Description

Technical Field

[0001] The utility model relates to the technical field of smoke meter equipment, in particular to a handheld transmission smoke meter. Background Art

[0002] The smoke meter is used to monitor vehicle exhaust emissions, and is mainly used to measure exhaust gas from diesel engines. A piston pump is used to extract a certain volume of exhaust gas from the exhaust pipe of the diesel engine at a specified time, and it is passed through a filter paper of a certain area. The smoke particles in the exhaust are trapped on the filter paper and dye the filter paper black. The absorbance of the filter paper is measured with a photoelectric measuring device, and the absorbance indicates the degree of smoke in the exhaust.

[0003] Traditional smoke meters are large and inconvenient to carry, and monitoring requires inserting sampling equipment into the vehicle exhaust pipe, which is time-consuming and labor-intensive, and has low detection efficiency. Therefore, handheld transmission smoke meters have emerged, which can quickly detect vehicle exhaust emissions by hand without complicated operations, greatly improving detection efficiency. However, existing handheld transmission smoke meters not only have a display screen for displaying detection data, but also have the function of connecting to a mobile terminal to transmit data. The user holds the transmission smoke meter with one hand and uses the other hand to take notes and use the mobile terminal, which is inconvenient. Therefore, it is necessary to design a mounting structure that can install a fixed mobile terminal and combine it with the handheld smoke meter, which is easy to use and can simultaneously view the data transmission status and detection results of the display screen and the mobile terminal, further improving the detection efficiency and freeing up the other hand.
