Description

Technical Field

[0001] The present application relates to the field of cosmetic technology, and in particular to a brush head for an eyelash brush and an eyelash brush. Background Art

[0002] An eyelash brush is one of the important tools for eye makeup. Dip the brush in mascara and use it to apply a base to the eyelashes, curl and shape them, and extend the eyelashes, making them thick, distinct, and naturally long.

[0003] At present, the shape design of some mascara brush heads is not suitable for the eye shape. For example, some straight-tube brush heads are difficult to accurately cover and evenly apply to the eyelashes at the beginning and end of the eyes, resulting in the eyelashes in these areas not being fully modified, the makeup effect is not natural enough, and the eyelashes are not long enough. Summary of the Invention

[0004] The present application provides a brush head and an eyelash brush for an eyelash brush, which can achieve a longer and more natural eyelash makeup effect.

[0033] First, reference Figures 1 to 13 , an embodiment of the present application provides a brush head 1 for an eyelash brush, the brush head 1 comprising a brush rod 11, a plurality of first comb teeth 113 and a plurality of second comb teeth 114, the circumference of the brush rod 11 comprising a first side wall 111 and a second side wall 112, along the length direction X of the brush rod 11, the outer contour of the cross section of the first side wall 111 is arc-shaped and bulges away from the center line of the brush rod 11; the plurality of first comb teeth 113 are arranged on the first side wall 111, along the length direction X of the brush rod 11, the plurality of first comb teeth 113 are arranged at intervals, along the length direction X of the brush rod 11, the projection of the first comb teeth 113 has a first edge, the first edge is connected to the first side wall 111, and the first edge is an arc-shaped bulge away from the center line of the brush rod 11; the plurality of second comb teeth 114 are arranged on the second side wall 11 2. Along the length direction X of the brush rod 11, a plurality of second comb teeth 114 are arranged at intervals; wherein, along the length direction X of the brush rod 11, the brush rod 11 has a first end 11a and a second end 11b, and in the direction from the first end 11a to the second end 11b, the ends of the plurality of first comb teeth 113 away from the first side wall 111 jointly construct a first contour surface 115, and the first contour surface 115 includes a first area 115a, a second area 115b and a third area 115c connected to each other, and the distance between the first area 115a and the center line of the brush rod 11 is greater than the distance between the second area 115b and the center line of the brush rod 11, and the distance between the third area 115c and the center line of the brush rod 11 is greater than the distance between the second area 115b and the center line of the brush rod 11.

[0034] refer to Figure 1 and Figure 2 The first side wall 111 is configured to be an arc convex outward toward the center line away from the brush rod 11, and the first comb teeth 113 are provided on the first side wall 111. The projection of the first comb teeth 113 includes a first side and a second side. The first side and the second side are arranged opposite to each other, the first side is provided on the first side wall 111, and the second side is farther away from the first side wall 111 than the first side. The first side and the second side can both be arc-shaped, that is, the first comb teeth 113 are constructed as an arc-shaped structure similar to a fan. This arc-shaped structure can make the first comb teeth 113 better adapt to the natural curvature of the eyelashes, and can closely fit various parts from the root to the tip of the eyelashes. It is particularly suitable for outlining detailed areas such as the tail of the eye or the lower eyelashes, reducing blind spots in application, and making the mascara evenly cover each eyelash. Moreover, the gaps between the multiple first comb teeth 113 of the arc-shaped structure can scrape an appropriate amount of mascara. When combing the eyelashes with the multiple first comb teeth 113, the brush head 1 is rotated from the root to the tail of the eyelashes so that the mascara in the gaps between the multiple first comb teeth 113 can be evenly covered on the eyelashes, achieving a natural and distinct makeup effect.

[0035] It should be noted that the second side can also be formed into other approximately arc-shaped shapes, such as an approximately arc-shaped polygon, or an irregular edge, as long as the first comb teeth 113 can be constructed into a flat structure similar to a fan.

[0036] For example, the first comb teeth 113 may be arranged in a direction perpendicular to the length direction X of the brush rod 11, that is, the plane on which the first comb teeth 113 are located is perpendicular to the length direction X of the brush rod 11; or the first comb teeth 113 may be arranged in a direction inclined relative to the length direction X of the brush rod 11; or the first comb teeth 113 may be arranged in a spirally inclined manner on the first side wall 111. When the first comb teeth 113 are arranged in a spirally inclined manner on the first side wall 111, when applying mascara, the eyelashes are curled as the brush head moves from the root to the tail of the eyelashes, achieving a lengthening and curling effect on the eyelashes.

[0037] Along the length direction X of the brush rod 11, the distances between the first area 115a and the third area 115c and the center line of the brush rod 11 are both greater than the distance between the second area 115b and the center line of the brush rod 11, that is, the first contour surface 115 is constructed as an arc surface concave toward the center line of the brush rod 11. Specifically, along the length direction X of the brush rod 11, the lengths of the first comb teeth 113 at both ends of the first side wall 111 are greater than the length of the first comb teeth 113 in the middle of the first side wall 111; or, along the length direction X of the brush rod 11, the distances between the part of the first side wall 111 at both ends of the brush rod 11 and the center line of the brush rod 11 are greater than the distance between the part of the first side wall 111 in the middle of the brush rod 11 and the center line of the brush rod 11, and at the same time, the lengths of the plurality of first comb teeth 113 are equal, or the lengths of the first comb teeth 113 at both ends of the first side wall 111 are greater than the length of the first comb teeth 113 in the middle of the first side wall 111, as long as the first contour surface 115 concave toward the center line of the brush rod 11 can be formed. When the mascara brush is taken out of the mascara bottle, the first comb teeth 113 corresponding to the concave area in the middle of the first contour surface 115 can carry a relatively appropriate amount of mascara. The gaps between the multiple first comb teeth 113 are fine and stable, thereby creating a more distinct and naturally long eyelash makeup effect. The first comb teeth 113 are also less likely to rub against other skin around the eyes and can better fit the roots of the eyelashes, making the eye makeup effect natural and more obvious.

[0038] The brush head 1 of the present application has a plurality of first comb teeth 113 that are away from the first side wall 111 and are constructed with a first contour surface 115 that is concave toward the center line of the brush rod 11, which is closer to the curvature of the eyelid. The first comb teeth 113 corresponding to the second concave area in the middle can penetrate deeper into the root of the eyelashes, especially the root of the eyelashes where the curvature of the eyelid is the largest. The first comb teeth 113 corresponding to the first area 115a and the third area 115c at both ends can more effectively cover and extend to the tip of the eyelashes, especially the eyelashes at the beginning and end of the eye. When applying eyelashes, due to the eye shape structure, the multiple first comb teeth 113 fit the eye shape better, so that the first comb teeth 113 can contact the eyelash roots at different positions more evenly, reducing the gaps or poking of the eyelids by the first comb teeth 113 at both ends, thereby improving comfort and fit. At the same time, when the brush head 1 is rotated to apply eyelashes, the arc-shaped first side wall 111 and the multiple first comb teeth 113 can bring out the natural curling curvature of the eyelashes according to the arc-shaped first comb teeth 113, thereby enhancing the three-dimensional sense of makeup and creating a slender and curled makeup effect.

[0039] Optionally, refer to Figure 6The first side wall 111 includes a first portion 111a, a second portion 111b and a third portion 111c that are connected. The distance between the first portion 111a and the center line of the brush rod 11 is greater than the distance between the second portion 111b and the center line of the brush rod 11. The distance between the third portion 111c and the center line of the brush rod 11 is greater than the distance between the second portion 111b and the center line of the brush rod 11.

[0040] The second portion 111b is located in the middle area of ​​the brush rod 11, and the first portion 111a and the third portion 111c are located at both ends of the brush rod 11. The first side wall 111 is constructed as a concave structure. When the brush is pulled out of the mascara bottle, the concave first side wall 111 can make the brush head 1 grab the mascara more evenly and guide the mascara to the second portion through capillary action, thereby reducing excessive accumulation of mascara at the roots of the first comb teeth 113, thereby achieving control of the amount of mascara dipped by the brush head 1. The appropriate amount of mascara has better combing properties when brushing the eyelashes, thereby achieving a natural and distinct effect.

[0041] Optionally, the groove depth between two adjacent first teeth 113 is smaller than the groove depth between two adjacent second teeth 114. The first teeth 113 with a smaller groove depth can carry a more appropriate amount of mascara to create a more distinct and naturally long eyelash makeup effect. At the same time, the first teeth 113 with a smaller groove depth have greater rigidity and can extend into the root of the eyelashes, ensuring that the mascara is applied properly and reducing mascara accumulation at the root of the eyelashes.

[0042] The second comb teeth 114 with a larger tooth groove depth can carry more mascara. At the same time, the second comb teeth 114 with a larger tooth groove depth can better contact longer eyelashes such as the end of the eye, and can cover the middle and end of the eyelashes, thereby creating a thicker and curled eyelash makeup effect.

[0043] The combination of the first comb teeth 113, which have a smaller groove depth, and the second comb teeth 114, which have a larger groove depth, can achieve a thicker root and a longer tail without having to change comb teeth or apply multiple applications, simplifying the makeup process. In other words, you can use the first comb teeth 113, the second comb teeth 114, or both, depending on your specific needs to create different makeup effects.

[0044] In an optional embodiment, the radius of curvature of the first contour surface 115 may be 140 mm to 158 mm. This radius of curvature is close to the physiological curvature of most people's eyelids, allowing the first contour surface 115 to closely follow the direction of eyelash growth. For example, when applying cream to the upper eyelashes, the first contour surface 115 can wrap around the eyelashes, ensuring that the cream is evenly covered from the root to the tail of the eyelashes, reducing missing spots caused by curvature mismatch.

[0045] In addition, the curvature radius of 140mm to 158mm is close to the arc trajectory of the natural swing of the hand. There is no need to deliberately adjust the wrist posture when using it, especially when brushing the tail of the eye or lower eyelashes, which can reduce arm fatigue and improve operation smoothness.

[0046] The radius of curvature of the first contour surface 115 cannot be too small. If the radius of curvature of the first contour surface 115 is too small, for example, if the radius of curvature of the first contour surface 115 is less than 140mm, the curvature of the first contour surface 115 will vary greatly, which may cause the first comb teeth 113 to exert excessive pulling force on the eyelashes, easily breaking the eyelashes or damaging the curling curve. If the radius of curvature of the first contour surface 115 is too large, for example, if it is greater than 158mm, the curvature surface will be too flat, and the first comb teeth 113 will not have sufficient support for the eyelashes during combing, making it difficult to maintain the curling effect, and mascara will easily accumulate at the roots of the eyelashes.

[0047] For example, the first contour surface 115 has a curvature radius of 155.5 mm. The arc surface with this curvature radius can separate each eyelash like a comb. The comb teeth exert uniform pressure on the eyelashes, and the mascara is scraped into a thin and uniform layer, reducing the adhesion of eyelashes caused by excessive local mascara.

[0048] The length of the first comb teeth 113 can be 0.25mm to 0.6mm. Short comb teeth have a smaller adsorption area, limiting the amount of mascara that can be applied at a time. Furthermore, the gaps between adjacent first comb teeth 113 are fine and stable, preventing eyelashes from sticking together due to excessive mascara. This creates a natural, distinct eyelash effect. For example, the length of the first comb teeth 113 is 0.3mm. Through the delicate manipulation and precise control of the short comb teeth, precise application of eyelashes is achieved.

[0049] Along the length direction X of the brush rod 11, the spacing between two adjacent first comb teeth 113 can be 0.2mm to 0.4mm. The spacing between two adjacent first comb teeth 113 is adapted to the diameter of the eyelashes, accurately capturing individual eyelashes and separating clusters of eyelashes into individual ones, achieving a distinct effect. For example, along the length direction X of the brush rod 11, the spacing between two adjacent first comb teeth 113 is 0.25mm.

[0050] Optionally, refer to Figures 2 to 6 The second side wall 112 includes a first sub-side wall 112a and a second sub-side wall 112b, the first sub-side wall 112a and the second sub-side wall 112b are adjacent to each other and are arranged at an angle; the second comb teeth 114 are arranged on the first sub-side wall 112a and the second sub-side wall 112b, and the second comb teeth 114 are an integrated structure.

[0051] Only one row of second comb teeth 114 is provided on the second side wall 112. The length of the second comb teeth 114 is greater than that of the first comb teeth 113. The tooth grooves between two adjacent second comb teeth 114 are deep, so that the second comb teeth 114 have better combing performance and can completely fit the eyelashes into the tooth grooves for combing, thereby creating a thick eyelash makeup effect and making the ends of the eyelashes longer.

[0052] Optionally, refer to Figure 1 , along the length direction X of the brush rod 11, the end of the plurality of second comb teeth 114 away from the second side wall 112 has a second outer profile 116, along the first direction Z ( Figure 1 The projection of the second outer contour 116 is parallel to the center line of the brush rod 11, and the first direction Z is perpendicular to the length direction X of the brush rod 11. In other words, the second outer contour 116 is constructed as a straight line. The straight second outer contour 116 can be brushed in parallel from the root to the tip of the eyelashes. Since the edge of the straight second outer contour 116 is clear and the mascara carried is even, a stable lateral coverage can be formed when brushing the eyelashes, which is suitable for uniform brushing over a large area. The cream applied to the middle section of the eyelashes can be evenly distributed, ensuring the thickness of the foundation and not easily crossing the boundary to stain the eyelids. At the same time, the second comb teeth 114 with a straight outer contour can lengthen the tail of the eyelashes to create a slender makeup effect.

[0053] Optionally, the length of the second comb teeth 114 can be 1mm to 1.35mm. At this length, the second comb teeth 114 can cover the tips of the eyelashes, visually lengthening the eyelashes. It can also prevent the comb teeth from carrying too much mascara, causing the eyelashes to clump or fly-legged, thereby achieving a natural and thick makeup effect. Moreover, the second comb teeth 114 of this length can be suitable for users with different eyelash lengths. For users with short eyelashes, the longer second comb teeth 114 can extend to the tip of the eyelashes, increasing the curl. For users with long eyelashes, this length can evenly wrap the entire eyelashes, avoiding insufficient application of mascara due to too short comb teeth.

[0054] Along the length X of the brush rod 11, the gap between two adjacent second comb teeth 114 is 0.4mm to 0.6mm. The size of the gap between two adjacent comb teeth determines the amount of mascara that the brush head 1 picks up. If the gap is too small, mascara will easily accumulate, while if the gap is too large, insufficient mascara will be picked up. The 0.4mm to 0.6mm gap between two adjacent second comb teeth 114 allows the comb teeth to pick up an appropriate amount of mascara, evenly distributing the mascara on the eyelashes during application, avoiding adhesion caused by too much mascara or incomplete coverage caused by too little mascara.

[0055] At the same time, the two comb teeth with appropriate spacing can comb the eyelashes one by one during application, and use the gaps between the comb teeth to separate the eyelashes, reduce clumping, and allow each eyelash to adhere to the cream independently, presenting a distinct effect.

[0056] For example, the length of the second comb teeth 114 may be 1.2 mm, and the gap between two adjacent first comb teeth 113 may be 0.5 mm.

[0057] Optionally, refer to Figure 6 The ends of the plurality of second comb teeth 114 away from the second sidewall 112 have a second outer profile 116. Along the first direction Z, the projection of the second outer profile 116 is recessed toward the centerline of the brush rod 11. The first direction Z is perpendicular to the lengthwise direction X of the brush rod 11. In other words, along the lengthwise direction X of the brush rod 11, the outer profiles of the ends of the plurality of second comb teeth 114 away from the second sidewall 112 are arcs that are recessed toward the centerline of the brush rod 11.

[0058] The second outer contour 116 of the end of the multiple second comb teeth 114 away from the second side wall 112 is designed to be concave in the middle, which can better fit the physiological curvature of the eyelid. The slightly raised top of the brush head 1 can be used to brush the detailed eyelashes at the beginning and end of the eye, making the overall makeup more refined and three-dimensional; and when the brush head 1 moves to apply the eyelashes, the comb teeth can evenly cover the eyelashes from the root to the tip, especially for curved areas such as the end of the eye that are easy to miss, reducing white space or uneven application.

[0059] The radius of curvature of the second outer contour 116 can be 140 mm to 158 mm. This radius of curvature is close to the physiological curvature of most people's eyelids, allowing the second outer contour 116 to closely follow the direction of eyelash growth. For example, when applying cream to the upper eyelashes, the second outer contour 116 can wrap around the eyelashes, ensuring that the cream is evenly covered from the root to the tail of the eyelashes, avoiding missing spots due to curvature mismatch.

[0060] In addition, the curvature radius of 140mm to 158mm is close to the arc trajectory of the natural swing of the hand. There is no need to deliberately adjust the wrist posture when using it, especially when brushing the tail of the eye or lower eyelashes, which can reduce arm fatigue and improve operation smoothness.

[0061] The radius of curvature of the second outer contour 116 should not be too small. If the radius of curvature of the second outer contour 116 is too small, for example, if the radius of curvature of the second outer contour 116 is less than 140mm, the curvature of the second outer contour 116 will vary greatly, which may cause the second comb teeth 114 to exert excessive pulling force on the eyelashes, easily breaking the eyelashes or destroying the curling curve. If the radius of curvature of the second outer contour 116 is too large, for example, if it is greater than 158mm, the curved surface will be too flat, and the second comb teeth 114 will not have sufficient support for the eyelashes during combing, making it difficult to maintain the curling effect, and the cream will easily accumulate at the roots of the eyelashes.

[0062] Exemplarily, the curvature radius of the second outer contour 116 can be 155.5 mm. The arc surface of this curvature radius can separate each eyelash like a comb. The comb teeth exert uniform pressure on the eyelashes, and the cream is "scraped" into a thin and uniform layer, reducing the adhesion of eyelashes caused by excessive local cream.

[0063] The length of the second comb teeth 114 can be 0.8mm to 1.35mm, so that the "liquid reservoir" formed by the gap between the comb teeth has a larger volume, which can be dipped into more mascara, suitable for users who pursue a thicker effect. At the same time, the effective contact length of the second comb teeth 114 is about 0.8mm to 1.35mm, which can cover longer eyelashes at one time, reducing the number of repeated application and improving operating efficiency.

[0064] In one embodiment, reference Figure 7 The ends of the plurality of second comb teeth 114 distal from the second sidewall 112 have a second outer profile 116. Along a first direction Z, the projection of the second outer profile 116 bulges away from the centerline of the brush rod 11. The first direction Z is perpendicular to the lengthwise direction X of the brush rod 11. Along the lengthwise direction X of the brush rod 11, the outer profiles of the ends of the plurality of second comb teeth 114 distal from the second sidewall 112 are arcs that bulge away from the centerline of the brush rod 11. The second outer profiles 116 of the plurality of second comb teeth 114 are configured as outwardly convex arcs. This allows the second comb teeth 114 to better conform to the natural curvature of eyelashes at the beginning or end of the eye when applying mascara, allowing the outer comb teeth to reach the corners of the back of the eye, reducing missed areas. The middle portions of the multiple second comb teeth 114 form a convex structure, which reduces the chance of the second comb teeth 114 rubbing against the eyelids when applying mascara. Furthermore, the convex second outer contour 116 creates a deeper gap between adjacent second comb teeth 114, allowing for more mascara to be carried and providing better combing properties, enabling the creation of thicker, longer, and curled lashes. Furthermore, the second comb teeth 114 remove excess mascara when combing lashes, thereby reducing clumping. Furthermore, the second comb teeth 114 corresponding to the convex portion can also be used to partially lengthen and thicken lashes, creating different makeup styles.

[0065] Optionally, refer to Figure 8 and Figure 9 The second side wall 112 includes a first sub-side wall 112a and a second sub-side wall 112b, and the first sub-side wall 112a is adjacent to the second sub-side wall 112b and is arranged at an angle; the second comb teeth 114 include a first sub-comb tooth 114a and a second sub-comb tooth 114b, and the first sub-comb tooth 114a is arranged on the first sub-side wall 112a, and the second sub-comb tooth 114b is arranged on the second sub-side wall 112b, and the first sub-comb tooth 114a and the second sub-comb tooth 114b are split structures.

[0066] Along the circumference of the brush rod 11, there is a gap between the first sub-comb teeth 114a and the second sub-comb teeth 114b, and the gap can carry mascara. When using the first sub-comb teeth 114a and the second sub-comb teeth 114b to comb eyelashes, the eyelashes stuck in the gap between the first sub-comb teeth 114a and the second sub-comb teeth 114b can be evenly dipped into the mascara in the gap, so that the brushed eyelashes are more uniform and thicker. Exemplarily, the width of the end of the first sub-comb tooth 114a connected to the first sub-side wall 112a along the circumferential direction of the brush rod 11 is greater than the width of the free end of the first sub-comb tooth 114a, and the width of the end of the second sub-comb tooth 114b connected to the second sub-side wall 112b along the circumferential direction of the brush rod 11 is greater than the width of the free end of the second sub-comb tooth 114b. Therefore, from the root of the comb teeth to the free end, the gap between the first sub-comb tooth 114a and the second sub-comb tooth 114b along the circumferential direction of the brush rod 11 gradually increases. The gap can carry more mascara, so that the eyelashes stuck in the gap can be dipped in more mascara, making the eyelashes more uniform and thicker.

[0067] Optionally, refer to Figure 8 and Figure 9 Along the length direction X of the brush rod 11, a plurality of first sub-comb teeth 114a and a plurality of second sub-comb teeth 114b are staggered. That is, the arrangement position of the second sub-comb teeth 114b corresponds to the gap between two adjacent first sub-comb teeth 114a. The staggered arrangement of the plurality of first sub-comb teeth 114a and the plurality of second sub-comb teeth 114b can better control the depth of the gap between two adjacent comb teeth and the width of the gap along the length direction of the brush rod 11. A deeper and wider gap can carry more mascara. When applying mascara, more mascara can be applied to the roots of the eyelashes. The width between two adjacent comb teeth along the circumference of the brush rod 11 is smaller. Along the circumference of the brush rod 11, the length of the gap between two adjacent comb teeth is relatively small, and the amount of mascara carried is also relatively small, thereby reducing the damage to the overall makeup effect caused by excessive mascara applied to the ends of the eyelashes.

[0068] In addition, multiple first sub-comb teeth 114a and multiple second sub-comb teeth 114b are arranged in an interlaced manner, and two adjacent first sub-comb teeth 114a along the length direction of the brush rod 11 and the corresponding second sub-comb teeth 114b between the two first sub-comb teeth 114a form a cavity area. When the brush head 1 is used to apply mascara, the adjacent two first sub-comb teeth 114a and the corresponding second sub-comb teeth 114b comb the roots of multiple eyelashes, and the tips of multiple eyelashes will fall into the strong area between the same two adjacent comb teeth, so that the multiple eyelashes are aggregated into a cluster at the end of the eyelashes, thereby achieving a clustered eyelash makeup effect.

[0069] Optionally, refer to Figure 10Along the length direction X of the brush rod 11, the ends of the plurality of second comb teeth 114 away from the second side wall 112 have a second outer profile 116. Along the first direction Z, the projection of the second outer profile 116 is parallel to the centerline of the brush rod 11, and the first direction Z is perpendicular to the length direction X of the brush rod 11. The ends of the plurality of second comb teeth 114 away from the second side wall 112 form a second outer profile 116, and the second outer profile 116 is configured as a plane. In other words, the outer profile of the end of the first sub-comb tooth 114a away from the second side wall 112 and the outer profile of the end of the second sub-comb tooth 114b away from the second side wall 112 together form the second outer profile 116, and the second outer profile 116 is configured as a plane. The projection of the second outer profile 116 along the first direction Z is a straight line and is parallel to the centerline of the brush rod 11. The multiple second comb teeth 114 with a flat outer contour carry mascara evenly, which can form a stable horizontal coverage when brushing the eyelashes. It is suitable for uniform brushing over a large area and can evenly distribute the mascara in the middle section of the eyelashes to ensure the basic density.

[0070] Optionally, refer to Figure 11 The ends of the multiple second comb teeth 114 facing away from the second sidewall 112 have a second outer profile 116. Along a first direction Z, the projection of the second outer profile 116 is concave toward the centerline of the brush rod 11. The first direction Z is perpendicular to the lengthwise direction X of the brush rod 11. The outer profile of the first sub-comb teeth 114a facing away from the second sidewall 112 is an inwardly concave arc. The outer profile of the second sub-comb teeth 114b facing away from the second sidewall 112 is also an inwardly concave arc. Together, these two forms the second outer profile 116, which is constructed as an arc surface concave toward the centerline of the brush rod 11. The projection of the second outer profile 116 along the first direction Z is an inwardly concave arc. This inwardly concave arc allows the second comb teeth 114 to focus their effect on the root of the eyelashes. The concave arc wraps the eyelashes, making the cream at the root of the eyelashes thicker. The comb teeth on both sides also help separate the eyelashes, creating a "clearly defined" and thickened makeup effect.

[0071] At the same time, the curvature of the second outer contour constructed by the multiple second comb teeth 114 fits the eye curve better, the length of the second comb teeth 114 at both ends of the brush head 1 is greater than the length of the second comb teeth 114 in the middle of the brush head 1, and the tooth groove depth between the second comb teeth 114 at both ends of the brush head 1 is greater than the tooth groove depth between the second comb teeth 114 in the middle of the brush head 1. More mascara is carried between the second comb teeth 114 at both ends of the brush head 1, and the second comb teeth 114 at both ends of the brush head 1 can be used to brush the eyelashes at the beginning and end of the eyes, and can cover the middle and end of the eyelashes, thereby creating a thicker and curled eyelash makeup effect; the mascara carried between the second comb teeth 114 in the middle of the brush head 1 is relatively less, creating a more distinct and naturally long eyelash makeup effect, and at the same time, the smaller second comb teeth 114 can extend into the root of the eyelashes, ensuring that the mascara can be applied in place and reducing the accumulation of mascara at the root of the eyelashes.

[0072] For example, the radius of curvature of the second outer contour 116 can be 140 mm to 158 mm. This approximates the physiological curvature of most people's eyelids, allowing the second comb teeth 114 to closely follow the direction of eyelash growth. For example, when applying cream to the upper eyelashes, the second comb teeth 114 can wrap around the eyelashes, evenly covering the cream from the root to the tail of the eyelashes, reducing missing spots caused by the mismatched curvature.

[0073] The spacing between two adjacent second comb teeth 114 along the length direction X of the brush rod 11 is 0.25 mm. When the brush head 1 passes through the eyelashes, the 0.25 mm gap can accurately catch a single eyelash between two adjacent comb teeth, preventing two eyelashes from entering the gap at the same time and causing adhesion.

[0074] Optionally, refer to Figure 12 The ends of the multiple second comb teeth 114 away from the second sidewall 112 have a second outer profile 116. Along a first direction Z, the projection of the second outer profile 116 bulges outward from the centerline of the brush rod 11. The first direction Z is perpendicular to the length direction X of the brush rod 11. The outer profile of the end of the first sub-comb teeth 114a away from the second sidewall 112 is an arc bulging outward from the centerline of the brush rod 11. The outer profile of the end of the second sub-comb teeth 114b away from the second sidewall 112 is an arc bulging outward from the centerline of the brush rod 11. Together, the two form the second outer profile 116. The second outer profile 116 is constructed as an arc bulging outward from the centerline of the brush rod 11. The projection of the second outer profile 116 along the first direction Z is an outward convex arc. When using the second comb teeth 114 to apply to eyelashes, if the second outer profile 116 is constructed as an outward convex arc, the second comb teeth 114 can better fit the natural curvature of the eyelashes at the end of the eye, allowing the outer comb teeth to reach the corners of the eye and reduce missed lashes.

[0075] The middle portions of the multiple second comb teeth 114 form a convex structure, which reduces the chance of the second comb teeth 114 rubbing against the eyelids when applying mascara. The convex second outer contour 116 also creates a deeper gap between adjacent second comb teeth 114, allowing for more mascara to be carried and providing better combing properties, enabling the creation of thicker, longer, and curled lashes. Furthermore, the second comb teeth 114 remove excess mascara from the lashes during combing, thereby reducing clumping. Furthermore, the second comb teeth 114 corresponding to the convex portion can also be used to partially lengthen and thicken lashes, creating different makeup styles.

[0076] The curvature radius of the second outer contour 116 may be 47.5 mm. The highest point of the convexity corresponds to the eyelashes in the middle area of ​​the eyelid. The convex arc segment with a curvature radius of 47.5 mm can apply more mascara to the longer eyelashes in the middle area of ​​the eyelid, thereby enhancing the length and volume of the makeup.

[0077] The length of the second comb teeth 114 can be 0.3 mm. The second comb teeth 114 can be parallel to the edge of the eyelid to adhere the mascara to the root of the eyelashes, avoiding the long comb teeth from rubbing against the skin of the lower eyelid due to excessive inclination angle, or preventing the second comb teeth 114 from being too long, resulting in too much mascara being carried between two adjacent comb teeth, causing adhesion to the root of the eyelashes.

[0078] In an optional embodiment, along the length direction X of the brush rod 11, the spacing between two adjacent first comb teeth 113 is smaller than the spacing between adjacent first sub-comb teeth 114a and second sub-comb teeth 114b. The larger spacing between the second comb teeth 114 allows them to carry more mascara, creating a thicker eyelash effect. The smaller spacing between the first comb teeth 113 allows them to carry less mascara, making it easier to create a naturally long, distinct eyelash effect.

[0079] Optionally, at least one of the first sub-sidewall 112a and the second sub-sidewall 112b is flat. The flat sidewall provides stable support for the second comb teeth 114, reduces bending of the second comb teeth 114, and improves the overall rigidity of the brush head 1. When applying mascara, the second comb teeth 114 can more effectively push or press the mascara, increasing the force exerted by the second comb teeth 114 on the eyelashes, achieving more precise control and improving makeup application efficiency.

[0080] In an alternative embodiment, reference Figure 5 and Figure 9, the first sub-side wall 112a is connected to the second sub-side wall 112b, and the connection between the first sub-side wall 112a and the second sub-side wall 112b protrudes toward the center line of the brush rod 11, that is, the distance between the side of the first sub-side wall 112a close to the second sub-side wall 112b and the center line of the brush rod 11 is greater than the distance between the side of the first sub-side wall 112a away from the second sub-side wall 112b and the center line of the brush rod 11, the first sub-side wall 112a is formed into a slope, and the side of the first sub-side wall 112a away from the second sub-side wall 112b is larger than the side of the first sub-side wall 112a away from the second sub-side wall 112b. More mascara is stored on the side of first sub-sidewall 112a closer to second sub-sidewall 112b; the distance between the side of second sub-sidewall 112b closer to first sub-sidewall 112a and the centerline of brush rod 11 is greater than the distance between the side of second sub-sidewall 112b farther from first sub-sidewall 112a and the centerline of brush rod 11. Second sub-sidewall 112b is formed into a slope, and the side of second sub-sidewall 112b farther from first sub-sidewall 112a stores more mascara than the side of second sub-sidewall 112b closer to first sub-sidewall 112a. Exemplarily, the angle between first sub-sidewall 112a and second sub-sidewall 112b is an obtuse angle, such as 140°. The connection between the first sub-side wall 112a and the second sub-side wall 112b forms an outwardly protruding edge. When using the second comb teeth 114a to apply mascara, the edge at the connection between the first sub-side wall 112a and the second sub-side wall 112b can scrape off excess mascara, thereby reducing the risk of eyelashes sticking together or forming fly legs due to excessive application of mascara.

[0081] Optionally, the second comb tooth 114 includes a first top end and a first bottom end that are relatively arranged, the first bottom end is connected to the second side wall 112, and the cross-sectional area of ​​the second comb tooth 114 gradually decreases from the first bottom end to the first top end, wherein the first top end is the free end of the second comb tooth 114.

[0082] The second comb teeth 114 are constructed in an approximately triangular shape, with a first top end and a first bottom end arranged opposite to each other. The first bottom end of the second comb teeth 114 connected to the second side wall 112 has a larger cross-sectional area, which can provide stable support and can carry more mascara. The first top end of the second comb teeth 114 has a smaller cross-sectional area and carries less mascara. The first top end of the second comb teeth 114 can extend into the gap at the root of the eyelashes, which can achieve precise makeup of a single eyelash and reduce clumping at the root of the eyelashes. The first bottom end carrying more mascara can lengthen the tail of the eyelashes.

[0083] Along the length direction X of the brush handle 11, the outer contour of the projection of the second comb teeth 114 includes a first sub-contour line and a second sub-contour line, both of which are configured as arcs. In other words, the second comb teeth 114 have an arc-shaped outer contour. When applying mascara, the arc-shaped outer contour can better support the eyelashes, allowing them to be better loaded with mascara, thereby creating a thick and curled effect.

[0084] Exemplarily, from the first bottom end to the first top end, the cross-sectional area of ​​the first sub-comb tooth 114a gradually decreases, and the cross-sectional area of ​​the second sub-comb tooth 114b gradually decreases. The first sub-comb tooth 114a and the second sub-comb tooth 114b both have the arc-shaped outer contour of the above-mentioned second comb tooth 114. The first sub-comb tooth 114a and the second sub-comb tooth 114b have the same effect as the second comb tooth 114, which will not be repeated here.

[0085] In one embodiment, the first comb teeth 113 have rounded corners on the side away from the first sidewall 111, and the second comb teeth 114 have rounded corners on the side away from the second sidewall 112, to reduce damage to the skin or eyelashes when they come into contact with the skin. The first comb teeth 113 have rounded corners at the end connected to the first sidewall 111, and the second comb teeth 114 have rounded corners at the end connected to the second sidewall 112, to facilitate processing.

[0086] Optionally, refer to Figure 13 The first contour surface 115 also includes a fourth area 115d and a fifth area 115e. Along the length direction X of the brush rod 11, the fourth area 115d is arranged on the side of the first area 115a away from the second area 115b, and the fifth area 115e is arranged on the side of the third area 115c away from the second area 115b. The fourth area 115d and the fifth area 115e are both constructed as arc surfaces convex toward the center line away from the brush rod 11.

[0087] The first contour surface 115 has outwardly protruding portions at both ends and an inwardly recessed portion in the middle. The first sub-comb teeth 114a corresponding to the outwardly protruding fourth and fifth regions 115d and 115e are longer, allowing them to absorb more mascara. This makes them suitable for applying to areas like the roots of eyelashes where more mascara is needed to increase volume, helping to create a fuller, fuller eyelash effect. Furthermore, the outwardly protruding portions have a certain curvature and curve to better conform to the curvature of the eye, especially to areas such as the inner and outer corners of the eyes where mascara is more difficult to apply. The outwardly protruding portions allow for easy access to eyelashes at the beginning and end of the eyes, which are more difficult to apply mascara to. The first comb teeth 113 corresponding to the inwardly recessed portions are shorter, allowing for precise control of the amount of mascara applied, preventing lashes from clumping due to excessive application, and ensuring distinct, distinct eyelashes.

[0088] Optionally, refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 9 The first side wall 111 and the second side wall 112 are disposed on opposite sides of the brush rod 11 along a second direction Y, which is perpendicular to the length direction X of the brush rod 11. The first side wall 111 and the second side wall 112 are spatially independent of each other. During use, the plurality of first comb teeth 113 and the plurality of second comb teeth 114 do not interfere with each other. The user can choose to use the first comb teeth 113 or the second comb teeth 114 according to their preferences and different makeup needs.

[0089] Optionally, refer to Figure 2 、 Figure 5 and Figure 9 The brush holder 11 further includes a third sidewall 117 and a fourth sidewall 118, which are arranged opposite each other along a first direction Z. The third sidewall 117 is connected to the first sidewall 111 and the second sidewall 112, and the fourth sidewall 118 is connected to the first sidewall 111 and the second sidewall 112. The spacing between the third sidewall 117 and the fourth sidewall 118 along the first direction Z first decreases and then increases. The second direction Y, the first direction Z, and the longitudinal direction X of the brush holder 11 are perpendicular to each other. The third sidewall 117 and the fourth sidewall 118 are also concave toward the centerline of the brush holder 11, which can reduce interference of the third sidewall 117 and the fourth sidewall 118 with the eyelashes when applying mascara.

[0090] From the first end 11a to the second end 11b, the ends of the first comb teeth 113 closest to the third side wall 117 and the ends of the first comb teeth 113 closest to the fourth side wall 118 first decrease in size and then increase in size along the first direction Z. In other words, the third side wall 117 and the fourth side wall 118 are also concave toward the centerline of the brush rod 11, which reduces interference of the third side wall 117 and the fourth side wall 118 with eyelashes when applying mascara.

[0091] Optionally, along the first direction Z, the minimum distance between the third side wall 117 and the fourth side wall 118 is greater than the distance between the first side wall 111 and the second side wall 112. The minimum distance between the third side wall 117 and the fourth side wall 118 can be understood as the minimum distance between the projection of the third side wall 117 along the length direction of the brush rod 11 and the projection of the fourth side wall 118 along the length direction of the brush rod 11; the minimum distance between the first side wall 111 and the second side wall 112 can be understood as the minimum distance between the projection of the first side wall 111 along the length direction of the brush rod 11 and the projection of the second side wall 112 along the length direction of the brush rod 11. Since the distance between the third side wall 117 and the fourth side wall 118 is relatively large, it can be understood that the dimension of the first side wall 111 along the first direction Z is larger. The highest point of the outward protrusion of the first comb teeth 113 has a relatively gentle slope toward both sides, and the arc is longer. When applying mascara, the first comb teeth 113 with a longer arc can well support the tail of the eyelashes, making the tail of the eyelashes easier to apply, thereby making the entire eyelash makeup effect longer and curler.

[0092] For example, the third side wall 117 and the fourth side wall 118 may be configured as planes.

[0093] Optionally, the brush rod 11, the plurality of first comb teeth 113, and the plurality of second comb teeth 114 are configured as a flat structure. The first comb teeth 113 and the second comb teeth 114 are respectively located on opposite sides of the brush rod 11, so that the first comb teeth 113 and the second comb teeth 114 are spatially independent of each other. The brush rod 11, the plurality of first comb teeth 113, and the plurality of second comb teeth 114 are configured as a flat structure along the second direction Y. When in use, the plurality of first comb teeth 113 and the plurality of second comb teeth 114 are spaced relatively large apart from each other and do not interfere with each other.

[0094] Optionally, the brush rod 11, the plurality of first comb teeth 113, and the plurality of second comb teeth 114 are all constructed as an integrally formed stainless steel part. The stainless steel material has a smooth surface, is not easy to absorb dirt and bacteria, and is easy to clean, thereby improving eye hygiene.

[0095] Optionally, refer to Figure 14 Along the length direction X of the brush rod 1, the second side wall 112 includes a first middle area 121 and a first edge area 122 and a second edge area 123 located on both sides of the first middle area 121. The distance between the first middle area 121 and the center line of the brush rod 1 is greater than the distance between the first edge area 122 and the center line of the brush rod 1, and the distance between the first middle area 121 and the center line of the brush rod 1 is greater than the distance between the second edge area 123 and the center line of the brush rod 1.

[0096] Along the length direction X of the brush rod 1, the second sidewall 112 includes a first edge region 122, a first intermediate region 121, and a second edge region 123, which are connected in sequence. The distance between the first intermediate region 121 and the centerline of the brush rod 1 is greater than the distance between the first edge region 122 and the centerline of the brush rod 1. The distance between the first intermediate region 121 and the centerline of the brush rod 1 is also greater than the distance between the second edge region 123 and the centerline of the brush rod 1. In other words, along the length direction X of the brush rod 1, the distance between the second sidewall 112 and the centerline of the brush rod 1 first increases and then decreases from the first edge region 122 to the second edge region 123. In other words, the second sidewall 112 of the brush rod 1 bulges outward to form a curved surface.

[0097] The second sidewall 112 is constructed as an outwardly convex curved surface, allowing the first middle region 121 of the brush head 1 to fit the curvature of the middle part of the eye when applying mascara, while the first and second edge regions 122, 123 on either side can adapt to relatively flat or less curved areas such as the corners of the eyes. This overall increases the contact area between the brush head 1 and the eyelashes, improving application efficiency. For example, when applying mascara to the upper eyelashes, the first middle region 121 can closely fit the curvature above the eyeball, ensuring that mascara is evenly applied to the eyelashes, while the first and second edge regions 122, 123 can apply mascara to the eyelashes at the beginning and end of the eye.

[0098] In addition, the second side wall 112 of the brush handle 1 protrudes outward, so that when the second comb teeth 114 contact the eyelashes, the second side wall 112 can apply force at an angle that is more consistent with the natural growth direction of the eyelashes. The second side wall 112 of the brush handle 1 also provides an outward and upward support force to the eyelashes, which can better pull the eyelashes upward and thus improve the curl of the eyelashes. The first side wall 111 of the brush handle 1 is constructed as a flat surface to better assist the comb teeth on the second side wall 112 in applying mascara, thereby achieving a better makeup effect.

[0099] Optionally, refer to Figure 15 The second side wall 112 is constructed in an arc shape; along the length direction X of the brush rod 1, the second side wall 112 includes a second middle area 124 and a third edge area 125 and a fourth edge area 126 located on both sides of the second middle area 124. The distance between the second middle area 124 and the center line of the brush rod 1 is smaller than the distance between the third edge area 125 and the center line of the brush rod 1, and the distance between the second middle area 124 and the center line of the brush rod 1 is smaller than the distance between the fourth edge area 126 and the center line of the brush rod 1.

[0100] Along the length direction X of the brush rod 1, the second sidewall 112 includes a third edge region 125, a second intermediate region 124, and a fourth edge region 126, which are sequentially connected. The distance between the second intermediate region 124 and the centerline of the brush rod 1 is smaller than the distance between the third edge region 125 and the centerline of the brush rod 1. The distance between the second intermediate region 124 and the centerline of the brush rod 1 is also smaller than the distance between the fourth edge region 126 and the centerline of the brush rod 1. In other words, along the length direction X of the brush rod 1, from the third edge region 125 to the fourth edge region 126, the distance between the second sidewall 112 and the centerline of the brush rod 1 first decreases and then increases. In other words, the second sidewall 112 of the brush rod 1 is concave inward to form a curved surface.

[0101] The second sidewall 112 is concave, allowing for temporary storage of mascara, reducing the need for frequent dipping. This is especially true when the brush is withdrawn, as the concave area absorbs more mascara. Furthermore, the concave area guides mascara toward the base of the teeth, reducing the chance of excess buildup at the tips. This allows for more even application, minimizing clumping and "fly-leg" effects. The concave design of the second sidewall 112 enhances the grip of the teeth around the eyelashes, creating a long-lasting, curled look.

[0102] Second, reference Figure 16 and Figure 17 The present invention also provides an eyelash brush comprising a brush handle 2 and the brush head 1 described in any of the above embodiments. The brush handle 2 is connected to one end of the brush rod 11 along the length direction. The brush handle 2 provides a handhold for the operator to control the brush head 1 to fit the eyelashes and apply the brush evenly, thereby achieving a curled, thick, and natural eyelash makeup effect.

[0103] The brush head 1 and the brush handle 2 can be integrally formed. This reduces the number of molds required, greatly simplifies the production process, improves production efficiency, and reduces costs. Furthermore, the integral formation of the brush head 1 and the brush handle 2 can reduce the gaps between the components, making the brush head 1 easier to clean and less likely to harbor dirt and reduce bacterial growth.

[0104] Optionally, refer to Figure 17 The brush head 1 and the brush handle 2 are set at an angle, which can automatically compensate for the angle of the wrist, so that the wrist does not need to be excessively bent or lifted when the brush head 1 contacts the eyelashes, reducing the user's fatigue, and the brush head is more likely to be parallel to the curvature of the eyelid, so that the entire row of comb teeth can fully contact the root to the tip of the eyelashes at the same time, improving the wrapping efficiency and application uniformity. The angle of the brush head 1 and the brush handle 2 can be freely selected according to the needs of the user and is not limited here. For example, the angle between the brush head 1 and the brush handle 2 is 3-12 degrees, which is more in line with the user's holding habit, allowing the user to use a more comfortable holding posture to brush the corners of the eyes and other locations.

[0105] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.
