Abstract
Description
Technical Field
[0001] This utility model relates to the field of home appliance technology, and in particular to a power base and a liquid heating container. Background Technology
[0002] An existing liquid heating container includes a kettle body assembly and a power base. The power base includes a base and a support cover. The base has a mounting cavity with an upper port. The support cover is positioned downwards within the mounting cavity. A first electrical connector is located within the mounting cavity. The connecting portion of the first electrical connector protrudes upwards through the support cover. A second electrical connector is located at the bottom of the kettle body assembly. When using the liquid heating container, the user places the kettle body assembly on the power base, with the top surface of the support cover supporting the bottom surface of the kettle body assembly. The first and second electrical connectors are electrically connected, thereby achieving electrical communication between the power base and the kettle body assembly. However… Because the base is made of plastic and injection molded, it gives the impression of a low-end product with poor aesthetics, reducing users' desire to buy. To improve the aesthetics of the liquid heating container, one existing method is to inlay a metal ring on the outside of the base. The current process for this type of power base requires first molding the base and support cover, then fitting the metal ring onto the outer wall of the base, and using a mold to fold the upper part of the metal ring inward and downward until the upper side of the metal ring abuts against the top surface of the outer wall of the base. Finally, the support cover is placed on the mounting cavity, with the side wall of the support cover abutting against the inwardly folded part of the metal ring.
[0003] However, this process has two drawbacks: First, the metal ring is first fitted onto the outer wall of the base and then the upper part of the metal ring is folded inward to form the shape using a mold, which can easily damage the base and also carries the risk of damaging the metal ring; Second, the assembly process of the metal ring and the base is complex. Utility Model Content
[0004] To address the aforementioned problems in the prior art, this utility model provides a power base, including a support assembly.

The groove surrounds the installation hole, and the installation hole allows the connection part of the first electrical connector to pass through.
[0013] To address the aforementioned problems in the prior art, this utility model provides a liquid heating container, including a kettle body assembly and a power base. The bottom of the kettle body assembly is provided with a second electrical connector. The kettle body assembly is placed on a first support portion, and the support portion supports the kettle body assembly upwards. The connection portion of the first electrical connector is electrically connected to the connection portion of the second electrical connector.
