Description

TECHNICAL FIELD

The present invention relates to a nicotine inhaler, specifically, a nicotine inhaler that can adjust smoky and smokeless modes.

The present application claims priority based on Korean Patent Application No. 10-2021-0102131 filed on Aug. 3, 2021, the entire contents of which are incorporated herein by reference.

BACKGROUND ART

A method of delivering nicotine to the lungs in an aerosol type through an inhaler is an attractive means for delivering nicotine. In this case, the size of the aerosol is a very important factor for satisfaction of smoking. This is because when aerosol of large particles is inhaled, large drops hit against the occiput or the respiratory tract, thereby transmitting a negative feeling. That is, the smaller the particle size of nicotine aerosol, the more the nicotine is smoothly inhaled and the deeper the nicotine permeates into the lungs, whereby satisfaction of smokers can be improved.

In addition to the particle size of nicotine aerosol, as a factor that determines satisfaction of smokers who use an inhaler, whether an abundant amount of visible smoke is generated may be one of important factors that determine satisfaction of smokers, depending on smokers, in that common inhalers supply a predetermined amount of liquid nicotine through each puff and generate invisible aerosol when the smoker inhales and exhales.

However, conventional nicotine inhalers give the smokers a feeling of satisfaction by nicotine supplied in a predetermined amount through liquid-state aerosol, but do not generate an abundant amount of smoke that can be visually seen or cannot adjust the amount of smoke, so smokers have pointed out that satisfaction of smoking is low.

In order to solve this problem, it is required to research and develop a nicotine inhaler that enables the smokers to adjust an abundant amount of smoke that can be visually seen in person.

Further, as compared with when the second liquid storage part 300 is positioned in the opening 120, there is an advantage that it is easy to secure a channel for air flowing into the opening 120.

In an embodiment of the present invention, as shown in FIGS. 1 and 3, the second liquid storage part 300 may further include a liquid absorber 410 in which the smoke generating liquid is impregnated.

In an embodiment of the present invention, the liquid absorber 410 may be selected from a group consisting of paper, cotton, a porous bead, and a combination thereof, but may be any one publicly known in the art as long as it can easily absorb a liquid before vaporizing the smoke generating liquid. For example, the liquid absorber may be a roll of wrinkled paper, a lump of cotton, or a wick made of a porous bead, but is not particularly limited thereto.

In an embodiment of the present invention, as shown in FIGS. 1 and 3, a heating element 400 that generates smoke by heating the smoke generating liquid is included. The heating element 400 may be a unit that applies heat to a smoke generating liquid to generate smoke. The heating element 400 may be a heat source based on a chemical reaction, a thermoelectric element, a conductive metal heating element, a ceramic heating element, or the like, but is not particularly limited thereto as long as it can apply heat. For example, the heating element 400 may be a heater including conductive metal having a straight, curved, spiral, or zigzag pattern.

In an embodiment of the present invention, the heating element 400 may be positioned on the surface of or inside the liquid absorber 410 to heat the smoke generating liquid. Whether to dispose the heating element 400 on the surface of the liquid absorber 410 or how deep the heating element 400 is in-mold in the liquid absorber 410 may be designed in accordance with whether a burnt taste is expressed or an overheating phenomenon occurs.

In an embodiment of the present invention, the nicotine inhaler further include: a liquid supplying tube 210 that supplies a liquid nicotine into the housing 110 from the first liquid storage part 200; and a liquid injection port 211 connected with the liquid supplying tube 210, and the heating element 400 may be disposed at a position closer to the opening 120 than the liquid injection port 211. When the heating element 400 generating smoke by heating the smoke generating liquid of the liquid absorber 410 is disposed closer to the opening 120 through which air is introduced than the liquid injection port 211, there is an effect that contact with air increases, so more smoke can be generated and the user can conveniently replace a cartridge.

In an embodiment of the present invention, as shown in FIGS. 1 and 3, a crimping unit 220 that closes the liquid supplying tube in non-inhaling and opens the liquid supplying tube in inhaling may be disposed on the liquid supplying tube 210. The crimping unit 220 may be a publicly known type. For example, the clamping member disclosed in Korean Patent No. 10-1734932 may be applied. In this case, in order to apply the crimping member, the structure of the nicotine inhaler of the present invention may include an additional component. For example, one suction port communicating with the space between the housing and the inner surface of the body may be further formed at the suction port, and the crimping unit 220 may further have a part that can remove the pressure that is applied to the liquid supplying tube by the crimping unit by operating in inhaling through the suction port.

In an embodiment of the present invention, as shown in FIGS. 1 to 3, the nicotine inhaler further includes a switch 50 disposed on the outer surface of the body. The switch 500, which is a component that adjusts the amount of heat that is supplied to the heating element 400, is not particularly limited in the shape and size as long as the user can easily turn on/off the switch even during smoking and can adjust the amount of smoke.

In an embodiment of the present invention, the switch 500 may be a component that controls start and end in generating smoke and the amount of smoke in accordance with the preference of the smoker by adjusting step by step the amount of heat that is supplied to the heating element 400. For example, the switch may be a button-type switch capable of selecting smoky and smokeless modes, or may be configured in a type capable of selectively adjusting the amount of smoke to be high, medium, or low even in a smoky mode by including a plurality of buttons. Further, even in one step selected through the switch, the degree of flow that is generated around the wick varies according to the inhaling amount of the user and in this case, an evaporation amount according to a convective effect also varies, so the amount of generated smoke can be adjusted.

In an embodiment of the present invention, the housing 110 includes a venturi tube therein, wherein the venturi tube includes: an inlet tube section communicating with an opening at one end of the housing; a center tube section having a liquid injection port in the inner surface; and an outlet tube section communicating with the suction port at the other end of the housing, and the first liquid storage part 200 may communicate with the liquid injection port 211 of the center tube section through the liquid supplying tube 210. When the venturi tube is included, a liquid nicotine may be quickly changed into micro-aerosol to be easily inhaled into the lungs. Specifically, a liquid nicotine may be micro-aerosolized using a pressure difference in an air channel widened again after the liquid nicotine has passed a rapidly narrowed section from a wide section.

In an embodiment of the present invention, the outlet tube section may have a length longer than that of the inlet tube section. Since aerosol is further atomized while flying, it is preferable that the outlet tube section is longer than the inlet tube section.

In an embodiment of the present invention, the inlet tube section includes a first tapered portion tapered toward the center tube section, the outlet tube section includes a second tapered portion tapered toward the center tube section, and an angle made by the first tapered portion and the center axis of the venturi tube may be larger than an angle made by the second tapered portion and the center axis of the venturi tube. Since the first tapered portion is connected with the opening through which air is introduced, a wide channel for inflow of air is secured, and the angle made by the first tapered portion and the center axis of the venturi tube may be formed to be larger than the angle made by the second tapered portion to satisfy that the outlet tube section is longer than the inlet tube section.

The nicotine inhaler of the present invention can provide an advantage that it is possible to select smoky/smokeless modes and adjust the amount of smoke according to the preference of the user while supplying a predetermined amount of nicotine, and to design the first liquid storage part storing liquid nicotine and the second liquid storage part storing a smoke generating liquid in various structures while securing a channel for air.

Although the present invention was described with reference to preferable embodiments described above, it may be changed or modified in various ways without departing from the gist and scope of the present invention. Therefore, the scope of the appended claims may include such changes and modifications pertaining to the gist of the present invention.
