[0044] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0045] In order to solve the above technical problems, as one aspect of the utility model, a liquid absorbing pad is provided, such as Figure 1 , Figure 5 , Figure 7 As shown, the absorbent pad 100 includes a core sheet 110, a waterproof layer 120 and a plurality of first reinforcement cores 130, wherein the first reinforcement cores 130 extend along the length direction of the core sheet 110, and the first reinforcement cores 130 are arranged in pairs and at intervals along the width direction of the core sheet 110 on the core sheet 110, and the waterproof layer 120 is coated on the surface of the core sheet 110 and the first reinforcement cores 130.

[0046] It can be understood that the absorbent pad 100 provided by the present invention is applied to absorbent articles such as pull-up pants, and is used to bend and cover the crotch of the wearer, and the core sheet 110 is used to absorb liquids such as urine flowing out of the wearer's lower body.

[0047] In the utility model, a first reinforcing core 130 is arranged on the core sheet 110 of the absorbent pad 100. The first reinforcing core 130 is arranged in the same direction as the core sheet 110 and is arranged on both sides of the core sheet 110 along the width direction of the core sheet 110. Therefore, when the liquid flowing out of the wearer suddenly increases and the core sheet 110 cannot absorb all the liquid independently, the first reinforcing cores 130 on both sides can absorb the liquid flowing to the side of the absorbent pad 100, thereby preventing the liquid from flowing out from the side of the absorbent article to form side leakage, thereby ensuring the wearer's body is clean.

[0048] As an optional implementation of the present invention, the first reinforcing core 130 includes a polymer water-absorbing layer and absorbent paper stacked and coated on both sides of the polymer water-absorbing layer.

[0049] As an optional implementation of the present utility model, the material of the polymer water-absorbing layer is a polymer water-absorbing resin.

[0050] As an optional implementation of the present utility model, the material of the polymer water-absorbing layer is sodium polyacrylate.

[0051] As an optional embodiment of the present invention, the first reinforcing core 130 includes a polymer mixed layer and fiber layers stacked and coated on both sides of the polymer mixed layer, and the polymer mixed layer includes a fiber skeleton and a polymer water-absorbing material distributed in the fiber skeleton.

[0052] As an optional implementation of the present utility model, the material of the polymer water-absorbing material is a polymer water-absorbing resin.

[0053] As an optional implementation of the present utility model, the material of the polymer water-absorbing layer is sodium polyacrylate.

[0054] As an optional implementation of the present utility model, Figure 6 As shown, one of the first reinforcing cores 130 on both sides of the core sheet 110 has a plurality of protrusions on the side facing the opposite first reinforcing core 130, and the other has a plurality of grooves on the side facing the opposite first reinforcing core 130, and the shapes of the plurality of protrusions correspond to and complement the shapes of the plurality of grooves.

[0055] In the embodiment of the utility model, the first reinforcing core 130 on both sides has a plurality of protrusions and a plurality of grooves on the sides facing the opposite sides, so that Fig. 9As shown, the inner edges of the first reinforcing core 130 on both sides are formed into a wavy structure, which can not only improve the elasticity of the first reinforcing core 130, so that it can better cope with various deformations such as folding and pressing, but also improve the aesthetics of the absorbent article. In addition, when manufacturing the first reinforcing core 130, a whole sheet can be cut into two first reinforcing cores 130 with complementary shapes, and the manufacturing process is simple and fast.

[0056] Optionally, the outer side of the first reinforcing core 130 may also be formed into a wavy structure, so that the first reinforcing core 130 extends in an “S” shape. In this case, both side sides of the first reinforcing core 130 are formed by cutting with the same type of cutter.

[0057] When wearing absorbent articles such as pull-up pants, back leakage may also occur. For example, when an infant or toddler wears pull-up pants and lies flat to sleep, the liquid produced in their lower body flows preferentially backwards under the action of gravity, and then easily flows out from the back waist, causing back leakage.

[0058] In order to solve the above technical problems, as a preferred implementation of the utility model, as Figure 1 , Figure 5 , Figure 7 As shown, the absorbent pad 100 further includes at least one second reinforcing core 140 , the position of the second reinforcing core 140 corresponds to the end of the core sheet 110 along its own extension direction, and the second reinforcing core 140 and the first reinforcing core 130 are located on the same side of the core sheet 110 .

[0059] In the embodiment of the utility model, the second reinforcing core 140 can reinforce the areas on both sides of the end of the core sheet 110 that are difficult to be covered by the first reinforcing core 130, thereby absorbing the liquid flowing to the wearer's waist, avoiding the problem of back leakage, and further ensuring the wearer's body cleanliness.

[0063] like Fig. 9 As shown, in the embodiment of the present invention, the ends of the second reinforcing core 140 are connected to the first reinforcing cores 130 on both sides, thereby surrounding to form a "U"-shaped water-absorbing structure (or a "mouth"-shaped water-absorbing structure when the second reinforcing core 140 is provided at both ends), further ensuring the water absorption effect of the absorbent pad 100.

[0064] In order to further ensure the water absorption effect of the liquid absorbent pad 100, as an optional embodiment of the present invention, Figure 8 As shown, the second reinforcing core 140 has enclosing parts 141 at both ends perpendicular to the extending direction of the core sheet 110 , and the enclosing parts 141 extend toward the other end of the core sheet 110 , thereby further preventing liquid from leaking from the junction of the first reinforcing core 130 and the second reinforcing core 140 .

[0065] As an optional implementation of the present utility model, Figure 1 , Figure 5 , Figure 7 As shown, the second reinforcing core 140 is disposed on the surface of the waterproof layer 120 facing away from the core sheet 110 .

[0066] As an optional implementation of the present utility model, Figure 1 , Figure 5 , Figure 7 As shown, the waterproof layer 120 is wound around the core sheet 110 in a direction perpendicular to the extension direction of the core sheet 110, and the opposite side edges of the waterproof layer 120 overlap on the surface of the core sheet 110 to form a folded edge portion, and the second reinforcement core 140 is arranged crosswise with the folded edge portion.
