Description

Technical Field

[0001] This utility model relates to the field of adhesive circuit connection technology, and in particular to an adhesive circuit connection device for a capillary electrophoresis apparatus. Background Technology

[0002] The gel circuit connection device of the capillary electrophoresis apparatus is a key component used to realize gel delivery, filling and tubing connection. Its design and function directly affect the electrophoretic separation effect and the stability of the instrument. The gel is uniformly filled into the capillary by pressure drive to form the separation medium, which is the basis of electrophoretic separation. The main structure includes a gel storage container, tubing system and drive components.

[0003] Existing technologies often result in gel residues remaining in pipe corners or valve gaps during the filling process, leading to sedimentation over time. Furthermore, seals are prone to aging due to pressure or chemical corrosion, causing liquid leakage. Current technologies use a double-layer conical filter array at the outlet of the gel storage container to intercept particulate impurities in the gel. However, this design makes it inconvenient to disassemble, replace, and clean the filter afterward, and the accuracy of test results will be significantly reduced over long-term use. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 3 and Figure 4An embodiment of this utility model provides a capillary electrophoresis apparatus gel circuit connection device, including a gel storage tank 1. A filter mechanism 2 is installed on the upper inner side of the gel storage tank 1. The filter mechanism 2 is used to filter the gel. A sealing mechanism 3 is installed on the lower right side of the gel storage tank 1. The sealing mechanism 3 is used to seal. The filter mechanism 2 includes a secondary filter cylinder 201. The secondary filter cylinder 201 is installed on the upper inner side of the gel storage tank 1. A fixing plate 204 is fixedly connected to the top of the secondary filter cylinder 201. A primary filter cylinder 202 is fixedly connected to the middle bottom of the fixing plate 204. Slider blocks 203 are fixedly connected to the lower outer side of the fixing plate 204. Multiple fixing posts 205 are fixedly connected at equal intervals to the top of the fixing plate 204. Multiple sliding grooves 206 are equidistantly opened in the middle top of the gel storage tank 1. The sliding grooves 206 are slidably connected to the sliders 203. Specifically, during the installation of the filter mechanism 2, the operator needs to hold the fixing column 205 and precisely align the slider 203 with the groove 206 on the glue storage tank 1. By applying a downward pushing force along the groove 206, the slider 203 slides smoothly within the groove 206, thereby securely installing the filter mechanism 2 inside the glue storage tank 1. The fixing column 205 provides a gripping point for the installation and disassembly of the filter mechanism 2, improving operational convenience and installation efficiency. After installation, during the conveying process, the colloid passes through the dual filtration structure of the secondary filter cartridge 201 and the primary filter cartridge 202 in sequence. The secondary filter cartridge 201 and the primary filter cartridge 202 adopt a graded filtration design to achieve deep filtration of impurities in the colloid. This dual filtration mechanism can effectively intercept various impurity particles in the colloid, preventing impurities from accumulating in the pipeline and forming blockages, thus ensuring the accuracy and reliability of the test data.

[0019] Reference Figure 1 , Figure 5 and Figure 6 The sealing mechanism 3 includes a bolt 301, which is installed at the right end of the glue storage tank 1. A fixing ring 302 is installed at the left end of the bolt 301. A rubber ring 303 is installed on the left side of the fixing ring 302. A rubber tube 308 is installed at the inner left end of the rubber ring 303. A glue outlet tube 304 is slidably connected to the outer left end of the rubber tube 308. An annular groove 306 is opened in the middle of the top of the glue storage tank 1. A threaded cap 305 is threadedly connected to the middle of the top of the glue storage tank 1. A conical filter 307 is installed on the inner left end of the glue outlet tube 304. The glue storage tank 1 and the glue outlet tube 304 pass through each other. The glue outlet tube 304 is connected to the air pump 9. The glue outlet tube 304 is threadedly connected to the bolt 301. The bolt 301 is rotatably connected to the fixing ring 302. Specifically, during the connection operation of the dispensing hose, the bolt 301 is rotated to connect it to the first dispensing hose 304. This connection method enhances the sealing performance of the pipeline system and facilitates subsequent disassembly and maintenance. The bolt 301 has a retaining ring 302 inside, which is connected to the second dispensing hose 6. During the pipeline connection process, the retaining ring 302 ensures precise alignment of the openings of the second dispensing hose 6 and the first dispensing hose 304. A rubber ring 303 is installed at the connection point of the two dispensing hoses, forming a sealing barrier. The rubber tube 308 inside the second dispensing hose 6 connects the second dispensing hose 6 and the first dispensing hose 304 via the bolt 301. After the connection is tightened, the rubber tube 308 is embedded inside the connection, further eliminating tiny gaps and effectively preventing colloid leakage. This ensures the airtightness of the entire colloid outlet pipeline system, thereby guaranteeing the authenticity and reliability of the data during the testing process. The conical filter 307 installed inside the colloid inlet tube 8 performs secondary filtration on the colloid entering the system. This filter intercepts and separates impurities in the colloid, further improving the purity of the colloid and preventing impurities from interfering with the test results. At the same time, the threaded cap 305 of the colloid storage tank 1 is tightly connected to the tank body using a threaded connection, achieving a reliable seal between the tank body and the threaded cap 305. This effectively prevents colloid evaporation or the entry of external impurities, providing multiple guarantees for the airtightness of the entire colloid delivery and testing system.

[0020] Reference Figure 2 and Figure 5 A handle 4 is fixedly connected to the upper middle part of the outer side of the glue storage tank 1 at both the front and rear ends. An anti-slip pad 5 is installed at the middle of the top of the glue storage tank 1. A waste liquid tank 7 is installed on the right side of the glue storage tank 1. A glue outlet pipe 6 is connected to the left end of the waste liquid tank 7. An air pump 9 is installed on the right side of the inner bottom wall of the glue storage tank 1. A glue inlet pipe 8 is connected to the lower middle left side of the air pump 9. A cover 11 is threadedly connected to the middle of the top of the waste liquid tank 7. An anti-slip pad 10 is fixedly connected to the outer wall of the cover 11. Specifically, a handle 4 is connected to the outside of the glue storage tank 1, providing a reliable gripping point for operators to carry and move the glue storage tank 1. The glue storage tank 1 is equipped with an anti-slip pad 5, which can effectively increase the friction of the contact surface, prevent objects placed on it from sliding, and increase operational stability. A waste liquid tank 7 is installed on the right side of the glue storage tank 1 for collecting the used glue waste liquid. An air pump 9 is installed on the inner bottom wall of the glue storage tank 1. The air pump 9 is connected to a glue inlet pipe 8. The operation of the air pump 9 can deliver the glue from the glue inlet pipe 8 to the required location. The top of the waste liquid tank 7 is equipped with a cap 11 by a threaded connection, which is convenient for opening and closing. An anti-slip pad 10 is connected to the outer wall of the cap 11, making it easier and more stable for operators to unscrew or tighten the cap 11, and preventing slippage.

[0021] Working principle: The operator holds the fixed column 205, aligns the slider 203 with the slide groove 206, and moves it downward along the slide groove 206, so that the filter mechanism 2 is installed inside the glue storage tank 1 through the slider 203 and the slide groove 206. The fixed column 205 facilitates the installation and disassembly of the filter equipment. The glue will enter the tank through the secondary filter cartridge 201 and the primary filter cartridge 202. The two filtrations can filter out the impurities in the glue more deeply and prevent the glue from clogging the pipes and affecting the instrument's detection results. Rotate bolt 301 to connect it to dispensing tube 1 304, enhancing sealing and ease of disassembly. Bolt 301 contains a retaining ring 302, which is fixed to dispensing tube 2 6. During connection, dispensing tube 2 6 and dispensing tube 1 304 are effectively aligned. Rubber ring 303 provides a seal. Dispensing tube 2 6 contains a rubber tube 308. When dispensing tube 2 6 and dispensing tube 1 304 are connected by bolt 301, the rubber tube 308 is installed inside the connection, effectively preventing gaps and enhancing the accuracy of test results. Inside dispensing tube 8, there is a conical filter 307 for further filtration of the colloid. The threaded cap 305 of the storage tank 1 is connected to the tank body via threads, which also improves the sealing effect.
