Description

Technical Field

[0001] This utility model relates to the field of electronic atomizer technology, and in particular to a leak-proof electronic atomizer. Background Technology

[0002] Most existing electronic atomizers on the market place the liquid delivery medium and heater in the liquid storage bottle. Therefore, the liquid storage bottle needs to be equipped with a vertical atomization channel that runs through the top and bottom. The atomization matrix heated and atomized by the heater is condensed and the resulting condensate adheres to the inner wall of the atomization channel.

[0003] Existing electronic atomizers typically integrate the liquid delivery medium and heater within a storage bottle and connect it to the atomization channel. This vertical atomization channel structure, which runs through the storage bottle, can easily lead to excessive condensation on the inner wall of the atomization channel, resulting in leakage.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0031] like Figures 1-4As shown, the leak-proof electronic atomizer provided by this utility model includes a housing 1. Inside the housing 1 are a liquid storage bottle 2, an electronic control component 3, an atomizing component 4, and a support platform 5. The electronic control component 3 is electrically connected to the atomizing component 4. The atomizing component 4 includes a heating element 6, an atomizing channel 7, a liquid guiding medium 8, and an airflow sensor 9. The atomizing channel 7 is L-shaped. The support platform 5 has a groove 10 corresponding to the bottom corner of the atomizing channel 7. The bottom of the atomizing channel 7 is located within the groove 10, meaning the bottom corner of the atomizing channel 7 is recessed to ensure it is within the groove 10. The airflow sensor 9 is located at the air inlet of the atomizing channel 7. The liquid storage bottle 2 is connected to the liquid guiding medium 8, which is located at the bottom of the atomizing channel 7. The heating element 6 covers and abuts against the liquid guiding medium 8.

[0032] It is understood that the heating element 6 and the liquid guiding medium 8 are installed within the atomizing channel 7, which is not located in the liquid storage bottle 2. When the user inhales, the airflow sensor 9 detects the inhalation signal. At this time, the heating element 6 operates to heat the atomized liquid on the liquid guiding medium 8. Specifically, the airflow from the air inlet blows onto the surface of the heating element 6, carrying away the vaporized atomized liquid and cooling the heating element 6 to prevent it from overheating and producing a burnt taste. After inhalation, the condensed atomized liquid in the atomizing channel 7 returns to the bottom of the atomizing channel 7 under the influence of gravity, that is, back to the position of the groove 10, so that it can be reused for heating in the next inhalation, avoiding leakage.

[0033] Compared with the prior art, the technical solution of this utility model sets the atomizing channel 7 to be non-vertical, that is, the heater and the liquid guiding medium 8 are set at the bottom of the L-shaped atomizing channel 7. After each atomization, the condensate will return to the groove 10 for the next atomization, thus avoiding the occurrence of leakage. The heater and the liquid guiding medium 8 are set on the support platform 5, which makes the modular design of the product more flexible.

[0034] Furthermore, the bottom of the liquid storage bottle 2 is provided with a liquid outlet 11, the support platform 5 is provided with a liquid channel 12, and a liquid guide tube 13 is provided in the liquid channel 12. One end of the liquid guide tube 13 is connected to the liquid outlet 11, and the other end of the liquid guide tube 13 is connected to the liquid guiding medium 8.

[0035] It is understood that the liquid guide tube 13 can guide the atomizing liquid in the liquid storage bottle 2 onto the liquid guide medium 8, that is, it can supply the atomizing liquid to the liquid guide medium 8.

[0036] Preferably, the bottom of the atomizing channel 7 is provided with a recess 14, the liquid guiding medium 8 is disposed in the recess 14, and the recess 14 is located in the groove 10. When the atomized liquid condensed on the atomizing channel 7 can be returned to the recess 14 by gravity for use in the next suction, the leakage phenomenon is also avoided.

[0037] Furthermore, the cross-section of the liquid guiding medium 8 is trapezoidal, with the higher end of the liquid guiding medium 8 positioned within the corner of the atomizing channel 7, and the lower end positioned at the air inlet facing the atomizing channel 7. It can be understood that the heating element 6 covering the liquid guiding medium 8 is inclined towards the air inlet of the atomizing channel 7. This means that during user inhalation, the inclined heating element 6 experiences better airflow impact, resulting in better heat dissipation and preventing overheating that could lead to a burnt taste. The trapezoidal cross-section of the liquid guiding medium 8 allows it to absorb more atomized liquid, ensuring that each part of the inclined heating element 6 can evenly heat the atomized liquid, resulting in better atomization.

[0038] Preferably, the liquid-conducting medium 8 is a ceramic core. Ceramic cores are made of materials with high porosity, adsorption capacity, flame retardancy, and high temperature resistance, which can achieve better liquid-conducting effect. Of course, this solution can also use a cotton core. When using a cotton core, it needs to be made of a material that has both oil-conducting and oil-storing properties, and the heating element 6 needs to be in close contact with the liquid-conducting medium 8.

[0039] Furthermore, the atomizing channel 7 includes an air intake channel 15 and an exhaust channel 16, wherein the diameter of the air intake channel 15 is smaller than that of the exhaust channel 16. It is understood that when a user inhales, the smoke generated by the heating element 6 flows out through the exhaust channel 16. The smaller diameter of the air intake channel 15 compared to the exhaust channel 16 facilitates the smooth discharge of the smoke.

[0040] Furthermore, the lower end of the liquid guiding medium 8 is lower than the bottom of the air intake channel 15. It should be noted that when the condensed atomized liquid flows back into the recess 14, the lower end of the liquid guiding medium 8 being lower than the bottom of the air intake channel 15 prevents the condensed atomized liquid from flowing into the air intake channel 15.

[0041] Furthermore, the bottom of the liquid guiding medium 8 is fixed to the bottom of the recess 14, and a gap is provided between the periphery of the liquid guiding medium 8 and the sidewall of the recess 14. It can be understood that when the condensed atomized liquid flows back into the recess 14, the gap allows the condensed atomized liquid to flow smoothly into the recess 14, that is, to flow back onto the liquid guiding medium 8.

[0042] Furthermore, the outer casing 1 includes a first chamber 17 for placing the liquid storage bottle 2 and a second chamber 18 for placing the electronic control component 3. The first chamber 17 is located above the second chamber 18, and the support platform 5 is located between the first chamber 17 and the second chamber 18. The liquid storage bottle 2, the electronic control component 3, and the support platform 5 are all assembled in different areas, which is simple in structure, not easy to confuse, easy to assemble, and effectively improves the assembly efficiency.

[0043] Furthermore, the electronic control component 3 includes a battery 19 and a control chip 20. The battery 19 is connected to the control chip 20, and the control chip 20 is connected to the heating element 6 and the airflow sensor 9. When the airflow sensor 9 detects that the user is inhaling, the control chip 20 controls the heating element 6 to heat up, thereby atomizing the atomized liquid.

[0044] In summary, the leak-proof electronic atomizer provided by this utility model allows the condensed atomized liquid in the atomization channel to return to the recessed area under gravity for use in the next vaping session, thus preventing leakage. The trapezoidal cross-section of the liquid guiding medium allows it to absorb more atomized liquid, ensuring that each part of the inclined heating element can evenly heat the atomized liquid, resulting in better atomization. The diameter of the air inlet channel is smaller than that of the exhaust channel, facilitating smooth smoke discharge. The gap and the lower end of the liquid guiding medium are lower than the height of the air inlet channel, preventing condensed atomized liquid from flowing into the air inlet channel. Furthermore, by placing the heater and the liquid guiding medium at the bottom of the L-shaped atomization channel, the condensed liquid returns to the recessed area after each atomization for use in the next atomization, preventing leakage. The heater and the liquid guiding medium are mounted on the support platform, allowing for more flexible modular design.

[0045] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present invention.
