Description
Technical field
The utility model is related to daily life tools field more particularly to a kind of electric appliance temperature pre-warning systems.
Background technology
It is the excessively high initiation of short-circuit temperature mostly because the accident that electric appliance causes is more and more with popularizing for household electrical appliance
Burning or explosion accident, such as mobile phone explosion accident in recent years occurred it is a lot of, therefore electric appliance use when safety problem need
It draws attention.
Invention content
The purpose of this utility model is to provide a kind of electric appliance temperature pre-warning system, the monitoring temperature when electric appliance uses, excessively high
It can alarm and automatically power off, improve the safety that electric appliance uses.
Following technical scheme may be used to realize in the technical issues of the utility model solves：
A kind of electric appliance temperature pre-warning system, it is characterised in that：It is shown including alarm plug, temperature sensor and LED temperature
Show device, shown alarm plug is inserted on external conventional electrical socket, equipped with ON-OFF control circuit, restorer, socket plug, confession
Electrical outlet and loudspeaker, the socket plug connect external receptacle, and described is the connectivity port of appliance plug for electrical outlet, described to open
Close the inside that control circuit is located at alarm plug, control power supply output；The alarm plug connects temperature by communication line
Spend sensor.
Preferably, the temperature sensor shape is blocky for strip, and the LED temperature display is arranged on temperature sensor
Top center, inside has circuit to be connect with temperature sensor.
Preferably, the temperature sensor is equipped with background light.
The utility model collects electric appliance temperature signal by temperature sensor, is sending out short report by loudspeaker when the temperature is excessively high
It is alert, it is automatically disconnected the circuit in temperature danger, and equipped with LED temperature display, thermometer use, volume can be done when not charging
It is small, it is simple in structure, greatly improve the safety of electric appliance.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the circuit module schematic diagram of the utility model.
In figure, 1- alarms plug, 2- temperature sensors, 3- LED temperatures display, 11- ON-OFF control circuits, 12-
Restorer, 13- socket plugs, 14- are for electrical outlet, 15- loudspeaker.
Specific embodiment
The utility model is described in further detail with reference to embodiment, but the embodiment of the utility model is not
It is limited to this.
Such as the preferred embodiment that Fig. 1,2 are the utility model, shown including alarm plug 1, temperature sensor 2 and LED temperature
Show device 3.
Alarm plug 1 is inserted on external common socket, as the central socket of appliance plug, is set on alarm plug 1
Have ON-OFF control circuit 11, restorer 12, socket plug 13, for electrical outlet 14 and loudspeaker 15, socket plug 13 connects external insert
Seat, is the connectivity port of appliance plug for electrical outlet 14, and the ON-OFF control circuit 11 is located at the inside of alarm plug, control
Power supply exports, and loudspeaker 15 send out short alarm when the temperature is excessively high, and temperature danger duration alarms and disconnects output circuit.Temperature is returned
Restart to charge to restorer 12 can be pressed during normal condition.
Alarm plug 1 connects temperature sensor 2 by communication line, and temperature sensor 2 is the receipts of electric appliance temperature signal
Acquisition means, shape is blocky for strip, for measuring electric appliance temperature, using being with electricity measurer is wanted to contact installation by temperature sensor 2
.While LED temperature display 3 is provided with, LED temperature display 3 is arranged on the top of temperature sensor 2 in the present embodiment
Center, inside have circuit to be connect with temperature sensor 2, conveniently check the temperature of display.The back of the body can be set on temperature sensor 2
Scape lamp.LED temperature display 3 may also be arranged on alarm plug 1, as long as facilitate the position of display.
As shown in Fig. 2, restorer 12 passes through circuit controlled horn 15, socket plug 13, temperature sensor 2 and LED temperature
Display 3, temperature sensor 2 send signal control restorer 12 and bounce simultaneously.
The workflow of the utility model is as follows（Assuming that electric appliance temperature is safe range below 60 DEG C）：
1) for plugging appliance plug in electrical outlet 14, restorer 12 is depressed, and the external receptacle that socket plug 13 connects is opened
It closes and opens；
2) temperature sensor 2 is leaned against on electric appliance, makes temperature sensor 2 and relay contacts, the energization of temperature sensor 2 is opened
Beginning work, alarm plug 1 can be powered；
3) temperature sensor 2 collects temperature signal, when temperature is below 60 DEG C, 3 displays temperature of LED temperature display；Temperature
When between 60 DEG C~80 DEG C, background light reddens 3 displays temperature of LED temperature display degree simultaneously, 15 of short duration alarm of loudspeaker；
4) when temperature is more than 80 DEG C, restorer 12 bounces disconnection, 15 long alarm of loudspeaker；Socket plug 13 connects simultaneously
External receptacle switch disconnect, appliance plug power-off；Temperature sensor 2 powers off, and is stopped；
5) when temperature returns to normal condition, restorer 12 is depressed manually, restorer 12 resets, and stops alarm, and socket is inserted
The external receptacle switch of first 13 connection is opened.
The above is only the utility model preferred embodiment, not the technical scope of the utility model is appointed
What is limited, thus every technical spirit according to the present invention above example is made any trickle amendment, equivalent variations are with repairing
Decorations, still fall within the scope of protection of the utility model.
