Description

Technical Field

[0001] The present application relates to the technical field of cosmetic products, and particularly relates 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. The eyelash brush is dipped in mascara and used for eyelash priming, curling and shaping, lengthening eyelashes, making eyelashes thick, and making each eyelash distinct, natural and slender.

[0003] Currently, the shape designs of some eyelash brush heads do not fit the eye shape well. For example, when applying the eyelashes at the inner and outer corners of the eyes with some straight cylindrical brush heads, it is difficult to accurately cover and evenly brush, resulting in insufficient modification of the eyelashes in these areas and the makeup effect not being natural enough and the eyelashes not being curled enough. Utility Model Content

[0004] The present application provides a brush head for an eyelash brush and an eyelash brush, which can improve the eyelash separation and application effect, making the eyelashes more natural and more curled.

[0005] To achieve the above object, the main technical solutions adopted by the present application include:

[0006] In a first aspect, an embodiment of the present application provides a brush head for an eyelash brush, including a base shaft, a first brush body and a second brush body. The circumferential surface of the base shaft includes a first side wall and a second side wall, and at least one of the first side wall and the second side wall is configured as a plane; the first brush body is disposed on the first side wall, and the first brush body includes a plurality of first bristles, and the plurality of first bristles are arranged at intervals along the length direction of the base shaft; the second brush body is disposed on the second side wall, the second brush body has an outer contour away from the second side wall, the outer contour is configured as an arc, the second brush body includes a plurality of second bristles, the plurality of second bristles are arranged at intervals along the length direction of the base shaft, and one ends of the plurality of second bristles away from the second side wall together form the outer contour.

[0007] In the brush head for an eyelash brush proposed by the embodiment of the present application, the first brush body and the second brush body are respectively disposed on the first side wall and the second side wall of the base shaft, and at least one of the first side wall and the second side wall is configured as a plane, so that it is easier for the user to control the angle and strength of the brush head when applying eyelashes. When the plurality of second bristles with an arc-shaped outer contour contact the eyelashes, the mascara can be evenly applied from the root to the tip of the eyelashes, enabling the eyelashes to curl naturally upward or outward, reducing the situation where the mascara accumulates at the root of the eyelashes, and thus reducing the probability of eyelash clumping and spider leg phenomenon.

[0008] Optionally, along the circumferential direction of the base shaft, the first side wall and the second side wall are adjacent to each other.

[0009] In the above solution, the first side wall and the second side wall are arranged adjacent to each other, that is, the first brush body and the second brush body are arranged adjacent to each other, and a plurality of first bristles and a plurality of second bristles are arranged adjacent to each other, so that the first brush body and the second brush body can be better connected during operation and can cooperate more closely.

[0010] Optionally, along the first direction, the first side wall and the second side wall are oppositely arranged on both sides of the base shaft, and the first direction is perpendicular to the length direction of the base shaft.

[0011] In the above solution, the first side wall and the second side wall are oppositely arranged, that is, the first brush body and the second brush body are oppositely arranged, and a plurality of first bristles and a plurality of second bristles are oppositely arranged. The first brush body and the second brush body are spatially independent of each other. When in use, a plurality of first bristles and a plurality of second bristles do not interfere with each other, and the user can choose to use the first bristles or the second bristles according to their preferences and different makeup needs when using.

[0012] Optionally, the brush head formed by the first brush body, the base shaft and the second brush body is a flat structure.

[0013] In the above solution, the first brush body and the second brush body are respectively located on opposite sides of the base shaft, so that the first brush body and the second brush body are spatially independent of each other. When in use, a plurality of first bristles and a plurality of second bristles do not interfere with each other, reducing the phenomenon of "fly legs" caused by too much mascara on the first brush body or the second brush body.

[0014] Optionally, the first brush body further includes a first base, the first base is arranged on the first side wall, and along the length direction of the base shaft, the cross-section of the first base is an arc surface, and the first bristles are arc-shaped along the circumferential direction of the base shaft and are connected to the first base.

[0015] In the above solution, along the length direction of the base shaft, the first base is an arc surface, the first bristles are connected to the first base, and the first bristles are arc-shaped along the axial direction of the base shaft, which can increase the amount of mascara accommodated between the first bristles and make it easier to create thick and curly eyelashes when applying mascara.

[0016] Optionally, the second side wall is an arc surface. Along the length direction of the base shaft, the second side wall includes a middle region and a first edge region and a second edge region located on both sides of the middle region. The distance between the middle region and the center line of the base shaft is greater than the distance between the first edge region and the center line of the base shaft, and the distance between the middle region and the center line of the base shaft is greater than the distance between the second edge region and the center line of the base shaft.

[0017] In the above solution, the distance between the middle region and the center line of the base shaft is large, while the distances between the first edge region and the second edge region on both sides and the center line of the base shaft are small. When the brush head is used to apply mascara to the eyelashes, the middle region can well conform to the curvature of the middle part of the eye, and the first edge region and the second edge region on both sides can adapt to relatively flat or less curved regions such as the eye corners, overall expanding the contact area between the brush head and the eyelashes and improving the application efficiency.

[0018] Optionally, the circumferential surface of the base shaft further includes a third side wall, and the third side wall is adjacent to the first side wall and is arranged at an angle; the brush head further includes a third brush body, and the third brush body is arranged on the third side wall. The third brush body includes a plurality of third bristles, and the plurality of third bristles are arranged at intervals along the length direction of the base shaft.

[0019] In the above solution, the third side wall is adjacent to the first side wall and is arranged at an angle, so that the third brush body arranged on the third side wall can approach the root of the eyelashes at an angle different from that of the first side wall, apply at the root of the eyelashes, increase the density at the root, create a natural and supportive eyelash effect, and make the eyelashes more curly and three-dimensional.

[0020] Optionally, along the circumferential direction of the base shaft, each of the third bristles is arranged opposite to the corresponding first bristle.

[0021] In the above solution, along the circumferential direction of the base shaft, each first bristle and third bristle are arranged opposite to each other, and the mascara on the first bristle and the third bristle acts on the eyelashes in a superimposed manner, increasing the density at the root, and the application effect is more uniform, thereby creating a natural and supportive eyelash effect and making the eyelashes more curly and three-dimensional.

[0022] Optionally, along the length direction of the base shaft, the base shaft has a first end; the plurality of first bristles include first sub-bristles close to the first end, and the first sub-bristles are arranged obliquely with respect to the first end. The plurality of third bristles include third sub-bristles close to the first end, and the third sub-bristles are arranged obliquely with respect to the first end.

[0023] In the above solution, the first sub-bristles and the third sub-bristles arranged obliquely with respect to the first end can be used for local application. For example, if the eyelashes in a certain area are not applied properly or are missed, the obliquely arranged first sub-bristles and third sub-bristles can be used for local supplementation.

[0024] Optionally, the second side wall is configured as a curved surface, and along the length direction of the base axis, the second side wall includes a middle area and a first edge area and a second edge area located on both sides of the middle area, the distance between the middle area and the center line of the base axis is greater than the distance between the first edge area and the center line of the base axis, and the distance between the middle area and the center line of the base axis is greater than the distance between the second edge area and the center line of the base axis.

[0025] In the above scheme, the distance between the middle area and the center line of the base axis is large, while the distance between the first edge area and the second edge area on both sides and the center line of the base axis is small, so that when the brush head is brushing the eyelashes, the middle area can fit the curvature of the middle part of the eye well, and the first edge area and the second edge area on both sides can adapt to relatively flat or smaller curvature areas such as the corners of the eyes, which overall expands the contact area between the brush head and the eyelashes and improves the brushing efficiency.

[0026] Optionally, the base shaft, the first brush body and the second brush body are an integrally formed part.

[0027] In the above solution, the base shaft, the first brush body and the second brush body are integrally formed, which reduces the number of molds, greatly simplifies the production process, improves production efficiency and reduces costs. It can also reduce the connection gaps between components, making the brush head easier to clean, less likely to harbor dirt and reduce bacterial growth.

[0028] Optionally, the base shaft, the first brush body and the second brush body are all constructed as stainless steel parts.

[0029] In the above scheme, the surface of the stainless steel brush head is smooth, and the stainless steel material is easy to clean. It can be cleaned by rinsing with water after use, which can reduce the growth and hiding of bacteria.

[0030] In a second aspect, an embodiment of the present application further provides a mascara brush, comprising a brush handle and a brush head as described in any of the above embodiments; the brush handle is connected to one end of the base axis along the length direction.

[0031] In the above scheme, the brush handle provides the operator with a holding point to control the brush head to fit the eyelashes and apply the makeup evenly to achieve a curled, thick and natural eyelash makeup effect.

[0032] Optionally, the brush head and the brush handle are integrally formed.

[0033] In the above solution, the brush head and the brush handle are integrally formed, which reduces the number of molds, greatly simplifies the production process, improves production efficiency, and reduces costs. In addition, the integral formation of the brush head and the brush handle can reduce the connection gap between the components, making the brush head easier to clean, less likely to harbor dirt, and reducing bacterial growth.

[0034] Optionally, both the brush head and the brush handle are configured as stainless steel parts.

[0035] In the above solution, the surface of the stainless steel material is smooth, and the stainless steel material is easy to clean. After use, it can be cleaned simply by rinsing with water, which can reduce the growth and hiding of bacteria. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Referring to "embodiments" in the present application means that specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those of ordinary skill in the art will explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0052] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "coupled" and "attached" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0053] The term "and / or" in the present application is only an associative relationship describing associated objects and indicates that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present application generally represents an "or" relationship between the associated objects before and after.

[0054] In this application, "multiple" means two or more (including two). Similarly, "multiple groups" means two or more groups (including two groups), and "multiple pieces" means two or more pieces (including two pieces).

[0055] Currently, the shape designs of some mascara brush heads do not fit the eye shape well. For example, when applying the mascara to the inner and outer corner lashes with some straight barrel-shaped brush heads, it is difficult to accurately cover and evenly brush, resulting in the lashes in these areas not being fully groomed, and the makeup effect not being natural enough and the lashes not being curly enough. In view of this, this application provides a new mascara brush and a mascara brush head to improve the lash separation and application effect, making the lashes more natural and curly.

[0056] In the first aspect, referring to Figures 1 to 6 , an embodiment of this application provides a brush head 100 for a mascara brush. The brush head 100 includes a base shaft 1, a first brush body 2, and a second brush body 3. The peripheral surface of the base shaft 1 includes a first side wall 11 and a second side wall 12, and at least one of the first side wall 11 and the second side wall 12 is configured as a plane; the first brush body 2 is disposed on the first side wall 11, and the first brush body 2 includes a plurality of first bristles 21, and the plurality of first bristles 21 are spaced apart along the length direction A of the base shaft 1; the second brush body 3 is disposed on the second side wall 12, the second brush body 3 has an outer contour away from the second side wall 12, and the outer contour is configured as an arc. The second brush body 3 includes a plurality of second bristles 31, and the plurality of second bristles 31 are spaced apart along the length direction A of the base shaft 1, and the ends of the plurality of second bristles 31 away from the second side wall 12 together form an outer contour.

[0057] The peripheral surface of the base shaft 1 includes a first side wall 11 and a second side wall 12. One of the first side wall 11 and the second side wall 12 is configured as a plane, or both the first side wall 11 and the second side wall 12 are configured as planes. Compared with the traditional cylindrical base shaft 1, the base shaft 1 with a planar side wall can provide better holding stability and controllability. When applying mascara, the user can more easily control the angle and strength of the brush head 100, can more accurately apply the mascara to the lashes, reduce application mistakes, and improve the makeup effect.

[0058] The second brush body 3 includes a plurality of second bristles 31, and the ends of the plurality of second bristles 31 away from the second side wall 12 together form an outer contour. That is to say, the ends of the plurality of second bristles 31 away from the second side wall 12 together form an arc-shaped outer contour. The second bristles 31 with an arc-shaped outer contour can better fit the natural curve of the eye lashes. During use, they can come into closer contact with the lashes, and can evenly apply the mascara from the root to the tip of the lashes, making the lashes look more natural, curly, and thick, and increasing the three-dimensional sense and beauty of the eyes.

[0059] A plurality of first bristles 21 are arranged at intervals along the length direction A of the base shaft 1, and a plurality of second bristles 31 are also arranged at intervals along the length direction A of the base shaft 1. Each first bristle 21 and each second bristle 31 can independently contact the eyelashes, evenly distribute the mascara on the eyelashes, make the eyelashes distinct from each other, and present a natural and delicate makeup effect.

[0060] The plurality of first bristles 21 and the plurality of second bristles 31 can carry more mascara, reduce the number of times of repeatedly dipping the mascara when applying the mascara to the eyelashes, and improve the makeup application efficiency. At the same time, the plurality of second bristles 31 with an arc-shaped outer contour can act on the eyelashes simultaneously, evenly apply the mascara on each eyelash at a suitable angle, reduce the situation that the mascara stains the skin in the inner corner of the eye, and the plurality of second bristles 31 arranged in an arc shape can be applied along the growth direction of the eyelashes, so as to achieve the effect of thickening and naturally curling upward or outward of the eyelashes in a short time, saving makeup time. The second brush body 3 in the present application can be used for preliminary brushing and priming, and the first brush body 2 can be used to assist the second brush body 3 to further thicken and curl the eyelashes.

[0061] In the brush head 100 for an eyelash brush proposed in the embodiment of the present application, the first brush body 2 and the second brush body 3 are respectively arranged on the first side wall 11 and the second side wall 12 of the base shaft 1, and at least one of the first side wall 11 and the second side wall 12 is configured as a plane, so that it is easier for the user to control the angle and strength of the brush head 100 when applying the mascara to the eyelashes. When the plurality of second bristles 31 with an arc-shaped outer contour contact the eyelashes, the mascara can be evenly applied from the root to the tip of the eyelashes, so that the eyelashes can naturally curl upward or outward, reducing the situation that the mascara accumulates at the root of the eyelashes, thereby reducing the probability of eyelash clumping and spider leg phenomenon.

[0062] Optionally, along the circumferential direction of the base shaft 1, the first side wall 11 and the second side wall 12 are adjacently arranged.

[0063] The adjacent arrangement of the first side wall 11 and the second side wall 12 means that the first brush body 2 and the second brush body 3 are adjacently arranged, and the plurality of first bristles 21 and the plurality of second bristles 31 are adjacently arranged, so that the first brush body 2 and the second brush body 3 can be better connected during operation and can cooperate more closely. For example, the second brush body 3 is responsible for brushing the eyelashes, and the first brush body 2 is responsible for increasing the curl and density of the eyelashes. During use, the plurality of second bristles 31 of the second brush body 3 can be used to brush and apply the eyelashes first, and then the plurality of first bristles 21 of the first brush body 2 can be used for curling treatment. The two complement each other, so as to more smoothly complete the operation of different parts of the eyelashes or different makeup steps. Or, first use the first brush body 2 to apply the mascara to the root of the eyelashes to make the root of the eyelashes thick and curled, and then naturally transition to using the second brush body 3 to comb the eyelashes, and the whole application process is more smooth, so as to create a uniform and natural eyelash makeup effect.

[0064] Optionally, the first side wall 11 and the second side wall 12 are spaced apart circumferentially along the base axis 1.

[0065] The first side wall 11 and the second side wall 12 are spaced apart, that is, the first brush body 2 and the second brush body 3 are spaced apart, and the plurality of first bristles 21 and the plurality of second bristles 31 are spaced apart. The first brush body 2 and the second brush body 3 are independent of each other in space. When in use, the plurality of first bristles 21 and the plurality of second bristles 31 do not interfere with each other. When using, the user can choose to use the first bristles 21 or the second bristles 31 or use the first bristles 21 and the second bristles 31 in sequence according to personal preference and different makeup requirements.

[0066] Optionally, along the first direction B, the first side wall 11 and the second side wall 12 are oppositely arranged on both sides of the base axis 1, and the first direction B is perpendicular to the length direction A of the base axis 1.

[0067] The first side wall 11 and the second side wall 12 are oppositely arranged along the first direction B, that is, the first brush body 2 and the second brush body 3 are oppositely arranged, and the plurality of first bristles 21 and the plurality of second bristles 31 are oppositely arranged. The first brush body 2 and the second brush body 3 are independent of each other in space. When in use, the plurality of first bristles 21 and the plurality of second bristles 31 do not interfere with each other. When using, the user can choose to use the first bristles 21 or the second bristles 31 or use the first bristles 21 and the second bristles 31 in sequence according to personal preference and different makeup requirements.

[0068] In addition, during the use process, the spaced-apart plurality of first bristles 21 and the plurality of second bristles 31 can reduce the situation that the mascara on the second brush body 3 gets smeared on the already applied eyelashes when using the first brush body 2. Vice versa. By spacing apart the plurality of first bristles 21 and the plurality of second bristles 31, the plurality of first bristles 21 or the plurality of second bristles 31 can better complete their preset functions and improve the accuracy of makeup application.

[0069] It should be understood that compared with having bristles arranged circumferentially along the base axis 1, in the present application, the first bristles 21 and the second bristles 31 are spaced apart circumferentially along the base axis 1, which has better combability, is easier to control, better fits the characteristics and needs of the eyes, and reduces the probability of accidentally hurting the eyes.

[0070] Optionally, the brush head 100 formed by the first brush body 2, the base axis 1, and the second brush body 3 is configured as a flat structure.

[0071] The first brush body 2 and the second brush body 3 are respectively located on opposite sides of the base axis 1, so that the first brush body 2 and the second brush body 3 are independent of each other in space. When in use, the plurality of first bristles 21 and the plurality of second bristles 31 do not interfere with each other, reducing the "fly legs" phenomenon caused by excessive mascara on the first brush body 2 or the second brush body 3.

[0072] Optionally, referring to Figure 4 , the first brush body 2 further includes a first base 22. The first base 22 is disposed on the first side wall 11. Along the length direction A of the base axis 1, the cross-section of the first base 22 is configured as an arc surface. The first bristles 21 are configured as an arc along the circumferential direction of the base axis 1 and are connected to the first base 22.

[0073] Along the length direction A of the base axis 1, the first base 22 is configured as an arc surface, the first bristles 21 are connected to the first base 22, and the first bristles 21 are configured as an arc along the axial direction of the base axis 1, which can increase the amount of mascara accommodated between the first bristles 21. When applying mascara to the eyelashes, it is easier to create thick and curly eyelashes.

[0074] Optionally, referring to Figure 5 , the second side wall 12 is configured as an arc surface. Along the length direction A of the base axis 1, the second side wall 12 includes an intermediate region 121 and a first edge region 122 and a second edge region 123 located on both sides of the intermediate region 121. The distance between the intermediate region 121 and the center line 14 of the base axis 1 is greater than the distance between the first edge region 122 and the center line 14 of the base axis 1, and the distance between the intermediate region 121 and the center line 14 of the base axis 1 is greater than the distance between the second edge region 123 and the center line 14 of the base axis 1.

[0075] Specifically, the first side wall 11 is configured as a plane, and the second side wall 12 is configured as an arc surface. Along the length direction A of the base axis 1, the second side wall 12 includes a first edge region 122, an intermediate region 121, and a second edge region 123 that are connected in sequence. The distance between the intermediate region 121 and the center line 14 of the base axis 1 is greater than the distance between the first edge region 122 and the center line 14 of the base axis 1, and the distance between the intermediate region 121 and the center line 14 of the base axis 1 is also greater than the distance between the second edge region 123 and the center line 14 of the base axis 1. That is to say, along the length direction A of the base axis 1, from the first edge region 122 to the second edge region 123, the distance between the second side wall 12 and the center line 14 of the base axis 1 first increases and then decreases. In other words, the second side wall 12 of the base axis 1 bulges outwards to form an arc surface, and a plurality of second bristles 31 are provided on the second side wall 12.

[0076] The second side wall 12 is configured as an arc surface, so that when the brush head 100 is brushing the eyelashes, the intermediate region 121 can well fit the curvature of the middle part of the eye, while the first edge region 122 and the second edge region 123 on both sides can adapt to relatively flat or less curved areas such as the corners of the eyes, overall expanding the contact area between the brush head 100 and the eyelashes and improving the brushing efficiency. For example, when brushing the upper eyelashes, the intermediate region 121 can closely fit the curvature above the eyeball to ensure that the mascara is evenly applied to the eyelashes, while the first edge region 122 and the second edge region 123 can brush the eyelashes at the inner and outer corners of the eyes.

[0077] In addition, the second side wall 12 of the base shaft 1 protrudes outward, so that when the second brush body 3 contacts the eyelashes, the second side wall 12 can apply a force at an angle that more conforms to the natural growth direction of the eyelashes. Moreover, the second side wall 12 of the base shaft 1 will give the eyelashes an outward and upward supporting force, which can better lift the eyelashes upward, thereby enhancing the curl of the eyelashes. The first side wall 11 of the base shaft 1 is constructed as a plane to better assist the bristles on the second side wall 12 in applying mascara, thereby achieving a better makeup effect.

[0078] Optionally, referring to Figure 1 , the circumferential surface of the base shaft 1 further includes a third side wall 13, and the third side wall 13 is adjacent to the first side wall 11 and is arranged at an angle; the brush head 100 further includes a third brush body 4, and the third brush body 4 is arranged on the third side wall 13. The third brush body 4 includes a plurality of third bristles 41, and the plurality of third bristles 41 are arranged at intervals along the length direction A of the base shaft 1.

[0079] The third side wall 13 is adjacent to the first side wall 11 and is arranged at an angle, so that the third brush body 4 arranged on the third side wall 13 can approach the root of the eyelashes at an angle different from that of the first side wall 11 and apply it at the root of the eyelashes, increasing the density at the root and making the application effect more uniform, thereby creating a natural and supportive eyelash effect and making the eyelashes more curly and three-dimensional.

[0080] Optionally, along the circumferential direction of the base shaft 1, each third bristle 41 is arranged opposite to the corresponding first bristle 21.

[0081] Along the circumferential direction of the base shaft 1, each first bristle 21 and the third bristle 41 are arranged opposite to each other, and the mascara on the first bristle 21 and the third bristle 41 acts on the eyelashes together. By applying the first bristle 21 and the third bristle 41 in a superimposed manner at the root of the eyelashes, the density at the root is increased, creating a natural and supportive eyelash effect and making the eyelashes more curly and three-dimensional.

[0082] Optionally, referring to Figure 1 and Figure 6 , along the length direction A of the base shaft 1, the base shaft 1 has a first end 15; the plurality of first bristles 21 include first sub-bristles 211 close to the first end 15, and the first sub-bristles 211 are inclined with respect to the first end 15. The plurality of third bristles 41 include third sub-bristles 411 close to the first end 15, and the third sub-bristles 411 are inclined with respect to the first end 15.

[0083] The first end 15 of the base shaft 1 generally corresponds to the canthus or the outer corner of the eye, and the eyelashes in the canthus or the outer corner area are relatively sparse and short. The first sub-bristles 211 are inclined with respect to the first end 15, and the third sub-bristles 411 are inclined with respect to the first end 15, so that the first sub-bristles 211 and the third sub-bristles 411 can better conform to the growth trend of the eyelashes in the canthus or the outer corner area. When applying mascara, the first sub-bristles 211 and the third sub-bristles 411 inclined with respect to the first end 15 can more conveniently contact each eyelash in the canthus or the outer corner, enabling the mascara to evenly cover each eyelash in the canthus or the outer corner, reducing the omission of eyelashes in the canthus or the outer corner, and reducing the probability of insufficient application of mascara to the eyelashes in the canthus or the outer corner.

[0084] In other words, since the eyelashes in the marginal areas such as the canthus and the outer corner differ from those in the middle part of the eye in terms of length, density, and growth angle, the inclined sub-bristles can, by adjusting the contact angle with the eyelashes, more naturally transition the mascara from the dense eyelash area to the relatively sparse marginal area, making the makeup effect of the entire eye eyelashes more coordinated and unified, and effectively improving the transition effect between the eyelashes in the eye marginal area and the eyelashes in the middle area 121 of the eye.

[0085] Optionally, referring to Figure 3 , the second side wall 12 is configured as an arc surface. Along the length direction A of the base shaft 1, the second side wall 12 includes a middle area 121 and a first edge area 122 and a second edge area 123 located on both sides of the middle area 121. The distance between the middle area 121 and the center line 14 of the base shaft 1 is greater than the distance between the first edge area 122 and the center line 14 of the base shaft 1, and the distance between the middle area 121 and the center line 14 of the base shaft 1 is greater than the distance between the second edge area 123 and the center line 14 of the base shaft 1.

[0086] Along the length direction of the base shaft 1, the second side wall 12 includes a middle area 121 and a first edge area 122 and a second edge area 123 located on both sides thereof. The distance between the middle area 121 and the center line 14 of the base shaft 1 is large, while the distances between the first edge area 122 and the second edge area 123 on both sides and the center line 14 of the base shaft 1 are small. When the brush head 100 is applying mascara to the eyelashes, the middle area 121 can well conform to the curvature of the middle part of the eye, while the first edge area 122 and the second edge area 123 on both sides can adapt to relatively flat or less curved areas such as the canthus, generally expanding the contact area between the brush head 100 and the eyelashes and improving the application efficiency. For example, when applying mascara to the upper eyelashes, the middle area 121 can closely conform to the curvature above the eyeball, ensuring that the mascara is evenly applied to the eyelashes, while the first edge area 122 and the second edge area 123 can apply mascara to the eyelashes at the inner and outer corners of the eye.

[0087] In an optional embodiment, the second bristles 31 corresponding to the middle area 121 are longer, and the second bristles 31 corresponding to the first edge area 122 and the second edge area 123 are shorter. The second bristles 31 in the middle area 121 are longer, which can better stretch and brush the eyelashes during brushing, making the eyelashes more curled and neat; the second bristles 31 corresponding to the first edge area 122 and the second edge area 123 are relatively shorter, which can more finely process the eyelashes in the corners of the eyes, reduce the accumulation of mascara in the corners of the eyes, make the eyelashes look more natural, and improve the overall makeup effect.

[0088] Optionally, the base shaft 1, the first brush body 2 and the second brush body 3 are integrally formed. The base shaft 1, the first brush body 2 and the second brush body 3 are integrally formed, which reduces the number of molds to be manufactured, greatly simplifies the production process, improves production efficiency and reduces costs. In addition, the integral formation of the base shaft 1, the first brush body 2 and the second brush body 3 can reduce the connection gap between the components, making the brush head 100 easier to clean, less likely to harbor dirt and reduce bacterial growth.

[0089] In a specific embodiment, the base shaft 1, the first brush body 2 and the second brush body 3 are integrally formed and are all constructed of stainless steel. The surface of stainless steel is smooth, not easy to absorb dirt and bacteria, and is easy to clean, thereby improving eye hygiene.

[0090] In a second aspect, the embodiment of the present application further provides an eyelash brush, comprising a brush handle 200 and a brush head 100 as described in any of the above embodiments; the brush handle 200 is connected to one end of the base axis 1 along the length direction. The brush handle 200 provides a hand-held fulcrum for the operator to control the brush head 100 to fit the eyelashes and apply the brush evenly to achieve a curled, thick and natural eyelash makeup effect.

[0091] Optionally, the brush head 100 and the brush handle 200 are integrally formed. The brush head 100 and the brush handle 200 are integrally formed, which reduces the number of molds to be manufactured, greatly simplifies the production process, improves production efficiency, and reduces costs. In addition, the integral formation of the brush head 100 and the brush handle 200 can reduce the connection gap between the components, making the brush head 100 easier to clean, less likely to harbor dirt, and reducing bacterial growth.

[0092] Optionally, the brush head 100 and the brush handle 200 are both made of stainless steel. The surface of stainless steel is smooth, and its compact metal structure and special process can effectively inhibit the growth and hiding of bacteria. In addition, stainless steel is easy to clean and can be cleaned by rinsing with water after use. Even if the brush is used for a long time or dipped in mascara many times, the surface of the mascara brush can still remain clean and hygienic, thereby reducing the chance of eye discomfort or infection caused by the unclean brush head 100.

[0093] In addition, the stainless steel handle provides a comfortable and stable grip.

The plurality of third bristles 41 include third sub-bristles 411 close to the first end 15, and the third sub-bristles 411 are inclined with respect to the first end 15.

[0097] When applying mascara, the first sub-bristles 211 and the third sub-bristles 411 inclined with respect to the first end 15 can more conveniently contact each eyelash at the inner corner or outer corner of the eye, so that the mascara can evenly cover each eyelash at the inner corner or outer corner of the eye, reducing the omission of eyelashes at the inner corner or outer corner of the eye and reducing the probability of insufficient application of eyelashes at the inner corner or outer corner of the eye.

[0098] In addition, the first sub-bristles 211 and the third sub-bristles 411 inclined with respect to the first end 15 can also be used for local application. For example, if the eyelashes in a certain area are not applied properly or missed, the inclined first sub-bristles 211 and third sub-bristles 411 can be used for local supplementation.
