Solid-liquid compound-phase variable-speed cooling constant-temperature cup and microwave heating constant-temperature cup

Abstract

The invention relates to a daily used vacuum cup, in particular to a compound-phase variable-speed cooling constant-temperature cup. The solid-liquid compound-phase variable-speed cooling constant-temperature cup comprises a cup lid and a cup body, wherein the cup lid is in sealed connection with the cup body, the cup body comprises an inner cup wall, a middle cup wall and an outer cup wall, the internal cavity of the inner cup wall forms a beverage containing cavity, the airtight cavity between the inner cup wall and the middle cup wall is filled with inorganic hydrous salt compound phase change liquid, the airtight cavity between the bottom of the inner cup wall and the bottom of the middle cup wall is designed into a phase change alloy rapid-cooling interlayer, and the phase change alloy rapid-cooling interlayer is provided with built-in low-melting-point phase change alloy. In a solid-liquid compound-phase variable-speed cooling microwave heating constant-temperature cup, the airtight cavity between the inner cup wall and the middle cup wall is filled with inorganic hydrous salt compound phase change liquid to form a phase change liquid heating cavity, one or more distributed rod-like microwave antennae are arranged in the phase change liquid heating cavity, and a solid-state microwave power source, a power supply part and a control system are arranged in a cup base.

Description

technical field [0001] The invention relates to a thermos cup for daily use, in particular to a composite phase-changing speed-cooling constant temperature cup. Background technique [0002] The thermos cup is generally a water container made of ceramic or stainless steel plus a vacuum insulation layer, usually consisting of a cup body and a cup cover. For the convenience of carrying, the cup lid and the cup lid adopt special structure and seals to seal tightly. Through reflection and vacuum insulation, the vacuum insulation layer can delay the heat dissipation of liquids such as water and beverages installed inside, so as to achieve the purpose of heat preservation for a long time. However, there is a problem with all kinds of thermos cups on the market: if the temperature of the initially loaded beverage is relatively high, such as putting boiling water into the thermos cup to keep it warm, it will still be too hot for the first 1-3 hours to drink directly; Warm water at...

Problems solved by technology

However, there is a problem with all kinds of thermos cups on the market: if the temperature of the initially loaded beverage is relatively high, such as putting boiling water into the thermos cup to keep it warm, it will still be too hot for the first 1-3 hours to drink directly; Warm water at -50°C, although it can be drunk directly at the beginning, the temperature will drop to an uncomfortable temperature after 2-3 hours

However, paraffin wax has low thermal conductivity and slow heat transfer when used for phase change heat preservation, so it is also difficult to quickly reduce hot drinks to the drinking temperature

[0004] Neither the vacuum insulation method nor the phase change latent heat insulation method can solve the problem of long-term insulation

More can't solve the purpose of determining the heat preservation temperature by the user

Although there are car heating water cups and USB interface heating water cups and other types of products on the market, they all use the heat generated by the "Joule effect" of current flowing through the conductor for heating, which is very inefficient, and requires an external power supply to work, and cannot be used in a portable way. automatic heating under
