An electric heater is a popular electric heating device in the world. The device is used for heating, preserving heat and heating flowing liquid and gaseous media. When a heating medium is heated by an electric heater under the action of pressure, the huge heat generated in the working process of an electric heating element is uniformly taken away by adopting the fluid thermodynamic principle, so that the temperature of the heated medium meets the process requirements of users, and in the utility model patent with the publication number of CN201363893Y, a high-pressure detachable electric heater assembly is disclosed, which comprises an electric heating pipe, an electric heating pipe fixing plate, an external thread sealing joint, a gland nut, a first sealing sleeve and a second sealing sleeve. Is characterized in that a sealing sleeve (I) and a sealing sleeve (II) with elasticity are arranged in the compression nut. When the compression nut is screwed, the sealing sleeve (I) and the sealing sleeve (II) are tightly clamped on the outer circular wall of the electric heating tube to generate a sealing effect, so that the interior of the electric heater barrel is kept in a high-pressure state.
