The width and/or depth of the end of the drainage groove 114 close to the ventilation groove 112 is smaller than the width and/or depth of the end of the drainage groove 114 close to the liquid storage groove 113, that is, the width and/or depth of the drainage groove 114 increase in a gradient manner along the direction from the ventilation groove 112 to the liquid storage groove 113, and the specific setting of the gradient is designed according to requirements. The width of one end of the drainage groove 114 far away from the liquid storage cavity 13 is 0.2mm-1.5mm, and the depth is 0.2mm-1.5 mm; the width of one end of the drainage groove 114 close to the liquid storage cavity 13 is 0.2mm-1.5mm, and the depth is 0.2mm-1.5 mm. That is, the width of the drainage groove 114 is 0.2mm to 1.5mm, and the depth is 0.2mm to 1.5 mm. Preferably, the width of the drainage groove 114 at the end near the reservoir 13 is 0.4mm and the depth is 0.3 mm.

One side of the longitudinal section of the flow guide groove 114 is parallel to the length direction of the atomizing base 11, so that the flow guide groove 114 is easy to form and is in smooth transition with the shell 10, and the assembly reliability and the yield are improved.

By setting the width and/or depth of the end of the drainage groove 114 close to the ventilation groove 112 to be smaller than the width and/or depth of the end of the drainage groove 114 close to the liquid storage groove 113, when the liquid in the ventilation groove 112 on the outer surface of the atomization top seat 115 flows to the gap between the atomization top seat 115 and the atomization base 116, the drainage groove 114 on the atomization base 116 drains the liquid into the liquid storage groove 113, and the leakage formed by the ventilation groove 112 is prevented from climbing to the air outlet channel 14 along the gap between the atomization seat 11 and the housing 10 to cause the suction leakage. And due to the inclined design of the drainage groove 114, the liquid can more easily enter the liquid storage groove 113 for storage and is not easy to reversely flow out of the liquid storage groove 113.

Referring to fig. 5-7, fig. 5 is a schematic longitudinal cross-sectional view of an embodiment of a flow guide slot in an atomizing assembly provided herein, fig. 6 is a cross-sectional view of the atomizing assembly of fig. 2B taken along the direction B-B, and fig. 7 is a schematic longitudinal cross-sectional view of another embodiment of a flow guide slot in an atomizing assembly provided herein.

In one embodiment, the width of the drainage channel 114 gradually increases in a direction away from the reservoir 13, i.e., the width of the drainage channel 114 gradually increases in a direction from the ventilation channel 112 to the reservoir 113 (the width of the drainage channel 114 has a smaller gradient in the direction from the ventilation channel 112 to the reservoir 113), and one side of the longitudinal section of the drainage channel 114 is parallel to the longitudinal direction of the atomizing base 11. Wherein, the section in the width direction parallel to the atomizing component 1 obtains the longitudinal section of the drainage groove 114; the length direction of the atomizing base 11 is the same as the length direction of the atomizing assembly 1. Preferably, the cross-sectional shape of the drainage channel 114 is a right triangle or a right trapezoid (as shown in FIG. 5). The depth of the flow guide groove 114 is gradually increased along the direction close to the central axis of the atomization assembly 1; the cross-sectional shape is triangular (as shown in fig. 5 and 6), i.e., the depth of the flow directing groove 114 increases gradually from zero in the width direction in a direction near the central axis of the atomizing assembly 1. In this embodiment, the overall structure of the drainage groove 114 is triangular frustum-shaped; through setting up drainage groove 114 to the prismoid form for drainage groove 114 easily takes shape, and realizes the smooth transition of drainage groove 114 and casing 10, improves assembly reliability and yield. It will be appreciated that the cross-sectional shape of the gutter 114 can also be isosceles trapezoid, semi-circular, etc., the longitudinal cross-sectional shape of the gutter 114 can also be any other shape, and the cross-sectional shape and the longitudinal cross-sectional shape of the gutter 114 can be designed as desired.

In another embodiment, as shown in FIG. 7, the drainage slots 114 comprise a plurality of sub-drainage slots of different widths. For example, the drainage slots 114 include a first sub-drainage slot 1141 and a second sub-drainage slot 1142, the second sub-drainage slot 1142 being disposed at an end of the first sub-drainage slot 1141 remote from the reservoir 13; the cross-sectional shape and size of the first sub-drainage sink 1141 is constant, the cross-sectional shape and size of the second sub-drainage sink 1142 is constant, and the cross-sectional area of the second sub-drainage sink 1142 is greater than the cross-sectional area of the first sub-drainage sink 1141 (the width of the drainage sink 114 increases with a greater gradient in the direction from the breather 112 to the sump 113). One side of the longitudinal cross-section of the first sub-drainage groove 1141 and one side of the longitudinal cross-section of the second sub-drainage groove 1142 are collinear, and the collinear sides are parallel to the length direction of the atomizing base 11. Wherein the cross-section in the direction parallel to the width of the atomizing assembly 1 results in the longitudinal cross-sections of the first and second

sub-conduction slots

1141 and 1142. In this embodiment, the depths of the first and second

sub-drainage slots

1141 and 1142 are gradually increased from zero in the width direction along the direction close to the central axis of the atomizing assembly 1, so as to realize smooth transition between the drainage slots 114 and the housing 10, and improve the assembly reliability and yield.

The extending direction of the first sub ventilation groove 1121 is perpendicular to the extending direction of the groove in the second sub ventilation groove 1122. The specific structure of the ventilation slot 112 can be designed as required, and ventilation of the liquid storage cavity 13 and communication of the liquid storage cavity 13 and the drainage slot 114 can be realized. The width of the air exchange groove 112 is 0.2mm-1.5mm, and the depth is 0.2mm-1.5 mm; preferably, the width of the air vent groove 112 is 0.3mm and the depth is 0.4 mm. It will be appreciated that a first connecting slot (not shown) is provided at the end of the second sub-aeration slot 1122 adjacent to the drainage slot 114, which connects the aeration slot 112 to the drainage slot 114.

The liquid storage tank 113 includes a plurality of sub liquid storage tanks 1131, and the plurality of sub liquid storage tanks 1131 are arranged in parallel and connected end to end, that is, the liquid storage tank 113 has a "bow" shaped structure. One end of one of the sub-reservoirs 1131 adjacent to the drainage channel 114 is provided with a second connection groove (not shown) that connects the drainage channel 114 with the reservoir 113.

It is understood that the atomizing top base 115 and the atomizing base 116 may be integrally formed or detachably connected; when the atomizing top base 115 and the atomizing base 116 are integrally formed, the corresponding air exchange tank 112, the drainage tank 114 and the liquid storage tank 113 can be formed and communicated with each other through one processing flow.

Referring to fig. 9, fig. 9 is a schematic view illustrating an assembly structure of the atomizing base and the first sealing member in fig. 2 b.

Referring to fig. 2 and 9, the atomizing assembly 1 further includes a first seal 18; the first sealing member 18 includes a top wall and a side wall, the top wall of the first sealing member 18 is disposed on the top surface of the atomizing top base 115, and the side wall of the first sealing member 18 is disposed on the outer side surface of the atomizing top base 115. That is, the top wall of the first sealing member 18 is disposed on the top surface of the atomizing base 11, and the side wall of the first sealing member 18 is disposed on the outer side surface of the atomizing base 11. And the side wall of the first sealing member 18 covers the air exchange groove 112 provided on the outer surface of the atomizing top base 115; that is, the side wall of the first sealing member 18 cooperates with the scavenging groove 112 to form a scavenging passage (not shown). The gap between the end surface of the side wall of the first sealing element 18 close to the atomizing base 116 and the top surface of the atomizing base 116 is more than or equal to 0.1mm and less than or equal to 0.3 mm; preferably, 0.25 mm. It will be appreciated that the gap between the first sealing member 18 and the top surface of the atomizing base 116 may better ensure the ventilation of the ventilation channel, which may form a ventilation channel around the atomizing base 11, to avoid poor ventilation caused by liquid leakage blockage.

Referring to fig. 2 and 9, the recess 1161 on the atomizing base 116 includes a first sidewall and a second sidewall disposed opposite to each other, and a third sidewall and a fourth sidewall connecting the first sidewall and the second sidewall; the blind holes 162 are disposed on the first sidewall and the second sidewall of the recess 1161, and notches (not shown) are disposed on the third sidewall and the fourth sidewall of the recess 1161. The surface of the atomizing top base 115 close to the atomizing base 116 is provided with a groove (not shown), and the groove on the atomizing top base 115 is matched with the groove 1161 to form the installation cavity 110; the groove on the atomizing top base 115 comprises a first side wall and a second side wall which are oppositely arranged, and a third side wall and a fourth side wall which are connected with the first side wall and the second side wall; the blind holes 163 are disposed on the first sidewall and the second sidewall of the groove on the atomizing top base 115, and the third sidewall and the fourth sidewall of the groove on the atomizing top base 115 are both provided with notches (not shown). The notches on the third and fourth sidewalls of the groove on the atomizing top base 115 and the notches on the third and fourth sidewalls of the groove 1161 are correspondingly disposed, and the notches on the atomizing top base 115 and the atomizing base 116 cooperate with the housing 10 to form the airflow channel 19. That is, the atomizing core 12 is partially exposed to the air flow channel 19 through the notch on the atomizing top seat 115 and the notch on the atomizing base 116, so that the aerosol atomized by the atomizing core 12 flows through the two sides of the atomizing core 12 into the air outlet channel 14.

In order to further prevent leakage from spreading to the air flow channel 19 along the gap between the atomizing base 11 and the housing 10 and then into the air outlet channel 14 to cause suction leakage, vertical ribs 181 are provided on the side wall of the first sealing element 18 and/or ribs 1152 are provided on the atomizing top base 115. That is, the vertical ribs 181 provided on the side wall of the first seal member 18 serve to prevent leakage from entering the airflow passage 19; a rib 1152 provided on the atomizing top 115 serves to prevent leakage into the air flow passage 19. Meanwhile, the convex ribs 1152 can support the shell 10, the rigidity of the shell 10 is improved, the structural rigidity of an ultrathin product is prevented from being weakened, and user experience is improved.

The two sides of the first sealing element 18 corresponding to the airflow channel 19 are provided with vertical convex ribs 181, and the vertical convex ribs 181 extend along the height direction of the side wall of the first sealing element 18; the included angle between the extending direction of the vertical convex rib 181 and the central axis of the atomization assembly 1 is smaller than 90 degrees, namely the extending direction of the vertical convex rib 181 is not parallel to the thickness direction and the width direction of the atomization assembly 1; preferably, the extending direction of the vertical rib 181 is parallel to the central axis direction of the atomizing assembly 1, that is, the included angle therebetween is 0 degree. And the vertical ribs 181 are in contact with the housing 10; preferably, the vertical rib 181 extends along the height direction of the side wall of the first seal 18 by the same length as the height of the side wall of the first seal 18. The height direction of the side wall of the first sealing member 18 is the same as the length direction of the atomizing assembly 1. In a specific embodiment, since the partial channels of the airflow channel 19 connecting the air outlet channel 14 and the atomizing chamber 111 are two channels located at two sides of the atomizing assembly 1 in the thickness direction, the vertical ribs 181 need to be respectively disposed at two sides of the two channels, that is, there are 4 vertical ribs 181 in this embodiment.

The atomizing top seat 115 is provided with convex ribs 1152 corresponding to both sides of the air flow channel 19, and the convex ribs 1152 extend along the height direction of the atomizing top seat 115; preferably, the ribs 1152 extend along the edges of the indentation in the atomizing tip 115; more preferably, ribs 1152 are provided along opposite edges of the indentation in the atomizing tip 115. It can be understood that the extending direction of the ribs 1152 forms an angle smaller than 90 degrees with the central axis direction of the atomizing assembly 1, that is, the extending direction of the ribs 1152 is not parallel to the thickness and width directions of the atomizing assembly 1. Preferably, the extending direction of the convex ribs 1152 forms an angle of more than 0 degree and less than 90 degrees with the length direction of the atomizing assembly 1; so that the ribs 1152 can support the housing 10 in the length and width directions of the atomizing assembly 1 when contacting the housing 10, thereby improving the overall strength and rigidity of the housing 10 or the atomizing assembly 1. The gap between the ribs 1152 and the housing 10 is 0-0.03 mm. The height direction of the atomizing top 115 is the same as the length direction of the atomizing assembly 1.

In a specific embodiment, since the partial channels of the air flow channel 19 connecting the air outlet channel 14 and the atomizing chamber 111 are two channels located at two sides of the atomizing assembly 1 in the thickness direction, the ribs 1152 need to be respectively disposed at two sides of the two channels, that is, there are 4 ribs 1152 in the embodiment.

Referring to fig. 9, the projections of the ribs 1152 and the vertical ribs 181 along the width direction of the atomizing assembly 1 are at least partially overlapped, so that the combined sealing of the air flow channel 19 is realized, the liquid between the atomizing base 11 and the housing 10 is prevented from entering the air flow channel 19 as much as possible, and the suction leakage is prevented to the maximum extent.

In the design of the atomizing assembly 1, a gap of 0.1mm-0.2mm is usually provided between the atomizing base 11 and the housing 10 for the convenience of product assembly, but the hidden trouble caused by this is that the condensate remaining on the outer wall of the atomizing base 11 is sucked into the air outlet channel 14 during the suction process, resulting in suction leakage. Through all being provided with vertical protruding muscle 181 in first sealing member 18 both sides corresponding to airflow channel 19, first sealing member 18 is sealed when realizing between the internal surface of atomizing footstock 115 and casing 10 for the unable airflow channel 19 that gets into of liquid of atomizing footstock 115 surface, and then gets into air outlet channel 14, prevents the risk of suction weeping. Through all being provided with the spur 1152 at the atomizing footstock 115 both sides that correspond to air current channel 19, and set up the clearance between spur 1152 and casing 10 to 0-0.03mm (this clearance is for the convenience of assembly), make the spur 1152 can further effectively prevent the liquid between atomizing seat 11 and casing 10 to get into air current channel 19, and then get into outlet channel 14, the spur 1152 can play the supporting role to casing 10 simultaneously, can alleviate the deformation phenomenon that presses casing 10 to cause, be favorable to improving the structural rigidity of ultra-thin product.

Referring to fig. 10-12, fig. 10 is an enlarged view of a portion of fig. 2b, fig. 11 is a view illustrating the first sealing member and the housing of fig. 10, and fig. 12 is a cross-sectional view of the atomizing assembly of fig. 10 taken along the direction C-C.

Generally, the entire atomizing assembly 1 is flat; that is, the cross section of the atomizing assembly 1 perpendicular to the length direction thereof is a cross section thereof, and the cross section is approximately elliptical. Therefore, similar to an ellipse, a line segment defining the longest connecting line of two vertexes in the cross section of the atomizing assembly 1 is a major axis and a connecting line of two vertexes closer to each other is called a minor axis, and accordingly, the major axis and the minor axis of the first seal 18 and the third seal 1162 can be obtained.

At least one first annular protrusion 182 is disposed on the sidewall of the first sealing member 18, and the first sealing member 18 is in interference fit with the housing 10 through the first annular protrusion 182. The first annular projection 182 is shaped to match the cross-sectional shape of the sidewall of the first seal member 18. The interference between the apex of the major axis of the first annular projection 182 and the housing 10 is a first value, the interference between the apex of the minor axis of the first annular projection 182 and the housing 10 is a second value, and the first value is smaller than the second value. That is, the interference between the major axis apex of the first annular projection 182 and the case 10 is smaller than the interference between the minor axis apex of the first annular projection 182 and the case 10. Further, the difference between the second value and the first value is greater than 0 and equal to or less than 0.05 mm. The difference between the first and second values may be selected as required to prevent leakage of aerosol-generating substrate from the reservoir 13.

In the present embodiment, the cross-sectional shape of the housing 10 is an ellipse, and the cross-sectional shape of the corresponding first seal member 18 is also an ellipse; referring to fig. 11 and 12, a region a is a major axis vertex of the sidewall of the first seal 18, and a region B is a minor axis vertex of the sidewall of the first seal 18. It is understood that, in order to make the electronic atomizer light and thin, even if the cross-sectional shape of the housing 10 is not an ellipse, the cross-sectional shape of the housing 10 has a major axis and a minor axis, and the cross-sectional shape of the first sealing member 18 has a major axis and a minor axis, respectively, it is sufficient that the interference between the apex of the major axis of the first annular projection 182 and the housing 10 is smaller than the interference between the apex of the minor axis of the first annular projection 182 and the housing 10.

Since the strength of the case 10 in the thickness direction in the ultra-thin electronic atomizer is weaker than that of a conventional product, the first sealing member 18, which is designed to be sealed inside, is more easily deformed by force, thereby risking the deterioration of the sealing performance of the reservoir 13. By making the interference between the long axis vertex of the first annular protrusion 182 and the casing 10 smaller than the interference between the short axis vertex of the first annular protrusion 182 and the casing 10, the force applied to the casing 10 at the long axis vertex corresponding to the first annular protrusion 182 is smaller than the force applied to the casing 10 at the short axis vertex corresponding to the first annular protrusion 182; namely, the width direction single-side interference is the same as that of a conventional product, and the thickness direction single-side interference is larger than that of the width direction single-side interference, so that the weakening of sealing caused by the deformation of the shell 10 is compensated, the overall sealing performance of the product is ensured, and the leakage of aerosol generating substrates caused by the sealing failure of the liquid storage cavity 13 is avoided.

Further, from the apex of the major axis of the first annular projection 182 to the apex of the minor axis of the first annular projection 182, the interference between the first annular projection 182 and the housing 10 gradually increases along the circumferential direction of the first annular projection 182. That is, the stress from the top of the long axis of the housing 10 corresponding to the first annular protrusion 182 to the top of the short axis of the housing 10 corresponding to the first annular protrusion 182 gradually increases along the circumferential direction of the housing 10, so that the stress at the top of the long axis of the housing 10 corresponding to the first annular protrusion 182 is the smallest, and the stress at the top of the short axis of the housing 10 corresponding to the first annular protrusion 182 is the largest, thereby compensating for the weakening of the seal caused by the deformation of the housing 10, ensuring the sealing performance of the product as a whole, and avoiding the leakage of the aerosol-generating substrate caused by the sealing failure of the liquid storage chamber 13. In one embodiment, the first annular protrusion 182 has two opposite major axis vertices and two opposite minor axis vertices, and the interference between the first annular protrusion 182 and the housing 10 gradually increases along the circumferential direction of the first annular protrusion 182 from any one of the major axis vertices to one of the minor axis vertices.

In one embodiment, the sidewall of the first seal member 18 is in contact with the inner wall surface of the housing 10, and the interference fit with the housing 10 is achieved by providing a first annular protrusion 182 on the sidewall of the first seal member 18; by adjusting the projection height of the first annular projection 182, adjustment of the interference between the first seal member 18 and the housing 10 is achieved.

Referring to fig. 9, the vertical rib 181 extends in the height direction of the side wall of the first seal member 18, and the first annular projection 182 extends in the circumferential direction of the side wall of the first seal member 18. In one embodiment, two first annular protrusions 182 are disposed on the sidewall of the first seal 18, and the two first annular protrusions 182 are spaced apart; the one end of vertical protruding muscle 181 and two first annular protruding 182 in keep away from the first annular protruding 182 butt of stock solution chamber 13, the other end of vertical protruding muscle 181 with to the direction extension of keeping away from first annular protruding 182. The two first annular protrusions 182 and the housing 10 both satisfy the above interference fit relationship.

A third sealing member 1162 is disposed at an end of the atomizing base 116 away from the reservoir 13, and the third sealing member 1162 is disposed along a circumferential direction of the atomizing base 116 and contacts the housing 10 to seal between the atomizing base 116 and the housing 10. The interference between the major axis apex of the third seal 1162 and the housing 10 is less than the interference between the minor axis apex of the third seal 1162 and the housing 10. The specific arrangement of the interference between the third sealing element 1162 and the housing 10 is the same as the arrangement of the interference between the first sealing element 18 and the housing 10, and is not described again.

By making the interference between the vertex of the long axis of the third sealing element 1162 and the housing 10 smaller than the interference between the vertex of the short axis of the third sealing element 1162 and the housing 10, the weakening of the seal caused by the deformation of the housing 10 is further compensated, and the overall sealing performance of the product is ensured.

With continued reference to fig. 10, a vent hole 117 is formed at one end of the atomizing base 11 close to the air outlet channel 14; that is, the atomizing top base 115 is provided with the vent hole 117, and the two lower liquid passages 1151 are located on both sides of the vent hole 117. The vent hole 117 is communicated with the air outlet channel 14, and the vent hole 117 is communicated with the atomizing chamber 111, so that the atomized aerosol of the atomizing core 12 flows out of the air outlet channel 14. The end part of the air outlet channel 14 is embedded in the vent hole 117; part of the inner surface of the vent hole 117 is attached to part of the outer surface of the outlet channel 14, and the other part of the inner surface of the vent hole 117 is provided with a liquid guiding bone 1171, that is, the inner surface of the part of the vent hole 117 not provided with the outlet channel 14 is provided with the liquid guiding bone 1171. The side of the liquid guiding bone 1171 far away from the inner surface of the vent hole 117 forms a tip, and the distance between the tip and the inner surface of the vent hole 117 is a third value H, and the third value H is larger than the wall thickness of the air outlet channel 14. In a specific embodiment, the third value H is 0.3-0.7mm greater than the wall thickness of the outlet channel 14; preferably, 0.5 mm.

Specifically, an included angle alpha of 70-80 degrees is formed between the top surface of the liquid guiding bone 1171 and the side surface of the liquid guiding bone 1171 to form a tip; preferably 75 deg.. The top surface of the liquid guiding bone 1171 is the end surface of the liquid guiding bone 1171 close to the air outlet channel 14; the side surface of the liquid guiding bone 1171 is the end surface of the liquid guiding bone 1171 far away from the inner surface of the vent hole 117, and the end surface is connected with the end surface of the liquid guiding bone 1171 near the air outlet channel 14. The top surface of the liquid guiding bone 1171 is abutted against the end surface of the air outlet channel 14; that is, the end surface of the liquid guiding rib 1171 close to the gas outlet channel 14 abuts against the end surface of the gas outlet channel 14.

In one embodiment, two liquid guiding bones 1171 are symmetrically arranged on the inner surface of the vent hole 117, and the tips of the two liquid guiding bones 1171 are arranged at intervals. In one embodiment, the longitudinal cross-section of the bone 1171 is triangular.

Because the condensed liquid in the ultrathin electronic atomization device is formed quickly, the condensed liquid is easy to accumulate into a liquid column in the air outlet channel 14, and suction leakage is caused. In the embodiment, the whole section of the air outlet channel 14 is smooth without corners, so that the condensate can slide down conveniently, and the condensate is less accumulated; meanwhile, two liquid guiding bones 1171 are symmetrically arranged on the inner surface of the vent hole 117, the third value H of the distance between the tip of the liquid guiding bones 1171 and the inner surface of the vent hole 117 is larger than the wall thickness of the air outlet channel 14, condensate in the air outlet channel 14 can spread and flow along the surfaces of the liquid guiding bones 1171 under the action of surface tension after contacting the liquid guiding bones 1171, finally flows back to the atomizing core 12 to be atomized for the second time, and accumulated liquid in the air outlet channel 14 is eliminated, so that the phenomenon of liquid leakage during suction is avoided; and the top surface of the liquid guiding bone 1171 and the side surface of the liquid guiding bone 1171 form a tip at an included angle, and the tips of the two liquid guiding bones 1171 are arranged at intervals, namely, a gap exists between the two liquid guiding bones 1171, so that aerosol mixing on two sides of the liquid guiding bones 1171 is facilitated, and the suction taste is improved.
