[0002] A sonic motor refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. Its main function is to generate driving torque. It can be used as a power source for electrical appliances or various machines. For example, as the motor core of an electric toothbrush, after the sonic motor is energized, under the control of the control circuit, the sonic motor will circulate and generate a high-frequency vibration, thereby driving the toothbrush head to generate high-frequency vibration.

[0033] A pressure box 27 is provided on the surface of the motor body 3, and the right inner wall of the pressure box 27 is connected to a piston plate 28 through a spring.

The right end of the transmission shaft 37 extends out of the transverse groove 34 and is located in the air intake groove 142. The right end of the transmission shaft 37 is fixedly connected to a brush plate 38, which can be used to clean impurities on the surface of the filter screen 16.

[0036] A buzzer 39 is fixedly connected to the lower inner wall of the mounting shell 1. The buzzer 39 is electrically connected to the PLC controller 2. The buzzer 39 can remind the user of the fixed state of the sonic motor.

[0037] The operating principle of the present invention is now explained as follows: the motor body 3 is installed inside the mounting shell 1, and the fixing frame 4 is fixed by bolts, and then the operator transmits an electrical signal to the PLC controller 2 through the external remote control device. After receiving the electrical signal, the PLC controller 2 will control the micro air pump 141 and the second normally closed control valve 26 to work, and the micro air pump 141 will transport the external gas to the rubber ring 241 and the air pressure tube 32 through the outlet pipe 17 and the delivery pipe 25, so that the rubber ring 241 is inflated, and the rubber ring 241 will drive multiple damping pads 242 to move in the direction close to the mounting shell 1, and use the damping pads 242 to squeeze into the mounting shell 1, thereby reducing the vibration generated by the motor body 3 during operation. At the same time, when the internal air pressure of the rubber ring 241 increases, the external gas will enter the air pressure tube 32 into the air pressure tube 32. In the box 27, the pressure on the left side of the piston plate 28 is the same as the air pressure inside the rubber ring 241, while the air pressure on the right side of the piston plate 28 is less than the air pressure on the left side. Under the action of the air pressure difference, the piston plate 28 will drive the electric contact block 30 to move towards the electric contact plate 31. The electric contact block 30 is electrically connected to the internal power supply (when the motor body 3 is installed inside the ultrasonic toothbrush for use, the internal power supply is the energy storage power supply inside the ultrasonic toothbrush), and the electric contact plate 31 is electrically connected to the PLC controller 2. When the electric contact block 30 and the electric contact plate 31 are in contact, an electrical signal will be transmitted to the PLC controller 2. After receiving the electrical signal, the PLC controller 2 will control the micro air pump 141 to stop working and control the second normally closed control valve 26 to close, so that the motor body 3 is installed and the air pressure inside the rubber ring 241 is within a suitable pressure range;

[0038] In the process of moving the motor body 3 in the mounting shell 1, the motor body 3 will drive the detection box 51 to move to the set position inside the mounting shell 1 through the bent plate 6, and align the upper cone panel 9 and the lower cone panel 11. Since the side walls of the upper cone panel 9 and the lower cone panel 11 on the side close to each other are both inclined surfaces, when the upper cone panel 9 and the lower cone panel 11 are in contact, under the action of the inclined surfaces, the upper cone panel 9 and the lower cone panel 11 will move in the direction away from each other until the ends of the upper cone panel 9 and the lower cone panel 11 are in contact, and the upper cone panel 9 and the lower cone panel 11 will stop moving. After the subsequent motor body 3 vibrates, causing the bolts between the fixing frame 4 and the mounting shell 1 to loosen, the vibration amplitude of the motor body 3 will be further increased, and the motor body 3 drives the detection box 51 and the upper cone panel 9 to vibrate through the bent plate 6. The size of the upper cone panel 9 and the lower cone panel 11 will also increase, and the lower cone panel 11 will be fixedly connected to the mounting shell 1, and the lower cone panel 11 will remain relatively fixed. Therefore, the upper cone panel 9 and the lower cone panel 11 will separate from each other. Under the action of the spring force inside the detection box 51, the lifting plate 52 will drive the upper cone panel 9 and the conductive block 12 to move downward, and will contact the conductive plate 13. The conductive block 12 is electrically connected to the internal power supply, and the conductive plate 13 is electrically connected to the PLC controller 2. When the conductive block 12 and the conductive plate 13 are in contact, an electrical signal will be transmitted to the PLC controller 2. After receiving the electrical signal, the PLC controller 2 indicates that the bolts used to fix the motor body 3 have become loose, and the PLC controller 2 will control the buzzer 39 to work, giving a warning to the surrounding personnel so that the personnel can rotate and reinforce the bolts of the motor body 3 as soon as possible.

[0039] When the motor body 3 is working, the PLC controller 2 will also synchronously control the micro air pump 141 and the first normally closed control valve 23 to work. The micro air pump 141 will transport the gas filtered by the filter screen 16 to the hollow interlayer 18 through the outlet pipe 17, accelerating the flow of the gas inside the hollow interlayer 18, and the heat generated by the motor body 3 when working will escape into the hollow interlayer 18 through the heat dissipation fins 20. When the micro air pump 141 accelerates the flow of air inside the hollow interlayer 18, the heat generated by the motor body 3 when working will flow in the hollow interlayer 18 with the air flow, and in the spiral guide Under the guiding effect of the plate 19, the air flow and heat will be discharged through the heat dissipation port 21, and the air flow will be transported to the transverse groove 34 through the exhaust groove 33, so that the air pressure in the space on the left side of the piston seat 36 will increase, so that the piston seat 36 drives the brush plate 38 to move on the surface of the filter 16 through the transmission shaft 37, and the dust on the surface of the filter 16 is cleaned by the brush plate 38. When the piston seat 36 moves to the right side of the exhaust port 35, the gas will be discharged through the exhaust port 35, and the piston seat 36 will also stop moving. While cooling the motor body 3, the dust on the surface of the filter 16 can also be cleaned.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
