Description

Technical Field

[0001] This utility model relates to a telescopic makeup brush. Background Technology

[0002] Traditional makeup brushes have bristles on the handle, covered by a cap. Removing or attaching the cap can easily cause the bristles to split, and the cap is prone to being lost. To address this, some makeup brushes incorporate a cavity at one end of the handle, housing the bristles on the brush head. A spiral lifting mechanism connects the brush head to this cavity, and rotating the brush head relative to the handle moves the bristles up and down, thus both spreading the bristles and slightly increasing the brush's length. However, this design results in a shorter brush length during use, making it inconvenient for the user to hold. Conversely, significantly increasing the handle length would lead to an excessively large brush when not in use, hindering storage and portability. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a telescopic makeup brush that can extend to a longer size during use and shorten to a shorter size for easy storage and carrying.

[0004] A telescopic makeup brush according to an embodiment of the present invention includes: an outer tube, an inner tube telescopically attached to one end of the outer tube, and a first support telescopically attached to one end of the inner tube extending beyond the outer tube. The first support is used to mount brush bristles. A linkage mechanism is provided between the outer tube, the inner tube, and the first support. The linkage mechanism has an extended state and a retracted state. A limiting mechanism is provided between the outer tube and the inner tube, or between the inner tube and the first support, to stabilize the linkage mechanism in the extended state. When the linkage mechanism is in the extended state, the inner tube extends relative to the outer tube, and the first support extends relative to the inner tube. When the linkage mechanism is in the retracted state, the inner tube retracts relative to the outer tube, and the first support retracts relative to the inner tube.

[0005] A telescopic makeup brush according to an embodiment of the present invention has at least the following features:

[0006] Beneficial effects:

[0007] When using a makeup brush, extend the inner sleeve relative to the outer sleeve. Under the action of the linkage mechanism, the bristles on the first support also extend outward relative to the inner sleeve. The inner sleeve and the outer sleeve form the brush handle, which can be extended to a longer size for easy gripping and use. When storing the makeup brush, retract the inner sleeve relative to the outer sleeve. Under the action of the linkage mechanism, the bristles on the first support also retract inward relative to the inner sleeve, thus shortening it to a shorter size for easy storage and carrying.

[0008] In some embodiments of this utility model, the linkage mechanism includes a gear and a first rack and a second rack meshing on opposite sides of the gear. The gear is rotatably disposed inside the inner sleeve at the end away from the first support. The first rack is fixedly disposed inside the outer sleeve and extends along the length direction of the outer sleeve. The second rack is fixedly disposed on the first support and extends along the length direction of the inner sleeve.

[0009] In some embodiments of this utility model, the inner sleeve is provided with two parallel clamping plates extending along its length at one end near the outer sleeve. The opposing sidewalls of the two clamping plates are respectively provided with a pivot portion, and the two pivot portions are coaxially arranged. The middle part of the gear is provided with a shaft hole for the two pivot portions to be inserted. The first rack and the second rack are both located between the two clamping plates.

[0010] In some embodiments of this utility model, the width of the first rack and the width of the second rack are adapted to the distance between the two clamping plates.

[0011] In some embodiments of this utility model, each of the two clamping plates is provided with a first guide plate abutting against the back of the first rack and a second guide plate abutting against the back of the second rack on the side wall near the gear. The first guide plate and the second guide plate are used to guide the inner sleeve to move telescopically relative to the outer sleeve and to guide the first support to move telescopically relative to the inner sleeve.

[0012] In some embodiments of this utility model, at least one of the clamping plates is provided with a strip-shaped guide hole extending along its length direction, and a guide block that reciprocates along the strip-shaped guide hole is provided on one side of the end of the first rack. The limiting mechanism includes a first locking part provided at the end of the strip-shaped guide hole away from the first support and a second locking part provided at the guide block and cooperating with the first locking part.

[0013] In some embodiments of this utility model, both clamping plates are provided with the strip-shaped guide hole. The first snap-fit ​​part is a snap-fit ​​protrusion formed on the opposite side walls of the strip-shaped guide hole, and the second snap-fit ​​part is a snap-fit ​​groove formed on the opposite side walls of the guide block. When the snap-fit ​​protrusion is snapped into the snap-fit ​​groove, the guide block abuts against the end of the strip-shaped guide hole to limit the distance by which the inner sleeve extends out of the outer sleeve.

[0014] In some embodiments of this utility model, the sidewalls of the two clamping plates that are opposite to each other are provided with guide ribs extending along the length direction of the inner sleeve, and the inner peripheral wall of the outer sleeve is provided with guide grooves that correspond one-to-one with the guide ribs.

[0015] In some embodiments of this utility model, the limiting mechanism includes a first protrusion located at one end of the guide rib near the outer sleeve, and a second protrusion abutting against the first protrusion at the end of the guide groove. The second protrusion abuts against the first protrusion to restrict the inner sleeve from retracting into the outer sleeve.

[0016] In some embodiments of this utility model, a second support is provided at the end of the outer tube away from the first support, and the second support is used to install the soft rubber massage head.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] See Figures 1 to 4This utility model discloses a telescopic makeup brush, comprising: an outer tube 100, an inner tube 200 telescopically connected to one end of the outer tube 100, and a first support 300 telescopically connected to one end of the inner tube 200 extending beyond the outer tube 100. The first support 300 is used to mount brush bristles. A linkage mechanism 400 is provided between the outer tube 100, the inner tube 200, and the first support 300. The linkage mechanism 400 has an extended state and a retracted state. A limiting mechanism is provided between the inner sleeve 200 and the first support 300 to stabilize the linkage mechanism 400 in the unfolded state; when the linkage mechanism 400 is in the unfolded state, the inner sleeve 200 extends relative to the outer sleeve 100, and the first support 300 extends relative to the inner sleeve 200; when the linkage mechanism 400 is in the retracted state, the inner sleeve 200 retracts relative to the outer sleeve 100, and the first support 300 retracts relative to the inner sleeve 200.

[0031] When using the makeup brush, extend the inner sleeve 200 relative to the outer sleeve 100 until the linkage mechanism 400 is in the unfolded state. Under the action of the linkage mechanism 400, the bristles on the first support 300 also extend outward relative to the inner sleeve 200. The inner sleeve 200 and the outer sleeve 100 form the brush handle, which can be extended to a longer size for easy gripping and use. When storing the makeup brush, retract the inner sleeve 200 relative to the outer sleeve 100 until the linkage mechanism 400 is in the stored state. Under the action of the linkage mechanism 400, the bristles on the first support 300 also retract inward relative to the inner sleeve 200, thereby shortening it to a shorter size for easy storage and carrying.

[0032] See Figure 2 and Figure 4In some embodiments of this utility model, the linkage mechanism 400 includes a gear 410 and a first rack 420 and a second rack 430 meshing with opposite sides of the gear 410. The gear 410 is rotatably disposed inside the inner sleeve 200 at the end away from the first support 300. The first rack 420 is fixedly disposed inside the outer sleeve 100 and extends along the length direction of the outer sleeve 100. The second rack 430 is fixedly disposed on the first support 300 and extends along the length direction of the inner sleeve 200. Understandably, when using the makeup brush, the user holds the outer tube 100 and inner tube 200 with both hands and stretches them. The inner tube 200 extends relative to the outer tube 100, causing the first rack 420 to drive the gear 410 to rotate. Simultaneously, the gear 410 drives the second rack 430 to move away from the first rack 420, thereby causing the first support 300 to extend relative to the inner tube 200. When the linkage mechanism 400 moves to the extended state, the limiting mechanism acts between the outer tube 100 and the inner tube 200, or between the inner tube 200 and the first support 300, to prevent the brush bristles from shortening in size when applied to the face, thus affecting normal use. For storing the makeup brush, see [link to relevant documentation]. Figure 3 When the user applies a certain external force to overcome the limiting mechanism, the inner sleeve 200 retracts relative to the outer sleeve 100. The second rack 430 then drives the gear 410 to rotate in the opposite direction. The gear 410 then drives the first rack 420 to move closer to the second rack 430, thus placing the linkage mechanism 400 in the retracted state. The inner sleeve 200 retracts relative to the outer sleeve 100, and the first support 300 retracts relative to the inner sleeve 200. The linkage mechanism 400 has a simple structure, reducing the difficulty of manufacturing and assembling the makeup brush.

[0033] See Figure 4 and Figure 5 In some embodiments of this utility model, the inner sleeve 200 is provided with two parallel clamping plates 210 extending along its length at one end near the outer sleeve 100. A pivot portion 220 is provided on each of the opposing sidewalls of the two clamping plates 210, and the two pivot portions 220 are coaxially arranged. The gear 410 has a shaft hole 411 in its middle for the two pivot portions 220 to be inserted into. The first rack 420 and the second rack 430 are both located between the two clamping plates 210. This structure not only achieves the rotatable connection of the gear 410 to the inner sleeve 200, but also utilizes the two clamping plates 210 to restrict the movement of the first rack 420 and the second rack 430 along the axial direction of the gear 410, ensuring the reliability of the linkage mechanism 400's operation.

[0034] In some embodiments of this utility model, in order to further improve the stability of the linkage mechanism 400, the width of the first rack 420 and the width of the second rack 430 are adapted to the distance between the two clamping plates 210.

[0035] See Figure 4 and Figure 5 In some embodiments of this utility model, each of the two clamping plates 210 has a first guide plate 230 abutting against the back of the first rack 420 and a second guide plate 240 abutting against the back of the second rack 430 on its sidewalls near the gear 410. The first guide plate 230 and the second guide plate 240 are used to guide the inner sleeve 200 to extend and retract relative to the outer sleeve 100 and to guide the first support 300 to extend and retract relative to the inner sleeve 200. The first guide plate 230 can prevent the first rack 420 from separating from the gear 410 along the radial direction of the gear 410, and the second guide plate 240 can prevent the second rack 430 from separating from the gear 410 along the radial direction of the gear 410, ensuring that the gear 410 is stably meshed with the first rack 420 and the second rack 430.

[0036] See Figure 4 In some embodiments of this utility model, at least one of the clamping plates 210 is provided with a strip-shaped guide hole 250 extending along its length direction. A guide block 260 protrudes from one side of the end of the first rack 420 and reciprocates along the strip-shaped guide hole 250. The limiting mechanism includes a first engaging portion 510 located at the end of the strip-shaped guide hole 250 away from the first support 300 and a second engaging portion 520 located on the guide block 260 and cooperating with the first engaging portion 510. It can be understood that when the inner sleeve 200 extends relative to the outer sleeve 100 to the extended state of the linkage mechanism 400, the first engaging portion 510 and the second engaging portion 520 engage, thereby restricting the relative extension and retraction of the inner sleeve 200 and the outer sleeve 100, ensuring that the makeup brush will not retract relative to the inner sleeve 200 and the outer sleeve 100 due to pressure on the bristles during use.

[0037] See Figure 4 and Figure 5In some embodiments of this utility model, in order to balance the force, both clamping plates 210 are provided with strip-shaped guide holes 250. The first snap-fit ​​part 510 is a snap-fit ​​protrusion formed on the opposite side walls of the strip-shaped guide hole 250, and the second snap-fit ​​part 520 is a slot formed on the opposite side walls of the guide block 260. When the snap-fit ​​protrusion is snapped into the slot, the guide block 260 abuts against the end of the strip-shaped guide hole 250 to limit the distance by which the inner sleeve 200 extends out of the outer sleeve 100, thereby preventing the inner sleeve 200 and the outer sleeve 100 from extending out relative to each other and fixing the maximum length of the brush rod.

[0038] See Figure 4 In some embodiments of this utility model, in order to limit the relative rotation of the inner sleeve 200 and the outer sleeve 100 and further improve the smoothness of the extension and retraction of the inner sleeve 200 relative to the outer sleeve 100, the sidewalls of the two clamping plates 210 that are opposite to each other are provided with guide ribs 270 extending along the length direction of the inner sleeve 200, and the inner peripheral wall of the outer sleeve 100 is provided with guide grooves 110 that correspond one-to-one with the guide ribs 270.

[0039] See Figure 4 In some embodiments of this utility model, the limiting mechanism includes a first protrusion 530 located at one end of the guide rib plate 270 near the outer sleeve 100, and a second protrusion 540 abutting against the first protrusion 530 at the end of the guide groove 110. The second protrusion 540 abuts against the first protrusion 530 to restrict the inner sleeve 200 from retracting into the outer sleeve 100. It can be understood that when the inner sleeve 200 extends out of the first locking portion 510 and the second locking portion 520 relative to the outer sleeve 100 and engages, the first protrusion 530 just passes over the second protrusion 540 and abuts against the side of the second protrusion 540, which also serves to restrict the relative retraction of the inner sleeve 200 and the outer sleeve 100.

[0040] See Figure 2 In some embodiments of this utility model, in order to enrich the functions of the makeup brush, a second support 120 is provided at the end of the outer tube 100 away from the first support 300. The second support 120 is used to install a soft rubber massage head. The soft rubber massage head can be used to spread cosmetics evenly on the skin, and it is also conducive to the skin fully absorbing essential oils and other cosmetics.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
