The upper part of the fan base communicates with an elbow, and the elbow is connected with the hollow air outlet pipe 32 and finally connected with the outdoor exhaust passage. The exhaust fan 33 is connected to the control switch and is powered by a power source.

The water stop device includes a water stop cavity 34, a floating ball 35 and a rubber ring 36; the float ball 35 is located inside the water stop cavity 34, and the bottom of the water stop cavity 34 has evenly distributed pores through which water can enter the water stop cavity 34 ; The rubber ring 36 is arranged at the connection between the water stop device and the fan base, and the diameter of the floating ball 35 is larger than the diameter of the rubber ring 36 . That is, the water stop cavity 34 surrounds the rubber ball and carries the floating ball 35 to prevent the floating ball 35 from falling off. The floating ball 35 can be a rubber ball or a hard plastic ball.

The rubber ring 36 can be a trapezoidal rubber ring 36 whose opening becomes smaller from bottom to top. The diameter of the floating ball 35 is larger than the minimum diameter of the trapezoidal rubber ring 36. The purpose of the rubber ring 36 is to make the floating ball 35 block when it floats on water. Hold the bottom end of the fan base to prevent water from flowing into the exhaust fan 33. The trapezoidal rubber ring 36 has a better blocking effect, and when the water stop device is not filled with water to remove odors, the float ball 35 is more likely to fall.

The sewage cavity is arranged at the bottom of the toilet seat 1, and the bottom end of the sewage cavity is provided with a sewage pipeline 4.

The upper section of the sewage pipe 4 is provided with an anti-odor device; the anti-odor device includes a fixed sleeve 41, and a sewage fixed pipe 42 is arranged at the bottom of the fixed sleeve 41 and located inside the sewage pipe 4; the bottom of the sewage fixed pipe 42 is provided with a movable cover 43 to discharge sewage A connecting block 44 is installed on the outer wall of the rear side of the fixed tube 42, a moving block 45 is installed on the rear side of the movable cover 43, and the connecting block 44 and the moving block 45 are connected by a moving shaft 46; the rear of the moving block 45 is connected with a spring cavity shell 47, reset The lower end of the spring 471 is fixed on the bottom surface of the spring cavity shell 47 , and the upper end is fixedly connected to the fixing sleeve 41 .

The surface of the return spring 471 is coated with anti-corrosion paint, and the anti-corrosion paint can be polyurethane paint or three-polyethylene anti-corrosion paint, which is convenient for construction, non-toxic, low in cost, and resistant to acid, salt, and various aqueous solutions. Try to avoid corrosion of the return spring 471.

The middle section of the sewage pipe 4 is bent upward to form an "S"-shaped structure, which has the effect of a liquid seal and prevents the air in the drain pipe from flowing back.

An anti-odor baffle 5 is arranged at the outlet of the sewage pipe 4 , and the top of the anti-odor baffle 5 is hinged at the outlet of the sewage pipe 4 . When there is water flowing through, the anti-odor baffle 5 is opened outward, so that the flowing water can pass quickly, enter the sewage pipe well 6, and finally flow into the septic tank 7; when the flowing water stops, the anti-odor baffle 5 is slowly reset due to its own weight. , used to prevent odor and odor.

A counterweight 51 is provided at the bottom of the anti-odor baffle 5 , so that it can be slowly reset when there is residual pollutants at the outlet of the sewage pipe 4 to prevent the backflow of odor.

The anti-odor baffle 5 is inclined at an angle of 60°-80° relative to the bottom of the outlet of the sewage pipe 4 . Preferably, the inclined setting angle is 75°.

The working principle of the utility model is as follows: during flushing, the water flow in the toilet impacts the movable cover 43 downward, giving the movable cover 43 a downward force, so that the movable cover 43 rotates downward with the movable shaft 46 as the axis center. The spring cavity shell 47 rotates upward with the movable shaft 46 as the axis center, so as to give the return spring 471 elastic compression, thereby forming elastic potential energy, and the water flow carries the feces into the sewage pipe 4; after the flushing is completed, the flushing force disappears , the movable cover 43 is momentarily unforced, the return spring 471 elastically resets, releases the elastic potential energy, and gives a downward force to the spring cavity shell 47, so that the spring cavity shell 47 rotates downward with the movable shaft 46 as the axis, and the movable cover 43 rotates upward with the movable shaft 46 as the axis to close the nozzle of the sewage fixing pipe 42, so as to achieve the effect of quick self-locking through the spring reset mechanism and the link mechanism.

After the person goes to the toilet or when deodorizing treatment is required, the control switch is activated to control the exhaust fan 33 of the air extraction and deodorization device to start, and the odor walks outward along the water pipe, exhaust pipe, and air extraction and deodorization device and passes through the air outlet pipe 32 It is discharged into the outdoor exhaust channel; after the person goes to the toilet, start the water pump switch, the water in the water tank 2 is flushed directly into the toilet along the water pipe all the way, and the other way along the air inlet pipe 31 impacts the float ball 35 of the water stop device , the floating ball 35 will float up tightly against the rubber ring 36 to block the bottom of the fan base, prevent water from entering the fan base, and prevent the odor from flowing back into the room; after flushing, the air entering the air inlet pipe 31 The water is flushed into the toilet along the air inlet pipe 31 and the water pipe, and enters the sewage pipe 4 together.

When there is water flowing near the outlet of the sewage pipe 4, the anti-odor baffle 5 at the outlet of the sewage pipe 4 is opened outwards, so that the flowing water can pass through quickly. When the flowing water stops, the anti-odor baffle 5 is slowly reset due to its own weight. , used to prevent odor and odor.

In the present utility model, when the toilet is not flushed, the odor is discharged into the outdoor exhaust channel along the water pipe, the exhaust pipe, the exhaust and deodorization device, and the air outlet pipe 32; when the flush button of the toilet is activated, The odor that has not been discharged from the toilet is discharged into the sewage pipe 4 along with water and the like, and finally discharged.

In the present utility model, the structure of the anti-reflection baffle 5 at the outlet of the sewage pipe 4, the structure of exhausting and deodorizing, and the self-locking structure of the anti-odor device are matched with the liquid sealing mechanism. The upper section and the exit of 4 are mechanically closed, which effectively blocks the impact of odor on the environment in the bathroom, and reduces the impact of the water quality of the liquid seal on the humidity in the bathroom, thereby avoiding excessive humidity in the bathroom.
