Description

Electronic cigarette that can be used with various liquid supply media by temperature control

The present invention relates to an electronic cigarette, and more particularly, it is possible to use a liquid supply medium of various materials by controlling the temperature of the heat generating unit, it is possible to secure a sufficient storage space of a small size and the use of various atomizer structures Possible electronic cigarette.

An electronic cigarette is an electronic device that inhales atomized vapor by atomizing nicotine by heating the liquid phase with heat.

Such electronic cigarettes generally include an electronic cigarette body, as in FIG. 1; battery; It consists of an atomizer and a cartridge, where the cartridge is a portion for storing the electronic cigarette liquid, and the atomizer is a portion connected to the cartridge and heated to atomize the liquid phase of the cartridge.

In general, the heat generating portion of the atomizer uses a nichrome wire that is a heat transfer coil to generate heat well, and uses a glass fiber such as a yarn made of glass fiber as a supply for directly supplying a liquid phase to the heat generating portion.

On the other hand, the cartridge stores the liquid phase, the liquid storage method may be stored in a tank method, stored in a member such as cotton or a storage container method for storing ink in the pen.

In the case of e-cigarettes storing the liquid phase, the liquid storage tank is enlarged to increase the use time of the liquid stored in the liquid storage tank. As a result, the size of the e-cigarette is gradually increased, and thus the e-cigarette is enlarged. There existed a problem that the ease of use by this was reduced.

On the other hand, in the case of the conventional electronic cigarette, glass fiber is used as a liquid supply medium, such glass fiber is easily broken and its durability is very weak, and also the problem that the broken debris may be absorbed into the human body. In addition, when the glass fiber is in direct contact with the heating wire to vaporize the liquid phase, instantaneous combustion occurs when the liquid phase is in contact with the overheated heating wire. In addition, toxic substances may occur.

In particular, when the liquid is combusted due to the high heat of the heating wire, glycerin, the main raw material of the e-cigarette liquid, generates acrolein and acetone. Among them, acrolein is the most powerful carcinogen that causes lung cancer. .

In the case of glass fiber, the WHO's International Cancer Research Institute (IARC) has recently been classified as a human carcinogenic substance '2B', which poses a big problem that it is a controversial hazard.

In addition, in the case of the conventional electronic cigarette, since the atomizer structure composed of a single form is mounted, there is a limit to the taste expression of the electronic cigarette by atomizing the liquid phase with only one atomizer regardless of the type of liquid phase.

Therefore, in order to solve the problems of the prior art electronic cigarette, the present inventors, after research, can use materials such as natural fibers and synthetic fibers as a liquid supply medium (wick), diversification of liquid supply medium material In order to prevent the combustion of the liquid supply medium to limit the excessive temperature rise and temperature control of the heat generating portion, while ensuring sufficient liquid storage space can be miniaturized the electronic cigarette device, the use of various atomizer structure The development of electronic cigarettes has made it possible.

A second electrode tube supplied with power having a polarity opposite to that of the electrode tube; A wick installed in the interior space of the second electrode tube and having a liquid phase stored in the interior space of the second electrode tube and supplying the liquid phase; And a heat generation unit configured to generate heat through power supplied through the first electrode tube and the second electrode tube to atomize the liquid phase supplied from the wick, and the heat generation unit may be provided at one end of the first electrode tube not connected to the main body. The second electrode tube is in electrical contact with the second electrode tube and is in electrical contact with each other. The bimetal includes two metal plates having different coefficients of thermal expansion, and the bimetal has one side in contact with the heat generating unit and the other side in the second side. The bending temperature of the metal plate having a high thermal expansion coefficient among the two metal plates of the bimetal, which is in contact with the electrode tube and is connected to the second electrode tube, is a critical temperature value at which the heat generating portion generates heat, and the temperature of the heat generating portion is When the critical temperature value is reached, a metal plate having a high coefficient of thermal expansion among the two metal plates expands to the second electrode tube. One side of the connected bimetal is spaced apart from the second electrode tube, and the power supplied to the heating unit is cut off, and provides an electronic cigarette.

The first housing encloses an area in which the liquid phase is stored, and an inner space of the first housing is enclosed from the main body and the second housing, and the second electrode tube defines an area in which the liquid phase is stored. One or more openings extending along the length direction of the opening of the second electrode tube, through which the area in which the liquid phase of the second electrode tube is stored and the internal space of the first housing become fluidly communicable; The liquid phase is thereby filled in the region in which the liquid phase of the second electrode tube is stored and the internal space of the first housing.

The wick is in the form of a net, and the wick may be made of any one of natural fibers or synthetic fibers.

The heat generating unit may be configured in various forms, and typically, may be made of a flexible non-combustible metal mesh. In this case, the flexible non-flammable metal mesh is rolled up in a roll shape and is accommodated in the second electrode tube with the first electrode tube inserted into the roll shape, and the flexible non-flammable metal mesh is roll-shaped.

The wick thereby supplies the liquid phase to the flexible non-flammable metal net and prevents shorting of the heat transfer portion.

As another example, the flexible non-flammable metal mesh may include an insulating part positioned on the insulating part so as to be parallel to the heat transfer part in a state in which the flexible non-combustible metal network is unfolded; And an air passage extending along the length direction of the roll shape, wherein the insulation portion overlaps the surface of the heat transfer portion before the flexible non-flammable metal mesh is rolled into the roll shape, and in this state, the flexible non-combustible metal When the net is rolled up into the scroll shape, it is located between the first electrode and the second electrode to prevent short.

When a flexible non-combustible metal mesh of this type is used, the wick is installed in the second electrode tube so as to wrap around the flexible non-combustible metal mesh in a roll shape.

As another form of the heat generating portion, a heating wire may be used. In this case, further comprising a fixing net of insulating material surrounding the outer surface of the first electrode tube, wherein the wick is rolled around the fixing net to surround the fixing net, the wick is the length of the scroll shape A portion in the axial direction parallel to the direction is inserted into the region in which the liquid phase is stored. And the heating wire is wound around the roll-shaped wick on the opposite side of the inserted portion of the wick.

To this end, the atomizer structure is designed such that the temperature rise of the heat generating unit 240 is limited, whereby it is possible to prevent the combustion of the wick 230 when using natural fibers or synthetic fibers as the wick 230, The choice of wick material has expanded.

Hereinafter, the atomizer structure will be described in detail.

* Description of the atomizer structure that limits the rise in temperature of the heating element

Referring to FIG. 1, the atomizer structure may include a first electrode tube 210; Second electrode tube 220; Wick 230; And a heat generating unit 240.

The first electrode tube 210 is formed in the form of a hollow tube, the lower end of the tube is electrically connected to the main body 300, negative (-) power or positive (+) from the main body 300 and the battery 400 Power is turned on. For example, negative power is input to the first electrode tube 210. As shown in FIG. 2, the first electrode tube 210 has a lower end connected to the main body 300 and an upper end of the tube adjacent to the suction part 100. For example, the first electrode tube 210 may be made of a metal material for power connection with the main body 300, and in another example, the first electrode tube 210 may be a synthetic resin material, and in this case, a portion connected to the main body 300. Metal terminals may be installed.

FIG. 3 is a diagram for describing the second electrode tube illustrated in FIG. 2.

Referring to FIG. 3, the second electrode tube 220 is formed in the form of a hollow tube, and the lower end of the tube is electrically connected to the main body 300 and has a different polarity from the power input to the first electrode tube 210. Power is input. For example, when negative power is input to the first electrode tube 210, positive (+) power is input to the second electrode tube 220. The second electrode tube 220 may be divided into a plurality of regions. For example, the power connection region 220a connected to the main body 300, the heat generating portion accommodating region 220c positioned opposite to the power connection region 220a in the length direction of the second electrode tube 220, and The liquid storage region 220b may be disposed between the power connection region 220a and the heating unit accommodating region 220c. The liquid storage region 220b is sealed from the power connection region 220a and the heat generating portion accommodating region 220c, whereby the liquid phase is stored in the liquid storage region 220b. There is no particular limitation on the form of sealing the liquid storage region 220b.

In addition, the second electrode tube 220 accommodates the first electrode tube 210 and the liquid phase, and has a diameter or cross-sectional area sufficient to accommodate the first electrode tube 210 and the liquid phase. That is, the diameter or cross-sectional area of the second electrode tube 220 is larger than the diameter or cross-sectional area of the first electrode tube 210. For example, the diameter or cross-sectional area of the liquid storage region 220b is greater than the diameter or cross-sectional area of the first electrode tube 210, and the diameter or cross-sectional area of the power connection region 220a and the heat generating portion accommodating region 220c. May be larger than the diameter or cross-sectional area of the liquid storage region 220b. Due to the shape of the second electrode tube 220, as shown in FIG. 2, the first electrode tube 210 is inserted in the axial direction of the second electrode tube 220 to be accommodated in the second electrode tube 220. It is. At this time, the inner surface of the liquid storage region 220b is spaced apart from the outer surface of the first electrode tube 210, and the liquid phase is stored in the space. A form in which the liquid phase may be filled into the liquid storage region 220b will be described below.

The first electrode tube 210 and the second electrode tube 220 are components for supplying power to the heat generating unit 240, the heat generating unit 240 and the wick 230 described below to atomize the liquid Parts for

First, the heat generating unit 240 is electrically connected to the first electrode tube 210 and the second electrode tube 220 is supplied with power, thereby generating heat to atomize the liquid phase supplied from the wick 230. The heat generating part 240 is installed in the heat generating part accommodating area 220c of the second electrode tube 220. As described above, the heat generating part 240 may use a flexible non-flammable metal net, and a description of the heating part using the flexible non-flammable metal net will be described in detail below.

The heating unit 240 is installed in the heating unit accommodating region 220c of the second electrode tube 220 in a form surrounding the first electrode tube 210, and at this time, a power connection of one side of the heating unit 240 is performed. The part is connected to the first electrode tube 210, and the power connection part of the other side is connected to the second electrode tube 220. One side of the heat generating part 240 connected to the second electrode tube 220 is connected to the second electrode tube 220 through the bimetal 250.

The bimetal 250 is to prevent the second electrode tube 220 and the heating unit 240 from being connected or connected according to the temperature change of the heating unit 240. The first metal plate 251 and the second thermal expansion coefficient having different coefficients of thermal expansion are formed. 2 metal plate 252 is included. For example, the first metal plate 251 may be a metal plate having a high thermal expansion coefficient, and the second metal plate 252 may be a metal plate having a lower coefficient of thermal expansion than the first metal plate 251. Therefore, when the bending generation temperature (temperature at which the metal plate starts to expand) is applied to the first metal plate 251 having a high coefficient of thermal expansion, the first metal plate 251 is warped toward the second metal plate 252 having a relatively low coefficient of thermal expansion. Is generated.

In this bimetal 250, in order for the heating part 240 to be electrically connected to the second electrode tube 220, for example, one surface of the second metal plate 252 is not connected to the first electrode tube 210. The second metal plate 252 is bent toward the second electrode tube 220 on the opposite surface of the one surface that is fixed to the power connection part of one side of the heat generating part 240 and is in contact with the heat generating part 240. May be in contact with the tube 220. In addition, the first metal plate 251 may be located at a portion of the second metal plate 252 that is not in contact with the second electrode tube 220 on an opposite surface of the one surface that is in contact with the heat generating unit 240.

In this form, when the temperature of the heat generating part 240 rises and the elevated temperature of the heat generating part 240 reaches the bending generation temperature of the first metal plate 251, the first metal plate 251 expands to form the second metal plate. Warping toward 252 occurs. As a result, the second metal plate 252 in which the warpage is generated is pushed in a direction away from the second electrode tube 220 by the first metal plate 251, and at this time, the second metal plate in contact with the second electrode tube 220. One surface of 252 is spaced apart from the second electrode tube 220. Therefore, when the temperature of the heat generating unit 240 reaches the bending generation temperature corresponding to the thermal expansion coefficient of the first metal plate 251, the power delivered to the heat generating unit 240 is cut off, the temperature of the heat generating unit 240 No longer rises. When the temperature of the heat generator 240 gradually drops, the expanded first metal plate 251 is restored to its original state, and the second metal plate 252 is in contact with the second electrode tube 220 again.

As can be seen from this process, the temperature rise of the heat generating unit 240 is limited by the expansion and restoration of the bimetal 250 according to the temperature change of the heat generating unit 240. Therefore, the critical temperature value at which the heat generation temperature of the heat generating unit 240 is limited is set to the bending generation temperature of the metal plate having the high thermal expansion coefficient among the bimetals 250.

The wick 230 is installed around the heat generating unit 240 to contact the heat generating unit 240 to supply the liquid phase to the heat generating unit 240. To this end, the wick 230 has a cylindrical shape rolled up in a roll shape, for example, is installed around the heat generating part 240 and accommodated in the second electrode tube 220, and an axis parallel to the longitudinal direction of the cylindrical shape. One side of the direction is inserted into the liquid storage region 220b of the second electrode tube 220. As a result, the liquid phase stored in the liquid storage region 220b is continuously supplied to the heat generating unit 240.

On the other hand, the atomizer structure is not limited to the internal space of the second electrode tube space for storing the liquid phase, and is designed to ensure a sufficient space for storing the liquid phase, thereby miniaturizing the electronic cigarette structure In addition, the storage capacity of the liquid phase was not lowered.

Hereinafter, the structure of the liquid storage space will be described.

* Description of the structure of the liquid storage space

As mentioned above, the atomizer structure is housed within the first housing 510 and the second housing 520.

The first housing 510 is coupled to the main body 300, and the second housing 520 is coupled to the first housing 510. In this case, the first housing 510 is sealed from the main body 300 and the second housing 520. In this state, the liquid storage region 220b of the second electrode tube 220 is positioned inside the first housing 510, and the first housing 510 surrounds the liquid storage region 220b. That is, the inner surface of the first housing 510 is spaced apart from the outer surface of the liquid storage region 220b of the second electrode tube 220. As a result, a space for storing the liquid phase is provided between the first housing 510 and the second electrode tube 220.

Meanwhile, one or more openings 221 are provided in the liquid storage region 220b of the second electrode tube 220. The opening 221 extends along the longitudinal direction of the second electrode tube 220. The opening 221 allows the liquid storage region 220b and the interior of the first housing 510 to be in fluid communication with each other, whereby the liquid phase is formed in the liquid storage region 220b and the second electrode tube 220. 1 may be stored in all of the internal space of the housing 510.

By this structure, the liquid phase stored in the liquid storage region 220b of the second electrode tube 220 is not limited to being stored only in the liquid storage region 220b of the second electrode tube 220, and further 1 The space for storing the liquid phase is enlarged to the inside of the housing 510.

Accordingly, the first housing 510 may be used as a liquid storage container capable of storing a liquid phase, and the liquid phase injected into the first housing 510 may be a liquid storage region of the second electrode tube 220 through the opening 221. May be filled in 220b.

With this structure, even if the second electrode tube 220 is inserted in the first housing 510 in the axial direction, the space capable of storing the liquid phase inside the first housing 510 due to the second electrode tube 220. It is possible to ensure a sufficient space for storing the liquid phase inside the first housing 510 without loss of.

In addition, since the first housing 510 and the second housing 520 can be easily coupled and fastened, it is easy to replace the atomizer structure accommodated in the first housing 510 and the second housing 520.

On the other hand, the electronic cigarette structure of the present invention can set the manual temperature according to the recipe and atomization and taste expression of the liquid, can display the set temperature, etc., and detects the temperature of the heat generating unit according to the detected temperature change It is designed to maintain the manual temperature set by the user by controlling the power delivered to the heating unit. Hereinafter, the main body capable of temperature setting and temperature control will be described.

* Description of the body temperature control and temperature control

The main body 300 receives power from the battery 400 and supplies power to the atomizer structure. To this end, the main body 300 includes a first electrode part 310, a second electrode part 320, and a printed circuit board 330.
