The present application will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 4, fig. 1 is a disassembled schematic view of an atomizer 1 according to an embodiment of the present disclosure; FIG. 2 provides a disassembled schematic view of an atomizer 1 according to another embodiment of the present application;

FIG. 3 is a sectional view taken along line A-A of FIG. 1; FIG. 4 is a sectional view taken along line B-B of FIG. 1; in the present embodiment, an atomiser 1 is provided, the atomiser 1 being for heating and atomising an aerosol-generating substrate to form an aerosol for inhalation by a user when energised. The aerosol-generating substrate may be a liquid medicament formed by dispersing a drug in a liquid solvent, an oil with an added fragrance, or any other liquid suitable for electronic atomization.

As shown in fig. 1 to 4, the atomizer 1 includes a first housing 11, a base 12, a holder 13, and an atomizing core 14. Wherein the first housing 11 is formed with a mouthpiece 111, an air passage 112 communicating with the mouthpiece 111, a reservoir cavity 113 for storing an aerosol-generating substrate, and a first fool-proof structure 114 (see fig. 6) arranged outside a side wall of the first housing 11. At least part of the base 12 is disposed in the first housing 11, and a liquid storage structure is disposed outside a side wall of the base 12 for storing aerosol condensate. In one embodiment, the reservoir structure is a reservoir disposed outside of the sidewall of the base 12. The liquid storage component can be liquid absorption cotton; such as sponge, cotton, etc.

The holder 13 is provided in the first housing 11, and as shown in fig. 4, the holder 13 includes an insertion portion 131 and a cover portion 132 connected to each other. The embedded portion 131 of the bracket 13 is inserted into the base 12 and cooperates with the base 12 to form an atomization cavity, and the atomization cavity is located inside the sidewall of the base 12 and is isolated from the liquid storage structure, i.e., the atomization cavity is spaced from the liquid storage structure. Further, at least a portion of the sidewall of the embedding portion 131 is spaced from the sidewall of the base 12 to define a first air outlet channel 1311, the first air outlet channel 1311 is communicated with the air duct 112, and the aerosol atomized in the atomizing chamber flows out to the air duct 112 through the first air outlet channel 1311. Further, the first air outlet channel 1311 is also communicated with the liquid storage structure; therefore, after the user sucks the aerosol every time, the aerosol remained in the air passage 112, the first air outlet channel 1311 and the atomizing cavity is easy to flow to the liquid storage structure for storage, and the probability of the aerosol condensate leakage problem is effectively reduced. Specifically, the number of the first air outlet channels 1311 and the liquid storage structures can be two, and the two first air outlet channels 1311 and the two liquid storage structures are arranged in a one-to-one correspondence manner along the radial direction of the base 12, so that the condensate formed after condensation of the aerosol flowing out of the first air outlet channels 1311 can be stored in the liquid storage structures as far as possible, and the risk of liquid leakage is reduced.

Referring to fig. 4, the cover 132 is located outside the base 12 and abuts against the end of the side wall of the base 12 facing the cover 132; and a gap 1321 is formed at the position where the cover 132 abuts against the side wall of the base 12, and the gap 1321 communicates with the first air outlet channel 1311 and the liquid storage structure. In one embodiment, the cover 132 further has a flow guiding wall disposed on at least one side of the gap 1321, and the flow guiding wall extends from the first air outlet channel 1311 to the liquid storage structure for guiding the condensate to the liquid storage structure. Specifically, the end of the sidewall of the base 12 abuts against the drainage wall, the drainage wall is provided with a liquid guiding surface, and the liquid guiding surface is connected to the wall surface of the first gas outlet channel 1311 so as to guide the condensate on the wall surface of the first gas outlet channel 1311 to the outside of the sidewall of the base 12. Of course, in other embodiments, the gap 1321 can be formed by the end of the side wall of the base 12 being recessed toward the direction away from the cover 132; or, a first arc-shaped groove is formed by the end of the side wall of the base 12 being recessed towards the direction away from the cover 132, a second arc-shaped groove is formed by the position of the cover 132 abutting against the end of the side wall of the base 12 being recessed towards the direction away from the base 12, and the notch 1321 is formed by the cooperation of the first arc-shaped groove and the second arc-shaped groove.

The gap 1321 is arranged at the connection position of the cover 132 and the embedded part 131, so that the manufacturing is easy, and after the user stops sucking, the residual aerosol can quickly flow out from the gap 1321 and form condensate to be stored in the liquid storage structure, and the probability that the residual aerosol overflows from other gaps of the base 12 or the bracket 13 to form condensate, so that the leakage problem is caused is effectively reduced.

Specifically, in conjunction with fig. 1 and 4, the cover 132 is further formed with a second air outlet passage 1327, a third air outlet passage 1328, and an air outlet 1322. Wherein, the second air outlet channel 1327 extends along the transverse direction of the cover 132, a first end of the second air outlet channel 1327 is communicated with the first air outlet channel 1311, and a second end of the second air outlet channel 1327 is communicated with the third air outlet channel 1328; the third air outlet passage 1328 extends in the longitudinal direction S perpendicular to the circumferential direction of the base 12 and communicates with the air outlet 1322; first outlet gas channel 1311, second outlet gas channel 1327, and third outlet gas channel 1328 form an outlet gas channel of atomizer 1. The air outlet 1322 is located at an end of the cover portion 132 away from the insert portion 131, and is communicated with the air passage 112, and aerosol formed by atomization in the atomization chamber flows out through the atomization chamber, the air outlet channel, the air outlet 1322, the air passage 112, and the suction nozzle 111 in sequence. Wherein, through setting up the second air outlet channel 1327 and the third air outlet channel 1328 that extend, can prolong the route that the aerosol reaches suction nozzle 111 to can reduce the temperature of aerosol to a certain extent, in order to avoid taking place the problem that the mouth was scalded in the suction.

As shown in fig. 4, an atomizing wick 14 is located within insert 131 and between two first air outlet channels 1311 for heating and atomizing an aerosol-generating substrate when energized to form an aerosol for inhalation by a user. First air outlet channel 1311 is specifically located between atomizing wick 14 and the reservoir structure. The specific structure and function of the atomizing core 14 are the same as or similar to those of the atomizing core in the conventional atomizer, and the same or similar technical effects can be achieved. It will be understood that the structure of the atomizing core is not particularly limited as long as it is capable of atomizing the aerosol-generating substrate.

In another embodiment, as shown in fig. 1 and 4, the liquid storage structure is a liquid storage tank 121 disposed outside the side wall of the base 12, and a notch of the liquid storage tank 121 is disposed toward the air outlet 1322 along a longitudinal direction S perpendicular to the circumferential direction of the base 12; and the reservoir 121 is communicated with the first air outlet channel 1311 through the gap 1321 on the cover 132. So, vertical the placing at atomizer 1, and suction nozzle 111 when up, only at the full whole reservoir 121 of condensate collection, the condensate just can be gone out from the notch overflow of reservoir 121, and storage space is great, and the album liquid volume is more. However, it is understood that if the notch of the reservoir 121 is provided toward the inner wall surface of the first housing 11, the condensate may overflow as long as the condensate floods the bottom wall of the reservoir 121 (i.e., the reservoir 121 is away from the side wall of the lid portion 132 in the longitudinal direction S perpendicular to the circumferential direction of the base 12), and the amount of the condensate stored is small. Therefore, compare in the scheme that sets up the opening of reservoir 121 towards the internal wall face of first casing 11, the scheme that this embodiment provided, aerosol condensate is stored to reservoir 121 in easily, is difficult to leak out, greatly reduced the probability of condensate emergence weeping problem.

In addition, the top wall is not arranged on one side of the liquid storage tank 121 facing the air outlet 1322, that is, an open notch is directly formed, compared with the top wall arranged on one side of the liquid storage tank 121 facing the air outlet 1322, and a through hole is formed in the top wall so that aerosol condensate flowing out of the notch 1321 can flow in.

Of course, in other embodiments, the side of the sump 121 facing the air outlet 1322 along the longitudinal direction S perpendicular to the circumferential direction of the base 12 may also be provided with a top wall, i.e., without a notch, to form a closed cavity. This can avoid the problem of the condensate stored in the reservoir 121 leaking out of the notch when the atomizer 1 is placed obliquely to some extent. In this embodiment, the common sidewall 122 may be directly perforated to communicate the reservoir 121 and the first gas outlet channel 1311; an opening may also be formed in the top wall of the reservoir 121 at a position corresponding to the notch 1321 to communicate the reservoir 121 with the first air outlet passage 1311.

Specifically, as shown in fig. 4, a portion of the sidewall of the base 12 is a common sidewall 122, and the common sidewall 122 doubles as a sidewall of the reservoir 121 and the first air outlet channel 1311. In this embodiment, the gap 1321 is opened at a position of the cover 132 abutting against the common sidewall 122 to directly communicate the reservoir 121 and the first air outlet channel 1311. Above-mentioned through making reservoir 121 and first air outlet channel 1311 share a lateral wall, both can save the cost, and compare in reservoir 121 and the scheme that first air outlet channel 1311 set up along the lateral direction interval of base 12, the linear distance of reservoir 121 and first air outlet channel 1311 along the lateral direction of base 12 is shorter, can effectively shorten the route that the aerosol condensate in first air outlet channel 1311 reaches reservoir 121 through breach 1321 like this, with the condensation of reduction remaining aerosol in breach 1321, and then avoid the problem that the breach 1321 was blockked up to the aerosol condensate to take place.

In particular embodiments, in order to further reduce the risk of leakage of the atomiser 1; as shown in fig. 2, a plurality of liquid collecting grooves 123 are further disposed on the outer side of the side wall of the base 12, the notches of the plurality of liquid collecting grooves 123 are disposed facing the first housing 11, and the plurality of liquid collecting grooves 123 are respectively communicated with the liquid storage structure. Like this when the condensate volume in hydrops groove 123 is more, can make the condensate in the hydrops groove 123 flow in to stock solution structure, avoid flowing out the problem that leads to the weeping from the notch of hydrops groove 123. Specifically, the liquid collecting grooves 123 are uniformly distributed on two sides of the liquid storage structure, and the liquid collecting grooves 123 on each side are arranged at intervals along a longitudinal direction S perpendicular to the circumferential direction of the base 12.

As shown in fig. 2, the cover portion 132 of the holder 13 is further provided with a ventilation hole 1324 and a ventilation groove 1323 communicating with the ventilation hole 1324; the ventilating holes 1324 are located on the side of the cover part 132 facing away from the base 12 and communicate with the space on the side of the cover part 132 facing away from the base 12; the ventilation slot 1323 is disposed on the periphery of the cover 132, communicates with the liquid storage cavity 113 through the ventilation hole 1324, and is used for ventilation of the liquid storage cavity 113 to maintain the air pressure balance inside and outside the liquid storage cavity 113, thereby facilitating liquid discharge. The ventilation slot 1323 is further provided with a vent 1325, the ventilation slot 1323 is communicated with the liquid storage structure through the vent 1325, so that when the aerosol generating substrate in the liquid storage cavity 113 leaks into the ventilation slot 1323, the aerosol generating substrate can flow into the liquid storage structure through the vent 1325 to be stored; alternatively, when aerosol condensate is present in the ventilation slot 1323, the condensate can flow into the liquid storage structure through the vent 1325 and be stored, thereby preventing the ventilation slot 1323 from being blocked by the aerosol-generating substrate or the condensate, which may result in the problem of ventilation failure. Meanwhile, the problem that the condensate or the aerosol generating substrate in the ventilation slot 1323 is pushed into the liquid storage cavity 113 by external gas under the action of pressure difference to influence the aerosol generating substrate in the liquid storage cavity 113, so that the aerosol generating substrate is deteriorated and the smoking taste of the aerosol is influenced can be prevented.

Specifically, as shown in fig. 2, along a longitudinal direction S perpendicular to the circumferential direction of the base 12, the height of the position of the air vent 1323 is higher than the height of the position of the liquid storage structure; this facilitates direct flow of aerosol-generating substrate and/or aerosol condensate within the aeration tank 1323 into the liquid storage structure under the influence of gravity. Further, the vent 1325 is also higher than the liquid storage structure; in this way, the vent 1325 is less likely to be blocked by aerosol-generating substrate and/or aerosol condensate, which leaks within the venting slot 1323, and more likely to flow into the reservoir structure.

Specifically, the transverse cross-sectional area of the ventilation slot 1323 gradually increases along the airflow direction of the ventilation slot 1323; or the transverse cross-sectional area of the portion of the purge slot 1323 near the reservoir 113 is larger than the transverse cross-sectional area of the portion of the purge slot 1323 away from the reservoir 113. The ventilation slot 1323 is thus less likely to be blocked by leaking aerosol-generating substrate or condensate, resulting in better ventilation.

In one embodiment, as shown in fig. 2, the ventilation slot 1323 includes at least one first groove 132a and at least one second groove 132b extending along the circumferential direction of the cover 132, the first groove 132a and the second groove 132b are respectively recessed toward the central position of the cover 132, the first groove 132a is communicated with the ventilation hole 1324, and the at least one second groove 132b is respectively communicated with the first groove 132a and the liquid storage structure and is located between the at least one first groove 132a and the liquid storage structure along the longitudinal direction S perpendicular to the circumferential direction of the base 12; and the lateral cross-sectional area of the first groove 132a is greater than the lateral cross-sectional area of the second groove 132 b; this prevents the first recess 132a from being blocked, which may affect the ventilation effect of the ventilation slot 1323. Wherein, the area range of the first groove 132a along the direction of the bracket 13 departing from the base 12 can be more than 0.6 mm.

Specifically, as shown in fig. 2, the adjacent two first grooves 132a, the adjacent two second grooves 132b, and the adjacent two first grooves 132a and second grooves 132b communicate with each other through the communication hole 1326. The two adjacent communication holes 1326 and the air ports 1325 may be arranged in a staggered manner in the longitudinal direction S perpendicular to the circumferential direction of the base 12.

Of course, in other embodiments, as shown in FIG. 5, each communication hole 1326 may be aligned with the vent 1325 along a longitudinal direction S perpendicular to the circumferential direction of the base 12; therefore, the condensed liquid in the first groove 132a can smoothly flow to the second groove 132b and flow to the liquid storage tank 121 for storage through the vent 1325, and the condensed liquid or the aerosol-generating substrate in the first groove 132a and/or the second groove 132b is prevented from blocking the air vent 1323 or being pushed into the liquid storage cavity 113 by external air to influence the aerosol-generating substrate in the liquid storage cavity 113, so that the aerosol-generating substrate is prevented from deteriorating, and the smoking taste of the aerosol is further influenced. It is understood that the aerosol not drawn by the user flows to the reservoir 121, the effusion cell 123 and the air exchange cell 1323 to form condensate, which is stored in the cells, and when the air exchange cell 1323 is filled with the condensate, the air exchange effect of the air exchange cell 1323 is affected; and under the action of the pressure difference, the gas reaches the ventilating hole 1324 in the shortest route, and at the moment, part of the condensate in the ventilating groove 1323 is pushed into the liquid storage cavity 113 by the gas, so that the phenomenon that the gas pushes the condensate to destroy the ventilating effect can be reduced only by making the gas go straight as much as possible.

In the embodiment, please refer to fig. 5, a connecting groove 1231 is disposed on a groove wall of at least one liquid accumulating groove 123 of the plurality of liquid accumulating grooves 123, and the liquid accumulating groove 123 is communicated with the second groove 132b and the first groove 132a through the connecting groove 1231 and the communicating hole 1326; this allows the condensate or leaked aerosol-generating substrate in the first groove 132a and the second groove 132b to further flow out to the effusion cell 123 through the communication hole 1326 and the connection groove 1231 for storage, thereby further preventing the problem of clogging of the ventilation groove 1323 and allowing the ventilation groove 1323 to ventilate more smoothly.

Specifically, along a longitudinal direction S perpendicular to the circumferential direction of the base 12, the plurality of liquid collecting grooves 123 are located below the second air exchanging groove 1323, each groove wall of the plurality of liquid collecting grooves 123 is provided with a connecting groove 1231, and the plurality of connecting grooves 1231 on the same side are aligned along the longitudinal direction S perpendicular to the circumferential direction of the base 12, so that aerosol generating substrates or condensate flowing from the air exchanging grooves 1323 can smoothly flow into the liquid storing structure for storage through a through hole communicating the liquid collecting grooves 123 with the liquid storing structure under the action of gravity; in this way, when the amount of aerosol-generating substrate or condensate flowing from the ventilation slot 1323 is large, the problem of leakage of aerosol-generating substrate or condensate from the effusion slot 123 can be avoided as much as possible.

Of course, in other embodiments, the ventilating slot 1323 may also spirally surround the outer side of the side wall of the cover part 132 along the circumferential direction of the cover part 132, which is not limited in the present application as long as the transverse cross-sectional area of the ventilating slot 1323 gradually increases along the airflow direction of the ventilating slot 1323; or the transverse cross-sectional area of the portion of the venting groove 1323 close to the reservoir 113 may be larger than the transverse cross-sectional area of the portion of the venting groove 1323 far from the reservoir 113.
