A removable diffuser cover comprises one or more decorative features. A cavity in a diffuser cover is shaped to receive a complete diffuser. A complete diffuser comprises a diffuser element that disperses a liquid into air within a diffuser chamber and a lid shaped to at least partially enclose an upper opening of the diffuser chamber. One or more openings are positioned to receive a dispersed liquid from a lid of a complete diffuser within a cavity and to allow the dispersed liquid to pass to an exterior of a removable diffuser cover. ## Claims ### Claim 1 An apparatus comprising: a removable diffuser cover comprising one or more decorative features; a cavity open in a bottom surface of the removable diffuser cover, the cavity shaped to receive a full height of a diffuser down to a base of the diffuser, the diffuser comprising a diffuser housing enclosing a diffuser element that disperses a liquid into air within a diffuser chamber and a lid shaped to at least partially enclose an upper opening of the diffuser chamber, the lid comprising an inner surface sloping inward and upward away from a center of the diffuser chamber equally on all sides to form a single aperture disposed in a center of the lid such that the lid comprises a splash guard, the splash guard adapted to slow the liquid from spilling out of the diffuser chamber when the diffuser is tipped or overturned during use, wherein the splash guard includes a convex surface and the convex surface is positioned between the removable diffuser cover and the diffuser chamber such that the dispersed liquid flows between the convex surface of the splash guard and the inner surface of the lid to the single aperture of the lid; one or more openings in the removable diffuser cover, the one or more openings positioned to allow the dispersed liquid to pass from the single aperture of the lid of the diffuser to an exterior of the removable diffuser cover. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the removable diffuser cover further comprises an electrical interface configured to electrically couple to an electrical interface of the diffuser. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the one or more decorative features comprise one or more interactive elements configured to be in electrical communication with the diffuser through the electrical interface of the removable diffuser cover. ### Claim 4 (depends on 1) The apparatus of claim 1, further comprising the diffuser, the one or more decorative features of the removable-diffuser cover having a different external shape than the diffuser. ### Claim 5 (depends on 4) The apparatus of claim 4, further comprising a controller configured to control one or more operations of the diffuser. ### Claim 6 (depends on 5) The apparatus of claim 5, further comprising an electrical interface between the removable diffuser cover and the diffuser, wherein the one or more decorative features comprise one or more interactive elements in electrical communication with the diffuser through the electrical interface. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the removable diffuser cover comprises the controller and the controller is in communication with the diffuser through the electrical interface to control the one or more operations of the diffuser. ### Claim 8 (depends on 6) The apparatus of claim 6, wherein the diffuser comprises the controller and the controller is in communication with the one or more interactive elements through the electrical interface to control the one or more interactive elements. ### Claim 9 (depends on 6) The apparatus of claim 6, wherein the one or more interactive elements comprise one or more of a light, a speaker, and a mechanical actuator of the removable diffuser cover. ### Claim 10 (depends on 6) The apparatus of claim 6, wherein the one or more openings of the removable diffuser cover comprise a plurality of openings and the one or more interactive elements comprise one or more valves that selectively direct the dispersed liquid through different openings of the plurality of openings of the removable diffuser cover. ### Claim 11 (depends on 5) The apparatus of claim 5, wherein the diffuser element comprises an ultrasonic plate and the controller is configured to calibrate the diffuser element by reading information from the diffuser element and adjusting a frequency of the ultrasonic plate. ### Claim 12 (depends on 4) The apparatus of claim 4, wherein the diffuser continues to provide the dispersed liquid in response to the removable diffuser cover being removed. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein the removable diffuser cover comprises one of a plurality of compatible covers for the diffuser, each of the plurality of compatible covers comprising one or more electrical interfaces, dispersed liquid interfaces, decorative features, or interactive elements. ### Claim 14 (depends on 1) The apparatus of claim 1, further comprising a coupling element allowing a user to release the removable diffuser cover from the diffuser. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the coupling element comprises a spring-loaded latch allowing the user to release the removable diffuser cover from the diffuser by hand, without using a tool. ### Claim 16 A system comprising: a plurality of removable diffuser covers each comprising one or more decorative features; a cavity open in a bottom surface of each of the plurality of removable diffuser covers shaped to receive a full height of a diffuser down to a base of the diffuser, the diffuser comprising a diffuser element that disperses a liquid into air within a diffuser chamber and a lid shaped to at least partially enclose an upper opening of the diffuser chamber, the lid comprising an inner surface sloping inward and upward away from a center of the diffuser chamber equally on all sides to form a single aperture disposed in a center of the lid such that the lid comprises a splash guard, the splash guard adapted to slow the liquid from spilling out of the diffuser chamber when the diffuser is tipped or overturned during use, wherein the splash guard includes a convex surface and the convex surface is positioned between the removable diffuser cover and the diffuser chamber such that the dispersed liquid flows between the convex surface of the splash guard and the inner surface of the lid to the single aperture of the lid; and one or more openings in each of the plurality of removable diffuser covers positioned to allow the dispersed liquid to pass from the lid of the diffuser to an exterior of each of the plurality of removable diffuser covers. ### Claim 17 (depends on 16) The system of claim 16, further comprising the diffuser, the one or more decorative features of the plurality of removable diffuser covers having different external shapes than the diffuser, the diffuser being compatible with each of the plurality of removable diffuser covers.
