Description

Technical Field

[0001] The utility model relates to the field of sanitary ware, in particular to a noise-reducing main flushing component for a toilet. Background Art

[0002] In order to improve the flushing effect of existing ceramic toilets, the brush ring is usually filled with water first to flush the waste into the siphon outlet, and then the main flush is performed to flush the waste away with high-pressure water. The strong high-pressure water quickly creates negative pressure in the siphon tube, thereby forming a siphon effect, sucking the waste into the sewage pipe. Therefore, a flush valve is installed at the position opposite the siphon outlet;

[0003] However, after the existing flush valve for main flush is opened, the high-pressure water flow will generate strong noise during the impact process. At the beginning, since the brush circle water has not yet flowed out, the noise in the main flush opening stage is small, but when it reaches the latter part of the flush, the brush circle water and dirt have been discharged. At this time, the main flush valve continues to flush water, and the noise generated by the collision with the ceramic wall and the splashing water seriously affects the user experience, especially late at night when it is quiet, the noise is particularly obvious.

[0004] In summary, the existing flush valve for main flushing needs to be further improved. Utility Model Content

[0005] The purpose of the present utility model is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a noise-reducing main flushing member for a toilet, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problem that the existing main flushing valve is noisy and easy to splash water during the second half of flushing.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A noise-reducing main flushing member for a toilet, comprising a main body and a water inlet, a water flow portion and a water ejection port arranged on the main body; further comprising a noise reduction structure arranged on the main body; the noise reduction structure comprising a slow-flow channel and a diversion port; the slow-flow channel is opened in the main body and is independently arranged in a staggered manner with the water flow portion; the diversion port and the water ejection port are on the same side and are arranged up and down; wherein the diversion port is located above the water ejection port, and the water outlet area of ​​the diversion port is larger than the water outlet area of ​​the water ejection port; the slow-flow channel supplies water to the diversion port, and causes the water from the diversion port to mix downward into the water column ejected from the water ejection port.

[0008] Furthermore, the water inlet includes a first water inlet end and a second water inlet end, the first water inlet end is used to connect the toilet water tank and the water flow part to supply water to the water outlet; the second water inlet end is used to connect the slow flow channel and the municipal waterway to supply water to the diversion port.

[0009] Furthermore, the water passing portion connected to the water ejection port has a tapered inclined surface; the tapered inclined surface is arranged to be tapered along the axial direction of the main body toward the water ejection port to form a high-pressure jet.

[0010] Furthermore, the cross-section of the water ejection port is crescent-shaped.

[0011] Furthermore, the main body includes a water inlet seat, a water outlet pipe body and a locking piece for fixing the water outlet pipe body to the water inlet seat; the water inlet seat is provided with an assembly cavity, and the assembly cavity conducts the first water inlet end and the second water inlet end; the water outlet pipe body is formed with the water flow portion, the water outlet and the noise reduction structure; wherein, the water outlet pipe body is correspondingly installed in the assembly cavity and fixed by the locking piece, so that the first water inlet end and the second water inlet end correspond to the slow flow channel of the water flow portion and the noise reduction structure respectively.

[0012] Furthermore, the water inlet directions of the first water inlet end and the second water inlet end are arranged perpendicular to the water outlet directions of the water passing portion and the slow flow channel.

[0013] Furthermore, it also includes an assembly ring, which cooperates with the threaded portion formed on the outer periphery of the water outlet pipe body and the water inlet seat, and cooperates with the end face of the water outlet pipe body to form an annular groove for clamping the wall surface of the toilet body.

[0014] Furthermore, the cross-section of the guide port is semicircular.

[0015] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The utility model provides a noise-reducing main flushing part for a toilet, which has a simple structure, is easy to manufacture, easy to implement and has low cost. The utility model simply opens a slow-flow channel on the main body and sets it above the water jetting port, and uses the water flow to slowly flow from top to bottom and merge into the water flow ejected from the water jetting port, thereby reducing the impact force of the water jetting from the water jetting port hitting the wall. Moreover, the water outlet area of ​​the diversion port is larger than the water outlet area of ​​the water jetting port, so that the slow-flowing water can cover the water jetting from the water jetting port. The formed water column can ensure the retention of water potential and sufficient water volume, and can also reduce and avoid the noise during flushing, especially the noise generated when there is no water or low water volume at the siphon after the siphon is formed, thereby improving the toilet flushing experience in a quiet environment.

[0017] (2) The water inlet portion of the present invention includes a first water inlet end and a second water inlet end, thereby ensuring that the water flow portion corresponding to the water jet port and the slow flow channel corresponding to the diversion port correspond to two different water inlet ends respectively, so that the water volume and potential energy of the water tank can still be maintained in the water jet port, ensuring the strength of the water jet flushing, while the diversion port portion is connected to the municipal waterway and will not take away the water volume of the water tank. Moreover, the water flow connected to the municipal waterway is relatively slow and will not affect the flushing potential energy.

[0018] (3) The water flow portion of the present invention is formed with a tapered inclined surface, and the cross-sectional shape of the water jet is set to a crescent shape. On the premise that the water tank discharges water downward to increase the potential energy, the potential energy is further increased by the tapered inclined surface to ensure the impact force of the main flushing water, and then the water is sprayed out from the crescent-shaped water jet, thereby improving the flushing effect while ensuring the water shape.

[0019] (4) The present invention separates the main body, which is not only easier to assemble but also easier to process and shape; in addition, the first water inlet end and the second water inlet end are arranged perpendicular to the water flow part and the slow flow channel, which reduces the volume of the entire main body and achieves miniaturization.

[0035] The outer periphery of the water outlet pipe body 22 is formed with a plurality of grooves 225 for mounting the sealing ring 7 and a threaded portion 226. The threaded portion 226 is used to be threadedly connected to the water inlet seat 21 and to be threadedly engaged with the locking member 23.

[0036] The water outlet pipe body 22 is correspondingly installed in the assembly cavity 211 and fixed by the locking member 23, so that the first water inlet end 212 and the second water inlet end 213 correspond to the slow flow channel 61 of the water passing part 4 and the noise reduction structure 6 respectively;

[0040] Actual assembly and use:

[0041] (1) The water inlet seat 21 and the water outlet pipe body 22 are prepared by injection molding; the water inlet seat 21 is formed with an assembly cavity 211 and a first water inlet end 212 and a second water inlet end 213 connected to the assembly cavity 211; and the water outlet pipe body 22 is also formed by injection molding to form a water inlet portion on the side, one end of which is formed with a semicircular guide port 62 and a crescent-shaped water outlet 5, and the other end has an internal thread for the installation of the locking member 23;

[0042] (2) The water outlet pipe 22 is passed through the bottom of the toilet bowl (i.e., the siphon port) so that the end face of the water outlet pipe 22 with the water ejection port 5 is located inside the bowl (the bowl here refers to the part of the toilet that holds waste), and the other end is placed outside the toilet bowl. After passing through the gasket, the assembly ring 8, and the assembly cavity 211, the water outlet pipe 22 is pre-locked with the water inlet seat 21 by the locking member 23.

[0043] (3) Adjust the water outlet pipe 22 so that its upper guide port 62 is located above the water jet port 5, first lock the locking member 23, and then screw the assembly ring 8 to lock it, so that the water outlet pipe 22 and the assembly ring 8 clamp the toilet pot wall;

[0044] (4) The first water inlet end 212 and the second water inlet end 21 of the water inlet seat 21 are respectively connected to the water tank connecting pipe and the connecting pipe connected to the municipal water to complete the entire assembly process.

[0045] When using:

[0046] Open the flush valve, and the water will first flush the brush circle to flush the dirt to the bottom of the pot surface; then switch to the main flushing circuit for flushing. At this time, the water in the water tank enters from the first water inlet end 212, is amplified by the water part 4, and is ejected from the water outlet 5. The dirt is flushed into the sewage pipe (at the siphon port) and discharged by siphoning. At the same time, the second water inlet end 213 is also flushed, and flows through the slow flow channel 61 to the diversion port 62. Due to the weak water momentum, it flows downward into the water flow ejected from the water outlet 5, and the area of ​​the diversion port 62 is larger than the area of ​​the water outlet 5 to form a cover, thereby reducing the noise generated by the impact on the wall of the toilet.

[0047] The utility model provides a noise-reducing main flushing part for a toilet, which has a simple structure, is easy to make, easy to implement and has low cost. The utility model simply opens a "slow flow channel" on the main body and arranges it above the water jetting port, and uses the water flow to slowly flow from top to bottom and merge into the water flow sprayed from the water jetting port, thereby slowing down the impact of the water jetting from the water jetting port on the wall. Moreover, the water outlet area of ​​the guide port is larger than the water outlet area of ​​the water jetting port, so that the slow-flowing water can cover the water jetted from the water jetting port, and the formed water column can ensure the retention of water potential and sufficient water volume, and can reduce and avoid the noise during flushing, especially after the siphon is formed, the noise generated when there is no water or low water volume at the siphon port, thereby improving the flushing experience in a quiet environment. The water inlet part described in the utility model includes a first water inlet end and a second water inlet end, so as to ensure that the water flow part corresponding to the water jetting port and the corresponding guide port are The slow-flow channel of the outlet corresponds to two different water inlet ends respectively, so that the water outlet part still maintains the water volume and potential energy of the water tank, ensuring the strong water jet flushing, while the diversion outlet part is connected to the municipal waterway, will not divert the water volume of the water tank, and the water potential connected to the municipal waterway is slow, which will not affect the flushing potential energy; the water flow part of the new model is formed with a gradually tapering inclined surface, and the cross-sectional shape of the water outlet is set to a crescent shape. On the premise that the water tank discharges water downward to increase the potential energy, the potential energy is further enhanced by the gradually tapering inclined surface to ensure the impact force of the main flushing water, and then sprayed out from the crescent-shaped water outlet, thereby improving the flushing effect while ensuring the water shape; the new model divides the main body into two parts, which is not only easier to assemble, but also easier to realize in processing and molding; in addition, the first water inlet end and the second water inlet end are arranged perpendicular to the water flow part and the slow-flow channel to reduce the volume of the entire main body and achieve miniaturization.

[0048] The above description of the specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation on the protection scope of the present utility model.
