[0008] Furthermore, the collecting grooves are in the shape of long strips, and the length direction of the collecting grooves is parallel to the length direction of the main body.

[0009] Furthermore, the ratio of the length of the collecting tank to the length of the main body is 1:5-1:7.

[0010] Furthermore, guardrails are respectively arranged on both sides of the main body, and the guardrails are made of skin-friendly fabric.

[0011] Furthermore, the fixing structure includes a first extension part and a second extension part, the first extension part and the second extension part are respectively arranged at two ends of the main body, both sides of the first extension part are respectively provided with soft hairs, and both sides of the second extension part are respectively provided with bristles, and the soft hairs and the bristles cooperate to form Velcro.

[0012] Furthermore, the first extension part and the second extension part are respectively provided with a first elastic band and a second elastic band, soft bristles are provided at both ends of the first elastic band, and bristles are provided at both ends of the second elastic band.

[0013] Furthermore, there are multiple collecting grooves, which are distributed on the core body, and the collecting grooves are not connected to each other.

DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0023] like Figures 1 to 3As shown, the utility model provides a diaper with a guide structure, including a main body 1 and a fixed structure 2 arranged on the main body 1, the main body 1 includes a bottom film 3, a core 4 and a surface layer 5, the core 4 is arranged between the bottom film 3 and the surface layer 5, and also includes a collecting groove 6, the core 4 includes a guide layer 13 and an absorption core layer 14, the guide layer 13 is arranged between the surface layer 5 and the absorption core layer 14, the absorption core layer 14 is arranged between the guide layer 13 and the bottom film 3, and the collecting groove 6 runs through the guide layer 13 and the absorption core layer 14.

[0024] Specifically, the utility model provides a through-guide groove in the core body 4 so that when urine passes through the surface layer 5 and contacts the core body 4, the urine can not only penetrate into the absorption core layer 14 through the guide layer 13, but also directly contact the absorption core layer 14 through the collecting groove 6. Since this part of urine directly contacts the absorption core layer 14, the absorption core layer 14 can absorb it quickly, thereby greatly improving the absorption efficiency of the absorption core layer 14, avoiding the urine from staying in the surface layer 5 and the guide layer 13 for a long time, thereby reducing the baby's experience.

[0025] In this embodiment, the collecting grooves 6 are in the shape of long strips, and the length direction of the collecting grooves 6 is parallel to the length direction of the main body 1, so that the shape of the collecting grooves 6 is adapted to the shape of the main body 1, thereby ensuring the absorption effect.

[0026] In this embodiment, the ratio of the length of the collecting groove 6 to the length of the main body 1 is 1:5-1:7. Under the above length, the collecting groove 6 not only ensures the absorption effect, but also does not cause the guide layer 13 and the absorption core layer 14 to be easily broken due to the excessive length of the collecting groove 6, thereby ensuring the stability and strength of the utility model.

[0027] In this embodiment, guards 15 are respectively arranged on both sides of the main body 1, and the guards 15 are made of skin-friendly fabric. The guards 15 are mainly adapted to the positions on both sides of the human body's crotch, so that the baby will not leak due to large movements.

[0028] In this embodiment, the fixing structure 2 includes a first extension portion 7 and a second extension portion 8. The first extension portion 7 and the second extension portion 8 are respectively arranged at two ends of the main body 1. Soft bristles 9 are respectively provided on both sides of the first extension portion 7, and bristles 10 are respectively provided on both sides of the second extension portion 8. The soft bristles 9 and the bristles 10 cooperate to form Velcro.

[0029] That is, the utility model uses Velcro to fix the two ends, so that the utility model can be quickly worn and can also ensure that it will not fall off during the baby's movements.

[0030] Specifically, the first extension part 7 and the second extension part 8 are respectively provided with a first elastic band 11 and a second elastic band 12, the soft hair 9 is provided at both ends of the first elastic band 11, and the bristles 10 are provided at both ends of the second elastic band 12. By providing the first elastic band 11 and the second elastic band 12, the effect of adhering the bristles 10 and the soft hair 9 to adapt to the waist circumference of the baby is achieved.

[0031] As another embodiment of the present invention, there are multiple collecting grooves 6 , and the multiple collecting grooves 6 are distributed on the core body 4 , and the collecting grooves 6 are not connected to each other.

[0032] In the application of this other embodiment, the ratio of the total length of the plurality of collecting grooves 6 to the length of the main body 1 is 1:5-1:7.

[0033] by Figure 4 For example, a plurality of collecting grooves 6 can be distributed at different positions of the main body 1 , so that the absorption range is larger. No matter from which direction the urine enters the main body 1 , it can be quickly absorbed through the collecting grooves 6 .

[0034] Of course, the most suitable ratio of the total length of the collecting tank 6 to the length of the main body 1 is still between 1:5 and 1:7.

[0035] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form.
