Description

Technical Field

[0001] The utility model relates to the technical field of electric heating tubes, in particular to a heater armored electric heating tube. Background Art

[0002] Armored heater is a common heating equipment. Its working principle is to use electrical energy to convert electrical energy into thermal energy, and transfer the thermal energy to the heated object by conduction, convection and radiation. The armored heater is mainly composed of a heating element, an insulating layer, a shell and a control system. The heating element of the armored heater is its core part. The heating element usually adopts alloy resistance wire or electric heating tube.

[0003] After the heater has been used for a period of time, scale will form inside the heater and on the surface of the electric heating tube. As the use time increases, the scale will become thicker and thicker, which will not only reduce the capacity of the heater, but also reduce the heating efficiency. The scale is also troublesome to clean. Therefore, the utility model provides a heater armored electric heating tube to solve the problems raised in the above background technology.

[0031] The supporting base 2 includes a No. 2 shell 202, a fixed block 210, a universal wheel 211 and a No. 3 shell 206. A gear 208 is rotatably arranged in the middle of the No. 2 shell 202, which is conducive to connecting the No. 1 rack 203 and the No. 2 rack 207. The No. 1 rack 203 and the No. 2 rack 207 are slidingly arranged on both sides of the interior of the No. 2 shell 202, which is conducive to installing the connecting plate 209 and the universal wheel 211. The No. 2 rack 207 and the No. 1 rack 203 are both meshed with the gear 208. A sliding cover 201 is slidingly arranged on the upper end of the interior of the No. 2 shell 202, which is conducive to limiting one of the No. 1 rack 203 and the No. 2 rack 207.

[0032] A water inlet 102 is provided between the first shell 101 and the partition 103, which is conducive to filling the water source. A motor 105 is fixedly provided at the upper end of the transmission shaft 106, which is conducive to driving the transmission shaft 106 to rotate. The motor 105 is fixedly provided at the upper end of the first shell 101. The upper and lower ends of the electric heating tube body 104 are fixedly provided with fixing frames 111, which is conducive to making the electric heating tube body 104 more stable.
