Description

Attorney Docket No.: 134357-0001 WOO 1DUAL VAPOR DELIVERY DEVICE AND SYSTEMTECHNICAL FIELD

[0001] The embodiments described herein are generally directed to electronic vaporizer products for delivering inhalation media, and, more particularly, to a device and system for dual vapor delivery.BACKGROUND

[0002] Personal vaporizers are a popular alternative to traditional substance and tobacco leaf-based cigarettes that must be combusted in order to generate smoke for inhalation. Personal vaporizers provide vapor for inhalation, but do not produce certain byproducts of combustion that may be harmful to human health. Personal vaporizers are electronic inhalers that vaporize or atomize a liquid solution into an aerosol that may then be inhaled by the user. A typical vaporizer has two main parts, a device and a cartridge. The device typically contains a battery and control electronics. The cartridge typically contains the liquid to be atomized and an atomizer. A limitation of most devices is that only one cartridge can be used with a device at a time. Some users desire more vapor than can be provided via a single cartridge. Some users want to inhale combinations of liquids from different cartridges at the same time. Although some devices exist that allow for the use of two cartridges simultaneously, they do not meet the needs of the users. They do not provide a convenient solution for using cartridges simultaneously. They also allow too much air to flow through the cartridges, creating an undesirably low resistance to inhalation, making it difficult for the user to inhale, negatively impacting vapor production, and making any sensor in the device less likely to activate. The invention addresses these shortcomings.SUMMARY

[0018] FIG. 1 illustrates an electronic vaporizer device 100, according to an embodiment. In an embodiment, an electronic vaporizer device 100 is disclosed, comprising a cover 110 which can serve as a housing and can delineate and / or attach to a body 105 for electronic vaporizer device 100. Body 105 can include two or more cartridge receptacles 120A, 120B, in fluid communication with each other. Cover 110 can attached and / or engage to the body so as to cooperate with the body to form an internal airtight cavity 115 surrounding the cartridge receptacles 120 A, 120B. Airtight cavity 115 can be isolated from an electronic control unit 165 by an internal wall in body 105 and configured so that air enters only through one or more defined air inlets 102. Air inlets 102 can be located in the walls of body 105 or in the wall separating electronic control unit 165 from airtight cavity 115.

[0019] Further, electronic vaporizer device 100 can comprise one or more seals, which can include an outer cover seal 125 and an inner cover seal 130 that interlock with each other thereby forming a continuous airtight combined aerosol channel 135 when engaged with body 105, and a mouthpiece 140 attached and / or connected to cover 110, including a vapor outlet 145 that connects and / or is in fluid communication with the continuous airtight combined aerosol channel 135. Moreover, two or more cartridges 150A and 150B can be disposed or introduced within cartridge receptacles 120A and 120B. Cartridges 150A and 150B can have4134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 each a substance to produce vapor when heated by a heating element 160. A vapor can include any substance in its gaseous state. An aerosol can include an substance of solid or liquid particles suspended in a gas, including recondensed vapor. For purposes of this patent, vapor may be used more broadly to refer to either a substance in its gaseous state or an aerosol.. Additionally, electronic vaporizer device 100 can comprise an airflow pathway. Airflow inlet 102 can be connected to internal airtight cavity 115, wherein the airflow intake allows the air intake to flow into the continuous airtight combined aerosol channel 135 via the internal airtight cavity 115. When cartridges 150 are present, the air intake can flow from air inlet 102 into airtight cavity 115, and then into a cartridge 150 airflow pathway consisting of primary air channel inlet 225 and flowing the air into the continuous airtight combined aerosol channel 135. Also, electronic vaporizer device 100 can comprise an electronic control unit 165 including a controller 300, a power source 170 electrically coupled to heating element 160 wherein power source 170 provides power to heating element 160, a user interface 185 comprising at least one control such as a button 175 configured to activate and / or adjust the power transmitted to heating element 160, and an airflow sensor 180 configured to activate the heating element 160when the air intake or change in pressure is detected, wherein controller 300 is in communication with power source 170, user interface 185, and airflow sensor 180. Further, electronic vaporizer device 100 may comprise one or more airflow block seals 200.

[0020] The electronic vaporizer device 100 can be designed to enable users to vaporize and inhale substances with improved control, efficiency, and customization. By incorporating multiple cartridge receptacles 120A, 120B within an airtight cavity 115, the device 100 can allow simultaneous or selective operation of two cartridges 150, enabling blending of different formulations or maximizing vapor output. The combined vapor pathway 135 ensures that aerosol streams merge into a single, consistent flow delivered through the mouthpiece 140. An electronic control unit 165 manages power delivery and can respond to both user input and inhalation detection, providing precise activation of the heating elements 160 while maintaining stable vapor quality. The sealed airflow design minimizes leakage, enhances vapor production, and ensures that inhalation reliably triggers the device 100. This functionality can support diverse applications, including recreational use of cannabis, medical delivery, nicotine or tobacco extract vaporization, flavorings, terpenes, humectants, and / or wellness formulations, offering users a customizable and reliable inhalation experience.

[0021] The airflow inlet 102 of the electronic vaporizer device 100 can function as the primary entry point for air into the system and can be coupled to an air inlet channel that provides fluid communication with the internal airtight cavity 115. The channel may be5134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 constructed as a tube or opening, directing airflow from the inlet toward the cavity to ensure an efficient and controlled air supply. Once inside the airtight cavity, the airflow is routed toward the cartridge receptacles 120A, 120B, where it enters each cartridge’s airflow pathway and mixes with the vapor generated by the heating elements 160. The airflow can monitored by airflow sensors 180A, 180B, which detect inhalation or pressure change (through each cartridge, cavity, and / or overall airflow), and signal the electronic control unit 165 to activate the heating process. This coordinated interaction between the airflow inlet, cavity, sensors, and seals can ensure precise regulation of airflow, consistent vapor production, and reliable activation during use.

[0022] The device body 105 of the electronic vaporizer device 100 can serve as the primary structural framework that houses and supports the functional components of the system. The device body 105 can enclose the internal airtight cavity 115, which holds the cartridge receptacles 120 A, 120B, and provides structural alignment for the outer cover seal 125 and inner cover seal 130 to interlock and form the combined vapor pathway 135. The device body 105 can also provide mechanical support for the attachment of the cover housing 110 and mouthpiece 140, ensuring an airtight connection around the vapor outlet 145. Internally, the device body 105 can separate the airtight cavity from the battery compartment to protect the power supply 170 and associated charge control circuitry 195 from liquid leakage. The device body 105 can also integrate with the electronic control unit 165 and the controller 300, enabling coordinated operation with the airflow sensors 180A, 180B and airflow block seals 200A, 200B. Thus, the device body 105 can provide both mechanical integrity and functional isolation, ensuring reliable assembly and consistent vaporization performance. Additionally, the device body 105 may integrate a viewing window 205 for monitoring cartridge fluid levels and support internal light sources that illuminate the cartridges 150 during inhalation or manual activation via a control.

[0023] The cover 110 (also referred as cover housing) of the electronic vaporizer device 100 functions as a protective and structural component that retains the cartridges 150A, 150B within the cartridge receptacles 120 A, 120B and contributes to the formation of the internal airtight cavity 115 when secured to the device body 105. The cover housing 110 can incorporate the outer cover seal 125 and inner cover seal 130, which interlock to form the combined vapor pathway 135, directing aerosol from the cartridge vapor outlets 210 to the mouthpiece 140 and through the vapor outlet 145 for user inhalation. For secure attachment, the cover housing 110 may utilize magnets, snap fit, friction fit, or a latch 208 and / or combinations thereof, ensuring stability during operation for a tight fit between cover 110 and body 105, which ensures a good6134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 airtight cavity, while allowing convenient removal for cartridge replacement. In some embodiments, grip features permit the user to squeeze and slightly deform the cover to disengage snap-fit connections. By combining protective, sealing, and delivery functions, the cover housing 110 ensures reliable vapor routing, ease of maintenance, and enhanced user experience.

[0024] The internal airtight cavity 115 of the electronic vaporizer device 100 can be created when the cartridges 150A, 150B are inserted into the cartridge receptacles 120A, 120B and sealed in place by the interaction of one or more seals, which can include the outer cover seal 125, inner cover seal 130, and the cover housing 110 secured to the device body 105. This cavity can maintain controlled airflow and vaporization efficiency. During inhalation through the mouthpiece 140 and vapor outlet 145, air can be drawn into the cavity via the airflow inlet 102, which is strategically designed to ensure a predetermined flow rate or range of flow rates. Once inside, the airflow is directed toward the cartridges 150, where it flows into the cartridges 150 and mixes with the vaporized liquid generated by the heating elements 160 as they act upon the liquid contained within the liquid reservoirs 230 to form an aerosol. By ensuring that airflow consistently enters through the defined inlets and into the cartridges 150, the internal airtight cavity 115 can provide the necessary conditions for stable aerosolization and reliable vapor delivery to the user.

[0025] In one embodiment, airflow entering the internal airtight cavity 115 is fine-tuned through an airflow adjustment feature that includes an airflow adjustment slider cooperating with an air inlet seal at the air inlet control 155. The airflow inlet seal can contain an opening, while the adjustment slider includes a corresponding hole; the overlap between these holes determines the volume of airflow permitted into the cavity, and / or the resistance to airflow and thus the flow rate into the cavity 115. Adjusting the slider position can allow the user to customize airflow resistance and vapor production. In some embodiments, the slider’s position can be detected by an electrical switch or sensor connected to the electronic control unit 165, enabling the controller 300 to dynamically adjust one or more operating parameters such as temperature, voltage, current, or power delivered to the cartridges 150. For example, as airflow is increased, the control circuitry may boost heating power to counteract cooling effects, ensuring consistent aerosol production. This interactive regulation of airflow and power delivery provides optimal vapor quality and enhances the overall user experience.

[0026] The cartridge receptacles 120 A and 120B of the electronic vaporizer device 100 are configured to securely hold and electrically connect the cartridges 150A and 150B within the internal airtight cavity 115. Each receptacle 120 can be in fluid communication with the other,7134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 collectively forming the cavity that directs airflow during inhalation. The receptacles 120 can be equipped with cartridge heating contacts 245, which supply power from the electronic control unit 165 and power supply 170 to the heating elements 160 inside the cartridges 150, enabling vaporization of the liquid contained in the liquid reservoirs 230. To ensure proper retention during use, the receptacles may employ magnets, friction fits, detents, or snap mechanisms to prevent unintentional dislodgment of the cartridges 150. In a preferred embodiment, a clearance is maintained between the receptacle walls and the cartridge bodies 235, creating airflow channels that guide air from the airflow inlet 102 into the primary air channel inlets 225 of each cartridge. By providing both secure retention and controlled airflow, the cartridge receptacles 120 enable reliable cartridge operation, consistent vapor generation, and seamless integration with the device’s 100 overall vapor delivery pathway.

[0027] The outer cover seal 125 and inner cover seal 130 of the electronic vaporizer device 100 can function cooperatively to create a sealed interface that forms the continuous combined vapor pathway 135. When the cover housing 110 is secured onto the device body 105, the outer cover seal 125 interlocks with the inner cover seal 130, establishing an airtight connection that prevents leakage between the internal airtight cavity 115 and external environment. The inner cover seal 130 is positioned to align with the cartridge vapor outlets 210 of the cartridges 150A and 150B, ensuring that vapor produced by the heating elements 160 is captured and directed into the combined pathway. The outer cover seal 125 can reinforce this alignment and sealing action, guiding the merged aerosol stream through the mouthpiece 140 and vapor outlet 145 for user inhalation. By working together, the seals optimize airflow efficiency, maintain vapor density, and ensure consistent performance of the device 100 while preventing leakage and loss of vapor.

[0028] The aerosol channel 135 of the electronic vaporizer device 100 can function as the continuous airtight pathway that merges and directs vapor generated by the cartridges 150A and 150B toward the mouthpiece 140 and through the vapor outlet 145. Formed by the interlocking of the outer cover seal 125 and inner cover seal 130 when the cover housing 110 is secured to the device body 105, the aerosol channel 135 ensures that vapor flows in a controlled and leak-free manner from the cartridge vapor outlets 210. By combining multiple vapor streams into a single unified pathway, the channel enhances delivery consistency and user experience, whether one or both cartridges 150 are active. The airtight nature of the aerosol channel 135 can prevent vapor loss in the form of condensation in the internal airtight cavity 115 and optimizes efficiency by maintaining vapor density and purity by avoiding dilution with excess air, and ensuring optimal vapor density and temperature withing the desired range. .8134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1This directed flow can also coordinate with the airflow sensors 180A and 180B for reliable activation and consistent vapor delivery during inhalation.

[0029] The mouthpiece 140 of the electronic vaporizer device 100 can serve as the final delivery interface through which the user inhales vapor produced within the device 100. The mouthpiece can be fluidly connected to the aerosol channel 135, which is formed by the interlocking of the outer cover seal 125 and inner cover seal 130 inside the cover housing 110. This configuration can stream the aerosol generated by the cartridges 150A and 150B and emitted from their cartridge vapor outlets 210 are merged into a single, unified flow before reaching the vapor outlet 145 at the mouthpiece. To maintain airtight integrity and prevent vapor leakage, the combined channel may form a compliant seal around the cartridge outlets, using materials such as silicone, elastomers, urethane, or rubber.

[0030] The cartridges 150A and 150B of the electronic vaporizer device 100 can be configured to hold a liquid reservoir 230 and incorporate heating elements 160 that vaporize the liquid into an inhalable aerosol. Each cartridge can be inserted into a corresponding cartridge receptacle 120A, 120B within the internal airtight cavity 115, where they engage with cartridge heating contacts 245 connected to the electronic control unit 165 and power supply 170. During operation, air drawn from the airflow inlet 102 and regulated by the air inlet control 155 enters the primary air channel inlet 225 of each cartridge, mixes with the vapor produced by the heating element, and exits through the cartridge vapor outlet 210. The vapor streams then merge within the aerosol channel 135 and are delivered through the mouthpiece 140 and vapor outlet 145 for user inhalation.

[0031] The device 100 supports multiple activation modes to enhance flexibility. In one embodiment, the cartridges 150 can be activated simultaneously to generate a combined aerosol stream, providing dense vapor output. Alternatively, the user may selectively activate one cartridge at a time, allowing different formulations or flavors to be enjoyed individually. In another embodiment, the cartridges 150 may be activated sequentially, extending device 100 operation by alternating usage between cartridges 150. Activation may be triggered through manual input at the control, which can be the button 175, or automatically by airflow sensors 180A, 180B, which detect inhalation. In certain modes, activation is governed by the earliest of either a button 175 press or inhalation detection, and the device 100 remains active until the latter of button 175 release or cessation of inhalation. This control logic provides reliable activation and reduces vapor waste. This type of activation is possible in all embodiments and should be understood as not being limited to any particular embodiment.9134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1

[0032] In addition to standard cartridges 150, the system may employ cartridges 150 with secondary air inlets 215, as shown in FIG. 6A and FIG. 6B, which communicate pressure changes to an activation sensor while minimizing airflow through the secondary pathway using seals. Other cartridge types with only a single air channel are also compatible with the vaporizer. For users preferring vapor from only one cartridge, a blocking cartridge or dummy cartridge may be inserted into one receptacle to close off airflow through part of the aerosol channel 135, forcing airflow exclusively through the active cartridge. The dummy cartridge may be a simple, low-cost component molded from plastic, silicone, or similar materials, shaped to fit within the receptacle and form an airtight seal. This feature enhances device 100 versatility, allowing the vaporizer to operate effectively with one or more cartridges 150 depending on user preference.

[0033] In the event the user desires vapor from only a single cartridge, a blocking cartridge, also known as a dummy cartridge, may be inserted into one of the receptacles of the device 100 in order to close off air flow through a portion of the combined aerosol channel of the lid. This has the effect of forcing all air flow from the air inlet channel of the vaporizer through the single functional cartridge inserted into the other receptacle and aerosol from only a single cartridge entering the combined aerosol channel of the lid. If one receptacle were left unblocked, excess air would be drawn directly into the combined aerosol channel, which would dilute and cool the vapor from the active cartridge. This excess airflow would also reduce draw resistance to a level that makes it difficult for a user to sustain a prolonged inhalation, which is typically preferred for effective vapor delivery. In order to minimize cost, the blocking cartridge can have a simple construction with few or even just a single part. For example, it may be molded as a single piece from plastic, silicone, TPE, TPU, or other materials known in the art. The blocking cartridge may have a form that approximates the shape of a standard cartridge so that it fits into the receptacle of the vaporizer and forms an airtight seal against components of the lid.

[0034] The air inlet control 155 of the electronic vaporizer device 100 regulates the amount of air that enters the internal airtight cavity 115 through the airflow inlet 102, thereby controlling the airflow that reaches the cartridges 150A and 150B. In one embodiment, the air inlet control 155 includes an airflow adjustment slider working with an inlet seal, where the degree of overlap between corresponding openings determines the airflow rate into the cavity. By adjusting the slider, the user can fine-tune inhalation resistance and vapor density. The air inlet control 155 interacts with the electronic control unit 165 and controller 300, which may detect the slider’s position through an electrical switch or sensor and adjust one or more10134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 operational parameters — such as voltage, current, power, or temperature — delivered to the heating elements 160. This integration ensures that increased airflow does not cool the vapor excessively, maintaining consistent aerosol quality delivered through the aerosol channel 135, mouthpiece 140, and vapor outlet 145.

[0035] The heating element 160 of the electronic vaporizer device 100 can be responsible for converting electrical energy into heat to vaporize the liquid contained within the liquid reservoir 230. When a cartridge is inserted into the cartridge receptacle 120A or 120B, the heating element 160 electrically couples with the cartridge heating contacts 245, which draw power from the power supply 170 through the electronic control unit 165 and controller 300. Activation may occur by user input through the button 175 or automatically via the airflow sensors 180A, 180B, which detect inhalation. As the heating element 160 raises the liquid to vaporization temperature, the resulting aerosol is directed through the cartridge vapor outlet 210, into the aerosol channel 135, and out through the mouthpiece 140 and vapor outlet 145. By interacting with airflow regulation from the air inlet control 155, the heating element 160 ensures efficient vaporization while maintaining consistent vapor density and quality during use.

[0036] The electronic control unit 165 of the electronic vaporizer device 100 can manage and coordinates the operation of the device 100 by regulating electrical power supplied from the power supply 170 to the heating elements 160 of the cartridges 150A and 150B through the cartridge heating contacts 245. The electronic control unit 165 can interact with the controller 300, which executes control logic based on user input received via the button 175 and real-time data from the airflow sensors 180A, 180B. When inhalation is detected, the electronic control unit 165 can activate the heating elements 160 to generate vapor. The electronic control unit 165 may also adjust operational parameters such as voltage, current, power, or temperature according to airflow conditions managed by the air inlet control 155, thereby maintaining consistent vapor quality. Additionally, it interfaces with optional user-facing elements such as the display 185 and charge control circuitry 195, enabling status monitoring, power adjustment, and safe battery charging through the charge connector 190.

[0037] The power source 170 of the electronic vaporizer device 100 can provide the electrical energy required to operate the system and can be embodied as a rechargeable battery. The battery may be charged through a charge connector 190, such as a USB port, and its charging process is managed by charge control circuitry 195 to ensure safe and efficient recharging. To protect the power source 170 from damage due to potential liquid leakage from the cartridges 150A and 150B, the battery compartment is physically isolated from the internal11134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 airtight cavity 115 by an internal wall that can be created by device body 105. This arrangement allows the device 100 to maintain electrical safety and long-term durability while ensuring that vaporization components remain completely separated from the power supply.

[0038] The power source 170 can directly interact with the electronic control unit 165 and controller 300, which distribute power to the heating elements 160 in the cartridges 150 through the cartridge heating contacts 245. The control circuitry can adjust power delivery in response to data from the airflow sensors 180A, 180B, which detect inhalation activity. In some embodiments, the sensors 180 provide analog and / or multi-level feedback rather than simple ON / OFF signals, enabling the controller 300 to adjust the voltage, current, or temperature delivered to the heating elements 160. In further embodiments, the airflow sensors 180 may be digital sensors capable of outputting multi-level signals with more than one bit of resolution, such as digital pressure sensors, digital mass airflow sensors, or MEMS-based flow sensors. Similarly to analog sensors, these higher resolution digital outputs allow finer granularity in detecting inhalation strength, thereby permitting more precise control of heating power and improved consistency in aerosol production. For example, when greater airflow is detected via the air inlet control 155, the controller 300 may increase power output using methods such as PWM control to counteract cooling effects and maintain stable aerosol production.

[0039] The power source 170 can also support a flexible control of operational modes. In one embodiment, the user can set voltage, current, or temperature levels manually via the button 175 or a combination of interface elements, while in another embodiment, the control unit applies settings automatically based on inhalation conditions. The circuitry may further enable independent power regulation for each cartridge, which is beneficial when the liquids contained in cartridges 150A and 150B differ in composition or electrical resistance. By enabling fine adjustments and adaptive power delivery, the power source 170 and its associated control circuitry can deliver consistent vapor quality, extend device 100 functionality, and optimize efficiency across a wide range of use conditions.

[0040] The control of the electronic vaporizer device 100 can function as a primary user interface element that allows control over device 100 operation. Button 175 control of the electronic vaporizer device 100 is described herein for purposes of explanation, but it will be understood that other means of control, such as an application on a connected device, wireless input, capacitive touch sensitive areas, pressure sensors, pressure switches, pressure sensors, airflow sensors, and / or other triggering mechanisms, may also be used to activate the device. The button 175 can function as a primary user interface element that allows manual control over device 100 operation. For example, when pressed, the button 175 sends a signal to the12134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 electronic control unit 165 and controller 300, which in turn activate the power source 170 to deliver energy to the heating elements 160 of the cartridges 150A and 150B through the cartridge heating contacts 245. This enables the user to manually initiate vaporization regardless of airflow conditions. The button 175 may also serve additional functions, such as adjusting voltage, current, power, or temperature levels for vapor production, or toggling between simultaneous, selective, or sequential cartridge activation modes. In some embodiments, the button 175 works in conjunction with the airflow sensors 180A and 180B, allowing activation to be initiated by either a button 175 press or inhalation, whichever occurs first, with deactivation occurring when both inputs are released. The display 185 may provide visual feedback on settings adjusted through the button 175, further enhancing user control and customization.

[0041] The airflow sensors 180 A and 180B of the electronic vaporizer device 100 can be configured to detect inhalation by monitoring changes in airflow or pressure within the internal airtight cavity 115 and the cartridges 150A, 150B. When a user inhales through the mouthpiece 140 and vapor outlet 145, the sensors generate signals that are communicated to the electronic control unit 165 and processed by the controller 300. Based on these signals, the control circuitry activates the power source 170 to supply energy to the heating elements 160 via the cartridge heating contacts 245, thereby initiating vaporization of the liquid contained in the liquid reservoirs 230. In some embodiments, the sensors 180 provide analog or variable-level output rather than simple ON / OFF detection, allowing the control circuitry to dynamically adjust voltage, current, or temperature supplied to the heating elements 160. In further embodiments, the airflow sensors 180 may be implemented as digital sensors capable of outputting multi-level signals with more than one bit of resolution, such as digital pressure sensors, digital mass airflow sensors, or MEMS-based flow sensors. These sensors 180 can enable finer detection of inhalation intensity, allowing the control circuitry to more precisely regulate heating power and maintain consistent vapor quality. This interaction between the airflow sensors 180, seals, and electronic control unit 165 enables precise, real-time regulation of vapor production, ensuring consistent density and preventing vapor loss during inhalation.

[0042] The user interface 185 of the electronic vaporizer device 100 provides the user with direct control and feedback over the operation of the system. In some embodiments, the user interface 185 includes a visual display that shows operational parameters such as battery level of the power source 170, output power or temperature delivered by the electronic control unit 165, and the status of the cartridges 150A and 150B. It may also display usage statistics, such as puff counts or session duration, managed by the controller 300. The user interface 185 works13134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 in conjunction with the button 175, allowing the user to adjust voltage, current, power, or temperature settings, toggle between simultaneous or selective cartridge activation, or initiate preheat functions. Signals from the interface are processed by the control circuitry to regulate the heating elements 160, synchronize with airflow sensors 180 A and 180B, and coordinate lighting features integrated into the cover housing 110 or viewing window 205. By providing both control and feedback, the user interface 185 ensures precise customization of vaporization and enhances the overall usability of the device 100. The device 100 may also be equipped with a visual display that shows these settings, as well as operational statistics such as the number of inhalations taken within a specified time frame. Wireless communication capability, such as Bluetooth or WiFi, may be integrated into the vaporizer, allowing users to configure settings remotely via a connected device 100 and visualize usage data via an app or webpage interface.

[0043] To enhance the user experience, the vaporizer may include one or more viewing windows 205 that allow users to observe the liquid level within the cartridges 150. Additionally, the device 100 may comprise one or more internal light sources that illuminate the cartridges 150, making it easier to monitor the liquid levels. These lights can be activated by pressing a button 175 or during an inhalation and may remain on for a set period of time (e.g., 2-10 seconds) after activation.

[0044] While the electronic vaporizer device 100 is described in connection with the arrangements shown in the figures, the construction of the device 100 is not limited to these examples and may vary in alternative embodiments. For instance, the mouthpiece 140 may be positioned on a different surface of the device 100, the cover housing 110 may be designed to detach from the side rather than the top, or the power source 170 may be located adjacent to the internal airtight cavity 115 rather than beneath it. Certain features, such as the viewing window 205 or the user interface 185, may be omitted in some configurations, depending on design requirements. Furthermore, the overall form of the vaporizer may take any suitable shape and may be constructed from a variety of materials, including plastics, metals, rubbers, silicones, or combinations thereof, without departing from the scope of the invention.

[0045] FIG. 2 illustrates an electronic vaporizer device 100 with an airflow blocking seal 200 in a closed position, according to an embodiment. As shown in FIG. 2, the electronic vaporizer device 100 with an airflow blocking seal 200, according to an embodiment. In this configuration, the airflow blocking seal prevents or significantly restricts airflow from entering the secondary air inlet 215 of the cartridges 150A and 150B, thereby ensuring that the majority or entirely of inhaled air is directed through the primary air channel inlet 225. This closed14134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 arrangement maintains the integrity of the internal airtight cavity 115 and improves vaporization efficiency by minimizing unintended airflow paths that could dilute the aerosol stream.

[0046] FIG. 3 illustrates an electronic vaporizer device 100, according to an embodiment. As shown in FIG. 3, the electronic vaporizer device 100 without an airflow blocking seal 200, according to an embodiment. In this state, the lack of an airflow blocking seal allows airflow to pass through the secondary air inlet 215, allowing additional air to pass through the secondary air inlet 215 or allowing the electronic vaporizer device 100 to work with cartridges that contain only a single air pathway that enters the cartridge through the bottom of the cartridge. This configuration supports activation of the electronic control unit 165 and ensures responsive engagement of the heating elements 160 within the cartridges 150A and 150B, allowing vapor to be consistently generated and delivered through the aerosol channel 135, mouthpiece 140, and vapor outlet 145.

[0047] FIGS. 4A-4C illustrate perspective views of the electronic vaporizer device 100 showing the cover housing 110 and receptacle arrangement from different angles, according to an embodiment. These views show the configuration of the cover housing 110 in relation to the device body 105, as well as the arrangement of the cartridge receptacles 120A and 120B that form part of the internal airtight cavity 115. The figures demonstrate how the cover housing 110 is positioned to secure the cartridges 150, align with the outer cover seal 125 and inner cover seal 130, and contribute to the formation of the aerosol channel 135 leading to the mouthpiece 140 and vapor outlet 145. By presenting the device 100 from multiple perspectives, the figures emphasize the structural integration between the cover, receptacles, and sealing components, ensuring proper cartridge retention and consistent vapor delivery.

[0048] FIGS. 5A-5C illustrate perspective views of the electronic vaporizer device 100 showing the engagement of the outer cover seal 125 and inner cover seal 130, according to an embodiment. These views depict how the seals interlock when the cover housing 110 is secured to the device body 105, forming a continuous airtight connection that defines the aerosol channel 135. The figures highlight the manner in which the seals align around the cartridge vapor outlets 210 of the cartridges 150A and 150B, ensuring that aerosol produced by the heating elements 160 is captured and directed toward the mouthpiece 140 and vapor outlet 145. By illustrating the sealing interface from multiple perspectives, the figures demonstrate how the combined action of the outer and inner cover seals 130 prevents leakage, maintains cavity integrity, and ensures consistent vapor flow during device 100 operation.15134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1

[0049] FIGS. 6A-6B illustrate an example cartridge for use with the electronic vaporizer device 100, according to an embodiment. The cartridge can include a cartridge body 235 that encloses a liquid reservoir 230 for storing the vaporizing substance. At its lower end, the cartridge base 240 provides structural support and carries the cartridge heating contacts 245, which electrically couple the cartridge to the electronic control unit 165 and power source 170 when inserted into the cartridge receptacles 120 A or 120B. A heating element 160 positioned within the reservoir converts liquid into vapor during operation. Incoming air is directed through the primary air channel inlet 225, where it mixes with the vaporized substance before traveling toward the cartridge vapor outlet 210. The cartridge also incorporates a cartridge mouthpiece 220, through which the aerosol may be inhaled when used in a stand-alone configuration or connected with the aerosol channel 135 of the vaporizer.

[0050] Further, FIG. 6B illustrates another perspective view of the same cartridge, emphasizing the airflow structure. In addition to the primary air channel inlet 225, the cartridge includes a secondary air inlets 215 that connects to a secondary air channel, which in certain embodiments of the vaporizer device 100 allows extra air to enter the cartridge and / or communicates pressure changes to the airflow sensors 180A, 180B of the vaporizer. In some embodiments, airflow through this secondary channel is restricted by airflow block seals 200A, 200B, ensuring that most or all inhaled air is drawn through the primary inlet for efficient vaporization. The figure also shows the integration of the cartridge body 235, liquid reservoir 230, cartridge base 240, and cartridge heating contacts 245, all of which work together to securely position the cartridge within the vaporizer and enable both airflow routing and electrical activation. Collectively, FIGS. 6A and 6B demonstrate how the cartridge components interact to provide consistent vapor generation and seamless integration with the vaporizer system.

[0051] In an alternative embodiment, the cartridge 150A, 150B may include only a single air channel without any secondary air inlet or secondary air channel. In this configuration, all inhaled air enters exclusively through the primary air channel inlet 225, mixes with vapor generated by the heating element 160 in the liquid reservoir 230, and exits through the cartridge vapor outlet 210. Depending on the location of the primary air channel inlet 225, this embodiment eliminates the need for airflow block seals 200A, 200B, since no secondary pathway exists to divert airflow. The simplified design may reduce manufacturing cost and complexity while still ensuring reliable aerosol production. The cartridge body 235, cartridge base 240, and cartridge heating contacts 245 remain configured to securely fit into the cartridge receptacles 120 A, 120B of the vaporizer and provide electrical and airflow connectivity,16134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 thereby maintaining seamless integration with the electronic control unit 165 and the aerosol channel 135.

[0052] FIG. 7 illustrates an exploded view of the electronic vaporizer device 100, according to an embodiment. Most or all figures show the arrangement of major components, including the device body 105, the cover housing 110, the internal airtight cavity 115 (not shown in FIG. 7) with cartridge receptacles 120 A and 120B, and the corresponding cartridges 150A and / or 150B and a blocking cartridge 250.

[0061] Traditionally, personal vaporizers have been limited to using a single cartridge at a time, restricting the user’s ability to customize flavor, vapor density, or therapeutic blends. In addition, many devices lack proper airflow control and sealing, leading to leakage, inconsistent vapor generation, and poor activation of sensors. Such limitations reduce both user satisfaction and device efficiency. For example, when airflow bypasses the cartridge, vapor production is diminished, and the user may perceive weak or diluted inhalation.

[0062] Accordingly, an electronic vaporizer device 100 is disclosed, comprising a cover housing 110 forming an internal airtight cavity 115 with multiple cartridge receptacles 120A, 120B, an outer cover seal 125 and inner cover seal 130 interlocking to form a combined vapor19134357-0001UT01 / 9896605.2Attorney Docket No.: 134357-0001 WOO 1 pathway 135, and a mouthpiece 140 including a vapor outlet 145. The device houses two or more cartridges 150 A, 150B with respective heating elements 160 and airflow pathways, supplied power by an electronic control unit 165 with a power supply 170, button 175, and airflow sensors 180A, 180B when inhalation is detected.

[0063] An electronic vaporizer device 100 of this type offers a variety of industrial and consumer benefits, including simultaneous or selective cartridge operation, customizable vapor blending, and optimized airflow control. For example, in nicotine or tobacco extract applications, the sealed cavity and airflow control reduce leakage, improve vapor density, and provide more consistent inhalation. Further, the device 100 may incorporate a viewing window 205 and lighting features to enhance usability, as well as charging circuitry 195 for reusability, supporting sustainable and reliable operation across diverse industries including medical, cannabis, flavoring, recreational, and / or wellness sectors.
