At present, Chinese patent announcement number CN210301434U discloses a soft and skin-friendly diaper, including an absorbent body, the inner surface layer of the absorbent body is used to be close to the baby's skin, the outer surface layer of the absorbent body faces outward, an absorbent core is arranged inside the absorbent body, both long sides of the absorbent body are provided with three-dimensional guards, and the two short sides of the absorbent body are respectively provided with a front waist and a rear waist; the three-dimensional guards include an integrally formed three-dimensional side, a leg guard and a waist side guard, the three-dimensional side is upright and fixed to the two long sides of the absorbent body, the leg guard is an extension of the bottom of the three-dimensional side away from the absorbent body, and the waist side guard is arranged at both ends of the leg guard, and the waist side guard is respectively fixed with the front waist and the rear waist to form an extension of the waist of the diaper.

[0003] The utility model has good softness, is more comfortable and skin-friendly when in contact with the skin, and is not easy to wear the skin after long-term use. However, in actual use, since the polymer water-absorbing core is easy to clump and harden after absorbing water, the skin-friendly effect is poor, affecting the comfort during use. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes a skin-friendly and soft diaper to solve the problem that the absorbent core of the existing diapers is easy to clump and harden during use, thus affecting the comfort of use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A skin-friendly and soft diaper comprises a diaper body, wherein the diaper body comprises an absorbent portion and a front waistline and a rear waistline respectively fixedly connected to the front and rear ends of the absorbent portion; the absorbent portion comprises a skin-friendly surface layer, a guide layer, an absorbent layer and a liquid-impermeable bottom layer arranged in sequence from top to bottom.

[0007] The absorption layer includes an upper covering layer, a middle covering layer and a lower covering layer which are arranged in sequence from top to bottom; the upper covering layer is evenly provided with a plurality of recessed portions distributed along the length direction, and a receiving cavity is formed between adjacent recessed portions, and an absorption core is arranged in the receiving cavity; both sides of the middle covering layer extend downward and bend inward to cover under the lower covering layer, and an activated carbon layer is arranged between the middle covering layer and the lower covering layer.

[0008] Furthermore, a plurality of protrusions are evenly arranged on the skin-friendly surface layer, and the protrusions are hemispherical.

[0009] Furthermore, the recessed portion is fixedly connected to the middle coating layer.

[0010] Furthermore, the number of the recessed portions is 3-6.

[0011] Furthermore, the middle covering layer and the lower covering layer are both made of water-repellent and breathable non-woven fabrics.

[0012] Furthermore, the liquid-impermeable bottom layer includes a PE leak-proof bottom film and a soft non-woven fabric arranged at the lower end of the PE leak-proof bottom film.

[0013] Furthermore, the thickness of the absorbent core gradually decreases from the middle portion in the width direction of the diaper body to both sides.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] 1. A recessed portion is provided on the upper covering layer to form an accommodating cavity, which limits the expansion space of the absorbent core. When the absorbent core absorbs water, it will expand toward the space on both sides, which can effectively prevent the absorbent core from lumping, deforming, and bulging upward, thereby ensuring the wearing comfort. At the same time, the recessed portion can also help guide the liquid and improve the absorption efficiency of the liquid. An activated carbon layer is provided under the absorbent core to effectively absorb the odor of excrement and further enhance the comfort of the diaper.

[0016] 2. The raised design on the skin-friendly surface increases the water absorption area of ​​the skin-friendly surface, thereby accelerating the absorption of liquid; at the same time, the raised design reduces the contact area between the skin-friendly surface and the skin, ensuring that the skin surface can be ventilated and breathable, thereby reducing the occurrence of the "red buttocks" phenomenon and improving the wearing comfort of diapers.

[0017] 3. The thickness of the absorbent core is set to gradually decrease from the middle of the diaper body in the width direction to both sides, which is in line with the actual use situation that the amount of liquid absorbed by the two sides of the diaper is small, which can save materials and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 It is a cross-sectional structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] refer to Figure 1 and Figure 2This embodiment provides a skin-friendly and soft diaper, including a diaper body, the diaper body including an absorbent part 1 and a front waist circumference 2 and a rear waist circumference 3 respectively fixedly connected to the front and rear ends of the absorbent part 1; the absorbent part 1 includes a skin-friendly surface layer 4, a guide layer 5, an absorbent layer and a liquid-impermeable bottom layer 7 arranged in sequence from top to bottom. The skin-friendly surface layer 4, the guide layer 5, the absorbent layer and the liquid-impermeable bottom layer 7 are bonded together by an adhesive, the skin-friendly surface layer 4 is made of a soft and well-absorbent material, the guide layer 5 is made of wood pulp fibers, and the guide layer 5 can quickly and evenly disperse urine to the entire absorbent layer, effectively preventing the absorbent core from being locally saturated, thereby reducing the occurrence of lumps.

[0022] The absorption layer includes an upper coating layer 61, a middle coating layer 63 and a lower coating layer 65 arranged in sequence from top to bottom; the upper coating layer 61 is evenly provided with a plurality of depressions 611 distributed along the length direction, the depressions 611 are fixedly connected to the middle coating layer 63, and a receiving cavity 612 is formed between adjacent depressions 611, and an absorption core 62 is arranged in the receiving cavity 612; the two sides of the middle coating layer 63 extend downward and bend inward to be coated under the lower coating layer 65, and an activated carbon layer 64 is arranged between the middle coating layer 63 and the lower coating layer 65. The upper coating layer 61 can be made of dust-free paper or wet-strength paper; the absorption core 62 is composed of fluff pulp and high molecular water-absorbing resin. The setting of the recessed portion 611 can help guide the liquid and improve the absorption efficiency of the liquid; the setting of the accommodating cavity 612 limits the expansion space of the absorbent core 62. When the absorbent core 62 absorbs water, it will expand to the space on both sides, which can effectively prevent the absorbent core 62 from deforming and bulging upward, thereby ensuring the comfort of wearing. The setting of the activated carbon layer 64 can absorb the odor of excrement in the absorbent core 62 and further enhance the comfort of the diaper. The middle coating layer 63 and the lower coating layer 65 are both made of water-repellent and breathable non-woven fabrics, which can prevent the activated carbon layer 64 from getting wet and causing the adsorption effect of odor to deteriorate.

[0023] In this specific embodiment, a plurality of protrusions 41 are evenly arranged on the skin-friendly surface layer 4, and the protrusions 41 are hemispherical. The design of the protrusions 41 increases the water absorption area of ​​the skin-friendly surface layer 4, thereby accelerating the absorption speed of the liquid; at the same time, the protrusions 41 reduce the contact area between the skin-friendly surface layer 4 and the skin, ensuring that the skin surface can be ventilated and breathable, thereby reducing the occurrence of the "red buttocks" phenomenon and improving the wearing comfort.

[0024] In this specific embodiment, the number of the recessed portions 611 is 3 to 6. The number of the recessed portions 611 is limited in order to ensure the strength and absorption effect of the absorption layer.

[0025] In this specific embodiment, the liquid-impermeable bottom layer 7 includes a PE leakproof bottom film 71 and a soft non-woven fabric 72 disposed at the lower end of the PE leakproof bottom film 71. The PE leakproof bottom film 71 plays a waterproof and breathable role, and the soft non-woven fabric 72 has a soft and delicate touch, ensuring that the skin is not easily rubbed and turned red when in contact with the outer layer of the diaper.

[0026] In this specific embodiment, the thickness of each absorbent core 62 gradually decreases from the middle of the diaper body in the width direction to both sides. Since the liquid absorption amount on both sides is less, materials can be saved and production costs can be reduced.

[0027] The diaper of the utility model is skin-friendly, soft and has good water absorption, which solves the problem in the prior art that the core of the diaper may become clumping and hardening after absorbing water, thereby improving the wearing comfort of the diaper.

[0028] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
