The storage device comprises a heat preservation
barrel and a heat preservation cover, a heat preservation cavity is formed in the heat preservation
barrel, a freezing rotary table is rotatably installed in the heat preservation cavity, and a plurality of
insertion grooves for the ice cotton swabs to be inserted are formed in the freezing rotary table in the circumferential direction at equal intervals; a driving mechanism for driving the freezing rotary table to rotate is arranged in the heat preservation
barrel, the control end of the driving mechanism is connected with a
control switch through a controller, an inserting rod is embedded in the heat preservation barrel below one inserting groove, and inserting holes communicated with the inserting grooves are formed in the bottom of the freezing rotary table in cooperation with the inserting rod. A
cotton swab outlet matched with the ice
cotton swab is formed in the position, corresponding to the inserting rod, of the heat preservation cover; a telescopic mechanism matched with the inserting rod is embedded in the bottom of the heat preservation barrel, an extension triggering
assembly matched with the telescopic mechanism is arranged on the driving mechanism, and a retraction triggering
assembly matched with the telescopic mechanism is arranged on the driving mechanism or the heat preservation barrel. The heat preservation effect can reach 8-10 hours, and it can be guaranteed that ice cotton swabs in the heat preservation barrel are in a relatively
sterile environment.
