- the opening and closing member is caused by the elastic force of the elastic member 540. 534 maintains a shielding state of the suction hole 512. At this time, in a state in which the opening and closing member 534 shields the suction hole 512, the opening and closing member 534 is in close contact with one surface of the dust container 510 in which the suction hole 512 is formed.
- the opening and closing member 534 connected to the pressing button 531 moves in the same direction as the moving direction of the pressing button 531. Then, the suction hole 531 is opened so that the inside of the dust container 510 and the outside of the dust container 510 communicate with each other.
- a first flow path 552 is formed between the inner wall of the dust container 510 and the opening / closing member 534 to allow the sucked air to flow.
- a series of flow paths through which air sucked into the dust container 510 passes through the through hole 536 to the cyclone part 521 may be referred to as a second flow path 554.
- the opening / closing member 534 may be described as defining a part of the second flow path 554.
- the second flow path 554 may be formed at the center of the dust container 510, and the first flow path 552 may be formed outside the second flow path 554.
- the dust discharged between the cyclone portion 521 and the dust container 510 is discharged by air. It moves to the (523) side, and is finally sucked into the cyclone portion 521 through the dust discharge portion 523.
- the cyclone flow inside the cyclone part 521 is momentarily broken, and the dust stored in the dust container together with the air is divided into the cyclone part ( 521 is sucked into the inside to allow dust to be discharged from the dust container 510.
- the dust and air of the dust container 510 sucked into the cyclone part 521 are discharged through the air discharge part 526 and then moved to the connection pipe 30.
- the pressing button 531 when the force for pressing the pressing button 531 is removed, the pressing button 531 is returned to the original position by the elastic member 540, the opening and closing member 534 is the suction hole ( 512).
- FIG. 18 is a cross-sectional view showing the configuration and operation of the nozzle according to the fifth embodiment of the present invention.
- a plurality of protrusion members 612 tapping the surface to be cleaned when the vibration member 610 vibrates is provided below the vibration member 610 according to the fifth embodiment of the present invention.
- the protrusion member 612 protrudes downward from the bottom surface of the vibration member 610.
- a plurality of suction holes 613 are formed in the protrusion member 612 to suck in dust separated from the surface to be cleaned by the protrusion member 612.
- the vibrating member 610 when the vibrating member 610 vibrates, the vibrating member 610 hits the surface to be cleaned, for example, bedding, so that dust on the surface to be cleaned is shaken off the surface to be cleaned. In addition, some of the dust is sucked into the nozzle body 10 through the suction hole 613, and another part is sucked into the nozzle body 10 through the suction unit 19. .
- the nozzle body 10 includes a first suction passage 630 for moving air and dust sucked from the main suction unit 18 to the connection pipe 40, and a movement to the accommodation space 19.
- a second suction passage 640 is included to allow dust and air to move to the first suction passage 630.
- the vibration member 610 may be described as being located on the second suction passage. In addition, the vibration member 610 may be described as forming a part of the second suction passage.
- air and dust moved to the second suction channel 640 may be combined with the first suction channel 30.
- the vibrating member 610 since some of the dust separated from the surface to be cleaned by the vibrating member 610 is sucked directly into the second suction flow path, the scattering of dust can be reduced, and the dust flows into the two suction flow paths. Since it can be sucked, there is an advantage that can be sucked smoothly.
- the dust is separated from the surface to be cleaned by the vibration member and can be easily sucked into the nozzle of the cleaner, the industrial applicability is remarkable.
