Common household water flossers are usually powered by batteries and powered by motors. During the use of the water flosser, the battery gradually discharges from a fully charged state, and the battery voltage gradually decreases until it is cut off. This voltage change will directly affect the voltage at both ends of the motor, slowing down the motor speed and reducing the output power, which will cause users to clearly feel the problem of reduced water pressure output by the water flosser when the battery power is low.

[0022] 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.

[0023] 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.

[0024] The main solution of the embodiment of the present application is that the oral irrigator can select the corresponding driving mode according to the driving signal triggered by the user, and drive the oral irrigator by dynamically adjusting the driving parameters according to the power supply voltage of the driving component, so that the oral irrigator outputs a pulsed water flow at a constant water pressure. In this way, the problem that the oral irrigator needs a certain amount of time to adjust to the preset constant water pressure output water flow after switching the mode can be solved, and there is a large hysteresis.

[0025] In this embodiment, for the convenience of description, the following description is made by taking the identification of the water flosser as the execution subject.

[0026] As the living standards improve, more and more people are starting to use water flossers to clean their teeth. Common household water flossers are usually powered by batteries and powered by motors. During the use of the water flosser, the battery gradually discharges from a fully charged state, and the battery voltage gradually decreases until it is cut off. This voltage change will directly affect the voltage at both ends of the motor, slowing down the motor speed and reducing the output power, which will cause users to clearly feel that the water pressure output of the water flosser is weakened when the battery power is low.

[0027] In order to solve this problem, the existing constant water pressure water flosser collects the voltage at both ends of the motor and feeds it back to the control unit. The control unit adjusts the duty cycle of the drive signal based on the feedback voltage information and the target voltage value, so that the voltage output by the drive unit remains stable. This design can ensure that the water flosser can still provide stable water pressure output when the battery voltage changes to a certain extent.

[0028] However, in order to meet the various needs of users, water flossers usually have multiple working modes. After switching modes, existing constant water pressure water flossers need a certain amount of time to adjust to the preset water pressure, which has a large hysteresis.

[0029] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a water flosser, etc. The water flosser is taken as an example to illustrate this embodiment and the following embodiments.

[0030] Based on this, the embodiment of the present application provides a constant water pressure control method, which is applied to a water flosser. The water flosser is preset with multiple drive modes, and multiple drive parameters are set in the drive mode. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the constant water pressure control method of the present application.

[0031] In this embodiment, the constant water pressure control method includes steps S100 to S300: Step S100, selecting a corresponding driving mode in response to a sensing signal triggered by a user; Step S200, continuously acquiring the power supply voltage of the driving component, and dynamically adjusting the driving parameters according to the power supply voltage and the control relationship mapping table in the corresponding driving mode; Step S300: outputting a pulsed water flow with a constant water pressure preset in a corresponding driving mode according to the driving parameters.

[0032] It should be noted that in this method, a control system is provided in the oral irrigator, and the control system continuously monitors the sensing signal triggered by the user. When the user triggers the sensor of the oral irrigator, the control system can convert a series of functional instructions according to the sensing signal, thereby performing a series of state transitions such as turning on or off, driving, or selecting a corresponding driving mode according to the functional instructions.

[0033] It should also be noted that the sensing signal can be implemented through multiple sensors, which can be a touch screen, a membrane button, a mechanical button, a touch button and an external sensor (such as a wireless communication module, the control system converts the sensing signal sent by the external sensor into a functional instruction), or it can be implemented through a single sensor. Specifically, the sensor can be set to a button. When the user presses the button for a long time for a predetermined time, the button outputs a sensing signal with a conduction time reaching a predetermined threshold to turn on or off the device, and within a specified time (such as 3S), the user short presses the button multiple times to select multiple driving modes (such as a gentle driving mode, a normal driving mode and a strong driving mode). When the control system inputs the button in the above manner within the specified time, the control system selects the corresponding driving mode for driving according to the action of triggering the button; the sensor can also be passed through multiple buttons, so that the control system can distinguish the functional instructions from multiple sensing signals to achieve more precise control and give users a more personalized experience.

[0034] It should be additionally explained that the driving mode can be preset in advance, or it can be adjusted or increased internally, for example, the sensor can be set as a touch screen, the internal driving mode and driving parameters can be set through the touch screen, and the internally stored data can be changed or created in the storage medium to control the creation of the driving mode and the setting of the driving parameters in the various driving modes.

[0035] In step S200, the power supply voltage of the driving component 4 is continuously acquired, and the driving parameters are dynamically adjusted according to the power supply voltage and the corresponding driving mode. A voltage detection component 5 is also provided in the water flosser. The voltage detection component 5 continuously detects the power supply voltage of the driving component 4, and dynamically adjusts the driving parameters according to the control relationship between the power supply voltage and the driving parameters, that is, the control relationship mapping table.

[0036] In step S300, according to the driving parameters, in the step of outputting a pulse water flow with a preset constant water pressure under a corresponding driving mode, the driving signal is modulated according to the driving parameters adjusted in real time, and the driving component receives the driving signal for driving, so that the driving component 4 can output a pulse water flow with a preset constant water pressure under the corresponding driving mode.

[0037] The oral irrigator of the present application selects the corresponding driving mode according to the driving signal triggered by the user, and drives the oral irrigator by dynamically adjusting the driving parameters according to the power supply voltage of the driving component, so that the oral irrigator outputs a pulsed water flow at a constant water pressure. In this way, the problem that the oral irrigator needs a certain amount of time to adjust to the preset constant water pressure output water flow after switching the mode can be solved, and there is a large hysteresis.

[0038] Reference Figure 2 In a feasible implementation manner, step S100 may include steps S110 to S130: Step S110, obtaining a first sensing signal emitted by the first sensor 2 and a second sensing signal emitted by the second sensor 3; In this step, the sensor is configured to include a first sensor 2 and a second sensor 3. When the user triggers the first sensor 2, a first sensing signal is generated. When the user triggers the second sensor 3, a second sensing signal is generated. The control system generates different functional instructions by receiving the first sensing signal and the second sensing signal at different time intervals.

[0039] Step S120, entering a power-on state in response to the first sensing signal; In this step, when the control system is in the off state and receives the first sensing signal, the control system is switched to the on state, and when the water flosser is in the on state and the control system does not receive the first sensing signal and the second sensing signal within a specified time (such as 10 seconds), the control system is switched from the on state to the off state, thereby shutting down the internal components. In this way, power consumption can be effectively reduced.

[0040] Step S130, selecting a corresponding driving mode in response to the second sensing signal, and entering a working state according to the selected driving mode in response to the first sensing signal.

[0041] In this step, when the control system is in the power-on state, a selection is made among multiple preset driving modes through the received second sensing signal, and after the selection is completed, a driving signal is output to the driving component 4 according to the driving parameters in the selected driving mode through the received first sensing signal, so that the control system enters the working state, and the pulse water flow with constant water pressure output by the water flosser is determined according to the driving parameters, wherein the driving parameters include frequency parameters, duty cycle parameters, sending duration parameters and amplitude parameters.

[0042] In summary, the constant water pressure control method can conveniently achieve low-power operation through two sensors, and can select corresponding driving modes to provide users with different usage experiences.

[0043] Reference Figure 3 In a feasible implementation manner, the step of continuously acquiring the power supply voltage of the driving component and dynamically adjusting the driving parameters according to the power supply voltage in accordance with the control relationship mapping table in the corresponding driving mode also includes: Step S210: continuously acquiring the supply voltage of the driving component through the voltage detection component, and dynamically adjusting the driving parameters according to the control relationship mapping table.

[0044] Specifically, in the working state, the control system dynamically adjusts the duty cycle parameter in the driving parameter in real time according to the preset control relationship mapping table by using the voltage value of the power supply voltage detected by the voltage detection component 5, and the control system dynamically modulates and sends the driving signal according to the driving parameter. It can be understood that in some embodiments of the present application, the control system also modulates the driving signal by adjusting the frequency parameter, the transmission duration parameter, and the amplitude parameter in the selected driving mode.

[0045] In the present application, the driving component can be a motor. The frequency of the driving signal determines the working mode of the motor and thus determines the frequency of the pulsed water flow generated by the water flosser, that is, the "impact frequency" of the water flosser. High-frequency driving signals can make the water flow more continuous and smooth, while low-frequency driving signals will make the water flow have a noticeable pulse feeling. Under high-frequency parameters, the water flow is denser and smoother, suitable for gentle cleaning. Under low-frequency parameters, the pulsed water flow is more impactful and more suitable for deep cleaning or removing stubborn dirt.

[0046] The sending duration refers to the duration of each pulse signal, that is, the duty cycle of the drive signal. In a pulse drive system, the duty cycle determines the duration of each pulse signal being "on" or "off". With a long sending duration, each pulse signal lasts longer, and the motor will maintain water flow output for a longer time, with a stronger impact force. With a short sending duration, the water flow output time is short, the impact force is weakened, and it is more suitable for gentle flushing of sensitive areas.

[0047] The amplitude of the drive signal usually indicates the amplitude of the voltage fluctuation, which directly affects the torque generated by the motor, and thus affects the impact force of the water flow. High amplitude parameters correspond to stronger water flow impact force, which can clean teeth and gums more effectively. Low amplitude parameters have less impact force and are suitable for sensitive people.

[0048] Reference Figure 4 In a feasible implementation manner, the step of outputting a pulsed water flow with a preset constant water pressure in a corresponding driving mode according to the driving parameters comprises: Step S310, modulating a driving signal according to the driving parameter adjusted in real time; In step S320, the driving component 4 receives the driving signal to drive and output a pulse water flow with a constant water pressure preset in the corresponding driving mode.

[0049] Specifically, the control system modulates the drive signal according to the real-time adjusted drive parameters to ensure that the drive signal can accurately reflect the required drive mode and constant water pressure requirements. When the drive component 4 receives these modulated drive signals, it responds to them to output a pulse water flow with a constant water pressure preset in the drive mode.

[0050] Reference Figure 5 In a feasible implementation manner, the water flosser is further provided with a prompt component 6, and the control method of the electric toothbrush further includes: Step S400, in response to the first trigger signal and / or the second sensing signal, generating a corresponding prompt signal to control the prompt component 6 to prompt the user.

[0051] In this step, the prompt component 6 can be set to one or more prompt components 6 such as a screen, multiple LED lights and a voice prompt module. Whenever the main controller 1 receives the first trigger signal and / or the second sensing signal, the control system in the main controller 1 receives and processes it to generate a corresponding prompt signal. The prompt component prompts the user of the current state of the control system according to the prompt signal. For example, when the prompt component 6 is set to a screen, the prompt component 6 generates corresponding multimedia content according to the sent prompt signal for the user to understand the current state of the control system; or when the prompt component 6 is set to multiple LED lights, the prompt component 6 controls the multiple LED lights to flash or stay on according to the sent prompt signal, and controls the voice prompt module to give a voice prompt of the current state of the control system, thereby prompting the user.

[0052] This diversified prompting method not only improves the user experience, but also enhances the interactivity and usability of the system. Both novice users and experienced operators can quickly understand the status of the control system through the prompt component 6, so as to make correct operation decisions. This design not only improves the user experience, but also enhances the interactivity and usability of the system, bringing users a more convenient and efficient operation experience.

[0053] Reference Figure 6 As shown in Table 1, in a feasible implementation manner, the step of selecting a corresponding driving mode in response to a sensing signal triggered by a user also includes S001-S004.

[0054] Step S001, creating a control relationship mapping table according to the supply voltage range V1 to V2, the step value V3 and the preset water pressure; Step S002, selecting a power supply voltage V1, adjusting the duty cycle according to the power supply voltage so that the oral irrigator outputs a pulsed water flow with a preset water pressure, and recording the current duty cycle; Step S003, lowering the supply voltage from V1 by a step value V3 to a supply voltage of V1-V3, adjusting the duty cycle so that the oral irrigator outputs a pulsed water flow with a preset water pressure, and recording the current duty cycle; Step S004, gradually lowering the supply voltage to V2, and recording the duty cycle numerical parameters corresponding to the supply voltage in sequence.

[0055] See also Figure 6 In this step, the present invention creates a control relationship mapping table that can accurately map the relationship between the control parameters of the dental floss device and physical quantities such as voltage and water pressure according to the power supply voltage range V1 to V2, the step value V3 and the preset water pressure, so that the dental flosser can output a constant water pressure for dental flossing under different voltages.

[0056] Referring to Table 1, in this application, within the supply voltage range of V1 to V2, a series of discrete voltage points are selected according to the step value, and the difference between each point is determined by the step value V3. These voltage points constitute an arithmetic progression with a tolerance of the step value, which can be expressed as V=V1-(n-1)V3, V∈(V1, V2). Then, the values ​​of the drive parameters are adjusted accordingly at different voltage points, so as to drive the motor to output a water flow with a constant water pressure, and a control relationship mapping table is created according to the relationship between different supply voltages and the corresponding drive parameters.

[0057] The following is a detailed explanation using the duty cycle as an example: Specifically, first adjust the duty cycle under V1 to drive the motor to output a water flow with a preset water pressure, and record the voltage and duty cycle at this time.

[0058] Then, the supply voltage is reduced from V1 by a step value V3 to a supply voltage of V1-V3, and the duty cycle is adjusted so that the water flosser outputs a preset constant water pressure, and the voltage and duty cycle at this time are recorded.

[0059] Then, the power supply voltage is gradually reduced to V2 according to the step value, and the duty cycle numerical parameters corresponding to the power supply voltage are recorded step by step in sequence to obtain a power supply voltage-duty cycle control relationship mapping table.

[0060] Table 1: Supply voltage-duty cycle control relationship mapping table

[0061] It can be understood that in the present application, the power supply voltage-duty cycle control relationship mapping table in Table 1 includes two working modes. In the two working modes, the control parameters corresponding to the same power supply voltage are inconsistent. In this way, different flushing effects can be achieved according to the setting of different working modes.

[0062] It should be noted that when the frequency parameter, the transmission duration parameter or the amplitude parameter is selected as the driving parameter, the corresponding control relationship mapping table created is the power supply voltage-frequency control relationship mapping table, the power supply voltage-transmission duration control relationship mapping table or the power supply voltage-amplitude control relationship mapping table. The step value V3 can be any value of 0.1, 0.2, 0.3, 0.4, 0.5 or 0.01-0.5. It can be understood that the smaller the step value, the finer the control of the motor according to the control relationship mapping table. In this way, the water flosser can dynamically adjust the duty cycle according to the voltage value detected by the voltage detection component.

[0063] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the constant water pressure control method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.
