Description

Technical Field

[0001] The utility model relates to the technical field of electric heaters, in particular to an air electric heater. Background Art

[0002] A heater is a heating device that converts electrical energy into thermal energy. It is used to heat, insulate or heat flowing liquid or gaseous media. Among them, an air electric heater is a heating device that heats the dehumidified and filtered compressed air through an electric heating tube and then sends it out.

[0003] At present, the air electric heaters on the market use multiple bolts to seal the junction box and the electric heating tube to the heater shell through the connecting plate. When repairing and replacing parts, they need to be removed and installed one by one, which is time-consuming and labor-intensive. In addition, when the bolts are not tightened in place or fall off, the pressure inside the heater cannot be maintained, resulting in accidents. In the related technology, a baffle and an electric push rod are fixed by setting a limit device on both sides of the shell. The electric push rod pushes the fixed plate to compress the spring and then move it downward, thereby driving the hook to descend and fix the mounting plate. As the electric push rod contracts and the spring returns to its original position, the fixed plate is pulled to fasten the connecting plate and the mounting plate together. Although it is convenient for installation and disassembly, its structure is relatively complicated, and more structures are directly protected outside, which is easily damaged by external force collision, affecting the normal use of the air electric heater.
