         2 . The cleaning appliance of  claim 1 , wherein the rotary shaft is inclined at an angle of 30° to 60° toward a direction where the handle is located based on a straight line passing through the center of gravity of the particle separator. 
     
     
         3 . The cleaning appliance of  claim 1 , wherein the rotary shaft is inclined at an angle of 45° toward a direction where the handle is located based on a straight line passing through the center of gravity of the particle separator. 
     
     
         4 . The cleaning appliance of  claim 1 , wherein the housing includes:
 a first housing providing a space in which the particle separator is stored, provided with the intake unit on a circumferential surface;   a second housing providing a space in which the fan is stored, inclined from an upper end of the first housing toward a direction where the handle is located;   a first cover provided to open or close a lower surface of the first housing; and   a second cover provided to open or close an upper surface of the second housing and provided with the exhaust unit.   
     
     
         5 . The cleaning appliance of  claim 1 , wherein the angle of the second housing inclined toward the handle based on the vertical line passing through the center of gravity of the particle separator is set to be equal to the angle of the rotary shaft inclined toward the handle. 
     
     
         6 . The cleaning appliance of  claim 5 , wherein the handle includes:
 a bar shaped handle body extended from the battery housing toward the second housing; and   a bar shaped connection body connecting the handle body with a circumferential surface of the second housing.   
     
     
         7 . The cleaning appliance of  claim 5 , wherein a length of the battery from the circumferential surface of the first housing toward a direction headed for the handle is set to be longer than a length of the battery toward a height direction of the first housing and a length of the battery toward a diameter direction of the first housing. 
     
     
         8 . The cleaning appliance of  claim 5 , wherein the center of gravity of the fan is located between the center of gravity of the particle separator and the center of gravity of the battery, and the center of gravity of the battery is located between the center of gravity of the fan and the center of gravity of the handle. 
     
     
         9 . The cleaning appliance of  claim 8 , wherein the center of gravity of the fan is located above a reference line passing through the center of the intake unit, the center of gravity of the particle separator and the center of gravity of the battery are located below the reference line, and the center of gravity of the handle is located on the reference line or below the reference line. 
     
     
         10 . The cleaning appliance of  claim 9 , wherein the center of gravity of the fan, the center of gravity of the particle separator, the center of gravity of the battery and the center of gravity of the handle are all located on a single vertical line that includes the reference line. 
     
     
         11 . The cleaning appliance of  claim 4 , wherein the particle separator includes:
 a partition provided inside the housing, partitioning the first housing and the second housing from each other;   a partition through hole provided to pass through the partition;   chamber bodies provided in a hollow cylinder shape, having one end fixed to the partition and the other end which is in contact with the first cover, and partitioning an inner space of the first housing into a first chamber communicated with the intake unit and a second chamber communicated with the partition through hole;   a body partition partitioning an inner space of the second chamber into a first space communicated with the partition through hole and a second space which is not communicated with the partition through hole;   a communication hole provided to pass through the chamber bodies to communicate the first space with the first chamber;   a path body provided in a pipe surrounding the partition through hole, having one end fixed to the partition and the other end communicated with the second space by passing through the body partition;   a discharge pipe provided as a pipe extended from the partition through hole toward the body partition and provided inside the path body;   an inlet provided to pass through the path body, guiding the air supplied to the communication hole to the inside the path body; and   an air flow forming portion provided in a screw shape between the discharge pipe and the path body, rotating the air entering the inlet inside the path body.   
     
     
         12 . The cleaning appliance of  claim 11 , wherein the fan includes:
 a case provided in the second housing, storing the impeller therein;   a case intake hole provided on one surface of the case headed for the partition through hole to allow the air to enter the inside of the case; and   a case exhaust hole provided on one surface of the case headed for the exhaust unit to discharge the air inside the case to the outside.   
     
     
         13 . The cleaning appliance of  claim 12 , further comprising:
 a first filter located between the partition through hole and the case intake hole, filtering the air; and   a second filter located between the case exhaust hole and the exhaust unit to filter the air,   wherein the second filter is provided to filter particles smaller than those filtered by the first filter.
