If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Understandably, referring to Figure 1 , Figure 2 and Figure 3The drainage mechanism of the first aspect of this utility model includes a connecting shell 100 and a drainage assembly 200. The connecting shell 100 is provided with an inlet 110, an outlet 120, and a first drainage outlet 130, which is arranged between the inlet 110 and the outlet 120. The drainage assembly 200 includes a fixing base 210 and a connecting block 220, both of which are fixedly connected to the connecting shell 100. A second drainage outlet 230 is provided between the fixing base 210 and the connecting block 220. The first drain outlet 130 is connected to the second drain outlet 230. The connecting block 220 is connected to an elastic member 221. The elastic member 221 extends axially along the connecting block 220 and can deform radially along the connecting block 220 to block or open the second drain outlet 230. When the elastic member 221 abuts against the end face of the second drain outlet 230, the inlet 110 is connected to the outlet 120. When the elastic member 221 is separated from the second drain outlet 230, the outlet 120 is connected to the second drain outlet 230.

[0033] The fixed base 210 and the connecting block 220 are both fixedly connected to the connecting shell 100. The connecting shell 100 is provided with an inlet 110, an outlet 120 and a first drain outlet 130. A second drain outlet 230 is provided between the fixed base 210 and the connecting block 220. An elastic member 221 is connected to the connecting block 220. The elastic member 221 extends along the axial direction of the connecting block 220 and can deform radially along the connecting block 220, so that the elastic member 221 can block or open the second drain outlet 230. When water flows in from the inlet 110, the water flow expands the elastic element 221, allowing the elastic element 221 to deform outward along the radial direction of the connecting block 220, thereby blocking the second drain outlet 230 and connecting the inlet 110 and the outlet 120, allowing water to flow sequentially. When the water flow stops, the elastic element 221 resets and separates from the second drain outlet 230, connecting the outlet 120 and the second drain outlet 230, allowing water to flow sequentially from the second drain outlet 230 and the first drain outlet 130, preventing water accumulation and facilitating the drainage of water remaining inside the shower head, thus improving the user experience.

[0034] It should be noted that, referring to Figure 5The water source, drainage mechanism, hose 300, and shower head are connected in sequence. When the water source delivers water to the shower head, the water flows in through the inlet 110 of the connecting shell 100 and through the connecting block 220, causing the elastic element 221 to deform outward along the radial direction of the connecting block 220. This allows the elastic element 221 to block the second drain outlet 230, thus enabling the water to flow smoothly from the inlet 110 to the outlet 120 and preventing water from flowing out of the first drain outlet 130. When the water source is turned off, the elastic element 221 deforms inward along the radial direction of the connecting block 220 to reset, opening the second drain outlet 230. This allows the outlet 120 to connect with the second drain outlet 230, enabling the water in the hose 300 and shower head to be discharged from the first drain outlet 130, preventing water from remaining in the hose 300 and shower head and improving the user experience.

[0035] Among them, the elastic element 221 can be an elastic element such as a rubber element or a silicone element, and is not limited here.

[0036] Understandably, referring to Figure 2 and Figure 4 The fixing base 210 has multiple protrusions 211 near the connecting block 220. These protrusions 211 are spaced apart circumferentially along the fixing base 210 and abut against the connecting block 220. A second drain outlet 230 is formed between two adjacent protrusions 211. The multiple protrusions 211 spaced apart circumferentially along the fixing base 210, and their abutment against the connecting block 220, create a second drain outlet 230 between adjacent protrusions 211. These multiple second drain outlets 230 disperse the water flow, promoting even drainage, improving drainage efficiency, preventing water accumulation due to poor drainage, and enhancing the reliability of the drainage mechanism.

[0037] Specifically, refer to Figure 1 and Figure 2 The number of first drain outlets 130 is set to multiple, and the multiple first drain outlets 130 are arranged at intervals along the circumference of the connecting shell 100. The multiple first drain outlets 130 work simultaneously, so that water can be discharged quickly from multiple directions, effectively avoiding the problems of poor drainage and water accumulation that may occur with a single first drain outlet 130, reducing drainage time, reducing the time that residual water stays in the shower head and hose 300, thereby improving drainage efficiency.

[0038] In addition, multiple first drain outlets 130 are arranged at intervals along the circumference of the connecting shell 100 so that water can be discharged from multiple directions, and the connecting shell 100 can be conveniently drained in any posture, reducing the possibility of water residue and improving the convenience of use.

[0039] Specifically, refer to Figure 2 and Figure 4The elastic element 221 has an annular cross-sectional shape, and its thickness gradually increases towards the fixed seat 210 along its axial direction. The annular elastic element 221 provides a more uniform contact surface with the second drain outlet 230, allowing for better fit to the end face of the second drain outlet 230, improving sealing performance, preventing water leakage from the second drain outlet 230 during normal water supply, ensuring smooth water flow from the inlet 110 to the outlet 120, and guaranteeing the normal operation of the shower head.

[0040] In addition, the thickness of the elastic element 221 gradually increases towards the fixed base 210, which makes the elastic element 221 have stronger elasticity and support force near the fixed base 210. This can maintain structural stability during deformation, avoid failure and damage caused by excessive deformation, extend service life, and improve reliability.

[0041] Understandably, referring to Figure 2 and Figure 4 The drainage assembly 200 also includes a sealing gasket 240, which is disposed between the fixing seat 210 and the connecting block 220. The sealing gasket 240 effectively fills the tiny gap between the fixing seat 210 and the connecting block 220, preventing water from seeping in through this gap, avoiding external impurities from entering the connecting shell 100, maintaining the water supply stability of the drainage mechanism, and improving reliability.

[0042] Specifically, refer to Figure 2 and Figure 3 The drainage assembly 200 also includes a connecting cylinder 250, with a connecting block 220 disposed within the connecting cylinder 250. A first retaining ring 251 protrudes from the inner wall of the connecting cylinder 250, and a second retaining ring 212 is provided on the fixing seat 210. The first retaining ring 251 can engage with the second retaining ring 212. By fitting the connecting cylinder 250 onto the fixing seat 210, allowing the first retaining ring 251 to abut against the second retaining ring 212, and by further pressing the connecting cylinder 250, the first retaining ring 251 can pass over the second retaining ring 212, thus enabling the first retaining ring 251 and the second retaining ring 212 to engage. This allows the connecting cylinder 250 to be fixed together with the fixing seat 210 without the need for fasteners, improving installation convenience.

[0043] The connecting block 220 is arranged inside the connecting cylinder 250, and the sealing gasket 240 is arranged between the fixing seats 210 of the connecting block 220, so that the connecting cylinder 250 can drive the connecting block 220 to press the sealing gasket 240 onto the fixing seat 210, thereby absorbing the gap between the fixing seat 210 and the connecting block 220 and improving the sealing performance.

[0044] In addition, the sealing gasket 240 can be an elastic component such as rubber or silicone, which can push the connecting cylinder 250 to move away from the connecting block 220 so that the first retaining ring 251 and the second retaining ring 212 can be stably together, which can prevent the position of the connecting cylinder 250 from loosening and improve the stability of the installation.

[0045] Understandably, referring to Figure 2 and Figure 4 The mounting base 210 has an installation groove 213, and a sealing ring 214 is connected to the installation groove 213. The sealing ring 214 is sealed to the connecting shell 100. The mounting base 210 has an installation groove 213, and the sealing ring 214 is arranged in the installation groove 213 so that the sealing ring 214 can abut against the connecting shell 100, so that the sealing ring 214 can seal between the mounting base 210 and the connecting shell 100, preventing water from seeping in from the gap between the mounting base 210 and the connecting shell 100, and ensuring the normal use of the shower head.

[0046] In addition, by setting the sealing ring 214 in the mounting groove 213, the position of the sealing ring 214 can be stabilized, preventing the sealing ring 214 from shifting or loosening, reducing the possibility of water leakage, and improving the reliability of the drainage mechanism.

[0047] Understandably, referring to Figure 2 and Figure 4 The inlet 110 is equipped with a mesh 140 for filtering water. By installing the mesh 140 at the inlet 110, impurities in the water can be effectively intercepted, preventing them from entering the drainage mechanism. This not only avoids wear and blockage of components such as the elastic element 221, the fixed seat 210, and the connecting block 220, extending their service life, but also reduces the risk of the second drain outlet 230 becoming blocked, ensuring smooth drainage operation and improving the reliability of the drainage mechanism.

[0048] Understandably, referring to Figure 1The outer wall of the connecting shell 100 is provided with multiple anti-slip protrusions 150, which are arranged along the axial direction of the connecting shell 100 and surround the connecting shell 100. The arrangement of multiple anti-slip protrusions 150 around the connecting shell 100 increases the friction of the outer wall of the connecting shell 100, making it easier for users to hold the connecting shell 100 during operation. This effectively prevents slippage between the hand and the connecting shell 100, allowing users to grip the connecting shell 100 more firmly, thus completing the installation action more accurately and easily, improving installation efficiency and accuracy, and reducing installation errors and repetitive operations caused by slippage.

[0049] It should be noted that the water source can be threadedly connected to the connecting shell 100 through a connector, so that when the connecting shell 100 is rotated, it can be tightened into the connector, thereby facilitating the installation of the drainage mechanism. By setting multiple anti-slip protrusions 150 on the connecting shell 100, it helps the user to grip the connecting shell 100, making the installation operation easier and improving the convenience of installation.

[0050] Understandably, referring to Figure 5 The shower head assembly of the second aspect of this utility model includes the drainage mechanism of the first aspect of this utility model. Since it has all the technical features of the drainage mechanism of this embodiment, it also has the beneficial effects of all the above embodiments, which will not be repeated here.

[0051] It should be noted that the shower assembly includes a hose 300, a shower head, and a drainage mechanism. One end of the hose 300 is connected to the drainage mechanism, and the other end is connected to the shower head. When the water source is turned on, the water flow can push the elastic element 221 to deform radially outward and block the second drain port 230, allowing the water flow to pass through the inlet 110, outlet 120, hose 300, and shower head in sequence, so that the water flow can be smoothly output from the shower head. When the water source is turned off, the elastic element 221 returns to its original position and separates from the second drain port 230, allowing the water in the shower head and hose 300 to flow out through the second drain port 230 and the first drain port 130 in sequence, preventing water from accumulating in the hose 300 and shower head, and improving the user experience.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
