The present patent incorporates major improvements and simplifications of 1976 U.S. Pat. No. 3,967,449 necessary to make the concept functional and useful on a large scale. The earlier patent listed many approaches to the several design problems believed to be necessary at the time of the earlier application, while this one reflects the extensive research and laboratory investigation to identify, validate and demonstrate the functionality of the various parts. In particular, the methods for producing the necessary nuclei for steam bubble production, the method of insuring bubble growth, the method of condensing the steam bubbles produced and methods for minimizing the release of air in large bubbles, and for dealing with those that are released are covered in detail. The first patent, with 50 claims listed many approaches to many problems, some of which were either misunderstood from an unsatisfactory literature or unnecessarily complicated. To an extent those have been eliminated, resulting in what appears to be the simplest embodiment of the concept.

A drain fitting comprising a cage having a plurality of apertures extending through the cage; a conduit having an inlet and an outlet, the conduit extending at least partially through the cage; and a base cap attached to the cage, the outlet located within the base cap wherein the conduit includes an internal surface that extends from the inlet to the outlet, the internal surface increasing the velocity of the water substantially the length of the internal surface as the water passes from the inlet to the outlet.

The invention relates to a fruit and vegetable cleaning machine. The fruit and vegetable cleaning machine comprises a machine body, a washing barrel for containing water, an upper cover and a washing basket for containing fruits and vegetables, wherein a washing rotating shaft is arranged in the washing barrel; the washing basket is arranged on the washing rotating shaft; the fruit and vegetable cleaning machine also comprises an ozone generator, an aerating apparatus and an aerating rotating shaft, and the aerating apparatus and the aerating rotating shaft are arranged on the washing barrel; the aerating apparatus is arranged on the aerating rotating shaft; an air inlet hole communicated with the ozone generator is formed on the washing barrel; a driving device for driving the washing rotating shaft and the aerating rotating shaft to rotate is arranged in the machine body; the aerating apparatus comprises a suction port and an aerating piece; ozone generated by the ozone generator enters the washing barrel through the air inlet hole to form ozone bubbles; and the ozone bubbles are aerated by the aerating apparatus to be broken up, micro-fined down and rapidly dissolved in water. Therefore, the drawback of the traditional aeration stone is avoided, the concentration of the ozone dissolved in and entering water is ensured to the maximum extent, the purification effect of fruits and vegetables is ensured, the utilization rate of the ozone is increased while the dissolving efficiency of the ozone is increased through repeated aeration, and energy sources are saved.
