Referring to fig. 2 to 4, as an embodiment of the present utility model, there is provided a gas-water separation device for a toilet, including a gas-water separation joint 3 provided between a toilet body 1 and a drain pipe 2. The gas-water separation joint 3 has a plurality of ports, a first port 31 is used for connecting with the waterway 13 of the toilet body 1, a second port 32 is used for connecting with the drain pipe 2, and a third port 33 is used for connecting with the deodorizing device 4. A drainage channel is formed between the first interface 31 and the second interface 32, tap water enters the sewage disposal cavity 12 of the toilet body 1 from the drainage pipe 2 sequentially through the drainage channel and the waterway channel 13, an exhaust channel is formed between the first interface 31 and the third interface, odor of the sewage disposal cavity 12 enters the deodorizing device 4 sequentially through the waterway channel 13 and the exhaust channel, and the drainage channel and the exhaust channel have a small section of common channel. The gas-water separation joint 3 is Y-shaped, the drainage channel is linear, and is preferably vertical, tap water can enter the toilet body through the drainage channel quickly, flushing of the sewage draining cavity is facilitated, the exhaust channel extends out of the side face of the drainage channel, and during flushing, fast flowing water can flush odor to the side face, so that the exhaust channel is arranged on the side face of the drainage channel, and the odor is discharged during flushing. Both the water path 11 of the toilet and the path of the gas-water separation joint are used for odor discharge when not flushing.

The gas-water separation joint can be installed in the water tank or on the drain pipe, and two installation modes and use occasions will be described below.

Example 1

Referring to fig. 5, the gas-water separation joint is installed in the water tank. The water tank 5 is usually provided with a drain valve 6 and an overflow pipe 7, the drain pipe 2 supplies tap water to the water tank 5, the water tank maintains a certain water level, when flushing is needed, the drain valve 6 is opened, and the tap water in the water tank enters the sewage draining cavity 12 through the water outlet of the water tank and the waterway channel 11 to flush the toilet. The construction and operation of the tank 5 and its internal drain valve 6 and overflow pipe 7 are known in the art and will not be described in detail here.

The gas-water separation joint 3 is arranged at the water outlet of the water tank 5, the first joint 31 is positioned below the water tank and communicated with the waterway 11 of the toilet, the second joint 32 is connected with the water outlet of the drain valve 6, and the third joint 33 is connected with the deodorizing device 4. The gas-water separation joint 3 also has a fourth connection 34, the fourth connection 34 being intended to be connected to the overflow pipe 7, an overflow channel being formed between the first connection 31 and the fourth connection 34. The deodorizing device 4 is provided with a fan or the like, and the odor is drawn from the sewage chamber 12 into the deodorizing device through the first port 31 and the third port 33.

Because the upper end of the overflow pipe 7 is provided with an opening, when the deodorizing device 4 works, gas in the water tank is pumped into the deodorizing device 4 from the opening at the upper end of the overflow pipe 7, and the distance from the sewage discharging cavity 12 to the deodorizing device 4 is far, and the channel is more tortuous, so that the pumping of the deodorizing device 4 from the sewage discharging cavity 12 can be influenced by the opened overflow pipe 7. In order to reduce the influence of the overflow pipe 7 and maintain the deodorizing effect, an upper cover 71 is provided on the top end of the overflow pipe 7 to close the top opening of the overflow pipe. However, the closed overflow pipe 7 loses its overflow function, and a bent pipe 8 is provided at one side of the overflow pipe 7 in order to restore its overflow function. The upper end of the elbow pipe 8 is connected with the upper cover 71, and the lower end extends into the water tank, so that the water tank is communicated with the overflow pipe, and water in the water tank can enter the overflow pipe through the elbow pipe. The height of the overflow pipe 7 is unchanged, the upper end of the bent pipe 8 is communicated with the overflow pipe, and the lower end is lower than the height of the overflow pipe 7, so that the overflow height of the water tank is unchanged. The opening at the top end of the overflow pipe 7 is closed by the upper cover 71, when the water tank is filled with water, the lower end of the bent pipe 8 is soaked in the water, and the deodorizing device cannot extract the gas in the water tank from the overflow pipe, so that the deodorizing effect can be maintained.

When the drain valve is opened for flushing, the water level in the water tank is lowered to enable the lower end of the bent pipe 8 to be higher than the water surface, at the moment, the lower end of the bent pipe 8 is in contact with air, and the deodorizing device can extract air in the water tank from the opening of the lower end of the bent pipe 8. To avoid this, an arc-shaped bend is provided between the upper and lower ends of the bent pipe 8 so that a trap 81 is formed at the bent pipe, and when the water level in the water tank drops, water stored in the trap forms a water seal, thereby isolating the overflow pipe 7 from the air of the water tank, and the deodorizing means extracts the air in the water tank when the water level in the water tank drops is avoided. It should be noted that in order to ensure the overflow effect of the overflow pipe 7, the diameter of the elbow is greater than the diameter of the inlet pipe 72 at the top of the overflow pipe.

The installation mode of the gas-water separation device in the water tank is suitable for various toilets or squatting pans or urinals with water tanks, the gas-water separation device can be installed only by enough space in the water tank, the connection mode of the gas-water separation joint and the water tank is the same as the connection mode between the drain valve and the water tank, and the gas-water separation device can be easily realized by a person skilled in the art, and the gas-water separation device is not described in detail herein. In order to reduce the impact on the cistern and the toilet bowl flushing, it is possible to retrofit existing drain valves by replacing the connection of the drain valve for connection to the cistern below the valve for opening and closing the cistern with the gas-water connection according to the utility model and by mounting the overflow pipe fixed to the drain valve on the gas-water connection. In other embodiments, it is also possible to add a gas-water separation joint directly between the drain valve and the water tank. The deodorizing means may be a gas treatment means installed in the water tank or may be an exhaust pipe directly connected to the outside.

As shown in fig. 8, the drain passage of the air-water separation joint 3 and the water passage of the toilet body are filled with water during flushing, so that odor cannot be discharged from the water passage to the air-water separation joint 3 during flushing. To overcome this problem, a sandwich tube 21 is provided at the first junction 31, the sandwich tube 21 having two layers of pipes which are not in communication with each other, the inner pipe of which is used for drainage and the outer pipe of which is used for odor removal. Referring to fig. 9, when not flushing, the inner and outer layers of the sandwich tube are used for exhausting odor because the water in the pipeline is absent. This makes it possible to keep the exhaust gas uninterrupted and to sufficiently deodorize.

Example two

Referring to fig. 6 and 7, the gas-water separation joint is installed on the drain pipe between the water tank and the squatting pan. The first port 31 of the gas-water separation joint 3 is communicated with the waterway 11 of the toilet, the second port 32 is communicated with the water supply end of the drain pipe 2, and the third port 33 is communicated with the exhaust pipe 9. The exhaust pipe 9 may be connected to the deodorizing means or may be connected to an external exhaust pipe.

Referring to fig. 8, during flushing, since the drain pipe 2 is filled with water, odor cannot be discharged from the drain pipe to the gas-water separation joint 3 during flushing. To overcome this problem, a sandwich tube 21 is provided at the first junction 31, the sandwich tube 21 having two layers of pipes which are not in communication with each other, the inner pipe of which is used for drainage and the outer pipe of which is used for odor removal. Referring to fig. 9, when not flushing, the inner and outer layers of the sandwich tube are used for exhausting odor because the water in the pipeline is absent. This makes it possible to keep the exhaust gas uninterrupted and to sufficiently deodorize. In other embodiments, the drain pipe 2 between the gas-water separation joint 3 and the toilet body 1 is provided as the central pipe 21, so that the gas water pipeline between the gas-water separation joint 3 and the toilet body 1 can be completely separated, and odor emission during flushing can be further promoted.

The installation mode of the gas-water separation device on the drain pipe is suitable for a toilet with a small water tank space and inconvenient installation or without a water tank, and the toilet can be a toilet or a urinal besides the squatting pan shown in fig. 6 and 7.

In summary, according to the different installation modes, the gas-water separation device comprises a gas-water separation joint, an overflow pipe, an upper cover, a bent pipe and a sandwich pipe, wherein the overflow pipe, the upper cover, the bent pipe and the sandwich pipe are selected according to the requirement.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
