Description

Technical Field

[0001] This utility model relates to the field of shaver technology, and in particular to a shaver head and foil assembly and a shaver. Background Technology

[0002] Currently, most rotary shavers use a straight groove (located in the foil) with a straight blade in the shaving head. When the blade rotates, it works with the foil to cut the beard. Longer hairs mainly enter the shaving track from the sides of the groove and are cut within the track. However, the straight groove design has a significant drawback: during cutting, the outward shearing component causes hairs to escape, resulting in a poor shaving experience with stinging and pulling sensations. Utility Model Content

[0003] The purpose of this invention is to provide a blade head and foil assembly and a razor that prevents beard hairs from escaping during shaving, making the shaving process more comfortable.

[0004] In a first aspect, this utility model provides a blade head and blade mesh assembly, comprising:

[0005] The shaving net has a first center, a shaving track, multiple hair inlets and multiple mesh ridges disposed on the shaving track, the hair inlets and mesh ridges being distributed alternately, the mesh ridges having shaving edges, the shaving edges having a first starting point, a middle point and a second starting point, the first starting point being the intersection of the shaving edge and the outer side of the shaving track, the second starting point being the intersection of the shaving edge and the inner side of the shaving track, and the middle point being located at the middle position of the shaving track; and a blade head disposed within the shaving net, the blade head including a blade disc and multiple rotating blades mounted on the blade disc, the blade disc having a second center, the rotating blades having cutting edges, the area through which the cutting edges rotate coincides with the shaving track, and the cutting edges facing the shaving edges;

[0028] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1-8 As shown, some embodiments of the present invention provide a blade head and blade mesh assembly, including: a blade mesh 1 and a blade head 2.

[0030] The shaving foil 1 has a first center 11, a shaving track 12, multiple hair inlets 13 and multiple mesh ridges 14 disposed on the shaving track 12, with the hair inlets 13 and mesh ridges 14 distributed alternately. Each mesh ridge 14 has a shaving edge 15, which has a first starting point 151, a midpoint 152, and a second starting point 153. The first starting point 151 is the intersection of the shaving edge 15 and the outer side of the shaving track 12, and the second starting point 153 is the intersection of the shaving edge 15 and the inner side of the shaving track 12. The midpoint 152 is located in the middle of the shaving track 12. Specifically, the distance from the midpoint 152 to the outer side of the shaving track 12 is equal to the distance from the midpoint 152 to the inner side of the shaving track 12.

[0031] The shaving head 2 is located inside the shaving net 1. The shaving head 2 includes a shaving disc 21 and a plurality of rotating blades 22 mounted on the shaving disc 21. The shaving disc 21 has a second center 211. The rotating blades 22 have blades 221. The area through which the blades 221 rotate coincides with the shaving track 12. The blades 221 face the shaving edge 15.

[0032] In this embodiment, the line connecting the first starting point 151 and the middle point 152 is a, the line connecting the first starting point 151 and the first center 11 is b, and the angle between a and b is α1; the line connecting the middle point 152 and the second starting point 153 is c, and the angle between c and b is α2, thus satisfying α1≠α2.

[0033] During operation, the drive unit drives the blade head 2 to rotate, at which time the rotating blade 22 rotates in the shaving track 12 and cooperates with the shaving edge 15 to cut the beard.

[0034] Based on the above structural configuration, the line connecting the first starting point 151 and the middle point 152 of the shaving edge 15 is a, the line connecting the first starting point 151 and the first center 11 is b, and the angle between a and b is α1; the line connecting the middle point 152 and the second starting point 153 is c, and the angle between c and b is α2. Thus, α1≠α2 is satisfied. In this way, the shaving edge 15 is curved, which prevents the beard from escaping outward during cutting and makes the shaving process more comfortable.

[0035] like Figure 7 As shown, in some embodiments, the blade 221 has a first endpoint 222 and a second endpoint 223. The first endpoint 222 is located on the side of the second endpoint 223 away from the second center 211. The line connecting the first endpoint 222 and the second endpoint 223 is e, and the line connecting the second endpoint 223 and the second center 211 is f. The angle between e and f is α3, which satisfies 15° < α3 < 90°. Thus, the blade 221 is tilted forward, forming a cutting angle with the hair inlet 13, which can effectively gather the hair in the shaving track 12.

[0036] like Figure 6 and 8 As shown, in some embodiments, the blade 221 has an inwardly concave arc shape or an outwardly convex arc shape. The inwardly concave arc shape of the blade 221 helps to improve the ability to gather beard hairs outside the shaving track 12, while the outwardly convex arc shape helps to push the beard hairs outward.

[0037] In some embodiments, the shaving track 12 is convex upwards, and the corresponding blade 221 is also convex upwards. In this way, the blade 221 and the foil 1 work together better to cut hair, making the use of the foil 1 more comfortable.

[0038] like Figure 4 As shown, in some embodiments, the shaving edge 15 is a continuous curved shape. This keeps the cutting process smooth.

[0039] like Figure 3 As shown, in some embodiments, the shaving track 12 is annular, and the center of the shaving track 12 coincides with the first center 11. This allows the rotating blade 22 to rotate smoothly within the shaving track 12.

[0040] like Figure 4 As shown, in some embodiments, when the value of α1 is in the range of 0° < α1 ≤ 20°, then the value of α2 is in the range of 30° ≤ α2 ≤ 60°. Thus, a smaller α1 facilitates the entry of the beard hair, while a larger α2 allows the skin to stretch during shaving, and because the shaving edge 15 deviates to one side, it increases the difficulty of preventing shorter beard hairs from escaping and increases the success rate of capturing shorter beard hairs.

[0041] like Figure 4 As shown, in some embodiments, when the value range of α2 is 0° < α2 ≤ 20°, then the value range of α1 is 30° ≤ α1 ≤ 60°. Thus, a larger α1 improves the ability to capture whiskers, while a smaller α2 improves the ability to cut whiskers.

[0042] It should be noted that a larger α1 improves the efficiency of beard hairs entering the shaving track 12. A larger α2 effectively flattens the skin as the foil 1 slides across the skin surface, making the hair easier to cut.

[0043] like Figure 4 As shown, in some embodiments, α1 and α2 satisfy the relationship: |α2-α1|>30°. This keeps the difference between α1 and α2 within a normal range, ensuring that the shaving edge 15 is sufficiently smooth.

[0044] The rotating blade 22 is set at an upward tilt or perpendicular to the cutter head 21. It can be set according to actual needs.

[0045] In some embodiments, the first center 11 and the second center 211 are both located on the axis of the cutter head 21. This ensures that the installation position between the cutter head 2 and the cutter mesh 1 is accurate during installation.

[0046] Other embodiments of the present invention provide a razor including a blade head and foil assembly.

[0047] Based on the above-mentioned razor, the hair is prevented from escaping during the cutting process, making the shaving process more comfortable.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
