For clarity of illustration, we choose a typical implementation for introduction; the valve and the pipeline are selected to be adapted to the most popular closestool form in the market as much as possible.

Specific embodiments are described in detail below:

the first embodiment is as follows:

first embodiment, as shown in fig. 1, the utility model relates to an overflow air exhaust interface includes exhaust main pipe 4, moisturizing end cover 1, gulp valve subassembly 2, overflow valve subassembly 3 etc..

A water supplementing end cover 1 is selected to be connected with a first air supplementing and water supplementing interface 4-1, and an air supplementing valve assembly 2 is connected with a second air supplementing and water supplementing interface 4-2; the air exhaust sealing sleeve 5 is connected with the first overflow air exhaust interface 4-3 and is opposite to the water supplementing end cover 1 up and down, and the overflow valve component 3 is connected with the second overflow air exhaust interface 4-4 and is opposite to the water supplementing valve component 2 up and down.

The exhaust interface 4-5 is transversely communicated with the first air and water supplementing interface 4-1, the second air and water supplementing interface 4-2, the first overflow air exhaust interface 4-3 and the second overflow air exhaust interface 4-4 through the exhaust main pipe 4; the first overflow air exhaust interface 4-3 is connected with an overflow pipe of the closestool through an air exhaust sealing sleeve 5 to realize the extraction of odor; after the water replenishing end cover 1 which is vertically opposite to the first overflow air exhaust interface 4-3 is connected with a water replenishing pipe, water replenishing after flushing of the closestool can be realized.

The overflow valve main body 3-1 is connected with a second overflow air exhaust interface 4-4, the overflow valve component 3 connected with the second overflow air exhaust interface extends downwards to the water tank, when water exists in the water tank, the overflow valve component 3 is below the water surface, the overflow valve plate 3-2 is in an open state, after flushing, the overflow valve plate 3-2 is in a closed state, and the air supplementing valve component 2 opposite to the upper part and the lower part of the overflow valve plate can be opened for supplementing air at the moment of flushing.

Specifically, the implementation procedure of this embodiment is as follows:

the overflow air exhaust interface 1-1 is connected through the process, the exhaust interface 4-5 is connected to the air collecting port 1-2 of the closestool exhaust deodorization device, and the first overflow air exhaust interface 4-3 is connected to the overflow pipe of the closestool through the air exhaust sealing sleeve 5.

Firstly, the overflow process is that when the exhaust deodorization device works, if water exists in a toilet water tank, the overflow valve plate 3-2 is opened around the overflow valve plate shaft 3-3 under the action of the overflow buoyancy bin 3-4, and water flows into the overflow valve main body 3-1; if the water level of the water tank is too high due to failure, the water flow can reach the exhaust interface 4-5 and flow into the overflow pipeline; as shown in fig. 4, the exhaust main pipe is integrally formed, wherein the second air and water supplementing interface is coaxial with the second overflow air exhaust interface, the first air and water supplementing interface 4-1 is coaxial with the first overflow air exhaust interface 4-3, and a central axis where the second air and water supplementing interface 4-2 and the second overflow air exhaust interface 4-4 are located is parallel to a central axis where the first air and water supplementing interface 4-1 and the first overflow air exhaust interface 4-3 are located; an included angle between the central axis where the first air and water replenishing interface 4-1 and the first overflow air extraction interface 4-3 are located and the transverse outward opening direction of the exhaust interface 4-5 along the vertical upward direction is smaller than 90 degrees; when the first overflow air exhaust interface 4-3 is in the vertical direction, one end of the exhaust interface 4-5 is tilted, so that overflow water flow is prevented from flowing to one side connected with the exhaust device, and the purpose that overflow enters the overflow pipe of the closestool is achieved.

The following describes the exhaust operation of the flushing and toilet bowl exhaust deodorizing device:

an elastic normally closed valve plate is arranged in the gulp valve assembly 2, and the valve plate is in a normally closed state through a spring. Specifically, when water in the toilet water tank enters the toilet flushing cavity instantly during flushing, the descending water body enables the flushing channel to form instant vacuum negative pressure to be transmitted to the overflow pipe, and therefore when a valve below a flushing button needs to discharge water, air is supplied through the overflow pipe; the air compensating valve assembly 2 of the utility model is normally in a closed state under the action of the spring, and the elasticity is enough to overcome the negative pressure caused by the exhaust and deodorization device, thereby ensuring that no external air leaks to influence the exhaust; when the closestool is flushed, the negative pressure is very large in the moment, the air supplementing valve component 2 can be effectively opened to supplement air in time, smooth flushing is guaranteed, and the problem that the original flushing effect of the closestool is influenced due to the addition of the exhaust device is avoided.

Meanwhile, after flushing, the water level in the water tank is lowered, the overflow valve component 3 can be suspended above the water surface, and at the moment, the overflow valve component is lowered under the action of the gravity of the overflow buoyancy bin 3-4, so that the overflow valve plate 3-2 is tilted to close the valve; the closestool exhaust deodorization device needs to work immediately after flushing to remove foul water vapor caused by flushing in the closestool cavity, and the automatic sealing of the overflow valve plate 3-2 can prevent external air from entering, so that the formation of air exhaust negative pressure is ensured.

In addition, in order to prevent the overflow valve plate 3-2 from being opened smoothly under the buoyancy action of the overflow buoyancy bin 3-4 due to negative pressure of air suction when the water level rises, the pressure relief port 3-5 of the overflow valve plate is arranged, a small amount of air enters through the pressure relief port 3-5 of the overflow valve plate, but the influence of the aperture is small, the water level can be closed after rising, water flow can enter conveniently, and the valve is opened gradually after the pressure inside and outside the valve is balanced.

Specifically, when the water level in the water tank rises to the overflow valve plate 3-2, under the action of air suction negative pressure, the overflow valve plate 3-2 cannot be opened through the action of the overflow buoyancy bin 3-4 at the first time, and water flow enters the overflow valve main body 3-1 through the overflow valve plate pressure relief opening 3-5 to keep the internal and external water pressure balanced; on the basis, water flow gradually enters along with the rise of the water level, so that after the pressure inside and outside the valve is balanced, when the valve is opened by the 3-4 buoyancy of the overflow buoyancy bin, the 3-2 overflow valve plate can be opened slowly; if the pressure relief opening 3-5 of the overflow valve plate is not arranged, under the action of suction negative pressure, the buoyancy of the overflow buoyancy bin 3-4 cannot open the overflow valve plate 3-2, and the overflow valve plate 3-2 is closed by water pressure, so that the overflow function is invalid.

The water replenishing end cover 1 is reserved with a water replenishing pipe access port outwards, and the water replenishing pipe which is originally inserted into the overflow pipe can be directly inserted into the hole reserved in the water replenishing end cover 1. The water replenishing end cover 1 provided by the utility model has two applicable apertures, which meets the requirements of connecting water replenishing pipes with different pipe diameters; when the toilet bowl water replenishing device is installed, the water replenishing end cover 1 is provided with a connector connected with a toilet bowl overflow pipe, so that the function of replenishing water in time can be realized; therefore, after each flushing, the water replenishing pipe in the water tank can replenish water into the flushing cavity of the closestool through the overflow pipe 6.

To sum up, adopt the utility model provides an overflow tonifying qi interface has both satisfied the needs of discharge foul smell, has ensured again that the existing overflow of closestool, tonifying qi and moisturizing function are not influenced.

Example two:

according to the introduction of embodiment one, connect the existing overflow moisturizing mouth of closestool the utility model provides a complete discharge foul smell function of having behind the overflow tonifying qi interface, as long as insert exhaust apparatus after, can realize effectively cleaing away of foul smell.

Another embodiment is introduced by adjusting the interface mode as follows:
