[0019] In one embodiment, the oral irrigator pre-stores a second matching relationship table between the number of charging cycles and the charging start threshold; before the step of controlling the battery to start charging if the battery power is less than or equal to the first charging start threshold, the method further includes:

[0020] Searching the third charging start threshold corresponding to the number of charging cycles in the second matching relationship table; wherein the third charging start threshold is greater than or equal to the first charging start threshold;

[0021] If the first charging start threshold of the battery is not equal to the third charging start threshold, the first charging start threshold is replaced by the third charging start threshold as a new first charging start threshold.

[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] The main solution of the embodiment of the present application is: obtaining the on / off status between the battery and the charging base and the battery power. If the battery is in a charging connection state and the battery power is less than or equal to the first charging start threshold, the battery is controlled to start charging until the battery power reaches the first charging stop threshold, and then the battery is controlled to stop charging. Among them, the first charging stop threshold is greater than the first charging start threshold. If the battery is in a charging disconnection state and the battery power is less than or equal to the first low-power prompt threshold, a low-power prompt message is output; wherein, the first low-power prompt threshold is less than or equal to the first charging start threshold.

[0047] In the embodiments of the present application, for ease of description, the following description will be made using a water flosser as an execution subject of a method for identifying a power management method for a water flosser, wherein the water flosser includes a battery and a charging stand.

[0048] It should be noted that the power management method of existing oral irrigators usually relies on the user to manually charge the battery of the oral irrigator. However, since the user may be negligent or forget to charge, the battery will be insufficient when used next time, thus interrupting the use of the oral irrigator and seriously affecting the user experience.

[0049] The present application provides a solution, so that when the battery is in a charging connection state and the battery power is less than or equal to a first charging start threshold, the battery can be controlled to start charging, and the battery can be controlled to stop charging when the battery power reaches a first charging stop threshold. In this way, the battery can be automatically recharged when the battery power is less than or equal to the first charging start threshold, so that the battery power can always be maintained at a healthy power consumption level, so that the battery power is not easily insufficient when used next time due to negligence or forgetting to charge. In addition, when the battery is in a charging disconnection state and the battery power is less than or equal to a first low-power prompt threshold, a low-power prompt message is output to prompt the user to charge the battery in time. In this way, the present application can solve the technical problem that the existing water flosser relies on manual charging, resulting in the battery being in an insufficient power state due to user negligence or forgetting to charge, affecting the user experience.

[0050] Based on this, the present application embodiment provides a power management method for a water flosser. Figure 1 In this embodiment, the power management method of the water flosser includes steps S10 to S30:

[0051] Step S10, obtaining the on / off status between the battery and the charging base and the battery power.

[0052] It should be noted that the on / off state between the battery and the charging station includes a charging connection state and a charging disconnection state. The battery can be charged in the charging connection state, and cannot be charged in the charging disconnection state.

[0053] It should be noted that the oral irrigator includes a battery and a charging stand. The battery can be arranged on the main body of the oral irrigator, and the charging stand can be provided with a groove or a platform for accommodating the oral irrigator. The charging stand can be provided with metal contacts or conductive sheets, which contact with corresponding contacts on the main body of the oral irrigator to form an electrical connection. Alternatively, the charging stand can include a wireless charging coil, and a corresponding receiving coil is also embedded in the main body of the oral irrigator to transmit energy through electromagnetic induction. Alternatively, the main body of the oral irrigator can be directly connected to the charging stand via a charging cable. For example, when a groove and a metal contact are provided on the charging stand, when the user has finished using the oral irrigator, the main body of the oral irrigator can be placed on the groove of the charging stand, and the battery and the charging stand are in a charging connection state. If the main body of the oral irrigator is not placed on the groove of the charging stand, the battery and the charging stand are in a charging disconnection state. An indicator light can be provided on the charging stand to indicate the charging status of the battery.

[0054] In one possible implementation, referring to Figure 5 The water flosser may include a control circuit and a battery management circuit. The control circuit may read through the battery management circuit whether the voltage input from the charging stand to the battery reaches a preset voltage to determine the charging on / off state between the battery and the charging stand. Specifically, if the preset voltage is reached, it is determined that the battery and the charging stand are in a charging connection state; if the preset voltage is not reached, it is determined that the battery and the charging stand are in a charging disconnection state. The charging stand may convert an external power source into a charging power input for the battery. At the same time, the battery management circuit may obtain the remaining power information of the battery and send it to the control circuit. The control circuit may be composed of a control chip such as an MCU chip, and the battery management circuit may be composed of a battery management chip, etc. The remaining power information of the battery may be expressed as a percentage of the rated power.

[0055] Step S20, if the battery is in a charging connection state and the battery power is less than or equal to a first charging start threshold, the battery is controlled to start charging until the battery power reaches a first charging stop threshold, and then the battery is controlled to stop charging; wherein the first charging stop threshold is greater than the first charging start threshold.

[0056] It should be noted that the first charging start threshold can be set to 90% of the power, and the first charging stop threshold can be set to 100% of the power. Then, when the battery power is not higher than 90%, the battery is controlled to start charging, and when the battery power reaches 100%, the battery is controlled to stop charging. In this way, the battery power can be guaranteed to be between 90% and 100%, and automatic recharging is performed when the power is less than or equal to 90%. In this way, the battery power can be guaranteed to be maintained at a healthy power consumption level, and the battery power is not prone to insufficient power.

[0057] It should be noted that the first charging start threshold can be specifically set according to the capacity of the battery. If the capacity of the battery is large, the first charging start threshold can be set lower. If the capacity of the battery is relatively small, the first charging start threshold can be set relatively high. Both can ensure that the battery power is always maintained at a healthy power consumption level. No limitation is made here.

[0058] Step S30: If the battery is in a charging disconnected state and the battery power is less than or equal to a first low-battery warning threshold, a low-battery warning message is output.

[0059] It should be noted that the low battery reminder information is used to remind the user to place the main body of the water flosser including the battery on the charging stand so that the battery is in a charging connection state. Among them, the first low battery reminder threshold can be less than the first charging start threshold and can be set to 20% of the power to remind the user to charge in time.

[0060] In this way, compared with the prior art, the present embodiment can realize automatic recharging of the oral irrigator, so that the battery power is always maintained at a healthy power usage level, and can prompt the user to charge when the battery power is less than or equal to the first low-battery prompt threshold, which can solve the technical problem that the existing oral irrigator relies on manual charging, resulting in the battery being in a low-power state due to user negligence or forgetting to charge.

[0061] In one possible implementation, referring to Figure 2 After executing the step of controlling the battery to start charging and before executing the step of controlling the battery to stop charging, the power management method of the water flosser may further include steps A1 to A2:

[0062] Step A1, detecting the charging voltage during the battery charging process.

[0063] Step A2: If the charging voltage of the battery is greater than or equal to the first charging cut-off voltage, the battery is controlled to stop charging and an overvoltage prompt message is output.

[0064] It should be noted that the charging voltage of the battery during the charging process can be detected by the battery management circuit. The water flosser can also include an indicator light circuit, and the control circuit can display an overvoltage prompt message by controlling the operation of the indicator light circuit. In this embodiment, the first charging cut-off voltage can be set to 6.5V. When the charging voltage of the battery is greater than or equal to 6.5V, the battery is controlled to stop charging to protect the charging safety of the battery.

[0065] It should be noted that the remaining power information of the battery can also be expressed in the form of voltage. For example, if the full-charge voltage output of the battery is 4.2V, the first charge start threshold can be set to 4.0V, the first charge stop threshold can be set to 4.2V, the first low power threshold can be set to 2.8V, and the first charge cut-off voltage can be set to 6.5V.

[0066] In one feasible implementation, step S30 includes step S31:

[0067] Step S31, if the battery is continuously in the charging disconnected state and the battery power is less than or equal to the first low-battery warning threshold, a low-battery warning message is output, and the device is controlled to shut down after a preset time.

[0068] It should be noted that the first low-battery reminder threshold can be set to 20%, and the preset duration can be set to 2 minutes. When the user is using the water flosser, the battery power gradually drops to 20%. At this time, the indicator light can flash and / or the buzzer can sound to remind the user that the battery is low. If the user does not charge it in time, after 2 minutes of use, the water flosser is controlled to automatically shut down. In this way, the present embodiment can remind the user in time when the battery power is low, and automatically shut down after a preset time to avoid the battery from entering an over-discharge state, thereby extending its service life. It is understandable that in the first five seconds of executing the shutdown, the indicator light can be controlled to flash to remind the user that a shutdown operation is about to be performed.

[0069] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 3 , step S20 includes steps S21-S22:

[0070] Step S21, if the battery is in a charging connection state, obtain the number of charging cycles.

[0071] Step S22: If the battery power is less than or equal to the first charging start threshold, the battery is controlled to start charging until the battery power reaches the first charging stop threshold, the number of charging cycles is recorded plus one, and the battery is controlled to stop charging.

[0072] It should be noted that the battery power information includes the rated power and the actual power. The rated power reflects the maximum capacity of the battery, which is the theoretical maximum value. The actual power reflects the actual state of the battery during use and will gradually decrease with the increase in the number of charging cycles. For example, the actual power of the battery is close to 1000mAh. After about 365 charging cycles, the actual power of the battery may drop to about 900mAh.

[0073] It should be noted that the greater the difference between the first charge stop threshold and the first charge start threshold, the greater the number of charging cycles, the greater the number of full charge cycles, and the faster the actual power decays. Therefore, when considering the impact of the number of charging cycles on the actual power, the difference between the first charge stop threshold and the first charge start threshold can be taken into account. If the capacity of the battery is large, the first charge start threshold can be set below the first power level, for example, it can be set below 50% of the power. At this time, the difference between the first charge start threshold (below 50% of the power) and the first charge stop threshold (close to 100% of the power) is large, and the number of charging cycles can more clearly reflect the state change of the actual power of the battery.

[0074] In this embodiment, by recording the number of charging cycles, it can help analyze the health of the battery, help to better maintain the performance of the battery, delay battery aging, and enhance the user experience.

[0075] Based on the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above-mentioned second embodiment can be referred to the above introduction, and will not be repeated in the following. Figure 5 The dental flosser has a pre-stored first matching relationship table of the number of charging cycles and the charging stop threshold. Figure 4 , step S22 includes steps B1 to B2:

[0076] Step B1, if the battery power is less than or equal to the first charging start threshold, control the battery to start charging, and search the first matching relationship table for a second charging stop threshold corresponding to the number of charging cycles; wherein the second charging stop threshold is less than or equal to the first charging stop threshold.

[0077] Step B2: if the first charging stop threshold of the battery is not equal to the second charging stop threshold, the first charging stop threshold is replaced by the second charging stop threshold as a new first charging stop threshold, until the battery power reaches the new first charging stop threshold, the number of charging cycles is recorded plus one, and the battery is controlled to stop charging.

[0078] It should be noted that in the first matching relationship table, the charging stop threshold corresponding to the larger number of charging cycles is less than or equal to the charging stop threshold corresponding to the smaller number of charging cycles. In this embodiment, when searching, the second charging stop threshold is the larger charging stop threshold corresponding to the current number of charging cycles, and the first charging stop threshold is the smaller charging stop threshold corresponding to the previous number of charging cycles. For example, in the first matching relationship table, when the number of charging cycles is less than or equal to 500, the charging stop threshold is 98% of the rated power; when the number of charging cycles is greater than 500 and less than or equal to 1000, the charging stop threshold is 95% of the rated power; when the number of charging cycles is greater than 1000, the charging stop threshold is 90% of the rated power, and the first charging stop threshold is 98% of the rated power for the first charging. Then, in the first to 499th charging cycles, the second charging stop thresholds corresponding to the first to 499th charging cycles are all 98% of the rated power, which is equal to the first charging stop threshold of 98% of the rated power, and no replacement is performed. At the 500th charging cycle, the second charging stop threshold corresponding to the 500th charging cycle is found in the first matching relationship table to be 95% of the rated power. At this time, the second charging stop threshold replaces the first charging stop threshold as the new first charging stop threshold, that is, the new first charging stop threshold is 95% of the rated power. Similarly, at the 1000th charging cycle, the second charging stop threshold replaces the first charging stop threshold as the new first charging stop threshold, that is, the new first charging stop threshold is 90% of the rated power. In this way, in this embodiment, the problem of battery overcharging caused by the gradual decrease in actual power as the number of charging cycles increases is solved, thereby avoiding the impact of overcharging on battery life, and effectively preventing the battery from aging too quickly due to overcharging.

[0079] Based on the second embodiment of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the above-mentioned second embodiment can refer to the above introduction, and will not be repeated in the following. Figure 5 The water flosser pre-stores a second matching relationship table between the number of charging cycles and the charging start threshold. Before the step of controlling the battery to start charging in step S22 if the battery power is less than or equal to the first charging start threshold, the power management method of the water flosser further includes steps C1 to C2:

[0080] Step C1, searching a third charging start threshold value corresponding to the number of charging cycles in a second matching relationship table; wherein the third charging start threshold value is greater than or equal to the first charging start threshold value.

[0081] Step C2: if the first charge start threshold of the battery is not equal to the third charge start threshold, the first charge start threshold is replaced by the third charge start threshold as a new first charge start threshold.

[0082] It should be noted that in the second matching relationship table, the charging start threshold corresponding to the larger number of charging cycles is greater than or equal to the charging start threshold corresponding to the smaller number of charging cycles. For example, in the second matching relationship table, when the number of charging cycles is less than or equal to 500, the charging start threshold is set to 12% of the rated power; when the number of charging cycles is greater than 500 and less than or equal to 1000, the charging start threshold is 15% of the rated power; when the number of charging cycles is greater than 1000, the charging start threshold is 20% of the rated power, and the first charging start threshold is 12% of the rated power for the first charging. Then, in the first to 499th charging cycles, the third charging start threshold corresponding to the first to 499th charging cycles is found in the second matching relationship table to be 12% of the rated power, which is equal to the first charging start threshold of 12% of the rated power, and no replacement is performed. At the 500th charging cycle, the third charging start threshold corresponding to the 500th charging cycle is found in the second matching relationship table to be 15% of the rated power. At this time, the third charging start threshold replaces the first charging start threshold as the new first charging start threshold, that is, the new first charging start threshold is 15% of the rated power. Similarly, at the 1000th charging cycle, the third charging start threshold replaces the first charging start threshold as the new first charging start threshold, that is, the new first charging start threshold is 20% of the rated power. In this way, in this embodiment, as the number of charging cycles increases, the actual power gradually decreases, but because the charging start threshold is increased, the battery can also be at a healthy power consumption level. At the healthy power consumption level, the user can at least use the water flosser The number of times will not decrease, which enhances the user's experience. In addition, increasing the charging start threshold can also effectively alleviate the battery from aging too quickly due to over-discharge.

[0083] Based on the second embodiment of the present application, in the fifth embodiment of the present application, the same or similar contents as those in the above-mentioned second embodiment can be referred to the above introduction, and no further description will be given later. Figure 5 The water flosser pre-stores a third matching relationship table of the number of charging cycles and the charging cut-off voltage. Before the step of controlling the battery to stop charging and outputting an overvoltage prompt message in step S22 if the charging voltage of the battery is greater than or equal to the first charging cut-off voltage, the power management method of the water flosser further includes steps D1 to D2:

[0084] Step D1, searching a third matching relationship table for a second charge cut-off voltage corresponding to the number of charge cycles; wherein the second charge cut-off voltage is less than or equal to the first charge cut-off voltage.

[0085] Step D2: if the first charge cut-off voltage of the battery is not equal to the second charge cut-off voltage, the first charge cut-off voltage is replaced by the second charge cut-off voltage as a new first charge cut-off voltage.

[0086] It should be noted that in the third matching relationship table, the charging cut-off voltage corresponding to the larger number of charging cycles is less than or equal to the charging cut-off voltage corresponding to the smaller number of charging cycles. For example, in the third matching relationship table, when the number of charging cycles is less than or equal to 500, the charging cut-off voltage is set to 3.6V; when the number of charging cycles is greater than 500 and less than or equal to 1000, the charging cut-off voltage is 3.4V; when the number of charging cycles is greater than 1000, the charging cut-off voltage is 3.0V, and the first charging cut-off voltage is 3.6V during the first charging. Then, in the first to 499th charging cycles, the second charging cut-off voltage corresponding to the first to 499th charging cycles is found in the third matching relationship table to be 3.6V, which is equal to the first charging cut-off voltage of 3.6V, and no replacement is performed. At the 500th charging cycle, the second charging cut-off voltage corresponding to the 500th charging cycle is found in the second matching relationship table to be 3.4V. At this time, the first charging cut-off voltage is replaced by the second charging cut-off voltage as a new first charging cut-off voltage, that is, the new first charging cut-off voltage is 3.4V. Similarly, at the 1000th charging cycle, the first charging cut-off voltage is replaced by the second charging cut-off voltage as a new first charging cut-off voltage, that is, the new first charging cut-off voltage is 3.0V. In this way, in this embodiment, as the number of charging cycles increases, the battery health state decreases and the voltage resistance decreases, but because the charging cut-off voltage is reduced, the battery is still charged within the voltage resistance range, which improves safety.

[0087] Based on the second embodiment of the present application, in the sixth embodiment of the present application, the same or similar contents as those in the above-mentioned second embodiment can be referred to the above introduction, and will not be repeated in the following. Figure 5 The water flosser pre-stores a fourth matching relationship table of the number of charging cycles and the low-battery warning threshold, and step S30 includes steps S31 to S33:

[0088] Step S31, if the battery is in a charging disconnected state, searching a fourth matching relationship table for a second low-battery warning threshold value corresponding to the number of charging cycles; wherein the second low-battery warning threshold value is greater than or equal to the first low-battery warning threshold value.

[0089] Step S32: if the first low-battery warning threshold of the battery is not equal to the second low-battery warning threshold, the first low-battery warning threshold is replaced by the second low-battery warning threshold as a new first low-battery warning threshold.

[0090] Step S33: if the battery power is less than or equal to the new first low-battery warning threshold, output low-battery warning information.

[0091] It should be noted that in the fourth matching relationship table, the low battery prompt threshold corresponding to the larger number of charging cycles is greater than or equal to the low battery prompt threshold corresponding to the smaller number of charging cycles. For example, in the fourth matching relationship table, when the number of charging cycles is less than or equal to 500, the low battery prompt threshold is set to 10% of the rated power; when the number of charging cycles is greater than 500 and less than or equal to 1000, the low battery prompt threshold is 12% of the rated power; when the number of charging cycles is greater than 1000, the low battery prompt threshold is 15% of the rated power, and the first low battery prompt threshold is 10% of the rated power during the first charging. Then, in the first to 499th charging cycles, the second low battery prompt threshold corresponding to the first to 499th charging cycles is found in the fourth matching relationship table to be 10% of the rated power, which is equal to the first low battery prompt threshold of 10% of the rated power, and no replacement is performed. At the 500th charging cycle, the second low battery prompt threshold value corresponding to the 500th charging cycle number is searched in the second matching relationship table as 12% of the rated power. At this time, the second low battery prompt threshold value replaces the first low battery prompt threshold value as the new first low battery prompt threshold value, that is, the new first low battery prompt threshold value is 12% of the rated power. Similarly, at the 1000th charging cycle, the second low battery prompt threshold value replaces the first low battery prompt threshold value as the new first low battery prompt threshold value, that is, the new first low battery prompt threshold value is 15% of the rated power. In this way, in this embodiment, as the number of charging cycles increases, the actual power also gradually decreases, but because the low power prompt threshold value is increased, the user can be notified in time to charge the water flosser. In addition, it also alleviates the problem of battery over-discharge caused by bad user habits, such as using the water flosser in a low power state, thereby effectively preventing the battery from aging too quickly due to over-discharge.
