Description

Technical Field

[0001] The present invention relates to the field of ultrasonic technology, and in particular to an ultrasonic cavitation structure, method, ultrasonic equipment and controller. Background Art

[0002] The ultrasonic cavitation rod uses the ultrasonic cavitation effect generated by the propagation of ultrasonic waves in liquids to perform cavitation treatment operations. The ultrasonic cavitation effect refers to the dynamic process of growth and collapse that occurs when ultrasonic waves are transmitted in liquids and the liquids are subjected to the physical effects of stretching and compression generated by ultrasonic transmission, resulting in a large number of micro-nucleus cavitation bubbles (cavities) in the liquids. When the sound pressure reaches a certain value, these small bubbles rapidly collapse, generating high temperature, high pressure and micro-jets in the bubbles, thereby producing physical effects such as cleaning, emulsification, crushing, and dispersion and homogenization on components immersed in the liquid or particles suspended in the liquid. In the prior art, ultrasonic cavitation rods are usually customized according to the actual application scenarios of cavitation treatment operations, and each ultrasonic cavitation rod corresponds to a specific application scenario. The disadvantage of this solution is that since the ultrasonic cavitation rods need to be customized one by one according to the actual application scenarios, the customization cost is high, the frequency and power of the radiated ultrasonic waves are single, and therefore the economic efficiency is poor, and the usage scenarios cannot be switched according to demand, and the use is also extremely inconvenient.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an ultrasonic cavitation structure, including a baseband module 20, at least two power amplification modules 30 and at least two ultrasonic transducers 10; wherein, the specific number of the power amplification modules 30 and the ultrasonic transducers 10 can be set according to preset ultrasonic cavitation conditions, wherein the preset ultrasonic cavitation conditions include different target cavitation powers and target cavitation frequencies, etc.

[0031] The ultrasonic transducer 10 is used to convert the input electrical power into longitudinal mechanical vibration and output it to the baseband module 20; the preset mechanical power of the longitudinal mechanical vibration converted by each ultrasonic transducer 10 is different; that is, since the natural frequency of each component is determined by the physical parameters (density, elastic modulus, Poisson's ratio) and shape of the material, when the material and shape of an ultrasonic transducer 10 are fixed, the preset vibration frequency of the longitudinal mechanical vibration that the ultrasonic transducer 10 can convert and output is fixed, and at the same time, the preset mechanical power of the longitudinal mechanical vibration that the ultrasonic transducer 10 converts and outputs is also fixed. Therefore, each ultrasonic transducer 10 corresponds to a preset mechanical power and a preset vibration frequency. However, when another ultrasonic transducer 10 changes its material or size, the preset mechanical power of the longitudinal mechanical vibration that it converts and outputs is also converted accordingly.

[0032] The baseband module 20 is detachably connected to the ultrasonic transducer 10, and the baseband module 20 is used to output the longitudinal mechanical vibration after the conversion of the ultrasonic transducer 10; it is understandable that in the present invention, the baseband module 20 can be regarded as a universal connector, which mainly plays the role of connecting the ultrasonic transducer 10 and other modules, so as to output the longitudinal mechanical vibration after the conversion of the ultrasonic transducer 10 to other modules (such as the power amplification module 30 or the frequency conversion module 40 mentioned later). In one embodiment, the ultrasonic cavitation structure also includes a mounting bolt 60; a fifth mounting hole is provided on the end face of the baseband module 20 that is away from the first mounting hole, and a sixth mounting hole is provided on the ultrasonic transducer 10, and the ultrasonic transducer 10 is detachably connected to the baseband module 20 through mounting bolts 60 inserted into the fifth mounting hole and the sixth mounting hole at both ends. That is, in this embodiment, a sixth mounting hole is provided on different ultrasonic transducers 10. Thus, since the sixth mounting hole is adapted to the fifth mounting hole of the baseband module 20, all ultrasonic transducers 10 can be screwed to the baseband module 20 by means of mounting bolts 60 inserted into the fifth mounting hole and the sixth mounting hole at both ends, respectively, or the two can be separated after removing the mounting bolts 60 to facilitate replacement of different ultrasonic transducers 10.

[0033] Furthermore, a first limiting portion (such as a convex portion or a concave portion) may be set on the end surface of the baseband module 20 having the fifth mounting hole; a second limiting portion (such as a concave portion or a convex portion adapted to the first limiting portion) may be provided on the end surface of the ultrasonic transducer 10 having the sixth mounting hole; and the first limiting portion is adapted to the second limiting portion; therefore, when the ultrasonic transducer 10 and the baseband module 20 need to be installed, the two can be first matched and connected through the first limiting portion and the second limiting portion so that the fifth mounting hole and the sixth mounting hole are aligned, and then screwed together through the mounting bolts 60.

[0034] The power amplifier module 30 is detachably connected to the baseband module 20. The power amplifier module 30 is used to increase the preset mechanical power of the longitudinal mechanical vibration to the target cavitation power and then output it after receiving the longitudinal mechanical vibration; each of the power amplifier modules 30 corresponds to a step-increase power, and the target cavitation power is the sum of the preset mechanical power and the step-increase power; from the above, it can be seen that since the natural frequency of each component is determined by the physical parameters (density, elastic modulus, Poisson's ratio) and shape of the material, therefore, when the material and shape of an ultrasonic transducer 10 are fixed, the preset mechanical power of the longitudinal mechanical vibration can be increased by adding a power amplifier module 30 to the baseband module 20. Similarly, the step-increase power that each power amplifier module 30 can increase will also be fixed due to the limitation of the material and size of the power amplifier module 30. Therefore, each of the power amplifier modules 30 corresponds to a step-increase power. However, when another power amplifier module 30 changes its material or size, its corresponding step-increase power is also converted accordingly. Therefore, the preset mechanical power of the longitudinal mechanical vibration can be increased by replacing the power amplifier module 30, so as to finally output the target cavitation power to perform ultrasonic cavitation treatment on the target object. Furthermore, the end of the power amplifier module 30 away from the baseband module 20 is hemispherical, but it can also be set to a square or other regular or irregular shape according to needs.

[0035] In one embodiment, the ultrasonic cavitation structure further includes a connecting bolt 50; the baseband module 20 is provided with a first mounting hole, the power amplifier module 30 is provided with a second mounting hole, and the power amplifier module 30 is detachably connected to the baseband module 20 through the connecting bolt 50 whose two ends are respectively inserted into the first mounting hole and the second mounting hole. That is, in this embodiment, different power amplifier modules 30 are provided with a second mounting hole. In this way, since the second mounting hole is adapted to the first mounting hole of the baseband module 20, all the power amplifier modules 30 can be screwed to the baseband module 20 through the connecting bolt 50 whose two ends are respectively inserted into the first mounting hole and the second mounting hole, or the two can be separated after the mounting bolt 60 is removed to facilitate the replacement of different power amplifier modules 30.

[0036] The ultrasonic transducer 10, the baseband module 20 and the power amplifier module 30 connected in sequence constitute a first ultrasonic cavitation rod capable of switching the cavitation power of ultrasonic waves. Further, the first ultrasonic cavitation rod is cylindrical. It is understandable that the shape of the first ultrasonic cavitation rod can also be other shapes besides cylindrical, such as a polygonal prism, etc.

[0037] The ultrasonic cavitation structure in the above-mentioned embodiment of the present invention can be assembled under different preset ultrasonic cavitation conditions through different assembly modes (one or more of the ultrasonic transducer 10 and the power amplification module 30 are different) by replacing the modules of the ultrasonic transducer 10 and the power amplification module 30, so as to obtain different first ultrasonic cavitation rods. That is, the ultrasonic cavitation structure in the present invention is modularly designed, and different ultrasonic transducers 10 and power amplification modules 30 can be assembled according to needs, and then the ultrasonic cavitation structure (different first ultrasonic cavitation rods) and its corresponding ultrasonic cavitation method are used to output ultrasonic waves with target cavitation frequency and target cavitation power, and then the target object is subjected to ultrasonic cavitation treatment according to the preset ultrasonic cavitation conditions. The ultrasonic cavitation structure and method of the present invention can be applied to ultrasonic cavitation treatment production processes and experimental testing stages with different preset ultrasonic cavitation condition requirements (the ultrasonic parameters of the verification treatment process can be optimally configured under the preset cavitation conditions), so that an ultrasonic cavitation structure can be applied to a variety of application scenarios (different first ultrasonic cavitation rods are assembled for different application scenarios) without the need to customize ultrasonic cavitation rods for each ultrasonic cavitation condition, thereby reducing the ultrasonic cavitation test time, improving the test efficiency, saving a large number of customization costs of various types of ultrasonic cavitation rods, and having high economic practicality.

[0038] In one embodiment, as 1 and Figure 2As shown, the ultrasonic cavitation structure also includes at least two frequency conversion modules 40; the preset vibration frequency of the longitudinal mechanical vibration converted by each ultrasonic transducer 10 is different; the frequency conversion module 40 is detachably connected between the baseband module 20 and the power amplification module 30, and the frequency conversion module 40 is used to convert the preset vibration frequency of the longitudinal mechanical vibration into a target cavitation frequency after receiving the longitudinal mechanical vibration output by the baseband module 20; each of the frequency conversion modules 40 corresponds to an adjustment frequency, and the target cavitation frequency is the sum of the preset vibration frequency and the adjustment frequency; It can be seen from the above that since the natural frequency of each component is determined by the physical parameters (density, elastic modulus, Poisson's ratio) and shape of the material, therefore, when the material and shape of an ultrasonic transducer 10 are fixed, the preset vibration frequency of the longitudinal mechanical vibration can be increased by adding a frequency conversion module 40 between the baseband module 20 and the power amplification module 30. Similarly, the adjustment frequency that can be increased by each frequency conversion module 40 will also be fixed due to the material and size limitations of the frequency conversion module 40. Therefore, each of the frequency conversion modules 40 corresponds to an adjustment frequency. However, when another frequency conversion module 40 changes material or size, its corresponding adjustment frequency is also converted accordingly. Therefore, the preset vibration frequency of the longitudinal mechanical vibration can be increased by replacing the frequency conversion module 40, so as to finally output the target cavitation frequency to perform ultrasonic cavitation treatment on the target object.

[0039] The ultrasonic transducer 10, the baseband module 20, the frequency conversion module 40 and the power amplifier module 30 connected in sequence constitute a second ultrasonic cavitation rod capable of switching the cavitation power and cavitation frequency of the ultrasonic wave. Further, the second ultrasonic cavitation rod is cylindrical. It is understandable that the shape of the second ultrasonic cavitation rod can also be other shapes besides the cylindrical shape, such as a polygonal prism, etc.

[0040] The ultrasonic cavitation structure in the above embodiment of the present invention can be assembled under different preset ultrasonic cavitation conditions through different assembly modes (one or more of the ultrasonic transducer 10, the frequency conversion module 40 and the power amplification module 30 are different) by replacing the modules of the ultrasonic transducer 10, the frequency conversion module 40 and the power amplification module 30, so as to obtain different second ultrasonic cavitation rods (wherein, when the second ultrasonic cavitation rod is set not to be equipped with the frequency conversion module 40, the second ultrasonic cavitation rod at this time is the above-mentioned first ultrasonic cavitation rod), that is, the ultrasonic cavitation structure in the present invention is modularly designed, and different ultrasonic transducers 10 and power amplification modules 30 can be assembled according to needs, and then the ultrasonic cavitation structure (different second ultrasonic cavitation rods or first ultrasonic cavitation rods) and the corresponding ultrasonic cavitation method are used to output ultrasonic waves with target cavitation frequencies and target cavitation powers, and then the target object is subjected to ultrasonic cavitation treatment according to the preset ultrasonic cavitation conditions. The ultrasonic cavitation structure and method of the present invention can be applied to ultrasonic cavitation treatment production processes and experimental testing stages with different preset ultrasonic cavitation condition requirements (the ultrasonic parameters of the verification treatment process can be optimally configured under the preset cavitation conditions), so that an ultrasonic cavitation structure can be applied to a variety of application scenarios (different second ultrasonic cavitation rods or first ultrasonic cavitation rods are assembled for different application scenarios) without the need to customize the ultrasonic cavitation rod for each ultrasonic cavitation condition, thereby reducing the ultrasonic cavitation test time, improving the test efficiency, saving a large number of customization costs of various types of ultrasonic cavitation rods, and having high economic practicality.

[0041] Furthermore, if Figure 2 As shown, the connecting bolt 50 includes a first connecting bolt 501 and a second connecting bolt 502; the frequency conversion module 40 is provided with a third mounting hole and a fourth mounting hole at opposite ends thereof; the frequency conversion module 40 is connected between the baseband module 20 and the power amplification module 30; the frequency conversion module 40 is detachably connected to the baseband module 20 through a first connecting bolt 501 whose two ends are respectively inserted into the first mounting hole and the third mounting hole; the power amplification module 30 is detachably connected to the frequency conversion module 40 through a second connecting bolt 502 whose two ends are respectively inserted into the second mounting hole and the fourth mounting hole.

[0042] That is, in this embodiment, both ends of different frequency conversion modules 40 are provided with a third mounting hole and a fourth mounting hole opposite to each other. Thus, when the frequency conversion module 40 is connected between the baseband module 20 and the power amplifier module 30, since the third mounting hole is adapted to the first mounting hole of the baseband module 20, all the frequency conversion modules 40 can be screwed to the baseband module 20 through the first connecting bolts 501 inserted into the first mounting hole and the third mounting hole at both ends, or the frequency conversion module 40 is separated from the baseband module 20 after the mounting bolts 60 are removed, so as to facilitate the replacement of different frequency conversion modules 40. Furthermore, since the fourth mounting hole is adapted to the second mounting hole of the power amplifier module 30, all the frequency conversion modules 40 can be screwed to the power amplifier module 30 through the second connecting bolts 502 inserted into the second mounting hole and the fourth mounting hole at both ends, or the frequency conversion module 40 is separated from the power amplifier module 30 after the mounting bolts 60 are removed, so as to facilitate the replacement of different frequency conversion modules 40.

[0043] In one embodiment, the baseband module 20 includes a first positioning portion 201 arranged on the end face having the first mounting hole; the power amplification module 30 includes a second positioning portion 301 arranged on the end face having the second mounting hole; the frequency conversion module 40 includes a third positioning portion 401 arranged on the end face having the third mounting hole and a fourth positioning portion 402 arranged on the end face having the fourth mounting hole; the first positioning portion 201 is adapted to the second positioning portion 301 and the third positioning portion 401; the fourth positioning portion 402 is adapted to the second positioning portion 301.

[0044] In this embodiment, the first positioning portion 201 of the baseband module 20 may be a convex portion or a concave portion used to realize positioning between the baseband module 20 and the power amplifier module 30 with the second positioning portion 301; when the ultrasonic cavitation structure is assembled into the first ultrasonic cavitation rod, the second positioning portion 301 of the power amplifier module 30 is a concave portion or a convex portion adapted to the first positioning portion 201. When the ultrasonic cavitation structure is assembled into the second ultrasonic cavitation rod, the frequency conversion module 40 also needs to be docked and positioned with the first positioning portion 201 of the baseband module 20 through the third positioning portion 401; therefore, the second positioning portion 301 must also be a concave portion or a convex portion adapted to the first positioning portion 201. That is, in this embodiment, the first positioning portion 201 needs to be adapted to be docked with the second positioning portion 301 or the third positioning portion 401, so that the baseband module 20 can switch the connection with the frequency conversion module 40 or the power amplifier module 30, thereby realizing the assembly into the second ultrasonic cavitation rod or the first ultrasonic cavitation rod respectively. Understandably, when assembled into the second ultrasonic cavitation rod, the end of the frequency conversion module 40 away from the baseband module 20 needs to be docked and positioned with the second positioning portion 301 of the power amplifier module 30 through the fourth positioning portion 402; therefore, the fourth positioning portion 402 is actually consistent with the structure of the first positioning portion 201, that is, the fourth positioning portion 402 also needs to be a convex portion or a concave portion used to realize the positioning between the baseband module 20 and the power amplifier module 30 with the second positioning portion 301. In this embodiment, when two modules need to be docked and installed, the two are first docked through the two positioning portions so that the two mounting holes corresponding to the two positioning portions are aligned, and then screwed together through the connecting bolts 50.

[0045] Furthermore, the ultrasonic cavitation structure also includes a gripping portion 70 for gripping for disassembly and assembly, and the gripping portion 70 is disposed on the outer surface of one or more modules such as the baseband module 20, the power amplification module 30, the frequency conversion module 40, and / or the ultrasonic transducer 10. That is, in this embodiment, when the first ultrasonic cavitation rod or the second ultrasonic cavitation rod is assembled or disassembled using the modules in the ultrasonic cavitation structure, a disassembly tool is required. At this time, a gripping portion 70 is provided to assist the disassembly tool in performing the disassembly and assembly operation. It is understandable that, Figure 1 and Figure 2 The gripping portion 70 is a small hole arranged on the surface of the module, but the gripping portion 70 may also be a protrusion or other structure, and the number thereof may be set according to the requirements. As long as it can help the disassembly tool to better and stably grip the module to achieve disassembly and assembly.

[0046] In one embodiment, if Figure 3 As shown, the present invention provides an ultrasonic cavitation method, which outputs ultrasonic waves through the ultrasonic cavitation structure. The ultrasonic cavitation method includes the following steps S10-S80:

[0047] S10, obtaining preset ultrasonic cavitation conditions, wherein the preset ultrasonic cavitation conditions include but are not limited to different target cavitation powers and target cavitation frequencies, etc. Each ultrasonic cavitation condition corresponds to a different ultrasonic cavitation treatment process.

[0048] S20. Obtain the target cavitation frequency of the ultrasonic wave for cavitation treatment from the preset ultrasonic cavitation conditions, and obtain the preset vibration frequency of the longitudinal mechanical vibration fixedly converted and output by all ultrasonic transducers 10; that is, the preset mechanical power of the longitudinal mechanical vibration converted by each of the ultrasonic transducers 10 is different, and therefore, each ultrasonic transducer 10 corresponds to a preset mechanical power and a preset vibration frequency.

[0049] S30. When there is a preset vibration frequency that matches the target cavitation frequency, the ultrasonic transducer 10 corresponding to the preset vibration frequency is determined as the first target transducer, and the preset mechanical power of the longitudinal mechanical vibration fixedly converted and output by the first target transducer is obtained; here, the preset vibration frequency of the first target transducer matches the target cavitation frequency, which means that the preset vibration frequency of the longitudinal mechanical vibration fixedly converted and output by the first target transducer is the same as the target cavitation frequency. That is, currently only one ultrasonic transducer 10 is used to meet the target cavitation frequency output requirement of the ultrasonic wave in the preset ultrasonic cavitation condition, so there is no need to add other modules for adjusting the cavitation frequency. Moreover, after the first target transducer is determined, its corresponding preset mechanical power is also determined and cannot be changed.

[0050] S40, obtaining the target cavitation power of the ultrasonic wave for cavitation treatment and the step-increase power corresponding to each of the power amplification modules 30 from the preset ultrasonic cavitation conditions, and determining the first target power amplification module from all the power amplification modules 30 according to the target cavitation power, the step-increase power and the preset mechanical power; that is, firstly determining the difference between the target cavitation power and the preset mechanical power as the power to be increased, and then determining the target power amplification module 30 according to the power to be increased. Specifically, each power amplification module 30 corresponds to a step-increase power, and therefore, the corresponding power amplification module 30 and the power amplification module 30 with the same power to be increased are determined as the target power amplification module 30.

[0051] S50, sequentially connect and assemble the first target transducer, the baseband module 20 and the first target power amplifier module into a first ultrasonic cavitation rod; that is, assemble the first ultrasonic cavitation rod according to the assembly instructions in the above ultrasonic cavitation structure.

[0052] S60. Convert the input electrical power into longitudinal mechanical vibration having a preset vibration frequency and a preset mechanical power through the first target transducer and output it; that is, the first target transducer in the first ultrasonic cavitation rod assembled above converts the electrical power into longitudinal mechanical vibration having a preset vibration frequency and a preset mechanical power.

[0053] S70, outputting the longitudinal mechanical vibration input by the first target transducer to the first target power amplification module through the baseband module 20; that is, the baseband module 20 serves as a universal connector to output the longitudinal mechanical vibration to the first target power amplification module.

[0054] S80, increasing the preset mechanical power of the received longitudinal mechanical vibration to the target cavitation power through the first target power amplification module, and outputting ultrasonic waves with the target cavitation frequency and the target cavitation power, so as to perform ultrasonic cavitation treatment on the target object through the first ultrasonic cavitation rod. That is, the first target power amplification module increases the preset mechanical power, and the specific increased power is the step-increase power corresponding to the first target power amplification module.

[0055] The ultrasonic cavitation method in the above embodiment of the present invention can be determined by selecting the modules of the ultrasonic transducer 10 and the power amplification module 30 in the ultrasonic cavitation structure, so as to assemble the ultrasonic cavitation structure through different assembly modes (one or more of the ultrasonic transducer 10 and the power amplification module 30 are different) under different preset ultrasonic cavitation conditions to obtain different first ultrasonic cavitation rods. That is, the ultrasonic cavitation structure in the present invention is modularly designed, and different ultrasonic transducers 10 and power amplification modules 30 can be assembled according to needs, and then the ultrasonic cavitation structure (different first ultrasonic cavitation rods) and its corresponding ultrasonic cavitation method are used to output ultrasonic waves with target cavitation frequency and target cavitation power, and then the target object is subjected to ultrasonic cavitation treatment according to the preset ultrasonic cavitation conditions. The ultrasonic cavitation method of the present invention can be applied to ultrasonic cavitation treatment production processes and test test stages with different preset ultrasonic cavitation condition requirements (the ultrasonic parameters of the verification treatment process can be optimally configured in the preset cavitation conditions), so that an ultrasonic cavitation structure can be applied to a variety of application scenarios (different first ultrasonic cavitation rods are assembled for different application scenarios) without the need to customize ultrasonic cavitation rods for each ultrasonic cavitation condition, reducing the ultrasonic cavitation test time, improving the test efficiency, saving a large number of customization costs of various types of ultrasonic cavitation rods, and having high economic practicality. That is, the ultrasonic cavitation structure of the present invention adopts a modular structure design, and the cavitation frequency and cavitation power of the ultrasonic wave can be converted by replacing different modules, thereby realizing different treatment processes, such as realizing the frequency conversion of ultrasonic sub-high frequency, medium frequency, and low frequency, and also realizing the increase of ultrasonic cavitation power on the rod body of the same ultrasonic cavitation rod, which greatly facilitates the determination of process parameters in ultrasonic cavitation treatment tests.

[0056] In one embodiment, the ultrasonic cavitation structure further includes at least two frequency conversion modules 40; the frequency conversion module 40 is detachably connected between the baseband module 20 and the power amplification module 30; after the step S20, that is, after obtaining the target cavitation frequency of the ultrasonic wave for cavitation treatment from the preset ultrasonic cavitation condition, and obtaining the preset vibration frequency of the longitudinal mechanical vibration output by the fixed conversion of all ultrasonic transducers 10, the ultrasonic cavitation method further includes:

[0057] When there is no preset vibration frequency matching the target cavitation frequency, the adjustment frequency corresponding to each of the frequency conversion modules 40 is obtained; here, there is no preset vibration frequency matching the target cavitation frequency, which means that there is no ultrasonic transducer 10 whose preset vibration frequency of the longitudinal mechanical vibration outputted by the fixed conversion is the same as the target cavitation frequency. That is, currently only one ultrasonic transducer 10 is used and cannot meet the target cavitation frequency output requirement of the ultrasonic wave in the preset ultrasonic cavitation condition, so it is necessary to adjust the cavitation frequency by adding a frequency conversion module 40.

[0058] According to the target cavitation frequency, the adjustment frequency and all the preset vibration frequencies, the second target transducer and the target frequency conversion module 40 are determined from all the ultrasonic transducers 10 and all the frequency conversion modules 40, and the preset mechanical power of the longitudinal mechanical vibration fixedly converted and outputted by the second target transducer is obtained; that is, in this embodiment, the target cavitation frequency should be equal to the sum of the adjustment frequency and the preset vibration frequency, and each of the ultrasonic transducers 10 corresponds to a preset vibration frequency; each of the frequency conversion modules 40 corresponds to an adjustment frequency. Therefore, it is necessary to select the corresponding second target transducer and the target frequency conversion module 40 according to the above conditions, so that the ultrasonic wave with the target cavitation frequency is finally output. Moreover, after the second target transducer is determined, its corresponding preset mechanical power is also determined and cannot be changed.

[0059] The target cavitation power of the ultrasonic wave for cavitation treatment and the step-increase power corresponding to each of the power amplification modules 30 are obtained from the preset ultrasonic cavitation conditions, and the second target power amplification module is determined from all the power amplification modules 30 according to the target cavitation power, the step-increase power and the preset mechanical power; that is, in this step, since the target cavitation power and the preset mechanical power have been determined, the difference between the target cavitation power and the preset mechanical power is first determined as the power to be increased, and then the target power amplification module 30 is determined according to the power to be increased. Specifically, each power amplification module 30 corresponds to a step-increase power, and therefore, the corresponding power amplification module 30 and the power amplification module 30 with the same power to be increased are determined as the target power amplification module 30.

[0060] The second target transducer, the baseband module 20, the target frequency conversion module 40 and the second target power amplification module are sequentially connected and assembled into a second ultrasonic cavitation rod; that is, the second ultrasonic cavitation rod can be assembled according to the assembly instructions in the above ultrasonic cavitation structure.

[0061] The input electrical power is converted into longitudinal mechanical vibration with a preset vibration frequency and a preset mechanical power and output through the second target transducer; that is, the second target transducer in the second ultrasonic cavitation rod assembled above converts electrical power into longitudinal mechanical vibration with a preset vibration frequency and a preset mechanical power.

[0062] The longitudinal mechanical vibration input by the second target transducer is output to the target frequency conversion module 40 through the baseband module 20; that is, the baseband module 20 serves as a universal connector to output the longitudinal mechanical vibration to the second target power amplification module.

[0063] The received preset vibration frequency of the longitudinal mechanical vibration is converted into a target cavitation frequency through the target frequency conversion module 40 and output to the second target power amplification module; that is, the target frequency conversion module 40 will increase the preset vibration frequency, and the specific increased frequency is the adjustment frequency corresponding to the second target power amplification module.

[0064] The preset mechanical power of the received longitudinal mechanical vibration is increased to the target cavitation power by the second target power amplification module, and an ultrasonic wave having the target cavitation frequency and the target cavitation power is output, so as to perform ultrasonic cavitation treatment on the target object by the second ultrasonic cavitation rod. That is, the second target power amplification module increases the preset mechanical power, and the specific increased power is the step-increase power corresponding to the second target power amplification module.

[0065] The ultrasonic cavitation method in the above embodiment of the present invention can be determined by selecting the modules of the ultrasonic transducer 10, the frequency conversion module 40 and the power amplification module 30 in the ultrasonic cavitation structure, so as to realize the assembly of the ultrasonic cavitation structure through different assembly modes (one or more of the ultrasonic transducer 10, the frequency conversion module 40 and the power amplification module 30 are different) under different preset ultrasonic cavitation conditions to obtain different second ultrasonic cavitation rods. That is, the ultrasonic cavitation structure in the present invention is modularly designed, and different ultrasonic transducers 10 and power amplification modules 30 can be assembled according to needs, and then the ultrasonic cavitation structure (different second ultrasonic cavitation rods) and its corresponding ultrasonic cavitation method are used to output ultrasonic waves with target cavitation frequency and target cavitation power, and then the target object is subjected to ultrasonic cavitation treatment according to the preset ultrasonic cavitation conditions. The ultrasonic cavitation method of the present invention can be applied to ultrasonic cavitation treatment production processes and experimental testing stages with different preset ultrasonic cavitation condition requirements (the ultrasonic parameters of the verification treatment process can be optimally configured under the preset cavitation conditions), so that an ultrasonic cavitation structure can be applied to a variety of application scenarios (different second ultrasonic cavitation rods are assembled for different application scenarios) without the need to customize ultrasonic cavitation rods for each ultrasonic cavitation condition, thereby reducing the ultrasonic cavitation test time, improving the test efficiency, saving a large number of customization costs of various types of ultrasonic cavitation rods, and having high economic practicality.
