It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The side atomization means that the atomization core is longitudinally arranged relative to the cartridge tube, so that the occupied space of the atomization core in the cartridge tube can be effectively saved. However, in the side atomization scheme, aerosol particles led out by atomization of the atomization core are easy to clap to the opposite side wall surface, so that the aerosol particles are condensed and flow back, and if condensate cannot be effectively recovered, the condensate is easy to be sucked into the inlet cavity by a smoker, and suction experience is affected. Particularly for some special high-viscosity tobacco tar, if condensate cannot be effectively recovered, the condensate can flow into an air passage to be deposited, so that the air passage is blocked, and finally suction cannot be performed.

In order to solve the above problems, the present inventors have developed an aerosol generating device, which can reduce the risk of condensate being sucked into the oral cavity by a user by collecting the condensed reflux liquid through an oil groove provided below a side wall disposed opposite to an air outlet face of an atomizing core, and can reduce the possibility of condensate depositing to block an air passage.

Referring to fig. 1 and 2, an aerosol generating device according to an embodiment of the present application includes a battery assembly 2000, an atomizing assembly 1000 and a suction nozzle 3000; the battery assembly 2000 is electrically connected with the atomizing assembly 1000, and the battery assembly 2000 is used for supplying power to the atomizing assembly 1000 so as to start atomizing the atomizing assembly 1000; the atomizing assembly 1000 is for atomizing tobacco tar into aerosol particles; the mouthpiece 3000 communicates with the atomizing assembly 1000 and is used to deliver aerosol particles generated by the atomizing assembly 1000 to the mouth of the smoker.

Referring to fig. 3 to 6, the atomizing assembly 1000 includes a housing assembly 100 and an atomizing core 200, wherein an atomizing chamber 160 is formed in the housing assembly 100, the atomizing core 200 is longitudinally disposed in the atomizing chamber 160, and the atomizing core 200 has an air outlet surface 220 for atomizing air; the housing assembly 100 further includes a first oil groove 600 formed therein, the housing assembly 100 includes a guide wall 1111 disposed opposite to the air outlet surface 220 of the atomizing core 200, the first oil groove 600 is formed at a bottom of a side of the guide wall 1111 facing the atomizing core 200, the guide wall 1111 is one of side walls of the first oil groove 600, and the guide wall 1111 is used for guiding condensate into the first oil groove 600.

It should be noted that, the longitudinal direction refers to a direction extending along substantially the entire axial direction of the atomizing assembly 1000, for example, the atomizing core 200 is disposed along a direction parallel to the axial direction of the atomizing assembly 1000, or the atomizing core 200 is disposed at an inclined angle to the axial direction of the atomizing assembly 1000, and generally, the extending direction of the atomizing core 200 is the same as the axial direction of the atomizing assembly 1000, and the inlet face 210 and the outlet face 220 of the atomizing core 200 are disposed substantially parallel to the air flow direction in the atomizing chamber 160. In fact, in the design, the thickness between the inlet face 210 and the outlet face 220 of the block-shaped atomizing core 200 is generally designed to be smaller, and the area of the outlet face 220 of the atomizing core 200 is designed to be larger, so that the transverse occupation space of the atomizing core 200 can be reduced due to the design that the atomizing core 200 is longitudinally installed in the atomizing chamber 160.

Correspondingly, the transverse direction here is the direction perpendicular to the longitudinal direction, i.e. the horizontal direction when the aerosol-generating device is placed vertically.

In addition, the guide wall 1111 is one of the side walls of the first oil tank 600, that is, the first oil tank 600 is formed by the guide wall 1111 and other side walls, when condensate exists on the guide wall 1111, the guide wall 1111 can guide the condensate into the first oil tank 600. The first oil groove 600 is disposed at the bottom of the guide wall 1111, so that condensate can flow to the first oil groove 600 under the gravity of the condensate without external force.

In the embodiment of the present application, since the atomizing core 200 is longitudinally disposed in the atomizing bin 160, aerosol particles atomized by the atomizing core 200 are guided out transversely from the air outlet surface 220 of the atomizing core 200, as shown in fig. 6, when aerosol particles are guided out transversely, the aerosol particles tend to beat the opposite guide wall 1111, and because the temperature of the guide wall 1111 is relatively low compared with the aerosol particles, the aerosol particles beating on the guide wall 1111 tend to condense and flow back. The guiding wall 1111 guides the condensate downward into the first oil groove 600, and the condensate is collected by the first oil groove 600, so that the risk that the condensate is sucked into the oral cavity by a user due to deposition is reduced, and the suction experience of the user is improved; meanwhile, since the first oil groove 600 collects condensate, the risk of the condensate blocking the air flow channel due to excessive deposition can be reduced, the air flow of the aerosol generating device is ensured to be smooth, and the service life of the aerosol generating device is prolonged.

In one embodiment, referring to fig. 6, the top of the first oil sump 600 is longitudinally below the bottom of the atomizing core 200 such that condensate directed from the air exit face 220 of the atomizing core 200 and flowing onto the flow guide wall 1111 can flow to the first oil sump 600 and be collected.

In one embodiment, referring to fig. 7, the guide wall 1111 is an arc wall extending along a longitudinal straight line, and the guide wall 1111 is disposed towards the atomizing core 200, so that the condensate can be collected into the first oil groove 600 as much as possible through the effect of the guide wall 1111 on condensing the condensate, thereby improving the collection effect of the condensate.

In one embodiment, referring to fig. 7, the housing assembly 100 is formed with the air intake passage 440, and the first oil groove 600 extends around the air intake passage 440, so that the collecting range of condensate from the first oil groove 600 can be enlarged, and the volume of the first oil groove 600 can be increased as much as possible without affecting the air intake passage 440.

In one embodiment, referring to fig. 7, opposite ends of the first oil groove 600 are disposed near the atomizing core 200, respectively, that is, the length of the first oil groove 600 in the circumferential direction is enlarged as much as possible, so that condensate that comes out of the atomizing core 200 and is caught on the guide wall 1111 can be guided into the first oil groove 600.

In one embodiment, referring to fig. 7, the atomizing core 200 and the first oil groove 600 are respectively located at opposite sides of the air inlet channel 440 of the housing assembly 100, such that the arrangement of the atomizing core 200 and the first oil groove 600 does not affect the fluidity of the air inlet channel 440.

In one embodiment, referring to fig. 8, an absorbent cotton 500 for absorbing condensate is disposed in the first oil tank 600, and by the arrangement of the absorbent cotton 500, the condensate can be absorbed, so that the storage space of the first oil tank 600 is indirectly increased, and the first oil tank 600 can collect larger condensate, thereby reducing the situation of liquid leakage and hole blockage.

Alternatively, the absorbent cotton 500 may be compressed molding cotton, which expands in volume after absorbing condensate, and the molding cotton may expand to protrude out of the first oil groove 600, so that the collecting effect of the first oil groove 600 may be increased. In addition, the size of the molding cotton itself may be designed to be relatively high, and the molding cotton may be protruded beyond the first oil groove 600, so that condensate on the guide wall 1111 may be directly absorbed by the absorbing cotton. It will be appreciated that in other embodiments of the application, the absorbent cotton may also be a sponge or asbestos, not being limited solely herein.
