Description

Technical Field

[0001] The present invention relates to the technical field of oral medical equipment, and in particular to an integrated device and system for plasma in-situ cleaning and care of removable dentures. Background Art

[0002] At present, the cleaning and maintenance of removable dentures mainly rely on two methods: traditional physical brushing and chemical soaking. The physical brushing method usually requires the user to hold a soft-bristled brush and use a special cleaning agent to repeatedly scrub the denture surface. This method is not only time-consuming and labor-intensive, but also difficult to effectively clean the gaps and dead corners of the complex structure of the denture clasp and base tissue surface, which can easily lead to bacterial residue. Long-term use may also cause wear on the denture surface due to uneven brushing force. Chemical soaking is to soak the denture in a cleaning solution containing chlorine and peroxide. Although it can dissolve dirt to a certain extent, it is easy to corrode the denture material if the soaking time is too long, affecting its service life. At the same time, chemical residues may irritate the oral mucosa and cause allergic or inflammatory reactions. In addition, existing denture cleaning equipment generally has the problems of single function and low intelligence. It lacks visual monitoring and precise control of the cleaning process, and cannot provide personalized cleaning solutions based on the usage status and dirt level of the denture, making it difficult to meet users' needs for efficient, safe and convenient cleaning methods. With the increasing application of plasma technology in the medical field, research on its use in denture cleaning has also begun. However, existing solutions often suffer from low plasma-cleaning fluid mixing efficiency, insufficient utilization of active ingredients, and the lack of a closed-loop cleaning fluid circulation system, resulting in water waste and the risk of secondary pollution. Furthermore, traditional denture fixation methods are difficult to adapt to dentures of varying shapes and sizes, lacking adaptive gripping and electric field conduction, resulting in uneven cleaning results.

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-8 The present invention provides an integrated device for in-situ plasma cleaning and care of removable dentures, including a device cabinet 1. The top of the device cabinet 1 is provided with an upper cover 2, and the upper cover 2 is provided with a raised switch 3. A connection port 4 is provided adjacent to the raised switch 3. The interior of the device cabinet 1 is divided into an upper operation interaction area, a middle cleaning and care core area, and a lower power and control area. The upper operation interaction area includes a magnetic suction and micro switch lock, a visual bubble observation window, and a multi-mode paddle. The middle cleaning and care core area includes an elastic suspension grid 5, a venturi tube 18 nested spoiler column 21, and a cleaning chamber 7 cavity. The lower power and control area includes a U-shaped guide groove 9, a filter layer, a liquid pump 15, a plasma generator 11, a PCB board 22, and a micro relay 23. In the upper operation and interaction area, the magnetic attraction and micro-switch lock are located at the junction edge between the upper cover 2 and the cleaning chamber 7. The magnet is hidden inside the upper cover 2, and the micro-switch contacts are located at the upper edge of the cleaning chamber 7. The visual bubble observation window is a small transparent strip on the upper cover 2 or side wall, located in the non-load-bearing area in the middle of the short side wall of the cleaning chamber 7. The multi-mode paddle is a raised switch 3 on the surface of the upper cover 2 near the edge, with a corresponding micro-relay 23 below it. In the middle-level washing and care core area, the elastic suspension grid 5 is fixed to the center of the cleaning chamber 7 by a silicone bracket, with the bottom of the grid suspended 5-10mm. The elastic suspension grid 5 has metal wires for adaptively clamping dentures and conducting electric fields. The venturi tube 18 is located below the side wall of the cleaning chamber 7, near the outlet of the liquid pump 15. The spoiler column 21 is directly inserted into the output end of the venturi tube 18 and fixed by threads or a clamp. The cleaning chamber 7 is the middle-level container, enclosing all washing and care-related structures, and its inner wall is treated with a hydrophobic coating. In the lower power and control area, a U-shaped guide groove 9 is provided at the lower part of the cleaning chamber 7, and a drainage pipe 8 is connected between the U-shaped guide groove 9 and the cleaning chamber 7. The U-shaped guide groove 9 is arranged directly below the cleaning chamber 7 and aligned with the drainage hole at the bottom of the cleaning chamber 7. The filter layer is embedded in the guide groove inlet, and the liquid pump 15 has an installed liquid pump inlet 14 and a liquid pump outlet 16. The liquid pump inlet 14 is connected to the U-shaped guide groove 9 by a pump pipe 13, and the liquid pump inlet 14 is connected to the U-shaped guide groove 9 outlet. The liquid pump 15 is arranged next to the liquid pump inlet 14 and is connected to the Venturi tube 18 and the plasma generator 11 through a silicone tube. The plasma generator 11 is arranged adjacent to the air pump and is connected to the Venturi tube 18 through a pipeline to inject plasma. The PCB board 22 and the micro relay 23 are arranged in the corner area of ​​the device, away from the liquid area, and the paddle, liquid pump 15, and plasma generator 11 are connected by wiring to realize signal control.

[0034] It also includes a fixed bracket 6, which is used to install and fix the suspended grid 5 so that the suspended grid 5 is stably located in the central position inside the cleaning chamber 7. The U-shaped guide trough 9 is connected to the plasma generator 11 through the silicone connecting tube 10 between the U-shaped guide trough and the plasma generator, the plasma generator 11 is connected to the liquid pump 15 through the silicone connecting tube 12 between the plasma generator and the liquid pump, and the venturi tube 18 is connected to the U-shaped guide trough 9 through the silicone connecting tube 17 between the venturi tube and the U-shaped guide trough. A through pipe 19 is provided on the venturi tube 18 for assisting in the transmission of fluid, and the through pipe 19 is fixedly installed by installing a clamping ring 20. The visual bubble observation window corresponds to the observation port 25 and the glass strip 26 provided on the device. The glass strip 26 is installed at the observation port 25 for observing the state of bubbles and water flow. The suspended grid 5 is assisted in installation by a magnetic mounting assembly 24. The magnetic mounting assembly 24 cooperates with the corresponding structure in the device cabinet 1 to achieve convenient installation and fixation of the suspended grid 5.

[0035] When the device is activated, the lower power zone is activated first: liquid pump 15 draws clean cleaning fluid, purified by the filter layer, from the U-shaped diversion trough 9 via pump tube 13. Manual refill is required through connection port 4 for the first use. The cleaning fluid then flows rapidly into the middle venturi tube 18. The venturi tube 18 utilizes the "throat effect" to create negative pressure in the constricted section, drawing plasma generated by the plasma generator 11, such as oxygen-containing active particles, into the fluid. At this point, a disruptor column 21, nested at the output end of the venturi tube 18, disrupts the fluid flow through its unique geometry, breaking large bubbles into microbubbles. These microbubbles act as "active carriers," carrying the plasma's active components, hydroxyl radicals (OH) and ozone (O3), which fuse deeply with the cleaning fluid to form "plasma-activated water." The activated water is then piped to the middle cleaning chamber 7. The elastic suspension grid 5, already coordinated with the fixed bracket 6 via the magnetic mounting assembly 24, adaptively clamps the removable denture, wrapping the clasp and base of the metal wires as they elastically deform. The suspended grid 5 is not only a "clamp", but also an "electric field conductor" - its metal wires connect the lower PCB board 22 and the electric field constructed by the plasma generator 11, allowing the plasma energy to evenly cover the denture surface, achieving the dual effects of "electric field + activated water": the energy released when the microbubbles burst impacts denture dirt such as pigments and plaque, and the active particles chemically decompose stubborn organic matter, completing the "physical stripping + chemical degradation" collaborative cleaning. The cleaning waste liquid flows into the drain pipe 8 through the drainage hole at the bottom of the cleaning chamber 7, and then into the lower U-shaped guide groove 9. The microporous ceramic / nylon material of the filter layer in the U-shaped guide groove 9 intercepts impurities, food residues, and fallen old adhesives. The purified liquid is pumped out again by the liquid pump 15 through the liquid pump inlet 14, forming a "closed-loop reflux of cleaning liquid" until the washing process is completed. The upper-level operation interaction area cooperates throughout the process: the multi-mode paddle of the raised switch 3 triggers the micro-relay 23 to accurately adjust the power of the liquid pump 15 and the start and stop time of the plasma generator 11, realizing the "gentle cleaning with low power and short plasma injection" and "deep cleaning with high power and long activation" mode switching; the glass strip 26 of the observation port 25 allows the user to intuitively observe the microbubble density and water flow shape in the cleaning chamber 7, and provide real-time feedback on the cleaning status; the magnetic attraction and micro switch lock ensure that the device is not started until the upper cover 2 is closed in place, avoiding the risk of accidental touch.

[0036] Example 2: A removable denture plasma in-situ cleaning and care integrated system, using the removable denture plasma in-situ cleaning and care integrated device according to any one of claims 1 to 9, through the coordinated cooperation of various structures, to construct a complete in-situ cleaning and care system, including the following modules:

[0037] 1. Denture clamping and electric field conduction module: The elastic suspension grid 5 in the middle cleaning and protection core area is used to adaptively clamp the removable denture. The electric field is conducted by the grid metal wire, so that the plasma acts evenly on the denture surface.

[0038] 2. Microbubble refinement and active mixing module: Through the structure of the venturi tube 18 nested with the spoiler column 21 in the middle cleaning core area, the bubbles in the fluid are refined, the mixing effect of the plasma active material and the cleaning fluid is enhanced, and the cleaning power is improved;

[0039] 3. Cleaning liquid circulation and waste liquid separation module: Relying on the design of the U-shaped guide groove 9 + microporous filter layer in the lower power and control area, the liquid discharged from the cleaning chamber 7 is separated into waste liquid, and the filtered cleaning liquid is returned to the Venturi tube 18 structure through the liquid pump 15 in a closed loop, realizing the recycling of the cleaning liquid;

[0040] 4. Multi-mode control and operation safety module: Utilizing the paddles in the upper operation interaction area in conjunction with micro-relays 23, multi-mode control switching is achieved to meet different washing and care needs. A magnetic attraction and micro-switch lock provide an anti-accidental touch safety protection mechanism to ensure user operation safety.

[0041] 5. Status Visualization Monitoring Module: Relying on the quartz glass observation strip 25 and glass strip 26 in the upper operation interaction area, the module visualizes the status of bubbles and water flow, allowing users to intuitively understand the cleaning process and enhance the system's user experience and monitorability.

[0042] The system utilizes "layered collaboration + cross-layer linkage" to build a complete closed-loop cleaning and care system. The upper layer of the operation layer serves as the "command center." The raised switch 3 serves as the entry point for human-machine interaction, converting user requests, such as mode selection, into electrical signals, which are then transmitted via a micro-relay 23 to the lower PCB board 22 of the control layer. The observation port 25 and glass strip 26 form a "status feedback chain," allowing users to grasp the operational details of the core cleaning and care area in the middle layer in real time, forming an interactive closed loop of "operation-observation-adjustment." The middle layer of the execution layer serves as the "cleaning and care battlefield." The elastically suspended grid 5 solves the challenges of "adaptive denture fixation + electric field conduction." The Venturi tube 18 and spoiler column 21 achieve "microbubble refinement + active ingredient mixing." The cleaning chamber 7 provides a "closed cleaning and care space + hydrophobic anti-corrosion protection." These three elements work together to precisely apply the cleaning power of "activated water + electric field" to the denture, achieving "in-situ, efficient cleaning and care." The lower layer of the power layer is the "energy engine": the liquid pump 15 drives the circulation of the cleaning liquid, the plasma generator 11 produces active particles, the U-shaped guide groove 9 and the filter layer ensure "waste liquid purification + closed-loop reflux", and the PCB board 22 and the micro relay 23 are like "nerve networks", receiving upper-level instructions and dispatching lower-level power, allowing the entire system to operate on demand. For example, when switching modes, the liquid pump power and plasma injection amount are adjusted synchronously.

[0043] In this invention, the device cabinet 1 provides physical support and protection for the entire unit. When the upper cover 2 is closed, the magnet and microswitch lock function dually: the magnet, hidden inside the upper cover 2, adheres to the magnetic surface at the top edge of the cleaning chamber 7, achieving physical locking; the microswitch contacts are embedded in the upper edge of the cleaning chamber 7. Only when the magnet is fully closed and the upper cover 2 is in place does the circuit conduct, ensuring safe operation. At this point, the elastic suspension grid 5, coupled with the fixed bracket 6 via the magnetic mounting assembly 24, is stably suspended 5-10 mm above the bottom center of the cleaning chamber 7, ready to be loaded with dentures. Fluid circulation and plasma activation: Lower power zone → middle core zone. For first-time use or refilling, the user replenishes cleaning fluid through connection port 4. After starting the device, lower-layer liquid pump 15 operates, drawing fluid from U-shaped diversion trough 9 via pump tube 13. This U-shaped diversion trough 9 is located directly below cleaning chamber 7, and the two are connected by drain pipe 8. Wastewater from cleaning chamber 7 flows through drain pipe 8 into U-shaped diversion trough 9. The microporous structure of the filter layer within the trough intercepts impurities such as food residue from dentures and debris from old adhesive, ensuring the purity of the fluid entering liquid pump 15. Liquid pump 15 pressurizes the cleaning fluid and delivers it through liquid pump outlet 16 and silicone tubing to middle-layer Venturi tube 18. The Venturi tube 18 utilizes the "throat effect" to cause a sudden increase in fluid velocity and a sudden drop in pressure at the constricted section, creating a negative pressure zone. This negative pressure, through pipelines such as the U-shaped flow channel and the plasma generator's silicone connecting tube 10, draws ionized gas plasma from the plasma generator 11. The plasma generator 11 relies on an air pump (not shown) to provide the necessary gas source. Through dielectric barrier discharge, the air / inert gas is ionized into a plasma containing hydroxyl radicals (OH) and ozone (O3) active species. A spoiler 21 is fixed to the output end of the Venturi tube 18 via threads or a retaining ring. The flow creates turbulence, breaking large bubbles into microbubbles. This allows the plasma active species to deeply mix with the cleaning fluid, forming "plasma-activated water." This water is then adjusted through a through-tube 19, with optional external air supply, to optimize the bubble composition before being injected into the cleaning chamber 7. Denture cleaning and care is performed in the middle core area: removable dentures are placed on an elastically suspended mesh frame 5. The mesh, resiliently deformed by metal wires, adaptively wraps around the denture's clasp, base, and artificial teeth, enabling "tool-free, quick clamping." Simultaneously, the metal wires act as a conductive medium, connecting the underlying PCB 22 with the electric field generated by the plasma generator 11, ensuring that plasma energy evenly covers the denture surface. "Plasma-activated water" flows into the cleaning chamber 7, where microbubbles adhere to the denture surface. Surface tension and the electric field rupture the bubbles, releasing energy like shock waves that physically remove dirt, such as plaque biofilms and pigment deposits. Hydroxyl radicals and ozone-activated particles chemically decompose organic matter, such as protein stains and bacterial cell membranes, achieving a synergistic "physical impact + chemical degradation" cleaning process. During the cleaning process, a hydrophobic coating, such as polytetrafluoroethylene, on the inner wall of the cleaning chamber 7 accelerates the shedding of waste liquid, preventing residual corrosion of the device.Waste liquid circulation and intelligent control: Lower power zone + upper interaction zone: After cleaning, waste liquid flows back through the drainage holes at the bottom of the cleaning chamber 7 and drain pipe 8 to the U-shaped diversion channel 9, repeating the "filtration-extraction-activation-cleaning" closed loop until the set cleaning time is completed. The upper operation interaction zone fully coordinates the entire process: the multi-mode paddle on the raised switch 3 triggers the micro-relay 23, sending instructions to the PCB 22, precisely controlling the power of the liquid pump 15. For example, "gentle mode" reduces flow rate, "deep mode" increases pressure, and the start and stop time of the plasma generator 11 controls the concentration of active particles. The glass strip 26 of the observation port 25 is made of quartz glass, which is resistant to corrosion from activated water, allowing the user to intuitively observe the microbubble density and water turbulence patterns in the cleaning chamber 7, providing real-time feedback on the cleaning status, and completing the "operate-monitor-adjust" human-machine interactive closed loop. The integration of plasma activation, microfluidic venturi tube + spoiler column, adaptive clamping, closed-loop circulation and other technologies breaks through the bottleneck of traditional denture cleaning "low efficiency, high risk of damage, and reliance on manual intervention", providing a new technical path for oral care equipment.

Any modifications, replacements, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
