[0058] In one embodiment, if Figure 1 and Figure 2 As shown, a toilet includes a main body 100, a connecting pipe 200, a sewage discharge assembly 300 and a driving assembly 400. Specifically, the material of the main body 100 can be ceramic. The main body 100 is placed on a floor 500.

[0059] In one embodiment, the main body 100 is provided with a pelvic cavity 110 and a water inlet 120 connected to the pelvic cavity 110. The water inlet 120 is connected to an external water pipe. When flushing is required, the external water pipe is turned on. External water enters the pelvic cavity 110 through the water inlet 120 to flush and clean the pelvic cavity 110. Specifically, the water inlet 120 is provided at the inner edge of the main body 100.

[0060] In one embodiment, please refer to Figure 7 The bottom of the pelvic cavity 110 is provided with a sewage inlet 130. One end of the connecting pipe 200 is communicated with the sewage inlet 130. One end of the connecting pipe 200 is communicated with the pelvic cavity 110. Dirt and water in the pelvic cavity 110 can enter the connecting pipe 200 through the sewage inlet 130. Specifically, one end of the connecting pipe 200 and the sewage inlet 130 can be detachably connected. That is, the connecting pipe 200 and the main body 100 can be a detachable structure.

[0061] In one embodiment, please refer to Figure 4 A sewage outlet 310 is disposed at one end of the sewage discharge assembly 300. The height of the sewage outlet 310 is lower than the height of the sewage inlet 130, so that the sewage and water in the sewage inlet 130 have gravitational potential energy.

[0062] The sewage outlet 310 is connected to the other end of the connecting pipe 200. Specifically, the other end of the connecting pipe 200 is detachably connected to the sewage outlet 310. That is, the connecting pipe 200 and the sewage discharge assembly 300 are detachable structures.

[0063] In the related art, the main body, S-bend pipe and sewage assembly of the siphon toilet are an integrated structure. During installation, the sewage assembly needs to be aligned with the external sewage channel, that is, the sewer. Since all three are an integrated structure. During the alignment process, the main body and the S-bend pipe also need to be moved synchronously. The main body is a very heavy ceramic structure, which makes the entire installation difficult. In this embodiment, the sewage assembly 300 can be aligned and connected with the external sewage channel alone, without the need to synchronously move the heavy main body 100 for alignment, and then move the main body 100 to the sewage assembly 300, and finally connect the main body 100 and the sewage assembly 300 through the connecting pipe 200, thereby reducing the difficulty of installation.

[0064] In one embodiment, the other end of the sewage discharge assembly 300 is used to communicate with an external sewage discharge channel. That is, the connecting pipe 200 is connected to the sewage inlet 130 and the sewage discharge port 310, so as to prevent external air from entering the connecting pipe 200 and enhance the siphon effect. The sewage in the connecting pipe 200 can enter the sewage discharge port 310 and the sewage discharge assembly 300 under the action of the siphon force, and be discharged to the external sewage discharge channel through the sewage discharge assembly 300.

[0065] In this embodiment, the connecting pipe 200 can move relative to the main body 100. The driving assembly 400 is drivingly connected to the connecting pipe 200, and can drive the highest position of the connecting pipe 200 to rise or fall relative to the main body 100, so that the connecting pipe 200 is respectively in an initial state, a water storage state and a sewage discharge state. When flushing, the driving assembly 400 drives the highest position of the connecting pipe 200 to rise. External water enters the pelvic cavity 110 through the water inlet 120, causing the water level in the pelvic cavity 110 to rise. When the water level in the pelvic cavity 110 reaches the preset water level, the driving assembly 400 drives the connecting pipe 200 to descend. The water and dirt in the pelvic cavity 110 enter the sewage discharge assembly 300 under the action of gravity and siphon force and are discharged to the external sewage discharge channel. By rising and falling the connecting pipe 200, the water and dirt in the basin 110 can be discharged to the sewage discharge assembly 300 under the action of gravity, thereby enhancing the sewage discharge effect. There is no need to set an additional nozzle at the bottom of the basin 110 to enhance the sewage discharge effect, thereby reducing the noise when the toilet is flushed and solving the problem of backflow after flushing.

[0066] Specifically, the connecting pipe 200 has a water storage state ( Figure 8 and Fig. 9 status shown) and sewage status ( Fig.10 and Fig.11The state shown). When the connecting pipe 200 is in the water storage state, the angle between the connecting pipe 200 and the horizontal plane is 90°, that is, the connecting pipe 200 is perpendicular to the horizontal plane. The highest point of the connecting pipe 200 is higher than the height of the sewage outlet 310, so that a water cover is formed in the pelvic cavity 110. When the connecting pipe 200 is in the sewage discharge state, the connecting pipe 200 has a downward tilt angle, and the height of the connecting pipe 200 is lower than the height of the sewage outlet 310, so that the water in the pelvic cavity 110 can enter the sewage discharge assembly 300 through the connecting pipe 200. The driving assembly 400 drives the connecting pipe 200 to rise or fall, so that the connecting pipe 200 switches between the water storage state and the sewage discharge state.

[0067] Please refer to Figure 6 and Figure 7 , the angle between the connecting pipe 200 and the horizontal plane is approximately 60°, and this position is the initial state of the connecting pipe 200. When flushing is needed, the driving component 400 drives the connecting pipe 200 to rise, increases the water level of the connecting pipe 200, and increases the water storage capacity of the pelvic cavity 110. This position is the water storage state of the connecting pipe 200. Turn on the external tap water pipe to flush water into the pelvic cavity 110. When the water level in the pelvic cavity 110 reaches a preset height, the driving component 400 drives the connecting pipe 200 to descend, and the connecting pipe 200 has a downward tilt angle. At this time, the connecting pipe 200 is in a sewage discharge state, so that the water and dirt in the pelvic cavity 110 enter the sewage outlet 310 under their own gravity.

[0068] In this embodiment, please refer to Figure 2 The connecting pipe 200 includes a first connecting pipe section 210, a second connecting pipe section 220, and a sewage pipe section 230 disposed between the first connecting pipe section 200 and the second connecting pipe section 220. The two ends of the first connecting pipe section 210 are respectively connected to one end of the sewage pipe section 230 and the sewage inlet 130. The two ends of the second connecting pipe section 220 are respectively connected to the other end of the sewage pipe section 230 and the sewage outlet 310. The driving assembly 400 is drivingly connected to the sewage pipe section 230, and the sewage pipe section 230 is movably arranged relative to the first connecting pipe section 210 and the second connecting pipe section 220. The sewage pipe section 230 can be a rigid pipe and a bending structure, and the first connecting pipe section 210 and the second connecting pipe section 220 can both be elastic flexible joints. The first connecting pipe section 210 and the pelvic cavity 110 can be fixedly connected at the sewage inlet 130, and the second connecting pipe section 220 and the sewage assembly 300 can be fixedly connected at the sewage outlet 310. The entire rigid pipe can move relative to the elastic flexible joint. The driving assembly 400 drives the entire rigid pipe to rise or fall. Specifically, the driving assembly 400 drives the sewage pipe section 230 to rise or fall.

[0069] Specifically, the toilet further includes a protective sleeve, which is sleeved on the outer periphery of the connecting pipe 200. The protective sleeve is specifically sleeved on the sewage pipe section 230. The driving assembly 400 is drivingly connected to the protective sleeve. By providing the protective sleeve, the degree of wear of the connecting pipe 200 during the rotation process can be reduced, and the service life of the connecting pipe 200 can be extended.

[0070] In another embodiment, the connecting pipe 200 may be a flexible pipe. In the related art, the ceramic structure of the S-bend pipe integrated with the toilet is relatively complicated to process, and glazing is required during the processing, which easily leads to uneven glazing and difficulty in inspection. The flexible pipe is not a ceramic structure and does not require a glazing process, which can reduce the processing cost.

[0071] In this embodiment, please refer to Figure 2 and Figure 3 , the driving assembly 400 includes a motor 410 and a rotating arm 420. The motor 410 is drivingly connected to the rotating arm 420. The rotating arm 420 is rotatably connected to the connecting pipe 200. The rotating arm 420 rotates up and down to drive the highest point of the connecting pipe 200 to rise and fall. Specifically, the rotating arm 420 is connected to the sewage pipe section 230, and the rotating arm 420 drives the sewage pipe section 230 to rotate relative to the main body 100. In another embodiment, the driving assembly 400 may also include a cylinder and a connecting rod. The cylinder is drivingly connected to the connecting rod. One end of the connecting rod away from the cylinder is connected to the connecting pipe 200. The connecting rod is driven by the cylinder to make a linear motion in the vertical direction, so that the connecting rod drives the connecting pipe to rise or fall. Specifically, the connecting rod can be but is not limited to a telescopic rod.

[0072] In one embodiment, the rotating arm 420 includes two connecting ends and a bending portion 424 provided at the two connecting ends. The bending portion 424 is bent toward one side of the connecting tube 200. Specifically, the bending portion 424 is bent toward the middle position of the connecting tube 200. In the design of an actual product, the rotating arm 424 cannot be directly designed at the middle position of the connecting tube 200. If the rotating arm 424 is set to a straight rod shape, the connection between the rotating arm 424 and the connecting tube 200 will be located at a position to the left or right of the connecting tube 200, resulting in an unbalanced force on the connecting tube 200 when the rotating arm 420 drives the connecting tube 200 to rise or fall. The bending portion 424 can make the connection between the rotating arm 420 and the connecting tube 200 deviate to the middle position of the connecting tube 200, so that the force on the connecting tube 200 is more balanced, and the connecting tube 200 can rise or fall stably.

[0073] like Figure 6 and Figure 7As shown, the connecting pipe 200 is in the initial state, that is, the toilet is not in use. The angle between the connecting pipe 200 and the horizontal plane is 60°. The motor 410 drives the rotating arm 420 to rotate 30° counterclockwise, and the rotating arm 420 drives the connecting pipe 200 to rotate 30° counterclockwise, so that the angle between the connecting pipe 200 and the horizontal plane is 90°. Fig. 9 That is, the rotating arm 420 drives the connecting pipe 200 to rise, so that the connecting pipe 200 is in a water storage state. The motor 410 drives the rotating arm 420 to rotate slightly more than 90 degrees in the clockwise direction, as shown in FIG. Fig.11 As shown, the connecting pipe 200 has a downward tilt angle. That is, the rotating arm 420 drives the connecting pipe 200 to descend, so that the connecting pipe 200 is in a sewage discharge state. The clockwise direction and the counterclockwise direction in this article are both Figure 7 , Fig. 9 and Fig.11 For reference.

[0074] In one embodiment, please refer to Figure 3 The toilet further includes a base 600. A rotating shaft 430 is rotatably provided on the base 600. Specifically, a first support seat 610 and a second support seat 620 are provided on the base 600. The first support seat 610 and the second support seat 620 are arranged opposite to each other. The rotating shaft 430 is rotatably provided between the first support seat 610 and the second support seat 620. More specifically, the first support seat 610 is provided with a first through hole. The second support seat 620 is provided with a second through hole opposite to the first through hole. The rotating shaft 430 is rotatably provided in the first through hole and the second through hole.

[0075] In one embodiment, the motor 410 is disposed on the base 600. The motor 410 is fixedly disposed on the base 600. The base 600 can support the motor 410. The motor 410 is drivingly connected to the rotating shaft 430. Specifically, the output shaft at the end of the motor 410 is drivingly connected to the rotating shaft 430. One end of the rotating arm 420 is connected to the rotating shaft 430, and the other end is connected to the connecting pipe 200.

[0076] In this embodiment, please refer to Figure 3 , a protrusion 630 is provided on the base 600. The protrusion 630 is provided between the first support seat 610 and the second support seat 620. The protrusion 630 is located directly below the rotation shaft 430. Specifically, the protrusion 630 can be a plate-shaped structure or a block-shaped structure.

[0077] In one embodiment, please refer to Figure 5 , a first limiting portion 421 is provided at one end of the rotating arm 420 close to the base 600. The first limiting portion 421 may be a protrusion extending along the length direction of the rotating arm 420. Figure 5As shown in the angle, the first limiting portion 421 is disposed at a position to the right of the central axis of the rotating arm 420. When the rotating arm 420 rotates clockwise to be perpendicular to the horizontal plane, the first limiting portion 421 abuts against the protrusion 630 to limit the rotating arm 420 from continuing to rotate clockwise, thereby limiting the rotation range of the rotating arm 420. Through the cooperation between the first limiting portion 421 and the protrusion 630, the rotation of the rotating arm 420 in the clockwise direction can be limited, thereby limiting the rotation of the connecting pipe 200 in the clockwise direction.

[0078] In one embodiment, please refer to Figure 5 , a second limiting portion 422 is further provided at one end of the rotating arm 420 close to the base 600. The second limiting portion 422 is provided on the side of the rotating arm 420 away from the sewage inlet 130. That is, the second limiting portion 422 is a protrusion extending along the width direction of the rotating arm 420. When the rotating arm 420 rotates counterclockwise until the connecting pipe 200 tilts downward, the second limiting portion 422 can abut against the protrusion 630 to limit the rotating arm 420 to limit the rotation range of the rotating arm 420. Through the cooperation of the second limiting portion 422 and the protrusion 630, the rotation of the rotating arm 420 in the counterclockwise direction can be limited, thereby limiting the rotation of the connecting pipe 200 in the counterclockwise direction.

[0079] Through the cooperation of the first limiting part 421 and the second limiting part 422, the connecting pipe 200 can be rotated at a preset angle, thereby controlling the rising and falling height of the connecting pipe 200, ensuring that the water level of the pelvic cavity 110 can be at a preset height when the connecting pipe 200 is in the water storage state. At the same time, it is ensured that the connecting pipe 200 has a downward tilt angle when the connecting pipe 200 is in the sewage discharge state, and the sewage and water in the sewage outlet 310 can flow into the sewage outlet 310 under the action of gravity.

[0080] In one embodiment, a clamping portion 423 is provided at one end of the rotating arm 420 away from the base 600, and the clamping portion 423 can clamp the connecting pipe 200. The clamping portion 423 can be a clamping groove, and the connecting pipe 200 is clamped in the clamping groove. The clamping portion 423 can also be a circular structure to adapt to the shape of the connecting pipe 200.

[0081] In this embodiment, the toilet also includes a flow meter 700 and a solenoid valve 710. The flow meter 700 is connected to the solenoid valve 710, and the flow meter 700 is used to measure the amount of water entering the pelvic cavity 110. The solenoid valve 710 is respectively connected to the water inlet 120 and the external water source. The flow meter 700 is electrically connected to the solenoid valve 710 and the drive assembly 400. When the connecting pipe 200 moves from the initial state to the water storage state, when the pelvic cavity 110 is filled with water, the flow meter 700 is used to measure the amount of water storage. When the water storage reaches a preset value, the solenoid valve 710 is closed, and the drive assembly 400 drives the connecting pipe 200 to rotate and switch to the sewage discharge state.

[0082] In one embodiment, the toilet further includes an angle sensor 720. The angle sensor 720 is electrically connected to the drive assembly 400. The angle sensor 720 is used to sense the angle information of the connection pipe 200 rotation. When the angle information reaches the first angle, the second angle and the third angle, the drive assembly 400 stops driving the connection pipe 200 to rotate. For example, the first angle may be 60°. The second angle may be 90°. The third angle may be 0°. Specifically, the angle sensor 720 is used to sense the rotation angle of the drive shaft of the drive assembly 400 and obtain the angle information of the drive shaft.

[0083] Specifically, the angle sensor 720 may be a Hall angle sensor. The motor 410 and the rotating shaft 430 may be driven by the worm 730 and the gear assembly 740. The output shaft of the motor 410 is connected to the worm 730. The worm 730 is meshed with the gear assembly 740. The rotating shaft 430 is connected to the gear assembly 740. The motor 410 drives the worm 730 to rotate, the worm 730 drives the gear assembly 740 to rotate, and the gear assembly 740 drives the rotating shaft 430 to rotate. The worm 730 and the gear assembly 740 also have a self-locking function. When the connecting tube 200 is in the initial state, the connecting tube 200 is at the first angle, and the worm 730 and the gear assembly 740 lock the connecting tube 200 to prevent the connecting tube 200 from falling due to its own weight. A magnet 750 is fixedly arranged inside the rotating shaft 430. The magnet 750 rotates synchronously with the rotating shaft 430. The Hall angle sensor is disposed close to the magnet 750 , and can detect the rotation angle of the magnet 750 , thereby detecting the rotation angle of the rotating shaft 430 .

[0084] In one embodiment, the toilet further includes a controller, which is electrically connected to the drive assembly 400 and is used to identify a large flush signal and a small flush signal. For example, a user long presses the flush button to trigger a large flush signal. A user short presses the flush button to trigger a small flush signal.

[0085] When the controller obtains the big rush signal, the driving component 400 drives the connecting pipe 200 to switch from the initial state to the water storage state. The driving component 400 drives the connecting pipe 200 to switch from the water storage state to the sewage discharge state. After the sewage discharge is completed, the driving component 400 drives the connecting pipe 200 to switch from the sewage discharge state to the initial state.

[0086] When the controller obtains the small flush signal, the driving component 400 drives the connecting pipe 200 to switch from the initial state to the sewage discharge state. After the sewage discharge is completed, the driving component 400 drives the connecting pipe 200 to switch from the sewage discharge state to the initial state. The user can control the amount of water used by large flushing and small flushing.
