Description

The present disclosure relates to a liquid e-cigarette device.

Conventionally, a liquid type electronic cigarette device that generates an aerosol by heating a liquid aerosol source has been proposed (see, for example, Patent Document 1).

FIG. 5 is a side sectional view of the atomization unit in the conventional liquid type electronic cigarette device.

In the figure, reference numeral 810 is an atomization unit, and a connector portion 812 formed at one end thereof is connected to an electrical component unit (not shown) in a liquid electronic cigarette device. Further, the other end of the atomization unit 810 is a mouthpiece unit 811 in which a suction port 811a is formed. The user holds the mouthpiece unit 811 by mouth and sucks the aerosol from the suction port 811a. A filter 811b is arranged in the atomization unit 810 at a position adjacent to the mouthpiece unit 811.

The connector portion 812 includes an air introduction hole 817 for introducing outside air into the inside, and an air flow path 815 communicating with the electrical component unit. Further, a tubular aerosol source holder 813 made of a porous body is arranged at a position adjacent to the connector portion 812 in the atomization unit 810. The aerosol source for generating an aerosol is a liquid such as glycerin or propylene glycol, and the aerosol source holder 813 made of a porous body is impregnated. At the center of the aerosol source holder 813, a tubular body 815a communicating with the air flow path 815 is arranged, and an absorber 816 is arranged so as to cross the tubular body 815a. The absorber 816 is made of glass fiber or the like, and sucks the aerosol source from the aerosol source holder 813. Then, the aerosol source sucked up from the aerosol source holder 813 is heated by a heat source 816a composed of a heating wire wound around the absorber 816 and atomized to become an aerosol.

Further, a tobacco source 814 covered with a film is arranged at a position adjacent to the filter 811b in the atomization unit 810. Then, the hollow needle 815b connected to the mouthpiece unit 811 side end of the tubular body 815a pierces the film covering the tobacco source 814 and destroys a part of the film.

As a result, when the user sucks the suction unit 811 in the mouth, the air introduced from the air introduction hole 817 passes through the cylinder 815a through the air flow path 815 and is mixed with the aerosol in the cylinder 815a. Further, the flavor is added as it passes through the hollow needle 815b and through the aerosol source 814, and is then supplied to the user through the filter 811b and the suction port 811a.

The electrical component unit was detected by including an IC for controlling the operation of the heat source 816a and a control board on which a pressure sensor for detecting a user's suction force is mounted via the air flow path 815. Generate an appropriate amount of aerosol depending on the suction force of the user.

However, in the conventional liquid type electronic cigarette device, since the aerosol source holder 813 and the inside of the electrical component unit communicate with each other via the air flow path 815, the liquid aerosol source is the aerosol source holder 813. It may leak from the vape and flow into the electrical component unit, damaging the control board on which the IC and pressure sensor are mounted.

Here, the problem of the conventional liquid type electronic cigarette device can be solved, and even if the liquid aerosol source leaks, it can be surely prevented from flowing into the electrical component unit, and the size is small.

The electrical component unit includes a third air flow path whose one end is open in the electrical component unit, and when the atomization unit and the electrical component unit are connected, the second air flow path and the third air are connected. It is connected to the flow path.

In other liquid electronic cigarette devices, the atomization unit is further arranged at the upper end and a first connection portion which is a first connection portion arranged at the lower end and is connected to the electrical component unit. The first air flow path further includes an air intake unit, one end of which is opened at a first suction port formed in the mouthpiece unit, and the other end of which is an air intake formed on one side surface of the atomization unit. The second air flow path opens at the mouth, one end opens at the second suction port formed in the mouthpiece unit, and the other end opens at the upper connection port formed at the first connection portion.

In yet another liquid e-cigarette device, the first air flow path further includes a generator passage channel whose upper end opens at the first suction port and extends in the vertical direction to pass through the generator. A lateral channel extending in the left-right direction along the lower surface of the atomizing unit and having one end communicating with a side surface near the lower end of the generator passing channel, and extending in the vertical direction along one side surface of the atomizing unit. The lower end communicates with the upper surface near the other end of the lateral channel, and the upper end includes a side channel that opens at the air intake port.

In FIGS. 1 and 3, reference numeral 1 denotes a liquid type electronic cigarette device according to the present embodiment, in which an atomizing unit 10 that heats and atomizes a liquid aerosol source to generate an aerosol and an operation of the atomizing unit 10 are operated. It is provided with an electrical component unit 20 to be controlled. The user connects the atomization unit 10 and the electrical component by connecting the upper connector 12 as the first connection portion of the atomization unit 10 and the lower connector 21 as the second connection portion of the electrical component unit 20. The unit 20 and the unit 20 are used in combination with each other.

In the present embodiment, the expressions indicating the directions of upper, lower, left, right, front, rear, etc. used to explain the configuration and operation of each part of the atomization unit 10 and the electrical component unit 20 are used. It is not absolute but relative, and is appropriate when each part of the atomization unit 10 and the electrical component unit 20 is in the posture shown in the figure, but when the posture is changed, the posture is changed. It should be changed and interpreted as it changes.

The atomization unit 10 is a cartridge that houses a liquid aerosol source inside, and is replaced and used when the aerosol source is exhausted. Further, the atomization unit 10 has a wick 16 as a generator inside which the aerosol source is heated and atomized to generate an aerosol. The wick 16 is made of, for example, glass fiber or cotton, and a heating wire is wired inside. A power line (not shown) is connected to the heating wire, and power from a battery (not shown) included in the electrical component unit 20 is supplied via the power line. As a result, the wick 16 is heated, the aerosol source of the liquid impregnated in the wick 16 is atomized, and an aerosol is generated.

Further, in the atomization unit 10, a first air flow path 15 is arranged so as to pass through the wick 16. One end of the first air flow path 15 opens at the first suction port 11a formed in the suction unit 11 at the upper end of the atomization unit 10, and the other end is one side surface of the atomization unit 10 (shown in FIG. 1). In this example, it is opened in an air introduction hole 17 as an air intake port formed on the left side surface).

Specifically, the first air flow path 15 includes a wick passage channel 15a as a generator passage channel extending in the vertical direction, a lateral channel 15b extending in the horizontal direction, and a side channel extending in the vertical direction. Includes 15c and. The wick passage channel 15a passes through the wick 16 and is open at the upper end thereof as the first suction port 11a. The lower end of the wick passing channel 15a is closed. Further, the lateral channel 15b extends outward from the center of the lower surface along the lower surface of the atomization unit 10, and its central end communicates with the side surface near the lower end of the wick passage channel 15a and is distal thereof. The end is located near the one side surface of the atomization unit 10 but is closed. Further, the side channel 15c extends along the one side surface of the atomization unit 10, its lower end communicates with the upper surface near the distal end of the lateral channel 15b, and its upper end serves as an air introduction hole 17. It is open on one side of the atomization unit 10.

That is, the first air flow path 15 has a substantially U-shaped shape when viewed from the front, and one end thereof serves as the first suction port 11a and opens to the suction unit 11 at the upper end of the atomization unit 10. The other end serves as an air introduction hole 17, and is formed so as to open on the one side surface of the atomization unit 10 and pass through the inside of the wick 16 in the middle. Therefore, when the user sucks the mouthpiece unit 11 by mouth, air is introduced from the air introduction hole 17 as shown by arrow A, passes through the wick 16 and mixed with the aerosol, and further, the first suction port. It is supplied to the user through 11a. Further, even if the liquid aerosol source leaks from the wick 16 into the first air flow path 15, it does not flow out in the direction of the electrical component unit 20.

In the present embodiment, the second air flow path 18 is arranged in the atomization unit 10. The second air flow path 18 is an independent flow path formed separately from the first air flow path 15 and separated from the first air flow path 15, and is up and down without passing through the wick 16. Extend in the direction. The upper end thereof serves as a second suction port 11b and opens to the suction port unit 11, and the lower end thereof serves as an upper connection port 12a as a connection port and opens to the lower surface of the upper connector 12. The inside of the second air flow path 18 is shielded from the liquid aerosol source contained in the atomization unit 10, and the liquid aerosol source does not infiltrate.

Further, in the electrical component unit 20, a battery as a power source (not shown) and a control board as a control device (not shown) on which an IC for controlling the heating state of the wick 16 and the like are mounted are arranged. A pressure sensor 22 that detects the suction force of the user is also mounted on the control board. Further, in the electrical component unit 20, a suction force detecting flow path 23 as a third air flow path having an opening at the lower end in the electrical component unit 20 and extending in the vertical direction is provided. The suction force detection flow path 23 is formed so as to reach the control board, and specifically, the upper end thereof serves as a lower connection port 21a as a connection port and opens on the upper surface of the lower connector 21. The lower end reaches the pressure detection surface of the pressure sensor 22 and opens. The lower connection port 21a is formed at a position corresponding to the upper connection port 12a of the atomization unit 10, and when the upper connector 12 and the lower connector 21 are connected, the upper connection port 12a and the lower connection are connected. The ports 21a are also connected to each other, whereby the second air flow path 18 and the suction force detection flow path 23 are also connected to each other and communicate with each other. Therefore, when the user holds the suction port unit 11 in the mouth and sucks the air, the air in the second air flow path 18 and the suction force detection flow path 23 is sucked out from the second suction port 11b as shown by the arrow B. Therefore, the suction force of the user is detected by the pressure sensor 22. Since the inside of the second air flow path 18 is shielded from the aerosol source of the liquid contained in the atomization unit 10, the aerosol source of the liquid is the second air flow path 18 and the suction force detection flow path 23. It does not flow into the electrical component unit 20 through the electrical component unit 20.

On the other hand, in the liquid type electronic cigarette device 101 of the comparative example as shown in FIGS. 2 and 4, only the first air flow path 115 is arranged in the atomization unit 110. The first air flow path 115 extends in the vertical direction so as to pass through the wick 116 in the middle thereof, and the upper end thereof serves as the first suction port 111a and opens into the suction unit 111 at the upper end of the atomization unit 110. Then, the lower end serves as the upper connection port 112a and opens to the lower end of the upper connector 112 of the atomization unit 110. Then, when the upper connector 112 and the lower connector 121 are connected in order to connect the atomization unit 110 and the electrical component unit 120, the lower side of the suction force detection flow path 123 arranged in the electrical component unit 120 is connected. The side connection port 121a is connected to the upper connection port 112a of the first air flow path 115, whereby the first air flow path 115 and the suction force detection flow path 123 are also connected to each other and communicate with each other.

In the liquid electronic cigarette device 101 of the comparative example, an air introduction hole (not shown) is formed between the atomization unit 110 and the electrical component unit 120 and / or in the electrical component unit 120, and is shown in FIG. As indicated by arrows D1 and / or D2, external air can flow into the first air flow path 115 through the air introduction hole.

Therefore, in the liquid electronic cigarette device 101 of the comparative example, when the user sucks the mouthpiece unit 111 in the mouth, air is introduced from the air introduction hole as shown by arrows D1 and / or D2, and subsequently. , As indicated by the arrow C, are mixed with the aerosol through the wick 116 and further fed to the user through the first suction port 111a. Further, since the air in the first air flow path 115 and the suction force detection flow path 123 is sucked out from the first suction port 111a as indicated by the arrow C, the suction force of the user is detected by the pressure sensor 122. Will be done.

However, in the liquid electronic tobacco device 101 of the comparative example, since the first air flow path 115 communicates with the lower suction force detection flow path 123, the liquid aerosol source is from the wick 116 to the first air flow path. If it leaks into the 115, it may flow into the electrical component unit 120 through the suction force detection flow path 123 and damage the pressure sensor 122 and a control board (not shown). On the other hand, in the present embodiment, as described above, the liquid aerosol source does not flow into the electrical component unit 20.

As described above, in the present embodiment, the liquid electronic tobacco device 1 includes an atomization unit 10 for accommodating a liquid aerosol source inside and an electrical component unit 20 connected to the atomization unit 10, and is foggy. The conversion unit 10 has a wick 16 that atomizes an aerosol source to generate an aerosol, a first air flow path 15 that passes through the wick 16, and a second air flow path 18 that is separate from the first air flow path 15. Including, the electrical component unit 20 includes a suction force detection flow path 23 having one end opened in the electrical component unit 20, and when the atomization unit 10 and the electrical component unit 20 are connected, the second air flow path 18 and The suction force detection flow path 23 is connected.

As a result, the suction force detection flow path 23 is physically separated from the first air flow path 15 passing through the wick 16, so that even if the liquid aerosol source leaks from the wick 16, it flows into the electrical component unit 20. This can be reliably prevented, and the reliability of the liquid type electronic cigarette device 1 is improved even though it is small in size.

Further, the atomization unit 10 further includes an upper connector 12 arranged at the lower end and connected to the electrical component unit 20, and a mouthpiece unit 11 arranged at the upper end, and the first air flow path 15 has one end. Is opened in the first suction port 11a formed in the suction unit 11, the other end is opened in the air introduction hole 17 formed on one side surface of the atomization unit 10, and one end of the second air flow path 18 is a suction port. It opens at the second suction port 11b formed in the unit 11, and the other end opens at the upper connection port 12a formed in the upper connector 12. Therefore, even if the liquid aerosol source leaks from the wick 16 into the first air flow path 15, it does not flow out in the direction of the electrical component unit 20.

Further, the first air flow path 15 has a wick passage channel 15a whose upper end opens at the first suction port 11a and extends in the vertical direction and passes through the wick 16, and a lateral direction along the lower surface of the atomization unit 10. Lateral channel 15b, one end of which extends vertically along one side surface of the atomization unit 10 and one end of which extends vertically along one side surface of the wick passage channel 15a, and the lower end of which extends near the other end of the lateral channel 15b. Includes a side channel 15c that communicates with and has an upper end that opens in the air inlet hole 17. As described above, since the first air flow path 15 has a substantially U-shaped shape and does not open on the lower surface side of the atomization unit 10, it is assumed that the liquid aerosol source is from the wick 16 to the first air flow path. Even if it leaks into 15, it is possible to surely prevent the liquid from flowing out in the direction of the electrical component unit 20.

Further, the electrical component unit 20 further includes a control board for controlling the wick 16 and a lower connector 21 arranged at the upper end and connected to the atomization unit 10, and the suction force detection flow path 23 has one end. It reaches the pressure sensor 22 on the control board, and the other end opens at the lower connection port 21a formed in the lower connector 21. Therefore, when the user holds the suction unit 11 in the mouth and sucks the air, the air in the second air flow path 18 and the suction force detection flow path 23 is sucked out from the second suction port 11b, so that the user's suction force is pressured. Detected by sensor 22.
