[0027] To this end, the embodiment of the present application designs a setting that the carrier 2 for carrying the chip assembly 3 is movable along the horizontal direction, and a biological detection device 100 that the carrier 2 and the chip assembly 3 are separated from the heating module 4 without heating, so that the placing and taking out of the chip assembly 3 can be completed outside the biological detection device 100, the possibility of sample contamination is reduced, the high temperature inside the biological detection device 100 avoids causing harm to human hands, the reliability and safety of the biological detection device 100 are improved, and the movement of the carrier 2 is avoided from being affected by the heating module 4, the heating module 4 does not need to move together with the carrier 2, the structure of the biological detection device 100 is simplified, and the taking out and placing of the chip assembly 3 are more convenient.

[0028] The following refers to Figures 1-5 The biological detection device 100 according to the embodiment of the present application is described.

[0029] The biological detection device 100 according to the embodiment of the present application can include a mounting bracket 1, a carrier 2, a heating module 4, a conveying assembly 5, and a pressing plate 6.

[0030] The mounting bracket 1 serves to support the entire biological detection device 100, ensuring the stability of the overall structure of the biological detection device 100, and the chip assembly 3 is used to store samples and needs to be replaced after a group of detections are completed.

[0031] The carrier 2 is used to carry the chip assembly 3, and the chip assembly 3 can move together with the movement of the carrier 2. The carrier 2 is movably arranged along the horizontal direction in the mounting bracket 1, so that the carrier 2 can be moved to a sample adding position outside the biological detection device 100 along the horizontal direction. The user can conveniently replace the chip assembly 3 carried by the carrier 2 at the sample adding position, the possibility of sample contamination is reduced, the high temperature inside the biological detection device 100 avoids causing harm to human hands, and the reliability and safety of the biological detection device 100 are improved.

[0032] After the sample adding is completed, the carrier 2 can be moved to a detection position inside the biological detection device 100 along the horizontal direction, and the heating and detection of the sample on the chip assembly 3 are completed at the detection position.

[0033] The heating module 4 is arranged below the carrier 2 and is used to heat the chip assembly 3 and further heat the sample in the chip assembly 3. A first elastic member is arranged between the carrier 2 and the mounting bracket 1 and is used to drive the carrier 2 to move upwards to avoid the carrier 2 from the heating module 4, that is, the first elastic member can always support the carrier 2 to avoid the heating module 4 without external force.

[0034] Thus, during the horizontal movement of the bracket 2 and the chip assembly 3, no external force acts in the vertical direction at all times, the first elastic member can always support the bracket 2 to avoid the heating module 4, the heating module 4 is separately arranged from the chip assembly 3 and the bracket 2, thereby avoiding the influence of the heating module 4 on the movement of the bracket 2, and the heating module 4 does not need to move together with the bracket 2, thereby simplifying the structure of the biological detection device 100, making the chip assembly 3 easier to take out and place, and avoiding the high temperature of the heating module 4 from causing harm to the human hand during the taking out and placing of the chip assembly 3, thereby improving the safety of the biological detection device 100.

[0035] The conveying assembly 5 can be used to interface with the chip assembly 3 to convey medium to the chip assembly 3 to realize droplet generation. The conveying assembly 5 is movably arranged on the mounting bracket 1 in the up-down direction, after the bracket 2 moves to the detection position inside the biological detection device 100 in the horizontal direction, the conveying assembly 5 moves downward until it interfaces with the chip assembly 3, and after the interface is completed, the conveying assembly 5 is suitable for conveying medium to the chip assembly 3, after the medium conveying is completed, the conveying assembly 5 can move upward to separate the conveying assembly 5 from the chip assembly 3, and the conveying assembly 5 can be repeatedly used during the detection process.

[0036] Since a certain pressure is generated between the conveying assembly 5 and the chip assembly 3 during the downward movement of the conveying assembly 5, the sealing of the air path between the conveying assembly 5 and the chip assembly 3 can be better achieved.

[0037] Further, the pressing plate 6 is connected with the conveying assembly 5 to move together with the conveying assembly 5, specifically, in the state that the bracket 2 moves to the detection position directly below the pressing plate 6, the pressing plate 6 is suitable for driving the bracket 2 to move downward under the driving of the conveying assembly 5 to make the chip assembly 3 adhere to the heating module 4. The pressing plate 6 can uniformly apply force to the bracket 2 to drive the bracket 2 and the chip assembly 3 arranged on the bracket 2 to move downward until the chip assembly 3 adheres to the heating module 4, thereby ensuring that the heating module 4 can heat the sample in the chip assembly 3 during the detection process, and during the downward movement of the bracket 2, the first elastic member is compressed, and the first elastic member accumulates elastic potential energy.

[0038] After the heating process is completed, the pressing plate 6 is suitable for moving together with the conveying assembly 5 in a direction away from the bracket 2 and the chip assembly 3, at this time, the upper part of the bracket 2 and the chip assembly 3 loses the limiting of the pressing plate 6, and the accumulated elastic potential energy in the first elastic member can drive the bracket 2 to move upward to make the bracket 2 avoid the heating module 4, and the bracket 2 can move freely in the horizontal direction, thereby avoiding the influence of the heating module 4 on the movement of the bracket 2, and the heating module 4 does not need to move together with the bracket 2, thereby simplifying the structure of the biological detection device 100, and making the chip assembly 3 easier to take out and place.

[0039] Further, since the pressing plate 6 is connected with the conveying assembly 5 to move together with the conveying assembly 5, thus, the up-down movement of the pressing plate 6 and the conveying assembly 5 only needs one driving assembly 11 to complete the driving, which simplifies the structure of the biological detection device 100 and reduces the production cost of the biological detection device 100.

[0040] According to the biological detection device 100 of the embodiment of the present application, the placing and taking out of the chip assembly 3 can be completed outside the biological detection device 100, which reduces the possibility of sample contamination, avoids high-temperature injury, has higher reliability and better safety.

[0041] As shown in Figures 1-2 , the biological detection device 100 further comprises a driving assembly 11 arranged on the mounting bracket 1 and connected with the conveying assembly 5, which is used to drive the conveying assembly 5 to move in the up-down direction. Through one driving assembly 11, the up-down movement of the conveying assembly 5 and the pressing plate 6 can be simultaneously realized, and the purpose of indirectly driving the bracket 2 and the chip assembly 3 to move downward can be achieved, the overall structure of the biological detection device 100 is simplified, and the production cost of the biological detection device 100 is reduced.

[0042] Referring to Figure 2 , the biological detection device 100 further comprises a mounting seat 9 arranged below the bracket 2 and moving synchronously with the bracket 2 in the horizontal direction, and a first elastic member arranged between the mounting seat 9 and the bracket 2.

[0043] That is to say, the mounting seat 9 is movably arranged on the mounting bracket 1 in the horizontal direction, and the bracket 2 is connected with the mounting seat 9 through the first elastic member, so that the bracket 2 can move up-down relative to the mounting seat 9 and the mounting bracket 1.

[0044] The bracket 2 and the mounting seat 9 can move together in the horizontal direction to a sample adding position outside the biological detection device 100, at which the user can conveniently replace the chip assembly 3 carried on the bracket 2, which reduces the possibility of sample contamination, avoids the high temperature inside the detection device from causing injury to the human hand, and improves the reliability and safety of the biological detection device 100.

[0045] After the sample adding is completed, the bracket 2 and the spring seat can move in the horizontal direction to a detection position inside the biological detection device 100, and the heating and detection of the sample on the chip assembly 3 can be completed at the detection position.

[0046] At the detection position, the conveying assembly 5 is located above the detection position and is movably arranged on the mounting bracket 1 in the up-down direction, the pressing plate 6 is connected with the conveying assembly 5 to move together with the conveying assembly 5, in the state that the bracket 2 moves to the detection position directly below the pressing plate 6, the driving assembly 11 is suitable for driving the pressing plate 6 and the conveying assembly 5 at the same time, the pressing plate 6 is suitable for driving the bracket 2 to move downward to make the chip assembly 3 adhere to the heating module 4 under the driving of the conveying assembly 5, in the process of the downward movement of the bracket 2, the first elastic member between the mounting seat 9 and the bracket 2 is compressed, and the first elastic member accumulates elastic potential energy.

[0047] After the heating process is completed, the pressing plate 6 is suitable for moving together with the conveying assembly 5 to the direction away from the bracket 2 and the chip assembly 3 under the driving of the conveying assembly 5, at this time, the upper part of the bracket 2 and the chip assembly 3 loses the limit of the pressing plate 6, and the elastic potential energy accumulated in the first elastic member can drive the bracket 2 to move upward to make the bracket 2 avoid the heating module 4.

[0048] Referring to Figure 2 , the first elastic member is a first spring 7, one of the mounting seat 9 and the bracket 2 is provided with a first guide column extending in the up-down direction, and the other is provided with a first guide hole, the first guide column and the first guide hole are in sliding fit, and the first spring 7 is sleeved on the first guide column.

[0049] The cooperation of the first guide column and the first guide hole not only can guide the up-down movement of the bracket 2, ensure the stable movement of the bracket 2 in the up-down direction, but also can connect the mounting seat 9 and the bracket 2, ensure the stability of the connection between the mounting seat 9 and the bracket 2.

[0050] In some embodiments, the first guide column is provided with a first limiting member, the first limiting member can limit the movement of the bracket 2 in the up-down direction, and avoid the bracket 2 from moving too much in the up-down direction and separating from the mounting seat 9.

[0051] As shown in Figure 1 and Figure 2 , the mounting bracket 1 is provided with at least two spaced-apart slide rails 12, and each slide rail 12 extends in the horizontal direction, the side wall of the mounting seat 9 is provided with a sliding block 91, and the sliding block 91 and the slide rail 12 are in sliding fit. The slide rail 12 can play a guiding role in the horizontal movement of the bracket 2 and the mounting seat 9, ensure the smooth movement of the bracket 2 and the mounting seat 9 in the horizontal direction, and ensure the stability of the bracket 2 during movement.

[0052] The bracket 2 is located between the two slide rails 12, and the slide rails 12 can support the bracket 2 on both sides of the bracket 2, and ensure the stability of the bracket 2.

[0053] Referring to Figure 1 and Figure 2The conveying assembly 5 comprises a plurality of output portions 51, and the chip assembly 3 comprises a plurality of matching portions 31, the plurality of output portions 51 are adapted to be matched with the plurality of matching portions 31 one by one, so that the synchronous detection of multiple groups of chips can be realized at the same time.

[0054] In combination Figures 3-5 In the embodiment shown, the pressing plate 6 is provided with a avoiding hole 61, and the output portion 51 is adapted to pass through the avoiding hole 61 to match with the matching portion 31, so as to avoid the influence of the arrangement of the pressing plate 6 on the normal docking of the output portion 51 and the matching portion 31.

[0055] In addition, the avoiding hole 61 arranged on the pressing plate 6 can limit the output portion 51, ensure the stability of the arrangement position of the output portion 51, and ensure that the output portion 51 and the matching portion 31 can be stably docked. Further, when relative movement occurs between the output portion 51 and the pressing plate 6, the avoiding portion can also guide the relative movement between the pressing plate 6 and the output portion 51, and ensure the stability of the movement of the pressing plate 6.

[0056] As Figures 1-5 shown, the conveying assembly 5 further comprises a mounting plate 52, which is arranged above the pressing plate 6, and the plurality of output portions 51 are fixed to the mounting plate 52. The mounting plate 52 can fix the output portion 51, ensure the stability of the arrangement position of the output portion 51, and ensure that the output portion 51 and the matching portion 31 can be stably docked.

[0057] The second elastic member is arranged between the pressing plate 6 and the mounting plate 52, and is used to drive the pressing plate 6 to move downward relative to the mounting plate 52. Thus, the pressing plate 6 and the output portion 51 fixedly connected with the mounting plate 52 can move asynchronously, and the output portion 51 can move away from the chip assembly 3 after the conveying of the medium is completed. At this time, the pressing plate 6 can remain at the original position to limit the bracket 2, and ensure that the chip assembly 3 and the heating module 4 remain in contact. Thus, during the heating of the chip assembly 3, the output portion 51 and the chip assembly 3 are separated, which can reduce the pollution of the output portion 51 to the sample in the chip assembly 3.

[0058] In some embodiments, when the output assembly is docked with the chip assembly 3, the elastic force of the second elastic member is greater than the elastic force of the first elastic member. After the mounting plate 52 moves away from the pressing plate 6 by a certain distance in this state, the elastic force of the second elastic member is still greater than or equal to the elastic force of the first elastic member. The pressing plate 6 can remain at the original position to limit the bracket 2, and ensure that the chip assembly 3 and the heating module 4 remain in contact. The elastic force of the second elastic member being greater than the elastic force of the first elastic member can also better realize the sealing of the air path between the conveying assembly 5 and the chip assembly 3.

[0059] Referring to Figure 2The second elastic member is a second spring 8, one of the pressing plate 6 and the mounting plate 52 is provided with a second guide column 81 extending in the up-down direction, and the other is provided with a second guide hole, the second guide column 81 and the second guide hole are in sliding fit, and the second spring 8 is sleeved on the second guide column 81.

[0060] The cooperation of the second guide column 81 and the second guide hole not only can guide the up-down movement of the pressing plate 6 relative to the conveying assembly 5, but also can connect the pressing plate 6 and the mounting plate 52, and ensure the stability of the connection between the pressing plate 6 and the mounting plate 52.

[0061] In some embodiments, the second guide column 81 is provided with a second limiting member, which can limit the pressing plate 6 and avoid the pressing plate 6 from being separated from the mounting plate 52.

[0062] Specifically, in combination with Figures 1-5 The specific operation process of the biological detection device 100 is described.

[0063] The bracket 2 and the mounting seat 9 can be moved together in the horizontal direction to a sample adding position outside the biological detection device 100, and the user can conveniently replace the chip assembly 3 carried on the bracket 2 at the sample adding position, which reduces the possibility of sample contamination and avoids the high temperature inside the detection device from causing harm to the human hand, thereby improving the reliability and safety of the biological detection device 100.

[0064] After the sample adding is completed, the bracket 2 and the spring seat can be moved in the horizontal direction to a detection position inside the biological detection device 100, and the heating and detection of the sample on the chip assembly 3 can be completed at the detection position.

[0065] At the detection position, the conveying assembly 5 is located above the detection position and is movably arranged on the mounting bracket 1 in the up-down direction, and the conveying assembly 5 comprises a mounting plate 52 and a plurality of output portions 51, the plurality of output portions 51 are fixed to the mounting plate 52, the mounting plate 52 is arranged above the pressing plate 6, and a second elastic member is arranged between the pressing plate 6 and the mounting plate 52.

[0066] The pressing plate 6 and the mounting plate 52 are connected through the second elastic member, and the second elastic member is used to drive the pressing plate 6 to move downward relative to the mounting plate 52.

[0067] In the state that the bracket 2 moves to the detection position directly below the pressing plate 6, the driving assembly 11 is adapted to simultaneously drive the mounting plate 52, the output portion 51 and the pressing plate 6 until the pressing plate 6 contacts the chip assembly 3.

[0068] After the pressure plate 6 contacts the chip assembly 3, the distance between the pressure plate 6 and the mounting plate 52 decreases, the second elastic element is compressed, and the elastic force of the second elastic element provides a downward force to the pressure plate 6, thereby driving the chip assembly 3 and the bracket 2 to move downward. At the same time, the first elastic element is compressed until the chip assembly 3 contacts the heating module 4.

[0069] like Figure 4 As shown, after the chip assembly 3 comes into contact with the heating module 4, the pressure plate 6, the chip assembly 3 and the bracket 2 are limited by the heating module 4. The length of the first elastic member remains unchanged. The driving component 11 drives the mounting plate 52 and the output part 51 to continue to move downward. The second elastic member is further compressed until the output part 51 docks with the mating part 31 on the chip assembly 3. The output part 51 delivers the medium to the chip assembly 3 to realize the generation of droplets.

[0070] Reference Figure 5 After the medium is conveyed, since the elastic force of the second elastic element is greater than that of the first elastic element, the drive assembly 11 is adapted to drive the mounting plate 52 and the output part 51 to move upward a certain distance, so that the output part 51 separates from the mating part 31, and keeps the positions of the pressure plate 6, chip assembly 3 and bracket 2 unchanged. The pressure plate 6 can keep in place to limit the bracket 2, ensuring that the chip assembly 3 remains in contact with the heating module 4. After the output part 51 separates from the mating part 31, the heating module 4 is activated to heat the chip assembly 3.

[0071] After the heating process is completed, the drive assembly 11 is adapted to drive the mounting plate 52 and the output part 51 to continue to move upward. The pressure plate 6 is adapted to move together away from the bracket 2 and the chip assembly 3 under the drive of the mounting plate 52. At this time, the bracket 2 and the chip assembly 3 lose the restriction of the pressure plate 6 above. The elastic potential energy stored in the first elastic member can drive the bracket 2 to move upward so that the bracket 2 avoids the heating module 4.
