The second filter layer 20 is a non-woven structure layer. For example, the second filter layer 20 can also be a non-woven structure of a Teflon material extension film having a specific filtering property through a specific processing process. It should be understood that the non-woven structural layer of the second filter layer 20 may also be selected from other materials such as natural plants or other synthetic fibers. In other embodiments, the second filter layer 20 may also be an electrostatic filter fiber layer. For example, the second filter layer 20 may be, for example, a statically processed melt-blown nonwoven filter layer, and the second filter layer 20 Electrostatic electricity is imparted to the filter layer fibers, and the fine dust of the toner passing through the second filter layer 20 is captured by the electrostatic dust collection principle. For the filtration effect of toner dust, it can improve the effect. Preferably, the thickness of the second filter layer 20 is smaller than the thickness of the first filter layer 10, and when the second filter layer 20 has a second aperture smaller than the diameter of the first aperture, the airflow flows through the The second filter layer 20 has a greater resistance than the first filter layer 10, so reducing the thickness of the second filter layer 20 can relatively reduce the resistance of the airflow, thereby helping to increase the internal airflow of the server 5. The convection efficiency with the external airflow causes the heat dissipation efficiency of the transaction machine 5 to be relatively increased to reduce the probability of failure of the transaction machine 5.
