- the liquid supply tube 300 is provided to communicate the nicotine liquid storage unit 200 and the liquid inlet 124 of the central pipe.
- a nicotine inhaler when trying to inhale liquid nicotine into the human body, it is important to finely aerosolize the liquid nicotine to facilitate lung inhalation.
- the propellant is included in the storage unit 200 together with the nicotine liquid phase, since the nicotine liquid phase is discharged very quickly, it enters the mouth immediately after inhalation and large droplets strike the larynx and airway, thereby exhibiting negative sensory characteristics. Therefore, it is necessary to aerosolize the nicotine liquid more quickly and more finely.
- the nicotine inhaler of the present invention is aerosolized more finely immediately after the nicotine liquid phase is discharged due to the special structure as described above.
- the liquid aerosolization mechanism of the nicotine inhaler of the present invention is described as follows.
- a user inhales air through the suction part 600 of the nicotine inhaler shown in FIG. 1
- the pressure of the central pipe part 122 of the venturi pipe 120 is lowered according to Bernoulli's principle. Therefore, due to this pressure difference, the nicotine liquid phase 220 accommodated in the nicotine liquid storage unit 200 is discharged in a liquid state through the liquid supply tube 300 to the liquid inlet 124 of the central pipe part 122 (Fig. 5 (a)), while the propellant is vaporized by the pressure difference at the same time, bubbles are generated (Fig. 5 (b)). Thereafter, as the bubbles grow, the liquid film between the bubbles is broken (Fig. 5(c)), and the nicotine liquid phase is aerosolized (Fig. 5(d)). At this time, the larger the pressure difference, the faster the bubbles grow and the faster the liquid film is broken, thereby improving the aerosol generation efficiency.
- the end of the outlet pipe part 123 extends to the suction port 500 at the end of the housing 110 to form the suction part 600, and the outlet pipe part may have a shape in which the pipe diameter gradually expands from the end of the central pipe portion 122 to the inlet of the end of the housing.
- the end of the inlet pipe portion 121 may extend to the air inlet 400 at the end of the housing 110 to form an air inlet.
- the length L2 of the outlet tube 123 is preferably formed longer than the length L1 of the inlet tube 121 . This is because, since the aerosol is further atomized while flying, it is effective for atomization to make the outlet pipe part 123 long.
- the inlet pipe portion 121 includes a first taper portion tapered toward the central pipe portion 122, and the outlet pipe portion 123 is It includes a second taper portion tapering toward the pipe portion 122, and as shown in FIG. 6, the angle formed by the first taper portion and the central axis of the venturi tube 120 (FIG. 6, a) is the second taper It is preferable that the angle greater than the angle (Fig. 6, b) made with the central axis of the venturi tube.
- the length of the outlet pipe portion 123 is formed longer than the length of the inlet pipe portion 121, and it is advantageous to form the size of the air inlet port 400 large, so under these conditions, the first taper This is because the negative angle is inevitably greater than the angle of the second taper portion.
- the diameter of the inlet pipe part 121 is large.
- the central pipe portion 122 may have a diameter of 0.5 mm to 1 mm, more preferably 0.6 to 0.8 mm, and a length of 1 mm to 5 mm.
- the central pipe portion 122 must have a diameter and length capable of forming an appropriate negative pressure. If the diameter is too narrow and the length is too long, the flow rate decreases due to wall friction resistance and pressure loss occurs, so that the negative pressure is not sufficiently formed. not desirable because Therefore, it is preferable that the diameter and length are formed within the above range.
- the diameter of the central pipe part 122 should be at least 0.5 mm in order to ensure an appropriate suction flow rate in the suction part. This is because, when the diameter is 5 mm, a mixture of 20 ml of air and nicotine liquid aerosol can be inhaled in 2 seconds even with the smallest breath. In addition, when it exceeds 1 mm, sufficient negative pressure is not formed in the central pipe part, which is disadvantageous for aerosolization.
- Figure 7 shows the flow rate of the suction unit according to the diameter and length of the central pipe portion 122 as described above.
- the length of the central pipe portion 122 should be greater than 1 mm in consideration of the arrangement and size of the liquid inlet 124, and should be less than 5 mm because appropriate negative pressure should be formed.

- the arrangement of the nicotine liquid storage unit 200 makes it possible to manufacture the nicotine inhaler in a compact structure.
- the liquid supply tube 300 may be provided with a crimping unit 310 that locks the liquid supply tube during non-suction and opens the liquid supply tube during suction.
- the crimping part can be opened by this pressure difference since the pressure of the central pipe part of the Veturi pipe is lowered when the user sucks in the inhaler.
- the crimping unit may include, for example, a sensor that senses suction pressure when the inherer is sucked in and a solenoid valve that opens the liquid supply tube according to the sensing result when the sensor senses the suction state.
- the solenoid valve keeps the liquid supply tube closed during non-suction.
- the crimping unit may be operated manually. That is, before the user sucks in the inhaler, the crimping rod (FIG. 11, 311) supported by the spring 312 and crimping the liquid supply tube is pressed to open the liquid supply tube (FIG. 11 (b) )), and after the suction is finished, the pressure applied to the crimping rod is released to return the liquid supply tube to the closed state (FIG. 11 (a)).
- the crimping part may be formed in a known shape.
- the structure of the nicotine inhaler of the present invention may include additional components for the application of the crimping member.

It includes a membrane, and a pivot may be provided at one end of the membrane toward the air inlet 400. Accordingly, when the pressure between the membrane and the inner wall of the housing decreases when the inhaler is sucked in, the membrane rotates around the pivot and moves toward the inner wall of the housing.
- a jaw capable of pressurizing the liquid supply tube 300 may be provided at the lower end of the membrane.
- the membrane may be formed in a structure that receives downward force by an elastic member such as a spring when the inhaler is not inhaled, and by this force, the jaw presses the liquid supply tube to block the flow of the nicotine liquid phase.
- an elastic member such as a spring
- the jaw presses the liquid supply tube to block the flow of the nicotine liquid phase.
- the membrane rises due to the lowered pressure between the membrane and the inner wall of the housing, thereby lifting the tank, thereby releasing the pressure on the liquid supply tube and supplying the nicotine liquid phase.
- the liquid supply tube may be made of a flexible material to enable the operation of the crimping means.
- the diameter of the liquid phase injection port smaller than the diameter of the liquid phase supply tube for opening the crimping element by negative pressure.

- the scent diffusing element may assist inhalation by adding scent through the introduced air.
- the scent diffusing elements include solid scents, scents contained in porous substrates, scented sheets, scented capsules, and the like.
- the nicotine liquid phase may further include a propellant together with the nicotine liquid, and as the propellant, those known in the art may be used, for example, HFA-134a, CFC, etc. can be used
- the propellant serves to easily supply the nicotine liquid by forming pressure inside the nicotine liquid storage container, and serves to generate bubbles when the nicotine liquid is discharged into the venturi tube.
- the liquid phase supplied in this way moves to the suction port 500 via the outlet pipe part 123 on the fast air flow.
- bubbles are rapidly and rapidly formed in the nicotine liquid phase due to the negative pressure, the liquid film becomes thinner, and the liquid film is rapidly broken to form an aerosol.
- the nicotine aerosol flies in the direction of the inlet 500, it is atomized by friction between the air and the liquid phase and surface tension characteristics of the liquid phase due to a high speed difference between the air and liquid phases, thereby forming a finer aerosol of several ⁇ m.
- the nicotine inhaler of the present invention is opened at a lower negative pressure compared to the conventional nicotine inhaler that is opened to atmospheric pressure, more bubbles are formed in the liquid phase and grow faster, and thus the liquid film is broken faster. Therefore, nicotine liquid phase is more finely atomized by this mechanism.
- the particle size and particle size distribution of the aerosol inhaled through the mouth were measured with a particle size measuring device (product name: Spraytech, manufacturer name: Malvern), and the results are shown in FIGS. 12 and 13 was As confirmed in the figures, the nicotine inhaler of the present invention exhibits excellent aerosolization properties.
