Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to an air-cooled temperature-controlled medical centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions. It can also be used to remove liquid from wet solids. Special ultra-speed tubular separators can also separate gas mixtures of different densities. Some sedimentation centrifuges can also classify solid particles by density or size, taking advantage of the fact that solid particles of different densities or particle sizes have different sedimentation rates in liquids.

[0003] According to the patent document with the authorization announcement number CN218945341U and the name "A medical centrifuge with air cooling and temperature control", the new model includes a shell, a cover plate is hinged on the upper end of the shell, a motor and an exhaust fan are installed on the inner bottom wall of the shell, a baffle is fixedly connected to the inner side wall of the shell, the output shaft of the motor is fixedly connected to the transmission shaft through a coupling, the upper end of the transmission shaft passes through the baffle and is provided with a rotor, an air inlet is provided on the bottom wall of the shell and located at the exhaust fan, an air duct is fixedly connected to the baffle, a branch pipe is fixedly connected to the side wall of the air duct, and a plurality of air outlets are provided on the cover plate. The effect is that the exhaust fan draws cold air from the outside through the air inlet and sends it into the air duct, the cold air in the air duct is blown out through the branch pipe, the cold air passes between the rotor and the shell and takes away the heat of the rotor, and is finally discharged through the air outlet, and the rotating rotor can also ensure uniform heat dissipation, thereby achieving a better heat dissipation effect.

[0029] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0030] Example 1

[0031] like Figure 1and 3 As shown in Figures 4 and 5, the present invention proposes an air-cooled and temperature-controlled medical centrifuge, comprising: a housing 1; a test tube centrifuge assembly 2, located in the housing 1; a guide assembly 3, located in the housing 1, for guiding cold air and cooperating with the air-cooled temperature control component below to achieve air-cooled temperature control of the test tube centrifuge assembly 2; a cover plate 4, located on the housing 1, for cooperating with the housing 1 to close or open, an exhaust port 5 located on the cover plate 4, for heat discharge; and a dustproof assembly 6, located below the cover plate 4, for dustproofing and cooperating with the exhaust port 5 to discharge heat.

[0032] To further illustrate, guide assembly 3 includes a guide hood 301 located within housing 1. This hood surrounds rotor 205 from the outside, leaving a temperature-controlled cavity between the hood and rotor 205 for cooling air to circulate. A central hole 302 is provided at the bottom of guide hood 301 for the tray shaft 203 to pass through and connect to the rotating shaft 202. Guide hood 301 is provided within the housing to guide the cooling air, thereby improving cooling efficiency.

[0033] To further illustrate, the temperature control unit includes an air duct 303 located on the guide cover 301. An exhaust fan 304 is provided at the air inlet end of the air duct 303, and the air outlet end is connected to the temperature control chamber. The exhaust fan 304 is provided with an air inlet 305, which is used to cooperate with the exhaust fan 304 to achieve air-cooling temperature control. The exhaust fan 304 delivers cold air into the temperature control chamber through the air outlet end, and then cooperates with the air inlet 305. The lower end of the air inlet 305 extends to the outer wall of the housing 1, cooperating to deliver cold air into the temperature control chamber, further improving the efficiency of air-cooling temperature control.

[0034] Further explanation: Dustproof assembly 6 includes a dust cover 601 located below cover plate 4. Dust cover 601 is provided with a vent 602 for heat dissipation; activated carbon 603 is provided above dust cover 601 to cooperate with dust cover 601 to enhance dustproofing. Dust cover 601 is connected to the top of housing 1 via cover plate 4. Cover plate 4 is opened and dustproof assembly 6 is opened for use, making it convenient to remove test tubes or place them for centrifugation. The convenient connection and use between dustproof assembly 6 and cover plate 4 prevents dust and other objects from entering housing 1, thereby preventing the use of test tube centrifugation assembly 2, facilitating the placement of test tubes in test tube slot 207, and preventing blockage of the air cooling control port, thereby improving the use of air cooling temperature control.

[0035] To further illustrate, mounting blocks 604 are provided on either side of the dust cover 601. These are bolted to the underside of the cover plate 4 and serve to align the dust cover 601 with the exhaust port 5. By threading the lower ends of the bolts through the cover plate 4 and the underside of the mounting blocks 604, mounting blocks 604 are secured to the underside of the cover plate 4. This allows the dust cover 601 to be mounted on the underside of the cover plate 4, facilitating heat dissipation.

[0036] Example 2

[0037] like Figure 2 and 3 As shown, the present invention proposes an air-cooled temperature-controlled medical centrifuge. Based on the above embodiment, this embodiment also details the specific components and the matching method.

[0038] To further illustrate, the test tube centrifuge assembly 2 includes a motor 201 located within the housing 1. A rotating shaft 202 is disposed above the motor 201. A tray shaft 203 is disposed above the rotating shaft 202. Tray shaft 203 extends through a tray hole 204 and has a centrifugal element disposed on its top. Motor 201 drives rotating shaft 202, which rotates the tray shaft 203. The centrifugal element is disposed on the tray shaft 203, causing the centrifugal element to rotate with it.

[0039] Further explanation: The centrifugal element includes a rotor 205, which is connected to the tray shaft 203 through the tray hole 204 in the center. The rotor 205 is hollow, and the sidewall is provided with an air outlet 206 that communicates with its internal cavity. The rotor 205 is provided with a test tube slot 207 that extends into the cavity in a sealed manner, and the upper end opening of the test tube slot 207 is located above the rotor 205 and outside, allowing the test tube to be placed. Due to the hollow structure of the rotor 205, the air outlet 206 is provided on the sidewall to flow cold air into it. Subsequently, the test tube slot 207 is extended from the rotor 205. The connection point of the test tube slot 207 and the air outlet 206 intersects, so that both are connected to the rotor 205, achieving air cooling and temperature control of the test tube slot 207. The test tube slot 207 is used to place test tubes, achieving the purpose of test tube centrifugation.

[0040] The working principle of the present invention is as follows: First, the cover 4 is opened, and then the test tubes are placed in the corresponding test tube slots 207 to centrifuge the test tubes. The test tube slots 207 are extended and mounted on the rotor 205. The outer side of the rotor 205 is provided with an air outlet 206 for air cooling and temperature control. A guide cover 301 is installed in the housing 1. The bottom end of the guide cover 301 is provided with a center hole 302. The center hole 302 is connected to the rotating shaft 202 and the tray shaft 203. The rotating shaft 202 is connected to the motor 201. When the motor 201 is turned on, the rotating shaft 202 rotates. The rotating shaft 202 rotates, and the tray shaft 203 rotates. The tray shaft 203 is connected to the rotor 205 through the tray hole 204. The rotor 205 rotates to centrifuge the test tubes. The rotor 205 is wrapped by using a guide cover 301, and a temperature control cavity for cold air circulation is left in between. At the same time, the guide cover 301 is connected to the exhaust fan 304 through the air duct 303. The exhaust fan 304 flows the cold air into the air duct 303 through the air inlet 305. The cold air flows into the temperature control cavity through the air duct 303 and flows into the rotor 205 through the air outlet 206, so as to achieve air cooling and temperature control of the test tube centrifuge assembly 2. The air outlet 206 is connected to the rotor 205, and the hot air is discharged from the air outlet 206 at the same time. The hot air is discharged through the exhaust port 5 on the cover plate 4. The mounting block 604 and the cover plate 4 are connected by using bolts. The mounting block 604 is provided with a dust cover 601. The dust cover 601 is provided with a vent 602. The vent 602 cooperates to discharge heat. At the same time, activated carbon 603 is placed on the dust cover 601 as needed. The dust cover 601 and activated carbon 603 are used to block and filter dust and other objects. The dust cover 601 can be disassembled by bolts to clean the dust objects that block the filtration. At the same time, new activated carbon 603 can be replaced for use, which is convenient for increasing the use of air-cooled temperature-controlled medical centrifuges.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
