AI Technical Summary
Over time, the blade teeth of a static blade are prone to wear or deformation, affecting shaving performance and durability.
The blade tooth section is equipped with a protruding structure, including protruding tooth protrusions and ribs. Combined with the design of the tooth material removal groove and the base material removal groove, the blade structure strength is enhanced and the cutting effect is optimized.
The overall structural strength and cutting effect of the razor blades have been improved, enhancing safety and durability, reducing the risk of wear and deformation, and providing a comfortable user experience.

Abstract
Claims
1. A shaving razor blade construction comprising a static blade body (1) having a blade tooth portion (2), characterized in that: The edge of the cutting tooth part (2) away from the stationary knife body (1) protrudes to form a protruding structure. The two ends of the protruding structure extend toward both sides of the stationary knife body (1) and connect with the stationary knife body (1). The cutting tooth part (2) has a cutting tooth group (14) composed of a number of spaced cutting teeth (3). The cutting teeth (3) and the cutting tooth part (2) on both sides of the cutting teeth (3) are respectively recessed to form a tooth material removal groove (15) and a base material removal groove (16). The protruding structure includes a tooth protrusion formed on the side of the tooth material removal groove (15) away from the stationary knife body (1) and a protruding rib (6) on the side of the base material removal groove (16) away from the cutting tooth group.
2. The shaving razor blade structure of claim 1 wherein: The tooth protrusion (7) has a width W1 along the length of the cutting tooth (3), and the width from the side of the protrusion (6) that is connected to the wall of the substrate material removal groove (16) to the side of the protrusion (6) away from the center of the stationary knife body (1) is W2, where W2 > W1.
3. The shaving razor blade structure of claim 1 wherein: The height from the top of the tooth protrusion (7) to the bottom of the toothed material removal groove (15) is H1, and the height from the top of the protruding rib (6) to the bottom of the base material removal groove (16) is H2, where H1 = H2.
4. The shaving razor blade structure of claim 1 wherein: The height from the top of the tooth protrusion (7) to the bottom of the toothed material removal groove (15) is H1, and the height from the top of the protruding rib (6) to the bottom of the base material removal groove (16) is H2, wherein H1 < H2.
5. The shaving razor blade structure of claim 2, wherein: A tooth groove (8) is formed between adjacent cutting teeth (3), the depth of the tooth groove (8) is D1, the substrate material removal groove (16) has a groove plane (9) and an arc surface (10) extending from the groove plane (9) toward the rib (6), the side of the arc surface (10) away from the groove plane is connected to the rib (6), the width of the groove plane (9) is D2, and D2 > D1 / 2.
6. The shaving razor blade structure of claim 5, wherein: The rib (6) has an outer arc surface (17), an inner arc surface (18), and a top plane (19). The outer arc surface (17) and the inner arc surface (18) are respectively disposed on both sides of the top plane (19). The inner arc surface (18) is connected to the arc surface (10). The arc surface (10) is configured with an inwardly concave arc structure, and the inner arc surface (18) is configured with an outwardly convex arc structure.
7. The shaving razor blade structure of claim 1 wherein: The rib (6) includes a front rib (21) and a side rib (22). The front rib (21) is located on the side of the substrate material removal groove (16) away from the stationary knife body (1). The side rib (22) is formed by the front rib (21) extending from the end away from the cutting tooth group (14) along the edge of the substrate material removal groove (16) toward the stationary knife body (1).
8. The shaving razor blade structure of claim 5, wherein: The cutting tooth (3) has a cutting surface (11), the groove plane (9) is parallel to the cutting surface (11), and the thickness of the groove plane (9) to the cutting surface (11) is H3, where H3 ≤ 0.5 mm.
9. The shaving razor blade structure of claim 3, wherein: The cutting tooth (3) has an upper surface (13), and the height from the upper surface (13) of the cutting tooth (3) to the top of the tooth protrusion (7) is ≤0.5mm.
10. The shaving razor blade structure of claim 5, wherein: The cutting surface (11) of the cutting tooth (3) protrudes to form the cutting edge tooth protrusion (12).
11. The razor blade structure according to claim 1, characterized in that: The stationary blade body (1) and the blade tooth part (2) have an inclined surface (20).
