[0023] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of the defoaming device 100 provided in an embodiment of this application. The defoaming device 100 includes a conveying component 10 and a vibration component 20. The conveying component 10 is used for the flow of liquid 11, which contains bubbles 12. The bubbles 12 are attached to the inner wall of the conveying component 10. The presence of bubbles 12 can affect the stability and accuracy of the liquid 11 conveying, and may even lead to some adverse consequences. For example, in some processes with high requirements for flow control accuracy, bubbles 12 may cause flow fluctuations, affecting product quality. The vibration component 20 is connected to the conveying component 10. The vibration component 20 is used to vibrate and drive the conveying component 10 to vibrate, so that at least some of the bubbles 12 are discharged from the liquid 11.

[0024] The liquid 11 can be a pharmaceutical solution, which can be an acidic solution, an alkaline solution, an organic solvent, a salt-containing solution, or a high-viscosity solution. The acidic solution can be sulfuric acid, hydrochloric acid, nitric acid, etc., which are highly corrosive and require extremely high chemical corrosion resistance from the degassing device 100. The alkaline solution can be sodium hydroxide solution, potassium hydroxide solution, etc., which are also highly corrosive and can corrode metals and some non-metallic materials. The organic solvent can be ethanol, acetone, toluene, etc., which are mostly volatile and some are flammable and explosive, thus requiring strict explosion-proof performance from the degassing device 100. The salt-containing solution can be sodium chloride solution, potassium chloride solution, etc., which may cause electrochemical corrosion to metal parts. The high-viscosity solution can be a resin solution, a polymer solution, etc., which has poor fluidity, making it more difficult for bubbles 12 to detach after adhering to it.

[0025] The conveying assembly 10 can be a valve and / or a pipe. In the same embodiment, the vibration assembly 20 can be connected to the valve or the pipe, or one vibration assembly 20 can be connected to both the valve and the pipe. Compared to a pipe, the internal structure of a valve is more complex, making it easier for air bubbles 12 to adhere. The valve has corner areas, where air bubbles 12 tend to concentrate.

[0026] In one specific embodiment, the vibration assembly 20 may include a housing 21, a filler 22, and a vibration generating element 23. Both the filler 22 and the vibration generating element 23 are located within the housing 21, and the filler covers a portion of the surface of the vibration generating element 23. The vibration generating element 23 generates vibration and drives the vibration assembly 20 and the conveying assembly 10 connected to the vibration assembly 20 to vibrate, causing at least partially any air bubbles 12 adhering to the inner wall of the valve or pipe to be discharged from the liquid 11.

[0027] The filler 22 is elastic to ensure that it can fully absorb the vibration impact generated by the vibration generating element 23, while also effectively transmitting the vibration energy. At least a portion of the filler 22 is located between the housing 21 and the vibration generating element 23. The filler 22, the housing 21, and the vibration generating element 23 are all interference-fitted, which can buffer and fix the vibration generating element 23; at the same time, it helps to fill the gap between the housing 21 and the vibration generating element 23, which helps to balance the transmission of vibration energy and transmit the vibration energy more effectively.

[0028] In some applications, the filler 22 can also exhibit excellent chemical corrosion resistance because it is exposed to environments where it may come into contact with chemical agents. Additionally, the filler 22 can possess a certain degree of heat resistance and stability to adapt to temperature changes that may occur during device operation. The filler 22 can be made of materials such as fluororubber or EPDM rubber, which are elastic and possess excellent chemical corrosion resistance and high-temperature resistance.

[0029] The vibration generating element 23 can be of various types, including but not limited to motor components or pneumatic components that generate vibration by rotation or movement, such as eccentric rotating mass micro motors and linear resonant actuators (LRAs); it can also be a piezoelectric high-frequency motor component, such as a piezoelectric actuator or an ultrasonic MEMS actuator.

[0030] The control method of the vibration component 20 can be driven by voltage or current. By adjusting the magnitude of the input voltage or current, the oscillation frequency and amplitude of the vibration element 23 can be adjusted, thereby generating different vibration detachment energies to meet the needs of bubble 12 detachment under different working conditions.

[0031] The vibration assembly 20 also includes a wire 24 and a processor 25. The wire 24 is electrically connected to the processor 25 and the vibration generating assembly. Specifically, the housing 21 has a through hole 211, and the filler 22 has a reserved channel corresponding to the direction of the wire 24. One end of the wire 24 is electrically connected to the output interface of the processor 25, and the other end of the wire 24 passes through the housing 21 and the filler 22 and is electrically connected to the input end of the vibration generating element 23. This enables the processor 25 to drive and control the vibration generating element 23 with voltage or current, and precisely adjust the oscillation frequency and amplitude of the vibration generating element 23.

[0032] The conductor 24 passes through the through hole 211 and the filler 22. The filler 22 seals the through hole 211 from the inner wall of the housing 21. The elasticity of the filler 22 also tightly wraps the conductor 24, further enhancing the sealing effect to prevent liquid 11 from contacting the vibration element 23, and to prevent the conductor 24 from being damaged by friction during vibration. The conductor can be made of corrosion-resistant and aging-resistant fluoroplastic insulated conductor 24, which has good chemical stability and can resist the erosion of chemical agents.

[0033] The processor 25 may include a function generator 251 and a power amplifier module 252. The function generator 251 is used to output electrical signals of various waveforms, such as sine waves, square waves, triangle waves, sawtooth waves, etc., to adjust the oscillation frequency and amplitude of the vibration element 23. The power amplifier 252 is used to amplify the power of the electrical signals output by the function generator 251, providing sufficient power to the vibration assembly 20, enabling the device to effectively handle the detachment of bubbles 12 of varying complexity.

[0034] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a defoaming device 100a provided in some other embodiments of this application. The defoaming device 100a may include a conveying assembly 10 and a vibration assembly 20a, the vibration assembly 20a being connected to the conveying assembly 10. Unlike the previous embodiment, the vibration assembly 20a may include a piezo actuator 26a and a processor 25a. The piezo actuator 26a is connected to the conveying assembly 10, and the processor 25a is electrically connected to the piezo actuator 26a. The processor 25a is used to control the vibration of the piezo actuator 26a. The piezo actuator 26a is used to vibrate and drive the conveying assembly 10 to vibrate, so that at least a portion of the bubbles 12 are discharged from the liquid 11.

[0035] The piezoelectric actuator 26a is a precision ceramic actuator that operates using the piezoelectric effect. The piezoelectric actuator 26a can convert electrical energy into linear expansion or contraction, achieving high-precision displacement control. The processor 25a is the same as in the previous embodiment. In the vibration assembly 20a, the piezoelectric actuator 26a receives the electrical signal amplified by the power amplifier 252 module and generates corresponding mechanical vibration according to the signal changes. It has advantages such as fast response speed, high precision, and large output force. It can generate vibration in a very short time, and the vibration frequency and amplitude can be precisely adjusted by controlling the magnitude and frequency of the input electrical signal. For example, when dealing with the problem of air bubbles 12 in different types of drug delivery pipelines, by adjusting the electrical signal input to the piezoelectric actuator 26a, it can generate vibrations adapted to different working conditions, effectively solving the problem of difficult-to-remove air bubbles 12. These characteristics of the piezoelectric actuator 26a enable the vibration assembly 20a to process air bubbles 12 quickly and accurately, greatly improving the efficiency and effectiveness of air bubble removal.

[0036] The defoaming device 100a further includes a metal coupling plate 27a, which is located on the surface of the processor 25 opposite to the conveying assembly 10, and is connected to the processor 25. The metal coupling plate 27a can be made of aluminum alloy, stainless steel, etc., and has good mechanical strength and electrical conductivity.

[0037] The vibration component 20 continuously generates vibration during operation, which may cause the connection between the vibration component 20 and the conveying component 10 to loosen after long-term use. The metal coupling plate 27a can disperse the stress caused by the vibration, ensure a long-term stable mechanical coupling between the vibration component 20 and the conveying component 10, and maintain the continuity and reliability of vibration transmission.

[0038] The metal coupling plate 27a also provides some protection for the vibration assembly 20. It prevents potentially splashing liquid 11 from directly contacting the vibration assembly 20, thus improving its resistance to chemical corrosion and extending its service life. Simultaneously, the presence of the metal coupling plate 27a facilitates adjusting the relative positions of the vibration assembly 20 and the conveying assembly 10 according to actual installation requirements, improving the overall installation flexibility of the device.

[0039] When the drug delivery pipeline starts operating, as the drug flows through the pipeline or valve, some air bubbles 12 will adhere to the inner wall of the pipeline and / or valve during the delivery process. The processor 25 controls the vibration assembly 20, for example, by using a voltage-driven method to input a certain voltage to the eccentric rotating mass micro motor. The motor starts operating under the voltage, and due to its eccentric structure, it generates centrifugal force during rotation, thus causing the entire vibration assembly 20 to vibrate. The processor 25 can adjust the motor's rotation speed by adjusting the input voltage, thereby adjusting the oscillation frequency and amplitude of the vibration element 23. After the vibration energy is transmitted to the valve and / or pipeline through the vibration assembly 20, the air bubbles 12 adhering to the inner wall of the valve and pipeline will be subjected to the vibration force, overcoming their own adhesion and detaching. The detached air bubbles 12 can then be smoothly discharged under the influence of the flowing liquid 11. When it is not necessary to discharge air bubbles 12, the processor 25 will stop inputting voltage to the vibration assembly 20, and the vibration assembly 20 will stop operating, thus avoiding unnecessary energy consumption.

[0040] In practical applications, the oscillation frequency and amplitude of the vibrating element 23 can be flexibly adjusted according to the type and viscosity of the liquid 11 and the adhesion of the bubbles 12. For example, when the viscosity of the liquid 11 is high and the adhesion strength of the bubbles 12 is large, the input voltage can be increased to accelerate the rotation speed of the eccentric rotating mass micro motor, thereby increasing the oscillation frequency and amplitude, generating greater vibration energy, and ensuring that the bubbles 12 can detach smoothly. When the viscosity of the liquid 11 is low and the adhesion strength of the bubbles 12 is small, the input voltage can be reduced to decrease the oscillation frequency and amplitude, reducing energy consumption while ensuring that the bubbles 12 can detach. In addition, the control method of the vibrating element 23 can also be adjusted accordingly for different types of vibrating elements 23. If a piezoelectric oscillation component is used, its oscillation characteristics can be changed by adjusting the magnitude of the input current to adapt to different bubble removal requirements.

[0041] When the liquid 11 is a chemical agent, the vibration component 20 needs to be able to withstand the splashing attack of the chemical agent. The housing 21 can be made of a chemically resistant material, such as polytetrafluoroethylene, to ensure long-term stable operation in the chemical liquid transportation environment. In addition, in some other application scenarios, the vibration generating element 23 needs to be sealed or enclosed to meet the explosion-proof requirements to ensure safe use in environments that may contain flammable and explosive materials.

[0042] The defoaming device 100 (or defoaming device 100a) provided in this application embodiment uses the vibration energy generated by the vibration component 20 to detach the bubbles 12 attached to the conveying component 10, allowing them to be smoothly discharged under the influence of the flowing liquid 11. This avoids the waste of a large amount of liquid 11 caused by increasing the flow rate to remove the bubbles 12, significantly reducing production and operating costs. The vibration component 20 can generate vibrations of different frequencies and amplitudes, effectively handling bubbles 12 of different sizes and adhesion strengths, ensuring that the bubbles 12 can detach from the inner walls of valves and pipes, improving the thoroughness of bubble removal. The oscillation frequency and amplitude of the vibrating element 23 can be flexibly adjusted by voltage or current, enabling the defoaming device 100 (or defoaming device 100a) to adapt to different types of liquids 11 and the bubble 12 handling needs under different conveying conditions, thus having wide applicability. The vibration component 20 is connected to the conveying component 10 without causing significant changes to the original overall structure of the liquid 11 conveying process, making installation convenient and easy to promote and apply.
