Description

Technical Field

[0001] The present application relates to the technical field of air conditioning filters, and in particular to an air conditioning filter for ventilation of motor vehicles. Background Art

[0002] EMU, the full name of which is power vehicle, refers to vehicles equipped with power devices in rail transit systems, including locomotives and power cars. EMUs are equipped with driving wheels, while the corresponding vehicles without driving devices are trailers. To increase passenger comfort, each EMU is equipped with multiple air conditioners, and dust filters are installed on the air conditioner outdoor units. The air conditioning filters of EMUs are installed on the roof of the EMU.

[0003] Traditional EMU air conditioning filters have large mesh sizes. When the EMU finishes a day's journey, professional staff are needed to check the air conditioning filters and clean them effectively. When the EMU is stopped, the filter mesh sizes are large and cannot adsorb and filter fine particles. Therefore, EMUs with multiple carriages need staff to check and clean them one by one, which increases the workload and difficulty of operation. Utility Model Content
