Each example is provided for the purpose of explaining this application and not for limiting it. In fact, those skilled in the art will understand that various modifications and variations can be made to this application without departing from the scope or spirit of this application. For example, a feature illustrated or described as part of one embodiment may be used with another embodiment to produce yet another embodiment. As used in this specification, the terms “first,” “second,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of the components. As used in this specification, unless the context clearly indicates otherwise, the terms “a,” “an,” “the,” and “the” are intended to indicate the presence of one or more elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be other elements in addition to those listed.

[0042] Referring now to the accompanying drawings, in which the same numbers denote the same elements throughout the drawings, the present disclosure will be further explained below in conjunction with specific embodiments.

[0043] Figure 1 This is one of the structural schematic diagrams of a precision temperature control device provided in an embodiment of this disclosure. Figure 1 As shown, the precision temperature control device provided in this embodiment may include a housing 1, a reaction device 3, and a sealing cap 4. The housing 1 may be a cuboid structure, and the reaction device 3 may be disposed above the housing 1 to contain reactants and react with them. The reaction device 3 may be located on the upper surface of the housing 1, or partially or completely embedded within the housing 1. The sealing cap 4 may be disposed above the upper surface of the housing 1 to ensure that the reaction device 3 remains in a sealed space during operation.

[0044] Optionally, the sealing cover 4 has two working states: open and closed. Figure 1 The operating state shown is with the sealing cover 4 open. With the sealing cover 4 open, the user can operate the reactants or reaction equipment in the reaction apparatus 3.

[0045] Figure 2 This is a second schematic diagram of a precision temperature control device provided in an embodiment of this disclosure. Figure 2 As shown, when the sealing cover 4 is in the closed state, the sealing cover 4 covers the entire reaction device 3 to ensure that the reactants in the reaction device 3 can react fully in the sealed space and avoid interference from the external environment.

[0046] Optionally, the precision temperature control device in this embodiment may further include a heat dissipation device 5, which is disposed inside the housing 1 for controlling the temperature of the reaction device 3. To further improve heat dissipation efficiency, heat dissipation holes may also be provided on the housing 1 at a position opposite to the location of the heat dissipation device 5.

[0047] Furthermore, the precision temperature control device of this embodiment may also include a drive device 2, which is located inside the housing 1 and is used to control the working state of the sealing cover 4. That is, the sealing cover 4 can be opened or closed by the drive device 2 without manual control of the sealing cover 4, thus improving work efficiency and user experience.

[0048] Figure 3 This is one of the internal structural diagrams of a precision temperature control device provided in an embodiment of this disclosure. Figure 3 As shown, the sealing cover 4 in this embodiment of the present disclosure also includes a driven device. The driving device 2 can control the working state of the sealing cover 4 by controlling the driven device through the synchronous belt 7. That is, the driving device 2 can drive the driven device through the synchronous belt 7 to open or close the sealing cover 4.

[0049] Optionally, the driven device in the sealing cover 4 can consist of a driven wheel 41 and a rotating shaft passing through the central axis of the driven wheel 41. There can be one or more driven wheels 41. The rotating shaft is fixed to one side inside the sealing cover 4. When the driven wheel 41 is driven by the driving device 2, the driven wheel 41 drives the rotating shaft to rotate. Further, the rotating shaft drives one side of the sealing cover 4 to rotate, thereby opening or closing the sealing cover 4. Specifically, the driving device 2 includes a stepper motor 21 and a drive wheel 22. The drive wheel 22 is connected to the driven wheel 41 in the driven device of the sealing cover 4 via a synchronous belt 7. During operation, the stepper motor 21 drives the drive wheel 22 to rotate. The rotation of the drive wheel 22 drives the driven wheel 41 to rotate via the synchronous belt 7, and consequently, the fixed rotating shaft also rotates with the driven wheel 41.

[0050] In one possible implementation, the sealing cover 4 includes a cover shell, a spring 43, and a heated cover 42. The heated cover 42 and spring 43 are disposed inside the sealing cover 4. One end of the spring 43 can be connected to the cover shell, and the other end to the heated cover 42. Optionally, the spring 43 can be fixed to the cover shell or the heated cover 42 by passing through it or by fixing it to one side of the cover shell or the heated cover 42. Further, when the sealing cover 4 is closed, the heated cover 42 is tightly fitted to the reaction device 3, with the upper surface of the cover directly above the reaction device 3. To further enhance the sealing effect and ensure a sealed reaction environment for the reaction device 3, a sealing ring or sealing gasket or other sealing structure can be provided around the heated cover 42. Optionally, the heated cover 42 can also include a heating film and a temperature sensor. The heating film is used to further heat the reaction environment of the reaction device 3, and the temperature sensor is used for precise temperature control to prevent condensation from accumulating on the upper surface of the heated cover 42, which could affect the reaction process.

[0051] Furthermore, the sealing cover 4 can also have a quick-release function, allowing the heating cover 42 to be quickly removed while the sealing cover 4 is in the open state, facilitating the replacement of components such as the heating cover 42, heating film, and sealing gasket, and making it easier to clean the heating cover 42. This quick-release function can further improve the overall user experience of the sealing cover 4 and the precision temperature control device.

[0052] Figure 4 This is a second schematic diagram of the internal structure of a precision temperature control device provided in an embodiment of this disclosure. Figure 4 As shown, the heat dissipation device 5 in the precision temperature control device of this embodiment includes a Peltier 51 and a heat dissipation device. The Peltier 51 is positioned above the heat dissipation device 5 and directly below the reaction device 3. For example, the Peltier 51 can be directly embedded in the upper surface of the housing 1, or fixed inside the housing 1 by a bracket or other means and positioned directly below the reaction device 3. The heat dissipation device 5 is located inside the housing 1, below the Peltier 51. Optionally, the heat dissipation device 5 may include at least one heat dissipation component 52, such as a fan 522 or a radiator 521. The Peltier 51 can be positioned with the cold side facing upwards and the hot side facing downwards. When the reaction device 3 heats the reactants, the Peltier 51 and the heat dissipation device 5 are not activated to increase the temperature inside the reaction device 3. When the reaction device 3 cools the reactants, the Peltier 51 and the heat dissipation device 5 are activated, and the cold surface of the Peltier 51 cools the reaction device 3.

[0053] Optionally, the reaction apparatus 3 may include a reaction tank 31 and a cover plate 32. The reaction tank 31 is disposed above the outer casing 1 and has an upward-facing groove for containing the reaction medium. The cover plate 32 covers the groove of the reaction tank 31 and has multiple sets of parallel-arranged placement holes. Each set of placement holes includes a predetermined number of placement holes arranged in sequence at equal intervals. These placement holes are used to insert a reaction tube 6 containing reactants. The reaction medium can be any heat-conducting medium such as water or oil, used to cool the placed reactants through heat conduction via the Peltier 51, or to heat the placed reactants through heat conduction via the heating film. Alternatively, the reaction medium may also include at least two chemicals that generate heat after reaction, to cool the placed reactants.

[0054] Furthermore, temperature sensors can be installed on both sides of the reaction tank 31 to monitor the temperature in real time during the reaction process, thereby achieving precise temperature control and preventing experimental failure due to temperature changes. Optionally, the precision temperature control device in this embodiment may also include a control device connected to the temperature sensors, used to receive temperature information sent by the sealing cover 4 and / or the temperature sensors installed on both sides of the reaction tank 31, and to control the heat dissipation device 5 to adjust the temperature or control the drive device 2 to open the sealing cover 4 when the temperature fluctuates unexpectedly.

[0055] Figure 5 This is one of the structural schematic diagrams of a reaction apparatus provided in an embodiment of this disclosure. For example... Figure 5 As shown, the reaction device 3 also includes at least one set of latches 33. At least one vertical mounting groove group extending through multiple sets of storage holes is provided above the cover plate 32. Each mounting groove group includes multiple mounting slots arranged at intervals in sequence, and each mounting slot is located on at least one side of a set of storage holes. That is, each mounting slot is located on both sides of the intersection of the storage hole group and the mounting groove group, and the mounting groove group may have one mounting slot on each side of each intersection with a storage hole. Optionally, each set of latches 33 is fixedly installed in multiple mounting slots within a mounting groove group, with one latch 33 installed in one mounting slot, and the number of latches 33 matches the number of mounting slots in the mounting groove group.

[0056] Furthermore, each set of placement holes is used to hold a set of reaction tubes 6 comprising a predetermined number of reaction tubes 6, and every two reaction tubes 6 in the set of reaction tubes 6 are connected by a connector 8. Optionally, the reaction tubes 6 in the set of reaction tubes 6 can be PCR reaction tubes 6.

[0057] Figure 6 This is a second schematic diagram of a reaction apparatus provided in an embodiment of this disclosure. Figure 6As shown, the buckle 33 is a U-shaped structure consisting of a bottom and two sides perpendicular to the bottom. The sides of the buckle 33 are parallel to the storage hole group, that is, the two sides of the U-shaped structure are parallel to the storage hole group. A guide and fixing member 331 with a protrusion on the opposite side is provided on the outer side of the buckle 33. Optionally, the bottom of the buckle 33 is provided with a fixing hole for fixed connection with the cover plate 32.

[0058] Furthermore, the guide fixing component 331 includes an upper surface and a lower surface, and the upper surface, the lower surface, and a portion of the side of the latch 33 form a protruding structure with a triangular side. When the reaction tube 6 group is located within the storage hole group, the intersection of the upper and lower surfaces is located above the connector 8. That is, the upper surface of the guide fixing component 331 and the side of the latch 33 form an upper chamfer 3311, which serves as a guide when the user places the reaction tube 6 group into the storage hole group. The upper surface of the guide fixing component 331 and the side of the latch 33 form a lower chamfer 3312, which prevents the reaction tube 6 group from being lifted when the sealing cover 4 is opened by restricting the upward movement of the connector 8.

[0059] Based on the above technical features, this embodiment provides a compact and precise temperature control device structure. The overall working efficiency of the precise temperature control device is improved by using a drive device 2 to open and close the sealing cover 4. A latch 33 is provided above the cover plate 32 to prevent the reaction tube 6 from being lifted when the sealing cover 4 is opened. Furthermore, this embodiment uses a heat dissipation device 5 and a temperature sensor to precisely control the reaction environment temperature of the reaction tube 6. The drive device 2 further controls the automatic opening of the sealing cover 4 when the ambient temperature is problematic, preventing accidents.
