Abstract
The utility model discloses a PTC piezoelectric ceramic element for titanium alloy electrode, comprising a PTC piezoelectric ceramic sheet, a nickel electrode, and a titanium alloy electrode. The PTC piezoelectric ceramic sheet is plated with the nickel electrode which is plated with the titanium alloy electrode. The utility model not only maintains the advantages of the PTC piezoelectric ceramic element for nickel electrode, but also has the obvious effects of oxidation resistance and little change of resistance through voltage impulse testing for service life, Thereby, the utility model can be widely used in warm air blower, dryer, electric radiator, dish drier, and hand drier, etc.
Description
The utility model relates to a kind of titanium alloy electrode PTC piezo ceramic element that is used for heating electrical equipment such as warm-air drier, dryer, electric heater, dish drier and hand drier.
By the effect of PTC piezo ceramic element characteristic, can heating, temperature control, current-limiting protection.This is well-known technology.Yet, because the condition of work difference has different influences to the PTC piezoelectric element.Generally influence less to the PTC piezo ceramic element in low-voltage, low temperature, small-power, and in high voltage, high-temperature, high-power work down, because after the repeated stock of high temperature, high voltage, big electric current, electrode resistance changes overproof easy oxide etch and bursts apart etc., and effect of PTC piezo ceramic element and useful life are had a strong impact on.At present, PTC piezoelectric ceramic element of Ni electrode, although reactance voltage impact and on useful life more original aluminium add silver (Al+Ag) electrode PTC piezo ceramic element large increase arranged, in high voltage, high-power impact, the high temperature oxidation and corrosion aspect does not also reach gratifying degree.
The purpose of this utility model provide a kind of on the PTC piezoelectric ceramic element of Ni electrode basis improved titanium alloy electrode PTC piezo ceramic element, it can prevent high voltage, powerful impact effectively, the high temperature oxidation and corrosion electrode, thus useful life of PTC piezo ceramic element prolonged effectively.
The purpose of this utility model is achieved in that a kind of titanium alloy electrode PTC piezo ceramic element of the electrical equipment that is used to generate heat, comprise PTC piezoelectric ceramic piece, nickel electrode and titanium alloy electrode, plated nickel electrode on the PTC piezoelectric ceramic piece adds the titanizing alloy electrode on nickel electrode.
The utility model is because only need add the titanizing alloy on PTC piezoelectric ceramic element of Ni electrode, so structure is simple especially, because titanium alloy resistance to oxidation corrosion, resistance decreasing behind voltge surge, so titanium alloy added is plated in the utility model that forms on the PTC piezoelectric ceramic element of Ni electrode, the advantage that had both kept PTC piezoelectric ceramic element of Ni electrode, to have strengthened high voltage withstanding, the powerful impact characteristics of electrode resistance to oxidation burn into, use the requirement in field thereby satisfied the PTC piezo ceramic element.
Concrete structure of the present utility model is provided by accompanying drawing.
Fig. 1 is the structure cutaway view of the utility model titanium alloy electrode PTC piezo ceramic element.
In Fig. 1, titanium alloy electrode PTC piezo ceramic element comprises PTC piezoelectric ceramic piece 1, nickel electrode 2 and titanium alloy electrode 3, and plated nickel electrode 2 on PTC piezoelectric ceramic piece 1 adds titanizing alloy electrode 3 on nickel electrode 2.
