[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] First embodiment:

[0029] A type of siphon toilet, such as Figure 1 As shown, the toilet includes a toilet seat 1, which has a water outlet 5, a urinal 4, and a drain outlet 6. A drain pipe connects the urinal 4 and the drain outlet 6. The water outlet 5 is located near the upper end of the urinal 4 and is used to flush water into the urinal 4. The drain outlet 6 is located at the bottom of the toilet seat 1, and waste in the urinal 4 is discharged from the drain outlet 6 through the drain pipe.

[0030] The sewage pipe includes an upward-extending section 2 and a downward-extending section 3, which are connected. In this embodiment, the upward-extending section 2 and the downward-extending section 3 are integrally formed. The downward-extending section 3 includes a bend 301 that turns backward, i.e., turns away from the upward-extending section 2. The upward-extending section 2 is connected to the toilet bowl 4, and the bend 301 is connected to the sewage outlet 6. Compared to water flowing directly from the downward-extending section 3 into the sewage outlet 6, the bend 301 slows down the water flow rate out of the pipe, increases the time the water stays in the pipe, and makes it easier for the pipe to reach full capacity, resulting in stronger siphon force and better sewage discharge.

[0031] In this embodiment, the downlink segment 3 further includes a vertically downward-facing straight section 302, located below the bend section 301. The downlink segment 3 also includes a forward-bending extension 303, located below the straight section 302, and connected to both the straight section 302 and the drain outlet 6. This design allows the downlink segment 3 to bend backwards and then bend downwards again to a vertical position at its end, making it easier to connect to the drain pipe inlet or the offset device 7, thus facilitating installation.

[0032] In other embodiments, the straight section 302 is disposed below the bend section 301, and the straight section 302 is connected to the bend section 301 and the drain outlet 6 respectively.

[0033] In other embodiments, the downlink segment 3 further includes a forward-turning extension 303, which is disposed below the turning portion 301 and is connected to the turning portion 301 and the drain outlet 6 respectively.

[0034] A sealing disc 12 (not shown) is provided at the outlet of the sewage outlet 6. The sealing disc 12 is fitted around the bottom of the sewage outlet 6 and is used to improve the sealing performance of the outlet connection.

[0035] The water outlet 5 is located on the left or right side of the rear end of the toilet bowl 4, so that the water flow from the water outlet 5 will flow down along the perimeter wall of the toilet bowl 4 and flush the waste to the bottom.

[0036] A jet hole 13 is provided at the bottom of the toilet bowl 4 on the side away from the sewage pipe. The jet hole 13 is used to spray water into the inlet of the sewage pipe to push the sewage into the upper section 2, which further enhances the sewage discharge effect.

[0037] Second embodiment:

[0038] A type of siphon toilet, such as Figure 2 and Figure 3 As shown, the difference from the first embodiment is that it also includes a shifter 7, which is movably installed at the bottom of the toilet seat 1. The shifter 7 is connected to the drain outlet 6 and the drain pipe inlet (not shown) respectively. Waste in the toilet bowl 4 flows out through the drain pipe, then through the drain outlet 6, and finally through the shifter 7 before entering the drain pipe inlet.

[0039] In this embodiment, a sealing disc 12 is provided at the outlet of the sewage outlet 6. The sealing disc 12 is sleeved on the bottom periphery of the sewage outlet 6 and is used to improve the sealing performance of the outlet connection.

[0040] The displacement device 7 includes a displacement body 701 and a connecting bend 702. The connecting bend 702 is connected to the drain outlet 6, specifically to the outlet of the straight section 302. The upper interface of the displacement body 701 is fixedly connected to the connecting bend 702 via a connecting buckle 10, or the upper interface of the displacement body 701 is movably sleeved onto the connecting bend 702. The lower interface of the displacement body 701 is connected to the drain pipe inlet. The top end of the connecting bend 702 is bent vertically upward to facilitate installation with the vertically downward straight section 302.

[0041] like Figures 4 to 6 As shown, both the displacement body 701 and the connecting bend 702 have protruding rings 9 on their surfaces, and the connecting buckle 10 has a groove on its inner side. The groove of the connecting buckle 10 wraps the protruding rings 9 of the displacement body 701 and the connecting bend 702 together, thus achieving the connection between the two.

[0042] A first sealing ring (not shown) is provided at the connection between the upper interface of the shifter body 701 and the connecting bend 702, and a second sealing ring 8 is provided at the connection between the lower interface of the shifter body 701 and the drain pipe inlet. The first sealing ring and the second sealing ring 8 are used to improve the sealing performance of the connection between the two ends of the shifter body 701. Since the lower interface extends into the drain pipe inlet, the second sealing ring 8 may not be provided at the connection between the lower interface and the drain pipe inlet in other embodiments.

[0043] The shifting body 701 extends horizontally and is provided with a plurality of cutting grooves 11. The plurality of cutting grooves 11 are arranged at equal intervals along the length of the shifting body 701. The cutting grooves 11 are used to facilitate cutting of the shifting body 701, making it easier to cut the shifting body 701 and to conveniently position the cutting position and cutting length.

[0044] In other embodiments, the upper interface of the shifting body 701 is movably sleeved on the connecting bend 702, and the lower interface of the shifting body 701 is connected to the drain pipe inlet. The required length can be maintained by extending and retracting the shifting body 701 according to the required length.

[0045] Several protruding rings 9 corresponding to the cutting grooves 11 are equidistantly arranged on the displacement body 701 along its length direction. The protruding rings 9 are in contact with the cutting grooves 11. When the displacement body 701 is cut off from a certain cutting groove 11, the connecting buckle 10 is connected to the connecting bend 702 through the protruding ring 9 at that location.

[0046] By setting the offset device 7, this solution allows for adjustment of the toilet installation distance when installing different toilet pit distances by moving the offset device 7, greatly saving bathroom installation space and improving applicability. During installation, the excess part of the offset device 701 is cut off according to the required length of the offset device 701.

[0047] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
