This not only significantly impacts the user experience, but the residual water also typically contains a significant amount of impurities and bacteria. When this water, containing impurities and bacteria, is sprayed onto the body again, it may pose a potential threat to the user's health, thus reducing the safety and practicality of the showerhead.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] This utility model provides a shower head residual water drainage structure, which solves at least the technical problem of how to quickly drain the residual water in the shower head.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A shower head residual water drainage structure includes: a shower head body, a fixed base, a central shaft, and an elastic element;

[0009] The shower head body is provided with a water distribution chamber, a water outlet and a drain hole, and the water outlet is connected to the water distribution chamber;

[0010] The fixing seat is located inside the shower head body and is fixedly connected to the shower head body.

The water inlet channel is connected to the drain hole, and the water passage hole is connected to the water distribution chamber.

[0011] The central shaft is movably disposed within the water inlet channel and is oriented toward the drain hole;

[0012] The elastic element is disposed between the fixed base and the central shaft, or between the shower head body and the central shaft;

[0013] In the initial state, the central shaft moves to a preset position under the elastic force of the elastic element, so that the drain hole, the water passage hole and the water distribution chamber are interconnected; in the use state, the central shaft moves towards the drain hole under the water pressure in the water inlet channel until the central shaft seals the drain hole.

[0014] In some embodiments, the shower head body includes a housing, a water sealing seat and a face cover fixedly disposed inside the housing, and a water distribution cavity is provided between the water sealing seat and the face cover; the face cover is provided with a drain hole and a water outlet hole; the water sealing seat is provided with a sleeve hole for sealing the fixed seat, and the fixed seat is fixedly connected to the water sealing seat.

[0015] In some embodiments, the elastic element is disposed between the cover and the central shaft; the inner side of the cover and the central shaft are provided with a first positioning structure and a second positioning structure for sleeved on the elastic element, wherein the first positioning structure and the second positioning structure are positioning posts or positioning holes, and are disposed opposite to each other.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the shower head residual water drainage structure provided by this utility model has the following beneficial effects:

[0022] During normal use, external water enters the water distribution chamber and inlet channel. Under water pressure, the central shaft automatically seals the drain hole, ensuring that water in the distribution chamber can only flow out through the outlet hole, effectively guaranteeing the showerhead's normal function. After use, the pressure inside the inlet channel gradually decreases, and the elastic element drives the central shaft to reset and open the drain hole, allowing residual water in the distribution chamber to be discharged through the water passage and drain hole. This quickly removes residual water from the distribution chamber, effectively preventing scale buildup and bacterial growth, thus improving the showerhead's hygiene performance.

[0023] Equally important, the central shaft is set inside the water inlet channel, which not only enables automatic control of its movement through water pressure, but also provides effective guidance and limitation through the water inlet channel, while simplifying the installation process and improving installation efficiency.

[0024] In summary, compared with the prior art, the shower head residual water drainage structure of this utility model has the advantages of rapid drainage, high hygiene performance, and convenient installation, which can effectively improve the user experience of the shower head.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] Existing showerheads leave residual water inside after use. This residual water can easily breed bacteria and limescale, affecting the user experience.

[0037] To solve the above-mentioned technical problems, this embodiment provides a shower head residual water drainage structure. Please refer to [link / reference]. Figures 1 to 4 As shown, Figure 1 This is a cross-sectional view of the shower head in its initial state in the embodiment. Figure 2 This is a 3D view of the shower head in its initial state in the embodiment. Figure 3This is a cross-sectional view of the shower head in use, as shown in the embodiment. Figure 4 This is a perspective view of the shower head in use, as shown in the embodiment.

[0038] This embodiment of a shower head residual water drainage structure includes: a shower head body 1, a fixed base 2, a central shaft 3, and an elastic element 4.

[0039] The shower head body 1 is provided with a water distribution chamber 11, a water outlet 12 and a drain hole 13. The water outlet 12 is connected to the water distribution chamber 11 and is used to discharge the water in the water distribution chamber 11 when the shower head is in use, thereby forming shower water. The drain hole 13 is used to discharge the residual water in the water distribution chamber 11 after use.

[0040] The fixing seat 2 is located inside the shower body 1 and is fixedly connected to the shower body 1. The fixing seat 2 is provided with an inlet channel 21 and a water passage hole 22 that are interconnected. The inlet channel 21 is connected to the drain hole 13 and is used to input external water source. The water passage hole 22 is connected to the water distribution chamber 11.

[0041] The central shaft 3 is movably disposed within the water inlet channel 21 and is positioned toward the drain hole 13. Its movement is automatically controlled by the water pressure within the water inlet channel 21 and the elastic force of the elastic element 4.

[0042] The elastic element 4 is located between the fixed base 2 and the central shaft 3, or between the shower body 1 and the central shaft 3.

[0043] Among them, such as Figure 1 and Figure 2 As shown, in the initial state, the central shaft 3 moves to a preset position under the elastic force of the elastic element 4, and the drain hole 13 opens, so that the drain hole 13, the water passage hole 22 and the water distribution chamber 11 are interconnected; in the use state, as... Figure 3 and Figure 4 As shown, the central shaft 3 moves toward the drain hole 13 under the pressure of water in the water inlet channel 21 until the central shaft 3 seals the drain hole 13.

[0044] When the shower head using the above technical solution is in use, external water enters the water distribution chamber 11 and the water inlet channel 21. The central shaft 3 moves towards the drain hole 13 under the pressure of the water inlet channel 21. When the water pressure in the water inlet channel 21 reaches a certain value, the central shaft 3 seals the drain hole 13, allowing water in the water distribution chamber 11 to flow out through the outlet hole 12 but not through the drain hole 13, thus ensuring normal shower head function. After use, the pressure inside the water inlet channel 21 gradually decreases to zero. During this process, the elastic element 4 drives the central shaft 3 to move and reset, opening the drain hole 13 and connecting the drain hole 13, the water passage hole 22, and the water distribution chamber 11. At this time, residual water in the water distribution chamber 11 can pass through the water passage hole 22 and drain out through the drain hole 13, thereby accelerating the drainage speed. Equally important, the central shaft 3 is located within the water inlet channel 21, allowing for automatic movement control by the water pressure inside the channel, as well as guidance and limiting by the channel, while also facilitating quick installation of the central shaft 3. As can be seen, the above technical solution's showerhead residual water drainage structure can quickly drain the residual water inside the showerhead and has the advantage of easy installation.

[0045] It is understandable that the specific water path of the shower body 1 to introduce external water source into the water inlet channel 21 and the water distribution chamber 11 can be realized by using the existing shower water path structure, and can be selected as needed, which will not be elaborated here.

[0046] In one embodiment where the shower head body 1 is provided with a water distribution chamber 11, a water outlet 12, and a drain hole 13, and the fixing base 2 is located inside the shower head body 1 and is fixedly connected to the shower head body 1, see reference. Figure 1 and Figure 2 As shown, the shower head body 1 includes a housing 14, and a water sealing seat 15 and a face cover 16 fixedly disposed inside the housing 14. A water distribution chamber 11 is provided between the water sealing seat 15 and the face cover 16. The face cover 16 is provided with a drain hole 13 and a water outlet hole 12. The water sealing seat 15 is provided with a sleeve hole for sealing and mounting a fixing seat 2. The fixing seat 2 is fixedly connected to the water sealing seat 15. In this way, the fixing seat 2 can be directly fitted into the sleeve hole for positioning during installation and fixedly connected to the fixing seat 2, making installation more convenient.

[0047] For example, see Figure 1 and Figure 2 As shown, the water distribution seat includes a relatively fixed rear water seal seat 151 and a face cover water distribution seat 152. A cavity for inputting external water source is formed between the rear water seal seat 151 and the face cover water distribution seat 152. The cavity is connected to the water inlet channel 21. The fixed seat 2 is fixedly connected to the rear water seal seat 151. The face cover water distribution seat 152 and the face cover 16 are relatively fixed and form a water distribution cavity 11 between them. Of course, a water outlet sleeve can also be provided on the inner side of the face cover 16, and the water outlet hole 12 is opened on the water outlet sleeve.

[0048] For example, the water distribution seat is fixed to the rear water seal seat 151 by means of screw connection, snap connection or swivel connection.

[0049] In one installation method of the aforementioned elastic element 4, see [reference needed]. Figure 1 and Figure 3 As shown, the elastic element 4 is a compression spring, which is located between the cover 16 and the central shaft 3, and drives the central shaft 3 to move by forming an elastic force through compression. The inner side of the cover 16 and the central shaft 3 are provided with a first positioning structure 17 and a second positioning structure 31 for sleeved elastic element 4. The first positioning structure 17 and the second positioning structure 31 are positioning posts or positioning holes, and are arranged opposite to each other, which can effectively improve the ease of installation of elastic element 4 and the stability during operation.

[0050] In another installation method of the above-mentioned elastic element 4 (not shown in the figure), the elastic element 4 is a tension spring and is located between the fixed base 2 and the central shaft 3. One end of the tension spring is connected to the fixed base 2 and the other end is connected to the central shaft 3. The central shaft 3 is driven to move to the initial preset position by the elastic tension.

[0051] It is understood that the aforementioned elastic element 4 can also be other components with elastic deformation capabilities, such as elastic blocks or spring sheets, and can be installed in the manner described above as compression springs or tension springs.

[0052] For example, the water inlet channel 21 extends along the length of the fixed base 2 and forms an opening at the end of the fixed base 2, with the opening facing the drain hole 13, so that when the central shaft 3 moves in the water inlet channel 21, it can move toward the drain hole 13; at this time, the water passage hole 22 is opened on the side of the fixed base 2.

[0053] In one embodiment of the sealing drainage hole 13 of the central shaft 3 described above, see [reference needed]. Figure 2 and Figure 3 As shown, a sealing ring 5 is provided on the inner side of the drain hole 13. In use, the central shaft 3 seals the drain hole 13 through the sealing ring 5.

[0054] For example, see Figure 2 As shown, the sealing ring 5 is fixed inside the drain hole 13, and a boss 51 is provided at one end facing the central shaft 3. The boss 51 has a compression spring and a water flow clearance hole 52 in the middle. When the central shaft 3 abuts against the boss 51, it seals the clearance hole 52, thereby sealing the drain hole 13.

[0055] Understandably, the sealing ring 5 can also be fixed to one end of the central shaft 3 near the drain hole 13, and seal the drain hole 13 by making sealing contact with the inside of the faceplate 16.

[0056] To facilitate the movement of the central shaft 3 to the preset position under the elastic force of the elastic element 4, please refer to... Figure 1 and Figure 2As shown, the fixed base 2 has a limiting part 23 inside the water inlet channel 21. In the initial state, the central shaft 3 moves to contact the limiting part 23 under the elastic force of the elastic member 4, thereby abutting against the limiting part 23 and limiting itself to a preset position.

[0057] For example, the limiting part 23 is a shoulder structure integrally formed inside the water inlet channel 21.

[0058] To improve the rate of residual water drainage, see [link / reference]. Figure 1 and Figure 2 As shown, the water outlet cross-section of drain hole 13 is larger than that of drain hole 12.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
