Abstract
The utility model relates to a constant temperature phase change heat storage bag for foot bath, which comprises a metal shell and a phase change material arranged in the metal shell; the metal shell is in an ellipsoid shape, a plurality of pairs of through holes are arranged on the metal shell, and a metal pipeline with two ends fixedly connected with the metal shell is arranged between each pair of through holes to form a closed cavity; the phase-change material is arranged in the closed cavity, adopts sodium acetate trihydrate, absorbs heat to melt when the phase-change temperature is higher than the phase-change temperature of the phase-change material, and releases heat to solidify when the phase-change temperature is lower than the phase-change temperature of the phase-change material. The utility model discloses need not the circular telegram during the use, simple structure, convenient and practical, low price. When the foot bath bucket is used, only the foot bath bucket needs to be placed into the bucket, hot water is poured into the bucket, the heat storage bag absorbs heat quickly and enables the water temperature to fall, then the phase change material begins to solidify and release heat after the water temperature falls to be lower than the phase change temperature, the heat storage bag enables the surrounding water temperature to be maintained at the temperature suitable for foot bath and continues for a period of time, and the requirement of constant-temperature foot bath is met.
Description
Technical Field
The utility model relates to an articles for daily use especially relates to a constant temperature phase transition heat accumulation package for lavipeditum.
Background
As the living standard is improved, the requirements of people on the quality of life are higher and higher, and the foot bath can promote blood flow, relax the channels and collaterals and relieve pressure after work or before sleep.
At present, the electric heating foot soaking basin on the market has greatly increased dangerousness due to the reason of electrification, is generally expensive, and can not be used in a student dormitory even as a high-power electric appliance. Some foot soaking basins also use phase-change materials, and Chinese patent documents (publication number: CN204654745U discloses a relatively constant temperature foot tub composed of phase change material. But the heat exchange area of the phase-change material and water is too small, so that the rapid heating through phase-change reaction is difficult in a short time, and meanwhile, the barrel is very heavy due to the fact that the phase-change material is filled in the barrel, the foot bottom is also easily scalded in a chronic manner due to the direct contact of the foot bottom and the heat conduction inner layer, and the defect is very obvious.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the defect that involves in the background art, provide a constant temperature phase transition heat retaining package for lavipeditum, simple structure, convenient to use, reasonable in design satisfies the demand of steeping foot in the dormitory.
The utility model discloses a solve above-mentioned technical problem and adopt following technical scheme:
a constant-temperature phase-change heat storage bag for foot bath comprises a metal shell and a phase-change material arranged in the metal shell;
the metal shell is in an ellipsoid shape, a plurality of pairs of through holes are arranged on the metal shell, and a metal pipeline with two ends fixedly connected with the metal shell is arranged between each pair of through holes to form a closed cavity;
the phase-change material is arranged in the closed cavity, adopts sodium acetate trihydrate, absorbs heat to melt when the phase-change temperature is higher than the phase-change temperature of the phase-change material, and releases heat to solidify when the phase-change temperature is lower than the phase-change temperature of the phase-change material.
The metal pipeline is used for increasing the heat transfer area of the phase change material and water.
As a further optimization scheme of the constant-temperature phase change heat storage pack for the foot bath, a rubber layer for heat insulation is arranged on the upper end face of the metal shell.
As a further optimization scheme of the constant-temperature phase-change heat storage bag for foot bath, a plurality of rubber balls for anti-skidding and massage are evenly arranged on the rubber layer.
As a further optimization scheme of the constant-temperature phase-change heat storage bag for the foot bath, the thickness of the metal shell and the metal pipeline is 1 mm.
The utility model adopts the above technical scheme to compare with prior art, have following technological effect:
the utility model discloses need not the circular telegram during the use, simple structure, convenient and practical, low price. When the foot bath bucket is used, only the foot bath bucket needs to be placed into the bucket, hot water is poured into the bucket, the heat storage bag absorbs heat quickly and enables the water temperature to fall, then the phase change material starts to solidify and release heat after the water temperature falls to be lower than the phase change temperature, the heat storage bag enables the surrounding water temperature to be maintained at the temperature suitable for foot bath and lasts for a period of time, and the requirement of constant-temperature foot bath is met.
