如图1-2所示，本发明一实施例的电动喷洒装置包括储液器4、连接于储液器4上的壳体、以及设置于壳体内的液泵5、喷头组件22与电控组件7。
储液器4用于盛装需要喷洒的液体，如水或者添加有液态肥、杀虫剂、清新剂等的水溶液，其可以是水瓶、水壶或类似结构的容器。储液器4的顶端开口，一瓶盖406盖设于开口上将储液器4封闭。瓶盖406与储液器4较佳地螺合连接，即可以形成良好的密封，又可以方便地打开瓶盖406向储液器4内补充液体。图示实施例中，瓶盖406的外周面形成有外螺纹，用于与壳体螺合连接。应当理解地，瓶盖406与壳体也可以有其它连接方式，如可以是固定不可拆卸连接如焊接、粘粘等，或者也可以是可拆卸连接如卡扣、紧配合等，不以具体实施例为限。
本实施例中，储液器4内设置有软管401，用于储液器4向液泵5输送液体。软管401的顶端向上穿出储液器4，如由瓶盖406穿出等，与液泵5的进液管8连接。软管401的底端延伸至储液器4的底部，以尽可能地吸走储液器4内的全部液体。较佳地，软管401的顶端通过一固定架402与储液器4定位、软管401的底端套设有软管坠403。软管坠403起到配重的作用，避免软管401浮在液体表面而影响出液。固定架402固定于储液器4内并靠近其开口端设置，软管401穿设于固定架402的中央。较佳地，固定架402环绕软管401形成有若干镂空孔405，相邻的镂空孔405之间形成连接肋条404，在对软管401提供支撑的同时尽量避免影响对储液器4的液体补给。
壳体包括与瓶盖406连接的底座3以及罩设于底座3上的外壳1。底座3大致呈圆筒状，内部设置有隔板312，隔板312大致位于底座3的轴向的中间位置，将底座3的内部空间隔离为上下两部分。其中，底座3位于隔板312上方的部分与外壳1共同构成容置空间301，用于安装液泵5、喷头组件22与电控组件7；底座3位于隔板312下方的部分与储液器4上的瓶盖406套接，图示实施例中，底座3位于隔板下方的部分的内壁面形成有与瓶盖406的外螺纹相匹配的内螺纹。当然，底座3也可以形成其它与瓶盖406相匹配的连接结构。
请同时参阅图5，隔板312的中央设置有贯穿的进液孔310，进液孔310正对储液器4的软管401，设置于隔板312上方的液泵5的进液管8通过进液孔310与储液器4的软管401连接。图示实施例中，进液管8设置于液泵5的一侧、靠近底座3的边缘位置。一进液弯头311设置于隔板312上，其一端与液泵5的进液管8连接、另一管通过进液孔310与储液器4的软管401连接。进液弯头311的设置使得进液管8与软管401的相对位置不受限制，因此液泵5的进液管路的布置可以完全避开壳体内的其它元件，特别是电控组件7，一来可以更合理地利用壳体的内部空间使得整体结构更为紧凑，另一方面也减小了漏液等安全隐患，保障电控组件7的安全运行。
壳体内设置有支架6，用于安装液泵5以及电控组件7。电控组件7包括电池701、与电池701连接的控制电路板702、以及与控制电路板702连接的开关按键703。电池701作为整个电控组件7的电源，优选地为充电电池701。开关按键703设置于外壳1上，与控制电路板702上的触发开关706连接，用户通过按压开关按键703控制液泵5的启停。支架6整体呈柱状，沿周向设置有第一安装槽601、第二安装槽602以及第三安装槽603，分别安装液泵5、电池701以及控制电路板702。较佳地，液泵5为微型液泵，第一安装槽601内设置有弹性垫，用于减缓液泵5的震动，减小运行时的噪音。
通过支架6的设置，可以方便地装配电池701、控制电路板702以及液泵5，在安装定位后，可以方便地焊接导线将液泵5以及电控组件7的各个元件电性连接，充分合理地利用空间，方便元件的定位与连接。同时液泵5的进液管8偏置，避开了壳体中央的液泵5与电控组件7，这使得壳体内的诸多元件，特别是液泵5的进液管8与电控组件7的空间分布合理而紧凑，使得壳体可以有更小的尺寸，图示实施例中，壳体整体上的外径与储液器4上的瓶盖406的外径相当，远小于储液器4本身的外径，如此方便用户的使用与携带。
图示实施例中，底座3向上伸出有一对固定臂302，固定臂302的顶部形成有倒钩，对应地外壳1的内壁面上形成有卡扣位，装配时通过固定臂302的倒钩与外壳1的卡扣位的钩扣，将外壳1与底座3相连。应当理解地，底座3与外壳1也可以有其它可拆卸的连接方式如螺合等，或者也可以是不可拆卸连接，不以具体实施例为限。支架6与固定臂302形成有对应的固定孔604，螺钉303等固定件穿设于固定孔604内将支架6连接至固定臂302上。应当理解地，支架6与固定臂302也可以有其它连接方式。较佳地，支架6的底部与底座3的隔板312间隔出一定空间，以方便其它元件，如充电组件、泄压组件等的装配。
充电组件用于对电池701充电，包括充电电路板704与以及与充电电路板704连接的充电接口705。充电电路板704与控制电路板702连接，充电接口705可以是USB接口、Micro-USB接口、Type-C接口、Lighting接口等。对应地，底座3的隔板312上设置有充电槽306用于安装以及定位充电电路板704，底座3的侧壁上设置有正对充电接口705的缺口304，缺口304上连接有可开合的封帽305。封帽305常态下保持在闭合状态，避免外部的灰尘、杂物等堵塞充电接口705；封帽305打开时露出充电接口705，此时可以连接带有对应接头的充电器对电池701充电。
泄压组件包括形成于隔板312上的泄压槽307、密封泄压槽307的气密垫308、以及与泄压槽307连通的鸭嘴阀309。其中，气密垫308与泄压槽307共同形成泄压通道，泄压通道与充电槽306隔开，避免泄压过程中的水或水溶液溢出，导致电路短路。泄压通道的一端与鸭嘴阀309连通、另一端与封帽305连通。对应地，封帽305形成有气孔，连通泄压槽307与外界。
喷头组件2设置于外壳1的顶端，包括喷头盖201、喷头座202、喷盘件203以及喷嘴204。
喷头盖201罩盖于喷头座202上，喷头座202的外周面与喷头盖201的周向内壁面固定固定，如焊接形成良好的密封效果等。应当理解地，喷头盖201与喷头座202也可以有其它连接方式，不以具体实施例为限。喷盘件203设置于喷头盖201与喷头座202之间，喷盘件203上设置有多个过水孔，对应地喷头盖201设置有对应过水孔的多个出水孔。较佳地，喷盘件203与喷头座202之间还设置有环形的垫圈205，利用垫圈205在喷盘件203与喷头座202之间间隔出间隙，喷嘴204的出液在间隙处可以短暂停留，使得喷头组件2的出液更流畅。
喷嘴204固定于外壳1内并与液泵5的出液管连通，喷嘴204与外壳1可以是卡扣连接等。较佳地，外壳1与喷嘴204之间设置有防水密封圈101，避免水汽等进入外壳1而影响电控组件7的安全。本实施例中，喷嘴204与液泵5的出液管通过出液弯头206连接，从而使得喷嘴204与液泵5的相对位置可以根据需要进行设置，可以将喷嘴204调整至更适合的出液角度，应用上更为广泛、使用上更为方便。图示实施例中，喷嘴204的出液方向倾斜向上，从而最终喷头组件22的出液呈抛物线状，可以有更大的喷洒距离或喷洒范围。较佳地，喷嘴204出液的一端伸入至喷盘件203与喷头座202之间的间隙内。
喷头盖201与喷头座202固定连接，进而将喷盘件203、垫圈205集成为一体，在装配时只需将喷头盖201与外壳1相固定即可。喷头盖201与外壳1可以设置相匹配的螺纹结构螺合相连，也可以设置相配合的卡扣机构卡扣相连，无论安装还是拆卸都相当方便。另外，喷头盖201与喷头座202的一体结构在方便其本身的拆装的同时，也方便了喷头的更换，从而可以根据不同的应用场合使用不同的喷头，使得本发明电动喷洒装置的适用范围更广。
需要说明的是，本发明并不局限于上述实施方式，根据本发明的创造精神，本领域技术人员还可以做出其他变化，这些依据本发明的创造精神所做的变化，都应包含在本发明所要求保护的范围之内。
