[0002] Electric heater is an internationally popular electric heating device. It is used to increase the temperature, keep warm and heat the flowing liquid and gaseous medium. When the heating medium passes through the heating chamber of the electric heater under pressure, the huge heat generated by the electric heating element is evenly taken away by the principle of fluid thermodynamics, so that the temperature of the heated medium meets the user's process requirements. With the increasing quality of life, in order to improve the indoor temperature, household electric heaters have also entered people's lives. Existing household heaters are generally heated by heating tubes, and then spread through the air to diffuse the heat to the outside world to achieve heating.

[0003] The existing household electric heaters are not convenient for adjusting the height when dispersing heat. At the same time, the heat diffusion angle is limited and not convenient for adjustment, thereby not being convenient for improving the heat diffusion effect. Therefore, an adjustable electric heater is proposed to address the above problems. Utility Model Content

After the height is adjusted, it can be locked by the locking mechanism 9, so as to facilitate the adjustment of the height of the electric heater. At the same time, the heat diffusion can be rotated to increase the diffusion range, thereby facilitating the improvement of the heat diffusion effect.

[0022] Furthermore, a telescopic hole 12 corresponding to the telescopic rod 4 is formed on the upper end surface of the support column 3 , and the telescopic rod 4 can be lifted, slidably inserted into the telescopic hole 12 .

[0023] During operation, the telescopic rod 4 can be installed on the support column 3 by the design of the telescopic hole 12.
