在上述实施例的基础上，本发明的第二实施例也提供一种汽车倒车镜面及 前门窗玻璃除水装置，如图 2所示， 该汽车倒车镜面及前门窗玻璃除水装置的 基本结构与上述实施例中的汽车倒车镜面及前门窗玻璃除水装置的基本结构 类似， 不同之处在于， 所述装置还包括智能开关 21 , 当储气罐 1 的容积只能 够同时满足左侧倒车镜面喷气孔及左侧前门窗玻璃喷气孔或者同时满足右侧 倒车镜面喷气孔及右侧前门窗玻璃喷气孔两个喷气孔的喷射用气量并能保证 去水珠效果时，需在左右两条管路上分别设置第一电磁阔 22和第二电磁阔 23 , 通过智能开关 21的预设程序对第一电磁阔 22和第二电磁阔 23进行交替循环 开启控制。
上述装置的工作过程为：压缩空气由空气压缩机 2的出气管进入储气罐 1， 储气罐 1中的空气压力达到设置在储气罐 1出气管上的第一压力继电器 4高压 设定值时， 第一压力继电器 4闭合， 接通智能开关 21 , 智能开关 21首先接通 储气罐 1出气管上的左侧气体管路上的第一电磁阔 22的电路， 使左侧气体管 路上的第一电磁阔 22开启， 储气罐 1中的压缩空气经储气罐 1的出气管、 左 侧气体管路上的第一电磁阔 22、 左侧气体管路上的第一电磁阔 22的出气管、 最后由设置在汽车左侧倒车镜上的左侧倒车镜面喷气孔及左侧前门窗玻璃喷 气孔喷射出一定压力的压缩空气，通过压缩空气的喷射去除左侧倒车镜面及左 侧前门窗玻璃上的水珠；储气罐 1中的压力降低至第一压力继电器 4的低压设 定值时， 第一压力继电器 4断开， 通向智能开关 21的电路断开， 左侧气体管 路上的第一电磁阔 22关闭， 压缩空气停止喷射。
当储气罐 1中的空气压力再次达到第一压力继电器 4高压设定值时，第一 压力继电器 4再次闭合， 接通智能开关 21 , 智能开关 21接通储气罐 1出气管 上的右侧气体管路上的第二电磁阔 23的电路， 使右侧气体管路上的第二电磁 阔 23开启， 储气罐 1中的压缩空气经储气罐 1的出气管、 右侧气体管路上的 第二电磁阔 23、 右侧气体管路上的第二电磁阔 23的出气管、 最后由设置在汽 车右侧倒车镜上的右侧倒车镜面喷气孔及右侧前门窗玻璃喷气孔喷射出一定 压力的压缩空气，通过压缩空气的喷射去除右侧倒车镜面及右侧前门窗玻璃上 的水珠； 储气罐 1中的压力降低至第一压力继电器 4的低压设定值时， 第一压 力继电器 4断开， 通向智能开关 21的电路断开， 右侧气体管路上的第二电磁 阔 23关闭， 压缩空气停止喷射。 如此通过智能开关 21预先程序设定， 左右两 侧交替循环喷射。
除此之外， 在上述实施例的基础上， 本发明的第三实施例也提供一种汽车 倒车镜面及前门窗玻璃除水装置，如图 3所示， 该汽车倒车镜面及前门窗玻璃 除水装置的基本结构与上述实施例中的汽车倒车镜面及前门窗玻璃除水装置 的基本结构类似， 不同之处在于， 当储气罐 1的容积只能够满足左侧倒车镜面 喷气孔或左侧前门窗玻璃喷气孔或右侧倒车镜面喷气孔或右侧前门窗玻璃喷 气孔一个喷气孔的喷射用气量并能保证去水珠效果时，每个喷射气体管路各设 置一个电磁阔， 第一压力继电器 4每次启闭智能开关 21电路时， 智能开关 21 安预置的程序依次循环启闭该四个电磁阔 （31、 32、 33、 34 ), 本实施例的具 体实施的工作过程和第二实施例基本相同， 在此不再赘述。
当然本装置中喷气孔的大小、 形状、 位置、 角度可以有多种选择方案， 以 获得满意的去除水珠效果为原则。 还有， 在汽车发动机处于怠速运行状态时， 为了保证空气压缩机能够正常工作并且汽车发动机不至于熄火，特别是使用充 气功能的时候， 汽车发动机通常要在怠速状态下运行。解决上述问题的办法就 是将去水珠功能开关及充气功能开关与空调压缩机使用的怠速提升装置连接， 以此来保证怠速状态下空气压缩机正常工作。而对于电动汽车或者具有较大电 容量蓄电池的汽车可以采用以蓄电池为动力电源的独立的空气压缩机。
对所公开的实施例的上述说明，使本领域专业技术使用者能够实现或使用 本发明。对这些实施例的多种修改对本领域的专业技术使用者来说将是显而易 见的， 本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下， 在其它实施例中实现。 因此， 本发明将不会被限制于本文所示的这些实施例， 而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
