Abstract
Description
Technical Field
[0001] This utility model specifically relates to a triangular iron brush handle for eyelashes. Background Technology
[0002] A mascara brush is an important tool for applying makeup to eyelashes. It is used to brush eyelashes and, when used with mascara, can make eyelashes thicker and longer. Most mascara brushes on the market are made of plastic bristles. Plastic bristles are easy to manufacture and can be made into various shapes. However, plastic mascara brushes have a drawback: after prolonged use, they will deform and the effect will be less than ideal. In order to brush eyelashes better, you can only replace them with new mascara brushes, which increases the cost of use.
[0003] In order to solve the above problems, this utility model is hereby proposed. Utility Model Content
[0004] The purpose of this invention is to provide a triangular iron brush handle for eyelashes.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A triangular iron brush arm mascara includes a blow bottle, a cap, an inner plug, a brush arm, and an inner cap. The inner cap has an inner cavity, and the brush arm is connected to the inner cavity of the inner cap. The inner cap is located inside the cap, and the inner plug is located inside the blow bottle. The inner plug has a perforated structure, and the brush arm passes through the perforated structure and is located inside the blow bottle. The brush arm includes a connecting part and a brush arm body, and the brush arm body is a triangular iron brush structure.
[0007] Preferably, the brush bar body includes a plurality of continuous spiral brush surfaces and a top brush surface.
[0008] Furthermore, a cutting surface is provided on the side of the spiral brush surface.
[0009] Preferably, there are multiple cutting surfaces, which are evenly distributed around the circumference of the spiral brush surface.
[0010] Furthermore, there are three cutting surfaces.
[0011] Preferably, the inner wall of the inner cavity of the inner cover is provided with an internal thread structure.
[0012] Furthermore, the blown bottle has an internal cavity structure, the inward contraction of the blown bottle forms a cavity opening connection, and the outer side of the cavity opening connection has an external thread structure, the external thread structure of the blown bottle being compatible with the internal thread structure of the inner cap.
[0013] Preferably, the inner plug includes a limiting platform and a limiting step; the inner plug is engaged inside the cavity connection of the blown bottle, and the limiting platform and the limiting step are engaged on the upper and lower sides of the cavity connection.
[0014] Beneficial technical effects:
[0015] This invention features a triangular brush handle made of iron, which is resistant to deformation and allows for easy cleaning after use, ensuring both cleanliness and durability. The pointed tip design easily reaches even the smallest lashes, such as those at the corners and outer edges of the eyes, making it particularly suitable for those with double eyelids, small eyes, or short lashes, preventing missed areas. The multi-angle application using the triangular iron brush head allows for adjustment of the angle using different facets, evenly coating each lash and improving makeup application efficiency.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0027] like Figure 1-7 As shown, a triangular iron mascara brush includes a blow bottle 5, a cap 1, an inner plug 3, a brush handle 4, and an inner cap 2. The inner cap 2 has an inner cavity, and the brush handle 4 is connected to the inner cavity of the inner cap 2. The inner wall of the inner cavity of the inner cap 2 has an internal thread structure, and the inner cap 2 is located inside the cap 1. The inner plug 3 is located inside the blow bottle 5 and has a perforated structure, through which the brush handle 4 passes and is located inside the blow bottle 5.
[0028] The blown bottle 5 has a cavity structure 52 inside. The inward shrinkage of the blown bottle 5 forms a cavity opening connection part 51. The outer side of the cavity opening connection part 51 is provided with an external thread structure. The external thread structure of the blown bottle 5 is adapted to the internal thread structure of the inner cover 2 to achieve a fixed connection between the inner cover 2 and the blown bottle 5.
[0029] The brush handle 4 includes a connecting part 41 and a brush handle body 42, the brush handle body 42 being a triangular iron brush structure.
[0030] The triangular brush head features a triangular metal brush structure: the pointed tip design allows it to easily reach the finest areas of the eyelashes, such as the inner corners and outer corners of the eyes, making it especially suitable for people with double eyelids, small eyes, or short eyelashes, preventing missed areas from being coated.
[0031] The triangular brush structure allows for multi-angle application, utilizing the different facets of the brush head to adjust the angle and evenly coat each eyelash, improving makeup application efficiency.
[0032] The triangular iron brush has a rigid brush head, which can control the amount of cream, making it less likely to leave too much cream behind, and it can be applied more evenly, making it suitable for beginners.
[0033] The brush handle body 42 has a triangular cross-section and is made of iron. The iron material used in the brush handle body 42 makes it less prone to deformation, allowing for timely cleaning after use and ensuring it remains clean without easily deforming.
[0034] The brush body 42 includes several continuous spiral brush surfaces 43, a tip brush surface 44, and a semi-circular tip 46. The tip treatment details include using the pointed end of the triangular brush head to gently brush the lower lashes or short lashes at the inner corner of the eye, precisely without getting any on the eyelid.
[0035] The spiral brush surface 43 has a cutting surface 45 on its side. The spiral brush surface 43 with the cutting surface 45, combined with the cutting surface, can better apply mascara.
[0036] There are multiple cutting surfaces 45, which are evenly distributed around the circumference of the spiral brush surface 43.
[0037] In this embodiment, there are 3 cutting surfaces 45.
[0038] The inner plug 3 includes a limiting platform 31 and a limiting step 32. The inner plug 3 is locked inside the cavity connection part 51 of the blown bottle 5, and the limiting platform 31 and the limiting step 32 are locked on the upper and lower sides of the cavity connection part 51 to prevent the inner plug 3 from slipping out of the blown bottle 5.
[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
