Description
Technical field
The utility model relates to the heating field of daily life, particularly, relates to a kind of heater of adjustable heating-up temperature.
Background technology
At present; Known electric kettle be the sheet deformation that the water vapour that produces when utilizing water to boil makes the steam temperature-sensing element; And utilize distortion to promote mains switch through lever principle, thus electric kettle is cut off the power supply when water is boiled automatically, its outage can not reset; So outage back kettle can not heat automatically again, and the acquiescence heating-up temperature all is the temperature of boiling water.And need water be heated to boiling many in daily life the time, and cool off again as water being heated to boiling, just caused the waste of power resource.
Summary of the invention
The purpose of the utility model is, to the problems referred to above, proposes a kind of heater of adjustable heating-up temperature, to realize avoiding the advantage of power resource power resource waste.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of heater of adjustable heating-up temperature comprises temperature measurement circuit, heater circuit, push-button switch, display circuit and control circuit, and said temperature measurement circuit, heater circuit, push-button switch and display circuit are connected electrically on the control circuit respectively.
Further, the master chip of said control circuit adopts single-chip microcomputer.
Further, the heater of adjustable heating-up temperature also comprises DC power supply circuit, and said DC power supply circuit is electrically connected with temperature measurement circuit, heater circuit, display circuit, control circuit respectively.
Further, said DC power supply circuit comprises transformer TR1, rectifier bridge, filter capacitor C1, three terminal regulator U1 and capacitor C 2, and electric current flows to load through transformer TR1, rectifier bridge, filter capacitor C1, three terminal regulator U1 and capacitor C 2 successively.
The technical scheme of the utility model; Through temperature measurement circuit water temperature is measured, and be sent to control circuit to the water temperature signal of measuring, and show through display circuit; Thereby utilize the temperature that push-button switch is controlled flexibly needs heating, thereby practiced thrift a large amount of power resources.
Further feature of the utility model and advantage will be set forth in specification subsequently, and, partly from specification, become obvious, perhaps understand through implementing the utility model.The purpose of the utility model can realize through the structure that in the specification of being write, claims and accompanying drawing, is particularly pointed out and obtain with other advantages.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.
