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.

Abstract
Embodiments of present disclosure relates to a shaving assembly and a hair cutting appliance including the shaving assembly. The 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.
Description
- 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.
- In a construction, 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.
- In an alternative construction as disclosed in
CN106346519A , 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. However, 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. - In order to solve the discomfort and even safety issues caused by the sharp glide sides, embodiments of the present disclosure provide a shaving assembly with a protection element and a hair cutting appliance including the shaving assembly.
- In first aspect, a shaving assembly is provided. The 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.
- According to embodiments of the present disclosure, the protection element can effectively avoid a direct contact of the user's skin with the non-proceeded sharp edges, thereby enabling a skin-friendly contact with the user's skin.
- In some embodiments, the protection element and the end of the guard foil are integrally formed. In some embodiments, 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.
- In this design, the rounded surface does not change the overall flat shape of the contact surface and only locally changes the profile of the edges in the thickness direction. Therefore, the overall stiffness of the guard foil can be well maintained. Moreover, no additional element (or part) as well as the simple fabrication make such protection element cost-effective.
- In some embodiments, 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.
- In this design, such curved portion with a receding edge is allowed to be curved or bent in a large space. Therefore, the curvature of the curved portion can be largely adjusted. Thereby enabling high design flexibility.
- In some embodiments, 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.
- In this design, no additional element or part is required, which makes the protection element cost-effective. Moreover, the slight raising of the receding edge creates a small 'bulge', which can help in balancing the bending stress from the side for the main functional bend for the guard teeth. Meanwhile, such a small bulge has little to no effect on shaving performance.
- In some embodiments, 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.
- In some embodiments, 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.
- In this way, the original design of the guard foil will be not affected, which eases the fabrication of the guard foil. Moreover, such modular components-based shaving assembly allows manufacturers to individually fabricate all necessary components and store them for a future assembly. In addition, 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.
- In some embodiments, 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.
- In second aspect, a hair cutting appliance is provided. The 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.
- Through the following discussions, it would be apparent that compared to conventional hair cutting appliance, the hair cutting appliance including the skin-friendly shaving assembly according to various embodiments of present disclosure avoids a direct contact of the sharp edge to the user's skin, and thereby the discomfort and safety issue can be eliminated. Meanwhile, due to the less-expensive components and less-complex rounding design, the overall cost of the appliance is reduced and the fabrication/assembly is simplified.
- Drawings described herein are provided to further explain the present disclosure and constitute a part of the present disclosure. The example embodiments of the disclosure and the explanation thereof are used to explain the present disclosure, rather than to limit the present disclosure improperly.

FIG. 1A illustrates a perspective view of aconventional shaving assembly 100 in an unassembled status. As shown, the shavingassembly 100 generally includes a supportingmember 1, a cuttingelement 2 extending in a first direction X, and aguard foil 3 also extending in the first direction X. - The
contact surface 31 includes a plurality of guard teeth 37 (also referred to as "hair-catching cut-outs") arranged along the first direction X, and the cuttingelement 2 includes a plurality of movingteeth 21 arranged along the first direction X. In operation, under the control of a driving mechanism (is not shown), the movingteeth 21 are adapted to move (or oscillate) with respect to the plurality ofguard teeth 37 along the first direction X. For sake of discussion, the first direction X may be considered as a longitudinal direction of the shavingassembly 100. -
FIG. 1B illustrates a perspective view of the shavingassembly 100 in an assembled status. As shown, theguard foil 3 is stretched and surrounding the cuttingelement 2 via a bend of a part of theguard foil 3 with respect to an axis along the first direction X. In some embodiments, the thickness of theguard foil 3 is in a range of 40 to 120 micrometers, for example, 80 micrometers. - The
guard foil 3 includes abent part 38 and aflat contact surface 31. Thebent part 38 extends in the first direction X for fixing theguard foil 3 on the supportingmember 1. Theflat contact surface 31 is adapted to be in contact with skin of a user. - In addition to the two lateral sides along the first direction X, as further illustrated in
FIG. 1B , theflat contact surface 31 also includes twoglide 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 twoglide edges 39 are usually sharp and not optimal for shaving comfort or safety. - In view of the forgoing, according to various embodiments of the present disclosure, the shaving
assembly 100 as shown inFIGs. 1A-1B is further equipped with a skin-friendly protection element 4. Theprotection element 4 is arranged at theends 310 of theguard foil 3 and includes acurved 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. - Various embodiments of the shaving
assembly 100 with theprotection element 4 are described below with reference toFIGs. 2A-6C . - In some embodiments, the
protection element 4 and theends 310 of theguard foil 3 can be integrally formed. In other words, theprotection element 4 may be considered as a part of the guard foil. In an example embodiment, as shown inFIGs. 2A-2B , theprotection element 4 may include arounded surface 32 that is transiting from thecontact surface 31 of theguard foil 3 to abottom surface 33 of theguard foil 3.FIG. 2B shows a cross-sectional view of theprotection element 4 along the first direction X. As shown, therounded surface 32 may have a rounding radius R that is larger than or equal to a thickness T of theguard 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 thecontact surface 31 and only locally changes the profile of the edge in the thickness direction, or in other words, thebottom surface 33 of theguard foil 3 is kept substantially flat. Therefore, the overall stiffness of theguard 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. - Alternatively, in another example embodiment as shown in
FIG. 3 , theprotection element 4 includes acurved portion 34 transiting from theguard foil 3 and constructed to be gradually curved in a direction away from the skin Y1. In this design, thecurved portion 34 includes a firstcurved surface 341 transiting from thecontact surface 31 of theguard foil 3 and a secondcurved surface 342 transiting from abottom surface 33 of theguard foil 3. - In some embodiments, the
curved portion 34 may have a uniform thickness T1 that is substantially equal to the thickness T of theguard foil 3. In some other embodiments, variation in thickness throughout thecurved portion 34 may be allowed. - Because such
curved portion 34 with a receding edge is allowed to be curved or bent in a large space, the curvature of thecurved portion 34 can be largely adjusted. Thereby enabling high design flexibility. - In yet another example embodiment, the
protection element 4 may include a firstcurved portion 35 and a secondcurved portion 36, and which jointly define thecurved surface 41. For example, as shown inFIGs. 4A-4B , the firstcurved portion 35 is transiting from theguard foil 3 and constructed to be gradually curved in a direction towards the skin Y2, and the secondcurved portion 36 is transiting from the firstcurved portion 35 and constructed to be gradually curved in a direction away from the skin Y1. - In some embodiments, the first
curved portion 35 and the secondcurved portion 36 may have a uniform thickness T2 that is substantially equal to a thickness T of theguard foil 3. In some other embodiments, variation in thickness throughout the firstcurved portion 35 and secondcurved portion 36 may be allowed - In this design, no additional element or part is required, which makes the protection element cost-effective. Moreover, compared to the receding edge as shown in
FIG. 3 , the slight raising of the receding edge creates a small 'bulge', which can help in balancing the bending stress from the side for the main functional bend for theguard teeth 37. Meanwhile, such a small bulge has little to no effect on shaving performance. - In some embodiment as shown
FIGs. 5A-5B , theprotection element 4 can be constructed as a bead made of lacquer or resin and having a roundedprofile 47 surrounding theend 310 of theguard foil 3.Such protection element 4 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 shavingassembly 100 can be achieved due to the additional protection bead. - In some embodiment as shown
FIGs. 6A-6C , theprotection element 4 is constructed as asidewall 42 of the supportingmember 1. Thesidewall 42 includes thecurved surface 41 projecting beyond thecontact surface 31 in a second direction Y that is substantially perpendicular to the first direction X. It is to be appreciated that theside wall 42 may be integrally formed with the supportingmember 1. Of course, theside wall 42 may also be a separate component that is detachable from the supportingmember 1. In some embodiments, thesidewall 42 may surround theend 310 of theguard foil 3 to completely protect theend 310 of theguard foil 3 from being exposed to the user's skin. - In this way, the original design of the
guard foil 3 is not affected, which eases the fabrication of theguard foil 3. Moreover, such modular components-basedshaving assembly 100 allows manufacturers to individually fabricate all necessary components and store them for a future assembly. In addition, thesidewall 42 may also function as the side cover of the shavingassembly 100 to close the internal space defined by the supportingelement 1 and theguard 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. - It is to be understood that the above detailed embodiments of the present disclosure are only to exemplify or explain principles of the present disclosure and not to limit the present disclosure. Therefore, any modifications, equivalent alternatives and improvement, etc. without departing from the spirit and scope of the present disclosure shall be included in the scope of protection of the present disclosure.
