Description
Technical Field
[0001] This utility model relates to the field of sanitary ware technology, and in particular to a silent toilet nozzle and a quiet toilet. Background Technology
[0002] As people's living standards improve, higher demands are being placed on the comfort and quietness of smart toilets. A common problem with smart toilets on the market is excessive flushing noise, largely due to the water jet from the toilet nozzle. Existing toilet nozzles typically spray water in a scattered manner, meaning the water spreads outwards, creating splashes. These splashes repeatedly impact the ceramic inner wall, the water surface, or other parts of the toilet, generating high-intensity impact noise. The faster the water flow, the greater the impact noise, significantly increasing the overall noise level during flushing and severely impacting the user experience. This not only disturbs the indoor environment but also contradicts the modern pursuit of a quiet home. Therefore, developing a toilet nozzle and matching toilet that can effectively reduce flushing noise while maintaining washing performance has become an urgent technical challenge. Utility Model Content

[0012] The nozzle body has a limiting mounting groove on the side near the nozzle. The fixing member is connected to the nozzle body. The fixing member has a snap-fit hole on the side away from the nozzle body. The size of the snap-fit hole is smaller than the size of the connecting part. The side of the connecting part away from the spray part is installed in the limiting mounting groove. The other side of the connecting part passes through the snap-fit hole and protrudes from the outside of the fixing member.
[0013] As an improvement to the above technical solution, the fixing member is hollow on the side near the nozzle body to form a mounting groove for connecting the nozzle body. The inner wall of the mounting groove is provided with an internal thread, and the outer wall of the nozzle body near the fixing member is provided with an external thread. The side of the nozzle body near the fixing member is installed in the mounting groove, and the fixing member and the nozzle body are threadedly connected by the cooperation of the internal thread and the external thread.
[0014] As an improvement to the above technical solution, the connecting part is shaped like a ball table, and the side of the connecting part used to connect with the nozzle body is the first connecting part. The shape and size of the limiting mounting groove are respectively adapted to the shape and size of the first connecting part.
[0015] Accordingly, this utility model also provides a silent toilet, including a toilet body, a toilet bowl, a siphon pipe and the above-mentioned silent toilet nozzle, wherein the toilet bowl, the siphon pipe and the silent toilet nozzle are all installed inside the toilet body;
[0016] The toilet bowl includes a toilet bowl body and a water flow guide located on the top outer periphery of the toilet bowl body. The silent toilet nozzle is installed on one side of the water flow guide, and the outlet of the silent toilet nozzle faces the front end of the water flow guide.
[0017] The toilet bowl body is provided with a drain outlet at the bottom, and the siphon pipe is provided with a siphon inlet. The drain outlet and the siphon inlet are connected.
[0018] As an improvement to the above technical solution, the water flow guide protrudes from the periphery of the toilet bowl body. The water flow guide includes a water flow guide platform and a raised periphery surrounding the outer periphery of the water flow guide platform. The inner periphery of the water flow guide platform is connected to the top of the toilet bowl body. A water flow guide groove is formed between the surface of the water flow guide platform and the inner wall of the raised periphery. The jetting part is located in the water flow guide groove, and gaps are provided between the jetting part and the raised periphery, as well as between the jetting part and the water flow guide platform.
[0019] The connection between the raised edging and the water flow guiding platform is smoothly transitioned, and the connection between the water flow guiding platform and the toilet body is also smoothly transitioned.

[0024] Implementing this utility model has the following beneficial effects:
[0025] The nozzle structure is improved so that the diameter of the spray section is smaller than its length, creating a laminar flow design for the silent toilet nozzle. This means the water flows in a laminar flow pattern within the spray section, forming a jet of water instead of scattering in all directions. This significantly reduces the impact noise generated by the high-intensity impact of scattered water droplets on the ceramic inner wall and water surface, achieving a noise reduction effect. Furthermore, due to the laminar flow design, the water jet has a higher central velocity, increasing the fluid range and ensuring the water reaches the front of the toilet bowl for effective flushing.
[0026] Furthermore, by controlling the flow cross-sectional area of the injection section to 63mm 2 ~154mm 2This design increases the cross-sectional area of the spray nozzle compared to traditional nozzles. The increased cross-sectional area reduces the initial velocity of the water jet, weakens the jet effect, further reduces the impact noise of the water jet on the ceramic inner wall, and reduces the noise generated by the nozzle itself when spraying water (such as the noise generated by high-speed water jet impacting the inner wall of the spray), thereby further improving the noise reduction effect of the silencing toilet nozzle.

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0036] like Figures 1 to 5 As shown, this embodiment discloses a silent toilet spray head, including a spray head body 41, a nozzle 42 and a fixing member 43. The nozzle 42 is installed on one side of the spray head body 41 through the fixing member 43. The side of the nozzle 42 away from the spray head body 41 is provided with a spraying part 421 that communicates with the spray head body 41.
[0037] The diameter of the spray section 421 is smaller than the length of the spray section 421;
[0038] The cross-sectional area of the spray section 421 is smaller than the cross-sectional area of the nozzle body 41.
[0039] This invention improves the structure of the spray head by making the diameter of the spray section smaller than its length. This design enables the silent toilet spray head to feature laminar flow, meaning the water flows in a laminar state within the spray section. This causes the sprayed water to form a water column with minimal scattering in all directions, resulting in less water splashing. This significantly reduces the impact noise caused by the high-intensity impact of scattered water droplets on the ceramic inner wall and water surface, achieving a noise reduction effect. Furthermore, due to the laminar flow design, the water column sprayed from the silent toilet spray head has a higher central water velocity, increasing the fluid's range and ensuring the water reaches the front of the toilet bowl, guaranteeing effective flushing.
[0040] Specifically, laminar flow is a fluid flow state characterized by layered flow. When a fluid flows at low speed within a pipe, it exhibits laminar flow, with its particles moving smoothly in a straight line parallel to the pipe axis. The fluid velocity is highest at the center of the pipe and lowest near the wall. This invention improves the nozzle structure to achieve laminar flow within the spray section, effectively reducing the noise generated by the nozzle itself during spraying (i.e., the collision noise from water jets colliding with each other) and the impact noise from the water jet hitting the ceramic inner wall. This achieves noise reduction and silencing. Using this silent toilet nozzle in a toilet can significantly reduce flushing noise.
[0041] In one embodiment, the ratio of the diameter of the spray section 421 (as shown by d1 in the figure) to the length of the spray section 421 (as shown by L1 in the figure) is 1:1.15 to 1:2.25.
[0042] The nozzle structure is improved so that the ratio of the nozzle diameter to the length of the spray section 421 is 1:1.15 to 1:2.25, making the silent toilet nozzle a laminar flow design. The water flow within the spray section 421 forms a laminar flow state, with a parabolic velocity distribution. That is, the water flow velocity is fastest at the center of the spray section 421 and slowest near the inner wall. This allows the water jet from the spray section 421 to converge into a water column. Furthermore, the slower velocity at the outer periphery significantly reduces water splash scattering, virtually eliminating water splashes in all directions. Compared to traditional nozzles, this nozzle significantly reduces the impact noise generated by the high-intensity impact of scattered water splashes on the ceramic inner wall, achieving a noise reduction effect. Moreover, due to the laminar flow design, the faster velocity at the center of the water column from the silent toilet nozzle 4 increases the fluid range, allowing the water to reach the front of the toilet bowl, ensuring effective flushing.
[0043] In one embodiment, the flow cross-sectional area of the injection section 421 is 63 mm. 2 ~154mm 2 The flow cross-sectional area of the injection section 421 is controlled to be 63 mm. 2 ~154mm 2 This design increases the cross-sectional area of the spray section 421 compared to the nozzle of a conventional spray head. This increased cross-sectional area reduces the initial velocity of the water jet, weakens the jetting effect, further reduces the impact noise of the water against the ceramic inner wall, and reduces noise generated during water spraying (such as noise from high-speed water impacting the inner wall of the spray coating). This, in turn, further enhances the noise reduction effect of the silencing toilet spray head. Specifically, the cross-sectional area of the spray section 421 is 63 mm². 2 ~154mm 2 Within this range, it can effectively reduce water spray noise while ensuring flushing performance. Furthermore, within this range, the larger the flow cross-sectional area, the lower the noise. If the flow cross-sectional area is greater than 154mm... 2 This will lead to a decrease in flushing performance if the cross-sectional area of the flow path is less than 63mm. 2 The high speed of the water jet creates a jet effect, resulting in loud noise from the nozzle.
[0044] Specifically, the flow cross-sectional area refers to the effective cross-sectional area within the pipe (in this utility model, the jet section 421) that allows the medium (such as fluid, gas, etc.) to flow through; it is also called the "flow area". For example, for a circular pipe, the formula for calculating the flow cross-sectional area is S = π × (inner diameter / 2). 2 The inner diameter is the diameter inside the pipe.
[0045] In this invention, the cross-sectional shape of the spray section 421 can be a single circle, composed of multiple circles, or other shapes such as a crescent shape, as long as the flow cross-sectional area of the spray section 421 is controlled to be 63mm². 2 ~154mm 2 It can achieve good noise reduction and sound attenuation effects within a certain range.
[0046] In one embodiment, the diameter of the spray section 421 (as shown by d1 in the figure) is 9mm to 14mm. By controlling the diameter of the spray section 421 to be 9mm to 14mm, noise can be effectively reduced while ensuring flushing performance. Specifically, a diameter of 8mm to 15mm can reduce the jet effect, resulting in a lower initial velocity of the water jet from the spray section 421, thereby effectively reducing the noise from the water flushing. Simultaneously, because the initial velocity of the water jet from the spray section 421 is lower, the noise generated by the water jet impacting the inner wall of the toilet bowl can be reduced, thus reducing the overall noise of the toilet flushing. If the diameter of the spray section 421 is less than 8mm, the spray will produce a jet effect, resulting in high noise; if the diameter of the spray section 421 is too large, the toilet flushing effect will be poor.
[0047] Specifically, the diameter of the spray section 421 is exemplarily 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm, but is not limited thereto.
[0048] In one embodiment, the length of the spray section 421 (as shown by L1 in the figure) is 15mm to 20mm, making the silent toilet nozzle a laminar flow design. The water sprayed from the silent toilet nozzle will converge to form a water column, thereby further reducing noise. Specifically, the nozzle length of traditional nozzles is relatively short, causing the water flow inside the traditional nozzle to be in a turbulent state, resulting in greater noise from the spray. Moreover, the sprayed water is scattered, easily creating water splashes. These scattered water splashes impact the ceramic inner wall in all directions, generating noise, resulting in very loud flushing noise. The collision between water splashes also produces a certain amount of noise. The silent toilet nozzle of this utility model adopts a laminar flow design, which not only reduces the noise of the spray, but also ensures that the water sprayed from the silent toilet nozzle forms a water column. The water sprayed from the nozzle will not produce scattered water splashes impacting the toilet, thereby greatly reducing impact noise and achieving a noise reduction and silencing effect. Furthermore, in order to create a laminar flow effect and reduce flushing noise, the length of the silent toilet nozzle should not be too short. If it is too short, the noise reduction effect will be insignificant or the laminar flow effect will not be produced. The length of the spray section 421 is exemplarily 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm, but is not limited to these.
[0049] In one embodiment, the spray section 421 is a hollow cylinder, the cross-sectional area of the flow in each position inside the spray section 421 is equal, and the inner diameter is 9mm to 14mm. By limiting the length of the spray section 421 to 15mm to 20mm, excellent noise reduction and sound attenuation effects can be obtained.
[0050] In some embodiments, the inner diameter of the nozzle body 41 is 18mm to 25mm.
[0051] In one embodiment, the nozzle 42 includes a connecting portion 422 and a spray portion 421 that are in communication with each other, the spray portion 421 being mounted on the side of the connecting portion 422 away from the nozzle body 41;
[0052] The nozzle body 41 has a limiting mounting groove 411 on the side near the nozzle 42. The fixing member 43 is connected to the nozzle body 41. The fixing member 43 has a snap-fit hole 431 on the side away from the nozzle body 41. The size of the snap-fit hole 431 is smaller than the size of the connecting part 422. The side of the connecting part 422 away from the spray part 421 is installed in the limiting mounting groove 411, and the other side of the connecting part 422 passes through the snap-fit hole 431 and protrudes from the outside of the fixing member 43. Effect: This structure achieves radial positioning of the nozzle 42 through the limiting mounting groove 411 and axial fixation by utilizing the size difference between the snap-fit hole 431 and the connecting part 422. This allows for precise fixing of the nozzle 42 and ensures a seal, facilitating quick disassembly and maintenance of the nozzle body 41, nozzle 42, and fixing member 43. It effectively prevents vibration-induced loosening and has advantages such as high installation efficiency, strong vibration resistance, and convenient maintenance.
[0053] In one embodiment, the fixing member 43 is hollow on the side near the nozzle body 41, forming a mounting groove (not shown in the figure) for connecting the nozzle body 41. The inner wall of the mounting groove has an internal thread, and the outer wall of the nozzle body 41 near the fixing member 43 has an external thread. The side of the nozzle body 41 near the fixing member 43 is installed in the mounting groove, and the fixing member 43 and the nozzle body 41 are threadedly connected by the engagement of the internal thread and the external thread. The engagement of the internal thread and the external thread ensures a tight connection between the fixing member 43 and the nozzle body 41, preventing water leakage during spraying.
[0054] In one embodiment, the connecting portion 422 is shaped like a frustum. The side of the connecting portion 422 that is installed for connection with the nozzle body 41 is a first connecting portion (not shown in the figure). The shape and size of the limiting mounting groove 411 are adapted to the shape and size of the first connecting portion. By setting the connecting portion 422 to a frustum shape with an arc-shaped side, and by adapting the shape and size of the limiting mounting groove 411 to the shape and size of the first connecting portion, the first connecting portion and the limiting mounting groove 411 are in close contact, preventing water leakage from the nozzle during spraying.
[0055] Accordingly, a silent toilet is also disclosed, including a toilet body 1, a toilet bowl 2, a siphon pipe 3 and the aforementioned silent toilet nozzle 4, wherein the toilet bowl 2, the siphon pipe 3 and the silent toilet nozzle 4 are all installed inside the toilet body 1;
[0056] The toilet bowl 2 includes a toilet bowl body 21 and a water flow guide part 22 located on the top outer periphery of the toilet bowl body 21. The silent toilet nozzle 4 is installed on one side of the water flow guide part 22, and the water outlet of the silent toilet nozzle 4 faces the front end of the water flow guide part 22.
[0057] The toilet bowl body 21 is provided with a drain outlet 214 at the bottom, and the siphon pipe 3 is provided with a siphon inlet 31. The drain outlet 214 and the siphon inlet 31 are connected.
[0058] Applying the noise-reducing toilet nozzle of this invention to a toilet can effectively reduce toilet flushing noise and improve the user experience.
[0059] In one embodiment, the water flow guide portion 22 protrudes from the periphery of the toilet bowl body 21. The water flow guide portion 22 includes a water flow guide platform 221 and a raised periphery 222 surrounding the outer periphery of the water flow guide platform 221. The inner periphery of the water flow guide platform 221 is connected to the top of the toilet bowl body 21. A water flow guide groove 223 is formed between the surface of the water flow guide platform 221 and the inner wall of the raised periphery 222. The spray portion 421 is located in the water flow guide groove 22, and gaps are provided between the spray portion 421 and the raised periphery 222, as well as between the spray portion 421 and the water flow guide platform 221.
[0060] The connection between the raised edge 222 and the water flow guiding platform 221 is smoothly transitioned, making the connection point a smooth curved surface. Similarly, the connection between the water flow guiding platform 221 and the toilet bowl body 21 is also smoothly transitioned, resulting in a smooth curved surface at the connection point. This allows the water jet from the silent toilet nozzle 4 to flow more smoothly within the water flow guiding channel 223 and the toilet bowl body 21, reducing impact noise caused by water collisions. Furthermore, the water jet from the silent toilet nozzle 4, constrained by the water flow guiding channel 223, undergoes a spiral motion within the toilet bowl 2, forming a vortex flow similar to a "tornado," i.e., vortex flushing. This is significantly less noisy than the traditional direct-flush flushing method, which produces a loud noise when the water jet impacts the water surface vertically. 10 With a noise level reaching 75dB, the vortex water flow is slowly injected tangentially, reducing the collision energy between the water and the inner wall of the toilet bowl 2, thus reducing noise. Moreover, the vortex flow formed by the vortex flushing enhances the flushing force on the inner wall of the toilet bowl 2 due to its centrifugal force and momentum. The vortex water flow spirals downward along the inner wall of the toilet bowl 2, covering the "dead corners" of traditional flushing (such as the upper part of the inside of the toilet bowl and around the drain outlet), reducing dirt residue and making the flushing more thorough.
[0061] In one embodiment, the water flow guiding platform 221 is tilted downwards from front to back at an angle of 1° to 10°, so that the water flow from the silent toilet nozzle 4 is smoother and the impact noise caused by water flow collision is further reduced.
[0062] In one embodiment, the top of the toilet bowl body 21 is elliptical or quasi-elliptical, and the outline shape of the water flow guide 22 is adapted to the shape of the top of the toilet bowl body 21.
[0063] The toilet body 21 is provided with an integrally formed front wall 211, side wall 212 and rear wall 213, and the top ends of the front wall 211, the side wall 212 and the rear wall 213 are smoothly connected to the water flow guiding platform 221 respectively.
[0064] The angle between the water flow guiding platform 221 and the front wall 211 is greater than the angle between the water flow guiding platform 221 and the side wall 212, which is greater than the angle between the water flow guiding platform 221 and the rear wall 213. This makes the water flow smoother. Moreover, because the angle between the water flow guiding platform 221 and the front wall 211 is larger, meaning the front wall 211 is relatively flatter, most of the water sprayed from the silent toilet nozzle 4 flows from the front wall 211 to the bottom of the toilet bowl body 21, followed by the side wall 212, and a small portion flows from the rear wall 213 to the bottom of the toilet bowl body 21, resulting in a better flushing effect.
[0065] It is worth noting that the present invention designs the water flow guide 22 and the toilet bowl body 21 in such a way that the connection points of each surface of the water flow guide 22 and the toilet bowl body 21 are all arc-shaped, which is more in line with fluid mechanics, making the water flow more smoothly and the overall water flow smoother, reducing the impact of water on the inner wall of the ceramic, and further reducing the overall noise of the flushing process.
[0066] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
