air outlet 100b.

[0076] For further reference, Figure 4 and Figure 5As shown, the housing 100 further includes an air inlet 100a and an air outlet 100b, and the control module 500 can control the opening or closing of the air inlet 100a, as well as the opening or closing of the air outlet 100b. By regulating the air inlet 100a and the air outlet 100b, the air pressure and air content of the housing 100 can be adjusted, thereby ensuring that the tobacco leaves 20 are in a suitable fermentation environment and ensuring the fermentation effect of the tobacco leaves 20.

[0077] Continue to refer Figure 4 As shown, the box body 100 includes a heat-insulating layer 100 c , and the heat-insulating layer 100 c is located inside the box body 100 .

[0078] For further reference, Figure 4 As shown, the housing 100 includes an insulation layer 100c. This insulation layer 100c minimizes fluctuations in the temperature and humidity within the housing 100. In other words, after the control module 500 adjusts the temperature and humidity within the housing 100, the conditions are optimal for the fermentation of the tobacco leaves 20. The insulation layer 100c maintains the environment within the housing 100 for an extended period, ensuring optimal fermentation of the tobacco leaves 20.

[0079] Based on the same invention communication, the embodiment of the present invention also provides a method for detecting the air tightness of the tofu drying machine drum. Figure 6 This is a flow chart of a control method for a first tobacco fermentation box according to an embodiment of the present invention, with reference to Figure 6 As shown, the control method of the tobacco fermentation box includes:

[0080] S110 , controlling the temperature detection unit to detect the temperature information inside the box.

[0081] The tobacco fermentation box provided in the embodiments of the present invention is used to ferment tobacco leaves placed within the box. After fermentation, the tobacco leaves can be free of defects and used in cigarette production. Specifically, the tobacco fermentation box includes a box body and a tobacco placement plate placed within the box body. The tobacco placement plate is used to place tobacco leaves, and the box body provides the necessary environment for tobacco fermentation. Furthermore, multiple tobacco placement plates can be installed within a single box body, enabling simultaneous fermentation of a large number of tobacco leaves.

[0082] Furthermore, the tobacco fermentation box includes a detection module, which is located on a side wall of the box. The detection module can detect environmental factors within the box, thereby ensuring that the tobacco leaves are in a state conducive to fermentation. Optionally, the specific side wall of the box where the detection module is located can be adaptively adjusted according to actual needs, and this embodiment of the present invention does not specifically limit this.

[0083] Specifically, the detection module includes a temperature detection unit, wherein the temperature detection unit is used to detect the temperature information inside the box, and then determine whether it is convenient for tobacco leaves to ferment at present based on the temperature information. Optionally, the box may include multiple temperature detection units, and the number of temperature detection units set corresponds to the number of tobacco placement plates set. Furthermore, the tobacco fermentation box also includes a control module, which is connected to the temperature detection unit. It can be understood that the control module can control the temperature detection unit for detection and can obtain the temperature information detected by the temperature detection unit. Optionally, the control module can be a programmable logic controller (PLC), which controls various types of mechanical equipment or production processes through digital or analog input and output.

[0084] S120: Control the humidity detection unit to detect humidity information inside the box.

[0085] Specifically, the detection module includes a humidity detection unit, which is used to detect humidity information within the box and, based on this humidity information, determine whether the tobacco leaves are currently suitable for fermentation. Optionally, the box may include multiple humidity detection units, with the number of humidity detection units corresponding to the number of tobacco placement plates. Furthermore, the control module is also connected to the humidity detection unit, so that the control module can control the humidity detection unit to perform detection and obtain humidity information detected by the humidity detection unit.

[0086] S130 , acquiring temperature information and humidity information, and regulating the heat of the heating unit, regulating the water vapor of the humidifying unit, and regulating the position of the position adjustment unit according to the temperature information and humidity information.

[0087] Furthermore, the tobacco fermentation box also includes a regulation module that can adjust the environmental factors (such as humidity and temperature) inside the box and adjust the placement of the tobacco leaves to ensure that the tobacco leaves are in the best fermentation state. Specifically, the regulation module includes a heating unit and a humidifying unit, wherein the heating unit and the humidifying unit are arranged inside the box, and the heating unit and the humidifying unit are arranged on the top side wall of the box. The specific location of the heating unit and the humidifying unit can be adaptively adjusted according to actual process requirements. The heating unit can generate heat and adjust the temperature inside the box according to the heat generated by the heating unit; the humidifying unit can generate water vapor and adjust the humidity inside the box according to the water vapor generated by the humidifying unit. By regulating the heating unit and the humidifying unit, the temperature and humidity inside the box can be ensured to be at a temperature and humidity suitable for tobacco fermentation, ensuring the fermentation effect of the tobacco leaves. Optionally, the number of heating units and humidifying units set in the box can be adaptively adjusted, and the number of heating units and humidifying units set can also correspond to the number of tobacco placement plates set.

[0088] Furthermore, the adjustment module also includes a position adjustment unit, which is located inside the box and is connected to the tobacco leaf placement plate. When the position adjustment unit is in position adjustment, the position adjustment unit will drive the tobacco leaf placement plate to adjust its position. That is, the position adjustment unit can drive the position adjustment of the tobacco leaf placement plate according to the adjustment of its own position, thereby realizing the adjustment of the position of the tobacco leaves. By changing the position or angle of the position adjustment unit, the tobacco leaves can be driven to change their position or angle, thereby ensuring the multi-angle and multi-dimensional fermentation of the tobacco leaves and ensuring the fermentation conditions of the tobacco leaves. For example, when the heating unit and the humidifying unit adjust the temperature and humidity, the tobacco leaves can be driven to change their angles through the position adjustment unit, which can ensure the fermentation uniformity of the tobacco leaves and the fermentation effect of the tobacco leaves.

[0089] Specifically, the control module is connected to a temperature detection unit. The control module can control the temperature detection unit to detect the temperature of the box, and the temperature information generated by the temperature detection module is transmitted to the control module. Furthermore, the control module is also connected to a heating unit. The control module can control the heating unit to generate heat. Specifically, based on the temperature information obtained, the control module can control the heating unit to generate an appropriate amount of heat, thereby adjusting the internal ambient temperature of the box to a temperature suitable for tobacco leaf fermentation. For example, if the temperature suitable for tobacco leaf fermentation is 30 to 38 degrees Celsius, the control module controls the temperature detection unit to detect a temperature of 20 degrees Celsius, and transmits this temperature information to the control module. The control module controls the heating unit to generate heat until the temperature detected by the temperature detection unit is between 30 and 38 degrees Celsius, at which point the control module can control the heating unit to stop generating heat. Similarly, the control module is connected to a humidity detection unit. The control module can control the humidity detection unit to detect the humidity of the box, and the humidity information generated by the humidity detection unit is transmitted to the control module. Furthermore, the control module is also connected to a humidification unit, which can control the humidification unit to generate water vapor to adjust the humidity. Specifically, based on the acquired humidity information, the control module 500 can control the humidification unit to generate an appropriate amount of water vapor, thereby adjusting the internal humidity of the chamber to a level suitable for tobacco leaf fermentation. For example, if the relative humidity suitable for tobacco leaf fermentation is between 35% and 40%, the control module controls the humidity detection unit to detect humidity. The humidity detection unit detects a relative humidity of 20% and transmits this humidity information to the control module. The control module controls the humidification unit to generate water vapor until the relative humidity detected by the humidity detection unit 0 is between 35% and 40%, at which point the control module controls the humidification unit to stop generating water vapor. The control module is also connected to a position adjustment unit. While controlling the heating unit and humidification unit, the control module also adjusts the position of the position adjustment unit. This allows the position of the tobacco leaves to be adjusted while adjusting the temperature and / or humidity, ensuring a more effective fermentation.

[0090] In summary, the embodiment of the present invention provides a control method for a tobacco fermentation box, in which the control module adaptively adjusts the adjustment module through the acquired temperature information and humidity, ensuring that the tobacco leaves in the box are in a suitable fermentation atmosphere, ensuring the fermentation effect of the tobacco leaves, and improving the production yield.

[0091] Optional, Figure 7 This is a flow chart of a second method for controlling a tobacco fermentation box according to an embodiment of the present invention. Figure 7 As shown, the control method of the tobacco fermentation box also includes:

[0092] S210 , controlling the temperature detection unit to detect the temperature information inside the box.

[0093] S220: Control the humidity detection unit to detect humidity information inside the box.

[0094] S230: Determine whether the temperature information is less than a first preset temperature value.

[0095] Specifically, the heating unit includes a heater, which can be an electric heater, such as a PTC ceramic heating element or a resistance wire. The specific type of heater can be adjusted according to needs and is not specifically limited in the embodiments of the present invention. Specifically, a control module is connected to the heater, and the control module controls the heater to heat the box to increase the ambient temperature inside the box. If the ambient temperature inside the box meets the fermentation temperature of the tobacco leaves, the control module controls the heater to not heat.

[0096] Furthermore, the humidification unit includes a nozzle and a conduit, wherein a section of the conduit is connected to a water source, and the nozzle is arranged on the conduit. When the nozzle is opened, the liquid flowing in the conduit will be ejected through the nozzle to adjust the ambient humidity; when the nozzle is closed, the liquid flowing in the conduit will not be ejected through the nozzle, and the adjustment of the ambient humidity will stop. Specifically, the control module is connected to the nozzle, and the control module humidifies by controlling the nozzle to open to increase the ambient humidity in the box. If the ambient humidity in the box meets the fermentation humidity of the tobacco leaves, the control module controls the nozzle to close. Furthermore, the nozzle can be sprayed toward one side of the tobacco leaf placement plate, so that the moisture content of the tobacco leaves can be adjusted while adjusting the ambient humidity in the box. Furthermore, the humidification unit can include multiple nozzles, and multiple nozzles are located on the conduit, which can ensure that the humidity adjustment of the box is more efficient, and can also ensure that the tobacco leaves on the tobacco leaf placement plate can receive balanced humidity changes, thereby ensuring the fermentation effect of the tobacco leaves.

[0097] Specifically, the control module compares the temperature information obtained by the temperature detection unit with the first preset temperature value. The first preset temperature value can be understood as a temperature value pre-set in the control module. The first preset temperature value is a temperature value suitable for fermentation in the environment where the tobacco leaves are located.

[0098] S240: When the temperature information is less than a first preset temperature value, control the heater to heat and regulate the position adjustment unit.

[0099] Specifically, when the temperature information obtained by the control module is less than a first preset temperature value, it indicates that the current internal temperature of the box is low and unsuitable for tobacco fermentation. Therefore, the control module controls the heater to heat. Simultaneously, the control module can also control the position adjustment unit to adjust the position to avoid uneven heating of the tobacco leaves on the tobacco plate during the heating process, thereby ensuring the fermentation effect of the tobacco leaves.

[0100] S250: When the temperature information is greater than or equal to a first preset temperature value, control the heater not to heat.

[0101] Specifically, when the temperature information obtained by the control module is greater than or equal to the first preset temperature value, it proves that the current internal temperature of the box can ensure the fermentation of the tobacco leaves. Therefore, the control module no longer needs to control the heater to heat. Considering saving resources and avoiding excessively high ambient temperature, the control module 500 controls the heater not to heat.

[0102] S260: Determine whether the humidity information is less than a first preset humidity value.

[0103] The control module 500 compares the humidity information obtained by the humidity detection unit with a first preset humidity value. The first preset humidity value can be understood as a humidity value pre-set in the control module. The first preset humidity value is a humidity value suitable for fermentation in the environment where the tobacco leaves are located.

[0104] Optionally, the temperature information may be determined first and then the humidity information, or the humidity information may be determined first and then the temperature information.

[0105] S270: When the humidity information is less than a first preset humidity value, control the nozzle to open and regulate the position adjustment unit.

[0106] Specifically, when the humidity information obtained by the control module is less than a first preset humidity value, indicating that the current internal humidity of the chamber is low and unsuitable for tobacco fermentation, the control module controls the nozzle to open and spray water to increase moisture. Simultaneously, the control module can also synchronously control the position adjustment unit to adjust its position to avoid uneven moisture distribution on the tobacco leaves on the tobacco plate during the nozzle spraying process, thereby ensuring the fermentation effect of the tobacco leaves.

[0107] S280: When the humidity information is greater than or equal to a first preset humidity value, control the nozzle to close.

[0108] When the water vapor information obtained by the control module is greater than or equal to the first preset water vapor value, it proves that the internal humidity of the current box can ensure the fermentation of tobacco leaves. Therefore, the control module no longer needs to control the nozzle to open to release water vapor. In consideration of saving resources and avoiding excessively high ambient humidity, the control module controls the nozzle to close.
