Description

Technical Field

[0001] This utility model belongs to the field of centrifuge technology, specifically relating to a benchtop high-speed centrifuge. Background Technology

[0002] A high-speed centrifuge is a laboratory device widely used in scientific research and production fields such as biology, chemistry, medicine, and agriculture to separate, extract, and concentrate various components in samples. Its working principle is based on the centrifugal force generated by high-speed rotation, which causes particles in suspensions or mixtures to settle, thereby achieving separation.

[0003] A known authorized patent with application number CN201920276418.3 discloses a benchtop high-speed centrifuge: including a casing, top cover, control panel, power supply, centrifuge chamber, drive device, and cooling device. An ultraviolet lamp electrically connected to the control panel is installed on the inner side of the top of the casing. The cooling device includes a water tank and a pressure device at the water tank outlet located outside the casing, a speed control device, and a spiral condenser tube that cooperates with the outer wall of the centrifuge chamber. The spiral condenser tube is fixed inside the casing by I-beam screws. The condenser tube inlet and outlet are connected to the water tank outlet and inlet respectively via pipes. The pressure device and speed control device are connected to the control panel. A pipe through-hole and a temperature sensor electrically connected to the control panel are provided on the right side of the casing.

[0004] However, the following problems were found in the implementation of the relevant technology: the device does not have a door locking structure, and opening the centrifuge by hand while the centrifuge is still running may injure the staff. In addition, the device cannot detect the speed of the centrifuge. If the centrifuge speed is too high and the centrifuge rotor becomes unbalanced, the centrifuge rotor may fly out and cause injury to personnel.

[0005] Therefore, a benchtop high-speed centrifuge is proposed to solve the above problems. Utility Model Content

[0006] This invention proposes a benchtop high-speed centrifuge, which solves the problem in related technologies that centrifuges cannot detect the centrifuge speed and the balance of the centrifuge rotor.

[0007] The technical solution of this utility model is as follows: A benchtop high-speed centrifuge, comprising: a chassis, a water tank, and a control box;

[0008] A motor is fixedly installed on the bottom surface inside the chassis, a centrifugal rotor is fixedly installed at the output end of the motor, a test tube groove is opened inside the centrifugal rotor, and an inner liner is fixedly installed inside the chassis.

[0009] An infrared rangefinder is fixedly installed on the inner bottom surface of the inner liner, a temperature detector is fixedly installed on the inner bottom surface of the inner liner, a spiral condenser is fixedly installed on the inner wall of the inner liner, an ultraviolet lamp is fixedly installed inside the inner liner, and a tachometer is fixedly installed inside the chassis.

[0010] The chassis has a hinged top cover inside, the water tank has a motor fixedly installed inside, the output end of the motor has a rotating drum fixedly installed, the outside of the rotating drum has a magnet fixedly installed, the chassis has a sliding groove inside, and a magnetic slider is slidably arranged inside the sliding groove.

[0011] Preferably, a partition is fixedly installed inside the water tank, a vacuum pump is fixedly installed on the top of the partition, and a water pumping pipe is fixedly installed at the output end of the vacuum pump.

[0012] Preferably, a display module is fixedly installed on the top of the control box, and a control module is fixedly installed on the top of the control box.

[0013] Preferably, the positive pole of the magnetic slider is located near the rotating drum, and there are two magnets on the rotating drum, with one magnet having its positive pole facing outward and the other having its negative pole facing outward.

[0014] Preferably, the infrared rangefinder is located directly below the centrifugal rotor, and the light beam of the infrared rangefinder shines directly below the centrifugal rotor.

[0015] Preferably, the distance between the magnetic slider and the inner liner is greater than the thickness of the top cover.

[0016] The working principle and beneficial effects of this utility model are as follows: By making one positive pole and one negative pole of the two magnets on the rotating drum face outwards, the magnetic slider can slide inside the groove when the drum rotates, thereby blocking the top cover and preventing the operator from opening the top cover before the centrifuge stops. By shining the beam of the infrared rangefinder directly below the centrifuge rotor, the balance of the centrifuge rotor can be monitored in real time, preventing the centrifuge rotor imbalance from affecting the centrifugation efficiency or damaging the centrifuge. By fixing the vacuum pump on the top of the partition, the coolant inside the water tank can enter the spiral condenser to cool the centrifuge when the vacuum pump is started, preventing the centrifuge temperature from being too high and affecting the samples to be centrifuged. By making the distance between the magnetic slider and the inner liner greater than the thickness of the top cover, the magnetic slider can lock the top cover when it is closed.

[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] Implementation

[0026] Please see Figure 1 -5, a benchtop high-speed centrifuge, comprising: a chassis 1, a water tank 2, and a control box 3;

[0027] A motor 4 is fixedly installed on the bottom surface inside the casing 1. A centrifugal rotor 5 is fixedly installed at the output end of the motor 4. A test tube groove 6 is opened inside the centrifugal rotor 5. An inner liner 7 is fixedly installed inside the casing 1.

[0028] An infrared rangefinder 8 is fixedly installed on the bottom surface of the inner liner 7, a temperature detector 9 is fixedly installed on the bottom surface of the inner liner 7, a spiral condenser tube 10 is fixedly installed on the inner wall of the inner liner 7, an ultraviolet lamp 11 is fixedly installed inside the inner liner 7, and a tachometer 23 is fixedly installed inside the chassis 1.

[0029] The chassis 1 has a hinged top cover 12 inside. The water tank 2 has a motor 13 fixedly installed inside. The output end of the motor 13 has a rotating drum 14 fixedly installed. The outside of the rotating drum 14 has a magnet 15 fixedly installed. The chassis 1 has a sliding groove 16 inside. A magnetic slider 17 is slidably arranged inside the sliding groove 16.

[0030] The technical solution provided in this embodiment is as follows: In use, firstly, the test tube containing the sample is placed inside the test tube slot 6, then the top cover 12 is closed, and then the motor 13 is started to rotate the rotating drum 14 so that the positive pole of the magnet 15 on the rotating drum 14 is aligned with the magnetic slider 17. Then the magnetic slider 17 slides inside the slide groove 16, thereby moving the magnetic slider 17 to the top of the top cover 12 and blocking the top cover 12. Then the motor 4 is started to rotate the centrifugal rotor 5 to centrifuge the sample inside the test tube. When the centrifugal rotor 5 rotates, the tachometer 23 records the rotation speed of the centrifugal rotor 5 and then displays it on the display module 21. When the rotation speed of the centrifugal rotor 5 is too high, the power output to the motor 4 is reduced to reduce the rotation speed of the centrifugal rotor 5. The infrared rangefinder 8 detects the distance between the centrifugal rotor 5 and the infrared rangefinder 8 in real time. When the centrifugal rotor 5 tilts, the display module 21 will alarm and then stop the motor 4 to prevent the centrifuge from being damaged due to instability when the centrifugal rotor 5 rotates.

[0031] Furthermore, a partition 18 is fixedly installed inside the water tank 2, a vacuum pump 19 is fixedly installed on the top of the partition 18, and a water pumping pipe 20 is fixedly installed at the output end of the vacuum pump 19.

[0032] Specifically, by fixing the vacuum pump 19 to the top of the partition 18, the coolant inside the water tank 2 can enter the spiral condenser tube 10 to cool the centrifuge when the vacuum pump 19 is started, preventing the centrifuge temperature from being too high and affecting the sample to be centrifuged.

[0033] Furthermore, a display module 21 is fixedly installed on the top of the control box 3, and a control module 22 is fixedly installed on the top of the control box 3.

[0034] Specifically, by fixing the display module 21 and the control module 22 to the top of the control box 3, the centrifuge can be controlled to operate through the control module 22 and the display module 21.

[0035] Furthermore, the positive pole of the magnetic slider 17 is located near the rotating cylinder 14, which has two magnets 15, with one magnet facing outward and the other facing outward.

[0036] Specifically, by having one positive pole of the two magnets 15 on the rotating drum 14 face outward and the other negative pole face outward, the magnetic slider 17 can slide inside the slide groove 16 when the rotating drum 14 is rotating, thereby blocking the top cover 12 and preventing the staff from opening the top cover 12 before the centrifuge stops.

[0037] Furthermore, the infrared rangefinder 8 is located directly below the centrifugal rotor 5, and the light beam of the infrared rangefinder 8 shines directly below the centrifugal rotor 5.

[0038] Specifically, by shining the light beam of the infrared rangefinder 8 directly below the centrifugal rotor 5, the balance of the centrifugal rotor 5 can be monitored in real time, preventing imbalance of the centrifugal rotor 5 from affecting the centrifugation efficiency or damaging the centrifuge.

[0039] Furthermore, the distance between the magnetic slider 17 and the inner liner 7 is greater than the thickness of the top cover 12.

[0040] Specifically, by making the distance between the magnetic slider 17 and the inner liner 7 greater than the thickness of the top cover 12, the magnetic slider 17 can be locked onto the top cover 12 when it is closed.

[0041] 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 should be included within the protection scope of the present utility model.
