Abstract
A head unit for a surface-treatment apparatus is provided and includes a housing that includes a fluid inlet, a dispensation unit, and at least one baffle. The fluid inlet receives fluid from a fluid reservoir. The dispensation unit defines a dispensation chamber and an input port in fluid communication with each of the dispensation chamber and the fluid inlet. The at least one baffle is configured to direct the flow of fluid through the dispensation unit and out of the elongated dispensation outlet.
Claims20
A head unit for a surface-treatment apparatus, the head unit comprising:
- a housing comprising:
- a fluid inlet for receiving fluid from a fluid reservoir;
- a dispensation unit defining a dispensation chamber and an input port in fluid communication with each of the dispensation chamber and the fluid inlet, the dispensation unit comprising at least one wall that defines an elongated dispensation outlet for the fluid;
- and
- at least one baffle extending from said at least one wall at a height above said at least one wall such that the baffle extends into the dispensation chamber, said at least one baffle being located adjacent to the input port and extending away from the input port.
A head unit for a surface-treatment apparatus, the head unit comprising:
- a housing comprising:
- a fluid inlet for receiving fluid from a fluid reservoir;
- a dispensation unit defining a dispensation chamber in fluid communication with the fluid inlet, the dispensation unit defining an elongated dispensation outlet for the fluid;
- and
- at least one baffle disposed within and extending into the dispensation chamber, said at least one baffle being configured to direct the flow of fluid through the dispensation unit and out of the elongated dispensation outlet;
- a rotary member rotatably coupled with the housing and rotatable about a rotational axis, the rotary member being positioned adjacent the dispensation unit and configured to collect the fluid dispensed from the elongated dispensation outlet;
- and
- a collection container associated with the housing and configured to collect the fluid from the rotary member.
A surface-treatment apparatus comprising:
- a body;
- a motor coupled with the body;
- a fluid reservoir coupled with the body and configured to store fluid therein;
- and
- a head unit operably coupled with the motor, the head unit comprising:
- a housing that comprises:
- a fluid inlet for receiving fluid from the fluid reservoir;
- a dispensation unit defining a dispensation chamber in fluid communication with the fluid inlet, the dispensation unit defining an elongated dispensation outlet for the fluid;
- and
- at least one baffle disposed within and extending into the dispensation unit, said at least one baffle being configured to direct the flow of fluid through the dispensation unit and out of the elongated dispensation outlet;
- a rotary member rotatably coupled with the housing and operably coupled with the motor, the rotary member being rotatable about a rotational axis and positioned adjacent the elongated dispensation outlet, the rotary member being further configured to collect the fluid dispensed from the elongated dispensation outlet;
- and
- a collection container associated with the housing and configured to collect the dispensed fluid from the rotary member.
