具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
如图1-5所示，为本发明的一较佳实施例的气泵100。气泵100一般应用于打气、充气等场景中，用以将气泵100产生的气体输送至待充气设备中。根据动力源的不同，气泵100可以分为以电力为动力的电动气泵、以手力为动力的手动气泵、及以脚力为动力的脚动气泵。其中，手动气泵通过手力不停的压缩空气，以产生气压，主要用于填充气球或可填充式气动小玩具；脚动气泵通过脚力不停的压缩空气，以产生气压，主要用于为自行车打气，填充气球或气动小玩具等。在本实施例中，动力源为电机，气泵100为电动气泵，其可以用于打气、污水处理、电镀鼓气、沼气池曝气、隧道通风等场景，本申请不对气泵100的应用场景做具体限定。
请参见图1和图2，气泵100以在载置于载置面(例如地面、底板、顶棚等)的状态下使用为前提而构成，因此，为了便于对气泵100的描述，以气泵100载置于作为平面的载置面时的姿势为基准而规定气泵100的上下方向，将与上下方向正交的方向规定为气泵100的前后方向，将气泵100出气的方向规定为前方，与前方相反的方向为后方，并且将与上下方向以及前后方向正交方向规定为左右方向。
本申请中的气泵100包括电机3、气体压缩组件2、用以收容电机3以及气体压缩组件2的主机壳体119、用以支撑主机壳体119的支撑脚9、以及与主机壳体119连接的握持部115。主机壳体119还设置有操作部5、用于安装直流电 源的安装部6以及灯光组件10。其中，灯光组件10位于操作部5的下方，该操作部5的正投影与灯光组件10的正投影至少部分重叠，在本实施例中，该灯光组件10的正投影全部落于操作部5的正投影内。
该主机壳体119包括基部1191、前侧延伸部1192以及后侧延伸部1193，具体的，基部1191是主体壳体119中的沿前后方向延伸的部分。前侧延伸部1192以及后侧延伸部1193分别与基部1191的前端部以及后端部连接、且沿上下方向延伸。前侧延伸部1192以及后侧延伸部1193比基部1191更向上方突出。握持部115的前端部以及后端部分别与前侧延伸部1192以及后侧延伸部1193的上端部连接。由此，主体壳体119以及握持部115形成为近似D字状的环状，如图1所示。
主机壳体119、支撑脚9和握持部115共同形成气泵100的外壳1。在本实施例中，外壳1由两个半half结构对接而成，两个半half分别为左右结构，通过此种设置，便于开模，使得整体结构更为简单。外壳1具有相对设置的前表面11和后表面12、相对设置的上表面14和下表面15以及相对设置的两侧面13。外壳1由前表面11、后表面12、上表面14、下表面15及两侧面13围设形成用以容置气缸21和电机3的容置腔(未标号)。具体的，气缸21设置在前侧延伸部1192内，电机3设置在基部1191内。主机壳体119与握持部115之间形成有握持腔112，该握持腔112通过贯穿两侧面13而形成，操作者的手从外壳1的侧面13穿入至握持腔112内。握持部115位于主机壳体119的上方，具体的，握持部115位于握持腔112的上方，并与下表面15平行地延伸。
主机壳体119还具有用于将气体压缩组件2排出的压缩空气引导至待充气设备的插接口111。该插接口111和安装部6设置在握持部115的两侧，即插接口111和安装部6在握持部115的延伸方向上相对设置。一种可能的实施例中，气泵100还包括与气体压缩组件2连接并对接待充气设备的工作头7。工作头7的一端插入该插接口111以与气缸21连接。插接口111的中轴线X穿过握持腔112。本实施例中，握持部115与插接口111的中轴线X基本平行设 置，以便于操作及拿取。灯光组件10靠近插接口111设置，该灯管组件10位于操作部5和插接口111之间，具体的，灯光组件10位于插接口111的中轴线X的上方、位于操作部5的下方，握持部115位于灯光组件10的后方。
如图3所示，在本实施例中，前表面11上还内凹形成有安装槽113，安装槽113的开口方向与插接口111的开口方向相同，灯光组件10嵌入在安装槽113内，且由于工作头7的一端插入插接口111中，如此设置使得灯光组件10散发光的方向能面向工作头7所在的位置，有利于操作者在黑暗中操作工作头7。灯光组件10包括灯壳101和布置在灯壳101内的若干灯珠102。灯壳101与前表面11在竖直方向上齐平或大致齐平，以使得气泵100更加美观，结构紧凑，充分利用操作部5下方的空间，并且将灯光组件10设置在操作部5下方，灯光组件10散发的光由于操作部5的部分阻挡，使得光更聚集向前朝向工作头7，而不会过于向上散发，刺激在黑暗中操作者的眼睛。灯壳101可以保护灯珠102，延长灯光组件10的使用寿命。本实施例中，灯珠102包括可发出白光的第一类灯珠(未图示)和可发出红光的第二类灯珠(未图示)，灯珠可以选择性的被部分开启。
请参见图2，主机壳体119的前侧延伸部1192上设置有用以控制灯光组件10启闭的控制开关51。控制开关51设置在其中一个侧面13上，具体的，控制开关51位于握持部115与灯光组件10之间，且控制开关51位于操作者握持握持部115时的单手操作范围内，以使得操作者在使用控制开关51控制灯光组件10时能够单手操作，更加方便省力，提高舒适度。
控制开关51与灯光组件10信号连接，使得灯光组件10具有不同的显示状态，其中，不同的显示状态包括：显示白弱光、显示白强光、显示实现警示作用的红光以及灯光组件10关闭。不同状态通过第一类灯珠、第二类灯珠的启闭实现。此处，定义灯光组件10显示白弱光为第一工作模式、显示白强光为第二工作模式、显示红光为第三工作模式、以及灯光组件关闭第四工作模式。当气泵100在夜间等光线条件差的环境下工作时，根据光线的强度的不同，操作者可调节至第一工作模式或第二工作模式以选择灯光组件的照明强 度，当遇到紧急情况时，操作者可将灯光组件调节至第三工作模式以使得灯光组件显示红光，从而进行警示或呼救预警。
在本实施例中，控制开关51包括按压式的触发按钮511和接收触发按钮511的触发信号的第一控制器(未图示)，第一控制器位于安装槽113内。本实施例中，触发按钮511与不同状态之间的控制方式如下：当按压一次触发按钮511时，第一控制器控制灯光组件10显示白弱光；当按压两次触发按钮511时，第一控制器控制灯光组件10显示白强光；当按压三次触发按钮511时，第一控制器控制灯光组件10显示红光；当按压四次触发按钮511时，第一控制器控制灯光组件10的灯珠全部熄灭，即灯光组件关闭。
请参见图4，操作部5包括用以显示工作头7的出气数据的显示屏52、用以控制电机3的上电开关53和启闭开关、以及控制显示屏显示和电机转速的第二控制器(未图示)。需要说明的是，本实施例中，灯光组件10由控制开关51单独控制，具体为：灯光组件10、控制开关51构成第一回路。控制开关51控制该第一回路的通断。电机3、显示屏52、第二控制器、上电开关53和启闭开关54构成第二回路。第二回路和第一回路为非串联电路，上电开关53控制第二回路的通断，启闭开关54用以控制电机3的运行。
上电开关53、启闭开关54集成在显示屏52上，使得气泵100结构紧凑，节省空间。显示屏52还集成了用以设置气缸21输出目标气压值的操作按键(图4中的“+”、“-”)。外壳1具有上表面14，显示屏52嵌入在上表面14并位于灯光组件10的上方，这样设置的目的在于：一方面，当在夜晚或黑暗的环境下使用气泵100时，显示屏52可以在灯光组件10的作用下被操作者清晰的看到，进而对气缸21的输出值或目标值进行调节设置，以防止操作者在黑暗情况下不清楚气压值而产生的爆炸等伤害，在其他实施例中，还可以在显示屏52内设置照明件，使得操作者在黑暗情况下可以清晰的读出显示屏52的数据；另一方面，将显示屏52嵌入在上表面14，以使得显示屏52占用气泵100整体的空间更小，结构更紧凑。在其他实施例中，显示屏52还可以设置为其他位置，在此不作具体限定，根据实际情况而定。
如图2所示，气体压缩组件2包括气缸21和活塞；活塞在电机3的驱动下在气缸21内做往复运动以产生压缩气体，并通过工作头7将压缩的空气排出。气泵100还包括有设置在电机3与气缸21之间的传动组件，具体为：传动组件连接活塞杆与电机3的输出轴31，传动组件将电机3的输出轴31的旋转运动转变为直线运动以传递给活塞杆。传动组件包括传动件81和曲柄滑块机构(未图示)，在本实施例中，传动件81为齿轮组，齿轮组包括主动轮811和从动轮812。齿轮组的主动轮811安装在电机3的输出轴31上。在其他实施例中，传动件81还可以设置为其他，例如齿条传动、链条传动、连杆传动、凸轮传动、皮带传动等，在此不作具体限定，根据实际情况而定。曲柄滑块机构中的曲柄与齿轮组中的从动轮812连接，通过从动轮812驱动该曲柄做圆周转动，活塞杆安装在曲柄滑块机构中的滑块上，通过滑块推动活塞杆做往复的直线运动。当齿轮组带动活塞杆朝向靠近工作头7的方向移动时，压缩聚集在气缸21的气体体积变小，气缸21与工作头7连通，气缸21产生的气体沿着连通件71输送至待充气设备。
为了使得气泵100整机的稳定性更好，在工作时能够平稳的摆放在地面上，电机3和气缸2位于插接口111的中轴线X的下方。而为了使得该气泵的整体结构更为紧凑，本实施例中，气缸21的活塞杆垂直于插接口的中轴线X，外壳1内形成有气缸安装区114，气缸安装区114位于前表面11与握持腔112之间并靠下布置。电机3的输出轴31与插接口的中轴线X平行，沿握持部115的延伸方向，电机3位于安装部6与气体压缩组件2之间，具体的，电机3靠近气缸21布置，且电机3、气体压缩组件2、及安装部6比握持部115更靠近下方配置，气泵100的重心落在电机3内，于气泵100的高度方向上，电机3的正投影大部分落于握持部115的正投影内，如此设置，当气泵100工作或提携时，气泵100整体的重心均衡分布，进而使得操作者操作或提携时更加省力、舒适。
如图2和图4所示，气泵100由直流电源供电，在本实施例中，该直流电源为安装在安装部6上的电池包61，以使得气泵100在使用过程中不受距离的 限制。第一回路、第二回路均由电池包61供电。电池包61与安装部为可拆卸连接以方便对电池包61更换。为了使得操作者在使用气泵100安装电池包61时更方便，电池包61安装在气泵100上的插拔方向垂直于插接口的中轴线X。在其他实施例中，电池包61安装在气泵100上的插拔方向还可以设置为其他方向，在此不作具体限定，根据实际情况而定。
如图1和图2所示，工作头7包括供气泵100充气用的连通件71及对应的配件接头72，连通件71的一端插入至插接口111以与气缸21密封连接，连通件71的另一端与配件接头72连接，以向待充气设备充气，并且连通件71从插接口111的突出方向与握持部115的延伸方向大致平行。为了使得工作头7更加牢固的固定在插接口111上，工作头7还包括橡胶圈73，橡胶圈73可拆卸地安装在插接口111上，在其他实施例中，橡胶圈73还可以与插接口111一体成型。为了使得气泵100在充气时，连通件71可自由旋转以使得操作者方便操作，在本实施例中，连通件71设置为软管71，在其他实施例中，连通件71还可以设置为其他材质的通气管道，在此不作具体限定，根据实际情况而定。请参见图2和图5，外壳1的前表面11设置有收容槽116，该收容槽116位于插接口111的中轴线X的下方。当该气泵100未使用时，工作头7的配件接头72可被收容在收容槽116中，配件接头72可以为给篮球、排球、足球充气的球针，或给气球、气垫船充气的锥形转接头、法式气门嘴转接头等其他常用附件，以使得操作者更加方便。需要说明的是，为了使得气泵100整体结构紧凑，占用空间小，该收容槽116自前表面11向内凹陷形成。
请参见图4和图5，外壳1的两侧面13的其中之一的侧面13上设置有至少一个线夹91，为了更好的将未使用的软管71卡持固定缠绕在线夹91上，在本实施例中，线夹91设置为两个，两个线夹91分别设置在侧面13的两端且存在一定距离，且线夹91与外壳1一体成型设置，在本实施例中，线夹91与软管71之间为过盈配合，在其他实施例中，线夹91还可设置为可微调其收容范围，以防止软管71的直径过大时，线夹91出现卡持不稳定等问题，在其他 实施例中，不对线夹91的数量做具体限定，且线夹91还可以与外壳1分体设置，在此不作具体限定，根据实际情况而定。
如图1所示，外壳1上开设有连通电池包61与气缸安装区114的进风口117和出风口118，进风口117、出风口118形成用以冷却电机3、电池包61的气流通道，该气流通道内的气流流动方向为由进风口117进入，由出风口118流出，从而可以有效利用气流通道的结构，以使得从进风口117进入的气流可以直接流经电机3表面而加快散热。进风口117、出风口118设置在气泵100的侧面13上，以防止外壳1内的气流吹向操作者，从而提高操作者的使用舒适度。
当气泵100被放在路面上处于工作状态时，由于电机3运行会产生振动或抖动，进而导致气泵100在路面上摆放不平稳，容易倾覆，为了使得气泵100能够平稳的摆放在地面，气泵100还包括自下表面15向下突伸形成的支撑脚9，该支撑脚9具有减震作用，且该支撑脚9形成为矩形箱装。如图2所示，为了使得气泵100整体布局更紧凑，主动轮811设置在从动轮812的上方，从动轮812部分布置在支撑脚9内。在本实施例中，支撑脚9设置为两个，两个支撑脚9分别从前侧延伸部以及后侧延伸部的下端部向下方突出。在其他实施例中，支撑脚9的数量还可以设置为其他，在此不作具体限定，根据实际情况而定。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
