[0045] The technical scheme of the utility model is further illustrated below in combination with the drawings and through specific embodiments.
[0046] As shown in the figure, Figures 1 to 2 The vortex mixing device provided by the embodiment includes a fixed cylinder 1, a driving structure 2 and a fixing structure 3. The fixed cylinder 1 surrounds a fixed chamber 10. The driving structure 2 includes a driving mechanism 21, a driving gear 22 and a plurality of driven gears 23. The driving mechanism 21 is arranged on the bottom wall of the fixed chamber 10. The driving gear 22 is arranged on the output end of the driving mechanism 21. The plurality of driven gears 23 are distributed on the outer side of the driving gear 22 in a circumferential direction. Each driven gear 23 is rotatably arranged on the bottom wall of the fixed chamber 10 and engages with the driving gear 22. Figure 3 The fixing structure 3 includes a fixing plate 31, a plurality of annular air bags 32 and a plurality of limiting seats 33. The fixing plate 31 is arranged in the fixed chamber 10. In combination with , the fixing plate 31 is provided with a plurality of fixing holes 310 in a circumferential direction. Each fixing hole 310 is provided with an annular air bag 32. The annular air bag 32 has an inflated state abutting against the outer wall of the test tube 100 and a natural state not abutting against the outer wall of the test tube 100. The plurality of limiting seats 33 are arranged on the plurality of driven gears 23 in a one-to-one correspondence. Each limiting seat 33 is provided with a limiting cavity 330. The test tube 100 passes through the annular air bag 32 and is arranged in the limiting cavity 330 to limit the test tube 100. In use, a plurality of test tubes 100 containing samples to be tested and reaction reagents pass through the corresponding annular air bags 32 and are arranged in the corresponding limiting cavities 330. Then, the annular air bags 32 are inflated. The annular air bags 32 are adjusted to the inflated state. The test tubes 100 are stably inserted into the fixing holes 310. The limiting of the test tubes 100 does not hinder the rotation of the test tubes 100 relative to the annular air bags 32. Then, the driving mechanism 21 is started to drive the driving gear 22 to rotate around its axis, simultaneously driving the plurality of driven gears 23 to rotate, and further driving the plurality of test tubes 100 to rotate, so as to realize the sufficient mixing of the samples and the reaction reagents, replace the manual shaking of the test tubes 100, ensure the uniformity of the mixing of the samples and the reaction reagents, and greatly improve the mixing efficiency.
[0047] Illustratively, the driving mechanism 21 is a motor commonly used in the art. The annular air bag 32 is an existing device disclosed in the prior art.
[0048] Figure 2 Optionally, as shown in the figure, The driving structure 2 further includes a plurality of rotating rods 24 connected to the plurality of driven gears 23 in a one-to-one correspondence. Each rotating rod 24 is rotatably arranged on the bottom wall of the fixed chamber 10. The rotation stability of the driven gears 23 is improved, and the stability of the test tubes 100 is also improved.
[0049] Figure 4As shown, an inflation channel 311 is provided inside the fixing plate 31, and each annular airbag 32 is connected to the inflation channel 311; combined with Figure 2 An inflation mechanism 312 is provided on the outer wall of the fixed cylinder 1. A gas supply pipe 313 connects the output end of the inflation mechanism 312 to the inflation channel 311. The gas output from the inflation mechanism 312 enters the inflation channel 311 through the gas supply pipe 313, and then enters multiple annular air bags 32 respectively, to ensure that the multiple annular air bags 32 can be smoothly switched to the inflation state and to ensure the stability of the test tube 100 contact.
[0050] For example, refer to Figure 5 In this embodiment, the inflation channel 311 is annular; the inflation mechanism 312 is an air pump commonly used in the art.
[0051] Specifically, each annular airbag 32 is provided with an exhaust port, and a sealing plug is provided at the exhaust port. Before and during accurate inflation of the annular airbag 32, the sealing plug remains in place at the exhaust port. When it is necessary to remove the test tube 100 and switch the annular airbag 32 to its natural state, the sealing plug is opened, allowing the gas inside the annular airbag 32 to escape through the exhaust port, thus releasing the pressure on the test tube 100. Alternatively, the exhaust port on the annular airbag 32 can be omitted, and the inflation mechanism 312 can be replaced with a suction mechanism. The suction mechanism can be a commonly used vacuum pump in the art, which extracts the gas from the annular airbag 32 to switch it to its natural state.
[0052] Furthermore, referring to Figure 2 An adjusting valve 3130 is installed on the gas supply pipe 313. The adjusting valve 3130 can precisely adjust the gas flow rate, realize on-demand control of the inflation speed, avoid the sudden increase in internal pressure of the annular airbag 32 due to excessive inflation and rupture, and extend the service life of the annular airbag 32. At the same time, by controlling the inflation speed, the softness and hardness of the annular airbag 32 under inflation can also be adjusted to meet personalized needs.
[0053] Specifically, the regulating valve 3130 is also an existing device that has been disclosed in the prior art. Its specific structure and principle are the same as those in the prior art and will not be described in detail here.
[0054] Optionally, such as Figure 2 As shown, the vortex mixing device also includes a liquid addition structure 4, which includes a top plate 41 and multiple liquid addition droppers 42. The top plate 41 is spaced apart above the fixed cylinder 1, and the multiple liquid addition droppers 42 are spaced apart circumferentially on the side of the top plate 41 facing the fixed cylinder 1. Each test tube 100 is provided with one liquid addition dropper 42. This arrangement allows for the addition of samples or reaction reagents to the test tube 100 during rotation, which is beneficial for improving detection efficiency. At the same time, it also improves the uniformity of the mixing of samples and reaction reagents.
[0055] Further, with continued reference to Figure 2 The liquid adding structure 4 further comprises a plurality of liquid storage barrels 43, which are arranged on the top plate 41 away from the fixed cylinder 1, and a plurality of liquid adding droppers 42 are correspondingly connected to the plurality of liquid storage barrels 43. The reaction reagent or sample to be added can be stored in the liquid storage barrel 43 in advance for subsequent addition and use, thereby improving the detection efficiency.
[0056] Specifically, a plurality of channels are formed on the top plate 41, and each channel is connected between the corresponding liquid adding dropper 42 and the liquid storage barrel 43.
[0057] Further, as shown in Figure 2 Each liquid adding dropper 42 is provided with a control valve 420, which can adjust the flow rate of the liquid adding dropper 42 to realize accurate addition of the reaction reagent and sample.
[0058] Specifically, the control valve 420 is also an existing device disclosed in the prior art, and its specific structure and principle are referred to the prior art, which will not be described here.
[0059] Optionally, as shown in Figure 2 The liquid adding structure 4 further comprises a telescopic mechanism 44 arranged outside the fixed cylinder 1, and the top plate 41 is arranged at the output end of the telescopic mechanism 44. Under the drive of the telescopic mechanism 44, the top plate 41 can move in the vertical direction, approaching or moving away from the fixed cylinder 1. When it is necessary to add the sample or reaction reagent into the test tube 100 by the liquid adding dropper 42, the top plate 41 can be driven to move towards the fixed cylinder 1, so as to reduce the distance between the bottom end of the liquid adding dropper 42 and the upper end inlet of the test tube 100, thereby ensuring that the added sample or reaction reagent can smoothly enter the test tube 100. After the addition is completed, the top plate 41 is driven to move away from the fixed cylinder 1, so as to increase the distance between the liquid adding dropper 42 and the test tube 100, thereby preventing the test tube 100 from interfering with the liquid adding dropper 42 during the subsequent rotation of the test tube 100.
[0060] For example, in the embodiment, the telescopic mechanism 44 is a hydraulic rod commonly used in the art, which has the advantages of compact structure, small size and light weight.
[0061] Further, as shown in Figure 1 and Figure 2 The vortex mixing device further comprises a base plate 5, and the fixed cylinder 1 and the telescopic mechanism 44 are fixedly arranged on the base plate 5, so as to improve the integrity of the device.
[0062] Optionally, with reference to Figure 2The vortex mixing device also includes a heating structure 6, which is disposed on the side wall of the fixed chamber 10 and located between the fixed plate 31 and the bottom wall of the fixed chamber 10. When the sample to be tested and the reaction reagent have temperature requirements, or when there are temperature requirements for the sample, the heating structure 6 can be used to heat it to ensure that the temperature of the space between the fixed plate 31 and the fixed chamber 10 meets the detection requirements. Specifically, the heating structure 6 is also a prior art device disclosed in the art, and its specific structure and principle will not be described in detail here.
[0063] Specifically, such as Figure 6 As shown, in this embodiment, the extending direction of the limiting cavity 330 is inclined, combined with... Figure 2 The central axis of the annular airbag 32 is collinear with the axis of the corresponding driven gear 23. That is, the extending direction of the limiting cavity 330 on the limiting seat 33 is not vertical, but rather at an angle to the vertical direction. With this configuration, when the bottom end of the test tube 100 is placed inside the limiting cavity 330 and the top end is abutted by the annular airbag 32, the test tube 100 is tilted. During the rotation of the test tube 100 driven by the driven gear 23, the sample and reaction reagents inside the test tube 100 are subjected to centrifugal force, thereby increasing the mixing rate and uniformity of the two.
[0064] Alternatively, in other embodiments, the limiting cavity 330 may also extend vertically. When the bottom end of the test tube 100 is placed in the limiting cavity 330, the test tube 100 is perpendicular to the upper end face of the driven gear 23, which can also achieve full mixing of the sample and the reaction reagent in the test tube 100.
[0065] Optionally, the vortex mixing device also includes a control panel 7. For example... Figure 1 As shown, the control panel 7 is located on the outer wall of the fixed cylinder 1. The drive mechanism 21, the inflation mechanism 312, and the heating structure 6 are all connected to the control panel 7. The control panel 7 can control the start and stop of the drive mechanism 21 and its speed, the start and stop of the inflation mechanism 312, and the start and stop of the heating mechanism and its temperature setting. The regulating valve 3130 and each control valve 420 are also connected to the control panel 7 to facilitate quick adjustment of the inflation flow rate and liquid addition flow rate, making it more convenient and improving detection efficiency.
[0066] Specifically, the control panel 7 is a controller commonly used in this field. The controller has relevant control programs burned on it. The specific structure and principle of the controller refer to the existing technology, and the relevant control programs also refer to the existing technology, which will not be described in detail here.
[0067] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
