Description

Technical Field

[0001] This utility model relates to the technical field of cosmetic brushes, and specifically to a water-guiding structure used in cosmetic brushes. Background Technology

[0002] Makeup brushes are tools used for applying makeup, and they come in various types and have different uses. They are typically used to draw and modify facial features, such as lips, eyelids, and eyebrows. One type of makeup brush is the TANK brush, which uses a liquid formula and employs capillary action, where a core acts as a guide for the liquid. Specifically, one end of the core contacts the liquid in the brush barrel, and the other end contacts the brush tip. This allows the liquid to be guided from the barrel to the tip, enabling the brush to be used to draw on the skin. However, with advancements in technology, to enhance the appearance of the makeup, pearlescent powder is often added to the liquid. This pearlescent powder can easily clog the core, preventing the liquid or pearlescent powder from reaching the brush tip properly. Summary of the Invention

[0003] The purpose of this invention is to provide a water-guiding structure for a cosmetic pen. By setting up water-guiding groove one and water-guiding groove two, liquid containing pearl powder can move along water-guiding groove one and water-guiding groove two from one end of the water-guiding core to the other end until the pen tip, thereby avoiding clogging. Thus, it solves the problem that liquid containing pearl powder easily causes clogging of the water-guiding core.

[0004] The purpose of this utility model is achieved as follows:

[0005] The water-guiding structure for a cosmetic pen includes a water-guiding core and a diverter seat. The diverter seat has a channel in the middle, and the inner wall of the channel is provided with several protrusions. A water-guiding groove is provided between two adjacent protrusions.

[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0032] like Figures 1-9 As shown, the water-guiding structure for a cosmetic pen includes a water-guiding core 4 and a diverter seat 5. A channel 51 is provided in the middle of the diverter seat 5, and a number of protrusions 52 are provided on the inner wall of the channel 51. A water-guiding groove 53 is provided between two adjacent protrusions 52.

[0033] Meanwhile, the water-guiding core 4 includes a connecting post 41 and a connecting part 42 disposed on the connecting post 41. The connecting part 42 is used to connect with the pen tip 3. The connecting part 42 is provided with a second water-guiding groove 43 corresponding to the first water-guiding groove 53. The connecting post 41 is located in the channel 51 to avoid communication between the first water-guiding grooves 53.

[0034] Therefore, in actual use, the connection post 41 is located in the channel 51 to avoid communication between the water inlet troughs 53, so that each water inlet trough 53 is independent. Through the arrangement of water inlet troughs 53 and water inlet trough 43, the liquid with pearlescent powder can move from one end of the water inlet core 4 to the other end and to the pen tip 3 along the water inlet troughs 53 and water inlet 43, thus avoiding clogging.

[0035] The widths of the openings of the first water inlet 53, the first protrusion 52, and the second water inlet 43 can all be adjusted according to actual conditions to accommodate liquids of different concentrations. Similarly, the depths of the first and second water inlets 53 and 43 can also be adjusted to accommodate liquids of different concentrations. Furthermore, the water inlet core 4 and the pen tip 3 are connected by an insert, and the shape of the water inlet core 4 can be varied, not limited to the shape shown in the attached diagram. That is, the connecting post 41 and the connecting part 42 can be integrally formed or separately assembled. The shapes of the first water inlet 53 and the first protrusion 52 are not limited to straight lines; other shapes are possible, but straight lines are preferred because they are easier to process.

[0036] like Figures 2-5 and Figures 8-9 As shown, the channel 51 includes a water intake section 512 and a connecting section 511. The inner wall of the water intake section 512 is provided with a first protrusion 52 and a first water intake groove 53. The inner wall of the connecting section 511 is provided with a plurality of second protrusions 56. The bottom of the connecting part 42 abuts against the first protrusion 52. The second protrusions 56 are staggered with the first protrusion 52 and located in the second water intake groove 43.

[0037] Therefore, in actual use, by placing the connecting post 41 inside the channel 51 and abutting the bottom of the connecting part 42 against the first protrusion 52, the second protrusion 56 is adapted to the second water inlet channel 43, thereby realizing the connection between the water inlet core 4 and the diverter seat 5.

[0038] Furthermore, the protrusion 56 prevents relative rotation between the water inlet core 4 and the diverter seat 5, thus avoiding mismatch between the water inlet channel 56 and the water inlet channel 43. The bottom of the connecting part 42 abuts against the protrusion 52, thereby limiting the height position.

[0039] Meanwhile, to avoid interference with the flow of liquid caused by the second protrusion 56, the inner diameter of the connecting section 511 is set to be larger than the inner diameter of the water inlet section 512, and the thickness of the second protrusion 56 is set to be smaller than the depth of the water inlet channel 43.

[0040] like Figure 6As shown, the structure of the connecting part 42 is as follows: First, the connecting part 42 is provided with a gathering part 47 at one end near the pen tip 3, and the horizontal cross-sectional area of ​​the gathering part 47 gradually decreases towards the pen tip 3, thereby facilitating insertion with the pen tip 3. Moreover, the structure of the second water channel 43 is as follows: First, the connecting part 42 is provided with several protruding strips 44 on the outer side below the gathering part 47, and the second water channel 43 is provided between two adjacent protruding strips 44.

[0041] Meanwhile, the structure of the protrusion 3 44 is as follows: First, the protrusion 3 44 includes a gathering section 45 and an installation section 46, and the installation section 46 is located in the channel 51 and abuts against the protrusion 1 52. The thickness of the gathering section 45 is less than the thickness of the installation section 46 and gradually decreases towards the pen tip 3.

[0042] like Figures 2-5 As shown, the structure of the diversion seat 5 is as follows: First, several diversion plates 57 are provided on the outside of the diversion seat 5, and a groove 58 is provided between two adjacent diversion plates 57. The diversion seat 5 is provided with a groove rail 59 for connecting several grooves 58, and the diversion seat 5 is provided with a side opening 55 for connecting the groove rail 59 and the channel 51.

[0043] The side opening 55 is used for the flow of liquid and gas, thereby balancing the air pressure inside and outside the flow divider 5 and allowing the liquid to be divided along the flow divider plate 57. In addition, the flow divider 5 is also provided with a second groove 50, which is used to connect several grooves 58. The second groove 50 is adapted to the grooves 58 and the first groove 59 to better balance the air pressure inside and outside the flow divider 5 and to divide the flow.

[0044] like Figures 7-9 As shown, it also includes a pen barrel 1, and an inner rod 6 is provided on the pen barrel 1. One end of the inner rod 6 is located inside the pen barrel 1 and is provided with a tail plug 7. The other end of the inner rod 6 is provided with a pen tip 3.

[0046] Meanwhile, the structure between the inner rod 6 and the diverter seat 5 is as follows: First, the inner wall of the inner rod 6 is provided with a step 63 and a convex ring 64, and the bottom of the diverter seat 5 abuts against the convex ring 64. Furthermore, the outer side of the diverter seat 5 is provided with a protrusion 54, and the top of the protrusion 54 abuts against the step 63.

[0047] Therefore, in actual use, the position of the diverter seat 5 is limited by the setting of step 63 and convex ring 64.

[0048] Secondly, the pen tip sleeve 8 is fitted onto the outside of the pen tip 3, and the bottom of the pen tip sleeve 8 is fitted onto the top outside of the diverter seat 5. Therefore, in actual use, the pen tip sleeve 8 is used to connect the pen tip 3 and the diverter seat 5, thereby stabilizing the connection between the pen tip 3 and the water inlet core 4.

[0049] Furthermore, a side groove 81 is provided on the outer side of the pen tip cap 8 to facilitate the flow of gas and thus balance the air pressure inside and outside the inner rod 6.
