It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 7, a printer for high humidity environment according to a preferred embodiment of the present invention includes a housing 10, a paper compartment box 40, a first upper cover 20, a second upper cover 30, a sealing assembly 50 and a drying device 60, wherein the paper compartment box 40 is disposed in the housing 10 and located below the first upper cover 20, the first upper cover 20 and the second upper cover 30 are disposed side by side, the first upper cover 20 is rotatably connected to one side of an upper end of the housing 10, and the second upper cover 30 is connected to the other side of the upper end of the housing 10; the sealing assembly 50 is used for isolating water vapor in the air from entering the interior of the housing 10, and the drying device 60 is used for absorbing water vapor (source and humid air) entering the housing 10.

The sealing assembly 50 includes a waterproof ring 51 and a waterproof cover plate 52, the waterproof ring 51 is disposed on the housing 10 and surrounds the first upper cover 20 and the second upper cover 30, and the waterproof cover plate 52 is disposed between the first upper cover 20 and the second upper cover 30.

The drying device 60 is arranged at the bottom of the shell 10, is positioned below the paper bin box 40, adopts an air conditioning principle and a condensation principle, and comprises an evaporator 61, a compressor 63 and a condenser 62, wherein the evaporator 61, the compressor 63 and the condenser 62 are sequentially connected through a capillary tube 64, and a refrigerant is arranged in the interior of the evaporator, the compressor 63 and the condenser 62; the evaporator 61 vaporizes a liquid refrigerant at normal temperature and high pressure to turn the refrigerant into a low-temperature gaseous refrigerant, and condenses water vapor in the air into water droplets; the compressor 63 compresses the low-temperature gaseous refrigerant into a high-temperature high-pressure gaseous refrigerant; the condenser 62 radiates heat from the high-temperature and high-pressure gas refrigerant to obtain a normal-temperature and high-pressure liquid refrigerant. Specifically, the evaporator 61 is disposed right below the bottom of the hopper box 40, and the compressor 63 and the condenser 62 are disposed outside the hopper box 40 and at the bottom of the casing 10.
