Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Refer to Fig. 1-7, a kind of inexpensive timer module, including outside port, power module, timing setting, state Instruction, power drive and timing controlled, the outside port input connection live wire input ACL and zero line input ACN, described outer Portion port output end connects power module and power drive respectively, and the power module is connected with timing controlled, the timing control System is connected with timing setting, power drive, state instruction.

Preferably, outside port maximal input is 230V 10A, the power drive is maximum to support power output For 230V 10A；Preferably, power module uses the circuit structure of Switching Power Supply, and the direct current for providing other circuit modules supplies Electricity；Preferably, power drive is realized using relay, pass through the logical of switching signal control relay caused by timing controlled Disconnected, the output of the relay is used for load supplying, meets load end 230V 10A requirement；Preferably, timing setting is used for Set timer timing, timing input button use two kinds of keystroke patterns of long-press and short-press, using 0.5 second as differentiation, Key press time was used as short-press less than 0.5 second, and key press time, which is longer than, is used as long-press for 0.5 second, and distinguishing the time can be according to the happiness of user Good and application habit is set, and beginning of the timing input using long-press as timing input, is then timed the time with short-press Setting, end of last long-press as timing input, the scheme set using a key, timer is set by a button Time, touch potential corresponds to timing, and timing is set from minimum to largest loop, and this timer module expires The requirement of sufficient button Key dithering, prevent from setting and malfunction；Preferably, state instruction is by setting 5 LEDs to indicate timer The power-up state of module and different timings；Preferably, timing controlled is realized using processor, timing can be read and set Fixed information, timing is then carried out, controlled in the different phase state of a control indicator lamp of timing, and by the information of timing setting The output of power drive, inside carry overheat protector function, improve the reliability of timer module, when timing starts, open work( Rate drives, and gives load upper electricity, at the end of timing, closes power drive, load power down.

Operation principle：The workflow diagram of the inexpensive timer module such as Fig. 2, after system electrification, on circuit starts Reset, the state of modules is detected, guarantee power drive is closed mode, and state instruction is in upper electric module（Indicator lamp Flashed by certain frequency）.Then excess temperature detection is carried out, whether detection temperature is too high, if too high, into overheat protector pattern （Indicator lamp is flashed by running lamp form, and upper electricity instruction and excess temperature instruction can be with self-defined）, until temperature is in safely controllable model Within enclosing.Subsequent timing controlled detection timing inputs, and regularly starts after detecting effectively input, is closed after timing terminates Close, status indicator lamp is ultimately at power-up state.
