Further limiting, arranging an installation tube on the plane of the lower plug body, communicating an inner hole of the installation tube with the air tube hole, and arranging an installation hole matched with the installation tube at the bottom of the upper plug body; the upper plug body is inserted into the mounting pipe through the mounting hole at the bottom to be connected with the lower plug body, so that the disassembly is more convenient.
Further defined, the upper plug body includes a three-segment plug segment; the top of the three-section plug is smaller in size, and the three-section plug can be suitable for children, teenagers and adults.
Further defined, the upper plug body includes two segments; the two-segment plug can be suitable for teenagers and adults.
Further defined, each slug member is hemispherical; each segment of plug section is hemispherical, so that the plug section is more matched with the shape of nostril, and the sealing performance is better.
Further limiting that the upper plug body and the lower plug body are made of soft silica gel; the upper plug body and the lower plug body are made of soft silica gel materials, so that the upper plug body and the lower plug body are more comfortable to wear in a deformable manner.
Further defined, the plurality of plug segments of the upper plug body are integrally formed.
Further limiting, forming a stepped hole with a small upper part and a large lower part by the inner hole of the mounting tube and the air tube hole; the side wall of the mounting tube can limit the air tube inserted into the air tube hole so that the air tube cannot be inserted too long.
The beneficial effects of the utility model are as follows: the size gradual change can adapt to the crowd of various age groups and carry out the nitric oxide survey to with the very fit of nostril, the leakproofness is better, and children use the testing result more accurate, simple structure, convenient to use.
