Damping device for flue gas electric heater

The invention belongs to the technical field of flue gas electric heaters, and particularly relates to a damping device for a flue gas electric heater, the damping device comprises a protective outer shell and a heating inner shell mounted in the protective outer shell, and the heating inner shell and the protective outer shell are supported and connected through a buffer mechanism; the buffering mechanism comprises a shock absorber, a buffering base installed at one end of the shock absorber and a buffering spring arranged on the outer side of the shock absorber in a sleeving mode, and a supporting base is arranged at one end of the shock absorber. The problem to be solved in the scheme is that heating elements such as an electric heating pipe in the heater are easy to damage due to long-term wind impact; according to the scheme, the protective outer shell and the heating inner shell are supported through the buffering mechanism, smoke enters the heating inner shell in the using process, wind power vibration
