Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A humidifier, comprising: a first chamber means for storing water; a second chamber means in communication with said first chamber means for receiving water therefrom; means for atomizing water supplied from said first chamber means to said second chamber means; a cylinder, provided on an upper wall of said second chamber means, said cylinder providing communication between said second chamber and the atmosphere, the upper portion of the said cylinder having a step-like configuration comprising at least one horizontal wall and at least one vertical wall; a cap, having a side wall and an opening for discharging atomized water into the atmosphere, said cap being rotatably and detachably secured in the step-portion of said cylinder so as to form a groove between said side wall of said cap and said step portion for inhibiting capillary action of water produced at an interface between said cap and cylinder; and an eave extending from an upper end of said side wall of said cap for covering said groove.
Claim 2
Dependent Claim
