## Abstract

Apparatuses, systems, methods, and computer program products are disclosed for a diffuser and interchangeable cover. A complete diffuser includes a diffuser element that disperses a liquid into air within a diffuser chamber of the complete diffuser. A complete diffuser includes a lid shaped to at least partially enclose an upper opening of a diffuser chamber. A cover is removably couplable to a complete diffuser over a diffuser lid so that a dispersed liquid passes through one or more openings in the cover. A cover includes one or more decorative features having a different external shape than a complete diffuser that receives the cover.

## Claims

### Claim 1

A system comprising: a diffuser comprising, a diffuser element, disposed in a bottom of a diffuser chamber, that disperses a liquid into air within the diffuser chamber of the diffuser; and a lid comprising an annular channel adjacent to an outer edge of the lid, the annular channel opening downward toward the diffuser chamber, the lid being shaped to at least partially enclose an upper opening of the diffuser chamber, the lid comprising an external opening, protruding through the lid, shaped to form a vertical diffuser stream with pressure from a forced air source; wherein the lid comprises a splash guard, the splash guard comprises a dome shape and is adapted to slow the liquid from spilling out of the diffuser chamber when the diffuser is tipped or overturned during use; and a cover removably couplable to the diffuser over the diffuser lid such that the dispersed liquid passes through one or more openings in the cover, the cover comprising one or more decorative features having a different external shape than the diffuser.

### Claim 2 (depends on 1)

The system of claim 1, further comprising a controller configured to control one or more operations of the diffuser.

### Claim 3 (depends on 2)

The system of claim 2, wherein the cover further comprises an electrical interface with the diffuser, and the one or more decorative features comprise an interactive element in electrical communication with the diffuser through the electrical interface.

### Claim 4 (depends on 3)

The system of claim 3, wherein the 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 5 (depends on 3)

The system of claim 3, wherein the diffuser comprises the controller and the controller is in communication with the interactive element through the electrical interface to control the interactive element.

### Claim 6 (depends on 3)

The system of claim 3, wherein the interactive element comprises one or more of a light, a speaker, and a mechanical actuator of the cover.

### Claim 7 (depends on 3)

The system of claim 3, wherein the interactive element comprises one or more valves that selectively direct the dispersed liquid through different openings of the one or more openings of the cover.

### Claim 8 (depends on 2)

The system of claim 2, 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 9 (depends on 1)

The system of claim 1, wherein the cover comprises one of a plurality of compatible covers, each of the compatible covers of the plurality of compatible covers comprising one or more electrical interfaces, dispersed liquid interfaces, and an interactive element different from an interactive element of at least one other compatible cover of the plurality of compatible covers.

### Claim 10 (depends on 1)

The system of claim 1, further comprising a coupling element allowing a user to release the cover from the diffuser.

### Claim 11 (depends on 10)

The system of claim 10, wherein the coupling element comprises a spring loaded latch allowing the user to release the cover from the diffuser by hand, without using a tool.

### Claim 12 (depends on 1)

The system of claim 1, wherein the diffuser continues to provide the dispersed liquid in response to the cover being removed.
