Description

Technical Field

[0001] This utility model relates to the field of solid phase extraction technology, and in particular to an auxiliary experimental tool for a solid phase extraction device. Background Technology

[0002] The core component of a solid-phase extraction (SPE) apparatus is the SPE column, which typically consists of a column filled with a solid adsorbent. In order to maintain the normal flow of the liquid, auxiliary experimental tools are one of the essential tools in the experiment.

[0003] A search revealed that CN221131074U discloses a booster device for a solid-phase extraction column, comprising an extraction column with a discharge pipe connected to its bottom end. An air-propulsion device is inserted into the top of the extraction column, comprising an air bladder and a sterilization box. An air inlet is located at the top of the air bladder, and the sterilization box is positioned above the air inlet. In practical operation, the user inserts one end of the air-propulsion device into the extraction column. Squeezing the air bladder forces the internal gas into the extraction column, thereby expelling the substance from the column. Because the air inlet at the top of the air bladder is connected to the sterilization box, external air first enters the sterilization box, is sterilized by an ultraviolet germicidal lamp, and then enters the extraction column through the air bladder. This prevents dust and bacteria from entering the extraction column, improving safety.

[0004] The aforementioned comparative documents contain an internal filter screen to filter the air entering the disinfection box. However, due to the limited space at the air inlet, the filter screen is often fixed in the required position by adhesive. This makes it inconvenient and time-consuming to replace the filter screen. Therefore, it is necessary to provide an auxiliary experimental tool for solid phase extraction devices to quickly and easily install and remove the filter screen, thereby improving the efficiency of filter screen replacement. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary experimental tool for a solid phase extraction device, in order to solve the problem mentioned in the background art. In the aforementioned prior art, the internal filter screen is provided to filter the air entering the disinfection box. However, due to the limited space at the air inlet, the filter screen is often fixed in the required position by pasting. This makes it inconvenient to replace the filter screen and the replacement work is time-consuming and laborious.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an auxiliary experimental tool for a solid-phase extraction apparatus, comprising:

[0008] A booster assembly, comprising a booster body, a disinfection box, and an air inlet; the disinfection box is located on top of the booster body, and the air inlet is fixed inside one side of the disinfection box.

[0009] The assembly / disassembly component includes a filter screen, a threaded post, a connecting frame, a connecting plate, and a limiting post. The filter screen is located inside the air inlet, the threaded post is threadedly connected to the inside of the filter screen, the connecting frame is fixed to the outer surface of the threaded post, the connecting plate is fixed to the outer surfaces of both ends of the air inlet, the limiting post is fixed to the outer surface of the connecting frame, and the limiting post is connected through the inside of the connecting plate.

[0010] Furthermore, a limiting rod is connected through the limiting post and the connecting plate, and a guide plate is fixed on the outer surface of the limiting rod.

[0011] Furthermore, a spring is fixed to the outer surface of the bottom end of the guide plate, and the spring is fixed inside the connecting plate.

[0012] Furthermore, it also includes a switch assembly, which includes a silicone block, a fixing plate, a support column, and a movable rod; the silicone block is snapped into the inside of the air inlet, the fixing plate is fixed to the outer surface of the silicone block, the support column is fixed to the upper surface of the air inlet, the movable rod is fixed to the upper surface of the fixing plate, and the movable rod passes through and is connected to the inside of the support column.

[0013] Furthermore, the movable rod has an internal mounting groove, and a connecting shaft is fixed inside the other side of the mounting groove.

[0014] Furthermore, a rotating column is rotatably connected to the outer surface of the connecting shaft, and a magnet block is fixed inside the rotating column.

[0015] Furthermore, the outer surface of the magnet block is magnetically connected to a magnet column, which is located inside the rotating column.

[0016] Furthermore, a connecting rod is fixed to the outer surface of the magnet column, and the connecting rod passes through and connects to the inside of the movable rod.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] I. This utility model, through its designed disassembly and assembly components, allows for quick and easy disassembly and assembly of the filter screen when replacement is required. A pulling force is applied to the guide plate, causing the limiting rod to disengage from the limiting post. A pulling force is then applied to the connecting frame to remove the filter screen from the air inlet. A rotating force is applied to the connecting frame to remove the threaded post from the filter screen, which is then rotated into the new filter screen. A pulling force is then applied to the guide plate, and the filter screen is placed back into the air inlet, allowing the limiting post to pass through the connecting plate. After the connecting frame and the connecting plate surface are in contact, the force applied to the guide plate is released, and the limiting rod springs back into the limiting post under the spring force. This solution provides a quick and simple way to disassemble and assemble the filter screen, improving the efficiency of filter screen replacement.

[0019] II. Based on the first beneficial effect, when used in conjunction with the switch assembly, to open the air inlet, a pulling force is applied to the fixed plate, causing the movable rod to move horizontally inside the support column until the surface of the rotating column is in contact with the surface of the support column. When the filter needs to be replaced, a pulling force is applied to the connecting rod, causing the magnet column to move into the movable rod. Under the action of the connecting shaft, a flipping force is applied to the rotating column, causing it to move into the mounting slot. A pulling force is then applied to the fixed plate, removing the movable rod from inside the support column, thus opening the air inlet. This solution effectively prevents new air from entering the disinfection box during operation, thus avoiding any impact on air quality. Attached Figure Description

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1 , Figure 2 and Figure 4 As shown, this embodiment is an auxiliary experimental tool for a solid-phase extraction apparatus, including:

[0033] The booster assembly includes a booster body 11, a disinfection box 12, and an air inlet 13; the disinfection box 12 is located on the top of the booster body 11, and the air inlet 13 is fixed inside one side of the disinfection box 12.

[0034] The booster body 11 is used to transport the liquid inside the solid phase extraction column to the required location, the disinfection box 12 is used to disinfect the air environment, and the air inlet 13 is used for air to flow into the booster body 11.

[0035] The assembly includes a filter screen 21, a threaded post 22, a connecting frame 23, a connecting plate 24, and a limiting post 25. The filter screen 21 is located inside the air inlet 13. The threaded post 22 is threadedly connected to the inside of the filter screen 21. The connecting frame 23 is fixed to the outer surface of the threaded post 22. The connecting plate 24 is fixed to the outer surfaces of both ends of the air inlet 13. The limiting post 25 is fixed to the outer surface of the connecting frame 23 and is connected through the inside of the connecting plate 24.

[0036] The filter screen 21 is used to filter the air entering the disinfection box 12 to prevent impurities from entering. The threaded post 22 is used to connect the filter screen 21 to the connecting frame 23. The connecting plate 24 can quickly install the connecting frame 23 in the required position. The limiting post 25 is used to fix the connecting frame 23 in the required position.

[0037] A limiting rod 26 is connected through the inside of the limiting post 25 and the connecting plate 24, and a guide plate 27 is fixed on the outer surface of the limiting rod 26.

[0038] The limiting rod 26 is used to confine the limiting post 25 inside the connecting plate 24, while the guide plate 27 facilitates changing the position of the limiting rod 26.

[0039] A spring 28 is fixed to the outer surface of the bottom end of the guide plate 27, and the spring 28 is fixed inside the connecting plate 24;

[0040] Spring 28 is used to provide elastic force so that the limit rod 26 can quickly spring back to its original position without being affected by external force.

[0041] Working principle: When the filter screen 21 needs to be replaced, a pulling force is applied to the guide plate 27, which drives the limiting rod 26 to disengage from the limiting post 25. Then, a pulling force is applied to the connecting frame 23 to remove the filter screen 21 from the air inlet 13. A rotating force is applied to the connecting frame 23 to remove the threaded post 22 from the filter screen 21. The threaded post 22 is then rotated into the new filter screen 21. A pulling force is applied to the guide plate 27, and the filter screen 21 is then placed into the air inlet 13, so that the limiting post 25 passes through the connecting plate 24. After the connecting frame 23 and the surface of the connecting plate 24 are in contact, the force applied to the guide plate 27 is released. Under the elastic force of the spring 28, the limiting rod 26 springs back into the limiting post 25.

[0042] This step allows for quick and easy disassembly and assembly of the filter screen 21, improving the efficiency of replacing the filter screen 21.

[0043] Please see Figures 1-3 As shown, this embodiment, based on the above embodiment, also includes a switch assembly. The switch assembly includes a silicone block 31, a fixing plate 32, a support column 33, and a movable rod 34. The silicone block 31 is snapped into the inside of the air inlet 13, the fixing plate 32 is fixed to the outer surface of the silicone block 31, the support column 33 is fixed to the upper surface of the air inlet 13, and the movable rod 34 is fixed to the upper surface of the fixing plate 32. The movable rod 34 passes through and is connected to the inside of the support column 33.

[0044] The silicone block 31 serves as a seal, thereby adjusting the opening and closing state of the air inlet 13. The fixing plate 32 is used to support and install the silicone block 31, and then to support and install the movable rod 34. The support column 33 is used for the movable rod 34 to move horizontally inside it.

[0045] The movable rod 34 has an internal mounting groove 35, and a connecting shaft 36 is fixed inside the other side of the mounting groove 35.

[0046] Mounting groove 35 is used to accommodate rotating column 37 and connecting shaft 36, with connecting shaft 36 used for rotating column 37 on its surface.

[0047] A rotating column 37 is rotatably connected to the outer surface of the connecting shaft 36, and a magnet block 38 is fixed inside the rotating column 37.

[0048] A magnetic column 39 is magnetically connected to the outer surface of the magnet block 38, and the magnet column 39 is located inside the rotating column 37.

[0049] A connecting rod 391 is fixed to the outer surface of the magnet post 39, and the connecting rod 391 passes through and connects to the inside of the movable rod 34.

[0050] The rotating column 37 is used to restrict the movable rod 34 to move inside the support column 33. The magnet block 38 is used to connect with the magnet column 39, thereby fixing the magnet column 39 inside the rotating column 37, thus restricting the rotating column 37 to the desired state. The connecting rod 391 facilitates changing the position of the magnet column 39.

[0051] Working principle: When it is necessary to open the air inlet 13, a pulling force is applied to the fixed plate 32, which drives the movable rod 34 to move horizontally inside the support column 33. The rotating column 37 is in contact with the surface of the support column 33. When it is necessary to replace the filter screen 21, a pulling force is applied to the connecting rod 391, which drives the magnet column 39 to move into the movable rod 34. Under the action of the connecting shaft 36, a flipping force is applied to the rotating column 37, which moves into the mounting groove 35. A pulling force is applied to the fixed plate 32 to remove the movable rod 34 from the support column 33, so that the air inlet 13 is in the open state.

[0052] This step effectively prevents fresh air from entering the disinfection box 12 during its operation, thus avoiding any impact on air quality.
