## Abstract

A convertible humidifier that includes a base portion that produces mist, a control panel that controls the production of the mist by the base portion, a reservoir, detachably connectable to the base portion, which holds water to be used by the base portion to produce the mist, and a nozzle configured to direct the mist. The reservoir includes a pass-through connection that allows the mist produced by the base portion to be directed to an opening on a top surface of the reservoir. The nozzle is detachably connected to the opening on the top surface in a first operation mode, and the nozzle is detachably connected to an extending portion, which is detachably connected to the opening on the top surface, in a second operation mode.

## Claims

### Claim 1

A humidifier, comprising:
a base portion including an ultrasonic mist generator;
a fluid reservoir configured to hold fluid to be used by the ultrasonic mist generator, the fluid reservoir including a top surface and a bottom surface, wherein the top surface comprises an opening and wherein said bottom surface comprises a tank cap and a pass-through connection, said fluid reservoir being removably connected to said base portion such that fluid in the reservoir can be delivered to the base through the tank cap where the fluid can be converted to a mist by the ultrasonic mist generator and then delivered through the pass-through connection toward the opening on the top surface of the reservoir;
a movable nozzle for disbursing the mist; and
an elongated tube comprising a first end and a second end;
wherein the humidifier is configured to operate in a first or a second operation mode;
wherein in the first operation mode, the nozzle is directly connected to the opening in the top surface in the reservoir and the elongated tube is not attached to the humidifier; and
in the second operation mode, the first end of the elongated nozzle is directly attached to the opening in the top surface of the reservoir while the nozzle is connected to the second end of the elongated tube such that the elongated tube extends above the top end of the reservoir, wherein the same nozzle is used in the first and second operation modes.

### Claim 2 (depends on 1)

The humidifier as recited in claim 1, further comprising a processor for controlling the operation of the humidifier.

### Claim 3 (depends on 2)

The humidifier as recited in claim 2, wherein the processor is configured to control the output level of mist produced by the humidifier.

### Claim 4 (depends on 2)

The humidifier as recited in claim 2, wherein the processor is configured for monitoring ambient humidity outside the humidifier to selectively adjust the operation for the humidifier to achieve desired humidity levels outside the humidifier.

### Claim 5 (depends on 1)

The humidifier as recited in claim 1, wherein the nozzle has at least two openings for directing mist from said elongated tube.

### Claim 6 (depends on 5)

The humidifier as recited in claim 5, wherein the at least two openings are each selectively and independently rotatable around a longitudinal axis of the nozzle.
