[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below. Example

[0027] like Figures 1-5 As shown, in order to solve the existing problems, this utility model discloses an odor-blocking device, including a cover plate 1, a housing 2 connected to the bottom of the cover plate 1 by bolts, a docking ring 3 connected to the bottom of the housing 2, the docking ring 3 having a plurality of docking holes 4 arranged in a circle, a motor component 5 connected to the outer side of the housing 2, a rotating component 6 rotatably connected to the inner wall of the housing 2, a through hole provided in the cover plate 1, and a docking component 7 connected to the bottom of the cover plate 1.

[0028] The motor component 5 includes a motor housing 501 connected to the outside of the housing 2. A telescopic rod housing 502 is connected to the inner wall of the motor housing 501. An electric telescopic rod 504 is connected to the inner wall of the telescopic rod housing 502. A control connector 503 is connected to the side of the electric telescopic rod 504. A transmission head 505 is connected to the telescopic end of the electric telescopic rod 504. A rotating shaft 506 is rotatably connected to the other end of the transmission head 505. A transmission component 507 is rotatably connected to the rotating shaft 506. A rotating transmission component 508 is rotatably connected to the other end of the transmission component 507.

[0029] The other end of the rotating transmission component 508 is connected to the transmission shaft 510, and the side of the housing 2 is connected to the rotating connector 509, which is rotatably connected to the transmission shaft 510.

[0030] The rotating component 6 includes a rotating docking part 601 connected to the inner wall side of the housing 2. The rotating docking part 601 is rotatably connected to the drive shaft 510. A connector 602 is connected to the outer arc surface of the drive shaft 510. The connector 602 is L-shaped. The center of the connector 602 is in contact with the outer arc surface of the drive shaft 510. A blocking part 603 is connected to one end of the connector 602. A counterweight 604 is connected to the other end of the connector 602. A sealing part 605 is provided on the outer arc surface of the blocking part 603.

[0031] The specific working principle is as follows: This device can block the backflow of odor from toilet drain water through the blocking component 603 structure. Compared with traditional devices, this device can be operated in a variety of control methods.

[0032] When this device is in use, the assembly and installation difficulty of the device is reduced by connecting the drain pipe to the docking ring 3 at the bottom of the device housing 2. At the same time, the through hole at the top of the cover plate 1 can ensure the docking stability of the device. When draining, the electric telescopic rod 504 drives the transmission head 505 to slide linearly, and at the same time, the transmission component 507 and the rotation transmission component 508 can drive the transmission shaft 510 to rotate. The rotation of the transmission shaft 510 can drive the blocking component 603 to tilt and flip, thereby opening the internal communication state of the docking housing 701.

[0033] When the device loses external power input, the weight of the counterweight 604 causes the blocking member 603 to abut against the bottom of the docking housing 701, thereby achieving a sealing effect in the absence of power. At the same time, when the device is flushed by water, it can drive the drive shaft 510 to rotate, thereby achieving the water flushing effect of the device. The counterweight 604 drives the blocking member 603 to flip in the opposite direction, thereby restoring the sealing effect. Example

The docking housing 701 is located directly above the docking ring 3. The inner diameter of the docking housing 701 is the same as the inner diameter of the docking ring 3.

[0036] The specific working principle is as follows: This device can effectively improve the stability of the toilet flushing process. At the same time, by connecting and linking with the toilet system, this device can achieve stable flushing while ensuring timely sealing of the inside of the casing 2.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
