In addition, the technical features involved in each of the embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0053] In the utility model, the words "up", "down" and "horizontal" are used to facilitate the understanding of the structure of the mixing device by the person skilled in the art, and are not used to limit the state of the mixing device after being installed in the use scene.

[0054] The embodiment provides a mixing device and a reagent mixing system. Figures 1 to 10 As shown in the figure, the mixing device comprises a support 1, a rotating shaft 2, a rotating bin module 3 and a fastening mechanism 5. The reagent mixing system comprises the mixing device and a reagent box 4. The rotating shaft 2 is rotatably arranged on the support 1 about the axis line of the rotating shaft 2, the rotating shaft 2 has an eccentric section, the rotating bin module 3 is arranged on the eccentric section 20, the rotating bin module 3 comprises a plurality of rotating bins 31, the fastening mechanism 5 is arranged on the side wall of the rotating bin 31, the rotating bin 31 and the reagent box 4 are relatively fixed through the fastening mechanism 5 and can be quickly disassembled.

[0055] As shown in the figure, Figure 3 The reagent mixing system is connected and fixed with each component through the support 1, the support 1 is provided with a power supply and a motor, the power supply serves as the power source for the rotation of the motor, the motor (a rotary motor, which can further be a reciprocating motor) drives the rotating shaft to rotate, and drives the rotating bin module 3 and the plurality of reagent boxes 4 to rotate.

[0056] As shown in the figure, Figure 7 The rotating shaft 2 is horizontally arranged and has one or more eccentric sections. In the embodiment, the eccentric section comprises a first eccentric section 21 and a second eccentric section 22. The center lines of the first eccentric section 21 and the second eccentric section 22 do not coincide, the center line of the eccentric section 20 deviates from the axis line of the rotating shaft 2, the distance (also referred to as eccentric distance) between the center line of the eccentric section 20 and the axis line of the rotating shaft 2 is 1-5mm, and in the embodiment, the eccentric distance is 2mm. The size of the eccentric distance determines the amplitude of the vibration of the rotating bin 31. The rotating shaft 2 can also be increased in length as required, a plurality of eccentric sections 20 can be additionally provided, and a plurality of rotating bin modules 3 and reagent boxes 4 can be installed.

[0057] As shown in the figure, Figures 3 to 6 The plurality of rotating bins 31 arranged around the eccentric section 20 are arranged in the circumferential direction of the eccentric section 20, and the rotating bin module 3 formed by the plurality of rotating bins 31 is arranged on the rotating shaft 2. In the embodiment, every four rotating bins 31 form a rotating bin module 3, the first rotating bin module 3 is installed on the first eccentric section 21, and the second rotating bin module 3 is installed on the second eccentric section 22. This arrangement allows the capacity of the mixing device to be flexibly configured according to the number of reagent boxes 4 to be processed or the scale of the reaction. If a large number of reagents need to be processed, the number of eccentric sections 20 can be flexibly expanded, so that a corresponding number of rotating bin modules 3 can be arranged thereon. The rotating bin module 3 is designed to be standardized, which further improves the flexibility of expansion.

[0058] Further, as shown in the figure,Figure 8 As shown, the rotating bin 31 has an open end 310 on the side of the rotating bin 31 further away from the eccentric section 20. The rotating bin 31 also has a cavity for accommodating the reagent box 4. Referring to Figure 3 As shown, the reagent box 4 is configured to hold reagents to be mixed, and a plurality of reagent tubes 8 holding the reagents to be mixed are placed in the reagent box 4. In this embodiment, the plurality of reagent tubes 8 are placed along the length direction of the rotating shaft 2. That is, the reagent tubes 8 are horizontally arranged. This design increases the capacity of the mixing device, and a larger amount of reagent boxes 4 can be loaded at one time. The reagents in a plurality of reagent boxes 4 can be mixed synchronously, improving the efficiency.

[0059] Referring to Figure 8 As shown, the fastening mechanism 5 is arranged on at least two opposite side walls of the rotating bin 31, which can further effectively clamp the reagent box 4 and fix it relative to the rotating bin 31. After the mixing is completed, the reagent box 4 can be quickly and conveniently separated from the rotating bin 31. The fastening mechanism 5 includes a plurality of fastening units 51, which are arranged at intervals along the diameter direction or the circumferential direction of the eccentric section 20. The fastening unit 51 includes a pressing member 510, which includes a pressing portion arranged on the rotating bin 31 and movable, and the pressing portion has a retracted position and an extended position protruding inwardly into the cavity. The fastening unit 51 also includes a resilient member arranged between the pressing portion and the surface (e.g., the inner surface) of the rotating bin 31, which can be a compression spring, for example. By arranging the elastic fastening mechanism 5, the reagent box 4 can be conveniently put in or taken out, and at the same time, it can be ensured that the reagent box 4 will not be separated from the rotating bin 31 during the rotation and oscillation.

[0060] Referring to Figure 9 As shown, one or more side surfaces of the reagent box 4 are provided with a plurality of positioning grooves 41 extending upward from the bottom edge of the side surface. The positioning grooves 41 cooperate with the fastening units 51 of the side walls of the rotating bin 31, and the pressing portion of the fastening unit 51 can be inserted into the positioning groove 41 to fix the rotating bin 31 and the reagent box 4, and the reagent box 4 can also be quickly separated from the rotating bin 31.

[0061] It should be further noted that the length of the positioning groove 41 is less than the height of the reagent box 4, and the above-mentioned fastening mechanism 5 is offset from the bottom of the rotating bin 31 by a distance. The reagent box 4 is inserted into the rotating bin 31 in a side-lying manner. In the first stage of insertion of the reagent box 4, the pressing member 510 is extruded, and the resilient member is in a deformed state to allow the wider part of the reagent box 4 to enter the rotating bin 31. When the pressing member 510 enters the positioning groove 41, the resilient member resets, and the pressing portion of the pressing member 510 is in its extended position, clamping the reagent box 4. The insertion is convenient and fast, and the elasticity of the resilient member allows the reagent box 4 to be quickly taken out.

[0062] Figure 10 Another rotating chamber according to an embodiment of the present invention is shown. (Refer to...) Figure 10 As shown, multiple stepped surfaces 311 are formed on the bottom of the two side walls of the rotating chamber 31 that are not equipped with fastening mechanisms 5. Each stepped surface 311 faces the inner cavity of the rotating chamber 31, and multiple slots of different widths are formed between each stepped surface 311 and the opposing stepped surface 311 or the inner surface of the rotating chamber 31, thereby accommodating reagent kits 4 of different sizes. After the reagent kit 4 is inserted, a portion of the reagent kit 4 is locked in the slot of the corresponding width and held in place by the fastening mechanisms 5 on both sides. Furthermore, multiple stepped surfaces can also be formed on the bottom of the two side walls of the rotating chamber 31 that are equipped with fastening mechanisms 5, and the stepped surfaces on the four side walls cooperate with each other to accommodate reagent kits 4 of different sizes.

[0063] Reference Figures 1 to 3 As shown, the mixing device also includes a timer 6 and a speed controller 7. The timer 6 is used to adjust the rotation time of the rotating shaft 2, and the speed controller 7 is used to adjust the rotation speed of the rotating shaft 2, thereby adjusting the vibration effect. The higher the rotation speed, the more obvious the vibration. The speed controller 7 is configured to control the rotation speed of the rotating shaft 2 to 20-150 rpm. By controlling the rotation time and the rotation speed, the mixing rate of the reagent to be mixed can be adjusted.

[0064] The rotating shaft 2 has an eccentric section 20. The center line of the eccentric section 20 is offset from the axis of the rotating shaft 2. The eccentric section 20 can rotate when the motor drives the rotating shaft 2, so that the reagent kit 4 rotates periodically on the rotating shaft 2, accompanied by the periodic vibration of the reagent tube 8 containing the reagent to be mixed inside the reagent kit 4. There will be a vibration with an amplitude of 1~5mm (e.g. 2mm) for each rotation. This achieves that the reagent to be mixed is not only rotated and mixed, but also vibrated and mixed as a whole, improving the mixing effect of the reagent to be mixed and promoting the full fusion of the reagents.

[0065] The working principle of the above mixing device is as follows:

[0066] The reagent tube 8 containing the reagents to be mixed is placed into the reagent kit 4. The reagent kit 4 is then placed into the rotating chamber 31 of the rotating chamber module 3. The positioning groove 41 of the reagent kit 4 and the fastening mechanism 5 on the side wall of the rotating chamber 31 cooperate to fix the reagent kit 4. The power supply 8 is turned on, and the motor is started. The motor drives the rotating shaft 2 to rotate. The center line of the eccentric section 20 deviates from the axis of the rotating shaft 2. During the rotation of the rotating chamber module 3 formed by the eccentric section 20, the reagent tube 8 inside the reagent kit 4 vibrates periodically. This achieves the mixing of the reagents to be mixed by rotation and vibration, thereby improving the mixing effect of the reagents to be mixed.

[0067] Further, or in another embodiment, the mixing device can also control vibration to cause the rotating shaft 2 to reciprocate at a high frequency at a certain angle. The reagents in the reagent kit 4 can be mixed due to inertia. Under the action of the rotary motor, the rotating shaft 2 moves to a position such as 45° or 135°, and the circular motion stops. Under the action of the reciprocating motor, the rotating shaft 2 reciprocates at a high frequency of ±2° at that angle, promoting thorough mixing of the reagents. Specifically, the mixing device includes a controller electrically connected to the motor to control the start / stop and rotation direction of the motor. The mixing device further includes a sensor electrically connected to the controller to detect whether the rotating shaft has moved to a set position, such as the aforementioned 45° or 135° position.

[0068] The above-mentioned mixing device has at least the following advantages:

[0069] In this embodiment, the mixing device has an eccentric section 20 on the rotating shaft 2. The center line of the eccentric section 20 deviates from the axis of the rotating shaft 2, causing the reagent kit 4 to rotate periodically on the rotating shaft 2, accompanied by periodic vibration of the reagent tube 8 containing the reagent to be mixed inside the reagent kit 4. This achieves simultaneous rotational mixing and overall vibration mixing of the reagent to be mixed, improving the mixing effect of the reagent to be mixed. The rotating chamber 31 has a modular design. Compared with an integrated design, the installation and disassembly process of the rotating chamber 31 and the reagent kit 4 is simpler, improving the loading and unloading efficiency of the rotating chamber 31 and the reagent kit 4. The structure is simple and the equipment is stable.

[0070] This embodiment provides another mixing device, which is consistent with... Figures 1 to 7 The mixing devices shown are basically the same, with the difference being that the rotating shaft 2 does not have an eccentric section 20, and the rotating chamber module 3 is directly fixed to the rotating shaft 2. Furthermore, multiple rotating chamber modules 3 can be arranged along the axial direction of the rotating shaft 2. Each rotating chamber module 3 includes multiple rotating chambers 31, which are spaced apart around the circumference of the rotating shaft 2. Driven by a reciprocating motor, the rotating shaft 2 reciprocates within a set angle range (e.g., ±2°) to achieve reagent mixing.
