[0025] Referring to Figures 1-2 As shown in the utility model embodiment, the sewage backflow prevention type toilet comprises a toilet body 1, a connecting block 101 is fixedly installed at one end of the toilet body 1, a plug-in opening 102 is formed at one end of the connecting block 101, and a backflow prevention mechanism 2 is plugged into the plug-in opening 102, so that the backflow prevention mechanism 2 can be in communication with a sewage pipe 103 in the toilet body 1.

[0026] In use, the backflow prevention mechanism 2 is plugged into the plug-in opening 102 in the toilet body 1, so that the backflow prevention mechanism 2 is in communication with the sewage pipe 103 in the toilet body 1. When the toilet body 1 is flushed, the sewage in the sewage pipe 103 flows into the backflow prevention mechanism 2 and is discharged into the sewer, so that when the sewage backflows, the sewage first flows into the backflow prevention mechanism 2, and the backflow prevention mechanism 2 is sealed and blocked by the buoyancy of the sewage, thereby effectively preventing the sewage from flowing back from the sewer into the toilet body 1, avoiding the sanitary problems and safety hazards caused by the sewage, protecting the health and safety of the user, allowing the sewage to be intercepted and treated in time when backflowing, not directly entering the toilet, being conducive to keeping the toilet clean, improving the sanitary standard, and creating a healthy use environment for the user.

[0027] As Figures 3-4 shown, the backflow prevention mechanism 2 comprises a plug-in block 201, the plug-in block 201 can be plugged into the plug-in opening 102, and a communication opening 202 is formed in the upper surface of the plug-in block 201, so that the plug-in block 201 plugged into the plug-in opening 102 can drive the communication opening 202 to be in communication with the sewage pipe 103 in the toilet body 1.

[0028] A sealing ring 203 is arranged on the peripheral surface of the communication opening 202 of the plug-in block 201, so that the sealing ring 203 can be in contact with the periphery of the connection between the communication opening 202 and the sewage pipe 103 to fill and seal.

[0029] An embedded groove 207 is formed at one end of the plug-in block 201, and a U-shaped pull rod 208 is rotatably installed in the embedded groove 207.

[0031] The diameter of the floating ball 205 is greater than the caliber of the communication port 202, so that when the sewage backflow enters the spherical groove 206, the floating ball 205 can be lifted by the buoyancy generated by the sewage to seal and block the communication port 202.

[0032] When the toilet body 1 is flushed, the sewage enters the communication port 202 and the spherical groove 206 in sequence along the sewage pipe 103, and is discharged into the sewer, so that when the sewage backflow occurs, the sewage can first enter the spherical groove 206, and the floating ball 205 in the spherical groove 206 can be lifted by the buoyancy generated by the entering sewage to seal and block the communication port 202, and the floating ball 205 can be vertically upwardly slid on the outer surface of the L-shaped slide rod 204 during the lifting process, so as to ensure that the floating ball 205 can be accurately blocked at the center of the communication port 202, effectively prevent the sewage backflow, and accurately seal to more reliably prevent the sewage backflow, improve the protection effect, and make the floating ball 205 automatically lift and block the communication port 202 by the buoyancy, without manual intervention, to realize the automatic blocking function, which simplifies the operation steps and improves the use convenience.

[0033] As described above, when the sewage enters the spherical groove 206, the floating ball 205 can be automatically lifted and blocked in the communication port 202 by the buoyancy, without manual intervention, to realize the automatic blocking function, and the lifting by the buoyancy is not easily affected by external factors, has strong reliability, and can effectively prevent the sewage backflow in daily use or in an emergency.
