Detailed Description

The detailed description of the embodiments of the present invention will be described in conjunction with the drawings, it should be noted that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

Example (b): referring to fig. 1-4, a double-layer urinal comprises a squatting pan 1 with a concave cavity, a first flushing port 10 is arranged at the side wall of the squatting pan 1, a first sewage discharge port 13 is arranged at the bottom of the squatting pan 1, an overflow cavity 15 is arranged below the squatting pan 1, an overflow hole 19 communicated with the overflow cavity 15 is arranged at the side wall of the squatting pan 1, and a second sewage discharge port 16 is arranged at the bottom of the overflow cavity 15. First wash water notch 10 is used for linking to each other with the water pipe, water washes squatting pan 1 in following first wash water notch 10 inflow cavity after just, sewage is discharged from first drain hole 13, when first drain hole 13 blocks up, sewage can not discharge and at cavity cohesion, when the position of sewage height rising to overflow hole 19 in the cavity, sewage flows into to the overflow chamber 15 of below from overflow hole 19 in, sewage flows into and discharges from second drain 16 in the overflow chamber 15, consequently, sewage in the squatting pan 1 can not spill over and go up ground.

Further, the lateral part of the overflow cavity 15 is provided with a second flushing port 11, the second flushing port 11 is used for being connected with a water pipe, after sewage enters the overflow cavity 15, the overflow cavity 15 can be polluted, and at the moment, the second flushing port 11 is communicated and water enters, so that the inside of the overflow cavity 15 is flushed. The first flushing port 10 and the second flushing port 11 are connected with a pipeline, the pipeline can be connected with a city water supply system, and when flushing is needed, water flows out of the first flushing port 10 or the second flushing port 11. In order to make room for the connection of the first discharge opening 13, an overflow chamber 15 is provided in the front half of the lower part of the squatting pan 1, the overflow chamber 15 being separated from the first discharge opening 13.

Further, first drain 13 and second drain 16 all are connected with the U type pipe, and the U type pipe can prevent sewage backward flow, and the bath back, certain amount of water can be retained in the U type pipe, prevents that the gas in the outside from entering into indoor from first drain 13 or second drain 16. The aperture of the second sludge discharge opening 16 may be set smaller than the aperture of the first sludge discharge opening 13, considering that there is generally no bulky object in the overflow chamber 15.

The overflow holes 19 are arranged on the same height of the side wall of the squatting pan 1, when the first sewage discharge port 13 is blocked, the plurality of overflow holes 19 can better overflow sewage, and the phenomenon that the sewage overflows to the ground due to overlarge sewage amount in the squatting pan 1 is avoided. The upper layer of the squatting pan 1 is provided with the edge plates 12 around the cavity, when the cavity is flushed, water is likely to flush out of the ground along the side wall of the cavity due to the large flow rate of the water, and the edge plates 12 are arranged to block the water to prevent the water from flushing out. The interior of the edge plate 12 is hollow to form a flushing channel 18, a plurality of flushing holes 21 are arranged below the flushing channel 18, and the flushing channel 18 is connected with the first flushing port 10. The water from the first flushing port 10 flows through the flushing channel 18 and out through the flushing port, so that the cavity can be flushed in multiple directions. The total area of overflow hole 19 is not less than the total area of flushing hole 21, and when first blow-off pipe blockked up, the flushing port probably still is continuously flushing water, sets up overflow hole 19's total area into the total area that is not less than flushing hole 21, makes overflow hole 19's drainage rate can not be less than the inflow speed of flushing hole 21, avoids sewage to spill over ground.

The working principle is as follows: under normal conditions, the water is flushed after defecating, sewage is discharged from the first sewage discharge port 13, and no water exists in the overflow cavity 15. When the first sewage discharge port 13 is blocked, the height of the sewage level in the concave cavity rises, when the sewage level rises to the overflow hole 19, the sewage flows into the overflow cavity 15 from the overflow hole 19 and is then discharged from the second sewage discharge port 16, the water level in the concave cavity is kept at the height of the overflow hole, and the sewage cannot overflow.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
