Description

Technical Field

[0001] The utility model relates to the technical field of homogenizers, in particular to a homogenizer for processing biological samples. Background Art

[0002] Homogenizers are mainly used for tissue dispersion in the field of biotechnology, sample preparation in the medical field, enzyme treatment in the food industry, detection of pesticide residues and veterinary drug residues in food, as well as in the pharmaceutical industry, cosmetics industry, paint industry and petrochemical industry. The principle of the homogenizer for biological sample processing is to mix the experimental sample and solution or solvent evenly to achieve the standard solution required by the experiment.

[0003] However, when using the current homogenizer, the reaction container is directly placed on the operating table. During the homogenization and mixing process, the reaction container is easily displaced or shaken, causing the internal solution to splash out. In addition, the stirring blades of the general homogenizer are fixed in position and cannot stir solutions of different depths, resulting in poor mixing effect. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a homogenizer for processing biological samples includes a base 1, a clamping mechanism 4 is provided in the middle of the base 1, a lifting mechanism 2 is provided on the upper rear side of the base 1, and a stirring mechanism 3 is provided on the front side of the output end of the base 1.

[0022] In this embodiment, the clamping mechanism 4 includes a fixed seat 401, a connecting rod 402, a spring 403, multiple clamping rods 404, a support seat 405, multiple slide grooves 407 and a traction seat 408. The lower end of the connecting rod 402 is fixedly connected to the middle of the traction seat 408, and the corners of the traction seat 408 are slidably connected to the inside of the slide groove 407. The slide groove 407 is opened at the lower part of the clamping rod 404. The middle parts of multiple clamping rods 404 are rotatably connected to the lower part of the fixed seat 401. The outer periphery of the connecting rod 402 is slidably connected to the middle of the fixed seat 401. The middle part of the support seat 405 is fixedly connected to the upper end of the connecting rod 402. The spring 403 is sleeved on the outer periphery of the connecting rod 402. The spring 403 is arranged between the fixed seat 401 and the support seat 405. The upper part of the fixed seat 401 is fixedly connected to the inner top wall of the base 1. The upper end of the clamping rod 404 is provided with a roller 406. The outer periphery of the roller 406 is wrapped with rubber. A plurality of suction cups are provided at the lower part of the base 1.

[0023] Specifically, when the reaction container is placed on the support seat 405, gravity will cause the support seat 405 to overcome the elastic force of the spring 403, so that the connecting rod 402 drives the traction seat 408 to move downward. Since the middle part of the clamping rod 404 is rotated and connected to the lower part of the fixed seat 401, the corners of the traction seat 408 slide inside the slide groove 407, thereby causing the clamping rod 404 to deflect, and then clamped to the outer periphery of the reaction container through the roller 406 to prevent the reaction container from moving or shaking during stirring.

[0024] In this embodiment, the lifting mechanism 2 includes a servo motor 201, a limiting rod 202, a threaded rod 203, a connecting plate 204 and a moving seat 205. The lower end of the limiting rod 202 is fixedly connected to the upper part of the base 1, the lower end of the threaded rod 203 is rotatably connected to the upper part of the base 1, one end of the connecting plate 204 is fixedly connected to the upper end of the limiting rod 202, the upper end of the threaded rod 203 is rotatably connected to the other end of the connecting plate 204, one end of the moving seat 205 is slidably connected to the outer periphery of the limiting rod 202, the middle part of the moving seat 205 is threadedly connected to the periphery of the threaded rod 203, and the stirring mechanism 3 is installed at the other end of the moving seat 205. The servo motor 201 is installed on the inner top wall of the base 1. The upper end of the servo motor 201 passes through the wall shell of the base 1 and is fixedly connected to the lower end of the threaded rod 203. The stirring mechanism 3 includes a reduction motor 301, a stirring rod 302 and a stirring blade 303. The upper end of the stirring rod 302 is rotatably connected to the lower part of the movable seat 205. The reduction motor 301 is installed on the upper part of the movable seat 205. The lower driving end of the reduction motor 301 passes through the movable seat 205 and is fixedly connected to the upper end of the stirring rod 302. The middle part of the stirring blade 303 is fixedly connected to the lower part of the stirring rod 302. The upper periphery of the stirring rod 302 is slidably connected with a splash-proof cover 304.

[0025] Specifically, the reduction motor 301 is driven so that the stirring rod 302 drives the stirring blade 303 to rotate, thereby stirring the solution. The movable seat 205 is limited by the limiting rod 202, so that when the servo motor 201 drives the threaded rod 203 to rotate, the movable seat 205 can drive the stirring mechanism 3 to move, thereby stirring solutions of different depths and improving the mixing effect.

[0026] Working principle:

[0027] When the reaction container is placed on the support seat 405, gravity will cause the support seat 405 to overcome the elastic force of the spring 403, so that the connecting rod 402 drives the traction seat 408 to move downward. Since the middle part of the clamping rod 404 is rotated and connected to the lower part of the fixed seat 401, the corners of the traction seat 408 slide inside the slide groove 407, thereby causing the clamping rod 404 to deflect, and then clamped to the outer periphery of the reaction container by the roller 406 to prevent the reaction container from moving or shaking during stirring. The reduction motor 301 is driven to make the stirring rod 302 drive the stirring blade 303 to rotate, thereby stirring the solution. The movable seat 205 is limited by the limit rod 202, so that when the servo motor 201 drives the threaded rod 203 to rotate, the movable seat 205 can drive the stirring mechanism 3 to move, thereby stirring solutions of different depths and improving the mixing effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
