Abstract
The lever operating mechanism for air-pressure utilizing hot pots referred to in the present invention that have a simple construction of lever operating mechanism, is able to raise and collapse the lever and maintain the lever raised and collapsed condition extremely easily and smoothly, and achieves superb operability and satisfactory discharge because all the operations can be carried out simply by moving the free end of the operating lever up and down with only one finger. The lever operating mechanism of the air-pressure utilizing hot pot referred to in the present invention comprises a compression process in which the free end of the operating lever is raised from the operating lever contained condition, and the operating lever, arm, and inside lever are engaged and operated in linkage to bring the bellows pump into the compressible condition, an operating lever downwards movement process in which the operating lever is operated to move downwards and the bellows pump is pressed down during this compression process, an operating lever return process for returning the operating lever, a lever sliding process where the free end of the operating lever of this operating lever retu…
