Abstract
Exemplary foam-at-a-distance systems, refill units and foam generators are disclosed herein. An exemplary foam generator includes a body having an inlet for receiving air and an inlet for receiving liquid. The foam generator includes a plurality of baffles located within the body. A plurality of elongated spaces are formed at least in part by the baffles. The elongated spaces have a length that is greater than a width.
Claims17
A foam generator comprising:
- An elongated cylindrical body having an inlet located at a proximal end and an outlet located at a distal end;
- a fluid passage between the inlet and the outlet;
- the inlet configured to receive air from an air supply and liquid from a liquid supply;
- the body made of a first half and a second half;
- the first half and the second half made of a molded plastic;
- at least one of the first half and the second half including a plurality of baffles;
- a plurality of elongated spaces located between at least a portion of the plurality of baffles and the inside of the body when the first half and the second half are joined together;
- wherein the plurality of baffles cause the fluid passage between the inlet and the outlet to be a tortuous path.
