Abstract
A glass surface cleaning machine includes a supporting frame which has a fluid receiving chamber provided therein and includes a supporting arm frontwardly extended therefrom, a wiper blade transversely mounted on a front edge of the supporting arm of the supporting frame for wiping on a glass surface, and a vacuum device supported by the supporting frame. The vacuum device includes at least a fluid suction nozzle supported underneath the wiper blade and in communication with the fluid receiving chamber and an impeller to create a low pressure within the fluid receiving chamber with respect to the atmosphere pressure so as to create a sucking effect for removing fluid from the glass surface through the fluid suction nozzle and directing the fluid to deposit in the fluid receiving chamber.
Claims32
A glass surface cleaning machine, comprising:
- a supporting frame having a fluid receiving chamber provided therein and comprising a supporting arm frontwardly extended therefrom;
- a wiper blade transversely mounted on a front edge of said supporting arm of said supporting frame;
- and
- a vacuum device, supported by said supporting frame, comprising:
- at least a fluid suction nozzle communicating with said fluid receiving chamber and having a suction opening extended to position underneath said wiper blade;
- and
- a suction means for providing a sucking force at said suction opening of said fluid suction nozzle, wherein said suction means comprises a power source arranged to drive an impeller to create a low pressure within said fluid receiving chamber with respect to an atmosphere pressure so as to create said suction force at said suction opening adapted for removing any fluid existed along said wiper blade around said suction opening through said fluid suction nozzle and directing said fluid to deposit in said fluid receiving chamber, wherein said suction means further comprises an impeller housing supported on said supporting frame to receive said impeller, wherein said impeller housing has an air inlet communicating with said fluid receiving chamber and an air outlet arranged for discharging an air within said fluid receiving chamber through said impeller housing to create said suction force, wherein said suction means further comprises an air filter provided at said air inlet of said impeller housing for allowing said air within said fluid receiving chamber to pass into said impeller housing so as to prevent said fluid from entering thereinto.
