[0001] The utility model relates to the technical field of sanitary wares, in particular to a toilet offsetter. Background Art
[0002] A toilet offsetter, also called a deflector or a sewage offsetter, is mainly used during toilet installation. It is a pipe fitting used when the position of the toilet outlet does not correspond to that of the lower sewage pipe due to the fixed positions of the washroom wall and the sewage outlet.
[0003] However, most traditional toilet offsetters do not have an anti-odor function, and a right-angle transition is adopted in the inner cavity of the toilet offsetter, so that when discharging sewage, dirt will fall inside the toilet offsetter, resulting in the problems of odor backflow and toilet blockage. Summary of the Utility Model
[0004] To solve the above technical problems or at least partially solve the above technical problems, the present application provides a toilet offsetter.
[0005] The present application provides a toilet offsetter, including:
[0006] An offsetter body, which includes a sewage inlet pipe and a sewage discharge pipe communicated with the sewage inlet pipe. An outflow channel for communicating with the sewage discharge pipe is provided at one end of the sewage inlet pipe close to the sewage discharge pipe, and the inner diameter of the outflow channel gradually decreases along the direction of sewage discharge;
[0007] A seal, which is arranged at the sewage inlet of the sewage inlet pipe and is used for sealing the toilet outlet pipe inserted into the interior of the sewage inlet pipe. The seal is provided with an opening communicated with the sewage inlet pipe;
[0008] A gland, which is connected to one end of the sewage inlet pipe far from the sewage discharge pipe and is connected to the seal. The gland is provided with an insertion port communicated with the sewage inlet pipe;
[0009] Wherein, the inner diameter of the toilet outlet pipe and the maximum and minimum inner diameters of the outflow channel satisfy the following relationship: R 1 ≤R≤R 2 , R is the inner diameter of the toilet outlet pipe, R 1 is the minimum inner diameter of the outflow channel, and R 2 is the maximum inner diameter of the outflow channel.
[0010] In a possible implementation manner, an angle less than 45° is formed between the inner wall of the outflow channel and the inner wall of the sewage discharge pipe.
[0011] In a possible implementation manner, the angle is between 25° and 30°.
[0012] In a possible implementation manner, the seal is made of an elastomer, and the hardness of the seal is between 45 and 60 Shore A.
[0013] In a possible implementation manner, the seal includes a sealing ring and a sealing lip obliquely arranged inside the sealing ring. The upper end of the sealing lip is connected to the inner side surface of the sealing ring. The sealing lip is provided with the opening, and an installation position is formed between the sealing lip and the sealing ring. The installation position is used for assembling with the sewage inlet of the sewage inlet pipe;
[0014] Wherein, when the seal is assembled to the sewage inlet of the sewage inlet pipe, the sealing lip is located inside the sewage inlet pipe, and the inner side surface of the sealing ring abuts against the outer wall of the sewage inlet pipe, and the outer side surface of the sealing ring abuts against the inner wall of the gland.
[0015] In a possible implementation manner, a first groove is formed on the inner side surface of the sealing ring, and a first convex block extending outward is provided at the top edge position of the sewage inlet pipe.

[0018] In a possible implementation manner, the sewage inlet pipe and the sewage discharge pipe are integrally injection-molded and connected.
[0019] In a possible implementation manner, the inner diameter of the sewage inlet pipe is larger than the inner diameter of the sewage discharge pipe.
[0020] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art:
[0021] By installing a seal at the sewage inlet of the sewage inlet pipe, the seal is firmly installed on the sewage inlet pipe. When the toilet outlet pipe is inserted into the sewage inlet pipe from the insertion port, the seal will closely adhere to the outer surface of the toilet outlet pipe, preventing sewage from seeping out from the connection between the toilet outlet pipe and the sewage inlet pipe.

[0033] Please refer to Figures 1 to 3, this application provides a toilet shifter, which includes a shifter body 10, a seal 20, and a gland 30. The shifter body 10 includes a sewage inlet pipe 11 and a sewage discharge pipe 12 connected to the sewage inlet pipe 11. One end of the sewage inlet pipe 11 close to the sewage discharge pipe 12 is provided with an outflow channel 11a for connecting to the sewage discharge pipe 12, and the inner diameter of the outflow channel 11a gradually decreases along the direction of sewage discharge. The seal 20 is arranged at the sewage inlet of the sewage inlet pipe 11 for sealing the toilet outlet pipe inserted into the interior of the sewage inlet pipe 11. The seal 20 is provided with an opening 40 connected to the sewage inlet pipe 11. The gland 30 is connected to the end of the sewage inlet pipe 11 away from the sewage discharge pipe 12 and is connected to the seal 20. The gland 30 is provided with an insertion port connected to the sewage inlet pipe 11.
[0034] Among them, the inner diameter of the toilet outlet pipe and the maximum and minimum inner diameters of the outflow channel 11a satisfy the following relationship: R 1 ≤R≤R 2 , where R is the inner diameter of the toilet outlet pipe, R 1 is the minimum inner diameter of the outflow channel 11a, and R 2 is the maximum inner diameter of the outflow channel 11a.
[0035] Exemplarily, the sewage inlet pipe 11 and the sewage discharge pipe 12 can be integrally injection-molded into one body, so that the connection between the sewage inlet pipe 11 and the sewage discharge pipe 12 forms a sealed state, and sewage will not overflow from the connection between the sewage inlet pipe 11 and the sewage discharge pipe 12.
[0036] Exemplarily, since the toilet outlet pipe is vertically inserted into the sewage inlet pipe 11, and the outflow channel 11a is used to connect the sewage inlet pipe 11 and the sewage discharge pipe 12, the sewage flowing out of the toilet outlet pipe will flow into the sewage discharge pipe 12 through the outflow channel 11a. If the inner diameter of the toilet outlet pipe is greater than the maximum inner diameter of the outflow channel 11a, some sewage will remain inside the sewage inlet pipe 11, which will lead to problems such as odor backflow and toilet blockage. In this regard, this application makes the inner diameter of the toilet outlet pipe and the maximum and minimum inner diameters of the outflow channel 11a satisfy the following relationship: R 1 ≤R≤R 2 , to ensure that the sewage flowing out after the toilet outlet pipe is inserted into the sewage inlet pipe 11 completely flows into the outflow channel 11a, and no part of the sewage remains inside the sewage inlet pipe 11, which can effectively prevent problems such as odor backflow and toilet blockage.
[0037] The toilet shifter based on the above technical features installs a seal 20 at the sewage inlet of the sewage inlet pipe 11, so that the seal 20 is firmly installed on the sewage inlet pipe 11. When the toilet outlet pipe is inserted into the sewage inlet pipe 11 from the insertion port, the seal 20 will closely adhere to the outer surface of the toilet outlet pipe, preventing sewage from seeping out from the connection between the toilet outlet pipe and the sewage inlet pipe 11. The seal 20 is also pressed by a gland 30 to prevent the seal 20 from jumping during the insertion of the toilet outlet pipe, which may affect the sealing effect. At the same time, the inner diameter of the outflow channel 11a is set to gradually decrease along the direction of sewage discharge. The minimum inner diameter of the outflow channel 11a needs to be set to be less than or equal to the inner diameter of the toilet outlet pipe, and the maximum inner diameter is set to be greater than or equal to the inner diameter of the toilet outlet pipe, so as to ensure that the sewage flowing out after the toilet outlet pipe is inserted into the sewage inlet pipe 11 completely flows into the outflow channel 11a, and no part of the sewage remains inside the sewage inlet pipe 11, effectively preventing the problems of back odor and toilet blockage.
[0038] In a possible implementation, an angle less than 45° is formed between the inner wall of the outflow channel 11a and the inner wall of the sewage discharge pipe 12. Among them, the angle is between 25° and 30°. In this way, the sewage discharged from the toilet can flow into the sewage discharge pipe 12 more quickly and be discharged through the sewage discharge pipe 12, avoiding the problems of back odor of the odor and toilet blockage caused by the sewage hanging inside the sewage inlet pipe 11.
[0039] In a possible implementation, the seal 20 is made of an elastomer, and the hardness of the seal 20 is between 45 and 60 Shore A.
[0040] Exemplarily, the seal 20 is made of an elastomer so that the made seal 20 has elasticity. When the toilet outlet pipe is inserted into the sewage inlet pipe 11, the seal 20 is squeezed and elongated downward. After the toilet outlet pipe is installed in place, the seal 20 will start to contract due to its own elasticity, thus closely adhering to the outer surface of the toilet outlet pipe and preventing sewage from seeping out from the connection between the toilet outlet pipe and the sewage inlet pipe 11.
[0041] It should be noted that the elastomer can be made of flexible rubber or other commonly used elastic materials in the prior art, and no limitation is made thereto. In addition, during the process of making the seal 20 with an elastomer, lubricating oil can be added to the elastomer material to make the surface of the made seal 20 smooth, which can play a role in reducing friction and is also more convenient for installation.
[0042] Exemplarily, setting the hardness of the seal 20 within the above range is for the toilet outlet pipe to be inserted more easily and reduce the installation difficulty. It should be noted that Shore A refers to the Shore hardness, and the Shore hardness is a unit used to represent the hardness grade of metal, plastic, and rubber materials.
[0043] In a possible implementation, the seal 20 includes a sealing ring 21 and a sealing lip 22 inclined inside the sealing ring 21. The upper end of the sealing lip 22 is connected to the inner side surface of the sealing ring 21. The sealing lip 22 is provided with an opening 40, and an installation position 50 is formed between the sealing lip 22 and the sealing ring 21. The installation position 50 is used for assembling with the sewage inlet of the sewage inlet pipe 11. Among them, when the seal 20 is assembled to the sewage inlet of the sewage inlet pipe 11, the sealing lip 22 is located inside the sewage inlet pipe 11, and the inner side surface of the sealing ring 21 abuts against the outer wall of the sewage inlet pipe 11, and the outer side surface of the sealing ring 21 abuts against the inner wall of the gland 30.
[0044] Exemplarily, after the seal 20 is assembled to the sewage inlet of the sewage inlet pipe 11, the gland 30 is installed at the sewage inlet of the sewage inlet pipe 11 so that the inner top surface of the gland 30 presses the top surface of the sealing ring 21, and the inner wall of the gland 30 presses the outer side surface of the sealing ring 21, so that the seal 20 is tightly fixed at the sewage inlet of the sewage inlet pipe 11, having a good sealing effect.
[0045] In addition, during the process of inserting the toilet outlet pipe into the sewage inlet of the sewage inlet pipe 11, the sealing lip 22 will be extruded by the outer surface of the toilet outlet pipe and elongate downward. After the toilet outlet pipe is installed in place, the sealing lip 22 tightens due to its own elasticity, and then closely fits with the toilet outlet pipe, thereby ensuring that there is no water leakage at the connection between the toilet outlet pipe and the sewage inlet pipe 11.
[0046] In a possible implementation, a first groove 21a is formed on the inner side surface of the sealing ring 21, and a first convex block 11b extending outward is provided at the top edge position of the sewage inlet pipe 11. The first convex block 11b is adapted to the first groove 21a to fix the sealing ring 21 on the sewage inlet pipe 11.
[0047] Exemplarily, by forming a first groove 21a on the inner side surface of the sealing ring 21 and correspondingly providing a first convex block 11b at the top edge position of the sewage inlet pipe 11, the sealing ring 21 is firmly connected to the sewage inlet pipe 11 by the first convex block 11b being snapped into the first groove 21a, which can ensure that the sealing ring 21 does not move during the process of inserting the toilet outlet pipe into the sewage inlet pipe 11 and can guarantee the sealing effect on the toilet outlet pipe.
[0048] In a possible implementation, a second groove 21b is formed on the outer side surface of the sealing ring 21, and a second convex block 30a extending inward is provided on the inner wall of the gland 30. The second convex block 30a is adapted to the second groove 21b to fixedly connect the gland 30 and the sealing ring 21.
[0049] Exemplarily, after installing the sealing ring 21 at the sewage inlet of the sewage inlet pipe 11, the gland 30 is connected to the sewage inlet of the sewage inlet pipe 11. At this time, the second convex block 30a on the inner wall of the gland 30 is snapped into the second groove 21b, so that the connection between the gland 30 and the sealing ring 21 is more firm, preventing the gland 30 from loosening relative to the sealing ring 21, ensuring that the sealing ring 21 is tightened, and preventing the sealing ring 21 from jumping during the insertion of the toilet outlet pipe, which may affect the sealing performance.
[0050] In a possible implementation manner, a plurality of raised ribs 22a are distributed on the surface of the sealing lip 22 close to the sewage inlet. In this way, by providing the raised ribs 22a on the surface of the sealing lip 22 close to the sewage inlet, after the toilet outlet pipe is inserted into the sewage inlet pipe 11, the raised ribs 22a can be in close contact with the outer surface of the toilet outlet pipe, which is beneficial to improving the sealing performance.
[0051] In a possible implementation manner, the inner diameter of the sewage inlet pipe 11 is larger than the inner diameter of the sewage discharge pipe 12. In this way, after the sewage flowing out of the toilet outlet pipe enters the sewage inlet pipe 11, the outflow of the sewage can be accelerated, preventing the sewage from being blocked in the sewage inlet pipe 11.
[0052] It can be understood that the above embodiments only represent the preferred implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention should fall within the scope covered by the claims of the present invention.
