Description
Technical field
The present invention relates to switching technique field, and in particular to a kind of switch auxiliary device of convenient dismounting.
Background technology
Discharge, setting can be arranged in toilet for convenience of by the foul smell in toilet in the toilet in town house at present
Gas is fanned, but most of exhaust fans are switched for hand, it is necessary to which people have gone up lavatory after a period of time, then enter exhaust fan
Close, and people are usually busy with other things after upper complete lavatory and forget to turn off exhaust fan, so as to cause energy waste；By
After complete lavatory on people's night, it will usually directly go to bed, whether open becomes one at this time or not exhaust fan nerve-wracking asks
Topic, if having opened can only wait until that turn off in the morning, causes waste of energy；If do not opened, when other people go to toilet, in toilet
Stink to high heaven, allow other people to suffer untold misery；
The switch that control socket can be set to be powered on also existing family's socket, to be convenient for people to when in use, it is not necessary to
Frequently plug plug, increases the service life of plug and plate；People are when cooking, cooking gruel and decocting medicinal herbs, it is necessary to boil specific
Time, so needing a kind of control device to control the service time of electric appliance；Although it is vented now with intelligent electric appliance and intelligence
Fan controls the service time of electric appliance and exhaust fan to set the time, but this equipment is not only expensive, but also each electricity
Control system on device can only control respective electric appliance respectively, and existing switch auxiliary device is needing what is controlled by adsorbing
On the wall for switching side, the switch that needs to control by the extension and contraction control of motor, but there is switch auxiliary device absorption and exist
After on wall, the distance between switch controlled with needs is excessive, causes switch auxiliary device to use, and since motor is defeated
Outlet and the switch contact for needing to control, are easily damaged, there is the problem of maintenance is inconvenient.
The content of the invention
Based on above technical problem, the present invention provides a kind of switch auxiliary device of convenient dismounting, so as to solve existing
There are lavatory exhaust fan and other electric appliances to realize that timing function is of high cost, and the control system on each electric appliance can only control respectively
The distance between respective electric appliance and after there is switch auxiliary device absorption on the wall, switch for needing to control are excessive, cause
Switch auxiliary device cannot use, and due to motor output end and the switch contact for needing to control, be easily damaged, there is maintenance
Inconvenient technical problem.
The technical solution adopted by the present invention is as follows：
A kind of switch auxiliary device of convenient dismounting, including time switch body, the time switch body trailing flank are set
