The invention relates to an improved electric heating water kettle, which comprises a kettle body, a kettle cover, a heating component and a temperature control component, wherein the kettle body comprises a kettle opening and a kettle nozzle, the kettle cover is detachably buckled and arranged on the kettle opening, a water outlet passage communicated with the inside of the kettle body and the kettle nozzle is arranged on the kettle cover, and in addition, an opening and closing mechanism used for opening and closing the water outlet passage is also arranged on the kettle cover. Because the water outlet passage and the opening and closing mechanism are arranged in the kettle cover in a centralized way, compared with the scattered arrangement mode of the opening and closing mechanism of the existing water kettle, the arrangement mode has the advantage that the structure is simpler. In addition, the water outlet passage and the opening and closing mechanism used for controlling the opening and the closing of the water outlet passage are both arranged on the kettle cover, and in addition, the kettle cover is a component detachably buckled and arranged on the kettle opening, so production personnel do not need to consider the strict correspondence of the kettle cover and the kettle body, and the production and the assembly are very simple and convenient.
