Description

Technical Field

[0001] This application relates to the field of beer machine control technology, and more specifically, to an automatic mosquito-proof beer machine based on an air curtain barrier and its control method. Background Technology

[0002] In open environments such as outdoor dining, night market stalls, and open-air bars, beer vending machines are widely popular due to their convenience. However, the sweetness and aroma of beer easily attract mosquitoes, especially in the hot summer. Once these insects fly into the dispensing spout, the cups, or even land directly on the exposed beer surface, it not only seriously affects food hygiene and reduces the customer's experience, but also damages the reputation of the business.

[0003] Currently, existing technologies for addressing mosquito problems in beer dispenser areas typically employ chemical repellents or physical covers. Chemical repellents pose a potential risk of food contamination, may alter beer flavor, and could even present safety hazards. Fixed physical covers, such as mesh screens or lids, must be removed when customers dispense beer, which is not only inconvenient and tedious to clean, but also allows mosquitoes a brief opportunity to enter, making it difficult to achieve effective and sustained insect control. For example, in an open-air beer garden on a summer evening, if mosquitoes are flying around or falling into the beer dispenser's cup while customers are enjoying their beer, it will greatly diminish their enjoyment. Traditional mesh screens or lids must be removed during dispensing, providing mosquitoes with a brief opportunity to invade.

[0004] Furthermore, existing wide-area mosquito repellent devices suffer from inconsistent mosquito control, high energy consumption, and an excessively wide range that may cause the repellent substance to spread into food areas, resulting in unnecessary cross-contamination. These solutions fail to effectively address mosquito protection in food contact areas such as beer dispensers, and cannot achieve dynamic, effective, and precise physical isolation of the dispensing spout, glasses, and exposed beer surfaces without introducing chemical contamination, affecting beer quality, or compromising ease of use. Simultaneously, current technologies lack a protective method that can automatically adjust according to the usage environment and operational stage to achieve consistent hygiene protection, ease of operation, and energy efficiency optimization. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides an automatic mosquito-repellent beer dispenser based on an air curtain barrier and its control method. The aim is to solve the technical problems of existing beer dispensers being susceptible to mosquito infestation in open environments, the risk of food contamination from traditional mosquito prevention methods, inconvenient operation and poor insect prevention effect, and the lack of dynamic, precise, efficient and energy-optimized mosquito prevention solutions.

[0006] In a first aspect, this application provides an automatic mosquito-repellent beer dispenser control method based on an air curtain barrier, applied to an air curtain generating device installed above the beer dispenser's outlet, comprising: When a user's action of pouring wine is detected, a start signal is generated; Based on the activation signal, the air curtain generator is controlled to form an air curtain barrier in the beer dispensing area of ​​the beer machine to block mosquitoes. Acquire environmental parameters and adjust the strength and / or shape of the air curtain barrier based on these parameters.

[0007] The above solution enables dynamic and physical mosquito control in the beer dispenser area, effectively addressing the shortcomings of traditional mosquito control methods and improving food hygiene and safety as well as user experience.

[0008] Furthermore, the step of generating a start signal when a user's action of pouring wine is detected includes: The pressing action of the handle is detected by a sensor installed in the handle of the beer dispenser, or the approach action of the cup or the user's hand is detected by a non-contact distance sensor installed in the dispensing area. An activation signal is generated when a pressing action on the handle, or an approach action of the cup or the user's hand is detected.

[0009] The above solution enables accurate recognition of users' actions of pouring wine, ensuring that the air curtain barrier is activated in a timely manner when needed, thereby improving the system's response speed and intelligence level.

[0010] Furthermore, the step of detecting the approach of the glass or the user's hand using a non-contact distance sensor located in the dispensing area includes: It can detect the distance between the wine sill area and the object in front, as well as the approach speed of the object in front, in real time. When the distance is consistently less than the first preset threshold and the approach speed of the object in front exceeds the second preset threshold, it is determined to be an approaching action of a cup or the user's hand.

[0011] The above solution enables more accurate determination of a user's intention to purchase alcohol without contact, avoiding accidental triggering and improving the convenience of user operation and the stability of the system.

[0012] Furthermore, the environmental parameters include at least one of the following: ambient temperature and humidity obtained by a temperature and humidity sensor, mosquito activity signal obtained by an infrared activity sensor, and local wind speed obtained by a wind speed sensor set at the edge of the air curtain barrier.

[0013] The above approach enables the acquisition of multi-dimensional environmental information, providing comprehensive data support for the intelligent adjustment of the air curtain barrier and making the mosquito control effect more targeted.

[0014] Furthermore, the steps of adjusting the strength and / or morphology of the air curtain barrier according to environmental parameters include: Adjust the airflow intensity of the air curtain barrier based on ambient temperature and humidity and mosquito activity signals; And / or adjust the power of the fan and the angle of the airflow guide vanes in the air curtain generator according to the local wind speed to ensure the integrity of the air curtain barrier.

[0015] The above scheme can dynamically adjust the air curtain barrier according to actual environmental changes and mosquito activity levels, achieving precise protection and energy efficiency optimization, while maintaining the stability and integrity of the air curtain barrier.

[0016] Furthermore, the steps of adjusting the power of the fan and the angle of the airflow guide vanes in the air curtain generator according to the local wind speed include: The shape deviation of the air curtain barrier is calculated based on the wind speed deviation between the local wind speed and the preset ideal wind speed. Based on the morphological deviation, the power of the fan and the angle of the airflow guide vanes in the air curtain generator are adjusted in a coordinated manner.

[0017] The above approach allows for precise adjustments based on the actual morphological deviations of the air curtain barrier, ensuring that the barrier always maintains optimal blocking performance and improving the system's adaptability.

[0018] Furthermore, the steps for adjusting the power of the fan and the angle of the airflow guide vanes in the air curtain generator based on morphological deviation include: Calculate the Euclidean norm of the morphological deviation as the overall deformation index; The overall deformation index is input into the preset PID controller to calculate the power correction amount used to adjust the fan and the angle correction amount used to adjust the airflow guide vanes; Based on the power correction and angle correction, the power of the fan and the angle of the airflow guide vanes in the air curtain generator are adjusted in a coordinated manner.

[0019] The above solution enables precise and real-time control of the air curtain barrier's shape using a PID controller, further improving the barrier's stability and mosquito-proof effect while optimizing energy consumption.

[0020] Furthermore, the method also includes: When the user's action of ending the dispensing action is detected, an end signal is generated. Based on the end signal, after a first preset time delay, the control air curtain generating device is stopped. The action of ending the dispensing action is detected by detecting the reset action of the handle by a sensor installed in the handle of the beer dispenser or by detecting the movement of the cup or the user's hand away by a non-contact distance sensor installed in the dispensing area.

[0021] The above solution enables intelligent start-stop of the air curtain barrier, avoiding unnecessary energy consumption, while providing brief protection after the user finishes drinking, preventing mosquitoes from entering the barrier the moment the user leaves.

[0022] Furthermore, after the air curtain generating device forms an air curtain barrier in the beer dispensing area of ​​the beer machine, it includes: If the user's action to end the wine dispensing is not detected after waiting for the second preset time, a maintenance prompt message will be generated.

[0023] The above solution can promptly alert users or managers to handle abnormal situations, prevent the air curtain barrier from operating for extended periods or the beer machine from being left unattended, and improve the reliability and safety of the system.

[0024] Secondly, this application also discloses an automatic mosquito-repellent beer dispenser based on an air curtain barrier, including an air curtain generating device disposed above the beer dispenser's outlet, the air curtain generating device comprising: The motion detection and signal generation module is used to generate a start signal when the user's action of pouring wine is detected; The air curtain generating and regulating module is used to control the air curtain generating device to form an air curtain barrier in the beer dispensing area of ​​the beer machine according to the start signal, so as to block mosquitoes; it is also used to acquire environmental parameters and adjust the strength and / or shape of the air curtain barrier according to the environmental parameters.

[0025] This application discloses an automatic mosquito-repellent beer dispenser control method based on an air curtain barrier. By detecting a user's dispensing action, the method controls an air curtain generator to form an air curtain barrier in the beer dispenser's outlet area, effectively blocking mosquitoes. This solves the problems of food contamination risks associated with chemical mosquito repellents and the inconvenience and poor insect-repellent effect of physical coverings in existing technologies. Environmental parameters are adjusted accordingly to control the strength and / or shape of the air curtain barrier, achieving dynamic and precise control. This overcomes the shortcomings of existing large-area mosquito repellent devices, such as high energy consumption, wide coverage, and susceptibility to cross-contamination. This application achieves dynamic, effective, and precise physical isolation of the beer dispenser, cups, and exposed beer surface without introducing chemical pollution or affecting beer quality or ease of operation. It also automatically adjusts according to the usage environment and operational stage, unifying hygiene protection, operational convenience, and energy efficiency optimization, significantly improving the hygiene and safety of the beer dispenser and the user experience.

[0029] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] In open environments such as outdoor dining, night market stalls, and open-air bars, beer vending machines are widely popular due to their convenience. However, the sweetness and aroma of beer easily attract mosquitoes, especially in the hot summer. Once these mosquitoes fly into the dispensing spout, the cups, or even land directly on the exposed beer surface, it not only seriously affects food hygiene and reduces the customer experience but also damages the reputation of the business. Currently, to solve the mosquito problem in beer vending machine areas, existing technologies typically use chemical repellents or physical covers. Chemical repellents pose a potential risk of food contamination, may alter the beer flavor, and even pose safety hazards. Fixed physical covers, such as mesh screens or lids, must be removed when the user dispenses beer, which is not only inconvenient and tedious to clean, but also allows mosquitoes to re-enter even after removal, making it difficult to achieve an efficient and continuous insect-repelling effect. In addition, existing wide-area mosquito repellent devices have a scattered effect, high energy consumption, and their wide range may cause the repellent to spread to the food area, causing unnecessary cross-contamination. None of these solutions effectively address the issue of mosquito and insect protection in food contact areas such as beer dispensers. They fail to achieve dynamic, effective, and precise physical isolation of the dispensing spout, cups, and exposed beer surfaces without introducing chemical contamination, affecting beer quality, or compromising ease of operation. Furthermore, existing technologies lack a protective solution that can automatically adjust based on the usage environment and operational stage to ensure consistent hygiene, ease of operation, and energy efficiency.

[0032] Regarding this, firstly, see... Figure 1 This application proposes an automatic mosquito-repellent beer dispenser control method based on an air curtain barrier, applied to an air curtain generating device installed above the beer dispenser's outlet, comprising: S1. When a user's action of pouring wine is detected, a start signal is generated; S2. Based on the start signal, control the air curtain generator to form an air curtain barrier in the beer dispensing area of ​​the beer machine to block mosquitoes. S3. Obtain environmental parameters and adjust the strength and / or shape of the air curtain barrier according to the environmental parameters.

[0033] A beer dispenser typically refers to a device used for storing, cooling, and dispensing draft beer, its core function being to provide fresh, chilled beer. A beer dispenser usually includes components such as a keg, cooling system, nozzle, and dispensing spout. An air curtain generator is a device that generates directional airflow, creating an invisible air wall or barrier in a specific area to isolate the internal and external environments. It is positioned above the beer dispenser's spout and aims to create a physical barrier through high-speed airflow, effectively preventing insects from entering the dispensing area. The air curtain barrier is an airflow with a certain intensity and shape generated by the air curtain generator. Its main function is to utilize the kinetic energy and directionality of the airflow to create a physical barrier at the beer dispenser's spout that is difficult for insects to overcome, thus preventing them from approaching or entering the beer surface and the glasses. The act of dispensing beer refers to the user's operation of the beer dispenser to take beer, such as pressing the nozzle handle or placing the glass below the dispensing spout. Environmental parameters refer to external conditions that affect the effectiveness of the air curtain barrier, such as ambient temperature and humidity, insect activity levels, and local wind speed.

[0034] The core of this application lies in achieving automatic insect protection in the beer dispenser's spout area through an intelligently controlled air curtain generator. Specifically, when a user dispenses beer, the system accurately detects this action and generates a start signal. For example, a microswitch or pressure sensor can be integrated into the beer dispenser's handle; when the user presses the handle, the sensor detects the pressing action and triggers the start signal. Alternatively, an infrared or ultrasonic sensor can be deployed in the spout area; when a cup or the user's hand approaches the spout, the sensor detects the proximity and generates a start signal. Once the start signal is generated, the air curtain generator immediately activates, forming a high-speed airflow barrier in the beer dispenser's spout area. This air curtain effectively blocks insects, preventing them from flying into the spout, the cup, or contacting the beer surface. The air curtain generator can take various forms; for example, it can be a narrow outlet with a built-in small fan array, where the airflow intensity and direction can be adjusted by controlling the fan speed and angle. Furthermore, to ensure the optimal effect of the air curtain barrier under different environments, the system also acquires environmental parameters in real time. For example, ambient temperature and humidity data can be acquired using temperature and humidity sensors placed near the beer dispenser, or mosquito activity can be monitored using infrared activity sensors. Based on these environmental parameters, the system can intelligently adjust the strength and / or shape of the air curtain barrier. For instance, when the ambient temperature is high or mosquito activity increases, the airflow intensity of the air curtain barrier can be appropriately increased to provide a stronger blocking effect. The fan power and the angle of the airflow guide vanes of the air curtain generator can also be adjusted to ensure the integrity of the air curtain barrier's shape. For example, in the event of crosswinds, the blade angle can be adjusted to counteract the effects of the crosswinds and maintain the verticality of the air curtain barrier.

[0035] The overall working principle of this application is to provide continuous and effective insect protection for the beer dispenser's spout area through intelligent sensing, dynamic response, and adaptive adjustment. When a user prepares to dispense beer, the system detects the user's dispensing action, such as pressing the handle or the glass approaching, and quickly generates an activation signal. This signal acts as an instruction, activating an air curtain generator located above the beer dispenser's spout. The air curtain generator then activates, precisely forming a high-speed, directional air curtain barrier in the dispensing area. This air curtain barrier utilizes the physical barrier effect of airflow to effectively isolate insects from the surrounding environment from the dispensing area without contacting the beer or glass, thus preventing insect contamination of the beer. Furthermore, to cope with complex and changing environmental conditions, the system continuously acquires environmental parameters, such as ambient temperature and humidity, insect activity levels, and local wind speed. These parameters are analyzed in real time and used as a basis for adjusting the strength and / or shape of the air curtain barrier. For example, when the ambient temperature rises or mosquito activity increases, the system automatically enhances the airflow intensity of the air curtain barrier to provide stronger blocking force. When a localized high wind speed is detected, the system adjusts the power of the fan in the air curtain generator and the angle of the airflow guide vanes to counteract the impact of external wind on the shape of the air curtain barrier, ensuring that it always maintains a complete and effective protective state. Thus, the various technical features of this application work closely together to form a closed-loop intelligent control system, achieving dynamic, precise, and efficient mosquito protection for the beer dispenser area, fundamentally solving the limitations of traditional mosquito control solutions.

[0036] This application combines air curtain barrier technology with the use of beer dispensers and introduces an intelligent motion detection and environmental adaptive adjustment mechanism. Traditional mosquito repellent solutions, such as chemical repellents or physical coverings, have significant drawbacks, including the risk of food contamination, inconvenience in operation, or incomplete protection. For example, in an open-air beer garden on a summer evening, if mosquitoes fly around or fall into the beer dispenser's cup while customers are enjoying their beer, it will greatly diminish their enjoyment. Traditional mesh screens or lids must be removed when dispensing beer, providing mosquitoes with a brief opportunity to invade. In contrast, this application automatically generates a start signal upon detecting the user's dispensing action and controls an air curtain generator to form an air curtain barrier in the dispensing area, achieving contactless and pollution-free dynamic physical isolation. This method not only avoids the potential impact of chemicals on beer quality and human health but also eliminates the tedious step of manually operating coverings, greatly improving ease of use. Furthermore, this application acquires environmental parameters and adjusts the strength and / or shape of the air curtain barrier accordingly, allowing the mosquito repellency effect to be optimized based on actual environmental conditions. For example, when mosquito activity is high or there is external wind interference, the air curtain barrier can automatically adjust to provide stronger protection, ensuring efficient mosquito control in various complex environments. This adaptive adjustment mechanism is not found in existing technologies; it not only improves the effectiveness of protection but also optimizes energy consumption and avoids unnecessary waste. Therefore, this application significantly improves user experience and operational efficiency while ensuring food hygiene, providing an innovative and efficient solution for mosquito control in food contact areas such as beer dispensers.

[0037] Furthermore, the step of generating a start signal when a user's action of pouring wine is detected includes: The pressing action of the handle is detected by a sensor installed in the handle of the beer dispenser, or the approach action of the cup or the user's hand is detected by a non-contact distance sensor installed in the dispensing area. An activation signal is generated when a pressing action on the handle, or an approach action of the cup or the user's hand is detected.

[0038] The detection of the pressing action on the handle can be achieved by integrating a pressure sensor, microswitch, or Hall sensor inside the handle of the dispensing gun. When the user holds the dispensing gun and presses it, the sensor can detect the action in real time and output a corresponding electrical signal, which is recognized as a direct indication of the dispensing action.

[0039] In addition, the detection of the approach of a glass or the user's hand is accomplished by a non-contact distance sensor located in the dispensing area. This sensor can be an infrared distance sensor, an ultrasonic sensor, or a capacitive proximity sensor, etc., and its working principle is to continuously monitor whether an object such as a glass or the user's hand enters its detection range in front of the dispensing area. When an object is detected to enter a preset approach distance, the sensor outputs a proximity signal.

[0040] When any of the above detection methods successfully detects the pressing action of the handle or the approach action of the cup or the user's hand, the system will generate a start signal, which serves as an instruction to subsequently control the start of the air curtain generating device.

[0041] This application provides two different mechanisms for detecting the dispensing action, ensuring the system can flexibly and accurately identify the user's dispensing intention. Whether by directly sensing the mechanical operation of the dispensing gun handle or by detecting an object approaching the dispensing nozzle non-contactly, the aim is to capture the critical moment when the user is about to dispense the dispensing. Therefore, once a valid dispensing action is detected, a start signal is immediately generated, providing a reliable trigger condition for the timely activation of the air curtain barrier, ensuring that the air curtain barrier can be rapidly formed before mosquitoes can approach the dispensing nozzle.

[0042] Through the above technical solution, this application can achieve accurate and multi-mode detection of the user's beer-making actions, significantly improving the sensitivity and reliability of the system response. This dual detection mechanism not only adapts to the usage habits of different users, but also avoids the misjudgment or missed judgment that may occur with a single detection method, thereby ensuring that the air curtain barrier is activated the moment the user starts making beer, effectively blocking mosquitoes and improving the hygiene protection level of the beer machine and the user experience.

[0043] Furthermore, the step of detecting the approach of the glass or the user's hand using a non-contact distance sensor located in the dispensing area includes: It can detect the distance between the wine sill area and the object in front, as well as the approach speed of the object in front, in real time. When the distance is consistently less than the first preset threshold and the approach speed of the object in front exceeds the second preset threshold, it is determined to be an approaching action of a cup or the user's hand.

[0044] Specifically, a non-contact distance sensor is a sensor that can measure the distance to a target object without direct contact. Examples include ultrasonic sensors, infrared distance sensors, or laser rangefinders, which can monitor in real time whether an object is approaching in front of the dispensing area. Real-time detection of the distance between the dispensing area and the object in front, as well as the object's approach speed, means that the sensor continuously acquires distance data of the object in front of the dispensing area and calculates the object's approach speed based on this data.

[0045] In practical applications, the first preset threshold refers to a distance threshold. When the distance between an object and the dispensing area is less than this value, it indicates that the object has entered the potential dispensing range. For example, this threshold can be set to 5 to 15 centimeters, depending on the structure of the beer machine and the user's operating habits. The second preset threshold refers to a speed threshold. When the approaching speed of an object exceeds this value, it indicates that the object is actively approaching at a relatively high speed, rather than moving slowly or passing by accidentally. For example, this threshold can be set to 10 to 30 centimeters per second to distinguish between the user's active dispensing intention and non-dispensing operations. "Distance continuously below the first preset threshold" means that the distance value detected by the sensor is continuously lower than the first preset threshold over a period of time, rather than falling below it instantaneously, to avoid misjudgments caused by brief obstruction or accidental touch.

[0046] This application improves the accuracy and robustness of dispensing action detection by combining distance and speed dimensions and introducing a condition that the distance is consistently less than a certain threshold. Specifically, relying solely on distance is susceptible to interference from objects that pass by or briefly linger near the dispensing area, leading to unnecessary activation of the air curtain barrier. By incorporating the approaching speed of the object as a criterion, it effectively distinguishes between the user's intention to actively extend the cup or hand towards the dispensing area and situations where the object moves slowly or remains stationary within the detection area. Furthermore, the condition that the distance is consistently less than a first preset threshold further enhances the reliability of the judgment, avoiding false triggers caused by instantaneous sensor fluctuations or objects rapidly passing by. Thus, only when an object actively enters and remains within the effective detection area at a certain speed will it be considered a dispensing action, ensuring the accurate activation of the air curtain barrier.

[0047] The above solution significantly improves the accuracy and reliability of detecting user actions while dispensing beer. By comprehensively considering distance and approach speed and introducing continuous judgment, false and missed triggers can be effectively reduced, avoiding unnecessary activation of the air curtain barrier when not dispensing beer, thus saving energy and extending the lifespan of the air curtain generator. Simultaneously, it ensures that the air curtain barrier forms promptly and accurately when the user truly needs to dispense beer, effectively blocking mosquitoes and enhancing the user experience. This multi-dimensional and continuous detection mechanism makes the system's recognition of user intentions more accurate, improving the overall intelligence level of the mosquito-repellent beer dispenser control method.

[0048] Furthermore, the environmental parameters include at least one of the following: ambient temperature and humidity obtained by a temperature and humidity sensor, mosquito activity signal obtained by an infrared activity sensor, and local wind speed obtained by a wind speed sensor set at the edge of the air curtain barrier.

[0049] Environmental parameters refer to the external conditions that affect the effectiveness of the air curtain barrier in blocking mosquitoes. Specifically, ambient temperature and humidity refer to the temperature and humidity in the beer dispenser area, which can be monitored in real time by temperature and humidity sensors installed in this area. Mosquito activity signal refers to the frequency or density of mosquito activity in the beer dispenser area, which can be detected by infrared activity sensors. For example, when an infrared activity sensor detects a moving object such as a mosquito in the area, it will generate a corresponding activity signal. Local wind speed refers to the actual airflow speed within the area where the air curtain barrier is formed, which can be measured by wind speed sensors installed at the edge of the air curtain barrier to assess the stability and integrity of the air curtain barrier.

[0050] This application, by acquiring the aforementioned specific environmental parameters, provides the necessary data foundation for subsequent adjustments to the strength and / or morphology of the air curtain barrier. For example, environmental temperature and humidity, as well as mosquito activity signals, can directly reflect the survival and activity habits of mosquitoes, thereby guiding the adjustment of the airflow intensity of the air curtain barrier to more effectively block mosquitoes. Simultaneously, acquiring local wind speed allows for real-time monitoring of the actual operating status of the air curtain barrier, ensuring that it maintains the expected blocking effect even under external environmental disturbances.

[0051] Through the above technical solution, this application can comprehensively and accurately obtain key environmental information affecting the effectiveness of the air curtain barrier. This allows the air curtain barrier to be adjusted intelligently and adaptively based on actual environmental changes, rather than operating under a single, fixed mode. This not only improves the effectiveness and precision of the air curtain barrier in blocking mosquitoes but also avoids unnecessary energy waste, enhancing the mosquito-repellent performance of the beer dispenser and the user experience.

[0052] Furthermore, the steps of adjusting the strength and / or morphology of the air curtain barrier according to environmental parameters include: Adjust the airflow intensity of the air curtain barrier based on ambient temperature and humidity and mosquito activity signals; And / or adjust the power of the fan and the angle of the airflow guide vanes in the air curtain generator according to the local wind speed to ensure the integrity of the air curtain barrier.

[0053] Specifically, ambient temperature and humidity refer to the current temperature and humidity information obtained through temperature and humidity sensors. Mosquito activity signal refers to the frequency or density of mosquito activity near the beer dispenser area, detected by devices such as infrared activity sensors. Airflow intensity refers to the speed and / or volume of airflow generated by the air curtain barrier, which directly affects the barrier's effectiveness in blocking mosquitoes. When ambient temperature and humidity are high or mosquito activity signals are strong, mosquito activity usually increases, requiring a stronger airflow intensity to effectively block them. Airflow intensity can be adjusted by changing the fan speed and airflow output in the air curtain generator.

[0054] Local wind speed refers to the external airflow velocity acting on the air curtain barrier area, obtained by wind speed sensors installed at the edge of the barrier. The morphological integrity of the air curtain barrier is crucial to its blocking effect; changes in external local wind speed can cause deformation or breakage. To ensure the morphological integrity of the air curtain barrier, the power of the fan and the angle of the airflow guide vanes in the air curtain generator can be adjusted. Fan power adjustment directly affects the overall airflow output of the air curtain barrier, while adjusting the angle of the airflow guide vanes precisely controls the direction and distribution of the airflow, thereby counteracting the influence of external wind speed on the barrier's shape and maintaining a stable and continuous blocking state.

[0055] This application achieves intelligent and dynamic control of the air curtain barrier by linking environmental temperature and humidity, mosquito activity signals, and airflow intensity adjustment, as well as linking local wind speed with fan power and airflow guide vane angle adjustment. When environmental conditions such as high temperature and humidity, or mosquito activity such as high mosquito activity making mosquitoes more inclined to approach the beer dispenser, increasing airflow intensity can effectively enhance the barrier's blocking ability, thereby more effectively preventing mosquitoes from entering. Simultaneously, since the air curtain barrier is easily deformed by external airflow interference in practical applications, by real-time monitoring of local wind speed and adjusting the fan power and airflow guide vane angle accordingly, the impact of external wind force on the barrier's shape can be actively compensated, ensuring that the barrier always maintains its intended integrity and blocking effect, avoiding protective gaps caused by incomplete shape.

[0056] Through the above-described solution, this application can adaptively adjust the strength of the air curtain barrier according to actual environmental conditions and mosquito activity, thus providing a highly effective mosquito-blocking effect in various scenarios. Furthermore, by responding to and adjusting local wind speed in real time, the morphological stability of the air curtain barrier is significantly improved, effectively avoiding the problem of protective failure caused by external airflow interference. Therefore, this application not only improves the effectiveness of mosquito prevention but also optimizes the robustness and adaptability of the system, ensuring that the beer dispenser provides a clean and hygienic beer-dispensing experience in various environments.

[0057] Furthermore, the steps of adjusting the power of the fan and the angle of the airflow guide vanes in the air curtain generator according to the local wind speed include: The shape deviation of the air curtain barrier is calculated based on the wind speed deviation between the local wind speed and the preset ideal wind speed. Based on the morphological deviation, the power of the fan and the angle of the airflow guide vanes in the air curtain generator are adjusted in a coordinated manner.

[0058] Specifically, local wind speed refers to real-time wind speed data obtained through wind speed sensors installed at the edge of the air curtain barrier, reflecting the actual stress on the air curtain barrier under the current environment. The preset ideal wind speed refers to the target wind speed value determined during the design or testing phase, which ensures the air curtain barrier maintains optimal blocking effect and morphological stability. Wind speed deviation refers to the difference between the real-time local wind speed and the ideal wind speed, quantifying the degree of external disturbance currently affecting the air curtain barrier. The morphological deviation of the air curtain barrier can be understood as the difference between the actual shape of the air curtain barrier and the preset ideal shape. This morphological deviation is not directly measured but indirectly calculated through wind speed deviation. For example, when the local wind speed deviates from the ideal wind speed, the shape, thickness, or coverage area of ​​the air curtain barrier may change; this change is considered a morphological deviation. The purpose of calculating the morphological deviation is to transform the abstract wind speed difference into a quantitative indicator of its impact on the physical shape of the air curtain barrier, enabling subsequent precise adjustments. In practical applications, the coordinated adjustment of the fan power and the angle of the airflow guide vanes in the air curtain generating device refers to simultaneously and coordinately adjusting the fan output power and the angle of the airflow guide vanes based on the calculated morphological deviation. The power adjustment of the fan directly affects the airflow intensity and velocity of the air curtain barrier, while the angle adjustment of the airflow guide vanes affects the direction and distribution of the airflow. Through coordinated adjustment, morphological deviations can be compensated for more flexibly and precisely, allowing the air curtain barrier to quickly return to its ideal shape.

[0059] This application achieves refined perception of the air curtain barrier's morphology by introducing calculations of wind speed and shape deviations. When the external wind speed changes, the wind speed sensor can capture local wind speed fluctuations in real time and compare them with a preset ideal wind speed to determine the wind speed deviation. Based on this wind speed deviation, potential shape deviations of the air curtain barrier can be further calculated, such as the barrier becoming thinner, bent, or developing gaps. It is precisely this quantification of shape deviations that allows the system to make targeted adjustments. By coordinating the adjustment of the fan power and the angle of the airflow guide vanes, a synergistic effect can be achieved. On the one hand, adjusting the fan power changes the overall intensity of the airflow; on the other hand, adjusting the angle of the airflow guide vanes optimizes the distribution and direction of the airflow, thereby effectively counteracting the impact of external wind on the air curtain barrier's morphology and restoring it to the expected blocking state.

[0060] By employing the aforementioned solution, this application overcomes the problem of insufficient stability in the shape of air curtain barriers in traditional solutions. Through precise calculation of wind speed and shape deviations, the system can accurately and in real-time grasp the actual state of the air curtain barrier and make refined, coordinated adjustments accordingly. This adjustment method not only improves the adaptability of the air curtain barrier to environmental changes, ensuring a stable blocking effect under different wind speed conditions, but also avoids energy waste or reduced insect-repelling effectiveness caused by excessive or insufficient adjustment. Therefore, the insect-repelling performance of the air curtain barrier is significantly improved, ensuring hygiene and safety in the beer dispenser area and providing users with a superior beer-making experience.

[0061] Furthermore, the steps for adjusting the power of the fan and the angle of the airflow guide vanes in the air curtain generator based on morphological deviation include: Calculate the Euclidean norm of the morphological deviation as the overall deformation index; The overall deformation index is input into the preset PID controller to calculate the power correction amount used to adjust the fan and the angle correction amount used to adjust the airflow guide vanes; Based on the power correction and angle correction, the power of the fan and the angle of the airflow guide vanes in the air curtain generator are adjusted in a coordinated manner.

[0062] Specifically, the Euclidean norm, a commonly used mathematical tool for measuring the length or magnitude of multidimensional vectors, is used here to quantify multiple local morphological deviations into a single, comprehensive overall deformation index. This index effectively reflects the combined impact of the degree of deformation of the air curtain barrier at different locations or directions, thus providing a more representative measure of overall deformation.

[0063] The overall deformation index is then input to a preset PID controller. A PID controller, or Proportional-Integral-Derivative (PID) controller, is a feedback control algorithm widely used in industrial control. It calculates the control output by combining proportional, integral, and derivative terms. Specifically, the proportional term adjusts according to the current error magnitude, the integral term eliminates steady-state error, and the derivative term predicts the error's trend, thereby improving the system's response speed and stability. Based on the input overall deformation index, the PID controller calculates the power correction for adjusting the fan and the angle correction for adjusting the airflow guide vanes. These corrections are outputs optimized by the PID algorithm, designed to precisely correct the deformation of the air curtain barrier.

[0064] This application quantifies the overall deformation of the air curtain barrier by introducing the Euclidean norm, integrating multi-dimensional morphological deviations into a single, physically meaningful overall deformation index. This allows the control system to more comprehensively understand the actual state of the air curtain barrier. Furthermore, this overall deformation index is input into a PID controller. Leveraging the advantages of PID controllers in handling dynamic systems and eliminating errors, the optimal correction amounts for fan power and airflow guide vanes can be accurately calculated based on current deformation, historical deformation accumulation, and deformation trends. This achieves refined and adaptive control of the air curtain barrier morphology, effectively overcoming the potential inaccuracies and response hysteresis problems of traditional simple adjustment methods.

[0065] The above technical solutions significantly improve the accuracy and stability of air curtain barrier morphology control. By comprehensively quantifying morphological deviations using the Euclidean norm, misjudgments or under-adjustment that might result from localized deviations are avoided. The application of a PID controller enables the system to respond quickly and smoothly to external disturbances such as sudden wind changes, effectively suppressing fluctuations and deformations of the air curtain barrier, thus ensuring that the barrier maintains optimal mosquito-blocking performance. Furthermore, this refined adjustment helps optimize energy consumption, avoids unnecessary over-adjustment, and extends equipment lifespan.

[0066] Furthermore, the method also includes: When the user's action of ending the dispensing action is detected, an end signal is generated. Based on the end signal, after a first preset time delay, the control air curtain generating device is stopped. The action of ending the dispensing action is detected by detecting the reset action of the handle by a sensor installed in the handle of the beer dispenser or by detecting the movement of the cup or the user's hand away by a non-contact distance sensor installed in the dispensing area.

[0067] Specifically, ending the dispensing action refers to the user completing the beer dispensing process and preparing to move the glass away from the dispensing area or returning the dispensing nozzle handle to its initial position. Detecting this action is crucial for the intelligent start and stop of the air curtain barrier. There are two or more ways to detect the end of the dispensing action. One method is to detect the handle's reset action using a sensor located within the dispensing nozzle handle. For example, when the user releases the handle, and it returns to its initial position under spring pressure, sensors such as microswitches or Hall effect sensors will detect this change and identify it as the end of the dispensing action. Another method is to detect the movement of the glass or the user's hand away from the dispensing area using a non-contact distance sensor located in the dispensing area. For example, when the user moves the glass away from under the dispensing nozzle, or removes their hand from the dispensing area, distance sensors such as infrared sensors or ultrasonic sensors will detect an increase in the distance between the object and the dispensing nozzle and determine that the dispensing action has ended. When either of these ending actions is detected, an end signal is generated. This end signal indicates that the air curtain barrier is about to stop operating.

[0068] Upon receiving the termination signal, the air curtain generator does not immediately stop working, but rather delays for a first preset time before stopping. The first preset time can be set according to actual needs, for example, it can be set to 2 to 5 seconds, ensuring that the air curtain barrier continues for a period of time after the user has completely removed the glass or hand, effectively blocking mosquitoes that may take the opportunity to enter and providing more comprehensive protection.

[0069] This application effectively solves the problem of unclear or unreasonable stopping timing of the air curtain barrier in the basic solution by introducing a detection mechanism for the user's completion of the dispensing action and combining it with a delayed stopping strategy. Specifically, when the user completes the dispensing operation, whether through the reset detection of the sensor inside the dispensing gun handle or the detection of the cup or hand moving away by the non-contact distance sensor in the dispensing area, the user's intention to stop can be identified in a timely and accurate manner. The resulting end signal provides a clear instruction for the air curtain generator to stop. In addition, after receiving the end signal, the air curtain generator does not stop immediately, but introduces a first preset time delay. This delay mechanism allows the air curtain barrier to continue to maintain for a short period of time after the user removes the cup, thus providing continuous insect protection for the dispensing area. This effectively avoids the possibility of insects taking advantage of the gap due to the air curtain barrier stopping too early, ensuring the hygiene and safety of the beer. At the same time, controlling the stopping timing by accurately detecting the user's actions also avoids the energy waste caused by the air curtain barrier running unnecessarily for a long time.

[0070] Through the above-described solution, this application enables the intelligent and efficient stopping of the air curtain barrier, avoiding unnecessary power consumption. Simultaneously, by providing a delayed protection period after the user finishes dispensing the beer, it effectively compensates for the potential shortcomings of the basic solution in terms of protective continuity, further enhancing the barrier effect against mosquitoes and ensuring the hygiene and safety of the beer throughout the dispensing process and for a short period afterward.

[0071] Furthermore, after the air curtain generating device forms an air curtain barrier in the beer dispensing area of ​​the beer machine, it includes: If the user's action to end the wine dispensing is not detected after waiting for the second preset time, a maintenance prompt message will be generated.

[0072] Specifically, the second preset time refers to a pre-set time length used to define the maximum time from the formation of the air curtain barrier to the time the system expects the user to complete the dispensing action and leave the dispensing area. This time can be set empirically based on factors such as the actual application scenario, the dispensing speed of the beer machine, and the average dispensing time of the user. For example, it can be set to 10 seconds, 20 seconds, or 30 seconds to provide a reasonable waiting window to determine whether the user has completed the operation.

[0073] The failure to detect the user's action to end the dispensing process can be understood as the absence of any signal indicating that the user has completed the dispensing operation or left the dispensing area by the end of the second preset time. This may include the failure to detect the reset action of the dispensing gun handle, or the failure to detect the movement of the glass or the user's hand away from the dispensing area.

[0074] In practical applications, after an abnormal situation is identified, a warning is issued to the user or maintenance personnel in some way. For example, this could be a text message displayed on the beer dispenser screen asking for a check of the dispensing area or a system malfunction, and requesting that maintenance personnel be contacted. Alternatively, it could be an audible and visual alarm, or the alarm information could be sent to a remote monitoring system via the network to promptly remind relevant personnel to pay attention to and address potential problems, preventing the equipment from running idle for extended periods or malfunctioning.

[0075] This application effectively solves the problems of equipment idling and resource waste that may occur in the basic solution by introducing a monitoring mechanism to detect when the user finishes dispensing beer and setting a reasonable waiting time. Once the air curtain barrier is activated, it continuously monitors whether the user has completed the dispensing operation. If no signal indicating the end of dispensing is detected within a preset second time period, this is considered an abnormal state. At this time, a maintenance prompt message is actively generated, prompting relevant personnel to intervene promptly and check the beer machine's working status or the user's operation. This mechanism ensures that the air curtain generating device operates only when necessary, avoiding prolonged ineffective operation due to user interruption or forgetfulness.

[0076] Through the above-described solution, this application significantly improves the intelligence level and operational efficiency of the beer machine control system. By promptly detecting and alerting users or the system to potential anomalies, it effectively prevents the air curtain generator from operating for extended periods without actual demand, thereby saving energy consumption and extending the equipment's lifespan. Furthermore, this maintenance alert mechanism helps improve the user experience, reduces inconvenience caused by equipment malfunctions, and provides maintenance personnel with a basis for quickly locating and resolving problems, further ensuring the stable and reliable operation of the beer machine.

[0077] Secondly, see Figure 2 This application also discloses an automatic mosquito-repellent beer dispenser based on an air curtain barrier, including an air curtain generating device 200 disposed above the beer dispenser's outlet. The air curtain generating device 200 includes: The motion detection and signal generation module 201 is used to generate a start signal when the user's action of pouring wine is detected; The air curtain generating and regulating module 202 is used to control the air curtain generating device to form an air curtain barrier in the beer dispensing area of ​​the beer machine according to the start signal, so as to block mosquitoes. It is also used to acquire environmental parameters and adjust the strength and / or shape of the air curtain barrier based on the environmental parameters.

[0078] This application applies air curtain barrier technology to beer dispensers and integrates intelligent motion detection and environmental adaptive adjustment functions, aiming to address the shortcomings of traditional mosquito repellent solutions in terms of food hygiene, ease of operation, and protective effect. The beer dispenser can automatically sense the user's dispensing action and promptly activate the air curtain barrier, providing dynamic and effective physical isolation of the beer dispensing area without introducing chemicals or affecting the operation process. Simultaneously, by monitoring environmental parameters in real time and intelligently adjusting the strength and shape of the air curtain barrier, optimal mosquito repellency is maintained under different external conditions, thereby improving user experience, ensuring food safety, and optimizing energy efficiency. By setting up a motion detection and signal generation module 201, the user's dispensing action can be automatically sensed and a start signal generated, thereby driving the air curtain generation and adjustment module 202 to form an invisible, dynamic air curtain barrier in the beer dispenser area. This physical isolation method avoids the introduction of chemicals, ensuring the purity of the beer and food safety. Furthermore, since the air curtain barrier is automatically generated and deactivated, no additional operation is required from the user, greatly improving ease of use. Furthermore, the beer dispenser acquires environmental parameters through the air curtain generation and adjustment module 201 and adjusts the strength and / or shape of the air curtain barrier accordingly, allowing the mosquito-repelling effect to be optimized based on actual environmental conditions. For example, when mosquito activity is high or there is external wind interference, the air curtain barrier can automatically adjust to provide stronger protection, ensuring efficient mosquito-repelling capabilities in various complex environments. This intelligent adaptive adjustment mechanism is not available in existing technologies; it not only improves the effectiveness of protection but also optimizes energy consumption, avoiding unnecessary waste. Therefore, the beer dispenser of this application significantly improves user experience and operational efficiency while ensuring food hygiene, providing an innovative and efficient solution for mosquito protection in food contact areas such as beer dispensers.

[0079] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
