It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When a component is considered to be "connected" to another component, it can be directly connected to the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 and 2, the present utility model provides an oscillating mixing device 100, which includes a base 10, a first driving member 20 and a clamping assembly 40.

The structure of the base 10 is not limited, and the base 10 is a supporting foundation for other structures. In an application environment, the base 10 may be placed directly on the floor or on another counter. Preferably, the base 10 should have a stable structure, adjustable level and shock-proof properties, so as to ensure the stability of the machine in working conditions.

The first driving member 20 is mounted to the base 10. The first drive member 20 may be a motor including, but not limited to, a DC motor, an AC motor, a brushed motor, a brushless motor, an asynchronous motor, a synchronous motor, etc. Preferably, the first driving member 20 is a stepping motor. The first driving member 20 has a first driving shaft and a first driving body, which are rotatably connected, and the first driving body is capable of driving the first driving shaft to perform a rotation motion with its axis. Preferably, the axial direction of the first driving shaft is parallel to the plate surface of the base 10.

Optionally, the vibration mixing device 100 further includes a first fixing base a, where the first fixing base a is erected on the base 10, and the first driving member 20 is fixedly installed on the first fixing base a. The clamping assembly 40 is located at a side of the first fixing seat a facing away from the first driving member 20, and the first driving shaft passes through the first fixing seat a to be connected with the clamping assembly 40.

The clamping assembly 40 is connected to the first driver 20. The clamping assembly 40 may be used to clamp a container, preferably a centrifuge tube, test tube, or the like.

The clamping assembly 40 is deformable for clamping containers of different sizes. It will be appreciated that the clamping assembly 40 may have a plurality of components that are movable relative to one another so that the clamping assembly 40 may have different configurations. Therefore, the clamping assembly 40 having deformability may be understood as a state of the clamping assembly 40 when a plurality of parts are at different positions. The clamping assembly 40 is provided with deformability, so that the clamping assembly 40 can adapt to containers (centrifuge tubes) with different sizes, and the vibration mixing device 100 provided by the utility model can have universality.

The first driving member 20 drives the clamping assembly 40 to rotate in a preset rotation state. The first driving member 20 may be electrically connected to a controller, where the controller may be an intelligent terminal such as a computer, a tablet computer, or a mobile phone. The mode of operation of the first driver 20 can be preset by the controller. It is understood that the operation mode of the first driving member 20 is the operation mode of the clamping assembly 40, and the operation mode is understood as a rotating state. Depending on the desired requirements of the sample, the user may give different rotational status instructions to the first driver 20 via the controller. The working condition which is preset on the controller and is output to the first driving member 20 by the controller is a preset rotation state.

Alternatively, the preset rotation state may be that the first driving member 20 drives the clamping assembly 40 to rotate continuously around the first direction. The first direction may be a counterclockwise direction or a clockwise direction.

In other embodiments, the preset rotation state may be that the first driving member 20 drives the clamping assembly 40 to rotate in a pendulum manner. For example, the centrifuge tube is held vertically by the holding assembly 40 on a horizontal plane basis. The clamp assembly 40 may be rotated 45 deg. clockwise, then 90 deg. counter-clockwise, then 90 deg. clockwise. Thus, the periodic pendulum type rotation is presented. By adopting pendulum type vertical oscillation, better mixing effect can be achieved by simulating the oscillating track of a human hand.

In other embodiments, the preset rotation state may be that the first driving member 20 drives the clamping assembly 40 to rotate at a fixed rotation time or a rotation angle. Preferably, in the initial state, the clamping assembly 40 clamps the container in a vertical state. The workbench surface is used as a horizontal plane, the container is a centrifuge tube, and the axial direction of the centrifuge tube is vertical to the horizontal plane, namely, the centrifuge tube is kept in a vertical state.

The utility model provides the vibration mixing device 100, which can be used for mixing samples in the pretreatment process of pesticide residues and medicine residues QuEChERS. According to the device, the first driving piece 20 is arranged on the base 10, the clamping assembly 40 is driven by the first driving piece 20 to rotate in a preset rotating state, so that containers clamped by the clamping assembly 40 can be mixed at a uniform speed, the rotating frequency and the rotating mode of the clamping assembly 40 can be controlled through the preset rotating state, and the device can be suitable for uniformly mixing more different samples, and the mixing efficiency is high and the mixing effect of the samples is good due to the high mechanization degree of the device; meanwhile, the clamping assembly 40 provided by the utility model has deformability, and can adapt to containers with different shapes and sizes through deformation, so that the device has universality and can provide more effective mixing effect for different containers.

In one embodiment, referring to fig. 2, the clamping assembly 40 includes a first clamping member 41 and a second clamping member 42; the first clamping member 41 is connected with the first driving member 20; the second clamping piece 42 is movably connected with the first clamping piece 41; the second clamping member 42 can be moved away from or toward the first clamping member 41 to clamp or unclamp the container.

Specifically, the first clamping member 41 and the second clamping member 42 may be disposed in order along the axial direction of the first drive shaft. The first clamping member 41 is fixedly connected with the first driving member 20, and the second clamping member 42 is movably connected with the first clamping member 41. Optionally, the second clamping member 42 is movably connected with the first clamping member 41, including but not limited to, being an elastic connection, a sliding connection, a detachable connection, etc., to thereby achieve deformability of the clamping assembly 40.

For example, when the second clamping member 42 is elastically connected to the first clamping member 41, an elastic mechanism may be disposed between the second clamping member 42 and the first clamping member 41, and the elastic mechanism elastically deforms to enable the second clamping member 42 to be away from the first clamping member 41, and returns to enable the second clamping member 42 to be close to the first clamping member 41. It will be appreciated that when the second clamping member 42 is in resilient connection with the first clamping member 41, the resilient mechanism may deform to allow the clamping assembly 40 to clamp the container and further increase the amount of resilient deformation to remove the container.

When the second clamping member 42 is slidably connected with the first clamping member 41, a sliding mechanism may be provided between the second clamping member 42 and the first clamping member 41, and the second clamping member 42 or the first clamping member 41 may slide through the sliding mechanism. Of course, when the second clamping member 42 is detachably connected to the first clamping member 41, the second clamping member 42 may be connected to the first clamping member 41 by a snap or other fitting assembly, and the container may be removed after the second clamping member 42 is removed.

In the present embodiment, the specific positional relationship of the second clamping member 42 and the first clamping member 41 may not be limited. It can be understood that the first clamping member 41 and the second clamping member 42 are configured to jointly clamp the container, and the first clamping member 41 and the second clamping member 42 can relatively move, so that the clamping assembly 40 can adapt to containers with different specifications, and the vibration mixing device 100 provided by the utility model can have universality.

By providing the first clamping member 41 and the second clamping member 42, and providing the second clamping member 42 in a movable manner, the user can clamp or unclamp the container by controlling the distance or approach of the second clamping member 42, thereby improving the convenience of the device.

In one embodiment, referring to fig. 2 and 3, the clamping assembly 40 further includes a guide post 43, one end of the guide post 43 is fixedly connected to one of the first clamping member 41 and the second clamping member 42, the other end of the guide post 43 is slidably connected to the other of the first clamping member 41 and the second clamping member 42, and the second clamping member 42 moves away from or near the first clamping member 41 along the axial direction of the guide post 43 to clamp or unclamp the container.

In particular, the axial direction of the guide post 43 may be parallel to the axial direction of the first drive shaft. The first clamping member 41 and the second clamping member 42 may be sequentially disposed in the axial direction. The guide post 43 can be used for connecting the first clamping piece 41 and the second clamping piece 42, and when the first driving piece 20 drives the first clamping piece 41 to rotate, the guide post 43 can drive the second clamping piece 42 to synchronously rotate; the guide posts 43 may in turn be used to provide a guiding action for the second clamping member 42 as it approaches or moves away from the first clamping member 41. It is to be understood that the shape of the guide post 43 is not particularly limited, and may be a cylindrical shape or a polygonal column.

Alternatively, the number of the guide posts 43 may be plural. The axial direction of the plurality of guide posts 43 is parallel to the axial direction of the first drive shaft. The provision of the plurality of guide posts 43 has an advantage in that it is possible to improve the smoothness when the second clamping member 42 moves, and also to secure the stability when the first and second clamping members 41 and 42 clamp the container.

Preferably, the number of the guide posts 43 is two, and the two guide posts 43 are disposed left and right in a direction perpendicular to the axial direction. The containers are thus positioned between the first clamping member 41 and the second clamping member 42, respectively, and between the two guide posts 43 when they are secured. This ensures that the container is constrained in four directions and that stability during oscillation is ensured.

Through setting up guide post 43 between first holder 41 and second holder 42, utilize guide post 43 to restrict the direction of movement of second holder 42 for the mutual motion between first holder 41 and the second holder 42 can be more firm, and utilize guide post 43 to cooperate with first holder 41 and second holder 42, the fixed container that can be better, the steadiness of container when guaranteeing the vibration mixing.

In one embodiment, referring to fig. 3, one end of the guide post 43 is fixedly connected to the first clamping member 41, the clamping assembly 40 further includes a guide post bearing 44, the guide post bearing 44 is connected to the second clamping member 42, and the second clamping member 42 is movably connected to the guide post 43 through the guide post bearing 44.

Specifically, one end of the guide post 43 is fixedly connected to a surface of the first clamping member 41 facing away from the first driving member 20, and extends in a direction away from the first driving member 20. The second clamping member 42 may be provided with through holes penetrating through two opposite sides of the second clamping member 42, and then the through holes are penetrated by the guide posts 43, so that the second clamping member 42 may be sleeved on the guide posts 43.

Optionally, the clamping assembly 40 further includes a guide post bearing 44, where the guide post bearing 44 is connected to the perforated inner wall and sleeved on the outer periphery of the guide post 43, and the second clamping member 42 is slidably connected to the guide post 43 through the guide post bearing 44.

In one embodiment, one end of the guide post 43 is fixedly connected to the second clamping member 42 (not shown in the figure), the clamping assembly 40 further includes a guide post bearing 44, the guide post bearing 44 is connected to the first clamping member 41, and the second clamping member 42 and the guide post 43 are movably connected to the first clamping member 41 through the guide post bearing 44.

Specifically, one end of the guide post 43 is fixedly connected to a surface of the second clamping member 42 facing the first clamping member 41, and extends in a direction away from the second clamping member 42 (which may be understood as an integral structure of the guide post 43 and the second clamping member 42). The first clamping member 41 may be provided with through holes penetrating through opposite sides of the first clamping member 41, and then the through holes are penetrated by the guide posts 43, so that the first clamping member 41 may be sleeved on the guide posts 43.

Optionally, the clamping assembly 40 further includes a guide post bearing 44, where the guide post bearing 44 is connected to the perforated inner wall and sleeved on the outer periphery of the guide post 43, and the second clamping member 42 and the guide post 43 are slidably connected to the first clamping member 41 through the guide post bearing 44. As can be appreciated, since the first clamping member 41 is fixed to the base 10 by the first driving member 20, the first clamping member 41 is fixed, and the guide post 43 slides relative to the first clamping member 41, thereby driving the second clamping member 42.

In an embodiment, referring to fig. 4, the first clamping member 41 includes a first clamping surface 41A facing away from the first driving member 20, the first clamping surface 41A includes at least two sub-clamping surfaces, any two adjacent sub-clamping surfaces are connected at an obtuse angle, the first clamping surface 41A has an axisymmetric structure, and the symmetry axis is perpendicular to the axis of the guide post 43.

Alternatively, the first clamping surface 41A may be formed by a first sub-clamping surface 411 and a second sub-clamping surface 412 of the first clamping member 41 facing away from the first driving member 20. The first clamping member 41 may be a block of cubic shape. One face of which is connected to the first driving member 20 and the opposite face of which is recessed in the direction of the first driving member 20 to form a first clamping face 41A. The projection of the first clamping surface 41A on the base 10 may be "V" shaped, i.e. composed of the first sub-clamping surface 411 and the second sub-clamping surface 412 together.

Alternatively, the first sub-clamping surface 411 and the second sub-clamping surface 412 may be planar, so that the axis of the guide post 43 may have an angle with both the first sub-clamping surface 411 and the second sub-clamping surface 412. It will be appreciated that, since the centrifuge tube is mostly a cylindrical container, the contact area between the first clamping member 41 and the centrifuge tube can be increased by providing the first clamping member 41 with the first sub-clamping surface 411 and the second sub-clamping surface 412 having an included angle, so that the stability of clamping the centrifuge tube by the clamping assembly 40 can be increased. In addition, the first sub-clamping surface 411 and the second sub-clamping surface 412 are connected through an obtuse angle, so that centrifuge tubes with different diameter sizes can be matched, and compatibility of the device is improved.

Optionally, the first clamping surface 41A may further include a third sub-clamping surface (not shown in the figure), where the third sub-clamping surface connects the first sub-clamping surface 411 and the second sub-clamping surface 412, respectively, and the first sub-clamping surface 411 and the second sub-clamping surface 412 are connected with the third sub-clamping surface at an obtuse angle. It will be appreciated that the projection of the first clamping surface 41A on the base 10 may be substantially "︺", i.e. consist of the first sub-clamping surface 411, the third sub-clamping surface and the second sub-clamping surface 412 together. By providing the first sub-clamping surface 411, the third sub-clamping surface and the second sub-clamping surface 412 with an included angle, the contact surface between the first clamping member 41 and the container can be increased, so that the contact area can be increased to achieve a better clamping and fixing effect.

Alternatively, the first clamping surface 41A may also be a smooth curved surface, i.e. the projection of the first clamping surface 41A on the base 10 may be a smooth arc. In other embodiments, the first clamping surface 41A may further be formed of two or more discontinuous arc surfaces, i.e. the projection of the first clamping surface 41A on the base 10 may be a non-smooth multi-segment arc. Alternatively, the first clamping surface 41A may be a combination of a plane surface and an arc surface, which is not limited by the present utility model.

In one embodiment, referring to fig. 4, the second clamping member 42 includes a second clamping surface 42A facing the first clamping member 41, and the second clamping surface 42A is identical in structure to the first clamping surface 41A and is opposite to the first clamping surface 41A.

Alternatively, the second clamping surface 42A may be composed of a fourth sub-clamping surface 421 and a fifth sub-clamping surface 422 of the second clamping member 42 facing the first clamping member 41. The second clamping member 42 may be initially in the form of a cube-shaped block. Which is recessed toward one face of the first clamping member 41 to form a second clamping face 42A. The projection of the second clamping surface 42A on the base 10 may be "V" shaped, i.e. composed of the fourth sub-clamping surface 421 and the fifth sub-clamping surface 422 together.

Alternatively, the fourth sub-clamping surface 421 and the fifth sub-clamping surface 422 may each be planar, so that the axis of the guide post 43 may have an angle with respect to both the fourth sub-clamping surface 421 and the fifth sub-clamping surface 422. It will be appreciated that since the centrifuge tube is mostly a cylindrical container, the contact area between the second clamping member 42 and the centrifuge tube can be increased by providing the fourth sub-clamping surface 421 and the fifth sub-clamping surface 422 with an included angle on the second clamping member 42, so that the stability of clamping the centrifuge tube by the clamping assembly 40 can be increased.

Preferably, the first sub-clamping surface 411 and the fourth sub-clamping surface 421 are opposite and parallel, and the second sub-clamping surface 412 is opposite and parallel to the fifth sub-clamping surface 422. The benefit of this arrangement is that when the second clamping member 42 approaches the first clamping member 41, the range between the second clamping member 42 and the first clamping member 41 is limited, so that the four surfaces can be abutted against the centrifuge tube, and the centrifuge tube and the clamping assembly 40 are abutted and fixed.

By arranging four faces to fix the container, the abutting area between the clamping assembly 40 and the container can be increased, so that the fixing stability of the clamping assembly 40 to the container is maximized; and by utilizing four flat surfaces to abut the container, the clamping assembly 40 can have greater versatility and can be adapted to a variety of different diameter sizes of containers (centrifuge tubes or test tubes).

Optionally, the second clamping surface 42A may further include a sixth sub-clamping surface (not shown in the figure), where the sixth sub-clamping surface connects the fourth sub-clamping surface 421 and the fifth sub-clamping surface 422, respectively, and each of the fourth sub-clamping surface 421 and the fifth sub-clamping surface 422 forms an obtuse angle with the sixth sub-clamping surface. It will be appreciated that the projection of the second clamping surface 42A on the base 10 may be substantially "︺", i.e. be composed of the fourth sub-clamping surface 421, the sixth sub-clamping surface and the fifth sub-clamping surface 422 together.

In the embodiment of the present utility model, the first clamping surface 41A and the second clamping surface 42A have the same structure and are disposed opposite to each other, and the first clamping surface 41A and the second clamping surface 42A have axisymmetric structures, and their symmetry axes are parallel to each other and perpendicular to the axis of the guide post 43. The projection of the first clamping surface 41A on the base 10 and the projection of the second clamping surface 42A on the base 10 are also axisymmetric, and the symmetry axes thereof are coincident and parallel to the axis of the guide post 43. This arrangement ensures that the first clamping surface 41A and the second clamping surface 42A are sufficiently stable to hold the container together and that the container is uniformly stressed.

In one embodiment, a flexible pad is provided on first clamping surface 41A and/or second clamping surface 42A.

Alternatively, the bodies of the first clamping member 41 and the second clamping member 42 may be made of metal or plastic, and then after the first clamping surface 41A and the second clamping surface 42A are formed, a soft material (flexible pad) may be wrapped on the clamping surfaces, so that the contact area with the container is soft. Therefore, friction force is increased, the containers can be protected, and some fragile containers are prevented from being deformed and crushed after being extruded.

Alternatively, soft materials include, but are not limited to, rubber, silicone, latex, and the like. Of course, in other embodiments, the first clamping surface 41A and the second clamping surface 42A may also be wrapped with an air cushion, such as an inflatable bag, aerogel, or sponge.
