Abstract
The utility model relates to a low voltage and timing power supply electric blanket capable of cutting power when man leaves. The electric blanket comprises a power line (1), an electric blanket body (2), a timing discontinuity controller (3), a step-down transformer (4), a relay (5), and a plurality of micro switches (6). The timing discontinuity controller (3) is respectively connected with the power line (1) and the step-down transformer (4). A heat coil (21) and a normally open contact of the relay (5) are connected in series and positioned between output ends of the step-down transformer (4). The micro switches (6) are connected in parallel and installed on the electric blanket body (2). The parallel installed micro switches (6) and a power supply end of the relay (5) are connected in series and arranged between the output ends of the step-down transformer (4). The safe low voltage power supply is utilized in the heat coil of the electric blanket, so that a user does not get an electric shock even though electric leakage happens. Power can be cut off automatically when man leaves, and therefore fire is not prone to be caused and use security is good. Timing interval power supply is utilized in the electric blanket, so that temperature controlling and temperature adjusting are convenient and the electric blanket is convenient to use.
Description
Technical field
The utility model relates to electric blanket, is specifically related to a kind of electric blanket that adopts safe low voltage power supply.
Background technology
Electric blanket is commonly called as electric mattress, and the operating voltage of common electric blanket heating wire is an alternating current 220V, does not belong to safe voltage, causes the user to get an electric shock easily if electric leakage takes place, and has certain danger.The people leaves and can not cut off the power supply automatically during this electric blanket power connection, leaves for a long time and forget to close power switch or pull up the easy initiation fire of plug, uses safety inadequately.
Summary of the invention
The purpose of the utility model provides that a kind of heating wire adopts that safe low voltage power supply, electric leakage can not cause that the user gets an electric shock, the people leaves and can cut off the power supply, be not easy initiation fire, low pressure timing power supply safe in utilization automatically from people's electric blanket that cuts off the power supply.
The technical solution of the utility model is: it comprises that an end is provided with the power line and the electric blanket blanket body that heating wire is installed of attaching plug; It also comprises can the manual adjustments power-on time be interrupted controller, reducing transformer, relay and several microswitches with the timing of the time of stopping power supply; The input that regularly is interrupted controller is connected with the other end that power line is provided with plug; The output that regularly is interrupted controller links to each other with the high voltage input terminal of reducing transformer; Heating wire on the electric blanket blanket body be connected between the low-voltage output of reducing transformer after the normally opened contact of relay is contacted mutually; Each microswitch mutually and connect and disperse respectively and be installed on the electric blanket blanket body, each microswitch of Xiang Binglian be connected between the low-voltage output of reducing transformer after the relay power end is contacted mutually.
The technique effect of the utility model is: the heating wire of this electric blanket adopts safe low voltage power supply; Even electric leakage can not cause the user to get an electric shock yet; The people leaves not turn off power source switch or pull up plug also can cut off the power supply automatically, is not easy initiation fire, and safety in utilization is good.It adopts regularly intermittent mode power supply, and temperature control and temperature adjustment are more convenient, is more convenient for using.
