Description

Technical Field

[0001] This application belongs to the field of cosmetic tool technology, and in particular relates to a retractable makeup brush. Background Technology

[0002] The structure of existing makeup brushes is generally quite simple, usually consisting of three parts: the bristles, the bristle fixing part, and the brush handle, which are connected in sequence as an integrated form. However, existing makeup brushes are limited by the design of the handle, which is not only too long but also lacks folding or telescopic functions. This directly results in the overall size of the makeup brush being too large, making it easy to be restricted by space when carrying and storing, and its convenience needs to be improved. Utility Model Content

[0003] The purpose of this application is to address the aforementioned technical problems by providing a telescopic makeup brush. This brush features a sliding, adjustable telescopic rod that works in conjunction with the handle, allowing for flexible adjustment of the overall length. When retracted, the brush's overall size is significantly reduced, easily fitting various sizes of makeup bags and greatly improving portability and storage convenience. It also supports quick brush head replacement, and different types of brush heads can be installed simultaneously at both ends of the handle, meeting diverse makeup needs.

[0004] This application provides a retractable makeup brush, including a brush head, a brush handle, and further comprising: The grip is a cylindrical structure with openings at both the top and bottom ends. A limiting sleeve is provided with a limiting frame at its upper end and a limiting protrusion at its inner wall. The limiting sleeve is inserted into the grip bar, and the limiting frame abuts against the upper surface of the grip bar. A telescopic rod is slidably sleeved on a limiting sleeve, and a limiting groove is provided on the telescopic rod, with the limiting protrusion slidingly engaging with the limiting groove.

[0005] This telescopic makeup brush includes a brush head and handle, along with several key components such as a grip, a limiting sleeve, and a telescopic rod. The grip is a cylindrical structure with open top and bottom surfaces, facilitating the installation and assembly of other components. The limiting sleeve has a limiting frame at its upper end and multiple limiting protrusions on its inner wall. The limiting sleeve is inserted into the grip, and after installation, the limiting frame at the upper end of the limiting sleeve abuts against the upper surface of the grip, effectively limiting the position of the limiting sleeve and preventing excessive displacement during use. The telescopic rod is slidably fitted onto the limiting sleeve. A limiting groove is formed on the surface of the telescopic rod, matching the limiting protrusions on the inner wall of the limiting sleeve. When the telescopic rod slides within the limiting sleeve, the limiting protrusions slide into the limiting groove. This design guides the sliding direction of the telescopic rod, ensuring it slides stably along a pre-set trajectory. It also prevents the rod from rotating during sliding, guaranteeing the stability of the makeup brush during adjustment. By adjusting the sliding distance of the telescopic rod within the handle, the overall length of the makeup brush can be easily changed. When carrying the brush, the telescopic rod can be retracted to its shortest position, significantly reducing the overall size of the brush and making it easier to store in a makeup bag or other storage container, improving portability. Conversely, when using the brush for makeup application, the telescopic rod can be adjusted to a suitable length according to the user's hand habits and the needs of the application area, allowing for more comfortable and precise makeup application.

[0006] Furthermore, the grip bar is provided with mounting holes, and the limiting sleeve is provided with mounting blocks, the mounting blocks being made of elastic material.

[0007] To ensure a secure fit between the retaining sleeve and the handle, mounting holes are provided at specific locations on the handle. Correspondingly, a mounting block made of elastic material is provided on the outer wall of the retaining sleeve, matching the mounting hole. To install the retaining sleeve, simply align the mounting block on the retaining sleeve with the mounting hole on the handle, and then gently press the block. Due to its elasticity, the block deforms under pressure and smoothly enters the mounting hole. Once fully inserted, the block returns to its original shape, locking tightly into the hole, enabling quick installation of the retaining sleeve and handle. This installation method requires no additional tools, is simple and convenient, and effectively improves assembly efficiency. Furthermore, the tight and reliable engagement between the elastic mounting block and the mounting hole ensures that the retaining sleeve will not easily detach from the handle during long-term use, guaranteeing the stability of the retaining sleeve installation and thus ensuring the overall stability and lifespan of the makeup brush structure.

[0008] Furthermore, a friction block is installed at the lower end of the telescopic rod.

[0009] A friction block, made of a material with a certain degree of friction, is installed at the lower end of the telescopic rod. The outer diameter of the friction block matches the inner diameter of the handle, ensuring close contact between the friction block and the inner wall of the handle. When the telescopic rod slides within the handle, the friction block moves along with it. The friction between the friction block and the inner wall of the handle dampens the sliding motion. When the user stops applying force to the telescopic rod, the friction immediately stops it at its current position, preventing it from continuing to slide due to its own weight or other minor external forces. This design allows users to adjust the telescopic rod to any desired length without additional locking mechanisms, significantly improving the flexibility and convenience of using makeup brushes. Users can adjust the length of the telescopic rod and quickly fix it according to different stages and needs of makeup application, improving efficiency and effectiveness.

[0010] Furthermore, an installation cylinder is installed at the upper end of the telescopic rod. The upper end face of the installation cylinder is open, and an internal thread is provided at the opening of the upper end face of the installation cylinder. An external thread is provided on the brush handle, and the brush handle is installed on the installation cylinder through threaded engagement.

[0011] To enable replaceable brush heads, a mounting cylinder is installed at the upper end of the telescopic rod. The upper surface of the mounting cylinder is open, and an internal thread is provided at the opening. Correspondingly, an external thread is machined on the outer wall of the brush handle to match the internal thread of the mounting cylinder. To install the brush handle, simply align the threaded end of the brush handle with the opening of the mounting cylinder, and then rotate the brush handle clockwise. The engagement of the threads securely mounts the brush handle to the mounting cylinder. When replacing the brush head, simply rotate the brush handle counterclockwise to detach it from the mounting cylinder, and then replace it with a brush handle containing a brush head of a different size. This threaded connection method is not only simple in structure and quick and easy to install and disassemble, but also provides a secure and reliable connection, ensuring that the brush head will not loosen or fall off during use. By changing the brush heads to different sizes, users can flexibly choose the appropriate brush head according to the different makeup areas, such as eyes, face, lips, etc., and the desired makeup effect. This significantly improves the versatility and practicality of makeup brushes and meets the diverse makeup needs of users.

[0012] Furthermore, an installation sleeve is installed at the opening on the lower end face of the grip, and the installation sleeve is provided with an internal thread, which can be engaged with the external thread on the brush handle.

[0013] A mounting sleeve with internal threads is installed at the lower end of the handle, allowing for a threaded engagement with the external threads on the brush handle. This design allows users to install brush heads not only on the mounting sleeve at the upper end of the telescopic rod but also on the mounting sleeve at the lower end of the handle. Users can attach different sizes or types of brush heads to either end of the makeup brush according to their makeup needs; for example, a large brush head for applying makeup to one area and a smaller brush head for detail work on the other. Switching between brush heads is seamless; simply flip the brush over to quickly switch to the desired head, significantly saving time and improving makeup efficiency. This also avoids potential damage from frequent brush head removal and installation, further enhancing the convenience and practicality of the makeup brush.

[0014] Furthermore, the grip bar is provided with anti-slip texture.

[0015] By incorporating anti-slip textures on the outer surface of the handle, these textures, with their specific pattern design, effectively increase the friction of the handle. When a user holds the makeup brush for makeup application, the anti-slip textures increase the friction between the hand and the handle. Even when hands are sweaty or slippery due to the application of skincare or makeup products, this ensures a stable grip and prevents the makeup brush from slipping or falling out of the hand. This design not only improves the safety of using the makeup brush, preventing unnecessary damage or injury caused by the brush slipping out of the hand, but also allows the user to control the brush more steadily, improving the precision of makeup application and ensuring a more ideal makeup effect, thus providing a better user experience.

[0016] The beneficial effects of this application are: 1. The overall size of the makeup brush can be changed by adjusting the length of the telescopic rod. When retracted, it is small and easy to carry. When in use, it can be adjusted to a comfortable length according to hand habits and makeup application areas. 2. Supports brush head replacement, can adapt to different sizes of brush heads to meet diverse makeup needs; at the same time, the mounting sleeve at the lower end of the handle can be used to install additional brush heads, and you can quickly switch between the two ends by simply flipping it over. 3. When the telescopic pole slides, the limiting protrusion and the limiting groove work together to prevent rotation, and the friction block allows the telescopic pole to stay stably in any position; the anti-slip texture of the grip increases friction, so that even if your hands are smooth, you can hold it firmly and avoid slipping and dropping your hand, ensuring stable and safe use.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0021] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this application embodiment provides a telescopic makeup brush, including a brush head 100, a brush handle 200, and further comprising: The grip 300 is a cylindrical structure with openings on both the upper and lower ends. A limiting sleeve 500 is provided with a limiting frame 510 at its upper end and a limiting protrusion 520 at its inner wall. The limiting sleeve 500 is inserted into the grip bar 300, and the limiting frame 510 abuts against the upper surface of the grip bar 300. Telescopic rod 600, which is slidably sleeved on limiting sleeve 500, has a limiting groove 610 provided on it, and the limiting protrusion 520 is slidably engaged with the limiting groove 610.

[0022] This telescopic makeup brush includes a brush head 100 and a brush handle 200, and is also equipped with several important components such as a handle 300, a limiting sleeve 500, and a telescopic rod 600. The handle 300 has a cylindrical structure with open ends, facilitating the installation and assembly of other components. The limiting sleeve 500 has a limiting frame 510 at its upper end, and multiple limiting protrusions 520 are installed on its inner wall. The limiting sleeve 500 is installed on the handle 300 via a plug-in connection. After installation, the limiting frame 510 at the upper end of the limiting sleeve 500 abuts against the upper surface of the handle 300, effectively limiting the position of the limiting sleeve 500 on the handle 300 and preventing excessive displacement during use. The telescopic rod 600 is slidably mounted on the limiting sleeve 500. A limiting groove 610 is formed on the surface of the telescopic rod 600, matching the limiting protrusion 520 on the inner wall of the limiting sleeve 500. When the telescopic rod 600 slides within the limiting sleeve 500, the limiting protrusion 520 slides into the limiting groove 610. This engagement guides the sliding direction of the telescopic rod 600, ensuring it slides stably along a predetermined trajectory. It also prevents the telescopic rod 600 from rotating during sliding, thus ensuring the stability of the makeup brush during telescopic adjustment. By adjusting the sliding distance of the telescopic rod 600 within the handle 300, the overall length of the makeup brush can be easily changed. When carrying the makeup brush, the telescopic rod 600 can be retracted to its shortest state, greatly reducing the overall size of the makeup brush and making it easier to put into a makeup bag or other storage container, thus improving portability. When using the makeup brush for makeup operations, the telescopic rod 600 can be adjusted to a suitable length according to the user's hand habits and the needs of the makeup area, allowing the user to perform makeup operations more comfortably and accurately.

[0023] Example 2: like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this application embodiment provides a telescopic makeup brush, which, in addition to the above-mentioned technical features, has a mounting hole 310 on the handle 300 and a mounting block 320 on the limiting sleeve 500, the mounting block 320 being made of elastic material.

[0024] To ensure a secure installation of the retaining sleeve 500 on the grip 300, a mounting hole 310 is provided at a specific location on the grip 300. Correspondingly, a mounting block 320, made of an elastic material, is provided on the outer wall of the retaining sleeve 500 to match the mounting hole 310. When installing the retaining sleeve 500, simply align the mounting block 320 on the retaining sleeve 500 with the mounting hole 310 on the grip 300, and then gently press the mounting block 320. Due to its elasticity, the mounting block 320 deforms under pressure and smoothly enters the mounting hole 310. Once fully inserted into the mounting hole 310, the mounting block 320 returns to its original shape, thus tightly engaging with the mounting hole 310, achieving quick installation between the retaining sleeve 500 and the grip 300. This installation method requires no additional tools, is simple and convenient to operate, and effectively improves assembly efficiency. Meanwhile, the snap-fit ​​connection between the elastic mounting block 320 and the mounting hole 310 is tight and reliable, ensuring that the limiting sleeve 500 will not easily fall off the handle 300 during long-term use, thus ensuring the stability of the limiting sleeve 500 installation and thereby ensuring the stability and service life of the overall structure of the makeup brush.

[0025] Example 3: like Figure 2 , Figure 4 As shown, this application embodiment provides a telescopic makeup brush, which, in addition to the above-mentioned technical features, has a friction block 620 installed at the lower end of the telescopic rod 600.

[0026] A friction block 620 is installed at the lower end of the telescopic rod 600. This friction block 620 is made of a material with a certain degree of friction, and its outer diameter matches the inner diameter of the grip 300, allowing it to make close contact with the inner wall of the grip 300. When the telescopic rod 600 slides within the grip 300, the friction block 620 moves along with it. The friction between the friction block 620 and the inner wall of the grip 300 provides damping for the sliding of the telescopic rod 600. When the user stops applying external force to the telescopic rod 600, the friction immediately stops it at its current position, preventing it from continuing to slide due to its own weight or other minor external forces. This design allows users to adjust the telescopic rod 600 to any desired length according to their actual needs, and then keep the telescopic rod 600 stably in that position without the need for an additional locking device. This significantly improves the flexibility and convenience of using makeup brushes. Users can adjust the length of the telescopic rod 600 at any time and quickly fix it according to different stages and needs of makeup operation, thereby improving makeup efficiency and effect.

[0027] Example 4: like Figure 1 , Figure 2 , Figure 3 As shown, this application embodiment provides a telescopic makeup brush. In addition to the above-mentioned technical features, the telescopic rod 600 has an installation cylinder 630 installed at its upper end. The upper end face of the installation cylinder 630 is open, and the opening of the upper end face of the installation cylinder 630 is provided with an internal thread. The brush handle 200 is provided with an external thread, and the brush handle 200 is installed on the installation cylinder 630 through threaded engagement.

[0028] To enable the replaceable brush head 100, an mounting cylinder 630 is installed at the upper end of the telescopic rod 600. The upper end face of the mounting cylinder 630 is open, and an internal thread is provided at the opening. Correspondingly, an external thread matching the internal thread of the mounting cylinder 630 is machined on the outer wall of the brush handle 200. When installing the brush handle 200, simply align the threaded end of the brush handle 200 with the opening of the mounting cylinder 630, and then rotate the brush handle 200 clockwise. The engagement of the threads securely mounts the brush handle 200 onto the mounting cylinder 630. When replacing the brush head 100, simply rotate the brush handle 200 counterclockwise to remove it from the mounting cylinder 630, and then replace it with a brush handle 200 fitted with a brush head 100 of a different size. This threaded connection method is not only simple in structure and easy to install and disassemble, but also provides a stable and reliable connection, ensuring that the brush head 100 will not loosen or fall off during use. By changing the brush head 100 to different sizes, users can flexibly choose the appropriate brush head 100 according to different makeup areas, such as eyes, face, lips, etc., and the desired makeup effect, significantly improving the versatility and practicality of the makeup brush and meeting the diverse makeup needs of users.

[0029] Example 5: like Figure 2 , Figure 3 As shown, this application embodiment provides a telescopic makeup brush, which, in addition to the above-mentioned technical features, has an installation sleeve 530 installed at the opening on the lower end face of the handle 300. The installation sleeve 530 is provided with an internal thread, which can be engaged with the external thread on the brush handle 200.

[0030] A mounting sleeve 530 is installed at the opening on the lower end face of the handle 300. The inner wall of the mounting sleeve 530 has internal threads, which engage with the external threads on the brush handle 200. This design allows the user to install not only the brush head 100 on the mounting sleeve 630 at the upper end of the telescopic rod 600, but also a brush handle 200 with a brush head 100 on the mounting sleeve 530 at the lower end of the handle 300. During use, the user can install different sizes or types of brush heads 100 at each end of the makeup brush according to their makeup needs. For example, one end can be fitted with a large brush head 100 for applying makeup to large areas, while the other end can be fitted with a small brush head 100 for detail application. When it is necessary to switch to different brush heads 100, there is no need to disassemble or replace them. Simply flip the makeup brush over to quickly switch to the desired brush head 100. This significantly saves time when changing brush heads 100, improves makeup efficiency, and avoids the problem of component damage that may be caused by frequent disassembly and installation of brush heads 100. This further enhances the convenience and practicality of using makeup brushes.

[0031] Example 6: like Figure 1 , Figure 2 As shown in the figure, this application embodiment provides a telescopic makeup brush, which, in addition to the above-mentioned technical features, has anti-slip texture 550 on the handle 300.

[0032] By processing anti-slip textures 550 on the outer surface of the handle 300, these textures 550, with a specific pattern design, effectively increase the friction of the outer surface of the handle 300. When the user holds the makeup brush for makeup application, the anti-slip textures 550 increase the friction between the hand and the handle 300. Even when the hands are sweaty or slippery due to the application of skincare or makeup products, it ensures that the user can firmly grip the handle 300, preventing the makeup brush from slipping or falling out of the hand during use. This design not only improves the safety of using the makeup brush, preventing unnecessary damage or injury to the user due to the makeup brush slipping out of the hand, but also allows the user to control the makeup brush more stably, improving the precision of makeup application, ensuring a more ideal makeup effect, and providing the user with a better user experience.
