Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 A box-type tobacco leaf rehumidification device includes a suspension assembly for suspending tobacco leaves side by side, and a box assembly for sealing the rehumidification of evaporated water vapor. A pipe assembly for controlling the flow direction of water vapor is installed on the box assembly, and the suspension assembly is installed in the box assembly.

[0025] In this embodiment: the box assembly includes a sealed box 101, a sealed door 105 is installed in front of the sealed box 101, the sealed door 105 and the sealed box 101 are hingedly connected, a water tank box 102 is arranged at the bottom of the sealed box 101, a heating plate 104 is installed at the bottom of the water tank box 102, and a barrier net 103 is installed on the top of the water tank box 102 to prevent tobacco leaves from falling into the water tank box 102. The barrier net 103 and the water tank box 102 are snap-connected, the sealed door 105 is closed, the heating plate 104 heats the water in the water tank box 102 to evaporate to form water vapor, and the water vapor passes through the barrier net 103 and fills the sealed box 101 to rehumidify the tobacco leaves;

[0026] In this embodiment: the suspension assembly includes two symmetrically arranged fixing frames 201, the fixing frames 201 are connected to the inner wall of the sealed box 101 with bolts, a number of limiting grooves 202 are evenly distributed on the fixing frames 201, and the limiting grooves 202 are U-shaped. A support rod 203 is installed between the fixing frames 201, and the tobacco leaves are hung on the support rod 203, and the support rod 203 is inserted into the limiting groove 202 of the fixing frames 201, so that the tobacco leaves are suspended in the sealed box 101;

[0027] In this embodiment: the pipeline assembly includes an intake pipe 301, an outlet pipe 304 and a return pipe 306, and the intake pipe 301, the outlet pipe 304 and the return pipe 306 are distributed in a T shape, and the intake pipe 301, the outlet pipe 304 and the return pipe 306 are welded together. An air collecting hood 303 is arranged at the front end of the intake pipe 301. The air collecting hood 303 is made of polypropylene material and is riveted together with the intake pipe 301. A cross-flow fan 302 is installed on the intake pipe 301, an outlet valve 305 is installed on the outlet pipe 304, and a return valve 307 is installed on the return pipe 306.
