Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0018] The invention provides a PTC heater device for eliminating induction electricity. The device forms a shielding effect through an induction electricity protection layer coated on the outside of the PTC heater, so that the potential difference between the zero line and the live line connected to the PTC heater It is zero, avoiding the situation of induction electricity. This device effectively solves the problem that the PTC heater is easy to generate induction electricity and has a large safety hazard when it is used on a product with a relatively humid working environment.

The invention discloses a PTC (Positive Temperature Coefficient) heater device capable of eliminating conductive current. According to the PTC heater device, a conductive current protection layer is coated at the outer side of a PTC heater, and aluminium foil paper of the conductive current protection layer is in contact with a second electrode plate of the PTC heater and is isolated from a first electrode plate of the PTC heater through insulated gummed paper; the conductive current protection layer forms a shielding layer effect and can be used for shielding a zero line which is connected with the second electrode plate and has lower potential; a high potential firing wire connected with the first electrode plate is wrapped in the shielding layer; the outer layer of the shielding layer is unipotential with the zero line; and an insulation layer is arranged between the shielding layer and an external aluminum heat-dissipating part and used for insulating the shielding layer and the external aluminum heat-dissipating part, so that the surface potential of the aluminum heat-dissipating part is approximately equal to the ground potential. Compared with the prior art, the PTC heater device disclosed by the invention has the advantages of good effect of eliminating conductive current, high safety and the like.
Description
technical field [0001] The invention belongs to the technical field of heaters in the field of electric heating, specifically a PTC heater, more specifically a PTC heater device for eliminating induction electricity, and belongs to a heating device used on a foot bath. Background technique [0002] PTC heating element is a new type of heating element with insulation and constant temperature. Two metal sheets are pasted on both sides of the PTC heating element, and two wires are used as electrified electrodes. No additional temperature control device is required. It has sustainable heating, safe and reliable. , stable power, and wide operating voltage, are widely used in various electrical appliances such as foot baths, hair stylers, hair straighteners, and facial beauty steam generators. [0003] The current PTC heaters are basically composed of a PTC heating element and a metal aluminum radiator with a hollow structure. The aluminum radiator includes two basically parallel ...
