Description

[Technical Field]

[0001] The present invention relates to the technical field of atomizers, and in particular to an atomization module and its atomization device. [Background technology]

[0002] Electronic atomizers use electricity to heat and atomize liquids. They are currently widely used in the electronic atomizer field. Furthermore, because electronic atomizers offer a similar sensation to cigarettes, they have become popular as a new tobacco product in recent years. The atomization core plays an important role as the core of electronic cigarettes. The atomization process is primarily determined by several components. The amount and path of air entering during atomization are commonly referred to as the airflow path. The location of liquid entry, the amount of liquid entering, and the length of the liquid entry path are commonly referred to as the liquid path. Electronic cigarettes also have a heating circuit. That is, they are influenced by the electrical circuit. Furthermore, as liquid is consumed, the air pressure in the liquid tank decreases, causing irregular liquid flow, so ventilation must also be considered. However, parameter fluctuations or mismatches often reduce the atomization effect, resulting in various problems. The need to satisfy consumers in different regions requires a wide range of external modifications. These variations in the internal structure also lead to changes in the atomization parameters. Therefore, in order to satisfy more users, it is necessary to provide a modularized atomization device that simply encapsulates the airflow path, liquid path, electrical circuitry, and ventilation. By simply adopting this atomization module, the atomization device can guarantee the atomization effect. Summary of the Invention [Problem to be solved by the invention]

[0034] 1 to 10 show an atomization module including a holder 1, a liquid guide 2, a heating element 3, a gasket 4, and a bottom base 5 in some preferred embodiments of the present invention. The holder 1 is made of plastic, ceramic, or metal and can be manufactured using a mass molding process. To accommodate various liquid storage tanks, the holder 1 generally has a columnar outer shape, preferably a cylindrical structure. The holder 1 is perforated vertically and has an internal mounting space 11. The holder 1 provides support and encapsulates the liquid guide 2 and heating element 3. The liquid guide 2, heating element 3, and gasket 4 are all mounted within the mounting space 11. The heating element 3 is attached to the bottom of the liquid guide 2. The liquid guide 2 is used to guide the liquid to the heating element 3, and the heating element 3 is used to heat and atomize the liquid. The gasket 4 is mounted between the holder 1 and the liquid guide 2 to seal the liquid guide 2 and the holder 1 to prevent liquid leakage. The bottom base 5 is provided at the open end of the bottom of the holder 1 and is used to seal the bottom of the holder 1.

[0035] Furthermore, as shown in FIG. 3, the holder has a columnar structure. The mounting space 11 penetrates laterally through two sidewalls of the holder 1 to form a first liquid supply port 12. The first liquid supply port 12 and the liquid guide 2 are connected to form a liquid supply path A. The atomization liquid in the liquid tank enters the mounting space 11 of the holder 1 through the first liquid supply port 12 and is guided to the liquid guide 2 and atomized by the heater 3. As shown in FIGS. 4 and 8, an airflow gap 19 is maintained between the mounting space 11 and the outer wall of the holder 1. The mounting space 11 also divides the holder 1 into two parts, upper and lower, and the lower part is provided with a housing groove 13 that faces the bottom base 5. The gasket 4 abuts within the housing groove 13, and the liquid guide 2 abuts against the gasket 4. The side of the holder 1 where the housing groove 13 is provided is the air supply end, and the other side is the aerosol discharge end. The air inlet end, airflow gap 19, and aerosol discharge end are connected to form an airflow path B. Outside air enters holder 1 from the air inlet end and mixes with atomized gas in mounting space 11 to form aerosol. The aerosol is discharged through the aerosol discharge end. Bottom base 5 is provided at the air inlet end. An air inlet 51 is also formed in bottom base 5. Outside air enters holder 1 from the air inlet and mixes with atomized gas in mounting space 11 to form aerosol, which is then discharged through the aerosol discharge end.

[0036] As shown in Figures 5, 7 and 8, a receiving groove 13 and a ventilation groove 14 communicating with the receiving groove 13 are provided on the side of the mounting space 11 facing the bottom base 5. The receiving groove 13 is fitted to a gasket 4. The gasket 4 abuts against the receiving groove 13 to seal the liquid guide 2 and the holder 1. The depth of the ventilation groove 14 is greater than the depth of the receiving groove 13, so that the ceiling surface of the gasket 4 and the ventilation groove 14 are in contact with each other. Bottom of ventilation groove 14A gap is formed between the liquid supply port 12 and the ventilation groove 14. The ventilation groove 14 and the first liquid supply port 12 are also in communication with each other. The liquid guide 2, the ventilation groove 14, and the first liquid supply port 12 are in communication with each other to form a ventilation path C. By configuring the liquid in this manner, the atomization liquid is less likely to leak from the ventilation groove 14 due to the action of capillary action. Furthermore, if the air pressure inside the liquid tank drops too much, gas inside the mounting space 11 can enter the liquid tank through the ventilation groove 14. This prevents irregular liquid guide caused by a drop in air pressure inside the liquid tank after the atomization liquid has been consumed, and avoids problems such as running the device dry, improving the atomization experience.

[0037] In the atomization module provided by the present invention, the outer periphery is sealed, which gives the atomization module an outer shape that is relatively easy to assemble. Airflow path Since the atomization module has B, ventilation path C, and an electric circuit inside, it can be used by simply fitting it into the liquid tank. The atomization module is highly integrated and can be used by simply equipping it with a liquid tank on the periphery. It is also versatile and can be applied to the atomizer structure of various liquid tanks, simplifying the development of the finished electronic atomizer. It also makes it easy and convenient to assemble the liquid tank that is combined in the post-process. Modularization is also advantageous for large-scale and mass production. It also has a ventilation groove 14 that communicates with the accommodation groove 13, and the depth of the ventilation groove 14 is made greater than the depth of the accommodation groove 13, so that the ventilation groove 14 and 1st liquid supply port 12 By communicating these, a ventilation path C is formed by the communication between the liquid guide 2, the ventilation groove 14, and the first liquid supply port 12. This makes it difficult for the atomization liquid to leak from the ventilation groove 14 due to the action of capillary action. Also, if the air pressure inside the liquid tank drops too much, gas inside the mounting space 11 can enter the liquid tank through the ventilation groove 14. This prevents irregular liquid guide caused by a drop in air pressure after the atomization liquid in the liquid tank has been consumed, and avoids problems such as dry-burning, improving the atomization experience.

[0038] Furthermore, in some preferred embodiments, as shown in FIGS. 8 and 9 , the ventilation groove 14 includes a first ventilation groove 141 and a second ventilation groove 142 that communicates with the first ventilation groove 141. The first ventilation groove 141 is provided offset from the storage groove 13. The second ventilation groove 142 is provided in the storage groove 13 and communicates with the first liquid supply port 12. As can be seen, the gasket 4 abuts against the storage groove 13 and covers a portion of the second ventilation groove 142. There is also a certain distance between the ceiling surface of the gasket 4 and the depth of the second ventilation groove 142, and the second ventilation groove 142 communicates with the first liquid supply port 12. This makes it difficult for the atomization liquid to leak from the second ventilation groove 142 due to the action of capillary action and the interaction with the gasket 4. Furthermore, if the air pressure inside the liquid tank drops too much, gas inside the mounting space 11 can enter through the first ventilation groove 141 and reach the second ventilation groove 142, and then reach the first liquid supply port 12 through the second ventilation groove 142, and finally enter the liquid tank. This prevents irregular liquid flow due to a drop in air pressure after the liquid inside the liquid tank has been consumed, and avoids problems such as dry burning, improving the atomization experience.

[0039] Furthermore, in some preferred embodiments, the distance from the plane where the ceiling surface of the gasket 4 is located to the plane where the groove bottom of the second ventilation groove 142 is located is 0.1 to 0.6 mm. Because this distance is sufficiently small, the action of capillary action and the interaction with the gasket 4 make it difficult for the atomized liquid to leak from the second ventilation groove 142. Furthermore, if the air pressure inside the liquid tank drops too much, gas can enter the liquid tank from the first ventilation groove 141 via the second ventilation groove 142. This prevents irregular liquid flow due to a drop in air pressure inside the liquid tank after the liquid has been consumed.

[0040] Furthermore, in some preferred embodiments, as shown in Figures 3 to 8, an annular flange 15 is provided on the inner wall of the holder 1 toward the center of the holder 1, and a second liquid supply port 16 is formed so as to be surrounded by the inner wall of the annular flange 15. The first liquid supply port 12 and the second liquid supply port 16 are in communication. An attachment space 11 is defined by the annular flange 15 and the lower inner wall surface of the holder 1. A receiving groove 13 is opened in the annular flange 15, and the ceiling surface of the gasket 4 abuts against the annular flange 15.

[0041] Furthermore, in some preferred embodiments, as shown in FIG. 3, a flow guide portion 17 is provided within the holder 1, extending from the upper wall surface of the first liquid supply port 12 toward the second liquid supply port 16. As a result, the cross-sectional area from the first liquid supply port 12 to the second liquid supply port 16 becomes smaller as it approaches the central axis of the holder 1. This arrangement effectively utilizes the flow guide and confluence functions, and while ensuring a sufficient flow rate, it avoids occupying internal space, allowing the entire structure to be designed more compactly. In addition, the inclined flow guide portion 17 is advantageous for allowing air bubbles during ventilation to reach the liquid tank more quickly, preventing air bubbles from accumulating in this area and interfering with the entry of liquid.

[0042] Furthermore, in some preferred embodiments, the first liquid supply ports 12 are provided at least symmetrically on the side wall of the holder 1, and accordingly, the flow guide portions 17 are also provided at least symmetrically, thereby accelerating the liquid supply speed and ensuring uniform liquid supply.

[0043] Furthermore, in some preferred embodiments, as shown in Figures 2 and 3, the gasket 4 is provided with a liquid introduction port 41. The liquid introduction port 41 is in communication with the second liquid supply port 16. The liquid introduction port 41 is also provided in correspondence with the liquid supply surface 23 of the liquid guide 2. As a result, the liquid that has entered the second liquid supply port 16 enters the liquid guide 2 through the liquid introduction port 41.

[0044] Furthermore, in some preferred embodiments, as shown in FIGS. 7 to 9 , position restricting portions 18 are further provided within the mounting space 11. The position restricting portions 18 have a porous structure and are provided along the periphery of the receiving groove 13. The position restricting portions 18 contact the liquid guide 2 and the holder 1. The plane on which the bottom of the liquid guide 2 is located is higher than the plane on which the bottom of the position restricting portion 18 is located. The provision of the position restricting portions 18 firstly provides positioning and position restricting functions. This allows the liquid guide 2 to be quickly mounted at the mounting position during mounting, and also prevents the liquid guide 2 from shifting due to external forces. Secondly, the position restricting portions 18 can also function to collect condensed liquid. The atomized liquid forms atomized gas after evaporation, and the atomized gas mixes with air to form an aerosol. The aerosol forms condensed liquid when cooled. If an excessive amount of condensed liquid collects on the inner wall of the holder 1, the condensed liquid is retained by the capillary action of the position restricting portion 18 and is guided back to the liquid guide 2, where it is used after secondary heating and atomization by the heating element 3. This further prevents the condensed liquid from leaking and also improves the utilization rate of the atomization liquid.

[0045] Furthermore, in some preferred embodiments, as shown in FIG. 3 , a liquid storage groove 21 is formed on the ceiling surface of the liquid guide 2, facing the liquid guide port 41. The liquid storage groove 21 is in communication with the liquid guide port 41. A liquid supply surface 23 is formed on the inner wall of the liquid storage groove 21. The liquid guide 2 includes the liquid supply surface 23 and an atomization surface 22 that faces the liquid supply surface 23 and is provided on the opposite side. A heating element 3 is attached to the atomization surface 22. The liquid to be atomized that enters from the first liquid supply port 12 is absorbed and collected within the liquid storage groove 21. When the liquid is guided to the atomization surface 22 through the liquid supply surface 23, it is heated and atomized by the heating element 3. The upper surface of the liquid guide 2 has a shape that fits the gasket 4, and is preferably a flat surface that extends along the cross section of the gasket 4.

[0046] Furthermore, in some preferred embodiments, the liquid guide 2 has a porous structure. The liquid guide 2 can be made of a material having capillary channels or voids, such as synthetic cotton, porous ceramics, glass fiber, porous glass ceramics, porous glass, or other hard or rigid capillary structures. The pores in the liquid guide 2 have a diameter of 0.2 to 200 micrometers. The pores function to guide the liquid to be atomized. Furthermore, because the pores are small, they can form a liquid film and can also retain the liquid in the liquid tank by applying negative pressure. This makes it difficult for the liquid to fall.

[0047] In some preferred embodiments, as shown in FIGS. 1 to 6 , the atomization module further includes an external connection electrode 6. The bottom base 5 has an electrode hole 52. The heater 3 includes a heat generating circuit 31 and electrode connection members 32 extending from both sides of the heat generating circuit 31. The external connection electrode 6 is electrically connected to the electrode connection member 32 through the electrode hole 52. The heater 3 can be formed on the atomization surface 22 of the liquid guide 2 by mounting, printing, vapor deposition, or other methods. The heater 3 can be made of stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, titanium metal, conductive metal fiber yarn, conductive carbon fiber yarn, conductive graphite filament, or other materials. The heat generating circuit 31 may have a conductive track patterned with a meandering or circuitous pattern, and the electrode connection members 32 can be attached to both ends of the heat generating circuit 31. The electrode connection members 32 can be in the form of pads or leads. The electrode connection members 32 are electrically connected to the external connection electrode 6 to supply electricity from a power supply device to the atomization module.

[0048] Furthermore, in some preferred embodiments, the holder 1 has a columnar structure. The holder 1 has a columnar outer shape, preferably a cylindrical structure, so that it can be easily fitted to various liquid storage tanks. This simplifies the development of the finished electronic device and simplifies and facilitates the assembly of the liquid tanks that are combined in the subsequent process, which is advantageous for large-scale mass production.

[0049] The present invention further provides an atomization device. As shown in Figures 10 to 13, the atomization device comprises the above-mentioned Atomization Module and a liquid tank assembly 200. The liquid tank assembly 200 includes a casing 7, a bottom plug 8 provided at the bottom of the casing 7, a liquid tank 9 provided within the casing 7, and an air conduit 10 provided between the casing 7 and the liquid tank 9. The bottom plug 8 has an attachment portion 81 that fits the nebulization module 100. The holder 1 of the nebulization module 100 is inserted into the air conduit 10 through the attachment portion 81 or is covered on the outside of the air conduit 10. Before use, a portion of the nebulization module 100 is exposed to the outside of the bottom plug 8, and the first liquid supply port 12 of the nebulization module 100 is blocked by the inner wall surface of the bottom plug 8. As can be seen, although the liquid tank 9 stores liquid to be nebulized, before use, the liquid guide 2 does not come into contact with the liquid to be nebulized, and the first liquid supply port 12 of the nebulization module 100 is blocked by the sealing portion of the liquid tank assembly 200. At this point, the nebulization liquid and the liquid guide 2 are not in contact with each other. During use, the nebulization module 100 is pushed into the liquid tank assembly 200 until the bottom base 5 of the nebulization module 100 and the bottom of the bottom plug 8 are flush or nearly flush with each other. This exposes the first liquid supply port 12 inside the liquid tank 9, and the nebulization liquid in the liquid tank 9 flows into the first liquid supply port 12 of the nebulization module 100 by gravity. This design is advantageous for transportation, as it can ensure that the nebulization liquid does not leak during transportation. It also avoids the problem of corrosion of the heater 3 due to prolonged contact between the liquid guide 2 and the heater 3 on the liquid guide 2 during storage.

[0050] Furthermore, in some preferred embodiments, a first elastic seal member 201 is provided at the connection point between the nebulization module 100, the air guide tube 10, and the liquid tank 9, and a second elastic seal member 202 is provided at the connection point between the nebulization module 100, the liquid tank 9, and the bottom plug 8. This ensures airtightness and also prevents leakage of nebulization liquid from the connection point.

[0051] Specifically, the first seal 201 can be installed over the outer wall of the air conduit 10. A seal engagement groove 2011 is formed on the outside of the first seal 201. The seal engagement groove 2011 fits into the open end of the ceiling of the holder 1, and the holder 1 engages with the seal engagement groove 2011. The second seal 202 is installed between the bottom plug 8 and the casing 7. A through hole 2021 is formed in advance in the second seal 202 corresponding to the mounting portion 81. The diameter of the through hole 2021 fits into the outer diameter of the holder 1. The holder 1 passes through the through hole 2021 and is connected to the first seal 201 of the air conduit 10. The second seal 202 hermetically connects the nebulization module 100, the liquid tank 9, and the bottom plug 8, and the first seal 201 hermetically connects the nebulization module 100, the air conduit 10, and the liquid tank 9.

[0052] Furthermore, a recess 101 at the bottom of the air conduit 10 forms a step 102. A first seal member 201 is disposed within the recess 101 and is movable in the extension direction of the air conduit 10. The step 102 restricts the position of the first seal member 201. Before use, the holder 1 of the nebulization module 100 engages with the first seal member 201, but the first seal member 201 does not abut against the step 102, and a portion of the nebulization module 100 is exposed to the outside of the bottom plug 8. As a result, the first liquid supply port 12 is blocked by the inner wall of the second seal member 202. During use, on the other hand, an external force is applied to push up the nebulization module 100. The first seal member 201 then moves upward along the air conduit 10 until its position is restricted by the step 102. At this time, the bottom of the atomization module 100 and the bottom of the bottom plug 8 are flush with each other, and the first liquid supply port 12 is exposed inside the liquid tank 9, allowing the atomization liquid in the liquid tank 9 to flow into the first liquid supply port 12 of the atomization module 100 by gravity. This design is advantageous for transportation, as it can ensure that the atomization liquid does not leak during transportation. It also avoids the problem of corrosion of the heater 3 due to long-term contact between the liquid guide 2 and the heater 3 on the liquid guide 2 during storage.
