Description
Technical Field
[0001] This application relates to the field of razor technology, and in particular to a razor head and a razor. Background Technology
[0002] Razors are an essential tool for grooming hair in daily life. Razors are divided into manual and automatic types. In electric razors, the combination of a foil and moving blades is usually used to cut the hair.
[0003] In related technologies, the shaving holes of razors are mostly rectangular strips. Since the direction of facial hair growth is not uniform and varies greatly, conventional shaving holes cannot fully capture hairs with different directions, resulting in poor hair capture ability of razors, reduced shaving efficiency, and affecting the shaving cleanliness of razors and the user experience. Utility Model Content
[0004] In view of this, this application provides a razor head and a razor that can improve the capture effect of hairs in different directions and the shaving efficiency.
[0005] Specifically, the following technical solutions are included:
[0006] In a first aspect, this application provides a razor head, the razor head including a foil, the foil including a connected top cover and a side wall, the side wall being disposed around the top cover;
[0007] The top cover is provided with a plurality of shaving inlets, which are concentrically arranged along the radial direction of the top cover. Each shaving inlet includes a plurality of shaving holes spaced apart along the circumference of the top cover. Each shaving hole penetrates the top cover along the axial direction of the top cover and is bent and protrudes along the circumference of the top cover.
[0008] In this embodiment, at least one of the plurality of hair-feeding holes of the hair-feeding portion protrudes along a first direction, and at least one of the plurality of hair-feeding holes of the hair-feeding portion protrudes along a second direction, wherein the first direction is opposite to the second direction.
[0009] In the technical solution of this application, since there are multiple hair inlets, the shaving area can be increased, which is beneficial to improving shaving efficiency. Since the hair inlet holes are bent, the hair entering the hair inlet holes can be gathered under the guidance of the bent shape, preventing the hair from being pushed out of the hair inlet holes. Since the multiple hair inlet holes of at least one hair inlet protrude along a first direction, and the multiple hair inlet holes of at least one hair inlet protrude along a second direction, and the first direction is opposite to the second direction, the bending and protruding directions of at least two hair inlet parts are opposite, which can cope with complex hair growth directions, better capture hair from all parts of the skin, improve the hair gathering and capturing ability of the razor head, and improve the shaving efficiency and cleanliness of the razor, thereby enhancing the user experience.
[0010] In one possible implementation, in at least one of the whisker-feathering portions, the whisker-feathering hole has a first edge and a second edge disposed opposite to each other in the circumferential direction of the top cover, the first edge and the second edge both including an arcuate segment that extends in an arcuate shape and protrudes in the first direction or the second direction in the circumferential direction of the top cover.
[0011] In the technical solution of this application, the curvature of the "C"-shaped hair inlet hole changes evenly, and the shape is smoother and gentler, which can reduce the pulling force on the hair, reduce the irritation to the skin, and improve shaving comfort and skin feel.
[0012] In one possible implementation, the beard feed portion includes a plurality of beard feed ribs spaced circumferentially along the top cover, the gap between any two adjacent beard feed ribs forming the beard feed hole, and the central region of the beard feed ribs bulges along the axial direction of the top cover relative to at least one end of the beard feed ribs.
[0013] In the technical solution of this application, by setting the middle region of the hair inlet to rise along the axial direction of the top cover relative to at least one end of the hair inlet, the hair inlet is generally wavy, which is beneficial to guide the hair located on the side of the hair inlet into the hair inlet hole, improve the hair gathering effect, and at the same time improve shaving comfort and shaving feel.
[0014] In one possible implementation, the top cover further includes a partition, which is annular and located between two adjacent beard-feathering portions, wherein the beard-feathering bone positions of the two adjacent beard-feathering portions are connected to the partition.
[0015] The stubble inlet includes a cut section and a first stubble inlet section that are in communication with each other. The first stubble inlet section is located at one end of the cut section near the partition and extends at least partially along the axial direction of the top cover.
[0016] In the technical solution of this application, by setting the first hair-feeding section to be located at one end of the cutting section near the partition and extending at least partially along the axial direction of the top cover, the hair-catching range of the hair-feeding hole is expanded, which is beneficial to guiding the hair located in the partition section from the first hair-feeding section into the hair-feeding hole, so as to be cut in the cutting section, thereby improving the hair-feeding efficiency of the razor head and improving the shaving efficiency of the razor.
[0017] In one possible implementation, the styling hole of the outermost styling portion further includes a second styling section, which is connected to the cutting section and is located at one end of the cutting section opposite to the first styling section and extends at least partially along the axial direction of the top cover.
[0018] In the technical solution of this application, by setting a second hair inlet section, the hair-catching range of the hair inlet hole is further expanded, which is conducive to guiding the hair located on the outer edge of the blade net into the hair inlet hole from the second hair inlet section, so as to be cut in the cutting section, thereby further improving the hair-catching efficiency of the razor head and the shaving efficiency of the razor.
[0019] In one possible implementation, the width of the first and second feed segments in the circumferential direction of the top cover is greater than the width of the cutting segment in the circumferential direction of the top cover.
[0020] In the technical solution of this application, the wider first and second hair-entry sections guide more hair into the cutting section, so that the hair is fully cut, improving the hair-gathering effect, hair-entry effect and shaving efficiency of the hair-entry section.
[0021] In one possible implementation, the top cover further includes a central base, with a plurality of the tassels arranged around the central base, the central base being recessed relative to the top surface of the tassels.
[0022] In the technical solution of this application, the concave central base forms a space for temporarily storing hair, which can prevent the cut hair from clogging the hair inlet and affecting shaving efficiency. At the same time, when the central base is in contact with the skin, the hair can enter the internal space of the foil more deeply from the hair inlet, so as to be cut more thoroughly and improve the hair removal efficiency.
[0023] In one possible implementation, the razor head further includes a moving blade, which includes a connected support portion and a plurality of cutting portions, the plurality of cutting portions being adapted to the positions of a plurality of hair-feeding portions, and the moving blade being configured to rotate about the central axis of the support portion in a preset direction, wherein the preset direction is parallel to the first direction and the second direction;
[0024] The cutting section includes a plurality of cutting blades spaced apart circumferentially along the support section. Each cutting blade has a blade edge at one end away from the support section. In the orthographic projection of the cutting section onto the plane where the support section is located, the blade edge extends in an arc shape and protrudes circumferentially along the support section. The protruding direction of the blade edge is opposite to the preset direction, so that the two ends of the blade edge are located in front of the middle region.
[0025] In the technical solution of this application, the two ends of the blade are located in front of the middle area in a preset direction. During the shaving process, the two ends can initially gather and limit the hair, prevent the hair from being pushed into the hair hole, and ensure that the blade head assembly has a strong ability to gather and capture hair, thereby improving the shaving efficiency and cleanliness of the razor.
[0026] In one possible implementation, the plurality of the whisker-feeding holes located on the outermost whisker-feeding portion all protrude along the preset direction.
[0027] In the technical solution of this application, the blade and the edge of the hair inlet hole located on the outermost part of the hair inlet can form an olive-shaped cutting area, which can hug, lock and cut the hair in the hair inlet hole. Moreover, the effective cutting area of the hair inlet part located on the outermost part is the largest. Therefore, the hair-catching effect of the blade head and the shaving efficiency and cleanliness of the razor are significantly improved, the shaving time is shortened and the user experience is greatly enhanced.
[0028] In one possible implementation, the blade has a first cutting edge and a second cutting edge disposed opposite to each other along the preset direction, the first cutting edge being located in front of the second cutting edge in the preset direction, and the first edge being located in front of the second edge in the direction of protrusion of the shaving hole.
[0029] When the first cutting edge of the razor head is projected onto the plane of the support portion, and the first edge of the outermost shaving part intersects exactly with the first edge of the shaving head, the cutting area formed by the first cutting edge and the first edge is 30mm. 2 ~70mm 2 .
[0030] In the technical solution of this application, this design helps to balance the hair-catching ability of the razor head and the structural strength of the moving blades, thus avoiding a cutting area of less than 30mm. 2 This can lead to insufficient whisker-catching ability and reduced shaving efficiency, while also avoiding a cutting area larger than 70mm. 2 This can cause the cutting blade area to become too large, making the blade prone to curling or even breakage and failure.
[0031] In one possible implementation, the length of the first cutting edge is 1.7 mm to 1.9 mm.
[0032] In the technical solution of this application, while ensuring the cutting efficiency of the razor head, the rigidity of the cutting blade is prevented from decreasing due to its excessively large area.
[0033] In one possible implementation, in the orthographic projection of the cutting portion onto a plane perpendicular to the support portion, the blade extends in an arc shape and protrudes along the axial direction of the support portion, forming a preset arc, so that the two end regions of the blade are closer to the support portion than the middle region.
[0034] In the technical solution of this application, the blade surface has a smooth shape, which can better fit the feed part, thereby improving the cutting efficiency of the blade assembly.
[0035] In one possible implementation, the support portion is provided with a plurality of chip-removing grooves, which penetrate the support portion along the axial direction of the support portion, and the plurality of chip-removing grooves are spaced apart along the circumferential direction of the support portion.
[0036] In the technical solution of this application, by setting multiple chip-extraction grooves, fine hair falling from the shaving hole can be fully collected, improving the efficiency of fine hair removal and preventing fine hair from affecting the cutting work.
[0037] In one possible implementation, the position of each of the chip-leaking grooves corresponds to the position of one of the cutting blades, and in the orthographic projection of the cutting portion onto the plane where the support portion is located, the orthographic projection of the cutting blade corresponding to the chip-leaking groove is at least partially located within the area enclosed by the outline of the chip-leaking groove.
[0038] In the technical solution of this application, by setting the orthographic projection of the cutting blade corresponding to the lint drain to be at least partially located within the area enclosed by the outline of the lint drain, the collection efficiency of fine hair is further improved, so that the cut hair can fall into the lint drain and enter the hair collection chamber of the shaver, avoiding affecting the cutting work and causing cutting jamming.
[0039] In one possible implementation, the radian of the cutting edge in the orthographic projection of the cutting portion onto the plane where the support portion is located is less than or equal to 20 rad.
[0040] In the technical solution of this application, by setting the curvature of the blade to be less than or equal to 20 rad, the shaving feel of the blade head assembly is effectively guaranteed, and the blade curvature is avoided from pulling hair and skin due to insufficient smoothness when it is greater than 20 rad, which would cause user discomfort.
[0041] Secondly, this application provides a razor, the razor including the razor head provided in any embodiment of the first aspect. Attached Figure Description

[0066] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0067] Razors are an essential tool for grooming hair in daily life. Razors are divided into manual and automatic types. In electric razors, the combination of a foil and moving blades is usually used to cut the hair.
[0068] In related technologies, the shaving holes of razors are mostly rectangular strips. Since the direction of facial hair growth is not uniform and varies greatly, conventional shaving holes cannot fully capture hairs with different directions, resulting in poor hair capture ability of razors, reduced shaving efficiency, and affecting the shaving cleanliness of razors and the user experience.
[0069] To address the aforementioned technical problems, this application provides a razor head and razor that can improve the capture effect on hairs with different directions and shaving efficiency.
[0070] like Figures 1 to 6 As shown, the razor head provided in this embodiment includes a blade net 1, which includes a top cover 11 and a side wall 12 connected together, with the side wall 12 surrounding the top cover 11.
[0071] The top cover 11 is provided with a plurality of shaving inlets 111, which are concentrically arranged along the radial direction of the top cover 11. Each shaving inlet 111 includes a plurality of shaving inlets 1111 spaced apart along the circumference of the top cover 11. Each shaving inlet 1111 penetrates the top cover 11 along the axial direction of the top cover 11. The shaving inlet 1111 is bent and protrudes along the circumference of the top cover 11.
[0072] In this embodiment, at least one of the multiple hair-feeding holes 1111 of the hair-feeding part 111 protrudes along the first direction R1, and at least one of the multiple hair-feeding holes 1111 of the hair-feeding part 111 protrudes along the second direction R2, wherein the first direction R1 is opposite to the second direction R2.
[0073] The first direction R1 and the second direction R2 are directions extending around the central axis of the top cover 11. From a top-down view of the shaver head, the first direction R1 and the second direction R2 can be counterclockwise or clockwise. For example... Figure 3 As shown, the first direction R1 is counterclockwise, and the second direction R2 is clockwise.
[0074] like Figure 4 As shown, the top cover 11 is generally circular, and the side wall 12 is connected to the edge of the top cover 11 and extends along the axial direction of the top cover 11. The blade guard 1 also includes a flange 13, which is located at the end of the side wall 12 away from the top cover 11 and is disposed around the side wall 12. The flange 13 extends in a direction parallel to the radial direction of the top cover 11, and the flange 13 has a positioning notch 131, which is used to position the blade guard 1 during assembly. There may be one or more positioning notches 131, for example... Figure 3As shown, there are two positioning notches 131, which are arranged opposite each other along the radial direction of the top cover 11.
[0075] The blade mesh 1 is suitable for use with the moving blade 2 to cut hair. The top cover 11 and the side wall 12 enclose and form a receiving space 14 for accommodating the moving blade 2 and other components.
[0076] Each hair inlet 111 is annular and arranged around the central axis of the top cover 11. The multiple hair inlet holes 1111 of each hair inlet 111 are separated from each other and are roughly the same in shape. Hair can pass through the hair inlet holes 1111 and enter the receiving space 14, thereby facilitating cutting by the passive blade 2.
[0077] Since there are multiple hair inlets 111, the shaving net 1 forms a multi-level hair-catching channel, which increases the shaving area, improves shaving efficiency and cleanliness, and reduces shaving time.
[0078] The hair inlet 1111 can be in the shape of a "C", "S", "W" or "V" bend. Compared with the rectangular strip-shaped hair inlet structure, it has a longer extension length, and the hair is more likely to gather together and be cut in a concentrated manner during shaving.
[0079] Some razors on the market use curved entry holes, but all the entry holes face the same direction, making it difficult to fully capture hairs in different directions.
[0080] In the razor head provided in this application embodiment, at least two hair inlet holes 1111 of the hair inlet portions 111 protrude in opposite directions, which can more easily capture hair from all parts of the skin and is more conducive to improving shaving efficiency and cleanliness. For example Figure 3 or Figure 4 As shown, the blade net 1 has two hair-feeding parts 111. In one hair-feeding part 111, multiple hair-feeding holes 1111 are bent and protruded along the first direction R1, and in the other hair-feeding part 111, multiple hair-feeding holes 1111 are bent and protruded along the second direction R2. When the blade net 1 slides on the skin surface, the hair can be fully inserted into the hair-feeding holes 1111, thus facilitating the cutting of hair with different directions.
[0081] The razor head provided in this application embodiment has multiple hair inlets 111, which increases the shaving area and improves shaving efficiency. Since the hair inlets 1111 are bent, the hair entering the hair inlets 1111 can be gathered under the guidance of the bent shape, preventing the hair from being pushed out of the hair inlets 1111. Since the multiple hair inlets 1111 of at least one hair inlet 111 protrude along a first direction R1 and the multiple hair inlets 1111 of at least one hair inlet 111 protrude along a second direction R2, and the first direction R1 and the second direction R2 are opposite, the bending and protruding directions of at least two hair inlets 111 are opposite. This allows it to cope with complex hair growth directions, better capture hair from various parts of the skin, improve the hair gathering and capturing ability of the razor head, and improve the shaving efficiency and cleanliness of the razor, thus enhancing the user experience.
[0082] In some embodiments, in at least one shaving portion 111, the shaving hole 1111 has a first edge 1111a and a second edge 1111b disposed circumferentially opposite to each other along the top cover 11. The first edge 1111a and the second edge 1111b both include an arcuate segment 1111aa. The arcuate segment 1111aa extends in an arcuate shape and protrudes in a first direction R1 or a second direction R2 along the circumferential direction of the top cover 11, thereby making the shaving hole 1111 at least partially arcuate.
[0083] For example Figures 3 to 5 As shown, the entry holes 1111 of both entry parts 111 are partially arc-shaped, and the entry hole 1111 of one entry part 111 protrudes along the first direction R1, while the entry hole 1111 of the other entry part 111 protrudes along the second direction R2.
[0084] In the same entry hole 1111, the arc-shaped segment 1111aa of the first edge 1111a and the arc-shaped segment 1111aa of the second edge 1111b both protrude in the same direction, and the middle region of the arc-shaped segment 1111aa is closer to the front end of the protruding direction of the entry hole 1111 than the two end regions.
[0085] In the same hair inlet 1111, the arcuate segments 1111aa of the first edge 1111a and 1111aa of the second edge 1111b have approximately the same curvature, making the hair inlet 1111 roughly "C" shaped. Compared to the rectangular strip-shaped hair inlet structure, the "C" shaped hair inlet structure has a longer extension length. During shaving, the hair is more likely to gather in the middle area of the arcuate segment 1111aa and be concentrated and cut, preventing the hair from being pushed to areas outside the hair inlet 1111. This improves the hair gathering and capturing ability of the hair inlet 111, thereby improving the shaving efficiency and cleanliness of the razor.
[0086] Some shavers on the market use a V-shaped hair inlet hole in their blades. While this design improves hair capture compared to rectangular inlet holes, the abrupt change in shape at the V-shaped intersection causes noticeable pulling on the hair and skin, affecting shaving comfort. The C-shaped hair inlet hole provided in this embodiment has a more uniform curvature and a smoother, gentler shape, reducing the pulling force on the hair, minimizing skin irritation, and improving shaving comfort and feel.
[0087] In some embodiments, the beard insertion portion 111 includes a plurality of beard insertion ribs 1112 arranged circumferentially spaced along the top cover 11, the gap between any two adjacent beard insertion ribs 1112 forms a beard insertion hole 1111, and the central region of the beard insertion rib 1112 protrudes axially relative to at least one end of the beard insertion rib 1112 relative to the top cover 11.
[0088] like Figure 5 As shown, multiple beard entry points 1112 are arranged along a ring-shaped interval, and each pair of adjacent beard entry points 1112 defines a beard entry hole 1111.
[0089] The shaving head 1112 has two ends that are radially opposite to each other along the top cover 11. The middle region of the shaving head 1112 is located between the two ends. Since the middle region of the shaving head 1112 is raised along the axial direction of the top cover 11 relative to at least one end of the shaving head 1112, the position of the middle region of the shaving head 1112 is higher than the position of at least one end. That is, the middle region of the shaving head 1112 is further away from the flange portion 13 of the blade net 1 than the at least one end.
[0090] For example Figure 6 As shown, the cross-section of the beard bone position 1112 of the outer beard portion 111 is roughly arched, and the middle region of the beard bone position 1112 is higher than the two ends; the cross-section of the beard bone position 1112 of the inner side is roughly vertically flipped "L" shaped, and the middle region of the beard bone position 1112 is higher than the end near the outer side.
[0091] Optionally, the central region of the shank position 1112 has a planar surface on the side of the top cover 11 facing away from the flange portion 13 in the axial direction, or the central region of the shank position 1112 has a convex arc-shaped surface on the side of the top cover 11 facing away from the flange portion 13 in the axial direction.
[0092] In this embodiment, by setting the middle region of the beard entry point 1112 to bulge along the axial direction of the top cover 11 relative to at least one end of the beard entry point 1112, the beard entry point 1112 is generally wavy, which is beneficial to guide the hair located on the side of the beard entry part 111 into the beard entry hole 1111, improve the beard gathering effect, and at the same time improve shaving comfort and shaving feel.
[0093] In some embodiments, the top cover 11 further includes a partition 112, which is annular and located between two adjacent beard-feathering portions 111, and the beard-feathering bone positions 1112 of the two adjacent beard-feathering portions 111 are connected to the partition 112.
[0094] The stubble inlet 1111 includes a cutting section 1111c and a first stubble inlet section 1111d that are in communication with each other. The first stubble inlet section 1111d is located at one end of the cutting section 1111c near the partition 112 and extends at least partially along the axial direction of the top cover 11.
[0095] like Figure 6 As shown, the partition 112 is annular, and the two feed portions 111 are located on opposite radial sides of the partition 112. Figure 5 As shown, the cutting segment 1111c is used to cut hair in conjunction with the moving blade 2. At least a portion of the cutting segment 1111c is formed by the arcuate segment 1111aa of the first edge 1111a and the arcuate segment 1111aa of the second edge 1111b.
[0096] In this embodiment, by setting the first hair-feeding section 1111d to be located at the end of the cutting section 1111c near the partition 112 and extending at least partially along the axial direction of the top cover 11, the hair-catching range of the hair-feeding hole 1111 is expanded. This facilitates guiding the hair located in the partition 112 from the first hair-feeding section 1111d into the hair-feeding hole 1111, where it is cut in the cutting section 1111c, thereby improving the hair-feeding efficiency of the razor head and thus improving the shaving efficiency of the razor.
[0097] In some embodiments, the beard hole 1111 of the outermost beard section 1111 further includes a second beard section 1111e, which is connected to the cutting section 1111c. The second beard section 1111e is located at one end of the cutting section 1111c away from the first beard section 1111d and extends at least partially along the axial direction of the top cover 11.
[0098] like Figure 5 As shown, in the stubble inlet 1111 of the outermost stubble inlet 111, the second stubble inlet segment 1111e, the cutting segment 1111c, and the first stubble inlet segment 1111d are connected in sequence along the radial direction of the top cover 11. The second stubble inlet segment 1111e is located at the end of the cutting segment 1111c away from the partition 112, and the first stubble inlet segment 1111d is located at the end of the cutting segment 1111c close to the partition 112. The first stubble inlet segment 1111d and the second stubble inlet segment 1111e are arranged opposite each other along the radial direction of the top cover 11.
[0099] In this embodiment, by setting the second hair inlet section 1111e, the hair-catching range of the hair inlet hole 1111 is further expanded, which is beneficial to guide the hair located on the outer edge of the blade net 1 from the second hair inlet section 1111e into the hair inlet hole 1111, so that it is cut in the cutting section 1111c, thereby further improving the hair-catching efficiency of the razor head and the shaving efficiency of the razor.
[0100] In some embodiments, the width of the first feed section 1111d and the second feed section 1111e in the circumferential direction of the top cover 11 is greater than the width of the cutting section 1111c in the circumferential direction of the top cover 11.
[0101] For example, the width d1 of the cutting segment 1111c in the circumferential direction of the top cover 11 is 0.3mm to 0.34mm, and the width d2 of the first feed segment 1111d and the second feed segment 1111e in the circumferential direction of the top cover 11 is 0.32mm to 0.36mm.
[0102] By setting d1 < d2, the wider first hair inlet section 1111d and second hair inlet section 1111e are used to guide more hair into the cutting section 1111c, so that the hair is fully cut, improving the hair gathering, hair inlet effect and shaving efficiency of the hair inlet section 111.
[0103] In some embodiments, the top cover 11 further includes a central base 113, and a plurality of feed portions 111 are disposed around the central base 113, the central base 113 being recessed relative to the top surface of the feed portions 111. It is understood that the top surface of the feed portions 111 is the side surface of the feed portions 111 facing away from the flange portion 13 in the axial direction of the top cover 11.
[0104] like Figure 6 As shown, the central base 113 includes a connected base body 1131 and a base edge 1132. The base edge 1132 is disposed around the outer edge of the base body 1131. The base body 1131 is planar. The base edge 1132 protrudes outward relative to the base body 1131 along the axial direction of the top cover 11, so that the central base 113 is in the shape of a groove.
[0105] In this embodiment, the concave central base 113 forms a space for temporarily storing hair, which can prevent the cut hair from clogging the hair inlet 1111 and affecting the shaving efficiency. At the same time, when the central base 113 is in contact with the skin, the hair can enter the receiving space 14 inside the foil 1 more deeply from the hair inlet 1111, so that it can be cut off more fully, which is beneficial to improving the cleanliness of the hair shave.
[0106] In some embodiments, the razor head further includes a movable blade 2, which includes a connected support portion 21 and a plurality of cutting portions 22. The plurality of cutting portions 22 are adapted to the positions of a plurality of hair-feeding portions 111. The movable blade 2 is configured to rotate about the central axis of the support portion 21 in a preset direction, wherein the preset direction is parallel to the first direction R1 and the second direction R2. The preset direction may be in the same direction as the first direction R1 or in the same direction as the second direction R2.
[0107] The cutting section 22 includes a plurality of cutting blades 221 arranged circumferentially along the support section 21. The cutting blades 221 are provided with a blade edge 2211 at one end away from the support section 21. In the orthographic projection of the cutting section 22 on the plane where the support section 21 is located, the blade edge 2211 extends in an arc shape and protrudes circumferentially along the support section 21. The protrusion direction of the blade edge 2211 is opposite to the preset direction, so that the two ends of the blade edge 2211 are located in front of the middle region.
[0108] The moving blade 2 is disposed within the receiving space 14 of the blade mesh 1. The support part 21 is approximately circular and planar. The cutting part 22 protrudes outward relative to the support part 21. The blade edge 2211 of the cutting blade 221 is used to cooperate with the hair infeed part 111, thereby rotating and cutting hair under the drive of a motor or other driving components. Optionally, the cutting blade 221 has a cantilever structure.
[0109] The cutting blade 221 is roughly a bent, sheet-like structure, such as... Figure 8 and Figure 9 As shown, from a top-down view of the moving blade 2, the blade edge 2211 has a bent arc-shaped structure. When the moving blade 2 is configured to rotate counterclockwise, the bending and protruding direction of the blade edge 2211 is clockwise; when the moving blade 2 is configured to rotate clockwise, the bending and protruding direction of the blade edge 2211 is counterclockwise.
[0110] like Figure 9 As shown, the two ends of the blade 2211 are located in front of the middle area in a preset direction. During the shaving process, the two ends can initially gather and limit the hair, preventing the hair from being pushed into the hair hole 1111, ensuring that the head assembly has a strong ability to gather and capture hair, thereby improving the shaving efficiency and cleanliness of the razor.
[0111] In some embodiments, the plurality of hair inlet holes 1111 of the outermost hair inlet portion 111 all protrude in a predetermined direction.
[0112] The multiple hair inlet holes 1111 of the outermost hair inlet portion 111 all protrude along the first direction R1, and the preset direction is the same as the first direction R1. The multiple hair inlet holes 1111 of the inner hair inlet portion 111 all protrude along the second direction R2, and are opposite to the preset direction.
[0113] like Figure 12As shown, the edge of the blade 2211 and the edge of the hair inlet hole 1111 of the outermost hair inlet section 111 can form an olive-shaped cutting area 2213, which can hug, lock and cut the hair in the hair inlet hole 1111. Moreover, the effective cutting area of the outermost hair inlet section 111 is the largest. Therefore, the hair-catching effect of the blade head and the shaving efficiency and cleanliness of the razor are significantly improved, the shaving time is shortened and the user experience is greatly enhanced.
[0114] like Figure 2 As shown, the bending and protruding direction of the beading hole 1111 of the beading part 111 located on the inner side is the same as the bending and protruding direction of the first cutting edge 2211a of the blade 2211.
[0115] In some embodiments, the blade 2211 has a first cutting edge 2211a and a second cutting edge 2211b disposed opposite to each other along the preset direction. The first cutting edge 2211a is located in front of the second cutting edge 2211b in the preset direction, and the first edge 1111a is located in front of the second edge 1111b in the protruding direction of the shaving hole 1111.
[0116] In the orthographic projection of the razor head onto the plane where the support part 21 is located, when the first cutting edge 2211a intersects exactly with the first edge 1111a of the outermost hair-feeding part 111, the cutting area formed by the first cutting edge 2211a and the first edge 1111a is 30mm. 2 ~70mm 2 .
[0117] The first cutting edge 2211a and the first edge 1111a cooperate to cut the hair, and the area of the cutting region 2213 formed by the first cutting edge 2211a and the first edge 1111a can be 30mm². 2 40mm 2 50mm 2 70mm 2 wait.
[0118] This design helps balance the shaving head's ability to capture hair with the structural strength of the moving blade 2, preventing the cutting area from being less than 30mm. 2 This can lead to insufficient whisker-catching ability and reduced shaving efficiency, while also avoiding a cutting area larger than 70mm. 2 This can cause the cutting blade 221 to become too large, making the cutting edge 2211 prone to curling or even breakage and failure.
[0119] In some embodiments, the length of the first cutting edge 2211a is 1.7mm to 1.9mm. For example, the length of the first cutting edge 2211a can be 1.7mm, 1.8mm, 1.9mm, etc. Optionally, the length of the second cutting edge 2211b is 1.7mm to 1.9mm.
[0120] This setting ensures the cutting efficiency of the razor head while preventing the cutting blade 221 from losing rigidity due to its excessively large area.
[0121] In some embodiments, in the orthographic projection of the cutting portion 22 onto a plane perpendicular to the support portion 21, the blade 2211 extends in an arc shape and protrudes along the axial direction of the support portion 21 to form a preset arc, so that the two end regions of the blade 2211 are closer to the support portion 21 than the middle region.
[0122] like Figure 10 and Figure 11 As shown, the surface of the blade 2211 is an arc-shaped convex surface with a raised center and concave ends. The surface of the blade 2211 is smooth and gentle. The shape of the side surface of the hair inlet 1112 near the flange 13 is adapted to the preset curvature of the blade 2211 surface, so that the hair inlet 1112 can fit more closely with the blade 2211 and cut the hair quickly and thoroughly.
[0123] With this setting, the surface of the blade 2211 is rounded, which allows it to better fit the feed section 111, thereby improving the cutting efficiency of the blade assembly.
[0124] In some embodiments, the support portion 21 has a plurality of chip-removing grooves 211, which extend through the support portion 21 along the axial direction of the support portion 21, and the plurality of chip-removing grooves 211 are spaced apart along the circumferential direction of the support portion 21.
[0125] By setting multiple chip-collecting grooves 211, fine hair falling from the hair inlet 1111 can be fully collected, improving the efficiency of fine hair removal and preventing fine hair from affecting the cutting work.
[0126] In some embodiments, the position of each chip-removing groove 211 corresponds to the position of a cutting blade 221. In the orthographic projection of the cutting part 22 onto the plane where the support part 21 is located, the orthographic projection of the cutting blade 221 corresponding to the chip-removing groove 211 is at least partially located within the area enclosed by the outline of the chip-removing groove 211.
[0127] For example, such as Figure 7 and Figure 8As shown, the cutting blade 221 of the outermost cutting section 22 is located at the edge of the support section 21, and the cutting blade 221 of the inner cutting section 22 is made by stamping. After the stamping operation, multiple stamping holes 212 are formed on the support section 21. The chip removal groove 211 is interconnected with the stamping holes 212 and includes a part of the stamping holes 212, so that the multiple chip removal grooves 211 correspond one-to-one with the multiple cutting blades 221 of the inner cutting section 22.
[0128] In this embodiment, by setting the orthographic projection of the cutting blade 221 corresponding to the lint drain 211 to be at least partially located within the area enclosed by the outline of the lint drain 211, the collection efficiency of fine hair is further improved, so that the cut hair can fall into the lint drain 211 and enter the hair collection chamber of the shaver, avoiding affecting the cutting work and causing cutting jamming.
[0129] In some embodiments, the radius of the cutting edge 2211 in the orthographic projection of the cutting part 22 onto the plane where the support part 21 is located is less than or equal to 20 rad.
[0130] For example, the curvature of the blade 2211 can be 10 rad, 15 rad, 20 rad, etc. The curvature of the first edge 1111a and the second edge 1111b can be the same as the curvature of the blade 2211.
[0131] In this embodiment, by setting the curvature of the blade 2211 to be less than or equal to 20 rad, the shaving feel of the head assembly is effectively guaranteed, and the blade 2211 is prevented from pulling on the hair and skin due to its uneven shape when the curvature is greater than 20 rad, thus avoiding user discomfort.
[0132] Optionally, a reinforcing rib 2212 is provided on the side of the cutting blade 221 away from the punching hole 212. The reinforcing rib 2212 is connected to the cutting blade 221 and the support part 21 respectively. The reinforcing rib 2212 improves the structural strength of the cutting blade 221 and can prevent the cutting blade 221 from collapsing and failing.
[0133] For example, the thickness of the whisker-feathering part 111 in the axial direction of the top cover 11 is 0.1 mm to 0.14 mm, which reduces the space occupied by the whisker-feathering part 111 while ensuring whisker-catching ability.
[0134] For example, the distance between the first cutting edge 2211a and the second cutting edge 2211b is 0.5mm to 2mm, which ensures that the cutting blade 221 has reliable structural strength while saving material costs.
