ABSTRACT:
A compact, small size humidifier which may be used as a portable humidifier. The humidifier may include the appropriate electrical plugs and internal electrical transformer to allow use in different countries with different voltages and electrical power systems, e.g., 110V use in the United States, 220V use in Europe, etc. The humidifier also includes an opening for receiving a number of different sockets allowing use of different sized water bottles as the water tank. The different sockets may be detachably affixed to the humidifier body in appropriate recesses or holding arrangements so that the different sockets are easily made available to the user. The humidifier may also include a low water detection assembly which utilizes, e.g., two projecting probes positioned in the water retaining chamber, to indicate the presence of a sufficient amount of water. Conversely, when the water drops below a certain, safe level, there is no longer an electrical signal indicated by one or both of the two probes, indicating that the water is below a certain threshold level. This indication is then used to shut off the humidifier to prevent damage to the unit, as well as any possible accident or injury.
