It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1, 2 and 3, the present invention provides an atomizer 10 including an atomizing core 100, a base assembly 200 and a housing 310, wherein the housing 310 is used for accommodating the base atomizing core 100 and the base assembly 200, and the atomizing core 100, the base assembly 200 and the housing 310 jointly enclose an atomizing chamber 320. The housing 310 further defines a suction hole 311, and the suction hole 311 communicates the outside with the atomizing chamber 320. The atomizing wick 100 is disposed on the base assembly 200 and has a first surface 110, and an aerosol-generating substrate, such as a liquid, buffered on the atomizing wick 100 can be atomized on the first surface 110 to form an aerosol that will be discharged into the atomizing chamber 320 first. The base assembly 200 has a second surface 221, the second surface 221 is disposed toward the first surface 110, the first surface 110 is disposed downward, the second surface 221 is disposed upward, and both the first surface 110 and the second surface 221 may be planar. Both the first surface 110 and the second surface 221 together define part of the boundary of the nebulizing chamber 320. The first surface 110 and the second surface 221 are spaced apart by a certain distance in the axial direction (up-down direction) of the atomizer 10. When a user draws on the end of the inhalation aperture 311, aerosol in the nebulizing chamber 320 can enter the inhalation aperture 311 and be absorbed by the user.

In some embodiments, referring to fig. 2, 3 and 4, the base assembly 200 includes a base 210 and a filling member 220, the filling member 220 may be a silicone filling member made of a silicone material, the filling member 220 is disposed on the base 210, the base 210 is provided with an air inlet 211 and an air vent 212, the air inlet 211 is communicated with the outside, the base 210 further has an inner wall surface 213 and an abutting surface 214, the inner wall surface 213 defines a partial boundary of the air inlet 211, the abutting surface 214 is located outside the air inlet 211 and contacts with the filling member 220, the air vent 212 penetrates through the inner wall surface 213 and the abutting surface 214, and obviously, the air vent 212 is directly communicated with the air inlet 211. The aperture of the vent hole 212 is smaller than the aperture of the air inlet hole 211, the number of the vent holes 212 may be multiple, and the plurality of vent holes 212 may be uniformly distributed on the abutting surface 214. The contact surface 214 is curved, and the distance from the contact surface 214 to the first surface 110 gradually increases from the center of the contact surface 214 to the edge of the contact surface 214, and in general, the contact surface 214 has a shape with a high middle and a low edge. Both the intake holes 211 and the vent holes 212 may be cylindrical holes.

The filling member 220 is provided with an air hole 222, the air hole 222 penetrates the entire filling member 220 along the axial direction of the atomizer 10, and obviously, the air hole 222 penetrates the second surface 221, which can be understood as the air hole 222 is provided on the second surface 221. The air guide holes 222 communicate the atomizing chamber 320 with the air vent holes 212, so that the air vent holes 212 communicate between the air inlet holes 211 and the air guide holes 222. The aperture of the air guide hole 222 may be greater than or equal to the aperture of the air intake hole 211. Along the direction (i.e. from top to bottom) that the air guide hole 222 points to the air inlet hole 211, that is, the direction that the first surface 110 points to the second surface 221, the aperture of the air guide hole 222 gradually decreases, so that the air guide hole 222 is a tapered hole with a large top and a small bottom, and the air guide hole 222 can be arranged coaxially with the air inlet hole 211. When a user sucks on the end of the suction hole 311, the external air enters the atomizing chamber 320 through the air inlet holes 211, the vent holes 212 and the air guide holes 222 in sequence to carry the aerosol, and finally the external air enters the suction hole 311 to be absorbed by the user, and the dotted arrows in fig. 2 represent other flow paths.

The cross-section of the air-guide hole 222 is one of circular, oval, rectangular or regular polygonal. In general, when the cross section is circular or elliptical, the air holes 222 are truncated cone-shaped holes. When the cross section is rectangle or other regular polygon, air guide hole 222 is the frustum of a prism shape hole, for example can be four frustum of a prism shape holes, of course, in the manufacturing process, can carry out the chamfer to the edges and corners department in the air guide hole 222, so can reduce the hindrance effect of edges and corners to gas, reduce the flow resistance of gas in air guide hole 222 to make the air current get into atomizing chamber 320 with faster speed, make the aerosol leave atomizing chamber 320 fast then, avoid detaining the aerosol in atomizing chamber 320 and form the condensate.

The aperture of the air guide hole 222 is gradually reduced in the direction from the first surface 110 to the second surface 221, so that the eddy generated when the gas in the air guide hole 222 is input to the edge of the atomizing chamber 320 can be reduced, the eddy is prevented from weakening the local air flow velocity in the atomizing chamber 320, the air flow output from the air guide hole 222 is more uniformly distributed in the atomizing chamber 320, the flow velocity of the aerosol at each position in the atomizing chamber 320 is ensured to be consistent, the aerosol with the slower flow velocity is prevented from being retained in the atomizing chamber 320, the aerosol at each position in the atomizing chamber 320 is ensured to flow out at a higher flow velocity, the probability that the aerosol is retained in the atomizing chamber 320 due to the slower flow velocity is reduced, the actual suction amount of the aerosol by a user is increased, and the possibility that condensate is formed due to the larger retained aerosol amount and leaks out of the atomizer 10 is also reduced.

Meanwhile, the air inlet hole 211 and the air guide hole 222 are coaxially arranged, so that the on-way resistance of the outside air in the air inlet hole 211 and the air guide hole 222 can be reduced, the outside air entering the atomizing cavity 320 is ensured to keep a high flow speed so as to carry aerosol to rapidly enter the air suction hole 311 to be absorbed by a user, the actual suction amount of the aerosol by the user can be further improved, and the leakage of condensate is reduced. Moreover, the abutting surface 214 is high in the middle and low in the edge, so that the condensate falling from the air guide hole 222 to the abutting surface 214 can quickly flow out of the abutting surface 214 under the action of gravity, and the condensate is prevented from entering the air vent 212 and leaking from the air inlet hole 211 due to long staying time on the abutting surface 214.

Moreover, if the atomizing core 100, the base 210 and the housing 310 together enclose the atomizing chamber 320 without the filler 220 on the base 210, the dimension of the atomizing chamber 320 between the atomizing surface and the base 210 along the axial direction of the atomizer 10 may be higher than 2.6mm, which results in a larger volume of the entire atomizing chamber 320, thereby causing at least the following disadvantages: firstly, the flow velocity of the aerosol carried by the external gas in the atomizing chamber 320 with a large volume is slow, and the aerosol cannot leave the atomizing chamber 320 quickly, so that a considerable part of the aerosol stays in the atomizing chamber 320 and cannot be absorbed by the user, thereby reducing the amount of the aerosol actually sucked by the user in unit time. Secondly, the atomizing chamber 320 with a large volume can accommodate more retained aerosol, and also increases the contact area between the retained aerosol and the base assembly 200 and the housing 310, that is, the retained aerosol is more easily cooled and liquefied by heat exchange to form a condensate rapidly, and the condensate flows out of the atomizer 10 through the air guide holes 222, the vent holes 212 and the air inlet holes 211, so that the atomizer 10 generates liquid leakage.

In the atomizer 10 of the above embodiment, the base 210 is further provided with the filler 220, so that the atomizing core 100, the base 210, the filler 220 and the outer shell 310 together enclose the atomizing chamber 320, thereby greatly reducing the volume of the entire atomizing chamber 320. At this time, in view of the first surface 110 and the second surface 221 being spaced apart in the axial direction (up-down direction) of the atomizer 10, a certain spacing distance H is formed, which is actually the dimension of the portion of the atomizing chamber 320 between the first surface 110 and the second surface 221 in the axial direction of the atomizer 10. When the separation distance H is smaller, the volume of the entire nebulizing chamber 320 will be smaller, i.e., the separation distance H is proportional to the volume of the nebulizing chamber 320. The spacing distance H ranges from 0.8mm to 1.2mm, for example, it may specifically take the value of 0.8mm, 0.9mm, 1.0m or 1.2 mm.

Therefore, when the volume of the atomizing chamber 320 is reduced, on one hand, under the same suction force of the user, the flow velocity of the aerosol carried by the outside air in the atomizing chamber 320 with a smaller volume is faster, the aerosol will leave the atomizing chamber 320 quickly, it is ensured that most of the aerosol leaves the atomizing chamber 320 quickly and is absorbed by the user, the retention amount of the aerosol in the atomizing chamber 320 is reduced, thereby increasing the amount of the aerosol actually sucked by the user in a unit time, on the other hand, the less amount of the aerosol is retained in the atomizing chamber 320 with a smaller volume, the contact area between the retained aerosol and the base assembly 200 and the housing 310 is reduced, it is ensured that the retained aerosol is difficult to be cooled and liquefied quickly through heat exchange to form condensate, so the retained aerosol has a relatively higher temperature and can be discharged to the outside through the suction holes 311, and the retained aerosol is prevented from forming condensate in the atomizing chamber 320, preventing the condensate from leaking out of the atomizer 10 and creating a liquid leak.

The second surface 221 of the filling member 220 is formed with a recess, which can be disposed around the air-guiding hole 222, so that even when the aerosol staying in the atomizing chamber 320 forms condensate, the recess can accommodate the condensate, thereby preventing the condensate from flowing out of the atomizer 10 through the air-guiding hole 222, the air-guiding hole 212 and the air-inlet hole 211, and preventing the atomizer 10 from leaking the liquid.

In some embodiments, the chassis assembly 200 further comprises a wicking member 230. Specifically, the base assembly 200 includes a base 210, a filling member 220 and a liquid absorbing member 230, the filling member 220 may be a silicone filling member 220 made of a silicone material, the filling member 220 is disposed on the base 210, the base 210 is provided with an air inlet 211 and an air vent 212, the air inlet 211 is communicated with the outside, the base 210 further has an inner wall surface 213 and an abutting surface 214, the inner wall surface 213 defines a partial boundary of the air inlet 211, the abutting surface 214 is located outside the air inlet 211 and is in contact with the filling member 220, the air vent 212 simultaneously penetrates through the inner wall surface 213 and the abutting surface 214, and obviously, the air vent 212 is directly communicated with the air inlet 211. The aperture of the vent hole 212 is smaller than the aperture of the air inlet hole 211, the number of the vent holes 212 may be multiple, and the plurality of vent holes 212 may be uniformly distributed on the abutting surface 214. The contact surface 214 is curved, and the distance from the contact surface 214 to the first surface 110 gradually increases from the center of the contact surface 214 to the edge of the contact surface 214, and in general, the contact surface 214 has a shape with a high middle and a low edge. Both the intake holes 211 and the vent holes 212 may be cylindrical holes.

The filling member 220 is provided with an air hole 222, the air hole 222 penetrates the entire filling member 220 along the axial direction of the atomizer 10, and obviously, the air hole 222 penetrates the second surface 221, which can be understood as the air hole 222 is provided on the second surface 221. The air guide holes 222 communicate the atomizing chamber 320 with the air vent holes 212, so that the air vent holes 212 communicate between the air inlet holes 211 and the air guide holes 222. The aperture of the air guide hole 222 may be greater than or equal to the aperture of the air intake hole 211. Along the direction (i.e. from top to bottom) that the air guide hole 222 points to the air inlet hole 211, the aperture of the air guide hole 222 gradually decreases, so that the air guide hole 222 is a tapered hole with a large top and a small bottom, and the air guide hole 222 can be coaxially arranged with the air inlet hole 211. When a user sucks on the end of the air suction hole 311, the external air enters the atomizing chamber 320 through the air inlet holes 211, the vent holes 212 and the air guide holes 222 in sequence to carry the aerosol, and finally the external air enters the air suction hole 311 to be absorbed by the user with the aerosol.

The cross section of the air hole 222 is circular or regular polygon, and in popular terms, when the cross section is circular, the air hole 222 is a circular truncated cone-shaped hole. When the cross section is a regular polygon, the air vent 222 is a truncated pyramid shaped hole, for example, a truncated quadrangular pyramid shaped hole, and of course, in the manufacturing process, the corners in the air vent 222 may be chamfered.

In the atomizer 10 of the above embodiment, the base 210 is further provided with the filler 220, so that the atomizing core 100, the base 210, the filler 220 and the outer shell 310 together enclose the atomizing chamber 320, thereby greatly reducing the volume of the entire atomizing chamber 320. At this time, in view of the first surface 110 and the second surface 221 being spaced apart in the axial direction (up-down direction) of the atomizer 10, a certain spacing distance is formed, which is actually the dimension of the portion of the atomizing chamber 320 between the first surface 110 and the second surface 221 in the axial direction of the atomizer 10. When the separation distance is smaller, the volume of the entire nebulizing chamber 320 will be smaller, i.e., the separation distance is proportional to the volume of the nebulizing chamber 320. The spacing distance ranges from 0.8mm to 1.2mm, for example, the spacing distance may specifically range from 0.8mm, 0.9mm, 1.0m, or 1.2 mm.

The cone-shaped liquid absorbing member 230 is connected with the filling member 220 and covers the air vent 222, and the liquid absorbing member 230 is provided with a through hole 231 penetrating through the whole liquid absorbing member 230. The through hole 231 communicates the upper portion of the gas hole 222 with the lower portion of the gas hole 222, i.e. the liquid absorbing member 230 does not completely close the gas hole 222, so as to ensure that the gas in the lower portion of the gas hole 222 can enter the upper portion of the gas hole 222 through the through hole 231, and then continue to enter the atomizing chamber 320. In short, the liquid absorbing member 230 provided with the penetration hole 231 does not prevent the gas from flowing from the gas inlet hole 211 into the atomizing chamber 320, in other words, the liquid absorbing member 230 does not prevent the flow of the gas. The liquid absorbing member 230 can be made of cotton material, when the condensate formed in the atomizing chamber 320 falls into the air guide holes 222, most of the condensate entering the air guide holes 222 will be absorbed on the liquid absorbing member 230 due to the covering effect of the liquid absorbing member 230, that is, the liquid absorbing member 230 can have a considerable blocking effect on the flow of the condensate, and the condensate is prevented from continuously entering the air inlet holes 211 and leaking out of the atomizer 10. Thereby improving the leak resistance of the atomizer 10.

Referring to fig. 6, the utility model provides an electronic atomization device 30 still, this electronic atomization device 30 includes power 20 and atomizer 10, and power 20 and atomizer 10 can be dismantled the connection, and power 20 supplies power to atomizing core 100, and atomizing core 100 turns into heat energy with the electric energy for liquid on the atomizing surface 110 absorbs heat energy and atomizes and form the aerosol that can supply the user to aspirate. The power supply 20 can be recycled for many times in a charging mode, and after the electric quantity of the power supply is consumed, the power line of the external charging equipment is matched with a charging socket on the power supply 20, so that the power supply 20 is charged. While the atomizer 10 may be a disposable consumable, after all of the liquid in the atomizer 10 has been atomized, the atomizer 10 may be unloaded from the power supply 20 and discarded, and a new atomizer 10 filled with liquid may be reinstalled on the power supply 20. By arranging the atomizer 10, on one hand, the electronic atomization device 30 can meet the requirement of a user on the large aerosol amount by meeting the requirement of the user on the high aerosol suction amount in unit time. On the other hand, the condensate in the atomizer 10 can be prevented from leaking into the power supply 20 through the air inlet 211, the condensate can be prevented from corroding the power supply 20 and even exploding the power supply 20, and the service life and the safety of the electronic atomization device 30 are improved.
