The invention discloses an intelligent constant-temperature distribution box which comprises an outer sleeve (1), a box cover (2), a box body (3), a transparent film (4), touch and close fasteners (5), an inner container veneering (6), a temperature controller (7), an intelligent lock (8), a chip (9), a heating device (10), a temperature monitor (11), a magnetic stripe (12), an electronic advertising board (13), a hydrogen sulfide detector (14) and a storage battery. The heating device can supply heat through an external heating source, and can also carry out heating by being powered by the carried storage battery, and the constant temperature of the heating device (10) is controlled through the temperature controller (7). The heating device (10) comprises an electric heating device body and a hot water heating device body. The problems that in the prior art, a distribution box is unintelligent in temperature control, cannot achieve heating, is single in function, cannot play advertisements and is inconvenient to clean, and the freshness of distributed objects cannot be monitored constantly are solved. The technical effects that temperature control over the distribution box is intelligent, the functions are comprehensive, cleaning is convenient, and the freshness of the distributed objects can be conveniently monitored are achieved.
