Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an air guiding device, a fixing structure, and a testing device. Background Technology

[0002] An electronic atomizing device is a device used to generate aerosols.

[0003] Traditional technologies for testing electronic atomization devices typically require customized fixtures for different models to achieve sealing and positioning. The operation steps are cumbersome and have poor compatibility. Furthermore, traditional technologies lack methods for precisely controlling parameters such as the diffusion shape and concentration distribution of aerosols in open spaces.

[0004] The above information disclosed in the background art of this application is only for understanding the background of the concept of this application, and does not indicate or imply that it includes information of the prior art. Utility Model Content

[0005] Therefore, it is necessary to provide a gas guiding device, a fixing structure, and a testing device to address the above problems.

[0006] This application provides a gas guiding device, which includes:

[0007] An air guiding device is provided, which includes an air inlet channel, a through hole, and a nozzle. The nozzle is located around the periphery of the through hole. The air inlet channel communicates with the through hole through the nozzle. The through hole is used to communicate with the air outlet of the electronic atomizing device. The air inlet channel can introduce gas and make the gas spray out from the nozzle to guide the aerosol from the air outlet of the electronic atomizing device to flow out.

[0008] The aforementioned air guiding device can achieve at least the following beneficial effects: By setting nozzles around the through-hole, the gas introduced through the air inlet channel is ejected from the nozzles to form a directional airflow. Understandably, the pressure is lower in areas with higher flow rates, and this negative pressure effectively guides the aerosol generated by the electronic atomization device outwards and flows in a preset direction, preventing disorderly aerosol diffusion and ensuring the stability and consistency of aerosol transmission during testing. By adjusting the gas flow rate or pressure in the air inlet channel, the airflow velocity at the nozzles can be precisely controlled, thereby achieving dynamic regulation of the aerosol flow state, meeting different testing standards or research needs, and enhancing the application range and testing accuracy of the equipment.

[0009] In some embodiments, the air guiding device includes a housing and a guide member. The housing has a mounting groove, and a boss is formed at the bottom of the mounting groove. A through hole is formed on the boss. The guide member is sealed and embedded in the mounting groove, forming an air guiding space with the groove wall. An air inlet channel is formed inside the housing, communicating with the air guiding space. An air passage is formed on the guide member, communicating with the through hole. The wall of the air passage and the outer peripheral surface of the boss form the nozzle. By designing the air guiding device as a separate structure of the housing and the guide member, the guide member can be independently disassembled for easy cleaning or replacement, avoiding aerosol residue affecting test accuracy. The guide member can be fixed to the mounting groove through a sealed embedding method, ensuring airtightness and simplifying the assembly process, such as with snap-fit ​​or threaded connections, reducing manufacturing costs. The air guide is sealed and embedded in the mounting groove of the housing and forms an air guiding space with the groove wall, so that the airflow in the air intake channel is evenly distributed to the nozzle; at the same time, the air passage of the air guide and the outer peripheral surface of the boss form a nozzle at intervals, ensuring that the airflow is directionally ejected along the periphery of the through hole, effectively guiding the flow of aerosol and avoiding turbulence interference.

[0010] In some embodiments, the vent is directly opposite the through hole. By aligning the vent of the guide with the through hole, the airflow can pass directly through the through hole along a straight path, reducing energy loss and turbulence interference caused by airflow deflection and ensuring detection accuracy.

[0011] In some embodiments, both the vent and the through-hole are circular holes and coaxially arranged. By designing both the vent and the through-hole as circular holes and arranging them coaxially, the airflow can flow axially, effectively reducing eddy currents and pressure drop losses, and improving the stability and uniformity of aerosol delivery. Simultaneously, the coaxial circular hole structure facilitates processing and assembly, ensuring the alignment accuracy between the guide component and the housing. Furthermore, this design can optimize the airflow velocity distribution by adjusting the diameter ratio of the circular holes, allowing the aerosol to form a more concentrated flow path in the test area, further improving the repeatability and reliability of the test results.

[0012] In some embodiments, the inner profile of the vent is larger than the outer profile of the boss. A nozzle structure is formed between the two by making the inner profile of the vent larger than the outer profile of the boss.

[0013] In some embodiments, the flow guide includes a first flow guide plate, a second flow guide plate, and a flow guide column. The first flow guide plate and the second flow guide plate are stacked along the thickness direction and connected by the flow guide column. The air passage hole penetrates the first flow guide plate, the flow guide column, and the second flow guide plate. The first flow guide plate is sealed and covered in the mounting groove. The second flow guide plate is embedded in the mounting groove and divides the air guiding space into a first air guiding space and a second air guiding space. The second flow guide plate has an air guiding hole. The first air guiding space communicates with the second air guiding space through the air guiding hole. The first air guiding space communicates with the air intake channel, and the second air guiding space communicates with the nozzle. The flow guide adopts a layered structure design, including a stacked first flow guide plate and a second flow guide plate, which are connected and fixed by the flow guide column. The air passage hole penetrates the first flow guide plate, the flow guide column, and the second flow guide plate to form a continuous airflow channel. The first flow guide plate is sealed and covered at the top of the mounting groove. The second flow guide plate is embedded in the mounting groove and divides the air guiding space into a first air guiding space and a second air guiding space that are interconnected. The first air guide space is connected to the air intake channel, and the second air guide space receives the airflow from the first air guide space through air guide holes on the second guide plate and guides it to the nozzle. This structure optimizes the airflow path through layered air guidance and spatial separation, ensuring a smooth transition and uniform distribution of airflow, avoiding turbulence interference, and enhancing sealing and structural stability, making it suitable for high-precision pneumatic control systems.

[0014] In some embodiments, a guide section is formed at the bottom of the mounting groove, and the guide section and the outer peripheral surface of the boss form a guide groove. The second guide plate is placed on the guide groove and forms the second air guiding space together with the guide groove. The bottom of the mounting groove is provided with a guide section, which together with the outer peripheral surface of the boss forms a guide groove. The second guide plate covers the guide groove and cooperates with the guide groove to form the second air guiding space. This design guides the airflow along a predetermined path through the guide groove, so that the airflow is initially rectified before entering the second air guiding space, further reducing turbulence interference. The second air guiding space is connected to the first air guiding space through the air guiding hole, and finally the airflow is smoothly delivered to the nozzle. This structure optimizes the uniformity of airflow distribution and enhances the guiding efficiency, making it suitable for aerosol transport or precision gas control scenarios with high requirements for airflow stability.

[0015] In some embodiments, the number of guide sections is set to multiple, and the multiple guide sections are arranged at intervals along the circumference of the boss on the outer periphery of the boss. A guide groove is formed between any two adjacent guide sections. The number of nozzles is also set to multiple, and the multiple nozzles are arranged at intervals along the circumference of the through hole. The guide grooves correspond one-to-one with the nozzles. The multiple guide sections are evenly spaced along the circumference of the boss, and independent guide grooves are formed between adjacent guide sections. This annular array design can realize multi-channel flow diversion of airflow, avoid flow overload of a single path, and improve the symmetry and uniformity of gas distribution. The number of nozzles corresponds one-to-one with the guide grooves and is equidistantly distributed along the circumference of the through hole, ensuring that the airflow of each guide groove is independently guided to the matching nozzle. Through the multi-nozzle structure design surrounding the through hole, the directional airflow introduced by the air intake channel forms an annular air curtain, which can effectively guide the aerosol generated by the electronic atomization device to flow in a preset direction, avoid disorderly diffusion of aerosols, and ensure the stability and consistency of aerosol transmission during testing.

[0016] In some embodiments, the guide channel gradually narrows towards the protrusion. This can be considered as the cross-sectional area of ​​the guide channel or the second air guide space gradually decreasing towards the protrusion (i.e., a tapering design). This tapering structure accelerates airflow and creates a local low-pressure zone at the end of the guide channel through the Venturi effect, thereby enhancing the airflow convergence effect. Simultaneously, the tapering guide channel reduces airflow diffusion losses, making the airflow more concentrated, and ultimately resulting in efficient output through the nozzle.

[0017] In some embodiments, the guide channel is fan-shaped.

[0018] In some embodiments, the number of air guide holes is set to multiple, and the multiple air guide holes are spaced apart circumferentially along the boss.

[0019] In some embodiments, each of the guide channels corresponds to at least one of the air guide holes. Each guide channel corresponding to at least one air guide hole allows the airflow in the first air guide space to enter through the air guide hole and then diffuse or converge directionally along the fan-shaped structure of the guide channel. This one-to-one or one-to-many layout optimizes the airflow path, reduces turbulence, and improves the uniformity and efficiency of gas flow.

[0020] In some embodiments, the air guiding device further includes a sealing element, through which the first guide plate seals against the housing. The air guiding device also includes a sealing element, through which the first guide plate seals against the housing, to ensure that the airflow flows along a predetermined path and avoids leakage or turbulence interference.

[0021] In some embodiments, either the housing or the first guide plate is provided with a limiting groove, which extends circumferentially along the through hole in an annular shape. The sealing element is an annular seal, which is embedded in the limiting groove. This design secures the seal through the annular limiting groove, ensuring that the seal is not easily shifted or detached during assembly. Simultaneously, it allows the seal to deform uniformly circumferentially under pressure, ensuring a tight fit with the mating surface and preventing localized leakage. The structure of the annular seal embedded in the groove not only improves sealing reliability but also adapts to the groove design on either side of the housing or the guide plate, exhibiting high adaptability.

[0022] This application also provides a fixing structure, which includes:

[0023] support;

[0024] A positioning device is provided on one side of the bracket. The positioning device includes a guide rail, a slider slidably disposed on the guide rail, and a support assembly connected to the slider. The support assembly is used to abut against the electronic atomizing device to fix the electronic atomizing device between the bracket and the support assembly.

[0025] The aforementioned fixing structure achieves at least the following beneficial effects: It uses the cooperation of guide rails and sliders to achieve axial positioning of the electronic atomizing device, ensuring the device maintains a fixed posture during testing; the adjustable support components can accommodate electronic atomizing devices of different lengths, improving the equipment's versatility. This testing equipment is simple and reliable, meeting the positioning requirements during the testing of electronic atomizing devices.

[0026] In some embodiments, the support assembly includes a fixed base, an elastic element, and a support member. The fixed base is connected to the slider, the support member is disposed on the side of the fixed base near the bracket, the elastic element is connected between the fixed base and the support member, and the support member is used to abut against the end of the electronic atomizing device away from the air outlet.

[0027] In some embodiments, the fixed base has a guide hole, the support assembly further includes a support column, one end of the support column is connected to the support member, the other end of the support column is slidably disposed in the guide hole, the elastic member is sleeved on the support column, and the two ends of the elastic member elastically abut against the fixed base and the support member respectively.

[0028] In some embodiments, the positioning device further includes a snap-fit ​​assembly and a limiting member disposed on the bracket. The limiting member extends away from the bracket and is parallel to the guide rail. The limiting member has multiple slots along its length. The snap-fit ​​assembly is connected to the slider or the fixed base. One end of the snap-fit ​​assembly faces the limiting member and is configured to extend and retract relative to the slots to enter and exit any of the slots. When one end of the snap-fit ​​assembly is snapped into any of the slots, it can restrict the sliding of the slider on the guide rail.

[0029] In some embodiments, the snap-fit ​​assembly includes a pin, an operating member connected to the pin, a first magnetic member, and a second magnetic member with the same magnetism as the first magnetic member. The fixing base has a sliding hole, and the pin is slidably disposed in the sliding hole. The pin has a snap-fit ​​end and a transmission end that are far apart from each other. The snap-fit ​​end extends out of the sliding hole and faces the limiting member. The transmission end has a first magnetic member. The second magnetic member is disposed in the sliding hole and is disposed opposite to the first magnetic member. The second magnetic member can drive the snap-fit ​​end of the pin to automatically extend in a direction close to the slot under the magnetic force of the first magnetic member so as to snap into the slot. The operating member is configured to drive the pin to slide in the sliding hole in a direction that overcomes the magnetic force between the first magnetic member and the second magnetic member under the action of an external force so as to separate the snap-fit ​​end from the slot.

[0030] In some embodiments, the snap-fit ​​assembly includes a spring element, a push pin, and an operating element connected to the push pin. The fixed base has a sliding hole, and the push pin is slidably disposed in the sliding hole. The push pin has a snap-fit ​​end and a transmission end that are far apart from each other. The snap-fit ​​end extends out of the sliding hole and faces the limiting member. One end of the spring element elastically abuts against the transmission end, and the other end of the spring element elastically abuts against the wall of the sliding hole. The transmission end can drive the snap-fit ​​end of the push pin to automatically extend in a direction close to the slot under the elastic force of the spring element so as to snap into the slot. The operating element is configured to drive the push pin to slide in the sliding hole in a direction that overcomes the elastic force of the spring element under the action of an external force so as to separate the snap-fit ​​end from the slot.

[0031] In some embodiments, the limiting member has a guide ramp between any two adjacent slots along the direction close to the bracket. When the slider slides on the guide rail along the direction close to the bracket, the locking end can retract into the sliding hole under the abutment of the guide ramp to exit from one of the slots. Until the locking end crosses the guide ramp and aligns with another adjacent slot, the locking end can automatically extend to lock into the other adjacent slot.

[0032] In some embodiments, the limiting member has a guide ramp between any two adjacent slots along a direction away from the bracket. When the slider slides on the guide rail along a direction away from the bracket, the locking end can retract into the sliding hole under the abutment of the guide ramp to exit from one of the slots. Until the locking end crosses the guide ramp and aligns with another adjacent slot, the locking end can automatically extend to lock into the other adjacent slot.

[0033] In some embodiments, the support member has a support groove on one side near the bracket, the support groove being used to support the electronic atomizing device.

[0034] In some embodiments, the support member has two support surfaces arranged at an angle on the side near the bracket, and the two support surfaces enclose the support groove.

[0035] In some embodiments, the bracket is provided with an air supply channel and a mounting hole, and the detection device further includes a sealing cover that is sealed to the bracket. The sealing cover has a hollow interior forming a receiving cavity. The air supply channel communicates with the receiving cavity. The receiving cavity is used to accommodate the electronic atomizing device. The support assembly is used to abut against the end of the electronic atomizing device away from the air outlet so that the air outlet of the electronic atomizing device can be fixed to the mounting hole.

[0036] In some embodiments, the detection device further includes a flexible member disposed within the mounting hole, the flexible member having a vent hole adapted to the air outlet of the electronic atomizing device, the flexible member being able to seal the vent hole to the outer periphery of the location of the air outlet of the electronic atomizing device.

[0037] This application also provides a detection device, which includes a gas guiding device as described in any of the above embodiments and a fixing structure as described in any of the above embodiments. The fixing structure is used to fix the electronic atomizing device so that the gas outlet of the electronic atomizing device is connected to the through hole of the gas guiding device. The gas guiding device is disposed on the bracket and is used to guide the aerosol from the gas outlet of the electronic atomizing device to flow out.

[0038] The aforementioned testing equipment achieves at least the following beneficial effects: The fixed structure, through the cooperation of guide rails and sliders, achieves axial positioning of the electronic atomizing device, ensuring the device maintains a fixed posture during testing; the adjustable support components can adapt to electronic atomizing devices of different lengths, improving the equipment's versatility. This testing equipment is simple and reliable, meeting the positioning requirements during the testing of electronic atomizing devices. The gas guiding device uses nozzles set around the periphery of the through-hole, utilizing the gas introduced through the air inlet channel to form a directional airflow. Understandably, areas with higher flow rates have lower pressure; therefore, the negative pressure at these areas effectively guides the aerosol generated by the electronic atomizing device outwards and flows in a preset direction, preventing disorderly aerosol diffusion and ensuring the stability and consistency of aerosol transmission during testing. By adjusting the gas flow rate or pressure in the air inlet channel, the airflow velocity at the nozzles can be precisely controlled, thereby achieving dynamic regulation of the aerosol flow state, meeting different testing standards or research needs, and enhancing the equipment's application range and testing accuracy.

Detailed Implementation

[0057] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0058] Please see Figures 1 to 9 In some embodiments, this application provides a detection device 10, which includes a gas guiding device 100. Specifically, as shown in the example... Figure 5 and Figure 6 As shown, the air guiding device 100 is provided with an air inlet channel 114, a through hole 113, and a nozzle 140. The nozzle 140 is located around the through hole 113. The air inlet channel 114 communicates with the through hole 113 through the nozzle 140. The through hole 113 is used to communicate with the air outlet of the electronic atomizing device 20. The air inlet channel 114 can introduce gas and make the gas spray out from the nozzle 140 to guide the aerosol from the air outlet of the electronic atomizing device 20. The electronic atomizing device 20 can atomize an aerosol generating matrix to form an aerosol. The aerosol generating matrix can refer to a material that can be atomized under certain conditions to provide aerosol components.

[0059] The aforementioned testing device 10 can achieve at least the following beneficial effects: By setting nozzles 140 around the through-hole 113, the gas introduced by the air inlet channel 114 is ejected from the nozzles 140 to form a directional airflow. It is understood that the pressure is lower in areas with higher flow rates, and this negative pressure can effectively guide the aerosol generated by the electronic atomization device 20 to flow out and along a preset direction, avoiding disorderly diffusion of the aerosol and ensuring the stability and consistency of aerosol transmission during the test. By adjusting the gas flow rate or pressure of the air inlet channel 114, the airflow velocity of the nozzles 140 can be precisely controlled, thereby achieving dynamic regulation of the aerosol flow state, meeting different testing standards or research needs, and enhancing the application range and testing accuracy of the equipment.

[0060] like Figure 6 , Figure 7 and Figure 9As shown, in some embodiments, the air guiding device 100 includes a housing 110 and a flow guide 120. The housing 110 has a mounting groove 111, and a boss 112 is formed at the bottom of the mounting groove 111. The boss 112 has a through hole 113. The flow guide 120 is sealed and embedded in the mounting groove 111 and surrounds the groove wall of the mounting groove 111 to form an air guiding space 130. An air intake channel 114 is formed inside the housing 110 and communicates with the air guiding space 130. The flow guide 120 has an air passage 124 that communicates with the through hole 113. The hole wall of the air passage 124 and the outer peripheral surface of the boss 112 are spaced apart to form the nozzle 140. By designing the air guiding device 100 as a separate structure of housing 110 and flow guide 120, the flow guide 120 can be independently disassembled for easy cleaning or replacement, avoiding the impact of aerosol residue on test accuracy. The flow guide 120 can be fixed to the mounting groove 111 by a sealed embedding method, which ensures airtightness and simplifies the assembly process, such as snap-fit ​​or threaded connection, reducing manufacturing costs. The flow guide 120 is sealed and embedded in the mounting groove 111 of housing 110 and forms an air guiding space 130 with the groove wall of the mounting groove 111, so that the airflow of the air intake channel 114 is evenly distributed to the nozzle 140; at the same time, the air passage 124 of the flow guide 120 and the outer peripheral surface of the boss 112 form the nozzle 140, ensuring that the airflow is directionally ejected along the periphery of the through hole 113, effectively guiding the aerosol flow and avoiding turbulence interference.

[0061] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the air passage 124 is directly opposite the through hole 113. By aligning the air passage 124 of the guide member 120 with the through hole 113, the airflow can pass directly through the through hole 113 along a straight path, reducing energy loss and turbulence interference caused by airflow deflection and ensuring detection accuracy.

[0062] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, both the air passage 124 and the through hole 113 are circular holes and coaxially arranged. By designing both the air passage 124 and the through hole 113 as circular holes and arranging them coaxially, the airflow can flow axially, effectively reducing eddy currents and pressure drop losses, and improving the stability and uniformity of aerosol delivery. Simultaneously, the coaxial circular hole structure facilitates processing and assembly, ensuring the alignment accuracy between the guide member 120 and the housing 110. Furthermore, this design can optimize the airflow velocity distribution by adjusting the diameter ratio of the circular holes, allowing the aerosol to form a more concentrated flow path in the test area, further improving the repeatability and reliability of the test results.

[0063] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the inner cross-sectional profile of the vent 124 is larger than the outer cross-sectional profile of the boss 112. By making the inner cross-sectional profile of the vent 124 larger than the outer cross-sectional profile of the boss 112, a nozzle 140 structure is formed between the two.

[0064] like Figure 6 and Figure 10 As shown, in some embodiments, the flow guide 120 includes a first flow guide plate 121, a second flow guide plate 122, and a flow guide column 123. The first flow guide plate 121 and the flow guide plate are stacked along the thickness direction and connected by the flow guide column 123. The air passage 124 passes through the first flow guide plate 121, the flow guide column 123, and the second flow guide plate 122. The first flow guide plate 121 is sealed and covered by the mounting groove 111. The second flow guide plate 122 is embedded in the mounting groove 111 and divides the air guide space 130 into a first air guide space 131 and a second air guide space 132. The second flow guide plate 122 has an air guide hole 125. The first air guide space 131 communicates with the second air guide space 132 through the air guide hole 125. The first air guide space 131 communicates with the air intake channel 114, and the second air guide space 132 communicates with the nozzle 140. The flow guide 120 adopts a layered structure design, including a first flow guide plate 121 and a second flow guide plate 122 stacked together and connected and fixed by a flow guide column 123. An air passage 124 passes through the first flow guide plate 121, the flow guide column 123, and the second flow guide plate 122, forming a continuous airflow channel. The first flow guide plate 121 is sealed and capped at the top of the mounting groove 111, and the second flow guide plate 122 is embedded in the mounting groove 111, dividing the air guide space 130 into a first air guide space 131 and a second air guide space 132 that are interconnected. The first air guide space 131 is connected to the air inlet channel 114, and the second air guide space 132 receives airflow from the first air guide space 131 through the air guide hole 125 on the second flow guide plate 122 and guides it to the nozzle 140. This structure optimizes the airflow path through layered flow guidance and spatial separation, ensuring a smooth and uniform airflow transition, avoiding turbulence interference, and enhancing sealing and structural stability, making it suitable for high-precision pneumatic control systems.

[0065] like Figure 9As shown, in some embodiments, a guide portion 115 is formed at the bottom of the mounting groove 111. The guide portion 115 and the outer peripheral surface of the boss 112 enclose a guide groove 116. The second guide plate 122 covers the guide groove 116 and encloses it to form the second air guide space 132. The bottom of the mounting groove 111 is provided with a guide portion 115, which together with the outer peripheral surface of the boss 112 encloses the guide groove 116. The second guide plate 122 covers the guide groove 116 and cooperates with the guide groove 116 to enclose the second air guide space 132. This design guides the airflow along a predetermined path through the guide groove 116, so that the airflow is initially rectified before entering the second air guide space 132, further reducing turbulence interference. The second air guide space 132 is connected to the first air guide space 131 through the air guide hole 125, and finally smoothly delivers the airflow to the nozzle 140. This structure optimizes the uniformity of airflow distribution and enhances the flow guidance efficiency, making it suitable for aerosol transport or precision gas control scenarios where high airflow stability is required.

[0066] like Figure 9 As shown, in some embodiments, the number of guide sections 115 is set to multiple, and the multiple guide sections 115 are arranged at intervals along the circumference of the boss 112 on the outer periphery of the boss 112. A guide groove 116 is formed between any two adjacent guide sections 115. The number of nozzles 140 is set to multiple, and the multiple nozzles 140 are arranged at intervals along the circumference of the through hole 113. The guide grooves 116 correspond one-to-one with the nozzles 140. The multiple guide sections 115 are evenly spaced along the circumference of the boss 112, and independent guide grooves 116 are formed between adjacent guide sections 115. This annular array design can realize multi-channel flow diversion of airflow, avoid flow overload of a single path, and improve the symmetry and uniformity of gas distribution. The number of nozzles 140 corresponds one-to-one with the guide grooves 116 and is equidistantly distributed along the circumference of the through hole 113, ensuring that the airflow of each guide groove 116 is independently guided to the matching nozzle 140. The multi-nozzle 140 structure design surrounding the through hole 113 forms an annular air curtain by introducing directional airflow through the air intake channel 114. This effectively guides the aerosol generated by the electronic atomizing device 20 to flow in a preset direction, avoiding disordered diffusion of aerosols and ensuring the stability and consistency of aerosol transmission during the test.

[0067] like Figure 9As shown, in some embodiments, the guide channel 116 gradually tapers towards the protrusion 112. This can be considered as the cross-sectional area of ​​the guide channel 116 or the second air guide space 132 gradually decreasing towards the protrusion 112 (i.e., a tapering design). This tapering structure accelerates airflow and creates a local low-pressure zone at the end of the guide channel 116 through the Venturi effect, thereby enhancing the airflow convergence effect. Simultaneously, the tapering guide channel 116 reduces airflow diffusion losses, making the airflow more concentrated, and ultimately resulting in efficient output through the nozzle 140.

[0068] like Figure 9 As shown, in some embodiments, the guide channel 116 is fan-shaped.

[0069] like Figure 9 As shown, in some embodiments, the number of air guide holes 125 is set to a plurality, and the plurality of air guide holes 125 are arranged at circumferential intervals along the boss 112.

[0070] like Figure 6 As shown, in some embodiments, each of the guide channels 116 corresponds to at least one of the air guide holes 125. Each guide channel 116 corresponds to at least one air guide hole 125, allowing the airflow in the first air guide space 131 to enter through the air guide hole 125 and then diffuse or converge directionally along the fan-shaped structure of the guide channel 116. This one-to-one or one-to-many layout optimizes the airflow path, reduces turbulence, and improves the uniformity and efficiency of gas flow.

[0071] like Figure 5 , Figure 6 and Figure 11 As shown, in some embodiments, the air guiding device 100 further includes a sealing element 150, through which the first guide plate 121 is sealed against the housing 110. The air guiding device 100 further includes a sealing element 150, through which the first guide plate 121 is sealed against the housing 110, to ensure that the airflow flows along a predetermined path and avoids leakage or turbulence interference.

[0072] like Figure 5 , Figure 6 and Figure 11As shown, in some embodiments, either the housing 110 or the first guide plate 121 is provided with a limiting groove 126. The limiting groove 126 extends circumferentially along the through hole 113 and is annular. The sealing element 150 is an annular sealing element 150, which is embedded in the limiting groove 126. This design fixes the sealing element 150 through the annular limiting groove 126, ensuring that the sealing element 150 is not easily displaced or detached during assembly. At the same time, it allows the sealing element 150 to deform uniformly circumferentially under pressure, tightly fitting with the mating surface and avoiding local leakage. The structure of the annular sealing element 150 embedded in the groove not only improves the sealing reliability but also adapts to the groove design on either side of the housing 110 or the guide plate, exhibiting high adaptability.

[0073] like Figure 2 , Figure 3 , Figure 12 and Figure 13As shown, in some embodiments, the detection device 10 further includes a sealing cover 200 and a fixing structure. The fixing structure includes a positioning device 500 and a bracket 300. The bracket 300 is provided with an air supply channel 310 and a mounting hole 320. The bracket 300 has two opposing sides along the axial direction of the mounting hole 320. The air guiding device 100 is connected to one side of the bracket 300, and the through hole 113 communicates with the mounting hole 320. The sealing cover 200 is sealed and connected to the other side of the bracket 300. The sealing cover 200 has a hollow interior forming a receiving cavity 210. The air supply channel 310 communicates with the receiving cavity 210. The receiving cavity 210 is used to house the electronic atomizing device 20, and the air outlet of the electronic atomizing device 20 can communicate with the through hole 113 through the mounting hole 320. The sealing cover 200 and the bracket 300 cooperate to form a closed receiving cavity 210, ensuring that the electronic atomizing device 20 is in a sealed environment during the detection process, avoiding external interference. The gas supply channel 310 provides the required gas to the receiving cavity 210. For example, the gas supply channel 310 can be connected to an external air pump to pump gas into the receiving cavity 210, creating positive pressure within it. The receiving cavity 210 can be connected to the air inlet of the electronic atomizing device 20. The airflow enters the electronic atomizing device 20 from the air inlet and then flows out from the air outlet. The electronic atomizing device 20 atomizes the aerosol generation matrix to form an aerosol. The airflow carries the formed aerosol out of the air outlet of the electronic atomizing device 20. Simultaneously, the air outlet of the electronic atomizing device 20 is connected to the through hole 113 of the gas guiding device 100 through the mounting hole 320, achieving effective connection of the gas path and ensuring the accuracy and reliability of the detection data. This design not only improves the sealing and stability of the detection but also facilitates the installation and positioning of the electronic atomizing device 20, making it suitable for detection scenarios with high airtightness requirements. The positioning device 500 is located on the side of the bracket 300 facing away from the air guiding device 100 and inside the sealing cover 200. The positioning device 500 includes a guide rail 510, a slider 520 slidably mounted on the guide rail 510, and a support assembly 530 connected to the slider 520. The support assembly 530 abuts against the end of the electronic atomizing device 20 away from the air outlet to fix the electronic atomizing device 20 between the bracket 300 and the support assembly 530. Through the cooperation of the guide rail 510 and the slider 520, the positioning device 500 allows the support assembly 530 to move axially, thereby accommodating electronic atomizing devices 20 of different lengths and ensuring that their air outlets are accurately aligned with the mounting hole 320 and the through hole 113 of the air guiding device 100. The abutting action of the support assembly 530 stably fixes the electronic atomizing device 20, preventing it from shifting or loosening during testing, and improving the stability and repeatability of the test. In addition, this structure facilitates quick adjustment and positioning, making it suitable for testing products of various specifications and improving testing efficiency and compatibility.

[0074] like Figure 5 , Figure 6 and Figure 11 As shown, in some embodiments, the detection device 10 further includes a flexible member 400 disposed within the mounting hole 320. The flexible member 400 has a vent hole 410 adapted to the air outlet of the electronic atomizing device 20. The flexible member 400 can be sealed to the outer periphery of the air outlet of the electronic atomizing device 20 via the vent hole 410. The flexible member 400 can be made of an elastic material, allowing it to tightly fit the outer periphery of the air outlet of the electronic atomizing device 20, ensuring airtightness and preventing gas leakage. The design of the flexible member 400 not only facilitates the installation and disassembly of the electronic atomizing device 20 but also adapts to air outlets of different sizes or shapes, improving the versatility of the detection device 10. Simultaneously, the alignment of the vent hole 410 of the flexible member 400 with the air outlet of the electronic atomizing device 20 ensures unobstructed airflow, making gas flow more stable during detection, thereby improving detection accuracy and reliability. This structure is particularly suitable for testing scenarios that require frequent replacement of different models of electronic atomizing devices 20, taking into account both sealing and ease of operation.

[0075] like Figure 12 and Figure 13 As shown, in some embodiments, the support assembly 530 includes a fixed base 531, an elastic element 532, and a support element 533. The fixed base 531 is connected to the slider 520. The support element 533 is located on the side of the fixed base 531 near the bracket 300. The elastic element 532 is connected between the fixed base 531 and the support element 533. The support element 533 is used to abut against the end of the electronic atomizing device 20 away from the air outlet. Through the buffering effect of the elastic element 532, the support assembly 530 can adapt to electronic atomizing devices 20 of different lengths, providing a flexible abutment force and avoiding damage or positioning deviation caused by rigid contact. The connection between the fixed base 531 and the slider 520 ensures that the support assembly 530 can slide and adjust along the guide rail 510, while the compression deformation of the elastic element 532 (such as a spring or silicone buffer pad) can absorb assembly tolerances, ensuring that the air outlet of the electronic atomizing device 20 is always tightly connected with the air guiding device 100. This structure ensures stability during the testing process and improves the equipment's compatibility with products of different specifications, making it suitable for efficient and high-precision automated testing processes.

[0076] like Figure 14As shown, in some embodiments, the fixed base 531 has a guide hole 5311, and the support assembly 530 also includes a support column 534. One end of the support column 534 is connected to the support member 533, and the other end of the support column 534 is slidably disposed in the guide hole 5311. The elastic member 532 is sleeved on the support column 534, and both ends of the elastic member 532 elastically abut against the fixed base 531 and the support member 533, respectively. This structure provides axial guidance for the abutting movement of the support member 533 through the sliding engagement of the support column 534 and the guide hole 5311, ensuring that the electronic atomizing device 20 maintains linear displacement under pressure, avoiding skewness or jamming, and improving positioning accuracy. The elastic member 532 (such as a compression spring) is sleeved on the support column 534, and its two ends abut against the fixed base 531 and the support member 533, respectively, forming a stable elastic buffer system. The elastic abutting force is evenly distributed, avoiding local stress concentration, and maintaining the stability of the device during the detection process.

[0077] like Figure 13 As shown, in some embodiments, the support member 533 has a support groove 5331 on the side near the bracket 300, and the support groove 5331 is used to support the electronic atomizing device 20. The support member 533 has a support groove 5331 on the side near the bracket 300, and the support groove 5331 is used to support the electronic atomizing device 20. The design of this support groove 5331 can more stably support the end of the electronic atomizing device 20, preventing it from shifting or shaking during testing, thereby improving the accuracy and consistency of the test. The shape of the support groove 5331 can match the end contour of the electronic atomizing device 20, ensuring that the device maintains the correct posture during testing and avoiding airtightness test errors due to tilting. Anti-slip pads or soft materials can be added inside the groove, which protects the device shell and prevents slippage through frictional resistance, making it particularly suitable for the vibration environment of high-speed automated production lines. The size of the support groove 5331 can be designed to be adjustable or modular to adapt to electronic atomizing devices 20 of different diameters or shapes, reducing changeover and adjustment time.

[0078] like Figure 14As shown, in some embodiments, the support member 533 has two support surfaces 5332 arranged at an included angle on the side near the bracket 300, and the two support surfaces 5332 enclose the support groove 5331. This support groove 5331 forms a stable support space through the included angle structure of the two support surfaces 5332, which can better adapt to the outer contour of the electronic atomizing device 20 and provide multi-directional limiting function. This design ensures the positioning accuracy of the device during the testing process, and the natural guidance formed by the included angle facilitates the quick placement and removal of the device. The included angle of the two support surfaces 5332 can adapt to the shape characteristics of electronic atomizing devices 20 of different specifications; it can be set as a fixed angle for standardized support, or designed as an adjustable angle mechanism to meet the compatibility requirements of multiple product specifications. This structure ensures support stability while also providing ease of operation and process adaptability.

[0079] like Figure 12 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the positioning device 500 further includes a snap-fit ​​assembly 540 and a limiting member 550 disposed on the bracket 300. The limiting member 550 extends in a direction away from the bracket 300 and is parallel to the guide rail 510. The limiting member 550 has a plurality of slots 551 along its own length. The snap-fit ​​assembly 540 is connected to the slider 520 or the fixing base 531. One end of the snap-fit ​​assembly 540 faces the limiting member 550 and is configured to extend and retract relative to the slots 551 to enter and exit any of the slots 551. When one end of the snap-fit ​​assembly 540 is snapped into any of the slots 551, it can restrict the sliding of the slider 520 on the guide rail 510. This structure achieves precise multi-position positioning of the slider 520 on the guide rail 510 through the cooperation of the limiting component 550 and the locking assembly 540. The spacing of the slots 551 can be set to equidistant or non-equidistant distribution according to testing requirements, allowing the slider 520 to quickly lock in different testing positions. The locking assembly 540 can adopt a spring-loaded telescopic pin structure, and the locking state can be switched by manual pressing or electromagnetic drive, ensuring positioning reliability while taking into account ease of operation. The parallel arrangement of the limiting component 550 and the guide rail 510 ensures that the positioning force direction is consistent with the movement direction of the slider 520, avoiding lateral force interference and improving sliding stability. The setting of multiple slots 551 allows for flexible adjustment of the position of the support component 533 according to the length of different models of electronic atomizing devices 20, giving the positioning device 500 good versatility and expandability.

[0080] like Figure 15As shown, in some embodiments, the snap-fit ​​assembly 540 includes a pin 543, an operating member 544 connected to the pin 543, a first magnetic member 541, and a second magnetic member 542 with the same magnetism as the first magnetic member 541. The fixing base 531 is provided with a sliding hole 5312, and the pin 543 is slidably disposed in the sliding hole 5312. The pin 543 has a snap-fit ​​end 5431 and a transmission end 5432 that are far apart from each other. The snap-fit ​​end 5431 extends out of the sliding hole 5312 and faces the limiting member 550. The transmission end 5432 is provided with the first magnetic member 541. The second magnetic element 542 is disposed in the sliding hole 5312 and is disposed opposite to the first magnetic element 541. The second magnetic element 542 can drive the snap pin 543's snap-fit ​​end 5431 to automatically extend in the direction close to the slot 551 under the magnetic force of the first magnetic element 541 so as to snap into the slot 551. The operating element 544 is configured to drive the snap pin 543 to slide in the sliding hole 5312 in the direction of overcoming the magnetic force between the first magnetic element 541 and the second magnetic element 542 under the action of external force so as to separate the snap-fit ​​end 5431 from the slot 551. This structure utilizes the repulsive force between like-pole magnets to achieve an automatic locking function. When the slider 520 moves to the target position, the ejector pin 543 automatically locks into the slot 551 under the action of magnetic force to complete the positioning. The magnetic force can ensure that the locking is stable and reliable. During operation, simply move the operating part 544 to overcome the magnetic force and make the ejector pin 543 exit the slot 551 to unlock. This structure is compact and easy to operate, and is suitable for detection equipment 10 that requires frequent position adjustment.

[0081] In other embodiments, the snap-fit ​​assembly 540 includes a spring element, a push pin 543, and an operating element 544 connected to the push pin 543. The fixing base 531 is provided with a sliding hole 5312, and the push pin 543 is slidably disposed in the sliding hole 5312. The push pin 543 has a snap-fit ​​end 5431 and a transmission end 5432 that are spaced apart from each other. The snap-fit ​​end 5431 extends out of the sliding hole 5312 and faces the limiting member 550. One end of the spring element elastically abuts against the transmission end 5432. The other end of the elastic member elastically abuts against the wall of the sliding hole 5312. The transmission end 5432 can drive the snap-fit ​​end 5431 of the ejector pin 543 to automatically extend in a direction close to the slot 551 under the elastic force of the elastic member so as to snap into the slot 551. The operating member 544 is configured to drive the ejector pin 543 to slide in the sliding hole 5312 in a direction that overcomes the elastic force of the elastic member under the action of external force so as to separate the snap-fit ​​end 5431 from the slot 551. The elastic element provides a continuous rebound force, ensuring that the ejector pin 543 always maintains a tendency to move towards the slot 551. When the slider 520 moves to the target position, the ejector pin 543 automatically engages with the slot 551 under the action of the elastic force to achieve positioning. During operation, simply move the operating element 544 to overcome the elastic force to retract the ejector pin 543 and unlock it. This design is simple and reliable. The elastic coefficient of the elastic element can be selected according to the actual load requirements to ensure that the locking force is moderate. At the same time, the mating surface between the ejector pin 543 and the slot 551 can be designed as a bevel structure to reduce the operating force during unlocking.

[0082] like Figure 15As shown, in some embodiments, the limiting member 550 has a guide slope 552 between any two adjacent slots 551 along the direction close to the bracket 300. When the slider 520 slides on the guide rail 510 along the direction close to the bracket 300, the locking end 5431 has a tendency to retract into the sliding hole 5312 under the abutment of the guide slope 552 to exit from one of the slots 551. Until the locking end 5431 crosses the guide slope 552 and aligns with another adjacent slot 551, the locking end 5431 can automatically extend to lock into the other adjacent slot 551. The guide ramp 552 structure enables the slider 520 to automatically unlock and relock during unidirectional movement. When the slider 520 is pushed towards the bracket 300, the locking end 5431 of the ejector pin 543 is forced to retract under the squeezing action of the guide ramp 552. After passing the ramp, it automatically pops out and locks into the next slot 551 under the action of the elastic element or magnetic force, thus realizing continuous positioning adjustment without manual operation. This design is particularly suitable for occasions that require progressive adjustment. The operator only needs to apply force in one direction to complete the switching of multiple positions, which greatly improves the adjustment efficiency. At the same time, the tilt angle of the guide ramp 552 is optimized to ensure that the ejector pin 543 transitions smoothly without jamming. In addition, this structure reduces the complexity of operation while ensuring positioning accuracy, and is suitable for testing equipment 10 or precision instruments that require rapid multi-position adjustment.

[0083] In other embodiments, the limiting member 550 has a guide slope 552 between any two adjacent slots 551 along a direction away from the bracket 300. When the slider 520 slides on the guide rail 510 along a direction away from the bracket 300, the locking end 5431 has a tendency to retract into the sliding hole 5312 under the abutment of the guide slope 552 to exit from one of the slots 551. Until the locking end 5431 crosses the guide slope 552 and aligns with another adjacent slot 551, the locking end 5431 can automatically extend to lock into another adjacent slot 551. By setting a reverse guide ramp 552, the slider 520 achieves automatic unlocking and relocking when moving away from the support 300. When the slider 520 is pulled outward, the locking end 5431 of the ejector pin 543 is forced to retract under the squeezing action of the guide ramp 552. After passing the ramp, it automatically pops out and locks into the next slot 551 under the action of the elastic element or magnetism, thus achieving a mechanical self-locking effect for unidirectional continuous adjustment. This design is particularly suitable for occasions that require rapid adjustment away from the support or gradual outward positioning. The operator only needs to apply force in one direction to complete the switching of multiple gears, which greatly improves the adjustment efficiency.
