Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Conventional toilet bodies are typically ceramic pieces. Due to the limitation of the manufacturing process, the ceramic part often has the defect of low precision in production. In addition, the ceramic piece is not easy to punch and process threads, so that the fastening piece is difficult to install, and the toilet body is difficult to be connected with the sewage discharge part through the fastening piece. On the other hand, the abutment of the toilet body and the waste discharge member needs to ensure good sealing to prevent leakage of dirt or odor from the abutment.

Therefore, in the conventional design, when the closestool body is butted with a sewage discharge part (such as a fixed sewage discharge pipeline and a fixed sewage discharge box), the closestool body is bonded and fixed by adopting sealant, so that the butted part is sealed while the fixed connection is realized. However, the sealant is easy to age and fail after a long time, so that the connection mode has the problems of low connection strength and easy connection failure.

The soil exhaust apparatus 1 includes a soil exhaust box 10 and a soil exhaust pipe 13 located inside the soil exhaust box 10. The waste box 10 is provided with a waste inlet 12 communicating with the passage 234. A dirt inlet connecting part 11 is arranged on the periphery of the dirt inlet 12. The sewage inlet connecting part 11 is convexly arranged on the outer wall of the sewage discharging box 10 and is sleeved outside the sewage discharging connecting part 23. The sewage discharging pipe 13 is communicated with the sewage inlet 12 and can rotate relative to the sewage discharging box 10.

The screw fastening sleeve 3 is sleeved outside the sewage inlet connecting part 11 and is in threaded connection with the sewage inlet connecting part 11, so that the sewage inlet connecting part 11 is fastened on the sewage discharge connecting part 23, and the sewage discharge box 10 is fixed on the toilet body 2.

The closestool system that this application embodiment provided includes closestool body 2, waste fitting discharging 1 and screw fastening cover 3. The toilet body 2 is provided with a bowl 21 and a drain outlet 211, and the sewage in the bowl 21 is discharged through the drain outlet 211. The sewage outlet 211 is provided with a sewage connection part 23 for connecting the sewage discharging device 1. The sewage discharging device 1 comprises a sewage discharging box 10 and a sewage discharging pipe 13, wherein the sewage discharging pipe 13 can be communicated with the sewage discharging port 211 through a channel 234 in the sewage discharging connecting part 23 and a sewage inlet 12 of the sewage discharging box 10, and the overturning sewage discharging function is realized through rotation. The waste box 10 has an accommodation function for the waste pipe 13 and realizes the indirect connection of the waste pipe 13 and the waste outlet 211.

Wherein, the dirty connecting portion 11 is advanced to the corresponding being equipped with of blowdown box 10, advances the lateral wall of dirty connecting portion 11 and is equipped with the external screw thread with 3 looks adaptations of thread tightening sleeve. In the assembling process, the sewage inlet connecting part 11 can be sleeved on the outer side of the sewage discharge connecting part 23 to form a shaft hole matching structure. Then screw up screw thread adapter sleeve 3 in the outside of advancing dirty connecting portion 11, then screw thread adapter sleeve 3 can play radial inward effect of compressing tightly to advancing dirty connecting portion 11, makes and advances dirty connecting portion 11 and tightly fix on blowdown connecting portion 23 and can not reverse break away from blowdown connecting portion 23, realizes the fixed connection of blowdown box 10 and closestool body 2 from this.

Compared with a bonding and fixing mode, the threaded fastening sleeve 3 is not easy to age and lose efficacy, so that the fixed connection between the sewage discharge box 10 and the toilet body 2 is realized by the threaded fastening sleeve 3, the connection strength is high, and the fixation is firm. In addition, the screw fastening sleeve 3 is convenient to disassemble, so that the scheme is convenient for maintenance of the closestool and replacement of internal parts in the subsequent use process.

In one example, the waste connection 23 and the waste inlet connection 11 may be designed as short tubular structures. The soil discharge outlet 211 is located at the lower rear portion of the bowl 21, and the soil discharge connection part 23 protrudes outward from the soil discharge outlet 211 toward the rear portion of the toilet body 21, as shown in fig. 2. The protruding direction of the soil connection part 23 may be horizontal or inclined downward such that the inner channel 234 extends horizontally rearward or inclined rearward, which facilitates smooth discharge of the soil and prevents backflow of the soil.

The pollution discharge box 10 and the pollution discharge pipe 13 can be plastic pieces, so that the pollution discharge box can be conveniently processed into a required shape as required, and the external thread on the pollution discharge connection part 11 of the pollution discharge box 10 can be conveniently processed and formed. The toilet body 2 may be made of ceramic, rigid plastic or other materials.

In one example, the waste box 10 is provided with a waste outlet 16, and the waste outlet 16 may communicate with an external waste pipe (e.g., a floor waste pipe) through the shifter 5, as shown in fig. 2 to 5, thereby discharging the waste discharged from the waste pipe 13 into the external waste pipe.

In an exemplary embodiment, as shown in fig. 3, 5, 9 and 10, the waste connection 23 includes a tubular portion 233 and an annular flange 231 provided on an outer sidewall of the tubular portion 233. The tubular portion 233 is provided with a passage 234, as shown in fig. 10, and as shown in fig. 6, 7, 9 and 11, the inner side wall of the dirt inlet connecting portion 11 is provided with a locking protrusion 111. The catching protrusion 111 catches the annular flange 231, as shown in fig. 9, to restrict the movement of the dirt intake connecting portion 11 in a direction away from the bowl 21.

When the clamping protrusion 111 passes over the annular flange 231 and hooks the annular flange 231 in the process that the dirt inlet connecting part 11 is sleeved outside the dirt discharge connecting part 23, the dirt inlet connecting part 11 is installed on the shaft in place, and the thread fastening sleeve 3 can be screwed on at the moment. And due to the limit fit of the clamping protrusion 111 and the annular flange 231, the sewage inlet connecting part 11 is difficult to reversely separate from the sewage connecting part 23, so that the position stability of the sewage discharging box 10 in the axial direction is improved.

Therefore, the cooperation of the locking protrusion 111 and the annular flange 231 can play a role in positioning and limiting the assembly between the waste box 10 and the toilet body 2, which is not only beneficial to improving the assembly efficiency of the toilet system, but also beneficial to improving the stability of the waste device 1 after the assembly is completed.

In one example, the catching protrusion 111 is formed on an inner sidewall of the dirt intake connecting portion 11 and is integrally formed with the inner sidewall of the dirt intake connecting portion 11.

The projection of the locking protrusion 111 on the longitudinal section of the sewage inlet connection portion 11 may be a right triangle, a rectangle, or a right trapezoid, the end surface away from the toilet bowl 21 is perpendicular to the axis of the sewage inlet connection portion 11, and is disposed to abut against the end surface of the annular flange 231 close to the toilet bowl 21.

In an exemplary embodiment, as shown in fig. 6 and 7, a snap 111 is provided at an end of the dirt intake connection 11 near the urinal 21. The tubular portion 233, the annular flange 231 and the toilet body 2 enclose a catch 24 for receiving the catch 111, as shown in fig. 9.

This is advantageous for shortening the axial length of the sewage inlet connection portion 11, and is further advantageous for reducing the requirement of the sewage discharge apparatus 1 for the installation space, and is advantageous for reducing the axial length of the toilet system.

In one example, the upper portion of the tubular portion 233, the upper portion of the annular flange 231, and the toilet body 2 form a catch 24 therebetween, and the bottom of the tubular portion 233 smoothly meets the toilet body 2. The number of the catching projections 111 is plural, and as shown in fig. 6, 7 and 11, the plural catching projections 111 are provided at intervals in the circumferential direction of the dirt intake connecting portion 11. A portion of the snap projection 111 is located within the snap slot 24.

As shown in fig. 3, the fastening protrusions 111 are arranged at intervals along the circumferential direction of the dirt intake connecting portion 11, the number of the fastening protrusions 111 is at least two (e.g., 2, 3, 4, 5, 6, 7, 8, etc.), and all the fastening protrusions 111 have the same size, so that the force applied to each fastening protrusion 111 is the same.

In an exemplary embodiment, as shown in fig. 6, 7 and 11, the dirt intake connecting portion 11 is provided with at least one slit 112, and the slit 112 allows the dirt intake connecting portion 11 to be expanded and deformed during the process of being nested in the dirt discharge connecting portion 23.

Because advance dirty connecting portion 11 and blowdown connecting portion 23 and will form shaft hole cooperation structure to realize radially locking fixedly through screw fastening sleeve 3, therefore advance the internal diameter of dirty connecting portion 11 and the external diameter of blowdown connecting portion 23 and be very close, lead to advancing the assembly between dirty connecting portion 11 and the blowdown connecting portion 23 comparatively difficult. Moreover, the toilet body 2 is usually a ceramic body, which is limited by the limitation of the ceramic manufacturing process, and the sewage connection part 23 has a defect of low precision, which makes the assembly between the sewage inlet connection part 11 and the sewage connection part 23 more difficult.

Therefore, at least one notch 112 is formed in the sewage inlet connecting portion 11, so that the sewage inlet connecting portion 11 can expand and deform in the assembling process, which is equivalent to the sewage inlet connecting portion 11 can expand and become thick in the assembling process, which can reduce the difficulty of sleeving the sewage inlet connecting portion 11 on the sewage discharge connecting portion 23, and further improve the assembling efficiency. And the expanded part of the sewage inlet connecting part 11 can be tightened in the subsequent screwing process of the thread fastening sleeve 3, so that the sewage inlet connecting part 11 is ensured not to crack to influence the use reliability of the sewage discharging box 10.

Especially, the inner side wall of the sewage inlet connecting part 11 is also provided with the annular flange 231 for hooking the sewage discharge connecting part 23, and the arrangement of the notch 112 can reduce the difficulty of the clamping protrusion 111 to cross the annular flange 231 and reduce the interference force of the clamping protrusion 111 and the annular flange 231, so that the installation difficulty is reduced, and the installation efficiency is improved.

In an exemplary embodiment, as shown in fig. 6 and 7, the slit 112 extends in the axial direction of the dirt intake connection 11 and penetrates through an end of the dirt intake connection 11 near the bowl 21.

Like this, advance dirty connecting portion 11 and be close to the one end of urinal 21 and can become thick in the assembling process for it forms flaring structure to advance dirty connecting portion 11, is favorable to further reducing like this and advances the degree of difficulty that dirty connecting portion 11 suit is to blowdown connecting portion 23, thereby improves assembly efficiency. And this also facilitates the shaping of the cut 112.

In an exemplary embodiment, as shown in fig. 6 and 7, the length of the slit 112 is less than the axial length of the soil inlet connection 11.

Thus, the part of the sewage inlet connecting part 11 close to the toilet bowl 21 can be expanded and deformed, so that the sewage inlet connecting part 11 can be smoothly and quickly sleeved on the sewage discharge connecting part 23; the part of the dirt intake connecting portion 11 away from the toilet bowl 21 cannot be expanded and deformed, and is complete in the circumferential direction, and since the part is close to the dirt intake opening 12, it is advantageous to prevent dirt or odor from leaking out of the part.

As shown in fig. 6 and 7, the notch 112 starts at an end (i.e., a front end) of the dirt intake connection 11 away from the dirt intake port 12, and extends rearward in the axial direction of the dirt intake connection 11. The slits 112 penetrate the inner and outer sidewalls of the dirt-intake connecting portion 11 in the radial direction of the dirt-intake connecting portion 11.

In one example, as shown in fig. 6, 7 and 11, the number of the slits 112 is plural, and the plural slits 112 are arranged at intervals, such as uniformly, in the circumferential direction of the dirt intake connecting portion 11.

For the solution that the inner sidewall of the dirt intake connecting portion 11 is provided with the locking protrusion 111, the notch 112 and the locking protrusion 111 may be staggered with each other, as shown in fig. 11.

Such as: the number of the slits 112 on the dirt intake connecting portion 11 may be 2, 3, 4, 5, 6, 7, 8, etc. The width and depth of all the slits 112 may be set to be the same.

The plurality of notches 112 are beneficial to increasing the expansion degree of the dirt inlet connecting part 11 on one hand, and further reducing the installation difficulty; on the other hand is favorable to the dispersion to advance dirty connecting portion 11 because of the effort that the expansion deformation received for it is more balanced to advance dirty connecting portion 11 atress, and then reduces and advances dirty connecting portion 11 because of the excessive risk that leads to tearing the inefficacy of expanding.

In one example, as shown in fig. 6 and 7, the length of the notch 112 is greater than the width of the catching protrusion 111 in the axial direction of the dirt intake connecting portion 11.

In an exemplary embodiment, the axial length of the screw fastening sleeve 3 is smaller than the axial length of the dirt intake connection 11, as shown in fig. 9.

Thus, the screw fastening sleeve 3 can be pre-fitted on the dirt intake connecting portion 11 and screwed to a position of the dirt intake connecting portion 11 away from the toilet bowl 21. The dirt intake connection 11 can be fitted to the dirt discharge connection 23 with a threaded fastening sleeve 3. When the sewage inlet connecting part 11 is sleeved in place, the threaded fastening sleeve 3 is reversely screwed, so that the threaded fastening sleeve 3 rotates to the part of the sewage inlet connecting part 11 close to the urinal 21, the part is radially compressed, and the sewage inlet connecting part 11 is tightly connected with the sewage discharge connecting part 23. In addition, this also contributes to avoiding the loss of the screw clamp 3.

Still be equipped with the scheme of incision 112 to advancing dirty connecting portion 11, screw fastening cover 3 cover is on advancing dirty connecting portion 11, can also avoid incision 112 to extend backward at the bloated in-process and lead to advancing dirty connecting portion 11 and torn to improve the reliability of advancing dirty connecting portion 11.

The specific screwing direction of the screw clamp 3 is not limited, for example: the screw thread fastening sleeve 3 is screwed to the rear part of the sewage inlet connecting part 11 along the anticlockwise direction, and when the sewage inlet connecting part 11 is sleeved in place, the screw thread fastening sleeve 3 is screwed to the front part of the sewage inlet connecting part 11 along the pointer direction.

In an exemplary embodiment, an end of the threaded fastener sleeve 3 near the bowl 21 abuts against the toilet body 2, as shown in fig. 8 and 9.

Thus, during assembly, when the screw fastening sleeve 3 is screwed to contact the toilet body 2, the continued screwing can be stopped. Thus, the toilet body 2 has a positioning function for assembling the screw fastening sleeve 3, and the screw fastening sleeve 3 can be prevented from being excessively screwed.

In an exemplary embodiment, the outer side wall of the screw fastening sleeve 3 is provided with an indicating mark.

Therefore, the installation worker can conveniently rotate the threaded fastening sleeve 3 in the correct direction according to the indication identification part, the process of assembling the threaded fastening sleeve 3 in a forward and reverse trial mode is avoided, and the assembly efficiency of the closestool system is improved.

In one example, the indicator mark is a ledge 31 provided at the end of the threaded fastener sleeve 3, as shown in fig. 5 and 9.

Like this, protruding edge 31 both can play the effect of pilot sign, still is favorable to increasing the rotatory moment of screw fastening cover 3, is favorable to reducing the effort of twisting screw fastening cover 3 and applying, and then further reduces the installation degree of difficulty, improves assembly efficiency.

Of course, the indication mark portion is not limited to this form, and may be contents such as an indication arrow and an indication character.

In an exemplary embodiment, the toilet bowl system further includes a first sealing member (not shown), at least one of the sewage inlet connection portion 11 and the sewage discharge connection portion 23 is provided with a first mounting groove (not shown), and the first sealing member is mounted in the first mounting groove and abuts against an axial end surface of the sewage inlet connection portion 11 and an axial end surface of the sewage discharge connection portion 23 to form an end surface seal.

The first sealing element can realize axial sealing of the sewage draining connecting part 23 of the sewage inlet connecting part 11, and is beneficial to preventing sewage or odor from leaking outwards between the sewage inlet connecting part 11 and the sewage draining connecting part 23, thereby being beneficial to improving the reliability of the toilet system and improving the use experience of a user.

In an exemplary embodiment, the toilet system further comprises a second sealing member (not shown), at least one of the dirt intake connection 11 and the dirt discharge connection 23 being provided with a second mounting groove (not shown), the second sealing member being mounted in the second mounting groove and abutting a radially inner end of the dirt intake connection 11 and a radially outer end of the dirt discharge connection 23 to form a radial seal.

The second sealing member can realize advancing dirty connecting portion 11 and blowdown connecting portion 23 radial seal, also is favorable to preventing filth or foul smell from advancing between dirty connecting portion 11 and the blowdown connecting portion 23 and outwards revealing to be favorable to improving toilet system's reliability, improve user's use and experience.

In an exemplary embodiment, as shown in fig. 9, the drain connecting portion 23 is provided with a sealing groove 232, and a sealing ring 4 is arranged in the sealing groove 232.

The inner side wall of the sewage inlet connecting part 11 is provided with a stopping bulge 114, and the stopping bulge 114 is in stopping fit with one end of the sewage discharge connecting part 23 far away from the urinal 21.

The outer side wall of the sealing ring 4 abuts against the inner side wall of the sewage inlet connecting part 11, and the axial end face of the sealing ring 4 far away from the urinal 21 abuts against the stop bulge 114.

In this solution, the cooperation of the stopping protrusion 114 and the dirt discharging connecting portion 23 can play a positioning role in assembling the dirt discharging box 10, and prevent the dirt discharging box 10 from being excessively pushed to the dirt feeding connecting portion 11 along the axial direction.

Because the inside wall of sealing washer 4 and the lateral wall of blowdown connecting portion 23 support against, and the outside wall of sealing washer 4 and the inside wall of advancing dirty connecting portion 11 support against, therefore can realize advancing the radial seal between dirty connecting portion 11 and the blowdown connecting portion 23. Since the axial end surface (i.e., the front end surface) of the seal ring 4 close to the toilet bowl 21 is in contact with the waste connection portion 23 and the axial end surface (i.e., the rear end surface) far from the toilet bowl 21 is abutted against the stopper protrusion 114, axial sealing between the waste connection portion 11 and the waste connection portion 23 can be achieved.

So, utilize a sealing washer 4 can realize advancing the axial seal and the radial seal between dirty connecting portion 11 and the blowdown connecting portion 23, effectively improved the sealing reliability of blowdown box 10 and closestool body 2, and simple structure is favorable to reduce cost, simplifies the installation procedure.

In one example, the sealing groove 232 is surrounded by the portion of the outer wall of the tubular portion 233 located behind the annular flange 231 and the annular flange 231, so that the rear end of the sealing groove 232 is open and the radial outer end is open. The entire sewage connection portion 23 is relatively simple in structure.

In one example, as shown in fig. 8 and 9, a seal ring 4 is provided in the seal groove 232, and since the seal ring 4 has elasticity, in order to achieve a tighter seal, the radial thickness of the seal ring 4 when it is not compressed is set to be greater than the radial thickness of the annular flange 231. So, when advancing dirty connecting portion 11 and blowdown connecting portion 23 cover and establish the completion back, sealing washer 4 is because elasticity of self and along radial to advancing dirty connecting portion 11 and blowdown connecting portion 23 and exert pressure simultaneously for it reaches good radial seal effect to advance between dirty connecting portion 11 and the blowdown connecting portion 23.

Similarly, the axial width of the uncompressed seal ring 4 is set to be greater than the distance from the end of the annular flange 231 remote from the toilet bowl 21 to the stopper projection 114.
