  • the suction head further includes a manipulation unit projecting the sweeper out of the housing, and a projection hole through which the sweeper projects is formed in the bottom of the housing.
  • the manipulation unit includes a mounting member installed in the housing and to which the sweeper is mounted, a plurality of pressing members pressing the mounting member, a connector rod connecting the pressing members to each other, and a knob coupled with the pressing members and rotating the pressing members.
  • the suction head further includes an elastic member disposed between a lower side of the mounting member and an inner surface of the housing.
  • the knob is exposed over the upper side of the housing.
  • the pressing members rotate about the connector rod when the knob rotates.
  • the pressing members include V-shaped protrusions formed on the lower sides respectively and the mounting member has seat recesses, formed in an upper surface, on which the protrusions seat.
  • the pressing members include a first pressing member disposed at a left side of the housing and a second pressing member disposed at a right side of the housing, the connector rod connects a side of the first pressing member to a side of the second pressing member, and the knob is coupled with the first pressing member.
  • suction head of a vacuum cleaner of the present invention since suction holes are formed at the front and rear sides of the sweeper, a user may perform cleaning more easily and effectively while moving the suction head forward and backward.
  • the sweeper may be projected out of the housing whenever a user wants, various cleaning options may be selected.
  • FIG. 3 is a perspective view illustrating a suction head according to an embodiment of the present invention
  • FIG. 4 is a bottom view of the suction head of FIG. 3
  • FIG. 5 is a side sectional view taken along the line A-A of FIG. 3 .
  • a suction head 100 of a vacuum cleaner includes a housing 110 and a suction duct unit 120.
  • the housing 110 forms an outer appearance of the suction head 100 of a vacuum cleaner.
  • the housing 110 has a plurality of suction holes formed in the bottom such as a fist suction hole 112 and a second suction hole 114.
  • a fist suction hole 112 and a second suction hole 114.
  • the present invention is not limited thereto and three more suction holes may be formed.
  • the suction duct unit 120 is provided in the housing 110.
  • the suction duct unit 120 includes a main duct 122 and a first suction port 124 and a second suction port 126 which are branched from the main duct 122.
  • the main duct 122 communicates with a connector 130.
  • the connector 130 is connected to an extension pipe (not shown) communicated with a main body (not shown) of the vacuum cleaner.
  • the first suction port 124 communicates with a first suction hole 112 formed in the bottom of the housing 110 and the second suction port 126 communicates with a second suction hole 114 spaced apart from the first suction hole 112.
  • the first suction port 124 communicates with the outside of the housing 110 through the first suction hole 112 and the second suction port 126 communicates with the outside of the housing 110 through the second suction port 114.
  • the housing 110 includes a sweeper 140.
  • the sweeper 140 is disposed between the first suction hole 112 and the second suction hole 114. That is, with respect to the sweeper 140, the first suction hole 112 is disposed in front of the suction head 100 and the second suction hole 114 is disposed at the rear side of the suction head 100.
  • a suctioning force generated from the main body of the vacuum cleaner is transmitted to the suction head 100.
  • the suction head 100 suctions dust and foreign matter on a site to be cleaned such as a floor with the suctioning force.
  • FIG. 6 is a perspective view illustrating the suction head an upper portion of which is cut off.
  • FIG. 7 is a side sectional view taken along the line B-B of FIG. 3 .
  • FIG. 8 is a side sectional view illustrating a knob of FIG. 7 rotated in a direction.
  • the sweeper 140 is configured to project out of the housing 110 and the projection of the sweeper 140 is performed by a manipulation unit 150.
  • the manipulation unit 150 includes a mounting member 151, pressing members 156A and 156B, a connector rod 154, and a knob 152.
  • the mounting member 151 is installed in the housing 110 and mounted to the lower side of the sweeper 140.
  • An elastic member 153 is disposed between the mounting member 151 and the housing 110.
  • the elastic member 153 is configured such that an end is coupled to the lower surface of the mounting member 151 and the opposite end is coupled to the upper surface of the housing 110 to elastically support the mounting member 151.
  • the mounting member 151 has seat recesses 151a formed on the upper side and later-described protrusions 156a seat in the seat recesses 151 a.
  • the pressing members 156A and 156B press the mounting member 151 such that the sweeper 140 projects out of the housing 110. At this time, the sweeper 140 projects out of the housing 110 through a projection hole 111 formed in the bottom of the housing 110.
  • the pressing members 156A and 156B have a diamond-shaped section and have V-shaped protrusions 156a formed on the lower sides respectively. The protrusions 156a seat in the seat recesses 151a of the mounting member 151 when the knob 151 rotates and transmits a pressing force to the sweeper 140 continuously.
  • the connector rod 154 connects the first pressing member 156A to the second pressing member 156B. Due to this connection, when the first pressing member 156A rotates, the second pressing member 156B also rotates simultaneously.
  • the connector rod 154 may be supported by an internal structure of the housing 110 such that the connector rod 154 serves as a rotation center of the pressing members 156A and 156B when the knob 152 rotates. Thus, when a user rotates the knob 152, the first pressing member 156A coupled with the knob 152 rotates about the connector rod 154.
  • the knob 152 is installed to the housing 110 to rotate and is exposed over the upper surface of the housing 110 such that a user easily rotates the knob 152.
  • the knob 152 as an exemplary embodiment, is coupled with the first pressing member 156A disposed at the left side of the housing 110 and may be coupled with the second pressing member 156B disposed at the right side of the housing 110.
  • the knob 152 and the first pressing member 156A rotate about the connector rod 154.
  • the second pressing member 156B connected to the first pressing member 156A by the connector rod 154 also rotates in the counterclockwise direction. Rotation brings the protrusions 156a of the pressing members 156A and 156B to seat in the seat recesses 151a of the mounting member 151 and the sweeper 140 projects out of the housing 110 through the projection hole 111 by the downward movement of the mounting member 151.
