[0035] The water flosser is an auxiliary tool for cleaning the oral cavity. It mainly uses the impact force of a high-speed water column ejected under a certain pressure to achieve cleaning. Therefore, stable water pressure control plays a very critical role in the cleaning effect of the water flosser. Since the output voltage of the battery changes with the power, it is difficult to stabilize the motor output power of the water flosser, which makes it difficult to maintain a stable output water pressure of the water flosser, and users are prone to discomfort during use. Therefore, how to confirm the relationship between the water pressure output by the water flosser and the output voltage of the battery has become a technical problem that needs to be solved at present.
[0036] Therefore, reference Figure 1 and Figure 4 The present invention provides a method for testing a water flosser, which is applied to a water flosser testing system. The water flosser testing system includes a pressure detection unit for detecting the output water pressure of the water flosser and a voltage detection unit for detecting the output voltage of a battery of the water flosser. The method includes:
[0037] Step S100: controlling the water flosser to spray liquid to the pressure detection unit;
[0038] Step S200: Acquire multiple pressure detection signals and multiple voltage detection signals of the output voltage of the battery of the water flosser;
[0039] Step S300: confirming the relationship between the water pressure output by the water flosser and the output voltage of the battery of the water flosser according to the multiple pressure detection signals and the multiple voltage detection signals.
[0040] It is important to understand that different models of water flossers have different water pressure outputs when they are working. Furthermore, different models of water flossers have different battery output voltages when they are working. As the battery in the water flosser continues to work, its output voltage will gradually decrease, which will also cause the water pressure output by the water flosser to change. Therefore, the water pressure output by the water flosser is related to the output voltage of the battery.
[0041] In this embodiment, the water flosser detection system needs to use a device with a closed chamber and liquid circulation as a test environment for directly testing the operation of the water flosser. Among them, the water flosser can establish a communication connection with the control device in the water flosser test system through the corresponding communication line. The communication interface and communication line of the water flosser must be waterproof to avoid line damage caused by the liquid sprayed when the water flosser is working. The water flosser test system can control the operation of the water flosser in real time through the control device, and obtain the voltage output by the water flosser battery through the communication line. In this way, the working state of the water flosser can be conveniently controlled, and the output voltage of its battery can be detected, without the need to disassemble the water flosser body for detection and control. Specifically, this communication connection method needs to be determined for the communication connection interface of the water flosser. For example, the communication connection interface of the water flosser is type-c, Lightning, etc. For water flossers without a communication interface, it is necessary to manually disassemble the shell of the water flosser, establish a communication connection between the main control circuit and the control device in the water flosser, and establish an electrical connection between the voltage detection unit and the water flosser battery. In addition, a protective shell with reserved connection openings and output openings of the water flosser nozzle is required to protect the water flosser and the connected test circuit. Furthermore, the water flosser uses a semi-open water tank in the water flosser test system, that is, the water flosser test system will recover the liquid sprayed by the water flosser when it is working, and input it into the semi-open water tank in time to maintain the long-term test of the water flosser.
[0042] In this embodiment, the pressure detection unit can be implemented by a strain gauge pressure sensor, a ceramic pressure sensor, a capacitive pressure sensor, etc. Specifically, the pressure detection unit adopts a planar structure to stably receive the water pressure sprayed by the water flosser. The water flosser test system is electrically connected to the main control circuit in the water flosser through the control device, and then controls the water flosser to work, so that the water flosser directly sprays the liquid on the pressure detection unit, so that the pressure detection unit can more accurately obtain the water pressure output by the water flosser and output a pressure detection signal to the control device. At the same time, the control device will also detect the output voltage of the water flosser battery through the voltage detection unit. Among them, the voltage detection unit can detect the output voltage of the battery by connecting the voltage detection circuit through a wire to obtain the output voltage of the battery. By repeatedly detecting the water pressure output by the nozzle and the voltage output by the battery when the water flosser is working within a preset time, multiple water pressure detection signals and multiple voltage detection signals are obtained. By corresponding the obtained multiple water pressure detection signals and multiple voltage detection signals to multiple pressure values and multiple voltage values respectively, the relationship between the water pressure output by the water flosser and the voltage output by its battery within the preset time can be intuitively understood. Through this test method, users can accurately understand that the voltage output by the battery gradually decreases during continuous operation, which causes the water pressure output by the water flosser to gradually decrease. Users can also further adjust the water flosser based on the data obtained from the test, providing data support for subsequent adjustment work.
[0043] In this embodiment, a pressure detection unit for detecting the water pressure output by the water flosser and a voltage detection unit for detecting the output voltage of the battery of the water flosser are used to control the operation of the water flosser. The pressure detection signal when the water flosser is working and the voltage detection signal of the battery output voltage of the water flosser are obtained multiple times, thereby confirming the relationship between the water pressure output by the water flosser and the battery output voltage of the water flosser. The water flosser test system can further regulate the working power of the water flosser through the relationship between the water pressure output by the water flosser and the battery output voltage of the water flosser, thereby improving the accuracy of the water pressure output by the water flosser.
[0044] refer to Figure 2 In one embodiment of the present invention, the oral irrigator includes a battery, a motor, and a driving circuit for driving the motor. Before the step of controlling the oral irrigator to spray liquid to the pressure detection unit, the method further includes:
[0045] Step S400: responding to a mode trigger signal and confirming a target drive mode corresponding to the motor according to the mode trigger signal;
[0046] Step S500: According to the target driving mode corresponding to the motor, adjust the driving signal output to the driving circuit so that the working power of the motor is within the preset power range corresponding to the target driving mode, thereby making the output water pressure of the oral irrigator correspond to the target driving mode when working.
[0047] In this embodiment, at least one trigger button is provided on the surface of the water flosser body, and the user can simulate the triggering of the button through the water flosser test system to realize the opening of the water flosser and the switching of the mode. Among them, according to actual needs, the water flosser can be set with multiple driving modes, and the multiple driving modes of the water flosser can be switched one by one through multiple trigger buttons, or the continuous switching of the driving modes of the water flosser can be realized through the continuous triggering of a single trigger button. For example, the water flosser can have three driving modes, namely normal, gentle, and pulse, and different driving modes are intended to meet the diverse oral cleaning needs and sensitivity of users. Among them, the normal driving mode usually provides medium to high water pressure, which is suitable for most daily cleaning scenarios. It can effectively remove food residues and dental plaque on the surface of teeth and in the gaps between teeth, and is suitable for users who are accustomed to using the water flosser and have good oral health. The gentle driving mode is suitable for first-time users or people with sensitive gums and easy bleeding. The water pressure it provides is lower than the standard mode to reduce the stimulation of the gums and oral soft tissues, ensure that the cleaning is completed in a gentle way, and help users gradually adapt to the use of the water flosser. The pulse drive mode achieves cleaning through high-frequency water pulses, and these pulsed water flows can produce a powerful cleaning effect in a short period of time. Compared with continuous water flow, pulsed water flow can more effectively remove plaque and food debris without increasing the overall water pressure. It is especially suitable for cleaning periodontal pockets and areas around braces. Furthermore, the user can input a mode trigger signal by simulating the trigger button set on the surface of the water flosser through the water flosser test system, so that the water flosser confirms the target drive mode corresponding to the motor according to the mode trigger signal, so that the motor works according to the drive signal corresponding to the mode trigger signal.
[0048] It is understandable that in the process of using a battery to power the motor, the internal voltage of the battery gradually decreases due to continuous power supply, which in turn causes the power supply voltage of the motor to decrease. The reduction in the power supply voltage of the motor will cause the speed of the motor to decrease, which in turn causes the pump body driven by the motor to be unable to stably output the water in the water tank in the water flosser, so that the user cannot get a good user experience when using the water flosser. Therefore, in order to ensure that the speed of the motor is always in a relatively stable state, it is necessary to ensure that the working power of the motor is always in a relatively stable state, that is, to limit the working power of the motor to a preset power range. It should be understood that in the water flosser, a DC motor is usually used to drive the pump body to work, and the drive of the DC motor usually uses a PWM signal to adjust the average voltage of the motor power supply, thereby controlling the motor speed. By changing the pulse width, that is, the ratio of the high level duration to the total cycle (duty cycle), the motor speed can be finely adjusted without changing the power supply voltage. The power supply voltage of the battery is always in a state of continuous decrease due to the operation of the water flosser. If the pulse width of the PWM signal driving the DC voltage is not changed, the speed of the motor will be reduced. Among them, the output voltage of the battery is also the power supply voltage of the motor. Therefore, in order to ensure that the speed of the motor is in a relatively stable state, it is necessary to increase the ratio of the high-level duration to the total cycle, that is, to adjust the drive signal output to the drive circuit through the output voltage of the battery, so that the working power of the motor during operation is maintained within the preset power range corresponding to the target drive mode. The determination of the battery output voltage needs to be achieved through a voltage detection circuit. Furthermore, the speed of the motor is also related to the drive mode of the motor. For different drive modes, the speed of the motor is also different. For example, when the water flosser is in gentle mode, the speed of the motor is relatively slow; and when the water flosser is in pulse mode, the speed of the motor is relatively fast when it rotates. Therefore, it is also necessary to adjust the drive signal of the motor according to the drive mode of the motor.
[0049] In this embodiment, the drive signal controls the motor speed and the switch by controlling the working power of the motor. It is understandable that the drive signal will directly act on the drive circuit, and by controlling the drive circuit, the battery will be controlled to supply power to the motor. Furthermore, the drive circuit can be implemented by a plurality of switch circuits, and the switch circuit can be implemented by, for example, MOS tubes, IGBT tubes, thyristors, triodes, power tubes, etc. The water flosser controls the conduction or disconnection of the switch circuit by outputting a corresponding PWM signal through the control device, thereby changing the working power of the motor, and then changing the speed, starting or stopping the motor.
[0050] refer to Figure 3, further, the oral irrigator further includes a mode switching circuit and a power-on trigger circuit, wherein the mode switching circuit is used to output a mode switching signal when triggered, and the power-on trigger circuit is used to output a power-on signal when triggered; wherein the mode trigger signal includes a power-on signal and a mode switching signal; the oral irrigator is preset with a plurality of drive modes corresponding to the motor, and the plurality of drive modes are arranged in a first order; the steps of responding to the mode trigger signal and confirming the target drive mode corresponding to the motor according to the mode trigger signal are specifically as follows:
[0051] Step S410: in response to a power-on signal, confirming that the current driving mode is the target driving mode;
[0052] Step S420: In response to the mode switching signal, according to the first sequence, confirming the next driving mode after the current driving mode as the target driving mode.
[0053] In this embodiment, at least two types of trigger buttons are provided on the surface of the oral irrigator body, namely, a power-on trigger button and a mode switching button, and correspond to the power-on trigger circuit and the mode switching circuit respectively. It can be understood that the two types of trigger buttons provided on the surface of the oral irrigator body correspond to the power on / off function and the mode switching function of the oral irrigator respectively. Therefore, the mode trigger signal includes a working power-on signal and a mode switching signal. Among them, the power-on trigger button can realize the switching of the two modes of power on and off by repeated triggering of a single button. Multiple trigger buttons for the mode switching function can be set, and each trigger button corresponds to a driving mode; the trigger button of the mode switching function can also be set to a single one, and the sequential switching of the driving mode can be realized by multiple triggering of a single trigger button. Specifically, the working power-on signal can be obtained through the power-on trigger circuit, and the working power-on signal is input into the control device, so that the control device executes the driving mode last executed when the oral irrigator is turned off before, that is, the mode memory function. Among them, the driving mode last executed by the control device when the oral irrigator is turned off before is the first driving mode. When the mode switch button is not triggered, only the power-on trigger button is triggered, and the water flosser will drive the motor to work in the driving mode last executed when the water flosser was turned off. When the power-on trigger button is triggered, the mode switch button is triggered, and the control device will obtain the mode switch signal, and then switch the mode according to the first sequence, that is, switch from the first drive mode to the second drive mode, so that the motor works according to the second drive mode, and confirm the mode as the target drive mode. For example, the driving mode last executed when the water flosser was turned off was the pulse drive mode, that is, the pulse drive mode is the first drive mode; when the power-on trigger button is triggered, the mode switch button is triggered, and the control device switches the pulse drive mode to the normal drive mode according to the preset mode switching sequence, that is, the normal drive mode is the second drive mode. Among them, the mode switching circuit and the power-on trigger circuit can output corresponding control signals to the main control circuit in the water flosser through the control device to imitate the power-on signal and / or mode switching signal output to the main control circuit of the water flosser when the mode switching circuit and / or the power-on trigger circuit in the water flosser are triggered.
[0054] refer to Figure 4 In one embodiment of the present invention, the water flosser includes a battery and a motor. After the step of confirming the relationship between the output water pressure of the water flosser and the output voltage of the battery of the water flosser according to the multiple pressure detection signals and the multiple voltage detection signals, the method further includes:
[0055] A pressure detection signal of the water pressure output by the oral irrigator is obtained, and according to the pressure detection signal of the water pressure output, the working power of the motor is adjusted during operation so that the water pressure output by the oral irrigator is within a preset water pressure range.
[0056] In this embodiment, the water flosser testing system detects the voltage output by the water flosser when it is working through the voltage detection unit, and detects the water pressure output by the water flosser in different driving modes through the pressure detection unit. Within a preset time, a certain driving mode of the water flosser is fixed to work so that its output water pressure is within the preset water pressure range of the corresponding driving mode. From the above content, it can be seen that after the water flosser has been working continuously for a certain period of time, the water pressure output by the water flosser will decrease due to the decrease in the output voltage of the battery, and this reason is caused by the reduction in the working power of the motor in the water flosser. Therefore, in order to ensure that the output water pressure of the water flosser is within the preset water pressure range of the corresponding driving mode while the output voltage of the battery is reduced, the working power of the motor needs to be adjusted.
[0057] Furthermore, the oral irrigator further comprises a driving circuit for driving the motor to work, and the step of adjusting the working power of the motor during operation so that the water pressure output by the oral irrigator is within a preset water pressure range is specifically as follows:
[0058] Adjust the driving signal output to the driving circuit so that the working power of the motor is within the preset power range when working, thereby confirming that the water pressure output by the oral irrigator is within the preset water pressure range.
[0059] The pressure detection signal is obtained multiple times by the water flosser test system, so as to output a control signal to the main control circuit of the water flosser, so that the main control circuit in the water flosser changes the drive signal output to the drive circuit, thereby making the working power of the motor within the preset power range when working. Among them, the drive of the motor can be realized by PWM signal control, direct voltage change control, resistance control, current chopping control and the like. Taking the motor drive signal as a PWM signal as an example, the switching and control of the motor drive mode can be realized by changing the duty cycle and output frequency of the PWM signal. Among them, it is not difficult to understand that as the water flosser continues to work, the output voltage of the battery will gradually decrease, that is, the power supply voltage of the motor will gradually decrease. Increasing the duty cycle of the PWM signal means that within a PWM cycle, the proportion of high levels increases. Although the voltage of a single pulse is still the output voltage of the battery after the reduction, the effective average voltage through the motor will increase due to the longer high level time. In this way, the average input power of the motor can be increased without significantly increasing the instantaneous current, thereby maintaining the speed of the motor. Among them, the pressure value corresponding to the pressure detection signal is inversely proportional to the duty cycle of the PWM signal that drives the motor, that is, the greater the pressure value corresponding to the pressure detection signal, the smaller the duty cycle of the PWM signal that drives the motor; the smaller the pressure value corresponding to the pressure detection signal, the greater the duty cycle of the PWM signal that drives the motor. It can be understood that the water flosser test system can test the relationship between the battery output voltage, the nozzle output water pressure and the duty cycle of the PWM signal by obtaining the voltage detection signal and the pressure detection signal of the water flosser under different driving modes within a preset time, and by continuously adjusting the duty cycle of the PWM signal output to the motor.
[0060] The present invention also proposes a test control device, the test control device comprising: a memory, a processor, and a test control program stored in the memory and executable on the processor, the test control program being configured to implement the steps of the test method for the water flosser as described in any one of the above. It is worth noting that since the test control device of the present invention is based on the test method for the water flosser described above, the embodiments of the test control device of the present invention include all the technical solutions of all the embodiments of the test method for the water flosser described above, and the technical effects achieved are also exactly the same, which will not be repeated here.
[0061] The present invention also proposes a water flosser test system, which includes a pressure detection unit, a voltage detection unit and the test control device as described above. It is worth noting that since the water flosser test system of the present invention is based on the test control device described above, the embodiments of the water flosser test system of the present invention include all technical solutions of all embodiments of the test control device described above, and the technical effects achieved are also exactly the same, which will not be repeated here.
[0062] refer to Figure 4 In one embodiment of the present invention, the output end of the pressure detection unit is electrically connected to the test control device and is used to output a pressure detection signal; the first end of the voltage detection unit is connected to the water flosser battery, and the second end of the voltage detection unit is electrically connected to the test control device and is used to output a voltage detection signal of the water flosser battery;
[0063] Wherein, the test control device is used to adjust the output water pressure of the water flosser according to the pressure detection signal and the voltage detection signal.
[0064] In this embodiment, the pressure detection unit can be implemented by a strain gauge pressure sensor, a ceramic pressure sensor, a capacitive pressure sensor, etc. By receiving the pressure applied to the force-bearing surface and outputting a pressure detection signal, the test control device in the water flosser test system can confirm the water pressure output by the water flosser at this time. The voltage detection unit can be implemented by a voltage divider circuit, a differential amplifier circuit, a comparator circuit, etc. Among them, the voltage divider circuit divides the voltage by connecting two or more resistors in series, and proportionally reduces the voltage to be measured to an input range suitable for a measuring instrument (such as an ADC). For example, two resistors are connected in series, and the measuring point is located between the two resistors. The voltage drop calculated by Ohm's law is a part of the voltage to be measured. The differential amplifier circuit is suitable for accurately measuring the potential difference between two points in the circuit, especially when there is common-mode voltage interference, the differential amplifier circuit is very useful. The differential amplifier has two input terminals, which are connected to the positive and negative terminals of the voltage to be measured, respectively, and can effectively suppress common-mode noise, amplify differential-mode signals, and improve measurement accuracy. By adopting the voltage detection unit, the output voltage of the battery can be effectively detected, so that the test control device can control the main control circuit of the water flosser to output an accurate driving signal to the driving circuit, thereby effectively controlling the output water pressure of the water flosser.
