Detailed Description

The present application is further described below with reference to the accompanying drawings and examples.

Examples

An odor sampling bottle with a balance pressure bag as shown in fig. 1 to 4 comprises an odor sampling bottle 1 and a balance pressure bag 2.

The odor sampling bottle 1 comprises a bottle body 11, one end of the bottle body 11 is provided with a first extension part 12, one end of the first extension part 12 is provided with a first extension pipe 121, one end of the outer periphery of the first extension pipe 121 is provided with a connecting pipe 13 for connecting with vacuum-pumping equipment, one end of the first extension pipe 121 is provided with a straight-insertion air plug 14, the other end of the bottle body 11 is provided with an air collecting port 15, a rubber plug 16 is assembled in the air collecting port 15, a first barometer 161 is arranged in the rubber plug 16 in a penetrating manner, meanwhile, the rubber plug 16 is also used for penetrating an injector for sampling, and the outer periphery of one end of the bottle body 11 is provided with a round hole 17;

the balance pressure bag 2 is embedded in the odor sampling bottle 1, and comprises a bag body 21 arranged in the bottle body 11, one end of the bag body 21 is provided with an air pipe 22 penetrating through the round hole 17, the periphery of the air pipe 22 is penetrated with a second barometer 23, one end of the air pipe 22 is provided with a four-way pipe 24, four openings of the four-way pipe 24 are arranged vertically in pairs, one opening of the four-way pipe is assembled at one end of the air pipe 22, a butterfly-shaped head air plug 25 is penetrated in two openings vertical to the air pipe 22, and one opening end of the four-way pipe 24 is provided with a second extension pipe 26.
