Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning equipment technology, and more specifically to an ultrasonic cleaning device based on CNC tool coating pretreatment. Background Technology

[0002] An ultrasonic cleaning device consists of an ultrasonic generator, an ultrasonic transducer, a cleaning tank, and a cleaning basket for carrying the workpiece. The ultrasonic generator produces a high-frequency electrical signal, which drives the ultrasonic transducer to convert electrical energy into mechanical vibration, thereby forming dense micro-cavitation bubbles in the cleaning fluid in the cleaning tank. When these bubbles burst, they generate strong local impact and cleaning effect, effectively removing oil and impurities adhering to the surface of the tool. When a coating process is involved in the production of tools, the tool surface must be thoroughly cleaned before coating to ensure surface cleanliness. Most existing technologies use ultrasonic cleaning devices to clean tools before coating.

[0003] However, the existing technology has the following problems:

[0004] When using existing ultrasonic cleaning equipment, workers usually need to place a batch of tools in a cleaning basket, then place the cleaning basket in a cleaning box. After cleaning, the cleaning basket is taken out, the tools are removed, and then the next batch of tools is placed. The entire cleaning process is done in batches and requires manual intervention, resulting in limited work efficiency and making it difficult to adapt to continuous conveyor line production processes. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasonic cleaning device based on CNC tool coating pretreatment to solve the above problems. It aims to overcome the shortcomings of existing ultrasonic cleaning devices that use batch cleaning, have limited operating efficiency, and are difficult to adapt to continuous conveyor line production processes, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides an ultrasonic cleaning device based on CNC tool coating pretreatment, comprising an ultrasonic cleaning chamber, a conveying assembly inside the ultrasonic cleaning chamber, the conveying assembly including multiple chain shafts, the multiple chain shafts being sequentially hinged to form a chain conveyor belt, and a drive mechanism for supporting and driving the chain conveyor belt to circulate; support components for lifting the tools are provided on the chain shafts; a feeding assembly and a discharge plate are respectively connected to both ends of the ultrasonic cleaning chamber; the feeding assembly feeds the tools one by one onto the support components when the chain conveyor belt circulates, and the chain conveyor belt drives the tools on the support components to pass through the ultrasonic cleaning chamber and slide out through the discharge plate.

[0008] Preferably, the driving mechanism includes two pairs of sprockets and two pairs of arc-shaped support plates. Two rotating shafts are rotatably installed inside the ultrasonic cleaning chamber. The two pairs of sprockets are respectively connected to the outer walls of the two rotating shafts. The two pairs of arc-shaped support plates are installed inside the ultrasonic cleaning chamber. Smooth rods are respectively connected to both ends of the sprockets. When the two smooth rods move, they slide in contact with the top of the arc-shaped support plates. The chain conveyor belt is sleeved on the two pairs of arc-shaped support plates through the smooth rods at both ends of the multiple sprockets. The two pairs of sprockets mesh with the chain conveyor belt. The ultrasonic cleaning chamber is equipped with a first motor for driving the rotating shafts to rotate.

[0009] Preferably, the support assembly includes two lifting blocks, both of which are slidably connected to the inner wall of the chain shaft, and each lifting block has a notch.

[0010] Preferably, the chain shaft has cavities at both ends, the optical rod is slidably connected to the chain shaft, and the optical rods at both ends of the chain shaft pass through the two cavities respectively. One end of the optical rod protrudes from the end of the chain shaft, and the other end of the optical rod is connected to a connecting block. The two connecting blocks are slidably connected to two supporting blocks respectively. A stopper is connected to the outer wall of the optical rod, and the stopper is slidably connected to the inner wall of the cavity. A first spring is connected between the stopper and the inner wall of the cavity. Two arc-shaped blocks are installed on the inner wall of the ultrasonic cleaning box. The arc-shaped blocks have protruding arc surfaces. When the chain shaft moves, it passes between the two arc-shaped blocks. When the end of the optical rod protruding from the chain shaft moves, it contacts the protruding arc surface and is subjected to the reaction force of the protruding arc surface, causing it to contract into the cavity.

[0011] Preferably, the sliding trajectory of the lifting block on the inner wall of the chain shaft is inclined, and the sliding trajectories of the two lifting blocks are distributed in a figure-eight shape.

[0012] Preferably, the chain shaft is provided with a jet assembly, which includes a jet tube. A one-way liquid inlet pipe and a one-way liquid outlet pipe are connected through the chain shaft cavity. The jet tube is rotatably connected between the two one-way liquid outlet pipes. A nozzle is opened on the jet tube and the nozzle is located below the two lifting blocks.

[0013] Preferably, the outer wall of the jet tube is connected to two grooved plates, and the grooved plates are provided with corrugated grooves. The bottom of the two connecting blocks is respectively connected to a sliding shaft, and the two sliding shafts are slidably connected to the corrugated grooves of the two grooved plates. When the sliding shafts slide along the corrugated grooves, they can drive the grooved plates and the jet tube to rotate back and forth.

[0014] Preferably, the feeding assembly includes a hopper and a trough. The hopper is mounted on the ultrasonic cleaning chamber, and the trough is rotatably connected inside the hopper.

The first discharge port is located above the trough, and the second discharge port is located below the trough. The hopper is equipped with a second motor for driving the trough to rotate. When the trough rotates, the slots pass through the first discharge port and the second discharge port in sequence. As the slot passes through the second discharge port, one of the chain shafts and its upper support block pass below the discharge port.

[0015] Preferably, the discharge plate is installed at the end of the ultrasonic cleaning box away from the feeding assembly. The discharge plate is inclined. When the chain shaft and the lifting block above it move, they pass through the discharge plate and the cutting tool above it is placed onto the discharge plate.

[0016] Preferably, the ultrasonic cleaning chamber is equipped with a scraping assembly, which includes two slides and two slide seats. The ultrasonic cleaning chamber is equipped with an inlet pipe and an outlet pipe. The bottom of the ultrasonic cleaning chamber has a slope facing the outlet pipe. The two slides are slidably connected to the ultrasonic cleaning chamber along the slope. Multiple scraper plates are rotatably connected to the slides. Fins are connected to the scraper plates. The two slide seats are vertically slidably connected to the inner walls of the front and rear sides of the ultrasonic cleaning chamber. A curved block is connected to the slide seat. Two connecting rods are hinged to the bottom of the curved block. The two connecting rods are respectively hinged to the two slides. The curved block is located on the movement trajectory of the guide rod. A second spring is connected between the bottom of the slide seat and the inner wall of the ultrasonic cleaning chamber.

[0017] The beneficial effects are:

[0018] 1. This ultrasonic cleaning device based on CNC tool coating pretreatment uses a combination of a conveying component, a feeding component, and a discharge plate to feed the tool into the ultrasonic cleaning chamber. The tool is then conveyed by a chain conveyor belt, allowing it to undergo ultrasonic cleaning as it passes through the chamber. Afterward, the tool slides to the next process via the discharge plate. The entire process requires no manual intervention, achieving automated and continuous tool cleaning, making the tool production line more seamless and improving production efficiency.

[0019] 2. This ultrasonic cleaning device based on CNC tool coating pretreatment, through the setting of the support component, allows the two lifting blocks to move while maintaining the lifting state during the cleaning process. This changes the contact area between the lifting blocks and the tool, avoiding prolonged contact between the lifting blocks and the same part of the tool, which would obstruct that part and affect the overall cleaning effect of the tool surface. Furthermore, when the two lifting blocks approach each other, they can move the tool upward, further increasing the contact area between the tool surface and the cleaning fluid per unit time, thereby optimizing the cleaning effect.

[0020] 3. This ultrasonic cleaning device based on CNC tool coating pretreatment, through the setting of the slag scraping component, allows impurities in the ultrasonic cleaning box to be deposited at the bottom. The reciprocating movement of multiple shovels causes the shovels to scrape the impurities deposited on the slope towards the water outlet pipe, so that the impurities accumulate at the water outlet pipe. This makes it easier for most of the impurities to be discharged through the water outlet pipe during drainage, reducing the amount of impurities remaining inside the ultrasonic cleaning box when it is drained, thereby shortening the subsequent cleaning time of the ultrasonic cleaning box.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] The first embodiment of the present invention is as follows:

[0045] Please see Figure 1 - Figure 4An ultrasonic cleaning device based on CNC tool coating pretreatment includes an ultrasonic cleaning chamber 1, which contains an ultrasonic generator comprising multiple ultrasonic transducers evenly distributed within the chamber. The ultrasonic cleaning chamber 1 also contains a conveying assembly 2, which includes multiple chain shafts 23 sequentially hinged to form a chain conveyor belt. The conveying assembly 2 includes a drive mechanism for supporting and driving the chain conveyor belt's cyclical movement. Includes two pairs of sprockets 22 and two pairs of arc-shaped support plates 24. Two rotating shafts 21 are rotatably installed inside the ultrasonic cleaning chamber 1. The two pairs of sprockets 22 are respectively connected to the outer walls of the two rotating shafts 21. The two pairs of arc-shaped support plates 24 are installed inside the ultrasonic cleaning chamber 1. Smooth rods 32 are connected to both ends of the sprocket shaft 23. When the two smooth rods 32 move, they slide in contact with the top of the arc-shaped support plates 24. The pair of arc-shaped support plates 24 are located on the front inner wall and the rear inner wall of the ultrasonic cleaning chamber 1, respectively. The sprocket shaft 23 can rest on the pair of arc-shaped support plates 24 via the two smooth rods 32 (e.g., ...). Figure 3 As shown), the chain conveyor belt is supported by two pairs of arc-shaped support plates 24 with the smooth rods 32 at both ends of multiple chain shafts 23. Two pairs of sprockets 22 mesh with the chain conveyor belt. The two ends of the chain shafts 23 are respectively in contact with two sprockets 22 of the same pair, so that a pair of sprockets 22 can provide stable support for the chain shafts 23. The two pairs of arc-shaped support plates 24 and the two pairs of sprockets 22 together constitute the support structure for the entire chain conveyor belt. The sprockets 22 can drive the conveyor belt to circulate through the meshing action by rotating. The ultrasonic cleaning box 1 is equipped with a first motor for driving the rotating shaft 21 to rotate. The chain conveyor belt is divided into a carrying section and a return section. The carrying section is the section of the chain conveyor belt located at the top where the cutting tool is conveyed, and the return section is the section located at the bottom where it does not contact the cutting tool. The two ends of the carrying section are raised upwards, and the middle part of the carrying section is concave downwards (as shown). Figure 2 As shown), the two ends of the bearing section protrude from the surface of the cleaning fluid in the ultrasonic cleaning tank 1, while the middle part of the bearing section is immersed in the cleaning fluid. The two ends of the bearing section are used for feeding and discharging, respectively. When the tool is located in the middle part of the bearing section, it is immersed in the cleaning fluid for ultrasonic cleaning.

[0046] Furthermore, the chain shaft 23 is provided with a support assembly 3 for lifting the tool. The support assembly 3 includes two lifting blocks 31, both of which are slidably connected to the inner wall of the chain shaft 23. The lifting blocks 31 are provided with notches. Each individual chain shaft 23 can lift one tool through the two lifting blocks 31. As the chain conveyor belt circulates, the chain shaft 23 drives the tool through the two lifting blocks 31 to pass through the ultrasonic cleaning box 1 to complete the ultrasonic cleaning operation.

[0047] Furthermore, the ultrasonic cleaning chamber 1 is connected to a feeding assembly 5 and a discharge plate 6 at both ends. The feeding assembly 5, during the cyclical movement of the chain conveyor belt, feeds the cutters one by one onto the support assembly 3. The chain conveyor belt drives the cutters on the support assembly 3 through the ultrasonic cleaning chamber 1 and then slides them out through the discharge plate 6. The feeding assembly 5 and the discharge plate 6 are located at opposite ends of the bearing section. When the chain shaft 23 and the lifting block 31 above it pass, the feeding assembly 5 can feed one cutter onto two lifting blocks 31. When the two lifting blocks 31 carrying the cutter pass through the discharge plate 6, the chain shaft 23 moves to a downward turn, allowing... The two lifting blocks 31 are tilted, and the cutter slides down onto the discharge plate 6 by its own gravity, completing the cleaning and discharge. The feeding component 5 and the discharge plate 6 can connect the previous process and the next process, respectively, thereby connecting the ultrasonic cleaning box 1 to the cutter production line. The cutter is put into the ultrasonic cleaning box 1 through the feeding component 5 and transported by the chain conveyor belt, so that the cutter completes ultrasonic cleaning as it passes through the ultrasonic cleaning box 1. Then it slides to the next process through the discharge plate 6. The whole process does not require manual intervention, realizing automated continuous cutter cleaning, making the cutter production line connection smoother and improving production efficiency.

[0048] Based on the above embodiments, the second embodiment of the present invention is as follows:

[0049] Please see Figure 5 - Figure 7The chain shaft 23 has cavities at both ends. A smooth rod 32 is slidably connected to the chain shaft 23. The smooth rod 32 at both ends of the chain shaft 23 passes through the two cavities. One end of the smooth rod 32 protrudes from the end of the chain shaft 23, and the other end is connected to a connecting block 33. The two connecting blocks 33 are slidably connected to two supporting blocks 31. A stopper 34 is connected to the outer wall of the smooth rod 32, and the stopper 34 is slidably connected to the inner wall of the cavity. A first spring connects the stopper 34 to the inner wall of the cavity. Two arc-shaped blocks 25 are installed on the inner wall of the ultrasonic cleaning chamber 1. Each arc-shaped block 25 has a protruding arc surface. When the chain shaft 23 moves, it passes between the two arc-shaped blocks 25. When the end of the smooth rod 32 protruding from the chain shaft 23 moves, it contacts the protruding arc surface and is subjected to the reaction force of the protruding arc surface, causing it to retract into the cavity. When the chain shaft 23 moves between the two arc-shaped blocks 25, the end of the smooth rod 32 protruding from the chain shaft 23... The convex arc surface of the arc block 25 contacts the light rod 32, and the convex arc surface applies a reaction force to the light rod 32 with its own arc surface, thereby pushing the light rod 32 to retract into the cavity of the chain shaft 23, so that the two light rods 32 move closer to each other. When the light rod 32 moves, it drives the connecting block 33 to move synchronously, so that when the two connecting blocks 33 move closer to each other, they drive the two lifting blocks 31 to slide along the inner wall of the chain shaft 23 and move closer to each other. At the same time, the plug 34 slides in the cavity and compresses the first spring. When the chain shaft 23 disengages from the convex arc surface, the first spring uses its elastic force to push the plug 34 and the light rod 32 to slide back to their original position. The lifting blocks 31 are then reset. The two lifting blocks 31 move while maintaining the lifting state, which can change the contact part with the tool and avoid the lifting blocks 31 from contacting the same part of the tool for a long time, thus avoiding obstruction of that part and affecting the overall cleaning effect of the tool surface.

[0050] It is worth noting that the two curved blocks 25 are provided with multiple protruding curved surfaces, and the light rod 32 can trigger the lifting block 31 to move every time it passes through a protruding curved surface.

[0051] Furthermore, the sliding trajectory of the lifting block 31 on the inner wall of the chain shaft 23 is inclined. When the lifting block 31 slides, it can slide diagonally upward. The sliding trajectories of the two lifting blocks 31 are distributed in a figure-eight shape. When the two lifting blocks 31 approach each other, they slide along the sliding trajectory between themselves and the chain shaft 23. Therefore, when the two lifting blocks 31 approach each other, they can also move upward at the same time. The connecting block 33 and the lifting block 31 are vertically slidingly connected. When the connecting block 33 pushes the lifting block 31 to move, it supports the lifting block 31 to slide vertically on the connecting block 33. This allows the two lifting blocks 31 to drive the tool above them to move upward a certain distance when they approach each other. When the two lifting blocks 31 move away from each other, they drive the tool to move downward and reset. This allows the tool to move horizontally in the cleaning fluid while also performing a compound up-and-down motion, further increasing the contact area between the tool surface and the cleaning fluid per unit time, thereby optimizing the cleaning effect.

[0052] Based on the above embodiments, the third embodiment of the present invention is as follows:

[0053] Please see Figure 6 - Figure 8 A jet assembly 4 is provided on the chain shaft 23. The jet assembly 4 includes a jet pipe 43. A one-way inlet pipe 41 and a one-way outlet pipe 42 are connected through the cavity of the chain shaft 23. One-way valves are respectively provided in the one-way inlet pipe 41 and the one-way outlet pipe 42. The jet pipe 43 is rotatably connected between the two one-way outlet pipes 42. A nozzle is opened on the jet pipe 43 and is located below the two lifting blocks 31. The one-way inlet pipe 41, the cavity, and the one-way outlet are all connected. A one-way flow channel is formed between pipe 42 and jet pipe 43. Cleaning fluid can be drawn into the cavity through one-way inlet pipe 41. One-way inlet pipe 41 and one-way outlet pipe 42 are located on the side of the cavity away from the stopper disc 34. When the polished rod 32 contacts the convex arc surface, the stopper disc 34 begins to move closer to one-way inlet pipe 41 and one-way outlet pipe 42, thereby compressing the cleaning fluid in the cavity and causing the cleaning fluid to be injected into jet pipe 43 through one-way outlet pipe 42. After the polished rod 32 disengages from the convex arc surface, the stopper disc 34 is reset by the elastic force of the first spring. At this time, the stopper disc 34 moves away from the one-way liquid inlet pipe 41, thereby creating a negative pressure in the cavity. This causes the one-way liquid inlet pipe 41 to draw external cleaning fluid into the cavity for replenishment. The one-way liquid inlet pipe 41 is equipped with a filter head, which will not draw impurities into the cavity. Therefore, when the two polished rods 32 on the chain shaft 23 contact the convex arc surface, the cleaning fluid in the two cavities is simultaneously injected into the jet pipe 43 through the two one-way drain pipes 42. The jet pipe 43 then sprays the cleaning fluid upward through the nozzle to form a jet. The jet is directed towards the cutter on the two lifting blocks 31, so that the cutter optimizes the cleaning effect by contacting the jet. In particular, the part of the cutter bottom that was previously in contact with the lifting block 31 can be quickly cleaned after being exposed by the jet, thereby ensuring the overall cleaning effect of the cutter.

[0054] In addition, the outer wall of the jet pipe 43 is connected to two groove plates 44, which have corrugated grooves. The bottom of the two connecting blocks 33 is connected to sliding shafts 45 respectively. The two sliding shafts 45 are slidably connected to the corrugated grooves of the two groove plates 44. When the sliding shafts 45 slide along the corrugated grooves, they can drive the groove plates 44 and the jet pipe 43 to rotate back and forth. When the two connecting blocks 33 approach each other, the two connecting blocks 33 drive the two sliding shafts 45 to slide in the corrugated grooves of the two groove plates 44. The corrugated grooves are wavy, and the sliding shafts 45 slide in a straight line. Therefore, when the sliding shafts 45 slide in the corrugated grooves, they can continuously apply force to the edge of the corrugated grooves, so that the groove plates 44 and the jet pipe 43 can match the sliding trajectory of the sliding shafts 45 through the reciprocating rotation. The two groove plates 44 are mirror images, so that the jet pipe 43 can also rotate back and forth while spraying the cleaning fluid, so that the sprayed jet rises in an oscillating manner, thereby expanding the contact range of the jet and further optimizing the cleaning effect of the jet on the tool.

[0055] Based on the above embodiments, the fourth embodiment of the present invention is as follows:

[0056] Please see Figure 2 , Figure 9 - Figure 11 The feeding assembly 5 includes a hopper 51 and a trough 52. The hopper 51 is mounted on the ultrasonic cleaning chamber 1, and the trough 52 is rotatably connected inside the hopper 51. The trough 52 has multiple slots, each capable of holding only one tool. The hopper 51 has a first discharge port and a second discharge port. The first discharge port is located above the trough 52, and the second discharge port is located below the trough 52. The hopper 51 is equipped with a second motor for driving the rotation of the trough 52. As the trough 52 rotates, the slots pass through the first and second discharge ports in sequence. Simultaneously, as the slot passes through the second discharge port, one of the chain shafts 23 and its upper support block 31 pass below the discharge port. The tools to be cleaned are conveyed into the hopper 51 through the previous process, and the second motor drives the trough 52 to rotate, causing the slots on the trough 52 to rotate. Upon reaching the first discharge port, a cutting tool is received. As the groove cylinder 52 continues to rotate, the groove containing the cutting tool moves to the second discharge port. The cutting tool falls from the second discharge port due to gravity. The first motor and the second motor are controlled by the same control system. The control system sets the speed of the first motor and the second motor so that when each chain shaft 23 passes through the second discharge port, one of the grooves of the groove cylinder 52 can pass through the second discharge port exactly, so that the groove, the second discharge port and the chain shaft 23 are on the same vertical line. Therefore, when a chain shaft 23 and the lifting block 31 move to the bottom of the second discharge port, a groove cylinder 52 with a cutting tool coincides with the second discharge port. The cutting tool falls onto the two lifting blocks 31 of the chain shaft 23 due to gravity, realizing automatic feeding.

[0057] It is worth noting that the discharge plate 6 is installed at the end of the ultrasonic cleaning box 1 away from the feeding assembly 5. The discharge plate 6 is inclined. When the chain shaft 23 and the lifting block 31 above it move, they pass through the discharge plate 6 and drop the cutting tool above it onto the discharge plate 6. The discharge plate 6 is located at the junction of the carrying section and the return section of the chain conveyor belt. When the chain shaft 23 passes through this position, it will start to turn downwards and flip. Therefore, when the chain shaft 23 passes through the discharge plate 6, the lifting block 31 on the chain shaft 23 tilts towards the direction of the discharge plate 6, causing the cutting tool above it to fall onto the discharge plate 6. The cutting tool then slides through the inclined discharge plate 6 to the next process.

[0058] Based on the above embodiments, the fifth embodiment of the present invention is as follows:

[0059] Please see Figure 2 , Figure 12 , Figure 13The ultrasonic cleaning chamber 1 is equipped with a scraping assembly 7, which includes two slides 71 and two slides 74. The ultrasonic cleaning chamber 1 is equipped with an inlet pipe and an outlet pipe. The bottom of the ultrasonic cleaning chamber 1 has a slope facing the outlet pipe. The two slides 71 are slidably connected to the ultrasonic cleaning chamber 1 along the slope. Multiple scraper plates 72 are rotatably connected to the slides 71, and fins 73 are connected to the scraper plates 72. The two slides 74 are vertically slidably connected to the inner walls of the front and rear sides of the ultrasonic cleaning chamber 1, respectively. Curved blocks 75 are connected to the slides 74. Two connecting rods 76 are hinged to the bottom of the curved blocks 75. The two connecting rods 76 are respectively connected to the two slides 74. The frame 71 is hinged, and the curved block 75 is located on the movement trajectory of the guide rod 32. A second spring connects the bottom of the slide 74 to the inner wall of the ultrasonic cleaning chamber 1. When the chain shaft 23 drives the guide rod 32 to the position of the curved block 75, the guide rod 32 contacts and presses the curved block 75 during the movement, thereby pushing the curved block 75 and the slide 74 downward. The slide 74 compresses the second spring. When the guide rod 32 disengages from the curved block 75, the slide 74 resets using the elastic force of the second spring, and the curved block 75 resets simultaneously. Therefore, during the process of multiple guide rods 32 sequentially contacting the curved block 75, the curved block 75 can perform vertical reciprocating movement. When the curved block 75 reciprocates vertically, it can drive the two slides 71 to reciprocate along the bottom slope of the ultrasonic cleaning box 1 via two connecting rods 76. The two curved blocks 75 have the same function, making the movement of the slides 71 more stable. When the slides 71 reciprocate, they drive the multiple shovels 72 above them to reciprocate. The shovels 72 can rotate. When the shovels 72 move towards the water outlet pipe, the bottom of the shovels 72 rests on the slope, and the shovels 72 are in an inclined state, thereby shoveling the impurities on the slope towards the water outlet pipe. In this state, the fins 73 on the shovels 72 are in a vertical state. When the shovels 72 move towards the water outlet pipe, the fins 73 on the shovels 72 are in a vertical state. When moving away from the outlet pipe, the resistance of the cleaning fluid on the fins 73 causes the shovel 72 to swing upward, causing the bottom of the shovel 72 to detach from the slope. This prevents impurities on the slope from being carried away from the outlet pipe. Therefore, when impurities in the ultrasonic cleaning box 1 are deposited at the bottom, the reciprocating movement of multiple shovels 72 causes the shovels 72 to shovel the impurities deposited on the slope towards the outlet pipe, causing the impurities to accumulate at the outlet pipe. This makes it easier for most of the impurities to be discharged through the outlet pipe during drainage, reducing the amount of impurities remaining inside the ultrasonic cleaning box 1 during drainage, and thus shortening the subsequent cleaning time of the ultrasonic cleaning box 1.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
