[0030] This application proposes a heating device, see Figures 1 to 5 , Figure 1 is a schematic diagram of the axial structure of the first embodiment of the heating device of the present application, Figure 2 This is one of the axial structural schematic diagrams of the second embodiment of the heating device of the present application. Figure 3 is one of the cross-sectional structural schematic diagrams of the second embodiment of the heating device of the present application, Figure 4 This is the second axial structural diagram of the second embodiment of the heating device of the present application. Figure 5 FIG. 2 is a schematic cross-sectional view of the second embodiment of the heating device of the present application. Figures 1 to 5 As shown, the heating device includes a heating component 101 , a first heat-conducting member 102 and a heat-conducting component 103 .

[0031] The heating component 101 can be specifically used to heat the object connected to its heating end. For example, the heating end of the heating component 101 can refer to the heating element 1011, and the heating element 1011 can be connected to the first heat conducting element 102 for heating.

[0032] Among them, Figure 1As shown, the heating component 101 may specifically include a heating element 1011, a temperature sensor 1012 and a temperature control switch 1013. The temperature control switch 1013 may be connected to the heating element 1011 and the temperature sensor 1012, respectively. The temperature control switch 1013 may be used to control the heating element 1011 to stop heating when the temperature sensor 1012 detects that the temperature of the heating element 1011 or the object heated by the heating element 1011 exceeds a preset temperature threshold, and / or control the heating element 1011 to heat when the temperature sensor 1012 detects that the temperature of the heating element 1011 or the object heated by the heating element 1011 does not exceed the preset temperature threshold.

[0033] The first heat-conducting member 102 includes a tube groove 1021 , and the tube groove 1021 is used to place the sample tube 201 . The heating component 101 is used to heat the first heat-conducting member 102 .

[0034] Among them, Figure 1 , Figure 2 and Figure 4 As shown, the first heat-conducting member 102 may have a tube groove 1021. After the sample tube 201 is placed in the tube groove 1021, the heating member 1011 connected to the first heat-conducting member 102 in the heating assembly 101 is controlled to heat the first heat-conducting member 102, thereby indirectly heating the tube groove 1021 and the sample tube 201 therein through heat conduction.

[0035] The heat conducting component 103 is disposed in the tube groove 1021 and is located between the first heat conducting member 102 and the sample tube 201 , so that the heat conducting component 103 and the sample tube 201 are closely attached to each other.

[0036] Among them, the heat-conducting component 103 can specifically be a flexible component, which can be fitted with the inserted sample tube 201 when the sample tube 201 is placed in the tube groove 1021, and the heat-conducting component 103 can also conduct the heat on the first heat-conducting component 102 through the larger contact area between it and the sample tube 201, thereby realizing efficient heating of the sample in the sample tube 201.

[0037] Specifically, Figures 2 to 5 As shown, the heating device may also include a thermal insulation component 104, which may be arranged on the side wall outside the first heat-conducting component 102 to insulate the first heat-conducting component 102. The thermal insulation component 104 may specifically be thermal insulation cotton, or may be a component formed by other types of materials with thermal insulation or heat-insulating properties, which is not limited here.

[0038] In one example, the heat conductive component 103 may be disposed around the side wall of the sample tube 201 to achieve a surrounding fit arrangement for the sample tube 201 .

[0039] Different from the prior art, in the technical solution of the present application, the heating component can be used to heat the first heat-conducting member, and the first heat-conducting member is provided with a tube groove, which can be used to place the sample tube. A heat-conducting component is also provided in the tube groove, and the heat-conducting component is located between the first heat-conducting member and the sample tube, and is used to be fitted with the sample tube. Based on the above method, when the heating component heats the first heat-conducting member, the first heat-conducting member can conduct heat to the heat-conducting component, and then conduct heat to the sample tube through the fitting arrangement of the heat-conducting component and the sample tube, thereby achieving heating of the sample through the fitted heat-conducting component, thereby increasing the contact area between the heating device and the sample tube, and thereby improving the heating efficiency of the heating device for the sample tube.

[0040] In one embodiment, the heat conducting assembly 103 includes a second heat conducting member 1031 .

[0041] The first heat conducting member 102 includes a groove 1022 disposed on a side wall of the tube slot 1021 , and the second heat conducting member 1031 is disposed in the groove 1022 .

[0042] Specifically, Figure 3 and Figure 5 As shown, a groove 1022 may be provided on the side wall of the tube groove 1021 , and the second heat conducting member 1031 may be provided in the groove body space of the groove 1022 .

[0043] The second heat-conducting member 1031 may specifically be a flexible member with heat-conducting capability, such as heat-conducting rubber, heat-conducting silica gel, and other types of heat-conducting members with flexible material structures and certain heat-conducting efficiency, which are not limited here.

[0044] Based on the above method, when the sample tube 201 is built into the tube groove 1021, the second heat-conducting member 1031 is arranged in the groove 1022, so that the flexible member with heat-conducting ability is located between the sample tube 201 and the first heat-conducting member 102, and the second heat-conducting member 1031 can be deformed and fitted onto the sample tube 201. Compared with heating the sample tube 201 only through the tube groove 1021 of the first heat-conducting member 102, the contact area between the heating device and the sample tube 201 can be increased through the fitting arrangement, thereby improving the heat conduction efficiency and improving the heating efficiency of the sample tube 201 by the heating device.

[0045] Optionally, the thermal conductive component 103 further includes a ventilation component 1032 .

[0046] The ventilation component 1032 is connected to the groove 1022, and the ventilation component 1032 is used to inflate the gap between the groove 1022 and the second heat conductor 1031 when the heating component 101 is heating, and / or is used to connect the gap between the groove 1022 and the second heat conductor 1031 with the outside world when the heating component 101 stops heating.

[0047] Specifically, Figure 4 and Figure 5 As shown, when the heating component 101 is heating, the gap between the groove 1022 and the second heat-conducting member 1031 can be inflated through the ventilation component 1032 to apply pressure to the side of the second heat-conducting member 1031 away from the sample tube 201, thereby increasing the contact area between the second heat-conducting member 1031 and the sample tube 201, thereby further improving the heating efficiency of the heating device for the sample tube 201.

[0048] After the heating component 101 completes heating of the sample tube 201, the gap between the groove 1022 and the second heat-conducting component 1031 can be connected to the outside atmosphere through the ventilation component 1032 to balance the air pressure and reduce the pressure applied by the second heat-conducting component 1031 to the sample tube 201, so as to facilitate the user to remove the heated sample tube 201 from the heating device and improve convenience.

[0049] In one embodiment, when the groove 1022 described above is provided on the side wall of the tube groove 1021, the ratio value obtained by dividing the axial length of the groove 1022 in the tube groove 1021 by the axial length of the tube groove 1021 in the tube groove 1021 is not less than 1 / 6 and not greater than 1.

[0050] Specifically, Figure 5 As shown, the length of the groove 1022 in the axial direction of the tube groove 1021 may be referred to as a length S1 , and the length of the tube groove 1021 in the axial direction of the tube groove 1021 may be referred to as a length S2 .

[0051] The value obtained by dividing the length S1 by the length S2 is not less than 1 / 6 and not greater than 1, that is, the axial length of the groove 1022 in the tube groove 1021 is not greater than the axial length of the tube groove 1021 in the tube groove 1021, and the axial length of the groove 1022 in the tube groove 1021 is not less than 1 / 6 of the axial length of the tube groove 1021 in the tube groove 1021.

[0052] Based on the above method, it can ensure that the fitting length of the heat conductive component 103 to the sample tube in the axial direction of the tube groove 1021 is large enough, thereby ensuring that the heating efficiency of the heating device to the sample tube 201 is high enough, thereby improving the reliability of the heating device.

[0053] In one embodiment, at least two support members (not shown) are further disposed on the side wall of the tube groove 1021 . The at least two support members are disposed around the side wall of the sample tube 201 at intervals, and the support members are used to abut against the sample tube 201 .

[0054] Specifically, the support member can be used to provide support force to the sample tube 201 in a direction perpendicular to the axial direction of the tube groove 1021, so as to reduce the possibility that the sample tube 201 tilts in the tube groove 1021, resulting in the failure of the thermal conductive component 103 to effectively fit or other unexpected situations, thereby improving the reliability of the heating device.

[0055] In one embodiment, the heating device further comprises a pressurizing assembly (not shown).

[0056] The pressurizing component is used to pressurize the heat conducting component 103 in the axial direction of the tube groove 1021 , so that the heat conducting component 103 is deformed and expanded in a direction perpendicular to the axial direction of the tube groove 1021 , and fits the sample tube 201 .

[0057] Specifically, the boost component can be a component used to apply axial pressure to the tube groove 1021 of the heat conductive component 103. The specific way of providing pressure can be to provide axial contact pressure, to provide axial air pressure, or other ways of providing pressure, which are not limited here.

[0058] Based on the above method, the axial force of the tube groove 1021 exerted on the heat conductive component 103 can be increased, thereby causing the heat conductive component 103 to deform and expand in a direction perpendicular to the axial direction of the tube groove 1021, so as to better fit the sample tube 201, further increase the contact area and improve the heating efficiency.

[0059] The present application also proposes a heating device, see Figure 1 , Figure 6 and Figure 7 , Figure 1 is a schematic diagram of the axial structure of the first embodiment of the heating device of the present application, Figure 6 is a schematic diagram of the axial structure of the third embodiment of the heating device of the present application, Figure 7 : is a schematic cross-sectional view of the third embodiment of the heating device of the present application. Figure 1 , Figure 6 and Figure 7 As shown, the heating device includes a heating component 101 , a first heat-conducting member 102 and a heat-conducting component 103 .

[0060] The heating component 101 can be specifically used to heat the object connected to its heating end. For example, the heating end of the heating component 101 can refer to the heating element 1011, and the heating element 1011 can be connected to the first heat conducting element 102 for heating.

[0061] Among them, Figure 1As shown, the heating component 101 may specifically include a heating element 1011, a temperature sensor 1012 and a temperature control switch 1013. The temperature control switch 1013 may be connected to the heating element 1011 and the temperature sensor 1012, respectively. The temperature control switch 1013 may be used to control the heating element 1011 to stop heating when the temperature sensor 1012 detects that the temperature of the heating element 1011 or the object heated by the heating element 1011 exceeds a preset temperature threshold, and / or control the heating element 1011 to heat when the temperature sensor 1012 detects that the temperature of the heating element 1011 or the object heated by the heating element 1011 does not exceed the preset temperature threshold.

[0062] The first heat-conducting member 102 includes a tube groove 1021 , and the tube groove 1021 is used to place the sample tube 201 . The heating component 101 is used to heat the first heat-conducting member 102 .

[0063] Among them, Figure 1 and Figure 6 As shown, the first heat-conducting member 102 may have a tube groove 1021. After the sample tube 201 is placed in the tube groove 1021, the heating member 1011 connected to the first heat-conducting member 102 in the heating assembly 101 is controlled to heat the first heat-conducting member 102, thereby indirectly heating the tube groove 1021 and the sample tube 201 therein through heat conduction.

[0064] The heat conducting component 103 is disposed in the tube groove 1021 and is located between the first heat conducting member 102 and the sample tube 201 , so that the heat conducting component 103 and the sample tube 201 are closely attached to each other.

[0065] Among them, the heat-conducting component 103 can specifically be a flexible component, which can be fitted with the inserted sample tube 201 when the sample tube 201 is placed in the tube groove 1021, and the heat-conducting component 103 can also conduct the heat on the first heat-conducting component 102 through the larger contact area between it and the sample tube 201, thereby realizing efficient heating of the sample in the sample tube 201.

[0066] Specifically, Figure 6 and Figure 7 As shown, the heating device may also include a thermal insulation component 104, which may be arranged on the side wall outside the first heat-conducting component 102 to insulate the first heat-conducting component 102. The thermal insulation component 104 may specifically be thermal insulation cotton, or may be a component formed by other types of materials with thermal insulation or heat-insulating properties, which is not limited here.

[0067] In one example, the heat conductive component 103 may be disposed around the side wall of the sample tube 201 to achieve a surrounding fit arrangement for the sample tube 201 .

[0068] Different from the prior art, in the technical solution of the present application, the heating component can be used to heat the first heat-conducting member, and the first heat-conducting member is provided with a tube groove, which can be used to place the sample tube. A heat-conducting component is also provided in the tube groove, and the heat-conducting component is located between the first heat-conducting member and the sample tube, and is used to be fitted with the sample tube. Based on the above method, when the heating component heats the first heat-conducting member, the first heat-conducting member can conduct heat to the heat-conducting component, and then conduct heat to the sample tube through the fitting arrangement of the heat-conducting component and the sample tube, thereby achieving heating of the sample through the fitted heat-conducting component, thereby increasing the contact area between the heating device and the sample tube, and thereby improving the heating efficiency of the heating device for the sample tube.

[0069] In one embodiment, the heat conducting assembly 103 includes a second heat conducting member 1033 and a heat conducting fluid 1034 .

[0070] The second heat conducting member 1033 is disposed on the side wall of the tube groove 1021 . The first heat conducting member 102 includes a groove 1022 disposed on the side wall of the tube groove 1021 . An accommodating cavity is formed between the first heat conducting member 102 and the second heat conducting member 1033 at the groove 1022 .

[0071] The heat transfer fluid 1034 is disposed in the accommodating cavity.

[0072] Specifically, Figure 7 As shown, a groove 1022 may be provided on the side wall of the tube groove 1021, and the second heat conductive member 1033 may be arranged in a fit with the portion of the side wall of the tube groove 1021 where the groove 1022 is not provided, thereby forming a receiving cavity with the first heat conductive member 102 in the groove body space of the groove 1022, and the heat conducting fluid 1034 is located in the receiving cavity.

[0073] The second heat-conducting member 1033 can specifically be a thermally conductive film, for example, tin foil or other types of thermally conductive films, which are used to separate the thermally conductive fluid 1034 and the sample tube 201, and can be used to transfer the heat from the first heat-conducting member 102 to the thermally conductive fluid 1034, and further transfer it to the sample tube 201.

[0074] Based on the above method, when the sample tube 201 is built into the tube groove 1021, the second heat conductive member 1033 and the heat conductive fluid 1034 are arranged in the groove 1022, and the second heat conductive member 1033 can be deformed and fitted onto the sample tube 201. Compared with heating the sample tube 201 only through the tube groove 1021 of the first heat conductive member 102, the contact area between the heating device and the sample tube 201 can be increased through the fitting arrangement, thereby improving the heat conduction efficiency and improving the heating efficiency of the sample tube 201 by the heating device.

[0075] Optionally, the thermal conductive component 103 further includes a ventilation component 1032 .

[0076] The ventilation component 1032 is connected to the groove 1022, and is used to inflate the gap between the groove 1022 and the second heat conductor 1033 when the heating component 101 is heating, and / or to connect the gap between the groove 1022 and the second heat conductor 1033 with the outside world when the heating component 101 stops heating.

[0077] The height of the ventilation component 1032 is greater than the height of the liquid level of the heat transfer fluid 1034 .

[0078] Specifically, specifically, such as Figure 7 As shown, when the heating component 101 is heating, the gap between the groove 1022 and the second heat-conducting member 1033 can be inflated through the ventilation component 1032 to apply pressure to the side of the second heat-conducting member 1033 facing away from the sample tube 201, thereby increasing the contact area between the second heat-conducting member 1033 and the sample tube 201, and further improving the heating efficiency of the heating device for the sample tube 201.

[0079] After the heating component 101 completes heating of the sample tube 201, the gap between the groove 1022 and the second heat-conducting component 1033 can be connected to the outside atmosphere through the ventilation component 1032 to balance the air pressure and reduce the pressure applied by the second heat-conducting component 1033 to the sample tube 201, so as to facilitate the user to remove the heated sample tube 201 from the heating device and improve convenience.

[0080] Alternatively, if Figure 7 As shown, the heating device may further include a pressing plate 105 .

[0081] The pressing plate 105 can be fixedly connected to the first heat-conducting member 102 , and the second heat-conducting member 1033 can be sandwiched between the pressing plate 105 and the first heat-conducting member 102 to achieve fixation.

[0082] Based on the above method, the relative stability between the second heat conductive member 1033 and the first heat conductive member 102 can be effectively improved, the possibility of sample contamination or sample damage caused by leakage of the heat conductive fluid 1034 due to misalignment between the second heat conductive member 1033 and the first heat conductive member 102 can be reduced, and the reliability of the heating device can be improved.

[0083] Alternatively, if Figure 7 As shown, the heating device may further include a support 106 and a screw 107 .

[0084] The seat 106 and the nut of the screw 107 can both be located at the bottom of the tube groove 1021, and the seat 106 and the nut of the screw 107 are located in the second heat conductive member 1033, the screw rod of the screw 107 passes through the seat 106 and the second heat conductive member 1033 and is threadedly connected to the first heat conductive member 102, and the nut of the screw 107 abuts against the top of the seat 106 to clamp the second heat conductive member 1033 between the seat 106 and the first heat conductive member 102 to achieve fixation.

[0085] Based on the above method, the relative stability between the second heat conductive member 1033 and the first heat conductive member 102 can be effectively improved, the possibility of sample contamination or sample damage caused by leakage of the heat conductive fluid 1034 due to misalignment between the second heat conductive member 1033 and the first heat conductive member 102 can be reduced, and the reliability of the heating device can be improved.

[0086] In one embodiment, when the groove 1022 described above is provided on the side wall of the tube groove 1021, the ratio value obtained by dividing the axial length of the groove 1022 in the tube groove 1021 by the axial length of the tube groove 1021 in the tube groove 1021 is not less than 1 / 6 and not greater than 1.

[0087] Specifically, Figure 7 As shown, the length of the groove 1022 in the axial direction of the tube groove 1021 may be referred to as a length S1 , and the length of the tube groove 1021 in the axial direction of the tube groove 1021 may be referred to as a length S2 .

[0088] The value obtained by dividing the length S1 by the length S2 is not less than 1 / 6 and not greater than 1, that is, the axial length of the groove 1022 in the tube groove 1021 is not greater than the axial length of the tube groove 1021 in the tube groove 1021, and the axial length of the groove 1022 in the tube groove 1021 is not less than 1 / 6 of the axial length of the tube groove 1021 in the tube groove 1021.

[0089] Based on the above method, it can ensure that the fitting length of the heat conductive component 103 to the sample tube in the axial direction of the tube groove 1021 is large enough, thereby ensuring that the heating efficiency of the heating device to the sample tube 201 is high enough, thereby improving the reliability of the heating device.

[0090] In one embodiment, at least two support members (not shown) are further disposed on the side wall of the tube groove 1021 . The at least two support members are disposed around the side wall of the sample tube 201 at intervals, and the support members are used to abut against the sample tube 201 .

[0091] Specifically, the support member can be used to provide support force to the sample tube 201 in a direction perpendicular to the axial direction of the tube groove 1021, so as to reduce the possibility that the sample tube 201 tilts in the tube groove 1021, resulting in the failure of the thermal conductive component 103 to effectively fit or other unexpected situations, thereby improving the reliability of the heating device.

[0092] In one embodiment, the heating device further comprises a pressurizing assembly (not shown).

[0093] The pressurizing component is used to pressurize the heat conducting component 103 in the axial direction of the tube groove 1021 , so that the heat conducting component 103 is deformed and expanded in a direction perpendicular to the axial direction of the tube groove 1021 , and fits the sample tube 201 .

[0094] Specifically, the boost component can be a component used to apply axial pressure to the tube groove 1021 of the heat conductive component 103. The specific way of providing pressure can be to provide axial contact pressure, to provide axial air pressure, or other ways of providing pressure, which are not limited here.

[0095] Based on the above method, the axial force of the tube groove 1021 exerted on the heat conductive component 103 can be increased, thereby causing the heat conductive component 103 to deform and expand in a direction perpendicular to the axial direction of the tube groove 1021, so as to better fit the sample tube 201, further increase the contact area and improve the heating efficiency.

[0096] This application also proposes a sample analyzer, see Figure 8 , Figure 8 is a schematic diagram of the structure of an embodiment of the sample analyzer of the present application, such as Figure 8 As shown, the sample analyzer 30 includes a heating device 31 and a mixing device 32 .

[0097] The heating device 31 is used to heat the sample in the sample tube 201 .

[0098] The mixing device 32 is used to mix the sample in the sample tube 201 .

[0099] Different from the prior art, in the technical solution of the present application, the heating component can be used to heat the first heat-conducting member, and the first heat-conducting member is provided with a tube groove, which can be used to place the sample tube. A heat-conducting component is also provided in the tube groove, and the heat-conducting component is located between the first heat-conducting member and the sample tube, and is used to be fitted with the sample tube. Based on the above method, when the heating component heats the first heat-conducting member, the first heat-conducting member can conduct heat to the heat-conducting component, and then conduct heat to the sample tube through the fitting arrangement of the heat-conducting component and the sample tube, thereby achieving heating of the sample through the fitted heat-conducting component, thereby increasing the contact area between the heating device and the sample tube, and thereby improving the heating efficiency of the heating device for the sample tube.

[0100] The present application also proposes a control method for a sample analyzer, which is applied to Figure 8 The sample analyzer shown may further include a detection device 33 .

[0101] See also Fig. 9 , Fig. 9 FIG. 1 is a flow chart of an embodiment of a control method of a sample analyzer of the present application. Fig. 9 As shown, the control method includes:

[0102] Step S11 : firstly controlling the heating device to heat the sample in the sample tube 201 , and then controlling the mixing device to mix the sample in the sample tube 201 .

[0103] Step S12: Control the detection device to detect the sample in the sample tube 201 to obtain the detection result.

[0104] Specifically, in practice, if the sample in the sample tube 201 is mixed first and then heated, the sample that should have been mixed may easily precipitate during the heating due to the long heating time, thereby rendering the mixing effect ineffective, and easily distorting the subsequent test results based on the sample.

[0105] Based on the above-mentioned method of first controlling the heating device to heat the sample in the sample tube 201, and then controlling the mixing device to mix the sample in the sample tube 201, the above-mentioned problem can be avoided, so that the heated sample can still maintain a certain temperature within a shorter mixing time, while ensuring the effectiveness of heating and mixing, thereby improving the accuracy of subsequent sample testing.

[0106] Different from the prior art, in the technical solution of the present application, the heating component can be used to heat the first heat-conducting member, and the first heat-conducting member is provided with a tube groove, which can be used to place the sample tube. A heat-conducting component is also provided in the tube groove, and the heat-conducting component is located between the first heat-conducting member and the sample tube, and is used to be fitted with the sample tube. Based on the above method, when the heating component heats the first heat-conducting member, the first heat-conducting member can conduct heat to the heat-conducting component, and then conduct heat to the sample tube through the fitting arrangement of the heat-conducting component and the sample tube, thereby achieving heating of the sample through the fitted heat-conducting component, thereby increasing the contact area between the heating device and the sample tube, and thereby improving the heating efficiency of the heating device for the sample tube.
