Abstract

The invention relates to an air purification device comprising a casing ( 1 ) that houses a fan ( 2 ) and a filter ( 3 ) placed in front of said fan ( 2 ), such that air passes through said filter ( 3 ) and exits the casing ( 1 ) by means of said fan ( 2 ), and is characterised in that said filter ( 3 ) is placed in a replaceable part ( 4 ) mounted in a detachable way in said casing ( 1 ), said replaceable part ( 4 ) comprising material with volatile substances ( 5 ). It allows an air purification device to be provided which allows for the purification of air and the diffusion of volatile substances at the same time.

First claim

The invention claimed is:

1. An air purification device comprising a casing ( 1 ) that houses a fan ( 2 ) and a filter ( 3 ) placed in front of said fan ( 2 ), such that air passes through said filter ( 3 ) and exits the casing ( 1 ) by means of said fan ( 2 ), wherein in that said filter ( 3 ) is placed in a replaceable part ( 4 ) mounted in a detachable way in said casing ( 1 ), said replaceable part ( 4 ) comprising material with volatile substances ( 5 ), and
said casing ( 1 ) comprises an inlet ( 6 ) for providing volatile substances into said fan ( 2 ) and a chamber ( 7 ) for said volatile substances;
wherein the filter ( 3 ) and inlet ( 6 ) are provided in independent channels, wherein the filter ( 3 ) is positioned in a main axis of flow with the fan ( 2 ) to provide filtered air and the inlet ( 6 ) is provided in a secondary channel, independent of the main axis of flow, and in communication with the chamber ( 7 ) to provide volatile substance to be mixed with the filtered air.

2. The air purification device according to claim 1 , wherein said chamber ( 7 ) is placed around said fan ( 2 ).

3. The air purification device according to claim 1 , wherein said filter ( 3 ) is a filter with multiple layers that filters particles and gases.

4. The air purification device according to claim 1 , wherein said replaceable part ( 4 ) comprises a grill ( 8 ) for the entry of air.

5. The air purification device according to claim 1 , wherein said replaceable part ( 4 ) comprises a window ( 9 ) to be able to see the material with volatile substances ( 5 ) that remains in the replaceable part ( 4 ).

6. The air purification device according to claim 1 , wherein said casing ( 1 ) comprises a single push button ( 10 ) for turning on the device, turning off the device and selecting the operating mode.

7. The air purification device according to claim 1 , wherein said replaceable part ( 1 ) comprises an air purification percentage indicator ( 11 ).

8. The air purification device according to claim 1 , wherein said casing ( 1 ) comprises a replaceable part presence detector ( 4 ), wherein said detector prevents the device from turning on if it does not detect the presence of the replaceable part ( 4 ).

9. The air purification device according to claim 1 , wherein the inlet ( 6 ) for volatile substances into the fan ( 2 ) is independent from said filter ( 3 ).

10. The air purification device according to claim 1 , wherein said casing ( 1 ) comprises a chamber ( 7 ) for said volatile substances.

11. The air purification device according to claim 10 , wherein said chamber ( 7 ) is placed around said fan ( 2 ).
