The invention belongs to the technical field of thermogravimetric testing, and particularly relates to a thermogravimetric analysis device and a using method thereof.The thermogravimetric analysis device comprises a furnace body, a carrying assembly, a heating chamber, a bypass gas circuit and a control unit, a heating cavity for heating a to-be-tested sample is formed in the furnace body, and the carrying assembly is used for containing a crucible loaded with the to-be-tested sample; the heating chamber is used for heating and cleaning the crucible; and the bypass gas path is used for blowing the crucible on the carrying assembly into the heating chamber. In the thermogravimetric analysis process, a crucible filled with a sample to be detected is placed on the carrying assembly, the heating cavity is started for a heating reaction, and after the heating reaction is completed, the bypass gas circuit is started to blow the reacted crucible from the carrying assembly into the heating chamber for heating cleanin
