[0002] In existing special shoes, especially those used in water for a long time, the problem of water filling in the shoes often occurs, which affects the movement and wearing experience. Therefore, draining the accumulated water in the shoes becomes the main problem.

[0003] For existing shoes with a drainage function, such as a work shoe disclosed in the patent with the publication number CN205106521U, through holes are provided on the side where the shoe upper and the sole are joined. In rainy days or when playing in water, it is convenient for drainage and ventilation. However, when wading through water, if the water level is higher than the through holes and lower than the shoe upper, without the through holes, water will not enter the shoes, but due to the presence of the through holes, a large amount of water will enter the shoes through the through holes, affecting the wearing experience. Content of the Utility Model

[0004] Based on this, in view of the above technical problems, it is necessary to provide a shoe sole with a drainage function.

[0005] In order to achieve the above object, the utility model provides a shoe sole with a drainage function, including a sole body. A ring groove adapted to its contour is provided at the upper edge of the sole body. A plurality of vertical holes are provided at the bottom of the ring groove. The inner diameter of the top end of the vertical hole is smaller than that of the bottom end. Drainage holes corresponding to and communicating with the vertical holes one by one are provided on the side wall of the sole body. A diversion plug is detachably installed in the drainage hole. A through diversion hole is provided in the middle of the diversion plug. A blocking floating ball is movably arranged in the vertical hole. The ball diameter of the blocking floating ball is larger than the inner diameter of the top end of the vertical hole and the inner diameter of the diversion hole, and the ball diameter of the blocking floating ball is smaller than the inner diameter of the bottom end of the vertical hole and the inner diameter of the drainage hole.

[0006] Preferably, the vertical hole is a tapered hole, and the inner diameter of the top end of the vertical hole is smaller than that of the bottom end.

[0007] Preferably, the diversion hole is inclined, and the upper inclined end of the diversion hole communicates with the bottom of the vertical hole.

[0008] Preferably, the diversion plug is in elastic interference fit with the drainage hole.

[0009] Preferably, a transverse water guide groove and a longitudinal water guide groove are provided on the sole body and inside the ring groove. Both the transverse water guide groove and the longitudinal water guide groove communicate with the ring groove.

[0010] Preferably, the transverse water guide groove has a structure that is high in the middle and low at both ends.

[0011] Preferably, the cross-section of the ring groove is U-shaped.

[0012] Beneficial effects of the present technical solution: The accumulated water on the sole body enters the vertical holes through the annular grooves and then is discharged through the diversion holes, maintaining the comfort of the sole body;

[0013] When wading in shallow water, the water outside the shoes flows back into the vertical holes through the diversion holes. The blocking floating ball will rise in the vertical holes under the action of the thrust and buoyancy of the water until it blocks the upper part of the vertical holes, preventing the water from flowing back into the shoes and playing a role in preventing backflow, thus maintaining the comfort inside the shoes;

[0014] The diversion holes and the vertical holes are arranged in an L shape, which can block foreign matters from entering the shoes, making the shoes with this sole body safer and more comfortable to wear. Description of the Drawings

[0018] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed embodiment of the present utility model with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0019] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a sole with a drainage function, including a sole body 1. An annular groove 2 adapted to its contour is provided at the upper edge of the sole body 1. A plurality of vertical holes 3 are provided at the bottom of the annular groove 2. The inner diameter of the top end of the vertical hole 3 is smaller than that of its bottom end. Specifically, the vertical hole 3 is a tapered hole. In other embodiments, the vertical hole 3 can also be set as a stepped hole; a drain hole 4 corresponding to and communicating with the vertical hole 3 is provided on the side wall of the sole body 1. A diversion plug 5 is detachably installed in the drain hole 4. A through diversion hole 6 is provided in the middle of the diversion plug 5. A blocking floating ball 7 is movably provided in the vertical hole 3. The ball diameter of the blocking floating ball 7 is larger than the inner diameter of the top end of the vertical hole 3 and the inner diameter of the diversion hole 6, and the ball diameter of the blocking floating ball 7 is smaller than the inner diameter of the bottom end of the vertical hole 3 and the inner diameter of the drain hole 4.

[0020] When the drainage hole 4 is not equipped with the flow guide plug 5, the flow-blocking float 7 is placed into the vertical hole 3 through the drainage hole 4, and then the flow guide plug 5 is installed; when debris enters the vertical hole 3, the flow guide plug 5 can be pulled out, and the flow-blocking float 7 and the debris in the vertical hole 3 can be discharged from the drainage hole 4 by jetting, spraying water or moving a lever;

[0021] After the upper is installed on the sole body 1, the shoe is made. When water accumulates inside the shoe, the accumulated water enters the vertical hole 3 through the annular groove 2 and is then discharged through the guide hole 6 to maintain the comfort inside the shoe. When wading in shallow water, the external water flows back into the vertical hole 3 through the guide hole 6. The blocking float 7 is made of plastic and can float on the water. The blocking float 7 is subjected to the thrust and buoyancy of the water and rises in the vertical hole 3 until it blocks the upper part of the vertical hole 3, thereby preventing the water from flowing back into the shoe and preventing the backflow. Moreover, the guide hole 6 and the vertical hole 3 are arranged in an L shape, thereby preventing foreign debris from entering the shoe, making the shoe safer and more comfortable to wear.

[0022] In a preferred embodiment, in order to improve the drainage effect of the guide hole 6 and avoid water accumulation in the guide hole 6, please refer to Figure 2 The drainage hole 4 is arranged at an angle, the upper end of the guide hole 6 is connected with the bottom of the vertical hole 3, the guide plug 5 is a rotating body structure, and after the guide plug 5 is installed to the drainage hole 4, the guide hole and the drainage hole 4 remain roughly coaxial, and the water in the vertical hole 3 can be naturally discharged from the guide hole 6 under gravity.

[0023] In a preferred embodiment, in order to facilitate the detachable connection between the guide plug 5 and the drain hole 4, an elastic interference fit is provided between the guide plug 5 and the drain hole 4. The guide plug 5 is made of rubber and has a certain elasticity, so that it can be inserted into the drain hole 4 by elastic interference fit. The guide plug 5 will not be easily separated from the drain hole 4, and a large force can be applied to pull the guide plug 5 out of the drain hole 4.

[0024] In a preferred embodiment, in order to facilitate the drainage of the water on the upper end surface of the sole body 1, please refer to Figure 1 and Figure 2 , a transverse water guide groove 8 and a longitudinal water guide groove 9 are arranged on the sole body 1 and located inside the annular groove 2, and both the transverse water guide groove 8 and the longitudinal water guide groove 9 are connected to the annular groove 2. The accumulated water on the upper end surface of the sole body 1 due to sweating or water ingress will enter the transverse water guide groove 8 and the longitudinal water guide groove 9, and then enter the annular groove 2, and then be discharged from the vertical hole 3 and the diversion port; by arranging the transverse water guide groove 8, the longitudinal water guide groove 9, the annular groove 2, the vertical hole 3 and the diversion hole 6, the ventilation of the sole body 1 can be achieved, and the wearing comfort can be improved.

[0025] To further improve the drainage efficiency of the transverse water channel 8, refer to 2, the transverse water channel 8 is set to have a structure with a high middle and low ends. Under the action of gravity, the water in the transverse water channel 8 flows from high to low and naturally flows to the annular groove 2.
