[0016] A preferred specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0017] See also Figure 1 The present embodiment provides an ultrasonic cleaning device capable of preventing electromagnetic wave interference, comprising a cleaning container, a water inlet device, an ultrasonic generating device, a main control module 4, a shell 5, a control terminal 61, a power terminal 62, a first magnetic ring 71 and a second magnetic ring 72. The water inlet device is connected to the cleaning container, and comprises a water inlet valve 21 and a water pump 22. The ultrasonic generating device comprises a generator 31, an ultrasonic power board 32 and an ultrasonic transducer 33. The main control module 4 can be controlled to control the water inlet device to transport water to the cleaning container, and control the ultrasonic generating device to generate ultrasonic waves to radiate to the water. The object can be cleaned by placing it in the cleaning container. The shell 5 is used to encapsulate the water inlet device. The ultrasonic transducer 33 is placed on the periphery of the shell 5, the control end 61 and the power connection end 62 are arranged on the periphery of the shell 5, the control end 61 is electrically connected to the main control module 4 through the first wire 101, and the power connection end 62 is electrically connected to the main control module 4 through the second wire 102. The first magnetic ring 71 is arranged between the control end 61 and the shell 5, and is penetrated by the first wire 101. The second magnetic ring 72 is arranged between the power connection end 62 and the shell 5, and is penetrated by the second wire 102. The matching mode between the first magnetic ring 71 and the second magnetic ring 72 and their corresponding wires is shown in the attached Figure 2 , the magnetic ring is arranged on the periphery of the conductor.

[0018] The power connection terminal 62 is such as a power plug for connecting to the mains, and the control terminal 61 is such as a control panel, through which the operator can control the operation of the ultrasonic cleaning equipment.

[0019] See also Figure 1 In order to ensure the anti-interference effect of the magnetic ring, the distance between the far end of the first magnetic ring 71 and the shell 5, and the distance between the far end of the second magnetic ring 72 and the shell 5 are both less than or equal to 250 mm, that is, the farthest distance between the magnetic ring and the shell 5 cannot exceed 250 mm.

[0020] See also Figure 1 As an improved solution, the ultrasonic power board 32 and the ultrasonic transducer 33 are connected via a third wire 103. A third magnetic ring 73 is also provided in the shell 5. The third wire 103 runs through the third magnetic ring 73. Preferably, in order to further improve the anti-interference effect in the shell 5, the third wire 103 is wrapped around the third magnetic ring 73 three times.

[0021] See also Figure 1As an improved solution, it also includes a filter 81 located in the housing 5 and connected to the main control module 4 and the ultrasonic power board 32. The filter 81 is connected to a ground wire 82 extending out of the housing 5 and connected to the power terminal 62.

The metal layer may be, for example, aluminum foil or copper foil. By setting the shielding layer 9, interference signals may be effectively shielded.

[0024] See also Figure 1 As an improved solution, the third wire 103 is made of pure copper. When the third wire 103 made of pure copper is in an environment of electromagnetic interference signals, it will absorb part of the electromagnetic interference signals, thereby reducing the signal strength. At the same time, the presence of pure copper material may also change the propagation path and direction of the electromagnetic interference signal, further affecting its distribution in space and reducing the radiation of the interference signal.

[0025] Compared with the prior art, the ultrasonic cleaning device provided by the utility model effectively eliminates electromagnetic interference signals by respectively arranging the first magnetic ring 71 and the second magnetic ring 72 between the shell 5 and the control end 61 and the power connection end 62, thereby preventing the electromagnetic interference signal from being radiated from the outside of the box to the surrounding environment, and also preventing the electromagnetic signal from being transmitted into the circuit through the wire. Furthermore, an electric wire is also arranged to ensure the stability of the potential and prevent electromagnetic interference caused by the potential difference. In addition, a filter 81 is also arranged to eliminate the interference signal on the wire through conduction filtering, and a third magnetic ring 73 and a shielding layer 9 are also arranged, and the third wire 103 is set to be made of pure copper, thereby further eliminating the electromagnetic interference of the ultrasonic transducer 33, preventing the electromagnetic signal from radiating outward and avoiding the influence of external electromagnetic interference signals. By adopting the above effective anti-electromagnetic interference measures, the external electromagnetic interference signal can be effectively shielded or weakened to ensure the normal operation of the electronic components and circuits inside the equipment, thereby improving the stability and reliability of the equipment, and preventing the electromagnetic interference signal generated by the ultrasonic cleaning equipment from radiating to the surrounding environment.
