Thick membrane heating device and electrothermal product using the same

The utility model provides a thick membrane heating device and an electrothermal product using the same, comprising a base material and a thick film heating circuit printed on the base material; the base material consists of a flexible metal base material or a flexible nonmetal base material; the thick film heating circuit is provided with connection terminals connected to a DC power supply device. Compared with the prior art, the thick film heating device adopts the DC power to work and thus the electrothermal products using the thick film heating device can operate by breaking away from a wired power supply and is portable; because the electrothermal product adopts low voltage direct current, the safety is guaranteed; and the adopted flexible base material is applicable to the heated objects with various curved surface, the capability of resisting deformation is strong and the service life is long. The utility model also provides the electrothermal products of the heating decie, like immersion suits, constant temperature sofas, electrothermal mats and vacuum cups.
