Specification

Description:Field of the Invention


The present disclosure generally relates to aerosol delivery systems. Further, the present disclosure particularly relates to an aerosol delivery system comprising a micro-dispenser and a permeable medium.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Aerosol delivery systems have been extensively utilized across various industries. Such systems are widely employed for the efficient delivery of aerosolized substances in applications such as inhalers, air fresheners, and other personal care products. Aerosol delivery systems typically include a mechanism for atomizing a liquid substance into fine particles, enabling effective dispersion in the air. Conventional systems typically employ a propellant or pressurized gas to force the aerosol-forming substance through a nozzle or atomizer to create a fine mist or spray. These systems often rely on a simple valve mechanism to control the flow of the substance, which is released into the atmosphere or a targeted area.
However, conventional aerosol delivery systems are associated with several limitations. A common drawback is the reliance on propellants that are not environmentally friendly, such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs), which contribute to ozone layer depletion and global warming. Furthermore, the efficiency of such systems in controlling the quantity and consistency of the aerosol released is often compromised. Traditional aerosol dispensers are known to produce uneven atomization, leading to inconsistent particle sizes in the aerosol cloud. Such inconsistency can impact the effectiveness of the aerosol delivery, particularly in applications where uniform particle size distribution is critical, such as in medical inhalers or precision spray devices. Additionally, conventional systems may face challenges related to clogging or leakage of the aerosol-forming substance, particularly when the substance is viscous or contains particulate matter.
In recent years, there has been a shift towards systems that use mechanical or electronic means to atomize the aerosol-forming substance without the need for a propellant. For example, some systems employ piezoelectric or ultrasonic elements to generate high-frequency vibrations that break down the liquid substance into fine droplets. While such systems address environmental concerns associated with propellants, they introduce other challenges. Piezoelectric and ultrasonic atomizers require precise control mechanisms to ensure consistent operation, and they are often susceptible to performance degradation due to wear and tear of the vibrating elements. Moreover, such systems tend to be energy-intensive, requiring a significant power supply for continuous operation, which limits their application in portable or battery-operated devices.
Another common approach involves using air pumps or manual mechanisms to create a vacuum for drawing the aerosol-forming substance into an atomizing chamber. Such systems are generally simpler and do not rely on external power sources or complex electronic components. However, manually-operated systems often suffer from limitations in maintaining a consistent airflow rate, which affects the uniformity of aerosol generation. Additionally, these systems may require considerable physical effort, making them less convenient for continuous or frequent use, particularly in medical applications where a steady and controlled dose of medication is required.
Further advancements in aerosol delivery technologies have incorporated heating elements to facilitate the vaporization of the aerosol-forming substance. By applying heat to the substance, such systems are able to generate an aerosol without the need for mechanical atomization or propellant gases. Heated aerosol delivery systems have gained popularity in the context of nicotine delivery devices, such as electronic cigarettes. These systems typically use a heating coil or plate to vaporize a liquid containing nicotine and other flavoring agents. However, a key drawback associated with heated aerosol systems is the difficulty in maintaining a consistent temperature across the heating element, which can lead to uneven vaporization and affect the quality of the aerosol produced. Furthermore, the direct exposure of the aerosol-forming substance to the heating element may result in the formation of harmful byproducts due to thermal degradation of the substance.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for aerosol delivery, including issues related to environmental sustainability, consistent aerosol generation, clogging or leakage, and power consumption.

FIG. 1 illustrates an aerosol delivery system (100), in accordance with the embodiments of the present disclosure. In an embodiment, the aerosol delivery system (100) includes a micro-dispenser (102) positioned within a containment chamber (104). The micro-dispenser (102) is responsible for drawing an aerosol-forming substance from a source contained within or external to the system (100). Said micro-dispenser (102) comprises a suction diaphragm (106) designed to create a vacuum. The suction diaphragm (106) operates by moving in response to an applied force, causing a decrease in pressure inside the micro-dispenser (102), which in turn draws the aerosol-forming substance into the chamber. The diaphragm (106) is structured to withstand repeated cycles of expansion and contraction without degrading, ensuring the continuous intake of the substance.

The arrangement of the permeable medium (110) within the system (100) is critical for ensuring efficient aerosol generation, as it allows for maximum interaction between the airflow, the substance, and the heat source.
In an embodiment, the aerosol delivery system (100) includes a suction diaphragm (106) that is flexibly interfaced with a biasing spring element. Said interfacing allows the suction diaphragm (106) to respond dynamically to changes in pressure created during the inhalation process. When the user inhales, the biasing spring element assists the suction diaphragm (106) in creating a more effective vacuum within the micro-dispenser (102), enabling the aerosol-forming substance to be drawn efficiently into the system (100). The biasing spring element works in coordination with the flexible diaphragm, allowing for controlled movement while maintaining structural integrity during repeated cycles of inhalation. The spring element may be made from resilient materials such as stainless steel or specialized polymers to ensure long-term durability and reliable performance under various environmental conditions. By interfacing with the suction diaphragm (106), the spring element provides a consistent force that enhances the diaphragm's capacity to create a vacuum. This results in the improved transfer of the aerosol-forming substance from the source into the system (100).
In an embodiment, the conduit assembly (108) of the aerosol delivery system (100) is integrally structured with a spiral reinforcement element. Said spiral reinforcement element is interwoven along the longitudinal axis of the conduit assembly (108) and provides additional strength and flexibility to the conduit, particularly during the transmission of the aerosol-forming substance. The spiral reinforcement is typically made from materials such as metal wire or reinforced polymers that prevent the conduit from collapsing under pressure while maintaining the necessary flexibility for substance flow. By being interwoven throughout the length of the conduit assembly (108), the spiral reinforcement ensures that the structure remains stable and resistant to kinking or deformation, which could otherwise disrupt the substance flow toward the permeable medium (110). This reinforcement also helps to minimize internal resistance within the conduit, reducing the pressure drop and ensuring that the aerosol-forming substance reaches the permeable medium (110) with minimal loss of efficiency. The integration of the spiral reinforcement element provides enhanced durability and performance under varying operational conditions.
In an embodiment, the valve unit (112) of the aerosol delivery system (100) is hingedly anchored to a pivot pin positioned adjacent to the conduit assembly (108).

The hinged connection facilitates smooth and controlled movement of the valve unit (112), ensuring consistent flow control even during rapid adjustments. The materials used for the pivot pin and hinge mechanism may include corrosion-resistant metals such as stainless steel or alloys to provide durability and smooth operation over an extended period of use. The placement of the valve unit (112) along the conduit assembly (108) allows for easy access and control, ensuring that the flow of the aerosol-forming substance is managed accurately without requiring complex mechanisms.
In an embodiment, the permeable medium (110) of the aerosol delivery system (100) is radially aligned with a series of micro-channels formed on the inner surface of the conduit assembly (108). Said radial alignment is designed to facilitate the even distribution of the aerosol-forming substance as it passes from the conduit assembly (108) into the permeable medium (110). The micro-channels are structured to guide the substance along predefined pathways, ensuring that the substance reaches all areas of the permeable medium (110) uniformly. This uniform distribution is critical for the efficient generation of aerosol, as it allows the entire surface of the permeable medium (110) to be used effectively. The micro-channels may vary in size and density depending on the specific properties of the aerosol-forming substance, such as viscosity or particle size, to optimize substance flow and aerosol generation. The radial alignment of the permeable medium (110) with the micro-channels also prevents clogging or over-saturation in specific areas, thereby enhancing the overall performance of the system (100).
In an embodiment, the heating element of the aerosol delivery system (100) is transversely situated relative to the permeable medium (110), establishing a direct thermal pathway. Said transverse positioning is intended to maximize heat transfer efficiency by ensuring that the heat generated by the heating element is uniformly distributed across the permeable medium (110). The direct thermal pathway allows the aerosol-forming substance to be rapidly heated as it passes through the permeable medium (110), enabling immediate aerosol generation. The heating element may be constructed from materials with high thermal conductivity, such as ceramic or metal alloys, to provide consistent and reliable heat transfer. The transverse arrangement also prevents excessive heat buildup in specific areas of the permeable medium (110), which could otherwise lead to degradation or inconsistent aerosol production. By positioning the heating element in this manner, the system (100) ensures that the aerosol-forming substance is converted into aerosol particles efficiently and consistently during operation.
In an embodiment, the micro-dispenser (102) of the aerosol delivery system (100) further includes a calibrated plunger interfacing with the suction diaphragm (106).

The check valve assembly includes one or more valves designed to allow the substance to flow in a single direction, ensuring that the substance is consistently delivered to the permeable medium (110) without the risk of reverse flow. The check valve assembly is typically made from materials compatible with the aerosol-forming substance, such as stainless steel or durable polymers, to provide long-lasting performance. The placement of the check valve assembly within the conduit assembly (108) helps to maintain the pressure balance within the system (100), preventing any interruptions in substance delivery. The check valve assembly interacts with the other components of the micro-dispenser (102) to ensure smooth and efficient operation during the aerosol delivery process.
FIG. 2 illustrates sequential diagram of an aerosol delivery system (100), in accordance with the embodiments of the present disclosure. The illustrated figure depicts an aerosol delivery system (100) where the user initiates the process by inhaling. This activates a micro-dispenser (102) housed within a containment chamber (104). The micro-dispenser (102) uses a suction diaphragm (106) to create a vacuum that draws the aerosol-forming substance. The substance is then directed into a conduit assembly (108), which transmits it toward a permeable medium (110). A valve unit (112), intersecting the conduit assembly (108), controls the flow of the substance, regulating the passage as it moves further into the system. Once the substance reaches the permeable medium (110), a heating element heats the medium, generating aerosol. The generated aerosol is then delivered back to the user through the airflow passage, completing the system's cycle.
In an embodiment, the aerosol delivery system (100) includes a micro-dispenser (102) positioned within a containment chamber (104), where the micro-dispenser (102) operates with a suction diaphragm (106). The suction diaphragm (106) creates a vacuum that draws the aerosol-forming substance into the micro-dispenser (102). Said suction diaphragm (106) operates by forming a pressure differential, allowing for effective inhalation-based activation of the system. The vacuum mechanism allows for controlled substance intake without requiring external pressure sources. The diaphragm's flexible material allows for repeatable motion cycles while maintaining structural integrity, making it ideal for consistent operation. The interaction between the suction diaphragm (106) and the containment chamber (104) enables efficient movement of the aerosol-forming substance toward downstream components, such as the conduit assembly (108). This system architecture minimizes leakage risks and improves the control of the aerosol-forming substance, ensuring that the substance is delivered accurately into subsequent system components for processing and eventual aerosol generation.
In an embodiment, the suction diaphragm (106) of the aerosol delivery system (100) is flexibly interfaced with a biasing spring element. Said biasing spring element allows the suction diaphragm (106) to respond dynamically to inhalation forces by enhancing its return movement after displacement. This interfacing arrangement enables the diaphragm (106) to return to its neutral position quickly, ready for the next inhalation cycle, thereby maintaining a continuous flow of the aerosol-forming substance into the system. The biasing spring element provides a consistent counterforce, which enhances the vacuum creation process, improving the intake efficiency of the aerosol-forming substance. The flexibility of the spring element is selected to complement the diaphragm's material properties, providing smooth yet controlled displacement. The spring element also adds durability by preventing overextension of the diaphragm, thereby extending the operational life of both the diaphragm (106) and the micro-dispenser (102). The synergy between the suction diaphragm (106) and the biasing spring ensures reliable vacuum generation over repeated cycles.
In an embodiment, the conduit assembly (108) of the aerosol delivery system (100) is structured with an integrally configured spiral reinforcement element. Said spiral reinforcement element is interwoven along the longitudinal axis of the conduit assembly (108), providing enhanced structural integrity. This reinforcement prevents the conduit from collapsing under vacuum pressure during substance transmission. The spiral structure adds flexibility while maintaining the necessary rigidity, allowing the conduit to withstand both internal and external stresses. Additionally, the spiral reinforcement minimizes the risk of kinks or bends in the conduit, ensuring that the aerosol-forming substance flows smoothly through the conduit toward the permeable medium (110). The conduit assembly (108) is thus optimized for handling varying pressures and fluid dynamics within the system, reducing turbulence and resistance. The spiral reinforcement also enhances the longevity of the conduit by protecting it from mechanical wear or fatigue, especially under repeated cycles of use, ensuring consistent delivery of the aerosol-forming substance to the permeable medium (110).
In an embodiment, the valve unit (112) of the aerosol delivery system (100) is hingedly anchored to a pivot pin adjacent to the conduit assembly (108). Said pivot pin allows the valve unit (112) to rotate, providing precise modulation of the substance flow through the conduit assembly (108). The rotational engagement of the valve unit (112) facilitates fine control over the opening and closing of the conduit, allowing incremental adjustments to the flow rate of the aerosol-forming substance. This hinged configuration ensures that the valve unit (112) can operate with minimal friction, reducing wear on the components and maintaining consistent performance over time. The placement of the pivot pin near the conduit assembly (108) allows for easy actuation of the valve unit (112), ensuring that flow control is both responsive and reliable. The valve's rotational design minimizes disruptions to the substance flow, preventing pressure surges or blockages that could otherwise affect the system's operation.
In an embodiment, the permeable medium (110) of the aerosol delivery system (100) is radially aligned with a series of micro-channels formed on the inner surface of the conduit assembly (108). Said radial alignment facilitates the even distribution of the aerosol-forming substance as it transitions from the conduit assembly (108) into the permeable medium (110). The micro-channels act as directed pathways for the substance, preventing clumping or uneven flow, which could negatively affect aerosol generation. The radial configuration ensures that the substance is uniformly absorbed by the permeable medium (110), optimizing the interaction between the substance and the airflow passing through the system. This alignment enhances the overall efficiency of aerosol generation by ensuring that the maximum surface area of the permeable medium (110) is utilized. The arrangement of the micro-channels also prevents the permeable medium (110) from becoming oversaturated in localized areas, which could otherwise lead to clogging or inconsistent aerosol output.
In an embodiment, the heating element of the aerosol delivery system (100) is transversely situated relative to the permeable medium (110), creating a direct thermal pathway. Said transverse positioning allows for rapid heat transfer from the heating element to the aerosol-forming substance within the permeable medium (110). The direct thermal pathway ensures that the substance is heated uniformly, enabling immediate aerosol generation without delays. By situating the heating element transversely, the system minimizes energy loss and focuses the heat on the permeable medium (110), allowing for efficient aerosol production. The transverse arrangement also prevents localized overheating, which could degrade the permeable medium (110) or the substance. This configuration is particularly effective in maintaining a consistent aerosol output, as the heating element can quickly bring the substance to the desired temperature for aerosolization while avoiding thermal stress on the surrounding components.
In an embodiment, the micro-dispenser (102) of the aerosol delivery system (100) includes a calibrated plunger interfacing with the suction diaphragm (106).
