Description

Atomization device

Technical field

The present disclosure generally relates to vaporization devices, and in particular to electronic devices that provide inhalable aerosols.

Background technique

An electronic cigarette is an electronic product that heats and atomizes an atomizable solution and generates an aerosol for users to inhale. In recent years, major manufacturers have begun to produce all kinds of electronic cigarette products. Generally speaking, an electronic cigarette product includes a housing, an oil storage chamber, an atomization chamber, a heating component, 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 to store the atomizable solution, and the heating component is used to heat and atomize the atomizable solution and generate aerosol. The air inlet and the atomizing chamber communicate with each other, and provide air to the heating assembly when the user inhales. The aerosol generated by the heating element is first generated in the atomization chamber, and then inhaled by the user through the air flow channel and the air outlet. The power supply device provides the power required by the heating element, and the control device controls the heating time of the heating element according to the user's inhalation action detected by the sensing device. The outer shell covers the above-mentioned components.

The existing electronic cigarette products have different defects, which may be caused by poor design of the relative positions of different components. For example, common electronic cigarette products design the heating element, the air flow channel, and the air outlet to be aligned with each other in a vertical direction. Because the air flow channel has a certain length, when the aerosol passes through the air channel, it cools and forms a condensed liquid attached to the wall of the air channel. Under this design, when the residual condensed liquid reaches a certain volume, the condensed liquid is easily sucked into the mouth when the user inhales, causing a bad experience of choking.

In addition, the existing electronic cigarette products do not take into account the prevention of condensate backflow. When the electronic cigarette product is tilted or placed upside down, the condensed liquid remaining in the atomization chamber or the air flow channel may overflow from the air inlet or the air outlet. The spilled condensate may cause damage to the electrical components (such as the sensing device and the control device) in the electronic cigarette product, or cause a bad user experience.

In addition, the existing electronic cigarette products do not consider the pressure balance of the oil storage chamber. In existing electronic cigarette products, the oil storage chamber is generally designed to be completely sealed to prevent the atomizable solution from overflowing. As users continue to use electronic cigarette products, the atomizable solution in the oil storage chamber is continuously consumed and reduced, so that the pressure in the oil storage chamber becomes smaller and a negative pressure is formed. The negative pressure makes it difficult for the atomizable solution in the oil storage chamber to evenly flow to the heating component, so that the heating component does not uniformly absorb the atomizable solution. At this time, when the temperature of the heating element rises, there will be a high probability of empty burning and a burnt smell, resulting in a bad user experience.

Summary of the invention

In view of the above, the present disclosure proposes an atomizing device and a device for storing a solution that can solve the above problems.

An atomization device is proposed. The proposed atomization device includes a housing, a heating element, a heating element base, and a sealing element arranged on the heating element. The sealing element has a top, a bottom, and a first side wall extending between the top and the bottom. The first side wall has a first groove. The top has a second groove and the bottom has a third groove. The first groove and the heating element define a first cavity.

In some embodiments, the top cover 4 of the heating assembly may have a buckle portion. The heating element base 8 may have a snap part. The heating element top cover 4 and the heating element base 8 can be coupled by a buckle. The top cover 4 of the heating element and the base 8 of the heating element can be mechanically combined by a buckle. The top cover 4 of the heating element and the base 8 of the heating element can be removably combined by a buckle.

The heating element 6 includes a conductive element 6p. The atomizing device 100 can provide power to the heating component 6 via the conductive component 6p to increase the temperature of the heating component 6.

The sensor activation tube 7 may be a hollow tube. The sensor activation tube 7 can be arranged on one side of the heating element base 8. The sensor activation tube 7 can be arranged on the heating element base 8 on the side close to the air inlet channel.

The conductive contact 9 passes through the through hole 8h1 on the heating component base 8 to contact the conductive component 6p of the heating component 6. The conductive contact 9 can be in physical contact with the conductive component 6p. The conductive contact 9 and the conductive component 6p can be electrically connected to each other.

The base O-ring 10 can be fixed in the groove 8g 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 metal base 11 of the cartridge.

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 compartment structure 33, a compartment structure 34, an air inlet 31h, and an air outlet 32h. In some embodiments, the air inlet channel 31 and the air outlet channel 32 may be located inside the cartridge housing 3. In some embodiments, the air inlet channel 31 and the air outlet channel 32 can 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 inlet passage 31. The cartridge housing 3 and the compartment structure 34 define an air passage 32. The intake passage 31 is in fluid communication with the intake hole 31h. The air outlet channel 32 is in fluid communication with the air outlet hole 32h.

In some embodiments, the length of the compartment structure 33 is different from the length of the compartment structure 34. In some 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 air outlet 32h is greater than the maximum length 3L2 of the compartment structure 34 from the air outlet 32h. As shown in Figure 3, the difference between the length 3L1 and the length 3L2 is the length 3LD. The compartment structure 33 extends on one side of the heating element top cover 4 and the heating element base 8 (the left side as shown in FIG. 3). 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 storage tank 8t can move to the air inlet channel 31 through the gap between the heating element top cover 4 and the heating element base 8 due to capillary phenomena (see FIG. 5). The compartment structure 33 covering the heating element top cover 4 and the heating element base 8 side can prevent the liquid in the oil storage tank 8t from moving to the air inlet channel 31. The elongated compartment structure 33 can prevent the liquid in the oil storage tank 8t from leaking to the air inlet passage 31.

In some embodiments, the diameter of the inlet passage 31 may be the same as the diameter of the outlet passage 32. In some embodiments, the diameter of the inlet passage 31 may be different from the diameter of the outlet passage 32. In some embodiments, the diameter of the inlet passage 31 may be smaller than the diameter of the outlet passage 32. The smaller diameter of the intake passage 31 can make the sensor start pipe 7 easier to generate a negative pressure. The smaller diameter of the air intake passage 31 makes it easier for the sensor in the main body 100B to detect the user's inhalation action. In some embodiments, a blocking component may be further provided in the intake passage 31. As shown in FIG. 3, the air intake passage 31 includes a blocking component 35.

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

As shown in FIGS. 4A and 4B, the blocking component 35 has a first surface 35S1 and a second surface 35S2. The blocking component 35 has an opening 35O1 on the first surface 35S1. The blocking component 35 has an opening 35O2 on the second surface 35S2. The opening 35O1 extends to the opening 35O2 to form a channel 35c. The passage 35c can be regarded as a part of the intake passage 31. In some embodiments, the diameter of the opening 35O1 and the opening 35O2 may be the same. In some embodiments, the diameter of the opening 35O1 and the opening 35O2 may be different. As shown in FIG. 4A, the diameter 35L1 of the opening 35O1 may be smaller than the diameter 35L2 of the opening 35O2.

The different opening diameters of the blocking component 35 can prevent the user from producing a sharp sound when the user inhales. The different opening diameters of the blocking component 35 can prevent the sensor in the main body 100B from being misjudged by the sharp sound. The diameter 35L1 of the opening 35O1 is smaller than the diameter 35L2 of the opening 35O2 to prevent the user from producing a sharp sound when inhaling. The diameter 35L1 of the opening 35O1 is smaller than the diameter 35L2 of the opening 35O2 to avoid the misjudgment of the sensor in the main body 100B caused by the sharp sound.

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

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

The blocking component 35 may have a thickness 35T1 on the first surface 35S1. The blocking component 35 may have a thickness 35T2 on the second surface 35S2. The thickness 35T1 is greater than the thickness 35T2. The thickness 35T2 creates a height difference in the intake passage 31. Because the liquid or e-liquid stored in the oil storage tank 8t is viscous, even if the liquid or e-liquid in the oil storage tank 8t leaks to the cavity 8c2, the height difference can prevent the liquid or e-liquid from entering the air inlet channel 31 through the passage 35c . The height difference can prevent liquid or smoke oil from overflowing from the air inlet 31h.

In some embodiments, the blocking component 35 may be made of silicone. In some embodiments, the blocking component 35 may be a silicone ring. In some embodiments, the blocking component 35 can be made of the same material as the cartridge housing 3. In some embodiments, the blocking component 35 and the cartridge housing 3 may be made of different materials. In some embodiments, the blocking assembly 35 and the cartridge housing 3 may be two separate components. In some embodiments, the blocking component 35 and the cartridge housing 3 may be integrally formed.

As shown in FIG. 5, the cartridge 500A includes an oil storage tank 50, an air inlet channel 51, an air outlet channel 52, a compartment structure 53, a compartment structure 54, an air inlet 51h, and an air outlet 52h. As shown in FIG. 5, the maximum length of the compartment structure 53 from the outlet hole 52h is the same as the maximum length of the compartment structure 54 from the outlet hole 32h (the length 5L as shown in FIG. 5). No blocking component is provided in the intake passage 51. Please refer to FIGS. 3 and 5 at the same time. The length 5L of the compartment structure 53 is shorter than the length 3L1 of the compartment structure 33 in FIG.

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 top cover 4 of the heating element and the base 8 of the heating element.

In the cartridge 500A shown in FIG. 5, the condensed liquid may move from the oil storage tank 8t to the direction of the air inlet passage 51 and the air inlet hole 51h in the direction shown by the arrow 5A due to capillary phenomenon. The condensed liquid overflowing from the air inlet 51h may cause damage to the electrical components (such as the sensing device and the control device) in the electronic cigarette product or cause a bad 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 component in the air inlet passage can solve the above-mentioned problems.

In some embodiments, the angle between the surface 4s1 and the surface 4s2 of the channel 4c1 is between 160 and 180 degrees. The angular configuration between the surface 4s1 and the surface 4s2 of the channel 4c1 makes the channel 4c1 have a turning point. The angle between the surface 4s1 and the surface 4s2 of the channel 4c1 allows the e-liquid in the oil storage compartment 30 to enter the groove 6c of the heating assembly 6 more smoothly. The turning point in the channel 4c1 allows the e-liquid in the oil storage compartment 30 to enter the groove 6c of the heating assembly 6 more smoothly.

The above-mentioned channels 4c1, 4c2 enter the groove 6c of the heating assembly 6 and the angle configuration design can make the e-liquid easily flow into the groove 6c and prevent the e-liquid entering the groove 6c of the heating assembly 6 from returning to the oil storage tank 30 to maintain the storage. The quality of the smoke oil in the oil tank 30.

Referring to FIG. 6B, the heating assembly top cover 4 has an inverted assembly 4i between the channel 4c1 and the channel 4c2. The undercut component 4i includes a section 4i1, a section 4i2, a section 4i3, and a section 4i4. The section 4i1 extends in one direction. The section 4i2 extends in one direction. The section 4i3 extends in one direction. In some embodiments, the extending direction of the section 4i1 and the extending direction of the section 4i2 may be parallel. In some embodiments, the extending direction of the section 4i1 and the extending direction of the section 4i3 may be parallel. In some embodiments, the extending direction of the section 4i2 and the extending direction of the section 4i3 may be parallel. In some embodiments, the extending direction of the section 4i1 and the extending direction of the section 4i2 may not be parallel.

The section 4i1, the section 4i2, and the section 4i3 may be connected to each other via the section 4i4. In some embodiments, the extension direction of the section 4i1, the section 4i2, and the section 4i3 (the vertical direction in FIG. 6B) is substantially perpendicular to the extension direction of the section 4i4 (the horizontal direction in FIG. 6B). In some embodiments, the extending direction of the section 4i1, the section 4i2, and the section 4i3 is not perpendicular to the extending direction of the section 4i4. In some embodiments, the undercut assembly 4i may be composed of more sections. In some embodiments, the undercut assembly 4i may be composed of fewer sections.

As shown in FIG. 6B, the length of the section 4i1 is smaller than the length of the section 4i2. The length of the section 4i1 is smaller than the length of the section 4i3. In some embodiments, the length of the section 4i2 and the length of the section 4i3 may be the same. In some embodiments, the length of the section 4i2 and the length of the section 4i3 may be different. Due to the short length of the section 4i1, the e-liquid in the oil storage tank 30 is easy to flow into the groove 6c of the heating assembly 6 after passing through the turning point of the passage 4c1.

The section 4i1, the section 4i2, and the section 4i4 form a cavity 41. The section 4i2, the section 4i3, and the section 4i4 form a cavity 42. The cavity 41 has an opening 41v. The cavity 42 has an opening 42v. The openings of the cavity 41 and the cavity 42 face the direction of the groove 6c of the heating assembly 6 (the vertical downward direction in FIG. 6B). The openings of the cavity 41 and the cavity 42 and the opening of the groove 6c of the heating assembly 6 face opposite directions. The cavity 41 is in fluid communication with the groove 6c of the heating assembly 6 via the opening 41v. The cavity 42 is in fluid communication with the groove 6c of the heating assembly 6 via the opening 42v.

In some embodiments, the undercut component 4i may have an additional cavity other than the cavity 41 and the cavity 42. In some embodiments, the undercut component 4i may have a single cavity.

During the continuous use of the atomizing device 100, the atomizing material in the oil storage tank 30 is continuously consumed, causing bubbles to be generated in the oil storage tank 30. In some embodiments, the atomizable material (such as e-liquid) may directly contact the heating element 6 via the inner wall of the groove 6c. During the heating process of the atomizing device, air bubbles may also be generated in the heating assembly 6.

Since the inverted component 4i has a cavity 41 and a cavity 42, a part of the above-mentioned bubbles can be collected or accumulated in the cavity 41 and the cavity 42, thereby dispersing the overall bubble volume of the oil storage tank 30. Reducing the volume of bubbles in the oil storage tank 30 can prevent the bubbles from blocking the channel 4c1 or the channel 4c2. Reducing the volume of air bubbles in the oil storage tank 30 can avoid the problem of irregular oil intake. According to this, the atomizable material (such as e-liquid) in the oil storage tank 30 can be uniformly flowed to the heating component, and the heating component can uniformly adsorb the atomizable material (such as e-liquid).

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

As shown in FIGS. 7A, 7B, and 7C, the heating element sealing member 5 has a top 501, a bottom 503, and a side wall 505 extending between the top 501 and the bottom 503. The side wall 505 has a groove 5g1. The top 501 of the heating assembly seal 5 has a groove 5g2. The bottom 503 of the heating assembly seal 5 has a groove 5g3.

The side wall 505 includes a partition 5p, and the partition 5p includes a section 5p1 and a section 5p2, and one end of the section 5p1 is directly connected to one end of the section 5p2. The other end of the section 5p1 and one side 5s1 of the groove 5g1 form a gap 5v1. The other end of the section 5p2 and the other side 5s2 of the groove 5g1 form a gap 5v2. In some embodiments, the angle θ ₁ between the section 5p1 and the section 5p2 is between 90 and 180 degrees. In some embodiments, the angle θ ₁ between the section 5p1 and the section 5p2 is between 90 and 120 degrees. In some embodiments, the angle θ ₁ between the section 5p1 and the section 5p2 is between 120 and 150 degrees. In some embodiments, the angle θ ₁ between the section 5p1 and the section 5p2 is between 150 and 180 degrees. In some embodiments, the section 5p1 and the section 5p2 form a V-shape with an opening facing upward (for example, the vertical upward direction shown in FIG. 7B).

The side wall 505 of the heating element seal 5 further includes a partition 5q. The second partition 5q includes a section 5q1 and a section 5q2. A gap 5v3 is formed between the section 5q1 and the section 5q2. _{There is an angle θ 2} between the section 5q1 and the section 5q2. In certain embodiments, the angle between the segments and 5q1 5q2 θ the angle between the segment and the segment 5p1 and 5p2 ₂ θ ₁ may be different segments. In certain embodiments, the angle between the segments 5q1 5q2 [theta] and the angle between the segment and the segment 5p1 and 5p2 ₂ θ ₁ may be the same segment. In some embodiments, the section 5p1 and the section 5p2 form an inverted V shape with an opening facing downward (for example, the vertical downward direction shown in FIG. 7B).

When the heating element sealing member 5 covers the heating element 6, at least one cavity (or called an air-permeable channel) is defined between the partition member 5p, the partition member 5q, the groove 5g1, and the heating member 6. In detail, the groove 5g3, the gap 5v3, the gap 5v1, and the groove 5g2 can define the air-permeable channel 5c1 (as shown in FIG. 7D). The atomization chamber 8c can be in fluid communication with the oil storage tank (the oil storage tank 30 shown in FIG. 3) through the air-permeable passage 5c1. The groove 5g3, the gap 5v3, the gap 5v2, and the groove 5g2 can define a gas-permeable channel 5c2 (as shown in FIG. 7D). The atomization chamber 8c can be in fluid communication with the oil storage tank (the oil storage tank 30 as shown in FIG. 3) through the air-permeable passage 5c2.

As the user continues to use the atomizing device, the atomizable material in the oil storage tank 30 is continuously consumed and reduced, so that the pressure in the oil storage tank 30 gradually decreases. When the pressure in the oil storage tank 30 decreases, negative pressure may be generated. The decrease in the pressure in the oil storage compartment 30 may make it difficult for atomizable materials (such as e-liquid) to flow to the groove 6c of the heating assembly 6 through the channels 4c1 and 4c2. When the groove 6c does not completely absorb the atomizable material, the high-temperature heating element 6 may burn dry and produce a burnt smell.

The above-mentioned problem can be improved by arranging the air-permeable channel in the side wall of the heating element sealing member 5. The air-permeable passage (the flow direction shown by the arrow in FIG. 7D) formed in the side wall of the heating element seal 5 can balance the pressure in the oil storage tank 30.

The partition 8p2 is disposed between the groove 8g1 and the groove 8g5.

At least one cavity (or called a gas-permeable channel) is defined between the partitions 8p1, 8p2, the grooves 8g1-8g5 and the heating element 6. In detail, the grooves 8g3, 8g1, 8g2, and the partitions 8p1, 8p2 define the first air-permeable passage.

The arrangement of the through holes 81h is designed to allow gas to pass through. In some embodiments, the support member 81 may include more through holes. In some embodiments, the support member 81 may include fewer through holes.

The aperture area of the through hole 81h is designed to make it difficult for e-liquid to pass through. The arrangement of the through holes 81h is designed to make it difficult for e-liquid to pass through. In some embodiments, the diameter of each of the through holes 81h is in the range of 0.2 mm to 0.3 mm. In some embodiments, the diameter of each of the through holes 81h is in the range of 0.3 mm to 0.4 mm.
