Abstract
Description
Technical Field
[0001] This utility model relates to the field of cosmetic brush technology, and more specifically to a self-dispensing cosmetic brush with a metal brush holder. Background Technology
[0002] Makeup pens, as a common makeup tool, are widely used for applying eyeliner, eyebrows, and other detailed makeup looks. They are favored by consumers due to their portability, flexibility, and precision. As makeup products become more refined and professional, self-dispensing liquid makeup pens, with their ability to continuously and evenly deliver liquid cosmetics, are gradually becoming one of the mainstream products in the market.
[0003] However, most existing cosmetic brush holders are made of plastic, with the brushes typically fixed to the ends of the plastic holder only through insertion or pressing. This structure has several drawbacks in practical use: due to the limited strength and rigidity of plastic, the bond between the brush and the holder is weak. Under repeated use or external force, the grip is unstable, easily leading to the brush loosening or even falling off, affecting the product's lifespan and safety. Furthermore, existing plastic brush holders usually only clamp the base of the brush for a short distance, resulting in insufficient overall brush stability and limited brush elasticity during use, affecting the smoothness and feel of the strokes. Therefore, how to improve the brush's elasticity and stability while ensuring secure fixation, and enhance the overall structural strength and usability, has become a pressing technical problem to be solved in this field. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a self-dispensing cosmetic pen with a metal brush holder.
[0005] A self-dispensing cosmetic pen, comprising:
[0006] The main body contains a water-guiding core and a liquid cosmetic product.
[0007] A pen tip assembly, comprising a brush and a metal brush holder, wherein the metal brush holder is located within the main body, the head of the metal brush holder extends beyond the main body, and the head of the metal brush holder has a gradually flattened clamping section for clamping the brush, and a conveying channel is formed inside the metal brush holder, passing through both ends of the metal brush holder.
[0008] The cosmetics within the main body are delivered to the pen tip assembly via the water-guiding core.
[0009] Furthermore, the metal brush holder is made of aluminum.
[0010] Furthermore, the metal brush holder is made of copper.
[0011] Furthermore, the metal brush holder is a zinc-iron alloy component.
[0012] Furthermore, the metal brush holder also includes a lower body portion in the shape of a cylindrical tube, through which the water-guiding core passes, and the end of the water-guiding core is inserted into the brush.
[0013] Furthermore, it also includes fasteners, one end of which is inserted into and fixed to the metal brush holder, and the other end of which is fixed to the main body, through which the water guide core passes.
[0014] Furthermore, the inner wall of the lower part of the metal brush holder is provided with protrusions, which hold the fasteners in place. The structure is reasonable, and the fixation is stable and reliable.
[0015] Furthermore, the fastener includes an insertion section and a protruding section. The insertion section is a hollow tube and is inserted into the lower part of the metal brush holder. The protruding section is provided with a buckle, and the fastener is fixed to the main body through the buckle.
[0016] Furthermore, the end of the main body is provided with a receiving cavity for installing the pen tip assembly, and the outer wall of the lower part of the metal brush holder is in contact with the inner wall of the receiving cavity.
[0017] The main body has a liquid storage cavity, in which cosmetics are placed, and one end of the water inlet extends into the liquid storage cavity.
[0018] The following benefits can be achieved by using this utility model: The structure of this utility model is reasonable. The brush is held by a metal brush holder of a certain length. The holding length is longer than that of the existing plastic brush holder for fixing the brush bristles. It is firm and reliable. At the same time, the brush is elastic during use. In addition, the metal brush holder that extends out of the brush head has a metallic texture, resulting in a good makeup experience. Attached Figure Description

[0024] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1
[0025] The self-dispensing cosmetic pen described in this embodiment, such as... Figure 1 , Figure 2 As shown, it includes a main body and a pen tip assembly. The main body has a liquid reservoir containing liquid cosmetic products.
[0026] The main body also includes a water-guiding core 3, one end of which extends into the liquid storage chamber. The cosmetics in the main body are transported to the pen tip assembly via the water-guiding core 3.
[0027] The pen tip assembly includes a brush 1 and a metal brush holder 2, the structure of which is as follows: Figure 3 As shown, the metal brush holder 2 can be made of aluminum, copper, or zinc-iron alloy. In this embodiment, aluminum is selected.
[0028] The end of the main body is provided with a receiving cavity 51 for mounting the pen tip assembly. The receiving cavity 51 is located inside the pen tube 5, such as... Figure 5 As shown, the accommodating cavity 51 is in the shape of a straight hole.
[0029] The metal brush holder 2 is located within the accommodating cavity 51 of the main body. The head of the metal brush holder 2 extends beyond the main body, and the head of the metal brush holder 2 has a gradually flattened clamping section 22 for clamping the brush. A conveying channel is formed inside the metal brush holder 2, which runs through both ends of the metal brush holder 2.
[0030] The metal brush holder 2 also includes a lower body 23 in the shape of a cylindrical tube. The water-guiding core 3 passes through the lower body 23 of the metal brush holder 2, and the end of the water-guiding core 3 is inserted into the brush 1. The water-guiding core 3 conveys the cosmetic to the brush tip assembly through the hollow channel.
[0031] In this embodiment, the clamping section 22 is formed by flattening the hollow tubular lower body portion 23.
[0032] The main body also includes fasteners 6, the structure of which is as follows: Figure 5 As shown, the fastener 6 includes an insertion section 61 and a protruding section 62. The insertion section 61 is a hollow tube and is inserted into the lower body 23 of the metal brush holder 2. The protruding section 62 is provided with a buckle 63, and the fastener 6 is fixed to the main body through the buckle 63. The water guide core 3 passes through the fastener 6 and then contacts the brush 1.
[0033] Meanwhile, a protrusion 21 is provided on the inner wall of the lower part 23 of the metal brush holder, and the protrusion 21 holds the fastener 6. In this embodiment, the protrusion 21 can be formed by a dotting process. The protrusion 21 also serves to fix the metal brush holder 2. Example 2
[0034] The structure of this embodiment is the same as that of embodiment 1. The difference from embodiment 1 is that there is no fastener 6 in this embodiment, and the fixing method of the metal brush holder 2 is different.
[0035] In this embodiment, the outer wall of the lower part of the metal brush holder 2 is attached to the inner wall of the accommodating cavity. The attachment of the two restricts the lateral sway of the metal brush holder 2. At the same time, multiple protrusions 21 are formed on the inner wall of the lower part 23 of the metal brush holder through a dotting process. The protrusions 21 hold the fastener 6, restricting the axial movement of the metal brush holder 2, thereby achieving the effect of fixing the metal brush holder 2.
[0036] The above are preferred embodiments of the present utility model and do not limit the scope of protection of the present utility model. Any modifications and improvements made by those skilled in the art based on the design concept of the present utility model should be considered within the scope of protection of the present utility model.
