The self-cleaning box-type vehicle-mounted air filter comprises a box-type shell, a plate-type filter element and a self-cleaning unit, the plate-type filter element is obliquely installed in the box-type shell, an air inlet is formed in one end of the box-type shell, an air outlet is formed in the other end of the box-type shell, and an ash discharging opening is formed in the bottom of the box-type shell; the self-cleaning unit comprises a reciprocating lead screw, an energy accumulator, a pulse injection valve, a strip-shaped nozzle and a driving device capable of driving a lead screw of the reciprocating lead screw to rotate through a transmission mechanism, the pulse injection valve is fixedly connected with a sliding block of the reciprocating lead screw, an air inlet connector of the energy accumulator is communicated with an air source on the vehicle, and the energy accumulator, the pulse injection valve and the strip-shaped nozzle are sequentially communicated through a pipeline. And the strip-shaped nozzle is fixedly connected with the pulse blowing valve and is over against one side, far away from the air inlet, of the plate-type filter element. According to the self-cleaning box type vehicle-mounted air filter, self-cleaning of the air filter is achieved, dust in the filter element can be automatically removed, and the filter element is prevented from being blocked.
本发明公开了一种自清洗的箱式车载空气过滤器,包括箱式壳体、板式过滤滤芯和自清洗单元,板式过滤滤芯倾斜安装在箱式壳体的内部,箱式壳体一端设置有进风口、另一端设置有出风口,箱式壳体的底部设置有排灰口;自清洗单元包括往复丝杠、蓄能器、脉冲喷吹阀、条形喷嘴和能够通过传动机构驱动往复丝杠的丝杆转动的驱动装置,脉冲喷吹阀与往复丝杠的滑块固连,蓄能器的进气接口与车辆上的气源连通,蓄能器、脉冲喷吹阀及条形喷嘴依次管路连通,且条形喷嘴与脉冲喷吹阀固连,条形喷嘴正对板式过滤滤芯远离进风口的一侧。本发明的自清洗的箱式车载空气过滤器实现了空气过滤器的自清洗,能够自动清除滤芯中的灰尘,防止滤芯堵塞。
