Handheld cleaner

Abstract

The disclosure relates to a handheld vacuum cleaner, comprising: a handle body having a first coupling part formed on one side in the longitudinal direction; a drive part body having a second coupling part formed on one side thereof so as to be detachably coupled to the first coupling part, a third coupling part formed on the other side, and a motor provided therein; and a filtration and discharge body having a first hollow part and a second hollow part, respectively formed at one side and the other side so as to communicate with each other, a dust receiving part formed between the first hollow part and the second hollow part so as to communicate with the first hollow part and the second hollow part, and a fourth coupling part formed on the inner surface of the first hollow part so as to be detachably coupled to the third coupling part. Therefore, each component can be completely disassembled and thus the volume can be greatly reduced, resulting in convenience in carrying or storage in a bag or the like, only the damaged components can be easily replaced at the time of partial component damage, thus reducing maintenance costs, and components of different capacity or shape can be replaced and used in combination depending on the purpose of use.

What is claimed is: 
     
         1 . A handheld vacuum cleaner, comprising:
 a handle body having a first coupling part formed on one side in the longitudinal direction;   a drive part body having a second coupling part formed on one side thereof so as to be detachably coupled to the first coupling part, a third coupling part formed on the other side, and a motor provided therein; and   a filtration and discharge body having a first hollow part and a second hollow part, respectively formed at one side and the other side so as to communicate with each other, a dust receiving part formed between the first hollow part and the second hollow part so as to communicate with the first hollow part and the second hollow part, and a fourth coupling part formed on the inner surface of the first hollow part so as to be detachably coupled to the third coupling part.   
     
     
         2 . The handheld vacuum cleaner according to  claim 1 , wherein the dust receiving part has opening portions formed at the front portion and the rear portion thereof and the front opening portion is configured to be opened or closed by an opening and closing cap which carries out hinge movement with respect to the filtration and discharge body. 
     
     
         3 . The handheld vacuum cleaner according to  claim 2 , wherein the dust receiving part is equipped with a dust housing and the dust housing has one opening portion, which is formed at one end of the dust housing so as to be opened or closed by the opening and closing cap of the filtration and discharge body, and the other opening portion, which is formed at the opposite side of the opening and closing cap so that a filtering member is inserted thereinto. 
     
     
         4 . The handheld vacuum cleaner according to  claim 3 , wherein the dust housing has a locking protrusion formed at a point of the edge of the opening portion thereof, the opening and closing cap has a hook formed on the outer circumference thereof so as to be coupled with the locking protrusion, and the dust housing has a detachment button formed on the outer surface thereof so as to push and detach the locking protrusion coupled with the hook from the hook. 
     
     
         5 . The handheld vacuum cleaner according to  claim 4 , wherein the opening and closing cap has a restoring force acting in a direction of opening the opening portion and the detachment button has a restoring force acting in a direction away from the locking protrusion. 
     
     
         6 . The handheld vacuum cleaner according to  claim 3 , wherein the filtering member has a withdrawal stem formed in the center thereof. 
     
     
         7 . The handheld vacuum cleaner according to  claim 3 , wherein the filtration and discharge body has a valve installed therein at the other side where the second hollow part is formed so that the valve opens or closes the passage between the space in the dust receiving part and the second hollow part. 
     
     
         8 . The handheld vacuum cleaner according to  claim 7 , wherein the valve is made of an arcuately curved surface, and the front end thereof is in contact with the end of the second hollow part at the outlet side thereof so as to maintain a closed state. 
     
     
         9 . The handheld vacuum cleaner according to  claim 1 , wherein the handle body is obliquely extended downwards based on the first coupling part. 
     
     
         10 . The handheld vacuum cleaner according to  claim 1 , wherein when the first coupling part is viewed from the front, the first coupling part has a male locking protrusion formed on one side based on the center in the width direction and a connector part formed with a female connector terminal on the other side. 
     
     
         11 . The handheld vacuum cleaner according to  claim 10 , wherein when viewed from the bottom, the other side where the connector part is formed and the one side where the male locking protrusion is formed have a stepped difference therebetween, the male locking protrusion is formed to protrude from the front end surface of the one side, and the protruding length thereof is formed to be shorter than the protruding length of the connector part. 
     
     
         12 . The handheld vacuum cleaner according to  claim 1 , wherein a suction body is additionally provided so as to be detachably coupled to the second hollow part of the filtration and discharge body, and the suction body has a connection duct formed at one side and having a third one-touch fastening button and a current-carrying part to correspond and be connected to the second hollow part.
