Detailed Implementation

[0022] This utility model discloses an ultrasonic cleaning device with a drying function, such as... Figure 1 , Figure 2 and Figure 5As shown, the ultrasonic cleaning equipment includes a main body 1. The top of the outer shell 11 of the main body 1 has a cavity 12. The cavity 12 is divided into a cleaning tank 121 and a drying chamber 122 by a partition. A motor 17 is connected to the wall of the outer shell 11 behind the partition via a first fixing frame. A drive shaft 18 parallel to the longitudinal direction of the main body 1 is fitted to the top of the partition. One end of the drive shaft 18 penetrates the rear wall of the outer shell 11 and is connected to the output end of the motor 17. Swing arm mechanisms 2 are connected to both the front and rear ends of the drive shaft 18. A shelf 3 is connected to the end of the swing arm away from the drive shaft 18. A fan 15 is provided on the wall of the outer shell 11 behind the drying chamber 122. A heating device 16 is provided at the air outlet of the fan 15. A discharge channel 111 is provided in the middle of the bottom surface of the drying chamber 122, extending to the outside of the outer shell 11. The main unit 13 of the main body 1 is provided in the outer shell 11 below the washing pool 121. A control panel 14 is provided on the front end of the outer shell 11. The main unit 13 is electrically connected to the motor 17, the control panel 14, the fan 15 and the heating device 16 respectively.

[0023] It should be further explained that when using ultrasonic cleaning equipment to clean workpieces, the workpiece is first placed in the rack 3. Then, the control panel 14 transmits commands to the main unit 13, which controls the motor 17 to start. The drive shaft 18 rotates under the drive of the motor 17, thereby driving the swing arm mechanism 2 to move the rack 3 into the cleaning tank 121 to be submerged in the cleaning solution. Then, the control panel 14 transmits commands to the main unit 13 to start the ultrasonic cleaning function of the main unit 1. The ultrasonic waves in the liquid disperse, emulsify, and peel off the dirt layer on the surface of the workpiece by utilizing the cavitation, acceleration, and direct flow effects of the ultrasonic waves. After ultrasonic cleaning of the workpiece, the main unit 13 controls the motor 17 to start, and the drive shaft 18 rotates under the drive of the motor 17, thereby moving the rack 3 through the swing arm mechanism 2. The workpiece is then transferred from the cleaning tank 121 to the drying chamber 122 without the need for manual transfer by the operator. After the workpiece is moved into the drying chamber 122, the main unit 13 controls the fan 15 and the heating device 16 to work. The fan 15 blows hot air towards the workpiece to dry it. The cleaning liquid blown off during the drying process can enter the discharge channel 111 and be discharged out of the ultrasonic cleaning equipment. The rack 3 moved into the drying chamber 122 serves as a positioning structure for the workpiece to ensure its stable position during the drying process. This ultrasonic cleaning equipment realizes the ultrasonic cleaning and drying of the workpiece in a fully automatic manner, making the cleaning operation of the ultrasonic cleaning equipment more intelligent and reducing the risk of damage to the surface of the workpiece during the cleaning process.

[0024] It needs to be further explained that, such as Figure 2 and Figure 3As shown, the swing arm mechanism 2 includes a first connecting arm 21 and a second connecting arm 22. The first connecting arm 21 is fixedly connected to both the front and rear ends of the drive shaft 18. One end of the second connecting arm 22 is connected to the end of the first connecting arm 21 away from the drive shaft 18 via a rotating shaft. The other end of the second connecting arm 22 is fixedly connected to one end of the shelf 3.

[0025] When the motor 17 drives the drive shaft 18 to rotate, the first connecting arm 21 will rotate with the drive shaft 18. The second connecting arm 22 will remain in its original state when the first connecting arm 21 rotates around the drive shaft 18, as it is axially connected to the first connecting arm 21. This allows the shelf 3 to move between the washing tank 121 and the drying chamber 122 in a translational manner, preventing the workpieces in the shelf 3 from moving and ensuring that the workpieces in the shelf 3 do not fall out of the shelf 3.

[0026] Specifically, such as Figure 4 As shown, the second connecting arm 22 has a first mating hole 221 at the end away from the first connecting arm 21 that is axially connected to it. The cross-section of the first mating hole 221 is polygonal. Both ends of the bottom of the shelf 3 have mating blocks 31 with the same cross-sectional shape as the first mating hole 221. The end of the mating block 31 away from the shelf 3 has a second mating hole 32 for connecting the limiting screw 4. The diameter of the nut 41 of the limiting screw 4 is larger than the diameter of the first mating hole 221.

[0027] Both ends of the shelf 3 can be connected to the first connecting arm 21 through the engagement between the mating block 31 and the first mating hole 221. The mating block 31 and the first mating hole 221 can restrict the rotation of the shelf 3, thus playing a limiting role. The limiting screw 4 connected to the mating block 31 can limit both sides of the shelf 3 after it is connected to the swing arm mechanism 2, thereby preventing the shelf 3 from swaying back and forth when the swing arm mechanism 2 moves, and further ensuring that the workpiece in the shelf 3 will not fall out of the shelf 3.

[0028] It needs to be further explained that, such as Figure 3 As shown, the shelf 3 is a frame with a number of mesh holes distributed on each wall surface. The shelf 3 has a placement cavity 33 for placing items inside. The shelf 3 has a number of protrusions 34 arranged in a matrix on the surface below the placement cavity 33.

[0029] The mesh on the shelf 3 allows the cleaning fluid in the cleaning tank 121 to enter the placement cavity 33 inside the shelf 3, thereby immersing the workpiece in the placement cavity 33 and using the cleaning fluid as a medium to perform ultrasonic cleaning on the workpiece; while the protrusions 34 can further stabilize the position of the workpiece in the placement cavity 33.

[0030] It needs to be further explained that, such as Figure 1 and Figure 2 As shown, two first electric pumps 5 are mounted on the wall behind the cleaning tank 121 via a second fixed bracket. The output end of the first electric pump 5 extends into the cleaning tank 121, and the first electric pump 5 is electrically connected to the main unit 13.

[0031] The control panel 14 transmits instructions to the host 13, which controls the first electric pump 5 to start. The first electric pump 5 can not only inject cleaning fluid into the cleaning tank 121, but also spray cleaning fluid onto the workpiece after ultrasonic cleaning to wash away the dirt attached to the surface of the workpiece, ensuring that the dirt on the surface of the workpiece is removed.

[0032] It needs to be further explained that, such as Figure 5 and Figure 6 As shown, the outer shell 11 below the partition is provided with a cavity 112 that communicates with the discharge channel 111. A second electric pump 6 is provided in the cavity 112. The input end of the second electric pump 6 extends into the cleaning tank 121, and the output end of the second electric pump 6 faces the location of the discharge channel 111. The second electric pump 6 is electrically connected to the main unit 13.

[0033] The control panel 14 transmits instructions to the host 13, which controls the second electric pump 6 to start. After ultrasonic cleaning of the workpiece, the wastewater remaining in the cleaning tank 121 is pumped out by the second electric pump 6 and discharged into the discharge channel 111. Then, it is discharged out of the ultrasonic cleaning equipment through the discharge channel 111, thereby removing the cleaning waste liquid in the cleaning tank 121.

[0034] Specifically, such as Figure 5 and Figure 6 As shown, the walls of the drying chamber 122 located on both sides of the port of the discharge channel 111 are all inclined surfaces 181, and the portion of the discharge channel 111 near the port connected to the main body 1 is inclined.

[0035] The cleaning fluid blown off the workpiece by the fan 15 can slide down into the discharge channel 111 under the guidance of the inclined surface 181, making it easier for the cleaning fluid in the drying chamber 122 to fall into the discharge channel 111 and be discharged out of the ultrasonic cleaning equipment. The inclined discharge channel 111 near the port connecting to the outside of the main body 1 can also guide the cleaning fluid, making it easier for the cleaning fluid in the discharge channel 111 to be discharged out of the ultrasonic cleaning equipment.

[0036] It needs to be further explained that, such as Figure 5 , Figure 6 and Figure 7 As shown, the top two sides of the outer shell 11 are respectively connected by a first cover plate 7 and a second cover plate 8 via a rotating shaft. The first cover plate 7 covers the opening at the top of the washing tank 121 by rotating, and the second cover plate 8 covers the opening at the top of the drying chamber 122 by rotating. The surface of the second cover plate 8 away from the fan 15 is provided with an exhaust grille 81.

[0037] When ultrasonically cleaning the workpiece, the first cover plate 7 can be placed on top of the cleaning tank 121, thereby forming a closed space in the cleaning tank 121 to prevent external factors from affecting the ultrasonic cleaning inside the cleaning tank 121. When drying the workpiece, the second cover plate 8 can be placed on top of the cleaning tank 121, thereby forming a closed space in the drying chamber 122. This prevents the fan 15 from blowing the cleaning liquid on the workpiece out of the drying chamber 122 and splashing it around the ultrasonic cleaning equipment, thus avoiding a slippery ground. The exhaust grille 81 facilitates the discharge of water vapor from the drying chamber 122.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
