| titleOfInvention | Filter membrane for atmospheric fine particulate matter detection device |
| abstract | The utility model provides a filter membrane for an atmospheric fine particle detection device, which at least comprises a filter membrane body and a frame; the frame is arranged on the outer edge of the filter membrane body; the top surface of the frame is an inclined surface; the filter membrane body comprises a coarse filter membrane layer and a fine filter membrane layer; the upper surface of the coarse filter membrane layer is provided with first filter membrane hair; a space is reserved between the coarse filter membrane layer and the fine filter membrane layer; the lower surface of the third fine filter membrane layer is a smooth surface, and the upper surface of the third fine filter membrane layer is provided with fourth filter membrane bristles; through the setting of above-mentioned structure, be favorable to increasing the entrapment rate of air particulate matter at the filter membrane layer, the filter membrane easily takes place technical problem such as micropore jam when gathering fine particles thing among the solution prior art. |
