[0059] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0060] <Method Example>

[0061] The present disclosure provides a splash prevention method, such as Figure 1 As shown, the anti-splashing method may include steps S1100 to S1300 as shown below:

[0062] Step S1100: detecting whether the electronic device is in contact with liquid.

[0063] The electronic device in this embodiment can be any product that can implement the anti-splash method, for example, it can be shoes, headphones, glasses, mobile phone cases, etc.

[0064] In this embodiment, a liquid detection sensor capable of sensing the presence of liquid may be pre-installed in the electronic device. The liquid detection sensor may be a water immersion sensor, a capacitive pipe liquid level sensor, an optical liquid level sensor, a vibration liquid level sensor, a conductivity liquid level sensor, an ultrasonic liquid level sensor, a radar liquid level sensor, etc.

[0065] Water sensors work based on the principle of liquid conductivity. They detect the presence of water using electrodes and then convert the detection result into a dry contact output. These devices are typically in a normally open state. When the two-pole probe becomes wet, the probe conducts, and the sensor outputs a dry contact signal. When the probe is submerged to approximately 1 mm, an alarm is generated.

[0066] Capacitive pipe level sensors use the capacitive sensing principle to detect the presence of liquid in a pipe by measuring changes in capacitance. These sensors can accurately detect a variety of liquids in pipes, including water, wine, and beverages. They are suitable only for non-metallic pipes and are unaffected by the color of the liquid.

[0067] Optical liquid level sensors use a light source and a detector to monitor liquid levels. When the sensor tip is in air, light is reflected back to the detector. However, when the sensor contacts liquid, the light is refracted, reducing the amount of light received by the detector, thereby detecting the presence of liquid.

[0068] Vibrating level sensors detect liquid level changes by changing the frequency of a vibrating element (such as a tuning fork). When the vibrating element comes into contact with liquid, its vibration frequency changes, triggering a switch signal that can be used to detect the presence of liquid.

[0069] Conductivity level sensors detect liquid levels by measuring changes in the liquid's electrical conductivity. They consist of a long probe that transmits a low voltage and a shorter probe whose tip is located at the switch point. When liquid contacts the two probes, current flows through them, activating the switch. These sensors are suitable for detecting the presence of conductive liquids.

[0070] The ultrasonic liquid level sensor transmits ultrasonic pulses, which are reflected on the liquid surface and received by the sensor. The liquid level is calculated based on the time difference between the transmission and reception of the ultrasonic wave and the propagation speed of the ultrasonic wave in the air, thereby determining whether the liquid exists and the height of the liquid level.

[0071] The radar level sensor uses radar technology to work by emitting microwave signals and measuring the time it takes for the signals to be reflected back to the sensor. By calculating the time it takes for the return signal to be reflected, the liquid level can be determined. It can be used to detect the presence and height of liquids.

[0072] The liquid detection sensor of this embodiment can accurately detect whether an electronic device is in contact with liquid.

[0073] In this embodiment, the location of the liquid sensor can be determined according to the usage scenario of the electronic device.

[0074] In an embodiment where the electronic device is a shoe, a liquid detection sensor may be provided on the sole of the shoe to accurately detect whether the sole of the shoe is in contact with liquid.

[0075] In some embodiments, the shoes may include a liquid detection sensor. The position of the liquid detection sensor on the sole of the shoe is determined based on the user's walking habits and the occasion of use of the shoes, and the position where the user first touches the ground during walking. For example, the liquid detection sensor can be set at the position on the sole of the shoe corresponding to the heel, such as Figure 2 shown.

[0076] In some embodiments, the shoe may also include multiple liquid detection sensors, which may be arranged along the front-to-back direction of the shoe, so that different liquid detection sensors touch the ground in different orders while the user is walking.

[0077] By providing the liquid detection sensor in the manner of this embodiment, it is possible to timely and accurately detect whether the sole of the shoe is in contact with liquid.

[0078] Step S1200: When it is detected that the electronic device is in contact with liquid, the flow rate of the liquid to the electronic device is detected.

[0079] In this embodiment, the flow rate of the liquid to the electronic device may be the volume, area, mass, or number of drops of liquid flowing to the surface of the electronic device per unit time, wherein the unit time may be 1 second.

[0080] In some embodiments, detecting the flow rate of liquid to the electronic device includes: detecting the moving speed of the electronic device, and determining the flow rate according to the moving speed.

[0081] In this embodiment, first mapping data reflecting the mapping relationship between the moving speed and the liquid flow rate can be pre-set; according to the moving speed of the electronic device and the first mapping data, the liquid flow rate corresponding to the moving speed of the electronic device is obtained as the flow rate of the liquid to the electronic device.

[0082] The first mapping data may be a first mapping function, or a first comparison table, etc., which is not limited here.

[0083] For the first mapping function, the dependent variable of the first mapping function is the liquid flow rate, and the independent variable is the moving speed. In this way, by substituting the moving speed of the electronic device into the first mapping function, the liquid flow rate corresponding to the moving speed can be obtained as the flow rate of the liquid to the electronic device.

[0084] The first lookup table can be used to find the liquid flow rate corresponding to the movement speed of the electronic device. If the movement speed cannot be directly found in the first lookup table, two values adjacent to the movement speed of the electronic device can be found. Based on these two values and the liquid flow rates corresponding to these two values, the liquid flow rate corresponding to the movement speed can be obtained by interpolation as the liquid flow rate of the electronic device.

[0085] In some embodiments, detecting the flow rate of liquid to the electronic device includes: detecting the pressure of the liquid acting on the electronic device, and determining the flow rate based on the pressure.

[0086] In this embodiment, second mapping data reflecting the mapping relationship between pressure and liquid flow can be pre-set; based on the pressure of the liquid acting on the electronic device and the second mapping data, the liquid flow corresponding to the pressure of the liquid acting on the electronic device is obtained as the flow of the liquid to the electronic device.

[0087] The second mapping data may be a second mapping function, or a second comparison table, etc., which is not limited here.

[0088] For the second mapping function, the dependent variable of the second mapping function is the liquid flow rate, and the independent variable is the pressure. In this way, by substituting the pressure of the liquid acting on the electronic device into the second mapping function, the liquid flow rate corresponding to the pressure of the liquid acting on the electronic device can be obtained as the flow rate of the liquid to the electronic device.

[0089] The second lookup table can be used to find the liquid flow rate corresponding to the pressure exerted by the liquid on the electronic device. This can be used as the flow rate of the liquid to the electronic device. If the pressure cannot be directly found in the second lookup table, two adjacent values of the pressure exerted by the liquid on the electronic device can be found. Based on these two values and the liquid flow rates corresponding to these two values, the liquid flow rate corresponding to the pressure can be obtained by interpolation as the flow rate of the liquid to the electronic device.

[0090] In some embodiments, detecting the flow rate of liquid to the electronic device includes: detecting the moving speed of the electronic device and the pressure of the liquid acting on the electronic device, and determining the flow rate according to the moving speed and the pressure.

[0091] In this embodiment, third mapping data reflecting the mapping relationship between moving speed, pressure and liquid flow can be pre-set; according to the moving speed of the electronic device, the pressure of the liquid acting on the electronic device and the third mapping data, the liquid flow corresponding to the moving speed of the electronic device and the pressure of the liquid acting on the electronic device is obtained as the flow of the liquid to the electronic device.

[0092] The third mapping data may be a third mapping function, or a third comparison table, etc., which is not limited here.

[0093] For the third mapping function, the dependent variable of the third mapping function is the liquid flow rate, and the independent variables are the moving speed and pressure. In this way, by substituting the moving speed of the electronic device and the pressure of the liquid acting on the electronic device into the third mapping function, the liquid flow rate corresponding to the moving speed of the electronic device and the pressure of the liquid acting on the electronic device can be obtained as the flow rate of the liquid to the electronic device.

[0094] For the third lookup table, the liquid flow rate corresponding to the moving speed of the electronic device and the pressure of the liquid acting on the electronic device can be looked up in the third lookup table as the flow rate of the liquid to the electronic device.

[0095] In step S1300 , the fan on the electronic device is controlled to rotate according to the flow of the liquid to the electronic device, and the direction or intensity of the airflow on the surface of the electronic device is adjusted to prevent the liquid from splashing onto the surface of the electronic device.

[0096] In this embodiment, the electronic device may include a controller, a fan and a driving circuit for the fan. When it is detected that the electronic device is in contact with liquid, the controller in the electronic device may control the driving circuit to output a driving signal to the fan to make the fan rotate.

[0097] Furthermore, when it is detected that the electronic device is not in contact with the liquid, the controller may control the drive circuit to stop outputting the drive signal to the fan, so that the fan stops rotating, thereby reducing the power consumption of the electronic device.

[0098] In this embodiment, the fan on the electronic device rotates to change the direction or intensity of the airflow on the surface of the electronic device, forming an umbrella-shaped wind barrier on the surface of the electronic device to prevent liquid from splashing onto the surface of the electronic device.

[0099] In the embodiment where the electronic device is a shoe, the fan can be arranged at the front end of the shoe upper, such as Figure 2 shown.

[0100] When a user is wearing shoes and there is water on the road, the water may splash onto the front of the shoe as the user walks on the road. In order to prevent the liquid on the road from staining the shoes, this embodiment places the fan on the front of the shoe, which can reduce the problem of the liquid on the road staining the shoes.

[0101] According to the embodiments of the present disclosure, when contact between an electronic device and liquid is detected, the fan on the electronic device is controlled to rotate, thereby preventing the liquid from splashing onto the surface of the electronic device and preventing the liquid from soiling the surface of the electronic device.

[0102] In some embodiments, the rotation of a fan on an electronic device is controlled according to the flow rate of liquid to the electronic device, including: controlling the rotation of the fan when the flow rate of liquid to the electronic device is greater than a sixth threshold value; controlling the fan to stop rotating when the flow rate of liquid to the electronic device is less than or equal to the sixth threshold value.

[0103] The sixth threshold may be set in advance according to an application scenario or specific requirements.

[0104] In some embodiments, controlling the rotation of a fan on an electronic device according to the flow rate of liquid to the electronic device includes: determining a target rotation speed of the fan according to the flow rate of liquid to the electronic device; and controlling the rotation of the fan according to the target rotation speed.

[0105] In this embodiment, fourth mapping data reflecting the mapping relationship between flow rate and rotation speed can be pre-set; according to the flow rate of liquid to the electronic device and the fourth mapping data, the rotation speed corresponding to the flow rate of liquid to the electronic device is obtained as the target rotation speed.

[0106] The fourth mapping data may be a fourth mapping function, or a fourth comparison table, etc., which is not limited here.

[0107] For the fourth mapping function, the dependent variable of the fourth mapping function is the rotational speed, and the independent variable is the flow rate. In this way, by substituting the flow rate of the liquid to the electronic device into the fourth mapping function, the rotational speed corresponding to the flow rate of the liquid to the electronic device can be obtained as the target rotational speed.

[0108] The fourth lookup table can be used to find the rotational speed corresponding to the flow rate of the liquid to the electronic device. If the flow rate of the liquid to the electronic device cannot be directly found in the fourth lookup table, two values adjacent to the flow rate of the liquid to the electronic device can be found. Based on these two values and the rotational speeds corresponding to these two values, an interpolation method can be used to obtain the rotational speed corresponding to the flow rate of the liquid to the electronic device as the target rotational speed.

[0109] Through this embodiment, the rotation speed of the fan can be adaptively adjusted according to the flow rate of liquid to the electronic device, which can prevent the liquid from splashing onto the surface of the electronic device and reduce the power consumption of the electronic device.

[0110] In some embodiments, the method further includes: obtaining the posture change frequency of the electronic device; and controlling the fan to rotate in an alternating operating mode according to the posture change frequency, and periodically adjusting the direction or intensity of the airflow on the surface of the electronic device.

[0111] The movement mode of the fan may include at least one of the speed of the fan, the direction of the fan, and the rotation direction of the fan.

[0112] In this embodiment, the posture data of the electronic device may be collected according to a posture sensor provided in the electronic device, and the posture change frequency of the electronic device may be determined according to the collected posture data.

[0113] In an embodiment where the electronic device is a shoe, when a user walks (including running) in the shoe, the user usually changes the posture of the foot at a fixed frequency. Therefore, the acquired posture change frequency can represent the frequency of the user's walking or running.

[0114] A walking cycle of the user is a complete process starting from when one of the user's heels touches the ground to when the foot touches the ground again.

[0115] In this embodiment, the operation mode of the fan changes alternately during each walking cycle of the user, and the alternating change rules of the operation modes can be the same or different, which is not limited here.

[0116] In some embodiments, the method further includes: acquiring posture data of the electronic device; and adjusting the operating mode of the fan according to the posture data.

[0117] In an embodiment where the electronic device is a shoe, when the posture data indicates that the user's foot is in the support phase, the operating mode of the fan can be determined to be the first mode; when the posture data indicates that the user's foot is in the swing phase, the operating mode of the fan can be determined to be the second mode.

[0118] In different motion modes, the speed of the fan may be different, the orientation of the fan may be different, or the rotation direction of the fan may be different.

[0119] Through this embodiment, the operation mode of the fan can be adaptively adjusted according to the posture of the electronic device during the user's walking.

[0120] In some embodiments, when it is detected that the electronic device is not in contact with liquid, step S1100 is re-executed to detect whether the electronic device is in contact with liquid.

[0121] Through this embodiment, when the environment around the electronic device changes, it can be detected in time that the electronic device is in contact with liquid, thereby preventing the liquid from contaminating the surface of the electronic device.

[0122] In some embodiments, the anti-splash method may also include: controlling the microphone of the electronic device to collect sound wave information; when the similarity between the sound wave information and the preset reference sound wave information is greater than or equal to a first threshold, executing step S1100 to detect whether the electronic device is in contact with liquid.

[0123] In an embodiment where the electronic device is a shoe, the sound wave information collected by the microphone may be the sound wave information generated by the shoe moving on the road.

[0124] In some embodiments, sound wave information generated by a user moving on a wet or waterlogged road surface that is prone to splashing may be collected in advance by a microphone as reference sound wave information.

[0125] Furthermore, when it is determined that the similarity between the sound wave information most recently collected by the microphone and the reference sound wave information is greater than or equal to a first threshold, and it is determined that the user is wearing shoes and moving on a wet or water-logged road surface that is prone to splashing, the liquid detection sensor is controlled to start, so that the liquid detection sensor detects whether the electronic device is in contact with liquid, so that the fan can be turned on in time when the electronic device is in contact with liquid to prevent the liquid from dirtying the surface of the electronic device.

[0126] In some embodiments, the anti-splash method may further include: controlling a microphone of the electronic device to collect sound wave information; determining whether the sound wave information changes; and if the sound wave information changes, executing step S1100 to detect whether the electronic device is in contact with liquid.

[0127] In this embodiment, when the user has just put on the shoes, he or she usually walks on a road surface without liquid. If the sound wave information has not changed, it means that there is no liquid on the road surface and there is no risk of liquid on the road surface splashing onto the shoe surface. Therefore, there is no need to detect whether the shoes are in contact with liquid, and the liquid detection sensor may not work to reduce the power consumption of the shoes.

[0128] Specifically, the liquid detection sensor does not work because the power supply does not supply power to the liquid detection sensor, or because the controller stops outputting an enable signal to the liquid detection sensor.

[0129] In this embodiment, if the sound wave information changes, indicating that the road environment has changed and liquid may appear on the road surface, then the liquid detection sensor can be controlled to start, so that the liquid detection sensor can detect whether the shoes are in contact with liquid, so that the fan can be turned on in time when the shoes are in contact with liquid to prevent the liquid from dirtying the shoe surface.

[0130] Specifically, the liquid detection sensor is started by the power supply supplying power to the liquid detection sensor, or by the controller outputting an enable signal to the liquid detection sensor.

[0131] In some embodiments, the electronic device is a shoe. Then, when the sound wave information changes, step S1100 is executed, including: when the sound wave information changes, determining whether the road surface type of the road surface where the shoe is located is the target type; when the road surface type is the target type, detecting whether the shoe is in contact with liquid.

[0132] In this embodiment, the road surface type can include a splash-prone type and a non-splash-prone type, and the target type can be a splash-prone type. The splash-prone type refers to a road surface type that easily causes liquids to splash, including wet or waterlogged asphalt roads, wet or waterlogged cement roads, muddy roads, and roads after melting ice and snow. The non-splash-prone type refers to a road surface type that does not easily cause liquids to splash, including permeable roads, anti-skid roads, porous asphalt roads, rubber roads, etc.

[0133] In some embodiments, the shoe may be provided with a camera. Then, determining whether the road surface type of the shoe is the target type includes: photographing the road surface on which the shoe is located, and identifying whether the road surface type is the target type based on the photographed image.

[0134] In some embodiments, the shoe is not provided with a camera. Then, determining whether the road surface type of the road surface on which the shoe is located is the target type includes: sending a shooting request to a shooting device that establishes a communication connection with the shoe, receiving an identification result of whether the road surface type is the target type returned by the shooting device in response to the shooting request; and determining whether the road surface type is the target type based on the identification result.

[0135] The photographing device may respond to a photographing request, photograph the road surface on which the shoes are located, and identify whether the road surface type is a target type based on the photographed image.

[0136] In this embodiment, the shooting device can be an electronic product with a camera, such as a mobile phone, headphones, or AR glasses.

[0137] Furthermore, the photographing device may establish a communication connection with the communication module and perform data exchange via Wi-Fi, UWB (Ultra Wide Band), Bluetooth, LTE (Long Term Evolution), or the like.

[0138] Furthermore, the photographing device may perform recognition processing on the photographed image based on a pre-trained machine learning model to obtain a recognition result of whether the road surface type is the target type.

[0139] When the road surface type is not the target type, the shoe moves on the road surface and the liquid on the road surface will not splash onto the shoe surface. Therefore, there is no need to detect whether the shoe is in contact with the liquid, and the liquid detection sensor may not work to reduce the power consumption of the shoe.

[0140] When the road surface type is the target type, the shoes move on the road surface and the liquid on the road surface may splash onto the shoe surface. Then, the liquid detection sensor can be controlled to start, so that the liquid detection sensor detects whether the shoes are in contact with liquid, so that the fan can be turned on in time when the shoes are in contact with liquid to prevent the liquid from dirtying the shoe surface.

[0141] In some embodiments, the anti-splash method further includes: when the road surface type is not the target type, continuing to perform the steps of collecting sound wave information and determining whether the sound wave information has changed.

[0142] In some embodiments, the anti-splash method further includes: detecting whether the electronic device is moving; and when the movement of the electronic device is detected, executing the step of detecting whether the electronic device is in contact with liquid.

[0143] In some embodiments, the electronic device may include an acceleration sensor and a first processing unit, the acceleration sensor is used to collect acceleration data of the electronic device, and the first processing unit is used to detect whether the electronic device moves based on the acceleration data.

[0144] In this embodiment, the first processing unit may determine that the electronic device has moved if the acceleration of the electronic device is determined to be greater than or equal to a second threshold value based on the acceleration data. The second threshold value may be an acceleration value pre-set based on an application scenario or specific needs, for example, the second threshold value may be zero.

[0145] Furthermore, the first processing unit may determine the movement displacement of the electronic device based on the acceleration data of the electronic device, and determine that the electronic device has moved if the movement displacement is greater than or equal to a third threshold. The third threshold may be a displacement pre-set based on an application scenario or specific needs, for example, the third threshold may be 1 meter.

[0146] In some embodiments, the electronic device is a shoe. Then, the electronic device may include a pressure sensor and a second processing unit. The pressure sensor is used to collect pressure data on the shoe, and the second processing unit is used to detect whether the shoe moves based on the pressure data.

[0147] In this embodiment, the user needs to apply pressure to the shoes when wearing the shoes and moving. Therefore, the second processing unit can detect whether the shoes are moving based on the pressure data.

[0148] In one example, the second processing unit may determine that the shoe is moving if it is determined based on the pressure data that the pressure on the shoe is greater than or equal to a fourth threshold. The fourth threshold may be a pressure pre-set based on an application scenario or specific needs, for example, the fourth threshold may be 600N.

[0149] In another example, the second processing unit may determine the change between the maximum and minimum pressures applied to the shoe within a statistical period based on the pressure data, and determine that the shoe has moved if the change is greater than or equal to a fifth threshold. The duration of the statistical period may be a predetermined duration based on an application scenario or specific needs, for example, 3 seconds. The fifth threshold may be a predetermined pressure based on an application scenario or specific needs, for example, 600N.

[0150] Through the embodiments of the present disclosure, it is possible to accurately detect whether the shoe is moving.

[0151] In this embodiment, the first processing unit, the second processing unit, and the control module may be provided by the same processor or by different processors, which is not limited here.

[0152] In some embodiments, the microphone can be activated when the motion detection sensor detects movement of the electronic device.
