However, when walking on the beach, sand and gravel can easily enter the drainage channel inside the sole through the normally open side drainage hole, making it inconvenient for the wearer to clean and thus affecting the comfort of wearing them. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a slipper with a side drainage structure. This solves the problem that existing slippers, in order to improve drainage performance, have a drainage structure on one side. However, when walking on the beach, sand and gravel can easily enter the drainage channel inside the sole through the side drainage hole, which is always open, making it inconvenient for the wearer to clean and thus affecting the comfort of wearing the slipper.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a slipper with a side drainage structure, the structure of which includes a sole, an upper, and an anti-slip pad; the upper is connected to the front edge of the sole; the anti-slip pad is detachably connected to the top surface of the sole;
[0006] The sole has several drainage outlets arranged sequentially from front to back on both sides. The top surface of the sole has an assembly groove for attaching and positioning the bottom of the anti-slip pad. The bottom surface of the assembly groove has a drainage groove arranged longitudinally on both the left and right sides. The two drainage grooves are connected to the drainage outlets on both sides of the sole. The bottom surface of the drainage groove is provided with a detachable sealing component. The sealing component can be removed to seal several drainage outlets on the same side.
[0007] The anti-slip mat has several drainage micro-holes at both the front and back, corresponding to the drainage grooves.
[0008] Furthermore, to facilitate disassembly and assembly, the bottom surface of the anti-slip pad is provided with at least one elastic locking block, and the bottom surface of the assembly slot is provided with a locking groove that engages with the elastic locking block.
[0009] Furthermore, in order to seal the drain outlet, the sealing assembly includes an interlocking groove located on the bottom surface of the drainage ditch, a sealing strip sealing the opening of the interlocking groove, and a number of sealing posts disposed in the interlocking groove corresponding to the number of drain outlets on the same side. The number of sealing posts are simultaneously connected to the bottom surface of the sealing strip, and the inner wall of the drain outlet is provided with a sealing sleeve adapted to the sealing posts.
[0010] Furthermore, in order to improve the firmness of the connection between the sealing post and the sealing sleeve and to prevent the sealing post from falling off during vigorous exercise, the outer ring of the sealing post is provided with at least one retaining ring.
[0011] Furthermore, in order to ensure that the sealing post can be tightly nested inside the sealing sleeve, the inner diameter of the sealing sleeve is smaller than the diameter of the sealing post.
[0012] Furthermore, to improve support performance, the outer end of the drain outlet has a structure that is circular, elliptical, or polygonal.
[0013] Furthermore, to improve the stability of the structure, the elastic block and the anti-slip pad are integrally formed, with the upper part being a columnar structure and the lower part being a spherical structure that matches the slot.
[0014] The beneficial effects of this invention are as follows: When worn in the bathroom or outdoors in the rain, the drain outlet and the drainage channel are in a conductive state. Water entering the sole is guided into the drainage channel through the drainage micro-holes and finally discharged from the drain outlet on the side of the sole. When walking on the beach, the anti-slip mat can be removed from the mounting slot to expose the drainage channel. Then, by removing the sealing component on the bottom of the drainage channel, the sealing component is installed at the drain inlet end to seal it. Finally, the anti-slip mat is reinstalled, which can effectively prevent sand and gravel from entering the drainage channel and affecting the comfort of wearing the shoes. Attached Figure Description
