Description

Technical Field

[0001] This invention relates to the field of atomizer technology, and more particularly to an atomizing module and atomizing device thereof. Background Technology

[0002] Electronic atomizing devices are devices that use electricity to heat and atomize a liquid. They are currently widely used in the field of electronic atomizers. Electronic atomizers have become popular in recent years as a new type of tobacco product due to their cigarette-like experience. The atomizer coil, as the core of an electronic cigarette, plays a crucial role. The atomization process is mainly determined by several factors: the amount and path of air entering the atomizer (commonly known as the air path); the location, amount, and length of the e-liquid inlet (commonly known as the e-liquid path); the heating circuitry (the electrical circuitry); and the reduced air pressure in the e-liquid tank after liquid consumption, leading to poor liquid flow (meaning air exchange must also be considered). Changes or mismatches in any of these parameters can easily result in poor atomization and various other problems. Because they need to cater to consumers in different regions, their appearance varies greatly. With these changes, the internal structure also changes, which often leads to modifications in atomization parameters. Therefore, there is a need to provide a modular atomization device. The module integrates the air path, oil path, circuit, and ventilation into a simple package to meet the needs of more users. This allows the atomization device to guarantee atomization effect simply by using this atomization module. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Figures 1-10This invention illustrates an atomizing module according to some preferred embodiments, comprising a support 1, a liquid guide 2, a heating element 3, a sealing gasket 4, and a base 5. The support 1 is made of plastic, ceramic, or metal and can be mass-produced using a mold-forming process. To facilitate matching with various liquid storage tanks, the support 1 is generally cylindrical in shape, preferably using a cylindrical structure. The support 1 is vertically continuous and contains an installation chamber 11. The support 1 serves a supporting function and encapsulates the liquid guide 2 and the heating element 3. The liquid guide 2, the heating element 3, and the sealing gasket 4 are all disposed within the installation chamber 11. The heating element 3 is attached to the bottom of the liquid guide 2, which conducts liquid to the heating element 3, which heats and atomizes the liquid. The sealing gasket 4 is disposed between the support 1 and the liquid guide 2 to seal the liquid guide 2 and the support 1, preventing leakage. The base 5 is disposed at the bottom opening of the support 1 to encapsulate the bottom of the support 1.

[0043] Furthermore, such as Figure 3 As shown, the support has a columnar structure, and the mounting chamber 11 extends laterally through both sides of the support 1 to form a first liquid inlet 12. The first liquid inlet 12 is connected to the liquid guide 2 to form a liquid inlet channel A. The atomized liquid in the oil storage tank enters the mounting chamber 11 of the support 1 through the first liquid inlet 12, is conducted to the liquid guide 2, and is atomized by the heated body 3. Figure 4 , Figure 8 As shown, an airflow gap 19 is left between the mounting chamber 11 and the outer wall of the bracket 1. The mounting chamber 11 divides the bracket 1 into upper and lower parts. The lower part is provided with a receiving groove 13 facing the base 5. The sealing gasket 4 abuts against the receiving groove 13, and the liquid guide 2 abuts against the sealing gasket 4. The side of the bracket 1 with the receiving groove 13 is the air inlet end, and the other side is the mist outlet end. The air inlet end, the airflow gap 19 and the mist outlet end are connected to form an airflow channel B. Outside air enters the bracket 1 from the air inlet end and mixes with the atomized gas in the mounting chamber 11 to form an aerosol. The aerosol is discharged through the mist outlet end. The base 5 is located at the air inlet end and has an air inlet 51. Outside air enters the bracket 1 from the air inlet end and mixes with the atomized gas in the mounting chamber 11 to form an aerosol. The aerosol is discharged through the mist outlet end.

[0044] like Figure 5 , Figures 7-8As shown, the mounting chamber 11 has a receiving groove 13 and a ventilation groove 14 connected to the receiving groove 13 on the side facing the base 5. The receiving groove 13 is adapted to the sealing gasket 4, and the sealing gasket 4 abuts against the receiving groove 13 to seal the liquid guide 2 and the bracket 1. The depth of the ventilation groove 14 is greater than the depth of the receiving groove 13, so that a gap is formed between the top surface of the sealing gasket 4 and the depth of the sealing gasket 4. The ventilation groove 14 is connected to the first liquid inlet 12. The liquid guide 2, the ventilation groove 14 and the first liquid inlet 12 are connected to form a ventilation channel C. This arrangement makes it difficult for the atomized liquid to leak out from the ventilation groove 14 due to capillary force. When the air pressure in the oil storage tank is too low, the gas in the mounting chamber 11 can enter the oil storage tank from the ventilation groove 14, avoiding the problem of poor liquid guide due to the decrease in air pressure in the oil storage tank after the atomized liquid is consumed, avoiding problems such as dry burning, and improving the atomization experience.

[0045] This invention provides an atomizing module that, through peripheral encapsulation, achieves a convenient assembly shape. Internally, it features a stable liquid inlet channel A, a gas channel B, an air exchange channel C, and circuitry, allowing it to be used simply by fitting the atomizing module into the oil reservoir. It boasts high integration, requiring only an external oil reservoir for operation; strong versatility, applicable to atomizer structures with various oil reservoirs, simplifying the development of finished electronic atomizers; and subsequent assembly with an oil reservoir is simple and convenient. Modularization facilitates large-scale mass production. By setting up an air exchange channel 14 connected to the receiving tank 13, the depth of the air exchange channel 14 is greater than that of the receiving tank 13, and the air exchange channel 14 is connected to the liquid inlet, so that the guiding liquid 2, the air exchange channel 14 and the first liquid inlet 12 are connected to form an air exchange channel C. This makes it difficult for the atomized liquid to leak out of the air exchange channel 14 due to capillary force. When the air pressure in the oil storage tank is too low, the gas in the installation chamber 11 can enter the oil storage tank from the air exchange channel 14, avoiding the problem of poor liquid guiding caused by the low air pressure after the atomized liquid in the oil storage tank is consumed, avoiding problems such as dry burning, and improving the atomization experience.

[0046] Furthermore, in some preferred embodiments, such as Figure 8-9As shown, the ventilation groove 14 includes a first ventilation groove 141 and a second ventilation groove 142 communicating with the first ventilation groove 141. The first ventilation groove 141 is offset from the receiving groove 13, and the second ventilation groove 142 is disposed on the receiving groove 13 and communicates with the first liquid inlet 12. It can be understood that the sealing gasket 4 abuts against the receiving groove 13 and also partially covers the second ventilation groove 142. The top surface of the sealing gasket 4 is a certain distance from the groove depth of the second ventilation groove 142. The second ventilation groove 142 is connected to the first liquid inlet. The connection between 12 makes it difficult for the atomized liquid to leak from the second ventilation groove 142 due to the force of capillary action and the combined effect of the sealing gasket 4. When the air pressure in the oil storage tank is too low, the gas in the installation chamber 11 can enter from the first ventilation groove 141 to the second ventilation groove 142, and then to the first liquid inlet 12, and finally enter the oil storage tank. This avoids the problem of poor liquid flow caused by the reduced air pressure after the liquid in the oil storage tank is consumed, and avoids problems such as dry burning, thus improving the atomization experience.

[0047] Furthermore, in some preferred embodiments, the distance between the plane where the top surface of the sealing gasket 4 is located and the plane where the bottom of the second ventilation groove 142 is located is 0.1-0.6 mm. This distance is small enough that the atomized liquid is not easy to leak from the second ventilation groove 142 due to the force of capillary action and the combined effect of the sealing gasket 4. When the air pressure in the oil storage tank is too low, the gas can enter the oil storage tank from the first ventilation groove 141 through the second ventilation groove 142, avoiding the problem of poor liquid flow caused by the decrease in air pressure in the oil storage tank after liquid consumption.

[0048] Furthermore, in some preferred embodiments, such as Figures 3-8 As shown, an annular protrusion 15 is provided on the inner wall of the bracket 1 facing the center of the bracket 1. The inner walls of the annular protrusion 15 enclose to form a second liquid inlet 16. The first liquid inlet 12 is connected to the second liquid inlet 16. The annular protrusion 15 and the lower inner wall surface of the bracket 1 define the installation chamber 11. A receiving groove 13 is opened on the annular protrusion 15. The top surface of the sealing gasket 4 abuts against the annular protrusion 15.

[0049] Furthermore, in some preferred embodiments, such as Figure 3 As shown, a flow guide 17 extends from the upper wall of the first inlet 12 towards the second inlet 16 inside the support 1, such that the cross-sectional area from the first inlet 12 to the second inlet 16 gradually decreases along the direction close to the central axis of the support 1. This arrangement effectively guides and converges the flow, ensuring sufficient flow supply while avoiding occupying internal space, allowing for a more compact overall structure. Simultaneously, the inclined flow guide 17 facilitates faster access of air bubbles to the oil storage tank, preventing bubble accumulation that could obstruct liquid entry.

[0050] Furthermore, in some preferred embodiments, the first liquid inlet 12 is symmetrically arranged on the side wall of the support 1, and correspondingly, the guide portion 17 is symmetrically arranged to accelerate the liquid inlet rate and ensure uniform liquid inlet.

[0051] Furthermore, in some preferred embodiments, such as Figures 2-3 As shown, a liquid guide port 41 is provided on the sealing gasket 4. The liquid guide port 41 is connected to the second liquid inlet 16. The liquid guide port 41 is set to correspond to the liquid inlet surface 23 of the liquid 2, so that the liquid entering the second liquid inlet 16 enters the liquid 2 through the liquid guide port 41.

[0052] Furthermore, in some preferred embodiments, such as Figures 7-9 As shown, the installation chamber 11 is also provided with a limiting part 18. Multiple limiting parts 18 with porous structures are provided along the edge of the receiving groove 13. The limiting part 18 is in contact with the liquid guide 2 and the support 1. The bottom plane of the liquid guide 2 is higher than the bottom plane of the limiting part 18. The limiting part 18 serves two purposes: firstly, it provides positioning and limiting, allowing the liquid guide 2 to be quickly installed in the installation position and preventing it from shifting due to external forces; secondly, the limiting part 18 can also collect condensate. After the atomized liquid vaporizes, it forms atomized gas. The atomized gas mixes with air to form an aerosol. When the aerosol cools, it forms condensate. If too much condensate accumulates on the inner wall of the support 1, the limiting part 18 can lock the condensate in, and then conduct it to the liquid guide 2, where it is reheated and atomized by the heating element 3. This further prevents condensate leakage and improves the utilization rate of the atomized liquid.

[0053] Furthermore, in some preferred embodiments, such as Figure 3 As shown, a liquid storage tank 21 is formed on the top surface of the liquid guide 2 facing the liquid guide port 41. The liquid storage tank 21 is connected to the liquid guide port 41, and the inner wall of the liquid storage tank 21 forms an inlet surface 23. The liquid guide 2 includes an inlet surface 23 and an atomizing surface 22 that is opposite to and backs to the inlet surface 23. A heating element 3 is attached to the atomizing surface 22. The atomized liquid entering from the first liquid inlet 12 is drawn into and collected in the liquid storage tank 21, guided through the inlet surface 23 to the atomizing surface 22, and heated and atomized by the heating element 3. The upper surface of the liquid guide 2 is shaped to fit the sealing gasket 4, preferably a plane extending along the cross-section of the sealing gasket 4.

[0054] Furthermore, in some preferred embodiments, the liquid guide 2 has a porous structure. The liquid guide 2 can be made of a material with capillary channels or pores, such as fiber cotton, porous ceramic body, fiberglass rope, porous glass ceramic, porous glass, etc., which are hard or rigid capillary structures. The pore size of the micropores on the liquid guide 2 is 0.2 micrometers to 200 micrometers. The micropores can play the role of conducting atomized liquid. At the same time, due to the small size of the micropores, an oil film can be formed. With the effect of negative pressure, the liquid in the oil storage tank can be contained, making the liquid less likely to drip.

[0055] Furthermore, in some preferred embodiments, such as Figures 1-6 As shown, the atomizing module also includes an external electrode 6. An electrode hole 52 is provided on the base 5. The heating element 3 includes a heating circuit 31 and electrode connectors 32 extending from both sides of the heating circuit 31. The external electrode 6 passes through the electrode hole 52 and is electrically connected to the electrode connectors 32. The heating element 3 can be formed on the atomizing surface 22 of the liquid guide 2 by methods such as mounting, printing, or deposition. The heating element 3 can be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, titanium, conductive metal fibers, conductive carbon fibers, or conductive graphite fibers. The heating circuit 31 can have a meandering, circuitous, or other patterned conductive trajectory, and electrode connectors 32 can be provided at both ends. The electrode connectors 32 can be in the form of gaskets or leads. The electrode connectors 32 and the external electrode 6 are electrically connected to provide power to the atomizing module from the power supply device.

[0056] Furthermore, in some preferred embodiments, the support 1 is a columnar structure; in order to facilitate matching with various oil storage tanks, the support 1 is columnar in shape, preferably a cylindrical structure; this simplifies the development of finished electronic devices, and makes the subsequent assembly with oil storage tanks simple and convenient, which is conducive to large-scale mass production.

[0057] The present invention also provides an atomizing device, such as Figures 10-13As shown, the atomizing component and the oil storage tank component 200 are included. The oil storage tank component 200 includes a housing 7, a bottom plug 8 disposed at the bottom of the housing 7, an oil storage tank 9 disposed inside the housing 7, and an air guide pipe 10 disposed between the housing 7 and the oil storage tank 9. The bottom plug 8 is provided with a mounting position 81 adapted to the atomizing module 100. The bracket 1 of the atomizing module 100 is inserted into the air guide pipe 10 or sleeved on the outside of the air guide pipe 10 through the mounting position 81. Before use, the atomizing module 100 is partially exposed outside the bottom plug 8, and the first liquid inlet 12 of the atomizing module 100 is blocked by the inner wall of the bottom plug 8. Understandably, the oil reservoir 9 stores atomizing liquid. Before use, the guide liquid 2 does not come into contact with the atomizing liquid, and the first liquid inlet 12 of the atomizing module 100 is blocked by the sealing part of the oil reservoir assembly 200. At this time, the atomizing liquid is not in contact with the guide liquid 2. When using, push the atomizing module 100 into the oil reservoir assembly 200 until the base 5 of the atomizing module 100 is flush with or nearly flush with the bottom of the bottom plug 8. The first liquid inlet 12 is exposed in the oil reservoir 9, and the atomizing liquid in the oil reservoir 9 flows into the first liquid inlet 12 of the atomizing module 100 due to gravity. This design is beneficial for transportation, ensuring that the atomizing liquid will not leak during transportation. At the same time, it can avoid the problem of corrosion of the heating element 3 due to prolonged contact between the guide liquid 2 and the heating element 3 on the guide liquid 2 during storage.

[0058] Furthermore, in some preferred embodiments, a flexible first seal 201 is provided at the connection between the atomizing module 100, the air duct 10 and the oil storage tank 9, and a flexible second seal 202 is provided at the connection between the atomizing module 100, the oil storage tank 9 and the bottom plug 8, to ensure airtightness and prevent leakage of atomized liquid from the connection.

[0059] Specifically, the first sealing element 201 can be sleeved on the outer wall of the air guide tube 10. A sealing groove 2011 is provided on the outside of the first sealing element 201. The sealing groove 2011 is adapted to the top opening end of the bracket 1, and the bracket 1 is snapped into the sealing groove 2011. The second sealing element 202 is provided between the bottom plug 8 and the outer shell 7. The second sealing element 202 has a through hole 2021 reserved at the corresponding mounting position 81. The diameter of the through hole 2021 matches the outer diameter of the bracket 1. The bracket 1 passes through the through hole 2021 and connects to the first sealing element 201 of the air guide tube 10. The second sealing element 202 seals the atomizing module 100, the oil storage tank 9 and the bottom plug 8. The first sealing element 201 seals the atomizing module 100, the air guide tube 10 and the oil storage tank 9.

[0060] Furthermore, a step 102 is formed in the bottom recess 101 of the air duct 10. The first sealing member 201 is fitted into the recess 101 and can move relative to the extension direction of the air duct 10. The step 102 limits the first sealing member 201. Before use, the bracket 1 of the atomizing module 100 is snapped onto the first sealing member 201. The first sealing member 201 is not held against the step 102. The atomizing module 100 is partially exposed outside the bottom plug 8, so that the first liquid inlet 12 is blocked by the inner wall of the second sealing member 202. When in use, external force is applied to the atomizing module 10. Pushing upwards, the first seal 201 moves upwards along the air guide tube 10 until it is limited by the step 102. At this time, the bottom of the atomizing module 100 is flush with the bottom of the bottom plug 8, and the first liquid inlet 12 is exposed in the oil storage tank 9. The atomized liquid in the oil storage tank 9 flows into the first liquid inlet 12 of the atomizing module 100 due to gravity. This design is beneficial for transportation and can ensure that the atomized liquid will not leak during transportation. At the same time, it can avoid the problem of corrosion of the heating element 3 due to prolonged contact between the guide liquid 2 and the heating element 3 on the guide liquid 2 during storage.
