Description

Technical Field

[0001] This utility model relates to the field of sanitary napkins, and in particular to an ultra-thin silk sanitary napkin. Background Technology

[0002] During menstruation, hormonal changes reduce the acidity of the vagina. Combined with the poor breathability of current sanitary napkins, the lack of air circulation in the vagina creates a breeding ground for bacteria, making it easy for infections such as Candida albicans to occur, leading to vaginal itching, especially when the weather is hot and humid. At the same time, the menstrual blood may also have an odor, seriously affecting women's normal life and work.

[0003] In existing technologies, such as the Chinese patent application CN209137104U entitled "A Pure Silk Hygiene Material," a pure silk facing layer, a bottom layer, and an absorbent layer disposed between the facing layer and the bottom layer are included. The absorbent layer includes a pure silk protective layer, within which are a pair of chip layers composed of Tencel fibers or wood fibers. Between the pair of chip layers is a uniformly distributed mesh layer made of silk fibers. Multiple absorbent polymers are evenly distributed on both surfaces of the mesh layer. Guide grooves are imprinted on the upper surfaces of the absorbent layer and the pure silk facing layer. The lower part of the pure silk protective layer is bonded to the bottom layer. This invention provides a non-irritating effect and highly uniform absorption.

[0004] In the current technology for using sanitary napkins, since the replacement standard for most sanitary napkins is determined based on the usage time, most sanitary napkins have low absorbency after replacement, resulting in low usage efficiency and waste.

[0005] Therefore, it is necessary to provide an ultra-thin silk sanitary napkin to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides an ultra-thin silk sanitary napkin, which solves the problem that most sanitary napkins have low absorbency after replacement because the standard replacement time for most sanitary napkins is determined by the usage time. This results in low usage efficiency and waste of sanitary napkins.

[0007] To solve the above-mentioned technical problems, this utility model provides an ultra-thin silk sanitary napkin, including a bottom layer, a positioning piece fixedly connected to the front of the bottom layer, a color-changing layer on the top of the bottom layer, a drainage strip fixedly sleeved inside the color-changing layer, a reference piece fixedly sleeved on the top of the color-changing layer, an absorbent core fixedly sleeved on the top of the color-changing layer, a drainage groove opened on the top of the absorbent core, shrinkage particles arranged inside the absorbent core, a positioning sleeve arranged on the top of the absorbent core, a cleaning core arranged inside the positioning sleeve, an air vent opened on the top of the positioning sleeve, an auxiliary mechanism arranged on the top of the positioning sleeve, and a fixing mechanism arranged on the top of the positioning piece.

[0008] Preferably, the color-changing layer is made of cobalt chloride, and the size of the color-changing layer is the same as that of the underlying layer.

[0009] Preferably, the shrinkage particles are made of silica aerogel material, and the number of shrinkage particles is several.

[0010] Preferably, the front of the guide groove is spiral-shaped and is located directly above the absorber core.

[0011] Preferably, the cleaning core is made of natural essential oil material, and the cleaning core is located in the center of the inner cavity of the positioning sleeve.

[0012] Preferably, the number of air vents is several, and the several air vents are evenly distributed on the top of the positioning sleeve.

[0013] Preferably, the auxiliary mechanism includes a silk layer, which is fixedly sleeved on the top of the positioning sleeve. The silk layer has relief particles inside, and the relief particles are made of nano-iron oxide material.

[0014] Preferably, the fixing mechanism includes an adhesive sheet, which is adhered to the top of the positioning sheet, and a dustproof sheet is adhered to the top of the adhesive sheet.

[0015] Compared with related technologies, the ultra-thin silk sanitary napkin provided by this utility model has the following beneficial effects:

[0016] This utility model provides an ultra-thin silk sanitary napkin. By setting a color-changing layer, when the sanitary napkin is in use, the drainage strip can absorb the blood inside the absorbent core and then conduct it to the inside of the color-changing layer. The color-changing layer changes color with the amount of blood entering. At this time, the user can estimate the amount of blood inside the color-changing layer by referring to the color of the reference sheet, thereby achieving real-time understanding of the absorption saturation inside the absorbent core. This allows the user to accurately determine whether the sanitary napkin needs to be changed, thus avoiding the problem of waste caused by frequent changes of sanitary napkins.

[0017] By incorporating an auxiliary mechanism, the sanitary napkin emits micron-level far-infrared rays when in use, allowing the far-infrared rays to irradiate the user for an extended period, thus achieving a far-infrared therapy effect. This relieves menstrual edema and enhances the functionality of the sanitary napkin. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of an ultra-thin silk sanitary napkin provided by this utility model; Figure 2 for Figure 1 The image shown is a front view of an ultra-thin silk sanitary napkin. Figure 3 for Figure 1 The image shows a cross-sectional view of a positioning sleeve in an ultra-thin silk sanitary napkin. Figure 4 for Figure 1The image shows a front view of the fixing mechanism in an ultra-thin silk sanitary napkin. The ultra-thin silk sanitary napkin includes a bottom layer 1, a positioning piece 2 fixedly connected to the front of the bottom layer 1, a color-changing layer 3 on the top of the bottom layer 1, a drainage strip 4 fixedly sleeved inside the color-changing layer 3, a reference piece 5 fixedly sleeved on the top of the color-changing layer 3, an absorbent core 6 fixedly sleeved on the top of the color-changing layer 3, a drainage groove 7 on the top of the absorbent core 6, shrinkage particles 8 inside the absorbent core 6, a positioning sleeve 9 on the top of the absorbent core 6, a cleaning core 10 inside the positioning sleeve 9, an air vent 11 on the top of the positioning sleeve 9, an auxiliary mechanism 12 on the top of the positioning sleeve 9, and a fixing mechanism 13 on the top of the positioning piece 2.

[0025] The color-changing layer 3 is made of cobalt chloride and is the same size as the bottom layer 1. By setting the color-changing layer 3, when the sanitary napkin is in use, the drainage strip 4 can absorb the blood inside the absorbent core 6 and conduct it to the inside of the color-changing layer 3, so that the color-changing layer 3 changes color with the amount of blood entering. At this time, the user can estimate the amount of blood inside the color-changing layer 3 by referring to the color of the reference piece 5, thereby achieving real-time understanding of the absorption saturation inside the absorbent core 6. This allows the user to accurately determine whether the sanitary napkin needs to be changed, thus avoiding the problem of waste caused by frequent changes of sanitary napkins.

[0026] The shrinkable particles 8 are made of silica aerogel material, and there are several shrinkable particles 8. By setting the shrinkable particles 8, when the absorbent core 6 absorbs liquid, the shrinkable particles 8 can slowly shrink, that is, drive the absorbent core 6 to shrink, thereby reducing the expansion volume of the absorbent core 6 when absorbing liquid, and thus avoiding the problem of expansion when the sanitary napkin is used.

[0027] The front of the guide channel 7 is spiral-shaped and is located directly above the absorber core 6. By setting the guide channel 7, when the absorber core 6 absorbs the liquid, the guide channel 7 can guide the liquid in the middle of the absorber core 6 and then transport it to the edge of the absorber core 6, thereby achieving a uniform and stable absorption effect of the liquid and avoiding the problem of seepage when the liquid stays in the same position.

[0028] The cleaning core 10 is made of natural essential oil material and is located in the center of the inner cavity of the positioning sleeve 9. By setting the cleaning core 10, when the sanitary napkin is used, the cleaning core 10 is warmed by the user's body temperature and the gas evaporates, so that the gas of the cleaning core 10 can cover the odor inside the sanitary napkin, thereby avoiding the problem of odor when the sanitary napkin is used and improving the freshness effect when the sanitary napkin is used.

[0029] There are several air vents 11, which are evenly distributed on the top of the positioning sleeve 9. By setting the air vents 11, when the sanitary napkin is in use, the airflow inside the sanitary napkin can circulate through the air vents 11, thereby improving the breathability of the sanitary napkin when in use, that is, improving the comfort of the sanitary napkin when used for a long time.

[0030] The auxiliary mechanism 12 includes a silk layer 121, which is fixedly sleeved on the top of the positioning sleeve 9. The silk layer 121 has relief particles 122 inside, which are made of nano-iron oxide material. By setting the auxiliary mechanism 12, when the sanitary napkin is used, the relief particles 122 can emit micron-level far-infrared rays, so that the far-infrared rays can irradiate the user for a long time, thereby achieving the far-infrared therapy effect, that is, achieving the effect of relieving menstrual edema.

[0031] The fixing mechanism 13 includes an adhesive sheet 131, which is attached to the top of the positioning sheet 2. A dustproof sheet 132 is attached to the top of the adhesive sheet 131. By setting the fixing mechanism 13, when using the sanitary napkin, the dustproof sheet 132 can be peeled off, allowing the adhesive sheet 131 to drive the bottom layer 1 to adhere to the user's skin surface, thereby driving the sanitary napkin to adhere and fix to the skin surface, thus bringing convenience to the fixed use of the sanitary napkin.

[0032] The working principle of the ultra-thin silk sanitary napkin provided by this utility model is as follows:

[0033] Step 1: When using a sanitary napkin, the drainage strip 4 absorbs the blood inside the absorbent core 6 and conducts it to the color-changing layer 3. The color-changing layer 3 changes color with the amount of blood entering, allowing the user to estimate the amount of blood inside the color-changing layer 3 by referring to the color of the reference sheet 5. This allows the user to understand the absorption saturation inside the absorbent core 6 in real time, enabling them to accurately determine whether the sanitary napkin needs to be changed, thus avoiding the waste caused by frequent changes. When the absorbent core 6 absorbs menstrual fluid, the shrinking particles 8 slowly shrink, causing the absorbent core 6 to shrink, thereby reducing the expansion volume of the absorbent core 6 when absorbing liquid and preventing the sanitary napkin from swelling during use. When the absorbent core 6 absorbs menstrual fluid, the guide groove 7 guides the menstrual fluid in the middle of the absorbent core 6 to the edge of the absorbent core 6, thus achieving a uniform and stable absorption effect and preventing the problem of leakage when menstrual fluid stays in the same place.

[0034] Step 2: When the sanitary napkin is used, the cleaning core 10 is warmed by the user's body temperature, causing gas evaporation. This gas from the cleaning core 10 masks any odor inside the sanitary napkin, preventing unpleasant smells and improving its freshness. During use, the airflow inside the sanitary napkin circulates through the ventilation holes 11, further enhancing breathability and comfort during prolonged use. The relief particles 122 emit micron-level far-infrared rays, providing prolonged exposure and achieving a far-infrared therapy effect, thus relieving menstrual swelling. Finally, removing the dust cover 132 allows the adhesive sheet 131 to adhere the bottom layer 1 to the user's skin, securing the sanitary napkin to the skin and facilitating its secure use.

[0035] Compared with related technologies, the ultra-thin silk sanitary napkin provided by this utility model has the following beneficial effects:

[0036] By incorporating a color-changing layer 3, when a sanitary napkin is in use, the drainage strip 4 absorbs the blood inside the absorbent core 6 and conducts it to the color-changing layer 3. This causes the color-changing layer 3 to change color with the amount of blood entering it. At this time, the user can estimate the amount of blood inside the color-changing layer 3 by referring to the color of the reference sheet 5, thereby achieving real-time understanding of the absorption saturation inside the absorbent core 6. This allows the user to accurately determine whether the sanitary napkin needs to be changed, thus avoiding the waste caused by frequent changes of sanitary napkins.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content 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.
