The atomization process of the atomizer is generally as follows: atomized liquid flows into the liquid guide body from the liquid storage cavity, the liquid guide body conducts the atomized liquid to a region connected with the heating body, under the heating effect of the heating body, the atomized liquid around the heating body is vaporized to form aerosol which can be sucked by a user, when the user sucks, suction airflow is formed on an airflow circulation path of the airflow channel, the aerosol is taken away when the suction airflow flows through the heating body, and finally the aerosol flows out to an oral cavity of the user along with the suction airflow from an air outlet of the airflow channel to be sucked by the user.

Wherein, in the in-process that the atomizer carried out the atomizing work, the atomizing core can consume the atomizing liquid in the stock solution chamber for the internal pressure in stock solution chamber reduces and forms certain negative pressure (i.e. the internal air pressure in stock solution chamber is less than external atmospheric pressure this moment), this negative pressure can make the subsequent resistance that leads the atomizing core of atomizing liquid increase, consequently in order to make the subsequent atomizing liquid to lead the atomizing core smoothly, guarantee that the user can continue normal suction, need carry out the return air to the stock solution intracavity, in the return air in-process, external air that is arranged in the air current passageway can see through the atomizing core and get back to the stock solution intracavity, in order to promote the atmospheric pressure in the stock solution chamber, reduce the atmospheric pressure differential between stock solution chamber and the external environment (reduce the negative pressure in the stock solution storehouse promptly), when the atmospheric pressure in the stock solution chamber reaches equilibrium with external atmospheric pressure, the atomizing liquid in the stock solution chamber alright normally leads the atomizing core, make the atomizing core can normally carry out the atomizing work.

In the related art, when producing the atomizer, the atomized liquid is usually required to be injected into the liquid storage cavity in advance, however, in the liquid injection process, the atomized liquid is inevitably filled into the liquid storage cavity, so that the air in the liquid storage cavity is almost completely extruded out by the atomized liquid to enable the interior of the liquid storage cavity to approach to a vacuum state due to almost no air, in the process of using the atomizer filled with the atomized liquid for atomizing operation, when the atomized liquid needs to be supplemented due to the fact that the atomized liquid is consumed by the atomized core, the space which can almost contain the air due to the fact that the liquid storage cavity is filled with the tobacco tar is not filled, so that the atomizer cannot normally perform air return, namely, the external air is difficult to enter into the liquid storage cavity, the air pressure in the liquid storage cavity is always in a state smaller than the external air pressure (namely, always in a negative pressure state), and then the atomized liquid in the liquid storage cavity cannot be normally led into the atomized core, namely, the atomized core is difficult to acquire the atomized liquid from the cavity to supplement, and accordingly the phenomenon that the atomized liquid is dry and burns out can be caused, and the atomized core cannot be sucked by a user, even, and the user can feel bad.

In the technical scheme of the embodiment, based on the above structural design, through add the first cavity 101 that separates the setting with the second cavity 102 in the inside of atomizer (specifically, set up through baffle 2 mutual separation between first cavity 101 and the second cavity 102), and set up the anti-liquid ventilative structure 3 that is used for intercommunication first cavity 101 and second cavity 102 between first cavity 101 and second cavity 102, in the anti-liquid ventilative effect of anti-liquid ventilative structure 3 (i.e. anti-liquid ventilative structure 3 can allow gas to pass through, but not allow liquid to pass through), make can realize gas exchange through anti-liquid ventilative structure 3 between first cavity 101 and the second cavity 102 (i.e. the air in the second cavity 102 can enter into in the first cavity 101, the air in the first cavity 101 also can enter into in the second cavity 102), nevertheless, atomized liquid in the second cavity 102 can not enter into in the first cavity 101, so, even if second cavity 102 has annotated the atomized liquid, because of the existence of first cavity 101, the second cavity 102 can not be in the state in the true sense, can make the second cavity 102 can be in the normal sense and can make the air pressure of the second cavity 102 can enter into the normal air-phase after the second cavity 102, can make the normal air pressure of the air-phase normal, and the air-permeable structure can be carried out to the second cavity 101, and the air can reach the normal air pressure of the air-phase, and the air-permeable condition can be carried out in the second cavity 101, and the air-phase normal condition can be carried out, and the air-phase can be further, and the air-free to the air-phase can be carried out the air phase normal air condition, and the air storage can be carried out the air phase cavity 4.

Further, referring to fig. 2-3 and fig. 6, in some alternative embodiments of the present utility model, the liquid-proof and air-permeable structure 3 includes at least one first channel 31 disposed through the partition board 2, and the inner diameter of the first channel 31 is 0.05mm to 0.5mm, and for example, as shown in fig. 3, assuming that the inner diameter of the first channel 31 is D1, 0.05mm is equal to or less than D1 is equal to or less than 0.5mm.

In this embodiment, based on the above structural design, at least one first channel 31 for communicating the first cavity 101 and the second cavity 102 is formed on the partition board 2, and the inner diameter of the first channel 31 is reasonably designed to be 0.05-0.5 mm, so that the first channel 31 can be regarded as a capillary channel, before the atomized liquid is injected into the second cavity 102 in the process of producing the atomizer, after the air in the second cavity 102 enters the first channel 31, capillary air resistance can be formed in the first channel 31, and under the common blocking effect of the capillary air resistance and the internal air pressure of the first cavity 101, the atomized liquid in the second cavity 102 is difficult to flow into the first cavity 101 through the first channel 31 in the process of producing the atomizer or in the process of using the atomizer, and in addition, the first channel 31, which can be regarded as a capillary channel, can ensure that gas exchange can be realized between the first cavity 101 and the second cavity 102, namely, the air in the second cavity 102 can also enter the first cavity 101 through the first channel 31 into the first cavity 101. Therefore, the first channel 31 with the inner diameter of 0.05-0.5 mm provided by the embodiment can play a role in preventing liquid from ventilation, so even if the second cavity 102 is filled with atomized liquid, the second cavity 102 is not in a truly vacuum state due to the existence of the first cavity 101, so that in the process of atomizing operation of a subsequent atomizer, external air can enter the first cavity 101 through the first channel 31 for storage after entering the second cavity 102, the air pressure of the first cavity 101 can reach a state balanced with the external air pressure, and atomized liquid in the second cavity 102 can be normally led into the atomized core 4 for replenishment, and the problem of liquid shortage and dry combustion of the atomized core 4 can be effectively avoided.

Further, referring to fig. 2-3 and fig. 6, in some alternative embodiments of the present utility model, the first channels 31 are provided in a plurality, and each first channel 31 has an inner diameter of 0.1mm to 0.5mm.

In this embodiment, by providing the partition plate 2 with the plurality of first channels 31 that can be regarded as capillary channels, the air return speed of the atomizer is advantageously increased, so that the internal air pressure of the first cavity 101 can reach a state balanced with the outside more quickly, and further, the atomized liquid in the second cavity 102 can be introduced into the atomized core 4 more quickly to be replenished, and in a specific implementation, optionally, the plurality of first channels 31 are uniformly spaced along the circumferential direction of the partition plate 2, and as illustrated in fig. 6 and 8, the first channels 31 are exemplarily provided with four first channels 31 that are uniformly spaced along the circumferential direction of the partition plate 2. In addition, in the range of 0.05-0.5 mm in inner diameter, the inner diameter of the first channel 31 is further reasonably adjusted to 0.1-0.5 mm, so that the ventilation effect of the first channel 31 can be improved and the processing difficulty of the first channel 31 can be reduced while the ventilation effect of the first channel 31 can be ensured.

Further, referring to FIGS. 2-3, in some alternative embodiments of the present utility model, the length of the first channel 31 is 0.8 mm-30 mm, and as shown in FIG. 3, assuming that the length of the first channel 31 is L1, there is 0.8 mm.ltoreq.L1.ltoreq.30mm. By the arrangement, after air enters the first channel 31, capillary air resistance is more easily formed in the first channel 31, so that the liquid prevention effect of the first channel 31 is improved. More preferably, the length of the first channel 31 is preferably 1 mm-10 mm, so that the processing difficulty of the first channel 31 and the liquid-proof ventilation effect of the first channel 31 can be well considered, that is, the processing difficulty of the first channel 31 is reduced, and the first channel 31 can obtain a better liquid-proof ventilation effect. In this example, it will be appreciated that in some embodiments, the length of the first channel 31 may be considered as the thickness of the separator 2.

Further, referring to fig. 4-5, in alternative embodiments of the present utility model, the liquid-proof and air-permeable structure 3 includes at least one second channel 32 disposed through the partition board 2 and a liquid-proof and air-permeable membrane 33 disposed in a one-to-one correspondence with the second channel 32, where the inner diameter of the second channel 32 is greater than 0.5mm and less than 30mm, and as illustrated in fig. 5, assuming that the inner diameter of the second channel 32 is D2, 0.5mm < D2 < 30mm, and optionally, the inner diameter of the second channel 32 may be further set to 1 mm-10 mm.

In the present embodiment, in the specific implementation, the liquid-proof gas-permeable membrane 33 may be disposed at any position on the flow path of the second channel 32, for example, may be disposed inside the second channel 32, or may be disposed so as to cover the port of the second channel 32, so long as it is possible to make it difficult for the atomized liquid in the second cavity 102 to completely flow into the first cavity 101 through the second channel 32. Preferably, the liquid-proof gas-permeable membrane 33 is disposed to cover the port of the second channel 32, so that the difficulty in disposing the liquid-proof gas-permeable membrane 33 is reduced compared to disposing the liquid-proof gas-permeable membrane 33 inside the second channel 32, and as shown in fig. 5, the liquid-proof gas-permeable membrane 33 is disposed to cover the upper port of the second channel 32. In particular, the liquid-proof breathable film 33 may be a polyethylene waterproof breathable film or a polytetrafluoroethylene waterproof breathable film, as long as the liquid-proof breathable effect can be achieved, and this embodiment is not particularly limited.

In this embodiment, based on the above structural design, at least one second channel 32 for communicating the first cavity 101 and the second cavity 102 is formed on the partition board 2, and the liquid-proof air-permeable membrane 33 is disposed on the flow path of each second channel 32, so that, in the process of producing the atomizer, the atomized liquid in the second cavity 102 is difficult to flow into the first cavity 101 completely through the second channel 32 under the liquid-proof action of the liquid-proof air-permeable membrane 33, and air exchange between the first cavity 101 and the second cavity 102 can be ensured under the air-permeable action of the liquid-proof air-permeable membrane 33, that is, air in the second cavity 102 can pass through the second channel 32 and the liquid-proof air-permeable membrane 33 and enter into the first cavity 101, and air in the first cavity 101 can also pass through the second channel 32 and the liquid-proof air-permeable membrane 33 and enter into the second cavity 102. Therefore, the liquid-proof ventilation structure 3 including the second channel 32 and the liquid-proof ventilation film 33 provided in this embodiment can play the same role in liquid-proof ventilation, so, even if the second cavity 102 is filled with atomized liquid, the second cavity 102 is not in a truly vacuum state due to the existence of the first cavity 101, so that in the process of atomizing operation of the subsequent atomizer, external air can enter the first cavity 101 for storage through the second channel 32 and the liquid-proof ventilation film 33 after entering the second cavity 102, so that the air pressure of the first cavity 101 can reach the state balanced with the external air pressure, and atomized liquid in the second cavity 102 can be normally led into the atomized core 4 for replenishment, thereby effectively avoiding the problem of liquid-lack dry combustion of the atomized core 4.

In the present embodiment, it is understood that since the inner diameter of the second passage 32 is larger than 0.5mm and smaller than 30mm, if the liquid-proof air-permeable membrane 33 is not provided on the flow path of the second passage 32, both the air and the atomized liquid in the second cavity 102 can enter the first cavity 101 through the second passage 32.

Further, referring to fig. 9-10, in still other alternative embodiments of the present utility model, the liquid-proof ventilation structure 3 includes a ventilation gap 344, the ventilation gap 34 is disposed between the outer peripheral wall of the partition 2 and the inner peripheral wall of the accommodating cavity 100 and/or between the inner peripheral wall of the partition 2 and the inner peripheral wall of the accommodating cavity 100, and the size of the ventilation gap 34 is 0.05mm to 0.5mm, for example, as shown in fig. 10, assuming that the size of the ventilation gap 34 is L2, the size of L2 is 0.05 mm.ltoreq.l2.ltoreq.0.5 mm.

In this embodiment, based on the above structural design, by providing the ventilation gap 34 between the outer peripheral wall of the partition board 2 and the inner peripheral wall of the accommodating cavity 100, and/or by providing the ventilation gap 34 between the inner peripheral wall of the partition board 2 and the inner peripheral wall of the accommodating cavity 100, and reasonably designing the gap size of the ventilation gap 34 to be 0.05-0.5 mm, the ventilation gap 34 can be regarded as a capillary channel, during the process of producing the atomizer, after the air in the second cavity 102 enters the ventilation gap 34 before the atomized liquid is injected into the second cavity 102, capillary air resistance can be formed in the ventilation gap 34, and under the combined blocking effect of the capillary air resistance and the internal air pressure of the first cavity 101, the atomized liquid in the second cavity 102 is difficult to flow into the first cavity 101 through the ventilation gap 34, or during the process of using the atomizer, and the ventilation gap 34 can be regarded as the capillary channel, and the air between the first cavity 101 and the second cavity 102 can be exchanged through the ventilation gap 34 into the second cavity 101. Therefore, the ventilation gap 34 with the gap size of 0.05-0.5 mm provided by the embodiment can play a role in preventing liquid from ventilation, so even if the second cavity 102 is filled with atomized liquid, the second cavity 102 is not in a truly vacuum state due to the existence of the first cavity 101, so that in the process of atomizing operation of a subsequent atomizer, external air can enter the first cavity 101 through the ventilation gap 34 for storage after entering the second cavity 102, the air pressure of the first cavity 101 can reach a state balanced with the external air pressure, and atomized liquid in the second cavity 102 can be normally led into the atomized core 4 for replenishment, and the problem of liquid shortage and dry burning of the atomized core 4 can be effectively avoided.
