Description
Technical field
The utility model relates to a kind of electric hot-water bag, refers in particular to a kind of electric hot-water bag with explosion prevention function.
Background technology
Electric hot-water bag extensively gets consumer reception because of the advantage that easy to use, temperature retention time is long, heating effect is good etc.Present common electric hot-water bag, its structure roughly comprises the sealing bag that a usefulness PVC nylon taffeta is made, be provided with two clavate heating electrodes in the bag, be electrically connected with the electrical socket that is positioned at the hot-water bottle surface, after the energized, just begun because the liquid volume in the bag is less, bag is more flat, this moment, positive electrode rod and negative electrode rod were immersed in below the liquid simultaneously, by the positive electrode rod, the negative electrode rod, the circuit pathways that electrical socket and power supply are formed is given the liquid heat in the bag, with the increase of heating time, bag and reaches automatic limit temperature by attemperating unit and prevents the superheated purpose of electric hot-water bag under liquid volume and steam constantly expand and expand and heave.But because the length basically identical of present its positive and negative electrode rod of electric hot-water bag structure, and the positive and negative electrode rod generally is in the same level Position Design, if attemperating unit is malfunctioning like this, the after-tack of being heated of two heating electrode rods is sagging, make the positive and negative electrode rod can not break away from conducting medium solution, cause the electric hot-water bag over-heating easily, finally cause the electric hot-water bag explosion phenomenon.
Therefore in order to increase the fail safe that electric hot-water bag uses, can in electric hot-water bag, design blast resistance construction.Be in the patent case of CN 2820143Y, CN1925700 disclosing of blast resistance construction to be arranged all as publication number.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of explosion-proof electric hot-water bag that is different from the prior art structure will be provided, and it can cut off the power supply under the situation of electric hot-water bag excessive expansion automatically, and reliable in action, makes that the safety in utilization of electric hot-water bag is better.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this explosion-proof electric hot-water bag, include software water storage bag, conducting electrolyte in the water storage bag, insulating support with water storage bag heat seal sealing, be arranged on the power connector and just on the insulating support, negative heating electrode and be connected on attemperating unit in the power circuit, it is characterized in that having extended first tube connector and second tube connector on the position up and down of insulating support being positioned at, and the length of first tube connector below being positioned at is greater than the length of second tube connector of top, just, negative electrode is fixedly arranged on respectively on two tube connectors, and is electrically connected with power connector after passing separately tube connector by lead.
Described attemperating unit is arranged on the bottom of insulating support, and the root of described first tube connector and second tube connector is in the top of this attemperating unit.
Described first tube connector and second tube connector are tubular, the slightly downward heeling condition in the first tube connector place wherein, and the second tube connector place level.
Compared with prior art, advantage of the present utility model is after this electric hot-water bag energising heating, just begun because the liquor capacity in the bag is less, bag can be more flat, this moment just, below the conducting electrolyte in the negative electrode while infusion packet, by positive electrode, negative electrode, the circuit pathways that electrical socket and power supply are formed, just, negative electrode is given the liquid heat in the bag, increase with heating time, bag is under liquor capacity and steam constantly expand and expand and heave, along with driving insulating support, heaving of bag rise, the rising of insulating support is just then driving, negative electrode rises, and owing to just be used for setting firmly, the tube connector length difference of negative electrode, the tube connector that wherein is positioned at the below is longer, thereby soften with heat is sagging, and the tube connector that is positioned at the top is shorter, it is sagging to be not easy deliquescing relatively, like this after bag is heaved to a certain degree, that electrode that is positioned at the top can leave the liquid of bag earlier, by just, negative electrode, the circuit breaker that electrical socket and power supply are formed, just, negative electrode has also just stopped liquid heat, thereby employing said structure, it just can also play the purpose of limit temperature after losing efficacy when the attemperating unit on the electric hot-water bag, stoped the expansion of bag, guarantee safe handling and reliable in action, simple in structure, only need the Design of length of two tube connectors is become different just passable.
Description of drawings

Fig. 2 is the structural representation of the utility model embodiment under outage limit temperature state after the bag excessive expansion.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
In conjunction with Fig. 1, shown in Figure 2, the software water storage bag of this electric hot-water bag 1 adopts the PVC nylon taffeta to make, and bag body hollow can be made various difformities such as quincunx, pentagon.Be filled with conducting electrolyte 2 in the bag, generally with water as conducting electrolyte.Have a breach on bag, described insulating support 3 is located in the described breach and the heat seal sealing and fixing, and insulating support 3 is equipped with power connector and attemperating unit, and wherein attemperating unit is positioned at the bottommost of this insulating support inside.Electrical socket is contained in the top of insulating support 3, exposes to outside the bag.One extends two tubular tube connectors of arranging up and down and be positioned on the insulating support 3 of bag inside also, the length that wherein is positioned at first tube connector 6 of below will be much larger than the length of second tube connector 4 that is positioned at the top, and the slightly downward heeling condition in first tube connector, 6 places, and second tube connector, 4 place's levels.Described first tube connector 6 and second tube connector 4 are structure as a whole with insulating support 3, adopt resistant to elevated temperatures plastics to make.Positive electrode 5 and negative electrode 7 are fixedly arranged on two tube connectors, and are electrically connected with power connector after passing tube connector by lead, form power-on circuit by positive electrode, negative electrode, electrical socket and power supply, and attemperating unit is connected in the circuit.
