It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0033] In order to solve the above-mentioned problems in the related art, the embodiments of the present application provide a gas-liquid interface oscillation control device, method, medium and program product. Figure 1 , the gas-liquid interface oscillation control device provided in the embodiments of the present application is described in detail through specific examples.

[0034] Figure 1 Schematic diagram of the explosion of the gas-liquid interface oscillation control device provided in some embodiments of the present application is shown. Figure 1As shown, the gas-liquid interface oscillation control device may include a container 10, a stirring component 11, a driving mechanism and an air pressure control mechanism. The container 10 has a accommodating cavity 101 for accommodating a fluid. The stirring component 11 is arranged in the accommodating cavity 101. The stirring component 11 is rotatable relative to the container 10 around an axis parallel to the first direction. The stirring component 11 includes an outer wall surface, and the outer wall surface is spaced apart from the inner wall of the container 10 to form a fluid cavity. The driving mechanism is arranged outside the container 10 and is connected to the stirring component 11. The air pressure control mechanism is arranged outside the container 10 and is connected to the stirring component 11. Among them, the stirring component 11 includes a gas channel connected to the air pressure control mechanism, and air holes arranged on the outer wall surface.

[0035] The container 10 is a structural component having a housing cavity 101, which is used to hold a fluid, such as a liquid or a gas-liquid mixture. The inner wall surface of the container 10 and the outer wall surface of the stirring assembly 11 jointly define a space for the fluid to move. The first direction can refer to the axial direction of the gas-liquid interface oscillation control device. The stirring assembly 11 is a rotatable component disposed within the housing cavity 101, rotating about an axis parallel to the axial direction. The outer wall surface of the stirring assembly 11 and the inner wall surface of the container 10 are separated to form a fluid cavity, in which the fluid can flow and be stirred by the stirring assembly 11. The gas channel is an internal hollow channel that is connected to the air pressure control mechanism and is used to transmit gas. The gas hole is opened in the outer wall surface, and the gas is released from the gas channel into the fluid cavity through the gas hole, contacting the liquid to form a gas-liquid interface. The drive mechanism is disposed outside the container 10 along the first direction and connected to the stirring assembly 11. It is a mechanism for driving the stirring assembly 11 to rotate, such as a motor or servo drive. The air pressure control mechanism is used to regulate the air pressure within the gas channel, delivering gas to the gas channel and / or extracting gas from the gas channel, enabling precise control of the air pressure within the fluid chamber. The air pressure control mechanism and the stirring assembly 11 work together to control the gas-liquid interface. The control accuracy of the air pressure control mechanism affects the gas output and gas generation frequency of the pores, thereby affecting the oscillation intensity of the gas-liquid interface.

[0036] Thus, the driving mechanism drives the stirring assembly 11 to rotate around an axis parallel to the first direction, forming a controllable flow field in the fluid cavity. At the same time, the air pressure control mechanism delivers gas to the stirring assembly 11 through the gas channel, and releases the gas into the fluid cavity through the air holes on the outer wall of the stirring assembly 11, and contacts the liquid in the fluid cavity to form a gas-liquid interface. In this way, by collaboratively adjusting the stirring speed of the stirring assembly 11 and the air pressure of the delivered gas, the gas disturbance intensity and gas-liquid interface oscillation in the fluid cavity can be accurately controlled. Compared with the method of causing the gas-liquid interface to oscillate by disturbing the liquid with the sound pressure of the speaker, the collaborative mode of the driving mechanism and the air pressure control mechanism can directly and stably control the gas disturbance intensity in the fluid cavity, thereby achieving uniformity and precision of the gas-liquid interface oscillation, and effectively overcoming the problem of uneven gas-liquid interface oscillation caused by the sound pressure disturbance applied by the speaker.

[0037] In some embodiments, in order to enable the gas to enter the fluid cavity stably and evenly, the stirring assembly 11 may include a porous structure 111 and a shell structure 112 arranged outside the porous structure 111, the shell structure 112 is connected to the driving mechanism, and the shell structure 112 and the container 10 jointly define a fluid cavity; wherein the porous structure 111 is provided with a gas channel, and the shell structure 112 is provided with air holes.

[0038] Among them, the porous structure 111 is provided with multiple gas channels, which are the buffering and homogenizing structures before the gas enters the fluid cavity. The shell structure 112 is wrapped around the outside of the porous structure 111 and rotates with the drive mechanism. At the same time, the shell structure 112 and the inner wall of the container 10 jointly define the fluid cavity. The wall surface of the shell structure 112 is provided with air holes, which are the outlets for the gas to enter the fluid cavity from the gas channels of the porous structure 111.

[0039] Preferably, the material of the porous structure 111 can be a material having multiple porous channels, such as porous copper foam. The porosity of the porous copper foam can be set between 80% and 95%. Compared with opening multiple gas channels on the structure, when the gas flows in the porous copper foam, the gas will be continuously divided into multiple small airflows, effectively breaking up the areas where the flow rate or pressure distribution is originally uneven. For example, if there are local high-speed or high-pressure areas in the gas input into the stirring component 11, after passing through the porous copper foam, these uneven areas are dispersed into various porous channels under the action of turbulence, and the gas output from the gas channel will eventually become more uniform in parameters such as flow rate and pressure.

[0040] Thus, by employing a stirring assembly 11 including a porous structure 111, the uniformity and stability of gas entering the fluid chamber can be improved. Uniform airflow input ensures consistent gas disturbance intensity at all locations of the gas-liquid interface, avoiding problems such as inconsistent oscillation amplitude and localized fluctuations at the gas-liquid interface caused by uneven airflow. Furthermore, the stable and uniform airflow also facilitates synergy with the rotation of the stirring assembly 11, further improving the uniformity of gas-liquid interface oscillation.

[0041] In some embodiments, the stirring assembly 11 includes a recess formed by a depression of the outer wall surface, and a convex portion located between adjacent recesses, and multiple recesses are spaced apart in the first direction; wherein the outer wall surface includes a bottom wall of the recess, and the air hole is arranged on the bottom wall.

[0042] The concave portion is a groove-like structure formed by the outer wall being recessed inward. Multiple concave portions are spaced apart along a first direction, while convex portions are located between adjacent concave portions, providing separation and flow guidance. By placing the air holes in the concave portions, the gas released from the air holes is confined by the concave space, forming a localized buffer zone, preventing the high-speed airflow from directly impacting the liquid and affecting the stability of the gas-liquid interface.

[0043] When gas delivered by the pressure control mechanism flows into the recess through the gas channels and pores, the spatial structure of the recess forces the gas to diffuse and buffer before release. Once the gas evenly fills the recess, it forms a dense, uniform airflow. Furthermore, the presence of the protrusions isolates the airflows in adjacent recesses, preventing interference between airflows in different areas and ensuring that each recess's corresponding gas-liquid contact area receives independent and uniform gas input.

[0044] In some embodiments, the pores can be set as circular holes of 0.1mm-0.2mm. On the one hand, the amount of gas released at a single time can be limited to avoid excessive local disturbance of the gas-liquid interface due to excessive gas flow; on the other hand, the small-aperture pores allow the gas to be evenly dispersed into the liquid in the form of a thin stream rather than forming large bubbles, thereby reducing irregular impact on the gas-liquid interface.

[0045] The combination of the concave-convex structure and the tiny pores allows for uniform gas release at multiple points within the fluid cavity. The liquid in each concave region receives a consistent gas input at a consistent flow rate and pressure. This uniform airflow ensures consistent disturbance intensity at all points on the gas-liquid interface. Combined with the rotation of the stirring assembly 11, the liquid, under the dual effects of the flow field and uniform airflow, forms a stable oscillating waveform, achieving uniform regulation of gas-liquid interface oscillation.

[0046] In some embodiments, the recess gradually increases in size in the first direction, from the center of the stirring assembly 11 toward the fluid chamber. For example, the recess near the central axis of the stirring assembly 11 has a smaller size in the first, axial direction, while the recess near the outside of the fluid chamber has a larger axial size, forming an outwardly expanding groove structure. Thus, as gas flows from the air holes of the stirring assembly 11 into the recessed area, the axial size of the recess gradually increases radially, causing the gas flow space to gradually expand radially, forming a diffuse flow channel structure.

[0047] As the gas flow space expands, its flow velocity decreases as the cross-sectional area of ​​the flow channel increases. This balances the impact energy of the gas at each location on the gas-liquid interface in the radial direction perpendicular to the first direction, resulting in uniform gas disturbance in the radial direction. This uniform disturbance effectively improves the uniformity and stability of gas-liquid mixing.

[0048] In some embodiments, the protrusion includes a pointed end, the pointed end pointing toward the inner wall.

[0049] As a result, the convex portion can divide and guide the fluid during the rotation of the stirring assembly 11. When the fluid passes through the convex portion as the stirring assembly 11 rotates, the pointed end can locally accelerate the fluid and change its flow direction. During the gas-liquid mixing process, this turbulence helps to more evenly disperse the gas in the liquid, further improving the uniformity of the gas-liquid interface oscillation.

[0050] In some preferred embodiments of the present application, the recess can be set as a V-shaped groove, and the tip can be set as a V-shaped tip. For example, the width of the V-shaped groove can be set to 3.2mm-3.8mm. Within this range, it can ensure that the gas has sufficient circulation space and can form effective buffering and diffusion in the groove; the depth of the V-shaped groove is 3.2mm-3.3mm. Within this range, it can ensure that the gas is fully in contact with the liquid and mixed in the groove; the spacing between two adjacent V-shaped grooves is 0.8mm-1.2mm. This spacing setting ensures that the gas released by each groove is independent of each other and can have a moderate influence. While ensuring uniform distribution of the gas, it avoids mutual interference of the gases due to too small a spacing, or uneven mixing of the gas and liquid due to too large a spacing.

[0051] Compared to grooves and tip structures of other shapes, the V-shaped groove can use its inclined sidewalls to guide the gas to diffuse evenly into the liquid in a fan shape when the gas is released, thereby enhancing the contact area and mixing effect between the gas and the liquid. When the V-shaped tip rotates, the fluid division and diversion effects are more efficient, and regular disturbances can be formed within the fluid, further optimizing the gas-liquid mixing process. As the gas is evenly released from the center of the stirring component 11 to the outside of the fluid cavity through the V-shaped groove with gradually varying sizes, and the V-shaped tip efficiently disturbs the fluid, the uniformity of the gas-liquid interface oscillation can be effectively improved.

[0052] In some embodiments, the concave portion is provided with a hydrophobic coating, and / or the convex portion is provided with a hydrophilic coating.

[0053] Among them, there are pore hydrophilic coating and pore avoidance setting, hydrophobic coating and pore avoidance setting. If the hydrophobic coating covers the pores, the hydrophobic surface may form a liquid film near the pores due to surface tension, hindering the entry and exit of gas. By using the avoidance setting, that is, the pore position is not coated with the hydrophobic coating, ensuring that there is no hydrophobic coating on the pore surface, the resistance to gas flow can be reduced, allowing the gas to pass more smoothly. If the hydrophilic coating covers the pores, the liquid may penetrate into the pores due to strong wetting, causing the gas channel to be blocked, affecting the normal input or discharge of gas. By using the avoidance setting, that is, the pore position is not coated with the hydrophilic coating, the air permeability of the pores can be retained, ensuring smooth gas flow.

[0054] For example, the hydrophobic coating may be a fluoropolymer coating, and the hydrophilic coating may be a hydroxylated silicon oxide coating.

[0055] The hydrophobic coating can reduce the affinity of the recessed surface for liquid, reducing the adhesion of liquid to the recessed portion, making it less likely that the gas will be blocked by liquid when released through the pores. When gas enters the recessed portion, the hydrophobic surface reduces the infiltration of the liquid into the pores, ensuring a more uniform amount of gas release and reducing the difference in gas-liquid interface disturbance caused by uneven gas release. Furthermore, when the stirring assembly 11 rotates, the liquid moves toward the inner wall of the fluid chamber due to centrifugal force, reducing the amount of liquid remaining in the groove and making the oscillation of the gas-liquid interface more uniform in the radial direction.

[0056] The hydrophilic coating can enhance the interaction between the liquid and the protrusions, making it easier for the liquid to adhere and flow along the surface of the protrusions, helping to accelerate the dispersion of gas in the liquid and avoid uneven interface oscillation caused by gas aggregation.

[0057] Therefore, the hydrophobic properties of the concave parts ensure uniform gas release, and the hydrophilic properties of the convex parts enhance liquid disturbance. The two work together so that the uniform gas released by the hydrophobic concave parts enters the fluid cavity and is dispersed by the turbulent liquid driven by the hydrophilic convex parts, thus avoiding local accumulation of gas. The stable liquid film maintained by the convex parts can further constrain gas movement, so that the gas-liquid interface maintains dynamic balance during the stirring process, significantly improving the oscillation uniformity of the gas-liquid interface.

[0058] In some embodiments, the air pressure regulating mechanism includes an air supply component and / or an air extraction component; wherein the air supply component is connected to the gas channel for delivering gas to the gas channel; the air extraction component is connected to the gas channel for extracting gas from the gas channel.

[0059] The gas supply component and the gas extraction component can work independently or in conjunction. For example, the gas supply component can use a compressor to deliver gas to the fluid cavity in a positive pressure mode to actively generate gas, while the gas extraction component can use a gas tank and a vacuum pump to extract gas from the gas channel in a negative pressure mode to reduce the gas pressure in the fluid cavity.

[0060] In some preferred embodiments of the present application, the gas-liquid interface oscillation control device may further include a controller, which is equipped with a high-frequency response regulation and control system. The high-frequency response regulation and control system achieves precise control of the pressure in the gas channel by adjusting the coordinated working state of the gas supply component and the gas extraction component. The high-frequency response regulation and control system can achieve high-frequency regulation of the pressure. The control parameters of the high-frequency response regulation and control system may include:

[0061] The pressure adjustment range is set to -1 bar to 8 bar, which can achieve precise oscillation control from low frequency to high frequency;

[0062] The pressure fluctuation control accuracy is set to less than 0.02%, that is, the deviation between the actual pressure and the set value does not exceed 0.02% of the full scale. For example, when the set pressure is 5 bar, the fluctuation range is less than 0.01 bar;

[0063] The response time is set to less than 9 milliseconds, which can quickly track pressure control instructions and meet high-frequency oscillation requirements.

[0064] Therefore, through the coordination of the air supply component and the air extraction component, combined with the high-frequency response control system, the air pressure control mechanism achieves a wide range of pressure adjustment from -1 bar to 8 bar, with a control accuracy of less than 0.02% and a response speed of less than 9 milliseconds, and accurately controls the oscillation frequency and amplitude of the gas-liquid interface.

[0065] In some embodiments, the air pressure regulating mechanism includes an air supply component and an air extraction component; the air pressure regulating component also includes a valve structure, a first gas passage connecting the air supply component and the gas channel, and a second gas passage connecting the air extraction component and the gas channel; wherein the valve structure is used to control the start and stop of the air supply to the gas channel by the air supply component, and to control the start and stop of the air extraction from the gas channel by the air extraction component.

[0066] The valve structure refers to the device used to control the on / off of the gas passage, enabling the start / stop of gas supply or extraction, as well as flow regulation. Examples include solenoid valves, pneumatic valves, and proportional valves. The primary and secondary gas passages are piping systems connecting the gas supply assembly to the primary gas channel, and the gas extraction assembly to the secondary gas channel, respectively. These systems, such as high-pressure metal pipes or corrosion-resistant hoses, ensure stable gas transmission.

[0067] For example, the gas supply control of the gas supply component may include: opening a first gas passage through a valve structure, allowing gas output from the compressor to flow into the gas channel through the first gas passage and be released into the fluid chamber through the air hole; when the valve structure closes the first gas passage, gas supply stops, and the pressure in the gas channel is maintained by the residual gas in the first gas passage. The gas extraction control of the gas extraction component may include: opening a second gas passage through a valve structure, allowing a vacuum pump to extract gas in the gas channel into a gas storage tank, creating a negative pressure; when the valve structure closes the second gas passage, gas extraction stops.

[0068] Therefore, through the precise control of the first gas passage and the second gas passage by the valve structure, the air pressure control mechanism realizes the independent start and stop and coordinated switching of gas supply and gas extraction, and improves the pressure fluctuation control accuracy of the gas-liquid interface oscillation.

[0069] In some embodiments, the gas-liquid interface oscillation device may further include a liquid supply component, and the container 10 is provided with a liquid channel communicating with the fluid cavity; wherein the liquid supply component transports liquid into the fluid cavity through the liquid channel.

[0070] The liquid supply assembly is a device for delivering liquid to the fluid cavity, and may include a liquid storage tank and an infusion pump to achieve liquid delivery.

[0071] Exemplarily, the controller controls the infusion pump to extract liquid from the liquid storage tank and deliver the liquid to the fluid chamber through the liquid channel.

[0072] Thus, the liquid in the fluid cavity is transported by arranging the liquid supply component and the liquid channel.

[0073] In some embodiments, the device further comprises a liquid extraction component, which can extract liquid from the fluid chamber through the liquid channel. For example, the controller controls a liquid extraction pump to extract liquid from the fluid chamber.

[0074] The number of the liquid channels can be set to two, and the two liquid channels include an infusion channel connected to the liquid outlet pipe of the infusion pump and a liquid extraction channel connected to the liquid extraction pipe of the liquid extraction pump.

[0075] The present application also provides a gas-liquid interface oscillation control method, which is applied to the gas-liquid interface oscillation control device provided in any of the above embodiments, such as Figure 2 As shown, the gas-liquid interface oscillation control method 200 includes steps 210 to 240.

[0076] Step 210: Receive a gas-liquid interface oscillation instruction, where the gas-liquid interface oscillation instruction includes at least one of the following: a first gas-liquid interface oscillation parameter and a second gas-liquid interface oscillation parameter;

[0077] Step 220: If the gas-liquid interface oscillation instruction includes a first gas-liquid interface oscillation parameter, control the gas pressure control mechanism to deliver gas to the gas channel according to the first gas-liquid interface oscillation parameter, so that the gas enters the fluid cavity through the air hole;

[0078] Step 230: If the gas-liquid interface oscillation instruction includes a second gas-liquid interface oscillation parameter, control the gas pressure control mechanism to extract gas from the gas channel according to the second gas-liquid interface oscillation parameter, so that the gas in the fluid cavity is discharged through the pores;

[0079] Step 240 : Control the driving mechanism to drive the stirring assembly to rotate relative to the receiving member around an axis parallel to the first direction, so as to utilize the gas in the fluid cavity to disturb the liquid in the fluid cavity and drive the gas-liquid interface to oscillate.

[0080] Thus, by controlling the driving mechanism to drive the stirring assembly 11 to rotate around an axis parallel to the first direction, a controllable flow field is formed in the fluid cavity. At the same time, by controlling the air pressure control mechanism, gas is transported into the stirring assembly 11 through the gas channel, and released into the fluid cavity through the air holes on the outer wall of the stirring assembly 11, and contacts the liquid in the fluid cavity to form a gas-liquid interface. In this way, by collaboratively adjusting the stirring speed of the stirring assembly 11 and the air pressure of the transported gas, the gas disturbance intensity and gas-liquid interface oscillation in the fluid cavity can be accurately controlled. Compared with the method of causing the gas-liquid interface to oscillate by disturbing the liquid with the sound pressure of the speaker, the collaborative control of the driving mechanism and the air pressure control mechanism can directly and stably control the gas disturbance intensity in the fluid cavity, thereby achieving uniformity and precision of the gas-liquid interface oscillation, and effectively overcoming the problem of uneven gas-liquid interface oscillation caused by the sound pressure disturbance applied by the speaker.

[0081] The above steps are described in detail below.

[0082] First, regarding step 210, the gas-liquid interface oscillation instruction in the embodiments of the present application refers to an instruction for controlling the oscillation state of the gas-liquid interface, including specific parameter configurations, which can be input by the user through the software interface, triggered by an external sensor, or automatically generated by a preset program. The first gas-liquid interface oscillation parameter refers to the parameter used to control the gas supply component to deliver gas to the gas channel, such as the gas supply pressure, gas flow rate, and gas supply duration; the second gas-liquid interface oscillation parameter refers to the parameter used to control the gas extraction component to extract gas from the gas channel, such as the vacuum pressure, gas extraction rate, and gas extraction period.
