Description

Technical Field

[0001] This utility model relates to the field of solid phase extraction technology and belongs to a solid phase extraction device for electronic atomizing liquid. Background Technology

[0002] Electronic cigarettes use batteries to power resistance wires, generating heat that evaporates the e-liquid into vapor, producing a sensation similar to smoking. E-liquid is a complex mixture containing various chemical components. Solid-phase extraction (SPE) selectively separates and extracts specific components based on the differences in their interactions with the solid-phase extraction material. For example, SPE can separate polar and non-polar components in e-liquid, or separate different types of flavorings and additives, allowing for individual study and analysis of each component. Based on liquid-solid chromatography, SPE employs selective adsorption and elution to enrich, separate, and purify samples. It is a physical extraction process involving both liquid and solid phases and can be approximated as a simple chromatographic process. A common method involves passing the liquid sample solution through an adsorbent to retain the analyte, then rinsing away impurities with a solvent of appropriate strength, followed by rapid elution with a small amount of solvent, achieving rapid separation, purification, and concentration. It can also selectively adsorb interfering impurities, allowing the analyte to flow out; or it can simultaneously adsorb impurities and the analyte, and then use a suitable solvent to selectively elute the analyte.

[0003] For example, the solid phase extraction device with prior art publication number CN221385297U can simultaneously install a test tube rack and a waste liquid collection box. This eliminates the need to replace the collection container with a test tube rack during the detection process, thereby simplifying the experimental steps and effectively improving the detection efficiency.

[0004] However, the existing technology described above still has the following problems in use: multiple extraction columns placed together can easily cause confusion, and operators may easily miss or repeatedly place samples, which will reduce the solid phase extraction efficiency. Based on this, the present invention provides a solid phase extraction device for electronic atomized liquids that is easy to distinguish and has high solid phase extraction efficiency. Utility Model Content

[0005] Therefore, this utility model provides a solid phase extraction device for electronic atomized liquids to solve the problem in the prior art that the placement of several extraction columns together can easily cause confusion, resulting in missed or repeated sample placement and reduced solid phase extraction efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A solid-phase extraction device for electronic atomizing liquid includes an extraction chamber with an extraction tray inside. The top of the extraction tray has multiple equally spaced placement holes, each containing an extraction column. A top plate is provided above the extraction tray, and the top of the top plate has the same number of perforations as the placement holes. Each perforation is hinged to a cover plate. The extraction tray is connected to the extraction chamber via a lifting mechanism. A collection assembly is provided below the extraction tray, including a test tube rack and a waste liquid tank.

[0008] Furthermore, connecting plates are fixedly provided on both sides of the bottom of the top plate, and connecting slots are provided on both sides of the top of the extraction tray. The connecting plates are inserted into the connecting slots and fixed to the extraction tray by fastening bolts. When the operator loosens the fastening bolts, the top plate can be removed from the extraction tray for inspection and replacement.

[0009] Furthermore, the lifting mechanism includes two linear modules, and mounting grooves are provided on the inner walls of both the front and rear sides of the extraction box. The two linear modules are fixed in the two mounting grooves respectively, and the sliders of the two linear modules are fixed to the extraction tray.

[0010] Furthermore, the test tube rack holds multiple test tubes, and openings are provided on both sides of the extraction box. The test tube rack and waste liquid tank extend into the openings, making it convenient for staff to quickly pull the test tube rack and waste liquid tank to move.

[0011] Furthermore, sliders are fixedly provided on both sides of the test tube rack and the waste liquid tank, and grooves communicating with the openings are opened on the inner walls of the front and rear sides of the extraction tank. The grooves are located below the linear module, and the sliders are slidably disposed in the grooves. The sliders limit the movement of the test tube rack and the waste liquid tank by limiting their position on the side walls, thereby improving the stability of their movement.

[0012] Furthermore, two spring pins are fixedly inserted through the front end of the extraction box. Slots are machined on the surface of the slider at the front end of the test tube rack and the surface of the slider at the front end of the waste liquid tank. The pins of the spring pins are inserted into the slots to fix the sliders by means of the spring pins, which can improve the stability of the sliders and eliminate the need for staff to manually fix the test tube rack and waste liquid tank all the time, making it more labor-saving to use.

[0013] Furthermore, the top of the extraction chamber is hinged to a top cover, which is locked to the extraction chamber by a lock to improve the firmness between the top cover and the extraction chamber.

[0014] Furthermore, the extraction chamber, top cover, and slider are all made of transparent acrylic sheets, which allows staff to easily view the inside of the extraction chamber at any time.

[0015] This utility model has the following advantages:

[0016] 1. This utility model provides a top plate above the extraction tray, with multiple cover plates on the top plate corresponding to multiple extraction columns. When the cover plate is perforated, it can seal the extraction column, preventing impurities from falling into the extraction column and affecting the extraction effect. Furthermore, when using the extraction column, the cover plate can be closed to help the staff quickly distinguish whether the extraction column is in use, thus avoiding the reuse of the extraction column and reducing the workload of the staff.

[0017] 2. The extraction tray is automatically raised and lowered by a linear module. During activation, sample loading, and rinsing operations, the extraction column is driven down into the waste liquid tank by the linear module, which can prevent liquid from splashing out. During elution, the extraction column is lowered to be close to the test tube, which can also prevent leakage.

[0018] 3. The position of the test tube rack or waste liquid tank can be adjusted by pulling, which can improve the solid phase extraction efficiency. Sliding blocks are set on the side walls of the test tube rack and waste liquid tank. The sliding of the sliding blocks in the trough can improve the movement stability of the two.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Refer to the instruction manual appendix Figures 1-5 This utility model provides a solid-phase extraction device for electronic atomizing liquid, including an extraction box 1. The top of the extraction box 1 is hinged to a top cover 14, which is locked to the extraction box 1 by a lock. An extraction tray 2 is provided inside the extraction box 1. The top of the extraction tray 2 is machined with a plurality of equally spaced placement holes 3. An extraction column 4 is placed inside each placement hole 3. A top plate 5 is provided above the extraction tray 2. The top of the top plate 5 has the same number of perforations 6 as the placement holes 3. The top of each perforation 6 is hinged to a cover plate 7. The extraction tray 2 is connected to the extraction box 1 by a lifting mechanism 8. A collection component 9 is provided below the extraction tray 2. The collection component 9 includes a test tube rack 91 and a waste liquid tank 92. A plurality of test tubes are placed on the test tube rack 91.

[0031] Connecting plates 10 are fixed on both sides of the bottom of the top plate 5. Connecting slots 11 are opened on both sides of the top of the extraction tray 2. The connecting plates 10 are inserted into the connecting slots 11 and fixed to the extraction tray 2 by fastening bolts 12. Afterwards, the staff can loosen the fastening bolts 12 to remove the top plate 5 from the extraction tray 2 for inspection and replacement.

[0032] The extraction chamber 1 has openings 13 on both sides. The test tube rack 91 and the waste liquid tank 92 extend into the openings 13. The test tube rack 91 and the waste liquid tank 92 are fixedly equipped with sliders 93 on both sides. The inner walls of the front and rear sides of the extraction chamber 1 are provided with grooves 94 that communicate with the openings 13. The grooves 94 are located below the linear module 81. The sliders 93 are slidably disposed in the grooves 94. The sliders 93 limit the movement of the test tube rack 91 and the waste liquid tank 92 by limiting their movement on the side walls, thereby improving the stability of their movement.

[0033] Extraction chamber 1, top cover 14 and slider 93 are all made of transparent acrylic sheet. The transparent acrylic sheet has high transparency and high strength, which makes it easy for staff to check the inside of extraction chamber 1 at any time during solid phase extraction.

[0034] In actual use, first, pull the waste liquid tank 92 to move it under the extraction tray 2, then open the top cover 14, and open one or more covers 7 as needed. Next, inject activation liquid into the extraction column 4 on the extraction tray 2 to remove impurities from the extraction column 4. The impurities fall from the bottom of the extraction column 4 into the waste liquid tank 92, completing the activation operation. Then, inject the dissolved electronic atomized liquid sample into the extraction column 4. The packing material in the extraction column 4 adsorbs and retains the components to be analyzed in the electronic atomized liquid, while the remaining components fall from the extraction column 4 into the waste liquid tank 92, completing the sample loading operation. Afterwards, continue... Eluent is injected into the extraction column 4 to remove interfering substances from the sample. The eluent and interfering substances then fall from the bottom of the extraction column 4 into the waste liquid tank 92, thus completing the rinsing operation. Finally, the test tube rack 91 is moved back into the extraction chamber 1 and placed below the extraction column 4. Elution solution is then injected into the extraction column 4. A small volume of eluent is sufficient to elute the analyte adsorbed in the extraction column 4 and inject it into the test tube placed on the test tube rack 91, thus completing the elution operation. Then, the staff pulls the test tube rack 91 to remove it.

[0035] Refer to the instruction manual appendix Figures 1-5 The extraction box 1 has two spring pins 95 fixedly inserted at the front end. The surface of the slider 93 at the front end of the test tube rack 91 and the surface of the slider 93 at the front end of the waste liquid tank 92 are both machined with slots 96. The pins of the spring pins 95 are inserted into the slots 96. By using the spring pins 95 to fix the slider 93, the stability of the slider 93 can be improved. The staff does not need to manually fix the test tube rack 91 and the waste liquid tank 92 all the time, which makes it more labor-saving to use.

[0036] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
