Description

Technical Field

[0001] The present invention relates to the technical field of razors, and in particular to a blade net, a method for preparing the blade net, and a razor. Background Art

[0002] An electric shaver is a cosmetic appliance that uses electricity to drive blades to shave beards and sideburns. An electric shaver consists of a stainless steel foil, inner blades, a micro motor, and a housing. The foil, or fixed outer blades, has numerous holes through which beard hairs can be inserted. The electric motor, powered by electricity, drives the inner blades, which, using a shearing principle, cut the hairs that enter the holes. Traditional shavers have thin outer blades with several circular or other shaped holes. While the small holes make it easy to insert short hairs, they can be difficult to insert into curly or long beards. This often requires trimming long hairs before shaving, or trimming any remaining hairs after shaving. Consequently, these shavers have a drawback of being difficult to remove long hairs, making it difficult to shave both long and short hairs in one go.

[0003] Later, someone developed a razor with two or three symmetrically spaced circular blades, each with slots. Because the slots facilitated the insertion of long hair, this razor could shave both long and short beards in one go. However, because the blades were positioned at two or three points, they couldn't simultaneously reach the face, resulting in a small shaving area. Furthermore, the razor required constant movement and angle adjustment to expand the shaving area, making it cumbersome to use. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a blade net, a method for preparing the blade net and a razor. The blade net has a simple structure, a large shaving area, high strength and is not easy to deform. It can also achieve the purpose of shaving long or curly beards in one go.

[0005] A knife net comprises: a first support plate, the first support plate is enclosed, and a through hole is formed on the inner side of the first support plate; a second support plate, the second support plate is located on the outer side of the first support plate, the second support plate is arranged opposite to the first support plate, the second support plate is arranged along the circumference of the first support plate, a groove is formed between the second support plate and the first support plate, and both sides of the groove are open; a shaving plate, one side of the shaving plate is connected to the first support plate, and the other side of the shaving plate is connected to the second support plate, the shaving plate covers one side of the groove, and a plurality of beard entry holes are provided on the shaving plate, and the plurality of beard entry holes are arranged along the shaving plate.

[0006] The present application discloses a blade net that facilitates the assembly of external blades by forming a groove between a first support plate and a second support plate. Furthermore, connecting the first support plate and the second support plate via a shaving plate facilitates support of the shaving plate, thereby preventing collapse of the shaving plate due to lack of support. The coordination of the first support plate, the second support plate, and the shaving plate effectively expands the shaving surface, while also providing good support for the shaving plate to prevent deformation and enhance the user experience. To expand the shaving surface, simply enlarge the area of ​​the through-hole in the first support plate and the gap between the first and second support plates, effectively enhancing the user experience.

[0007] In one embodiment, the shaving plate includes a plurality of shaving ribs, one side of the plurality of shaving ribs is connected to the first support plate, and the other side is connected to the second support plate. The plurality of shaving ribs are arranged in sequence along the notch of the groove, and the shaving entry holes are formed between adjacent shaving ribs.

[0008] The blade net described above further comprises a shaving plate formed by a plurality of shaving ribs connected to the first and second support plates, arranged sequentially along the slots. This structure enhances the shaving plate's load-bearing capacity, preventing deformation and collapse during the expansion of the shaving surface, and improving the product's structural reliability. Shave entry holes are formed between adjacent shaving ribs, thereby expanding the shaver entry area, reducing shaver entry difficulty, and providing a better user experience.

[0009] In one embodiment, the gap between the first support plate and the second support plate is 1 mm to 20 mm.

[0010] The gap between the first support plate and the second support plate of the above-mentioned blade net is within the range of 1mm to 20mm, which not only ensures the placement space of the inner blade assembly, but also maximizes the force limit of the shaving plate on the groove, avoids deformation of the shaving plate, and further expands the shaving area.

[0011] Preferably, the gap between the first and second support plates is set within a range of 1.5mm to 8mm, providing ample space for the inner blade assembly to prevent significant resistance and friction between the first and second support plates, which could affect the inner blade's rotation and, in turn, disrupt shaving. The maximum gap between the first and second support plates is set at 8mm, maximizing comfort for users with varying facial contours.

[0012] In one embodiment, the width of the shaving rib is 0.1 mm to 3.0 mm, and the width of the shaving entrance hole is 0.1 mm to 2.0 mm.

In addition, the curved shaving tendons on both sides also make the structure of the connection between the shaving plate and the first support plate and the second support plate smoother, prevent sharp corners from appearing on the edges, and avoid the risk of scratches. In addition, the curved shaving tendons on both sides can further increase the contact area between the blade net and the face, further optimize the shaving angle, and thus better ensure the effect of shaving the beard in one go.

[0016] In one embodiment, the shaving rib is configured to be S-shaped, V-shaped, C-shaped or elongated, or a combination of several of these shapes.

[0017] The blade net and shaving ribs can be configured in one of the following shapes: S-shaped, V-shaped, C-shaped, or long strips, or a combination of these shapes.

[0068] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0070] A blade net, a method for preparing a blade net, and a razor according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0071] like Figures 1 to 6As shown, this embodiment discloses a knife net, including: a first support plate 11, the first support plate 11 is enclosed, and a through hole 101 is formed on the inner side of the first support plate 11; a second support plate 12, the second support plate 12 is located on the outer side of the first support plate 11, the second support plate 12 is arranged opposite to the first support plate 11, the second support plate 12 is arranged along the circumference of the first support plate 11, and a groove 14 is formed between the second support plate 12 and the first support plate 11, and both sides of the groove 14 are open; a shaving plate 13, one side of the shaving plate 13 is connected to the first support plate 11, and the other side of the shaving plate 13 is connected to the second support plate 12, the shaving plate 13 covers one side of the groove 14, and a plurality of beard entry holes 132 are provided on the shaving plate 13, and the plurality of beard entry holes 132 are arranged along the shaving plate 13.

[0072] The present application discloses a blade net, which facilitates the assembly of external blades by forming a groove 14 between the first support plate 11 and the second support plate 12. At the same time, the first support plate 11 and the second support plate 12 are connected through the shaving plate 13 to facilitate the support of the shaving plate 13, thereby avoiding collapse caused by the shaving plate 13 not being supported. The cooperation of the first support plate 11, the second support plate 12 and the shaving plate 13 can effectively expand the shaving surface. While expanding the shaving surface, the shaving plate 13 can be well supported to avoid deformation of the shaving plate 13, thereby improving the user experience of the product. When the shaving surface needs to be expanded, it is only necessary to expand the area of ​​the through hole of the first support plate 11 and the gap between the first support plate 11 and the second support plate 12, thereby effectively improving the user experience of the product.

[0073] like Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further defines: the shaving plate 13 includes a plurality of shaving tendons 131, one side of the plurality of shaving tendons 131 is connected to the first support plate 11, and the other side is connected to the second support plate 12, the plurality of shaving tendons 131 are arranged in sequence along the notch of the groove 14, and shaving inlet holes 132 are formed between adjacent shaving tendons 131.

[0074] The aforementioned blade net further comprises a shaving plate 13 formed by a plurality of shaving ribs 131 connected to the first support plate 11 and the second support plate 12, and arranged sequentially along the notches of the slot 14. This structure enhances the load-bearing capacity of the shaving plate 13, preventing deformation and collapse of the shaving plate 13 during the expansion of the shaving surface, and improving the structural reliability of the product. Hair entry holes 132 are formed between adjacent shaving ribs 131, thereby expanding the hair entry area, reducing the difficulty of hair entry, and providing a better user experience.

[0075] Furthermore, in this embodiment, the gap between the first support plate 11 and the second support plate 12 is 1 mm to 20 mm.

[0076] In the above-mentioned blade net, the gap between the first support plate 11 and the second support plate 12 is in the range of 1mm to 20mm, which not only ensures the placement space of the inner blade assembly, but also maximizes the force limit of the shaving plate on the groove 14, avoids deformation of the shaving plate 13, and further expands the shaving area.

[0077] Preferably, the gap between the first and second support plates is set within a range of 1.5mm to 8mm, providing ample space for the inner blade assembly to prevent significant resistance and friction between the first and second support plates, which could affect the inner blade's rotation and, in turn, disrupt shaving. The maximum gap between the first and second support plates is set at 8mm, maximizing comfort for users with varying facial contours.

[0078] In this embodiment, the width of the shaving rib 131 is 0.1 mm to 3.0 mm, and the width of the shaving entrance hole 132 is 0.1 mm to 2.0 mm.

[0079] The aforementioned blade net further features a width range of 0.1mm to 3.0mm for the shaving ribs 131, further increasing the strength of each shaving rib 131, thereby comprehensively improving the strength of the shaving plate 13, enhancing the structural stability of the blade net, and preventing the shaving plate from deforming under pressure. The width range of the beard entry holes 132 is 0.1mm to 2.0mm, ensuring that the entry holes 132 can smoothly and easily insert long or curly beards.

[0080] like Figure 4 As shown, in this embodiment, both sides of the shaving tendon 131 are bent.

[0081] In the above-mentioned blade net, the shaving ribs 131 are curved on both sides, and the two sides of the shaving ribs are fixedly connected to the first support plate 11 and the second support plate 12 respectively. The curved design can further improve the structural strength of the shaving ribs 131, prevent the shaving plate 13 from deforming, and improve the sealing between the shaving plate 13 and the first support plate 11 and the second support plate 12, preventing shaved beards from spilling out from the connection between the shaving plate 13 and the first support plate 11 and the second support plate 12, affecting the cleanliness and hygiene of the blade net. In addition, the curved sides of the shaving ribs 131 also make the structure of the connection between the shaving plate 13 and the first support plate 11 and the second support plate 12 smoother, prevent sharp corners from occurring, and avoid the risk of scratches. In addition, the curved sides of the shaving ribs 131 can further increase the contact area between the blade net and the face, further optimize the shaving angle, and thus better ensure the effect of shaving the beard in one go.

[0082] In this embodiment, the shaving rib 131 is configured to be S-shaped, V-shaped, C-shaped or a strip, or a combination of several of these shapes.

[0083] The blade net and shaving ribs 131 can be configured in an S-shaped, V-shaped, C-shaped, or long strip shape, or a combination of these shapes. In particular, the S-shaped or C-shaped configuration provides the best results, ensuring good beard cutting performance while minimizing skin damage.

[0084] like Figure 4 As shown, in this embodiment, the side of the shaving plate 13 away from the groove 14 forms a beard entry surface, and the side of the shaving plate 13 connected to the first support plate 11 or the second support plate 12 forms a connecting surface. The distance between the beard entry surface and the connecting surface is 0mm to 2.0mm.

[0085] The blade net described above further comprises a beard entry surface on the side of the shaving plate 13 facing away from the groove 14, and a connecting surface on the side where the shaving plate 13 connects to the first support plate 11 or the second support plate 12. The spacing between the beard entry surface and the connecting surface is 0 mm to 2.0 mm. Preferably, by providing a certain spacing between the beard entry surface and the connecting surface, beards can be easily introduced into the groove from all sides, thereby further increasing the shaving area and improving shaving efficiency.

[0086] like Figure 4 As shown, in this embodiment, the thickness of the shaving plate 13 is 0.02 mm to 0.3 mm.

[0087] The blade net and shaving plate 13 have a thickness within the range of 0.02 mm to 0.3 mm, ensuring the sharpness and cutting performance of the shaving plate while also meeting the rigidity requirements of the shaving plate, thereby improving the overall quality of the shaving plate. Furthermore, while meeting the structural strength requirements, the shaving plate 13 is lightweight and reduces the amount of raw materials used, thereby saving manufacturing costs.

[0088] In this embodiment, the first support plate 11 includes a first support portion, a first bending portion and a first connecting portion, which are connected in sequence, and the side of the first connecting portion away from the first bending portion is connected to the shaving plate 13; the second support plate 12 includes a second support portion, a second bending portion and a second connecting portion, which are connected in sequence, and the side of the second connecting portion away from the second bending portion is connected to the shaving plate 13; the first support portion and the second support portion are bent toward the side where the groove 14 is located.

[0089] In the blade net described above, the first connecting portion connects the first support portion and the first bend of the first support plate 11; the second connecting portion connects the second support portion and the second bend of the second support plate 12. This structure further strengthens the ends of the first and second connecting portions, avoiding the disadvantage of lower strength resulting from the first and second connecting portions being identical in thickness. Furthermore, the first and second supporting portions bend toward the side where the groove 14 is located, facilitating connection to the shaving plate.

[0090] In this embodiment, the first support plate 11, the second support plate 12 and the shaving plate 13 are integrally provided.

[0091] The blade net, the first support plate 11, the second support plate 12 and the shaving plate 13 are integrally arranged, thereby improving structural stability and facilitating production.

[0092] like Figure 5 and Figure 6 As shown, in this embodiment, the first support plate 11, the second support plate 12 and the shaving plate 13 enclose a shaving groove, and the transverse cross-section of the shaving groove is one of a dome-shaped, a flat-topped, a tunnel-shaped, and a rectangular shape. Preferably, the transverse cross-section of the shaving groove is a dome-shaped or a flat-topped shape.

[0093] The above-mentioned blade net, the first support plate 11, the second support plate 12 and the shaving plate 13 enclose a shaving groove, and the transverse cross-section of the shaving groove is one of a dome shape, a tunnel shape, and a rectangle. The above-mentioned design can further improve the structural strength between the first support plate, the second support plate and the shaving plate 13 to prevent deformation.

[0094] like Figure 1 and Figure 2 As shown, in this embodiment, the first support plate 11 is provided with a first flange on a side away from the shaving plate 13, and the first flange extends toward the through hole; and / or the second support plate 12 is provided with a second flange on a side away from the shaving plate 13, and the second flange extends toward the side away from the groove 14.

[0095] The blade net described above improves the structural strength of the first support plate 11 and / or the second support plate 12 by providing a flange structure on the side of the first support plate 11 and / or the second support plate 12 away from the shaving plate 13. Furthermore, the flange structure can also cushion the sharpness of the first support plate 11 and / or the second support plate 12, preventing the risk of cuts to the user during use.

[0096] like Figure 1 As shown, in this embodiment, the first support plate 11 is annular, and the second support plate 12 is annular.

[0097] The blade net, with its first and second support plates 11 and 12 being annular in structure, can increase the shaving contact area while also improving the strength of the blade net structure. Furthermore, the annular structure of the first and second support plates 11 and 12 is simple in structure and manufacturing, facilitating mass production.
