Description

Technical Field

[0001] This utility model relates to a vented toilet. Background Technology

[0002] Traditional bathroom odor removal primarily relies on independent exhaust fans installed in the ceiling. When the toilet is used, odors first diffuse from inside the toilet bowl into the bathroom space, and then are expelled outdoors by the ceiling exhaust fan. This ventilation method has significant drawbacks:

[0003] 1) Odor retention problem: Odors need to pass through the human breathing area and the entire bathroom space before they can be expelled, which inevitably leads to human contact with odors and affects the user experience; 2) Low emission efficiency: Even with a high-power exhaust fan, it is difficult to completely remove odors that have spread into the air, especially when the odor concentration is high. Utility Model Content

[0004] This utility model provides a vented toilet that can effectively solve the above problems.

[0005] This utility model is implemented as follows:

[0006] A ventilated toilet, including

[0007] Toilet body;

[0008] Back seat;

[0009] Seat ring; a hollow cylinder disposed within the seat ring; an abutment disposed on the outer wall of the hollow cylinder;

[0010] A bucket lid, with a hinged structure for connecting the seat ring and the bucket lid;

[0011] An air intake assembly, detachably installed within the toilet seat, is used to expel odors from inside the toilet bowl; the air intake assembly includes:

[0012] The upper ring has an edge protrusion at its top that engages with the seat ring, and an annular groove is formed between the edge protrusions;

[0013] The middle ring component has air pipes symmetrically arranged on its inner wall and an external exhaust pipe on its outer wall.

[0014] A bottom ring is used to contact the surface of the toilet body, thereby isolating the suction assembly from the toilet body;

[0015] The annular groove is provided with a snap-fit ​​structure that cooperates with the abutment to fix the air intake assembly, and the external exhaust pipe is connected to an external negative pressure device.

[0016] The beneficial effects of this utility model are:

[0017] (1) This utility model integrates a detachable suction component 70 inside the toilet seat ring 30. It utilizes the cooperation between the abutment of the outer wall of the hollow cylinder 300 and the snap-fit ​​structure in the annular groove to achieve quick disassembly and assembly. The symmetrically arranged air pipes, in conjunction with the external negative pressure equipment, form a directional airflow channel, which can directly suck and discharge the odor from inside the toilet before it diffuses, thereby ensuring the odor is discharged. At the same time, the modular design facilitates cleaning and maintenance, solving the technical problems of poor exhaust effect and complex structure that are difficult to disassemble in the prior art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] Example 1

[0034] Reference Figure 1-5 As shown, a venting toilet includes...

[0035] Toilet body 10; back seat 20.

[0036] A seat ring 30; a hollow cylinder 300 disposed within the seat ring 30; and an abutment member disposed on the outer wall of the hollow cylinder 300. The abutment member includes a side cylinder 302, a movable rod 304 movably disposed inside the side cylinder 302, abutment ends 306 and limiting ends 310 respectively disposed at both ends of the movable rod 304, and a spring 308 sleeved on the movable rod 304. The side cylinder 302 is connected to the hollow cylinder 300, thereby allowing the movable rod 304 and the abutment ends 306 to extend into the hollow cylinder 300. The snap-fit ​​structure 710 includes a base plate 71 fixed in an annular groove. 00; A first rod 7102 is vertically mounted on the base plate 7100; A second rod 7104 is connected to the first rod 7102, and its free end is provided with a fastening end 7110; A limiting ring 7108 and an annular member 7106 are sleeved on the second rod 7104; When the abutting end 306 extends into the hollow cylinder 300, it pushes the fastening end 7110 down and locks it with the abutting end 306; After the second rod 7104 extends into the hollow cylinder 300, the abutting end 306 slides under the fastening end 7110, thereby connecting the seat ring 30 with the suction assembly 70.

[0037] Locking process: When the seat ring 30 is pressed down, the abutment end 306 contacts the inclined surface of the latching end 7110, pushing the movable rod 304 to retract. After the abutment end 306 passes the apex of the latching end 7110, the spring 308 rebounds and locks it under the latching end 7110, forming a mechanical interlock. When disassembling, the seat ring 30 needs to be manually pressed down. The abutment end 306 falls to the bottom of the ring 7106 using the inclined surface of the ring 7106. Then, the seat ring 30 is lifted up, and the abutment end 306 drives the ring 7106 to move upward. The abutment end 306 can then directly pass over the lower end face of the latching end 7110, thereby releasing the self-locking.

[0038] Bucket lid 40, hinge structure 60 for connecting seat ring 30 and bucket lid 40.

[0039] The suction assembly 70 is detachably installed inside the seat ring 30 to expel odors from inside the toilet. The suction assembly 70 includes: an upper ring 700, the top of which has an edge protrusion 702 that engages with the seat ring 30, and an annular groove formed between the edge protrusions 702. The inner walls of the two edge protrusions 702 are alternately provided with a plurality of engaging protrusions 708 that connect to the toilet lid 40 (which engage with engaging parts provided on the toilet lid 40, not shown in this application, but are common engaging structures in the prior art, so they will not be described in detail here); a middle ring 712, the inner wall of which has symmetrically provided air pipes 704, and the outer wall has provided an external exhaust pipe 706; and a bottom ring 714, which is used to contact the surface of the toilet body 10 to isolate the suction assembly 70 from the toilet body 10. The annular groove has an engaging structure 710 that engages with an abutment to fix the suction assembly 70, and the external exhaust pipe 706 is connected to an external negative pressure device.

[0040] The 704 air inlet features a flared design (expansion angle of approximately 20°) and a built-in 40-mesh stainless steel filter, ensuring waterproofing at a 30° angle while reducing airflow resistance.

[0041] The outer diameter of the bottom ring 714 is larger than that of the middle ring 712, and the limiting ring 7108 is made of elastic rubber. The limiting ring 7108 is an openable magnetic snap ring, which can restrict the snap-fit ​​end 7110 and prevent the lid 40 from separating from the suction component 70 under force.

[0042] The central ring 712 has several strip-shaped air intake ports 7120. The diameter of the strip-shaped air intake ports 7120 is 1-2mm, which directly sucks up the gas escaping from the toilet (this principle utilizes the Bernoulli effect, when a high-speed airflow passes through the main channel, a low-pressure zone is formed in the secondary channel to assist in air intake).

[0043] The air inlet of the trachea 704 is tilted upwards at an angle of 15° to 45°. In one embodiment, the air inlet of the trachea 704 is designed to tilt upwards at approximately 30° (preferred angle), with its inlet end having a flared shape (expansion angle of approximately 20°). The inner wall is machined with a spiral guide groove approximately 0.5 mm deep (lead 30 mm), and the port is covered with a 40-mesh stainless steel filter. This tilt angle has been verified through fluid simulation. In the waterproof test, it can completely block water splashes during a 1 L / s flow rate flush (splash volume < 0.1 ml / time), while maintaining an airflow speed of 1.2 m / s (airflow loss of only 8%). Compared to the approximately 15° design, it reduces the probability of foreign matter accumulation by 50%, and compared to the approximately 45° design, it reduces airflow noise by approximately 15%. The tilted structure is integrally formed by injection molding, with an additional approximately 2 mm reinforcing rib at the root to prevent deformation. The overall structure has a smooth transition with the inner wall of the middle ring 712, ensuring an odor capture rate of approximately 88%.

[0044] This case further includes a suction step for a vented toilet, the steps of which are as follows:

[0045] S1. Equipment pre-start preparation

[0046] Connect the external exhaust duct (706) to the fan inlet via a quick-connect interface, and connect the fan outlet to the purifier via a flexible hose (an activated carbon + photocatalytic composite purification module is recommended). Then, confirm that the fan (12VDC) and purifier (220VAC) are powered normally, and test the infrared sensor or pressure switch (such as the toilet seat opening and closing trigger signal).

[0047] S2, Inhalation Trigger Phase

[0048] Signal detection (choose one)

[0049] Option A: When the bucket lid (40) opens at an angle greater than 15°, the Hall sensor sends a start signal; Option B: When the pressure sensor detects that the seat ring (30) is under pressure (greater than 5 kg), the system is activated; After selecting one option, the fan is soft-started and runs at 50% power (about 4 CFM) for the first 3 seconds to avoid airflow impact noise;

[0050] S3, Odor Capture and Transport

[0051] Main airflow path: Odor → Air pipe 704 (30° inclined spiral acceleration) → Middle ring component 712 cavity → Exhaust pipe 70. When the main air pipe flow rate is >6L / s, the strip gap 7120 automatically replenishes air (anti-siphon effect). At the same time, it adjusts according to the toilet usage status: Normal mode: 1.2m / s (silent mode), after flushing: 2.0m / s (pressure boost mode, lasts for 30 seconds).

[0052] S4. Purification Treatment Stage

[0053] After passing through the fan, the odor first passes through a stainless steel filter (intercepting particles >50μm), then an activated carbon layer (iodine value ≥1000) adsorbs hydrogen sulfide / ammonia, and a UV photocatalytic module (275nm wavelength) decomposes VOCs. Finally, an electrochemical sensor (such as MQ-135) is installed at the purifier outlet to trigger an alarm when the standard is exceeded.

[0054] S5, System Shutdown and Maintenance

[0055] After the lid is closed, delay for 10 seconds before closing (to expel any remaining gas).

[0056] Working principle: When a user uses the toilet, the external negative pressure device is activated and generates suction through the external exhaust pipe 706. The odor generated inside the toilet bowl is first rapidly drawn in through the strip-shaped air intake 7120 on the central ring 712 and the upwardly inclined air pipe 704 (15°-45°). The odor flows through the internal cavity of the central ring 712 and is discharged through the external exhaust pipe 706. Simultaneously, the suction assembly 70 is securely installed through the abutment and locking structure 710 composed of the side cylinder 302, the movable rod 304, and the spring 308. The movable rod 304 is activated by the spring 308. The downward-pushing contact end 306 extends into the hollow cylinder 300 and forms a mechanical lock with the snap-fit ​​end 7110. Together with the large outer diameter design of the bottom ring 714, it forms a sealed cover on the edge of the toilet body 10. The seat ring 30 and the hollow cylinder 300 constitute the main airflow channel. The snap-fit ​​protrusion 708 on the edge protrusion 702 ensures the sealing performance when the lid 40 is closed. The hinge structure 60 maintains normal use function. All components work together to achieve the instant emission effect of odor being drawn away as soon as it is generated, completely avoiding the defect of odor first diffusing into the bathroom space and then being discharged in the traditional exhaust method.

[0057] Example 2

[0058] Reference Figure 6 As shown, the difference from Embodiment 1 is that it includes an air inlet 80 disposed inside the toilet body 10, an exhaust pipe 120 connected to the air inlet 80, an exhaust device 100 and a purification device 110 connected to the exhaust pipe 120; it also includes a decorative panel 90 for blocking the exhaust device 100, the purification device 110 and the exhaust pipe 120.

[0059] The above embodiment directly sets an air inlet 80 inside the toilet and connects it directly to the air inlet 80 through an exhaust pipe 120. This allows the exhaust to be purified and discharged through the exhaust device 100 and the purification device 110, making it faster in actual implementation.

[0060] Furthermore, a waterproof structure is installed at the air inlet 80 to prevent water from directly entering the air inlet 80 when the toilet is flushed, thus improving the permeability of the air inlet 80. In addition, the air inlet 80 can be bent downwards to prevent urine or excrement from falling into the air inlet 80 when people are using the toilet.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
