It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0055] Sonic wave irrigating equipment is the most common oral medical device. The principle of the sonic wave irrigating equipment is to use sound waves to produce mechanical vibrations on the liquid in the root canal, accelerate the breaking of the air resistance of the root canal at the apex, and allow the flushing liquid to enter the apex smoothly. Sound waves are different from ultrasonic waves. The operating frequency of ultrasonic equipment is 25Hz~40kHz. The operating frequency of sonic wave irrigating equipment is lower, the amplitude is larger, and the shear stress generated is small. Therefore, the sonic wave irrigating equipment is an indispensable medical device for oral doctors to carry out root canal treatment.

[0056] Existing ultrasonic washing equipment usually has only one operating frequency, which cannot meet the needs of different treatment situations.

[0057] Based on the acoustic wave washing device mentioned in the above background technology, an embodiment of the present application provides a mode switching method of the acoustic wave washing device.

[0058] See also Figure 1 As shown, the embodiment of the present application provides a mode switching method of an acoustic washing device, comprising the following steps:

[0059] The sonic washing device is in standby mode.

[0060] Step S100, the switching button circuit outputs a first closed signal to the control unit, and the maintenance time of the first closed signal is a first set time, the control unit outputs a feedback signal to the drive circuit, adjusts the voltage value output by the drive circuit, and the sonic washing device switches to the next working mode.

[0061] In step S200, the switch button circuit outputs a second closed signal to the control unit while the switching button circuit outputs a first closed signal to the control unit, wherein the first closed signal and the second closed signal simultaneously maintain a second set time, and the control unit outputs a full load signal to the drive circuit to adjust the drive circuit to output a maximum voltage value, and the sonic washing device switches to overclocking mode.

[0062] In this embodiment, the second set time is greater than the first set time;

[0063] The first set time ranges from 100ms to 2000ms. Specifically, the first set time can be set to any one of 100ms, 200ms, 500ms, 1000ms, 1500ms, and 2000ms, or a range formed between any two values;

[0064] The range of the second set time is 2000ms to 4000ms. Specifically, the first set time can be set to any one of 2000ms, 2500ms, 3000ms, 3500ms, and 4000ms, or a range formed between any two values;

[0065] In this embodiment, in order to avoid an error between the first set time and the second set time, the time difference between the first set time and the second set time is at least 500 ms.

[0066] The embodiment of the present application provides a mode switching method for an ultrasonic cleaning device. By setting the switching of multiple working modes, it is convenient to meet the multi-functional needs of users and improve the user experience. At the same time, through the setting of the overclocking mode, the amplitude of the ultrasonic cleaning device can be greatly improved according to the actual needs of users, thereby improving the effect of root canal cleaning to meet the needs of users.

[0067] In this embodiment, when the acoustic wave washing device is in standby state, the step S100 is specifically as follows: the acoustic wave washing device maintains a power-on state, and the control unit monitors the second switch S2 every 10 ms. When the second switch S2 is pressed, the RC pin of the control unit is set low, and the control unit starts timing. When the second switch S2 is released, the RC pin of the control unit is pulled high, and the control unit ends timing. When the control unit's timing of the second switch S2 is within the range of the first set time, the control unit receives a first closed signal and forms a feedback signal to output to the drive circuit to adjust the voltage value output by the drive circuit, and the acoustic wave washing device switches to the next working mode.

[0068] In this embodiment, as the working modes are switched downward one by one, the output voltage value of the driving circuit gradually increases. After the working mode is selected, it switches to the initial working mode for circulation. The working mode of the ultrasonic washing device is set to a five-speed working mode to correspond to the five working amplitudes of the ultrasonic washing device. After the working mode is selected, it switches to the initial working mode for circulation.

[0069] In this embodiment, when the sonic cleaning device is in a standby state, the step S200 is specifically as follows: the sonic cleaning device maintains a power-on state, and the control unit monitors the first switch S1 and the second switch S2 every 10 ms; when the first switch S1 is pressed, the RB5 pin of the control unit is set low, and the control unit starts timing; when the first switch S1 is released, the RB5 pin of the control unit is pulled high, and the control unit ends timing the first switch S1; when the second switch S2 is pressed, the RC pin of the control unit is set low, and the control unit starts timing; when the second switch S2 is released, the RC pin of the control unit is pulled high, and the control unit ends timing the second switch S2; when the control unit detects that the first switch S1 and the second switch S2 are pressed at the same time, and when the timing of the first switch S1 and the second switch S2 by the control unit are both within the range of the second set time, the control unit receives the first closed signal output from the switching button circuit and the second closed signal output from the switch button circuit and outputs a full load signal to the drive circuit to adjust the maximum voltage value output by the drive circuit, and the sonic cleaning device switches to the overclocking mode.

[0070] The mode switching method of the sonic washing device provided in the embodiment of the present application monitors the second switch to form a second closed signal, and then forms a feedback signal to output to the driving circuit to adjust the output voltage value, so as to realize switching of the working mode of the sonic washing device in the case of a single switch, and the control method is simple; at the same time, further through the coordination of the switch button circuit and the switching button circuit, the control unit monitors the first switch and the second switch to form and receive the first closed signal and the second closed signal, and then forms a feedback signal to output to the driving circuit to adjust the output voltage value, so as to realize the coordination of the first switch and the second switch, thereby setting an overclocking mode in the original working mode additionally, and the control method is simple, which meets the user's overclocking needs and improves the user experience.

[0071] In some embodiments, after the user switches the acoustic wave washing device to the next working mode through the above step S100 or switches the acoustic wave washing device to the overclocking mode through the above step S200, after completing the working mode selection, it is necessary to start the acoustic wave washing device to put the acoustic wave washing device into working state, which is achieved by the following steps:

[0072] The switch button circuit outputs a second closed signal to the control unit, and the maintenance time of the second closed signal is a first set time. The control unit converts the second closed signal into a switch signal and outputs it to the drive circuit to control the drive circuit to be turned on, and the ultrasonic washing device enters a working state.

[0073] In this embodiment, when the first switch S1 is pressed, the RB5 pin of the control unit is set low, and the control unit starts timing; when the first switch S1 is released, the RB5 pin of the control unit is pulled high, and the timing of the first switch S1 by the control unit ends; when the timing of the first switch S1 by the control unit is within the range of the first set time, the control unit receives the second closed signal and converts it into a switch signal and outputs it to the drive circuit, controls the start-up of the drive circuit, and the ultrasonic washing device enters a working state.

[0074] In some embodiments, before the acoustic wave washing device enters the working state, the working angle of the working tip needs to be adjusted to adapt to different operating requirements, wherein the method for adjusting the working angle of the working tip includes the following steps:

[0075] The switch button circuit continuously outputs a first closed signal to the control unit, and the control unit converts the first closed signal into a switch signal and outputs it to the drive circuit, thereby controlling the drive circuit to be turned on, driving the motor to rotate forward, and driving the working tip to rotate.

[0076] In this embodiment, when the second switch S2 is pressed, the RC pin of the control unit is set low, and the control unit starts timing. When the control unit monitors that the second switch S2 continues to remain closed, the control unit receives the first closing signal and forms a switch signal to output to the drive circuit, controls the start-up of the drive circuit, drives the motor to rotate forward, and drives the working tip to rotate.

[0077] When the working angle adjustment of the working tip is completed, the control switch button circuit stops outputting the first closing signal to the control unit, and the control unit outputs a switch signal to the drive circuit, controls the drive circuit to disconnect, drives the motor to stop, and stops the working tip from rotating.

[0078] In this embodiment, the user can adjust the rotation direction of the working tip of the acoustic wave washing device according to actual needs, which is specifically achieved through the following steps:

[0079] While the switching button circuit continuously outputs a first closed signal to the control unit, the switch button circuit outputs a second closed signal to the control unit, and the maintenance time of the second closed signal is a first set time. The control unit outputs a feedback signal to the drive circuit to adjust the voltage value output by the drive circuit and control the drive motor to adjust the rotation direction to reverse the rotation direction of the working tip.

[0080] In this embodiment, when the initial rotation direction of the drive motor is forward, after the above steps are performed, the rotation direction of the drive motor is adjusted to reverse; further, by performing the above steps again, the rotation direction of the drive motor can be further adjusted to forward.

[0081] The embodiment of the present application realizes multi-mode adjustment of the sonic washing device through a combination of different first closed signals and second closed signals, improves the multi-functional adjustment capability of the sonic washing device, meets the multi-functional needs of users, and improves the user experience.

[0082] In some embodiments, before the acoustic wave washing device is in the standby mode, it is necessary to start the acoustic wave washing device, which is specifically achieved by the following steps:

[0083] The mode switching method further comprises the following steps:

[0084] The sonic washing device is in a shutdown state;

[0085] The switch button circuit outputs a second closed signal to the control unit. Based on the second closed signal, the control unit controls the power supply module to be connected to the main control module and the switch button circuit respectively, and the sonic washing device enters a standby state.

[0086] In this embodiment, the holding time of the second closing signal can be set to be greater than or equal to the first set time and less than the second set time.

[0087] In other embodiments, the holding time of the second closing signal may also be set to be greater than the second set time.

[0088] In this embodiment, the sonic cleaning device is in the off state, and the switch button is pressed, the first switch S1 of the switch button circuit is closed, the second diode D2 is turned on, and the current of the power supply flows to the gate of the field effect transistor Q1, the gate voltage of the field effect transistor Q1 is pulled low, Vgs is less than 0, the field effect transistor Q1 is turned on, and the sonic cleaning device is started; at this time, the RA6 pin of the control unit is set high, so that the transistor Q2 is turned on, so when the first switch S1 is disconnected, the gate of the field effect transistor Q1 is still maintained in a low state, so that the field effect transistor Q1 remains in a turned-on state, and the sonic cleaning device maintains a standby state or a working state.

[0089] In some embodiments, when the user has finished using the device and needs to shut down the sonic washing device, this can be achieved by:

[0090] The mode switching method further comprises the following steps:

[0091] The switch button circuit outputs a second closed signal to the control unit, and the maintenance time of the second closed signal is a second set time. The control unit controls the power supply module to be disconnected from the main control module and the switch button circuit respectively based on the second closed signal, and the ultrasonic washing device enters a shutdown state.

[0092] In this embodiment, the control unit monitors the first switch S1 every 10 ms. When the first switch S1 is pressed, the RB5 pin of the control unit is set low, and the control unit starts timing. When the first switch S1 is released, the RB5 pin of the control unit is pulled high, and the control unit ends timing. When the control unit's timing of the first switch S1 is within the range of the second set time, the control unit receives the second closed signal to control the power supply module to disconnect from the main control module and the switch button circuit respectively, and the ultrasonic washing device enters a shutdown state.
