The driving device 5 comprises a turn-over motor 51 and a rotary connector 52 (i.e. a rotor) fixed on the output rotating shaft of the turn-over motor 51, and a driving connection part 22 is provided on the surface of one side of the sewage pipe 2 opposite to the inlet end 21 for connecting the rotary connector 52 of the driving device 5, so that the rotary connector 52 drives the sewage pipe 2 to rotate.
Wherein the rotation axis of the rotary joint 52, the rotation axis of the sewage pipe 2, the central axis of the inlet end 21 of the sewage pipe 2, and the central axis of the sewage inlet 13 may be arranged in a common line.
The initial position of the turnover motor 51 of the blowdown box assembly of the embodiment of the application and the stroke angle range of the output rotating shaft are set, so that the orientation switching of the water outlet end of the blowdown pipe 2 can be realized, and the switching of the blowdown box assembly between a blowdown state and a water seal state can be executed. As shown in figure 6a, the water outlet end of the sewage draining pipe 2 faces upwards and deviates from the sewage draining outlet 14 of the sewage draining box 1, and the water entering from the sewage draining inlet 13 is sealed in the pipe inner cavity of the sewage draining pipe 3, thereby realizing water sealing. The turning motor 51 is started, the turning motor 51 drives the rotary connecting piece 52, the driving connecting part 22 and the sewage discharge pipe 2 to rotate around the central axis of the inlet end 21, the sewage discharge position is reached, the sewage discharge state is entered, as shown in fig. 6b, the water outlet end of the sewage discharge pipe 2 faces downwards at the moment, and sewage can be discharged from the sewage discharge outlet 14 through the sewage discharge pipe 2, so that the sewage discharge function is realized.
The embodiment of the application also provides a closestool (not shown), which comprises a closestool body, wherein the closestool body is provided with a sewage discharge outlet. The closestool also comprises a sewage discharge box component of the closestool provided by any one of the embodiments, and the sewage discharge port is communicated with the sewage discharge inlet 13 of the sewage discharge box component.
When the blowdown box subassembly of this application embodiment is used for the closestool, the drain that sets up the closestool is connected with the blowdown import 13 of blowdown box subassembly, can realize the switching of closestool at blowdown state and water seal state. The soil discharge outlet 14 of the soil discharge box 1 may be communicated with a sewer so that when the soil discharge pipe 2 is rotated to a soil discharge state, soil can be discharged into the sewer after being discharged through the soil discharge outlet 14.
In summary, the embodiment of the application mainly seals the inlet end of the drain pipe through the sealing ring on the drain pipe, and the elastic piece for assisting pre-tightening ensures that the main sealing lip of the sealing ring can be tightly attached to the inlet end of the drain pipe, and the sealing function can be achieved without too large interference fit between the main sealing lip and the inlet end of the drain pipe, so that the smooth rotation of the drain pipe is ensured; meanwhile, even if the sealing ring is abraded in the long-term use process, the pre-tightening of the elastic piece still can ensure that the main sealing lip is tightly attached to the inlet end of the sewage draining pipe, and the problems of sealing stability and long service life of the sewage draining pipe in the rotating process are solved.
Although the embodiments disclosed in the present application are described above, the descriptions are only for the convenience of understanding the present application, and are not intended to limit the present application. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
