Abstract
The utility model discloses a multifunction clock-controlled automatic switch for electric appliances which is a self-controlled timing switch and takes advantage of the mainspring of a mechanical alarm clock to push a microswitch, making power supply switching can be in any time within twelve hours and simultaneously timedly automatically switch on or off two groups electric appliances. The utility model has the advantage of simple operation and make people' s life convenient.
Description
The utility model belongs to home-use electrical equipment time switch, is specially adapted to the electrical equipment that needs the time to control automatically.
Present small electric apparatus time switch on the market, one hour timing all can only be provided, as Chinese patent application, application number is 89213102.0 utility model " mechanical alarm clock of energy time switch power supply ", and its function is only ended " generally can keep power supply about a hour 20 minutes ".When needing the longer time regularly then can not be suitable for, as the timing of evening in summer to electric fan, one hour obviously is inadequate like this.
The purpose of this utility model provides and can implement timing automatic energized or deenergization in 12 hours to two groups of electrical equipment.Living needs that like this can more convenient people.
Structure of the present utility model is seen accompanying drawing, and accompanying drawing 1 is the clockwork spring deflated state, and accompanying drawing 2 is that the clockwork spring pine opens state.Go up a fixed installation microswitch (3) at the machine core board (1) of a common mechanical alarm clock (4), it must be attached to clockwork spring (2) limit of deflated state, as accompanying drawing 1; When the loose Zhang Shike of clockwork spring (2) promotes the contact of microswitch (3), make its switch state, as accompanying drawing 2, this is that the tension force that utilizes the clockwork spring pine to open process promotes microswitch, thereby realizes timing automatic control.
Mechanism's alarm clock that enforcement of the present utility model available one is common, can decide clock just in time in 12 hours, install microswitch by above-mentioned given organization plan, utilize three joints of microswitch (often to open for one group, one group normally closed), two groups of electrical equipment of break-make simultaneously just, and required timing only need be adjusted on alarm clock and gets final product.
The utility model has the advantages that and implement simply, realize electrical equipment reached 12 hours timing automatic open and close easily.
Claims (2)
1, multi-functional clock electrical equipment automatic switch, it is a standard machinery alarm clock, and clockwork spring (2) is arranged, and it is characterized in that: go up fixed installation one microswitch (3) at alarm clock movement plate (1).
2, microswitch according to claim 1 (3) is characterized in that: clockwork spring (2) limit that is attached to deflated state during installation.
