DETAILED DESCRIPTION OF THE INVENTION

[0051] Unlike the beard trimmers of the state of the art, the trimmer according to the present invention has one or several vertical axis circular rotary heads 1, surrounded by crown-shaped combs 4, the height of which can be adjusted to within half a millimeter relative to the fixed blade. This adjustment can be manual or motorized (not shown). This trimmer allows a movement in arcs of circle over the beard, just like a rotary head razor. This type of movement has the advantage of beginning to trim the beard hairs from all sides, irrespective of the incline thereof relative to the skin, which results in uniform trimming of the beard.

[0052] The movement of the combs 4 raises the hair, which ultimately penetrate from the outside of the combs toward the cutting system made up of a fixed blade 3 and a moving blade 2 via the space left between the teeth in the trimming zone. The particular shape of the teeth of the comb 4, which become gradually finer toward the tip, allows easy penetration of the beard hairs toward the cutting system.

[0053] The fixed blade 3 comprises radial notches, which also favors the penetration of the hairs in the cutting mechanism.

[0054] The height of the telescoping combs 4 can be adjusted approximately between 0 and 20 mm, preferably between 0 and 15 mm, and particularly preferably between 0 and 12 mm. The combs are therefore almost completely retractable in the cover 5 to take up less space when storing the trimmer.

[0055] The cleaning function of the trimmer according to the invention is very important inasmuch as a beard trim, which is often done only once or twice per week, generates significantly more cutting waste than simple shaving.

[0056] The present invention therefore proposes a series of solutions making it possible to facilitate and improve cleaning of the device, which include, among other things: [0057] an opening functionality of the trimmer making it possible to detach the cover 5 from the handle 18 and to open the device while keeping the cover 5 fastened thereon. The opening thus allows rinsing with water by passing water from the inside toward the outside or from the outside toward the inside (see FIGS. 5 and 6); [0058] a cylinder 9 with radial or helical fins is fastened on the rotation axis of the moving blade and makes it possible to generate a more intense flow of water through the cutting mechanism (see FIG. 7); [0059] a cleaning kit 13 comprising a base and a reservoir 14 suitable for receiving the trimmer according to the invention. In use, the trimmer is immersed in a cleaning liquid that may be set in motion by a helix 15.

[0060] The mechanism making it possible to open the trimmer according to the invention is shown in FIGS. 7 (closed position) and 8 (open position).

[0061] First, a manual or motorized arm 12 pushes the comb via a bearing part 16 to release the anchoring 10 and push the combs toward a maximum height position. The cover is next pushed upward via a spring surrounding a central shaft 11.

[0062] After rinsing with water, the cover 5 is pushed back into its starting position and the trimmer is closed.

[0063] The trimmer also comprises two backup push buttons 17 making it possible to remove the entire cover if the opening mechanism seizes up due to an excessive quantity of cut hairs in the cutting system.

[0064] After several hours of use, simple rinsing with water may no longer be sufficient to clean the trimmer. This is why a cleaning kit is provided for in-depth cleaning of the device. This cleaning kit comprises a reservoir with a detergent solution provided for the trimmer. It may also comprise a helix intended to stir the solution and/or an ultrasound generator. The trimmer according to the invention can be submerged therein after the cover 5 has been completely removed from the device. Lastly, the cleaning kit can also, in addition to the cleaning and ultrasound functions, comprise a charging function for the battery of the trimmer according to the invention. The cleaning kit can thus combine the charging and ultrasonic bath functions. The connecting means 19 between the trimmer and the cleaning kit make it possible to provide the pulses necessary for the cleaning cycle shown in FIG. 12.
