其中，第二关机电路106包括第三检测端106a以及控制信号输出端106d，其中，第三检测端106a电性连接于手动开关102，用于检测手动开关102是否接受输入操作，并且在检测到手动开关102接受到输入操作时获取电源信号。控制信号输出端106d电性连接开机控制电路104，第二关机控制电路106通过控制信号输出端106d将所述控制信号至开机控制电路104。
本实施方式中，开机信号为低电位，例如0V；开机信号为高电位，例如为3.5-5V。在本发明其他变更实施方式中，开机信号也可为高电位，关机信号为低电位，并不以此为限。
其中，需要说明的是，虽然本实施方式中，第一开机控制电路105与第二开机控制电路106同时存在，但第一开机控制电路105与第二开机控制电路106并不同时工作。当然，在本发明其他变更实施方式中，第一开机控制电路105与第二开机控制电路106也可以同时工作，也即是第二开机控制电路106辅助第一开机控制电路105进行工作，从而更加灵活的控制电源信号何时停止提供至电源信号输出端107以及负载电路（图1）的时间。
更具体地，请参阅图3，图3为图2所示开关机电路10的具体电路结构图。
电源开关103为一P型场效应管（Metel-Oxide-Semiconductor，MOS），其源极S电性连接所述第一连接端103a（图2），或者直接将所述源极作为第一连接端103a；漏极D电性连接所述第二连接端103b（图2），或者直接将所述漏极D作为第二连接端103b；栅极G电性连接所述控制端103c（图2），或者直接将所述栅极G作为控制端103c。较佳地，第一保护电阻R1并联于所述源极S与所述栅极G之间，以释放栅极G的电荷，防止所述P型MOS管的栅极G由于电荷累计而导致电压过高被损坏。
由于电源开关103为一P型MOS管构成，可知，当电源开关103接收到一低电位信号时，例如0V信号时，所述P型MOS管导通，从而使得源极S与漏极电性导通，进而使得第一连接端103a与第二连接端103b电性导通，电源信号则自电源输入端101传输至电源输出端107。
当电源开关103接收到一高电位信号时，例如3.5V信号时，所述P型MOS管截止，从而使得源极S与漏极电性断开，进而使得第一连接端103a与第二连接端103b电性断开，任何电源信号则可靠地无法自电源输入端101传输至电源输出端107，从而保证负载电路30的静电消耗为零。
开机控制电路104包括自第一检测端104a（图2）开始依次串联的第一导向二极管D1、第一限流电阻R2、第一充电电容C1以及接地端GND。其中，第一导向二极管D1的阳极（未标示）电性连接所述第一检测端104a，阴极（未标示）连接所述第一限流电阻R2。同时，第一限流电阻R2与第一充电电容C1之间的任意一节点作为第一控制端104b。第一充电电容C1能够在接受到电源信号时在第一时间内完成充电，达到指定电压进而输出对应的开机信号，例如9.8V。另外，本实施方式中，开机控制电路104还包括一限流电阻（未标示）并联于第一充电电容C1，用于保护第一充电电容C1。
进一步，开机控制电路104还包括第一稳压二极管DZ1以及第一控制开关Q1。其中，第一稳压二极管DZ1的阳极电性连接所述第一控制端104b，阴极则电性连接于第一控制开关Q1，用于提供一稳定的控制电压至第一控制开关Q1。
第一控制开关Q1为一N型晶体管，其基极b电性连接第一稳压二极管DZ1；集电极e电性连接接地端GND；发射极c通过一用作限流用的电阻（未标示）连接至信号输出端104c。第一控制开关Q1在第一稳压二极管DZ1稳定的反向导通电压，例如高电位控制下处于导通状态，从而将接地信号（0V）作为开机信号传输至信号输出端104c。另外，本实施方式中，开机控制电路104还包括一保护电阻（未标示）电性连接于第一控制开关的基极b与集电极e，用于保护基极b，防止集电极e累积电荷。
进一步，开机控制电路104还包括一自锁二极管D2，其阳极（未标示）电性连接电源输出端107，阴极（未标示）电性连接第一限流电阻R2。自锁二极管D2用于在手动开关102未接受到输入操作时将电源信号持续提供给第一充电电容C1，从而保证第一开机控制电路104持续提供开机信号至电源开关103，保证电源信号持续提供至负载电路30，达到自锁功能。
第一关机电路105包括自第二检测端105a开始依次串联的第二导向二极管D3、第二限流电阻R3、第二充电电容C2以及接地端GND。其中，第二导向二极管D3的阳极（未标示）电性连接第二检测端105a，阴极（未标示）电性连接所述第二限流电阻R3。第二导向二极管D3用于使得电源信号自第二检测端105a输入，第二限流电阻R3用于限制第二充电电容C2的充电电流与充电时间。第二充电电容C2用于检测手动开关102是否持续第二时间接受输入操作，并且当检测到手动开关102持续第二时间接受输入操作时，输出第二电压信号，所述第二电压信号为高电位信号，例如7V；当检测到手动开关102并未持续第二时间接受输入操作时，并不输出第二电压信号。
本实施方式中，第二充电电容C2充电完成的时间等于第二时间。由此，当第二充电电容C2在第二时间内充电完成时，其充电电压达到7.0V；当第二充电电容C2未充电完成时，第二充电电容C2提供0V的电位信号进行输出。
进一步，第一关机控制电路105还包括依次串联的分压稳压二极管DZ2、第一分压电阻R4、第二保护电阻R5，且所述分压稳压二极管DZ2、第一分压电阻R4、第二保护电阻R5与第二充电电容C2并联。分压稳压二极管DZ2用于在第二充电电容C2输出第二电压信号时提供一稳定的反向稳定电压，并且经过第一分压电阻R4与第二保护电阻R5分压后输出稳定的启动电压，本实施方式中，启动电压为0.7V。
第一关机电路105还包括第二控制开关Q2，第二控制开关Q2用于依据启动电压输出所述的控制信号。
第二控制开关Q2位一N型晶体管，其基极b电性连接第一分压电阻R4与第二保护电阻R5之间任意一节点，用于接收所述启动电压；集电极e电性连接接地端GND；发射极c电性连接所述控制信号输出端105b或者直接作为控制信号输出端105b。第二保护电阻R5还并联于第二控制开关Q2的基极b与集电极e两端，用于保护第二控制开关Q2。
当第二开关Q2接收到启动电压时处于导通状态，从而使得第二控制开关Q2的发射极c与集电极e电性导通，也即是第二控制开关Q2的发射极c的电位等于接地端GND电位，进而输出低电位的控制信号至控制信号输出端105b。当第二控制开关Q2未接收到启动电压而处于截止状态时，并未输出控制信号至控制信号输出端105b。
优选地，第一关机控制电路105还包括一防止误触发电路1051，用于保证第二充电电容C2在未充电完成时并不输出所述启动电压。
防止误触发电路1051包括第三控制开关Q3与限压电阻R6，限压电阻R6一端连接于第二导向二极管D3的阴极，另一端连接接地端GND，限压电阻R6用于为第三控制开关Q3提供一参考用的基准电压，其中，所述基准电压等于第二充电电容C2充电完成所具有的电压与第三控制开关Q3导通电压之和，例如为7.3-7.7V。
第三控制开关Q3为P型晶体管，其集电极e电性连接第二充电电容C2相对于连接接地端GND的一端；基极b电性连接限压电阻R6相对连接接地端GND的一端；发射极c电性连接接地端GND。在第三控制开关Q3的集电极e小于其基极b的电压时，也即是小于限压电阻R6获得的基准电压时，第三控制开关Q3导通，由此，第二充电电容C2并无法输出启动电压；在第二充电电容C2未充电完成并且达到7V时，也即是大于或者等于所述基准电压时，第三控制开关Q3处于截止状态，第二充电电容C2则利用其充电获得的电压提供第二电压信号，进而输出启动电压至第二控制开关Q2，有效达成防止手动开关102的误触发，也即是未达到第二时间的输入操作。
第二关机电路106包括转换电路1061、转换信号输出端106b、微处理电路1062、启动信号输出端106c以及第四控制开关1063。
本实施方式中，第三检测端106a电性连接第二导向二极管D3的阴极，以通过第二导向二极管D3在手动开关102接收到输入操作时获取电源信号。可变更地，第三检测端106a可直接电性连接至手动开关102的第二传输端102b（图2），或者通过另外的导向二极管D3电性连接至手动开关102的第二传输端102b，并不以此为限。
转换电路1061电性连接第三检测端106a与转换信号输出端106b之间，用于将电源信号依据输入操作的操作时间转换为所述的脉冲信号，并且自转换信号输出端106b输出。其中，转换电路1061包括自第三检测端106a依次串联的转换电阻R7与转换稳压二极管DZ3，其中，转换稳压二极管DZ3的阳极电性连接接地端GND，阴极电性连接转换电阻R7。
具体地，请参阅图4，其为经转换电路1061转换后的脉冲信号的时序图。在手动开关102接收到第一时间的输入操作时，第一转换电路1061转换获得具有第一脉宽P1的第一脉冲信号S1，其中，脉冲信号的电位为3.5V；当手动开关102未接收到输入操作时，脉冲信号的电位为0V；当手动开关102接收到第二时间的输入操作时，第一转换电路1061转换获得具有第二脉宽P2的第二脉冲信号S2，其中，脉冲信号的电位为3.5V，对应第二时间的第二脉冲信号S2的宽度为对应第一时间的脉冲信号S1的三倍。可见，第一、第二脉冲信号S1、S2可分别表示输入操作的操作时间，进而能够清楚表明输入操作的类型，例如第一脉冲信号S1表示操作时间为第一时间，也即是开机操作，第二脉冲信号S2表示操作时间为第二时间，也即是关机操作。本实施方式中，所述脉冲信号为TTL电平脉冲信号。
微处理电路1062用于依据脉冲信号S1、S2对应识别手动开关102接收的输入操作的操作时间，进而识别手动开关102是否接收到关机操作。并且当识别出脉冲信号S2时，输出启动信号至启动信号输出端106c。其中，启动信号为高电位，例如3.5V。
第四控制开关1063为一N型晶体管Q4，其基极b通过一分压电阻（未标示）电性连接启动信号输出端106c；集电极e电性连接接地端GND；发射极c电性连接所述控制信号输出端106d或者直接作为控制信号输出端106d。较佳地，晶体管Q4的基极b与集电极e还包括一保护电阻（未标示），用于保护晶体管Q4的基极b防止聚集电荷。
当晶体管Q4接收到启动信号时处于导通状态，从而使得晶体管Q4的发射极c与集电极e电性导通，也即是晶体管Q4的发射极c的电位等于接地端GND电位，进而输出低电位的控制信号至控制信号输出端106d。当晶体管Q4未接收到启动信号而处于截止状态时，并未输出控制信号至控制信号输出端106d。
下面结合图3，具体说明开关机电路10的工作过程。
上电开机过程：
当手动开关102接受到持续第一时间的输入操作时，其第一传输端102a与第二传输端102b电性导通，电源信号通过第一导向二极管D1、第一限流电阻R2对第一充电电容C1充电，第一充电电容C1则在第一时间内完成充电达到指定电压9.8V。第一充电电容C1的指定电压通过第一稳压二极管DZ1反向导通分压后提供一开启电压至第一控制开关Q1，从而使得第一控制开关Q1导通，从而输出一低电位的开机信号至电源开关103。
电源开关103在低电位的开机信号驱动下电性导通，使得第一连接端103a与第二连接端103b电性导通，电源信号则自电源输入端101传输至电源输出端107以及负载电路30，从而为负载电路30供电。
于此同时，自锁二极管D2自电源输出端107将电源信号持续提供至第一充电电容C1，保证第一充电电容C1持续维持在指定电压，从而对应持续输出低电位的开机信号至电源开关103，使得电源开关103持续维持在导通状态，进而保证电源信号持续自电源输入端101传输至电源输出端107以及负载电路30。
由此，当手动开关102第一时间后停止接受到输入操作，使得第一连接端103a与第二连接端103b电性断开，但通过自锁二极管D2仍然能够维持电源信号持续传输至负载电路30为其供电，达到开机完成后自我锁定的目的。
关机过程：第一关机控制电路105。
当手动开关102接受到持续第二时间的输入操作时，其第一传输端102a与第二传输端102b电性导通，电源信号通过第二导向二极管D3、第二限流电阻R3对第二充电电容C2充电。
在第二充电电容C2充电未完成前，防止误触发电路1051保证第二控制开关Q2并未接受到启动电压，从而有效防止手动开关102的误触发。
第二充电电容C2在第二时间内完成充电达到指定电压7.0V后，第二充电电容C2的指定电压通过分压稳压二极管DZ2反向导通分压后提供一开启电压至第二控制开关Q2，从而使得第二控制开关Q2导通，从而输出一低电位的控制信号至第一控制端104b。
当第一控制端104b接收到所述低电位的控制信号时，第一充电电容C1快速放电至低电位，由此，第一控制开关Q1截止，从而自信号输出端104c输出一高电位的关机信号至电源开关103，电源开关103则在高电位的关系控制下截止，则第一连接端103a与第二连接端103b断开，电源信号停止传输至电源输出端107以及负载电路30。
关机过程：第二关机控制电路106。
请一并参阅图3与图4，当手动开关102接收到输入操作时，第一传输端102a与第二传输端102b电性导通，电源信号经由手动开关102传输至转换电路1061。转换电路1061则依据接收到电源信号的时间长度转换获得对应时间宽度的第一、第二脉冲信号S1、S2，例如对应第一时间的第一脉冲信号S1与第二时间的第二脉冲信号S2，其中，第一时间则对应开机操作，第二时间则对应关机操作。
转换电路1061将第一、第二脉冲信号S1、S2通过转换信号输出端106b传输至微处理电路1062，微处理电路1062识别获得第二脉冲信号S2时，则对应输出所述启动信号至启动信号输出端106c，第四控制开关1063在启动信号控制下处于导通状态，从而对应输出一低电位的控制信号至第一控制端104b。
当第一控制端104b接收到所述低电位的控制信号时，第一充电电容C1快速放电至低电位，由此，第一控制开关Q1截止，从而自信号输出端104c输出一高电位的关机信号至电源开关103，电源开关103则在高电位的关系控制下截止，则第一连接端103a与第二连接端103b断开，电源信号停止传输至电源输出端107以及负载电路30。
可见，第二关机控制电路106能够自动检测手动开关102的输入操作的操作时间，从而判断其操作类型，并且在接受到对应的操作后依据实际需要在预定时间内输出对应的控制信号，达到定时关机的功效。
相较于现有技术，所述开关机电路10通过开机控制电路104、第一关机控制电路105能够按照外部用户输入操作的操作时间实现电源信号的供给与否，达成开关机电路10的多功能操作，操作较为方便。
进一步，当所述开关机电路10控制电源信号停止提供至负载电路30时，保证电源信号可靠地停止传输，使得负载电路30的静电功耗较低，从而提高了雾滴检测仪1的工作稳定性以及寿命。
再次，所述开关机电路10中的第二关机控制电路106能够依据输入操作以及操作时间识别对应的操作类型，并且对应按照实际需求在预定时间输出对应的控制信号，进而达成关机信号输出时间可控，提高了操作的灵活性。
其中，第一关机控制电路105与第二关机控制电路106并不同时工作，也即是第一关机控制电路105与第二关机控制电路106可分别在不同时间提供控制信号至关机控制电路104，实现停止提供电源信号至负载电路30（图1）从而达成雾滴检测仪1（图1）的关机。
可以理解的是，本领域技术人员还可在本发明精神内做其它变化等用在本发明的设计，只要其不偏离本发明的技术效果均可。这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围之内。
