Description

A toilet deodorizing water sealing device

Technical field

The invention belongs to sanitary ware articles, and relates to a water sealing device for deodorizing a toilet, which can ensure that the odor cannot flow back.

Background technique

The invention of toilet seat has a history of more than 300 years so far, and its basic function is to receive and discharge sewage, but so far it has not solved the predicament of the toilet user's own inhalation of foul smell. When the toilet is in use, when the feces are discharged and have not yet fallen into the toilet tank, the heat and temperature state of its odor rises rapidly and spreads to the toilet, so that the toilet user is forced to inhale the odorous gas. In order to make the toilet not smelly when in use, there are currently three methods for eliminating the bad smell: 1. The bad smell is discharged from the toilet with a pipeline; 2. The bad smell is decomposed by chemical methods; 3. The bad smell is discharged into the sewer, preferably The most scientific method is to discharge the odor into the sewer. The method is to inhale the odor into the sewage sewer. This method is relatively easy, but it must be ensured that the odor and the methane gas in the sewer cannot flow back into the toilet under any circumstances. Technology is not easy. There are not many similar technologies and products so far, but there is another method with a simpler and more reliable structure.

Invention patent content

The invention provides a toilet deodorizing water seal device with simple and reliable structure, which can be matched with various toilets. The device can discharge the odor generated when going to the toilet into the deodorization device in the sewer through the toilet drain pipe, bypass the S trap of the toilet, enter the sewage outlet of the toilet, and discharge it into the sewer pipe. Under the condition of negative pressure siphon generated by flushing water, it can completely not affect the toilet flushing and water-saving functions, and can ensure that the methane gas in the sewer will not flow back into the toilet under any circumstances.

A toilet deodorizing water seal device of the present invention is installed in the toilet water tank and consists of three major components: an electric exhaust fan, a water seal tank, and a water seal cover; the electric exhaust fan is connected to the water seal tank by a U-shaped pipe , the water seal tank is provided with a water seal cover, and the water seal tank is connected to the sewage pipe of the toilet through the water tank through the exhaust pipe. The electric exhaust fan is set above the water surface of the overflow port of the drain valve in the water tank. The air outlet of the electric exhaust fan is connected to the U-shaped pipe on the water seal tank, and the other outlet of the U-shaped pipe penetrates into the water seal tank to reach the water seal. In the middle of the tank, the cavity diameter of the water-sealed tank is larger than the outer diameter of the U-shaped tube. The U-shaped tube and the water-sealed tank are coaxial and concentric to form an annular water cup with a cavity around it. There is an overflow port on the side wall of the middle of the water-sealed tank. The bottom of the orifice is lower than the exhaust outlet of the U-shaped pipe, and the overflow port is connected with a 7-type exhaust pipe. The lumen diameter of the 7-type exhaust pipe is equal to the lumen diameter of the U-shaped pipe. and fixed on the bottom of the water tank of the toilet. The mouth of the 7-type exhaust pipe has a hose connected with the S water trap of the toilet. The other end of the U-shaped water supply pipe is connected to the water supply port of the water inlet valve to form a water seal tank assembly. The middle of the water seal tank has a water seal cover with a large bottom and a small top. The opening of the water seal cover faces downward and covers the exhaust outlet of the U-shaped pipe. The mouth of the water seal cover is immersed in the ring-shaped water cup of the water seal tank. The outer diameter of the U-shaped pipe is equal to that of the U-shaped pipe.

The top of the water seal cover is integrated with the water storage cup to form a water seal cover assembly; there is a discharge hole at the bottom of the water storage cup, the mass of the water seal cover and the water storage cup is slightly larger than the mass of water, and the maximum outer diameter of both is slightly smaller than the water seal tank The inner diameter of the cavity ensures that the water seal cover and the water storage cup can move freely up and down. The present invention is achieved through the following technical solutions:

In the present invention, the device is installed in the water tank of the toilet, and the odor in the toilet is sucked into the water tank by using an electric exhaust fan, and then the water seal cover is blown away from the water surface by air pressure through the exhaust outlet of the U-shaped pipe to generate Gas passage, the odor is discharged into the 7-type exhaust pipe from the overflow port, discharged into the S trap of the toilet along the hose, and discharged into the sewer from the sewage outlet. When the electric exhaust fan is powered off, the U-shaped pipe loses air pressure, and the water seal cover falls into the water to form a water seal. At the same time, the water flow through the U-shaped water supply pipe flows into the water seal cover by using the water supply valve when the water enters. The water storage cup on the top, the water storage cup will be filled with water, use the water storage gravity in the water storage cup to press the water seal cover and the U-shaped pipe exhaust outlet to fit, when the negative pressure siphon phenomenon occurs when the toilet is drained, the water seal tank will At the same time, a negative pressure phenomenon is generated. The water seal cover is not sucked up by the negative pressure due to the gravity of the water, which ensures the sewage siphon function of the toilet, ensures the replacement rate of the toilet sewage, stops the water supply of the water inlet valve, and no longer has the water storage cup. When new water flows in, the water in the water storage cup will gradually flow out from the discharge hole, and at the same time, the water in the water storage cup will be replaced out of the water storage cup. At this time, the water seal cover will no longer have the gravity pressure of water, waiting for the next use .

detailed description

The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

Now in conjunction with Fig. 1, Fig. 2 the present invention is further described. A toilet deodorizing water sealing device of the present invention is installed in the toilet water tank 19, and the electric exhaust fan 1 is set above the water surface of the water tank drain valve overflow port 20 in the water tank 19, and the 7-type exhaust The pipe 6 passes through the bottom of the toilet water tank 19 and is fixed with the water tank 19. The mouth of the 7-type exhaust pipe 6 has a flexible pipe 7 which communicates with the toilet S water trap 8, and the top cover of the water seal tank 9 is provided with The water supply port 10 is connected with a U-shaped water supply pipe 11, and the other end of the U-shaped water supply pipe 11 is connected with the water supply port 12 of the water inlet valve. When the device was in standby mode, the water seal cover 13 could freely drop into the water storage cup 15 with its own quality slightly greater than that of water, until the water seal cover 13 fits with the U-shaped pipe exhaust outlet 14. At this time, the draft height of the water seal cover 13 and the water storage height of the U-shaped water replenishment pipe 11 are higher than the water seal height of the toilet S trap pipe 8 . A complete annular water seal area is formed between the U-shaped pipe exhaust outlet 14 and the water seal tank 3. The water in the U-shaped water supply pipe 11 cannot be discharged and forms a water seal, so it can effectively prevent the sewer gas from being discharged through the toilet. Pipe, flexible pipe 7, 7 type exhaust pipes 6 enter water seal tank 3, flow in the toilet.

Now in conjunction with Fig. 3, the present invention is further described. When the user gives the start function, the electric exhaust fan 1 starts, the gas of the toilet bowl 17 is sucked into the water tank 19 through the annular drain groove 18, and the gas is discharged into the U-shaped pipe 2 by the electric exhaust fan 1. At this time, the water storage cup 15 does not store water, and there is no gravity on the water seal cover 13. Due to the gas pressure produced by the electric exhaust fan 1, the water seal cover 13 can be blown away from the water surface and stay on the upper end of the water seal tank 3 cavity. U-shaped pipe exhaust outlet 14 enters water seal tank 3, discharges into toilet S trap pipe 8 from 7-type exhaust pipe 6 along flexible pipe 7, and discharges into sewer from sewage outlet.

Now in conjunction with Fig. 4, the present invention is further described. At this time, the electric exhaust fan 1 runs all the time, exhausting air continuously until the drain valve drains water. At this time, the water level of the water tank 19 drops, the water inlet valve is opened, and the water is discharged from the water replenishment port 12 of the water inlet valve, and flows into the water seal through the U-shaped water replenishment pipe 11. The water supply port 10 on the tank top cover 9 flows into the water storage cup 15, and due to the large amount of incoming water, the water storage cup 15 is quickly filled, and the excess water overflows the water storage cup 15 and flows into the annular water cup 4 of the water seal tank 3, and the original storage Water and excess water flow into the 7-type exhaust pipe 6 through the overflow port 5, discharge into the toilet S trap 8 along the flexible pipe 7, and discharge into the sewer from the sewage outlet. Since the U-shaped pipe exhaust outlet 14 is higher than the overflow port 5, it is ensured that water cannot flow into the U-shaped pipe 2 from the U-shaped pipe exhaust outlet 14 at any time. At this time, because the gravity of the water stored in the water storage cup 15 overcomes the air pressure of the electric exhaust fan 1, the water storage cup 15 and the water seal cover 13 fall into the annular water cup 4 to form a water seal. Fan 1 stops working. At this moment, the toilet drainage sewer produces negative pressure suction. Due to the height of the water seal and the gravity of the water storage cup 15, the water seal passage cannot be opened, which ensures the siphon function of the toilet. When the water inlet valve is put in place, the water inlet stops, and the water replenishment also stops. At this moment, the water in the water storage cup 15 slowly flows out through the discharge hole 16 at the bottom of the water storage cup 15 cups, recovers the initial state, and waits for the next use.
