Suction Machine Comprising a Housing Made of Expanded Plastic Material

Abstract

The invention relates to a suction device for dental, medical or industrial purposes, comprising a suction system and a housing ( 12 ) in which the suction system ( 50 ) is accommodated. The suction device is characterized in that the housing ( 12 ) is composed of at least two housing shells ( 14, 16 ) that can be assembled and are manufactured from a foamable material, in that at least one of the housing shells ( 14, 16 ) has support surfaces that support and/or hold the components of the suction system ( 50 ) in the housing ( 12 ), and in that at least one of the housing shells ( 14, 16 ) forms at least one functional component of the suction system ( 50 ).

1 . A suction device for dental, medical or industrial purposes, the suction device comprising:
 a suction system; and   a housing in which the suction system is accommodated; wherein   the housing is composed of at least two housing shells that can be assembled and are manufactured from a foamable material, at least one of the housing shells has support surfaces that support and/or hold the components of the suction system in the housing, and at least one of the housing shells forms at least one functional component of the suction system.   
     
     
         2 . The suction device according to  claim 1 , wherein the suction system comprises at least one suction unit and/or at least one separating unit and/or at least one depositing unit. 
     
     
         3 . The suction device according to  claim 1 , wherein the foamable material is a plastic material. 
     
     
         4 . The suction device according to  claim 1 , wherein the housing shells are expanded from a plastic material. 
     
     
         5 . The suction device according to  claim 1 , wherein a functional component is an air-conducting duct, a supporting foot, a sound-insulating element, a vibration-decoupling element and/or a holding element for components of the suction device. 
     
     
         6 . The suction device according to  claim 5 , wherein a number of supporting feet are moulded onto at least one of the housing shells. 
     
     
         7 . The suction device according to  claim 1 , wherein there is moulded into at least one of the housing shells at least one accommodating region which serves to accommodate at least one component of the suction device. 
     
     
         8 . The suction device according to  claim 7 , wherein a component of the suction device is an electrical connecting element, a hose-connecting element, a control unit housing, an electrical line and/or a cable guide for lines. 
     
     
         9 . The suction device according  claim 1 , wherein support surfaces for a control unit, a fan unit, a separating unit and/or a driving unit are moulded into at least one of the housing shells. 
     
     
         10 . The suction device according to  claim 1 , wherein at least one opening, which serves as an air inlet opening or air outlet opening, is moulded into at least one of the housing shells. 
     
     
         11 . The suction device according to  claim 1 , wherein the housing is formed from two housing shells ( 14 ,  16 ). 
     
     
         12 . The suction device according to one  claim 1 , wherein the housing completely encapsulates the suction system. 
     
     
         13 . The suction device according to  claim 1 , wherein the suction unit is a radial suction machine. 
     
     
         14 . The suction device according to  claim 5 , wherein an air-conducting duct is routed round a region of the suction unit and/or of the separating unit. 
     
     
         15 . The suction device according to  claim 14 , wherein the air-conducting duct is routed into the region of the control unit. 
     
     
         16 . The suction device according to  claim 1 , wherein an air-conditioning duct is routed round a region of the suction unit and/or of the separating unit.
