Description

Atomization assembly and electronic atomization device Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to an atomization assembly and an electronic atomization device thereof. Background Art

[0002] An electronic atomizer uses electricity to heat a liquid and turn it into a vapor. The atomizer core, as the core of the device, is particularly important. It consists of a liquid guide and a heating element. The liquid guide conducts the liquid to the heating element, where the high temperature of the heating element evaporates the liquid into vaporized steam.

[0003] As the atomized liquid in the liquid storage tank is consumed during use, the air pressure in the space inside the liquid storage tank will change. This is because the liquid pressure at the liquid guide port of the atomizer core will change with the liquid level height. As a result, there is a large difference in the final liquid level pressure, which makes it difficult to maintain a balance between the liquid storage tank and the atomizer core. Initially, the liquid level pressure is high, and a small liquid guide port is required to meet the liquid supply demand. A larger port will cause oil leakage. After use, the liquid level drops and the pressure decreases. At this time, a large-aperture liquid inlet is required, otherwise the liquid will not be supplied and the core will be stuck. However, the size of the liquid inlet does not change. Because the change in liquid level pressure will cause problems with the liquid supply to the atomizer core, there will be a lack of atomized liquid at the atomizing surface. The temperature of the heating element will continue to rise, thus causing the core to stick.

[0004] When the liquid storage tank is a flowing liquid, the atomized liquid itself will absorb gravity and flow to a lower place. As the atomized liquid is consumed, the external environment changes, the temperature changes, the fluidity of the atomized liquid changes, etc., the gravity will also change. Considering that the electronic atomization device will be in different directions when carried, this will easily lead to leakage of the atomized liquid, and the leakage of the atomized liquid will cause battery failure and contaminate clothes at the same time. Therefore, better anti-leakage performance is needed, so a more convenient and compact assembly structure and better anti-leakage performance are needed. Summary of the Invention

[0036] 1 to 11 show an atomization assembly in some preferred embodiments of the present invention, where the atomization assembly is disposed in a liquid storage tank of an electronic atomization device. The atomizer assembly includes an inner bracket 10 with a hollow structure and an atomizer core 20 arranged in the inner bracket 10. The atomizer core 20 includes a guide liquid 21 and a heating element 22 that is attached to or embedded with the guide liquid 21. It can be understood that the inner bracket 10 is used to provide support and installation space for the guide liquid 21 and the heating element 22, and plays the role of installing and fixing the guide liquid 21 and the heating element 22. Therefore, it needs to have a certain supporting strength to prevent the guide liquid 21 and the heating element 22 from being deformed by external forces, avoid poor contact between the two, and thus avoid affecting the atomization effect. A liquid guide port 11 is provided on the inner bracket 10 to guide the liquid 21. The atomized liquid enters the atomizer core 20 through the liquid guide port 11. In the present invention, the guide liquid 21 can be porous ceramic, liquid guide cotton, or a combination of the two liquid guide materials. The guide liquid 21 is used to conduct the atomized liquid to the position of the heating element 22 for heating. When the heating element 22 is heated, the high temperature of the heating element 22 evaporates the liquid into atomized steam.

[0037] The atomization assembly also includes an outer bracket 40 that is sleeved on the outside of the inner bracket 10 and corresponding to the atomization core 20. A smaller inner tank space is formed between the inner wall surface of the outer bracket 40 and the outer wall surface of the inner bracket 10. The tension between the atomized liquid will form a capillary phenomenon in the inner tank space, which is equivalent to a capillary tension. The capillary tension is only affected by the inner tank space. That is to say, when the gap between the outer bracket 40 and the inner bracket 10 remains unchanged, the capillary tension is unchanged. At this time, the liquid level pressure of the liquid guide port 11 of the inner bracket 10 will no longer change due to the liquid level in the liquid storage tank. When the liquid storage tank contains a flowing liquid, the atomized liquid itself will absorb gravity and flow downward. However, as the atomized liquid is consumed, the external environment changes, the temperature changes, and the fluidity of the atomized liquid changes, the gravity will also change. Therefore, the inner tank space of the present invention is filled with an oil control member 30, which covers the liquid guide port 11 of the inner bracket 10. That is, the liquid guide port 11 of the inner bracket 10 is arranged within the coverage area of ​​the oil control member 30, so that the oil control member 30 can better buffer the pressure at the liquid guide port 11 and better guide the liquid 21 through the liquid guide port 11. Here, the height of the oil control member 30 can be greater than the height of the liquid guide port 11 of the inner bracket 10; the fiber or porous structure of the oil control member 30 reduces the pressure of the liquid and reduces its fluidity, and can also reduce the force of the atomized liquid flowing downward due to its own gravity. When the liquid in the guide liquid inside the atomizer core 20 becomes less, the atomized liquid on the oil control member 30 is absorbed by the capillary tension between the micropores, thereby achieving the purpose of smooth liquid supply without easy leakage.

[0038] The oil control member 30 here can be made of cotton material, or can be an elastic fiber composed of fiber filaments, or a porous structure similar to a sponge. Its function is to reduce the pressure of the liquid and reduce its fluidity through its fiber or porous structure. It can also reduce the force of the atomized liquid flowing downward due to its own gravity, and can control the liquid from continuing to leak. When the guide liquid of the internal atomization core 20 needs atomized liquid, it can absorb the atomized liquid from the oil control member 30. The purpose of this is to prevent the leakage of the atomized liquid and at the same time ensure the supply of the atomized liquid.

[0039] The atomizer assembly provided by the present invention adds an outer bracket 40 to the outside of the inner bracket 10 of the atomizer core 20, and forms an inner tank space between the inner wall surface of the outer bracket 40 and the outer wall surface of the bracket. This inner tank space is relatively small, and the liquid pressure in the liquid storage tank is stabilized by the inner tank space; the oil control component 30 fills the gap, and the oil control component 30 uses its fiber or porous structure to reduce the pressure of the liquid and reduce its fluidity, thereby reducing the force of the liquid flowing downward due to its own gravity. It can reduce the leakage of the atomized liquid, and when the liquid in the liquid guide 21 in the inner bracket 10 becomes less, the atomized liquid on the oil control component 30 can be absorbed by the capillary tension between the micropores, so that the liquid can be supplied smoothly.

[0040] The outer bracket 40 is provided with a liquid inlet hole 41 for guiding liquid to the oil control component 30, and the atomized liquid in the outer liquid storage tank enters the atomization component through the liquid inlet hole 41; in order to ensure that the liquid in the electronic atomization device can be consumed smoothly, at least part of the liquid inlet hole 41 is arranged at the lower position of the outer bracket 40, especially the lowermost position.

[0041] In a specific embodiment, as shown in Figures 1 and 2, the liquid inlet holes 41 are arranged at upper and lower positions along the circumference of the outer wall surface of the outer bracket 40, that is, the liquid inlet holes 41 provided on the outer bracket 40 are distributed up and down, and the liquid inlet holes 41 can also be evenly arranged at upper, middle and lower positions along the circumference of the outer wall surface of the outer bracket 40, so as to ensure uniform and rapid infiltration of the oil control part 30 and achieve a better liquid guiding effect.

[0042] Controlling the size of the liquid inlet hole 41 can control the contact area between the atomized liquid and the oil control component 30, and thus control the liquid inlet rate; in some embodiments, the liquid inlet hole 41 can be a straight hole, a curved hole or a combination thereof, such as a circular hole, an elliptical hole, an inverted T-shaped or I-shaped structure, without specific limitation; as shown in Figures 4, 8-11, in a specific embodiment, the liquid inlet hole 41 is an inverted T-shaped or I-shaped structure, so that the liquid inlet efficiency is relatively fast, and this vertical liquid inlet part can allow the liquid to be quickly replenished to the oil control component 30. At the same time, the liquid inlet area of ​​the vertical liquid inlet part is also smaller in this design, which can prevent leakage.

[0043] In a specific embodiment, one or more liquid guide ports 11 may be provided, preferably multiple. Multiple liquid guide ports 11 are regularly spaced along the circumference of the outer wall of the inner bracket 10. Controlling the size of the liquid guide ports 11 can control the contact area between the oil control member 30 and the liquid guide body 21, thereby controlling the liquid inlet rate. Preferably, the liquid guide ports 11 are spaced circumferentially around the outer wall of the liquid guide body 21, with the liquid guide ports 11 positioned in the middle of the liquid guide body 21. This ensures uniform and rapid wetting of the oil control member 30, achieving a better liquid guide effect.

[0044] As shown in FIG1 , in the present invention, the diameter of the liquid guide port 11 on the inner bracket 10 needs to be relatively large to ensure that the contact area between the liquid guide body 21 and the oil control member 30 is large enough to meet the liquid supply demand. In addition, the large diameter of the liquid guide port 11 allows the two end portions of the liquid guide body 21 to function as ventilation ports 11. Preferably, the liquid guide area of ​​all liquid guide ports 11 is at least one-fourth of the area of ​​the liquid guide body 21, so that the liquid guide body 21 and the oil control member 30 have sufficient contact area, and the liquid guide body 21 can absorb the atomized liquid on the oil control member 30 through the liquid guide port 11.

[0045] In some embodiments, as shown in FIG7 , the inner bracket 10 comprises, from top to bottom, an upper mounting portion 12, an intermediate mounting portion 13, and a lower mounting portion 14. An outer bracket 40 is mounted on the intermediate mounting portion 13. The outer diameters D1 and D2 of the upper mounting portion 12 and the lower mounting portion 14 are both smaller than the outer diameter D3 of the intermediate mounting portion 13. Because the atomizer core 20 is mounted within the electronic atomizer device, to prevent leakage, the mounting area of ​​the atomizer core 20 is typically sealed with an elastic material (such as silicone or rubber) between the outer periphery of the atomizer core 20 and the electronic atomizer device. Specifically, the atomizer assembly and other components of the electronic atomizer device are mounted at the upper mounting portion 12 and the lower mounting portion 14, while the outer bracket 40 at the intermediate mounting portion 13 is located within the liquid reservoir. This does not increase the overall assembly space of the electronic atomizer device, making the overall structure of the electronic atomizer device more compact and facilitating a thinner and lighter design.

[0046] In a specific embodiment, as shown in Figure 1, the inner bracket 10 is a cylindrical structure, and a liquid guide port 11 is provided at a circumferential interval in the middle position of the inner bracket 10. The size of the inner bracket 10 is constant from top to bottom, and it is easy to produce; the outer bracket 40 is a tubular structure that is slightly smaller at both ends and larger in the middle, and the oil control member 30 is a cylindrical structure that matches the outer bracket 40; the inner diameters of the two ends of the outer bracket 40 are basically the same as or slightly larger than the inner diameter of the inner bracket 10, and the middle part of the outer bracket 40 can be a columnar structure, and the inner diameter of the middle part is larger than the outer diameter of the inner bracket 10, so that the two ends of the outer bracket 40 can be gap-sealed and sleeved on the inner bracket 10, and a gap is formed between the inner wall surface of the middle position of the outer bracket 40 and the outer wall surface of the inner bracket 10, and the cylindrical structure of the oil control member 30 is placed in the gap. The oil control member 30 can be specifically fiber cotton, which is used to control the impact of the atomized liquid on the guide liquid 21 of the inner atomizing core 20, and to slow down the force of the atomized liquid leaking to a lower place due to its own gravity.

[0047] In a specific embodiment, the distance between the inner wall surface of the outer bracket 40 and the outer wall surface of the inner bracket 10 is less than 1 mm. On the one hand, by controlling the gap between the two, the thickness of the oil control component 30 is controlled, and the function is to stabilize the liquid pressure in the liquid storage tank through the gap. The oil control component 30 is filled in the gap, further reducing the force of the liquid flowing downward due to its own gravity. When the liquid in the internal liquid guide 21 becomes less, the atomized liquid of the oil control component 30 is absorbed by the capillary tension between the micropores, so as to achieve the purpose of smooth liquid supply without easy leakage.

[0048] As shown in Figures 8 and 11, in a specific embodiment, a ventilation hole 15 is provided on the inner bracket 10 of the atomizer assembly of the present invention. The ventilation hole 15 is provided in the coverage area of ​​the oil control component 30. The ventilation hole 15 is provided in the coverage area of ​​the oil control component 30, so that the oil control component 30 can well buffer the pressure at the ventilation hole 15, thereby achieving a stable ventilation effect; the ventilation hole 15 is set away from the liquid guide 21 and is in air communication with the atomizer core 20. The area of ​​the ventilation hole 15 is smaller than the area of ​​the liquid guide port 11, so that the atomized liquid will not leak from the smaller ventilation hole 15 due to capillary force; it can be understood that the ventilation hole 15 is not blocked by the liquid guide 21 toward the atomizer core 20, so that the hollow part of the atomizer core 20 can be well connected to the oil control component 30 through the ventilation hole 15, and then connected to the external liquid storage tank, thereby playing a ventilation role. When the atomized liquid in the liquid storage tank is consumed, the air in the atomizer core 20 flows into the oil control component 30 through the ventilation hole 15, and then enters the liquid storage tank along the liquid inlet hole 41 through the porous structure of the oil control component 30, thereby ensuring stable ventilation and smooth liquid conduction.

[0049] Furthermore, the ventilation hole 15 can be a separately arranged hole; or the ventilation hole 15 is a hole connected to the liquid guiding port 11, and the ventilation hole 15 is arranged away from the liquid guiding liquid 21, so that air can circulate on both sides of the ventilation hole 15 for ventilation; or the ventilation hole 15 is a gap formed between the edge of the liquid guiding port 11 and the liquid guiding liquid 21, that is, the ventilation hole 15 is a gap formed at the edge when the liquid guiding port 11 is not completely blocked by the liquid guiding liquid 21, and the atomizing assembly is ventilated through the gap when in use.

[0050] In a specific embodiment, as shown in Figures 1 and 5, the heating element 22 includes a heating circuit 221 and electrode leads 222 extending from both ends of the heating circuit 221. The heating circuit 221 is fitted or embedded with the liquid-conducting body 21. The heating circuit 221 is used to heat the atomized liquid on the atomizing surface of the liquid-conducting body 21. The electrode lead 222 is used to connect the electrode to power the heating circuit 221 to heat the heating circuit 221; the atomizing assembly also includes a fixing plug 50 provided at the bottom of the inner bracket 10 and used to fix the electrode lead 222. The fixing plug 50 can be provided with an insertion hole for the electrode lead 222 to pass through, or a slot matching the electrode lead 222 can be provided on the outer wall surface of the fixing plug 50 to fix the electrode lead 222, thereby preventing the electrode lead 222 from shaking due to external force, thereby avoiding poor contact between the heating element 22 and the liquid-conducting body 21; and the fixing plug 50 is provided with an air inlet 51, so that external air can enter the atomizing assembly through the air inlet 51.

[0051] The atomizer assembly provided by the present invention adds an outer bracket 40 to the outside of the inner bracket 10 of the atomizer core 20, and forms an inner tank space between the inner wall surface of the outer bracket 40 and the outer wall surface of the bracket. This inner tank space is relatively small, and the liquid pressure in the liquid storage tank is stabilized by the inner tank space; the oil control component 30 fills the gap, and the oil control component 30 uses its fiber or porous structure to slow down the pressure of the liquid and reduce its fluidity, thereby reducing the force of the liquid flowing downward due to its own gravity. The leakage of the atomized liquid can be reduced, and when the liquid in the liquid guide inside the inner bracket 10 becomes less, the atomized liquid on the oil control component 30 can be absorbed by the capillary tension between the micropores, so that the liquid can be supplied smoothly.

[0052] The present invention also provides an electronic atomization device, as shown in Figures 12 to 15, comprising a shell 60, an atomization assembly 70 arranged in the shell 60, an upper seal 81 and a sealing seat 82 respectively arranged above and below the atomization assembly 70, and a base 90 arranged at the bottom of the sealing seat 82 and connected to the shell 60, the upper seal 81 and the sealing seat 82 are used to seal the atomization assembly 70 to prevent liquid leakage; a closed liquid storage tank 100 is formed between the atomization assembly 70, the shell 60 and the sealing seat 82, and atomized liquid is stored in the liquid storage tank 100, and an upper seal 81 and a sealing seat 82 are arranged above and below the atomization assembly 70, and the outer bracket 40 of the atomization assembly 70 is arranged in the liquid storage tank 100, without increasing the assembly space, so that the overall structure of the electronic atomization device is more compact, which is conducive to the design of the electronic atomization device to be lighter and thinner. When the liquid storage tank 100 is full of atomized liquid, the atomized liquid enters the atomizer assembly 70 through the liquid inlet hole 41 of the outer bracket 40, infiltrates the oil control component 30, and then enters the atomizer core 20 through the liquid guide port 11 of the inner bracket 10. The atomizer assembly 70 starts working, generating heat to heat the atomized liquid to the boiling point, evaporating it into atomized vapor, which mixes with air to form an aerosol, and is finally inhaled.

[0053] Furthermore, it is preferred that an airflow tube 61 is extended inward from the outer shell 60, and an upper seal 81 is sleeved on the bottom of the airflow tube 61. A card slot 811 is provided on the upper seal 81, and the top of the inner bracket 10 of the atomizer assembly 70 is sealed and carded in the card slot 811. The setting of the upper seal 81 prevents the atomized liquid in the liquid storage tank 100 from leaking through the connection between the inner bracket 10 and the airflow tube 61, thereby avoiding affecting the taste experience; the airflow tube 61 is connected to the atomizer core 20, so that the aerosol generated in the atomizer core 20 can flow out from the airflow tube 61 and eventually be inhaled.
