Description

Technical Field

[0001] The invention relates to the technical field of cleaning machines, in particular to a split-type ultrasonic cleaning machine. Background Art

[0002] Ultrasonic cleaning technology is an advanced technique for efficiently cleaning surfaces based on the physical effects of ultrasound waves propagating through liquids, including cavitation, straight-through flow, and acceleration. Cavitation is one of the most critical mechanisms in the ultrasonic cleaning process. When ultrasound waves propagate through a liquid, they create alternating regions of density within the liquid. In negative pressure regions, the distance between liquid molecules increases. When the tension exceeds the cohesive force of the liquid, the molecules break apart, forming tiny cavitation bubbles. These cavitation bubbles quickly close in positive pressure regions, generating localized high temperature, high pressure, and intense shock waves, which remove dirt from the surface.

[0003] In existing split-type ultrasonic cleaning machines, the ultrasonic transducer is typically mounted directly on the bottom or side of the cleaning tank. The ultrasonic waves generated by them have a relatively simple propagation path and pattern within the liquid. As they propagate, the ultrasonic wave gradually attenuates with increasing distance, resulting in reduced ultrasonic intensity in areas far from the transducer. This limits the generation and collapse of cavitation bubbles, shortening the duration of cavitation.

[0004] Furthermore, the relatively slow flow of liquid within the cleaning tank limits the residence time of cavitation bubbles, making it difficult for them to fully exert their cleaning effect. When cavitation bubbles rise rapidly and burst, the resulting shock waves and high-temperature, high-pressure environment are unable to fully impact the surface, reducing cleaning effectiveness.

[0005] Existing split-type ultrasonic cleaning machines lack an effective turbulence-generating mechanism. Liquid flows within the cleaning tank primarily through natural convection, resulting in slow flow and a monotonous flow pattern, making it difficult to create strong localized turbulence on the surface. This lack of localized turbulence results in a low relative velocity between the liquid and the surface, hindering the removal and diffusion of dirt.

[0006] At the same time, due to the lack of turbulent stirring, the cleaning agent and dirt particles in the cleaning liquid are difficult to be evenly distributed, resulting in uneven cleaning effect and possible cleaning dead corners in some areas. Summary of the Invention

[0007] The object of the present invention is to provide a split-type ultrasonic cleaning machine to solve the problems raised in the prior art.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] The split-type ultrasonic cleaning machine includes an outer shell, a generating unit, a driving unit, an inner layer unit and an outer layer unit. The outer shell is placed on a horizontal ground. The generating unit is fixedly connected to the outer shell. The driving unit is fixedly connected to the outer shell. The inner layer unit is used to drive the outer layer unit to start. The inner layer unit is fixedly connected to the outer layer unit. The inner layer unit is movably connected to the generating unit. The outer layer unit is fixedly connected to the generating unit. The outer layer unit has the function of forming turbulence.

[0010] The outer shell is used to install and fix the generating unit, driving unit, inner unit and outer unit. The generating unit is used to generate ultrasonic waves, the driving unit is used to start the inner unit to form a spiral flow of liquid, and the outer unit is used to form turbulent liquid on the outside. After the items to be cleaned are placed, ultrasonic waves are generated by the generating unit for cleaning. The driving unit controls the start-up of the inner unit to form a spiral flow of the internal cleaning liquid, and the outer unit is used to form a turbulent disturbance of the cleaning liquid on the outside. The strong mixing characteristics of turbulence and the directional flushing ability of spiral flow are used to break through the limitations of the single cavitation effect of traditional ultrasonic cleaning and significantly improve the cleaning efficiency of complex items.

[0011] Furthermore, the generating unit includes an ultrasonic generator, a transducer, a partition, a cleaning basket, a mounting ring and a fixing column. The ultrasonic generator is fixedly installed at the bottom of the shell, the transducer is fixedly installed above the partition, the partition is fixedly installed in the shell on the side close to the horizontal ground, the bottom of the cleaning basket is in contact with the upper surface of the partition, a fixing column is provided on the cleaning basket, the cleaning basket is clamped on the mounting ring through the fixing column, the mounting ring is fixedly installed in the shell on the side away from the horizontal ground, the cleaning basket is movably connected to the inner layer unit, and the cleaning basket is fixedly connected to the outer layer unit.

[0012] When the items to be cleaned are placed in the cleaning basket, the user closes the lid, and the controller controls the electric telescopic rod to extend and engage with the inner gear ring. The power switch is pressed, and the ultrasonic generator starts and transmits an electrical signal to the transducer, which converts the electrical signal into high-frequency sound wave vibration, producing a cavitation effect in the cleaning liquid. After bubbles are generated, the energy generated by the bubbles rising and bursting cleans the surface of the cleaning items, thereby completing the cleaning of the items.

[0013] Furthermore, the driving unit includes a driving motor, a driving elliptical gear, a driven elliptical gear, an inner ring gear and a thin film pressure sensor. The fixed end of the driving motor is fixedly mounted on the upper surface of the outer shell. The output shaft of the driving motor passes through the outer shell and is fixedly connected to the driving elliptical gear. The driving elliptical gear is meshed with the driven elliptical gear. The driven elliptical gear cooperates with the inner ring gear. The tooth surfaces at both ends of the long axis of the driven elliptical gear are provided with thin film pressure sensors. The inner ring gear is provided with a plurality of clamping holes at one end close to the horizontal ground. The driven elliptical gear is rotatably connected to the outer shell through a connecting rod. The inner ring gear is rotatably connected to the inner surface of the outer shell at one end away from the horizontal ground.

[0014] The controller controls the drive motor to start, thereby driving the active elliptical gear to rotate. During the rotation process, the active elliptical gear is always engaged with the driven elliptical gear, thereby driving the driven elliptical gear to rotate. When the active elliptical gear rotates to engage with both ends of the long axis of the driven elliptical gear, or when the teeth at both ends of the long axis of the driven elliptical gear are engaged with the inner gear ring, the film pressure sensor is subjected to pressure. At this time, the film pressure sensor feeds back the signal to the controller, and the controller transmits current to the memory spring. During the meshing rotation process of the driven elliptical gear and the inner gear ring, the inner gear ring is driven to rotate rapidly. When the inner gear ring is disengaged from the driven elliptical gear, the inner gear ring slowly reduces the rotation speed under the action of water flow resistance, thereby driving the ring plate to rotate under the transmission action of the electric telescopic rod, causing the ring plate to rotate rapidly, then slowly, and then rapidly.

[0015] Furthermore, the inner layer unit includes a ring plate, an electric telescopic rod, a round rod, a torsion spring and a telescopic grid. The ring plate is sleeved on the cleaning basket, the fixed end of the electric telescopic rod is fixedly mounted on the upper surface of the ring plate, the round rod is fixedly connected to the ring plate, one end of the torsion spring is fixedly connected to the round rod, and the other end of the torsion spring is fixedly connected to the fixed end of the telescopic grid. A plurality of groups of diamond holes are provided on the surface of the telescopic grid. The fixed end and the telescopic end of the telescopic grid are connected by a spring. The round rod is rotatably connected to the telescopic grid, and the ring plate is fixedly connected to the outer layer unit.

[0016] Furthermore, the inner layer unit also includes an arc box, a counterweight, a memory spring and a return spring. The arc box is fixedly installed on the lower surface of the fixed end of the telescopic grid, and the counterweight is slidably installed in the arc box. One end of the memory spring is fixedly connected to the counterweight, and the other end is fixedly connected to the inner wall of the arc box. The counterweight is fixedly connected to the telescopic end of the telescopic grid through a pull rope, one end of the return spring is fixedly connected to the ring plate, and the other end of the return spring is slidably connected to the bottom extension of the cleaning basket.

[0017] When the driven elliptical gear meshes with the inner gear ring, the thin film sensor feeds back a signal to the controller, and the controller transmits current to the memory spring. At this time, the memory spring contracts rapidly after receiving the current, thereby driving the counterweight to move outward along the arc box. On the one hand, the telescopic grid contracts under the action of the pull rope, and at the same time, the center of gravity of the telescopic grid changes. As a result, under the action of the counterweight, the telescopic grid compresses the torsion spring and deflects rapidly around the round rod, thereby stirring the cleaning liquid. Because the driven elliptical gear contacts the inner gear ring when it rotates, the inner gear ring rotates rapidly, thereby driving the ring plate to rotate rapidly, so that the telescopic grid is The rapid rotation causes the telescopic grid to produce periodic acceleration and deceleration motion, forming a pulsating water flow, enhancing the cavitation effect, and coordinating with the rapid flipping action of the telescopic grid, thereby forming a spiral shear flow of the cleaning liquid in the inner layer, effectively cleaning the items to be cleaned, and further improving the cleaning effect of the items. When the driven elliptical gear is disengaged from the inner ring gear, the film pressure sensor is no longer under pressure. At this time, the counterweight block slowly resets and flips to a horizontal state under the action of the memory spring and the restoring force of the torsion spring itself. At the same time, the telescopic grid re-extends to intercept and split the generated bubbles, increasing the time of the cavitation effect and further improving the cleaning effect.

[0018] Furthermore, the outer layer unit includes a rack, a gear, a cylinder, a bent rod and an impeller, the rack is fixedly connected to the ring plate, the rack is meshed with the gear, the gear is fixedly connected to the cylinder, the cylinder is rotatably connected to the bent rod, the bent rod is fixedly connected to the cleaning basket, and the cylinder is fixedly connected to the impeller.

[0019] When the counterweight moves to the outside of the telescopic grid, the return spring is squeezed to drive the ring plate downward, causing the rack to move downward while driving the gear to rotate rapidly on the bent rod, thereby driving the impeller to rotate under the transmission action of the cylinder, stirring the outer layer of cleaning liquid to form turbulence, and cooperating with the inner layer of spiral water flow to form a complex flow field, further improving the cleaning effect of the objects.

[0020] Furthermore, the contraction speed of the memory spring is greater than the extension speed.

[0021] In order to make the telescopic grid flip quickly to form a spiral flow field to clean the objects, the ring plate and the telescopic grid rotate from fast to slow and then to fast to form a pulsating water flow, thereby enhancing the cavitation effect. When the telescopic grid slowly returns to a horizontal state, the bubbles generated by the enhanced cavitation effect have a longer residence time or are split under the action of the telescopic grid, thereby further enhancing the cavitation effect and further improving the cleaning effect on the objects.

[0022] Furthermore, the initial position of the counterweight is located near one end of the center of the shell.

[0023] In order to facilitate the rapid contraction of the counterweight block, the telescopic grid is quickly deflected, so that the cleaning liquid forms a spiral flow field, thereby improving the cleaning effect on the objects.

[0024] Furthermore, the shell is composed of a housing and a cover, a controller is provided on the shell, and a power switch is provided on the shell.

[0025] To facilitate the user to start and stop the control device and receive and transmit controller signals.

[0026] Furthermore, the gear ratio of the driving elliptical gear to the driven elliptical gear is 1:6-1:3.

[0027] In order to transmit the rotation of the driving elliptical gear to the driven elliptical gear to form rapid rotation, different gear ratios can adapt to different torques and meet the cleaning power requirements under different liquid levels.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention controls the start of the driving motor through a controller, thereby driving the active elliptical gear to rotate. During the rotation process, the active elliptical gear is always engaged with the driven elliptical gear, thereby driving the driven elliptical gear to rotate. When the active elliptical gear rotates to engage with both ends of the long axis of the driven elliptical gear, or when the teeth at both ends of the long axis of the driven elliptical gear are engaged with the inner gear ring, the film pressure sensor is subjected to pressure. At this time, the film pressure sensor feeds back a signal to the controller, and the controller transmits current to the memory spring. During the meshing and rotation process of the driven elliptical gear and the inner gear ring, the inner gear ring is driven to rotate rapidly. When the inner gear ring is disengaged from the driven elliptical gear, the inner gear ring slowly reduces its rotation speed under the action of water flow resistance, thereby driving the ring plate to rotate under the transmission action of the electric telescopic rod, causing the ring plate to rotate rapidly, then slowly, and then rapidly.

[0030] 2. The present invention is that when the driven elliptical gear is meshed with the inner gear ring, the thin film sensor feeds back a signal to the controller, and the controller transmits current to the memory spring. At this time, the memory spring contracts rapidly after receiving the current, thereby driving the counterweight to move outward along the arc box. On the one hand, the telescopic grid contracts under the action of the pull rope. At the same time, due to the change in the center of gravity of the telescopic grid, the telescopic grid compresses the torsion spring under the action of the counterweight and deflects rapidly around the round rod, thereby stirring the cleaning liquid. Because the driven elliptical gear contacts the inner gear ring when it rotates, the inner gear ring rotates rapidly, thereby driving the ring plate to rotate rapidly, thereby causing the telescopic grid to The grid rotates rapidly, causing the telescopic grid to produce periodic acceleration and deceleration motion, forming a pulsating water flow, enhancing the cavitation effect, and coordinating with the rapid flipping action of the telescopic grid, so that the cleaning liquid in the inner layer forms a spiral shear flow, which effectively cleans the items to be cleaned, further improving the cleaning effect of the items. When the driven elliptical gear is disengaged from the inner ring gear, the film pressure sensor is no longer under pressure. At this time, the counterweight block slowly resets and flips to a horizontal state under the action of the restoring force of the memory spring and the torsion spring itself. At the same time, the telescopic grid re-extends to intercept and split the generated bubbles, thereby increasing the time of the cavitation effect and further improving the cleaning effect.

[0031] 3. The present invention drives the ring plate to move downward by squeezing the return spring when the counterweight moves to the outside of the telescopic grid, causing the rack to move downward and at the same time drive the gear to rotate rapidly on the bent rod, thereby driving the impeller to rotate under the transmission action of the cylinder, stirring the cleaning liquid in the outer layer to form turbulence, and cooperating with the spiral water flow in the inner layer to form a complex flow field, thereby further improving the cleaning effect on the objects.

[0032] 4. The present invention forms a composite flow field of outer turbulent disturbance and inner spiral shear in the cleaning basket through the synergistic effect of the outer layer units forming turbulence and the inner layer units forming spiral guides. By utilizing the strong mixing characteristics of turbulence and the directional flushing ability of spiral flow, it breaks through the limitation of the single cavitation effect of traditional ultrasonic cleaning and significantly improves the cleaning efficiency of complex workpieces.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example: Figures 1-11 As shown, the present invention provides a technical solution:

[0047] like Figure 1 、 Figure 3 As shown, a split ultrasonic cleaning machine includes an outer shell 1, a generating unit 2, a driving unit 3, an inner unit 4 and an outer unit 5. The outer shell 1 is placed on a horizontal ground, the generating unit 2 is fixedly connected to the outer shell 1, the driving unit 3 is fixedly connected to the outer shell 1, the inner unit 4 is used to drive the outer unit 5 to start, the inner unit 4 is fixedly connected to the outer unit 5, the inner unit 4 is movably connected to the generating unit 2, the outer unit 5 is fixedly connected to the generating unit 2, and the outer unit 5 has the function of forming turbulence.

[0048] The outer shell 1 is used to install and fix the generating unit 2, the driving unit 3, the inner layer unit 4 and the outer layer unit 5. The generating unit 2 is used to generate ultrasonic waves, the driving unit 3 is used to start the inner layer unit 4 to form a spiral flow of liquid, and the outer layer unit 5 is used to form turbulent liquid on the outside. After the items to be cleaned are placed, ultrasonic waves are generated by the generating unit 2 for cleaning, and the driving unit 3 controls the start of the inner layer unit 4 to form a spiral flow of the internal cleaning liquid, and the outer layer unit 5 is used to form a turbulent disturbance of the cleaning liquid on the outside. The strong mixing characteristics of the turbulent flow and the directional flushing ability of the spiral flow are utilized to break through the limitations of the single cavitation effect of traditional ultrasonic cleaning and significantly improve the cleaning efficiency of complex items.

[0049] like Figure 4 As shown, the generating unit 2 includes an ultrasonic generator 21, a transducer 22, a partition 23, a cleaning basket 24, a mounting ring 25 and a fixing column 26. The ultrasonic generator 21 is fixedly mounted on the bottom of the shell 1, the transducer 22 is fixedly mounted above the partition 23, the partition 23 is fixedly mounted on the side of the shell 1 close to the horizontal ground, the bottom of the cleaning basket 24 abuts against the upper surface of the partition 23, a fixing column 26 is provided on the cleaning basket 24, the cleaning basket 24 is clamped on the mounting ring 25 through the fixing column 26, and the mounting ring 25 is fixedly mounted on the side of the shell 1 away from the horizontal ground, the cleaning basket 24 is movably connected to the inner unit 4, and the cleaning basket 24 is fixedly connected to the outer unit 5.

[0050] After the items to be cleaned are placed in the cleaning basket 24, the user closes the cover 12, and the controller controls the electric telescopic rod 42 to extend and engage with the inner gear ring 34, and presses the power switch. At this time, the ultrasonic generator 21 is started and transmits an electrical signal to the transducer 22, which converts the electrical signal into high-frequency sound wave vibration, generating a cavitation effect in the cleaning liquid. After bubbles are generated, the energy generated by the bubbles rising and bursting cleans the surface of the cleaning items, thereby completing the cleaning of the items.

[0051] like Figure 3 、 Figure 5As shown, the drive unit 3 includes a drive motor 31, a driving elliptical gear 32, a driven elliptical gear 33, an inner ring gear 34 and a film pressure sensor 35. The fixed end of the drive motor 31 is fixedly mounted on the upper surface of the shell 1. The output shaft of the drive motor 31 passes through the shell 1 and is fixedly connected to the driving elliptical gear 32. The driving elliptical gear 32 is meshed with the driven elliptical gear 33. The driven elliptical gear 33 cooperates with the inner ring gear 34. The tooth surfaces at both ends of the long axis of the driven elliptical gear 33 are provided with film pressure sensors 35. The inner ring gear 34 is provided with a plurality of snap-in holes at one end close to the horizontal ground. The driven elliptical gear 33 is rotatably connected to the shell 1 through a connecting rod, and the inner ring gear 34 is rotatably connected to the inner surface of the end of the shell 1 away from the horizontal ground.

[0052] The controller controls the drive motor 31 to start, thereby driving the active elliptical gear 32 to rotate. During the rotation of the active elliptical gear 32, it is always engaged with the driven elliptical gear 33, thereby driving the driven elliptical gear 33 to rotate. When the active elliptical gear 32 rotates to engage with the two ends of the long axis of the driven elliptical gear 33, or when the teeth at both ends of the long axis of the driven elliptical gear 33 are engaged with the inner ring gear 34, the diaphragm pressure sensor 35 is subjected to pressure. At this time, the diaphragm pressure sensor 35 feeds back the signal to the controller, and the controller transmits current to the memory spring 48. During the meshing and rotation of the driven elliptical gear 33 and the inner ring gear 34, the inner ring gear 34 is driven to rotate rapidly. When the inner ring gear 34 is disengaged from the driven elliptical gear 33, the inner ring gear 34 slowly reduces the rotation speed under the action of water flow resistance, thereby driving the ring plate 41 to rotate under the transmission action of the electric telescopic rod 42, causing the ring plate 41 to rotate rapidly, then slowly, and then rapidly.

[0053] like Figure 6 、 Figure 7 As shown, the inner unit 4 includes a ring plate 41, an electric telescopic rod 42, a round rod 43, a torsion spring 44 and a telescopic grid 45. The ring plate 41 is sleeved on the cleaning basket 24. The fixed end of the electric telescopic rod 42 is fixedly mounted on the upper surface of the ring plate 41. The round rod 43 is fixedly connected to the ring plate 41. One end of the torsion spring 44 is fixedly connected to the round rod 43. The other end of the torsion spring 44 is fixedly connected to the fixed end of the telescopic grid 45. A plurality of groups of diamond holes are provided on the surface of the telescopic grid 45. The fixed end and the telescopic end of the telescopic grid 45 are connected by a spring. The round rod 43 is rotatably connected to the telescopic grid 45. The ring plate 41 is fixedly connected to the outer unit 5.

[0054] like Figure 7-10As shown, the inner layer unit 4 also includes an arc box 46, a counterweight 47, a memory spring 48 and a return spring 49. The arc box 46 is fixedly installed on the lower surface of the fixed end of the telescopic grid 45, and the counterweight 47 is slidably installed in the arc box 46. One end of the memory spring 48 is fixedly connected to the counterweight 47, and the other end is fixedly connected to the inner wall of the arc box 46. The counterweight 47 is fixedly connected to the telescopic end of the telescopic grid 45 through a pull rope. One end of the return spring 49 is fixedly connected to the ring plate 41, and the other end of the return spring 49 is slidably connected to the bottom extension of the cleaning basket 24.

[0055] When the driven elliptical gear 33 is meshed with the inner gear ring 34, the film sensor feeds back a signal to the controller, and the controller transmits current to the memory spring 48. At this time, the memory spring 48 contracts rapidly after receiving the current, thereby driving the counterweight 47 to move outward along the arc box 46. On the one hand, the telescopic grid 45 contracts under the action of the pull rope, and at the same time, the center of gravity of the telescopic grid 45 changes. As a result, under the action of the counterweight 47, the telescopic grid 45 compresses the torsion spring 44 and deflects rapidly around the round rod 43, thereby stirring the cleaning liquid. Because the driven elliptical gear 33 contacts the inner gear ring 34 when it rotates, the inner gear ring 34 rotates rapidly, thereby driving the ring plate 41 to rotate rapidly, thereby causing The telescopic grid 45 rotates rapidly, causing the telescopic grid 45 to produce periodic acceleration and deceleration motion, forming a pulsating water flow, enhancing the cavitation effect, and coordinating with the rapid flipping action of the telescopic grid 45, so that the cleaning liquid in the inner layer forms a spiral shear flow, which effectively cleans the items to be cleaned, further improving the cleaning effect of the items. When the driven elliptical gear 33 and the inner ring gear 34 are disengaged, the film pressure sensor 35 is no longer under pressure. At this time, the counterweight block 47 slowly resets and flips to a horizontal state under the action of the memory spring 48 and the restoring force of the torsion spring 44 itself. At the same time, the telescopic grid 45 extends again to intercept and split the generated bubbles, increase the time of the cavitation effect, and further improve the cleaning effect.

[0056] like Figure 11 As shown, the outer unit 5 includes a rack 51, a gear 52, a cylinder 53, a bent rod 54 and an impeller 55. The rack 51 is fixedly connected to the ring plate 41, the rack 51 is meshed with the gear 52, the gear 52 is fixedly connected to the cylinder 53, the cylinder 53 is rotatably connected to the bent rod 54, the bent rod 54 is fixedly connected to the cleaning basket 24, and the cylinder 53 is fixedly connected to the impeller 55.

[0057] When the counterweight 47 moves to the outside of the telescopic grid 45, the return spring 49 is squeezed to drive the ring plate 41 to move downward, causing the rack 51 to move downward while driving the gear 52 to rotate rapidly on the bent rod 54, thereby driving the impeller 55 to rotate under the transmission action of the cylinder 53, stirring the outer layer of cleaning liquid to form turbulence, and cooperating with the inner layer of spiral water flow to form a complex flow field, further improving the cleaning effect on objects.

[0058] like Figure 9 As shown, the memory spring 48 contracts faster than it extends.

[0059] In order to make the telescopic grid 45 flip quickly to form a spiral flow field to clean the objects, the ring plate 41 and the telescopic grid 45 rotate from fast to slow and then to fast to form a pulsating water flow, thereby enhancing the cavitation effect. When the telescopic grid 45 slowly returns to a horizontal state, the bubbles generated by the enhanced cavitation effect have a longer residence time or are split under the action of the telescopic grid 45, thereby further enhancing the cavitation effect and further improving the cleaning effect on the objects.

[0060] like Figure 9 As shown, the initial position of the counterweight 47 is located near the center end of the housing 1.

[0061] In order to facilitate the rapid contraction of the counterweight 47 and the rapid deflection of the telescopic grid 45, the cleaning liquid forms a spiral flow field, thereby improving the cleaning effect on the object.

[0062] like Figure 2 As shown, the housing 1 is composed of a shell 11 and a cover 12. The housing 1 is provided with a controller and a power switch.

[0063] To facilitate the user to start and stop the control device and receive and transmit controller signals.

[0064] like Figure 5 As shown, the gear ratio of the driving elliptical gear 32 to the driven elliptical gear 33 is 1:6-1:3.

[0065] In order to transmit the rotation of the driving elliptical gear 32 to the driven elliptical gear 33 to form rapid rotation, different gear ratios can adapt to different torques and meet the cleaning power requirements under different liquid levels.

[0066] Working principle of the present invention:

[0067] After the items to be cleaned are placed in the cleaning basket 24, the user closes the cover 12, and the controller controls the electric telescopic rod 42 to extend and engage with the inner gear ring 34, and presses the power switch. At this time, the ultrasonic generator 21 is started and transmits an electrical signal to the transducer 22, which converts the electrical signal into high-frequency sound wave vibration, generating a cavitation effect in the cleaning liquid. After bubbles are generated, the energy generated by the bubbles rising and bursting cleans the surface of the cleaning items, thereby completing the cleaning of the items.

[0068] The controller controls the drive motor 31 to start, thereby driving the active elliptical gear 32 to rotate. During the rotation of the active elliptical gear 32, it is always engaged with the driven elliptical gear 33, thereby driving the driven elliptical gear 33 to rotate. When the active elliptical gear 32 rotates to engage with the two ends of the long axis of the driven elliptical gear 33, or when the teeth at both ends of the long axis of the driven elliptical gear 33 are engaged with the inner ring gear 34, the diaphragm pressure sensor 35 is subjected to pressure. At this time, the diaphragm pressure sensor 35 feeds back the signal to the controller, and the controller transmits current to the memory spring 48. During the meshing and rotation of the driven elliptical gear 33 and the inner ring gear 34, the inner ring gear 34 is driven to rotate rapidly. When the inner ring gear 34 is disengaged from the driven elliptical gear 33, the inner ring gear 34 slowly reduces the rotation speed under the action of water flow resistance, thereby driving the ring plate 41 to rotate under the transmission action of the electric telescopic rod 42, causing the ring plate 41 to rotate rapidly, then slowly, and then rapidly.

[0069] When the driven elliptical gear 33 is meshed with the inner gear ring 34, the film sensor feeds back a signal to the controller, and the controller transmits current to the memory spring 48. At this time, the memory spring 48 contracts rapidly after receiving the current, thereby driving the counterweight 47 to move outward along the arc box 46. On the one hand, the telescopic grid 45 contracts under the action of the pull rope, and at the same time, the center of gravity of the telescopic grid 45 changes. As a result, under the action of the counterweight 47, the telescopic grid 45 compresses the torsion spring 44 and deflects rapidly around the round rod 43, thereby stirring the cleaning liquid. Because the driven elliptical gear 33 contacts the inner gear ring 34 when it rotates, the inner gear ring 34 rotates rapidly, thereby driving the ring plate 41 to rotate rapidly, thereby causing The telescopic grid 45 rotates rapidly, causing the telescopic grid 45 to produce periodic acceleration and deceleration motion, forming a pulsating water flow, enhancing the cavitation effect, and coordinating with the rapid flipping action of the telescopic grid 45, so that the cleaning liquid in the inner layer forms a spiral shear flow, which effectively cleans the items to be cleaned, further improving the cleaning effect of the items. When the driven elliptical gear 33 and the inner ring gear 34 are disengaged, the film pressure sensor 35 is no longer under pressure. At this time, the counterweight block 47 slowly resets and flips to a horizontal state under the action of the memory spring 48 and the restoring force of the torsion spring 44 itself. At the same time, the telescopic grid 45 extends again to intercept and split the generated bubbles, increase the time of the cavitation effect, and further improve the cleaning effect.

[0070] When the counterweight 47 moves to the outside of the telescopic grid 45, the return spring 49 is squeezed to drive the ring plate 41 to move downward, causing the rack 51 to move downward while driving the gear 52 to rotate rapidly on the bent rod 54, thereby driving the impeller 55 to rotate under the transmission action of the cylinder 53, stirring the outer layer of cleaning liquid to form turbulence, and cooperating with the inner layer of spiral water flow to form a complex flow field, further improving the cleaning effect on objects.
