Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to an atomization product extraction device. Background Technology

[0002] In the fields of tobacco toxicology research and aerosol analysis, Cambridge filters are widely used to collect aerosols generated during tobacco combustion or atomization.

[0003] However, traditional extraction methods typically require immersing the filter in an organic solvent and then performing multiple steps such as shaking, centrifugation, and filtration to obtain the sample. This method is not only cumbersome and time-consuming, but also the organic solvent at high concentrations may introduce additional toxicity, affecting the accuracy of the experimental results.

[0004] The information disclosed above in the background art of this application is only used to understand the background of the concept of this application, and may contain information that does not constitute prior art. Summary of the Invention

[0005] Therefore, it is necessary to provide an atomized product extraction device to address the above problems.

[0006] This application provides an atomized product extraction device, which includes:

[0007] A collection tube, one end of which has an operating port, and the other end of which has a collection port for collecting atomized products, the collection tube being used to hold a filter; and

[0008] An extrusion assembly, which extends at least partially into the collection tube from the operating port and is capable of extruding atomized products from the filter.

[0009] The above-mentioned atomized product extraction device can achieve at least the following beneficial effects:

[0010] The structural design of the collection tube, which includes both an operating port and a collection port, allows the filter to be inserted into the collection tube through the operating port. The tubular structure of the collection tube provides a stable space for the filter, ensuring that it remains positioned during the extrusion process. The extendable design of the extrusion component allows it to act directly on the filter, achieving the extraction of atomized products from within the filter. The collection port ensures that the extruded atomized products are collected in a directional manner. The overall structure improves extraction efficiency and sample integrity while maintaining ease of operation.

[0011] In some embodiments, the collection tube includes a tube body and a cap, the cap being positioned over the end of the collection tube furthest from the operating port, and the cap having the collection port. By configuring the collection tube as a separate structure of tube body and cap, the cap can be positioned over the end of the tube body furthest from the operating port, and the collection port is provided on the cap, facilitating cleaning and maintenance of the collection tube and sealing cap, while the sealing effect of the cap ensures that the atomized product can only flow out directionally from the collection port during extrusion, preventing sample leakage.

[0012] In some embodiments, the tube is at least partially transparent. By making the tube at least partially transparent, the operator can observe the position of the filter within the collection tube and the squeezing process and effect of the squeezing assembly on the filter, thereby adjusting the squeezing force and position in real time to ensure that the atomized product is fully squeezed out and flows to the collection port. This also avoids problems such as filter breakage or incomplete squeezing caused by blind operation, improving the reliability and efficiency of the extraction process.

[0013] In some embodiments, the tube is transparent. By making the tube transparent, operators can more easily and intuitively observe the position of the filter in the collection tube and the squeezing process and effect of the squeezing component on the filter. This allows for real-time adjustment of the squeezing force and position, ensuring that the atomized product is fully squeezed out and flows to the collection port. It also avoids problems such as filter breakage or incomplete squeezing caused by blind operation, thus improving the reliability and efficiency of the extraction process.

[0014] In some embodiments, the tube body is either a glass tube or a plastic tube. Glass tubes possess excellent chemical stability, corrosion resistance, and transparency, ensuring that the collection tube does not undergo chemical reactions or contamination when in contact with different atomized products. They also facilitate observation of the filter's condition and the operation of the extrusion assembly, thereby improving the reliability and ease of operation of the atomized product collection. Plastic tubes offer advantages in terms of lightweight, impact resistance, and cost, reducing the overall weight of the collection tube and improving its durability. They are also easy to mass-produce and replace, making them suitable for cost-sensitive or frequently operated experimental environments, ensuring stable and efficient extrusion of the filter by the extrusion assembly.

[0015] In some embodiments, the collection tube further includes a first sealing ring, which seals against the wall between the cover and the tube body. By setting the first sealing ring to seal against the wall between the cover and the tube body, leakage of the atomized product from the connection between the cover and the tube body during extrusion can be effectively prevented. This ensures that the extrusion operation of the extrusion assembly on the filter is fully applied to the extrusion of the atomized product, while preventing external contaminants from entering the collection tube. This guarantees the purity of the collected atomized product and improves the sealing performance and operational reliability of the collection tube.

[0016] In some embodiments, the atomized product extraction device further includes a filter element with filter holes communicating with the collection port. The filter element supports the filter sheet, and the extrusion assembly presses the filter sheet against the filter element to squeeze out the atomized product within the filter sheet and allow it to flow through the filter holes to the collection port. By providing a filter element with filter holes and communicating with the collection port, the filter element can stably support the filter sheet while providing a reliable extrusion support surface for the extrusion assembly. When the extrusion assembly presses the filter sheet against the filter element, the atomized product can be efficiently squeezed out and flow directionally through the filter holes to the collection port, preventing atomized product residue or dispersion loss.

[0017] In some embodiments, the filter element includes a filter plate and a support portion connected to the filter plate. The support portion abuts against the cover. The filter plate has filter holes, and the filter plate and the cover are spaced apart. By designing the filter element as a combined structure including a filter plate and a support portion, with the support portion abutting against the cover, the filter element can be securely installed in the collection tube, preventing shaking or displacement during extrusion. The spaced-apart arrangement between the filter plate and the cover creates a certain space, allowing the atomized product extruded from the filter to flow smoothly through the filter holes into this space and ultimately be guided to the collection port. This structural design not only optimizes the flow path of the atomized product and reduces residue but also avoids flow obstruction or blockage caused by direct contact between the filter plate and the cover, thereby improving the collection efficiency and operational reliability of the atomized product extraction device.

[0018] In some embodiments, multiple filter holes are provided, and these holes are evenly distributed. By providing multiple and evenly distributed filter holes, the filtration and flow guiding performance of the filter plate can be optimized. Multiple evenly distributed filter holes increase the flow area of ​​the atomized product, reduce flow resistance, and allow the atomized product to flow quickly and evenly through the filter holes to the collection port when the extrusion assembly extrudes the filter, avoiding local blockage or pressure concentration. Simultaneously, the evenly distributed filter hole structure ensures that the filter is subjected to balanced force during extrusion, preventing filter breakage or atomized product residue due to stress concentration, thereby improving the collection efficiency and operational stability of the atomized product extraction device.

[0019] In some embodiments, the extrusion assembly includes a push rod and a piston. The piston is disposed inside the collection tube and seals against the tube wall. One end of the push rod is connected to the piston, and the other end extends out of the operating port for operation, driving the piston to slide within the collection tube and extrude the filter. By designing the extrusion assembly as a combination of a push rod and a piston, with the piston sealing against the tube wall, an effective sealing space is ensured during extrusion, preventing leakage or backflow of atomized products and improving collection efficiency. One end of the push rod is connected to the piston, and the other end extends out of the operating port, facilitating user application of force to smoothly slide the piston within the collection tube, thereby uniformly extruding the filter and fully releasing the atomized products to flow towards the collection port. This structural design not only enhances the convenience and controllability of operation but also optimizes the stability and sealing of the extrusion process, ensuring efficient and complete collection of atomized products, thus improving the overall performance and user experience of the atomized product extraction device.

[0020] In some embodiments, the extrusion assembly further includes a second sealing ring, which is fitted onto the outer circumferential surface of the piston and seals against the wall of the collection tube. By adding a second sealing ring to the outer circumferential surface of the piston, a more reliable sealing contact is formed with the wall of the collection tube, effectively preventing leakage of the atomized product from the gap between the piston and the tube wall during extrusion, ensuring that the atomized product is completely extruded and flows to the collection port. The second sealing ring enhances the sealing performance between the piston and the collection tube, further improving the sealing performance and operational stability of the atomized product extraction device.

[0021] In some embodiments, multiple second sealing rings are provided, spaced apart axially along the collecting tube. By providing multiple second sealing rings and arranging them axially spaced along the collecting tube, a multi-layer sealing structure can be formed, further enhancing the sealing effect between the piston and the collecting tube. It is understood that even if one sealing ring experiences slight wear or failure due to prolonged use, the remaining sealing rings can still maintain good sealing performance, ensuring that the atomized product does not leak or flow back from the gap between the piston and the tube wall, significantly improving the sealing stability of the atomized product extraction device.

[0022] In some embodiments, the outer contour of the second sealing ring's cross-section is larger than the inner contour of the collecting tube's cross-section. By designing the outer contour of the second sealing ring to be larger than the inner contour of the collecting tube's cross-section, the sealing ring can form an interference fit with the inner wall of the collecting tube after installation, thereby generating a pre-tightening force and further enhancing the sealing effect. This structural design ensures that the sealing ring fits tightly against the tube wall, effectively preventing leakage or backflow of atomized products from the gap between the piston and the tube wall during extrusion, thus improving sealing reliability. Simultaneously, the interference fit can compensate for wear caused by manufacturing tolerances or long-term use, maintaining stable sealing performance.

[0023] In some embodiments, the outer profile of the piston's cross-section is smaller than the inner profile of the collection tube's cross-section.

[0024] In some embodiments, the inner profile of the cross-section of the collecting tube is larger than the outer profile of the cross-section of the filter element. By designing the inner profile of the cross-section of the collecting tube to be larger than the outer profile of the cross-section of the filter element, the filter element can be easily inserted into or removed from the collecting tube, facilitating installation, replacement, or cleaning of the filter element and improving ease of use.

[0025] In some embodiments, the atomized product extraction device further includes a connector that is detachably connected to the collection port. The connector and collection port are detachably connected, such as by a threaded connection, facilitating quick installation or replacement, simplifying the operation process, and ensuring a tight seal at the connection to prevent leakage of the atomized product. Furthermore, this design facilitates cleaning and maintenance, preventing residue accumulation from affecting the extraction effect and improving the hygiene and long-term reliability of the device. This structure optimizes the ease of operation and maintenance of the atomized product extraction device.

[0026] In some embodiments, the atomized product extraction device further includes a support, with the end of the collection tube furthest from the operating port fixed to the support, and the support not obstructing the collection port. By setting up a support and fixing the end of the collection tube furthest from the operating port to the support, such as by threading the cover and the support with screws or other fasteners, the stability of the device can be improved, preventing the collection tube from shaking or tilting during operation, and ensuring the smooth collection and extraction of the atomized product. Simultaneously, the design of the support not obstructing the collection port ensures unobstructed flow, avoiding interference with the outflow of the atomized product or the connection of subsequent processing equipment. Furthermore, the support structure facilitates the placement and fixation of the device, making it suitable for different working environments, such as laboratory benchtops, improving operational convenience and safety.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention 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 thorough understanding of the present invention. However, the present invention can be practiced 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, this application provides an atomized product extraction device 10, which includes a collection tube 100 and a squeezing assembly 200. One end of the collection tube 100 is provided with an operation port 111, and the other end of the collection tube 100 is provided with a collection port 121 for collecting atomized products. The collection tube 100 is used to place a filter. The squeezing assembly 200 extends at least partially into the collection tube 100 from the operation port 111 and is capable of squeezing out the atomized products in the filter.

[0035] The above-mentioned atomized product extraction device 10 can achieve at least the following beneficial effects:

[0036] The structural design of the collection tube 100 with the operation port 111 and the collection port 121 allows the filter to be inserted into the collection tube 100 through the operation port 111. The tubular structure of the collection tube 100 provides a stable space for the filter, ensuring that the filter remains in position during the extrusion process. The extendable design of the extrusion component 200 allows it to act directly on the filter, realizing the extrusion extraction of the atomized products inside the filter. The setting of the collection port 121 ensures that the extruded atomized products can be collected in a directional manner. The overall structure improves extraction efficiency and sample integrity while maintaining ease of operation.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments, the collection tube 100 includes a tube body 110 and a cap 120. The cap 120 covers the end of the collection tube 100 away from the operating port 111, and the cap 120 has the collection port 121. By setting the collection tube 100 as a separate structure of tube body 110 and cap 120, the cap 120 can cover the end of tube body 110 away from the operating port 111, and the collection port 121 is provided on the cap 120. This facilitates the cleaning and maintenance of the collection tube 100 and the sealing cap, while the sealing effect of the cap 120 ensures that the atomized product can only flow out directionally from the collection port 121 during the extrusion process, preventing sample leakage.

[0038] like Figure 2 As shown, in some embodiments, the tube 110 is at least partially transparent. By making the tube 110 at least partially transparent, the operator can observe the position of the filter in the collection tube 100 and the squeezing process and effect of the squeezing assembly 200 on the filter, thereby adjusting the squeezing force and position in real time to ensure that the atomized product is fully squeezed out and flows to the collection port 121. At the same time, it avoids problems such as filter damage or incomplete squeezing caused by blind operation, thus improving the reliability and efficiency of the extraction process.

[0039] like Figure 2 As shown, in some embodiments, the tube 110 is a transparent tube 110. By making the tube 110 transparent, the operator can more conveniently and intuitively observe the position of the filter in the collection tube 100 and the squeezing process and effect of the squeezing component 200 on the filter, thereby adjusting the squeezing force and position in real time to ensure that the atomized product is fully squeezed out and flows to the collection port 121. At the same time, it avoids problems such as filter damage or incomplete squeezing caused by blind operation, thus improving the reliability and efficiency of the extraction process.

[0040] In some embodiments, the tube 110 is either a glass tube or a plastic tube. Glass tubes possess excellent chemical stability, corrosion resistance, and transparency, ensuring that the collection tube 100 does not undergo chemical reactions or contamination when in contact with different atomized products. They also facilitate observation of the filter's condition and the operation of the extrusion assembly 200, thereby improving the reliability and ease of operation of atomized product collection. Plastic tubes offer advantages in terms of lightweight, impact resistance, and cost, reducing the overall weight of the collection tube 100 and improving its durability. They are also easy to mass-produce and replace, making them suitable for cost-sensitive or frequently operated experimental environments, ensuring stable and efficient extrusion of the filter by the extrusion assembly 200.

[0041] like Figure 2 and Figure 3 As shown, in some embodiments, the collection tube 100 further includes a first sealing ring 131, which seals against the wall between the cover 120 and the tube body 110. By setting the first sealing ring 131 to seal against the wall between the cover 120 and the tube body 110, leakage of the atomized product from the connection between the cover 120 and the tube body 110 during the extrusion process can be effectively prevented. This ensures that the extrusion operation of the extrusion assembly 200 on the filter is fully applied to the extrusion of the atomized product, while preventing external contaminants from entering the collection tube 100. This ensures the collection purity of the atomized product and improves the sealing performance and operational reliability of the collection tube 100.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, the atomized product extraction device 10 further includes a filter element 300 with filter holes 311 communicating with the collection port 121. The filter element 300 supports the filter sheet, and the extrusion assembly 200 presses the filter sheet against the filter element 300 to squeeze out the atomized product within the filter sheet and allow it to flow through the filter holes 311 to the collection port 121. By providing a filter element 300 with filter holes 311 and communicating with the collection port 121, the filter element 300 can stably support the filter sheet while providing a reliable extrusion support surface for the extrusion assembly 200. When the extrusion assembly 200 presses the filter sheet against the filter element 300, the atomized product can be efficiently squeezed out and flow directionally through the filter holes 311 to the collection port 121, preventing atomized product residue or dispersion loss.

[0043] like Figure 3As shown, in some embodiments, the filter element 300 includes a filter plate 310 and a support portion 320 connected to the filter plate 310. The support portion 320 abuts against the cover 120. The filter plate 310 has filter holes 311. The filter plate 310 and the cover 120 are spaced apart. By designing the filter element 300 as a combined structure including the filter plate 310 and the support portion 320, with the support portion 320 abutting against the cover 120, the filter element 300 can be securely installed in the collection tube 100, preventing shaking or displacement during extrusion. The filter plate 310 and the cover 120 are spaced apart, forming a certain space, allowing the atomized products extruded from the filter to flow smoothly through the filter holes 311 into this space, and finally be guided to the collection port 121. This structural design not only optimizes the flow path of the atomized product and reduces residue, but also avoids flow obstruction or blockage caused by direct contact between the filter plate 310 and the cover 120, thereby improving the collection efficiency and operational reliability of the atomized product extraction device 10.

[0044] like Figure 2 As shown, in some embodiments, multiple filter holes 311 are provided, and the multiple filter holes 311 are evenly distributed. By setting multiple and evenly distributed filter holes 311, the filtration and flow guiding performance of the filter plate 310 can be optimized. The pore diameter of the filter hole 311 can be 0.5 mm, and the distance between any two adjacent filter holes 311 can be 2 mm. This is only an example and is not intended to imply that this is the only possible arrangement. Multiple evenly distributed filter holes 311 can increase the flow area of ​​the atomized product and reduce flow resistance, allowing the atomized product to flow quickly and evenly through the filter holes 311 to the collection port 121 when the extrusion assembly 200 extrudes the filter plate, avoiding local blockage or pressure concentration. Simultaneously, the evenly distributed filter hole structure ensures that the filter plate is subjected to balanced force during extrusion, preventing filter plate damage or atomized product residue due to stress concentration, thereby improving the collection efficiency and operational stability of the atomized product extraction device 10.

[0045] like Figure 2 and Figure 3As shown, in some embodiments, the extrusion assembly 200 includes a push rod 210 and a piston 220. The piston 220 is disposed inside the collection tube 100 and seals against the wall of the collection tube 100. One end of the push rod 210 is connected to the piston 220, and the other end of the push rod 210 extends outside the operation port 111 for operation, driving the piston 220 to slide within the collection tube 100 and extrude the filter. By designing the extrusion assembly 200 as a combination of the push rod 210 and the piston 220, with the piston 220 sealing against the wall of the collection tube 100, an effective sealing space can be formed during extrusion, preventing leakage or backflow of atomized products and improving collection efficiency. One end of the push rod 210 is connected to the piston 220, and the other end extends outside the operation port 111, facilitating user operation and driving the piston 220 to slide smoothly within the collection tube 100, thereby uniformly extruding the filter and allowing the atomized products to be fully released and flow to the collection port 121. This structural design not only enhances the ease and controllability of operation, but also optimizes the stability and sealing of the extrusion process, ensuring that the atomized products can be collected efficiently and completely, thereby improving the overall performance and user experience of the atomized product extraction device 10.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, the extrusion assembly 200 further includes a second sealing ring 232, which is fitted onto the outer circumferential surface of the piston 220 and seals against the wall of the collection tube 100. By adding a second sealing ring 232 to the outer circumferential surface of the piston 220, a more reliable sealing contact is formed with the wall of the collection tube 100, effectively preventing leakage of the atomized product from the gap between the piston 220 and the tube wall during extrusion, ensuring that the atomized product is completely extruded and flows to the collection port 121. The second sealing ring 232 enhances the sealing performance between the piston 220 and the collection tube 100, further improving the sealing performance and operational stability of the atomized product extraction device 10.

[0047] like Figure 2 and Figure 3As shown, in some embodiments, the number of second sealing rings 232 is set to multiple, and the multiple second sealing rings 232 are arranged axially spaced along the collection tube 100. By setting multiple second sealing rings 232 and arranging them axially spaced along the collection tube 100, a multi-layer sealing structure can be formed, further enhancing the sealing effect between the piston 220 and the collection tube 100. It is understood that even if one sealing ring experiences slight wear or failure due to long-term use, the remaining sealing rings can still maintain good sealing performance, ensuring that the atomized product does not leak or flow back from the gap between the piston 220 and the tube wall, significantly improving the sealing stability of the atomized product extraction device 10.

[0048] In some embodiments, the outer contour of the cross-section of the second sealing ring 232 is larger than the inner contour of the cross-section of the collecting tube 100. By designing the outer contour of the cross-section of the second sealing ring 232 to be larger than the inner contour of the cross-section of the collecting tube 100, the sealing ring can form an interference fit with the inner wall of the collecting tube 100 after installation, thereby generating a pre-tightening force and further enhancing the sealing effect. This structural design ensures that the sealing ring fits tightly against the tube wall, effectively preventing leakage or backflow of atomized products from the gap between the piston 220 and the tube wall during extrusion, thus improving sealing reliability. At the same time, the interference fit can also compensate for wear caused by manufacturing tolerances or long-term use, maintaining stable sealing performance.

[0049] In some embodiments, the outer profile of the cross-section of the piston 220 is smaller than the inner profile of the cross-section of the collecting tube 100.

[0050] In some embodiments, the inner profile of the cross-section of the collection tube 100 is larger than the outer profile of the cross-section of the filter element. By designing the inner profile of the cross-section of the collection tube 100 to be larger than the outer profile of the cross-section of the filter element, the filter element can be easily inserted into or removed from the collection tube 100, facilitating the installation, replacement, or cleaning of the filter element and improving ease of use.

[0051] For example, the inner contour of the cross-section of the collecting tube 100 is circular with an inner diameter of 46 mm; the filter plate is adapted to the shape of the collecting tube 100 and has a diameter of 45 mm; the outer contour of the cross-section of the piston 220 is circular with a diameter of 45.8 mm; and the diameter of the second sealing ring 232 is 2 mm. This is merely an example and is not intended to indicate or imply that this is the only possible scenario.

[0052] In some embodiments, the atomized product extraction device 10 further includes a connector that is detachably connected to the collection port 121. The connector and collection port 121 are detachably connected, such as by a threaded connection, facilitating quick installation or replacement of the connector, simplifying the operation process, and ensuring a tight seal at the connection to prevent leakage of the atomized product. Furthermore, this design facilitates cleaning and maintenance, preventing residue accumulation from affecting the extraction effect and improving the hygiene and long-term reliability of the device. This structure optimizes the ease of operation and maintenance of the atomized product extraction device 10.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the atomized product extraction device 10 further includes a support 400, with the end of the collection tube 100 away from the operating port 111 fixed to the support 400, and the support 400 not obstructing the collection port 121. By setting the support 400 and fixing the end of the collection tube 100 away from the operating port 111 to the support 400, such as by threading the cover 120 to the support 400 with screws or other fasteners, the stability of the device can be improved, preventing the collection tube 100 from shaking or tilting during operation, and ensuring the smooth collection and extraction of the atomized product. At the same time, the design of the support 400 not obstructing the collection port 121 ensures that the collection port 121 is unobstructed, avoiding interference with the outflow of the atomized product or the connection of subsequent processing equipment. Furthermore, the structure of the support 400 facilitates the placement and fixation of the device, making it suitable for different working environments, such as laboratory benchtops, improving the convenience and safety of operation.
