Description

Technical Field

[0001] This utility model relates to the field of bathroom water outlet structure technology, and in particular to a water outlet device. Background Technology

[0002] To avoid impacting the overall appearance of external aerators and other water outlet devices on the bathroom fixtures, current bathroom products often employ an embedded installation method, embedding the water outlet device inside the water outlet of the fixture, as shown in the aerator structure disclosed in announcement number CN221236128U. While this solution achieves the internal installation of aerators and other water outlet devices, it also makes it difficult to install conventional water-saving plates to limit the water flow, thus failing to meet national water efficiency standards. This is because installing conventional water-saving plates would restrict the rotation of the water outlet panel; if more space were allocated to allow for the rotation of the water outlet panel, it would be no different from other external structures and could not be embedded into the water outlet of the fixture. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water outlet device that can limit the water flow rate to meet the national water efficiency standards while also allowing for embedded installation at the outlet of the water outlet device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a water outlet device having an assembly ring embedded in the water outlet end of the water outlet device, and a water outlet panel flipped and disposed within the assembly ring, including a flow limiting part disposed on the assembly ring, the top of the flow limiting part extending into the water outlet pipe of the water outlet device, the flow limiting part having a flow limiting hole, and the water outlet surface of the flow limiting part and the inner wall of the assembly ring enclosing a flipping space for the water outlet panel to flip.

[0006] Furthermore, the flow limiting part is provided with a plurality of flow limiting holes, which are symmetrically distributed on the flow limiting part.

[0007] Furthermore, the inner wall of the flow-limiting part is an arc-shaped surface.

[0011] Furthermore, the aforementioned water outlet device also includes a second sealing ring, and a third limiting part is provided on one end face of the assembly ring facing the water outlet panel.

[0019] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Please refer to Figures 1 to 4 As shown, the water outlet device is installed inside the water outlet of the water outlet device 6 via the assembly ring 1; the water outlet panel 2 is flipped and installed on the assembly ring 1, and the water outlet surface is switched by flipping the water outlet panel 2 to achieve different water spray discharge; a flow limiting part 3 is added to the assembly ring 1, and the top of the flow limiting part 3 extends into the water outlet pipe 61 of the water outlet device 6. By utilizing the space in the water outlet pipe 61, the flow limiting part 3 is prevented from affecting the flipping of the water outlet panel 2. At the same time, the flow limiting hole 31 on the flow limiting part 3 can limit the flow rate of water flowing to the water outlet panel 2, thereby making the water outlet flow rate of the water outlet device meet the requirements.

[0021] Please refer to Figures 1 to 4 As shown, the present invention provides a water outlet device, which has an assembly ring 1 embedded in the water outlet end of a water outlet device 6, and a water outlet panel 2 flipped and disposed in the assembly ring 1. A flow limiting part 3 is provided on the assembly ring 1, the top of the flow limiting part 3 extends into the water outlet pipe 61 of the water outlet device 6, and a flow limiting hole 31 is provided on the flow limiting part 3. The water outlet surface of the flow limiting part 3 and the inner wall of the assembly ring 1 enclose a flipping space for the water outlet panel 2 to flip.

[0022] Working principle: A flow-limiting part 3 is added to the assembly ring 1, and the top of the flow-limiting part 3 extends into the water outlet pipe 61 of the water outlet device 6. By utilizing the space in the water outlet pipe 61, it is ensured that the water outlet surface of the flow-limiting part 3 can be enclosed with the inner wall of the assembly ring 1 to form a flipping space for the water outlet panel 2 to flip. At the same time, the flow-limiting hole 31 on the flow-limiting part 3 can limit the flow rate of water entering the flipping space, thereby ensuring that the water outlet flow rate of the water outlet device meets the requirements.

[0023] It is worth noting that the flow restrictor 3 should remain rigid under a water flow pressure of 125 psi to avoid flow deviation caused by deformation of the flow restrictor 31. Preferably, the flow restrictor 3 is made of plastic materials such as polyoxymethylene, reinforced nylon, or polycarbonate.

[0024] In some embodiments, the water-facing surface of the flow-limiting part 3 is divided into a first region and a second region. The first region is located on the top surface of the flow-limiting part 3 near the pipe wall of the outlet pipe 61, and the second region has a flow-limiting hole 31, located outside the first region. Since the flow-limiting part 3 partially extends into the outlet pipe 61, there is a situation where the flow-limiting part 3 abuts against the inner wall of the outlet pipe 61. If a flow-limiting hole 31 is provided at this location, it will cause water flow to have difficulty passing through the flow-limiting part 3, thereby causing flow deviation.

[0025] Specifically, taking the water-facing surface of the flow-limiting part 3 as an example, the first region is the highest point of the flow-limiting part 3, and the second region surrounds the first region.

[0026] It is worth noting that the projection of the first area onto the water outlet panel 2 is circular or rectangular, and of course, it can also be other polygonal shapes.

[0027] In some implementations, please refer to Figure 5 As shown, multiple flow-limiting holes 31 are provided on the flow-limiting part 3, and the flow-limiting holes 31 are symmetrically distributed on the flow-limiting part 3. The symmetrical distribution of multiple flow-limiting holes 31 on the flow-limiting part 3 can ensure the stability of the water flow through the flow-limiting part 3, and ensure that the force on each part of the flow-limiting part 3 is as uniform as possible. This avoids deformation of the flow-limiting holes 31 caused by excessive water pressure at a certain part of the flow-limiting part 3, which would prevent the flow-limiting holes 31 from being unable to limit the water flow according to the set flow rate.

[0028] The flow-limiting holes 31 can be arranged in a ring along the water-facing surface contour of the flow-limiting section 3, or they can be arranged in multiple rings along the water-facing surface contour of the flow-limiting section 3.

[0029] In some embodiments, the more uniformly arranged flow-limiting holes 31 there are, the more uniform the water flow into the water outlet panel 2 will be, and the more stable the flow rate of the water discharged from the water outlet panel 2 will be. Under the condition that the total water flow area at the inlet end of the flow-limiting holes 31 needs to be controlled to meet the final discharge flow rate, if the number of flow-limiting holes 31 is increased, the water flow area of ​​a single flow-limiting hole 31 must be reduced. Reducing the water flow area of ​​a single flow-limiting hole 31 can easily lead to the flow-limiting hole 31 being blocked by impurities. Conversely, if a larger flow-limiting hole 31 is to be set to avoid being blocked by impurities, the total number of flow-limiting holes 31 must be reduced. Fewer flow-limiting holes 31 will reduce the uniformity of the water flow entering the water outlet panel 2. In response, under the current flow restriction conditions, a better solution is shown in the attached figure: 20 flow restriction holes 31 are set on the flow restriction part 3, and the flow restriction holes 31 are evenly arranged in two circles along the water-facing surface contour of the flow restriction part 3. This can ensure that the straight-line interval between all the flow restriction holes 31 is greater than 2mm. The diameter of the inlet end of a single flow restriction hole 31 is 0.7mm. This solution can well balance the uniformity of the water flow entering the outlet panel 2 and the possibility of the flow restriction holes 31 being blocked by impurities.

[0030] In some implementations, the total area of ​​the inlet end of all flow restrictors 31 is less than 8 mm². 2 The total area of ​​the inlet end of the flow limiting orifice 31 is limited to ensure that the water flow rate of the outlet device meets the requirements of the national water efficiency standard.

[0031] It is worth noting that the total inlet area of ​​the flow restrictor 31 is 4mm. 2 Up to 7.5mm 2 Preferably, the total inlet area of ​​the flow restrictor 31 is 6.5 mm. 2 Up to 7.1mm 2 .

[0032] The total inlet area of ​​the flow restrictor 31 includes, but is not limited to, 4mm. 2 4.5mm 2 5mm 2 5.5mm 2 6mm 2 6.5mm 2 7mm 2 7.5mm 2 8mm 2 .

[0033] In some embodiments, a flow-limiting hole 31 is provided on the flow-limiting part 3.

[0034] In some embodiments, the inner wall of the flow restrictor 3 is set as an arc-shaped surface so that the flipping trajectory of the water outlet panel 2 during the flipping process can fit as closely as possible to the inner wall contour of the flow restrictor 3, thereby reducing the amount of external space occupied by the flow restrictor 3.

[0035] In some embodiments, the water-facing surface of the flow-limiting part 3 is arc-shaped or convex, so that the water-facing surface of the flow-limiting part 3 can extend into the water outlet pipe 61 as much as possible, and the space of the water outlet pipe 61 is used to provide the water outlet panel 2 with a flipping space.

[0036] It is worth noting that the water-facing surface of the limiting flow section 3 can also be cone-shaped.

[0037] The specific shape of the flow limiting part 3 needs to be adapted to the outlet structure of the water outlet device 6 to avoid the inner wall of the outlet of the water outlet device 6 covering the flow limiting hole 31.

[0038] In some embodiments, by limiting the inlet area of ​​the flow restrictor 31 to be smaller than the outlet area, the water flow velocity can be slowed down as the water flow area gradually increases after entering the flow restrictor 31.

[0039] In some implementations, please refer to Figure 1 and Figure 6 As shown, the water outlet device also includes a first sealing ring 4. A first limiting part 11 is provided at the top of the assembly ring 1, and a second limiting part 32 is provided on the water-facing surface of the flow-limiting part 3. The first limiting part 11 and the second limiting part 32 enclose each other to form a first sealing groove, and the first sealing ring 4 is disposed within the first sealing groove. By forming the first sealing groove through the enclosed first limiting part 11 and the second limiting part 32, the first sealing ring 4 can seal above the gap between the assembly ring 1 and the flow-limiting part 3, thus preventing water from flowing out from the gap between the assembly ring 1 and the flow-limiting part 3.

[0040] In some implementations, please refer to Figure 6 As shown, the first sealing ring 4 has a first mating part 41 on the side facing the second limiting part 32, and the second limiting part 32 has a second mating part 321 on the side facing the first sealing ring 4. The first mating part 41 and the second mating part 321 are interlocked. By utilizing the cooperation between the first mating part 41 and the second mating part 321, the first sealing ring 4 is further fixed in the first sealing groove.

[0041] Specifically, when the first mating part 41 is concave, the second mating part 321 is convex; when the first mating part 41 is convex, the second mating part 321 is concave. The convex part can be annular, or it can be a plurality of protrusions arranged circumferentially along the contour of the second limiting part 32.

[0042] It is worth noting that the second mating part 321 can be provided on the second limiting part 32 or on the first limiting part 11.

[0043] In some implementations, please refer to Figure 1 and Figure 7As shown, the water outlet device also includes a second sealing ring 5. A third limiting part 12 is provided on one end face of the assembly ring 1 facing the water outlet panel 2. The third limiting part 12, together with the side wall of the assembly ring 1 and the water outlet panel 2, forms a second sealing groove, and the second sealing ring 5 is disposed in the second sealing groove. The second sealing ring 5 is supported by the third limiting part 12 so that the second sealing ring 5 can seal between the assembly ring 1 and the water outlet panel 2 to prevent water from flowing out from the gap between the assembly ring 1 and the water outlet panel 2.

[0044] In some implementations, please refer to Figure 7 As shown, the outlet surface of the flow-limiting part 3 is provided with a pressing part 33, which abuts against the side of the second sealing ring 5 near the outlet panel 2. After the water outlet device is embedded into the outlet of the water outlet device 6, the flow-limiting part 3 will be squeezed by components such as the water outlet device 6 and the assembly ring 1, so that the flow-limiting part 3 will move towards the outlet panel 2. In turn, the pressing part 33 will squeeze the second sealing ring 5 to deform, thereby improving the sealing effect of the second sealing ring 5 and preventing the second sealing ring 5 from falling out of the second sealing groove.

[0045] In some implementations, please refer to Figure 3 and Figure 8 As shown, the outer wall of the assembly ring 1 is provided with an external thread 13, and the outlet of the water outlet device 6 is provided with an internal thread that matches the external thread 13. Through the threaded connection, the installation of the water outlet device on the water outlet device 6 can be completed quickly.

[0046] In some implementations, please refer to Figure 8 As shown, the bottom surface of the assembly ring 1 has multiple grooves 14 arranged circumferentially. To facilitate the connection between the water outlet device and the water outlet equipment 6, the grooves 14 on the bottom surface of the assembly ring 1 can act as wrench positions, allowing for easy assembly and disassembly of the water outlet device and the water outlet equipment 6 using external tools. Preferably, 4 to 8 grooves 14 are evenly spaced and symmetrically arranged.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
