Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to a detection device. Background Technology

[0002] In the field of electronic atomization devices, performance testing of the atomizer core is a crucial step in the research and development and production process.

[0003] However, traditional solutions lack dedicated fixtures for testing the performance of atomizing cores.

[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 detection device to address the above problems.

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

[0007] A supply module is provided, having an installation slot for embedding an atomizing core capable of atomizing an aerosol generating matrix to form an aerosol. The supply module also includes a liquid supply channel for conveying the aerosol generating matrix, which communicates with the installation slot and supplies the aerosol generating matrix to the atomizing core.

[0008] A pressure control module is connected to the supply module and is capable of adjusting the pressure in the liquid supply channel to control the supply speed of the aerosol generating matrix to the atomizing core.

[0009] The aforementioned testing equipment can achieve at least the following beneficial effects: integrating functions such as atomizing core installation and aerosol generation matrix supply into a single integrated supply module significantly simplifies the testing operation process; the installation slot of the supply module can accommodate atomizing cores of various specifications, effectively reducing the specialization of testing fixtures and improving equipment versatility; and through the pressure control module, the pressure in the supply channel can be precisely adjusted to achieve precise control of the aerosol generation matrix supply speed, thereby adapting to rapid switching between different testing conditions, meeting diverse testing needs, and greatly improving testing efficiency.

[0010] In some embodiments, the supply module further includes a liquid storage tank connected to one end of the liquid supply channel. The other end of the liquid supply channel penetrates the surface of the supply module to form an injection port for injecting the aerosol generating matrix. The detection device also includes an injection plug detachably and sealingly connected to the injection port. A pressure regulating channel is formed within the pressure control module, connected to the liquid storage tank to adjust the pressure within the tank. The detachable structure of the injection plug facilitates rapid replenishment of the aerosol generating matrix. The direct connection between the pressure regulating channel and the liquid storage tank enables closed-loop control of the supply pressure, improving the controllability and repeatability of the testing process, effectively preventing liquid leakage, and reducing external piping connections. This makes the device structure more compact and easier to operate, particularly suitable for experimental scenarios requiring frequent changes of test liquids or comparisons of multiple operating conditions.

[0011] In some embodiments, the supply module also includes an exhaust channel, one end of which is connected to the liquid storage tank, and the other end of which penetrates the surface of the supply module to form an exhaust port. The testing device also includes an exhaust plug, which is detachably and sealingly connected to the exhaust port. This design, with the exhaust channel connecting the liquid storage tank and the exhaust port within the supply module and the detachable exhaust plug, allows the existing gas in the liquid storage tank to be smoothly discharged through the exhaust channel when aerosol is injected through the injection port to generate the matrix. After injection, the double seal of the injection plug and the exhaust plug quickly establishes a sealed liquid storage environment, enabling the pressure control module to precisely regulate the pressure in the liquid storage tank, significantly improving the efficiency and reliability of the test preparation stage.

[0012] In some embodiments, the detection device further includes a sealing cap, with the liquid storage tank extending through the supply module to form a sealing opening, and the sealing cap detachably sealing the sealing opening. By extending the liquid storage tank to the surface of the supply module to form a sealing opening and sealing it with a sealing cap, this design retains the airtightness of the liquid storage tank while providing a convenient channel for direct contact with the liquid storage tank. This allows users to quickly complete the cleaning and maintenance of the liquid storage tank or the replacement of large-volume liquids. At the same time, the detachable nature of the sealing cap, together with the injection port and the vent port, forms multiple sealing guarantees, significantly improving equipment maintenance efficiency while ensuring the accuracy of system pressure regulation. It is particularly suitable for experimental environments that require regular cleaning or replacement of aerosol generation matrices with different properties. This structure, while maintaining the integrity of the original injection and venting functions, further optimizes the operability and maintenance convenience of the equipment through modular design.

[0013] In some embodiments, the supply module further includes a transfer channel. One end of the transfer channel has a through-hole communicating with the storage tank, and the through-hole is located above the liquid surface of the aerosol generating matrix within the storage tank. The other end of the transfer channel is connected to the pressure regulating channel. The supply module also includes a transfer channel, one end of which is connected to the storage tank via a through-hole located above the liquid surface of the aerosol generating matrix within the storage tank, and the other end is connected to the pressure regulating channel. This structural design allows the pressure regulating module to directly act on the gas phase space within the storage tank, achieving precise control of the internal gas pressure of the storage tank while ensuring gas-liquid isolation.

[0014] In some embodiments, the pressure regulating channel includes a first channel and a second channel. One end of the first channel is connected to one end of the second channel, and the other end of the first channel penetrates the surface of the pressure control module to form a vent. The vent is connected to the transition channel. The other end of the second channel penetrates the surface of the pressure control module to form a liquid inlet / outlet. Both the liquid inlet and the vent are higher than the junction of the first and second channels in the height direction. The pressure regulating channel adopts a structure similar to a U-shaped tube connector. This structure forms a natural gas-liquid isolation barrier through the liquid seal principle. It allows gas in the first channel to freely enter the liquid storage tank through the vent and through-hole for pressure transmission, while the high-positioned liquid inlet prevents accidental liquid overflow, ensuring the stability and reliability of the pressure regulation process. This design simplifies the system structure while achieving physical isolation between pressure transmission and liquid delivery, making it particularly suitable for aerosol generation systems that require long-term stable operation and high pressure control accuracy.

[0015] In some embodiments, the detection device further includes a seal that is sealingly connected to the connection between the transfer channel and the air port. The addition of a seal at the connection between the transfer channel and the air port achieves an airtight connection through elastic deformation, ensuring a complete seal of the pressure transmission channel, eliminating the risk of gas leakage, and guaranteeing pressure regulation accuracy.

[0016] In some embodiments, the pressure control module further includes a pressure detection port communicating with the first channel, and the detection device includes a pressure sensor disposed within the pressure detection port. By opening a pressure detection port on the first channel and embedding a pressure sensor, real-time monitoring of the internal pressure of the liquid storage tank is achieved. The pressure sensor is directly embedded in the detection port using miniaturized packaging technology, and its sensing end face is in direct contact with the gas in the channel, achieving accurate pressure feedback.

[0017] In some embodiments, the supply module also includes an air supply channel that is not connected to the liquid supply channel. This air supply channel is located around the periphery of the mounting groove and can eject gas to carry away the aerosol generated at the atomizing core. The supply module employs a dual-channel independent design, with a dedicated air supply channel for aerosol transport added next to the liquid supply channel. This air supply channel is located around the periphery of the mounting groove and is physically isolated from the liquid supply channel. Precisely controlled airflow guides the flow of the aerosol generated at the atomizing core.

[0018] In some embodiments, the number of air supply channels is set to multiple, and the multiple air supply channels are spaced apart along the periphery of the mounting groove. The multiple air supply channels are arranged in a ring around the periphery of the mounting groove and can spray to form an enveloping air curtain to guide the flow of aerosol generated at the atomizing core.

[0019] In some embodiments, the pressure control module is detachably connected to the side of the supply module facing away from the mounting groove. The pressure control module has an air supply chamber and an air inlet communicating with the air supply chamber. The air inlet is used to connect to an air pump to adjust the air pressure within the air supply chamber, thereby controlling the air supply speed of the air supply channel. The pressure control module adopts a modular and detachable design, and is fixed to the supply module by detachable connections such as magnetic attraction, snap-fit, or threads. The pressure control module has a precision-machined air supply chamber, which is connected to an external air pump via the air inlet to form an air path. When the air pump is working, the system can dynamically adjust the air pressure parameters within the air supply chamber, thereby controlling the airflow speed of the air supply channel.

[0020] In some embodiments, the detection device further includes a sealing seat, through which the atomizing core is embedded in the mounting groove. The sealing seat seals against the groove wall and the atomizing core. The sealing seat may be made of an elastic sealing material, with its outer edge forming an interference fit with the groove wall and its inner wall tightly covering the outer surface of the atomizing core, thereby creating a double-sealing structure between the groove wall and the atomizing core. This design not only achieves airtight isolation to prevent gas leakage but also protects the atomizing core from mechanical vibration through elastic buffering, ensuring the stability and reliability of aerosol delivery during detection. The detachable design of the sealing seat also facilitates regular maintenance and replacement, extending the equipment's service life.

[0021] In some embodiments, the detection device further includes a positioning bracket detachably connected to the supply module. The positioning bracket has a positioning groove for fixing electrodes electrically connected to the atomizing core. The positioning bracket can be fixed to the supply module via a detachable connection method such as magnetic attraction, snap-fit, or threaded connection. The positioning bracket has a precision-machined positioning groove for reliably fixing the electrodes electrically connected to the atomizing core. This positioning bracket can be made of insulating material, effectively preventing short-circuit risks while achieving precise electrode positioning, thus improving the safety and reliability of the equipment operation.

[0022] In some embodiments, the positioning bracket, the supply module, and the pressure control module are stacked sequentially from top to bottom. The testing device includes a first magnetic chuck, a second magnetic chuck, and a third magnetic chuck. The first magnetic chuck is located on the positioning bracket, the second magnetic chuck is located on the supply module, and the third magnetic chuck is located on the pressure control module. The positioning bracket and the supply module are magnetically engaged via the first and second magnetic chucks, and the supply module and the pressure control module are magnetically engaged via the second and third magnetic chucks. The testing device adopts a modular, stacked magnetic connection structure. The positioning bracket, supply module, and pressure control module are arranged sequentially from top to bottom and quickly assembled using magnetic components. The positioning bracket has a first magnetic chuck, the supply module has a second magnetic chuck, and the pressure control module has a third magnetic chuck that matches the supply module. The magnetic engagement of the first and second magnetic chucks connects the positioning bracket and the supply module, while the magnetic engagement of the second and third magnetic chucks connects the supply module and the pressure control module. This magnetic connection system employs a polarity-matching design, enabling not only automatic and precise alignment and stable adsorption between modules, but also preventing reverse installation. Its non-rigid connection effectively buffers mechanical vibration, while the quick-release design between modules significantly improves the ease of equipment maintenance. Furthermore, the magnetic mating surfaces can be sealed to ensure airtightness between modules while maintaining airflow connectivity, thereby ensuring the stable operation of the detection system.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0038] Please see Figures 1 to 7 In some embodiments, this application provides a testing device 10, which includes a supply module 100 and a pressure control module 200. Specifically, as shown in the figure... Figure 5 As shown, the supply module 100 has a mounting slot 110, which is used to embed an atomizing core 20 capable of atomizing an aerosol generating matrix to form an aerosol. Figure 6 and Figure 7 As shown, the supply module 100 has a liquid supply channel 120 for conveying the aerosol generating matrix. The liquid supply channel 120 is connected to the mounting groove 110 and is used to supply the aerosol generating matrix to the atomizing core 20. The pressure control module 200 is connected to the supply module 100 and can adjust the pressure in the liquid supply channel 120 to control the supply speed of the aerosol generating matrix to the atomizing core 20. The aerosol generating matrix can refer to a material that can be atomized under certain conditions to provide aerosol components.

[0039] The aforementioned testing equipment 10 can achieve at least the following beneficial effects: integrating the functions of atomizing core 20 installation and aerosol generation matrix supply delivery into an integrated supply module 100 significantly simplifies the testing operation process; the installation slot 110 of the supply module 100 can accommodate atomizing cores 20 of various specifications, effectively reducing the specialization of testing fixtures and improving equipment versatility; and through the pressure control module 200, the pressure in the supply channel 120 is precisely adjusted to achieve precise control of the aerosol generation matrix supply speed, thereby adapting to rapid switching of different testing conditions, meeting diverse testing needs, and greatly improving testing efficiency.

[0040] like Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the supply module 100 further includes a liquid storage tank, which is connected to one end of the liquid supply channel 120. The other end of the liquid supply channel 120 penetrates the surface of the supply module 100 to form an injection port 121 for injecting the aerosol generation matrix. The detection device 10 also includes an injection plug 410, which is detachably and sealingly connected to the injection port 121. The pressure control module 200 includes a pressure regulating channel 210, which is connected to the liquid storage tank to adjust the pressure within the tank. The detachable structure of the injection plug 410 facilitates rapid replenishment of the aerosol generation matrix. The direct connection between the pressure regulating channel 210 and the liquid storage tank enables closed-loop control of the supply pressure, which not only improves the controllability and repeatability of the testing process but also effectively prevents liquid leakage. Furthermore, it reduces external pipeline connections, making the device structure more compact and easier to operate, making it particularly suitable for experimental scenarios requiring frequent changes of test liquids or comparisons of multiple operating conditions.

[0041] like Figure 8 and Figure 9 As shown, in some embodiments, the supply module 100 also forms an exhaust channel 140. One end of the exhaust channel 140 is connected to the liquid storage tank, and the other end of the exhaust channel 140 penetrates the surface of the supply module 100 to form an exhaust port 141. The detection device 10 also includes an exhaust plug 420, which is detachably and sealingly connected to the exhaust port 141. The addition of an exhaust channel 140 connecting the liquid storage tank and the exhaust port 141, along with the detachable exhaust plug 420, allows the existing gas in the liquid storage tank to be smoothly discharged through the exhaust channel 140 when aerosol is injected through the injection port 121 to generate the matrix. After injection, the double seal of the injection plug 410 and the exhaust plug 420 quickly establishes a sealed liquid storage environment, enabling the pressure control module 200 to precisely regulate the pressure of the liquid storage tank, significantly improving the efficiency and reliability of the test preparation stage.

[0042] like Figure 7 , Figure 8 and Figure 11As shown, in some embodiments, the detection device 10 further includes a sealing cover 430. The liquid storage tank extends through the supply module 100 to form a sealing port 131, and the sealing cover 430 is detachably disposed at the sealing port 131. By extending the liquid storage tank to the surface of the supply module 100 to form a sealing port 131 and being closed by the sealing cover 430, this design retains the airtightness of the liquid storage tank while providing a convenient channel for direct contact with the liquid storage tank. This allows users to quickly complete the cleaning and maintenance of the liquid storage tank or the replacement of large-capacity liquids. At the same time, the detachable nature of the sealing cover 430, together with the injection port 121 and the vent port 141, forms multiple sealing guarantees, which greatly improves the equipment maintenance efficiency while ensuring the accuracy of system pressure regulation. It is particularly suitable for experimental environments that require regular cleaning or replacement of aerosol generation matrices with different properties. While maintaining the integrity of the original liquid injection and venting functions, this structure further optimizes the operability and maintenance convenience of the equipment through modular design.

This structural design allows the pressure regulating module to directly act on the gas phase space within the storage tank, achieving precise control of the internal gas pressure of the storage tank while ensuring gas-liquid isolation.

[0044] like Figure 9As shown, in some embodiments, the pressure regulating channel 210 includes a first channel 211 and a second channel 212. One end of the first channel 211 is connected to one end of the second channel 212. The other end of the first channel 211 penetrates the surface of the pressure control module 200 to form a vent 213, which is connected to the transition channel 150. The other end of the second channel 212 penetrates the surface of the pressure control module 200 to form a liquid inlet 214 for liquid to enter and exit. Both the liquid inlet 214 and the vent 213 are higher than the junction of the first channel 211 and the second channel 212 in the height direction. The pressure regulating channel 210 adopts a structure design similar to a U-shaped tube connector. This structure forms a natural gas-liquid isolation barrier through the liquid seal principle. It allows gas in the first channel 211 to freely enter the liquid storage tank through the vent 213 and the through hole 151 for pressure transmission. At the same time, the high-positioned liquid inlet 214 prevents accidental liquid overflow, ensuring the stability and reliability of the pressure regulating process. This design simplifies the system structure while achieving physical isolation between pressure transmission and liquid delivery, making it particularly suitable for aerosol generation systems that require long-term stable operation and high pressure control accuracy.

[0045] like Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, the detection device 10 further includes a sealing element 440 that is sealingly connected to the connection between the transition channel 150 and the air port 213. The detection device 10 adds a sealing element 440 at the connection between the transition channel 150 and the air port 213. This sealing element 440 achieves an airtight connection through elastic deformation, ensuring a complete seal of the pressure transmission channel, eliminating the risk of gas leakage, and guaranteeing pressure regulation accuracy.

By opening a pressure detection port 220 on the first channel 211 and embedding the pressure sensor 450 therein, real-time monitoring of the internal pressure of the liquid storage tank is achieved. The pressure sensor 450 is directly embedded in the detection port using miniaturized packaging technology, and its sensing end face is in direct contact with the gas in the channel, achieving accurate pressure feedback.

[0047] like Figure 5 and Figure 6As shown, in some embodiments, the supply module 100 also has an air supply channel 160 that is not connected to the liquid supply channel 120. The air supply channel 160 is located at the periphery of the mounting groove 110 and can spray gas to carry away the aerosol generated at the atomizing core 20. The supply module 100 adopts a dual-channel independent design, with a dedicated air supply channel 160 for aerosol delivery added next to the liquid supply channel 120. The air supply channel 160 is located at the periphery of the mounting groove 110 and is physically isolated from the liquid supply channel 120. The flow of aerosol generated at the atomizing core 20 is guided by precisely controlled airflow.

[0048] like Figure 5 As shown, in some embodiments, the number of air supply channels 160 is set to multiple, and the multiple air supply channels 160 are arranged at intervals along the periphery of the mounting groove 110. The multiple air supply channels 160 are arranged in a ring along the periphery of the mounting groove 110 and can spray to form an enveloping air curtain to guide the flow of aerosol generated at the atomizing core 20.

[0049] like Figure 6 and Figure 7 As shown, in some embodiments, the pressure control module 200 is detachably connected to the side of the supply module 100 facing away from the mounting groove 110. The pressure control module 200 has an air supply chamber 230 and an air inlet 240 communicating with the air supply chamber 230. The air inlet 240 is used to connect to an air pump to adjust the air pressure in the air supply chamber 230, thereby controlling the air supply speed of the air supply channel 160. The pressure control module 200 adopts a modular and detachable design, and is fixed to the supply module 100 by detachable connection methods such as magnetic attraction, snap-fit, or threads. The pressure control module 200 has a precision-machined air supply chamber 230, which is connected to an external air pump through the air inlet 240 to form an air path. When the air pump is working, the system can dynamically adjust the air pressure parameters in the air supply chamber 230, thereby controlling the airflow speed of the air supply channel 160.

[0050] like Figure 7 and Figure 8As shown, in some embodiments, the detection device 10 further includes a sealing seat 460, through which the atomizing core 20 is embedded in the mounting groove 110. The sealing seat 460 seals against the groove wall of the mounting groove 110 and the atomizing core 20. The sealing seat 460 may be made of an elastic sealing material, with its outer edge forming an interference fit with the groove wall of the mounting groove 110, and its inner wall tightly covering the outer surface of the atomizing core 20, thereby constructing a double sealing structure between the groove wall of the mounting groove 110 and the atomizing core 20. This design not only achieves airtight isolation to prevent gas leakage, but also protects the atomizing core 20 from mechanical vibration through elastic buffering, ensuring the stability and reliability of aerosol delivery during detection. The detachable design of the sealing seat 460 also facilitates regular maintenance and replacement, extending the service life of the equipment.

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the detection device 10 further includes a positioning bracket 300 detachably connected to the supply module 100.
