Abstract
The utility model relates to the daily use article technical field, in particular to a safety electric-heating felt blanket, which is realized through the following technical proposal: a heating wire is fixed in the thermal insulated felt blanket, and a plurality of thermostats are connected in series with the heating wire. Each thermostat comprises a housing, a base and a bimetallic strip having different coefficients of thermal expansion, wherein, the bimetallic strip is arranged on the base; the upper contact of the bimetallic strip is fixed on one end of the bimetallic strip; the lower contact of the bimetallic strip is arranged below the upper contact and is fixed on the base, and the upper and lower contacts are connected with each other through a wiring pin. With the structure, two or more than two thermostats are connected with the heating wire, thus even if one of thermostat is damaged during use and can not break the circuit in case of a temperature beyond specification, other thermostats can continue to control the temperature, thereby greatly improving the safety performance of the electric-heating felt blanket.
Description
Technical field:
The utility model relates to the daily living article technical field, refers in particular to a kind of safe and reliable electric heating felt.
Background technology:
In the climate of cold, people often need use the electric heating felt to come warming health, particularly concerning some the elderlys or suffer from the people of rheumatism, rheumatoid disease its irreplaceable especially warming product.Its internal structure of electric heating felt commonly used at present is that heating wire is directly made on cloth, utilize cloth to support and fixing heating wire, and the heating temp by thermostat control heating wire, when the temperature of heating wire reaches certain value, thermostat will cut off the power supply of heating wire, drop to certain depth until its temperature, thermostat recloses the power supply of heating wire.Present thermostat generally is to utilize two kinds of different bimetal leafs of thermal coefficient of expansion to make.The disconnection or the closure of the deformation control circuit that produces when being heated by it.Though present electric heating felt has adopted a thermostat to control the temperature of electric heating felt, but can take place still that thermostat is the impaired or heating of electric heating felt is inhomogeneous to make the situation that thermostat can't operate as normal owing to people in use are not intended to, the temperature that causes the electric heating felt to produce is too high, even burning the electric heating felt, these all threaten user's safety of life and property.
Summary of the invention:
The purpose of this utility model is to provide a kind of safe and reliable electric heating felt.
The utility model is achieved by the following technical solution: heating wire is fixed in the heat insulation felt, and some thermostats are connected with heating wire, and place in the heat insulation felt.
Described thermostat comprises the bimetal leaf that shell, base and thermal coefficient of expansion are different, wherein bimetal leaf is installed on the base, and upper contact is fixed in an end of bimetal leaf, and lower contact places the below of upper contact, and be fixed on the base, upper and lower contact is connected with leg respectively.
After adopting this structure, two or more thermostats are connected with heating wire, even so in use there is a thermostat to damage, can't when heating wire temperature superelevation, circuit be disconnected, still have other thermostat can continue to control temperature, improved the security performance of electric heating felt greatly.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the front view of the utility model thermostat;
Fig. 3 is the cut-away view of the utility model thermostat.
Embodiment:
See accompanying drawing 1,2,3, the utility model comprises: comprising: heating wire 1 and heat insulation felt 2, heating wire 1 are fixed in the heat insulation felt 2, and some thermostats 3 are connected with heating wire 1.Described thermostat 3 comprises shell 31, base 32 bimetal leaf 33 different with thermal coefficient of expansion, wherein bimetal leaf 33 is installed on the shell 31, and upper contact 34 is fixed in an end of bimetal leaf 33, and lower contact 35 places the below of upper contact 34, and is fixed on the base 32.Upper and lower contact 34,35 is connected with leg 36 respectively, by leg 36 thermostat 3 and heating wire 1 is together in series.Thermostat 3 should be close to heating wire 1 in use, guarantees the stable of its work.
Be arranged with the airtight epidermis 4 of an employing PVC material on the heat insulation felt 2, the electric heating felt can play the function of protection against the tide, waterproof like this.
When using the utility model, energized at first, make heating wire 1 energising produce heat, when heating wire 1 arrives the temperature of appointment, bimetal leaf 33 is with expanded by heating in the thermostat 3, and the bimetal leaf 33 in the present embodiment slightly is bent downwardly at normal temperatures, upper and lower contact 34,35 is connected, and entire circuit is in closes and state.The coefficient of expansion of peripheral sheet metal is littler than interior sheet metal in the bimetal leaf, Wai Wei sheet metal is when the temperature that raises identical like this, and degrees of expansion is littler than interior sheet metal, causes whole bimetal leaf to be bent upwards, thereby make upper contact 34 and lower contact 35 disconnect, cause heating wire 1 to open circuit; When temperature dropped to certain value, the bimetal leaf in the thermostat 3 restored, and heating wire 1 conducting restarts heating.
Adopted two or more thermostats 3 to connect in the utility model with heating wire 1, even so in use there is 1 thermostat 1 to damage, can't when heating wire 1 temperature superelevation, circuit be disconnected, still have other thermostat can continue to control temperature, improve the security performance of electric heating felt greatly, effectively ensured user's safety of life and property.
