[0106] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0107] In order to solve the above technical problems, the embodiments of the present disclosure provide a liquid inflow detection method and device, an electronic device, and a storage medium. The electronic device includes a processor, a USB Type-C port, and a detection circuit. The above processor can be a CPU processor in an electronic device, or a newly added device with processing functions, such as a single-chip microcomputer, or a chip with processing functions in an electronic device, such as a power management chip.

[0108] See also Figure 1 The USB Type-C port includes an A side and a B side, each of which is provided with a group of pins with the same function and in the opposite order. Taking the A side pins as an example, pins A1 to A12 are respectively GND, TX1+, TX1-, VBUS, CC1, D+, D-, SBU1, VBUS, RX2-, RX2+ and GND.

[0109] In one example, see Figure 2 , the detection circuit includes an ADC sampler, a power switch K1, a pull-up resistor R1 and multiple groups of detection switches K2; the first end of the pull-up resistor R1 is electrically connected to the target power supply (such as 1.875V, adjustable), and the first end of the pull-up resistor R1 is electrically connected to the first end of the power switch K1; the second end of the power switch K1 is electrically connected to the input end of the ADC sampler and the second end of each detection switch K2 respectively; the first end of each detection switch K2 is electrically connected to each pin in the first pin. Among them, the first pin includes at least one pin of the A side or B side pin of the USB Type-C port except the ground pin, such as at least one of A2 to A11.

[0110] In this example, the processor is electrically connected to the control end of the power switch K1, the control end of each group of detection switches K2, and the output end of the ADC sampler. The distance between the first pin and the ground pin is less than or equal to the preset distance, so that when the liquid enters between the pin and the ground pin, the pin and the ground can be short-circuited. The resistance to ground R_gnd formed when the liquid short-circuits the pin is as follows: Figure 2 shown.

[0111] In one example, the detection circuit is used in conjunction with a ground pin in a USB Type-C port to detect the resistance value of the first pin in the second state. Figure 2The working principle of the detection circuit shown is:

[0112] When not detected, the power switch K1 is disconnected and each group of detection switches K2 is disconnected, and the connection status between each pin and the ground pin is unknown, that is, whether liquid is added is unknown. At this time, it is necessary to determine the connection status between each pin and the ground pin. When there is a detection demand, the processor can control the power switch K1 to close and each group of detection switches K2 to close in turn. When there is liquid between a pin and the ground pin, the liquid is equivalent to the wire shorting the pin to the ground pin. The equivalent resistance R_gnd between the liquid and the pin forms a voltage divider circuit with the pull-up resistor R1. At this time, the ADC sampler can collect the voltage division of the equivalent resistance and convert the voltage division into a resistance value to output to the processor. Repeat the above switching operation to switch to each detection switch K2 in turn. The processor can obtain the resistance value of each pin in the first pin, which is subsequently referred to as the first resistance value.

[0113] In another example, the detection circuit is used in conjunction with a power pin in a USB Type-C port to detect a voltage value of a second pin in a first state. Figure 3 The working principle of the detection circuit shown is:

[0114] When not detected, the power switch K1 is disconnected and each group of detection switches K2 is disconnected, and the connection status between each pin and the power pin is unknown, that is, whether liquid is added is unknown. At this time, it is necessary to determine the connection status between each pin and the power pin. When there is a detection requirement, the processor can control the power switch K1 to close and each group of detection switches K2 to close in turn. When there is liquid between a pin and the power pin, the liquid is equivalent to a wire. At this time, the pin is short-connected to the power pin, and the equivalent resistance R_vbus between the liquid and the pin, that is, the voltage of the detection pin is the power supply voltage VBUS. At this time, the ADC sampler can collect the voltage value of the pin and output the voltage value to the processor. Repeat the above switching operation to switch to each detection switch K2 in turn. The processor can obtain the voltage value of each pin in the second pin, which is subsequently referred to as the first voltage value.

[0115] based on Figure 1 to Figure 3 The electronic device shown in the figure, the embodiment of the present disclosure also provides a liquid inflow detection method, Figure 4 Flow chart of a liquid inflow detection method according to an embodiment of the present disclosure. Figure 4 , a liquid inlet detection method includes steps 41 to 43.

[0116] In step 41, the connection state of the USB Type-C port is obtained; the connection state includes a first state of being connected to an external device and a second state of not being connected to the external device.

[0117] In this step, the USB Type-C port of the electronic device may be electrically connected to the USB Type-C port of the external device. The external device may include, but is not limited to, a charging device, other electronic devices, headphones, a data cable, etc. After docking with the external device, the processor of the electronic device may determine the connection state of the USB Type-C port, which includes a first state of being connected to the external device and a second state of not being connected to the external device.

[0118] In one example, when the electronic device is docked with the external device, the configuration pins CC of the USB Type-C ports of the two devices are docked to form a communication channel. After the communication channel is established, the pull-up resistors (or pull-down resistors) in the electronic device and the external device will form a voltage divider circuit to determine whether the USB Type-C port is in a forward plug state or a reverse plug state. Then, the processor can obtain the forward plug state or the reverse plug state of the USB Type-C port, and determine that the connection state is a first state connected to the external device. Alternatively, the processor cannot obtain the forward plug state or the reverse plug state of the USB Type-C port, or is in a suspended state, and determines that the connection state is a second state that is not connected to the external device.

[0119] In another example, when the electronic device is docked with an external device, the power pin VBUS of the USB Type-C port of the electronic device will be powered. The processor can obtain the voltage value at the power pin VBUS, and when the voltage value at the power pin VBUS is a first voltage value (such as 0V), the processor can determine that the connection state of the USB Type-C port is a second state that is not connected to the external device; when the voltage value at the power pin VBUS is a second voltage value (such as VCC, such as 2V), the processor can determine that the connection state of the USB Type-C port is a first state that is connected to the external device.

[0120] In another example, when the electronic device is docked with the external device, the two will determine the role of the electronic device, such as a downstream facing port (DFP), an upstream facing port (UFP), a dual role port (DRP), etc. When the role of the USB Type-C port of the electronic device is detected, the processor can determine that the connection state of the USB Type-C port is a first state of being connected to the external device; when the role of the USB Type-C port of the electronic device cannot be detected, the processor can determine that the connection state of the USB Type-C port is a second state of not being connected to the external device.

[0121] It should be noted that the above embodiments describe solutions for obtaining the connection status of the USB Type-C port of an electronic device. Those skilled in the art can select a corresponding solution according to the specific scenario. If the connection status can be determined, the corresponding solution falls within the protection scope of this disclosure.

[0122] In step 42, in response to determining that the connection state is the second state, determining whether liquid has entered the port according to the resistance value of the first pin of the USB Type-C port.

[0123] In this step, when it is determined that the connection state of the USB Type-C port is the second state, the processor can determine whether the port has been liquid-infiltrated according to the resistance value of the first pin of the USB Type-C port, see Figure 2 , including step 21 and step 22.

[0124] In step 21, the processor may detect a first resistance value of each of the first pins of the USB Type-C port.

[0125] Considering that the USB Type-C port of the electronic device is a receiving end (or female end), liquids are usually splashed into the middle area of ​​the A side and / or the B side. In one example, the first pin is pre-configured. Figure 1 , the first pin may include a first auxiliary communication pin SBU1 and a first data communication pin D+ and a second data communication pin D- on the same side thereof; and / or, the first pin includes a second auxiliary communication pin SBU2 and a first data communication pin D+ and a second data communication pin D- on the same side thereof. In this way, this example detects liquid inflow through three pins in the middle area, which is conducive to improving the accuracy of the detection result.

[0126] In this step, the processor can obtain the resistance value of each pin in the first pin, which is hereinafter referred to as the first resistance value for distinction. The scheme for obtaining the first resistance value can be referred to in Figure 2 The content of the example solution will not be repeated here.

[0127] In step 22, in response to determining that the first resistance value satisfies a first preset condition, the processor may determine that a first event of liquid intrusion into the USB Type-C port is detected.

[0128] A first preset condition is stored in the electronic device, and the first preset condition includes that the resistance value of each pin in the first pin is less than or equal to a resistance value threshold.

[0129] The above resistance threshold can be detected experimentally. Considering the use scenarios of electronic devices, the liquid entering the USB Type-C port may include but is not limited to sweat, tap water, rainwater, beverages, etc. In this way, various liquids can be dropped into the USB Type-C port to detect the resistance value of the above equivalent resistor when different liquids splash into the USB Type-C port; then, the maximum value in the detection value or the preset multiple of the maximum value (such as 1 to 1.5) is determined as the resistance threshold.

[0130] In this step, the processor can compare the first resistance value of each pin in the first pin with the resistance value threshold. When the first resistance value of each pin in the first pin is less than the above resistance value threshold, it is determined that the first resistance value meets the first preset condition. In other words, the first preset condition includes: the first resistance value of each pin in the first pin is less than or equal to the resistance value threshold. At this time, the processor can determine to detect a first event of liquid inflow into the USB Type-C port. When it is determined that the first resistance value does not meet the first preset condition, the processor can determine to detect a second event of no liquid inflow into the USB Type-C port.

[0131] It should be noted that, considering that the splashed liquid is usually one type of liquid, the first resistance value of each pin may be approximately equal, so the first resistance value of each pin is compared with the resistance value threshold to simplify the processing scheme.

[0132] In one example, after determining that a first event of liquid intrusion into the USB Type-C port is detected, a signal may be generated as follows: Figure 5 The first pop-up window containing the reminder information of the liquid inflow event shown in FIG. 1 may be used to remind that the charging port is wet. Figure 6 The first pop-up window shown contains reminder information of a liquid ingress event, for example, the reminder information of a liquid ingress event is used to prompt that the charging port is wet and affects normal use, and user interaction is required for charging.

[0133] The processor detects the second resistance value of each pin in the first pin of the USB Type-C port, wherein the manner of obtaining the second resistance value and the first resistance value is the same, which will not be repeated here. Then, the processor can compare the second resistance value of each pin in the first pin with the resistance value threshold to determine whether the second resistance value meets the second preset condition. Among them, the second preset condition includes: the second resistance value of each pin in the first pin is greater than the resistance value threshold. When it is determined that the second resistance value does not meet the second preset condition, the processor can continue to perform the step of detecting the second resistance value of each pin in the first pin of the USB Type-C port. When it is determined that the second resistance value meets the second preset condition, the processor can determine that a third event of liquid disappearance has been detected in the USB Type-C port, and at this time, the second resistance value can be stopped, that is, liquid inlet detection can be stopped. After it is determined that the third event of liquid disappearance has been detected in the USB Type-C port, a second pop-up window containing reminder information of liquid disappearance can be generated, or no pop-up window is generated.

[0134] In step 43, in response to determining that the connection state is the first state, determining whether liquid has entered the port according to the voltage value of the second pin of the USB Type-C port.

[0135] In this step, when it is determined that the connection state of the USB Type-C port is the first state, the processor can determine whether the port has a liquid inlet event according to the voltage value of the second pin of the USB Type-C port, see Figure 7 , including step 71 and step 72.

[0136] In step 71, the processor may obtain a first voltage value of each of the second pins of the USB Type-C port.

[0137] In this step, the second pin can be preconfigured based on the way of preconfiguring the first pin. In one example, the second pin includes the first auxiliary communication pin SBU1 and the first configuration pin CC1 on the same side thereof; and / or, the second pin includes the second auxiliary communication pin SBU2 and the second configuration pin CC2 on the same side thereof.

[0138] In this step, the processor may obtain the first voltage value of each pin of the second pin of the USB Type-C port, wherein the scheme for obtaining the first voltage value may refer to Figure 3 The content of the example solution will not be repeated here.

[0139] It should be noted that, considering that when no liquid enters the USB Type-C port, each pin in the USB Type-C port is physically connected to the corresponding pin of the external device, the potential at the pin is much smaller than the power supply voltage.

[0140] In step 72, in response to determining that the first voltage value satisfies a third preset condition, it is determined that a first event of liquid intrusion into the USB Type-C port is detected.

[0141] In this step, a third preset condition is stored in the electronic device, and the third preset condition can be adjusted according to the second pin. In one example, the third preset condition includes: the voltage value at the first configuration pin CC1 is greater than the first voltage threshold Vcc_set1 and the voltage value at the first auxiliary communication pin SBU1 is greater than the third voltage threshold Vsbu; and / or, the third preset condition includes: the voltage value at the second configuration pin CC2 is greater than the second voltage threshold Vcc_set2 and the voltage value at the second auxiliary communication pin SBU2 is greater than the third voltage threshold Vsbu.

[0142] In this step, the processor can compare the first voltage value of each pin in the second pin with their respective voltage thresholds, for example, compare the voltage value at the first configuration pin CC1 with the first voltage threshold Vcc_set1, compare the voltage value at the first auxiliary communication pin SBU1 with the third voltage threshold Vsbu; and / or, compare the voltage value at the second configuration pin CC2 with the second voltage threshold Vcc_set2, compare the voltage value at the second auxiliary communication pin SBU2 with the third voltage threshold Vsbu.

[0143] It should be noted that the setting method of the first voltage threshold Vcc_set1, the second voltage threshold Vcc_set2 and the third voltage threshold Vsbu can refer to the setting method of the voltage value threshold, that is, various types of liquids are dripped into the USB Type-C port respectively, and then the voltage value input by the ADC sampler is obtained, and then the maximum value of the sampled voltage value or a preset multiple (such as 1 to 1.5) of the maximum value is taken as the first voltage threshold Vcc_set1, the second voltage threshold Vcc_set2 or the third voltage threshold Vsbu. In this way, when liquid is introduced, the voltage value of the pin can be pulled down from the power supply voltage until it is less than or equal to the above-mentioned voltage thresholds, that is, when the voltage value output by the ADC sampler is less than or equal to the voltage value threshold, it is determined that liquid is introduced.

[0144] In one example, when it is determined that the first voltage value of each pin of the second pin does not meet the third preset condition, the processor may determine that the second event that no liquid inflow occurs to the USB Type-C port is detected. At this time, the processor may stop the liquid inflow detection. In this example, the processor may start a timer, and restart the liquid inflow detection process when the timer counts a preset time.

[0145] In one example, when it is determined that the first voltage value of each pin of the second pin meets the third preset condition, the processor can determine that a first event of liquid inflow is detected in the USB Type-C port. Then, the processor can detect the voltage value of each pin in the second pin of the USB Type-C port, which is hereinafter referred to as the second voltage value. Among them, the method for obtaining the second voltage value can refer to the method for obtaining the first voltage value. The processor can determine whether the second voltage value of each pin in the second pin meets the fourth preset condition. Among them, the above-mentioned fourth preset condition includes: the second voltage value at the first configuration pin CC1 is less than or equal to the first voltage threshold Vcc_set1 and the second voltage value at the first auxiliary communication pin SBU1 (on the same side of CC1) is less than or equal to the third voltage threshold Vsbu; and / or, the fourth preset condition includes: the second voltage value at the second configuration pin CC2 is less than or equal to the second voltage threshold Vcc_set2 and the second voltage value at the second auxiliary communication pin SBU2 (on the same side of CC2) is less than or equal to the third voltage threshold Vsbu.

[0146] In one example, when it is determined that the second resistance value satisfies the fourth preset condition, the processor may determine that a third event of liquid disappearance has been detected in the USB Type-C port. At this time, the processor may stop the liquid inflow detection. When it is determined that the second voltage value does not satisfy the fourth preset condition, the step of detecting the second voltage value of each pin in the second pin of the USB Type-C port is performed. After the liquid disappears, the processor may generate a second pop-up window to remind the user that the liquid disappears and the electronic device can be used normally; or the pop-up window may not be generated, so that the user assumes that the electronic device can be used normally.

[0147] Combination Figure 8 The flowchart shown describes a liquid inlet detection method provided by the present disclosure, see Fig. 9 ,include:

[0148] When the electronic device is started up or the screen is turned on, the processor can detect whether an external device is plugged into the USB Type-C port.

[0149] When it is determined that no external device is inserted, the processor can determine whether liquid has entered the USB Type-C port by detecting the resistance value of the first pin.

[0150] The processor can obtain the first resistance value of each pin in the first pin, for example, first collect a group of first resistance values, and then use another group of first resistance values ​​after a preset time interval (such as 500ms, which can be configured). The above two groups of first resistance values ​​can be used separately or weightedly, and the weight value of the first resistance value of the latter group is higher than the weight value of the first resistance value of the former group.

[0151] Taking a set of first resistance values ​​as an example, the processor can determine whether the first resistance value satisfies a first preset condition, and when the first preset condition is not satisfied, the second event of liquid inflow does not occur in the USB Type-C port and liquid inflow detection is stopped. When it is determined that the first resistance value satisfies the first preset condition, the processor can determine that the first event of liquid inflow occurs.

[0152] Then, the processor can obtain the second resistance value of each pin in the first pin according to a set period (for example, 1 to 10 seconds), and determine whether the second resistance value meets the second preset condition. When it is determined that the second resistance value meets the second preset condition, the third event of liquid disappearance is determined; otherwise, the second resistance value continues to be obtained until the liquid disappears.

[0153] When it is determined that an external device is inserted, the processor can determine whether liquid has entered the USB Type-C port by detecting the voltage value of the second pin.

[0154] The processor may obtain the second voltage value of each pin in the second pin, and determine whether the second voltage value satisfies a third preset condition. When it is determined that the third preset condition is not satisfied, the processor may determine that the second event of liquid inflow has not occurred in the USB Type-C port and stop liquid inflow detection. When it is determined that the third preset condition is satisfied, the processor may determine that the first event of liquid inflow has occurred in the USB Type-C port.

[0155] After determining that the first event has occurred, the processor can obtain the second voltage value of each pin in the second pin according to a set period (for example, 1 to 10 seconds), and determine whether the second voltage value meets the fourth preset condition. When it is determined that the second voltage value meets the fourth preset condition, the third event of the disappearance of liquid inflow is determined; otherwise, the second voltage value continues to be obtained until the liquid inflow disappears and the liquid inflow detection is stopped.

[0156] In this embodiment, by identifying liquid ingress into the USB Type-C port in different scenarios, the accuracy of liquid ingress detection can be improved, which is beneficial for users to promptly handle liquid ingress problems and avoid or alleviate the problem of corrosion of the USB Type-C port.
