Description

便携式多参数水质检测器 技术领域
本发明涉及水质检测装置领域，尤其涉及 一种 便携式多参数水质检测器 。
背景技术
水是生命之源，随着水污染问题的越来越严重，人们对日常的饮水安全关注度也逐渐升高。因此越来越多的家庭安装了家用反渗透式净水器。但是目前尚没有一种有效的方法评估净水器出水的净化效果。这带来一个问题是消费者无法有效评估净水器的净化效果，以及无法准确判断需要更换滤芯的时间。
目前，某些高端定位的净水器加装了水质TDS（溶解性总固体）检测器用来评估水质的净化效果。然而TDS指标反映的是水中电离的离子的浓度，而这些阴阳离子的多少并不能直接反映与水质优劣，如纯净水的TDS相对于矿泉水是低的，但并不代表矿泉水的水质就是差的。而国家标准中对于水质检测有106项指标，其中有30多项指标是与水体的有机物污染相关。因此通过判断水质有机物指标去评价水质优劣更有现实意义。
其中，TOC（总有机碳）和COD（化学需氧量）是反映水体有机物污染的两项重要指标。过去水质检测过程中主要采用电化学分析水质监测技术来测量这两项水质参数，然而，这种方法存在测量周期长、测量复杂，所需化学原料多等缺点，给实际操作带来诸多不便。
近几年来，光谱分析技术在水质监测中的应用异军突起，相较于电化学分析技术而言，光谱分析技术具有成本低、携带方便、分析速度快、无二次污染、无需化学试剂及可实现多参数测量等众多优点。因此，现有技术存在缺陷，需要改进。
 技术问题
本发明的目的是克服现有技术的不足，提供一种便携式多参数水质检测器。

进一步地，所述PCBA板上设有显示器、处理器和通讯设备，所述显示器和通讯设备分别与处理器连接。
进一步地，所述水质传感器采用光谱检测方式检测，能检测的水质参数包括TOC、COD、TURB、色度、TDS及NO3-N ，水质传感器采集到水质数据后发送给PCBA板中的处理器，处理器再将这些数据显示在显示器上 。
进一步地，所述外壳上与显示器对应位置还设有透明玻璃视窗，通过该透明玻璃视窗可看见显示器上的数据。
进一步地，所述通讯设备的通讯方式为无线通讯，所述无线通讯方式选自蓝牙、WIFI、3G中一种或多种，此处选择蓝牙无线通讯方式，通过蓝牙通讯设备可将水质参数传送到客户端。
进一步地，所述外壳上还设有水位线，手持便携式多参数水质检测器，让被测溶液从下盖的入水口进入水质传感器，被测液体的水界面没过外壳上的水位线即可对被测液体的水质进行检测。
 有益效果
采用上述方案，本发明提供一种形态小巧，结构简洁，操作简便的便携式多参数水质检测器，可放入任意深度被测液体中检测，而不影响便携式多参数水质检测器性能。本发明采用光谱分析技术，可快速实现多种水质参数测量，无需化学试剂，无污染，是一种真正环保、低成本的水质检测装置。
 附图说明
图1为本发明的拆解图；
图2为本发明的剖视图；
图3为本发明的使用状态图。
 本发明的实施方式
以下结合附图和具体实施例，对本发明进行详细说明。
参照图1至图3所示，本发明提供一种便携式多参数水质检测器，包括：外壳、水质传感器2、PCBA板、软管3和电池4；所述水质传感器2、PCBA板5、软管3和电池4均设置在外壳内部。所述水质传感器2和电池4还分别与PCBA板5电性连接。
所述外壳包括上盖13、主壳12和下盖11，上盖13和下盖11分别与主壳12密封衔接，下盖11底部设有一入水口，上盖13顶部设有一出气口。所述水质传感器2上、下方分别设有出气口和入水口。其中，下盖11的入水口通过密封圈与水质传感器2下方的入水口密封装配；水质传感器2上方的出气口与软管3一端衔接，软管3的另一端再与上盖13的出气口密封衔接。
所述PCBA板5上设有显示器、处理器和通讯设备，所述显示器和通讯设备分别与处理器连接。所述通讯设备的通讯方式为无线通讯，所述无线通讯方式选自蓝牙、WIFI、3G中一种或多种，此处选择蓝牙无线通讯方式，通过蓝牙通讯设备可将水质参数传送到客户端。
所述水质传感器2采用光谱分析技术，手持便携式多参数水质检测器检测水杯6中的水质时，将被测溶液从下盖11的入水口进入水质传感器2内部的腔体内，水质传感器2向侵入自身腔体内部的被测液体发射检测光，并接收穿过被检测液体的反射光，水质传感器2通过对被检测液体的反射光的光谱进行分析，从而得到被测液体的水质参数。水质传感器2还能检测被测液体的温度，从而对所测量的水质参数进行修正。
须注意的是，所述主壳12上还设有水位线122，手持便携式多参数水质检测器检测水质时，需要将被测液体的界面没过外壳上的水位线122，让水质传感器2充分浸没在被测液体当中，即可对被测液体的水质进行检测。由于水质传感器2上端通过一软管3连接壳体外部，因此，可将便携式多参数水质检测器放入被测液体中任意深度，而不影响便携式多参数水质检测器性能。
水质传感器2能检测包括TOC、COD、TURB、色度、TDS及NO3-N在内的多种水质参数，水质传感器2采集到水质数据后发送给PCBA板5中的处理器，处理器再将这些数据显示在显示器上。所述主壳12上与显示器对应位置设有一个透明玻璃视窗121，通过该透明玻璃视窗121可直观获得显示器上显示的数据。
相对于过去水质检测过程中采用电化学分析水质监测技术测量而言，本发明采用光谱分析技术，具有成本低、携带方便、分析速度快、无二次污染、无需化学试剂及可实现多参数测量等众多优点。
综上所述，本发明提供一种形态小巧，结构简洁，操作简便的便携式多参数水质检测器，可放入任意深度被测液体中检测，而不影响便携式多参数水质检测器性能。本发明采用光谱分析技术，可快速实现多种水质参数测量，无需化学试剂，无污染，是一种真正环保、低成本的水质检测装置。
以上仅为本发明的较佳实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
