[0016] In some cases, toilet flushing systems that use a jet nozzle and an S-bend pipe to discharge waste have the following problems: 1. Waste is mainly discharged by using a nozzle to flush the waste into the S-bend pipe with a large water flow, which creates a lot of noise. 2. The S-bend pipe must be molded integrally with the ceramic toilet body, which requires a complicated process and is expensive. 3. The S-bend pipe has a siphon effect and can efficiently discharge waste, but it has a problem that it is not able to discharge waste cleanly when the waste is large and in large quantities.

[0017] As shown in FIGS. 1 to 12, an embodiment of the present application provides a toilet waste discharge device, which includes a plumbing assembly 1 and a switching assembly 2.

[0018] The piping assembly 1 includes a water seal pipe 12 and a waste discharge pipe 11, and the inlet end of the waste discharge pipe 11 and the inlet end of the water seal pipe 12 are both capable of communicating with a waste discharge outlet 32 ​​(described in detail below) of the toilet body 3. The waste discharge device has a waste discharge state and a water seal state, and in the waste discharge state, the waste discharge pipe 11 is configured to be used for discharging waste from the toilet body 3, and in the water seal state, the water seal pipe 12 is configured to water seal the toilet body 3.

[0019] The switching assembly 2 is configured to be able to control the waste discharge device to switch between a waste discharge state and a water seal state. When the switching assembly 2 controls the waste discharge device to the water seal state, the water seal pipe 12 communicates with the waste discharge outlet 32 ​​of the toilet body 3, thereby sealing the toilet body 3 with water and blocking odors. When the switching assembly 2 controls the waste discharge device to the waste discharge state, the waste discharge pipe 11 communicates with the waste discharge outlet 32 ​​of the toilet body 3, at which time the waste discharge pipe 11 can be used to discharge waste from the toilet body 3, and excrement in the toilet body 3 can be discharged through the waste discharge pipe 11.

[0020] The waste discharge device according to the embodiment of the present application realizes the water sealing function by the water sealing pipe 12, realizes the waste discharge function by the waste discharge pipe 11, and realizes switching between the water sealing state and the waste discharge state of the waste discharge device by the switching assembly 2, does not require a siphon waste discharge function, reduces noise when flushing the toilet, and can cleanly remove excrement from the toilet body 3. Furthermore, the piping assembly 1 of the waste discharge device can be molded separately from the toilet body 3, assembled, and connected, which reduces the difficulty of the molding process of the toilet body 3 and reduces processing costs.

[0021] In some exemplary embodiments, as shown in Figures 3-4, 9, 11-12, the waste discharge pipeline 11 has an inlet end (i.e., the first inlet end 111) and an outlet end (i.e., the first outlet end 112), and a cooperating part 13 that cooperates with the switching assembly 2 is provided within the waste discharge pipeline 11, and the switching assembly 2 is configured to control the communication (as shown in Figures 3, 9, and 11) or disconnection (as shown in Figures 4 and 12) of the waste discharge pipeline 11, i.e., the switching assembly 2 cooperates with the cooperating part 13 to connect or disconnect the waste discharge pipeline 11, thereby putting the waste discharge device into a waste discharge state or a water-sealed state.

[0022] As shown in Figures 11 and 12, the water seal pipe 12 has an inlet end (i.e., the second inlet end 121) and an outlet end (i.e., the second outlet end 122), and the inlet end (i.e., the second inlet end 121) of the water seal pipe 12 is connected to a portion of the sewage discharge pipe 11 located upstream of the cooperating portion 13, i.e., the cooperating portion 13 is located downstream of the connection portion between the sewage discharge pipe 11 and the second inlet end 121 of the water seal pipe 12, and the highest point of the water seal pipe 12 is higher than the highest point of the sewage discharge pipe 11.

[0023] When the waste discharge line 11 is disconnected, the water seal line 12 is configured to water seal the toilet, and when the waste discharge line 11 is connected, the waste discharge line 11 is configured to be used to discharge waste from the toilet.

[0024] In the waste discharge device according to the embodiment of the present application, the piping assembly 1 includes a waste discharge pipe 11 and a water seal pipe 12. A first inlet end 111 of the waste discharge pipe 11 is connectable to the waste discharge outlet 32 ​​of the toilet body 3, and a cooperating portion 13 of the waste discharge pipe 11 cooperates with the switching assembly 2, thereby allowing the switching assembly 2 to connect or disconnect the waste discharge pipe 11. A second inlet end 121 of the water seal pipe 12 is connectable to the waste discharge pipe 11, and the connecting portion is located upstream of the cooperating portion 13, so that the water seal pipe 12 always connects to the waste discharge outlet 32 ​​of the toilet body 3. The highest point of the water seal pipe 12 is higher than the highest point of the waste discharge pipe 11, so that when the switching assembly 2 disconnects the waste discharge pipe 11, the water seal pipe 12 can seal the toilet body 3 with water to block out odors. When the switching assembly 2 connects the waste discharge pipe 11, the highest point of the waste discharge pipe 11 is lower than the highest point of the water seal pipe 12, so that the waste discharge pipe 11 can be used to discharge waste from the toilet, and the excrement in the toilet body 3 does not remain in the water seal pipe 12 but can be discharged through the waste discharge pipe 11.

[0025] The waste discharge device according to the embodiment of the present application achieves the water sealing function with the water-sealed pipe 12, achieves the waste discharge function with the waste discharge pipe 11, and enables the connection and disconnection of the waste discharge pipe 11 with the switch assembly 2, eliminating the need for a siphon waste discharge function, reducing noise during toilet flushing and ensuring clean removal of excrement from the toilet body 3. Furthermore, the piping assembly 1 of the waste discharge device can be molded separately from the toilet body 3, and then assembled and connected, which reduces the difficulty of the molding process of the toilet body 3 and reduces processing costs.

[0026] It should be understood that the second inlet end 121 of the water seal pipe 12 does not have to be connected to the waste discharge pipe 11, and the first inlet end 111 of the waste discharge pipe 11 and the second inlet end 121 of the water seal pipe 12 can be arranged in parallel, and by switching the switching assembly 2, the communication between the first inlet end 111 of the waste discharge pipe 11 and the waste discharge outlet 32, and the communication between the second inlet end 121 of the water seal pipe 12 and the waste discharge outlet 32 ​​can be achieved.

[0027] In some exemplary embodiments, as shown in FIGS. 11-12, the outlet end (ie, the second outlet end 122) of the water seal pipe 12 communicates with a portion of the waste discharge pipe 11 located downstream of the cooperating portion 13.

[0028] The portion of the second outlet end 122 of the water seal pipe 12 that communicates with the waste discharge pipe 11 is located downstream of the cooperating portion 13, and thus, when the switching assembly 2 closes the waste discharge pipe 11, the second outlet end 122 of the water seal pipe 12 maintains communication with the first outlet end 112 of the waste discharge pipe 11, so that excess water in the toilet body 3 can overflow from the waste discharge pipe 11 after passing through the water seal pipe 12, and the water in the toilet body 3 can be maintained on the water seal surface, meeting the water seal requirement.

[0029] Of course, the second outlet end 122 of the water seal pipe 12 may not be configured to communicate with the part of the waste discharge pipe 11 located downstream of the associated part 13, and the second outlet end 122 of the water seal pipe 12 may be configured to be suspended, which does not affect the water sealing function of the water seal pipe 12.

[0030] In some exemplary embodiments, as shown in FIGS. 11-12, the second outlet end 122 of the water seal pipe 12 is located adjacent to the first outlet end 112 of the waste discharge pipe 11.

[0031] The second outlet end 122 of the water seal pipe 12 may be located close to the first outlet end 112 of the waste discharge pipe 11. Because the first outlet end 112 of the waste discharge pipe 11 is located low, the second outlet end 122 of the water seal pipe 12 is located low, and there is a large height difference between the second outlet end 122 and the highest point of the water seal pipe 12. When the switching assembly 2 connects the waste discharge pipe 11 to discharge waste, a siphon may occur in the water seal pipe 12, which may lead to the intrusion of foreign matter into the water seal pipe 12. Therefore, a filter mesh 16 is installed at the second inlet end 121 of the water seal pipe 12 to ensure that water does not overflow from the water seal while preventing foreign matter from entering the water seal pipe 12 and clogging it.

[0032] In this exemplary embodiment, as shown in Figures 5 to 12, the piping assembly 1 includes a piping body 14 and a U-shaped pipe 15, and the piping body 14 is provided with a sewage discharge pipe 11, a first water seal sub-pipe 143, a first port 141 and a second port 142, the first port 141 is connected to a portion of the sewage discharge pipe 11 located upstream of the cooperating portion 13, and the second port 142 is connected to a portion of the sewage discharge pipe 11 located downstream via the first water seal sub-pipe 143, and both ends of the U-shaped pipe 15 are connected to the first port 141 and the second port 142, respectively, and the pipe in the U-shaped pipe 15 and the first water seal sub-pipe 143 form the water seal pipe 12.

[0033] In the piping assembly 1, a sewage discharge pipe 11 and a first water seal sub-pipe 143 are provided in a piping main body 14, and the piping main body 14 is further provided with a first port 141 communicating with a portion of the sewage discharge pipe 11 located upstream of the cooperating portion 13 and a second port 142 communicating with one end of the first water seal sub-pipe 143, and the other end of the first water seal sub-pipe 143 is communicating with a portion of the sewage discharge pipe 11 located downstream of the cooperating portion 13, so that the second port 142 is connected to the sewage discharge pipe 11 via the first water seal sub-pipe 143. The U-shaped pipe 15 communicates with the part of the pipe 11 located downstream of the cooperating part 13, and both ends of the U-shaped pipe 15 communicate with the first port 141 and the second port 142, respectively, so that the pipe inside the U-shaped pipe 15 communicates with the first water seal sub-pipe 143 to form the water seal pipe 12, which communicates with the sewage discharge pipe 11, and the communicating parts of the water seal pipe 12 and the sewage discharge pipe 11 are located upstream and downstream of the cooperating part 13, respectively, so that the water seal function and water overflow function of the water seal pipe 12 are not affected.

[0034] As shown in Figure 6, the first port 141 and the second port 142 of the pipe body 14 are located at the top of the pipe body 14, the U-shaped pipe 15 is installed in an inverted position, and both downward ends of the U-shaped pipe 15 are connected to the first port 141 and the second port 142, respectively. The U-shaped pipe 15 may be a hose, and both ends of the U-shaped pipe 15 are inserted into the outside of the first port 141 and the second port 142 with a tight fit, thereby realizing a sealed connection between the U-shaped pipe 15 and the first port 141 and between the U-shaped pipe 15 and the second port 142 and preventing water leakage from the connection points. As shown in Figures 10 and 11, the entire first water seal sub-pipe 143 is installed vertically, and the portion where the first water seal sub-pipe 143 communicates with the sewage discharge pipe 11 is installed adjacent to the first outlet end 112 at the bottom of the sewage discharge pipe 11. The highest point of the inverted U-shaped pipe 15 forms the highest point of the water seal pipe 12 (i.e., the overflow point of the water seal pipe 12), which is higher than the highest point of the waste discharge pipe 11 in the piping main body 14 and higher than the height of the water seal surface H of the toilet main body 3 (see Figure 4), thereby realizing the water seal function of the water seal pipe 12.

[0035] As shown in Figures 9, 11 and 12, the waste discharge pipe 11 includes a first waste discharge sub-pipe 113 installed horizontally and a second waste discharge sub-pipe 114 installed vertically, one end of the first waste discharge sub-pipe 113 and one end of the second waste discharge sub-pipe 114 are connected in an inverted L-shape, the other end of the first waste discharge sub-pipe 113 forms a first inlet end 111 of the waste discharge pipe 11, and the other end of the second waste discharge sub-pipe 114 forms a first outlet end 112 of the waste discharge pipe 11, and the first waste discharge sub-pipe 113 is inclined downward along the flow direction of the flush water in the waste discharge pipe 11, so that waste in the toilet body 3 is discharged through the waste discharge pipe 11 under the action of the flush water.

[0036] The first port 141 communicates with the first sewage discharge sub-pipe 113, and the second port 142 communicates with the second sewage discharge sub-pipe 114 via the first water seal sub-pipe 143. A cooperating section 13 in the sewage discharge pipe 11 may be installed at the connection between the first sewage discharge sub-pipe 113 and the second sewage discharge sub-pipe 114, so that the first port 141 is located upstream of the cooperating section 13, the connection section between the first water seal sub-pipe 143 and the second sewage discharge sub-pipe 114 is located downstream of the cooperating section 13, and the second inlet end 121 (the end where the U-shaped pipe 15 and the first port 141 are connected) and the second outlet end 122 (the end where the first water seal sub-pipe 143 and the second sewage discharge sub-pipe 114 are connected) of the water seal pipe 12 are located upstream and downstream of the cooperating section 13, respectively.

[0037] The piping body 14 may have an integrally molded structure. As shown in Figures 6, 11 and 12, in order to facilitate molding, an opening communicating with the outside of the piping body 14 is provided in the middle of the first water seal sub-pipe 143, and the opening is sealed by a plug 18.

[0038] In another exemplary embodiment, the second outlet end 122 of the water seal conduit 12 is located adjacent to the cooperating part 13, as shown in FIGS.

[0039] The second outlet end 122 of the water seal pipe 12 may be located close to the cooperating portion 13 in the waste discharge pipe 11. Because the cooperating portion 13 is located higher than the first outlet end 112 of the waste discharge pipe 11 and the second outlet end 122 of the water seal pipe 12 is located higher, when the switching assembly 2 connects the waste discharge pipe 11 to discharge waste, siphoning does not occur in the water seal pipe 12 and foreign matter does not enter the water seal pipe 12. Therefore, there is no need to install a filter mesh 16 at the second inlet end 121 of the water seal pipe 12. Alternatively, a filter mesh 16 may be installed at the second inlet end 121 of the water seal pipe 12 to prevent foreign matter from entering the water seal pipe 12 and clogging it.

[0040] In this exemplary embodiment, as shown in Figures 13 to 15, the piping assembly 1 includes a piping body 14 and a U-shaped pipe 15, the piping body 14 is provided with a waste discharge pipe 11, a first port 141 and a second port 142 communicating with the waste discharge pipe 11, and the first port 141 and the second port 142 are located upstream and downstream of the cooperating part 13, respectively, both ends of the U-shaped pipe 15 are communicated with the first port 141 and the second port 142, respectively, and the pipe inside the U-shaped pipe 15 forms a water-sealed pipe 12.

[0041] In the piping assembly 1, a sewage discharge pipeline 11 is provided within the piping body 14, and the piping body 14 is further provided with a first port 141 and a second port 142 located respectively upstream and downstream of the cooperating section 13. Both ends of the U-shaped pipe 15 are connected to the first port 141 and the second port 142, respectively, so that the water seal pipeline 12 formed within the U-shaped pipe 15 is connected to the sewage discharge pipeline 11 via the first port 141 and the second port 142, and the connecting portions between the U-shaped pipe 15 and the sewage discharge pipeline 11 are located respectively upstream and downstream of the cooperating section 13, which does not affect the water seal and water overflow functions of the water seal pipeline 12.

[0042] As shown in Figure 15, the first port 141 and the second port 142 of the pipe body 14 are located at the top of the pipe body 14, and the U-shaped pipe 15 is installed in an inverted position, with both downward ends of the U-shaped pipe 15 connected to the first port 141 and the second port 142, respectively. The U-shaped pipe 15 may be a hose, and both ends of the U-shaped pipe 15 are inserted into the outside of the first port 141 and the second port 142 with a tight fit, thereby achieving a sealed connection between the U-shaped pipe 15 and the first port 141 and between the U-shaped pipe 15 and the second port 142 and preventing water leakage from the connection points. The highest point of the inverted U-shaped pipe 15 forms the highest point of the water seal pipe 12, which is higher than the highest point of the waste discharge pipe 11 in the pipe body 14 and higher than the height of the water seal surface H of the toilet body 3, thereby realizing the water seal function of the water seal pipe 12.

[0043] As shown in FIG. 15, the sewage discharge pipeline 11 includes a first sewage discharge sub-pipe 113 installed horizontally and a second sewage discharge sub-pipe 114 installed vertically, the first sewage discharge sub-pipe 113 and the second sewage discharge sub-pipe 114 are connected in an inverted L-shape, and the first port 141 and the second port 142 are both connected to the first sewage discharge sub-pipe.

[0044] In the waste discharge pipe 11, one end of the first waste discharge sub-pipe 113 installed horizontally and one end of the second waste discharge sub-pipe 114 installed vertically are connected in an inverted L shape, the other end of the first waste discharge sub-pipe 113 forms the first inlet end 111 of the waste discharge pipe 11, and the other end of the second waste discharge sub-pipe 114 forms the first outlet end 112 of the waste discharge pipe 11, and the first waste discharge sub-pipe 113 is inclined downward along the flow direction of the flush water in the waste discharge pipe 11, so that waste in the toilet body 3 is discharged through the waste discharge pipe 11 under the action of the flush water.

[0045] The first port 141 and the second port 142 connected to the U-shaped pipe 15 are both connected to the first sewage discharge sub-pipe 113, and the cooperating part 13 is located between the first port 141 and the second port 142, so that the first port 141 and the second port 142 are located upstream and downstream of the cooperating part 13, respectively.

[0046] The piping body 14 may be of one piece molded construction.

[0047] In some exemplary embodiments, the switching assembly includes a switching component configured to be rotatable or translatable to switch between a first position and a second position, the switching component disconnecting the waste discharge line when in the first position and the switching component connecting the waste discharge line when in the second position.

[0048] The switching part of the switching assembly 2 can rotate forward and backward or move back and forth in translation, thereby allowing the switching part to switch between a first position and a second position. When the switching part moves to the first position, the waste discharge pipeline 11 can be cut off, and at this time the water seal pipeline 12 can perform water sealing. When the switching part moves to the second position, the waste discharge pipeline 11 is connected, allowing waste discharge.

[0049] In some exemplary embodiments, as shown in Figures 6, 9, 11-12, and 15, a mounting cavity 17 is provided within the piping assembly 1 for mounting the switching assembly 2, and the switching assembly 2 includes a reciprocating sealing piston 21.

[0050] The cooperating portion 13 is an annular seal portion, and the seal piston 21 is configured to abut against the annular seal portion to cut off the waste discharge pipe 11, or to separate from the annular seal portion to allow the waste discharge pipe 11 to communicate.

[0051] A mounting cavity 17 is provided within the piping assembly 1, and the switching assembly 2 can be mounted therein. The mounting cavity 17 can communicate with the waste discharge pipeline 11, allowing the seal piston 21 of the switching assembly 2 to move into the waste discharge pipeline 11, with the edge region of the end face of the seal piston 21 abutting against the annular cooperating portion 13, realizing sealing cooperation between the seal piston 21 and the cooperating portion 13 to disconnect the waste discharge pipeline 11, and at this time, the water seal pipeline 12 can be water sealed. The seal piston 21 can also move until its end face separates from the annular cooperating portion 13, at which time the waste discharge pipeline 11 is connected and waste discharge can be achieved.

[0052] In some exemplary embodiments, the communication between the mounting cavity 17 and the waste discharge line 11 is located downstream of the annular seal. The sealing piston 21 is configured to seal the mounting cavity 17 when separated from the annular seal, thereby separating the mounting cavity 17 from the waste discharge line 11.

[0053] After separating from the annular cooperating part 13, the sealing piston 21 can move until it seals the mounting cavity 17, thereby separating the mounting cavity 17 from the waste discharge pipe 11 and preventing the flow of wastewater into the mounting cavity 17 during waste discharge. And / or, a sealing part may be provided in the mounting cavity 17 to prevent wastewater in the waste discharge pipe 11 from flowing into the mounting cavity 17 and causing leakage at the mounting cavity 17.

[0054] 23 , the switching assembly 2 may include a ball valve 29, which includes a passageway 291 and a rotatable spool 292. The spool 292 is configured to control the connection and disconnection of the passageway 291 by rotation. In this case, the cooperating part 13 cooperating with the switching assembly 2 may be a mounting part of the ball valve 29, and the ball valve 29 seals and cooperates with the cooperating part 13 to prevent leakage through a gap between the ball valve 29 and the cooperating part 13. Portions of the waste discharge pipeline 11 located on both sides of the cooperating part 13 (i.e., portions located upstream and downstream of the cooperating part 13) may communicate with both ends of the passageway 291. The rotation of the spool 292 controls the connection and disconnection of the passageway 291 in the ball valve 29, which in turn controls the connection and disconnection of the waste discharge pipeline 11 by communication and disconnection of the passageway 291.

[0055] In some exemplary embodiments, as shown in Figures 9, 11-12, and 15, the waste discharge pipe 11 has an inverted L-shape, the mounting cavity 17 and the first waste discharge sub-pipe 113 are respectively installed on both sides of the second waste discharge sub-pipe 114, and the communication portions of the first waste discharge sub-pipe 113 and the second waste discharge sub-pipe 114 also communicate with the mounting cavity 17, and the central axis of the mounting cavity 17 may be collinear with the central axis of the first waste discharge sub-pipe 113, so that the mounting cavity 17, the first waste discharge sub-pipe 113, and the second waste discharge sub-pipe 114 as a whole form a substantial T-shape.

[0056] In some exemplary embodiments, as shown in Figures 6, 9, 11 to 12, and 15, the sealing piston 21 includes a sealing rubber pad 211 and a rubber pad bracket 212, and the sealing rubber pad 211 is attached to the rubber pad bracket 212, and the sealing rubber pad 211 is configured to abut against the cooperating part 13 to cut off the waste discharge pipeline 11, or to be separated from the cooperating part 13 to allow the waste discharge pipeline 11 to communicate.

[0057] In the sealing piston 21, the sealing rubber pad 211 is attached to the rubber pad bracket 212, and the rubber pad bracket 212 can support the elastic sealing rubber pad 211, and the sealing rubber pad 211 can abut against the cooperating part 13 to cooperate with it, or can be separated from the cooperating part 13, thereby disconnecting or connecting the waste discharge pipe 11 and switching the waste discharge device between the waste discharge and water sealing functions.

[0058] In some exemplary embodiments, as shown in Figures 6, 9, 11-12, and 15, the rubber pad bracket 212 is cylindrical with one open end and one closed end, and the sealing rubber pad 211 is fitted onto the outside of the closed end of the rubber pad bracket 212.

[0059] The rubber pad bracket 212 is cylindrical with one open end and one closed end, and the sealing rubber pad 211 is fitted onto the outside of the closed end of the rubber pad bracket 212, so that the rubber pad bracket 212 effectively supports the sealing rubber pad 211, and when the sealing rubber pad 211 abuts against and cooperates with the cooperating part 13, the sealing rubber pad 211 is pressed by the rubber pad bracket 212 and the cooperating part 13, ensuring a sealing cooperation between the sealing rubber pad 211 and the cooperating part 13. A sealing part (e.g., an O-ring) to prevent leakage from the mounting cavity 17 after the mounting cavity 17 is connected to the waste discharge pipe 11 may be installed between the outer wall surface of the rubber pad bracket 212 and the inner wall surface of the mounting cavity 17.

[0060] In some exemplary embodiments, the switching assembly 2 further includes a drive assembly that is connected to the sealing piston 21 and is capable of reciprocating the sealing piston 21 .

[0061] The drive assembly can be connected to the rubber pad bracket 212 of the seal piston 21, and the drive assembly reciprocates the rubber pad bracket 212, thereby moving the seal rubber pad 211, so that the seal rubber pad 211 can abut against the cooperating part 13 to cooperate with it, or separate from the cooperating part 13, thereby achieving disconnection or communication of the waste discharge pipeline 11.

[0062] In some exemplary embodiments, as shown in Figures 6, 9, 11-12, and 15, the drive assembly includes an electric telescopic rod 22, which includes a telescopic end, which can move back and forth, and which can be connected to a sealing piston 21.

[0063] The telescopic end of the electric telescopic rod 22 can extend into the tubular rubber pad bracket 212 and is fixedly connected to the rubber pad bracket 212 via a fixing block 221. As a result, when the telescopic end of the electric telescopic rod 22 performs telescopic movement, the rubber pad bracket 212 and the sealing rubber pad 211 attached to the rubber pad bracket 212 move back and forth, and the sealing rubber pad 211 and the cooperating part 13 come into contact with each other or separate from each other.

[0064] As shown in Figures 6, 9, 11-12, and 15, the switching assembly 2 further includes an end cap 23, which can be fixedly connected to the pipe body 14 and closes the opening at one end of the mounting cavity 17 that is away from the waste discharge pipe 11, the electric telescopic rod 22 can be attached to the end cap 23, and the telescopic end of the electric telescopic rod 22 can be fixedly connected to the rubber pad bracket 212.

[0065] When the toilet activates the flushing function, the toilet pump 5 (see below for details) draws up water from the tank 4 (see below for details), and the water flows through the rim water inlet 31 (see below for details) into the toilet bowl, flushing it. At the same time, the electric telescopic rod 22 retracts, opening the waste discharge pipe 11, realizing the functions of flushing the toilet bowl and flushing waste discharge.

[0066] When the waste discharge is completed, the electric telescopic rod 22 extends, the sealing rubber pad 211 closes the waste discharge pipe 11, water continues to flow in from the rim water supply port 31, and excess water overflows from the water seal pipe 12. At the same time, the overflow point of the water seal pipe 12 is above the water seal surface H, and sufficient water to meet the water seal requirement is ensured in the toilet bowl.

[0067] In some other exemplary embodiments, as shown in Figures 16 and 17, the drive assembly includes a drive element, a gear 261 and a rack 262, the drive assembly is connected to the gear 261 and can rotate the gear 261, the gear 261 meshes with and cooperates with the rack 262, and the rack 262 is connected to the seal piston 21.

[0068] The drive element connects the seal piston 21 with the rubber pad bracket 212 through a transmission mechanism consisting of a gear 261 and a rack 262, so that when the drive element rotates the gear 261 forward or backward, the rack 262 moves the rubber pad bracket 212 and the seal rubber pad 211 attached to the rubber pad bracket 212 back and forth, thereby realizing the abutment, cooperation, or separation of the seal rubber pad 211 and the cooperating part 13.

[0069] In this solution, a reversible gear 261 is used to cooperate with a rack 262 attached to the rubber pad bracket 212 to transmit force, causing the rubber pad bracket 212 to move back and forth, thereby opening and closing the waste discharge pipe 11. When the gear 261 rotates in the reverse direction (or forward direction), the rubber pad bracket 212 moves back into the mounting cavity 17, opening the waste discharge pipe 11 and realizing the waste discharge function. When the gear 261 rotates in the forward direction (or reverse direction), the rubber pad bracket 212 moves out of the mounting cavity 17 and protrudes, closing the waste discharge pipe 11 and realizing the water sealing function.

[0070] The drive element may be a manual drive element or an electrically driven drive element (such as a motor).

[0071] The rack 262 and the rubber pad bracket 212 may be separate structures that are fixedly connected, or as shown in Figures 16 and 17, the rack 262 and the rubber pad bracket 212 may be an integrated structure to reduce the number of parts and simplify the assembly process.

[0072] In yet another exemplary embodiment, as shown in FIGS. 18 to 22 , the switching assembly 2 further includes a cylindrical body and an elastic member 24, the cylindrical body is fixed within the mounting cavity 17 and cooperates with the seal piston 21 to form a seal cavity 28, the seal cavity 28 is configured to contain a fluid and have a fluid inlet and outlet, and the elastic member 24 is disposed between the cylindrical body and the seal piston 21.

[0073] The seal piston 21 is configured so that it can be in one of abutment and separation with the cooperating part 13 under the action of the elastic part 24, and can also be in the other of abutment and separation with the cooperating part 13 by moving against the elastic force of the elastic part 24 under the action of fluid entering the seal cavity 28.

[0074] The switching assembly 2 includes a seal piston 21, a cylinder, and an elastic element 24. The cylinder is fixed in the mounting cavity 17 of the piping assembly 1. The seal piston 21 is reciprocatingly displaceable within the mounting cavity 17. The cylinder can cooperate with the cylindrical seal piston 21 to form a seal cavity 28. The seal cavity 28 has a fluid inlet and outlet, and a fluid (e.g., water, air, etc.) having a certain pressure can enter or be discharged from the seal cavity 28 through the fluid inlet and outlet. The elastic element 24 is further installed between the cylinder and the seal piston 21. In this way, the seal piston 21 is acted upon by the elastic force of the elastic element 24 and the pressure of the fluid in the seal cavity 28. When the elastic force of the elastic part 24 is greater than the pressure of the fluid, the sealing piston 21 moves in one direction until it abuts against the cooperating part 13 and cooperates with it (or separates from it), and when the pressure of the fluid is greater than the elastic force of the elastic part 24, the sealing piston 21 moves in the opposite direction until it separates from the cooperating part 13 (or abuts against and cooperates with it).

[0075] In this exemplary embodiment, as shown in Figures 18 to 22, the fluid inlet and outlet may include a fluid inlet 231 and a fluid outlet 271, and the switching assembly 2 may further include a pressure relief line 251 and a pressure relief valve 252, both ends of the pressure relief line 251 respectively communicating with the fluid outlet 271 and a portion of the waste discharge line 11 located downstream of the associated portion 13, and the pressure relief valve 252 is installed in the pressure relief line 251 to control the communication and disconnection of the pressure relief line 251.

[0076] The seal cavity 28 is provided with a fluid inlet 231 and a fluid outlet 271. Fluid can enter the seal cavity 28 through the fluid inlet 231, increasing the fluid pressure to be greater than the elastic force of the elastic element 24. The fluid is discharged from the seal cavity 28 through the fluid outlet 271, reducing the fluid pressure to be less than the elastic force of the elastic element 24, allowing the seal piston 21 to reciprocate under the action of the fluid pressure and the elastic force of the elastic element 24. A pressure relief line 251 is connected between the fluid outlet 271 and a portion of the waste discharge line 11 located downstream of the cooperating part 13, so that the fluid discharged from the seal cavity 28 through the fluid outlet 271 is discharged to the waste discharge line 11 through the pressure relief line 251, thereby realizing pressure relief of the seal cavity 28. A pressure relief valve 252 is provided in the pressure relief line 251 to control the connection and disconnection of the pressure relief line 251, and thus to control the discharge of the fluid in the seal cavity .

[0077] 18 to 22, the cylindrical body includes an end cap 23 and a fixed seat 27. The fixed seat 27 is cylindrical and open at both ends. The end cap 23 is fixed to one opening of the fixed seat 27 to seal the opening. The cylindrical rubber pad bracket 212 of the seal piston 21 extends into the fixed seat 27 from the opening at the other end and is movable relative to the fixed seat 27. A sealing element (e.g., an O-ring) is provided between the fixed seat 27 and the rubber pad bracket 212, and the end cap 23, fixed seat 27, and rubber pad bracket 212 cooperate to form a seal cavity 28. A fluid inlet 231 is provided in the end cap 23, and a fluid outlet 271 is provided at one end of the fixed seat 27 closest to the end cap 23. The elastic element 24, which may be a spring, is installed between the fixed seat 27 and the rubber pad bracket 212.

[0078] In this solution, rubber pad bracket 212, end cap 23, fixed seat 27, and sealing components are assembled to form a seal cavity 28 with a cavity in which rubber pad bracket 212 can slide. Pressurized water is injected into seal cavity 28 through fluid inlet 231 of end cap 23, and the elastic properties of the spring and the opening and closing pressure relief function of pressure relief valve 252 are used to realize the reciprocating movement of rubber pad bracket 212, thereby opening and closing sewage discharge pipe 11.

[0079] When the waste discharge function is activated, the pressure relief valve 252 opens, reducing the water pressure in the seal cavity 28, causing the rubber pad bracket 212 to contract due to the elastic force of the spring, opening the waste discharge pipe 11 and discharging the waste. When the waste discharge function is turned off, the pressure relief valve 252 closes, and pressurized water injected from the fluid inlet 231 enters the seal cavity 28, pushing and moving the rubber pad bracket 212, compressing the spring, pushing out the rubber pad bracket 212 and pulling the sealing rubber pad 211 to tightly press the cooperating part 13, thereby achieving a sealing effect.

[0080] As shown in Figures 1 to 22, an embodiment of the present application further provides a toilet, comprising a toilet body 3 and a toilet waste discharge device according to any of the above embodiments, the toilet body 3 having a toilet bowl and a waste discharge outlet 32, the waste discharge outlet 32 ​​being installed at the bottom of the toilet bowl and communicating with the toilet bowl, and the first inlet end 111 of the waste discharge pipe 11 of the waste discharge device and the second inlet end 121 of the water-sealed pipe 12 both communicating with the waste discharge outlet 32.

[0081] 1 to 4, in some exemplary embodiments, the toilet further comprises a tank 4 and a pump 5, the toilet body 3 further comprises a rim water inlet 31, the rim water inlet 31 is installed on the top of the toilet bowl, the suction end of the pump 5 is connected to the tank 4, and the discharge end of the pump 5 is connected to the rim water inlet 31, the pump 5 sends water from the tank 4 to the rim water inlet 31, and the water sprayed from the rim water inlet 31 flushes the toilet bowl. The first outlet end 112 of the waste discharge pipe 11 can be connected to a sewer pipe, and waste is discharged through the sewer pipe.

[0082] Of course, the toilet may be configured not to include the tank 4.

[0083] In some exemplary embodiments, the toilet body 3 may not have a jet located at the bottom of the bowl to reduce noise when the toilet is flushed.

[0084] In summary, the toilet and waste discharge device according to the embodiment of the present application utilizes a dual waterway system to separate the waste discharge pipe and the water seal pipe, simultaneously fulfilling the waste discharge and water seal functions, while reducing the molding process of the toilet body and reducing costs. The switching assembly controls the path of the waste discharge pipe to achieve controlled waste discharge, making the waste discharge speed faster and smoother. The toilet body does not have a jet nozzle at the bottom, reducing water spray noise.
