[0048] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and understanding the present invention, and are not used to limit the present invention.

[0049] The temperature control device of the sample detection device of the present invention will be described below with reference to the accompanying drawings.

[0050] As Figures 1 to 7As shown in the figure, the present utility model provides a temperature control device for a sample detection device. The temperature control device of the sample detection device includes a housing 10 and a temperature control mechanism. An insertion opening 11 for the reaction tube 200 to extend into is formed on the housing 10. The temperature control mechanism includes a temperature control component 20 and a pushing module 30. The temperature control component 20 includes a heating sheet 21 and two heat conduction blocks 22 spaced apart in the housing 10. An insertion gap 23 communicating with the insertion opening 11 is formed between the two heat conduction blocks 22. And a heating sheet 21 is provided on one side of each heat conduction block 22 facing the insertion gap 23. The pushing module 30 is used to drive the two heat conduction blocks 22 to move towards each other to a fitting position and move away from each other to an avoidance position. It should be noted that the temperature control device of the embodiment of the present utility model can be applied to a sample detection device to heat and cool the reaction tube 200 containing the sample to be detected multiple times, realizing the cyclic heating and cooling of the sample to be detected, so that the target nucleic acid in the sample to be detected is amplified.

[0051] Specifically, the temperature control device includes a pushing module 30, a housing 10, and a temperature control component 20 provided in the housing 10. The temperature control component 20 includes two heat conduction blocks 22 spaced apart. An insertion gap 23 is formed between the two heat conduction blocks 22. And the temperature control component 20 further includes a heating sheet 21. The number of heating sheets 21 is the same as that of the heat conduction blocks 22 and they are respectively provided on one side of the heat conduction blocks 22 facing the insertion gap 23. An insertion opening 11 is formed on the housing 10, and the insertion opening 11 communicates with the insertion gap 23. The pushing module 30 is respectively drivingly connected to the two heat conduction blocks 22. When the reaction tube 200 containing the sample to be detected is inserted into the insertion gap 23 from the insertion opening 11, the pushing module 30 drives the two heat conduction blocks 22 to move away from each other to an avoidance position for avoiding the reaction tube 200. The insertion gap 23 between the two heat conduction blocks 22 increases, so that the reaction tube 200 will not rub against the heating sheet 21 during the process of extending into the insertion gap 23, prolonging the service life of the heating sheet 21 and greatly reducing the maintenance and replacement frequency of the heating sheet 21.

[0052] Further, when the reaction tube 200 is inserted in place, the pushing module 30 drives the two heat conduction blocks 22 to move towards each other to a fitting position. The insertion gap 23 between the two heat conduction blocks 22 decreases, so that the two heating sheets 21 are respectively attached to both sides of the reaction tube 200 to heat the reaction tube 200. And the heat generated by the heating sheet 21 can be quickly conducted to the heat conduction blocks 22 after heating to cool the reaction tube 200, realizing the cyclic heating and cooling of the sample to be detected in the reaction tube 200.

[0053] In the embodiment of the present utility model, the pushing module 30 includes a pushing block 31 and a pushing component 32. The pushing block 31 is slidably disposed in the insertion gap 23. A guiding wall 221 is formed on one side of the heat conducting block 22 facing the insertion gap 23. The guiding wall 221 is inclined towards the insertion gap 23 along the length direction of the heat conducting block 22. The pushing component 32 is drivingly connected to the pushing block 31 and is used to drive the pushing block 31 to slide along the extending direction of the guiding wall 221, so that the pushing block 31 pushes the two heat conducting blocks 22 to move away from each other.

[0054] As Figures 1 to 7 shown, the two heat conducting blocks 22 are arranged at intervals in the housing 10 in the up-down direction. A guiding wall 221 extending in the left-right direction is formed on one side of the heat conducting block 22 facing the insertion gap 23, and the guiding wall 221 is inclined from top to bottom or from bottom to top in the left-right direction. The pushing block 31 is installed in the insertion gap 23 and can slide along the extending direction of the guiding wall 221. The pushing component 32 is drivingly connected to the pushing block 31 and is used to drive the pushing block 31 to slide. When the reaction tube 200 containing the sample to be measured is inserted into the insertion gap 23 from the socket 11, the pushing component 32 drives the pushing block 31 to slide from the left end to the right end of the guiding wall 221, so that the pushing block 31 pushes the two heat conducting blocks 22 to move away from each other to the avoidance position for avoiding the reaction tube 200. The insertion gap 23 between the two heat conducting blocks 22 is increased, effectively preventing the reaction tube 200 from rubbing against the heating sheet 21 and prolonging the service life of the heating sheet 21.

[0055] Further, the heating sheet 21 is arranged corresponding to the socket 11. The guiding wall 221 and the heating sheet 21 are arranged at intervals along the length direction of the heat conducting block 22 and are located at one end of the heating sheet 21. When the reaction tube 200 extends from the socket 11 between the two heating sheets 21, the pushing component 32 drives the pushing block 31 to slide from the right end to the left end of the guiding wall 221, so that the two heat conducting blocks 22 move towards each other to the fitting position where the two heating sheets 21 are respectively attached to both sides of the reaction tube 200. The heating sheet 21 can generate heat to heat the reaction tube 200, so as to perform a cyclic process of multiple temperature rises and falls on the sample to be measured in the reaction tube 200.

[0056] In the embodiment of the present utility model, the temperature control device further includes a reset component 40. The reset component 40 includes a first mounting rod 41 and a first spring 42. A first mounting groove 222 is formed on the side of the heat conducting block 22 facing away from the guiding wall 221. The first mounting rod 41 is arranged on the housing 10 and extends into the first mounting groove 222. The first spring 42 is sleeved on the first mounting rod 41, and the two ends of the first spring 42 are respectively abutted against the housing 10 and the heat conducting block 22 in one-to-one correspondence.

[0057] As Figures 1 to 7As shown, one end of the first mounting rod 41 is connected to the housing 10, and the other end of the first mounting rod 41 extends into the first mounting groove 222. The first spring 42 is sleeved on the first mounting rod 41. One end of the first spring 42 abuts against the housing 10, and the other end of the first spring 42 abuts against the heat conducting block 22. When the pushing assembly 32 drives the pushing block 31 to push the two heat conducting blocks 22 to move away from each other, the heat conducting block 22 and the housing 10 cooperate to squeeze the first spring 42. When the reaction tube 200 extends between the two heating sheets 21, the pushing assembly 32 drives the pushing block 31 to slide leftward along the guiding wall 221. The elastic restoring force of the first spring 42 acts on the heat conducting block 22, so that the two heat conducting blocks 22 move toward each other to the fitting position to facilitate heating the reaction tube 200. Moreover, the elastic restoring force of the first spring 42 can also act on the heating sheet 21 through the heat conducting block 22, so that the heating sheet 21 moves into the insertion gap 23 to press the reaction tube 200, improving the heat uniformity of the reaction tube 200 and accelerating the heating rate. Also, the first mounting rod 41 can adopt fasteners such as screws and pins in the prior art, which is convenient for installation and reduces the cost.

[0058] Furthermore, the reset assembly 40 further includes a second mounting rod 43 and a second spring 44. The housing 10 is provided with a mounting ear 12. A second mounting groove 311 is formed in the pushing block 31 along the length direction of the heat conducting block 22. The second mounting rod 43 is arranged on the mounting ear 12 and extends into the second mounting groove 311. The second spring 44 is sleeved on the second mounting rod 43, and the two ends of the second spring 44 respectively abut against the mounting ear 12 and the pushing block 31 in one-to-one correspondence.

[0059] As Figures 3 to 8 shown, the housing 10 is provided with a mounting ear 12 extending toward the inside of the housing 10, and the mounting ear 12 and the heat conducting block 22 are arranged at intervals in the left-right direction. A second mounting groove 311 extending in the left-right direction is formed at the position corresponding to the mounting ear 12 on the pushing block 31. One end of the second mounting rod 43 is connected to the mounting ear 12, and the other end of the second mounting rod 43 extends into the second mounting groove 311. The second spring 44 is sleeved on the second mounting rod 43. One end of the second spring 44 abuts against the mounting ear 12, and the other end of the second spring 44 abuts against the bottom wall of the second mounting groove 311. When the pushing assembly 32 drives the pushing block 31 to slide rightward along the guiding wall 221, the pushing block 31 and the mounting ear 12 cooperate to squeeze the second spring 44. When the reaction tube 200 extends between the two heating sheets 21, the pushing assembly 32 drives the pushing block 31 to slide leftward along the guiding wall 221. The elastic restoring force of the second spring 44 acts on the pushing block 31, enabling the pushing block 31 to quickly reset and improving the smoothness of the reset sliding of the pushing block 31.

[0060] In an embodiment of the present utility model, the pushing assembly 32 includes a sliding plate 321 and a push rod 322. The pushing block 31 is arranged on the sliding plate 321, and the push rod 322 is arranged on the side of the sliding plate 321 facing away from the pushing block 31. A sliding groove 13 is formed on the housing 10, and the push rod 322 is slidably inserted through the sliding groove 13. As Figures 1 to 5 shown, a pushing block 31 is arranged on one side of the sliding plate 321. The pushing block 31 extends into the insertion gap 23 and is in sliding fit with the guiding wall 221. The push rod 322 is arranged on the other side of the sliding plate 321 and passes through the sliding groove 13 on the housing 10 and extends out of the housing 10. The sliding groove 13 extends along the length direction of the heat conducting block 22. By pushing the push rod 322 from left to right along the extending direction of the sliding groove 13, the push rod 322 drives the pushing block 31 to slide from the left end to the right end of the guiding wall 221 through the sliding plate 321, so that the pushing block 31 pushes the two heat conducting blocks 22 to move away from each other to the avoidance position to prevent the reaction tube 200 from extending in and causing wear to the heating sheet 21; and, by pulling the push rod 322 from right to left along the extending direction of the sliding groove 13, the push rod 322 drives the pushing block 31 to slide from the right end to the left end of the guiding wall 221 through the sliding plate 321, so that the two heat conducting blocks 22 move towards each other to the fitting position under the elastic restoring force of the corresponding first springs 42 respectively, and the heating sheet 21 is attached to and presses the reaction tube 200 to improve the heat reception uniformity and the temperature rising effect.

[0061] In an embodiment of the present utility model, the number of the pushing blocks 31 is set to be multiple. The multiple pushing blocks 31 are arranged at intervals on the sliding plate 321, and guiding walls 221 are formed at positions corresponding to each pushing block 31 on the heat conducting block 22. As Figures 4 to 8 shown, two pushing blocks 31 arranged at intervals in the left - right direction are arranged on the side of the sliding plate 321 facing the inside of the housing 10. Guiding walls 221 are arranged at positions corresponding to each pushing block 31 on each heat conducting block 22, so that by pushing and pulling the sliding plate 321, the two pushing blocks 31 can be driven to slide synchronously along the corresponding guiding walls 221, thereby improving the smoothness and stability of the movement of the two heat conducting blocks 22 towards or away from each other. And, the two pushing blocks 31 are respectively arranged at both ends of the heating sheet 21, so that the two pushing blocks 31 respectively support at the left and right ends of each heat conducting block 22, the structure is stable and reliable, and the movement smoothness of the heat conducting block 22 is improved.

[0062] In another embodiment of the present utility model, the pushing assembly 32 includes a sliding plate 321 and a driving member 323. The pushing block 31 is arranged on the sliding plate 321, and the pushing assembly 32 further includes a driving member 323. The driving member 323 is drivingly connected to the pushing block 31. As Figure 6 and Figure 7As shown, the driving end of the driving member 323 is drivingly connected to the pushing block 31. The driving member 323 is used to drive the pushing block 31 to slide along the length direction of the heat conducting block 22, so that the two heat conducting blocks 22 move away from each other to the avoidance position or move towards each other to the fitting position. There is no need for manual operation, the degree of automation is high, and it effectively prevents the heating sheet 21 from being worn when the reaction tube 200 is inserted. Moreover, the driving member 323 can adopt driving members such as motors, cylinders, and electric cylinders in the prior art that can drive the pushing block 31 to slide in the left-right direction, so that the driving member 323 can drive the two pushing blocks 31 to slide synchronously through the sliding plate 321, thereby improving the moving stability and smoothness of the heat conducting block 22.

[0063] In the embodiment of the present invention, as Figures 4 to 8 shown, the pushing block 31 is wedge-shaped. Guide walls 221 for sliding cooperation with the pushing block 31 are formed at positions corresponding to the pushing block 31 on the two heat conducting blocks 22. Among them, the guide wall 221 for sliding cooperation with the upper side of the pushing block 31 is inclined downward from top to bottom in the left-right direction, and the guide wall 221 for sliding cooperation with the lower side of the pushing block 31 is inclined upward from bottom to top in the left-right direction. The wedge-shaped pushing block 31 can be in contact with the guide wall 221 and stably support the heat conducting block 22 when sliding to any position along the guide wall 221, further improving the moving stability of the heat conducting block 22. Moreover, by pushing the two heat conducting blocks 22 with the wedge-shaped pushing block 31, it is ensured that the insertion gap 23 between the two heat conducting blocks 22 can be stably increased, effectively preventing the reaction tube 200 from wearing the heating sheet 21.

[0064] In the embodiment of the utility model, the housing 10 includes a cover 14, a mounting plate 15 and a panel 16, the temperature control component 20 is installed in the cover 14, the cover 14 is provided with a mounting opening 141 at a position corresponding to the heat conducting block 22, the mounting plate 15 is provided at the mounting opening 141, and the mounting ear 12 is provided on the side of the mounting plate 15 facing the inside of the cover 14, the slide groove 13 and the socket 11 are both provided on the mounting plate 15, and the mounting plate 15 is also provided with a guide groove 151, the sliding plate 321 is provided with a guide rod 324, the guide rod 324 can be slidably penetrated in the guide groove 151, the guide groove 151 extends in the left and right directions, and the sliding plate 3 When the push block 31 is driven by the guide wall 221 to slide, the sliding plate 321 can also synchronously drive the guide rod 324 to slide along the guide groove 151. The sliding cooperation between the guide rod 324 and the guide groove 151 plays a role of guiding the sliding, further improving the sliding smoothness. The guide rod 324 can adopt fasteners such as bolts or screws in the prior art. The guide rod 324 passes through the mounting plate 15 and the sliding plate 321 in sequence, and the head of the guide rod 324 abuts against the mounting plate 15, which plays a role of connecting the mounting plate 15 and the sliding plate 321 and limiting the mounting plate 15, effectively preventing the mounting plate 15 from being loosened from the sliding plate 321. In addition, the panel 16 is arranged on the side of the mounting plate 15 away from the cover 14, and the panel 16 plays a role of protecting the mounting plate 15 and decorating the appearance.

[0065] In the embodiment of the utility model, the temperature control component 20 further includes a heat sink 24 and a heat pipe 25. The heat sink 24 is disposed in the housing 10 and spaced apart from the heat conducting block 22. The two ends of the heat conducting pipe 25 are respectively embedded in the heat conducting block 22 and the heat sink 24 in a one-to-one correspondence. Figures 2 to 8 As shown, the heating plate 21 is arranged on the side of the heat conductive block 22 facing the insertion gap 23. After the heating plate 21 completes heating the reaction tube 200, the heat can be conducted to the heat conductive pipe 25 through the heat conductive block 22, and then to the heat sink 24 through the heat conductive pipe 25 to achieve rapid cooling. The heat sink 24 and the heat conductive block 22 are arranged at intervals in the shell 10, which not only saves space, but also allows the heat to dissipate quickly during the conduction process, thereby improving the cooling rate.

[0066] Furthermore, the heat sink 24 includes a plurality of heat sink fins 241 arranged at intervals, and the heat pipes 25 pass through the plurality of heat sink fins 241 respectively. The heat pipes 25 have high heat transfer efficiency, and the plurality of heat sink fins 241 increase the heat dissipation area, greatly improving the cooling rate. In addition, a plurality of heat dissipation holes 142 arranged at intervals are provided on the housing 14 at positions corresponding to the plurality of heat sink fins 241, and the heat on the heat sink fins 241 can be dissipated to the outside of the housing 14 through the heat dissipation holes 142, thereby ensuring the stability and reliability of cooling.

[0067] In an embodiment of the present utility model, the temperature control component 20 further includes a cooling fan 26, and the cooling fan 26 is disposed on one side of the heat dissipation base 24 and is located between the heat conduction block 22 and the heat dissipation base 24. As Figures 2 to 8 shown, the cooling fan 26 is disposed inside the housing 14, and the cooling fan 26 is used to blow air toward the heat dissipation base 24, so that the heat on the heat dissipation fins 241 can quickly escape from the heat dissipation holes 142 to the outside of the housing 14, further accelerating the cooling rate. Moreover, the heat conduction block 22 and the heat dissipation base 24 are respectively disposed on both sides of the cooling fan 26, and the heat conduction tube 25 extends from the heat conduction block 22 toward the heat dissipation base 24 and bypasses the cooling fan 26. The installation position of the cooling fan 26 increases the length of the heat conduction tube 25, thereby increasing the distance between the heating sheet 21 and the heat dissipation base 24, enabling the heat to gradually dissipate during the conduction process and improving the cooling effect.

[0068] In an embodiment of the present utility model, a heat conduction layer is coated on the side of the heating sheet 21 facing the heat conduction block 22, and the heat conduction layer is sandwiched between the heating sheet 21 and the heat conduction block 22 to quickly conduct the heat generated by the heating sheet 21 to the heat conduction block 22, further improving the cooling rate.
