When one of the gas pool cavities 11 is contaminated and can no longer be used, another gas pool cavity 11 can be switched for gas detection. When performing gas detection, if the detection mechanism detects that the corresponding gas pool cavity 11 is contaminated, the second driving mechanism 50 can drive the inlet and outlet gas assembly 40 to separate from the corresponding pore group 12, the first driving mechanism 30 can drive the gas containing device 10 to rotate, thereby switching the gas pool cavity 11 that meets the requirements, and the second driving mechanism 50 can then drive the inlet and outlet gas assembly 40 to dock with the pore group 12 of the gas pool cavity 11 that meets the requirements, thereby achieving the effect of automatically selecting the gas pool cavity 11 that meets the requirements to detect the gas concentration.

[0060] As an example, if the gas pool chamber 11 adjacent to the contaminated gas pool chamber 11 has not been used, the gas pool chamber 11 adjacent to the contaminated gas pool chamber 11 can be used to detect the gas concentration, and so on, when the gas pool chamber 11 needs to be replaced each time, the adjacent uncontaminated gas pool chamber 11 can be used, which is convenient for identifying the position of the uncontaminated gas pool chamber 11 in the remaining gas pool chambers 11, and when multiple gas pool chambers 11 cannot be used, the gas containing device 10 is cleaned and maintained. By providing multiple gas pool chambers 11, the number of times the gas containing device 10 is cleaned and maintained can be reduced, the maintenance cycle of the gas containing device 10 can be extended, which is conducive to reducing labor costs and maintenance costs, and can also improve the detection efficiency of gas concentration.

[0061] According to the gas detection system 1 of the embodiment of the present application, it can be used to detect gas concentration and whether the gas pool cavity 11 is contaminated. If the gas pool cavity 11 is contaminated, the gas pool cavity 11 can be replaced by rotating the gas containing device 10. When all the gas pool cavities 11 are contaminated, the gas containing device 10 is cleaned and maintained, which can achieve the effect of detecting the gas concentration and the cleanliness of the gas pool cavity 11, which is beneficial to improving the detection efficiency and improving the accuracy of the gas concentration detection results. It can reduce the number of times the gas containing device 10 is cleaned and maintained, and extend the maintenance cycle of the gas detection system 1, which is beneficial to reducing labor costs and maintenance costs.

[0062] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the detection mechanism includes a light source generator 61 and a detection receiver 62. The light source generator 61 and the detection receiver 62 are respectively located on both sides of the gas containing device 10 along the axial direction of the gas containing device 10. The light source generator 61 is used to emit light into the corresponding gas pool cavity 11, and the detection receiver 62 is used to receive the light emitted by the light source generator 61.

[0063] The detection mechanism may include a light source generator 61 and a detection receiver 62, and the light source generator 61 and the detection receiver 62 are correspondingly arranged along the third direction. The light source generator 61 and the detection receiver 62 are respectively located on both sides of the gas containing device 10 along the axial direction of the gas containing device 10 (i.e., the third direction). The light source generator 61 can emit a light beam into the corresponding gas pool cavity 11, and the detection receiver 62 can receive the light signal emitted by the light source generator 61, thereby realizing the effect that the detection mechanism detects the gas concentration in the corresponding gas pool cavity 11 and detects whether the corresponding gas pool cavity 11 is contaminated. When the corresponding gas pool cavity 11 is contaminated, the intensity of the light signal received by the detection receiver 62 becomes weak.

[0064] The light source generator 61 and the detection receiver 62 can be a variety of combinations, and the light source generator 61 and the detection receiver 62 are used together. As an example, when the light source generator 61 is an infrared light source generator 61, the detector receiver is a pyroelectric detector or a thermopile detector, and the light source generator 61 and the detection receiver 62 together constitute a non-dispersive infrared gas detection mechanism. As another example, when the light source generator 61 is an ultraviolet light source generator 61, the detection receiver 62 is a photoelectric sensor receiver, and the light source generator 61 and the detection receiver 62 together constitute a non-dispersive ultraviolet gas detection mechanism. As another example, when the light source generator 61 is a laser light source generator 61, the detection receiver 62 is a photoelectric sensor receiver, and the light source generator 61 and the detection receiver 62 together constitute a laser gas detection module.

[0065] One of the light source generator 61 and the detection receiver 62 can be located on the same side of the gas containing device 10 as the first driving mechanism 30, and the other of the light source generator 61 and the detection receiver 62 can be located on the other side of the gas containing device 10 along the third direction. The embodiment of the present application is described by taking the light source generator 61 and the first driving mechanism 30 as being located on the same side of the gas containing device 10, and the detection receiver 62 as being located on the other side of the gas containing device 10 along the third direction as an example. The light source generator 61 and the first driving mechanism 30 can be jointly provided on the second support seat 22, and the light source generator 61 can be connected to the second support plate 222 by means of snap connection, bolt connection, etc. The light source generator 61 and the corresponding gas pool cavity 11 are arranged correspondingly along the third direction.

[0066] The mounting base 20 may further include a fourth support base 24, which may be fixedly connected to the bottom plate 25, and the fourth support base 24 may be arranged along the second direction with the first support base 21, and the detection receiver 62 may be disposed on the fourth support base 24, so that the detection receiver 62 is fixedly disposed on the mounting base 20. The fourth support base 24 may include a fourth base 241 and a fourth support plate 242, and the fourth base 241 and the fourth support plate 242 may both be configured as a plate structure with a rectangular cross-section, and the fourth base 241 and the fourth support plate 242 may be welded and connected, and the fourth base 241 and the fourth support plate 242 may be integrally formed, and an angle may be formed between the fourth base 241 and the fourth support plate 242, and the angle may be a right angle or a right angle-like angle. The detection receiver 62 can be connected to the fourth support plate 242 by means of clamping, bolt connection, etc. The fourth base 241 can be formed with a fourth mounting hole 243, and there can be multiple fourth mounting holes 243. The multiple fourth mounting holes 243 can be arranged along the second direction, which is conducive to improving the connection strength between the fourth support seat 24 and the bottom plate 25. The fourth base 241 can be connected to the bottom plate 25 by bolts, and the bolts can pass through the fourth mounting holes 243 and be assembled with the bottom plate 25. As an example, the fourth mounting hole 243 can be a long strip hole, so that the effect of adjusting the relative position of the detection receiver 62 and the light source generator 61 can be achieved.

[0067] In some embodiments of the present invention, Figure 5 , Figure 6 and Figure 8 As shown, the air inlet and outlet assembly 40 may include: a fixed plate 41, a first pipeline 42 and a second pipeline 43. The fixed plate 41 is connected to a second driving mechanism 50. The first pipeline 42 and the second pipeline 43 are both fixed to the fixed plate 41. The second driving mechanism 50 is used to drive the air inlet and outlet assembly 40 to move toward or away from the gas containing device 10 so that the first pipeline 42 and the second pipeline 43 can be docked with or separated from the corresponding air hole group 12.

[0068] Along the second direction, the fixing plate 41 can be arranged corresponding to the side wall of the gas containing device 10, and the fixing plate 41 can be arranged spaced apart from the gas containing device 10. The inlet and outlet gas assembly 40 can be connected to the second drive mechanism 50 through the fixing plate 41, and the fixing plate 41 can be connected to the second drive mechanism 50 by means of clamping, bolting, etc. As an example, when the second drive mechanism 50 is configured to push the cylinder, the fixing plate 41 can be connected to the piston rod. As another example, when the second drive mechanism 50 includes a drive coil 51 and a drive rod 52, the fixing plate 41 can be connected to the drive rod 52. The first pipeline 42 and the second pipeline 43 can both extend along the arrangement direction of the fixing plate 41 and the gas containing device 10 (i.e., the second direction), and the first pipeline 42 and the second pipeline 43 can both be penetrated through the fixing plate 41, and the first pipeline 42 and the second pipeline 43 can be arranged relatively and spaced apart along the third direction. As an example, the second drive mechanism 50 can be arranged between the first pipeline 42 and the second pipeline 43.

[0069] The second driving mechanism 50 can drive the fixed plate 41 to move, and the fixed plate 41 drives the first pipeline 42 and the second pipeline 43 to move, so that the second driving mechanism 50 is used to drive the gas inlet and outlet assembly 40 to move toward or away from the gas containing device 10, so that the first pipeline 42 and the second pipeline 43 can be connected with or separated from the corresponding air hole group 12. When the second driving mechanism 50 drives the gas inlet and outlet assembly 40 to move toward the gas containing device 10, the first pipeline 42 and the second pipeline 43 are connected with the corresponding air hole group 12, and when the second driving mechanism 50 drives the gas inlet and outlet assembly 40 to move in a direction away from the gas containing device 10, the first pipeline 42 and the second pipeline 43 are separated from the corresponding air hole group 12.

[0070] In some embodiments of the present invention, Figure 7 As shown, the gas detection system 1 may include an air inlet pipeline 91 and an air outlet pipeline 92. The air inlet pipeline 91 may be connected to the first pipeline 42, and the air outlet pipeline 92 may be connected to the second pipeline 43. The detected gas may enter the gas detection system 1 through the air inlet pipeline 91, and the detected gas may enter the gas pool cavity 11 through the first pipeline 42 and the corresponding air hole group 12. The detected gas may be discharged from the gas pool cavity 11 through the corresponding air hole group 12 and the second pipeline 43, and the detected gas may be discharged from the gas detection system 1 through the air outlet pipeline 92. The air inlet pipeline 91 and the air outlet pipeline 92 may be made of corrosion-resistant materials, and the air inlet pipeline 91 and the air outlet pipeline 92 may be configured as hoses. By configuring the air inlet pipeline 91 and the air outlet pipeline 92 as hoses, the air inlet pipeline 91 and the air outlet pipeline 92 will not generate resistance to limit the movement of the air inlet and outlet assembly 40 during the movement of the air inlet and outlet assembly 40 along the second direction. As an example, both the air inlet pipe 91 and the air outlet pipe 92 may be constructed as fluororubber hoses.

[0071] The air inlet pipeline 91 may be provided with a condenser 93 and a filter 94. The condenser 93 may be provided at the entrance of the air inlet pipeline 91. The condenser 93 may be used to separate water vapor mixed in the detected gas. The water vapor may condense into liquid water in the condenser 93, thereby reducing the influence of water vapor on the gas concentration detection result. The condenser 93 may be connected to a drainage pipeline 931, and the liquid water may be discharged through the drainage pipeline 931. The drainage pipeline 931 may be provided with a drainage pump 932. The drainage pump 932 may be used to pump the liquid water in the condenser 93 so that the condensed water may be discharged from the condenser 93. As an example, the drainage pump 932 may be a peristaltic pump. The peristaltic pump has the advantage of a small suction volume, which can reduce the probability of the detected gas being discharged through the drainage pipeline 931 and reduce the loss of the detected gas. The filter 94 may be used to filter the detected gas, thereby filtering the impurities in the detected gas. The filter 94 may be provided between the condenser 93 and the inlet and outlet gas assembly 40. The outlet of the gas outlet pipeline 92 may be provided with an air pump 95, which can provide power for the flow of gas inside the gas detection system 1. The air pump 95 continues to work during the gas concentration detection process. When the gas pool chamber 11 needs to be replaced, the air pump 95 stops working.

[0072] In some embodiments of the present invention, Figure 6 As shown, the gas detection system 1 may further include: an installation shaft 70, the mounting seat 20 is provided with a bearing, the bearing and the first driving mechanism 30 are respectively located on both sides of the gas containing device 10 along the axial direction of the gas containing device 10, and the installation shaft 70 is provided on the bearing and connected to the gas containing device 10.

[0073] The gas detection system 1 may further include a mounting shaft 70 (i.e., the first transmission shaft in the above embodiment), a bearing (i.e., the first bearing in the above embodiment) may be fixedly connected to the bottom plate 25 through the first support seat 21, the bearing and the first drive mechanism 30 are respectively located on both sides of the gas containing device 10 along the third direction, the center position of the bearing may be located at the same height as the center position of the connection hole 13, and the bearing and the first drive mechanism 30 may be arranged correspondingly along the axial direction (i.e., the third direction) of the gas containing device 10. The two ends of the mounting shaft 70 may be respectively connected to the gas containing device 10 and the bearing, the mounting shaft 70 may extend into the connection hole 13 and be fixedly connected to the gas containing device 10, the mounting shaft 70 may be inserted into the inner ring of the bearing, and the mounting shaft 70 may abut against the inner wall of the inner ring of the bearing. The outer ring of the bearing may be fixedly connected to the first support plate 212, and the outer ring of the bearing may be fixedly connected to the first support plate 212 by welding, bolt connection, etc. The inner ring and the outer ring of the bearing may rotate relative to each other, so that the mounting shaft 70 may rotate relative to the first support plate 212. When the gas containing device 10 rotates, the gas containing device 10 can drive the installation shaft 70 to rotate together, and the installation shaft 70 can rotate relative to the first support plate 212, thereby achieving the effect of the gas containing device 10 rotating around the central axis of the gas containing device 10 relative to the first support seat 21.

[0074] In some embodiments of the present invention, Figure 7 As shown, the gas detection system 1 also includes: a control unit 80, which is communicatively connected with the first drive mechanism 30, the second drive mechanism 50, and the detection mechanism. The control unit 80 is configured to determine the gas information of the gas and / or the state of the corresponding gas pool cavity 11 according to the detection information of the detection mechanism, and the control unit 80 is also configured to control the operation of the first drive mechanism 30 and the second drive mechanism 50 according to the detection information of the detection mechanism.

[0075] The control unit 80 can be communicatively connected with the first driving mechanism 30, the second driving mechanism 50, and the detection mechanism. The control unit 80 can control the first driving mechanism 30 to work or not work, so that the first driving mechanism 30 can drive the gas containing device 10 to rotate. When the first driving mechanism 30 is working, the control unit 80 sends a control signal to the first driving mechanism 30. The control unit 80 can control the first driving mechanism 30 to drive the gas containing device 10 to rotate a certain angle.

[0076] The control unit 80 can control the second driving mechanism 50 to work or not work, so that the second driving mechanism 50 can drive the inlet and outlet assembly 40 to dock or separate with the first gas communication hole 121 and the second gas communication hole 122. As an example, when the second driving mechanism 50 includes a driving coil 51 and a driving shaft, the control unit 80 can send a signal to the second driving mechanism 50 to control the driving coil 51 to selectively connect with the power supply. When the control unit 80 sends a signal to the second driving mechanism 50 to connect the driving coil 51 with the power supply, the driving coil 51 generates a magnetic field after being energized, and the driving coil 51 attracts the driving rod 52, so that the inlet and outlet assembly 40 is separated from the corresponding air hole group 12. When the control unit 80 sends a signal to the second driving mechanism 50 to disconnect the driving coil 51 from the power supply, the driving coil 51 no longer attracts the driving rod 52, and the driving rod 52 moves toward the gas containing device 10, and the inlet and outlet assembly 40 docks with the corresponding air hole group 12.

[0077] The control unit 80 can receive the detection information of the detection mechanism, and the control unit 80 can determine the gas information of the gas according to the detection information of the detection mechanism, or the control unit 80 can determine the state of the corresponding gas pool cavity 11 according to the detection information of the detection mechanism, or the control unit 80 can determine the gas information of the gas and the state of the corresponding gas pool cavity 11 according to the detection information of the detection mechanism. The embodiment of the present application is described by taking the control unit 80 determining the gas information of the gas and the state of the corresponding gas pool cavity 11 according to the detection information of the detection mechanism as an example. The control unit 80 determines the concentration of the detected gas and judges whether the gas pool cavity 11 where the gas is located is contaminated by receiving the detection information of the detection mechanism.

[0078] The control unit 80 can control the light source generator 61 to emit a light beam into the gas pool cavity 11, the detection receiver 62 can receive the light signal, the detection receiver 62 can convert the received light signal into an electrical signal, the detection receiver 62 can send the electrical signal and the received light signal to the control unit 80, the control unit 80 can receive the detection information of the detection receiver 62, and the control unit 80 can determine the gas information of the gas and the state of the corresponding gas pool cavity 11 according to the detection information of the detection receiver 62. The control unit 80 can analyze and process the received electrical signal to determine the concentration of the detected gas, and the control unit 80 can also determine whether the gas pool cavity 11 where the gas is located is contaminated according to the intensity of the light signal. If the intensity of the light signal is lower than the set value, the gas pool cavity 11 is contaminated, and if the intensity of the light signal is higher than or equal to the set value, the gas pool cavity 11 is not contaminated.

[0079] The control unit 80 can control the operation of the first driving mechanism 30 and the second driving mechanism 50 according to the detection information of the detection mechanism. When the gas pool chamber 11 is contaminated and the gas pool chamber 11 needs to be replaced, the control unit 80 first controls the vacuum pump 95 to stop working, and the control unit 80 controls the second driving mechanism 50 to work. The second driving mechanism 50 drives the gas inlet and outlet assembly 40 to move in the direction away from the gas containing device 10, and the first pipeline 42 and the second pipeline 43 are separated from the corresponding air hole group 12. The control unit 80 controls the first driving mechanism 30 to work, and the first driving mechanism 30 drives the gas containing device 10 to rotate a certain angle, so that the gas pool chamber 11 that meets the requirements is set corresponding to the detection mechanism, thereby achieving the effect of replacing the gas pool chamber 11.

[0080] The control unit 80 can also be in communication connection with the condenser 93 and the air pump 95. The control unit 80 can control the temperature of the condenser 93 so that the water vapor can condense into liquid water in the condenser 93. The control unit 80 can control the air pump 95 to work or stop working, thereby achieving the effect of controlling the gas flow in the gas detection system 1.

[0081] In the embodiment of the present application, before the detected gas enters the gas detection system 1, the control unit 80 controls the second driving mechanism 50 to drive the inlet and outlet components 40 to dock with the pore group 12 of the gas pool chamber 11, the first pipeline 42 and the second pipeline 43 are docked with the corresponding pore group 12, and the gas pool chamber 11 is connected with the inlet pipeline 91 and the outlet pipeline 92. The control unit 80 controls the air pump 95 to work, the detected gas enters the gas detection system 1 through the inlet pipeline 91, the detected gas enters the condenser 93, the water vapor in the detected gas condenses into liquid water in the condenser 93, and the liquid water can be discharged from the gas detection system 1 through the drain pipeline 931. The detected gas is filtered by the filter 94 and enters the gas pool chamber 11 through the first pipeline 42 and the corresponding pore group 12, and the gas is detected in the gas pool chamber 11. The control unit 80 controls the light source generator 61 to emit a light beam into the gas pool chamber 11, and the detection receiver 62 receives the light signal. The detection receiver 62 can convert the received light signal into an electrical signal, and the detection receiver 62 sends the electrical signal and the received light signal to the control unit 80. The control unit 80 can analyze and process the received electrical signal to determine the concentration of the detected gas. The control unit 80 can also determine whether the gas pool chamber 11 where the gas is located is contaminated based on the intensity of the light signal. If the gas pool chamber 11 is not contaminated, the gas detection system 1 continues to detect the gas concentration, and the detected gas can be discharged from the gas pool chamber 11 through the second gas connecting hole 122, and the detected gas enters the exhaust pipeline through the second pipeline 43, and the detected gas is discharged from the gas detection system 1.

[0082] If the gas pool cavity 11 is contaminated, the control unit 80 controls the air pump 95 to stop working, the gas no longer flows in the gas detection system 1, and the control unit 80 controls the second driving mechanism 50 to drive the inlet and outlet gas assembly 40 to separate from the corresponding pore group 12. The control unit 80 controls the first driving mechanism 30 to drive the gas containing device 10 to rotate, and the control unit 80 controls the first driving mechanism 30 to drive the gas containing device 10 to rotate a certain angle, so that the uncontaminated gas pool cavity 11 rotates to between the light source generator 61 and the detection receiver 62. The control unit 80 controls the second driving mechanism 50 to drive the inlet and outlet gas assembly 40 to dock with the corresponding pore group 12, and the first pipeline 42 and the second pipeline 43 to dock with the corresponding pore group 12, so that the detected gas can enter the gas pool cavity 11 that meets the requirements, and the new gas pool cavity 11 can be used to continue to detect gas concentration.

[0083] By setting up the control unit 80 to communicate with the first driving mechanism 30, the second driving mechanism 50, the detection mechanism, the condenser 93, and the vacuum pump 95, the gas detection system 1 can automatically detect the gas concentration and the cleanliness of the gas pool cavity 11, which is beneficial to improving the working efficiency of the gas detection system 1. The gas detection system 1 has a simple structure and low cost.

[0084] In some embodiments of the present application, Figure 1 As shown, along the axial direction of the gas containing device 10, the two cavity end walls of the gas pool cavity 11 are constructed as light-transmitting walls.

[0085] The gas pool cavity 11 can extend along the axial direction (i.e., the third direction) of the gas containing device 10, and each gas pool cavity 11 is formed with two cavity end walls arranged opposite to each other along the axial direction of the gas containing device 10, and the two cavity end walls close the gas pool cavity 11. Both cavity end walls can be constructed as light-transmitting walls, so that the light source generator 61 can inject a light beam into the gas pool cavity 11 through the light-transmitting walls, and the light beam can be emitted from the gas pool cavity 11 through the light-transmitting walls, and the detection receiver 62 can receive the light signal emitted by the light source generator 61. As an example, the two cavity end walls can be plane glass, so that the cavity end walls can be constructed as light-transmitting walls, and the light beam can enter the gas pool cavity 11 through the plane glass, and the light in the gas pool cavity 11 can also be emitted through the plane glass.

[0086] In some embodiments of the present application, Figure 1-Figure 4 As shown, the plurality of gas hole groups 12 are sequentially arranged along the circumference of the gas containing device 10 , and the plurality of gas hole groups 12 are connected to the plurality of gas pool cavities 11 in a one-to-one correspondence.

[0087] There may be multiple groups of pore groups 12, which may be arranged in sequence along the circumference of the gas containing device 10. There may be multiple gas pool cavities 11, which may be connected to each other one by one, and each gas pool cavity 11 may have a corresponding pore group 12 connected thereto. Each pore group 12 may be arranged on the side wall of the corresponding gas pool cavity 11, and the pore group 12 may penetrate the side wall of the corresponding gas pool cavity 11 along the thickness direction of the side wall of the corresponding gas pool cavity 11. The inlet and outlet gas assembly 40 may be docked with the pore group 12, so that the first pipeline 42 and the second pipeline 43 are connected to the corresponding gas pool cavity 11, thereby achieving the effect of detecting the detected gas in the corresponding gas pool cavity 11.

[0088] In some embodiments of the present application, Figure 1 As shown, each gas hole group 12 includes a first gas communicating hole 121 and a second gas communicating hole 122 , and the first gas communicating hole 121 and the second gas communicating hole 122 in each gas hole group 12 are arranged opposite to each other along the axial direction of the gas containing device 10 .

[0089] Each group of gas holes 12 may include a first gas communication hole 121 and a second gas communication hole 122, and the first pipeline 42 and the second pipeline 43 are respectively arranged corresponding to the first gas communication hole 121 and the second gas communication hole 122. One of the first pipeline 42 and the second pipeline 43 may be connected to the first gas communication hole 121, and the other of the first pipeline 42 and the second pipeline 43 may be connected to the second gas communication hole 122. The embodiment of the present application is described by taking the first pipeline 42 connected to the first gas communication hole 121 and the second pipeline 43 connected to the second gas communication hole 122 as an example. The detected gas enters the gas pool cavity 11 through the first gas communication hole 121, and the detected gas is discharged from the gas pool cavity 11 through the second gas communication hole 122, thereby realizing the flow of gas in the gas pool cavity 11.

[0090] When the gas containing device 10 is used to detect gas concentration, the pore group 12 can be connected to the gas inlet and outlet assembly 40. When the gas pool cavity 11 is contaminated and the next gas pool cavity 11 needs to be replaced, the gas inlet and outlet assembly 40 is separated from the pore group 12 of the contaminated gas pool cavity 11, and the gas inlet and outlet assembly 40 is connected to the pore group 12 of the next gas pool cavity 11. The first gas connecting holes 121 and the second gas connecting holes 122 in each group of pore groups 12 are arranged opposite to each other along the axial direction of the gas containing device 10, which can facilitate the connection between the pore group 12 and the gas inlet and outlet assembly 40, and is beneficial to improving the assembly efficiency of the gas containing device 10 and the gas inlet and outlet assembly 40.

[0091] In some embodiments of the present application, Figure 1 As shown, the first gas communication holes 121 and the second gas communication holes 122 in any two adjacent gas hole groups 12 are arranged opposite to each other along the circumferential direction of the gas containing device 10 .

[0092] The first gas connecting holes 121 and the second gas connecting holes 122 in any two adjacent groups of air hole groups 12 are arranged opposite to each other along the circumferential direction of the gas containing device 10, that is, the first gas connecting holes 121 of multiple groups of air hole groups 12 are arranged in sequence along the circumference of the gas containing device 10, and the second gas connecting holes 122 of multiple groups of air hole groups 12 are arranged in sequence along the circumference of the gas containing device 10, so that the spacing distances between the first gas connecting holes 121 and the second gas connecting holes 122 in the multiple groups of air hole groups 12 are the same, and the first gas connecting holes 121 and the second gas connecting holes 122 in each group of air hole groups 12 are arranged opposite to each other along the axial direction of the gas containing device 10, and the arrangement positions of the first gas connecting holes 121 and the second gas connecting holes 122 of multiple air hole groups 12 along the circumferential direction of the gas containing device 10 are the same, which can further improve the assembly efficiency of the gas containing device 10 and the gas inlet and outlet assembly 40. Furthermore, the arrangement positions of the plurality of gas hole groups 12 are the same, which facilitates the processing of the gas hole groups 12 and helps to improve the production efficiency of the gas containing device 10 .

[0093] In some embodiments of the present application, the aperture size of the first gas communication hole 121 is the same as the aperture size of the second gas communication hole 122 .

[0094] The detected gas can enter the gas pool chamber 11 through one of the first gas connecting hole 121 and the second gas connecting hole 122, and can be discharged from the gas pool chamber 11 through the other of the first gas connecting hole 121 and the second gas connecting hole 122. By setting the aperture size of the first gas connecting hole 121 and the aperture size of the second gas connecting hole 122 to be the same, the first gas connecting hole 121 and the second gas connecting hole 122 are configured as holes of the same structure, and the detected gas can enter the gas pool chamber 11 through any one of the first gas connecting hole 121 and the second gas connecting hole 122, and can be discharged from the gas pool chamber 11 through any one of the first gas connecting hole 121 and the second gas connecting hole 122. When installing the gas containing device 10, there is no need to limit the placement direction of the gas containing device 10. The gas containing device 10 can be placed toward the first driving mechanism 30 on any side along the axial direction of the gas containing device 10, and the function of the gas hole group 12 can be realized. Furthermore, the first gas connecting hole 121 and the second gas connecting hole 122 having the same aperture size can make the detected gas enter the gas pool cavity 11 and be discharged from the gas pool cavity 11 at the same rate, so that the gas flow rates entering the gas pool cavity 11 and being discharged from the gas pool cavity 11 at the same time are the same, which is beneficial to maintaining the pressure balance in the gas pool cavity 11 and ensuring the stability of the gas when being detected in the gas pool cavity 11.

[0095] In some embodiments of the present application, Figure 1 and Figure 5As shown, the central axes of the plurality of gas pool cavities 11 are located on the same circumference, and the plurality of gas pool cavities 11 are evenly arranged around the central axis of the gas containing device 10 along the circumference of the gas containing device 10 .

[0096] The central axes of the multiple gas pool cavities 11 are located on the same circumference, and the distances between the central positions of the multiple gas pool cavities 11 and the central positions of the gas containing device 10 are all equal. The multiple gas pool cavities 11 are evenly arranged along the circumference of the gas containing device 10, so that the center of gravity of the gas containing device 10 can be located on the central axis of the gas containing device 10, which is beneficial to improving the stability of the gas containing device 10. Moreover, the evenly arranged gas pool cavities 11 are convenient for production and processing, which is beneficial to improving the production efficiency of the gas containing device 10. When the gas containing device 10 needs to be rotated to replace the gas pool cavity 11, the gas containing device 10 rotates around the central axis, which is beneficial to improving the stability of the rotation of the gas containing device 10, and the gas pool cavity 11 can be switched each time the gas containing device 10 rotates the same angle.

[0097] As an example, multiple groups of pore groups 12 can be evenly arranged in sequence along the circumference of the gas containing device 10, and multiple gas pool cavities 11 can be evenly arranged along the circumference of the gas containing device 10. Multiple groups of pore groups 12 and multiple gas pool cavities 11 can be arranged one by one along the radial direction of the gas containing device 10. Along the circumference of the gas containing device 10, the interval between any two adjacent gas pool cavities 11 is the same, and the interval between any two adjacent groups of pore groups 12 is the same. When the gas pool cavity 11 is contaminated and needs to be replaced, the gas containing device 10 can switch the pore groups 12 and the gas pool cavity 11 by rotating the same angle each time. For example, when the gas containing device 10 is provided with eight groups of pore groups 12 along the circumference of the gas containing device 10, the gas containing device 10 only needs to rotate 45° each time.

[0098] In some embodiments of the present application, Figure 1-Figure 4 As shown, a connection hole 13 is formed at the center of the gas containing device 10 , and the connection hole 13 is connected to the first driving mechanism 30 .

[0099] The connection hole 13 can penetrate the gas containing device 10 along the axial direction of the gas containing device 10, and the gas containing device 10 can be connected to the first driving mechanism 30 through the connection hole 13. The gas containing device 10 can also be connected to the mounting shaft 70 through the connection hole 13, so as to achieve the effect of the gas containing device 10 rotating around the central axis of the gas containing device 10. The central axis of the connection hole 13 can be colinear with the central axis of the gas containing device 10, and the gas containing device 10 can rotate around the central axis of the connection hole 13, which is conducive to ensuring the stability and balance of the gas containing device 10.

[0100] In some embodiments of the present application, the side wall of the air pool cavity 11 is configured as a reflective wall.

[0101] The inner wall of the gas pool cavity 11 can be formed of high-polished aluminum or a gold-plated film. The inner wall of the gas pool cavity 11 is configured as a reflective wall. The light beam emitted by the light source generator 61 can enter the gas pool cavity 11 through one cavity end wall of the gas pool cavity 11. The light beam entering the gas pool cavity can be reflected by the reflective wall and transmitted to the other cavity end wall of the gas pool cavity 11. The light beam can be emitted from the gas pool cavity 11 through the other cavity end wall of the gas pool cavity 11, thereby achieving the effect of using the light beam to detect the gas concentration and judge the cleanliness of the gas pool cavity 11. When the light beam is emitted into the gas pool cavity 11, the reflective wall can make the light beam reflect in the gas pool cavity 11, increasing the chance of the light beam contacting the gas, which helps to improve the accuracy of gas concentration detection.

Each air pool hole 141 can penetrate the device body 14 along the axial direction of the device body 14, and the radial dimensions of each air pool hole 141 can be the same. Both ends of each gas pool hole 141 may be formed with mounting grooves, the mounting grooves extending along the circumference of the gas pool hole 141, the radial dimension of the mounting grooves being larger than the radial dimension of the gas pool hole 141, so as to form a limiting step surface in the gas pool hole 141, the window piece 15 may be installed in the mounting groove and abut against the limiting step surface for limiting position, the window piece 15 may be connected to the device body 14 by means of snap connection, bonding, etc., the window piece 15 may close the gas pool hole 141, so as to construct the gas pool cavity 11, and multiple gas pool holes 141 may form multiple gas pool cavities 11.
