In this embodiment, preferably, the inner core 15 of the tampon is a temperature-sensitive diatomaceous earth gel containing water, which slowly releases water at 36°C to 37.7°C close to the human body temperature to balance the excessive water absorption capacity of the middle layer and the outer layer to prevent skin dryness and damage;
[0035] The preparation process of wormwood fiber powder includes:
[0036] 1: Wash the stems and leaves of mugwort to remove the dirt on the surface;
[0037] 2: Air-dry the wormwood at a temperature of 75-80°C to remove moisture and retain the volatile oil in the wormwood;
[0038] 3: Use a grinder to grind the dried wormwood stems and leaves to obtain wormwood powder;
[0039] 4: Mix the wormwood powder with the dispersant, thickener, solvent, antioxidant and water in proportion, stir thoroughly to dissolve, and filter and defoam to make wormwood pulp;
[0040] 5. Prepare wormwood pulp into wormwood fiber filaments or staple fibers by dry spinning;
[0041] 6. Washing the spun wormwood fiber;
[0042] 7: Drying the washed wormwood fiber;
[0043] 8: Cut the dried wormwood fiber into the required length and shape;
[0044] The water absorbing factor adopts chitosan grafted polyacrylic acid super absorbent resin, and its preparation method comprises the following steps:
[0045] 1: Dissolve chitosan in distilled water, neutralize acrylic acid with sodium hydroxide or potassium hydroxide, select appropriate persulfate as initiator to initiate graft copolymerization, and prepare N,N'-methylenebisacrylamide as a cross-linking agent for subsequent cross-linking reaction;
[0046] 2: Under controlled temperature and time, the neutralized acrylic acid is mixed with the chitosan solution, an initiator is added to carry out graft copolymerization reaction, and on the basis of the graft copolymerization reaction, an appropriate amount of crosslinking agent is added to carry out crosslinking;

[0050] 2: After the reaction is completed, the product is washed and dried to remove unreacted monomers and other impurities to obtain pure temperature-sensitive diatomaceous earth gel.
[0051] A drawstring 6 is fixed to the end of the tampon body, and the drawstring 6 is formed by kneading two sections of yarn;
[0052] The drawstring 6 is provided so that when the tampon body needs to be replaced after being inserted into the vagina for a period of time, it can be easily taken out by pulling, thereby ensuring hygiene and improving the convenience of use.
[0053] The housing is a double-layer structure, which includes a conduit 3 and a receiving ring 12, and the conduit 3 and the receiving ring 12 are integrally formed, and the receiving ring 12 divides the interior of the conduit 3 into an inner chamber and an outer chamber, and the size of the inner chamber is adapted to the main body of the tampon, and a holding ring 11 is integrally formed at the bottom of the conduit 3;
[0054] In order to ensure the hygienic use of the tampon body, the accommodating ring 12 can be used to cover the tampon body before use to store and protect it.
[0055] The inner chamber and the outer chamber in the shell are slidably connected with a pusher, and the pusher includes a pusher shell 1 and an inner plate 9, the pusher shell 1 and the inner plate 9 are integrally formed, and the outer diameters of the pusher shell 1 and the inner plate 9 are respectively adapted to the outer chamber and the inner chamber;
[0056] When the tampon body needs to be used, the catheter 3 is inserted into the vagina, and then the pusher is pushed. The inner plate 9 pushes the bottom of the tampon body during the movement, so that the tampon body accommodated in the inner cavity gradually extends from the end of the catheter 3, and is inserted into the vagina to absorb menstrual blood.
[0057] A protective cover 5 is installed at one end of the conduit 3, and the surface of the protective cover 5 is arc-shaped;
[0058] In order to reduce the stimulation to the vagina during the insertion of the catheter 3, a protective cover 5 is provided to ensure that the catheter 3 is guided before being inserted into the vagina. At the same time, the arc-shaped protective cover 5 can alleviate the stimulation to the vagina. A gap is provided on the contact surface between the protective cover 5 and the catheter 3. When the tampon body is pushed, the impact force of the tampon body is used to unfold the protective cover 5, so that the tampon body can be smoothly inserted into the vagina.
[0059] When using this embodiment, first hold the holding ring 11 with your hand, then insert the shell into the vagina, after inserting to a certain depth, push the pushing member, and the tampon body moves along the inner chamber under the push of the pushing member, and the tampon body eventually breaks through the protective cover 5 and is inserted into the vagina, then pull the catheter 3 outward, and the tampon body is retained in the vagina to absorb menstrual blood. When the tampon body needs to be replaced after using it for a period of time, the pull rope 6 is pulled to take out the tampon body.
[0060] Embodiment 2:
[0061] A multi-layer tampon based on antibacterial absorbent material, such as Figures 1 to 6 As shown, in order to further improve the comfort during use, this embodiment makes the following supplements on the basis of embodiment 1: a moving ring 13 is slidably connected in the outer chamber of the shell, and a storage bag 14 is bonded to the outer wall of one side of the moving ring 13, a pin 7 used in conjunction with the storage bag 14 is integrally formed at one end of the inner plate 9, and a leakage hole 2 is opened on the circumferential outer wall of the catheter 3;
[0062] During the process of inserting the catheter 3 into the vagina, in order to prevent the surface of the catheter 3 from being too dry and causing damage to the vaginal wall during the insertion process, a storage bag 14 is arranged inside the outer chamber, so that when the inner plate 9 and the insertion needle 7 move along the outer chamber, the storage bag 14 is punctured by the insertion needle 7. After the storage bag 14 is punctured, the lubricating oil inside it eventually flows out through the leakage hole 2. The lubricating oil that flows out can lubricate the catheter 3, thereby reducing the discomfort after the catheter 3 is inserted into the vagina.
[0063] The outer wall of the conduit 3 is slidably connected with a scraper ring 10;
[0064] In order to ensure that the lubricating oil is more evenly distributed on the outer wall of the conduit 3, a scraper ring 10 is used to receive the lubricating oil flowing out of the leak hole 2 to prevent the lubricating oil from remaining on the hands. After the lubricating oil flows into the inner surface of the scraper ring 10, the scraper ring 10 slides along the outer wall of the conduit 3 and evenly applies the lubricating oil to the outer wall of the conduit 3.
[0065] The outer wall of the conduit 3 is provided with air holes 4;
[0066] When the storage capsule 14 is punctured by the needle 7, the pore 4 is first blocked by the hand. After the pore 4 is blocked, the air cannot be compressed, so when the needle 7 punctures the storage capsule 14, the moving ring 13 and the storage capsule 14 cannot slide relative to the outer chamber, resulting in the inability of the needle 7 to puncture the storage capsule 14. After the storage capsule 14 is punctured and the lubricating oil is applied to the outer wall of the catheter 3 by the scraper ring 10, the hand is removed from the pore 4, and the outer shell 1 and the inner plate 9 are pushed to slide along the outer chamber and the inner chamber respectively. In this process, the outer shell 1 is pushed to push the punctured storage capsule 14 together with the moving ring 13 along the outer chamber, and the tampon body is pushed out by the inner plate 9.
[0067] When this embodiment is used, in the initial stage, the moving ring 13 is set inside the outer chamber by static friction. First, the air hole 4 is blocked by hand. After the air hole 4 is blocked, the air cannot be compressed, so that when the needle 7 punctures the storage capsule 14, the moving ring 13 and the storage capsule 14 are prevented from sliding relative to the outer chamber. During the movement of the inner plate 9 and the needle 7, the storage capsule 14 is punctured by the needle 7. After the storage capsule 14 is punctured, the lubricating oil inside the storage capsule 14 eventually flows out through the leak hole 2. The lubricating oil that flows out can lubricate the catheter 3. The scraper ring 10 is used to scrape the lubricating oil that flows out from the leak hole 2. The lubricating oil is received, and after the lubricating oil flows into the inner surface of the scraper ring 10, the scraper ring 10 evenly smears the lubricating oil on the outer wall of the catheter 3 during the sliding process along the outer wall of the catheter 3. When the storage capsule 14 is punctured and the lubricating oil is smeared on the outer wall of the catheter 3 by the scraper ring 10, after the hand is removed from the air hole 4, the outer shell 1 and the inner plate 9 are pushed to slide along the outer chamber and the inner chamber respectively. In this process, the outer shell 1 is pushed to move the punctured storage capsule 14 together with the movable ring 13 along the outer chamber to its end, and the tampon body is pushed out by the inner plate 9, and the pushed out tampon body is retained inside the vagina.
[0068] The above is a preferred specific implementation manner of the present invention, and the protection scope of the present invention is not limited thereto. Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the prior art or public common sense, within the spirit and principle of the present invention, shall be covered by the protection scope of the present invention.
