Abstract
The utility model relates to an atomizer circuit, which comprises a power module, a voltage division module and an ultrasonator module, wherein the power module, the voltage division module and the ultrasonator module are sequentially connected. The atomizer circuit is characterized by further comprising a temperature detection module and a control module which are connected between the power module and the voltage division module, wherein the control module is used for controlling the working state of the ultrasonator module according to temperature signals fed back through the temperature detection module. The atomizer circuit has the advantages as follows: since the temperature detection module and the control module are additionally provided, the control module can control the working state of the ultrasonator module according to temperature signals fed back through the temperature detection module, the phenomenon of dry burning can be detected at any time, and the ultrasonator module can be timely cut off at the first time when the phenomenon of dry burning happens. The atomizer circuit is simple in structure and is safer for use.
Description
Technical field:
The utility model relates to a kind of atomizer circuit.
Background technology:
Fig. 1 is existing atomizer circuit structure diagram, this atomizer main circuit will comprise power module, division module and ultrasonator module, the ultrasonator module is vibrated with supersonic frequency by driving its high frequency piezoelectric ceramic sheet TD, the water that contacts with high frequency piezoelectric ceramic sheet TD is intensified by liquid state be micron order gaseous state fine particle, floating faling apart in the air reaches and beautifies the environment or improve the purpose such as air humidity.The situation of dry combustion method appears for preventing that atomizer from working long hours; traditional way be adopt dry-reed tube switch add the floating mode of magnetic as level control switch for water to realize the purpose without water conservation; but; because the water box of atomizer is in long-term use procedure; can produce incrustation scale unavoidably; this incrustation scale may cause that magnetic is floating can not to be changed with SEA LEVEL VARIATION, and then causes dry combustion method.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure, atomizer circuit of using safety.
A kind of atomizer circuit, comprise the power module, division module and the ultrasonator module that connect successively, it is characterized in that: also comprise the temperature detecting module and the control module that are connected between power module and the division module, control module is according to the duty of the temperature signal control ultrasonator module of temperature detecting module feedback.
A kind of improvement as such scheme, described temperature detecting module comprises the mutual resistance R that is connected in series 5 and the negative tempperature coefficient thermistor of being located at power end and earth terminal, described control module is PNP triode Q2, its base stage is connected between resistance R 5 and the negative tempperature coefficient thermistor, grounded collector, emitter stage then are connected with division module.
Further improvement as such scheme, described control module also comprises NPN triode Q3, the base stage of this NPN triode Q3 is connected with the colelctor electrode of PNP triode Q2 and by a bypass capacitor C 6 ground connection, the colelctor electrode of NPN triode Q3 is connected with the base stage of PNP triode Q2, the grounded emitter of NPN triode Q3.
The utlity model has following advantage: because have additional temperature detecting module and control module, so control module is according to the duty of the temperature signal control ultrasonator module of temperature detecting module feedback, can detect at any time and the dry combustion method phenomenon whether occur, and in the timely ultrasonator module that disconnects of the very first time that the dry combustion method phenomenon occurs, simple in structure, use safer.
Description of drawings:
Fig. 1 is existing atomizer circuit structure diagram.
Fig. 2 is the circuit structure diagram of the utility model embodiment one.

Embodiment two, as shown in Figure 3, be with embodiment one difference, described control module also comprises NPN triode Q3, the base stage of this NPN triode Q3 is connected with the colelctor electrode of PNP triode Q2 and by a capacitor C 6 ground connection, the colelctor electrode of NPN triode Q3 is connected with the base stage of PNP triode Q2, the grounded emitter of NPN triode Q3.
The above is preferred embodiment of the present utility model only, is not to limit the scope that the utility model is implemented, and all equal variation and modifications of doing according to the utility model claim all fall into the scope that the utility model patent contains.
