The invention relates to a multifunctional clean filtering terminal, which comprises a medium or high efficiency filter, a stainless steel box body, an air inlet, an air outlet and an air outlet, and is characterized in that the medium or high efficiency filter is arranged on the stainless steel box body; the epidemic prevention switching valve is arranged at the other air inlet of the stainless steel box body and is used for closing or opening the air inlet; the disinfection module is arranged in the air duct at the rear end of the medium-efficiency or high-efficiency filter and is used for internally disinfecting and purifying inlet air; and the controller is respectively connected with the medium or high-efficiency filter, the disinfection module and the epidemic prevention switching valve, and is used for controlling the medium or high-efficiency filter, the disinfection module and the epidemic prevention switching valve to realize switching between an exhaust purification working condition and a non-exhaust purification working condition. The problem that the maintenance cost of a filter of a conventional exhaust system is high is solved, the filter has an epidemic prevention switching function, the design conforms to the design specification of a negative pressure isolation ward, meanwhile, the filter also has an internal disinfection function, and the risk that an operator is in direct contact with pollutants is avoided.

    本发明涉及一种多功能洁净过滤末端,包括:中或高效过滤器,设置在不锈钢箱体的一个进风口,用于净化室内排风;平疫切换阀,设置在在不锈钢箱体的另一个进风口,用于关闭或开启该进风口;消毒模块,设置在中或高效过滤器后端的风道内,用于内部消毒净化进风;控制器,分别连接中或高效过滤器、消毒模块和平疫切换阀,用于控制中或高效过滤器和消毒模块以及平疫切换阀,实现排风净化工况和非排风净化工况之间的切换。本发明降低了过往排风系统过滤器维护成本高的问题,具备平疫切换功能,设计符合负压隔离病房设计规范,同时兼具内部消毒功能,避免了操作人员直接接触污染物的风险。
