members

156A and 156B, a connecting shaft 154, and a knob 152.

The mounting member 151 is built in the housing 110, and the sweeper 140 is mounted at the bottom of the mounting member 151. An elastic member 153 is interposed between the mounting member 151 and the housing 110. Such an elastic member ( 153 has one end coupled to the bottom surface of the mounting member 151 and the other end coupled to the top surface of the housing 110 to elastically support the mounting member 151. In addition, the top surface of the mounting member 151 will be described later. A mounting groove 151a is formed on which the protrusion 156a is mounted.

The

pressing members

156A and 156B press the mounting member 151 to allow the sweeper 140 to stand out of the housing 110. At this time, the sweeper 140 is projected to the outside of the housing 110 through the exit hole 111 formed on the bottom surface of the housing 110. The

pressing members

156A and 156B are formed in a cross-sectional shape, and a lower portion is provided with a protrusion 156a formed in a V shape. The protrusion 156a is seated in the mounting recess 151a of the mounting member 151 when the knob 152 is rotated to transmit continuous pressing force to the sweeper 140.

The

pressing members

156A and 156B are formed in plural, and in this embodiment, the first pressing member 156A disposed on the left side of the housing 110 and the second pressing member 156B disposed on the right side of the housing 110. ) Since the

pressing members

156A and 156B are provided at both sides of the sweeper 140, the

pressing members

156A and 156B may evenly push both sides of the sweeper 140 when the knob 152 is rotated. Accordingly, the sweeper 140 is evenly projected to the outside of the housing 110 without biasing to either side.

The side of the first pressing member 156A and the side of the second pressing member 156B are connected to the connecting shaft 154, and the first pressing member 156A is coupled to the knob 152. Therefore, when the knob 152 is rotated, the first pressing member 156A is rotated, the rotational force is transmitted to the second pressing member 156B through the connecting shaft 154, and the second pressing member 156B is also pressed first. It is rotated by the same angle in the same direction as the member 156A. Thus, even if only one knob 152 is operated, the left and right two

pressing members

156A and 156B can be rotated.

The connecting shaft 154 connects the first pressing member 156A and the second pressing member 156B. Thus, when the first pressing member 156A is rotated, the second pressing member 156B is also rotated at the same time. The connecting shaft 154 may be supported by the internal configuration of the housing 110 to be the center of rotation of the

pressing members

156A and 156B when the knob 152 is rotated. Therefore, when the user rotates the knob 152, the first pressing member 156A coupled to the knob 152 is rotated about the connecting shaft 154.

The knob 152 is rotatably installed in the housing 110, and is exposed to an upper surface of the housing 110 so that a user can easily rotate the knob. Knob 152 is coupled to the first pressing member 156A disposed on the left side of the housing 110, which is just one embodiment, and thus the second pressing member 156B disposed on the right side of the housing 110. Of course, it can be combined.

Hereinafter, the operating principle of the sweeper 140 coming out of the housing 110 in the suction head 100 for a vacuum cleaner according to an embodiment of the present invention will be described.

As shown in FIG. 7, when the user pushes the knob 152 in one direction while the sweeper 140 is inserted into the housing 110, the connecting shaft 154 is illustrated in FIG. 8. The knob 152 and the first pressing member 156A are rotated counterclockwise with the center of rotation as the center of rotation. At this time, the second pressing member 156A connected by the first pressing member 156A and the connecting shaft 154 also rotates counterclockwise. By the rotation, the protrusion 156a of the

pressing members

156A and 156B is seated in the seating groove 151a of the mounting member 151, and the sweeper 140 moves outwardly as the mounting member 151 moves downward. Protrudes out of the housing 110 through).

On the contrary, when the user wants to return the sweeper 140 to the inside of the housing 110 and the user presses the knob 152 in the other direction, the pressing member 156A is released from the seating groove 151a. , 156B rotates clockwise. At this time, since the force for pressing the mounting member 151 by the rotation of the pressing members (156A, 156B) disappears, the mounting member 151 is moved upward by the restoring force of the elastic member 153, the sweeper 140 Is returned to the interior of the housing 110.
