Abstract
The utility model provides an alarm for the untight closing circumstance of a refrigerator door. The alarm is characterized in that the alarm is integrated in a box body, and the box body is placed in a refrigerator. The interior of the box body is connected with a photosensitive probe through a wire, and the photosensitive probe is arranged at a door lamp of the refrigerator. The edge of a cold storage door and the edge of a freezing door are respectively connected with a thin-film jogging probe in a sticky mode, and the two thin-film jogging probes are connected into the box body through wires. A photoresistor is arranged in the photosensitive probe, and thin-film microswitches which are connected in parallel are arranged in the two thin-film jogging probes. The alarm in the box body is composed of a protective resistor, a Schmitt trigger, a diode, a relay, a voice integrated module and a buzzer. The alarm for the untight closing circumstance of the refrigerator door is simple in structure and capable of facilitating transformation of an existing refrigerator; the photoresistor is matched with the thin-film microswitches, sensitivity is high, and random alarming due to erroneous judgment can be avoided; the whole alarm is low in price, the box body is made of heat-preservation materials, and the alarm for the untight closing circumstance of the refrigerator door is suitable for transformation of the existing refrigerator and capable of saving electric energy wasted when the door of the refrigerator is not tightly closed.

The described protective resistance dividing potential drop of connecting with photo resistance; positive source connects upper photo resistance one end; the other end of photo resistance connects Schmidt trigger input; Schmidt trigger output connects relay input; relay output end is connected with two film microswitches in parallel; film microswitch is connected successively with voice integration module, buzzer the negative pole of finally connecting with the mains and forms complete circuit loop, and diode is in parallel with relay.
Described box body is that insulation material is made.
Described relay is normally closed relay.
Described film microswitch is quick transfer contact switch.
Technique effect of the present utility model: simple in structure, can on existing refrigerator, reequip easily, photo resistance and film microswitch coordinate, highly sensitive, can not produce erroneous judgement reports to the police carelessly, the electronic component of circuit the inside is all very common, low price, whole alarm is cheap, box body adopts insulation material, can prevent that electronic component from reducing in the refrigerator inside life-span, increase the service life of alarm, further reduce the use cost of alarm, be applicable to existing refrigerator repacking, can save the electric energy that door of refrigerator closes waste when tight.
Accompanying drawing explanation
Fig. 1 is the utility model circuit theory schematic diagram;
Fig. 2 is the utility model overall structure schematic diagram.
Number in the figure represents respectively: 1-box body; 100-protective resistance, 101-Schmidt trigger, 102-diode; 103-relay; 104-voice integration module, 105-buzzer, 2-photosensitive probe; 201-photo resistance; 3-film Sensor for detecting small movemeats, 301,302-film microswitch, 4-wire.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in the figure, described a kind of door of refrigerator closes not tight alarm, it is characterized in that: alarm is integrated in box body 1, box body 1 is placed on refrigerator inside, in box body 1, by wire 4, connect photosensitive probe 2, photosensitive probe 2 is arranged on the gate light place of refrigerator, on the cold sotrage door of refrigerator and the limit of door of refrigerator, each adhesion has a film Sensor for detecting small movemeats 3, two film Sensor for detecting small movemeats 3 are connected in box body 1 by wire 4, in photosensitive probe 2, be provided with photo resistance 201, in two film Sensor for detecting small movemeats 3, be provided with film microswitch in parallel, alarm in box body 1 is by protective resistance 100, Schmidt trigger 101, diode 102, relay 103, voice integration module 104 and buzzer 105 form.
Described protective resistance 100 dividing potential drop of connecting with photo resistance 201; positive source connects upper photo resistance 201 one end; the other end of photo resistance 201 connects Schmidt trigger 101 inputs; Schmidt trigger 101 outputs connect relay 103 inputs; relay 103 outputs are connected with two film microswitches in parallel; film microswitch is connected successively with voice integration module 104, buzzer 105 negative pole of finally connecting with the mains and forms complete circuit loop, and diode 102 is in parallel with relay 103.
