[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Figure 1 and Figure 2 The schematic diagram of the structure of the heating device provided by the utility model from different perspectives, wherein the heating device is used to heat the reagent box. Figure 1 and Figure 2 As shown, the heating device comprises:

[0038] A heating seat 1, wherein the heating seat 1 is used to set a heating component 2 for providing heat;

[0039] The heat-conducting block 3 is arranged on the heating seat 1. The heating seat 1 can receive the heat provided by the heating component 2. The heat-conducting block 3 is provided with a heat-conducting groove 31 for contacting with the reagent box 4 for heating.

[0040] In the above heating device, the heating component can heat the heat-conducting block, and the heat can be transferred to the reagent kit through the heat-conducting groove on the heat-conducting block, so that the reagent kit is heated, thereby promoting the reaction of the reagents in the reagent kit. As a result, the heat-conducting groove can increase the contact area with the reagent kit, thereby improving the heating efficiency of the reagent kit, and can quickly heat the reagent kit to a temperature that meets the reaction temperature of the reagents therein, thereby improving the reaction efficiency.

[0041] In one embodiment, the heat-conducting groove 31 is used to heat the bottom of the reagent box. Preferably, the shape of the heat-conducting groove is adapted to the bottom of the reagent box to be heated.

[0042] When the shape of the heat conductive groove matches the bottom of the reagent kit, heat can be better transferred to the reagent kit through the heat conductive groove, thereby improving the efficiency of heating the reagent kit.

[0043] Figure 3 , Figure 4 and Fig. 9 The structural diagram of the test kit is shown in FIG. 4 , in which the bottom of the test kit 4 includes a first arcuate portion 41 which is arc-shaped and recessed from the inside to the outside of the test kit, a second arcuate portion 42 which is respectively connected to both sides of the first arcuate portion 41, and a third arcuate portion 43 which is connected to the two second arcuate portions 42. The connecting line formed by the highest point and the lowest point of the first arcuate portion, the second arcuate portion and the third arcuate portion is a smoothly transitioned curve.

[0044] The bottom structure of the test kit can effectively increase the heating area when the bottom is heated, thereby improving the heating efficiency of the test kit.

[0045] Correspondingly, since the heat-conducting groove needs to be in contact with the bottom of the reagent box, the structure of the heat-conducting groove needs to fit the structure of the bottom of the reagent box.

[0046] like Figure 5 As shown, it shows that the bottom of the reagent box fits tightly with the thermal conductive groove.

[0047] like Figure 6 As shown, it shows the specific structure of the heat-conducting groove 31, and the heat-conducting groove 31 includes a first arc-shaped heat conductor 51 for correspondingly fitting the first arc-shaped portion 41, two second arc-shaped heat conductors 52 arranged on both sides of the first arc-shaped heat conductor 51 for correspondingly fitting the second arc-shaped portion 42, and two third arc-shaped heat conductors 53 respectively connected to the two second arc-shaped portions 52 for correspondingly fitting the third arc-shaped portion 43.

[0048] like Figure 7 As shown, it shows a cross-sectional view of the bottom structure of the test kit, which more clearly shows the structural diagram of the bottom of the test kit.

[0049] from Figure 6 and Figure 7 It can be seen that by designing the bottom of the reagent box and the heat-conducting groove into the above-mentioned arc-shaped structure, the heat-conducting groove 31 can be closely fitted with the bottom of the reagent box 4, and there will be no gap after fitting. In this way, under this structure, the contact area between the heat-conducting groove and the bottom of the reagent box is greatly increased. When the reagent box is heated, the heat of the heat-conducting groove 31 can be transferred to the bottom of the reagent box more, thereby improving the heating efficiency of the reagent box and improving the reaction rate of the reagent inside the reagent box.

[0050] The connecting line formed by the highest point and the lowest point of the first arc portion, the second arc portion and the third arc portion is a gently transitioning curve. Figure 7 The shape of the curve is shown more clearly, as Figure 7 As shown, the profile curve is a smoothly transitioned curve, which enables the reagents therein to flow more smoothly into the bottom of the reagent box, so that the reagents inside are fully mixed, thereby accelerating the reaction between the internal liquids and improving the reaction efficiency.

[0051] In one embodiment, the heating component 2 is in direct contact with the heat-conducting block 3 for heat conduction. Preferably, the heating component 2 is a heating rod, and / or the heating seat 1 is made of non-metal or metal material.

[0052] It can be understood that when the heating seat 1 is made of non-metallic material, the heating component 2 can directly contact the heat-conducting block 3 for heating. When the heating seat 1 is made of metal material, the heating seat 1 has a heat-conducting effect, and the heating component 2 can heat the heating seat 1 and then the heating seat 1 transfers the temperature to the heat-conducting block 3.

[0053] In one embodiment, the heating seat 1 comprises:

[0054] The hollow portion is arranged inside the heating seat 1 along the distribution direction of the heat-conducting grooves 31 , and the hollow portion is used to arrange the heating component 2 . Preferably, the heating component 2 is a heating rod, and / or the heating seat is made of metal material.

[0055] The heating component 2 is arranged along the direction of the heat conducting groove 31, and the length of the heatable component is increased, and the heating component can increase the heating area, so that more heat is transferred to the outside to achieve rapid heating. When the heating component 2 is arranged inside the heating seat through the hollow part, the heat generated by the heating component 2 can heat the heating seat more quickly, thereby heating the reagent kit through the heating seat, thereby achieving the purpose of rapidly heating the reagent kit.

[0056] In one embodiment, the heating device is mounted on a base 6 of the extraction device for placing the reagent kit. Preferably, the heating seat 1 matches with a mounting groove on the base 6 to fix the heating device.

[0057] The heating device provided in this embodiment is applied to an extraction device, and the extraction device can be an extraction instrument (such as a nucleic acid extraction instrument) or other physical device that can use the above heating device. Specific extraction devices are not listed one by one in this embodiment.

[0058] like Figure 8 As shown, the heating device is installed on the base 6 in the extraction equipment. Correspondingly, a mounting groove for mounting the heating device is provided on the base 6, and the heating seat 1 can be installed in the mounting groove to fix the heating device.

[0059] In one embodiment, Figure 1 As shown, the heat conductive block 3 is further provided with a vertical fixing notch 32 at at least one position matching with the fixing strip 44 of the reagent kit 4, and the fixing notch 32 is used to accommodate the fixing strip 44 to fix the reagent kit when the heating device is matched and installed with the reagent kit.

[0060] like Figure 1 and Figure 4 As shown, there are at least two corresponding fixing slots on the heat conductive block. By the fixed cooperation between the fixing strip 44 and the fixing slot 32, when the reagent kit 4 is matched and installed with the heating device, the reagent kit can be effectively fixed on the heating device to avoid instability of the reagent kit during the heating process or the moving process, resulting in leakage of the reagent in the reagent kit.

[0061] In one embodiment, the heating device is formed in one piece, that is, the heating seat and the heating block are an integrally formed structure. Preferably, the material of the heating device contains metal material, more preferably, contains copper material.

[0062] Copper material has good thermal conductivity, and the heating device contains copper material, which can better heat.

[0063] This embodiment also provides a kit, such as Figure 3 and Figure 4 As shown, the reagent kit 4 is provided with at least one fixing strip 44, and the fixing strip 44 is used to match and install with the fixing slot 32 on the heating device when the reagent kit is placed on the heating device to fix the reagent kit. Preferably, the reagent kit is adapted to the above-mentioned heating device.

[0064] In this embodiment, when the reagent kit is matched with the heating device, the reagent kit can be firmly fixed on the heating device by matching the fixing bar with the fixing slot so that it will not shake; the reagent kit can be matched with the above-mentioned heating device, so that the heating device can quickly heat the reagent kit through the heat conduction groove, so that the reagent kit can be quickly heated to a temperature that meets the reaction temperature of the reagents therein, thereby improving the reaction efficiency.

[0065] This embodiment also provides an extraction device, which includes the heating device mentioned above, and the heating device is used to match and place a corresponding reagent kit.

[0066] The heating device is an independent module structure and can be installed and disassembled in the extraction equipment.

[0067] In this embodiment, after the reagent kit is placed in the extraction device, the reagent kit can be quickly heated by a heating device, thereby improving the heating efficiency of the reagent kit, enabling the reagent kit to be quickly heated to a temperature that meets the reaction temperature of the reagents therein, thereby improving the reaction efficiency.

[0068] like Figure 8 As shown, the extraction device also includes a base 6, on which is provided a mounting groove (not shown) corresponding to the heating seat. When the heating seat 1 is embedded in the mounting groove, the heat conductive block 3 is fixed to the upper surface of the base 6.

[0069] like Figure 8 As shown, since the heating seat 1 is entirely embedded in the mounting groove, and the heat conducting block 3 is fixed to the upper surface of the base 6, when the heating device is installed on the base 6, it is only necessary to insert the heating device into the mounting groove, which facilitates the installation of the heating device. When the heating device is removed from the mounting groove, it is only necessary to pull the heating device out of the mounting groove, which facilitates the disassembly of the heating device.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
