[0002] Some oral care devices combine the functions of an electric toothbrush and an electric water flosser. The motor rotates and vibrates at high speed, causing the brush head to vibrate at a high frequency, or the punch head to output high-pressure water jets to deeply clean the teeth and between teeth. This can more effectively remove dental plaque and reduce oral diseases such as gingivitis, periodontal disease, and bleeding gums.

[0003] At present, some oral care devices include a main unit and a handle, and the main unit and the handle are respectively provided with internal power components and a power source. The power state of the power source is an important factor affecting the performance of the oral care device. Wireless charging from the main unit to the handle can effectively improve the convenience of use. However, the existing wireless charging method does not balance the power between different devices of the oral care device. When the power of the handle is saturated or the power of the main unit is insufficient, which is not suitable for charging, wireless charging continues, resulting in power consumption, increased use costs, safety hazards, and reduced product life.

[0032] In this specification, an oral care device is provided. This specification also relates to a charging method for the oral care device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0033] See also Figure 1 , Figure 1 FIG. 1 shows a schematic diagram of the structure of an oral care device provided by an embodiment of the present specification, such as Figure 1 As shown:

[0034] The oral care device 10 of the embodiment of the present specification includes a host 110, a handle 120 and a wireless charging module 130, the host 110 includes a fluid reservoir and a pump fluidically connected to the fluid reservoir, and the handle 120 is fluidically connected to the host 110;

[0035] The host 110 is used to respond to the charging trigger signal, obtain the handle power of the handle 120, compare the handle power with the host power of the host 110, and determine whether the power balance condition is reached. If not, turn on the wireless charging module 130 to transfer the power of the host 110 to the handle 120.

[0036] The host 110 is the core control component of the oral care device 10, and is equipped with a host power supply and a fluid system. The host power supply includes but is not limited to: a host battery and / or a host external power supply circuit, and the fluid system includes a fluid reservoir and a pump connected to the fluid reservoir. The host 110 realizes the oral care function by running the pump to transport the fluid stored in the fluid reservoir to the oral care head (brush head or stamping head) of the handle 120. The host 110 controls the wireless charging module 130 to turn on and transmit the power of the host 110 to the handle 120, or turns off the wireless charging module 130 to stop transmitting the power of the host 110 to the handle 120.

[0037] The handle 120 is a user oral interaction component of the oral care device 10, and is equipped with a handle battery, a handle motor and a fluid connection tube. An oral care head is configured at one end of the handle 120, and the other end is fluidically connected to the host 110 through the fluid connection tube. Optionally, the oral care head can be replaced according to the oral care function. For example, when the tooth brushing function is realized, the brush head can be replaced. For another example, when the tooth flushing function is realized, the tooth flushing head can be replaced. For another example, a flushing integrated care head with an integrated brush head and a tooth flushing head can be replaced.

[0038] The handle 120 can be adjustably connected to the host 110 via a magnetic attachment structure, which is a magnet or a structure that can be attracted by magnetic attraction. Optionally, the handle 120 can also be detachably connected to the host 110 by hanging or buckling.

[0039] The wireless charging module 130 is a functional module that uses electromagnetic induction, electromagnetic resonance or other wireless transmission methods to perform contactless charging for the handle battery. Among them, the wireless charging module includes but is not limited to: a wireless charging module of the Qi standard and a wireless charging module of the AirFuelAlliance standard. The wireless charging module 130 is turned on by the control of the host 110. The wireless charging module 130 can be built into the host 110 or external to the host 110, which is not limited here.

[0040] The charging trigger signal is an electronic signal used to control the start of the wireless charging module 130 .

[0041] The handle power is the current remaining power of the handle battery of the handle 120. The level of the handle power directly affects the remaining use time of the handle 120. Optionally, the handle power is displayed to the user through an LED light or a display screen on the handle 120 so that the user can intuitively understand the remaining use time.

[0042] The host power of the host 110 is the current remaining power of the host battery of the host 110. The level of the host power directly affects the remaining use time of the host 110. The host power needs to be continuously monitored to ensure that sufficient power can be provided in time when the handle 120 needs to be charged. Optionally, the host power is displayed to the user on the host 110 through an LED light or a display screen so that the user can intuitively understand the remaining use time.

[0043] In an optional embodiment of the present specification, the host 110 is used to respond to a charging trigger signal, obtain the handle power of the handle 120, compare the handle power with the host power of the host 110, determine whether the power balance condition is reached, and if so, turn off the wireless charging module 130.

[0044] In the embodiment of this specification, the control logic of the host control unit 1110 is an AND gate logic, the inputs are respectively the charging trigger signal and the charging instruction, and the output is the control signal. The truth table is shown in Table 1:

[0045] Charging trigger signal Charging instructions Output control signal have have Turn on the wireless charging module 130 have none Turn off the wireless charging module 130 none have Turn off the wireless charging module 130 none none Turn off the wireless charging module 130

[0046] Table 1

[0047] In addition, in order to protect the battery life of the host and optimize energy usage, the host power management also needs to consider the power balancing strategy, that is, to maintain a reasonable distribution between the power of the handle 120 and the host 110 to avoid energy waste caused by excessive discharge or frequent charging.

[0048] Compare the power of the handle with the host power of the host 110 to determine whether the power balance condition is met. An optional method is to compare the ratio of the power of the handle and the host power of the host 110 to determine whether the power balance condition is met. For example, assume that the power of the handle is 1500mAh and the power of the host is 3000mAh. According to the calculation method of the power ratio (host power / handle power), the ratio is 2:1, and the preset ideal power ratio condition (1:2 or 2:1) is obtained. When the host power / handle power is greater than 2:1, it is determined that the power balance condition is not met at this time, and wireless charging can be started to replenish power to the handle to ensure that the power of the host remains sufficient while the power of the handle is increased. Another optional method is to compare the power of the handle with the value of the host power of the host 110 to determine whether the power balance condition is met, which is not limited here. For example, assume that the power of the handle is 2000mAh and the power of the host is 3500mAh. According to the power value difference method, the host power is set to be at least 1000mAh higher than the power of the handle. In this example, the power of the host is indeed 1500mAh more than that of the handle, far exceeding the set value of 1000mAh, so it is determined that the power balance condition has not been met and wireless charging can be performed. On the contrary, if the power of the handle is 2500mAh and the power of the host is 3000mAh, although the host power is still more, it is only 500mAh more and does not meet the power difference standard of 1000mAh. At this time, wireless charging will not be enabled. Another optional method is to compare the power percentages of the handle power and the host power of the host 110 to determine whether the power balance condition has been met, which is not limited here. For example, assume that the power percentage of the handle is 10% and the power percentage of the host is 60%. The host power percentage is greater than the power percentage of the handle, so it is determined that the power balance condition has not been met, and wireless charging can be performed to replenish power to the handle. As the host charges the handle, the host battery percentage gradually decreases and the handle battery percentage gradually increases. For example, assuming the handle battery percentage rises to 30% and the host battery percentage drops to 30%, it means that charging equalization has been completed, and the host will end the wireless charging transmission. The battery percentages of the handle and the host are the same, so that the power components in the host and the handle can work synchronously for a longer time.

[0049] In the embodiment of this specification, in response to the charging trigger signal, the power of the handle is compared with the power of the host, and the wireless charging module 130 is automatically turned on to transfer the power of the host 110 to the handle when the power balance condition is not reached, so as to avoid the occurrence of wireless charging in an unsuitable charging situation, balance the power storage of the host and the handle, so that the power elements in the host and the handle can work synchronously for a longer time. It effectively saves power, reduces the use cost and safety hazards, and improves the product life.

[0050] In an optional embodiment of the present specification, the host 110 is further used to obtain the host power of the host 110, and when the host power is less than a host power threshold, turn off the wireless charging module 130.

[0051] The host power threshold is a pre-set charging threshold for the host power. When the host power is less than or equal to the host power threshold, the host 110 will automatically trigger the generation of a charging disconnection instruction to prevent the host 110 from being unusable due to power exhaustion. For example, the host power threshold is set to 50%, and for another example, the host power threshold is set to 1000 mAh.

[0052] In the embodiments of this specification, wireless charging is automatically stopped by judging the remaining power of the host, thereby avoiding the continuation of wireless charging when it is not suitable for charging, effectively saving power, reducing the cost of use and safety hazards, and improving product life.

[0053] See also Figure 2 , Figure 2 FIG. 1 shows a structural diagram of another oral care device provided by an embodiment of the present specification, such as Figure 2 As shown:

[0054] In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110 and a host data transceiver unit 1120, and the handle 120 further includes a handle control unit 1210 and a handle data transceiver unit 1220;

[0055] The handle 120 is used to generate a charging instruction through the handle control unit 1210 when the handle power is less than or equal to the handle power threshold, and send the charging instruction to the host data transceiver unit through the handle data transceiver unit 1220;

[0056] The host 110 is also used to respond to the charging trigger signal, receive the charging instruction through the host data transceiver unit 1120, compare the handle power and the host power of the host 110, and determine whether the power balance condition is reached. If not, the wireless charging module 130 is turned on through the host control unit 1110 to transmit the power of the host 110 to the handle 120.

[0057] The host control unit 1110 is the core control module of the oral care device 10, which is responsible for monitoring and controlling the functions and operating status of the oral care device 10, including but not limited to: controlling the opening and closing of the wireless charging module 130, controlling the data transmission between the handle 120, and coordinating the collaborative work of various components. The host control unit 1110 is usually integrated with a microprocessor unit or a microcontroller unit, which can execute pre-programmed computer programs / instructions. For example, when the host data transceiver unit 1120 receives a charging instruction sent by the handle data transceiver unit 1220, the host control unit 1110 will determine the validity of the charging instruction and decide whether to turn on the wireless charging module 130 to transfer the power of the host 110 to the handle 120. For another example, when the host data transceiver unit 1120 receives a fluid output instruction sent by the handle data transceiver unit 1220, it ensures that the fluid is delivered to the oral care head of the handle 120 at an appropriate pressure and flow rate.

[0058] The host data transceiver unit 1120 is an electronic unit in the host 110 used to control data transmission between the handle 120, and is responsible for receiving data or command signals sent by the handle data transceiver unit 1220, including but not limited to: Bluetooth data transceiver unit, WiFi data transceiver unit, 2.4G data transceiver unit, near-field data transceiver unit and cable data transceiver unit.

[0059] The host control unit 1110 and the host data transceiver unit 1120 are electrically connected, and the host data transceiver unit 1120 sends a charging instruction to the host control unit 1110 through the electrical connection.

[0060] The handle control unit 1210 is a control unit in the handle 120 for monitoring and controlling the operating state of the handle 120. For example, for power monitoring, when the handle power is less than or equal to the handle power threshold, a charging instruction is generated by the handle control unit 1210, and the charging instruction is sent to the host data transceiver unit 1120 through the handle data transceiver unit 1220. For another example, for the control of the oral care mode, when different oral care modes are selected through the buttons on the handle 120, the handle control unit 1210 identifies and processes the switching signal of the oral care mode, adjusts the operating mode of the handle motor, and sends relevant command signals through the handle data transceiver unit 1220 to notify the host 110 to adjust the corresponding fluid output.

[0061] The handle data transceiver unit 1220 is an electronic unit in the handle 120 used for data transmission with the host 110, responsible for sending data or command signals to the host data transceiver unit 1120, including but not limited to: Bluetooth data transceiver unit, WiFi data transceiver unit, 2.4G data transceiver unit, near-field data transceiver unit and cable data transceiver unit.

[0062] There is an electrical connection between the handle control unit 1210 and the handle data transceiver unit 1220 , and the handle control unit 1210 sends a charging instruction to the handle data transceiver unit 1220 through the electrical connection.

[0063] The handle power threshold is a charging threshold preset for the handle power. When the handle power is less than or equal to the handle power threshold, the handle 120 will automatically trigger a charging instruction to prevent the handle 120 from being unusable due to power exhaustion. For example, the handle power threshold is set to 30%, and for another example, the handle power threshold is set to 1000 mAh.

[0064] The charging instruction is used to trigger the host control unit 1110 to control the command information for turning on the wireless charging module 130, and the charging instruction carries the information of the handle power. For example, when the handle 120 detects that the handle power is reduced to the handle power threshold (30% power) or lower than the handle power threshold (30% power), the handle control unit 1210 automatically generates a charging instruction, which is sent to the 2.4G host data transceiver unit 1120 of the host 110 through the 2.4G handle data transceiver unit 1220. The host 110 responds to the charging trigger signal, receives the charging instruction through the handle data transceiver unit 1220, and turns on the wireless charging module 130 through the host control unit 1110 to charge the handle 120, without manual intervention by the user.

[0065] The wireless charging module 130 is turned on through the host control unit 1110 to transmit the power of the host 110 to the handle. One optional method is: the MOS switch is controlled by the host control unit 1110, and the wireless charging module 130 is turned on to transmit the power of the host 110 to the handle 120. Another optional method is: the relay is controlled by the host control unit 1110, and the wireless charging module 130 is turned on to transmit the power of the host 110 to the handle 120. Another optional method is: the pulse width modulation controller is controlled by the host control unit 1110, and the wireless charging module 130 is turned on to transmit the power of the host 110 to the handle 120. There is no limitation here.

[0066] In the embodiments of the present specification, the wireless charging module 130 is turned on for on-demand charging only when the handle power level is less than or equal to the handle power threshold through charging instruction control, thereby avoiding charging when the handle power level is high, reducing unnecessary power loss of the host 110, and more effectively saving power, further reducing the cost of use and safety hazards, and further improving the product life of the oral care device 10.

[0067] See also Figure 2In an optional embodiment of the present specification, the handle 120 is also used to generate a charging instruction through the handle control unit 1210 when the handle power is less than or equal to the handle power threshold and the handle 120 is not in a charging state, and send the charging instruction to the host data transceiver unit 1120 through the handle data transceiver unit 1220.

[0068] See also Figure 2 In an optional embodiment of the present specification, the handle 120 is further used to generate a charging disconnection instruction through the handle control unit 1210 when the handle power is less than or equal to the handle power threshold and the handle 120 is in a charging state, and send the charging disconnection instruction to the host data transceiver unit 1120 through the handle data transceiver unit 1220;

[0069] The host 110 is also used to respond to the charging trigger signal, receive the charging disconnection instruction through the handle data transceiver unit 1220, and turn off the wireless charging module 130 through the host control unit 1110.

[0070] It should be noted that in addition to wireless charging, the handle 120 can also be charged by wired charging. Therefore, it is necessary to determine in advance whether the handle 120 is in a charging state. If it is in a charging state, the wireless charging module 130 is turned off. When it is not charging, the charging instruction can be sent to the host data transceiver unit 1120 through the handle data transceiver unit 1220, and further determine whether to turn on the wireless charging module 130 on the host 110 side.

[0071] The charging disconnection instruction is instruction information for stopping triggering the host control unit 1110 to control the opening of the wireless charging module 130, and the charging disconnection instruction carries information about the power level of the handle. For example, when the handle 120 detects that the power level of the handle is reduced to the handle power threshold (30% power) or is lower than the handle power threshold (30% power), the handle 120 is in a charging state, and the handle control unit 1210 automatically generates a charging disconnection instruction, which is sent to the 2.4G host data transceiver unit 1120 of the host 110 through the 2.4G handle data transceiver unit 1220. The host 110 responds to the charging trigger signal, receives the charging disconnection instruction through the handle data transceiver unit 1220, and turns off the wireless charging module 130 through the host control unit 1110.

[0072] In the embodiment of this specification, the control logic of the handle control unit 1210 is an AND gate logic, the inputs are whether the handle power is less than or equal to the handle power threshold, whether the handle 120 is in a charging state, and the output is a charging instruction or a charging disconnection instruction. The truth table is shown in Table 2:

[0073]

[0074] Table 2

[0075] In addition, in order to protect the battery life of the host and optimize energy usage, on the basis of determining whether the handle 120 is in a charging state, a power balancing strategy must also be considered, that is, to maintain a reasonable distribution of power between the handle 120 and the host 110 to avoid energy waste caused by excessive discharge or frequent charging.

[0076] The wireless charging module 130 is turned off through the host control unit 1110. One optional way is to control the MOS switch through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the relay through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the pulse width modulation controller through the host control unit 1110 to turn off the wireless charging module 130. There is no limitation here.

[0077] In the embodiments of this specification, the power level and charging status of the handle are intelligently detected, wireless charging is dynamically regulated, power balance management is achieved, and energy distribution is optimized, which not only extends the overall usage time and battery life of the oral care device 10, but also avoids unnecessary energy loss, optimizes energy management, and improves user experience.

[0078] See also Figure 2 In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110 and a host data transceiver unit 1120, and the handle 120 further includes a handle control unit 1210 and a handle data transceiver unit 1220;

[0079] The handle 120 is used to generate a charging disconnection instruction through the handle control unit 1210 when the power of the handle 120 is greater than the handle power threshold, and send the charging disconnection instruction to the host data transceiver unit 1120 through the handle data transceiver unit 1220;

[0080] The host 110 is further configured to respond to a charging trigger signal, receive a charging disconnection instruction through the host data transceiver unit 1120 , and shut down the wireless charging module 130 through the host control unit 1110 .

[0081] The charging disconnection instruction is the instruction information for stopping triggering the host control unit 1110 to control the opening of the wireless charging module 130, and the charging disconnection instruction carries the handle power. For example, when the handle 120 detects that the handle power is greater than the handle power threshold (30% power), the handle control unit 1210 automatically generates a charging disconnection instruction, which is sent to the 2.4G host data transceiver unit 1120 of the host 110 through the 2.4G handle data transceiver unit 1220. The host 110 responds to the charging trigger signal, receives the charging disconnection instruction through the handle data transceiver unit 1220, and turns off the wireless charging module 130 through the host control unit 1110, without manual intervention by the user.

[0082] The wireless charging module 130 is turned off through the host control unit 1110. One optional way is to control the MOS switch through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the relay through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the pulse width modulation controller through the host control unit 1110 to turn off the wireless charging module 130. There is no limitation here.

[0083] In the embodiment of the present specification, when the handle power level is greater than the handle power threshold, the wireless charging module 130 is shut down through the charging disconnection command control, thereby avoiding charging when the handle power level is high, reducing unnecessary power loss of the host 110, and more effectively saving power, further reducing the cost of use and safety hazards, and further improving the product life of the oral care device 10.

[0084] See also Figure 2 In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110;

[0085] The host 110 is further used to obtain the host temperature of the host 110 , and when the host temperature is not within the host temperature threshold range, the wireless charging module 130 is turned off through the host control unit 1110 .

[0086] The host temperature is the temperature measurement value of the electronic components inside the host 110 at the current moment. The host temperature reflects the heat accumulation generated by the operation of the electronic components during the operation of the host 110 and the efficiency of the heat dissipation system. Accurate monitoring of the host temperature is essential to ensure the safe operation of the host 110, prevent damage due to overheating or overcooling, and optimize energy efficiency. The host is equipped with a built-in temperature sensor, such as a thermistor or an infrared temperature sensor, which monitors the temperature measurement value of the electronic components inside the host 110 at the current moment in real time. For example, in a high temperature environment in summer, after the user continuously uses the oral care device 10 in deep cleaning mode for 30 minutes, the host temperature is monitored to reach 45°C. For another example, in extremely cold areas, due to the low ambient temperature and the influence of the external environment, the host temperature is monitored to be -28°C.

[0087] The host temperature threshold range is an interval range of the temperature measurement threshold set for the performance of the electronic components inside the host 110, which is used to indicate the safe operation of the host 110. When the host temperature is not within the host temperature threshold range, the wireless charging module 130 is turned off by the host control unit 1110 to avoid wireless charging to the handle 120, further increasing the host temperature, causing damage to the host or performance degradation caused by overheating or overcooling of the host, and ensuring user safety and long-term reliability of the host. For example, if the host temperature is within the host temperature threshold range of -20 to 60°C, wireless charging is performed normally and the handle 120 is continuously charged. If the host temperature is below -20°C or above 60°C, it is not within the host temperature threshold range, and the wireless charging module 130 is turned off to avoid wireless charging to the handle 120.

[0088] To obtain the host temperature of the host, one optional method is to obtain the host temperature of the host at a preset frequency, and another optional method is to dynamically adjust the temperature measurement frequency according to the use status of the handle and historical temperature data to obtain the host temperature. For example, during high-load use of the host, the frequency of temperature monitoring is increased to ensure timely heat dissipation; while in standby or low-power mode, the temperature measurement frequency is reduced to save energy. This method can manage the thermal state of the host more flexibly and efficiently, improve user experience and optimize energy consumption, and is not limited here.

[0089] The wireless charging module 130 is turned off through the host control unit 1110. One optional way is to control the MOS switch through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the relay through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the pulse width modulation controller through the host control unit 1110 to turn off the wireless charging module 130. There is no limitation here.

[0090] In the embodiment of the present specification, when the host temperature is not within the host temperature threshold range, the wireless charging module 130 is turned off by the host control unit 1110, thereby avoiding charging the handle 120 when the host temperature is abnormal, further reducing safety hazards, reducing unnecessary power loss of the host 110, more effectively saving power, further reducing the cost of use, and further improving the product life of the oral care device 10.

[0091] See also Figure 2 In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110 and a host data transceiver unit 1120, and the handle 120 further includes a handle control unit 1210 and a handle data transceiver unit 1220;

[0092] The handle 120 is further used to generate a charging disconnection instruction through the handle control unit 1210 when the handle temperature is not within the handle temperature threshold range, and send the charging disconnection instruction to the host data transceiver unit 1120 through the handle data transceiver unit 1220;

[0093] The host 110 is further configured to respond to a charging trigger signal, receive a charging disconnection instruction through the host data transceiver unit 1120 , and shut down the wireless charging module 130 through the host control unit 1110 .

[0094] The handle temperature is the temperature measurement value of the electronic components inside the handle 120 at the current moment. The handle temperature reflects the heat accumulation generated by the operation of the electronic components during the operation of the handle 120 and the effectiveness of the heat dissipation system. Accurate monitoring of the handle temperature is essential to ensure the safe operation of the handle 120, prevent damage due to overheating or overcooling, and optimize energy efficiency. The handle is equipped with a built-in temperature sensor, such as a thermistor or an infrared temperature sensor, to monitor the temperature measurement value of the electronic components inside the handle 120 at the current moment in real time. For example, in a high temperature environment in summer, after the user continuously uses the oral care device 10 in deep cleaning mode for 30 minutes, it is detected that the handle temperature has reached 75°C. For another example, in extremely cold areas, due to the low ambient temperature and the influence of the external environment, the handle temperature is monitored to be -23°C.

[0095] The handle temperature threshold range is an interval range of the temperature measurement threshold set for the performance of the electronic components inside the handle 120, which is used to indicate the safe operation of the handle 120. When the handle temperature is not within the handle temperature threshold range, the handle control unit 1210 generates a charging disconnection instruction, and the handle data transceiver unit 1220 sends the charging disconnection instruction to the host data transceiver unit 1120. The host 110 responds to the charging trigger signal, receives the charging disconnection instruction through the host data transceiver unit 1120, and turns off the wireless charging module 130 through the host control unit 1110 to avoid wireless charging of the handle 120, further increase the handle temperature, and cause the handle to be overheated or overcooled, resulting in damage to the handle or performance degradation, to ensure user safety and long-term reliability of the handle. For example, if the handle temperature is within the handle temperature threshold range of 0 to 45°C, wireless charging is performed normally and the handle 120 is continuously charged. If the handle temperature is below 0°C or above 45°C, it is not within the handle temperature threshold range, and the wireless charging module 130 is turned off to avoid wireless charging of the handle 120.

[0096] The charging disconnection instruction is the instruction information for stopping triggering the host control unit 1110 to control the opening of the wireless charging module 130, and the charging disconnection instruction carries the handle temperature. For example. When the temperature sensor built into the handle 120 detects that the handle temperature is not within the handle temperature threshold range, the handle control unit 1210 automatically generates a charging disconnection instruction, which is sent to the 2.4G host data transceiver unit 1120 of the host 110 through the 2.4G handle data transceiver unit 1220. The host 110 responds to the charging trigger signal, receives the charging disconnection instruction through the handle data transceiver unit 1220, and turns off the wireless charging module 130 through the host control unit 1110, without manual intervention by the user.

[0097] To obtain the temperature of the handle, one optional method is to obtain the handle temperature of the handle at a preset frequency, and another optional method is to dynamically adjust the temperature measurement frequency according to the use status of the handle and historical temperature data to obtain the handle temperature. For example, during high-load use of the handle, the frequency of temperature monitoring is increased to ensure timely heat dissipation; while in standby or low-power mode, the temperature measurement frequency is reduced to save energy. This method can manage the thermal state of the handle more flexibly and efficiently, improve the user experience and optimize energy consumption, and is not limited here.

[0098] The wireless charging module 130 is turned off through the host control unit 1110. One optional way is to control the MOS switch through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the relay through the host control unit 1110 to turn off the wireless charging module 130. Another optional way is to control the pulse width modulation controller through the host control unit 1110 to turn off the wireless charging module 130. There is no limitation here.

[0099] In the embodiment of the present specification, when the handle temperature is not within the handle temperature threshold range, a charging disconnection instruction is generated by the handle control unit 1210, and the host 110 responds to the charging trigger signal, receives the charging disconnection instruction through the host data transceiver unit 1120, and shuts down the wireless charging module 130 through the host control unit 1110, thereby avoiding charging the handle 120 when the handle temperature is abnormal, further reducing safety hazards, reducing unnecessary power loss of the host 110, more effectively saving power, further reducing the cost of use, and further improving the product life of the oral care device 10.

[0100] See also Figure 2 In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110 and a host data transceiver unit 1120, and the handle 120 further includes a handle control unit 1210 and a handle data transceiver unit 1220;

[0101] The handle 120 is further used to obtain the handle power of the handle 120, generate a power update instruction through the handle control unit 1210, and send the power update instruction to the host data transceiver unit 1120 through the handle data transceiver unit 1220;

[0102] The host 110 is further used to receive a power update instruction through the host data transceiver unit 1120, and update the handle power based on the handle power.

[0103] The handle power is the remaining power of the battery built into the handle 120 at the current moment, which may include the handle power value and / or the handle power percentage, usually expressed in milliampere hours (mAh) and / or percentage (%), as an important indicator to measure the use status of the handle. It directly determines the available time of the handle and affects the user's usage planning and charging needs. For example, if the handle power is displayed as 800mAh, it means that the handle battery still has 800 mAh of power available for use; if the handle power is displayed as 20%, it means that the handle has only one-fifth of the total power left, and may need to be charged as soon as possible.

[0104] The power update command is generated by the handle control unit 1210 and sent to the host 110 through the handle data transceiver unit 1220. The purpose is to notify the host to update the current actual power information of the handle 120. This command contains the latest handle power data, which helps the host to grasp the power status of the handle in real time, so as to make decisions such as whether to turn on or off wireless charging. For example, when the handle power drops from 70% to 30%, the handle control unit 1210 detects this change and generates a power update command, carrying the new power data "30%" and sending it to the host. After receiving it, the host updates the handle power record to 30%, and judges whether the trigger condition of wireless charging is met. For example, if the power rises from 25% to 60% (assuming that the handle is charged by wire), a power update command will also be generated, carrying the "60%" information, so that the host can understand the change in the handle power and adjust the wireless charging mode.

[0105] An optional way to update the handle power based on the handle power is to determine the handle power as the handle power and display it to the user through an LED light or a display screen on the host 110.

[0106] In the embodiment of this specification, the handle 120 sends power data to the host 110 for update in real time. The host 110 intelligently controls the wireless charging accordingly to ensure that the handle has sufficient power, thereby improving the user experience. At the same time, it effectively manages energy, extends the product life, reduces unnecessary charging operations, and optimizes power utilization.

[0107] See also Figure 2 In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110 and a host data transceiver unit 1120, and the handle 120 further includes a handle data transceiver unit 1220;

[0108] The handle 120 sends the handle power to the host data transceiver unit 1120 via the handle data transceiver unit 1220;

[0109] The host 110 is also used to respond to the charging trigger signal, receive the handle power through the host data transceiver unit 1120, compare the handle power with the host power of the host 110, and determine whether the power balance condition is reached. If not, the wireless charging module 130 is turned on through the host control unit 1110 to transmit the power of the host 110 to the handle 120.

[0110] The handle data transceiver unit 1220 includes but is not limited to: a Bluetooth data transceiver unit, a WiFi data transceiver unit, a 2.4G data transceiver unit, a near-field data transceiver unit and a cable data transceiver unit.

[0111] The host data transceiver unit 1120 includes but is not limited to: a Bluetooth data transceiver unit, a WiFi data transceiver unit, a 2.4G data transceiver unit, a near-field data transceiver unit, and a cable data transceiver unit.

[0112] The host control unit 1110 is the core control module of the oral care device 10, which is responsible for monitoring and controlling the functions and operating status of the oral care device 10, including but not limited to: controlling the opening and closing of the wireless charging module 130, controlling the data transmission between the handle 120, and coordinating the collaborative work of various components. The host control unit 1110 is usually integrated with a microprocessor unit or a microcontroller unit, and can execute pre-programmed computer programs / instructions.

[0113] For example, the handle 120 sends the handle power (25%) to the host data transceiver unit 1120 through the handle data transceiver unit 1220. The host 110, in response to the charging trigger signal, receives the handle power (25%) through the host data transceiver unit 1120, compares the handle power (25%) with the host power (90%) of the host 110, determines that the power balance condition is not reached, and turns on the wireless charging module 130 through the host control unit 1110 to transfer the power of the host 110 to the handle 120.

[0114] In the embodiments of the present specification, the handle power status is transmitted to the host 110 in real time through stable communication between the handle data transceiver unit 1220 and the host data transceiver unit 1120, so that the host 110 can complete the power balance judgment in time and determine whether to turn on or off the wireless charging module 130 through the host control unit 1110, thereby saving power more immediately and effectively.

[0115] See also Figure 2 In an optional embodiment of the present specification, the host 110 is also used to compare the handle power and the host power of the host 110 to determine whether the power balance condition is reached when the handle power is less than or equal to the handle power threshold; or the host 110 is also used to turn off the wireless charging module 130 through the host control unit 1110 when the handle power is greater than the handle power threshold.

[0116] The handle power threshold is a charging threshold pre-set for the handle power. When the handle power is less than or equal to the handle power threshold, the handle power is compared with the host power of the host 110 to determine whether the power balance condition is met to prevent the handle 120 from being unusable due to power exhaustion. When the handle power is greater than the handle power threshold, the handle 120 has sufficient power, and the wireless charging module 130 is turned off in time to avoid wasting power on the host 110.

[0117] For example, when the handle power (25%) is less than or equal to the handle power threshold (30%), the host 110 compares the handle power (25%) with the host power (90%) of the host 110 to determine that the power balance condition has not been met.

[0118] For example, when the handle power level (35%) is greater than the handle power threshold (30%), the host 110 turns off the wireless charging module 130 through the host control unit 1110 .

[0119] In the embodiments of the present specification, the handle power status is transmitted to the host 110 in real time through stable communication between the handle data transceiver unit 1220 and the host data transceiver unit 1120, thereby promptly avoiding charging when the handle power is high, reducing unnecessary power loss of the host 110, and saving power more immediately and effectively.

[0120] In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110 and a host data transceiver unit 1120, and the handle 120 further includes a handle data transceiver unit 1220;

[0121] The handle 120 sends the handle temperature to the host data transceiver unit 1120 via the handle data transceiver unit 1220;

[0122] The host 110 is also used to respond to the charging trigger signal, receive the handle temperature through the host data transceiver unit 1120, and turn off the wireless charging module 130 through the host control unit 1110 when the handle temperature is not within the handle temperature threshold range.

[0123] The handle data transceiver unit 1220 includes but is not limited to: a Bluetooth data transceiver unit, a WiFi data transceiver unit, a 2.4G data transceiver unit, a near-field data transceiver unit and a cable data transceiver unit.

[0124] The host data transceiver unit 1120 includes but is not limited to: a Bluetooth data transceiver unit, a WiFi data transceiver unit, a 2.4G data transceiver unit, a near-field data transceiver unit, and a cable data transceiver unit.

[0125] The host control unit 1110 is the core control module of the oral care device 10, which is responsible for monitoring and controlling the functions and operating status of the oral care device 10, including but not limited to: controlling the opening and closing of the wireless charging module 130, controlling the data transmission between the handle 120, and coordinating the collaborative work of various components. The host control unit 1110 is usually integrated with a microprocessor unit or a microcontroller unit, and can execute pre-programmed computer programs / instructions.

[0126] For example, the handle 120 sends the handle temperature (75°C) to the host data transceiver unit 1120 through the handle data transceiver unit 1220. The host 110, in response to the charging trigger signal, receives the handle temperature (75°C) through the host data transceiver unit 1120, and turns off the wireless charging module 130 through the host control unit 1110 when the handle temperature (75°C) is not within the handle temperature threshold range (-20 to 60°C).

[0127] In the embodiments of the present specification, the temperature status of the handle is transmitted to the host 110 in real time through stable communication between the handle data transceiver unit 1220 and the host data transceiver unit 1120, thereby promptly avoiding charging of the handle 120 when the host temperature is abnormal, immediately and effectively reducing safety hazards and reducing unnecessary power loss of the host 110.

[0128] In an optional embodiment of the present specification, the host 110 further includes a host control unit 1110 and a host data transceiver unit 1120, and the handle 120 further includes a handle data transceiver unit 1220;

[0129] The handle 120 is also used to obtain the handle power of the handle 120 and send the handle power to the host data transceiver unit 1120 through the handle data transceiver unit 1220;

[0130] The host 110 is further used to receive the handle power through the host data transceiver unit 1120, and update the handle power based on the handle power.

[0131] The handle data transceiver unit 1220 includes but is not limited to: a Bluetooth data transceiver unit, a WiFi data transceiver unit, a 2.4G data transceiver unit, a near-field data transceiver unit and a cable data transceiver unit.

[0132] The host data transceiver unit 1120 includes but is not limited to: a Bluetooth data transceiver unit, a WiFi data transceiver unit, a 2.4G data transceiver unit, a near-field data transceiver unit, and a cable data transceiver unit.

[0133] The host control unit 1110 is the core control module of the oral care device 10, which is responsible for monitoring and controlling the functions and operating status of the oral care device 10, including but not limited to: controlling the opening and closing of the wireless charging module 130, controlling the data transmission between the handle 120, and coordinating the collaborative work of various components. The host control unit 1110 is usually integrated with a microprocessor unit or a microcontroller unit, and can execute pre-programmed computer programs / instructions.

[0134] One optional way to obtain the handle power of the handle 120 is to obtain the handle power of the handle at a preset frequency, and another optional way is to dynamically adjust the power measurement frequency according to the use status of the handle and historical power data to obtain the handle power. For example, during high-load use of the handle, the power monitoring frequency is increased; while in standby or low-power mode, the temperature measurement frequency is reduced. This method can manage the power status of the handle more flexibly and efficiently.

[0135] The handle 120 includes a storage unit for recording the current handle power, and the storage unit may be built into the handle control unit 1210 or may be external to the handle control unit 1210. The storage unit includes but is not limited to: registers, non-volatile memory (Non-Volatile Memory, such as EEPROM) and flash memory.

[0136] An optional way to update the handle power based on the handle power is to use the handle power to update the current handle power recorded in the storage unit.

[0137] For example, the handle 120 obtains the handle power of the handle 120 according to a preset frequency, and sends the handle power (25%) to the host data transceiver unit 1120 through the handle data transceiver unit 1220. The host 110 receives the handle power (25%) through the host data transceiver unit 1120, and uses the handle power (25%) to update the current handle power (22%) recorded in the storage unit.

[0138] In the embodiments of this specification, the real-time recording and updating of the handle power is completed through the stable communication between the handle data transceiver unit 1220 and the host data transceiver unit 1120, thereby realizing the timely monitoring of the handle power.

[0139] See also Figure 3 , Figure 3 FIG. 1 shows a schematic diagram of the structure of another oral care device provided by an embodiment of the present specification. Figure 3 As shown:

[0140] In an optional embodiment of the present specification, the oral care device further includes a sensor group 140 , the sensor group 140 includes a first sensor unit 1410 connected to the host 110 and a second sensor unit 1420 connected to the handle 120 ;

[0141] It is also used to generate a charging trigger signal when the distance between the first sensor unit 1410 and the second sensor unit 1420 is smaller than the trigger distance.

[0142] The sensor group 140 is a set of sensor units for distance perception, and includes a first sensor unit 1410 connected to the host 110 and a second sensor unit 1420 connected to the handle 120 .

[0143] The first sensor unit 1410 is a sensor unit connected to the host 110, and the first sensor unit 1410 is used to cooperate with the second sensor unit 1420 to monitor the change of the magnetic field. The first sensor unit 1410 can be a Hall element or a magnetic component, and the magnetic component can be a magnet element, or an excitation or magnetic sensing element such as a coil, which can provide a changing magnetic field. The first sensor unit 1410 can be arranged on the host 110, or can be external to the host 110, which is not limited here.

[0144] The second sensor unit 1420 is a sensor unit connected to the handle 120, and is used to cooperate with the first sensor unit 1410 to monitor changes in the magnetic field. The second sensor unit 1420 can be a Hall element or a magnetic component, and the magnetic component can be a magnet element, or an excitation or magnetic sensing element such as a coil, which can provide a changing magnetic field. The second sensor unit 1420 can be arranged on the handle 120, or can be externally placed on the handle 120, which is not limited here.

[0145] The spacing between the first sensor unit 1410 and the second sensor unit 1420 is the straight-line distance between the first sensor unit 1410 and the second sensor unit 1420 during the process of attaching the handle 120 to the host 110. When the handle 120 is attached to the host 110, this distance can be fixed or a small range of variation allowed by the design. This spacing is an important parameter for sensor arrangement and is directly related to the synchronization of sensor data, measurement accuracy, and the overall functional performance of the system.

[0146] As an example, the trigger spacing is a critical value of the straight-line distance for triggering the Hall effect. Once the spacing between the first sensor unit 1410 and the second sensor unit 1420 is smaller than the critical value, the conductors of the sensor units in the sensor group 140 will generate a voltage difference perpendicular to the direction of the current and the magnetic field, thereby generating a Hall signal, which is a charging trigger signal.

[0147] In one example, the trigger spacing is a critical value of the linear distance for receiving laser light. Once the spacing between the first sensor unit 1410 and the second sensor unit 1420 is less than the critical value, the sensor units in the sensor group 140 will receive a certain intensity of reflected laser light, generating a laser proximity signal, which is a charging trigger signal.

[0148] In one example, the triggering distance is a critical value of the straight-line distance for receiving ultrasonic waves. Once the distance between the first sensor unit 1410 and the second sensor unit 1420 is less than the critical value, the sensor units in the sensor group 140 will receive ultrasonic waves of a certain intensity that are reflected back, and generate an ultrasonic proximity signal, which is a charging trigger signal.

[0149] The charging trigger signal is a Hall signal used to control the start of the wireless charging module 130. When the Hall effect occurs, the conductor of the sensor unit in the sensor group 140 generates a voltage difference perpendicular to the direction of the current and the magnetic field, generating a Hall signal, which is a charging trigger signal.

[0150] In response to the charging trigger signal, the wireless charging module 130 is turned on to transmit the power of the host 110 to the handle 120. An optional method is: in response to the charging trigger signal, the wireless charging module 130 is turned on to transmit the power of the host 110 to the handle 120 through the MOS switch. Another optional method is: in response to the charging trigger signal, the wireless charging module 130 is turned on to transmit the power of the host 110 to the handle 120 through a relay. Another optional method is: in response to the charging trigger signal, the wireless charging module 130 is turned on to transmit the power of the host 110 to the handle 120 through a pulse width modulation (PWM) controller. There is no limitation here.

[0151] In the embodiment of this specification, when the distance between the first sensor unit 1410 and the second sensor unit 1420 is less than the Hall effect triggering distance, the Hall effect is triggered to generate a charging trigger signal, and in response to the charging trigger signal, the wireless charging module 130 is automatically turned on to transmit the power of the host 110 to the handle 120, which effectively saves power, reduces the cost of use and safety hazards, and improves the product life of the oral care device 10. When the handle 120 is not placed, the host 110 turns off the wireless charging module 130, which can prevent the handle 120 from being frequently charged, and at the same time avoid the wireless charging module 130 being in the turned-on state and consuming power.

[0152] In an optional embodiment of the present specification, the host 110 further includes a handle placement position;

[0153] The first sensor unit 1410 is a first magnetic member, the second sensor unit 1420 is a Hall element, and the magnet unit is arranged at the handle placement position;

[0154] When the handle 120 is placed in the handle placement position, the distance between the Hall element and the first magnetic member is smaller than the Hall effect triggering distance.

[0155] There is an electrical connection between the Hall element and the host 110. When the Hall effect occurs, a voltage difference perpendicular to the direction of the current and the magnetic field is generated, generating a Hall signal, which is a charging trigger signal, and is sent to the host 110 through the electrical connection. The host 110 controls the wireless charging module 130 to start in response to the charging trigger signal.

[0156] The first magnetic member can be arranged on the handle 120, or can be placed outside the handle 120, including but not limited to: neodymium iron boron (NdFeB) magnet, samarium cobalt (SmCo) magnet, aluminum nickel cobalt (AlNiCo) magnet, excitation coil. Taking the arrangement on the handle 120 as an example, an optional way is: the first magnetic member is arranged on the back of the handle 120. A further optional way is: the first magnetic member is fixed on a magnet fixing frame, and the magnet fixing frame is arranged on one side of the handle near the back of the handle. When the handle 120 is connected to the handle placement position of the host 110, the distance between the Hall element and the first magnetic member is less than the Hall effect trigger distance.

[0157] In the embodiment of the present specification, when the distance between the Hall element and the first magnetic part is smaller than the Hall effect trigger distance, a charging trigger signal is generated by the Hall element, and the wireless charging module is automatically turned on to transmit the power of the host to the handle, thereby realizing intelligent wireless charging, simplifying the charging operation, improving efficiency and safety, and optimizing the user experience.

[0158] In an optional embodiment of the present specification, the host 110 further includes a second magnetic member, and the second magnetic member and the first magnetic member are used to attach the handle 120 to the handle placement position of the host 110. The first magnetic member is a magnet, and the first magnetic member can trigger the first sensor unit 1410, and can cooperate with the second magnetic member to magnetically adsorb the handle 120 to the handle placement position of the host 110. The second magnetic member is a magnet or a material that can be magnetically attracted by a magnet, such as an iron sheet.

[0159] In an optional embodiment of the present specification, the handle 120 further includes a third magnetic member, and the second magnetic member and the third magnetic member are used to attach the handle 120 to the handle placement position of the host 110. The second magnetic member and the third magnetic member can be arranged to detachably connect the handle 120 to the host 110 at any one of a plurality of desired positions relative to the host 110. The second magnetic member and the third magnetic member can both be magnets, or one of the second magnetic member and the third magnetic member is a magnet, and the other is a substance that can be adsorbed by a magnet, such as an iron sheet.

[0160] The second magnetic member is a magnet or a material that can be magnetically attracted and arranged on the main unit 110, including but not limited to: neodymium iron boron (NdFeB) magnet, samarium cobalt (SmCo) magnet and aluminum nickel cobalt (AlNiCo). One optional way is to arrange it at the bottom of the main unit 110 to ensure stable adsorption; another optional way is to install it on the side of the main unit 110 to facilitate adsorption with the handle 120 from different angles; another optional way is to design it into a detachable structure to facilitate users to adjust or replace it as needed.

[0161] The third magnetic member is a magnet or a material that can be magnetically attracted and arranged on the handle 120, including but not limited to: neodymium iron boron (NdFeB) magnet, samarium cobalt (SmCo) magnet and aluminum nickel cobalt (AlNiCo). One optional way is to embed it on the back of the handle 120 and directly attach it to the host 110 by magnetic attraction; another optional way is to set it at the bottom of the handle 120 to facilitate adsorption with the host 110 from different angles; another optional way is to wrap it with low-loss materials to reduce interference with other circuit components in the handle.

[0162] In the embodiments of the present specification, the second magnetic component and the third magnetic component are both magnets, and the second magnetic component and the third magnetic component are arranged relative to each other at their opposite ends, for example, the S pole of the third magnetic component on the handle 120 and the N pole of the second magnetic component on the main unit 110 are arranged relative to each other, and the handle 120 and the main unit 110 are detachably connected through the magnetic adsorption effect between the second magnetic component and the third magnetic component, and the handle 120 is adjustably and firmly and flexibly connected to the handle placement position of the main unit 110 through magnetic attachment, thereby improving the convenience and stability of the oral care device 10 in use.

[0163] See also Figure 4 , Figure 4 FIG. 1 shows a structural diagram of another oral care device provided by an embodiment of the present specification, such as Figure 4 As shown:

[0164] The oral care device 10 includes a main body 110 , a handle 120 , a wireless charging module 130 and a sensor group 140 .

[0165] The host 110 includes a host control unit 1110 and a host data transceiver unit 1120 .

[0166] The handle 120 includes a handle control unit 1210 and a handle data transceiver unit 1220 .

[0167] The wireless charging module 130 includes a wireless charging transmitting unit and a wireless charging receiving unit, wherein the wireless charging transmitting unit is arranged on the host 110 and the wireless charging receiving unit is arranged on the handle 120 .

[0168] The sensor group 140 includes a Hall element disposed on the main body 110 and a first magnetic member disposed on the handle 120 .

[0169] The MOS switch operates at a steady current under the operating voltage.

[0170] The workflow is as follows:

[0171] When the handle 120 is removed from the host 110 and the distance between the Hall element and the first magnetic member is greater than the Hall effect triggering distance, the host 110 automatically wakes up.

[0172] The user only needs to touch the power button on the handle 120 to start the device.

[0173] The handle 120 obtains the handle power level, and when the handle power level is less than or equal to the handle power threshold, generates a charging instruction through the handle control unit 1210, and sends the charging instruction to the host data transceiver unit 1120 through the handle data transceiver unit 1220.

[0174] After use, the handle 120 is placed back to the handle placement position of the host 110, and a charging trigger signal is generated when the distance between the Hall element and the first magnetic member is smaller than the Hall effect trigger distance.

[0175] In response to the charging trigger signal, the host 110 receives the charging instruction through the host data transceiver unit 1120, compares the power of the handle with the host power of the host 110, and determines whether the power balance condition is met.

[0176] If not, the host control unit 1110 controls the MOS switch to turn on the wireless charging module 130 to transmit the power of the host 110 to the handle 120 .

[0177] As the power of the host gradually decreases, the power of the handle gradually increases. When the power of the host and the power of the handle reach a power balance condition, the wireless charging module 130 is turned off.

[0178] The handle 120 obtains the handle power level, and when the handle power level is greater than the handle power threshold, generates a charging disconnection instruction through the handle control unit 1210, and sends the charging disconnection instruction to the host data transceiver unit 1120 through the handle data transceiver unit 1220.

[0179] In response to the charging trigger signal, the host 110 receives the charging disconnection instruction through the host data transceiver unit 1120 , and controls the MOS switch through the host control unit 1110 to turn off the wireless charging module 130 .

[0180] During the entire charging balancing process, the handle 120 obtains the handle temperature at a preset frequency. When the handle temperature is not within the handle temperature threshold range, a charging disconnection instruction is generated through the handle control unit 1210, and the charging disconnection instruction is sent to the host data transceiver unit 1120 through the handle data transceiver unit 1220. The host 110 responds to the charging trigger signal, receives the charging disconnection instruction through the host data transceiver unit 1120, controls the MOS switch through the host control unit 1110, and turns off the wireless charging module 130.

[0181] During the entire charging balancing process, the host 110 obtains the host temperature of the host 110 at a preset frequency. When the host temperature is not within the host temperature threshold range, the host control unit 1110 controls the MOS switch to turn off the wireless charging module 130.

[0182] See also Figure 5 , Figure 5 A flowchart of a charging method for an oral care device provided by an embodiment of the present specification is shown. The method is applied to the oral care device, which further includes a host, a handle, and a wireless charging module. The host includes a fluid reservoir and a pump fluidically connected to the fluid reservoir. The handle is fluidically connected to the host, and the handle is adjustably connected to the host via a magnetic attachment structure. The method includes the following specific steps:

[0183] Step 502: In response to the charging trigger signal, obtaining the handle power of the handle;

[0184] Step 504: Compare the power of the handle with the power of the host to determine whether the power balance condition is met;

[0185] Step 506: If not, turn on the wireless charging module to transfer the power of the host to the handle.

[0186] The embodiments of this specification are similar to the above Figure 1 The embodiments of the specification are based on the same inventive concept. The specific contents of steps 502 to 506 can be found in the above-mentioned embodiments of the specification, which will not be repeated here.

[0187] In the embodiment of the present specification, in response to the charging trigger signal, the power level of the handle is compared with the power level of the host. If the power balance condition is not reached, the wireless charging module is automatically turned on to transfer the power of the host to the handle, thereby avoiding the continuation of wireless charging when it is not suitable for charging, effectively saving power, reducing the use cost and safety hazards, and improving the battery life of the product.

[0188] Figure 6 A schematic diagram of a charging method for an oral care device provided in one embodiment of the present specification is shown. Figure 6 As shown:

[0189] 1. At the beginning, whether the host detects the Hall effect: there is a handle charging area on the host. If the handle is in this area, the host Hall sensor will recognize the level change, thereby determining whether the handle is in the handle placement position of the host and completing the attached charging.

[0190] 2. If not, the handle is not in the handle placement position of the host and charging cannot be completed: If the handle is not in the handle placement position of the host, there is no need to perform charge balancing to reduce host battery consumption.

[0191] 3. Send charging trigger signal to the handle: After the host recognizes the change of the Hall signal, it will send a charging trigger signal to the handle. The host and handle communication uses a 2.4G RF communication module.

[0192] 4. Whether the power of the handle is less than 30%: Determine whether the power of the handle meets the prerequisite for charging balance.

[0193] 5. Whether the host power is greater than 50%: Determine whether the host power meets the prerequisite for charging balance.

[0194] 6. Start the charge balancing function: Start the charge balancing function.

[0195] 7. Turn on the wireless charging module to transfer the power of the host to the handle: the power of the charging balancing function is provided by the host battery, and the host emits an alternating electromagnetic field through the wireless charging transmitting unit to charge the handle.

[0196] 8. The host display screen updates to show the handle power level: The host display screen will show the real-time power level of the host.

[0197] 9. The handle enters the charging state: When the host emits an alternating electromagnetic field, the handle will enter the charging state.

[0198] 10. Whether the host receives the handle message: The host is in the RF receiving state by default. If the handle sends a message, the host will update the handle power. If the host does not receive the handle data, it means that there is no data change in the handle.

[0199] 11. Update the handle power: If the handle sends a message, the host will update the handle power.

[0200] 12. Whether the host detects the Hall effect: The host will detect the Hall effect in real time to ensure that the handle is in the handle placement position of the host and complete charging. If the handle is not in the handle placement position of the host, the host will stop emitting the alternating electromagnetic field through the wireless charging transmitting unit to save the host battery power.

[0201] 13. Whether the handle temperature is within the handle temperature threshold: The host updates the handle temperature and determines the handle charging temperature. If the current handle charging temperature is between 0 and 45°C, the handle NTC (Negative Temperature Coefficient) is in a normal state. On the contrary, if the handle NTC is in an abnormal state, the host will stop emitting an alternating electromagnetic field through the wireless charging transmitter unit.

[0202] 14. Whether the host temperature is within the host temperature threshold: If the host temperature is between -20 and 60°C, the host is in a normal state. Otherwise, if the host NTC is in an abnormal state, the host will stop emitting an alternating electromagnetic field through the wireless charging transmitter unit.

[0203] 15. Compare the power of the handle with the power of the host to determine whether the power balance condition is met: if the power of the handle is greater than or equal to the power of the host, it means that the power of the handle and the host are in power balance, and the host will stop emitting the alternating electromagnetic field through the wireless charging transmitting unit.

[0204] 16. Completion of charging equalization function: If the charging equalization function is completed, the host will stop emitting the alternating electromagnetic field through the wireless charging transmitting unit to save the host battery power.

[0205] 17. Exit the charge balancing function: If you exit the charge balancing function, the host will stop emitting the alternating electromagnetic field through the wireless charging transmitter unit to save the host battery power.

[0206] 18. Turn off the wireless charging module to save host battery power.
