Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a gas sampling device for air monitoring includes a collection host 1, an inhalation end 2, a connecting pipe 3 and a connecting pipe 4. The collection host 1 is fixedly provided with an inhalation end 2 at the top, and a connecting pipe 3 is fixedly provided at the side of the inhalation end 2. A connecting pipe 4 is arranged at one side of the top of the collection host 1. A closing mechanism 5 is fixedly provided inside one side of the collection host 1. The closing mechanism 5 includes a placement groove 51, an electric push rod 52, an extrusion block 53 and a clamping block 54. A placement groove 51 is provided on one side of the interior of the collection host 1. The electric push rod 52 is fixedly installed inside the placement groove 51. The extrusion block 53 is fixedly installed at the output end of the electric push rod 52. A clamping block 54 is fixedly provided on one side of the interior of the placement groove 51. The closing mechanism 5 is used to extrude the connecting pipe 4. A conveying mechanism 6 is fixedly provided on the top of the collection host 1. The conveying mechanism 6 is used to stably convey the color developer. A mixing mechanism 7 is fixedly provided on the side of the collection host 1. The mixing mechanism 7 is used to quickly position and seal the detection component.

[0030] During use, the collection host 1 is used, and the suction end 2 collects external air, and then mixes it with the collection liquid inside the device, and then transports it to the internal components of the mixing mechanism 7 through the connecting pipe 3, and the color developer is input into the mixing mechanism 7 through the use of the conveying mechanism 6. During the transportation process, the closing and opening of the connecting pipe 4 can be controlled by the use of the closing mechanism 5. By starting the electric push rod 52, the extrusion block 53 gradually approaches the clamping block 54. When the distance between the extrusion block 53 and the clamping block 54 is adjusted to a certain extent, the inner walls on both sides of the connecting pipe 4 are fitted together, and the connecting pipe 4 is closed as a whole to control the volume of the color developer input into the mixing mechanism 7. Finally, the collecting liquid and the color developer are mixed by the use of the mixing mechanism 7, making the use of the device more convenient and accurate.

[0031] By the attached Figure 4As shown, in this embodiment, an elastic wear-resistant rubber tube is installed on the outside of the connecting pipe 4 between the extrusion block 53 and the clamping block 54. When the extrusion block 53 and the clamping block 54 repeatedly squeeze the pipeline during use, the pipeline can still be used normally, and it is also convenient for subsequent separate replacement.

[0032] By the attached Figure 4 As shown, in this embodiment, the top of the extrusion block 53 is chamfered, and the extrusion block 53 will not damage the outer surface of the connecting tube 4 when extruding the connecting tube 4. When the side of the extrusion block 53 is in contact with the outer surface of the connecting tube 4 during use, it will not cause excessive damage to the outer surface of the connecting tube 4.

[0033] By the attached Figure 5 As shown, in this embodiment, the conveying mechanism 6 includes a bracket 61, an elastic clamping frame 62, a liquid storage tank 63, a conveying pipe 64 and a collecting end 65. The bracket 61 is fixedly installed on the surface of the collection host 1, the elastic clamping frame 62 is fixedly installed on the top of the bracket 61, the liquid storage tank 63 is arranged inside the elastic clamping frame 62, the conveying pipe 64 is fixedly installed at the bottom of the liquid storage tank 63, and the collecting end 65 is fixedly installed at the bottom of the conveying pipe 64. The collecting end 65 is connected to the connecting pipe 4.

[0034] During use, the color developer to be used is poured into the liquid storage tank 63, and then the liquid storage tank 63 is installed to the middle end of the elastic clamping frame 62. Thereafter, the color developer is transported through the cooperation of the delivery pipe 64 and the connecting pipe 4. During the transportation process, the collection end 65 can be used to detect the size of the color developer transported inside the pipeline, so as to facilitate accurate control of the color developer capacity.

[0035] By the attached Figure 5 As shown, in this embodiment, a scale is provided on the outer surface of the collecting end 65. When in use, after the connecting tube 4 is closed, the collecting end 65 can detect the volume of the developer existing inside itself.

[0036] By the attached Figure 6 As shown, in this embodiment, the mixing mechanism 7 includes a mounting groove 71, a storage bin 72, a test tube 73, a lifting plate 74, a spring 75, a support plate 76 and a sealing block 77. A mounting groove 71 is opened on the side of the collection host 1, the storage bin 72 is fixedly installed inside the mounting groove 71, the test tube 73 is slidably installed inside the storage bin 72, the test tube 73 is connected to the connecting pipe 3, the lifting plate 74 is symmetrically fixedly installed on both sides of the storage bin 72, the support plates 76 are symmetrically fixedly installed inside the mounting groove 71, a spring 75 is arranged between the support plate 76 and the lifting plate 74, a sealing block 77 is arranged at the top of the test tube 73, and the sealing block 77 is fixedly connected to the connecting pipe 4.

[0037] During use, by pressing the lifting plate 74, the lifting plate 74 moves downward, so that the distance between the storage bin 72 and the sealing block 77 is enlarged, which facilitates the installation of the test tube 73 into the storage bin 72, and the side of the test tube 73 is connected to the connecting tube 3, which facilitates the input of the collection liquid into the test tube 73. Afterwards, by using the spring 75, the storage bin 72 is quickly reset, and the test tube 73 will automatically fit with the sealing block 77, and the top opening of the test tube 73 is sealed, ensuring that the color developer in the connecting tube 4 can be stably transported to the inside of the test tube 73 and fully react with the collection liquid.

[0038] By the attached Figure 6 As shown, in this embodiment, a sealing rubber block is installed at the bottom end of the sealing block 77 to enhance the sealing performance when the collection liquid and the developer are mixed inside the test tube 73. During use, the use of the sealing block 77 enhances the sealing performance of the entire component, allowing the collection liquid to stably enter the interior of the test tube 73.

[0039] By the attached Figure 6 As shown, in this embodiment, a pressing block is fixedly installed on the side of the lifting plate 74. When the lifting plate 74 is pressed during use, the operation can be directly performed through the pressing block on the side, making the overall operation simpler and more convenient.
