Description

Technical Field

[0001] This invention relates to a static blade for a shaver and a shaver itself. Background Technology

[0002] Patent application number 201821931856.3 discloses a reciprocating razor head, specifically disclosing that: the fixed blade includes a fixed blade body, the fixed blade body has side wings extending from the left and right sides of the fixed blade body respectively, the left and right side wings extend inwards towards each other at the bottom of the fixed blade body, the side wings and the fixed blade body form left and right blade grooves with opposite openings, the fixed blade body and the side wings have a cutting part and a hair inlet hole for hair to enter the blade grooves between the fixed blade body and the side wings, the moving blade includes a moving blade body, the moving blade body has moving blade teeth extending into the left and right blade grooves on the left and right sides respectively, the bracket includes a bracket body, the bracket body has upward support arms on the left and right sides of the bracket body, the support arms are located below the side wings, the bracket and the fixed blade are provided with a connector, one end of the connector is fixed to the fixed blade body, and the other end is fixed to the bracket body, when the connector fixes the fixed blade on the bracket, the side wings press against the support arms and change the internal height of the blade grooves, thereby limiting the gap of the moving blade teeth moving up and down in the blade grooves. The fixed blade body is supported by the bracket. Specifically, the side wing is supported by a support arm that extends in the same direction as the moving blade. The support arm positions the moving blade by limiting the height of the guide groove. In this blade assembly configuration, the height of the guide groove defined by the fixed blade body and the side wing is the same as the thickness of the moving blade. This means that both the fixed blade body and the side wing are in contact with the stationary blade, resulting in a high temperature rise during use. Furthermore, because this limiting groove needs to be formed, the external contour shape of the fixed blade is also limited by its function, resulting in low applicability. Patent application number 201721669741.4 also discloses a fixed blade with another structure. The support member and the protective foil together form the fixed blade. The two sides of the support member form support walls, and the protective foil also has a wall portion symmetrical to the support walls. Both the support walls and the protective foil extend along the moving direction of the blade. This fixed blade configuration can also strengthen the fixed blade. However, the thickness of the overlapping part of the support wall and the wall portion is relatively thick, which is equivalent to increasing the thickness of the fixed blade teeth in each cutting direction. The length of the hair that can be cut will also be limited as a result. Summary of the Invention

[0003] In view of this, the present invention provides a static blade and a shaver having the static blade.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A stationary blade, which cooperates with a moving blade to cut hair in the moving direction of the moving blade, the stationary blade includes a stationary blade and a stationary blade fixing seat. The stationary blade is provided with a stationary blade cutting part, which forms stationary blade teeth. A cutting groove is formed between two adjacent stationary blade teeth. The stationary blade includes a stationary blade body and wall portions extending from both sides of the stationary blade body. The stationary blade fixing seat includes a base body and a support wall. The support wall is disposed at both ends of the base body along the moving direction of the moving blade, and the ends of the support wall support the stationary blade body.

[0006] Specifically, the base has two opposing side edges, both of which extend along the moving direction of the blade, and the side edges support the corresponding wall portions.

[0007] Specifically, the base body and the corresponding support wall have a smooth arc transition, and the two ends of the support wall and the stationary blade on the corresponding side are flush along the moving blade direction.

[0008] Specifically, the wall includes a connecting surface and a supporting surface. The connecting surface extends from two opposite sides of the corresponding stationary blade body toward the center of the blade, and the supporting surface extends from two opposite sides of the connecting surface toward the stationary blade holder. The supporting wall simultaneously supports the stationary blade body and the connecting surface.

[0009] Specifically, the connecting surface is a curved surface, an inclined surface, or a straight surface parallel to the stationary blade body.

[0010] Specifically, the support wall is provided with a burr discharge port, and the cross-section of the support wall in the direction perpendicular to the moving blade is trapezoidal, rectangular, triangular, arched, U-shaped, or convex.

[0011] Specifically, the stationary blade has insertion interfaces formed around both ends along the moving direction of the moving blade, the stationary blade fixing seat extends into the stationary blade through the insertion interfaces and cooperates with the stationary blade, the cross-sectional shape of the support wall in the direction perpendicular to the moving direction of the moving blade is the same as the shape of the insertion interface, and at least part of the outer periphery of the support wall is in contact with the stationary blade.

[0012] Specifically, the stationary blade has a first surface facing the skin and a second surface opposite to the first surface. The stationary blade has a partially recessed area formed on the first or second surface, and the partially recessed area at least partially overlaps with the area where the stationary blade shearing part is located.

[0013] Specifically, the wall of the stationary blade is inclined, and at least part of the side edge of the seat is inclined so as to fit tightly against the wall of the stationary blade.

[0014] Specifically, the wall of the stationary blade is perpendicular to the body of the stationary blade, and at least part of the side edge of the seat is parallel to the wall and thus fits tightly against the wall of the stationary blade.

[0015] The present invention also discloses a shaver having a movable blade and the aforementioned stationary blade, wherein the movable blade is provided with a movable blade tooth portion that cooperates with the shearing portion of the stationary blade, and the movable blade tooth portion forms movable blade teeth.

[0016] Specifically, the shaver also includes a moving blade support and a moving blade limiting member. The moving blade support is connected to the moving blade, and the moving blade limiting member is fixed relative to the moving blade. The moving blade limiting member is provided with a guide structure to guide and limit the movement of the moving blade. The stationary blade fixing seat is provided with a slot or hole through which the moving blade support passes.

[0017] Specifically, the shaver also includes an elastic element with an elastic force perpendicular to the direction of movement of the moving blade. One end of the elastic element is limited by the stationary blade, and the other end of the elastic element presses against the moving blade.

[0018] Specifically, the elastic element has a support portion and two elastic pre-compression portions extending from both sides of the support portion, and the elastic pre-compression portion has an arc-shaped segment that contacts the pre-compression of the moving blade.

[0019] Specifically, the transition between the stationary blade body and the wall, as well as between the base and the side edge, is smooth and rounded.

[0020] Specifically, the shaver also includes a moving blade support and an elastic element. The stationary blade fixing seat is provided with a perforation and positioning structure. The perforation provides support for the moving blade. The arrangement of the stationary blade described in this invention ensures high overall stability of the stationary blade, better meeting the high-precision matching requirements between various components required during operation of the shaver. This avoids wear between the moving and stationary blades caused by microscopic deformation and effectively reduces temperature rise. At the same time, maintaining the shape of the stationary blade ensures that the shearing force formed between the stationary blade teeth and the moving blade teeth during shearing does not cause fuzzing, further improving user comfort. The support is connected to the moving blade, and the positioning structure is interconnected with the elastic element.

[0021] The beneficial effect of the present invention is that there are no other supporting elements between the stationary blade and the moving blade. Compared with the existing structural design in which there are supporting elements between the stationary blade and the moving blade, the thickness of the stationary blade is reduced as a whole, which is more suitable for cutting shorter hair.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The core of this invention is to provide a stationary blade for a razor and a razor that uses the stationary blade, so as to simultaneously solve the problems of razor strength, cutting effect and manufacturing process.

[0041] The present invention will now be further described with reference to the accompanying drawings.

[0042] This invention provides the following technical solution:

[0043] As attached Figures 1-14As shown, this invention discloses a shaver comprising a stationary blade 1 and a movable blade 2 cooperating with the stationary blade 1. The stationary blade 1 and the movable blade 2 are configured to move relative to each other, typically cutting hair in the direction of movement of the movable blade 2. The stationary blade 1 has at least one stationary cutting portion 3, which forms stationary blade teeth, with a cutting groove formed between adjacent stationary blade teeth. The movable blade 2 has a movable blade tooth portion that cooperates with the stationary blade cutting portion 3, forming movable blade teeth. The stationary blade 1 has a first surface 4 facing the skin and a second surface 5 opposite to the first surface 4. When the shaver is in operation, its first surface 4 contacts the skin. The stationary blade 1 includes a stationary blade 6 and a stationary blade fixing seat 7. The stationary blade 6 is provided with the stationary blade shearing part 3. The stationary blade 6 includes a stationary blade body 8 and wall portions 9 extending from both sides of the stationary blade body 8. The stationary blade fixing seat 7 includes a seat body 37 and two opposing support walls 10. The seat body has two opposing side edges 11, both of which extend along the moving direction of the moving blade 2. The seat body is connected between the two support walls 10. Specifically, the support walls 10 are located at both ends of the seat body along the moving direction of the moving blade 2. The side edges 11 support the corresponding wall portions 9. The support walls 10 have two opposing ends 12 away from the seat body. The ends 12 support the stationary blade body 8. Specifically, the support walls 10 support the second surface 5 where the stationary blade body 8 is located. There is a smooth transition between the stationary blade body 8 and the wall portions 9, and between the seat body 37 and the side edges 11. The smooth transition does not mean that there can be no sharp edges between the two, but rather that for the sake of safety and comfort, the transition should not be sharp and should be smooth without burrs.

[0044] Specifically, the base 37 and the corresponding support wall 10 have a smooth arc transition, and the two ends of the support wall 10 and the corresponding stationary blade 6 are flush along the moving direction of the moving blade 2. As shown in the accompanying drawings of this invention, the support wall 10 has two outer surfaces 13, which are flush with the two ends 12 of the stationary blade 6.

[0045] Specifically, the wall portion 9 includes a connecting surface 14 and a supporting surface 15. The connecting surface 14 extends from two opposite sides of the corresponding stationary blade body 8 toward the center of the blade, and the supporting surface 15 extends from two opposite sides of the connecting surface 14 toward the stationary blade fixing seat 7. Specifically, the connecting surface 14 is a curved surface, an inclined surface, or a straight surface parallel to the stationary blade body 8. The supporting surface 15 can also be a curved surface, an inclined surface, or a straight surface parallel to the stationary blade body 8. Specifically, the stationary blade 6 forms an insertion groove 16 around its perimeter, and the stationary blade 6 forms insertion interfaces 17 around its two ends along the moving direction of the moving blade 2. The insertion interfaces 17 are the openings of the insertion groove 16. The stationary blade fixing seat 7 extends into the stationary blade 1 through the insertion interfaces 17 and mates with the stationary blade 1. The cross-section of the supporting wall 10 in the direction perpendicular to the moving blade 2 can be trapezoidal, rectangular, triangular, arched, U-shaped, or convex. The cross-sectional shape of the support wall 10 in the direction perpendicular to the moving blade 2 is the same as the shape of the insertion interface 17, and at least a portion of the outer periphery of the support wall 10 is in contact with the stationary blade 6. Here, "same shape" does not mean absolutely identical; a hair removal opening 18 can be provided in the support wall 10 to allow hair entering the inner side of the stationary blade 1 to be discharged promptly through the hair removal opening, or in other words, to facilitate hair cleaning. Figures 1-11 Taking the static blade holder 7 disclosed in the paper as an example, under the premise that at least part of the support wall 10 is in support contact with the second surface 5 where the static blade body 8 is located, and at the same time part is in support contact with the second surface 5 of the wall portion 9, a hair removal hole can be provided at the center or edge of the support wall 10. The shape of the hair removal hole is not limited. Therefore, the cross-sectional shape of the support wall 10 with the hair removal hole 18 will also change with the change of the hair removal hole.

[0046] by Figure 1 Taking an example, the stationary blade body 8 and the base 37 are arranged opposite to each other. The connecting surface 14 is a curved surface (or arc-shaped surface) formed on both sides of the stationary blade body 8, and the supporting surface 15 is an inclined surface formed on both sides of the connecting surface 14 of the stationary blade body 8. Corresponding to the inclined supporting surface 15, the two side edges 11 of the base 37 also form inclined surfaces to cooperate with the supporting surface 15. Referring to the direction shown in the figure, in Figure 1 In this design, the support wall 10 has a roughly trapezoidal cross-section in the direction perpendicular to the moving blade 2, and two bristle discharge ports 18 are provided at the upper part of the support wall 10. The support surface 15 is supported on both sides of the support wall 10, and the stationary blade body 8 is supported at the bottom of the support wall 10. Further, the optimized design is that the inclination angle of the support surface 15 relative to the stationary blade body 8 is the same as the inclination angle of the inclined surface of the side edge 11 relative to the stationary blade body 8. In practical implementation, it is sufficient to ensure that at least a portion of the support wall 10 is in contact with and supported by the stationary blade body 8.

[0047] Reference Appendix Figure 3 , and its appendix Figure 1 The main difference is that the wall portion 9 is perpendicular to the stationary blade body 8. Correspondingly, the side edge 11 of the seat body 37 and the two sides of the corresponding support wall 10 together form a plane parallel to the wall portion 9, thereby supporting the wall portion 9. The cross section of the support wall 10 in the direction perpendicular to the moving blade 2 is arc-shaped (or inverted "concave"), thereby forming a hair removal opening 18 at the bottom of the support wall 10.

[0048] Reference Appendix Figure 4 , and its appendix Figure 1 The main difference is that the two ends of the support surface 15 form straight surfaces perpendicular to the stationary blade body 8, the side edge 11 of the seat 37 forms a plane that mates with the straight surfaces, and the support wall 10 has a rectangular cross-section along the moving direction of the moving blade 2. With this configuration, the side edge 11 of the seat 37 supports the support surface 15, and the bottom of the support wall 10 supports the stationary blade body 8. The portion of the groove not covered by the support wall 10 forms the deburring opening 18.

[0049] Reference Appendix Figure 5 Similarly, the two ends of the supporting surface 15 form straight surfaces perpendicular to the stationary blade body 8, which are attached to the surface. Figure 4 The main difference is that the side edge 11 smoothly transitions from both sides of the base 37, and the side edge 11 forms a plane supporting the straight surface. Apart from this, the side edge 11 is not connected to the corresponding support wall 10. After the assembly of the stationary blade 6 and the stationary blade fixing seat 7 is completed, except for the formation of an attached... Figure 4 In addition to the bristle discharge port 18 in the center, bristle discharge ports 18 are also formed at both ends of the side edge 11. When assembling the stationary blade body 8 with the stationary blade fixing seat 7, the stationary blade fixing seat 7 extends into the insertion groove 16 through the opening of the insertion groove 16 from one end where the support wall 10 is located. That is, during assembly, the support wall 10 faces the groove opening. After assembly, the stationary blade body 8 and the stationary blade fixing seat 7 can be further fixed by welding, bonding, or riveting.

[0050] by Figure 6Taking the direction shown as an example, the cross-section of the support wall 10 along the moving direction of the moving blade 2 is the same as the cross-section of the slot. After assembly, the bottom surface and two side surfaces of the support wall 10 support the stationary blade body 8 at the slot position. That is, the bottom surface of the support wall 10 supports the stationary blade body 8, and the two side surfaces, depending on the shape of the stationary blade body 8, at least support the inclined surface of the stationary blade body 8. During the assembly of the stationary blade body 8 and the stationary blade fixing seat 7, the planar portion of the stationary blade body 8 is prone to bending deformation as shown in the figure under the action of the inclined surface. During the assembly of the support wall 10 with the stationary blade body 8, the support wall 10 contacts the stationary blade 6. The support wall 10 extends from the seat towards the stationary blade body 8, forming an arch-like or "∩"-like structure with the seat body of the stationary blade fixing seat 7. Under the constraint of this structure, the stationary blade fixing seat 7 is prone to bending deformation along the "∩". The deformation formed under this deformation force intersects with the deformation formed by the stationary blade 6. In other words, the arrangement of the stationary blade fixing seat 7 suppresses and counteracts the micro-deformation of the stationary blade body 8, and similarly, the stationary blade body 8 also suppresses and counteracts the micro-deformation easily generated by the stationary blade fixing seat 7. Therefore, this arrangement of the stationary blade 1 ensures high overall stability, better meeting the high-precision matching requirements of various components in the shaver during operation. It avoids wear between the moving and stationary blades 1 caused by microscopic deformation, effectively reducing temperature rise. Simultaneously, maintaining the shape of the stationary blade 1 ensures that the shearing force generated between the stationary and moving blades during cutting does not cause hair pulling, further improving user comfort. Since there are no other supporting elements between the stationary and moving blades, compared to existing designs with supporting elements between them, this effectively thins the stationary blades, making them more suitable for cutting shorter hairs.

[0051] The support wall 10 can be simply configured to support the flat portion at the slot on its bottom surface, without the necessity of both sides forming support for the stationary blade body 8 at the slot position. In other words, the cross-sectional shape of the support wall 10 is not necessarily limited to being the same as or matching the slot. When the support wall 10 is configured as a rectangle, triangle, arch, U-shape, or convex shape, a hair removal opening 18 can be further formed on the support wall 10 or between the support wall 10 and the slot. This configuration makes it easier to remove hair that has entered the insertion slot 16.

[0052] In the embodiments listed in this invention, the example is that a stationary knife holder is set and the support wall 10 is set at both ends of the stationary knife holder. It is not difficult for those skilled in the art to understand that the stationary knife fixing seat 7 can be in the form of a whole or in the form of separate parts. If the stationary knife fixing seat 7 is set in the form of separate parts, the support wall 10 can be set at the end of each stationary knife 1 that is fixed and corresponds to the slot. The specific structural form of the support wall 10 is the same as when a stationary knife fixing seat 7 is set.

[0053] Specifically, the stationary blade 6 has a partially recessed region 19, which is formed on the first surface 4 or the second surface 5. The partially recessed region 19 at least partially overlaps with the region where the stationary blade shearing section 3 is located. For more details, refer to… Figure 12 As shown, the partially recessed region 19 is formed on the stationary blade body 8 of the stationary blade shearing section 3, and covers the stationary blade body 8 where the stationary blade shearing section 3 is located along its length. In the figure, the stationary blade 1 is provided with two stationary blade shearing sections 3, and the partially recessed region 19 is provided on the planar portion of both stationary blade shearing sections 3. In actual implementation, the partially recessed region 19 can be provided on only one of the planar portions, and the length of the partially recessed region 19 does not necessarily need to cover the length of the stationary blade shearing section 3. That is to say, the partially recessed region 19 of the stationary blade shearing section 3 can be provided on a certain section of the stationary blade shearing section 3.

[0054] Understandably, in order to maintain the strength of the stationary blade 1 while ensuring sufficiently thin blades to cut shorter hairs, in specific implementations, depending on actual needs, the stationary blade cutting section 3 can also be formed on one of the stationary blade body 8, the connecting face 14, or the supporting face 15. Correspondingly, at least one of the stationary blade body 8, the connecting face 14, or the supporting face 15 forms the locally recessed area 19. For example... Figure 13 As shown, another type of stationary blade 6 with a partially recessed area 19 is displayed. Specifically, the arrangement of the stationary blade 6 is similar to... Figure 12 Similarly, the stationary blade shearing section 3 extends along the moving direction of the moving blade 2, but the difference is that the local recessed area 19 covers the entire area where the stationary blade shearing section 3 is located. This configuration creates a rectangular, opposing protrusion at the center of the stationary blade body 8.

[0055] like Figure 14 As shown, this invention differs from others. Figure 12 , 13 Another type of stationary blade 1 is shown. Specifically, the arrangement of the stationary blade body 8 is the same as... Figure 1 ,3 Similarly, the stationary shearing section 3 extends along the moving direction of the moving blade 2. The difference is that the stationary blade body 8 is provided with three stationary shearing sections 3, that is, relative to the attached blade 2. Figure 12 , 13 , attached Figure 14 Furthermore, a separate stationary blade shearing portion 3 is added to the stationary blade body 8. Correspondingly, the local recessed area 19 covers the stationary blade shearing portion 3 of the stationary blade body 8. Of course, the local recessed area 19 of the flat portion may also only cover part of the stationary blade shearing portion 3 of the stationary blade body 8.

[0056] The material of the stationary blade body 8 can be metal or other alloy materials with good weldability. The partially recessed area 19 can be formed in a certain way. When the wall portion 9 of the stationary blade 6 is inclined, at least part of the side edge 11 of the seat 37 is inclined, so that it can fit tightly against the wall portion 9 of the stationary blade 6.

[0057] When the wall portion 9 of the stationary blade 6 is perpendicular to the stationary blade body 8, at least a portion of the side edge 11 of the seat 37 is parallel to the wall portion 9 and thus fits tightly against the wall portion 9 of the stationary blade 6. For example... Figure 3 As shown, in the example shown, the side edge 11 is a plane perpendicular to the stationary blade body 8, that is, the side edge 11 is completely in contact with the wall portion 9.

[0058] The present invention also discloses a shaver, see attached document. Figures 1-11 The shaver has a moving blade 2 and the aforementioned stationary blade 1. Specifically, the shaver also includes a moving blade support 20 and a moving blade limiting member 21. The moving blade support 20 is connected to the moving blade 2. The moving blade limiting member 21 is fixed relative to the moving blade 2. The moving blade limiting member 21 is provided with a guide structure 22 to guide and limit the movement of the moving blade 2. The stationary blade fixing seat 7 is provided with a slot or hole through which the moving blade support 20 passes.

[0059] Specifically, see attached Figure 1 For example: The moving blade support 20 is fixed relative to the moving blade 2, and the two can be connected by welding, riveting, or snap-fitting. The base 37 of the stationary blade fixing seat 7 has a groove. The upper end of the moving blade support 20 extends out of the groove from the stationary blade fixing seat 7 and is connected to a power element. The power element has the force to drive the moving blade support 20 to reciprocate. The moving blade limiting member 21 can be configured to connect with the stationary blade fixing seat 7, so that the two are fixed relative to each other. The moving blade limiting member 21 has a guide structure 22, as shown in the attached figure. Figure 1As shown, the guide structure 22 can be a groove along the moving direction of the moving blade 2. The guide structure 22 can be formed independently by the moving blade limiting member 21, or it can be formed by the moving blade limiting member 21 being positioned opposite the base 37 or the stationary blade fixing base 7. The guide structure 22 is not limited to a groove; it can also be other structures with guiding functions that protrude relative to the moving blade limiting member 21. Furthermore, the shaver also includes an elastic member 23. The elastic member 23 has an elastic force perpendicular to the moving direction of the moving blade 2. One end of the elastic member 23 is limited by the stationary blade 1, and the other end of the elastic member 23 presses against the moving blade 2. Specifically, the elastic member 23 has a support portion 24 and two elastic pre-pressing portions 25 extending from both sides of the support portion 24, respectively. The elastic pre-pressing portion 25 has an arc-shaped section that pre-presses into contact with the moving blade 2. The elastic member 23 is also provided with a groove corresponding to the groove on the moving blade limiting member 21, and the moving blade bracket 20 passes through the groove and connects to the moving blade 2.

[0060] The moving tool limiter 21 can be fixed relative to the elastic member 23 or the stationary tool fixing seat 7. Specifically, the connection between the moving tool limiter 21 and the elastic member 23 or the stationary tool fixing seat 7 can be a fixed connection such as welding (spot welding or butt welding), secondary forming and fixing, or a detachable connection such as a snap-fit.

[0061] As attached Figure 8 , 9 As shown, the shaver may also include a stationary blade 6, a stationary blade fixing seat 7, a moving blade 2, a moving blade support 20, and an elastic element 23. That is to say, relative to the attached... Figure 1 The moving blade limiting member 21 is removed. Specifically, the stationary blade fixing seat 7 is provided with a through hole 26 and a positioning structure 27. The through hole 26 is used to connect the moving blade support 20 and the moving blade 2, and the positioning structure 27 is connected to the elastic member 23. Furthermore, the positioning structure 27 is a hole formed in the center of the stationary blade fixing seat 7, and the elastic member 23 is provided with a limiting structure 36 to limit the movement of the moving blade support 20. The limiting structure 36 is a groove formed between the elastic pre-compression portions 25. The top portions of the two elastic pre-compression portions 25 are connected to form a protruding structure that protrudes relative to the elastic pre-compression portions 25. This protruding structure matches the limiting structure 36, so that the stationary blade fixing seat 7 and the elastic member 23 form a snap-fit ​​limiting.
