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. 1-3, an embodiment of the present invention provides an electronic cigarette 100, which includes an oil storage tube 10, a nozzle cover 20, and a housing 30.

The oil storage pipe 10 is provided with a first end 11 and a second end 13 which are opposite to each other and a circumferential side surface connected between the first end 11 and the second end 13, the second end 13 is provided with a vent hole 19 (see fig. 6), the circumferential side surface of the oil storage pipe 10 is provided with an air inlet groove 12(14), the air inlet end of the air inlet groove 12(14) is arranged close to the first end 11, and the air outlet end of the air inlet groove 12(14) extends to the second end 13;

the suction nozzle cover 20 and the outer shell 30 are respectively sleeved outside the first end 11 and the second end 13 of the oil storage pipe 10, the suction nozzle cover 20 is provided with an air inlet 22 corresponding to the air inlet end of the air inlet groove 12(14), and the outer shell 30 is covered on the oil storage pipe 10 to cover the air inlet groove 12 (14).

The outer shell 30 and the second end 13 of the oil storage pipe 10 enclose to form an air inlet cavity, and the vent hole 19 is communicated with the air outlet end of the air inlet groove 12(14) through the air inlet cavity.

By arranging the electronic cigarette, the outside air enters from the air inlet hole 22 and then enters the air inlet cavity through the

air inlet grooves

12 and 14, namely the second end 13 of the oil storage pipe 10, namely the bottom of the atomizer in practical application, and the air flowing to the second end 13 of the oil storage pipe 10 finally enters the oil storage pipe 10 from the vent hole 19. Compare in traditional mode of admitting air, this mode of admitting air is not influenced by the clearance between battery pole and the atomizer, also does not receive the machining error influence of both, and the bottom that enters into the atomizer from inlet channel promptly is difficult to receive the influence of atomizer and battery pole, and the airflow that enters into in the atomizer in the different electron cigarette products can not have great difference, and the resistance-suction that the user experienced when guaranteeing the user suction is the same, improves user's experience.

It should be noted that the resistance to suction felt by the user can be interpreted as: the user provides a suction force, the air flow of the electronic cigarette is limited, when the user sucks, the negative pressure is generated in the mouth of the user to generate suction force, the maximum air flow which can be provided by the electronic cigarette cannot compensate the negative pressure generated in the mouth of the user, and the user feels a force which hinders the suction force, and the force which hinders the suction force is suction resistance. Meanwhile, it can be understood that a certain suction resistance can effectively improve the smoking experience of the user.

In addition, processing errors are inevitable, and for a traditional air inlet mode, the battery rod and the atomizer need to be controlled to ensure that a gap between the battery rod and the atomizer is stable after the battery rod and the atomizer are installed, and in such a case, the difficulty of ensuring the error to be smaller than an allowable range is high; and adopt the utility model provides an air inlet mode only needs to set up air inlet duct 12(14) on the oil storage pipe surface, set up on suction nozzle lid 20 simultaneously correspond air inlet duct 12(14) inlet end can, control machining error more easily. In other words, use the user to inhale the electron cigarette product that hinders to feel satisfied for the electron cigarette and be the yields, unsatisfactory is nonconforming product, then can understand the utility model provides a mode yields is higher.

Referring to fig. 4, in some embodiments, when the housing 30 and the nozzle cover 20 are respectively sleeved on the first end 11 and the second end 13 of the oil storage tube 10, the housing 30 and the nozzle cover 20 can enclose to form an inner cavity, the oil storage tube 10 is disposed in the inner cavity, and the air inlet groove 12(14) formed on the oil storage tube 10 cooperates with the inner wall of the inner cavity to form an air inlet channel.

It should be explained that the groove is a structure with two convex sides and a concave middle part, and the

air inlet grooves

12 and 14 form a passage with the inner wall of the inner cavity, which means that the convex sides of the

air inlet grooves

12 and 14 abut against the inner wall of the inner cavity, that is, cover the

air inlet grooves

12 and 14, thereby forming an air inlet passage.

Meanwhile, the nozzle cover 20 and the housing 30 are both sleeved outside the oil storage pipe 10, and the nozzle cover 20 and the housing 30 both cover the air inlet grooves 12(14), that is, the air inlet channel is not only the part covered by the housing 30, but also the air inlet grooves 12(14) covered by the housing 30 form the air inlet channel.

Further, the oil storage tube 10 is substantially rectangular, the nozzle cover 20 and the housing 30, which are correspondingly fitted over the oil storage tube 10, are also substantially rectangular to match the oil storage tube 10, and both the nozzle cover 20 and the housing 30 are open to fit over the oil storage tube 10.

In practical application, when the suction nozzle cover 20 and the outer casing 30 are sleeved on the oil storage pipe 10, the open end of the suction nozzle cover 20 and the open end of the outer casing 30 are smoothly arranged, and the open ends of the two are abutted. Thus, the two smooth opening ends are abutted, and the sealing performance can be ensured to a certain extent.

It should be noted that, because of inevitable manufacturing errors, a slight gap may exist between the nozzle cover 20 and the housing 30, and a slight gap may also exist between the position where the oil storage tube 10 abuts against the inner wall of the inner cavity and the inner wall of the inner cavity, and although the gap may allow gas to pass through, the gas entering the air inlet cavity is still mainly entering through the air inlet channel, and the gas entering through the gap is practically negligible.

In some embodiments, the circumferential side surface of the oil storage tube 10 includes a first side 15 and a second side 17 which are oppositely arranged, the first side 15 and the second side 17 are both provided with air inlet grooves 12(14), and the suction nozzle cover 20 is provided with at least two air inlet holes 22 corresponding to the air inlet ends of the air inlet grooves 12(14) on the first side 15 and the second side 17.

In some embodiments, the nozzle cover 20 is detachably connected to the oil reservoir tube 10. Further, the outer casing 30 is detachably connected to the oil reservoir pipe 10, in conjunction with the above-described embodiment, that is, the open ends of the nozzle cover 20 and the outer casing 30 are abutted when both the nozzle cover 20 and the outer casing 30 are connected to the oil reservoir pipe 10.

In practical application, for the nozzle cover 20, the first side 15 and the second side 17 of the oil storage tube 10 are both provided with a clamping protrusion 16, and when the nozzle cover 20 is sleeved on the oil storage tube 10, the air inlet 22 of the nozzle cover 20 is clamped in the clamping protrusion 16. The housing 30 may be relatively fixedly sleeved on the oil storage tube 10 in a clamping manner, or may be directly sleeved on the oil storage tube 10. Therefore, the air inlet hole 22 has two purposes, and other hole positions do not need to be formed on the suction nozzle cover 20, so that the integrity of the appearance of the product is ensured.

It should be noted that, as shown in the figure, the clamping protrusion 16 is clamped to the air inlet hole 22 to prevent the nozzle cover 20 from being separated from the oil storage tube 10, and the nozzle cover 20 is movable toward the second end 13 of the oil storage tube 10, and when the outer shell 30 is also relatively fixedly connected to the oil storage tube 10, the open end of the outer shell 30 just abuts against the open end of the nozzle cover 20, so as to fix the nozzle cover 20.

Referring to fig. 2, in some embodiments, the

air inlet grooves

12 and 14 include two first air inlet grooves 12 opened on the first side 15, the air inlet holes 22 include first air inlet holes 22 opened on the nozzle cover 20 corresponding to the first side 15, and the first air inlet holes 22 are disposed corresponding to the air inlet ends of the two first air inlet grooves 12 and are simultaneously communicated with the two first air inlet grooves 12.

Further, the suction nozzle cover 20 and the housing 30 cover the two first air inlet grooves 12 to form two first air inlet channels, the air outlet ends of the first air inlet channels are communicated with the air inlet cavity, and the air flow areas of the two first air inlet channels are larger than the air flow areas of the first air inlet holes 22.

In practical applications, the air inlet ends of the two first air inlet grooves 12 are communicated, and as shown in the figure, the two first air inlet grooves 12 formed on the first side 15 are substantially formed into a U-shaped groove, and the U-shaped groove can be equally divided into the two communicated first air inlet grooves 12, so that the air inlet ends of the two first air inlet grooves 12 are simultaneously arranged corresponding to the first air inlet holes 22.

It should be explained that the gas flow areas of the two first intake passages being larger than the gas flow area of the first intake port 22 means that the total gas flow area of the two intake passages is larger than the gas flow area of the first intake port 22. Thus, when the nozzle cover 20 is manufactured, the flow of the gas can be controlled by controlling the size of the first air inlet hole 22, and the suction resistance can be adjusted, so that the user experience is ensured.

Referring to fig. 3, in some embodiments, the

air inlet grooves

12 and 14 further include a second air inlet groove 14 disposed on the second side 17, the air inlet holes 22 further include a second air inlet hole 22 disposed on the nozzle cover 20 corresponding to the second side 17, and the second air inlet hole 22 is disposed corresponding to an air inlet end of the second air inlet groove 14.

Further, the suction nozzle cover 20 and the housing 30 cover the second air inlet groove 14 to form a second air inlet channel, an air outlet end of the second air inlet channel is communicated with the air inlet cavity, and an air flow area of the second air inlet channel is larger than that of the second air inlet hole 22.

It can be understood that the gas flow area of the second air inlet channel is larger than the gas flow area of the second air inlet hole 22, so as to control the flow rate of the gas by controlling the size of the second air inlet hole 22 when the nozzle cover 20 is manufactured, and further adjust the suction resistance, thereby ensuring the user experience.

Of course, in other embodiments, the number of the second air inlet grooves 14 on the second side 17 may also be two, and two second air inlet channels are correspondingly formed, so that it is only required to ensure that the total air flow area of the two second air inlet channels is larger than the air flow area of the second air inlet hole 22.

In some embodiments, for a substantially rectangular parallelepiped oil reservoir tube 10, the first side 15 and the second side 17 refer to two sides that extend along the longitudinal direction of the oil reservoir tube 10 but have a smaller surface area, and the first end 11 and the second end 13 refer to two ends of the oil reservoir tube 10 in the longitudinal direction.

Referring to fig. 4, in some embodiments, the electronic cigarette further includes a microphone assembly 40, the housing 30 is an open structure, the microphone assembly 40 is disposed in the housing 30, and the housing 30 is further provided with a battery 60, and the housing 30 is sleeved on the oil storage tube 10 and then surrounds the second end 13 of the oil storage tube 10 to form an air inlet cavity, in fact, the housing 30, the oil storage tube 10 and the microphone assembly 40 surround to form the air inlet cavity, and the microphone airway in the microphone assembly 40 is communicated with the air inlet cavity.

The size of the inlet chamber is related to the distance between the head module 40 and the second end 13 of the reservoir tube 10, whereas in practical applications, the distance between the head module 40 and the second end 13 is relatively small, which means that there is a gap between the head module 40 and the second end 13, which is the inlet chamber, i.e. the volume of the inlet chamber is relatively small. So, when the user aspirates, the intracavity of admitting air forms the negative pressure easily, corresponds also to form the negative pressure easily in the miaow head air flue with the chamber intercommunication of admitting air to ensure the sensitivity of miaow head.

It should be noted that the battery 60 and the microphone assembly 40 are disposed in the housing 30 and have a certain gap with the second end 13 of the oil storage tube 10, and the composition of the microphone assembly 40 and the manner of disposing the battery 60 and the microphone assembly 40 are conventional techniques well known to those skilled in the art, and therefore, detailed descriptions thereof are omitted.

Referring to fig. 5 and fig. 6, in some embodiments, the electronic cigarette further includes an atomizing core 51, the oil storage tube 10 further has an accommodating cavity 18 for accommodating the atomizing core 51, and the vent 19 is respectively communicated with the atomizing core 51 and the air inlet cavity.

Furthermore, the first end 11 of the oil storage tube 10 further has an air outlet communicated with the accommodating cavity 18, and an air outlet hole 24 communicated with the air outlet and the outside is formed at an end of the suction nozzle cover 20 corresponding to the first end 11. In practical application, the electronic cigarette further comprises a sealing gasket 53 and a vent pipe 52, wherein the sealing gasket 53 is arranged at the air outlet of the oil storage pipe 10, one end of the vent pipe 52 is communicated with the atomizing core 51, and the other end of the vent pipe 52 penetrates through the sealing gasket 53 and is communicated with the air outlet 24.

Thus, a complete gas flow path is formed, i.e. gas enters from the gas inlet hole 22 and then enters the gas inlet cavity via the gas channel, and the gas entering the gas inlet cavity enters from the vent hole 19 into the atomizing core 51, and then is conveyed to the gas outlet through the vent pipe 52 and is discharged from the gas outlet hole 24, and the discharged gas is sucked by the user.

It should be noted that the atomized liquid is stored in the accommodating cavity 18 of the oil storage tube 10, an oil filler hole for injecting the atomized liquid is further formed in the oil storage tube 10, an oil filler plug 54 for sealing the oil filler hole is arranged at the oil filler hole, the atomizing core 51 is communicated with the air vent 19, meanwhile, the air vent 19 can be sealed, the sealing gasket 53 is also used for sealing the oil storage tube 10 by matching with the air vent tube 52, the atomized liquid stored in the accommodating cavity 18 can flow into the atomizing core 51 through the liquid inlet hole formed in the air vent tube 52, and other positions are sealed.

In some embodiments, the number of the vent holes 19 is multiple, and the arrangement of the vent holes 19 ensures that the aperture of the vent holes 19 is small to avoid large particles from entering the atomizing core 51.

Further, the total gas flow area of a plurality of air vents 19 is greater than the gas flow area of inlet 22, namely is greater than the total gas flow area of both first inlet 22 and second inlet 22, so, the gas flow that gets into atomizing core 51 when further guaranteeing the user's suction can directly be adjusted through the size of adjusting inlet 22, makes things convenient for the control error, is convenient for make to form suitable resistance to draw, guarantee user's suction experience.

In addition, when the user sucks, can produce a negative pressure in the air intake chamber earlier, and because the total gas flow area of two inlet ports 22 is less than the total gas flow area of a plurality of air vents 19, also make the two inlet ports 22 of negative pressure that produce in the air intake chamber get into the gas chamber can not supply in time, the gas flow of suction promptly is greater than the gas flow that inlet port 22 got into, can guarantee so to produce the negative pressure in the miaow head passageway with air intake chamber intercommunication, thereby make the miaow head start normally, guarantee the sensitivity of miaow head.

In practice, the total gas flow area of the plurality of vent holes 19 is smaller than the total gas flow area of the plurality of inlet channels. It can be understood that, can store up certain air quantity when initial in many inlet channels, the user is when the suction, and many inlet channels's total gas flow area is greater than the total gas flow area of a plurality of air vents 19, just also realizes that the gas in many inlet channels can not all be through a plurality of air vents 19 in the twinkling of an eye, also can not be inhaled completely in the twinkling of an eye to ensure the smoothness of user's suction, in order to guarantee the experience of user's suction.
