[0062] In one embodiment, the air regulating assembly 3 further includes a driving member 33 , which is connected to the air regulating plate 32 and the baking chamber 11 and is used to drive the air regulating plate 32 to rotate.

[0063] By controlling the driving member 33, the angle of the air regulating plate 32 can be adjusted, thereby adjusting the temperature and humidity of each area in the baking chamber, so that the temperature of the tobacco leaves is more uniform.

[0064] It should be understood that the driving member 33 can be a direct drive motor, a combination of a motor and a reducer, a combination of a motor and a belt transmission assembly, a combination of a motor and a gear transmission assembly, etc.

[0066] In one embodiment, the circulating air component 4 further includes a dehumidification component 42, and the dehumidification component 42 is arranged between the air inlet end of the fan 41 and the baking chamber.

[0067] During the baking process of tobacco leaves, water vapor will be formed, which will increase the humidity in the baking room 11. However, excessive humidity will affect the quality of tobacco leaves. Therefore, in the present embodiment, a dehumidifier 42 is provided to dehumidify the circulating air to control the humidity in the air, thereby improving the quality and taste of tobacco leaves. By removing moisture, it helps to maintain a dry environment in the baking chamber, which is beneficial to the preservation and subsequent processing of tobacco leaves.

[0069] In one embodiment, the baking room assembly 1 further includes a grille plate 12 , which is disposed above the air regulating plate 32 and is connected to the baking room 11 .

[0070] By providing the grille plate 12, the bottom of the baking room 11 can form a supporting structure, so that workers or tools can move in the baking room 11 with the support of the grille plate 12, and the grille plate 12 will not hinder the passage of circulating air at the bottom.

[0071] In one embodiment, one side of the baking room 11 is open, and the baking room assembly 1 further includes two closed doors 13, which are arranged relative to the open end of the baking room 11 and are rotatably connected to the baking room 11. The two closed doors 13 are arranged on both sides of the opening of the baking room 11.

[0072] By setting the opening, tobacco leaves can enter and exit the curing room 11 through the opening side of the curing room 11; the design of the two closed doors 13 enables the opening of the curing room 11 to obtain a better sealing effect, reduce heat loss, and improve curing efficiency. The closed door 13 can be rotatably connected to the curing room 11, which is convenient for the operator to open and close; the tobacco curing device of this embodiment further improves the curing effect and production efficiency by improving the design of the closed door 13, while reducing energy consumption and cost.

[0073] In one embodiment, the baking room assembly 1 further includes two stepping ramps 14, which are spaced apart at the opening side of the baking room 11, and one side of the stepping ramp 14 is a guiding slope, which gradually rises in a direction close to the baking room 11.

[0074] The design of the ramp 14 makes it more convenient and safe for the operator to enter the curing room 11. Since there is a certain height difference between the grille plate 12 of the curing room 11 and the ground, the guiding slope can play a good transition role; the design of the guiding slope makes it easier for the operator to carry the tobacco leaves into the curing room 11, reducing labor intensity and improving work efficiency.

[0075] In one of the embodiments, the air regulating component 3 also includes a second air equalizing plate 34, which is built into the baking cavity and combined with the top of the baking cavity to form a second air equalizing cavity. The second air equalizing plate 34 is provided with a plurality of second air equalizing holes, which are connected to the baking cavity and the second air equalizing cavity; the air inlet end of the fan 41 is connected to the second air equalizing cavity, and is connected to the baking cavity through the second air equalizing cavity.

[0076] By providing the second air equalizing plate 34, the air in the baking chamber can evenly enter the second air equalizing chamber, thereby avoiding uneven air flow in the baking room 11; this is beneficial to improving the baking effect and allowing the tobacco leaves to be baked more evenly.

[0077] In one embodiment, the baking room assembly 1 also includes multiple support members 15 and multiple fixing members 16. The multiple support members 15 are parallel to each other and are spaced apart and built into the baking cavity. The support members 15 include at least two vertical support rods 151, at least one horizontal support rod 152 and multiple limit blocks 153. At least two vertical support rods 151 are parallel to each other and spaced apart. The vertical support rod 151 is connected to the baking room 11. At least one horizontal support rod 152 connects at least two vertical support rods 151. Multiple limit blocks 153 are spaced apart on the horizontal support rod 152. A limit groove 153a is provided on the top of the limit block 153. The fixing member 16 includes a fixing rod 161. The two ends of the fixing rod 161 are respectively slidably inserted into the limit grooves 153a of the limit blocks 153 of two adjacent support members 15.

[0078] The tobacco leaves are fixed on the fixing rod 161, and then the two ends of the fixing rod 161 are respectively inserted into the limiting grooves 153a of the limiting blocks 153 of the two adjacent support members 15. The design of the support members 15 enables the tobacco leaves in the curing room 11 to be stably supported, preventing the tobacco leaves from piling up or deforming during the curing process, thereby affecting the curing effect; the two ends of the fixing rod 161 are slidably inserted into the limiting grooves 153a of the limiting blocks 153 of the two adjacent support members 15, so that the operator can fix and adjust the tobacco leaves conveniently and improve work efficiency.

[0079] In one embodiment, the limiting groove 153 a is triangular in shape, and the cross-sectional dimension of the limiting groove 153 a gradually decreases along a direction approaching the transverse support rod 152 .

[0080] The design of the triangular limiting groove 153a enables the fixing rod 161 to be automatically positioned when inserted into the limiting groove 153a, thereby improving the stability and reliability of the fixing rod 161, thereby better fixing the tobacco leaves; the design of the triangular limiting groove 153a also helps to prevent the fixing rod 161 from falling off due to vibration during the baking process, thereby ensuring the stability of the tobacco leaves in the baking room 11.

[0081] In one of the embodiments, both ends of the fixing rod 161 are provided with sliding grooves; the fixing member 16 also includes two sliding blocks 162, two limit bars 163 and two elastic parts 164, the two sliding blocks 162 are respectively slidably arranged in the two sliding grooves, the two limit bars 163 are respectively connected to the sliding blocks 162, the elastic parts 164 correspond to the sliding blocks 162 one by one, and the elastic parts 164 connect the sliding blocks 162 and the fixing rod 161, so as to provide elastic force for the limit bars 163 to elastically abut against the limit blocks 153.

[0082] By providing the sliding block 162, the limiting strip 163 and the elastic portion 164, the elastic portion 164 can push the sliding block 162 to move, so that the limiting strip 163 abuts against the limiting block 153. The existence of the two limiting strips 163 can limit the axial movement of the fixing rod 161 relative to the limiting block 153, thereby preventing the fixing rod 161 from sliding axially when the gas flows in the baking room 11, causing the fixing rod 161 to fall off from the limiting groove 153a of the limiting groove 153a.

[0083] It should be understood that the elastic portion 164 can be a spring, an elastic strip, an elastic block, etc.
