Description

Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to a toilet spray nozzle and a toilet. Background Technology

[0002] In existing technologies, jet siphon toilets have been widely used in residential and public bathrooms due to their efficient flushing and water-saving performance. However, these toilets generally suffer from a significant technical drawback in actual use: excessive noise during flushing, which seriously affects the user experience.

[0003] In-depth analysis revealed that the aforementioned noise problem primarily stemmed from excessively high water pressure in the flushing system. This caused the water to impact the toilet bowl's inner wall and the sewage pipe inlet at high speed, triggering severe fluid vibration and sound radiation. Particularly during the siphon failure phase, the water flow at the jet nozzle still possessed high kinetic energy, resulting in "excess kinetic energy." At this stage, maintaining a strong flushing force was no longer necessary; however, the continuous impact of the high-speed water flow exacerbated fluid disturbance and noise generation, becoming the primary noise source during this phase. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a toilet spray nozzle and a toilet. By optimizing the structure of the spray nozzle, it effectively reduces flushing noise and significantly improves the user experience.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a toilet spray nozzle, including a nozzle, one end of which is provided with a water inlet; the nozzle is provided with a main water channel and a secondary water channel that are independent of each other and are both connected to the water inlet; the other end of the nozzle is provided with a main water outlet connected to the main water channel and a secondary water outlet connected to the secondary water channel; the secondary water channel is provided with a pressure relief component, which automatically opens when the water pressure at the water inlet exceeds a preset threshold, so that part of the water flows through the secondary water channel and is discharged from the secondary water outlet.

[0006] In a preferred embodiment, the secondary water outlet is located above the main water outlet. The secondary water outlet has a fan-shaped structure, and its outlet end is a horizontally extending long strip slit, so that when water is discharged from the secondary water outlet, a fan-shaped sheet of water is output. This fan-shaped sheet of water forms a sound-insulating water film covering the sewage pipe inlet of the toilet.

[0007] In a preferred embodiment, the secondary outlet is inclined upward at least on its upper wall surface, so that when water is discharged from the secondary outlet, it outputs an upwardly inclined fan-shaped sheet of water.

[0008] In a preferred embodiment, the pressure relief assembly includes a sliding plug and a reset member. The sliding plug is slidably disposed within the secondary water channel along the extension direction of the secondary water channel, and the reset member is provided between the sliding plug and the nozzle to provide a reset force to the sliding plug. When the water pressure at the inlet exceeds a preset threshold, the water flow acts on the sliding plug, causing the sliding plug to slide along the water flow direction against the reset force, thereby opening the secondary water channel.

[0009] In a preferred embodiment, the reset member includes an elastic member that abuts against the first limiting portion of the sliding plug and the second limiting portion of the inner wall of the secondary water channel, and the elastic member is in a pre-compressed state in its natural state; the second limiting portion is located on the side of the sliding plug away from the water inlet.

[0010] In a preferred embodiment, the elastic element is a spring; the first limiting portion and the second limiting portion are respectively limiting step surfaces.

[0011] In a preferred embodiment, the secondary water channel is provided with a sealing step surface that is annular and opposite to the water inlet. The sliding plug is provided with a sealing part, and when the sliding plug is in the reset state, the sealing part abuts against the sealing step surface.

[0012] In a preferred embodiment, the sealing step surface is a conical surface with a diameter that gradually increases along the water flow direction; the sealing part is a sealing ring, which is fitted onto the limiting groove provided on the outer wall surface of the sliding plug.

[0013] In a preferred embodiment, the port of the main waterway outlet and / or the perimeter of the main water outlet are arc-shaped, with both ends of the arc-shaped structure extending upwards.

[0014] In a preferred embodiment, the nozzle includes a nozzle body and a secondary water channel body installed within the nozzle body. The nozzle body has the inlet, the main outlet, and the secondary outlet. The secondary water channel body has the secondary water channel and a portion of the main water channel that cooperates with the main outlet. The outer wall of the secondary water channel body and the inner wall of the nozzle body together form the remaining portion of the main water channel. The secondary water channel body includes at least two sections that are sequentially sealed and connected along the water flow direction, and each section forms a portion of the secondary water channel in the water flow direction.

[0015] This utility model also provides a toilet, including a toilet body, which has a commode bowl and a sewage pipe, the inlet of which is connected to the bottom of the commode bowl; the bottom of the commode bowl is equipped with a spray nozzle as described in this utility model, and the main water outlet and the auxiliary water outlet are both arranged facing the inlet of the sewage pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model features an independent main water channel and a secondary water channel inside the nozzle. The secondary water channel contains a pressure relief component, which automatically opens when the inlet water pressure exceeds a preset threshold, allowing some water to flow through the secondary water channel for pressure relief. This structure not only effectively reduces flushing pressure and avoids excessive flushing noise during the initial flushing stage when water pressure is too high, but also allows for the orderly release and dissipation of excess flushing kinetic energy during the siphon breakdown stage. This significantly suppresses violent collisions between water flow and the toilet bowl wall, sewage pipe inlet, and other structures, thereby effectively reducing noise generated during the siphon breakdown stage and enabling low-noise flushing.

[0018] 2. As a preferred option, the secondary water outlet is a horizontally extending narrow slit. The sheet-like water flow it outputs forms a sound-insulating water film covering the sewage pipe inlet of the toilet. This film can effectively buffer and absorb the energy of the high-speed impact water flow during flushing, especially during the siphon breakdown stage. At the same time, the sound-insulating water film forms a covering layer in space, effectively shielding the noise radiation area, constructing a local acoustic barrier, and further suppressing the propagation of sound waves.

[0019] 3. As a preferred embodiment, the pressure relief assembly includes a sliding plug and a reset component. The sliding plug is slidably disposed within the secondary water channel, and a reset component is provided between the sliding plug and the nozzle to provide a reset force to the sliding plug. When the inlet water pressure exceeds a preset threshold, the water flow acts on the sliding plug, causing it to slide along the water flow direction, thereby opening the secondary water channel. This design of the present invention makes the pressure relief assembly structurally simple, responsive, requires no external power, is easy to process and assemble, and has good manufacturability.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the present invention is not limited to the embodiments of the present invention. Attached Figure Description

[0036] In this utility model, the terms "first," "second," etc., are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "inner," and "outer" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and is solely for the convenience of describing this utility model, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] Furthermore, in the description of this utility model, "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] Please see Figures 1-8 As shown, this utility model discloses a toilet spray nozzle, including a nozzle with a water inlet 11 at one end. The nozzle contains a main water channel 14 and a secondary water channel 23, both independent and connected to the water inlet 11. The other end of the nozzle has a main outlet 12 connected to the main water channel 14 and a secondary outlet 13 connected to the secondary water channel 23. A pressure relief component is installed in the secondary water channel 23. This component automatically opens when the inlet pressure at the water inlet 11 exceeds a preset threshold, allowing some water to flow through the secondary water channel 23 and be discharged from the secondary outlet 13. This orderly release and dissipation of excess flushing kinetic energy reduces toilet flushing noise. The "one end" and "the other end" of the nozzle refer to the two opposite ends of the nozzle in the axial direction.

[0039] In a preferred embodiment, the secondary outlet 13 is located above the main outlet 12, and its overall outline is fan-shaped, with its outlet end being a horizontally extending elongated slit. This allows the secondary outlet 13 to output a fan-shaped sheet of water 7, which can cover the sewage pipe inlet area of ​​the toilet, forming a continuous sound-insulating water film. This creates a local acoustic barrier, suppressing the propagation of flushing noise and further reducing flushing noise. Furthermore, the secondary outlet 13 is inclined upwards at least on its upper wall, so that when it outputs water, it outputs an upwardly inclined fan-shaped sheet of water 7, thereby expanding its coverage area and achieving full coverage of the sewage pipe inlet area, improving the integrity of the sound-insulating water film and the noise reduction effect.

[0040] As a preferred embodiment, the outlet end of the main waterway 14 and / or the periphery of the main outlet 12 are arc-shaped structures. The two ends of the arc-shaped structure extend upward to form an upward-opening arc-shaped outlet to output an arc-shaped water flow. The trajectory of the arc-shaped water flow is adapted to the curvature of the inner wall of the toilet's sewage pipe, which can evenly cover the inlet area of ​​the sewage pipe along the circumference of the inner wall, achieving efficient flushing and cleaning of the inlet area, effectively improving sewage discharge efficiency and reducing the risk of residue.

[0041] like Figure 1 , Figure 5 As shown, the pressure relief assembly includes a sliding plug 3 and a reset member. The sliding plug 3 is slidably disposed within the secondary water channel 23 along its extension direction, and a reset member is provided between the sliding plug 3 and the nozzle to provide a reset force to the sliding plug 3. When the water pressure at the inlet 11 exceeds a preset threshold, the water flow acts on the sliding plug 3, causing it to slide against the reset force along the water flow direction, thereby opening the secondary water channel 23. This design of the present invention makes the pressure relief assembly simple in structure, highly responsive, requires no external power, and is easy to process and assemble.

[0042] Preferably, the reset element includes an elastic element that abuts against the first limiting part 31 of the sliding plug 3 and the second limiting part 211 of the inner wall of the secondary water channel 23; the second limiting part 211 is located on the side of the sliding plug 3 away from the inlet 11. In this embodiment, the elastic element is exemplified by a spring 4, but it is not limited to a spring 4, and other elements with elastic restoring force (such as rubber parts, leaf springs, etc.) can also be used. The elastic element (i.e., spring 4 in this embodiment) is in a pre-compressed state in its natural state, thereby applying a pre-pressure to the sliding plug 3 in the direction of closing the secondary water channel 23, so that it always maintains the reset state of closing the secondary water channel 23 when no external force is applied. The first limiting part 31 and the second limiting part 211 are both limiting stepped surfaces, and the two ends of the spring 4 abut against the first limiting part 31 and the second limiting part 211, respectively.

[0043] like Figure 5 , Figure 7As shown, the secondary waterway 23 has an annular sealing step surface 221 facing away from the inlet 11. The sliding plug 3 has a sealing part, which abuts against the sealing step surface 221 when the sliding plug 3 is in the reset state. Furthermore, the sealing step surface 221 is a conical surface with a diameter that gradually increases along the water flow direction. This allows the contact area between the sealing part and the sealing step surface 221 to gradually increase as the sliding plug 3 slides in the direction of closing the secondary waterway 23, thus improving the tightness of the fit and significantly enhancing the closing effect on the secondary waterway 23. The sealing part is preferably a sealing ring 5 fitted around the outer circumference of the sliding plug 3. The sliding plug 3 has a corresponding limiting groove 32 for axial positioning and constraint of the sealing ring 5, preventing it from shifting or falling off during sliding. The sealing step surface 221 is located near the inlet end of the secondary waterway 23, allowing the sliding plug 3 to move axially as quickly as possible when water pressure exceeds a preset threshold when water enters the secondary waterway 23.

[0044] like Figure 1 As shown, the nozzle includes a nozzle body 1 and a secondary water channel body 2 installed within the nozzle body 1. The nozzle body 1 has an inlet 11, a main outlet 12, and a secondary outlet 13. The secondary water channel body 2 has a secondary water channel 23 and a portion of a main water channel 14 that cooperates with the main outlet 12 (named the first portion 141). The outer wall of the secondary water channel body 2 and the inner wall of the nozzle body 1 together form the remaining portion of the main water channel 14 (named the second portion 142). In this embodiment, the first portion 141 of the main water channel 14 passes through the main outlet 12, and its cross-section is arc-shaped.

[0045] Preferably, the secondary waterway body 2 includes at least two sections that are sequentially and sealed together along the water flow direction, each section forming a portion of the secondary waterway 23 in the water flow direction. In this embodiment, the secondary waterway body 2 includes two sections that are sealed together along the water flow direction, but is not limited thereto. These two sections are respectively named the first pipe section 21 and the second pipe section 22. The adjacent ends of the first pipe section 21 and the second pipe section 22 are connected by a sealed sleeve connection to achieve the sealing type and structural stability of the overall waterway. The first part 141 is provided in the first pipe section 21, the first limiting part 31 is provided in the first pipe section 21, and the sealing step surface 221 is provided in the second pipe section 22. The secondary waterway body 2, with its segmented structural design, allows each functional component to be processed and assembled separately, effectively reducing the overall processing difficulty and improving manufacturing efficiency. At the same time, it significantly improves the convenience of installing and replacing the pressure relief components.

[0046] This utility model discloses a toilet spray nozzle, which can be applied to smart toilets, but is not limited thereto. In application, it is installed at the bottom of the toilet bowl 81 of the toilet body 8, with both the main outlet 12 and the auxiliary outlet 13 facing the inlet of the sewage pipe 82 of the toilet body 8. Figure 11 , Figure 12 As shown.

[0047] The working principle of this utility model is as follows:

[0048] When the inlet pressure of inlet 11 does not exceed the preset threshold, the secondary water channel 23 remains closed, only the main water channel 14 is open, and water flows out of the main outlet 12, forming the main jet water flow 6 (e.g. Figure 6 As shown), it is used to push the waste in the toilet water seal into the drain pipe 82 and to help establish and maintain the siphon effect. When the inlet water pressure of the inlet 11 exceeds the preset threshold, part of the water flows out through the main water channel 14 to form the main jet water flow 6, while the remaining water flow acts on the sliding stopper 3, driving the sliding stopper 3 to overcome the elastic force of the spring 4 and slide along the water flow direction, thereby opening the secondary water channel 23, so that water comes out of the secondary outlet 13 and sprays out a slightly upward-sloping fan-shaped sheet water flow 7 (as shown). Figure 7 , Figure 8 As shown), the fan-shaped sheet of water 7 forms a sound-insulating water film covering the drain pipe inlet of the toilet, such as... Figure 13 , Figure 14 As shown.

[0049] Therefore, this invention not only relieves excessive water pressure during the initial flushing stage by using the secondary water channel 23 and pressure relief components, effectively reducing flushing pressure and avoiding flushing noise caused by excessive water pressure; but also, during the siphon breakdown stage, it orderly releases and dissipates excess flushing kinetic energy, significantly suppressing violent collisions between the water flow and the inner wall of the toilet bowl 81, the inlet of the sewage pipe 82, and other structures, thereby effectively reducing the noise generated during the siphon breakdown stage and enabling the toilet to achieve low-noise flushing. In particular, when the secondary water channel 23 is open, the fan-shaped sheet-like water flow 7 output from the secondary outlet 13 forms a sound-insulating water film covering the sewage pipe inlet of the toilet. This film effectively buffers and absorbs the energy of the high-speed impact water flow during flushing, especially during the siphon breakdown stage. At the same time, the sound-insulating water film forms a covering layer in space, effectively shielding the noise radiation area, constructing a local acoustic barrier, and further suppressing sound wave propagation.

[0050] Please see Figures 1-14 As shown, a toilet of this utility model includes a toilet body 8 and a spray nozzle 9. The toilet body 8 is provided with a toilet bowl 81 and a sewage pipe 82. The inlet of the sewage pipe 82 is connected to the bottom of the toilet bowl 81. The spray nozzle 9 is installed at the bottom of the toilet bowl 81. The spray nozzle 9 is implemented using the spray nozzle of the toilet of this utility model. Its main water outlet 12 and auxiliary water outlet 13 are both set towards the inlet of the sewage pipe 82.

[0051] The toilet of this invention is specifically a smart toilet, but is not limited to this. It uses a water pump to deliver and pressurize the water flow; that is, the outlet of the water pump is connected to the inlet 11 of the spray nozzle 9, forming a high-pressure water supply path. By adjusting the duty cycle of the water pump, this invention can dynamically control the water output frequency and pressure, thereby optimizing the pulse characteristics of the spray flow and improving the siphon formation efficiency and flushing effect. At the same time, combined with the structural design of the spray nozzle of this invention, it can effectively reduce water flow impact noise.

[0052] For details on the structure and working principle of the toilet spray nozzle, please refer to the previous description section; it will not be repeated here.

[0053] The present invention relates to a toilet spray nozzle and a toilet, and the parts not described herein are the same as or can be implemented using existing technology.
