Abstract
Description
Technical Field
[0001] This utility model relates to the field of beauty product technology, specifically to a reversible butterfly pen holder for nail art pens. Background Technology
[0002] A nail polish pen is a tool used to apply nail polish to nails. Besides having bristles attached to the end of the pen, existing technologies also incorporate nail polish into the pen, eliminating the need for the brush to pick up the polish. For example, the nail polish pen authorized by Chinese Patent Publication No. CN208807723U on May 3, 2019, includes a pen barrel and a brush head; the tip of the pen barrel has a bristle-implanting hole; the brush head consists of multiple bristles, each with an oil-applying end and a connecting end, the bristles being fixed within the bristle-implanting hole via the connecting end, and the bristles extending out of the hole; the brush head is flat; the pen barrel itself has a transparent window with an ultraviolet radiation-proof protective film.
[0003] The existing technology stores nail polish in the hollow cavity of the pen barrel, and transfers the nail polish to the brush head by rotating the upper end of the pen to squeeze the nail polish in the pen barrel onto the brush head. In actual use, this causes the nail polish to be pressed into the movable connection between the pen barrel and the brush head at the same time, resulting in a decrease in the connection strength between the two and the problem of nail polish overflowing from the movable connection between the pen barrel and the brush head. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is:
[0005] 1. Design a reversible butterfly-shaped nail art pen holder, ensuring a reliable and detachable connection between the grip and the pen body during use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a reversible butterfly pen holder nail art pen, comprising a grip, a pen body, and a pen tip, wherein one end of the pen body is inserted into the grip, the pen tip is disposed on the other end of the pen body, and an annular gasket is also provided at the connection between one end of the pen body and the grip.
[0007] The ring-shaped gasket is used to fill the gap between the pen body and the grip when they are inserted, making the connection more stable.
[0008] Optionally, a hemispherical guide surface is provided on one end of the pen body.
[0009] The hemispherical guide surface can effectively guide the pen body into the grip.
[0010] Optionally, a protruding blocking part is also provided at the other end of the spherical guide surface near the pen body.
[0011] The blocking part is used to limit the depth of the pen body inserted into the grip, preventing the pen body from being excessively inserted into the grip, causing damage or making it difficult to pull out.
[0012] Optionally, the external dimensions of the blocking portion match the external dimensions of the gripper near the blocking portion.
[0013] This design ensures consistency between the grip and the pen body.
[0014] Optionally, the pen tip includes a plurality of parallel bristles, one end of which is fixed to the other end of the pen body, and the other end of which is arc-shaped.
[0015] The curved bristles correspond to the curvature of human nails, ensuring even pressure when applying nail polish.
[0016] Optionally, the annular gasket is a metal gasket, and the grip is made of wood.
[0017] Wooden grips fit the human hand better and are easier to adjust to a suitable shape when customizing grips.
[0018] Optionally, an expansion joint is provided on the side of the annular gasket.
[0019] The expansion joint design makes it easier for the metal ring gasket to fit into the groove of the gripper.
[0020] Optionally, the blocking part divides the pen body into a forward insertion part and a reverse insertion part, the dimensions of which correspond to the dimensions of the groove at one end of the grip member.
[0021] The design of the right-side-insertion and reverse-insertion parts allows the grip of this product to be used for holding when inserted correctly and as a pen cap when inserted incorrectly.
[0022] The beneficial technical effects of this utility model are: the addition of a ring-shaped gasket to the split design makes the connection between the grip and the pen body more stable; the arc-shaped bristles correspond to the curvature of human fingernails, which can ensure even pressure when applying nail polish.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0029] Example 1
[0030] Reference Figure 1 , 2 As shown in Figures 3 and 4, a reversible butterfly pen holder nail art pen includes a grip 1, a pen body 2, and a pen tip 3.
[0031] One end of the pen body 2 is inserted into a groove at one end of the grip 1, and the pen tip 3 is located on the other end of the pen body 2. An annular washer 4 is also provided at the connection between one end of the pen body 2 and the grip 1. The annular washer 4 is a metal washer, the grip 1 is made of wood, and the pen body 2 is made of metal. An expansion joint 8 and four rectangular cutouts 7 are provided on the side of the annular washer 4. The expansion joint 8 is used to adjust the outer diameter of the annular washer 4 so that it can be firmly inserted into the grip 1. A protrusion corresponding to the rectangular cutouts 7 can be provided on one end of the pen body 2 to further strengthen the connection between the pen body 2 and the grip 1.
[0032] A hemispherical guide surface 5 is provided on one end of the pen body 2.
[0033] A protruding blocking part 9 is also provided at the other end of the spherical guide surface 5 near the pen body 2.
[0034] The external dimensions of the blocking part 9 are the same as the external dimensions of the gripping part 1 near the blocking part.
[0035] The brush tip 3 includes several parallel bristles, one end of which is fixed to the other end of the brush body 2, and the other end of the bristles is curved. Viewed from above, the other end of the bristles is curved. During the nail art process, when the curved bristles come into contact with the curved nail, the longer bristles in the middle contact the nail first and are gradually pressed to the sides as the brush is pressed down. When the pressure is appropriate, the amount of bristles in the middle and on the sides is approximately equal, resulting in an even application of oil to the nail.
[0036] In use, one end of the pen body 2 is inserted into the groove at one end of the grip 1. The pen body 2 and the grip 1 are connected by the interference fit between the annular washer 4 and the pen body 2. When there is no nail polish in the grip 1 or pressure from squeezing nail polish, the interference fit between the annular washer 4 and the pen body 2 is sufficient to ensure the connection strength during the application of nail polish by the pen tip 3. Therefore, during nail art, the pen tip 3 needs to be dipped into the nail polish for application. When it needs to be replaced, simply hold the pen body 2 and the grip 1 with both hands and pull them apart. This solution is based on the fact that the grip 1 needs to be customized according to the user's grip and work habits.
[0037] Furthermore, a raised decorative element 6 is provided on the blocking part to facilitate the disassembly of the pen body 2 and the grip 1. When the nail art pen is in a brief non-use state and placed on a table, the decorative element 6 and the other end of the grip 1 are in contact with the table, ensuring that the pen tip 3 is suspended in the air and does not come into contact with the table, so as to ensure that the nail polish on the pen tip 3 is not contaminated.
[0038] Specifically, the raised decorative element 6 is shaped like a butterfly, with the wings slightly higher than the center. This design is not only aesthetically pleasing, but also provides stability when placed on a table. The wings and the other end of the grip 1 form a triangular support, preventing the object from rolling, shaking, or tipping over due to uneven surfaces.
[0039] Example 2
[0040] The difference from Embodiment 1 is that a controllable light source, such as an LED light, is installed on the side of the raised decorative element 6 near the brush tip 3. A Nefertory lens is also installed on the light source. The light emitted by the light source is directed towards the brush head to check whether the base coat, colored nail polish, top coat, etc., applied to the nails are even or whether there are any missed areas.
[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
