This is typically performed using a thermomixer, which utilizes built-in heating and cooling systems and a high-performance motor to achieve precise temperature control and rapid, uniform mixing.

[0003] When the existing constant temperature mixer is mixing samples at a constant temperature, some samples have a high constant temperature, so when the samples are taken out after the constant temperature mixing, they are easily in contact with the placement tank, causing the operator to be burned by the placement tank, which poses a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to provide a precise mixing device under constant temperature control to solve the problem in the above background technology that when the existing constant temperature mixer is performing constant temperature mixing on samples, due to the high constant temperature of some samples, the samples after constant temperature mixing are easily contacted with the placement tank when being taken out, causing the operator to be burned by the placement tank, which poses a safety hazard.

[0005] In order to solve the above technical problems, the present invention provides a precise mixing device under constant temperature control, comprising:

[0006] A constant temperature mixing assembly, the constant temperature mixing assembly comprising a placement tank;

[0007] The movable component includes a first telescopic spring connected to the top position of the placement slot, a retaining ring connected to the top position of the first telescopic spring, a movable column connected to the four corners inside the placement slot, a fixed plate connected to the top position of the movable column, a sliding groove opened at the outer position of the fixed plate, a slider connected to the inner position of the sliding groove, a support rod connected to the outer end position of the slider, a limit block connected to the inner side position of the lower end of the support rod, and a limit groove opened at the lower end position of the outer side of the placement slot.

[0008] Furthermore, the constant temperature mixing assembly also includes a constant temperature mixer body, a cover connected to the upper end of the constant temperature mixer body, and a control button connected to the outer side of the constant temperature mixer body, and the placement slot is connected to the top end of the constant temperature mixer body.

[0009] Furthermore, the fixing plate is located above the clamping ring, and the sliding groove is opened relative to the sliding block.

[0010] Furthermore, the support rod is located outside the fixing plate and the placement groove, and the support rod is located inside the cover plate.

[0011] Furthermore, the movable column extends upward through the placement slot, and the limiting slot is opened relative to the limiting block.

[0012] Furthermore, it also includes an anti-accidental touch component, which includes a guide rod connected to the outer end of the constant temperature mixer body, a second telescopic spring connected to the inner side of the outer end of the constant temperature mixer body, a sliding rod connected to the outer end of the second telescopic spring, a protective plate connected to the inner side of the sliding rod, and a baffle connected to the bottom end of the sliding rod.

[0013] Furthermore, the second telescopic spring surrounds the outer surface of the guide rod, and the sliding rod is connected to the outer surface of the guide rod.

[0014] Furthermore, the baffle is located outside the protective plate, and the protective plate is located outside the control button.

[0015] Compared with the prior art, the present invention has the following beneficial effects: by setting a movable component, after the sample is placed in the placement groove, the support rod is moved downward, so that the support rod drives the fixing plate to move downward through the slider, and the fixing plate moves downward to drive the sample to move downward, so that the sample can be fixed in the placement groove and is not easy to slide outward; and when the sample needs to be removed, the support rod is moved so that the support rod drives the limiting block to disengage from the limiting groove. Under the elastic force of the first telescopic spring, the sample can be driven by the clamping ring to move upward, so that the sample can maintain a certain distance from the placement groove, thereby preventing the operator from being burned by the placement groove;

[0026] A constant temperature mixing component, the constant temperature mixing component includes a placement tank 12;

[0027] The movable component includes a first telescopic spring 21 connected to the top position of the placement slot 12, a retaining ring 22 connected to the top position of the first telescopic spring 21, a movable column 23 connected to the four corners inside the placement slot 12, a fixed plate 24 connected to the top position of the movable column 23, a slide groove 25 opened at the outer position of the fixed plate 24, a slider 26 connected to the inner position of the slide groove 25, a support rod 27 connected to the outer end position of the slider 26, a limit block 28 connected to the inner side position of the lower end of the support rod 27, and a limit groove 29 opened at the lower end position of the outer side of the placement slot 12.

[0028] The first telescopic spring 21 is used to reset the clamping ring 22, the clamping ring 22 is used to support the upper end of the sample tube, the movable column 23 is used to support the fixed plate 24, the fixed plate 24 is used to limit the upper end of the sample tube, the slide groove 25 is used to guide the movement of the slider 26, the slider 26 is used to support the support rod 27, the support rod 27 is used to support the limit block 28, the limit block 28 is used to limit the support rod 27, and the limit groove 29 is used to limit the limit block 28.

[0029] The constant temperature mixing assembly also includes a constant temperature mixer body 11, a cover 13 connected to the upper end of the constant temperature mixer body 11, and a control button 14 connected to the outer side of the constant temperature mixer body 11, and the placement slot 12 is connected to the top end of the constant temperature mixer body 11.

[0030] The thermostatic mixer body 11 is used to perform constant temperature mixing on the sample, the placement slot 12 is used to place the sample tube, the cover 13 is used to seal the outside of the placement slot 12, and the control button 14 is used to change the parameters of the thermostatic mixer body 11.

[0031] The fixing plate 24 is located above the snap ring 22 , and the sliding groove 25 is opened relative to the sliding block 26 .

[0032] The fixing plate 24 and the clamping ring 22 respectively limit the upper end of the sample tube.

[0033] The support rod 27 is located outside the fixing plate 24 and the placement groove 12 , and the support rod 27 is located inside the cover plate 13 .

[0034] The support rod 27 can slide along the outer side of the fixing plate 24 under the drive of the slider 26, and the fixing plate 24 can drive the support rod 27 to move up and down.

[0035] The movable column 23 extends upward through the placement slot 12 , and the limiting slot 29 is opened relative to the limiting block 28 .

[0036] When the limiting block 28 is located inside the limiting groove 29 , the support rod 27 is fixed by the limiting block 28 , and the support rod 27 drives the fixing plate 24 to remain fixed.

[0037] Working principle: When the sample tube needs to be mixed at a constant temperature, the sample tube is placed inside the placement groove 12, and a downward force is applied to the fixing plate 24 to move the fixing plate 24 downward. The downward movement of the fixing plate 24 drives the slider 26 and the support rod 27 to move downward. When the bottom end of the fixing plate 24 contacts the top end of the sample tube, the fixing plate 24 continues to move, which drives the sample tube and the clamping ring 22 to move downward, and drives the first telescopic spring 21 to be compressed. Then the support rod 27 is moved so that the support rod 27 drives the limit block 28 to move into the limit groove 29. The limit block 28 limits the support rod 27, so that the fixing plate 24 and the clamping ring 22 clamp and fix the upper end of the sample tube. At this time, the constant temperature mixer body 11 is started, and the sample inside the sample tube can be mixed at a constant temperature.

[0038] When the sample tube needs to be removed, a moving force is applied to the support rod 27, so that the support rod 27 drives the limit block 28 to disengage from the limit groove 29. The limit block 28 does not limit the support rod 27. Under the elastic force of the first telescopic spring 21, the clamping ring 22 moves downward, and the clamping ring 22 drives the sample tube and the fixed plate 24 to move downward. Then an upward force is applied to the support rod 27, so that the fixed plate 24 continues to move upward under the drive of the support rod 27 until it is separated from the top of the sample tube. At this time, the sample tube moves to the position above the placement groove 12 under the drive of the first telescopic spring 21 and the clamping ring 22, so that the operator can maintain a safe distance from the placement groove 12 when removing the sample tube.

[0045] When the protection plate 34 is located on the outer surface of the lower end of the guide rod 31 , the baffle 35 supports the protection plate 34 so that the protection plate 34 does not fall off the guide rod 31 .

[0046] Working principle: When the control button 14 needs to be operated, an upward force is applied to the slide bar 33, and the slide bar 33 moves upward, driving the protective plate 34 to move upward, so that the protective plate 34 is removed from the outside of the control button 14 and does not block the control button 14, and the slide bar 33 drives the second telescopic spring 32 to be compressed, and the control button 14 can be operated. When the operation is completed, the force applied to the slide bar 33 is stopped, and under the elastic force of the second telescopic spring 32, the slide bar 33 moves downward to reset, and the downward movement of the slide bar 33 drives the protective plate 34 to move downward to the outside of the control button 14, blocking the control button 14, thereby preventing the control button 14 from being accidentally touched.
