Background

Containers filled with high-temperature liquid are frequently used in work and life, such as thermos bottles common in daily life, for hot water heat preservation, or soup bottles for heat transfer and heating. However, due to inevitable heat loss and limited capacity of the container, the temperature of the liquid in the container often cannot meet the use requirements with increasing standing time, especially for the container used for heat transfer such as soup and the like, through multiple heat conduction modes, wherein the limited amount of hot water stored therein drops very quickly, only short heating time can be provided, and the hot water needs to be replaced repeatedly for continuous use.

Accordingly, those skilled in the art have sought to develop a container with a pre-heat block to extend the time that the liquid in the container is maintained at a higher temperature.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, the technical problem to be solved by the present invention is the drawback that the high temperature cannot be maintained for a long time due to heat dissipation in the present container.

Further, the heat storage material comprises one or a combination of a heat conduction metal, a sensible heat storage material and a phase change heat storage material. The preheating block in the container body is in contact with liquid and has the constant temperature and heat preservation effect through continuous energy transfer.

The sensible heat storage material comprises sand, cobblestones, rocks, magnesium-iron heat storage bricks, magnesium-aluminum heat storage bricks and the like; the sensible heat storage material stores heat by utilizing the temperature change process of a substance, and the sensible heat storage material can adopt direct contact type heat exchange or is a heat storage medium, so the heat storage and release processes are relatively simple. The phase-change heat storage material is a substance for storing latent heat by utilizing heat absorbed or released by the substance in the phase-change process, and has the advantages of high heat storage density, stable performance, approximately constant temperature and easy control in the phase-change process and the like. Since some phase-change heat storage materials change according to solid-solid phase change, solid-liquid phase change and the like of the materials, a mode of wrapping the heat conducting metal layer outside the phase-change heat storage materials can be selected, for example, wrapping a layer of aluminum foil outside the phase-change heat storage materials.

Furthermore, a water injection pipe is arranged in the cavity, the top end of the water injection pipe is positioned at the cavity opening, small holes are formed in the water injection pipe at intervals, and buffer parts are arranged at two ends of the water injection pipe.

Further, the preheating block has a fin portion extending outward from the middle.

Furthermore, a through hole is communicated in the middle of the preheating block and is sleeved outside the water injection pipe, and a plurality of grooves are circumferentially arranged on the preheating block so as to facilitate water injection and water outlet more thoroughly.

In one embodiment of the invention, the container body is made of a thermally conductive material.

Preferably, the thermally conductive material comprises copper, iron, aluminum, and alloys of the foregoing.

The invention is carried out according to the following steps when in use:

1. the preheating block is heated by boiled water or other heating devices, so that the preheating block can absorb heat fully;

2. the container is filled with boiled water to make the preheating block contact with the boiled water, when the water temperature in the cavity is higher than that of the preheating block, the preheating block can continuously absorb heat until the temperature is balanced, and when the water temperature in the cavity is lower than that of the preheating block, the preheating block can continuously release heat to be balanced with the water, so that the heat preservation effect is achieved.

The invention realizes heat balance by continuously releasing heat from the preheating block to water in the container by arranging the preheating block in the container, is beneficial to heat preservation of water, and prolongs the heat preservation or heat supply time of the container.
