Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to a noise reduction nozzle assembly. Background Technology

[0002] Current brush ring nozzles generally use filter rectification to reduce brush ring noise. In practical applications, using a filter with a smaller pore size can more effectively achieve rectification, thus significantly reducing flushing noise and also helping to reduce aeration noise. However, filter screens with smaller pore sizes are prone to scaling due to water quality issues, and impurities in the water are more likely to accumulate on the filter surface. Over time, this causes the water flow rate from the nozzle to gradually decrease, ultimately affecting the flushing effect of the brush ring and leading to incomplete rinsing. On the other hand, while using a filter with a larger pore size can delay the decrease in nozzle flow rate caused by scaling or impurity accumulation to some extent, this design performs poorly in noise reduction, making it difficult to effectively control noise levels. It also increases the risk of splashing water, affecting user comfort and cleaning effectiveness. Utility Model Content

The water outlet channels include a central water outlet channel located at the center of the nozzle body and a plurality of peripheral water outlet channels arranged around the central water outlet channel.

[0006] Furthermore, the water outlet face of the nozzle body is inclined to the axis of the central water outlet channel and the outer water outlet channel.

[0007] Furthermore, the nozzle includes a rotating part and a water outlet part connected to each other. The rotating part is provided with a water passage, and the water outlet part is provided with a central water outlet channel and a peripheral water outlet channel. The central water outlet channel and the peripheral water outlet channel are connected to the water inlet channel through the water passage channel. The water outlet end of the nozzle is provided with a mounting groove, and the rotating part is rotatably and sealedly installed in the mounting groove.

[0008] Furthermore, the outer side of the rotating part is provided with a spherical convex surface, and the mounting groove is provided with a spherical concave surface adapted to connect to the spherical convex surface, so that the water outlet part can adjust the water outlet direction 360 degrees.

[0009] Furthermore, a water outlet cover is fixedly connected to the water outlet end of the spray body. The water outlet cover restricts the nozzle to the water outlet end of the spray body, and the nozzle is completely located within the internal space of the water outlet cover.

Detailed Implementation

[0033] Example 1

[0034] The following is combined Figures 1-6 This utility model will be described in detail.

[0035] A noise reduction nozzle assembly 10 includes a spray body 20, the spray body 20 having a water inlet channel 2021, and a rotatable nozzle body 30 connected to the water outlet end of the spray body 20. Figure 6 As shown, the nozzle body 30 is provided with several water outlet channels, including a central water outlet channel 3011 and several peripheral water outlet channels 3012 arranged around the central water outlet channel 3011. The central water outlet channel 3011 and the peripheral water outlet channels 3012 are connected to the water inlet channel 2021.

[0036] This embodiment divides the water outlet channel of the nozzle body 30 into a central water outlet channel 3011 and an outer water outlet channel 3012, achieving natural diversion of the water flow during ejection and forming multiple independent and orderly water flow paths. This design facilitates the gradual transition of the water flow state from turbulent to laminar flow, thereby significantly reducing noise generated by turbulent disturbances. Simultaneously, by splitting the originally concentrated single water flow into multiple fine streams, the impact energy is effectively dispersed, avoiding local energy concentration and reducing the vibration amplitude and cavitation effect caused by water jetting, further suppressing noise generation at its source. Furthermore, the interference between the multiple fine streams after ejection is reduced, avoiding the high-frequency howling problem caused by strong vortices and shearing in traditional whole water flow. Therefore, this structural design not only optimizes the flow field distribution inside the nozzle, improving the stability and uniformity of the flow, but also significantly reduces the noise radiation level during the ejection process. At the same time, since it does not require the use of the filter structure commonly found in existing technologies, it also avoids the problems of impurities being retained in the water and scale clogging the channels caused by the use of filters. Thus, while achieving noise reduction, it further enhances the anti-clogging performance and system reliability.

[0037] like Figure 4 and Figure 5 As shown, the water outlet face of the nozzle body 30 is inclined to the axis of the central water outlet channel 3011 and the peripheral water outlet channel 3012. This facilitates the discharge of air mixture in the central water outlet channel 3011 and the peripheral water outlet channel 3012 and reduces air breakage and splashing, thereby reducing water flow noise and splashing. Specifically, the water outlet face is positioned close to the toilet brush ring wall, with its upper edge close to the spray body 20 and its lower edge away from the basin 20. Bubbles in the water flow float upwards and gather at the upper layer of the water flow, moving towards the water outlet face with the water flow. The bubbles at the upper layer of the water flow are discharged from the upper edge of the water outlet face, allowing the bubbles at the upper layer of the water flow to exit the water outlet face before the lower layer of water flow, thereby reducing the gas content in the sprayed water flow and thus reducing the possibility of water splashing.

[0038] like Figure 4 As shown, the nozzle body 30 includes a rotating part 302 and a water outlet part 301 connected to each other. The rotating part 302 is provided with a water passage 3021, and the water outlet part 301 is provided with a central water outlet channel 3011 and a peripheral water outlet channel 3012. The central water outlet channel 3011 and the peripheral water outlet channel 3012 are connected to the water inlet channel 2021 through the water passage 3021. The water outlet end of the spray body 20 is provided with a mounting groove, and the rotating part 302 is rotatably and sealingly installed in the mounting groove. Furthermore, a sealing ring is provided between the rotating part 302 and the mounting groove. The outer surface of the rotating part 302 is provided with a spherical convex surface, and the mounting groove is provided with a spherical concave surface adapted to connect to the spherical convex surface, so that the water outlet part 301 can adjust the water outlet direction 360 degrees, thereby adjusting the water outlet direction of the water outlet part 301 to be tangent to or nearly tangent to the toilet 100 wall surface, so as to reduce noise and splashing caused by water flow impact.

[0039] like Figure 1 as well as Figures 3 to 5 As shown, a water outlet cover 40 is fixedly connected to the water outlet end of the spray body 20. The water outlet cover 40 restricts the nozzle to the water outlet end of the spray body 20, and the nozzle is completely located within the internal space of the water outlet cover 40. This prevents the nozzle body 30 from being accidentally touched during the toilet 100 brushing process, thus changing the water outlet direction of the nozzle body 30 and affecting the noise reduction performance. Specifically, as shown... Figure 5 As shown, the distance between the end of the water outlet cover 40 furthest from the spray body 20 and the spray body 20 is L1, and the distance between the farthest end of the water outlet face of the nozzle body 30 and the spray body 20 is L2. L1 is slightly larger than L2 to ensure that the water outlet cover 40 completely covers the outside of the nozzle body 30. Furthermore, the water outlet cover 40 includes a cover body 401, and a limiting part 402 extending radially inward is provided on the inner side of the cover body 401. When the cover body 401 is connected to the spray body 20, the limiting part 402 restricts the nozzle body 30 within the mounting groove. The cover body 401 has a first connecting position 501, and the spray body 20 has a second connecting position 502. The first connecting position 501 and the second connecting position 502 are connected to each other, so that the cover body 401 is connected to the spray body 20. The first connecting position 501 and the second connecting position 502 can be a threaded connection or a snap-fit ​​structure.

[0040] The spray body 20 includes a main body 202 and a connecting portion 201 located at one end of the main body 202. The connecting portion 201 is connected to the nozzle body 30 and the water outlet cover 40. Therefore, the connecting portion 201 is provided with a mounting groove and a second connecting position 502. Furthermore, the radial dimension of the connecting portion 201 is larger than the dimension of the main body 202, so that the connecting portion 201 can abut against the outside of the brush ring mounting position 1101 of the toilet 100, which facilitates the fixed installation of the spray body 20 on the brush ring mounting position 1101.

[0041] like Figure 4As shown, the main body 202 is covered with an outer rubber pad 601, which abuts against the connecting part 201. The water inlet end of the spray body 20 is fitted with an inner rubber pad 602 and a locking member 70. The locking member 70 makes the outer rubber pad 601 and the inner rubber pad 602 fit against the outer and inner sides of the toilet brush ring mounting position 1101 of the toilet 100. The water inlet end of the spray body 20 is also connected to a water inlet pipe 80, and the water inlet end of the water inlet pipe 80 is connected to a water inlet connector 90.

[0042] Example 2

[0043] The following is combined Figures 7-13 This utility model will be described in detail.

[0044] This embodiment also proposes a toilet 100, including a toilet body 110. The toilet body 110 is provided with a brush ring mounting position 1101, and a noise-reducing nozzle assembly 10 as described above is installed in the brush ring mounting position 1101. The installation process of the noise-reducing nozzle assembly 10 is as follows:

[0045] The spray body 20, equipped with the nozzle body 30, water outlet cover 40, and outer rubber gasket 601, is passed through the brush ring mounting position 1101, so that the nozzle body 30, water outlet cover 40, and outer rubber gasket 601 are located inside the toilet body 110. The outer rubber gasket 601 and locking member 70 are then sequentially fitted onto the water inlet end of the spray body 20. The locking member 70 is rotated to clamp the outer rubber gasket 601 and inner rubber gasket 602 on the inner and outer sides of the brush ring mounting position 1101, completing the installation of the spray body 20. Subsequently, the water inlet pipe 80 is connected to the water inlet end of the spray body 20, and connected to the water supply system through the water inlet connector 90, ensuring that there is no leakage at any sealing part.

[0046] After the water is turned on, rotate the nozzle body 30 to adjust the water outlet direction of the water outlet 301 to be tangent to or close to the inner wall surface of the toilet 100, so that the water flows smoothly down the wall surface, effectively reducing impact noise and splashing.

[0047] In this embodiment, the toilet 100 is equipped with the aforementioned noise-reducing nozzle assembly 10, which significantly reduces the noise generated by the water flow around the brush ring. Compared with other brush ring structures, the noise reduction effect is more pronounced with increasing water pressure, reducing noise by up to 7-8 decibels. Test data is as follows: Figure 13 As shown.

[0048] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model.
