Abstract
Official abstract text for this publication.
A filter for a vacuum cleaner includes a top having an open center, a bottom plate having an outermost edge, a center, an inside surface facing towards the top, an outside surface facing away from the top, and a catch extending from the inside surface annularly around the center, filter material being secured between the top and bottom plate. An adaptor for a filter cage or the filter cage itself includes a radial retention ring that engages the catch of the filter.
First claim
Opening claim text (preview).
What is claimed is: 1. A vacuum cleaner, the vacuum cleaner comprising: a tank including a dirty air inlet; a motor housing comprising a motor, a filter cage having an end, and a clean air outlet; and a radial retention ring connected to the end of the filter cage, the end of the filter cage including round surface having an outer circumference and an inner circumference, the radial retention ring extending from the inner circumference of the round surface. 2. The vacuum cleaner of claim 1 , further comprising a filter surrounding the filter cage, the filter having a bottom plate with a catch that engages the radial retention ring. 3. The vacuum cleaner of claim 2 , wherein a mating face of the catch engages a mating end of the radial retention ring. 4. The vacuum cleaner of claim 3 , wherein the catch has an inclined end; wherein the radial retention ring has a sliding surface; and wherein, prior to engagement of the catch with the radial retention ring, the catch flexes via contact between the inclined end of the catch and the sliding surface of the radial retention ring. 5. The vacuum cleaner of claim 1 , wherein the radial retention ring is integral with the end of the filter cage. 6. A vacuum cleaner, the vacuum cleaner comprising: a tank including a dirty air inlet; a motor housing comprising a motor, a filter cage having an end, and a clean air outlet; and a radial retention ring provided on an adapter connected to the end of the filter cage, the adapter including an annular surface having an outer circumference and an inner circumference, the radial retention ring extending from the inner circumference. 7. The vacuum cleaner of claim 6 , further comprising a filter surrounding the filter cage, the filter having a bottom plate with a catch that engages the radial retention ring. 8. The vacuum cleaner of claim 7 , wherein a mating face of the catch engages a mating end of the radial retention ring. 9. The vacuum cleaner of claim 8 , wherein the catch has an inclined end; wherein the radial retention ring has an sliding surface; and wherein, prior to engagement of the catch with the radial retention ring, the catch flexes via contact between the inclined end of the catch and the sliding surface of the radial retention ring.
