Description
Technical Field
The present disclosure relates generally to an aerosolization device and heating assembly thereof, and more particularly to an aerosol generating electronic device and heating assembly thereof.
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.
The existing electronic cigarette products have different defects. For example, a common electronic cigarette product uses a cotton wick and a metal heater as a heating element. The heating wire of the heating component only partially wraps the cotton core. If the density of the heating wire and the cotton core is not particularly considered in the manufacturing process, poor contact between the heating wire and the cotton core is often caused. Poor contact may result in heat generated by the heater not being transferred to the smoke. Poor contact can result in excessive local temperature of the heater, which can scorch the cotton core and produce a scorched smell. Burnt cotton cores may also produce substances that are harmful to humans.
In addition, the prior art electronic cigarette products may have poor assembly yield for reducing the number of components. Prior art electronic cigarette products may instead increase component manufacturing costs in order to reduce the number of components. Furthermore, prior art electronic cigarette products may not account for the high temperature of the aerosol, creating a potential risk of user burns.
Therefore, an atomization device capable of solving the above problems is provided.

In some embodiments, the cartridge housing 2 may have more ribs on the inner wall. In certain embodiments, the cartridge housing 2 inner wall may have fewer ribs. In certain embodiments, the cartridge housing 2 inner wall may have a total of 6 ribs.
The first 2r1, second 2r2, third 2r3 and fourth 2r4 ribs extend from the portion of the cartridge housing 2 adjacent the aperture 1h of the mouthpiece cover 1 towards the heating assembly lid 4. One end of the first rib 2r1, the second rib 2r2, the third rib 2r3, and the fourth rib 2r4 is in direct contact with the heating module top cover 4. One ends of the first rib 2r1, the second rib 2r2, the third rib 2r3 and the fourth rib 2r4 are pressed against a part of the heating element top cover 4. As shown in fig. 4A within the dashed circle a, the third rib 2r3 presses against a portion of the heating element top cover 4. The first rib 2r1, the second rib 2r2, the third rib 2r3 and the fourth rib 2r4 prevent the heating element cover 4 from being separated from the heating element base 6.
The first rib 2r1, the second rib 2r2, the third rib 2r3, and the fourth rib 2r4 may reinforce the rigidity of the cartridge case 2. The first rib 2r1, the second rib 2r2, the third rib 2r3 and the fourth rib 2r4 prevent the cartridge case 2 from being deformed by external force. The first rib 2r1, the second rib 2r2, the third rib 2r3 and the fourth rib 2r4 prevent the tobacco tar in the storage compartment 30 from overflowing due to the external force.
The heating assembly top cover 4 and the heating assembly base 6 define an atomization chamber 40. The atomization chamber 40 can be a cavity between the heating assembly top cover 4 and the heating assembly base 6.
The heating assembly 5 has a length of 5L. The atomizing chamber 40 has a maximum width of 4L 1. The length 5L of the heating assembly 5 is greater than the maximum width 4L1 of the nebulizing chamber 40.
A portion of the heating element 5 is disposed within the atomizing chamber 40. The ends of the heating module 5 extend from the aperture 4h of the heating module top cover 4 into the storage compartment 30. The heating element top cover 4 exposes a portion of the heating element 5. The heating block top cover 4 exposes both end portions of the heating block 5. Both ends of the heating unit 5 are exposed to the storage compartment 30. The tobacco tar in the storage compartment 30 can be adsorbed by the heating element 5 through both ends of the heating element 5. The tobacco tar adsorbed on the heating assembly 5 is heated by the heating circuit 51 to generate aerosol in the atomizing chamber 40. The aerosol may be inhaled by the user via the airflow channel 100t formed by the second tube 4t2 of the heating assembly top cap 4, the tube 2t of the cartridge housing 2 and the tube 1t of the mouthpiece cover 1.
In some embodiments, the heating assembly 5 may be replaced with the heating assembly 500 shown in fig. 3A. In some embodiments, the heating assembly 5 may be replaced with the heating assembly 501 shown in fig. 3C. In some embodiments, the heating assembly 5 may be replaced with the heating assembly 502 shown in fig. 4A. In some embodiments, the heating assembly 5 may be replaced with the heating assembly 503 shown in FIG. 4B.
In some embodiments, the mouthpiece cover 1 and the cartridge housing 2 may be integrally formed, with the tube 2t of the cartridge housing 2 and the tube 1t of the mouthpiece cover 1 being the same component.
The airflow channel 100t formed by the second tube 4t2 of the heating assembly top cover 4, the tube 2t of the cartridge housing 2 and the tube 1t of the mouthpiece cover 1 may have a smooth inner diameter. The inner diameter of the air flow channel 100t does not have a significant step difference at the junction of the tube 1t of the mouthpiece cover 1 and the tube 2t of the cartridge housing 2. The inner diameter of the air flow channel 100t does not have a significant step difference at the point where the tube 2t of the cartridge housing 2 meets the second tube 4t2 of the heating assembly top cover 4. The inner diameter of the airflow channel 100t does not have a distinct interface where the tube 1t of the mouthpiece cover 1 meets the tube 2t of the cartridge housing 2. The inner diameter of the airflow passage 100t does not have a distinct interface where the tube 2t of the cartridge housing 2 meets the second tube 4t2 of the heating assembly top cover 4.
The airflow channel 100t formed by the second tube 4t2 of the heating assembly top cap 4, the tube 2t of the cartridge housing 2 and the tube 1t of the mouthpiece cover 1 may have non-uniform inner diameter sizes. For example, the tube 2t of the cartridge housing 2 may have inner diameters 2L1 and 2L2, and the inner diameter 2L1 is greater than 2L 2. The tube 1t of the mouthpiece cover 1 has internal diameters 1L1 and 1L2, and the internal diameter 1L1 is greater than 1L 2. In certain embodiments, the airflow channel formed by the second tube 4t2 of the heating assembly top cap 4, the tube 2t of the cartridge housing 2, and the tube 1t of the mouthpiece cover 1 may have a uniform inner diameter.
Referring to fig. 5B, the heating element top cover 4 may have two portions. A portion of the heating assembly top cover 4 has a larger width. The inner wall of the atomizing chamber 40 may have a non-uniform width. For example, the inner wall of the atomizing chamber 40 has a width of 4L2 and a maximum width of 4L1 due to the shape of the heating element top cover 4. Width 4L2 is less than width 4L 1. The distance between the heating assembly 5 and the portion of the width 4L1 of the atomizing chamber 40 is less than the distance between the heating assembly 5 and the portion of the width 4L2 of the atomizing chamber 40.
The sealing assembly 3 is disposed between the tube 2t of the cartridge housing 2 and the first tube 4t1 of the heating assembly top cover 4. The seal assembly 3 may have a hardness less than the hardness of the cartridge housing 2. The seal assembly 3 may have a hardness less than the hardness of the heating assembly top cover 4. The sealing assembly 3 may increase the degree of seal between the tube 2t of the cartridge housing 2 and the first tube 4t1 of the heating assembly top cover 4. The sealing assembly 3 reduces the tolerance requirements of the tube 2t of the cartridge housing 2 and the first tube 4t1 of the heating assembly top cover 4. The sealing assembly 3 can reduce the difficulty of manufacturing the cartridge housing 2 and the heating assembly top cover 4. The sealing assembly 3 prevents damage to the cartridge housing 2 and the heating assembly top cover 4 during assembly.
The second tube 4t2 of the heating assembly top cover 4 may have an inner diameter smaller than the first tube 4t1 of the heating assembly top cover 4. The second tube 4t2 of the heating assembly top cover 4 may have an outer diameter smaller than the first tube 4t1 of the heating assembly top cover 4. The second tube 4t2 of the heating assembly top cover 4 extends into the atomizing chamber 40. The second tube 4t2 of the heating assembly top cover 4 extends into the atomizing chamber 40. The second tube 4t2 of the heating assembly top cover 4 extends in a direction opposite to the aperture 1h of the mouthpiece cover 1. The second tube 4t2 of the heating assembly top cover 4 may bring the airflow path closer to the heating assembly 5. The second tube 4t2 of the heating assembly top cover 4 can enable the aerosol generated in the nebulizing chamber 40 to be more completely discharged from the air flow channel. The second tube 4t2 of the heating element top cover 4 prevents the aerosol generated in the atomizing chamber 40 from leaking into the storage compartment 30 from the gap between the sealing member 3 and the heating element top cover 4.
See fig. 5B. When a user inhales from the hole 1h of the mouthpiece cover 1, an airflow 100f is generated within the cartridge 100A. The front segment of the air flow 100f contains fresh air that enters the aerosolizing chamber 40 through the first aperture 7h1 of the cartridge base 7. The rear section of the airflow 100f contains the aerosol generated by the heating assembly 5. Fresh air enters the nebulization chamber 40 via the first aperture 7h1 of the cartridge base 7 and the aerosol generated by the heating assembly 5 is expelled along the airflow channel 100t from the aperture 1h reaching the mouthpiece cover 1.
The air flow 100f produces a temperature change between the heating element 5 and the second tube 4t2 of the heating element top cover 4. The aerosol generated by the heating assembly 5 undergoes a temperature change before reaching the second tube 4t2 of the heating assembly top cover 4.
The non-uniform width of the inner wall of the atomizing chamber 40 may enhance the temperature change of the air flow 100 f. The non-uniform width of the inner wall of the atomizing chamber 40 may accelerate the temperature change of the air flow 100 f. The temperature of the airflow 100f decreases from the width of 4L1 to 4L 2. The temperature drop is greater and faster when the air stream 100f flows from the width of 4L1 to 4L2 as compared to an atomizing chamber having a uniform inner wall width. By adjusting the width of the inner wall of the atomizing chamber 40, the temperature of the aerosol sucked from the hole 1h of the mouthpiece cover 1 by the user can be controlled. In some embodiments, the atomization chamber 40 may also have substantially the same inner wall width.
After entering the atomizing chamber 40 from the first hole 7h1 of the cartridge base 7, the airflow 100f is heated by the heating element 5 to generate a temperature rise Tr. In certain embodiments, the temperature rise Tr may be in the range of 200 ℃ to 220 ℃. In certain embodiments, the temperature rise Tr may be in the range of 240 ℃ to 260 ℃. In certain embodiments, the temperature rise Tr may be in the range of 260 ℃ to 280 ℃. In certain embodiments, the temperature rise Tr may be in the range of 280 ℃ to 300 ℃. In certain embodiments, the temperature rise Tr may be in the range of 300 ℃ to 320 ℃. In certain embodiments, the temperature rise Tr may be in the range of 200 ℃ to 320 ℃.
The air flow from the atomising chamber 40 may produce a temperature drop Tf before reaching the aperture 1h of the mouthpiece cover 1. In certain embodiments, the temperature drop Tf may be in the range of 145 ℃ to 165 ℃. In certain embodiments, the temperature drop Tf may be in the range of 165 ℃ to 185 ℃. In certain embodiments, the temperature drop Tf may be in the range of 205 ℃ to 225 ℃. In certain embodiments, the temperature drop Tf may be in the range of 225 ℃ to 245 ℃. In certain embodiments, the temperature drop Tf may be in the range of 245 ℃ to 265 ℃. In certain embodiments, the temperature drop Tf may be in the range of 145 ℃ to 265 ℃.
The airflow passage 100t may have a non-uniform inner diameter. The inner diameter of the airflow passage 100t gradually increases from the position near the heating element 5 toward the hole 1h of the mouthpiece cover 1. The larger inner diameter near the aperture 1h of the mouthpiece cover 1 may make the aerosol volume larger.
By adjusting the width of the inner wall of the atomizing chamber 40 and the inner diameter of the air flow passage 100t, the temperature of the aerosol sucked from the hole 1h of the mouthpiece cover 1 by the user can be controlled. By adjusting the width of the inner wall of the atomizing chamber 40 and the inner diameter of the air flow passage 100t, the volume of the aerosol sucked from the hole 1h of the mouthpiece cover 1 by the user can be controlled.
The temperature of the aerosol can be controlled to avoid the user from being scalded by the aerosol. Controlling the aerosol volume can enhance the inhalation experience for the user.
In certain embodiments, the aerosol inhaled by the user via the aperture 1h of the mouthpiece cover 1 may have a temperature below 65 ℃. In certain embodiments, the aerosol inhaled by the user via the aperture 1h of the mouthpiece cover 1 may have a temperature below 55 ℃. In certain embodiments, the aerosol inhaled by the user via the aperture 1h of the mouthpiece cover 1 may have a temperature below 50 ℃. In certain embodiments, the aerosol inhaled by the user via the aperture 1h of the mouthpiece cover 1 may have a temperature below 45 ℃. In certain embodiments, the aerosol inhaled by the user via the aperture 1h of the mouthpiece cover 1 may have a temperature below 40 ℃. In certain embodiments, the aerosol inhaled by the user via the aperture 1h of the mouthpiece cover 1 may have a temperature below 30 ℃.
