The following are detailed descriptions.

[0097] Example 1

[0098] See also Figure 1 , Figure 1 This is a flow chart of an air heating control method for a sandblasting and tooth cleaning device disclosed in an embodiment of the present invention. Figure 1 The air heating control method of the sandblasting tooth cleaning equipment described can be applied to the air heating control device of the sandblasting tooth cleaning equipment, and the device may include one of an intelligent device, an intelligent terminal, an intelligent system and a server, wherein the server may be a local server or a cloud server, which is not limited in the embodiment of the present invention; further, a single-chip microcomputer may be provided in the device, exemplarily, the single-chip microcomputer may be a PIC single-chip microcomputer (Peripheral Interface Controller), which is not limited in the embodiment of the present invention; further, the device can be applied to the sandblasting tooth cleaning equipment, wherein the sandblasting tooth cleaning equipment is equipped with a heating function, and the heating function may include an air heating function, and optionally, the heating function may also include at least one of a water flow heating function, a sand powder heating function and a sand-water mixture heating function, which is not limited in the embodiment of the present invention. As Figure 1 As shown, the air heating control method of the sandblasting and cleaning equipment may include the following operations:

[0099] 101. After detecting a heating instruction, generate a heating control signal corresponding to the heating instruction.

[0100] In the embodiment of the present invention, the heating control signal matches the air heating function of the sandblasting and cleaning equipment.

[0101] 102. Input the heating control signal to the air heating circuit corresponding to the sandblasting and cleaning equipment.

[0102] In the embodiment of the present invention, optionally, the heating control signal may be a PWM (Pulse Width Modulation) signal, or may be other types of control signals, which is not limited in the embodiment of the present invention.

[0103] 103. According to the heating control signal, control the heating control unit of the air heating circuit to perform a temperature adjustment operation, so that the temperature of the airflow flowing through the heating control unit is adjusted to the target temperature corresponding to the heating instruction.

[0104] In the embodiment of the present invention, the temperature adjustment operation may be to adjust the temperature of the heat-generating component in the heat-generating control unit, thereby adjusting the temperature of the airflow passing through the heat-generating component.

[0105] In an embodiment of the present invention, the airflow is used to spray the sand powder stored in the sandblasting and tooth cleaning equipment; further, the airflow can be used to spray the stored sand powder when the sandblasting and tooth cleaning equipment is in a working state; further optionally, the sand powder can be stored in a powder tank of the sandblasting and tooth cleaning equipment, which is not limited in the embodiment of the present invention.

[0106] It can be seen that the method described in the embodiment of the present invention can generate a heating control signal corresponding to the heating instruction after detecting the heating instruction, and input the heating control signal into the air heating circuit to control the heating control unit in the circuit to perform a temperature adjustment operation, so that the temperature of the air flow flowing through the heating control unit is adjusted to the target temperature corresponding to the heating instruction to achieve the effect of air heating. In this way, by adding an air heating function to the sandblasting and tooth cleaning equipment, the air flow required for sandblasting by the sandblasting and tooth cleaning equipment is heated, which can improve the control accuracy of air heating while improving the heating flexibility, heating efficiency and heating accuracy of the mixture of sand powder and water used in the sandblasting and tooth cleaning equipment, thereby reducing the possibility of the patient feeling uncomfortable when the sand-water mixture acts on the user's teeth, and further improving the user's experience of using the sandblasting and tooth cleaning equipment.

[0107] In an optional embodiment, the heating instruction may include a first heating instruction or a second heating instruction, which is not limited in this embodiment of the present invention.

[0108] Optionally, the heating instruction can be determined by:

[0109] Obtaining a first heating instruction triggered by a user for the sandblasting and tooth cleaning device; the first heating instruction includes a heating temperature instruction and / or a heating gear instruction;

[0110] or,

[0111] Determine the user's usage preference information for sandblasting and tooth cleaning equipment;

[0112] Detecting the real-time distance parameters between the nozzle of the sandblasting and tooth cleaning equipment and the user, as well as the ambient temperature parameters corresponding to the environment in which the sandblasting and tooth cleaning equipment is located;

[0113] A second heating instruction is generated according to the usage preference information, the real-time distance parameter, and the ambient temperature parameter.

[0114] Optionally, the first heating instruction may be an instruction for the heating function of the sandblasting and cleaning device, or may be an instruction only for the air heating function, which is not limited in the embodiment of the present invention.

[0115] Among them, the heating temperature instruction can be an instruction to instruct the air heating circuit to heat the target heating object to the target temperature. For example, the target temperature can be 35°C, or it can be other temperature values, which is not limited by the embodiment of the present invention; the heating gear instruction can be an instruction to instruct the air heating circuit to heat the target heating object to the temperature corresponding to the target gear, wherein the target gear can be one of the temperature gears preset by the sandblasting and cleaning equipment, which is not limited by the embodiment of the present invention; wherein the target heating object includes at least the above-mentioned airflow, and optionally, the target heating object can also include sand powder and / or water flow, which is not limited by the embodiment of the present invention.

[0116] Optionally, the method of determining the user's usage preference information for the sandblasting tooth cleaning device may be specifically as follows:

[0117] Obtaining the user's basic information and / or the user's usage records of sandblasting and tooth cleaning equipment;

[0118] Determine the user's usage preference information for the sandblasting tooth cleaning device based on the user's basic information and / or usage records.

[0119] Among them, optionally, the user basic information may include the user's age and / or dental diagnosis information, which is not limited in the embodiment of the present invention; the usage record may include at least one of historical usage parameters, historical control instructions, and usage experience feedback information, which is not limited in the embodiment of the present invention.

[0120] In this way, by analyzing the user's usage preference for the sandblasting tooth cleaning device through the user's basic information and / or usage records, the flexibility and accuracy of determining the usage preference information can be improved, thereby facilitating the improvement of the accuracy of generating the heating instruction.

[0121] Wherein, illustratively, the real-time distance parameter between the nozzle of the sandblasting and cleaning device and the user may specifically be the real-time distance between the nozzle and the user's teeth, which is not limited in the embodiment of the present invention.

[0122] Optionally, a second heating instruction is generated based on usage preference information, real-time distance parameters and ambient temperature parameters. Specifically, the user's preferred teeth cleaning temperature under current conditions is determined based on usage preference information, real-time distance parameters and ambient temperature parameters, and a second heating instruction for the preferred teeth cleaning temperature is generated.

[0123] It can be seen that this optional embodiment can generate a second heating instruction by directly obtaining the first heating instruction triggered by the user for the sandblasting tooth cleaning device, or by combining the user's usage preference information for the sandblasting tooth cleaning device and the real-time distance parameters between the nozzle of the sandblasting tooth cleaning device and the user, and the ambient temperature parameters corresponding to the environment in which the sandblasting tooth cleaning device is located. The heating instruction can be obtained or generated by multiple methods, which can improve the flexibility and efficiency of determining the heating instruction. At the same time, by combining factors such as user preferences and real-time ambient temperature, the generated heating instruction can be more matched with the user's temperature preferences and environmental conditions, which can be conducive to generating more personalized heating instructions, thereby facilitating improving the accuracy of heating control of the airflow on the basis of more accurate heating instructions, and further facilitating making the temperature of the mixture of sand powder and water acting on the user's teeth more adapted to the user's preferences, so as to improve the user's usage experience of the sandblasting tooth cleaning device.

[0124] In this optional embodiment, the method may further include the following operations:

[0125] Detecting the real-time sand powder temperature and real-time water flow temperature corresponding to the sandblasting and tooth cleaning equipment; wherein the real-time sand powder temperature is the real-time temperature of the sand powder stored in the sandblasting and tooth cleaning equipment, and the real-time water flow temperature is the real-time temperature of the water flow that needs to be mixed with the sand powder in the sandblasting and tooth cleaning equipment;

[0126] Estimate the temperature influence coefficient of the mixture of sand powder, water flow and air flow based on the real-time water flow temperature and the real-time sand powder temperature;

[0127] Determine the target temperature that the airflow needs to reach based on the heating instruction and temperature influence coefficient;

[0128] Optionally, generating a heating control signal corresponding to the heating instruction may include the following operations:

[0129] According to the target temperature, a heating control signal corresponding to the heating instruction is generated.

[0130] It can be seen that this optional embodiment can also generate a heating control signal by analyzing the influence coefficient of the temperature of the sand powder required to be ejected by the airflow and the temperature of the water flow used to mix the sand powder on the heating of the airflow to the target temperature, thereby combining the heating instruction and the temperature influence coefficient to determine the target temperature that the airflow needs to reach. It can improve the temperature influence coefficient of the mixture generated by the sand powder and water flow after the mixed airflow, thereby helping to improve the accuracy of determining the target temperature, and then improve the accuracy of generating the heating control signal, so that the temperature of the mixture of sand powder and water acting on the user's teeth is more consistent with the temperature indicated by the heating instruction.

[0170] In an embodiment of the present invention, optionally, the target voltage signal can be collected through the ADC interface of the single-chip microcomputer provided in the sandblasting and cleaning equipment, which is not limited in the embodiment of the present invention; wherein, the target voltage signal corresponding to the sampling unit is a sampled voltage signal obtained after signal processing (such as filtering processing, signal amplification processing).

[0171] 205. Determine whether there is voltage abnormality in the air heating circuit based on the target voltage signal.

[0172] In the embodiment of the present invention, when step 205 determines that there is a voltage abnormality in the air heating circuit, that is, when the judgment result of step 205 is yes, the operation of step 206 is executed; optionally, when step 205 determines that there is no voltage abnormality in the air heating circuit, that is, when the judgment result of step 205 is no, the operation of step 204 can be re-executed or the process can be terminated, which is not limited in the embodiment of the present invention. Figure 2 The described method takes the operation of re-execution of step 204 as an example, which is not limited in the embodiment of the present invention.

[0173] In the embodiment of the present invention, if there is a voltage abnormality in the air heating circuit, it means that the temperature of the heating control unit of the air heating circuit is abnormal, which will cause the temperature of the airflow flowing through the heating control unit to not match the heating instruction.

[0174] 206. Based on the voltage abnormality, perform an optimization operation corresponding to the voltage abnormality on the sandblasting and tooth cleaning equipment.

[0175] In the embodiment of the present invention, for other detailed descriptions of steps 201 to 203, please refer to the detailed description of steps 101 to 103 in the first embodiment, which will not be repeated in the embodiment of the present invention.

[0176] It can be seen that the method described in the embodiment of the present invention can generate a heating control signal corresponding to the heating instruction after detecting the heating instruction, and input the heating control signal into the air heating circuit to control the heating control unit in the circuit to perform a temperature adjustment operation, so that the temperature of the air flow flowing through the heating control unit is adjusted to the target temperature corresponding to the heating instruction to achieve the effect of air heating. In this way, by adding an air heating function to the sandblasting and tooth cleaning equipment, the air flow required for sandblasting by the sandblasting and tooth cleaning equipment is heated, which can improve the control accuracy of air heating while improving the heating flexibility, heating efficiency and heating accuracy of the mixture of sand powder and water used in the sandblasting and tooth cleaning equipment, thereby reducing the possibility of the patient feeling uncomfortable when the sand-water mixture acts on the user's teeth, and further improving the user's experience of using the sandblasting and tooth cleaning equipment. In addition, it is also possible to determine whether there is a voltage abnormality in the air heating circuit based on the target voltage signal corresponding to the sampling unit obtained by the collection. If so, the sandblasting and tooth cleaning equipment will perform corresponding optimization operations, which can improve the detection efficiency of abnormalities in the air heating process, and can improve the processing efficiency and processing technology of abnormal situations when abnormalities in the air heating process are detected, which is conducive to the efficient optimization of the air heating operation, and further conducive to further improving the heating accuracy and heating safety of the sandblasting and tooth cleaning equipment.

[0177] In an optional embodiment, judging whether there is a voltage abnormality in the air heating circuit according to the target voltage signal may include the following operations:

[0178] Determining a preset voltage interval corresponding to the heating instruction according to the heating instruction; the preset voltage interval includes at least a preset voltage threshold;

[0179] Determining whether a target voltage value corresponding to the target voltage signal is within a preset voltage range;

[0180] When it is determined that the target voltage value corresponding to the target voltage signal is within the preset voltage range, it is determined that there is no voltage abnormality in the air heating circuit;

[0181] When it is determined that the target voltage value corresponding to the target voltage signal is not within the preset voltage range, it is determined that a voltage abnormality exists in the air heating circuit.

[0182] Optionally, the preset voltage interval may include a maximum voltage threshold and / or a minimum voltage threshold, which is not limited in the embodiment of the present invention.

[0183] For example, assuming that the preset voltage range corresponding to the heating instruction is 1.1V-1.3V, if the target voltage value corresponding to the target voltage signal is 1.4V, it is determined that there is a voltage abnormality in the air heating circuit, which is not limited in the embodiment of the present invention.

[0184] It can be seen that this optional embodiment can determine that there is no voltage abnormality in the air heating circuit when it is determined that the target voltage value corresponding to the target voltage signal is in the preset voltage range corresponding to the heating instruction. Otherwise, it is determined that there is a voltage abnormality in the air heating circuit. It can efficiently determine whether there is an abnormality in the air heating circuit based on the voltage value, thereby improving the judgment efficiency and accuracy of voltage abnormalities, which is conducive to improving the timeliness of handling abnormal situations.

[0185] In this optional embodiment, the heating control signal may optionally be a PWM signal.

[0186] Optionally, based on the voltage abnormality, performing optimization operations corresponding to the voltage abnormality on the sandblasting and tooth cleaning equipment may include the following operations:

[0187] Determine a voltage anomaly type corresponding to the voltage anomaly; the voltage anomaly type includes a first anomaly type or a second anomaly type;

[0188] When the voltage abnormality type is the first abnormality type, the duty cycle of the heating control signal is optimized according to the target voltage value and the preset voltage range, and the optimized heating control signal is input to the air heating circuit to control the heating control unit to perform the optimized adjustment operation;

[0189] When the voltage abnormality type is the second abnormality type, the sandblasting and tooth cleaning device is controlled to perform a protection operation; the protection operation includes suspending the heating operation of the air heating circuit and / or stopping the operation of the sandblasting and tooth cleaning device.

[0190] Among them, the optimization and adjustment operation is to adjust the temperature of the heating component in the heating control unit based on the optimized heating control signal, so that the temperature of the air flow flowing through the heating control unit can reach the target temperature; optionally, after performing the above-mentioned operation of optimizing the heating control signal and the optimization and adjustment operation at least once, the voltage anomaly can be eliminated and the temperature of the heating component can be maintained at a temperature value that matches the heating instruction.

[0191] It can be seen that this optional embodiment can also optimize the duty cycle of the heating control signal according to the target voltage value and the preset voltage range when it is determined that the voltage abnormality belongs to the first abnormality type, thereby optimizing the heating condition of the heating control unit in the air heating circuit, and can improve the optimization efficiency and optimization accuracy of the heating control signal, thereby helping to improve the control accuracy of the heating control unit; and when it is determined that the voltage abnormality belongs to the second abnormality type, it can stop the heating operation in time and / or directly shut down the sandblasting and tooth cleaning equipment, which can improve the operation control accuracy of the sandblasting and tooth cleaning equipment while improving the operation safety of the sandblasting and tooth cleaning equipment.

[0192] In this optional embodiment, optionally, determining the voltage anomaly type corresponding to the voltage anomaly may include the following operations:

[0193] Calculating a voltage difference between a target voltage value and a target voltage threshold value; the target voltage threshold value is one of the preset voltage threshold values;

[0194] Determining whether the voltage difference is less than or equal to a preset voltage difference;

[0195] When it is determined that the voltage difference is less than or equal to the preset voltage difference, determining that the voltage abnormality type corresponding to the voltage abnormality is a first abnormality type;

[0196] When it is determined that the voltage difference is greater than the preset voltage difference, the voltage abnormality type corresponding to the voltage abnormality is determined to be the second abnormality type.

[0197] The target voltage threshold is a preset voltage threshold having the smallest difference with the target voltage value among a plurality of preset voltage thresholds.

[0198] Among them, for example, assuming that the preset voltage range corresponding to the heating instruction is 1.1V-1.3V, and the target voltage value corresponding to the target voltage signal is 1.4V, and the preset voltage difference is 0.2V, it can be determined that the target voltage threshold is 1.3V, and the voltage difference is 0.1V. At this time, the voltage difference is less than the preset voltage difference, and the voltage abnormality type corresponding to the voltage abnormality is determined to be the first abnormality type.

[0199] It can be seen that this optional embodiment can also determine that the voltage anomaly type corresponding to the voltage anomaly is the first anomaly type when it is determined that the voltage difference between the target voltage value and the target voltage threshold is less than or equal to the preset voltage difference; otherwise, the voltage anomaly type is determined to be the second anomaly type, which can improve the classification efficiency and classification accuracy of voltage anomalies, thereby facilitating the efficient adoption of different processing measures for different types of voltage anomalies, thereby improving the processing efficiency and processing accuracy of voltage anomalies.

[0200] In another optional embodiment, the method may further include the following operations:

[0201] When it is determined that there is a voltage abnormality in the air heating circuit or it is detected that the real-time airflow temperature of the airflow flowing through the heating control unit does not reach the target temperature, the sandblasting and tooth cleaning device is controlled to stop the sandblasting operation using the above-mentioned airflow, and / or the sandblasting and tooth cleaning device is controlled to send a prompt message to the operator of the sandblasting and tooth cleaning device; wherein the prompt message is used to indicate that the real-time temperature of the current airflow / current sand-water mixture has not reached the target temperature; the prompt message may be expressed in a form of one or more combinations of an indicator light, a voice prompt, a text prompt, and a vibration prompt;

[0202] When it is determined that there is no voltage abnormality in the air heating circuit and it is detected that the real-time air flow temperature of the air flow flowing through the heating control unit reaches the target temperature, the sandblasting and cleaning device is controlled to perform the sandblasting operation using the air flow.

[0203] It can be seen that this optional embodiment can also not allow the sandblasting and tooth cleaning equipment to perform sandblasting operations and / or prompt the operator that the current temperature has not reached the target temperature when there is a voltage abnormality in the air heating circuit or the real-time airflow temperature of the airflow is detected to be less than the target temperature, thereby reducing the possibility of the sandblasting and tooth cleaning equipment spraying a lower temperature airflow or sand-water mixture to the user, which is beneficial to reduce the possibility of the user feeling uncomfortable during the use of the sandblasting and tooth cleaning equipment, and is beneficial to improving the user's experience of the sandblasting and tooth cleaning equipment.
