Title:
MULTIFUNCTIONAL HEATING AND HEAT PRESERVATION CONTAINER, CHARGING BASE AND COMBINATION
Document Type and Number:
WIPO Patent Application WO/2021/189371
Kind Code:
A1
Abstract:
Disclosed are a multifunctional heating and heat preservation container and a charging base thereof. The multifunctional heating and heat preservation container comprises a container main body (30), with the container main body (30) comprising a container inner lining (8), and a container housing (10), which forms a vacuum cavity (9) with the container inner lining (8) and enables the bottom of the container inner lining (8) to be exposed, is arranged on the peripheral side of the container inner lining (8). The charging base comprises a base housing (1), an ejector pin (2), which is in contact with a charging ring (214), is arranged in the base housing (1), an insulating layer (3) is sleeved on the ejector pin (2), an elastic member (4) which elastically ejects the ejector pin (2) towards the outside of the base housing (1) to enable the ejector pin (2) to move out of or retract into the base housing (1) is sleeved on the insulating layer (3), and a conductive terminal (5) is connected to the ejector pin (2). The problems whereby a cup body of an existing temperature control cup uses a single-layer steel plate structure, the cup body dissipates heat quickly, and heat preservation completely depends on electric energy heating, such that a battery which is in the temperature control bottom of the container and is used for power supply consumes electricity quickly, are solved; and the problems whereby a spring in an existing charging base is arranged in an ejector pin, and the spring is prone to failure due to an overlarge current in the power-on process of the charging base with the outside, such that the ejector pin cannot rebound and reset, are solved.
