Technical Problem
[0004]为了克服上述现有技术的缺点，本发明的目的在于提供一种侧光式荧光传感器，解决的问题之一在于传感单元不易更换而导致清洁困难，同时体积大、封装困难的问题；解决的问题之二在于，不易阵列化设计从而导致灵敏度不高的技术问题
Benefits of technology
[0029]本发明的侧光式荧光传感器通过设置一体化成型的传感器壳体，将荧光敏感单元封装于传感器壳体上部，将光电系统封装于传感器壳体下部，将激发光源设置于传感器壳体一侧，激发光源能够从壳体一侧耦合射向荧光敏感单元，并在荧光敏感单元的作用下，使激发光从制备有荧光薄膜的一侧出射，实现侧光式激发传感。本发明的侧光式荧光传感器一方面，由于传感器壳体的上、下两端分别可拆卸的设置荧光敏感单元封装盖(上封盖)和传感器封装盖(下封盖)，在需要进行清洁时，只需拆卸传感器壳体上端的荧光敏感单元封装盖，取出敏感单元对进行清洁，十分方便，有效增加了传感器零部件的使用寿命达到节约耗材的目的；另一方面，荧光敏感单元载体封装盖通过密封胶圈与敏感单元密封形成传感气室，荧光敏感单元封装盖(上封盖)既是传感器气室的构成部分，也是本发明的主要气体通道，使整个传感器的光电器件更加紧凑，气密性更好。同时可以看出，本发明在传感器壳体内上部分为荧光敏感单元，下部分为光电传感器部分，一体化的荧光传感器壳体设计使得本发明结构紧凑，体积小，携带方便，使用便利。

Abstract
The application discloses a side light type fluorescent sensor and belongs to the technical field of fluorescent sensor sensing. The sensor shell is integrally formed, the fluorescent sensitive unit is packaged on the upper portion of the sensor shell, the photoelectric system is packaged on the lower portion of the sensor shell, and the excitation light source is arranged on one side of the sensor shell; the excitation light source can be coupled to the fluorescent sensitive unit from one side of the shell, and under the action of the fluorescent sensitive unit, the excitation light is emitted from the side where the fluorescent film is prepared, so that the side light type excitation sensing is realized; the integrally formed fluorescent sensor shell design makes the application compact in structure, small in size, convenient to carry, convenient to use on a terminal, simple to replace the sensitive unit, saves materials, good in air tightness and easy to be arrayed.
