Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge that is convenient for observation. Background Art

[0002] Centrifuges are often used in the biomedical field. The high-speed rotation of the centrifuge is used to separate some structures within the cell to obtain the required finished product. When in use, the centrifuge tubes are placed symmetrically on the rotor rotating disk, covered with a protective cover, and then the machine is started for centrifugation.

[0003] Chinese patent CN221016638U discloses a cell centrifuge, comprising a centrifuge, a sealing cover hingedly connected to one side of the centrifuge by a hinge, a sealing gasket bonded to the surface of the sealing cover, a groove provided on the surface of the centrifuge, a placement plate provided inside the groove, and a plurality of placement slots provided on the surface of the placement plate.

[0004] However, the existing device still has the following problems: it is inconvenient to observe the centrifugal degree of the centrifuge tubes in the device during operation, which makes it difficult to observe the changes in the solutions in the centrifuge tubes during the centrifugation process. When placing an odd number of centrifuge tubes, the operator sometimes forgets to place the balance tube or places the centrifuge tubes in the wrong position, so that the centrifuge tubes are not placed symmetrically on the rotor, causing the centrifuge to shake due to imbalance during operation, posing a safety hazard.

[0005] Based on this, the utility model designs a centrifuge that is easy to observe to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a centrifuge that is easy to observe.

[0012] The synchronous downward moving assembly is arranged inside the rotor. There are multiple synchronous downward moving assemblies and they are evenly distributed along a straight line. The synchronous downward moving assembly is used to restrict the operator to place the centrifuge tubes symmetrically and synchronously on the rotor.

[0014] Furthermore, the dehumidification mechanism includes a hot air component and a liquid outlet component, the hot air component is arranged on the top of the centrifuge, and the liquid outlet component is arranged on the outer wall of the centrifuge.

[0015] Furthermore, the hot air assembly includes an air ring and an air port. The air ring is fixedly connected to the top of the centrifuge through a straight rod, and the air port is fixedly installed on the bottom surface of the air ring. There are multiple air ports evenly arranged on the air ring along the circumferential direction.

[0016] Furthermore, the liquid outlet assembly includes a collecting ring and a liquid outlet hole. The collecting ring is fixedly connected to the outer wall of the centrifuge.

[0021] Furthermore, the high-strength transparent cover is configured as high-strength organic glass.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The synchronous downward movement assembly mechanism allows the operator to place the centrifuge tubes in the rotor holes only when they are placed symmetrically and synchronously.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0035] Example 1

[0036] In some embodiments, please refer to the appendix of the specification. Figure 1-6 , a centrifuge convenient for observation, comprising a centrifuge 1;

[0037] A high-strength transparent cover 5 is rotatably connected to the top of the centrifuge 1 for observing the internal conditions of the centrifuge 1;

[0038] A dehumidification mechanism 2 is provided on the top of the centrifuge 1 for removing moisture from the centrifuge 1;

[0039] A rotor 3 for placing centrifuge tubes is rotatably mounted on the top of the centrifuge 1, and a foolproof mechanism 4 is provided inside the rotor 3 to prevent operational errors.

[0040] The foolproof mechanism 4 includes a synchronous downward movement component 41 and a locking component 42;

[0041] The synchronous downward moving assembly 41 is disposed inside the rotor 3. A plurality of synchronous downward moving assemblies 41 are provided and evenly distributed along a straight line. The synchronous downward moving assembly 41 is used to restrict the operator to place the centrifuge tubes symmetrically and synchronously on the rotor 3.

[0042] The locking assembly 42 is disposed inside the rotor 3 , and is used to limit the synchronous downward moving assembly 41 .

[0043] When the utility model is in use, the mechanism of the synchronous downward moving assembly 41 allows the operator to place the centrifuge tubes intactly in the holes of the rotor 3 only when the centrifuge tubes are placed symmetrically and synchronously. Otherwise, the centrifuge tubes cannot be inserted into the holes of the rotor 3, thereby preventing the operator from starting the machine when there are too few centrifuge tubes or when the centrifuge tubes are placed in the wrong position. The utility model conspicuously reminds the operator and avoids the safety hazards caused by operational errors. The hot air from the outside is connected to the dehumidification mechanism 2, so that the hot air is blown out from the dehumidification mechanism 2. The hot air will heat and blow the water in the centrifuge 1, causing the water to flow out or evaporate, which is beneficial to keeping the device dry and avoiding rust inside the device. The inside of the centrifuge 1 can be directly observed through the high-strength transparent cover 5.

[0044] The dehumidification mechanism 2 includes a hot air component 21 and a liquid outlet component 22. The hot air component 21 is arranged on the top of the centrifuge 1, and the liquid outlet component 22 is arranged on the outer wall of the centrifuge 1.

[0045] The hot air assembly 21 includes an air ring 211 and an air port 212. The air ring 211 is fixedly connected to the top of the centrifuge 1 through a straight rod. The air port 212 is fixedly installed on the bottom surface of the air ring 211. There are multiple air ports 212 evenly arranged along the circumferential direction of the air ring 211.

[0046] The liquid outlet assembly 22 includes a collecting ring 221 and a liquid outlet hole 222. The collecting ring 221 is fixedly connected to the outer wall of the centrifuge 1. The liquid outlet hole 222 is opened at the bottom of the collecting ring 221 and multiple liquid outlet holes 222 are evenly arranged on the collecting ring 221 along the circumferential direction.

[0047] When it is necessary to remove the water inside the centrifuge 1, the air inlet of the air ring 211 is connected to the external hot air pipe, and the hot air is discharged from the outlet of the air port 212 and blown into the centrifuge 1, so that the water inside the centrifuge 1 evaporates, and part of the water is discharged from the liquid outlet 222 under the action of the wind, thereby achieving the cleaning of the water inside the centrifuge 1. After the cleaning is completed, the air ring 211 is separated from the external heat pipe;

[0048] A cavity 31 is formed inside the rotor 3, and a rotor inner sleeve 32 is fixedly connected to the inside of the rotor 3;

[0049] The synchronous downward movement component 41 includes a thin ring 411, a crossbar 412, a collar 413 and a spring 414. Multiple thin rings 411 are sleeved on the rotor inner sleeve 32, and the height decreases from top to bottom. The outer wall of the thin ring 411 is symmetrically fixedly connected to the crossbar 412. The outer end of the crossbar 412 is fixedly connected to the collar 413. The collar 413 is in sliding contact with the hole of the rotor 3. The bottom surface of the crossbar 412 is fixedly connected to the spring 414. The other end of the spring 414 is fixedly connected to the bottom surface of the cavity 31.

[0050] The locking assembly 42 includes a vertical rod 421, a through slot 422, and a blocking slot 423. The vertical rod 421 is fixedly connected to the bottom surface of the cavity 31, and multiple vertical rods 421 are evenly arranged along the circumferential direction. The through slot 422 and the blocking slot 423 are opened on the cross bar 412.

[0051] The vertical rods 421 are respectively located directly below the plurality of through slots 422;

[0052] After the centrifuge tube is placed in the hole of the rotor 3, it will contact and rub against the collar 413 to achieve mutual friction and adsorption between the centrifuge tube and the collar 413;

[0053] The high-strength transparent cover 5 is set to high-strength organic glass;

[0054] High-strength organic glass specifically refers to glass made of polymethyl acrylate;

[0055] When the operator places two symmetrical centrifuge tubes in the holes of the rotor 3 at the same time and presses down, the cross bars 412 on both sides of the thin ring 411 will not be deflected, so the vertical rod 421 will slide with the through groove 422 and make the thin ring 411 drop vertically, so that the centrifuge tube can drop synchronously with the ring 413. When the centrifuge tube is taken out, the thin ring 411 and the cross bar 412 are reset under the action of the spring 414. If the operator does not place the centrifuge tube symmetrically or puts the centrifuge tube in the wrong position, it will cause the centrifuge tube to be placed only in the wrong position. In the collar 413 on one side of the single thin circular ring 411, due to the principle of lever force deflection, the cross bar 412 on one side of the thin circular ring 411 will rotate, so that the blocking groove 423 slides into contact with the top of the vertical rod 421, so that the blocking groove 423 presses against the vertical rod 421, causing the collar 413 to be stuck, thereby preventing the centrifuge tube from being placed intact in the hole of the rotor 3, thereby clearly reminding the operator that the placement position of the centrifuge tube needs to be changed due to operational errors, thereby avoiding safety hazards caused by inaccurate placement of the centrifuge tube.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
