Abstract
Provided is a dual venturi. The dual venturi includes a housing including a housing body opened in a reference direction so that a gas or air flows, an inner partition wall through which an inner space of the housing body is divided into a first conduit and a second conduit, and a gas providing part provided with a first gas conduit passing through the first conduit to allow the first conduit to communicate with the outside therein and a second gas conduit configured to allow the second conduit to communicate with the outside, an opening/closing unit disposed in the inner space to open and close the first gas conduit and the second conduit, and a driver connected to the opening/closing unit to provide driving force to the opening/closing unit.
Claims14
A dual venturi comprising:
- a housing comprising a housing body opened in a reference direction so that a gas or air flows, an inner partition wall through which an inner space of the housing body is divided into a first conduit and a second conduit, and a gas providing part provided with a first gas conduit passing through the first conduit to allow the first conduit to communicate with the outside therein and a second gas conduit configured to allow the second conduit to communicate with the outside;
- an opening/closing unit disposed in the inner space of the housing body to open and close the second gas conduit and the second conduit;
- and
- a driver connected to the opening/closing unit to provide driving force to the opening/closing unit,
- wherein the second gas conduit comprises:
- a (second-1)th gas conduit configured to communicate with the outside and opened and closed by the opening/closing unit;
- and
- a (second-2)th gas conduit configured to allow the (second-1)th gas conduit to communicate with the second conduit.

- an opening/closing unit disposed in the inner space of the housing body to open and close the second gas conduit and the second conduit;
- and
- a driver connected to the opening/closing unit the cam assembly to provide driving force to the opening/closing unit,
- wherein the second gas conduit comprises:
- a (second-1)th gas conduit configured to communicate with the outside and opened and closed by the opening/closing unit;
- and
- a (second-2)th gas conduit configured to allow the (second-1)th gas conduit to communicate with the second conduit,
- the second gas conduit is configured to communicate with one region of the second conduit adjacent to the cam assembly, and
- the opening/closing unit moves in a longitudinal direction of the (second-1)th gas conduit inside the (second-1)th gas conduit by the driver to control a flow of gas introduced from the outside to the (second-1)th gas conduit.
