Description

Technical Field

[0001] The invention relates to the technical field of toilet exhaust, and in particular to a toilet self-purification ecological system used in toilets. Background Art

[0002] Toilets in public places usually contain multiple toilets. Even if the toilets are installed in separate compartments, after people use the toilet or clean it for hygiene, odors will inevitably be generated in the relatively closed room of the toilet. The odors usually contain ammonia. When the room is filled with too much ammonia, it will give people a bad user experience. Inhaling ammonia will also cause certain health risks to users. With the continuous improvement of people's living standards, people's attention to the environmental sanitation conditions of public toilets is also constantly improving, especially the problem of odor removal in multi-story public toilets such as hospitals, schools, and office buildings has also received more and more attention. There are many ways to remove odors from traditional multi-story public toilets, and there are also various technical improvements for water conservation and deodorization, such as opening windows for ventilation, exhaust fans for exhaust and odor removal, tap water flushing and drainage, S-bend water seals, or opening and closing one-way valves to isolate odor sources, etc. However, odor removal is not always thorough, and various methods and measures have disadvantages. For example, flushing and drainage through a large amount of tap water will cause high water consumption, and drainage through S-bends or one-way valves will easily form dirt inside, causing the water in the water seal to deteriorate, etc. Therefore, it is necessary to improve and perfect the existing multi-story public toilet odor removal technology.

[0028] See also Figure 1-3 , the embodiment of the present invention discloses a toilet self-cleaning ecosystem for a bathroom, comprising: a sanitary ware 1, with a discharge outlet 11 at the bottom;

[0029] A connecting member 2 is sleeved on the lower outer side of the exhaust port 11, and at least one exhaust channel 21 is provided on the side wall of the connecting member 2;

[0030] The exhaust duct 3 includes at least one first branch pipe 31, at least one first transverse pipe 32 and at least one first vertical pipe 33, wherein the first branch pipe 31 is tightly connected to the outside of the exhaust passage 21, the first transverse pipe 32 connects the first branch pipe 31 and the first vertical pipe 33, and both ends of the first vertical pipe 33 are connected to the external environment of the building;

[0031] At least one fan 4 is disposed in the first transverse pipe 32 or the first vertical pipe 33 .

[0032] Specifically, the external environment of the building is the septic tank 6 and / or the outside of the top of the building and / or the outside of the outer wall of the building; further, the bottom end of the first riser 33 is connected to the septic tank 6, and the top end is connected to the outside of the top of the building, or, the bottom end of the first riser 33 is connected to the outside of the outer wall of the building, and the top end is connected to the outside of the top of the building, or, the bottom end of the first riser 33 is connected to the septic tank 6, and the top end is connected to the outside of the outer wall of the building. The above three connection ends of the first riser 33 allow the gas to be eventually discharged from the room, discharged to the outside and diluted or treated.

[0033] In the present invention, the sanitary ware 1, that is, the sanitary ware, can be a urinal or a squat toilet, a connector 2 is sleeved below the discharge port 11 of the sanitary ware 1, and at least one exhaust channel 21 is provided on the side wall of the connector 2, specifically, the exhaust channel 21 is an exhaust hole opened on the side wall of the connector 2; the exhaust duct 3 includes at least one first branch pipe 31, at least one first transverse pipe 32 and at least one first vertical pipe 33, wherein the first branch pipe 31 is tightly connected to the exhaust hole, the first transverse pipe 32 connects the first branch pipe 31 and the first vertical pipe 33, both ends of the first vertical pipe 33 are connected to the external environment of the building, and a fan 4 is provided in the first transverse pipe 32 or the first vertical pipe 33, therefore, people When using or cleaning the sanitary ware 1, the gas / odor generated by the excrement or cleaning products can be discharged into the exhaust pipe 3 through the exhaust channel 21 on the side wall of the connector 2, and the fan 4 located in the first transverse pipe 32 or the first vertical pipe 33 is started to work, so that negative pressure is generated in the exhaust pipe 3, and then the gas is discharged from the first branch pipe 31, the first transverse pipe 32 and the first vertical pipe 33 to the external environment of the building in sequence. Preferably, the bottom end of the first vertical pipe 33 is connected to the septic tank 6, and the top end is connected to the top outside of the building, so that most of the gas can be discharged from the top outside of the building and diluted in the atmospheric environment, and a small amount can also be discharged downward to the septic tank 6 for subsequent purification or use. Therefore, the system structure provided by the present invention can significantly improve the exhaust effect of the toilet, effectively reduce the spread of odor in the room, and improve the indoor air quality. The fan 4 is arranged in the exhaust pipe 3 to produce a negative pressure self-purification effect, which can timely and quickly reduce the risk of pipe blockage, thereby reducing maintenance costs; and the unique structural design is easy to install and is suitable for public toilets in various building scenes.

[0034] In an optional embodiment, a sewage pipe 5 is further provided below the discharge port 11, one end of the sewage pipe 5 is sleeved on the inner side of the connecting piece 2, and the other end is connected to the septic tank 6; a sewage valve 7 is also provided on the inner side of the sewage pipe 5 below the exhaust channel 21, and the sewage valve 7 is used to sense whether an object falls into the discharge port 11 and automatically open the valve. This structure forms a deodorization and air purification deodorization system.

[0035] Specifically, the sanitary ware 1 used in the present invention is a straight-discharge sanitary ware 1, and the pipe connected below it is a straight-discharge pipe, which is different from the existing structure of an S-bend pipe that is usually used to absorb odor. When people are using the sanitary ware 1 to relieve themselves or clean themselves, the drain valve 7 automatically senses that an object has fallen from the upper drain port and automatically opens the valve, allowing the object to pass through the drain valve 7 and fall into the drain pipe 5, and finally flow into the septic tank 6. Most of the objects are human excrement or cleaning water. When it is not recognized that there are still objects falling, the drain valve 7 is automatically closed, thereby preventing the odor of the waste from overflowing from the drain pipe 5 and avoiding affecting people's use experience; at the same time, the drain valve 7 is arranged at a position below the exhaust channel 21, which can ensure that most of the waste is discharged from the drain valve 7 to avoid contamination of the exhaust channel 21.

[0036] Furthermore, the sanitary ware 1 and the discharge outlet 11, and even the inner wall of the connecting piece 2 and the sewage pipe 5 are all made of ceramic core material, and high-density material can be coated on the inner wall through nanotechnology to form a lotus leaf effect on its surface, preventing dirt from adhering to the inner wall and avoiding the odor of residual dirt from volatilizing into the room.

[0037] In an optional embodiment, a water supply disinfection and cleaning system is further included, and the water outlet of the water supply disinfection and cleaning system is connected to the inner wall of the sanitary ware 1, and is used to clean the inside of the sanitary ware 1. Specifically, the water supply disinfection and cleaning system is used to clean the inner wall of the sanitary ware 1, and flush a small amount of feces, urine stains and other dirt attached to the upper part thereof to the bottom of the drain valve 7, and take away the odor attached to the dirt.

[0038] In an optional embodiment, the exhaust duct 3 includes multiple groups of exhaust components located at different heights, and a single group of the exhaust components includes multiple first branch pipes 31 and one first transverse pipe 32. The first transverse pipe 32 is provided with multiple first transverse connection ports, and multiple first branch pipes 31 are respectively connected to the connection ports; the first vertical pipe 33 is provided with multiple first longitudinal connection ports, and multiple first transverse pipes 32 located at different heights are respectively connected to the first longitudinal connection ports. This structure is suitable for public places with multi-story toilets in buildings. Specifically, multiple sanitary ware 1 are individually connected to the first branch pipe 31, and the first branch pipes 31 located on the same floor are connected to the same first transverse pipe 32 through the first transverse connection port, and the first transverse pipes 32 located on multiple floors are respectively connected to the first vertical pipe 33 through the first longitudinal connection port. The structure of the exhaust duct 3 is used to discharge the foul air out of the room, and complete the air purification in public toilets.

[0039] In an optional embodiment, the number of the first riser 33 is multiple, and the first riser 33 is connected to at least two groups of the first transverse pipes 32 of the exhaust assembly. Specifically, when the number of floors of the building is greater than four, two first risers 33 can be set, such as the first transverse pipe 32 located on the first and second floors is connected to the first first riser 33, and the first transverse pipe 32 located on the third and fourth floors is connected to the second riser 53; when the number of floors of the building is six, ten or even more, a suitable number of first risers 33 can be set according to the actual number of floors and toilets, and the first risers 33 are respectively connected to two adjacent first transverse pipes 32. Through this structure, the exhaust work can be performed more efficiently. Furthermore, by performing the exhaust work separately through multiple first risers 33, the exhaust pressure of a single first riser 33 can be greatly reduced, and the exhaust can be dispersed to avoid the concentrated exhaust of a large amount of gas at the end of the first riser 33, which pollutes the environment.

[0040] In an optional embodiment, a fan 4 is provided in each of the first risers 33 . This structure enables efficient negative pressure exhaust to be performed in each of the first risers 33 , thereby improving the exhaust efficiency.

[0041] In an optional embodiment, the first branch pipe 31 is vertically connected to the side wall of the connecting member 2, or the first branch pipe 31 is connected to the side wall of the connecting member 2 obliquely upward toward the outside of the exhaust channel 21 to form exhaust and closed deodorization.

[0042] Specifically, since the first branch pipe 31 is located below the outlet 11 of the sanitary ware 1, when an object passes through the outlet 11, it is inevitable that a small amount of liquid will splash onto the exhaust channel 21. By vertically connecting the first branch pipe 31 to the side wall of the connector 2, or connecting the first branch pipe 31 to the side wall of the connector 2 obliquely upward toward the outside of the exhaust channel 21, it is possible to prevent objects from splashing onto the exhaust channel 21, and prevent the exhaust channel 21 from being blocked by dirt and affecting subsequent exhaust work. Furthermore, the gas usually flows upward, so this structure has a guiding effect on the flow direction of the gas, and also facilitates the fan 4 to extract the gas when a negative pressure is generated in the exhaust duct 3, thereby improving the exhaust efficiency.

[0043] In an optional embodiment, the sewage pipe 5 includes at least one second branch pipe 51, at least one second transverse pipe 52 and at least one second vertical pipe 53, the second branch pipe 51 is connected to the connecting piece 2, the second transverse pipe 52 connects the second branch pipe 51 and the second vertical pipe 53, the bottom end of the second vertical pipe 53 is connected to the septic tank 6; the bottom end of the first vertical pipe 33 is connected to the second vertical pipe 53.

[0044] The sewage pipe 5 is used to discharge sewage into the septic tank 6 . Specifically, the bottom end of the first riser 33 is connected to the second riser 53 , so that gas can also be discharged from the second riser 53 into the septic tank 6 .

[0045] In an optional embodiment, it further includes a liquid collecting pipe 8, one end of which is connected to the end of the first horizontal pipe 32 or the first vertical pipe 33, and the other end is connected to the external environment of the building, preferably connected to a septic tank.

[0046] Specifically, the other end of the liquid collecting pipe 8 is connected to the septic tank 6. Since the first branch pipe 31 is located below the discharge port 11 of the sanitary ware 1, when an object passes through the discharge port 11, it is inevitable that a small amount of liquid will splash onto the exhaust channel 21, and the atomized or vaporized liquid may flow along the exhaust pipe 3. Therefore, by arranging the liquid collecting pipe 8 at the end of the first horizontal pipe 32 or the first vertical pipe 33, and the liquid collecting pipe 8 finally leads to the external environment of the building, such as the septic tank 6, the liquid in this part can be properly discharged to avoid affecting the exhaust work of the exhaust pipe 3.

[0047] In an optional embodiment, a sealing ring 9 is provided between the discharge port 11 and the connecting member 2, and the sealing ring 9 is used to reinforce the connection between the discharge port 11 and the connecting member 2 to prevent liquid or gas from leaking from the connection between the two and causing corrosion of structural components.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
