As shown in fig. 1, 14 and 16, the present embodiment provides a shaving unit 11, a shaver unit 30, a shaving head 10 and a shaver 20. The shaver unit 30 has a foil 31 and the above-mentioned shaving unit 11, a plurality of shaver units 30 are provided in the shaving head 10, and the plurality of shaver units 30 may be arranged in the shaving head 10 at equal intervals around the center of the shaving head 10.

The shaving head 10 is applied to a shaver 20, and is specifically disposed on a handle 21 of the shaver 20, and a driving mechanism in the handle 21 is drivingly connected to a ceramic blade 11 in the shaving head 10 and drives the shaving unit 11 to perform a rotational motion or the like with respect to a blade net 31 of the shaving head 10. The shaver 20 may particularly be a rotary shaver.

Specifically, in a first aspect, the present embodiment provides a shaving unit 11, which includes an impeller 12 and blades 13 disposed on the impeller 12. In the present embodiment, there are a plurality of blades 13, and the plurality of blades 13 are annularly arranged on the cutter head 12 around the center of the cutter head 12.

More specifically, as shown in fig. 1 and 3, one side of the blade 13 toward the moving direction thereof is formed with a front cutting edge 14, and the front cutting edge 14 has at least two valleys.

Referring to fig. 1, a shaving head 10 according to an embodiment of the present application is further described below: the shaving assembly 11 of the present embodiment is provided with a blade 13, the blade 13 has a front cutting edge 14, the front cutting edge 14 faces one side of the rotation direction of the cutter 12, so that the front cutting edge 14 can move relative to the cutter net 31 of the shaver 20 to complete the shaving action, and the cutting line of the front cutting edge 14 is designed to have at least two valleys 16, so as to increase the length of the cutting line, so that the contact area between the cutting edge 14 and the cutter net 31 of the shaver 20 is larger, so that the cutting edge 14 can shave more beards per unit time, and thus the shaving efficiency of the shaver 20 is significantly improved without increasing the operating power of the driving mechanism in the shaver 20. Meanwhile, by designing the edge line of the front cutting edge 14 to have at least two valleys 16, the total length of the edge line of the front cutting edge 14 can be significantly increased without increasing the volume of the blades 13, thereby improving the shaving efficiency of the shaver 20.

In other embodiments of the present application, as shown in FIG. 2, the valleys 16 of the leading cutting edge 14 are recessed in a direction opposite the direction of rotation of the impeller 12. Specifically, aiming at the sinking direction of each valley 16, the sinking direction of the valley 16 is opposite to the rotating direction of the cutter head 12, so that on one hand, the edge line of the front cutting edge 14 can be positioned on one plane, and the shaving efficiency is improved, and on the other hand, the two-dimensional processing from the rotating direction of the cutter head 12 to the rotating direction of the cutter head 12 of the edge line of the front cutting edge 14 can be realized, and the processing difficulty of the front cutting edge 14 is simplified.

In other embodiments of the present application, the valleys 16 of the leading cutting edge 14 are either continuous or spaced. Specifically, in the present embodiment, the valleys 16 of the front cutting edge 14 may be continuously arranged, that is, the valleys 16 are continuously distributed on the edge line of the front cutting edge 14 end to end, so as to further increase the total length of the edge line of the front cutting edge 14, and further improve the shaving efficiency of the front cutting edge 14.

In this embodiment, the valleys 16 of the front cutting edge 14 may also be arranged at intervals, and the valleys 16 may be distributed on the edge line of the front cutting edge 14 at equal intervals or at unequal intervals. Through making each valley 16 be interval arrangement, so also can be when expanding the sword line length of preceding cutting edge 14, also can effectively control the processing degree of difficulty of the sword line of preceding cutting edge 14.

In other embodiments of the present application, as shown in fig. 2 and 4, the valleys 16 are rounded or pointed or straight. Specifically, in this embodiment, the valleys 16 may be rounded, so that the stress concentration at each valley 16 of the front cutting edge 14 can be significantly reduced, the possibility of cracks generated by the front cutting edge 14 is significantly reduced, and the overall structural strength of the blade 13 is further improved, so that the blade 13 is not easily broken during high-speed movement. Especially when the blade 13 is a ceramic blade, the filleted design of each valley 16 can significantly reduce the risk of cracking and ceramic removal of the ceramic blade.

In this embodiment, the valleys 16 may also be sharp-angled, which may make the edge lines at the valleys 16 sharper, thereby further improving the shaving efficiency of the front cutting edge 14.

In this embodiment, some of the valleys 16 may be rounded and other portions of the valleys 16 may be pointed. Alternatively, the valleys 16 near the two ends of the edge line of the front cutting edge 14 may be rounded, and the valleys 16 in the middle of the edge line of the front cutting edge 14 may be pointed, so as to prevent the two ends of the edge line of the front cutting edge 14 from cracking, and to take account of the sharpness of the edge line of the front cutting edge 14.

In this embodiment, the valley 16 may also be flat. The valley 16 being straight may mean that the bottom of the valley 16 is straight, or that both the side edges and the bottom of the valley 16 are straight. By making the valley 16 straight, the difficulty of processing the valley 16 can be reduced, and the manufacturing cost of the blade 13 can be reduced.

In other embodiments of the present application, the number of valleys 16 of the leading cutting edge 14 may be two, as shown, and the configuration of both valleys 16 may be rounded or pointed, or rounded and pointed, respectively. And, both valleys 16 are straight; alternatively, the two valleys 16 may be angular and straight, respectively. And, the two valleys 16 are rounded and flat, respectively. It is hereby expressly understood that each of the configurations of the two or more valleys 16 may be angular, or straight, in any combination or merely singular configuration.

In the present embodiment, as shown in fig. 5 and 6, the front cutting edge 14 is formed at opposite ends thereof with the crests 15 extending in the moving direction of the blade 12, and the two valleys 16 are formed with the crests 15 therebetween. Specifically, in the present embodiment, the convex peak 15 refers to a convex portion extending toward the moving direction of the cutter disc 12 and flush with or protruding from the edge line of the front cutting edge 14, and by forming the convex peak 15 on the edge line of the front cutting edge 14, the length of the edge line is further increased, thereby further improving the shaving efficiency of the front cutting edge 14.

In other embodiments of the present application, the peaks 15 may be rounded, pointed, or flat. Similarly, the valley 16 is straight, the peak 15 may be straight, the top of the peak 15 may be straight, or both the top and the side edges of the peak 15 may be straight. Specifically, by rounding the peaks 15, the possibility of cracks in the peaks 15 during long-term use can be significantly reduced, thereby prolonging the service life of the blade 13. By making the peaks 15 pointed, the sharpness of the edge line of the front cutting edge 14 can be improved. By making the peak 15 straight, it is also possible to reduce the difficulty of processing the peak 15.

Illustratively, as shown in fig. 7, the peaks 15 at opposite ends of the edge line of the leading cutting edge 14 are rounded. Specifically, the two opposite ends of the blade line are both provided with the convex peaks 15 in a fillet shape, so that the front cutting edge 14 is subjected to fillet processing at the position where the front cutting edge 14 is most prone to crack, cracks are prevented from being generated at the two ends of the front cutting edge 14, and the overall structural strength of the blade 13 is further improved.

Illustratively, there is at least one peak 15 between opposite ends of the edge line of the leading cutting edge 14, each peak 15 of the at least one peak 15 being pointed. Specifically, in combination with the scheme that both opposite ends of the blade line of the front cutting edge 14 are convex peaks 15, and the convex peaks 15 are rounded, on the basis, by designing each convex peak 15 between the opposite ends of the blade line to be pointed, the sharpness of the front cutting edge 14 can be improved, and thus the cutting and shaving efficiency of the shaving head 10 is also improved.

Illustratively, as shown in fig. 5, at least one peak 15 is present between opposite ends of the edge line of the leading cutting edge 14, and each peak 15 of the at least one peak 15 is rounded. Similarly, in combination with the scheme that the two opposite ends of the edge line of the front cutting edge 14 are both the convex peaks 15, and the convex peaks 15 are in the shape of rounded corners, on the basis, the convex peaks 15 between the two opposite ends of the edge line are designed into the shape of rounded corners, so that the probability of cracks at the convex peaks 15 is reduced, and the overall structural strength of the blade 13 is further improved.

Illustratively, as shown in fig. 7, two adjacent peaks 15 of the edge line of the front cutting edge 14 are rounded and angular. Specifically, by making two adjacent peaks 15 rounded and angular, respectively, it is possible to maintain a balance between the sharpness of the edge line of the front cutting edge 14 and the overall structural strength. On the one hand, the presence of rounded peaks 15 significantly reduces the chance of cracking of the edge line of the front cutting edge 14, while the presence of pointed peaks 15 preferably increases the sharpness of the front cutting edge 14 and thus the cutting and shaving efficiency of the shaving head 10.

In other embodiments of the present application, as shown in fig. 8 and 9, a straight line or crest 15 is formed between adjacent valleys 16 of the leading cutting edge 14, the crest 15 extending in the direction of movement of the impeller 12. Specifically, a straight line may be formed between two adjacent valleys 16 of the front cutting edge 14, that is, two adjacent valleys 16 are connected by the straight line, so that the processing difficulty of the front cutting edge 14 may be reduced. And the peaks 15 can be formed between two adjacent valleys 16, and two adjacent valleys 16 and peaks 15 can be connected seamlessly to form a curved edge line similar to a wavy line.

In other embodiments of the present application, the configuration of any valley 16 of a preceding blade 13 is different from the configuration of a valley 16 of a succeeding blade 13 corresponding to the valley 16 in the rotational direction of the impeller 12. Specifically, in the present embodiment, the preceding blade 13 and the following blade 13 refer to two blades 13 that are distributed back and forth in the rotation direction of the cutter head 12. And corresponding to the valley 16 of the preceding blade 13 and the valley 16 of the succeeding blade 13 means that the two valleys 16 are on the same motion trajectory. In this manner, by making the configuration of any one of the valleys 16 of the preceding blade 13 different from the configuration of the valley 16 of the following blade 13 corresponding to that valley 16, the shaving efficiency of the shaving assembly 11 for shaving hairs after one rotation is significantly improved.

Similarly, in the rotation direction of the cutter head 12, the configuration of any one of the peaks 15 of the previous blade 13 and the configuration of the peak 15 of the subsequent blade 13 corresponding to the peak 15 may also be different. This also significantly improves the shaving efficiency of the shaving assembly 11 after one rotation.

In other embodiments of the present application, the blade 13 is a ceramic blade. Specifically, the blade 13 may be made of a metalized ceramic material such as zirconia, and the cutter head 12 may be made of metal and an alloy thereof, or the blade 13 and the cutter head 12 may be integrally made of a metalized ceramic material by thermocompression bonding or 3D printing.

Alternatively, the ceramic blade can also be formed by mixing and pressing ferrite, nickel ferrite or tungsten steel powder subjected to magnetizing treatment and ceramic powder. The ceramic blade has better magnetism, so that when the ceramic blade is impacted and fragments appear, the fragments can be adsorbed by the ceramic blade, the phenomenon that the fragments are broken away is effectively prevented, and the use safety of the ceramic blade and the shaver is further improved.

In other embodiments of the present application, as shown in fig. 12 and 13, the side of the blade 13 facing away from its direction of movement is formed with a trailing cutting edge 17. In particular, by providing the rear cutting edge 17, the rear cutting edge 17 can also effect shaving of hairs, thereby improving the shaving efficiency of the shaving unit 11.

In other embodiments of the present application, the trailing cutting edge 17 is concave or straight. By making the rear cutting edge 17 concave, which also corresponds to an increased length of the rear cutting edge 17, the shaving efficiency of the shaving unit 11 is further improved.

In other embodiments of the present application, the concave shape may be an arc shape or a V shape, or a straight shape that is concave inward, etc. Specifically, referring to the edge line configuration of the leading cutting edge 14, the edge line configuration of the trailing cutting edge 17 may also include various combinations of an arc shape or a V shape, and a straight shape that is inwardly recessed.

Illustratively, the trailing cutting edge 17 is a curved line, which may be in particular a wavy line. In particular, by defining the curved line specifically as a wavy line, this also increases the contact area of the rear cutting edge 17 and the blade net 31, thereby also increasing the efficiency of the rear cutting edge 17 in cutting beard.

In other embodiments of the present application, as shown in FIG. 13, the curve is a curve that is convex outward toward the trailing cutting edge 17. In particular, this can reduce the manufacturing process cost of the edge line of the rear cutting edge 17 while significantly reducing the chance of cracking of the edge line of the rear cutting edge 17.

In other embodiments of the present application, as shown in FIG. 14, the blade 13 is formed with side edge lines 18 along opposite sides from the leading cutting edge 14 to the trailing cutting edge 17, the side edge lines 18 being arcuate. Specifically, the side edge line 18 refers to an edge line formed at the edge of the blade 13 corresponding to opposite sides of a line formed between the front cutting edge 14 and the rear cutting edge 17 of the blade 13. By making the side edge lines 18 arcuate, the chance of cracking of the side edge lines 18 is also significantly reduced, thereby better enhancing the overall structural strength of the blade 13.

Optionally, the two side edge lines 18 are respectively bent towards directions away from each other, so that no sharp corner occurs at the joint of the two side edge lines 18 and the front cutting edge 14 and the rear cutting edge 17, thereby avoiding the phenomenon of stress concentration at the joint, further significantly reducing the probability of cracks at the joint, and further improving the overall structural strength of the blade 13.

Alternatively, the bending direction of the rear cutting edge 17 may be the side facing away from the moving direction of the blade 13. The bending direction of the rear cutting edge 17 is back to one side of the movement direction of the blade 13, so that the outline of the overall overlooking projection of the blade 13 is more rounded, unnecessary sharp corners can be reduced as far as possible, the stress concentration phenomenon at the joint of the rear cutting edge 17 of the blade lines 18 on the two sides can be further reduced, and the overall structural strength of the blade 13 is further improved.

In other embodiments of the present application, the number of radians of the rounded corners formed at the peaks 15 and valleys 16 is between 0.3 π and 2/3 π. Specifically, the radian numerical formula is as follows:

arc degree is a x (pi/180 °);

wherein a is the central angle degree, and pi is the circumference value.

It can be seen that the central angle of the fillet formed at the peak 15 and the valley 16 is greater than or equal to 60 ° and less than or equal to 120 °, and by making the central angle of the fillet formed at the peak 15 and the valley 16 greater than or equal to 60 ° and less than or equal to 120 °, on one hand, the arrangement density of the peak 15 and the valley 16 is ensured to be appropriate, and the increase in the manufacturing cost of the blade 13 due to the large number of the peak 15 and the valley 16 is avoided. On the other hand, it is also preferable to reduce the stress concentration at the peaks 15 and the valleys 16.
