Embodiment 1

[0043] Such as Figure 1 to Figure 3 Shown, a kind of air detection sampler provided by the present invention comprises:

[0044] The shell 1 is set as a hollow structure;

[0045] The sampling cylinder 2 is set in the housing 1 and includes a hollow cylinder 2-1 with one end set as an open opening, an air inlet 2-2 located at one end away from the open opening, and an air inlet 2-2 located at the end far from the open opening. The air outlet 2-3 on the side wall, the air inlet 2-2 and the air outlet 2-3 are all provided with a first one-way valve 5-1;

[0046] The propulsion device 3 includes a piston 3-1 arranged in the hollow cylinder 2-1 and slidingly connected with the hollow cylinder 2-1, and one end is fixed on the piston 3-1 away from the air inlet 2-2 The propelling rod 3-2 on one end face of the propelling rod 3-2, the driving device 3-3 that is located at the other end of the propelling rod 3-2, the propelling rod 3-2 is set as a worm, and the propelling device 3-...

Embodiment 2

[0068] Embodiment 2 is the same as embodiment 1 and will not be described in detail, see Figure 4 to Figure 9 , the difference is that, in order to replace the sample storage device more conveniently and conveniently, in a preferred embodiment of the present invention, the outlet end of the second one-way valve 5-2 is provided with a first pipeline 5-21, the The air detection sampler also includes a first connector 8-1 with one end fixed on the inlet end of the storage bag 4-2, and a second connector 8-1 fixed at the outlet end of the second one-way valve 5-2. The connecting piece 8-2, the second connecting piece 8-2, the first connecting piece 8-1 is engaged with the second connecting piece 8-2.

[0069] In order to avoid improving the sealing between the first and second connectors, a preferred embodiment of the present invention is that the first connector 8-1 includes a first circular ring with one end fixed at the inlet end of the storage bag 4-2. The pipe 8-11, the fla...

Embodiment 3

[0074] Embodiment 3 is the same as embodiment 1 and will not be described in detail, see Figure 10 to Figure 12 , the difference is that, in order to prevent small flying insects and sundries from falling into the pipeline of the air inlet through the air inlet, and block the air inlet of the sampling cylinder, a preferred embodiment of the present invention also includes one end connected with The first one-way valve 5-1 at the air inlet 2-2 is connected to an elbow 10-1 arranged in an inverted U shape, and an insect-proof pipe 10-2 fixed at the other end of the elbow 10-1 The insect-proof pipe 10-2 includes a through pipe 10-21 which is hollow and one end is connected to the elbow 10-1, coaxially arranged in the through pipe 10-21 and has a through hole in the middle. Separator 10-22, a plurality of bent-shaped baffles 10-23 divergently arranged on the side of said separator 10-22 close to said elbow 10-1 and arranged in a circular array, and a plurality of The connecting ...

Abstract

The invention relates to a sampler for the air detection, comprising: a housing, a sampling cylinder, a propulsion device and a sample storage unit. The housing is set to a hollow structure. The sampling cylinder comprises a hollow cylinder having an opening at one side, an air inlet disposed at the side away from the opening, and an air outlet disposed at the side wall away from the opening. Thepropulsion device comprises a piston disposed in the hollow cylinder and connected to the hollow cylinder in a sliding manner, a propulsion rod having one end fixed to the end surface of the piston, which is away from the air inlet, and a driving device provided at the other end of the propulsion rod. The propulsion rod is set as a worm. The driving device comprises a driving motor fixed in the housing through a supporting plate, a worm wheel sleeved on the output shaft of the driving motor and meshed with the propulsion rod. The sample storage unit is respectively connected to the air outletthrough a pipe. The sampler for the air detection can remotely control the sampling, so that the operators do not need to operate the sampler at the collection point for sampling, thereby reducing therisk of the operators while taking the samples.

Description

technical field [0001] The invention relates to the field of gas detection equipment, in particular to an air detection sampler. Background technique [0002] Gas samplers are widely used in atmospheric environment monitoring, sanitation and epidemic prevention, labor protection, scientific research and other units, and can also be used in conjunction with related instruments. Through the analysis of the sampled gas, we can understand the extent of the environment being polluted by harmful gases, and provide the actual situation of the pollution to the relevant authorities to take countermeasures, so as to ensure that people have a healthy living environment. [0003] Chinese patent CN108152091A discloses an air detection sampler, which includes a gas collecting pipe, a piston, an air source collecting ball and a sampling bag. An air source collecting ball is arranged on the trachea. The front end face of the air collecting pipe is a sealing face, and an air outlet pipe is...
