Abstract
Description
Technical Field
[0001] This utility model relates to a toilet deodorization system. Background Technology
[0002] The odor people smell when defecating is mainly due to substances like indole, skatole, hydrogen sulfide, and volatile fatty acids found in feces. Smart toilets typically use a fan to draw the odor into a duct, where it is filtered through materials like activated carbon and diatomaceous earth before being released back into the air. However, this method of deodorizing by filtering the air has several problems: First, it's incomplete and cannot completely eliminate the odor. Many filter materials can only filter one or two types of odors, not all of them simultaneously. The filtered odor is then released back into the air, causing secondary air pollution. Second, it requires significant consumables. Deodorizing materials are generally consumables that need to be replaced over time, leading to high costs, frequent replacements, and inconvenience. Utility Model Content
[0003] This utility model provides a toilet odor deodorization system, which overcomes the shortcomings of the prior art. The technical solution adopted by this utility model to solve its technical problem is as follows:
[0004] A toilet odor control system includes a flushing inlet pipe for directing water from the tank to the basin cavity, a flushing drain pipe for directing waste from the basin cavity to a sewage drain pipe, a fan for sucking up odors from the basin cavity, and an exhaust pipe for discharging the odors. The exhaust end of the fan is connected to the inlet end of the exhaust pipe, and the inlet end of the fan is connected to the flushing inlet pipe. A bend is connected to the wall of the flushing drain pipe, and the exhaust end of the exhaust pipe extends into the bend through the inlet of the bend. And beyond the inflection point of the bend, the outlet of the bend is connected to the sewage pipe, and also includes a water supply pipe, which is connected between the bend and the inlet valve or between the bend and the flushing inlet pipe so that when the inlet valve or the flushing inlet pipe is filled with water, a portion of the water can be introduced into the inflection point of the bend to block the gas on both sides of the bend inlet and outlet. After the fan is started, it travels along the basin, the flushing inlet pipe, the exhaust pipe, and the bend to the sewage pipe to form an odor exhaust path.
[0005] In a preferred embodiment: the bend is connected to the outer wall of the flushing drain pipe.
[0006] In a preferred embodiment: the bend is C-shaped and surrounds the flushing drain pipe, with the inlet and outlet facing upwards.
[0007] In a preferred embodiment, the bend is U-shaped or S-shaped and is connected to the top of the flushing drain pipe.
[0008] In a preferred embodiment: the exhaust pipe's outlet end is located away from the bend outlet.
[0009] In a preferred embodiment: the air inlet end of the exhaust pipe is connected to the flushing water inlet pipe at the portion of the flushing water inlet pipe near the water tank.
[0010] In a preferred embodiment, the water supply pipe is connected to the bend at the inlet side of the bend.
[0011] In a preferred embodiment: the flushing inlet pipe includes a vertical portion and a horizontal portion, and the water supply pipe is connected to the vertical portion of the flushing inlet pipe.
[0012] In a preferred embodiment: the inner wall of the flushing inlet pipe is provided with a water groove below the location where the water supply pipe is connected.
[0013] In a preferred embodiment: the water groove is arranged in a complete circle along the inner wall of the flushing inlet pipe in the circumferential direction.
[0014] Compared with the prior art, this technical solution has the following advantages:
[0015] 1. The odor is discharged directly into the sewage pipe without filtration. The bend in the pipe uses a water seal to prevent the odor from flowing back into the sewage pipe, thus completely eliminating the odor.
[0016] 2. When the inlet valve is opened to replenish the water tank, or when the drain valve of the water tank is opened to flush, some water will flow into the bend through the water supply pipe, thus ensuring that the water at the bend will not dry up. Even if the toilet is not used for a long time, the gas on both sides of the bend inlet and outlet can still be effectively blocked, and the odor in the sewage pipe will not flow back due to the failure of the water seal.

[0021] Figure 4 A schematic diagram of another structural variation of the toilet odor-eliminating system is shown. Detailed Implementation
[0022] Please refer to Figure 1 and Figure 2A toilet deodorization system for removing odors from a toilet includes a flushing inlet pipe 20 for directing water from a tank 10 to a basin cavity 30, a flushing drain pipe 40 for directing waste from the basin cavity 30 to a drain pipe 50, a blower 60 for sucking up odors from the basin cavity 30, and an exhaust pipe 70 for discharging odors. The exhaust end of the blower 60 is connected to the inlet end of the exhaust pipe 70, and the inlet end of the blower 60 is connected to the flushing inlet pipe 20. Therefore, after using the toilet, the drain valve opens the tank 10, and water from the tank enters the basin cavity 30 along the flushing inlet pipe 20. Waste in the basin cavity 30 is then flushed into the flushing drain pipe 40 and finally flows into the drain pipe 50. Under the action of the blower 60, odors from the basin cavity 30 are sucked in along the flushing inlet pipe 20 and then discharged into the drain pipe 50 through the exhaust pipe 70. The pelvic cavity 30 flushes waste into the sewage pipe 50 via the flushing drain pipe 40, hence it is also known as a wall-mounted toilet. A bend 80 is connected to the wall of the flushing drain pipe 40. The bend 80 has an inflection point that blocks airflow on both sides after water is filled, such as the bend of an S-bend that acts as a water seal. The exhaust pipe 70 extends from the inlet of the bend 80 into the bend and beyond its inflection point; the outlet of the bend 80 connects to the sewage pipe 50. It also includes a water supply pipe 90, which is connected between the bend 80 and the inlet valve 100 so that when the inlet valve 100 is filled with water, a portion of the water can be introduced into the bend 80 to block the gas on both sides of the inlet and outlet of the bend. At the same time, the outlet of the exhaust pipe 70 is located below the liquid level inside the bend 80. After the fan 60 is started, it forms an odor exhaust path along the basin 30, the flushing inlet pipe 20, the exhaust pipe 70, and the bend 80 to the sewage pipe 50.
[0023] Therefore, during daily use, when the water in the water tank 10 is insufficient, the inlet valve 100 automatically opens to replenish the water tank 10. Most of the water output by the inlet valve 100 directly enters the water tank, and a very small portion is added to the bend 80 through the replenishment pipe 90, thereby ensuring the water seal effect at the bend 80. When the fan 60 is running, the odor in the basin 30 is drawn in and flushes the inlet pipe 20, and then discharged into the exhaust pipe 70. After being output from the outlet end of the exhaust pipe 70, it forms bubbles in the water in the bend 80 and rises rapidly. After emerging from the water surface, it flows into the drain pipe 50.
[0024] Preferably, the bend 80 is connected to the outer wall of the flushing drain pipe 40, making the assembly of the bend more convenient.
[0025] Preferably, the bend 80 is C-shaped, surrounding the flush drain 40 water pipe, with the inlet and outlet facing upwards.
[0026] Preferably, the outlet end of the exhaust pipe 70 is far from the outlet of the bend 80. That is, as long as the outlet end of the exhaust pipe 70 is beyond the inflection point of the bend, it can be ensured that the gas can only rise forward after exiting the exhaust pipe 70 and will not flow back. At the same time, being far from the outlet of the bend 80 can better prevent water in the bend from being blown out.
[0027] Preferably, the air inlet end of the exhaust pipe 70 is connected to the flushing water inlet pipe 20 at the portion of the flushing water inlet pipe 20 near the water tank 10.
[0028] Preferably, the water supply pipe 90 is connected to the bend pipe 80 at the inlet side of the bend pipe 80.
[0029] Combination Figure 3 As shown, in a modified embodiment of the toilet odor control system, the connection position of the water supply pipe is changed. The water supply pipe 90 is connected between the bend 80 and the flushing inlet pipe 20. Thus, when the tank 10 drains, most of the water enters the basin cavity 30, but a small portion of the water will enter the bend 80 through the water supply pipe 90, achieving automatic water replenishment to the bend 80 during daily use. Preferably, the flushing inlet pipe 20 includes a vertical portion and a horizontal portion, with the water supply pipe 80 connecting to the vertical portion. Preferably, the inner wall of the flushing inlet pipe 20 has a water groove 22 below the connection point of the water supply pipe 90. More preferably, the water groove 22 is arranged in a complete circumference along the inner wall of the flushing inlet pipe, collecting water flow from the inner wall of the flushing inlet pipe 20 and allowing water to enter the water supply pipe 90 more effectively.
[0030] Combination Figure 4 As shown, as another structural variation of the toilet odor control system, the shape of the bend is changed. The bend 80 is U-shaped and connected to the top of the flushing drain pipe 20. Understandably, the specific shape of the bend 80 is not limited, as long as it has an inflection point that can block the flow of gas at both ends after water is filled, thus preventing the backflow of gas at the end.
[0031] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
