Abstract
The utility model discloses a working state promoter for an electrical appliance. For the existing heater for vehicles and heating appliances for family, such as an electric cooker, an electric kettle and the like, a user can not be told by prompt sound when the work is over, therefore, the use is inconvenient. The working state promoter for the electrical appliance comprises a power supply (1) which is connected with a controller (2), the controller is connected with a voice chip (3) and a signal detecting device (4), and the voice chip is connected with a horn (5). The working state promoter is used for industry and daily life.
Description
Technical field:
The utility model relates to a kind of novel voice prompting device, is specifically related to a kind of electrical work condition prompting device.
Background technology:
The present auto heater and the electric heating appliance of family as electric cooker, electric kettle etc., when end-of-job, all do not have prompt tone to tell the user, use very inconvenient like this.When giving the automobile preheating and using electric cooker, electric kettle heated food and water, the time all must be chosen and nearby be guarded mostly, uses very inconvenient.
Summary of the invention:
The purpose of this utility model provides a kind of work that utilizes voice prompting device to point out the user to do and has finished, and brings great convenience to the user, and has saved the time.
Above-mentioned purpose realizes by following technical scheme:
Electrical work condition prompting device, its composition comprises: power supply, described power supply connects controller, and described controller connects speech chip and signal supervisory instrument, and described speech chip connects loudspeaker.
Described electrical work condition prompting device, described controller comprises current transformer or tongue tube, described current transformer or tongue tube connect resistance R 8, described resistance R 8 parallel resistance R7, described resistance R 8 and resistance R 7 series connection commutator tube IN4007, described resistance R 7 shunt capacitance C12, described capacitor C 12 connects triode Q3, described connection triode Q3 connects resistance R R1, and described resistance R R1 connects speech chip U1.
Described electrical work condition prompting device, described power supply comprises the 220V AC power, and described 220V AC power connects transformer, and described transformer is output as the 3-5V direct supply.
Beneficial effect:
1. the utility model makes things convenient for the client, makes the client in the indoor duty of promptly knowing auto heater, the convenient use.
2. the utility model can carry out fault judgement to vehicle preheater, gives the speech chip energized, if loudspeaker do not have prompt tone, illustrative system is in off state.
3. the utility model can be reminded the performance of the work that the user did of using this product at any time, and heating is still cooked, heated up water and all need not guard at any time to automobile, and the prompt tone of this product is given people's cordiality, warm sensation.
The utility model energy-conservation, safe, effective, be quick on the draw, react fast, cost is low, practicality good.
Description of drawings:
Accompanying drawing 1 is a structured flowchart of the present utility model.
Accompanying drawing 2 is circuit diagrams of the present utility model.
Accompanying drawing 3 is circuit diagrams of the speech chip of accompanying drawing 2.
Embodiment:
Embodiment 1:
Electrical work condition prompting device, its composition comprises: power supply 1, described power supply 1 connects controller 2, and described controller 2 connects speech chip 3 and signal supervisory instrument 4, and described speech chip 4 connects loudspeaker 5.
Described electrical work condition prompting device, described controller comprises current transformer or tongue tube, described current transformer or tongue tube connect resistance R 8, described resistance R 8 parallel resistance R7, described resistance R 8 and resistance R 7 series connection commutator tube IN4007, described resistance R 7 shunt capacitance C12, described capacitor C 12 connects triode Q3, described connection triode Q3 connects resistance R R1, described resistance R R1 connects speech chip U1, and described speech chip U1 comprises speech chip U1-2 and speech chip U1-7.
Embodiment 2:
Embodiment 3:
When the consumer deenergization, current transformer does not detect signal, makes triode Q3 be in cut-off state, thereby makes speech chip U1-2 end form high level and trigger speech chip once more, makes it carry out the voice suggestion second time.
Resistance R R1 is the pull-up resistor of triode Q3, when triode Q3 conducting, the electric current resistance R R1 that flows through is arranged, thereby form voltage drop on RR1, and speech chip U1-2 end is low level with respect to positive source speech chip U1-7 end; When triode Q3 by the time, do not have the electric current resistance R R1 that flows through, thereby on RR1, can not form voltage drop, speech chip U1-2 end is equipotential with respect to positive source U1-7 end, is high level.Thereby the whether conducting of triode Q3 directly controls the current potential of speech chip U1-2, also just controlled the voice suggestion of speech chip.
Resistance R 7, resistance R 8 are fictitious load, and be steady in order to guarantee the detected signal of current transformer.
The part that (comprises capacitor C 6) before the condenser capacitance C6 is a Switching Power Supply, for control circuit and sound circuit provide direct-current working volts stably.
