Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a device for intermittent quantitative collection and cleaning of the bottom of a thermos cup and its cleaning method. Background Technology

[0002] During the manufacturing process of stainless steel insulated cups, the bottom and body need to be welded. The bottom is formed by stamping, and before welding, impurities such as oil and dust must be removed to ensure welding quality and the overall performance of the product. (Refer to...) Figure 1 As shown, a thin sheet structure with flanges 011 is typically used, where the flanges 011 often employ a slightly open structure to meet functional requirements. However, when two or more cup bottoms 01 are stacked concentrically in a transfer frame, a relatively sealed space is formed between the flanges 011. During stacking, handling, or transportation, when the cup bottoms 01 are subjected to external forces such as gravity, vibration, or manual handling, slight relative movements occur between the stacked cup bottoms 01, causing changes in the gas volume within the sealed space. This results in a negative pressure phenomenon, creating a vacuum adsorption effect that makes the cup bottoms 01 tightly adhered and difficult to separate. The stacking methods of the cup bottoms 01 are diverse, including forward stacking (the opening of the upper cup bottom 01 faces downward and the opening of the lower cup bottom 01 faces upward), reverse stacking (the bottom surfaces of the upper cup bottom 01 are in contact with the bottom surfaces of the lower cup bottom 01), and mixed stacking. Regardless of the stacking method, the negative pressure adsorption effect will prevent the cleaning liquid from penetrating into the contact surface between the cup bottoms 01, forming a cleaning dead zone in the adsorption area and affecting the cleaning effect. In addition to the micro-opening design of the flanged 011, cup bottoms with concave bottoms, cup bottoms with annular sealing edges, and other shapes and structures are also prone to similar negative pressure adsorption problems.

[0003] Currently, cleaning technology for components of insulated cups has seen some development. For example, Chinese utility model patent CN215613689U discloses an ultrasonic cleaning device for stainless steel cup lids. This device includes a frame, with a cleaning mechanism and a washing mechanism at the upper end of the frame. The cleaning mechanism is used to hold cleaning fluid and has an ultrasonic generator at the bottom. The cleaning mechanism includes a first housing and a cup lid holder, which is placed inside the first housing. The cup lid holder includes a main frame with several fixing brackets and fixing rings. The washing mechanism is used to hold water and includes a second housing and a water inlet / outlet device. A pulsator is located at the bottom of the second housing. This technology, by first cleaning the stainless steel cup lid with the cleaning mechanism and then washing it with the washing mechanism, can efficiently remove dust, stains, and oil from the stainless steel cup lid.

[0004] However, the aforementioned existing technologies mainly target the cleaning of cup lids and employ a static cleaning method, which has the following shortcomings: First, there is a lack of specialized cleaning design for the special structure of the cup bottom, where the concave structure and edges easily create cleaning dead zones; second, existing technologies mostly use batch static immersion cleaning methods, resulting in relatively low cleaning efficiency, which cannot meet the needs of large-scale continuous industrial production; third, there is a lack of effective quantitative collection and orderly arrangement mechanisms, leading to overlapping and accumulation of cleaned parts, affecting the automated processing of subsequent processes; finally, there is a lack of intelligent control functions for differentiated cleaning based on the degree of contamination, making it impossible to adjust cleaning parameters. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to provide a thermos cup bottom intermittent quantitative collection and cleaning device and cleaning method that can realize quantitative collection, all-round deep cleaning and intelligent parameter adjustment.

[0006] To solve the above-mentioned technical problems, the present invention provides an intermittent quantitative collection and cleaning device for the bottom of a thermos cup, comprising: A downwardly oriented receiving guide frame, with an overall slide structure, is used to receive and guide the bottom of a single cup to slide down. A quantitative settling structure, hinged to the outlet end of the receiving guide frame at its upper part, includes a fully enclosed sliding channel and a channel outlet with an intermittently closing door. The intermittently closing door can be controlled to open and close to achieve a quantitative output of the cup bottom. One side wall of the sliding channel has a guide ramp inclined towards the channel outlet, forming a limiting channel between the guide ramp and the other side wall. A dual-positioning space is formed between the lower part of the limiting channel and the channel outlet, used to accommodate two cup bottoms and position them in a first positioning part and a second positioning part, respectively. A flow conveying assembly, connected to the receiving guide frame, includes a variable pressure pump and a nozzle assembly, used to apply impact force to the cup bottom to drive its movement and simultaneously pre-clean the cup bottom.

[0007] Preferably, the first positioning part forms a groove-shaped structure and is misaligned relative to the second positioning part to ensure that the two cup bottoms can be stably positioned and do not interfere with each other.

[0008] Preferably, the intermittently closing door panel is driven by an electric hydraulic cylinder, and a limiting block is provided at one end of the relative sliding channel for limiting the bottom of the cup positioned in the second positioning part to achieve quantitative control.

[0009] The present invention also provides a method for cleaning the bottom of a cup based on the above-mentioned device, comprising the following steps: S1: Single cup bottom receiving stage, a single cup bottom enters the receiving guide frame and slides down the slide structure to the entrance of the sliding channel of the quantitative straightening structure; S2: Impact Drive and Pre-cleaning Stage. The flow assembly is activated, and the water flow generated by the variable pressure pump applies an impact force to the bottom of the cup, overcoming resistance and causing the bottom of the cup to enter the sliding channel. At the same time, the bottom of the cup is pre-cleaned. S3: Cleaning and positioning stage in the channel. The bottom of the cup is continuously cleaned during the sliding process in the sliding channel. After passing through the limiting channel, it enters the dual positioning space and is positioned in the second positioning part and the first positioning part in sequence. S4: Double cup bottom collaborative cleaning stage. After the two cup bottoms are positioned at the first positioning part and the second positioning part respectively, a fixed-point depth cleaning process is performed. S5: Quantitative output stage, controls the intermittent closing door to open, simultaneously outputting the cleaned bottoms of the two cups into the storage box.

[0010] More preferably, in step S3, a spiral impact cleaning is performed by multiple sets of high-pressure impact nozzles arranged along a spiral path on the inner wall of the sliding channel. These nozzles are tilted towards the center of the channel at different angles, so that the bottom of the cup completes 2-3 rotations during the sliding process, achieving a thorough cleaning of the surface without any dead angles.

[0011] More preferably, the spiral impact cleaning adopts a segmented pressure control strategy at the top, middle and bottom to ensure the cleaning effect while controlling the movement speed of the bottom of the cup.

[0012] More preferably, in step S4, a micro-rinsing nozzle is provided at the bottom of the first and second positioning parts of the dual positioning space to perform a positioning rinse, thereby cleaning a specific part of the bottom of the cup.

[0013] More preferably, in the dual-cup bottom collaborative cleaning mechanism, the high-pressure water flow from the lower nozzle generates a venturi effect and forms a negative pressure when passing through the gap between the cup bottoms, which powerfully sucks away the dirt and debris from the upper cup bottom. At the same time, the secondary shock wave formed by the water flow rebound provides additional cleaning to the bottom surface of the upper cup bottom.

[0014] More preferably, in step S2, the flow delivery component automatically configures the cleaning solution concentration and temperature according to the degree of contamination at the bottom of the cup, thereby achieving intelligent and differentiated cleaning.

[0015] More preferably, the water used in the cleaning process is treated through a two-stage filtration system: a primary 200-mesh stainless steel filter removes large particulate impurities, and a secondary activated carbon adsorption layer removes organic pollutants. The treated cleaning solution is then returned to the cleaning tank, achieving resource recycling.

[0016] The beneficial effects of this invention are as follows: Compared with existing technologies, this invention, by setting a guide ramp within the sliding channel to form a limiting channel, combined with the staggered design of the dual-positioning placement space, ensures that only two cup bottoms are positioned at a time without overlapping or accumulation. The variable pressure pump and nozzle assembly of the flow transport component achieve impact driving and pre-cleaning treatment of the cup bottoms. Multiple sets of high-pressure impact nozzles arranged along a spiral path ensure that the cup bottoms complete 2-3 rotations during the sliding process, achieving thorough cleaning without dead angles. Micro-flushing nozzles at the bottom of the dual-positioning placement space utilize the Venturi effect to create negative pressure suction and secondary shock waves for supplementary cleaning, achieving synergistic deep cleaning of both cup bottoms. Intelligent automatic configuration of cleaning fluid concentration and temperature, differentiated treatment based on the degree of contamination, improves cleaning efficiency. The secondary filtration system enables the recycling of cleaning fluid, reducing resource consumption. The entire device has a compact structure, a high degree of automation, and significant cleaning effect, making it suitable for large-scale industrial cup bottom cleaning operations.

Detailed Description of the Embodiments

[0019] Embodiment 1: With reference to Figure 2 , the present embodiment provides an intermittent quantitative collection device for the cup bottom of a vacuum cup, which is used for quantitatively collecting and arranging without overlapping the individual cup bottoms 01 that have undergone front-end separation treatment. The main body of the device is arranged beside the cleaning water tank 03, and the storage frame 02 is placed in the cleaning water tank 03.

[0020] The device includes two main components: a receiving guide frame 51 and a quantitative sorting structure 52. The receiving guide frame 51 adopts a slide structure that is large at the upper part and small at the lower part and is arranged obliquely downward, which includes a bottom plate and protective side plates on both sides to form a closed sliding channel. The large upper end of the receiving guide frame is butted with the conveying end of an external conveying mechanism (not shown in the figure) to receive the conveyed individual cup bottom 01. The upper part of the quantitative sorting structure 52 is hinged and communicated with the small lower end of the receiving guide frame 51, and is responsible for the quantitative collection and output of the cup bottoms, including a sliding channel 521 and a channel outlet 522.

[0021] The width W1 of the channel inlet 511 is designed to satisfy the dimensional relationship of D<W1<2D (where D is the diameter of the cup bottom 01). This dimensional restriction ensures that only one cup bottom 01 can enter the quantitative sorting structure 52 from the receiving guide frame 51 each time, preventing blockage caused by multiple cup bottoms entering at the same time. A rubber sheet 61 is embedded at the channel inlet 511 to increase the friction force with the cup bottom 01, so that the cup bottom pauses at the channel inlet 511 to wait for further control instructions from the system.

[0022] During the working process, the individual cup bottom 01 enters from the upper receiving end of the receiving guide frame 51, slides down along the guide frame under the action of gravity to the channel inlet 511, and pauses due to the frictional resistance of the rubber sheet 61; when the system issues a release instruction, the cup bottom 01 continues to slide through the sliding channel 521 toward the channel outlet 522, and finally falls into the storage frame 02 to complete the quantitative collection. Through size control and intermittent release mechanism, the device realizes individual quantitative collection of the cup bottoms 01, avoids overlapping accumulation, and improves the efficiency and quality of the subsequent cleaning process.

[0023] One side wall of the sliding channel 521 is provided with a guide ramp 524 inclined towards the channel outlet 522. A limiting channel 526 is formed between the guide ramp 524 and the other side wall. The width of the limiting channel 526 only allows a single cup bottom 01 to pass through. The limiting channel 526 extends downward to the channel outlet 522 to form a dual positioning space 525 for accommodating two cup bottoms 01. This space includes a first positioning part 5251 and a second positioning part 5252. The first positioning part 5251 is biased towards the guide ramp 524 and protrudes outward from the outer side of the sliding channel 521 through the shell wall, forming a groove-like structure. The space near the second positioning part 5252 is relatively larger and higher, that is, the bottom wall of the first positioning part 5251 is inclined relative to the upper wall rather than parallel. The second positioning part 5252 is adjacent to and higher than the first positioning part 5251. The two positioning parts serve as the final stable positioning positions of the two cup bottoms 01, respectively. The bottom edge of the second positioning part 5252 is inclined downwards from the right side wall of the sliding channel 521 towards the first positioning part 5251, and the bottom edge of the first positioning part 5251 is inclined downwards from the left side wall of the sliding channel 521 towards the second positioning part 5252. That is, the channel outlet 522 is inclined, see reference... Figure 9 Viewed from the perspective of the large surface parallel to the quantitative straightening structure 52, a better angle is when the channel outlet 522 is tilted at 4°-6° relative to the horizontal plane. This tilting design, on the one hand, utilizes the gravitational component generated by the tilt angle to assist the cup bottom 01 in a stable position at the channel outlet 522, preventing the cup bottom 01 from getting stuck or jammed at the outlet; on the other hand, it helps the cup bottom 01 to form a stable relative position within the dual positioning space 525, creating favorable conditions for subsequent dual cup bottom positioning.

[0024] The channel outlet 522 is provided with an intermittently closing door plate 523 that matches the bottom edge of the first positioning part 5251 and the second positioning part 5252. When the intermittently closing door plate 523 is closed, the cup bottom 01 can be lowered. After the first cup bottom 01 passes through the limiting channel 526 and falls to the second positioning part 5252, it will slide along the slope of the intermittently closing door plate 523 to the first positioning part 5251 and be restricted in the groove structure. The upper plane of the cup bottom 01 forms a V-shaped angle with the bottom wall of the second positioning part 5252. When the next cup bottom 01 slides down to the second positioning part 5252, since the upper plane of the first cup bottom 01 and the bottom wall of the second positioning part 5252 have formed a V-shaped angle, the movement of the second cup bottom 01 toward the first positioning part 5251 will be mechanically resisted by the upper end of the first cup bottom 01, which restricts the second cup bottom 01 to the limited space between the side wall of the first positioning part 5251 and the first cup bottom 01, preventing the second cup bottom 01 from continuing to penetrate into the first positioning part 5251, thereby realizing the layered positioning and stable placement of the two cup bottoms 01.

[0025] The quantitative output of the cup bottom 01 is achieved by controlling the opening and closing of the door panel 523. The intermittently closing door panel 523 is driven by an electric hydraulic cylinder 5231, and a hinged linkage plate is set between the hydraulic cylinder and the door panel to achieve control.

[0026] Furthermore, a limiting block 5232 is provided at one end of the intermittently closing door panel 523 opposite to the sliding channel 521. The limiting block 5232 is positioned against the top wall of the channel outlet 522. The spatial position and size of the limiting block 5232 are designed to ensure that the first cup bottom 01 is not blocked when it slides to the first positioning part 5251, while the second cup bottom 01 is effectively blocked by the limiting block 5232 after it falls into the second positioning part 5252. When the intermittently closing door panel 523 closes, the blocking effect of the limiting block 5232 maintains a small gap between the second cup bottom 01 and the first cup bottom 01, preventing them from getting stuck together when sliding out.

[0027] The structural parameters of the dual positioning space 525 can be set as follows: the width of the limiting channel 526 is set to the diameter D of the cup bottom 01 plus a gap of 2-3mm, which ensures that a single cup bottom can pass smoothly while preventing multiple cup bottoms from entering side by side. The height difference between the second positioning part 5252 and the first positioning part 5251 is controlled within the range of 5-10mm to ensure a stable height misalignment relationship between the two cup bottoms 01. The response time of the electric hydraulic cylinder 5231 is controlled within 0.5-1.0 seconds, with fast opening and closing action and accurate positioning, meeting the cycle time requirements of the automated production line.

[0028] The receiving guide frame 51 is connected to a flow delivery assembly 62, which is intermittently controlled by the system and integrates three major cleaning functions: pre-rinsing, surface activation, and stain loosening. The flow delivery assembly 62 is equipped with a cleaning solution preparation unit, connected to the cleaning tank 03 via a proportional regulating valve. It can automatically adjust the concentration of cleaning solution according to the degree of contamination at the bottom of the cup 01: 2-3% concentration for light contamination, 5-8% concentration for moderate contamination, and 10-12% concentration for heavy contamination. It also has a built-in temperature control device, using a PTC heating element to maintain the cleaning solution temperature within the range of 40-80℃. Room temperature cleaning is suitable for standard mode, medium temperature cleaning accelerates the dissolution of grease stains, and high temperature cleaning treats stubborn stains.

[0029] The nozzles of the flow assembly 62 are arranged in two layers: the upper nozzle group sprays to clean the upper surface, and the lower nozzle group sprays to clean the lower surface, ensuring comprehensive cleaning coverage of the cup bottom 01. The system is equipped with a variable pressure pump, which adjusts the water flow pressure within the range of 0.2-2.5MPa according to cleaning requirements, and adopts pulse cleaning technology to achieve intermittent high-pressure water flow impact through a control valve. This water flow drive system has a dual function: as a power system, it overcomes the frictional resistance between the cup bottom 01 and the rubber sheet 61 at the channel inlet 511 by controlling the water flow impact force, realizing the timed release and orderly conveying of the cup bottom 01; as a pre-cleaning system, it performs preliminary rinsing on the surface of the cup bottom 01 during its sliding process, removing dust, oil, and other impurities that may have adhered during the production process.

[0030] The water source for the flow transmission component 62 is directly drawn from the cleaning tank 03, achieving both the recycling of the cleaning solution and ensuring a certain level of cleaning capability. The component is equipped with a two-stage filtration and recovery system: a primary 200-mesh stainless steel filter removes large particulate impurities, and a secondary activated carbon adsorption layer removes organic pollutants. The water flowing after rinsing the bottom of the cup 01 ultimately flows back into the cleaning tank 03, mixes with the cleaning solution in the tank, and is purified and reused under the action of the circulation filtration system in the cleaning tank 03, forming a closed-loop water resource recycling system.

[0031] An angle adjustment component 527 is connected between the quantitative straightening structure 52 and the receiving guide frame 51. This component adopts a cylinder structure to drive the quantitative straightening structure 52 to rotate, adjusting the corresponding position of the channel outlet 522 in the storage frame 02, thereby achieving a rectangular arrangement of the cup bottoms 01 in the storage frame 02. The quantitative straightening structure 52 is connected to the receiving guide frame 51 via a rotating hinge, allowing for fine adjustment of the tilt angle according to the characteristics of cup bottoms 01 of different specifications, thus improving the system's adaptability.

[0032] Work process The specific working process of this device is divided into the following continuous stages: A single cup bottom 01 falls from the front-end conveying mechanism into the receiving guide frame 51. Under the action of gravity, it slides along the inclined guide frame. Due to the frictional resistance generated by the rubber sheet 61 embedded in the channel inlet 511, the cup bottom 01 will pause at the channel inlet 511, waiting for further control commands from the system. The system controls the flow delivery component 62 to start, spraying a constant pressure water flow to impact the cup bottom 01 paused at the channel inlet 511, overcoming the frictional resistance of the rubber sheet 61, and pushing the cup bottom 01 into the sliding channel 521. At the same time, the water flow pre-cleans the surface of the cup bottom 01, removing dust and oil stains adhering during the production process. Subsequently, the system shuts down the flow delivery component 62.

[0033] The cup bottom 01, entering the sliding channel 521, accelerates down the inclined angle and enters the dual positioning space 525 through the limiting channel 526. After passing through the limiting channel 526, the first cup bottom 01 falls to the second positioning part 5252, and then slides along its inclined bottom wall towards the first positioning part 5251, finally being stably positioned in the groove-shaped first positioning part 5251, with its upper end plane forming a V-shaped angle with the bottom wall of the second positioning part 5252. When the system restarts the current conveying component 62, the second cup bottom 01 is flushed into the sliding channel 521 and falls through the limiting channel 526 to the second positioning part 5252. Due to the mechanical resistance of the upper end plane of the first cup bottom 01, the second cup bottom 01 is restricted to the limited space between the side wall of the first positioning part 5251 and the first cup bottom 01, and cannot continue to penetrate into the first positioning part 5251, thus achieving layered positioning and partial overlapping placement of the two cup bottoms 01.

[0034] After two cup bottoms 01 are placed in the dual-positioning placement space 525, the system controls the electric hydraulic cylinder 5231 to drive the intermittently closing door 523 to open. Simultaneously, the limiting block 5232 releases its restraint on the cup bottoms 01 in the second positioning part 5252, allowing the two partially stacked cup bottoms 01 to separate individually and fall simultaneously from the inclined channel outlet 522, accurately placing them into the predetermined position in the storage frame 02. The two cup bottoms 01 maintain an appropriate distance in the storage frame 02, preventing the reformation of negative pressure adsorption and improving storage efficiency. After the intermittently closing door 523 completes one open-output-close cycle, the system re-enters the waiting state. The angle adjustment component 527 adjusts the rotation angle of the quantitative straightening structure 52 according to the filling status of the storage frame 02, changing the corresponding position of the channel outlet 522 in the storage frame 02, ensuring that the cup bottoms 01 are arranged in a rectangular, orderly manner in the storage frame 02.

[0035] Example 2: Spiral Impact Cleaning Device for Collecting Bottom of Thermos Cups Based on Example 1, this embodiment utilizes the natural rotational characteristics of the cup bottom 01 during the sliding process to achieve all-round cleaning through a spirally arranged multi-angle impact nozzle.

[0036] Spiral Impact Cleaning System 71 Multiple sets of high-pressure impact nozzles 711 are arranged along a spiral path on the inner wall of the sliding channel 521. Each set contains three nozzles, which are inclined towards the center of the channel at angles of 30°, 60°, and 90°, respectively. The spiral spacing is 0.8 times the diameter D of the cup bottom. When the cup bottom 01 slides down the inclined channel, it is subjected to continuous oblique impacts from the spirally arranged nozzles, naturally forming a rolling and rotating motion. The impact angle of each nozzle is calculated so that the cup bottom completes 2-3 full rotations during the 0.8-1.2 second sliding process, ensuring that the surface is rinsed without any dead corners.

[0037] The pressure control is divided into three stages: the upper stage starts rotation at 0.8-1.2MPa, the middle stage maintains stable rotation and deep cleaning at 1.5-2.0MPa, and the lower stage performs final cleaning and controls the outlet speed at 1.0-1.5MPa.

[0038] Drop-in flushing system 75 Miniature flushing nozzles 751 are respectively installed at the bottom of the first positioning part 5251 and the second positioning part 5252 of the dual positioning space 525. After the cup bottom 01 is settled and stabilized, the system starts pulse high-pressure flushing, and the ultra-fine high-pressure water jet is specifically used to impact the concave center of the cup bottom and the dead corners of the edges.

[0039] Dual-cup bottom collaborative cleaning mechanism: When both cup bottoms 01 are positioned simultaneously, the high-pressure water flow from the lower nozzle 751 generates a "Venturi effect" through the gap between the cup bottoms, creating negative pressure that powerfully sucks away dirt and debris from the upper cup bottom. Simultaneously, the rebounding water creates a secondary shock wave that further cleans the bottom surface of the upper cup bottom. The rinsing sequence is as follows: after the first cup bottom is positioned, a 0.5-second delay initiates a fixed-point rinse for 0.3 seconds; after the second cup bottom is positioned, a 0.2-second delay initiates a collaborative rinse for 0.4 seconds; and before opening the door, a final 0.1-second rapid rinse removes loose dirt.

[0040] Cleaning effect: The surface is covered without dead corners by rotation. The impact intensity at a fixed point in the stationary state is twice that in the moving state. The double cup bottom works together to generate a Venturi negative pressure suction effect, which greatly improves the overall cleaning effect.

[0041] Example 3: Intermittent quantitative collection and spiral impact cleaning method for the bottom of a thermos cup This embodiment provides an intermittent quantitative collection and cleaning method for the bottom of a thermos cup, combining quantitative collection technology and spiral impact cleaning technology to achieve collection, all-round cleaning, and orderly arrangement of the cup bottom. This method, through a complete process flow of "receiving - pretreatment - dynamic cleaning - static deep cleaning - quantitative output," ensures cleaning effectiveness while improving production efficiency. The entire cleaning process is divided into three stages: single cup bottom receiving and pretreatment, dynamic spiral impact cleaning, and static fixed-point deep cleaning.

[0042] In the single cup bottom receiving and preprocessing stage, a single cup bottom 01 enters the receiving guide frame 51 from the front-end conveying mechanism. Through size control (D<W1<2D), it is ensured that only one cup bottom passes through the channel inlet 511 at a time, and the cup bottom pauses at the channel inlet 511 under the frictional resistance of the rubber sheet 61 to wait for a processing instruction. At this time, the fluid delivery assembly 62 automatically configures the cleaning solution concentration according to the pollution degree: for light pollution, a concentration of 2-3% is used with treatment at a normal temperature of 40°C; for moderate pollution, a concentration of 5-8% is used with treatment at a medium temperature of 60°C; for heavy pollution, a concentration of 10-12% is used with treatment at a high temperature of 80°C. The variable pressure pump outputs a water flow of 0.5-1.0MPa to impact the cup bottom, which overcomes the frictional resistance and performs surface pre-cleaning at the same time to remove attached dust and oil stains.

[0043] In the dynamic spiral impact cleaning stage, after the cup bottom 01 enters the sliding channel 521, the high-pressure impact nozzles 711 arranged along the spiral path perform all-round cleaning. Each group of 3 nozzles is arranged to incline toward the center of the channel at angles of 30°, 60°, and 90°, and the spiral pitch is 0.8 times the diameter D of the cup bottom. A segmented pressure control strategy is adopted during the cleaning process, for example: 0.8-1.2MPa for the upper section, 1.5-2.0MPa for the middle section, and 1.0-1.5MPa for the lower section. The cup bottom completes 2-3 full rotations during the 0.8-1.2 second sliding process, and realizes continuous rotation by using natural gravity and angular impact to remove various stains and residues.

[0044] In the static fixed-point deep cleaning stage, the first cup bottom falls to the second positioning part 5252 through the limiting channel 526, and then slides along the inclined bottom wall into the groove-shaped structure of the first positioning part 5251 to achieve positioning. When the second cup bottom falls to the second positioning part 5252, it is mechanically restricted by the first cup bottom, so that the two cup bottoms form a stable state of layered positioning and partially overlapping arrangement. At this time, the micro flushing nozzle 751 at the bottom of the dual-positioning arrangement space 525 starts pulsed ultra-high-pressure fixed-point impact to clean the central recess and edge dead corners of the cup bottoms. When the high-pressure water flow from the lower nozzle passes through the gap between the cup bottoms, a Venturi effect is generated to form a negative pressure, which sucks away the stain debris of the upper cup bottom. Meanwhile, the secondary shock wave formed by the rebounding water flow performs supplementary cleaning on the bottom surface of the upper cup bottom.

[0045] The angle adjustment assembly 527 adjusts the rotation angle of the quantitative sorting structure 52 according to the filling condition of the storage frame 02, so as to ensure that the cup bottoms are arranged in an orderly rectangular array in the storage frame 02. The water flow used in the cleaning process is treated by a two-stage filtration system: the first-stage 200-mesh stainless steel filter screen removes large-particle impurities, and the second-stage activated carbon adsorption layer removes organic pollutants. The treated cleaning solution flows back to the cleaning tank 03 for recycling.
