In prior art, heating rod is generally with glass tube encapsulation, regulates temperature by mechanical knob.But this series products existing also exists a lot of drawback, first power-off is forgotten changing in water process, heating rod dry combustion method is made to cause heating rod to burst due to few water like this, and then cause security incident, it does not possess solid structure, be easy to damage or corroded, also can form certain potential safety hazard to personal safety.Secondly, to the control underaction of temperature, be not easy to regulate, dry combustion method, overtemperature often occur and not to cut off etc. and damage thus cause user to lose; Although also have some electronic products to have controller carry out set temperature but not there is dried up function of automatically cutting off.In addition, can be subject to a great extent managing the impact of interior hot-air on the measurement of temperature in prior art, lose due accuracy.
Utility model content
The disappearance that the utility model exists for prior art, its main purpose is to provide a kind of condenser type water level detecting heating rod.
For achieving the above object, the utility model condenser type water level detecting heating rod comprises upper cover and heating rod main body, described heating rod main body comprises the closed canals of stilling in front end, the side of described canals of stilling is provided with thermal insulation board, in described canals of stilling, be provided with heating wire and control board, described heating wire electricity is connected in described control board; Described upper cover top is provided with thermoregulation knob, and described thermoregulation knob electricity is connected in described control board;
Have pcb board in described thermal insulation board arranged outside, described pcb board is arranged at bottom described thermal insulation board, is upwards evenly provided with some conducting surfaces at described pcb board from bottom;
Also comprise plastic septum, described plastic septum is arranged at outside described pcb board, has temperature sensor in described plastic septum arranged outside, and described temperature sensor electricity is connected in described control board.
Further, between described heating wire and control board, heat insulation is provided with.
Further, described control board is provided with display screen.
Further, described upper lid surface is provided with protective sleeve.
Further, described temperature sensor is arranged in the middle part of described plastic septum.
Beneficial effect: 1. heating rod of the present utility model is according to the principle of capacitance type touch control keys, all can there is capacitance, and the capacitance of water is much larger than the capacitance of air, applies this theoretical principle and carry out sensed water level between any material.When heating rod inserts in water, when water arrives the conducting surface on pcb board, a capacitance can be produced at water, plastic septum, conducting surface place, control board reads this capacitance and judges that whether this capacitance is capacitance when having water, thus conclude whether pcb board has been in water state, namely detect heating rod and whether be in afloat condition, the heater strip that control board can control heating rod stops heating, and the dried up dry combustion method of heating rod can be avoided to cause situation about damaging.Meanwhile, pcb board is evenly provided with several conducting surfaces, just can measures multiple water level.2. there is temperature sensor in plastic septum arranged outside, temperature sensor is arranged in the middle part of plastic septum, be provided with thermal insulation board between the position that temperature sensor is arranged and heating source heating wire, reduce heating wire to the impact of measuring sample, add the accuracy of temperature detection.In addition, heating-up temperature can also be pre-set by thermoregulation knob, the temperature arranged and Real-Time Monitoring temperature show by display screen, automatically reduce heating wire power when temperature is near set temperature and carry out mild heat, lower until cut off completely when arriving set temperature the closer to power, adopt extremely low power to maintain set temperature afterwards, excess temperature heat damage heating rod can be avoided.
