All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In order to solve the problem of poor sealing between the ceramic body of the toilet and the sewage pipe in the prior art, the present invention provides a pipeline sealing structure and a toilet. Among them, the following toilet includes the following pipeline sealing structure.

[0031] Embodiment 1

[0032] As Figures 1 to 4 shown, the present application provides a pipeline sealing structure for sealing the connection between the sewage pipe of the toilet and the ceramic body 90. The pipeline sealing structure includes a main body 10, a first sealing rib 20 and a first sealing periphery 30. The main body 10 has a central channel. The first sealing rib 20 is disposed on at least one of the inner and outer circumferential surfaces of the main body 10 and extends along the circumferential direction of the main body 10. The first sealing periphery 30 is located at one end of the main body 10 away from the ceramic body 90 and extends radially inwards or outwards. The second sealing rib 40 is disposed on at least one side surface of the first sealing periphery 30 in the axial direction, and the second sealing rib 40 extends along the circumferential direction of the first sealing periphery 30.

[0033] By respectively providing the first sealing rib 20 on the main body portion 10 and the second sealing rib 40 on the first sealing periphery 30, double sealing in the radial and axial directions is achieved, greatly improving the sealing effect of the pipeline sealing structure and ensuring a high sealing performance between the ceramic body of the toilet and the sewage pipe.

[0034] It can be understood that in this embodiment, both the first sealing rib 20 and the second sealing rib 40 are annular ribs.

[0035] In this embodiment, there are multiple first sealing ribs 20, and the multiple first sealing ribs 20 are arranged at intervals along the axial direction of the main body portion 10. Correspondingly, there are also multiple second sealing ribs 40, and the multiple second sealing ribs 40 are arranged at intervals along the radial direction of the first sealing periphery 30. That is to say, the multiple second sealing ribs 40 are multiple rings with different sizes. Through the above arrangement, the double sealing effect of the pipeline sealing structure in the radial and axial directions can be improved.

[0036] As Figures 2 to 4 shown, the toilet further includes a connecting pipe 50 and a second sealing periphery 60 located on the outer peripheral surface of the connecting pipe 50, which is used to connect the sewage pipe and the ceramic body 90. The ceramic body 90 includes a connecting portion 91, and the connecting portion 91 is provided with a receiving groove 911. The main body portion 10 is sleeved on the connecting pipe 50 and is jointly received in the receiving groove 911 with at least a part of the connecting pipe 50.

[0037] Specifically, as Figure 2 shown, the receiving groove 911 communicates with the internal sewage pipeline of the ceramic body 90, and the inner diameter of the receiving groove 911 is larger than the inner diameter of the internal sewage pipeline of the ceramic body 90. The connecting pipe 50 includes a first pipe section, a reduced-diameter section, and a second pipe section connected in sequence. The second sealing periphery 60 is located at the connection between the reduced-diameter section and the second pipe section. The diameter of the second pipe section is larger than that of the first pipe section, so as to extend into the receiving groove 911 and be able to abut against the bottom of the receiving groove 911.

[0038] In this embodiment, the first sealing rib 20 is provided on the outer peripheral surface of the main body portion 10, and the first sealing periphery 30 extends radially outward for fitting with the end faces of the second sealing periphery 60 and the connecting portion 91. One end of the main body portion 10 close to the ceramic body 90 has a third sealing periphery 70, and the third sealing periphery 70 extends radially inward for fitting with the end face of the connecting pipe 50 and the bottom surface of the receiving groove 911. Specifically, as Figure 2 shown, the second sealing periphery 60 includes a radial section 61 and an axial section 62 that extend and bend outward in sequence. The first sealing periphery 30 is respectively in contact with the radial section 61 and the end face of the connecting portion 91. The axial section 62 is adaptively sleeved on the outer peripheral surface of the connecting portion 91.

[0039] In this embodiment, the pipe sealing structure is similar to a pipe sleeve structure. It can be understood that the axial length of the pipe sealing structure is adapted to the depth of the accommodating groove 911, so that after the connecting pipe 50 and the second sealing periphery 60 press the pipe sealing structure into the accommodating groove 911, the connecting pipe 50 can exactly squeeze the third sealing periphery 70 against the bottom surface of the accommodating groove 911, and the second sealing periphery 60 can exactly squeeze the first sealing periphery 30 against the end surface of the connecting portion 91, ensuring the interference amount of axial sealing and thus ensuring the sealing effect.

[0040] In this embodiment, the edge portion of the first sealing rib 20 is bent in a direction away from the ceramic body 90. As Figure 2 shown, Figure 2 the arrow in is the negative pressure direction or the water flow direction. That is to say, the bending direction of the first sealing rib 20 is opposite to the water flow direction. The straight-through sealing method in the prior art is along the water flow direction. Under the negative pressure of siphon, the sealing surface is prone to expand along the negative pressure direction, thus there is a risk of poor sealing. Therefore, through the above settings, after the pipe sealing structure in this embodiment extends into the accommodating groove 911, the first sealing rib 20 and the ceramic body 90 will be sucked tighter under negative pressure, thereby ensuring the sealing effect at the connection between the ceramic body 90 of the toilet and the sewage pipe, preventing air leakage during siphon and causing the siphon to interrupt, and thus ensuring the normal use of the toilet.

[0041] In this embodiment, there is a gap between the first sealing rib 20 and the inner peripheral wall of the accommodating groove 911, and the gap is less than or equal to 2 mm. That is to say, the first sealing rib 20 and the connecting portion 91 are in clearance fit, so as to ensure the adjustable margin during assembly.

[0042] In this embodiment, the second sealing rib 40 is arranged on the side of the first sealing periphery 30 close to the ceramic body 90. Specifically, in this embodiment, the main body portion 10 is sleeved on the second pipe section of the connecting pipe 50, so there is already good sealing between the main body portion 10 and the second pipe section. Therefore, there is no need to arrange the first sealing rib 20 on the inner peripheral surface of the main body portion 10. Further, a plurality of rib structures can be arranged axially on the second pipe section to improve the sealing performance and connection firmness between the main body portion 10 and the second pipe section. On this basis, the second sealing periphery 60 squeezes the first sealing periphery 30 against the end surface of the connecting portion 91, and there is also good sealing between the second sealing periphery 60 and the first sealing periphery 30. Therefore, the second sealing rib 40 does not need to be arranged on the side of the first sealing periphery 30 away from the ceramic body 90. Of course, the first sealing rib 20 can also be arranged on the inner peripheral surface of the main body portion 10 at the same time, and the second sealing rib 40 can be arranged on the side of the first sealing periphery 30 away from the ceramic body 90 at the same time, which can be selected according to actual needs.

[0043] In this embodiment, the cross-section of the second sealing rib 40 is semi-circular. The second sealing rib 40 with the above shape can improve the sealing effect between the first sealing periphery 30 and the end face of the connecting portion 91. Of course, the second sealing rib 40 can also be of other shapes and can be selected according to actual needs.

[0044] As Figure 4 and Figure 6 shown, the present application also provides a toilet, which includes a ceramic body 90, a sewage pipe, and the above-mentioned pipe sealing structure. The pipe sealing structure is arranged at the connection between the sewage pipe and the ceramic body 90.

[0045] As Figures 2 to 4 shown, the toilet further includes a connecting pipe 50 and a second sealing periphery 60 located on the outer peripheral surface of the connecting pipe 50 for connecting the sewage pipe and the ceramic body 90. The ceramic body 90 includes a connecting portion 91. The connecting portion 91 is provided with a receiving groove 911. The main body portion 10 is sleeved on the connecting pipe 50 and at least a part of the connecting pipe 50 is jointly received in the receiving groove 911. The first sealing rib 20 is arranged on the outer peripheral surface of the main body portion 10. The first sealing periphery 30 extends radially outward for fitting with the second sealing periphery 60 and the end face of the connecting portion 91. One end of the main body portion 10 close to the ceramic body 90 has a third sealing periphery 70. The third sealing periphery 70 extends radially inward for fitting with the end face of the connecting pipe 50 and the bottom surface of the receiving groove 911.

[0046] As Figure 4 shown, the toilet further includes a fastener 80. An installation ear 64 is arranged on the second sealing periphery 60. A corresponding installation hole 92 is opened on the ceramic body 90. The fastener 80 passes through the installation ear 64 and enters the installation hole 92 to fasten the second sealing periphery 60 and the pipe sealing structure. In this embodiment, the fastener 80 is an expansion bolt. Of course, the fastener 80 can also be other components such as ordinary bolts and can be selected according to actual needs.

[0047] Embodiment Two

[0048] The difference between this embodiment and Embodiment One is that the specific structure of the pipe sealing structure is different from that of Embodiment One.

[0049] Specifically, as Figure 5As shown, the ceramic body 90 includes a connecting portion 91, and the connecting portion 91 communicates with the internal sewage pipeline of the ceramic body 90. The toilet also includes a connecting pipe 50 and a second sealing periphery 60 located at the end of the connecting pipe 50 for connecting the sewage pipe and the ceramic body 90. The second sealing periphery 60 includes a radial section 61 and an axial section 62 that sequentially extend and bend outward. The main body portion 10 and the second sealing periphery 60 are sequentially sleeved on the connecting portion 91, that is, the main body portion 10 is sleeved on the connecting portion 91, and then the second sealing periphery 60 is sleeved on the main body portion 10. The first sealing periphery 30 extends radially inward for fitting with the radial section 61 and the end face of the connecting portion 91. That is to say, in this embodiment, the connecting pipe 50 does not extend into the ceramic body 90, but is connected to the connecting portion 91 through the second sealing periphery 60.

[0050] In this embodiment, the first sealing rib 20 is provided on the inner peripheral surface and the outer peripheral surface of the main body portion 10. Similarly, the second sealing rib 40 is provided on both side surfaces of the first sealing periphery 30 along the axial direction. By providing sealing ribs on both sides of the main body portion 10 and the first sealing periphery 30, the overall sealing effect of the pipeline sealing structure can be improved.

[0051] As Figure 5 shown, one end of the main body portion 10 close to the ceramic body 90 has a first flared section 11. The second sealing periphery 60 further includes a second flared section 63. The second flared section 63 is sequentially connected to the axial section 62 and is correspondingly arranged with the first flared section 11. By providing the flared sections, it is convenient for the main body portion 10 and the second sealing periphery 60 to be aligned and connected to the connecting portion 91.

[0052] It should be noted that Figure 5 the arrow in

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: The pipeline sealing structure includes a main body portion 10, a first sealing rib 20 and a first sealing periphery 30. The main body portion 10 has a central channel. The first sealing rib 20 is provided on at least one of the inner and outer peripheral surfaces of the main body portion 10 and extends along the circumferential direction of the main body portion 10. The first sealing periphery 30 is located at one end of the main body portion 10 away from the ceramic body 90 and extends radially inward or outward. The second sealing rib 40 is provided on at least one side surface of the first sealing periphery 30 along the axial direction. The second sealing rib 40 extends along the circumferential direction of the first sealing periphery 30. In this way, by respectively providing the first sealing rib 20 and the second sealing rib 40 on the main body portion 10 and the first sealing periphery 30, double sealing in the radial and axial directions is achieved, greatly improving the sealing effect of the pipeline sealing structure and ensuring a high sealing performance between the ceramic body of the toilet and the sewage pipe.
