[0002] A toilet anti-odor plug is an important accessory for a toilet. It is usually made of PVC soft glue and installed at the bottom drainage outlet of the toilet. Its main function is to prevent the odor from the sewer from returning to the room. When the toilet flushes, the anti-odor plug can effectively block the odor and harmful gases from the sewer from entering the indoor space while draining water, keeping the air in the bathroom fresh.
[0003] The toilet drain pipe has a straight section and a curved section. At present, when the longer toilet anti-odor plugs on the market encounter the dead corner of the curved section, the anti-odor plug is deformed as a whole after bending, resulting in a decrease in the sealing performance of the anti-odor plug and easy sealing failure. Therefore, in view of the above phenomenon, a toilet flange anti-odor plug is proposed to meet the actual use needs. Content of the Utility Model

[0005] To solve the above technical problems, a toilet flange anti-odor plug provided by the utility model includes a connecting flange and an anti-odor plug body. A connecting groove is opened at the top of the connecting flange. The connecting groove includes a hexagonal groove for a nut to pass through and an arc groove for a threaded post to pass through. The hexagonal groove and the arc groove are integrally formed. The number of the connecting grooves is at least two. A countersunk head mounting groove is opened at the top of the connecting flange. The connecting flange is in a circular ring shape. The anti-odor plug body passes through the middle of the connecting flange. A pressing edge is integrally formed at the top edge of the anti-odor plug body. A continuous convex ring, a first sealing convex plate, a sealing convex ring and a second sealing convex plate are integrally formed on the surface of the anti-odor plug body. A missile mounting head is integrally formed on the bottom surface of the anti-odor plug body. A V-shaped annular groove is opened on the surface of the anti-odor plug body.
[0006] Preferably, the number of the first sealing convex plates is two. One first sealing convex plate is located below the continuous convex ring, and the other first sealing convex plate is located above the missile mounting head.
[0007] Preferably, the number of the sealing convex rings is three, and the number of the V-shaped annular grooves is three. The three V-shaped annular grooves are respectively located below the three sealing convex rings.
[0008] Preferably, the top of the pressing edge protrudes above the top of the connecting flange.
[0009] Compared with the related technology, a toilet flange anti-odor plug provided by the utility model has the following beneficial effects:
[0010] The utility model provides a toilet flange anti-odor plug. By designing a continuous raised ring, a first sealing raised plate, a second sealing raised plate and a plurality of sealing raised rings on the outer surface of the anti-odor plug body, the sealing effect is good. The designed V-shaped annular groove facilitates the use of tools such as scissors to cut it into a reserved section and a discarded section, and the appropriate cutting position can be selected according to the bending position of the sewer pipe. At least the continuous raised ring, the first sealing raised plate and the sealing raised ring are still left on the reserved section to ensure the sealing performance and solve the problem of eccentric installation of the sewer.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Embodiment, consisting of Figures 1-5Provided that, the utility model includes a connecting flange 1 and an anti-odor plug body 2. A connecting groove 11 is formed at the top of the connecting flange 1. The connecting groove 11 includes a hexagonal groove for a nut to pass through and an arc groove for a threaded post to pass through. The hexagonal groove and the arc groove are integrally formed. The number of the connecting grooves 11 is at least two. A countersunk head mounting groove 12 is formed at the top of the connecting flange 1. The connecting flange 1 is in a circular ring shape. The anti-odor plug body 2 passes through the middle of the connecting flange 1. A pressing edge 21 is integrally formed at the top edge of the anti-odor plug body 2. A continuous convex ring 22, a first sealing convex plate 23, a sealing convex ring 25 and a second sealing convex plate 27 are integrally formed on the surface of the anti-odor plug body 2. A missile mounting head 26 is integrally formed on the bottom surface of the anti-odor plug body 2. A V-shaped annular groove 24 is formed on the surface of the anti-odor plug body 2.
[0019] In this embodiment, before installation, the connecting flange 1 needs to be positioned and drilled around the toilet sewer pipe. The hole position matches the countersunk head mounting groove 12. Then, the connecting flange 1 is fixed using expansion screws or the like. Bolts matching the connecting groove 11 are provided at the position of the toilet bottom matching the connecting groove 11. After the bolts are inserted into the hexagonal groove and rotated by a certain angle, the edge of the toilet base and the ground are bonded and decorated using glue and waterproof materials, etc., to complete the installation of the toilet.
