Definitions

  • the invention relates to electric depilatory devices intended to be held in the hand.
  • the invention relates, more particularly, to a hair removal device comprising, in a housing intended to be held in the hand, a motor unit whose output shaft rotates a hair removal tool.
  • a hair removal device comprising, in a housing intended to be held in the hand, a motor unit whose output shaft rotates a hair removal tool.
  • the plucking tool often consists of a spring rotating on itself or of rotating metal blades. These devices have the disadvantage of being quite painful and sometimes not to pull the hair correctly but to break it on the surface of the skin.
  • the object of the invention is to remedy these drawbacks and in particular to produce a more efficient device, while being pleasant to use.
  • the housing has a head through which the shaft passes and comprising on its external face at least one cam extending axially
  • the depilation tool comprises, on the one hand, a cover driven in rotation by the motor shaft and having openings and, on the other hand, a plurality of tearing means arranged circumferentially and partially passing through the respective openings of the cover, each tearing means having axially directed teeth, arranged concentrically with the shaft and integral with an elastically deformable operating member, so that, during the rotation of the cover, each tear-off means can occupy practically two states, namely a tear-off state in which it is brought by pressing the cam on the operating member and for which the teeth are brought together against each other to grasp the bristles, that is to say a state of rest in which it is brought about by release of said operating member which regains its shape and for which the teeth are separated .
  • the hairs which are between the teeth are gripped at the moment when the teeth tighten, then are pulled out by the combined effect of the prolonged wedging and the rotational movement of the cover.
  • the teeth loosen the plucked hairs fall out on their own.
  • Hair removal is almost painless since the hairs are gripped as close as possible to the surface of the skin and therefore to their roots in the manner of forceps. Multiplying the number of teeth increases the number of hair taken, and therefore the effectiveness of hair removal.
  • the plucking means protruding slightly from the cover, perform, simultaneously with plucking the hairs, a massage of the skin which contributes to making depilation more pleasant.
  • Figure 1 shows a partial cross-sectional view of a hair removal device according to the invention
  • Figure 2 shows a bottom view on a smaller scale of the head of the device
  • Figure 3 shows on the same scale as in Figure 2 a bottom view of the lifting means of the device
  • Figure 4 also shows on the same scale as in Figure 2 a bottom view of the cover of the device.
  • the hair removal device shown in Figure 1 comprises, in a housing 1 (shown in broken lines) intended to be held in the hand, a motor unit 2 (shown in broken lines) whose output shaft 3 rotates a hair removal tool 4.
  • the housing 1 has a head 5 traversed by the shaft 3 and comprising on its external face 6 three cams 7 extending in height axially and in length according to a determined sector.
  • the head 5 is advantageously made of plastic and is mounted on the housing 1 by a removable fixing means, for example by screwing (not shown) the head 5 on the housing 1.
  • the hair removal tool 4 has a plastic cover 8 which is rotated by the shaft 3 of the motor 2 by means of a mutual coupling device, for example by interlocking complementary hexagonal shapes.
  • the cover 8 is mounted on the head 5 by elastic locking means, for example by means of elastic lugs 9 penetrating into a housing 10.
  • the cover 8 has six openings 11.
  • the hair removal tool 4 further comprises six tear-off means 12 arranged circumferentially and partially passing through the respective openings 11 of the cover 8.
  • the tear-off means are thus integral in rotation with the cover.
  • Each lifting means 12 comprises teeth 13 axially directed, arranged concentrically with the shaft 3 and integral with an operating member 14 of the teeth.
  • the operating means 14 and the teeth 13 are advantageously made in a single piece of plastic material such as for example homopolymer polyacetal, sold under the name DELRIN (brand of the Dupont de Nemours company).
  • Each operating member 14 has a foot in which a U-shaped groove 15 is formed, open in the direction of the cam 7 and of radial width less than that of the cam 7.
  • the groove 15 has lateral walls 16 extending in an arc concentric with the tree and a bottom 17, carrying the teeth, which is thinned. Said bottom of the groove 15 thus constitutes a sort of connecting hinge between the teeth and the side walls.
  • each tear-off means 12 can occupy practically two states, that is to say a tear-off state in which it is brought by pressing the cam 7 on the operating member 14 and for which the teeth 13 are brought together against each other to grip the bristles, that is to say a state of rest in which it is brought about by release of said operating member 14 which recovers its shape and for which the teeth 13 are separated.
  • each wall 16 pivoting around a horizontal pivot 18 located in the bottom 17 at the junction of the wall 16 and the bottom 17 , and transmitting in particular its pivoting movement to the corresponding external tooth (13 ').
  • Said pivot 18 is materially constituted by the connection between the thinned bottom and the assembly formed by the wall and the corresponding tooth.
  • a foot 14 engages on a cam 7 which is inserted between the side walls 16 of said foot 14 and which, due to the more large radial width of the cam, separates said walls 16 from one another.
  • This symmetrical support on the walls 16 causes the teeth 13 to come together against each other, by a pivoting effect of the two external teeth 13 'around the pivot 18.
  • the bristles which are between the teeth 13 are then pinched.
  • the rotational movement associated with the prolonged pinching then makes it possible to pluck the hairs.
  • the deformation could be asymmetrical, the cam then pressing only on a single wall.
  • the teeth 13 slightly protruding from the cover 8, perform a light massage of the skin to make hair removal more pleasant.
  • the tear-off means 12 are carried by a ring 19 concentric with the shaft 3 and each groove 15 of a foot 14 is equipped with a guide rib 20 arranged at center of the groove 15, concentrically with the shaft 3 and the crown 19 is arranged in the extension of the ribs 20.
  • the cams 7 are connected together by an annular skirt 21 extending axially, and have circumferentially a slot 22 whose bottom 23 is located at the same level as the free edge 24 of the skirt 21.
  • the rib 20 comes, on the one hand, to be introduced into the slot 22 when the stripping means 12 occupy their stripping state and, on the other hand, opposite the free edge 24 of the skirt 21 when the tearing means 12 occupy their rest state.
  • the crown 19 is supported on the internal face 25 of the cover 8 between the openings 11.
  • the crown 19 is held between the cover 8 and the skirt 21 of the head 5, preventing any unwanted axial movement for good lifting efficiency.
  • the head 5 being removable, the assembly produced by said head and the hair removal tool 4 can constitute an accessory which can be interchanged, for example, with a massage tool, for polishing the skin, etc. more, the head 5 and the hair removal tool 4 being entirely made of plastic, they are easy to clean because it can, for example, immerse the assembly in a disinfectant liquid such as alcohol.
