Pneumatic control controller triggered by pneumatic control button and used for extracting odor

CUI LIXING / DENG YONGFENG

The invention relates to a pneumatic control controller triggered by a pneumatic control button and used for odor extraction. The pneumatic control controller comprises a shell and an execution control assembly installed in the shell. A control interface, an air interface, an input interface and an output interface are formed in the outer side wall of the shell; the execution control assembly comprises an upper valve core assembly, a middle valve core assembly and a lower valve core assembly which are intermittently communicated with the input interface and the output interface through the air pressure change of the control interface; the controller is suitable for a vacuum closestool with an odor pumping function and a vacuum closestool with an odor pumping and flushing two-in-one function, solves the problems of odor pumping and toxin expelling through inching control, adopts an integrated structural design, and is few in parts and high in reliability; the control interface is used for being connected with the control button, the air pressure change at the control interface is achieved, the execution control assembly moves, then the input interface and the output interface are intermittently communicated, and due to the fact that the input interface is used for being connected with a vacuum source, effective odor pumping action can be achieved.

本发明涉及一种气控按钮触发的抽臭气用气控控制器，包括壳体、以及安装在壳体内部的执行控制组件；所述壳体外侧壁处设置有控制接口、空气接口、输入接口及输入接口；所述执行控制组件包括通过控制接口的气压变化间歇性的连通输入接口与输入接口的上阀芯组件、中阀芯组件及下阀芯组件；本发明适用于带抽臭气功能的真空马桶，以及具有抽臭气和冲水二合一功能的真空马桶，通过点动控制解决抽臭气及排毒的问题，采用一体式结构设计，零部件少，可靠性高；控制接口用于与控制按钮连接，实现控制接口处气压变化，使得执行控制组件发生运动，进而间歇性的连通输入接口与输入接口，由于输入接口用于与真空源连接，即能实现有效的抽臭气动作。
