Abstract
A safety electric blanket comprises an electric blanket (1), wherein a plurality of piezoresistors (2) are arranged in a circuit on the electric blanket (1) on a main area for bearing a human body of a bed. The safety electric blanket has the advantages that: by utilizing the property that resistance values of the piezoresistors increase along with the increase of pressure, current in the circuit is reduced almost to zero, so as to avoid continuous heating of the electric blanket after people fall asleep. The safety electric blanket has simple structure, is very convenient to use, and is especially suitable for the edged, children and other crowds with low immunity to use.
Description
Technical field
The utility model relates to the daily living article technical field, a kind of specifically safety electric blanket.
Background technology
The electric blanket of people's use now is converted into heat energy with electric energy, for people provide the needed by human body heat, is subjected to people's favor; After but people were sleeping, if continue to use electric blanket, its temperature can not change, and so easy initiation dry skin, got angry, and seriously also can cause fire, brought unnecessary trouble.
The utility model content
The purpose of this utility model is a kind of safety electric blanket that can cut off the power supply automatically after the people is sleeping of design.
The utility model safety electric blanket comprises: electric blanket 1 in electric blanket 1 circuit of human bearing's main region, is provided with a plurality of piezo-resistances 2 in bed.
The advantage of the utility model safety electric blanket is: utilize piezo-resistance to increase and the characteristic of resistance value increase with pressure, make that electric current reduces almost nil in the circuit, avoid the sleeping back of people electric blanket persistent fever, simple in structure, use very conveniently, be particularly suitable for the low crowd of immunity such as old man, child and use.
Description of drawings
Fig. 1 is the structural representation of safety electric blanket.
The specific embodiment
According to shown in Figure 1, a kind of safety electric blanket comprises: electric blanket 1 in electric blanket 1 circuit of human bearing's main region, is provided with a plurality of piezo-resistances 2 in bed.
Claims (1)
1. safety electric blanket, comprising: electric blanket (1) is characterized in that: in the electric blanket of human bearing's main region (1) circuit, be provided with a plurality of piezo-resistances (2) in bed.
