technical field

The utility model belongs to the technical field of sanitary ware, in particular to a quick-drainage device for a defecator.

Background technique

Now, for squatting toilets and toilets with built-in water traps or siphon devices, after the flushing is completed, there is a water seal in the water traps that come with the toilet, so that the sewage from the sewer will not invade the room at all. popular. However, in practice, many residents can also hear complaints, saying that the water is too slow, it is blocked again, and so on. This is because most buildings have built a U-shaped trap in the sewer below the urinal. If the user installs a toilet with its own trap on it, two traps, the upper and lower, will be formed. When the trap generates siphon to drain downward, the lower trap has not yet produced siphon, and the air cushion between the two traps will hinder the falling water flow. After the drainage flows into the second trap, it will exceed After the siphon water level is high, the secondary siphon will be generated, that is, the complete siphon of the full drainage section will be formed. This phenomenon makes the overall drainage process of the toilet not smooth. Due to the hysteresis of the siphon of the lower trap and the obstruction of the drainage of the upper trap, it may also cause dirt to accumulate between the two traps, and it is difficult to clean and discharge.

The traditional solution is to significantly raise the height of the toilet and increase the amount of flushing water to increase the potential energy of drainage and complete the sewage discharge. However, due to the limitation of the ground height, it is difficult to install the height of the toilet, especially many squatting toilets also have the function of a floor drain. The location is inconvenient to install too high.

Contents of the invention

In order to solve the above-mentioned technical problems, the utility model adopts a technical solution as follows: a drainage device for a defecation device, which is characterized in that it includes an air intake branch pipe and an exhaust pipe whose lower half is arranged in the sewer, and the upper end is connected to each other. The connection between the air branch pipe and the exhaust pipe is higher than the highest position that the water surface at the upper end of the water flow may reach during the entire drainage process of the defecator; the lower end of the air intake branch pipe is the air inlet, which opens downward and is located in the toilet trap and the sewer Between the water traps, and higher than the water level; the exhaust duct is made of elastic material, and its end opening reaches the upper part of the downstream horizontal section of the sewer or reaches the vertical pipe of the sewer.

Further, an air intake hole for auxiliary air intake is formed on the side wall of the lower half of the air intake branch pipe next to the air intake port, so as to enhance the air intake volume at the beginning of drainage.

Further, the exhaust duct is made of a hose with a steel wire skeleton.

Further, a detachable cap is provided at the communication place between the intake branch pipe and the exhaust duct.

Further, the end of the exhaust conduit can be fixed on the top of the downstream horizontal section of the sewer or in the vertical sewer pipe near the horizontal section through a pipe clamp, and hang down to prevent the water from flowing backward into the exhaust conduit when the sewage is discharged.

The technical effect of the utility model is: the accelerated drainage device of the utility model can eliminate the air cushion obstruction between the upper and lower water seals as soon as possible when the toilet drains, promotes the formation of a complete siphon condition for drainage as soon as possible, accelerates the drainage process, and will not be in the two Dirt is accumulated between the drain traps, clean and hygienic, and the structure is simple and easy to install; at the same time, the accelerated drainage device is also equipped with an inspection port, which is convenient for observation and maintenance or to connect a pipe to the exhaust channel of the bathroom to enhance or replace the original exhaust efficiency .

It is especially worth mentioning that this structure only requires the user to complete the installation in his own room. Even if the sewer trap is located in the neighbor's house on the lower floor, there is no need to disturb the neighbor's assistance. This structure is also especially suitable for a common convenience in residential buildings. If there is a sewer vertical pipe near the bottom of the pool, the toilet manufacturer can provide the branch pipes and conduits in this structure as accessories to the user as optional items, so as to facilitate the installation and use.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, it includes an intake branch pipe 1 and an exhaust conduit 2 whose lower half is arranged in the sewer 6 and whose upper ends communicate with each other. The upper end of the water surface may reach the highest position. The lower end of the air intake branch pipe 1 is the air intake port 3. In order to further increase the air intake effect, there is an auxiliary air intake pipe at the side wall of the lower half of the air intake branch pipe 1 close to the air intake port 3. air intake hole 7, to strengthen the air intake at the beginning of drainage; the air intake 3 opens downward and is located between the toilet trap 4 and the sewer trap 5, and is slightly higher than the sewer trap 5 storage surface; the exhaust conduit 2 is made of elastic material, and its end opening reaches the upper part of the horizontal section downstream of the sewer 6. In order to facilitate fixing, the end of the exhaust conduit 2 is fixed on the top of the horizontal section downstream of the sewer 6 by a pipe clamp 9. Lengthen exhaust conduit 2, make it reach in the sewer vertical pipe, hang down naturally and get final product.

Further, the exhaust conduit 2 is made of a flexible pipe with a steel wire frame, so that the end thereof can be installed through a sewer trap. If it is close to the vertical pipe of the sewer, it can directly reach the vertical pipe, and the air outlet is placed downward; if it is far away from the vertical pipe of the sewer, it should be far enough away and fixed on the upper end of the inner wall of the pipe. In order to prevent the sewage from being poured into the exhaust duct at the end of the drainage and affect the exhaust performance. If water enters the exhaust pipe in case, it can also be automatically removed after a drainage cycle.

Further, a detachable cap 8 is provided at the connection between the intake branch pipe 1 and the exhaust conduit 2, and the cap 8 is opened as a conduit inspection port; the connection can pass from the toilet body to the outside, and can also be connected from the toilet to the ground. It is fixed at an appropriate place above the ground, and is provided with a cap 8 connected by threads. The cap 8 is screwed during normal use. When the urinal sewage is blocked, the cap 8 can be unscrewed to dredge the intake branch pipe 1 and the urinal. Exhaust duct 2, observe the changes of the situation, and assist in maintenance; if the end of the exhaust duct 2 is blocked or has other problems, it can also be used as a temporary replacement for the exhaust port, or it can be led to the toilet to exhaust through the duct, so as to maintain the accelerated drainage of the toilet The device works normally.

Working process: After the sewage discharge starts, with the large water flow into the toilet, the water surface in the toilet rises rapidly, and the sewage flow crosses the toilet trap 4 to form a siphon discharge, and the sewage potential is relatively large; when the sewage flow reaches the upper and lower two In the section of the drain pipe between the water traps, the gas in this section enters the intake branch pipe 1 from the air inlet 3 and the air intake hole 7, and then enters the exhaust pipe upward from the connection between the intake branch pipe 1 and the exhaust pipe 2 2. Then go downward through the sewer trap 5 in the exhaust conduit 2, and finally discharge from the end of the exhaust conduit 2 into the downstream of the sewer trap 5, without forming an air cushion to hinder the sewage flow, and the water flow will quickly enter the sewer trap 5. Inertia pushes the water stored in the sewer trap 5 to flow downstream of the sewer pipe, forming a complete siphon in the entire section of the sewage flow, and the sewage is discharged smoothly;
