[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, an embodiment of the utility model provides a stirring device, which includes a support seat 100, a mounting assembly 200 and a stirring assembly 300. Among them, the mounting assembly 200 is arranged on the support seat 100, and the mounting assembly 200 is used to fix the container containing the material, and the mounting assembly 200 can drive the container to rotate, and the container is tilted in the vertical direction. The stirring assembly 300 is movably arranged on the support seat 100, and the stirring assembly 300 can be relatively close to or away from the mounting assembly 200. The stirring assembly 300 includes a rotating motor 310 and a stirring rod 320, and the rotating motor 310 is drivingly connected to the stirring rod 320, and is used to drive the stirring rod 320 to rotate, and the output shaft of the rotating motor 310 is coaxially arranged with the container, and the rotation direction of the stirring rod is opposite to the rotation direction of the container.

[0029] By applying the technical solution of the present invention, the stirring device includes a support seat 100, an installation component 200 and a stirring component 300. After the container for containing the material is installed on the installation component 200, the installation component 200 can drive the container to rotate and the container has a certain inclination angle relative to the vertical direction. In this way, during the mixing process of the materials, even if the content of some materials is small, during the rotation of the container with the installation component 200, the materials will move in the container along the extension direction of the container under the combined action of gravity and the stirring rod 320, which is beneficial to the mixing of the co-solvent in the sample and improve the mixing degree of the sample. In addition, in the present application, by arranging the stirring rod 320 to rotate in the opposite direction to the container with the rotating motor 310, the contact probability between the stirring rod 320 and the sample during the mixing process can also be increased, thereby further improving the stirring effect of the stirring device and ensuring the accuracy of the sample during the experiment.

[0030] In some feasible embodiments of the present application, the stirring rod 320 is linear and is made of a bio-inert polymer material of a polymer composite material, such as polyurethane, to improve the wear resistance of the stirring rod 320 and ensure the durability of the stirring rod 320 .

[0031] In some embodiments of the present application, the stirring rod 320 is linear, and the stirring rod 320 consists of a main body and a branch part, the branch part includes a plurality of cross bars, the main body extends along the extension direction of the stirring rod 320, the branch part is arranged on the main body, and the plurality of cross bars extend in a direction perpendicular to the stirring rod 320 to further improve the stirring effect of the stirring rod 320 and improve the uniformity of sample mixing.

[0032] In some other embodiments of the present application, the stirring rod 320 is eccentrically arranged with respect to the output shaft. With the above arrangement, when the container is tilted, the stirring rod 320 will be closer to the inner wall of the container during the rotation with the output shaft, thereby preventing some materials from not being stirred by the stirring rod 320 during the stirring process of the stirring rod 320, and further improving the stirring effect of the stirring device.

[0033] In some embodiments of the present application, there is a certain angle between the extension direction of the stirring rod 320 and the axis of the container. Such a setting can increase the stirring range of the stirring rod 320, thereby improving the mixing effect of the stirring rod 320 on the sample.

[0034] Furthermore, the stirring rod 320 may be directly connected to the rotating motor 310 or may be connected via a connecting rod, which is not specifically limited in the present application.

[0035] In some other embodiments of the present application, the stirring rod 320 is tilted in the vertical direction, and the angle formed between the stirring rod 320 and the vertical direction is the same as the angle between the axis of the container and the vertical direction. Such a configuration can ensure that the stirring rod 320 can be as close to the inner wall of the container as possible during the stirring process, thereby preventing part of the sample from being deposited between the stirring rod 320 and the inner wall of the container, thereby improving the stirring effect of the stirring device.

[0036] In the present application, the stirring device further includes a driving assembly 330, which is drivingly connected to the rotating motor 310 and is used to drive the rotating motor 310 to move relative to the container, and the moving track of the rotating motor 310 driven by the driving assembly 330 has an angle in the vertical direction. The driving assembly 330 can drive the stirring rod 320 to move relative to the container in the container. During the stirring process, the above arrangement can fully prevent the sample from being stratified, and further improve the mixing effect of the sample.

[0037] Specifically, the included angle of the moving trajectory of the driving assembly 330 driving the rotating motor 310 in the vertical direction and the included angle of the container in the vertical direction can be the same or different, and there is no specific limitation in the present application.

[0038] In a specific embodiment of the present application, the driving assembly 330 includes a driving motor, a lead screw and a fixed block. The lead screw is connected to the driving motor, the driving motor can drive the lead screw to rotate, the lead screw is tilted in the vertical direction, the fixed block is threaded with the lead screw, and the rotating motor 310 is fixedly arranged on the fixed block. Through the above arrangement, the driving motor drives the lead screw to rotate, and the fixed block can move along the extension direction of the lead screw. It only needs to adjust the direction of the driving motor to make the fixed block reciprocate along the lead screw, thereby driving the rotating motor 310 to reciprocate relative to the container, so as to improve the mixing effect of the stirring device on the sample.

[0039] In other embodiments of the present application, the driving component 330 may also be configured as a gear module or a transmission wheel module, as long as it can drive the rotating motor 310 to move.

[0040] Specifically, the inclination angle of the container in the vertical direction is between 45° and 60°. When the inclination angle of the container in the vertical direction is less than 45°, the inclination angle is too small, and part of the material may still not move relative to the container under the action of gravity during the mixing process, and the effect of forcing the sample to flow is poor; when the inclination angle of the container in the vertical direction is greater than 60°, the inclination angle is too large, and the capacity of the container to accommodate the sample is reduced, affecting the stirring efficiency of the sample. In the present application, by setting the inclination angle of the container in the vertical direction between 45° and 60°, the stirring effect can be guaranteed while ensuring the stirring efficiency. Specifically, the inclination angle of the container in the vertical direction can be set to 45°, 50°, 55° or 60°.

[0041] Specifically in the present application, the installation assembly 200 includes a clamping assembly and a rotating cylinder 210. The clamping assembly is used to clamp the container, and the clamping assembly is arranged at one end of the rotating cylinder 210. The clamping assembly can rotate under the drive of the rotating cylinder 210, and the rotating cylinder 210 is arranged tilted in the vertical direction. Through the above arrangement, the clamping assembly can clamp the container to achieve the installation of the container. Compared with the conventional method in which the stirring device is usually provided with a stirring tank to accommodate the sample, the present application clamps the material through the clamping assembly, which can reduce the loss of the sample during the transfer process and improve the working efficiency of the mixing work.

[0042] In a specific embodiment of the present application, the clamping assembly includes a plurality of clamping jaws 220, which are arranged at one end of the rotating cylinder 210 in an annular manner, and one end of the clamping jaws 220 is hinged to the rotating cylinder 210, and the plurality of clamping jaws 220 cooperate with each other to clamp the container. Through the above arrangement, the plurality of clamping jaws 220 can cooperate together to clamp the container to ensure the stability of the clamping assembly clamping the container. Specifically, there is a locking structure between the plurality of clamping jaws 220 and the rotating cylinder 210 to prevent the plurality of clamping jaws 220 from loosening due to centrifugal force during the rotation of the rotating cylinder 210, so as to ensure the stability of the container installed on the clamping assembly.

[0043] Specifically, the clamping jaw 220 can be hingedly connected to the rotating cylinder 210 via a rotating shaft, so as to adjust the angle of the clamping jaw 220 relative to the rotating cylinder 210, thereby facilitating the picking up and placing of the container.

[0044] Furthermore, a fixing ring is provided between the clamping jaws 220 and the rotating cylinder 210. When the multiple clamping jaws 220 cooperate to clamp the container, the fixing ring can be sleeved on the outer periphery of the multiple clamping jaws 220 to ensure the clamping effect of the clamping assembly. The fixing ring can be a hoop or other structure, so that the clamping assembly can be adapted to containers of different diameters, thereby increasing the application range of the installation assembly 200.

[0045] In the present application, the rotary cylinder 210 is movably arranged on the support base 100 to adjust the height of the container in the vertical direction. Through the above arrangement, the position of the container can be adjusted by adjusting the rotary cylinder 210, so that the relative position of the container with respect to the stirring assembly 300 can be adjusted. When the container is large or the stirring rod 320 is long, the rotary cylinder 210 can be adjusted to be further away from the stirring assembly 300; when the container is small or the stirring rod 320 is short, the rotary cylinder 210 can be adjusted to be closer to the stirring assembly 300, so as to improve the applicability of the stirring device.

[0046] In some embodiments of the present application, a mounting track is provided between the rotating cylinder 210 and the support seat 100, and the rotating cylinder 210 is movably provided on the mounting track, and a fastener is also provided between the mounting track and the rotating cylinder 210 to limit the relative position of the rotating cylinder 210 relative to the mounting track. Through the above arrangement, the position of the rotating cylinder 210 on the mounting track can be adjusted to adjust the relative position of the rotating cylinder 210 relative to the stirring assembly 300, and the rotating cylinder 210 and the mounting track are locked by the fastener to prevent the rotating cylinder 210 from being displaced during the stirring process, thereby ensuring the stable operation of the stirring device.
