Description

一种喷枪 技术领域
本发明涉及一种电动工具，尤其涉及一种喷枪。
背景技术
电动喷枪是利用液体或压缩空气迅速释放作为动力的一种设备，通常用于喷洒，清洁。现有技术中根据不同需求也有各种不同结构的喷枪。现有技术中，为了加液方便，通常将加液壶设置为一个可拆卸的结构。但是当工作量较大的时候，加液壶拆卸下来也是相当麻烦的，为了提高加液效率，我们选择在加液壶的盖体上设置一个加液口。但是现有技术中考虑到加液效果以及密封效果，通常无法这样设置。
发明内容
本发明所要解决的技术问题是针对上述现有技术存在的技术问题，提供一种喷枪，在确保了喷液效果的前提下，提高加液壶加液的效率，枪体也能更有效的利用加液壶里的资源，减少浪费。
本发明解决上述技术问题所采用的技术方案为：一种喷枪，包括枪体，其特征在于：还包括有一加液壶，所述枪体通过连接柱固定有一个加液壶盖体，所述加液壶盖体和加液壶匹配盖在加液壶开口上，所述加液壶盖体上方开有加液口，所述连接柱的底部插配连接有一吸液管，所述吸液管通过连接柱使加液壶和枪体内部连通。
优选的，所述加液口上设有封闭装置。这样不仅是为了减少加液壶内液体挥发，而且确保使用喷枪时加液壶内的压力。
优选的，所述加液壶盖体的顶部向上延伸出有一圈延伸壁而形成所述加液口，所述封闭装置为密封盖，且与该延伸壁相适配而能活动启闭地盖合在该加液口处。这样的结构加工简单，密封效果好。
优选的，所述封闭装置为设置在加液壶盖体内的滑动块。这样的结构节省空间，但是在加工时成本较高，加工精度的要求也比较高。
优选的，所述连接柱内对应喷枪进气孔位置还设有单向阀组件，单向阀组件包括紧固在连接柱内的限流套，所述限流套上内侧装有定位座，定位座底部安装有限流套；所述限流套上设有限流小孔，所述单向阀下方和定位座之间形成一个容腔，供小部分液体倒流时的储存，从而防止直接流向单向阀。
这样的结构主要也是为了和加液壶进行配合，防止液体倒流到枪体内部。
优选的，单向阀外套有弹簧，以提高单向阀的密封度。
优选的，所述加液壶底部中间设有凸起部，吸液管的末端对应加液壶底部边缘部分。这样减少使用完毕后的残液余留，避免旧液和新液混合。
优选的，所述加液壶盖体的顶部与枪体的外侧之间还设置有一支撑柱，所述连接柱位于该支撑柱之内，该支撑柱与加液壶盖体、枪体连为一体，以提高加液壶盖体和枪体之间连接的稳固性。
与现有技术相比，本发明的喷枪通过对加液壶盖体上的改良，同时加上配套的封闭装置设置，在不更换加液壶的情况下，就能对加液壶内进行添加原料；此外，在这个过程中还能确保喷枪内部的管道流通，防止添加料到处乱洒。
附图说明
图1是本发明喷枪实施例的整体结构剖视图。
图2是本发明喷枪实施例中单向阀组件的剖视图；
图3是本发明喷枪的整体结构示意图；
图4是本发明喷枪中单向阀组件的结构示意图；
图5是本发明喷枪中单向阀组件的分解结构示意图。
具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
现有技术中，常常需要通过打开加液壶进行加液。但是在连续工作中这样操作非常不方便。而且现有技术中加液壶底的液体很难吸完。
为解决这样的问题，如图1～图5所示，为本发明喷枪的一个优选实施例。该喷枪，包括枪体1、中空的连接柱2、设置在枪体1下方的加液壶4、设置在加液壶4开口上的加液壶盖体3。
连接柱2就设置在加液壶盖体3的顶部与枪体1之间，连接柱2的底端伸入到盖体3下方，连接柱2的底部插配连接有一吸液管42，该吸液管42的末端伸入到加液壶4的底部，吸液管42通过中空的连接柱2使加液壶4和枪体1内部连通。
并且，加液壶盖体3的顶部与枪体1的外侧之间还设置有一支撑柱10，连接柱2位于该支撑柱10之内并与支撑柱10平行相连，该支撑柱10与加液壶盖体3、枪体1连为一体，三者一体成型制造。
加液壶盖体3和加液壶4匹配盖在加液壶4的开口上，加液壶盖体3上方开有加液口41，具体是，加液壶盖体3的顶部向上延伸出有一圈延伸壁31而形成上述的加液口 41，加液口41上设有封闭装置。根据实际需求，封闭装置可选择为与延伸壁31螺纹连接的密封盖32，密封盖32与加液壶盖体3的延伸壁31相适配而能活动启闭地盖合在加液口41处，这样的结构简单，加工方便，使用时只要拧开密封盖就能进行加液。
或者可替代的，封闭装置为设置在加液壶盖体3内的滑动块。滑动块更为隐蔽，使用也很方便。
参见图2、图4和图5，连接柱2内对应喷枪的进气孔位置还设有单向阀组件，单向阀组件包括紧固在连接柱2内的限位套6，限位套6内侧装有定位座5，定位座5底部延伸出限位套6的底部、并且安装有限流套7，限流套7上设有限流小孔71，防止液体倒流；限位套6内安装有单向阀8，单向阀8下方和定位座5之间形成一个容腔，使小部分液体倒流时存在此处，从而防止直接流向单向阀8。单向阀8外套有弹簧9，以提高单向阀8的密封度。这样的设置确保了壶体内的液体不会倒流到枪体内。
加液壶4底部中间设有凸起部，吸液管42的末端对应加液壶4底部边缘部分。这样减少使用完毕后的残液余留，避免旧液和新液混合。
综上所述，本发明和现有技术相比，在确保了喷液效果的前提下，提高了加液壶4加液的效率。只要打开加液口41上设有封闭装置，就能在不卸下加液壶4的前提下进行加液。枪体也能更有效的利用加液壶里的资源，减少了浪费。
