Description

Technical Field

[0001] The invention relates to the technical field of molecular identification of traditional Chinese medicines, and in particular to a water bath device for molecular identification of traditional Chinese medicines. Background Art

[0002] The core function of water bath operation in molecular identification of Chinese herbal medicines is to achieve precise temperature control, providing a constant temperature environment guarantee for key molecular biology experimental links such as DNA extraction, PCR amplification and enzyme digestion. Its core functions include: DNA denaturation / renaturation, such as thermal denaturation of template DNA before PCR (95°C) or temperature maintenance of nucleic acid hybridization experiments; enzymatic reactions, restriction endonuclease digestion (37°C) or reverse transcription reactions (42-50°C) and other reactions that rely on a constant temperature environment; sample processing temperature maintenance, such as cell lysis during DNA extraction by CTAB method (65°C) or the sol process of agarose gel recovery (45-55°C), etc.; as a low-cost constant temperature device, it provides basic temperature control support when there is a lack of professional instruments. For example, when there is no PCR instrument, the water bath can achieve simple temperature control.

[0003] Since in some reaction systems (such as CTAB method for DNA extraction), long-term standing may cause the sample and the lysate to separate, shaking can be used to fully mix the two, thereby improving the efficiency of cell lysis and DNA extraction. Therefore, in the actual operation process, in order to promote the full mixing of the reactants and accelerate the reaction process, it is necessary to take out the EP tube containing the sample from the water bath and shake it at intervals. It is worth noting that during the period of non-shaking standing of the sample, the solid components in the sample will still gradually settle to the bottom of the tube due to gravity. This dynamic process of repeated precipitation and resuspension will cause fluctuations in the contact area between the cell wall / membrane and the lysate, which not only affects the stability of the cell lysis efficiency, but also causes part of the DNA to be entrained in the precipitate, making it difficult to completely free to the supernatant. In addition, manual shaking cannot fully mix the reactants, and there is a risk of scalding caused by steam or hot water splashing when operating in a high-temperature water bath. Summary of the invention

[0004] One of the purposes of the present invention is to provide a water bath device for molecular identification of traditional Chinese medicine, which uses the screw connection between the water bath and the main shell assembly as the installation basis, cooperates with the sliding connection formed by the cylindrical seat fixedly connected to the outer side of the main shell assembly and the ball head seat elastically slidingly connected to the outer bottom end of the fixed rod and the outer top surface of the cylindrical seat and the guide slide groove, so as to form multiple mixing and swinging actions for the EP tube loaded on the placement rack, thereby ensuring that the reactants are fully mixed.

[0005] The object of the present invention is achieved through such a technical solution, a water bath device for molecular identification of Chinese medicinal materials, comprising a main shell component, a water bath component, a joint swing frame component and a placement frame component, the water bath component comprises a water bath tank, the joint swing frame component comprises a connecting rod, a fixing rod and a columnar seat, and the placement frame component comprises a placement frame, a pipe sleeve, an EP pipe and a pushing hole; The water bath is screwed to the inner top of the main shell assembly, a main connecting rod is symmetrically screwed to one side of the inner part of the water bath, and the connecting rod is screwed between the other ends of the main connecting rods. The main connecting rods and the connecting rods form a parallelogram structure, and a fixed rod is fixed to the top of the rotating shaft at one end of one group of main connecting rods, and a cylindrical seat is fixed to the outer side of the main shell assembly. The other end of the fixed rod is slidably connected to a ball head seat elastically downward, and a guide groove is fixed to the outer top surface of the cylindrical seat. The ball head seat is slidably connected to both the outer top surface of the cylindrical seat and the guide groove; A conical plug column is fixed on one side of the top of each set of main connecting rods, a conical plug sleeve is fixed on one side of the placement rack, and after the other side of the placement rack is slidably inserted with the other side of the main connecting rod, the conical plug sleeve can be snap-fitted with the conical plug column; The pipe sleeves are arranged and fixedly connected to the placement rack, and EP pipes can be inserted and installed in each set of pipe sleeves. Push holes are opened in the main body of the placement rack at a position directly opposite to the conical sockets, and an outward-moving socket is fixed in the middle of the top of the placement rack.

[0006] The use process of the technical solution of the present invention is as follows: The water bath is used to hold distilled water, which is heated to a set temperature by a heating mechanism. The EP tube is used to hold the DNA sample of Chinese medicinal materials and is tightly sealed. After the set water temperature of the distilled water in the water bath is stabilized, the EP tube containing the DNA sample of the Chinese medicinal materials is inserted and installed into the tube sleeve in place while the placement rack is connected to the main connecting rod, and the EP tube is immersed in the distilled water in the water bath; The rotary drive mechanism connected to the water bath is started to drive the water bath to rotate back and forth within a certain range, which not only drives the EP tube to rotate along with the rotation of the water bath, forming a mixing action of the EP tube in the first direction, but also makes the distilled water of the set water temperature in the water bath flow, ensuring that the EP tube is in a uniformly heated state; When the water bath reciprocates within a certain range, the ball head seat elastically slidably connected to the outer lower end of the solid rod can be driven to form a sliding tangent fit with the outer top surface of the cylindrical seat, so that the ball head seat can move along the arc shape formed by the outer top surface of the cylindrical seat. The purpose of setting the guide slide groove is to limit the matching path of the arc shape formed by the ball head seat and the outer top surface of the cylindrical seat, thereby driving the solid rod to form a reciprocating rotation within a certain range; The solid rod drives the parallelogram structure composed of the main connecting rod and the connecting rod to form a rotational movement, which can drive the EP tube installed in the pipe sleeve to form a reciprocating rotational mixing movement in the second direction in the water bath. After the water bath is completed, the outer surface of the top end of the conical plug is squeezed inward through the push hole to disengage the conical plug from the conical plug sleeve, and the placement rack and the tube sleeve carrying the EP tube are quickly taken out to enter the subsequent termination reaction step.

[0007] The Chinese herbal medicine molecular identification water bath device of the present invention further comprises a counter-stabilizing component and an outer rotating arm assembly, wherein the counter-stabilizing component comprises an auxiliary fixing frame, an outer sliding seat and a vertical rod, and the outer rotating arm assembly comprises a rotating arm and a release push sleeve; The inner lower end of the auxiliary fixed frame is fixedly connected to the top end of the connecting rod, the outer side surface of the water bath is symmetrically fixedly connected with an outer guide column, the outer end of the outer guide column is fixedly connected with a side seat, and the outer sliding seat is slidably connected to the outer guide column; The vertical poles are fixedly connected to the top of the outer sliding seat in pairs, and a swivel column is rotatably connected in each group of vertical poles. The swivel column is slidably connected to the slide groove provided on the outer side of the upper end of the auxiliary fixed frame. Flexible support seats are provided on the upper and lower sides of the swivel column, and the flexible support seats are fixedly connected to the vertical poles. The two groups of flexible support seats are respectively clamped on the upper and lower sides of the outer body of the auxiliary fixed frame; When the parallelogram structure composed of the connecting rod and the main connecting rod performs a rotational movement, the supporting stability of one end of the connecting rod can be improved by cooperating with the sliding connection of the outer sliding seat and the outer guide column in the first direction, and the sliding connection of the rotating column and the auxiliary fixing frame in the second direction; The rotating arm is screwed to the outer side of the main shell assembly and can rotate automatically. Release electric cylinders are fixedly installed on both sides of the top of the rotating arm. The bottom end of the telescopic rod of the release electric cylinder is fixedly connected to a push seat. The release push sleeve is fixedly connected to the bottom surface of the push seat. The top of the rotating arm is also fixedly connected with a pair of safety sleeves; After the water bath stops rotating to a position where the top end is parallel to the top surface of the main shell assembly, the parallelogram structure composed of the main connecting rod and the connecting rod can be rotated to form a rectangular structure; When the water bath stops rotating to a position where the top end is parallel to the top surface of the main shell assembly, the parallelogram structure composed of the main connecting rod and the connecting rod rotates synchronously to form a rectangular structure. As the rotating arm rotates upward, the safety sleeve can be inserted into the connecting arm of the auxiliary fixing frame. Therefore, after the rotating arm is rotated to a position where the push seat is parallel to the top surface of the main shell assembly, the safety sleeve and the auxiliary fixing frame form a snap fit, and the release push sleeve position is just opposite to the push hole position opened in the placement frame body. After the release electric cylinder is started to drive the push seat and the release push sleeve to move downward , the inner hole of the release push sleeve can be inserted into the outer surface of the tapered plug column extending into the push hole. As the release push sleeve continues to move downward, the tapered plug column can be driven to form an inward contraction movement. After the tapered plug column contracts, the snap-fitting formed by the tapered plug column and the tapered plug sleeve fails, and at this moment, there is enough space between the bottom end of the push seat and the top end of the placement rack. The placement rack can be moved upward a certain distance relative to the main connecting rod, and after the release push sleeve is retracted and the rotating arm rotates outward to a position that does not interfere with the removal of the placement rack, the placement rack carrying the EP tube can be taken out of the water bath.

[0008] By adopting the above technical solution, the present invention can achieve the following beneficial effects: (1) The present invention is based on the rotational connection between the cylindrical hollow structure water bath and the main shell, which can form a state where the water bath reciprocates within a certain range. Since the water bath can contain both distilled water for water bathing and the EP tube, when the water bath reciprocates, it can not only improve the fluidity of the distilled water in the water bath to a certain extent, eliminate the temperature gradient of the distilled water in the water bath, so that the EP tube is evenly heated, but also form a mixing and shaking action for the EP tube, so as to promote the full mixing of the reactants; (2) The present invention further provides a parallelogram structure consisting of a main connecting rod and a connecting rod in the water bath, and connects a placement rack for placing the EP tube to the main connecting rod in a detachable plug-in manner. In addition, a ball head seat is elastically slidably connected to the outer lower end of a fixed rod fixed to the top end of one set of main connecting rod rotation shafts. The ball head seat can not only slide tangentially with the arc surface formed on the outer top surface of the cylindrical seat, but also slide tangentially with the guide groove. When the water bath rotates back and forth within a certain range, the parallelogram structure consisting of the main connecting rod and the connecting rod can form a reciprocating rotational motion, thereby driving the EP tube to move and mix in the distilled water in the water bath, thereby achieving the purpose of multiple improvements in reaction efficiency.

[0014] like Figure 1-Figure 16 As shown, a water bath device for molecular identification of Chinese medicinal materials, the water bath 202 is screwed on the inner top of the main shell component 1, and can reciprocate within a certain range, the top opening of the water bath 202 is always located outside the main shell component 1, the inner side of the water bath 202 is symmetrically screwed with a main connecting rod 303, the connecting rod 304 is screwed between the other ends of the main connecting rod 303, the main connecting rod 303 and the connecting rod 304 form a parallelogram structure, one set of the main connecting rods 303 at the top of the rotating shaft is fixed with a fixed rod 306, the cylindrical seat 307 is fixed to the outer side of the main shell component 1, the other end of the fixed rod 306 is slidably connected with an elastic downward ball head seat 309, the outer top surface of the cylindrical seat 307 is fixed with a guide groove 308, the ball head seat 309 is slidably connected with the outer top surface of the cylindrical seat 307, and the guide groove 308; The inner lower end of the auxiliary fixing frame 401 is fixedly connected to the top of the connecting rod 304, the outer side surface of the water bath 202 is symmetrically fixedly connected with an outer guide column 402, the outer end of the outer guide column 402 is fixedly connected with a side seat 403, and the outer sliding seat 404 is slidably connected to the outer guide column 402; The vertical rods 405 are fixedly connected in pairs to the top of the outer sliding seat 404, and each group of vertical rods 405 is rotatably connected with a swivel column 406, which is slidably connected to the sliding groove provided on the outer side of the upper end of the auxiliary fixed frame 401. Flexible support seats 407 are provided on the upper and lower sides of the swivel column 406, and the flexible support seats 407 are fixedly connected to the vertical rods 405. The two groups of flexible support seats 407 are respectively clamped on the upper and lower sides of the outer body of the auxiliary fixed frame 401, which can improve the reliability of the sliding connection between the swivel column 406 and the auxiliary fixed frame 401. When the parallelogram structure composed of the connecting rod 304 and the main connecting rod 303 performs a rotational movement, the supporting stability of one end of the connecting rod 304 can be improved by cooperating with the sliding connection in the first direction composed of the outer sliding seat 404 and the outer guide column 402, and the sliding connection in the second direction composed of the rotating column 406 and the auxiliary fixing frame 401; A conical plug post 507 is fixed to one side of the top of each set of main connecting rods 303, and a conical plug sleeve 508 is fixed to one side of the placement rack 501. After the other side of the placement rack 501 is slidably inserted with the other side of the main connecting rod 303, the conical plug sleeve 508 can be snap-fitted with the conical plug post 507; The pipe sleeves 504 are arranged and fixedly connected to the placement rack 501. The EP pipe 506 can be inserted and installed in each set of pipe sleeves 504. The push hole 509 is set in the main body of the placement rack 501 at a position directly opposite to the conical plug sleeve 508. After the conical plug sleeve 508 and the conical plug post 507 are snap-fitted into place, the top outer surface of the conical plug post 507 can be squeezed inward through the push hole 509, so that the conical plug post 507 is separated from the snap-fitting with the conical plug sleeve 508. Here’s how it works: EP tube 506 is used to hold the DNA sample of Chinese medicinal materials and is tightly sealed to prevent contamination; The water bath 202 is used to hold distilled water, and the distilled water is heated to a set temperature by a heating mechanism. The purpose of adding distilled water is to prevent scaling; After the set water temperature of the distilled water in the water bath 202 is stabilized, the EP tube 506 containing the Chinese medicinal material DNA sample is inserted and installed into the tube sleeve 504 in place while the placement rack 501 is plugged and connected to the main connecting rod 303, and the EP tube 506 is immersed in the distilled water in the water bath 202; The rotating drive mechanism connected to the water bath 202 is started to drive the water bath 202 to reciprocate within a certain range. Since the main connecting rod 303 is installed inside the water bath 202, the placement frame 501 is plug-connected with the main connecting rod 303, and the EP tube 506 is plug-connected and installed in the pipe sleeve 504, when the water bath 202 reciprocates within a certain range, it can not only drive the EP tube 506 to rotate with the rotation of the water bath 202, forming a mixing action of the EP tube 506 in the first direction, but also make the distilled water of the set water temperature in the water bath 202 in a flowing state, ensuring that the EP tube 506 is in a uniformly heated state; When the water bath 202 reciprocates within a certain range, the ball head seat 309 elastically slidably connected to the outer lower end of the fixed rod 306 can be driven to form a sliding tangent fit with the outer top surface of the cylindrical seat 307, so that the ball head seat 309 can move along the arc shape formed on the outer top surface of the cylindrical seat 307. The purpose of setting the guide groove 308 is to limit the matching path of the arc shape formed by the ball head seat 309 and the outer top surface of the cylindrical seat 307, so that within the range of the sliding tangent fit between the ball head seat 309 and the ball head seat 309, the ball head seat 309 can safely and maintain a certain path to form a sliding tangent fit with the arc shape formed on the outer top surface of the cylindrical seat 307, thereby driving the fixed rod 306 to form a reciprocating rotation within a certain range; The fixed rod 306 drives the parallelogram structure composed of the main connecting rod 303 and the connecting rod 304 to form a rotational movement, which can drive the EP tube 506 inserted and installed in the tube sleeve 504 to form a reciprocating rotational mixing action in the second direction in the water bath 202, thereby improving the efficiency of lysis. After the water bath is completed, the outer surface of the top end of the conical plug 507 is squeezed inward through the push hole 509, so that the conical plug 507 and the conical plug sleeve 508 are disengaged from the snap fit, and the placement rack 501 and the tube sleeve 504 carrying the EP tube 506 are quickly taken out to enter the subsequent termination reaction step.

The photoelectric sensor transmitting module 216 is fixedly installed on the outer end of one group of eccentric columns 214, and the photoelectric sensor receiving module 215 is fixedly installed on the inner top surface of the main shell 101.

The outward-moving socket 510 is fixedly installed in the middle of the top of the placement rack 501. Not only are there teeth on the outside of the conical pin 507 and the inside of the conical sleeve 508 that fit together, but there are also cross-shaped grooves in the bodies of the conical pin 507 and the conical sleeve 508 to facilitate elastic insertion of the conical sleeve 508 and the conical pin 507.

[0017] The specific structure of the outer swing arm assembly 6 and the outer moving plug assembly 7 is as follows: Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, the rotary arm fixing seat 601 is fixedly connected to the outer side of the main housing 101, and the bottom end of the rotary arm 602 is rotatably connected to the rotary arm fixing seat 601; The middle part of the main body of the rotating arm 602 is laterally fixedly connected with a moving shaft 603, the outer side of the main housing 101 is fixedly connected with an electric cylinder fixed rotating seat 604, the bottom end of the main body of the servo electric cylinder 605 is rotatably connected to the electric cylinder fixed rotating seat 604, and the top end of the telescopic rod of the servo electric cylinder 605 is rotatably connected to the moving shaft 603; The telescopic rod of the servo electric cylinder 605 can move within the telescopic range with high precision, thereby controlling the rotating arm 602 to form different rotation states; Release electric cylinders 607 are fixedly installed on both sides of the top of the rotating arm 602, the bottom end of the telescopic rod of the release electric cylinder 607 is fixedly connected to a push seat 608, and the release push sleeve 609 is fixedly connected to the bottom surface of the push seat 608; The top of the rotating arm 602 is also fixedly connected with a pair of safety sleeves 606; After the water bath 202 stops rotating to a position where the top end is parallel to the top surface of the main housing 101, the parallelogram structure formed by the main connecting rod 303 and the connecting rod 304 can be rotated to form a rectangular structure; When the water bath 202 stops rotating to a position where the top end is parallel to the top surface of the main housing 101, the parallelogram structure composed of the main connecting rod 303 and the connecting connecting rod 304 is synchronously rotated to form a rectangular structure. As the rotating arm 602 rotates upward, the safety sleeve 606 can be inserted into the connecting arm of the auxiliary fixing frame 401. After the rotating arm 602 is rotated to a position where the push seat 608 is parallel to the top surface of the main housing 101, the safety sleeve 606 and the auxiliary fixing frame 401 form a snap fit, thereby improving the stability of the rectangular structure composed of the main connecting rod 303 and the connecting connecting rod 304. After the rotating arm 602 rotates to a position where the push seat 608 is parallel to the top surface of the main shell 101, the position of the release push sleeve 609 is just opposite to the position of the push hole 509 opened in the main body of the placement rack 501. After the release electric cylinder 607 is started to drive the push seat 608 and the release push sleeve 609 to move downward, the inner hole of the release push sleeve 609 can be inserted into the outer surface of the tapered plug post 507 extending into the push hole 509. As the release push sleeve 609 continues to move downward, the tapered plug post 507 can be driven to form a Inward contraction action, after the conical plug post 507 contracts, the snap fit formed by the conical plug post 507 and the conical plug sleeve 508 fails, and at this moment, there is enough space between the bottom end of the push seat 608 and the top end of the placement rack 501, so that the placement rack 501 can be moved upwards for a distance relative to the main connecting rod 303, and after the push sleeve 609 is released and retracted, and the rotating arm 602 is rotated outwards to a position that does not interfere with the removal of the placement rack 501, the placement rack 501 carrying the EP tube 506 is quickly taken out of the water bath 202; The U-shaped slides 701 are fixedly connected in pairs to the top of the rotating arm 602, and both sides of the bottom of the U-shaped slides 701 are slidably connected with plug-in columns 702, and the plug-in column side plates 703 are fixedly connected between the outer sides of the plug-in columns 702; One side of each group of push seats 608 is fixedly connected with a push inclined block 707, and one side of the plug column side plate 703 is fixedly connected with a pair of passive inclined blocks 706, and the push inclined blocks 707 on the same side are directly opposite to the passive inclined blocks 706; The sleeve 704 is plugged and fixed to the middle of the plug-in column 702. A compression spring 705 is sleeved and installed in each group of plug-in columns 702. One side of the compression spring 705 is fixed to the sleeve 704, and the other side is fixed to the bottom end of a group of U-shaped slide seats 701 at the inner end of the top head of the rotating arm 602. Under the support of the compression spring 705, when there is no external force pushing the plug side plate 703, the sleeve 704 is in a state of being clamped with the bottom end of a group of U-shaped slide seats 701 at the outer end of the top head of the rotating arm 602, and the passive inclined block 706 is in an extreme position of outward movement; After the rotating arm 602 rotates to the position where the push seat 608 is parallel to the top surface of the main housing 101, the plug-in column 702 is horizontally located opposite to the outward-moving plug-in seat 510. As the release electric cylinder 607 drives the push seat 608 and the release push sleeve 609 to move downward, after the push seat 608 moves downward to a certain position, the push inclined block 707 and the passive inclined block 706 form a sliding tangential fit, and in the process of the push seat 608 and the release push sleeve 609 continuing to move downward, the plug-in column 702 can be pushed to be inserted into the outward-moving plug-in seat 510; After the release push sleeve 609 is moved downward to a position where the conical plug post 507 and the conical plug sleeve 508 can be safely pushed out of engagement, the plug post 702 has been inserted into the outwardly movable plug seat 510 and is in place; At this moment, the release push sleeve 609 passes through the push hole 509 and is in an inwardly squeezing state on the conical plug post 507, and the conical plug post 507 is separated from the conical plug sleeve 508. In the process of the rotating arm 602 automatically rotating outward to drive the plug post 702 to move, the conical plug sleeve 508 will not interfere with the conical plug post 507, and will use the plug-in cooperation formed by the plug post 702 and the outward-moving plug seat 510 to take the placement rack 501 carrying the EP tube 506 out of the water bath 202. Due to the elastic deformation of the conical plug post 507 itself, the release push sleeve 609 and the conical plug post 507 can be safely removed in this process. There is a certain fitting clearance between the arc socket 502 and the arc slot 503, which allows the rotating arm 602 to automatically rotate outward through the plug-in fit formed by the plug-in column 702 and the outward-moving plug-in seat 510 to disengage the placement rack 501 from the main connecting rod 303 and safely remove it from the water bath 202, reducing the risk of burns during operation.
