Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0027] See also Figure 1-4 The utility model provides a textile fabric sampling and detection device, comprising a sampling body 1, a fixed rod 5 connected to the central position of the bottom end of the sampling body 1, a rotating disk 6 connected to the outer surface of the fixed rod 5, a collecting tube 7 connected to the outer position of the bottom end of the rotating disk 6, an air intake pipe 9 connected to the central position of the top end of the collecting tube 7, a first connecting tube 10 connected to the outer end position of the air intake pipe 9, a fixed column 11 connected to the inner outer end position of the first connecting tube 10, a sealing cover 12 connected to the outer surface of the fixed column 11 and a second connecting tube 13 connected to the outer position of the bottom end of the sampling body 1, the first connecting tube 10 is located at the outer position of the upper end of the rotating disk 6, and the positions of the first connecting tube 10 and the second connecting tube 13 correspond, the sealing cover 12 seals the first connecting tube 10, so that the outside air cannot enter the collecting tube 7 through the first connecting tube 10 and the air intake pipe 9.

[0028] Further Figure 2 As shown, it is worth specifically explaining that a first handle 2 is connected to the central position of the upper end of the sampling body 1, a sampling tube 3 is connected to the outer surface of the sampling body 1, and a negative pressure pump 4 is connected to the inside of the sampling body 1. The negative pressure pump 4 is used to generate negative pressure inside the sampling body 1 and suck air from the outside into the internal position of the sampling body 1.

[0029] Further Figure 3 As shown, it is worth explaining in detail that a detection body 8 is connected to the bottom end of the collecting tube 7, and the fixing rod 5 is an inverted T-shaped structure. A through hole is provided at the central position of the rotating disk 6 relative to the fixing rod 5. The fixing rod 5 is used to support the rotating disk 6, and the rotating disk 6 can rotate on the fixing rod 5, thereby driving the lower collecting tube 7, the air intake pipe 9, and the first connecting pipe 10 to rotate.

[0030] Further Figure 3 As shown, it is worth explaining in detail that the second connecting pipe 13 is located at the upper end of the first connecting pipe 10, and the sealing cover 12 is flush with the second connecting pipe 13. Through the first connecting pipe 10 and the second connecting pipe 13, the collecting pipe 7, the air inlet pipe 9 and the interior of the sampling body 1 are connected.

[0031] Further Figure 3As shown, it is worth explaining in detail that the first connecting tube 10 and the sealing cover 12 have a hollow structure opened relative to the fixed column 11, and the diameter of the first connecting tube 10 is larger than the diameter of the intake pipe 9. The first connecting tube 10 is used to connect the intake pipe 9 and the second connecting tube 13, and the sealing cover 12 can rotate along the intake line of the fixed column 11.

[0032] This solution has the following working process: before using the sampling body 1 for sampling, the sealing cover 12 is rotated through the fixed column 11 so that the sealing cover 12 is connected to the upper end position of the first connecting tube 10 to seal the first connecting tube 10. When air sampling is required, the rotating disk 6 is rotated, and the rotating disk 6 drives the first connecting tube 10 and the collecting tube 7 to rotate. When the sealing cover 12 is rotated to contact the second connecting tube 13, the second connecting tube 13 squeezes the sealing cover 12 so that the sealing cover 12 rotates along the fixed column 11, thereby exposing the first connecting tube 10. The rotating disk 6 continues to be rotated until the second connecting tube 13 corresponds to the first connecting tube 10, and then the negative pressure pump 4 is started to suck the outside air into the sampling body 1 and collected by the collecting tube 7. At this time, the remaining collecting tubes 7 are still sealed by the sealing cover 12, and no air will enter the inside.

[0033] According to the above working process, it can be known that: multiple collecting tubes 7 are set and the upper ends are sealed using sealing covers 12, so that when the multiple collecting tubes 7 are sampling the air, the interior of the collecting tubes 7 will not be mixed with air samples from different locations, so that the samples will not be contaminated, thereby ensuring the accuracy of the detection, and when using multiple collecting tubes 7, it is only necessary to rotate the rotating disk 6, which is simple to operate and easy to use.

[0034] Further Figure 4 As shown, it is worth explaining in detail that a hollow groove is opened at the upper end of the outer side of the sampling body 1, and the movable plate 14 passes through the hollow groove and is placed at the upper end of the inner side of the sampling body 1. The first limiting plate 15 and the second limiting plate 16 are connected to both sides of the movable plate 14 respectively.

[0035] Further Figure 4 As shown, it is worth to explain in detail that a plurality of ventilation holes 17 are provided on the upper end of the movable plate 14, a placement groove 18 is provided at the central position of the upper end of the movable plate 14, and a second handle 19 is connected to the outer side of the first limiting plate 15

[0036] In summary: by setting a movable plate 14 at the upper end position inside the sampling body 1, and connecting the first limiting plate 15 and the second limiting plate 16 at the upper ends of the movable plate 14 respectively, the position of the movable plate 14 is limited by the first limiting plate 15 and the second limiting plate 16 so that it will not detach from the sampling body 1. When the sampling body 1 needs to be kept clean, the second handle 19 is used to pull the movable plate 14 outward, and then the activated carbon bag or desiccant is placed in the placement groove 18 according to the situation to clean the air in the sampling body 1 so that the sampling body 1 can be used for sampling.
