【Specific implementation mode】
The invention will be further described below in conjunction with the accompanying drawings：
A kind of instant heating type tap with burning prevention function as shown in Figures 1 to 5, including leading shell 31, it is described
In leading shell 31 equipped with it is hollow and for for flow inside it by heating tube 32, the heating tube 32 and power supply electricity
It connects and the water inside it will be flowed through when being powered and heat, pre- water inlet flow channel 372 and water inlet are additionally provided in the tap shell 31
Runner 373,373 one end of the water inlet flow channel are connected to 32 one end of heating tube, and the tap shell 31 is equipped with and heating tube 32
The depotition cock 34 that the other end is connected, described 372 one end of pre- water inlet flow channel are connected to water supply pipe, the pre- water inlet flow channel
The two can be connected to and can be held in a short time when outside is cut off the water supply by being equipped between 373 other end of 372 other ends and water inlet flow channel
Continue and supplies water to prevent the anti-dry burning device of 32 dry combustion method of heating tube, flow from entering pre- water inlet from water supply pipe to water inlet flow channel 373
Runner 372 after first passing through anti-dry burning device water outlet, then through water inlet flow channel 373 flows to heating tube 32, and from 32 other end of heating tube
Depotition cock 34 is flowed to, when water supply pipe is cut off the water supply, anti-dry burning device can continue to supply water to heating tube 32, play time-lag action,
It is reacted for heating tube 32 and is stopped and sets aside some time, while contribute to heating tube 32 is quickly cooled down cooling, effectively prevents
The phenomenon that heating tube 32 works and damages in the absence of water has the characteristics that safe and reliable.
The anti-dry burning device includes the anti-dry water storage case 381 for being set to 32 top of heating tube, the anti-dry water storage case
381 water inlets are connect with the upper port of pre- water inlet flow channel 372, on 381 water outlet of anti-dry water storage case and water inlet flow channel 373
Port connects so that and the flow of feed pipe flows to heating tube 32 through water inlet flow channel 373 again after first passing through anti-dry water storage case 381,
Flow, which first flows into, carries out corresponding water storage in anti-dry water storage case 381, heating tube 32 is flowed to again later, when water supply pipe is cut off the water supply
When, the interior water stored of anti-dry water storage case 381 can then continue to supply water to heating tube, and in addition anti-dry water storage case 381 is higher than heating
Pipe 32, when cutting off the water supply, the water level in anti-dry water storage case 381 is higher than heating tube 32, and flow can flow down automatically, simple in structure.
Being equipped between the water supply pipe and pre- water inlet flow channel 372 can prevent the flow in pre- water inlet flow channel 372 from flowing backwards
Unidirectional pipe valve 382 so that when cutting off the water supply, the flow in anti-dry water storage case 381 flows back in pre- water inlet flow channel 372, anti-dry
Reliability is high.
Since heating tube 32 is hollow form, internal a portion as water flow circuits, 32 outside of the heating tube
It is coated with heat-insulation and heat-preservation set 37, heat loss caused by heating tube 32 can be effectively prevent, there is simple in structure, energy conservation and environmental protection
The characteristics of；The pre- water inlet flow channel 372 and water inlet flow channel 373 are located in heat-insulation and heat-preservation set 37, heat-insulation and heat-preservation set 37 it is absorbable from
The heat that heating tube 32 comes out, and the flow by water stream channel is tentatively preheated, flow into heating tube 32 again later
Interior to be heated immediately by preset temperature, therefore, the heating tube 32 of smaller power, which can be used, to be carried out, and reduce using circuit
Requirement, energy-saving effect is more preferable, is allowed to more adaptability.
The heat-insulation and heat-preservation set 37 is made of silica gel, convenient for sealing grafting with pipeline.
The pre- water inlet flow channel 372 and water inlet flow channel 373 are the integrated molding hole of heat-insulation and heat-preservation set 37, the heat-insulation and heat-preservation

374 one end of water outlet sprue is connected to heating tube 32, is led between 374 other end of water outlet sprue and hot water effluent road 375
Flow divider and pipeline connection are crossed, the other end in the hot water effluent road 375 is connected to by pipeline with depotition cock 34, by that will go out
Water sprue 374 first connects flow divider, then by piping connection hot water effluent road 375, then has and supply heat to depotition cock 34
While water, it is also an option that giving other device provisioning hot water, meet different demands, versatility is good.It is flowed out in heating tube 32
Hot water flows to flow divider by water outlet sprue 374, and one of Zhi Liujing hot water effluents road 375 flows to out the fire hose after shunting
First 34.
In addition, the hot water after heated flows through water outlet sprue 374 and hot water effluent road 375, heat-insulation and heat-preservation set 37 can incite somebody to action
It is discharged the heat absorption that sprue 374 and hot water effluent road 375 distribute and in pre- water inlet flow channel 372 and water inlet flow channel 373
Flow is preheated, and heat is utilized effectively, more energy conservation and environmental protection.
The pre- water inlet flow channel 372, water inlet flow channel 373, water outlet sprue 374 and hot water effluent road 375 are heat-insulation and heat-preservation
The integrated molding hole of set 37, it is simple in structure, it is easy to produce and process, save pre- water inlet flow channel 372, water inlet flow channel 373, water outlet mainstream
The assembling procedure of the pipe fitting related to hot water effluent road 375 of road 374.Can also be as needed, by individual economizer bank as flow
Channel is equipped with the corresponding groove for fixing economizer bank in 37 inside of heat-insulation and heat-preservation set, which is then posted by heating tube
Economizer bank can also be fixed in heat-insulation and heat-preservation set 37 by 32 lateral walls in other ways.
In addition, water outlet sprue 374 and hot water effluent road 375 be located at heat-insulation and heat-preservation set 37 in, it is heated after hot water stream
Through being discharged sprue 374 and hot water effluent road 375, heat-insulation and heat-preservation set 37 can dissipate water outlet sprue 374 and hot water effluent road 375
The heat absorption of hair simultaneously preheats the flow in pre- water inlet flow channel 372 and water inlet flow channel 373, and heat is utilized effectively.
The lower end of the water inlet flow channel 373 is connected to the lower end of heating tube 32, the upper end of the heating tube 32 with
Be discharged the upper end connection of sprue 374 so that when heating, flow from bottom to top, so as to preferably will be out of heating tube
The water flowed through heats immediately.
32 lower end of the heating tube and upper end are respectively provided with the lower seal 391 for sealing heating tube 32 and upper sealing
The sealing ring that can be sleeved on 32 port of heating tube is protruding in part 392, the lower seal 391 and upper seal 392 respectively
390, convenient for being tightly connected with 32 both ends of heating tube, it is respectively equipped with and can sticks on down on the peripheral surface of the heat-insulation and heat-preservation set 37
Gasket 376 on sealing element 391 and upper seal 392, the gasket 376 are equipped with for compressing simultaneously gasket 376
