Description

Technical Field

[0001] This invention relates to the field of oral medical technology, specifically to an ultrasonic air-blasting teeth cleaning system with an electric external water connection. Background Technology

[0002] Currently, dental scaling equipment typically uses external water systems or water supply systems with built-in water bottles. The ultrasonic tip and the abrasive nozzle generate heat during operation as they rub against the tooth surface or tartar. A continuous flow of water is needed to cool the tooth surface and ensure the treatment is conducted at a safe temperature; this water flow is fundamental to painless treatment. In a scaling system, the continuous water flow washes away tartar fragments, plaque, and blood that have been broken up or loosened by the ultrasonic waves, maintaining a clear view. In an abrasive system, water acts as a carrier and binder for the powder, and a uniform water flow reduces fly-through.

[0003] The external water inlet pressure is 0.1 MPa-0.5 MPa. Usually, a mechanical water regulating valve is needed to reduce the water flow. When the water flow is adjusted by manually turning the water regulating valve, the flow rate cannot be set directly. The flow rate can only be judged by observing the water output after adjustment. Repeated adjustments are needed to achieve the ideal water output, which is cumbersome, affects efficiency, and delays treatment. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic air-jet cleaning system with an electric external water connection, aiming to solve the technical problem that existing oral cleaning equipment can only be manually adjusted repeatedly when adjusting the external water connection, which leads to delays in treatment.

[0005] To achieve the above objectives, the present invention provides an ultrasonic air-blasting dental cleaning system with an electric external water connection, comprising a water regulating device and a dental cleaning application module. The water regulating device includes a motor assembly, a water inlet, a housing, a solenoid valve, a main board, a touch screen, and a tail cable interface. The motor assembly, the solenoid valve, and the main board are all disposed within the housing, while the touch screen is disposed outside the housing and electrically connected to the motor assembly, the solenoid valve, and the main board. The water inlet and the tail cable interface are respectively disposed at opposite ends of the housing. The input port of the water inlet is connected to an external water source, and the output port of the tail cable interface is connected to the dental cleaning application module.

[0006] The motor assembly includes a motor, a drive line, an inlet connector, and an outlet connector. The motor is connected to the main board via the drive line. The main board drives the motor to rotate and controls the motor stroke to electrically adjust the amount of external water. The inlet connector is connected to the output port of the inlet interface, and the outlet connector is connected to the solenoid valve. The water path of the solenoid valve is connected to the input port of the tail wire interface.

[0007] The motor assembly is equipped with an optical coupler position sensor to detect and record the start and stop positions of the motor rotation.

[0008] The touch screen is equipped with settings for working mode, water volume level, and power level. The ultrasonic sandblasting system with electric external water connection calculates the adjustment increment based on the working mode and water volume level, determines the baseline flow rate based on the power level, and then obtains the target flow rate by combining the adjustment increment.

[0009] In the water regulating device, starting from the minimum flow rate, each level increases by a fixed flow rate.

[0010] The target flow rate is linearly related to the target pulse number of the motor, and the instruction controls and adjusts the motor's stroke through the drive circuit of the motherboard.

[0011] The external water flow rate range of the water regulating device is 0-150ml / min, and the default water flow rate setting is higher than the power setting.

[0012] This invention provides an electrically powered ultrasonic air-blasting dental cleaning system with external water supply, including a water regulating device and a dental cleaning application module. The water regulating device consists of a motor assembly, a water inlet interface, a housing, a solenoid valve, a main board, a touch screen, and a tail cable interface. The touch screen allows selection of the water supply mode and level. The main board controls the motor stroke based on the working mode, power level, and water volume level, combined with a linear flow distribution algorithm. Furthermore, closed-loop calibration using an optocoupler position sensor ensures stable flow and prevents the motor from deviating from its starting and stopping positions during rotation. This achieves electrically powered and precise regulation of the external water flow, improving the water volume control accuracy and ease of operation of dental equipment.

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] This invention provides an electrically powered, externally connected ultrasonic air-blasting dental cleaning system, including a water regulating device and a dental cleaning application module. Please refer to [link / reference]. Figure 1 The water regulating device includes a motor assembly 1, a water inlet 2, a housing 3, a solenoid valve 4, a main board 5, a touch screen 6, and a tail cable interface 7. The motor assembly 1, the solenoid valve 4, and the main board 5 are all located inside the housing 3. The touch screen 6 is located outside the housing 3 and is electrically connected to the motor assembly 1, the solenoid valve 4, and the main board 5. The water inlet 2 and the tail cable interface 7 are located at opposite ends of the housing 3. The inlet of the water inlet 2 is connected to an external water source, and the outlet of the tail cable interface 7 is connected to the teeth cleaning application module.

[0021] like Figure 2 As shown, the motor assembly 1 includes a motor 11, a drive line 12, a water inlet connector 13, and a water outlet connector 14. The motor 11 is connected to the main board 5 via the drive line 12. The main board 5 drives the motor 11 to rotate and controls the stroke of the motor 11 to electrically adjust the amount of external water. The water inlet connector 13 is connected to the output port of the water inlet interface 2, and the water outlet connector 14 is connected to the solenoid valve 4. The water path of the solenoid valve 4 is connected to the input port of the tail wire interface 7.

[0022] In this embodiment, the motor 11 is connected to the main board 5 via the drive line 12. The main board drives the motor 11 to rotate and controls the stroke of the motor 11 to electrically adjust the amount of external water.

[0023] The motherboard 5 and touchscreen 6 interact via a communication protocol. The touchscreen 6 allows selection of two water supply methods: external water supply and water bottle. When external water supply is selected, the touchscreen 6 sends the user-selected water volume level to the motherboard 5. The motherboard 5 parses the data, and the motor drive circuit outputs the corresponding stroke according to the different levels. The stroke and water output are linearly related, enabling electric adjustment of the external water supply. Simultaneously, the motherboard 5 presets the water output based on the working mode and power level. The power level value and the preset water output value are directly proportional. During operation, friction occurs on the tooth surface; the preset water output value cools the tooth surface, ensuring the treatment process is conducted at a safe temperature. The instrument's water output is the sum of the water volume level value and the preset power / water volume value. This operating mode is only available with the electric external water supply function.

[0024] The water inlet 2 is connected to a water source outside the housing 3 and to the water inlet 13 of the motor assembly 1 inside the housing 3. The water outlet 14 of the motor assembly 1 is connected to the solenoid valve 4. The water path of the solenoid valve 4 is connected to the tail wire interface 7 and the line is connected to the main board 5 to control the opening and closing of the water path of the electric external water supply.

[0025] The adjustable external water flow rate of the motor assembly 1 is 0-150ml / min. The motherboard 5 receives the water volume and power settings from the touch screen 6 and intelligently sets the flow rate. When the device is first turned on, the default water volume setting of the touch screen 6 is higher than the power setting to ensure sufficient water output for the cooling instrument application, reduce the risk of patients being scalded by high temperatures, and improve patient satisfaction. The motor assembly 1 has a position sensor inside, and the motherboard 5 monitors the position of the motor 11 in real time to prevent the motor 11 from deviating from its starting and stopping positions during rotation, thereby achieving precise control of the external water flow rate.

[0026] The overall workflow of this invention is as follows: Figure 3 As shown, after user input and connection to an external water source, the water flows to the teeth-cleaning application module after flow regulation. Furthermore, during flow regulation, this invention uses an algorithm to precisely control the flow rate at each level. The algorithm first determines the flow range based on the working mode, then determines a baseline flow rate (initial value) based on the power level. Next, based on the selected water level, it calculates the adjustment increment: Adjustment increment = (flow range / total number of water levels) × current water level. A proportional adjustment is then made based on the baseline flow rate to obtain the final target flow rate: Target flow rate = Baseline flow rate + Adjustment increment. Finally, the target flow rate is converted into the target position (number of pulses) of the stepper motor to control the specific water volume. The algorithm flowchart is shown below. Figure 4 The adjustment steps are described below with reference to specific embodiments:

[0027] Step S1: Select the core operating mode and water supply method. On the touchscreen 6: Select the core operating mode (such as G, P, or E mode). Select "External Water" as the water supply method. Set the power level (such as high, medium, low) and water volume level (level n, out of N levels) required for the current operation.

[0028] Step S2: Determine the power-related flow baseline and range. After receiving the instruction, the motherboard 5 retrieves two sets of key parameters from the internal parameter table based on the operating mode and power level: Base flow value Q_base: The recommended center flow rate for this combination. Fine-tuning flow range ΔQ: The absolute flow range that can be adjusted at this power level, with upper and lower limits of [Q_min, Q_max], and ΔQ = Q_max - Q_min.

[0029] Step S3: Calculate the flow rate increment per unit speed setting. Mainboard 5 calculates the absolute flow rate increment corresponding to each water speed setting: ΔQ_per_step = ΔQ / N

[0030] Step S4: Calculate the target flow rate. Calculate the target absolute flow rate corresponding to the current water level: Q_target = Q_min + (n × ΔQ_per_step). Equivalent formula transformation: This formula can be expanded to Q_target = Q_min + n ×(ΔQ / N), which essentially means "starting from the minimum flow rate, each level adds a fixed flow rate", achieving a strictly linear allocation.

[0031] Step S5: Target command conversion. The motherboard 5 converts the calculated absolute target flow rate Q_target into the target pulse number of the stepper motor 11 according to the "flow-position" conversion model.

[0032] Step S6: Drive execution and closed-loop calibration. After the external switch signal is triggered, the motherboard 5 drives the stepper motor 11 to rotate to the target position and uses an optocoupler sensor to perform real-time position closed-loop calibration.

[0033] Step S7: Coordinated water supply output. After the motor is in position, the main board 5 opens the solenoid valve 4, and the precisely regulated water flow is output to the application section through the tail wire.

[0034] In summary, the present invention has the following beneficial effects:

[0035] It enables electric adjustment of external water supply, supplying water according to the water volume setting on the user's screen, thus solving the problem in existing dental treatments where the flow rate can only be adjusted manually by repeatedly adjusting the knob, which can delay treatment.

[0036] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
