Patent ID: 8443836

Claim:
A ventilating apparatus having a configuration extending along a first axis, a second axis and a third axis, wherein the first axis, the second axis and the third axis are orthogonal to each other, the ventilating apparatus comprising: a main body made of porous ceramics having an outer surface, the main body further having a head end and a tail end disposed along the second axis, a first aperture passing therethrough along the first axis near the head end of the main body, and a first air orifice extending along the second axis, wherein the first air orifice passes through from the tail end of the main body to the first aperture; a tail pipe being connected to the tail end of the main body and having a second aperture passing therethrough along the second axis, wherein the second aperture is connected to the first air orifice; an airtight sealing material covering the outer surface of the main body with the first aperture exposed; and an outer pipe having a bottom segment and two side segments connected to two ends of the bottom segment so as to be formed as a U-shaped pipe that allows the main body to be fittingly received in an area defined by the U-shaped pipe with the head end of the main body adjacent to the bottom segment, the outer pipe further comprising bypassing channels and a plurality of air vents, the bypassing channels being configured inside the bottom segment and the side segments, and the air vents connecting the bypassing channels to an exterior of the outer pipe.
