[0002] An ultrasonic cleaning device is a device that uses ultrasonic waves for cleaning. It mainly uses a transducer to convert the acoustic energy of a high-power ultrasonic source into mechanical vibrations. The vibrations are radiated through the cleaning tank wall into the cleaning liquid in the tank. The ultrasonic vibrations agitate the liquid, causing water molecules to collide and squeeze under the action of the ultrasonic waves, ultimately achieving the purpose of cleaning the object.

[0003] Currently, after ultrasonic cleaning devices clean items, impurities and dirt on the surface of the items remain inside the cleaning tank, making the cleaning solution inside the tank dirty. When the content of impurities in the cleaning solution is high, it will affect the cleaning effect, so the cleaning solution needs to be changed frequently, resulting in waste of cleaning solution, which needs to be improved. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ultrasonic cleaning device to solve the problems existing in the background art.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The ultrasonic cleaning device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1:

[0022] like Figure 1-5 As shown, an ultrasonic cleaning device includes a cleaning housing 1, a cleaning tank 2 fixedly installed inside the cleaning housing 1, a cleaning liquid inside the cleaning tank 2, a plurality of ultrasonic transducers 3 fixedly installed at the bottom of the cleaning tank 2, a cleaning mesh frame 5 inside the cleaning housing 1, the upper part of the outer wall of the cleaning mesh frame 5 overlapping the top of the cleaning tank 2, iron positioning blocks 51 fixedly connected to both sides of the outer wall of the cleaning mesh frame 5, limit openings 52 opened on both sides of the top of the cleaning tank 2, the outer wall of the iron positioning block 51 inserted into the inside of the limit opening 52, a magnetic sheet 53 fixedly connected to the bottom of the inner wall of the limit opening 52, and the bottom of the iron positioning block 51 magnetically connected to the top of the magnetic sheet 53.

[0023] In this embodiment, the items to be cleaned are placed in the cleaning mesh frame 5 inside the cleaning tank 2, and ultrasonic waves are generated by the ultrasonic transducer 3 to facilitate ultrasonic cleaning of the items. After cleaning, the cleaning mesh frame 5 can be moved from inside the cleaning tank 2 to facilitate the collection of multiple cleaned items. The cleaning mesh frame 5 is then placed back inside the cleaning tank 2, and the iron positioning blocks 51 on both sides of the cleaning mesh frame 5 are inserted into the limiting ports 52. At the same time, the bottom of the iron positioning blocks 51 is magnetically attracted to the top of the magnetic sheet 53 to increase the stability of the cleaning mesh frame 5.

[0024] Example 2:

[0025] like Figure 1-5 As shown, a circulating filtration mechanism 4 is provided on the lower left side of the cleaning machine housing 1. The circulating filtration mechanism 4 includes a filter tank 41, and a filter element 411 is movably fitted inside the filter tank 41. The filter element 411 has an upper filter screen 412, an activated carbon adsorption layer 413, and a lower filter screen 414 installed from top to bottom. Multiple drain holes are opened at the bottom of the filter element 411. A first conduit 42 is fixedly installed in the middle of the bottom of the cleaning tank 2. A solenoid valve 43 is installed on the first conduit 42. A water pump 44 is fixedly installed on the left side of the bottom of the inner wall of the cleaning machine housing 1. One end of the first conduit 42 is fixedly connected to the water pump 44's suction end. A second conduit 45 is fixedly connected to the water pump 44's drain end. One end of the second conduit 45 is fixedly connected to the upper right side of the filter tank 41. A third conduit 46 is fixedly installed in the middle of the bottom of the filter tank 41. One end of the third conduit 46 is fixedly connected to the upper left side of the inside of the cleaning tank 2. A drain pipe 6 is fixedly connected to the lower right side of the cleaning tank 2. A drain valve 7 is installed on the drain pipe 6.

[0026] In this embodiment, the cleaning solution inside the cleaning tank 2 is easily drawn into the filter tank 41 through the cooperation of the first conduit 42, the solenoid valve 43, the water pump 44 and the second conduit 45. The solution is then filtered through the filter element 411, the upper filter screen 412 and the lower filter screen 414. At the same time, the activated carbon adsorption layer 413 adsorbs the dirt inside the cleaning solution, which facilitates multiple filtration of the cleaning solution. The filtered cleaning solution is then discharged into the cleaning tank 2 through the third conduit 46, which facilitates the circulation and filtration of the cleaning solution and reduces the frequency of cleaning solution replacement. If the cleaning solution needs to be replaced after a long period of use, the drain valve 7 can be opened to discharge the cleaning solution inside the cleaning tank 2 through the drain pipe 6.

[0027] Example 3:

[0028] like Figure 1-5As shown, a sealing cap 416 is threadedly connected to the top of the inner wall of the filter tank 41. Connecting rods 417 are fixedly connected to both sides of the bottom of the sealing cap 416. Limiting blocks 418 are fixedly connected to both sides of the top of the filter element 411. The bottom end of the connecting rod 417 is inserted into the inside of the limiting block 418. A bolt 419 is threadedly connected to one side of the limiting block 418. One end of the bolt 419 is threadedly connected to the inside of the connecting rod 417 on one side. A sealing ring 415 is fixedly embedded inside the filter tank 41. The inner wall of the sealing ring 415 is movably sleeved on the outer wall of the filter element 411.

[0029] In this embodiment, the sealing ring 415 facilitates increased sealing between the outer wall of the filter element 411 and the inner wall of the filter tank 41. When the filter element 411 needs to be replaced, the operator screws off the sealing tank cover 416. The sealing tank cover 416, through the connecting rod 417, the limiting block 418, and the bolt 419, pulls the filter element 411 out of the filter tank 41. Then, the bolt 419 is screwed off, and the bottom end of the connecting rod 417 is removed from the limiting block 418, making it easy to separate the filter element 411 from the sealing tank cover 416. Then, the bolt 419 is used to install the limiting block 418 on the top of the new filter element 411 and the bottom end of the connecting rod 417 together, making it easy to replace the filter element 411.

[0030] In summary, as Figure 1-5 As shown, this ultrasonic cleaning device allows the items to be cleaned to be placed inside the cleaning mesh frame 5. High-frequency vibrations from the ultrasonic transducer 3 generate ultrasonic waves, which are then transmitted to the cleaning fluid inside the cleaning tank 2 for ultrasonic cleaning. After cleaning, the cleaning mesh frame 5 is moved upwards, causing the iron positioning block 51 to move out of the limiting port 52. Simultaneously, the cleaning mesh frame 5 removes multiple cleaned items from inside the cleaning tank 2. If the cleaning fluid needs to be circulated and filtered, the solenoid valve 43 and water pump 44 are activated to draw the cleaning fluid from inside the cleaning tank 2 into the filter tank 41. The fluid then passes through the filter element 411, upper filter screen 412, activated carbon adsorption layer 413, and lower filter screen 414 to filter and adsorb impurities and contaminants in the cleaning fluid. The fluid is then discharged into the cleaning tank 2 through the No. 3 conduit 46. This method facilitates the circulation and filtration of the cleaning fluid. The sealed tank cover 416 is removed by screwing it down, allowing the filter element 411 to be removed from inside the filter tank 41 for replacement.
