Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes and atomization technology, and in particular to an electronic atomization device. Background Technology

[0002] Existing electronic atomizing devices typically employ a single e-liquid tank and a single coil, resulting in limited flavor options and an inability to adjust the overall taste. Furthermore, large-capacity e-liquid tanks are prone to generating negative pressure during continuous vaping, leading to poor e-liquid delivery or even coil burn. Traditional soft cotton cord e-liquid delivery systems are also prone to deformation during assembly and do not fit tightly with the atomizer base, making them susceptible to leakage.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0048] I. For overall structure and shell components, please refer to... Figures 1 to 4 The electronic atomizing device provided by this utility model includes a housing assembly, which consists of a first housing 2 and a second housing 27 that are interlocked. The first housing 2 and the second housing 27 enclose an internal receiving space and an airflow channel. A nozzle 4 is installed at the top of the housing assembly, and the nozzle 4 has an air outlet that communicates with the airflow channel. To prevent condensate from being drawn into the user's mouth, an oil-absorbing cotton 6 is provided inside the nozzle 4.

[0049] II. Inside the first atomizing component and its oil supply system, a second atomizing component and a first atomizing component are sequentially arranged from upstream to downstream along the airflow direction. The first atomizing component is located on the side closest to the nozzle 4.

[0050] like Figure 2 and Figure 4 As shown, the first atomizing assembly includes a first atomizing base 7 and a first heating element 9 disposed within the first atomizing base 7. To ensure sealing, the top of the first atomizing base 7 is provided with a first sealing member 5, and the bottom is provided with a second sealing member 10, for sealing the connection interface between the first atomizing base 7 and the housing assembly and other components.

[0051] A large-capacity main liquid storage tank 24 is provided on one side of the first atomizing component. The main liquid storage tank 24 is sealed by an oil bottle sealing silicone 23, an oil bottle lower silicone 25, and an oil bottle bottom cap 26. The atomizing matrix in the main liquid storage tank 24 is introduced into the first atomizing seat 7 through a hollow liquid guide 21 for atomization by the first heating element 9.

[0052] The hollow liquid guiding component 21 has a columnar structure and extends laterally through the side wall of the first atomizing seat 7. One end of the hollow liquid guiding component 21 extends into the main liquid storage chamber 24, and the other end extends into the first atomizing seat 7 and abuts against the first heating element 9. A through-hole for air pressure balance is formed along the length of the axis of the hollow liquid guiding component 21. This air pressure balance hole connects the internal space of the main liquid storage chamber 24 and the internal space of the first atomizing seat 7 to balance air pressure and assist in oil guiding. The hollow liquid guiding component 21 is preferably made of a mixture of high-hardness polyethylene (PE) and polyethylene terephthalate (PET) fibers.

[0053] To secure the hollow liquid guide 21, a limiting and holding member 22 is also provided on the first atomizing seat 7. The limiting and holding member 22 presses tightly against the position where the hollow liquid guide 21 passes through the first atomizing seat 7, applying a squeezing force to the hollow liquid guide 21 in the direction of the first heating element 9 to maintain close contact between the two and prevent side leakage.

[0054] III. Figure 1 and Figure 4 As shown, the second atomizing component is located below the first atomizing component, and includes a second atomizing base 16 and a second heating element 13 fixed within the second atomizing base 16. The second atomizing component has an oil supply system independent of the main liquid storage tank 24, and adopts a direct filling structure with oil storage cotton.

[0055] Specifically, the self-storing liquid unit is an oil-storing cotton 11, which is installed inside the second atomizing seat 16. The second heating element 13 is directly disposed inside the oil-storing cotton 11 or in close contact with the oil-storing cotton 11. The atomizing matrix is ​​directly injected into and stored in the oil-storing cotton 11, and the oil-storing cotton 11 directly supplies oil to the second heating element 13 for atomization, without the need for conduction through other media.

[0056] In addition, to address the common condensate leakage problem in electronic atomizing devices, a bottom oil-absorbing cotton 15 is installed at the bottom of the second atomizing base 16. The bottom oil-absorbing cotton 15 functions similarly to the top nozzle oil-absorbing cotton 6, primarily to absorb condensate generated and falling back during atomization, or to absorb excess atomized liquid that has not been fully atomized, preventing liquid from accumulating at the bottom of the device under gravity and flowing out of the air inlet or contaminating the internal circuit components. The bottom of the second atomizing assembly is sealed and fixed by a lower silicone sealant 14.

[0057] IV. A battery 28 is vertically installed inside the circuit control and airflow regulation device. A main control circuit board 3 is provided on one side of the first atomizing component and the second atomizing component, and a trigger switch 1 electrically connected to the main control circuit board 3 is provided on the surface of the housing component. The electronic atomizing device is configured such that the main control circuit board 3 controls the first heating element 9 and the second heating element 13 to work independently or simultaneously according to the signal from the trigger switch 1, thereby generating atomized gas with a single flavor or a mixed flavor in the airflow channel.

[0058] The device has an airflow regulating assembly at the bottom, including an air regulating seat 19 fixed at the air inlet and an air regulating rod 20 movably mounted on the air regulating seat 19. The user can adjust the air intake volume by moving the air regulating rod 20.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
