AI Technical Summary
Technical Problem
In existing control valves with liquid reservoirs, the compression springs have a reduced service life because they need to provide restoring force for the extension and retraction of both the valve core and the valve body.
Method used
A second elastic element is provided between the valve body and the liquid storage box to assist the extension and retraction of the first elastic element, reduce its deformation, and extend its service life.
Benefits of technology
The use of a second elastic element improves the service life of the first elastic element, reduces the degree of deformation, and extends the overall service life of the control valve.

Abstract
本发明公开了一种储液盒的导液结构及投放装置。包括设于储液盒投放口处的控制阀，控制阀包括阀壳，阀壳内部中空形成导液流道，导液流道内设同轴的阀芯，阀芯与阀壳之间设有第一弹性件，阀壳通过第二弹性件可伸缩地安装于储液盒上；通过在阀壳与储液盒之间设第二弹性件，使得在洗涤剂盒推弹导液过程中，第二弹性件辅助第一弹性件伸缩，提高第一弹性件的使用寿命。还提供一种投放装置，具有至少一个插接槽，投放结构包括安装于插接槽内的储液盒，还包括导液管和导液结构，导液管的一端经储液盒的投放口插入阀壳内与导液流道连通。
