The control method of the automatic drain valve is basically to adjust the drainage time by setting the time parameters in the controller. Some products are also controlled according to the braking time, such as how many times the foot brake is stepped on, or how long the air pump works to drain water. However, no matter which of the above control strategies is used, it is impossible to determine whether there is water accumulation in the air tank and needs to be drained; and the automatic drain valve cannot determine whether there is water accumulation in the air tank in winter and needs to be heated.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0064] In the related technology, the braking systems of most commercial vehicles in the world use pneumatic brakes. Its working principle is that the air is compressed by the air pump, stored in a high-pressure container, and then transported to the pneumatic brake device through a pipeline for use. Compared with hydraulic brakes and electric brakes, its structure is simple and reliable, and the cost is relatively low. However, pneumatic brakes also have their own unique disadvantages, that is, the compressed air pumped out by the air pump often contains a large amount of water and some oil impurities. Even if it is filtered by filtering devices such as condensers and dryers, it is still impossible to completely remove the residual water, resulting in the accumulation of oil-water mixture in the air tank and entering various functional components through the brake pipeline, causing the brake valve to rust and damage, or freezing in winter and unable to work normally, etc., seriously affecting driving safety and vehicle use. Usually, the solution is to install a drain valve at the bottom of the air tank to drain the water, and the drain valve is divided into two types: manual drain valve and automatic drain valve.

[0065] The automatic drain valve controls the electric drain valve installed at the bottom of the air tank of the vehicle's brake system through a controller to drain water. The control method of the automatic drain valve is basically to adjust the drainage time by setting the time parameters in the controller. Some products are also controlled according to the braking time, such as how many times the foot brake is pressed, or how long the air pump works to drain water. However, no matter which of the above control strategies is used, it is impossible to determine whether there is water accumulation in the air tank and needs to be drained; and the automatic drain valve cannot determine whether there is water accumulation in the air tank in winter and ice needs to be heated.

[0066] The above shortcomings may lead to the following problems: for example, in a high humidity environment, the automatic drain valve cannot drain the air when the air tank needs to be drained at short intervals, or in a low humidity environment, the air tank is frequently drained when it does not need to be drained, resulting in a drop in air pressure and a longer load time for the air pump. Or in winter, heating the air tank when it is not frozen and does not need to be heated, resulting in a waste of vehicle energy.

[0067] In particular, for new energy vehicles, how to accurately control energy utilization efficiency within limited vehicle range has always been a pain point in vehicle control. Therefore, how to improve its automatic drainage system to make it more accurate in drainage and heating can effectively improve the energy utilization efficiency of the braking system and increase the range of new energy vehicles.

[0068] like Figure 1 As shown, in order to solve the above technical problems, the present application also provides a drainage valve control method, which includes the following steps:

[0069] Step S100: obtaining an operation instruction of the drain valve 10, wherein the drain valve 10 is provided in the gas cylinder, and the drain valve 10 comprises a heating device 100 and a drain device, and the operation instruction is used to determine a target melting strategy for the heating device 100 to melt ice in the gas cylinder and a target discharge strategy for the drain device to discharge the accumulated water in the gas cylinder;

[0070] In these embodiments, the working modes of the heating device 100 and the drainage device are dynamically adjusted according to the internal state of the gas cylinder (such as temperature, humidity, water accumulation depth, etc.) detected in real time.

[0071] Initializing the system: When the system starts, the controller is initialized and ready to receive data from the sensors.

[0072] Collect environmental characteristic data: Use a variety of sensors (such as temperature sensors, humidity sensors, and liquid level sensors) to monitor the environmental characteristic data in the gas cylinder in real time. For example, the temperature sensor is used to detect the temperature inside the gas cylinder to determine whether there is a risk of freezing. The humidity sensor is used to assess the humidity level in the gas cylinder and predict the possibility of water accumulation. The liquid level sensor is used to measure the depth of water accumulation in the gas cylinder to determine whether drainage is required. Of course, the dielectric constant can also be detected in the following text to determine the state of water accumulation in the gas cylinder (whether there is water accumulation, whether it is frozen, the depth of water accumulation, etc.), that is, the environmental characteristic data.

[0073] Setting operation instructions: According to the collected environmental characteristic data, the operation instructions are set or adjusted. These parameters are used to determine the target melting strategy of the heating device 100 and the target discharge strategy of the drainage device. The target melting strategy defines the conditions under which the heating device 100 is started and the time and intensity of heating. The target discharge strategy defines the conditions under which the drainage device is started and the time interval and frequency of drainage.

[0074] Storing and transmitting data: The collected data and set operation instructions are stored in a local or cloud database for subsequent analysis and optimization. The data can be transmitted to the central control system or other monitoring equipment through the wireless communication module.

[0075] Step S200: Based on the operation instruction, control the operation of the heating device 100 and the drainage device.

[0076] In these embodiments, data analysis and decision making: the controller performs real-time analysis on the collected data to determine the current state of the gas cylinder. If it is detected that the accumulated water exceeds a preset threshold, the drainage device is activated to drain the water. If ice is detected and there is accumulated water, the heating device 100 is activated to melt the ice.

[0077] Executing control instructions: Based on the analysis results, the controller sends control instructions to the heating device 100 and the drainage device. If ice melting is required, the controller starts the heating device 100 and adjusts the heating time and power according to the set target melting strategy. If drainage is required, the controller starts the drainage device and adjusts the drainage time and frequency according to the set target discharge strategy.

[0078] Feedback mechanism: The system should have the ability to self-learn and optimize, and continuously adjust the operation instructions by recording the results after each operation to improve the control accuracy and efficiency. For example, if water still exists after a drainage, the system may shorten the time interval for the next drainage; if the temperature rises quickly after heating, the system may reduce the heating time. Of course, it can also be set to record all operation logs, including start time, stop time, temperature change, liquid level change, etc. Automatically generate reports for management personnel to review, helping to understand the working status and performance of the system.

[0079] Therefore, by real-time monitoring of the environmental characteristics in the air cylinder, timely response to water accumulation and ice formation is ensured. Dynamic adjustment of the heating and drainage strategies according to different conditions not only ensures the reliability of the system, but also saves energy. In addition, it effectively prevents brake system failures caused by water accumulation or ice formation to ensure driving safety. In other words, under non-extreme weather conditions, the system will reasonably arrange the drainage frequency according to the environmental data in the air cylinder to ensure that the air cylinder remains dry without wasting air pressure. Once the temperature drops below freezing, the system will activate dual monitoring of liquid level and ice formation. If signs of ice formation are found, the heating device 100 will be immediately started to melt the ice to ensure that the air cylinder is always in the best working condition.

[0080] Obviously, by introducing intelligent control logic and real-time monitoring technology, the drain valve control method provided by this application realizes the precise management of water accumulation and ice formation in the air tank, which not only improves the reliability and safety of the system, but also significantly reduces energy consumption and maintenance costs. This provides strong support for the stable operation of the vehicle braking system, especially under complex and changeable climatic conditions.

[0081] In some embodiments, before obtaining the operation instruction of the drain valve 10, the process further includes:

[0082] Acquire environmental characteristic data corresponding to the drain valve 10, wherein the environmental characteristic data is used to characterize the environmental category in which the drain valve 10 is located; wherein the environmental characteristic data includes a dielectric constant;

[0083] Comparing the environmental characteristic data with corresponding preset characteristic data to obtain a comparison result;

[0084] According to the comparison result, the target working operation mode corresponding to the drain valve 10 is determined, and the operation instruction is generated based on the target working operation mode.

[0085] In these embodiments, a dielectric constant sensor is used to detect the dielectric constant of the medium in the gas cylinder to characterize the environment category (such as humidity, whether there is water or ice) in which the gas cylinder is located. The collected environmental characteristic data is stored in a local or cloud database for subsequent analysis and optimization. The data can be transmitted to a central control system or other monitoring equipment through a wireless communication module.

[0086] Load preset environmental characteristic data from the database or built-in configuration files, which define typical characteristic values ​​under different environmental categories (such as standard temperature range, humidity threshold, dielectric constant range, etc.).

[0087] The controller compares the real-time collected environmental characteristic data with the preset characteristic data and calculates the difference or matching degree. For the dielectric constant, the humidity state in the gas cylinder (such as dry, wet or frozen) can be determined by comparing the currently measured dielectric constant value with the preset standard value.

[0088] According to the comparison situation, a detailed comparison result is generated, including but not limited to the environmental category (such as high humidity environment, low humidity environment, low temperature icing environment, etc.) and the specific differences of each characteristic parameter.

[0089] According to the comparison result, the target working operation mode corresponding to the drain valve 10 is determined, and the operation instruction is generated based on the target working operation mode: based on the comparison result, the controller selects the target working operation mode that best suits the current environmental conditions.

[0090] For example, in a high humidity environment: increase the drainage frequency to ensure that the air cylinder remains dry. In a low humidity environment: reduce unnecessary drainage operations to reduce energy consumption. In a low temperature freezing environment: activate the heating device 100 to prevent water from accumulating and freezing in the air cylinder.

[0091] According to the selected target operation mode, specific operation instructions are generated. These parameters are used to determine the target melting strategy of the heating device 100 and the target discharge strategy of the drainage device. The target melting strategy defines the conditions under which the heating device 100 is started and the heating time and intensity. The target discharge strategy defines the conditions under which the drainage device is started and the time interval and frequency of drainage.

[0092] For example, in this embodiment, based on the different dielectric constants of air, water, water-oil mixture and ice, the water accumulation state, water accumulation depth and ice state in the gas storage cylinder can be obtained by detecting the dielectric constant of the medium between the first conductive member 220 and the second conductive member 210 set in the gas storage cylinder, and then by controlling the power-on state of the heating device 100 or the exhaust device, the heating and drainage functions can be controlled. The dielectric constants and corresponding states are shown in Table 1 below:

[0093] Table 1

[0094] Dielectric constant Air tank status description 1 to 2 No water accumulation 3 to 4 Freezing of the water cavity 5 to 55 There is water but it is not full Not less than 55 The water is full

[0095] According to Table 1, it is obvious that by obtaining the dielectric constant of the water accumulation chamber in the gas cylinder, the environmental characteristic data in the gas cylinder, such as the water accumulation depth, the freezing state, etc., can be determined.

[0096] In some embodiments, determining the target operation mode corresponding to the drain valve 10 according to the comparison result, and generating the operation instruction based on the target operation mode, includes:

[0097] Based on the comparison result, determining the target environment category corresponding to the environmental characteristic data;

[0098] Obtaining a mode correspondence relationship corresponding to the drain valve 10, wherein the mode correspondence relationship is used to characterize a correspondence relationship between an environment category and a working operation mode;

[0099] Based on the mode correspondence corresponding to the drain valve 10 and the target environment category, the target working operation mode corresponding to the drain valve 10 is determined in multiple working operation modes, and the operation instruction is generated based on the target working operation mode.

[0100] In these embodiments, in order to more accurately determine the target working operation mode of the drain valve 10 and generate corresponding operation instructions, the method provided in the present application introduces the correspondence between the environmental category and the working operation mode in the process of determining the target working operation mode according to the comparison results.

[0101] The controller compares the real-time collected environmental characteristic data with the preset characteristic data and calculates the difference or matching degree. For the dielectric constant, the humidity state in the gas cylinder (such as dry, wet or frozen) can be determined by comparing the currently measured dielectric constant value with the preset standard value.

[0102] According to the comparison situation, a detailed comparison result is generated, including but not limited to the environmental category (such as high humidity environment, low humidity environment, low temperature icing environment, etc.) and the specific differences of each characteristic parameter.

[0103] Furthermore, according to the environmental characteristic data in the comparison result, the target environment category that the current gas cylinder is in is determined. For example, if the dielectric constant indicates that there is a lot of water and the temperature is below the freezing point, it is determined to be a "low temperature icing environment".

[0104] Wherein, obtaining the mode correspondence relationship: obtaining a preset mode correspondence relationship from a system internal database or an external configuration file, the relationship representing the mapping between different environment categories and work operation modes.

[0105] For example, a high humidity environment corresponds to a frequent drainage mode, a low humidity environment corresponds to a reduced drainage mode, and a low temperature icing environment corresponds to a heating and ice melting mode.

[0106] Based on the mode correspondence and the target environment category: among multiple preset working modes, according to the mode correspondence and the determined target environment category, the target working mode that best suits the current conditions is selected. For example, if the target environment category is "low temperature icing environment", the "heating and ice melting mode" is selected.

[0107] Based on the target operation mode: According to the selected target operation mode, specific operation instructions are generated, which are used to control the operation of the heating device 100 and the drainage device. For example, in the "heating and ice melting mode", instructions are generated to start the heating device 100 and adjust its power; in the "frequent drainage mode", instructions are generated to increase the drainage frequency.

[0108] The controller sends the generated operation instructions to the heating device 100 and the drainage device to ensure that they operate according to the set target working operation mode. If ice melting is required, the controller will start the heating device 100 and adjust the heating time and power according to the set target melting strategy. If drainage is required, the controller will start the drainage device and adjust the drainage time and frequency according to the set target discharge strategy.

[0109] In some embodiments, the working operation mode includes:

[0110] Conventional inspection operation mode, heating and ice melting operation mode, accelerated inspection operation mode and drainage operation mode; wherein, if the conventional inspection operation mode is the target working operation mode, the drainage valve 10 is controlled to detect the environmental characteristic data corresponding to the drainage valve 10 according to the first preset period;

[0111] If the heating and ice-melting operation mode is the target operation mode, the heating device 100 of the drain valve 10 is controlled to be powered on to generate heat to melt the ice in the gas storage cylinder, and the environmental characteristic data corresponding to the drain valve 10 is detected according to the first preset period;

[0112] If the accelerated inspection operation mode is the target operation mode, the drain valve 10 is controlled to detect the environmental characteristic data corresponding to the drain valve 10 according to a second preset period; wherein the first preset period is greater than the second preset period;

[0113] If the drainage operation mode is the target working operation mode, the drainage device of the drainage valve 10 is controlled to discharge the accumulated water in the air storage cylinder, and the environmental characteristic data corresponding to the drainage valve 10 is detected according to the second preset period.

[0114] In these embodiments, in order to more accurately manage and respond to the water accumulation and ice state in the gas storage cylinder, the drain valve control method provided in this application defines four different working modes and adopts corresponding control strategies according to these modes. The following are the detailed steps of the method, especially the specific operations for different working modes:

[0115] Conventional inspection operation mode: suitable for regular inspection under normal environmental conditions. The drain valve 10 is controlled to detect environmental characteristic data corresponding to the drain valve 10 according to a first preset period.

[0116] Heating and ice-melting operation mode: suitable for preventing or melting ice in the gas cylinder in a low temperature environment. The heating device 100 of the drain valve 10 is powered on to generate heat to melt the ice in the gas cylinder, and the environmental characteristic data corresponding to the drain valve 10 is detected according to the first preset period.

[0117] Accelerated inspection operation mode: Applicable to situations where frequent monitoring of environmental characteristic data is required, such as when the humidity is high. The drain valve 10 is controlled to detect the environmental characteristic data corresponding to the drain valve 10 according to a second preset period (shorter than the first preset period).

[0118] Drainage operation mode: Applicable to the situation where the water in the air storage cylinder needs to be discharged in time. The drainage device of the drainage valve 10 is controlled to discharge the water in the air storage cylinder, and the environmental characteristic data corresponding to the drainage valve 10 is detected according to the second preset period.

[0119] The specific operations of different working modes are as follows:

[0120] Conventional inspection operation mode: the drain valve 10 is controlled to detect the environmental characteristic data corresponding to the drain valve 10 according to the first preset period (longer period). Under normal environmental conditions, frequent monitoring or operation is not required, saving energy consumption.

[0121] Heating and ice-melting operation mode: The heating device 100 of the drain valve 10 is controlled to generate heat to melt the ice in the gas storage cylinder. The environmental characteristic data corresponding to the drain valve 10 is detected according to the first preset period (longer period). In a low temperature environment, there is a risk of ice formation or ice formation has been detected.

[0122] Accelerated inspection operation mode: Control the drain valve 10 to detect the environmental characteristic data corresponding to the drain valve 10 according to the second preset period (shorter period). When the environmental characteristic data needs to be frequently monitored, such as when the humidity is high, ensure that signs of water accumulation or ice formation are found in time. At the same time, when it is ensured that there is water accumulation in the air reservoir, shorten the inspection cycle and increase the inspection frequency to ensure real-time monitoring of the depth of water accumulation, and be able to discharge the water when the depth of water accumulation reaches the set threshold, thereby reducing the impact on the braking effect.

[0123] Drainage operation mode: Control the drainage device of the drainage valve 10 to discharge the accumulated water in the air storage cylinder. Detect the environmental characteristic data corresponding to the drainage valve 10 according to the second preset period (shorter period) to ensure that the accumulated water is completely discharged.

[0124] Obviously, by introducing four different working modes, the drain valve control method provided by the present application can respond to different environmental conditions more flexibly and intelligently, and realize efficient automatic control. This not only improves the reliability and safety of the system, but also significantly reduces energy consumption and maintenance costs, and provides strong support for the stable operation of the vehicle braking system.

[0125] In some embodiments, if the conventional inspection operation mode is the target operation mode, controlling the drain valve 10 to detect the environmental characteristic data corresponding to the drain valve 10 according to the first preset period also includes:

[0126] If the conventional inspection operation mode is the target working operation mode, the drain valve 10 is controlled to be powered on 930 according to the first preset period, and the environmental characteristic data corresponding to the drain valve 10 is detected.

[0127] In these embodiments, the drain valve control method provided in the present application further refines the operations of turning on the power supply 930 and detecting environmental characteristic data in the conventional inspection operation mode.

[0128] In the normal inspection operation mode, the drain valve 10 is controlled to be connected to the power supply 930 according to the first preset period, and the environmental characteristic data corresponding to the drain valve 10 is detected. That is, the controller will connect the power supply 930 of the drain valve 10 every first preset period (for example, every hour). After the power supply 930 is turned on, the sensor is immediately started to collect environmental characteristic data (such as temperature, humidity, liquid level, dielectric constant, etc.). After completing the data collection, the power supply 930 of the drain valve 10 is disconnected to save energy.

[0129] Under normal environmental conditions, frequent monitoring or operation is not required, but regular checks are required to ensure that the system is operating normally.

[0130] For example, the first preset period may be 10 minutes, 20 minutes, 30 minutes, 40 minutes or 50 minutes, etc., which is not specifically limited here.

[0131] For example, the second preset period may be 10 minutes, 20 minutes, 30 minutes, 40 minutes or 50 minutes, etc., which is not specifically limited here. It should be noted that it is sufficient as long as the second preset period is smaller than the first preset period.

[0132] like Figure 2As shown, in some embodiments, the present application further provides a drain valve control device 800, and the drain valve control device 800 includes:

[0133] An acquisition module 810, the acquisition module 810 is used to acquire an operation instruction of a drain valve 10, the drain valve 10 is provided in an air storage cylinder, the drain valve 10 comprises a heating device 100 and a drain device, the operation instruction is used to determine a target melting strategy for the heating device 100 to melt ice in the air storage cylinder, and a target discharge strategy for the drain device to discharge the accumulated water in the air storage cylinder;

[0134] The control module 820 is used to control the operation of the heating device 100 and the drainage device based on the operation instruction.

[0135] like Figure 3 and Figure 4 As shown, in some embodiments, the present application also provides a drain valve 10, which includes a drain device, a heating device 100, a detection device 200 and a control device, the drain device is used to discharge the accumulated water in the gas cylinder; the heating device 100 is used to melt the ice in the gas cylinder; the detection device 200 includes a first conductive member 220, a second conductive member 210 and a dielectric constant detection member, the surface of the first conductive member 220 is coated with an insulating layer 230, the first conductive member 220 and the second conductive member 210 are horizontally spaced, the dielectric constant detection member is electrically connected to the first conductive member 220 and the second conductive member 210, respectively, and the dielectric constant detection member is used to detect the dielectric constant between the first conductive member 220 and the second conductive member 210; the control device is electrically connected to the dielectric constant detection member, the drain device and the heating device 100, respectively, and the control device is used to control the operation of the heating device 100 and the drain device according to the dielectric constant.

[0136] In these embodiments, in order to achieve intelligent management and efficient control of water accumulation and ice formation in the gas cylinder, the present application provides an intelligent drain valve 10. The drain valve 10 integrates a drain device, a heating device 100, a detection device 200 and a control device, and can automatically adjust the heating and draining operations according to the change of the dielectric constant in the gas cylinder.

[0137] The drainage device is used to drain the accumulated water in the gas storage cylinder. Usually, the drainage device includes one or more electromagnetic valves or electromagnetic valve components, which are controlled to open and close by a controller.

[0138] The heating device 100 is used to melt ice in the gas cylinder. The heating device 100 can be a resistance heater, a heating wire or other types of heating elements, which are installed inside or outside the gas cylinder to ensure that heat can be effectively transferred to the medium in the gas cylinder.

[0139] Illustratively, in this embodiment, the heating element is installed at the portion of the drain valve 10 located inside the gas reservoir.

[0140] In the detection device 200, the surface of the first conductive member 220 is coated with an insulating layer 230 to prevent direct current from passing. The second conductive member 210 is horizontally spaced apart from the first conductive member 220 to form a capacitive sensor. The dielectric constant detection member is electrically connected to the first conductive member 220 and the second conductive member 210 respectively to detect the dielectric constant between the two.

[0141] The dielectric constant detection element determines the dielectric constant in the gas cylinder by measuring the change in capacitance between the first conductive element 220 and the second conductive element 210. When the medium in the gas cylinder changes (such as increased humidity, water accumulation or ice formation), the dielectric constant will also change accordingly. By analyzing the change in the dielectric constant, the environmental state in the gas cylinder (such as dryness, humidity, water accumulation or ice formation) can be determined.

[0142] The control device controls the operation of the heating device 100 and the drainage device according to the dielectric constant data provided by the detection device 200. The control device is electrically connected to the dielectric constant detection member, the drainage device and the heating device 100 respectively to realize centralized control. If the dielectric constant is detected to indicate ice formation, the heating device 100 is started to melt the ice. If the accumulated water is detected to exceed the preset threshold, the drainage device is started to drain the water. The control strategy is dynamically adjusted according to the set working operation mode (such as conventional inspection, heating and ice melting, accelerated inspection, drainage).

[0143] Exemplarily, the control device may be a programmable controller, a single chip microcomputer or a distributed control system, etc.

[0144] In addition, the workflow is as follows:

[0145] Initialize the system: The control device starts and initializes, preparing to receive data from the detection device 200.

[0146] Collecting environmental characteristic data: The dielectric constant detection element in the detection device 200 monitors the dielectric constant between the first conductive element 220 and the second conductive element 210 in real time, and transmits the data to the control device.

[0147] Data analysis and decision-making: The control device analyzes the collected dielectric constant data to determine the current state of the gas cylinder (such as dry, wet, waterlogged or frozen). Based on the analysis results, it is determined whether the heating device 100 or the drainage device needs to be started.

[0148] Execute control instructions: If ice melting is required, the controller will start the heating device 100 and adjust the heating time and power according to the set target melting strategy. If drainage is required, the controller will start the drainage device and adjust the drainage time and frequency according to the set target discharge strategy.

[0149] Therefore, by integrating the drainage device, the heating device 100, the detection device 200 and the control device, the drainage valve 10 provided by the present application realizes the accurate management of the water accumulation and ice state in the gas storage cylinder, which not only improves the reliability and safety of the system, but also significantly reduces the energy consumption and maintenance cost. In particular, the dielectric constant detection element in the detection device 200 can monitor the environmental state in the gas storage cylinder in real time, providing key data support for intelligent control.

[0150] In more detail, when it is detected that the accumulated water is full, the drainage device will be powered on. At this time, the valve core 500 of the drain valve 10 overcomes the thrust of the return spring 600 under the action of the electromagnetic force and starts to move downward. The accumulated water in the water accumulation chamber of the air storage cylinder enters the lower liquid accumulation chamber 400 of the drain valve 10 through the valve body outlet 300 of the upper drain valve 10 under the high-pressure air pressure, and then enters the drain port 700 of the drain valve 10 through the drainage channel 510 of the valve core 500 to be discharged from the air storage cylinder. At this time, continue to detect until the accumulated water is completely drained. If it is detected that there is no accumulated water, the electromagnetic valve will be powered off, and the valve core 500 will return to its original position under the thrust of the return spring 600, closing the drain port 700, and the drainage operation is completed. After that, the drain valve 10 will enter the regular inspection operation mode again.

[0151] In some embodiments, the drain valve 10 also includes a metal filter cover, and the metal filter cover and the dielectric constant detection component are electrically connected, so that the metal filter cover constitutes a second conductive member 210, and the second conductive member 210 is arranged in the metal filter cover, and a gap is defined between the second conductive member 210 and the inner wall of the metal filter cover.

[0152] In these embodiments, in order to further optimize the design of the drain valve 10 and improve its reliability and detection accuracy, the drain valve 10 provided in the present application adds a metal filter mesh cover on the original basis, and electrically connects it to the dielectric constant detection component, so that the metal filter mesh cover constitutes the second conductive component 210, thereby reducing the number of components.

[0153] The second conductive member 210 is disposed in the metal filter screen and is electrically connected to the metal filter screen to form a complete conductive loop. The metal filter screen constitutes a part of the second conductive member 210 and plays a dual role of physical filtering and electrical connection. The dielectric constant detection member is electrically connected to the first conductive member 220 and the metal filter screen (as the second conductive member 210) respectively to detect the dielectric constant between the two.

[0154] The dielectric constant detection element determines the dielectric constant in the gas cylinder by measuring the change in capacitance between the first conductive element 220 and the metal filter screen. When the medium in the gas cylinder changes (such as increased humidity, water accumulation or ice formation), the dielectric constant will also change accordingly. By analyzing the change in the dielectric constant, the environmental state in the gas cylinder (such as dryness, humidity, water accumulation or ice formation) can be determined.

[0155] The metal filter screen is arranged at the entrance of the gas storage cylinder or near the detection device 200. The second conductive member 210 is arranged in the metal filter screen, and a gap is defined between the two to ensure uniform air circulation and electric field distribution, and avoid interference with the accuracy of dielectric constant detection. The metal filter screen is electrically connected to the dielectric constant detection member to form a complete electrical circuit, ensuring stable transmission of the detection signal.

[0156] For example, since the gas cylinder is disposed vertically, the first conductive member and the second conductive member are both disposed to extend vertically.

[0157] In some embodiments, the dielectric constant detection element is configured as a capacitive liquid level sensor.

[0158] In these embodiments, the capacitive liquid level sensor is based on the capacitance principle and uses the different dielectric constants of dielectrics (such as air, water, ice, etc.) to detect the liquid level and dielectric properties in the gas cylinder. Specifically, the capacitive liquid level sensor is composed of two parallel plate capacitors, namely the first conductive member 220 and the metal filter screen (as the second conductive member 210). When the medium in the gas cylinder changes, the dielectric of the capacitor also changes, resulting in a change in the capacitance value.

[0159] Capacitance change and liquid level relationship: As the liquid level in the gas reservoir increases, more liquid (with a higher dielectric constant) replaces air (with a lower dielectric constant), causing the capacitance value to increase. Conversely, when the liquid level drops, the capacitance value decreases.

[0160] Capacitance change and dielectric properties: Different media (such as water and ice) have different dielectric constants, so the change in capacitance value can also be used to distinguish the state of the medium in the gas cylinder (such as whether there is ice).
