[0001] The utility model relates to the technical field of stirring appliances for experimental containers, in particular to a portable mixing device. Background Art
[0002] When analyzing and testing liquid samples in experiments, it is usually necessary to mix the samples by stirring so that the substances are evenly distributed. Currently, commonly used mixing devices are usually blenders or homogenizers.
[0003] However, in actual use, the stirring components in a mixing device such as a blender or homogenizer can only exert stirring force in the horizontal height direction. Due to the limited working space, when the sample liquid level in the container is high or there is a lot of sedimentation, the blender or homogenizer cannot mix it well. In addition, when the blender or homogenizer is used to stir the liquid sample in the container, the liquid sample may splash out. For this reason, this patent designs a portable stirring device. Utility Model Content
[0004] Based on the above description, the present invention provides a portable mixing device, which solves the technical problems that the existing mixing device cannot apply stirring force in the horizontal and vertical directions at the same time, and the liquid sample is easily splashed during stirring.
[0005] The utility model solves the above technical problems with the following technical solutions: A portable mixing device comprising:

[0008] The disc has a center hole formed thereon and is movably connected to the outer side of the shaft through the center hole, so that the mixing component 2 can simultaneously complete the rotation and lifting actions to exert stirring forces in vertical and horizontal directions.
[0009] On the basis of the above technical solution, the present invention can also be improved as follows.
[0010] Furthermore, the shaft column and the sleeve are both hollow at the top and bottom to reduce the weight of the shaft column and the sleeve.
[0011] Furthermore, the second mixing component also includes a positioning sleeve, which is detachably connected to the outside of the shaft column. The sleeve is located below the positioning sleeve. A fixing piece is provided at the bottom of the shaft column. The cross-section of the fixing piece is convex. When the cover contacts the bottom of the positioning sleeve, the fixing piece can limit the sleeve for easy carrying.
[0012] Furthermore, the fixing member is a rubber plug, which is snap-fitted to the shaft column.
[0013] Furthermore, the fixing member is a limiting bolt, which is threadedly connected to the shaft column.
[0014] Furthermore, a fluid replenishing bucket is fixed to the top end of the shaft column, and a cover is provided at the inlet of the fluid replenishing bucket, so that the operator can replenish fluid from the fluid replenishing bucket.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0028] like Figure 1-4 As shown, a portable mixing device in this embodiment is mainly used in a laboratory to stir and mix the sample liquid in a laboratory container. The container here refers to a container with an open upper opening, including a mixing part 1, a mixing part 2 and a disc 3, wherein the mixing part 1 and the mixing part 2 can be connected in a lifting manner, so that the application of the vertical stirring force can be completed. When the mixing part 2 2 is rotated, the mixing part 1 can be driven to rotate. In this way, the portable mixing device can apply stirring force in the horizontal and vertical directions at the same time. As for the disc 3, it is placed on the top of the container during use. The disc 3 does not affect the normal stirring of the mixing part 1 and the mixing part 2, and can prevent the sample liquid from splashing and prevent foreign matter from entering the container.
[0029] In order to facilitate understanding of the structural relationship and function of the mixing component 1, the mixing component 2 and the disc 3, a detailed description is given here. First, as shown in FIG. Figure 1 、 2 As shown in FIG4 , the mixing component 1 includes a sleeve 11 and a mixing paddle 12 , wherein the mixing paddle 12 is fixed on the outside of the sleeve 11 , and a notch 13 is provided on the outside of the sleeve 11 .
[0030] Secondly, the mixing component 2 includes a shaft column 21, a fixed sleeve 22 and a mixing paddle 23, wherein the shaft column 21 is slidably connected to the inner side of the sleeve 11, forming a lifting relationship between the mixing component 1 and the mixing component 2. The fixed sleeve 22 is detachably connected to the outer side of the shaft column 21, and the diameter of the fixed sleeve 22 is equal to the inner diameter of the sleeve 11. The mixing paddle 23 is fixed to the outer side of the fixed sleeve 22 and is slidably connected to the inner side of the notch 13. In this way, when the mixing component 2 is rotated, the mixing component 1 can be driven to rotate, ensuring that the portable mixing device can apply stirring force in the horizontal and vertical directions at the same time.
[0031] It should be noted that, initially, the shaft column 21 and the lower surface of the sleeve 11 are flush, and the notch 13 extends vertically downward from the top surface of the sleeve 11, and a cover 14 is detachably provided on the sleeve 11. The cover 14 is fixed to the sleeve 11 by bolts, and the cover 14 is used to prevent the mixing paddle 23 from falling out of the notch 13.
[0032] As for disk 3, Figure 3 As shown, a center hole is opened on the disk 3, and the disk 3 is movably connected to the outer side of the shaft column 21 through the center hole, so that the shaft column 21 can complete the rotation and lifting movements at the same time, and the mixing component 2 2 applies stirring forces in the vertical and horizontal directions. In this way, the normal stirring of the mixing component 1 and the mixing component 2 is not affected. In practice, the disk 3 is placed on the top of the container, which can prevent the sample liquid from splashing and prevent foreign matter from entering the container.
[0033] During operation, pulling up the shaft column 21 can change the height position of the mixing paddle 23, thereby changing its stirring position in the container. In this way, when the shaft column 21 is pulled up and rotated, the portable mixing device can apply stirring force in the horizontal and vertical directions at the same time through the mixing paddle 23 and the mixing paddle 12.
[0034] In addition, if Figure 3 As shown, a handle 6 is fixed to the outside of the shaft column 21. The cross-section of the handle 6 is in the shape of a circular U, which can be held by the operator for easy carrying. The handle 6 has a threaded hole, which is provided at the inner bottom wall of the handle 6. A locking bolt is threadedly connected in the threaded hole. At this time, a limiting hole is provided on the disc 3. When designed in this way, when the locking bolt is threadedly connected to the limiting hole, the disc 3 can be locked to the bottom of the handle 6, thereby making the portable mixing device easier to carry when in use.
[0035] To further facilitate portability, in one embodiment, Figure 3 As shown, the shaft column 21 and the sleeve 11 are both hollow at the top and bottom to reduce the weight of the shaft column 21 and the sleeve 11.
[0036] Further, such as Figure 4As shown, the mixing component 2 further includes a positioning sleeve 24, which is detachably connected to the outer side of the shaft column 21. In order to understand the detachable connection relationship between the positioning sleeve 24 and the fixing sleeve 22 and the shaft column 21, it should be noted that, as shown in FIG. Figure 1 and 2 As shown, the outer sides of the positioning sleeve 24 and the fixing sleeve 22 are both provided with assembly holes 25 , and fixing bolts threadedly connected to the shaft column 21 are provided in the assembly holes 25 .
[0037] The sleeve 11 is located below the positioning sleeve 24. In order to limit and lock the sleeve 11 or the mixing component 1 as a whole when the sleeve 11 abuts against the positioning sleeve 24, a fixing part 4 is detachably provided at the bottom of the shaft column 21. The cross-section of the fixing part 4 is convex. When the cover 14 abuts against the bottom of the positioning sleeve 24, the fixing part 4 can limit the sleeve 11 for carrying.
[0038] There are many ways to implement the fixing member 4. For example, in one embodiment, the fixing member 4 is a rubber plug, which is snap-fitted to the shaft column 21. It should be noted that at this time, the maximum diameter of the fixing member 4 is larger than the inner diameter of the sleeve 11. In this way, since the cross-section of the fixing member 4 is convex, when the protruding part of the rubber plug is fully snapped onto the inner side of the shaft column 21, the sleeve 11 is limited between the rubber plug and the positioning sleeve 24. At this time, since the sleeve 11 is completely located on the outside of the shaft column 21, the overall height is relatively small, which can provide convenience for carrying the portable mixing device.
[0039] It can be understood that in another embodiment, the fixing member 4 can be, for example, a limiting bolt, which is threadedly connected to the shaft column 21. Similarly, the sleeve 11 is limited between the limiting bolt and the positioning sleeve 24. At this time, since the sleeve 11 is completely located on the outside of the shaft column 21, the overall height is relatively small, which can provide convenience for carrying the portable mixing device.
[0040] Considering that the experimental container needs to be replenished with liquid during the stirring process, the mixing component 1, the mixing component 2 and the disc 3 need to be replaced after being removed as a whole. Therefore, in a certain embodiment, Figure 3 As shown, a fluid replenishing bucket 5 is fixed to the top of the shaft column 21, and a cover is provided at the inlet of the fluid replenishing bucket 5. The cover and the fluid replenishing port are preferably threadedly connected. After the cover is removed by rotating, the operator can replenish fluid from the fluid replenishing bucket 5.
[0041] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
