Head is connect with external electric-controlled plate；External water stream is flowed into from the water inlet tap of thick film heater ontology, by being heated when runner cavity
Route heating, then flowed out from faucet, utilize the water outlet thermistor temp and heating plate thermistor of thick film heater ontology
Temperature carries out intersection comparison, is determined as doing when heater thermistor temp value is than big 30 DEG C of thermistor temp value of water outlet or more
It burns, electric-controlled plate quickly identifies to carry out open circuit protection.
As an improvement, the runner cavity and heating line are S type curvilinear structures.
As an improvement, the leaving water temperature thermistor does the use of detection leaving water temperature apart from heating line 10-15mm
On the way.
As an improvement, the heater thermistor is examined apart from heating line 3-5mm close to the high-temperature region of heater
Survey the purposes of temperature of heating plate.
The advantages of the present invention over the prior art are that: it can be identified (see attached drawing within thick film heater dry combustion method 3 to 4 seconds
4), so that power-off is protected, the temperature of thick film heater is no more than 150 DEG C at this time, and safety is effectively protected；In thickness
When film heater works normally, since runner cavity has the presence of flowing water load, water outlet thermistor temp and heater heat
The temperature difference of quick resistance is no more than 25 DEG C, this dry combustion method guard method will not influence the normal work of heater.

Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, wherein the identical attached drawing mark of identical components
Note indicates, it should be noted that word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to
Direction in attached drawing, word "inner" and "outside" refer respectively to the direction towards or away from geometric center of specific component.
In order that the present invention can be more clearly and readily understood, following will be combined with the drawings in the embodiments of the present invention,
Technical scheme in the embodiment of the invention is clearly and completely described.
In conjunction with attached drawing 1-3, a kind of thick film heater, including thick film heater ontology 1, the thick film heater ontology 1
Inside is equipped with runner cavity 8, and is equipped with heating line 3, the runner cavity 8 along runner cavity 8 on thick film heater ontology 1
It is S type curvilinear structures with heating line 3, one end of runner cavity 8 is equipped with water inlet tap 6, and the other end is equipped with faucet 7, thick film
One end of heater body 1 is equipped with power connection 2, and close faucet 7 is equipped with leaving water temperature heat on the thick film heater ontology 1
Quick resistance 4, leaving water temperature thermistor 4 do the purposes of detection leaving water temperature apart from heating line 10-15mm, and the thick film adds
It is equipped with heater thermistor 5 close to heating line 3 on hot device ontology 1, heater thermistor 5 is apart from 3 3- of heating line
5mm does the purposes of detection temperature of heating plate, the leaving water temperature thermistor 4 and heater heat close to the high-temperature region of heater
Quick resistance 5 is connect by power connection 2 with external electric-controlled plate, water outlet thermistor temp 4 and heating using thick film heater
5 temperature of device thermistor carries out intersection comparison, when the temperature of leaving water temperature thermistor 4 is smaller than 5 temperature of heater thermistor
