[0044] Conventional cosmetic brushes are generally designed as single-function brush tools, requiring separate use in conjunction with an independent powder container or compact powder case. During the powder uptake process, a user must first open the powder container and then dip the brush head into the powder material to take up the powder. This process readily causes the powder to scatter and become wasted, while the amount of powder taken up is difficult to precisely control, thereby adversely affecting the makeup application effect and efficiency.

[0045] Furthermore, repeated opening and closing of the powder container not only renders the operation cumbersome, but also increases the risk of contamination of the powder material, compromising hygiene during use.

[0046] In outdoor makeup touch-up scenarios, the combination of a separate powder container or compact with a separate cosmetic brush exhibits poor convenience and fails to meet the requirements of modern fast-paced lifestyles that demand high portability and ease of use.

[0047] In order to solve the aforementioned problems, the present disclosure provides a cosmetic brush.

[0048] Reference is made to FIG. 1 to FIG. 6. In one embodiment of the present disclosure, the cosmetic brush comprises an outer shell 1, a powder storage container 2, a powder guiding assembly 3, and a brush body 5.

[0049] The outer shell 1 is hollow inside. The powder storage container 2 is connected to a lower end of the outer shell 1. The powder storage container 2 is configured to contain cosmetic powder. The powder guiding assembly 3 is disposed inside the outer shell 1. A powder guiding channel 4 is formed inside the powder guiding assembly 3. An upper portion of the powder guiding channel 4 is provided with an opening, and a lower portion of the powder guiding channel 4 is in communication with the powder storage container 2. The brush body 5 is accommodated in an upper portion of the outer shell 1 and covers the opening of the powder guiding channel 4. the powder guiding channel 4 is configured such that, when the outer shell 1 is inverted, the cosmetic powder inside the powder storage container 2 can be conveyed through the powder guiding channel 4 and adhered to the brush body 5.

[0050] In the above structure, by integrally combining the outer shell 1, the powder storage container 2, the powder guiding assembly 3 and the brush body 5, an integrated design of the cosmetic brush and powder storage function is achieved, eliminating the need to additionally carry a separate powder container. Thereby significantly improving the convenience and portability of the makeup application operation.

[0051] The arrangement of the powder guiding channel 4 precisely matches the usage scenario in which the outer shell 1 is inverted, enabling the cosmetic powder inside the powder storage container 2 to be stably delivered to the brush body 5 under the action of gravity and adhered thereto without requiring manual dipping of the powder. Thereby avoiding waste caused by scattering of the powder while ensuring uniform powder uptake by the brush body 5, thus enhancing both the makeup application effect and efficiency.

[0052] The hollow interior of the outer shell 1 not only provides a stable installation space for the powder guiding assembly 3, but also serves a protective function for the internal powder guiding channel 4 and the brush body 5, reducing contamination by external dust and prolonging the service life of the product.

[0053] In one embodiment, the powder guiding assembly 3 includes a mounting base 31 fixed inside the outer shell 1. The brush body 5 is mounted on an upper portion of the mounting base 31, the powder guiding channel 4 extends through both upper and lower ends of the mounting base 31 in the vertical direction, and the upper opening of the powder guiding channel 4 faces toward the brush body 5.

[0054] In the above structure, the powder guiding assembly 3 is provided with the mounting base 31 fixed inside the outer shell 1, thereby providing a stable mounting carrier for the brush body 5, preventing the brush body 5 from loosening or shifting during use, ensuring precise alignment between the brush body 5 and the upper opening of the powder guiding channel 4, and guaranteeing smooth powder feeding.

[0055] the powder guiding channel 4 penetrates both the upper and lower ends of the mounting base 31 with its upper opening facing the brush body 5. Thereby shortening the powder feeding path, reducing powder residue during transportation, further improving powder utilization efficiency. While enabling the mounting base 31 to simultaneously perform the dual functions of mounting / fixing and powder guiding / orientation, simplifying the overall structure of the product and reducing production and assembly difficulty as well as cost.

[0056] In one embodiment, the powder guiding assembly 3 further includes a locking component 32. A powder passing channel 41 is formed inside the mounting base 31, the powder passing channel 41 extends through both upper and lower ends of the mounting base 31 in the vertical direction. The upper opening of the powder passing channel 41 faces toward the brush body 5, the locking component 32 is disposed inside the powder passing channel 41. An upper portion of the locking component 32 forms a powder feeding portion 321 extending into the powder passing channel 41. A powder feeding channel 42 is formed inside the powder feeding portion 321. An upper end of the powder feeding channel 42 is in communication with the corresponding powder passing channel 41. A lower portion of the locking component 32 forms a connecting portion 322 configured for detachable connection with the powder storage container 2.

[0057] In the above structure, the powder passing channel 41 is additionally provided inside the mounting base 31. the powder passing channel 41 cooperates with the powder feeding portion 321 and the powder feeding channel 42 of the locking component 32, so as to achieve precise splitting and guiding of the powder feeding path, ensuring uniform and stable delivery of powder to the brush body 5 and avoiding localized powder accumulation or uneven powder feeding.

[0058] The connecting portion 322 of the locking component 32 enables detachable connection between the powder storage container 2 and the mounting base 31, facilitating subsequent disassembly, cleaning and powder replenishment of the powder storage container 2, thereby improving practicality and maintainability of the product. The corresponding communication design between the powder feeding channel 42 and the powder passing channel 41 further optimizes the sealing performance of the powder guiding assembly 3, reduces powder leakage during delivery, and simultaneously enhances overall stability of the powder guiding assembly 3.

[0059] In one embodiment, an upper end of the powder feeding portion 321 is a closed end 3211, and the powder feeding channel 42 communicates with the corresponding powder passing channel 41 through a powder outlet hole 3212 provided in the closed end 3211.

[0060] In the above structure, the upper end of the powder feeding portion 321 is configured as the closed end 3211. The communication between the powder feeding channel 42 and the corresponding powder passing channel 41 is achieved via the powder outlet hole 3212, which can effectively control the amount of powder discharged. Thus, preventing excessive powder outflow and waste that would otherwise occur if the powder feeding channel 42 was directly through, while also preventing external impurities from entering the powder storage container 2 through the powder feeding channel 42 and contaminating the powder.

[0061] The closed end 3211 further enhances the structural strength of the powder feeding portion 321, preventing deformation of the powder feeding channel 42 due to external force compression, thereby ensuring stable realization of the powder guiding function.

[0062] In one embodiment, the upper portion of the mounting base 31 extends upwards to form a powder outlet column 311. An inner cavity of the powder outlet column 311 constitutes an upper portion of the powder passing channel 41, and an upper-end opening of the powder outlet column 311 constitutes the upper opening of the powder guiding channel 4.

[0063] In the above structure, the powder outlet column 311 is formed by upward extension at the position on the upper portion of the mounting base 31 corresponding to the powder outlet hole 3212, with its inner cavity forming the upper portion of the powder passing channel 41. Thereby making the powder feeding path more concentrated and precise and further reducing powder residue in the upper portion of the powder passing channel 41.

[0064] The upper-end opening of the powder outlet column 311 constitutes the upper opening of the powder guiding channel 4, enabling direct guiding of powder to a core region of the brush body 5 and improving powder adhesion efficiency. While the powder outlet column 311 also provides a certain positioning function for the brush body 5. Further ensuring alignment accuracy between the brush body 5 and the opening of the powder guiding channel 4 and preventing powder spillage.

[0065] In one embodiment, the brush body 5 envelops the upper end and a peripheral side of the powder outlet column 311.

[0066] In the above structure, the brush body 5 envelops the upper end and a peripheral side of the powder outlet column 311, allowing powder discharged from the powder outlet column 311 to make omnidirectional contact with the brush body 5, ensuring uniform adhesion of powder across various regions of the brush body 5 and avoiding localized powder deficiency or excessive accumulation on the brush body 5, thereby improving uniformity of makeup application. At the same time, the enveloping structure provides a certain sealing and protective effect on the upper-end opening of the powder outlet column 311, reducing entry of external dust into the powder guiding channel 4 and powder storage container 2 in a non-use state, and also reducing powder leakage from the opening.

[0067] In one embodiment, a diameter of the connecting portion 322 is larger than a diameter of the powder outlet column 311, the diameter of the powder outlet column 311 is smaller than a diameter of the powder feeding channel 42, and an upper end of the powder storage container 2 is detachably connected to the connecting portion 322.

[0068] By appropriately configuring the diameter relationship among the connecting portion 322, the powder outlet column 311, and the powder feeding channel 42. The diameter of the connecting portion 322 is greater than the diameter of the powder outlet column 311. This arrangement enhances the stability of the connection between the connecting portion 322 and the powder storage container 2, improves the sealing performance at the connection interface, and effectively prevents powder from leaking through any connecting gaps.

[0069] Furthermore, the diameter of the powder outlet column 311 is smaller than the diameter of the powder feeding channel 42, thereby enabling a “flow-restricted delivery” of the powder. This configuration ensures stable discharge of the powder while allowing precise control over the powder output amount, thus preventing excessive powder discharge and consequent waste.

[0070] Additionally, the detachable connection between the powder storage container 2 and the connecting portion 322 facilitates replenishment of powder and cleaning of the powder storage container 2, thereby significantly improving the ease of use and maintenance convenience of the product.

[0071] In one embodiment, an inner thread 3221 is provided on the inner sidewall of the connecting portion 322, and an outer thread 21 matching the inner thread 3221 is provided on the outer surface of the upper end of the powder storage container 2.

[0072] The provision of the inner thread 3221 on the inner sidewall of the connecting portion 322 and the outer thread 21 on the outer surface of the upper end of the powder storage container 2 enables detachable yet secure fixation of the powder storage container 2 to the connecting portion 322 by means of threaded engagement. The threaded connection exhibits excellent sealing performance, effectively preventing powder leakage from the connecting interface, while simultaneously ensuring firm fixation of the powder storage container 2 so as to avoid detachment or loosening during use.

[0073] Moreover, the threaded connection is simple and convenient to operate, allowing the user to quickly detach and reattach the powder storage container 2 for powder replenishment or cleaning and maintenance operations. The structure is simple and possesses strong practical utility.

[0074] In one embodiment, an annular gap is formed between the inner wall of the outer shell 1 and the outer wall of the mounting base 31. A protective sleeve 6 is disposed around the mounting base 31 in a vertically movable manner and is positioned within the annular gap.

[0075] In the above structure, the annular gap formed between the inner wall of the outer shell 1 and the outer wall of the mounting base 31 provides a stable and reliable movable mounting space for the protective sleeve 6, enabling smooth vertical sliding movement of the protective sleeve 6 along the mounting base 31. By being disposed around the exterior of the mounting base 31 and located within the annular gap, the protective sleeve 6 provides effective protection to the mounting base 31, the powder guiding channel 4, and the lower portion of the brush body 5, thereby reducing contamination by external dust and impurities, preventing damage to the powder guiding assembly 3 caused by external impact or collision, and ultimately extending the service life of the product. Furthermore, the design of the annular gap optimizes the internal spatial layout of the product, resulting in a more compact overall structure without compromising the portability of the cosmetic brush.

[0076] In one embodiment, the protective sleeve 6 has a first installation position and a second installation position. In the first installation position, the upper end of the protective sleeve 6 is lower than or flush with the top end of the brush body 5, thereby exposing the brush body 5. In the second installation position, the protective sleeve 6 moves upward such that its upper end protrudes beyond the outer shell 1 and covers the outer periphery of the brush body 5.

[0077] In the above structure, the protective sleeve 6 is configured with a first installation position and a second installation position, thereby enabling switching between different functional states to adapt to various usage scenarios. When in the first installation position, the brush body 5 remains exposed, allowing normal makeup application without adversely affecting the tactile feel or makeup application performance of the brush body 5. When in the second installation position, the protective sleeve 6 moves upward and covers the outer periphery of the brush body 5, thereby effectively protecting the bristles of the brush body 5 from compression deformation and abrasion, preventing residual powder on the bristles from falling off and contaminating clothing or other items, and further reducing contamination of the bristles by external dust. This arrangement significantly prolongs the service life of the brush body 5 and enhances the overall practicality of the product.

[0078] In one embodiment, an upper-end opening of the protective sleeve 6 extends outwardly to form an outer flange 61. When the protective sleeve 6 is in the second installation position, the flange 61 rests against the upper end surface or the outer side of the outer shell 1.

[0079] The provision of the outwardly extending flange 61 at the upper opening of the protective sleeve 6 enables the flange 61 to abut against the upper end surface or the outer side of the outer shell 1 when the protective sleeve 6 reaches the second installation position.

[0080] This configuration provides reliable position-limiting and fixing for the protective sleeve 6, preventing unintended downward movement of the protective sleeve 6 while in the second installation position, thereby ensuring stable coverage of the brush body 5 and maintaining the intended protective effect. At the same time, the flange 61 facilitates manual operation by the user to slide the protective sleeve 6, enabling rapid switching between the first installation position and the second installation position and improving operational convenience. Moreover, the flange 61 increases the structural strength of the upper end of the protective sleeve 6, reducing the risk of deformation at the opening of the protective sleeve 6.

[0081] In one embodiment, a limiting protrusion 62 is provided on the inner side of the lower end of the protective sleeve 6, and a platform 312 is formed on the outer side of the mounting base 31. When the protective sleeve 6 moves downward to the lower limit of its travel, the limiting protrusion 62 abuts against the platform 312.

[0082] The limiting protrusion 62 on the inner side of the lower end of the protective sleeve 6 cooperates with the platform 312 on the outer side of the mounting base 31. When the protective sleeve 6 reaches the lower limit of its downward travel, the limiting protrusion 62 abuts against the platform 312, thereby accurately limiting the downward stroke of the protective sleeve 6. This arrangement prevents excessive downward movement of the protective sleeve 6 that might otherwise cause collision with the powder storage container 2, the locking component 32, or other components, thus avoiding damage to the parts. Meanwhile, the engagement between the limiting protrusion 62 and the platform 312 enables the protective sleeve 6 to stably remain in the first installation position, ensuring complete exposure of the brush body 5 without interfering with makeup application, and improving the stability and reliability of the product during use.

[0083] In one embodiment, the cosmetic brush further includes a sealing component 7. The sealing component 7 is movably disposed within the brush body 5, and the sealing component 7 is capable of being inserted into or removed from an upper opening of the powder guiding channel 4.

[0084] The provision of the movable sealing component 7 allows the sealing component 7 to be selectively inserted into or withdrawn from the upper opening of the powder guiding channel 4. In the non-use state, insertion of the sealing component 7 into the upper opening of the powder guiding channel 4 achieves sealing of the powder guiding channel 4, effectively preventing powder leakage from the powder storage container 2 and simultaneously blocking external dust and impurities from entering the powder storage container 2 through the corresponding powder guiding channel 4 and contaminating the powder. In the use state, withdrawal of the sealing component 7 from the opening of the powder guiding channel 4 does not impede normal powder feeding. The structure is simple and the operation is convenient, further enhancing the sealing performance and practicality of the product while reducing powder waste.

[0085] In one embodiment, the cosmetic brush further includes a sealing component 7. The sealing component 7 is movably disposed within the brush body 5. The sealing component 7 is configured as a rod, with its lower end capable of being inserted into the upper-end opening of the powder outlet column 311. The sealing component 7 is made of an elastic material.

[0086] In the above structure, the sealing component 7 is a sealing rod whose lower end can be inserted into the upper-end opening of the powder outlet column 311. Thereby matching the structure of the powder outlet column 311 and achieving improved sealing performance. This configuration enables more precise blockage of the powder guiding channel 4, effectively preventing powder leakage and ingress of impurities. Since the sealing component 7 is made of an elastic material, when inserted into the opening of the powder outlet column 311, it can closely conform to the inner wall of the powder outlet column 311 through its own elasticity. Further enhancing the sealing effect while avoiding rigid contact that might cause wear to the opening of the powder outlet column 311, thereby extending the service life of the component. Additionally, the elastic material of the sealing component 7 provides a softer and more user-friendly operation for insertion and withdrawal, and can accommodate minor dimensional variations in the opening of the powder outlet column 311, improving the overall adaptability and robustness of the product.

[0087] In one embodiment, the cosmetic brush further includes an upper cover 8, wherein the upper cover 8 is detachably mounted over the top end of the outer shell 1 and covers the exterior of the brush body 5.

[0088] In the above structure, a detachable upper cover 8 is additionally provided. The upper cover 8 is configured to cover the top end of the outer shell 1 and the exterior of the brush body 5. In a non-use state, the upper cover 8 provides comprehensive protection for the brush body 5, preventing deformation and abrasion of the bristles of the brush body 5 due to compression, avoiding spillage of residual powder remaining on the bristles, and isolating the brush body 5 from external dust and impurities, thereby ensuring cleanliness of the brush body 5. The detachable design of the upper cover 8 does not interfere with normal use of the brush body 5, and enables the upper cover 8 to cooperate with the outer shell 1 and the powder storage container 2, resulting in improved overall sealing performance of the product, further protecting the internal powder and components, and enhancing the cleanliness and service life of the cosmetic brush.

[0089] In one embodiment, the upper cover 8 is fixed to the outer shell 1 by means of an interference fit, a threaded connection, or a snap-fit connection.

[0090] In the above structure, the upper cover 8 is secured to the outer shell 1 by means of an interference fit, threaded connection, snap-fit connection, or similar arrangements. Thereby accommodating different production requirements and product configurations.
