Description

Liquid substance vaporization device

The present invention relates to a liquid substance vaporization apparatus, and more particularly, to a liquid substance vaporization apparatus that detects a liquid substance in a mixing chamber remaining after flowing back to the inlet path of the liquid substance vaporization apparatus and alarms a user.

A liquid substance vaporizing device is a device that atomizes and inhales health foods or favorite foods such as tobacco liquid, coffee liquid, and oral cleansing liquid instead of eating and drinking, and e-cigarettes are typical.

These liquid substance vaporizers basically include a battery that provides driving power, a storage space that stores the liquid, and an atomizer that atomizes and discharges the stored liquid. In general, outside air is introduced into the vaporizer by the user's suction power. It involves the process of delivering the vaporized liquid substance to the user through the atomizer.

However, the liquid substance flowing out of the storage space for vaporization leaks along the inflow path of the outside air, which is normally formed under the atomizer by its own weight, causing a problem that soils the device or causes discomfort to the user.

Accordingly, various techniques have been proposed to reduce the leakage of liquid substances along the inflow path.However, when used, it is used to stand upright, and due to the nature of the liquid substance vaporizer that is laid down when stored or carried, it is essential to fundamentally block the leakage of liquid substances. It seems that technical difficulties will follow.

Therefore, in order to further alleviate the problem caused by the leakage of the liquid substance, it is necessary to make the user recognize the leakage of the liquid substance in advance.

1 and 2 illustrate internal and external configurations of a liquid substance LS vaporization apparatus VD according to an embodiment of the present invention.

1 and 2, a liquid material (LS) vaporization apparatus (VD) according to an embodiment of the present invention largely includes a cartridge 100 and a battery container 200.

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 health foods or favorite foods that have been eaten and drink in the past.

The battery container 200 is disposed in the mixing chamber 140 in which the liquid material LS is mixed with the outside air by being detached from the cartridge 100 with the battery 220 embedded therein to vaporize the liquid material 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 is 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 face each other decreases (vacuum) as the outside air flows into the cartridge 100 by passing it, 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 to vaporize the liquid material (LS). At this time, 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. Although not done, the USB charging terminal is formed under the battery receiver 200 so that the battery 220 can be easily charged.

Below, a detailed configuration of the interior of the cartridge 100 will be described in detail with reference to FIGS. 3 to 9, but the cartridge 100 including an inflow path IR and a mixing space in FIGS. 5 and 6 for convenience of description The configuration of the lower part and the configuration of the upper part of the cartridge 100 including the discharge path OR and the suction path BR in FIGS. 7 to 9 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 the suction force of the user, and closing the lower portion of the housing 110, and 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 the air, and a liquid material in the mixing chamber 140 ( LS) includes a heater 150 for heating.

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 take into account the flow of fluid, such as storing a liquid substance (LS) inside 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. 7 to 9 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, the closing cap 132 , Including an inlet 133 and a residence space 134. The inlet pipe 131 is a cylindrical tube extending from the bottom 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 due to 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. ) Leakage can be greatly reduced.

In addition, due to the connection of the first inflow path 1IR and the second inflow path 2IR, a chamber structure is formed at the portion where the path is refracted, so that one side of the first inflow path 1IR and the beginning or end of the first inflow path 1IR A residence space 134 is connected and the other side is connected to the start or end of the second inflow path 2IR. This residence space 134 is larger than the diameter of the inflow paths (1IR, 2IR, 3IR) so that the liquid substance flowing back cannot easily enter the first inflow path (1IR), and its shape is in a chamber structure so that it does not take the shape of a flow path. As formed, the liquid substance that has flowed back is retained or stored, and then flows back into the second inflow path 2IR by the user's suction force. At this time, the first inflow path 1IR is formed in a structure spaced apart from the sidewall of the residence space 134 of the chamber structure by a certain distance, and the second inflow path 2IR is formed close to the sidewall. It seems to be advantageous for inflow.

Mixing chamber 140 is a heater 150 is accommodated therein to provide a space for mixing the vaporized liquid material (LS) and the introduced air, and connects the inlet path (IR) and the discharge path (OR), and 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 above-described housing 110 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 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.

Looking at the configuration of the leak alarm 160 further installed in the inflow path IR under the cartridge 100 with reference to FIGS. 5 and 6, the leak alarm 160 according to an embodiment of the present invention is A leak detection sensor 161 is included to detect the liquid material leaking through the inflow path IR and to alarm the user so that the user can recognize the leakage of the liquid material in advance.

The leak detection sensor 161 detects the leakage of the liquid material by allowing the two electrodes 161a and 161b to be energized by remaining in the leaked liquid material. Includes. The first electrode 161a and the second electrode 161b have both electrodes 161a and 161b at one end connected to the battery and the other end respectively installed in the first inflow path IR or the staying space 134 so that the staying space ( 134) It is exposed inside.

Here, when the two electrodes 161a and 161b are installed inside the first inflow path 1IR, the first electrode 161a is a first inflow path ( 1IR) is formed extending along the circumferential direction, and the second electrode 161b is a first inlet passage at the rear of the direction of the air in the first inlet passage 1IR, which is a position spaced apart from the first electrode 161a by a predetermined distance. It is formed extending along the circumferential direction of (1IR). Accordingly, the leaked liquid substance flows backward to the first inflow path 1IR and remains in the first inflow path 1IR, so that when the first electrode 161a and the second electrode 161b are energized, the leak detection sensor 161 ) Detects whether a liquid substance leaks in the inflow path (IR). At this time, the positions of the first electrode 161a and the second electrode 161b may be changed to each other, and the leaked liquid material remaining in the first inflow path 1IR by being installed at a position adjacent to the staying space 134 is removed from the cartridge ( 100) It is desirable to allow the user to recognize it before it leaks completely to the outside. In addition, it is preferable that the distance between the two electrodes 161a and 161b be separated by a set distance so as not to be too wide or too narrow, so that the user can recognize in advance whether the leakage is largely increased even if it does not react to a too small leakage amount. .

On the other hand, when the two electrodes 161a and 161b are installed inside the staying space 134, the first electrode 161a is the upper surface 134b of the staying space 134 adjacent to the inner side 134c of the staying space 134 ) Extending along the edge, and the second electrode 161b extending along the edge of the lower surface 134a of the staying space 134 adjacent to the first inflow path 1IR. This means that when the liquid substance leaked into the residence space 134 is almost full, the first electrode 161a and the second electrode 161b are energized, or when the liquid substance vaporizer is laid, the leakage into the residence space 134 When more than 1/3 of the liquid substance is filled, the first electrode 161a and the second electrode 161b are energized, so that the leakage substance is detected after actively utilizing the residence space 134 formed in a chamber structure for residence. . Again, it goes without saying that the positions of the first electrode 161a and the second electrode 161b may be changed from each other.

Through the above process, when residual liquid material leaked from the first inflow path 1IR or the staying space 134 is detected in the leak detection sensor 161, the operation lamp installed outside the battery receptor 200 described above (240) may indicate a set color, or may flash at a certain period to indicate whether or not leakage is independent of whether it is operated or not.

Referring to Figures 3, 4, 7 to 9, looking at the configuration for forming the discharge path (OR) and the suction path (BR) on the top of the cartridge 100, the liquid mixing pipe 141 of the mixing chamber 140 is a housing The discharge path OR of the vaporized liquid material LS extended to the top of 110 is provided to extend to the top of the housing 110, and the mouthpiece 120 is fitted on the top of the housing 110 Thus, a refracted suction path BR connected to the discharge path OR on the upper portion of the housing 110 is provided. Here, a configuration of a residue evaporator 170 is further installed on 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), and a path tip 123 and a refraction 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 on a virtual axis different from the discharge path OR. The vaporized liquid substance LS formed and discharged is gravity settled by the 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 portion of the housing 110, and the path tip 123 is fitted to the top of the housing 110 to close the top 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 secretion product of a user, 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 problems, it is preferable that the residue evaporator 170 is installed in the refraction space 124, and for this purpose, a configuration of a residue detection sensor 171 and an evaporation conductive pattern 172 is included. .

The residue detection sensor 171 includes a first electrode 171a and a second electrode 171b having one end connected to the battery 220 and the other end exposed to the refraction space 124, respectively, across the housing 110 do. At least one first electrode 171a is installed on the inner surface 124c of the refraction space 124 and is exposed in a state extending in the circumferential direction along the inner surface 124c, and the second electrode 171b is discharged. At least one is installed on the lower surface 124a of the refractive space 124 adjacent to the path OR, and 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 171a and the second electrode 171b, 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 171a is formed of the inner surface 124c of the refraction space 124 and may be installed to contact the lower surface 124a, but the residue evaporator 170 is used to prevent excessive use of the battery 220. ), the first electrode 171a may be spaced apart from the lower surface 124a of the refraction space 124 by a certain height or more so that it is operated only when the residues accumulate above a certain water level.

The evaporation conductive pattern 172 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 171, 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 171, 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 172 may be formed integrally as one, but may be divided into several patterns along the lower surface 124a of the refracting space 124 to form a plurality, and the residue in the refracting space 124 When sensed at a specific position on the lower surface 124a, only the evaporation conductive pattern 172 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 171 and the evaporation conductive pattern 172 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 171 at the bottom, the evaporation conductive patterns 172 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 171 and the evaporation conductive pattern 172 in the residue evaporator 170 are unified into one, so that the sensing function and the heating function can be performed together. Specifically, the first electrode 171a of the positive electrode and the second electrode 171b 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 171b of the negative electrode is adjacent to each other to be refracted. When the residue of the space 124 passes through the adjacent first electrode 171a and the second electrode 171b, the electrode itself heats up to evaporate the residue. At this time, the first electrode 171a and the second electrode 171b are preferably formed at close intervals, and as described above, the inner surface 124c of the refractive space 124 and the discharge hole 123a are connected. However, since the residue is usually generated in the blind spot or remains for a long time, the first electrode 171a and the second electrode 171b 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 protection scope of the present invention should be determined by the technical spirit of the appended claims.
