Description

一种可测量饮水量的水壶
技术领域
本发明涉及一种饮水设备，尤其是涉及一种水壶。
背景技术
在智能饮水领域，有时会涉及到饮水量的监测，现有技术中饮水量的测量通常通过液体流量计实现，目前常见的液体流量计包括差压式流量计、转子流量计，容积式流量计、电磁式流量计与超声波流量计等，其均是直接测量流经饮水设备出水口处的液体流量，然后这种方式具有若干缺陷，如对于差压式流量计、转子流量计与容积式流量计而言，因为与液体直接接触的结构难以清洗，故流量计很容易滋生细菌，从而给用户带来健康隐患。对于电磁式流量计与超声波流量计而言，虽然电磁式流量计与超声波流量计不存在难以清洗的结构，但是电磁式流量计无法测量纯净水的流量（纯净水的电导率过小，无法作为导体切割磁感线而产生稳定的感应电势差），而超声波流量结构复杂，体型较大，且成本较高，难以应用在内部空间紧凑的饮水设备上。
发明内容
为了克服现有技术的不足，本发明提供一种可测量饮水量的水壶，采用测量气体体积的方式间接测量饮水量，测量装置不与水发生直接的接触，从而有效地解决了液体流量计难以清洗而带来的细菌滋生的问题；同时，由于出水口没有任何测量装置，故不会对水的流动造成阻碍，从而使用户的饮用动作更加流畅；测量精度高，结构简单，易于实现。
本发明解决其技术问题所采用的技术方案是：
一种可测量饮水量的水壶，包括壶体，壶体内部具有一用于储水的腔体，壶体上设有与腔体连通的出水口与进气口，进气口处密封连接有气体流量计，且水壶满足设置：由气体流量计进入腔体内的气体的体积等于由出水口流出的水的体积。
作为上述方案的进一步改进方式，包括与气体流量计串联的单向阀，单向阀仅允许空气自外界向腔体内流动。
作为上述方案的进一步改进方式，包括吸管，吸管插接在出水口内并与出水口密封连接，该吸管的一端伸出出水口，另一端伸入腔体并直至腔体的底部。
作为上述方案的进一步改进方式，气体流量计为容积式气体流量计。
作为上述方案的进一步改进方式，气体流量计为刮板式流量计或齿轮式流量计。
本发明的有益效果是：
采用测量气体体积的方式间接测量饮水量，测量装置不与水发生直接的接触，从而有效地解决了液体流量计难以清洗而带来的细菌滋生的问题；同时，由于出水口没有任何测量装置，故不会对水的流动造成阻碍，从而使用户的饮用动作更加流畅；测量精度高，结构简单，易于实现。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明第一个实施例的示意图；
图2是本发明第二个实施例的示意图。
具体实施方式
以下将结合实施例和附图对本发明的构思、具体结构及产生的技术效果进行清楚、完整的描述，以充分地理解本发明的目的、方案和效果。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，如无特殊说明，当某一特征被称为“固定”、“连接”在另一个特征，它可以直接固定、连接在另一个特征上，也可以间接地固定、连接在另一个特征上。此外，本发明中所使用的上、下、左、右等描述仅仅是相对于附图中本发明各组成部分的相互位置关系来说的。
此外，除非另有定义，本文所使用的所有的技术和科学术语与本技术领域的技术人员通常理解的含义相同。本文说明书中所使用的术语只是为了描述具体的实施例，而不是为了限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的组合。
参照图1，示出了本发明一个实施例的示意图，包括壶体1，壶体1的内部具有一用于储水的腔体，壶体1上还设有与腔体连通的出水口11与进气口12，进气口12处设有气体流量计2，气体流量计2与进气口1密封连接，以保证气体仅能通过气体流量计2进入腔体内部。
当腔体内的水从出水口11流出后，腔体内的气压会随之降低，在大气压的作用下，外界空气会补入至腔体内部，且补入的气体体积必然等于流出的水的体积，故通过气体流量计测量气体的体积便能间接得知用户的饮水量。因为流量计不与水发生直接接触，故可以有效地解决常规测量方式中液体流量计难以清洗而带来的细菌滋生的问题，同时，由于出水口没有任何测量装置，故不会对水的流动造成阻碍，从而使用户的饮用动作更加流畅。
本实施例中的壶体可以仅包括出水口11与进气口12，用户在使用时首先倾倒壶体保证水漫过出水口11，然后通过吮吸或者挤压壶体的形式迫使水流出。
此外，为了便于用户饮用，本发明还公开了第二种实施例，参照图2，本实施例中水壶还包括有吸管3，吸管3插接在出水口11内并与出水口11密封连接，该吸管的一端伸出出水口，另一端伸入腔体并直至腔体的底部，因为吸管直接伸入至液面下，故用户无需倾倒壶体便可以直接进行饮用。
优选的，还包括与气体流量计2串联的单向阀4，单向阀4仅允许空气自外界向腔体内流动，其可以实现腔体与外界环境的气压平衡，进一步减少用户在饮水时的阻力。
出于测量精度以及体积、成本等方面的考虑，气体流量计优选为容积式气体流量计，更优选为刮板式流量计或齿轮式流量计。
以上是对本发明的较佳实施进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可做出种种的等同变形或替换，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。
