Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0032] See Figs. 1-2 As shown in the figure, this application discloses a timer quick-set socket without an LCD, including a housing 1. The front of the housing 1 is recessed with a plug-in position 2 for inserting the end of the plug. The plug-in position 2 is provided with a neutral wire socket 21 and a live wire socket 22. A neutral wire conductive piece 31 is provided in the neutral wire socket 21, and a live wire conductive piece 32 is provided in the live wire socket 22. A neutral wire conductive post 41 and a live wire conductive post 42 are provided on the back of the housing 1. The neutral wire conductive piece 31 is electrically connected to the neutral wire conductive post 41. A circuit board for controlling the live wire conductive piece 32 and the live wire conductive post 42 to be turned on or off is provided inside the housing 1.
[0033] The housing 1 is provided with a function switching button 5 for controlling the normally closed, normally open or timed conduction of the live wire conductive sheet 32 and the live wire conductive post 42. On one side of the function switching button 5, the housing 1 is provided with a normally closed indicator light 51 for displaying that the live wire conductive sheet 32 and the live wire conductive post 42 are normally closed. On the other side of the function switching button 5, the housing 1 is provided with a timed conduction indicator light 52 for displaying that the live wire conductive sheet 32 and the live wire conductive post 42 are timed conduction.
[0034] The housing 1 is provided with at least one timer duration setting button 6 for controlling the timed conduction duration between the live wire conductive sheet 32 and the live wire conductive post 42. The housing 1 is provided with a timer duration setting indicator light 61 on one side of each timer duration setting button 6.
[0035] Function switch button 5, normally closed indicator light 51, timer on indicator light 52, timer duration setting button 6 and timer duration setting indicator light 61 are all electrically connected to the circuit board.
[0036] In this embodiment, the conduction of the entire socket is achieved by the function switching button 5 to realize normally closed, normally open or timed conduction, so that the socket has different output states and is easy to set; the timed duration setting button 6 can be used to directly set a specific duration without other operations, so the operation is simple.
[0037] The function switch button 5 is labeled "ON / OFF / AUTO". There are two timer duration setting buttons 6, one labeled "P1" and the other labeled "P2".
[0038] Specifically: Press function switch button 5.
[0039] If neither the normally closed indicator light 51 nor the timed on indicator light 52 is lit, it indicates that the socket is in normally open mode, which means it is always in the off state and the current cannot flow from the live wire conductive piece 3 to the live wire conductive post 42.
[0040] If the normally closed indicator light 51 is lit, it indicates that the socket is in normally closed mode, which means it is always in a conductive state, and the current can always flow from the live wire conductive piece 3 to the live wire conductive post 42.
[0041] If the timed conduction indicator light 52 is lit, it indicates that the socket is in timed conduction setting mode. Press the timed duration setting button 6 to set the timed conduction time with one click (for example, after pressing the timed duration setting button 6 on P1, the timed duration setting indicator light 61 next to P1 will flash first and then stay on, with a default timed conduction time of 3 hours; press the timed duration setting button 6 on P2, the timed duration setting indicator light 61 next to P2 will flash first and then stay on, with a default timed conduction time of 9 hours), so that the socket can conduct at the designated time every day.
[0042] In this embodiment, the housing 1 is provided with a timer plus button 7 for increasing the timed conduction duration of the live wire conductive sheet 32 and the live wire conductive post 42, and a timer minus button 8 for decreasing the timed conduction duration of the live wire conductive sheet 32 and the live wire conductive post 42. The housing 1 is provided with a timer plus indicator light 71 on the side of the timer plus button 7 for indicating that the timer plus button 7 has been successfully triggered, and the housing 1 is provided with a timer minus indicator light 81 on the side of the timer minus button 8 for indicating that the timer minus button 8 has been successfully triggered. The timer plus button 7, the timer minus button 8, the timer plus indicator light 71 and the timer minus indicator light 81 are all electrically connected to the circuit board.
[0043] The timer increment button 7 is marked with "+30min", and the timer decrement button 8 is marked with "-30min". These markings facilitate the identification of the function of each button.
[0044] The timer durations of P1 and P2 can be adjusted using the timer increase button 7 and the timer decrease button 8. Specifically, pressing P1 initiates the adjustment of the first time period's duration. The timer duration setting indicator 61 will flash first, indicating the start of the timer adjustment state. Then, pressing the timer increase button 7 and the timer decrease button 8 adjusts the duration of the first time period. For example, pressing the timer increase button 7 will cause the timer increase indicator 71 to flash once, indicating a successful trigger and an increase of 30 minutes in the timer duration. This can be repeated by pressing the timer increase button 7 multiple times. If neither the timer increase button 7 nor the timer decrease button 8 is triggered within one minute, the timer duration setting indicator 61 will remain constantly lit, and the socket will conduct electricity according to the adjusted timer duration. Similarly, pressing the timer decrease button 8 has the same effect.
[0045] In addition, the timer up button 7 and timer down button 8 can also adjust the default timer duration of P1 and P2. Specifically, quickly press P1 twice to start adjusting the default timer duration for the first time period. At this time, the timer duration setting indicator 61 will flash. Press the timer up button 7 or the timer down button 8 to adjust the default timer duration. If neither the timer up button 7 nor the timer down button 8 is triggered within one minute, the timer duration setting indicator 61 will turn off. Subsequent presses of P1 will activate the timer according to the newly set default timer duration. For example, if the default timer after pressing P1 was originally 3 hours, and after adjustment the default timer to 5 hours, then when switching to the timer function using the function switch button 5, the default timer will be 5 hours. Of course, this can still be adjusted using the timer up button 7 and the timer down button 8.
[0046] In this embodiment, when the timer duration setting indicator 61 is lit, the timer program corresponding to P1 or P2 can be deleted by pressing and holding P1 or P2. For example, pressing and holding for 5 seconds deletes the program.

The first terminal of the relay J1 contact is electrically connected to the live wire conductive piece 32. The second terminal of the relay J1 contact is electrically connected to the live wire conductive post 42.
[0049] The transistor Q1 controls the energization or de-energization of the relay J1 coil, thereby causing the relay J1 contacts to close or open, thus achieving power output.
