[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 1-3 As shown, this embodiment proposes a constant temperature magnetic stirrer for processing medical device test samples, including a base 1, a stirring box 4 fixed on the top of the base 1, a stir bar 5 installed on the top of the base 1, a positioning component 2 installed on the outside of the stir bar 5, and an adjustment component 3 sleeved on the outside of the stir bar 5.

[0027] Positioning component 2 includes positioning ring 21, with a threaded groove 22 at the bottom of positioning ring 21, a connector 23 threadedly connected to the threaded groove 22, a sealing cap 24 fixed at the bottom of connector 23, and a protrusion 25 at the bottom of sealing cap 24.

[0028] The top of the mixing tank 4 is provided with a positioning groove 26, and a magnetic block 27 is fixed in the positioning groove 26. A limit ring 28 is fixed at the center of the shaft inside the mixing tank 4. An adjustment groove 29 is provided in the limit ring 28. Positioning blocks 210 are slidably connected to both the upper and lower ends of the adjustment groove 29. A connecting block 211 is fixed to one end of the positioning block 210. A sliding block 212 is slidably connected to the side of the connecting block 211, so that the stirring element 5 can be further positioned, thereby preventing the stirring element 5 from jumping during the mixing process.

[0029] A support block 213 is fixed to the side of the connecting block 211, and a spring 214 is fixed to the side of the support block 213. The other end of the spring 214 is fixed in the adjustment groove 29. The spring 214 is used to enable the positioning block 210 to automatically reset when the stir bar 5 is disengaged from the limiting ring 28.

[0030] The side of the connecting block 211 closest to the sliding block 212 is inclined, and the sliding block 212 is trapezoidal, so that the sliding block 212 can press against the connecting block 211.

[0031] The surface of the positioning block 210 is smooth, so that when the positioning block 210 is in contact with the stir bar 5, the stir bar 5 can achieve the effect of magnetic stirring.

[0032] In this embodiment, when the stir bar 5 is needed to stir the solution in the stirring tank 4, the sealing cap 24 is fitted onto the stir bar 5 and threaded onto the bottom of the positioning ring 21 through the connector 23, so that the sealing cap 24 is fixed to the bottom of the positioning ring 21. Then, the stir bar 5 is moved to the top of the stirring tank 4 and moved downward. When the bottom of the stir bar 5 moves into the limiting ring 28, the sealing cap 24 is magnetically attracted to the magnetic block 27 on the top of the stirring tank 4 through the protrusion 25, so that the stirring tank 4 can be sealed, thereby preventing the solution from splashing during the stirring process. When the stir bar 5 moves into the limiting ring 28, the stir bar 5 pushes the bottom positioning block 210 into the adjusting groove 29. The connecting block 211 on the side of the positioning block 210 pushes the sliding block 212 to push the top positioning block 210 outward, thereby further positioning the stir bar 5 and preventing the stir bar 5 from jumping during the stirring process.

[0033] Example 2

[0034] like Figures 4-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the adjustment component 3 includes a collar 31, a rotating ring 32 is rotatably connected inside the collar 31, a drive gear 33 is fixed at the bottom of the rotating ring 32, a connecting gear 34 is meshed with the side of the drive gear 33, a rotating shaft 35 is fixed at the bottom of the connecting gear 34, and a blade 36 is fixed on the outside of the rotating shaft 35.

[0035] There are two sets of blades 36, which are staggered on both sides of the collar 31. The blades 36 are triangular. When the two sets of blades 36 are unfolded, the shape of the stir bar 5 changes to a rhombus, which can adapt to the stirring of solutions of different concentrations. The blades 36 are plastic and are made of rubber.

[0036] The outer side of the collar 31 has a groove that matches the blade 36. A buckle is installed on the side of the collar 31 near the groove, so that the blade 36 can be fixed in the groove of the collar 31, thereby making the stirrer 5 cylindrical.

[0037] In this embodiment, when it is necessary to stir a solution with a high concentration, the blade 36 is first pressed out of the groove in the collar 31. Then, the rotating ring 32 can be rotated so that the drive gear 33 at the bottom of the rotating ring 32 meshes with the connecting gear 34, thereby causing the blade 36 fixed on the rotating shaft 35 to unfold outward, so that the external shape of the stirrer 5 becomes rhomboid, which is suitable for stirring solutions with a high concentration.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
