CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Application No. 63/136,521, filed Jan. 12, 2021, the contents of which are incorporated herein by reference in their entirety. 
    
    
     TECHNICAL FIELD 
     This document generally describes devices, systems, and methods related to candle simulators. 
     BACKGROUND 
     Candles have traditionally included a wick that is lit to provide a flame that generates light. Wicks can be embedded in wax or other apparatus to hold the wick in place as it burns and emits light. Candles can be used for a variety of purposes, such as to illuminate dark environments (e.g., dark rooms) and/or to add an aesthetic appeal to a room or other setting. For example, a candle&#39;s flame can be ignited to provide aesthetic appeal within a room. 
     SUMMARY 
     The document generally relates to candle simulators, which can include devices and apparatus that simulate a candle flame without a wick (or other ignitable object) and without an actual flame. The disclosed technology can provide for realistic flame simulation in a manner that can generate the same (or better) aesthetic appeal of an actual candle without the use of an actual flame, which can improve user safety by reducing the risk of candles accidentally igniting other objects, such as in the case of an actual candle being knocked over and/or being placed too close to other flammable objects. 
     The disclosed technology can provide flame simulations that are highly realistic without the fire-related risks posed by actual candles. Realistic flame simulations can be generated by the candle simulation disclosed in this document through a variety of features. For example, a candle simulator can include an atomizer to atomize a fluid (e.g., water) that can be illuminated by one or more light sources to simulate a flame. However, channeling a flow of atomized fluid (e.g., water vapor, mist) to appear as a realistic flame, including flickering with changing intensities of light and concentration, is not trivial. To provide realistic flames, the disclosed candle simulators can include a blower that is configured to generate a flow of the atomized fluid that is directed through an aperture and the light sources can be positioned in and/or around the aperture to illuminate the atomized fluid. The atomized fluid can be channeled into a simulated flame by a chimney structure at the aperture and/or by one or more smaller holes that are formed in one or more portions of the chimney structure. A transparent enclosure (e.g., glass enclosure, plastic enclosure) can be configured to surround the simulated flame and to extend at least a minimum distance from the base of the simulated flame. Additional and/or alternate features can be used to generate realistic simulated flames. 
     The disclosed candle simulators can include a variety of additional features that are designed to mitigate and/or solve other issues that may be introduced by the use of candle simulators. For example, although candle simulators may not pose fire risks like traditional candles, they can include a reservoir of fluid (e.g., water) that may be possible to spill if the candle simulator is tipped over. The disclosed simulators solve and alleviate these (and other) issues, for example, by providing a spill-proof fluid reservoir that is configured to mitigate and/or stop water from seeping out of the reservoir when the candle simulator is tipped over. Additionally, the disclosed candle simulators can include one or more openings in a top surface of the candle simulator that can be used to conveniently refill the water reservoir without having to tip the simulator on its side and/or otherwise disassemble the candle simulator to gain access to the reservoir. Such openings in the top surface of the candle simulator can be covered up by one or more decorative components, though, which can maintain aesthetics of candle simulators while providing for enhanced functionality and use. 
     The disclosed candle simulators can include component that generate aromas and/or scents, which can also simulate aromas and/or scents that are generated by actual candles. For example, the disclosed candle simulators can include components that permit for scented fluid to be atomized and emitted from the candle simulator as atomized scented fluid (e.g., scented vapor, scented mist). Such components can include, for example, an additional atomizer and fluid reservoir to retain and atomize scented fluid, an additional fluid reservoir to retain and dispense scented fluid into a combined atomizer to atomize scented fluid together with a primary fluid (e.g., water) for the simulated flame, and/or a combined reservoir for scented fluid and a primary fluid that feeds an atomizer. In the case of an additional atomizer, the atomized scented fluid may be combined with the atomized primary fluid (e.g., water vapor) and emitted from the same aperture, and/or it may be separately emitted from one or more different apertures in the candle simulator. Scented fluids may be filled in a variety of ways, such as through refilling from a supply of scented fluid, through the use of replaceable scent pods, which may contain a volume of scented fluid, concentrated material that can be combined with the main fluid to generate scented fluid (e.g., dissolved), and/or other components. 
     The disclosed candle simulators can additionally and/or alternatively include additional features that are not present with actual candles, such as components to generate sound (e.g., embedded speaker), components to generate additional sources of light beyond the simulated flame, components to permit for remote control/operation of the candle simulators, and/or components to permit for coordinated operation among multiple different candle simulators. 
     The disclosed candle simulators can additionally and/or alternatively be designed to permit for efficient and cost effective manufacturing through the use of several swappable components that allow for a wide variety of designs to be readily achieved without requiring a vast number of different manufacturing lines. For example, the candle simulators can include a common module that contains the atomizer(s), fluid reservoir(s), blower, and/or lighting devices, which can be inserted into a variety of differently shaped, sized, and/or patterned outer housings. These outer housings can additionally include different design elements, such as different chimney designs, different top surfaces from which the chimneys extend, different transparent shields, and/or other components that can be readily combined to great a vast number of different candle simulators. 
     Particular embodiments described herein can include an apparatus for providing a simulated flame, the apparatus including a base housing, a flow generator contained within the base housing that can generate a flow of atomized fluid, a lid positioned on top of the base housing, the lid defining a main opening through which the flow of atomized fluid can be emitted, a chimney that can be positioned adjacent the main opening, the chimney extending upwards and that can focus, at least in part, the flow of atomized fluid into a channel of atomized fluid, and one or more light sources that can be positioned near the main opening to the lid that can illuminate the channel of atomized fluid to provide the simulated flame. 
     Such an apparatus can optionally include one or more of the following features. For example, the chimney can be attached to a top surface of the lid and that, at least partially, surrounds the opening, the chimney extending upward from the top surface of the lid, in which the chimney can focus, at least in part, the flow of atomized fluid into the channel of atomized fluid. One or more sidewalls of the chimney can also define one or more apertures that can promote, at least in part, the formation of the channel of atomized fluid by the chimney. The one or more sidewalls can extend orthogonally from the top surface of the lid. The one or more sidewalls can include one or more curved surfaces that can extend from the top surface of the lid. The one or more sidewalls can include one or more planar surfaces that can extend from the top surface of the lid. Moreover, the one or more sidewalls can taper from their attachment to the top surface of the lid to a terminal point above the top surface. 
     The apparatus can also include a transparent lid that can extend upward from a top surface of the lid, the transparent lid at least partially enclosing a volume that can contain the simulated flame. The transparent lid can define a first opening that can mate with the lid and a second opening that can be open to an ambient environment. In some implementations, the chimney can be part of the base housing. The chimney can also extend through the main opening to the lid. 
     As another example, the apparatus can also include a cloud chamber embedded inside the base housing and fluidically connected to the main opening to the lid and the flow generator, a liquid chamber embedded inside the base housing and positioned beneath a portion of the cloud chamber, and a valve positioned inside the base housing to fluidically separate the cloud chamber from the liquid chamber. The valve can prevent liquid from flowing from the liquid chamber into the cloud chamber. The valve can be a one-way valve. The valve can be a silicone valve. Moreover, the apparatus can include a fan embedded inside the base housing, the fan being configured to circulate the flow of atomized fluid from the flow generator through the cloud chamber and out through the main opening to the lid to provide the simulated flame. A speed of the fan can be adjustable so as to change an appearance of the simulated flame. A higher fan speed can increase the flow of atomized fluid to provide a stronger simulated flame and a lower fan speed can decrease the flow of atomized fluid to provide a slower simulated flame. 
     Particular embodiments described herein include an apparatus for providing a simulated flame that includes a base housing, a flow generator contained within the base housing that is configured to generate a flow of atomized fluid, a lid positioned on top of the base housing, the lid defining a main opening through which the flow of atomized fluid is configured to be emitted, a chimney that is attached to a top surface of the lid and that, at least partially, surrounds the opening, the chimney extending upward from the top surface of the lid and being configured to focus, at least in part, the flow of atomized fluid into a channel of atomized fluid, and one or more light sources that are positioned near the opening to the lid that are configured to illuminate the channel of atomized fluid to provide the simulated flame. 
     Such an apparatus can optionally include one or more of the following features. One or more sidewalls of the chimney can define one or more apertures that are configured to promote, at least in part, the formation of the channel of atomized fluid by the chimney. The one or more sidewalls can extend orthogonally from the top surface of the lid. The one or more sidewalls can include one or more curved surfaces that extend from the top surface. The one or more sidewalls can include one or more planar surfaces that extend from the top surface. The one or more sidewalls can taper from their attachment to the top surface of the lid to a terminal point above the top surface. The apparatus can further include a transparent lid that extends upward from the top surface of the lid, the transparent lid at least partially enclosing a volume that is configured to contain the simulated flame. The transparent lid can define a first opening that is configured to mate with the lid and a second opening that is configured to be open to an ambient environment. 
     In some embodiments, the candle simulation designs depicted in one or more of the figures. 
     The devices, system, and techniques described herein may provide one or more of the following advantages. For example, a top portion of the candle simulator can have apertures for creating a more realistic flame. The apertures can be angled and configured in such a way that when mist is expelled through the apertures and a light source illuminates the mist from below, the mist can have a more realistic flame-like appearance. 
     As another example, the candle simulator can be configured to glass lids of different heights to accommodate for different flame heights or types. In other words, the simulator can be fitted into a variety of differently sized containers and lids. A lid with a bigger height can be used advantageous where the candle simulator emits a larger faux flame. A lid with a smaller height can be advantageous where the simulator emits a smaller faux flame. Either lid can be fitted or attached to the simulator to accommodate a user&#39;s desired preferences. 
     As yet another example, the disclosed technology can provide for ease of use in refilling a water cartridge or tank of the candle simulator. A user can pour water through an opening in the top of the simulator. The opening can include a funnel for funneling the water into the cartridge so that the water does not spill out of the simulator or onto other components (e.g., electrical components) of the simulator. The opening can also include a meter line visible from a top of the simulator such that the user can easily see when they are filling water up to a capacity of the water cartridge or tank. 
     As another example, the disclosed technology can provide for reducing spillage of water from the candle simulator. The encasing and sealed top of the simulator can prevent water from spilling out of the water cartridge if the simulator is tipped over or otherwise not on a flat surface. The sealed top can be made of silicone and have a double lip lid around a top portion of the simulator&#39;s housing. This configuration can seal the simulator such that water within the simulator (e.g., inside the water cartridge or tank) may not spill out. 
     The disclosed technology can also provide for improved safety since the simulator does not generate a real flame. The simulator generates a realistic looking flame that can also emit a fragrance or other desired aroma. Since the simulator does not generate a real flame, the simulator may not create a fire hazard or other safety concern when used in an indoor or other setting. 
     The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.

     DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS 
     This document generally relates to candle simulators that generate realistic looking flames and, in some instances, includes a variety of additional features, such as components to emit aromas and/or other fragrances. Referring to  FIGS. 1A-B , an example candle simulator  100  with a lid attachment  104  is depicted.  FIG. 1C  depicts the lid attachment  104  for the candle simulator  100  of  FIGS. 1A-B . Referring to  FIGS. 1A-C , the simulator  100  can include a sleeve  102 , the lid attachment  104 , a top surface  106 , and a transparent lid  108 . The sleeve  102  can be decorative and can come in any of a variety of different patterns, designs, shapes, and/or sizes, and can combined with the lid attachment  104  to provide a base for the candle simulator  100 . One or more components to generate a realistic flame simulation can be contained within such a base, such as through the use of a cartridge including components to generate a flow of atomized and illuminated fluid. The sleeve  102  and the lid  104  can be provided in any of a variety of designs that can be wrapped around the cartridge, which can permit for a variety of different candle simulator designs to be achieved through different sleeve  102  and/or lid  104  combinations while using the same cartridge/internal components. 
     The top surface  106  can include a chimney  110  with a main aperture/opening through which flow of atomized fluid (e.g., water vapor) is emitted via a blower contained within the candle simulator  102 . The atomized fluid can be illuminated by one or more lights that are positioned inside of or near the chimney  110 , which can provide a simulated flame feature. The chimney  110  can include a variety of additional and smaller shaped apertures in its sidewall to promote the formation of a flow of atomized fluid that, when illuminated, provides a realistic flame simulation. The apertures in the sidewalls of the chimney  110  can, for example, promote a central column of atomized fluid to be projected through the opening/main aperture while minimizing pockets of lower pressure adjacent to the opening and near the top surface  106 , which can avoid pressure-based short-cycling that would cause the centralized column of atomized fluid to spill over onto the surface. By being able to provide and maintain a centralized and focused column of atomized fluid above the main opening of the chimney  110  (through the use of the chimney  110  and its sidewall apertures, for example), the simulated flame can appear more realistic and can retain its realistic flame appearance for extended durations. The lid attachment  104 , its top surface  106  and/or chimney  110  can be made from any of a variety of materials, such as metal materials, wood materials, silicon materials, plastic materials, and/or others. An example material can be aluminum, but any other lightweight metal material can be used. The components of the lid attachment  104  can be constructed from separate components and/or materials, as well. For example, the chimney  110  can be integrated into and/or attached to the surface  106 . 
     The transparent lid  108  can be configured to be connected to (e.g., attach, rest on top of) the sleeve  102  and/or the lid attachment  104  so as to enclose (fully and/or partially) a volume around the simulated flame being emitted through the chimney  110 . The transparent lid  108  can be any of a variety of shapes, such as a tube (e.g., straight tube, curved tube, tapered tube), a structure with one or more straight sides (e.g., box, cube, tube with one or more straight sides), irregular shapes, and/or others. The transparent lid  108  can be open at the bottom to receive the simulated flame and the sleeve  102 /lid attachment  104 . The transparent lid  108  can include one or more other openings to permit for the atomized fluid to be evacuated from the candle simulator and to permit for airflow to recirculate into the areas adjacent to the chimney  110  (to avoid pockets of low pressure). The transparent lid  108  may be configured to be spaced apart laterally from the chimney  110  so as to permit for airflow around the central channel of atomized fluid that is forming the simulated flame. The transparent lid  108  can be made of any of a variety of materials, such as glass (e.g., hurricane glass), plastic, and/or other at least semi-transparent materials. The lid  108  can also be in varying heights. A higher lid  108  can provide for a higher flame while a lower lid  108  can provide for a lower flame. A user can choose which size lid  108  to use to achieve a desired flame height. The sleeve  102  can come in different patterns, sizes, textures, and/or colors. 
       FIG. 1D  depicts removing the lid attachment  104  from the candle simulator  100  of  FIGS. 1A-C . The top surface  106 , the transparent lid  108 , and the lid attachment  104  can be sealed or attached together. As shown, the lid attachment  104  can be removed or detached from the sleeve  102  such that a simulator module  200  is accessible. The simulator module  200  can house one or more components that are used for generating the realistic-looking flame and/or emitting an aroma or other fragrance, as described further below. The simulator  200  can include openings  202  and  220 . The opening  202  can be configured to mate with the chimney  110  such that the mist can flow from within the module  200  and through the chimney  110 . The mist can be illuminated by lighting features through this flow path. The opening  220  can also be configured for receiving water to fill a water tank or cartridge within the module  200 . A user can therefore remove the lid attachment  104  to access the water cartridge of the module  200  and fill the cartridge with water. The user can then replace the lid attachment  104 , thereby sealing the water within the water cartridge to avoid from spilling. 
       FIG. 2A  depicts a candle simulator module  200  that can be placed within different candle simulator housings  204  and  100 . The module  200  can fit into a silicon lid attachment housing  204 . The module  200  can also fit into the simulator housing  100  having the lid attachment  104  described herein (e.g., refer to  FIGS. 1A-D ). 
     The housing  204  can include a glass lid  208  and a sleeve  206 . The glass lid  208  and/or the sleeve  206  can be the same or similar to the transparent lid  108  and/or the sleeve  102  of the housing  100 . Moreover, as depicted, the housing  204  can include a metal plate chimney  210  configured to a silicon cap  212 . The glass lid  208  can also be configured to the silicon cap  212 . When the silicon cap  212  is removed or otherwise detached from the sleeve  206 , the glass lid  208  can also be removed so that the user can access components of the module  200  (e.g., fill the water cartridge of the module  200  with water). The opening  202  can also be aligned with the metal plate chimney  210 . The metal plate chimney  210  can be removably connected to the silicon cap  212 . For example, the chimney  210  can be screwed, bolted, or otherwise fastened to the silicon cap  212 . The chimney  210  can optionally be replaced with other chimneys, which can provide for variation in flame type, size, and style. 
       FIG. 2B  depicts an example candle simulator with the silicon lid attachment  204 . The sleeve  206  can be a variety of different colors, styles, sizes, and/or textures, as depicted and described herein. As shown, a faux flame is emitted through the metal cap  210  that is fastened to the silicon cap  212 . The glass lid  208  is a shorter height than other glass lids depicted and described herein, which can provide for a wider and/or shorter faux flame. Glass lids of one or more other sizes/heights can be configured to the simulator  204  to provide for the user&#39;s desired flame style and/or height. 
       FIG. 2C  depicts example configurations of the candle simulator  100  with the lid attachment  104  described herein. As shown, the simulator  100  can come in a variety of sizes, such as a small  240 , a medium  250 , and a large  260 . The simulator  100  can also have a variety of textures, patterns, and/or colors. Although not depicted, the candle simulator with the silicon lid attachment  204  can also come in similar sizes (e.g., small, medium, and large). In some implementations, the simulators  100  and/or  204  can also have different sized glass lids  108  and  208 . For example, the simulator  100  can be in the medium size  250  with the transparent lid  108  having a longest height. 
       FIGS. 3A-B  depicts the simulator with the silicon lid attachment  204  and the metal plate chimney  210  for the example candle simulator of  FIG. 2B . As shown in  FIG. 3A , the silicon cap  212  can attach to the sleeve  206 . The chimney  210  can be configured to the silicon cap  212 . In other implementations, the chimney  210  can be configured to the module  200  (e.g., fastened/bolted). The silicon cap  212  can have an opening configured to encircle or enclose the chimney  210  that is configured to the module  200 . 
     As shown in  FIG. 3B , once the silicon cap  212  is removed, a top surface  215  of the module  200  can be exposed. The metal plate chimney  210  can be retained to the top surface  215  of the module  200 . For example, the chimney  210  can be bolted or fastened to the top surface  215  using one or more screws, bolts, or fasteners. Bolting the chimney  210  to the top surface  215  of the module  200  can be advantageous to configure the module  200  to different housings. For example, the chimney  210  can be removed so that the module  200  can be fitted into the simulator  100  having the lid attachment  104 . Bolting the chimney  210  to the module  200  can be advantageous to configure the module in the simulator with the silicon lid attachment  204 . 
     In other implementations, the chimney  210  can also be configured to the top surface  215  during manufacturing of the module  200 . In other words, the chimney  210  may not be removable from the top surface  215 . This can be advantageous where the module  200  is configured to fit within the simulator with the silicon lid attachment  204 . 
       FIG. 3C  depicts components of the candle simulator with the silicon lid attachment  204  of  FIG. 2B . In some implementations, one or more components of the simulator  204  can be configured or attached together (e.g., at manufacturing). For example, all components  212  and  206  can be attached together except for the glass lid  208 . As shown, the silicon cap  212  can have a lip or protruding edge  214 . The edge  214  can secure around a top of the sleeve  206  to prevent water from spilling when the water cartridge within the module  200  is filled. 
     The silicon cap  212  can have an opening  217  for receiving or fitting around the metal plate chimney  210 . Once the silicon cap  212  is removed or detached from the sleeve  206 , the top surface  215  of the module  200  can be exposed. The top surface  215  can include the opening  220 , which can be connected to the water cartridge and used to fill the water cartridge with water, as well as the chimney  210 , and openings  218 A-N. The openings  218 A-N can include an IR window for an infrared receiver sensor and one or more LED spots. For example, the IR window can provide a viewing of light that indicates whether a remote control is in communication (e.g., wireless and/or BLUETOOTH) with the module  200 . For example, the remote control can be connected to the module  200  so that the user can adjust one or more features or characteristics of a faux flame. The IR window can also include a sensor (e.g., infrared receiver sensor) or other type of receiver that can be used to connect the remote control to the module  200 . In some implementations, the LED spots can indicate a battery of the module  200 . For example, if the module  200  uses a rechargeable battery, once the rechargeable battery needs to be charged and/or replaced, the LED spots can change colors. A green color can be associated with full charge, an orange color can be associated with half charge, and a red color can be associated with a low charge. 
     As depicted, the silicon cap  212  can have an opening  219  that corresponds to a position and size of one or more of the openings  218 A-N in the top surface  215  of the module  200 . In the example of  FIG. 3C , the opening  219  is configured to match the position and size of the IR window. Light from the LED spots (e.g., other openings  218 A-N) can be configured bright enough to shine through the material of the silicon cap  212 . As a result, the silicon cap  212  may not require additional openings like the opening  219  that match or correspond to all the openings  218 A-N. 
       FIG. 3D  depicts removing components of the candle simulator with the silicon lid attachment  204  of  FIG. 2B . As shown, the silicon cap  212  can be snapped onto or sealed onto the top of the sleeve  206 . The glass lid  208  can also be placed over the silicon cap  212  around edges of the cap  212  such that the lid  208  is flush with the edge of the sleeve  206 . In other words, the lid  208  may not extend or protrude out from sides of the sleeve  206 . This can provide for an aesthetic and appealing appearance. 
     The glass lid  208  can be removed. The silicon cap  212  can then be snapped or peeled off of the top of the sleeve  206 . The cap  212  can be peeled off using the edge  214 , which can be configured to secure around a top edge of the module  200  once it is placed inside the sleeve  206 . Peeling off the silicon cap  212  can reveal a first portion  228  of an underside of the silicon cap  212  as well as the module  200 . As described throughout this disclosure, once the silicon cap  212  is removed, the user can access components of the module  200 , such as the water cartridge. 
       FIG. 3E  depicts a bottom view of the silicon cap  212  described herein. In this example, the underside of the silicon cap  212  has the first portion  228  and a second portion  226 . In some implementations, both portions  226  and  228  can be lifted or bent to peel the cap  212  off of the housing  206 . In other implementations, the first portion  228  can be lifted or bent to peel the cap  212  off of the housing  206 , as depicted in  FIG. 3D . Moreover, the cap  212  includes the opening  217 , configured to receive the metal chimney  210 . The cap  212  can optionally include openings  219 A-N that are positioned and a same size as the openings  218 A-N in the module  200 . For example, one or more of the openings  219 A-N can be positioned and aligned with the LED spots and/or the IR window described herein. As shown in other implementations, the silicon cap  212  can have one opening  219  configured to align with the IR window of the module  200 . Lights emitted from the LED spots on the module  200  can then filter through the material of the silicon cap  212 . 
     The silicon cap  212  has the lip or undercut  214 , which can be configured to position on or encircle a protrusion of a top surface of the module  200 . Once the silicon cap  212  is positioned over the module  200 , the lip  214  can seal contents of the module  200  within such that the contents do not spill out from the module  200  (e.g., refer to  FIG. 3F ). For example, if the water cartridge is filled with water, when the silicon cap  212  is positioned over the module  200 , even if the module  200  is tipped over, the water may not spill out. The cap  212 &#39;s lip  214  can create a sealed barrier. 
       FIG. 3F  depicts attachment of the silicon cap  212  to the candle simulator  204 . As shown, the module  200  has a housing  636 . The housing  636  has a protrusion  227  at the top surface of the module  200 . The silicon cap  212  can be positioned over the protrusion  227  and the lip  214  can seal around the protrusion  227  to create a barrier. This barrier can prevent water from spilling out of the water cartridge of the module  200 , as described herein. 
       FIG. 3G  depicts attachment of the lid attachment  104  to the candle simulator  100 . A rubber gasket  127  can be positioned between the metal lid  104  and an edge or side of the protrusion  227  of the module  200 . This configuration can be advantageous to prevent water from spilling out of the water cartridge within the housing  636  of the module  200 . In other words, the metal plate  104  and the rubber gasket  127  can form a sealed barrier similar to the barrier of the silicon cap  212  described throughout this disclosure (e.g., refer to  FIG. 3F ). 
       FIG. 4  depicts an example candle simulator module  200  of  FIG. 2A .  FIGS. 10A-C  also depict the candle simulator module  200 . Referring to the  FIGS. 4 and 10A -C, the module  200  can include a cable  222  for charging the module  200 . The cable  222  can be a USB or other cable that can be used to charge an internal power source of the module  200 . Therefore, the module  200  can be operated using the internal power source. The module  200  can also be operated while the cable  222  is plugged in and charging the module  200 . The module  200  can also include a sleeve  216  having a flange  223  to support various materials of the sleeves  106  and/or  206  described throughout this disclosure. Moreover, the opening  220  can take up a larger area or portion of the top surface  212  to make it easier for the user to fill the water cartridge with water. Moreover, water can be funneled through the opening  220  more easily since the opening  220  is larger and inclined downwards (e.g., sloped) towards the water cartridge within the module  200 . 
       FIG. 5A  depicts a bottom view of the candle simulator module  200  described herein. The module  200  can be positioned within the sleeve  106 . In other implementations, the module  200  can be positioned within one or more other sleeves (e.g., the sleeve  206 ). As shown in  FIGS. 5A and 10A , the module  200  includes a bottom cap  502 . In some implementations, the bottom cap  502  can be made of a metal material. The bottom cap  502  can also have a flange (e.g., the flange  223  in  FIG. 4 ) that is configured to support the outer sleeve  106 . In some implementations, the flange can be a 2 mm surface. The bottom cap  502  also includes legs  506 A-D. The legs  506 A-D can be rubber. The legs  506 A-D can be used to elevate the module  200  above a surface such that air can flow in through the bottom cap  502  via air openings  504 . The air openings  504  can be hidden from view on the bottom cap  502  to provide a more decorative and aesthetically appealing module  200 . The promotion of air flow described herein can be advantageous to generate mist and a faux flame, as described further below. The module  200  further includes the cable  222 . The cable  222  can be removably attached to a port (e.g., DC Port) in the bottom cap  502 . For example, once an internal battery source of the module  200  is charged, the cable  222  can be removed such that aesthetic appeal of the candle simulator may not be diminished. As another example, the candle simulator can be used while the cable  222  is attached to the module  200  and providing power to one or more components of the module  200 . Since the module  200  can be elevated off the surface by the legs  506 A-D, the cable  222  may not cause the module  200  to be off-balance or otherwise not leveled. The cable  222  can be positioned in a space between the surface that the module  200  is resting on and the flange or portion of the bottom cap  502  that is flush with the outer sleeve  106 . 
     As shown in  FIG. 10A , the bottom cap  502  can also include a switch  520  and a DC port  522  (e.g., refer to  FIGS. 6A-C ). The switch  520  can be a button or other switch that can be turned on and off to actuate the module  200  and components therein. The DC port  522  can be configured to receive the cable  222  to power the module  200  and/or charge an internal power source of the module  200 . 
       FIG. 5B  depicts a bottom view of the candle simulator module  200  with cable management  510 . In comparison to the module  200  of  FIG. 5A , the module  200  of  FIG. 5B  includes the cable management  510 . The cable management  510  can be a hook, fastener, clip, or other similar means configured to retain a portion of the cable  222  to the bottom cap  502 . As a result, the cable  222  may not move around and may instead be routed in a desired configuration to maintain aesthetic appeal. The cable  222  can also be routed using the management  510  away from the air openings  504  to ensure that an optimal amount of air can flow through the openings  504  and into the module  200 . The cable  222  can also be routed using the management  510  in such a way to avoid the cable  222  from accidentally being positioned under one of the legs  506 A-D when the module  200  is standing and/or being used to generate a faux flame. 
       FIGS. 6A-B  are schematic cutout side views of an example candle simulator  100 . 
       FIG. 6C  is a cutout side view of components of the candle simulator  100  having the lid attachment  104 . Referring to  FIGS. 6A-C , the module  200  has one or more components. A power switch  600  is positioned on a base  638  (e.g., bottom cap  502  in  FIGS. 5A-B ). The switch  600  can also be a button or other actuator to turn on one or more components of the module  200  to simulate a faux flame. The base  638  can also include a DC socket  602  configured to receive the cable  222 , as described herein. The base  638  can also include an air intake  604  (e.g., air openings  504  in  FIGS. 5A-B ). The air intake  604  can be configured to suck in or bring in ambient air from an external environment. Air can flow through an air channel  606  and can be dispersed through a cloud chamber  620  and a wind hole  610  via a fan  608 . The air can flow into the cloud chamber  620  via an inner air outlet  612  and by the fan  608 . 
     The user can fill a water tank  618  (e.g., water cartridge) by pouring water through a water fill hole  626  (e.g., the opening  220  described throughout this disclosure). In some implementations, the tank  618  can be a D180×H65 mm. One or more other tank configurations or tanks can be incorporated into the module  200 . The water can filter through a funnel  628 , which siphons the water into the tank  618 . A buoy  630  can be positioned within the funnel  628  as a gauge for the user to determine how much water is in the tank  618 . The buoy  630  can have a flat end that floats inside the tank  618  that can seal off an opening in the tank  618  where the water filters in from the funnel  628 . A water level sensor  622  can also be configured within the tank  618  to determine a fill level of the tank  618 . When the tank  618  is filled, the buoy  630  can be pushed up against the opening in the tank  618  where the water filters in from the funnel  628 . This can cause the tank  618  to be sealed off from receiving additional water. When the buoy  630  pushes up against the opening in the tank  618 , the user can see the buoy  630  protruding from the water fill hold  626 , which can indicate that the tank  618  is full and no more water should be added. In some implementations, when the water level sensor  622  detects that the tank  618  is full, the sensor  622  can communicate a signal to one of the LED spots positioned on a main PCB board  634 . The LED spot can be illuminated a color indicative of a water fill level. For example, the LED spot can glow green when the tank  618  is full. The LED spot can glow red when the tank  618  is empty. 
     The tank  618  can include a spilling water gate  632 . The gate  632  can be configured to prevent water inside the tank  618  from spilling out into the air chamber  606  or other components of the module  200 . The tank  618  can also include a water suction stick  616 . The water suction stick  616  can be configured to suction or pull water from the tank  618  and up into the cloud chamber  620 . An atomizer plate  614  can be positioned at a top of the water suction stick  616 . The atomizer pate  614  can be configured to generate mist in the cloud chamber  620  using the air brought in via the air channel  606  and the water brought in via the water suction stick  616 . The generated mist can be propagated around in the cloud chamber  620 , through the wind hole  610 , and out through a nozzle  624 . As described above, the fan  608  can create a flow path for the mist such that the mist propagates out of the nozzle  624 . 
     Still referring to the  FIGS. 6A-B , the main PCB board  634  can include the LED spots and/or the IR sensor described above. The board  634  can also be configured to an LED group  640 . The LED group  640  can include one or more LED lights that are directed up towards the nozzle  624 . The LED group  640  can also be positioned such that each of the lights in the LED group  640  illuminate the generated mist at different angles along a flow path for the mist from the cloud chamber  620 , through the wind hole  610 , and out through the nozzle  624 . For example, the lights in the LED group  640  can be positioned at different angles (e.g., one can be directed towards a right side of the nozzle  624 , another can be directed towards a left side of the nozzle  624 , and another can be directed at a top opening of the nozzle  624 ). As the generated mist is propagated out through the nozzle  624 , the mist and light from the LED group  640  can be dispersed through apertures, holes, or other openings in the chimney  110 . This can provide a more realistic looking flame than if the generated mist is propagated through a central opening. The various differently shaped, positioned, and/or sized apertures in the chimney  110  can be advantageous to form the flame and/or create differently designed or shaped flames. 
     In some implementations, the module  200  can also emit a fragrance or other aroma or scent. For example, a fragrance can be added to water that is filtered through the funnel  628  into the tank  618 . When mist is generated, the fragrance can then be emitted or dispersed along with the mist through the nozzle  624 . As another example, the module  200  can be configured to provide for separate water nebulization and fragrance nebulization. For example, a twist and lock cartridge can be used to contain a fragrance. Mist can be generated using the water in the tank  618  and another mist can be generated using the fragrance in the cartridge. The two mists can be combined and expelled through the nozzle  624 . The two mists can also be separately expelled through the nozzle  624  or two different openings. For example, the fragrance can be expelled through openings in the base  638 . The fragrance can also be expelled through an opening in the top surface  106  that is different from the nozzle  624  and/or the chimney  110 . As yet another example, the top surface  106  can have a spout or opening for the fragrance that is separate or different than the water fill hole  626 . The fragrance can flow into a tank that is separate or different than the water tank  618 . Moreover, the fragrance can be atomized using an atomizer plate that is separate or different than the atomizer plate  614 . Once the fragrance and water are atomized separately, they can be mixed together in the cloud chamber  620  and expelled out through the nozzle  624 . As mentioned, the atomized fragrance and water can also be separately moved through the module  200  and out through different openings. A fan that is separate or different than the fan  608  can be used to direct the fragrance through openings in the module  200 . 
     In other implementations, the module  200  can generate heat from the faux flame. Therefore, the module  200  can include a digital temperature control. The module  200  can have a thermostat (e.g., temperature sensor) and a display (e.g., LCD, LED, OLED, etc.) that can be configured to display a temperature of the generated flame. The user can adjust an amount of heat that is generated by the flame based on viewing the displayed temperature. In some examples, the temperature can be displayed on a remote control that is in communication with the module  200 . The user can then adjust the temperature of the flame using the remote control. In other examples, the temperature can be displayed on a mobile device (e.g., cellphone, smart phone, tablet, laptop, computer, etc.) via a mobile application from which the user can also adjust or moderate temperature of the flame. 
     In yet other implementations, the faux flame can be adjusted based on fan speed. Adjusting fan speed can cause the flame to be tamed (e.g., smaller), maxed out (e.g., larger), and/or any strength in between. For example, the flame can be increased in height by increasing speed of the fan  608 . The flame can also be made narrower by increasing speed of the fan  608 . As another example, the flame can be decreased in height or made wider by decreasing speed of the fan  608 . In some implementations, adjusting fan speed can also effect an amount of heat generated by the flame. The user can adjust fan speed using the remote control or the mobile application on the mobile device, as described above. 
       FIG. 7  is a schematic cutout side view of the candle simulator  100  having the lid attachment  104 . The lid attachment  104  has the chimney  110  configured with various apertures of differing sizes. When generated mist is propagated out through the nozzle  624  and illuminated by the LED group  640 , the mist can propagate through the apertures in the chimney  110  to look like a realistic flame. 
       FIG. 8A  is a top down view of the candle simulator having the silicon lid attachment  204 . Generated mist can be propagated through the nozzle  624 , up through the wide opening of the metal plate chimney  210 , and also out through sides of the metal plate chimney  210 . As depicted and described throughout this disclosure, sides of the chimney  210  can have apertures of varying sizes and shapes to provide for a more realistic-looking flame. In this example candle simulator with the silicon lid attachment  204 , the LED group  640  has five LED lights. In other example candle simulators (e.g., refer to  FIG. 6A ,  FIG. 8B ), the LED group  640  can have three LED lights. In yet other example candle simulators, the LED group  640  can have one or more additional or fewer LED lights. 
       FIG. 8B  is a top down view of the candle simulator  100  having the lid attachment  104 . Generated mist can be propagated through the nozzle  624 , up through the top opening of the chimney  110 , and also out through sides of the chimney  110 . As depicted and described throughout this disclosure, sides of the chimney  110  can have apertures of varying sizes and shapes to provide for a more realistic-looking flame. In this example candle simulator  100 , the LED group  640  has three LED lights. 
       FIG. 9  is an exploded top down view of the metal plate chimney  210  and components of the candle simulator module  200 . In this example, the LED group  640  has three LED lights. the LED lights of the group  640  are directed up towards the wide opening in the metal plate chimney  210 . Generated mist can flow from the cloud chamber  620 , around the LED group  640 , through the nozzle  624 , and out through the wide opening and apertures of the chimney  210 . The LED lights of the group  640  can generate light of different colors, brightness, and/or intensity along the flow path of the mist, thereby illuminating the mist to create a realistic faux flame. 
       FIGS. 10A-B  depict the candle simulator module  200 .  FIG. 10C  depicts a top view of the candle simulator having the silicon lid attachment  204 . As described in reference to the previous FIGS and as shown in  FIGS. 10A-C , water can be added to the water tank (e.g., the tank  618  in  FIGS. 6A-C ) through the opening  220 , down the water fill hole  626 . The buoy  630  can raise closer to the top of the hole  626  or the opening  220  to indicate a maximum fill of the tank. For example, a maximum line can be drawn along a side of the hole  626 . Then the top of the buoy  630  raises to the maximum line, the user can see that the tank is filled with water and no more water should be added. 
     In the example of  FIGS. 10A-C , the LED group has five LED lights that can shine light through the nozzle  624  to illuminate mist that propagates out through the nozzle  624  and the metal plate chimney  210 . The silicon cap  212  can also have openings  219 A-N through which LED lights from the IR window and/or LED spots  218 A-N of the module  200  can be outputted or displayed. 
       FIG. 11  depicts the candle simulator module  200  when tipped at an angle. As described throughout this disclosure (e.g., refer to  FIGS. 6A-C ), the module  200  can be sealed in such a way that water from the water tank may not spill out of the module  200 . Therefore, the module  200  can be tipped in one or more different directions and the water can remain within the tank of the module  200 . 
       FIGS. 12A-C  depict an example candle simulator  100  with an insertable fragrance bottle  700  that can add fragrance to the water tank  618  and simulated flame.  FIG. 12A  is a bottom view,  FIG. 12B  is a side view, and  FIG. 12C  is a perspective view of the example candle simulator  100  with insertable fragrance bottle  700 . The candle simulator  100  that is depicted can include an opening  702  in a bottom surface that is configured to receive and retain the fragrance bottle  700  in fluid communication with the water tank  618 . For example, the opening  702  can include a threaded portion that mates with an a opposite threaded portion on the fragrance bottle  700  to form a fluid seal (retaining fluid within the water chamber  618 ). The fragrance bottle  700 , for example, can be twisted and locked into place via the opening  702  in the example candle simulator  100 . The fragrance bottle  700  can include one or more apertures or water permeable surfaces/components that permit for fragrances (e.g., fluids, objects, material) contained in the bottle  700  to be dissolved in and/or to otherwise combine with the fluid in the water chamber  618 , which can cause for the simulated flame to include fragrance. The fragrance bottle  700  can be removable and refillable, and/or can be disposable and replaceable with other bottles  700 . For example, the bottle  700  can be a consumable cartridge that is purchased in different fragrances and intensities. In another example, the bottle  700  can be refillable by the user and can permit the user to add different fluids and/or fragrant objects (e.g., fruits, flowers, spices) into the bottle  700  to infuse fragrances into the water chamber  618 . Other configurations for adding fragrance are also possible, such as having a separate fragrance atomizer that is included in the module. 
     The disclosed technology can be considered an electromechanical domestic appliance nesi, with a self-contained electric motor, such as in Harmonized Tariff Schedule (HTS) Code 8509.80.50. 
       FIG. 13  is a schematic cutout side view of an example candle simulator  1300 . The candle simulator  1300  can operate and function similarly to the candle simulators described throughout this disclosure. The candle simulator  1300  can include a housing  1301 , a main PCB board  1302 , an air pipe  1303 , a cloud chamber  1304 , an air outlet  1305 , a fan  1306 , a valve  1307  (e.g., silicone), a water tank or other fluids tank  1308 , a DC power socket  1309 , a button switch  1310 , a nozzle  1311 , a water fill hole  1312 , a water funnel  1313 , an inner chamber outlet  1314 , an atomizer  1315 , a water suction stick  1316 , a water level sensor  1317 , and a bottom holder  1318 . The nozzle  1311  can be sized such that a light shining through the nozzle  1311  can appear brighter, thereby improving a flame effect of the candle simulator  1300 . The nozzle  1311 , which may be considered a chimney by itself and/or in combination with a portion of a lid, and can focus the flow of gas from the cloud chamber so that it has the appearance of a flame (e.g., flame effect), particularly when illuminated by one or more lights  1320  that are positioned adjacent and/or below the nozzle. The nozzle  1311  can be configured to extend above a top surface  1322  of the housing  1301  so as to mate with a corresponding opening in the lid (not depicted). The nozzle  1311  can, for example, extend above the top surface  1322  by a sufficient amount so that it is flush with a top surface of the lid, extends above the top surface of the lid, and/or is positioned below a top surface of the lid when the lid is positioned on the housing  1301 . Moreover, the fan  1306  can be adjusted to one or more different speeds. A higher speed, for example, can result in an improved, realistic flame effect while a slower speed can result in a smaller flame effect. 
     Unlike the candle simulators previously described in this disclosure, the candle simulator  1300  includes the valve  1307  instead of a buoy that passes through the water fill hold  1312  (refer to the buoy  630  in  FIGS. 6A-B ). The valve  1307  can be configured to operate similarly to the buoy described herein. For example, the valve  1307  can be configured to prevent water or other fluids, including but not limited to water vapor, from transferring between the water tank  1308  and the cloud chamber  1304 . Thus, the valve  1307  can fluidically separate the water tank  1308  from the cloud chamber  1304 . The valve  1307  can be a one way valve, in some implementations. As a result, water or other fluids may only flow down from the cloud chamber  1304  into the water tank  1308 . 
       FIG. 14  depicts a front view of an example candle simulator  1400  without a transparent lid. The candle simulator  1400  operates and functions similarly to the candle simulators described throughout this disclosure. For example, the candle simulator  1400  can be the candle simulator  1300  or any other candle simulators described herein. However, unlike the candle simulator  100 , a chimney (such as the chimney  110  described in  FIGS. 1A-C ) can be embedded inside the candle simulator  1400  instead of protruding above a top surface  1402  of the candle simulator  1400 . The chimney (not depicted) can therefore be aligned with an opening  1404  in the top surface  1402  of the candle simulator  1400  through which a realistic faux flame is emitted. Moreover, the candle simulator  1400  may not include a transparent lid, such as the transparent lid  108  of the candle simulator  100  (refer to the transparent lid  108  described in  FIGS. 1A-D ). 
     While this specification contains many specific implementation details, these should not be construed as limitations on the scope of the disclosed technology or of what may be claimed, but rather as descriptions of features that may be specific to particular embodiments of particular disclosed technologies. Certain features that are described in this specification in the context of separate embodiments can also be implemented in combination in a single embodiment in part or in whole. Conversely, various features that are described in the context of a single embodiment can also be implemented in multiple embodiments separately or in any suitable subcombination. Moreover, although features may be described herein as acting in certain combinations and/or initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a subcombination or variation of a subcombination. Similarly, while operations may be described in a particular order, this should not be understood as requiring that such operations be performed in the particular order or in sequential order, or that all operations be performed, to achieve desirable results.
