Description

Technical Field

[0001] The utility model relates to the technical field of toilets, in particular to a sewage discharge device and a toilet of a toilet. Background Art

[0002] Basically, the traditional siphon toilet cleans the ceramic bowl surface of the toilet by discharging water through the brush ring opening, discharges the excrement in the toilet by spraying water through the spray opening, and at the same time utilizes the S-shaped pipeline of the ceramic itself to generate a siphon function to realize the sewage discharge function. Since the sewage discharge of the siphon toilet mainly uses the large water flow spraying of the spray opening to spray the excrement into the S-shaped pipeline, a large flushing noise will be generated during sewage discharge, and the sewage discharge path is tortuous, resulting in insufficient sewage discharge capacity. When the excrement is large and there is a lot of it, it cannot be discharged completely. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a sewage discharge device and a toilet of a toilet, aiming to reduce the flushing noise during sewage discharge of the toilet and improve the sewage discharge capacity of the toilet.

[0011] In one embodiment, the sewage discharging device of the toilet further includes a lower sewage pipe disposed below the pipe body. The outlet ends of the main sewage pipe and the auxiliary sewage pipe are respectively communicated with the lower sewage pipe.

[0012] In one embodiment, the lower sewage pipe is integrally formed with the toilet body;

[0013] Alternatively, the sewage discharging device of the toilet further includes a box body, which is used to enclose the pipe body with the toilet body to form an installation space for accommodating the pipe body, and at least part of the lower sewage pipe is formed by the box body.

[0014] In one embodiment, the switching mechanism includes:

[0015] A plugging member, which is movably installed on the pipe body. The plugging member has an open position for conducting the main sewage pipe and a plugging position for blocking the main sewage pipe; and

[0016] A driving assembly, which is drivingly connected to the plugging member and is used to drive the plugging member to switch between the open position and the plugging position.

[0017] In one embodiment, the switching mechanism further includes a sealing member, which is disposed on the plugging member and / or the pipe body. When the plugging member is in the plugging position, the sealing member is used to seal and connect the plugging member and the pipe body.

[0018] In one embodiment, the plugging member is slidably installed on the pipe body. The plugging member has a plurality of tooth portions arranged along its sliding direction. The driving assembly includes a first driving member and a gear drivingly connected to the first driving member. The gear meshes with the tooth portions of the plugging member, and the first driving member is used to drive the gear to rotate so as to drive the plugging member to slide and switch between the open position and the plugging position.

[0019] In one embodiment, the plugging member is rotatably connected to the pipe body through a rotating shaft;

[0020] The driving assembly includes a second driving member and a coupling, wherein the output end of the second driving member is connected to the rotating shaft through the coupling, and the second driving member is used to drive the rotating shaft to rotate, so as to drive the blocking member to flip and switch between the open position and the blocking position;

Among them, the main sewage discharge pipe is arranged at the bottom of the pipeline main body, and sewage discharge is relatively easy. The inlet end of the auxiliary sewage discharge pipe is higher than that of the main sewage discharge pipe, so that a certain water pressure needs to be applied to discharge sewage through the auxiliary sewage discharge pipe. In this way, the main sewage discharge pipe discharging downward directly can be used as the main sewage discharge method, the auxiliary sewage discharge pipe discharging sewage can be used as the auxiliary sewage discharge method, and the combined sewage discharge of the main sewage discharge pipe and the auxiliary sewage discharge pipe can also be realized. Since the sewage discharge device of this technical solution uses the main sewage discharge pipe discharging downward directly as the main sewage discharge method, when discharging sewage, under the action of gravity and the upper part of the toilet replenishing water, the sewage in the sewage holding cavity can be quickly discharged through the main sewage discharge pipe.

The structure of the main sewage discharge pipe can be designed to be simpler, the pipe diameter can be designed to be larger, so that the sewage discharge path is shorter, the sewage discharge speed is faster than that of the siphon sewage discharge, and the sewage discharge capacity is stronger. And in some scenarios, the combined sewage discharge of the main sewage discharge pipe and the auxiliary sewage discharge pipe can also be used to further improve the sewage discharge capacity of the toilet.

[0053] Traditional siphon toilets basically clean the ceramic bowl surface of the toilet by discharging water through the brush ring opening, discharge the excrement in the toilet by spraying water through the spray opening, and at the same time utilize the S-shaped pipeline of the ceramic itself to generate a siphon function to achieve the sewage discharge function. Since the sewage discharge of the siphon toilet mainly uses the large water flow spraying of the spray opening to spray the excrement into the S-shaped pipeline, a relatively large flushing noise will be generated during sewage discharge; and because the siphon effect needs to be utilized, the diameter of the S-shaped pipeline needs to be designed to be relatively small, and the sewage discharge path is tortuous, resulting in insufficient sewage discharge capacity, and the problem that when the excrement is large and numerous, it cannot be discharged completely. In addition, the S-shaped pipeline of the traditional siphon toilet usually needs to be integrally formed with the ceramic toilet body, with complex manufacturing processes and high costs; and the siphon toilet is also affected by installation conditions such as bathroom deflectors and other special-shaped pipelines, resulting in poor siphon and drainage, and it cannot be installed in many environments.

[0054] The present utility model provides a sewage discharge device for a toilet. By optimizing the structure of the sewage discharge device, the flushing noise during toilet sewage discharge can be reduced, and the sewage discharge capacity of the toilet can be improved. Moreover, it can also simplify the manufacturing process of the toilet to a certain extent, reduce costs, and the installation conditions are not restricted, which can improve the installation convenience of the toilet.

[0055] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the sewage discharge device of the toilet includes a pipeline main body 21 and a switching mechanism 22. The pipeline main body 21 has a sewage discharge port 211 for communicating with the sewage holding cavity 101 of the toilet body 10, and a main sewage pipeline 212 and an auxiliary sewage pipeline 213 respectively communicating with the sewage discharge port 211. The main sewage pipeline 212 is located at the bottom of the pipeline main body 21, and the inlet end of the auxiliary sewage pipeline 213 is arranged higher than the main sewage pipeline 212; the switching mechanism 22 is used to conduct or cut off the main sewage pipeline 212, so that the sewage discharge device of the toilet has at least a main sewage discharge state of discharging sewage through the main sewage pipeline 212, an auxiliary sewage discharge state of discharging sewage through the auxiliary sewage pipeline 213, and a combined sewage discharge state of discharging sewage through the main sewage pipeline 212 and the auxiliary sewage pipeline 213 at the same time.

[0056] The sewage discharge device of the toilet (hereinafter referred to as the sewage discharge device) can be applied to the toilet. For example, the toilet includes a toilet body 10 and a sewage discharge device. The toilet body 10 can be made of ceramic material. The toilet body 10 has a sewage holding cavity 101. The sewage discharge port 211 of the sewage discharge device is communicated with the sewage holding cavity 101. The toilet body 10 can also be provided with a flushing device for flushing water into the sewage holding cavity 101, and a toilet cover assembly 30 for covering the top opening of the sewage holding cavity 101, etc. During sewage discharge, the flushing device can be used to flush the sewage holding cavity 101 of the toilet, so that the sewage in the sewage holding cavity 101 can enter the sewage discharge device from the sewage discharge port 211, and the sewage discharge device is used to discharge the sewage into the sewer system, thereby realizing the sewage discharge function of the toilet.

[0057] In this embodiment, the sewage discharge device can be arranged inside the toilet body 10. The sewage discharge device includes a pipeline main body 21 and a switching mechanism 22. The pipeline main body 21 constructs a main sewage discharge pipeline 212 and an auxiliary sewage discharge pipeline 213 for sewage discharge. The switching mechanism 22 is used to realize the conduction or cut-off of the main sewage discharge pipeline 212. Among them, the pipeline main body 21 can be of an integral structure, or it can also be formed by splicing multiple main body parts. The pipeline main body 21 has a sewage discharge port 211, and the sewage discharge port 211 is communicated with the sewage holding cavity 101 of the toilet body 10, so that the sewage in the sewage holding cavity 101 can be discharged into the pipeline main body 21 through the sewage discharge port 211. The pipeline main body 21 also has a main sewage discharge pipeline 212 and an auxiliary sewage discharge pipeline 213, so that the sewage entering the pipeline main body 21 can be discharged through the main sewage discharge pipeline 212 and / or the auxiliary sewage discharge pipeline 213. Among them, the main sewage discharge pipeline 212 and the auxiliary sewage discharge pipeline 213 can be directly communicated with the sewer system in the bathroom, or they can also be indirectly communicated with the sewer system through the lower sewage discharge pipeline 24 arranged inside the toilet body 10, as long as sewage can be discharged. The main sewage discharge pipeline 212 is arranged at the bottom of the pipeline main body 21, that is, the installation position of the main sewage discharge pipeline 212 is relatively low, so that the sewage entering the pipeline main body 21 from the sewage discharge port 211 can be discharged along the main sewage discharge pipeline 212 under the action of gravity, and the sewage discharge is relatively easy, so it is the main sewage discharge method. The inlet end of the auxiliary sewage discharge pipeline 213 is arranged higher than the main sewage discharge pipeline 212, so that a certain water pressure needs to be applied to discharge sewage through the auxiliary sewage discharge pipeline 213, so it is an auxiliary sewage discharge method.

[0058] The switching mechanism 22 is used to conduct or cut off the main sewage discharge pipeline 212, so that the sewage discharge device can be switched between multiple states such as the main sewage discharge state, the auxiliary sewage discharge state, and the combined sewage discharge state. For example, as Figure 4 shown, when the main sewage discharge pipeline 212 is conducted, if the sewage discharge pressure is relatively small, the sewage in the sewage holding cavity 101 enters the pipeline main body 21 through the sewage discharge port 211 and is directly discharged downward through the main sewage discharge pipeline 212. At this time, the sewage discharge device is in the main sewage discharge state. When the main sewage discharge pipeline 212 is conducted, if the sewage discharge pressure is relatively large, most of the sewage in the sewage holding cavity 101 mainly enters the pipeline main body 21 and is directly discharged downward through the main sewage discharge pipeline 212, and at the same time, a small part of the sewage can also be discharged through the auxiliary sewage discharge pipeline 213. At this time, the sewage discharge device is in the combined sewage discharge state. As Figure 5As shown in the figure, when the main sewage discharge pipe 212 is blocked, after the sewage in the sewage storage cavity 101 enters the pipe body 21 through the sewage discharge port 211, as long as a certain sewage discharge pressure is applied, the sewage can also be discharged through the auxiliary sewage discharge pipe 213. At this time, the sewage discharge device is in the auxiliary sewage discharge state. In addition, in actual application scenarios, there may be situations such as the failure of the switching mechanism 22 or power failure, resulting in the inability to conduct the main sewage discharge pipe 212. At this time, the auxiliary sewage discharge pipe 213 can also be used for sewage discharge to ensure that the sewage discharge function of the toilet is not affected.

[0059] The technical solution of the present utility model constructs two parallel sewage discharge channels, namely the main sewage discharge pipe 212 and the auxiliary sewage discharge pipe 213, in the pipe body 21, and the main sewage discharge pipe 212 is conducted or blocked through the switching mechanism 22, so that the sewage discharge device can switch between multiple states such as the main sewage discharge state, the auxiliary sewage discharge state, and the combined sewage discharge state. Among them, the main sewage discharge pipe 212 is arranged at the bottom of the pipe body 21, and sewage discharge is relatively easy. The inlet end of the auxiliary sewage discharge pipe 213 is higher than the main sewage discharge pipe 212, so that a certain water pressure needs to be applied to discharge sewage through the auxiliary sewage discharge pipe 213. In this way, the main sewage discharge pipe 212 discharging vertically downward can be used as the main sewage discharge method, the auxiliary sewage discharge pipe 213 discharging sewage can be used as the auxiliary sewage discharge method, and at the same time, the combined sewage discharge of the main sewage discharge pipe 212 and the auxiliary sewage discharge pipe 213 can also be realized. Since the sewage discharge device of the present technical solution uses the main sewage discharge pipe 212 discharging vertically downward as the main sewage discharge method, during sewage discharge, under the action of gravity and the upper part of the toilet replenishing water, the sewage in the sewage storage cavity 101 can be quickly discharged through the main sewage discharge pipe 212. Since the main sewage discharge pipe 212 does not need to use the siphon effect for sewage discharge, the flushing noise of the toilet during sewage discharge can be reduced, and by using the direct discharge method of the main sewage discharge pipe 212 for sewage discharge, the structure of the main sewage discharge pipe 212 can be designed to be simpler, the pipe diameter can be designed to be larger, so that the sewage discharge path is shorter, the sewage discharge speed is faster than that of the siphon sewage discharge, and the sewage discharge capacity is stronger. And in some scenarios, the combined sewage discharge of the main sewage discharge pipe 212 and the auxiliary sewage discharge pipe 213 can also be used to further improve the sewage discharge capacity of the toilet.

[0060] In addition, for the sewage discharge device of the toilet in this embodiment, its main sewage discharge method is not the siphon type. When installing the toilet, there is no need to consider the influence of the installation conditions on whether the siphon can form a siphon negative pressure during sewage discharge. Therefore, there is no need to consider installation conditions such as a diverter or other special-shaped pipes, and its installation conditions are not restricted, which can improve the installation convenience. And during manufacturing, there is no need to integrally form an S-shaped elbow on the toilet body 10, which can simplify the manufacturing process and reduce costs.

[0061] Such as Figure 17As shown, in one embodiment, the auxiliary sewage pipe 213 has a water storage section. When the main sewage pipe 212 is blocked, water can be stored in the water storage section so that the sewage device of the toilet still has a water seal state forming a water seal at the sewage outlet 211.

[0062] In this embodiment, the auxiliary sewage pipe 213 has a water storage section, and the outlet height of the water storage section is generally higher than the sewage outlet 211. For example, the auxiliary sewage pipe 213 can be extended upward to form a water storage section, so that a certain amount of water can be stored in the water storage section of the auxiliary sewage pipe 213, so that a water seal can be formed at the sewage outlet 211. When sewage is not needed, the main sewage pipe 212 is blocked, the sewage discharge device is in a water seal state, and a certain amount of water will exist in the sewage chamber 101 of the toilet body 10 and the auxiliary sewage pipe 213, and the sewage outlet 211 can be sealed by water, thereby preventing the odor inside the sewage discharge device pipe and the bathroom pipe from being discharged into the toilet body 10 through the sewage outlet 211, so as to play a role in isolating the odor.

[0063] like Figure 3 and Figure 17 As shown, in some embodiments, the pipe body 21 also has a buffer chamber 214 connected to the sewage outlet 211, the buffer chamber 214 has a first diversion port connected to the main sewage pipe 212, and a second diversion port connected to the auxiliary sewage pipe 213, the first diversion port is located at the bottom of the buffer chamber 214, the second diversion port is arranged higher than the first diversion port, the main sewage pipe 212 is extended downward from the first diversion port, and the auxiliary sewage pipe 213 is extended upward from the second diversion port.

[0064] In this embodiment, the sewage outlet 211 is connected to the main sewage pipe 212 and the auxiliary sewage pipe 213 via the buffer chamber 214. When discharging sewage, the sewage in the sewage chamber 101 first enters the buffer chamber 214 from the sewage outlet 211, and then enters the main sewage pipe 212 from the first diversion port, or enters the auxiliary sewage pipe 213 from the second diversion port. The first diversion port is located at the bottom of the buffer chamber 214, and the main sewage pipe 212 can be a straight pipe extending downward from the first diversion port. When the main sewage pipe 212 is connected, the sewage in the buffer chamber 214 can be discharged directly downward from the first diversion port through the main sewage pipe 212 under the action of gravity. The second diversion port is higher than the first diversion port, and the auxiliary sewage pipe 213 extends upward from the second diversion port. In this way, when the main sewage pipe 212 is blocked and sewage does not need to be discharged, a certain amount of water can be stored in the auxiliary sewage pipe 213, so that a water seal is formed at the sewage port 211 to isolate the odor. When the main sewage pipe 212 is blocked and sewage needs to be discharged, a certain water pressure can also be applied, for example, water can be added to the sewage chamber 101, so that the water in the buffer chamber 214 can flow upward along the auxiliary sewage pipe 213 to its outlet end for discharge.

[0065] The main sewage pipe 212 is a straight pipe that discharges directly downward. When discharging sewage, the siphon effect is not required, so its inner diameter can be designed larger. Optionally, the inner diameter of the main sewage pipe 212 is not less than 55 millimeters. For example, the inner diameter of the main sewage pipe 212 (i.e., the inner diameter of the inner circle of the main sewage pipe 212) can be 55 millimeters, 60 millimeters, 65 millimeters, etc. In this embodiment, the larger inner diameter of the main sewage pipe 212 can correspondingly shorten the length of the main sewage pipe 212, making the sewage discharge path short, the sewage discharge time shorter than that of the siphon sewage discharge, the sewage discharge speed faster, and the sewage discharge capacity strong. When the excrement is large and numerous, it can also be discharged cleanly to ensure the sewage discharge effect.

[0066] To further improve the sewage discharge capacity of the toilet, as Figure 3 shown, in one embodiment, the sewage discharge device of the toilet further includes a siphon elbow 23 communicated with the outlet end of the auxiliary sewage pipe 213. The siphon elbow 23 has a suction pipe section that bends upward from the auxiliary sewage pipe 213, and a discharge pipe section that extends downward from one end of the suction pipe section away from the auxiliary sewage pipe 213.

[0067] In this embodiment, a siphon elbow 23 is connected to the outlet end of the auxiliary sewage pipe 213. The siphon elbow 23 is generally arranged in an S-shaped elbow. The outlet end of the siphon elbow 23 can be communicated with the lower sewage pipe 24 in the toilet body 10, or directly communicated with the sewer system. When the sewage discharge device is in the auxiliary sewage discharge state, the main sewage pipe 212 is cut off. At this time, water can be added to the sewage storage cavity 101 of the toilet body 10, and the sewage can also enter the siphon elbow 23 from the auxiliary sewage pipe 213 and then be discharged by the siphon elbow 23. Since the suction section of the siphon elbow 23 is bent upward, when discharging sewage, a negative pressure can be generated in the siphon elbow 23 to form a siphon, and the sewage can be discharged relatively cleanly, thereby further enhancing the effect of auxiliary sewage discharge and improving the sewage discharge capacity. Among them, the siphon elbow 23 can be integrally formed with the pipe body 21, or the siphon elbow 23 can also be separately designed from the pipe body 21 and then assembled.

[0068] Optionally, the siphon elbow 23 is detachably connected to the pipe body 21. In this way, the manufacturing process of the pipe body 21 and the siphon elbow 23 can be simplified, and it is also convenient for the replacement and maintenance of the pipe body 21 or the siphon elbow 23. For example, the siphon elbow 23 can be sleeved on the outer peripheral surface of the outlet end of the auxiliary sewage pipe 213 and fixed.

[0069] Of course, in some embodiments, the siphon elbow 23 can also be omitted, and the auxiliary sewage discharge pipe 213 can be directly used for sewage discharge. In this way, there is no need to add installation space for the siphon elbow 23 inside the toilet body 10, the length of the rear part of the toilet body 10 can be shortened, the overall length of the toilet body 10 can be shortened, and the material and manufacturing costs of the toilet body 10 can be reduced.

[0070] In one embodiment, the sewage discharge device of the toilet further includes a lower sewage discharge pipe 24 disposed below the pipe main body 21. The outlet ends of the main sewage discharge pipe 212 and the auxiliary sewage discharge pipe 213 are respectively communicated with the lower sewage discharge pipe 24.

[0071] In this embodiment, the lower sewage discharge pipe 24 is located below the pipe main body 21, while the main sewage discharge pipe 212 is located at the bottom of the pipe main body 21. In this way, the length of the main sewage discharge pipe 212 can be further shortened, and the sewage discharge path can be shortened. When the toilet discharges sewage, the sewage in the sewage storage cavity 101 can enter the pipe main body 21 and then enter the lower sewage discharge pipe 24 via the main sewage discharge pipe 212 and / or the auxiliary sewage discharge pipe 213, and then be discharged into the sewer system by the lower sewage discharge pipe 24. Optionally, the lower sewage discharge pipe 24 has a first access port communicated with the outlet end of the main sewage discharge pipe 212, and a second access port communicated with the outlet end of the auxiliary sewage discharge pipe 213. The lower sewage discharge pipe 24 further has a sewage discharge port communicated with the sewer system. When the outlet end of the auxiliary sewage discharge pipe 213 is connected with a siphon elbow 23, the outlet end of the siphon elbow 23 can be communicated with the lower sewage discharge pipe 24 via the second access port. Among them, the lower sewage discharge pipe 24 can be provided on the toilet body 10 and integrally provided with the toilet body 10, or can be separately provided as a single part or component.

[0072] As Figure 3 shown, in one embodiment, the lower sewage discharge pipe 24 is integrally formed on the toilet body 10. Among them, the toilet body 10 can be made of ceramic material. When manufacturing the ceramic body, the sewage storage cavity 101 and the lower sewage discharge pipe 24 can be integrally formed inside the toilet body 10. Optionally, the sewage storage cavity 101 is located at the top of the toilet body 10, the lower sewage discharge pipe 24 is located at the bottom of the toilet body 10, the pipe main body is installed inside the toilet body 10, the main sewage discharge pipe 212 extends in the vertical direction to communicate with the lower sewage discharge pipe 24, and the auxiliary sewage discharge pipe 213 can be communicated with the lower sewage discharge pipe 24 through the siphon elbow 23.

[0073] As Figure 17 shown, in one embodiment, the sewage discharge device of the toilet further includes a box body 25. The box body 25 is used to enclose with the toilet body 10 to form an installation space for accommodating the pipe main body 21, and at least part of the lower sewage discharge pipe 24 is formed by the box body 25.

[0074] In this embodiment, the box body 25 can be disposed inside the toilet body 10. The box body 25 and the toilet body 10 enclose an installation space for accommodating the pipeline main body 21, and at least part of the lower sewage discharge pipeline 24 is formed by the box body 25. In this way, the main sewage discharge pipeline 212 and the auxiliary sewage discharge pipeline 213 of the pipeline main body 21 can directly discharge sewage into the box body 25, and then be discharged to the sewer system in the bathroom through the lower sewage discharge pipeline 24. By accommodating the pipeline main body 21 in the box body 25, the odor at the sewage discharge port 211 can be isolated from the outside, and the sewage can be prevented from flowing out of the toilet and polluting the bathroom. Optionally, the box body 25 includes a first box body part 251 and a second box body part 252 that are spliced with each other. The first box body part 251 is located above the second box body part 252. The first box body part 251 and the toilet body 10 jointly enclose an installation space for installing the pipeline main body 21. The inner cavity of the lower box body 25 constructs a part of the lower sewage discharge pipeline 24, and the other part of the lower sewage discharge pipeline 24 can be formed by the toilet body 10, or a sewage discharge pipe can be directly connected to the outlet end of the lower sewage discharge pipeline 24 constructed by the lower box body 25. In addition, in this embodiment, due to the arrangement of the box body 25, it is not necessary to connect a siphon elbow 23 to the outlet end of the auxiliary sewage discharge pipeline 213. In this way, there is no need to increase the installation space for the siphon elbow 23 inside the toilet body 10, the length of the rear part of the toilet body 10 can be shortened, the overall length of the toilet body 10 can be shortened, and the material and manufacturing costs of the toilet body 10 can be reduced.

[0075] Based on the above embodiment, in some embodiments, the switching mechanism 22 includes a blocking member 221 and a driving assembly 222. The blocking member 221 is movably installed on the pipeline main body 21. The blocking member 221 has an open position for conducting the main sewage discharge pipeline 212 and a blocking position for blocking the main sewage discharge pipeline 212; the driving assembly 222 is drivingly connected to the blocking member 221 and is used to drive the blocking member 221 to switch between the open position and the blocking position.

[0076] In this embodiment, the plugging member 221 is movably mounted on the pipe body 21 by means including but not limited to sliding installation and rotational installation. The driving assembly 222 is configured to drive the plugging member 221 to perform linear motion, curvilinear motion, flipping motion, etc. between the open position and the plugging position. The driving assembly 222 drives the plugging member 221 to move between the open position and the plugging position to conduct or cut off the main sewage pipe 212. The driving assembly 222 can be electrically connected to the control system. When no sewage discharge signal is received, the plugging member 221 is in the plugging position to cut off the main sewage pipe 212, so as to prevent external odors from entering the toilet body 10 through the main sewage pipe 212. When a sewage discharge signal is received, the driving assembly 222 drives the plugging member 221 to switch from the plugging position to the open position to conduct the main sewage pipe 212. At this time, the sewage in the sewage holding cavity 101 can be discharged through the main sewage pipe 212, so that automatic control of the plugging member 221 can be realized. In addition, when the driving assembly 222 fails or loses power, resulting in the plugging member 221 being unable to switch from the plugging position to the open position, the auxiliary sewage pipe 213 can also be used for sewage discharge to ensure that the sewage discharge function of the toilet is not affected.

[0077] In order to ensure the sealing performance in the non-sewage discharge state (such as the water seal state), in some embodiments, the switching mechanism 22 further includes a sealing member 224. The sealing member 224 is disposed on the plugging member 221 and / or the pipe body 21. When the plugging member 221 is in the plugging position, the sealing member 224 is used to sealingly connect the plugging member 221 and the pipe body 21. In this way, it can be ensured that in the non-sewage discharge state, the plugging member 221 cuts off the pipe body 21, and the mating part between the plugging member 221 and the pipe body 21 can be sealed by the sealing member 224, preventing the water in the sewage holding cavity 101 from seeping downward, and at the same time, it can also achieve a good odor isolation effect. Among them, the sealing member 224 can be disposed on the plugging member 221 to move together with the plugging member 221; or, the sealing member 224 can also be disposed on the pipe body 21 and remain fixed; or, sealing members 224 can be provided on both the plugging member 221 and the pipe body 21. The sealing member 224 includes but is not limited to using a sealing ring, a sealing sleeve or other structures capable of achieving sealing.

[0078] There are various ways for the driving assembly 222 to drive the plugging member 221 to move. For example, the plugging member 221 is slidably mounted on the pipe body 21, and the driving assembly 222 is used to drive the plugging member 221 to slide and switch between the open position and the plugging position; or, the plugging member 221 is rotatably mounted on the pipe body 21, and the driving assembly 222 is used to drive the plugging member 221 to rotate and switch between the open position and the plugging position. Several embodiments of the switching mechanism 22 are illustrated by way of example below.

[0079] As Figure 1 andFigure 2 As shown, in the first embodiment, the plugging member 221 is slidably mounted on the pipe body 21. The plugging member 221 has a plurality of tooth portions 2211 arranged along its sliding direction. The driving assembly 222 includes a first driving member 2221 and a gear 2222 drivingly connected to the first driving member 2221. The gear 2222 meshes with the tooth portions 2211 of the plugging member 221. The first driving member 2221 is configured to drive the gear 2222 to rotate, so as to drive the plugging member 221 to slide and switch between the open position and the plugging position.

[0080] In this embodiment, the plugging member 221 is slidably engaged with the pipe body 21. Optionally, the pipe body 21 is provided with a chute, and the plugging member 221 is slidably inserted into the chute. The plugging member 221 can be configured as a sliding plate extending along its sliding direction, and a plurality of tooth portions 2211 are provided on one side plate surface of the sliding plate along its sliding direction. The first driving member 2221 can be fixed to the pipe body 21 or the toilet body 10. The output end of the first driving member 2221 is connected with a gear 2222, and the gear 2222 meshes with the tooth portions 2211 of the plugging member 221. When the first driving member 2221 drives the gear 2222 to rotate, the plugging member 221 can be driven to perform a reciprocating linear motion between the plugging position and the open position. Among them, the plugging member 221 can be arranged at the inlet end of the main sewage pipe 212, or at other positions of the main sewage pipe 212. Optionally, the plugging member 221 is arranged at the inlet end of the main sewage pipe 212, that is, at a position of the main sewage pipe 212 close to the first diversion port. Among them, the first driving member 2221 includes but is not limited to power components capable of torque output such as a driving motor and a rotary cylinder. Of course, in some embodiments, the driving assembly 222 can also adopt electromagnetic driving, motor screw, pneumatic, hydraulic, etc. to realize the linear reciprocating motion of the plugging member 221. Optionally, the switching mechanism 22 further includes a sealing member 224 arranged on the plugging member 221. The sealing member 224 can slide along with the plugging member 221. When the plugging member 221 is in the plugging position, the sealing member 224 seals and connects the mating part of the plugging member 221 and the pipe body 21 to play a sealing role. Among them, the sealing member 224 includes but is not limited to a sealing sleeve sleeved on the plugging part of the plugging member 221, or a sealing ring sleeved on the outer periphery of the plugging member 221, or the sealing member 224 can also be integrally formed on the plugging member 221.

[0081] As Figure 6 and Figure 7As shown, in the second embodiment, the structures of the plugging member 221 and the driving assembly 222 are substantially the same as those of the plugging member 221 and the driving assembly 222 in the first embodiment. The main difference is that, in the second embodiment, the switching mechanism 22 further includes a sealing member 224 installed on the pipeline main body 21, and the sealing member 224 does not slide with the plugging member 221. When the plugging member 221 is in the plugging position, the sealing member 224 seals and connects the mating part of the plugging member 221 and the pipeline main body 21 to play a sealing role. Optionally, a bracket 225 for installing the sealing member 224 is provided in the pipeline main body 21 to ensure the installation stability of the sealing member 224. For the convenience of installing the sealing member 224 and the bracket 225, optionally, the pipeline main body 21 includes a first main body part 21a and a second main body part 21b that are spliced with each other. The bracket 225 is installed at the splicing part of the first main body part 21a and the second main body part 21b, and the sealing member 224 is sleeved on the outer periphery of the bracket 225.

The output end of the second driving member 2223 is connected to the rotating shaft 223 through the coupling 2224. The second driving member 2223 is used to drive the rotating shaft 223 to rotate, so as to drive the plugging member 221 to flip and switch between the open position and the plugging position.

[0083] In this embodiment, the plugging member 221 can be set as a movable plate adapted to the cross-sectional shape of the main sewage pipeline 212. The side edge of the plugging member 221 is connected to the rotating shaft 223 through a fixing part, and the rotating shaft 223 is rotatably connected to the pipeline main body 21. The output end of the second driving member 2223 is inserted and matched with one end of the coupling 2224, and the other end of the coupling 2224 is inserted and matched with the rotating shaft 223. By driving the coupling 2224 to rotate through the second driving member 2223, the rotating shaft 223 is driven to rotate through the coupling 2224, so as to drive the plugging member 221 to flip and switch between the plugging position and the open position. Among them, the second driving member 2223 includes but is not limited to power components such as driving motors and rotating cylinders that can achieve torque output. Of course, the driving assembly 222 can also drive the plugging member 221 to flip through linear pushing and pulling or other methods.

[0084] As Figure 10As shown, in the fourth embodiment, the plugging member 221 is rotatably connected to the pipeline main body 21 through a rotating shaft 223; the driving assembly 222 includes a third driving member 2225 and a pull rod 2226. One end of the pull rod 2226 is connected to the plugging member 221, and the other end of the pull rod 2226 is connected to the output end of the third driving member 2225. The third driving member 2225 is used to drive the pull rod 2226 to reciprocate axially, thereby driving the plugging member 221 to flip and switch between the open position and the plugging position around the rotating shaft 223.

[0085] In this embodiment, the plugging member 221 can be set as a movable plate adapted to the cross-sectional shape of the main sewage pipeline 212. The side edge of the plugging member 221 is connected to the rotating shaft 223 through a fixing part, and the rotating shaft 223 is rotatably connected to the pipeline main body 21. One end of the pull rod 2226 can be hinged to the plugging member 221, and the other end is connected to the output end of the third driving member 2225. By driving the pull rod 2226 to perform a linear reciprocating motion axially by the third driving member 2225, the plugging member 221 can be driven to flip around the rotating shaft 223 by the pull rod 2226. Among them, the third driving member 2225 includes but is not limited to using an electromagnet, a motor screw rod, a pneumatic, a hydraulic, etc. to realize the linear reciprocating motion of the pull rod 2226.

[0086] As Figures 11 to 14 As shown, in the fifth embodiment, the plugging member 221 is rotatably arranged in the pipeline main body 21. The plugging member 221 has a flow-through channel 2212. The driving assembly 222 is drivingly connected to the plugging member 221 to drive the plugging member 221 to rotate. When the plugging member 221 is in the open position, the flow-through channel 2212 is communicated with the main sewage pipeline 212. When the plugging member 221 is in the plugging position, the plugging member 221 cuts off the main sewage pipeline 212.

[0087] In this embodiment, the plugging member 221 can be the center of a sphere rotatably installed in the pipeline main body 21. The plugging member 221 has a flow-through channel 2212 penetrating through both axial ends thereof, and the driving assembly 222 drives the plugging member 221 to rotate. As Figure 13 As shown, when the plugging member 221 is in the open position, the extending direction of the flow-through channel 2212 is the same as the extending direction of the main sewage pipeline 212. At this time, the main sewage pipeline 212 is communicated, and the sewage in the sewage storage cavity 101 can enter the pipeline main body 21 and then enter the main sewage pipeline 212 through the flow-through channel 2212 and be discharged by the main sewage pipeline 212. As Figure 14As shown, when the plugging member 221 is in the plugging position, the extending direction of the flow-through channel 2212 intersects with the extending direction of the main sewage pipe 212. At this time, the main sewage pipe 212 can be plugged by the plugging member 221. Optionally, the plugging member 221 is provided with a connecting shaft. The driving assembly 222 includes a second driving member 2223 and a coupling 2224. The output end of the second driving member 2223 is connected to the connecting shaft of the plugging member 221 through the coupling 2224. By driving the coupling 2224 to rotate by the second driving member 2223, the plugging member 221 is driven to rotate. Among them, the second driving member 2223 includes, but is not limited to, power components such as driving motors and rotary cylinders that can achieve torque output. Optionally, the switching mechanism 22 further includes a sealing member 224 provided on the plugging member 221. The sealing member 224 can rotate with the plugging member 221. When the plugging member 221 is in the plugging position, the sealing member 224 seals the mating part of the plugging member 221 and the pipe body 21 to play a sealing role. Among them, the sealing member 224 includes, but is not limited to, a sealing sleeve, a sealing ring, etc. sleeved on the periphery of the plugging member 221, or the sealing member 224 can also be integrally formed on the plugging member 221.

[0088] As Figure 15 and Figure 16 As shown, in the sixth embodiment, the structures of the plugging member 221 and the driving assembly 222 are substantially the same as those of the plugging member 221 and the driving assembly 222 in the fifth embodiment. The main difference is that, in the sixth embodiment, the switching mechanism 22 further includes a sealing member 224 installed on the pipe body 21, and the sealing member 224 does not rotate with the plugging member 221. When the plugging member 221 is in the plugging position, the sealing member 224 seals the mating part of the plugging member 221 and the pipe body 21 to play a sealing role. Optionally, a bracket 225 for installing the sealing member 224 is provided in the pipe body 21 to ensure the installation stability of the sealing member 224. For the convenience of installing the plugging member 221 and the sealing member 224, optionally, the pipe body 21 includes a first main body part 21a and a second main body part 21b. The main sewage pipe 212 is provided in the first main body part 21a, and the sewage outlet 211 and the auxiliary sewage pipe 213 are provided in the second main body part 21b. The first main body part 21a and the second main body part 21b are spliced to form a spherical cavity, and the plugging member 221 is rotatably provided at the center of the spherical cavity.

[0089] In the above first to sixth embodiments, a siphon elbow 23 can be connected to the outlet end of the auxiliary sewage pipe 213, so that the auxiliary sewage pipe 213 is communicated with the lower sewage pipe 24 via the siphon elbow 23. When the sewage discharge device is in the auxiliary sewage discharge state, the siphon elbow 23 can be used to generate negative pressure to form a siphon, and the sewage can be discharged more cleanly, thereby further enhancing the effect of auxiliary sewage discharge and improving the sewage discharge capacity.

[0090] AsFigure 17 As shown, in the seventh embodiment, a siphon elbow 23 may not be provided at the outlet end of the auxiliary sewage pipe 213, so as to simplify the pipeline structure, save the installation space of the siphon elbow 23, and reduce the volume of the toilet.

[0091] The present utility model also proposes a toilet, which includes a toilet body 10 and a sewage discharge device of the toilet. The toilet body 10 has a sewage holding cavity 101, and the sewage discharge port 211 of the sewage discharge device of the toilet is communicated with the sewage holding cavity 101.
