  • Suction de-clogger system and method
    Patent number: 11813131
    Abstract: A declogging assembly (20) is configured for use with a suction conduit (10). The suction conduit has a head (14) at a first end (15) and a vacuum tube connection (16) at a second end (17). The assembly includes a body (30). The body defines a first aperture (32), a second aperture (34), and a third aperture (36). The assembly also includes a plug (40) disposed within the body (30). The plug has a surface (42) configured to contact the head (14) of the suction conduit (10) so as to move the plug from a first position, in which the first aperture (32) is in fluid communication with the second aperture (34), to a second position, in which the first aperture (32) is in fluid communication with the third aperture (36). The assembly (20) also includes a biasing member (50) configured to bias the plug into the first position.
