电路板121和电源引线的外侧还覆盖有外壳，外壳可开设有第一开口127和第二开口，导电金属件125的一端穿过第一开口127与第一引线段123未与电池122连接的一端连接，导电金属件125通过固定件101固定于外壳上，例如，导电金属件125通过螺钉固定于外壳上。而导电部126则通过第二开口外露，在保证第一引线段123与第二引线段124可连接的同时，保护电路板121和电源引线。
导电金属件125为弹性金属件，其一端通过螺钉固定于外壳上，另一端自由，方便绝缘片129的放置和抽离。
在一些实施例中，导电金属件125朝向导电部126的一侧可形成有向导电部126凸出的凸起，如图1所示，导电金属件125背离导电部126的一侧向导电部126凹陷，在导电金属件125背离导电部126的一侧形成凹槽125a，在导电金属件125朝向导电部126的一侧形成前述的凸起。
绝缘片129被从导电金属件125与导电部126之间抽离时，凸起与导电部126接触，如此方便导电金属件125与导电部126的良好接触。
电路板121、电池122、电源引线的外表面均可涂敷三防漆，以保护电路板121、电池122及电源引线免受环境侵蚀。
图4是根据本发明一个实施例的电脑板120的示意性结构图，示出了芯片和低速晶振。
如图4所示，本实施例的电脑板120的至少一个作用可用于控制指示灯128的点亮和熄灭，以向用户展示相关部件的状态。具体地，电脑板120还包括连接于电路板121上的芯片102、高速晶振(未示出)、低速晶振103以及指示灯128，高速晶振、低速晶振103、指示灯128分别与芯片102连接，芯片102则配置为通过高速晶振和/或低速晶振103计时，以控制指示灯128的点亮和/或熄灭时间，从而向用户展示相关部件的不同状态。
具体地，芯片102可配置为在电路板121被初次上电时，通过高速晶振计时，控制指示灯128以点亮第一预设时间，熄灭第二预设时间的方式闪烁循环第一预设次数。例如，第一预设时间、第二预设时间均为0.5s，第一预设次数为5，高速晶振计时，控制指示灯128进行5个循环闪烁，闪烁过程为亮0.5s、熄灭0.5s，以此向用户传达相关部件开始工作的提示。
芯片102还配置为在指示灯128闪烁第一预设次数之后，通过低速晶振103计时。也即是说，前述示例的5个循环闪烁结束后，芯片102利用低速晶振103计时，计时周期为下述的第三预设时间，第三预设时间可以为相关部件的工作寿命，例如，第三预设时间为一年。
芯片102还配置为在低速晶振103计时第三预设时间后，通过高速晶振计时，控制指示灯128点亮第四预设时间，再通过低速晶振103计时，控制指示灯128熄灭第五预设时间的方式闪烁循环第二预设次数，以提示用户相关部件需要更换。第三预设时间大于第一预设时间，并大于第二预设时间，并大于第四预设时间，并大于第五预设时间。例如，第三预设时间为1s，第四预设时间为5s，指示灯128以电量1s熄灭5s的闪烁状态，提示用户相关 部件寿命到期，需要及时更换。
低速晶振103可设置于芯片102的外部，而高速晶振可集成于芯片102的内部。
本实施例利用高速晶振和低速晶振分情况及时，利用高速晶振计时较短，利用低速晶振103计时较长，可降低电脑板120的整体电量消耗，延长电池122的使用时间。
前述的相关部件可以为下述的除味部件130，除味部件130可通过物理吸附作用对冷藏冷冻装置100进行除味净化。本实施例的电脑板120的芯片102通过控制指示灯128的闪烁，向用户展示除味部件130的工作状态，便于及时更换吸附饱和的除味部件130。
图5是根据本发明一个实施例的冷藏冷冻装置100的示意图。
如图5所示，本实施例还提供了一种冷藏冷冻装置100，包括限定有储物间室111的箱体110以及前述任一实施例的电脑板120，其中，电脑板120放置于储物间室111内，绝缘片129的放置或抽离可以由用户操作，由用户决定电脑板120的开启时间。
电脑板120的作用可以是利用其上的指示灯128向用户展示相关部件的状态，相关部件可以为除味部件130。具体地，除味部件130设置于储物间室111内，用于吸附储物间室111内的异味，达到除味、净化的效果。例如，除味部件130包括可吸附储物间室111内异味的吸附模块，吸附模块具有一定的寿命，当吸附模块吸附饱和时，需要从储物间室111内取出进行解吸或更换新的吸附模块。
为向用户展示除味部件130的状态，如前所述，本实施例的电脑板120还包括连接于电路板121上的芯片102、高速晶振、低速晶振103和指示灯128，高速晶振、低速晶振103、指示灯128均与芯片102连接，芯片102配置为通过高速晶振和/或低速晶振103计时，以控制指示灯128的点亮和/或熄灭时间，从而向用户提示除味部件130的状态。
除味部件130和电脑板120可拆卸地连接，放置于储物间室111的同一位置。冷藏冷冻装置100可以为冰箱、冷柜等具有冷藏、冷冻存储功能的装置。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根 据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
