Description
Technical Field
[0001] This invention relates to the field of ultrasonic ultraviolet sterilization technology, specifically to a resonant ultrasonic ultraviolet sterilizer. Background Technology
[0002] Water microbial pollution is a key issue affecting water safety. Various microorganisms contained in drinking water, industrial wastewater, and domestic sewage may pose health risks or affect production processes. With the increasing environmental protection requirements and water safety standards, efficient and precise water sterilization technology has become an industry demand. Traditional sterilization methods need to be adapted to the characteristics of microorganisms in different water quality scenarios. There is an urgent need for a sterilization device that can specifically solve microbial pollution and adapt to complex water quality to meet the diverse needs in practical applications.
[0003] However, in existing sterilization technologies, the sensing and detection process is often interfered with by suspended impurities in the water, leading to inaccurate collection of microbial-related information and affecting the adaptability of subsequent parameter control. The control logic is fragmented, with some decision-making operations handled by the execution end, making it impossible to achieve unified and precise control. Furthermore, the matching between the ultraviolet band and the microbial-sensitive wavelength lacks systematicity, and the synergy between ultrasonic and ultraviolet parameters is insufficient. At the same time, the uneven coverage of the sound and light fields inside the sterilization chamber further affects the stability of the sterilization effect, making it difficult to meet the microbial killing needs under different water quality scenarios, resulting in limited sterilization efficiency and poor adaptability. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a resonant ultrasonic ultraviolet sterilizer. This invention utilizes the coordinated operation of a detection unit, a microfluidic unit, and a biosensor unit within the sensing module to separate microorganisms from suspended impurities as water flows through the detection channel. It accurately captures microbial characteristics and turbidity-related signals, which are then analyzed and converted into unified electrical signals by the biosensor unit and transmitted to the control center module. The control center module integrates the electrical signals with microbial characteristic database parameters to generate ultrasonic and ultraviolet parameter control commands. This ensures that the sterilization parameters are precisely matched to the characteristics of the microorganisms in the current water body, allowing the microorganisms to be effectively killed under the synergistic effect of ultrasound and ultraviolet light, guaranteeing the targeted and thorough sterilization process.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a resonant ultrasonic ultraviolet sterilizer, the sterilizer comprising:

[0012] Furthermore, in the sensing and detection module, the collected information on the water to be sterilized includes the type, concentration, and turbidity of microorganisms. The specific steps of the collection process are as follows: the water to be sterilized flows through the detection channel of the microfluidic biosensor, the detection unit contacts the water, and collects the specific structure of microorganisms and the physical characteristics of turbid suspended particles. At the same time, the microfluidic unit separates microorganisms from suspended impurities. The detection unit transmits the collected microorganism specific structure signal and turbidity physical characteristic signal to the biosensing unit for analysis and processing, converting them into microorganism type information, concentration information, and turbidity information. After preliminary processing of the three types of information, they are integrated into a unified transmittable electrical signal.
[0013] Furthermore, in the control center module, the transmitted electrical signal is received and preprocessed. Microbial characteristic parameters corresponding to the preprocessed electrical signal are retrieved from the microbial characteristic database, including the reference ultrasonic resonance frequency, reference ultrasonic resonance power, reference ultraviolet absorption peak value, and reference ultraviolet irradiation duration. The preprocessed electrical signal is compared with the retrieved microbial characteristic parameters, and the final target ultrasonic resonance frequency is calculated using the target ultrasonic resonance frequency matching formula.

[0018] Furthermore, in the ultrasonic action module, ultrasonic wave generating components are uniformly distributed and installed on the four sides of the sterilization chamber, with consistent spacing between adjacent ultrasonic wave generating components, controlling the ultrasonic waves to form a uniformly covering sound field within the sterilization chamber; based on the final target ultrasonic resonance frequency and final target ultrasonic resonance power parameters in the ultrasonic parameter control command, the working state of the ultrasonic wave generating components is adjusted through the ultrasonic drive circuit to adjust the ultrasonic resonance frequency to the final target ultrasonic resonance frequency, and simultaneously adjust the ultrasonic resonance power to the final target ultrasonic resonance power.
[0019] Furthermore, in the ultraviolet (UV) irradiation module, the UV generating component includes multiple UV emitting elements with different fixed wavelengths. Each UV emitting element is independently equipped with a UV driving circuit and a switch control unit, and the UV driving circuit has a built-in timing unit. Based on the target UV wavelength and the final UV irradiation duration in the UV parameter control command, the corresponding UV driving circuit activates the UV emitting element of the corresponding target UV wavelength. The timing unit counts down based on the final UV irradiation duration, maintaining the luminous state of the UV emitting element until the countdown ends.
[0020] Compared with existing technologies, this resonant ultrasonic ultraviolet sterilizer has the following beneficial effects:
[0021] I. This invention utilizes the synergistic cooperation of the detection unit, microfluidic unit, and biosensor unit within the sensing module to separate microorganisms from suspended impurities as water flows through the detection channel. It precisely captures microbial characteristics and turbidity-related signals, which are then analyzed and converted into unified electrical signals by the biosensor unit and transmitted to the control center module. The control center module integrates these electrical signals with parameters from the microbial characteristic database to generate ultrasonic and ultraviolet parameter control commands. This ensures that the sterilization parameters are precisely matched to the characteristics of the microorganisms in the current water body, allowing the microorganisms to be effectively killed under the synergistic effect of ultrasound and ultraviolet light, guaranteeing the targeted and thorough sterilization process.
[0022] Second, this invention constructs a uniformly covered sound field and light field by using the reflective layer design of the cavity support module, combined with the uniformly distributed ultrasonic wave generating components in the ultrasonic action module and the multi-band ultraviolet emitting elements in the ultraviolet action module. The control center module generates corresponding execution commands, and the ultrasonic action module and ultraviolet action module accurately respond to the commands to adjust their working state.

[0028] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0029] Example 1:
[0030] In the scenario of sterilization of drinking water in residential communities, the drinking water must undergo sterilization treatment to meet residents' drinking standards. The sterilization chamber is made of food-grade 304 stainless steel to prevent secondary pollution of the drinking water. The inlet of the sterilization chamber connects to the main water supply pipe of the community, and the outlet connects to the branch water supply pipes of each household in the community. The intelligent electric regulating valves at the inlet and outlet can flexibly adjust the inflow and outflow rates of water according to the water demand of the community at different times. Figure 1As shown; during the morning peak water usage period, residents' water demand is high, so the inflow and outflow rates are increased to ensure that the water remains in the cavity for a reasonable time; during the nighttime off-peak water usage period, water demand decreases, so the inflow and outflow rates are reduced to extend the water's residence time in the cavity and ensure the sterilization effect; the inner wall of the sterilization cavity is equipped with a high-reflectivity aluminum reflective layer, which can effectively reflect ultrasonic waves and ultraviolet rays, allowing ultrasonic waves to form multiple reflections in the cavity and ultraviolet rays to achieve full coverage irradiation, eliminating sterilization dead spots.
[0031] The microfluidic biosensor arranged inside the water inlet of the sterilization chamber includes a detection unit, a microfluidic unit, and a biosensing unit. When the drinking water to be sterilized flows through the detection channel, the detection unit comes into contact with the water and captures the specific structure of microorganisms and the physical characteristics of turbidity suspended particles. Common pathogens may be present in drinking water. The microfluidic unit effectively separates the microorganisms from the suspended impurities in the water to avoid interference from the suspended impurities with the detection results. Subsequently, the detection unit transmits the collected microbial specific structure signals and turbidity physical characteristic signals to the biosensing unit. The biosensing unit processes the signals and converts them into specific information on microbial species, concentration, and turbidity. Then, the three types of information are initially integrated and converted into a unified transmittable electrical signal for transmission.
[0032] Upon receiving the transmitted electrical signal, the control unit with the built-in microbial characteristic database first preprocesses the signal to remove interfering components. Since the drinking water in the community is directly related to residents' health, thorough sterilization must be ensured. Therefore, it retrieves the reference ultrasonic resonance frequency, reference ultrasonic resonance power, reference ultraviolet absorption peak value, and reference ultraviolet irradiation duration corresponding to the preprocessed electrical signal from the microbial characteristic database. The information in the preprocessed electrical signal is compared with the retrieved reference parameters, and the final target ultrasonic resonance frequency is calculated using the target ultrasonic resonance frequency matching formula. The target ultrasonic resonance frequency matching formula is as follows: ,in, The ultimate target ultrasonic resonance frequency, The reference ultrasonic resonance frequency, The concentration correction coefficient for ultrasonic resonance frequency was determined statistically based on historical concentration data of similar microorganisms collected by a microfluidic biosensor. For concentration information, For turbidity information, The ultrasonic resonance frequency turbidity correction coefficient is statistically determined based on historical turbidity monitoring data under different water quality scenarios; the final target ultrasonic resonance power is determined using the ultrasonic resonance power calculation formula, which is: ,in, The ultimate goal is ultrasonic resonance power. As the reference ultrasonic resonance power, The power concentration correction coefficient is statistically determined based on historical concentration data of similar microorganisms collected by a microfluidic biosensor. Simultaneously, the baseline UV absorption peak is corrected for turbidity using the target UV absorption peak correction formula, which is: ,in, The corrected target UV absorption peak. The baseline ultraviolet absorption peak, The ultraviolet band turbidity correction coefficient is determined statistically based on historical data on the correlation between ultraviolet absorption peak and turbidity under different water quality scenarios. The turbidity information is used; the final irradiation duration is obtained through the ultraviolet irradiation duration calculation formula, which is: ,in, This is the final duration of ultraviolet irradiation. As a baseline, the duration of ultraviolet radiation exposure The concentration influence coefficient over time was determined statistically based on historical concentration data of similar microorganisms collected by microfluidic biosensors. The duration-based turbidity influence coefficient was statistically determined based on historical turbidity monitoring data under different water quality scenarios. By comparing the corrected ultraviolet absorption peak with each fixed band of the ultraviolet generator, the band with the smallest wavelength difference was selected as the target ultraviolet band. Finally, ultrasonic parameter control commands containing the final target ultrasonic resonance frequency and final target ultrasonic resonance power, as well as ultraviolet parameter control commands containing the target ultraviolet band and the final ultraviolet irradiation duration, were generated. Figure 2 As shown.
[0033] The ultrasonic generating components are evenly distributed and installed on the four sides of the sterilization chamber, with the spacing between adjacent components remaining consistent to ensure that the ultrasonic waves form a uniformly covering sound field within the chamber. Based on the ultrasonic parameter control commands, the working state of the ultrasonic generating components is adjusted through the ultrasonic drive circuit, precisely regulating the ultrasonic resonance frequency and power. The ultrasonic waves propagate within the chamber, destroying the cell structure of microorganisms through the resonance effect, thereby achieving a sterilization effect. The uniformly covering sound field ensures that the water in all locations within the chamber receives effective ultrasonic action.
[0034] The ultraviolet (UV) generating components are arranged at the top and bottom of the sterilization chamber, comprising multiple UV emitting elements with different fixed wavelengths. Each UV emitting element is independently equipped with a UV driving circuit and a switch control unit, and the UV driving circuit has a built-in timing unit. Based on the UV parameter adjustment command, the UV emitting element of the target UV wavelength is activated through the corresponding UV driving circuit. The timing unit counts down according to the final UV irradiation duration. During the countdown, the UV light, under the action of the reflective layer, achieves full coverage irradiation of the drinking water in the chamber, effectively destroying the nucleic acid structure of microorganisms and further enhancing the sterilization effect. After the countdown ends, the timing unit automatically controls the UV emitting element to stop emitting light, completing the sterilization treatment of this batch of drinking water.
[0035] In summary, in the scenario of sterilizing drinking water in residential communities, the sterilization chamber is made of food-grade 304 stainless steel. The inlet connects to the main water supply pipeline of the community, and the outlet connects to the branch pipe of each household. The flow control valve adjusts the inflow and outflow rates of water according to the water demand at different times. The inner wall of the sterilization chamber is equipped with a reflective layer. The microfluidic biosensor on the inner side of the inlet collects information related to microorganisms and turbidity in the water through the detection unit, microfluidic unit, and biosensing unit, and converts it into electrical signals. Then, it processes the electrical signals in combination with the microbial characteristic database and generates corresponding control commands. The ultrasonic wave generator and the ultraviolet light generator operate according to the corresponding control commands. With the help of the reflective layer, multiple reflections of ultrasonic waves and full coverage of ultraviolet light irradiation are achieved, which effectively kills pathogenic bacteria in the water and ensures the safety of residents' drinking water.
[0036] Example 2:
[0037] In industrial circulating cooling water sterilization scenarios, the sterilization chamber is made of corrosion-resistant and high-temperature-resistant titanium alloy, adapting to the harsh operating conditions of industrial circulating cooling water. The inlet connects to the industrial circulating cooling water return pipeline, and the outlet connects to the circulating cooling water supply pipeline. Flow control valves at the inlet and outlet can adjust the inflow and outflow rates of water according to different industrial production loads. When the production load is high and the demand for circulating cooling water is large, the inflow and outflow rates are increased to ensure that the water maintains a reasonable residence time in the chamber. When the production load is low, the inflow and outflow rates are reduced to extend the residence time of water in the chamber and ensure the sterilization effect. The inner wall of the chamber is equipped with a reflective layer, which is precisely matched with the ultrasonic wave generator and ultraviolet light generator to effectively reflect ultrasonic waves and ultraviolet light. This allows the ultrasonic waves to form multiple reflections in the chamber, and the ultraviolet light to achieve full coverage irradiation, ensuring the sterilization effect.
[0038] The microfluidic biosensor arranged inside the water inlet of the sterilization chamber includes a detection unit, a microfluidic unit, and a biosensing unit. When industrial circulating cooling water flows through the detection channel, the detection unit is in full contact with the water, collecting the specific structure of microorganisms and the physical characteristics of turbid suspended particles. Since there are many suspended impurities in industrial circulating cooling water, the microfluidic unit effectively separates microorganisms from suspended impurities, ensuring that the detection unit can accurately collect microorganism-related signals. The detection unit transmits the collected signals to the biosensing unit, which processes them and converts them into information on microorganism type, concentration, and turbidity. The three types of information are then initially integrated and processed into a unified transmittable electrical signal before transmission.
[0039] Upon receiving the transmitted electrical signal, the control unit with a built-in microbial characteristic database first preprocesses the signal to filter out irrelevant signals such as electromagnetic interference in the industrial environment. The sterilization effect of industrial circulating cooling water directly affects the service life and production efficiency of equipment. If microorganisms are not effectively killed, it will lead to scaling on the inner wall of pipes and equipment corrosion, increasing maintenance costs and production risks. Therefore, the reference ultrasonic resonance frequency, reference ultrasonic resonance power, reference ultraviolet absorption peak value, and reference ultraviolet irradiation duration corresponding to the preprocessed electrical signal are retrieved from the microbial characteristic database. The relevant information in the preprocessed electrical signal is compared and analyzed with the retrieved reference parameters, and the final target ultrasonic resonance frequency is calculated using the target ultrasonic resonance frequency matching formula. The target ultrasonic resonance frequency matching formula is as follows: The final target ultrasonic resonance power is determined using the ultrasonic resonance power calculation formula, which is as follows: Simultaneously, the turbidity of the reference ultraviolet absorption peak is corrected using the target ultraviolet absorption peak correction formula, which is as follows: The final irradiation duration is obtained through the ultraviolet irradiation duration calculation formula, which is as follows: The modified ultraviolet absorption peak is compared with each fixed band of the ultraviolet generating component. The band with the smallest wavelength difference is selected as the target ultraviolet band. Finally, ultrasonic parameter control commands containing the final target ultrasonic resonance frequency and the final target ultrasonic resonance power are generated, as well as ultraviolet parameter control commands containing the target ultraviolet band and the final ultraviolet irradiation duration. Figure 3 As shown.
[0040] The ultrasonic generating components are evenly installed on the surrounding side walls of the sterilization chamber, with reasonable spacing between adjacent components to ensure a uniform sound field within the large-volume chamber. Based on ultrasonic parameter control commands, the ultrasonic driving circuit adjusts the operating parameters of the ultrasonic generating components, regulating the ultrasonic resonance frequency and power to the final set values. The ultrasonic waves propagate within the chamber and generate a resonance effect, powerfully destroying the cell structure of microorganisms and effectively killing microorganisms in the water. Simultaneously, under the action of the reflective layer, the ultrasonic waves are reflected multiple times within the chamber, further enhancing the uniformity and thoroughness of sterilization.
[0041] The ultraviolet (UV) generating components are arranged at the top and bottom of the sterilization chamber, containing multiple UV emitting elements with different fixed wavelengths to meet the diverse sterilization needs of industrial circulating cooling water. Each UV emitting element is independently equipped with a UV drive circuit and a switch control unit, and the UV drive circuit has a built-in timing unit. Based on the UV parameter adjustment command, the UV drive circuit of the corresponding target UV emitting element is activated, and the UV emitting element of that wavelength begins to emit light. The timing unit counts down according to the final UV irradiation duration. During this period, the UV light achieves full coverage irradiation of the industrial circulating cooling water in the chamber under the action of the reflective layer, destroying the nucleic acid of microorganisms and preventing their reproduction. After the countdown ends, the timing unit controls the UV emitting element to turn off, completing the sterilization process of the industrial circulating cooling water and ensuring that the circulating cooling water will not affect the normal operation of the equipment due to microbial growth in subsequent use.
[0042] In summary, in industrial circulating cooling water sterilization scenarios, the sterilization chamber is made of corrosion-resistant and high-temperature-resistant titanium alloy. The inlet connects to the circulating water return pipeline, and the outlet connects to the water supply pipeline. The flow control valve adjusts the water flow rate according to the production load. The reflective layer on the inner wall of the chamber is compatible with the ultrasonic and ultraviolet generating components. The microfluidic biosensor inside the inlet separates microorganisms and suspended impurities in the water, collects relevant information, and converts it into electrical signals. Based on the built-in microbial characteristic database, the electrical signals are processed to generate corresponding control commands. Based on the corresponding control commands, the ultrasonic generating component forms a uniform sound field, and the ultraviolet generating component switches to the appropriate wavelength and controls the irradiation time. Together with the reflective layer, thorough sterilization is achieved, preventing microbial growth that could lead to equipment corrosion and scaling, and ensuring efficient production operation.
