Description

Technical Field

[0001] The present invention relates to the technical field of car washers, and in particular to a double-layer filtering system for a self-service car washer and a control method thereof. Background Art

[0002] A self-service car wash is a convenient car washing device that allows users to operate the car washing process by themselves without human assistance. This type of equipment is usually located in gas stations, shopping malls, community parking lots, etc., so that car owners can quickly clean their vehicles when needed. The basic principle of a self-service car wash is that the user operates the control panel, selects the car washing mode, and then the machine completes the car washing process through tools such as high-pressure water guns, detergent sprays, and brushes.

[0003] In the prior art, a single-layer filtration system may not be able to effectively filter out all dust and impurities, resulting in unstable quality of the car wash liquid and affecting the car washing effect. This is because the car washing machine requires a certain high pressure to spray the cleaning liquid on the surface of the vehicle. Since the filtration system cannot effectively remove impurities, the cleaning liquid may contain a large amount of dust and particles. These particles may cause scratches on the car paint under the action of water pressure, affecting the car washing effect and the appearance of the vehicle. Secondly, if the cleaning liquid undergoes multiple filtrations each time, it is difficult to ensure the normal supply of the cleaning liquid or the energy consumption is too high, which increases the operating cost and maintenance workload. Therefore, the prior art has defects and needs to be improved. Summary of the invention

[0004] In order to solve one or several problems in the prior art, the main purpose of the present invention is to provide a double-layer filtration system for a self-service car washing machine and a control method thereof.

[0015] When the cleaning agent in the first filter part does not meet the output condition, the connecting part is controlled to move from the first position to the second position, so that the first filter part is connected with the second filter part, and the cleaning agent that does not meet the output condition moves from the first filter part to the second filter part;

[0016] Whether the cleaning liquid in the second filter part meets the output condition is detected in real time, and when the cleaning liquid in the second filter part meets the output condition, the cleaning liquid is allowed to be output from the second outlet of the communication part.

[0040] like Figure 1 and Figure 3As shown, the embodiment of the present application provides a double-layer filtering system for a self-service car washing machine, including a frame 1, a first filter part 2, a second filter part 3, a connecting part 4 and a control part 5, wherein the first filter part 2 and the second filter part 3 are respectively arranged on the frame 1, the connecting part 4 is arranged between the first filter part 2 and the second filter part 3, and the control part 5 is arranged on one side of the first filter part 2; the control part 5 is used to detect whether the cleaning liquid filtered by the first filter part 2 meets the output condition, when the cleaning liquid meets the output condition, the cleaning liquid is output from the first outlet 40 of the connecting part 4; when the cleaning liquid does not meet the output condition, the connecting part 4 is controlled to move from the first position to the second position, the first filter part 2 is connected with the second filter part 3, the cleaning liquid reaches the second filter part 3 from the first filter part 2, and the cleaning liquid is output from the second outlet 41 of the connecting part 4. In this embodiment, the frame 1 is used as the basic structure of the self-service car washing machine, providing a stable support platform to place and fix all car washing equipment. The first filter part 2 is located on the frame 1, and is used to preliminarily filter impurities in the cleaning liquid. It may include a filter, filter material or other physical isolation means. Particles and impurities in the cleaning liquid are intercepted by physical means (such as a filter). The service life of the cleaning liquid is extended, the impact on the car washing effect is reduced, and the internal part of the equipment is protected from pollution. The second filter part 3 is also located on the frame 1, after the first filter part 2, and is used to further filter the smaller particles in the cleaning liquid. A finer filter or activated carbon and other materials may be used to further remove smaller particles and harmful substances. The quality of the cleaning liquid is further improved to ensure that the discharged liquid does not pollute the environment. The connecting part 4 is located between the first filter part 2 and the second filter part 3, allowing the cleaning liquid to flow between the two. A movable connection is designed, such as a valve or a movable isolation plate, which switches positions according to the instructions of the control part 5. The cleaning liquid that does not meet the output conditions is allowed to flow back to the first filter part 2 for re-filtration to ensure the quality of the output liquid. The control part 5 usually includes a sensor and a microprocessor, which is used to monitor the quality of the cleaning liquid and adjust the state of the connecting part 4 as needed. The sensor is used to detect the cleanliness of the cleaning liquid, and the data is sent to the microprocessor for analysis, and the action of the connecting part 4 is automatically controlled according to the preset threshold. Automated control ensures the quality of cleaning fluid during the car wash process, reduces the need for manual operation, and improves car wash efficiency and user experience.

[0041] Specifically, by setting up a double-layer filtration system, dust and impurities in the cleaning liquid can be filtered out more effectively. The first layer of filtration can remove larger particles, while the second layer of filtration can capture smaller particles and harmful substances. In this way, the quality of the cleaning liquid output to the high-pressure spray is steadily improved, effectively reducing the potential risk of scratches on the vehicle surface and maintaining the finish of the vehicle appearance. The control unit 5 can intelligently monitor the quality of the cleaning liquid and dynamically adjust the position of the connecting part 4 to ensure that while ensuring the quality of the cleaning liquid, the life of the filtration system will not be excessively consumed or unnecessary energy consumption will be increased. This balance ensures that the cleaning liquid can maintain the continuity and stability of supply while meeting the filtration requirements. Since the double-layer filtration system can effectively filter impurities, the frequency of cleaning liquid replacement is reduced, thereby reducing operating costs. At the same time, due to the reasonable design of the filtration system, the possibility of failures such as filter blockage is reduced, and the maintenance workload and maintenance costs are reduced. High-quality cleaning effects can improve user satisfaction with self-service car wash services, thereby attracting more users to use them and improving the attractiveness and profitability of the equipment.

[0042] like Figure 2 and Figure 3As shown, further, the connecting part 4 includes a main body, a first outlet 40 and a second outlet 41, the first outlet 40 and the second outlet 41 are respectively arranged on the first side and the second side of the main body, the first outlet 40 includes a first switching channel 401 and a second switching channel 402 respectively arranged on the main body, and the second outlet 41 includes a third switching channel; when the main body is in the first position, the first switching channel 401 of the first outlet 40 is in a conducting state; when the main body moves from the first position to the second position, the second switching channel 402 is connected to the third switching channel. In this embodiment, the main body is the basic part of the connecting part 4, which connects the first outlet 40 and the second outlet 41. The design of the main body should ensure sufficient strength and durability to withstand the pressure and friction in daily use. The first outlet 40 and the second outlet 41 are respectively arranged on the first side and the second side of the main body, allowing the cleaning liquid to flow between the double-layer filtration system. Their position design ensures that the cleaning liquid can pass through the first and second layers of filters smoothly, while facilitating maintenance and replacement of filter elements. The first switching channel 401 and the second switching channel 402 are the key parts for controlling the flow of the cleaning liquid. In the first position, the first switching channel 401 is turned on, and the cleaning liquid can flow from the first layer filter to the second layer filter. When the main body moves to the second position, the second switching channel 402 and the third switching channel are turned on, allowing the cleaning liquid to flow out from the second layer filter to complete the filtering process. The conduction state of the switching channel is controlled by a physical or electronic control mechanism, such as a solenoid valve, a mechanical switch, etc. When the main body is in the first position, the first switching channel 401 is opened, and the cleaning liquid flows through the first layer filter. When the main body moves to the second position, the first switching channel 401 is closed, the second switching channel 402 and the third switching channel are opened, and the cleaning liquid flows through the second layer filter and then flows out. By switching the different states of the channel, the flow path of the cleaning liquid can be flexibly controlled to achieve effective double-layer filtration. The second layer filter plays the role of the last filter before the cleaning liquid flows out, further removing impurities and improving the quality of the cleaning liquid. Due to the design of the switching channel, the filter can be replaced and cleaned more conveniently, reducing the maintenance workload and time. By controlling the flow path of the cleaning liquid, it can be ensured that the vehicle surface is thoroughly cleaned while reducing potential damage to the paint.

[0043] like Figure 1As shown, further, the control unit 5 includes a detection component, which is respectively arranged at the output end of the first filter unit 2 and the second filter unit 3, and the detection component is used to detect whether the cleaning liquid output by the first filter unit 2 and / or the second filter unit 3 meets the preset filtering effect. In this embodiment, the detection component is used to monitor whether the cleaning liquid output by the first filter unit 2 and / or the second filter unit 3 achieves the preset filtering effect. This involves detecting the particle size, quantity or overall clarity of the cleaning liquid in the cleaning liquid. Physical detection: Physical methods such as microporous membranes, optical sensors, and particle counters can be used to detect particulate matter in the cleaning liquid. Chemical detection: If it is necessary to detect the chemical composition of the cleaning liquid, chemical sensors or pH meters and other equipment can be used. Electrical detection: Conductivity sensors are used to detect the ion content in the cleaning liquid to evaluate the filtering effect. The detection components are respectively arranged at the output ends of the first filter unit 2 and the second filter unit 3, so that the quality detection can be performed as soon as the cleaning liquid flows out of the filter to ensure that the cleaning liquid achieves the expected filtering effect. By arranging the detection component at the output end, the filtering effect of the cleaning liquid can be monitored in real time and problems can be discovered in time. If the cleaning liquid does not meet the preset filtering effect, the detection component can send a signal to trigger the control unit 5 to take measures, such as adjusting the working state of the filter or re-filtering, to ensure that the cleaning liquid output to the high-pressure spray is high-quality and safe. High-quality cleaning liquid can improve user satisfaction with the self-service car wash service, thereby attracting more users to use it and improving the attractiveness and profitability of the equipment. Through real-time monitoring, problems can be dealt with in a timely manner when they occur, reducing potential damage to the vehicle and reducing maintenance costs caused by poor filtering effects.

[0044] like Figure 1As shown, further, the control unit 5 also includes a pressure regulating component 50, which is respectively arranged on the first filter part 2 and the second filter part 3, and the pressure regulating component 50 is used to detect the pressure value of the cleaning liquid in the first filter part 2 and the second filter part 3, and adjust the pressure balance inside the first filter part 2 and the second filter part 3. In this embodiment, a pressure sensor or a pressure gauge is used to detect the pressure value of the cleaning liquid in the first filter part 2 and the second filter part 3. The pressure of the cleaning liquid is adjusted by controlling a valve, a pump or other fluid power device to ensure that the pressure in the two filters is balanced. The pressure regulating component 50 is respectively arranged on the first filter part 2 and the second filter part 3, so that the pressure of the cleaning liquid inside the filter can be directly adjusted to ensure that the flow of the cleaning liquid between the two filters will not affect the filtering effect due to the pressure difference. Through the pressure regulating component 50, it can be ensured that the pressure of the cleaning liquid inside the first filter part 2 and the second filter part 3 is balanced, avoiding the unstable flow of the cleaning liquid caused by the pressure difference, thereby ensuring the filtering effect. Pressure balance helps the cleaning liquid to flow evenly between the two filters, improving the filtering efficiency and cleaning effect. Avoiding excessive load work of the filter due to pressure difference can extend the service life of the filter. By maintaining pressure balance, maintenance costs due to filter damage or performance degradation can be reduced.

[0045] like Figure 2 As shown, further, the first outlet 40 is arranged on a side of the main body close to the mounting surface, and the second outlet 41 is arranged on a side of the main body away from the mounting surface. By using the principle of fluid dynamics, when the cleaning of the first filter part 2 meets the conditions for outputting the cleaning liquid, the cleaning liquid can be quickly output from the first outlet 40.

[0046] like Figure 4 As shown, a double-layer filtration control method for a self-service car washing machine, the method comprising:

[0047] S1, real-time acquisition of the trigger instruction sent by the control unit 5;

[0048] S2, controlling the first filter unit 2 to filter the cleaning liquid according to the trigger instruction, and detecting in real time whether the cleaning liquid passing through the first filter unit 2 meets the output condition;

[0049] S3, when the cleaning agent in the first filter part 2 does not meet the output condition, the connecting part 4 is controlled to move from the first position to the second position, so that the first filter part 2 is connected with the second filter part 3, and the cleaning agent that does not meet the output condition moves from the first filter part 2 to the second filter part 3;

[0050] S4. Real-time detection of whether the cleaning liquid in the second filter part 3 meets the output condition. When the cleaning liquid in the second filter part 3 meets the output condition, the cleaning liquid is allowed to be output from the second outlet 41 of the connecting part 4.

[0051] As described above, the trigger instruction sent by the control unit 5 is transmitted to the receiving device in real time through a wired or wireless communication method. The receiving device needs to be able to parse and identify these trigger instructions in order to perform the next step of operation. According to the trigger instruction, the first filter unit 2 is controlled to filter the cleaning liquid, and the filtered cleaning liquid is detected in real time whether it meets the output conditions. The first filter unit 2 filters the cleaning liquid by physical or chemical means to remove impurities and pollutants. A sensor or an analytical instrument is used to detect the quality of the cleaning liquid in real time to determine whether it meets the output standard. When the cleaning liquid of the first filter unit 2 does not meet the output conditions, the connecting part 4 is controlled to move from the first position to the second position, so that the first filter unit 2 is connected to the second filter unit 3, and the cleaning agent that does not meet the output conditions moves from the first filter unit 2 to the second filter unit 3. The connecting part 4 realizes the movement from the first position to the second position by a mechanical device (such as a servo motor, a pneumatic or hydraulic system). By moving the connecting part 4, the flow path of the cleaning liquid is changed so that it flows from the first filter unit 2 to the second filter unit 3. Real-time detection of whether the cleaning liquid of the second filter unit 3 meets the output conditions. A detection device similar to that of the first filter unit 2 is used to detect the quality of the cleaning liquid in the second filter unit 3. When the cleaning liquid in the second filter unit 3 meets the output conditions, the cleaning liquid is allowed to be output from the second outlet 41 of the connecting part 4. By controlling the switch of the valve, the cleaning liquid that meets the conditions can flow out from the second outlet 41. Through double-layer filtration, the filtration efficiency of the cleaning liquid can be improved to ensure that the output is high-quality cleaning liquid. Users use high-quality cleaning liquid that has been double-layer filtered, which can better clean the vehicle and improve user satisfaction. By moving the connecting part 4, it is possible to flexibly switch between the first filter unit 2 and the second filter unit 3, which improves the adaptability and flexibility of the system. When the cleaning liquid in the first filter unit 2 does not meet the output conditions, it can be moved to the second filter unit 3 through the connecting part 4 to continue filtering, reducing the waste of cleaning liquid and thus reducing maintenance costs.

[0052] In one embodiment, after the step of controlling the connecting portion 4 to move from the first position to the second position, the method comprises:

[0053] Acquire the pressure data of the first filter part 2 and the second filter part 3 in real time;

[0054] Determining whether the pressure data satisfies the condition for the cleaning liquid in the first filter part 2 to move to the second filter part 3;

[0055] When the pressure data part does not satisfy the condition for the cleaning liquid of the first filter part 2 to move to the second filter part 3, an adjustment instruction is sent to the pressure adjustment component 50, and the pressure adjustment component 50 adjusts the first filter part 2 and the second filter part 3 according to the threshold pressure value.

[0056] As described above, a pressure sensor is installed in each of the first filter part 2 and the second filter part 3 for real-time monitoring and collecting the pressure data of the filter part. Real-time monitoring can ensure that the pressure change of the filter part is understood in time, which is convenient for the next step of judgment and adjustment. By comparing the pressure data obtained in real time with the preset pressure threshold, it is judged whether the cleaning liquid of the first filter part 2 can be moved to the second filter part 3. This step can ensure that the ineffective movement of the cleaning liquid is avoided when the pressure condition is not met, and improve the system operation efficiency. When the pressure data does not meet the conditions, the control system will send instructions to the pressure regulating component 50, which may include a pressure control valve, etc., for adjusting the pressure. The adjustment instruction can ensure that the system can respond quickly when needed, and optimize the flow of the cleaning liquid by adjusting the pressure to the preset threshold. The pressure regulating component 50 will adjust the pressure of the first filter part 2 and the second filter part 3 according to the preset pressure threshold, so that it reaches a state suitable for the flow of the cleaning liquid. Through precise pressure regulation, it can be ensured that the cleaning liquid flows smoothly between the two filter parts, and the stability and reliability of the entire filtering process are improved.

[0057] In one embodiment, after the step of detecting in real time whether the cleaning liquid in the second filter part 3 meets the output condition, the method includes:

[0058] When the cleaning liquid in the second filter unit 3 does not meet the output condition, obtaining impurity data and pressure data of the cleaning liquid in the second filter unit 3;

[0059] Analyze the reasons why the cleaning liquid of the second filter part 3 does not meet the output requirements according to the impurity data of the cleaning liquid and the pressure data of the cleaning liquid, wherein the reasons include water pressure reasons, failure of the first filter part 2 and / or the second filter part 3;

[0060] A solution strategy is generated according to the reasons for the unsatisfactory output, and an early warning message is sent to the user end.

[0061] As mentioned above, an impurity detection sensor and a pressure sensor are installed in the second filter 3 to monitor and collect the impurity content and pressure of the cleaning liquid in real time. By obtaining these key data, the system can comprehensively evaluate the condition of the cleaning liquid and provide data support for further analysis of the cause. The system will use an algorithm to analyze the collected impurity data and pressure data to determine the reason why the cleaning liquid does not meet the output conditions, such as whether the water pressure is insufficient, or whether there is a fault in the first filter 2 or the second filter 3. By deeply analyzing the cause, the system can locate the problem and provide a basis for formulating a solution strategy. Based on the analysis results, the system will automatically generate targeted solution strategies, such as increasing water pressure, repairing filter failures, etc. Automatically generating a solution strategy can improve the efficiency of problem solving and reduce the need for manual intervention. Through the early warning system, the generated solution strategy is sent to the user in the form of an information prompt, so that the user can understand the system status in a timely manner and make corresponding treatments. The early warning information can help users find problems in a timely manner and take measures to avoid potential equipment damage or production interruptions.

[0062] In one embodiment, after the step of analyzing the reason why the cleaning liquid of the second filter part 3 does not meet the output requirements according to the impurity data of the cleaning liquid and the pressure data of the cleaning liquid, the method includes:

[0063] When the reason why the cleaning liquid fails to output is due to water pressure, the maximum water pressure tolerance of the first filter part 2 and the second filter part 3 is analyzed;

[0064] Input the pressure data and impurity data into a preset decision model, calculate the water pressure value that needs to be adjusted according to the current impurity data through the decision model, and determine whether the water pressure value is within the range of the maximum water pressure tolerance value;

[0065] If the water pressure value is within the range of the maximum water pressure tolerance value, the flow rate parameter of the cleaning liquid input end is adjusted based on the water pressure value so that the water pressure of the cleaning liquid reaches the target water pressure value.

[0066] As described above, the technical parameters and operating data of the equipment are consulted to determine the maximum water pressure value that the first filter part 2 and the second filter part 3 can withstand, ensuring that these safety limits are not exceeded when adjusting the water pressure. This step can ensure that the system will not cause equipment damage when adjusting the water pressure, and ensure the safe and stable operation of the system. The decision model may be a model based on a machine learning algorithm, which uses the input pressure data and impurity data to calculate the water pressure value that needs to be adjusted so that the water pressure of the cleaning liquid reaches the target value. Through the calculation of the decision model, the water pressure can be accurately adjusted to improve the stability and efficiency of the output of the cleaning liquid. The system will calculate the required water pressure adjustment value through the decision model based on the current impurity data and the target water pressure value, and compare it with the maximum tolerance value of the two filter parts. This step can ensure that the adjusted water pressure can meet the needs of the output of the cleaning liquid without exceeding the safety range of the equipment. By adjusting the flow rate parameter of the cleaning liquid input end, the rate at which the cleaning liquid flows into the first filter part 2 and the second filter part 3 can be controlled, thereby affecting the water pressure of the cleaning liquid. This adjustment method can quickly and accurately adjust the water pressure of the cleaning liquid to reach the target value, thereby optimizing the entire filtration process.

[0067] It is worth mentioning that the reason for setting the water pressure value through the model is that the output conditions of the filtration system are affected by many factors, including the flow rate of the cleaning liquid, the efficiency of the filter, the performance of the equipment, etc. The relationship between these factors may be very complex and may change over time. Therefore, a model that can adapt to these changes is needed to calculate the optimal water pressure value. The filtration process of the cleaning liquid may change due to factors such as the length of working time, the aging of the filter medium, and the change of the input liquid. The model can adjust the calculation parameters in real time to adapt to these changes and ensure that the output conditions are met. The model can accurately calculate the required water pressure value based on the specific filtering conditions and target output requirements. This is more accurate than relying on experience or manual adjustment, and can avoid equipment damage or reduced filtration effect caused by excessive or low water pressure. By calculating the water pressure value through the model, the result can be quickly obtained, so as to quickly adjust the input parameters of the system and improve the response speed and operation efficiency of the system. For example, suppose that after a filtration system has been running for a long time, the efficiency of the first filter part 2 decreases, resulting in the impurity content in the cleaning liquid exceeding the processing capacity of the second filter part 3. At this time, if you only rely on increasing the water pressure to increase the flow rate of the cleaning liquid, the filter may be damaged or the system may be unstable due to excessive water pressure. Through model calculation, the system can comprehensively consider multiple factors such as the current efficiency of the filter, the flow rate of the cleaning liquid, the safety limit of the system, etc., and calculate the appropriate water pressure adjustment value. In this way, the flow rate of the cleaning liquid can be increased to remove more impurities, and the maximum water pressure of the filter can be avoided to ensure the stable operation of the system.
