Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory technology; more specifically, it relates to a nucleic acid extractor. Background Technology
[0002] Nucleic acid extractors are key equipment in molecular diagnostics for clinical laboratories, primarily used for automated, high-throughput extraction of DNA / RNA from samples. Their core principle is based on magnetic bead or silica membrane adsorption, rapidly separating and purifying nucleic acids through steps such as lysis, binding, washing, and elution. They are widely used in infectious disease detection, tumor gene detection, and genetic disease diagnosis, ensuring the accuracy and reproducibility of subsequent PCR and sequencing experiments.
[0003] Currently, existing nucleic acid extractors generate significant heat during prolonged operation, and most rely on fans for cooling. The noise from these fans can be quite loud and disruptive to operators, potentially affecting the extraction process. Furthermore, the vibrations from the fans can interfere with the extraction process, reducing the instrument's practicality. Additionally, the fixed control panels of most existing instruments require operators to move to the front of the panel when needed, hindering timely operation and further compromising usability. Therefore, a novel nucleic acid extractor is urgently needed to address these issues. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nucleic acid extractor to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a nucleic acid extractor, comprising:
[0006] The extraction chamber has a heat dissipation structure on one side of its outer surface and an adjustment structure on the outer surface at the middle position of the upper end of the extraction chamber, with an operation panel at the upper end of the adjustment structure.
[0007] The heat dissipation structure includes a heat dissipation plate, and the outer surface of one side of the heat dissipation plate is engaged with the outer surface of one side of the extraction chamber.
[0008] The adjustment structure includes a mounting box, which is fixedly connected to the outer surface of the upper middle position of the extraction chamber.
[0009] Preferably, the heat dissipation structure further includes heat dissipation fins, and multiple sets of heat dissipation fins are provided. All sets of heat dissipation fins are fixedly connected to the outer surface of the other side of the heat dissipation plate. A dust cover is fitted onto the outer surface of the heat dissipation plate and the heat dissipation fins. A connecting hole is opened inside the four corners of the outer surface of the dust cover. A mounting bolt is inserted into the four sets of connecting holes. The four sets of mounting bolts are threaded into the inner surface of the four corners of the extraction chamber. A heat dissipation hole is opened inside the outer surface of the outer side of the dust cover. This design allows the dust cover to be positioned relative to the extraction chamber by threading the mounting bolts inserted into the connecting holes into the interior of the extraction chamber.
[0010] Preferably, a trapezoidal groove is formed inside the outer surface of one side of the heat sink, and a trapezoidal block is formed on the outer surface of one side of the extraction chamber. The inner dimensions of the trapezoidal groove are adapted to the outer dimensions of the trapezoidal block. The heat dissipation fins are evenly arranged on the outer surface of the other side of the heat sink, and the heat dissipation fins are made of copper alloy. The heat dissipation holes are coaxially and evenly arranged inside the outer surface of the dust cover on the outer side. This design, by engaging the trapezoidal groove with the outer surface of the trapezoidal block, can position the heat dissipation fins relative to the extraction chamber.
[0011] Preferably, the adjustment structure further includes a rotating groove, which is located inside the mounting box. A support rod is inserted inside the rotating groove. A connecting rod is hinged to the outer surface of the upper end of the support rod, and a tightening bolt is threaded into the inner surface of the outer surface of one end of the connecting rod. An operating plate is mounted on the outer surface of one side of the connecting rod. This design allows the support rod to move up and down inside the rotating groove.
[0012] Preferably, the bottom wall surface of the rotating groove is provided with a toothed groove, the lower end of the support rod is provided with a toothed disc, and the internal dimensions of the toothed groove are adapted to the external dimensions of the toothed disc, and the internal height dimension of the rotating groove is adapted to the external height dimension of the toothed disc. This design allows the position of the support rod to be positioned by the toothed disc engaging with the inside of the toothed groove.
[0013] Preferably, the outer surface of the clamping bolt is in contact with the outer surface of the support rod. This design allows the clamping bolt to move inward by rotating, and to clamp the outer surface of the support rod, thereby positioning the connecting rod.
[0014] The technical effects and advantages of this utility model are as follows: By fitting the trapezoidal groove onto the outer surface of the trapezoidal block, the heat dissipation plate can be installed on the outer surface of one side of the extraction chamber. The extraction chamber can then be cooled by multiple sets of heat dissipation fins. Furthermore, the high thermal conductivity of the copper alloy material of the heat dissipation fins can significantly improve the heat dissipation capacity of the equipment. Thus, while cooling the equipment, noise and vibration can be reduced, thereby improving the practicality of the equipment to a certain extent.
[0015] By moving the support rod upwards, the gear disc disengages from the tooth groove, allowing the support rod to be rotated to adjust the horizontal direction of the control panel. Loosening the support rod allows the gear disc to re-engage into the tooth groove, thus positioning the control panel horizontally. Hinging the rotating connecting rod to the appropriate position and rotating the clamping bolt to press it against the outer surface of the support rod allows for adjustment and positioning of the control panel longitudinally. This allows operators to easily operate the control panel from different positions without having to move to the front of the control panel, improving the equipment's practicality. Furthermore, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the morphology of each structure described in the following embodiments is merely illustrative. The nucleic acid extractor involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Example 1
[0023] like Figure 1 and Figure 2 As shown, this embodiment proposes a nucleic acid extractor, including:
[0024] Extraction chamber 1, with a heat dissipation structure 2 on one side of the outer surface of extraction chamber 1, and an adjustment structure 3 on the outer surface at the middle position of the upper end of extraction chamber 1, with an operation panel 4 on the upper end of the adjustment structure 3;
[0025] The heat dissipation structure 2 includes a heat dissipation plate 21, with one outer surface of the heat dissipation plate 21 engaging with the outer surface of one side of the extraction chamber 1. The heat dissipation structure 2 also includes heat dissipation fins 22, with multiple sets of fins 22, all fixedly connected to the outer surface of the other side of the heat dissipation plate 21. A dust cover 23 is fitted over the outer surfaces of the heat dissipation plate 21 and the heat dissipation fins 22. The dust cover 23 has connecting holes 24 at the four corners of its outer surface, and mounting bolts 25 are inserted into each of the four connecting holes 24. 5 are threaded to the inside of the four corners of the outer surface of the extraction chamber 1. The dust cover 23 has heat dissipation holes 26 inside the outer surface of the outer side. The heat dissipation plate 21 has a trapezoidal groove inside the outer surface of the outer side. The outer surface of the extraction chamber 1 has a trapezoidal block, and the inner size of the trapezoidal groove matches the outer size of the trapezoidal block. The heat dissipation fins 22 are evenly arranged on the outer surface of the other side of the heat dissipation plate 21, and the heat dissipation fins 22 are made of copper alloy. The heat dissipation holes 26 are coaxially and evenly arranged inside the outer surface of the outer side of the dust cover 23.
[0026] In this embodiment, the trapezoidal groove engages with the outer surface of the engaging block, providing greater stability during engagement. This allows the heat sink 21 to be positioned relative to the extraction chamber 1, enabling the heat sink 22 to dissipate heat from the extraction chamber 1. Furthermore, the high thermal conductivity of the copper alloy material of the heat sink 22 ensures more efficient heat dissipation. The dust cover 23 is installed on the outer surface of the extraction chamber 1 via the threaded connection of the mounting bolt 25, preventing external dust from adhering to the outer surface of the heat sink 22 and affecting its heat dissipation. The heat dissipation holes 26 facilitate the expulsion of heat from the heat sink 22.
[0027] Example 2
[0028] like Figure 3 and Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:
[0029] The adjustment structure 3 includes a mounting box 31, which is fixedly connected to the outer surface of the upper middle position of the extraction chamber 1. The adjustment structure 3 also includes a rotating groove 32, which is opened inside the mounting box 31. A support rod 33 is inserted inside the rotating groove 32. A toothed groove is opened inside the bottom wall surface of the rotating groove 32. A toothed disc is provided at the lower end of the support rod 33. The internal dimensions of the toothed groove are adapted to the external dimensions of the toothed disc. The internal height dimension of the rotating groove 32 is adapted to the external height dimension of the toothed disc. This design allows the support rod 33 to be rotated by moving the support rod 33 upward, causing the toothed disc to disengage from the toothed groove and enter the rotating groove 32. This allows the support rod 33 to rotate, causing the toothed disc to rotate inside the rotating groove 32. This allows the direction of the support rod 33 to be adjusted. Releasing the support rod 33 allows the toothed disc to re-engage into the toothed groove. The toothed disc engages into the toothed groove more stably, allowing the position of the support rod 33 to be positioned. This allows the horizontal direction of the operation plate 4 to be adjusted.
[0030] A connecting rod 34 is hinged to the outer surface of the upper end of the support rod 33, and a clamping bolt 35 is threaded onto the inner surface of the outer surface of one end of the connecting rod 34. The operating plate 4 is installed on the outer surface of one side of the connecting rod 34. The outer surface of the clamping bolt 35 is in contact with the outer surface of the support rod 33. By rotating the clamping bolt 35 counterclockwise, the clamping bolt 35 is disengaged from the outer surface of the support rod 33, allowing the connecting rod 34 to be hinged and rotated to a suitable position. By rotating the clamping bolt 35 clockwise, the clamping bolt 35 is pressed against the outer surface of the support rod 33, thereby positioning the angle of the connecting rod 34. This allows the longitudinal angle of the operating plate 4 to be adjusted.
[0031] Working Principle: When using the equipment, firstly, the heat dissipation plate 21 is installed by engaging the trapezoidal slot with the outer surface of the trapezoidal block. Then, the four sets of mounting bolts 25 are rotated into the interior of the four corners on one side of the extraction chamber 1 to install the dust cover 23. The heat dissipation fins 22 can then dissipate heat from the equipment. Next, when the operation panel 4 needs to be operated and the operator is not directly in front of the equipment, the support rod 33 can be pulled upwards and rotated. After rotating the support rod 33 to the appropriate position, the support rod 33 is released, and the gear plate engages with the interior of the gear groove. This adjusts the horizontal direction of the operation panel 4 and positions the support rod 33. Then, the rotating connecting rod 34 is hinged according to actual needs, thereby adjusting the longitudinal angle of the operation panel 4. The position of the connecting rod 34 is then positioned by rotating the tightening bolt 35 clockwise. This allows for relatively quick and convenient operation of the operation panel 4. The above is the complete working principle of this utility model.
[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
