Abstract: The present invention relates to an air filtering system capable of enhancing inspection convenience, which is disposed in the ceiling and comprises a housing, a filter, a first sampling tube, and a second sampling tube. On both ends of the housing, an intake and an outtake are disposed opposite to each other. The filter is disposed in the housing, and has an intake surface and an outtake surface opposite to each other. The filter divides the inner space of the housing into a first sampling zone and a second sampling zone. A first end of the first sampling tube is fixed on the housing, and communicates with the first sampling zone. Likewise, a first end of the second sampling tube is fixed on the housing, and communicates with the second sampling zone. Besides, a second end of the first sampling tube and a second end of the second sampling tube are both fixed on the wall. Thereby, the inspection convenience for the inspection staffs can be enhanced.

Abstract: A protective clothing with ventilation effect is revealed. The protective clothing includes an airproof protection portion and a plurality of ventilation portions. A periphery of each ventilation portion is connected to the airproof protection portion. Each ventilation portion includes a filter material. Heat and moisture inside the protective clothing can be removed by air flowing in and out through the ventilation portions while wearing the protective clothing. Thus uncomfortable feeling is reduced and working efficiency is improved. As to the filter material of the ventilation portion, it is used to filter while air flowing. Thus the protective clothing still provides users high-level protection beside the ventilation effect.

Abstract: An auxiliary feed-in mechanism comprises a base having two rails on two sides of the base respectively and a crossrod across two rails on another side of the base; a driving mechanism having a dynamic retractable rod and a chassis, one end of the dynamic retractable rod hinging with one side of the crossrod, another end of the dynamic retractable rod connecting to one side of the chassis, the chassis setting on two rails; a power mechanism setting under the chassis, a driving shaft of the power mechanism penetrating the chassis to expose above the chassis; a delivering mechanism having a frame and a plurality of rollers, the rollers setting side by side in the frame, the delivering mechanism setting above the chassis, a bottom of the frame connecting to the driving shaft, the auxiliary feed-in mechanism can increase the working efficiency of the examining mechanism.

Abstract: A sampling pipe suitable for sampling materials in a channel is disclosed. The sampling pipe includes a hollow body and a plurality of openings. The hollow body has a plurality of sampling sections, and these sampling sections are suitable for being disposed in the channel. The openings penetrate through the outer wall of the hollow body and locate in the sampling sections. Wherein, there is at least one opening in each sampling section, and flux of materials flowing into each sampling section is the same.
