The invention discloses a cold and hot circulation device which comprises a box body, an isolation barrier, a heating assembly, a refrigeration assembly, an air blowing assembly, a driving assembly and a controller. The isolation barrier is movably arranged in the box body and divides the interior of the box body into a first cavity and a second cavity; the air blowing assembly is used for exhausting air in the box body out of the box body; the driving assembly drives the isolation barrier to move; when the isolation barrier moves to a first position, the heating assembly only heats air in thefirst cavity, and the air blowing assembly only communicates with the first cavity; and when the isolation barrier moves to the second position, the refrigeration assembly only refrigerates air in the first cavity, and the air blowing assembly only communicates with the first cavity. Due to the fact that in the process, the air in the first cavity is directly exhausted out of the box body throughthe air blowing assembly,
