Description

Liquid substance vaporization device

The present invention relates to a liquid substance vaporization device, and more particularly, after the operation of the liquid substance vaporization device operating using a person's suction power, the residue of the liquid substance remaining in the mouthpiece of the liquid substance vaporization device or the user's secretion It relates to a liquid substance vaporization device capable of removing.

A liquid substance vaporizer is a device that atomizes and inhales health foods or favorite foods such as tobacco liquid, coffee liquid, and mouthwash liquid instead of drinking and drinking, and an electronic cigarette is a typical example.

Such a liquid substance vaporization apparatus generally includes a battery providing driving power, a storage space for storing the liquid phase, and an atomizer for atomizing and discharging the stored liquid phase. At this time, in the process of discharging the atomized liquid, the liquid material vaporized by the atomizer is mixed with the inflowed outdoor air by introducing outside air with the user's suction force, so that the vaporized liquid material rides on the flow of the outside air and faces the user's mouth. It consists of a process.

However, when the vaporized liquid substance is transported in the form of an aerosol, the vaporized liquid substance in the form of relatively large particles is transferred to the discharge path or inhalation path of the vaporized liquid substance while the vaporized liquid substance faces the user's mouth. By inertial collision and re-settling by gravity, it is not easily transmitted to the user, as well as including one or more refracted paths or a specific space for refraction of the path so that external foreign substances do not easily enter the discharge path or the suction path. It is common.

However, it may cause hygiene problems according to the remaining of the liquid substance vaporized or the secretion of the user in such a refracted path or a specific space therefor.

The cartridge 100 stores the liquid substance LS, vaporizes it through the built-in heater 150, and provides it to the user, thereby allowing the user to inhale the health food or favorite food that has been eaten in the past.

The battery container 200 is disposed in the mixing chamber 140 in which the external air and the vaporized liquid substance LS are mixed by being detached from the cartridge 100 with the battery 220 embedded therein to vaporize the liquid substance LS. In addition to supplying power to the heater 150 to be used, it serves as a handle for the user to hold the liquid material (LS) vaporizer (VD). Here, the electrode of the heater 150 is exposed through the lower portion of the cartridge 100 and is electrically connected to the electrode of the battery 220 exposed in the coupling cover 210.

Meanwhile, the cartridge 100 operates by being inserted into the battery receptor 200, and the liquid substance LS can be vaporized through the following process so that the user can inhale.

When the cartridge 100 is seated and coupled to the battery receptor 200, the vacuum sensor 230 waits in the sleeping mode, and the user suction force into the cartridge 100 through the suction port 121 of the mouthpiece 120. When the pressure in the space where the cartridge 100 and the battery container 200 faces is lowered (vacuum) as the outside air flows into the cartridge 100 by passing through, the vacuum sensor 230 detects the pressure drop The liquid material (LS) vaporizer (VD), which was in the sleeping mode, is switched to the operation mode, and power is supplied to the heater 150 to generate heat, thereby vaporizing the liquid material (LS). In this case, the vacuum sensor 230 may adjust the amount of heat generated in proportion to the heat generation operation of the heater 150 and the size of the suction power by calculating the size of the user's suction operation and suction power according to the pressure drop.

In addition, the operation process of the liquid substance (LS) vaporization device (VD) of the present invention can be made to be recognized by the user through the operation lamp 240 installed on the outer circumferential surface of the battery receptor 200 and exposed. It goes without saying that the USB charging terminal is formed under the battery receiver 200 so that the battery 220 can be easily charged.

Below, the detailed configuration of the cartridge 100 and the interior of the cartridge 100 is described with reference to FIGS. 3 to 7, and the configuration of the lower portion of the cartridge 100 including an inflow path IR and a mixing space for convenience of description And the configuration of the upper portion of the cartridge 100 including the discharge path (OR) and the suction path (BR) will be described separately.

Referring to Figure 3, the cartridge 100 is a housing 110 that forms the entire outer shape of the cartridge 100, a mouthpiece 120 receiving a suction force of the user, and closing the lower portion of the housing 110 ) A base 130 providing an inflow path IR of the outside air inside, a mixing chamber 140 forming a mixing path or space between the vaporized liquid material LS and air, and a liquid material in the mixing chamber 140 ( It includes a heater 150 for heating LS).

Referring to Figures 3 and 4, looking at the configuration for forming the inlet path (IR) and the mixing space under the cartridge 100, the housing 110 constitutes the main body of the cartridge 100, A storage space 111 of the liquid material LS is included therein while forming the overall appearance. The cartridge 100 of the present invention has a configuration that must consider the flow of fluid, such as storing a liquid substance (LS) therein and receiving air from the outside, and has an air inlet path (IR) and an outlet path (OR). It is preferable that the rest of the parts are integrally formed for closure.

The mouthpiece 120 is coupled to the upper portion of the housing 110 to provide the user's suction power to the discharge path OR and the inflow path IR, and a detailed description thereof will be described in detail again in FIGS. 5 and 6 to be described later. I will do it.

The base 130 is fitted to the lower portion of the housing 110 to close the lower portion of the housing 110 as well as provide an inflow path (IR) of the outside air, and the inlet pipe 131 and the closing cap 132 And an inlet 133. The inlet pipe 131 is a cylindrical tube extending from the bottom surface of the base 130 to the top, and forms a straightened first inlet passage 1IR without being refracted among the air inlet passages IR. do. At this time, the inlet pipe 131 is preferably formed to have a predetermined width so that a large amount of air can be introduced, and the closing cap 132 having a certain strength to prevent the inflow of foreign substances and to prevent deformation by heat or physical force. Can be installed to close the opening. However, for the inflow of air, a separate inlet 133, which is an opening of the curved path, is formed in the facing portion of the closing cap 132 and the inlet pipe 131 so that a small amount of air is continuously supplied to the inlet pipe 131 Make it possible.

At this time, the above-described inlet pipe 131 is disposed to be formed higher than the mixing space in the side of the mixing space provided by the mixing chamber 140, so that the inlet pipe 131 is a forward inflow path (IR) of the outside air as described above. When the phosphorus first inflow path 1IR is provided, the second inflow path 2IR in the reverse direction and the third inflow path 3IR in the transverse direction are formed. The inflow path (IR) is extended and refracted by the first inflow path (1IR) and the third inflow path (3IR) including the second inflow path (2IR) in the reverse direction to form a liquid substance (LS) through the inflow path (IR). ) Leakage can be greatly reduced.

The mixing chamber 140 is to provide a space for mixing the vaporized liquid material (LS) and the introduced air by receiving the heater 150 therein, and connects the inlet path (IR) and the discharge path (OR). It includes a mixing pipe 141, a liquid induction hole 142 and a wick 143. The liquid mixing tube 141 is a tube-shaped tube disposed through the center of the housing 110 described above, and forms a discharge path OR connected to the inlet path IR. The liquid induction hole 142 is to communicate the inside of the storage space 111 and the liquid mixing pipe 141 below the liquid mixing pipe 141, and is symmetrical along the circumferential direction of the liquid mixing pipe 141. By being formed in a plurality, the liquid substance (LS) accommodated in the storage space 111 in the flow of air introduced through the inlet path IR and directed to the discharge path OR can be attracted into the liquid mixing pipe 141 Provide the furnace. The wick 143 is to provide a liquid material (LS) attracted from the liquid attraction hole 142 to the heater 150, and is installed along the inner circumferential surface of the liquid mixing pipe 141 by covering the liquid attraction hole 142. The attracted liquid material LS is evenly distributed between the liquid mixing pipe 141 and the heater 150.

The heater 150 is accommodated in the mixing chamber 140 and absorbed by the wick 143 in the mixing chamber 140 through power supplied from the battery 220 to heat and vaporize the liquid substance LS. It includes a heating body 151, a heat transfer body 152, and a communication hole 153. The heating element 151 is a spiral heating coil having one end connected to the battery 220 and the other end being accommodated in the heat transfer element 152 to generate heat, and the heat transfer element 152 is formed in a tube shape to form a mixing chamber 140 ) It is a rigid member made of ceramic material in which the liquid material LS of the wick 143 is vaporized by transferring heat from the heating body 151 to the wick 143 by pressing the wick 143 in a face-to-face state. The communication hole 153 is a through hole formed in the center of the heat transfer body 152 and connects the air inflow path IR and the discharge path OR in the liquid mixing pipe 141.

Referring to Figures 3, 5 to 7, looking at the configuration for forming the discharge path (OR) and the suction path (BR) above the cartridge 100, the liquid mixing pipe 141 of the mixing chamber 140 is a housing 110 ), the discharge path OR of the vaporized liquid substance LS extends to the upper portion of the housing 110, and the mouthpiece 120 is inserted into the upper portion of the housing 110 to provide a housing (110) Provides a refracted suction path BR connected to the upper discharge path OR. Here, a configuration of a residue evaporator 160 is further installed in the mouthpiece 120 to remove the liquid substance LS remaining in the mouthpiece 120 or the user's secretion (hereinafter, referred to as “residue”).

The mouthpiece 120 is coupled to the upper portion of the housing 110 to provide the user's suction power to the discharge path (OR) and the inflow path (IR), as outlined above, and the suction port 121, the suction seal ( 122), a path tip 123 and a refractive space 124.

The suction port 121 is a through hole formed on the upper portion of the mouthpiece 120 so that the user's suction force can be transmitted to the inside of the housing 110 through the mouthpiece 120, and is on a virtual axis different from the discharge path OR. The formed and discharged vaporized liquid substance LS is gravity settled by inertial collision and is collected again as the liquid substance LS, as well as reducing the intrusion of external foreign substances. The suction sealing 122 is for sealing the gap between the path tip 123 and the upper part of the housing 110, and the path tip 123 is fitted to the upper part of the housing 110 to close the upper part of the housing 110 However, the discharge path OR formed by the liquid mixing pipe 141 described above is exposed to the upper portion of the housing 110 through the discharge hole 123a formed in the inner center. The refraction space 124 is a space of a rectangular structure formed between the path tip 123 and the inlet 121, and the air discharged from the discharge path OR through the discharge hole 123a is within the suction path BR. After convection, the discharge path (OR) is connected to the center of the lower surface (124a) to be discharged through the suction port (121) formed at a position different from the extension line of the discharge path (OR), and suction ports (121) on both sides of the upper surface (124b) ) Is a chamber of a rectangular structure that is symmetrically connected.

At this time, in the refractive space 124, there is a problem in that an aerosol of the liquid material LS or a residue, which is a user's secretion, accumulates on the lower surface 124a of the refractive space 124, thereby causing problems for portability and hygiene.

Therefore, in order to solve the above problem, it is preferable that the residue evaporator 160 is installed in the refraction space 124, and for this purpose, a configuration of the residue detection sensor 161 and the evaporation conductive pattern 162 is included. .

The residue detection sensor 161 includes a first electrode 161a and a second electrode 161b having one end connected to the battery 220 and the other end exposed to the refraction space 124 across the housing 110. do. At least one first electrode 161a is installed on the inner surface 124c of the refractive space 124 and is exposed in a state extending in the circumferential direction along the inner surface 124c, and the second electrode 161b is discharged. At least one is installed on the lower surface 124a of the refractive space 124 adjacent to the path OR, but is exposed in a state extending along the circumferential direction of the discharge path OR. Accordingly, when the residue of the refraction space 124 energizes the first electrode 161a and the second electrode 161b, the residue of the refraction space 124 may be detected depending on whether or not the refraction space 124 is energized.

Here, the first electrode 161a is formed on the inner surface 124c of the refraction space 124 and may be installed to contact the lower surface 124a, but the residue evaporator 160 is used to prevent excessive use of the battery 220. ), the first electrode 161a may be spaced apart from the lower surface 124a of the refraction space 124 by a predetermined height or more so that it is operated only when the residue accumulates above a predetermined water level.

The evaporation conductive pattern 162 is installed in a state connected to the battery 220 across the housing 110 in the same manner as the electrodes of the residue detection sensor 161, and the lower surface 124a of the refracting space 124 is Accordingly, when at least one is installed and the residue of the refraction space 124 is detected by the above-described residue detection sensor 161, heat is generated by the power supplied from the battery 220 and the residue of the refraction space 124 Evaporate.

At this time, the evaporation conductive pattern 162 may be formed integrally as one, but may be divided into a plurality of patterns along the lower surface 124a of the refracting space 124 to form a plurality, and the residue in the refracting space 124 When detected at a specific position of the lower surface 124a, only the evaporation conductive pattern 162 in the portion where the residue is sensed heats up, thereby reducing the consumption of the battery 220.

For example, as shown in FIG. 7, the residue detection sensor 161 and the evaporation conductive pattern 162 are formed by being divided into four, respectively, along the circumferential direction of the discharge hole 123a, and the upper left, upper right and right When a residue is detected by the residue detection sensor 161 at the bottom, the evaporation conductive patterns 162 at the upper left, upper right, and lower right also generate heat to remove nearby residues.

Meanwhile, although not shown in the drawing, the functions of the residue detection sensor 161 and the evaporation conductive pattern 162 in the residue evaporator 160 are unified into one, so that the sensing function and the heating function can be performed together. Specifically, the first electrode 161a of the positive electrode and the second electrode 161b of the negative electrode are arranged to connect the inner surface 124c of the refraction space 124 and the discharge hole 123a in a structure in which the second electrode 161b of the negative electrode alternately When the residue of the space 124 passes through the adjacent first electrode 161a and the second electrode 161b, the electrode itself heats up to evaporate the residue. At this time, the first electrode 161a and the second electrode 161b are preferably formed at close intervals, and as described above, connect the inner surface 124c of the refractive space 124 and the discharge hole 123a However, since the residue is usually generated in the blind spot or remains for a long time, the first electrode 161a and the second electrode 161b along the lower surface 124a of the inner surface 124c of the refractive space 124 These can be arranged alternately.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical scope of the present invention should be determined by the technical spirit of the appended claims.
