Description

Technical Field

[0001] The utility model relates to a squat toilet, in particular to an ultra-thin squat toilet device with gas-liquid separation and rear discharge. Background Art

[0002] Most of the existing squat toilets are direct-discharge and return-water-bay-type drainage. The drainage pipes of these two types need to be installed under the squat toilet, and the overall height space occupied is the ceramic body + sewage pipe, which is about 35-45cm. Moreover, a return water bay must be set up under the direct-discharge squat toilet, otherwise, the room will be particularly smelly. With the popularization of prefabricated integrated public toilets, it is urgent to solve the problem of height occupancy. Most of the existing prefabricated ones have 2-3 steps, which also causes great troubles for the long-distance transportation of prefabricated facilities with an increase of 2-3 steps in height, and the indoor space can only be compressed; at the same time, the excessively high steps also have the defect of being inconvenient to get on and off the squat platform. In addition, all squat toilets have the problem of odor overflow when in use.

[0003] There is a rear-discharge siphonic squat toilet with document number CN204225346U, which includes a squat toilet body and a squat toilet bowl, a flushing channel and a sewage pipe arranged thereon. A water seal is arranged at the bottom of the squat toilet, and the water seal is connected to the sewage pipe. It is characterized in that the sewage pipe is a siphon tube, and the siphon tube includes an S-shaped siphon tube section at the front and a rear sewage discharge section at the rear extending to the rear of the squat toilet bowl, and the sewage outlet of the rear sewage discharge section is located at the rear of the squat toilet body. As a further explanation of the above scheme, the rear sewage discharge section is a combination of one or more of a horizontal sewage discharge section, an oblique sewage discharge section and a curved sewage discharge section. The S-shaped siphon tube section and the rear sewage discharge section are designed as an integral whole. The siphon tube S-shaped siphon tube section and the rear sewage discharge section are a split combined installation structure. However, its water seal will still increase the vertical installation space and there is a problem of odor overflow during use. Utility Model Content

[0004] The utility model aims to overcome the above-mentioned defects of the prior art and provide an ultra-thin squat toilet device with gas-liquid separation and rear discharge, which can not only significantly reduce the installation height, but also help prevent odor from overflowing when using the toilet.

[0005] To achieve the above-mentioned purpose, the utility model is a gas-liquid rear-discharge ultra-thin squat toilet device, which is special in that the flush squat toilet is provided with a rear discharge collection bucket, the rear discharge port is extended backward to a downwardly inclined discharge pipe with an upward exhaust and venting pipe, and the downwardly inclined discharge pipe is provided with a water-sealed odor-isolating mechanism at the downstream section of the upward exhaust and venting pipe, or the downwardly inclined discharge pipe is connected to the terminal discharge pipe with a water-sealed odor-isolating mechanism downstream. In this way, the flush squat toilet is provided with a rear discharge collection bucket for direct rear discharge, which can significantly reduce the installation height. The rear discharge port is extended backward to a downwardly inclined discharge pipe with an upward exhaust and venting pipe, which can absorb the odor generated by using the toilet in real time, prevent the odor from overflowing, and can also be facilitated by water flushing downward discharge. The water-sealed odor-isolating mechanism can also play a role in isolating the odor from the septic tank during the downward discharge process. Therefore, it has the advantages of significantly reducing the installation height, saving installation costs, preventing the odor from overflowing when using the toilet, facilitating water flushing downward discharge, playing a role in isolating the odor from the downstream during the downward discharge process, and being particularly suitable for public toilets.

[0006] As an optimization, the water seal odor isolation mechanism is a U-shaped water storage bay pipe section or pipe section. Although the U-shaped water storage bay pipe section or pipe section has a downward extension height and occupies the downward space, when it is set outdoors, it does not occupy the indoor installation height space.

[0007] As an optimization, the U-shaped water storage bay pipe section or pipe section is an intermediate U-shaped water storage bay composed of an upstream pipe section and a downstream pipe section and a front-to-back connection between the upstream pipe section and the downstream pipe section, wherein the intermediate U-shaped water storage bay can store water to isolate odor; the U-shaped water storage bay pipe section or pipe section is a downward sloping pipe section, or at least the lower part of the inner cavity of the downstream end of the upstream pipe section is higher than the lower part of the inner cavity of the upstream end of the downstream pipe section, so that it can be flushed downward smoothly and is not easy to remain in the pipeline. It is preferred that the upstream pipe section with the same inner diameter is higher than the downstream pipe section, which is conducive to preventing backflow from downstream to upstream.

[0008] As an optimization, the downward slope of the downward-sloping discharge pipe is 1-3%, which is conducive to smooth discharge without excessively occupying the vertical height; the terminal discharge pipe is downward-sloping, which is more conducive to smooth discharge, and when it is a horizontal pipe, it is convenient for installation and construction. The downward slope of the downward-sloping terminal discharge pipe is 1-3%. This is conducive to smooth discharge.

[0009] As an optimization, the upward exhaust vent pipe is located outside the toilet wall, and the flush squat toilet is located inside the toilet. In this way, it can save space in the toilet, help avoid noise in the toilet caused by forced suction and discharge, and help improve the air quality in the toilet.

[0010] As an optimization, an automatic exhaust hood is provided at the upper end of the upward exhaust vent pipe. In this way, it does not consume energy and does not rely on power supply for exhaust, which is both energy-saving and has better exhaust efficiency than direct exhaust. Or the upward exhaust vent pipe is equipped with a built-in intelligent sensor start-stop electric fan, that is, it starts and stops when someone uses the toilet, and stops when no one uses the toilet. In this way, the odor extraction efficiency can be ensured.

[0011] As an optimization, the downstream ends of the downward-sloping discharge pipe and the terminal discharge pipe are connected to a septic tank or a dedicated septic pipe network.

[0012] As an optimization, a water film-type water storage bay lower than the lower part of the inner cavity of the rear outlet is provided at the bottom of the rear outlet collecting bucket, so that the water film-type water storage bay can play a good anti-sticking role; the bottom of the rear outlet collecting bucket can also be higher than the lower part of the inner cavity of the rear outlet. In this way, when the inner surface of the rear outlet collecting bucket, especially the bottom surface, adopts an anti-sticking surface material, it can also have an anti-sticking effect in the water flushing mode, and is more conducive to clean flushing and bottom cleaning.

[0013] As an optimization, the rear outlet collecting bucket is divided into a gentle slope section, a steep slope section, and a water film type water storage bay section or a slight slope section extending the rear outlet from front to back on the opposite side of the rear outlet. The slope of the steep slope section when the slight slope section is extending the rear outlet is smaller than the slope of the steep slope section when the water film type water storage bay section is extending the rear outlet. This is more conducive to the urine flow and water flow rushing down the steep slope section with a small slope and cutting into the stool under the slight slope section, making it easier for the stool to be washed away by the flushing water flow. The slope of the steep slope section with high upstream and low downstream is greater than the slope of the gentle slope section, and the slope of the gentle slope section with high upstream and low downstream is greater than the slope of the slight slope section with high upstream and low downstream. In this way, while the slope of the gentle slope section receives the urine jet, it can also reduce the incident angle through the gentle slope, which is conducive to avoiding splashing when urine is incident. The steep slope section can increase the downward force of urine flow and flushing water flow, which is conducive to flushing the falling feces and facilitating the subsequent clean flushing, and is conducive to significantly increasing the flushing efficiency of the downward inclined discharge pipe. The water film type water storage bay section is of course conducive to anti-sticking. Compared with the flat bottom, the slight slope section is conducive to reducing the flushing resistance and facilitating clean discharge.

[0014] As an optimization, the inner diameter of the upstream end of the downward-sloping discharge pipe is larger than the outer diameter of the rear outlet, which is beneficial to avoid residues at the bottom of the collecting bucket and its rear outlet after flushing. In this way, the large diameter of the downstream pipeline is beneficial to reducing the downstream internal pressure and forming a natural exhaust airflow. The rear outlet is connected to the upstream end of the downward-sloping discharge pipe through an inner and outer sealing sleeve with a sealing ring plug. On the one hand, it is convenient for connection construction and not easy to leak. On the other hand, the front and rear diameter difference is increased by the sealing ring plug sleeve, which can further facilitate the rear outlet collecting bucket to discharge fully, smoothly and cleanly to the downward-sloping discharge pipe.

[0015] The water-sealed odor-isolating mechanism can 100% block the sewage pipe network or septic tank from connecting with the indoor environment under the premise of ensuring the liquid level. The upward exhaust vent pipe can immediately discharge the odor generated when using the toilet. The upward exhaust vent pipe can be set to a height of about 3 meters, relying on the natural convection of air to produce a chimney effect to extract the foul air in the squat toilet. The greater the temperature difference between the indoor temperature and the outdoor temperature, the better the natural extraction effect. Of course, a spherical automatic exhaust hood can be further installed on the top, and an electric fan with built-in intelligent sensing start and stop can be used, that is, it can start and stop by sensing whether someone is using the toilet. It starts when someone is using the toilet and stops when no one is using the toilet; more specifically, it controls the start and stop by sensing the human body in the toilet through the external line. Whether someone is using the toilet in operation or not in use, the squat toilet area can be guaranteed to be in a good air quality state. In particular, the squat toilet can be designed to be at least 10 centimeters high, which can save up to 71-78% of the height space, greatly saving construction costs and improving the space efficiency in the toilet, significantly reducing the step height in the squat toilet area, and making it more convenient to enter and exit the squat toilet area.

[0016] After adopting the above technical scheme, the utility model has the advantages of significantly reducing the installation height, saving installation costs, preventing odor from overflowing when using the toilet, facilitating water flushing and drainage, and being able to isolate odor from the downstream during the drainage process and being particularly suitable for public toilets.
