Abstract
The utility model relates to an electric safety fast-heating tap, which is a tap using electricity for heating. The utility model is composed of a casing, a water inlet, a water outlet, conducting wires, a silicon nitride heating element, a handle and a water switch. The handle is arranged on the water inlet. The water inlet is arranged on one end of the casing and the water outlet is arranged on the other end of the casing. The silicon nitride heating element is arranged in the casing and sealed by a press plate and screws. The conducting wires are connected with the silicon nitride heating element. The utility model has the advantages of simple structural design, small size, safety, reliability, long service life, electricity saving and optimum heating temperature, and the electric safety fast-heating tap is especially suitable for being arranged on the taps of families and public places.
Description
The Instant heating type water tap of the utility model Electrical Safety type belongs to field of electric heating, particularly a kind of electrically heated water tap of using of silicon nitride heat generating body that adopts.
The conventional electric heating water heating device generally is to adopt the resistance wire heating, this mode exists working life short, the problem of poor stability, needs are used the hot water occasion continuously,, be not suitable for adopting as water tap, heating to the water discharge of water faucet in the daily life, require safe and reliablely, keep water temperature when solid stream of water, volume will match with water tap.Owing to adopt the resistance wire heating, can not reach requirement, the use of electric heating water tap is subjected to bigger restriction.
The purpose of this utility model is to avoid the deficiencies in the prior art part, and provides a kind of safe and reliable, keeps water temperature when solid stream of water, and volume is little, and is safe and reliable, long service life, power saving, the Instant heating type water tap of safety type of employing silicon nitride heat generating body.
The purpose of this utility model reaches by following measure, it is that silicon nitride heat generating body is set in flow channel, adopt silicon nitride heat generating body in the process that current pass through, make the mode of water heating realize heating, it is by housing, water intake, water outlet, lead, silicon nitride heat generating body, handle, hydraulic pressure switch is formed, in the water inlet handle is installed, water intake is at an end of housing, and water outlet is provided with silicon nitride heat generating body at the other end of housing in the housing, by pressing plate, the screw sealing, lead links to each other with silicon nitride heat generating body, and silicon nitride heat generating body is by tungsten filament, and molybdenum filament and silicon nitride matrix are formed, tungsten filament is as heating source, molybdenum filament is as extraction pole, and tungsten filament connects molybdenum filament, tungsten filament, molybdenum filament is placed in the silicon nitride matrix, the diameter of tungsten filament and molybdenum filament is 0.01-0.5mm, tungsten filament connects molybdenum filament and is placed in the silicon nitride matrix, because the heating effect of silicon nitride heat generating body is good, when current are in housing, the silicon nitride heat generating body of heating power heats water, because water intake is at an end of upper shell, water outlet is at an end of lower shell body, and the time that current are retained in housing is long, in the process of flowing through heating time long, can keep the temperature of water outlet.In use just in case damage, silicon nitride heat generating body itself has automatic insulation characterisitic to silicon nitride heat generating body, and is safe and reliable.
A hydraulic pressure switch is set on housing, realizes hydraulic pressure control.
Little TRIP is set on electrified wire.
The utility model structural design is simple, and volume is little, and is safe and reliable, long service life, and power saving, heating-up temperature is suitable, is particularly suitable for being installed on the water tap of family and public place using.
Accompanying drawing 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model is by housing 1, water intake 3, water outlet 10, lead 6, silicon nitride heat generating body 9, handle 2, hydraulic pressure switch 8, pressing plate 4, little TRIP 7 is formed, in the water inlet handle is installed, water intake is at an end of housing, and water outlet is provided with silicon nitride heat generating body at the other end of housing in the housing, by pressing plate, screw 5 sealings, lead links to each other with the extraction pole of silicon nitride heat generating body, and a hydraulic pressure switch is set on housing, realizes hydraulic pressure control, little TRIP is set on electrified wire, the silicon nitride heat generating body of heating power heats water, and water enters the back and flows along silicon nitride heat generating body, flows out from water outlet.
