Definitions

  • Embodiments of present disclosure generally relate to home appliance, and more specifically, to a shaving assembly and a hair cutting appliance including the shaving assembly.
  • Conventional trimmers or clippers for shaving and grooming facial hairs are designed to cut the hairs at a certain distance from the skin. Close shaving trimmers use a modified construction to enable hair cutting at a much closer distance from the skin than conventional trimmers. Normally, close shaving trimmers relies on thinner guard-teeth. Further, for achieving an effective and comfortable trim, complex rounding features and other features may also be needed.
  • the first skin-contacting portion of the teeth may be constructed, for example, from a moldable material (such as, plastic) combined with the thin metal guard teeth to enable the close hair cutting.
  • a moldable material such as, plastic
  • a thin and flat metal sheet with guard teeth or hair-catching cut-outs is stretched over a molded base.
  • This type of construction has an advantage in terms of cost, as it can be simply constructed from a flat sheet of thin foil.
  • this construction does not address the comfort and safety issue at the sides gliding over the skin.
  • the edges of both glide sides are straight and not optimal for shaving comfort or safety, as they are formed from a thin flat sheet by punching or cutting. In this case, uncomfortableness would be caused when the sharp glide slides are applied and glided on the skin.
  • embodiments of the present disclosure provide a shaving assembly with a protection element and a hair cutting appliance including the shaving assembly.
  • a shaving assembly comprises: a supporting member; a cutting element extending in the first direction; a guard foil stretched and extending in the first direction and surrounding the cutting element, the guard foil including a bent part and a flat contact surface, wherein the bent part extends in the first direction for fixing the guard foil on the supporting member, and the flat contact surface is adapted to be in contact with skin; and a protection element arranged at at least one end of the guard foil and including a curved surface exposed to the skin.
  • the protection element and the end of the guard foil are integrally formed.
  • the protection element includes a rounded surface transiting from the contact surface of the guard foil to a bottom surface of the guard foil, wherein the rounded surface has a rounding radius larger than or equal to a thickness of the guard foil.
  • the protection element includes a curved portion transiting from the guard foil and constructed to be gradually curved in a direction away from the skin, wherein the curved portion includes a first curved surface transiting from the contact surface of the guard foil and a second curved surface transiting from a bottom surface of the guard foil.
  • the protection element includes: a first curved portion transiting from the guard foil and constructed to be gradually curved in a direction towards the skin; and a second curved portion transiting from the first curved portion and constructed to be gradually curved in a direction away from the skin, wherein the first curved portion and the second curved portion jointly define the curved surface.
  • the protection element is constructed as a bead made of lacquer or resin and having a rounded profile surrounding the end of the guard foil.
  • Such protection element formed by for example a simple dipping or edge-painting of the sharp edge can provide an effective and low-cost protection solution. Moreover, a sufficient durability for the shaving lifetime of the shaving assembly can be achieved.
  • the protection element is constructed as a sidewall of the supporting member, wherein the sidewall includes the curved surface projecting beyond the contact surface in a second direction that is substantially perpendicular to the first direction. In some embodiments, the sidewall surrounds the end of the guard foil.
  • the sidewall may also function as the side cover of the shaving assembly to close the internal space defined by the supporting element and the guard foil during the hair cutting, so that the cut-off hair may be at least temporarily kept within the internal space without going to the ambient.
  • the contact surface includes a plurality of guard teeth arranged along the first direction; and the cutting element includes a plurality of moving teeth arranged along the first direction and adapted to move with respect to the plurality of guard teeth along the first direction.
  • a hair cutting appliance comprises: a shaving assembly according to the first aspect of the present disclosure; and a driving mechanism configured to cause a movement of the cutting element inside the shaving assembly.
  • FIG. 1A illustrates a perspective view of a conventional shaving assembly 100 in an unassembled status.
  • the shaving assembly 100 generally includes a supporting member 1, a cutting element 2 extending in a first direction X, and a guard foil 3 also extending in the first direction X.
  • FIG. 1B illustrates a perspective view of the shaving assembly 100 in an assembled status.
  • the guard foil 3 is stretched and surrounding the cutting element 2 via a bend of a part of the guard foil 3 with respect to an axis along the first direction X.
  • the thickness of the guard foil 3 is in a range of 40 to 120 micrometers, for example, 80 micrometers.
  • the flat contact surface 31 also includes two glide edges 39 which are oriented substantially perpendicular to the first direction X and exposed to the user's skin with no protection means provided thereon. As discussed above, in view of the fact that the glide edges 39 are formed by punching or cutting from a thin metal foil, these two glide edges 39 are usually sharp and not optimal for shaving comfort or safety.
  • the shaving assembly 100 as shown in FIGs. 1A-1B is further equipped with a skin-friendly protection element 4.
  • the protection element 4 is arranged at the ends 310 of the guard foil 3 and includes a curved surface 41 exposed to the skin of the user. In this way, a direct contact of sharp edges with the skin of the user can be avoided, thereby improving the shaving comfort and guaranteeing the shaving safety.
  • FIGs. 2A-6C Various embodiments of the shaving assembly 100 with the protection element 4 are described below with reference to FIGs. 2A-6C .
  • the protection element 4 and the ends 310 of the guard foil 3 can be integrally formed. In other words, the protection element 4 may be considered as a part of the guard foil.
  • the protection element 4 may include a rounded surface 32 that is transiting from the contact surface 31 of the guard foil 3 to a bottom surface 33 of the guard foil 3.
  • FIG. 2B shows a cross-sectional view of the protection element 4 along the first direction X. As shown, the rounded surface 32 may have a rounding radius R that is larger than or equal to a thickness T of the guard foil 3.
  • Such an arced edge with a radius approaching the thickness of the guard foil 3 (may also referred to as "a radiused edge”) can be achieved, for example, by polishing the edges of the contact surface 31.
  • the radiused edge does not change the overall flat shape of the contact surface 31 and only locally changes the profile of the edge in the thickness direction, or in other words, the bottom surface 33 of the guard foil 3 is kept substantially flat. Therefore, the overall stiffness of the guard foil 3 can be well maintained. Moreover, no additional element or part, as well as the simple polishing proceeding, make the protection element cost-effective.
  • the protection element 4 includes a curved portion 34 transiting from the guard foil 3 and constructed to be gradually curved in a direction away from the skin Y1.
  • the curved portion 34 includes a first curved surface 34 1 transiting from the contact surface 31 of the guard foil 3 and a second curved surface 34 2 transiting from a bottom surface 33 of the guard foil 3.
  • the protection element 4 may include a first curved portion 35 and a second curved portion 36, and which jointly define the curved surface 41.
  • the first curved portion 35 is transiting from the guard foil 3 and constructed to be gradually curved in a direction towards the skin Y2
  • the second curved portion 36 is transiting from the first curved portion 35 and constructed to be gradually curved in a direction away from the skin Y1.
  • first curved portion 35 and the second curved portion 36 may have a uniform thickness T2 that is substantially equal to a thickness T of the guard foil 3. In some other embodiments, variation in thickness throughout the first curved portion 35 and second curved portion 36 may be allowed
  • the protection element 4 is constructed as a sidewall 42 of the supporting member 1.
  • the sidewall 42 includes the curved surface 41 projecting beyond the contact surface 31 in a second direction Y that is substantially perpendicular to the first direction X.
  • the side wall 42 may be integrally formed with the supporting member 1.
  • the side wall 42 may also be a separate component that is detachable from the supporting member 1.
  • the sidewall 42 may surround the end 310 of the guard foil 3 to completely protect the end 310 of the guard foil 3 from being exposed to the user's skin.
  • the original design of the guard foil 3 is not affected, which eases the fabrication of the guard foil 3.
  • such modular components-based shaving assembly 100 allows manufacturers to individually fabricate all necessary components and store them for a future assembly.
  • the sidewall 42 may also function as the side cover of the shaving assembly 100 to close the internal space defined by the supporting element 1 and the guard foil 3 during the hair cutting. In this way, the cut-off hair may be at least temporarily kept within the internal space without going to the ambient.
