The present invention relates generally to a timer. More particularly, the present invention relates to a photo-timer module.
Previous photo-control timer consisting mainly of input power outlet, output power outlet and is forming a single product. According with the molding vibration of the timer, respectively place button, photo-sense device, display window, LED indicator etc. on the photo-control timer. Such type photo-control timer has been used for a long time. Once a vibration of function, structure or molding has been made, the molding or housing of the photo-control timer must be redesigned. Therefore, results in waste and increases production cost.
As a result, an improved photo-control timer that reduces production time, defects, and lower production costs is needed.
It is an object of the present invention to provide a photo-timer module that reduces production time, defects, and lower production costs.
In accordance with one embodiment of the invention, an photo-timer module is provided comprising: an upper cover which has a hollow window; a lower cover which could affix to said upper cover; a control and power circuit which is placed into said upper cover, wherein a portion of said control and power circuit is revealed in said hollow window, said control and power circuit has a plurality of input pins and a plurality of output pins, wherein the plurality of input pins and the plurality of output pins are stretching out of said lower cover; a mask plate placing above said hollow window comprises at lease one hole thereon, so that a portion of said control and power circuit is revealed in said hollow window, and a transparent plate placing above said mask plate is used for protecting and convenient observing said control and power circuit; after assembly, said control and power circuit could control a power on or off by sensing variation of a light and show the status on said hollow window.
The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.
a) and (b) are explosive views of a photo-timer module in accordance with one embodiment of the present invention.

Wherein, the upper cover 1 has a hollow window 11 in shape of circle which could place a mask plate 12 over it and offers at least one hole 121 on the mask plate 12 so that a portion of the control and power circuit 3 is revealed in said hollow window 11 for convenient observing; a transparent plate 13 placing above the mask plate 12 is used for protecting the control and power circuit 3 and increasing the pleasing to the eye. The lower cover 2 could affix to the upper cover 1 and one side of the lower cover 2 is connecting with the upper cover 1. The lower cover 2 further comprises a plurality of holes 21 for fixing.
