Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic atomization, and particularly to an atomization assembly and its atomization device.
Background Art
[0002] An electronic atomization device is a device that heats and atomizes a liquid by heating the liquid with electricity, and is currently relatively widely used in the field of electronic cigarettes. Since electronic cigarettes have a similar physical sensation to cigarettes, they have become popular as a new type of tobacco product in recent years. electronic atomizer atomizer As the core member, the atomization core is particularly important. The main part of the atomization core is composed of a liquid guide and a heating element. The liquid guide transmits the liquid to the position of the heating element in order to evaporate the liquid into atomized vapor due to the high temperature when the heating element generates heat. Since the atomization liquid is stored in the liquid storage tank of the atomizer, as the atomization liquid is consumed during the use process, changes occur in the internal space and air pressure of the liquid storage tank. Since the pressure of the liquid at the liquid supply surface of the atomization core changes with the height of the liquid surface, ultimately, there will be a large difference in the pressure of the liquid surface. That is, it is difficult to maintain a balance between the liquid storage tank and Atomizing core Here, the balance mentioned means being able to supply the tobacco liquid required for atomization without liquid leakage. Although the magnitude of the liquid surface pressure changes during use, initially, the liquid surface pressure is large, so a small liquid supply hole is required, and if it is large, liquid leakage will occur. Also, after use, the liquid surface drops and the pressure decreases. At this time, if the liquid supply port is not large enough, the liquid cannot be supplied, resulting in the core burning, but the size of the liquid supply port cannot be changed Therefore The change in the liquid surface pressure causes problems in liquid supply in the atomization core. As a result, a problem of insufficient atomization liquid on the atomization surface is caused, and as the temperature of the heating element continues to rise, a problem of the core burning occurs.

[0018] The present invention provides the following beneficial effects.

Because this gap is small, the tension of the atomizing liquid creates a capillary action between the pressure-stable gap. This is equivalent to having capillary tension. The capillary tension is only affected by the pressure-stable gap. In other words, the pressure-stable tube and holderIf the gap with [object] does not change, the capillary force does not change. In this case, the pressure of the liquid surface at the liquid supply port of the atomization core will not change due to the height of the liquid surface in the liquid storage tank. And, by forming a capillary force in the gap between the pressure stabilizing tube and the holder, the atomization liquid cannot leak from the small ventilation holes due to the capillary force. After the atomization liquid in the liquid storage tank is consumed, when the air pressure in the liquid storage tank changes, the ventilation holes will become a path for air to enter the liquid storage tank, and the gas in the atomization core can enter the pressure stabilizing gap through the ventilation holes. That is, only when the air in the liquid storage tank becomes lower than a certain value compared to the external air pressure can the air break the liquid film of the ventilation holes. Therefore, the provision of the ventilation holes in the pressure stabilizing tube also contributes to the stability of the pressure value when gas enters the liquid storage tank. As described above, a stable liquid supply and ventilation effect are guaranteed.

[0025] Figures 1 to 12 show atomization assemblies in several preferred embodiments of the present invention. The atomization assembly is provided in the liquid storage tank of the electronic atomizer. The atomization assembly includes a hollow holder 10 and an atomization core 20 provided within the holder 10. The atomization core 20 includes a guide fluid 21 and a heating element 22 that is in close contact with or fitted to the guide fluid 21. The guide fluid 21 may be a guide fluid cotton or a porous ceramic guide fluid. The holder 10 is used to provide support and mounting space. The holder 10 primarily serves to mount and fix the guide fluid 21 and the heating element 22. Therefore, it is necessary to have a certain level of support strength to prevent deformation of the guide fluid 21 and the heating element 22 due to external forces and to avoid poor contact between them, thereby avoiding any impact on the atomization effect. at least one Liquid supply port 11 and at least oneA ventilation hole 12 is provided. The liquid supply hole 11 is used to supply liquid to the guide liquid 21. The ventilation hole 12 is also designed to facilitate the transmission of atomizing liquid by balancing the air pressure inside and outside the holder 10, by allowing gas from inside the holder 10 to be introduced into the liquid storage tank when the liquid in the storage tank is consumed and a change in air pressure occurs inside the storage tank. The ventilation hole 12 is provided above the liquid supply hole 11. Furthermore, the size of the ventilation hole 12 must be smaller than the size of the liquid supply hole 11. This prevents leakage of atomizing liquid from the ventilation hole 12. There may be one liquid supply hole 11, or there may be multiple liquid supply holes, preferably multiple. Multiple liquid supply holes 11 are provided at regular intervals along the circumferential direction of the outer wall of the holder 10. By controlling the size of the liquid supply holes 11, it is possible to control the contact area between the atomizing liquid and the guide liquid 21, and thereby control the liquid supply speed. The ventilation opening 12 may be one or multiple, preferably multiple. The multiple ventilation openings 12 are arranged at intervals along the circumferential direction of the outer wall of the holder 10.
[0026] The atomizing assembly in the present invention further includes a pressure stabilizing tube 30. The pressure stabilizing tube 30 covers the outer wall of the holder 10 and shields the liquid supply hole 11 and the ventilation hole 12. Shielding here means that the liquid supply hole 11 and the ventilation hole 12 are not directly exposed into the storage space of the liquid storage tank, but rather the pressure stabilizing tube 30 is placed between the liquid supply hole 11 and the ventilation hole 12 and the liquid storage tank. Furthermore, a millimeter-level pressure stabilizing gap 31 is formed between the inner wall surface of the pressure stabilizing tube 30 and the outer wall surface of the holder 10. As a result, both the liquid supply hole 11 and the ventilation hole 12 are blocked by the inner wall surface of the pressure stabilizing tube 30 and located within the pressure stabilizing gap 31. at least one Pressure-stable ventilation opening 32 and at least oneA pressure-stable liquid supply port 33 is provided. A pressure-stable ventilation port 32 communicates with a ventilation hole 12. The ventilation hole 12 is part of the ventilation path that allows air from inside the atomizing core 20 to enter the liquid storage tank. The air flows along the direction of extension of the ventilation path. That is, the gas inside the atomizing core 20 can pass through the ventilation hole 12, enter the pressure-stable gap 31, and then enter the liquid storage tank via the pressure-stable ventilation port 12. Also, the pressure-stable liquid supply port 33 and the liquid supply hole 11 are offset from each other and communicate with each other. Because the pressure-stable gap 31 is small, the tension between the atomizing liquids is in the pressure-stable gap 3 1 It forms a capillary action. This corresponds to having capillary tension. The capillary tension is only affected by the pressure-stable gap 31. In other words, the pressure-stable tube 30 and Holder 10 If the gap between the two remains unchanged, the capillary tension will not change. In this case, the pressure at the liquid level at the liquid inlet of the atomizing core 20 will not change due to the height of the liquid level in the storage tank. Furthermore, the fact that the ventilation hole 12 is located inside the pressure stabilizing pipe 30 also contributes to stabilizing the pressure value when the gas enters the storage tank.
[0027] In this specific embodiment, the pressure-stable liquid inlet 33 is provided at the bottom of the side wall of the pressure-stable tube 30. Furthermore, the position of the liquid inlet 11 is higher than that of the pressure-stable liquid inlet 33. When atomizing liquid permeates into the pressure-stable gap 31, which includes a fine slit, the liquid rises or seeps in along the pressure-stable gap 31. In this permeation state, the liquid rises higher the narrower the slit. Therefore, providing the pressure-stable liquid inlet 33 at the bottom of the side wall of the pressure-stable tube 30 is advantageous for allowing the atomizing liquid in the storage tank to enter the pressure-stable gap 31 and for quickly and easily permeating the pressure-stable gap 31. Additionally, the position of the liquid inlet 11 being higher than that of the pressure-stable liquid inlet 33 is advantageous for ensuring capillary action. As a result, the atomizing liquid moves upward according to capillary force and enters the inside of the atomizing core 20 through the liquid supply hole 11.
[0028] In a specific embodiment, the pressure-stabilizing ventilation opening 32 is provided on the upper part of the side wall of the pressure-stabilizing pipe 30. This design is advantageous for exposing the pressure-stabilizing ventilation opening 32 above the liquid storage tank after the atomizing liquid in the storage tank has been consumed. As a result, air entering through the ventilation hole 12 can easily enter the upper space in the liquid storage tank where there is no atomizing liquid through the pressure-stabilizing ventilation opening 32.
[0029] In a specific embodiment, the liquid supply port 11 is provided along the circumferential direction of the outer wall surface of the holder 10. Correspondingly, the pressure-stable liquid supply port 33 is provided along the circumferential direction of the outer wall surface of the pressure-stable tube 30. Such a design is advantageous for the atomizing liquid to rapidly enter the pressure-stable gap 31 from the pressure-stable liquid supply port 33 and rapidly be introduced into the guide liquid 21 from the liquid supply port 11. Furthermore, preferably, in order to guide the liquid more quickly and smoothly, the pressure-stable liquid supply port 33 and the liquid supply port 11 overlap in the vertical projection. In the present invention, in the vertical projection, one pressure-stable liquid supply port 33 may be provided so as to overlap one liquid supply port 11, or multiple liquid supply ports 11 may be provided so as to overlap in the vertical projection. Alternatively, multiple pressure-stable liquid supply ports 33 may be provided so as to overlap one liquid supply port 11 in the vertical projection. Alternatively, in the vertical projection, multiple pressure-stable liquid supply ports 33 may be arranged to overlap with multiple liquid supply holes 11. The ventilation holes 12 are provided along the circumferential direction of the outer wall surface of the holder 10. Correspondingly, the pressure-stable ventilation openings 32 are provided along the circumferential direction of the outer wall surface of the pressure-stable pipe 30. Such a design is advantageous for the air inside the atomizing core 20 to rapidly enter the pressure-stable gap 31 from the ventilation holes 12 and to be rapidly introduced into the liquid storage tank from the pressure-stable ventilation openings 32.
[0030] In specific embodiments, since capillary force is related to the size of the pressure-stable gap 31, it is preferable that the pressure-stable gap 31 between the inner wall surface of the pressure-stable tube 30 and the outer wall surface of the holder 10 is smaller than 1 mm. In the immersion state, the narrower the pressure-stable gap 31, the higher the liquid rises. This means that the atomizing liquid rises against gravity due to the difference between cohesive force and adhesive force within the pressure-stable gap 31, allowing it to smoothly pass through the liquid supply hole 11 and enter the atomizing core 20. The design of the gap size allows for smoother liquid guidance in the atomizing assembly.
[0031] In this specific embodiment, the diameter of the liquid supply hole 11 is larger than the diameter of the ventilation hole 12. With this design, the atomizing liquid enters the atomizing core 20 from the liquid supply hole 11 due to capillary action. Furthermore, due to capillary action, the atomizing liquid cannot leak out from the small ventilation hole 12.
[0032] In specific embodiments, the liquid supply port 11, ventilation port 12, pressure-stable liquid supply port 33, and pressure-stable ventilation port 32 may be curved holes, straight holes, or holes that combine curves and straight lines, and are not specifically limited.
[0033] In specific embodiments, the diameter of the ventilation holes 12 is 0.5 mm or less. This further ensures that when using atomizing liquid of a general standard, leakage from the small ventilation holes 12 due to capillary action is prevented. The size of the ventilation holes 12 is mainly determined by the viscosity and surface tension values of the atomizing liquid. The diameter of the liquid supply holes 11 is 1 to 4 mm. This further ensures that atomizing liquid of a general standard enters smoothly through the liquid supply holes 11 due to capillary action. The size of the liquid supply holes 11 is mainly determined according to the differences in viscosity and surface tension of the atomizing liquid. Differences in viscosity and surface tension of the atomizing liquid affect the diameter range of the liquid supply holes 11.
[0034] In a specific embodiment, as shown in Figures 1 to 6, the holder 10 has a cylindrical structure, and the pressure-stabilizing tube 30 has a tubular structure with smaller ends and a larger center. In other words, the holder 10 does not change in size from top to bottom, making it easy to manufacture. On the other hand, the inner diameter of both ends of the pressure-stabilizing tube 30 is approximately the same as or slightly larger than the inner diameter of the holder 10. The central part of the pressure-stabilizing tube 30 may also have a columnar structure. Furthermore, the inner diameter of this central part is larger than the outer diameter of the holder 10. As a result, both ends of the pressure-stabilizing tube 30 are covered by the holder 10 so as to seal the gap. Furthermore, a gap is maintained between the inner wall surface at the central position of the pressure-stabilizing tube 30 and the outer wall surface of the holder 10, and this gap forms a pressure-stabilizing gap 31. This makes it easy to assemble the atomizing assembly and ensures a stable liquid supply effect and ventilation effect.
[0035] In a specific embodiment, as shown in Figures 7 to 12, the pressure-stabilizing tube 30 has a cylindrical structure, and the holder 10 has a tubular structure that is larger at both ends and smaller in the center. In the central region of the holder 10, a mounting portion 13 that fits the pressure-stabilizing tube 30 is formed as a recess. The liquid supply hole 11 and the ventilation hole 12 are provided in the mounting portion 13. Mounting steps 131 are also provided at both ends of the mounting portion 13. The inner diameter of the pressure-stabilizing tube 30 is approximately the same as the outer diameter of both ends of the holder 10. Furthermore, since the mounting steps 131 fit both ends of the pressure-stabilizing tube 30, both ends of the pressure-stabilizing tube 30 are sealed and connected to the mounting steps 131. In addition, a pressure-stabilizing gap 31 is formed between the inner wall surface of the pressure-stabilizing tube 30 and the inner wall surface of the mounting portion 13. By designing it in this way, the atomizing assembly has a columnar appearance, and since there are no protruding parts to the outside as a whole, it looks better. Furthermore, it is easy to assemble and use, and a stable liquid supply and ventilation effect is guaranteed.
[0036] In a specific embodiment, the liquid supply hole 11 is provided in accordance with the guide liquid 21. The guide liquid 21 has a liquid supply surface 211 formed on the surface corresponding to the holder 10. The guide liquid 21 also has an atomizing surface 212 formed on the surface corresponding to the heating element 22. A hollow airflow path A is formed within the guide liquid 21. The guide liquid 21 is used to transfer the atomizing liquid on the liquid supply surface 211 to the atomizing surface 212. The heating element 22 atomizes the atomizing liquid on the inner surface of the guide liquid 21 to form atomized vapor. The atomized vapor mixes with air to form an aerosol, which is discharged through the hollow airflow path A of the holder 10. The ventilation hole 12 is provided so as to be higher than the guide liquid 21 and communicates with the airflow path A. This design makes it difficult for the atomizing liquid to leak from the ventilation hole 12, while allowing air in the airflow path A to easily enter the liquid storage tank from the ventilation hole 12.
[0037] In a specific embodiment, the heating element 22 includes a heating circuit 221 and electrode lead wires 222 extending from both ends of the heating circuit 221. The heating circuit 221 is in close contact with or fitted to the guide liquid 21. The heating circuit 221 is on the atomizing surface of the guide liquid 21. 212 The atomizing liquid above Heat The electrode lead wires 222 are used to heat the heating circuit 221 by connecting to the electrodes and supplying electricity to the heating circuit 221. The atomizing assembly further includes a fixing plug 40 provided at the bottom of the holder 10 for fixing the electrode lead wires 222. The fixing plug 40 may have an insertion hole for inserting the electrode lead wires 222. Alternatively, the outer wall surface of the fixing plug 40 may be provided with a locking groove that fits the electrode lead wires 222 to fix the electrode lead wires 222. This prevents the electrode lead wires 222 from swinging due to external forces and avoids poor contact between the heating element 22 and the guiding fluid 21. Furthermore, the fixing plug 40 has an air intake port. This allows outside air to enter the atomizing assembly from the air intake port.
[0038] The atomizing assembly of the present invention has the following effects. Specifically, small ventilation holes 12 are formed in the holder 10 of the atomizing core 20, and the atomizing core 20 of A pressure stabilizing tube 30 is added to the outside of the holder 10, and the pressure stabilizing tube 30 Holder 10 By covering the outside of it, the pressure stabilizing pipe 30 and Holder 10 A pressure-stable gap 31 is formed between them. Because this gap is small, the tension between the atomizing liquids is in the pressure-stable gap 3 1 It forms a capillary action. This corresponds to having capillary tension. The capillary tension is only affected by the pressure-stable gap 31. In other words, the pressure-stable tube 30 and Holder 10 If the gap between the two remains unchanged, the capillary tension will not change. In this case, the pressure at the liquid level at the liquid inlet of the atomizing core 20 will not change due to the height of the liquid level in the storage tank. Furthermore, because a capillary action force is formed in the gap between the pressure stabilizing tube 30 and the holder 10, the atomizing liquid will not leak out of the small ventilation hole 12 due to the capillary action force. After the atomizing liquid in the storage tank is consumed, when the air pressure inside the storage tank changes, the ventilation hole 12 becomes a path for air to enter the storage tank, and the gas in the atomizing core 20 can enter the pressure stabilizing gap 31 by passing through the ventilation hole 12. In other words, the air can only break the liquid membrane in the ventilation hole 12 when the air inside the storage tank becomes a certain value lower than the external air pressure. Therefore, providing the ventilation hole 12 inside the pressure stabilizing tube 30 also contributes to the stabilization of the pressure value when the gas enters the storage tank. As a result, stable liquid supply and ventilation effect are guaranteed.
[0039] The present invention further provides an atomizing device. As shown in Figures 13 to 16, the atomizing device includes a casing 50, an atomizing assembly 60 provided inside the casing 50, an upper sealing member 70 and a sealing seat 80 provided above and below the atomizing assembly 60, and a bottom base 90 provided at the bottom of the sealing seat 80 and connected to the casing 50. The upper sealing member 70 and the sealing seat 80 are used to seal the atomizing assembly 60 and prevent liquid leakage. A sealed liquid storage tank 100 is formed between the atomizing assembly 60, the casing 50, and the sealing seat 80. Atomizing liquid is stored in the liquid storage tank 100. A pressure-stable liquid supply port 33 of the atomizing assembly 60 communicates with the liquid storage tank 100. A pressure-stable ventilation port 32 also communicates with the liquid storage tank 100. When the storage tank is full of atomizing liquid, the atomizing liquid enters the atomizing assembly 60 along the liquid supply path B. That is, the atomizing liquid enters the pressure-stable gap 31 from the pressure-stable liquid supply port 33, and then enters the atomizing core 20 from the liquid supply hole 11. In this case, as long as the pressure-stable gap 31 between the pressure-stable tube 30 and the atomizing core 20 does not change, the capillary tension does not change. Therefore, in this case, the pressure at the liquid level in the liquid supply hole 11 of the atomizing core 20 does not change due to changes in the liquid level in the storage tank 100, and the liquid supply to the atomizing assembly 60 becomes stable. When the atomizing assembly 60 starts operating, the generated heat heats the atomizing liquid to its boiling point and evaporates it, becoming atomized vapor. This mixes with air to form an aerosol, which is finally drawn in. When the atomizing liquid in the storage tank 100 is consumed, the air in the atomizing core 20 ventilates along the direction of extension of the ventilation path C. That is, after flowing from the ventilation hole 12 into the pressure-stabilizing gap 31, it enters the storage tank 100 through the pressure-stabilizing ventilation opening 32. The fact that the ventilation hole 12 is located inside the pressure-stabilizing pipe 30 also contributes to stabilizing the pressure value when the gas enters the storage tank 100, thereby ensuring stable ventilation.
[0040] Furthermore, preferably, an airflow tube 51 extends inward from the casing 50. The upper sealing member 70 covers the bottom of the airflow tube 51. The upper sealing member 70 also has a locking groove 71, and the top portion of the holder 10 in the atomizing assembly 60 is sealed and locked into the locking groove 71. By providing the upper sealing member 70, leakage of the atomizing liquid from the storage tank 100 from the connection point between the holder 10 and the airflow tube 51 is avoided, thus avoiding any impact on the vaping experience. The airflow tube 51 also communicates with the atomizing core 20. This makes it possible to allow the aerosol generated in the atomizing core 20 to flow out through the airflow tube 51 and ultimately be inhaled.
