[0029] Reference Figures 1 to 2 This embodiment provides a shaking device for uniformly mixing a collection cup 51, comprising a mounting base 1, a reciprocating drive device, a flipping drive device, a sliding fit mechanism, and a collection cup fixing mechanism. The reciprocating drive device is fixed by the mounting base 1 and drives the collection cup fixing mechanism to reciprocate on the sliding fit mechanism. The flipping drive device is fixed by the sliding fit mechanism and drives the collection cup fixing mechanism to flip at a certain angle. The sliding fit mechanism is fixed by the mounting base 1, and the collection cup fixing mechanism is fixed by the sliding fit mechanism.

[0030] It should be noted that the collection cup 51 with the collected specimen is fixed on the collection cup fixing mechanism to ensure that the collection cup 51 is firmly fixed, and under the drive of the reciprocating drive device, the collection cup 51 will not fall off the collection cup fixing mechanism, wherein the flipping drive device and the collection cup fixing mechanism are both fixed by a sliding matching mechanism and perform reciprocating motion together. The flipping drive device controls the collection cup fixing mechanism to flip a certain angle according to the set program to achieve directional photography of the specimen and control the cup cover upward and downward.

[0031] In this embodiment, the reciprocating drive device includes a reciprocating drive motor 21, a reciprocating crankshaft 22 and a reciprocating connecting rod 23, the sliding matching mechanism includes a sliding guide rail 41 and a sliding connecting plate 42, the flipping drive device includes a flipping drive motor 31, the reciprocating drive motor 21 is fixed through the mounting base plate 1, the first end of the reciprocating crankshaft 22 is connected to the output end of the reciprocating drive motor 21, and the second end is hinged to the first end of the reciprocating connecting rod 23, the second end of the reciprocating connecting rod 23 is hinged to the sliding connecting plate 42, the sliding connecting plate 42 is slidably connected to the sliding guide rail 41, the collection cup fixing mechanism is fixed by the sliding connecting plate 42, and can be flipped along the connection position between it and the sliding connecting plate 42, and the sliding guide rail 41 is fixed to the mounting base plate 1.

[0032] Driven by the reciprocating drive motor 21 and conducted by the reciprocating crankshaft 22 and the reciprocating connecting rod 23, the sliding connecting plate 42 reciprocates on the sliding guide rail 41, and the sliding connection between the sliding guide rail 41 and the sliding connecting plate 42 can reduce friction and improve the conversion efficiency of the motor. The flipping drive motor 31 and the collection cup fixing mechanism are both fixed by the sliding connecting plate 42, and the output shaft of the flipping drive motor 31 is transmission-connected to the collection cup fixing mechanism. The collection cup fixing mechanism and the sliding connecting plate 42 are fixed by a connecting shaft. Under the action of the flipping drive motor 31, the collection cup fixing mechanism flips at a certain angle with the connecting shaft as the center.

[0033] In this embodiment, the collection cup fixing mechanism includes a fixed back plate 52, a mounting base plate 53 is provided at the bottom of the fixed back plate 52, and a clamping device is provided at the top. The mounting base plate 53 is provided with two limit baffles 54 that cooperate with the collection cup 51 to limit the position. The fixed back plate 52 can be flipped along the connection position between the fixed back plate 52 and the sliding connecting plate 42 under the drive of the flip drive motor 31, and the collection cup 51 is placed on the mounting base plate 53 and clamped between the two limit baffles 54, so that the collection cup 51 is limited in the left and right directions. It is then fixed by the clamping device, and a pressing force is applied from top to bottom to cooperate with the mounting base plate 53, so that the collection cup 51 is limited in the up and down directions.

[0034] In this embodiment, the clamping device includes a limiting pressure plate 55, a reset device and two guide columns 56. The guide columns 56 are fixed on the top of the fixed back plate 52. A limiting hole corresponding to the guide column 56 is provided on the limiting pressure plate 55. The limiting pressure plate 55 is sleeved on the guide column 56 through the clearance between the limiting hole and the guide column 56. Under the action of the reset device, the limiting pressure plate 55 is automatically reset to be fixed to the collection cup 51; a clearance hole 59 is also provided on the limiting pressure plate 55. Since the limiting pressure plate 55 is fixed with respect to the cup cover of the collection cup 51, a sealing soft rubber is provided on the cup cover of the collection cup 51. The injection needle or sampling needle can be manually operated to pierce the sealing soft rubber through this clearance hole 59 to fill the collection cup 51 with liquid or take samples.

[0035] As a first preferred solution, the reset device is a reset spring 57 corresponding to the guide column 56. A limiting boss is provided at the free end of the guide column 56. The reset spring 57 is sleeved on the guide column 56. One end of the reset spring 57 is connected to the limiting boss and the other end is connected to the limiting pressure plate 55. By utilizing the elastic force of the reset spring 57, when the limiting pressure plate 55 moves upward and compresses the reset spring 57, the elastic force increases, so that the limiting pressure plate 55 is always subjected to a downward pressure, effectively fixing the collection cup 51 in the collection cup fixing mechanism.

[0036] As a second preferred solution, the reset device includes a pair of electromagnets, which include a first electromagnet and a second electromagnet. The first electromagnet is fixed to the top of the fixed back plate 52, and the second electromagnet is fixed to the limit pressure plate 55. The first electromagnet and the second electromagnet are in a mutually attractive state. Due to the magnetic attraction of the electromagnets, the limit pressure plate 55 is always subjected to a downward pressure, effectively fixing the collection cup 51 in the collection cup fixing mechanism.

[0037] As a third preferred solution, the reset spring 57 and the electromagnet are combined to use double pressure for protection. When the collection cup 51 is about to separate from the mounting base 53, it will be subjected to the combined action of elastic force and magnetic attraction, making the fixation of the collection cup 51 more stable.

[0038] The present invention also provides a method for using the shaking device according to the above embodiment, comprising the following steps:

[0039] Step S1: placing the collection cup 51 in the collection cup fixing mechanism and fixing the collection cup 51;

[0040] Step S2: After the collection cup 51 is fixed, the lid is facing upwards, and the sealing soft rubber on the lid is pierced with an injection needle, and an appropriate amount of liquid is added;

[0041] Step S3: controlling the reciprocating drive device to drive the collection cup fixing mechanism to reciprocate under the restriction of the sliding fit mechanism to perform a shaking action;

[0042] Step S4: After the shaking action stops, the flip driving device is controlled to drive the collection cup fixing mechanism to flip 180 degrees and then let it stand;

[0043] Step S5: After the standing time, pierce the sealing rubber on the cup lid with a sampling needle and take a sample;

[0044] Step S6: withdraw the sampling needle, control the flip driving device, drive the collection cup fixing mechanism to flip 180 degrees, and take out the collection cup 51.

[0045] It should be noted that an impact point is provided in the collection cup 51, and this impact point is provided at the bottom of the collection cup 51 and the inner wall of the cup cover. Driven by the reciprocating drive device, the collection cup fixing mechanism performs reciprocating motion. By utilizing inertia, the liquid in the collection cup 51 drives the specimen to impact and collide in all directions in the collection cup 51. When the specimen hits the impact point, it will be subjected to force and gradually soften or be diluted, and this process is completed completely in a sealed state, and will not cause any leakage of the specimen. In addition, when adding liquid to the collection cup 51, the puncture depth of the injection needle only needs to be slightly larger than the thickness of the sealing soft rubber on the cup cover, ensuring that the needle tip of the injection needle is still a certain distance away from the liquid surface after the liquid is added, avoiding direct contact between the injection needle and the specimen, and reducing the risk of cross contamination.

[0046] After the shaking stops, the tilting drive is controlled to drive the collection cup fixing mechanism to flip 180 degrees and then rest. At this time, the cup lid and the soft sealing rubber of the collection cup 51 face downward. Due to the filter screen provided in the collection cup 51, during the resting process, the specimen is filtered by the filter screen due to gravity and sinks to the inner wall of the cup lid. The sampling needle is then operated from bottom to top to pierce the soft sealing rubber and take the sample. During this process, due to the reasonable thickness of the soft sealing rubber, it can achieve natural healing and sealing. After puncture and retraction, the material in the collection cup 51 can also be sealed and stored.

[0047] Compared with the prior art, the present invention provides a shaking device, including a mounting base 1, a reciprocating drive device, a flipping drive device, a sliding fit mechanism and a collection cup fixing mechanism. The reciprocating drive device is fixed by the mounting base 1 and drives the collection cup fixing mechanism to reciprocate on the sliding fit mechanism. The flipping drive device is fixed by the sliding fit mechanism and drives the collection cup fixing mechanism to flip at a certain angle. The sliding fit mechanism is fixed by the mounting base 1, and the collection cup fixing mechanism is fixed by the sliding fit mechanism.

[0048] The present invention also provides a method of use, wherein a collection cup 51 is secured by a collection cup securing mechanism, a reciprocating drive mechanism is controlled to drive the collection cup securing mechanism to reciprocate, and a flipping drive mechanism is controlled to flip the collection cup securing mechanism 180°. During this shaking process, the specimen remains sealed within the collection cup 51, enabling contactless shaking. The present invention features a simple structure and reliable sealing, significantly reducing the possibility of specimen leakage and contamination or even infection of the office environment. Furthermore, by controlling the flipping drive mechanism to flip the collection cup securing mechanism at a certain angle, directional photography of the specimen is achieved.

[0049] Finally, it should be emphasized that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only preferred embodiments of the present invention and are not intended to limit the present invention.
