Description

Technical Field

[0001] The present invention relates to a shaving tool, and more particularly to a shaving blade capable of improving skin feel and a shaving device using the blade. Background Art

[0002] To facilitate hair trimming, existing razor blades are equipped with a plurality of spaced teeth at one end. The blades cut hair using cutting edges located along the edges of the teeth. To ensure effective shaving and control production costs, existing razor blades are relatively thin, typically less than 2 mm. This results in sharp teeth at the end of the razor blade, which can easily injure the skin during use. This poses a safety hazard, particularly when trimming the hair of infants and young children.

[0003] CN113815022A discloses a cutter head structure for a hair clipper and a hair clipper. The disclosed technical solution is to add an isolation structure between the shaving blade and the skin, and provide a protruding second connecting portion at the end of the isolation structure. The first connecting portion and the second connecting portion are used to separate the bottom surface and end surface of the blade teeth from the skin, thereby preventing the blade teeth from piercing the skin during use and improving the safety of the hair clipper.

[0004] Although the above structure can prevent the blade teeth from piercing the skin during use, the need for an additional isolation structure not only increases the material cost and assembly cost of the hair clipper; secondly, the superposition of the isolation structure and the thickness of the shaving blade will inevitably increase the distance between the shaving blade and the skin, making the hair clipper unable to adapt to the trimming needs of short hair (also known as inch hair or buzz cut). Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a shaving blade and a shaver with improved skin feel. By adding grinding grooves to the upper surface of the teeth of the shaving blade, a boss is formed at the front end of each tooth. The boss is used to eliminate the sharpness of the front end of each tooth, which not only prevents the teeth from piercing the skin during use; but also improves the skin feel of the teeth in contact with the skin by rounding the edges of the boss, thereby improving the comfort of use.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is a shaving blade with enhanced skin feel, comprising a substrate; the substrate has a skin-contacting working surface in contact with the skin and a cutting working surface cooperating with the movable knife; a plurality of blade teeth are arranged at one end of the substrate and the hair guide grooves between each blade tooth pass through the skin-contacting working surface and the cutting working surface; viewed from any side direction perpendicular to the cutting working surface on both sides of the substrate (which can also be regarded as the positive projection direction of both sides of the substrate), a first processing groove is provided on at least one side of the cutting working surface and the skin-contacting working surface of the substrate at the end where the blade teeth are set, so that the end of each blade tooth forms a boss higher than at least a partial surface of the blade tooth, and the edge of each boss is rounded; wherein, taking the cutting working surface of the substrate as a reference, the distance H2 between the highest point of the boss at the end of each blade tooth and the cutting working surface is one quarter to three quarters of the thickness T1 of the substrate.

[0007] Preferably, the first processing groove is arranged on the skin-contacting working surface of the substrate so that the boss at the end of the tooth is higher than at least a part of the upper surface of the tooth, and the edge of the boss is rounded.

[0008] Preferably, the height H1 of the boss at the end of each tooth is greater than one third of the thickness H2 of the end of the tooth.

[0009] Preferably, the first processing groove passes through both sides of the skin-contacting working surface of the substrate, so that both sides of the skin-contacting working surface of the substrate and the end of each tooth form a boss respectively.

[0010] Preferably, the first processing groove is formed by at least a first processing surface and a second processing surface. The first processing surface makes the end of the blade tooth of the skin-contacting working surface of the substrate be inclined, and the thickness of the substrate and the blade tooth gradually becomes thinner; the second processing surface forms bosses on both sides of the substrate and the ends of each blade tooth, and each boss is higher than the two sides of the substrate and at least the partial upper surface of each blade tooth.

[0011] Preferably, the front end edge of each blade tooth on the cutting working surface of the substrate and the front end edge of the substrate are respectively provided with arc chamfers.

[0012] Preferably, when viewed from any side direction perpendicular to the cutting working surface on both sides of the substrate, a second processing groove is provided on the cutting working surface and the skin-contacting working surface of the substrate at one end where the teeth are set, so that the ends of each tooth on the cutting working surface and the skin-contacting working surface respectively form an inner boss and an outer boss that are higher than at least a partial surface of the tooth, and the edges of the inner boss and the outer boss are rounded.

[0013] Preferably, the height H4 of the outer boss provided at the end of each tooth on the cutting working surface is less than or equal to the height H5 of the inner boss provided at the end of each tooth on the skin-contacting working surface.

[0014] Preferably, with the cutting working surface of the substrate as a reference, the distance H4 between the highest point of the outer boss and the cutting working surface is less than half of the thickness T2 of the substrate.

[0015] Preferably, when viewed from either side of the substrate perpendicular to the cutting surface, the distance H3 between the highest point of the inner boss and the highest point of the outer boss is one quarter to three quarters of the thickness T2 of the substrate.

[0016] On the basis of the above-mentioned shaving blades, the applicant has also proposed a technical solution for a shaver, which includes any one or more combinations of the above-mentioned shaving blades for improving skin feel.

[0017] The present invention has the beneficial effect of adding a processing groove to one end of the base plate where the teeth are provided, so that the ends of the teeth on the skin-contacting working surface and / or the cutting working surface respectively form a boss with a smoothed edge. The boss not only provides protection by preventing the ends of the teeth from puncturing the skin during use, thereby improving the safety of the shaving blade. In addition, when in use, the boss at the end of the teeth can also act like a comb, stimulating the nerves of the head, accelerating blood circulation and oxygen supply to the head skin, thereby creating a more comfortable skin feel and improving the comfort of the shaving blade.

[0028] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 4 As shown, the present invention provides a shaving blade with enhanced skin feel, comprising a substrate 1 made of metal or ceramic material. The substrate 1 has a skin-contacting working surface 11 for contacting the skin and a cutting working surface 12 for cooperating with a movable blade. A plurality of cutting teeth 2 are disposed at one end of the substrate 1, with hair guide grooves 3 between each cutting tooth 2 extending through the skin-contacting working surface 11 and the cutting working surface 12. This facilitates the entry of hair into the hair guide grooves 3 between the cutting teeth 2. As the movable blade oscillates back and forth along the cutting working surface 12 of the substrate 1, hair entering the hair guide grooves 3 can be trimmed. When viewed from either side of the substrate 1 perpendicular to the cutting working surface 12 (i.e., in any orthographic projection direction of the substrate 1), a first machining groove 4 is provided on at least one of the cutting working surface 12 and the skin-contacting working surface 11 of the substrate 1, located at the end where the cutting teeth 2 are located. This forms a boss 5 at the end of each cutting tooth 2, extending above at least a portion of the surface of the tooth 2. The edges of each boss 5 are rounded. The so-called rounding treatment refers to rounding the edges of the boss 5 and the end of the tooth 2, so that the edges of the boss 5 and the end of the tooth 2 have a smooth effect, avoiding the boss 5 and the tooth 2 from scratching the skin when in contact with the skin, and improving the comfort of the tooth 2 when in contact with the skin. A first processing groove 4 is added to one end of the tooth 2 on the substrate 1 so that the end of the tooth 2 on the skin-contacting working surface 11 and / or the cutting working surface 12 respectively forms a boss 5 with a smooth edge. The boss 5 not only plays a protective role, avoiding the end of the tooth 2 from piercing the skin during use, but also improves the safety of the shaving blade. In addition, when in use, the boss 5 at the end of the tooth 2 can also play a role similar to a comb, stimulating the nerves of the head, accelerating blood circulation and blood oxygen supply to the head skin, thereby producing a more comfortable skin feel and improving the comfort of using the shaving blade.

[0030] Secondly, the existing protective structures at the ends of the teeth 2 are essentially independent plastic structures, such as the plastic isolation structure disclosed in CN113815022A. This not only increases production costs but also requires additional assembly. Furthermore, during use, there is a clearance between the protective structure and the ends of the teeth 2, which can easily trap hair and cause hair pulling, resulting in a stinging sensation during hair trimming. However, the use of first machining grooves 4 on the teeth 2 on the skin-contacting working surface 11 and / or cutting working surface 12 of the substrate 1 to form bosses 5 at the ends of the teeth 2 not only facilitates production and processing but also effectively reduces assembly clearance, preventing hair pulling during use and improving the user comfort of the shaving blade during hair trimming.

[0031] During the hair trimming process, in most cases, only the skin-contacting working surface 11 comes into contact with the head skin. To enhance the skin feel and comfort during hair trimming, the first processing groove 4 is provided on the skin-contacting working surface 11 of the substrate 1, so that the boss 5 at the end of the blade tooth 2 is higher than at least a portion of the upper surface of the blade tooth 2, and the edge of the boss 5 is rounded. The first processing groove 4 is provided on the skin-contacting working surface 11 of the substrate 1, thereby forming the boss 5 at the end of the blade tooth 2. In this way, when in use, the boss 5 at the end of each blade tooth 2 can act like a comb, stimulating the head nerves, accelerating blood circulation and blood oxygen supply to the head skin, thereby creating a more comfortable skin feel and improving the comfort of shaving.

[0032] To ensure that each tooth 2 at one end of the shaving blade stimulates the scalp nerves and enhances skin feel during use, the height H1 of the boss 5 at the end of each tooth 2 is greater than one-third of the thickness H2 of the tooth 2 end. Based on the cutting surface 12 of the substrate 1, the distance H2 between the highest point of the boss 5 at the end of each tooth 2 and the cutting surface 12 (i.e., the thickness H2 of the tooth 2 end) is between one-quarter and three-quarters of the substrate 1 thickness T1. In actual production, the thickness H2 of the tooth 2 end is determined based on the substrate 1 thickness T1. For example, if the substrate 1 is made of a 2 mm thick sheet, to ensure the working strength of the tooth 2, the thickness H2 of the tooth 2 end can be set to one-half of the substrate 1 thickness T1. In this case, the height H1 of the boss 5 can be set to two-thirds of the thickness H2 of the tooth 2 end. This ensures the working strength of the tooth 2 while maximizing the stimulation of the boss 5 on the scalp nerves, enhancing the skin feel of the shaving blade when in contact with the skin, and improving the user comfort of the shaver. Of course, if the thickness T1 of the substrate 1 is relatively thick, such as equal to or greater than 4 mm, considering the combined needs of trimming short hair and the need for the boss 5 to stimulate the scalp nerves, the thickness H2 of the end of the tooth 2 can be set to one-quarter, or greater than one-quarter but less than three-quarters, of the substrate 1 thickness T1, while the height H1 of the boss 5 can be set to one-third, two-thirds, or the like of the thickness H2 of the end of the tooth 2. This allows the shaving blade to meet the needs of trimming short hair while also enhancing the stimulation of the scalp nerves by the boss 5, improving the contact feel between the shaving blade and the skin during hair trimming. In short, the principle is that the greater the thickness T1 of the substrate 1, the smaller the thickness H2 of the end of the tooth 2 and the height H1 of the boss 5 can be set. Conversely, when the thickness T1 of the substrate 1 is relatively small, the thickness H2 of the end of the tooth 2 can be increased to improve the working strength of the tooth 2, and the height H1 of the boss 5 can be set relatively large to enhance the stimulation of the scalp nerves by the boss 5 and improve the skin feel. The specific setting values ​​can be determined based on the actual thickness of the substrate 1.

[0033] To facilitate the production and processing of the bosses 5 at the ends of each tooth 2, the first processing groove 4 extends through both sides of the skin-contacting working surface 11 of the substrate 1, forming bosses 5 on both sides of the skin-contacting working surface 11 of the substrate 1 and on the ends of each tooth 2. By extending the first processing groove 4 through both sides of the skin-contacting working surface 11 of the substrate 1, the bosses 5 can be formed simultaneously on both sides of the substrate 1 and on the ends of each tooth 2, greatly facilitating the processing and forming of each boss 5 and reducing production costs. If the first processing groove 4 is only provided on the upper surface of each tooth 2, the processing difficulty of the bosses 5 at the ends of the tooth 2 will be increased. Therefore, it is preferred that the first processing groove 4 extends through both sides of the substrate 1.

[0034] In order to facilitate the processing and forming of the boss 5, improve production efficiency and reduce production costs, the first processing groove 4 includes at least a first processing surface 41 and a second processing surface 42. The first processing surface 41 makes the skin-contacting working surface 11 of the substrate 1 where the blade 2 is set form an inclined shape, and the thickness of the substrate 1 and the blade 2 gradually becomes thinner; the first processing surface 41 can be formed by machining processes such as stamping and cutting. The present technical solution is preferably a stamping process to form an inclined surface and blade 2 at one end of the substrate 1 at one time, thereby improving the production efficiency of the shaving blade. The second processing surface 42 is formed by a grinding process, that is, on the basis of the first processing surface 41, a grinding process is used to form a first processing groove 4 on both sides of the substrate 1 and the upper surface of each tooth 2, thereby forming a boss 5 on both sides of the substrate 1 and the end of each tooth 2, and the edge of the boss 5 is rounded and smoothed. This not only prevents the boss 5 from scratching the skin, but also allows the boss 5 at the end of each tooth 2 to produce a comb-like effect, stimulate the nerves of the head, accelerate blood circulation and blood oxygen supply to the skin of the head, thereby producing a more comfortable skin feel and improving the comfort of using the shaving blade. Since one end of the substrate 1 where the teeth 2 are set is inclined, when the shaving blade is in use, the inclined teeth 2 on the substrate 1 can be more easily inserted into the hair clump, and the fit with the skin of the head will be better. Therefore, the boss 5 at the end of each tooth 2 can only be partially higher than the upper surface of each tooth 2. Of course, the end of the substrate 1 where the teeth 2 are set can also be flat, and the first processing groove 4 can also be set to a square, such as Figure 5 As shown, with this structure, the skin-contacting working surface 11 of the shaving blade has a relatively poor fit with the head skin. Therefore, the implementation of this embodiment is a preferred implementation.

[0035] During hair trimming, the scissors are often held in reverse to carefully trim hair stumps at specific areas, such as the sideburns or the back of the head. To prevent skin scratches, the front edges of each tooth 2 and the front edge of the base plate 1 are each provided with a circular chamfer 6 on the cutting surface 12 of the base plate 1. This circular chamfer 6 eliminates any sharpness on the side of the base plate 1 where the teeth 2 are located, effectively preventing skin scratches during fine trimming and improving safety.

[0036] Second embodiment

[0037] On the basis of the above technical solution, the applicant has also proposed another technical solution, such as Figures 6-10 As shown, when viewed from either side of the substrate 1 perpendicular to the cutting surface 12, a second machining groove 9 is provided on each of the cutting surfaces 12 and the skin-contacting surface 11 of the substrate 1 at the end where the teeth 2 are located. This allows the ends of each tooth 2 on the cutting surface 12 and the skin-contacting surface 11 to form an inner boss 7 and an outer boss 8, respectively, that are higher than at least a portion of the surface of the tooth 2. The edges of the inner boss 7 and the outer boss 8 are both rounded. By adding the second machining groove 9 to the skin-contacting surface 11 and the cutting surface 12 at the end of the substrate 1 where the teeth 2 are located, the upper and lower surfaces of the teeth 2 are formed with inner bosses 7 and outer bosses 8, respectively, and these bosses are rounded. During normal hair trimming, the inner bosses 7 at the ends of the teeth 2 on the skin-contacting surface 11 function similarly to a comb, stimulating the head nerves and accelerating blood circulation and oxygen supply to the skin, thereby creating a more comfortable feel and enhancing the user comfort of the shaving blade. When trimming hair on special parts such as the temples and the back of the head and neck, the outer boss 8 formed on the end of the teeth 2 on the cutting working surface 12 can also directly contact the skin, which can also play a role similar to a comb, stimulating the head nerves, accelerating the blood circulation and blood oxygen supply of the head skin, thereby creating a more comfortable skin feel and improving the comfort of using the shaving blade.

[0038] In actual production, the second machined groove 9 of the inner boss 7 is similar to that of the first technical solution described above, formed by machining the first machined surface 41 and the second machined surface 42. The first machined surface 41 is formed by stamping, while the second machined surface 42 is formed by grinding. The second machined groove 9 of the outer boss 8 is also formed by grinding. Since stamping and grinding are already established processes, they will not be described in detail here.

[0039] To ensure effective hair trimming at specific locations, such as the sideburns or the back of the head, the height H4 of the outer bosses 8 at the ends of each tooth 2 on the cutting surface 12 is less than or equal to the height H5 of the inner bosses 7 at the ends of each tooth 2 on the skin-contacting surface 11. Since hair trimming is primarily performed in reverse, with the cutting surface 12 of the shaving blades in contact with the skin, the height of the outer bosses 8 is less than or equal to the height of the inner bosses 7. This allows the outer bosses 8 to directly contact the skin at the sideburns or the back of the head and neck during the trimming process, stimulating the head nerves and improving skin feel while also ensuring that hair stumps are removed to the greatest extent possible, enhancing the trimming effect. While a higher height of the outer bosses 8 than the inner bosses 7 would improve skin feel, the obstruction of the outer bosses 8 would hinder hair removal, preventing the trimming objective. Therefore, this embodiment is the preferred embodiment.

[0040] To ensure a precise hair trimming effect, the distance H4 between the highest point of the outer boss 8 and the cutting surface 12 of the substrate 1 (also referred to as the height of the outer boss 8) is less than or equal to half the thickness T2 of the substrate 1. The specific setting rule is that the thicker the thickness T2 of the substrate 1, the smaller the proportion of the outer boss 8 height H4 to the thickness T2 of the substrate 1; and the thinner the thickness T2 of the substrate 1, the larger the proportion of the outer boss 8 height H4 to the thickness T2 of the substrate 1. For example, when the thickness T2 of the substrate 1 is greater than or equal to 4mm, the outer boss 8 height H4 is preferably one-quarter of the thickness T2 of the substrate 1; and when the thickness T2 of the substrate 1 is less than or equal to 2mm, the outer boss 8 height H4 is preferably one-half of the thickness T2 of the substrate 1. The specific setting can be determined by the material or thickness of the substrate 1 and is not further limited in this embodiment.

[0041] To enhance the comfort and skin feel of the shaving blades when used, the distance H3 between the highest point of the inner boss 7 and the highest point of the outer boss 8, viewed from either side of the substrate 1 perpendicular to the cutting surface 12, is between one-quarter and three-quarters of the thickness T2 of the substrate 1. The specific setting rule is that the thicker the thickness T2 of the substrate 1, the larger the distance H3 between the outer boss 8 and the inner boss 7. And the thinner the thickness T2 of the substrate 1, the smaller the distance H3 between the outer boss 8 and the inner boss 7. For example, when the thickness T2 of the substrate 1 is greater than or equal to 4 mm, the distance H3 between the outer boss 8 and the inner boss 7 is between one-quarter and one-half of the thickness T2 of the substrate 1. When the thickness T2 of the substrate 1 is less than or equal to 2 mm, the distance H3 between the outer boss 8 and the inner boss 7 is between one-half and three-quarters of the thickness T2 of the substrate 1. This ensures a good hair trimming effect while enhancing the stimulation of the scalp nerves by the outer and inner bosses 8 and 7, improving the feel of the shaving blades against the skin. The specific setting depends on the material and thickness of the substrate 1 and is not further limited in this embodiment.

[0042] On the basis of the above-mentioned shaving blades, the applicant also proposes a technical solution for a shaver, which includes any of the above-mentioned shaving blades for improving skin feel.

[0043] The above embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the scope of protection of the present invention.
