Description

A kind of safety heater with the kenel sealed

The utility model relates to electric type, particularly a kind of safety heater with the kenel sealed.

Progress along with society, various electric property heaters are a lot, the advanced person is for well with the ceramic resistor material, spontaneous thermostatic control of its body of mat and flames of anger state and on the Secure Application Pan Ju important seat is arranged, this body is flat form, two of negative and positive are the electrode guiding access, also be the main surface of emission of heat wave simultaneously, because this body body is short and small, the heat energy of being launched, all need to exchange out its heat energy by carrier, and this carrier generally adopts the preferable metal material formation of conductive coefficient to have the form of radiating fin, use in conjunction with the PTC body, use and obtain effectively band heat exchange energy, and above-mentioned combining form, two of PTC body negative and positive, indivedual interface applying carriers, and its applying power need rely on the vertical external force maintenance in other opposites, must set up by other members relatively, could be effectively fixing, again after the combination, this heating element body is outer dewiness, unfavorable wet environment is used, and more because this body is a flat, positive and negative electrode is positioned at two of negative and positive, if there is erratic current to pour, then can produce creepage corona in the body side, take place to jump electric spark danger, the state that this spark jeopardized has clothes drying machine or hot warmer etc. can accumulate the clothing cotton-wool, or the utensil of inflammable batt fiber, after taking place to jump electric spark, it is on fire promptly to ignite, and still is a big shortcoming of using.

Main purpose of the present utility model is exactly at above-mentioned shortcoming, and a kind of safety heater with the kenel sealed is provided, and reaches the security protection of effective electric property, and more deep layer Secure Application is provided in the use.

Technical conceive of the present utility model:

According to the purpose of this utility model, a kind of safety heater with the kenel sealed is provided, its structure is by an elongated tubular encapsulated member, body is formed with two crimping faces, connects into a circular bar by two distortion sides, inner crimping ceramic resistor PTC heating monomer between relatively, can be dissipated by the heat exchange of heat dissipation element band in the outside, the effective crimping of this encapsulated member of mat and seal effect exposes and intercept electric power, and the danger of the creepage phenomenon that forms when preventing to transship.
