Detailed Description of the Invention

[0022] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0023] To better understand the above technical solution, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be fully conveyed to those skilled in the art.

[0024] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0025] The following reference Figures 1-4 will be used to describe in detail the implementation of the heating and oscillation unit proposed according to the embodiments of the present utility model.

[0026] The heating and oscillation unit according to the embodiments of the present utility model includes: a carrier assembly 1 and an oscillation driving member 2.

[0027] Specifically, the carrier assembly 1 has a heating element 11, a carrier plate 12 and an elastic heat conducting member 13. The heating element 11 is connected to the carrier plate 12 to heat the carrier plate 12. The carrier plate 12 defines a first positioning hole 121 for placing a test tube 4. The elastic heat conducting member 13 is disposed at the opening of the first positioning hole 121. The first positioning hole 121 and the elastic heat conducting member 13 jointly abut against and position the test tube 4, and transfer heat to the test tube 4. The oscillation driving member 2 is connected to the carrier assembly 1 to drive the carrier assembly 1 to oscillate.

[0028] That is to say, the heating element 11 is suitable for heating the carrier plate 12, and the first positioning hole 121 of the carrier plate 12 is suitable for placing test tubes 4 of different specifications, and the test tubes 4 are filled with test liquid. When the heating element 11 heats the carrier plate 12, the overall temperature of the carrier plate 12 rises and transfers heat to the test tube 4 placed in the first positioning hole 121. Since the contact surface sizes of different test tubes 4 and the first positioning hole 121 are different, the heat transferred from the first positioning hole 121 to the test tube 4 is limited, so that the test tube 4 receives heat slowly. The elastic heat conductive member 13 abuts against the test tube 4 in the first positioning hole 121, so that test tubes 4 of different specifications can be positioned, and at the same time, the test tube 4 can synchronously receive the heat transferred by the first positioning hole 121 and the elastic heat conductive member 13, thereby increasing the heating speed of the test liquid in the test tube 4, and then cooperates with the oscillation driving member 2 to make the test liquid in the test tube 4 oscillate while being heated, thereby accelerating the reaction of the test liquid.

[0029] Thus, the carrier plate 12 is heated by the heating element 11 of the carrier assembly 1, so that the heat of the carrier plate 12 is transferred to the test liquid in the test tube 4 in the first positioning hole 121 through the first positioning hole 121 and the elastic heat conductive element 13. The heating oscillation unit can be suitable for test tubes 4 of different specifications and can ensure the reliability of heating the test liquid in the test tube 4.

[0030] For the installation of the heating element 11, the carrier plate 12 defines a mounting hole 122, and the heating element 11 is inserted into the mounting hole 122. It can be understood that by inserting the heating element 11 into the mounting hole 122 of the carrier plate 12, the installation of the heating element 11 is easier and convenient for subsequent replacement. The heating element 11 can be a heating rod, the mounting hole 122 can be set on one side of the carrier plate 12, and the heating element 11 can pass through the gap between each column of the first positioning holes 121, so as to improve the uniformity of heating of the carrier plate 12.

[0031] For the elastic heat conductive member 13, the elastic heat conductive member 13 is constructed with a second positioning hole 14 that can be elastically deformed, and the test tube 4 can be placed into the first positioning hole 121 from the second positioning hole 14, so that the first positioning hole 121 and the second positioning hole 14 abut and position the test tube 4. It can be understood that, through the setting of the second positioning hole 14, it is convenient for test tubes 4 of different specifications to be placed into the first positioning hole 121 from the second positioning hole 14, and to be abutted and positioned by the first positioning hole 121 and the second positioning hole 14, so as to avoid the test tube 4 from tipping over and causing the test liquid to leak out, and at the same time, it is convenient for the first positioning hole 121 and the second positioning hole 14 to transfer heat to the test liquid in the test tube 4. Among them, the shape of the second positioning hole 14 can be set according to the shape of the test tube 4, so that the second positioning hole 14 is in full contact with the test tube 4 to improve the heat transfer efficiency.

[0032] For the elastic heat conducting member 13, the second positioning hole 14 is triangular. Understandably, the triangular second positioning hole 14 formed by the elastic heat conducting member 13 facilitates the triangular positioning of the outer peripheral arm of the test tube 4, not only ensuring the reliability of the positioning of the test tube 4, but also facilitating the insertion and removal of the test tube 4. Among them, the triangular second positioning hole 14 can be formed by three elastic heat conducting members 13 connected end to end and installed on the carrier plate 12. A single elastic heat conducting member 13 can be cylindrical, which is convenient for reducing the resistance to the insertion and removal of the test tube 4.

[0033] For the oscillation driving member 2, the oscillation driving member 2 has an eccentric rotating shaft 21, a first mounting plate 22 and a second mounting plate 23. The carrier assembly 1 is movably connected to the first mounting plate 22 in the X-axis direction, and the first mounting plate 22 is movably connected to the second mounting plate 23 in the Y-axis direction. The eccentric rotating shaft 21 is connected to the carrier assembly 1 to drive the carrier assembly 1 to move synchronously in the X-axis direction and the Y-axis direction for oscillation. Understandably, by movably connecting the carrier assembly 1 to the first mounting plate 22 in the X-axis direction and movably connecting the first mounting plate 22 to the second mounting plate 23 in the Y-axis direction, the eccentric rotating shaft 21 can drive the carrier plate 12 to perform an eccentric motion, thereby realizing the oscillation of the test solution in the test tube 4, which is beneficial to the full mixing of the test solution and accelerating the reaction. Among them, the movement of the carrier assembly 1 in the X-axis direction between the carrier assembly 1 and the first mounting plate 22 can be realized by the cooperation of a slide rail and a slider, and the movement of the first mounting plate 22 in the Y-axis direction between the second mounting plate 23 and the first mounting plate 22 can also be realized by the cooperation of a slide rail and a slider, so as to realize the movement of the carrier plate 12 in the X-axis direction and the Y-axis direction.

[0034] For the carrier assembly 1, the carrier assembly 1 includes a heat insulation plate 15 and a third mounting plate 16. The carrier plate 12 is connected to the heat insulation plate 15, the heat insulation plate 15 is connected to the third mounting plate 16, the third mounting plate 16 is connected to the eccentric rotating shaft 21, and the third mounting plate 16 is movably connected to the first mounting plate 22 in the X-axis direction. Understandably, through the setting of the third mounting plate 16, it is convenient for the connection between the carrier assembly 1 and the oscillation driving member 2. Through the setting of the heat insulation plate 15, the heat on the carrier plate 12 can be prevented from being transferred to the third mounting plate 16, thereby preventing the oscillation driving member 2 from being damaged due to excessive temperature. Among them, the rotation of the eccentric rotating shaft 21 can be realized by a motor cooperating with a belt and a pulley.

[0035] For the adjustment of the oscillation intensity, it further includes an oscillation controller 3. The oscillation controller 3 is adapted to be connected to the oscillation driving member 2 to adjust the oscillation intensity of the oscillation driving member 2 on the carrier assembly 1. Understandably, through the setting of the oscillation controller 3, it is convenient to adjust the oscillation intensity of the test solution in the test tube 4, so that the test solution reacts more fully, and at the same time, it can also prevent the test solution from leaking out of the test tube 4.

[0036] In addition, a temperature control sensor can also be provided on the carrier plate 12 to facilitate monitoring the heating temperature of the test solution in the test tube 4 at any time.
