Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic equipment, and in particular to an intelligent digital ultrasonic device for preventing dry burning. Background Art

[0002] In the existing ultrasonic devices for atomization or cleaning, when there is a lack of water, once the ultrasonic cleaning function is turned on, the ultrasonic transducer will be in a dry-burning state. As the dry-burning working time increases, the ultrasonic transducer component will be damaged, causing the ultrasonic cleaning equipment to fail to work.

[0003] The existing anti-dry burning technical solutions generally use temperature sensors or water level sensors. Whether the temperature sensor is through analog circuits or digital circuits, the hysteresis is relatively serious, the control scheme is relatively complex, and the production and manufacturing costs are high. The water level sensor will cause water level fluctuations due to ultrasonic vibrations. The ultrasonic device used for atomization also has the problem of fog water influence. At present, there is an inaccurate situation when judging that the water level is too low.

[0004] In addition, the existing anti-dry burning solutions are relatively simple, generally only having one or two detection data. When an abnormality occurs in the detection module, the ultrasonic equipment cannot be shut down normally. Summary of the invention

[0005] In view of the above situation, it is necessary to propose an intelligent digital ultrasonic device for preventing dry burning with improved detection accuracy.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: an intelligent digital anti-dry burning ultrasonic device, comprising an ultrasonic transducer assembly, an MCU processor, a multi-component detection controller and an I / O port, the ultrasonic transducer assembly is provided with at least one, the multi-component detection controller comprises a transducer impedance detection module, a transducer power detection module, a transducer frequency detection module, a capacitive reactance component detection module, and an inductive reactance component detection module, the electronic component is connected to the ultrasonic transducer assembly through the I / O port; when at least one of the transducer impedance detection module, the transducer power detection module, the transducer frequency detection module, the capacitive reactance component detection module, and the inductive reactance component detection module detects an abnormality, the MCU processor controls the I / O port to stop outputting a drive signal.

[0007] Furthermore, there are more than two ultrasonic transducer assemblies, and the more than two ultrasonic transducer assemblies are connected in parallel.

[0008] Furthermore, it also includes a power input module, a rectifier energy storage module and a half-bridge / full-bridge inverter module which are connected in sequence.

[0009] Furthermore, it also includes an amplification module and a matching network, the MCU processor is connected to the amplification module, the amplification module is connected to the half-bridge / full-bridge inverter module, the half-bridge / full-bridge inverter module is connected to the matching network, and the matching network is connected to the I / O port.

[0010] Furthermore, it also includes an analog-to-digital conversion module and a comparison module, and the multi-component detection controller is connected to the MCU processor through the comparison module and the analog-to-digital conversion module.

[0011] Furthermore, it also includes a water level detector, which is connected to the MCU processor. When it is detected that the water level meets the preset value, the MCU processor re-outputs the driving signal to the I / O.

[0012] Furthermore, it also includes a protection module, which is started after the MCU processor stops outputting the driving signal to keep the MCU processor in a standby state. The water level detector is connected to the MCU processor, and the protection module is unlocked when it is detected that the water level meets the preset value.

[0013] Furthermore, it also includes a human-computer interaction module, which is connected to the MCU processor, and the human-computer interaction includes at least one of a display screen, an indicator light, and a prompt sound.

[0014] The beneficial effects of the present invention are as follows: the multi-component detection controller includes an impedance detection component, a power detection component, a frequency detection component, a capacitive reactance component, and an inductive reactance component. When any one or more separations are inconsistent with preset parameters, the multi-component detection controller sends a signal to the MCU processor, the MCU processor stops the output of the I / O port, and the ultrasonic power conversion part stops working due to the lack of a driving signal. Multiple components are detected with high accuracy, and all are directly targeted at the detection of the ultrasonic transducer assembly, which can terminate the abnormal state in time, avoid the problem that the ultrasonic transducer assembly cannot be closed in time due to the hysteresis delay problem, improve the safety of the ultrasonic transducer assembly, and on the other hand, extend the service life of the ultrasonic transducer assembly.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a further detailed description of an intelligent digital ultrasonic device for preventing dry burning of the present invention in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Please refer to Figure 1-Figure 5 , an intelligent digital anti-dry-burning ultrasonic device, including an ultrasonic transducer assembly 100, an MCU processor 200, a multi-component detection controller 300 and an I / O port 400, the ultrasonic transducer assembly 100 is provided with at least one, the multi-component detection controller 300 includes a transducer impedance detection module 310, a transducer power detection module 320, a transducer frequency detection module 330, a capacitive reactance component detection module 340, and an inductive reactance component detection module 350, and the electronic component is connected to the ultrasonic transducer assembly 100 through the I / O port 400; when at least one of the transducer impedance detection module 310, the transducer power detection module 320, the transducer frequency detection module 330, the capacitive reactance component detection module 340, and the inductive reactance component detection module 350 detects an abnormality, the MCU processor 200 controls the I / O port 400 to stop outputting a driving signal.

[0029] The multi-component detection controller 300 includes an impedance detection component, a power detection component, a frequency detection component, a capacitive reactance component, and an inductive reactance component. When any one or more separations are inconsistent with the preset parameters, the multi-component detection controller 300 sends a signal to the MCU processor 200, and the MCU processor 200 stops the output of the I / O port 400, and the ultrasonic power conversion part stops working due to the lack of a driving signal. Multiple components are detected with high accuracy, and all are directly targeted at the detection of the ultrasonic transducer assembly 100, which can stop the abnormal state in time, avoid the problem that the ultrasonic transducer assembly 100 cannot be closed in time due to the hysteresis delay problem, improve the safety of the ultrasonic transducer assembly 100, and on the other hand, extend the service life of the ultrasonic transducer assembly 100.

[0030] Please refer to Figure 1 There are more than two ultrasonic transducer assemblies 100, and the more than two ultrasonic transducer assemblies 100 are connected in parallel. That is, the I / O is connected to more than two ultrasonic transducer assemblies 100 respectively, and the multi-component detection controller 300 detects the parameters of the I / O port 400. When one or more ultrasonic transducer assemblies 100 are abnormal, the parameter abnormality can be measured from the I / O port 400.

[0031] Please refer to Figure 2 , and also includes a power input module 500, a rectifier energy storage module 510 and a half-bridge / full-bridge inverter module 520 connected in sequence.

[0032] Please refer to Figure 2 , also includes an amplification module 600 and a matching network 700, the MCU processor 200 is connected to the amplification module 600, the amplification module 600 is connected to the half-bridge / full-bridge inverter module 520, the half-bridge / full-bridge inverter module 520 is connected to the matching network 700, and the matching network 700 is connected to the I / O port 400.

[0033] Please refer to Figure 2 , and also includes an analog-to-digital conversion module and a comparison module. The multi-component detection controller 300 is connected to the MCU processor 200 through the comparison module and the analog-to-digital conversion module. The comparison result of the comparator is converted from an analog signal to a digital signal through the analog-to-digital conversion module, which is convenient for the MCU processor 200 to receive.

[0034] In particular, please refer to Figure 4, and also includes a water level detector, which is connected to the MCU processor 200. When the water level is detected to meet the preset value, the MCU processor 200 re-outputs the drive signal to the I / O. The water level detector has a certain hysteresis when detecting a water level lower than the preset water level, but when the water level is detected to be higher than the preset water level, the accuracy is high and there is no need to consider the hysteresis. It can be understood that since the water level detector is used for fault recovery judgment, the preset water level line does not need to be attached to the bottom, does not need to occupy the bottom position, and can be placed on the side wall close to the bottom, thereby facilitating the installation layout of the parts.

[0035] Please refer to Figure 5 , and also includes a protection module. The protection module is started after the MCU processor 200 stops outputting the driving signal to keep the MCU processor 200 in a standby state. The water level detector is connected to the MCU processor 200. When the water level meets the preset value, the protection module is unlocked. The protection module is set to avoid starting the I / O port 400 again when the water level is too low. Simply, the protection module includes a transistor.

[0036] Please refer to Figure 2 , and also includes a human-computer interaction module 800, which is connected to the MCU processor 200, and the human-computer interaction includes at least one of a display screen, an indicator light, and a prompt sound. The human-computer interaction module 800 is set to remind you to add water source in time when the multi-component detection controller 300 detects an abnormality.

[0037] It can be understood that the connection in this application refers to electrical connection or signal connection.

[0038] In particular, the MCU processor 200, the multi-component detection controller 300, the I / O port 400, the amplification module 600, the half-bridge / full-bridge inverter module 520, the matching network 700, the rectifier module, the analog-to-digital conversion module and the comparison module are integrated on a circuit board through integration technology, and the circuit board is then connected to the AC input module through the AC input interface, which is convenient for installation and connection.

[0039] In summary, the present invention provides an intelligent digital ultrasonic device for preventing dry burning, wherein the multi-component detection controller includes an impedance detection component, a power detection component, a frequency detection component, a capacitive reactance component, and an inductive reactance component. When any one or more separations are inconsistent with the preset parameters, the multi-component detection controller sends a signal to the MCU processor, and the MCU processor stops the output of the I / O port, and the ultrasonic power conversion part stops working due to the lack of a driving signal. Multiple components are used for detection, with high accuracy, and all are directly targeted at the detection of the ultrasonic transducer assembly, which can terminate the abnormal state in time, avoiding the problem that the ultrasonic transducer assembly cannot be closed in time due to the lag delay problem, improving the safety of the ultrasonic transducer assembly, and on the other hand, extending the service life of the ultrasonic transducer assembly.
