[0011] The utility model is further configured such that the horizontal height of the three-way seat is higher than the horizontal height of the connecting seat.

[0012] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0013] 1. The sewage discharge device provided by the utility model utilizes a three-way seat to divert the first sewage pipe connected to the toilet bowl, so that when the power is on, the suction pump component is first sucked in to perform vacuum pressurized sewage discharge. If the power is not on, the sewage enters the connecting seat through the first connecting pipe and is naturally discharged by flushing. Compared with the traditional sewage discharge device, an additional pipeline is added, which is convenient for sewage discharge and can effectively cope with the functional state of the smart toilet under extreme conditions. At the same time, the structure is simple and easy to repair and replace parts.

[0014] 2.

[0015] 3. The connection seat further provided by the utility model can effectively prevent the first connection pipe from naturally flowing down the excrement and avoid the occurrence of peculiar smell on the toilet seat.

[0016] 4. The three-way seat provided by the utility model provides a first longitudinal through hole, allowing excrement to fall into the three-way seat from the first sewage pipe with less resistance, thereby improving sewage discharge efficiency.

[0017] 5. The utility model further makes the horizontal height of the three-way seat greater than the horizontal height of the connecting seat, so that the excrement in the first connecting pipe can easily enter the connecting seat through gravity, and the sewage discharge is more efficient.

[0029] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 4 :

[0030] A sewage discharge device for a toilet comprises a first sewage discharge pipe 2 connected to the bottom of a toilet bowl 1, the lower end of the first sewage discharge pipe 2 is connected to a three-way seat 3, the two sides of the three-way seat 3 are respectively connected to a suction pump assembly 4 and a first connecting pipe 20, the other end of the first connecting pipe 20 is connected to a connecting seat 5, one side of the suction pump assembly 4 is connected to a second connecting pipe 21, and the other end of the second connecting pipe 21 is connected to a sewage inlet 50 formed at the upper end of the connecting seat 5, one side of the connecting seat 5 is connected to a second sewage discharge pipe 22, and the other end of the second sewage discharge pipe 22 is connected to a sewage discharge seat 6 extending out of the bottom of the toilet.

[0031] During the implementation process, the following two situations occurred:

[0032] One is that when the smart toilet is powered on, the suction pump assembly 4 works, and the dirt discharged from the first sewage pipe 2 is first sucked by the suction pump, and then connected to the connecting seat 5 by the second connecting pipe and finally discharged through the second sewage pipe, and the suction pump assembly adopts a vacuum pump for suction, which is highly efficient and prevents blockage;

[0033] The other is that when the power is off, the suction pump assembly stops working, and the dirt discharged from the first sewage pipe 2 enters the first connecting pipe after reaching a certain amount in the three-way seat, and then enters the second sewage pipe through the connecting seat.

[0034] In the above structure, compared with the traditional sewage discharge device, it utilizes two three-way seats with three-way effect and a connecting seat, as well as the optimization of the pipeline, to achieve the effect that the smart toilet is not easy to be blocked when it is not powered on, and the overall structure is simple and easy to inspect and maintain.

[0035] Preferably, the suction pump assembly 4 includes a pump casing 40 fixed in the toilet, the side wall of the pump casing 40 is connected to one end of the three-way seat 3, the top of the pump casing 40 is connected to the second connecting pipe 21, and a driving motor 41 is fixed to the other side of the pump casing 40. The output shaft of the driving motor 41 passes through one side of the pump casing 40, and a sewage discharge screw 42 located in the pump casing is sleeved on the protruding part.

[0036] In the above structure, the output shaft of the driving motor drives the sewage discharge screw to rotate, so that when the power is on, the three-way seat is in a negative pressure state, thereby sucking the dirt into the pump casing and then discharging it through the second connecting pipe 21, realizing efficient sewage discharge when the power is on.

[0037] Preferably, a knife strip 43 is fixed to one end of the sewage discharge screw 42 close to the three-way seat 3. The knife strip 43 cuts harder excrement or other foreign matter to prevent the vacuum pump from being blocked.

[0038] Preferably, an anti-odor cover plate 51 is hinged in the connection seat 5 , the anti-odor cover plate 51 seals the through hole in the connection seat 5 connected to the first connection pipe 20 , and a torsion spring is provided at the hinge of the anti-odor cover plate 51 .

[0039] Under normal power-on conditions, since the first connecting pipe is used for natural sewage discharge when power is not on, it often does not work, and dirt still exists in the connecting seat. In order to prevent the dirt in the connecting seat from emitting odor from the first connecting pipe, the anti-odor cover effectively performs anti-odor operations.

[0040] Preferably, a first through hole 30 arranged longitudinally is provided on the top of the three-way seat 3, and the first through hole 30 is connected to the first sewage pipe 2. Side through holes 31 connected to the first through hole 30 are provided on both sides of the three-way seat 3, and the through holes 31 on both sides are respectively connected to the suction pump assembly 4 and the first connecting pipe 20.

[0041] In a specific implementation process, the first through hole 30 is longitudinally arranged at the top of the three-way seat, which helps dirt to fall into the three-way seat.

[0042] Preferably, the horizontal height of the three-way seat 3 is higher than the horizontal height of the connecting seat 5. The height of the three-way seat is greater than that of the connecting seat, and the first connecting pipe will fall into the connecting seat by gravity, which is convenient for sewage discharge in the non-powered state.

[0043] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
