Inertion funnel
An inertion funnel includes a hollow ring with an attachment point on an outside edge and a plurality of output apertures on the inside edge allows for an even flow of gas around the circumference of the ring and through the output apertures into a filter funnel below. The attachment point allows the attachment of a hose or other fitting through which gas flows into the hollow ring, which rests above and around the opening of the filter funnel. On the inside of the ring, an angled downward opening allows gas to flow out of the ring and into the filter funnel. Uniformly distributed around the opening are vanes that direct the flow of gas from the ring into the filter funnel below.
1. An inertion funnel comprising:
a hollow ring having an outer wall and an inner wall, the inner wall having a top end and a bottom end, the top end having a larger diameter than the bottom end and the wall sloping from the top end to the bottom end to create an inner opening, the bottom end forming a downward opening structured to allow a flow of gas around a circumference of the hollow ring and through the downward opening;
a connection point having a cylindrical wall with a first end and a second end, the first end of the cylindrical wall having an opening on the outer wall and the second end of the cylindrical wall having an opening structured to receive a hose input, the connection point structured to allow introduction of gas through the hose input into a cavity formed between the inner wall and the outer wall; and
a plurality of output apertures to the cavity formed between the inner wall and the outer wall and distributed around the inner wall of the hollow ring, the output apertures structured to direct the flow of gas from the inner wall of the hollow ring to a vessel below the downward opening of the inertion funnel.
2. The inertion funnel of claim 1 , further comprising a notch around a circumference of the bottom end of the hollow ring.
3. The inertion funnel of claim 1 , wherein the connection point includes a screw thread having a plurality of turns on an interior wall of the connection point.
4. The inertion funnel of claim 1 , wherein the inertion funnel is comprised of nylon, acrylonitrile butadiene styrene plastic, thermoplastic polymer, or other rigid material.
5. The inertion funnel of claim 1 , wherein the inertion funnel is a unibody construction.
6. The inertion funnel of claim 1 , wherein a height of the inertion funnel is approximately 20-100 millimeters.
7. The inertion funnel of claim 1 , wherein a diameter of the bottom end of the inner wall of the hollow ring is approximately 10-120 millimeters and a diameter of the outer wall of the hollow ring is approximately 40-150 millimeters.
8. The inertion funnel of claim 1 , wherein the inertion funnel includes approximately ten output apertures.
9. The inertion funnel of claim 1 , wherein the downward opening is angled downward at approximately 45 degrees.
10. The inertion funnel of claim 1 , wherein the output apertures are approximately 4-20 millimeters long.
11. The inertion funnel of claim 1 , wherein the output apertures are approximately 1-10 millimeters wide.
12. The inertion funnel of claim 1 , wherein a top surface of the hollow ring is angled downward at approximately 45 degrees.
