[0029] Example 1

[0030] Reference Figures 1-4 This first embodiment of the present invention proposes a constant temperature mixer for testing medical equipment, including a base mechanism 3, a fixing mechanism 2 installed at the top of the base mechanism 3, the fixing mechanism 2 including a mounting block 202, the mounting block 202 having four sets of mounting slots 203, each set of mounting slots 203 having a placement rack mechanism 4, and the top of each set of mounting slots 203 being threadedly connected to a heat insulation and sound insulation mechanism 1; by opening four sets of mounting slots 203 on the mounting block 202, it is convenient for users to conduct simultaneous experiments on multiple control groups by controlling different variables during mixing, which is beneficial to improving experimental efficiency, and can provide multiple mixing modes and speeds to choose from according to different internal raw materials;

[0031] The placement rack mechanism 4 includes a lower fixed plate 402, a support column 403 is fixedly connected to the top center of the lower fixed plate 402, an upper fixed plate 401 is fixedly connected to the top of the support column 403, and a number of evenly distributed through slots 404 are opened on the upper fixed plate 401; the through slots 404 facilitate the storage of test tubes.

[0032] Each set of through slots 404 is slidably connected to two sets of symmetrical arc-shaped clamping blocks 406. The two sets of arc-shaped clamping blocks 406 are fixedly connected by springs 408. A rubber pad 407 is fixedly connected to the inner wall of the side of the two sets of arc-shaped clamping blocks 406 that are close to each other. By setting the springs 408 to drive the two sets of arc-shaped clamping blocks 406 to move closer to each other, the test tube is fixed. This allows the device to clamp and fix test tubes of various diameters. By setting the rubber pad 407 on the side of the arc-shaped clamping blocks 406 that is close to the test tube, it is beneficial to prevent the arc-shaped clamping blocks 406 from falling off or breaking.

[0033] The lower fixed plate 402 is provided with a number of placement slots 405 corresponding to the through slots 404. The placement frame mechanism 4 is engaged with the eccentric wheel 206. The eccentric wheel 206 is rotatably connected to the mounting slot 203. By rotating the eccentric wheel 206, the placement frame mechanism 4 is driven to rotate, and the raw materials stored inside the placement frame mechanism 4 are mixed.

[0034] A semiconductor cooling heating element 204 is fixedly connected to one side of the inner wall of each set of mounting slots 203, and a temperature sensor 205 is fixedly connected to the other side of the inner wall of each set of mounting slots 203. A control panel 201 is fixedly connected to the front end of the mounting block 202. The temperature sensor 205 can measure the temperature inside the mounting slot 203 and control the semiconductor cooling heating element 204 to heat or cool the inside of the mounting slot 203.

[0035] In this embodiment, by setting sliding arc-shaped clamping blocks 406 inside each set of through slots 404, and by setting springs 408 to drive the two sets of arc-shaped clamping blocks 406 to move closer to each other to fix the test tube, the device can clamp and fix test tubes of various diameters. By setting rubber pads 407 on the side of the arc-shaped clamping blocks 406 near the test tube, it is beneficial to prevent the arc-shaped clamping blocks 406 from falling off or breaking, which helps to improve the stability of the test tube, makes it easier to handle, and is suitable for test tubes of various sizes, thus improving the practicality of the device.

[0036] Example 2

[0037] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0038] The thermal insulation and sound insulation mechanism 1 includes a thermal insulation and sound insulation cover 101, which is threadedly connected to the mounting groove 203. A threaded rod 102 is threadedly connected to the thermal insulation and sound insulation cover 101. One end of the threaded rod 102 passes through the thermal insulation and sound insulation cover 101 and is rotatably connected to a baffle 103. The baffle 103 is slidably connected to the thermal insulation and sound insulation cover 101. A replaceable sponge pad is fixedly connected to the bottom end of the baffle 103. By rotating the threaded rod 102, the baffle 103 is driven to slide along the inner wall of the thermal insulation and sound insulation cover 101, causing the baffle 103 to approach the test tube and the stopper, thus limiting their movement. This helps to improve the stability of the test tube and prevents the stopper from falling off during mixing, causing reagent spillage and material waste. The sponge pad helps to prevent the test tube from breaking due to hard contact with the baffle 103.

[0039] The base mechanism 3 includes a housing 301, which is snapped onto the bottom end of the mounting block 202. A microcontroller 302 is fixedly connected to the housing 301. The microcontroller 302 is electrically connected to an electric motor 303, a temperature sensor 205, a semiconductor cooling and heating element 204, and a control panel 201. The microcontroller 302 receives instructions from the experimenter and controls the temperature and speed of mixing inside each mounting slot 203.

[0040] Four sets of electric motors 303 are fixedly connected to the outer shell 301. The output end of each set of electric motors 303 passes through the mounting block 202 and is fixedly connected to the eccentric wheel 206. The reagent is mixed by driving the electric motors 303 to rotate the eccentric wheel 206.

[0041] In this embodiment, the single-chip microcomputer 302 is electrically connected to the electric motor 303, temperature sensor 205, semiconductor cooling and heating element 204, and control panel 201. The single-chip microcomputer 302 receives instructions from the experimenter and controls the temperature and speed of mixing inside each mounting slot 203. By rotating the threaded rod 102, the baffle 103 is driven to slide along the inner wall of the heat insulation and soundproof cover 101, which brings the baffle 103 close to the test tube and the stopper, limiting their position. This helps to improve the stability of the test tube and prevents the stopper from falling off during the mixing process, causing reagent spillage and material waste.
