Description

Soft electric warming bag

Technical field

The utility model relates to a kind of electrical heating hot-water bottle, especially a kind of soft electric warming bag with the low-temperature heat of insulated electro hot line, and it mainly is applicable to body heating and other warming purposes.

Background technology

In the prior art, the electric warming bag publication of very many employing heating heating is arranged.As Chinese patent ZL96241773.4, adorn common resistance (heat) silk in it, so its appearance bag must be resistant to elevated temperatures insulation crust, selecting for use of material has been subjected to very big restriction: can not overlap between the heating wire, must become certain spacing to arrange, otherwise the meeting short circuit implements comparatively difficulty.For another example, Chinese patent ZL02294811.2---have the electric warming bag of low-temperature heat head, though do not need resistant to elevated temperatures bag body, but the heating head temperature reduces when heating in order to make, and must increase the surface area of heating head, and this makes that the heating head volume is bigger, and in use, because bag body softness, hand can touch the heating head in bag body, and comfort is relatively poor.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of more practical comfortable soft electric warming bag, and it does not have hard heating head, double insulation, and the operating temperature of its thread insulated electro hot line is below the temperature that bag stature material commonly used and insulating materials are allowed.

The technical scheme in the invention for solving the above technical problem is: this soft electric heating bag comprises flexible pouch body, socket cover, seal receptacle, heating wire and liquid injection hole, its design feature is: described heating wire is that power density is not more than 50 watts/meter low temperature rheostan, and this heating wire can be agglomerating or be overlapped agglomerating.

The utility model also can be provided with the heating wire casting die, and this heating wire casting die links to each other with the flexible pouch body.

Heating wire casting die described in the utility model can be a mesh film shape.

Heating wire described in the utility model is made up of outsourcing insulation and thermo electric material silk, and its profile is elongated thread.

Heating wire described in the utility model can be agglomerating or be overlapped and agglomeratingly be meant that it can roll into a ball the 3D shape that can be contained in the flexible pouch body.

Heating wire described in the utility model can link to each other with seal receptacle by lead, also can directly link to each other with seal receptacle.

Heating wire described in the utility model can be single, also can be several parallel connections.

The utility model compared with prior art has the following advantages and effect: 1, reasonable in design, novelty, and thermo electric material silk surface is wrapped with outsourcing insulation, thermo electric material silk operating temperature is low, can not burn outsourcing insulation, can overlap between the heating wire, electric warming bag electrical strength height; 2, the inner no hard thing of electric warming bag, the soft no bone of entire body, good hand touch; 3, but water filling in the electric warming bag, oil or other phase change material heat more even as heat-storage medium.

The specific embodiment

Embodiment 1:

Referring to Fig. 1, Fig. 2, the utility model mainly is made up of socket cover 1, seal receptacle 2, heating wire 5, flexible pouch body 7.Wherein heating wire 5 is made up of outsourcing insulation 8 and thermo electric material silk 9, socket cover 1 combines with seal receptacle 2, seal receptacle 2 sealed junctions are combined on the flexible pouch body 7, the material of flexible pouch body 7 usefulness compactness softnesses is made, as rubber, PVC leather etc., inject heat storage medium 6 by the liquid injection hole on it 12, as water, wet goods.

In the present embodiment, adopt soft lead 3 to link to each other between heating wire 5 and the seal receptacle 2, seal with seal head 10 junction.Heating wire 5 is that security reliability height, technology are convenient with the advantage that seal receptacle 2 is connected by lead 3.

Dry combustion method also can be provided with heating wire casting die 11 in order to prevent heating wire 5 perks to break away from liquid level, and heating wire 5 is in bag below the interior liquid level all the time.Heating wire casting die 11 can be a pressure zone, is connected the inside of flexible pouch body 7, is used for fixing high resistance heating wire 5, can be single or several; Heating wire casting die 11 also can be the mesh film, its optimum shape is a mesh, mesh can be circular (referring to Fig. 7), also square (referring to Fig. 8), or other geometry, its edge shape can be hexagon, circle, square or other geometry, the mesh film can be with the film shaping (see figure 7) of punching, and also fishing net shape structure (see figure 8) can certainly be other structure, as long as can play the casting die effect, its edge is connected the inside of flexible pouch body 7.

Referring to Fig. 6, heating wire 5 of the present utility model is different from heating of the prior art, as heating wire, but a kind of low temperature rheostan, length is more than ten meter or tens of rice; Its power density generally is lower than 50 watts/meter, and as the electric warming bag of 500W heating power, its heating wire is designed to about 25 meters long; Its operating temperature generally is lower than 150 ℃, make the heating wire 5 can be as common insulated conductor, be made up of outsourcing insulation 8 and thermo electric material silk 9, outsourcing insulation 8 can be PVC, rubber etc., and thermo electric material silk 9 can be metal electric heating silk or other thermo electric material silk.Therefore heating wire 5 can be rolled into a ball 3D shapes such as balling-up or ring, is placed in easily in the flexible pouch body 7, and can cause short circuit because of the heating wire overlap joint.

In order to control the temperature of electric warming bag easily, also can be provided with temperature controller 4 in the seal receptacle 2 of the present utility model.

During use, inject heat storage medium 6 by liquid injection hole 12 earlier, connect power supply again, electric warming bag begins heating, and when being heated to design temperature, outage can be warmed oneself, and when the electric warming bag temperature reduced, heating was again used so repeatedly.When not using for a long time, can be by liquid injection hole 12 to pouring out heat storage medium 6, convenient collection.

Embodiment 2:

Referring to Fig. 3, the primary structure of present embodiment is identical with embodiment 1, but its heating wire 5 directly links to each other with seal receptacle 2.

Embodiment 3:

Referring to Fig. 4, the primary structure of present embodiment is identical with embodiment 1, but heating wire 5 is divided into several bursts of parallel connections.The advantage of 5 several bursts of parallel connections of heating wire is to improve electric warming bag power, and implements easily on technology.

Embodiment 4:

Referring to Fig. 5, the primary structure of present embodiment is identical with embodiment 1, but its heating wire 5 directly links to each other with seal receptacle 2, and is divided into several bursts of parallel connections.
