[0033] As shown in Figs. 1 to 6, in one embodiment of the present invention, a cosmetic tool is provided, which includes a brush head 10, a cosmetic container 20, a movable sleeve 30, a fixed sleeve 40, and a transmission structure.

[0034] The brush head 10 is capable of carrying a cosmetic substance and applying the cosmetic substance to the skin.

[0035] The cosmetic container 20 is for containing cosmetic substances. As can be understood, there is a cavity in the cosmetic container 20 for containing cosmetic substances. The cosmetic substances may be liquid foundation, makeup base, blush, lipstick, highlighter, or other cosmetic substances, without being listed one by one.

[0036] The cosmetic storage unit 20 is attached inside the movable sleeve 30. The brush head 10 is located at one end of the movable sleeve 30 and is provided facing the cosmetic storage unit 20. The cosmetic storage unit 20 has a cosmetic outlet on the end face facing the brush head 10. This cosmetic outlet communicates with the cavity of the cosmetic storage unit 20, and the cosmetic substance is exposed from the cosmetic outlet, allowing the cosmetic substance to be easily applied with the brush head 10.

[0037] The fixed sleeve 40 is fitted onto the movable sleeve 30. The movable sleeve 30 is movable along the axial direction. The movable sleeve 30 and the fixed sleeve 40 are provided coaxially. The outer diameter of the movable sleeve 30 is slightly smaller than the inner diameter of the fixed sleeve 40, so that the movable sleeve 30 is movable within the fixed sleeve 40 along the axial direction.

[0038] The fixed sleeve 40, the moving sleeve 30 and the brush head 10 are connected through a transmission structure. When the moving sleeve 30 moves along the axial direction, the moving sleeve 30 reverses the brush head 10 through the transmission structure, thereby depositing the cosmetic substance at the cosmetic outlet.

[0039] In the cosmetic tool according to the embodiment of the present invention, when it is necessary to apply a cosmetic substance with the brush head 10, the movable sleeve 30 is driven to move along the axial direction, and the axial movement of the movable sleeve 30 transmits a reversing driving force to the brush head 10 via a transmission structure, thereby reversing the brush head 10. When the brush head 10 is reversed to the cosmetic outlet of the cosmetic container 20, the brush head 10 applies the cosmetic substance at the cosmetic outlet of the cosmetic container 20. In this way, application of the cosmetic substance is achieved. After the brush head 10 applies the cosmetic substance, the movable sleeve 30 is driven to move in the reverse direction, thereby reversing the brush head 10 in the reverse direction. After the brush head 10 is reversed to a predetermined position, the cosmetic substance on the brush head 10 can be directly applied to the skin. In the cosmetic tool according to the embodiment of the present invention, application of the cosmetic substance can be realized by simply driving the movement of the movable sleeve 30 during use, and operation is simple. In addition, in this cosmetic tool, the cosmetic container 20 and the brush head 10 are integrated into one member, which is convenient when taking it out.

[0040] In another embodiment of the present invention, as shown in Figures 2, 3 and 4, a transmission structure of the cosmetic tool is provided which is a transmission mechanism 50. The fixed sleeve 40, the moving sleeve 30 and the brush head 10 are connected to each other by the transmission mechanism 50. When the moving sleeve 30 moves along the axial direction, the moving sleeve 30 reverses the brush head 10 through the transmission mechanism 50 so that the brush head 10 applies the cosmetic substance at the cosmetic outlet.

[0041] In the cosmetic tool according to the embodiment of the present invention, when it is necessary to apply a cosmetic substance to the brush head 10, the moving sleeve 30 is driven to move along the axial direction, and at the same time, the axial movement of the moving sleeve 30 provides a reverse driving force to the brush head 10 via the transmission mechanism 50 to reverse the brush head 10. When the brush head 10 is reversed to the cosmetic outlet of the cosmetic container 20, the brush head 10 applies the cosmetic substance at the cosmetic outlet of the cosmetic container 20. In this way, application of the cosmetic substance is realized. After the brush head 10 applies the cosmetic substance, the moving sleeve 30 is further moved in the reverse direction to reverse the brush head 10. When the brush head 10 is reversed to a specific position, the cosmetic substance on the brush head 10 can be applied to the skin. The cosmetic tool according to the embodiment of the present invention is easy to operate because application of the cosmetic substance can be realized by driving the movement of the moving sleeve 30 during use. Furthermore, in this cosmetic tool, the cosmetic storage section 20 and the brush head 10 are integrated into a single member, which is convenient when taking it with you when you go out.

[0042] In another embodiment of the present invention, as shown in FIG. 2, FIG. 3 and FIG. 4, a transmission mechanism 50 of a cosmetic tool is provided, which includes a rack 51 and a meshing gear 52 meshing with the rack 51. The rack 51 is provided on the inner wall of the fixed sleeve 40 and extends along the axial direction of the moving sleeve 30. The meshing gear 52 is attached to the outer wall of the moving sleeve 30 and connected to the brush head 10. When the moving sleeve 30 moves along the axial direction, the rack 51 drives the meshing gear 52 to rotate, and the meshing gear 52 drives the brush head 10 to rotate in the reverse direction. Specifically, when it is necessary to apply a cosmetic substance to the brush head 10, the meshing gear 52 is meshed with the rack 51, so that the moving sleeve 30 is driven to move toward the brush head 10, whereby the meshing gear 52 is rotated by the drive of the rack 51, and the brush head 10 is rotated in the reverse direction by the rotation of the meshing gear 52. This realizes the brush head 10 to rotate in the reverse direction to apply a cosmetic substance. By utilizing the power transmission by the meshing gear 52 and the rack 51, the reliability of the power transmission is high, and the reversal stability of the brush head 10 is high.

[0043] In another embodiment of the present invention, as shown in Figures 2, 3 and 4, a transmission mechanism 50 of a cosmetic tool is provided, which includes a plurality of transmission gears 53. The meshing gear 52 and the plurality of transmission gears 53 mesh sequentially along the axial direction of the moving sleeve 30 toward the brush head 10 along the cosmetic container 20. The outer diameters of the transmission gears 53 are all smaller than the outer diameter of the meshing gear 52. One of the transmission gears 53 is connected to the brush head 10. As can be seen, the transmission gear 53 does not mesh with the rack 51, and the meshing gear 52 meshes with the rack 51. When it is necessary to apply a cosmetic substance to the brush head 10, the transmission gear 53 passes over the rack 51 when the moving sleeve 30 moves. In this case, the meshing gear 52 does not mesh with the rack 51, the brush head 10 does not rotate, and the moving sleeve 30 continues to move to a predetermined position, that is, only when the meshing gear 52 and the rack 51 mesh with each other can the moving sleeve 30 drive the meshing gear to rotate. In the process of rotating the meshing gear 52, the transmission gear 53 is rotated, and the rotating transmission gear 53 rotates the brush head 10. This realizes the brush head 10 to rotate and apply the cosmetic substance. In this process, the moving sleeve 30 does not drive the brush head 10 to rotate and move a certain distance, and the moving sleeve 30 exposes the brush head 10 from the fixed sleeve 40 and allows it to move a certain distance. In this way, the brush head 10 rotates outside the fixed sleeve 40. The rotation of the brush head 10 does not interfere with the fixed sleeve 40.

[0044] In the embodiment, the number of the transmission gears 53 may be one, two, three or more. The number of the transmission gears 53 can be selected according to actual needs, and although not limited here, the number of the transmission gears 53 is illustratively four.

[0045] In another embodiment of the present invention, as shown in Fig. 4, Fig. 5 and Fig. 6, the brush head 10 of the cosmetic tool provided includes a brush head holder 11 and an attachment tool 12 for applying a cosmetic substance. A connecting post 111 is provided on the outer peripheral wall of the brush head holder 11. A connecting hole 321 is provided on the inner wall of the moving sleeve 30. The connecting post 111 passes through the connecting hole 321 and is connected to the transmission gear 53. Specifically, the rotation of the transmission gear 53 causes the connecting post 111 to rotate in the connecting hole 321, and the rotation of the connecting post 111 causes the brush head holder 11 to rotate in reverse, causing the attachment tool 12 to rotate toward the cosmetic storage part 20. When the attachment tool 12 rotates to the cosmetic outlet, the attachment tool 12 applies the cosmetic substance at the cosmetic outlet. In this way, application of the cosmetic substance is realized.

[0046] In another embodiment of the present invention, as shown in Figs. 4, 5 and 6, the brush head 10 of the provided cosmetic tool further includes a first elastic member 13 and a connecting shaft 14. The brush head holder 11 has an open-shaped mounting cavity 112. The attachment 12 is attached to the opening of the mounting cavity 112 so as to cover it. Specifically, the attachment 12 includes a fixing plate 121 and an attachment part 122 fixed to the fixing plate 121. The fixing plate 121 is provided to cover the opening of the mounting cavity 112, and seals the opening of the mounting cavity 112 to prevent the cosmetic substance from entering the mounting cavity 112 and interfering with the movement of the connecting shaft 14 and the first elastic member 13. Here, the attachment part 122 may be a brush, an egg-shaped sponge, a sponge block, or other member that can be used to attach the cosmetic substance and apply the cosmetic substance to the skin.

[0047] In the embodiment, the brush head holder 11 has a rotation hole 113 communicating with the mounting cavity 112. The rotation hole 113 is arranged opposite to the connecting post 111. The connecting shaft 14 is inserted into the mounting cavity 112 through the rotation hole 113. The end of the connecting shaft 14 facing the rotation hole 113 is fixedly connected to the moving sleeve 30. As can be seen, the inner wall of the mounting cavity has a fixing hole 116. The fixing hole 116 faces the rotation hole 113. The fixing hole 116, the rotation hole 113 and the connecting post 111 are arranged coaxially. Both ends of the connecting shaft 14 are respectively inserted into the fixing hole 116 and the rotation hole 113, and the inner diameters of the fixing hole 116 and the rotation hole 113 are slightly larger than the outer diameter of the connecting shaft 14. In this way, when the brush head holder 11 rotates by being driven by the connecting pillar 111, the brush head holder 11 can rotate around the axis of the connecting shaft 14. Since the opposing sides of the brush head holder 11 are supported by the connecting pillar 111 and the connecting shaft 14, respectively, the rotation stability of the brush head holder 11 is high. A long plate 141 is provided at the end of the connecting shaft 14. A long hole 323 is opened in the outer wall of the moving sleeve 30. The long plate 141 is fitted and fixed in the long hole 323. This realizes a fixed connection between the connecting shaft 14 and the moving sleeve 30. In addition, when mounting, the end of the connecting shaft 14 enters the moving sleeve 30 through the long hole 323, and then penetrates the rotation hole 113 and is inserted into the mounting cavity 112 and then inserted into the fixing hole 116. This makes it easy to mount the connecting shaft 14 and has high structural reliability.

[0048] In the embodiment, the first elastic member 13 is fitted onto the connecting shaft 14. The end of the connecting shaft 14 facing away from the rotation hole 113 is connected to one end of the first elastic member 13, and the other end of the first elastic member 13 is connected to the brush head holder 11. The first elastic member 13 is provided so that the attachment tool 12 faces away from the cosmetic storage part 20 by reversing the brush head holder 11 in the opposite direction. Specifically, when the attachment tool 12 is reversed toward the cosmetic outlet, the brush head holder 11 rotates to twist the first elastic member 13. After the attachment tool 12 applies the cosmetic material, the brush head holder 11 automatically reverses the brush head holder 11 and the attachment tool 12 to their original positions under the recovery action of the first elastic member 13. That is, the first elastic member 13 ensures that the brush head 10 can automatically return to its original position after applying the cosmetic material, which is convenient for the subsequent application of the cosmetic material.

[0049] In the embodiment, the first elastic member 13 is an elastic member such as a spring. When the first elastic member 13 is a spring, a fixing groove 142 is formed on the end face of the connecting shaft 14, and one end of the spring is hung in the fixing groove 142. A hanging structure is provided on the cavity wall of the mounting cavity 112. The other end of the spring is hung on the hanging structure. In this way, the spring is fixedly attached.

[0050] In another embodiment of the present invention, as shown in Figures 4, 5 and 6, the cosmetic material applicator 12 and the brush head holder 11 are removably connected. Specifically, the fixing plate 121 and the brush head holder 11 are removably connected, that is, the applicator 12 can be removed from the brush head holder 11 and replaced, and different types of applicators 12 can be replaced to meet different cosmetic needs, which improves the versatility and application range of the cosmetic tool, and also makes it convenient to clean the applicator 12.

[0051] In the embodiment, the fixed plate 121 is provided with a locking protrusion 1211, and the brush head holder 11 is provided with a locking groove 115 that is engaged with the locking protrusion 1211. The brush head holder 11 and the fixed plate 121 are connected by the engagement of the locking protrusion 1211 and the locking groove 115, so that the fixed plate 121 can be removed from the brush head holder 11, and the fixed plate 121 can be easily replaced. The brush head holder 11 is columnar, and an attachment cavity 112 is opened on the end face of the brush head holder 11, and the locking groove 115 is provided on the inner wall of the attachment cavity 112. The fixed plate 121 is plate-shaped, and the attachment portion 122 and the locking protrusion 1211 are provided on both opposing sides of the fixed plate 121, respectively. The locking protrusion 1211 includes a horizontal portion and a vertical portion. One end of the horizontal part is connected vertically to the fixing plate 121, and the other end of the horizontal part is connected to the vertical part. The locking groove 115 includes an axial part and a circumferential part, the axial part extends along the axis of the mounting cavity 112, and the circumferential part extends along the circumferential direction of the mounting cavity 112. As a result, when the attachment tool 12 is attached to the brush head holder 11, the end of the vertical part is first inserted into the axial part, and then moved along the axial direction. After the vertical part moves to the end of the axial part, the fixing plate 121 is rotated to lock the vertical part into the circumferential part. In this way, the fixing plate 121 is fixed to the brush head holder 11. When the attachment tool 12 is to be replaced, the fixing plate 121 is rotated in the reverse direction so that the end of the vertical part rotates to the connection point between the circumferential part and the axial part, and then the end of the vertical part is taken out along the axial part.

[0052] In the embodiment, the number of the locking protrusions 1211 may be two, three, four or more. The locking protrusions 1211 are provided at intervals along the circumferential direction of the fixed plate 121. The locking protrusions 1211 and the locking grooves 115 are provided in one-to-one correspondence. By providing a plurality of locking protrusions 1211, the connection between the fixed plate 121 and the brush head holder 11 is highly reliable. In terms of processing, manufacturing and structural strength, it is preferable that there are two locking protrusions 1211, which are located on opposite sides of the moving sleeve 30.

[0053] In another embodiment, the fixing plate 121 may be fixedly connected to the brush head holder 11. For example, the fixing plate 121 and the brush head holder 11 are integrally injection molded or 3D printed, or the fixing plate 121 and the brush head holder 11 are connected by welding. In this way, the fixing plate 121 and the brush head holder 11 are not removable, and the attachment 12 cannot be replaced.

[0054] In another embodiment of the present invention, as shown in Fig. 4, Fig. 5 and Fig. 6, the outer peripheral wall of the brush head holder 11 of the provided cosmetic tool is provided with a semicircular groove 114 centered on the rotation axis around which the brush head holder 11 rotates, and the inner wall of the moving sleeve 30 is provided with a position regulating post 322. The position regulating post 322 is inserted into the semicircular groove 114 and can move in the semicircular groove 114 with the rotation of the brush head holder 11 to limit the reversal angle of the brush head holder 11. In the process of the rotation of the brush head holder 11, the position regulating post 322 moves along the semicircular groove 114. When the position regulating post 322 moves to both ends of the semicircular groove 114, the position regulating post 322 cannot continue to move in the semicircular groove 114, and the brush head holder 11 cannot continue to rotate. In this way, the limit of the reversal angle of the brush head 10 is achieved. In a specific use, when the position regulating post 322 is located at one end of the semicircular groove 114, the applicator 12 is provided facing away from the cosmetic storage unit 20. In this case, the applicator 12 can apply the cosmetic substance on the applicator 12 to the skin. When the position regulating post 322 moves along the semicircular groove 114 to the other end of the semicircular groove 114, the applicator 12 faces the cosmetic outlet and applies the cosmetic substance at the cosmetic outlet. In this way, the position regulating post 322 cooperates with the semicircular groove 114 to allow the brush head 10 to stay accurately at the cosmetic outlet and apply the cosmetic substance.

[0055] In the embodiment, the moving sleeve 30 includes a sleeve body 31 and moving arms 32 provided on both sides of the sleeve body 31. The brush head 10 is located between the two moving arms 32, and the connection hole 321 and the position regulating post 322 are provided on the same moving arm 32. The other moving arm 32 is provided with a long hole 323. The gap formed between the two moving arms 32 can provide a reversing space for the reversing of the brush head 10, so that the reversing of the brush head 10 is smoother and more reliable. The sleeve body 31 and the moving arm 32 are both provided with an assembly post 33 on their outer surfaces. The meshing gear 52 and the transmission gear 53 are rotatably attached to the assembly post 33 in one-to-one correspondence, respectively. In addition, after the brush head 10 has applied cosmetic substance and been turned over, the transmission gear 53 does not mesh with the rack 51, so that the movable sleeve 30 retreats a certain distance into the fixed sleeve 40 and the brush head 10 does not reverse. In this case, the movable arm 32 retreats into the fixed sleeve 40 accordingly, so that the movable arm 32 is not exposed from the fixed sleeve 40 and the overall appearance of the cosmetic tool is improved.

[0056] In another embodiment of the present invention, the inner wall of the movable sleeve 30 of the brush head holder 11 of the cosmetic tool is provided with a semicircular groove 114 centered on the rotation axis around which the brush head holder 11 rotates, and the outer peripheral wall of the brush head holder 11 is provided with a position regulating post 322. The position regulating post 322 is inserted into the semicircular groove 114 and can move within the semicircular groove 114 as the brush head holder 11 rotates to limit the reversal angle of the brush head holder 11. During the process of the brush head holder 11 rotating, the position regulating post 322 moves along the semicircular groove 114, and when the position regulating post 322 moves to both ends of the semicircular groove 114, the position regulating post 322 cannot continue to move within the semicircular groove 114, so that the brush head holder 11 can continue to rotate. This realizes the limit of the reversal angle of the brush head 10. In a specific use, when the position regulating post 322 is located at one end of the semicircular groove 114, the applicator 12 is placed facing away from the cosmetic container 20. In this case, the applicator 12 can apply the cosmetic substance on the applicator 12 to the skin. When the position regulating post 322 moves along the semicircular groove 114 to the other end of the semicircular groove 114, the applicator 12 faces the cosmetic outlet and applies the cosmetic substance at the cosmetic outlet. In this way, the position regulating post 322 cooperates with the semicircular groove 114 to allow the brush head 10 to stay accurately at the cosmetic outlet to achieve application of the cosmetic substance.

[0057] In another embodiment of the present invention, as shown in Figs. 2 and 3, a guide groove 411 extending along the axial direction is formed on the inner wall of the fixed sleeve 40 of the provided cosmetic tool, and a guide protrusion 311 is provided on the outer circumferential wall of the movable sleeve 30. The guide protrusion 311 is inserted into the guide groove 411. Specifically, the guide protrusion 311 is provided on the outer periphery of the sleeve body 31, and the movable sleeve 30 has high movement stability along the axis of the movable sleeve 30 due to the engagement between the guide protrusion 311 and the guide groove 411. In addition, due to the position restriction by the guide protrusion 311 and the guide groove 411, the movable sleeve 30 cannot rotate along the circumferential direction relative to the fixed sleeve 40, so that the meshing gear 52 can stably mesh with the rack 51.

[0058] In an embodiment, the guide grooves 411 are provided corresponding to the guide protrusions 311. The number of the guide protrusions 311 may be two, three, or four or more. The guide protrusions 311 are provided at intervals along the circumferential direction of the moving sleeve 30. Illustratively, the number of the guide protrusions 311 is two.

[0059] In another embodiment of the present invention, a cosmetic tool is provided in which an inner wall of the fixed sleeve 40 is provided with a guide groove 411 extending along the axial direction, and an inner wall of the movable sleeve 30 is provided with a guide protrusion 311. Specifically, the guide groove 411 is provided on the outer periphery of the sleeve body 31. Due to cooperation between the guide protrusion 311 and the guide groove 411, the movable sleeve 30 has high stability in moving along the axis of the movable sleeve 30. In addition, due to the position restriction imposed by the guide protrusion 311 and the guide groove 411, the movable sleeve 30 cannot rotate along the circumferential direction relative to the fixed sleeve 40, so that the meshing gear 52 can stably mesh with the rack 51.

[0060] In another embodiment of the present invention, as shown in Fig. 2 and Fig. 3, the cosmetic tool of the provided cosmetic tool further includes a second elastic member 60. The second elastic member 60 is located in the guide groove 411, one end of the second elastic member 60 is connected to the fixed sleeve 40, and the other end of the second elastic member 60 is connected to the guide protrusion 311. The second elastic member 60 is for driving the moving tool to move backwards against the brush head 10. Specifically, when the moving sleeve 30 is pushed toward the brush head 10, the second elastic member 60 is pulled, and when the moving sleeve 30 reaches a predetermined position, that is, after the brush head 10 applies the cosmetic substance, the second elastic member 60 moves the moving sleeve 30 in the opposite direction under the action of its own restoring force, thereby realizing the automatic return of the moving sleeve 30, which makes the use of the cosmetic tool simple and convenient. The second elastic member 60 is a member having elasticity such as a spring.

[0061] In the embodiment, a hook protrusion 412 is provided at the upper end of the guide groove 411, and both ends of the elastic member are respectively hooked between the hook protrusion 412 and the guide protrusion 311, thereby realizing the fixing of the elastic member.

[0062] In the embodiment, the fixed sleeve 40 includes two semi-circular plates 41. The two semi-circular plates 41 are joined together to form the fixed sleeve 40. The fixed sleeve 40 is divided, which makes it convenient to install and arrange the transmission mechanism 50 and the moving sleeve 30.

[0063] In another embodiment of the present invention, the cosmetic container 20 of the provided cosmetic tool is removably connected to the moving sleeve 30, which makes it convenient to replace the cosmetic container 20.

[0064] In the embodiment, as shown in Figs. 1, 2 and 3, the cosmetic storage unit 20 is directly inserted into the sleeve body 31, and a convex side is provided at the end of the sleeve body 31 facing the moving arm 32, and a concave side 21 is provided at the end of the cosmetic storage unit 20. After the cosmetic storage unit 20 is inserted into the sleeve body 31 and reaches a predetermined position, the convex side is engaged with the concave side 21, so that the cosmetic storage unit 20 cannot escape from the sleeve body 31 to the opening of the moving arm 32. This cosmetic tool further includes a cosmetic storage unit lid 72. The cosmetic storage unit lid 72 is spirally connected to the end of the sleeve body 31 facing away from the moving arm 32, thereby preventing the cosmetic storage unit 20 from coming out of the movable sleeve body 30. In addition, a handle 22 is provided on the end face of the cosmetic storage unit 20 facing away from the cosmetic outlet. The handle 22 is exposed from the movable sleeve body 30 and abuts against the cosmetic storage unit lid 72, and the other end of the cosmetic storage unit 20 abuts against the convex side. This achieves axial fixation of the cosmetic storage unit 20 in the sleeve body 31, and the fixing structure is simple and easy to manufacture. In addition, since the handle 22 is exposed from the movable sleeve body 30, when replacing the cosmetic storage unit 20, the cosmetic storage unit 20 can be pulled out from the sleeve body 31 by directly pulling it, achieving the movable replacement of the cosmetic storage unit 20, and the structure is designed in an intricate manner, making it more convenient to use the cosmetic tool. An outer lid is further fitted onto the cosmetic storage unit lid 72. The outer lid is an aluminum alloy outer lid, a plastic outer lid, an iron outer lid, or an outer lid made of other materials, which improves the aesthetic appearance of the cosmetic tool.

[0065] In another embodiment of the present invention, the cosmetic container 20 of the cosmetic tool provided may be fixedly connected to the moving sleeve 30. For example, the cosmetic container 20 and the sleeve body 31 are integrally injection molded or 3D printed, or the cosmetic container 20 and the sleeve body 31 are connected by welding. In this way, the cosmetic container 20 and the sleeve body 31 are not detachable, and the cosmetic container 20 cannot be replaced.

[0066] 1 and 2, an outer shell 71 is fitted onto the fixing sleeve 40, and the outer shell 71 can improve the aesthetic appearance of the cosmetic tool. For example, the outer shell 71 may be a metal outer shell or a plastic outer shell, such as an aluminum outer shell, an iron outer shell, a silica gel outer shell, etc.

[0067] 1 and 2, in an embodiment, the cosmetic tool further includes a brush head cover 73. The brush head cover 73 is disposed on the brush head 10 to cover the brush head 10, and is engaged and connected to the fixed sleeve 40. The brush head cover 73 prevents the brush head 10 from being exposed to the outside, and the brush head 10 is located in a sealed environment, which makes the brush head 10 more clean and safer to use.

[0068] As shown in Figures 7 to 16, in another embodiment of the present invention, as shown in Figures 7 to 9, a cosmetic tool is provided, which includes a brush head 10, a cosmetic container 20, a movable sleeve 30, and a fixed sleeve 40. The brush head 10 can be loaded with a cosmetic substance and applied to the skin of a user.

[0069] The cosmetic container 20 is for containing cosmetic materials. There is a cavity in the cosmetic container 20. The cavity can contain cosmetic materials. The cosmetic materials can be blush, liquid, lipstick, highlighter, and other types of cosmetic materials.

[0070] The cosmetic storage unit 20 is attached inside the movable sleeve 30. The brush head 10 is rotatably connected to one end of the movable sleeve 30 and is provided facing the cosmetic storage unit 20. A cosmetic outlet is opened on the end surface of the cosmetic storage unit 20 facing the brush head 10, through which the brush head 10 applies a cosmetic substance. The brush head 10 is provided with an attachment tool 130 that can apply a cosmetic substance to the skin. When it is not necessary to apply a cosmetic substance to the brush head 10, the attachment tool 130 is exposed from the movable sleeve 30, and application of the cosmetic substance is realized. When it is necessary to apply a cosmetic substance to the brush head 10 at the cosmetic outlet of the cosmetic storage unit 20, the brush head 10 is turned 180° toward the cosmetic storage unit 20, and the attachment tool 130 is turned inside the movable sleeve 30 to apply the cosmetic substance at the cosmetic outlet of the cosmetic storage unit 20. Specifically, the cosmetic container 20 and the brush head 10 are spaced apart from one another along the axial direction of the movable sleeve 30. The cosmetic outlet on the cosmetic container 20 communicates with the cavity, and the cosmetic can be exposed from the cosmetic outlet, which is convenient for application with the application tool 130. The application tool 130 may be a brush, an egg-shaped sponge or a sponge puff, and other members capable of applying the cosmetic, and is not particularly limited.

[0071] The fixed sleeve 40 is fitted on the movable sleeve 30. The movable sleeve 30 is movable along the axial direction. As can be understood, the fixed sleeve 40 is fitted on the movable sleeve 30, and the outer diameter of the movable sleeve 30 is smaller than the inner diameter of the fixed sleeve 40. This allows the movable sleeve 30 to slide along the axial direction. An outer shell 500 is further fitted on the fixed sleeve 40. The outer shell 500 is an aluminum alloy outer shell 500, a plastic outer shell 500, an iron outer shell 500, or an outer shell 500 made of other materials, which improves the aesthetic appearance of the cosmetic tool. The movable sleeve 30 and the fixed sleeve 40 may be a rectangular sleeve, a circular sleeve, an elliptical sleeve, or other shapes of hollow columnar structures, and are not particularly limited.

[0072] The brush head 10 is provided with a connecting shaft 14. The rotation structure includes a semicircular hole 3210 and a position restricting groove 421. The semicircular hole 3210 is provided on the inner wall of the moving sleeve 30 and is centered on the rotation axis of the brush head 10. A straight line connecting both ends of the semicircular hole 3210 is parallel to the axial direction of the moving sleeve 30. The position restricting groove 421 is provided on the inner wall of the fixed sleeve 40 and is perpendicular to the axial direction of the moving sleeve 30. The end of the connecting shaft 14 is inserted into the semicircular hole 3210 and the position restricting groove 421. The position restricting groove 421 may be a straight groove or an arc groove extending along the circumferential direction of the fixed sleeve 40.

[0073] The cosmetic tool according to the embodiment of the present invention will be further described below. In this cosmetic tool, the end of the connecting shaft 14 on the brush head 10 is provided through the semicircular hole 3210 and the position restricting groove 421, the position restricting groove 421 is perpendicular to the axial direction of the moving sleeve 30, the semicircular hole 3210 is centered on the rotation axis of the brush head 10, and the straight line connecting both ends of the semicircular hole 3210 is parallel to the axial direction of the moving sleeve 30. In this way, when it is necessary to apply a cosmetic substance at the cosmetic outlet of the cosmetic storage part 20 to the brush head 10, the moving sleeve 30 is pushed and moved toward the brush head 10 along the axial direction, thereby realizing the reversal and application of the brush head 10. In this process, the connecting shaft 14 on the brush head 10 is subjected to the position restricting action of the position restricting groove 421, so that the brush head 10 does not move along the axial direction of the moving sleeve 30. Furthermore, the connecting shaft 14 on the brush head 10 is driven by the semicircular hole 3210 to move from one end to the other along the semicircular hole 3210, thereby turning the brush head 10 over with respect to the movable sleeve 30. After turning over, the brush head 10 applies the cosmetic substance at the cosmetic outlet of the cosmetic container 20. This allows the brush head 10 to apply the cosmetic substance. In the cosmetic tool according to the embodiment of the present invention, the turning over of the brush head 10 is achieved by the mutual connection and cooperation of the connecting shaft 14 on the brush head 10, the semicircular hole 3210 on the movable sleeve 30, and the position regulating groove 421 on the fixed sleeve 40, which results in a simple structure, convenient manufacture, fewer cosmetic tool parts, simple transmission, high usage reliability, and long service life.

[0074] The cosmetic tool of the embodiment of the present invention is easy to operate because, when in use, application of cosmetic material can be achieved simply by driving the movement of the movable sleeve 30. In addition, the cosmetic storage section 20 and the brush head 10 are integrated into a single component, making it convenient to take with you when you go out.

[0075] In another embodiment of the present invention, as shown in Figures 9, 10 and 15, the inner wall of the moving sleeve 30 of the provided cosmetic tool is provided with a rotating post 3220, the peripheral wall of the brush head 10 is provided with a rotating groove 1140, and the rotating post 3220 is rotatably connected in the rotating groove 1140. Specifically, the rotating post 3220 is inserted into the rotating groove 1140 and can rotate in the rotating groove 1140, and the rotating post 3220 is parallel to and spaced apart from the connecting shaft 14, and the rotating connection between the brush head 10 and the moving sleeve 30 is realized by the rotatable engagement between the rotating post 3220 and the rotating groove 1140, which has a simple structure and is convenient for processing and manufacturing.

[0076] In another embodiment of the present invention, a rotating groove 1140 is provided on the inner wall of the moving sleeve 30 of the cosmetic tool, and a rotating post 3220 is provided on the peripheral wall of the brush head 10, and the rotating post 3220 is rotatably connected in the rotating groove 1140. Specifically, the rotating post 3220 is inserted into the rotating groove 1140 and can rotate in the rotating groove 1140, and the rotating post 3220 and the connecting shaft 14 are arranged in parallel and spaced apart along the axial direction of the moving sleeve 30. The rotating connection between the brush head 10 and the moving sleeve 30 is realized by the rotatable engagement between the rotating post 3220 and the rotating groove 1140, which has a simple structure and is convenient for processing and manufacturing.

[0077] In another embodiment of the present invention, as shown in Fig. 9, Fig. 10 and Fig. 15, the rotation groove 1140 of the provided cosmetic tool is an elongated groove. The elongated groove is parallel to the axial direction of the movable sleeve 30. A straight hole 3230 is further provided on the inner wall of the movable sleeve 30. The straight hole 3230 communicates with an end of the semicircular hole 3210 and extends in the axial direction of the movable sleeve 30 facing away from the semicircular hole 3210. Specifically, the straight hole 3230 may be located between the semicircular hole 3210 and the cosmetic storage unit 20, or may be located on the side of the semicircular hole 3210 facing away from the cosmetic storage unit 20. When the straight hole 3230 is located between the semicircular hole 3210 and the cosmetic storage section 20 and the moving sleeve 30 moves to rotate the brush head 10 180° to deposit the cosmetic material, the rotating column 3220 continues to move along the long groove, and the connecting shaft 14 also continues to move along the straight hole 3230, so that the moving sleeve 30 can continue to move along the axial direction, thereby allowing the brush head 10 to continue to move toward the cosmetic outlet of the cosmetic storage section 20. In this way, the amount of cosmetic material applied to the brush head 10 can be controlled by controlling the moving distance of the moving sleeve 30. When the moving sleeve 30 continues to move a long distance, the pressure of the brush head 10 against the cosmetic outlet is large, so that more cosmetic material is applied to the brush head 10. When the moving sleeve 30 continues to move a short distance, the pressure of the brush head 10 against the cosmetic outlet is small, so that less cosmetic material is applied to the brush head 10. When the straight hole 3230 is located at the side of the semicircular hole 3210 facing away from the cosmetic container 20 and the movable sleeve 30 turns the brush head 10 180° in the opposite direction, the brush head 10 is exposed from the movable sleeve 30, and the rotating post 3220 can continue to move along the long groove and the connecting shaft 14 can also continue to move along the straight hole 3230, so that the movable sleeve 30 can continue to move along the axial direction and the brush head 10 can continue to move out of the movable sleeve 30. In this way, the exposed portion of the attachment 130 of the brush head 10 is gradually increased, which is convenient for applying the cosmetic material.In addition, during the process of applying the cosmetic substance, the moving sleeve 30, the fixed sleeve 40 and other components will not scratch the skin, which improves the comfort of the user when applying the cosmetic substance. After the rotating column 3220 enters the long groove and the connecting shaft 14 also enters the straight hole 3230, the brush head 10 will not turn over when applying the cosmetic substance, which makes it easier for the brush head 10 to apply the cosmetic substance.

[0078] In another embodiment of the present invention, as shown in Figures 9, 10 and 15, both ends of the semicircular hole 3210 of the provided cosmetic tool are connected to straight holes 3230. Specifically, the number of straight holes 3230 is two. One straight hole 3230 may be located between the semicircular hole 3210 and the cosmetic storage part 20, and the other straight hole 3230 may be located on the side of the semicircular hole 3210 facing away from the cosmetic storage part 20. As can be seen from the above analysis, this cosmetic tool can adjust the amount of cosmetic material applied by the brush head 10, and the brush head 10 does not turn over during the process of applying the cosmetic material to the skin, making it easier for the brush head 10 to apply the cosmetic material.

[0079] In another embodiment of the present invention, as shown in Fig. 10 and Fig. 11, the movable sleeve 30 of the provided cosmetic tool includes a movable sleeve body 310 and two movable arms 32. The two movable arms 32 are respectively connected to two opposite sides of the movable sleeve body 310 and extend back to the movable sleeve body 310 along the axial direction of the movable sleeve body 310. The cosmetic container 20 is mounted in the movable sleeve body 310, and the brush head 10 is rotatably connected between the two movable arms 32. The two movable arms 32 each have a semicircular hole 3210. Both ends of the connecting shaft 14 are inserted into the two semicircular holes 3210, respectively. Specifically, the movable sleeve body 310 is the mounting base of the cosmetic container 20, and the movable arms 32 are the mounting base of the brush head 10, and the gap formed between the two movable arms 32 can provide a reversing space for the reversing of the brush head 10, so that the reversing of the brush head 10 is smooth and reliable. In addition, both ends of the connecting shaft 14 are inserted into and connected to the semicircular holes 3210 of the two moving arms 32, respectively, so that the connection reliability between the brush head 10 and the moving sleeve 30 is higher, and the reliability and stability of the inversion of the brush head 10 is improved. In order to improve the reliability and stability of the inversion of the brush head 10, a rotating post 3220 is provided on each of the two moving arms 32. A rotating groove 1140 is provided on each of the opposing sides of the brush head 10, and the two rotating posts 3220 are rotatably connected in the rotating groove 1140.

[0080] In another embodiment of the present invention, as shown in Fig. 10 and Fig. 11, the distance between the two moving arms 32 of the provided cosmetic tool is smaller than the outer diameter of the cosmetic accommodating part 20, the outer diameter of the cosmetic accommodating part 20 is smaller than the inner diameter of the movable sleeve body 310, and the outer diameter of the cosmetic accommodating part 20 is smaller than the inner diameter of the movable sleeve body 310. In this way, it can be ensured that the cosmetic accommodating part 20 is smoothly inserted and installed in the movable sleeve body 310. In addition, since the distance between the two moving arms 32 is smaller than the outer diameter of the cosmetic accommodating part 20, the distance between the opposing side surfaces of the two moving arms 32 is also smaller than the inner diameter of the movable sleeve body 310. In this way, after the cosmetic accommodating part 20 is inserted into the movable sleeve body 310, the movable sleeve body 310 can abut against the end surface of the movable arm 32 close to the movable sleeve body 310, and the axial positioning of the movable sleeve body 310 is realized.

[0081] In another embodiment of the present invention, as shown in Fig. 12 and Fig. 13, the fixed sleeve 40 of the cosmetic tool provided includes a fixed sleeve body 410 and two fixed arms 42. The two fixed arms 42 are respectively connected to opposite sides of the fixed sleeve body 410 and extend back to the fixed sleeve body 410 along the axial direction of the fixed sleeve 40. The fixed sleeve body 410 is fitted onto the movable sleeve 30, and the two movable arms 32 are both provided with position restriction grooves 421. Both ends of the connecting shaft 14 are respectively inserted into the two position restriction grooves 421. Specifically, the fixed sleeve body 410 is fitted onto the movable sleeve body 310, and the gap formed between the two fixed arms 42 can provide a reversing space for the reversing of the brush head 10, so that the reversing of the brush head 10 is smoother and more reliable. In addition, since both ends of the connecting shaft 14 are inserted into the two position regulating grooves 421, respectively, the connection between the brush head 10 and the fixed sleeve 40 is reliable, and the reliability and stability of the inversion of the brush head 10 is improved.

[0082] In the embodiment, the length of the fixed sleeve body 410 is longer than that of the moving sleeve body 310. The fixed sleeve body 410 can cover a part of the moving arm 32, so that the overall appearance of the cosmetic tool is improved.
