Description

Technical Field

[0001] This utility model belongs to the field of centrifuge technology, and in particular relates to a laboratory centrifuge. Background Technology

[0002] In scientific research and experimental fields such as chemistry and biology, centrifuges are indispensable equipment in the process of separating substances. This equipment separates substances by placing the experimental substances to be separated into centrifuge tubes, arranging these centrifuge tubes evenly and symmetrically inside the centrifuge, and then starting the centrifuge to rotate at high speed.

[0003] However, the existing centrifuges have fixed-size tube slots, which means they cannot accommodate centrifuge tubes of different diameters. This limitation means that when researchers need to separate experimental materials from tubes that are too thick or too thin, they have to use centrifuges of different sizes, resulting in poor versatility. Utility Model Content

[0004] This invention provides a laboratory centrifuge, aiming to solve the problem mentioned in the background art that existing centrifuges have poor versatility because they cannot be used with centrifuge tubes of different diameters.

[0005] To solve the above problems, this utility model is implemented as follows: a laboratory centrifuge includes: a first housing, on which a second housing is fixedly mounted; a circular plate rotatably mounted on the second housing, on which multiple cylinders are fixedly mounted, each cylinder being used to hold centrifuge tubes containing experimental substances; multiple annular air bladders fixedly mounted on the inner walls of the multiple cylinders for fixing the centrifuge tubes; multiple heating plates fixedly mounted on the bottom inner wall of the second housing for heating the centrifuge tubes; a support tube rotatably mounted on the second housing, the top end of the support tube being fixedly connected to the bottom of the circular plate; multiple connecting tubes fixedly mounted on the support tube, one end of each connecting tube extending into the interior of the multiple annular air bladders; a gas supply mechanism mounted on the first housing for filling and releasing gas; and a rotating mechanism mounted on the second housing for rotating the support tube.

[0006] Preferably, the air supply mechanism includes: an air pump fixedly installed on the inner wall of the bottom of the first housing, a through pipe fixedly installed on the exhaust end of the air pump, the through pipe being rotatably and sealingly connected to the inner wall of the support pipe; and an exhaust pipe fixedly installed on the through pipe, the exhaust pipe being provided with a solenoid valve.

[0007] Preferably, the rotating mechanism includes: a motor fixedly mounted on the bottom of the second housing, with a first bevel gear fixedly sleeved on the output shaft of the motor; and a second bevel gear fixedly sleeved on the support tube, the second bevel gear meshing with the first bevel gear.

[0008] Preferably, a plurality of anti-slip pads are fixedly installed on the bottom of the first housing, and all of the anti-slip pads are made of rubber.

[0009] Preferably, the first housing has multiple first through holes on both sides, and the second housing has a cover hinged to it.

[0010] Preferably, a temperature sensor is fixedly installed on one side of the second housing, and the detection probe of the temperature sensor extends into the interior of the second housing, while a controller is fixedly installed on one side of the first housing.

[0011] Preferably, the bottom of each of the multiple cylinders is provided with multiple second through holes, and the multiple cylinders are all inclined.

[0012] Compared with related technologies, the experimental centrifuge provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, the experimental centrifuge provided by this solution uses an air supply mechanism that allows multiple annular air bladders to continuously expand. These air bladders can fix centrifuge tubes of different diameters within multiple cylinders, ensuring stability during centrifugation and greatly improving the equipment's versatility. Furthermore, the air bladders can be deflated after operation. The rotating mechanism allows a circular plate to drive multiple cylinders to rotate, enabling centrifugation of experimental substances in multiple tubes and separating them. Multiple heating plates allow the experimental substances in the tubes to be heated simultaneously during centrifugation, shortening the experimental process. The separated substances do not need to be transferred to a heating device for further heating, resulting in better performance. If heating is not required, the heating plates are not necessary.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a laboratory centrifuge, such as Figure 1-4As shown, the experimental centrifuge includes: a first housing 1, on which a second housing 2 is fixedly mounted; a circular plate 3 rotatably mounted on the second housing 2, on which multiple cylinders 4 are fixedly mounted, each of which is used to hold centrifuge tubes containing experimental substances; multiple annular air bladders 5 fixedly mounted on the inner walls of the multiple cylinders 4 for fixing the centrifuge tubes; multiple heating plates 6 fixedly mounted on the bottom inner wall of the second housing 2 for heating the centrifuge tubes; a support tube 7 rotatably mounted on the second housing 2, the top end of which is fixedly connected to the bottom of the circular plate 3; multiple connecting tubes 18 fixedly mounted on the support tube 7, one end of which extends into the interior of the multiple annular air bladders 5; a gas supply mechanism mounted on the first housing 1 for filling and releasing gas; and a rotating mechanism mounted on the second housing 2 for rotating the support tube 7.

[0022] In this embodiment, when using this device to separate experimental substances, the cover 16 is first opened, and then the experimental substances from multiple centrifuge tubes are inserted into multiple cylinders 4. After insertion, the gas supply mechanism is activated. The gas supply mechanism can use the support tube 7 to supply gas to multiple connecting tubes 18, which in turn supply gas to multiple annular air bladders 5, causing the annular air bladders 5 to expand continuously. This allows the centrifuge tubes in the multiple cylinders 4 to be fixed, enabling the fixing of centrifuge tubes of various thicknesses. This ensures that the centrifuge tubes remain stable during centrifugation, greatly improving the versatility of the device. After the centrifuge tubes are fixed, the cover 16 is closed, and the rotation mechanism is activated. The rotation mechanism drives the support tube 7 to rotate, which in turn drives the circular plate 3 to rotate on the second housing 2. The circular plate 3 drives the multiple cylinders 4 to rotate, thereby centrifuging the experimental substances in the multiple centrifuge tubes and separating the substances. During the centrifugation process, several heating plates 6 can be activated as needed to heat the experimental substances, thus shortening the experimental process. The final separated substances do not need to be transferred to a heating device for further heating, resulting in better performance.

[0023] In a further preferred embodiment of the present invention, the air supply mechanism includes: an air pump 8 fixedly installed on the inner wall of the bottom of the first housing 1, a through pipe 9 fixedly installed on the exhaust end of the air pump 8, the through pipe 9 being rotatably and sealingly connected to the inner wall of the support pipe 7; and an exhaust pipe 10 fixedly installed on the through pipe 9, the exhaust pipe 10 being provided with a solenoid valve 11.

[0024] In this embodiment, the gas supply mechanism is used to fill and release gas. When in use, the air pump 8 is started, and the air pump 8 delivers gas to the support pipe 7 through the pipe 9. The support pipe 7 delivers gas to multiple connecting pipes 18, and the multiple connecting pipes 18 deliver gas to multiple annular air bladders 5, causing the multiple annular air bladders 5 to expand continuously. This allows the centrifuge tubes in the multiple cylinders 4 to be fixed, enabling the fixing of centrifuge tubes of various thicknesses. This ensures that the centrifuge tubes remain stable during centrifugation, greatly improving the versatility of the equipment. When the equipment is finished and it is necessary to release the fixing of the multiple centrifuge tubes, the solenoid valve 11 is opened. After the solenoid valve 11 is opened, the gas in the multiple annular air bladders 5 will be discharged from the exhaust pipe 10. After discharge, it is convenient for the operator to remove the multiple centrifuge tubes from the multiple cylinders 4.

[0025] In a further preferred embodiment of the present invention, the rotating mechanism includes: a motor 12 fixedly installed at the bottom of the second housing 2, a first bevel gear 13 fixedly sleeved on the output shaft of the motor 12; and a second bevel gear 14 fixedly sleeved on the support tube 7, the second bevel gear 14 meshing with the first bevel gear 13.

[0026] In this embodiment, the rotating mechanism is used to rotate the support tube 7. When in use, the motor 12 is started, and the motor 12 drives the first bevel gear 13 to rotate. The first bevel gear 13 drives the second bevel gear 14 to rotate, and the second bevel gear 14 drives the support tube 7 to rotate. The support tube 7 drives the circular plate 3 to rotate on the second housing 2, and the circular plate 3 drives multiple cylinders 4 to rotate, thereby centrifuging the experimental substances in multiple centrifuge tubes to separate the substances.

[0027] In a further preferred embodiment of the present invention, a plurality of anti-slip pads 15 are fixedly installed on the bottom of the first housing 1, and the plurality of anti-slip pads 15 are all made of rubber.

[0028] In this embodiment, the rubber anti-slip pad 15 has good elasticity and friction, which can effectively increase the friction between the first housing 1 and the placement surface, thereby improving the stability of the device during operation.

[0029] In a further preferred embodiment of the present invention, a plurality of first through holes are provided on both sides of the first housing 1, and a cover 16 is hinged to the second housing 2.

[0030] In this embodiment, the cover 16 can provide dust and water protection for the circular plate 3 and multiple cylinders 4, and the multiple first through holes can ensure that the air pump 8 has enough gas to operate, so as to prevent excessive negative pressure from being generated inside the first housing 1.

[0031] In a further preferred embodiment of the present invention, a temperature sensor 17 is fixedly installed on one side of the second housing 2, and the detection probe of the temperature sensor 17 extends into the interior of the second housing 2. A controller is fixedly installed on one side of the first housing 1.

[0032] In this embodiment, the temperature sensor 17 and the controller work together to detect the temperature inside the second housing 2, which allows the operator to use the heating plate 6 to heat the inside of the second housing 2 to a suitable operating temperature so that the experimental material can be heated.

[0033] In a further preferred embodiment of the present invention, a plurality of second through holes are provided at the bottom of the plurality of cylinders 4, and the plurality of cylinders 4 are inclined.

[0034] In this embodiment, by using multiple second through holes, heat from the second shell 2 can enter multiple cylinders 4, thereby heating multiple centrifuge tubes.

[0035] In summary, compared with related technologies, this solution, through the use of an air supply mechanism, allows multiple annular air bladders 5 to continuously expand, enabling them to fix centrifuge tubes of different diameters within multiple cylinders 4. This ensures the stability of the centrifuge tubes during centrifugation, greatly improving the equipment's versatility. Furthermore, the annular air bladders 5 can be deflated after operation. The rotating mechanism allows the circular plate 3 to drive the multiple cylinders 4 to rotate, enabling the centrifugation of experimental substances in multiple centrifuge tubes and achieving substance separation. The use of multiple heating plates 6 allows the experimental substances in the centrifuge tubes to be heated simultaneously during centrifugation, thus shortening the experimental process. The separated substances do not need to be transferred to a heating device for further heating, resulting in better performance. If heating is not required, the heating plates 6 are not necessary.
