Dust collecting device

Abstract

A dust collecting device comprising a dust collector comprising a port; and a dust collecting mattress comprising a mattress cover, a mattress working face, and a dust exhaust; the port is connected to the dust exhaust via a dust pipe; the mattress working face is formed with a plurality of small holes connected to the dust exhaust; a plurality of stiffening ribs is disposed between the mattress cover and the mattress working face, and a clearance space is formed between the stiffening ribs; the stiffening ribs are concave in shape; and a raised hollow ring is formed along the outer edge of the dust collecting mattress.

1 . A dust collecting device, comprising
 a dust collector ( 1 ) comprising a port ( 10 ); and   a dust collecting mattress ( 2 ) comprising a mattress cover ( 3 ), a mattress working face ( 4 ), and a dust exhaust ( 6 );   
     wherein
 said port ( 10 ) is connected to said dust exhaust ( 6 ) via a dust pipe ( 5 ); 
 said mattress working face ( 4 ) is formed with a plurality of small holes ( 9 ) connected to said dust exhaust ( 6 ) via a plurality of ducts, each said duct forming a shortest line between said small hole and said dust exhaust, whereby allowing dust or dirt particles to drop down to said dust exhaust ( 6 ) under the influence of gravity without the need for a suction device. 
 
   
   
       2 . The device of  claim 1 , wherein a plurality of stiffening ribs ( 7 ) is disposed between said mattress cover ( 3 ) and said mattress working face ( 4 ), and a clearance space is formed between said stiffening ribs ( 7 ). 
   
   
       3 . The device of  claim 2 , wherein said stiffening ribs ( 7 ) are concave in shape. 
   
   
       4 . The device of  claim 1 , wherein a raised ring ( 8 ) is formed along the outer edge of said dust collecting mattress ( 2 ), and said raised ring is hollow. 
   
   
       5 . The device of  claim 4 , wherein said mattress working face ( 4 ) is of an irregularly-raised shape whereby providing good anti skid performance. 
   
   
       6 . The device of  claim 5 , wherein said raised ring ( 8 ) is adapted to store fragrance and simultaneously to improve said anti-skid performance of the device. 
   
   
       7 . A dust collecting device, comprising
 a dust collector ( 1 ) comprising a port ( 10 );   a dust collecting mattress ( 2 ) comprising a mattress cover ( 3 ), a mattress working face ( 4 ) with a plurality of small holes ( 9 ), and a dust exhaust ( 6 ); and   not comprising a suction device connected to said dust exhaust ( 6 ), wherein   said port ( 10 ) is connected to said dust exhaust ( 6 ) via a dust pipe ( 5 ); and   each said small hole ( 9 ) is connected to said dust exhaust ( 6 ) by a passage oriented at an acute angle with respect to the horizontal, whereby allowing dust or dirt particles to drop down to said dust exhaust ( 6 ) under the influence of gravity only.   
   
   
       8 . The device of  claim 7 , wherein a plurality of stiffening ribs ( 7 ) is disposed between said mattress cover ( 3 ) and said mattress working face ( 4 ), and a clearance space is formed between said stiffening ribs ( 7 ). 
   
   
       9 . The device of  claim 8 , wherein said stiffening ribs ( 7 ) are concave in shape. 
   
   
       10 . The device of  claim 7 , wherein a raised ring ( 8 ) is formed along the outer edge of said dust collecting mattress ( 2 ), and said raised ring is hollow. 
   
   
       11 . The device of  claim 10 , wherein said mattress working face ( 4 ) is of an irregularly-raised shape whereby providing good anti skid performance. 
   
   
       12 . The device of  claim 11 , wherein said raised ring ( 8 ) is adapted to store fragrance and simultaneously to improve said anti-skid performance of the device. 
   
   
       13 . A dust collecting device, comprising
 a dust collector ( 1 ) comprising a port ( 10 );   a dust collecting mattress ( 2 ) comprising a mattress cover ( 3 ), a mattress working face ( 4 ) with a plurality of small holes ( 9 ), and a single central dust exhaust ( 6 ) for all said small holes ( 9 ); and   not comprising a suction device connected to said dust exhaust ( 6 ), wherein   said port ( 10 ) is connected to said dust exhaust ( 6 ) via a dust pipe ( 5 ); and   each said small hole ( 9 ) is connected to said dust exhaust ( 6 ) by a passage oriented at an acute angle with respect to the horizontal, whereby allowing dust or dirt particles to drop down to said dust exhaust ( 6 ) under the influence of gravity only.   
   
   
       14 . The device of  claim 13 , wherein a plurality of stiffening ribs ( 7 ) is disposed between said mattress cover ( 3 ) and said mattress working face ( 4 ), and a clearance space is formed between said stiffening ribs ( 7 ). 
   
   
       15 . The device of  claim 14 , wherein said stiffening ribs ( 7 ) are concave in shape. 
   
   
       16 . The device of  claim 13 , wherein a raised ring ( 8 ) is formed along the outer edge of said dust collecting mattress ( 2 ), and said raised ring is hollow. 
   
   
       17 . The device of  claim 16 , wherein said mattress working face ( 4 ) is of an irregularly-raised shape whereby providing good anti skid performance. 
   
   
       18 . The device of  claim 17 , wherein said raised ring ( 8 ) is adapted to store fragrance and simultaneously to improve said anti-skid performance of the device.
