The static knife 1 is provided with at least one static knife shearing part 3, the static knife shearing part 3 forms static knife teeth, a shearing groove is formed between two adjacent static knife teeth, the movable knife 2 is arranged on the movable knife tooth part matched with the static knife shearing part 3, and the movable knife tooth part forms movable knife teeth. The stationary blade 1 has a first surface 4 facing the skin, and a second surface 5 opposite the first surface 4, the first surface 4 of the shaver being in contact with the skin during operation. The utility model discloses a static sword, including static blade 6 and static sword fixing base 7, static blade 6 sets up static sword shearing portion 3, static blade 6 includes static blade body 8 and the wall portion 9 that extends by static blade body 8 both sides, static sword fixing base 7 includes pedestal 37 and two relative support walls 10 that set up, the pedestal has two relative lateral margins 11, two lateral margins 11 all extend along moving 2 moving directions of sword, the pedestal is connected between two support walls 10, and is specific, support wall 10 sets up the both ends at the pedestal along moving 2 moving directions of sword. The side edge 11 supports the wall portion 9 corresponding thereto, the supporting wall 10 has two opposite end portions 12 far from the seat body, the end portions 12 support the static blade body 8, and specifically, the supporting wall 10 is the second surface 5 on which the static blade body 8 is supported. The transition between the static blade body 8 and the wall 9, and between the seat 37 and the side edge 11 is smooth. The smooth transition does not mean that the two cannot have edges and corners, but the transition is not sharp, smooth and burr-free for the safety and comfort of use.

Specifically, the seat body 37 and the corresponding support wall 10 are in arc-shaped smooth transition, and the support wall 10 and the two ends of the stationary blade 6 on the corresponding side are flush with each other along the moving direction of the moving blade 2. As shown in the figures of the present invention, the support wall 10 has two outer lateral surfaces 13, the two outer lateral surfaces 13 being flush with the two ends 12 of the stationary blade 6.

Specifically, the wall portion 9 includes a connecting surface portion 14 and a supporting surface portion 15, the connecting surface portion 14 extends from two opposite sides of the corresponding stationary blade body 8 toward the center of the blade, and the supporting surface portion 15 extends from two opposite sides of the connecting surface portion 14 toward the stationary blade holder 7. Specifically, the connecting surface portion 14 is a curved surface, an inclined surface, or a straight surface parallel to the stationary blade body 8. The support surface portion 15 may be a curved surface, an inclined surface, or a straight surface parallel to the stationary blade body 8. Specifically, the fixed blade 6 surrounds to form an insertion groove 16, the fixed blade 6 surrounds to form insertion ports 17 at two ends along the moving direction of the movable blade 2, and the insertion ports 17 are notches of the insertion groove 16. The static knife fixing seat 7 extends into the static knife 1 from the insertion port 17 to be matched with the static knife 1. The section of the supporting wall 10 in the direction perpendicular to the moving direction of the movable blade 2 can be in the form of trapezoid, rectangle, triangle, arch, "concave" shape or "convex" shape. The cross section of the supporting wall 10 in the direction vertical to the moving direction of the moving blade 2 is the same as the shape of the inserting port 17, and at least part of the outer periphery of the supporting wall 10 is connected with the static blade 6. The "same shape" herein does not mean absolutely identical, and the supporting wall 10 may be provided with a hair-discharging opening 18, so that hairs entering the inner side of the stationary knife 1 can be discharged through the hair-discharging opening in time, or the hairs are cleaned easily. Taking the stationary knife fixing seat 7 disclosed in fig. 1 to 11 as an example, on the premise of ensuring that at least a part of the supporting wall 10 is in supporting contact with the second surface 5 where the stationary knife blade body 8 is located and at the same time a part of the supporting wall is in supporting contact with the second surface 5 of the wall portion 9, a hair discharging hole may be provided in the center or the edge of the supporting wall 10, and the shape of the hair discharging hole is not limited, so that the cross-sectional shape of the supporting wall 10 provided with the hair discharging opening 18 may also change with the change of the hair beating opening.

Taking fig. 1 as an example for illustration, the stationary blade body 8 and the seat body 37 are disposed opposite to each other, the connecting surface portion 14 is a curved surface (or referred to as an arc surface) formed on both sides of the stationary blade body 8, and the supporting surface portion 15 is an inclined surface formed on both sides of the connecting surface portion 14 of the stationary blade body 8. Corresponding to the inclined supporting surface part 15, the two side edges 11 of the seat body 37 are also formed into inclined surfaces to match with the supporting surface part 15. In fig. 1, the support wall 10 is provided with a substantially trapezoidal cross section perpendicular to the moving direction of the movable blade 2, and two rows of burrs 18 are provided on the upper portion of the support wall 10. The two sides of the supporting wall 10 correspondingly support the supporting surface part 15, and the bottom of the supporting wall 10 supports the static blade body 8. Further, the optimization design is as follows: the inclination angle of the support surface portion 15 with respect to the stationary blade body 8 is the same as the inclination angle of the inclined surface of the side edge 11 with respect to the stationary blade body 8. In practical implementation, it is only necessary to arrange that the supporting wall 10 is at least partially in supporting connection with the stationary blade body 8.

Referring to fig. 3, the main difference from fig. 1 is that: the wall part 9 is perpendicular to the static blade body 8, and correspondingly, the side edge 11 of the seat body 37 and two sides of the corresponding support wall 10 form a plane parallel to the wall part 9 together, so as to support the wall part 9; the section of the supporting wall 10 perpendicular to the moving direction of the movable blade 2 is arched (or is inverted 'concave'), so that rows of burrs 18 are formed at the bottom end of the supporting wall 10.

Referring to fig. 4, the main difference from fig. 1 is that: the both ends of support face portion 15 form the straight face with static blade body 8 mutually perpendicular, flank 11 of pedestal 37 forms and the plane of straight face complex, support wall 10 is in the cross-section along moving the sword 2 moving direction and is the rectangle, and after setting up like this, flank 11 of pedestal 37 supports support face portion 15, the bottom sprag of support wall 10 static blade body 8. The part of the slot not covered by the support wall 10 forms a burr 18.

Referring to fig. 5, also, the two ends of the supporting surface 15 form straight surfaces perpendicular to the fixed blade body 8, which is different from fig. 4 mainly in that: the side edge 11 is smoothly transited from the two sides of the seat body 37, the side edge 11 forms a plane for supporting the straight surface, besides, the side edge 11 is not connected with the corresponding supporting wall 10, and after the assembly of the static blade 6 and the static blade fixing seat 7 is completed, besides forming the burr discharging opening 18 in fig. 4, the burr discharging openings 18 are also formed at the two ends of the side edge 11. When the stationary blade body 8 and the stationary blade holder 7 are assembled, the stationary blade holder 7 is inserted into the insertion slot 16 from one end of the support wall 10 through the slot of the insertion slot 16, that is, the support wall 10 faces the slot during the assembly process. After the assembly is completed, the stationary blade body 8 and the stationary blade holder 7 may be further fixed by welding, bonding, or riveting.

Taking the direction shown in fig. 6 as an example, the cross section of the supporting wall 10 along the moving direction of the movable blade 2 is the same as that of the notch, and after the assembly is completed, the bottom surface 29 and the two side surfaces 30 of the supporting wall 10 both form the support for the fixed blade body 8 at the notch position. That is, the bottom surface of the support wall 10 supports the stationary blade body 8, and the two side surfaces are at least the slope portions supporting the stationary blade body 8 depending on the form of the stationary blade body 8. In the process of assembling the static blade body 8 and the static blade fixing seat 7, the plane portion of the static blade body 8 is easily subjected to bending deformation as shown in the figure under the action of the inclined surface portion, the supporting wall 10 is in contact with the static blade 6 in the process of matching and assembling with the static blade body 8, the supporting wall 10 and the seat body of the static blade fixing seat 7 form a structure similar to an arch or an inverse U shape, the static blade fixing seat 7 is easily subjected to bending deformation along the inverse U shape under the limitation of the structure, and the deformation formed under the action of the deformation force is mutually crossed with the deformation formed by the variable body of the static blade 1. That is, the stationary blade 1 is fixed in such a manner that the microscopic deformation of the stationary blade 1, which changes to the main body, is suppressed and cancelled, and similarly, the microscopic deformation of the stationary blade main body 8, which is likely to occur in the stationary blade holder 7, is also suppressed and cancelled. Therefore, the arrangement mode of the static knife 1 has high stability of the whole static knife 1, meets the high-precision matching requirement of all parts required by the shaver in work, avoids the abrasion between the static knife 1 and the dynamic knife 1 caused by micro deformation, and effectively reduces the temperature rise; meanwhile, the shape of the static cutter 1 is kept, so that the shearing force formed between the static cutter teeth and the movable cutter teeth during shearing is guaranteed, the galling problem is avoided, and the use comfort is further improved. The static cutter teeth and the movable cutter teeth are not separated by other supporting elements, and compared with the structural design that the supporting elements are arranged between the static cutter teeth and the movable cutter teeth in the prior art, the thickness of the static cutter teeth is reduced on the whole, so that the hair cutter is more suitable for cutting shorter hair.

The support wall 10 may be provided only as a flat portion whose bottom surface supports the notch, and is not necessarily designed so that both side surfaces form a support for the stationary blade body 8 at the notch position. That is, the cross-sectional shape of the supporting wall 10 is not necessarily limited to be the same as or matched with the slot, and when the supporting wall 10 is configured in a rectangular shape, a triangular shape, an arched shape, a concave shape or a convex shape, a row of burrs 18 may be further formed between the supporting wall 10 or the supporting wall 10 and the slot, so that the hairs inserted into the insertion slot 16 can be easily cleaned.

In the illustrated embodiments of the present invention, a static knife seat is provided, and the support walls 10 are provided at two ends of the static knife seat as an example; it should be understood by those skilled in the art that the stationary blade fixing base 7 may be in an integral form or in a separate form, and if the stationary blade fixing base 7 is in a separate form, the supporting wall 10 may be provided at one end of each stationary blade 1 fixed to the corresponding notch, and the specific structural form of the supporting wall 10 is the same as that when one stationary blade fixing base 7 is provided.

Specifically, the stationary blade 6 has a locally recessed area 19, the locally recessed area 19 is formed on the first surface 4 or the second surface 5, and the locally recessed area 19 at least partially overlaps with the area where the stationary blade cutting part 3 is located. Specifically, referring to fig. 12, the locally recessed region 19 is formed in the stationary blade body 8 of the stationary blade cutting portion 3, and covers the stationary blade body 8 where the stationary blade cutting portion 3 is located in the longitudinal direction of the stationary blade cutting portion 3. In the illustration, the stationary blade 1 is provided with two stationary blade cutting portions 3, and the local concave region 19 is provided on the plane portions of the two stationary blade cutting portions 3, but in actual implementation, the local concave region 19 may be provided on only one plane portion, and the length of the local concave region 19 is not required to cover the length of the stationary blade cutting portion 3, that is, the local concave region 19 of the stationary blade cutting portion 3 may be provided on a certain section of the stationary blade cutting portion 3.

It is understood that, in order to maintain the strength of the stationary blade 1 and to have a blade tooth thin enough to cut shorter hairs, in practical implementation, the stationary blade cutting portion 3 may be formed on one of the stationary blade body 8, the connecting surface portion 14 or the supporting surface portion 15, and the locally recessed area 19 may be formed on at least one of the stationary blade body 8, the connecting surface portion 14 or the supporting surface portion 15.
