具体实施方式
下面结合附图和具体实施例对本发明进行详细说明。本实施例以本发明技术方案为前提进行实施，给出了详细的实施方式和具体的操作过程，但本发明的保护范围不限于下述的实施例。
如图1和图2所示，本实施例提供了一种无内水箱饮水机，包括外置水箱100 和饮水机本体，外置水箱100设置于饮水机本体的后端。饮水机本体包括通过管道依次连接的水冷散热模块200、复合滤芯300、加热体400和出水机构500；外置水箱100连接水冷散热模块200。水冷散热模块200和复合滤芯300之间的管道上设有水泵700和温度传感器；复合滤芯300和加热体400的管道上依次设有单向阀、电磁控制阀和流量计；加热体400和出水机构500之间的管道上设有温度传感器。
如图3所示，外置水箱100包括水箱主体101和盖体102，盖体102固定在水箱主体101的顶部，盖体102的一端伸出水箱主体101的顶面，并向水箱主体101的底部弯折，形成一端开口的遮蔽腔103；水箱主体101的顶部设有加水口1011，底部设有出水阀门1012，加水口1011位于遮蔽腔103内。
本实用新型分别通过水箱主体101顶部的加水口1011进水，通过水箱主体101底部的出水阀门1012放水，保证了进水和出水效率；本实用新型还在水箱主体101的顶部设置盖体102，该盖体102对加水口1011形成遮蔽，有利于避免空气中的灰尘二次落入水箱中污染水源，并且盖体102向水箱主体101底部弯折的区域还可用于作为提手，功能丰富且结构精简。具体地，水箱主体101的底部设有隔板1013，该隔板1013包括隔板主体1013a和安装管1013b，隔板主体1013a设有出水口，安装管1013b连接出水口，并位于隔板主体1013a的底部，出水阀门1012安装在安装管1013b内。如图5所示，出水阀门1012包括凸起件1012a、连接弹簧1012b和封闭板1012c，封闭板1012c固定在凸起件1012a的顶端，并与隔板主体1013a平行，凸起件1012a的底部侧面向安装管1013b的管壁延伸，直至与安装管1013b的内管壁抵接，连接弹簧1012b缠绕在凸起件1012a外侧，连接弹簧1012b的一端连接隔板1013，另一端连接凸起件1012a的底部。如图3和图4所示，外置水箱安装在饮水机上时，将凸起件1012a向上顶出为打开状态，水箱离开饮水机后出水阀门1012为闭合起到密封状态，这样即挡灰尘也有美观的作用。水箱主体101设有可拆卸连接部，用于通过该可拆卸连接部与饮水机对应的可拆卸连接配合部相配合，构成可拆卸连接，可拆卸连接的方式可以为卡接和磁接。可选的，水箱主体101的内部空间从顶部到底部逐渐增大，使得底部容水更多，整体更加稳定。可选的，水箱主体101远离进水口的一侧设有凸起的折边1016，可饮水机进行固定，起到卡位固定的效果。
作为一种优选的实施方式，水箱主体101的顶部设有定位凸起1015，盖体102对应设有定位凹槽102a，定位凸起1015与定位凹槽102a的形状和大小相配合； 通过设置定位凸起1015和定位凹槽102a便于外置水箱和盖体102之间的定位，且能提升外置水箱和盖体102之间连接的稳定性。可选的，盖体102远离加水口1011的一端连接有侧板102b，该侧板102b贴合水箱主体101的侧边，并与水箱主体101固定连接。
作为一种优选的实施方式，水箱主体101内还设有水位检测组件1014，该水位检测组件1014通过开关电路接入水泵700的供电电路。具体地，水位检测组件1014包括封堵塞1014a、导向通道1014b、浮子1014c和液位传感器，导向通道1014b固定在水箱主体101内，导向通道1014b的一端连接水箱主体101，另一端连接封堵塞1014a，浮子1014c位于导向通道1014b内，液位传感器的探测端正对导向通道1014b的底部，用于探测浮子1014c；通过液位传感器检测外置水箱内的水量起到保护机器防止水泵700干抽，从而防止烧毁电气件的效果。
如图6所示，水冷散热模块200包括导热单元201和进出水接头204，将其接入复合滤芯300和外水箱100连接的管道上，具体结构如下：

作为一种优选的实施方式，滤芯出水口303内设有单向阀，该单向阀连接饮水机，单向阀由电磁阀来作为控制，其单向阀在机器停止工作的时候将出水处密封，起到及时止水功能。
作为一种优选的实施方式，滤芯外瓶301的底部设有第一装配件308和第二装 配件309，第一装配件308的外壁与滤芯外瓶301的内壁形状相配合，第一装配件308固定在滤芯外瓶301内部，并支撑过滤组件，第一装配件308的外壁与滤芯外瓶301的内壁卡接，第二装配件309与滤芯外瓶301的外壁卡接，第一装配件308连接第二装配件309。第一装配件308的外壁设有卡接部，滤芯外瓶301内部对应设有卡接配合部，卡接部和卡接配合部为卡接凸起301a和卡接凹槽308b的组合。滤芯外瓶301的底部外侧设有环形凹槽302b，第二装配件309对应设有环形凸起309a，该环形凸起309a与环形凹槽302b相配合。第一装配件308与第二装配件309之间优选为可拆卸连接，可拆卸连接的方式可以为卡接、螺接或磁接。
本实施例中，采用螺接的连接方式，具体为：第一装配件308的中部设有螺纹槽，第二装配件309的中部对应设有螺接通孔，第二装配件309通过螺栓310经过螺接通孔和螺纹槽连接第一装配件308。

本实施例中，加热体400是采用多组发热丝缠绕其圆形金属部件上，部件表面将附着一层耐高温又绝缘的复合材料。加热体400将安装在一个立体形状金属零件内，其金属零件上有安装多个温度控制器，将加热体400的温度控制在一个合理并安全范围，其多组发热丝将实行分段控制电路。这样即保护产品安全又能起到控制温度的精准性。
如图9和图10所示，出水机构500包括由上盖501a和下壳体501b组成的盒体501，下壳体501b为一个顶面开口的腔体，上盖501a安装并覆盖于腔体顶面开口，形成密闭的结构。在下壳体501b的腔体内设有机构进水口502、主出水口503，引导斜坡504、引导挡板505和缓冲柱506。
如图10所示，机构进水口502设置于盒体501的下壳体501b的后端，主出水口503设置于盒体501的前端中央，机构进水口502和主出水口503之间通过引导斜坡504连接。在引导斜坡504的两侧设有引导挡板505，两侧的引导挡板505向主出水口503收拢，引导斜坡504上靠近机构进水口502的附近设有缓冲柱506，缓冲柱506正对机构进水口502的出口。缓冲柱506可采用圆柱形或等腰三角柱形，当为等腰三角柱形时，其中线朝向机构进水口502的中央，本实施例优选采用圆柱形。通过该结构，当水流从机构进水口502进入出水机构500后，首先会被缓冲柱506分流为两股，分成两股的水流分别沿着引导挡板505流向主出水口503，使得 小流量的水流更加顺滑，而大流量的水流减小和避免湍流的形成，保持出水的畅通。优选的，主出水口503为漏斗形状，便于引导挡板505上两股水流的汇集。此外，出水机构500整体采用混合有无机银离子抗菌粉的塑料制成，可以起到抑菌消毒的作用。
作为一种优选的实施方式，下壳体501b两侧的引导挡板505与盒体501的侧壁之间形成两个排气腔507，引导挡板505的顶部距离盒体(即上盖501a)一定间距。在排气腔507的底部设有排气孔508。当高温水进入出水机构500后，其产生的水汽能够从经过排气腔507从排气孔508流出，减小水中的气泡，提高出水效率。同时，排气腔507和排气孔508能避免水流和大气产生静压，确保出水机构500内部的水完全从主出水口503流出，避免出水机构500内部积水。
本实施例中，盒体501的底部设有辅助出水口509，辅助出水口509位于下壳体501b的前端，上方被出水挡板510包围。出水挡板510的顶部距离盒体501的顶板一定间距。当水流较小时，内部的水流直接从主出水口503流出；当水流较大时，出水机构500内的水流会聚集超过出水挡板510，然后从辅助出水口509共同流出，实现大流量出水的通畅稳定。如图11和图12所示，主出水口503的下方连通出水管道511，在出水管道511的外圈设有环形的集流通道512，排气腔507连接集流通道512。通过该结构，辅助出水口509和主出水口503通过出水管道511和集流通道512汇集，形成一股水流，提高使用者用水的使用和体验。
作为一种优选的实施方式，集流通道512的出口处设有朝向出水管道511的倾斜挡边13，使得辅助出水口509和主出水口503更容易汇集为一条水流。
作为一种优选的实施方式，为了提高结构的紧凑性和密封性，排气孔508也连通集流通道512，避免在盒体501上进行额外开孔排气。
综上，出水机构500将采用特殊结构布局设计和多种组合分体结构，从而实现无论是在哪个温度的水温度可以流畅而有序的快速将干净的饮用水流出。在普通流量下，水流被缓冲柱506均匀的分配为两股，沿着两侧的引导挡板505想主出水孔流出。如进水量大于出水量时，出水机构500内的水流会聚集超过出水挡板510，然后从辅助出水口509流出，和主出水孔的水流快速混合共同流出，确保水流平稳畅通。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本发明的构思作出诸多修改和变化。因此，凡本技术领 域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
