[0027] Detailed Implementation

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] The POCT device and its temperature control system according to the present invention are described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, in this embodiment, a temperature control system is proposed. The temperature control system includes a heat dissipation module, an adjustment module, and a temperature control module. The heat dissipation module includes two heat dissipation parts spaced apart along the height direction. The adjustment module is sandwiched between the two heat dissipation parts and includes two mounting plates spaced apart along the height direction and an adjustment component. The temperature control module is connected to an external transmission optical fiber 100. The temperature control module includes two temperature control units 8 respectively mounted on the opposite surfaces of the two mounting plates. The adjustment component is used to adjust the relative distance between the two mounting plates to move the two temperature control units 8 closer to or further apart.

[0031] The temperature control system in this embodiment incorporates an adjustment component, allowing for adjustment of the relative distance between the two mounting plates, and consequently, the distance between the two temperature control units 8. Both temperature control units 8 can be independently activated for temperature control to meet the needs of different operating conditions, ensuring the system achieves rapid heating and precise temperature control, thus solving the technical problem of poor temperature control accuracy in existing technologies. The temperature control unit 8 utilizes a Peltier sensor, enabling rapid heating and precise temperature control, thereby improving the overall detection rate of the POCT equipment.

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the two mounting plates are a first mounting plate 21 and a second mounting plate 22. The adjustment assembly includes a sliding plate 23. The second mounting plate 22 is located between the first mounting plate 21 and the sliding plate 23. A groove 221 is provided on the second mounting plate 22. A protrusion 9 is provided on the opposite side of both the first mounting plate 21 and the sliding plate 23. The wedge-shaped surfaces of the two protrusions 9 engage and are both placed within the groove 221. The groove 221 serves as a guide and limiter, ensuring that the protrusions 9 on the first mounting plate 21 and the sliding plate 23 can slide along the length of the groove 221. The wedge-shaped surfaces of the protrusions 9 on the first mounting plate 21 and the wedge-shaped surfaces of the protrusions 9 on the sliding plate 23 are opposite and parallel to each other, ensuring smooth engagement of the two protrusions 9. The groove 221 extends in the left-right direction, and its width matches the width of the protrusions 9.

[0033] When it is necessary to adjust the distance between the two temperature control units 8, the slide plate 23 is driven to slide to the right, so that the protrusion 9 on the slide plate 23 abuts against the protrusion 9 on the first mounting plate 21. Under the action of the wedge-shaped surface, the first mounting plate 21 moves upward and away from the second mounting plate 22, thereby increasing the distance between the two temperature control units 8. If it is necessary to decrease the distance between the two temperature control units 8, the slide plate 23 can be manually driven to slide to the left. At this time, the protrusion 9 on the slide plate 23 and the protrusion 9 on the first mounting plate 21 will separate from each other, and the first mounting plate 21 moves downward and closer to the second mounting plate 22, thereby decreasing the distance between the two temperature control units 8. In addition, both temperature control units 8 can be turned on independently for temperature control to meet the needs of different working conditions. The sliding plate 23 can be driven to slide by the operator manually or by a linear drive component, such as a hydraulic cylinder, to drive the slide plate 23 to slide back and forth.

[0034] Furthermore, in this embodiment, there are two sliding grooves 221 symmetrically arranged on the second mounting plate 22. Similarly, four protrusions 9 are also provided on the first mounting plate 21 and the sliding plate 23 respectively to ensure the stability of distance adjustment between the first mounting plate 21 and the second mounting plate 22. The number of protrusions 9 and sliding grooves 221 can be adjusted according to actual needs.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the heat dissipation module also includes heat dissipation fins 12, and the heat dissipation part includes heat dissipation plate 11. The heat dissipation plate 11 and the heat dissipation fins 12 are connected by multiple heat pipes 13. The two heat dissipation plates 11 are respectively arranged on the side opposite to each other of the first mounting plate 21 and the slide plate 23, absorbing the heat emitted by the temperature control unit 8 from the upper and lower directions, thereby improving the overall heat dissipation rate of the device.

[0036] Specifically, the two heat sinks 11 are symmetrically arranged along their height to ensure that the heat transferred from the two temperature control units 8 to the heat sinks 11 is consistent and the heat dissipation is uniform. Each heat sink 11 includes two plate sections spaced apart along its length. Four heat dissipation fins 12 are provided, each corresponding to one of the plate sections. Three heat pipes 13 are connected between each plate section and each heat dissipation fin 12. One end of each heat pipe 13 is inserted into the plate section, and the other end is inserted into the heat dissipation fin 12, efficiently transferring heat from the heat sink 11 to the heat dissipation fin 12, thus improving the overall heat dissipation efficiency of the temperature control system. The number of heat pipes 13 can be adjusted according to actual needs. In this embodiment, the multiple heat pipes 13 are evenly distributed, ensuring that the overall temperature of the temperature control system tends to be balanced.

[0037] It should be noted that the length direction is... Figure 1 The left and right directions and the height direction are respectively. Figure 1 The vertical direction and the width direction are respectively. Figure 1 The front and back directions in the middle.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the temperature control system also includes a heat dissipation bracket 3, and the heat dissipation module also includes a heat dissipation fan 14 mounted on the heat dissipation bracket 3. The heat dissipation fins 12 and the heat dissipation fan 14 are located on both sides of the heat dissipation bracket 3, and the heat dissipation fins 12 are disposed on the side of the heat dissipation bracket 3 facing the temperature control unit 8.

[0039] In this embodiment, two cooling fans 14 are provided, which, together with the heat dissipation fins 12, can better dissipate the heat from the heat dissipation fins 12 to the external space, achieving a better heat dissipation effect and reducing the temperature at the temperature control unit 8. The number of cooling fans 14 can be adjusted according to actual needs. Furthermore, the temperature control system also includes a support frame 6, which is located below the heat dissipation plate 11, supporting the heat dissipation plate 11 and preventing the components above from directly contacting the ground, thus avoiding contamination of the temperature control system by ground debris. A pad 7 is also installed at the bottom of the heat dissipation bracket 3 and the support frame 6, further improving the overall stability of the temperature control system.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown in this embodiment, both the first mounting plate 21 and the second mounting plate 22 have storage slots 10 for accommodating the temperature control unit 8. The sliding plate 23 has an opening 4 corresponding to the temperature control unit 8 to allow for its movement and facilitate heat transfer from the temperature control unit 8 to the heat sink 11, effectively reducing the temperature of both temperature control units 8. The length direction of the sliding plate 23 corresponds to the left-right direction in the figure. The storage slots 10 on the first mounting plate 21 and the second mounting plate 22 are rhomboid in shape and corresponding to the shape of the temperature control unit 8, facilitating its accommodation. The opening 4 on the sliding plate 23 is elongated and extends along the length direction of the sliding plate 23.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the second mounting plate 22 is also provided with a mounting hole 222. The temperature control system also includes a locking module 5 provided on the heat sink 11 located above. The locking module 5 includes a locking rod 51 and an elastic element 52. The top end of the locking rod 51 is provided with a limiting ring 53. The elastic element 52 is sleeved on the outer peripheral wall of the locking rod 51 and elastically connected between the limiting ring 53 and the heat sink 11. The locking rod 51 passes through the heat sink 11 located above, the first mounting plate 21, and the second mounting plate 22 in sequence and is inserted into the mounting hole 222.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, there are multiple locking modules 5, which are distributed around the perimeter of the upper heat sink 11. Specifically, this embodiment provides four locking modules 5, which can stably press the first mounting plate 21 and the second mounting plate 22 together, preventing relative wobbling between the first mounting plate 21 and the second mounting plate 22 during the adjustment process, thus avoiding affecting the adjustment effect. The number of locking modules 5 can be adjusted according to actual needs.

[0043] In this embodiment, the surfaces of both temperature control units 8 are covered with a thermally conductive layer. Specifically, the thermally conductive layer is made of thermally conductive silicone with a high thermal conductivity, which satisfies the positioning and adhesion of the Peltier to the mounting plate, while the high thermal conductivity of the silicone satisfies the heat transfer requirements.

[0044] like Figure 5 As shown, in this embodiment, the adjustment component includes a grip handle 24 disposed on the side end face of the skateboard 23, which is convenient for the staff to hold. The staff can easily slide and adjust the skateboard 23 by pulling the grip handle 24, reducing the difficulty of adjusting the skateboard 23.

[0045] In this embodiment, a POCT (point-of-care testing) device is also proposed. This is a point-of-care testing device that performs tests on-site using portable analytical instruments and accompanying reagents to quickly obtain results. It includes the temperature control system described above. Since the POCT device employs all embodiments of the temperature control system, it also possesses all the beneficial effects brought by the temperature control system, which will not be elaborated upon here.
