Abstract
Description
Technical Field
[0001] This utility model is a sanitary tampon that is easy to replace and use, belonging to the field of sanitary tampons. Background Technology
[0002] Tampons, also known as sanitary tampons, are cylindrical cotton tampons, mainly made of cotton, synthetic fibers, or a mixture of the two. They come in sizes ranging from 1 cm to 1.9 cm in diameter and have a string (pull cord) attached to the end. Tampons are made primarily of cotton, synthetic fibers, or both and are inserted into the vagina to absorb menstrual blood during menstruation.
[0003] Chinese patent discloses a tampon that is easy to replace (publication number: CN211512320U), which includes a first pull cord, a connecting cap, a clamping plate, a flexible film, an absorbent body, and a second pull cord. The first pull cord is fixedly connected to the connecting cap, the connecting cap is rotatably connected to the clamping plate, the flexible film is fixedly connected to the clamping plate, and the clamping plate is slidably connected to the absorbent body. Pulling the first pull cord, combined with the pressure of the vaginal wall, causes the flexible film and the clamping plate to detach from the absorbent body under the action of the connecting cap, thereby allowing the absorbent body to be inserted into the body. Then, the clamping plate contracts inward to reduce its diameter, making it easier to pull the clamping plate and the connecting cap out of the body.
[0004] When women with heavy menstrual flow use tampons, the tampons may become saturated and soak through, resulting in a sticky residue when removed. This can make some women reluctant to use the tampons and makes them more difficult to find and remove. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a convenient tampon for easy replacement. This solves the problem that when women with heavy menstrual flow use tampons, the tampons become saturated and sticky, making them difficult to remove and causing some users to resist using them. It also makes finding and removing the tampons more complicated.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tampon that is easy to replace and use, comprising a protective shell, a tampon head, a tampon, an agitator, an auxiliary structure, and a protective soft cover. The tampon head is disposed inside the protective shell, and the bottom of the tampon head is fixed to the tampon. The agitator is disposed inside the protective shell. The inner side of the tampon is fixed to the auxiliary structure. The top of the protective shell is fixed to the protective soft cover. The auxiliary structure comprises a limiting core, a connecting line, and a limiting post. The outer side of the limiting core is fixed to the connecting line. The bottom of the limiting core is vertically fixed to the limiting post. The limiting core is movably embedded inside the tampon. The outer side of the connecting line is connected to the tampon. The lower end of the limiting post is movably connected to the tampon.
[0007] Furthermore, the connecting line has a radius of 3mm and is distributed at both ends of the limiting core.
[0008] Furthermore, the limiting post is cylindrical, and the outer surface of the limiting post is provided with anti-slip texture.
[0009] Furthermore, the protective soft cover is shaped like a flower bud, and the protective soft cover is composed of six separate fan-shaped surfaces.
[0010] Furthermore, the protective shell has a structure that is wider at the top and narrower at the bottom, and anti-slip texture is provided on the lower side of the outer end of the protective shell.
[0011] Advantages: This utility model provides a convenient sanitary tampon for easy replacement. By providing an auxiliary structure on the inside of the tampon, the limiting post inside makes it easy for the user to find, avoiding the cumbersome situation of removing the tampon after it has absorbed moisture. Furthermore, the connecting line on the outside of the limiting core on the inside of the tampon makes it easier for the user to remove the tampon head from the body, thus avoiding the situation where viscous liquid sticks to the hands during the removal process. Attached Figure Description
[0012] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:
[0013] Figure 1 This is a schematic diagram of the structure of this utility model;
[0014] Figure 2 This is a partial front view schematic diagram of the auxiliary structure of this utility model.
[0015] In the diagram: Protective shell-1, tampon head-2, tampon-3, booster-4, auxiliary structure-5, protective soft cover-6, limiting core-51, connecting line-52, limiting post-53. Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] Please see Figure 1 This utility model provides an improved tampon that is easy to replace and use, including a protective shell 1, a tampon head 2, a tampon 3, a pusher 4, an auxiliary structure 5, and a protective soft cover 6. The tampon head 2 is provided inside the protective shell 1, and the bottom of the tampon head 2 is fixed to the tampon 3. The pusher 4 is provided inside the protective shell 1, and the inner side of the tampon 3 is fixed to the auxiliary structure 5. The top of the protective shell 1 is fixed to the protective soft cover 6. The pusher 4 makes it easier for the user to push the tampon 3 into the body.
[0018] Please see Figure 2 This utility model provides an improved sanitary tampon that is easy to replace. The auxiliary structure 5 includes a limiting core 51, a connecting line 52, and a limiting post 53. The outer side of the limiting core 51 is fixed to the connecting line 52 as a whole. The bottom of the limiting core 51 is vertically fixed to the limiting post 53. The limiting core 51 is movably embedded inside the tampon 3. The outer side of the connecting line 52 is connected to the tampon 3. The lower end of the limiting post 53 is movably connected to the tampon 3. The setting of the limiting post 53 makes it easier for the user to pull the tampon 3 out of the body.
[0019] The work process is as follows:
[0020] 1. The user can first insert the protective shell 1 into the vagina. Then, the user can use the index finger to push the pusher 4 into the protective shell 1, thereby pushing the tampon 3 inside the protective shell 1 out from the anti-slip soft cover 6 until the tampon 3 is inserted into the vagina. Then the pusher 4 and the protective shell 1 can be removed from the vagina to complete the use.
[0021] 2. After use, the user can pull the tampon 3 out of the body by finding the limiting post 53. During this process, the connecting line 52 connected to the inside of the limiting core 51 will break in sequence, which makes it easier to pull the tampon 3 out of the body and avoids sticky blood on the hands.
[0022] The above describes the basic principles, main features, and advantages of this utility model. All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings.
