Another example: the atomizing unit 20 includes a conventional porous substrate and a heating element printed on the porous substrate, and the porous substrate transfers the first liquid and/or the second liquid buffered by the buffer unit to the heating element, The porous substrate may be plate-like, tubular, or the like.

Please understand with reference to FIGS. 4 to 7 , the connector 16 includes an outer tube 161 , one end of the outer tube 161 is closed and the other end is open. The connector 16 also includes an outer tube 162 extending from the closed end of the outer tube 161 toward the atomizing seat 21 . The connecting piece 16 also includes an inner tube 163, the inner tube 163 passes through the closed end of the outer tube 161, the inner surface of the inner tube 163 forms part of the airflow channel, the upper tube 26 is inserted into one end of the inner tube 163, and the lower tube 27 is inserted into the inner tube 163. the other end of the inner tube 163 . The closed end of the outer tube 161 also has a liquid through hole 164 and a liquid through hole 165 , both of which are located between the outer surface of the inner tube 163 and the inner surface of the outer tube 162 . The sealing member 17 includes an outer tube 171, an inner tube 172, and an extension extending from the outer surface of the inner tube 172 to the inner surface of the outer tube 171. One end of the extension is recessed to form a receiving space 173, and the other end of the extension has a protruding Sealing portion 174 . The seal 17 also includes a liquid through hole 175 through the extension

During assembly, the liquid outlets of the oil tank housing 14 and the oil tank housing 15 are accommodated between the inner surface of the outer tube 161 and the outer surface of the inner tube 163, and the upper open end of the oil tank housing 18 abuts on the stepped surface 1611 on. The sealing member 17 is also provided between the inner surface of the outer tube 161 and the outer surface of the inner tube 163, and the inner tube 163 is inserted into the inner tube 172, so that the sealing member 17 has an impact on the oil tank housing 14 and the oil tank housing 15. The gap between the liquid outlet and the connecting piece 16 is sealed. The liquid outlet of the oil tank shell 14 is aligned with the liquid through hole 175 and the liquid through hole 165 and is in fluid communication; the liquid outlet of the oil tank shell 15 is aligned with the sealing part 174 and the liquid through hole 164, and the sealing part 174 is open to the liquid. The hole 164 is sealed.

After assembly, the first liquid stored in the first storage unit flows into the buffer unit through the liquid outlet, the liquid through hole 175, and the liquid through hole 165 of the oil tank housing 14, and then flows into the mist through the liquid inlet of the lower pipe 27. The chemical unit 20 is formed, thereby forming a first liquid transfer channel. The second liquid stored in the second storage unit cannot flow into the liquid through hole 164 due to the sealing portion 174 sealing the liquid through hole 164 , and thus cannot flow into the buffer unit and the atomizing unit 20 .

After assembly, the airflow channel, the sealing member 17, the connecting member 16 and the oil tank housing 18 are all fixed, and the difference is that the suction nozzle 11, the first storage unit and the second storage unit can all surround the electronic mist at the same time It rotates in the longitudinal direction (direction indicated by the broken line arrow A in the figure) of the chemicalizer 10 . Specifically, the liquid outlet of the oil tank housing 14 and the oil tank housing 15 can move along the circumferential direction of the annular surface of the receiving space 173. In actual operation, the user can hold the suction nozzle 11 and rotate it counterclockwise or clockwise by 180°, Therefore, the liquid outlet of the oil tank housing 15 is aligned with the liquid through hole 175 and the liquid through hole 165 and is in fluid communication; the liquid outlet of the oil tank housing 14 is aligned with the sealing part 174 and the liquid through hole 164, and the sealing part 174 is opposite to the liquid through hole 164. The liquid through hole 164 is sealed. After the operation, the second liquid stored in the second storage unit flows into the oil tank housing 18 through the liquid outlet, the liquid through hole 175 , and the liquid through hole 165 of the oil tank housing 15 , and then passes through the liquid inlet of the lower pipe 27 The port flows into the atomizing unit 20, thereby forming a second liquid transfer channel. The first liquid stored in the first storage unit cannot flow into the liquid through hole 164 due to the sealing portion 174 sealing the liquid through hole 164 , and thus cannot flow into the oil tank housing 18 and the atomizing unit 20 . Hold the suction nozzle 11 again and rotate it 180° counterclockwise or clockwise to return to the initial state.

Further, a visual window 121 and a visual window 122 can be provided on the casing 12 , the first liquid storage amount stored in the oil tank housing 14 can be observed through the visual window 121 , and the oil can be observed through the visual window 122 The amount of liquid storage buffered in the cartridge housing 18. After the first liquid stored in the first storage unit is used up, hold the suction nozzle 11 and rotate 180° counterclockwise or clockwise to open the second liquid transfer channel, and then use the second liquid stored in the second storage unit. In this way, by sequentially opening the first liquid transfer channel and the second liquid transfer channel, the first liquid transfer channel and the second liquid transfer channel do not simultaneously transfer the first liquid and the second liquid to the atomizing unit, and the stored liquid in the second storage unit Before the second liquid is not used, it is always in a sealed state, and will not come into contact with the air, and will not deteriorate or taste bad.

It can be known from the above description that the first liquid transmission channel and the second liquid transmission channel are partially shared, that is, they both share the liquid through hole 175 , the liquid through hole 165 , the buffer unit and the liquid inlet of the lower pipe 27 . However, both the first liquid and the second liquid flow into the common liquid transfer channel through different liquid outlets, the first liquid stored in the first storage unit will not be transferred to the second storage unit, and the liquid stored in the second storage unit will not be transferred to the second storage unit. The second liquid is also not transferred to the first storage unit, ie the first storage unit and the second storage unit are independent of each other. In this way, when the first liquid and the second liquid are liquids with different tastes, there will be no cross-flavor phenomenon between the two; if one of the liquids is stale and deteriorated, the other liquid will not be contaminated. In other examples, it is also possible to not set the cache unit. In other examples, it is also feasible that the first liquid transfer channel and the second liquid transfer channel do not have a common liquid transfer channel, that is, the first liquid transfer channel and the second liquid transfer channel are independent of each other, and the first liquid does not pass through the second liquid transfer channel. The liquid transfer channel transfers and the second liquid does not transfer through the first liquid transfer channel. In this way, the storage unit and the atomizing unit are in fluid communication with separate liquid transfer channels.

It can be known from the above description that the first storage unit and the second storage unit are active at the same time. In other examples, it is also possible that the first storage unit and the second storage unit are not active at the same time. The first liquid transfer channel is opened or closed by first activating the first storage unit, and then the second liquid transfer channel is opened or closed by activating the second storage unit; at this time, the first liquid transfer channel and the second liquid transfer channel can be Open or close as expected or scheduled. For example, initially, both the first liquid transfer channel and the second liquid transfer channel are in a closed state; first, the first liquid transfer channel is opened by the active first storage unit (the second liquid transfer channel is in a closed state); when the first liquid is used After completion, the second liquid transfer channel is opened by the movable second storage unit (the first liquid transfer channel may or may not be closed). It is conceivable that the situation in which the first liquid transfer channel and the second liquid transfer channel are opened or closed in an expected or predetermined manner is not limited to those listed above, as long as the first liquid transfer channel and the second liquid transfer channel do not transmit at the same time. The first liquid and the second liquid can be sent to the atomization unit.

It can be known from the above description that the first storage unit and the second storage unit are activated at the same time to realize the opening or closing of the first liquid transfer channel and the second liquid transfer channel. In other examples, it is also feasible that at least part of the first liquid transfer channel and at least part of the second liquid transfer channel are configured to be active simultaneously to open or close the liquid transfer channel. Taking the structure shown in FIG. 2 as an example, through a reasonable structural design, the movable connector 16 can open or close the liquid transmission channel.

It can be known from the above description that the first storage unit and the second storage unit are activated at the same time to realize the opening or closing of the first liquid transfer channel and the second liquid transfer channel. In other examples, a switch component may be provided in the first liquid transfer channel and the second liquid transfer channel to realize opening or closing of the first liquid transfer channel and the second liquid transfer channel. For example, a movable part is arranged between the connecting piece 16 and the oil tank housing 18, and the casing 12 has an operation part, through which the movement of the movable part can be controlled, thereby realizing the opening or closing of the liquid transmission channel. It is easy to imagine that it is also feasible to realize the opening or closing of the first liquid transmission channel and the second liquid transmission channel respectively by arranging two movable parts.

It can be known from the above description that when the first storage unit and the second storage unit are active at the same time, one of the first liquid transmission channel and the second liquid transmission channel is open and the other is closed. In other examples, the first liquid transfer channel and the second liquid transfer channel are configured to be closed simultaneously. For example: initially, the first liquid transfer channel and the second liquid transfer channel are both closed; when the first liquid in the first storage unit needs to be used, the first storage unit and the second storage unit are active at the same time, and the first storage unit is opened. The liquid transfer channel, at this time, the second liquid transfer channel is still in a closed state; after the first liquid in the first storage unit is used up, the first storage unit and the second storage unit are activated at the same time to open the second liquid transfer channel, The first liquid transfer channel is closed; after the first storage unit and the second storage unit are simultaneously activated again, both the first liquid transfer channel and the second liquid transfer channel are closed.

It can be known from the above description that the common liquid transfer channel is in a normally open state, and the first liquid transfer channel is also in an open state. The active stroke of the first storage unit has a position to open the first liquid transfer channel (eg, a second counterclockwise or 180° clockwise rotation), and a position to close the first liquid transfer channel (eg, the first counterclockwise or 180° rotation). 180° clockwise rotation); the active stroke of the second storage unit has a position to open the second liquid transfer channel (eg, a first counterclockwise or 180° clockwise rotation), and a position to close the second liquid transfer channel (eg , the second counterclockwise or clockwise 180°). In other examples, it is also possible that the first liquid transfer channel is in a normally open state. At this time, the opening or closing of the second liquid transfer channel can be realized by only activating the second storage unit.

It can be known from the above description that the first storage unit and the second storage unit are active at the same time. In other examples, the first storage unit and the second storage unit are inactive, and it is also feasible to pass the active buffer unit; or, the active atomization unit 20 is also feasible.

The battery 22 provides power to the electronic atomizer 10 . The battery 22 can be a disposable battery, and the capacity design of the battery 22 needs to be sufficient to support the heating and atomization of the first liquid and the second liquid. In other examples, the battery 22 may also be a rechargeable battery.

The fixing member 23 is fixed on the base 25 , and the fixing member 23 is used for fixing the airflow sensor 24 . Referring again to FIG. 1 , the base 25 has an air intake hole 251 , through which the air flows into and flows through the air flow sensor 24 . The air flow sensor 24 can sense and feed back a sensing signal to the circuit board (not shown). , and then control the atomizing unit 20 to start heating.

1 to 7 are all described by taking two storage units as an example, and it is also mentioned in the foregoing text that it is also feasible to provide more than two storage units. For better understanding, the following description is given in conjunction with Figure 8:

As shown in FIG. 8 , the electronic atomization device 10 includes four storage units a, b, c, and d, and the four storage units are all arranged around the airflow channel f. For the specific structures of the storage unit and the airflow channel, reference may be made to the foregoing content. In this example, the four storage units are all independent of each other, and each storage unit can be in fluid communication with the atomization unit through at least one liquid transfer channel. For ease of description, each storage unit is in fluid communication with the atomizing unit through a liquid transfer channel, denoted as a1, b1, c1, d1, respectively. Similar to the foregoing, the 4 liquid delivery channels do not simultaneously deliver liquid to the atomizing unit and can be opened or closed at a desired or predetermined time. For example: open in sequence a1, b1, c1, d1; or, first open a1, then b1, and then open c1 and d1 at the same time; or, first open a1 and b1 at the same time, then open c1 and d1 at the same time; or, Open a1 first, then open b1, c1, and d1 at the same time.
