Abstract

The present invention provides a nicotine inhaler including: a body including a housing and a venturi tube disposed in the housing; a liquid nicotine storage; and a liquid supplying tube that supplies the liquid nicotine into the venturi tube, wherein the venturi tube includes an inlet pipe section communicating with an air intake port at one end of the housing, a central pipe section having a liquid injection hole on a wall thereof, and an outlet pipe section communicating with an inhalation port at the other end of the housing, and the liquid supplying tube is disposed to communicate with the liquid nicotine storage and the liquid injection hole of the central pipe section.

First claim

The invention claimed is:

1 . A nicotine inhaler comprising:
a body including a housing and a venturi tube disposed in the housing; a liquid nicotine storage; a liquid supplying tube configured to supply liquid nicotine from the liquid nicotine storage into the venturi tube, wherein the venturi tube includes an inlet pipe section communicating with an air intake port at one end of the housing, a central pipe section having a liquid injection hole on a wall thereof, and an outlet pipe section communicating with an inhalation port at the other end of the housing; and a heating element disposed between the air intake port and the inlet pipe section of the venturi tube, wherein the liquid supplying tube is disposed to communicate with the liquid nicotine storage and the liquid injection hole of the central pipe section, the liquid supplying tube comprises a crimping unit configured to lock the liquid supplying tube when the nicotine inhaler is not being inhaled and open the liquid supplying tube when the inhaler is being inhaled, and a diameter of the liquid injection hole is smaller than a diameter of the liquid supplying tube.

2 . The nicotine inhaler of claim 1 , wherein an end of the outlet pipe section is extended to the inhalation port at the other end of the housing to form an inhalation part, and the outlet pipe section has a form in which a pipe diameter is gradually enlarged from an end of the central pipe section to the inhalation port at the other end of the housing.

3 . The nicotine inhaler of claim 2 , wherein the end of an inlet pipe section is extended to the air intake port at the one end of the housing to form an air intake section.

4 . The nicotine inhaler of claim 3 , wherein the outlet pipe section has a longer length than the inlet pipe section.

5 . The nicotine inhaler of claim 4 , wherein the inlet pipe section of the venturi tube includes a first tapered portion tapered toward the central pipe section, and the outlet pipe section thereof includes a second tapered portion tapered toward the central pipe section, and
an angle formed by the first tapered portion and a center axis of the venturi tube is larger than an angle formed by the second tapered portion and the center axis of the venturi tube.

6 . The nicotine inhaler of claim 1 , wherein the central pipe section has a diameter of 0.5 mm to 1 mm and a length of 1 mm to 5 mm.

7 . The nicotine inhaler of claim 1 , wherein the liquid nicotine storage is located in a space between the housing and an inner wall of the body including a part or the whole of the venturi tube.

8 . The nicotine inhaler of claim 7 , wherein the liquid nicotine storage includes an annular container, and the annular container is provided in a form surrounding an outer circumferential surface of the inner wall of the body.

9 . The nicotine inhaler of claim 1 , wherein the diameter of the liquid injection hole is 0.1 mm to 0.5 mm.
