The first jet orifice 4 is higher than the lowest point 212 of the dirt inlet, and specifically, the first jet orifice 4 is located on the left side pipe wall or the right side pipe wall or the upper side pipe wall of the siphon pipe 2.
In the present embodiment, the first injection port 4 is located in front of the lowest point 212 of the dirt inlet, and the first injection port 4 is located behind the highest point 211 of the dirt inlet. Thus, the first injection port 4 is easier to process, and the processing efficiency is improved. This is because the space of the toilet at the soil inlet 21 of the siphon pipe 2 is large and the worker has enough working space to process the first jet port 4.
In this embodiment, the number of the first injection ports 4 is two, the two first injection ports 4 are respectively located on the pipe walls on the left and right sides of the siphon pipe 2, and the two first injection ports 4 are located in left and right correspondence. In other embodiments, the number of the first injection ports is one, and the first injection ports are located on the pipe wall of the left side or the right side of the siphon pipe, or the first injection ports are located on the upper pipe wall of the siphon pipe.
In the present embodiment, a second jet port 5 is provided at the bottom of the front end of the toilet bowl 1, the second jet port 5 faces the dirt inlet 21 of the siphon pipe 2, and the second jet port 5 is higher than the lowest point 212 of the dirt inlet.

The water supply source for the spray channel 6 is from a water tank 7 located above it. In other embodiments, the toilet of the present invention has no water tank, and the first/second jet ports are directly supplied with tap water.
In this embodiment, as shown in fig. 4, the second injection ports 5 are higher than the first injection ports 4, and the height difference between the first injection ports 4 and the second injection ports 5 is less than 20mm, preferably 15 mm; the aperture of the first injection ports 4 is larger than that of the second injection ports 5, the sum of the apertures of the two first injection ports 4 and the aperture of the second injection ports 5 is 40-44 mm, specifically, the aperture of the first injection ports 4 is 15mm, and the aperture of the second injection ports 5 is 14mm, but the invention is not limited to this; the horizontal distance between the highest point 211 and the lowest point of the sewage inlet in the front-rear direction is 40-60 mm, and a preferred value is 55 mm; the horizontal distance between the lowest point 212 of the sewage inlet and the bottom of the front end of the urinal 1 is 120-180 mm, and a preferred value is 155 mm; the height difference between the high end and the low end of the slope surface 3 is less than 70mm, and the preferred value is 60 mm.
In this embodiment, a brush ring hole (not shown) is formed in the top of the urinal 1. The invention also comprises a brush ring water channel (not shown in the figure), and the brush ring hole is communicated with the brush ring water channel. The number of the brush ring holes may be a small number, such as one or two, or many, and the brush ring holes are arranged at intervals along the circumferential direction of the urinal 1. When the number of the brush ring holes is a small number, the water outlet direction of the brush ring holes is arranged along the circumferential direction of the urinal 1, and the top of the urinal 1 can be provided with a water guide table or a water guide groove so as to guide water flow to flow along the circumferential direction of the urinal 1.
According to the siphon closestool, the dirt discharged into the urinal 1 reaches the lowest point 212 of the dirt inlet along the slope 3, the highest point 211 of the dirt inlet and the lowest point 212 of the dirt inlet are vertically staggered, and the horizontal distance between the highest point 211 of the dirt inlet and the lowest point 212 of the dirt inlet is 40-60 mm, so that the dirt is not easy to touch the highest point 211 of the dirt inlet, and the dirt can be prevented from blocking the dirt inlet 21. When the flushing is started, because the distance between the first jet orifice 4 and the jet water channel 6 is short, the water in the jet water channel 6 reaches the first jet orifice 4 firstly, the jet force of the first jet orifice 4 is large, the first jet orifice 4 is positioned on the pipe wall of the sewage inlet 21, and the front part of the first jet orifice is not blocked by the sewage, so that the siphon pipeline 2 can be quickly filled with the water flow jetted from the first jet orifice 4, and the siphon is formed at high speed; the water flow ejected from the second ejection port 5 is ejected to the dirt inlet 21 of the siphon pipe 2 to assist siphon formation. Therefore, the invention greatly improves the sewage discharge capability and can save the flushing water. The water flow flowing out from the brush ring hole flushes the inner wall surface of the urinal 1, and the complete flushing function is realized. The direction of water flow during the flushing process of the present invention is shown in fig. 5.
The quantity of first jet 4 is two, not only makes the flow bigger, can fill out siphon pipeline 2 more fast to accelerate to produce the siphon, still make two first jet 4 spun rivers between two parties, can not tend to the party of no first jet, thereby make the filth can impel in siphon pipeline 2 in the centre, and when the filth reachd the position of first jet 4, two first jet 4 can carry out the helping hand simultaneously, make the filth change the discharge. In addition, because the siphon finishes when air enters the siphon pipeline 2 at the water seal sealing point (namely the highest point 211 of the sewage inlet), and the two first injection ports 4 are arranged, the time for the air to enter can be delayed, and the siphon time is longer.
Compared with the mode that the first jet orifice is arranged on the upper side wall of the siphon pipeline, the first jet orifice 4 is arranged on the left side wall or the right side wall of the siphon pipeline 2, so that the effect of centering water flow is achieved, when dirt passes through the first jet orifice, the dirt can be prevented from being below the water flow, and the first jet orifice is prevented from being arranged above the siphon pipeline, so that the dirt is prevented from being pressed downwards by the water flow to cause poor dirt discharge effect.
When cleaning, the cleaning tool can reach the lowest point 212 of the dirt inlet along the sloping surface 3, so that the lowest point 212 of the dirt inlet can be cleaned completely.
The parts of the siphon closestool, which are not related, are the same as the prior art or can be realized by the prior art.
The above embodiments are only for further illustrating a siphon toilet of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
