Phase change latent heat intermittent burning handwarmer

Abstract

The invention provides a phase change latent heat intermittent burning handwarmer. The phase change latent heat intermittent burning handwarmer comprises a warmer body and a warmer cover; a first heatstorage container is arranged in the warmer body, and is filled with a phase change heat storage medium; a first container cover is arranged at the top of the first heat storage container, and is provided with an exhaust hole; charcoals are placed above the first heat storage container; and ventilation holes for providing oxygen for combustion of the charcoals are arranged on the side wall of thewarmer body. The handwarmer is simple in structure, adopts phase change heat storage materials for heat storage, and can guarantee full combustion of the charcoals and long-time continuous warming.

Description

technical field [0001] The invention mainly relates to the technical field of portable heating tools, in particular to a phase change latent heat intermittent combustion hand stove. Background technique [0002] When doing field work in cold places, sometimes it is extremely inconvenient to wear gloves, such as vehicle emergency repair, field construction, fishing and cleaning aquatic products, etc. At this time, a hand warming tool is definitely needed. On duty in a sentry box with a small space, or in a tent sleeping in a cold environment, a heat source with low power but long-term continuous and stable work is also required. [0003] The portable electronic heating tool powered by a mobile power supply has the disadvantages of heavy battery weight, short continuous heating time, and long charging time. Living in areas without electricity for a long time, such as forest management, geological exploration, field exploration, etc., if there is no mobile power generation equ...

Problems solved by technology

Smoldering is the most commonly used combustion method, but it is prone to carbon monoxide poisoning. The indoor ventilation must be maintained throughout the process, but this is contrary to the original intention of pursuing heating

Second, the temperature is uncontrollable, high and low

When smoldering, the hand stove must be covered with insulation materials to ensure that the heat generated is sufficient to support the ignition of the charcoal, otherwise it is easy to turn off the fire, and empty burning will often cause the temperature of the hand stove to be too high, which will cause excessive heating to the outside and cause waste of charcoal

The third is that if only empty burning is used, on the one hand, charcoal needs to be added frequently, and on the other hand, the fire will be turned off if you are not careful.

However, the traditional hand stove cools down quickly, and a combustion aid is needed to re-ignite the charcoal, causing air pollution such as smog

At present, there is a hand stove that uses water as a heat storage material, but water can only be in a form of liquid (the temperature of the solid state is too low, and the volume of the gaseous state is too large), and the heat storage performance is limited, so it is not suitable for use on the hand stove with a small volume itself.
