The open end of the housing 10 opposite to the suction nozzle opening 110 is fixedly coupled with a bottom cover 40, and the bottom cover 40 includes a base 41 covering the open end of the housing 10, and a sidewall 42 disposed around the inner wall surface of the housing 10. A first flange 421 is formed between the upper end surface of the base 41 and the side wall 42 to facilitate a fixed connection between the ends of the housing 10. The base 41 is fixedly connected with a positive electrode 70, and the positive electrode 70 penetrates through the base 41 and extends longitudinally along the housing 10 to be electrically connected with two ends of the heating element 22. The atomizer 100 is electrically connected to the power supply apparatus 200 through the positive and negative electrodes 70, so that the power supply apparatus 200 provides electric drive for the atomizing assembly 20.

Specifically, the partition 50 is substantially boat-shaped and includes supporting portions 51 with raised end portions on both sides, the supporting portions 51 are at least partially sleeved outside the side walls 42 of the bottom cover 40, the side walls 42 of the bottom cover 40 are provided with second flanges 421, and the lower end surfaces of the main body portions 51 are in longitudinal abutment with the upper end surfaces of the second flanges 421. And the supporting part 51 is arranged around the inner wall surface of the shell 10, and the outer surface of the supporting part 51 is provided with a circle of reinforcing ribs 511 so as to be further and fixedly connected to the inner wall surface of the shell 10 in a sealing way. The partition 50 further comprises a body portion 52 disposed at least partially opposite the atomizing face 212, the area between the body portion 52 and the atomizing face 212 being the atomizing chamber 23. The main body 52 is provided with a vent hole 53 communicating with the air inlet 90, and the vent hole 53 is located substantially in the middle of the main body 52 and is disposed so as to face the atomizing surface 212. Since the first air inlet 91 and the second air inlet 92 are provided near the end of the side wall 42, i.e., the air inlet 90 is completely offset from the air vent 53 along a projection plane perpendicular to the longitudinal direction of the housing 10. And the air outlet ends of the vent hole 53 and the air outlet ends of the first air inlet 91 and the second air inlet 92 are higher than the surrounding plane, so that condensate formed by aerosol in the atomization cavity 23 when the aerosol is cooled or leaked liquid matrix is difficult to directly enter the air inlet 90 through the vent hole 53, and liquid can be prevented from leaking to the outside of the atomizer 100.
Further, the projected area of the main body portion 52 on the bottom cover 40 in the longitudinal direction of the housing 10 is larger than the projected area of the atomizing face 212 on the bottom cover 40 in the longitudinal direction of the housing 10. Two ends of the main body 52 are respectively connected with the supporting part 51 through two partition plates 54, as the two sides of the supporting part 51 are bulged, the partition plates 54 are obliquely arranged, a plurality of drainage ports 55 are formed between the adjacent partition plates 54 and between the partition plates 54 and the inner wall surface of the supporting part 51, and inclined surfaces are arranged at two end surfaces of the main body 52, so that liquid on the main body 52 can conveniently enter the drainage ports 55. A part of the wall surface of the partition plate 54 of the partition 50 is disposed in abutment with the inner wall surface of the bottom cover 40, a first liquid collection area 561 is formed between the partition plates 54, and a second liquid collection area 562 is formed in the area between the partition 50 and the base 41 of the bottom cover 40. Along the longitudinal direction of the casing 10, the partition plates 54 and the liquid guide openings 55 at two sides of the partition member 50 are opposite to the air outlet channels 14 at two sides of the casing 10, and condensate or part of liquid matrix formed in the air outlet channels 14 can enter the partition plates 54 or the liquid guide openings 55 at two sides of the partition member 50 under the action of gravity, so that the condensate or part of liquid matrix enters the first liquid collecting area 561 or the second liquid collecting area 562, thereby greatly improving the leak-proof performance of the whole atomizer 100.
Still further, since the reservoir 16 is essentially a sealed chamber, the atomizing assembly 20 is accessible through the opening 171, except for the liquid matrix. As the liquid matrix within the reservoir 16 is consumed, the gas space increases, creating a negative pressure, which results in the liquid matrix not being able to smoothly enter the atomizing assembly 20 from the opening 171.
Based on the above, the present application provides an embodiment of an atomizing assembly comprising a porous body 21 and a heating element 22, wherein a vent groove 80 is provided on the porous body 21, one end of the vent groove 80 is connected to the atomizing chamber 23, and the other end is connected to the liquid storage chamber 16. Because the atomizing chamber 23 is communicated with the air inlet 90, when negative pressure is formed inside the liquid storage chamber 16, air can be supplemented through the ventilation groove 80, so that liquid guiding is smooth. Specifically, the first section 801 of the vent groove 80 is located on the liquid suction surface 211 of the porous body 21, the first section 801 extends on the liquid suction surface 211 to form a termination end 8011, and the sealing member 30 covers a portion of the liquid suction surface 211 but does not cover the termination end 8011 of the first section 801, so that the termination end 802 of the first section 801 is in fluid communication with the liquid storage chamber 16. The second section 802 of the vent slot 80 is located on at least one of the sides 24 of the porous body 21 with one end thereof in communication with the first section 801 and extends over the side 24, and at most extends into communication with the atomizing face 212. Since at least a portion of the outer surface of the side 24 is covered by the seal 30, the second segment 802 of the vent slot 80 extends longitudinally as much as possible such that at least a portion of the other end of the second segment 802 is uncovered by the seal 30 and is in fluid communication with the nebulization chamber 23 to facilitate the passage of air from within the nebulization chamber 23 into the vent slot 80. Since the vent groove 80 is defined by grooves formed on the surface of the porous body 21 and extends at least on both surfaces thereof, the first section 801 is connected to the liquid storage chamber 16, and the second section 802 is connected to the outside air through the atomizing chamber 23, even if the sealing member 30 on the surface of the porous body 21 is tightly adhered to the outer surface of the porous body 21, the vent groove 80 is not closed and does not obstruct the air flow into the liquid storage chamber 16, and on the other hand, the air outlet end of the vent groove 80 is the end 802 of the first section 801 is located on the liquid suction surface 211 and is closer to the atomizing surface 212, even if the viscosity of the liquid substrate is higher or the flow is slower, the liquid substrate in the vent groove 80 can be continuously transferred to the atomizing surface 212 for atomization, and the air flow into the liquid storage chamber 16 is not affected. Alternatively, when the relative positional relationship between the liquid-absorbing surface 211 and the atomizing surface 212 of the porous body 21 is changed, the vent grooves 80 may extend longitudinally on one of the side surfaces 24 of the porous body 21 until connected to the liquid-absorbing surface 211, i.e., only by allowing one end of the vent grooves 80 on the surface of the porous body 80 to be in fluid communication with the liquid-storage chamber 16 and the other end to be in fluid communication with the external air flow.
In the preferred embodiment provided by the present application, the vent grooves 80 include a first vent groove 81 and a second vent groove 82 which are isolated from each other, the first vent groove 81 being disposed opposite to the second vent groove 82, and being symmetrical about the center of the porous body 21.
