Description

Technical Field

[0001] The utility model relates to the technical field of biological detection, and more specifically to an automatic lifting reaction pool system. Background Art

[0002] Gene amplification technology, also known as the cell-free molecular cloning system or in vitro primer-directed enzymatic amplification of specific DNA (deoxyribonucleic acid) sequences, represents a major innovation in gene amplification technology. It can specifically amplify minute amounts of target DNA millions of times, significantly improving the analysis and detection capabilities of DNA molecules. It can even detect single molecules of DNA or samples containing as little as one target DNA molecule per 100,000 cells. Consequently, this method has rapidly gained widespread application and development in fields such as molecular biology, microbiology, medicine, and genetics. Due to its high sensitivity, strong specificity, rapidity, and simplicity, PCR (polymerase chain reaction) has demonstrated significant application value and promising prospects in the field of pathogenic microbiology.

[0003] During the PCR gene amplification process, the reaction tube needs to be placed in a reaction pool for heating. The temperature of the reaction pool will undergo repetitive rapid changes. An experiment usually requires multiple temperature cycles to complete. Therefore, when the reaction pool heats the liquid in the reaction tube, the liquid will evaporate to the top of the reaction tube due to the high temperature, forming condensation water, which affects the experimental results.

[0004] To prevent condensation, a heated lid assembly is typically used to press and heat the top of the reaction tube to prevent condensation. However, this requires manual flipping, pressing, and heating, which is time-consuming and labor-intensive, and has a low degree of automation.

[0005] Therefore, how to enable the hot cover assembly to automatically press the reaction tube to achieve the effect of saving time and labor and improving the degree of automation is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0063] The core of the utility model is to provide an automatic lifting reaction pool system, so that the hot cover assembly can automatically press the reaction tube, thereby saving time and labor and improving the degree of automation.

[0064] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0065] During PCR gene amplification, reaction tubes are heated in a reaction pool. This heat is transferred to the reaction tubes by a heating element (typically a semiconductor cooler). The lower half of the tubes is typically heated by the reaction pool. Because a single experiment typically requires multiple temperature cycles, when the reaction pool heats the liquid in the tubes, the high temperature can cause the liquid to evaporate and form condensation at the top of the tubes, affecting experimental results.

[0066] To prevent condensation on the top of the reaction tube, a heated cover assembly is typically added. This cover assembly is typically hinged, allowing it to swing between open and closed positions. Switching between these positions requires manual operation, which is time-consuming and labor-intensive.

[0067] Based on the above situation, an embodiment of the present invention discloses an automatic lifting reaction pool system, which can use a lifting drive system 300 to drive the reaction pool assembly 200 to perform a lifting action, so that the hot cover assembly can automatically press the reaction tube, thereby saving time and labor and improving the degree of automation.

[0068] like Figure 1-Figure 3 As shown, the automatic lifting reaction pool system disclosed in the embodiment of the present invention includes a support device 100, a reaction pool assembly 200, a thermal cover assembly 400, and a lifting drive system 300. Among them, the support device 100 provides a supporting foundation for the other components of the automatic lifting reaction pool system. Its structural form can be designed according to actual needs, as long as it can support and install other components.

[0069] The reaction pool assembly 200 is slidably arranged on the supporting device 100 along the lifting direction. Figure 8 As shown, the thermal cover assembly 400 is disposed on the support device 100 and is located above the reaction cell assembly 200. In this embodiment, the reaction cell assembly 200 is a movable component, while the thermal cover assembly 400 is a stationary component. The reaction cell assembly 200 is lifted and lowered to achieve movement toward and away from the thermal cover assembly 400.

[0070] When the reaction cell assembly 200 is moved toward the thermal cover assembly 400 to a corresponding position, the thermal cover assembly 400 can be fitted with the reaction cell assembly 200, and the thermal cover assembly 400 can heat the top of the reaction tube in the reaction cell assembly 200. When the reaction cell assembly 200 is moved away from the thermal cover assembly 400 to a corresponding position, the thermal cover assembly 400 can be separated from the reaction cell assembly 200, thereby facilitating the removal and installation of the reaction tube in the reaction cell assembly 200.

[0071] The lifting drive system 300 is arranged on the support device 100 and is used to provide driving force for the lifting movement of the reaction pool assembly 200, that is, to drive the reaction pool assembly 200 to perform lifting movement between the first position and the second position. When the reaction pool assembly 200 is in the first position, it is in contact with the thermal cover assembly 400. When the reaction pool assembly 200 is in the second position, it is separated from the thermal cover assembly 400.

[0072] like Figure 2 As shown, in a specific embodiment of the present invention, the lifting drive system 300 may include a drive motor system 310 and a connecting rod mechanism 320. The connecting rod mechanism 320 is used for converting the rotary motion of the drive motor system 310 into a lifting motion, so as to drive the reaction cell assembly 200 to do a lifting action between the first position and the second position. In the present embodiment, the rotary power output by the drive motor system 310 is converted into linear motion by the conversion mechanism of the motion trajectory through the connecting rod mechanism 320 to meet the demand of the motion trajectory of the reaction cell assembly 200. It should be noted that the lifting drive system 300 may also be realized by other mechanisms, such as by promoting the wedge block to do the linear motion in the horizontal direction through the cylinder, and the wedge block can output the motive force to the reaction cell assembly 200 along the height direction, and also can meet the motion demand of the reaction cell assembly 200.

[0073] like Figure 6 As shown, there are two linkage mechanisms 320, symmetrically arranged on the support device 100. The support device 100 may include two parallel support uprights 110, each of which is provided with a linkage mechanism 320. The two support uprights 110 may be connected and fixed by an intermediate connecting plate 120. The linkage mechanism 320 may be arranged on the outside of the support uprights 110, that is, on the side of the support uprights 110 away from the other support uprights 110.

[0074] The reaction pool assembly 200 has a certain weight, which is distributed on both sides of the reaction pool assembly 200 through two connecting rod mechanisms 320. By applying force on both sides of the reaction pool assembly 200, the reaction pool assembly 200 is driven to perform lifting movements, which can make the reaction pool assembly 200 more stable and reliable during movement.

[0075] The drive motor system 310 includes a drive motor 311 and a transmission shaft 312 that is transmission-connected to the drive motor 311. The two ends of the transmission shaft 312 are transmission-connected to two connecting rod mechanisms 320, respectively. That is, one drive motor 311 can simultaneously and synchronously drive the two connecting rod mechanisms 320 to perform the same action under the action of the transmission shaft 312. A driving gear 315 can be provided on the output shaft of the drive motor 311, and a driven gear 316 can be provided on the transmission shaft 312. The driving gear 315 and the driven gear 316 are engaged to achieve a transmission connection between the drive motor 311 and the transmission shaft 312. It should be noted that the drive motor 311 and the transmission shaft 312 can also be transmission-connected by other means, such as chain drive, synchronous belt drive, etc., and are not limited to gear drive.

[0076] The drive motor 311 can be fixed to one of the support vertical plates 110 via a motor connecting plate 313, and the motor connecting plate 313 can be fastened to one of the support vertical plates 110 via a screw 314. The transmission shaft 312 can be supported between the two support vertical plates 110. The support vertical plates 110 are provided with a support hole for supporting the transmission shaft 312. In order to reduce the friction when the transmission shaft 312 rotates, a shaft bushing 317 can be provided in the support hole.

[0077] In this embodiment, the linkage mechanism 320 may include a rotating disk 321, a transmission link 322, a first rocker arm 323, and a second rocker arm 324. The rotating disk 321 is in transmission connection with the transmission shaft 312. Specifically, the two ends of the transmission shaft 312 penetrate the support uprights 110 on both sides, and the rotating disk 321 is mounted on the outer sides of the support uprights 110, so that the transmission shaft 312 can drive the rotating disk 321 to rotate.

[0078] The first end of the first rocker arm 323 and the first end of the second rocker arm 324 are hinged through the first rocker arm shaft 325, the second end of the second rocker arm 324 is hinged to the support device 100, and the second end of the second rocker arm 324 can be hinged to the support device 100 through the second rocker arm shaft 326.

[0079] The second end of the first rocker arm 323 is provided with a sliding shaft 327. The rotating disk 321 serves as the input end of the connecting rod mechanism 320 for receiving power from the transmission shaft 312. The sliding shaft 327 serves as the output end of the connecting rod mechanism 320 for driving the reaction pool assembly 200 to perform lifting movements.

[0080] In order to ensure that the sliding dial shaft 327 can move up and down according to the predetermined route, the support device 100 is provided with a lifting slot 112 (such as Figure 7 As shown in FIG, the sliding dial shaft 327 is directly or indirectly connected to the reaction pool assembly 200. Those skilled in the art can design the trajectory of the lifting chute 112 according to the required movement path of the reaction pool assembly 200.

[0081] One end of the transmission link 322 is hinged to the rotating disk 321, and the hinge point between the transmission link 322 and the rotating disk 321 is offset from the rotation center of the rotating disk 321, so that when the rotating disk 321 rotates, the transmission link 322 can be driven to swing. The other end of the transmission link 322 is hinged to the first rocker shaft 325. When the transmission link 322 is driven by the rotating disk 321, it can generate a pulling force on the first rocker shaft 325. Because the second end of the second rocker arm 324 is hinged to the support device 100 via the second rocker shaft 326, when the first rocker shaft 325 is pulled, the first rocker shaft 325 rotates around the second rocker shaft 326. The sliding shaft 327 slides in cooperation with the lifting slot 112. When the first rocker shaft 325 rotates around the second rocker shaft 326, the sliding shaft 327 can slide up and down along the lifting slot 112, thereby driving the reaction pool assembly 200 to move up and down.

[0082] In order to enable the reaction pool assembly 200 to accurately move to the first position and the second position, in this embodiment, the lifting drive system 300 may further include a positioning assembly 340 for positioning the first position and the second position of the reaction pool assembly 200. The positioning assembly 340 may include a first position sensor 331, a second position sensor 342, and a trigger.

[0083] The trigger is fixed to the rotating disk 321 so that it can rotate with the rotating disk 321. When the trigger rotates with the rotating disk 321 to sense the first position sensor 331, the reaction pool assembly 200 is in the first position. When the trigger senses the second position sensor 342, the reaction pool assembly 200 is in the second position.

[0084] When the trigger member senses the first position sensor 331, the drive motor 311 can be controlled to stop rotating so that the reaction pool assembly 200 remains in the first position; when the trigger member senses the second position sensor 342, the drive motor 311 can be controlled to stop rotating so that the reaction pool assembly 200 remains in the second position.

[0085] It should be noted that in order to utilize the dead point position of the connecting rod mechanism, when the reaction pool assembly 200 is in the first position, the first rocker arm 323 and the second rocker arm 324 are located on the same straight line and are arranged vertically, that is, the gravity of the reaction pool assembly 200 passes through, and the first rocker arm 323 and the second rocker arm 324 act on the first rocker arm shaft 325, and no torque can be formed, that is, the first rocker arm shaft 325 cannot be driven to rotate around the second rocker arm shaft 326 by the gravity of the reaction pool assembly 200, thereby improving the stability of the reaction pool assembly 200 and eliminating the worry that the reaction pool assembly 200 will fall.

[0086] Since the reaction pool assembly 200 has a certain weight, the reaction pool assembly 200 is connected only by the sliding dial shaft 327. Since the connection point between the sliding dial shaft 327 and the reaction pool assembly 200 is small, the connection is unreliable, and the reaction pool assembly 200 and the sliding dial shaft 327 are easily disconnected, affecting the reliability of the product.

[0087] Based on this, in a specific embodiment of the present invention, Figure 6 As shown, the support device 100 may further include a guide slot 130 disposed on the inner side of the support upright plate 110 . The guide slot 130 may be fixed to the inner side of the support upright plate 110 by fasteners.

[0088] The guide groove body 130 is provided with a shaft guide groove 132 that is connected to the lifting chute 112 and slides with the sliding shaft 327, so that the sliding shaft 327 can simultaneously penetrate the lifting chute 112 and the shaft guide groove 132. The guide groove body 130 is also provided with a slider guide groove 131. The reaction pool assembly 200 is connected to the guide block assembly 330. Figure 4 As shown in the figure). Figure 5 As shown, the guide block assembly 330 includes a guide block 331 that is slidably engaged with the slider guide groove 131 , and the sliding dial shaft 327 is connected to the guide block assembly 330 .

[0089] To prevent the guide block 331 from disengaging from the slider guide slot 131, the slider guide slot 131 is a sliding slot having a limiting wall. The guide block 331 is inserted into the slider guide slot 131 from one end of the slider guide slot 131. The limiting wall prevents the guide block 331 from disengaging from the slider guide slot 131 in a direction parallel to the slide shaft 327. In this embodiment, by connecting the guide block assembly 330 to the reaction cell assembly 200 and disposing the guide slot body 130 on the inner side of the support plate 110, the guide block 331 of the guide block assembly 330 slidably engages with the slider guide slot 131 of the guide slot body 130, making the reaction cell assembly 200 more stable, reliable, and smooth during lifting and lowering.

[0090] Since the reaction pool assembly 200 contacts the hot cover assembly 400 during the rising process, the contact force needs to be strictly controlled, otherwise it is easy to damage the reaction tube, resulting in damage to the reaction tube. In order to overcome this problem, in this embodiment, the guide block assembly 330 is improved. Figure 5 As shown, in this embodiment, the guide block assembly 330 may include a lifting plate 332 , a guide block 331 , a guide shaft 333 and an elastic pressing member 334 .

[0091] Among them, the guide block 331 is fixed on the lifting plate 332, and the guide shaft 333 is fixed on the reaction tank assembly 200 and slides with the lifting plate 332. In order to facilitate the installation of the guide block 331 and the guide shaft 333, the lifting plate 332 can be designed as an L-shaped plate, the guide block 331 is fixed on a vertical plate of the lifting plate 332, and the guide shaft 333 is slidably matched on the other vertical plate of the lifting plate 332. The lifting plate 332 can have a certain length so that multiple guide shafts 333 can be installed on the lifting plate 332 at the same time to improve the stability of the lifting plate 332 sliding along the guide shaft 333. At the same time, in order to further ensure that the lifting plate 332 slides smoothly along the guide shaft 333, a bushing 335 is embedded in the guide hole where the lifting plate 332 and the guide shaft 333 cooperate to reduce friction.

[0092] The elastic pressing member 334 is sleeved on the guide shaft 333 , and one end of the elastic pressing member 334 abuts against the lifting plate 332 , and the other end abuts against the reaction pool assembly 200 .

[0093] When the drive motor 311 drives the transmission shaft 312 to rotate, the rotating disk 321 follows the synchronous rotation, and the rotating disk 321 can drive the transmission connecting rod 322 to swing. The transmission connecting rod 322 then drives the first rocker arm shaft 325 to rotate around the second rocker arm 324, and the sliding dial shaft 327 drives the guide block 331 to slide up and down along the slider guide groove 131. Because the guide shaft 333 is fixed to the reaction cell assembly 200, when the guide block 331 rises, the lifting plate 332 acts on the reaction cell assembly 200 with the elastic pressing member 334, so that the reaction tube in the reaction cell assembly 200 can be buffered by the elastic pressing member 334 when contacting with the hot cover assembly 400, avoiding crushing the reaction tube. When the reaction cell assembly 200 rises into place, the spring force of the elastic pressing member 334 can ensure the compression of the reaction cell assembly 200 and the hot cover assembly 400.

[0094] A limit stop is provided at the lower end of the guide shaft 333 to prevent the lifting plate 332 from detaching from the guide shaft 333 due to gravity. When the guide block 331 descends, the lifting plate 332 exerts force on the reaction cell assembly 200 through the guide shaft 333, causing the reaction cell assembly 200 to descend with it and detach from the thermal cover assembly 400.

[0095] In this embodiment, the guide groove body 130 further includes a guide groove stopper 133 located at the bottom of the slider guide groove 131. When the reaction cell assembly 200 is in the second position, the guide block 331 abuts against the guide groove stopper 133. The guide groove stopper 133 limits the guide block 331, thereby preventing the reaction cell assembly 200 from continuing to descend and separating from the support device 100.

[0096] like Figure 3As shown, in this embodiment, the heat cover assembly 400 may include a heat cover fixing plate 410, a heat cover 450 and a heat cover heating film 430. The support device 100 is provided with a positioning slot 111 (such as Figure 2 As shown in FIG. 1 , the inner tops of the two support plates 110 are provided with positioning slots 111. The positioning slots 111 should extend to at least one end of the support plates 110, allowing the heat cover fixing plate 410 to slide into the positioning slots 111 from this end. Accordingly, the heat cover fixing plate 410 is provided with positioning slides 412 that slidably engage with the positioning slots 111. After the heat cover fixing plate 410 engages with the positioning slots 111 and slides into place, it can be locked with a jackscrew to prevent it from sliding further.

[0097] The thermal cover heating film 430 is mounted on the thermal cover 450 to heat the thermal cover 450, which is fixed to the thermal cover fixing plate 410. One side of the thermal cover heating film 430 may be provided with an adhesive backing, which allows it to be attached to the thermal cover 450 to heat the thermal cover 450. The heated thermal cover 450 further increases the temperature at the top of the reaction tube.

[0098] To facilitate observation of the reaction tube, in this embodiment, the thermal cover assembly 400 may further include a thermal cover plate 420 and an optical glass 440. The thermal cover 450 has a mounting groove recessed toward a side away from the thermal cover fixing plate 410. The optical glass 440 is embedded in the mounting groove and disposed between the thermal cover 450 and the thermal cover heating film 430.

[0099] The thermal cover 450, the thermal cover plate 420 and the thermal cover heating film 430 are all provided with observation holes at the positions corresponding to the reaction tube installation positions of the reaction cell assembly 200. The thermal cover 450 is fixed on the thermal cover plate 420, and the thermal cover plate 420 is fixed on the thermal cover fixing plate 410, and the area corresponding to the optical glass 440 on the thermal cover fixing plate 410 is provided with a hollow groove 411. The situation of the reaction tube can be observed through the hollow groove 411, the optical glass 440 and the observation hole. The position of the hollow groove 411 can also be provided with an embedded groove, and the assembled components of the thermal cover 450, the thermal cover plate 420 and the thermal cover heating film 430 are embedded in the embedded groove, so that the side of the thermal cover assembly 400 facing the reaction cell assembly 200 is in a flat state.

[0100] like Figure 4 As shown, in a specific embodiment of the present invention, the reaction cell assembly 200 includes a reaction cell 210, a reaction cell cover 220, a semiconductor cooling plate 240, and a heat sink 230. The reaction cell 210 has a reaction tube mounting position for positioning a reaction tube, so that the reaction tube can be positioned in the reaction tube mounting position and controlled in temperature by the reaction cell 210.

[0101] The semiconductor cooling chip 240 is arranged between the reaction pool 210 and the heat sink 230 to adjust the temperature of the reaction pool 210. The reaction pool 210 is pressed against the semiconductor cooling chip 240 by the reaction pool cover 220, and the reaction pool cover 220 can be locked to the heat sink 230 by fasteners.

[0102] The semiconductor refrigeration sheet 240 is used to heat and cool the reaction pool 210, thereby performing a temperature cycle on the reagents in the reaction tube. When placing the reaction pool 210, a heat-conducting medium should be applied to the lower surface of the reaction pool 210 to increase the heat conduction efficiency. A reaction pool cover 220 is also installed above the reaction pool 210. The reaction pool cover 220 and the radiator 230 are locked with screws to press the reaction pool 210 onto the upper surface of the semiconductor refrigeration sheet 240.

[0103] To accelerate the heat dissipation of the radiator 230, the reaction pool assembly 200 may further include a fan assembly 250, which includes a fan cover 251 and a heat dissipation fan 252. The fan cover 251 covers the heat dissipation teeth of the radiator 230, and the heat dissipation fan 252 is used to blow air into the fan cover 251 to dissipate heat for the radiator 230.
