Description

Technical Field

[0001] This utility model relates to the technical field of workpiece cleaning equipment, specifically to an ultrasonic cleaning machine. Background Technology

[0002] An ultrasonic cleaner is a device that uses high-frequency ultrasonic waves (typically 20kHz–1MHz) to generate cavitation effects in a liquid, thereby efficiently cleaning, dispersing, emulsifying, or mixing the surface of a workpiece. Its core principle is that ultrasonic vibrations create microbubbles in the liquid. These bubbles rapidly expand and burst under alternating high and low pressure, generating strong impact forces and microjets, thus removing dirt or dispersing particles.

[0003] However, existing ultrasonic cleaners suffer from uneven ultrasonic wave distribution during use, which can easily create "hot spots" (areas with strong cavitation effects) in fixed locations, while other areas have weaker cleaning effects. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultrasonic cleaning machine to solve the problem that the uneven distribution of ultrasonic waves in the ultrasonic cleaning machine leads to poor cleaning effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic cleaner, comprising an ultrasonic cleaner body and a water circulation assembly disposed within the ultrasonic cleaner body. The water circulation assembly comprises a plurality of water circulation structures spaced apart along the width direction within the ultrasonic cleaner body. Each water circulation structure comprises two water flow driving parts correspondingly arranged on two inner walls facing each other along the length direction within the ultrasonic cleaner body. The two water flow driving parts cooperate to make the water within the ultrasonic cleaner body flow in a ring.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] This ultrasonic cleaner utilizes multiple water circulation structures within its main body to create flowing water that disperses cavitation bubbles, resulting in a more even distribution and reducing "dead zones" (areas with poor cleaning performance), thus improving overall cleaning efficiency. Specifically, two water flow drive units in each circulation structure work together to create a circular flow of water within the machine, ensuring uniform distribution of ultrasonic waves and enhancing the cleaning effect on the workpiece.

Detailed Implementation

[0014] The present invention will be further described in detail below through specific embodiments:

[0015] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown in the figure, this utility model embodiment proposes an ultrasonic cleaner, including an ultrasonic cleaner body 1 and a water circulation component 2 disposed within the ultrasonic cleaner body 1. The water circulation component 2 includes a plurality of water circulation structures spaced apart along the width direction within the ultrasonic cleaner body 1. Each water circulation structure includes two water flow driving parts correspondingly arranged on two inner walls arranged facing each other along the length direction within the ultrasonic cleaner body 1. The two water flow driving parts cooperate to make the water within the ultrasonic cleaner body 1 flow in a ring.

[0016] This ultrasonic cleaner utilizes multiple water circulation structures within the machine body 1 to create flowing water during operation. This disperses and distributes cavitation bubbles more evenly, reducing "dead zones" (areas with poor cleaning performance) and improving overall cleaning efficiency. Specifically, two water flow drive units in each circulation structure work together to create a circular flow of water within the machine body 1, ensuring uniform distribution of ultrasonic waves and enhancing the cleaning effect on the workpiece.

[0017] In this embodiment, there are two water circulation structures, which work together to ensure that the ultrasonic waves are evenly distributed within the ultrasonic cleaner body 1; therefore, there are also two water flow drive units provided on the same inner wall.

[0018] It should be noted that the ultrasonic cleaning machine body 1 is an existing structure that can generate ultrasonic waves in the water inside to clean the oil stains adhering to the surface of the workpiece.

[0019] To better understand this solution, the following section will optimize the structure of the water flow drive unit and other components.

[0020] like Figure 2 , Figure 3 as well as Figure 4 As shown, according to another embodiment of the present invention, an ultrasonic cleaner includes a water flow driving unit comprising a first water guide cylinder 21 and a first circulation pump 22. The first water guide cylinder 21 is fixedly mounted on the corresponding inner wall and arranged along the height of the ultrasonic cleaner body 1. A plurality of first liquid guiding holes 23 communicating with the interior are spaced along the length of the side wall of the first water guide cylinder 21. The first circulation pump 22 is located on the inner bottom side of the first water guide cylinder 21, and its inlet communicates with the interior of the first water guide cylinder 21. Its outlet pipe extends horizontally to... The first water guide tube 21 is externally connected to the inside of the ultrasonic cleaner body 1; the other water flow driving part includes a second water guide tube and a second circulation pump. The second water guide tube is fixedly installed on the corresponding inner wall and arranged along the height of the ultrasonic cleaner body 1. A number of second liquid guide holes communicating with the inside are arranged at intervals along the length direction on the side wall of the second water guide tube. The second circulation pump is located on the bottom side of the second water guide tube and its outlet is connected to the inside of the second water guide tube. Its inlet pipe extends horizontally to the outside of the second water guide tube and communicates with the inside of the ultrasonic cleaner body 1.

[0021] In this embodiment, the structures of the two water flow drive units are basically the same, except that the installation methods of the circulation pumps are different. The first circulation pump 22 of one water flow drive unit operates, drawing water from the upper side of the ultrasonic cleaner body 1 through several first liquid guide holes 23 into the first water guide cylinder 21, and then guiding it horizontally from the outlet pipe of the first circulation pump 22 to the bottom side of the ultrasonic cleaner body 1. At the same time, the second circulation pump of the other water flow drive unit also operates, and water from the bottom side of the ultrasonic cleaner body 1 enters the inlet pipe of the second circulation pump horizontally, then enters the second water guide cylinder, and is guided horizontally through several second liquid guide holes to the upper bottom side of the ultrasonic cleaner body 1. This causes the water in the ultrasonic cleaner body 1 to flow in a ring, which disperses the cavitation bubbles gathered in the ultrasonic cleaner body 1, making them more evenly distributed, reducing "dead zones", and improving the overall cleaning efficiency.

[0022] The tops of the first water guide tube 21 and the second water guide tube are also connected to each other, thereby increasing the number of water inlet channels of the first water guide tube 21 and the number of water outlet channels of the second water guide tube, and further improving the water circulation capacity within the ultrasonic cleaner body 1.

[0023] To protect the water flow drive unit and reduce or prevent impurities from entering it; such as Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the ultrasonic cleaner body 1 is divided into three cavities from left to right by two filter plates 3. The water flow driving parts arranged on the inner wall of one cavity are all located in the leftmost cavity, and the water flow driving parts arranged on the inner wall of the other cavity are all located in the rightmost cavity.

[0024] In this embodiment, the two filter plates 3 divide the ultrasonic cleaner body 1 into three cavities. The middle cavity is larger and is used to place the workpiece for cleaning. The cavities on both sides are smaller and are used to arrange the two water flow drive units so that the workpiece and the water flow drive units do not interfere with each other. At the same time, the two filter plates 3 cooperate with the two water flow drive units to filter the circulating water, preventing impurities from entering the water flow drive units and affecting their normal operation.

[0025] The leftmost cavity and the rightmost cavity are each detachably connected to a sealing plate 4 at their top. The sealing plate 4 further creates a relatively sealed environment for the leftmost cavity and the rightmost cavity, providing better protection. Specifically, the sealing plate 4 is connected to the corresponding filter screen 3 by screws, which facilitates the installation or removal of the sealing plate 4.

[0026] To further improve the cleaning effect of the workpiece, such as Figure 1 , Figure 2 as well as Figure 5 As shown, according to another embodiment of the present invention, an ultrasonic cleaning machine is provided, wherein the ultrasonic cleaning machine body 1 is equipped with a workpiece placement assembly 5. The workpiece placement assembly 5 includes a support 51, a workpiece placement cage 52, a connecting frame 53, and a telescopic driver 54. The support 51 is fixedly connected to the ultrasonic cleaning machine body 1; the workpiece placement cage 52 is used to hold the workpiece to be cleaned; the connecting frame 53 is rotatably connected to the workpiece placement cage 52 and is provided with a rotary driver 55 for driving the workpiece placement cage 52 to rotate; the telescopic driver 54 is connected between the connecting frame 53 and the support 51 and is used for telescopic adjustment to move the connecting frame 53 into or out of the ultrasonic cleaning machine body 1.

[0027] In this embodiment, the bracket 51 is inverted "U" shape and is located above the ultrasonic cleaner body 1. Both ends of the bracket 51 extend downwards and are fixedly connected to the outer wall of the ultrasonic cleaner body 1, serving as the main support frame. To improve the connection strength between the bracket 51 and the ultrasonic cleaner body 1, crossbeams fixed to the outer wall of the ultrasonic cleaner body 1 are connected to both ends of the bracket 51. The connecting frame 53 is also inverted "U" shape, with the workpiece placement cage 52 rotatably connected to the bottom side of the connecting frame 53, and part of the workpiece placement cage 52 placed inside the connecting frame 53. There are two telescopic actuators 54, both of which can be electric telescopic rods. The two electric telescopic rods extend and retract synchronously to move the workpiece placement cage 52 into the underwater section of the ultrasonic cleaner body 1 or to move the workpiece placement cage 52 out of the ultrasonic cleaner body 1. The rotary actuator 55 can be a motor. During the process of moving the workpiece placement cage 52 containing the workpiece into the ultrasonic cleaner body 1 for cleaning, the rotary actuator 55 drives the workpiece placement cage 52 to rotate at a certain angle every once in a while, so as to flip the workpiece in the workpiece placement cage 52, which helps to improve the cleaning effect of the workpiece.

[0028] Furthermore, the workpiece placement cage 52 includes an end plate 521, a connecting strip 522, and a sealing mesh plate 523. There are two end plates 521 arranged facing each other. Both end plates 521 are rotatably connected to the connecting frame 53. One of the end plates 521 is connected to the rotary driver 55.

[0029] The connecting strips 522 are multiple and connected between the two end plates 521 to form a cage-like structure with an opening; the sealing mesh plate 523 is detachably connected to the opening of the cage-like structure.

[0030] Here, the workpiece placement cage 52 is composed of an end plate 521, a connecting strip 522, and a sealing mesh plate 523, possessing sufficient structural strength. When the workpiece placement cage 52 is placed inside the ultrasonic cleaner body 1, water from the ultrasonic cleaner body 1 can enter the workpiece placement cage 52 to clean the workpiece. Opening the sealing mesh plate 523 facilitates placing or removing the workpiece from the cage structure; closing the sealing mesh plate 523 prevents the workpiece from detaching from the workpiece placement cage 52. In this embodiment, the sealing mesh plate 523 is square, with overlapping blocks connected to its four corners. After the sealing mesh plate 523 is embedded in the opening of the cage structure, the four overlapping blocks overlap the corresponding end plates 521 and are then connected by screws or other existing locking structures.

[0031] When using this ultrasonic cleaner:

[0032] Open the sealing mesh plate 523, place the workpiece into the cage structure, and then close the sealing mesh plate 523;

[0033] Start the two telescopic actuators 54. The two telescopic actuators 54 extend to insert the workpiece placement cage 52 into the underwater section of the ultrasonic cleaner body 1 and then stop operating.

[0034] The ultrasonic cleaner body 1 and all circulation pumps are driven, and the workpiece is cleaned inside the ultrasonic cleaner body 1.

[0035] During the cleaning process, the rotary drive 55 is activated every once in a while, and the workpiece placement cage 52 rotates at a certain angle;

[0036] After the staff observes that the workpiece is clean, they turn off the ultrasonic cleaner body 1 and all circulation pumps, and then start the two telescopic actuators 54 again. The two telescopic actuators 54 retract to move the workpiece placement cage 52 out of the ultrasonic cleaner body 1 to the initial position and then turn it off.

[0037] Open the sealing mesh plate 523 and remove the workpiece from the cage structure.

[0038] It should be noted that: all electrical components in this solution are connected by wires and arranged in a reasonable manner, which is the existing method and is not shown in the attached drawings; and the start and stop of each motor component can be controlled by a switch, which is also not shown in the attached drawings.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
