Description
Technical field
The present invention relates to the electric warm water bag technical field, especially a kind of hot-water bag of embedded with safety type double-helical heating wire.
Background technology
China's utility model patent number: ZL200320120843.2 discloses a kind of " soft electric warm water bag ", and its Granted publication number is: CN2665572Y, and Granted publication day: on December 22nd, 2004; The electric warm water bag of this structure comprises a bag body, socket cover, seal receptacle, heating wire and liquid injection hole, also is provided with the high-resistance heating wire of low temperature that power density is not more than 50 watts/meter in the said bag body, and this heating wire is agglomerating or overlap agglomerating.The electric warm water bag of said structure, through heating wire to the intravital liquid heat of bag.But; 1), the electric warm water bag of this structure there is following weak point in the electric warm water bag of said structure:; Adopted common heating wire as electrical heating elements, this heating wire is agglomerating or overlap agglomeratingly with irregular form, and directly is placed on the bag inner chamber to liquid heat; Because bag is a flexible instrument, the flexural strength of heating wire is very low, and the easy deformation of its pressurized influences the heats of bag, even causes damage; Moreover the heating wire that is wound in bulk also causes easily and gets loose; 2), used the electric warming bag of this heating wire, do not reach the purpose of temperature control completely; 3), heating wire twines the big position of density and is heated higherly in the bag, heating wire twines the little position of density and is heated lowlyer, and it is unbalanced to cause bag integral body to be heated; 4), to heating wire be twined agglomerating or is overlapped to form bulk, its troublesome poeration.
For addressing the aforementioned drawbacks, the applicant has proposed a name not long ago and has been called " electric warming bag of built-in Double helix heating wire ", and application number is: 200720057333.3 Chinese utility model patent; Its structure comprises the bag with bag chamber; Bag is provided with electric control gear; Said bag intracavity is equiped with the Double helix heating wire, and the Double helix heating wire comprises mandrel, internal layer PTC spiral resistance wire, NTC heat-sensitive layer, outer spiral resistance wire and external insulation layer respectively by innermost layer to outermost layer; The Double helix heating wire is electrically connected with electric control gear.This hot-water bag is through being provided with the Double helix heating wire as independent electrical heating elements in bag, it is very high that it has a flexural strength, is difficult for the advantage of pressurized deformation; Moreover, because the Double helix heating wire has the double grading of PTC spiral resistance wire and NTC heat-sensitive layer, can realize the bag effect of temperature control completely, help its integral body and receive thermal balance.But still there is following weak point in the electric warm water bag of said structure: electric warming bag only depends on the Double helix heating wire as electrical heating element, influenced by Double helix heating wire self-characteristic; That is: the Double helix heating wire auto-cutout of being heated easily realizes protective effect; And the electric warm water bag inner chamber can have higher temperature when heating, and therefore, the hot-water bag of this structure is extremely unstable when heating, receives bag intracavity temperatures involved easily and open circuit protection.
Summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned prior art, and provide a kind of simple and reasonable for structure, the hot-water bag of the embedded with safety type double-helical heating wire that heating is safe, stable.
The objective of the invention is to realize like this:
A kind of hot-water bag of embedded with safety type double-helical heating wire; Comprise bag with bag chamber; Bag is provided with electric control gear, and the bag intracavity is equiped with the electric heating body that is electrically connected with electric control gear, and the bag intracavity is provided with the safety type double-helical heating wire that is electrically connected with electric control gear.The hot-water bag of this structure; Through being provided with the safety type double-helical heating wire at the bag intracavity; Make itself and electric heating body constitute electrical heating elements jointly, utilize of the difunctional effect of safety type double-helical heating wire, add heat stability and safety with the integral body that improves electrical heating elements as insurance and heating.
The object of the invention can also adopt following technical measures to solve:
As embodiment more specifically: said electric heating body can be heating wire, electrode, PTC electric heating part, electric heating tube or other electric heating body, and electric heating body and safety type double-helical heating wire are formed electrical heating elements jointly.
Said safety type double-helical heating wire and electric heating body are parallel and are connected on the electric control gear, that is: safety type double-helical heating wire and electric heating body constitute independently electric heating part separately.
As improvement further, said safety type double-helical heating wire and electric heating body are hung the upper and lower bag wall at the bag intracavity through lead respectively.
Said safety type double-helical heating wire also can be arranged on electric heating body then outward, and with said electric heating body certain distance is arranged.
Said safety type double-helical heating wire is wrapped on the radiator, helps the fixing of safety type double-helical heating wire, and improves its radiating effect.
Said safety type double-helical heating wire comprises mandrel, internal layer PTC spiral resistance wire, NTC heat-sensitive layer, outer spiral resistance wire and external insulation layer respectively by innermost layer to outermost layer.The Double helix heating wire of this structure, its mandrel play fixedly internal layer PTC spiral resistance wire effect; Internal layer PTC spiral resistance wire has ptc characteristics, that is: PTC positive temperature coefficient, and high more its resistivity of temperature is big more, can export temperature variant signal in real time; The NTC heat-sensitive layer has the NTC characteristic, that is: NTC negative temperature coefficient, and high more its resistivity of temperature is more little, can export temperature variant signal in real time equally; It has been heating function that outer spiral resistance wire mainly acts on; And external insulation layer mainly is the insulating effect that electrifies.
The invention has the beneficial effects as follows:
1), this structure electric warm water bag; Adopted the safety type double-helical heating wire with PTC and NTC characteristic to combine with electric heating body, constituted the electrical heating elements of hot-water bag jointly, its specific embodiment is; Safety type double-helical heating wire and electric heating body are parallel form to be connected on the electric control gear; Therefore, the safety type double-helical heating wire also has the effect of overtemperature protection except that having heat effect; When the Double helix insurance heating wire open circuit protection that is heated; Electric heating body still can continue heating work, and the whole heating power of bag is decreased, until bag intracavity heating-up temperature to setting value; Electric heating body just stops heating; Therefore, the electric warm water bag of this structure has simple and reasonable for structure, and safe, the stable effect of heating;
2), hot-water bag of the present invention, can also be through safety type double-helical heating wire and electric heating body be hung the upper and lower bag wall at the bag intracavity through lead respectively; Or directly the safety type double-helical heating wire is arranged on electric heating body then outward, and certain distance is arranged with said electric heating body; The hot-water bag of this structure utilizes the principle of expanded by heating, realizes the dual function of its heating, insurance effectively.
