[0002] Current water outlets on the market, such as overhead showerheads, can take too long to drain completely after use. This residual water can easily breed bacteria, impacting the user experience. Especially when used in areas with poor water quality, prolonged accumulation of water within the showerhead can easily lead to the accumulation of dirt from the water's sedimentation. Therefore, even manual drainage cannot effectively remove particulate matter, and a clogged nozzle can not only cause water accumulation, scaling, and bacterial growth within the showerhead, but also cause the accumulated water to freeze in winter, shortening the product's lifespan.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0031] Example

[0032] Combine Figures 1 to 11 This embodiment provides a water outlet device that can quickly discharge residual water, including a water outlet body 1. The water outlet body 1 is provided with a water outlet surface cover 11 and a descaling needle 12. The water outlet surface cover 11 is provided with a water outlet nozzle 111 and a residual water drain port 112. A channel connected to the water outlet nozzle 111 is provided in the water outlet body 1. A piston member 13 controlled by water pressure is provided between the residual water drain port 112 and the channel. The descaling needle 12 moves relative to the water outlet nozzle 111 in the water outlet surface cover 11 in response to the water pressure, and is used to cooperate with the piston member 13 to move away from the water outlet nozzle 111 or insert into the water outlet nozzle 111.

[0033] The water outlet device mentioned above can automatically open the drain port after the water supply is stopped, quickly discharge the residual water, and avoid scale accumulation, through the water pressure-controlled piston member 13 set between the residual water drain port 112 and the channel, and the descaling needle 12 is linked with the piston member 13, and can automatically move away from the water outlet 111 when water is taken in, so as to keep the water outlet unobstructed. When the water supply is stopped, the descaling needle 12 is automatically inserted into the water outlet 111 to remove scale and impurities that may be attached to the water outlet 111, and maintain the cleanliness and smoothness of the water outlet device. The device is automatically controlled by water pressure and does not require manual intervention by the user, thereby realizing the automatic operation of the descaling and drainage functions, greatly improving the user's convenience and comfort.

[0034] In this embodiment, the piston member 13 has a first position abutting the residual water drain port 112 and a second position avoiding the residual water drain port 112. When water flows in, the piston member 13 adaptively switches to the first position to disconnect the channel from the residual water drain port 112. When water stops flowing in, the piston member 13 automatically returns to the second position to connect the channel to the residual water drain port 112, thereby draining the residual water.

[0035] like Figures 5 to 7 As shown, in this embodiment, the piston member 13 includes a plug 131, a spring member 132, and a sealing ring 133. The sealing ring 133 is relatively separated from the plug 131 and is arranged on the inner side wall of the residual water drain outlet 112. The sealing ring 133 is arranged in a similar shape to the residual water drain outlet 112. When the piston member 13 is in the first position, the plug 131 squeezes the spring member 132 to accumulate elastic reset force. The residual water drain outlet 112 and the plug 131 are both straight-line openings, and the diameter of the drain outlet is larger than the diameter of the water outlet 111. It is obvious that when water flows in, the force exerted by the water pressure on the plug 131 is always greater than the elasticity of the spring member 132, thereby overcoming the spring member 132 and pressing the plug 131 to the first position, thereby blocking the residual water drain outlet 112 and disconnecting it from the channel. When there is no water inflow or the water inflow stops, there is no water pressure force. At this time, the elastic restoring force of the spring member 132 returns the plug 131 to the second position, exposing the residual water drain port 112 to communicate with the channel.

[0036] In this embodiment, the descaling needle 12 can move up and down relative to the water outlet 111. When the residual water drain outlet 112 is disconnected from the channel, it moves upward away from the water outlet 111 to supply water for showering. When the residual water drain outlet 112 is connected to the channel, it moves downward to insert into the water outlet 111. Thus, the automatic up and down movement of the descaling needle 12 can effectively remove scale and impurities at the water outlet 111, ensuring that the showerhead remains unobstructed even after long-term use, avoiding water flow obstruction or blockage.

[0037] The hydraulic pressure control function of piston 13 automatically drains any remaining water from the channel after the water supply is stopped, preventing accumulation. This not only reduces scale formation but also helps prevent bacterial growth, improving shower hygiene. Furthermore, scale removal and residual water drainage are performed immediately after use, significantly reducing maintenance requirements, extending the showerhead's lifespan, and improving product durability. Furthermore, the entire process is automatically completed by water pressure, eliminating the need for manual operation by the user, making it more convenient and enhancing the user experience.

[0038] like Figures 1 to 5As shown, in this embodiment, the water outlet body 1 is configured as a shower head, and a water inlet connector 2 is movably connected to the back of the shower head, and the water inlet connector 2 is connected to the channel. The water outlet body 1 is also provided with a water distribution member 14 and a connecting member 15 movably connected to the water inlet connector 2. The connecting member 15 is provided with an extension portion 151, and the extension portion 151 covers the water distribution member 14 to form a water distribution cavity. Preferably, the extension portion 151 is directly formed integrally on the connecting member 15 to cover the water distribution member 14 to form the water distribution cavity, thereby enhancing the connection stability of the internal structural parts, helping to prevent water leakage when entering the water distribution member 14, and ensuring smooth input of water flow.

[0039] Specifically, the water diversion member 14 has a water inlet passage 141 connected to the water inlet joint, and a water outlet passage 142 connected to the water outlet nozzle 111, formed within the water diversion chamber. A movable chamber adapted to allow the piston member 13 to switch positions is provided at the connection point between the water inlet passage 141 and the water outlet 142. This movable chamber is connected to the residual water outlet 112. Obviously, the movable chamber serves the purpose of connecting the water passages, and on the other hand, allows the piston member 13 to freely switch positions within the chamber, thereby connecting the passage and disconnecting the residual water outlet 112, or disconnecting the passage and connecting the residual water outlet 112.

[0040] When the piston member 13 is switched to the first position, the residual water drain port 112 is blocked by the piston member 13, and the movable cavity is connected to the water inlet 141 and the water outlet 142. When the piston member 13 is reset to the second position, the blockage of the residual water drain port 112 is released, and the movable cavity is connected to the water outlet and the residual water drain port 112, thereby achieving the function of draining residual water.

[0041] Furthermore, the connector 15 is provided with a water inlet 152 connected to the water inlet 141. The water diverter 14 is correspondingly provided with an inlet 143 connecting the water inlet 141 and the active chamber, an outlet 144 connecting the active chamber and the water outlet 142, and a water outlet 145 connected to the water outlet nozzle 111. When the piston 13 is in the first position, the inlet 143 and outlet 144 are connected to the active chamber. When the piston 13 returns to the second position, the inlet 143 and outlet 144 are disconnected from the active chamber.

[0042] It should be noted that, specifically, when the piston member 13 is in the first position, the inlet 143 and the outlet 144 are in communication with the active chamber. When the piston member 13 is reset to the second position, the inlet 143 and the outlet 144 are disconnected from the active chamber.

[0043] Preferably, the water inlet 152 and the water outlet 145 are arranged vertically opposite to each other below the connecting member 15, and the movable chamber and the residual water drain outlet 112 are arranged vertically opposite to each other on opposite sides of the connecting member 15. The water inlet 141 is formed on the end face of the water distribution member 14, and the water outlet 142 is correspondingly formed on both sides of the water inlet 141. Such a waterway layout makes the water flow path more compact and smooth, reduces the bending and resistance of the water flow, improves the efficiency of the water flow, and ensures the stability and uniformity of the water outlet. In addition, the water inlet 152 and the water outlet 145 arranged vertically opposite to each other can effectively reduce the water hammer effect, that is, the impact force generated when the water flow suddenly stops or changes direction, thereby reducing the wear on the internal components and extending the service life of the structure.

[0044] The water inlet 152 is provided in the form of a gap between the connector 15 and the water distribution member 14. At least three water outlets 145 are provided correspondingly on the central circumference of the water distribution member 14, and multiple water outlets 145 are arranged around the outside of the connector 15, further realizing a more compact and efficient water inlet and outlet arrangement.

[0045] In this embodiment, a chamber is formed between the descaling needle 12 and the water outlet 111, generating a buildup of pressure when water flows in. This chamber is connected to the water outlet 145, and a return spring 16 abuts against the top of the descaling needle 12. Water flowing into the chamber from the water outlet 145 is disconnected from the channel and the residual water drain 112, creating a sealed internal water storage space. This allows the descaling needle 12 to overcome the force of the return spring 16 and adaptively rise upward, clearing the water outlet 111 and allowing showering. When water stops flowing, the channel connects to the residual water drain 112, allowing the water in the chamber to be quickly discharged toward the residual water drain 112.

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, the water inlet connector 2 and the connector 15 are hingedly connected by a ball joint. The connector 15 has a threaded portion 153, on which a nut 17 is mounted for detachable connection to the water inlet connector 2. The hinged connection between the nut 17 and the water inlet connector 2 ensures that the entire water outlet cover 11 can rotate relatively freely. This not only facilitates adjustment of the shower angle, but also allows the residual water drain port 112 to be positioned below the water outlet 111 to create a height difference, further facilitating the rapid discharge of residual water.

[0047] like Figures 1 to 7 As shown, in this embodiment, the water outlet cover 11 of the shower body 1 is circular.

[0048] like Figures 8 to 11 As shown, in other embodiments, the water outlet cover 11 of the shower body 1 is rectangular.

[0049] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
