Abstract
The liquid heater comprises an inner container, a coupler, a heating pipe and a PTC heater are arranged at the bottom of the inner container, an arc-shaped wall extending upwards is arranged at the bottom of the inner container, the heating pipe is arranged on the arc-shaped wall in a winding mode, the two ends of the heating pipe are arranged in an up-down staggered mode, and the coupler is located on the inner ring of the heating pipe. The heating pipe is provided with a first pipe section close to the coupler and a second pipe section away from the coupler, an installation avoiding area is formed between the coupler and the second pipe section, and the PTC heater is arranged in the installation avoiding area and is close to the staggered position of the two ends of the heating pipe. Due to the arrangement of the heating pipe, heat can be more evenly distributed on the inner container, a local high-temperature area caused by linear arrangement of a traditional C-shaped heating pipe is avoided, and the liquid heating uniformity is improved. The PTC heater is located in the installation avoiding area between the coupler and the heating pipe, so that more sufficient space is provided for installation and maintenance of the PTC heater, the installation difficulty is reduced, and the safety distance is easier to guarantee.
