In this way, the dirt adsorbed by the first suction tray 03 can be filtered in the second filter 08 by the filtering action of the second filter 08, so that the dirt is prevented from entering the first vacuum generator 02 and causing the blockage of the suction end of the first vacuum generator 02.

In order to clean the dirt in the second filter 08, the two ends of the second filter 08 are detachably connected with the first suction disc 03 and the first vacuum generator 02. In addition, in order to facilitate the detachment of the second filter 08, the connection of both ends of the second filter 08 to the first suction tray 03 and the first vacuum generator 02, respectively, may be achieved by quick joints.

Furthermore, two ends of the second filter 08 can be connected with a pressure difference meter so as to observe the pressure difference between the two ends through the pressure difference meter, and then determine the blocking condition of the second filter 08 through the pressure difference, so as to avoid the adsorption effect on the dirt in the holes or seams of the electronic product when the second filter 08 is seriously blocked.
