Example one

In the molecular detection technology, the sample storage bin 100 in the kit 127 needs to be subjected to a heating treatment, such as proteinase K treatment, and the temperature is usually 55-60 ℃; in this embodiment, a heating device is provided for heating a sample storage bin 100, as shown in fig. 4 and 5, the bottom of the sample storage bin 100 is provided with heating cavities 101 arranged at intervals, wherein the heating cavity 101 has a trapezoidal longitudinal section, and specifically, the heating cavity 101 extending inward from the bottom wall of the sample storage bin 100 has a tapered structure.

In this embodiment, as shown in fig. 1 and 2, the heating device includes a heating assembly 102 and a heat conductive sleeve 103; a heat conduction sleeve 103 is sleeved at the heating end part of the heating component 102; wherein, the heat conducting sleeve 103 is matched with the heating cavity 101; specifically, in order to satisfy the heating cavity 101 with a trapezoidal longitudinal section, the heat conducting sleeve 103 is preferably of a hexahedral structure, and one end surface of the heat conducting sleeve is an inclined surface which can be matched with the inclined surface in the heating cavity 101; more specifically, in view of the small space of the heating chamber 101, in order to improve the heating efficiency of the heating element 102, an end surface of the heat conductive sleeve 103 is provided as an inclined surface having a large contact area with the inclined surface of the accommodating chamber adapted thereto, thereby improving the heating efficiency of the heating element 102 to the sample storage chamber 100.

It should be noted that, for the heating chamber 101 with a trapezoidal longitudinal section, an explanation is given of the hexahedral structure of the heat conducting sleeve 103; if the structure of the heating cavity 101 is other polyhedral structures, the structure of the heat-conducting sleeve 103 can be changed, as long as the heat-conducting sleeve can be attached to the inner wall of the heating cavity 101.

In the actual heating process, as shown in fig. 4 and 5, first, the heating assembly 102 heats the heat-conducting sleeve 103 to a set temperature; then, the heating end of the heating assembly 102 is inserted into the heating cavity 101 in cooperation with the heat conduction sleeve 103, so that the heat conduction sleeve 103 is tightly attached to the end surface of the heating cavity 101, and the heating efficiency of the heating assembly 102 is improved; the heating device solves the technical problems that the heating sheet 104 in the prior art can not be in close contact with the heating cavity 101, so that the heating time is long and the heating efficiency is low.

In this embodiment, in order to ensure a close fit between the heat-conducting sleeve 103 and the heating cavity 101, thereby improving the heating efficiency of the heating assembly 102, the heat-conducting sleeve 103 is formed by a silica gel material; specifically, the heat conducting sleeve 103 made of the silicone material has the characteristics of expansion with heat and contraction with cold, and when the heat conducting sleeve 103 is heated, the heated heat conducting sleeve 103 expands, so that the heat conducting sleeve and the heating cavity 101 are tightly attached to each other, and the heating efficiency of the heating assembly 102 is improved.

In this embodiment, as shown in fig. 3, in order to further ensure a close fit between the heat-conducting sleeve 103 and the heating cavity 101, thereby improving the heating efficiency of the heating assembly 102, the heating assembly 102 includes a heating plate 104 and a temperature sensor 105 welded to the heating plate 104 by using a patch thermistor; the heat conducting sleeve 103 is sleeved on the heating sheet 104, and the heating sheet 104 comprises a substrate 106 and a heating wire 107; the heating wire 107 is disposed on the substrate 106.

On one hand, because the heat conducting sleeve 103 made of the silica gel material has the characteristics of expansion with heat and contraction with cold, when the heat conducting sleeve 103 is heated, the heated heat conducting sleeve 103 expands; on the other hand, since the heating plate 104 made of stainless steel material has a certain toughness, that is, in the heating process, the cooperation between the heating plate 104 and the heat conducting sleeve 103 generates a small amount of outward deformation, and this deformation can make the heat conducting sleeve 103 and the heating cavity 101 tightly fit with each other, thereby improving the heating efficiency of the heating assembly 102.

In addition, considering that the heating cavity 101 has a small volume, the heating sheet 104 is made as thin as possible, and therefore, the substrate 106 is made of stainless steel material, the heating wire 107 is a thick film heating wire, and the thick film heating wire is printed on the substrate 106; by adopting the printing technology, on one hand, the thickness of the heating sheet 104 is thin, on the other hand, the heating of the heating wire 107 is not influenced, and the heat conduction effect is better.
