A timing device, which comprises at least two time setting display lights, with each of the time setting display lights representing an AC power supply time, and, after pressing a selection control button so as to light on at least two time setting display lights, by pressing the total time setting control button, the central control module can sum up the power supply times represented by all of the lighting time setting display lights to a total power supply time, and start the AC power supply to the load end as well as the power supply time countdown. Moreover, the central control module can further, based on the remaining power supply time, drive one or more time setting display lights to light on thereby indicating the remaining power supply time. |

1. A timing device, comprising:
an alternative current (AC) power source input module, used to input AC power; a direct current (DC) power source supply module, which is electrically connected to the AC power source input module and used to convert the AC power into the DC power; an AC power source output module, which is electrically connected to a load end in order to output the AC power to the load end; a relay, which is electrically connected to the AC power source input module, the DC power source supply module and the AC power source output module, wherein the relay is used to control whether the AC power inputted by the AC power source input module should pass through the relay to supply the power to the AC power source output module such that the AC power source output module can output the AC power to the load end; a central control module, which is electrically connected to the DC power source supply module in order to control the integral operation mechanism of the timing device; a relay driver circuit, which is electrically connected to the central control module and the relay, in which the central control module is able to connect to the relay by means of the relay driver circuit such that the power can be supplied to the AC power source output module; a time setting display light set, which includes at least two or more time setting display lights and is electrically connected to the central control module, wherein each time setting display light represents a power supply time, and the light-on or light-off in any one of the time setting display lights represents the status change in the control of the central control module; a selection control button, which is electrically connected to the central control module and is used to be pressed to select the power supply time, wherein pressing the selection control button can result in the light-on or light-off of such time setting display lights; a total time setting control button, which is electrically connected to the central control module and is used to be pressed to confirm the power supply time option, wherein, upon pressing the selection control button thus leading to light-on in one of the time setting display lights, it is possible to press once again the total time setting control button to confirm the input of the time represented by the time setting display light; and in case of pressing the selection control button thereby enabling the light-on in one of the time setting display lights without subsequently pressing once again the selection control button or the total time setting control button, the central control module is able to sum up the power supply times represented by all of the lighting time setting display lights to obtain a total power supply time, and start the power supply to the load end as well as the time countdown, and, also, the central control module can further, based on the remaining power supply time acquired by deducting the elapsed power supply time from the total power supply time, drive the light-on in one or more time setting display lights thereby indicating the remaining power supply time. |
