The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, an embodiment of the present invention provides an airway structure 10, which includes an inner shell assembly, a microphone 16, and a vent 18.

The inner shell assembly has a receiving cavity 122, a through hole 124 communicating with the receiving cavity 122, and a gas passage communicating with the through hole 124.

The microphone 16 is disposed in the accommodating cavity 122, the vent 18 is sleeved on the microphone 16, and the vent 18 is used for blocking condensate from entering the microphone 16 and enabling air between the microphone 16 and the air passage to flow.

Through setting up foretell air flue structure, the condensate that produces in the electron cigarette can flow along gas passage usually, probably flows in moreover and holds the chamber 122 in, through locating miaow head 16 with ventilating 18 covers, can obstruct the condensate effectively and enter into miaow head 16 in to avoid the battery pole to scrap, increase of service life reduces use cost.

It should be explained that the microphone is a conventional element in the electronic cigarette, which can be used to detect the number of times of suction by the user, in practical applications, after the condensate enters into the microphone, the condensate will not only damage the microphone, but also damage the battery rod electrically connected with the microphone, and the electronic cigarette will be discarded after the battery rod is damaged, thus increasing the use cost.

Referring to fig. 3 and 4, in some embodiments, the inner housing assembly includes an inner housing 12, the inner housing 12 includes a main body 121 and an accommodating portion 123 fixedly connected to one side of the main body 121, a through hole 124 penetrates through two opposite sides of the main body 121, a first connecting groove 128 communicated with the through hole 124 is formed on one side of the main body 121 away from the accommodating portion 123, the other end of the first connecting groove 128 extends to the top of the main body 121, and the accommodating cavity 122 is an inner cavity of the accommodating portion 123.

Further, the inner housing assembly further includes a sealing member 14, the sealing member 14 is detachably mounted on the inner housing 12, and covers a side of the main body 121 having the first connecting groove 128 to shield the first connecting groove 128, and the first connecting groove 128 forms the gas channel.

In practical applications, the side of the main body 121 facing away from the accommodating portion 123 has a step surface 126, the first connecting grooves 128 are located on the step surface 128, and the sealing member 14 covers the step surface 128.

It will be understood that the groove is a central recess and two convex structures are located on the surface of the object, that is, the first connecting groove 128 is located on the step surface 126 of the main body 121, and when the step surface 126 is covered with a layer of the sealing member 14, the sealing member 14 shields the first connecting groove 128, so that a passage, that is, the gas passage, is formed, and since the sealing member 14 covers the whole step surface 126, and the first connecting groove 128 is communicated with the through hole 124, the corresponding gas passage is also communicated with the through hole 124.

Referring to fig. 6, in some embodiments, the air duct structure further includes a housing 11, the housing 11 is disposed on the main body 121 and is used for pressing the sealing element 14 against the step surface 126, of course, the housing 11 is used for pressing the sealing element 14 on the main body 121 entirely, so that the sealing element 14 is fixed relative to the main body 121.

After the housing 11 is sleeved on the body 121, the top end of the body 121 and the housing 11 may be enclosed to form an atomizing chamber, and an atomizer and other structures are disposed in the atomizing chamber.

It will also be appreciated that the step surface 128 is provided so that the seal 14 does not extend too far beyond the body 121 after the seal 14 overlies the step surface 128, and that if the step surface 128 is not provided, the seal 14 overlies the side of the body 121 facing away from the receiving portion 123, which can interfere with the mounting of the housing 11.

In some embodiments, the inner housing 12 further includes an extension 125 protruding from the top end surface of the main body 121, the extension 125 has a second connecting slot penetrating through two opposite ends thereof and communicating with one end of the first connecting slot 128 away from the through hole 124; when the sealing member 14 is installed on the main body 121, the sealing member 14 covers one side of the extending portion 125 to shield the second connecting groove, thereby forming a gas channel having a gas outlet.

It can be appreciated that the extension 125 actually extends into the atomizing chamber, and after condensate is generated in the atomizing chamber, the condensate may be accumulated at the bottom of the atomizing chamber, i.e. the top end of the main body 121, and the extension 125 protrudes from the end surface of the top end of the main body 121, and the air outlet communicated with the atomizing chamber is higher than the top end of the main body 121, so as to prevent more condensate from entering the air passage to some extent.

For the convenience of understanding, in the present embodiment, the second connecting groove is communicated with the first connecting groove 128 and is also shielded by the sealing member 14, so that the channel formed by the sealing member 14 shielding the second connecting groove is summarized as the gas channel, and of course, the channel formed by the sealing member 14 shielding the first connecting groove 128 and the second connecting groove is substantially the same channel.

In some embodiments, the first connecting groove 128 includes at least two connecting sections connected end to end, and the adjacent connecting sections are disposed at an angle, and the other end of the first connecting groove 128 extends to the top of the main body 121, that is, the first connecting groove 128 is bent, that is, the gas channel is also bent.

When the condensate enters the gas channel from the top, the bent gas channel can effectively slow down the downward flow of the condensate compared with the vertically extending gas channel, and after the flowing speed of the condensate is reduced, the condensate is easy to volatilize in the flowing process and cannot flow down continuously due to the fact that the condensate is easy to volatilize, so that the condensate is prevented from influencing the use of the microphone 16.

Further, there is at least one connection segment whose inlet end is located a distance from the top of the body 121 that is smaller than the outlet end.

It should be noted that one of the functions of the microphone 16 is to detect the number of times of smoking by the user, because when the microphone is used to suck the smoke, the smoke in the atomizing chamber is sucked, and the air channel is communicated with the atomizing chamber, so that a part of the air in the air channel is discharged, thereby forming a negative pressure in the air channel, and simultaneously forming a negative pressure in the accommodating chamber 122, and when the microphone 16 senses the negative pressure, the number of times of suction can be recorded, and the air inlet end and the air outlet end are also determined corresponding to the airflow direction when the suction is performed, specifically, the airflow direction flowing from the accommodating chamber 122 to the air channel.

And for the distance between the gas inlet end of the connecting section and the top to be smaller than the distance between the corresponding gas outlet end and the top, that is to say, the horizontal height of the gas inlet end of the connecting section is higher than that of the gas outlet end of the connecting section, and the condensate flows along the gas access and flows from the gas outlet end to the gas inlet end of the connecting section. Therefore, when more condensate enters the air channel, the condensate can be prevented from entering the microphone 16 in the accumulated air channel due to the connecting section with the higher level height of the air inlet end.

It is confirmed that in the above description of one function of the microphone 16, the microphone 16 detects the number of times the user sucks the smoke only by generating the negative pressure in the accommodating cavity 122, and the sucking amount of the user is relatively large, so that the negative pressure generated in the air passage is relatively large, and therefore, even if the condensate is accumulated in the air passage, the negative pressure can be generated in the accommodating cavity 122, thereby ensuring the detection accuracy of the microphone 16.

In some embodiments, the first connecting groove 128 includes a first vertical section, a bent section and a second vertical section sequentially connected end to end, an air inlet end of the horizontal section is connected to the through hole 124, a distance between an air inlet end of the bent section and the top of the main body 121 is smaller than a distance between an air outlet end of the bent section and the top of the main body 121, and an air outlet end of the second vertical section extends to the top of the main body 121.

It will be appreciated that the segments of the first connecting groove 128 may be considered directly as segments of the gas passage, for convenience of description in conjunction with the drawings. As described above, after the condensate enters the gas channel from the gas outlet, the condensate may accumulate in the bent section and the second vertical section because the horizontal height of the gas inlet end of the bent section is higher than that of the gas outlet end.

Of course, in other embodiments, as described above, as long as it is ensured that there is a connection section with a level of the air inlet end higher than that of the air outlet end, the specific arrangement form can be determined according to actual conditions.

In some embodiments, the sealing member 14 includes a connecting portion 142 and a flat portion 144, the connecting portion 142 is configured to be detachably connected to the top end of the main body 121, the flat portion 144 is fixedly connected to the connecting portion 142, and when the connecting portion 142 is connected to the top end of the main body 121, the flat portion 144 covers a side of the main body 121 away from the accommodating portion 123 to shield the first connecting groove 128.

Further, the connecting portion 142 covers the top end of the main body 121, the planar portion 144 covers the step surface 126, a plurality of clamping posts are arranged on the step surface 126 of the main body 121, a plurality of clamping holes corresponding to the clamping portions are formed in the planar portion 144, and the planar portion 144 is fixed relative to the step surface 126 through the matching of the clamping holes and the clamping posts.

Specifically, the sealing member 14 is a silicone sealing sleeve, and the connecting portion 142 is covered on the top end of the main body 121, that is, the connecting portion 142 having elasticity has a cavity with a variable volume, the top end of the main body 121 is accommodated in the cavity, and the connecting portion 142 having elasticity is tightened on the top end of the main body 121.

When the housing 11 is sleeved on the body 121, the planar portion 144 and the connecting portion 142 are further fixed on the body 121, and meanwhile, the connecting portion 142 is covered on the top end of the body 121, so the connecting portion 142 is clamped between the housing 11 and the body 121, and the housing 11 and the connecting portion 142 are matched to seal the atomization chamber.

In some embodiments, the vent 18 includes a resilient annular portion fixedly attached at one end thereof and a vent portion that is fitted over the microphone 16 to seal a gap between the microphone 16 and the side wall of the receiving cavity.

Further, the vent is located at an end of the microphone 16 facing the through hole 124, and is used for blocking condensate in the air passage from entering the microphone 16 and enabling air communication between the microphone 16 and the air passage.

In some embodiments, the elastic ring portion and the ventilation portion enclose to form a receiving cavity 182 for placing the microphone 16, the ventilation portion further defines a plurality of ventilation holes 184 communicating with the receiving cavity 182, and when the ventilation member 18 is disposed in the receiving cavity 122, the ventilation portion is pressed against the through holes 124 of the main body 121, so that the receiving cavity 182 communicates with the through holes 124 through the ventilation holes 184, and blocks off the condensate.

Further, the vent hole 184 is a through hole with a diameter not exceeding 8 mm, and the diameter not exceeding 8 mm can effectively block the passage of the condensate, but can allow the gas to flow, so as to prevent the condensate from entering under the condition of ensuring the normal operation of the microphone 16. Specifically, the diameter of the vent 184 is 8 mm to improve the ability of the air to circulate while ensuring the blocking of the condensate, thereby ensuring the accuracy of the detection of the microphone 16.

It should be explained that the provision of the meander-like air passage prevents condensate from entering the microphone 16 in most cases, but there is still a portion of condensate entering the bottom of the air passage, which condensate would affect the function of the microphone 16 if the microphone 16 were provided in the receiving chamber 122 alone, and thus the venting member 18 is provided.

Of course, in other embodiments, the venting portion does not have to be pressed against the through hole 124 of the main body 121, i.e. a part of the condensate entering the bottom of the air channel can enter the accommodating cavity 122, but only the condensate cannot enter the microphone 16.

In some embodiments, the vent 18 is a silicone microphone cover having a radial dimension greater than the radial dimension of the receiving cavity 122 when the silicone microphone cover is fitted over the microphone 16.

Specifically, the microphone 16 and the receiving portion 123 have a cylindrical shape, and the receiving cavity 122 has a cylindrical shape. Establish silica gel miaow head cover on miaow head 16, then fill in both and hold the chamber 122 in, because the radial dimension of silica gel miaow head cover this moment is greater than the radial dimension who holds chamber 122, the inner wall that also holds chamber 122 presss from both sides the silica gel miaow head cover with miaow head 16 tightly to ensure silica gel miaow head cover and hold the leakproofness between the chamber 122 inner wall.

It can be understood that when filling in holding chamber 122 with the miaow head 16 that the cover was equipped with the silica gel miaow head cover, the air vent 184 of silica gel miaow head cover is towards through-hole 124, and the condensate can't pass through air vent 184, and the condensate then need enter through the opening of opposite side in going into miaow head 16, but silica gel miaow head cover and hold and seal between the chamber 122 inner wall for the condensate can't enter into the opposite side, thereby can't enter into in the miaow head 16.

Referring to fig. 1 and 5, in some embodiments, the air channel structure further includes a circuit board 13, the circuit board 13 is disposed in the inner housing assembly, and the microphone 16 is mounted on the circuit board 13 and electrically connected to the circuit board 13. The circuit board 13 and the microphone 16 are matched to detect the suction frequency, which is a conventional technique in the art and therefore will not be described in detail.

But carry out the fixed of miaow head 16 portion 123 that holds relatively through adopting the silica gel miaow head cover, because the silica gel miaow head cover has certain elasticity, when there is certain error in the installation of miaow head 16 on circuit board 13, install back miaow head 16 promptly and hold the chamber 122 disalignment, just also make the circumference lateral wall of miaow head 16 and hold the distance between the circumference inner wall of chamber 122 not uniform, and have elastic silica gel miaow head cover then can ensure the centre gripping in miaow head 16 and hold between the chamber 122 inner wall, thereby realize miaow head 16 and hold the portion 123 fixed while also can guarantee and hold the leakproofness between the chamber 122 inner wall, and miaow head 16 installation on circuit board 13 allows to have certain error, the installation degree of difficulty has also been reduced.

It is understood that, in the above structure, the inner housing 12 should further include a housing structure, besides the main body 121, the accommodating portion 123 and the extending portion 125, connected to the main body 121, for forming an enclosing space with the main body 121, and the accommodating portion 123, the sealing member 18, the circuit board 13 and the like are disposed in the enclosing space.

Compared with the prior art, the utility model provides an air flue structure and electron cigarette have following advantage at least:

1) the condensate in the atomizing cavity is effectively prevented from entering the microphone through the gas channel, so that the scrapping of the battery rod is avoided, the service lives of the battery rod and the electronic cigarette are prolonged, and the use cost is reduced;

2) when the silica gel microphone sleeve is used for guaranteeing the sealing performance, certain errors can be caused in the microphone installation on the circuit board, the installation difficulty is reduced, and therefore the assembly cost is reduced.
