[0019] In order to make the above objects, features and advantages of the present invention more clearly comprehensible, the present invention will be described in more detail below in combination with drawings and specific embodiments. It should be noted that, unless there is a contradiction, the features in the embodiments and the embodiments of the present application can be combined with each other.

[0020] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention; however, the present invention may be embodied in other forms different from those described herein, and therefore the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] Hereinafter, several embodiments of the leak-prevention urine pad of the present invention will be described with reference to Figs.

[0022] As shown in Fig. 1 to Fig. 23, an embodiment of the present invention provides a leak-proof urine pad including a water-impermeable layer 1, a water-absorbent layer 2 provided on the upper surface of the water-impermeable layer 1, and an edge seal assembly fixedly connected to the water-impermeable layer and / or the water-absorbent layer. The edge seal assembly can be fixedly connected to an edge of the water-impermeable layer 1 and / or an edge of the water-absorbent layer 2, and the edge seal assembly can be fixedly connected to a position other than the edge of the water-impermeable layer 1 or the edge of the water-absorbent layer 2. When the edge seal assembly is fixedly connected to a position other than the edge of the water-impermeable layer 1 or the water-absorbent layer 2, the space surrounded by the side of the edge seal assembly close to the center of the water-impermeable layer 1 needs to be sufficient for pets to urinate, so as to avoid urine from directly spilling outside the edge seal assembly, and the distance between the side of the edge seal assembly far from the center of the water-impermeable layer 1 and the corresponding edge of the water-impermeable layer 1 is 0 to 10 cm, and the specific dimensions are determined according to the actual usage situation.

[0023] The water impermeable layer 1 is made of a PE (polyethylene) casting film, so that the urine can be completely absorbed in the water absorbent layer 2, and the PE casting film can achieve a leakage prevention effect. The water absorbent layer 2 is provided on the surface of the water impermeable layer 1, so that the water absorbent layer 2 includes a nonwoven PP (polypropylene), a sanitary paper layer, a wood pulp layer, and a sanitary paper layer in this order. When urine enters the water absorbent layer 2, the nonwoven PP has no water absorption ability, but the urine can pass through the nonwoven PP and enter the sanitary paper layer, the wood pulp layer, and the sanitary paper layer in this order. The two sanitary paper layers and the wood pulp layer can quickly absorb the urine, and the nonwoven PP layer can achieve a protective effect for the sanitary paper layer, and can prevent the sanitary paper layer from being rubbed and damaged. The edge seal assembly is provided on the edge of the water impermeable layer 1 or the edge of the water absorbent layer 2, so that the edge seal assembly can block the urine flowing to the edge of the water absorbent layer 2, and can prevent the urine from spilling on the ground, and can reduce the impact of the urine on environmental hygiene. EXAMPLES

[0024] 1 to 4, in one embodiment of the present invention, the edge seal assembly includes a first edge seal 3, the first edge seal 3 at one end remote from the center of the water absorbent layer 2 being fixedly connected to a pair of sides of the water impermeable layer 1 and a pair of sides of the water absorbent layer 2, and a second edge seal 4, the second edge seal 4 provided on another pair of sides of the water impermeable layer 1, both ends of the second edge seal 4 being fixedly connected to the two first edge seals 3, respectively, and the second edge seal 4 at one end remote from the center of the water absorbent layer 2 being fixedly connected to the other pair of sides of the water impermeable layer 1 and the other pair of sides of the water absorbent layer 2. In the horizontal direction, the area of ​​the water impermeable layer 1 is larger than the area of ​​the water absorbent layer 2, and the water absorbent layer 2 is fixedly connected to a central portion of an upper surface of the water impermeable layer 1. The length of the first edge seal 3 is greater than the length of the corresponding side of the water impermeable layer 1 , and the length of the second edge seal 4 is greater than the length of the corresponding side of the water impermeable layer 1 .

[0025] The two first edge seals 3 each cover a pair of sides of the water-shielding layer 1 and the water-absorbing layer 2, and the side of the first edge seal 3 away from the center of the water-shielding layer 1 is fixedly connected to the edges of the water-shielding layer 1 and the water-absorbing layer 2, so that the side of the first edge seal 3 closer to the center of the water-shielding layer 1 is not connected to the water-shielding layer 1 and the water-absorbing layer 2. The second edge seal 4 covers the other pair of sides of the water-shielding layer 1, and both ends of the second edge seal 4 are fixedly connected to the two first edge seals 3, respectively, and the side of the second edge seal 4 away from the center of the water-shielding layer 1 is fixedly connected to the edges of the water-shielding layer 1 and the water-absorbing layer 2, and the side of the second edge seal 4 closer to the center of the water-shielding layer 1 is not connected to the water-shielding layer 1 and the water-absorbing layer 2. Because the length of the first edge seal 3 is greater than the length of the corresponding side of the water impermeable layer 1, the side of the first edge seal 3 closer to the center of the water impermeable layer 1 rises upward, creating a gap between the side of the first edge seal 3 closer to the center of the water impermeable layer 1 and the water impermeable layer 1. Because the length of the second edge seal 4 is greater than the length of the corresponding side of the water impermeable layer 1, the side of the second edge seal 4 closer to the center of the water impermeable layer 1 rises upward, creating a gap between the side of the second edge seal 4 closer to the center of the water impermeable layer 1 and the water impermeable layer 1, and if urine flows too far around the water absorbent layer 2, the urine can flow into the gap. Since the side of the first edge seal 3 far from the center of the water-proof layer 1 is fixedly connected to the water-proof layer 1, and the side of the second edge seal 4 far from the center of the water-proof layer 1 is fixedly connected to the water-proof layer 1, the first edge seal 3 and the second edge seal 4 block urine and prevent urine from overflowing onto the ground from the first edge seal 3 and the second edge seal 4. Furthermore, the first edge seal 3 and the second edge seal 4 block urine in all directions, preventing urine from overflowing onto the ground from the urine pad, and reducing the impact of urine on environmental hygiene.

[0026] Both the first edge seal 3 and the second edge seal 4 are made of nonwoven fabric, and by treating the nonwoven fabric with a water repellent agent, the nonwoven fabric has a water repellent function and achieves an even greater blocking effect against urine.

[0027] Further, the distance between the first edge seal 3 and the second edge seal 4 and the corresponding side edge edge of the water-impermeable layer 1 is 0 to 10 cm. For example, the distance between the first edge seal 3 on the left side and the left side edge of the water-impermeable layer 1 is 5 cm, the distance between the first edge seal 3 on the right side and the right side edge of the water-impermeable layer 1 is 5 cm, the distance between the second edge seal 4 at the front end and the edge of the front side edge of the water-impermeable layer 1 is 5 cm, and the distance between the second edge seal 4 at the rear end and the edge of the rear side edge of the water-impermeable layer 1 is 5 cm. The principle of blocking urine by the first edge seal 3 and the second edge seal 4 at this time is the same as the above principle, and will not be described here.

[0028] As shown in FIG. 5, in one embodiment of the present invention, an elastic member 5 is fixedly connected to the first edge seal 3 and the second edge seal 4 on the side closer to the center of the water impermeable layer 1 .

[0029] The elastic member 5 is fixedly connected to the side of the first edge seal 3 and the second edge seal 4 closer to the center of the water-proof layer 1, so that in the relaxed state of the elastic member 5, the length of the elastic member 5 is smaller than the length of the corresponding first edge seal 3 and second edge seal 4. After the elastic member 5 is fixedly connected to the first edge seal 3 and the second edge seal 4, the elastic member 5 is in an extended state, and further, the elastic member 5 has a tensile force on the first edge seal 3 and the second edge seal 4, and the first edge seal 3 and the second edge seal 4 can be pulled by the elastic member 5, ensuring that the first edge seal 3 and the second edge seal 4 can rise upward, so that urine can smoothly enter between the first edge seal 3 and the water absorbent layer 2, and between the second edge seal 4 and the water absorbent layer 2, and further reducing the external leakage of urine. EXAMPLES

[0030] 6 to 12, in one embodiment of the present invention, the edge seal assembly includes a first edge seal 3, the first edge seal 3 at one end remote from the center of the water absorbent layer 2 being fixedly connected to a pair of sides of the water impermeable layer 1 and a pair of sides of the water absorbent layer 2, and a second edge seal 4, the second edge seal 4 provided on another pair of sides of the water impermeable layer 1, both ends of the second edge seal 4 being fixedly connected to the two first edge seals 3, respectively, and the second edge seal 4 at one end remote from the center of the water absorbent layer 2 being fixedly connected to the other pair of sides of the water impermeable layer 1 and the other pair of sides of the water absorbent layer 2. In the horizontal direction, the area of ​​the water impermeable layer 1 is larger than the area of ​​the water absorbent layer 2, and the water absorbent layer 2 is fixedly connected to a central portion of an upper surface of the water impermeable layer 1.

[0031] The two first edge seals 3 cover a pair of sides of the water impermeable layer 1 and the water absorbent layer 2, respectively, and the sides of the first edge seals 3 away from the center of the water impermeable layer 1 are fixedly connected to the edges of the water impermeable layer 1 and the water absorbent layer 2, so that the side of the first edge seal 3 closer to the center of the water impermeable layer 1 is not connected to the water impermeable layer 1 and the water absorbent layer 2. The second edge seal 4 covers the other pair of sides of the water impermeable layer 1, and both ends of the second edge seal 4 are fixedly connected to the two first edge seals 3, respectively, and the sides of the second edge seal 4 away from the center of the water impermeable layer 1 are not fixedly connected to the edges of the water impermeable layer 1 and the water absorbent layer 2. The side of the second edge seal 4 closer to the center of the water impermeable layer 1 is not connected to the water impermeable layer 1 and the water absorbent layer 2. Since the length of the first edge seal 3 is equal to the length of the side of the corresponding water-impermeable layer 1, and the length of the second edge seal 4 is equal to the length of the side of the corresponding water-impermeable layer 1, the sides of the first edge seal 3 and the second edge seal 4 close to the center of the water-impermeable layer 1 are in contact with the water-absorbent layer 2. The first edge seal 3, the second edge seal 4 and the water-absorbent layer 2 are all made of soft materials, and there is a certain gap between the water-absorbent layer 2 and the first edge seal 3 and the second edge seal 4, so that urine can flow into the gap, thereby achieving the effect of reducing urine flowing out from the edge of the water-impermeable layer 1. Furthermore, since the first edge seal 3 and the second edge seal 4 have a certain thickness, the height of the sides of the first edge seal 3 and the second edge seal 4 close to the center of the water-impermeable layer 1 is higher than the water-absorbent layer 2. Furthermore, when urine flows into the first edge seal 3 and the second edge seal 4, the first edge seal 3 and the second edge seal 4 can block the urine and prevent urine leakage. The first edge seal 3 and the second edge seal 4 block urine in all directions, preventing urine from spilling onto the ground from the urine pad, and reducing the impact of urine on environmental hygiene.

[0032] As shown in FIGS. 9 to 12, in one embodiment of the present invention, the second edge seal 4 is integrally formed with the water impermeable layer 1 .

[0033] By integrally molding the second edge seal 4 and the water impermeable layer 1, the number of processing steps for the second edge seal 4 and the water impermeable layer 1 can be reduced, and the processing difficulty can be reduced.

[0034] Furthermore, both the first edge seal 3 and the second edge seal 4 are manufactured using a PE casting membrane, and the second edge seal 4 and the water-proof layer 1 are integrally molded, which reduces the types of materials used and reduces the processing steps.

[0035] Furthermore, the distance between the first edge seal 3 and the corresponding side of the water-impermeable layer 1 is 0 to 10 cm. For example, when the left first edge seal 3 is fixedly connected to a position 5 cm away from the edge of the left side of the water-impermeable layer 1 and the right first edge seal is fixedly connected to a position 5 cm away from the edge of the right side of the water-impermeable layer 1, the principle of urine blocking by the first edge seals 3 on both the left and right sides is the same as the above principle, and a description thereof will be omitted here. EXAMPLES

[0036] As shown in Fig. 13 to Fig. 16, in one embodiment of the present invention, the edge seal assembly includes a first edge seal 3, the first edge seal 3 at one end remote from the center of the water absorbent layer 2 is fixedly connected to a pair of sides of the water absorbent layer 2, and a second edge seal 4, the second edge seal 4 is provided on the other pair of sides of the water absorbent layer 2, both ends of the second edge seal 4 are fixedly connected to the two first edge seals 3, and the second edge seal 4 at one end remote from the center of the water absorbent layer 2 is fixedly connected to the other pair of sides of the water absorbent layer 2. The length of the first edge seal 3 is greater than the length of the corresponding side of the water absorbent layer 2, and the length of the second edge seal 4 is greater than the length of the corresponding side of the water absorbent layer 2. In the horizontal direction, the area of ​​the water shielding layer 1 is equal to the area of ​​the water absorbent layer 2.

[0037] The two first edge seals 3 cover a pair of side edges of the water absorbent layer 2, respectively, and the side of the first edge seal 3 away from the center of the water shielding layer 1 is fixedly connected to the edge of the water absorbent layer 2, so that the side of the first edge seal 3 close to the center of the water shielding layer 1 is not connected to the water absorbent layer 2, and the second edge seal 4 covers the other pair of side edges of the water absorbent layer 2, and both ends of the second edge seal 4 are fixedly connected to the two first edge seals 3, respectively, and the side of the second edge seal 4 away from the center of the water shielding layer 1 is fixedly connected to the edge of the water absorbent layer 2, and the side of the second edge seal 4 close to the center of the water absorbent layer 2 is not connected to the water absorbent layer 2. Since the length of the first edge seal 3 is greater than the length of the corresponding side edge of the water absorbent layer 2, the side of the first edge seal 3 close to the center of the water absorbent layer 2 rises upward, so that there is a gap between the side of the first edge seal 3 close to the center of the water absorbent layer 2 and the water absorbent layer 2. Since the length of the second edge seal 4 is greater than the length of the corresponding side of the absorbent layer 2, the side of the second edge seal 4 close to the center of the absorbent layer 2 is raised upward, so that there is a gap between the side of the second edge seal 4 close to the center of the absorbent layer 2 and the absorbent layer 2, and when urine flows too much around the absorbent layer 2, the urine can flow into the gap. Since the side of the first edge seal 3 far from the center of the absorbent layer 2 is fixedly connected to the absorbent layer 2 and the side of the second edge seal 4 far from the center of the absorbent layer 2 is fixedly connected to the absorbent layer 2, the first edge seal 3 and the second edge seal 4 can block urine and prevent urine from spilling onto the ground from the first edge seal 3 and the second edge seal 4, and further, the first edge seal 3 and the second edge seal 4 can block urine in all directions, prevent urine from spilling onto the ground from the urine pad, and reduce the impact of urine on environmental hygiene.

[0038] The material of the first edge seal 3 and the second edge seal 4 is the same as the material of the water absorbent layer 2, and the first edge seal 3 and the second edge seal 4 are capable of re-absorb- ing urine during blocking.

[0039] Further, the distance between the first edge seal 3 and the second edge seal 4 and the corresponding side edge edge of the water-impermeable layer 1 is 0 to 10 cm. For example, the distance between the first edge seal 3 on the left side and the left side edge of the water-impermeable layer 1 is 5 cm, the distance between the first edge seal 3 on the right side and the right side edge of the water-impermeable layer 1 is 5 cm, the distance between the second edge seal 4 at the front end and the edge of the front side edge of the water-impermeable layer 1 is 5 cm, and the distance between the second edge seal 4 at the rear end and the edge of the rear side edge of the water-impermeable layer 1 is 5 cm. The principle of blocking urine by the first edge seal 3 and the second edge seal 4 at this time is the same as the above principle, and will not be described here.

[0040] As shown in FIG. 16, in one embodiment of the present invention, an elastic member 5 is fixedly connected to the first edge seal 3 and the second edge seal 4 on the side closer to the center of the water impermeable layer 1 .

[0041] The elastic member 5 is fixedly connected to the side of the first edge seal 3 and the second edge seal 4 close to the center of the water absorbent layer 2, so that in the relaxed state of the elastic member 5, the length of the elastic member 5 is smaller than the length of the corresponding first edge seal 3 and second edge seal 4. After the elastic member 5 is fixedly connected to the first edge seal 3 and the second edge seal 4, the elastic member 5 is in an elongated state, and further, the elastic member 5 has a tensile force on the first edge seal 3 and the second edge seal 4, and the first edge seal 3 and the second edge seal 4 can be pulled by the elastic member 5, ensuring that the first edge seal 3 and the second edge seal 4 can be raised upward, so that urine can smoothly enter between the first edge seal 3 and the water absorbent layer 2, and between the second edge seal 4 and the water absorbent layer 2, and the external leakage of urine can be further reduced. EXAMPLES

[0042] As shown in Fig. 17 to Fig. 23, in one embodiment of the present invention, the edge seal assembly includes a first edge seal 3, the first edge seal 3 at one end remote from the center of the absorbent layer 2 is fixedly connected to a pair of sides of the absorbent layer 2, and a second edge seal 4, the second edge seal 4 is provided on the other pair of sides of the absorbent layer 2, both ends of the second edge seal 4 are fixedly connected to the two first edge seals 3, and the second edge seal 4 at one end remote from the center of the absorbent layer 2 is fixedly connected to the other pair of sides of the absorbent layer 2. The length of the first edge seal 3 is equal to the length of the corresponding side of the absorbent layer 2, and the length of the second edge seal 4 is equal to the length of the corresponding side of the absorbent layer 2. In the horizontal direction, the area of ​​the water shielding layer 1 is equal to the area of ​​the absorbent layer 2.

[0043] The two first edge seals 3 each cover a pair of sides of the water absorbent layer 2, and the side of the first edge seal 3 away from the center of the water absorbent layer 2 is fixedly connected to the edge of the water absorbent layer 2, so that the side of the first edge seal 3 closer to the center of the water absorbent layer 2 is not connected to the water absorbent layer 2, and the second edge seal 4 covers the other pair of sides of the water absorbent layer 2, and both ends of the second edge seal 4 are fixedly connected to the two first edge seals 3, respectively, and the side of the second edge seal 4 away from the center of the water absorbent layer 2 is not fixedly connected to the edge of the water absorbent layer 2. The side of the second edge seal 4 closer to the center of the water absorbent layer 2 is not connected to the water shielding layer 1 and the water absorbent layer 2. The length of the first edge seal 3 is equal to the length of the side of the corresponding absorbent layer 2, and the length of the second edge seal 4 is equal to the length of the side of the corresponding absorbent layer 2, so that the sides of the first edge seal 3 and the second edge seal 4 close to the center of the absorbent layer 2 are in contact with the absorbent layer 2; the first edge seal 3, the second edge seal 4 and the absorbent layer 2 are all made of soft materials, and there is a certain gap between the absorbent layer 2 and the first edge seal 3 and the second edge seal 4, so that urine can flow into the gap, thereby achieving the effect of reducing urine flowing out from the edge of the absorbent layer 2; and the first edge seal 3 and the second edge seal 4 have a certain thickness, so that the height of the sides of the first edge seal 3 and the second edge seal 4 close to the center of the absorbent layer 2 is higher than the absorbent layer 2, so that when urine flows into the first edge seal 3 and the second edge seal 4, the first edge seal 3 and the second edge seal 4 can block the urine and avoid urine leakage. The first edge seal 3 and the second edge seal 4 block urine in all directions, preventing urine from spilling onto the ground from the urine pad, and reducing the impact of urine on environmental hygiene.

[0044] As shown in FIGS. 21 to 23, in one embodiment of the present invention, the second edge seal 4 is integrally formed with the water absorbent layer 2 .

[0045] By integrally molding the second edge seal 4 and the water absorbent layer 2, the number of processing steps for the second edge seal 4 and the water absorbent layer 2 can be reduced, and the processing difficulty can be reduced.

[0046] Furthermore, the materials of the first edge seal 3 and the second edge seal 4 are both the same as the material of the water absorbent layer 2, and the second edge seal 4 and the water shielding layer 1 are integrally molded, thereby reducing the types of materials used and the number of processing steps.

[0047] Furthermore, the distance between the first edge seal 3 and the corresponding side of the water-impermeable layer 1 is 0 to 10 cm. For example, when the left first edge seal 3 is fixedly connected to a position 5 cm away from the edge of the left side of the water-impermeable layer 1 and the right first edge seal is fixedly connected to a position 5 cm away from the edge of the right side of the water-impermeable layer 1, the principle of urine blocking by the first edge seals 3 on both the left and right sides is the same as the above principle, and a description thereof will be omitted here.

[0048] The present invention has the following advantages:

[0049] By installing the edge seal assembly 0 to 10 cm away from the edge of the water-impermeable layer 1 or the water-absorbent layer 2, the edge seal assembly can block urine flowing over the edge of the water-absorbent layer 2, prevent urine from spilling onto the ground, and reduce the impact of urine on environmental hygiene.
