[0020] In existing toilets, brush flushing and siphon flushing are generally performed separately through flush valve assemblies. However, the flush valve assemblies on the market are relatively noisy, and the flushing noise can have a significant impact on users when using smart toilets in the quiet of the night or in the morning.

[0021] This application reduces the flushing noise of the flushing valve assembly by providing a porous buffer in at least one liquid outlet channel of the valve body.

[0022] To facilitate the reader's understanding of the inventive concept of this utility model, the specific structure of the flushing valve assembly is described below: Please see Figure 1-2The flushing valve assembly 100 includes a valve body 1 and a porous buffer 2. The valve body 1 is provided with an inlet channel 11 and at least two outlet channels 12, each of which is connected to the inlet channel 11. The porous buffer 2 is disposed within at least one outlet channel 12 and has a pore structure 221 extending along the fluid direction X, used to disperse and buffer the liquid flow through the outlet channel 12, thereby reducing flushing noise. This application reduces flushing noise in the outlet channel 12 by providing a porous buffer 2 within at least one outlet channel 12 of the valve body 1, allowing the liquid flow through the outlet channel 12 to pass through the porous buffer 2.

[0023] In some embodiments, the porous buffer 2 includes a fiber bundle structure 21, in which the fibers can undergo elastic deformation under the action of fluid, which is beneficial for dispersing and buffering the liquid flow through the liquid outlet channel 12.

[0024] In some embodiments, please refer to the following: Figure 3 The fiber bundle structure 21 includes a fixed column 211 and multiple fiber bundles 212. The fixed column 211 is fixed to the liquid outlet channel 12. One end of the multiple fiber bundles 212 is fixed to the fixed column 211, and the other end of the multiple fiber bundles 212 abuts against the wall of the liquid outlet channel 12. A pore structure 221 is formed between the multiple fiber bundles 212, which is conducive to the multiple fiber bundles 212 and the liquid flow of the liquid outlet channel 12 to fully contact each other, so as to further improve the noise reduction effect.

[0025] In some embodiments, the fiber bundle structure 21 is a brush.

[0026] In some embodiments, the porous buffer 2 further includes a screen and a filter.

[0027] In some embodiments, the pore structure 221 is uniformly arranged, which is beneficial to uniformly disperse and buffer the liquid flow through the liquid outlet channel 12, so as to further improve the noise reduction effect.

[0028] In some embodiments, please refer to Figure 4 There are two outlet channels 12, and each outlet channel 12 is equipped with a porous buffer 2, which can further reduce the flushing noise of the flushing valve assembly 100.

[0029] In some embodiments, please refer to Figure 5The valve body 1 is equipped with an integrated connection structure 13, including: a first connection end 131 connected to the inlet pipe 3, and a second connection end 132 connected to the siphon flushing pipe 4 and the brush ring flushing pipe 5 respectively. The inlet pipe 3 is connected to the inlet channel 11 through the first connection end 131, and the siphon flushing pipe 4 and the brush ring flushing pipe 5 are connected to the outlet channel 12 through the second connection end 132. The inlet pipe 3 is used to transport external liquid to the inlet channel 11, the siphon flushing pipe 4 is used to transport the liquid from the outlet channel 12 to the bottom of the toilet for siphon flushing, and the brush ring flushing pipe 5 is used to transport the liquid from the outlet channel 12 to the side of the toilet for brush ring flushing. The porous buffer 2 is positioned close to the second connection end 132, which facilitates the installation and removal of the porous buffer 2 through the second connection end 132.

[0030] In some embodiments, the first connecting end 131 and the second connecting end 132 can be a threaded connection structure, a flange connection structure, a quick coupling connection structure, or a welded structure.

[0031] In some embodiments, the inlet pipe 3, the siphon flushing pipe 4, and the brush ring flushing pipe 5 are braided pipes.

[0032] In some embodiments, the flush valve assembly 100 further includes a siphon nozzle (not shown) and a brush ring nozzle (not shown). The siphon nozzle is disposed at one end of the siphon flush pipe 4 away from the second connection end 132, and the brush ring nozzle is disposed at one end of the brush ring flush pipe 5 away from the second connection end 132. The siphon nozzle is used to spray the liquid in the siphon flush pipe 4 to the bottom of the toilet for siphon flushing, and the brush ring nozzle is used to spray the liquid in the brush ring flush pipe 5 to the side of the toilet for brush ring flushing.

[0033] In some embodiments, the integrated connection structure 13 further includes a third connection end 133 connected to the siphon flushing pipe 4 and a fourth connection end 134 connected to the brush ring flushing pipe 5. The siphon flushing pipe 4 is connected to the siphon nozzle through the third connection end 133, and the brush ring flushing pipe 5 is connected to the brush ring nozzle through the fourth connection end 134.

[0034] In some embodiments, the third connection end 133 and the fourth connection end 134 can be threaded connection structures, flange connection structures, quick coupling connection structures or welded structures.

[0035] In some embodiments, please refer to the following: Figure 6 The porous buffer 2 includes a buffer section 22 and a mounting section 23 connected together. The porous structure 221 is located in the buffer section 22, and the mounting section 23 is installed in the liquid outlet channel 12. The mounting section 23 is closer to the second connecting end 132 than the buffer section 22, which is conducive to the installation and removal of the mounting section 23 through the second connecting end 132.

[0036] In some embodiments, the flushing valve assembly 100 further includes a flow distribution structure (not shown), in which the porous buffers 2 in the two outlet channels 12 have different pore parameters to meet the different flow requirements of siphon flushing and brush ring flushing. For example, the porous buffer 2 in the outlet channel 12 connected to the siphon flushing pipe 4 has a pore structure 221 with a large pore diameter and low pore density, ensuring a large flow rate per unit time and quickly forming a siphon effect. The porous buffer 2 in the outlet channel 12 connected to the brush ring flushing pipe 5 has a pore structure 221 with a small pore diameter and high pore density, which reduces the instantaneous flow rate and prolongs the flushing time by dispersing the liquid flow.

[0037] In some embodiments, the flow distribution structure includes a valve core rotatably disposed within the liquid outlet channel 12. By adjusting the angle of the valve core, the opening area of ​​the liquid outlet channel 12 can be adjusted, thereby adjusting the size of the liquid flow in the liquid outlet channel 12, and thus adjusting the flow rate of the siphon flushing and brush ring flushing.

[0038] In some embodiments, the flow distribution structure further includes a piston movably disposed within the liquid outlet channel 12. By adjusting the position of the piston, the opening area of ​​the liquid outlet channel 12 can be adjusted, thereby adjusting the size of the liquid flow in the liquid outlet channel 12, and thus adjusting the flow rate of the siphon flushing and brush ring flushing.

[0039] This utility model also provides a toilet embodiment, which includes the above-mentioned flush valve assembly 100. The function and structure of the flush valve assembly 100 can be referred to the above embodiment, and will not be repeated here.
