Humidifier

Description

RELATED APPLICATIONS

This application claims the benefit under 35 U.S.C. § 119 (e) of U.S. Provisional Patent Application Ser. No. 63/637,271, filed on Apr. 22, 2024, titled “HUMIDIFIER,” the entire contents of which are incorporated by reference herein.

FIELD OF THE INVENTION

The invention relates to a humidifier, and particularly, a humidifier incorporating an integrated mist illumination chamber that produces visually aesthetic flame-like or lantern-like lighting effects in addition to functional humidity dispersion.

BACKGROUND OF THE INVENTION

Conventional humidifiers are primarily designed to increase humidity levels in indoor environments to improve comfort, prevent dryness, and support health and wellness. These devices typically function by dispersing water vapor or mist into the surrounding air. However, traditional humidifiers are generally utilitarian in appearance and operation, offering little or no aesthetic value beyond their basic humidification function.

Various improvements have been proposed in the art to enhance the user experience with humidifiers, such as introducing aromatherapy features, sound generators, or color-changing lights. Nevertheless, these enhancements have often been limited to superficial add-ons, lacking meaningful integration between humidification, lighting, and aesthetic output. In many existing products, light sources are merely appended to the humidifier body without interacting meaningfully with the generated mist or the humidification process itself. As a result, these devices fail to achieve a cohesive or transformative ambient effect.

Furthermore, in conventional systems, mist emission is often turbulent, uncontrolled, and opaque to illumination, making it difficult to create visually striking mist displays. Existing devices that attempt to backlight or illuminate mist often suffer from poor light-mist interaction, with mist scattering light inefficiently and producing hazy or muddy visuals rather than defined, flame-like or lantern-like effects. Additionally, many humidifiers operate without sufficient safety mechanisms, such that accidental operation without water, improper tank seating, or exposure of sensitive electronics to moisture can lead to device failure or hazards.

There is a clear and unmet need for humidification devices that seamlessly integrate functional mist generation with dynamically illuminated mist presentation to produce ambient visual experiences that rival or enhance conventional lighting fixtures or decorative objects. There is a further need for such devices to incorporate intelligent sensing, fluid control, and modular design elements to ensure safe operation, ease of maintenance, aesthetic adaptability, and compatibility with modern smart home environments.

Accordingly, the present invention addresses these shortcomings by providing a portable, free-standing humidifier that incorporates a lighting and misting chamber, wherein fine mist generated by a transducer is illuminated within a specially designed transparent or translucent chamber to produce a flame-like or lantern-like visual effect. The invention further incorporates a mist tube to concentrate and guide mist flow, multiple strategically positioned light sources for optimized illumination dynamics, dual blower systems for enhanced mist propulsion, magnetic sensing mechanisms for safe operation, and intelligent controllers for user customization and smart system integration.

By combining functional humidification with compelling ambient lighting, the invention transcends traditional humidifier designs and creates an entirely new product category at the intersection of wellness technology, ambient lighting, and smart home integration.

SUMMARY OF THE INVENTION

The present invention relates to humidifiers that not only generate and disperse mist for functional humidification but also provide an enhanced visual aesthetic by illuminating the mist within a specialized chamber. The humidifier generally includes a tank configured to hold a fluid, a base configured to support the tank, a mist generator positioned within the base and configured to generate mist from the fluid, and a chamber positioned within the tank. The chamber includes a mist inlet in fluid communication with the mist generator and a mist outlet through which mist is expelled into the ambient environment.

At least one light source is positioned relative to the chamber and is configured to emit light into the chamber such that mist traveling through the chamber is illuminated, creating a visually appealing flame-like or lantern-like effect. At least one blower positioned within the base is configured to propel the mist generated by the mist generator upwardly through the chamber toward the mist outlet.

In some examples, the mist generator may comprise a transducer, and multiple light sources may be positioned around the transducer to enhance the uniformity and intensity of the lighting effect. In certain embodiments, the fluid contained within the tank surrounds at least a portion of the external surface of the chamber, further enhancing the visual depth and glow of the illuminated mist column.

To promote operational safety, the humidifier may also include a magnetic sensing mechanism configured to detect whether the tank is properly seated on the base, and to prevent operation of the mist generator and blower when the tank is improperly installed. In some implementations, two blowers may operate in tandem to increase mist velocity and enhance the visual turbulence of the illuminated mist.

The chamber may be at least semi-transparent or translucent, allowing for controlled diffusion and refraction of light. In further examples, the chamber may extend between the light source and the mist outlet of the tank, forming a dedicated illuminated mist pathway. The humidifier may also include a mist tube positioned within the chamber to concentrate mist flow, and the light source may be configured to emit light within the interior of the mist tube, the chamber, or both.

In another example, the chamber may extend from a bottom side of the tank and project upward toward the mist outlet at the top side of the tank. The bottom of the tank may include a valve assembly to regulate fluid delivery to the mist generator, and may also include a blower cover to protect internal components. The chamber itself may be formed as a cylindrical tube or other shape suitable for optimizing mist flow and light distribution.

Other devices, apparatus, systems, methods, features and advantages of the invention are or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, within the scope of the invention, and be protected by the accompanying claims.

For purposes of reference and description, the humidifier 100, 800 of the present invention is considered to have horizontal (x-axis) and vertical device axis (y-axis) and a z-axis, as shown in FIGS. 1 and 8 along which the components of the humidifier are positioned relative to each other. Terms such as “axial” and “axially” are assumed to refer to the respective axis or any direction or axis parallel to the device axis, unless indicated otherwise or the context dictates otherwise. For convenience, movement relative to a device axis may alternatively encompass movement relative to an axis that is parallel to the device axis that is specifically illustrated in FIGS. 1 and 8, unless the context dictates otherwise. Thus, linear translation “along the device axis z” is not limited to translation directly on (coincident with) the device axis, but also encompasses translation parallel to the device axis z, depending on the context. Similarly, rotation “about the device axis y” also encompasses rotation about an axis that is parallel to the device axis y, depending on the context.

Further, the humidifier 100, 800 of the present invention is considered to have a height (h), length (l) and width (w), as also shown in FIGS. 1 and 8. These dimensional descriptors assist in defining proportionality and arrangement of internal and external components to optimize both functionality and aesthetic presentation.

As illustrated and discussed in the following figures, examples of a humidifier 100, 800 is provided. In the example, the humidifier 100, 800 is a portable, free-standing humidifier. “Portable” being defined as having the ability to be carried or moved with ease. “Free standing” being defined as having the ability to remain stable and upright without external restraints. It should further be understood that the term “humidifier” may interchangeably used with the terms “mist generator” or any term that refers to an apparatus that in general, draws a liquid from a tank or source and disperses it into the air in the form of mist, vapor, and/or steam. The inventive humidifier not only performs the functional task of humidification but also serves as a visually impactful decorative object, capable of enhancing the atmosphere of indoor spaces.

As will be illustrated and discussed below, in the examples of the humidifier 100, 800 of the present invention, the humidifier 100, 800 is a portable ultrasonic humidifier that incorporates a lighting assembly 702, 1002 that comprises a chamber 302, 1320 that is illuminated by at least one light source 502, 1202 to create a flickering flame or lantern effect. This integration of mist generation and illumination within a translucent or at least semi-transparent chamber establishes not only a functional benefit of humidification but also a sensory-enhancing visual spectacle, offering users a multi-sensory experience that transcends typical humidifier designs. The simulated flame effect adds a dynamic, soothing aesthetic that can complement the ambiance of residential, commercial, or hospitality environments, thereby expanding the utility and appeal of the device beyond its primary humidification function.

FIG. 1 is a top perspective view of one example of an implementation of a humidifier 100 of the present invention. In general, humidifier 100 comprises of tank assembly 102 supported by or removably seated above base assembly 104. The tank assembly 102 comprises of a tank 318 for holding a liquid (e.g., water) to be humidified and mist outlet 108 positioned on top side of tank 106. Optionally, humidifier 100 may also include shell 112 for covering tank 318. Shell 112 may be structured as a sleeve and may include at least one or more decorative elements 114 for not only enhancing the aesthetic appeal of humidifier 100 but also to enhance the flickering flame or lantern effect of lighting assembly 702. Decorative elements 114 may take the form of cutouts, engravings, or patterns that selectively diffuse or refract the light passing through the shell 112, intensifying the perception of movement and depth in the illuminated mist, thereby creating an even more captivating visual phenomenon. In other examples, decorative elements 114 may also or alternatively be included on tank 318 and/or chamber 302.

Further, optionally, humidifier 100 may also include at least one handle 110 attached to tank assembly 102, namely tank 318 for allowing a user to hold or carry humidifier. Handle 110 may attach to tank assembly by attachment elements 112, 208. While the attachment elements 112, 208 are shown to be thumb screws, it should be understood that any attachment mechanism known in the art may be utilized, including but not limited to hook and loop fasteners (e.g., Velcro), friction fit, magnetic attachments, press studs, clips, or snap-fit connectors.

FIG. 2 is a bottom perspective view of humidifier 100. FIG. 2 illustrates base assembly 104 comprising a bottom side, plate or cover 202, one or more vent openings 204 for venting heat from blower 718 and/or transducer 602 and one or more feet 206 for supporting base assembly 104 over a surface. As stated above, humidifier 100 is configured as a portable, free-standing humidifier. The base assembly 104 includes a bottom plate or cover 202 that encloses and protects the underside of the base assembly. One or more vent openings 204 are formed through the bottom plate 202, allowing for the venting of heat generated by internal components, such as the blower 718 and transducer 602, during operation. Proper heat dissipation through vent openings 204 prevents thermal stress, enhances operational safety, and prolongs the lifespan of sensitive electronic and mechanical components housed within base assembly 104. The vent openings 204 ensure that excessive heat does not build up within the base assembly 104, thereby improving device safety and extending component lifespan. Further, base assembly 104 is supported by one or more feet 206 that project from bottom plate 202. The feet 206 are configured to maintain the base assembly 104 spaced slightly above the supporting surface (e.g., tabletop, shelf, or floor), allowing for improved airflow and ventilation while also providing physical stability to humidifier 100. The slight elevation created by feet 206 also serves to acoustically isolate the humidifier from the surface it rests upon, reducing operational noise transmission and contributing to a quieter user experience. The portable and free-standing design of humidifier 100 permits it to be easily placed and operated on a variety of surfaces without requiring permanent installation, enhancing user convenience and device versatility.

FIG. 3 is a see-through top perspective view of humidifier 100. Shell 112 and/or tank 318 may be made of any transparent, translucent, semi-transparent or semi-translucent material known in the art for allowing lighting assembly 702 within tank 318, namely chamber 302 to be seen externally by a user. The selection of material for shell 112 and tank 318 optimizes the interaction between emitted light and mist flow, with translucency levels tailored to achieve a balance between light diffusion and visibility of mist movement, thereby enhancing the overall visual effect while maintaining the structural integrity required for containing fluids.

As shown in FIG. 3, lighting assembly 702 comprises of chamber 302 that may be in the form of a tube or other elongated member extending from bottom plate 314 of tank 318. Chamber 302 may include at least two open ends, where one end acts as a mist inlet and is in fluid communication with transducer 602 for receiving mist created by transducer 602 and the other open end is a mist outlet 312 for expelling mist created by transducer 602 from humidifier through chamber 302 and out from mist outlet 108. The elongated configuration of chamber 302 facilitates a laminar upward flow of mist, ensuring a continuous and uninterrupted mist column that can be illuminated evenly by light source 502, thereby maximizing the lantern or flame-like visual effect. Additionally, the vertical orientation of chamber 302 aligns with the natural buoyancy of warm mist and airflow, promoting efficient mist propulsion through outlet 312.

Similar to shell 112 and/or tank 318, chamber 302 may also be made of any transparent, translucent, semi-transparent or semi-translucent material known in the art for allowing both the light emitted within chamber 302 and the mist that flows through chamber 302 to be seen externally by a user. The combination of the light and mist that flows through chamber 302 creates a flame or lantern-like effect. This effect is further enhanced by the interaction of scattered light with the micron-sized mist particles, creating dynamic patterns of brightness, movement, and opacity that simulate the organic and unpredictable nature of real flames, thus offering a highly immersive and captivating visual presentation.

A valve assembly 304 for controlling the flow of fluid from the tank assembly 102 to the base assembly 104 is also provided. The valve assembly 304 is integrated into the bottom plate 314 of tank 318 and regulates the delivery of fluid held within the tank 318 to the base assembly 104, specifically to the transducer 602 positioned within the base assembly 104. The valve assembly 304 generally comprises a fill cap seal 706, a spring 708, a pin or plunger 710, a cap gasket 712, and a fill cap 714.

The fill cap 714 is secured to the bottom plate 314 of the tank 318 and houses the internal components of the valve assembly 304. In one example, the fill cap 714 is removably attached to the bottom plate 314 via a threaded engagement, allowing the fill cap 714 to be screwed on and off the bottom plate 314 by a user. This configuration enables the user to remove the fill cap 714 to access the interior of the tank 318 for refilling the tank 318 with water through opening 702, and thereafter securely reattach the fill cap 714 to seal the tank 318 for normal operation. The fill cap seal 706 is disposed adjacent to the fill cap 714 to provide an initial barrier against fluid leakage and to ensure that the valve assembly remains sealed when not engaged.

The spring 708 is positioned within the fill cap 714 and is operatively engaged with the pin or plunger 710. The spring 708 applies a continuous biasing force to the pin/plunger 710 in a direction toward the closed position. The pin/plunger 710 is axially movable within the fill cap 714 between a sealed closed position, wherein the pin/plunger 710 seats against the cap gasket 712 to block the outlet opening 702 of tank 318, and an open position, wherein the pin/plunger 710 is displaced from the cap gasket 712 to allow fluid flow through the valve assembly 304.

In operation, when the tank 318 of tank assembly 102 is properly seated onto the base body 316 of the base assembly 104, an actuator or actuator pin 716, positioned within the base body 316, engages the pin/plunger 710. Upon engagement, the actuator pin 716 exerts an upward force on the pin/plunger 710, thereby compressing the spring 708 and displacing the pin/plunger 710 away from the cap gasket 712. This displacement creates a fluid pathway from the interior of the tank 318 through the valve assembly 304 and into the base assembly 104, allowing fluid to flow under gravitational force to the transducer 602 for atomization.

The fill cap seal 706 and cap gasket 712 function cooperatively to ensure that when the actuator pin 716 is not engaged with the pin/plunger 710, the valve assembly 304 maintains a watertight seal, preventing fluid leakage from the tank 318. When the tank 318 is lifted or otherwise removed from the base body 316, the actuator pin 716 disengages from the pin/plunger 710, permitting the spring 708 to decompress and force the pin/plunger 710 back into sealing engagement with the cap gasket 712. In this closed state, the valve assembly 304 effectively isolates the fluid within the tank 318, preventing any leakage or unintended fluid release.

The valve assembly 304 thereby provides a simple yet highly effective mechanism for enabling and disabling fluid flow in response to the tank's engagement with the humidifier base. The use of a spring-biased pin/plunger 710 in conjunction with dual sealing elements (fill cap seal 706 and cap gasket 712) ensures reliable operation over repeated cycles of tank installation and removal, while minimizing the risk of leaks that could damage internal humidifier components or surrounding surfaces. The design further ensures that fluid flow is only enabled during proper tank seating, enhancing the overall safety and user convenience of the humidifier 100.

In addition to the valve assembly, the bottom plate 314 of tank 318 further includes a magnet cover 306. The magnet cover 306 houses a magnet or ferromagnetic component (not shown) that is part of a magnetic detection system for verifying proper tank placement. The magnet or ferromagnetic component housed within the magnet cover 306 is configured to magnetically correspond, attach, or otherwise communicate with a separate magnet or ferromagnetic component 606 positioned within the base assembly 104. The magnet 606 may be operatively associated with a sensor 722 that is in communication with a controller 720.

The magnetic sensor mechanism is configured to detect the presence or absence of the tank 318 on the base body 316. When the tank 318 is correctly seated on the base body 316, the magnetic field generated by the magnet housed within the magnet cover 306 interacts with the magnet 606, allowing the sensor 722 to detect the magnetic coupling. Upon detecting the proper presence of the tank 318, the sensor 722 sends a signal to the controller 720, which permits operation of the humidifier 100, including activation of the transducer 602 or other internal systems. Conversely, if the tank 318 is not properly seated on the base body 316, meaning the magnetic field is not detected by the sensor 722, the controller 720 prevents operation of the humidifier 100. This magnetic sensing mechanism serves as a safety feature, ensuring that the humidifier 100 cannot operate when the tank 318 is absent, improperly aligned, or improperly secured, thereby reducing the risk of malfunction, dry-running of internal components, or leakage-related hazards.

Bottom plate 314 further includes a transducer cover 308 and a blower cover 310. The transducer cover 308 is positioned to protect the transducer 602 housed within the base assembly 104, while the blower cover 310 is positioned to shield blower-related components within the base assembly 104. Both covers 308, 310 offer additional protection for the internal components of the base assembly 104 from exposure to the fluid held within the tank 318. These covers provide physical barriers that prevent incidental contact between water and sensitive electronic or mechanical components, thereby improving the durability, operational reliability, and safety of the humidifier 100. These protective covers act as physical barriers designed to compartmentalize and isolate critical electrical and mechanical parts from accidental liquid exposure, condensation, or humidity-related deterioration. The separation improves maintenance ease, reduces the risk of short circuits, minimizes mechanical contamination, and extends the overall operational lifespan of humidifier 100. Further, by optimizing the airflow routing within the enclosed base, these covers contribute to improved cooling of internal components such as transducer 602 and blower 718, enhancing thermal management efficiency during extended operation periods.

FIG. 4 is top perspective view of the humidifier 100 with the shell 112 and tank 318 removed and FIG. 5 is a top view of the humidifier 100 of FIG. 4. In addition to the features described above, the humidifier 100 includes a chamber 302 that extends from the bottom plate 314 of the tank 318. Chamber 302 may be formed as a tube or other elongated member that projects upward from the base assembly 104. The chamber 302 is configured such that fluid contained within the tank 318 may surround at least a portion of the external surface of chamber 302. Chamber 302 includes at least two open ends, wherein a first open end acts as a mist inlet that is in fluid communication with the transducer 602 to receive mist generated by the transducer 602, and a second open end forms a mist outlet 312 for expelling the mist through chamber 302 and out of the humidifier 100 via a mist outlet 108. Submerging or closely encasing lower portion of chamber 302 within the tank's water volume also enhances visual magnification effects, causing the illuminated mist to appear larger, deeper, and more dynamic to external observers.

Shown in FIGS. 5 and 6, at least one light source 502 is positioned within the base assembly 104 or base body 316. The light source 502 is configured to emit light into the interior of chamber 302 to illuminate chamber 302 from within. In the present example, chamber 302 extends between light source 502 and mist outlet opening 108, with the light source 502 positioned generally along the same y-axis as outlet opening 108 and/or mist outlet 312. However, it should be understood that in other examples, such as that shown in FIG. 12 for humidifier 800, light source 502 may be positioned in any location within the base body 316 that permits light to enter and illuminate the interior of the chamber 302. Light source 502 may be configured to illuminate only a portion of the interior of chamber 302 or can be configured to illuminate the entire interior length of chamber 302. Positioning light source 502 along the principal vertical axis optimizes the directionality and uniform distribution of emitted light through rising mist columns, maximizing the simulated flame effect. Depending on user settings, light source 502 may also be configured for intensity modulation, color variation, or programmed flickering patterns to simulate different visual atmospheres, such as candlelight, bonfire glow, or soft lantern radiance.

In alternative examples, the light source 502 may be positioned within chamber 302 itself or near mist outlet 108 or outlet 312, where it is configured to emit light downward into the chamber 302 to illuminate the interior. The light source 502 may include any suitable type of light known in the art, including one or more LEDs, incandescent bulbs, tungsten lamps, fluorescent lights, or discharge lamps.

As mist is generated by the transducer 602 and flows upward through chamber 302 toward mist outlet 108, the emitted light from light source 502 illuminates the mist particles traveling through the transparent, translucent, semi-transparent, or semi-translucent material forming the chamber 302. This combination of light and mist within chamber 302 creates a flame-like, lantern-like, or glowing effect that is externally visible to a user, providing a visually appealing aesthetic feature that enhances the overall appearance and user experience of humidifier 100. The dynamic interaction between rising mist and patterned light diffusion creates an ever-changing visual landscape, mimicking the organic randomness of natural flames. This multi-sensory presentation—combining sight, ambient humidity, and often subtle sound—produces a relaxing, almost meditative user environment. As such, the humidifier of the present invention transcends pure functional humidification, evolving into an integrated ambient wellness device suitable for homes, spas, offices, and hospitality venues.

FIG. 6 is a top perspective view of humidifier 100 with the chamber 302 and bottom plate 314 (together referred to as chamber assembly) removed. In particular, FIG. 6 shows some of the internal components housing within base body 316 of base assembly 104, namely, magnet 606, light source 502, transducer 602 and blower outlet 604. The internal operation of humidifier 100 includes the use of a mist generator 602, such as a transducer, and at least one blower 718 to generate and move fine mist into the environment. Transducer 602 may be any device capable of creating fine mist from a fluid such as water. In the present example, transducer 602 is a piezoelectric device, such as a small disc, that vibrates at a high frequency, converting electrical energy into mechanical vibrations. These rapid mechanical vibrations generate cavitation at the fluid surface, creating a fine mist composed of micron-sized water droplets.

In operation, fluid from the tank 318 flows to transducer 602, regulated by the valve assembly 304. The transducer 602 then atomizes the fluid into fine mist. A mist baffle 704 may also be provided to control and direct the flow of fluid mist, preventing it from splashing out and ensuring efficient distribution. Mist baffle 704 can also help prevent minerals in the fluid from accumulating on surfaces, significantly reducing maintenance requirements and extending the effective operational life of transducer 602. Specifically, mist baffle 704 acts as a flow regulator and debris barrier, smoothing out mist trajectories to maintain a uniform upward plume, enhancing the stability and predictability of the illuminated mist column or chamber 302.

Simultaneously, a blower 718 positioned within the base assembly 104 generates a flow of air, which exits through a blower outlet 604 positioned adjacent to transducer 602. The air generated by blower 718 captures and entrains the mist produced by transducer 602 and propels the mist upward through chamber 302. The air-mist mixture travels through the illuminated chamber 302 and exits through the mist outlet 108 into the surrounding environment, thereby increasing the ambient humidity. The coordinated operation of transducer 602 and blower 718 ensures efficient mist production and dispersion, while also enhancing the visible effect of the illuminated mist column within chamber 302. Blower 718 may be a variable-speed fan configured to adjust airflow rates depending on operating conditions or user-selected settings, thereby modulating mist output volume, height, and turbulence. This enables dynamic adjustment of the mist stream's visual behavior—from a soft, gentle candle flicker to a more energetic, fire-like plume—thereby personalizing both the humidification and aesthetic performance according to user preferences or environmental conditions. Additionally, the active entrainment of mist within the airflow ensures that mist disperses effectively throughout the ambient space rather than settling near the device, improving room-wide humidification efficiency.

FIG. 7 is an exploded view of the humidifier of FIG. 1. As stated above, humidifier comprises of a tank assembly 102 supported by or removably seated above base assembly 104. Tank assembly 102 comprises of handle 110, attachments 112, 208, tank 318, chamber assembly comprising of chamber 302 and bottom plate 314, magnet cover 306 housing a magnet and shell 112. Base assembly 104 comprises of base body 316 that houses actuator 716, light source 502, blower 718, magnet 606 (which is separate from the magnet housed by magnet cover 306), sensor 722, a PCB/controller 720, transducer 602, bottom base plate 202 and a power source 724. In some examples, valve assembly 304 may be positioned in either the tank assembly 102 or the base assembly 104 depending on manufacturing preferences. The lighting assembly 702 comprises the combination of the light source 502 and chamber 302, forming a key aesthetic and functional component. Power source 724 may be one or more batteries, one or more rechargeable batteries, or an external power source such as an A C wall outlet. Power source 724 supplies electrical power necessary to operate all active components of humidifier 100, including transducer 602, blower 718, controller 720, sensor 722, and light source 502.

FIGS. 8-13 illustrate another example of a humidifier 800 of the present invention. It should be understood that all features and functions and/or combination of features and functions incorporated in humidifier 100 above may also be incorporated in humidifier 800 without departing from the scope of the invention. Similarly, all features and functions and/or combination of features and functions incorporated in humidifier 800 may also be incorporated in humidifier 100. The introduction of humidifier 800 highlights the modularity, scalability, and cross-compatibility of the inventive platform, demonstrating how the core principles of illuminated mist presentation and safe, efficient humidification can be adapted across different design aesthetics, form factors, and market segments, including both consumer-grade and premium, high-design variants.

FIG. 8 is a top perspective view of another example of an implementation of a humidifier 800 of the present invention. Similar to humidifier 100, humidifier 800 comprises of tank assembly 802 supported by or removably seated above base assembly 804. The tank assembly 802 comprises of a tank 1316 for holding a liquid (e.g., water) to be humidified and mist outlet 806 positioned on top side of tank 1316. In this example, tank 1316 itself (as opposed to shell 112) may include at least one or more decorative elements 808 for not only enhancing the aesthetic appeal of humidifier 800 but also to enhance the flickering flame or lantern effect of lighting assembly 1002.

FIG. 9 is a bottom perspective view of humidifier 800. FIG. 9 illustrates base assembly 804 comprising a bottom plate or cover 902. Similar to humidifier 100, humidifier 800 is configured as a portable, free-standing humidifier that permits it to be easily placed and operated on a variety of surfaces without requiring permanent installation, enhancing user convenience and device versatility.

FIG. 10 is a see-through top perspective view of humidifier 800. Tank 1316 of tank assembly 802 may be made of any transparent, translucent, semi-transparent or semi-translucent material known in the art for allowing lighting assembly within tank 1316, namely chamber 1320 to be seen externally by a user.

Similar to humidifier 100, chamber 1320 may include at least two open ends, where one end acts as a mist inlet and is in fluid communication with transducer 1204 within base body 1008 for receiving mist created by transducer 1204 and the other open end is a mist outlet 806 for expelling mist created by transducer 1204 from humidifier 800 through chamber 1320 and out from mist outlet 806.

Chamber 1320 may also be made of any transparent, translucent, semi-transparent or semi-translucent material known in the art for allowing both the light emitted within chamber 1320 and the mist that flows through chamber 1320 to be seen externally by a user. The combination of the light and mist that flows through chamber 1320 creates a flame or lantern-like effect. The valve assembly 1004 integrated into bottom plate 1010 for controlling the flow of fluid from tank assembly 802 to base assembly 804 may be the same and therefore, operate the same as valve assembly 304. As shown in FIG. 13, valve assembly 1004 generally comprises a plunger 1306 attached to a spring pin 1312, a cap gasket 1308, and a fill cap 1310.

FIG. 11 is a top perspective view of humidifier 800 with tank 1316 removed. Humidifier 800 also includes chamber 1320 that extends from bottom plate 1010 of tank 1316. Chamber 1320 may be formed as a tube or other elongated member that projects upward from the base assembly 804 and includes a top funnel 1318 having a mist opening 1006. The chamber 1320 is configured such that fluid contained within tank 1316 may surround at least a portion of the external surface of chamber 1320. Chamber 1320 includes at least two open ends, wherein a first open end acts as a mist inlet that is in fluid communication with the transducer 1204 to receive mist generated by the transducer 1204, and a second open end forms a mist outlet 1006 for expelling the mist through chamber 1320 and out of the humidifier 800. The inclusion of top funnel 1318 assists in smoothing and accelerating the mist's exit velocity, reducing turbulence at the chamber outlet and thereby preserving the columnar integrity of the illuminated mist as it rises into the ambient environment.

FIG. 12 is a top view of humidifier 800 with the tank assembly 802 removed. Similar to humidifier 100, humidifier 800 may also include magnet cover 1206 that is part of a magnetic detection system for verifying proper tank placement. Additionally, humidifier 800 includes an enhanced lighting and mist propulsion system. In this embodiment, four light sources 1202 are positioned within the base assembly 804, arranged around a transducer disc of a transducer 1204. The four light sources 1202 are equally spaced around the transducer 1204 to provide uniform and intensified illumination into the chamber 1320. This configuration results in a brighter, more vivid glow effect when light interacts with the mist traveling through the chamber 1320. The symmetrical radial arrangement of light sources 1202 ensures consistent illumination intensity from multiple angles, eliminating directional shadowing and creating a three-dimensional visual depth within the mist column or chamber 1320. Additionally, multiple light sources permit sophisticated lighting control, such as dynamic color cycling, flame flicker simulation, or patterned pulsing, enabling users to tailor the atmospheric effect according to personal mood, seasonal decor, or thematic settings (e.g., relaxation, romance, celebration).

In addition, humidifier 800 includes two blowers 1208 and 1210 rather than one. The first blower 1208 and second blower 1210 operate together to increase the volume and velocity of airflow directed through chamber 1320. The increased airflow not only helps propel the mist upward through chamber 1320 more efficiently but also contributes to a more dramatic visual effect, as the illuminated mist stream appears more dynamic and voluminous.

FIG. 8 is an exploded view of humidifier 800. As stated above, humidifier comprises of a tank assembly 802 supported by or removably seated above base assembly 804. Tank assembly 802 comprises of top cap 1314, tank 1316, chamber assembly 1002 comprising of top funnel 1318, chamber 1320, bottom plate 1010, mist tube cap 1322, and mist tube 1324. Base assembly 804 comprises of base body 1008 that houses basin 1302, light sources 1202, blowers 1208, 1210, magnet 1206, a PCB/controller 1304, transducer 1204, and bottom base plate 902. In some examples, valve assembly 1004 may be positioned in either the tank assembly 802 or the base assembly 804 depending on manufacturing preferences. The lighting assembly comprises the combination of the light source 1202 and chamber 1002 or chamber assembly 1002, forming a key aesthetic and functional component. A power source may also be provided for supplying electrical power necessary to operate all active components of humidifier 800.

The mist tube 1324 within chamber 1320 allows mist to be concentrated before it flows into chamber 1320. While in some examples, mist tube may be illuminated from within by light sources 1202, in other examples, mist tube 1324 may be positioned such that light sources 1202 are positioned outside of mist tube 1324. Such positioning allows only mist to enter the mist tube 1324 while the light emitted from light sources 1202 illuminates the exterior of mist tube 1324 and interior of chamber 1320. Such positioning of mist tube mitigates risk of mist obstructing the illumination of light sources by keeping the mist, at least initially, separated from light sources 1202. Such feature enhances illumination and flamer effect of humidifier 800. In particular, the physical separation between the initial mist plume and the light emission zones prevents optical scattering losses that would otherwise diminish brightness or visual definition. The mist tube 1324 thus acts as both a conduit for mist and a light modulation zone, intensifying the visual concentration of light around the mist core and amplifying the three-dimensional, flame-like appearance. This innovative arrangement materially enhances both the functional performance (mist delivery) and aesthetic output (visual spectacle) of humidifier 800.

In some examples of humidifier 800, chamber 1320 may further include a mist tube 1324 positioned within chamber 1320. The mist tube 1324 functions to concentrate and channel the mist generated by transducer 1204 before it fully enters and disperses into the broader interior space of chamber 1320. Mist tube 1324 may be aligned vertically with the mist outlet 806, 1006 and serves to guide the mist upward in a more focused stream.

In one example, mist tube 1324 may be internally illuminated by the surrounding light sources 1202. Alternatively, in another example, mist tube 1324 is positioned so that light sources 1202 are located outside of mist tube 1324. In this arrangement, the mist is initially contained within the mist tube 1324 while the light sources 1202 emit light that primarily illuminates the exterior of the mist tube 1324 and the interior surfaces of the surrounding chamber 1320. This strategic positioning of mist tube 1324 relative to light sources 1202 ensures that mist does not immediately obstruct the light output, thereby enhancing the optical clarity and brightness of the lighting effect. By initially isolating the mist from direct interference with light sources 1202, the illuminated environment within chamber 1320 is made more vivid and striking. This construction greatly enhances the simulated flame or lantern effect that is characteristic of the humidifier of the present invention, providing both an improved visual impact and enhanced mist dispersion performance.

As illustrated above, humidifier 100, 800 uniquely integrates a mist generation and mist illumination system that produces not only functional humidity output but also a visually aesthetic effect. The combination of the fine mist created by the transducer and the illumination provided by the light source within the transparent or translucent chamber creates a distinctive flame-like or lantern-like visual experience. This mist-light interaction is made externally visible through the chamber walls, enhancing user enjoyment and providing a decorative feature not found in conventional humidifiers. The mist flows dynamically upward through the glowing chamber, producing an enchanting visual effect while simultaneously delivering moisture into the ambient air, thus offering dual utility: functional air humidification and aesthetic room enhancement.
