Abstract

A hair cutting system ( 100 ) is provided, the system comprising a hair cutting appliance ( 120 ) comprising one or more pairs of cutting blades ( 124 ) for cutting hair a comb ( 140 ) arranged forwards of the cutting blades and configured to guide hair towards the cutting blades; and a hair collector ( 160 ), the hair collector comprising a hair chamber ( 168 ) for receiving hair cut by the hair cutting appliance and a coupling portion ( 170 ) configured to couple the hair collector to the hair cutting appliance. A hair collector for the hair cutting system is also provided.

Claims (21)

1. A hair cutting system comprising:

a hair cutting appliance comprising one or more pairs of cutting blades for cutting hair;

a comb arranged forwards of the cutting blades and configured to guide hair towards the cutting blades;

a hair collector, the hair collector comprising a hair chamber for receiving hairs cut by the hair cutting appliance and a coupling portion configured to couple the hair collector to the hair cutting appliance;

wherein the hair chamber is defined by a base wall positioned adjacent to a body of the hair cutting appliance, a front wall opposite the base wall, and two or more side walls between the base wall and the front wall;

wherein, when the hair cutting system is assembled, a portion of the comb protrudes into the hair chamber;

wherein the portion of the comb protruding into the hair chamber comprises a plurality of comb teeth, and wherein the front wall at least partially extends over and forwards of the plurality of comb teeth in a cutting direction when the hair cutting system is assembled and used to cut hair;

wherein, the hair collector is capable of being coupled to the hair cutting appliance via the coupling portion when the comb is removed; and

wherein the comb is movable relative to the cutting blades to vary the length of hair cut by the hair cutting system such that the hair chamber remains in a same position relative to the one or more pairs of cutting blades as the comb is moved relative to the cutting blades.

2. The hair cutting system of claim 1 , wherein a wall of the hair chamber comprises an aperture, wherein a distal end of the comb extends into or through the aperture.

3. The hair cutting system of claim 1 , wherein an opening of the hair chamber for receiving hair is substantially closed by the cutting blades and the comb.

4. The hair cutting system of claim 1 , wherein a spacing between the comb teeth is between 1 mm and 6.8 mm, in order to restrict hairs from passing out of the hair chamber between the teeth of the comb.

5. The hair cutting system of claim 1 , wherein the base wall is configured to engage a surface of the body of the hair cutting appliance when the hair collector is coupled to the hair cutting appliance, wherein a free edge of the base wall at least partially defines an opening of the hair chamber.

6. The hair cutting system of claim 5 , wherein the hair cutting appliance comprises a recess configured to receive at least a portion of the base wall of the hair collector.

7. The hair cutting system of claim 5 , wherein an inside surface of the base wall is oriented substantially perpendicularly to a hair cutting plane of the hair cutting appliance at the free edge, and is substantially aligned with the surface of the body of the hair cutting appliance at a position away from the free edge.

8. The hair cutting system according to claim 5 , wherein the free edge of the base wall is substantially aligned with a distal end of the body of the hair cutting appliance.

9. The hair cutting system of claim 1 , wherein the base wall comprises a curved wall portion, wherein the orientation of the base wall transitions over the curved wall portion from being substantially perpendicular to a hair cutting plane at the free edge, to being substantially aligned with the surface of the hair cutting appliance body away from the free edge.

10. The hair cutting system of claim 5 , wherein the base wall comprises a ramped portion extended from the free edge, the ramped portion defining a hair flow surface substantially perpendicular to a hair cutting plane of cutting blades.

11. The hair cutting system of claim 1 , wherein the comb and hair collector are configured such that a clearance between a distal end of the comb and an inside surface of the hair chamber is substantially constant as the comb moves.

12. The hair cutting system of claim 1 , wherein the hair collector further comprises a hair retaining wall between a closed end of the hair chamber and an opening of the hair chamber.

13. The hair cutting system of claim 12 , wherein the hair retaining wall extends away from the base wall in a direction substantially perpendicular to the hair cutting plane of the cutting blades.
