Description

Technical Field

[0001] This utility model relates to the field of smart toilets, specifically a smart toilet silent drainage device. Background Technology

[0002] In modern home life, smart toilets have gradually become a standard feature in bathrooms due to their convenience and comfort. However, traditional smart toilets generally have noise problems during the drainage process, which seriously affects the user experience. Silent drainage of smart toilets is a technology designed to reduce the noise generated during the toilet drainage process. It optimizes the drainage system in various ways to provide users with a quieter and more comfortable environment. High-quality toilet ceramic materials have high density and uniform thickness, which can block the transmission of sound to a certain extent. In addition, some toilet brands add sound insulation materials inside the toilet, such as sound insulation cotton, which can significantly reduce the sound of flushing and water flow impact.

[0003] Existing smart toilets have drainage pipes that are directly connected to the toilet bowl. The high-speed water flow impacts the pipe walls, producing a sharp and noisy sound that is particularly jarring in a quiet home environment. At the same time, the drainage pipes are not effectively soundproofed, allowing the noise to easily penetrate the walls and spread to adjacent spaces, disturbing family members' rest or daily activities. To address this, we have proposed a silent drainage device for smart toilets. Utility Model Content

[0025] Furthermore, the soundproof shell structure includes a sound-absorbing shell 6, an external thread 8, and sound-absorbing cotton 9. A circular hole is provided through the side of the sound-absorbing shell 6 opposite to the opening. The circular hole of the sound-absorbing shell 6 is fixedly connected to the outer surface of the drain pipe 3. The sound-absorbing shell 6 is outside the drain pipe 3 and the sound-absorbing shell 6 and the drain pipe 3 are coaxial. The sound-absorbing shell 6 is close to the drain outlet of the toilet 1 and the opening of the sound-absorbing shell 6 is opposite to the toilet 1. An external thread 8 is provided on the outer cylindrical surface of the sound-absorbing shell 6 near the opening. The sound-absorbing cotton 9 is bonded to the inner cylindrical surface of the sound-absorbing shell 6. The sound-absorbing shell 6 is used to install the external thread 8, and the external thread 8 is used for sound insulation.

[0026] Furthermore, the soundproof shell structure also includes a cover tube 5, an insertion hole 7, and sound-absorbing cotton 14. The inner cylindrical surface of the cover tube 5 is provided with internal threads. An insertion hole 7 is provided through the side of the cover tube 5 opposite to the opening. Sound-absorbing cotton 14 is bonded to the side of the cover tube 5 opposite to the opening. The insertion hole 7 is inserted into the drain pipe 3. The cover tube 5 is sleeved with the sound-absorbing shell 6, and the internal thread of the cover tube 5 is threadedly connected to the external thread 8. The insertion hole 7 is used for the movable connection between the cover tube 5 and the drain pipe 3. The sound-absorbing cotton 14 is used for sound insulation. The cover tube 5 and the sound-absorbing shell 6 are movably connected by a threaded connection, which is convenient for disassembly and assembly, and for the inspection and cleaning of the sound-absorbing structure.

[0027] Furthermore, the sound-absorbing structure includes a sound-absorbing pipe 11 and inclined holes 15. The outer cylindrical surface of the drain pipe 3 is inclined downwards and has multiple evenly distributed inclined holes 15. The outer cylindrical surface of the drain pipe 3 is fixedly connected to the inclined holes 15 with an upward inclination. The sound-absorbing pipe 11 and the inclined holes 15 are coaxial. The sound-absorbing pipe 11 and the inclined holes 15 are inside the sound-absorbing cotton 9. The inclined holes 15 are used for sound absorption. The position where the drain pipe 3 is connected to the toilet 1 is close to the ground and needs to be soundproofed. The sound-absorbing pipe 11 is used to transmit noise to the sound-absorbing cotton 9 and the second sound-absorbing cotton 14. The inclined design of the inclined holes 15 and the sound-absorbing pipe 11 reduces the amount of water entering the sound-absorbing pipe 11.

[0028] Furthermore, the sound-absorbing structure also includes a filter screen 10, a sound-insulating membrane 12, and a rubber sound-insulating cloth 13. Filter screens 10 are snapped into the inclined holes 15 and fixedly connected to the inner wall of the inclined holes 15.

The end of the drain pipe 3 away from the toilet bowl 1 is fixedly connected to a water trap 4, and the other end of the water trap 4 is fixedly connected to one end of another water trap 4. The water traps 4 are all positioned downwards. The multiple water traps 4 can divide the water flow during the drainage process into multiple stages for buffering. When the water flow enters the sewage pipe from the toilet and encounters the first water trap, the water flow speed will be slowed down due to the obstruction of the water trap and the resistance of the water. Then it enters the next section of the pipe and water trap, and is buffered again, thereby reducing noise.

[0030] Structural Description:

[0031] Toilet 1: The common toilet shape is the main part used by the user, providing functions such as defecation. Its sewage outlet is connected to the drain pipe 3 to discharge sewage.

[0032] Base 2: It is generally square or in a shape that fits the toilet. It is used to support the toilet 1 and make the toilet 1 firmly installed on the bathroom floor. At the same time, the internal space can accommodate the drain pipe 3 and other structures.

[0033] Drain pipe 3: A tubular structure that connects the sewage outlet of toilet 1 to a multi-stage water trap structure (composed of multiple water traps 4), serving as a channel for sewage discharge.

[0034] Water trap 4: It is S-shaped. Multiple water traps 4 are connected in sequence to form a multi-stage water trap structure. It is used to form a water seal by storing water to prevent the backflow of sewer odors. At the same time, it buffers and slows down the drainage flow to reduce noise.

[0035] Cover tube 5: It is a hollow tube with an internal thread at one end for connecting with the external thread 8 of the sound-absorbing shell 6. There is an insertion hole 7 on the opposite side of the opening, which can be inserted into the drain pipe 3. Sound-absorbing cotton 14 is bonded inside to play a sound insulation role. The threaded connection with the sound-absorbing shell 6 makes it convenient to inspect and clean the internal sound-absorbing structure.

[0036] Sound-absorbing outer shell 6: It is a cylindrical shape with one end open. There is a round hole on the side opposite the opening, which can be fitted onto the outside of the drain pipe 3 and fixed thereto. There is an external thread 8 on the outer cylindrical surface near the opening, which is used to connect with the cover pipe 5. Sound-absorbing cotton 9 is glued to the inner cylindrical surface to absorb the noise transmitted from the drain pipe 3.

[0037] Insertion hole 7: A circular hole opened on the side opposite the opening of the cover tube 5, used for inserting the cover tube 5 into the drain pipe 3 to realize the movable connection between the cover tube 5 and the drain pipe 3;

[0038] External thread 8: Located on the outer cylindrical surface of the sound-absorbing housing 6 near the opening, it has a spiral pattern and is used to mate with the internal thread of the cover tube 5 to achieve a threaded connection between the two, enhance the tightness of the sound insulation structure and facilitate disassembly and assembly.

[0039] Sound-absorbing cotton 9: The material is fluffy and fits into the inner cylindrical surface of the sound-absorbing shell 6. Through its porous structure, it absorbs the noise transmitted from the drain pipe 3 and converts the sound energy into heat energy to achieve a sound insulation effect.

[0040] Filter screen 10: The shape is adapted to the inclined hole 15. It is mostly round and sheet-like, and is snapped into the inclined hole 15. It is made of silent filter plate material, which can not only filter impurities in sewage and prevent pipe blockage, but also play a certain role in blocking and absorbing noise.

[0041] Sound-absorbing tube 11: tubular structure, one end is fixedly connected to the outer cylindrical surface of the drain pipe 3 at an angle upward, and is coaxial with the inclined hole 15. It is used to transmit the noise generated by the water flow impact in the drain pipe 3 to the sound-absorbing cotton 9 and the sound-absorbing cotton 14. The inclined design can reduce the entry of sewage.

[0042] Sound insulation film 12: A thin film made of polymer material, in the shape of a circular sheet, is attached to the end of the sound-absorbing pipe 11 away from the drain pipe 3. Its special internal structure can reflect and absorb sound waves to reduce noise, while blocking small molecule odors and preventing odors from escaping.

[0043] Rubber sound insulation cloth 13: Made of neoprene rubber, it is soft in texture and has a cylindrical shape that fits the sound absorption tube 11. It is snapped into the sound absorption tube 11 and has good water resistance and corrosion resistance. It can absorb noise and prevent sewage from seeping in.

[0044] Sound-absorbing cotton 214: Similar in material to sound-absorbing cotton 19, it is fluffy and porous, and is bonded to the side opposite the opening of the cover tube 5 to help absorb noise and enhance the overall sound insulation effect;

[0045] Inclined hole 15: A circular hole with an inclination downwards is opened on the outer cylindrical surface of the drain pipe 3. Multiple inclined holes 15 are evenly distributed around the circumference to allow noise to enter the sound-absorbing pipe 11. The inclined design can reduce the amount of sewage entering the sound-absorbing pipe 11 during drainage, and at the same time, it is conducive to the transmission of noise.

[0046] Working principle: When water flow impacts and generates noise in the drain pipe 3, the noise enters the sound-absorbing pipe 11 through the inclined hole 15. The inclined hole 15 and the sound-absorbing pipe 11 are designed to reduce the amount of sewage entering the sound-absorbing pipe 11 during drainage, and also facilitate the propagation of noise. After entering the sound-absorbing pipe 11, the noise first passes through the filter screen 10, which is made of a silent filter plate material. While filtering impurities in the sewage, it also plays a certain role in blocking and absorbing noise. Next, the noise encounters the rubber sound insulation cloth 13, which is made of neoprene rubber. Soft and with good water and corrosion resistance, it effectively absorbs noise and prevents further sewage penetration. Finally, the noise reaches the sound insulation membrane 12, which is made of polymer material. Its special internal sound insulation structure can reduce noise by reflecting and absorbing sound waves, and at the same time, it can block some small molecule odors to prevent odors from escaping. After this series of structural treatments, most of the noise is absorbed and blocked, thereby reducing the amount of noise transmitted outward. At this time, the sound-absorbing shell 6 is fitted on the outside of the drain pipe 3, and the sound-absorbing cotton 9 bonded inside can absorb some of the noise. With a porous structure, when sound waves enter through the sound-absorbing tube 11, they cause the air molecules inside the sound-absorbing cotton 9 to vibrate, converting sound energy into heat energy and thus achieving sound insulation. Simultaneously, the cover tube 5 is threadedly connected to the external thread 8 of the sound-absorbing outer shell 6 via its internal thread, tightly fitting onto the sound-absorbing outer shell 6. The sound-absorbing cotton 14 bonded to the opposite side of the cover tube 5 further enhances the sound insulation effect. The threaded connection between the cover tube 5 and the sound-absorbing outer shell 6 not only ensures the tightness of the structure but also facilitates disassembly and assembly for inspection and cleaning of the internal sound-absorbing structure. The multi-stage water trap structure consists of multiple water traps... The water trap 4 is installed at the end of the drain pipe 3 away from the toilet 1. When the toilet 1 drains, the water flows from the toilet into the sewage pipe and first encounters the first water trap 4. The water in the water trap 4 will block the water flow, and the water flow speed will be slowed down due to the water resistance. Then, the water flow enters the next section of the pipe and the next water trap 4, and is buffered again. Through the continuous action of multiple water traps 4, the water flow in the drainage process is divided into multiple stages for buffering, so that the water flow speed is gradually reduced, avoiding the high-speed water flow impacting the pipe and generating a lot of noise, thus achieving a silent drainage effect.
