Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application claims priority to Chinese Patent Application No. 202522580503.7, filed on Dec. 2, 2025, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present application relates to the technical field of maternal and baby products, particularly to a absorbent garment. BACKGROUND In recent years, absorbent garments have been increasingly accepted as an emerging product. Typically used by women during menstruation or by individuals with incontinence, absorbent garments can absorb bodily fluids and prevent leakage. Unlike disposable absorbent products such as sanitary napkins and diapers, absorbent garments are reusable and washable clothing. An absorbent garment mainly consists of a pants body and an absorbent assembly. The method of securing and connecting these two components directly affects the user's wearing experience. As disclosed in U.S. patent application Ser. No. 16/567,212, one existing method involves bonding the absorbent assembly to the pants body using adhesive. While this approach offers advantages in preventing leakage and side leakage for a certain period, as bodily fluids can be completely contained within the absorbent assembly, it performs poorly in terms of breathability. Additionally, the garment does not dry easily after washing. Moreover, the adhesive tends to degrade under repeated washing or conditions such as machine drying, resulting in a relatively short service life. As disclosed in U.S. patent application Ser. No. 17/475,690, another existing method involves using a bound-edge stitching technique. Specifically, both sides of the crotch region of the pants body wrap around the absorbent assembly to form elastic bound edges, which are then stitched to the absorbent assembly. In this method, the stitching is directly exposed and faces the wearer's crotch. Furthermore, due to the elasticity of the bound edges, the pressure generated by the elasticity presses the stitching tightly against the skin of the wearer's crotch, leading to reduced wearing comfort. Therefore, there is a need to provide an absorbent garment to address the above technical issues. SUMMARY In view of the deficiencies in the prior art, the present application provides an absorbent garment, which can solve the problems of poor wearing comfort and breathability in existing absorbent garments. In order to solve the above technical problem, one embodiment of this application proposes an absorbent garment comprises: a pants body having an upper edge for surrounding a wearer's waist during wearing, two leg openings configured to allow the wearer's legs to pass through, and a crotch region located between the two leg openings; a base layer combined with the pants body at least on both sides of the crotch region, wherein the base layer and the pants body enclose a receiving space, and the base layer is configured to face toward the wearer's crotch during wearing; the pants body has a first edge on one side of the crotch region, the base layer has a second edge corresponding to the first edge, and the first edge and the second edge extend into the receiving space and are sewn together by stitching within the receiving space; and an absorption layer located within the receiving space and combined with the base layer or the pants body. In one embodiment, the first edge of the pants body is folded and extends into the receiving space. In one embodiment, the stitching is concealed within the receiving space. In one embodiment, the base layer comprises a first region and a second region, the first region is located at a middle position of the crotch region, the second region is located at side positions of the crotch region, and a liquid absorption rate per unit area of the first region is greater than that of the second region. In one embodiment, the first region is configured to allow penetration therethrough and flow toward the absorption layer, and the second region at least partially uses a waterproof material and is configured to prevent lateral diffusion of liquid and prevent penetration of liquid to the absorption layer. In one embodiment, the first region is a one-way moisture-conducting fabric configured to allow liquid to penetrate unidirectionally from the wearer's body to the absorption layer, and the second region comprises a hydrophobic base layer and a waterproof adhesive layer laminated, with the hydrophobic base layer being closer to the wearer's skin than the waterproof adhesive layer. In one embodiment, the first region is a first portion of the base layer, the second region is a second portion of the base layer, the first portion has a third edge, the second portion has a fourth edge adjacent to the third edge, and the third edge and the fourth edge extend into the receiving space and are combined within the receiving space. In one embodiment, the fourth edge of the second portion is folded and extends into the receiv
