Description

Technical Field

[0001] The present application relates to the field of oral care technology, and in particular to a touch method, device, oral care equipment and storage medium. Background Art

[0002] Most of the buttons of personal care products such as electric toothbrushes use pressure buttons, which are triggered only by judging whether the pressure reaches the threshold. Such buttons are easily triggered by foreign objects. In order to solve this problem, a capacitance detection function is set in the buttons of oral care devices such as electric toothbrushes. The button is triggered only when both the pressure and capacitance reach the trigger threshold. This can effectively prevent false triggering caused by non-human pressing of the button.

[0003] However, such buttons often fail to trigger, and have a high failure rate, which affects the user experience. Summary of the invention

[0004] The embodiments of the present application disclose a touch method, device, oral care equipment and storage medium, which can reduce the key failure rate of the oral care equipment, improve the operation accuracy and enhance the user experience.

[0005] The embodiment of the present application discloses a touch control method, which is applied to an oral care device. The oral care device includes a touch control module, and the touch control module includes a capacitive sensor and a pressure sensor. The method includes:

[0006] Acquiring a capacitance signal collected by the capacitance sensor;

[0007] If the capacitance signal collected by the capacitance sensor is smaller than the first target capacitance, the trigger condition corresponding to the touch module is switched from the first trigger condition to the second trigger condition; the second capacitance threshold corresponding to the second trigger condition is smaller than the first capacitance threshold corresponding to the first trigger condition, and / or the second pressure threshold corresponding to the second trigger condition is greater than the first pressure threshold corresponding to the first trigger condition;

[0008] Acquiring a pressure signal collected by the pressure sensor;

[0009] If the capacitance signal and the pressure signal collected by the capacitance sensor meet the second trigger condition, the operation corresponding to the touch module is executed.

[0010] In this embodiment, the oral care device obtains a capacitance signal collected by the capacitance sensor. If the capacitance signal collected by the capacitance sensor is less than the first target capacitance, the trigger condition corresponding to the touch module is switched from the first trigger condition to the second trigger condition. The second capacitance threshold corresponding to the second trigger condition is less than the first capacitance threshold corresponding to the first trigger condition, and / or the second pressure threshold corresponding to the second trigger condition is greater than the first pressure threshold corresponding to the first trigger condition. The oral care device obtains a pressure signal collected by the pressure sensor, and when the capacitance signal and the pressure signal collected by the capacitance sensor meet the second trigger condition, the operation corresponding to the touch module is performed. The oral care device can switch the trigger condition corresponding to the touch module to the second trigger condition with a lower capacitance threshold and / or a higher pressure threshold when the capacitance signal collected by the capacitance sensor is small, that is, when the sensitivity of the capacitance sensor decreases, so that when the capacitance sensor detects a smaller capacitance signal, and / or only considers the pressure signal collected by the pressure sensor, even if the sensitivity of the capacitance sensor decreases, the trigger operation performed by the user can meet the second trigger condition, and the touch module is triggered, thereby reducing the failure rate of the touch module, improving the operation accuracy, and improving the user experience.

[0011] At the same time, since the pressure threshold is increased, the phenomenon of the touch module being falsely triggered due to collision between other objects and the touch module can be reduced, thereby reducing the false trigger rate of the touch module.

[0012] As an optional implementation manner, the first trigger condition is that the capacitance signal is greater than a first capacitance threshold, and the pressure signal is greater than a first pressure threshold;

[0013] The second trigger condition is that the pressure signal is greater than a second pressure threshold, and the second pressure threshold is greater than the first pressure threshold, or the second trigger condition is that the capacitance signal is greater than the second capacitance threshold and the pressure signal is greater than a third pressure threshold, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is greater than or equal to the first pressure threshold.

[0014] In this embodiment, the second trigger condition includes only high pressure trigger, or low capacitance and pressure trigger, that is, the second trigger condition does not take whether the capacitance signal reaches the capacitance threshold as a trigger condition, or lowers the capacitance threshold while considering the pressure threshold, so that when the sensitivity of the capacitance sensor decreases, the touch module can still be triggered, thereby reducing the failure rate of the touch module, improving operation accuracy, and improving user experience.

[0015] As an optional implementation manner, switching the trigger condition corresponding to the touch module from the first trigger condition to the second trigger condition includes:

[0016] determining a target operating state of the oral care device;

[0017] The trigger condition corresponding to the touch module is switched from the first trigger condition to a second trigger condition matching the target working state.

[0018] In this embodiment, since the probability of false triggering is different in different working states, different trigger conditions can be set for different operating states. In this embodiment, the oral care device switches the trigger condition corresponding to the touch module from a first trigger condition to a second trigger condition matching the target working state according to the target working state of the oral care device, thereby reducing the failure rate of the touch module and reducing the probability of false triggering of the touch module.

[0019] As an optional implementation, the target working state includes a running state;

[0020] The second trigger condition for matching the target working state is that the pressure signal is greater than a second pressure threshold; and / or,

[0021] The second trigger condition for matching the target working state is that the capacitance signal is greater than the second capacitance threshold and the pressure signal is greater than the third pressure threshold, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is equal to the first pressure threshold.

[0022] In this embodiment, the second trigger condition for running state matching is set as the pressure signal being greater than the second pressure threshold to meet the user's habits. At the same time, increasing the pressure threshold can reduce the probability of false triggering of the touch module.

[0023] The second trigger condition for matching the running state is set to that the capacitance signal is greater than the second capacitance threshold and the pressure signal is greater than the third pressure threshold. By lowering the capacitance threshold and maintaining the voltage threshold, the user can trigger the touch module by pressing it normally, thereby improving the user experience. At the same time, since the capacitance threshold is retained, the phenomenon of non-conductive objects hitting the touch module, causing the touch module to be triggered, can be avoided, thereby reducing the false trigger rate of the touch module.

[0024] As an optional implementation, the target working state includes a standby state;

[0025] The second trigger condition for matching the target working state is that the capacitance signal is greater than the second capacitance threshold, and the pressure signal is greater than the third pressure threshold, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is greater than the first pressure threshold.

[0026] In this embodiment, the second trigger condition corresponding to the standby state still considers the capacitance signal. By setting a lower capacitance threshold, it can play a certain anti-false touch function. At the same time, the voltage threshold is also set higher, which can further reduce the probability of false touch. At the same time, when the touch module is covered with stains, the user can trigger the touch module with greater pressing force, which can reduce the failure rate of the touch module and improve the user experience.

[0027] As an optional implementation, the method further includes:

[0028] When the capacitance signal collected by the capacitance sensor is less than the first target capacitance, a first prompt message is output; the first prompt message is used to prompt that the sensitivity of the capacitance sensor decreases, and / or to prompt a solution strategy for the decrease in the sensitivity of the capacitance sensor.

[0029] In this embodiment, when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, the oral care device outputs a first prompt message. That is, when the sensitivity of the capacitance sensor decreases, the device promptly feeds back to the user that the sensitivity of the capacitance sensor of the touch module has decreased, thereby improving the user experience.

[0030] As an optional implementation manner, when the capacitance signal collected by the capacitance sensor is smaller than the first target capacitance, outputting the first prompt information includes:

[0031] When the capacitance signal collected by the capacitance sensor is smaller than the first target capacitance, and the capacitance signal collected by the capacitance sensor and the pressure signal satisfy the second trigger condition, the first prompt information is output.

[0032] In this embodiment, the oral care device outputs the first prompt information only when the capacitance signal collected by the capacitance sensor and the pressure signal collected by the pressure sensor meet the second trigger condition. This allows the device to output abnormal prompt information only when the user presses the touch module, thereby avoiding resource consumption caused by frequent prompts while ensuring that the user can receive the reminder.

[0033] As an optional implementation, the first prompt information includes cleaning prompt information;

[0034] When the capacitance signal collected by the capacitance sensor is smaller than the first target capacitance, outputting first prompt information includes:

[0035] When the capacitance signal collected by the capacitance sensor is smaller than the first target capacitance, the cleaning prompt information is output, where the cleaning prompt information is used to prompt the touch module to be cleaned.

[0036] In this embodiment, when the sensitivity of the capacitive sensor of the oral care device decreases, the oral care device prompts the user to clean the touch module so that the user can clean the non-conductive material attached to the surface of the touch module, thereby reducing the maintenance cost of the oral cleaning device and restoring the sensitivity of the capacitive sensor, thereby improving the user experience.

[0037] As an optional implementation, the method further includes:

[0038] If the capacitance signal is greater than the second target capacitance, or equal to zero, the trigger condition corresponding to the touch module is switched from the first trigger condition to the third trigger condition, and the third trigger condition is that the pressure signal collected by the pressure sensor is greater than the first pressure threshold, and the second target capacitance is greater than the first target capacitance.

[0039] In this embodiment, the third trigger condition does not consider the capacitance signal collected by the capacitance sensor. When the capacitance sensor fails, the trigger condition corresponding to the touch module is switched to the third trigger condition to achieve pure pressure triggering, so that even when the capacitance sensor fails, the operation corresponding to the touch module can be performed when the pressure signal collected by the pressure sensor is greater than the first pressure threshold. At the same time, the pressure threshold corresponding to the third trigger condition is consistent with the pressure threshold corresponding to the first trigger condition when the capacitance sensor is normal, which conforms to the user's usage habits and improves the user experience.

[0040] As an optional implementation, the method further includes:

[0041] When the capacitance signal is greater than the second target capacitance, or equal to zero, a second prompt message is output; the second prompt message is used to prompt that the capacitance sensor has failed, and / or to prompt a solution strategy for the failure of the capacitance sensor.

[0042] In this embodiment, the oral care device outputs a second prompt message when the capacitance signal collected by the capacitance sensor is greater than the second target capacitance, or equal to zero. That is, when the capacitance sensor fails, the user is promptly fed back that the capacitance sensor of the touch module has failed, thereby improving the user experience.

[0043] As an optional implementation, the oral care device further includes other touch modules; the method further includes:

[0044] When the capacitance signal collected by the capacitance sensor in the touch module is smaller than the first target capacitance, in response to satisfying the fourth trigger condition corresponding to the other touch modules, outputting selection prompt information, wherein the selection prompt information is used to instruct the user to select to execute the operation corresponding to the touch module or to execute the operation corresponding to the other touch modules;

[0045] In response to the target selection operation, an operation corresponding to the target touch module corresponding to the target selection operation is executed.

[0046] In this embodiment, when the oral care device has multiple touch modules, if the capacitance signal collected by the capacitance sensor of one of the touch modules is smaller than the first target capacitance, that is, the sensitivity of the capacitance sensor of one of the touch modules decreases, then another touch module is used to trigger the function corresponding to the touch module, so that the oral care device executes the operation corresponding to the touch module, thereby improving the flexibility of the oral care device.

[0047] As an optional implementation, the method further includes:

[0048] Determine a change value corresponding to the capacitance signal collected by the capacitance sensor;

[0049] When the capacitance signal collected by the capacitance sensor is greater than or equal to the first target capacitance, if the change value is greater than the change threshold and the pressure signal collected by the pressure sensor is less than the preset pressure, the first capacitance threshold corresponding to the first trigger condition is increased.

[0050] In this embodiment, when the collected capacitance signal is greater than or equal to the first target capacitance, that is, when the capacitance sensor has no sensitivity, if it is detected that the change value corresponding to the capacitance signal collected by the capacitance sensor is greater than the change threshold, that is, when it is determined that a conductive material is attached to the surface of the touch module, the first capacitance threshold corresponding to the first trigger condition is increased to avoid triggering the touch module when the user does not press the touch module due to the influence of the conductive material, thereby reducing the false trigger rate of the touch module.

[0051] As an optional implementation, the method further includes:

[0052] Determine a target pressure interval to which the pressure signal collected by the pressure sensor belongs;

[0053] The executing the operation corresponding to the touch module includes:

[0054] An operation corresponding to the touch module and the target pressure range is performed.

[0055] In this embodiment, the oral care device determines the target pressure interval to which the pressure signal collected by the pressure sensor belongs. If the capacitance signal and pressure signal collected by the capacitance sensor meet the triggering conditions corresponding to the touch module, the operation corresponding to the touch module and the target pressure interval is performed, so that the oral care device can perform the operation matched with the user, thereby improving the intelligence of the oral care device.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0077] In the related technical solution, when the electric toothbrush determines that the capacitance value collected by the capacitance sensor of the button and the pressure value collected by the pressure sensor of the button meet the normal mode threshold, the button is triggered.

[0078] However, in actual applications, abnormal capacitance often occurs, resulting in the inability to trigger the key when the user presses it. For example, when the surface of the key is covered with toothpaste stains or other non-conductive objects, when the user presses the key, the capacitance value detected by the capacitive sensor of the key is difficult to meet the normal mode threshold, resulting in the key being unable to be triggered, that is, the key is invalid.

[0079] The embodiments of the present application disclose a touch method, device, oral care equipment and storage medium, which can reduce the key failure rate of the oral care equipment, improve the operation accuracy and enhance the user experience.

[0080] Figure 1 FIG. 1 shows an application scenario diagram of a touch control method provided by an embodiment of the present application. Figure 1 As shown, the oral care device 110 may include at least one touch module 111. Exemplarily, the oral care device 110 may include but is not limited to an electric toothbrush, a water flosser, and a tooth stick.

[0081] In some embodiments, please refer to Figure 1 The oral care device 110 can be communicatively connected with the terminal device 120, and the oral care device 110 can send prompt information to the terminal device 120 so that the terminal device 120 displays the prompt information, and the prompt information may include first prompt information and second prompt information.

[0082] In other embodiments, please continue to refer to Figure 1 The oral care device 110 may include a display screen 112 , and the oral care device 110 may display prompt information through the display screen 112 .

[0083] Figure 2 The structure diagram of the oral care device provided in the embodiment of the present application is shown. Figure 2 As shown, each touch module 210 may include a capacitive sensor 211 and a pressure sensor 212. The capacitive sensor 211 is used to collect capacitive signals.

When the touch module 210 is subjected to pressure, the pressure signal collected by the pressure sensor 212 will change.

[0084] Please continue to refer to Figure 2 The oral care device 200 may further include an MCU (Microcontroller Unit) 220, which is connected to the capacitive sensor 211 and the pressure sensor 212 respectively. The MCU 220 can obtain the capacitive signal collected by the capacitive sensor 211 and the pressure signal collected by the pressure sensor 212.

[0085] Please refer to Figure 3 , which shows a schematic flow diagram of a touch control method provided in an embodiment of the present application, the method can be applied to an oral care device, the oral care device may include a touch control module, the touch control module may include a capacitive sensor and a pressure sensor. The touch control module is any touch control module in the oral care device.

[0086] like Figure 3 As shown, the method includes steps 302 to 314.

[0087] Step 302: Acquire a capacitance signal collected by a capacitance sensor.

[0088] It should be noted that when a conductive material enters the electric field of the capacitive sensor, the capacitive signal collected by the capacitive sensor will change. According to the capacitive signal collected by the capacitive sensor, it can be determined whether the capacitive sensor is normal and whether there is a conductive object (such as a finger) close to the touch module.

[0089] In some embodiments, the capacitive sensor may continuously acquire a capacitive signal.

[0090] In some embodiments, the oral care device can determine the start acquisition time of the capacitive sensor based on multiple historical operating times. It should be noted that the historical operating time may refer to the time when the oral care device enters the operating state. The user generally uses the oral care device in a specific time period. Therefore, the time to obtain the capacitive signal collected by the capacitive sensor can be determined according to the time when the user uses the oral care device, thereby reducing unnecessary acquisition and processing burdens, while ensuring that the trigger condition corresponding to the touch module can be determined in time. Exemplarily, the start acquisition time is the average value between multiple historical operating times and the difference between the preset time period. For example, the average value between multiple historical operating times is 8 points, and the preset time period is 2 hours, then the start acquisition time of the capacitive sensor is 6 points. The capacitive sensor can continue to collect at 6 points until the preset time is reached, such as 10 points.

[0091] Step 304 , determining whether the capacitance signal collected by the capacitance sensor is less than the first target capacitance, if not, executing step 306 , and steps 310 to 312 , and if yes, executing steps 308 to 310 , and step 314 .

[0092] It should be noted that the abnormality of the capacitive sensor may refer to the inability of the capacitive signal collected by the capacitive sensor to reflect the actual situation. The abnormality of the capacitive sensor may include a decrease in the sensitivity of the capacitive sensor or a failure of the capacitive sensor. The failure of the capacitive sensor may include but is not limited to the electrostatic breakdown of the capacitive sensor, or the open circuit of the capacitive sensor related circuit, or the short circuit of the capacitive sensor related circuit. When the capacitive sensor fails, the capacitive signal collected by the capacitive sensor is zero, or the capacitive signal collected by the capacitive sensor is higher than the normal value. The decrease in the sensitivity of the capacitive sensor may refer to a decrease in the amplitude of the change of the capacitive signal collected by the capacitive sensor, such as when the surface of the capacitive sensor is covered with non-conductive stains, the amplitude of the change of the capacitive signal collected by the capacitive sensor decreases.

[0093] It should be noted that the first target capacitance can be used to measure whether the sensitivity of the capacitive sensor decreases. Exemplarily, the first target capacitance is less than or equal to the first capacitance threshold corresponding to the first trigger condition. If the capacitance signal collected by the capacitive sensor is less than or equal to the first target capacitance, it can be determined that the sensitivity of the capacitive sensor has decreased. If the capacitance signal collected by the capacitive sensor is greater than or equal to the first target capacitance, it can be determined that the sensitivity of the capacitive sensor has not decreased.

[0094] Exemplarily, the first target capacitance is less than or equal to the first capacitance threshold corresponding to the first trigger condition, and is greater than 0. When the sensitivity of the touch module is normal and the user presses the touch module, the capacitance signal collected by the capacitance sensor will be greater than the first capacitance threshold. Therefore, if the capacitance signal collected by the capacitance sensor is less than the first target capacitance, it can be considered that the sensitivity of the capacitance sensor is reduced.

[0095] In some embodiments, when it is determined that the voltage signal collected by the voltage sensor is greater than or equal to the first pressure threshold corresponding to the first trigger condition, and the capacitance signal collected by the capacitance sensor is less than the first target capacitance, the trigger condition corresponding to the touch module is switched from the first trigger condition to the second trigger condition. It should be noted that when the user does not press the capacitance sensor, the capacitance signal collected by the capacitance sensor may be small. In this case, even if the capacitance sensor is normal, the capacitance signal collected by the capacitance sensor is relatively small. Therefore, when it is determined that the voltage signal collected by the voltage sensor is greater than or equal to the first pressure threshold, and the capacitance signal collected by the capacitance sensor is less than the first target capacitance, the trigger condition corresponding to the touch module is switched from the first trigger condition to the second trigger condition, which can reduce the phenomenon that the capacitance sensor is considered to have decreased sensitivity because the user does not press the touch module even though the sensitivity of the capacitance sensor has not decreased, thereby improving the accuracy of the trigger condition switching and thus improving the accuracy of the operation.

[0096] The oral care device can determine whether the pressure signal collected by the pressure sensor is greater than or equal to the first pressure threshold before determining whether the capacitance signal collected by the capacitance sensor is less than the first target capacitance. If it is determined that the pressure signal is greater than or equal to the first pressure threshold, it can be determined whether the capacitance signal collected by the capacitance sensor is less than the first target capacitance. If it is determined that the capacitance signal collected by the capacitance sensor is less than the first target capacitance, it can be considered that when the user presses the touch module, the capacitance signal collected by the capacitance sensor is small, and the capacitance sensor has a decreased sensitivity. If it is determined that the pressure signal is greater than or equal to the first pressure threshold, and the capacitance signal is greater than the first target capacitance, it can be determined that the capacitance sensor has no decreased sensitivity.

[0097] Step 306: determine the trigger condition corresponding to the touch module as the first trigger condition.

[0098] It should be noted that if there is no abnormality in the capacitive sensor, that is, the capacitive sensor is normal, the trigger condition corresponding to the touch module is determined to be the first trigger condition. Among them, the first trigger condition has high requirements for capacitive triggering, which can effectively prevent false triggering caused by non-human pressing of buttons and improve the accuracy of operation. Exemplarily, the first trigger condition can be determined based on the pressure signal collected by the pressure sensor and the capacitance signal collected by the capacitive sensor when the user presses the touch module when the capacitive sensor is normal.

[0099] In some embodiments, the first trigger condition is that the capacitance signal is greater than the first capacitance threshold, and the pressure signal is greater than the first pressure threshold. It should be noted that the first capacitance threshold can be used to measure whether the capacitance signal collected by the capacitance sensor reaches the capacitance signal when the user presses the touch module, and the first pressure threshold can be used to measure whether the pressure signal collected by the pressure sensor reaches the voltage signal when the user presses the touch module. Exemplarily, the first capacitance threshold can be the minimum value of the capacitance signal collected by the capacitance sensor when the capacitance sensor is normal and the user's finger presses the touch module, and the first pressure threshold can be used to measure the minimum value of the voltage signal collected by the voltage sensor when the user's finger presses the touch module. Among them, the first capacitance threshold and the first pressure threshold can be measured according to experiments. Exemplarily, the range corresponding to the first capacitance threshold includes 450uF (microfarad) to 550uF. Optionally, the first capacitance threshold can be 450uF, 500uF or 550uF. Exemplarily, the range corresponding to the first voltage threshold includes 1.46N (Newton) to 2.46N. Optionally, the first capacitance threshold may be 1.46N, 1.96N or 2.46N.

[0100] Step 308: Switch the trigger condition corresponding to the touch module from the first trigger condition to the second trigger condition.

[0101] Among them, the second capacitance threshold corresponding to the second trigger condition is less than the first capacitance threshold corresponding to the first trigger condition, and / or the second pressure threshold corresponding to the second trigger condition is greater than the first pressure threshold corresponding to the first trigger condition. It should be noted that when the oral care device determines that the sensitivity of the capacitance sensor decreases, it switches the trigger condition corresponding to the touch module to the second trigger condition with a smaller capacitance threshold, and / or switches to the second trigger condition with a higher pressure threshold. By lowering the capacitance threshold, the failure of the touch module due to the decrease in the sensitivity of the capacitance sensor is avoided, that is, the failure rate of the key of the oral care device is reduced, the operation accuracy is improved, and the user experience is improved. At the same time, by increasing the pressure threshold, even if the capacitance signal reaches the capacitance threshold as the trigger condition of the touch module, the phenomenon of false triggering caused by other objects colliding with the touch module can be reduced, the operation accuracy is improved, and the user experience is improved.

[0102] In some embodiments, the second trigger condition is that the pressure signal is greater than the second pressure threshold, or the second trigger condition is that the capacitance signal is greater than the second capacitance threshold, and the pressure signal is greater than a third pressure threshold, wherein the second pressure threshold is greater than the first pressure threshold, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is greater than or equal to the first pressure threshold.

[0103] It should be noted that if the second trigger condition is that the pressure signal is greater than the second pressure threshold, it can be considered that the capacitance signals collected by the capacitance sensor meet the second trigger condition, or the size of the capacitance signal has no effect on determining whether the second trigger condition is met.

[0104] It should be noted that the second trigger condition includes only high pressure trigger, or low capacitance and pressure trigger, that is, the second trigger condition does not take whether the capacitance signal reaches the capacitance threshold as a trigger condition, or lowers the capacitance threshold while considering the pressure threshold, so that when the sensitivity of the capacitance sensor decreases, the touch module can still be triggered, thereby reducing the failure rate of the touch module, improving operation accuracy, and improving user experience.

[0105] Step 310: Acquire a pressure signal collected by a pressure sensor.

[0106] Step 312: If the capacitance signal and the pressure signal collected by the capacitance sensor meet the first trigger condition, the corresponding operation of the touch module is executed.

[0107] It should be noted that the operation corresponding to the touch module may refer to the operation that the oral care device needs to perform when the touch module is triggered, such as performing oral care, testing the oral cavity, etc. For example, taking the oral care device including an electric toothbrush as an example, performing the operation corresponding to the touch module includes controlling the motor movement of the electric toothbrush to drive the brush head to move, thereby cleaning the oral cavity.

[0108] It can be understood that when the capacitance signal collected by the capacitance sensor is greater than or equal to the first target capacitance, that is, the capacitance sensor does not show a decrease in sensitivity, if the capacitance signal and pressure signal collected by the capacitance sensor meet the first trigger condition, it is considered that the touch module is pressed, and the oral care device performs the operation corresponding to the touch module; if the capacitance signal and pressure signal collected by the capacitance sensor do not meet the first trigger condition, it is considered that the touch module is not pressed, and the oral care device does not perform the operation corresponding to the touch module, thereby improving the accuracy of the operation.

[0109] Step 314: If the capacitance signal and the pressure signal collected by the capacitance sensor meet the second trigger condition, the corresponding operation of the touch module is executed.

[0110] It should be noted that when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, that is, the capacitance sensor has a decreased sensitivity, if the capacitance signal and pressure signal collected by the capacitance sensor meet the second trigger condition, the operation corresponding to the touch module is executed; if the capacitance signal and pressure signal collected by the capacitance sensor do not meet the second trigger condition, the operation corresponding to the touch module is not executed. When the capacitance sensor has a decreased sensitivity, by switching to the second trigger condition, that is, lowering the capacitance threshold, or, without considering the capacitance threshold, increasing the pressure threshold, even when the capacitance sensor has a decreased sensitivity, the user can still trigger the touch module to control the oral care device to execute the operation corresponding to the touch module to reduce the failure rate. At the same time, without considering the capacitance threshold, the pressure threshold is increased to reduce the false touch phenomenon.

[0111] In an embodiment of the present application, the oral care device obtains a capacitance signal collected by a capacitance sensor. If the capacitance signal collected by the capacitance sensor is less than the first target capacitance, the trigger condition corresponding to the touch module is switched from the first trigger condition to the second trigger condition. The second capacitance threshold corresponding to the second trigger condition is less than the first capacitance threshold corresponding to the first trigger condition, and / or the second pressure threshold corresponding to the second trigger condition is greater than the first pressure threshold corresponding to the first trigger condition. The oral care device obtains a pressure signal collected by the pressure sensor, and when the capacitance signal and the pressure signal collected by the capacitance sensor meet the second trigger condition, the operation corresponding to the touch module is performed. The oral care device can switch the trigger condition corresponding to the touch module to the second trigger condition with a lower capacitance threshold and / or a higher pressure threshold when the capacitance signal collected by the capacitance sensor is small, that is, when the capacitance sensor has a decreased sensitivity, so that when the capacitance sensor detects a smaller capacitance signal, and / or only considers the pressure signal collected by the pressure sensor, even if the capacitance sensor has a decreased sensitivity, the trigger operation performed by the user can meet the second trigger condition, thereby triggering the touch module, reducing the failure rate of the touch module, improving the operation accuracy, and improving the user experience.

[0112] At the same time, since the pressure threshold is increased, the phenomenon of the touch module being falsely triggered due to collision between other objects and the touch module can be reduced, thereby reducing the false trigger rate of the touch module.

[0113] Please refer to Figure 4 , which shows a schematic diagram of a switching process provided by an embodiment of the present application, such as Figure 4 As shown, switching the trigger condition corresponding to the touch module from the first trigger condition to the second trigger condition may include steps 402 to 404.

[0114] Step 402, determining a target working state of the oral care device.

[0115] Step 404: Switch the trigger condition corresponding to the touch module from the first trigger condition to a second trigger condition matching the target working state.

[0116] It should be noted that the target working state may refer to the working state of the oral care device. The target working state may include an operating state or a standby state. Among them, the operating state may refer to the state in which the oral care device is in the process of performing its main function, such as oral care. The standby state may refer to the state in which the oral care device is not performing its main function. In the standby state, the oral care device maintains a certain degree of preparation or monitoring function and can quickly respond to user input. For example, in the standby state, the oral care device can obtain at least one of a capacitance signal collected by a capacitance sensor and a pressure signal collected by a pressure sensor.

[0117] It should be noted that when the oral care device is in operation and the user is using the oral care device, the probability of the touch module being hit by foreign objects is very low, while when the oral care device is not in operation, that is, in standby mode, the probability of the touch module being hit by foreign objects is relatively high. Due to different operating states, the probability of false triggering is different, so different trigger conditions can be set for different operating states. In this embodiment, the oral care device switches the trigger condition corresponding to the touch module from the first trigger condition to the second trigger condition matching the target operating state according to the target operating state of the oral care device, thereby reducing the failure rate of the touch module and reducing the probability of false triggering of the touch module.

[0118] In some embodiments, the target working state includes an operating state, and the second trigger condition matched by the target working state is that the pressure signal is greater than a second pressure threshold; wherein the second pressure threshold is greater than the first pressure threshold. It should be noted that after pressing the touch module, if the user finds that the touch module cannot be triggered, the user will instinctively try to increase the pressing force to trigger it. Therefore, the second trigger condition matched by the operating state is set to that the pressure signal is greater than the second pressure threshold to meet the user's habits. At the same time, increasing the pressure threshold can reduce the probability of false triggering of the touch module.

[0119] In some embodiments, the target working state includes an operating state, and the second trigger condition matched by the target working state is that the capacitance signal is greater than the second capacitance threshold, and the pressure signal is greater than the third pressure threshold. Among them, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is equal to the first pressure threshold. It should be noted that after determining that the touch module is abnormal, by lowering the capacitance threshold and maintaining the voltage threshold, the user can trigger the touch module by pressing it normally, thereby improving the user experience. At the same time, since the capacitance threshold is retained, the phenomenon of non-conductive objects hitting the touch module, causing the touch module to be triggered, can be avoided, thereby reducing the false trigger rate of the touch module.

[0120] In some embodiments, the target working state includes a running state, and the second trigger condition matched by the target working state includes that the pressure signal is greater than the second pressure threshold, and the capacitance signal is greater than the second capacitance threshold, and the pressure signal is greater than the third pressure threshold. It should be noted that the pressure signal is greater than the second pressure threshold, or the capacitance signal is greater than the second capacitance threshold, and the pressure signal is greater than the third pressure threshold, both of which can trigger the touch module. In this embodiment, the second trigger condition includes multiple conditions, which helps to respond to the user's trigger operation more flexibly, thereby improving the user experience.

[0121] In some embodiments, the target working state includes a standby state, and the second trigger condition matched by the target working state is that the capacitance signal is greater than the second capacitance threshold, and the pressure signal is greater than the third pressure threshold. Among them, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is greater than the first pressure threshold. It should be noted that the standby state is the main scenario for preventing false touches. For example, when traveling on a business trip, the oral care device is placed in a bag, and other items in the bag may hit the touch module. If only the pressure signal is considered, the probability of false triggering of the touch module is very high. After pressing the touch module, if the user finds that the touch module cannot be triggered, the user will instinctively try to increase the pressing force to trigger it. In this embodiment, the second trigger condition corresponding to the standby state still considers the capacitance signal. By setting a lower capacitance threshold, it can play a certain anti-false touch function. At the same time, the voltage threshold set is also higher, which can further reduce the probability of false touches. At the same time, when the touch module is covered with stains, the user can trigger the touch module with a greater pressing force, which can reduce the failure rate of the touch module and improve the user experience.

[0122] Please refer to Figure 5 , which shows a schematic diagram of the process of another touch control method provided by an embodiment of the present application, such as Figure 5 As shown, the touch control method may include steps 502 to 520.

[0123] Step 502: Acquire a capacitance signal collected by a capacitance sensor.

[0124] Step 504 , determining whether the capacitance signal collected by the capacitance sensor is greater than the second target capacitance, or equal to zero; if so, executing step 506 and steps 514 to 516 ; if not, executing step 508 .

[0125] Among them, the second target capacitance is greater than the first target capacitance. The second target capacitance can be used to measure whether the capacitance signal collected by the capacitance sensor is an abnormally high value, that is, whether it is much higher than the capacitance signal that can be collected by the capacitance sensor when the capacitance sensor is normal and the user presses the capacitance sensor. In the case of failure of the capacitance sensor, the capacitance signal collected by the capacitance sensor will be greater than the second target capacitance, or equal to 0. If the capacitance sensor has problems such as breakdown or open circuit, the capacitance signal collected by the capacitance sensor may be greater than the second target capacitance. If the capacitance sensor has problems such as plate short circuit, the capacitance signal collected by the capacitance sensor may be 0. Therefore, when the capacitance signal collected by the capacitance signal is greater than the second target capacitance, or the capacitance signal is equal to zero, it can be considered that the capacitance sensor has failed. At this time, the capacitance signal collected by the capacitance sensor is completely unreliable. In this case, the trigger condition that only considers the pressure signal can be used as the trigger condition corresponding to the touch module, which can improve the accuracy of the operation and improve the user experience.

[0126] Step 506: switch the trigger condition corresponding to the touch module to the third trigger condition.

[0127] Among them, the third trigger condition is that the pressure signal collected by the pressure sensor is greater than the first pressure threshold. It should be noted that the third trigger condition does not take into account the capacitance signal collected by the capacitance sensor. In the case of failure of the capacitance sensor, the trigger condition corresponding to the touch module is switched to the third trigger condition to achieve pure pressure triggering, so that even in the case of failure of the capacitance sensor, the operation corresponding to the touch module can be performed when the pressure signal collected by the pressure sensor is greater than the first pressure threshold. At the same time, the pressure threshold corresponding to the third trigger condition is consistent with the pressure threshold corresponding to the first trigger condition when the capacitance sensor is normal, which conforms to the user's usage habits and improves the user experience.

[0128] When the third trigger condition is adopted, the trigger condition corresponding to the touch module is switched to the pure pressure mode, that is, the size of the capacitance signal does not need to be considered. In this embodiment, when the capacitance sensor fails, the user can meet the third trigger condition corresponding to the touch module by pressing the touch module normally, thereby triggering the touch module and reducing the failure rate of the touch module.

[0129] In some embodiments, it is determined whether the multiple capacitance signals continuously collected by the capacitance sensor are greater than the second target capacitance, or equal to zero. If so, step 506 and step 514 to step 516 are executed, and if not, step 508 is executed. In this embodiment, by determining whether the multiple capacitance signals continuously collected by the capacitance sensor are all greater than the second target capacitance, or whether the multiple capacitance signals continuously collected by the capacitance sensor are all equal to zero, it is determined whether the capacitance sensor is invalid, which can avoid misjudgment caused by capacitance signal fluctuations and improve the accuracy of failure judgment.

[0130] Step 508 , determining whether the capacitance signal collected by the capacitance sensor is less than the first target capacitance, if not, executing steps 510 , 514 , and 518 , and if so, executing steps 512 to 514 , and step 520 .

[0131] Step 510: determine the trigger condition corresponding to the touch module as the first trigger condition.

[0132] It should be noted that when the capacitance signal collected by the capacitance sensor is greater than or equal to the first target capacitance and less than or equal to the second target capacitance, it can be considered that the capacitance sensor has not failed and there is no sensitivity reduction. At this time, the trigger condition corresponding to the touch module can be determined as the first trigger condition. When the user presses the touch module, the capacitance signal collected by the capacitance sensor and the pressure signal collected by the pressure sensor meet the first trigger condition, thereby triggering the oral care device to execute the corresponding operation of the touch module.

[0133] Step 512: Switch the trigger condition corresponding to the touch module from the first trigger condition to the second trigger condition.

[0134] It should be noted that when the capacitance signal collected by the capacitance sensor is less than the first target capacitance and is not zero, it can be considered that the capacitance sensor has a decreased sensitivity, and the trigger condition corresponding to the touch module can be determined as the second trigger condition. Even though the capacitance signal collected by the capacitance sensor does not reach the first capacitance threshold when the user presses the touch module, it can also be achieved to trigger the oral care device to execute the corresponding operation of the touch module, thereby reducing the failure rate of the touch module.

[0135] Step 514: Acquire the pressure signal collected by the pressure sensor.

[0136] Step 516: If the pressure signal satisfies the third trigger condition, the corresponding operation of the touch module is executed.

[0137] Step 518: If the capacitance signal and the pressure signal collected by the capacitance sensor meet the first trigger condition, the corresponding operation of the touch module is executed.

[0138] Step 520: If the capacitance signal and the pressure signal collected by the capacitance sensor meet the second trigger condition, the corresponding operation of the touch module is executed.

[0139] In some embodiments, the oral care device outputs a prompt message when an abnormality occurs in the capacitive sensor.

[0140] Exemplarily, the prompt information is used to prompt that the capacitive sensor is abnormal. It should be noted that when the capacitive sensor is abnormal, the oral care device prompts that the capacitive sensor of the touch module is abnormal, so as to promptly remind the user of the abnormal situation.

[0141] Exemplarily, the abnormality prompt information is used to prompt the abnormality of the capacitive sensor. It should be noted that when the capacitive sensor of the oral care device is abnormal, it prompts the abnormality of the capacitive sensor of the touch module, so that the user can be informed of the abnormality and make correct intervention.

[0142] Exemplarily, the abnormality prompt information is used to prompt a solution strategy for the abnormality of the capacitive sensor. It should be noted that when the capacitive sensor of the oral care device has an abnormality, it prompts a solution strategy for the abnormality of the capacitive sensor, thereby guiding the user to perform the correct solution operation and improving the user experience.

[0143] In this embodiment, when an abnormality occurs in the capacitive sensor of the oral care device, the oral care device outputs a prompt message to promptly feedback the abnormality of the capacitive sensor of the touch module to the user, thereby improving the user experience.

[0144] In some embodiments, when the capacitance signal collected by the capacitance sensor is greater than the second target capacitance, or equal to zero, a second prompt message is output, wherein the second prompt message is used to indicate the failure of the capacitance sensor and / or a solution strategy for the failure of the capacitance sensor.

[0145] In some embodiments, the second prompt information includes replacement prompt information. When the capacitive sensor fails, the replacement prompt information is output, and the replacement prompt information is used to prompt the user to replace the capacitive sensor. It should be noted that when the capacitive sensor fails, the oral care device prompts the user to replace the capacitive sensor. By providing clear replacement instructions, the fault diagnosis time can be reduced and the user experience can be improved.

[0146] In some embodiments, when the capacitance signal collected by the capacitance sensor is greater than the second target capacitance, or equal to zero, and the pressure signal collected by the pressure sensor meets the third trigger condition, the second prompt information is output. It should be noted that the oral care device outputs the second prompt information only when the pressure signal collected by the pressure sensor meets the second trigger condition, so that the second prompt information is output only when the user presses the touch module, which can avoid resource consumption caused by frequent prompts. At the same time, since the pressure signal collected by the pressure sensor meets the third trigger condition, it indicates that the user is most likely using the oral care device at this time. Therefore, it can be guaranteed that the user can receive the reminder and the effectiveness of the reminder is guaranteed.

[0147] In this embodiment, the oral care device outputs a second prompt message when the capacitance signal collected by the capacitance sensor is greater than the second target capacitance, or equal to zero. That is, when the capacitance sensor fails, the user is promptly fed back that the capacitance sensor of the touch module has failed, thereby improving the user experience.

[0148] In some embodiments, when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, a first prompt message is output, wherein the first prompt message is used to prompt that the sensitivity of the capacitance sensor decreases and / or to prompt a solution strategy for the decrease in the sensitivity of the capacitance sensor.

[0149] In some embodiments, when the capacitance signal collected by the capacitance sensor is less than the first target capacitance and the capacitance signal is not zero, the first prompt information is output. It should be noted that when the capacitance signal collected by the capacitance sensor is zero, the capacitance sensor can be considered to be failed, and the capacitance sensor failure should be prompted.

[0150] In some embodiments, the first prompt information includes cleaning prompt information, and when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, the cleaning prompt information is output, wherein the cleaning prompt information is used to prompt the touch module to be cleaned. It should be noted that when the sensitivity of the capacitance sensor of the oral care device decreases, the oral care device prompts the user to clean the touch module, so that the user can clean the non-conductive material attached to the surface of the touch module, thereby reducing the maintenance cost of the oral cleaning device, and at the same time, the sensitivity of the capacitance sensor can be restored, thereby improving the user experience.

[0151] In some embodiments, when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, and the capacitance signal collected by the capacitance sensor and the pressure signal collected by the pressure sensor meet the second trigger condition, the first prompt information is output. It should be noted that the oral care device outputs the first prompt information only when the capacitance signal collected by the capacitance sensor and the pressure signal collected by the pressure sensor meet the second trigger condition, so that the abnormal prompt information is output only when the user presses the touch module, which can avoid resource consumption caused by frequent prompts and ensure that the user can receive the reminder.

[0152] In this embodiment, when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, the oral care device outputs a first prompt message. That is, when the sensitivity of the capacitance sensor decreases, the device promptly feeds back to the user that the sensitivity of the capacitance sensor of the touch module has decreased, thereby improving the user experience.

[0153] In some embodiments, the oral care device may include a display screen, and the oral care device displays prompt information through the display screen, and the prompt information includes first prompt information and second prompt information.

[0154] In other embodiments, the oral care device may be connected to the terminal device for communication, and the oral care device may send prompt information to the terminal device so that the prompt information is displayed by the terminal device. Optionally, the terminal device may include but is not limited to electronic devices such as mobile phones and smart wearable devices.

[0155] In some embodiments, the oral care device may include a touch module and other touch modules. When an abnormality occurs in the capacitive sensor in the touch module, the oral care device outputs selection prompt information in response to satisfying the fourth trigger condition corresponding to the other touch modules, and in response to the target selection operation, executes the operation corresponding to the target touch module corresponding to the target selection operation. The selection prompt information is used to prompt the user to select the operation corresponding to the touch module, or to execute the operation corresponding to the other touch modules.

[0156] It should be noted that other touch modules may include capacitive sensors and pressure sensors. The capacitive sensors of other touch modules are used to collect capacitive signals corresponding to the other touch modules, and the pressure sensors of other touch modules are used to collect pressure signals corresponding to the other touch modules. When a biological body approaches the other touch module, the capacitive signals collected by the capacitive sensors of the other touch modules will change. When the other touch modules are subjected to pressure, the pressure signals collected by the pressure sensors of the other touch modules will change. There is no abnormality in the capacitive sensors in the other touch modules, and the fourth trigger condition may refer to the trigger condition corresponding to the other touch modules. Exemplarily, the fourth trigger condition includes the trigger condition corresponding to the case where there is no abnormality in the capacitive sensors of the other touch modules. Exemplarily, the fourth trigger condition is that the capacitive signal is greater than the first capacitive threshold, and the pressure signal is greater than the first pressure threshold.

[0157] In some embodiments, the oral care device may send selection prompt information to the terminal device in response to satisfying the fourth trigger condition corresponding to the other touch modules, so that the selection prompt information is displayed through the terminal device. Figure 6 The selection prompt information displayed by the terminal device is shown. The selection prompt information includes prompt text content, a first control 610 corresponding to the touch module, and a second control 620 corresponding to other touch modules. The oral care device responds to the user's triggering operation on the target control and performs the operation corresponding to the target touch module corresponding to the target control. The target control includes the first control 610 or the second control 620. Optionally, the triggering operation may include but is not limited to single-click, double-click, and long press. When the user triggers the first control 610, the oral care device performs the operation corresponding to the touch module. When the user triggers the second control 620, the oral care device performs the operation corresponding to the other touch modules. Optionally, the prompt text content may include "Please confirm to execute the operation corresponding to the touch module, or execute the operation corresponding to other touch modules."

[0158] It should be noted that the selection prompt information can be displayed through a terminal device, and can also be displayed through a display screen of an oral care device, and this embodiment does not specifically limit this.

[0159] In this embodiment, when the oral care device has multiple touch modules, if the capacitance signal collected by the capacitance sensor of one of the touch modules is smaller than the first target capacitance, that is, the sensitivity of the capacitance sensor of one of the touch modules decreases, then another touch module is used to trigger the function corresponding to the touch module, so that the oral care device executes the operation corresponding to the touch module, thereby improving the flexibility of the oral care device.

[0160] It should be noted that the surface of the touch module is covered with conductive materials, such as water, which will cause the capacitance signal collected by the capacitance sensor to increase. In some embodiments, the change value corresponding to the capacitance signal collected by the capacitance sensor is determined. When the capacitance signal collected by the capacitance sensor is greater than or equal to the first target capacitance, if the change value is greater than the change threshold, and the pressure signal collected by the pressure sensor is less than the preset pressure, the first capacitance threshold corresponding to the first trigger condition is increased.

[0161] It should be noted that the preset pressure can be used to measure whether the user presses the touch module. If the pressure signal collected by the pressure sensor is less than the preset pressure, it means that the user does not press the touch module. If the pressure signal collected by the pressure sensor is greater than or equal to the preset pressure, it means that the user presses the touch module. Exemplarily, the preset pressure is consistent with the first voltage threshold. When the pressure signal collected by the pressure sensor is less than the preset pressure, and when the collected capacitance signal is greater than or equal to the first target capacitance (that is, it is considered that the capacitance sensor has not experienced a decrease in sensitivity), if the change value corresponding to the capacitance signal collected by the capacitance sensor is greater than the change threshold, it can be considered that there are other conductive objects causing the capacitance signal detected by the capacitance sensor to change (increase). In this case, by increasing the first capacitance threshold corresponding to the first trigger condition, it is avoided that the touch module is covered with conductive material, resulting in the touch module being triggered when the user does not press the first touch module, thereby reducing the false trigger rate of the touch module.

[0162] In some embodiments, the oral care device determines the change value corresponding to the capacitance signal collected by the capacitance sensor. When the capacitance signal collected by the capacitance sensor is greater than or equal to the first target capacitance and the capacitance signal is less than or equal to the second target capacitance, it is determined whether the change value is greater than the change threshold, and the pressure signal collected by the pressure sensor is less than the preset pressure. If the change value is greater than the change threshold, and the pressure signal collected by the pressure sensor is less than the preset pressure, the first capacitance threshold corresponding to the first trigger condition is increased. If the change value is less than or equal to the change threshold, or the pressure signal collected by the pressure sensor is greater than or equal to the preset pressure, the first capacitance threshold corresponding to the first trigger condition is maintained unchanged. It should be noted that when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, or the collected capacitance signal is greater than the second target capacitance (abnormality occurs), the capacitance signal collected by the capacitance sensor is unreliable, that is, the change value corresponding to the capacitance signal is inaccurately determined. The oral care device determines whether the change value is greater than the change threshold when the capacitance sensor is not abnormal, which can ensure the accuracy of the determined change value, thereby ensuring the accuracy of the judgment result and ensuring that the first capacitance threshold improves the reliability of the operation.

[0163] In this embodiment, when the collected capacitance signal is greater than or equal to the first target capacitance, that is, when the capacitance sensor has no sensitivity, if it is detected that the change value corresponding to the capacitance signal collected by the capacitance sensor is greater than the change threshold, that is, when it is determined that a conductive material is attached to the surface of the touch module, the first capacitance threshold corresponding to the first trigger condition is increased to avoid triggering the touch module when the user does not press the touch module due to the influence of the conductive material, thereby reducing the false trigger rate of the touch module.

[0164] In some embodiments, the oral care device determines the target pressure interval to which the pressure signal collected by the pressure sensor belongs. According to the target pressure interval, the target user information using the oral care device is determined. If the capacitance signal and the pressure signal collected by the capacitance sensor meet the trigger condition corresponding to the touch module, the operation corresponding to the touch module and the target user information is performed.

[0165] It should be noted that the oral care device is pre-set with multiple pressure intervals, and the target pressure interval is the pressure interval to which the pressure signal collected by the pressure sensor belongs. Different users have different oral care preferences, and different users press the touch module with different pressures. That is, even if the pressure of pressing the touch module is greater than the first pressure threshold, the pressure signal detected by the pressure sensor belongs to a different pressure interval. The pressure interval is associated with the user information of the user, so that when the user triggers the touch module, the corresponding operation of the user is executed, thereby improving the degree of intelligence.

[0166] In some embodiments, the oral care device responds to the setting operation of the touch module, displays multiple executable operations corresponding to the touch module, and responds to the user's selection operation of the target executable operation, and stores the pressure signal corresponding to the setting operation and the target executable operation in correspondence. Wherein, the setting operation includes a pressing operation on the touch module, and the setting operation is different from the triggering operation of the touch module. If the triggering operation includes a single-click operation, the setting operation may include a double-click operation or a long-press operation. The executable operation may include but is not limited to checking the power of the oral care device, starting the oral care device to perform a care operation (when the oral care device includes an electric toothbrush, the care operation includes brushing teeth), turning off the execution of the care operation, or checking the care results. In this embodiment, by obtaining the pressure signal of the user pressing the touch module, and storing the pressure interval to which the pressure signal belongs in correspondence with the executable operation selected by the user, the oral care device can execute the executable operation corresponding to the user when different users press the touch module, thereby improving the flexibility of the oral care device and the user experience.

[0167] In this embodiment, the oral care device determines the target pressure interval to which the pressure signal collected by the pressure sensor belongs. If the capacitance signal and pressure signal collected by the capacitance sensor meet the triggering conditions corresponding to the touch module, the operation corresponding to the touch module and the target pressure interval is performed, so that the oral care device can perform the operation matched with the user, thereby improving the intelligence of the oral care device.

[0168] Please refer to Figure 7 , which shows a flow chart of another touch control method provided by an embodiment of the present application, and the touch control method can be applied to an oral care device. The oral care device includes a touch control module, and the touch control module includes a capacitive sensor and a pressure sensor.

[0169] like Figure 7 As shown, the method may include steps 702 to 734.

[0170] Step 702, obtaining a capacitance signal.

[0171] Specifically, the MCU may obtain a capacitance signal collected by the capacitance sensor.

[0172] Step 704 , determining whether the capacitance signal is 0 or abnormally high for n seconds. If so, executing steps 706 to 708 ; if not, executing step 710 .

[0173] Specifically, it is determined whether the multiple capacitance signals are all greater than the second target capacitance, or the multiple capacitance signals continuously collected by the capacitance sensor are all equal to zero. If so, step 706 to step 708 are performed, and if not, step 710 is performed. Exemplarily, the range of n may include 3 seconds to 8 seconds. Optionally, n may be 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds or 8 seconds, etc.

[0174] Step 706: The triggering condition of the touch module is that the pressure signal is greater than the first pressure threshold.

[0175] It should be noted that when the capacitive sensor in the touch module fails, for example, the capacitive signal is 0 for n seconds, or is abnormally high for n seconds (greater than the second target capacitance for n seconds, far exceeding the normal capacitive signal of a human body touching the touch module), the trigger condition of the touch module is changed to single pressure trigger, that is, when the pressure signal reaches the normal pressure threshold (first pressure threshold), the touch module can be triggered. Exemplarily, the first pressure threshold is 1.96N.

[0176] Step 708, prompting the user that the touch module is abnormal.

[0177] It should be noted that when the touch module is triggered by a normal pressure threshold, a second prompt message may be output to prompt the user that the touch module is invalid.

[0178] Step 710, determining whether the oral care device is in operation, if so, executing steps 712 to 714, if not, executing steps 724 to 726.

[0179] Step 712 : The triggering conditions of the touch module include the normal mode, only the high pressure threshold, and the low capacitance threshold and the normal pressure threshold.

[0180] It should be noted that the normal mode is that the capacitance signal is greater than the first capacitance threshold, and the pressure signal is greater than the first pressure threshold. Only the high pressure threshold is that the pressure signal is greater than the second pressure threshold, and the second pressure threshold is greater than the first pressure threshold. The low capacitance threshold and normal pressure threshold are that the capacitance signal is greater than the second capacitance threshold and the pressure signal is greater than the third pressure threshold, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is equal to the first pressure threshold.

[0181] Step 714, determine whether the normal mode is met, if so, execute step 716, if not, execute step 718.

[0182] Specifically, it is determined whether the capacitance signal and the pressure signal meet the normal mode. If so, step 716 is executed; if not, step 718 is executed.

[0183] Step 716, executing the operation corresponding to the touch module.

[0184] Step 718, determine whether only the high pressure threshold is met, or the low capacitance threshold and the normal pressure threshold are met, if not, execute step 720, if yes, execute step 722.

[0185] Step 720: Do not perform the operation corresponding to the touch module.

[0186] Step 722, executing the operation corresponding to the touch module, and notifying the user to clean the touch module.

[0187] Step 724 : The triggering condition of the touch module includes a normal mode, a low capacitance threshold and a high pressure threshold.

[0188] It should be noted that the low capacitance threshold and the high pressure threshold mean that the capacitance signal is greater than the second capacitance threshold, and the pressure signal is greater than the third pressure threshold, the second capacitance threshold is less than the first capacitance threshold, and the third pressure threshold is greater than the first pressure threshold.

[0189] Step 726, determine whether the normal mode is met, if so, execute step 728, if not, execute step 730.

[0190] Specifically, it is determined whether the capacitance signal and the pressure signal meet the normal mode. If so, step 728 is executed; if not, step 730 is executed.

[0191] Step 728, executing the operation corresponding to the touch module.

[0192] Step 730 , determine whether the low capacitance threshold and the high pressure threshold are met, if not, execute step 732 , if not, execute step 734 .

[0193] Step 732: Do not execute the operation corresponding to the touch module.

[0194] Step 734 , executing the operation corresponding to the touch module and notifying the user to clean the touch module.

[0195] In this embodiment, if the touch module is triggered through an abnormal mode, it means that the capacitance signal detected by the capacitance sensor in the touch module has not reached the first capacitance threshold. There is a high probability that there is dirt or foreign matter on the touch module. The oral care device can remind the user to clean the touch module through the display screen or terminal device to improve the user experience.

[0196] In the related art, when the capacitive sensor in the touch module fails or the touch module is covered with stains (the sensitivity of the capacitive sensor decreases), causing the capacitive signal collected by the capacitive sensor to fail to reach the first capacitive threshold, the touch module will completely fail, affecting the user experience.

[0197] In this embodiment, by detecting the capacitance signal collected by the capacitance sensor and combining it with the working status of the oral care device, a suitable trigger condition is selected to avoid the complete failure of the touch module. At the same time, the touch module can still maintain a certain anti-mistouch function, which can reduce the failure rate of the touch module without increasing the hardware cost of the oral care device, improve the operation accuracy, and improve the user experience.

[0198] Please refer to Figure 8 , which shows a schematic diagram of the structure of a touch device disclosed in an embodiment of the present application. The device can be applied to oral care equipment. The oral care equipment includes a touch module, and the touch module includes a capacitive sensor and a pressure sensor.

[0199] like Figure 8As shown, the touch device 800 may include a capacitance acquisition module 810, a switching module 820, a pressure acquisition module 830 and an execution module 840. Among them, the capacitance acquisition module 810 is used to acquire the capacitance signal collected by the capacitance sensor.

[0208] In some embodiments, the touch control device 800 further includes a first output module. The first output module is used to output first prompt information when the capacitance signal collected by the capacitance sensor is less than the first target capacitance; the first prompt information is used to indicate that the sensitivity of the capacitance sensor decreases and / or to indicate a solution strategy for the decrease in the sensitivity of the capacitance sensor.

[0209] In some embodiments, the first output module is further used to output the first prompt information when the capacitance signal collected by the capacitance sensor is smaller than the first target capacitance and the capacitance signal and the pressure signal collected by the capacitance sensor meet the second trigger condition.

[0210] In some embodiments, the first prompt information includes cleaning prompt information, and the first output module is further used to output cleaning prompt information when the capacitance signal collected by the capacitance sensor is less than the first target capacitance, and the cleaning prompt information is used to prompt the touch module to be cleaned.

[0211] In some embodiments, the touch control device 800 further includes a condition switching module. The condition switching module is used to switch the trigger condition corresponding to the touch control module from the first trigger condition to the third trigger condition if the capacitance signal is greater than the second target capacitance, or equal to zero, and the third trigger condition is that the pressure signal collected by the pressure sensor is greater than the first pressure threshold, and the second target capacitance is greater than the first target capacitance.

[0212] In some embodiments, the touch control device 800 further includes a second output module. The second output module is used to output second prompt information when the capacitance signal is greater than the second target capacitance or equal to zero; the second prompt information is used to indicate that the capacitance sensor fails and / or to indicate a solution strategy for the capacitance sensor failure.

[0213] In some embodiments, the oral care device further includes other touch modules. The touch device 800 further includes a third output module and a selection execution module. The third output module is used to output selection prompt information in response to satisfying the fourth trigger condition corresponding to other touch modules when the capacitance signal collected by the capacitance sensor in the touch module is less than the first target capacitance, and the selection prompt information is used to instruct the user to select and execute the operation corresponding to the touch module, or to execute the operation corresponding to other touch modules. The selection execution module is used to execute the operation corresponding to the target touch module corresponding to the target selection operation in response to the target selection operation.

[0214] In some embodiments, the touch control device 800 further includes a first determination module and an improvement module. The first determination module is used to determine a change value corresponding to a capacitance signal collected by the capacitance sensor. The improvement module is used to increase a first capacitance threshold corresponding to a first trigger condition if the capacitance signal collected by the capacitance sensor is greater than or equal to a first target capacitance and the change value is greater than a change threshold and the pressure signal collected by the pressure sensor is less than a preset pressure.

[0215] In some embodiments, the touch control device 800 further includes a second determination module. The second determination module is used to determine the target pressure interval to which the pressure signal collected by the pressure sensor belongs. The execution module is also used to execute operations corresponding to the touch control module and the target pressure interval.

[0216] In an embodiment of the present application, the touch device includes a capacitance acquisition module, a switching module, a pressure acquisition module and an execution module. The capacitance acquisition module acquires the capacitance signal collected by the capacitance sensor, and the switching module switches the trigger condition corresponding to the touch module from the first trigger condition to the second trigger condition if the capacitance signal collected by the capacitance sensor is less than the first target capacitance; the second capacitance threshold corresponding to the second trigger condition is less than the first capacitance threshold corresponding to the first trigger condition, and / or the second pressure threshold corresponding to the second trigger condition is greater than the first pressure threshold corresponding to the first trigger condition. The pressure signal collected by the pressure sensor is acquired by the pressure acquisition module, and the execution module executes the operation corresponding to the touch module when the capacitance signal and pressure signal collected by the capacitance sensor meet the second trigger condition. The oral care device can switch the trigger condition corresponding to the touch module to a second trigger condition with a lower capacitance threshold and / or a higher pressure threshold when the capacitance signal collected by the capacitance sensor is small, that is, when the sensitivity of the capacitance sensor decreases. This allows the capacitance sensor to detect a smaller capacitance signal and / or only consider the pressure signal collected by the pressure sensor. Even if the sensitivity of the capacitance sensor decreases, the trigger operation performed by the user can meet the second trigger condition, thereby triggering the touch module, reducing the failure rate of the touch module, improving operation accuracy, and improving user experience.

[0217] At the same time, since the pressure threshold is increased, the phenomenon of the touch module being falsely triggered due to collision between other objects and the touch module can be reduced, thereby reducing the false trigger rate of the touch module.
