Description

Technical Field

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

[0002] Ultrasonic cleaning technology is an advanced technology that efficiently cleans the surface of an object based on physical effects such as cavitation effect, rectilinear flow effect, and acceleration effect generated when ultrasonic waves propagate in a liquid. Among them, the cavitation effect is one of the most crucial action mechanisms in the ultrasonic cleaning process. When ultrasonic waves propagate in a liquid, alternating dense and sparse regions are formed inside the liquid. In the negative pressure region, the distance between liquid molecules is stretched. When the tensile force exceeds the cohesive force of the liquid, the liquid molecules break to form tiny cavitation bubbles. These cavitation bubbles quickly collapse in the positive pressure region, generating local high temperature, high pressure, and intense shock waves, thereby peeling off the dirt on the surface of the object.

[0003] In existing split-type ultrasonic cleaning machines, ultrasonic transducers are usually directly installed at the bottom or side of the cleaning tank, and the propagation path and mode of the ultrasonic waves generated by them in the liquid are relatively single. The ultrasonic waves gradually attenuate as the distance increases during propagation, resulting in a weakened ultrasonic intensity in the region far from the transducer, restricting the generation and rupture process of cavitation bubbles, and having a short cavitation action time.

[0004] In addition, the liquid flow in the cleaning tank is relatively gentle, and the residence time of cavitation bubbles in the liquid is limited, making it difficult to fully exert their cleaning effect. When the cavitation bubbles quickly rise and collapse, the generated shock waves and high temperature and high pressure environment cannot fully act on the surface of the object, thereby reducing the cleaning effect.

[0005] Existing split-type ultrasonic cleaning machines lack an effective turbulence formation mechanism. The liquid mainly relies on natural convection to flow in the cleaning tank, with a slow flow rate and a single flow pattern, making it difficult to form strong local turbulence on the surface of the object. The lack of local turbulence results in a low relative movement speed between the liquid and the surface of the object, which is not conducive to the peeling and diffusion of dirt.

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

[0007] The purpose 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 purpose, the present invention provides the following technical solutions:

[0009] The described split-type ultrasonic cleaner includes a housing, a generating unit, a driving unit, an inner layer unit, and an outer layer unit. The housing is placed on a horizontal ground. The generating unit is fixedly connected to the housing. The driving unit is fixedly connected to the housing. 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 a turbulent flow.

[0010] The housing is used to install and fix the generating unit, the driving unit, the inner layer unit, and the outer layer unit. The generating unit is used for generating ultrasonic waves. The driving unit is used to start the inner layer unit to form a liquid spiral flow. The outer layer unit is used for forming a turbulent flow of the outer liquid. After placing the items to be cleaned, ultrasonic waves are generated by the generating unit for cleaning. The driving unit is used to control the start of the inner layer unit to make the internal cleaning liquid form a spiral flow, and the outer layer unit is used to make the cleaning liquid on the outside form a turbulent disturbance. Utilizing the strong mixing characteristics of the turbulent flow and the directional scouring ability of the spiral flow, it breaks through the limitation of the single cavitation effect of traditional ultrasonic cleaning and significantly improves the cleaning efficiency of complex items.

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

[0012] After the item to be cleaned is placed in the cleaning basket and the user covers the cover, the controller controls the electric telescopic rod to extend and engage with the internal gear ring. After pressing the power switch, the ultrasonic generator starts at this time, transmits an electrical signal to the transducer, converts this electrical signal into a high-frequency acoustic vibration, generates a cavitation effect in the cleaning liquid, generates bubbles, and the energy generated when the bubbles rise and burst is used to clean the surface of the cleaning item, thereby completing the cleaning of the item.

[0013] Furthermore, the driving unit includes a driving motor, a driving elliptical gear, a driven elliptical gear, an internal gear ring and a thin film pressure sensor. The fixed end of the driving motor is fixedly installed on the upper surface of the housing. The output shaft of the driving motor penetrates through the housing 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 internal gear ring. Thin film pressure sensors are arranged on the tooth surfaces at both ends of the major axis of the driven elliptical gear. A plurality of clamping holes are arranged at one end of the internal gear ring close to the horizontal ground. The driven elliptical gear is rotationally connected to the housing through a connecting rod. The internal gear ring is rotationally connected to the inner surface of the housing at one end away from the horizontal ground.

[0014] The controller controls the driving motor to start, thereby driving the driving elliptical gear to rotate. During the rotation of the driving elliptical gear, it is always meshed with the driven elliptical gear, thereby driving the driven elliptical gear to rotate. When the driving elliptical gear rotates to be meshed with both ends of the major axis of the driven elliptical gear, or when the teeth at both ends of the major axis of the driven elliptical gear are meshed with the internal gear ring, at this time, the thin film pressure sensors are both subjected to pressure. At this time, the thin film pressure sensors feed back signals to the controller, and the controller sends current to the memory spring. During the meshing rotation of the driven elliptical gear and the internal gear ring, the internal gear ring is driven to rotate rapidly. When the internal gear ring disengages from the driven elliptical gear, the rotational speed of the internal gear ring slowly decreases under the action of water flow resistance, thereby driving the ring plate to rotate under the transmission of the electric telescopic rod, so that the ring plate performs a cyclic action of rotating rapidly, rotating slowly, and then rotating 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 installed 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 diamond-shaped holes are formed 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 rotationally connected to the telescopic grid. The ring plate is fixedly connected to the outer layer unit.

[0016] Furthermore, the inner layer unit further includes an arc-shaped box, a counterweight, a memory spring and a return spring. The arc-shaped box is fixedly installed on the lower surface of the fixed end of the telescopic grid. The counterweight is slidably installed in the arc-shaped 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-shaped box. The counterweight is fixedly connected to the end of 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 is slidably connected to the extended part of the bottom of the cleaning basket.

[0017] When the driven elliptical gear meshes with the internal gear ring, the thin-film sensor feeds back a signal to the controller, and the controller supplies current to the memory spring. At this time, after receiving the current, the memory spring rapidly contracts, driving the counterweight to move outward along the arc-shaped box. On the one hand, under the action of the pulling rope, while the telescopic grid contracts, due to the change in the center of gravity of the telescopic grid, under the action of the counterweight, the telescopic grid compresses the torsion spring and rapidly deflects around the round rod, thereby agitating the cleaning liquid. Because when the driven elliptical gear rotates and contacts the internal gear ring, the internal gear ring rotates rapidly, driving the ring plate to rotate rapidly, causing the telescopic grid to rotate rapidly, making the telescopic grid generate periodic acceleration and deceleration movements, forming pulsating water flow, enhancing the cavitation effect, and cooperating with the rapid flipping action of the telescopic grid, thereby forming a spiral shear flow of the inner-layer cleaning liquid to powerfully clean the item to be cleaned, further improving the cleaning effect of the item. When the driven elliptical gear disengages from the internal gear ring, the thin-film pressure sensor is no longer pressed. At this time, under the action of the restoring forces of the memory spring and the torsion spring itself, the counterweight slowly resets and flips to the horizontal state, while the telescopic grid extends again, intercepting and splitting the generated bubbles, increasing the time of the cavitation effect, and further improving the cleaning effect.

[0018] Further, 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, by squeezing the return spring, the ring plate is driven to move downward, causing the rack to move downward and driving the gear to rotate rapidly on the bent rod. Thus, under the transmission of the cylinder, the impeller is driven to rotate, agitating the outer-layer cleaning liquid to form a turbulent flow, and cooperating with the inner-layer spiral water flow to form a complex flow field, further improving the cleaning effect on the item.

[0020] Further, the contraction speed of the memory spring is greater than the elongation speed.

[0021] In order to enable the telescopic grid to rapidly flip to form a spiral flow field to clean the item, while cooperating with the rapid-to-slow-to-rapid rotation process of the ring plate and the telescopic grid to form pulsating water flow and enhance the cavitation effect, when the telescopic grid slowly resets to the horizontal state, the residence time of the bubbles generated by the enhanced cavitation effect will be increased or split under the action of the telescopic grid, further improving the cavitation effect and further improving the cleaning effect on the item.

[0022] Further, the initial position of the counterweight is located at one end close to the center of the housing.

[0023] To facilitate the rapid contraction of the counterweight block, causing the telescopic grid to deflect rapidly, forming a spiral flow field of the cleaning liquid and improving the cleaning effect on the article.

[0024] Further, the outer shell is composed of a housing and a cover opening. A controller is provided on the outer shell, and a power switch is provided on the outer shell.

[0025] To facilitate the user to control the start and stop of the device and the reception and transmission of controller signals.

[0026] Further, the tooth number ratio of the active elliptical gear to the driven elliptical gear is 1:6 - 1:3.

[0027] To enable the rotation of the active elliptical gear to be transmitted to the driven elliptical gear to form a rapid rotation, and at the same time, different tooth number ratios can adapt to different torques to meet the cleaning power requirements at different liquid levels.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. In the present invention, the controller controls the driving motor to start, thereby driving the active elliptical gear to rotate. During the rotation of the active elliptical gear, it is always engaged with the driven elliptical gear, thereby driving the driven elliptical gear to rotate. When the active elliptical gear rotates to be engaged with both ends of the major axis of the driven elliptical gear, or when the teeth at both ends of the major axis of the driven elliptical gear are engaged with the internal gear ring, at this time, the thin film pressure sensor is subjected to pressure. At this time, the thin film pressure sensor feeds back the signal to the controller, and the controller sends current to the memory spring. During the rotation of the driven elliptical gear engaged with the internal gear ring, the internal gear ring is driven to rotate rapidly. When the internal gear ring disengages from the driven elliptical gear, the internal 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 perform a cyclic action of rapid rotation to slow rotation and then to rapid rotation.

[0030] 2. When the driven elliptical gear meshes with the internal gear ring, the thin-film sensor feeds back a signal to the controller, and the controller supplies current to the memory spring. At this time, after receiving the current, the memory spring rapidly contracts, driving the counterweight to move outward along the arc-shaped box. On the one hand, under the action of the pull rope, while the telescopic grid contracts, due to the change in the center of gravity of the telescopic grid, under the action of the counterweight, the telescopic grid compresses the torsion spring and rapidly deflects around the round rod, thereby agitating the cleaning liquid. Because when the driven elliptical gear rotates and contacts the internal gear ring, the internal gear ring rotates rapidly, driving the ring plate to rotate rapidly, causing the telescopic grid to rotate rapidly, making the telescopic grid generate periodic acceleration and deceleration movements, forming pulsating water flow, enhancing the cavitation effect, and cooperating with the rapid flipping action of the telescopic grid, thereby forming a spiral shear flow of the cleaning liquid in the inner layer, powerfully cleaning the item to be cleaned, and further improving the cleaning effect of the item. When the driven elliptical gear disengages from the internal gear ring, the thin-film pressure sensor is no longer pressurized. At this time, under the action of the restoring forces of the memory spring and the torsion spring itself, the counterweight slowly resets and flips to the horizontal state, while the telescopic grid extends again, intercepting and splitting the generated bubbles, increasing the time of the cavitation effect, and further improving the cleaning effect.

[0031] 3. When the counterweight moves to the outside of the telescopic grid, by squeezing the return spring, the ring plate is driven to move downward, causing the rack to move downward and driving the gear to rotate rapidly on the bent rod at the same time. Under the transmission action of the cylinder, the impeller is driven to rotate, agitating the cleaning liquid in the outer layer to form a turbulent flow, cooperating with the spiral water flow in the inner layer to form a complex flow field, and further improving the cleaning effect on the item.

[0032] 4. Through the synergistic effect of the outer layer unit forming a turbulent flow and the inner layer unit forming a spiral diversion, a composite flow field of outer layer turbulent disturbance and inner layer spiral shear is formed in the cleaning basket. Utilizing the strong mixing characteristics of the turbulent flow and the directional scouring ability of the spiral flow, breaking through the limitation of the single cavitation effect of traditional ultrasonic cleaning, and significantly improving the cleaning efficiency of complex workpieces.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Embodiment: AsFigures 1-11 As shown in the figure, the present invention provides a technical solution:

[0047] As Figure 1 and Figure 3 shown, a split ultrasonic cleaner includes a housing 1, a generating unit 2, a driving unit 3, an inner layer unit 4 and an outer layer unit 5. The housing 1 is placed on a horizontal ground. The generating unit 2 is fixedly connected to the housing 1. The driving unit 3 is fixedly connected to the housing 1. The inner layer unit 4 is used to drive the outer layer unit 5 to start. The inner layer unit 4 is fixedly connected to the outer layer unit 5. The inner layer unit 4 is movably connected to the generating unit 2. The outer layer unit 5 is fixedly connected to the generating unit 2. The outer layer unit 5 has the function of forming a turbulent flow.

[0048] The housing 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 for generating ultrasonic waves. The driving unit 3 is used to start the inner layer unit 4 to form a liquid spiral flow. The outer layer unit 5 is used for forming a turbulent flow of the outer liquid. After placing the item to be cleaned, ultrasonic waves are generated by the generating unit 2 for cleaning. The driving unit 3 controls the start of the inner layer unit 4 to make the internal cleaning liquid form a spiral flow, and the outer layer unit 5 makes the cleaning liquid on the outside form a turbulent disturbance. Utilizing the strong mixing characteristics of the turbulent flow and the directional scouring ability of the spiral flow, it breaks through the limitation of the single cavitation effect of traditional ultrasonic cleaning and significantly improves the cleaning efficiency of complex items.

[0049] As Figure 4 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 installed at the bottom inside the housing 1. The transducer 22 is fixedly installed above the partition 23. The partition 23 is fixedly installed on one side inside the housing 1 close to the horizontal ground. The bottom of the cleaning basket 24 abuts against the upper surface of the partition 23. The cleaning basket 24 is provided with a fixing column 26. The cleaning basket 24 is snap-connected to the mounting ring 25 through the fixing column 26. The mounting ring 25 is fixedly installed on one side inside the housing 1 away from the horizontal ground. The cleaning basket 24 is movably connected to the inner layer unit 4 and fixedly connected to the outer layer unit 5.

[0050] After the item to be cleaned is placed in the cleaning basket 24, after the user closes the cover 12, the controller controls the electric telescopic rod 42 to extend and engage with the internal gear ring 34. Press the power switch. At this time, the ultrasonic generator 21 starts, transmits an electrical signal to the transducer 22, converts this electrical signal into a high-frequency acoustic vibration, generates a cavitation effect in the cleaning liquid, generates bubbles, and the energy generated when the bubbles rise and burst cleans the surface of the cleaning item, thus completing the cleaning of the item.

[0051] As Figure 3 and Figure 5As shown, the driving unit 3 includes a driving motor 31, a driving elliptical gear 32, a driven elliptical gear 33, an internal gear ring 34, and a thin-film pressure sensor 35. The fixed end of the driving motor 31 is fixedly installed on the upper surface of the housing 1. The output shaft of the driving motor 31 penetrates through the housing 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 internal gear ring 34. Thin-film pressure sensors 35 are arranged on the tooth surfaces at both ends of the major axis of the driven elliptical gear 33. Multiple clamping holes are arranged at one end of the internal gear ring 34 close to the horizontal ground. The driven elliptical gear 33 is rotationally connected to the housing 1 through a connecting rod. The internal gear ring 34 is rotationally connected to the inner surface of the end of the housing 1 away from the horizontal ground.

[0052] The controller controls the driving motor 31 to start, thereby driving the driving elliptical gear 32 to rotate. During the rotation of the driving elliptical gear 32, it is always meshed with the driven elliptical gear 33, thereby driving the driven elliptical gear 33 to rotate. When the driving elliptical gear 32 rotates to be meshed with both ends of the major axis of the driven elliptical gear 33, or when the teeth at both ends of the major axis of the driven elliptical gear 33 are meshed with the internal gear ring 34, at this time, the thin-film pressure sensors 35 are both subjected to pressure. At this time, the thin-film pressure sensors 35 feed back signals to the controller, and the controller supplies current to the memory spring 48. During the meshing rotation of the driven elliptical gear 33 and the internal gear ring 34, the internal gear ring 34 is driven to rotate rapidly. When the internal gear ring 34 disengages from the driven elliptical gear 33, the internal gear ring 34 slowly reduces the rotation speed under the action of water flow resistance, thereby driving the ring plate 41 to rotate under the transmission of the electric telescopic rod 42, so that the ring plate 41 performs a cyclic action of rotating quickly, then slowly, and then quickly again.

[0053] As Figure 6 、 Figure 7 shown, the inner layer 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 installed 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, and the other end of the torsion spring 44 is fixedly connected to the fixed end of the telescopic grid 45. Multiple groups of diamond-shaped holes are formed 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 rotationally connected to the telescopic grid 45. The ring plate 41 is fixedly connected to the outer layer unit 5.

[0054] As Figures 7-10As shown, the inner layer unit 4 further includes an arc-shaped box 46, a counterweight 47, a memory spring 48 and a return spring 49. The arc-shaped box 46 is fixedly installed on the lower surface of the fixed end of the telescopic grid 45. The counterweight 47 is slidably installed in the arc-shaped 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-shaped box 46. The counterweight 47 is fixedly connected to the end of 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 meshes with the internal gear ring 34, the thin film sensor feeds back a signal to the controller, and the controller delivers current to the memory spring 48. At this time, after receiving the current, the memory spring 48 quickly contracts, thereby driving the counterweight 47 to move outward along the arc-shaped box 46. On the one hand, under the action of the pull rope, while the telescopic grid 45 contracts, due to the change in the center of gravity of the telescopic grid 45, under the action of the counterweight 47, the telescopic grid 45 compresses the torsion spring 44 and quickly deflects around the round rod 43 at the same time, thereby agitating the cleaning liquid. Because when the driven elliptical gear 33 rotates and contacts the internal gear ring 34, the internal gear ring 34 rotates quickly, thereby driving the ring plate 41 to rotate quickly, so that the telescopic grid 45 rotates quickly, causing the telescopic grid 45 to generate periodic acceleration and deceleration movements, forming pulsating water flow, enhancing the cavitation effect, and cooperating with the quick flipping action of the telescopic grid 45, thereby forming a spiral shear flow of the cleaning liquid in the inner layer, powerfully cleaning the items to be cleaned, and further improving the cleaning effect of the items. When the driven elliptical gear 33 disengages from the internal gear ring 34, the thin film pressure sensor 35 is no longer pressurized. At this time, the counterweight 47 slowly resets and flips to the horizontal state under the action of the restoring forces of the memory spring 48 and the torsion spring 44, while the telescopic grid 45 extends again, intercepting and splitting the generated bubbles, increasing the time of the cavitation effect, and further improving the cleaning effect.

[0056] As Figure 11 As shown, the outer layer 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. The cylinder 53 is fixedly connected to the impeller 55.

[0057] When the counterweight 47 moves to the outside of the telescopic grid 45, by squeezing the return spring 49, it drives the ring plate 41 to move downward, causing the rack 51 to move downward and driving the gear 52 to rotate quickly on the bent rod 54 at the same time. Thus, under the transmission of the cylinder 53, the impeller 55 is driven to rotate, agitating the cleaning liquid in the outer layer to form a turbulent flow, and cooperating with the spiral water flow in the inner layer to form a complex flow field, further improving the cleaning effect on the items.

[0058] As Figure 9 shown, the contraction speed of the memory spring 48 is greater than the elongation speed.

[0059] In order to enable the telescopic grid 45 to quickly flip to form a spiral flow field for cleaning the article, while cooperating with the process of the annular plate 41 and the telescopic grid 45 rotating from fast to slow and then to fast to form a pulsating water flow, enhancing the cavitation effect. When the telescopic grid 45 slowly resets to the horizontal state, the residence time of the bubbles generated by the enhanced cavitation effect is increased or the bubbles are split under the action of the telescopic grid 45, further improving the cavitation effect and further improving the cleaning effect on the article.

[0060] As Figure 9 shown, the initial position of the counterweight 47 is located at one end close to the center of the outer shell 1.

[0061] In order to facilitate the rapid contraction of the counterweight 47 to cause the telescopic grid 45 to deflect rapidly, so that the cleaning liquid forms a spiral flow field and improves the cleaning effect on the article.

[0062] As Figure 2 shown, the outer shell 1 is composed of a shell body 11 and a cover opening 12. A controller is provided on the outer shell 1, and a power switch is provided on the outer shell 1.

[0063] In order to facilitate the user to control the start and stop of the device and the reception and transmission of controller signals.

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

[0065] In order to enable the rotation of the driving elliptical gear 32 to be transmitted to the driven elliptical gear 33 to form a rapid rotation, and at the same time, different tooth number ratios can adapt to different torques to meet the cleaning power requirements at different liquid levels.

[0066] The working principle of the present invention:

[0067] After the article to be cleaned is placed in the cleaning basket 24, after the user covers the cover opening 12, the controller controls the electric telescopic rod 42 to extend and engage with the internal gear ring 34. After pressing the power switch, the ultrasonic generator 21 is started at this time, and an electric signal is transmitted to the transducer 22, which converts this electric signal into a high-frequency acoustic vibration, generates a cavitation effect in the cleaning liquid, generates bubbles, and the energy generated when the bubbles rise and burst cleans the surface of the cleaning article, thereby completing the cleaning of the article.

[0068] The controller controls the driving motor 31 to start, thereby driving the driving elliptical gear 32 to rotate. During the rotation of the driving elliptical gear 32, it is always engaged with the driven elliptical gear 33, thereby driving the driven elliptical gear 33 to rotate. When the driving elliptical gear 32 rotates to engage with both ends of the major axis of the driven elliptical gear 33, or when the teeth at both ends of the major axis of the driven elliptical gear 33 engage with the internal gear ring 34, at this time, the thin-film pressure sensor 35 is subjected to pressure. At this time, the thin-film pressure sensor 35 feeds back a signal to the controller, and the controller supplies current to the memory spring 48. During the rotation of the driven elliptical gear 33 engaged with the internal gear ring 34, it drives the internal gear ring 34 to rotate rapidly. When the internal gear ring 34 disengages from the driven elliptical gear 33, the internal gear ring 34 slowly reduces its rotational speed under the action of water flow resistance, thereby driving the ring plate 41 to rotate under the transmission of the electric telescopic rod 42, causing the ring plate 41 to perform a cyclic action of rapid rotation to slow rotation and then to rapid rotation.

[0069] When the driven elliptical gear 33 is engaged with the internal gear ring 34, the thin-film sensor feeds back a signal to the controller, and the controller supplies current to the memory spring 48. At this time, after receiving the current, the memory spring 48 rapidly contracts, thereby driving the counterweight 47 to move outward along the arc-shaped box 46. On the one hand, under the action of the pull rope, while the telescopic grid 45 contracts, due to the change in the center of gravity of the telescopic grid 45, under the action of the counterweight 47, the telescopic grid 45 compresses the torsion spring 44 and rapidly deflects around the round rod 43 at the same time, thereby agitating the cleaning liquid. Because when the driven elliptical gear 33 rotates and contacts the internal gear ring 34, the internal gear ring 34 rotates rapidly, thereby driving the ring plate 41 to rotate rapidly, thereby causing the telescopic grid 45 to rotate rapidly, causing the telescopic grid 45 to generate periodic acceleration and deceleration motions, forming pulsating water flow, enhancing the cavitation effect, and cooperating with the rapid flipping action of the telescopic grid 45, thereby forming a spiral shear flow of the inner-layer cleaning liquid, powerfully cleaning the item to be cleaned, and further improving the cleaning effect of the item. When the driven elliptical gear 33 disengages from the internal gear ring 34, the thin-film pressure sensor 35 is no longer pressured. At this time, the counterweight 47 slowly resets and flips to the horizontal state under the action of the restoring forces of the memory spring 48 and the torsion spring 44, and at the same time, the telescopic grid 45 extends again, intercepting and splitting the generated bubbles, increasing the time of the cavitation effect, and further improving the cleaning effect.

[0070] When the counterweight 47 moves to the outside of the telescopic grid 45, by squeezing the return spring 49, it drives the ring plate 41 to move downward, causing the rack 51 to move downward and driving the gear 52 to rotate rapidly on the bent rod 54 at the same time. Thereby, under the transmission of the cylinder 53, it drives the impeller 55 to rotate, agitating the outer-layer cleaning liquid to form turbulence, and cooperating with the inner-layer spiral water flow to form a complex flow field, further improving the cleaning effect on the item.
