[0002] In the chemical and biological fields, oscillating test tubes is a common method for mixing liquids or solids.

[0003] Existing test tube oscillation methods improve and use different oscillation methods to increase the mixing degree of liquids or solids in test tubes, which can effectively improve the mixing degree of liquids. However, these methods only use fixed oscillation steps and do not dynamically adjust the oscillation steps for liquids with different viscosities, and can only produce good mixing effects on liquids with a small range of viscosities. Summary of the Invention

[0004] The embodiments of this application provide a method and device for test tube oscillation, which can solve the problem that existing test tube oscillation methods do not dynamically adjust the oscillation steps for liquids with different viscosities, resulting in good mixing effects only on liquids with a small range of viscosities.

[0005] In a first aspect, the embodiments of this application provide a method for test tube oscillation, which is applied to a test tube oscillation device. The method includes:

[0006] Detect the first mass of the liquid in the test tube;

[0007] The test tube oscillation device starts in a first oscillation mode and detects first force feedback information. Herein, the first oscillation mode refers to the default oscillation mode used by the test tube oscillation device for testing. The first oscillation mode includes a first oscillation frequency and a first oscillation amplitude. The first force feedback information refers to the information related to the magnitude and time of the force between the test tube and the test tube slot during the test tube oscillation process of the test tube oscillation device in the first oscillation mode;

[0008] Obtain a first impact ratio based on the first force feedback information and the first mass. Herein, the first impact ratio refers to the ratio of the maximum impact force of the liquid on the test tube wall to the liquid mass during the test tube oscillation process of the test tube oscillation device in the first oscillation mode;

[0009] Obtain a first oscillation acceleration based on the first oscillation frequency and the first oscillation amplitude.

[0012] A method for oscillating a test tube provided by the present application. First, the first mass of the liquid in the test tube is detected. The present application determines whether the oscillation mode of the test tube oscillating device is appropriate by detecting the force of the liquid in the test tube impacting the test tube, and the mass of the liquid directly affects the force of the liquid in the test tube impacting the test tube. Therefore, detecting the first mass of the liquid before the test tube oscillating device oscillates in this step can improve the accuracy of the measured first mass. Secondly, the test tube oscillating device is started in the first oscillation mode, and the first force feedback information is detected. In this step, after starting the test tube oscillating device in the default first oscillation mode, the force feedback of the liquid on the test tube is detected. The first force feedback information is used to reflect the oscillation state of the liquid. Subsequently, a first impact ratio is obtained according to the first force feedback information and the first mass. In this step, the first impact ratio is obtained. The first impact ratio is a scalar, which can not only represent the magnitude of the impact force of the liquid on the test tube, but also does not need to consider the mass of the liquid. Then, a first oscillation acceleration is obtained according to the first oscillation frequency and the first oscillation amplitude. In this step, the first oscillation acceleration is obtained. The first oscillation acceleration is the acceleration of the liquid during the oscillation process under ideal conditions and can be used as a detection threshold for judging the oscillation state of the liquid. Finally, the oscillation mode of the test tube oscillating device is adjusted according to the first impact ratio and the first oscillation acceleration. In this step, the oscillation state of the liquid in the test tube can be judged according to the first oscillation acceleration and the first impact ratio, and then the oscillation mode of the test tube oscillating device is adjusted according to the oscillation state of the liquid. In the method provided by the present application, the test tube oscillating device first oscillates the test tube in the default first oscillation mode, detects the force feedback information between the test tube and the test tube slot, analyzes the force feedback information to judge whether the liquid in the test tube oscillates synchronously (synchronous oscillation means resonance with the test tube oscillating device), then adjusts the oscillation mode of the test tube oscillating device according to the oscillation result of the liquid, and can cycle through all the steps of obtaining the impact ratio and the oscillation acceleration and cycling to adjust the oscillation mode, realizing dynamic adjustment of the oscillation mode of the test tube oscillating device, which can solve the problem that the existing test tube oscillation method does not dynamically adjust the oscillation steps for liquids with different viscosities, resulting in a good mixing effect only for liquids with a viscosity in a small range.

[0034] In the related art, different oscillation methods are often improved and used to improve the mixing degree of liquids or solids in test tubes. For example, using multi-dimensional oscillation methods etc. can effectively improve the mixing degree of liquids. However, these methods only use fixed oscillation steps, neither considering the different viscosities of different liquids nor the problem of whether the liquids oscillate synchronously (synchronous oscillation is similar to resonance, which is called synchronous oscillation when the oscillation frequency of the liquid is equal to the oscillation frequency of the oscillation device), and not dynamically adjusting the oscillation steps for liquids with different viscosities, and can only produce better mixing effects on liquids with viscosities in a small range.

[0035] To solve the above problems, an embodiment of the present application provides a method for test tube oscillation. In this method, first, the first mass of the liquid in the test tube is detected. In the present application, the oscillation mode of the test tube oscillation device is judged by detecting the force of the liquid in the test tube impacting the test tube, and the mass of the liquid directly affects the force of the liquid in the test tube impacting the test tube. Therefore, detecting the first mass of the liquid before the test tube oscillation device oscillates in this step can improve the accuracy of the measured first mass. Secondly, the test tube oscillation device is started in the first oscillation mode, and the first force feedback information is detected. In this step, after starting the test tube oscillation device in the default first oscillation mode, the force feedback of the liquid on the test tube is detected, and the first force feedback information is used to reflect the oscillation state of the liquid. Subsequently, a first impact ratio is obtained according to the first force feedback information and the first mass. In this step, the first impact ratio is obtained. The first impact ratio is a scalar, which can not only represent the magnitude of the impact force of the liquid on the test tube, but also does not need to consider the mass of the liquid. Then, according to the first oscillation frequency and the first oscillation amplitude, a first oscillation acceleration is obtained. In this step, the first oscillation acceleration is obtained. The first oscillation acceleration is the acceleration of the liquid in the oscillation process under ideal conditions and can be used as a detection threshold for judging the oscillation state of the liquid. Finally, according to the first impact ratio and the first oscillation acceleration, the oscillation mode of the test tube oscillation device is adjusted. In this step, the oscillation state of the liquid in the test tube can be judged according to the first oscillation acceleration and the first impact ratio, and then the oscillation mode of the test tube oscillation device is adjusted according to the oscillation state of the liquid. In the method provided by the present application, the test tube oscillation device first oscillates the test tube in the default first oscillation mode, detects the force feedback information between the test tube and the test tube slot, analyzes the force feedback information to judge whether the liquid in the test tube oscillates synchronously (synchronous oscillation means resonance with the test tube oscillation device), then adjusts the oscillation mode of the test tube oscillation device according to the oscillation result of the liquid, and can cycle through all the steps of obtaining the impact ratio and the oscillation acceleration and cycling to adjust the oscillation mode, realizing dynamic adjustment of the oscillation mode of the test tube oscillation device, and can solve the problem that the existing test tube oscillation method does not dynamically adjust the oscillation steps for liquids with different viscosities, resulting in only a good mixing effect for liquids with a viscosity in a small range.

[0036] The method for test tube oscillation provided by the embodiment of the present application can be applied to a test tube oscillation device. At this time, the test tube oscillation device is the execution subject of the method for test tube oscillation provided by the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the test tube oscillation device.

[0037] For example, a test tube oscillation device may include a detection device, an oscillation device, and a control device communicatively connected to the detection device and the oscillation device. The detection device may be a piezoelectric sensor located in the test tube slot of the oscillation device. When the test tube is inserted into the test tube slot of the oscillation device, the test tube and the test tube slot sandwich and closely fit the piezoelectric sensor, and the piezoelectric sensor can detect the force between the test tube and the test tube slot. The oscillation device may be an eccentric wheel test tube oscillation device with variable frequency and variable torque. The frequency conversion function belongs to the prior art, and the torque conversion function can be achieved by using an eccentric wheel with a variable radius of electromagnetic locking type. The control device can control the detection device to detect the first mass, and can also control the detection device to detect the first force feedback information. The control device can control the oscillation device to perform test tube oscillation at different oscillation frequencies and oscillation amplitudes.

[0038] The control device may be a single-chip microcomputer, a mobile phone, a tablet computer, a laptop computer, a desktop computer, a computer, and so on.

[0039] To better understand the method for test tube oscillation provided in the embodiments of the present application, the following provides an exemplary introduction to the specific implementation process of the method for test tube oscillation provided in the embodiments of the present application.

[0040] Figure 1 The schematic flowchart of the method for test tube oscillation provided in the embodiments of the present application is shown. The method for test tube oscillation includes:

[0041] S100, detecting the first mass of the liquid in the test tube.

[0042] It can be understood that the gravity of the test tube and the liquid in the test tube can be detected by a piezoelectric sensor, and then divided by the acceleration of gravity to obtain the mass of the test tube and the liquid in the test tube. A test tube with a fixed specification can be used to obtain the mass of the fixed test tube. Then the first mass is equal to the mass of the test tube and the liquid in the test tube minus the mass of the test tube.

[0043] With such a setting, the first mass can be detected quickly and stably.

[0044] S200, the test tube oscillation device starts in the first oscillation mode and detects the first force feedback information. Wherein, the first oscillation mode refers to the default oscillation mode used by the test tube oscillation device for testing. The first oscillation mode includes the first oscillation frequency and the first oscillation amplitude. The first force feedback information refers to the information related to the magnitude and time of the force between the test tube and the test tube slot during the test tube oscillation process of the test tube oscillation device in the first oscillation mode.

[0045] It can be understood that first, the test tube oscillation device oscillates the test tube in the default oscillation mode. When the oscillation frequency of the test tube oscillation device reaches the first oscillation frequency and the oscillation amplitude reaches the first oscillation amplitude, it means that the test tube oscillation device has achieved stable oscillation. Subsequently, a piezoelectric sensor can be placed between the test tube and the test tube slot to detect the first force feedback information. The piezoelectric sensor can be one, or multiple piezoelectric sensors can be evenly and symmetrically placed. The force-time two-dimensional information detected by the piezoelectric sensor is the first force feedback information.

[0046] With such a setting, detecting the first force feedback information after the test tube oscillation device has achieved stable oscillation can improve the quality of the measured first force feedback information, and the first force feedback information can reflect whether the liquid oscillates synchronously.

[0047] S300. Obtain a first impact ratio based on the first force feedback information and the first mass. Here, the first impact ratio refers to the ratio of the maximum impact force of the liquid on the test tube wall to the mass of the liquid during the oscillation of the test tube by the test tube oscillation device in the first oscillation mode.

[0048] It can be understood that during the oscillation of the test tube, the shear force between the liquids causes the liquids to disperse and mix, and the shear force mainly comes from the collision between the liquid and the test tube wall. This means that under the condition of the same test tube and liquid, the greater the impact force between the liquid and the test tube wall, the easier it is for the liquid in the test tube to mix, and this result conforms to common sense. The impact force between the liquid and the test tube wall is also directly proportional to the mass of the liquid. If the influence of the liquid mass is not excluded, it will cause the test tube oscillation device to adopt different oscillation modes due to different liquid masses when oscillating the same kind of liquid, deviating from the purpose of this application to adjust different oscillation modes according to liquids of different viscosities. Therefore, the magnitude of the representative impact force in the first force feedback information is divided by the liquid mass to obtain the first impact ratio, and the first impact ratio can represent the intensity of the oscillation of the liquid in the test tube. The magnitude of the representative impact force in the first force feedback information can be the peak value of the force during one oscillation period.

[0049] With such a setting, the influence of the liquid mass can be excluded, which is beneficial for the test tube oscillation device to adjust different oscillation modes according to liquids of different viscosities.

[0050] In a possible implementation manner, in step S300, obtaining the first impact ratio based on the first force feedback information and the first mass includes:

[0051] S310. Obtain a target acting force from the first force feedback information. Here, the target acting force refers to the impact force of the liquid on the test tube during the current oscillation period in the first force feedback information.

[0052] It can be understood that within one oscillation period, if the liquid and the test tube oscillation device oscillate synchronously, then ideally there will be exactly one obvious peak in the first force feedback information (at this time, most of the liquid just impacts the test tube wall where the piezoelectric sensor is located), and the target acting force is the peak acting force. At this time, the target acting force is the most representative impact force in the current oscillation period of the first force feedback information.

[0053] With such a setting, the magnitude of the peak acting force can effectively represent the magnitude of the impact force of the liquid in the test tube within one oscillation period.

[0054] In a possible implementation manner, in step S310, obtaining the target acting force from the first force feedback information includes:

[0055] S311, obtaining the current oscillation period.

[0056] It can be understood that the oscillation speed of the test tube oscillation device sometimes changes, so the oscillation periods at different times are also different. The instantaneous oscillation frequency of the test tube oscillation device can be monitored at all times, and 1 / instantaneous oscillation frequency = instantaneous oscillation period, so as to obtain the current oscillation period.

[0057] With such a setting, the actual test tube oscillation process is not an ideal physical situation and there will be various influencing factors. Therefore, only taking the peak acting force as the most representative impact force in the current oscillation period of the first force feedback information will generate a large system error. So, the system error is reduced through data processing, and obtaining the current oscillation period is the first step of data processing.

[0058] S312, obtaining the current period acting force information according to the first force feedback information. Wherein, the current period acting force information is the function information of the acting force and time in the current oscillation period.

[0059] It can be understood that the first force feedback information includes the acting force information of all oscillation periods from the start of the test tube oscillation device to the current time. Obtaining the current period acting force information of the current oscillation period from it, the current period acting force information can be a function of acting force - time, and the time interval of the function is the current oscillation period.

[0060] With such a setting, removing the acting force information of other useless oscillation periods can improve the efficiency of data processing.

[0061] S313, obtaining the target acting force according to the current period acting force information and the first interval. Wherein, the value of the first interval is a preset constant multiplied by the current oscillation period, and the center point of the first interval is the maximum value of the acting force in the current period acting force information.

[0062] It can be understood that the coordinates of the peak force point are found in the current cycle force information. Let t1 be the time coordinate of the peak point. The definite integral of the current cycle force information is calculated. The integration range of the definite integral is the first interval. The first interval is centered on t1, and the interval size is a preset constant ratio of the current oscillation period. For example, the interval size can be the oscillation period / 4. The target force is equal to the integral result divided by the interval size, which means the target force is equal to the average force of the current cycle force information in the first interval. There is also a possibility that the range of the first interval may exceed the value range of the current cycle force information. The range of the first interval can be reduced so that the range of the first interval is within the value range of the current cycle force information. It is also possible to expand the value range of the current cycle force information from the first force feedback information so that the value range of the current cycle force information includes the range of the first interval.

[0063] With such a setting, the definition of the target force is changed from a point to the average force of the range of the first interval around the peak point, which can prevent the peak force from being too high or too low due to accidents, and further prevent the result of the first impact ratio from fluctuating too much, which is beneficial to improving the stability and accuracy of the first impact ratio.

[0064] S320. Divide the target force by the first mass to obtain the first impact ratio.

[0065] It can be understood that the obtained target force is divided by the first mass to obtain the first impact ratio.

[0066] With such a setting, the accurate first impact ratio can be obtained quickly.

[0067] S400. Obtain the first oscillation acceleration according to the first oscillation frequency and the first oscillation amplitude. The first oscillation acceleration refers to the acceleration of the ideal fluid when the test tube oscillation device oscillates the test tube filled with the ideal fluid in the first oscillation mode.

[0068] It can be understood that during the oscillation of the test tube, the liquid in the test tube either oscillates synchronously with the test tube or cannot oscillate synchronously due to too high viscosity. When the liquid oscillates synchronously, the first oscillation acceleration of the synchronously oscillating liquid can be calculated according to the formula ( refers to the oscillation angular velocity, = the first oscillation frequency / 2π, and r refers to the first oscillation amplitude). If the liquid does not oscillate synchronously, the acceleration of the liquid in the test tube will be less than the first oscillation acceleration. The first oscillation acceleration can be used to assist in judging whether the liquid oscillates synchronously.

[0069] With such a setting, the oscillation state of the liquid in the test tube can be judged by combining the first impact ratio and the first oscillation acceleration, so as to adjust the oscillation mode.

[0070] S500. Adjust the oscillation mode of the test tube oscillation device according to the first impact ratio and the first oscillation acceleration.

[0071] It can be understood that the liquid in the test tube will generate an impact force on the test tube wall. The impact force (where m is the mass of the liquid and a is the acceleration of the liquid), and the first impact ratio = F / m. Therefore, ideally, when the first impact ratio is greater than or equal to the first oscillation acceleration, it means that the liquid in the test tube oscillates synchronously. If the first impact ratio is less than the first oscillation acceleration, it means that the liquid in the test tube does not oscillate synchronously. However, in reality, the comparison between the first impact ratio and the first oscillation acceleration needs to be multiplied by a constant to account for energy consumption such as internal energy. For example, when the first impact ratio is greater than or equal to a × the first oscillation acceleration, it means that the liquid in the test tube oscillates synchronously, and a < 1. When the liquid oscillates synchronously, it means that the oscillation mode of the test tube oscillation device can also increase the oscillation frequency. If the liquid does not oscillate synchronously, it means that the oscillation mode of the test tube oscillation device needs to slow down the oscillation frequency.

[0072] With such a setting, it is possible to adjust the oscillation mode of the test tube oscillation device according to liquids of different viscosities.

[0073] In a possible implementation, in step S500, adjusting the oscillation mode of the test tube oscillation device according to the first impact ratio and the first oscillation acceleration includes:

[0074] S510. When the first impact ratio is less than or equal to the first threshold multiplied by the first oscillation acceleration, perform a first adjustment. Here, the first adjustment means reducing the oscillation frequency of the test tube oscillation device and increasing the oscillation amplitude of the test tube oscillation device so that the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is a fixed value.

[0075] It can be understood that the first threshold is used to balance energy losses such as internal energy, and the first threshold is less than 1. The diameter of the test tube will affect the amount of internal energy generated when the liquid oscillates. The value of the first threshold can be determined through experiments for different test tube diameters. The experiment can be to oscillate a fixed liquid in a fixed oscillation mode (ensuring that the liquid oscillates synchronously), with the variable being the test tube diameter, and the measured quantities being the impact ratio and the oscillation acceleration. The ratio of the two measured quantities is the value of the first threshold. When the first impact ratio is less than or equal to the first threshold multiplied by the first oscillation acceleration, the liquid in the test tube does not oscillate synchronously. At this time, the first adjustment is applied. The first adjustment uniformly reduces the oscillation frequency of the test tube oscillation device to ensure a linear change in the oscillation mode. However, according to it is known that when the oscillation frequency is uniformly reduced, the acceleration of the liquid changes non-linearly. Therefore, make r increase uniformly so that is a fixed value, and at this time, both the oscillation frequency and the acceleration of the liquid change linearly and uniformly.

[0076] With such a setting, both the oscillation frequency and the acceleration of the liquid change linearly and uniformly, which can make the adjustment process of the test tube oscillation device more regular and controllable, and is beneficial to improving the effectiveness of the test tube oscillation device.

[0077] Optionally, in step S510, the method further includes:

[0078] S511, when the first impact ratio is less than or equal to the first threshold multiplied by the first oscillation acceleration, divide the first oscillation acceleration by the first impact ratio to obtain a second ratio.

[0079] It can be understood that it is judged whether the first impact ratio is within the range of (0, a] (a = the first threshold multiplied by the first oscillation acceleration). When it is within the range of (0, a], it means that the test tube oscillation device will perform the first adjustment. However, in the range of (0, a], when the first impact ratio is close to 0 and close to a, if the same first adjustment is performed, it will lead to too large an error in the adjustment process and cannot meet the requirements of dynamic adjustment. Therefore, divide the first oscillation acceleration by the first impact ratio to obtain a second ratio, and the second ratio is used to represent the specific range size situation between the first oscillation acceleration and the first impact ratio.

[0080] With such a setting, the adjustment process of the test tube oscillation device is made more reasonable.

[0081] S512, when the second ratio is less than or equal to the second threshold, the first adjustment is used to indicate that the oscillation frequency of the test tube oscillation device decreases at a first rate. Wherein, the second threshold is greater than 0 and less than the first threshold.

[0082] It can be understood that the second threshold can be a variable and can be equal to 0 + C1 / 2 (C1 refers to the first threshold). When the second ratio is less than or equal to the second threshold, it means that the gap between the first oscillation acceleration and the first impact ratio is relatively large. Therefore, the first adjustment can decrease the oscillation frequency at a relatively large first rate.

[0083] With such a setting, the adjustment process of the test tube oscillation device is made more reasonable.

[0084] S513, when the second ratio is greater than the second threshold, the first adjustment is used to indicate that the oscillation frequency of the test tube oscillation device decreases at a second rate. Wherein, the second rate is less than the first rate.

[0085] It can be understood that when the second ratio is greater than the second threshold, it means that the gap between the first oscillation acceleration and the first impact ratio is relatively small. Therefore, the first adjustment can decrease the oscillation frequency at a relatively small first rate.

[0086] With such a setting, the adjustment process of the test tube oscillation device is made more reasonable.

[0087] S520. When the first impact ratio is greater than the first threshold multiplied by the first oscillation acceleration, a second adjustment is performed. Here, the second adjustment means increasing the oscillation frequency of the test tube oscillation device and decreasing the oscillation amplitude of the test tube oscillation device so that the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is a constant value.

[0088] It can be understood that when the first impact ratio is greater than the first threshold multiplied by the first oscillation acceleration, the liquid in the test tube oscillates synchronously. At this time, the second adjustment is applied. The second adjustment increases the oscillation frequency of the test tube oscillation device at a uniform speed to ensure a linear change in the oscillation mode. However, according to it is known that when the oscillation frequency is increased uniformly, the acceleration of the liquid changes non-linearly. Therefore, r is decreased uniformly so that is a fixed value. At this time, both the oscillation frequency and the acceleration of the liquid change linearly and uniformly. And the oscillation frequencies of low-viscosity liquids are downward compatible. For example, for water and honey, at the oscillation frequency at which honey can oscillate synchronously, water can also oscillate synchronously, but not vice versa. Therefore, the second adjustment cannot be subdivided like the first adjustment in steps S511, S512, and S513. The second adjustment increases the oscillation frequency at a fixed rate.

[0089] With such a setting, both the oscillation frequency and the acceleration of the liquid change linearly and uniformly, which can make the adjustment process of the test tube oscillation device more regular and controllable, and is beneficial to improving the effectiveness of the test tube oscillation device.

[0090] Optionally, the method further includes:

[0091] S610. After the first time when the test tube oscillation device adjusts the oscillation mode, a first operation is performed, and the first operation is repeated every interval of the first time. Here, the first time is N oscillation periods, N is a fixed constant, and the oscillation period is variable. The first operation is used to instruct the test tube oscillation device to adjust the current oscillation mode according to the currently obtained impact ratio and oscillation acceleration.

[0092] It can be understood that the first operation is both the step of adjusting the oscillation mode and all the previous steps. The test tube oscillation device adjusts the oscillation mode every N oscillation periods to achieve dynamic adjustment of the oscillation mode of the test tube oscillation device.

[0093] With such a setting, it is possible to adapt to liquids whose viscosity changes during oscillation, such as partially coagulated blood, etc.

[0094] Optionally, the oscillation mode of the test tube oscillation device is circular oscillation, and the oscillation direction is reversed every fixed time interval.

[0095] It can be understood that circumferential oscillation refers to an oscillation mode that causes the liquid in the test tube to rotate and form a vortex. This mode can provide stable force feedback information during the oscillation process and can reverse the oscillation direction to increase the shear force inside the liquid to fully mix the liquid.

[0096] With such a setting, the circumferential oscillation mode can have stable force feedback information, which is beneficial to improving the accuracy of the test tube oscillation device.

[0097] Optionally, when the test tube oscillation device is started, the oscillation frequency gradually increases from zero, the oscillation amplitude gradually decreases from the maximum value, and when the oscillation frequency of the test tube oscillation device increases from zero and stabilizes at the first oscillation frequency, the first force feedback information is detected again.

[0098] It can be understood that the startup process of the test tube oscillation device takes a certain amount of time. During this period, the oscillation frequency and oscillation amplitude of the test tube oscillation device are constantly changing. Therefore, it is set that the force feedback information is detected after the oscillation frequency of the test tube oscillation device is stable, and the oscillation amplitude is the maximum value when the test tube oscillation device is not started.

[0099] With such a setting, the accuracy of the test tube oscillation device can be improved.

[0100] Optionally, the test tube oscillation device includes three power levels: high, medium, and low. When in the high power level, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is the first fixed value. When in the medium power level, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is the second fixed value. When in the low power level, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is the third fixed value, and the first fixed value is greater than the second fixed value, and the second fixed value is greater than the third fixed value.

[0101] It can be understood that different power levels can be set for the test tube oscillation device to cope with different liquid mixing tasks of different masses. It can be seen that the power of the test tube oscillation device is reflected in the oscillation frequency and the oscillation amplitude. When the power of the test tube oscillation device is higher, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is also larger. Therefore, in the case of three power levels, the products of the oscillation frequency and the oscillation amplitude of the test tube oscillation device are the first fixed value, the second fixed value, and the third fixed value respectively, and the first fixed value is greater than the second fixed value, and the second fixed value is greater than the third fixed value.

[0102] With such a setting, different amounts of liquid mixing tasks can be coped with.
