Description

Technical Field

[0001] The invention relates to the technical field of sanitary ware, in particular to a toilet. Background Art

[0002] Toilets, also known as toilets, are divided into drop-type and siphon-type according to the sewage discharge method. The drop-type uses the gravity of flushing water to discharge waste, and only positive pressure is formed during the flushing and sewage discharge process, without negative pressure. The siphon-type uses a certain pressure (siphon phenomenon) formed after the flushing water fills the sewage pipe to discharge waste, and is a push-type structure.

[0003] To achieve the same flushing effect, the water consumption of a drop-type toilet is 8L, while the water consumption of a siphon toilet can be reduced to 5L. However, reducing the amount of water used in a single flush of a toilet has always been a technical problem that needs to be continuously improved and a technical effect that needs to be pursued in this technical field. Therefore, it is urgent to propose a new toilet flushing method to achieve a more water-saving and energy-saving effect.

[0004] In addition, most toilets are currently installed and fixed on the ground, and the height cannot be adjusted, and the height of use cannot be adjusted according to the height of the user.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In response to the problems pointed out in the background technology, the present invention proposes a toilet with a dual-power siphon structure, which can significantly reduce the water consumption while achieving the same sewage discharge effect. At the same time, the toilet can also be raised and lowered to meet the needs of users of different heights.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: The present invention provides a toilet, comprising: A main body, in which a toilet cavity and a mounting cavity are formed, wherein the toilet cavity has a flushing inlet and a flushing outlet; A flushing pipeline is arranged in the installation cavity and communicated with the flushing inlet for flushing water into the toilet cavity; A sewage pipe is arranged in the installation cavity and communicated with the flushing outlet. A first water seal area is formed at the communication position between the sewage pipe and the flushing outlet, a second water seal area is formed in the sewage pipe, and the sewage outlet of the sewage pipe extends to the rear of the main body; A water tank is disposed in the installation cavity, the water tank is in communication with the flushing pipeline, and is used to supply water to the flushing pipeline; a vent pipe connected between the water tank and the sewage pipe, wherein the connection position between the vent pipe and the water tank is higher than the upper limit of the water storage level of the water tank, and the connection position between the vent pipe and the sewage pipe is located on the pipe between the first water seal area and the second water seal area; The lifting assembly is arranged at the rear of the main body and is used for adjusting the distance between the main body and the ground.

[0008] Compared with the prior art, the advantages and positive effects of the present invention are: The toilet disclosed in the present application is a dual-power siphon type sewage discharge method. The setting of the ventilation pipeline makes the siphon in the sewage pipe a dual-power structure of "pushing forward and pulling back" for the water and sewage in the toilet bowl cavity, thereby greatly reducing the water consumption while achieving the same sewage discharge effect.

[0009] When the water level in the water tank reaches the upper water storage limit, since the connection position between the ventilation pipeline and the water tank is higher than the upper water storage limit of the water tank, the water in the water tank can be effectively prevented from flowing into the sewage pipe through the ventilation pipeline.

[0010] The sewage outlet of the sewage pipe extends to the rear of the main body, which is a wall-mounted toilet to meet the drainage needs of the same floor of some buildings.

[0011] The lifting component is adjusted according to the user's height, and the distance between the main body and the ground is adjusted to place the main body at an appropriate height to improve the user experience. The setting position of the lifting component fully utilizes the gap between the wall-mounted toilet and the rear wall, and the layout is compact.

[0021] This embodiment discloses a toilet, referring to Figures 1 to 6 The utility model comprises a main body 100, a sewage pipe 200, a flushing pipe 400, a ventilation pipe 500, a water tank 300, a lifting assembly 900 and the like.

[0022] The main body 100 is a ceramic structure, in which a toilet chamber 110 and an installation chamber 120 are formed. The installation chamber 120 is used to install a sewage pipe 200, a flushing pipe 400, a ventilation pipe 500, a water tank 300, etc. The overall structure of the toilet is compact, small in size, and occupies little space. Figure 6 2 is a schematic longitudinal cross-sectional view of the main body 100 .

[0023] The toilet chamber 110 has a flushing water inlet and a flushing water outlet 114. Flushing water for sewage discharge flows into the toilet chamber 110 from the flushing water inlet to flush the waste in the toilet chamber 110, and the waste in the toilet chamber 110 is discharged from the flushing water outlet 114 under the action of the water flow.

[0024] The flushing pipe 400 is disposed in the installation cavity 120, and the flushing pipe 400 is connected to the flushing inlet for flushing water into the toilet cavity 110. The flushing inlet can be disposed at multiple locations so that the flushing pipe 400 can flush water to multiple locations of the toilet cavity 110 at the same time, thereby improving the sewage discharge effect.

[0025] The sewage pipe 200 is disposed in the installation cavity 120 , and the sewage pipe 200 is connected to the flushing outlet 114 for discharging waste in the toilet cavity 110 .

[0026] A first water seal area 210 is formed at the connection position between the sewage pipe 200 and the flushing outlet 114, and a second water seal area 220 is formed in the sewage pipe 200. The first water seal area 210 and the second water seal area 220 are formed at the Figure 5 The sewage pipe 200 forms a double water seal structure through its own bending structure, which effectively prevents the odor from overflowing.

[0027] The water tank 300 is disposed in the installation cavity 120 , and the water tank 300 is communicated with the flushing pipe 400 for supplying water to the flushing pipe 400 .

[0028] The ventilation pipe 500 is connected between the water tank 300 and the sewage pipe 200. The connection position between the ventilation pipe 500 and the water tank 300 is higher than the upper water storage limit 360 of the water tank 300. The connection position between the ventilation pipe 500 and the sewage pipe 200 is located on the pipe between the first water seal area 210 and the second water seal area 220.

[0029] During sewage discharge, the water tank 300 supplies water to the flushing pipe 400, and the water in the water tank 300 flows into the toilet chamber 110 through the flushing pipe 400 and the flushing inlet to flush the dirt in the toilet chamber 110. During this process, the water level in the water tank 300 continues to drop, and a negative pressure is formed in the upper space of the water tank 300. Under the action of the negative pressure, the air in the pipe between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipe 500, so that a negative pressure is also formed in the pipe between the first water seal area 210 and the second water seal area 220, thereby forming a pulling force in front of the first water seal area 210 (along the water flow direction), sucking the water in the toilet chamber 110 and increasing the water flow rate. In this way, there are two driving forces for the water and waste in the toilet bowl cavity 110 to be discharged outward along the sewage pipe 200. One driving force is the flushing power of water flowing into the toilet bowl cavity 110 from the flushing pipe 400 and the flushing inlet, and the other driving force is the water absorption power of the water in the toilet bowl cavity 110 formed by the air in the pipe between the first water seal area 210 and the second water seal area 220 flowing into the water tank 300 through the ventilation pipe 500, thereby absorbing the water in the toilet bowl cavity 110, thereby making the flushing and sewage discharge speed faster and achieving a better sewage discharge effect with the least amount of water.

[0030] This toilet adopts a dual-power siphon type sewage discharge method. The setting of the ventilation pipe 500 makes the siphon in the sewage pipe 200 become a dual-power structure of "pushing forward and pulling back" for the water and sewage in the toilet chamber 110, thereby greatly reducing the water consumption while achieving the same sewage discharge effect.

[0031] When the water level in the water tank 300 reaches the water storage upper limit 360, since the connection position between the ventilation pipe 500 and the water tank 300 is higher than the water storage upper limit 360 of the water tank 300, the water in the water tank 300 can be effectively prevented from flowing into the sewage pipe 200 through the ventilation pipe 500.

[0032] There is a certain distance between the water storage upper limit 360 of the water tank 300 and the top of the water tank 300 , which is equivalent to reserving an air filling space at the top of the water tank 300 , and one end of the ventilation pipeline 500 is connected to the air filling space.

[0033] The lifting assembly 900 is disposed at the rear of the main body and is used to adjust the distance between the main body 100 and the ground 20. The toilet is disposed against the wall 30, and the lifting assembly 900 is disposed in the gap between the main body 110 and the back wall 30. Figure 1 and Figure 2 .

[0034] The lifting assembly 900 is adjusted according to the height of the user, and the distance between the main body 100 and the ground 20 is adjusted so that the main body 100 is placed at a suitable height position to improve the user experience.

[0035] In some embodiments of the present application, refer to Figure 5 The communication position between the ventilation pipeline 500 and the sewage pipe 200 is located at the top of the sewage pipe 200. When the sewage is discharged along the sewage pipe 200, it can effectively prevent the sewage from flowing back into the water tank 300 along the ventilation pipeline 500.

[0036] In some embodiments of the present application, refer to Figure 5 The sewage outlet of the sewage pipe 200 extends to the rear of the main body 100, that is, the toilet is a wall-mounted type.

[0037] A sewage connecting pipe 240 is arranged in the wall 30 behind the toilet, which is used to connect the sewage pipe 200 with the outdoor sewage main pipe.

[0038] The location of the lifting assembly 900 fully utilizes the gap between the wall-mounted toilet and the rear wall, and the layout is compact.

[0039] In some embodiments of the present application, refer to Figure 5The sewage pipe 200 includes a sewage pipe section 1 231, a sewage pipe section 232, a sewage pipe section 3 233, and a sewage pipe section 4 234 which are connected in sequence. The sewage pipe section 1 231 extends obliquely upward from the flush outlet 114, the sewage pipe section 232 extends downward from the top of the sewage pipe section 1 231, the sewage pipe section 3 233 extends obliquely upward from the bottom of the sewage pipe section 232 in a direction away from the sewage pipe section 1 231, and the sewage pipe section 4 234 extends horizontally from the top of the sewage pipe section 3 233 to the rear of the toilet.

[0040] A first water seal area 210 is formed at a connection position between the first sewage pipe section 231 and the flushing outlet 114 , and a second water seal area 220 is formed at a connection position between the second sewage pipe section 232 and the third sewage pipe section 233 .

[0041] One end of the ventilation pipe 500 is arranged at the connecting position between the sewage pipe section 1 231 and the sewage pipe section 232, so that the ventilation pipe 500 is located at the top of the sewage pipe 200 to prevent sewage from flowing back into the ventilation pipe 500 during sewage discharge.

[0042] In some embodiments of the present application, refer to Figure 7 or Fig.10 The flushing pipeline 400 includes a flushing main pipeline 410, a first flushing branch pipeline 420, and a second flushing branch pipeline 430. The flushing main pipeline 410 is provided with a water pump 450. The flushing main pipeline 410, the first flushing branch pipeline 420, and the second flushing branch pipeline 430 are connected through a water diversion valve 440. The flushing main pipeline 410 is connected to the water tank 300.

[0043] Reference Figure 5 and Figure 6 A sewage inlet chamber 113 and a first flushing water inlet 111 communicating with the sewage inlet chamber 113 are provided at the bottom of the toilet chamber 110 . A flushing water outlet 114 is communicated with the sewage inlet chamber 113 . The first flushing water inlet 111 and the flushing water outlet 114 are arranged opposite to each other.

[0044] A water guide groove 115 is provided at the top of the toilet chamber 110 along its circumferential direction, and a second flushing water inlet 112 communicating with the water guide groove 115 is provided at the top of the toilet chamber 110 .

[0045] The first flushing water branch pipe 420 is in communication with the first flushing water inlet 111 , and the second flushing water branch pipe 430 is in communication with the second flushing water inlet 112 .

[0046] When flushing the toilet, the water in the water tank 300 flows into the first flush branch pipe 420 and the second flush branch pipe 430 through the flush main pipe 410 and the water diverter valve 440. The water in the second flush branch pipe 430 flows out from the second flush inlet 112. During the flow along the water guide groove 115, the water flows along the inner circumferential wall of the toilet chamber 110 to the sewage inlet chamber 113 to flush the dirt in the toilet chamber 110. The water in the first flush branch pipe 420 is flushed into the sewage inlet chamber 113 from the first flush inlet 111, pushing the dirt in the sewage inlet chamber 113 to the flush outlet 114, and flows into the sewage pipe 200 to discharge the dirt.

[0047] In some embodiments of the present application, the amount of water entering the first flush branch pipe 420 from the main flush pipe 410 is less than the amount of water entering the second flush branch pipe 430, so that more water flows downward from the top of the toilet chamber 110, thereby improving the sewage flushing effect of the toilet chamber 110 and helping to reduce water consumption.

[0048] There are two driving forces for the flow of sewage in the sewage inlet chamber 113 into the sewage discharge pipe 200. One driving force is the flushing power flowing out from the first flushing inlet 111, which flushes the sewage in the sewage inlet chamber 113 into the sewage discharge pipe 200. The other driving force is that the air in the pipe between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipe 500, and a negative pressure is formed in the pipe between the first water seal area 210 and the second water seal area 220 to absorb water and sewage in the sewage inlet chamber 113. The water absorption power makes the flushing and sewage discharge speed faster and achieves a better sewage discharge effect with the least amount of water.

[0049] It is precisely because the siphon in the sewage pipe 200 can achieve a dual-power effect of "pushing forward and pulling backward" on the water and waste in the toilet chamber 110, so the amount of water distributed into the first flushing branch pipe 420 through the water diverter valve 440 does not need to be large, so that more water can flow into the second flushing branch pipe 430, and more water flows downward from the top of the toilet chamber 110, thereby improving the sewage flushing effect of the toilet chamber 110 and achieving the effect of reducing water consumption.

[0050] Regarding the location of the water tank 300 relative to the sewage pipe 200, this embodiment provides two implementations. The first implementation is that the water tank 300 is side-mounted, that is, the water tank 300 is located beside the sewage pipe 200. Figures 3 to 8 The second type is a top-mounted water tank 300, that is, the water tank 300 is disposed above the sewage pipe 200, such as Figures 9 to 14 shown.

[0051] In some embodiments of the present application, refer to Figures 3 to 6The water tank 300 is arranged beside the sewage pipe 200. The installation cavity 120 includes a first installation cavity 121 and a second installation cavity 122 which are connected. The first installation cavity 121 is located behind the toilet cavity 110, and the second installation cavity 122 surrounds the toilet cavity 110. Specifically, the first installation cavity 121 is a large space located behind the toilet cavity 110, and the second installation cavity 122 is a small space surrounding the outer periphery of the toilet cavity 110.

[0052] The sewage pipe 200 is arranged in the first installation cavity 121, occupying most of the space of the installation cavity 120. How to reasonably arrange components such as the water tank 300, the flushing pipe 400, and the ventilation pipe 500 in a limited space is an area where the toilet needs to be improved.

[0053] In this embodiment, the water tank 300 is arranged close to one side of the installation cavity 120, a part of the water tank 300 is located in the first installation cavity 121, and the other part of the water tank 300 extends into the second installation cavity 122. The water tank 300 as a whole is a vertically flat structure, that is, the width of the water tank 300 is relatively narrow to fully utilize the narrow space between the sewage pipe 200 and the side wall of the main body 100. By lengthening the length of the water tank 300 and extending the front part of the water tank 300 into the second installation cavity 122, not only can the narrow space on the outer peripheral side of the toilet cavity 110 be fully utilized, but also the volume of the water tank 300 can be guaranteed, and the sewage flushing water volume can be guaranteed.

[0054] The flushing pipe 400 is disposed at the front side of the water tank 300 and is located in the second installation cavity 122 , making full use of the narrow space around the toilet bowl cavity 110 .

[0055] In this embodiment, a water pump 450 is provided on the flushing main line 410 to provide power for the water flow.

[0056] In some embodiments of the present application, refer to Figure 8 The water tank 300 is provided with a first pipe joint 311 and a second pipe joint 312 on the side wall facing the sewage pipe 200 , and a third pipe joint 313 is provided on the front end side wall of the water tank 300 .

[0057] The first pipe joint 311 is connected to the ventilation pipeline 500, the second pipe joint 312 is connected to the water inlet pipeline, and the third pipe joint 313 is connected to the flushing pipeline 400. A water inlet solenoid valve 340 is provided at the water inlet pipeline to control the on and off of the water inlet.

[0058] Since the water tank 300 is arranged close to one side of the installation cavity 120, that is, the water tank 300 is arranged close to one side wall of the main body 100, the gap between the water tank 300 and the side wall of the main body 100 is small, and it is not easy to run pipes. Therefore, the first pipe joint 311 and the second pipe joint 312 are arranged on the side of the water tank 300 facing the sewage pipe 200 to facilitate pipe running.

[0059] The third pipe joint 313 is arranged on the front end side wall of the water tank 300, so that the flushing pipe 400 is located beside the toilet cavity 110 and in front of the water tank 300. The flushing pipe 400 is equivalent to being located in the second installation cavity 122, making full use of the narrow space around the toilet cavity 110, further improving the compactness of the structure. At the same time, the front end of the water tank 300 is also closer to the toilet cavity 110, which also helps to reduce the length of the flushing pipe 400.

[0060] In some embodiments of the present application, refer to Figure 8 The water tank 300 is provided with a mounting groove 335 on the side wall facing the sewage pipe 200. The mounting groove 335 is arranged near the bottom of the water tank 300. The second pipe joint 312 is arranged at the mounting groove 335. The second pipe joint 312 is provided with a water inlet solenoid valve 340, and the water inlet solenoid valve 340 is connected to the water inlet pipeline. The water inlet solenoid valve 340 has a certain volume. The setting of the mounting groove 335 provides an installation space for the water inlet solenoid valve 340 to avoid interference between the water inlet solenoid valve 340 and the sewage pipe 200 on the side.

[0061] In some embodiments of the present application, refer to Figure 8 The outer contour of the water tank 300 is divided into a first portion 351 and a second portion 352 along its length direction. The height of the first portion 351 is greater than the height of the second portion 352. The first portion 351 is located in the first installation cavity 121, and the second portion 352 extends into the second installation cavity 122.

[0062] That is to say, the outer contour of the water tank 300 is shorter in the front and higher in the back along its length direction, and the second portion 352 which is shorter in the front is convenient for extending into the second installation cavity 122 with a narrow peripheral space of the toilet cavity 110 .

[0063] In other embodiments of the present application, refer to Figures 9 to 13 The water tank 300 is arranged above the sewage pipe 200 and the flushing pipe 400. The water tank 300 and the sewage pipe 200 are arranged up and down. The water in the water tank 300 flows into the flushing pipe 400 under the action of gravity. The water pump is eliminated, which helps to reduce product costs and flushing reliability.

[0064] Since the water pump is eliminated, a control valve is provided in the flushing pipeline 400 to control the on-off of the flushing pipeline 400. When flushing, the control valve is opened, and the water in the water tank 300 flows into the toilet chamber 110 through the flushing pipeline 400 under the action of gravity. When not flushing, the control valve is closed.

[0065] In this specific embodiment, the control valve is a water diverter valve, that is, the water diverter valve has an opening and closing function. When the water diverter valve 440 is closed, the connection between the main flushing line 410 and the first flushing branch line 420 and the second flushing branch line 430 is cut off. When the water diverter valve 440 is opened, the main flushing line 410, the first flushing branch line 420, and the second flushing branch line 430 are connected.

[0066] The flushing main line 410 is connected to the bottom of the water tank 300 to fully utilize gravity to achieve flushing.

[0067] In some embodiments of the present application, refer to Fig.10 A clearance groove 333 is provided at the bottom of the water tank 300 , the top of the sewage pipe 200 is directly opposite to the clearance groove 333 , and the ventilation pipeline 500 passes through the clearance groove 333 .

[0068] Since the water tank 300 is located above the sewage pipe 200, the setting of the clearance groove 333 fully utilizes the gap between the water tank 300 and the sewage pipe 200. The clearance groove 333 provides space for the ventilation pipe 500, improves the compactness of the layout of the water tank 300, the sewage pipe and the ventilation pipe 500 in the upper and lower directions, and also plays a certain limiting role on the ventilation pipe 500.

[0069] In some embodiments of the present application, refer to Fig.10 The flushing pipeline 400 is located beside the sewage pipe 200 and below the water tank 300. A control unit 10 is provided at the bottom of the water tank 300. The control unit 10 is located at another opposite side of the sewage pipe 200. The control unit 10 is used to control the opening and closing of the flushing related control valves.

[0070] The flushing pipe 400 is arranged beside the sewage pipe 200, and the gap between the sewage pipe 200 and the inner wall of the main body 100 is fully utilized to improve the compactness of the structure. The control unit 10 is arranged on the other side, and the gap between the sewage pipe 200 and the other opposite inner wall of the main body 100 is fully utilized. In addition, the flushing pipe 400 and the control unit 10 are relatively separated, so as to avoid damage to the control unit 10 when the flushing pipe 400 has a fault such as leakage.

[0071] In some embodiments of the present application, the toilet further includes a cleaning heating component 800, referring to Fig. 9 and Fig.13 The cleaning and heating component 800 includes a cleaning solenoid valve 810, a cleaning heater 820, and a cleaning water outlet 830 connected in sequence. The cleaning water pump 850 provides power for the water flow in the cleaning and heating component 800.

[0072] When the cleaning button is pressed, water starts to flow into the cleaning solenoid valve 810. The water source of the cleaning solenoid valve 810 is independent and filtered in advance. The water enters the cleaning heater 820 for heating. According to the temperature control instruction of the control unit 10, the water is heated to a suitable temperature and then enters the cleaning water outlet 830 and flows out.

[0073] The cleaning solenoid valve 810 and the cleaning heater 820 are arranged at the bottom of the water tank 300 , and are arranged on different sides from the control unit 10 , so as to fully utilize the installation space at the bottom of the water tank 300 .

[0074] The water tank 300 in this embodiment not only serves as a water storage device, but also serves as an installation carrier for the control unit 10 and the cleaning and heating component 800.

[0075] The water tank 300 is provided with a pipe outlet 332 which passes through from top to bottom. A mounting seat 334 is provided on the upper part of the water tank 300. The cleaning water outlet 830 is arranged on the mounting seat 334. The water pipe 840 between the cleaning water outlet 830 and the cleaning heater 820 passes through the pipe outlet 332 to facilitate pipe routing.

[0076] In some embodiments of the present application, refer to Fig.13 and Fig.14 The water tank 300 includes an upper shell 321 and a lower shell 322, and the upper shell 321 and the lower shell 322 are connected up and down to form a water storage chamber.

[0077] An air pipe 331 is provided in the lower shell 322. The air pipe 331 and the lower shell 322 are integrally formed. There is a gap between the upper end of the air pipe 331 and the upper shell 321. The water storage upper limit of the water storage chamber is lower than the upper end of the air pipe 331. The lower end of the air pipe 331 is connected to the ventilation pipeline 500.

[0078] Since the ventilation pipe 500 is connected to the bottom of the water tank 300, the setting of the air pipe 331 is equivalent to extending the air inlet port of the ventilation pipe 500 upward, so that the ventilation pipe 500 is connected to the upper space in the water tank 300, preventing the water in the water tank 300 from flowing into the sewage pipe 200 through the ventilation pipe 500.

[0079] Connecting the ventilation pipe 500 to the bottom of the water tank 300 has another function. Since the water tank 300 is placed on top, the ventilation pipe 500, the flushing pipe 400, and the sewage pipe 200 are all located at the bottom of the water tank 300, making full use of the installation space at the bottom of the water tank 300, which helps to improve the compactness of the structure and reduce the overall height of the toilet.

[0080] A first pipe joint 311 and a second pipe joint 312 are provided at the bottom of the lower shell 322 . The first pipe joint 311 is vertically connected to the air pipe 331 . The first pipe joint 311 is used to connect to the ventilation pipeline 500 , and the second pipe joint 312 is used to connect to the flushing main pipeline 410 .

[0081] In some embodiments of the present application, a clearance groove 333 for routing the ventilation pipe 500 is provided on the lower shell 322 , a pipe routing port 332 is provided on the upper shell 321 , the pipe routing port 332 is connected to the clearance groove 333 , and a mounting seat 334 is provided on the upper portion of the upper shell 321 .

[0082] The arrangement of the giving groove 333 and the pipe outlet 332 in the front middle area of ​​the water tank 300 enables the water tank 300 to integrate the pipe routing function, making the pipe routing of the pipeline more regular, compact and reliable.

[0083] In some embodiments of the present application, a liquid level sensor 600 is provided in the water tank 300 for detecting the amount of water in the water tank 300.

[0084] When the toilet receives a flush signal, the water tank 300 supplies water to the flush pipe 400. One water path is sprayed into the sewage inlet chamber 113 through the first flush branch pipe 420 and the first flush inlet 111 to spray and flush the water and sewage in the sewage inlet chamber 113. The other water path flows into the circumferential water guide groove 115 on the top of the toilet chamber 110 through the second flush branch pipe 430 and the second flush inlet 112, flows along the inner wall of the toilet chamber 110 to the sewage inlet chamber 113 to flush the sewage in the toilet chamber 110. At the same time, the water level in the water tank 300 continues to drop, and the water tank 300 is turned off. A negative pressure is formed in the upper space in the water tank 300. Under the action of the negative pressure, the air in the pipe between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipe 500, so that a negative pressure is also formed in the pipe between the first water seal area 210 and the second water seal area 220, thereby forming a pulling force in front of the first water seal area 210 (along the water flow direction), sucking the water and dirt in the sewage inlet chamber 113. The water and dirt in the sewage inlet chamber 113 are discharged from the sewage pipe 200 under the dual action of the flushing power and the negative pressure suction power; When the liquid level sensor 600 detects that the water level in the water tank 300 drops to the first position, the water tank 300 stops supplying water to the flushing pipe 400, and the water inlet pipe starts to replenish water into the water tank 300 until the liquid level sensor 600 detects that the water level in the water tank 300 rises to the water storage upper limit 360 and stops replenishing water.

[0085] When the water tank 300 is replenished with water, the water level in the water tank 300 continues to rise, and the air at the top of the water tank 300 flows into the pipeline between the first water seal area 210 and the second water seal area 220 through the ventilation pipeline 500.
