Description
Technical Field
The utility model relates to a thermos cup technical field especially relates to a novel phase change material heat-retaining thermos cup.
Background
The vacuum cup is taken as a necessity of daily life of people, most of the existing vacuum cups are water containers made of ceramic or stainless steel and vacuum layers, the heat dissipation rate is high, the heat preservation time is too short, and the performance of the vacuum cup can be deteriorated along with time. In order to solve the problems, the vacuum cup is improved on the basis of the traditional vacuum cup, the heat preservation layer of the vacuum cup is filled with paraffin and a composite phase-change material thereof, on one hand, the heat of boiled water in the vacuum cup can be stored by the phase-change material, the temperature of the boiled water is reduced to a temperature suitable for drinking, on the other hand, the heat stored by the phase-change material can prolong the heat preservation time of the vacuum cup, and the temperature of the vacuum cup is controlled to be between 40 ℃ and 60 ℃. In addition, as the phase-change material can slowly release a large amount of latent heat in the phase-change process, the use occasions are greatly increased, and the phase-change material not only can be used for heat preservation, but also can be used for heating. For example, the heat-insulation bag can be used for heat insulation of liquid such as milk and the like which cannot resist high temperature, or hot water needs to be drunk in outdoor activities, cold water can be poured into the bag to be heated, food with low temperature can be heated, and the use in the outdoor or non-heating occasions is effectively expanded.
SUMMERY OF THE UTILITY MODEL
The basic working principle of the utility model is that when the phase-change material vacuum cup is internally electrically heated, the phase-change material in the vacuum cup absorbs heat, the temperature rises, when the temperature reaches the phase-change temperature, the phase-change material starts to melt and becomes liquid from solid, the temperature is basically kept unchanged at the moment, the heating is continued, the liquid temperature starts to rise again, and when the temperature is heated to a set temperature, the heating is stopped; when the heat-preserving cup is used, the phase-change material in the heat-stored heat-preserving cup begins to release heat, and the temperature change of the phase-change material is just opposite to the temperature change during heating until the heat release is finished.
Furthermore, phase-change materials are filled in the gaps of the resistance wires to form a heat storage layer.
Furthermore, the resistance wire is connected with the temperature control induction switch by a lead.
Furthermore, the transformer and the resistance wire form a circuit loop.
Furthermore, the heating device is composed of high-temperature resistance wires.
Further, the liquid storage cavity is a cylindrical inner cavity made of stainless steel.
Further, the outer hard shell is made of stainless steel material.
Furthermore, the heat insulation layer is a cavity formed by sealing an outer hard shell and the inner wall of the stainless steel, and the cavity is vacuumized.
Compared with the prior art, the utility model discloses a phase change material, heat release time obviously will be longer than ordinary thermos cup, and it can keep comparatively stable heat release rate in the phase transition temperature range, and the control of stock solution intracavity temperature is also more even, and the phase transition of paraffin is exothermic more completely. The novel phase-change vacuum cup is filled with the phase-change material, latent heat is utilized, sensible heat is utilized, stored heat is large, heat release is uniform, and heat release time is long. The temperature of the liquid is controlled within the acceptable range of people, and the selected phase-change material is non-toxic and tasteless, so that the safety of the human body is protected. The safety is improved, and the number of applicable occasions and crowds is increased.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Examples are given. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses a novel heat-retaining thermos cup, include the novel heat-retaining thermos cup that fills for compound phase change material with paraffin/expanded graphite, including cup and bowl cover 5, the cup is equipped with stock solution chamber 4 according to the order, heat storage layer 3, insulating layer 2, outside crust 1, packs phase change material in the heat storage layer 3, is equipped with the resistance wire in the heat storage layer 3, connects resistance wire and temperature control inductive switch 6's one end with wire 61, and the heating device resistance wire is spiral and arranges, and temperature control inductive switch 6's the other end is connected with transformer 7's low-voltage end, and transformer 7's high-voltage end is connected with external power supply, can heat phase change material after the circular telegram and carry out the heat-retaining, and bowl cover 5 is a rotatable formula bowl cover, insulating layer 2 is the cavity that is formed by outside crust 1 and the sealing-in of stainless steel inner wall, evacuation in the cavity. The switching of the vacuum cup, the transformer 7 and the temperature controlled inductive switch 6 during the engagement of the threads 8 is prior art and will not be described further herein.
Preferably, after being connected transformer 7 with external power supply, transformer 7 provides the electric quantity for the resistance wire, heat phase change material continuously, phase change material can release latent heat through the phase transition, can heat the heat preservation to the liquid in the stock solution intracavity made by the stainless steel, the melting is liquid phase change material behind the solid phase change material heating, the back is poured into to the boiling water, hot water temperature is higher, heat release rate is greater than phase change material to its rate of heating, consequently, hot water temperature drops to human best drinking water temperature 36 ~ 38 ℃ when, phase change material is almost equal rather than heat release rate to its rate of heating, keep warm lastingly with the water this moment, the water that lets the people drink always is not cold not scalding.
