[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] refer to Figures 1 to 5 As shown, a drainage module 1 includes a drainage module 1 arranged between a shower rod 22 and a shower body 23, the drainage module 1 includes a drainage member 11 and an elastic member 12, the elastic member 12 is movably sleeved in the drainage member 11, a water passage 121 is arranged in the elastic member 12, a drainage channel 111 matched with the elastic member 12 is arranged on the inner side of the drainage member 11, the elastic member 12 and the drainage channel 111 are connected with clearance, specifically, the gap between the elastic member 12 and the drainage member 11 is a water passage gap 113, that is, the elastic member 12 has a suitable gap with the drainage member 11 in the initial state, a drainage hole 112 is arranged on the peripheral wall of the drainage member 11, and the water passage 121 can be connected with the drainage hole 112 through the water passage gap 113.

[0028] When the shower is running normally, the elastic member 12 will be elastically stretched due to the impact of the water flow on the inner wall of the water channel 121, which will increase the impact force and pressure on the inner wall of the water channel 121, and the elastic member 12 will be close to the drainage member 11, and the elastic member 12 will cooperate to block the drainage hole 112, thereby cutting off the connection between the water channel 121 and the drainage hole 112; when the shower stops running, the elastic member 12 returns to its original state and elastically separates from the drainage member 11 due to the water pressure in the shower rod 22, which will cooperate to open the drainage hole 112 on the drainage member 11, and then the connection between the water channel 121 and the drainage hole 112 will be achieved, so that the residual water in the shower rod 22 will be discharged through the drainage hole 112, thereby performing the drainage operation. Specifically, after the elastic member 12 is expanded, the drainage hole 112 is sealed, and the elastic member 12 can drain water when it returns to its initial state. In this way, the residual water in the shower pipe can be automatically discharged after the user turns off the top shower 21. In addition, the present application has a compact structure, requires less space to be reserved for the main body, has a simple, practical and low cost structure, and provides users with a better user experience.

[0029] Based on the above technical solution, the elastic member 12 is preferably configured so that the cross-section decreases successively along the water inlet direction, the water passage 121 provided in the elastic member 12 correspondingly decreases successively along the water inlet direction, and the drainage channel 111 decreases successively along the water inlet direction. In this way, when the shower is discharged normally, the elastic member increases successively along the water flow direction, and the pressure also increases accordingly. The elastic member is more ideally expanded, and the elastic member can better cooperate with the drainage member 11 to cling to the drainage member 11 and cut off the connection between the water passage 121 and the drainage hole 112. Conversely, after the water is stopped, the residual water can be better discharged.

[0030] For the same purpose, further, the elastic member 12 is preferably configured in a cone shape, and the drainage channel 111 and the water passage 121 are correspondingly configured in an inner cone shape. Specifically, the elastic member 12 is disposed inside the drainage member 11, and is overall cone-shaped, with the inner diameter gradually decreasing along the water inlet direction. There is a small gap between the elastic member 12 and the drainage member 11 in the initial state, and the elastic member 12 can exist in two states: outward expansion or inward contraction, that is, the elastic member 12 is subjected to the outward expansion force F1 to seal the drainage hole 112, and the inward contraction force F2 is applied to restore the initial state or contract inwardly to deform and open the drainage hole 112. Specifically, when the product's top spray 21 is normally discharging water, such as Figure 3 Due to the impact of the water flow and the tapered design of the elastic member 12, the elastic member 12 or the inner wall of the water passage 121 thereof will be subjected to a large pressure, so that the elastic member 12 is stretched open to seal the drainage holes 112 around the drainage member 11. At this time, the top shower 21 discharges water normally. When the top shower 21 of the product is closed, Figure 4, the elastic member 12 returns to its initial state. At this time, there is a small gap around the elastic member 12 and the drainage member 11. The residual water in the shower rod 22 can be discharged from the gap. At the same time, due to the gravity of the water itself acting on the elastic member 12, the elastic member 12 will be squeezed and deformed inward, increasing the gap between the elastic member 12 and the drainage member 11.

[0031] In an optional embodiment, when the shower is running normally, the elastic member 12 is elastically expanded and pressed against the drain hole 112 due to the impact of water flow on the inner wall of the water channel 121 , and the elastic member 12 can block the drain hole 112 , thereby cutting off the connection between the water channel 121 and the drain hole 112 .

[0032] In an optional embodiment, when the shower is running normally, the elastic member 12 is elastically stretched open and pressed against the inner wall of the drainage member 11 due to the impact of water flow on the inner wall of the water channel 121 , and the elastic member 12 blocks the water gap 113 , thereby cutting off the connection between the water channel 121 and the drainage hole 112 .

[0033] Furthermore, the inner wall of the drainage channel 111 is preferably provided with a circumferential groove 113, so that the elastic member 12 and the drainage channel 111 are connected with each other with a clearance fit. Further, a gap can be formed between the elastic member 12 and the drainage channel 111 when the shower stops, and the water flow can be discharged from the gap.

[0034] For the purpose of sealing and preventing water leakage, the outer side of the drain member 11 is provided with a sealing ring 114 and a groove 115 for fitting the sealing ring 114 at both ends along the water flow direction. It can be understood that any solution that can fix the sealing ring 114 is feasible.

[0035] Furthermore, a circumferential boss 122 is provided at the lower end of the elastic member 12 , and the circumferential boss 122 is overlapped and fixed to the lower end of the drainage member 11 , so that the elastic member 12 can be limited and fixed by the circumferential boss 122 after being sleeved on the drainage member 11 .

[0036] The present application also discloses a matching shower 2, including a shower 2 provided with a drainage module 1, the drainage module 1 is arranged inside the shower 2, the shower 2 also includes a top spray 21, a shower rod 22 and a shower body 23, when the shower is normally discharged, the water inlet channel of the top spray 21 is connected with the water passage 121, when the shower stops, the water inlet channel of the top spray 21 is connected with the drainage hole 112, and then the residual water in the water inlet channel of the top spray 21 is discharged through the drainage hole 112.
