[0002] Ultrasonic cleaning machines use ultrasonic waves to clean materials. Because of its "cavitation" effect, it can quickly peel off the attachments on the surface of objects, so it is widely used in device cleaning in manufacturing, medical, service and other industries.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In the description of the present application, if there are reference terms such as "one embodiment", "some embodiments", "an embodiment", "some examples", "some embodiments", "illustrative embodiments", "examples", "specific examples", "some examples", etc., it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0031] The present application relates to an ultrasonic cleaning machine, which includes an ultrasonic cleaning component 1000. The ultrasonic cleaning component 1000 is filled with a cleaning liquid and cleans materials in an ultrasonic manner.

[0032] The ultrasonic cleaning assembly 1000 includes an ultrasonic barrel, which includes a barrel body 1100 and a transducer 1200. The bottom of the barrel body 1100 can drain water, and the transducer 1200 is provided in a plurality, and the transducer 1200 is provided on the outer side wall of the barrel body 1100. The side wall of the barrel body 1100 is a circular side wall, and the diameter of the side wall of the barrel body 1100 gradually decreases from the top to the bottom. The side wall of the barrel body 1100 is large at the top and small at the bottom, forming a shape with an open top and a gradually reduced bottom.

[0033] Furthermore, the side wall of the barrel body 1100 is divided into N side wall units 1101, where N is an integer and greater than 1. There is an angle between two adjacent layers of side wall units 1101, the diameter of the side wall units 1101 is larger at the top and smaller at the bottom, and the side wall units 1101 of the next layer are inclined relative to the side wall units 1101 of the previous layer.

[0034] Specifically, from top to bottom, the side wall units 1101 are gradually inclined toward the central axis of the barrel body 1100, thereby forming a cylindrical side wall with a gradually decreasing diameter. It can be understood that a plurality of transducers 1200 are arranged on the outer side of the side wall unit 1101, and the transducers 1200 are arranged circumferentially.

[0035] The angle between two adjacent layers of side wall units 1101 is A, which satisfies: 135°<A<180°. The center lines of the transducers 1200 of each layer of side wall units 1101 can converge at the center point of the top of the barrel body 1100, so that the ultrasonic waves of each transducer 1200 can converge at the center point of the top of the barrel body 1100, thereby converging the energy of the ultrasonic wave. The barrel body 1100 generates more dense tiny vacuum bubbles in the center area than ordinary ultrasonic cleaning machines, and cleans the surface of the material with the instantaneous shock wave and instantaneous high pressure generated when the bubbles burst, thereby improving the cleaning efficiency.

[0036] It should be noted that, in order to ensure that the ultrasonic waves of the transducers 1200 of each layer of the side wall units 1101 can be gathered at the center point of the top of the barrel body 1100, the angles A of the side wall units 1101 of each adjacent layer can be the same or different. It is understandable that the barrel body 1100 is designed to be a shape with a gradually decreasing diameter in order to ensure that the ultrasonic waves of the transducers 1200 of each layer can be gathered at the center point.

[0037] On the other hand, the range of the design angle A can control the size of the ultrasonic barrel. If A is less than 135°, the size of the ultrasonic barrel is too small to meet the use requirements.

[0038] In some embodiments, on the side wall of the barrel body 1100 , the first layer of side wall units 1101 located at the top and the Nth layer of side wall units 1101 located at the bottom are perpendicular to each other.

[0039] As the side wall units 1101 from the second layer to the N-1 layer are tilted layer by layer, the wall surface of the side wall of the barrel body 1100 gradually changes from the vertical wall surface of the first layer of side wall units 1101 to the horizontal wall surface of the Nth layer of side wall units 1101.

[0040] The side wall of the barrel body is gradually inclined at an angle to achieve perpendicularity between the first layer side wall unit 1101 and the Nth layer side wall unit 1101, which has at least the following beneficial effects: ensuring that the ultrasonic waves of the transducers on each side wall unit 1101 converge at a point in the top center to enhance the ultrasonic energy; ensuring that dirt converges at the bottom of the ultrasonic barrel; and facilitating water control and structural manufacturing.

[0041] It is understandable that if the ultrasonic energy can be focused at one point and the dirt can be collected at the bottom for discharge, the first layer side wall unit 1101 and the Nth layer side wall unit 1101 can also be set to be not perpendicular but at an inclined angle. The angle B between the first layer side wall unit 1101 and the Nth layer side wall unit 1101 ranges from 90° to 180°.

[0042] In some examples, the cross section of the side wall unit 1101 is a straight line profile, and the inclined side wall unit 1101 in the barrel body 1100 is formed as a tapered side wall. In this case, the tapered angle of the tapered side wall of the side wall unit 1101 of the next layer is smaller than the tapered angle of the tapered side wall of the side wall unit 1101 of the previous layer.

[0043] It should be noted that, when the first layer sidewall unit 1101 is a vertical wall surface and the Nth layer sidewall unit 1101 is a horizontal wall surface, the middle second layer to the N-1th layer sidewall unit 1101 are formed as tapered side walls.

[0044] In some examples, the cross-section of the side wall unit 1101 is an arc-shaped profile, and the side wall unit 1101 of the barrel body 1100 is formed as a C-shaped wall surface.

[0045] In this case, the top of the wall surface of the first layer of side wall units 1101 has a vertical tangent line, and from top to bottom, the tangent lines of the top of the wall surfaces of each layer of side wall units 1101 gradually tilt, thereby forming a barrel body 1100 that is larger at the top and smaller at the bottom. It should be noted that the angle between the tangent lines of two adjacent layers of side wall units 1101 is regarded as the angle A between the two adjacent layers of side wall units 1101.

[0046] In some examples, the side wall of the barrel body 1100 is a spherical wall surface. Further, the barrel body 1100 is set to a hemispherical shape.

[0047] It should be noted that the first layer side wall unit 1101 in the barrel body 1100 can also be designed as an inclined wall surface instead of a vertical wall surface, and the Nth layer side wall unit 1101 in the barrel body 1100 can also be designed as an inclined wall surface instead of a horizontal wall surface.

[0048] In some implementations, the distance between the upper and lower ends of the side wall unit 1101 is defined as width L, and from top to bottom, the width of the side wall units 1101 from the first layer to the N-1th layer is defined as width L1, and the width of the side wall unit 1101 of the Nth layer is defined as width L2, satisfying: L1<L2<2*L1.

[0049] If L2 is too large, the ultrasonic center point will be significantly offset. On the other hand, L2 will be too large and will exceed the range of the transducer to transmit the sound wave energy. If L2 is too small, the transducer will interfere with the drainage at the bottom of the barrel body 1100, and L2 will be too small and the transducer cannot be installed.

[0050] It can be understood that, in order to ensure that the ultrasonic waves of the transducers 1200 of each layer can be converged at the center point, the widths L1 of the side wall units 1101 from the first layer to the N-1th layer may be the same or different.

[0051] In some implementations, the diameter of the transducer 1200 is D, satisfying: L≥1.5*D.

[0052] Specifically, L1≥1.5*D, and accordingly, L2≥1.5*D. In this case, interference between the transducers of two adjacent layers of side wall units can be avoided during installation. On the other hand, if L is too small, the size of the cleaning tank is too small, which is not conducive to the placement of products.

[0053] In some embodiments, the frequencies of adjacent transducers 1200 are different from the top to the bottom of the outer wall of the barrel body 1100. Arranging the transducers in a staggered frequency manner enables transducers of different frequencies to clean different types of dirt, avoiding energy waste and frequency superposition.

[0054] It should be noted that if adjacent transducers have the same frequency, the cleaning effects of the two adjacent transducers with the same frequency will overlap, resulting in energy waste. On the other hand, the energy superposition of transducers with the same frequency leads to excessive ultrasonic energy, which can easily damage the product. However, if only one of the two adjacent transducers is turned on, it will cause a waste of space.

[0055] In some embodiments, on the outer side wall of the barrel body 1100, two adjacent transducers 1200 on the same layer of side wall units 1101 have different frequencies. Arranging transducers in a staggered frequency manner enables transducers of different frequencies to clean different types of dirt, avoiding energy waste and frequency superposition.

[0056] In some implementations, among the transducers 1200 of the first layer sidewall unit 1101 , the angle between the distribution intervals of the transducers 1200 with the same frequency does not exceed 20°.

[0057] It is understandable that the ultrasonic energy radiation range of the transducer 1200 is 22.5° from the center of the transducer to the surrounding area. Therefore, if the angle between the distribution intervals of the transducers 1200 of the same frequency is greater than 20°, it is very likely to cause the ultrasonic energy to weaken and reduce the cleaning effect.

[0058] In some embodiments, the ultrasonic barrel includes a cylindrical barrel body 1300, which is connected to the top of the barrel body 1100, and the cylindrical barrel body 1300 is arranged coaxially with the barrel body 1100, and the diameter of the cylindrical barrel body 1300 is the same as the diameter of the top of the first layer side wall unit 1101.

[0059] Furthermore, an observation window is provided on the side wall of the cylindrical barrel 1300 so that the user can observe the internal conditions of the ultrasonic barrel. The observation window is made of a transparent material.

[0060] In some embodiments, the ultrasonic cleaning machine includes a water collecting tank 2000. After cleaning, the ultrasonic cleaning assembly 1000 discharges the cleaning liquid into the water collecting tank 2000. A drain pipe is provided at the bottom of the ultrasonic barrel, specifically, the drain pipe is provided at the bottom of the barrel body 1100, and the drain pipe extends to the water collecting tank 2000.

[0061] It is understandable that the ultrasonic barrel discharges the cleaning liquid to the water collecting tank 2000 through the drain pipe. Further, the drain pipe is provided with a valve to realize the on-off of the drain pipe, thereby controlling the drainage.

[0062] Furthermore, the water collecting tank 2000 has a filtering function so as to recycle the cleaning liquid, and filtering impurities can also prevent the cleaning liquid from clogging the pipeline.

[0063] Specifically, the water collecting tank 2000 includes a first filter structure 2101, which is disposed at the inlet of the water collecting tank 2000. The cleaning liquid discharged by the ultrasonic cleaning assembly 1000 enters the water collecting tank 2000 after passing through the first filter structure 2101. The cleaning liquid is processed and recovered in the water collecting tank 2000 for recycling.

[0064] In some examples, the inlet of the water collecting tank 2000 is arranged at the top, and the first filtering structure 2101 is arranged at the top of the water collecting tank 2000. Further, the top of the water collecting tank 2000 is arranged to be open, and the lower end of the drain pipe extends to the top of the water collecting tank 2000.

[0065] Specifically, the first filtering structure 2101 is configured as a mesh frame, a filter screen, or a sponge.

[0066] In some examples, the first filtering structure 2101 is composed of a plurality of long rods forming a grid, and the plurality of long rods form spaced apart spaces. Further, the long rods are arranged in parallel or in a longitudinal and transverse arrangement.

[0067] In some examples, the water collecting tank 2000 includes a first box body 2201, the lower end of the drain pipe extends to the inlet of the first box body 2201, and the first filter structure 2101 is disposed in the first box body 2201. Specifically, the top of the first box body 2201 is open, and the first filter structure 2101 is placed flat on the top of the first box body 2201.

[0068] In some examples, the water collecting tank 2000 includes a second tank body 2202, the first tank body 2201 is connected to the second tank body 2202, the treated cleaning liquid in the first tank body 2201 flows into the second tank body 2202, and the reflux component 3000 transports the cleaning liquid in the second tank body 2202 to the ultrasonic barrel.

[0069] Furthermore, a second filter structure 2102 is disposed in the second box 2202, the inlet of the reflux pipe 3100 is located in the second box 2202, and the second filter structure 2102 further purifies the cleaning liquid. Specifically, the second filter structure 2102 is configured as a filter screen.

[0070] In some examples, the second box 2202 and the first box 2201 are arranged side by side, and the cleaning liquid is filtered in the first box 2201 and then allowed to settle before entering the second box 2202 .

[0071] Specifically, a partition 2300 is provided in the water collecting tank 2000, and the partition 2300 is arranged vertically. The partition 2300 divides the chamber of the water collecting tank 2000 into a first box body 2201 and a second box body 2202 arranged side by side, and the cleaning liquid in the first box body 2201 overflows from the top of the partition 2300 to the second box body 2202. Further, the second filtering structure 2102 is arranged vertically in the second box body 2202, thereby dividing the chamber of the second box body 2202 into two parts, so as to filter the cleaning liquid entering the second box body 2202.

[0072] Regarding the arrangement of the second filtering structure 2102 and the partition 2300 , at least an alternative design is possible: in the water collecting tank 2000 , the second box body 2202 and the first box body 2201 are separated by the second filtering structure 2102 .

[0073] Regarding the arrangement of the first box body 2201 and the second box body 2202, at least an alternative design is possible: the first box body 2201 and the second box body 2202 are arranged in layers, the first box body 2201 is located on the upper side of the second box body 2202, and the second filtering structure 2102 is placed flat and located between the second box body 2202 and the first box body 2201.

[0074] In some embodiments, the ultrasonic cleaning assembly 1000 includes an overflow assembly, which is disposed on a side wall of the ultrasonic barrel, and the cleaning liquid in the ultrasonic barrel can overflow from the overflow assembly to the water collecting tank 2000 .

[0075] Further, the overflow assembly is arranged on the side wall of the cylindrical barrel 1300. Specifically, the overflow assembly includes an overflow pipe 1401, the upper end of the overflow pipe 1401 is connected to the interior of the ultrasonic barrel, and the lower end of the overflow pipe 1401 extends to the water collecting tank 2000. It can be understood that the upper end of the overflow pipe 1401 is arranged on the side wall of the cylindrical barrel 1300.

[0076] In some embodiments, the ultrasonic cleaning machine includes a reflux assembly 3000, which is used to return the cleaning liquid in the water collecting tank 2000 to the ultrasonic cleaning assembly 1000 to achieve recycling of the cleaning liquid.

[0077] Specifically, the reflux assembly 3000 includes a reflux pipe 3100, which extends to the water collecting tank 2000. The reflux assembly 3000 returns the purified cleaning liquid in the water collecting tank 2000 to the ultrasonic cleaning assembly 1000 through the reflux pipe 3100. Further, the reflux pipe 3100 is arranged vertically, and the lower end of the reflux pipe 3100 extends to the second box body 2202.

[0078] It can be understood that the reflux component 3000 includes a reflux pump, which is connected to the reflux pipe 3100 and provides power for the reflux of the cleaning liquid.

[0079] In some examples, the reflux assembly 3000 includes a heater connected to the reflux pipe 3100. The heater is used to heat the refluxed cleaning fluid to a set temperature, thereby improving the cleaning fluid's ability to dissolve dirt.

[0080] Furthermore, the heater is configured as an electric heater.

[0081] In some embodiments, the reflux assembly 3000 includes a spray assembly, which is connected to the reflux pipe 3100. The spray assembly is located on the upper side of the ultrasonic barrel, and the cleaning liquid flows back into the ultrasonic barrel in a spraying manner.

[0082] In this case, the sprayed cleaning liquid can destroy the static liquid surface in the ultrasonic barrel, causing the nodes and amplitude of the ultrasonic wave to change with the change of the liquid surface, that is, the strongest position of the sound wave changes with the change of the liquid surface, thereby cleaning the material more evenly and avoiding the existence of cleaning dead corners.

[0083] In some examples, the spray assembly includes a water outlet chamber 3201 , the water outlet chamber 3201 is connected to the return pipe 3100 , and a plurality of water outlet holes are disposed at the bottom of the water outlet chamber 3201 .

[0084] Furthermore, the water outlet chamber 3201 is circular, and the diameter of the water outlet chamber 3201 is consistent with the diameter of the opening at the top of the ultrasonic barrel body or is slightly smaller than the diameter of the opening at the top of the ultrasonic barrel body, so that the water outlet chamber 3201 can cover the entrance of the ultrasonic barrel body to avoid water splashing.

[0085] In some examples, the water outlet chamber 3201 is configured as a shower head.

[0086] In some examples, the spray assembly is hinged to the return pipe 3100 so as to move the water outlet chamber 3201 away from the upper side of the ultrasonic barrel, making it easier for the user to put materials into the ultrasonic barrel. Specifically, the spray assembly includes a connecting pipe 3202, one end of which is connected to the water outlet chamber 3201, and the other end of which is hinged to the return pipe 3100.

[0087] In some embodiments, the ultrasonic cleaning machine includes a third filtering structure, and the cleaning liquid of the reflux component 3000 enters the ultrasonic cleaning component 1000 through the third filtering structure.

[0088] Specifically, the third filter structure is located between the ultrasonic barrel and the spray assembly. Alternatively, the third filter structure is located in the cylindrical barrel 1300.

[0089] In some examples, the third filtering structure is configured as a filter.

[0090] In some embodiments, the ultrasonic cleaning machine includes a housing, and the ultrasonic cleaning assembly 1000 and the reflux assembly 3000 are both disposed in the housing. Further, the water collecting tank 2000 is disposed in the housing.

[0091] The inner wall of the box body is provided with a sound insulation structure to reduce the noise of the ultrasonic cleaning machine. Specifically, the sound insulation structure is provided with sound insulation cotton.

[0092] It should be noted that the ultrasonic cleaning machine has at least the following working modes:

[0093] The first type is that during the cleaning process, the cleaning liquid in the ultrasonic barrel is in a state of running water flow, with water entering from the top of the ultrasonic barrel and exiting from the bottom to ensure that the cleaning liquid is always clean. In this case, the ultrasonic cleaning machine may or may not be equipped with a water collection tank and a reflux component.

[0094] The second type is that during the cleaning process, the cleaning liquid in the ultrasonic barrel is in a circulating flow state, and the cleaning liquid in the ultrasonic barrel is discharged from the bottom to the water collecting tank. The reflux component returns the cleaning liquid in the water collecting tank to the ultrasonic barrel, and the cleaning and circulating flow are carried out simultaneously.

[0095] The third type is that after cleaning is completed, the cleaning liquid in the ultrasonic barrel is discharged into the water collection tank. In this case, the ultrasonic cleaning machine may or may not be equipped with a reflux component.

[0096] Fourthly, after the cleaning is completed, the cleaning liquid in the ultrasonic barrel is discharged into the water collecting tank, and the reflux component returns the cleaning liquid in the water collecting tank to the ultrasonic barrel.

[0097] The above is a detailed description of the implementation methods of the present application in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods.
