Definitions
- This application relates to the technical field of a smoking set, and in particular, to an electronic vaporization device.
- An electronic vaporization device that converts a nicotine-containing liquid aerosol-forming matrix into aerosol through heating and vaporization of a vaporization core is an electronic device that imitates a cigarette and has a smoke, a taste and a sensation similar to those of the cigarette.
- This nicotine-containing aerosol produced by vaporization does not contain harmful carcinogens such as tar, which is commonly found in ordinary cigarette smoke, and is considered a healthy alternative to the cigarette for a traditional smoker.
- this electronic vaporization device has good portability, does not produce an open flame, does not produce second-hand smoke, has environmental protection characteristics, and hence is preferred by many smokers.
- the problem with the electronic vaporization device in the related art is as follows: when the liquid aerosol-forming matrix is not used up, the electronic vaporization device tends to deteriorate and become tasteless if the electronic vaporization device is left for too long, reducing the user's vaping experience.
- This application provides an electronic vaporization device to solve the problem that the liquid aerosol-forming matrix in the electronic vaporization device in the related art tends to deteriorate and become tasteless.
- this application provides an electronic vaporization device, including:
- the liquid storage amount of the electronic vaporization device can be increased through the first storage unit and the second storage unit.
- the first liquid delivery channel and the second liquid delivery channel are configured to deliver the corresponding liquid to the vaporization unit at different times, that is, the first liquid delivery channel and the second liquid delivery channel deliver the first liquid and the second liquid to the vaporization unit at different times.
- the second liquid can be delivered after the first liquid is delivered, thereby prolonging the storage time of the second liquid and preventing deterioration and tastelessness.
- the first storage unit and the second storage unit are independent of each other so that the first liquid is not delivered to the second storage unit and the second liquid is not delivered to the first storage unit.
- the first storage unit and the second storage unit are independent of each other, so that the first liquid and the second liquid are not tainted by other odor each other when the first liquid and the second liquid have different flavors. If one of the liquids becomes tasteless and deteriorated, the liquid does not contaminate the other liquid.
- the first liquid delivery channel and the second liquid delivery channel are independent of each other so that the first liquid is not delivered through the second liquid delivery channel and the second liquid is not delivered through the first liquid delivery channel.
- the first liquid delivery channel and the second liquid delivery channel are partially shared so that the first liquid or the second liquid can be delivered through the shared portion of the liquid delivery channel.
- the first liquid delivery channel and the second liquid delivery channel are partially shared, which can save the internal space of the electronic vaporization device, with compact and reasonable structure design.
- the first liquid delivery channel and the second liquid delivery channel are opened or closed in an expected or predetermined manner.
- the first storage unit and the second storage unit are configured to be moved simultaneously to open or close the liquid delivery channel.
- the first storage unit and the second storage unit are configured to rotate about a length direction of the electronic vaporization device.
- At least a portion of the first liquid delivery channel and at least a portion of the second liquid delivery channel are configured to be moved simultaneously to open or close the liquid delivery channel.
- the electronic vaporization device further includes a switch component configured to open or close the liquid delivery channel.
- the first liquid delivery channel and the second liquid delivery channel are configured to be able to be closed simultaneously.
- the first liquid delivery channel and the second liquid delivery channel are arranged to be closed simultaneously, which on the one hand can realize the completely sealed form of the storage unit and avoid the phenomenon of oil leakage during long time storage and transportation or under an environment of high altitude and high pressure, and on the other hand can avoid contact with air and prevent the liquid from deterioration, tastelessness or volatilization.
- the first liquid delivery channel is configured to be in a normally open state.
- one of the liquid delivery channels is configured to be in the normally open state, which simplifies structural design on the one hand and opening operation on the other.
- the second storage unit is configured to be moved to open or close the second liquid delivery channel.
- the electronic vaporization device further includes a buffer unit.
- the first liquid or the second liquid is delivered to the vaporization unit through the buffer unit.
- the vaporization unit is at least partially placed in the buffer unit.
- the first storage unit and the second storage unit are fluidly communicated with each other.
- the first liquid can be delivered to the second storage unit and to the vaporization unit through the second liquid delivery channel, thereby forming the first liquid delivery channel.
- the first liquid delivery channel is opened in order after the second liquid delivery channel.
- the second liquid delivery channel is configured to be in the normally open state.
- the first storage unit is configured to be moved to open or close the first liquid delivery channel.
- the first liquid delivery channel can be conveniently opened or closed by the movement of the first storage unit.
- the first storage unit is configured to rotate about the length direction of the electronic vaporization device.
- the first storage unit is configured to be moved up and down along the length direction of the electronic vaporization device.
- the electronic vaporization device further includes an outer housing.
- the outer housing has at least one visual window through which the user can observe the amount of the liquid stored in the first storage unit and/or the second storage unit.
- first and second are used merely for the objective of description, and shall not be construed as indicating or implying relative importance or implicitly indicating a quantity of indicated technical features. Therefore, a feature defined by “first” or “second” can explicitly indicate or implicitly include at least one of such features.
- the technical solutions between the various embodiments can be combined with each other, but shall be based on what can be achieved by a person skilled in the art. When a combination of technical solutions is contradictory or cannot be achieved, it should be construed that such a combination of technical solutions does not exist, and also does not fall within the scope of protection required by the present disclosure.

- As shown in
FIG. 1 to FIG. 2 , anelectronic vaporization device 10 includes a suction nozzle 11, anouter housing 12, anoil tank cover 13, anoil tank shell 14, anoil tank shell 15, anoil tank shell 18, a connectingmember 16, a sealingmember 17, a sealingmember 19, avaporization unit 20, avaporization seat 21, abattery 22, a fixingmember 23, anairflow sensor 24, and abottom base 25.
theouter housing 12 is cylindrical and hollow inside. Theouter housing 12 has an upper open end and a lower open end. One end of the suction nozzle 11 can be fixed in the upper open end. One end of thebottom base 25 can be fixed in the lower open end, thus forming a receiving space. Components such as theoil tank cover 13, theoil tank shell 14, theoil tank shell 15, theoil tank shell 18, the connectingmember 16, the sealingmember 17, the sealingmember 19, thevaporization unit 20, thevaporization seat 21, thebattery 22, the fixingmember 23, and theairflow sensor 24 are provided in the receiving space. - The
oil tank shell 14 and theoil tank shell 15 have an open end and a liquid outlet. Theoil tank shell 18 has an upper open end and a lower open end. The open ends of theoil tank shell 14 and theoil tank shell 15 are sealed partially by theoil tank cover 13. The liquid outlets of theoil tank shell 14 and theoil tank shell 15 are connected to the upper open end of theoil tank shell 18 via the connectingmember 16. Thevaporization seat 21 is arranged at the lower open end of theoil tank shell 18. The sealingmember 17 is provided between the liquid outlets of theoil tank shell 14 and theoil tank shell 15 as well as the connectingmember 16. The sealingmember 19 is provided between thevaporization seat 21 and the lower open end of theoil tank shell 18. - The
vaporization seat 21 is provided with an air inlet. Theelectronic vaporization device 10 also includes an airflow channel. The airflow channel extends from the air inlet of thevaporization seat 21 to the outlet end of the suction nozzle 11 (shown by a dashed arrow A in the figure). In this example, the airflow channel is formed by anupper pipe 26, alower pipe 27, and the connectingmember 16. One end of theupper pipe 26 is fixed in a through hole of theoil tank cover 13, and the other end of theupper pipe 26 is fixed in the connectingmember 16. One end of thelower pipe 27 is fixed to the connectingmember 16, and the other end of thelower pipe 27 is fixed to the sealingmember 19. The sealingmember 19 is provided with an airflow through hole. Thus, an airflow flows from an air inlet, passes through the airflow through hole of the sealingmember 19, thelower pipe 27, the connectingmember 16, and theupper pipe 26, and flows out of the outlet end of the suction nozzle 11. - A first storage unit is formed among the inner surface of the
oil tank shell 14, a part of theoil tank cover 13, and the liquid outlet of theoil tank shell 14 for storing the first liquid. A second storage unit is formed among the inner surface of theoil tank shell 15, a part of theoil tank cover 13, and the liquid outlet of theoil tank shell 15 for storing the second liquid. A buffer unit is formed among the inner surface of theoil tank shell 18, the outer surface of thelower pipe 27, and the connectingmember 16 for buffer the first liquid or the second fluid. It can be understood that the two storage units are arranged, which can increase the liquid storage amount of theelectronic vaporization device 10. In this example, only the first storage unit and the second storage unit are shown about a length direction of the electronic vaporization device 10 (the direction shown by the dashed arrow A in the figure). It is easily conceivable that more than two storage units can be provided about the length direction of theelectronic vaporization device 10. - The compositions of the first liquid and the second liquid can be the same or different. The liquid can be a liquid containing a tobacco-containing substance containing a volatile tobacco flavor component, and can also be a liquid containing a non-tobacco substance. For example, the liquid can include a mixture of water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin. The flavor can include menthol, mentha piperita, spearmint oil, various fruit flavoring ingredients, but are not limited thereto. The flavoring agent can include ingredients that can provide a user with a variety of scents or relishes. The vitamin mixture can be a substance mixed with at least one of, but not limited to, vitamin A, vitamin B, vitamin C and vitamin E. Alternatively, the liquid can include an aerosol-forming agent such as glycerol and propylene glycol.

Theheating element 202 is spirally provided on the inner surface of theliquid delivery unit 201 or embedded in theliquid delivery unit 201. Thelead wire 203 and thelead wire 204 are connected to one end of theheating element 202, respectively, for coupling with thebattery 22 provided under thevaporization seat 21. It will be understood that both the sealingmember 19 and thevaporization seat 21 are provided with via holes of thelead wire 203 and thelead wire 204. - The
vaporization unit 20 is provided in thelower pipe 27. Thelower pipe 27 is provided with a liquid inlet. In this way, the first liquid and/or the second liquid, bufferd by the buffer unit, flows into or is delivered to thevaporization unit 20 via the liquid inlet. After being energized, theheating element 202 heats the liquid delivered by theliquid delivery unit 201 to generate aerosol for the user to inhale. The aerosol flows out of the outlet end of the suction nozzle 11 when the airflow of the airflow channel flows through the inner surface of the pipe-shapedliquid delivery unit 201. To be sure, thevaporization unit 20 is not limited to this form. For example: theliquid delivery unit 201 can be placed across the airflow channel with two ends in theoil tank shell 18. Theheating element 202 is spirally wound on theliquid delivery unit 201. For example: thevaporization unit 20 includes a common porous substrate in the related art and a heat producing element printed on the porous substrate. The porous substrate delivers the first liquid and/or the second liquid bufferd by the buffer unit to the heat producing element. The porous substrate can be plate-shaped, pipe-shaped, and the like. - To be understood in conjunction with
FIG. 4-FIG. 7 that the connectingmember 16 includes anouter pipe 161. Theouter pipe 161 is closed at one end and opened at the other end. The connectingmember 16 further includes anouter pipe 162 extending from the closed end of theouter pipe 161 toward thevaporization seat 21. Theouter pipe 162 has an outer diameter smaller than that of theouter pipe 161 so as to form astep surface 1611 at the closed end of theouter pipe 161. The connectingmember 16 further includes aninner pipe 163. Theinner pipe 163 passes through the closed end of theouter pipe 161. The inner surface of theinner pipe 163 forms a part of the airflow channel. Theupper pipe 26 is inserted at one end of theinner pipe 163. Thelower pipe 27 is inserted at the other end of theinner pipe 163. The closed end of theouter pipe 161 also has a liquid throughhole 164 and a liquid throughhole 165. Both the liquid throughhole 164 and the liquid throughhole 165 are located between the outer surface of theinner pipe 163 and the inner surface of theouter pipe 162. The sealingmember 17 includes anouter pipe 171, aninner pipe 172, and an extending portion extending from the outer surface of theinner pipe 172 to the inner surface of theouter pipe 171. One end of the extending portion is recessed to form a receivingspace 173, and the other end of the extending portion has a protruding sealingportion 174. The sealingmember 17 further includes a liquid throughhole 175 passing through the extending portion. - When assembled, the liquid outlets of both the
oil tank shell 14 and theoil tank shell 15 are received between the inner surface of theouter pipe 161 and the outer surface of theinner pipe 163. The upper open end of theoil tank shell 18 abuts against thestep surface 1611. The sealingmember 17 is also provided between the inner surface of theouter pipe 161 and the outer surface of theinner pipe 163. Theinner pipe 163 is inserted in theinner pipe 172, so that a gap between the liquid outlets of theoil tank shell 14 and theoil tank shell 15 as well as the connectingmember 16 is sealed with the sealingmember 17. The liquid outlet of theoil tank shell 14 is aligned with and fluidly communicated with the liquid throughhole 175 and the liquid throughhole 165. The liquid outlet of theoil tank shell 15 is aligned with the sealingportion 174 and the liquid throughhole 164. The liquid throughhole 164 is sealed with the sealingportion 174. - After assembled, the first liquid stored in the first storage unit flows into the buffer unit through the liquid outlet of the
oil tank shell 14, the liquid throughhole 175, and the liquid throughhole 165, and then flows into thevaporization unit 20 through the liquid inlet of thelower pipe 27, thus forming a first liquid delivery channel. Because the liquid throughhole 164 is sealed with the sealingportion 174, the second liquid stored in the second storage unit cannot flow into the liquid throughhole 164 and thus cannot flow into the buffer unit and thevaporization unit 20. - After assembled, the airflow channel, the sealing
member 17, the connectingmember 16, and theoil tank shell 18 are fixed. However, the suction nozzle 11, the first storage unit, and the second storage unit can all rotate simultaneously about the length direction of the electronic vaporization device 10 (in the direction shown by the dashed arrow A in the figure). Specifically, the liquid outlets of theoil tank shell 14 and theoil tank shell 15 are moved circumferentially along the annular surface of the receivingspace 173. In practice, the user can hold the suction nozzle 11 to rotate the suction nozzle by 180° counterclockwise or clockwise so that the liquid outlet of theoil tank shell 15 is aligned with and fluidly communicated with the liquid throughhole 175 and the liquid throughhole 165. The liquid outlet of theoil tank shell 14 is aligned with the sealingportion 174 and the liquid throughhole 164. The liquid throughhole 164 is sealed with the sealingportion 174. After operation, the second liquid stored in the second storage unit flows into theoil tank shell 18 through the liquid outlet of theoil tank shell 15, the liquid throughhole 175, and the liquid throughhole 165, and in turn flows into thevaporization unit 20 through the liquid inlet of thelower pipe 27, thus forming a second liquid delivery channel. Because the liquid throughhole 164 is sealed with the sealingportion 174, the first liquid stored in the first storage unit cannot flow into the liquid throughhole 164, and thus cannot flow into theoil tank shell 18 and thevaporization unit 20. The suction nozzle 11 is held again and rotated by 180° counterclockwise or clockwise to return to an initial state. - Further, a
visual window 121 and avisual window 122 can be provided on theouter housing 12. The storage amount of the first liquid stored in theoil tank shell 14 can be observed through thevisual window 121. The storage amount of the liquid bufferd in theoil tank shell 18 can be observed through thevisual window 122. When the first liquid stored in the first storage unit is used up, the suction nozzle 11 is held again and rotated by 180° counterclockwise or clockwise to open the second liquid delivery channel so that the second liquid stored in the second storage unit is used. In this way, the first liquid delivery channel and the second liquid delivery channel are opened in turn so that the first liquid delivery channel and the second liquid delivery channel deliver the first liquid and the second liquid to the vaporization unit at different times. Before not used, the second liquid stored in the second storage unit is always in a sealed state, does not come into contact with air, is not deteriorated and become tasteless. - It can be known from the above description that the first liquid delivery channel and the second liquid delivery channel are partially shared, i.e., both share the liquid through
hole 175, the liquid throughhole 165, the buffer unit, and the liquid inlet of thelower pipe 27. However, both the first liquid and the second liquid flow into the common liquid delivery channel through different liquid outlets. The first liquid stored in the first storage unit cannot be delivered to the second storage unit. The second liquid stored in the second storage unit cannot be delivered to the first storage unit, i.e., the first storage unit and the second storage unit are independent of each other. Therefore, the first liquid and second liquid are not tainted by other odor with each other when the first liquid and second liquid have different flavors. If one of the liquids becomes tasteless and deteriorated, the liquid does not contaminate the other liquid. In other examples, it is feasible that the buffer unit is not arranged. In other examples, it is feasible for the first liquid delivery channel and the second liquid delivery channel not to have the common liquid delivery channel, i.e., the first liquid delivery channel and the second liquid delivery channel are independent of each other. The first liquid is not delivered through the second liquid delivery channel. The second liquid is not delivered through the first liquid delivery channel. In this way, the storage unit and the vaporization unit are fluidly communicated with each other through the separate liquid delivery channels. - From the above description, it can be learned that the first storage unit and the second storage unit are moved simultaneously. In other examples, it is also feasible that the first storage unit and the second storage unit are moved at different times. The first storage unit is first moved to open or close the first liquid delivery channel. The second storage unit is then moved to open or close the second liquid delivery channel. At this point, the first liquid delivery channel and the second liquid delivery channel can be opened or closed in an expected or predetermined manner. For example, initially, the first liquid delivery channel and the second liquid delivery channel are both in a closed state. The first storage unit is moved first to open the first liquid delivery channel (the second liquid delivery channel is in the closed state). After the first liquid is used up, the second storage unit is moved to open the second liquid delivery channel (the first liquid delivery channel can or cannot be closed). It is conceivable that the first liquid delivery channel and the second liquid delivery channel can be opened or closed in an expected or predetermined manner, which is not limited to those listed above, as long as the first liquid delivery channel and the second liquid delivery channel deliver the first liquid and the second liquid to the vaporization unit at different times.
- From the above description, it can be learned that the first storage unit and the second storage unit are moved simultaneously so that the first liquid delivery channel and the second liquid delivery channel are opened or closed. In other examples, it is also feasible that at least a portion of the first liquid delivery channel and at least a portion of the second liquid delivery channel are configured to be moved simultaneously to open or close the liquid delivery channel. Taking a structure shown in
FIG. 2 as an example, with a reasonable structural design, the connectingmember 16 is moved to open or close the liquid delivery channel. - From the above description, it can be learned that the first storage unit and the second storage unit are moved simultaneously so that the first liquid delivery channel and the second liquid delivery channel are opened or closed. In other examples, one switch component can be provided in the first liquid delivery channel and the second liquid delivery channel to open or close the first liquid delivery channel and the second liquid delivery channel. For example: a moving component is provided between the connecting
member 16 and theoil tank shell 18. Theouter housing 12 is provided thereon with an operating portion through which the moving component can be controlled to open or close the liquid delivery channel. It is easily conceivable and also feasible that the two moving components are arranged to open or close the first liquid delivery channel and the second liquid delivery channel, respectively. - From the above description, it can be learned that when the first storage unit and the second storage unit are moved simultaneously, one of the first liquid delivery channel and the second liquid delivery channel is open, and the other of the first liquid delivery channel and the second liquid delivery channel is closed. In other examples, the first liquid delivery channel and the second liquid delivery channel are configured to be able to be closed simultaneously. For example: initially, both the first liquid delivery channel and the second liquid delivery channel are both in the closed state. When the first liquid in the first storage unit needs to be used, the first storage unit and the second storage unit are moved simultaneously. When the first liquid delivery channel is opened, the second liquid delivery channel is still in the closed state. After the first liquid in the first storage unit is used up, the first storage unit and the second storage unit are moved simultaneously. The second liquid delivery channel is opened. The first liquid delivery channel is closed. After the first storage unit and the second storage unit are moved simultaneously again, the first liquid delivery channel and the second liquid delivery channel are both closed.
- From the above description, it can be learned that the common liquid delivery channel is in a normally open state. The first liquid delivery channel is also in an open state. The moving travel of the first storage unit has a position for opening the first liquid delivery channel (e.g., rotating for a second time by 180° counterclockwise or clockwise), and a position for closing the first liquid delivery channel (e.g., rotating for a first time by 180° counterclockwise or clockwise). The moving travel of the second storage unit has a position for opening the second liquid delivery channel (e.g., rotating for a first time by 180° counterclockwise or clockwise), and a position for closing the second liquid delivery channel (e.g., rotating for a second time by 180° counterclockwise or clockwise). In other examples, it is also feasible for the first liquid delivery channel to be in the normally open state. In this case, the second storage unit can be only moved so that the second liquid delivery channel can be opened or closed.
- From the above description, it can be learned that the first storage unit and the second storage unit are moved simultaneously. In other examples, the first storage unit and the second storage unit are not moved. It is also feasible to move the buffer unit. Alternatively, it is feasible that the
vaporization unit 20 is moved. - The
battery 22 provides power to theelectronic vaporization device 10. Thebattery 22 can be a disposable battery. The capacity of thebattery 22 needs to be designed to be sufficient to meet the needs of the heating and vaporization of the first liquid and the second liquid. In other examples, thebattery 22 can also be a rechargeable battery. - The fixing
member 23 is fixed to thebottom base 25. The fixingmember 23 is configured to fix theairflow sensor 24. Referring back toFIG. 1 , thebottom base 25 has anair inlet 251. The airflow flows into and through theairflow sensor 24 through theair inlet 251. Theairflow sensor 24 can sense and feed sensing signals to a circuit board (not shown), thus in turn controlling the heating of thevaporization unit 20. -
FIG. 1 to FIG. 7 are described with two storage units as an example. It is also mentioned in the preceding text that it is feasible to set more than two storage units. For better understanding, the following is described in conjunction withFIG. 8 . - As shown in
FIG. 8 , theelectronic vaporization device 10 includes four storage units a, b, c, and d. All of the four storage units are arranged around the airflow channel f. The specific structures of the storage unit and the airflow channel can be referred in the foregoing contents. In this example, the four storage units are all independent of each other. Each of the storage units is fluidly communicated with the vaporization unit through at least one of the liquid delivery channels. For ease of description, each of the storage units a1, b1, c1, and d1 is fluidly communicated with the vaporization unit through one liquid delivery channel. Similar to the foregoing, the four liquid delivery channels deliver the liquid to the vaporization unit at different times and can be opened or closed in an expected or predetermined manner. For example: the storage units a1, b1, c1, and d1 are opened in the order of a1, b1, c1, and d1. Alternatively, the storage unit a1 is first opened. The storage unit b1 is then opened. The storage units c1 and d1 are opened simultaneously. Alternatively, the storage units a1 and b1 are opened simultaneously, and then the storage units c1 and d1 are opened simultaneously. Alternatively, the storage unit a1 is first opened, and then the storage units b1, c1, and d1 are opened simultaneously. - Referring to
FIG. 9 , unlike embodiments ofFIG. 1 to FIG. 7 ,
in this example, theelectronic vaporization device 10 only includes anoil tank shell 214 and anoil tank shell 215. Theupper pipe 26 is integrally formed with theoil tank shell 214. The first storage unit is formed among theoil tank cover 13, the inner surface of theoil tank shell 214, and the liquid outlet of theoil tank shell 214 for storing the first liquid. A second storage unit is formed among the connectingmember 16, the inner surface of theoil tank shell 215, the outer surface of thelower pipe 27, and the sealingmember 19 for storing the second fluid. - In this example, the first liquid stored in the first storage unit flows into the second storage unit through the liquid outlet of the
oil tank shell 214, the liquid throughhole 175, and the liquid throughhole 165, and in turn flows into thevaporization unit 20 through the liquid inlet of thelower pipe 27, thereby forming the first liquid delivery channel (shown in B and C of the figure). The second liquid stored in the second storage unit flows into thevaporization unit 20 through the liquid inlet of thelower pipe 27, thus forming the second liquid delivery channel (shown in C in the figure). That is, the second liquid delivery channel is a part of the first liquid delivery channel. - In this example, the
oil tank shell 215 is fixed, and the second liquid delivery channel is in the normally open state. The first storage unit can rotate about the length direction of the electronic vaporization device 10 (in the direction shown by the dashed arrow A in the figure). The moving travel of the first storage unit can have a position for opening the first liquid delivery channel (rotating by 180° counterclockwise or clockwise) and a position for closing the first liquid delivery channel (rotating by 180° counterclockwise or clockwise). In use, the second liquid delivery channel is first in an open state. The first liquid delivery channel is opened after the second liquid stored in the second storage unit is used up.FIG. 8 shows a situation after the first liquid delivery channel is opened. - Referring to
FIG. 10 , unlike the embodiment ofFIG. 9 ,
theelectronic vaporization device 10 includes anoil tank shell 314, anoil tank shell 315, a first connectingmember 3161, a second connectingmember 3162, afirst sealing member 3171, and asecond sealing member 3172. Theoil tank shell 314 is connected to theoil tank shell 315 via the first connectingmember 3161 and the second connectingmember 3162. One end of the first connectingmember 3161 is inserted in the second connectingmember 3162. A gap between the first connectingmember 3161 and theoil tank shell 314 is sealed with thefirst sealing member 3171. A gap between the first connectingmember 3161 and the second connectingmember 3162 is sealed with thesecond sealing member 3172. - The suction nozzle 11, the
upper pipe 26, and theoil tank shell 314 are integrally formed. The first storage unit is formed between the inner surface of theoil tank shell 314 and the liquid outlet of theoil tank shell 214 for storing the first liquid. A second storage unit is formed among the connectingmember 3162, the inner surface of theoil tank shell 315, the outer surface of thelower pipe 27, and the sealingmember 19 for storing the second fluid. - After assembled, the
first sealing member 3171, the second connectingmember 3162, and theoil tank shell 315 are fixed. Theoil tank shell 314, thefirst sealing member 3171, and the first connectingmember 3161 are moved up and down, i.e., moved along the length direction of theelectronic vaporization device 10. When the first connectingmember 3161 is moved downward a certain distance, an oil guide hole provided on the side wall of the first connectingmember 3161 is fluidly communicated with the second storage unit that stores the second liquid.FIG. 9 shows a situation when the first liquid delivery channel is not opened. - To be sure, a preferred embodiment of this application is given in the specification of this application and the accompanying drawings.
