[0040] A heat pump system 2 for controlling the temperature and humidity in the accommodating chamber 11; the heat pump system 2 is fixedly connected to the room body 1;

[0041] Lifting mechanism 3; the lifting mechanism 3 includes: a support seat 31, a rotating shaft 32, a winch 33, a driving motor 34, a hanging rack 35, and a cable 36;

[0042] The object hanging rack 35 is located at the upper part of the accommodating chamber 11; the support seat 31 is fixedly connected to the top of the house body 1, and the rotating shaft 32 is rotatably connected to the support seat 31; a worm gear 37 is also fixedly penetrated on the rotating shaft 32, and the output end of the driving motor 34 is transmission-connected to a worm 38 meshing with the worm gear 37; the capstan 33 is fixedly connected to the rotating shaft 32; one end of the cable 36 is fixedly connected to the capstan 33, and the other end passes through the house body 1 and is fixedly connected to the object hanging rack 35.

[0043] The rotating shaft 32 is driven to rotate by the driving motor 34, and the rotating shaft 32 drives the winch 33 to rotate to winch the cable, thereby lifting the hanging rack 35 up and down. The worker can move the hanging rack 35 downward to a suitable position according to the needs, so as to hang the tobacco leaves on the hanging rack 35. After hanging the tobacco leaves, the driving motor 34 is started, and the hanging rack 35 rises to the top of the accommodating chamber 11. There is no need to manually hang the rods with tobacco leaves one by one, which reduces the labor intensity of the workers and improves the work efficiency. The lifting mechanism 3 has a simple structure. Through the cooperation of the worm gear 37 and the worm 38, the rotation of the rotating shaft 32 can be controlled when the motor stops.

[0044] In some embodiments, there are multiple cables 36, and the multiple cables 36 are symmetrically distributed on both sides of the object hanging rack 35; there are two winches 33, and the two winches 33 are respectively fixed at both ends of the rotating shaft 32; the cables 36 on both sides of the object hanging rack 35 are respectively fixedly connected to the two winches 33 in a one-to-one correspondence. Multiple cables 36 can lift the object hanging rack 35 better and more stably.

[0045] Specifically, a fixed pulley is provided at the top of the accommodating chamber 11, and the cable 36 passes through the fixed pulley, which is located just above the connection point between the cable 36 and the object hanging rack 35, so as to ensure that the tension on the object hanging rack 35 is parallel to its own gravity, thereby avoiding the generation of a resultant force in the horizontal direction.

[0046] In some embodiments, the heat pump system 2 includes: a storage box 21 and a compressor 22, a condenser 23, an expansion valve 24, and an evaporator 25 connected in sequence; the outlet of the evaporator 25 is connected to the inlet of the compressor 22 to form a closed loop; the storage box 21 is fixedly connected to the outer surface of the house body 1; the compressor 22 is placed in the storage box 21, and the evaporator 25 has a first evaporation part 251 and a second evaporation part 252; the first evaporation part 251 is located in the storage box 21, and the second evaporation part 252 is located in the accommodating chamber 11; a collection tank 26 for collecting condensed water is provided below the second evaporation part 252. Compared with the baking method of burning coal and electricity, the use of the heat pump system 2 is more energy-saving and environmentally friendly. When the hot air flows through the second evaporation part 252, the temperature decreases, and the water vapor in the air condenses into water droplets, which adhere to the second evaporation part 252 and then fall into the collection tank 26, so as to achieve dehumidification of the air in the accommodating chamber 11.

[0047] Specifically, the outlet of the compressor 22 is connected to the condenser 23, the outlet of the condenser 23 is connected to the expansion valve 24, and the outlet of the expansion valve 24 is connected to the evaporator 25;

[0048] The housing 1 and the accommodating chamber 11 are roughly in the shape of a rectangular parallelepiped, and the condenser 23 is wound around the inner wall of the accommodating chamber 11 and is in the shape of a coil. The condenser 23 is wound around and fixed on the inner wall of the three accommodating chambers 11. This method allows the accommodating chamber 11 to be heated more evenly.

[0049] An air inlet and an air outlet are provided in the upper opening of the storage box 21, and a third fan 6 is fixedly connected to the air inlet. A first evaporation part 251 is arranged in the air outlet direction of the third fan 6, and the first evaporation part 251 is in a coil shape; the wind speed at this position is increased by the third fan 6, thereby improving the heat exchange efficiency of the first evaporation part 251. The first evaporation part 251 is in a coil shape; the heat exchange area at this position is increased, and the heat exchange efficiency is improved.

[0050] In some embodiments, the bottom of the collecting tank 26 is connected to a drain pipe 27, and the drain pipe 27 passes through the accommodating cavity 11 to the outside of the house 1, so as to facilitate the water in the collecting tank 26 to be discharged from the accommodating cavity 11.

The partition 4 can be provided to shorten the length of the crossbar for hanging tobacco leaves, thereby ensuring the bearing capacity of the crossbar. The first fan 41 will accelerate the air flow in the two spaces, so that the heat distribution is more uniform.

[0052] Specifically, there are two door bodies 12, and the two door bodies 12 are connected to two spaces respectively, which can facilitate workers to enter and exit each space.

[0053] There are also two lifting mechanisms 3, which are located above the two spaces in a one-to-one correspondence.

[0054] In some embodiments, the second evaporation part 252 is in a curved coil shape and is located at the air inlet of the first fan 41; the second evaporation part 252 is fixedly connected to the partition 4. Being located at the air inlet can increase the flow rate of air flowing through the second evaporation part 252 and improve the dehumidification capacity. The curved coil shape of the second evaporation part 252 increases the contact area with the air and also improves the dehumidification capacity.

[0055] In some embodiments, a second fan 13 is disposed on the inner wall of the accommodating chamber 11, and the wind direction of the second fan 13 is perpendicular to the wind direction of the first fan 41. This can increase the convection of air in the accommodating chamber 11 and facilitate the diffusion and distribution of heat.

[0056] Specifically, there are multiple first fans 41, which are divided into two groups and distributed on both sides of the partition 4, and the wind directions of the two groups of fans are opposite. This arrangement can cause the air in the accommodating cavity 11 to form a vortex, which is convenient for the uniform diffusion and distribution of heat energy.

[0057] Specifically, the number of the first fans 41 is multiple, and they are divided into two groups and respectively distributed in two spaces separated by the partition 4; the wind energy forms a circulating flow in the accommodating cavity 11

[0058] In some embodiments, the partition plate 4 is provided with a limit groove 42; the object hanging rack 35 is provided with a clamping block clamped in the limit groove 42, and the clamping block is slidably connected to the limit groove 42. The limit groove 42 can limit the movement of the object hanging rack 35 in the horizontal direction to ensure the safety of the object hanging rack 35.

[0059] In some embodiments, a first crossbar 43 is fixedly provided on the partition 4; a second crossbar 14 is fixedly provided on the inner wall of the accommodating cavity 11, and the first crossbar 43 and the second crossbar 14 are at the same level and parallel to each other. Providing the crossbars can facilitate the placement of the hanging rod, and the first crossbar 43 and the second crossbar 14 can limit the hanging rod to a horizontal plane, which is convenient for hanging tobacco leaves.

[0060] Specifically, there are two first cross bars 43 and two second cross bars 14, and the two first cross bars 43 are distributed in parallel on the partition 4; this arrangement can divide the hung tobacco leaves into three layers in total, so that the tobacco leaves are evenly distributed in the accommodating cavity 11, and the first cross bar 43 and the second cross bar 14 are provided with a plurality of slots arranged at equal intervals, and a hanging rod is clamped on the slot, and the tobacco leaves are hung on the hanging rod. The slot can clamp the hanging rod to prevent the hanging rod from slipping.

[0061] In some embodiments, a top cover 5 is fixedly provided on the top of the house body 1, and the lifting mechanism 3 is located below the top cover 5. The top cover 5 can protect the lifting mechanism 3 from wind and rain, thereby increasing the service life of the lifting mechanism 3.

[0062] Specifically, it also includes a processor, a temperature sensor, and a humidity sensor, the temperature sensor and the humidity sensor are electrically connected to the processor, and the first fan 41, the second fan 13, and the compressor 22 are electrically connected to the processor. The processor adjusts the power of the fan and the power of the heat pump according to the temperature and humidity in the accommodating chamber 11, thereby realizing automatic control of the temperature and humidity parameters of the tobacco curing room.

[0063] Finally, it should be noted that although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model.
