Abstract
The utility model discloses a directly-heated type drinking water boiler heater based on microcrystalline glass. A heating resistive film is printed on a microcrystalline glass substrate which is dry pressed, the resistive film is annular, the turning corner of the resistive film is connected by a soldering point, an insulating film is covered on the resistive film and placed in a kiln for low-temperature baking (less than 800 DEG C), then an outer lead is soldered and riveted to form the directly-heated type drinking water boiler heater based on the microcrystalline glass, the outer lead is connected into a circuit, a power supply is on, and the resistive film can be heated to generate heat for heating the water in a container. The directly-heated type drinking water boiler heater can be widely applied to tea making water in the daily life.
Description
Technical field
The utility model relates to a kind of electric heater unit, especially a kind of electrical heating drinking water boiler heater by the devitrified glass substrate bears.
Background technology
At present, raising along with people's living standard, everybody is often have tea in life or the contacts at home together, and is also more and more exquisite to sampling tea, for making tea, the firstth, quality of tea leaves, be exactly being particular about of water then, outside dewatering, also extremely important to the mode of heating of water, its mode has following several: the one, heat with fuel combustion, it consumes energy high, and speed is slow and influence environment, and the 2nd, microwave and electromagnetism heating, though its speed is fast, but exist the width of cloth to penetrate, the 3rd, all kinds of electrical heating heater elements mainly contain the PTC ceramic heating element, heating wire, electrothermal tube, quartz ampoule etc., the utensil of these traditional heater element assemblings is because of the defective performance of heater itself, in market and application, be restricted gradually, as the PTC ceramic heating element, its thermal shock electric current is big, can only be processed into sheet, maximum operation (service) temperature is no more than 300 ℃, and exothermic material easily decays, and the element power decay is serious, contains a large amount of lead simultaneously, do not meet environmental requirement, heating process is too slow; Heating wire heating has naked light, easily strikes sparks during loose contact, arcing, produces potential safety hazard, and can not be applicable to occasions such as high humidity, high salt fog, and component life is short; Other heating element heater such as electrothermal tube, quartz ampoule etc., it is shaped as tubulose, can only be used for than the large space occasion.There is such or such defective in existing in a word these heating element heaters, have seriously influenced their application.
Summary of the invention
In order to overcome the deficiency of existing heating material and loading material, the utility model provides a kind of devitrified glass directly-heated drinking water boiler heater, this heater is quantity of heat given up directly, firing rate is fast, and do not contain or harmful element such as any heavy metal of indiffusion, human body there are not electromagnetism and microwave radiation yet.
The technical scheme that its technical problem that solves the utility model adopts is: at first print the heating resistor film on the circular crystallite glass substrate that dry-pressing makes, the resistive film shaped design circularizes, connect with tin welding spot in the resistive film corner, and then cover one deck dielectric film thereon, through the uniform temperature baking, weld the riveting lead-in wire again and just make devitrified glass directly-heated drinking water boiler heater.When power supply is received on its outside lead, the generation heat that promptly generates heat of the resistive film in it, heat becomes heater by crystallite glass substrate transmission output.
The beneficial effects of the utility model are: because the devitrified glass insulating properties are good, heating resistor film and air are isolated, not oxidation, so stable performance, long service life, no electromagnetism and microwave radiation, devitrified glass directly-heated drinking water boiler heater surfaces heating-up temperature is even simultaneously, thermal inertia is little, quick heating, so it is energy-efficient; Owing to microcrystal glass material dielectric strength height, volume resistance is big again, and thermal-shock resistance is good, so this devitrified glass directly-heated drinking water boiler heater is safe and reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 is a kind of devitrified glass directly-heated of the utility model drinking water boiler heater B-B cutaway view.
Fig. 2 is a kind of devitrified glass directly-heated of the utility model drinking water boiler heater A-A cutaway view.
Among the figure 1, crystallite glass substrate, 2, resistive film, 3, dielectric film, 4, outer lead 5, tin welding spot
The specific embodiment
As shown in the figure, go up the resistive film (2) that printing is used to generate heat at the crystallite glass substrate (1) that dry-pressing makes, the shaped design of resistive film (2) circularizes, and connects with tin welding spot (5) in the resistive film corner.Cover one deck dielectric film (3) more thereon, the kiln low-temperature bake (＜800 ℃) of packing into after coming out of the stove, is weldering riveting outer lead (4) again, during use outer lead (4) is connected with the mains, the resistive film (2) of this devitrified glass directly-heated drinking water boiler heater promptly generates heat and produces heat the water of container is heated.
Claims (2)
1. a devitrified glass directly-heated drinking water boiler heater is gone up printing heating resistor film (2) at crystallite glass substrate (1), and covers one deck dielectric film (3), and weldering riveting outer lead (4) is characterized in that: connect with tin welding spot (5) in resistive film (2) corner.
2. a kind of devitrified glass directly-heated drinking water boiler heater according to claim 1 is characterized in that: heating resistor film (2) be shaped as annular.
