Description

Stored-heat warm bag

This utility model relates to a kind of daily living article, particularly a kind ofly is used to warm oneself and the warm bag of the heat-storage used of thermotherapy.

Disclosed heat-storage heating installation in Japanese kokai publication sho 62-38155 and the CN87212230U patent, its heater is two mutual independent sectors with storage thermal capacitance device, referring to Fig. 1, its electric heater 1 is to be placed between storage thermal capacitance device 3 outsides or 3 liang of interlayers of container, therefore heater 1 and 3 thermal of container are loose, heat-conducting effect is poor, and heat conduction is inhomogeneous, for addressing this problem, generally between heater 1 and storage thermal capacitance device 3, add soaking plate 2, to solve the inhomogeneous and heater problem that storage thermal capacitance device that bring scorches easily to storage thermal capacitance general ability portion is overheated of heating.

In addition, the temperature control of heater at present adopts bimetallic thermostat or PTC heater element to heat mostly, though bimetallic thermostat cost is low, but adjust time-consuming in the use, and not really stable, though the heating of the solid PTC element of employing is concentrated, exist long shortcoming heat time heating time, software PTC is also because of the cost height, complex structure and fail to promote the use of.

Generally there is heat-insulation layer present this device outside and does not add two big classes of heat-insulation layer, though the former is long the heat release time, surperficial heating temperature is low, does not reach the preferable effect of thermotherapy or heating, and the latter shortens the serious heat release time of heat leakage because of there being heat-insulation layer.

The purpose of this utility model is just in overcoming the above-mentioned shortcoming and defect of existing in prior technology, and provide a kind of heating wire and heat-storing material to mould to be solidified as a whole, have heat-insulation layer and local heating face, constitute the warm bag of heat-storage of temperature controller by bidirectional triode thyristor and electronic ceramics temperature-sensitive element.

Basic structure of the present utility model is seen Fig. 2.Its feature is: utilize foam plastics that heating wire is moulded solid portion within it, then in foam plastics in the dipping fill heat-storing material to form the monoblock type storage body, in the outside pressing of storage body one rubber or plastic sheath are arranged then, at rubber or plastic sheath outside one heat-insulation layer and overcoat are arranged, when the attaching plug on the handle is inserted power supply, electric current by being installed in handle inside bidirectional triode thyristor and the control circuit of formation such as ceramic temperature-sensitive element make the heating wire heating, and store heat by heat-storing material, after reaching uniform temperature, controllable silicon disconnects, storage accumulation of heat bundle can be with use.

Fig. 1 is the warm bag of an existing separate type storage heat principle schematic.

Fig. 2 is this utility model structure principle chart.

Fig. 3 is that the A of Fig. 2 is to view.

Fig. 4 is circuit theory diagrams of the present utility model.

Below in conjunction with embodiment and accompanying drawing thereof this utility model is described.

Architectural feature of the present utility model is:

A: the foam plastics 5 that dipping is adsorbed with heat-storing material 19 will uniform heating wire 4 be moulded and is consolidated within it that portion forms a monoblock type storage body 20, be enclosed with closed rubber or a plastic sheath 6 identical at storage body 20 outer surfaces with its shape, at closed rubber or plastic sheath 6 outsides one heat-insulation layer 7 is arranged, heating face 15 positions do not have heat-insulation layer 7, there is the overcoat 8 of a sealing heat-insulation layer outside, have at the rubber of storage body 20 1 sides or plastic sheath mouth 13 place's clampings and control circuit and plug 16 to be housed, the insulation handle 11 of socket 18 in one;

B: the heating wire 4 in the storage formula body 20 is in series with dropping resistor R1 by going between after 22, its two ends are parallel with current-limiting resistance R2 and light emitting diode D, dropping resistor R1 one end is connected with bidirectional triode thyristor 21, on lead-in wire 22, be parallel with electronic ceramics temperature-sensitive element 10, electronic ceramics temperature-sensitive element 10 is housed in the insulation sleeve 9, insulation sleeve 9 passes the 13 back spies of cover mouth and is placed in the storage formula body 20, sees Fig. 2 and Fig. 4.

Architectural feature of the present utility model also is:

A: two semi-insulating handles 11 of flat duckbill are being overlapped mouth 13 both sides by screw 12 by clamping, on the insulation handle 11 luminous 2 utmost point pipe D that communicate with circuit are installed, plug 16 and socket 18 activity insertings on the insulation handle 11 are connected with lead 17 and plug 23 on the plug 16; See Fig. 2 and Fig. 3,

B: be equipped with in the outside of the rubber of flat-shaped oval storage body 20 or plastic sheath 6 one with the safety switch 14 of circuit communication; See Fig. 2 and Fig. 4,

C: a side of flat-shaped oval storage body 20 has an oval heating face 15, directly contact between the overcoat 8 at heating face 15 positions and rubber or the plastic sheath 6, and with other position of this face etc. flat or projection slightly.

Use principle of the present utility model is:

When needs thermotherapy or heating, can insert supply socket to plug 23 makes circuit connect alternating current, electronic ceramics temperature-sensitive element 10 is low resistive state at this moment, therefore the trigger current that flows through it is big, bidirectional triode thyristor 21 is triggered lead energy, makes heating wire 4 heatings, and heat is led storage give the storage body 20 that is impregnated with heat-storing material 19, can deliquescing gradually after the storage body heat absorption, store when hot, the light emitting diode D on the handle 11 is luminous.When storage body 20 temperature rise gradually, its temperature is conducted the temperature-sensitive element of giving in it 10 by the insulation sleeve 9 that is housed in the storage body 20, when temperature-sensitive element 10 temperature reach 80 ℃, the resistance of temperature-sensitive element increases to its electric current of flowing through and is reduced to the degree that can not trigger bidirectional triode thyristor 21, controllable silicon 21 shutoffs this moment, light emitting diode D extinguishes, and indication storage heat finishes.Can pull up plug 23 this moment, and will warm up bag and have the one side of heating face 15 to be placed on to need thermotherapy or heating to get final product with the position.

Plug 23 can not pulled up yet during use, and promptly the use of hot limit is store on the limit.Storage body 20 is along with the prolongation of service time, and its temperature constantly descends and crystal hardened gradually.

Being perfectly safe in order to guarantee to use put safety switch 14 in rubber sleeve 6 outsides, and its effect is rubber sleeve 6 outwards to be expanded and then compression makes switch 14 short circuits, reaches the effect of safe handling.

Therefore advantage of the present utility model is:

Because heating wire 4 adopted the high-temperature insulation heating wire, and is distributed on storage body 20 inside, so heating wire and storage body thermal contact conductance area are big, and thermal is tight, so the preheating speed is fast, and thermal efficiency height, thermal losses is little.

In addition, owing to circuit mainly is made of electronic ceramics temperature-

sensitive element

10 and 21 two main components and parts of bidirectional triode thyristor, so circuit is simple, and reliable, cost is low.

In addition, because rubber sleeve 6, heat-insulation layer 7, overcoat 8 all are the solid parcel one deck outsides within it of tightly stretching tight one by one, each layer contact closely, and because the outside overwhelming majority of storage body all has heat-insulation layer, its heat leakage is little, high insulating effect, and have only heating face localized heat release when using, thus its heat concentrate and the heat release time long.

This shows that the warm bag of this heat-storage is the desirable utensil of a kind of thermotherapy or heating usefulness, is the thing of family and extremely frigid zones personnel's indispensability.
