Description

Liquid heater

Technical Field

The embodiment of the invention relates to small household electrical appliances, in particular to a liquid heater.

Background

The electric kettles, health preserving kettles and other products which are connected by the coupler in the market have more functions, for example, the electric kettle has the functions of heating water and preserving heat; the health preserving pot has the functions of boiling water, preserving heat, flower and fruit tea, nourishing soup and the like. When the function of the existing product is selected, the function selecting key is arranged on the power supply base, and the function is selected by operating the key.

If functional parameters, such as the temperature keeping temperature and the time for boiling the flower and fruit tea, need to be adjusted, the existing products are also adjusted by users through operating keys or knobs.

When the user operates the device, the user needs to move the arm for multiple times of moving operation, and the action is complex. Meanwhile, function selection and function parameter setting are realized by arranging keys on a UI operation interface, so that the cost is high and the requirement on structural space is high.

In order to solve the above problem, in patent CN 201720870095.1, a solution is proposed, in which when the kettle body is at a certain position, the sensor outputs a signal to control the working state of the system; further, different positions are set, and different functions are selected according to different positions. The kettle body and the base are required to be accurately aligned, the realization scheme is realized by a concave-convex shape between the kettle body and the base, and due to the concave-convex structure, when the kettle body rotates, if the size is not designed well, the resistance is larger, and the kettle is not beneficial to use; meanwhile, due to the limitation, when a user places the kettle body, the user needs to carry out alignment operation, and the kettle is not beneficial to the use of the user.

In addition, in patent CN201420366774.1, a solution is proposed, which is implemented by a kettle body and a base, and adopts a gear structure for transmission, and a gear on a power base is coupled with a gear at the bottom of the kettle body through a slot, and temperature adjustment is implemented by rotating the kettle body. According to the solution, because the base is grooved, waterproof treatment is required, and when the base is used for a long time, oil stains and dust are accumulated in the groove, so that the rotating timeliness is high, and the reliability is low; due to the plastic size, the gears may wear out after long-term use, resulting in unreliable transmission.

Generally, the technical scheme has high use requirement or production requirement.
