Description

Technical Field

[0001] This application relates to the field of razors, and more particularly to a razor guard, a razor head, and a razor. Background Technology

[0002] Electric shavers are a common small household appliance, mainly of two types: reciprocating and rotary. Rotary electric shavers, in particular, use the circular motion of blades to continuously cut beard hairs. They are safe and convenient to use, and offer relatively low noise and a high level of comfort during shaving, making them increasingly popular among users.

[0003] Most existing rotary electric shavers typically have a mesh cover consisting of an outer ring shaving section and an inner ring shaving section. The outer ring shaving section and the inner ring shaving section are respectively provided with an outer ring hair inlet hole and an inner ring hair inlet hole. Between the outer ring shaving section and the inner ring shaving section, there is a ring-shaped groove that increases the strength of the mesh cover. The ring groove is a V-shaped or U-shaped slot passing through the center of the ring.

[0004] Because the annular groove of the mesh reinforcement is hollow, the skin is squeezed into it during shaving, causing discomfort, hindering smooth shaving, and making it difficult to clean. Furthermore, sebum secreted by the skin accumulates in the groove, leading to bacterial growth and increasing the risk of infection. Additionally, the hollow annular groove of the mesh reinforcement makes it easy for hairs to get stuck at the end where the hair inlet connects to the reinforcement, causing pulling and reducing shaving comfort. Utility Model Content

[0005] Therefore, it is necessary to provide a razor guard, a razor head, and a razor to address the problem of poor skin feel caused by the presence of annular grooves during shaving.

The "first direction" can refer to the direction of the razor mesh cover axially away from the moving blades.

[0037] The following is in conjunction with the appendix Figure 1-5 The embodiments of this application will be described in further detail.

[0038] See Figure 1 , Figure 1 The diagram shows an overall view of a razor guard according to one embodiment of the present application. The razor guard is installed on the head part of the razor, i.e., the part that is in direct contact with the user's skin.

[0039] In this embodiment of the application, the razor mesh includes a mesh body 1 and a skin-friendly ring 2. The mesh body 1 includes an inner ring shaving part 11, a connecting part 12 and an outer ring shaving part 13 arranged sequentially from the inside to the outside. The outer ring shaving part 13 and the inner ring shaving part 11 are coaxially arranged, and the connecting part 12 is connected between the outer ring shaving part 13 and the inner ring shaving part 11 to enhance the overall structural strength of the mesh.

[0040] Combination Figure 2 and Figure 3 As shown, Figure 2 This paper shows a schematic diagram of the structure of the skin-friendly ring 2 in one embodiment of the present application. Figure 3 A cross-sectional view of a razor mesh cover according to one embodiment of this application is shown.

[0041] In some embodiments, the cross-section of the connecting portion 12 passing through the center of the annular circle is "V" shaped. A receiving groove 4 is defined between the connecting portion 12, the outer ring shaving portion 13, and the inner ring shaving portion 11. The skin-friendly ring 2 is adapted to fit into the receiving groove 4 to achieve direct contact with the skin, thereby making it less likely for the skin to be squeezed into the receiving groove 4 during shaving. This avoids the beard getting stuck at the end of the connecting portion 12 of the outer ring shaving portion 13 or the inner ring shaving portion 11, or even pulling the beard and causing discomfort, effectively improving shaving comfort.

[0042] It is understood that, depending on the design of the razor model, in some other embodiments, the cross section of the connecting part 12 passing through the center of the annular circle may also present a "U" shape or other structural form. This application does not limit this, as long as the connecting part 12 can achieve a reliable connection between the inner ring shaving part 11 and the outer ring shaving part 13.

[0043] Continue reading Figure 3 As shown, in some embodiments, the inner ring shaving part 11, the connecting part 12 and the outer ring shaving part 13 are constructed as an integral structure, that is, integrally extruded, so that the mesh cover body 1 can have strong structural strength, while also simplifying the processing and production process and improving processing efficiency.

[0044] In addition, in some embodiments, the skin-friendly ring 2 and the mesh body 1 are made of the same material, both of which are metal. The skin-friendly ring 2 is integrally cast during the casting process of the mesh body 1, so that the receiving groove 4 defined between the connecting part 12 and the inner ring shaving part 11 and the outer ring shaving part 13 is directly filled, so as to avoid the skin sinking too much into the receiving groove 4 during the shaving process.

[0045] In other embodiments, the skin-friendly ring 2 and the mesh cover body 1 adopt a separate structural design. After the mesh cover body 1 is cast, the skin-friendly ring 2 can be assembled into the receiving groove 4 by bonding or interference fit. This ensures a reliable connection between the skin-friendly ring 2 and the mesh cover body 1 and also facilitates user replacement of the skin-friendly ring 2, reducing the reduction in skin-friendly effect of the razor due to aging of the skin-friendly ring 2. In this embodiment, the skin-friendly ring 2 is preferably made of polyoxymethylene (POM) material with good skin-friendly properties. In other embodiments, the skin-friendly ring 2 can also be made of materials with other functions, such as materials with antibacterial properties.

[0046] In some other embodiments, the inner ring shaving portion 11, the connecting portion 12, and the outer ring shaving portion 13 are configured as a split structure. The inner ring shaving portion 11 and the outer ring shaving portion 13 are connected by the connecting portion 12 to achieve a detachable connection, thereby reducing the mold opening cost in the production process of the mesh cover body 1 and facilitating the free assembly of the mesh cover body 1 structure.

[0047] At this time, if the skin-friendly ring 2 and the mesh cover body 1 are made of the same material, that is, both are metal materials, the skin-friendly ring 2 can be integrally cast with the connecting part 12 to simplify the processing procedure; if the skin-friendly ring 2 and the mesh cover body 1 are made of different materials, the inner ring shaving part 11 and the outer ring shaving part 13 can be connected to the mesh cover body 1 as a whole at the connecting part 12, and then installed on the mesh cover body 1 by bonding or interference fit to achieve a reliable connection between the skin-friendly ring 2 and the mesh cover body 1. The skin-friendly ring 2 is preferably made of polyoxymethylene (POM) material with good skin-friendly properties.

[0048] Continue reading Figure 3 As shown, in some embodiments, the mesh body 1 includes a shaving contact surface 5 for contacting the skin. The shaving contact surface 5 includes an inner shaving surface 51 and an outer shaving surface 52 arranged at intervals. The surface of the inner ring shaving portion 11 is arched along the first direction F1 to form the inner shaving surface 51, and the surface of the outer ring shaving portion 13 is arched along the first direction F1 to form the outer shaving surface 52. The inner shaving surface 51 and the outer shaving surface 52 can contact the skin surface together with the top surface of the skin-friendly ring 2.

[0049] Specifically, in some embodiments, the inner ring shaving part 11 and / or the outer ring shaving part 13 are arched in cross section in the first direction F1. Because the arched structure itself has strong pressure-bearing capacity, it can improve the pressure resistance of the shaving contact surface 5 on the mesh cover body 1 during use, thereby improving the structural strength of the mesh cover body 1 and effectively extending the service life of the cover.

[0050] In some other embodiments, the inner ring shaving portion 11 and / or the outer ring shaving portion 13 are arranged in an arc shape in the first direction F1 to ensure that the shaving contact surface 5 of the mesh body 1 has a smooth structure and no protrusions appear on the surface of the shaving contact surface 5, so that the mesh body 1 is less likely to cause a scratching sensation when it comes into contact with the face, thereby improving the user's shaving experience.

[0051] In the above embodiments, the shaving contact surface 5 is constructed as an arc surface and arches towards the first direction F1. That is, in the first direction F1, the inner ring shaving portion 11 in this embodiment is set higher than the outer ring shaving portion 13. The outer surfaces of both the inner ring shaving portion 11 and the outer ring shaving portion 13 can contact the skin, and their cross-sections are both arc-shaped, which can reduce the stickiness between the shaving surface and the skin, thereby improving the skin-friendly effect. In some other embodiments, the shaving contact surface 5 is constructed as a plane, and the inner ring shaving portion 11 and the outer ring shaving portion 13 have the same height in the first direction F1, and both can contact the skin to realize the shaving operation.

[0052] Combination Figures 1 to 4 As shown, Figure 4 It shows Figure 3 A partial structural schematic diagram. After the skin-friendly ring 2 is inserted into the receiving groove 4, there is a certain distance H between the top surface of the skin-friendly ring 2 and the shaving contact surface 5 along the first direction F1. In this embodiment, the distance H between the top surface of the skin-friendly ring 2 and the shaving contact surface 5 is set to -0.2mm to 0.5mm.

[0053] Understandably, when the distance H between the top surface of the skin-friendly ring 2 and the contact surface is positive, the larger the distance H between the top surface of the skin-friendly ring 2 and the shaving contact surface 5, the more likely it is that the beard will get stuck at the connection point between the connecting part 12 and the outer ring shaving part 13 or the inner ring shaving part 11, or even pull on the beard causing discomfort, resulting in reduced shaving comfort. When the distance H between the top surface of the skin-friendly ring 2 and the shaving contact surface 5 is negative, the top surface of the skin-friendly ring 2 protrudes from the shaving contact surface 5. The larger the absolute value of the distance H, the worse the skin-friendly effect of the skin-friendly ring 2, the more difficult the contact between the skin and the shaving contact surface 5, and the more likely there will be more shaving residue.

[0054] Therefore, in this embodiment, the distance H between the top surface of the skin-friendly ring 2 and the contact surface is preferably 0.2 mm. When using the skin-friendly ring 2, the skin will not sink too much into the receiving groove 4, the razor mesh is more skin-friendly, the shaving movement is smoother, and the beard will not get stuck in the mesh connection part 12, thus avoiding discomfort caused by pulling the beard.

[0055] Combination Figures 1 to 5 As shown, Figure 5 A partial cross-sectional view of the blade head in one embodiment of this application is shown. In some embodiments, this application also provides a blade head including a moving blade 3 and a razor mesh as shown in any of the above embodiments. The moving blade 3 can be mounted on the razor mesh along a first direction F1 to achieve effective protection of human skin during shaving.

[0056] The moving blade 3 includes a support portion 31 and an outer ring blade 32 and an inner ring blade 33 connected to the end face of the support portion 31 facing the razor mesh cover. The outer ring blade 32 and the inner ring blade 33 are spaced apart from each other and concentrically arranged. In this embodiment, along the first direction F1, the outer ring blade 32 is disposed corresponding to the outer ring shaving part 13, and the blade edge of the outer ring blade 32 is in contact with the inner surface of the outer ring shaving part 13. The inner ring blade 33 is disposed corresponding to the inner ring shaving part 11, and the blade edge of the inner ring blade 33 is in contact with the inner surface of the inner ring shaving part 11. When the moving blade 3 rotates, the inner ring blade 33 and the outer ring blade 32 rotate to cut the beard entering the beard inlet.

[0057] It is understandable that during shaving, the larger the area that the blade on the moving blade 3 can cover on the shaving contact surface 5, the higher the shaving efficiency for the beard. Therefore, in this embodiment, the outer ring blade 32, the inner ring blade 33, and the corresponding outer ring shaving part 13 and inner ring shaving part 11 have all been widened.

[0058] In some embodiments, the width of the inner ring blade 33 is set to 1.3mm-2.0mm, preferably 1.5mm; the width of the outer ring blade 32 is set to 1.3mm-2.0mm, preferably 1.5mm; the inner ring width of the inner ring shaving portion 11 is set to 1.8mm-2.5mm, preferably 2.0mm; and the inner ring width of the outer ring shaving portion 13 is set to 1.8mm-2.5mm, preferably 2.0mm. It is understood that the larger the width of the inner ring blade 33 and the outer ring blade 32, the larger the effective shaving area and the faster the shaving. However, due to the requirements of structural strength and stability, the widths of the inner ring blade 33 and the outer ring blade 32 cannot be infinitely large.

[0059]

[0060] As shown in the table above, compared to the moving blades of the prior art, the outer ring blade 32 and inner ring blade 33 in this application have a larger blade width. In this embodiment, the total coverage area of ​​the inner shaving surface 51 and the outer shaving surface 52 on the surface of the mesh body 1, that is, on the shaving contact surface 5, is set to 34.97%-67.25% to increase the area that the moving blade 3 can cover during the shaving process, thereby improving shaving efficiency.

[0061] In other embodiments, this application also provides a razor (not shown) that includes a razor guard as shown in any of the above embodiments, or a razor head as shown in any of the above embodiments.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
