The atomizing device 1 includes an atomizer 10 and a power supply assembly 50, and the atomizer 10 is connected to the power supply assembly 50. The power supply assembly 50 is configured to power the atomizer 10, the atomizer 10 being capable of converting electrical energy into thermal energy, thereby atomizing the aerosol-generating substrate within the atomizer 10 to form an atomized gas for inhalation by a user.

Referring to fig. 2 to 3, an atomization space 310 and a buffer space 330 are provided in the atomizer 10. A partition is provided in the atomizer, and may be used to partition the atomizing space 310 from the buffer space 330 and to guide the liquid in the atomizing space 310 into the buffer space 330, thereby helping to avoid the liquid in the atomizing space 310 from leaking out or being sucked by a user.

In some of these embodiments, the nebulizer 10 may further be provided with a reservoir 350, the reservoir 350 may be provided on a side of the nebulization space 310 facing away from the buffer space 330, the reservoir 350 being adapted to receive an aerosol-generating substrate.

In some embodiments, the atomizer 10 may include a housing assembly 300, and the liquid storage chamber 350, the atomizing space 310, and the buffer space 330 may be disposed in the housing assembly 300, and the liquid storage chamber 350, the atomizing space 310, and the buffer space 330 may be sequentially disposed.

Wherein the housing assembly 300 may be generally tubular, cylindrical, or other shape.

The partition member 110 may include a body 113 and a boss 115 that are connected, the atomizing space 310 and the buffer space 330 are respectively located at two opposite sides of the body 113, the boss 115 is convexly disposed in the buffer space 330, the partition member 110 is provided with a liquid guiding hole 111, the liquid guiding hole 111 penetrates through the body 113 and the boss 115 and communicates the atomizing space 310 with the buffer space 330, so that liquid accumulated in the atomizing space 310 can enter the buffer space 330 through the liquid guiding hole 111, and liquid in the atomizing space 310 can be collected in the buffer space 330, thereby helping to avoid liquid in the atomizing space 310 from leaking out or being absorbed by a user. In addition, the atomizer 10 is provided with the boss 115, so that liquid in the buffer space 330 is not easy to enter the atomizing space 310 through the liquid guide hole 111, and liquid in the atomizing space 310 is easy to enter the buffer space 330 through the liquid guide hole 111, thereby being beneficial to reducing the situation that the liquid in the buffer space 330 flows into the atomizing space 310, and further improving the liquid leakage preventing performance of the atomizer 10.

In addition, the atomizer 10 of this application embodiment can be with the leading-in buffer memory space 330 of liquid in the atomizer space 310, need not to use the stock solution cotton, has reduced manufacturing cost, and prevent buffer memory space 330 and compare the stock solution cotton can hold more liquid, the difficult entering atomizer space 310 of liquid in the buffer memory space 330 has promoted the leak protection performance of atomizer 10, also can avoid the weeping to be atomized and influence the quality of the aerosol that the atomizing formed.

Specifically, by providing the boss 115, since the boss 115 has a certain distance with respect to the body 113, when the atomizer 10 is placed, the liquid in the buffer space 330 can accumulate between the outer surface of the boss 115 and the inner wall of the buffer space 330, so that the liquid is difficult to enter the atomizer space 330 through the liquid guide hole 111, thereby improving the liquid leakage preventing performance of the atomizer 10.

In some of these embodiments, the divider 110 may be coupled within the housing assembly 300, for example, the divider 110 may be integrally formed with the housing assembly 300, or the divider 110 may be coupled within the housing assembly 300 as a separate structure.

In some embodiments, the longer the boss 115 protrudes in the buffer space 330, the more difficult the liquid in the buffer space 330 is to enter the atomizing space 310 through the liquid guiding hole 111 when the atomizer 10 is inverted, so that the atomizer 10 can better block the liquid in the buffer space 330 from flowing to the atomizing space 310 by arranging the boss 115, and further improve the liquid leakage preventing performance of the atomizer 10.

In some embodiments, the liquid guiding hole 111 has a liquid inlet 1111 and a liquid outlet 1113, the liquid inlet 1111 is communicated with the atomizing space 310, the liquid outlet 1113 is communicated with the buffer space 330, the area of the liquid inlet 1111 is larger than that of the liquid outlet 1113, so that the liquid in the atomizing space 310 can more smoothly enter the liquid guiding hole 111 through the liquid inlet 1111 and then enter the buffer space 330 through the liquid outlet 1113, and the liquid in the buffer space 330 is not easy to enter the liquid guiding hole 111 through the liquid outlet 1113, thereby improving the liquid leakage preventing performance of the atomizer 10, improving the liquid leakage condition of the atomizer 10 and improving the use feeling of a user.

In some embodiments, the liquid generates capillary resistance at the liquid outlet 1113, for example, the liquid outlet 1113 may be a capillary, and the liquid may form a film structure at the liquid outlet 1113 due to the surface tension of the liquid, so that the film structure may block the flow of the liquid, and thus the situation that the liquid in the buffer space 330 enters the atomizing space 310 through the liquid guiding hole 111 may be further reduced, and the leak-proof performance of the atomizer 10 is improved. The liquid in the atomization space 310 can flow to the liquid guide hole 111, and when the liquid in the liquid guide hole 111 is more, the gravity of the liquid can overcome the capillary resistance of the liquid at the liquid outlet 1113, so that the liquid in the atomization space 310 can enter the buffer space 330 through the liquid guide hole 111.

Wherein the body 113 may be coupled to the housing assembly 300. The body 113 may be integrally formed with the boss 115, or the body 113 and the boss 115 may be connected as separate two structures, for example, by bonding or otherwise.

In some embodiments, the liquid outlet 1113 may be disposed on a side of the boss 115 away from the body 113, so that when the atomizer 10 is inverted, the liquid in the buffer space 330 is accumulated on the surface of the body 113, but is difficult to enter the liquid guide hole 111 through the liquid outlet 1113, which is helpful for improving the situation that the liquid in the buffer space 330 enters the atomization space 310, and improving the liquid leakage preventing performance of the atomizer 10.

The side of the boss 115 away from the body 113 may be referred to as an end surface 1155 of the boss 115 or an outer surface of the boss 115.

In some embodiments, the liquid outlet 1113 may be disposed at an end surface 1155 of the boss 115 facing away from the body 113, the atomizer 10 may have a wall surface 370 opposite to the end surface 1155, the buffer space 330 is disposed between the wall surface 370 and the body 113, and a distance (L1 in fig. 3) between the end surface 1155 and the wall surface 370 is less than or equal to 50% of a distance (L2 in fig. 3) between the wall surface 370 and the body 113 (e.g. L2 in fig. 3), so that a height of the boss 115 protruding from the body 113 may be increased, when the atomizer 10 is inverted, liquid in the buffer space 330 is accumulated between an outer surface of the boss 115 and the body 113, and it is difficult for the liquid in the buffer space 330 to enter the liquid guiding hole 111 through the liquid outlet 1113, which helps to improve a situation that the liquid in the buffer space 330 flows into the atomizing space 310. In addition, the space occupied by the boss 115 in the buffer space 330 is reduced, and the liquid storage capacity of the buffer space 330 is increased.

For example, the distance between end surface 1155 and wall surface 370 may be 50%, 40%, 30%, 20%, or other values between (0, 50%) of the distance between wall surface 370 and body 113. For example, the distance between body 113 and wall surface 370 is 10mm, and the distance between end surface 1155 and wall surface 370 may be 5mm, 4mm, 3mm, 2mm, or other values.

Wherein the wall 370 may be a wall within the housing assembly 300, for example, the wall 370 may be a bottom surface within the housing assembly 300.

In some of these embodiments, the distance between end surface 1155 and wall surface 370 is greater than or equal to 10% of the distance between the wall surface and body 113, thereby helping to avoid an uneven flow of liquid due to too small a gap between boss 115 and wall surface 370.

Wherein, the distance between the end surface 1155 and the wall surface 370 is less than or equal to 50% of the distance between the wall surface and the body 113 and is greater than or equal to 10% of the distance between the wall surface and the body 113, so that not only the situation that the liquid in the buffer space 330 flows into the atomizing space 310 can be improved, but also the situation that the liquid flow is not smooth due to too small gap between the boss 115 and the wall surface 370 can be avoided.

For example, the distance between the end face 1155 and the wall 370 may be 50%, 40%, 30%, 10%, or (10%, 50%) of the distance between the wall 370 and the body 113.

In some embodiments, the inner diameter of the liquid guiding hole 111 is reduced from the atomizing space 310 to the buffer space 330, so that the liquid guiding hole 111 may be approximately funnel-shaped, and the liquid in the atomizing space 310 may flow into the buffer space 330 along the inner wall of the liquid guiding hole 111 more smoothly.

The shape of the liquid guiding hole 111 may be a substantially funnel shape, such as a conical funnel, a quadrangular funnel, a semicircular funnel, an oval funnel, etc., and specifically, the shape of the liquid inlet 1111 may be a substantially circular shape, a quadrangular shape, a semicircular shape, an oval shape, etc. The shape of the liquid outlet 1113 may be the same as or different from the liquid inlet 1111.

In some embodiments, the outer diameter of the boss 115 may decrease from the atomizing space 310 toward the buffer space 330, thereby helping to reduce the space occupied by the boss 115 in the buffer space 330, so that the buffer space 330 may accommodate more liquid, and the liquid storage capacity of the buffer space 330 is improved.

Referring to fig. 4 to 5, in some embodiments, the atomizer 10 may further include a unidirectional conducting member 130, where the unidirectional conducting member 130 may be connected to an end of the boss 115 away from the body 113 and located in the buffer space 330, and the unidirectional conducting member 130 is configured to conduct the liquid guiding hole 111 from the atomizing space 310 to the buffer space 330, and to close the liquid guiding hole 111 from the buffer space 330 to the atomizing space 310, so that the liquid in the atomizing space 310 may flow into the buffer space 330 through the liquid guiding hole 111, and the liquid in the buffer space 330 may not flow into the accommodating space through the liquid guiding hole 111, thereby improving the leak-proof performance of the atomizer 10.

As an example, the unidirectional flux member 130 may include an elastic member and a rotation plate rotatably coupled to an end of the boss 115 facing away from the body 113. The rotating plate has a first position in which the rotating plate blocks the liquid outlet 1113 and a second position in which the rotating plate opens the liquid outlet 1113. The elastic member is connected to the boss 115 and the rotating plate, and the elastic member is configured to provide an elastic force for the rotating plate to rotate to the first position, so that when the gravity of the liquid accumulated in the liquid guiding hole 111 is greater than the elastic force of the elastic member, the rotating plate rotates from the first position to the second position, the liquid outlet 1113 is opened by the rotating plate, the liquid guiding hole 111 is conducted by the unidirectional conducting member 130, and the liquid in the atomizing space 310 enters the buffer space 330 through the liquid guiding hole 111. When the gravity of the liquid in the liquid guiding hole 111 is smaller than the elastic force of the elastic member or no liquid is in the liquid guiding hole 111, the rotating plate rotates from the second position to the first position, the rotating plate shields the liquid outlet 1113, the unidirectional conducting member 130 blocks the liquid guiding hole 111, and the liquid in the buffer space 330 cannot enter the atomization space 310 through the liquid guiding hole 111. In addition, since the unidirectional conducting element 130 is connected to the end of the boss 115 away from the body 113, the elastic force of the elastic element can be increased, so that more liquid needs to be accumulated in the liquid guiding hole 111 to overcome the elastic force of the elastic element, which is helpful to prevent the liquid guiding hole 111 from being conducted by the unidirectional conducting element 130 when the atomizer 10 is slightly swayed, thereby causing the liquid in the buffer space 330 to flow into the atomization space 310 and causing liquid leakage.

As another example, unidirectional current conducting member 130130 may comprise a rotating plate rotatably connected to an end of boss 115 facing away from body 113. When the user uses the atomizer 10, for example, when the atomizing nozzle of the atomizer 10 is facing upwards, the liquid outlet 1113 is opened by the rotating plate under the action of gravity, the unidirectional conducting member 130 conducts the liquid guiding hole 111, and the liquid in the atomizing space 310 enters the buffer space 330 through the liquid guiding hole 111. When the user does not use the atomizer 10, for example, when the atomizing nozzle of the atomizer 10 faces downward, that is, when the atomizer 10 is inverted, the rotating plate is covered on the liquid outlet 1113 under the action of gravity, the unidirectional conducting member 130 cuts off the liquid guiding hole 111, and the liquid in the buffer space 330 cannot enter the atomizing space 310 through the liquid guiding hole 111.

It should be noted that, in the above example, the structure of the unidirectional conductive member 130 is merely taken as an example for understanding, and other structures of the unidirectional conductive member 130, such as a unidirectional valve or other unidirectional conductive structures, may also be used, which is not limited in this application.

It can be appreciated that by providing the unidirectional conductive member 130, the liquid in the buffer space 330 can be effectively prevented from flowing to the atomizing space 310, so that the areas of the liquid inlet 1111 and the liquid outlet 1113 are not required to be controlled, the areas of the liquid inlet 1111 and the liquid outlet 1113 can be equal or unequal, and the liquid outlet 1113 can be a capillary port or a no capillary port.

In some embodiments, the unidirectional conducting member 130 may be disposed at other positions of the partition member 110 along the axial direction of the liquid guiding hole 111, for example, the unidirectional conducting member 130 may be located in the atomizing space 310 and on a side of the body 113 facing away from the boss 115.

In some embodiments, the surface of the boss 115 facing away from the body 113 may be provided with a receiving groove 1153, and the unidirectional conducting apparatus 130 is at least partially located in the receiving groove 1153, so that the space occupied by the unidirectional conducting apparatus 130 in the buffer space 330 may be reduced, so that the buffer space 330 may accommodate more liquid, and the liquid storage capacity of the buffer space 330 is improved.

In some of these embodiments, the partition 110 is chamfered at the liquid inlet 1111 so that the liquid in the atomizing space 310 can flow into the liquid guiding hole 111 more smoothly. Wherein, the chamfer can be a chamfer or a chamfer angle.

In addition, the atomizer 10 is provided with the boss 115, so that liquid in the buffer space 330 is not easy to enter the atomizing space 310 through the liquid guide hole 111, and liquid in the atomizing space 310 is easy to enter the buffer space 330 through the liquid guide hole 111, thereby being beneficial to reducing the situation that the liquid in the buffer space 330 flows into the atomizing space 310, and further improving the liquid leakage preventing performance of the atomizer 10. In addition, the atomizer 10 of this application embodiment can be with the leading-in buffer memory space 330 of liquid in the atomizer space 310, need not to use the stock solution cotton, has reduced manufacturing cost, and prevent buffer memory space 330 and compare the stock solution cotton can hold more liquid, the difficult entering atomizer space 310 of liquid in the buffer memory space 330 has promoted the leak protection performance of atomizer 10, also can avoid the weeping to be atomized and influence the quality of the aerosol that the atomizing formed.
