[0049] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] Example 1

[0051] like Figures 1 to 12 As shown, the present invention provides a water outlet device, including a water outlet pipe 1, an exhaust pipe 2, and a mounting base 3. The water outlet pipe 1 has a water outlet channel 100, the exhaust pipe 2 passes through the water outlet channel 100, and the exhaust pipe 2 has an exhaust channel 200. The mounting base 3 is mounted on the water outlet pipe 1 and connected to the exhaust pipe 2. The mounting base 3 has a mixing channel 300. One end of the water outlet channel 100 is connected to the outside through an inlet 101, and the other end is connected to one end of the mixing channel 300. The other end of the mixing channel 300 is connected to the outside through an outlet 3151. An air storage area 102 is provided at the top of the water outlet channel 100, and the air storage area 102 is positioned higher than the inlet 101 and the outlet 3151. One end of the exhaust channel 200 is connected to the air storage area 102, and the other end is connected to the mixing channel 300.

[0052] In this invention, by inserting an exhaust pipe 2 inside the water outlet pipe 1 and connecting both the water outlet pipe 1 and the exhaust pipe 2 to the mounting base 3, the water outlet channel 100 and the exhaust channel 200 are connected to the mixing channel 300 on the mounting base 3. The water outlet 3151 is connected through the mixing channel 300. The flow cross-sectional area of ​​the mixing channel 300 is smaller than that of the water outlet channel 100. When water flows through the water outlet channel 100 into the mixing channel 300, a negative pressure zone is formed by utilizing the Venturi effect. The air in the air storage zone 102 can be drawn in through the exhaust channel 200, so that the water outlet device can discharge the air accumulated at the top of the water outlet channel 100 during the water outlet process. When there is no residual air or very little residual air in the air storage zone 102, the water outlet device can be turned off immediately without causing continuous water flow.

[0053] Specifically, the flow cross-sectional area of ​​the mixing channel 300 is smaller than that of the outlet channel 100. This arrangement ensures the reliable realization of the Venturi effect when water flows through the outlet channel 100 into the mixing channel 300.

[0054] Specifically, such as Figure 2 and Figure 3 As shown, the mounting base 3 includes a fixed support 31 and a movable support 32. The fixed support 31 is fixedly connected to the water outlet pipe 1, and the movable support 32 is fixedly connected to the vent pipe 2. The movable support 32 is detachably connected to the fixed support 31. This arrangement allows the vent pipe 2 to be flexibly disassembled and maintained relative to the water outlet pipe 1.

[0055] More specifically, such as Figure 4 , Figure 5 and Figure 6 As shown, the fixed support 31 is provided with an installation channel 311. One end of the installation channel 311 is connected to the water outlet channel 100, and the other end is connected to the water outlet 3151. The inner wall of the installation channel 311 and the outer wall of the movable support 32 are each provided with an installation groove 312 and an installation protrusion 3211, respectively. The installation protrusion 3211 is engaged in the installation groove 312, and the installation groove 312 limits the movement of the installation protrusion 3211 along the axis of the installation channel 311. This configuration allows the movable support 32 to be more easily and quickly assembled and disassembled on the fixed support 31.

[0056] More specifically, the mounting groove 312 is annular and arranged around the axis of the mounting channel 311, and multiple mounting protrusions 3211 are provided, which are evenly distributed around the axis of the mounting channel 311. This arrangement makes the installation of the movable support 32 in the mounting channel 311 more stable and reliable.

[0057] In this embodiment, the mounting groove 312 is disposed on the inner wall of the mounting channel 311, and a plurality of mounting protrusions 3211 are disposed on the outer wall of the movable support 32. When the movable support 32 is inserted into the mounting channel 311, it first deforms elastically and then elastically resets at the position of the mounting groove 312, so that the plurality of mounting protrusions 3211 extend into the mounting groove 312.

[0058] In other embodiments, multiple mounting protrusions 3211 may be disposed on the inner wall of the mounting channel 311, and mounting grooves 312 may be disposed on the outer wall of the movable support 32.

[0059] Specifically, such as Figure 4 , Figure 5 and Figure 6 As shown, the fixed support 31 is provided with a connecting port 313 that connects the water outlet channel 100 and the water outlet 3151. On the inner wall of the connecting port 313 and the outer wall of the movable support 32, a positioning groove 314 is provided on one side and a positioning protrusion 3221 on the other. The positioning protrusion 3221 is confined within the positioning groove 314, which restricts the positioning protrusion 3221 from rotating around the axis of the connecting port 313. This arrangement makes the positioning of the movable support 32 relative to the fixed support 31 more precise and reliable, preventing the exhaust pipe 2 from being misaligned relative to the air storage area 102, thus avoiding any disruption to the exhaust operation.

[0060] More specifically, such as Figure 7 and Figure 8 As shown, the movable support 32 includes a base 321 and a boss 322 connected to each other. A positioning protrusion 3221 is disposed on the side wall of the boss 322. The fixed support 31 is provided with an installation channel 311. One end of the installation channel 311 is connected to the water outlet channel 100 through a connecting port 313, and the other end is connected to the water outlet 3151. The base 321 is fitted into the installation channel 311, and the boss 322 is confined within the connecting port 313. The above arrangement avoids mutual interference between the fitting position and the positioning position of the movable support 32, so that the movable support 32 can be accurately positioned and installed on the fixed support 31.

[0061] In this embodiment, as Figure 3 and Figure 5 As shown, the fixed support 31 is snapped onto the inner side of one end of the exhaust pipe 2, and multiple mounting protrusions 3211 are provided on the side wall of the base 321. The positioning groove 314 is provided on the inner wall of the connecting port 313 and is provided through the axis of the connecting port 313. The positioning protrusion 3221 is provided on one side of the outer wall of the boss 322, and the exhaust pipe 2 is fixed to the boss 322.

[0062] Specifically, the water outlet 3151 is located on the fixed support 31. This arrangement makes the water outlet position of the water outlet device more fixed and reliable.

[0063] More specifically, the mixing channel 300 is disposed on the movable support 32. The above arrangement allows the mixing channel 300 to move with the exhaust pipe 2, making it more suitable for the exhaust operation of the exhaust pipe 2.

[0064] More specifically, such as Figure 3 and Figure 6 As shown, the movable support 32 is equipped with an exhaust port 323 and a drain port 324. The exhaust channel 200 is connected to the mixing channel 300 through the exhaust port 323, and the water outlet channel 100 is connected to the mixing channel 300 through the drain port 324. The above arrangement makes the relative positions of the exhaust port 323 and the drain port 324 more precise, ensuring the reliability of the exhaust operation.

[0065] In this embodiment, the mixing channel 300 is disposed on the base 321, and the exhaust port 323 is disposed on the side of the boss 322 away from the base 321, so that the exhaust pipe 2 is fixed to the side of the boss 322 away from the base 321, and the drain port 324 and the boss 322 are disposed on the same side of the base 321.

[0066] Specifically, such as Figure 4 and Figure 5 As shown, the water outlet device also includes a water outlet component 4. A water outlet groove 315 is provided on the fixed support 31, and the water outlet channel 100 is connected to the water outlet groove 315. The groove opening of the water outlet groove 315 is the water outlet 3151, and the water outlet component 4 is assembled in the water outlet groove 315. The above arrangement allows the water outlet component 4 to be integrated and installed on the fixed support 31, improving the utilization efficiency of the fixed support 31.

[0067] More specifically, the installation channel 311 is located at the bottom of the water outlet trough 315, the water outlet trough 315 is connected to one end of the installation channel 311, and the other end of the installation channel 311 is connected to the water outlet channel 100 through the connecting port 313. The fixed support 31 extends into the water outlet channel 100 and is fixed to one end of the water outlet pipe 1. The opening of the water outlet trough 315 is flush with the port of one end of the water outlet pipe 1. The cross-sectional area of ​​the water outlet trough 315 is larger than the cross-sectional area of ​​the installation channel 311, and the cross-sectional area of ​​the installation channel 311 is larger than the cross-sectional area of ​​the connecting port 313.

[0068] In this embodiment, the inner wall of the water outlet tank 315 is provided with internal threads, and the water outlet component 4 is screwed into the water outlet tank 315. The water outlet component 4 is an aerator component or a shower head component, both of which are conventional devices in the art, and their structure and working principle will not be described in detail here.

[0069] Specifically, such as Figure 8As shown, the outer wall of the exhaust pipe 2 is provided with multiple protruding ribs 21. The length direction of the protruding ribs 21 is set at an angle to the extension direction of the exhaust pipe 2. The multiple protruding ribs 21 are parallel to each other and are arranged at equal intervals in the extension direction of the exhaust pipe 2. By setting the protruding ribs 21, the structural strength of the exhaust pipe 2 is improved, and the exhaust pipe 2 can also be cut with the protruding ribs 21 as a reference, so that the exhaust pipe 2 can be adapted to different types of water outlet pipes 1.

[0070] More specifically, in the water outlet channel 100, the vent pipe 2 is bent, and the plane containing the axis of the vent pipe 2 is the intermediate plane. Two sets of protruding ribs 21 are provided, located on both sides of the intermediate plane. The multiple protruding ribs 21 in each set are parallel to each other and arranged at equal intervals in the extension direction of the vent pipe 2. This arrangement increases the structural strength of the vent pipe 2 without increasing the difficulty of bending it, and the protruding ribs 21 on both sides can also play a role in coarse positioning, indicating the insertion orientation of the vent pipe 2 in the water outlet pipe 1.

[0071] More specifically, the vent pipe 2 is a flexible hose. The distance between the top of the outlet pipe 1 and the outlet 3151 in the vertical direction is H, and the length of the vent pipe 2 in its free state is equal to H. This configuration facilitates the installation and adaptation of the vent pipe 2.

[0072] In this embodiment, the exhaust pipe 2 is a flexible hose that can be adapted to... Figure 9 , Figure 10 and Figure 11 And other leading companies, with Figure 11 Taking the faucet shown as an example, refer to Figure 12 As shown, in the initial state, as indicated by the vent pipe 2 and movable support 32 on the left, align the bottom end of the vent pipe 2 with the water outlet 3151 according to the marked lines. Make a beveled cut at the top of the water outlet pipe 1, using the corresponding protruding ridge 21 as the reference. After cutting, as shown by the vent pipe 2 and movable support 32 on the right, insert the vent pipe 2 into the water outlet pipe 1 and install the movable support 32 onto the fixed support 31. This will allow the top opening of the vent pipe 2 to connect to the air storage area 102. Vents with different shaped curved arms can all have their vent pipe 2 cut using the above alignment method. The vent pipe 2 has its own cutting reference marking lines, i.e., the protruding ridge 21. Simply cut directly within the marking lines to obtain the required length of the vent pipe 2. Therefore, this improves the versatility, economy, and convenience of the vent pipe 2.

[0073] In the water outlet device of the present invention, the water outlet pipe 1 can retain the aesthetics and integrity of the original water outlet pipe 1 by embedding the exhaust pipe 2 inside the mounting base 3, without the need to add an external auxiliary structure. The exhaust pipe 2 has a protruding ridge 21 as a cutting reference scale line. The exhaust pipe 2 can be freely cut according to the curved arm shape of the water outlet pipe 1, so the length can be adjusted, realizing the practicality of one pipe for multiple uses, and greatly reducing the investment cost of molds.

[0074] Example 2

[0075] like Figures 13 to 16 As shown, this embodiment provides a water outlet device, and its components that are the same as or corresponding to those in Embodiment 1 are referred to using the same or corresponding reference numerals as those in Embodiment 1. For simplicity, only the differences between this embodiment and Embodiment 1 will be described below.

[0076] The difference between the water outlet device in this embodiment and that in Embodiment 1 is that the fixed support 31 is screwed onto the outside of one end of the water outlet pipe 1. This arrangement facilitates the disassembly and maintenance of the fixed support 31 and the water outlet pipe 1.

[0077] Specifically, such as Figure 15 As shown, the outer wall of one end of the water outlet pipe 1 is provided with an external threaded portion 103, such as... Figure 16 As shown, the fixed support 31 is provided with a connecting groove 316 at one end facing the water outlet pipe 1. The inner wall of the connecting groove 316 is provided with an internal thread, which is screwed to the external thread 103.

[0078] In this embodiment, the water outlet groove 315 and the connecting groove 316 are located at both ends of the fixed support 31 along the axial direction.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
