[0020] like Figure 2 As shown, this embodiment provides a vortex mixer, which includes a device body 1, a base plate 2 and a sponge base 3 connected in sequence. The top of the sponge base 3 is provided with multiple insertion holes for placing test tubes. The vortex mixer also includes a covering component 4 for covering the test tubes.

[0021] Specifically, such as Figure 2 , Figure 5 , Figure 6As shown, the pressure-covering assembly 4 includes a base 41, a sleeve 42, a cover plate 44, an adjusting rod 43, a spring 45, and a first spring 46. The adjusting rod 43, spring 45, and first spring 46 are all housed within the sleeve 42. The base 41 is located on the outer wall of the equipment body 1. To facilitate installation or disassembly of the pressure-covering assembly 4, the base 41 is fixedly connected to the equipment body 1 by multiple screws 412. The top of the base 41 has a through groove 411, which can penetrate the base 41 vertically or horizontally. A sleeve 42 is vertically fixed to the top of the base 41 through the base 41. The side wall of the sleeve 42 is provided with a first through hole 421 and a second through hole 422. The first through hole 421 is located below the second through hole 422. A cover plate 44 covers the top of the test tube. The bottom end of the control rod 43 passes through the through groove 411. The top end of the control rod 43 is connected to the cover plate 44. The bottom end of the spring piece 45 is connected to the outer wall of the control rod 43. The top end of the spring piece 45 is provided with a limiting block 451, which is locked in the first through hole 421.

[0022] After the vortex mixer has completed high-speed mixing, the experimenter presses the limiting block 451 with his hand and makes it disengage from the first through hole 421. The first spring 46 can move the control rod 43 upward until the limiting block 451 is locked to the second through hole 422. During this process, the cover plate 44 also moves upward with the control rod 43 so as to remove the test tube in the sponge seat 3.

[0023] To facilitate the removal of the limiting block 451 from the first through hole 421, this embodiment adopts the following measures: Figure 6 As shown, a pressing element 5 is provided at the first through hole 421 on the outer wall of the sleeve 42. The pressing element 5 includes a base 51 and a pressing rod 52. The base 51 is fixedly connected to the sleeve 42. The pressing rod 52 passes through the base 51, and the inner end of the pressing rod 52 is aligned with the first through hole 421. A button 53 is provided at the outer end of the pressing rod 52. A second spring 54 is provided on the outer periphery of the pressing rod 52. The two ends of the second spring 54 are connected to the button 53 and the base 51. The experimenter only needs to press the button 53 to disengage the limiting block 451 from the first through hole 421.

[0024] After removing the previously mixed test tubes from the sponge holder 3, place the new batch of test tubes to be mixed into the sponge holder 3. The control rod 43 and cover plate 44 can be lowered in two ways: First, the experimenter presses the limiting block 451 inside the second through hole 422 with one hand to disengage it from the second through hole 422, while pressing down on the control rod 43 and cover plate 44 with the other hand. A "click" sound indicates that the limiting block 451 is locked inside the first through hole 421. The second method is the preferred method. Figure 6 As shown, the bottom surface of the limiting block 451 is set as an inclined surface. During operation, you only need to press down the adjusting rod 43 and the cover plate 44 directly, and the limiting block 451 will be automatically squeezed out of the second through hole 422.

[0025] The specific structure of the control lever 43 is as follows: Figure 4 , Figure 5 As shown, the control lever 43 includes a first lever 431, a second lever 432, and a third lever 433 from bottom to top. The diameter of the first lever 431 is smaller than the diameter of the second lever 432, and the diameter of the second lever 432 is smaller than the diameter of the third lever 433. The bottom end of the spring piece 45 is connected to the outer wall of the second lever 432. The first spring 46 is located on the outer periphery of the first lever 431 and is connected to the second lever 432 and the base 41 respectively.

[0026] To restrict the control rod 43 from rotating freely within the sleeve 42, and to ensure that the control rod 43 can only move up and down within the sleeve 42, such as... Figure 2 , Figure 4 As shown, the side wall of the third rod 433 is cut into a first plane at a symmetrical position, and the inner wall of the sleeve 42 is set as a second plane at a corresponding position. The first plane is in close contact with the second plane to limit the rotation of the control rod 43.

[0027] To minimize the vertical movement of the cover plate 44 while still allowing for easy placement or removal of the test tube from the sponge holder 3, this embodiment employs the following measures: Figure 4 , Figure 5 As shown, the top of the third rod 433 is provided with a groove 434, and the cover plate 44 is provided with a protrusion 441 on the side facing the third rod 433. The protrusion 441 is located in the groove 434 and is hinged to the adjusting rod 43. Figure 4 As shown, the cover plate 44 remains horizontal. The experimenter can flip the cover plate 44 to the other side of the control lever 43 by hand. It should be noted here that... Figure 4 There are many ways to keep the cover plate 44 horizontal. For example, a cylindrical stop bar can be set in the groove 434, with the stop bar positioned more towards one side of the cover plate 44 within the groove 434. The stop bar is located below the protruding plate 441 and is used to support the cover plate 44 to maintain its horizontal position without affecting the flipping of the cover plate 44. After flipping the cover plate 44, it is easier to place the test tube into the sponge seat 3 or remove the test tube. Figure 5 As shown, at this time, the cover plate 44 covers the test tube, and the bottom surface of the convex plate 441 is in close contact with the top surface of the sleeve 42 to restrict the cover plate 44 from flipping. When the experimenter presses the button 53, the limiting block 451 is disengaged from the first through hole 421, and the first spring 46 causes the adjusting rod 43 and the cover plate 44 to move upward until the limiting block 451 is locked to the second through hole 422. At this time, the cover plate 44 is released from restriction and can be flipped.
