Abstract
The utility model relates to a self-limiting temperature heating pad which is characterized in that a Archimedes spiral line groove is arranged on a foam plastic bottom pad, a PTC companion heating wire is arranged in the Archimedes spiral line groove, and two ends of the wire is enclosed with the epoxy resin; the outer end of the PTC companion heating wire is connected with the socket of the power supply; an upper cover plate is arranged on the upper part of the heating pad and stuck to the upper intercepting surface of the foam plastic bottom pad. The utility model has the advantages that: the heating element of the heating pad is self-limiting temperature PTC companion heating wire which doesn't need any temperature controller and other protection layers like burn-resistant, insulative materials. The heating at the temperature can simply be realized by choosing PTC companion heating wire with appropriate temperature; the PTC heating wire is simple in structure, economical and convenient as well as safe and reliable.
Description
Technical field
The utility model relates to a kind of heating resistance pad, can realize from the heating of limit temperature.
Background technology
At present domestic heating resistance pad all is to adopt heating element such as resistance wire to carry out electric heating, must have temperature regulating device simultaneously, also will have fire-retardant, insulating protective layer.
Use from limitting warm electric heating element, the heating that does not need to add any temperature regulating device is paid somebody's debt and expected repayment later not to be had.
Summary of the invention
The purpose of this utility model provides a kind of use and does not need the limit certainly of temperature regulating device temperature heating resistance pad from limitting warm heating element PTC companion hot line to heat.
For achieving the above object, the utility model is realized by the following technical solutions:
From the warm heating resistance pad of limit, it is characterized in that: be provided with spiral of Archimedes shape groove on the foamed plastics heelpiece, PTC companion hot line is arranged in the spiral of Archimedes shape groove both ends epoxy encapsulation; Outer end at PTC companion hot line is connected with supply socket; Be provided with upper cover plate on the top of heating resistance pad and foamed plastics heelpiece top interface is bonding.
Described upper cover plate is to make with thin plastics or rubbery flexible sheet.
The utility model has the advantages that: the heating element of this heating resistance pad is for from the PTC of limit temperature companion hot line, it does not need protective layers such as thermostat and other are fire-retardant, insulating material.As long as select the PTC companion hot line of suitable temperature, can realize the heating under this temperature; Simple in structure, economical convenient, safe and reliable.
Description of drawings
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the vertical view of the utility model structure.
Embodiment
Certainly limit warm heating resistance pad to elaborate to the utility model below:
See Fig. 1, Fig. 2, be provided with spiral of Archimedes shape groove 7 on foamed plastics heelpiece 8, PTC companion hot line 2 is arranged in the spiral of Archimedes shape groove 7, and both ends encapsulate with epoxy resin 9,6; Outer end at PTC companion hot line 2 is connected with supply socket 5; Be provided with upper cover plate 1 on the top of heating resistance pad bonding with foamed plastics heelpiece top interface 3, upper cover plate is made with thin plastics or rubbery flexible sheet, the connector lug 4 of PTC companion hot line welds admittedly with scolding tin with the terminals of supply socket 5, and uses the epoxy resin embedding, and the outside is good with the thermoplastic bobbin seal.
When the warm heating resistance pad of limit uses, when inserting the attaching plug of alternating current 220V, 50Hz in the supply socket 5, can heat.Because PTC companion hot line is the auto-temperature-limiting character with positive temperature coefficient, need not any thermostat, can keep the dispatch from the factory rated temperature of regulation of PTC companion hot line voluntarily.According to the temperature and the power requirement that use, selected PTC companion's hot line kind and length.
Described from limitting warm heating resistance pad, can be made into Any shape.
Claims (2)
1, limit warm heating resistance pad certainly, it is characterized in that: be provided with spiral of Archimedes shape groove on the foamed plastics heelpiece, PTC companion hot line is arranged in the spiral of Archimedes shape groove both ends epoxy encapsulation; Outer end at PTC companion hot line is connected with supply socket; Be provided with upper cover plate on the top of heating resistance pad and foamed plastics heelpiece top interface is bonding.
2, according to claim 1 from limitting warm heating resistance pad, it is characterized in that: described upper cover plate is to make with thin plastics or rubbery flexible sheet.
