Description
Technical Field
[0001] This invention relates to the field of makeup brushes, and more specifically to a retractable makeup brush with a cap that is easier to attach. Background Technology
[0002] Makeup brushes are essential makeup tools that are used frequently during makeup application. Makeup brushes typically have a cap to protect the brush head; however, traditional caps can easily come into contact with the bristles during installation. Special care must be taken when installing the cap, as improper placement can cause the bristles to fold over. Utility Model Content
[0003] To address the problems of existing technologies, this utility model provides a telescopic makeup brush with an easier-to-install cap, including a telescopic sleeve that extends to the brush head, facilitating the installation of the cap and effectively avoiding installation difficulties and brush head bristle damage caused by the cap contacting the brush head during installation.
[0004] A retractable makeup brush with an easier-to-install cap, comprising a brush handle and a cap, characterized in that,
[0005] The brush rod includes a fixed brush rod and a movable brush rod, with the movable brush rod sleeved on both sides of the fixed brush rod;
[0006] A cap is fitted onto the outer end of the movable brush rod, and the cap is connected to the movable brush rod by an interference fit.
[0007] When closing the cap, manually pull the movable brush rod outward until it reaches the preset length and then stop. Then, assemble the cap onto the movable brush rod. During assembly, the cap and the movable brush rod will retract inward with external force until they can no longer retract. Finally, use external force to fully assemble the cap and the movable brush rod.
[0008] When opening the lid, the cap and the movable brush rod are pulled out by an outward force until they reach the preset position and then stop extending and retracting. The cap is then removed from the movable brush rod by external force, and the movable brush rod is then retracted downwards until it can no longer be retracted. The lid opening is then complete, and the makeup brush can be used normally.
[0009] The brush rod has brush heads at both ends, and the preset stop of the extension and retraction of the movable brush rod is the outermost edge of the brush head.
[0010] Furthermore, the brush rod also includes an inner rod, which is located inside the movable brush rod;
[0011] A cavity is provided between the fixed brush rod and the inner rod for the movement of the movable brush rod.
[0012] Furthermore, the inner rod includes a left inner rod and a right inner rod;
[0013] A partition is provided between the left inner rod and the right inner rod.
[0014] Furthermore, the inner rod includes a first limiting part and a second limiting part;
[0015] The first limiting part is located on the side of the inner rod near the partition, and the second limiting part is located on the other side;
[0016] The first limiting part and the second limiting part are provided by protruding outward on the surface of the inner rod.
[0017] Furthermore, the height of the first limiting part protrusion is less than the height of the second limiting part protrusion;
[0018] The first limiting part has an inclined surface.
[0019] Furthermore, the inner rod is provided with a hollowed-out groove, which is set vertically along the inner rod.
[0020] Furthermore, the movable brush rod includes a tail rod located at the end and a rib located on the surface of the movable brush rod and protruding from the surface;
[0021] The diameter of the tail rod is smaller than the diameter of the movable brush rod;
[0022] The diameter of the protruding rib is larger than the inner surface diameter of the fixed brush rod.
[0023] Furthermore, during the extension and retraction of the movable brush rod,
[0024] The tail rod is relatively tight when it is pulled out through the first limiting part of the inner rod in the first stage. In the second stage, when the tail rod moves to the position of the hollow groove, the hollow groove is compressed and deformed, and the movable brush rod is pulled out more loosely.
[0025] The movable brush rod extends from tight to loose, and conversely, retracts from loose to tight, thus preventing mistaken insertion.
[0026] Furthermore, the brush head is mounted on the inner rod;
[0027] The brush head and the inner rod are connected by a threaded rotation.
[0028] Furthermore, the brush handle is made of plastic, and the cap is also made of plastic.
[0029] Furthermore, the brush rod has a base inside, and the inner rod is sleeved on the base.
[0030] Furthermore, the fixed brush rod and the inner rod are integrally formed by injection molding.
[0031] Furthermore, the fixed brush rod is divided into two independent cavities by a partition.
[0032] The advantages of this invention compared to the prior art are:
[0033] This invention features a movable brush rod inside the brush handle. When installing the cap, the movable brush rod can be pulled along with a rope to the brush head position, and the cap can be fitted onto the movable brush rod and installed using external force. This effectively avoids the problem of brush bristles being bent or damaged due to contact between the brush head bristles and the cap during the installation process of traditional caps.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] like Figure 1-6 As shown, a telescopic makeup brush with an easier-to-install cap includes a brush handle 1 and a cap 2. The brush handle 1 includes a fixed brush handle 111 and a movable brush handle 113. The movable brush handle 113 is sleeved on both sides of the fixed brush handle 111. The cap 2 is sleeved on the outer end of the movable brush handle 113. The cap 2 is connected to the movable brush handle by an interference fit. The movable brush handle serves as a guide during cap assembly, facilitating cap installation.
[0043] When the cap 2 is closed, manually pull the movable brush rod outward until it reaches the preset position and then stop. Then assemble the cap with the movable brush rod. During assembly, the cap and movable brush rod will retract inward with external force until they can no longer retract. Then, use external force to fully assemble the cap with the movable brush rod. Generally, the brush head is relatively fluffy and soft. After a period of use, the bristles on the brush head will expand outward. In this case, when the cap is closed, pull the movable brush rod upward so that the bristles are inside the movable brush rod. Then assemble the cap and movable brush rod. This can effectively solve the problem of the cap contacting the bristles when closing, which would cause the bristles to fold and be damaged.
[0044] When the cap 2 is opened, the cap and the movable brush rod are pulled out by an outward force until they reach the preset position and then stop extending and retracting. The cap is then removed from the movable brush rod by external force, and the movable brush rod is then retracted downward until it can no longer be retracted. The cap opening is then complete, and the makeup brush can be used normally.
[0045] The brush rod 1 shown has brush heads 3 at both ends. The preset extension and retraction of the movable brush rod 113 is the outermost edge of the brush head. The maximum movement distance of the movable brush rod should be enough to keep the bristles inside the movable brush rod, so as to avoid contact with the cap when the cap is closed.
[0046] The brush rod 1 shown also includes an inner rod 112, which is located inside the movable brush rod 113. A cavity 211 for the movable brush rod to move is provided between the fixed brush rod 111 and the inner rod 112. There is a cavity for the movable brush rod to move between the fixed brush rod and the inner rod. The movable brush rod can move between the fixed brush rod and the inner rod under the action of external force, that is, by pulling or pressing the outermost side of the movable brush head.
[0047] The inner rod 112 shown includes a left inner rod and a right inner rod. A partition 212 is provided between the left inner rod and the right inner rod, which divides the inner rod into two identical parts.
[0048] The inner rod 112 shown includes a first limiting part 6 and a second limiting part 7. The first limiting part 6 is located on the side of the inner rod 112 near the partition 212, and the second limiting part 7 is located on the other side. The first limiting part 6 and the second limiting part 7 are provided by protruding outward on the surface of the inner rod 112. The first limiting part is used to restrict the movement space of the movable brush rod. When the movable brush rod contacts the first limiting part, the cavity width is reduced and the extension and retraction of the movable brush rod is more difficult. The second limiting part is used to limit the movement distance of the movable brush rod. The lower limiting part is located on the end of the inner rod, restricting the movable brush rod to only extend and retract to the second limiting part.
[0049] The height of the first limiting part 6 is less than the height of the second limiting part 7. The first limiting part 6 has an inclined surface 213. The first limiting part is located inside the brush rod to limit the width of the cavity. The second limiting part is located outside the brush rod to limit the extension and retraction distance of the movable brush rod. The second limiting part can also serve as a force point. When the movable brush rod is pulled out, the force applied to the second limiting part makes it easier to pull out the movable brush rod.
[0050] The inner rod 112 shown is provided with a hollow groove 9. The hollow groove 9 is set vertically along the inner rod 112. The hollow groove is used to make the extension and retraction of the movable brush rod smoother. After the movable brush rod moves to the hollow groove, the hollow groove deforms downward, and the resistance of the movable brush rod is reduced.
[0051] The movable brush rod 113 shown includes a tail rod 4 at the end and a rib 5 on the surface of the movable brush rod that protrudes from the surface. The diameter of the tail rod 4 is smaller than the diameter of the movable brush rod 113, and the diameter of the rib 5 is larger than the inner surface diameter of the fixed brush rod 111.
[0052] During the extension and retraction process, the movable brush rod 113 shown is relatively tight when it is pulled outward by the first limiting part of the inner rod in the first stage. In the second stage, when the tail rod moves to the position of the hollow groove, the hollow groove is deformed by pressure, and the movable brush rod is pulled out more loosely. The movable brush rod shown is pulled out from tight to loose. Conversely, the movable brush rod retracts from loose to tight, which is a foolproof setting.
[0053] The brush head 3 shown is mounted on the inner rod 112, and the brush head 3 and the inner rod 112 are connected by a threaded rotation.
[0054] The brush handle 1 shown is made of plastic, and the cap 2 shown is also made of plastic. The brush handle and the inner handle are fixed by injection molding.
[0055] The brush rod 1 shown has a base 10 inside, and the inner rod 112 is sleeved on the base 10.
[0056] The fixed brush rod 111 shown is divided into two independent cavities by a partition 212, and an inner rod and a movable brush rod are installed in the cavity respectively.
[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
