Description

TECHNICAL FIELD

[0001] The present application relates to the field of cosmetic technology, in particular to a brush head for a mascara brush and a mascara brush. BACKGROUND

[0002] The mascara brush is one of the important tools for eye makeup. The mascara brush is used to dip mascara to make up, curl and shape, and lengthen the eyelashes, so that the eyelashes are dense, distinct, and natural and long.

[0003] At present, the shape of the brush head of some mascara brushes does not fit the eye type, for example, when some straight cylindrical brush heads are used to apply mascara to the eye head and the eye tail, it is difficult to accurately cover and evenly brush, so that the eyelashes in these parts cannot be fully modified, and the makeup effect is not natural and the eyelashes are not long enough.

[0053] In a first aspect, with reference to Figures 1 to 13The 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, a peripheral surface of the brush rod 11 comprising a first side wall 111 and a second side wall 112, along a length direction X of the brush rod 11, an outer contour of a cross section of the first side wall 111 is arc-shaped and protrudes away from a 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, a projection of the first comb tooth 113 has a first edge, the first edge is connected with the first side wall 111, and the first edge is arc-shaped and protrudes away from the center line of the brush rod 11, the plurality of second comb teeth 114 are arranged on the second side wall 112, along the length direction X of the brush rod 11, the 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, in a direction from the first end 11a to the second end 11b, one end of the plurality of first comb teeth 113 away from the first side wall 111 jointly forms a first profile surface 115, the first profile surface 115 comprises a first region 115a, a second region 115b and a third region 115c connected with each other, a spacing between the first region 115a and the center line of the brush rod 11 is greater than a spacing between the second region 115b and the center line of the brush rod 11, and a spacing between the third region 115c and the center line of the brush rod 11 is greater than the spacing between the second region 115b and the center line of the brush rod 11.

[0054] Reference Figure 1 And Figure 2 The first side wall 111 is arranged to be arc-shaped and protrude outwardly away from the center line of the brush rod 11, the first comb tooth 113 is arranged on the first side wall 111, the projection of the first comb tooth 113 comprises a first edge and a second edge, the first edge and the second edge are oppositely arranged, the first edge is arranged on the first side wall 111, and the second edge is away from the first side wall 111 compared with the first edge, and the first edge and the second edge can both be arc-shaped, that is, the first comb tooth 113 is arranged in an arc-shaped structure similar to a fan surface, the arc-shaped structure can make the first comb tooth 113 better adapt to the natural curvature of the eyelashes, can closely fit each part from the root to the tip of the eyelashes, is especially suitable for outlining the details of the tail of the eye or the lower eyelashes, reduces a blind area of application, and makes the mascara evenly cover each eyelash. And the gap between the plurality of first comb teeth 113 in the arc-shaped structure can scrape an appropriate amount of mascara, when the plurality of first comb teeth 113 comb the eyelashes, from the root of the eyelashes to the tail of the eyelashes, the brush head 1 is rotated, so that the mascara in the gap between the plurality of first comb teeth 113 can be evenly covered on the eyelashes, and a natural and clear makeup effect is achieved.

[0055] It should be noted that the second side can also be formed in other approximate arc shapes, such as an approximate arc polygon, or an irregular edge, as long as the first comb teeth 113 can be configured as a flat structure similar to a fan.

[0056] Exemplarily, the setting direction of the first comb teeth 113 can be perpendicular to the length direction X of the brush rod 11, that is, the plane where the first comb teeth 113 are located is perpendicular to the length direction X of the brush rod 11; or the setting direction of the first comb teeth 113 is inclined relative to the length direction X of the brush rod 11; or the first comb teeth 113 are spirally inclined and arranged on the first side wall 111. When the first comb teeth 113 are spirally inclined and arranged on the first side wall 111, when applying mascara, the brush head moves while curling the eyelashes from the roots to the tips of the eyelashes, achieving the effect of lengthening and curling the eyelashes.

[0057] Along the length direction X of the brush rod 11, the distance between the first region 115a and the third region 115c and the center line of the brush rod 11 is greater than the distance between the second region 115b and the center line of the brush rod 11, that is, the first profile surface 115 is configured as a concave arc surface towards the center line of the brush rod 11. Specifically, along the length direction X of the brush rod 11, the length of the first comb teeth 113 at both ends of the first side wall 111 is 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 distance between the portion of the first side wall 111 at both ends of the brush rod 11 and the center line of the brush rod 11 is greater than the distance between the portion of the first side wall 111 in the middle of the brush rod 11 and the center line of the brush rod 11, while 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 lengths of the first comb teeth 113 in the middle of the first side wall 111, as long as the first profile surface 115 can be formed as a concave arc surface towards the center line of the brush rod 11. When the mascara brush is taken out of the mascara bottle, the first comb teeth 113 corresponding to the concave region in the middle of the first profile surface 115 can carry a suitable amount of mascara, the gaps between the plurality of first comb teeth 113 are fine and stable, thereby creating a more natural and lengthened eyelash makeup effect, the first comb teeth 113 are less likely to touch other skin around the eyes, and the eyelash makeup can be more natural and obvious.

[0058] The plurality of first comb teeth 113 of the brush head 1 in the present application are configured to form a first profile surface 115 recessed towards the center line of the brush rod 11 away from one end of the first side wall 111, which is closer to the curvature of the eyelid. The first comb teeth 113 corresponding to the second region in the middle are capable of reaching deeper into the root of the eyelashes, especially the root of the eyelashes with the largest curvature in the middle of the eyelid. The first comb teeth 113 corresponding to the first region 115a and the third region 115c at both ends are capable of more effectively covering and extending to the tips of the eyelashes, especially the eyelashes at the corners of the eyes and the tail of the eye. When applying the eyelashes, the plurality of first comb teeth 113 are more in line with the eye shape, allowing the first comb teeth 113 to more evenly contact the roots of the eyelashes at different positions, reducing the possibility of gaps or poking the eyelid by the first comb teeth 113 at both ends, and improving comfort and fit. At the same time, the arc-shaped first side wall 111 and the plurality of first comb teeth 113 can bring out the natural curling curvature of the eyelashes when rotating the brush head 1 to apply the eyelashes, enhancing the three-dimensional effect of the makeup, and creating a long and curled makeup effect.

[0059] Optionally, referring to Figure 6 , the first side wall 111 includes a first portion 111a, a second portion 111b, and a third portion 111c connected together. 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.

[0060] The second portion 111b is located in the middle region 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 configured as a concave structure. When the brush head 1 is pulled out of the mascara bottle, the concave first side wall 111 can more evenly pick up the mascara and guide it to the second portion through capillary action, reducing the excessive accumulation of mascara at the roots of the first comb teeth 113, thereby controlling the amount of mascara picked up by the brush head 1. An appropriate amount of mascara has good combing properties when brushing the eyelashes, thereby achieving a natural and distinct root effect.

[0061] Optionally, the depth of the tooth groove between two adjacent first comb teeth 113 is less than the depth of the tooth groove between two adjacent second comb teeth 114. The first comb teeth 113 with smaller tooth groove depth can carry an appropriate amount of mascara to create a more natural and distinct root long eyelash makeup effect. At the same time, the first comb teeth 113 with smaller tooth groove depth have stronger rigidity and 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.

[0062] The second comb tooth 114 with a larger tooth groove depth can carry more mascara, and the second comb tooth 114 with a larger tooth groove depth can better contact the longer eyelashes at the tail of the eye, cover the middle and end of the eyelashes, and thus create a more dense and curled eyelash makeup effect.

[0063] The first comb tooth 113 with a smaller tooth groove depth and the second comb tooth 114 with a larger tooth groove depth are used in combination, which can achieve the effects of dense roots and long tails without the need to replace the comb teeth or apply multiple times, thereby simplifying the makeup steps. That is, the first comb tooth 113 or the second comb tooth 114 or both the first comb tooth 113 and the second comb tooth 114 can be used according to specific needs to create different makeup effects.

[0064] In an optional embodiment, the radius of curvature of the first profile surface 115 can be 140 mm to 158 mm. The radius of curvature of 140 mm to 158 mm is close to the physiological arc of most people's eyelids, so that the first profile surface 115 can closely fit the growth direction of the eyelashes. When brushing the upper eyelashes, the first profile surface 115 can wrap the eyelashes, so that the eyelashes from the root to the tail can be evenly covered with mascara, thereby reducing missed application due to mismatched arc.

[0065] In addition, the radius of curvature of 140 mm to 158 mm is close to the circular arc trajectory of natural hand swing, so that there is no need to deliberately adjust the wrist posture during use, especially when brushing the tail of the eye or the lower eyelashes, which can reduce arm fatigue and improve operation fluency.

[0066] The radius of curvature of the first profile surface 115 cannot be too small. If the radius of curvature of the first profile surface 115 is too small, such as less than 140 mm, the first profile surface 115 has too large an arc change, which can cause the first comb tooth 113 to have too large a pulling force on the eyelashes, easily breaking the eyelashes or damaging the curled arc. If the radius of curvature of the first profile surface 115 is too large, such as greater than 158 mm, the arc surface is too flat, so that the first comb tooth 113 has insufficient support on the eyelashes during combing, making it difficult to maintain the curled effect, and the mascara is prone to accumulate at the root of the eyelashes.

[0067] Exemplarily, the radius of curvature of the first profile surface 115 is 155.5 mm. The arc surface with this radius of curvature can separate each eyelash like a comb, the pressure of the comb tooth on the eyelashes is uniform, the mascara is scraped into a thin and uniform layer, and the eyelashes are prevented from sticking together due to excessive local mascara.

[0068] The length of the first comb teeth 113 can be 0.25mm-0.6mm. The adsorption area of the short comb teeth is small, the amount of mascara taken by single dipping is limited, and the gap between adjacent first comb teeth 113 is fine and stable, which can prevent the eyelashes from sticking together due to too much mascara. Thus, a natural and distinct eyelash makeup effect is created. Exemplarily, the length of the first comb teeth 113 is 0.3mm. Through the fine operation and precise control of the short comb teeth, precise application of the eyelashes is achieved.

[0069] The distance between the adjacent two first comb teeth 113 along the length direction X of the brush rod 11 can be 0.2mm-0.4mm. The distance between the adjacent two first comb teeth 113 is adapted to the diameter of the eyelashes, which can accurately capture single eyelashes and separate the cluster of eyelashes into single ones, achieving the effect of distinct roots. Exemplarily, the distance between the adjacent two first comb teeth 113 along the length direction X of the brush rod 11 is 0.25mm.

[0070] Optionally, referring 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 is adjacent to the second sub-side wall 112b and is arranged at an angle; the second comb teeth 114 are arranged between the first sub-side wall 112a and the second sub-side wall 112b, and the second comb teeth 114 are of an integral structure.

[0071] Only one row of second comb teeth 114 is arranged on the second side wall 112, and the length of the second comb teeth 114 is greater than that of the first comb teeth 113. The depth of the tooth groove between the adjacent two second comb teeth 114 is large, so that the second comb teeth 114 have better combing property and can completely card the eyelashes into the tooth groove for combing, thereby creating a dense eyelash makeup effect and making the ends of the eyelashes more slender.

[0072] Optionally, referring 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 contour 116, and along the first direction Z (the direction perpendicular to the paper surface in 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. That is, the second outer contour 116 is configured as a straight line. The straight-line-shaped second outer contour 116 can be parallelly brushed from the root to the tip of the eyelashes. Since the edge of the straight-line-shaped second outer contour 116 is clear, the mascara carried is uniform. When brushing the eyelashes, stable horizontal coverage can be formed, which is suitable for uniform brushing of a large area, can make the mascara distributed uniformly on the middle section of the eyelashes, ensure the basic density, and is not easy to cross the boundary and stain the eyelids. At the same time, the straight-line-shaped second comb teeth 114 can lengthen the tail of the eyelashes and create a slender makeup effect.

[0073] Optionally, the length of the second comb teeth 114 can be 1mm-1.35mm. At this length, the second comb teeth 114 can cover the ends of the eyelashes, lengthen the visual effect of the eyelashes, and also avoid the phenomenon of eyelash clumping or fly legs caused by too long comb teeth carrying too much mascara, thereby achieving a natural and dense 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 tips of the eyelashes, increasing the curling effect. For users with long eyelashes, this length can evenly wrap the entire eyelash, avoiding insufficient mascara application caused by too short comb teeth.

[0074] The gap between the adjacent two second comb teeth 114 along the length direction X of the brush rod 11 is 0.4mm-0.6mm. The size of the gap between the adjacent two comb teeth determines the amount of mascara that the brush head 1 can dip. If the gap is too small, the mascara is easy to accumulate, and if the gap is too large, the mascara is not enough. The gap between the adjacent two second comb teeth 114 of 0.4mm-0.6mm can allow the comb teeth to dip an appropriate amount of mascara, and the mascara is evenly distributed on the eyelashes during application, avoiding clumping caused by too much mascara, or incomplete coverage caused by too little mascara.

[0075] At the same time, the two comb teeth with appropriate gaps can comb the eyelashes one by one during application, separate the eyelashes with the gap between the comb teeth, reduce the clumping phenomenon, and make each eyelash independently adhere to the mascara, showing a clear effect.

[0076] Exemplarily, the length of the second comb teeth 114 can be 1.2mm, and the gap between the adjacent two first comb teeth 113 is 0.5mm.

[0077] Optionally, referring to Figure 6 , the end of the plurality of second comb teeth 114 away from the second side wall 112 has a second outer contour 116. The projection of the second outer contour 116 along a first direction Z is recessed towards 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. That is, along the length direction X of the brush rod 11, the outer contour of the end of the plurality of second comb teeth 114 away from the second side wall 112 is an arc recessed towards the center line of the brush rod 11.

[0078] The second outer contour 116 of the end of the plurality of second comb teeth 114 away from the second side wall 112 is designed to be recessed in the middle, which can better fit the physiological curvature of the eyelid. The slight convexity at the top of the brush head 1 can be used to brush the eyelashes at the details of the eye head and the eye tail, making the overall makeup more delicate and three-dimensional. Moreover, when the brush head 1 moves to apply the mascara, the comb teeth can evenly cover from the root to the tip of the eyelashes, especially for the curved areas such as the eye tail that are prone to missed application, reducing the white spots or uneven application.

[0079] The radius of curvature of the second outer contour 116 can be 140mm-158mm. The radius of curvature of 140mm-158mm is close to the physiological arc of most people's eyelids, so that the second outer contour 116 can closely fit the growth direction of the eyelashes. When brushing the upper eyelashes, the second outer contour 116 can wrap the eyelashes, so that the eyelash root to the eyelash tail can be evenly covered with mascara, and the problem of missed brushing caused by unmatched arc can be avoided.

[0080] In addition, the radius of curvature of 140mm-158mm is close to the circular arc trajectory of natural hand swing, so that the wrist posture does not need to be deliberately adjusted during use, and in particular when brushing the tail of the eye or the lower eyelashes, the arm fatigue can be reduced, and the operation fluency can be improved.

[0081] The radius of curvature of the second outer contour 116 cannot be too small. If the radius of curvature of the second outer contour 116 is too small, such as less than 140mm, the change in the arc of the second outer contour 116 is too large, which can cause the pulling force of the second comb teeth 114 on the eyelashes to be too large, and the eyelashes can be easily broken or the curling arc can be damaged. If the radius of curvature of the second outer contour 116 is too large, such as greater than 158mm, the arc surface is too flat, the supporting force of the second comb teeth 114 on the eyelashes is insufficient during combing, the curling effect is difficult to maintain, and the mascara can be easily accumulated at the root of the eyelashes.

[0082] Exemplarily, the radius of curvature of the second outer contour 116 can be 155.5mm. The arc surface of the radius of curvature can separate each eyelash like a comb, the pressure of the comb teeth on the eyelashes is uniform, the mascara is “scraped” into a thin and uniform layer, and the problem of eyelash adhesion caused by excessive local mascara can be reduced.

[0083] The length of the second comb teeth 114 can be 0.8mm-1.35mm, so that the “liquid storage groove” formed by the comb teeth gap has a large volume and can dip more mascara, which is suitable for users who pursue the effect of thickening. At the same time, the length of the second comb teeth 114 is about 0.8mm-1.35mm, which is the effective contact length, can cover a longer eyelash at a time, reduces the number of repeated brushing, and improves the operation efficiency.

[0084] In one embodiment, with reference to Figure 7The second outer contour 116 of the plurality of second bristles 114 away from the one end of the second side wall 112 protrudes towards the center line of the brush rod 11 in the first direction Z, which is perpendicular to the length direction X of the brush rod 11. In the length direction X of the brush rod 11, the outer contour of the plurality of second bristles 114 away from the one end of the second side wall 112 is an arc protruding towards the center line of the brush rod 11. The second outer contour 116 of the plurality of second bristles 114 is configured as an outwardly convex arc, which can better fit the natural curvature of the eyelashes at the eye head or the eye tail when applying mascara, so that the outer bristles can extend into the corner of the eye tail, reducing missed brushing. The middle part of the plurality of second bristles 114 forms an outwardly convex structure, which can reduce the situation that the second bristles 114 rub against the eyelid when brushing the mascara, and the second outer contour 116 corresponding to the adjacent two second bristles 114 has a deeper depth, carries more mascara, has better combing performance, and can create dense, long and curly eyelashes. At the same time, the second bristles 114 can also remove excess mascara from the eyelashes when combing the eyelashes, thereby reducing eyelash clumping. In addition, the protruding part of the second bristles 114 can also be used for locally lengthening and thickening the eyelashes to create different makeup styles.

[0085] Optionally, with reference 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, the first sub-side wall 112a is adjacent to and angularly arranged with the second sub-side wall 112b; the second bristles 114 include a first sub-bristle 114a and a second sub-bristle 114b, the first sub-bristle 114a is arranged on the first sub-side wall 112a, and the second sub-bristle 114b is arranged on the second sub-side wall 112b, the first sub-bristle 114a and the second sub-bristle 114b are a split structure.

[0086] Along the circumference of the brush rod 11, there is a gap between the first sub-bristle 114a and the second sub-bristle 114b, which can carry mascara. During the process of using the first sub-bristle 114a and the second sub-bristle 114b to comb the eyelashes, the eyelashes clamped in the gap between the first sub-bristle 114a and the second sub-bristle 114b can uniformly dip the mascara in the gap, thereby making the brushed eyelashes more uniform and dense. Exemplarily, the width of the end of the first sub-bristle 114a connected with the first sub-side wall 112a along the circumference of the brush rod 11 is greater than the width of the free end of the first sub-bristle 114a, and the width of the end of the second sub-bristle 114b connected with the second sub-side wall 112b along the circumference of the brush rod 11 is greater than the width of the free end of the second sub-bristle 114b. Therefore, from the root of the bristle to the free end, the gap between the first sub-bristle 114a and the second sub-bristle 114b along the circumference of the brush rod 11 gradually increases, which can carry more mascara, so that the eyelashes clamped in the gap can dip more mascara, thereby making the eyelashes more uniform and dense.

[0087] Optionally, referring to Figure 8 and Figure 9 , along the length direction X of the brush rod 11, the plurality of first sub-teeth 114a and the plurality of second sub-teeth 114b are staggered. That is, the second sub-teeth 114b are arranged at the gaps between the adjacent two first sub-teeth 114a, and the plurality of first sub-teeth 114a and the plurality of second sub-teeth 114b are staggered, which can better control the gap depth between the adjacent two teeth and the width of the gap along the length direction of the brush rod 11. The deeper and wider gap can carry more mascara, and the root of the eyelashes can be coated with more mascara when brushing the mascara. The width of the gap between the adjacent two teeth along the circumferential direction of the brush rod 11 is relatively small, and the length of the gap between the adjacent two teeth along the circumferential direction of the brush rod 11 is relatively small, so the mascara carried is also relatively small, thereby reducing the damage to the overall makeup effect caused by too much mascara applied to the end of the eyelashes.

[0088] In addition, the plurality of first sub-teeth 114a and the plurality of second sub-teeth 114b are staggered, and the two adjacent first sub-teeth 114a along the length direction of the brush rod 11 and the corresponding second sub-teeth 114b between the two first sub-teeth 114a form a cavity region. When using the brush head 1 to apply mascara, the adjacent two first sub-teeth 114a and the corresponding second sub-teeth 114b will comb the roots of the plurality of eyelashes, and the tips of the plurality of eyelashes will fall into the same strong-strong region between the two adjacent teeth, so that the plurality of eyelashes are aggregated into a cluster at the end of the eyelashes, thereby achieving a cluster-shaped eyelash makeup effect.

[0089] Optionally, referring to Figure 10 , along the length direction X of the brush rod 11, the plurality of second teeth 114 has a second outer contour 116 at the end away from the second side wall 112, and the projection of the second outer contour 116 along the first direction Z 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. The end of the plurality of second teeth 114 away from the second side wall 112 is configured to have the second outer contour 116, and the second outer contour 116 is configured as a plane. That is, the outer contour of the end of the first sub-tooth 114a away from the second side wall 112 and the outer contour of the end of the second sub-tooth 114b away from the second side wall 112 together form the second outer contour 116, and the second outer contour 116 is configured as a plane. The projection of the second outer contour 116 along the first direction Z is a straight line and is parallel to the center line of the brush rod 11. The plurality of second teeth 114 with a planar outer contour uniformly carries mascara, and when brushing the eyelashes, it can form a stable transverse coverage, which is suitable for uniform brushing of a large area, and can uniformly distribute the mascara on the middle section of the eyelashes to ensure the basic density.

[0090] Optionally, referring to Figure 11The second outer contour 116 is concave towards the center line of the brush rod 11 in the first direction Z. The first end of the first sub-comb tooth 114a has a concave arc-shaped outer contour, and the first end of the second sub-comb tooth 114b has a concave arc-shaped outer contour, which together form the second outer contour 116. The second outer contour 116 is configured as a concave arc surface, and the projection of the second outer contour 116 in the first direction Z is a concave arc line. The second comb tooth 114 can act on the root of the eyelash, and the concave arc shape can wrap the eyelash, so that the eyelash root is more dense, and the two side comb teeth can assist in separating the eyelashes, thereby creating a “clear root” dense makeup effect.

[0091] At the same time, the curvature of the second outer contour formed by the plurality of second comb teeth 114 is more in line with the curve of the eye. 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 gap depth between the second comb teeth 114 at both ends of the brush head 1 is greater than the tooth gap depth between the second comb teeth 114 in the middle of the brush head 1. The second comb teeth 114 at both ends of the brush head 1 can be used to brush the eyelashes at the head and tail of the eye, and can cover the middle and end of the eyelashes, thereby creating a more dense and curled eyelash makeup effect. The second comb teeth 114 in the middle of the brush head 1 carry relatively less mascara, and create a more natural and long eyelash makeup effect with clear roots. At the same time, the second comb teeth 114 with smaller length can extend into the root of the eyelash, ensuring that the mascara can be applied in place and reducing the accumulation of mascara at the root of the eyelash.

[0092] Exemplarily, the radius of curvature of the second outer contour 116 can be 140mm-158mm. The second comb tooth 114 can closely fit the growth direction of the eyelash, and when brushing the upper eyelash, the second comb tooth 114 can wrap the eyelash, so that the eyelash root to the eyelash tail can be evenly covered with mascara, and the missed brushing caused by the mismatch of the curvature can be reduced.

[0093] In the length direction X of the brush rod 11, the distance between the adjacent two second comb teeth 114 is 0.25mm. When the brush head 1 passes through the eyelash, the 0.25mm gap can accurately clamp a single eyelash between the adjacent two comb teeth, avoiding the adhesion caused by the entry of two eyelashes into the gap at the same time.

[0094] Optionally, with reference to Figure 12The second outer contour 116 of the plurality of second bristles 114 away from the second side wall 112 has a second outer contour 116 in the first direction Z, and the projection of the second outer contour 116 protrudes away from the center line of the brush rod 11. The outer contour of the end of the first sub-bristle 114a away from the second side wall 112 is an arc protruding away from the center line of the brush rod 11, and the outer contour of the end of the second sub-bristle 114b away from the second side wall 112 is an arc protruding away from the center line of the brush rod 11, which together form the second outer contour 116. The second outer contour 116 is configured as an arc protruding away from the center line of the brush rod 11, and the projection of the second outer contour 116 in the first direction Z is an outwardly convex arc. When the second bristles 114 are used to brush the eyelashes, if the second outer contour 116 is configured as an outwardly convex arc, the second bristles 114 can better fit the natural curvature of the tail eyelashes, allowing the outer bristles to extend into the corner of the tail, reducing missed brushing.

[0095] At the same time, the middle part of the plurality of second bristles 114 forms a convex structure, which can reduce the situation that the second bristles 114 touch the eyelid when brushing mascara, and the depth between the corresponding adjacent two second bristles 114 of the convex second outer contour 116 is deeper, carrying more mascara, having better combing performance, and being able to create dense and long and curly eyelashes. At the same time, the second bristles 114 can also remove excess mascara on the eyelashes when combing, thereby reducing eyelash clumping. The convex part of the second bristles 114 can also be used to locally lengthen and thicken the eyelashes to create different makeup styles.

[0096] The radius of curvature of the second outer contour 116 can be 47.5 mm. The highest point of the outward convexity corresponds to the eyelashes in the middle region of the eyelid, and the outward convex arc segment with a radius of curvature of 47.5 mm can apply more mascara to the longer eyelashes in the middle region of the eyelid to enhance the length and density of the makeup effect.

[0097] The length of the second bristles 114 can be 0.3 mm. The second bristles 114 can be parallel to the edge of the eyelid to attach the mascara to the root of the eyelashes, avoiding the long bristles from touching the lower eyelid skin due to excessive inclination angle, or causing excessive mascara to be carried between adjacent two bristles due to excessive length of the second bristles 114, resulting in adhesion of the eyelash roots.

[0098] In an optional embodiment, the distance between adjacent two first bristles 113 in the length direction X of the brush rod 11 is smaller than the distance between the first sub-bristle 114a and the second sub-bristle 114b. The second bristles 114 with larger spacing can carry more mascara, thereby creating a dense eyelash makeup effect. The first bristles 113 with smaller spacing carry less mascara, making it easier to create a natural and long eyelash makeup effect.

[0099] Optionally, at least one of the first sub-side wall 112a and the second sub-side wall 112b is configured as a plane. The plane structure of the side wall provides stable support for the arrangement of the second comb teeth 114, reduces the bending of the second comb teeth 114, improves the rigidity of the whole brush head 1, and enables the second comb teeth 114 to push or press the mascara more effectively when applying the mascara, thereby improving the force exerted by the second comb teeth 114 on the eyelashes and achieving more precise control and improving the makeup efficiency.

[0100] In an optional embodiment, referring to Figure 5 and Figure 9 , the first sub-side wall 112a and the second sub-side wall 112b are connected, and the connection between the first sub-side wall 112a and the second sub-side wall 112b is convex towards the center line away from 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 as a slope, and the side of the first sub-side wall 112a away from the second sub-side wall 112b stores more mascara than the side of the first sub-side wall 112a close to the second sub-side wall 112b; the distance between the side of the second sub-side wall 112b close to the first sub-side wall 112a and the center line of the brush rod 11 is greater than the distance between the side of the second sub-side wall 112b away from the first sub-side wall 112a and the center line of the brush rod 11, and the second sub-side wall 112b is formed as a slope, and the side of the second sub-side wall 112b away from the first sub-side wall 112a stores more mascara than the side of the second sub-side wall 112b close to the first sub-side wall 112a. Exemplarily, the included angle between the first sub-side wall 112a and the second sub-side wall 112b is obtuse, such as 140°. The connection between the first sub-side wall 112a and the second sub-side wall 112b forms a convex edge, and when the second comb teeth 114a are used 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, reducing the phenomenon of eyelashes sticking together or fly legs caused by applying too much mascara on the eyelashes.

[0101] Optionally, the second comb tooth 114 includes oppositely arranged first top end and first bottom end, the first bottom end is connected with the second side wall 112, and the cross-sectional area of the second comb tooth 114 gradually decreases in the direction 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.

[0102] The second comb tooth 114 is configured in an approximate triangular shape, and the first top end and the first bottom end are oppositely arranged. The first bottom end of the second comb tooth 114 connected with the second side wall 112 has a larger cross-sectional area, which can provide stable support force and carry more mascara. The first top end of the second comb tooth 114 has a smaller cross-sectional area and carries less mascara. The first top end of the second comb tooth 114 can extend into the gap of the eyelash root, which can realize precise makeup of single eyelash and reduce the clumping of the eyelash root. The first bottom end carrying more mascara can lengthen the tail of the eyelash.

[0103] Along the length direction X of the brush rod 11, the outer contour of the projection of the second comb tooth 114 includes a first sub-contour line and a second sub-contour line, and the first sub-contour line and the second sub-contour line are both configured as an arc line. That is, the second comb tooth 114 has an arc-shaped outer contour, which can better hold the eyelash when applying mascara, so that the eyelash can be better loaded to create a dense and curly effect.

[0104] Exemplarily, from the direction of 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 second comb tooth 114 described above, and 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 described here.

[0105] In one embodiment, the side of the first comb tooth 113 away from the first side wall 111 has a rounded corner, and the side of the second comb tooth 114 away from the second side wall 112 has a rounded corner, so as to reduce the damage to the skin or the damage to the eyelash when touching the skin. The end of the first comb tooth 113 connected with the first side wall 111 has a rounded corner, and the side of the second comb tooth 114 connected with the second side wall 112 has a rounded corner, so as to facilitate processing.

[0106] Optionally, referring to Figure 13 The first profile surface 115 further includes a fourth region 115d and a fifth region 115e. Along the length direction X of the brush rod 11, the fourth region 115d is arranged on the side of the first region 115a away from the second region 115b, and the fifth region 115e is arranged on the side of the third region 115c away from the second region 115b. The fourth region 115d and the fifth region 115e are both configured as an arc surface protruding away from the center line of the brush rod 11.

[0107] The first profile surface 115 has outwardly convex portions at both ends and an inwardly concave portion in the middle. The outwardly convex fourth region 115d and the fifth region 115e correspond to the first sub-combs 114a with a longer length, which can dip more mascara and is suitable for applying mascara to the root of the eyelashes and other parts that need more mascara to increase the density, helping to create a dense eyelash effect. At the same time, the outwardly convex portion has a certain arc and curve change, which can better fit the arc of the eye, especially the parts such as the eye head and the tail of the eye that are more difficult to brush mascara. The outwardly convex portion can easily extend into the eyelashes of the eye head and the tail of the eye. The inwardly concave portion corresponds to the first comb 113 which is shorter, which can accurately control the amount of mascara, and avoid the eyelashes from sticking together due to too much mascara, so that the eyelashes are distinct.

[0108] Optionally, with reference to Figure 2 、 Figure 4 、 Figure 5 and Figure 9 , along the second direction Y, the first side wall 111 and the second side wall 112 are oppositely arranged on both sides of the brush rod 11, and the second direction Y is perpendicular to the length direction X of the brush rod 11. The first side wall 111 and the second side wall 112 are independent in space, and in use, the plurality of first combs 113 and the plurality of second combs 114 do not interfere with each other, and the user can select to use the first comb 113 or the second comb 114 according to the preference and different makeup needs when using.

[0109] Optionally, with reference to Figure 2 、 Figure 5 and Figure 9 , the brush rod 11 further comprises a third side wall 117 and a fourth side wall 118, and along the first direction Z, the third side wall 117 and the fourth side wall 118 are oppositely arranged, the third side wall 117 is connected with the first side wall 111 and the second side wall 112, the fourth side wall 118 is connected with the first side wall 111 and the second side wall 112, the distance between the third side wall 117 and the fourth side wall 118 along the first direction Z first decreases and then increases, and the second direction Y, the first direction Z and the length direction X of the brush rod 11 are perpendicular to each other. The third side wall 117 and the fourth side wall 118 are also configured as inwardly concave structures toward the center line of the brush rod 11, which can reduce the interference of the third side wall 117 and the fourth side wall 118 on the eyelashes when applying mascara.

[0110] From the direction from the first end 11a to the second end 11b, the size of the first comb 113 near the one end of the third side wall 117 and the one end of the fourth side wall 118 along the first direction Z first decreases and then increases. That is, the third side wall 117 and the fourth side wall 118 are also configured as inwardly concave structures toward the center line of the brush rod 11, which can reduce the interference of the third side wall 117 and the fourth side wall 118 on the eyelashes when applying mascara.

[0111] 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 larger, it can be understood that the size of the first side wall 111 along the first direction Z is larger, the slope of the highest point of the first comb tooth 113 outwardly protruding to both sides is relatively gentle, and the arc is longer. When applying mascara, the first comb tooth 113 with a longer arc can well hold the tail of the eyelashes, so that the tail of the eyelashes is better loaded, and thus the entire eyelash makeup effect is more slender and curled.

[0112] Exemplarily, the third side wall 117 and the fourth side wall 118 can be configured as planes.

[0113] 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 independent in space, and 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. In use, the distance between the plurality of first comb teeth 113 and the plurality of second comb teeth 114 is relatively large and does not interfere with each other.

[0114] Optionally, the brush rod 11, the plurality of first comb teeth 113 and the plurality of second comb teeth 114 are all configured as an integrally formed stainless steel piece. The surface of the stainless steel material is smooth, not easy to adsorb dirt and bacteria, and convenient to clean, thereby improving the eye hygiene.

[0115] Optionally, with reference to Figure 14 , along the length direction X of the brush rod 1, the second side wall 112 includes a first intermediate region 121 and first and second edge regions 122 and 123 located on both sides of the first intermediate region 121. The distance between the first intermediate region 121 and the center line of the brush rod 1 is greater than the distance between the first edge region 122 and the center line of the brush rod 1, and the distance between the first intermediate region 121 and the center line of the brush rod 1 is greater than the distance between the second edge region 123 and the center line of the brush rod 1.

[0116] Along the length direction X of the brush rod 1, the second side wall 112 comprises a first edge area 122, a first intermediate area 121 and a second edge area 123 connected in sequence, the spacing between the first intermediate area 121 and the center line of the brush rod 1 is greater than the spacing between the first edge area 122 and the center line of the brush rod 1, and the spacing between the first intermediate area 121 and the center line of the brush rod 1 is also greater than the spacing between the second edge area 123 and the center line of the brush rod 1. That is, along the length direction X of the brush rod 1, the spacing between the second side wall 112 and the center line of the brush rod 1 first increases and then decreases from the first edge area 122 to the second edge area 123. In other words, the second side wall 112 of the brush rod 1 outwardly protrudes to form an arc surface.

[0117] The second side wall 112 is configured as an outwardly protruding arc surface, so that when the brush head 1 is used to apply mascara, the first intermediate area 121 can well fit the curvature of the middle part of the eye, and the first edge area 122 and the second edge area 123 can adapt to the relatively flat or smaller curvature area such as the corners of the eyes, thereby expanding the contact area between the brush head 1 and the eyelashes and improving the application efficiency. For example, when applying mascara to the upper eyelashes, the first intermediate area 121 can closely fit the curvature above the eyeball to ensure that the mascara is evenly applied to the eyelashes, and the first edge area 122 and the second edge area 123 can be used to apply mascara to the eyelashes at the corners of the eyes.

[0118] In addition, the second side wall 112 of the brush rod 1 outwardly protrudes, 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, and the second side wall 112 of the brush rod 1 can provide an outward and upward supporting force to the eyelashes, so as to better lift the eyelashes upward and thereby improve the curling degree of the eyelashes. The first side wall 111 of the brush rod 1 is configured 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.

[0119] Optionally, with reference to Figure 15 , the second side wall 112 is configured as an arc shape; along the length direction X of the brush rod 1, the second side wall 112 comprises a second intermediate area 124 and third and fourth edge areas 125 and 126 located on both sides of the second intermediate area 124, the spacing between the second intermediate area 124 and the center line of the brush rod 1 is less than the spacing between the third edge area 125 and the center line of the brush rod 1, and the spacing between the second intermediate area 124 and the center line of the brush rod 1 is less than the spacing between the fourth edge area 126 and the center line of the brush rod 1.

[0120] Along the length direction X of the brush rod 1, the second side wall 112 comprises a third edge area 125, a second intermediate area 124 and a fourth edge area 126 connected in sequence, the spacing between the second intermediate area 124 and the center line of the brush rod 1 is smaller than the spacing between the third edge area 125 and the center line of the brush rod 1, and the spacing between the second intermediate area 124 and the center line of the brush rod 1 is also smaller than the spacing between the fourth edge area 126 and the center line of the brush rod 1. That is, along the length direction X of the brush rod 1, the spacing between the second side wall 112 and the center line of the brush rod 1 first decreases and then increases from the third edge area 125 to the fourth edge area 126. In other words, the second side wall 112 of the brush rod 1 is concave inward to form an arc surface.

[0121] The second side wall 112 is configured as a concave structure, and the concave part of the second side wall 112 can temporarily store more mascara liquid, thereby reducing the frequency of frequent dipping, especially when the brush head is pulled out, the concave part can absorb more mascara. And the concave part can guide the mascara to flow to the root of the comb tooth, reducing the probability of excessive accumulation of mascara at the tip of the comb tooth. When applying mascara, the mascara is released more evenly, reducing the phenomenon of clumping or "fly leg". The concave second side wall 112 can enhance the wrapping of the comb tooth on the eyelashes, and cooperate with the mascara to create long-lasting, curled and curled eyelashes.

[0122] In a second aspect, with reference to Figure 16 and Figure 17 The embodiments of the present application also provide a mascara brush, which comprises a brush handle 2 and the brush head 1 described in any of the above embodiments, and the brush handle 2 is connected to one end of the brush rod 11 along the length direction. The brush handle 2 provides a hand holding force point for the operator to control the brush head 1 to fit the eyelashes and perform uniform brushing, so as to achieve curled, dense and natural mascara makeup effect.

[0123] The brush head 1 and the brush handle 2 can be integrally formed. The integrally formed brush head 1 and brush handle 2 reduce the number of molds, greatly simplify the production process, improve the production efficiency, and reduce the cost. Moreover, the integrally formed brush head 1 and brush handle 2 can reduce the connection gap between the parts, so that the brush head 1 is easier to clean and less likely to hide dirt, thereby reducing bacterial growth.

[0124] Optionally, with reference to Figure 17 The brush head 1 and the brush handle 2 are arranged 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, thereby reducing the fatigue of the user, and the brush head is easier to be parallel to the arc of the eyelid, so that the entire row of comb teeth can fully contact the eyelashes from the root to the tip, thereby improving the wrapping efficiency and the uniformity of the brushing. The angle between the brush head 1 and the brush handle 2 can be freely selected according to the needs of the user, which is not limited herein. Exemplarily, the angle between the brush head 1 and the brush handle 2 is 3-12 degrees, which is more in line with the holding habits of the user, so that the user can use a more comfortable holding posture to perform brushing at the corner of the eye and other positions.

[0125] It should also be noted that the terms "comprising," "comprises," "including," "includes" or other variations thereof are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0126] The various embodiments in the specification are described in progressive manner, and the same or similar parts between the various embodiments can be mutually referred to, and each embodiment focuses on the difference from other embodiments.

[0127] The above only describes the embodiments of the present application and is not intended to limit the present application.
