Abstract

The present invention relates to the technical field of ultrasonic cleaning, and discloses an ultrasonic cleaning machine for removing scale on the surface of a metal pot body and a cleaning method thereof, including a cleaning frame. A cavity seat is fixedly connected inside the cleaning frame. A sliding groove is formed in the middle of the cavity seat. Symmetrical transducers are movably sleeved in the sliding groove. The top of the transducer is fixedly connected with an oscillator. Through the high-frequency mechanical vibration of the oscillator, the liquid continuously and rapidly passes through the one-way channel I and the one-way channel II, so that the liquid impacts the impellers in the channels. Under the control of the ratchet assembly, it can only rotate in one direction, so that the impellers in the two channels both rotate intermittently, and the two impellers provide a continuous force away from the center of the cavity seat to the oscillator, so that the oscillator rotates upward under the restriction of the sliding groove, so that the bubbles generated by the oscillator can be sprayed towards the metal pot body in a fan shape, so that the metal pot body can be cleaned comprehensively, and at the same time, the amount of bubbles blocked by the placing frame per unit time is reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic cleaning, and particularly to an ultrasonic cleaner for removing scale on the surface of a metal pot body and a cleaning method thereof. Background Art

[0002] An ultrasonic cleaner mainly converts ultrasonic waves into high-frequency mechanical vibrations through ultrasonic transducers, causing tens of thousands of tiny bubbles to be generated in the cleaning liquid by the connected vibrators. The bubbles maintain longitudinal movement under the action of the sound waves. When the bubbles move to the object to be cleaned, a cavitation effect occurs, generating shock waves to destroy the insoluble dirt on the object to be cleaned and completing the cleaning.

[0003] In existing ultrasonic cleaners, the vibrators are generally installed at the bottom of the cleaner. When cleaning a metal pot body, the metal pot body needs to be placed in a storage frame, and then the storage frame is placed into the cleaner for cleaning. However, due to the large number of frames in the storage frame, most of the tiny bubbles will be intercepted by the storage frame when moving towards the metal pot body, resulting in fewer bubbles contacting the metal pot body per unit time and slow cleaning efficiency of the metal pot body. At the same time, due to the irregular shape of the metal pot body, a large number of bubbles are blocked by the shape of the metal pot body itself, resulting in incomplete cleaning of the part of the metal pot body that is not directly facing the vibrator. It needs to be taken out and reoriented for secondary cleaning. Although more transducers and vibrators can be added to the cleaner to complete multi-directional cleaning, this will undoubtedly increase the manufacturing cost of the cleaner, and at the same time, more ultrasonic generators are required to complete the cleaning when it starts, further increasing the usage cost. Summary of the Invention

[0004] In view of the deficiencies existing in the prior ultrasonic cleaning machine in the background art during use, the present invention provides an ultrasonic cleaning machine and its cleaning method for removing scale on the surface of a metal pot body, which have the advantages of reciprocating vibration to make the liquid quickly pass through the one-way channel I and the one-way channel II, the liquid impacting the impeller in the channel to make it rotate, the rotation of the impeller providing a moving force for the vibrator, the vibrator reciprocatingly rotating in the track of the sliding groove to form a fan-shaped bubble group, the impeller driving the driven wheel to rotate synchronously and intermittently through a magnet, the extrusion protrusions on the driven wheel indirectly extruding the elastic rubber layer, the transition cavity expanding and compressing under the influence of the elastic rubber layer to complete the actions of extracting and transporting the liquid, the blocking rod reciprocatingly moving to indirectly block the liquid infusion channel I and the liquid infusion channel II for one-way liquid transmission, the change in the liquid volume in the liquid storage cavity causing a change in the weight of the vibrator, the change in the weight of the vibrator causing the impeller to be unable to lift the vibrator and the vibrator to fall back, the flipping of the vibrator causing a change in the position of the floating plate and the liquid in the liquid storage cavity, the floating of the floating plate under the buoyancy of the liquid to drive the movable rod to move to complete the spatial change of the reciprocating groove, the spatial change of the reciprocating groove providing a change in air pressure and affecting the movement of the limit plate, and the movement of the limit plate providing sufficient conditions for the movement of the blocking rod. It solves the technical problems proposed in the above background art that the bubbles are blocked by the storage rack, resulting in only a small part of the bubbles contacting the object to be cleaned, making the cleaning effect poor, and the diverse shapes of the metal pot body, resulting in difficulty for the bubbles to reach all parts of the metal pot body for rapid cleaning.

[0013] Preferably, symmetric air delivery channels are provided in the oscillator. One opening end of the air delivery channel is connected to the reciprocating groove. The other opening is connected to the end of the movable cavity away from the spring.

[0014] A method for removing scale from the surface of a metal pot body by using an ultrasonic cleaning machine includes the following cleaning steps:

[0015] S1. Place the frame with the metal pot body into the cleaning frame so that the metal pot body is immersed in the cleaning liquid. Then start the device. The transducer receives the ultrasonic wave output by the ultrasonic generator and converts it into high-frequency mechanical vibration, so that the oscillator synchronously performs high-frequency mechanical vibration to generate a large number of microbubbles.

[0016] S2. The bubbles move longitudinally towards the storage frame and the metal pot body, and under cavitation, clean the metal pot body.

[0017] S3. The water flow impacts the internal impeller through the one-way channel I and the one-way channel II. The impeller drives the oscillator to move upward along the track of the sliding groove, causing the bubbles generated by the oscillator to spray towards the metal pot body in a fan shape.

[0018] S4. The rotation of the impeller drives the rotation of the driven wheel, causing the extrusion protrusion to intermittently extrude the transition cavity. The transition cavity extracts the external liquid and inputs it into the liquid storage cavity through the liquid infusion channel II. The total weight of the oscillator increases, and the lifting force provided by the impeller fails, causing the oscillator to start to fall back.

[0019] S5. The position of the floating plate changes, increasing the air pressure in the reciprocating groove, changing the position of the limit plate, causing the blocking rod to slide and change its position, blocking the liquid infusion channel II, opening the liquid infusion channel I to enable the transition cavity to extract the liquid in the liquid storage cavity and spray it out, reducing the total weight of the oscillator. The impeller drives the oscillator to lift again, forming a reciprocating rotation to generate fan-shaped bubbles.

[0020] The present invention has the following beneficial effects:

[0021] 1. Through the high-frequency mechanical vibration of the oscillator, the liquid continuously and rapidly passes through the one-way channel I and the one-way channel II, causing the liquid to impact the impeller in the channels. Under the control of the ratchet assembly, it can only rotate in one direction, so that the impellers in both channels rotate intermittently, providing a continuous force for the oscillator to move away from the center of the inner cavity seat. Under the restriction of the sliding groove, the oscillator rotates upward, causing the bubbles generated by the oscillator to spray towards the metal pot body in a fan shape, enabling the metal pot body to be cleaned comprehensively, and at the same time reducing the amount of bubbles blocked by the storage frame per unit time.

[0022] 2. Through the intermittent rotation of the impeller in the one-way channel I, the magnet on it attracts the magnet on the inner side of the driven wheel, causing the driven wheel to rotate intermittently with it, so that the extrusion protrusion intermittently extrudes the elastic rubber layer, continuously changing the cavity volume of the transition cavity, thereby performing a suction action, enabling it to complete subsequent liquid transportation, providing a guarantee for the weight change of the oscillator. After the weight of the oscillator increases, the force provided by the impeller cannot lift it, and at this time, the oscillator rotates and falls back, so that the oscillator achieves the purpose of reciprocating rotation.

[0023] 3. In the present invention, through the indirect blockage of the infusion channel I and the infusion channel II, when the weight of the oscillator is relatively low, the impeller will drive the oscillator to move upward. At this time, the transition chamber can continuously input liquid into the liquid storage chamber through the infusion channel II, increasing the weight of the oscillator continuously. When the weight of the oscillator is greater than the force provided by the impeller, the oscillator will rotate downward to reset. Then, the infusion channel I will open, enabling the transition chamber to extract the liquid from the liquid storage chamber, reducing the weight of the oscillator continuously, allowing the impeller to drive the oscillator to rotate upward again, so that the oscillator can perform reciprocating motion, and the oscillator can continuously deliver fan-shaped distributed bubbles to the metal pot body, achieving the purpose of rapid cleaning.

[0024] 4. In the present invention, as the liquid in the liquid storage chamber increases continuously, the liquid presses the floating plate, causing the floating plate to drive the movable rod to press the space of the reciprocating groove. As a result, the air pressure received by the limiting plate increases continuously, causing the limiting plate to move and the spring to compress. When the liquid decreases, the buoyancy received by the limiting plate weakens. At this time, the compressed spring drives the limiting plate to reset, making the two through holes on the limiting plate intermittently coincide with the staggered chamber. Thus, the blocking rod can slide back and forth in the staggered chamber through the through holes under the inertial force of the oscillator, indirectly blocking the infusion channel I and the infusion channel II, providing guarantee for the input and discharge of the liquid.

[0025] 5. In the present invention, through the design of the large friction force of the movable rod, when the movable rod moves, it always moves slowly. Consequently, the movement of the limiting plate is always slow, enabling the blocking rod to wait at its original position for a longer time, providing a longer time for the input and output of the liquid (especially for the output of the liquid), avoiding the problem that when the liquid is output, the weight of the oscillator quickly balances with the force provided by the impeller again, resulting in the oscillator quickly rotating upward again and the liquid being input into the liquid storage chamber again, greatly reducing the reciprocating amplitude of the oscillator.

[0037] 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.

[0038] Please refer to Figures 1 to 3 , an ultrasonic cleaning machine for removing scale from the surface of a metal pot body and its cleaning method, including a cleaning frame 1, an inner cavity seat 2 fixedly connected inside the cleaning frame 1, the inner cavity seat 2 is in a suspended state, the left and right sides of the inner cavity seat 2 are symmetrically arc-shaped, a sliding groove 3 is opened in the middle of the inner cavity seat 2, symmetric transducers 4 are movably sleeved in the sliding groove 3, the bottom end of the transducer 4 is connected to an ultrasonic generator, a roller 5 is movably connected to the transducer 4, the roller 5 is located in the sliding groove 3, the top end of the transducer 4 is fixedly connected to a vibrator 6, the vibrator 6 reciprocates along the track direction of the sliding groove 3, so that the sliding groove 3 can limit the roller 5, so that the transducer 4 drives the vibrator 6 to reciprocate and rotate within the track of the sliding groove 3, so that the bubbles generated by the vibrator 6 rush towards the object to be cleaned in a fan shape, expanding the contact area between the object to be cleaned and the bubbles, reducing the loss of the bubbles by the storage frame, and improving the cleaning efficiency of the object to be cleaned.

[0039] Refer to Figures 4 to 6 , Figure 8A symmetrical liquid storage chamber 7 is provided in the vibrator 6, and a reciprocating groove 25 is provided at the bottom end of the liquid storage chamber 7. A movable rod 26 is movably sleeved in the reciprocating groove 25. The movable rod 26 is T-shaped, so that the movable rod 26 will not be separated from the reciprocating groove 25. The outer wall of the movable rod 26 is uneven, so that the reciprocating movement of the movable rod 26 is slow. In order to make the movement of the limit plate always slow, the blocking rod can wait for a longer time in the original position, providing a longer time for the input and output of the liquid (especially the output of the liquid), avoiding the problem that when the liquid is output, the weight of the vibrator quickly balances with the force provided by the impeller again, causing the vibrator to quickly rotate upward again, and the liquid is input into the liquid storage chamber again, so that the reciprocating amplitude of the vibrator is greatly reduced. A floating plate 27 is fixedly connected to the top of the movable rod 26. The density of the floating plate 27 is less than the density of water. The movable rod 26 It is on the same side as the infusion channel II 161, so that the floating plate 27 can float on the liquid. When liquid is input into the liquid storage chamber 7 and the floating plate 27 is above the movable rod 26, the floating plate 27 is affected by the buoyancy of the liquid, driving the movable rod 26 to move upward, so that the volume of the reciprocating groove 25 becomes larger. When the floating plate 27 is below the movable rod 26, the floating plate 27 is affected by the buoyancy of the liquid, driving the movable rod 26 to lift up, so that the volume of the reciprocating groove 25 becomes smaller. A symmetrical air transmission channel 24 is opened in the vibrator 6, one end of the air transmission channel 24 is connected to the reciprocating groove 25, and the other end is connected to the end of the active chamber 19 away from the spring 21, so that when the volume size of the reciprocating groove 25 changes, the pressure change can be transmitted to the active chamber 19 through the air transmission channel 24, and the limit plate 20 therein is worked, so that the limit plate 20 moves accordingly.

[0040] See also Figures 3 to 7 , Figure 9, both ends of the oscillator 6 are provided with a one-way channel I 8 and a one-way channel II 9. The opening of the one-way channel I 8 facing the inner cavity seat 2 at one end is larger than the opening at the other end, and the opening of the one-way channel II 9 facing the inner cavity seat 2 at one end is smaller than the opening at the other end, so that the liquid is accelerated when flowing from the large port to the small port. A positioning seat 10 is fixedly connected in both the one-way channel I 8 and the one-way channel II 9. A ratchet assembly 11 is arranged in the positioning seat 10. One end of the ratchet assembly 11 is fixedly connected with an impeller 12, so that the impeller 12 can only rotate in one direction. The impeller 12 in the one-way channel I 8 rotates in the opposite direction to the impeller 12 in the one-way channel II 9, and the force application directions are the same. When the oscillator 6 performs reciprocating high-frequency vibration, the liquid will pass through the one-way channel I 8 and the one-way channel II 9, so that the liquid quickly impacts the impeller 12, causing the two impellers 12 to rotate intermittently, and the impeller 12 provides a force for the oscillator 6 to move away from the center of the inner cavity seat 2. Under the restriction of the sliding groove 3, the oscillator 6 rotates upward along its trajectory. Magnets are arranged on the outer side of the impeller 12 in the one-way channel I 8 and the inner side of the driven wheel 13. The magnets on the impeller 12 and the magnets on the driven wheel 13 are opposite in polarity. When the impeller 12 in the one-way channel I 8 rotates, it can drive the driven wheel 13 to perform synchronous intermittent rotation through the mutual attraction of the magnets.

[0041] Refer to Figure 4 , Figure 7 , Figure 9 , a driven wheel 13 is movably sleeved in the oscillator 6. The center of the driven wheel 13 coincides with the center of the impeller 12 in the one-way channel I 8. One end of the driven wheel 13 is fixedly connected with evenly distributed extrusion protrusions 131. The extrusion protrusions 131 are arc-shaped and are smoothly designed at both ends. An annular cavity adapted to the driven wheel 13 is opened in the oscillator 6. Transition cavities 14 are opened at the top and bottom of the annular cavity. An elastic rubber layer 15 is fixedly connected to one end of the transition cavity 14 facing the extrusion protrusion 131. When the driven wheel 13 rotates intermittently synchronously with the impeller 12, the extrusion protrusions 131 on it can intermittently extrude the elastic rubber layer 15, causing the elastic rubber layer 15 to compress and expand, so that the transition cavity 14 can perform a suction action to complete the transportation of the liquid.

[0042] Refer to Figure 5 , Figure 7, symmetric infusion channels Ⅰ 16 and infusion channels Ⅱ 161 are provided in the vibrator 6. Two symmetric one-way valves are provided in both the infusion channels Ⅰ 16 and the infusion channels Ⅱ 161. Both ends of the infusion channels Ⅰ 16 and the infusion channels Ⅱ 161 are respectively connected to the outside and the liquid storage cavity 7, so that the transition cavity 14 can extract the liquid in the liquid storage cavity 7 through the infusion channels Ⅰ 16 and send it to the outside, and the transition cavity 14 can extract the liquid from the outside through the infusion channels Ⅱ 161 and input it into the liquid storage cavity 7. When the vibrator 6 is at the lowest position, the infusion channels Ⅰ 16 are above the infusion channels Ⅱ 161, the port of the infusion channels Ⅰ 16 communicating with the liquid storage cavity 7 is above, and the port of the infusion channels Ⅱ 161 communicating with the liquid storage cavity 7 is below. When the vibrator 6 rotates upward and flips, the infusion channels Ⅰ 16 can be at the bottom, and the infusion channels Ⅱ 161 are at the top at this time. When draining the liquid, the liquid in the liquid storage cavity 7 always submerges the port of the infusion channels Ⅰ 16, and before the blocking rod 18 turns, the liquid in the liquid storage cavity 7 is discharged to the maximum extent. The infusion channels Ⅰ 16 are connected to the upper transition cavity 14, and the infusion channels Ⅱ 161 are connected to the lower transition cavity 14.

[0043] Refer to Figure 5 , two groups of pairwise symmetric staggered cavities 17 are provided in the vibrator 6. The staggered cavities 17 are linear. Both ends of the staggered cavities 17 are respectively connected to the infusion channels Ⅰ 16 and the infusion channels Ⅱ 161. The two staggered cavities 17 are respectively on both sides of the transition cavity 14. A blocking rod 18 is movably sleeved in the staggered cavities 17. One end of the blocking rod 18 abuts against the limiting plate 20, so that the blocking rod 18 can slide in the staggered cavities 17 and be fixed under the influence of the limiting plate 20, so that when it is fixed, it blocks the infusion channels Ⅰ 16 or the infusion channels Ⅱ 161, achieving the purpose of draining liquid or infusing liquid separately.

[0044] Refer to Figure 5 , Figure 10, two sets of symmetrically arranged movable cavities 19 are provided inside the oscillator 6. The two movable cavities 19 respectively penetrate through the centers of the two staggered cavities 17. One end of the movable cavity 19 is fixedly connected to a spring 21, and one end of the spring 21 is fixedly connected to a limiting plate 20. Two through holes 22 are provided on the limiting plate 20, so that under the influence of the spring 21 and the air pressure in the reciprocating groove 25, the limiting plate 20 makes slow reciprocating movements in the movable cavity 19, so that the two through holes 22 intermittently coincide with the staggered cavity 17, and the blocking rod 18 passes through the through holes 22 to achieve the purpose of commutation. Inclined protrusions 23 are provided in the through holes 22, and inclined surfaces are provided at the opposite ends of the two inclined protrusions 23. When the blocking rod 18 faces the inclined protrusion 23 with the inclined surface, it will impact on the inclined surface, causing an additional displacement of the limiting plate 20, increasing the overlapping area of the through hole 22 and the staggered cavity 17. At this time, the blocking rod 18 will pass through the through hole 22 to complete the commutation. At this time, the spring 21 will drive the limiting plate 20 to reset to compensate for the additional displacement increased by the blocking rod 18, so that the blocking rod 18 faces the end of the inclined protrusion 23 where the inclined surface is not provided at this time, and the inclined protrusion 23 quickly restricts the displacement of the blocking rod 18.

[0045] The usage method (working principle) of the present invention is as follows:

[0046] First, input the cleaning liquid into the cleaning frame 1, and then hang the frame with the pot to be cleaned on the outer edge of the cleaning frame 1. At this time, the pot to be cleaned is immersed in the cleaning liquid. Then, start the device, so that the transducer 4 receives the ultrasonic wave output by the ultrasonic generator and converts it into high-frequency mechanical vibration, so that the oscillator 6 synchronously performs high-frequency mechanical vibration, so that the oscillator 6 generates tens of thousands of tiny bubbles, and the bubbles move longitudinally towards the cleaning frame with the pot to be cleaned, and the bubbles complete the cleaning of the pot under cavitation. At this time, the oscillator 6 vibrates back and forth at high frequency in the left and right directions (the directions of the two openings of the one-way channel I 8). When the oscillator 6 vibrates and displaces towards the side close to the center of the inner cavity seat 2, the water flow rushes towards the impeller 12 inside it through the larger port of the one-way channel I 8, causing the impeller 12 in the one-way channel I 8 to rotate. At the same time, the water flow rushes towards the impeller 12 inside it through the smaller port of the one-way channel II 9. At this time, the ratchet assembly 11 in the one-way channel II 9 hinders the rotation of the impeller 12 inside it. Then, when the oscillator 6 vibrates and displaces towards the side away from the center of the inner cavity seat 2, the water flow rushes towards the impeller 12 inside it through the larger port of the one-way channel II 9, causing the impeller 12 in the one-way channel II 9 to rotate. At the same time, the water flow rushes towards the impeller 12 inside it through the smaller port of the one-way channel I 8. At this time, the ratchet assembly 11 in the one-way channel I 8 hinders the rotation of the impeller 12 inside it. Thus, the impellers 12 in the two channels drive the oscillator 6 to move away from the inner cavity seat 2 when rotating, causing the rollers 5 to roll in the sliding groove 3, so that the transducer 4 and the oscillator 6 move and rise along the sliding groove 3, and the bubbles generated by the oscillator 6 are sprayed towards the pot to be cleaned in a fan shape for comprehensive and rapid cleaning;

[0047] Then, when the oscillator 6 is at the lowest position in the inner cavity seat 2, the infusion flow channel I 16 is above, and the infusion flow channel II 161 is below. At this time, the blocking rod 18 is on one side of the infusion flow channel I 16, blocking the infusion flow channel I 16, and the infusion flow channel II 161 is opened. There is less liquid in the liquid storage cavity 7, and the floating plate 27 drives the movable rod 26 to slowly lift upward under the buoyancy provided by the liquid, reducing the air pressure on the two limit plates 20, causing the spring 21 to drive the limit plates 20 to slowly move in the direction close to the one-way channel I 8. Then, when the impeller 12 in the one-way channel I 8 rotates intermittently and rapidly, the magnet on it will attract the magnet inside the driven wheel 13, causing the driven wheel 13 to rotate intermittently and rapidly synchronously with the impeller 12, so that the extrusion protrusion 131 intermittently passes through the transition cavity 14 on one side of the infusion flow channel II 161 and extrudes the elastic rubber layer 15 here. When the extrusion protrusion 131 leaves, the elastic rubber layer 15 resumes its original state, causing the volume of the transition cavity 14 here to change continuously, so that the transition cavity 14 absorbs the liquid in the cleaning frame 1 through the infusion flow channel II 161 and transports it to the liquid storage cavity 7. During the upward rotation of the oscillator 6, the liquid in the liquid storage cavity 7 continuously increases. At the same time, when the oscillator 6 has not rotated more than ninety degrees, the liquid in the liquid storage cavity 7 will drive the floating plate 27 to lift, causing the floating plate 27 to lift to the highest position. At this time, the air pressure on the limit plate 20 is the smallest, the spring 21 is in a normal state, and at the same time, the through hole 22 close to the spring 21 is at the position of the staggered cavity 17, and the inclined surface of the inclined protrusion 23 here faces away from the blocking rod 18 above;

[0048] Finally, when the vibrator 6 starts to rotate upward more than ninety degrees, the infusion channel II 161 will be above the infusion channel I 16, and the floating plate 27 will be inverted and below the movable rod 26. At this time, the vibrator 6 continues to lift up, and the liquid in the liquid storage chamber 7 continues to increase, so that the liquid continuously pushes the floating plate 27 to lift up, so that the floating plate 27 pushes the movable rod 26 to slowly compress the space of the reciprocating groove 25 (the friction force of the movable rod 26 is relatively large), so that the air pressure in the reciprocating groove 25 increases, and is transmitted to the limit plate 20 through the air transmission channel 24, so that the limit plate 20 is pressed and slowly moves in the direction of the spring 21, so that the perforation 22 away from the spring 21 gradually overlaps with the staggered cavity 17, and at the same time, the overall weight of the vibrator 6 continues to increase, so that the force provided by the impeller 12 is insufficient to rotate the vibrator 6 upward, so that the vibrator 6 begins to rotate downward rapidly under its own weight and resets. At this time, the infusion channel II 161 continues to input liquid into the liquid storage chamber 7. Then, the inclined protrusion 23 at the perforation 22 that begins to overlap with the staggered cavity 17, its inclined surface is opposite to the blocking rod 18 on the side of the infusion channel I 16, so that the blocking rod 18 squeezes the inclined surface of the inclined protrusion 23 under the inertial force generated by the vibration of the vibrator 6, so that the perforation 22 here completely overlaps with the staggered cavity 17, so that the blocking rod 18 moves, so that the blocking rod 18 blocks the infusion channel II 161. At this time, the spring 21 drives the limit plate 20 to reset a distance. At this time, the inclined surface of the inclined protrusion 23 here deviates from the blocking rod 18, so that the blocking rod 18 is restricted and cannot move, so that the infusion channel II 161 is blocked, and the infusion channel Ⅰ16 is opened, and then, the transition chamber 14 communicated with the infusion channel Ⅰ16 extracts the liquid in the liquid storage chamber 7 and discharges the vibrator 6. At this time, the vibrator 6 continues to move downward, and the liquid in the liquid storage chamber 7 is continuously discharged, so that the total weight of the vibrator 6 is continuously reduced. When the vibrator 6 rotates so that the infusion channel Ⅰ16 is again above the infusion channel Ⅱ161, the floating plate 27 is again above the movable rod 26, so that the floating plate 27 drives the movable rod 26 to move slowly upward under the buoyancy, so that the air pressure on the limit plate 20 is continuously reduced, and the limit plate 20 is slowly reset. When the weight of the vibrator 6 is continuously reduced, the impeller 12 drives the vibrator 6 to rotate upward again. At this time, the infusion channel Ⅰ16 is still in the drainage state. At this time, the vibrator 6 will move to the highest point. At this time, the floating plate 27 is no longer affected by the liquid Due to the influence of buoyancy, the spring 21 pushes the limit plate 20 to reset, so that the gas in the gas delivery channel 24 enters the reciprocating groove 25, pushing the movable rod 26 to move slowly, so that the volume of the reciprocating groove 25 increases. Then, the perforation 22 close to the spring 21 coincides with the staggered cavity 17 again. At this time, the blocking rod 18 on the side of the infusion channel II 161 squeezes the inclined surface of the inclined protrusion 23 at the perforation 22 under the inertial force provided by the vibrator 6, so that the blocking rod 18 moves to the side of the infusion channel I 16 again, so that the blocking rod 18 blocks the infusion channel I 16, and the infusion channel II 161 is opened again, so that the infusion channel II 161 inputs liquid into the liquid storage cavity 7 again, so that the weight of the vibrator 6 continues to increase again until it exceeds the force provided by the impeller 12, so that the vibrator 6 moves down again.Finally, each component repeats the above actions to quickly complete the cleaning.
