Description

Technical Field

[0001] The present application relates to the technical field of soup identification, and in particular to a detection method and device for rapid soup identification. Background Art

[0002] Ordinary people believe that "medicine is not as good as food, and food is not as good as soup", especially the Hubei specialty lotus root soup. The lotus root is tender, crisp and sweet, rich in trace elements and very nutritious. Drinking lotus root soup regularly can provide nutrition to the human body and enhance immunity.

[0003] At present, the nutritional characteristics, safety and volatile flavor components of soup are the three main factors that determine the quality of soup. Therefore, lotus root soup needs to be tested, and gas chromatography-ion mobility mass spectrometry (GC-IMS) is generally used for testing. Gas chromatography-ion mobility mass spectrometry (GC-IMS) technology is an emerging and relatively advanced technology for rapid detection of volatile organic compounds in the world. It can simultaneously obtain the composition of flavor substances and sample quality discrimination information. It has the advantages of high sensitivity, strong resolution, high efficiency and speed, no need for complex sample pretreatment, low sample analysis temperature, etc., and can more truly reflect the flavor status of the sample.

[0004] In the prior art, a patent document with publication number CN109781918A discloses a gas phase ion mobility spectrometry identification method for rice wine produced by different enterprises, comprising the following steps: 1 mL of each rice wine sample is taken and placed in a 20 mL headspace injection bottle, and allowed to stand at room temperature for 10-30 minutes to allow the volatile gas of the rice wine to diffuse into the top space of the injection bottle, thereby obtaining the headspace gas, and then the injection bottle is connected to a gas chromatography-ion mobility mass spectrometer for detection.

[0005] Rice wine is highly volatile, so its odor can evaporate to the top space of the sampling bottle at room temperature. At the same time, when testing rice wine, it is only necessary to test the parameters of the rice wine at room temperature. Lotus root soup is made by boiling, so some components of the lotus root soup can generally be decomposed only when it is boiled. Only at this time can the detection of the lotus root soup be better and more accurate. However, the temperature is relatively high at this time, so burns are likely to occur during sampling. In addition, after sampling, staying away from fire sources will cause the temperature of the lotus root soup to drop rapidly, thereby reducing the detection effect and efficiency. Summary of the invention

[0006] In order to improve the detection effect and efficiency, the present application provides a detection method and device for quickly identifying soups.

[0007] In the first aspect, the present application provides a detection device for quickly identifying soups, which adopts the following technical solution:

[0008] A detection device for quickly identifying soups, comprising a collecting mechanism connected to an exhaust pipe used when boiling lotus root soup, the collecting mechanism comprising:

[0009] A collecting pipe, wherein the two ends of the collecting pipe are respectively a first end and a second end, both of which are connected to the exhaust pipe so that the gas in the exhaust pipe passes through the first end, the collecting pipe and the second end in sequence and then enters the exhaust pipe;

[0010] A connecting tube, which is disposed on the collecting tube and is located between the first end and the second end and is used for detachably connecting with the injection bottle;

[0011] A control component, the control component is used to control the second end to be connected or closed to the exhaust pipe and to control the connection pipe to be connected or closed to the collection pipe;

[0012] A heat preservation component is used to keep the injection bottle warm.

[0013] By adopting the above technical solution, when the lotus root soup is boiled, the exhaust pipe is started to exhaust air, so that the volatilized gas of the lotus root soup is discharged through the exhaust pipe, and the control component controls the second end to be connected with the exhaust pipe. Due to the fluidity of the gas, a part of the volatilized gas of the lotus root soup also enters the collecting pipe through the first end, and then enters the exhaust pipe again through the collecting pipe and the second end, so that the collecting pipe forms a branch of gas flow, and the gas flow will preheat the collecting pipe at this time.

[0014] As the temperature of the volatilized gas becomes higher and higher, the control component controls the connecting tube to be connected with the collecting tube, so that part of the gas in the collecting tube enters the injection bottle through the collecting tube. The hot gas entering the injection bottle also pushes the cold gas in the injection bottle to enter the exhaust pipe through the connecting tube, the collecting tube and the second end in turn. As the gas flows, the gas with higher temperature enters the injection bottle and the cold gas in the injection bottle is discharged.

[0015] When the lotus root soup boils, the temperature of the volatile gas tends to be stable. At this time, the gas entering the sampling bottle is the gas required for detection. As the gas increases after boiling, the gas concentration in the sampling bottle reaches the detection requirement. The control component controls the connecting tube to close, and then the sampling bottle can be removed, while the insulation component continues to insulate the sampling bottle. Finally, the sampling bottle is connected to the gas chromatography-ion mobility mass spectrometry for detection. Therefore, the probability of danger caused by manual sampling is reduced, and the adverse effects of gas concentration and temperature on detection are reduced, thereby improving the detection effect and efficiency.

[0016] Alternatively, the control component can also control the second end and the exhaust pipe to be closed, so that all the gas entering the collection tube enters the injection bottle, so that the required concentration of gas can be collected in the injection bottle more quickly. After this state is maintained for a period of time, the gas concentration in the injection bottle reaches the required detection requirement, thereby speeding up the efficiency of collecting gas in the injection bottle.

[0017] At the same time, compared with directly connecting the connecting tube to the exhaust pipe, the gas in the collecting tube exerts a smaller pressure on the gas output by the connecting tube, that is, the resistance to the output of the cold gas in the injection bottle is smaller, making it easier to discharge the cold gas in the injection bottle, thereby making the gas temperature and concentration in the injection bottle closer to the ideal state for detection, thereby further improving the detection effect.

[0018] Optionally, the control component includes:

[0019] A first control valve and a second control valve, wherein the first control valve and the second control valve are respectively arranged on the second end and the connecting pipe and are used to control opening and closing;

[0020] A humidity sensor and a temperature sensor are disposed at the second end portion and are used to detect the humidity and temperature of the gas passing through the second end portion and are electrically connected to the first control valve and the second control valve.

[0021] By adopting the above technical solution, the humidity sensor and the temperature sensor are used to detect the temperature and humidity of the gas passing through the second end. When the lotus root soup is boiled, the gas temperature and humidity are initially low. At this time, the first control valve is opened, and the gas can pass through the collecting tube to preheat the collecting tube. As the gas and temperature increase, the second control valve opens, so that the volatilized gas can enter the connecting tube and the injection bottle, thereby pushing the cold gas in the injection bottle to overflow and allowing the hot gas to enter.

[0022] When the lotus root soup boils, the temperature and humidity of the gas tend to be stable, so the humidity sensor and temperature sensor detect that the temperature and humidity of the gas tend to a stable value, then the timing can start, after a period of time, the gas in the sampling bottle has reached the required concentration, so the humidity sensor and temperature sensor control the second control valve to close, and then the sampling bottle can be removed for testing.

[0023] Furthermore, it can be designed that when the humidity sensor and the temperature sensor detect that the temperature and humidity of the gas tend to a stable value, the humidity sensor and the temperature sensor control the first control valve to close, and all the gas entering the collection tube enters the injection bottle, at which time the timing can be started. Therefore, after a period of time, the gas concentration in the injection bottle reaches the required requirement for detection, at which time the second control valve is controlled to close, and then the injection bottle can be removed for detection, thereby improving the detection effect and efficiency.

[0024] Optionally, the first end portion and the second end portion are spaced apart along the axis of the exhaust pipe, and the first end portion and the second end portion are detachably arranged on the exhaust pipe.

[0025] By adopting the above technical solution, the gas in the collecting tube moves from the first end to the second end, and the first end and the second end are spaced apart along the axis of the exhaust tube, so that the resistance of the gas moving in the collecting tube is smaller, thereby making the gas flow smoother, that is, the sampling bottle collects the gas faster, thereby improving the detection efficiency.

[0026] At the same time, the first end and the second end can be detached, so it is convenient to replace and install the humidity sensor and the temperature sensor, further improving the stability of control, thereby improving the detection effect and efficiency.

[0027] Optionally, the thermal insulation component includes:

[0028] A heat-insulating cover, which is arranged at the mouth of the sample injection bottle and wraps the sample injection bottle body therein for buffering protection and heat insulation, and an installation space is formed between the inner side wall of the heat-insulating cover and the sample injection bottle;

[0029] The heat-insulating component is arranged on the installation space and abuts against the injection bottle and is filled with a liquid that can absorb and release heat. The heat-insulating component absorbs heat when the gas enters the injection bottle and heats and insulates the gas in the injection bottle after the injection bottle is removed from the connecting pipe.

[0030] By adopting the above technical solution, the thermal insulation cover can insulate and protect. Therefore, when the staff takes the sampling bottle, the thermal insulation cover can reduce the probability of burns caused by increased temperature. It can also protect when the sampling bottle falls, thereby improving the convenience of detection and improving the detection efficiency.

[0031] When the gas enters the injection bottle, the gas first preheats the injection bottle. As the gas temperature rises, the gas heats the liquid in the insulation component. When the injection bottle is removed, the liquid in the insulation component can still heat and keep the gas in the injection bottle warm. The insulation cover prevents the heat in the insulation component from overflowing, thereby improving the insulation effect of the gas and making the gas temperature closer to the ideal temperature required for detection, thereby improving the detection effect and efficiency.

[0032] Optionally, the thermal insulation component is snap-fitted to the installation space, a replacement opening for taking out the thermal insulation component for replacement is provided on the thermal insulation cover, and a replacement plate for blocking the replacement opening is detachably provided on the thermal insulation cover.

[0033] By adopting the above technical solution, the insulation component is replaced after the replacement plate is opened, thereby improving the heating and heat preservation effect of the insulation component on the gas and improving the detection effect.

[0034] Optionally, the collecting pipe includes a vertical section in a vertical state, an inclined section one located at the bottom of the vertical section, and an inclined section two located at the top of the vertical section. The connecting pipe is in a vertical state and connected to the top of the vertical section. The bottom of the inclined section one is a first end and is inclined downward, and the top of the inclined section two is a second end and is inclined upward.

[0035] By adopting the above technical scheme, the gas with higher temperature rises and the gas with lower temperature falls. Therefore, when the gas in the exhaust duct moves vertically upward, the high-temperature gas is more likely to pass through the inclined section one, the vertical section and the inclined section two in sequence, so that more gas can enter the collection tube. At the same time, the connecting tube is in a vertical state and is located at the top of the vertical section, so that the gas in the vertical section can easily enter the connecting tube and the sampling bottle, and the cold gas in the sampling bottle can also easily move downward and enter the inclined section two for discharge. Finally, the discharge speed of the cold gas in the sampling bottle and the entry speed of the high-temperature gas are accelerated, thereby further improving the detection effect and efficiency.

[0036] Optionally, the injection bottle is provided with a mounting tube detachably connected to the connecting tube, and the mounting tube is provided with a sealing and heat-insulating mechanism for sealing and heat-insulating the gas in the injection bottle.

[0037] By adopting the above technical solution, the sampling bottle is detachably connected to the connecting tube through the mounting tube. When the sampling bottle needs to be removed, the sealing and insulation mechanism seals and insulates the mounting tube, making it difficult for the gas and heat in the sampling bottle to overflow, thereby further improving the insulation effect of the gas in the sampling bottle, while also reducing the probability of a decrease in the gas concentration in the sampling bottle, thereby improving the detection effect and efficiency.

[0038] After the installation tube is connected to the vertical section, the heat insulation mechanism is sealed and the installation tube is opened, so that the sample injection bottle is connected to the installation tube and the connecting tube, thereby improving the detection effect and efficiency while realizing the sample injection bottle.

[0039] Optionally, two mounting holes are provided on the mounting tube at intervals, and each mounting hole is provided with a blocking and heat-insulating mechanism, and the blocking and heat-insulating mechanism comprises:

[0040] A blocking plate, which is rotatably arranged on the mounting hole through a rotating shaft and has a heat-insulating layer arranged on the side wall close to the injection bottle, and two blocking plates cooperate to block or open the mounting tube;

[0041] A torque piece is arranged on the mounting tube and connected to the blocking plate and pushes the blocking plate to rotate to open the mounting tube; a positioning component is also arranged on the mounting tube to position the blocking plate when blocking the mounting tube.

[0042] By adopting the above technical solution, when it is necessary to seal the installation pipe, the two sealing plates are pushed close to each other and then abutted against each other, and then the positioning component positions the two sealing plates, so that the sealing plates seal the installation pipe, and at the same time the insulation layer is used to block the heat in the installation pipe. When it is necessary to connect, the positioning component unlocks the two sealing plates, and the two sealing plates drive the two sealing plates to rotate under the action of the torque member, so that the installation pipe is opened, thereby realizing the sealing, insulation or closure of the installation pipe, and when opening the installation pipe, the area of ​​gas passing through the installation pipe can be maximized, which speeds up the speed of gas passing through the installation pipe, thereby further improving the detection efficiency.

[0043] Optionally, the positioning component includes:

[0044] A positioning block, which is slidably disposed on the mounting tube and plugged and mounted on an end of the blocking plate away from the rotating shaft for positioning;

[0045] The positioning piece is arranged on the mounting tube and is pressed against the positioning block for positioning under the action of elastic force.

[0046] By adopting the above technical solution, the positioning block is inserted and installed on the blocking plate under the action of the positioning member for positioning. When unlocking is required, the positioning block is moved away from the blocking plate, and the blocking plate rotates under the action of the torque member, thereby locking and unlocking the blocking plate.

[0047] In the second aspect, the present application provides a method for identifying soups, which adopts the following technical solution:

[0048] A method for identifying soups comprises the following steps:

[0049] Preheating the collecting tube: connecting the sample injection bottle to the connecting tube, when the lotus root soup is made, the exhaust pipe is started to exhaust air, and the first control valve is opened, so that the gas volatilized from the lotus root soup passes through the collecting tube to preheat the collecting tube;

[0050] Collecting gas: When the second control valve is opened, the gas volatilized from the lotus root soup enters the injection bottle and pushes the cold air in the injection bottle out. At the same time, the gas can also heat the liquid in the insulation component. When the lotus root soup boils, the required detection gas is collected in the injection bottle. As the gas increases, the gas reaches the required concentration.

[0051] Detection: After the second control valve is closed and the sampling bottle is removed, the liquid in the insulation component heats and insulates the gas in the sampling bottle, the sampling bottle is connected to the gas chromatography-ion mobility mass spectrometry, and the gas chromatography-ion mobility mass spectrometry is started for detection, and the process is repeated to achieve detection of multiple lotus root soups.

[0052] By adopting the above technical solution, the sampling bottle is connected to the connecting pipe. When the lotus root soup is made, the exhaust pipe is started to exhaust air, and the first control valve is opened, so that the volatile gas of the lotus root soup is preheated through the collecting tube; the second control valve is opened, and the volatile gas of the lotus root soup enters the sampling bottle and pushes the cold gas in the sampling bottle to be discharged. At the same time, the gas can also heat the liquid in the insulation component.

[0053] When the lotus root soup boils, gas of the required concentration is collected in the sampling bottle; the second control valve is closed, and after the sampling bottle is removed, the liquid in the insulation component heats and insulates the gas in the sampling bottle, the sampling bottle is connected to the gas chromatography-ion mobility mass spectrometry, and the gas chromatography-ion mobility mass spectrometry is started for detection, thereby reducing the probability of danger caused by manual sampling, and also reducing the adverse effects of gas concentration and temperature changes on detection, thereby improving the detection effect and efficiency.

[0054] In summary, the present application includes at least one of the following beneficial technical effects:

[0055] When the lotus root soup is boiled, the exhaust pipe is started to exhaust air, so that a part of the gas volatilized by the lotus root soup passes through the collecting pipe and preheats the collecting pipe. As the temperature of the volatilized gas becomes higher and higher, the control component controls the connecting pipe to be connected with the collecting pipe, so that the gas with higher temperature enters the sampling bottle and the cold gas in the sampling bottle is discharged. When the lotus root soup boils, the gas concentration in the sampling bottle reaches the requirement for detection. The control component controls the connecting pipe to be closed, and then the sampling bottle can be removed for detection, thereby reducing the probability of danger caused by manual sampling, and also reducing the adverse effects of gas concentration and temperature on detection, thereby improving the detection effect and efficiency.

DETAILED DESCRIPTION

[0062] The present application is further described in detail below with reference to the accompanying drawings 1-5.

[0063] The embodiment of the present application discloses a detection device for quickly identifying soups.

[0064] Reference Figure 1 A detection device for quickly identifying soups includes a collecting mechanism 2 connected to an exhaust pipe 11 used when boiling lotus root soup. The exhaust pipe 11 is used for exhaust operation when boiling lotus root soup. The collecting mechanism 2 is used to collect the volatilized gas after the lotus root soup boils into an injection bottle 13, and the collecting mechanism 2 keeps the gas collected in the injection bottle 13 warm. Finally, the injection bottle 13 is connected to a gas chromatography-ion mobility mass spectrometer and the gas in the injection bottle 13 is detected, so as to detect the quality of the lotus root soup. At the same time, the number of collecting mechanisms 2 is designed according to needs, so as to realize the detection of lotus root soup of different types and batches.

[0065] Reference Figure 1 and Figure 2 An exhaust fan is arranged in the exhaust pipe 11 to make the air flow, and a vertical pipe 12 in a vertical state is formed on the exhaust pipe 11. The collecting mechanism 2 is connected to the vertical pipe 12, and the collecting mechanism 2 includes a collecting pipe 21, a connecting pipe 3, and a control component 4. The collecting pipe 21 includes an integrally arranged vertical section 22, an inclined section 1 23, and an inclined section 24. The vertical section 22 is in a vertical state and its axis is parallel to the axis of the vertical pipe 12. The vertical section 22 is located on one side of the vertical pipe 12, and the inner diameter of the vertical section 22 is smaller than the inner diameter of the vertical pipe 12, and the outer diameter of the vertical section 22 is smaller than the outer diameter of the vertical pipe 12.

[0066] The top end of the inclined section 1 23 is located on the bottom of the vertical section 22, and the bottom end of the inclined section 1 23 is inclined downward and arranged close to the vertical tube 12; the bottom end of the inclined section 2 24 is located on the top of the vertical section 22, and the top end of the inclined section 24 is inclined upward and arranged close to the vertical tube 12, and at the same time, the bottom end of the inclined section 1 23 is the first end 25 and the top end of the inclined section 2 24 is the second end 26.

[0067] The first end 25 and the second end 26 are fixedly connected to the vertical pipe 12 through the same structure, and the vertical pipe 12 is connected with the first end 25 and the second end 26; an arc plate is fixedly installed at the first end 25, and the arc plate is tightly attached to the outer wall of the vertical pipe 12 and fixedly connected to the outer wall of the vertical pipe 12 by screws, and connecting holes are opened on the vertical pipe 12 and at the first end 25 and the second end 26. The connecting holes are used to connect the first end 25 and the second end 26 with the vertical pipe 12. When the exhaust pipe 11 is started to exhaust, the gas in the vertical pipe 12 moves vertically upward, and at the same time, a part of the gas in the vertical pipe 12 enters the vertical pipe 12 through the first end 25, the collecting pipe 21 and the second end 26 in sequence.

[0068] Reference Figure 1 and Figure 2 The connecting tube 3 is fixedly installed on the top of the vertical section 22, and the axis of the connecting tube 3 coincides with the axis of the vertical section 22. At the same time, the outer diameter and inner diameter of the connecting tube 3 are the same as the outer diameter and inner diameter of the vertical section 22. The top of the connecting tube 3 is detachably connected to the mouth of the injection bottle 13; the control component 4 is used to control the second end 26 to be connected or closed to the vertical tube 12 and to control the connecting tube 3 to be connected or closed to the vertical section 22.

[0069] When the lotus root soup is boiled, the exhaust pipe 11 is started to exhaust air, so that part of the gas volatilized from the lotus root soup is discharged through the exhaust pipe 11 and the vertical pipe 12, and the control component 4 controls the second end 26 to be connected with the vertical pipe 12, so that another part of the gas volatilized from the lotus root soup passes through the first end 25, the inclined section 1 23, the vertical section 22 in sequence, and then enters the vertical pipe 12 again through the inclined section 24 and the second end 26, so that the collecting pipe 21 forms a branch for gas flow, and the gas flow will preheat the collecting pipe 21 at this time.

[0070] As the temperature of the volatilized gas becomes higher and higher, the control component 4 controls the connecting pipe 3 to be connected with the vertical section 22, so that the gas in the vertical section 22 enters the injection bottle 13 through the collecting pipe 21, and the hot gas enters the injection bottle 13 and also pushes the cold gas in the injection bottle 13 to enter the vertical pipe 12 through the connecting pipe 3, the second inclined section 24 and the second end 26 in sequence. With the flow of the gas, the gas with a higher temperature enters the injection bottle 13 and the cold gas in the injection bottle 13 is discharged, and the hot gas can also preheat the injection bottle 13.

[0071] When the lotus root soup boils, the temperature of the volatile gas tends to be stable. At this time, the gas entering the sampling bottle 13 is the gas required for detection. As the gas increases, the gas concentration in the sampling bottle 13 reaches the detection requirement. The control component 4 controls the connecting tube 3 to close, and then the sampling bottle 13 can be removed, thereby realizing the collection of the detected gas.

[0072] Alternatively, the control component 4 can also control the second end 26 and the vertical tube 12 to be closed, so that all the gas entering the vertical section 22 enters the injection bottle 13, so that the gas of the required concentration can be collected in the injection bottle 13 more quickly.

[0073] Reference Figure 1 and Figure 2 The control assembly 4 includes a first control valve 41 and a second control valve 42, a humidity sensor 43 and a temperature sensor 44. The first control valve 41 is fixedly mounted on the inclined section 24 and is located at the second end 26. The first control valve 41 controls the second end 26 to be connected or closed with the vertical pipe 12. When connected, the gas in the vertical pipe 12 passes through the inclined section 1 23, the vertical section 22 and the inclined section 2 24 in sequence and then enters the vertical pipe 12. The second control valve 42 is fixedly mounted on the connecting pipe 3. The second control valve 42 is used to control the connecting pipe 3 to be connected or closed with the vertical section 22.

[0074] The humidity sensor 43 and the temperature sensor 44 are fixedly mounted on the inner wall of the second end portion 26, and the humidity sensor 43 and the temperature sensor 44 are used to detect the humidity and temperature of the gas passing through the second end portion 26. A control box for controlling the opening and closing of the first control valve 41 and the second control valve 42 is fixedly mounted on the inclined section 24, and the humidity sensor 43 and the temperature sensor 44 are both electrically connected to the control box, so as to control the opening and closing of the first control valve 41 and the second control valve 42 according to the humidity and temperature of the gas.

[0075] When the lotus root soup boils, the temperature and humidity of the gas tend to be stable, so that the humidity sensor 43 and the temperature sensor 44 detect that the temperature and humidity of the gas tend to a certain value, and the timing starts at this time. Therefore, after a period of time, the gas in the injection bottle 13 reaches the required concentration, so the humidity sensor 43 and the temperature sensor 44 trigger signals to the control box, and the control box controls the second control valve 42 to close.

[0076] Reference Figure 2 and Figure 3 The top of the connecting tube 3 is detachably connected to the injection bottle 13, a mounting tube 31 is fixedly installed at the mouth of the injection bottle 13, the bottom of the mounting tube 31 is threadedly connected to the inner wall of the top of the connecting tube 3, and the axes of the mounting tube 31, the injection bottle 13 and the connecting tube 3 coincide; a sealing and heat-insulating mechanism 6 for sealing and heat-insulating the injection bottle 13 is provided on the mounting tube 31.

[0077] Reference Figure 3 and Figure 4 A mounting hole 32 is provided on the outer wall of the mounting tube 31 , and two mounting holes 32 are arranged in a circular array around the axis of the mounting tube 31 . Two sealing and heat-insulating mechanisms 6 are provided and are respectively located at the two mounting holes 32 .

[0078] The sealing and heat-insulating mechanism 6 includes a sealing plate 61 and a torque piece. The sealing plate 61 is rotatably installed on the mounting hole 32 through a rotating shaft, and the two sealing plates 61 cooperate to block the mounting tube 31 to seal or completely open the mounting tube 31. A layer of heat insulation layer is applied on the side wall of the two sealing plates 61 close to the injection bottle 13. The sealing plate 61 and the heat insulation layer are respectively used to block the gas and heat in the injection bottle 13 from overflowing; the torsion piece is a torsion spring, which is fixedly installed on the side wall of the mounting hole 32 and connected to the sealing plate 61. The torsion piece drives the sealing plate 61 to rotate under the action of elastic force, so that the sealing plate 61 keeps the mounting tube 31 in an open state.

[0079] Reference Figure 3 and Figure 4 A positioning assembly 7 is provided on the mounting tube 31 for positioning the blocking plate 61 when the mounting tube 31 is blocked. The positioning assembly 7 is located on the side of the blocking plate 61 away from the rotating shaft. A mounting groove 33 is provided on the side wall of the mounting tube 31 away from the rotating shaft. The positioning assembly 7 includes a positioning block 71 and a positioning member 72. The positioning block 71 is slidably arranged on the side wall of the mounting groove 33 along the direction approaching or away from the blocking plate 61; two positioning members 72 are provided and are arranged one-to-one with the two blocking plates 61. The positioning member 72 is an elastic spring sheet. The positioning member 72 is pressed against the side wall of the positioning member 72 under the action of elastic force, thereby pushing the positioning block 71 to be inserted and installed on the two blocking plates 61 for positioning.

[0080] After the positioning block 71 is moved away from the sealing plate 61, the sealing plates 61 rotate away from each other under the action of the torque member, so that the two sealing plates 61 fully open the mounting tube 31; when the mounting tube 31 needs to be sealed, the two sealing plates 61 are pushed closer to each other, so that the two sealing plates 61 abut against each other to seal the mounting tube 31, and the positioning block 71 is inserted and installed on the two sealing plates 61 under the action of the positioning member 72 for positioning, thereby achieving sealing or complete opening of the mounting tube 31.

[0081] Reference Figure 3 and Figure 5 The collecting mechanism 2 also includes a heat preservation component 5, which is used to keep the sample injection bottle 13 warm. The heat preservation component 5 includes a heat preservation cover 51 and a heat preservation part 52. The heat preservation cover 51 is fixedly installed on the side wall at the bottle mouth of the sample injection bottle 13, and the axes of the heat preservation cover 51 and the sample injection bottle 13 coincide with each other. At the same time, the heat preservation cover 51 wraps the bottle body of the sample injection bottle 13, and an annular installation space 53 is formed between the inner side wall of the heat preservation cover 51 and the bottle body of the sample injection bottle 13. A replacement port is opened at one end of the heat preservation cover 51 away from the bottle mouth of the sample injection bottle 13. A replacement plate 54 that blocks the replacement port is detachably installed on the heat preservation cover 51 and located at the replacement port by screws. The heat preservation cover 51 can prevent the heat in the installation space 53 from overflowing. At the same time, the heat preservation cover 51 can also provide buffer protection when the sample injection bottle 13 falls.

[0082] The heat-insulating component 52 is annular and is mounted on the installation space 53 by snap-fitting. At the same time, the heat-insulating component 52 is pressed against the body of the sample injection bottle 13, and the heat-insulating component 52 can be taken out through the replacement port for replacement. The heat-insulating component 52 is filled with a liquid that can absorb and release heat, and the liquid is filled as needed, so that the heat-insulating component 52 forms the same heat-absorbing and heat-releasing effect as a hand warmer; when the gas enters the sample injection bottle 13, the gas can heat the liquid in the heat-insulating component 52, and as the gas temperature rises, the heating effect on the liquid becomes more obvious, thereby causing the liquid to heat up rapidly; when the sample injection bottle 13 is removed, the high-temperature liquid in the heat-insulating component 52 can heat and keep the gas in the sample injection bottle 13 warm, thereby improving the heat-insulating effect on the gas in the sample injection bottle 13.

[0083] The working principle of the embodiment of the present application is as follows:

[0084] When boiling lotus root soup, the exhaust pipe 11 starts to exhaust air, and the first control valve 41 opens, so that the gas volatilized by the lotus root soup is discharged through the vertical pipe 12, and another part of the gas volatilized by the lotus root soup passes through the collecting pipe 21 and enters the vertical pipe 12 again. At this time, the gas flow will preheat the collecting pipe 21. As the temperature of the volatilized gas becomes higher and higher, the second control valve 42 opens, so that the gas in the vertical section 22 enters the injection bottle 13 through the collecting pipe 21. The hot gas enters the injection bottle 13 and also pushes the cold gas in the injection bottle 13 to enter the vertical pipe 12 through the connecting pipe 3, the second inclined section 24 and the second end 26 in turn. With the flow of gas, the gas with higher temperature enters the injection bottle 13 and the cold gas in the injection bottle 13 is discharged. The gas entering can also heat the liquid in the insulation part 52.

[0085] When the lotus root soup boils, the required concentration of gas is collected in the sampling bottle 13, and the second control valve 42 is closed. Then the two sealing plates 61 are moved against each other for positioning, and the positioning block 71 is inserted and installed on the two sealing plates 61 under the action of the positioning member 72 for positioning, so as to block the installation tube 31.

[0086] The staff holds the insulation cover 51 and rotates the sampling bottle 13 so that the mounting tube 31 is removed from the connecting tube 3. At this time, the liquid in the insulation part 52 can heat and keep the gas in the sampling bottle 13 warm. Then the mounting tube 31 on the sampling bottle 13 is connected to the gas chromatography-ion mobility mass spectrometry, and the positioning block 71 is pulled to separate from the sealing plate 61. The sealing plates 61 move away from each other under the action of the torsion piece. Therefore, the gas in the sampling bottle 13 enters the gas chromatography-ion mobility mass spectrometry for detection, thereby reducing the probability of danger caused by manual sampling, and also reducing the adverse effects of gas concentration and temperature changes on detection, thereby improving the detection effect and efficiency.

[0087] The embodiment of the present application discloses a detection method for identifying soups.

At the same time, the gas can also heat the liquid in the insulation part 52. When the lotus root soup boils, the required detection gas is collected in the injection bottle 13. As the gas increases, the gas reaches the required concentration.
