In order to solve the technical problem of unstable output water pressure in the output control technology of the traditional tooth flushing device, in the embodiment, an output control method of the tooth flushing device is particularly provided, which is used for controlling the output water pressure of the tooth flushing device to be in a stable range. The tooth flushing device comprises a power module, a motor and a driving module, wherein one end of the motor is electrically connected with the power module, and the other end of the motor is electrically connected with the driving module. Optionally, the motor may be a motor, and the motor is driven by the power module and the driving module to drive the piston to reciprocate in the pump body through the gear, so that the volume in the pump body changes, water pressure is generated in the pump body, and a high-speed water column is ejected from a nozzle of the tooth irrigator. Fig. 1 is a flowchart of an output control method of the dental irrigator in an embodiment, and the output control method in the embodiment is described by taking the dental irrigator as an example. As shown in fig. 3, the output control method of the tooth irrigator comprises steps 102 to 108:
step 102: and sending a pulse width modulation signal to the driving module to control the rotation speed of the motor.
Pulse Width Modulation (PWM) is a technology for controlling an analog circuit by using digital output of a microprocessor, a motor may be a dc motor, and this embodiment changes a voltage amplitude value transmitted to the motor by adjusting a driving voltage Pulse Width and matching with some corresponding energy storage elements in the circuit, thereby changing a rotation speed of the dc motor.
In a specific embodiment, as shown in fig. 4, a schematic circuit diagram of an output control system of the tooth irrigator in one embodiment is provided, the output control system comprising: the signal input end P05, NMOS pipe U16, motor B1 and battery positive pole VM +, one end of motor B1 is connected with battery positive pole VM +, the other end of motor B1 is connected with the drain electrode of NMOS pipe U16, the source electrode of NMOS pipe U16 is grounded, and the grid electrode of NMOS pipe U16 is connected with signal input end P05. The step of sending a pulse width modulation signal to the driving module to control the rotation speed of the motor further includes steps 1201 to 1203 shown in fig. 2:
step 1201: when a high voltage is input to the grid electrode of the NMOS tube, the NMOS tube is conducted.
Specifically, the mos transistor is a metal-oxide-semiconductor (semiconductor) field effect transistor, and the field effect transistor controls a drain current by using a gate voltage, and has the characteristics of simple driving circuit, low driving power, high switching speed and high operating frequency. When the input PWM signal is high, the grid electrode receives high voltage, and the NMOS tube is conducted. Optionally, a PMOS transistor may be further selected to perform turn-off control on the motor, and similarly, according to the characteristics of the PMOS transistor, when the input PWM signal is "low", the PMOS transistor is turned on.
Step 1202: and controlling the conduction duration of the NMOS tube according to the duty ratio of the pulse width modulation signal, wherein the average voltage at two ends of the motor is related to the conduction duration.
The duty ratio refers to the time ratio of the high level and the low level of the square wave in the pulse width modulation signal, for example, a 20% duty cycle waveform has a high level time of 20% and a low level time of 80%, while a 60% duty cycle waveform has a high level time of 60% and a low level time of 40%, and the higher the duty cycle is, the longer the high level time is, the higher the output pulse amplitude is, i.e., the higher the voltage is. If the duty ratio is 0%, then the high level time is 0, then no voltage is output; if the duty ratio is 100%, the full voltage is output.
Furthermore, the power module comprises a battery, one end of the motor is connected with the positive electrode of the battery, the other end of the motor is connected with the drain electrode of the NMOS tube, and the source electrode of the NMOS tube is grounded; when the NMOS tube is conducted, a voltage difference is formed between two ends of the motor to generate a rotation torque.
Step 1203: and determining the output power of the motor according to the average voltage at two ends of the motor.
The purpose of adjusting the output voltage can be realized by adjusting the duty ratio of the pulse width modulation signal, and further the adjustment of the output power of the motor is realized.
Therefore, the larger the duty ratio of the PWM signal, that is, the larger the pulse width, the larger the average voltage supplied to the motor, and the higher the motor output power. Conversely, the smaller the duty ratio, the smaller the pulse width, the smaller the average voltage supplied to the motor, and the lower the motor output power.
The output control method provided by the embodiment adjusts the output power of the motor by adjusting the duty ratio of the PWM signal, realizes that the analog signal is controlled in a digital manner, and can greatly reduce the cost and power consumption.
Step 104: and acquiring a target voltage value under the current gear, and acquiring an input voltage value of the power module according to a preset time interval.
Wherein, the tooth flushing device is provided with a plurality of gears, and each gear is correspondingly provided with different target voltage values. For example, the tooth flushing device is provided with an opening gear and a closing gear, when a user shifts the switch to the opening gear, the tooth flushing device is started to work, and when the user shifts the switch to the closing gear, the tooth flushing device stops working; the starting gear further comprises three gears which respectively represent a low gear, a medium gear and a high gear, and when the current gear is determined to be the first gear, the obtained target voltage value is 1.8V; when the current gear is determined to be the second gear, the obtained target voltage value is 2.4V; and when the current gear is determined to be the third gear, the obtained target voltage value is 3V. In the embodiment, the target voltage value in the current gear is determined by acquiring the current gear.
Further, when the dental irrigator is in a power-on state, the input voltage value of the power module is obtained according to a preset time interval, for example, the input voltage value of the power module can be detected every 2 seconds, and the duty ratio of the pulse width modulation signal is updated according to the input voltage value. It is understood that other time intervals may be set, and this embodiment is not limited thereto.
Step 106: and adjusting the duty ratio of the pulse width modulation signal according to the ratio of the target voltage value to the input voltage value.
Specifically, after a target voltage value under the current gear and an input voltage value of the power module are obtained, the target voltage value and the input voltage value are calculated according to a formula
DUTY=VT/VBAT
Calculating the duty ratio of the pulse width modulation signal; wherein DUTY is DUTY ratio, VT is target voltage value, and VBAT is input voltage value.
Step 108: and controlling the terminal voltage value of the motor according to the adjusted pulse width modulation signal.
The specific adjustment process is shown in fig. 5, which is a graph of the duty ratio varying with the battery level in one embodiment, wherein the horizontal axis of fig. 5 represents the battery level percentage, and the vertical axis represents the duty ratio of the PWM signal. For example, when the battery is selected as the power input, the battery output voltage is 4.15V when the battery power is 100%, 4.065V when the battery power is 90%, 3.98V when the battery power is 80%, and so on, and 3.385V when the battery power is 10%.
As can be seen from fig. 5, when the input voltage value of the power supply module decreases, the present embodiment can adjust the duty ratio of the pwm signal to increase the duty ratio of the pwm signal, so that the output control system of the dental scaler is more linear and the robustness of the system is enhanced.
