Description

Atomizing device and device for storing solution

Technical Field

The present disclosure relates generally to nebulization devices (nebulization devices) and devices for storing solutions, and more particularly to electronic devices for providing inhalable aerosols (aerosol).

background

An electronic cigarette is an electronic product that heats and atomizes an nebulizable solution and generates an aerosol for a user to inhale. In recent years, various electronic cigarette products have been produced by large manufacturers. Generally, an electronic cigarette product includes a housing, an oil chamber, an atomizing chamber, a heating element, an air inlet, an air flow channel, an air outlet, a power supply device, a sensing device and a control device. The oil storage chamber is used for storing the nebulizable solution, and the heating component is used for heating and nebulizing the nebulizable solution and generating aerosol. The air inlet and the aerosolizing chamber communicate with one another to provide air to the heating assembly when a user inhales. The aerosol generated by the heating element is first generated in the aerosolizing chamber and then inhaled by the user via the air flow passage and the air outlet. The power supply device provides the electric power required by the heating component, and the control device controls the heating time of the heating component according to the user inspiration action detected by the sensing device. The shell covers the above components.

Existing electronic cigarette products suffer from various drawbacks that may result from poor design of the relative positions of the various components. For example, common electronic cigarette products design the heating element, the airflow channel, and the air outlet to be vertically aligned with one another. Because the airflow channel has a certain length, the aerosol is cooled when passing through the airflow channel, and condensed liquid is formed and attached to the wall of the airflow channel. With this design, when the remaining condensed liquid reaches a certain volume, the condensed liquid is easily directed into the mouth of the user's mouth when inhaling, causing a choking negative experience.

Furthermore, existing electronic cigarette products do not allow for the prevention of condensate backflow. When the electronic cigarette product is placed in an inclined or inverted position, the condensed liquid remaining in the atomizing chamber or the airflow passage may overflow from the air inlet or the air outlet. Spilled condensate may cause damage to electrical components (e.g., sensing and control devices) within the electronic smoking product or cause a poor user experience.

Furthermore, existing electronic cigarette products do not take into account the pressure balance of the oil reservoir. In existing electronic cigarette products, the oil reservoir is typically designed to be completely sealed to prevent the aerosolizable solution from escaping. With the continuous use of the electronic cigarette product by the user, the nebulizable solution in the oil storage chamber is continuously consumed and reduced, so that the pressure in the oil storage chamber is reduced to form negative pressure. The negative pressure makes the solution that can atomize in the oil storage chamber be difficult to evenly flow to heating element on, makes heating element not evenly adsorb the solution that can atomize. At this time, when the temperature of the heating element rises, there is a high probability that the heating element will burn empty to generate scorched smell, which results in poor user experience.

in view of the above, the present disclosure provides an atomization device and a device for storing a solution, which can solve the above problems.

An atomization device is provided. The proposed atomising device comprises a cartridge. The cartridge has a housing, a heating assembly, and a heating assembly top cap. The heating component is provided with a groove, and the opening of the groove faces to the first direction. The heating assembly top cap has an inverted component having a first cavity with an opening facing a second direction, wherein the first direction is different from the second direction.

A device for storing a solution is presented. The proposed device for storing a solution comprises a housing, a heating assembly and a heating assembly top cover.

The heating element top cover 4 and the heating element base 8 may be removably coupled by a snap-fit.

The heating member 6 includes a conductive member 6 p. The atomizer 100 may provide power to the heater assembly 6 via the conductive assembly 6p to raise the temperature of the heater assembly 6.

the sensor activation tube 7 may be a hollow tube. The sensor activation tube 7 may be disposed at one side of the heating assembly base 8. The sensor activation tube 7 may be disposed on the side of the heating assembly base 8 near the intake passage.

The conductive contact 9 is brought into contact with the conductive member 6p of the heating member 6 through the through hole 8h1 in the heating member base 8. The conductive contact 9 may be in physical contact with the conductive member 6 p. The conductive contact 9 and the conductive member 6p may be electrically connected to each other.

A base O-ring (O-ring)10 may be secured within a groove 8g of the heating element base 8. The base O-ring 10 and the heating element base 8 are coupled to each other and then nested within the cartridge metal base 11. The cartridge metal base 11 may be wrapped around the base O-ring 10. The cartridge metal base 11 may encase at least a portion of the heating element base 8.

One end of the conductive contact 9 passes through the through hole 8h1 on the heating element base 8, and the other end of the conductive contact 9 can be exposed through the through hole on the cartridge metal base 11.

As shown in fig. 3, the cartridge 100A includes an oil storage compartment 30, an air inlet channel 31, an air outlet channel 32, a partition structure 33, a partition structure 34, an air inlet hole 31h, and an air outlet hole 32 h. In some embodiments, the inlet channel 31 and the outlet channel 32 may be located inside the cartridge housing 3. In some embodiments, the inlet channel 31 and the outlet channel 32 may be defined by the internal structure of the cartridge housing 3. As shown in fig. 3, the cartridge housing 3 and the compartment structure 33 define an air intake passage 31. The cartridge housing 3 and the compartment structure 34 define the outlet channel 32. The intake passage 31 is in fluid communication with the intake holes 31 h. The outlet passage 32 is in fluid communication with the outlet aperture 32 h.

In some embodiments, the length of the compartment structure 33 is different from the length of the compartment structure 34. In certain embodiments, the length of the compartment structure 33 is greater than the length of the compartment structure 34. In some embodiments, the maximum length 3L1 of the compartment structure 33 from the exit aperture 32h is greater than the maximum length 3L2 of the compartment structure 34 from the exit aperture 32 h. As shown in fig. 3, the difference between length 3L1 and length 3L2 is length 3 LD. The compartment structure 33 extends on one side (the left side as viewed in fig. 3) of the heating element top cover 4 and the heating element base 8. The compartment structure 33 extends and covers one side of the heating element top cover 4 and the heating element base 8.

The liquid in the oil reservoir 8t can move toward the air intake passage 31 through the gap between the heating element top cover 4 and the heating element base 8 by capillary phenomenon (see fig. 5). The partition structure 33 covering the heating element top cover 4 and the heating element base 8 prevents the liquid in the oil reservoir 8t from moving toward the air intake passage 31. The elongated partition structure 33 can block the liquid in the oil reservoir 8t from leaking to the intake passage 31.

In some embodiments, the diameter of the inlet channel 31 may be the same as the diameter of the outlet channel 32. In some embodiments, the diameter of the inlet channel 31 may be different from the diameter of the outlet channel 32. In some embodiments, the diameter of the inlet channel 31 may be smaller than the diameter of the outlet channel 32. The smaller diameter of the inlet channel 31 makes it easier for the sensor activation tube 7 to generate a negative pressure. The smaller diameter of the inlet channel 31 allows the sensor in the main body 100B to detect the inhalation of the user more easily. In some embodiments, a blocking member may be further disposed within the intake passage 31. As shown in fig. 3, a blocking member 35 is contained in the intake passage 31.

FIG. 4A illustrates a cross-sectional view of a barrier assembly 35 according to some embodiments of the invention. FIG. 4B illustrates a top view of a barrier assembly 35 according to some embodiments of the invention.

As shown in fig. 4A and 4B, the blocking element 35 has a first surface 35S1 and a second surface 35S 2. The barrier member 35 has an opening 35O1 on the first surface 35S 1. The barrier member 35 has an opening 35O2 on the second surface 35S 2. Opening 35O1 extends to opening 35O2 to form channel 35 c. The channel 35c may be regarded as a part of the intake passage 31. In certain embodiments, the diameter of opening 35O1 and opening 35O2 may be the same. In certain embodiments, the diameter of opening 35O1 and opening 35O2 may be different. As shown in fig. 4A, diameter 35L1 of opening 35O1 may be smaller than diameter 35L2 of opening 35O 2.

The different opening diameters of the blocking member 35 prevent the user from making a squeak while inhaling. The different opening diameters of the blocking member 35 prevent the squeak sound from causing erroneous determination of the sensor in the main body 100B. The diameter 35L1 of the opening 35O1 being smaller than the diameter 35L2 of the opening 35O2 prevents the user from making a sharp sound when inhaling. The diameter 35L1 of the opening 35O1 being smaller than the diameter 35L2 of the opening 35O2 prevents the squeak from causing erroneous sensor determinations in the body 100B.

In certain embodiments, the diameter of opening 35O1 is in the range of 0.4mm to 0.5 mm. In certain embodiments, the diameter of opening 35O1 is in the range of 0.5mm to 0.6 mm. In certain embodiments, the diameter of opening 35O1 is in the range of 0.6mm to 0.7 mm. In certain embodiments, the diameter of opening 35O1 is in the range of 0.7mm to 0.8 mm. In certain embodiments, the diameter of opening 35O1 is in the range of 0.8mm to 0.9 mm. In certain embodiments, the diameter of opening 35O1 is 0.69 mm.

In certain embodiments, the diameter of opening 35O2 is in the range of 0.4mm to 0.6 mm. In certain embodiments, the diameter of opening 35O2 is in the range of 0.6mm to 0.8 mm. In certain embodiments, the diameter of opening 35O2 is in the range of 0.8mm to 1.0 mm. In certain embodiments, the diameter of opening 35O2 is in the range of 1.0mm to 1.2 mm. In certain embodiments, the diameter of opening 35O2 is in the range of 1.2mm to 1.4 mm. In certain embodiments, the diameter of opening 35O2 is 0.9 mm.

The barrier member 35 may have a thickness 35T1 on the first surface 35S 1. The barrier member 35 may have a thickness 35T2 on the second surface 35S 2. Thickness 35T1 is greater than thickness 35T 2. The thickness 35T2 creates a height drop within the intake passage 31. Since the liquid or soot accumulated in the oil reservoir 8t has viscosity, even if the liquid or soot in the oil reservoir 8t leaks into the cavity 8c2, the height difference prevents the liquid or soot from entering the air intake passage 31 through the passage 35 c. The height difference can prevent liquid or tobacco tar from overflowing from the air inlet hole 31 h.

In certain embodiments, the barrier assembly 35 may be made of silicone. In some embodiments, the blocking member 35 may be a silicone ring. In some embodiments, the barrier assembly 35 may be made of the same material as the cartridge housing 3. In some embodiments, the barrier assembly 35 may be made of a different material than the cartridge housing 3. In certain embodiments, the barrier assembly 35 and the cartridge housing 3 may be two separate components. In certain embodiments, the barrier assembly 35 may be integrally formed with the cartridge housing 3.

As shown in fig. 5, the cartridge 500A includes an oil storage compartment 50, an air inlet channel 51, an air outlet channel 52, a partition structure 53, a partition structure 54, an air inlet hole 51h, and an air outlet hole 52 h. As shown in FIG. 5, the maximum length of the compartment structure 53 from the exit aperture 52h is the same as the maximum length of the compartment structure 54 from the exit aperture 32h (length 5L shown in FIG. 5). No blocking member is provided in the intake passage 51. Referring to fig. 3 and 5, the length 5L of the compartment structure 53 is shorter than the length 3L1 of the compartment structure 33 in fig. 3, and no blocking member is disposed in the air inlet 51.

As shown in fig. 5, the compartment structure 53 does not completely cover one side of the heating element top cover 4 and the heating element base 8. The compartment structure 53 does not cover the gap between the heating element top cover 4 and the heating element base 8.

In the cartridge 500A shown in fig. 5, the condensed liquid may move from the oil reservoir 8t in the direction shown by the arrow 5A toward the intake passage 51 and the intake hole 51h due to capillary phenomenon. The condensed liquid overflowing from the air inlet hole 51h may cause damage to electrical components (e.g., sensing and control devices) within the electronic cigarette product or cause a poor experience for the user. However, the design of the length of the compartment structure of the cartridge 300A shown in FIG. 3 and the design of the blocking member in the air intake passage solve the above problems.

Fig. 6A illustrates a perspective view of a heating assembly top cover 4, according to some embodiments of the present disclosure. Fig. 6B illustrates a cross-sectional view of a heating assembly top cover 4, according to some embodiments of the present disclosure. Fig. 6C illustrates a bottom schematic view of the heating assembly top cover 4, according to some embodiments of the present disclosure.

Referring to fig. 6A, 6B and 6C, the heating element top cover 4 has a top surface 4u and a bottom surface 4B. The heating unit top cover 4 has an opening 4h1 and an opening 4h2 on the top surface 4 u. The heating unit top cover 4 has an opening 4h3 and an opening 4h4 on the bottom surface 4 b. The opening 4h1 extends into the heating assembly top cover 4 and forms a channel (e.g., channel 4c1 shown in fig. 6B) that faces the opening 4h 3. The opening 4h2 extends into the heating assembly top cover 4 and forms a channel (e.g., channel 4c2 shown in fig. 6B) that faces the opening 4h 4. The nebulizable material (e.g. tobacco tar) stored in the reservoir 30 can pass from the opening 4h1 into the channel 4c1 and flow via the opening 4h3 into the recess 6c of the heating element 6. The nebulizable material (e.g. tobacco tar) stored in the reservoir 30 can pass from the opening 4h2 into the channel 4c2 and flow via the opening 4h4 into the recess 6c of the heating element 6.

In some embodiments, the oil inlet passages formed by the openings 4h1, 4c1 and 4h3 and the oil inlet passages formed by the openings 4h2, 4c2 and 4h4 may be substantially symmetrical to each other. In some embodiments, the oil inlet passages formed by opening 4h1, passage 4c1, and opening 4h3 are not symmetrical to the oil inlet passages formed by opening 4h2, passage 4c2, and opening 4h 4. In some embodiments, the heating assembly top cover 4 may have more openings. In certain embodiments, the heating assembly top cover 4 may have fewer openings. In some embodiments, the heating assembly top cover 4 may have more channels. In certain embodiments, the heating assembly top cover 4 may have fewer channels.

As shown in fig. 3 and 6B, the passage 4c1 has a surface 4s1 and a surface 4s 2. In certain embodiments, the angle between surface 4s1 and surface 4s2 of channel 4c1 is between 95 and 180 degrees. In certain embodiments, the angle between surface 4s1 and surface 4s2 of channel 4c1 is between 95 and 120 degrees. In certain embodiments, the angle between surface 4s1 and surface 4s2 of channel 4c1 is between 120 and 140 degrees. In certain embodiments, the angle between surface 4s1 and surface 4s2 of channel 4c1 is between 140 and 160 degrees. In certain embodiments, the angle between surface 4s1 and surface 4s2 of channel 4c1 is between 160 and 180 degrees. The angle between the surface 4s1 and the surface 4s2 of the channel 4c1 is configured such that the channel 4c1 has a turn. The angle between the surface 4s1 and the surface 4s2 of the passage 4c1 allows the liquid smoke in the oil reservoir 30 to enter the groove 6c of the heating element 6 more smoothly. The turn in the passage 4c1 allows the soot in the reservoir 30 to more smoothly enter the groove 6c of the heating element 6.

The groove 6c of the heating element 6 has a surface 6s1, a surface 6s2, and a surface 6s 3. The angle between the surface 6s1 and the surface 6s2 of the groove 6c is between 95 and 180 degrees. In certain embodiments, the angle between the surface 6s1 and the surface 6s2 of the groove 6c is between 95 to 120 degrees. In certain embodiments, the angle between the surface 6s1 and the surface 6s2 of the groove 6c is between 120 and 140 degrees. In certain embodiments, the angle between the surface 6s1 and the surface 6s2 of the groove 6c is between 140 to 160 degrees. In certain embodiments, the angle between the surface 6s1 and the surface 6s2 of the groove 6c is between 160 and 180 degrees.

The angle between the surface 6s3 and the surface 6s2 of the groove 6c is between 95 and 180 degrees. In certain embodiments, the angle between the surface 6s3 and the surface 6s2 of the groove 6c is between 95 to 120 degrees. In certain embodiments, the angle between the surface 6s3 and the surface 6s2 of the groove 6c is between 120 and 140 degrees. In certain embodiments, the angle between the surface 6s3 and the surface 6s2 of the groove 6c is between 140 to 160 degrees. In certain embodiments, the angle between the surface 6s3 and the surface 6s2 of the groove 6c is between 160 and 180 degrees.

In certain embodiments, the angle between the surface 6s1 of the groove 6c and the surface 4s2 of the channel 4c1 is between 5 and 20 degrees. In certain embodiments, the angle between the surface 6s1 of the groove 6c and the surface 4s2 of the channel 4c1 is between 5 and 10 degrees. In certain embodiments, the angle between the surface 6s1 of the groove 6c and the surface 4s2 of the channel 4c1 is between 10 and 15 degrees. In certain embodiments, the angle between the surface 6s1 of the groove 6c and the surface 4s2 of the channel 4c1 is between 15 and 20 degrees.

In certain embodiments, the angle between the surface 6s3 of the groove 6c and the surface 4s3 of the channel 4c2 is between 5 and 20 degrees.

In certain embodiments, the angle between the surface 6s3 of the groove 6c and the surface 4s3 of the channel 4c2 is between 15 and 20 degrees.

The angular disposition of the passages 4c1 and 4c2 into the groove 6c of the heating element 6 is designed to facilitate the flow of the soot into the groove 6c and to prevent the soot entering the groove 6c of the heating element 6 from flowing back to the reservoir 30, thereby maintaining the quality of the soot in the reservoir 30.

Referring to fig. 6B, the heating assembly top cover 4 has an inverted buckle assembly 4i between the channel 4c1 and the channel 4c 2. The toggle assembly 4i includes a segment 4i1, a segment 4i2, a segment 4i3, and a segment 4i 4. The section 4i1 extends in a direction. The section 4i2 extends in a direction. The section 4i3 extends in a direction. In certain embodiments, the direction of extension of section 4i1 and the direction of extension of section 4i2 may be parallel. In certain embodiments, the direction of extension of section 4i1 and the direction of extension of section 4i3 may be parallel. In certain embodiments, the direction of extension of section 4i2 and the direction of extension of section 4i3 may be parallel. In certain embodiments, the direction of extension of section 4i1 and the direction of extension of section 4i2 may not be parallel. In certain embodiments, the direction of extension of section 4i1 and the direction of extension of section 4i3 may not be parallel. In certain embodiments, the direction of extension of section 4i2 and the direction of extension of section 4i3 may not be parallel.

Segment 4i1, segment 4i2, and segment 4i3 may be connected to each other via segment 4i 4. In some embodiments, the extension direction (e.g., vertical direction in fig. 6B) of the segment 4i1, the segment 4i2 and the segment 4i3 is substantially perpendicular to the extension direction (e.g., horizontal direction in fig. 6B) of the segment 4i 4. In some embodiments, the extension direction of the segment 4i1, the segment 4i2, and the segment 4i3 is not perpendicular to the extension direction of the segment 4i 4. In some embodiments, the reversing component 4i may be composed of more sections. In certain embodiments, the undercut assembly 4i may be comprised of fewer sections.

As shown in FIG. 6B, the length of section 4i1 is less than the length of section 4i 2. The length of section 4i1 is less than the length of section 4i 3. In certain embodiments, the length of section 4i2 and the length of section 4i3 may be the same. In certain embodiments, the length of section 4i2 and the length of section 4i3 may be different. Since the length of the section 4i1 is short, the soot in the oil reservoir 30 is liable to flow into the groove 6c of the heating element 6 after passing through the turning point of the passage 4c 1.

Section 4i1, section 4i2, and section 4i4 form cavity 41. Section 4i2, section 4i3, and section 4i4 form cavity 42. The cavity 41 has an opening 41 v. The cavity 42 has an opening 42 v. The openings of the cavities 41 and 42 face the direction of the recess 6c of the heating element 6 (vertically downward in fig. 6B). The openings of the cavities 41 and 42 face in the opposite direction to the openings of the recess 6c of the heating element 6. The cavity 41 is in fluid communication with the groove 6c of the heating assembly 6 via an opening 41 v. The cavity 42 is in fluid communication with the recess 6c of the heating assembly 6 via an opening 42 v.

In some embodiments, the undercut assembly 4i may have additional cavities beyond the cavity 41 and the cavity 42. In some embodiments, the undercut assembly 4i may have a single cavity.

During continued use of the atomizing device 100, the atomizing material in the reservoir 30 is continuously consumed to generate bubbles in the reservoir 30. In certain embodiments, the nebulizable material (e.g., tobacco tar) may be in direct contact with the heating assembly 6 via the inner walls of the recess 6 c. During heating of the atomizing device, bubbles may also be generated in the heating assembly 6.

Since the inverted component 4i has the cavity 41 and the cavity 42, a part of the bubbles can be gathered or accumulated in the cavity 41 and the cavity 42, thereby dispersing the entire bubble volume of the oil storage chamber 30. Reducing the volume of the bubble in the reserve tank 30 can avoid the bubble from blocking the channel 4c1 or the channel 4c 2. Reducing the volume of the bubbles in the reservoir 30 avoids the problem of inconsistent oil feed. Accordingly, the nebulizable material (e.g., tobacco tar) in the reservoir 30 can be made to flow uniformly onto the heating element, and the heating element can be made to adsorb the nebulizable material (e.g., tobacco tar) uniformly.

Fig. 7B illustrates a schematic view of a sidewall of a heating assembly seal according to some embodiments of the invention. Figure 7C illustrates a partial cross-sectional view of a cartridge according to some embodiments of the invention. Fig. 7D illustrates a side wall schematic of a heating assembly seal according to some embodiments of the invention.

As shown in fig. 7A, 7B, and 7C, the heating element seal 5 has a top 501, a bottom 503, and a sidewall 505 extending between the top 501 and the bottom 503. The side wall 505 has a groove 5g 1. The top 501 of the heating assembly seal 5 has a groove 5g 2. The bottom 503 of the heating assembly seal 5 has a groove 5g 3.

Sidewall 505 comprises a partition 5p, which partition 5p comprises section 5p1 and section 5p2, and one end of section 5p1 is directly connected to one end of section 5p 2. The other end of the segment 5p1 forms a gap 5v1 with one side 5s1 of the groove 5g 1. The other end of the section 5p2 forms a gap 5v2 with the other side 5s2 of the groove 5g 1. In certain embodiments, the angle θ between section 5p1 and section 5p2₁Between 90 and 180 degrees. In certain embodiments, the angle θ between section 5p1 and section 5p2₁Between 90 and 120 degrees. In certain embodiments, the angle θ between section 5p1 and section 5p2₁Between 120 and 150 degrees. In some embodiments, segment 5p1 and segment 5p2Angle theta therebetween₁Between 150 and 180 degrees. In some embodiments, the segments 5p1 and 5p2 form a V-shape with the opening facing upward (e.g., the vertical upward direction shown in FIG. 7B).

The sidewall 505 of the heating assembly seal 5 further comprises a partition 5 q. The second divider 5q includes a section 5q1 and a section 5q 2. Gap 5v3 is formed between section 5q1 and section 5q 2. Segment 5q1 and segment 5q2 have an angle θ therebetween₂. In certain embodiments, the angle θ between section 5q1 and section 5q2₂Angle θ between section 5p1 and section 5p2₁May be different. In certain embodiments, the angle θ between section 5q1 and section 5q2₂angle θ between section 5p1 and section 5p2₁May be the same. In some embodiments, the segments 5p1 and 5p2 form an inverted V-shape with the opening facing downward (e.g., the vertically downward direction shown in FIG. 7B).

When the heating element seal 5 is covered on the heating element 6, at least one cavity (or referred to as an air-permeable passage) is defined between the partition 5p, the partition 5q, the groove 5g1 and the heating element 6. In detail, the groove 5g3, the gap 5v3, the gap 5v1 and the groove 5g2 may define the air vent channel 5c1 (as shown in fig. 7D). The atomizing chamber 8c can be in fluid communication with a reservoir (such as reservoir 30 shown in fig. 3) via the vent passage 5c 1. The groove 5g3, gap 5v3, gap 5v2, and groove 5g2 may define an air-permeable channel 5c2 (as shown in fig. 7D). The atomizing chamber 8c can be in fluid communication with a reservoir (such as reservoir 30 shown in fig. 3) via the vent passage 5c 2.

As the user continues to use the aerosolization apparatus, the aerosolizable material within the reservoir 30 is continually consumed and reduced, causing the pressure within the reservoir 30 to gradually decrease. A negative pressure may be generated when the pressure in the storage chamber 30 becomes small. The reduced pressure in the reservoir 30 may make it difficult for the nebulizable material, for example tobacco tar, to flow via the channels 4c1 and 4c2 to the groove 6c of the heating element 6. When the grooves 6c do not completely adsorb the nebulizable material, the heating element 6 of high temperature may dry out and develop a scorched smell.

This problem is ameliorated by providing a vent passage in the side wall of the heating element seal 5. The vent passages formed in the side walls of the heating element seal 5 (flow direction as shown by the arrows in fig. 7D) may equalize the pressure within the reservoir 30.

Fig. 8B illustrates an enlarged schematic view of a sidewall of a heating assembly seal according to some embodiments of the invention. Fig. 8C illustrates a cross-sectional view of a heating assembly seal according to some embodiments of the invention.

As shown in fig. 8A, 8B and 8C, the heating element seal 5' has a top 801, a bottom 803 and a sidewall 805 extending between the top 801 and the bottom 803. The sidewall 805 includes a spacer 8p1 and a spacer 8p 2. One end of the spacer 8p1 is connected to the top 801 and the other end of the spacer 8p1 is connected to the bottom 803.

In certain embodiments, partitions 8p1 and 8p2 are substantially parallel to each other. In certain embodiments, partitions 8p1 and 8p2 may be non-parallel. In certain embodiments, the heating assembly seal 5' may include more partitions that are substantially parallel to each other. In certain embodiments, the heating assembly seal 5' may include more partitions that are not parallel to each other. In certain embodiments, the heating assembly seal 5' may include fewer partitions.

The side wall 805 of the heating assembly seal 5' has a groove 8g 1. The top 801 of the heating assembly seal 5' has a groove 8g2 and the bottom 803 has a groove 8g 3. Heating element seal 5' also includes groove 8g4 and groove 8g 5. The partition 8p1 is disposed between the groove 8g1 and the groove 8g 4. The partition 8p2 is disposed between the groove 8g1 and the groove 8g 5.

The partitions 8p1, 8p2, the grooves 8g 1-8 g5 and the heating element 6 define at least one cavity (or ventilation channel). In detail, the grooves 8g3, 8g1, 8g2, the partitions 8p1, 8p2 define a first ventilation channel. The groove 8g4, the partition 8p1 and the heating member 6 define therebetween a second air-permeable passage. The groove 8g5, the partition 8p2 and the heating element 6 define a third air-permeable passage therebetween. In certain embodiments, the cartridge may contain more ventilation channels. In certain embodiments, the cartridge may contain fewer ventilation channels. With the above arrangement, the atomizing chamber 8c can be brought into fluid communication with a reservoir (e.g., the reservoir 30 shown in fig. 3) via the gas-permeable passage, so that the pressure in the reservoir 30 can be equalized.

as shown in fig. 9, the heating element base 8 includes a supporting member 81 and a supporting member 82, and a storage tank 8t between the supporting member 81 and the supporting member 82. The storage tank 8t is used for storing condensed liquid or smoke oil. The support member 81 is disposed adjacent to the intake passage 31. The support member 82 is disposed adjacent to the air outlet passage 32. In some embodiments, the support member 81 and/or the support member 82 may have a snap portion. The heating assembly base 8 may be coupled to the heating assembly top cover 4 via a snap-fit portion. The heating assembly base 8 may be removably coupled with the heating assembly top cover 4 via a snap-fit portion. The heating element 6 is disposed between the heating element top cover 4 and the heating element base 8.

The support member 81 may have a surface 81s1 and a surface 81s 2. In certain embodiments, the surface 81s1 is not coplanar with the surface 81s 2. A stepped structure is formed between the surface 81s1 of the support member 81 and the surface 81s 2. There is a height difference between the surface 81s1 and the surface 81s 2. In certain embodiments, the difference in height between the surface 81s1 and the surface 81s2 is in the range of 0.2mm to 0.3 mm. In certain embodiments, the difference in height between the surface 81s1 and the surface 81s2 is in the range of 0.3mm to 0.4 mm. In certain embodiments, the difference in height between the surface 81s1 and the surface 81s2 is in the range of 0.4mm to 0.5 mm. In certain embodiments, the difference in height between the surface 81s1 and the surface 81s2 is in the range of 0.5mm to 0.6 mm. In certain embodiments, the difference in height between the surface 81s1 and the surface 81s2 is in the range of 0.6mm to 0.7 mm. In certain embodiments, the difference in height between the surface 81s1 and the surface 81s2 is 0.5 mm. The design of the stepped structure allows the soot to easily flow toward the surface 81s2 without easily staying on the surface 81s 1. The design of the height difference can reduce the probability of smoke oil passing through the through hole 81 h.

The support member 81 includes one or more through holes 81h extending through the support member 81 from the surface 81s 1. As shown in fig. 9, the support member 81 may have 6 through holes 81 h. The through hole 81h communicates the atomizing chamber 8c and the intake passage 31 with each other. The aperture area of the through-hole 81h is designed to allow gas to pass therethrough. The arrangement of the through holes 81h is designed to allow the gas to pass therethrough. In some embodiments, the support member 81 may include more through holes. In certain embodiments, the support member 81 may include fewer through holes.

The aperture area of the through hole 81h is designed to make the smoke not easily pass through. The arrangement of the through holes 81h is designed to make the smoke not easily pass through. In some embodiments, the diameter of each of the through holes 81h is in the range of 0.2mm to 0.3 mm. In some embodiments, the diameter of each of the through holes 81h is in the range of 0.3mm to 0.4 mm. In some embodiments, the diameter of each of the through holes 81h is in the range of 0.4mm to 0.5 mm. In some embodiments, the diameter of each of the through holes 81h is in the range of 0.5mm to 0.6 mm. In some embodiments, the diameter of each of the through holes 81h is in the range of 0.6mm to 0.7 mm. In some embodiments, each of the through holes 81h may have a diameter of 0.55 mm.

The support member 82 has a ramp structure 82r near the bottom of the heating element base 8. The ramp structure 82r may form a barrier to the reservoir 8 t. The slope 82r prevents the soot or liquid accumulated in the oil reservoir 8t from entering the air outlet passage 32 during the inhalation of the user. The stepped structure prevents the smoke or liquid accumulated in the oil reservoir 8t from entering the air outlet passage 32 during the inhalation of the user.

In some embodiments, an oil absorbent cotton (not shown) may be disposed at the bottom of the oil storage tank 8 t. The oil absorption cotton can absorb the tobacco oil or liquid accumulated in the oil storage tank 8 t. The smoke oil or liquid absorbed by the oil absorption cotton is not easy to flow in the oil storage tank 8 t.
