Background technology
In the prior art, human body be used for the heating service device have varied, from initial filling hot-water type hot water bag, excessively arrive iron-clad electric heating cake, but the both exists many defectives, as irritating the hot-water type hot water bag, when each the use, all necessary hot water of preparing in advance is when needing liter steady after water temperature descends, must reheat water again, after the use, also the water in the bag to be emitted troublesome poeration and waste resource, also cause the scald accident easily, use safety inadequately; Iron-clad electric heating cake, quality is heavy, carries inconvenience, the temperature after heating extra-high-speed, rapid heat dissipation during use, the metal surface is too hard, the feel discomfort, reliability is relatively low, and costs an arm and a leg.Therefore, human body is used for heating installation and is progressively replaced by electric hot-water bag.
Existing commercially available electric hot-water bag, shell is generally used two of nylon taffetas, the edge is through the sealing water storage bag of thermal synthesis different shape, fill water or electrolyte in the bag, be placed with two heating electrodes in the bag, heating electrode is communicated with power supply plug-in unit on being located at water storage bag outer surface, wherein also is in series with temperature detect switch (TDS) between heating electrode and the power supply plug-in unit.After energized, the glassware for drinking water between two heating electrodes has certain resistance, and water changes electric energy into heat energy as load, heat energy is absorbed by water and stores, and when water temperature reached limiting temperature, temperature detect switch (TDS) can be cut off the electricity supply automatically, finish a work process, electric hot-water bag promptly can be used as the usefulness of heating.The Kick type temperature detect switch (TDS) that the temperature of electric hot-water bag control at present adopts bimetal leaf to constitute, the temperature detect switch (TDS) temperature-controlled precision is poor, and electric hot-water bag can produce a certain amount of gas in heating process, in case temperature detect switch (TDS) lost efficacy can't deenergization the time, electric hot-water bag can be because heat time heating time be long, and the interior gas of bag constantly increases, it is big that pressure becomes, can make the electric hot-water bag explosion, cause the accident, safety can't ensure.
Summary of the invention
This utility model provides a kind of simple in structure in order to solve the weak point that above-mentioned prior art exists, and uses more safe and reliable safety electric water bag.
For achieving the above object, this utility model adopts following scheme: a kind of safety electric hot water bag, include the water storage bag, conducting electrolyte in the water storage bag, be soaked in the insulating support of an end edge and the heat seal of water storage bag sealing in the electrolyte, be arranged on power connector and the heating electrode on the insulating support and be connected on temperature detect switch (TDS) in the power circuit, described temperature detect switch (TDS) includes the pedestal that is located in the insulating support, be arranged on the static contact and the movable contact spring that are communicated with metal electrode film respectively in the pedestal, be installed in the Kick type bimetal leaf on the pedestal and the top cover of pedestal, between bimetal leaf and movable contact spring, be provided with catch bar, and catch bar one end and bimetal leaf surface close neighbour, the other end and movable contact spring surface close neighbour, offer the opening that bimetal leaf is exposed on the pedestal top cover, sealing is provided with elastica on the top cover opening.
This utility model further is set to: be provided with boss in the elastica inboard with respect to the bimetal leaf place, raised head face and bimetal leaf surface close neighbour.
The beneficial effects of the utility model are: this utility model is compared with original technology, by on the pedestal top cover of temperature detect switch (TDS), offering the opening that the bimetal leaf jut is exposed, sealing is provided with elastica on the top cover opening, on the one hand, utilize the bimetal leaf sensitivity of temperature to external world on the temperature detect switch (TDS), auto power off came control water temperature after electrolyte in the water storage bag reached limiting temperature, on the other hand, for preventing to lose efficacy or sensitivity when descending at temperature detect switch (TDS), electrolyte is long heat time heating time, cause the explosion of water storage bag, cause the accident, and utilize the pressure that gas produces in the bag, and act directly on the bimetal leaf that exposes by elastica, promote the purpose that bimetal leaf reaches the auto power off control water temperature.This internal structure layout arrangement is reasonable, has improved security performance greatly, uses safelyr, reliable, has improved service life.
Below in conjunction with embodiment and accompanying drawing this utility model is further specified.
