[0001] This application relates to the field of cosmetic packaging technology, and more particularly to a powder box. Background Technology
[0002] In related technologies, the brush assembly that comes with the powder cartridge is usually fixed inside the powder cartridge, making it inconvenient to access the brush assembly. Utility Model Content
[0003] In view of this, embodiments of this application aim to provide a powder box to improve the inconvenience of using powder brush components.
[0004] To achieve the above objectives, embodiments of this application provide a powder cartridge, which includes: A box base and a box lid, wherein the box lid is rotatably connected to the box base; A paint brush assembly is rotatably connected to the box base, the paint brush assembly has a first limiting part, and the box cover has a second limiting part; The lid has a closed position, a first open position, and a second open position. The lid is in the closed position, and the first limiting part and the second limiting part are spaced apart. The lid rotates relative to the box base and the paint assembly, causing the second limiting part to move closer to the first limiting part until the second limiting part abuts against the first limiting part, thereby switching the lid from the closed position to the first open position. The lid, through the second limiting part, drives the paint assembly to rotate together relative to the box base, thereby switching the lid from the first open position to the second open position.
[0005] In some embodiments, the lid is formed with a third limiting portion, and in the second open position, the first limiting portion abuts against the second limiting portion, and the first limiting portion and the third limiting portion are spaced apart; The lid rotates relative to the box base and the paint assembly to separate the first limiting part from the second limiting part, and the third limiting part moves closer to the first limiting part until the third limiting part abuts against the first limiting part, so that the lid switches from the second open position to the first open position. The lid, through the third limiting part, causes the paint assembly to rotate relative to the box base, so that the lid switches from the first open position to the closed position.
[0006] In some embodiments, the first limiting part has a first limiting surface and a second limiting surface formed at both ends along the rotation direction of the box cover, the second limiting part has a third limiting surface, and the third limiting part has a fourth limiting surface; During the process of switching the lid from the first open position to the second open position, the first limiting surface and the third limiting surface abut against each other; during the process of switching the lid from the first open position to the closed position, the second limiting surface abuts against the fourth limiting surface.
[0007] In some embodiments, with the rotation center of the lid as the vertex, the central angle between the first limiting surface and the second limiting surface is smaller than the central angle between the third limiting surface and the fourth limiting surface. The first limiting part is inserted between the third limiting surface and the fourth limiting surface and can rotate between the third limiting surface and the fourth limiting surface along the rotation direction of the lid.
[0008] In some embodiments, when switching from the closed position to the first open position, the rotation angle of the lid about the rotation center of the lid is between 30° and 150°.
[0009] In some embodiments, when switching from the first open position to the second open position, the rotation angle of the paint assembly about the rotation center of the lid is between 30° and 150°.
[0010] In some embodiments, with the rotation center of the lid as the vertex, the central angle between the third limiting surface and the fourth limiting surface is between 90° and 270°.
[0011] In some embodiments, with the rotation center of the lid as the vertex, the central angles corresponding to the first limiting surface and the second limiting surface are between 45° and 180°.
[0012] In some embodiments, the powder box further includes a rotating shaft, and the box cover, the brush assembly, and the box base are respectively formed with a first rotating hole, a second rotating hole, and a third rotating hole. The rotating shaft passes through the first rotating hole, the second rotating hole, and the third rotating hole, so that the box base is rotatably connected to the box cover and the brush assembly, respectively.
[0013] In some embodiments, the lid has a first rotating portion with a first rotating hole formed along a first direction; the brush assembly has a second rotating portion with a second rotating hole formed along the first direction; the base has a third rotating portion with a third rotating hole formed along the first direction; and the first rotating portion, the second rotating portion, and the third rotating portion at least partially overlap in the first direction to align the first rotating hole, the second rotating hole, and the third rotating hole.
[0014] In some embodiments, the first limiting portion is formed on the end face of the second rotating portion along the first direction, and the second limiting portion and the third limiting portion are formed on the end face of the first rotating portion along the first direction, and the second limiting portion and the third limiting portion are integrally formed.
[0015] In some embodiments, the painting assembly includes a brush and a brush holder, the brush holder being rotatably connected to the box base, and the brush engaging with the brush holder.
[0016] The powder cartridge provided in this application embodiment has a first limiting part on the brush assembly and a second limiting part on the lid. When the lid is in the closed position, the first and second limiting parts are spaced apart. The lid rotates relative to the base and brush assembly, causing the second limiting part to move closer to the first limiting part until the second limiting part abuts against the first limiting part, thus switching the lid from the closed position to the first open position. The lid, through the second limiting part, drives the brush assembly to rotate relative to the base, thus switching the lid from the first open position to the second open position. In this way, after the user opens the lid to a certain angle, the lid can drive the brush assembly to rotate together. When the lid is in the second open position, the brush assembly is spaced a certain distance from both the base and the lid, which facilitates the user in taking the brush assembly out of the powder cartridge, improving the convenience of taking out the brush assembly and the user experience of the powder cartridge.

[0024] In related technologies, the brush assembly that comes with the powder cartridge is usually fixed inside the powder cartridge, making it inconvenient to access the brush assembly.
[0025] Based on the above, this application provides a powder box 10. Please refer to [link / reference]. Figures 1 to 10 The powder box 10 includes a base 11, a lid 12, and a brush assembly 13. The lid 12 is rotatably connected to the base 11. The brush assembly 13 is rotatably connected to the base 11. The brush assembly 13 has a first limiting portion 132a. The lid 12 has a second limiting portion 12b. The lid 12 has a closed position, a first open position, and a second open position. In the closed position, the first limiting portion 132a and the second limiting portion 12b are spaced apart. The lid 12 rotates relative to the base 11 and the brush assembly 13, causing the second limiting portion 12b to move closer to the first limiting portion 132a until the second limiting portion 12b abuts against the first limiting portion 132a, thereby switching the lid 12 from the closed position to the first open position. The lid 12, through the second limiting portion 12b, drives the brush assembly 13 to rotate together relative to the base 11, thereby switching the lid 12 from the first open position to the second open position.
[0026] The lid 12 is rotatably connected to the base 11, and the paint assembly 13 is rotatably connected to the base 11. That is, the base 11 is rotatably connected to both the lid 12 and the paint assembly 13, so that the paint assembly 13 and the lid 12 are indirectly rotatably connected, and the paint assembly 13 and the lid 12 can rotate relative to each other.
[0027] The lid 12 has a closed position, a first open position, and a second open position. The closed position is the position of the lid 12 when the powder box 10 is completely closed. The second open position is the position where the lid 12 is opened to its maximum extent.
[0028] Here, the rotation angle from the closed position to the first open position is smaller than the rotation angle from the closed position to the second open position. That is, the second open position is further away from the closed position than the first open position, and the opening angle is larger.
[0029] The lid 12 rotates relative to the base 11 and the paint assembly 13, causing the second limiting part 12b to move closer to the first limiting part 132a until the second limiting part 12b abuts against the first limiting part 132a, thus switching the lid 12 from the closed position to the first open position. In other words, in the first open position, the second limiting part 12b abuts against the first limiting part 132a. Meanwhile, in the closed position, because the first limiting part 132a and the second limiting part 12b are spaced apart, there is no mutual restraint between the lid 12 and the paint assembly 13. Therefore, when the user opens the lid 12 from the closed position, the paint assembly 13 will not rotate along with it; instead, the lid 12 rotates independently. During the process of rotating from the closed position to the first open position of the lid 12, the second limiting part 12b on the lid 12 gradually approaches the first limiting part 132a on the paint assembly 13 until the second limiting part 12b abuts against the first limiting part 132a. At this time, a one-way limiting is formed between the lid 12 and the paint assembly 13 in the rotation direction of opening the lid 12, so that the lid 12 switches to the first open position.
[0030] When the lid 12 is in the first open position, the user continues to open the lid 12. Since the second limiting part 12b abuts against the first limiting part 132a, the lid 12 can drive the paint assembly 13 to rotate relative to the box base 11 and continue to open, so that the lid 12 switches from the first open position to the second open position.
[0031] It is understandable that the rotation center of the lid 12 and the rotation center of the paint assembly 13 may or may not coincide.
[0032] The powder box 10 provided in this embodiment of the application has a first limiting part 132a on the powder brush assembly 13 and a second limiting part 12b on the lid 12. When the lid 12 is in the closed position, the first limiting part 132a and the second limiting part 12b are spaced apart. The lid 12 rotates relative to the box base 11 and the powder brush assembly 13, causing the second limiting part 12b to move closer to the first limiting part 132a until the second limiting part 12b abuts against the first limiting part 132a, thereby switching the lid 12 from the closed position to the first open position. 2. The second limiting part 12b drives the brush assembly 13 to rotate relative to the box base 11, so that the box cover 12 switches from the first open position to the second open position. In this way, after the user opens the box cover 12 to a certain angle, the box cover 12 can drive the brush assembly 13 to rotate together. When the box cover 12 is in the second open position, the brush assembly 13 is separated from the box base 11 and the box cover 12 by a certain distance, which is conducive to the user taking out and putting out the brush assembly 13 from the powder box 10, improving the convenience of taking out and putting out the brush assembly 13 and the user experience of the powder box 10.
[0033] For example, during the closing of the lid 12, the lid 12 may directly contact the paint assembly 13, causing the lid 12 to retract along with the paint assembly 13. Alternatively, the limiting structure on the lid 12 may contact and limit the limiting structure on the paint assembly 13, thereby causing the paint assembly 13 and the lid 12 to retract together. No limitation is made here.
[0034] In some embodiments, please refer to Figures 1 to 10 The lid 12 has a third limiting portion 12c. In the second open position, the first limiting portion 132a abuts against the second limiting portion 12b, and the first limiting portion 132a and the third limiting portion 12c are spaced apart. The lid 12 rotates relative to the box base 11 and the paint assembly 13, causing the first limiting portion 132a to separate from the second limiting portion 12b, and the third limiting portion 12c to move closer to the first limiting portion 132a until the third limiting portion 12c abuts against the first limiting portion 132a, thereby switching the lid 12 from the second open position to the first open position. The lid 12, through the third limiting portion 12c, drives the paint assembly 13 to rotate relative to the box base 11, thereby switching the lid 12 from the first open position to the closed position.
[0035] In the second open position, the first limiting part 132a on the paint assembly 13 abuts against the second limiting part 12b of the lid 12, and the first limiting part 132a on the paint assembly 13 is spaced apart from the third limiting part 12c of the lid 12. At the same time, when the user closes the lid 12 from the second open position, the lid 12 rotates relative to the base 11 and the paint assembly 13, so that the first limiting part 132a separates from the second limiting part 12b, and the third limiting part 12c moves closer to the first limiting part 132a. That is, the first limiting part 132a is located between the second limiting part 12b and the third limiting part 12c of the lid 12. In this way, the third limiting part 12c moves closer to the first limiting part 132a as the second limiting part 12b moves away from the first limiting part 132a.
[0036] It is understandable that, since the first limiting part 132a and the second limiting part 12b are in a one-way limiting contact when the lid 12 is in the second open position, when the lid 12 is closed from the second open position, the lid 12 will rotate independently relative to the base 11 and the paint assembly 13, the second limiting part 12b of the lid 12 will separate from the first limiting part 132a of the paint assembly 13, and at the same time, the third limiting part 12c will move closer to the first limiting part 132a.
[0037] It should be noted that the state of the powder box 10 differs when the lid 12 is switched from the second open position to the first open position compared to when it is switched from the closed position to the first open position. Although the lid 12 is always in the first open position, the position of the powder brush assembly 13 is different. When the lid 12 is switched from the second open position to the first open position, the powder brush assembly 13 is in its fully open position; when the lid 12 is switched from the closed position to the first open position, the powder brush assembly 13 is in its stored position.
[0038] During the process of gradually switching the lid 12 from the closed position to the first open position and the second open position, the lid 12 first rotates independently. After the lid 12 rotates to the maximum angle between itself and the brush assembly 13, the lid 12 drives the brush assembly 13 to rotate together until the lid 12 is opened to the maximum. In this way, the brush assembly 13, the lid 12 and the base 11 will all be at a certain angle, which can increase the user's operating space and facilitate the user's makeup-related operations.
[0039] During the process of the lid 12 gradually switching from the second open position to the first open position and then to the closed position, the lid 12 first rotates independently. After the lid 12 rotates to the minimum angle between itself and the brush assembly 13, the lid 12 drives the brush assembly 13 to rotate together until the lid 12 is closed to the closed position. In this way, the chance of direct contact between the lid 12 and the brush head of the brush assembly 13 can be reduced, thereby improving the cleanliness of the lid 12.
[0040] In this embodiment, by providing a third limiting part 12c on the lid 12, during the process of closing the lid 12 from the second open position, after closing to a certain angle, the lid 12 can drive the brush assembly 13 to retract together through the limiting between the third limiting part 12c and the first limiting part 132a. This can improve the situation where the lid 12 and the brush head of the brush assembly 13 are in direct contact, reduce the probability of mutual contamination between the lid 12 and the brush assembly 13, and improve the cleanliness of the lid 12.
[0041] In some embodiments, please refer to Figures 1 to 10 The first limiting part 132a has a first limiting surface 132d and a second limiting surface 132e formed at both ends along the rotation direction of the lid 12. The second limiting part 12b has a third limiting surface 12d. The third limiting part 12c has a fourth limiting surface 12e. During the process of switching the lid 12 from the first open position to the second open position, the first limiting surface 132d and the third limiting surface 12d abut. During the process of switching the lid 12 from the first open position to the closed position, the second limiting surface 132e abuts against the fourth limiting surface 12e.
[0042] During the process of switching the lid 12 from the first open position to the second open position, the first limiting surface 132d of the first limiting part 132a and the third limiting surface 12d of the second limiting part 12b abut against each other, so that the lid 12 can drive the paint assembly 13 to rotate together.
[0043] Understandably, when the lid 12 is in the closed position, the first limiting surface 132d and the third limiting surface 12d are spaced apart, and the second limiting surface 132e abuts against the fourth limiting surface 12e. During the process of switching the lid 12 from the closed position to the first open position, the third limiting surface 12d moves closer to the first limiting surface 132d, while simultaneously, the second limiting surface 132e separates from the fourth limiting surface 12e and gradually moves away from it. In the first open position, the first limiting surface 132d and the third limiting surface 12d abut against each other, while the second limiting surface 132e and the fourth limiting surface 12e are separated to their maximum extent. In the second open position, the first limiting surface 132d and the third limiting surface 12d remain abut against each other.
[0044] During the closing process of the lid 12, specifically, as the lid 12 switches from the second open position to the first open position, the first limiting surface 132d and the third limiting surface 12d separate and gradually move away from each other, while the second limiting surface 132e and the fourth limiting surface 12e gradually move closer together. In the first open position, the second limiting surface 132e and the fourth limiting surface 12e are in contact, and the first limiting surface 132d and the third limiting surface 12d are separated to their maximum extent. During the switching process from the first open position to the closed position, the second limiting surface 132e and the fourth limiting surface 12e remain in contact.
[0045] In this embodiment, the first limiting part 132a forms a limiting position by contacting the second limiting part 12b and the third limiting part 12c, which can improve the stress concentration, increase the force value transmitted by the limiting contact, and thus improve the reliability and stability of the box cover 12 driving the paint assembly 13 to rotate.
[0046] In some embodiments, please refer to Figures 1 to 10 With the rotation center of the lid 12 as the vertex, the central angle between the first limiting surface 132d and the second limiting surface 132e is smaller than the central angle between the third limiting surface 12d and the fourth limiting surface 12e. The first limiting part 132a is inserted between the third limiting surface 12d and the fourth limiting surface 12e, and can rotate between the third limiting surface 12d and the fourth limiting surface 12e in the rotation direction of the lid 12.
[0047] It should be noted that in this embodiment, the rotation center of the box cover 12 coincides with the rotation center of the paint assembly 13, that is, the center of the central angle corresponding to the first limiting surface 132d and the second limiting surface 132e coincides with the center of the central angle corresponding to the third limiting surface 12d and the fourth limiting surface 12e.
[0048] like Figure 6 and Figure 7 As shown, the rotation center of the box cover 12 is represented by D1, and the rotation center of the paint assembly 13 is represented by D2.
[0049] like Figure 4 As shown, the central angle between the first limiting surface 132d and the second limiting surface 132e is denoted by A1, and the central angle between the third limiting surface 12d and the fourth limiting surface 12e is denoted by A2. It can be understood that the difference between A2 and A1 is the angle at which the paint assembly 13 and the cover 12 can rotate relative to each other.
[0050] Here, by setting the central angle between the first limiting surface 132d and the second limiting surface 132e to be smaller than the central angle between the third limiting surface 12d and the fourth limiting surface 12e, the first limiting part 132a can be inserted between the third limiting surface 12d and the fourth limiting surface 12e, and can rotate between the third limiting surface 12d and the fourth limiting surface 12e along the rotation direction of the lid 12, so that after the lid 12 rotates a certain angle on its own, it drives the paint assembly 13 to rotate together.
[0051] In some embodiments, please refer to Figures 4 to 10 When switching from the closed position to the first open position, the rotation angle of the lid 12 around the rotation center of the lid 12 is between 30° and 150°.
[0052] It should be noted that the rotation angle of the lid 12 around its center of rotation when switching from the closed position to the first open position refers to the maximum opening angle when the lid 12 is opened to the first open position. This angle determines the maximum gap angle between the lid 12 and the paint assembly 13.
[0053] For example, when switching from the closed position to the first open position, the rotation angle of the lid 12 around the rotation center of the lid 12 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, or 150°, etc.
[0054] In this embodiment, by limiting the rotation angle of the lid 12 around its rotation center from the closed position to the first open position, the rotation angle of the lid 12 is between 30° and 150°. This ensures that during the opening process, whether in the first open position, the second open position, or between the first open position and the second open position, there is at least a 30° interval angle and at most a 150° interval angle between the lid 12 and the paint assembly 13. This ensures that the maximum interval angle between the lid 12 and the paint assembly 13 is within a reasonable range, making it convenient for the user to insert their fingers between the lid 12 and the paint assembly 13 and to pick up and put down the paint assembly 13.
[0055] In some embodiments, please refer to Figures 4 to 10 When switching from the first open position to the second open position, the rotation angle of the paint assembly 13 around the rotation center of the box cover 12 is between 30° and 150°.
[0056] It should be noted that when switching from the first open position to the second open position, the rotation angle of the brush component 13 around the rotation center of the lid 12 refers to the maximum angle at which the lid 12 can rotate synchronously with the brush component 13. The larger this angle is, the greater the gap angle between the brush component 13 and the base 11 will be, making it easier for the user to insert their fingers between the brush component 13 and the base 11 to perform makeup operations.
[0057] For example, when switching from the first open position to the second open position, the rotation angle of the paint assembly 13 around the rotation center of the box cover 12 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, or 150°, etc.
[0058] In this embodiment, by limiting the rotation angle of the brush assembly 13 around the rotation center of the lid 12 from the first open position to the second open position, the rotation angle is between 30° and 150°. This ensures that during the opening process, in the second open position, there is a gap angle of at least 30° and at most 150° between the lid 12 and the base 11, facilitating the user's fingers to be inserted between the brush assembly 13 and the base 11 for makeup application.
[0059] In one specific embodiment, please refer to Figure 1 , Figure 8 , Figure 9 When switching from the closed position to the first open position, the lid 12 rotates 90° around its center of rotation. When switching from the first open position to the second open position, the lid 12 rotates 90° around its center of rotation. In other words, when switching from the closed position to the second open position, the lid 12 rotates 180° around its center of rotation. When the lid 12 is opened to the second open position, the paint assembly 13 is opened to a 90° position.
[0060] In some embodiments, please refer to Figure 4 With the rotation center of the lid 12 as the vertex, the central angle between the third limiting surface 12d and the fourth limiting surface 12e is between 90° and 270°.
[0061] For example, the central angles corresponding to the third limiting surface 12d and the fourth limiting surface 12e can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, 180°, 185°, 190°, 195°, 200°, 205°, 210°, 215°, 220°, 225°, 230°, 235°, 240°, 245°, 250°, 255°, 260°, 265°, or 270°, etc.
[0062] Thus, by making the central angle between the third limiting surface 12d of the second limiting part 12b and the fourth limiting surface 12e of the third limiting part 12c between 90° and 270°, the second limiting part 12b and the third limiting part 12c can have a certain structural strength, which is beneficial to improving the reliability of the positioning between the paint assembly 13 and the box cover 12.
[0063] In some embodiments, please refer to Figure 4 With the rotation center of the lid 12 as the vertex, the central angles corresponding to the first limiting surface 132d and the second limiting surface 132e are limited to between 45° and 180°.
[0064] For example, the central angles corresponding to the first limiting surface 132d and the second limiting surface 132e can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, or 180°, etc.
[0065] Here, by limiting the central angle between the first limiting surface 132d and the second limiting surface 132e formed by the first limiting part 132a on the paint assembly 13 to between 45° and 180°, the first limiting part 132a has a certain structural strength, which is beneficial to improving the reliability of the limiting between the paint assembly 13 and the box cover 12.
[0066] In some embodiments, please refer to Figures 1 to 7 The powder box 10 also includes a rotating shaft 14. The lid 12, the brush assembly 13, and the base 11 are respectively provided with a first rotating hole 12f, a second rotating hole 132c, and a third rotating hole 11a. The rotating shaft 14 passes through the first rotating hole 12f, the second rotating hole 132c, and the third rotating hole 11a, so that the base 11 is rotatably connected to the lid 12 and the brush assembly 13, respectively.
[0067] The rotating shaft 14 passes through the first rotating hole 12f, the second rotating hole 132c and the third rotating hole 11a, that is, the first rotating hole 12f, the second rotating hole 132c and the third rotating hole 11a are coaxial.
[0068] This makes the structure simple and reliable, easy to assemble, and convenient to manufacture.
[0069] For example, there are two rotating shafts 14, and the cover 12, the paint assembly 13 and the base 11 respectively form two first rotating holes 12f, two second rotating holes 132c and two third rotating holes 11a.
[0070] In some embodiments, please refer to Figures 1 to 7 The lid 12 has a first rotating portion 12a. The first rotating portion 12a has a first rotating hole 12f formed along a first direction. The paint assembly 13 has a second rotating portion 132b. The second rotating portion 132b has a second rotating hole 132c formed along the first direction. The base 11 has a third rotating portion 11b. The third rotating portion 11b has a third rotating hole 11a formed along the first direction. The first rotating portion 12a, the second rotating portion 132b, and the third rotating portion 11b at least partially overlap in the first direction, so that the first rotating hole 12f, the second rotating hole 132c, and the third rotating hole 11a are aligned.
[0071] It should be noted that the first direction can be perpendicular to the rotation direction of the lid 12, and the first direction can be parallel to the rotation center axis of the lid 12.
[0072] For example, Figures 1 to 7 R1 in the equation can be the first direction.
[0073] In this embodiment, by at least partially overlapping the first rotating part 12a, the second rotating part 132b and the third rotating part 11b in the first direction, the first rotating hole 12f of the cover 12, the second rotating hole 132c of the paint brush assembly 13 and the third rotating hole 11a of the box base 11 are arranged and aligned in sequence along the first direction, so that the rotating shaft 14 can cooperate with the first rotating hole 12f, the second rotating hole 132c and the third rotating hole 11a respectively along the first direction.
[0074] For example, the first rotating part 12a is cylindrical, and the central axis of the first rotating hole 12f coincides with the central axis of the first rotating part 12a.
[0075] In some embodiments, please refer to Figures 1 to 7 A first limiting portion 132a is formed on the end face of the second rotating portion 132b along the first direction. A second limiting portion 12b and a third limiting portion 12c are formed on the end face of the first rotating portion 12a along the first direction, and the second limiting portion 12b and the third limiting portion 12c are formed as one piece.
[0076] The second limiting part 12b and the third limiting part 12c are formed as one unit, which can improve the structural strength of the second limiting part 12b and the third limiting part 12c.
[0077] By forming a second limiting part 12b and a third limiting part 12c on the end face of the first rotating part 12a along the first direction, and forming a first limiting part 132a on the end face of the second rotating part 132b along the first direction, the first limiting part 132a can be placed between the second limiting part 12b and the third limiting part 12c simply by docking the first rotating part 12a and the second rotating part 132b along the first direction, which is beneficial for assembly and improving the compactness of the structure.
[0078] In some embodiments, please refer to Figures 1 to 10 The paint assembly 13 includes a brush 131 and a paint holder 132. The paint holder 132 is rotatably connected to the box base 11. The brush 131 and the paint holder 132 are engaged in a snap-fit relationship.
[0079] The paint holder 132 has a second rotating part 132b, a first limiting part 132a is formed on the end face of the second rotating part 132b along the first direction, and a second rotating hole 132c is formed on the second rotating part 132b along the first direction.
[0080] In this embodiment, the brush assembly 13 is divided into a brush 131 and a brush holder 132, which are connected by a snap-fit mechanism, making the brush 131 detachable and more convenient for users.
[0081] For example, one of the brush 131 and the paint holder 132 has a slot 131a, and the other has a snap-fit protrusion 132f, and the slot 131a and the snap-fit protrusion 132f engage in a snap-fit relationship.
[0082] For example, the brush 131 and the brush holder 132 simultaneously form a socket engagement and a snap-fit engagement. This further enhances the fixation of the brush 131 and reduces the likelihood of the brush 131 wobbling inside the powder box 10.
[0083] For example, the brush 131 has a fixing groove 131b, and the paintbrush holder 132 extends into the fixing groove 131b and forms a sleeve between it and the brush 131. The groove wall of the fixing groove 131b has a protruding rib 131c, which is used to abut against the outer wall of the paintbrush holder 132 to improve the connection stability of the detachable connection between the brush 131 and the paintbrush holder 132.
[0084] In some embodiments, please refer to 2. Figure 4 , Figures 8 to 10 The powder box 10 also includes a mirror 15, which is located inside the lid 12.
[0085] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
