In addition, the heat sink 5 close to the collection component 4 is arranged in the gas collection and analysis device, which can dissipate heat for the collection component 4 and improve the heat dissipation efficiency of the collection component 4.

[0049] In some embodiments, the pipeline assembly 6 includes a sampling pipeline 601, an air outlet pipeline 602 and a cleaning pipeline 603, the sampling pipeline 601 is connected to the air inlet 404 of the collection component 4; the air outlet pipeline 602 is connected to the air outlet 405 of the collection component 4; the cleaning pipeline 603 is connected to the sampling pipeline 601 and / or the air outlet pipeline 602. The sampling pipeline 601 is a pipeline for transporting the sampled gas into the collection component 4. The gas with detection is passed into the collection component 4, and the collection component 4 collects and analyzes the gas transported by the sampling pipeline 601; the gas outlet pipeline 602 is used to discharge the gas collected and analyzed by the collection component 4, and discharges the gas collected by the collection component 4; the cleaning pipeline 603 is connected to at least one of the sampling pipeline 601 and the gas outlet pipeline 602, and the sampling pipeline 601 and the gas outlet pipeline 602 are both connected to the collection component 4. With this arrangement, the gas outlet pipeline 602 can clean the sampling pipeline 601, the gas outlet pipeline 602 and the collection component 4.

[0050] For example, in order to improve the cleaning efficiency of the cleaning pipeline, the cleaning pipeline is connected to the sampling pipeline 601, so the outlet of the gas outlet pipeline 602 ( Figure 2 The a port shown in FIG. 1 ), the inlet of the sampling line 601 ( Figure 2 b port shown in FIG) and the inlet of the cleaning line 603 ( Figure 2 The c port shown in the figure is arranged in the vertical direction, which can improve the convenience of arranging the outlet of the gas outlet pipeline 602, the inlet of the sampling pipeline 601 and the inlet of the cleaning pipeline 603, and improve the stability of the structure. The inlet of the sampling pipeline 601 is located between the outlet of the gas outlet pipeline 602 and the inlet of the cleaning pipeline 603, which can facilitate the arrangement of the above pipelines and make the above pipeline arrangement concise and clear.

[0051] In some embodiments, the gas collection and analysis device further comprises a multi-way valve 7, the multi-way valve 7 having a first port ( Figure 8 d port shown in FIG), and a second port ( Figure 8 e port shown in FIG), and a third port ( Figure 2 f port shown in ).

[0052] In this embodiment, an optional implementation is provided, in which a first pump 8 is provided in the sampling pipeline 601 and / or the gas outlet pipeline 602, and a second pump 9 is provided in the cleaning pipeline 603. In this way, when collecting gas, the first pump 8 located in the sampling pipeline 601 and / or the gas outlet pipeline 602 is turned on, and the second pump 9 located in the cleaning pipeline 603 is turned off, so that the gas to be collected will enter the sampling pipeline 601 through the inlet of the sampling pipeline 601, and the gas inlet direction of the gas to be collected is Figure 6The gas flows in the direction indicated by the arrow h, and then flows through the first and third ports of the multi-way valve 7 into the collection component 4, which collects and analyzes the gas. After that, the gas is discharged to the outside of the gas collection and analysis device through the gas outlet pipeline 602. The direction of the gas outflowing from the gas outlet pipeline 602 is Figure 7 and so configured, when the collected gas flows through the multi-way valve 7, it will not flow back into the second pump 9 of the cleaning pipeline 603.

[0053] When cleaning the gas collection and analysis device, the second pump 9 located in the cleaning pipeline 603 is turned on, and the first pump 8 located in the sampling pipeline 601 and / or the outlet pipeline 602 is turned on, and the cleaning gas enters the cleaning pipeline 603 through the inlet of the cleaning pipeline 603. The inlet direction of the cleaning gas is Figure 8 The cleaning gas flows in the direction indicated by the middle arrow j, and then flows through the second port of the multi-way valve 7. In the three-way valve, the cleaning gas is divided into two paths. One path flows through the first port of the multi-way valve 7 to the sampling pipeline 601 and then is discharged to the outside of the gas collection and analysis device. The other path flows through the third port of the multi-way valve 7 to the collection component 4 and then flows to the outlet pipeline 602 until it flows to the outside of the gas collection and analysis device. The outlet direction is Figure 8 In the direction indicated by the arrow k, the cleaning gas can clean the above two pipelines and the collection component 4 at the same time, thereby improving the cleaning efficiency of the gas collection and analysis device.

[0054] In this embodiment, an optional implementation is also provided, in which the multi-way valve 7 is a three-way proportional valve. The multi-way valve 7 is set as a three-way proportional valve, and the three-way proportional valve can control the opening of the three openings of the three-way proportional valve through a controller. In this way, the setting position of the first pump 8 and the second pump 9 can be flexibly adjusted. In this way, by adjusting the opening of the three-way proportional valve and cooperating with the first pump 8 and the second pump 9, the gas collection and analysis, as well as the cleaning of the sampling pipeline 601, the gas outlet pipeline 602 and the collection part 4 can be flexibly realized, thereby improving the flexibility of the above-mentioned adjustment, improving the convenience of adjustment, and improving the degree of automation of gas flow during the cleaning process.

[0055] In some embodiments, the gas collection and analysis device includes a heat sink 5 located in the accommodating cavity, and the heat sink 5 is arranged on the bottom plate 2, and the heat sink 5 can dissipate heat to the collection part 4; the heat sink 5 is arranged close to the collection part 4, and can dissipate the heat generated by the collection part 4, thereby ensuring that the collection part 4 can work normally, improving its working efficiency and extending its service life. The pipeline assembly 6 includes a sampling pipeline 601, an air outlet pipeline 602, and a cleaning pipeline 603. The shell 1 includes a front and a back, the screen 3 is arranged toward the front, and an air outlet 10 is arranged on the back, and the air outlet 10 is arranged in alignment with the heat sink 5. Specifically, the screen 3 is arranged toward the front, which can facilitate the operation of the operator; accordingly, the air outlet 10 is arranged on the back of the shell 1, so that the exported hot air does not blow to the operator located at the front, which can facilitate the heat dissipation of the heat sink 5 to the collection part 4 and other structures located in the accommodating cavity, and improve the heat dissipation efficiency. The air outlet 10 is arranged in alignment with the heat sink 5 to further improve the heat dissipation effect of the heat sink 5.

[0056] In some embodiments, a solenoid valve 11 is provided in the air outlet pipeline 602, and / or a solenoid valve 11 is provided in the air outlet pipeline 602, and / or a solenoid valve 11 is provided in the cleaning pipeline 603. Specifically, by providing a solenoid valve 11 in the air outlet pipeline 602 and / or the air outlet pipeline 602 and / or the cleaning pipeline 603, when the first pump 8 and / or the second pump 9 are in working state, at least one solenoid valve 11 located in the above pipeline is closed, and the pressure of the gas located in the part of the pipeline can be increased by pressurizing the gas by the first pump 8 and / or the second pump 9. When the above pressure reaches a certain range, the closed solenoid valve 11 is opened again, which can increase the pressure of the gas and improve the circulation speed of the gas. Moreover, by closing or opening the above solenoid valve 11, gas backflow can be avoided, and flexibility in regulating the gas flow path can be achieved.

[0057] In some embodiments, the collection component 4 includes a first shell 401, a second shell 402, a gas collection plate 403, an air inlet 404 and an air outlet 405. The first shell 401 is connected to the second shell 402 to form a cavity; the gas collection plate 403 is located in the cavity for collecting and analyzing the gas; the air inlet 404 and the air outlet 405 are both arranged on the wall of the first shell 401 or the second shell 402. In the collection component 4, by receiving the gas transported from the sampling pipeline 603, the gas is collected and analyzed, and the efficiency of collecting and analyzing the gas is improved. Moreover, the air inlet 404 and the air outlet 405 are both arranged on the wall of the first shell 401 or the second shell 402 body 1, so that the air inlet 404 and the air outlet 405 can be ensured to be located in the same area of ​​the above-mentioned cavity, and the gas can be discharged conveniently.

[0058] In some embodiments, a plurality of gas sensors 12 are provided on the gas collection board 403, and the gas sensors 12 are arranged in an array. Specifically, the plurality of gas sensors 12 are of different types, so that different types of gases can be collected and analyzed by different types of gas sensors 12, thereby improving the efficiency of gas analysis. Further, the gas sensors 12 are arranged in an array on the gas collection board 403, which can increase the contact area between the gas sensor on the gas collection board 403 and the gas entering the sampling pipeline 603, increase the sensitivity of the gas sensor 12 in receiving gas, and improve the accuracy of gas collection by the gas sensor 12.

[0059] In some embodiments, the air inlet 404 and the air outlet 405 are located on the side of the gas collection plate 403 away from the screen 3. Specifically, since the gas collection plate 403 is the main component in the collection component 4 for realizing gas collection, the gas collection plate 403 needs to be electrically connected to the screen 3, so that the screen 3 can display the gas information collected and analyzed by the gas collection component 4. Here, the air inlet 404 and the air outlet 405 are located on the side of the gas collection plate 403 away from the screen 3, so that the gas flowing from the sampling pipeline 603 to the collection component 4 will not contact with the wires and other components, thereby avoiding gas pollution and corrosion of the wires, and improving the safety of the gas collection and analysis device when in use. In addition, the above-mentioned pipeline arrangement can also make the arrangement of the pipeline assembly 6 and the collection component 4 more compact, reducing the volume of the gas collection and analysis device.
