Description

Technical Field

[0001] This specification relates to the field of toilets, particularly but not limited to toilet devices.

Background Art

[0002] In current toilet devices, some toilets apply a waste discharge structure with a reversible waste discharge pipe. The reversible waste discharge pipe has a horizontal ceramic waste discharge pipe and an L-shaped bend pipe abutted to the waste discharge pipe.

[0003] The toilet seat body is mainly made of ceramics, and there are cases where the seal with the waste discharge box (the L-shaped bend pipe is attached to the waste discharge box) is not strict. The method of using an adhesive for bonding can solve the sealing problem to a certain extent, but there are also problems with the angle in the adhesive bonding method itself. For example, it cannot be disassembled and assembled conveniently, and it is inconvenient to replace the adhesive even when it ages. Also, even if bolts or the like are used as connecting parts for connection, the number of connecting parts that can be installed is limited, so there are problems such as uneven stress in the connection area between the toilet seat body and the waste discharge box.

[0008] The embodiments of the present application will now be described. Examples of the embodiments are shown in the drawings, and the same or similar reference numerals from beginning to end indicate the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are for illustrative purposes only, and should not be construed as limiting the embodiments of the present application.

[0009] Current toilets with L-shaped waste discharge pipes have a major problem with the seal between the waste discharge box and the toilet seat. Specifically, although the surface of the ceramic material is visually flat, it is not yet flat for sealing water and gas. On the other hand, toilet seats are generally made of ceramic material, and it is inconvenient to create holes, screws, grooves, etc. in ceramic material, making it difficult to connect the toilet seat and the waste discharge box, resulting in a poor connection.

[0010] Currently, the most common method is direct adhesive bonding, where a large amount of adhesive is applied to the joint between the waste disposal box and the toilet seat, with the adhesive acting as both a seal and a bond. However, this adhesive connection method still has significant problems. Specifically, it is difficult to connect and disconnect the adhesive, making repairs and replacements difficult. Furthermore, after long-term use, the adhesive tends to deteriorate and become ineffective, increasing the risk of water leakage.

[0011] Embodiments of the present invention provide a toilet device comprising a toilet seat and a waste discharge mechanism, wherein the toilet seat is provided with a toilet bowl and a waste discharge port communicating with the toilet bowl, a waste discharge connection part is provided on the outer circumference of the waste discharge port, the waste discharge connection part is located outside the toilet bowl and has a passage communicating with the waste discharge port, the waste discharge mechanism comprises a waste discharge box, the waste discharge box is provided with a waste intake port communicating with the passage, a waste intake connection part is provided on the outer circumference of the waste intake port, the waste intake connection part protrudes from the outer wall of the waste discharge box, the waste intake connection part and the waste discharge connection part are detachably connected to fix the waste discharge box to the toilet seat.

[0012] The seal connection structure in the toilet device according to the embodiment of the present invention is reliable in use and easy to remove for repair, replacement, etc. The work on the seal connection part is highly reliable and resistant to damage. Parts that may wear out (e.g., snap-fit ​​connection parts) can be replaced by removing the toilet device, making it highly practical and extending the service life of the toilet device.

[0013] The embodiment of the present invention provides a toilet device, as shown in Figures 1 to 16. The toilet device comprises a toilet seat body 1, a waste discharge mechanism 2, and a snap-fit ​​connecting part 3. The toilet seat body 1 is provided with a toilet bowl 11 and a waste discharge port 12 communicating with the toilet bowl 11. A waste discharge connection part 13 is provided on the outer circumference of the waste discharge port 12. The waste discharge connection part 13 is located outside the toilet bowl 11 and has a passage that communicates with the waste discharge port 12. The waste discharge mechanism 2 comprises a waste discharge box 21. The waste discharge box 21 is provided with a waste intake port 211 that communicates with the passage. A waste intake connection part 23 is provided on the outer circumference of the waste intake port 211. The waste intake connection part 23 protrudes from the outer wall of the waste discharge box 21 and is fixedly connected to the waste discharge connection part 13 via the snap-fit ​​connecting part 3, thereby fixedly connecting the toilet seat body 1 and the waste discharge box 21.

[0014] The waste discharge mechanism 2 may include a waste discharge pipe 22 located inside the waste discharge box 21, which communicates with the waste intake port 211 and can rotate relative to the waste discharge box 21 to discharge waste. The waste discharge pipe 22 and the waste discharge box 21 may be made of plastic, and the toilet seat body 1 may be made of ceramic.

[0015] To enhance the connection effect, multiple snap-fit ​​connecting parts 3 may be provided circumferentially around the waste discharge box 21, ensuring uniform load distribution between the toilet seat body 1 and the waste discharge box 21, and preventing distortion and easy detachment after connection.

[0016] In the toilet device according to the embodiment of the present invention, the toilet seat body 1 and the waste discharge box 21 are fixedly connected with a snap-fit ​​connecting part 3. The snap-fit ​​connecting part 3 is securely fixed, the connection effect is good, the end faces of the waste discharge connection part 13 and the waste suction connection part 23 are more tightly in contact, and a large gap is avoided at the connection point between the toilet seat body 1 and the waste discharge box 21, thereby avoiding water leakage and odor problems.

[0017] In actual operation, the waste suction connection part 23 may be made of plastic, and after a certain pressing force is applied to the snap-fit ​​connection part 3, a small deformation occurs in the waste suction connection part 23, which can make the waste discharge connection part 13 fit more tightly and improve the sealing performance.

[0018] A waste suction connection part 23 is installed at the waste suction port 211 of the waste discharge box 21, and a waste discharge connection part 13 is installed at the waste discharge port 12 of the toilet seat body 1. The installation of the waste suction connection part 23 and the waste discharge connection part 13 facilitates connection. By fixing the waste suction connection part 23 and the waste discharge connection part 13, connection of the toilet seat body 1 to the waste discharge box 21 is achieved, simplifying the connection structure and avoiding the need to drill holes or other methods to connect the main body structures of the toilet seat body 1 and the waste discharge box 21, making it efficient and practical.

[0019] In one exemplary embodiment, as shown in Figures 2 to 5, the snap-fit ​​connector 3 includes a first connector 31, the first connector 31 includes at least one snap component 311 that engages with a snap projection 321. One of the first connector 31 and the snap projection 321 is provided on the waste discharge connector 13, and the other is provided on the waste suction connector 23. The snap component 311 is hooked onto the snap projection 321 and engages with the snap projection 321, and is configured to restrict the waste suction connector 23 from detaching from the waste discharge connector 13.

[0020] The snap component 311 may also function as a main buckle, and the snap projection 321 may also function as a sub-buckle. The snap-fit ​​connecting component 3 is buckled together by the buckle engagement between the sub-buckle and the main buckle.

[0021] The first connecting part 31 may be provided on the waste suction connection part 23, and the snap projection 321 may be provided on the waste discharge connection part 13. The snap part 311 and the snap projection 321 are connected by a hooking method, thereby restricting and fixing the waste suction connection part 23 to the waste discharge connection part 13.

[0022] Of course, the first connecting part 31 may be provided on the waste discharge connecting part 13, and the snap projection 321 may be provided on the waste suction connecting part 23.

[0023] In one exemplary embodiment, as shown in Figures 4 and 5, the first connecting component 31 further includes a retaining ring 312, which is fitted to the outside of the waste suction connection 23 or the waste discharge connection 13, and the snap component 311 and the retaining ring 312 are movably connected.

[0024] The snap component 311 is fitted to the outside of the waste suction connection 23 via a fixing ring 312. The fixing ring 312 acts as an intermediate mounting component, simplifying the structure of the snap component 311 and enabling attachment of the snap component 311 to the waste suction connection 23. It is also movable (for example, rotated) relative to the waste suction connection 23 so as to hook onto and detach from the snap projection 321.

[0025] Of course, the snap component 311 may be installed on the outside of the waste discharge connection part 13.

[0026] In one exemplary embodiment, as shown in Figures 4 and 5, the first connecting component 31 further includes a locking component 313, which is configured to lock the snap component 311 in a position to align with the snap projection 321.

[0027] The first connecting part 31 further includes a locking part 313, which engages with the snap part 311. After the snap part 311 and the snap projection 321 engage, the locking part 313 restricts and fixes the snap part 311, preventing the snap part 311 from automatically rotating and detaching.

[0028] In one exemplary embodiment, as shown in Figures 4 and 5, the snap component 311 is rotatably connected to the retaining ring 312, and the locking component 313 is rotatably connected to the retaining ring 312. After the snap component 311 rotates along a first direction to align with the snap projection 321, the locking component 313 rotates along a second direction opposite to the first direction to a locked position, and the resistance force increases and then decreases during the rotation to the locked position. The direction in which the snap component 311 or the locking component 313 moves toward the waste discharge connection 13 is the first direction, shown in direction A in Figure 4. The direction in which the snap component 311 or the locking component 313 rotates toward the waste discharge connection 13 is the second direction, shown in direction B in Figure 4.

[0029] The locking component 313 is rotatably connected to the fixing ring 312. After rotating the snap component 311 to hook onto the snap projection 321 and connect it, the locking component 313 is rotated in the opposite direction to lock it in place.

[0030] The locking part 313 increases and then decreases resistance during the rotation process to the locking position. In other words, since the locking part 313 cannot detach on its own after reaching the locking position, it ensures the locking and limiting effect of the locking part 313, secures the connection between the toilet seat body 1 and the waste discharge box 21, and improves the operational reliability of the toilet device. When it is necessary to release the locking of the locking part 313, the operator rotates the locking part 313 to the unlocked position against the resistance force during rotation of the locking part 313. In other words, the locking part 313 becomes self-locking after rotating to the locking position. Locking part 313 Due to the changing resistance force during rotation, and due to factors such as external forces and impacts Locking part 313 This can prevent them from unintentionally leaving.

[0031] In one exemplary embodiment, as shown in Figures 4 and 5, a mounting seat 3121 is provided on the fixing ring 312, and both the snap component 311 and the locking component 313 are pivotally connected to the mounting seat 3121, and the pivot axes of the snap component 311 and the locking component 313 are offset from each other, with the pivot axis of the snap component 311 further inserted into the locking component 313.

[0032] A mounting seat 3121 is installed on the fixing ring 312, the locking part 313 is rotatably attached to the mounting seat 3121, and the snap part 311 is rotatably attached to the mounting seat 3121, and the rotation axes of the snap part 311 and the locking part 313 are set parallel and separated by a certain distance.

[0033] After the snap component 311 is hooked onto the snap projection 321 and connected, the locking component 313 rotates in the reverse direction to securely hook and lock the snap component 311 onto the snap projection 321, preventing the buckle connection from automatically detaching. Regarding the locking of the locking component 313, the resistance force increases and then decreases during the process of the locking component 313 rotating to the locking position. In other words, to release the locking of the locking component 313, it is necessary to overcome the resistance force during the rotation process of the locking component 313 and rotate the locking component 313 to the unlocked position. In other words, the locking component 313 self-locks after rotating to the locking position. During the rotation process of the locking part 313 It cannot overcome the significant resistance and release itself, requiring an operator to apply external force to release the lock and open it.

[0034] In one exemplary embodiment, the waste discharge connection 13 or the waste suction connection 23 is provided with a first annular flange 232 to restrict the axial detachment of the fixing ring 312.

[0035] As shown in Figure 13, a first annular flange 232 is provided at the end of the waste suction connection portion 23, and the first annular flange 232 restricts the fixing ring 312, preventing it from detaching along the axial direction.

[0036] Furthermore, in order for the waste discharge connection portion 13 to be sealed, the first annular flange 232 may be provided with a groove for attaching the sealing component 4 (i.e., the first mounting groove or the second mounting groove described later).

[0037] In one exemplary embodiment, as shown in Figures 2, 3 and 7, the snap-fit ​​connector 3 further includes a second connector 32, one of which is provided on the waste discharge connector 13 and the other on the waste suction connector 23, and the snap projection 321 is provided on the second connector 32.

[0038] The second connecting part 32 can be installed in the waste discharge connecting part 13, the first connecting part 31 can be installed in the waste suction connecting part 23, and the snap projection 321 is installed in the second connecting part 32 and is located in the waste discharge connecting part 13.

[0039] In one exemplary embodiment, as shown in Figure 7, the second connecting component 32 includes a retaining ring 322 which is fitted to the outside of the waste discharge connection 13 or the waste suction connection 23, and a snap projection 321 is installed on the retaining ring 322 and protrudes outward along the radial direction of the retaining ring 322.

[0040] The snap projection 321 is installed on the waste discharge connection part 13 via the retaining ring 322, and the retaining ring 322 serves as an intermediate mounting structure. The snap projection 321 is mainly Snap part 311 It is sufficient for the retaining ring 322 to serve as a superimposing element, and by having the retaining ring 322 function to connect with the waste discharge connection part 13, the structure of the snap projection 321 can be simplified, the strength of the snap projection 321 can be improved, and the connection stability between the snap component 311 and the snap projection 321 can be further improved.

[0041] The snap projection 321 is provided on the second connecting component 32, and the snap projection 321 protrudes radially from the second connecting component 32, contributing to the hook connection of the snap component 311.

[0042] In one exemplary embodiment, as shown in Figure 7, the retaining ring 322 is locally bent to form a snap projection 321, and a connecting portion 323 is provided on the portion of the retaining ring 322 radially opposite the snap projection 321, and the connecting portion 323 is removably connected to the first connecting component 31.

[0043] The retaining ring 322 is bent radially in a convex shape to form a snap projection 321. In other words, the retaining ring 322 and the snap projection 321 are an integrated structure, improving the connection strength between them and reducing manufacturing costs.

[0044] A connecting portion 323 is provided on the portion of the retaining ring 322 that is radially opposite to the snap projection 321, and the connecting portion 323 is detachably connected to the first connecting component 31, for example, by a hinge connection. Due to the structure of the two locations, the connecting portion 323 and the snap projection 321, there are at least two connections between the first connecting component 31 and the second connecting component 32, which prevents distortion from occurring in both during connection and ensures the stability of the connection between them.

[0045] As should be understood, instead of providing a connecting portion 323 at the radially opposing portions of the retaining ring 322 and the snap projection 321, other snap projections may be provided. In other words, as shown in Figure 6, the retaining ring 322 is provided with two snap projections 321, and correspondingly, the fixing ring 312 is provided with two snap components 311.

[0046] In one exemplary embodiment, as shown in Figure 7, the retaining ring 322 is elongated and bent to form an annular shape with an opening. The front and end ends of the retaining ring 322 in the opening extend toward the retaining ring 312 to form a connecting portion 323. The connecting portion 323 includes a first radial portion 3231, a first axial portion 3232, and a first circumferential portion 3233 located at the front of the retaining ring 322 and connected sequentially, and a second radial portion 3234, a second axial portion 3235, and a second circumferential portion 3236 located at the end of the retaining ring 322 and connected sequentially. The first radial portion 3231 and the second radial portion 3234 are installed parallel to each other, the first axial portion 3232 and the second axial portion 3235 are installed parallel to each other, and the first circumferential portion 3233 and the second circumferential portion 3236 are installed facing each other or back to back. The first connecting component 31 is provided with a mounting plate 314 that extends radially, and a mounting hole 3141 is provided in the mounting plate 314. Two mounting plates 314 are provided side by side in the circumferential direction of the first connecting component 31, and the first circumferential portion 3233 and the second circumferential portion 3236 extend into the mounting hole 3141 of one of the mounting plates 314, respectively.

[0047] Both the front and end ends of the retaining ring 322 extend toward the fixing ring 312, contributing to the connection of the fixing ring 312. The connecting portions 323 formed at both the front and end ends of the retaining ring 322 are removably connected to the mounting plate 314 on the fixing ring 312.

[0048] The first radial portion 3231 extends radially to avoid interference when the retaining ring 322 extends toward the fixing ring 312. The first axial portion 3232 extends toward the fixing ring 312. The first circumferential portion 3233 is located on the mounting plate 314 of the fixing ring 312 and is inserted into the mounting hole 3141 to achieve a plug connection. The second radial portion 3234, the second axial portion 3235, and the second circumferential portion 3236 are similar.

[0049] In one exemplary embodiment, the waste discharge connection 13 or the waste suction connection 23 is provided with a second annular flange 132 to restrict the axial detachment of the retaining ring 322.

[0050] The retaining ring 322 is attached to the waste discharge connection part 13, and the waste discharge connection part 13 is provided with a second annular flange 132 that protrudes radially, as shown in Figure 8, the second annular flange 132 is for preventing the retaining ring 322 from detaching from the waste discharge connection part 13.

[0051] Furthermore, in order for the waste suction connection portion 23 to be sealed, the second annular flange 132 may be provided with a groove for attaching the sealing component 4 (i.e., the first mounting groove or the second mounting groove described later).

[0052] In one exemplary embodiment, the axial end face of the second annular flange 132 away from the sewage suction connection portion 23 abuts against the retaining ring 322, or the second annular flange 132 is provided with an annular limiting groove 1321, and the retaining ring 322 is fitted into the annular limiting groove 1321.

[0053] The waste discharge connection section 13 includes a waste discharge pipe section 131 that extends axially, and a second annular flange 132 installed on the outer wall at the end of the waste discharge pipe section 131. The retaining ring 322 is fitted onto the waste discharge pipe section 131 of the waste discharge connection section 13 and is restrained by contact with the second annular flange 132, preventing the retaining ring 322 from detaching from the waste discharge pipe section 131.

[0054] The retaining ring 322 may not be installed on the waste discharge pipe section 131, but rather fitted onto the second annular flange 132. An annular limiting groove 1321 is installed on the second annular flange 132, and the retaining ring 322 is attached to the limiting groove 1321. The limiting groove 1321 may be a groove with a U-shaped cross-section, or an L-shaped stepped groove.

[0055] Of course, when the second annular flange 132 is provided on the sewage suction connection part 23, the retaining ring 322 is fitted to the sewage suction pipe part 231 or the second annular flange 132 of the sewage suction connection part 23 accordingly.

[0056] In one exemplary embodiment, as shown in Figure 10, the snap projection 321 and the waste suction connection 23 or waste discharge connection 13 are integrated into a single structure. There are multiple snap projections 321, and the multiple snap projections 321 are uniformly arranged along the circumferential direction of the waste suction connection 23 or waste discharge connection 13.

[0057] The waste discharge connection portion 13 may have snap protrusions 321 that protrude radially, and multiple snap protrusions 321 may be installed uniformly distributed along the circumferential direction.

[0058] By integrating the snap projection 321 and the waste discharge connection part 13 into a single structure, the connection strength of the snap projection 321 can be improved, simplifying the assembly process. Furthermore, there is no need to fit a retaining ring 322 or other structure onto the waste discharge connection part 13, thereby improving the installation efficiency of the toilet device.

[0059] Of course, the snap projection 321 may also be installed on the waste suction connection part 23.

[0060] In one exemplary embodiment, as shown in Figure 7, the snap projection 321 includes an extending portion 3211 and a restricting portion 3212 that extend radially along the waste discharge connection portion 13, with one end of the restricting portion 3212 connected to the extending portion 3211 and the other end of the restricting portion 3212 extending at an angle away from the snap component 311.

[0061] The extended portion 3211 of the snap projection 321 extends radially, and the snap component 311 contacts and hooks onto the extended portion 3211. A limiting portion 3212 is provided at the end of the extended portion 3211, which prevents the snap component 311 from detaching from the snap projection 321 and improves the reliability of the connection.

[0062] The limiting portion 3212 may take on multiple forms. For example, the limiting portion 3212 may be a limiting projection that prevents the snap component 311 from detaching along the radial direction. Alternatively, the limiting portion 3212 may be formed by bending the end of the extended portion 3211, and its inclined surface may be used to increase the resistance force when the snap component 311 detaches.

[0063] In one exemplary embodiment, as shown in Figure 7, an obtuse angle is formed between the extending portion 3211 and the limiting portion 3212, and the angle of the obtuse angle is in the range of 120° to 175°.

[0064] An obtuse angle is formed between the extended portion 3211 and the limiting portion 3212. In other words, the inclined surface (obtuse angle) is used to increase the resistance force when the snap part 311 detaches. The angle of the obtuse angle is in the range of 120° to 175°, and may be, for example, 120°, 135°, or 175°, ensuring an anti-detachment effect.

[0065] In one exemplary embodiment, the waste discharge connection section 13 includes a waste discharge pipe section 131 and a second annular flange 132 provided on the outer wall of the waste discharge pipe section 131, and the waste suction connection section 23 includes a waste suction pipe section 231 and a first annular flange 232 provided on the outer wall of the waste suction pipe section 231. The waste suction pipe section 231 and the waste discharge pipe section 131 are in communication with abutment, the first annular flange 232 and the second annular flange 132 are in contact along the axial direction, and the snap-fit ​​connector 3 securely connects the toilet seat body 1 and the waste discharge box 21 by locking the first annular flange 232 and the second annular flange 132.

[0066] The first connecting component 31 may be attached to the waste suction pipe section 231 and restricted by the first annular flange 232, and the second connecting component 32 may be attached to the waste discharge pipe section 131 and restricted by the second annular flange 132. By buckling the first connecting component 31 and the second connecting component 32 together, the first annular flange 232 and the second annular flange 132 are locked together, thereby fixing the toilet seat body 1 and the waste discharge box 21 together.

[0067] In one exemplary embodiment, the toilet system further includes a rotation prevention structure for restricting the rotation of the waste discharge box 21 relative to the toilet seat body 1.

[0068] A rotation prevention structure is installed between the waste suction connection part 23 and the waste discharge connection part 13 to prevent the waste discharge box 21 from rotating.

[0069] The snap-fit ​​connector 3 connects and fixes the waste discharge connector 13 and the waste suction connector 23, restricting their axial movement and preventing the waste discharge box 21 from detaching rearward along the axial direction relative to the toilet seat body 1. When the waste discharge box 21 is subjected to a circumferential force, the snap-fit ​​connector 3 has a certain circumferential restricting effect. By providing a rotation prevention structure between the waste suction connector 23 and the waste discharge connector 13, it is possible to prevent the waste discharge box 21 from rotating relative to the toilet seat body 1 due to circumferential forces, thereby completely fixing and restricting the waste discharge box 21 and further enhancing the circumferential restricting effect between the toilet seat body 1 and the waste discharge box 21, thus preventing the waste discharge box 21 from moving or rotating during operation and ensuring reliable operation of the toilet device.

[0070] In one exemplary embodiment, as shown in Figures 9 and 13, a protrusion 133 is provided on one of the waste discharge connection portion 13 and the waste suction connection portion 23, and a receiving groove 233 is provided on the other, and the rotation prevention structure includes the protrusion 133 and the receiving groove 233. Alternatively, a first restricting hole is provided in the waste discharge connection portion 13 and a second restricting hole is provided in the waste suction connection portion 23 (not shown). The rotation prevention structure includes a restricting component, which is drilled in the first and second restricting holes along the axial direction of the waste suction connection portion 23, and restricts the rotation of the waste suction connection portion 23 relative to the waste discharge connection portion 13.

[0071] The anti-rotation structure may have multiple forms. For example, a protrusion 133 may be provided on the waste suction connection part 23. , at the waste discharge connection part 13 A receiving groove 233 is provided, and the protrusion 133 engages with the receiving groove 233 to restrict the relative rotation between the waste discharge mechanism 2 and the toilet seat body 1.

[0072] Alternatively, the limiting component is passed through the first limiting hole of the waste discharge connection part 13 and the second connection hole of the waste suction connection part 23 along the axial direction to restrict the relative rotation between the waste discharge mechanism 2 and the toilet seat body 1.

[0073] In one exemplary embodiment, a first mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a first sealing component is provided in the first mounting groove, and the first sealing component abuts against the axial end face of the waste suction connection portion 23 and the axial end face of the waste discharge connection portion 13 to form an end face seal. and / or, a second mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a second sealing component is provided in the second mounting groove, and the second sealing component abuts against the radial inner end of the waste suction connection portion 23 and the radial outer end of the waste discharge connection portion 13 to form a radial seal.

[0074] As shown in Figure 12, the toilet system further includes a sealing component 4 provided between the waste suction connection part 23 and the waste discharge connection part 13.

[0075] By interposing a sealing component 4 between the waste suction connection 23 and the waste discharge connection 13, and combining this with the clamping force provided by the snap-fit ​​connection component 3, the sealing performance between the waste suction connection 23 and the waste discharge connection 13 can be further improved, ensuring that phenomena such as water leakage and odor do not occur at the connection point between the two.

[0076] The sealing component 4 can perform the role of a static seal and may be, for example, a rubber sealing component.

[0077] The sealing configuration of the sealing component 4 may be an end face seal, a radial seal, or a configuration having both an end face seal and a radial seal.

[0078] For the end face seal, a first mounting groove is installed in the waste suction connection part 23, the seal component 4 is mounted in the first mounting groove along the axial direction, and the waste discharge connection part 13 abuts against the seal component 4 in the first mounting groove. After connecting the waste suction connection part 23 and the waste discharge connection part 13, the snap-fit ​​connecting component 3 can exert a certain pressing effect on the seal component 4. In other words, the snap-fit ​​connecting component 3 can compress the seal component 4, thereby enhancing the sealing effect of the seal component 4.

[0079] Regarding the radial seal, a second mounting groove is installed in the waste suction connection part 23, and the seal part 4 is positioned radially. in the second mounting groove The waste discharge connection portion 13 is attached to the second mounting groove, and the waste discharge connection portion 13 abuts against the seal component 4. In the radial direction, the space between the waste suction connection portion 23 and the waste discharge connection portion 13 may be a gap fit, and the seal component 4 can be fitted into the second mounting groove by interlocking. In other words, the seal component 4 is compressed by pressing it against the inner wall of the waste suction connection portion 23 and the outer wall of the waste discharge connection portion 13, thereby enhancing the sealing effect of the seal component 4.

[0080] The toilet device according to the embodiment of the present invention achieves a simple and reliable connection between the toilet seat body 1 and the waste discharge mechanism 2 by using a buckle connection method between a child buckle and a parent buckle. In actual operation, locking and unlocking can be achieved by rotating the locking part of the first connecting part 31, making attachment and detachment convenient, as well as repair and removal.

[0081] By placing the sealing component 4 between the toilet seat body 1 and the waste discharge box 21, and fastening and fixing the waste discharge box 21 and the toilet seat body 1 via the snap-fit ​​connecting component 3, the compression amount of the sealing component 4 is kept large, reducing sealing defects caused by large variations in the ceramic dimensions of the toilet seat body 1.

[0082] The toilet system may also be equipped with a shifter 51, which is located below the waste discharge mechanism 2, with the inlet of the shifter 51 communicating with the outlet of the waste discharge box 21, and the outlet of the shifter 51 communicating with the external waste discharge piping. A rim spout 52 is attached to the toilet seat body 1, and the rim spout 52 is fixed to the toilet seat body 1 to draw water for flushing the toilet system.

[0083] Furthermore, the waste discharge pipe 22 forms a dynamic seal with an oil seal and a waste discharge box 21. The waste discharge pipe 22 and waste discharge box 21 may be made of plastic, which makes it easy to ensure sealing accuracy, prevents water leakage and odor, and eliminates problems such as poor sealing and water leakage / odor.

[0084] In this embodiment of the present invention, a toilet device is provided, as shown in Figures 17 to 27, comprising a toilet seat body 1, a waste discharge mechanism 2, and a clamp connecting part 6. The toilet seat body 1 is provided with a toilet bowl 11 and a waste discharge port 262, and a waste discharge connection part 13 is provided on the outer circumference of the waste discharge port 262, and the waste discharge connection part 13 is located outside the toilet bowl 11. One end of the waste discharge port 262 communicates with the toilet bowl 11, and the other end communicates with a passage inside the waste discharge connection part 13. The waste discharge mechanism 2 includes a waste discharge box 21, and the waste suction port of the waste discharge box 21 communicates with the passage. A waste suction connection part 23 is provided on the outer circumference of the waste suction port, which abuts and communicates with the waste discharge connection part 13 in the axial direction, and the waste suction connection part 23 protrudes from the outer wall of the waste discharge box 21. The clamp connection part 6 is fitted onto the outside of the waste suction connection part 23 and the waste discharge connection part 13, clamping and fixing the waste suction connection part 23 and the waste discharge connection part 13, thereby fixing the toilet seat body 1 and the waste discharge box 21 together.

[0085] The waste discharge mechanism 2 may further include a waste discharge pipe 22 located inside the waste discharge box 21, the waste discharge pipe 22 communicating with the waste intake and rotating relative to the waste discharge box 21 to discharge waste. The waste discharge pipe 22 and the waste discharge box 21 may be made of plastic, and the toilet seat body 1 may be made of ceramic. In some cases, the toilet seat body 1 may also be made of plastic, or the waste discharge connection part 13 of the toilet seat body 1 may be made of plastic.

[0086] Clamp connection part 6 and waste discharge connection part 13, Sewage suction connection part 23 The large contact area makes it less likely for localized connection points to be damaged by the force received. The clamp connection part 6 provides a 360° connection in the circumferential direction; in other words, the clamp connection part 6 has an annular structure. Compared to connecting with bolts or other parts placed in only a few places in the circumferential direction, the annular clamp connection part can effectively avoid situations where stress concentrates. In other words, when connecting using the clamp connection part 6, the outer edges of the waste discharge connection part 13 and the waste suction connection part 23 receive force uniformly, not just at a few points, so that the force applied to the waste discharge connection part 13 and the waste suction connection part 23 is distributed more uniformly, localized force concentration at one or a few points is avoided, and the integrity of the toilet seat body 1 and the waste discharge box 21 is protected.

[0087] Since the clamp connector 6 provides a 360° connection in the circumferential direction, it is not necessary to provide multiple clamp connectors 6 to enhance the connection effect, unlike other connectors (e.g., bolts). A single clamp connector 6 ensures a reliable connection, allowing the waste discharge connection 13 and the waste suction connection 23 to be aligned axially.

[0088] In the toilet device according to the embodiment of the present invention, the toilet seat body 1 and the waste discharge box 21 are fixedly connected with a clamp connecting part 6. The clamp connecting part 6 is easy to install, provides good positioning and connection effects, and allows the end faces of the waste discharge connection part 13 and the waste suction connection part 23 to be more tightly in contact, avoiding large gaps at the connection point between the toilet seat body 1 and the waste discharge box 21, thereby avoiding water leakage and odor problems.

[0089] In one exemplary embodiment, as shown in Figures 19, 20, 22, and 26, the waste discharge connection 13 includes a waste discharge pipe section 131 and a second annular flange 132 provided on the outer wall of the waste discharge pipe section 131, and the waste suction connection 23 includes a waste suction pipe section 231 and a first annular flange 232 provided on the outer wall of the waste suction pipe section 231, with the waste suction pipe section 231 and the waste discharge pipe section 131 communicating by abutting. The clamp connection component 6 includes a clamp body 63, a first limiting flange 61 and a second limiting flange 62, the first limiting flange 61 and the second limiting flange 62 being connected to the axial ends of the clamp body 63 and extending inward from the clamp body 63. The clamp body 63 is fitted onto the outside of the second annular flange 132 and the first annular flange 232. The second annular flange 132 and the first annular flange 232 are located between the first limiting flange 61 and the second limiting flange 62, and are clamped and fixed by the first limiting flange 61 and the second limiting flange 62.

[0090] The waste discharge pipe section 131 and the second annular flange 132 installed on the outer wall of the waste discharge pipe section 131 form a waste discharge connection section 13, and the waste suction pipe section 231 and the first annular flange 232 installed on the waste suction pipe section 231 form a waste suction connection section 23. The waste suction pipe section 231 and the waste discharge pipe section 131 are butted together and in communication, so that waste in the toilet bowl 11 flows through the waste discharge pipe section 131 into the waste suction pipe section 231 and further into the subsequent external waste discharge pipeline. The waste suction pipe section 231 and the waste discharge pipe section 131 may be located on the same straight line, so that waste can smoothly enter the waste suction pipe section 231 from the waste discharge pipe section 131.

[0091] The clamp connection component 6 connects the second annular flange 132 and the first annular flange 232, and further fixes the waste discharge connection part 13 and the waste suction connection part 23. The clamp connection component 6 includes a clamp body 63, a first limiting flange 61, and a second limiting flange 62. The clamp body 63, the first limiting flange 61, and the second limiting flange 62 surround each other to form a U-shaped limiting groove, which is used to clamp and fix the second annular flange 132 and the first annular flange 232. The clamp body 63, the second annular flange 132, and the first annular flange 232 may all be annular in shape.

[0092] When the clamp connection component 6 is clamped in place, the first limiting flange 61 and the second limiting flange 62 abut against the second annular flange 132 and the first annular flange 232, respectively, along the axial direction, thereby restricting the separation of the second annular flange 132 and the first annular flange 232 along the axial direction. The clamp connection component 6 can also restrict the radial displacement of the second annular flange 132 and the first annular flange 232. In other words, the clamp connection component 6 can achieve restriction of the relative positional relationship between the waste discharge connection portion 13 and the waste suction connection portion 23 without requiring any other auxiliary limiting components. By further installing a rotation limiting structure (e.g., a subsequent rotation prevention structure) on the clamp connection component 6, the relative position of the waste discharge connection portion 13 and the waste suction connection portion 23 can be determined and relative rotation can be prevented.

[0093] In one exemplary embodiment, as shown in Figure 22, the second annular flange 132 and the first annular flange 232 are in contact along the axial direction, and the outer wall of the second annular flange 132 is flush with the outer wall of the first annular flange 232.

[0094] By having the second annular flange 132 and the first annular flange 232 come into contact along the axial direction, the axial distance between the second annular flange 132 and the first annular flange 232 can be shortened, thereby reducing the axial dimension of the clamp connection component 6.

[0095] The outer wall of the second annular flange 132 is flush with the outer wall of the first annular flange 232. In other words, by setting the radial dimensions of the second annular flange 132 and the first annular flange 232 to be the same, the clamp connection component 6 can more easily clamp and fix the second annular flange 132 and the first annular flange 232 more effectively, and the second annular flange 132 can receive the same uniform force as the first annular flange 232.

[0096] In some cases, there may be a gap between the second annular flange 132 and the first annular flange 232 without them being in close contact. For example, an annular projection may be installed as a sealing structure on the end face of one of the annular flanges, or a sealing washer or the like may be installed between the axial end faces of the second annular flange 132 and the first annular flange 232. In this case, the axial length of the clamp connecting component 6 may be increased accordingly, and this invention is not limited thereto.

[0097] In one exemplary embodiment, as shown in Figure 22, one end of the second annular flange 132 away from the toilet bowl 11 surrounds the waste discharge pipe section 131 to form a mounting groove 263. The first annular flange 232 is located at the end of the waste suction pipe section 231 closer to the toilet bowl 11, and the waste suction pipe section 231 is fitted at least partially outside the waste discharge pipe section 131, so that the first annular flange 232 is at least partially located within the mounting groove 263 and in contact with the second annular flange 132.

[0098] One end of the second annular flange 132 that is away from the toilet bowl 11 surrounds the waste discharge pipe section 131 to form a mounting groove 263. In other words, the waste discharge pipe section 131 protrudes from the second annular flange 132 along the axial direction and further forms a mounting groove 263 with one end of the second annular flange 132. The mounting groove 263 may be a stepped groove, and one end of the mounting groove 263 facing the first annular flange 232 is installed as an open section, and the radial outer end of the mounting groove 263 is installed as an open section. The waste suction pipe section 231 may be fitted into the waste discharge pipe section 131 to facilitate assembly. In the installation process of the waste discharge mechanism 2, the waste suction pipe section 231 is first fitted onto the waste discharge pipe section 131. At this time, the waste discharge pipe section 131 can provide a certain level of support to the waste suction pipe section 231, preventing the worker from holding the waste discharge box 21 for an extended period of time, thereby reducing the intensity of the work, and allowing the worker to easily attach the clamp connection part 6 to the connection point between the second annular flange 132 and the first annular flange 232.

[0099] In one exemplary embodiment, as shown in Figure 22, a seal groove 265 is provided on the inner wall of one end of the waste suction pipe section 231 closest to the toilet bowl 11, with one end of the seal groove 265 facing the second annular flange 132 being open, and the radial inner end of the seal groove 265 being open, and a seal component 4 is provided inside the seal groove 265, with one end of the seal component 4 closest to the second annular flange 132 in contact with the second annular flange 132, and the radial inner end of the seal component 4 in contact with the outer wall of the waste discharge pipe section 131.

[0100] A seal groove 265 is installed in the waste suction pipe section 231 and used to attach the seal component 4. This improves the sealing performance of the connection between the waste discharge connection section 13 and the waste suction connection section 23, preventing water leakage and odor return from the connection section.

[0101] One end of the seal groove 265 facing the second annular flange 132 is installed as an open section, and the radial inner end of the seal groove 265 is also installed as an open section. In other words, both sides of the seal groove 265 are open, and it is in the form of a stepped groove.

[0102] The four surfaces of the sealing component 4 located within the sealing groove 265 all come into contact with each other, thereby achieving synchronous axial and radial sealing, simplifying the sealing structure, and improving the sealing effect.

[0103] In one exemplary embodiment, the distance between the first limiting flange 61 and the second limiting flange 62 gradually increases along the radially inward direction, or guide inclined surfaces are provided at the radially inward ends of the first limiting flange 61 and the second limiting flange 62.

[0104] The distance between the first limiting flange 61 and the second limiting flange 62 gradually increases, in other words, the opening of the clamp connecting component 6 gradually increases, thereby allowing the clamp connecting component 6 to be easily fitted to the outside of the second annular flange 132 and the first annular flange 232, thus avoiding situations where installation becomes difficult due to dimensional errors during installation.

[0105] Of course, guide inclined surfaces can also be installed at the radially inner ends of the first limiting flange 61 and the second limiting flange 62 to facilitate the installation of the clamp connection component 6. In other words, guide inclined surfaces can be installed at the radially inner ends of the first limiting flange 61 and the second limiting flange 62, and the opening dimension of the clamp connection component 6 can be increased in proportion to the reduction in the radial dimension. That is, the limiting groove of the clamp connection component 6 can be made to have an opening dimension (width) larger than the groove bottom dimension (width), making it easier to smoothly fit the clamp connection component 6 onto the outside of the second annular flange 132 and the first annular flange 232, and to connect and fix it.

[0106] In one exemplary embodiment, the clamp connector 6 includes a plurality of sub-hoops, which are joined together along the circumferential direction of the clamp connector 6 to form an annular structure.

[0107] The clamp connector 6 may include two sub-hoops. As shown in Figure 20, the clamp connector 6 includes a first sub-hoop 64 and a second sub-hoop 66, the first end of the first sub-hoop 64 being detachably connected to the first end of the second sub-hoop 66, and the second end of the first sub-hoop 64 being hinged or detachably connected to the second end of the second sub-hoop 66, the first sub-hoop 64 and the second sub-hoop 66 buckling together to form a complete annular structure that restricts and secures the waste discharge connection 13 and the waste suction connection 23.

[0108] A first mounting portion 641 extending radially outward is provided at the first end of the first sub-hoop 64, and a second mounting portion 661 extending radially outward is provided at the first end of the second sub-hoop 66, with the first mounting portion 641 connected to the second mounting portion 661. A third mounting portion 642 extending radially outward is provided at the second end of the first sub-hoop 64, and a fourth mounting portion 662 extending radially outward is provided at the second end of the second sub-hoop 66, with the third mounting portion 642 connected to the fourth mounting portion 662.

[0109] A first connection hole is provided in the first mounting portion 641, and a second connection hole is provided in the second mounting portion 661. The first fastener 65 is drilled through the first and second connection holes to fix and connect the first mounting portion 641 and the second mounting portion 661. A third connection hole is provided in the third mounting portion 642, and a fourth connection hole is provided in the fourth mounting portion 662. The second fastener 67 is drilled through the third and fourth connection holes to fix and connect the third mounting portion 642 and the fourth mounting portion 662.

[0110] In one exemplary embodiment, the toilet system further includes a rotation prevention structure for restricting the rotation of the waste discharge box 21 relative to the toilet seat body 1.

[0111] A rotation prevention structure is installed between the waste suction connection part 23 and the waste discharge connection part 13 to prevent the waste discharge box 21 from rotating.

[0112] The clamp connection part 6 connects and fixes the waste discharge connection part 13 and the waste suction connection part 23, restricting both in the axial direction and preventing the waste discharge box 21 from detaching rearward along the axial direction relative to the toilet seat body 1. Furthermore, by restricting both in the radial direction, radial displacement between the waste discharge box 21 and the toilet seat body 1 can be prevented. Combined with the rotation prevention structure, restricting both in the circumferential direction prevents relative rotation of the waste discharge box 21 relative to the toilet seat body 1, ensuring reliable operation of the toilet device.

[0113] In one exemplary embodiment, a protrusion is provided on one of the waste discharge connection portion 13 and the waste suction connection portion 23, and a fitting groove is provided on the other, and the rotation prevention structure includes the protrusion and the fitting groove (not shown). Alternatively, a first restricting hole is provided on the waste discharge connection portion 13, and a second restricting hole is provided on the waste suction connection portion 23, and the rotation prevention structure includes a restricting component, which is drilled in the first and second restricting holes along the axial direction of the waste suction connection portion 23, and restricts the rotation of the waste suction connection portion 23 relative to the waste discharge connection portion 13 (not shown). Alternatively, as shown in Figures 23 and 24, a non-circular first anti-rotation wall surface 261 is provided on the outer wall of the waste discharge connection part 13, a non-circular second anti-rotation wall surface 264 is provided on the waste suction connection part 23, and a third anti-rotation wall surface is provided on the inner wall of the clamp connection part 6, which matches the first anti-rotation wall surface 261 and the second anti-rotation wall surface 264. The anti-rotation structure includes the first anti-rotation wall surface 261, the second anti-rotation wall surface 264, and the third anti-rotation wall surface.

[0114] There may be multiple forms of the anti-rotation structure. For example, a protrusion may be provided on the waste discharge connection part 13, and a fitting groove may be provided on the waste suction connection part 23, and the protrusion may be inserted into the fitting groove to restrict the circumferential rotation of the waste suction connection part 23 (waste discharge box 21) relative to the waste discharge connection part 13.

[0115] Alternatively, a first restricting hole is provided in the waste discharge connection part 13, and a second restricting hole is provided in the waste suction connection part 23. A restricting component is drilled in the first and second restricting holes along the axial direction to restrict the circumferential rotation of the waste suction connection part 23 (waste discharge box 21) relative to the waste discharge connection part 13.

[0116] Alternatively, a third rotation-preventing wall surface may be provided on the inner wall of the clamp connection part 6, and a first rotation-preventing wall surface 261 and a second rotation-preventing wall surface 264 may be installed on the waste discharge connection part 13 and the waste suction connection part 23, respectively. The first rotation-preventing wall surface 261, the second rotation-preventing wall surface 264, and the third rotation-preventing wall surface are all non-circular walls, and the third rotation-preventing wall surface abuts against the first rotation-preventing wall surface 261 and the second rotation-preventing wall surface 264 along the radial direction. In other words, the clamp connection part 6 restricts the relative rotation between the waste suction connection part 23 (waste discharge box 21) and the waste discharge connection part 13.

[0117] In one exemplary embodiment, a first mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a first sealing component is provided in the first mounting groove, and the first sealing component abuts against the axial end face of the waste suction connection portion 23 and the axial end face of the waste discharge connection portion 13 to form an end face seal. and / or, a second mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a second sealing component is provided in the second mounting groove, and the second sealing component abuts against the radial inner end of the waste suction connection portion 23 and the radial outer end of the waste discharge connection portion 13 to form a radial seal.

[0118] The toilet system further includes a sealing component provided between the waste suction connection 23 and the waste discharge connection 13. By interposing the sealing component between the waste suction connection 23 and the waste discharge connection 13 and combining it with the clamping force of the clamp connection component 6, the sealing performance between the waste suction connection 23 and the waste discharge connection 13 can be further improved, ensuring that phenomena such as water leakage and odor do not occur at the connection point between the two.

[0119] The sealing component can serve as a static seal and may be made of rubber, for example.

[0120] The sealing configuration of the sealing component may be an end face seal, a radial seal, or it may have both an end face seal and a radial seal synchronously (for example, the sealing component 4 in the aforementioned sealing groove 265).

[0121] Regarding the end face seal, a first mounting groove may be installed in the waste suction connection portion 23, and the seal component is mounted in the first mounting groove along the axial direction, so that the waste discharge connection portion 13 abuts against the seal component in the first mounting groove. After connecting the waste suction connection portion 23 and the waste discharge connection portion 13, the clamp connection component 6 can exert a certain pressing effect on the seal component, in other words, the clamp connection component 6 can compress the seal component and enhance the sealing effect of the seal component.

[0122] For radial seals, a second mounting groove may be installed in the waste suction connection section 23, and the seal component may be mounted in the second mounting groove along the radial direction, with the waste discharge connection section 13 in contact with the seal component in the second mounting groove. In the radial direction, the space between the waste suction connection section 23 and the waste discharge connection section 13 may be a gap fit, and the seal component can be fitted into the second mounting groove by interlocking. In other words, the seal component is pressed against the inner wall of the waste suction connection section 23 and the outer wall of the waste discharge connection section 13, compressing the seal component and enhancing its sealing effect.

[0123] The toilet system may also be equipped with a shifter 51, which is located below the waste discharge mechanism, the inlet of the shifter 51 is connected to the outlet of the waste discharge box 21, and the outlet of the shifter 51 is connected to the outside In the waste discharge pipe They are connected. A rim spout 52 is attached to the toilet seat body 1, and the rim spout 52 is fixed to the toilet seat body 1 to draw water for flushing the toilet system.

[0124] Furthermore, the waste discharge pipe 22 forms a dynamic seal with an oil seal and a waste discharge box 21. The waste discharge pipe 22 and waste discharge box 21 may be made of plastic, which makes it easy to ensure sealing accuracy, prevents water leakage and odor, and eliminates problems such as poor sealing and water leakage / odor.

[0125] In the toilet device according to the embodiment of the present invention, a guide structure is provided between the waste discharge connection and the waste suction connection, and the guide structure is set to guide the waste suction connection to move from a set starting position to a set ending position relative to the waste discharge connection, and the waste suction connection is fitted into the waste discharge connection and is restricted by the waste discharge connection.

[0126] In the embodiment of the present invention, the toilet seat body 1 and the waste discharge box 21 are fixedly connected by a guide structure. The connection method is simple and easy to operate, the fixation is strong, the connection effect is good, and the end faces of the waste discharge connection part 13 and the waste suction connection part 23 are in close contact and easy to seal. For example, by subsequently installing a sealing part 4 between the waste suction connection part 23 and the waste discharge connection part 13, the sealing performance is further enhanced, and problems of water leakage and odor are avoided.

[0127] The toilet according to the embodiment of the present invention solves problems such as the large number of parts in the connection structure compared to connections using bolts and other components, the tendency for parts to scatter and be lost during construction, and the need for other auxiliary tools for installation. The toilet according to the embodiment of the present invention does not require the addition of separate connection parts or special mounting equipment, can be installed by hand, and is easy for workers to install.

[0128] In actual operation, the waste suction connection part 23 may be made of plastic, and the guide structure can provide a certain pre-tightening force between the waste discharge connection part 13 and the waste suction connection part 23 after connecting the waste discharge connection part 13 and the waste suction connection part 23. This causes a small deformation in the waste suction connection part 23, facilitating tight contact of the waste discharge connection part 13 and improving sealing performance.

[0129] A waste suction connection part 23 is installed at the waste suction port 211 of the waste discharge box 21, and a waste discharge connection part 13 is installed at the waste discharge port 12 of the toilet seat body 1. The installation of the waste suction connection part 23 and the waste discharge connection part 13 facilitates connection. By fixing the waste suction connection part 23 and the waste discharge connection part 13, connection of the toilet seat body 1 to the waste discharge box 21 is achieved, simplifying the connection structure and avoiding the need to drill holes or other methods to connect the main body structures of the toilet seat body 1 and the waste discharge box 21, making it efficient and practical.

[0130] The guide structure is configured to guide the waste suction connection part 23 to move from the set starting position to the set ending position relative to the waste discharge connection part 13. In other words, the waste suction connection part 23 is detachably connected to the waste discharge connection part 13, and the guide structure attaches, restricts, and fixes the waste suction connection part 23 to the waste discharge connection part 13, thereby fixing the toilet seat body 1 and the waste discharge mechanism 2.

[0131] The guide structure functions as a guide, allowing, for example, an operator to apply power to move the waste suction connection 23 in a direction (e.g., axial movement or circumferential rotation) to facilitate connection of the waste discharge connection 13.

[0132] In one exemplary embodiment, the guide structure is configured to guide the waste suction connection 23 so that it is first inserted into the waste discharge connection 13 along its axial direction from a set starting position, and then rotates along its circumferential direction relative to the waste discharge connection 13 to a set ending position.

[0133] The guide structure is configured to guide the waste suction connection part 23 from its starting position to be inserted into the waste discharge connection part 13 along its axial direction. In other words, the waste suction connection part 23 approaches the waste discharge connection part 13 axially along the guide structure and is inserted and connected to the waste discharge connection part 13.

[0134] The guide structure guides the waste suction connection part 23 to rotate along its circumferential direction relative to the waste discharge connection part 13 to a set end position. In other words, after the waste suction connection part 23 is inserted and connected to the waste discharge connection part 13, the waste suction connection part 23 rotates by a certain angle along its circumferential direction to lock the waste discharge connection part 13 with the waste suction connection part 23, preventing the waste suction connection part 23 from retracting in the opposite axial direction and separating from the waste discharge connection part 13.

[0135] The guide structure allows the waste suction connection 23 to move axially before rotating circumferentially, ensuring a reliable connection between the waste suction connection 23 and the waste discharge connection 13. Furthermore, it facilitates assembly, allows for quick installation, and improves assembly efficiency.

[0136] In one exemplary embodiment, as shown in Figures 36 to 38, the guide structure comprises a guide groove 1311, a rotating groove 1312, a stopper projection 1313, and a guide projection 2311. The guide groove 1311, the rotating groove 1312, and the stopper projection 1313 are provided on one of the waste discharge connection section 13 and the waste suction connection section 23, while the guide projection 2311 is provided on the other. The guide groove 1311 communicates with the rotating groove 1312 and is installed adjacent to it along the axial direction of the waste suction connection section 23. The stopper projection 1313 and the guide groove 1311 are installed adjacent to each other along the circumferential direction of the waste suction connection section 23. The guide groove 1311 is for the guide projection 2311 to penetrate the guide groove 1311 from a set starting position along the axial direction of the waste suction connection section 23 and enter the rotating groove 1312. The rotating groove 1312 is for the guide projection 2311 to rotate relative to the waste discharge connection 13 along the circumferential direction of the waste suction connection 23. The stopper projection 1313, together with the guide projection 2311, restricts the waste suction connection 23 from detaching from the waste discharge connection 13 when the guide projection 2311 rotates to its set end position, thereby restricting the waste suction connection 23 to the waste discharge connection 13.

[0137] A guide groove 1311, a rotating groove 1312, and a stopper projection 1313 may be installed in the waste discharge connection section 13. The rotating groove 1312 is installed on the side of the guide groove 1311 away from the waste suction connection section 23, and the rotating groove 1312 communicates with the guide groove 1311. The guide projection 2311 moves axially within the guide groove 1311 and enters the rotating groove 1312. The guide projection 2311 rotates circumferentially within the rotating groove 1312 to a set end position, preventing the guide projection 2311 from detaching from the guide groove 1311. When the guide projection 2311 rotates circumferentially to the set end position within the rotating groove 1312, the stopper projection 1313 abuts against the guide projection 2311 axially, preventing the guide projection 2311 from retracting axially and detaching, and further tightens and connects the waste suction connection section 23 and the waste discharge connection section 13.

[0138] A guide projection 2311 is installed in the waste suction connection section 23, and the guide projection 2311 is aligned with the guide groove 1311 and the rotation groove 1312.

[0139] In addition to the above installation method, a guide groove 1311, a rotating groove 1312, and a stopper projection 1313 may be installed in the waste suction connection part 23, and a guide projection 2311 may be installed in the waste discharge connection part 13.

[0140] In one exemplary embodiment, as shown in Figure 36, the waste suction connection 23 is fitted to the outside of the waste discharge connection 13, the waste discharge connection 13 includes a waste discharge pipe 1314 and a second annular flange 132 provided on the outer wall of the waste discharge pipe 1314, the second annular flange 132 is provided with a notch that forms a guide groove 1311, the portion of the second annular flange 132 adjacent to the notch forms a stopper projection 1313, one end of the second annular flange 132 closer to the toilet bowl 11 surrounds the waste discharge pipe 1314 to form a rotation groove 1312, and the guide projection 2311 is provided on the inner wall of the waste suction connection 23.

[0141] As shown in Figure 36, the notches may be installed on the outer circumferential surface of the second annular flange 132, and the notches penetrate the second annular flange 132 along the axial direction, thereby allowing the guide projection 2311 to enter the rotation groove 1312 through the notches. Multiple notches may be installed evenly in the circumferential direction of the second annular flange 132; for example, there may be three notches.

[0142] The waste suction connection part 23 is fitted to the outside of the waste discharge connection part 13, the guide projection 2311 is installed on the inner wall of the waste suction connection part 23, and the guide groove 1311 and the rotating groove 1312 are installed on the outer wall of the waste discharge connection part 13.

[0143] The waste discharge connection section 13 includes a waste discharge pipe section 1314 and a second annular flange 132. The second annular flange 132 may be an integrated structure, and multiple notches are evenly spaced in the circumferential direction of the second annular flange 132. Multiple guide protrusions 2311 are correspondingly installed on the inner wall of the waste suction connection section 23. Stopper protrusions 1313 are located between adjacent notches.

[0144] The rotating groove 1312 may also be a 360° annular groove.

[0145] In one exemplary embodiment, as shown in Figure 38, the guide projection 2311 is provided on one end of the inner wall of the waste suction connection 23 closest to the toilet bowl 11.

[0146] The guide projection 2311 is installed at the end of the waste suction connection part 23 and aligns with the guide groove 1311 and the rotating groove 1312 of the waste discharge connection part 13.

[0147] In one exemplary embodiment, the toilet further includes a rotation prevention structure to restrict the rotation of the waste discharge box 21 relative to the toilet seat body 1.

[0148] A rotation prevention structure is installed between the waste suction connection part 23 and the waste discharge connection part 13 to prevent the waste discharge box 21 from rotating.

[0149] The guide mechanism connects and fixes the waste discharge connection 13 and the waste suction connection 23, restricting both in the axial direction. After the guide projection passes through the guide groove 1311 and enters the rotating groove, the waste suction connection 23 rotates by a certain angle, causing the stopper projection 1313 to abut against the guide projection 2311 along the axial direction, preventing the guide projection 2311 from retracting and detaching along the axial direction. Furthermore, the guide mechanism tightens and connects the waste suction connection 23 and the waste discharge connection 13, achieving axial restriction and fixation of the waste discharge connection 13 and the waste suction connection 23. However, when the waste discharge box 21 is subjected to circumferential forces, the guide mechanism cannot provide circumferential restriction. By providing a rotation prevention structure between the waste suction connection part 23 and the waste discharge connection part 13, the waste discharge box 21 can be prevented from rotating relative to the toilet seat body 1 due to circumferential forces. Furthermore, the waste discharge box 21 is completely fixed and restricted, preventing it from moving or rotating during operation and ensuring the reliable operation of the toilet.

[0150] In one exemplary embodiment, as shown in Figures 29, 30, 31, 34, and 36, a first restricting hole 1316 is provided in the waste discharge connection 13 and a second restricting hole 2312 is provided in the waste suction connection 23. The rotation prevention structure includes a restricting component 7, which is drilled in the first restricting hole 1316 and the second restricting hole 2312 along the axial direction of the waste suction connection 23 to restrict the rotation of the waste suction connection 23 relative to the waste discharge connection 13.

[0151] After inserting and connecting the waste suction connection part 23 and the waste discharge connection part 13, the waste suction connection part 23 rotates by a certain angle along the circumferential direction to lock the waste discharge connection part 13 with the waste suction connection part 23 and restrict movement in the axial direction. After the waste suction connection part 23 moves from the set start position to the set end position relative to the waste discharge connection part 13, the first restriction hole 1316 and the second restriction hole 2312 become flush in the axial direction, and the restriction part 7 is drilled in the first restriction hole 1316 and the second restriction hole 2312 to restrict movement in the circumferential direction and restrict the rotation of the waste suction connection part 23 relative to the waste discharge connection part 13.

[0152] The rotation prevention structure may take other forms. For example, a limiting groove may be provided in the rotation groove 1312, and a limiting portion may be provided on the guide projection 2311. After the guide projection 2311 rotates along the rotation groove 1312 by a certain angle, the limiting portion engages with the limiting groove and restricts it, thereby preventing the waste suction connection portion 23 from rotating further relative to the waste discharge connection portion 13.

[0153] In one exemplary embodiment, as shown in Figure 36, the waste suction connection 23 is fitted to the outside of the waste discharge connection 13, a protrusion 133 is provided on the outer wall of the waste discharge connection 13, the protrusion 133 and the guide structure are offset along the axial direction of the waste suction connection 23, the first restricting hole 1316 is provided in the protrusion 133, the second restricting hole 2312 is provided in the waste suction connection 23, and one end of the second restricting hole 2312 extends to the end face of the waste suction connection 23 closest to the toilet bowl 11, forming an opening that contributes to the attachment of the restricting component 7.

[0154] A protrusion 133 is added to the outer wall of the waste discharge connection section 13, and the protrusion 133 is for opening the first restriction hole 1316. The protrusion 133 and the guide structure are offset in the axial direction, and the guide structure is positioned to protrude from the side away from the waste suction connection section 23.

[0155] The first limiting hole 1316 may be installed on the stopper projection 1313.

[0156] In one exemplary embodiment, as shown in Figure 31, the limiting component 7 includes a limiting rod 71 and a push-pull projection 72 mounted on the limiting rod 71. The push-pull projection 72 is configured to move the limiting rod 71 along the axial direction of the sewage suction connection 23. The sewage suction connection 23 is further provided with a push-pull groove 2313, one end of which communicates with a second limiting hole 2312, and the other end of which penetrates the sewage suction connection 23 radially. The push-pull projection 72 is movably positioned within the push-pull groove 2313 and protrudes from the push-pull groove 2313.

[0157] The limiting component 7 may include a limiting rod 71 and a push-pull projection 72 installed on the limiting rod 71, and the operator can move the limiting rod 71 along the axial direction by pushing the push-pull projection 72. The waste suction connection part 23 is further provided with a push-pull groove 2313 for the push-pull projection 72 to slide on.

[0158] One end of the push-pull groove 2313 communicates with the second limiting hole 2312, and the other end of the push-pull groove 2313 extends radially along the waste suction connection part 23 to the outer circumferential surface of the waste suction connection part 23, forming an opening on the outer circumferential surface. In other words, the push-pull groove 2313 communicates with the second limiting hole 2312, allowing the push-pull projection 72 to move along the axial direction of the push-pull groove 2313, and the limiting rod 71 to move along the axial direction of the second limiting hole 2312.

[0159] In one exemplary embodiment, the limiting component 7 is set to be movable between a first position and a second position along the axial direction of the waste suction connection 23. When the limiting component 7 is moved to the first position, it penetrates the first limiting hole 1316 and the second limiting hole 2312, restricting the rotation of the waste suction connection 23 relative to the waste discharge connection 13. When the limiting component 7 is moved to the second position, it disengages from the first limiting hole 1316 and / or the second limiting hole 2312, allowing the waste suction connection 23 to rotate relative to the waste discharge connection 13.

[0160] When the restricting component 7 moves to the first position, that is, when the restricting component 7 is simultaneously positioned in the first restricting hole 1316 and the second restricting hole 2312, the restricting rod 71 plays a role in restricting the relative rotation between the waste discharge connection part 13 and the waste suction connection part 23, thereby ensuring a secure connection between the waste discharge mechanism 2 and the toilet seat body 1.

[0161] When the restricting component 7 moves to the second position, that is, when the restricting rod 71 moves axially so that it is positioned only in the first restricting hole 1316 or only in the second restricting hole 2312, the circumferential restriction is released, making it easier to disassemble and assemble the waste discharge mechanism 2.

[0162] In one exemplary embodiment, the anti-rotation structure further comprises an elastic component 74 that engages with the limiting component 7, as shown in Figure 31, and the elastic component 74 is configured to use its restorative elastic force to position the limiting component 7 in a first position, or the anti-rotation structure further comprises a magnetic component (not shown) installed opposite the limiting component 7, and the magnetic component is configured to use its magnetic field force to position the limiting component 7 in a first position.

[0163] The rotation prevention structure may further include an elastic component 74 or a magnetic component that is coupled with the limiting component 7. The elastic component 74 or magnetic component acts a restorative elastic force or magnetic field force on the limiting component 7, keeping the limiting component 7 in the first position, that is, when the limiting component 7 is always simultaneously in the first limiting hole 1316 and the second limiting hole 2312, it restricts the relative rotation between the waste discharge connection 13 and the waste suction connection 23.

[0164] The elastic component 74 may be a spring, with one end in contact with the limiting component 7 and the other end in contact with the first limiting hole 1316 or the second limiting hole 2312, thereby simultaneously positioning the limiting component 7 within the first limiting hole 1316 and the second limiting hole 2312. The magnetic component may be a magnet, with the magnet located within the first limiting hole 1316 or the second limiting hole 2312, and one end of the limiting component 7 facing the magnet being a magnetic or metallic material, so that the limiting component 7 is simultaneously positioned within the first limiting hole 1316 and the second limiting hole 2312 due to the attractive or repulsive force exerted by the magnetic component on the limiting component 7.

[0165] If it is necessary to remove the waste discharge mechanism 2, the operator manually pushes the push-pull projection 72 to move the limiting rod 71 to the second position against the return elastic force of the elastic component 74 or the magnetic field force of the magnetic component.

[0166] In one exemplary embodiment, as shown in Figure 31, the limiting component 7 includes a limiting rod 71 and a first mounting plate 73 mounted on the limiting rod 71, the first mounting plate 73 having a first mounting hole 731. The anti-rotation structure further includes a connecting component 75, which passes through the first mounting hole 731 and restricts the limiting component 7 to move within a first limiting hole 1316 or a second limiting hole 2312, and prevents the limiting component 7 from detaching from the first limiting hole 1316 or the second limiting hole 2312. The connecting component 75 may be a screw.

[0167] A first mounting plate 73 may be installed on the limiting rod 71, and a first mounting hole 731 may be installed in the first mounting plate 73. A connecting component 75 is inserted through the first mounting hole 731 to restrict the limiting rod 71 so that it can move between the first limiting hole 1316 and the second limiting hole 2312. Even after the limiting rod 71 is restricted by the first mounting plate 73, the connecting component 75 can move the limiting rod 71 along the axial direction between the first and second positions, but it is possible to prevent the limiting rod 71 from directly detaching from the first limiting hole 1316 and the second limiting hole 2312.

[0168] As shown in Figure 30, a septic tank connection section 23 may be provided with a septic tank groove 233 that communicates with the second limiting hole 2312, and the first mounting plate 73 is attached to the septic tank groove 233.

[0169] By installing the first mounting plate 73 and fixing it via the connecting part 75, it is possible to prevent the limiting rod 71 from easily coming out of the first limiting hole 1316 or the second limiting hole 2312 during actual installation, and furthermore, it is possible to prevent the operator from manually fixing the limiting rod 71, making the installation work easier for the worker.

[0170] In one exemplary embodiment, a first mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a first sealing component 4 is provided in the first mounting groove, and the first sealing component 4 abuts against the axial end face of the waste suction connection portion 23 and the axial end face of the waste discharge connection portion 13 to form an end face seal. and / or, a second mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a second sealing component 4 is provided in the second mounting groove, and the second sealing component 4 abuts against the radial inner end of the waste suction connection portion 23 and the radial outer end of the waste discharge connection portion 13 to form a radial seal.

[0171] As shown in Figure 34, the toilet further includes a sealing component 4 provided between the waste suction connection 23 and the waste discharge connection 13.

[0172] By interposing a sealing component 4 between the waste suction connection 23 and the waste discharge connection 13, and combining the clamping force of the guide projection 2311 and the stopper projection 1313, the sealing performance between the waste suction connection 23 and the waste discharge connection 13 can be further improved, ensuring that phenomena such as water leakage and odor do not occur at the connection point between the two. The sealing component 4 can perform the role of a static seal and may be made of rubber, for example.

[0173] The sealing configuration of the sealing component 4 may be an end face seal, a radial seal, or it may have both an end face seal and a radial seal synchronously.

[0174] For the end face seal, a first mounting groove is installed in the waste suction connection part 23, the seal component 4 is mounted in the first mounting groove along the axial direction, and the waste discharge connection part 13 abuts against the seal component 4 in the first mounting groove. After connecting the waste suction connection part 23 and the waste discharge connection part 13, the guide projection 2311 and the stopper projection 1313 can exert a certain pressing effect on the seal component 4. In other words, the guide projection 2311 and the stopper projection 1313 can compress the seal component 4, thereby enhancing the sealing effect of the seal component 4.

[0175] Regarding the radial seal, a second mounting groove is installed in the waste suction connection part 23, and the seal part 4 is positioned radially. inside the second mounting groove The waste discharge connection portion 13 is attached to the second mounting groove, and the waste discharge connection portion 13 abuts against the seal component 4. In the radial direction, the space between the waste suction connection portion 23 and the waste discharge connection portion 13 may be a gap fit, and the seal component 4 can be fitted into the second mounting groove by interlocking. In other words, the seal component 4 is pressed by the inner wall of the waste suction connection portion 23 and the outer wall of the waste discharge connection portion 13, compressing the seal component 4 and enhancing its sealing effect.

[0176] During the installation process, the waste discharge box 21 is tilted at a certain angle, the guide projection 2311 of the waste discharge box 21 is aligned with the guide groove 1311 of the toilet seat body 1, the waste discharge box 21 is pushed along the axial direction, the guide projection 2311 is engaged with the rotation groove 1312 through the guide groove 1311, and then the waste discharge box 21 is rotated at a certain angle to restrict and fix it in place, at which point the outlet of the waste discharge box 21 faces downwards and the waste discharge box 21 is locked to the toilet seat body 1.

[0177] The toilet may also be equipped with a shifter 51, which is located below the waste discharge mechanism 2, with the inlet of the shifter 51 communicating with the outlet of the waste discharge box 21, and the outlet of the shifter 51 communicating with the external waste discharge piping. A rim spout 52 is attached to the toilet seat body 1, and the rim spout 52 is fixed to the toilet seat body 1 to draw water for toilet flushing.

[0178] Embodiments of the present invention provide a toilet device, as shown in Figures 42 to 53, comprising a toilet seat body 1 and a waste discharge mechanism 2, the toilet seat body 1 having a toilet bowl 11, the toilet bowl 11 communicating with a waste discharge port 12 of the toilet seat body 1, a waste discharge connection part 13 provided on the outer circumference of the waste discharge port 12, the waste discharge connection part 13 located outside the toilet bowl 11 and having a passage that communicates with the waste discharge port 12, and the waste discharge mechanism 2 having a waste discharge box The waste discharge box 21 includes a waste suction port, the waste suction port of the waste discharge box 21 is connected to a passage, a waste suction connection part 23 is provided on the outer circumference of the waste suction port, the waste suction connection part 23 protrudes from the outer wall of the waste discharge box 21, the waste discharge connection part 13 is fitted to the outside of the waste suction connection part 23, or the waste suction connection part 23 is fitted to the outside of the waste discharge connection part 13, supporting the waste discharge mechanism 2 and attaching the waste discharge mechanism 2 to the toilet seat body 1.

[0179] The waste discharge mechanism 2 may include a waste discharge pipe 22 located inside the waste discharge box 21. The waste discharge pipe 22 communicates with the waste intake and can rotate relative to the waste discharge box 21 to discharge waste. The waste discharge pipe 22 and the waste discharge box 21 may be made of plastic, and the toilet seat body 1 may be made of ceramic.

[0180] The waste suction connection 23 is fitted to the outside of the waste discharge connection 13, and the connection between the two may be a tight fit, which can improve connection reliability. Of course, in actual applications, a sealing structure can be provided here to further prevent problems such as water leakage and odor return in order to improve the connection seal.

[0181] In the toilet device according to the embodiment of the present invention, the toilet seat body 1 and the waste discharge box 21 are fixedly connected by fitting, making installation easy, subsequent removal and replacement easy, and ensuring a tighter contact surface between the waste discharge connection part 13 and the waste suction connection part 23, thereby avoiding water leakage and odor problems to a certain extent.

[0182] In actual operation, the waste suction connection part 23 may be made of plastic, and after generating a certain pressing force through tight fitting, a small deformation occurs in the waste suction connection part 23, which can tightly seal the waste discharge connection part 13 and improve sealing performance.

[0183] A waste suction connection part 23 is installed at the waste suction port of the waste discharge box 21, and a waste discharge connection part 13 is installed at the waste discharge port 12 of the toilet seat body 1. The installation of the waste suction connection part 23 and the waste discharge connection part 13 facilitates connection. By fixing the waste suction connection part 23 and the waste discharge connection part 13, the connection of the toilet seat body 1 to the waste discharge box 21 is achieved, simplifying the connection structure and avoiding the need to drill holes or other methods to connect the main body structures of the toilet seat body 1 and the waste discharge box 21, making it efficient and practical.

[0184] In one exemplary embodiment, the toilet system further includes a detachment prevention structure to restrict the waste suction connection 23 from detaching from the waste discharge connection 13.

[0185] The toilet unit is further equipped with a detachment prevention structure, which is designed to prevent the waste suction connection 23 from detaching from the waste discharge connection 13 along the axial direction, thereby further enhancing the reliability of the connection and improving the service life of the toilet unit.

[0186] The detachment prevention structure may take multiple forms. For example, a limiting block or the like may be installed to prevent the waste suction connection part 23 from retracting along the axial direction, or a contact structure may be installed at the rear end of the waste suction connection part 23 (the rear end of the waste discharge mechanism 2) to prevent the waste suction connection part 23 from retracting along the axial direction.

[0187] In one exemplary embodiment, as shown in Figures 51 and 52, the detachment prevention structure includes a first limiting component 8, which is located on the rear side of the waste discharge mechanism 2 and in contact with the rear of the waste discharge mechanism 2 and the toilet seat body 1, and the first limiting component 8 is connected to at least one of the waste discharge mechanism 2 and the toilet seat body 1.

[0188] The first restricting component 8 is installed at the rear of the waste discharge mechanism 2 and contacts both the waste discharge mechanism 2 and the toilet seat body 1, respectively, and abuts against the waste discharge mechanism 2, restricting its movement in the axial direction and preventing the waste discharge mechanism 2 from detaching to the rear.

[0189] The first restricting component 8 may have its lower end fixed to the toilet seat body 1 and its upper end in contact with the waste discharge mechanism 2. Of course, the first restricting component 8 may also have its upper end fixed to the waste discharge mechanism 2 and its lower end in contact with the toilet seat body 1.

[0190] In one exemplary embodiment, as shown in Figures 51 and 52, a second mounting plate 266 is provided at the bottom of the toilet seat body 1, a second mounting hole 267 is provided in the second mounting plate 266, the lower end of the first restricting component 8 is supported by the second mounting plate 266, a fastener 84 is fixedly connected to the first restricting component 8 through the second mounting hole 267 to fix the first restricting component 8 to the toilet seat body 1, and the upper end of the first restricting component 8 abuts against the rear of the waste discharge mechanism 2.

[0191] A second mounting plate 266 is installed on the lower part of the toilet seat body 1. The second mounting plate 266 is installed on the inner wall of the toilet seat body 1, is installed horizontally, and extends inward. The second mounting plate 266 has a limiting hole for aligning with the first limiting component 8. The lower end of the first limiting component 8 is fixed to the second mounting plate 266, and the upper end of the first limiting component 8 abuts against the rear end of the waste discharge mechanism 2, restricting it in the axial direction and preventing the waste discharge mechanism 2 from detaching to the rear.

[0192] In one exemplary embodiment, as shown in Figures 51 and 52, the first limiting component 8 includes a connecting plate 81, a support plate 82, and a reinforcing plate 83. The connecting plate 81 is supported by a second mounting plate 266 and is fixedly connected to the toilet seat body 1 by fasteners 84. The lower end of the support plate 82 is connected to the second mounting plate 266, and the upper end of the support plate 82 abuts against the rear of the waste discharge mechanism 2. The reinforcing plate 83 is connected to the rear surface of the support plate 82 and the connecting plate 81.

[0193] Both the connecting plate 81 and the support plate 82 extend along the height direction, and the reinforcing plate 83 is installed along the horizontal direction. The lower end of the connecting plate 81 is connected to the second mounting plate 266 of the toilet seat body 1, and the lower end of the connecting plate 81 may also extend from the horizontal plate along the horizontal direction; in other words, the connecting plate 81 as a whole may be an L-shaped plate. In Figure 52, only the horizontal plate portion of the L-shaped connecting plate 81 is shown, and the vertical plate portion is obscured. Two support plates 82 are installed, located on the left and right sides of the connecting plate 81, respectively.

[0194] The reinforcing plate 83 is intended to improve the strength and overall height of the first limiting component 8, and to prevent the first limiting component 8 from bending and affecting the contact limiting effect when it contacts the waste discharge mechanism 2 along the axial direction.

[0195] In one exemplary embodiment, as shown in Figures 51 and 52, the waste discharge mechanism 2 further comprises a drive unit 269 located on the rear side of the waste discharge box 21, and the first limiting component 8 is in contact with the waste discharge box 21 and offset from the drive unit 269.

[0196] The drive unit 269 rotates the L-shaped waste discharge pipe 22 inside the waste discharge box 21 to achieve rotational waste discharge. By offsetting the drive unit 269 and the first limiting component 8, the axial length of the "waste discharge mechanism 2 + first limiting component 8" is shortened, making it easier to control the dimensions of the toilet.

[0197] In one exemplary embodiment, as shown in Figures 44 and 45, the toilet system further comprises a shifter 51 fixedly connected to the waste discharge box 21, the inlet of the shifter 51 communicating with the waste discharge port of the waste discharge box 21, and the outlet of the shifter 51 to the outside In the waste discharge pipe They communicate. The detachment prevention structure includes a second limiting component 85 installed on the shifter 51, and the second limiting component 85 abuts against the rear of the toilet seat body 1.

[0198] The toilet unit may also be equipped with a shifter 51, which is located below the waste discharge mechanism 2, with the inlet of the shifter 51 communicating with the outlet of the waste discharge box 21, and the outlet of the shifter 51 communicating with the external waste discharge piping, thereby making the installation position of the toilet unit more flexible and improving user choice.

[0199] The shifter 51 and the waste discharge box 21 are fixedly connected, and the second restricting component 85 is installed on the shifter 51 to restrict and fix the shifter 51, and further restrict and fix the waste discharge box 21. There is no need to directly contact the waste discharge box 21 with the second restricting component 85, and there is no need to extend the second restricting component 85 in the height direction to contact the toilet seat body 1 again. Since the second restricting component 85 comes into direct contact with the rear of the toilet seat body 1 after being installed on the shifter 51, the length dimension of the second restricting component 85 can be reduced, and the placement of the second restricting component 85 is also easy.

[0200] In one exemplary embodiment, as shown in Figures 44 and 45, the second limiting component 85 includes a contact plate, one end of which is fixedly connected to the shifter 51, and the other end of which contacts the inner wall of the toilet seat body 1.

[0201] The second limiting component 85 may be in the form of a contact plate, achieving a contact limiting effect with small dimensions.

[0202] The second limiting component 85 may be in other forms, such as a limiting rod, and the present invention is not limited thereto.

[0203] In one exemplary embodiment, as shown in Figures 47 and 49, a guide inclined surface 268 is provided at one end of the waste suction connection 23 closest to the toilet bowl 11.

[0204] A guide inclined surface is provided at one end of the waste discharge connection section 13 that is separated from the toilet bowl 11.

[0205] Since guide inclined surfaces can be installed on both the waste suction connection section 23 and the waste discharge connection section 13, the installation of the waste suction connection section 23 into the waste discharge connection section 13 becomes easier, improving the efficiency of the installation work.

[0206] The diameter of the guide inclined surface 268 on the inner wall surface of the waste suction connection part 23 is large. One It is installed facing the waste discharge connection section 13. The end with the smaller diameter of the guide inclined surface on the outer circumferential surface of the waste discharge connection section 13 is installed facing the waste suction connection section 23. In other words, when assembling the waste suction connection section 23 and the waste discharge connection section 13, the end with the smaller diameter of the guide inclined surface on the outer circumferential surface of the waste discharge connection section 13 is first passed through the end with the larger diameter of the guide inclined surface 268 on the inner wall surface of the waste suction connection section 23, and then the waste discharge connection section 13 is further extended into the waste suction connection section 23 to complete the assembly.

[0207] In one exemplary embodiment, the fitted length of the sewage discharge connection 13 and the sewage suction connection 23 is 25 mm or more and 94 mm or less.

[0208] The length of the waste suction connection part 23 that is fitted into the waste discharge connection part 13 is 25 mm to 94 mm, ensuring connection strength while also facilitating the installation of sealing components in the overlapping portions.

[0209] In one exemplary embodiment, a rotation prevention structure is provided between the waste suction connection 23 and the waste discharge connection 13 to restrict the rotation of the waste discharge box 21 relative to the toilet seat body 1.

[0210] A rotation prevention structure is installed between the waste suction connection part 23 and the waste discharge connection part 13 to prevent the waste discharge box 21 from rotating.

[0211] The detachment prevention structure is located at the waste suction connection part 23 to waste discharge connection part 13By bringing the two parts into contact and fixing them, and restricting both in the axial direction, the waste discharge box 21 is prevented from detaching rearward along the axial direction relative to the toilet seat body 1. However, while the waste discharge box 21 is subjected to circumferential forces, the fastener 84 cannot provide circumferential restriction. By providing a rotation prevention structure between the waste suction connection part 23 and the waste discharge connection part 13, the waste discharge box 21 is prevented from rotating relative to the toilet seat body 1 due to circumferential forces, and furthermore, the waste discharge box 21 is completely fixed and restricted, preventing the waste discharge box 21 from moving or rotating during operation, and ensuring the reliable operation of the toilet device.

[0212] In one exemplary embodiment, as shown in Figures 43, 44, 48, and 49, a protrusion 133 is provided on the outer wall of the waste discharge connection 13, and a receiving groove 233 that fits with the protrusion 133 is provided on the waste suction connection 23, and the rotation prevention structure comprises the protrusion 133 and the receiving groove 233. Alternatively, a non-circular first rotation prevention wall surface is provided on the outer wall of the waste discharge connection 13, and a second rotation prevention wall surface that fits with the first rotation prevention wall surface is provided on the waste suction connection 23, and the rotation prevention structure comprises the first rotation prevention wall surface and the second rotation prevention wall surface.

[0213] The outer wall of the waste discharge connection section 13 is provided with a non-circular first anti-rotation wall surface, and the inner wall of the waste suction connection section 23 is provided with a second anti-rotation wall surface. The first and second anti-rotation wall surfaces are non-circular walls of the same shape, preventing the waste discharge box 21 from rotating relative to the toilet seat body 1.

[0214] The waste suction connection part 23 is fitted to the outside of the flange, and the first rotation-preventing wall surface is brought into close contact with the second rotation-preventing wall surface along the radial direction. Since both the first rotation-preventing wall surface and the second rotation-preventing wall surface are non-circular, relative rotation between the first rotation-preventing wall surface and the second rotation-preventing wall surface, that is, rotation of the waste discharge mechanism 2 relative to the toilet seat body 1, can be avoided.

[0215] For example, the first and second anti-rotation walls may be irregular rings formed by arcs and straight lines, and together they can serve as circumferential restraints. Of course, the first and second anti-rotation walls may also be other shapes that can prevent relative rotation, such as ellipses or polygons.

[0216] The first and second anti-rotation walls together form an anti-rotation structure.

[0217] In addition to the above-described forms of the first and second anti-rotation wall surfaces, the anti-rotation structure may adopt other forms. For example, a protrusion 133 may be provided on the waste discharge connection part 13, and a corresponding receiving groove 233 may be provided on the waste suction connection part 23, and the protrusion 133 may engage with the receiving groove 233 along the axial direction to exert an anti-rotation effect. An annular flange may be installed on the outside of the waste discharge connection part 13, and a protrusion 133 may be installed on the annular flange to restrict rotation. This annular flange may have a sealing groove formed in the axial direction for attaching a sealing component, at a certain axial distance from the annular flange at the end of the waste discharge connection part 13.

[0218] In one exemplary embodiment, as shown in Figure 47, a first mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a first sealing component is provided in the first mounting groove, and the first sealing component abuts against the radial inner end of the waste suction connection portion 23 and the radial outer end of the waste discharge connection portion 13 to form a radial seal. and / or, a second mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and a second sealing component is provided in the second mounting groove, and the second sealing component abuts against the axial end face of the waste suction connection portion 23 and the axial end face of the waste discharge connection portion 13 to form an end face seal.

[0219] The sealing configuration of the sealing component may be an end face seal, a radial seal, or it may have both an end face seal and a radial seal simultaneously.

[0220] Regarding the radial seal, a first mounting groove may be installed in the waste suction connection part 23, and the seal component is positioned radially. inside the first mounting groove The waste discharge connection portion 13 is mounted so that it abuts against the sealing component in the first mounting groove. In the radial direction, the space between the waste suction connection portion 23 and the waste discharge connection portion 13 may be a gap fit, and the sealing component can be fitted into the first mounting groove by interlocking. In other words, the sealing component is pressed against the inner wall of the waste suction connection portion 23 and the outer wall of the waste discharge connection portion 13, compressing the sealing component and enhancing its sealing effect.

[0221] Regarding the end face seal, a second mounting groove may be installed in the waste suction connection portion 23, and the seal component is mounted in the second mounting groove along the axial direction, so that the waste discharge connection portion 13 abuts against the seal component in the second mounting groove. The detachment prevention structure can exert a certain pressing effect on the seal component after the waste suction connection portion 23 and the waste discharge connection portion 13 are connected, in other words, the detachment prevention structure can compress the seal component and enhance the sealing effect of the seal component.

[0222] Furthermore, the waste discharge pipe 22 can be rotatably mounted inside the waste discharge box 21, and an oil seal can be installed at the rotatable connection to form a dynamic seal, thereby improving the sealing performance of the connection.

[0223] A rim spout 52 is attached to the toilet seat body 1, and the rim spout 52 is fixed to the toilet seat body 1 to draw water for flushing the toilet.

[0224] In this embodiment of the present invention, a toilet device is provided, as shown in Figures 54 to 63. The toilet device comprises a toilet seat body 1, a waste discharge mechanism 2, and a fastener 2414. The toilet seat body 1 is provided with a toilet bowl 11 and a waste discharge port 12 communicating with the toilet bowl 11. A waste discharge connection part 13 is provided on the outer circumference of the waste discharge port 12. The waste discharge connection part 13 is located outside the toilet bowl 11 and has a passage that communicates with the waste discharge port 12. The waste discharge mechanism 2 comprises a waste discharge box 21. The waste discharge box 21 is provided with a waste suction port 211 that communicates with the passage. A waste suction connection part 23 is provided on the outer circumference of the waste suction port 211. The waste suction connection part 23 protrudes from the outer wall of the waste discharge box 21. The waste discharge connection part 13 and the waste suction connection part 23 are fixedly connected via the fastener 2414, thereby fixing the toilet seat body 1 and the waste discharge box 21. The fastener 2414 may also be a screw connector.

[0225] The waste discharge mechanism 2 may include a waste discharge pipe 22 located inside the waste discharge box 21, which communicates with the waste intake port 211 and can rotate relative to the waste discharge box 21 to discharge waste. The waste discharge pipe 22 and the waste discharge box 21 may be made of plastic, and the toilet seat body 1 may be made of ceramic.

[0226] The connection effect can be enhanced by installing multiple fasteners 2414 along the circumferential direction of the waste discharge box 21. For example, by evenly installing multiple groove structures for connecting one end of the fastener 2414 on the outer surface of the waste suction connection part 23, the toilet seat body 1 and the waste discharge box 21 receive force evenly, preventing distortion after connection and avoiding detachment. In actual application, three fasteners 2414 may be installed and evenly arranged along the circumferential direction.

[0227] In the toilet device according to the embodiment of the present invention, the toilet seat body 1 and the waste discharge box 21 are fixedly connected with fasteners 2414. The fasteners 2414 ensure secure connection and good connection effect, allowing the end faces of the waste discharge connection part 13 and the waste suction connection part 23 to be more tightly fitted together. This avoids large gaps at the connection point between the toilet seat body 1 and the waste discharge box 21, thus avoiding water leakage and odor problems.

[0228] In actual operation, the waste suction connection part 23 may be made of plastic, and after a certain pressing force is applied to the fastener 2414, a small deformation occurs in the waste suction connection part 23, which can make the waste discharge connection part 13 fit more tightly and improve the sealing performance.

[0229] A waste suction connection part 23 is installed at the waste suction port 211 of the waste discharge box 21, and a waste discharge connection part 13 is installed at the waste discharge port 12 of the toilet seat body 1. The installation of the waste suction connection part 23 and the waste discharge connection part 13 facilitates connection. By fixing the waste suction connection part 23 and the waste discharge connection part 13, connection of the toilet seat body 1 to the waste discharge box 21 is achieved, simplifying the connection structure and avoiding the need to drill holes or other methods to connect the main body structures of the toilet seat body 1 and the waste discharge box 21, making it efficient and practical.

[0230] In one exemplary embodiment, as shown in Figures 55 to 61, the fastener 2414 includes a bolt 2415 and a nut 2416, and a connecting hole 2411 is provided in at least one of the waste suction connection 23 and the waste discharge connection 13, the bolt 2415 is drilled into the connecting hole 2411 and screwed onto the nut 2416 to fasten the waste suction connection 23 and the waste discharge connection 13.

[0231] A connection hole 2411 is provided in the waste suction connection section 23, one end of a bolt 2415 is fixed to the waste suction connection section 23, and the other end of the bolt 2415 extends through the connection hole 2411 in the waste suction connection section 23 toward the waste discharge connection section 13, and a nut 2416 is screwed onto the extended portion (other end) of the bolt 2415, that is, the nut 2416 is screwed onto the end of the bolt 2415 to fasten the waste suction connection section 23 and the waste discharge connection section 13. One end of the bolt 2415 is fixed to the waste suction connection section 23, and the other end is connected to the waste discharge connection section 13 by screwing it with the nut 2416. The bolt 2415 + nut 2416 method provides a fixed connection between the waste suction connection section 23 and the waste discharge connection section 13.

[0232] Of course, the connection hole 2411 may not be provided in the waste suction connection part 23, and the connection hole 2411 may be provided in the waste discharge connection part 13. Alternatively, connection holes 2411 may be provided in both the waste suction connection part 23 and the waste discharge connection part 13, and the bolt 2415 may be passed through each of the two connection holes 2411 and fastened by fixing nuts 2416 to both ends.

[0233] In one exemplary embodiment, as shown in Figure 57, the waste suction connection section 23 is provided with a receiving cavity 241, which includes a restricting groove 2412 and a connecting hole 2411. The restricting groove 2412 is for accommodating the head of a bolt 2415, and the connecting hole 2411 communicates with the restricting groove 2412 and allows the bolt 2415 to pass through.

[0234] The head of the bolt 2415 is located in the limiting groove 2412, and the threaded portion of the bolt 2415 extends through the connection hole 2411 to the waste discharge connection part 13, and contacts the waste discharge connection part 13 via the nut 2416.

[0235] The dimensions of the connection hole 2411 are smaller than the dimensions of the restricting groove 2412, so that the head located in the restricting groove 2412 does not come out of the connection hole 2411.

[0236] In actual applications, the mounting method of bolt 2415 may be adjusted. For example, bolt 2415 may be mounted in reverse, nut 2416 may be placed inside the housing cavity 241, the head of bolt 2415 may be positioned towards the waste discharge connection 13, and the threaded portion of bolt 2415 may pass through the connection hole 2411 and connect to nut 2416 in the limiting groove 2412.

[0237] In one exemplary embodiment, as shown in Figure 57, the housing cavity 241 is provided with a radial opening 2413, which is configured such that a bolt 2415 enters the housing cavity 241 along the radial direction of the sewage suction connection 23 and the bolt 2415 is tightened into the housing cavity 241. Alternatively, the bolt 2415 is embedded in the sewage suction connection 23, forming an integrated structure with the sewage suction connection 23.

[0238] A radial opening 2413 is provided in the housing cavity 241, and the bolt 2415 is attached to the housing cavity 241 along the radial direction, contributing to the operator's operation during the toilet installation process. The head of the bolt 2415 and the housing cavity 241 may be a restrain fit, so that the bolt 2415 does not fall out after the head is attached to the housing cavity 241, and the nut 2416 can be easily screwed onto the other end of the bolt 2415, making it easy to handle.

[0239] Of course, it is not necessary to install a radial opening 2413 in the containment cavity 241. In the manufacturing process of the waste discharge box 21, the bolt 2415 can be directly embedded in a predetermined position in the waste discharge box 21. In other words, the bolt 2415 and the waste suction connection part 23 can be integrally molded. The integrated structure of the bolt 2415 and the waste suction connection part 23 is advantageous for improving assembly efficiency.

[0240] In one exemplary embodiment, the threaded portion of the bolt 2415 is located radially outward of the waste discharge connection 13. The waste discharge connection 13 includes a second annular flange 132, the end of which is closer to the waste discharge box 21 abuts against the waste suction connection 23. A nut 2416 is located on the side of the second annular flange 132 away from the waste discharge box 21 and is screwed onto the threaded portion of the bolt 2415 to clamp the waste suction connection 23 and the waste discharge connection 13 together with a fastener 2414.

[0241] The second annular flange 132 may be an annular projection structure installed on the waste discharge connection 13 and protruding radially. The second annular flange 132 is located at the end of the waste discharge connection 13 and close to the waste suction connection 23, thereby shortening the distance to the waste suction connection 23 and further shortening the length of the bolt 2415.

[0242] The threaded portion (threaded part) of the bolt 2415 is located radially outside the dirt discharge connection part 13. In other words, no structures such as holes or grooves for mating with the bolt 2415 are provided in the dirt discharge connection part 13. The threaded part of the bolt 2415 protrudes from the dirt discharge connection part 13 for connecting with the nut 2416. That is, the threaded part of the bolt 2415 may exist in the connection hole 2411. In actual application, it is common to integrally form the toilet seat body 1 with ceramic. By positioning the threaded part of the bolt 2415 radially outside the dirt discharge connection part 13, operations such as drilling holes in the toilet seat body 1 become unnecessary, which does not affect the strength of the toilet seat body 1 and can simplify the process.

[0243] The nut 2416 is located on the side away from the dirt discharge box 21 of the second annular flange 132 of the dirt discharge connection part 13. The nut 241 is screwed onto the bolt 2415, and the nut 2416 abuts against the second annular flange 132. One end of the head of the bolt 2415 abuts against or is fixedly connected to the dirt suction connection part 23. By screwing and tightening the nut 2416 onto the bolt 2415, the dirt discharge connection part 13 and the dirt suction connection part 23 are clamped and fixed.

[0244] In one exemplary embodiment, as shown in FIG. 60, the nut 2416 abuts against one end away from the dirt discharge box 21 of the second annular flange 132. Alternatively, the fastener 2414 further includes a washer 2417 located between the nut 2416 and the dirt discharge connection part 13. The washer 2417 is fitted onto the bolt 2415 and abuts against one end away from the dirt discharge box 21 of the second annular flange 132, and the diameter of the washer 2417 is larger than the diameter of the nut 2416.

[0245] In the dirt discharge connection part 13, it can directly abut against the second annular flange 132 in the manner of the nut 2416, and the dirt discharge connection part 13 and the dirt suction connection part 23 can be clamped and fixed, with a simple structure and fewer parts.

[0246] Alternatively, a washer 2417 may be added between the nut 2416 and the waste discharge connection part 13. The diameter of the washer 2417 is larger than the diameter of the nut 2416, increasing the contact area of ​​the washer 2417 with the second annular flange 132, thereby increasing the reliability of the washer 2417 contacting the second annular flange 132, preventing detachment, and ensuring that the waste discharge connection part 13 and the waste suction connection part 23 are securely clamped and fixed.

[0247] In one exemplary embodiment, the waste discharge connection 13 is provided with a connection hole 2411, and the waste suction connection 23 is provided with a threaded hole. A fastener 2414 includes a screw that passes through the connection hole 2411 and screws into the threaded hole (not shown).

[0248] In addition to the above-described configuration in which "the fastener 2414 includes a bolt 2415 and a nut 2416," the fastener 2414 may take other forms. For example, the fastener 2414 may include a screw, with a connection hole 2411 (optical hole) provided in the waste discharge connection part 13, one end of the screw head positioned away from the waste suction connection part 23 of the waste discharge connection part 13, and the other end of the screw being screwed through the connection hole 2411 into the screw hole of the waste suction connection part 23, thereby connecting the toilet seat body 1 and the waste discharge box 21 through the screw and screw hole. In other words, the fastener 2414 may be a single screw, which further reduces the number of parts in the toilet device and simplifies the structure of the toilet device.

[0249] In actual applications, the threaded holes in the waste suction connection section 23 may be vias or blind holes.

[0250] In one exemplary embodiment, as shown in Figure 60, the toilet system further includes a sealing component 4 provided between the waste suction connection 23 and the waste discharge connection 13.

[0251] By interposing a sealing component 4 between the waste suction connection 23 and the waste discharge connection 13, and combining this with the clamping force of the fastener 2414, the sealing performance between the waste suction connection 23 and the waste discharge connection 13 can be further improved, ensuring that phenomena such as water leakage and odor do not occur at the connection point between the two.

[0252] The sealing component 4 can serve as a static seal and may be made of rubber, for example.

[0253] In one exemplary embodiment, a first mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and the seal component 4 is attached to the first mounting groove and abuts against the axial end face of the waste suction connection portion 23 and the axial end face of the waste discharge connection portion 13 to form an end face seal. and / or, the waste suction connection portion 23 is fitted to the outside of the waste discharge connection portion 13, and a second mounting groove is provided in at least one of the waste suction connection portion 23 and the waste discharge connection portion 13, and the seal component 4 is attached to the second mounting groove and abuts against the radial inner end of the waste suction connection portion 23 and the radial outer end of the waste discharge connection portion 13 to form a radial seal.

[0254] The sealing configuration of the sealing component 4 may be an end face seal, a radial seal, or it may have both an end face seal and a radial seal synchronously.

[0255] For the end face seal, a first mounting groove is installed in the waste suction connection part 23, the seal component 4 is mounted in the first mounting groove along the axial direction, and the waste discharge connection part 13 abuts against the seal component 4 in the first mounting groove. After connecting the waste suction connection part 23 and the waste discharge connection part 13, the fastener 2414 can exert a certain pressing effect on the seal component 4. In other words, the fastener 2414 can compress the seal component 4 to enhance its sealing effect.

[0256] Regarding the radial seal, a second mounting groove is installed in the waste suction connection part 23, and the seal part 4 is positioned radially. in the second mounting grooveThe waste discharge connection portion 13 is attached to the second mounting groove, and the waste discharge connection portion 13 abuts against the seal component 4. In the radial direction, the space between the waste suction connection portion 23 and the waste discharge connection portion 13 may be a gap fit, and the seal component 4 can be fitted into the second mounting groove by interlocking. In other words, the seal component 4 is pressed by the inner wall of the waste suction connection portion 23 and the outer wall of the waste discharge connection portion 13, compressing the seal component 4 and enhancing its sealing effect.

[0257] In one exemplary embodiment, a rotation prevention structure is provided between the waste suction connection 23 and the waste discharge connection 13 to restrict the rotation of the waste discharge box 21 relative to the toilet seat body 1.

[0258] A rotation prevention structure is installed between the waste suction connection part 23 and the waste discharge connection part 13 to prevent the waste discharge box 21 from rotating.

[0259] The clamp 2414 clamps and fixes the waste discharge connection 13 and the waste suction connection 23, restricting both in the axial direction and preventing the waste discharge box 21 from detaching rearward along the axial direction relative to the toilet seat body 1. However, when the waste discharge box 21 is subjected to a circumferential force, the clamp 2414 cannot provide circumferential restriction. By providing a rotation prevention structure between the waste suction connection 23 and the waste discharge connection 13, it is possible to prevent the waste discharge box 21 from rotating relative to the toilet seat body 1 due to a circumferential force, and furthermore, to completely fix and restrict the waste discharge box 21, thereby preventing it from moving or rotating during operation and ensuring the reliable operation of the toilet device.

[0260] In one exemplary embodiment, as shown in Figures 58 and 62, the waste suction connection portion 23 is fitted to the outside of the second annular flange 132, the outer wall of the waste discharge connection portion 13 is provided with a non-circular first rotation prevention wall surface 261, and the waste suction connection portion 23 is provided with a second rotation prevention wall surface 264 that matches the first rotation prevention wall surface 261, and the rotation prevention structure comprises the first rotation prevention wall surface 261 and the second rotation prevention wall surface 264.

[0261] The dirt suction connection part 23 is fitted outside the second annular flange 132, plays a certain guiding role, and can accurately align the dirt suction connection part 23 and the dirt discharge connection part 13.

[0262] On the outer wall of the dirt discharge connection part 13, a non-circular first anti-rotation wall surface 261 is provided. On the inner wall of the dirt suction connection part 23, a second anti-rotation wall surface 264 is provided. The first anti-rotation wall surface 261 and the second anti-rotation wall surface 264 are non-circular wall surfaces of the same shape, which prevent the rotation of the dirt discharge box 21 relative to the toilet seat body 1.

[0263] The dirt suction connection part 23 is fitted outside the second annular flange 132, and the first anti-rotation wall surface 261 is brought into close contact with the second anti-rotation wall surface 264 along the radial direction. Since both the first anti-rotation wall surface 261 and the second anti-rotation wall surface 264 are non-circular, it is possible to avoid the relative rotation between the first anti-rotation wall surface 261 and the second anti-rotation wall surface 264, that is, the rotation of the dirt discharge mechanism 2 relative to the toilet seat body 1.

[0264] For example, the first anti-rotation wall surface 261 and the second anti-rotation wall surface 264 may be irregular annular shapes formed by an arc + a straight line, and the first anti-rotation wall surface 261 and the second anti-rotation wall surface 264 can together play a role in restricting the circumferential direction. Of course, the first anti-rotation wall surface 261 and the second anti-rotation wall surface 264 may be other shapes such as an ellipse, a polygon, etc. that can prevent relative rotation.

[0265] The first anti-rotation wall surface 261 and the second anti-rotation wall surface 264 together form an anti-rotation structure.

[0266] In addition to the forms of the above first anti-rotation wall surface 261 and second anti-rotation wall surface 264, the anti-rotation structure may further adopt other forms. For example, a limiting block is provided on the dirt discharge connection part 13, and a corresponding receiving groove 233 is provided on the dirt suction connection part 23, and the limiting block and the receiving groove 233 that match each other are used as the anti-rotation structure.

[0267] Furthermore, the waste discharge pipe 22 can be rotatably mounted inside the waste discharge box 21, and an oil seal can be installed at the rotatable connection to form a dynamic seal, thereby improving the sealing performance of the connection.

[0268] The toilet system may also be equipped with a shifter 51, which is located below the waste discharge mechanism 2, the inlet of the shifter 51 is connected to the outlet of the waste discharge box 21, and the outlet of the shifter 51 is connected to the outside In the waste discharge pipe They are connected. A rim spout 52 is attached to the toilet seat body 1, and the rim spout 52 is fixed to the toilet seat body 1 to draw water for flushing the toilet system.

[0269] As shown in Figures 64 to 74, one embodiment of the present invention provides a toilet device, referring to Figure 2, the toilet device is a toilet seat body 1, Waste Discharge Mechanism 2 It also includes a screw tightening sleeve 26.

[0270] The toilet seat body 1 is provided with a toilet bowl 11 and a waste discharge port 12 that communicates with the toilet bowl 11. A waste discharge connection part 13 is provided on the outer circumference of the waste discharge port 12. The waste discharge connection part 13 is located outside the toilet bowl 11 and is provided with a passage 1323 that communicates with the waste discharge port 12.

[0271] Waste Discharge Mechanism 2 The system includes a waste discharge box 21 and a waste discharge pipe 22 located inside the waste discharge box 21. The waste discharge box 21 is provided with a waste intake port 211 that communicates with the passage 1323. A waste intake connection part 23 is provided on the outer circumference of the waste intake port 211. The waste intake connection part 23 protrudes from the outer wall of the waste discharge box 21 and is fitted to the outside of the waste discharge connection part 13. The waste discharge pipe 22 communicates with the waste intake port 211 and is rotatable relative to the waste discharge box 21.

[0272] The screw-tightening sleeve 26 is fitted to the outside of the waste suction connection part 23 and, by screwing it into the waste suction connection part 23, the waste suction connection part 23 is fastened to the waste discharge connection part 13, thereby fixing the waste discharge box 21 to the toilet seat body 1.

[0273] The toilet device according to the embodiment of the present application is a toilet seat body 1, Waste Discharge Mechanism 2and a screw tightening sleeve 26 is provided. The toilet seat body 1 is provided with a toilet bowl 11 and a waste outlet 12, and waste in the toilet bowl 11 is discharged from the waste outlet 12. The waste outlet 12 has, Waste Discharge Mechanism 2 A waste discharge connection part 13 is provided for connecting to it. Waste Discharge Mechanism 2 The system includes a waste discharge box 21 and a waste discharge pipe 22. The waste discharge pipe 22 can communicate with the waste discharge port 12 via a passage 1323 in the waste discharge connection section 13 and a waste intake port 211 of the waste discharge box 21, and a reverse waste discharge function is realized by rotation. The waste discharge box 21 serves to house the waste discharge pipe 22 and realizes an indirect connection between the waste discharge pipe 22 and the waste discharge port 12.

[0274] A waste suction connection part 23 is provided in the waste discharge box 21, and a male thread that fits the screw tightening sleeve 26 is provided on the outer wall of the waste suction connection part 23. During the assembly process, the waste suction connection part 23 may first be fitted onto the outside of the waste discharge connection part 13 to form an axial hole fitting structure. Then, the screw tightening sleeve 26 is screwed onto the outside of the waste suction connection part 23, and the screw tightening sleeve 26 exerts an action that presses the waste suction connection part 23 radially inward, preventing the waste suction connection part 23 from detaching from the waste discharge connection part 13 in the reverse direction, and securely fixing it to the waste discharge connection part 13, thereby achieving a fixed connection between the waste discharge box 21 and the toilet seat body 1.

[0275] Compared to adhesive fastening, the screw-fastening sleeve 26 is less prone to deterioration over time. By adopting the screw-fastening sleeve 26 to achieve a fixed connection between the waste discharge box 21 and the toilet seat body 1, the connection strength is high and the fixation is secure. Furthermore, since the screw-fastening sleeve 26 is relatively easy to remove, this configuration also contributes to toilet maintenance and replacement of internal parts during subsequent use.

[0276] In one example, the waste discharge connection part 13 and the waste suction connection part 23 can be short tubular structures. As shown in Figure 64, the waste discharge port 12 is located at the lower rear of the toilet bowl 11, and the waste discharge connection part 13 extends outward from the waste discharge port 12. Toilet seat body 1It protrudes from the rear. The direction of protrusion of the waste discharge connection part 13 may be horizontal or inclined downward, so that the internal passage 1323 extends horizontally toward the rear or inclined toward the rear, thereby preventing backflow of waste and allowing for smooth discharge of waste.

[0277] The waste discharge box 21 and waste discharge pipe 22 may be made of plastic, and can be easily processed into any desired shape as needed. The male thread of the waste suction connection part 23 of the waste discharge box 21 can also be easily processed and formed. The toilet seat body 1 may be made of ceramic, hard plastic, or other material.

[0278] In one example, as shown in Figures 64 to 67, the waste discharge box 21 is provided with a waste outlet 253, which can communicate with an external waste discharge pipe (for example, a floor waste discharge pipe) via a shifter 51, and the waste discharged from the waste discharge pipe 22 is discharged into the external waste discharge pipe.

[0279] In one exemplary embodiment, as shown in Figures 65, 67, 71, and 72, the waste discharge connection 13 includes a tubular portion 1322 and a second annular flange 132 provided on the outer wall of the tubular portion 1322. As shown in Figure 72, a passage 1323 is provided inside the tubular portion 1322. As shown in Figures 68, 69, 71, and 73, a locking projection 2111 is provided on the inner wall of the waste suction connection 23. As shown in Figure 71, the locking projection 2111 engages with the second annular flange 132, restricting the waste suction connection 23 from moving away from the toilet bowl 11.

[0280] During the process of fitting the waste suction connection part 23 to the outside of the waste discharge connection part 13, when the locking projection 2111 overcomes the second annular flange 132 and catches on the second annular flange 132, it indicates that the waste suction connection part 23 has been attached to the shaft, and at this point the screw tightening sleeve 26 can be screwed in. On the other hand, the restrictive fitting between the locking projection 2111 and the second annular flange 132 makes it difficult for the waste suction connection part 23 to come off the waste discharge connection part 13 in the reverse direction, improving the axial positional stability of the waste discharge box 21.

[0281] Therefore, the fitting of the locking projection 2111 and the second annular flange 132 can exert a positioning and limiting effect on the assembly of the waste discharge box 21 and the toilet seat body 1, thereby improving the assembly efficiency of the toilet device and the assembled Waste Discharge Mechanism 2 This is advantageous for improving stability.

[0282] In one example, the locking projection 2111 is provided on the inner wall of the waste suction connection part 23 and is integrally molded with the inner wall of the waste suction connection part 23.

[0283] The projection of the locking projection 2111 on the vertical cross-section of the waste suction connection portion 23 may be a right triangle, rectangle, or right trapezoid, and the end face away from the toilet bowl 11 is perpendicular to the axis of the waste suction connection portion 23 and is set to abut the end face of the second annular flange 132 that is closer to the toilet bowl 11.

[0284] In one exemplary embodiment, as shown in Figures 68 and 69, the locking projection 2111 is provided at one end of the waste suction connection 23 closest to the toilet bowl 11. As shown in Figure 71, the tubular portion 1322, the second annular flange 132, and the toilet seat body 1 surround each other to form a locking groove 1324 for accommodating the locking projection 2111.

[0285] This makes it possible to shorten the axial length of the waste suction connection part 23, and consequently, Waste Discharge Mechanism 2 This allows for a reduction in the installation space required and a reduction in the axial length of the toilet unit.

[0286] In one example, a locking groove 1324 is formed between the upper part of the tubular section 1322, the upper part of the second annular flange 132, and the toilet seat body 1, and the bottom of the tubular section 1322 is smoothly connected to the toilet seat body 1. There are multiple locking protrusions 2111, and as shown in Figures 68, 69, and 73, the multiple locking protrusions 2111 are installed at intervals along the circumferential direction of the waste suction connection section 23. Some of the locking protrusions 2111 are located within the locking groove 1324.

[0287] As shown in Figure 65, at least two (for example, two, three, four, five, six, seven, eight, etc.) locking projections 2111 are installed at intervals along the circumferential direction of the waste suction connection part 23, all of which are the same size, and each locking projection 2111 is subjected to the same force.

[0288] In one exemplary embodiment, as shown in Figures 68, 69, and 73, the waste suction connection 23 is provided with at least one notch 2112, the notch 2112 being for the waste suction connection 23 to expand and deform during the process of fitting into the waste discharge connection 13.

[0289] The waste suction connection part 23 and the waste discharge connection part 13 form an axial hole fitting structure and are secured radially by a screw tightening sleeve 26. As a result, the inner diameter of the waste suction connection part 23 and the outer diameter of the waste discharge connection part 13 are very close, making assembly of the waste suction connection part 23 and the waste discharge connection part 13 difficult. Furthermore, the toilet seat body 1 is usually made of ceramic, and due to the limitations of the ceramic manufacturing process, the waste discharge connection part 13 has the disadvantage of not being highly precise, making assembly of the waste suction connection part 23 and the waste discharge connection part 13 even more difficult.

[0290] Therefore, by creating at least one notch 2112 in the waste suction connection part 23, the waste suction connection part 23 expands and deforms during assembly, which is equivalent to the waste suction connection part 23 bulging and becoming thicker during assembly. This reduces the difficulty of fitting the waste suction connection part 23 into the waste discharge connection part 13, and consequently improves assembly efficiency. On the other hand, the bulging portion of the waste suction connection part 23 is tightened during the subsequent tightening process of the screw tightening sleeve 26, ensuring that the waste suction connection part 23 does not tear and affect the reliability of the waste discharge box 21.

[0291] In particular, in the configuration in which a second annular flange 132 for engaging the waste discharge connection 13 is further provided on the inner wall of the waste suction connection 23, the installation of the cut 2112 reduces the difficulty of the locking projection 2111 overcoming the second annular flange 132, reduces the degree of interference between the locking projection 2111 and the second annular flange 132, further reduces the difficulty of installation and improves installation efficiency.

[0292] In one exemplary embodiment, as shown in Figures 68 and 69, the cut 2112 extends along the axial direction of the waste suction connection 23 and penetrates one end of the waste suction connection 23 that is closer to the toilet bowl 11.

[0293] In this way, the end of the waste suction connection 23 closest to the toilet bowl 11 can be made thicker during assembly, thereby forming a flared structure for the waste suction connection 23. This further reduces the difficulty of fitting the waste suction connection 23 into the waste discharge connection 13, improving assembly efficiency. It is also convenient for processing and shaping the cut end 2112.

[0294] In one exemplary embodiment, as shown in Figures 62 and 69, the length of the cut 2112 is shorter than the axial length of the waste suction connection 23.

[0295] Thus, the portion of the waste suction connection 23 closest to the toilet bowl 11 can be expanded and deformed, which is convenient for smooth and quick fitting of the waste suction connection 23 to the waste discharge connection 13. On the other hand, the portion of the waste suction connection 23 away from the toilet bowl 11 cannot be expanded and deformed, and this portion is complete in the circumferential direction. Because this portion is close to the waste suction port 211, it is advantageous in preventing waste and odors from leaking out of this portion.

[0296] As shown in Figures 68 and 69, the cut 2112 extends rearward along the axial direction of the waste suction connection 23 from one end (i.e., the front end) away from the waste suction port 211 of the waste suction connection 23. Along the radial direction of the waste suction connection 23, the cut 2112 penetrates the inner and outer walls of the waste suction connection 23.

[0297] In one example, as shown in Figures 68, 69, and 73, there are multiple cuts 2112, and these multiple cuts 2112 are spaced apart along the circumferential direction of the waste suction connection part 23, and are, for example, uniformly spaced.

[0298] In the configuration in which the locking projection 2111 is provided on the inner wall of the waste suction connection part 23, the cut 2112 and the locking projection 2111 may be offset from each other, as shown in Figure 73.

[0299] For example, the number of cuts 2112 in the waste suction connection section 23 may be two, three, four, five, six, seven, eight, etc. The width and depth of all cuts 2112 may also be set to be the same.

[0300] The multiple cuts 2112 are advantageous for increasing the degree of expansion of the waste suction connection 23, further reducing the difficulty of installation. On the other hand, they are advantageous for distributing the force that the waste suction connection 23 receives due to the expansion deformation, making the force that the waste suction connection 23 receives more even, and reducing the risk of the waste suction connection 23 expanding excessively and causing tearing defects.

[0301] In one example, as shown in Figures 68 and 69, the length of the cut 2112 is longer than the width of the locking projection 2111 that runs along the axial direction of the waste suction connection 23.

[0302] In one exemplary embodiment, as shown in Figure 71, the axial length of the screw-fastening sleeve 26 is smaller than the axial length of the sewage suction connection 23.

[0303] In this way, the screw-tightening sleeve 26 can be pre-fitted onto the waste suction connection part 23 and screwed into the portion of the waste suction connection part 23 that is away from the toilet bowl 11. The waste suction connection part 23 can be fitted onto the waste discharge connection part 13 with the screw-tightening sleeve 26 attached. With the waste suction connection part 23 fitted, the screw-tightening sleeve 26 is screwed in the reverse direction to rotate the screw-tightening sleeve 26 to the portion of the waste suction connection part 23 closer to the toilet bowl 11, and this portion is pressed tightly in the radial direction to secure the fastened connection between the waste suction connection part 23 and the waste discharge connection part 13. This is also advantageous in avoiding the loss of the screw-tightening sleeve 26.

[0304] In the configuration in which a cut 2112 is further provided in the waste suction connection part 23, by fitting the screw tightening sleeve 26 onto the waste suction connection part 23, it is possible to prevent the cut 2112 from extending backward and tearing the waste suction connection part 23 when it is expanded, thereby improving the reliability of the waste suction connection part 23.

[0305] The screwing direction of the screw fastening sleeve 26 is not limited. For example, the screw fastening sleeve 26 may be screwed counterclockwise to the rear of the waste suction connection part 23. Once the waste suction connection part 23 is fitted, the screw fastening sleeve 26 may be screwed clockwise to the front of the waste suction connection part 23.

[0306] In one exemplary embodiment, as shown in Figures 70 and 71, one end of the screw-fastening sleeve 26 closest to the toilet bowl 11 abuts against the toilet seat body 1.

[0307] Thus, during the assembly process, when the screw tightening sleeve 26 is screwed in until it contacts the toilet seat body 1, the screwing process may be stopped. In this way, the toilet seat body 1 plays a positioning role in the assembly of the screw tightening sleeve 26, and excessive screwing of the screw tightening sleeve 26 can be avoided.

[0308] In one exemplary embodiment, an indicator mark is provided on the outer wall of the screw fastening sleeve 26.

[0309] In this way, it becomes easier for the installer to screw the screw tightening sleeve 26 in the correct direction based on the indicator mark, and the process of trying to install the screw tightening sleeve 26 by checking the front and back sides is avoided, which is advantageous in improving the assembly efficiency of the toilet equipment.

[0310] In one example, as shown in Figures 67 and 71, the indicator mark is a protruding edge 260 provided at the end of the screw tightening sleeve 26.

[0311] Thus, the convex edge 260 can serve as an indicator mark, is advantageous in increasing the rotational moment of the screw fastening sleeve 26, is advantageous in reducing the force applied when screwing in the screw fastening sleeve 26, further reduces the difficulty of installation, and improves assembly efficiency.

[0312] Of course, the directional sign is not limited to this format; it may also contain directional arrows, directional text, or other similar content.

[0313] In one exemplary embodiment, the toilet device further comprises a first sealing component (not shown), wherein at least one of the waste suction connection portion 23 and the waste discharge connection portion 13 is provided with a first mounting groove (not shown), and the first sealing component is attached to the first mounting groove and contacts the axial end face of the waste suction connection portion 23 and the axial end face of the waste discharge connection portion 13 to form an end seal.

[0314] The first sealing component can achieve axial sealing between the waste suction connection 23 and the waste discharge connection 13, which is advantageous in preventing the leakage of waste and odors to the outside from between the waste suction connection 23 and the waste discharge connection 13, and is advantageous in improving the reliability of the toilet system and the user experience.

[0315] In one exemplary embodiment, the toilet device further comprises a second sealing component (not shown), wherein at least one of the waste suction connection 23 and the waste discharge connection 13 is provided with a second mounting groove (not shown), and the second sealing component is attached to the second mounting groove and abuts against the radial inner end of the waste suction connection 23 and the radial outer end of the waste discharge connection 13 to form a radial seal.

[0316] The second sealing component can achieve a radial seal between the waste suction connection 23 and the waste discharge connection 13, which is advantageous in preventing waste and odors from leaking to the outside from between the waste suction connection 23 and the waste discharge connection 13, and is advantageous in improving the reliability of the toilet system and the user experience.

[0317] In one exemplary embodiment, as shown in Figure 71, a seal groove 1325 is provided in the waste discharge connection section 13, and a seal component 4 is provided in the seal groove 1325.

[0318] A stopper projection 2114 is provided on the inner wall of the waste suction connection part 23, and the stopper projection 2114 abuts against and aligns with one end of the waste discharge connection part 13 that is away from the toilet bowl 11.

[0319] The outer wall of the sealing component 4 abuts against the inner wall of the waste suction connection portion 23, and the axial end face of the sealing component 4 away from the toilet bowl 11 abuts against the stopper projection 2114.

[0320] In this embodiment, the fitting of the stopper projection 2114 with the waste discharge connection part 13 allows for the positioning of the waste discharge box 21 during assembly, thereby preventing the waste discharge box 21 from being excessively pressed against the waste suction connection part 23 along the axial direction.

[0321] Since the inner wall of the sealing component 4 abuts against the outer wall of the waste discharge connection portion 13, and the outer wall of the sealing component 4 abuts against the inner wall of the waste suction connection portion 23, a radial seal can be achieved between the waste suction connection portion 23 and the waste discharge connection portion 13. Since the axial end face of the sealing component 4 closest to the toilet bowl 11 (i.e., the front end face) contacts the waste discharge connection portion 13, and the axial end face away from the toilet bowl 11 (i.e., the rear end face) abuts against the stopper projection 2114, an axial seal can be achieved between the waste suction connection portion 23 and the waste discharge connection portion 13.

[0322] In this way, a single sealing component 4 can achieve both axial and radial sealing between the waste suction connection 23 and the waste discharge connection 13, effectively improving the sealing reliability between the waste discharge box 21 and the toilet seat body 1, and the simple structure is advantageous for cost reduction and simplification of the installation process.

[0323] In one example, the portion of the outer wall of the tubular section 1322 located behind the second annular flange 132 surrounds the second annular flange 132 to form the seal groove 1325. Therefore, the rear end of the seal groove 1325 is installed open, and the radial outer end is also installed open. The overall structure of the waste discharge connection section 13 is relatively simple.

[0324] In one example, as shown in Figures 70 and 71, a sealing component 4 is provided in the sealing groove 1325. Since the sealing component 4 is elastic, in order to achieve a tighter seal, the radial thickness of the sealing component 4 when not tightly pressed is set to be greater than the radial thickness of the second annular flange 132. In this way, after the fitting of the waste suction connection 23 and the waste discharge connection 13 is completed, the sealing component 4 applies pressure to the waste suction connection 23 and the waste discharge connection 13 in a synchronous manner along the radial direction due to its own elastic force, achieving a good radial sealing effect between the waste suction connection 23 and the waste discharge connection 13.

[0325] Similarly, the axial width of the seal component 4, which is not tightly pressed, is set to be greater than the distance from one end of the second annular flange 132 away from the toilet bowl 11 to the stopper projection 2114. In this way, after the fitting of the waste suction connection 23 and the waste discharge connection 13 is completed, the press-fitting of the second annular flange 132 and the stopper projection 2114 causes the seal component 4 to apply pressure to the second annular flange 132 and the stopper projection 2114 in the axial direction, achieving a good axial sealing effect between the waste suction connection 23 and the waste discharge connection 13.

[0326] Furthermore, in the embodiment of this application, each of the above-mentioned sealing components (first sealing component, second sealing component, sealing component) is allowed to maintain a large amount of compression, thereby reducing sealing defects of the ceramic toilet seat body 1 due to large dimensional fluctuations.

[0327] In one exemplary embodiment, a rotation prevention structure is provided between the waste suction connection 23 and the waste discharge connection 13 to restrict the rotation of the waste discharge box 21 relative to the toilet seat body 1.

[0328] If the number of rotations of the waste discharge pipe 22 and waste discharge increases, the waste suction connection part 23 of the waste discharge box 21 may rotate circumferentially relative to the waste discharge connection part 13, causing the waste discharge box 21 to shift from its original upright position and affecting waste discharge performance. Therefore, by providing a rotation prevention structure between the waste suction connection part 23 and the waste discharge connection part 13, the rotation of the waste discharge box 21 relative to the toilet seat body 1 is limited, and the positional stability of the waste discharge box 21 and the waste discharge pipe 22 is further improved. Waste Discharge Mechanism 2 This ensures the reliability of its use.

[0329] In one exemplary embodiment, the anti-rotation structure comprises an anti-rotation projection 92 (as shown in Figure 73) and an anti-rotation recess 91 (as shown in Figure 72), with the anti-rotation recess 91 provided on one of the waste discharge connection portion 13 and the waste suction connection portion 23, and the anti-rotation projection 92 provided on the other, and the anti-rotation recess 91 and the anti-rotation projection 92 interlock to restrict the rotation of the waste suction connection portion 23 relative to the waste discharge connection portion 13. This embodiment has a simple structure and is easy to process and mold.

[0330] In one example, as shown in Figure 72, a rotation-preventing recess 91 is provided at the end of the waste discharge connection 13 that is away from the toilet bowl 11. As shown in Figure 73, a rotation-preventing projection 92 is provided at the corresponding position of the waste suction connection 23. After the waste suction connection 23 is fitted into the waste discharge connection 13 (at this time, the waste discharge box 21 is in an upright position), the rotation-preventing projection 92 is inserted into the rotation-preventing recess 91, and the rotation-preventing projection 92 conforms to the shape and dimensions of the rotation-preventing recess 91, thereby preventing the waste discharge box 21 from rotating.

[0331] The number of rotation-preventing recesses 91 may be one or multiple. The number of rotation-preventing protrusions 92 may be equal to the number of rotation-preventing recesses 91 and correspond to them in a one-to-one relationship.

[0332] In other embodiments, the rotation-preventing recess 91 may be located on the waste suction connection portion 23, and the rotation-preventing projection 92 may be provided correspondingly on the waste discharge connection portion 13.

[0333] Of course, the anti-rotation structure is not limited to the above form; if the waste suction connection part 23 and the waste discharge connection part 13 form a non-circular fitting structure in the circumferential direction, it can also serve to prevent rotation.

[0334] In one exemplary embodiment, as shown in Figures 68, 69 and 71, Waste Discharge Mechanism 2The system further includes a waste discharge pipe 22 located inside the waste discharge box 21, the waste discharge pipe 22 communicating with the waste intake port 211 and rotatable relative to the waste discharge box 21. Inside the waste discharge box 21, there is a slot 252 whose opening faces the waste intake port, and one end of the waste discharge pipe 22 is rotatably inserted into the slot 252.

[0335] Slot 252 is further provided with a third sealing component 2115 for sealing the waste discharge pipe 22 and the waste discharge box 21. The third sealing component 2115 may be an oil seal.

[0336] In this way, the waste discharge pipe 22 forms a dynamic seal with the waste discharge box 21 by the oil seal, and the gap that is created between the waste discharge pipe 22 and the waste discharge box 21 during the rotation of the waste discharge pipe 22 relative to the waste discharge box 21 is continuously sealed, preventing water leakage and odor problems.

[0337] A connecting projection 251 is provided inside the waste discharge box 21, and the connecting projection 251 surrounds the inner wall of the waste discharge box 21 to form a slot 252.

[0338] Of course, the third seal component 2115 may adopt other structural forms.

[0339] In this embodiment, both the waste discharge pipe 22 and the waste discharge box 21 are made of plastic. In other embodiments, other materials may be selected for the waste discharge pipe 22 and the waste discharge box 21.

[0340] As shown in Figures 68, 69, and 71, the slot 252 is located outside the circumferential edge of the waste intake port 211, and the depth and width of the slot 252 are suitable for receiving one end of the waste discharge pipe 22, into which the waste discharge pipe 22 is partially inserted. The waste discharge pipe 22 communicates with the waste outlet 12 of the toilet bowl 11 via the internal passage of the waste intake port 211 and the connecting projection 251. The waste discharge pipe 22 is located inside the waste discharge box 21. When waste is discharged, the waste in the toilet bowl 11 enters the waste discharge pipe 22, and as shown in Figure 74, as the waste discharge pipe 22 rotates downward, gravity causes it to be discharged from the waste discharge pipe 22 and discharged through the waste outlet 253 of the waste discharge box 21 and the shifter 51 to the floor waste discharge piping.
