Abstract
The utility model relates to a PTC heater which uses a PTC to carry out the temperature heating. When the Curie temperature or the external voltage has a change, the present temperature acquired by the PTC heating also has a change, so the actual use is affected; and when the external voltage is overhigh, the PTC heater is easy to damage. The PTC heater includes a PTC heating assembly. One end of the PTC heating assembly is provided with a supporting seat. The supporting seat is provided with a temperature controller and a fuse which are connected with the PTC heating assembly. The temperature controller is connected with a first joint via a lead. The outside of the fuse is provided with an insulating layer. The fuse is connected with a second joint via a lead. The PTC heater is simple in structure and is safe to use. When the external voltage is overhigh or the Curie temperature has a change, the damage of the PTC heater is prevented, and the PTC heater is safe and environmental friendly.
Description
Technical field
The utility model relates to the PTC heater that a kind of PTC of utilization carries out the temperature heating.
Background technology
The existing device that utilizes PTC to carry out the temperature heating, normally directly PTC is linked to each other with plug, then being directly connected to power supply heats, and the variation of PTC thermistor heating-up temperature is relevant with Curie temperature and applied voltage, and when Curie temperature or applied voltage changed, the temperature of utilizing PTC to heat also can be somebody's turn to do thereupon, the use that impact is actual, and, when applied voltage is excessive, also cause easily the damage of PTC heater.
