  • a second gasket 160 is formed around the communication hole 310 in the inner wall of the dust receptacle 300 in order to prevent ingress of incoming air other than the incoming air drawn in from the hose connection pipe 120.
  • FIG. 3 shows the cover 400 (FIG. 7) of the dry/wet vacuum cleaner employing the hose connection apparatus when it is in an open condition, that is, when it pivoted about its axis (as shown in FIG.7).
  • the pair of guide shafts 144, 144' are in an upwardly protruded condition, since the guide shafts 144, 144' are mounted at the hose holder 110 so as to move vertically, so that they can take one of two vertical positions.
  • the secondary connection pipe 130 is moved to the first position wherein the large-diameter part 131 is inserted in the groove 115 of the hose holder 110. Therefore, the small-diameter part 132 of the secondary connection pipe 130 and the outer circumference of the dust receptacle 300 are separated by a predetermined distance from each other.
  • the hose connection apparatus is operated when the secondary connection pipe 130 is moved toward the left by the resilient force of the resilient member 145 disposed therebehind, and accordingly, the guide shaft 144 is moved upwardly by the first and the second slant projection parts 141, 143, as shown in FIGS. 4A and 4B.
  • the dust receptacle 300 can be separated from the cleaner body 200 without requiring the extra step of separation of the secondary connection pipe 130.
  • the guide shaft 144 is depressed by the end of cover 400 distally disposed from the axis, as shown in FIGS. 5 to 6B.
  • the secondary connection pipe 130 is pushed toward the right as shown in FIG. 5, and thus, is moved to the second position wherein the small-diameter part 130 thereof comes into tight contact with the dust receptacle 30 in the vicinity of the communication hole 310.
  • the outer lip of the small diameter part 132 is pressed against and engages the surface of the second gasket 160.
  • the secondary connection pipe 130 is again moved to the first position, as shown in FIG. 3.
  • the secondary connection pipe 130 is moved toward the hose connection pipe. Therefore, the secondary connection pipe 130 and the dust receptacle 300 are separated from each other by a predetermined distance. Accordingly, the dust receptacle 300 can be separated and removed from the cleaner body 200 without requiring the extra step of separation of the hose connection pipe. That is, the hose connection pipe does not have to be removed from the cleaner body for separation of the dust receptacle 300 from the cleaner body 200. Therefore, the vacuum cleaner becomes more convenient to use.
