Abstract
The utility model relates to a novel electric thermal bag. The novel electric thermal bag comprises a sealed shell and is characterized in that an inner material is arranged in the sealed shell, and an insulating sleeve is sleeved outside the sealed shell. The novel electric thermal bag has the advantages that 1, the insulating temperature is moderate (52-55 DEG C); 2, the insulating time is long (the 1000g electric thermal bag can be insulated for more than 8 hours); and 3, the heating way is convenient and rapid, and only 5-8 minutes are cost for heating by a microwave oven.
Description
Technical field
This utility model relates to warming article, and is particularly a kind of by microwave heating, has the not plug-in Novel hot treasured of overlength temperature retention time.
Background technology
Hot treasured is a kind of trade name, major function is to use for the heating of a health part, be named as the titles such as warm hand bag on the market more, mostly be greatly charge type, diameter 20cm, interior material are generally water or inserts (electric hot-water bag), and also having a kind of is hard electrical heating heat accumulation warm hand bag, two kinds of products all need electrical heating, warming limited time when using.But it is higher that this hot treasured has just charged electro-temperature, and hard electrical heating heat accumulation warm hand bag initial temperature even reach 130 ℃ is easy to occur the security incidents such as scald, fire.
Also have a kind of heat treasured not charge, Rebaodai the inside is a kind of sodium acetate supersaturated solution and sheet metal, when pulling sheet metal, solution forms small nucleus and ramp on the sheet metal surface, sodium acetate crystallizes into rapidly solid, this process is to want heat release, and temperature can reach about 50 ℃.The sodium acetate that needs when using for the second time should the heat treasured will form crystal by the mode of boiling water boiling reheats the saturated liquid state of being.This heat is precious easy to carry, can start heating service whenever and wherever possible, but warming limited time, general lasting 1 hour, and reuse more loaded down with trivial details, need to wrap in product outside towel heating about 10 minutes in the hot water of boiling, and exist because heat time heating time not or heat the inhomogeneous product that makes and can't use the drawback that causes product breakage with superheated.
Summary of the invention
The purpose of this utility model is to solve short, use inconvenience of warming time of the prior art, and accident-prone problem provides a kind of by the microwave oven Fast Heating, and the Novel hot with the relatively constant temperature retention time overlength of temperature is precious.
This utility model is achieved in that a kind of Novel hot is precious, and comprising: seal casinghousing is characterized in that: described seal casinghousing inside is equiped with interior material, is arranged with a muff outside seal casinghousing.
Preferably, described seal casinghousing includes but not limited to disc, square.
Preferably, the material of described seal casinghousing adopts polypropylene plastics.
Preferably, the material of described muff include but not limited to cotton, towelling, grab flannelette, Flocked fabric, velvet.
Preferably, described interior material is phase-change material.
Preferably, the transformation temperature of described phase-change material is 52-55 ℃.
Preferably, described phase-change material is sodium acetate.
Preferably, described muff is provided with the opening of packing into or taking out for seal casinghousing, and this opening pastes sealing by the burr that is arranged on the opening inside edge.
The utility model has the advantages that: 1, holding temperature moderate (52 ~ 55 ℃); 2, temperature retention time long (the hot treasured of 1000 grams can be incubated more than 8 hours); 3, mode of heating is convenient and swift, and microwave-oven-heating only needs 5 ~ 8 minutes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structural representation of muff in this utility model.
Below in conjunction with drawings and Examples this utility model is elaborated.
The specific embodiment
See also Fig. 1 and 2, shown in the figure a kind of Novel hot precious, its structure comprises: discoidal seal casinghousing 1, be equiped with phase-change material 2 in the sealing enclosure interior, phase-change material be sodium acetate, its transformation temperature is 52 ~ 55 ℃, this temperature is fit to the body heating and uses very much.Sodium acetate has quite high latent heat of phase change (greater than 220kJ/kg), can be good at storing and releasing energy.When the temperature of sodium acetate is higher than transformation temperature, beginning melting heat absorption, heat energy storage; When sodium acetate is lower than phase point temperature, begin to solidify heat release, discharge heat energy.And prevent the surfusion of sodium acetate by adding suitable nucleator, add thickening agent and prevent from repeatedly heating the phase lamination that causes.
Because when solid-state and liquid phase transformation occured phase-change material, variation by a small margin occured in volume, so the volume of housing is along with the pressure of phase-change material changes, adopt discoidal design can guarantee that the interior material of hot treasured is close to shell, be beneficial to heat transfer.The sealing 21 of seal casinghousing is the High-frequency machine heat-sealing, prevents the phase-change material outflow, improves the precious reliability of using of heat, thoroughly avoids the generation of security incident.
The material of described seal casinghousing adopts polypropylene plastics, this kind plastics can bear-20 ℃-120 ℃ variations in temperature, and it has lower thermal conductivity and higher heat distortion temperature, can delay the heat transmission, prolong temperature retention time, avoid simultaneously repeatedly heating the distortion that causes housing.Higher resistance to elevated temperatures can be avoided repeatedly heating and cause casing deformation simultaneously, and the plastic product of made is considered to unique and can at the plastic containers of microwave-oven-heating, be widely used in the production of various plastic food containers.
Simultaneously, reduce heat release rate for heat is precious, prolong temperature retention time and avoid simultaneously the human body of burning, can be furnished with a napped cotton fabric cover in the seal casinghousing outside, this cloth cover is consistent with the shape of seal casinghousing.As shown in Figure 3, the cloth cover is circular configuration also, and two openable covering of the fan openings 31 about the back side has are opened the covering of the fan opening and hot treasured can be packed into smoothly or take out.The burr that posts in the opening part correspondence of covering of the fan opening pastes 32, conveniently opens or closes.Like this, can improve the heating comfort level, avoid simultaneously causing low temperature to scald to the temperature-insensitive crowd.
Hot precious design parameter in the present embodiment is as follows: 20 centimetres of the diameters of seal casinghousing, 0.15 centimetre of thickness, shell weigh 120 grams.Interior material consists of sodium acetate 776, nucleator 8 grams, thickening agent 16 grams.During use, should be placed in the microwave oven by the heat treasured, heating is 6 minutes under 900 watts power, and hot precious surface temperature can reach 65 degree, and equilibrium temperature 55 is spent about 6 hours of persistent period, about 8 hours of the above temperature retention time of 40 degree, good warmth retention effect.
This utility model product can be used as daily heating usefulness in winter, also can be used as hot packing and uses, and can also use as the house pet heating pad simultaneously, needing also to can be used for to be incubated thermal protection in the thermal protection goods transportation way and uses.
Below only expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
