Rotary electric shavers use the circular motion of the blades to continuously cut beard hair. They are safe and convenient to use, and the quiet, comfortable shaving process has made them increasingly popular.

[0003] The shaving inlet holes of the existing rotary electric shaver mesh cover are mostly straight grooves with two long edges parallel to each other. The width of each section of the shaving inlet hole is the same, and the outer ring shaving part and the inner ring shaving part have the same thickness and height. The inner ring shaving part plays a very small role. Moreover, the outer ring shaving part and the inner ring shaving part are both flat, which easily cause a sticky feeling, poor comfort, and cannot further improve the shaving efficiency and the shaving cleanliness is also poor.

The outer ring shearing surface of the outer ring shaving part and the inner ring shearing surface of the inner ring shaving part are both suitable for contact with the skin, thereby providing a rotary electric shaver with comfort, high efficiency and good shaving quality.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a mesh cover, comprising an outer ring shaving part, an inner ring shaving part and a rotating central axis, wherein the top of the outer ring shaving part is provided with an outer ring shearing surface, and the outer ring shearing surface is provided with a plurality of outer ring shaving inlet holes;

[0006] The inner ring shaving part is arranged on the inner side of the outer ring shaving part, and the top of the inner ring shaving part is provided with an inner ring shearing surface, the inner ring shearing surface is higher than the outer ring shearing surface, and the inner ring shearing surface is provided with a plurality of inner ring shaving inlet holes;

[0007] The rotation center axis is arranged inside the inner ring shaving part.

[0008] In some embodiments, the cross-sections of the outer ring shearing surface and the inner ring shearing surface are both arc-shaped, and the highest point of the arc of the inner ring shearing surface is higher than the highest point of the arc of the outer ring shearing surface.

[0009] In some embodiments, the height difference between the highest point of the arc of the inner ring shearing surface and the highest point of the arc of the outer ring shearing surface is 0.05 mm-0.50 mm.

[0010] In some embodiments, the outer ring hair inlet hole radially penetrates the outer ring shaving portion, and the outer ring hair inlet hole includes an inner hair inlet section, a shearing section, and an outer hair inlet section. The inner hair inlet section is arranged on the side of the outer ring hair inlet hole close to the inner ring shaving portion, and the outer hair inlet section is arranged on the side of the outer ring hair inlet hole away from the inner ring shaving portion. The shearing section connects the inner hair inlet section and the outer hair inlet section.

[0011] In some embodiments, the outer ring hair inlet hole is S-shaped, and the width of the outer hair inlet section and / or the width of the inner hair inlet section is greater than the width of the shearing section.

[0012] In some embodiments, the width of the inner beard entry section gradually increases toward the side closer to the inner ring shaving portion, and the width of the outer beard entry section gradually increases toward the side away from the inner ring shaving portion, and the maximum width of the outer beard entry section is greater than the maximum width of the inner beard entry section.

[0013] In some embodiments, the inner ring shearing surface thickness of the inner ring shaving portion is smaller than the outer ring shearing surface thickness of the outer ring shaving portion.

[0014] In some embodiments, the inner ring hair inlet hole does not radially penetrate the inner ring shaving portion, and the width of the inner ring hair inlet hole is smaller than the width of the outer ring hair inlet hole.

[0015] According to another aspect of the present application, a knife net assembly is further provided, comprising any one of the mesh cover and a blade of the above-mentioned preferred embodiments, wherein the blade is suitable for being installed on the rotating center axis of the mesh cover so that the outer ring cutting edge of the blade fits with the inner surface of the outer ring shaving part of the mesh cover, and the inner ring cutting edge of the blade fits with the inner surface of the inner ring shaving part of the mesh cover.

[0016] According to another aspect of the present application, a rotary electric shaver is further provided, comprising any one of the blade net assemblies of the above preferred embodiments.

[0018] 1. The inner ring shearing surface of the inner ring shaving part is higher than the outer ring shearing surface of the outer ring shaving part, which can better allow the beard to enter the inner ring beard inlet hole, thereby improving the shaving efficiency of the inner ring shaving part. The outer ring shearing surface of the outer ring shaving part and the inner ring shearing surface of the inner ring shaving part are both suitable for contacting the skin, thereby providing a rotary electric shaver with comfort, efficiency and good shaving quality.

[0019] 2. The cross-sections of the outer ring shear surface and the inner ring shear surface are both arc-shaped, which reduces the sticky feeling between the outer ring shear surface and the inner ring shear surface and the skin, and improves comfort; the outer ring beard inlet hole radially penetrates the outer ring shaving part, and long beards can more easily enter the outer ring beard inlet hole from both ends of the outer ring beard inlet hole, thereby improving the shaving efficiency of the outer ring shaving part.

[0020] 3. The width of the cutting section remains unchanged, reducing the risk of skin entering the outer ring beard entrance holes and the risk of shaving the skin; the two ends of the outer ring beard entrance holes gradually widen towards the side away from the cutting section, allowing the beard to enter the outer ring beard entrance holes faster, shortening the shaving time and improving shaving efficiency.

[0021] 4. The inner ring shaving part is designed for short beards. The thickness of the inner ring shaving part is smaller than that of the outer ring shaving part, which can improve the shaving quality.

[0022] 5. The width of the inner ring shaving hole is smaller than that of the outer ring shaving hole, which increases the strength of the inner ring shaving part. The inner ring shaving part will not be deformed and will not affect the sharpness. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance. It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be considered as the scope of protection of the present utility model.

[0036] refer to Figures 1 to 3The utility model provides a mesh cover 1, including an outer ring shaving part 11, an inner ring shaving part 12 and a rotating central axis 13. The outer ring shaving part 11 is provided with an outer ring shearing surface 111 at the top, and a plurality of outer ring beard inlet holes 112 are provided on the outer ring shearing surface 111; the inner ring shaving part 12 is arranged on the inner side of the outer ring shaving part 11, and an inner ring shearing surface 121 is provided at the top of the inner ring shaving part 12, the inner ring shearing surface 121 is higher than the outer ring shearing surface 111, and a plurality of inner ring beard inlet holes 122 are provided on the inner ring shearing surface 121; the rotating central axis 13 is arranged on the inner side of the inner ring shaving part 12.

[0037] In this embodiment, the inner ring shearing surface 121 of the inner ring shaving part 12 is higher than the outer ring shearing surface 111 of the outer ring shaving part 11, which can better allow the beard to enter the inner ring beard inlet hole 122, thereby improving the shaving efficiency of the inner ring shaving part 12. The outer ring shearing surface 111 of the outer ring shaving part 11 and the inner ring shearing surface 121 of the inner ring shaving part 12 are both suitable for contacting the skin, thereby providing a rotary electric shaver that is comfortable, efficient, and has a good shaving quality.

[0038] Specifically, the inner ring shaving part 12 and the outer ring shaving part 11 are two concentrically arranged circular rings, and a rotation center axis 13 is provided on the inner side of the inner ring shaving part 12. The outer ring shearing surface 111 at the top of the outer ring shaving part 11 and the inner ring shearing surface 121 at the top of the inner ring shaving part 12 are both suitable for contacting the skin. There are several outer ring beard inlet holes 112 distributed in a circular pattern on the outer ring shearing surface 111 of the outer ring shaving part 11, and there are several inner ring beard inlet holes 122 distributed in a circular pattern on the inner ring shearing surface 121 of the inner ring shaving part 12. The beard enters the interior of the mesh cover 1 through the inner ring beard inlet holes 122 and the outer ring beard inlet holes 112. The inner surface of the inner ring shaving part 12 and the inner surface of the outer ring shaving part 11 are both in contact with the blade edge surface. When the blade rotates, the blade edge rotates to cut off the entering beard. At the same time, the inner ring shearing surface 121 is higher than the outer ring shearing surface 111, and the beard can enter the inner ring beard inlet hole 122 more easily, which can improve the shaving efficiency of the inner ring shaving part 12 and avoid the inner ring shaving part 12 playing a very small role.

[0039] It is worth noting that the present invention lists a double-ring mesh cover 1, but is not limited to a double-ring mesh cover, and includes multi-ring mesh covers such as three-ring mesh covers, a shaving assembly containing the mesh cover 1 of the present invention, and a shaver.

[0040] Furthermore, the cross-sections of the outer ring shear surface 111 and the inner ring shear surface 121 are both arc-shaped, and the highest point of the arc of the inner ring shear surface 121 is higher than the highest point of the arc of the outer ring shear surface 111 .

[0041] In this embodiment, the cross-sections of the outer ring shear surface 111 and the inner ring shear surface 121 are both arc-shaped, which reduces the stickiness between the outer ring shear surface 111 and the inner ring shear surface 121 and the skin and improves comfort.

[0042] Specifically, the comfort of the shaver mainly depends on the feeling of the skin when the mesh 1 contacts the skin. Good comfort requires that the curved surfaces of the mesh 1 are excessively smooth, and the contact area between the inner ring shaving part 12 and the outer ring shaving part 11 of the mesh 1 and the skin should not be too large, otherwise it will easily cause a sticky feeling. Figure 2 The cross-sections of the outer ring shearing surface 111 and the inner ring shearing surface 121 are both arc-shaped, the arc radius of the outer ring shearing surface 111 is R2, and the arc radius of the inner ring shearing surface 121 is R1. The highest point of the arc of the inner ring shearing surface 121 is higher than the highest point of the arc of the outer ring shearing surface 111, and the height difference is D. There will be a certain gap between the skin and the outer ring shaving part 11 and the inner ring shaving part 12 between the two highest points. The sticky feeling between the skin and the outer ring shaving part 11 and the inner ring shaving part 12 will be significantly reduced, thereby improving the shaving comfort. Because the skin in the area with the gap will not fit with the outer ring shaving part 11 and the inner ring shaving part 12, there will be a certain angle, making it easier for the beard to enter the inner ring beard inlet hole 122 and the outer ring beard inlet hole 112, thereby improving the shaving efficiency, especially the shaving efficiency of the inner ring shaving part 12. The numerical range of D is 0.05mm-0.50mm, that is, the height difference between the highest point of the arc of the inner ring shearing surface 121 and the highest point of the arc of the outer ring shearing surface 111 is 0.05mm-0.50mm. The numerical range of D is preferably 0.15mm-0.35mm. If the value of D is too small, the inner ring shaving unit 12 will not be highlighted, while if it is too large, the outer ring shaving unit 11 will easily separate from the skin. The numerical range of R1 and R2 is 3mm-12mm, preferably 3.5mm-10mm. If the value is too small, it will be difficult to process, while if it is too large, it will not improve the comfort.

[0043] Further, refer to Figure 4 The outer ring hair inlet hole 112 radially penetrates the outer ring shaving part 11, and the outer ring hair inlet hole 112 includes an inner hair inlet section 1121, a shearing section 1122 and an outer hair inlet section 1123. The width of the outer hair inlet section 1123 and / or the width of the inner hair inlet section 1121 is greater than the width of the shearing section 1122.

[0044] In this embodiment, the outer ring beard inlet hole 112 radially penetrates the outer ring shaving part 11 , and long beards can more easily enter the outer ring beard inlet hole 112 from both ends of the outer ring beard inlet hole 112 , thereby improving the shaving efficiency of the outer ring shaving part 11 .

[0045] Specifically, the shaving efficiency of the shaver depends on how easily beards enter the outer ring beard inlet holes 112 and the inner ring beard inlet holes 122. The easier it is for beards to enter the outer ring beard inlet holes 112 and the inner ring beard inlet holes 122, the higher the shaving efficiency. The outer ring beard inlet holes 112 radially extend through the outer ring shaving portion 11 and are open at both ends, making it easier for beards to pass through the openings at both ends of the outer ring beard inlet holes 112 and enter the inner portion of the outer ring beard inlet holes 112. The outer ring beard inlet hole 112 divides the outer ring shaving part 11 into several parts. The outer ring beard inlet hole 112 is divided into an inner beard inlet section 1121, a shearing section 1122 and an outer beard inlet section 1123. The inner beard inlet section 1121 is close to the center of the outer ring shaving part 11, and the outer beard inlet section 1123 is far away from the center of the outer ring shaving part 11. The shearing section 1122 is located between the inner beard inlet section 1121 and the outer beard inlet section 1123. The shearing section 1122 is the area of ​​the outer ring beard inlet hole 112 covered when the blade rotates, so the longer the shearing section 1122 is, the larger the shaving area is. The inner beard inlet section 1121 is located on the side of the outer ring beard inlet 112 closer to the inner ring shaving section 12, while the outer beard inlet section 1123 is located on the side of the outer ring beard inlet 112 farther from the inner ring shaving section 12. The cutting section 1122 connects the inner beard inlet section 1121 and the outer beard inlet section 1123. The width of the outer beard inlet section 1123 and / or the width of the inner beard inlet section 1121 is greater than the width of the cutting section 1122. This makes it easier for beards to enter the outer ring beard inlet 112 from both ends, thereby improving shaving efficiency.

[0046] It is worth noting that, in this embodiment, the outer ring hair inlet hole 112 is preferably in an S-shape. In a modified embodiment, the outer ring hair inlet hole 112 may also be in other shapes.

[0047] Preferably, the width of the shearing section 1122 remains unchanged, the width of the inner beard entry section 1121 gradually increases toward the side close to the inner ring shaving section 12, and the width of the outer beard entry section 1123 gradually increases toward the side away from the inner ring shaving section 12, and the maximum width of the outer beard entry section 1123 is greater than the maximum width of the inner beard entry section 1121.

[0048] In this embodiment, the width of the shearing section 1122 remains unchanged, which reduces the risk of skin entering the outer ring beard inlet 112 and also reduces the risk of shaving the skin; the two ends of the outer ring beard inlet 112 gradually widen toward the side away from the shearing section 1122, so that the beard enters the outer ring beard inlet 112 faster, the shaving time is shortened, and the shaving efficiency is improved.

[0049] Specifically, the closer the inner beard entry section 1121 is to the inner side of the outer ring shaving section 11, the wider it is, with a maximum width of W1. The closer the outer beard entry section 1123 is to the outer side of the outer ring shaving section 11, the wider it is, with a maximum width of W3. W3 is greater than 1.2 times W2, and W1 is greater than 1.1 times W2. Although the larger W1 and W3 are, the better, too large W1 and W3 will result in insufficient strength of the mesh cover 1, and the range is: 1.2×W2≤W3≤2.5×W2, 1.1×W2≤W1≤2×W2. Beards mainly enter the shearing section 1122 from the outer beard entry section 1123. Long beards, in particular, mostly enter the shearing section 1122 from the outer beard entry section 1123 of the outer ring beard entry hole 112. The larger the maximum width W3 of the outer beard entry section 1123 of the outer ring beard entry hole 112, the faster the beards enter and the higher the shaving efficiency. Therefore, the maximum width of the outer whisker entry section 1123 is greater than the maximum width of the inner whisker entry section 1121.

[0050] Further, refer to Figure 5 The thickness of the inner ring shearing surface 121 of the inner ring shaving portion 12 is smaller than the thickness of the outer ring shearing surface 111 of the outer ring shaving portion 11 .

[0051] In this embodiment, the inner ring shaving portion 12 is designed for short beards. The thickness of the inner ring shaving portion 12 is smaller than that of the outer ring shaving portion 11, which can improve the shaving quality.

[0052] Specifically, the cleanness of the shaver depends on the thickness of the inner ring shaving part 12, the outer ring shaving part 11 and the width of the outer ring beard inlet hole 112, the inner ring beard inlet hole 122. The thinner the inner ring shaving part 12 and the outer ring shaving part 11 and the wider the outer ring beard inlet hole 112 and the inner ring beard inlet hole 122, the better the cleanness of the shaver. Figure 5 This is a schematic diagram of the thickness of the shaving section of the mesh cover 1, with T1 representing the thickness of the inner shaving section 12 and T2 representing the thickness of the outer shaving section 11. T1 ≤ T2. A thicker outer shaving section 11 better ensures the strength of the mesh cover 1. The T2 value range is 0.09mm-0.15mm, preferably 0.10mm-0.12mm. A smaller T2 results in insufficient mesh cover 1 strength, while a larger T2 significantly impairs shaving quality. The corresponding width W2 of the shearing section 1122 of the outer shaving inlet 112 ranges from 0.22mm-0.30mm, preferably 0.26mm-0.28mm. Given a fixed T2, a smaller W2 results in lower shaving efficiency, while a larger W2 increases the risk of skin lacerations. The numerical range of T1 is 0.06mm-0.10mm, preferably 0.07mm-0.09mm. If T1 is too small, the strength of the mesh cover 1 is not enough, and if it is too large, the shaving cleanliness will be significantly reduced. The width of the inner ring shaving hole 122 is W4, and the numerical range of W4 is 0.18mm-0.26mm, preferably 0.23mm-0.25mm. The smaller W4 is, the lower the shaving efficiency is, and the larger W4 is, the greater the risk of shaving the skin is. The outer ring is used for rough shaving to improve shaving efficiency, and the inner ring is used for fine shaving to improve shaving cleanliness.

[0053] It's worth noting that the inner ring hair inlet hole 122 does not radially penetrate the inner ring shaving unit 12, and its width is smaller than that of the outer ring hair inlet hole 112. This increases the strength of the inner ring shaving unit 12, preventing deformation and affecting sharpness. Compared to the existing mesh cover 1 on the market, the width of the outer ring hair inlet hole 112 remains unchanged, but the thickness has increased by 0.01mm, reducing the risk of shaving. However, the thickness of the inner ring shaving unit 12 and the width of the inner ring hair inlet hole 122 have both been reduced by 0.02mm, improving the cleanness of the shave without increasing the risk of shaving. The mesh cover 1 also provides sufficient strength.

[0054] Furthermore, the present application provides a knife net assembly, comprising the mesh cover 1 and the blade in any of the above embodiments, the blade being suitable for being installed on the rotating center axis 13 of the mesh cover 1, so that the outer ring cutting edge of the blade is in contact with the inner surface of the outer ring shaving part 11 of the mesh cover 1, and the inner ring cutting edge of the blade is in contact with the inner surface of the inner ring shaving part 12 of the mesh cover 1.

[0055] Furthermore, the present application provides a rotary electric shaver, comprising the blade net assembly in the above embodiment.

[0056] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
