Technical Field
[0001] This utility model relates to the field of beauty device technology, specifically to a beauty injection needle and a beauty injection device. Background Art
[0002] With the continuous development of cosmetic injection techniques, the requirements for injection needles are also increasing. Blunt needles, due to their blunt, flexible, and non-sharp nature, significantly reduce the risk of puncturing blood vessels and nerves during injection, making them particularly suitable for injections in large areas, deep layers, or areas with complex anatomical structures. However, blunt needles also have some significant drawbacks, such as difficulty in superficial subcutaneous injections, the need for advanced anatomical knowledge and operational skills to avoid damage to surrounding tissues, and the potential for greater pain when penetrating the skin. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention aims to provide a cosmetic injection needle and a cosmetic injection device, thereby resolving the technical problem that cosmetic injections in the prior art can easily cause strong pain.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example
[0022] like Figure 1 As shown, this embodiment provides a cosmetic injection needle, including:
[0023] Needle hub 100: has a needle hub opening 110 for connection with the syringe body. The needle hub 100 is made of plastic material to improve grip and sealing.
[0024] Needle 200: Includes a connecting section 210 and a needle tip section 220. The end of the needle tip section 220 has a smooth beveled surface, on which an injection port 230 is formed. The injection port 230 is an elliptical hole that is concave and transitions to the inner wall by an arc, with a major axis less than or equal to 2 mm, to control the flow rate and direction of the liquid, reduce liquid spraying, and improve injection accuracy. The needle 200 is made of stainless steel to ensure strength and corrosion resistance. Specifically, this embodiment further defines the angle formed by the smooth beveled surface and the length direction of the needle 200. This angle A is preferably 5-80°, and optimally 15°, to balance penetration and comfort during injection. Example
[0025] Based on Embodiment 1, this embodiment adds a convex arc-shaped structure 240 to the beveled surface. This structure is seamlessly connected to the arc of the beveled surface, with a convex height not exceeding 0.5mm. This reduces the speed at which the needle tip penetrates the skin, thereby minimizing skin irritation and damage, and preventing excessive injection force from puncturing blood vessels. Furthermore, the connecting segment 210 is integrally formed with the needle tip segment 220. The length of the connecting segment 210 is greater than that of the needle tip segment 220, and the flexibility of the needle tip segment 220 is greater than or equal to that of the connecting segment 210, to adapt to the needs of different injection sites. Example
[0026] To improve injection accuracy, this embodiment features multiple evenly spaced graduation lines on the outer circumferential surface of the needle 200. The graduation lines may contain a luminescent material for easy operation in low-light conditions, and their width is less than or equal to 1 mm to ensure both aesthetics and precision. Example
[0027] like Figure 2 As shown, this embodiment also provides a cosmetic injection device, including a syringe body 300 and the cosmetic injection needle described in any of the above embodiments. The syringe body 300 and the cosmetic injection needle are detachably connected for easy replacement and cleaning. This cosmetic injection device mainly includes the syringe body 300 and the aforementioned cosmetic injection needle. As the main body of the device, the syringe body 300 integrates key functions such as drug storage, pressure control, and injection volume adjustment, ensuring the accuracy and controllability of the injection process.
[0028] In actual use, users simply need to correctly connect the selected cosmetic injection needle to the syringe body 300, and then adjust the injection parameters as needed, such as injection volume and injection speed, to begin the injection procedure. Because the cosmetic injection needle uses a fully enclosed needle tip design, a side injection port layout, and flexible materials, the entire injection process is safer and more comfortable, reducing patient pain and the risk of adverse reactions.
[0029] In addition, the syringe body 300 can also be equipped with a display screen, buttons and other operating interfaces, as well as an alarm system. The injection status is monitored through a liquid level sensor, the display screen is used to show the injection status, receive user instructions, and issue alarms in a timely manner when abnormal situations occur, further improving the safety and ease of use of the device.
[0030] Based on this, the cosmetic injection needle of this application includes a needle hub and a needle tube. The needle hub includes a needle hub opening, and the needle tube includes a connecting section connected to the needle hub and a needle tip section connected to the connecting section. The end of the needle tip section away from the needle hub has a smooth beveled surface, and the smooth beveled surface has an injection port. The injection port communicates with the needle hub opening through the needle tube. The flexibility of the needle hub is less than that of the needle tube. This more precise smooth needle tip design allows for accurate control of the injection layer and depth during injection, reducing complications and pain caused by inaccurate injection layers.
[0031] Obviously, the above are only preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
