Cleaner

Abstract

A cleaner is disclosed. The cleaner includes a cleaner body, including a first connection passage for guiding external air thereinto, and a cleaning nozzle. The cleaning nozzle includes a case including a suction port and a second connection passage connected to the first connection passage to guide air sucked into the case through the suction port to the outside, a push button penetrating one surface of the case so as to be movable in the direction in which the push button is pressed, and a rotary member mounted to the outer surface of the second connection passage so as to be rotatable. The rotary member couples the first connection passage and the second connection passage to each other at normal times, and decouples the first connection passage and the second connection passage from each other when the rotary member is rotated along with movement of the push button.

What is claimed is: 
     
         1 . A cleaner comprising:
 a cleaner body comprising a first connection passage formed at an outer surface of the cleaner body to guide external air into the cleaner body; and   a cleaning nozzle configured to clean an area to be cleaned using a suction port formed therein for sucking air,   wherein the cleaning nozzle comprises:   a case comprising the suction port and a second connection passage for guiding air sucked into the case through the suction port to an outside, the second connection passage being connected to the first connection passage;   a push button penetrating one surface of the case so as to be movable in a direction in which the push button is pressed; and   a rotary member mounted to an outer surface of the second connection passage so as to be rotatable about a rotary shaft extending across the direction in which the push button is pressed, the rotary member being configured to couple the first connection passage and the second connection passage to each other at normal times and to decouple the first connection passage and the second connection passage from each other when the rotary member is rotated along with movement of the push button.   
     
     
         2 . The cleaner according to  claim 1 , wherein the rotary member comprises:
 a hinge portion comprising the rotary shaft, the hinge portion being hinged to the outer surface of the second connection passage;   a first arm portion extending in one direction from the hinge portion so as to be in contact with the push button; and   a second arm portion extending in an opposite direction from the hinge portion so as to couple the first connection passage and the second connection passage to each other, the second arm portion being configured to decouple the first connection passage and the second connection passage from each other when the first arm portion is pushed by the push button.   
     
     
         3 . The cleaner according to  claim 2 , wherein the second arm portion comprises a hook projection for coupling the first connection passage and the second connection passage to each other, the hook projection being configured to decouple the first connection passage and the second connection passage from each other when the first arm portion is pushed by the push button. 
     
     
         4 . The cleaner according to  claim 3 , wherein the first connection passage is inserted into the second connection passage,
 wherein the first connection passage has therein a hook hole into which the hook projection is inserted, and   wherein the second connection passage has therein a hook recess into which the hook projection is inserted.   
     
     
         5 . The cleaner according to  claim 2 , wherein the cleaning nozzle further comprises a cover mounted to the outer surface of the second connection passage to cover the hinge portion and the second arm portion. 
     
     
         6 . The cleaner according to  claim 5 , wherein the cleaning nozzle further comprises an elastic member for returning the rotary member to an original position of the rotary member, the elastic member being elastically supported by the second arm portion and the cover. 
     
     
         7 . The cleaner according to  claim 6 , wherein the elastic member is configured as a coil spring, and
 wherein the second arm portion comprises an insertion boss configured to be inserted into the coil spring.   
     
     
         8 . The cleaner according to  claim 2 , wherein the first arm portion is disposed at a rear position on the basis of the hinge portion,
 wherein the second arm portion is disposed at a front position on the basis of the hinge portion, and   wherein the push button is formed to be curved in a longitudinal direction thereof such that one end thereof that penetrates a side surface of the case is located further forward than an opposite end thereof that is in contact with the first arm portion.   
     
     
         9 . The cleaner according to  claim 8 , wherein the case comprises a guide protrusion formed therein to guide horizontal movement of the push button, and
 wherein the guide protrusion is formed such that a surface thereof that faces the push button is curved corresponding to a curvature of the push button.   
     
     
         10 . The cleaner according to  claim 2 , wherein the rotary shaft protrudes from one side of the hinge portion, and
 wherein the second connection passage has a hinge recess formed in the outer surface of the second connection passage, the hinge recess being configured to allow the rotary shaft to be inserted thereinto.   
     
     
         11 . The cleaner according to  claim 1 , wherein the cleaner body protrudes further outward than the first connection passage and the second connection passage, and
 wherein the cleaning nozzle protrudes further outward than the cleaner body.   
     
     
         12 . The cleaner according to  claim 1 , further comprising:
 a dust container detachably coupled to the cleaner body to store foreign substances therein; and   an adapter configured to interconnect the cleaner body and the cleaning nozzle and to allow the dust container to be seated thereon,   wherein the first connection passage is formed at the adapter.   
     
     
         13 . The cleaner according to  claim 1 , wherein the case comprises:
 an upper case comprising the second connection passage; and   a lower case coupled to the upper case, the lower case comprising the suction port that communicates with an internal space in the upper case and a through-hole that the push button penetrates in a horizontal direction.   
     
     
         14 . The cleaner according to  claim 1 , wherein the second connection passage is formed such that a distal end in a longitudinal direction thereof is located within the case.
