The utility model discloses a medium temperature silver thick liquid preparation resistance to milliohm level side hinders thick liquids, utilizes linear close check resistance, and medium temperature sintering obtains required resistance, does the insulating layer with low temperature resin type printing ink, and the preparation is convenient, and is with low costs, the high efficiency, and long service life, temperature coefficient is little.
Description
Technical field
The utility model belongs to electric mosquito repellent liquid heater, is specially temperature in one and makes thick film ceramic mosquito repellent fever tablet.
Background technology
Existing electric mosquito repellent liquid heater, general use resistance wire or PTC sheet, resistance wire power consumption is large, and the life-span is short.PTC sheet, cost of manufacture is high, and material is leaded many, not environmentally.A kind of cost of manufacture of the utility model is low, and resistance control range is few, the thick film mosquito-repellent incense liquid heater of long service life.
Prior art, on alumina substrate, temperature silver slurry and middle temperature linear resistance slurry in printing, then with intermediate sintering temperature, obtain stable resistive layer, then print the resin insulating barrier of 280 degree, layer on resistive layer surface.
Utility model content
The purpose of this utility model is to provide temperature in one to make thick film ceramic mosquito repellent fever tablet, and solve existing mosquito-repellent incense heater or consume energy high, the life-span is short, or cost of manufacture is high, leaded problem not environmentally.
The utility model realizes by the following technical solutions:
In one, temperature makes thick film ceramic mosquito repellent fever tablet, and comprise ceramic substrate, galactic pole, resistive layer and insulating barrier, described galactic pole is embedded on ceramic chip, and described galactic pole end is connected with resistive layer, and resistive layer is fixed on a ceramic substrate by described insulating barrier.
In the utility model, the thickness of described ceramic substrate is 1 ㎜.
In the utility model, described resistive layer is ring-type.
In the utility model, the width of described resistive layer is 0.5 ㎜.
In the utility model, described insulating barrier covers resistive layer top.
Beneficial effect: during the utility model adopts, temperature silver slurry makes resistance, and with milliohm level sheet resistance slurry, utilize the strict controlling resistance of linear, intermediate sintering temperature obtains required resistance, do insulating barrier with low-temperature resins type ink, easy to make, cost is low, high efficiency, long service life, temperature coefficient is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, a kind of middle temperature makes the structural representation of thick film ceramic mosquito repellent fever tablet, a kind of thick film electric mosquito repellent liquid heater, comprise ceramic substrate 1, galactic pole 2, resistive layer 3 and insulating barrier 4, described galactic pole 2 is embedded on ceramic chip 1, described galactic pole 2 end is connected with resistive layer 3, resistive layer 3 is fixed on ceramic substrate 1 by described insulating barrier 4, the thickness of described ceramic substrate 1 is 1 ㎜, described resistive layer 3 is ring-type, the width of described resistive layer 3 is 0.5 ㎜, and described insulating barrier 4 covers resistive layer 3 top.
During preparation, thick be 1 ㎜ ceramic substrate 1 surface print galactic pole 2, galactic pole 2 adopt in temperature silver slurry, adopt infrared drying stove dry, bake out temperature controls at 150 DEG C, and drying time controls at 30 minutes; Printed resistor layer 3, warm resistance slurry during resistive layer 3 adopts, be communicated with galactic pole 2, and adopt infrared drying stove to dry, bake out temperature controls at 150 DEG C, and drying time controls at 30 minutes; Adopt thick film firing stove, roasting temperature 580 DEG C, is incubated 10 minutes; Print insulating barrier 4 at resistive layer 3 again, adopt infrared oven, roasting in-furnace temperature controls at 280 DEG C, and baking oven time controling, at 30 minutes, forms insulating barrier 4; Utilize digital electric bridge test resistance to be 4.5 Europe, error is ± 5%; At galactic pole 2, place leads to 5V direct current, and ceramic substrate 1 can reach 100-105 DEG C in 1 minute, thus reaches heating volatilization mosquito-repellent incense liquid, reaches to repelling effect.
In the utility model, utilize the middle temperature resistance slurry of milliohm level sheet resistance, printing wide is the line image of 0.5 ㎜, to reach precise hard_drawn tuhes resistance, utilizes intermediate sintering temperature simultaneously, can reduce greatly sintering cost; Adopt thick-film technique, greatly can improve heat utilization ratio, promote service life.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and specification just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
