Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to airflow regulation equipment in air conditioning and ventilation systems, and more particularly to an air conditioning air delivery device. Background Technology

[0002] Smoke simulation technology is widely used in aerospace training, emergency response training, and industrial safety testing. It aims to recreate fire smoke environments in a controlled manner to assess personnel response capabilities, test emergency plans, and evaluate the performance of detection equipment. Existing smoke simulation systems typically use a smoke generator to heat and vaporize a smoke-generating liquid (such as glycerol-based or mineral oil-based smoke-generating liquids). The vapor enters a pipe, condenses to form an aerosol, and is transported into the simulated space, where it forms visible white smoke.

[0003] In actual fire scenarios, if the fire source is near the air conditioning return air vent or the air conditioning system itself is affected, and the system fails to shut down in time or the fire damper malfunctions, smoke may be drawn into the air conditioning ducts and rapidly spread to multiple areas. During this process, the smoke concentration exhibits typical dynamic changes: initially, due to the infiltration of a small amount of smoke, the concentration at the outlet is low; however, as the fire intensifies and a large amount of smoke continues to enter the system, the smoke concentration at the air conditioning outlet will rise sharply in a short period of time, forming a dangerous state of rapid "low-high" increase.

[0004] However, due to the limitations of the smoke generation device in terms of smoke output speed and concentration adjustment capabilities, it is difficult to realize the dynamic evolution process from the initial low concentration stage to the sudden high concentration burst, thus affecting the realism of the simulated scene and the reliability of the training effect.

Detailed Implementation

[0032] Because the smoke generating device is limited by the smoke output speed and concentration adjustment capability, it is difficult to realize the dynamic evolution process from the initial low concentration stage to the sudden high concentration burst, thus affecting the realism of the simulated scene and the reliability of the training effect.

[0033] In view of this, this solution provides an air conditioning air supply device, including a pre-storage mechanism 100.

[0034] The following combination Figures 1-5 The structure and shape of the air conditioning air supply device are described in detail:

[0035] The pre-storage mechanism 100 is communicated with the aerosol generator at one end and with the air conditioner air supply pipe at the other end to form a conveying path for guiding the aerosol generator to output the aerosol into the simulation space; the pre-storage mechanism 100 is configured to be able to expand and contract in the axial direction; when the pre-storage mechanism 100 expands in the axial direction, the volume gradually increases to accommodate part of the aerosol, thereby reducing the amount of aerosol entering the air conditioner air supply pipe;

[0036] When the pre-storage mechanism 100 contracts in the axial direction, the volume gradually decreases to make the aerosol accumulated in the pre-storage mechanism 100 enter the air conditioner air supply pipe.

[0037] In the embodiment, in the low-concentration stage of smoke simulation, the pre-storage mechanism 100 expands in the axial direction to gradually increase the volume of the pre-storage mechanism 100, thereby accommodating part of the aerosol entering the air conditioner air supply pipe through the pre-storage mechanism 100, so as to reduce the amount of aerosol entering the air conditioner air supply pipe, thereby simulating the scene in which the low-concentration smoke in the simulation space at the initial stage of the fire because a small amount of smoke penetrates into the air conditioning system, resulting in a low smoke concentration at the outlet of the air conditioner.

[0038] In the high-concentration burst stage of smoke simulation, the pre-storage mechanism 100 contracts in the axial direction to gradually reduce the volume of the pre-storage mechanism 100, thereby driving the aerosol accumulated in the pre-storage mechanism 100 to enter the air conditioner air supply pipe to instantaneously increase the amount of aerosol entering the air conditioner air supply pipe, thereby simulating the scene in which the smoke continues to enter the air conditioning system in large quantities as the fire intensifies, resulting in a sharp rise in smoke concentration at the outlet of the air conditioner in a short period of time in the simulation space.

[0039] In order to simulate the high-temperature characteristics of smoke while maintaining the dispersion stability and fluidity of the aerosol:

[0040] As shown in Figures 1-2 , the preheating mechanism 200 is further included; the preheating mechanism 200 is communicated between the aerosol generator and the pre-storage mechanism 100 and is used to heat the gaseous medium flowing therethrough.

[0041] In the embodiment, the aerosol generated by the aerosol generator enters the pre-storage mechanism 100 through the preheating mechanism 200, and in this process, the preheating mechanism 200 heats the aerosol flowing therethrough to maintain the temperature of the aerosol in a predetermined range, thereby avoiding condensation or wall sticking of the aerosol due to temperature reduction during the conveying process, so as to maintain the dispersion stability and fluidity of the aerosol.

[0042] In addition, the aerosol heated to the predetermined range of temperature in the pre-storage mechanism 100 enters the simulation space through the air conditioner air supply pipe to simulate the high-temperature characteristics of the smoke generated by the fire, thereby further enhancing the authenticity of the aerosol imitating smoke in the simulation space.

[0043] In order to avoid the deposition of aerogel in the preheating mechanism 200:

[0044] As shown in Figure 4As shown in the figure, the preheating mechanism 200 comprises a preheating cylinder 210 and a light-heat tube 220; the preheating cylinder 210 comprises a cylinder body 211 and a light-transmitting plate 212 installed on the cylinder body 211; one end of the cylinder body 211 is connected to the smoke generator, and the other end is connected to the pre-storage mechanism 100; the light-heat tube 220 is arranged outside the cylinder body 211, and the light radiation output by the light-heat tube 220 passes through the light-transmitting plate 212 and enters the cylinder body 211, thereby heating the aerosol flowing through the preheating cylinder 210.

[0045] In order to guide the light radiation output by the light-heat tube 220 to pass through the light-transmitting plate 212:

[0046] As shown in the figure, the preheating mechanism 200 further comprises a light-collecting cover 230; the light-collecting cover 230 is installed on the cylinder body 211 and located outside the light-heat tube 220, and is used to collect the light radiation emitted by the light-heat tube 220 and guide the light radiation to pass through the light-transmitting plate 212 and enter the cylinder body 211. Figure 4

[0047] In this embodiment, the aerosol generated by the smoke generator enters the pre-storage mechanism 100 through the preheating cylinder 210, and in this process, part of the light radiation generated by the light-heat tube 220 passes through the light-transmitting plate 212 and enters the cylinder body 211, and the other part of the light radiation is refracted and guided by the light-collecting cover 230 to pass through the light-transmitting plate 212 and enter the cylinder body 211, and the light radiation heats the aerosol in the cylinder body 211, and in this process, the heat source does not directly contact the aerosol, thereby avoiding the deposition and sintering of the aerosol and the heat source caused by the direct contact between the aerosol and the heat source, and reducing the mutual influence between the aerosol and the heat source.

[0048] The type of the light-transmitting plate 212 includes but is not limited to quartz glass, and the type of the light-heat tube 220 includes but is not limited to infrared light.

[0049] In order to reduce the condensation speed of the aerosol before entering the air conditioner air supply pipe:

[0050] As shown in the figure, the pre-storage mechanism 100 comprises a folding storage cylinder 110 and a first gas conveying valve 120; the folding storage cylinder 110 is connected to the preheating mechanism 200 and is configured to be able to expand and contract along the axial direction; one end of the first gas conveying valve 120 is connected to the folding storage cylinder 110, and the other end is connected to the air conditioner air supply pipe, and is used to control the on-off between the folding storage cylinder 110 and the air conditioner air supply pipe; when the flow channel between the pre-storage mechanism 100 and the smoke generator is preheated, the first gas conveying valve 120 is closed, and at the same time, the folding storage cylinder 110 reciprocally expands and contracts along the axial direction, so as to drive the gas to reciprocally flow through the folding storage cylinder 110, the preheating mechanism 200 and the smoke generator in sequence, and to be continuously heated by the preheating mechanism 200. Figures 2-3

[0051] ​​In the smoke simulation preparation stage, the first gas inlet valve 120 controls the folding storage cylinder 110 to be disconnected from the air conditioner air supply pipe, and then the folding storage cylinder 110 is stretched along the axial direction to increase the volume of the folding storage cylinder 110 and generate negative pressure, thereby driving the ambient air to enter the folding storage cylinder 110 in sequence through the smoke generator and the preheating mechanism 200, and then the folding storage cylinder 110 is contracted along the axial direction to reduce the volume of the folding storage cylinder 110, thereby driving the air in the folding storage cylinder 110 to be discharged in sequence through the preheating mechanism 200 and the smoke generator. During this process, the preheating mechanism 200 heats the air flowing through it, and the heated gas heats the folding storage cylinder 110 and the flow channel between the folding storage cylinder 110 and the smoke generator, thereby reducing the condensation speed of the aerosol before entering the air conditioner air supply pipe.

[0052] In order to avoid the condensation and settlement of the aerosol in the folding storage cylinder 110:

[0053] As shown in Figures 1-3 , it also includes a flow guide structure 300; the flow guide structure 300 includes a circulating pipe 310; the pre-storage mechanism 100 also includes a folding circulating cylinder 130; the folding circulating cylinder 130 is connected to the folding storage cylinder 110 and is configured to be able to stretch and contract along the axial direction; one end of the circulating pipe 310 is communicated with the folding storage cylinder 110, and the other end is communicated with the folding circulating cylinder 130; when the pre-storage mechanism 100 is stretched to accommodate the aerosol, the folding circulating cylinder 130 moves along the axial direction while reciprocating and stretching and contracting, while the folding storage cylinder 110 synchronously and reversely stretches and contracts relative to the folding circulating cylinder 130, to drive the aerosol to flow reciprocally along the folding storage cylinder 110, the circulating pipe 310 and the folding circulating cylinder 130.

[0054] In order to further increase the dispersion stability and flowability of the aerosol in the folding circulating cylinder 130:

[0055] As shown in Figure 3 , the flow guide structure 300 also includes a circulating tee 320; the first port of the circulating tee 320 is communicated with the circulating pipe 310, the second port is communicated with the preheating mechanism 200, and the third port is communicated with the smoke generator; when the pre-storage mechanism 100 is stretched to accommodate the aerosol, the aerosol flows reciprocally along the folding storage cylinder 110, the preheating mechanism 200, the circulating tee 320, the circulating pipe 310 and the folding circulating cylinder 130, and passes through the preheating mechanism 200.

[0056] In the embodiment, in the low concentration stage of smoke simulation, the folding circulating cylinder 130 moves along the axial direction while reciprocating, and the folding storage cylinder 110 synchronously and reversely reciprocates relative to the folding circulating cylinder 130, so as to form extrusion thrust and vacuum suction at both ends of the passage formed by the preheating mechanism 200, the circulating tee 320 and the circulating pipe 310. Under the double action of the extrusion thrust and the vacuum suction, the aerosol reciprocates along the folding storage cylinder 110, the preheating mechanism 200, the circulating tee 320, the circulating pipe 310 and the folding circulating cylinder 130, thereby avoiding the condensation and deposition of the aerosol in the folding storage cylinder 110. In the process, the preheating mechanism 200 heats the aerosol flowing therethrough, thereby further increasing the dispersion stability and flowability of the aerosol in the folding circulating cylinder 130.

[0057] In order to improve the stability of the aerosol delivery in the low concentration stage of smoke simulation:

[0058] As shown in Figures 2-3 , the pre-storage mechanism 100 further comprises a second gas delivery valve 140; one end of the second gas delivery valve 140 is communicated with the folding circulating cylinder 130, and the other end is communicated with the air conditioner air supply pipe;

[0059] When the pre-storage mechanism 100 is stretched to accommodate the aerosol, the first gas delivery valve 120 is opened by following the contraction of the folding storage cylinder 110, so that the folding storage cylinder 110 is communicated with the air conditioner air supply pipe; the second gas delivery valve 140 is opened by following the contraction of the folding circulating cylinder 130, so that the folding circulating cylinder 130 is communicated with the air conditioner air supply pipe.

[0060] In the embodiment, in the low concentration stage of smoke simulation, the first gas delivery valve 120 and the second gas delivery valve 140 are respectively closed or opened by following the expansion or contraction of the folding storage cylinder 110 and the folding circulating cylinder 130, so as to control the communication between the folding storage cylinder 110 and the folding circulating cylinder 130 and the air conditioner air supply pipe during the contraction, thereby driving the aerosol in the folding storage cylinder 110 or the folding circulating cylinder 130 to enter the air conditioner air supply pipe through the contraction, so as to improve the stability of the aerosol delivery in the low concentration stage of smoke simulation.

[0061] In order to avoid the mutual interference between the aerosol generated by the smoking device and the aerosol accumulated in the pre-storage mechanism 100 during the process of entering the air supply pipe:

[0062] As shown in Figures 2-3As shown, the flow guide structure 300 further comprises an air inlet three-way valve 330 and a diversion three-way valve 340; the first port of the air inlet three-way valve 330 is in communication with the aerosol generator, the second port is in communication with the first port of the diversion three-way valve 340, and the third port is in communication with the third port of the circulation three-way valve 320; the second port of the diversion three-way valve 340 is in communication with the circulation pipe 310, and the third port is in communication with the third port of the circulation three-way valve 320; when the pre-storage mechanism 100 is contracted to output the aerosol, the folded storage cartridge 110 is axially contracted to drive the aerosol stored in the folded storage cartridge 110 to enter the air supply pipe through the first air delivery valve 120; at the same time, the aerosol generated by the aerosol generator enters the air supply pipe through the air inlet three-way valve 330, the diversion three-way valve 340, the circulation pipe 310, the folded circulation cartridge 130, and the second air delivery valve 140 in sequence.

[0063] In this embodiment, during the smoke simulation sudden high concentration burst phase, the folded storage cartridge 110 is in an expanded state, and the folded circulation cartridge 130 is in a compressed state. Then, the air inlet three-way valve 330 and the diversion three-way valve 340 control the aerosol generator to be in communication with the circulation pipe 310, so that the aerosol generated by the aerosol generator enters the air supply pipe through the air inlet three-way valve 330, the diversion three-way valve 340, the circulation pipe 310, the folded circulation cartridge 130, and the second air delivery valve 140 in sequence.

[0064] Then, the expanded folded storage cartridge 110 is axially contracted, and the folded circulation cartridge 130 is axially moved to reduce the volume of the folded storage cartridge 110, so as to drive the aerosol stored in the folded storage cartridge 110 to enter the air supply pipe through the first air delivery valve 120.

[0065] During this process, the aerosol generated by the aerosol generator and the aerosol stored in the folded storage cartridge 110 enter the air supply pipe along different paths respectively, so as to avoid mutual interference of the aerosol generated by the aerosol generator and the aerosol stored in the folded storage cartridge 110 during the process of entering the air supply pipe.

[0066] In order to reduce the aerosol loss and reduce the working pressure of the aerosol generator and the smoke removal device:

[0067] As Figures 2-3As shown, the flow guide structure 300 further comprises a backflow three-way valve 350; a first port of the backflow three-way valve 350 is in communication with a third port of the air inlet three-way valve 330, a second port is in communication with an exhaust pipe, and a third port is in communication with a first port of the circulation three-way valve 320; the exhaust pipe is used to exhaust aerosol in the simulation space; when the aerosol contained in the pre-storage mechanism 100 is completed, the aerosol in the simulation space is sequentially returned to the simulation space through the exhaust pipe, the backflow three-way valve 350, the circulation three-way valve 320, the preheating mechanism 200, the folding storage cylinder 110, the first air conveying valve 120 and the air conditioner air supply pipe, and is heated by the preheating mechanism 200; at the same time, the aerosol generated by the smoking device is sequentially introduced into the air conditioner air supply pipe through the air inlet three-way valve 330, the diversion three-way valve 340, the circulation pipe 310, the folding circulation cylinder 130 and the second air conveying valve 140.

[0068] In this embodiment, in order to simulate the smoke inhalation into the air conditioner pipeline in the actual fire scene, it is necessary to exhaust the air and aerosol in the simulation space through the exhaust pipe, and in order to avoid the leakage of aerosol in the simulation space, it is necessary to ensure that the simulation space is in a micro-negative pressure state. The above environmental requirements include but are not limited to flight simulators. Since the amount of gas discharged by keeping the simulation space in a micro-negative pressure state is less than the amount of gas discharged by the exhaust pipe in the simulation of the actual fire scene, part of the aerosol is lost, and the working pressure of the smoking device and the smoke removal equipment is increased.

[0069] In order to solve the above problems, in the high-concentration stable stage of the smoke simulation, the backflow three-way valve 350 controls the exhaust pipe to be in communication with the circulation three-way valve 320, so that part of the aerosol and air in the exhaust pipe are sequentially introduced into the preheating mechanism 200 through the backflow three-way valve 350 and the circulation three-way valve 320 and heated, and the heated aerosol and air are sequentially returned to the simulation space through the folding storage cylinder 110, the first air conveying valve 120 and the air conditioner air supply pipe, so as to recycle the aerosol in the simulation space, thereby reducing the amount of aerosol generated by the smoking device and the amount of aerosol purified by the smoke removal equipment, and thereby reducing the working pressure of the smoking device and the smoke removal equipment.

[0070] At the same time, the aerosol generated by the smoking device is sequentially introduced into the air conditioner air supply pipe through the air inlet three-way valve 330, the diversion three-way valve 340, the circulation pipe 310, the folding circulation cylinder 130 and the second air conveying valve 140, so that the aerosol generated by the smoking device and the recycled aerosol in the simulation space enter the air supply pipe along different paths, thereby avoiding interference between the aerosol generated by the smoking device and the recycled aerosol in the simulation space during the process of entering the air supply pipe.

[0071] In order to drive the folding storage cylinder 110 and the folding circulation cylinder 130 to move independently:

[0072] As Figure 1 and Figure 5As shown, the execution mechanism 400 further comprises a circular support 410, a storage support 420 and two driving structures 430; the circular support 410 is connected to the folding circulating cylinder 130; the storage support 420 is connected to the folding storage cylinder 110; the two driving structures 430 are respectively used to drive the circular support 410 and the storage support 420 to move along the axial direction of the pre-storage mechanism 100.

[0073] In order to ensure the stability of the circular support 410 and the storage support 420 during the movement:

[0074] As shown in the figure, Figure 5 the execution mechanism 400 further comprises a guide circular rail 440 and a bearing support 450; the guide circular rail 440 is inserted and assembled with the bearing support 450; the circular support 410 and the storage support 420 are both sleeved on the guide circular rail 440 and are in sliding connection with the guide circular rail 440.

[0075] In order to drive the circular support 410 or the storage support 420 to move along the axial direction of the pre-storage mechanism 100 by the driving structure 430:

[0076] As shown in the figure, Figure 5 the driving structure 430 comprises a driving motor 431 and a screw rod 432; the driving motor 431 is installed on the bearing support 450, and its rotating shaft is connected to the screw rod 432; the circular support 410 and the storage support 420 are both sleeved on the screw rod 432 and are screwed with the screw rod 432.

[0077] In this embodiment, the two driving structures 430 respectively drive the circular support 410 and the storage support 420 to move along the guide circular rail 440, and the circular support 410 and the storage support 420 cooperate to drive the folding circulating cylinder 130 to move or stretch along the axial direction, and the storage support 420 drives the folding storage cylinder 110 to stretch along the axial direction, so as to drive the folding storage cylinder 110 and the folding circulating cylinder 130 to move independently.

[0078] In the above process, the guide circular rail 440 guides the circular support 410 and the storage support 420 to move along a straight line, so as to ensure that the folding storage cylinder 110 stretches along the axial direction, and that the folding circulating cylinder 130 stretches and moves along the axial direction; at the same time, the guide circular rail 440 and the driving structure 430 both provide support during the movement of the circular support 410 or the storage support 420, thereby transmitting and reducing the deflection stress generated during the movement of the circular support 410 or the storage support 420, so as to ensure the stability of the circular support 410 and the storage support 420 during the movement.

[0079] When the driving structure 430 drives the circular support 410 or the storage support 420 to move, the driving motor 431 drives the screw rod 432 to rotate, and the screw rod 432 drives the circular support 410 or the storage support 420 to move along the guide circular rail 440 through thread cooperation.

[0080] The application further provides a method for using the air conditioner air conveying device, comprising the following steps:

[0081] OP1 smoke simulation preparation stage: the actuator 400 drives the pre-storage mechanism 100 to axially extend and retract, so that the air flows back and forth along the smoke generator, the flow guide structure 300, the preheating mechanism 200 and the pre-storage mechanism 100 in sequence, in the process, the preheating mechanism 200 heats the air flowing through, so as to preheat the flow channel between the pre-storage mechanism 100 and the smoke generator;

[0082] After the flow channel between the pre-storage mechanism 100 and the smoke generator is preheated, the actuator 400 drives the folding storage cylinder 110 and the folding circulation cylinder 130 to synchronously and reversely extend and retract, so that the air moves back and forth along the folding storage cylinder 110, the flow guide structure 300, the preheating mechanism 200 and the folding circulation cylinder 130 in sequence, in the process, the preheating mechanism 200 heats the air flowing through, so as to preheat the pre-storage mechanism 100.

[0083] In this step:

[0084] The first air conveying valve 120 controls the folding storage cylinder 110 to be disconnected with the air conditioner air conveying pipe, then the two drive structures 430 drive the circulation support 410 and the storage support 420 to move at the same speed in the extension direction, so as to drive the folding storage cylinder 110 to extend in the axial direction, thereby increasing the volume of the folding storage cylinder 110 and generating suction, so that the ambient air enters the folding storage cylinder 110 through the smoke generator, the air inlet three-way valve 330, the backflow three-way valve 350, the circulation three-way valve 320 and the preheating mechanism 200 in sequence, then the two drive structures 430 drive the circulation support 410 and the storage support 420 to move at the same speed in the contraction direction along the guide circular rail 440, so as to drive the folding storage cylinder 110 to contract in the axial direction, thereby reducing the volume of the folding storage cylinder 110, so as to drive the air in the folding storage cylinder 110 to be discharged through the preheating mechanism 200, the circulation three-way valve 320, the backflow three-way valve 350, the air inlet three-way valve 330 and the smoke generator in sequence, and the above steps are repeated, so as to drive the air to flow back and forth along the smoke generator, the flow guide structure 300, the preheating mechanism 200 and the pre-storage mechanism 100 in sequence, in the process, the preheating mechanism 200 heats the air flowing through, so as to preheat the flow channel between the pre-storage mechanism 100 and the smoke generator.

[0085] After the preheating of the flow channel between the pre-storing mechanism 100 and the smoking device, the second air feeding valve 140 controls the disconnection of the folding circulating cylinder 130 and the air conditioner air feeding pipe, the air feeding three-way valve 330 or the backflow three-way valve 350 controls the disconnection of the circulating three-way valve 320 and the smoking device, the turning three-way valve 340 controls the connection of the circulating pipe 310 and the circulating three-way valve 320, then the driving mechanism 430 drives the storage support 420 to move back and forth along the guide circular rail 440, so that the folding storage cylinder 110 and the folding circulating cylinder 130 are synchronously and reversely stretched and contracted, and then the air is driven to flow back and forth along the folding storage cylinder 110, the preheating mechanism 200, the circulating three-way valve 320, the circulating pipe 310 and the folding circulating cylinder 130, and in this process, the preheating mechanism 200 heats the air flowing therethrough to preheat the pre-storing mechanism 100.

[0086] OP2 smoke simulation low concentration stage: the actuator 400 drives the pre-storing mechanism 100 to axially stretch, so that the volume of the pre-storing mechanism 100 gradually increases, thereby accommodating part of the aerosol flowing through the pre-storing mechanism 100, so as to reduce the amount of aerosol entering the air conditioner air feeding pipe.

[0087] In this step:

[0088] One driving mechanism 430 drives the circulating support 410 to move in the stretching direction, and the other driving mechanism 430 drives the storage support 420 to move back and forth along the guide circular rail 440, so that the pre-storing mechanism 100 is axially stretched while the folding storage cylinder 110 and the folding circulating cylinder 130 are synchronously and reversely stretched and contracted, and in this process, the volume of the pre-storing mechanism 100 gradually increases, thereby accommodating part of the aerosol flowing through the pre-storing mechanism 100, so as to reduce the amount of aerosol entering the air conditioner air feeding pipe.

[0089] When the folding storage cylinder 110 and the folding circulating cylinder 130 are synchronously and reversely stretched and contracted, the extrusion pushing force and the vacuum suction force are respectively applied at both ends of the passage formed by the preheating mechanism 200, the circulating three-way valve 320, the turning three-way valve 340 and the circulating pipe 310, and under the double action of the extrusion pushing force and the vacuum suction force, the aerosol flows back and forth along the folding storage cylinder 110, the preheating mechanism 200, the circulating three-way valve 320, the turning three-way valve 340, the circulating pipe 310 and the folding circulating cylinder 130 in turn, and in this process, the preheating mechanism 200 heats the aerosol flowing therethrough, thereby driving the aerosol to flow while heating it.

[0090] In the above process, when the folding storage cylinder 110 or the folding circulation cylinder 130 is contracted, the first air conveying valve 120 or the second air conveying valve 140 is opened following the contraction of the folding storage cylinder 110 or the folding circulation cylinder 130, so that the aerosol in the folding storage cylinder 110 or the folding circulation cylinder 130 enters the air conditioner air supply pipe through the first air conveying valve 120 or the second air conveying valve 140; when the folding storage cylinder 110 or the folding circulation cylinder 130 is expanded, the vacuum suction generated in the expansion process accelerates the driving of the aerosol delivered by the smoking device to enter the circulation tee joint 320 in turn through the air inlet tee joint 330 and the backflow tee joint 350, the aerosol delivered by the smoking device in the circulation tee joint 320 is mixed with the reciprocating flow aerosol and enters the folding storage cylinder 110 or the folding circulation cylinder 130 in the contracted state.

[0091] OP3: The simulation of the sudden high-concentration burst phase of smoke: the actuator 400 drives the pre-storage mechanism 100 to contract in the axial direction, so as to reduce the volume of the pre-storage mechanism 100, and then drive the aerosol stored in the pre-storage mechanism 100 to enter the air conditioner air supply pipe.

[0092] In this step: the driving structure 430 drives the storage support 420 to move in the expansion direction, so as to drive the folding storage cylinder 110 to expand and the folding circulation cylinder 130 to contract at the same time, and then the aerosol in the folding circulation cylinder 130 enters the folding storage cylinder 110, and then the air inlet tee joint 330 and the diversion tee joint 340 control the communication between the smoking device and the circulation pipe 310, so that the aerosol delivered by the smoking device enters the air conditioner air supply pipe in turn through the air inlet tee joint 330, the diversion tee joint 340, the circulation pipe 310, the folding circulation cylinder 130 and the second air conveying valve 140, and then the two driving structures 430 respectively drive the circulation support 410 and the storage support 420 to move in the contraction direction, so as to contract the folding storage cylinder 110 in the axial direction, and then reduce the volume of the folding storage cylinder 110, so that the aerosol in the folding storage cylinder 110 enters the air conditioner air supply pipe through the first air conveying valve 120.

[0093] OP4: The simulation of the high-concentration stable phase of smoke: part of the aerosol in the smoke exhaust pipe from the simulation space enters the simulation space in turn through the backflow tee joint 350, the circulation tee joint 320, the preheating mechanism 200, the pre-storage mechanism 100 and the air conditioner air supply pipe.

[0094] In this step: the backflow tee joint 350 controls the communication between the smoke exhaust pipe and the circulation tee joint 320, so that part of the aerosol and air in the smoke exhaust pipe enters the preheating mechanism 200 in turn through the backflow tee joint 350 and the circulation tee joint 320 and is heated, and then the heated aerosol and air enter the simulation space in turn through the folding storage cylinder 110, the first air conveying valve 120 and the air conditioner air supply pipe.

[0095] Meanwhile, the air inlet three-way valve 330 and the steering three-way valve 340 control the smoke generator to communicate with the circulation pipe 310, so that the aerosol delivered by the smoke generator enters the air conditioner air supply pipe in sequence through the air inlet three-way valve 330, the steering three-way valve 340, the circulation pipe 310, the folding circulation cylinder 130 and the second air inlet valve 140.

[0096] The OP5 smoke simulation termination stage: the smoke generator and the aerosol between the smoke generator and the guide structure 300 enter the smoke exhaust pipe in sequence through the air inlet three-way valve 330 and the return three-way valve 350; in addition, the actuator 400 drives the pre-storage mechanism 100 to extend and retract along the axis, so as to drive the aerosol in the pre-storage mechanism 100 to enter the smoke exhaust pipe through the guide structure 300, and to suck the air in the air conditioner air supply pipe into the pre-storage mechanism 100.

[0097] In this step: the air inlet three-way valve 330 and the return three-way valve 350 control the smoke generator to communicate with the smoke exhaust pipe, and then the smoke generator drives the aerosol in the interior and between the smoke generator and the guide structure 300 to enter the smoke exhaust pipe in sequence through the air inlet three-way valve 330 and the return three-way valve 350.

[0098] After the aerosol in the smoke generator is exhausted, the return three-way valve 350 controls the circulation three-way valve 320 to communicate with the smoke exhaust pipe, the steering three-way valve 340 controls the circulation pipe 310 to communicate with the circulation three-way valve 320, and then the first air inlet valve 120 and the second air inlet valve 140 control the folding storage cylinder 110 and the folding circulation cylinder 130 to communicate with the air conditioner air supply pipe, respectively.

[0099] Then the two drive structures 430 drive the circulation support 410 and the storage support 420 to extend along the axis, respectively, so that the folding storage cylinder 110 and the folding circulation cylinder 130 extend along the axis, and then the air in the air conditioner air supply pipe enters the folding storage cylinder 110 and the folding circulation cylinder 130 through the first air inlet valve 120 and the second air inlet valve 140, respectively, and then the first air inlet valve 120 and the second air inlet valve 140 control the folding storage cylinder 110 and the folding circulation cylinder 130 to be disconnected with the air conditioner air supply pipe, respectively, and then the two drive structures 430 drive the circulation support 410 and the storage support 420 to retract along the axis, respectively, so that the folding storage cylinder 110 and the folding circulation cylinder 130 retract along the axis, and then the aerosol in the folding storage cylinder 110 enters the smoke exhaust pipe in sequence through the preheating mechanism 200, the circulation three-way valve 320 and the return three-way valve 350, and the aerosol in the folding circulation cylinder 130 enters the smoke exhaust pipe in sequence through the circulation pipe 310, the steering three-way valve 340, the circulation three-way valve 320 and the return three-way valve 350, and the above steps are repeated until the residual aerosol in the device is exhausted.
