Abstract

An object of the utility model is to overcome prior art's defect, provide a novel anti-overflow goes out device, the device includes acoustoelectric transducer, amplifier and main control unit, and acoustoelectric transducer is connected with main control unit electricity through the amplifier. The acoustoelectric transducer and the amplifier are both in a resonant frequency-selective mode. When the liquid substance boils, sound waves with specific frequency are generated, the sound waves are converted into electric signals through the resonant frequency-selective acoustoelectric transducer, the electric signals are amplified through the resonant frequency-selective amplifier and then transmitted to the main controller, the main controller judges that the liquid substance is boiled, the power is automatically reduced or the power supply is cut off, the liquid substance immediately turns to a slight boiling or boiling stopping state, and the overflow of the liquid substance is effectively prevented. The utility model can be installed on any electric heating equipment and is suitable for any cooking or heating utensil, only by utilizing the sound wave with specific frequency generated when the liquid substance boils, thereby being not influenced by the change of air pressure. The utility model discloses simple structure, the stable performance, low in production cost, the anti-overflow effect is showing.

Description

A kind of anti-overflow device
Technical field
The utility model relates to a kind of anti-overflow device, especially relates to a kind of anti-overflow device of family expenses electric heating equipment.
Background technology
Raising along with the material life condition, increasing family has generally used various electric heating equipments, such as electric kettle, electric stove, electromagnetic oven, micro-wave oven, light-wave cooker, soy bean milk making machine, electric power make coffee mechanical, electrical iron pan, electric oven, electric oven or the like.These electric heating equipments are usually used in boiling water, heating milk or coffee or other beverage, boiling or cooking food.When water or beverage or other liquid were heated to boiling, high-temperature fluid overflowed easily, polluted and wasted, or cause the electric heating equipment short circuit and damage, even lead to security incident.
For preventing that liquid from overflowing, people have used schemes such as temperature sensing device or anti-spilled probe.But, temperature sensing device is usually only depressed at normal atmosphere and could be experienced fluid temperature more exactly and whether reach boiling point, if when climate change or height above sea level factor caused change of atmospheric pressure, boiling point of liquid changed, this moment, temperature sensing device will be malfunctioning; If use anti-spilled probe, must be in the cooking or heating vessel this kind of special configuration probe, promptly must use the special cooking or heating vessel, thereby limit its scope of application.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, a kind of influence that is not subjected to air pressure change is provided, and can be applicable to the anti-overflow device of any existing cooking or heating vessel.
For achieving the above object, the utility model adopts following technical scheme:
A kind of anti-overflow device, this device is made up of acoustic-electrical transducer, amplifier and master controller, and acoustic-electrical transducer is electrically connected with master controller through amplifier.
Described acoustic-electrical transducer is the resonant selecting frequency acoustic-electrical transducer.
Described amplifier is the resonant selecting frequency amplifier.
Described acoustic-electrical transducer is piezoelectric ceramic piece or microphone or loudspeaker or loudspeaker.
After adopting said structure, boiling appears when liquid is heated to boiling point, produce the sound wave of CF, the resonant selecting frequency acoustic-electrical transducer is responded to this sound wave, and converts acoustic energy to the signal of telecommunication, and the signal of telecommunication is sent to master controller after the resonant selecting frequency amplifier amplifies processing, master controller judges that liquid has reached boiling point, automatically reduce power immediately or cut off the electricity supply, liquid commentaries on classics place immediately gentle boil or defervescence state, thus effectively prevent overflowing of liquid.
The beneficial effects of the utility model are: only need utilize the sound wave of the CF that liquid produced when boiling, thereby not be subjected to the influence of air pressure change fully, this device can be installed on any electric heating equipment, and applicable to any cooking or heating vessel.The utility model is simple in structure, stable performance, and production cost is low, and the anti-overflow effect is remarkable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals:
The 1-acoustic-electrical transducer; The 2-amplifier; The 3-master controller; The 4-electric heating equipment; The 5-cooking utensil.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of anti-overflow device of the utility model is made up of acoustic-electrical transducer 1, amplifier 2, master controller 3, and acoustic-electrical transducer 1 is electrically connected with master controller 3 through amplifier 2.Acoustic-electrical transducer 1, amplifier 2 and master controller 3 are installed in the electric heating equipment 4.Cooking utensil 5 places on the electric heating equipment 4.Acoustic-electrical transducer 1 is positioned at cooking utensil 5 belows and close cooking utensil 5.Boiling appears when the liquid in the cooking utensil 5 is heated to boiling point by electric heating equipment 4, produce the sound wave of CF during boiling, after acoustic-electrical transducer 1 with resonant selecting frequency function is sensed the sound wave of CF, immediately acoustic energy is converted to the signal of telecommunication and be transferred to amplifier 2, the signal of telecommunication is transferred to master controller 3 again after amplifier 2 amplifies processing, boiling has appearred in master controller 3 judgements, automatically reduce the power of electric heating equipment 4 immediately or cut off the electricity supply, liquid commentaries on classics place immediately gentle boil or defervescence state, thus overflowing of liquid prevented effectively.
What this specification was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under operation principle of the present utility model and thinking all are considered as protection domain of the present utility model.
