Abstract
The utility model discloses an electric blanket having automatic on-off function, wherein an automatic control unit is added on the basis of the existing electric blanket, and comprises a single chip module, a temperature sensor, a pressure sensor, a relay circuit and a power supply circuit, wherein the pressure sensor is arranged within the electric blanket; the temperature sensor is used for sensing the room temperature; the pressure sensor and the temperature sensor both are connected to the single chip module; the relay circuit functions as the power-on switch of the electric blanket and is controlled by the single chip module; and the power supply circuit supplies power to the automatic control unit. The utility model realizes intelligent automatic control of the electric blanket, and is more convenient for use; and simultaneously, the safety of use is improved.
Description
Technical field
The utility model relates to a kind of electric blanket with auto-switch function.
Background technology
Electric blanket is one of heating product of using always winter, and its heat production speed is fast, efficient is high, low price, becomes good sleep partner in the house in winter.
Electric blanket mainly is through the heating wire heat production, and long-time energising then has potential safety hazard if forget shutoff after electric blanket uses, and initiation fire causes personnel and property loss easily, and this case is not within minority.So be necessary to design a kind of safe electric blanket, make the relieved use of people's ability.
The utility model content
The utility model is directed against the problem in the background technology, and proposes a kind of electric blanket with auto-switch function.
This electric blanket is in existing electric blanket, to have increased automatic control unit, and this automatic control unit is used to realize electric blanket energising and outage automatically.
Said automatic control unit comprises one-chip computer module, temperature sensor, pressure sensor, relay circuit and power module; Wherein: pressure sensor is arranged in the electric blanket; Temperature sensor is used for senses room temperature, and pressure sensor all is connected one-chip computer module with temperature sensor, and relay circuit acts on the power-on switch of electric blanket; Relay circuit is controlled by one-chip computer module, and power module is used for supplying power to automatic control unit.
Preferably, power module adopts No. 5 powered battery of two joints.
Technique effect:
1, the sensor control technology is combined with the relay technology, realized the auto-switch function of electric blanket, improved the safety in utilization of electric blanket.
2, simple in structure, reasonable in design, realize easily.
3, meet the Smart Home idea of development, guide is provided for intelligentized life direction.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
The specific embodiment
Be described further in the face of the utility model down.
The structure of the utility model electric blanket is as shown in Figure 1, and it is on the basis of existing electric blanket, to improve, and has increased automatic control unit, to realize the automatic energising and the power down function of electric blanket.
Said automatic control unit comprises one-chip computer module, temperature sensor, pressure sensor, relay circuit and power module; Wherein: pressure sensor is arranged in the electric blanket; Temperature sensor is used for senses room temperature, and pressure sensor all is connected one-chip computer module with temperature sensor, and relay circuit acts on the power-on switch of electric blanket; Relay circuit is controlled by one-chip computer module, and power module is used for supplying power to automatic control unit.
Single-chip microcomputer adopts the AT89C51 efficient microprocessor of atmel corp; Temperature sensor adopts the SRA-T indoor temperature transmitter; Pressure sensor adopts piezoresistive pressure sensor; Power module adopts No. 5 powered battery of two joints.
Temperature sensor is responded to indoor temperature in real time, when pressure sensor sense the human pressure, when indoor temperature is lower than setting value, the Single-chip Controlling relay circuit makes the electric blanket power-on switch open energising, the electric blanket heat production.When pressure sensor influence electricity signal or indoor temperature were higher than setting value, the Single-chip Controlling relay circuit broke off power-on switch, and electric blanket is cut off the power supply automatically.
