Description

Technical Field

[0001] This invention relates to the field of cleaning technology, and more specifically to a computer keyboard cleaning device. Background Technology

[0002] Computer keyboard cleaning devices are used to clean dust, debris, stains and other contaminants from computer keyboards, keeping them in good working order and hygienic.

[0003] Existing cleaning methods for equipment suffer from performance degradation with each cleaning session when dealing with a large number of keyboards. For example, cleaning adhesives lose their stickiness after repeated use, becoming less effective at removing dust and leaving residue on the keyboards after subsequent cleanings. Furthermore, the wear and tear on the keyboard surfaces from cleaning brushes and cloths accumulates with each cleaning session, resulting in widespread damage to keyboard surfaces when handling a large number of keyboards. In addition, frequent tool changes and cloth washing during continuous cleaning are not only time-consuming and labor-intensive but also disrupt the cleaning process, hindering efficient and consistent cleaning operations. This poses a significant challenge for locations like internet cafes and school computer labs with a large number of keyboards requiring regular cleaning, severely impacting the efficiency and quality of cleaning work.

[0021] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0022] 1. The vibration mechanism, consisting of a fan, resonant component, vibration transmission component, and adsorption component, achieves both keyboard adsorption and a slight vibration effect. The fan provides suction to the adsorption component, securing it to the back of the keyboard. This suction passes through the resonant and vibration transmission components. The resonant component transmits vibration waves using the suction from the fan, while the vibration transmission component collects these waves and further transmits them to the keyboard after adsorption. During cleaning, the adsorption component's fixation of the keyboard's back ensures stability, while the resonant and vibration transmission components convert the vibrations into waves that are transmitted to the keyboard. This slight vibration helps separate hard-to-reach dust and debris hidden deep in the keyboard's crevices, reducing the difficulty of further cleaning.

[0023] 2. Through the porous spray block, stirring and electrostatic assembly, and discharging assembly in the cleaning mechanism of the vibration mechanism, electrostatics can be applied to the polyethylene particles transmitted by the cleaning mechanism, and the keyboard can be cleaned using the electrostatically applied polyethylene particles. The porous spray block sprays the electrostatically applied polyethylene particles onto the keyboard's usable surface, while the stirring and electrostatic assembly applies electrostatics and stirs the polyethylene particles transmitted by the cleaning mechanism to improve the coverage of electrostatic application to the polyethylene particles. The discharging assembly limits the air pressure within the stirring and electrostatic assembly; the discharging assembly only discharges when the air pressure within the stirring and electrostatic assembly reaches a certain level. When the specified value is reached, the dispensing component will transfer the polyethylene particles to the porous spray block using the air pressure in the stirring and electrified unit. This completes the cleaning of the keyboard with the electrostatically charged polyethylene particles. The timing of the release of polyethylene particles is determined by controlling the air pressure in the stirring and electrified unit using the dispensing component. Dispensing will only occur when the air pressure reaches the specified value. This ensures that each spray of polyethylene particles has sufficient power, avoiding premature release due to insufficient pressure, which would reduce the cleaning efficiency of the polyethylene particles on the keyboard, and also avoiding premature release due to excessive pressure, which would damage the keyboard.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The present invention will be further described below with reference to embodiments.

[0040] Example: Refer to Figures 1 to 12 A computer keyboard cleaning device, comprising:

[0041] Base 1;

[0042] Vibration mechanism 2 includes a box 21 fixedly connected to the upper end face of the base 1. A fan 22 is fixedly connected to the upper end face of the box 21. An electric slider 23 is provided at the top inside the box 21. Two electro-hydraulic rods 25 and a gas delivery component 24 are provided at the bottom of the electric slider 23. A resonance component 26, a vibration transmission component 27 and an adsorption component 28 are provided in sequence at the telescopic end of the electro-hydraulic rods 25. Stabilizing components 29 are provided on both inner walls of the box 21.

[0043] The cleaning mechanism 3 includes a cleaning box 31 located on the lower part of the inner wall of the box 21 and two symmetrical stirring and electrified components 35 about the cleaning box 31. Arc-shaped multi-hole spray blocks 32 are fixedly connected to the inner walls of the cleaning box 31 and the stirring and electrified components 35 on both sides. Multiple material discharge components 36 are arranged in a linear array on the side of the stirring and electrified components 35 facing the cleaning box 31, and the stirring and electrified components 35 are connected to the arc-shaped multi-hole spray blocks 32 through the material discharge components 36. A recycling box 33 is fixedly connected to the bottom of the cleaning box 31. A suction pipe 34 is fixedly connected to the center of the bottom of the recycling box 33. An input / output component 37 connected to the stirring and electrified components 35 and the suction pipe 34 is provided on the side of the box 21.

[0044] The cleaning mechanism 4 is located on the upper surface of the base 1 and is connected to the input / output component 37.

[0045] The exhaust fan 22 in the vibration mechanism 2 provides suction to the adsorption component 28, enabling the adsorption component 28 to adsorb the back of the keyboard. When the exhaust fan 22 provides suction to the adsorption component 28, it passes through the resonance component 26 and the vibration transmission component 27. Therefore, the resonance component 26 converts the energy of the suction into vibration waves, and the vibration transmission component 27 collects and guides the vibration waves to the keyboard. After the vibration mechanism 2 completes the adsorption of the keyboard, the cleaning mechanism 4 begins to convey pressurized polyethylene granules into the stirring and electrifying component 35 in the cleaning mechanism 3. The stirring and electrifying component 35 can apply static electricity to the conveyed polyethylene granules, thereby making the polyethylene granules statically charged. The discharge component 36 controls the air pressure in the stirring and electrifying component 35 so that the polyethylene granules have sufficient power to enter the arc-shaped porous spray block 32 and spray onto the usable surface of the keyboard. The recycling box 33 and the suction pipe 34 can pick up the used polyethylene granules.

[0046] Reference Figures 2 to 4A controller is installed on the side of the housing 21. An inlet 211 is opened on the upper part of the housing 21 away from the input / output component 37. A slide rail 212 is fixedly connected to the center of the top of the housing 21. An electric slider 23 is slidably connected to the slide rail 212 and electrically connected to the controller. A connecting block 231 is fixedly connected to both sides of the electric slider 23. A connecting pipe 232 is fixedly connected to the input end of the connecting block 231. The other end of the connecting pipe 232 is connected to the exhaust fan 22 and electrically connected to the controller. An electro-hydraulic rod 25 is fixedly connected to the electric slider 23 and electrically connected to the controller.

[0047] By utilizing the sliding of the electric slider 23 in the slide rail 212, the electro-hydraulic rod 25, the resonance component 26, the vibration transmission component 27 and the adsorption component 28 can be moved synchronously, thereby achieving the adsorption of the keyboard entering from the inlet 211, thus moving the keyboard to the position inside the housing 21 corresponding to the cleaning mechanism 3. The electro-hydraulic rod 25 can realize the lifting and lowering of the adsorbed keyboard, so that the keyboard can be as close as possible to the cleaning mechanism 3 during cleaning.

[0048] Reference Figures 4 to 6 The gas delivery assembly 24 includes an elastic rod 241 fixedly connected to the side of the electric slider 23 away from the housing 21. A diverter 242 is fixedly connected to the side of the elastic rod 241 away from the electric slider 23. Both output ends of the diverter 242 are fixedly connected to a delivery pipe 243, and both input ends of the diverter 242 are fixedly connected to a transmission pipe 244.

[0049] The resonant assembly 26 includes a vibration isolation box 261 fixedly connected to the telescopic end of the electro-hydraulic rod 25. The side of the transmission pipe 244 away from the shunt 242 is connected to the vibration isolation box 261. Multiple resonant ball strings 262 are fixedly connected to the internal rectangular array of the vibration isolation box 261.

[0050] The elastic rod 241 in the gas delivery assembly 24 can provide fixation for the distributor 242, and at the same time, it can keep the distributor 242 and the resonant assembly 26 moving synchronously. The distributor 242 can transmit the suction force transmitted by the exhaust fan 22 to the vibration isolation box 261 of the resonant assembly 26 through the transmission pipe 244, so that the suction force collides with the resonant ball string 262 in the vibration isolation box 261, causing the resonant ball string 262 to generate vibration waves.

[0051] Reference Figures 5 to 6The vibration transmission component 27 includes a vibration stabilizing box 271 fixedly connected to the bottom of the vibration isolation box 261. A perforated plate 272 is embedded in the bottom of the vibration stabilizing box 271. Multiple ball bearings 273 are in contact with the side of the perforated plate 272 facing the vibration stabilizing box 271. A vibration guide rod 274 is fixedly connected to the center of the top of the vibration stabilizing box 271. The end of the vibration guide rod 274 away from the vibration stabilizing box 271 passes through the perforated plate 272 and extends into the adsorption component 28. At least two vibration concentration covers 275 are fixedly connected from top to bottom to the shaft of the vibration guide rod 274 located in the vibration stabilizing box 271. The opening direction of the vibration concentration cover 275 faces the vibration isolation box 261. A vibration guide block 276 is fixedly connected to the end of the vibration guide rod 274 away from the vibration stabilizing box 271.

[0052] The vibration wave generated by the resonant ball string 262 can be collected by the vibration concentrator 275 in the vibration transmission component 27 and further transmitted to the vibration guide rod 274. The vibration guide rod 274 can transmit the vibration wave to the vibration guide block 276. When the adsorption component 28 completes the adsorption, the vibration guide block 276 transmits the vibration wave to the back of the keyboard. Furthermore, since the vibration stabilizing box 271 and the vibration isolation box 261 are connected, the suction force will also pass through the vibration stabilizing box 271, so that the multiple balls 273 collide with each other under the influence of the suction force.

[0053] Reference Figure 3 , Figure 5 , Figure 7 The adsorption component 28 includes a conical cover 281 fixedly connected to the bottom of the vibration stabilizer box 271, a vibration guide block 276 located inside the conical cover 281, and a rubber ring 282 fixedly connected to the bottom of the conical cover 281. The outer circumferential surface of the rubber ring 282 is provided with a plurality of air holes 283 in an annular array.

[0054] The stabilizing component 29 includes a storage box 291 that is slidably connected to the inner wall of the box 21. Multiple spring rods 292 are linearly and fixedly connected to the inner wall of the storage box 291 along its length. The other ends of the multiple spring rods 292 are all fixedly connected to an L-shaped plate 293. Multiple rollers 294 are linearly and rotatably connected to both sides of the L-shaped plate 293.

[0055] The conical cover 281 and rubber ring 282 in the adsorption component 28 can gather the suction power delivered by the exhaust fan 22 to adsorb the back of the keyboard. The air hole 283 in the rubber ring 282 is used to realize the flow of suction gas so that the suction gas can continuously act on the resonant component 26. Since the storage box 291 in the stabilizing component 29 is slidably connected to the box body 21, when the L-shaped plate 293 clamps and fixes the edge of the keyboard by the spring rod 292, the storage box 291 can move synchronously with the keyboard to further limit the position of the keyboard and prevent the position from shifting due to the impact of polyethylene particles during cleaning.

[0056] Reference Figures 9 to 10 The stirring and electrified assembly 35 includes a pressure box 351 fixedly connected to the inner wall of the housing 21. Electrostatic discharge rods 352 are fixedly connected to the inner walls of opposite sides of the pressure box 351 and are electrically connected to the controller. A rotating rod 353 is fixedly connected to the center position of the length direction inside the pressure box 351. The rotating rod 353 has a built-in motor and is electrically connected to the controller. Multiple stirring racks 354 are fixedly connected to the rod of the rotating rod 353 in a linear array. A material transfer pipe 355 is fixedly connected to the side of the pressure box 351, and a guide pipe 341 is fixedly connected to the side of the suction pipe 34.

[0057] The electrostatic discharge rod 352 in the stirring and electrifying assembly 35 can be used to apply static electricity to the polyethylene particles transported by the cleaning mechanism 4. The rotating rod 353, with its stirring frame 354, can stir the polyethylene particles that have been electrostatically applied into the pressure box 351, thereby increasing the coverage of the electrostatic discharge rod 352 on the polyethylene particles. At the same time, as the cleaning mechanism 4 continuously transports polyethylene particles with pressurized gas, the air pressure in the pressure box 351 will continuously rise until it reaches the release value specified by the discharge assembly 36.

[0058] Reference Figures 9 to 11 The cleaning box 31 is fixedly connected to the pressure box 351 on the side away from the box body 21. The discharge assembly 36 includes a fixed frame 361 fixedly connected to the side of the pressure box 351 facing the cleaning box 31. The fixed frame 361 passes through the pressure box 351 and communicates with the arc-shaped multi-hole spray block 32. A pair of discharge doors 362 with opposite opening directions are hinged to the inner center of the fixed frame 361. A pair of hydraulic gate stops 363 corresponding to the position of the discharge doors 362 are fixedly connected to the inner bottom of the fixed frame 361 on the side away from the pressure box 351.

[0059] The opening or closing of the discharge gate 362 in the discharge assembly 36 allows the pressurized polyethylene particles inside the pressure box 351 to be released into the arc-shaped porous spray block 32 when the discharge gate 362 is open, while the closing of the discharge gate 362 prevents the pressure box 351 from communicating with the arc-shaped porous spray block 32. The raising and lowering of the hydraulic gate stop 363 is used to control the opening of the discharge gate 362.

[0060] Reference Figures 1 to 8 The input / output assembly 37 includes a fixing plate 371 fixedly connected to the side of the housing 21. A first suction pump 372 is fixedly connected to the upper end of the fixing plate 371. The input end of the first suction pump 372 is connected to the guide pipe 341. The output end of the first suction pump 372 is fixedly connected to the discharge pipe 373. A support frame is fixedly connected to the upper end of the fixing plate 371. A material collection box 374 is fixedly connected to the upper end of the support frame. The two output ends of the material collection box 374 are respectively connected to two material transfer pipes 355. The input end of the material collection box 374 is fixedly connected to the feed pipe 375.

[0061] The first suction pump 372 in the input / output component 37 can provide suction to the suction pipe 34 to complete the recycling of the used polyethylene particles into the cleaning mechanism 4. The collection box 374 and the transfer pipe 355 realize the transfer of the polyethylene particles compressed by gas in the cleaning mechanism 4 to the pressure box 351.

[0062] Reference Figure 1 , Figure 12 The cleaning mechanism 4 includes a pressure unit 41 fixedly connected to the upper surface of the base 1. The end of the feed pipe 375 away from the material collection box 374 is connected to the output end of the pressure unit 41. Polyethylene granules are stored in the pressure box of the pressure unit 41. A cleaner 42 is fixedly connected to the upper surface of the base 1 through a support leg. The end of the discharge pipe 373 away from the first suction pump 372 is connected to the input end of the cleaner 42. A dryer 43 is fixedly connected to the side of the cleaner 42. An inner rib pipe 44 is fixedly connected to the bottom of the dryer 43. A second suction pump 45 is fixedly connected to the upper surface of the base 1. The input end of the second suction pump 45 is connected to the inner rib pipe 44 through a pipe. The output end of the second suction pump 45 is connected to the input end of the pressure unit 41 through a pipe.

[0063] The pressurizer 41 in the cleaning mechanism 4 can combine with air to form pressurized polyethylene particles containing polyethylene particles, and then transfer them to the pressure box 351 through the transfer pipe 355. The used polyethylene particles sucked by the first suction pump 372 will enter the cleaner 42 through the discharge pipe 373. The cleaner 42 cleans the impurities adsorbed by the used polyethylene particles, and after cleaning, the cleaner 42 will transport the polyethylene particles to the dryer 43 for drying, and then re-enter the pressurizer 41 through the inner rib pipe 44 and the second suction pump 45.

[0064] The specific operating principle of this embodiment is as follows:

[0065] Step 1: The operator controls the electric slider 23 via the controller to slide it on the slide rail 212. This causes the electric slider 23 to move the connected electro-hydraulic rod 25, resonance component 26, vibration transmission component 27, and adsorption component 28 to a position near the keyboard inlet 211. Simultaneously, the exhaust fan 22 starts. The operator then places the keyboard into the inlet 211 (with the back of the keyboard facing the electric slider 23 and the usable side facing the cleaning mechanism 3). The controller then lowers the electro-hydraulic rod 25, and the exhaust fan 22 provides suction to the adsorption component 28. Therefore, the conical cover 281 and rubber ring 282 in the adsorption component 28 effectively collect the suction from the exhaust fan 22. The air holes 283 on the outer circumference of the rubber ring 282... The flow of suction gas is ensured, achieving stable adsorption of the keyboard (the suction force generated by the exhaust fan 22 is greater than the amount of gas leaked from the vent 283. This difference in force allows a stable negative pressure environment to be formed between the rubber ring 282 and the keyboard when adsorbing the keyboard, thus tightly adsorbing the keyboard). In addition, the stabilizing components 29 on both sides of the housing 21 also play an auxiliary role in fixing the keyboard. The spring rod 292 on the inner wall of the storage box 291 in the stabilizing component 29 is connected to the L-shaped plate 293. The rollers 294 on both sides of the L-shaped plate 293 can roll on the edge of the keyboard and clamp and fix it. The sliding connection between the storage box 291 and the housing 21 allows it to move synchronously with the movement of the keyboard, further ensuring the stability of the keyboard's position inside the housing 21.

[0066] The suction force generated by the start of the exhaust fan 22 is transmitted to the gas delivery component 24 through the connecting pipe 232 and the connecting block 231, and then the gas delivery component 24 divides the flow so that it is transmitted to the resonance component 26, the vibration transmission component 27, and finally to the adsorption component 28.

[0067] When the suction airflow passes through the gas delivery assembly 24: the elastic rod 241 in the gas delivery assembly 24 not only supports the diverter 242, but also ensures that the diverter 242 can stably maintain synchronous displacement with the electric slider 23 and the resonant assembly 26, thereby ensuring the stability of the airflow during the transmission process, so that the suction can be accurately transmitted to the vibration isolation box 261 of the resonant assembly 26 through the transmission pipe 244.

[0068] When the suction airflow passes through the resonant component 26, the suction is transmitted from the transmission pipe 244 to the vibration isolation box 261, causing the resonant ball string 262 in the vibration isolation box 261 to vibrate due to the impact of the airflow. These vibration waves propagate in the vibration isolation box 261 and are captured by the vibration concentration cover 275 in the vibration transmission component 27. Since the opening of the vibration concentration cover 275 faces the vibration isolation box 261, it can guide the vibration waves propagating in the vibration isolation box 261 directly into the internal space of the vibration concentration cover 275, reducing energy scattering and loss, and effectively accumulating vibration energy. At the same time, based on the principle of resonance, when the vibration frequency of the resonant ball string 262 is close to the natural frequency of the vibration concentration cover 275, resonance will occur, further enhancing energy absorption and storage, and allowing the vibration energy to be superimposed and enhanced. Therefore, the vibration concentration cover 275 can collect the vibration energy from the resonant ball string 262 and stably transmit it to the vibration guide block 276 along the vibration guide rod 274.

[0069] When the suction airflow passes through the vibration transmission component 27: Since the vibration stabilizing box 271 and the vibration isolation box 261 are connected to each other, the suction will cause the ball 273 inside to collide with each other under the airflow when passing through the vibration stabilizing box 271, further enhancing the irregularity of vibration.

[0070] After the adsorption component 28 completes the adsorption of the back of the keyboard, this multi-state vibration effect is precisely transmitted to the keyboard body through the vibration guide block 276, so that dust and debris hidden deep in the keyboard crevices and hard to reach are separated from the keyboard surface under the action of vibration (including subsequent polyethylene particles), reducing the difficulty of subsequent cleaning.

[0071] Furthermore, this vibration will not damage the keyboard.

[0072] On the one hand, the vibration generated by the device (the device in this solution refers to the computer keyboard cleaning device) is a slight vibration. The vibration is generated by the suction force generated by the exhaust fan 22. After the energy conversion and transmission of components such as the resonant ball string 262, the ball 273, the vibration guide rod 274 and the vibration concentration cover 275, the vibration is finally transmitted to the keyboard.

[0073] On the other hand, the keyboard is effectively fixed and supported during cleaning through the adsorption component 28 and the stabilizing component 29. The rubber ring 282 of the adsorption component 28 can buffer vibration stress, and the spring rod 292 and roller 294 of the stabilizing component 29 can disperse vibration and prevent stress concentration, thereby ensuring that the keyboard can be cleaned under vibration in a stable state without being damaged.

[0074] Step 2: After the vibration mechanism 2 completes the adsorption and fixation of the keyboard and the transmission of vibration, the electro-hydraulic rod 25 begins to extend, so that the usable surface of the keyboard is close to the cleaning box 31 of the cleaning mechanism 3. At this time, the controller controls the pressurizer 41 in the cleaning mechanism 4 to draw in and compress the outside air, so as to fully mix the polyethylene particles stored in the pressurization box with the air to form a pressurized particle flow with a certain pressure (the mixture of polyethylene particles and air is called: pressurized particle flow). Driven by the pressure difference, this pressurized particle flow flows into the collection box 374 along the feed pipe 375. The collection box 374 can distribute the pressurized particle flow to the two transfer pipes 355 and finally deliver it to the pressure box 351 of the stirring and electrostatic assembly 35.

[0075] When the pressurized particle stream enters the pressure chamber 351, the electrostatic discharge rod 352 applies electrostatic charge to the surface of the polyethylene particles in the pressurized particle stream based on the principle of electrostatic adsorption, enabling the polyethylene particles to adsorb dust and debris. At the same time, the rotating rod 353's built-in motor is also started synchronously, thereby driving the rotating rod 353 to rotate. As the rotating rod 353 rotates, the stirring rack 354 set in the rotating rod 353 stirs the polyethylene particles, making the polyethylene particles fully tumble and mix in the chamber. This greatly improves the coverage of the electrostatic discharge rod 352 applying electrostatic charge to the polyethylene particles, ensuring that each polyethylene particle can be evenly charged with electrostatic charge, laying a solid foundation for subsequent cleaning work.

[0076] As the pressurized particle stream is continuously input into the pressure chamber 351, the air pressure inside the pressure chamber 351 gradually increases. When the pressure sensor inside the pressure chamber 351 detects (the pressure sensor detection is existing technology, so it is not shown in the figure) that the air pressure reaches the preset release value of the discharge assembly 36 (this value is customized by the operator according to the material and volume of the keyboard), the pressure sensor will then send feedback information to the controller. The controller will control the hydraulic gate 363 to drop, thereby causing the discharge gate 362 to lose the obstruction of the hydraulic gate 363. Under the action of the pressure difference, the pressurized particle stream quickly opens the discharge gate 362 and enters the arc-shaped multi-hole spray block 32 through the fixed frame 361. Because the arc-shaped multi-hole spray block 32 is semi-arc, the spray holes directly face the keyboard's usage surface, spraying the pressurized particle stream onto the keyboard's usage surface in the form of a spray, allowing the particles to penetrate into every crevice and corner of the keyboard. They use their own electrostatic charge to adsorb dust and debris, achieving a highly efficient cleaning effect.

[0077] Step 3: During the cleaning process, the used polyethylene particles will naturally sink into the recycling bin 33 inside the cleaning box 31 under the action of gravity and airflow. At this time, the suction force generated by the first suction pump 372 of the input / output component 37 will suck out the polyethylene particles in the recycling bin 33 through the suction pipe 34 and stably transport them to the cleaner 42 along the discharge pipe 373. This is the prior art, similar to the particle cleaning equipment in the prior art in industry. It can use water flow or other cleaning media to clean the impurities adsorbed on the surface of the polyethylene particles. After cleaning, the polyethylene particles are transferred to the dryer 43 under the action of the vacuum filter set in the cleaner 42. The dryer 43 uses the heat generated by the heating element to quickly evaporate the moisture on the surface of the particles and restore them to a dry state. Finally, the dried polyethylene particles return to the pressurizer 41 through the synergistic action of the inner rib pipe 44 and the second suction pump 45, completing the entire keyboard cleaning process.

[0078] When polyethylene particles enter the inner ribbed pipe 44 from the dryer 43, the ribbed structure inside the inner ribbed pipe 44 obstructs and diverts the polyethylene particles. On the one hand, when the polyethylene particles move along the pipe under the suction of the second suction pump 45, they will continuously collide and rub against the ribs. This collision and friction causes the particles that are stuck together to gradually loosen and separate under the action of mechanical force. On the other hand, the airflow in the inner ribbed pipe 44 forms a complex flow field under the guidance of the ribs, generating local airflow vortices and velocity differences. These uneven airflows can exert forces of different directions and magnitudes on the stuck particle clusters, further promoting the particle clusters to disperse. This effectively avoids the polyethylene particles from sticking together after drying and affecting subsequent recycling, ensuring that the particles can re-enter the pressurizer 41 in a relatively dispersed and independent state.

[0079] It should be noted that during the cleaning process, the operator continuously observes the keyboard surface and the inside of the cleaning box 31. When there is no longer obvious dust, stains, or debris on the keyboard surface, and the amount of newly collected dust and debris in the recycling bin 33 of the cleaning box 31 is significantly reduced to almost none, this is used as the basis for judgment. For example, if no impurities are seen on the surface of the polyethylene particles newly entering the recycling bin 33 during several minutes of continuous cleaning operations, it indicates that most of the contaminants on the keyboard surface have been removed. The operator will then shut down the equipment via the controller. At this time, the electric slider 23 will drive the connected electro-hydraulic rod 25, resonance component 26, vibration transmission component 27, and adsorption component 28 to bring the keyboard back close to the inlet 211. If the exhaust fan 22 is turned off, the operator will then remove the cleaned keyboard from the inlet 211 and place the next keyboard to be cleaned back in the inlet 211. Then the controller will start the equipment, and the equipment will repeat the above cleaning process.

[0080] It should be noted that the electric slider 23 stopping near the inlet 211, the extension distance of the hydraulic rod in the adsorption assembly 28, the adsorption of the keyboard after it is placed in the inlet 211, and other simple controls are all mature existing control technologies, and will not be elaborated here.
