The invention relates to the technical field of electric heaters, in particular to a vibration-reduction anti-impact air flue type electric heater. The electric heater comprises an air flue box body,a vibration reduction bottom plate, electric heating pipes, a junction box and a hollow supporting pipe, wherein a through port is formed in the upper part of the air flue box body, and a bearing plate is arranged in the through port; the electric heating pipes are vertically arranged on the bearing plate, and the upper end parts of the electric heating pipes penetrate through the hollow supporting pipe and are arranged in the junction box; and a sealing elastic connecting part is arranged between the bearing plate and the side wall of the through port, the bearing plate is connected with thevibration reduction bottom plate through a supporting frame. According to the air flue type electric heater, the problems that an electric heating element in an existing air flue type electric heateris generally directly welded to an air flue outer shell, the vibration of a fan can easily cause damages on the electric heating element, the production cost is increased, the service life of the electric heater is reduced, and the production efficiency is influenced are solved; and in addition, the electric heater is simple in structure, implement and operation are easy, and the electric heater is capable of being widely popularized and used.
