[0036] Next, refer to Figures 1 - 5 Describe the double-row oil guiding hole structure of the electronic atomizer according to the embodiment of the present utility model.

[0037] As Figures 1 - 5 shown, the double-row oil guiding hole structure of the electronic atomizer is mainly applied to high-power electronic atomizer devices, and can also be applied to low-power electronic atomizer devices, meeting the use requirements of different power devices, with better applicability and effectively reducing the production and manufacturing costs.

[0038] Specifically, the double-row oil guiding hole structure of the electronic atomizer includes an oil storage chamber 100 and a double-layer atomization tube structure. A liquid storage cavity 110 and an atomization cavity 120 are arranged in the oil storage chamber 100. Liquid oil is stored inside the liquid storage cavity 110, and the atomization cavity 120 serves as a flow channel for heating and atomizing the oil and is communicated with the suction nozzle 140 of the electronic atomizer.

[0039] The double-layer atomizing tube structure is arranged in the oil storage chamber 100 and is used to separate the oil storage cavity 110 and the atomizing cavity 120, enabling the two cavities to work independently. The double-layer atomizing tube structure includes an outer atomizing tube 210 and an inner atomizing tube 230. The outer atomizing tube 210 serves as the side wall of the oil storage cavity 110, and the inner atomizing tube 230 serves as the channel wall of the atomizing cavity 120. An oil-absorbing cotton 220 is also filled and arranged between the outer atomizing tube 210 and the inner atomizing tube 230. The oil in the oil storage chamber 100 enters the atomizing cavity 120 after entering the oil-absorbing cotton 220.

[0040] Among them, a basic oil guiding hole 211 and a supplementary oil guiding hole 212 are axially arranged on the tube wall of the outer atomizing tube 210. The setting position of the supplementary oil guiding hole 212 is higher than that of the basic oil guiding hole 211. The oil in the oil storage cavity 110 enters the oil-absorbing cotton 220 through the basic oil guiding hole 211 and the supplementary oil guiding hole 212.

[0041] Specifically, the basic oil guiding hole 211 and the supplementary oil guiding hole 212 are set at different heights of the outer atomizing tube 210. The basic oil guiding hole 211 is at the lower part, which meets the oil guiding speed required for general low-power atomization. The supplementary oil guiding hole 212 is at the upper part, which can increase the oil guiding speed and meet the oil guiding speed required for high-power atomization. The oil in the oil storage cavity 110 enters the oil-absorbing cotton 220 through the two oil guiding holes.

[0042] When the electronic atomizer is in the high-power output state, the basic oil guiding hole 211 and the supplementary oil guiding hole 212 can respectively supply oil to the heating component, accelerating the oil guiding speed and improving the oil guiding efficiency. The continuous oil supply capacity is increased, meeting the continuous oil supply amount required by the heating component during high-power output, and obtaining a good taste while generating a large amount of smoke.

[0043] Existing high-power electronic atomizers are prone to excessive oil supply at a relatively fast oil guiding speed. The supply amount is greater than the oil consumption of the heating component during operation. At this time, the excess oil will flow out from the bottom, resulting in oil leakage. In order to achieve both the relatively fast oil guiding speed required for high-power output and prevent the product from leaking oil, the combination of the double-row oil guiding hole structure and the double-layer atomizing tube structure of the present utility model achieves the effect of rapid oil supply without oil leakage. The oil in the oil storage cavity 110 enters the heating component under the action of multiple buffer conductions, ensuring rapid oil supply, meeting the working requirements of high-power electronic atomizers without affecting the smoking taste.

[0044] In some embodiments of the present utility model, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown in the figure, an atomization inner tube 230 is provided with an atomization mesh 310. A wicking cotton 240 is arranged between the atomization mesh 310 and the atomization inner tube 230. The oil liquid in the oil storage cavity 110 contacts the atomization mesh 310 successively through the atomization outer tube 210, the wicking cotton 220, the atomization inner tube 230 and the wicking cotton 240.

[0045] Specifically, the heating component of the present utility model is the atomization mesh 310. The atomization mesh 310 is fixed inside the atomization inner tube 230 through an atomization tube fixing seat 320. The atomization mesh 310 contacts the atomization inner tube 230 through the wicking cotton 240. The oil liquid of the wicking cotton 220 enters the wicking cotton 240 through the atomization inner tube 230. The wicking cotton 240 is of a columnar ring structure. The atomization mesh 310 fits the inner ring of the wicking cotton 240, and the outer ring of the wicking cotton 240 fits the atomization inner tube 230.

[0046] Further, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , at least one set of oil guiding grooves 231 is axially arranged on the side wall of the atomization inner tube 230. The oil guiding grooves 231 are aligned with the position of the atomization mesh 310. The oil guiding grooves 231 are of a through groove structure. The oil liquid of the wicking cotton 220 enters the wicking cotton 240 through the oil guiding grooves 231. In order to improve the oil guiding speed of the oil liquid, the positions of the oil guiding grooves 231 and the atomization mesh 310 match each other. In this embodiment, two sets of atomization meshes 310 of the electronic atomizer are provided, that is, the oil guiding grooves 231 are arranged corresponding to the positions of the two atomization meshes 310, so that the oil liquid of the wicking cotton 220 can directly enter the wicking cotton 240 through the oil guiding grooves 231. The setting position of the supplementary oil guiding hole 212 is aligned with the upper atomization mesh 310, so that the oil liquid can quickly enter above the wicking cotton 220 and then enter the wicking cotton 240 through the oil guiding grooves 231, effectively improving the oil guiding speed.

[0047] Further, as shown in Figure 1 , Figure 4 and Figure 5 , the supplementary oil guiding hole 212 is located within the setting height range of the wicking cotton 240. Specifically, the setting positions of the supplementary oil guiding hole 212 and the basic oil guiding hole 211 are both within the height range of the wicking cotton 240, that is, the height of the wicking cotton 240 can cover the positions of the two oil guiding holes, so that the oil liquid can quickly enter the wicking cotton 240 through the two oil guiding holes.

[0048] In some embodiments of the present utility model, as shown in Figures 1 - 5As shown, the basic oil guiding holes 211 are arranged at equal intervals around the atomizing outer tube 210, and the basic oil guiding holes 211 are arranged close to the bottom area of the oil storage cavity 110. Specifically, the basic oil guiding holes 211 are arranged in the bottom area of the atomizing outer tube 210, so that the oil liquid in the oil storage cavity 110 can still enter the oil absorbing cotton 220 through the basic oil guiding holes 211 in the low liquid level state, improving the utilization efficiency of the oil liquid.

[0049] Further, as Figure 3 shown, the supplementary oil guiding holes 212 are arranged at equal intervals around the atomizing outer tube 210, and the number of the supplementary oil guiding holes 212 is less than that of the basic oil guiding holes 211. Specifically, the position of the supplementary oil guiding holes 212 is higher than that of the basic oil guiding holes 211. When the oil liquid in the oil storage cavity 110 is sufficient, the high-power working state of the electronic atomizer can be supported by sufficient oil liquid. The supplementary oil guiding holes 212 are arranged at the upper position, which can improve the utilization of the upper area of the oil absorbing cotton 220, and the supplementary oil guiding holes 212 lead the oil liquid in the oil storage cavity 110 into the upper area of the oil absorbing cotton 220.

[0050] In this embodiment, the distance between the basic oil guiding holes 211 and the supplementary oil guiding holes 212 is 8 mm to 10 mm. The distance between the two oil guiding holes is less than the height of the oil guiding cotton 240 to ensure the oil guiding effect of the two oil guiding holes.

[0051] In some embodiments of the present utility model, as Figure 3 shown, the aperture of the basic oil guiding holes 211 is equal to that of the supplementary oil guiding holes 212, and the aperture of the basic oil guiding holes 211 is 0.5 mm to 0.7 mm. Specifically, the aperture of the oil guiding holes is adjusted according to the design power and equipment specifications of the electronic atomizer.

[0052] In some embodiments of the present utility model, as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, a condensate cotton 250 is arranged at the top of the oil absorbing cotton 220, and the condensate cotton 250 is arranged in the atomizing outer tube 210 and above the oil absorbing cotton 220. Specifically, the condensate cotton 250 is used to adsorb the excess condensate oil generated by atomization to prevent the oil liquid from being sucked into the mouth.

[0053] Further, as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, an oil separation silica gel 260 is arranged between the condensate cotton 250 and the oil absorbing cotton 220, and the oil separation silica gel 260 is used to separate the condensate cotton 250 and the oil absorbing cotton 220, so that the condensate cotton 250 is kept in a dry state and the oil liquid of the oil absorbing cotton 220 is prevented from entering the condensate cotton 250.

[0054] In some embodiments of the present utility model, such as Figure 1 , Figure 2 and Figure 4 shown, it further includes a bottom sealing silica gel 130 at the bottom of the sealed oil tank 100 and a suction nozzle 140 at the bottom of the sealed oil tank 100. The suction nozzle 140 and the bottom sealing silica gel 130 are technical solutions well-known to those skilled in the art and will not be described in detail in this embodiment.

[0055] Working principle of the electronic atomizer of the present utility model:

[0056] The oil liquid is stored in the electronic atomizer through the cooperation of the oil tank 100 and the sealing silica gel at the bottom of the oil tank 100. There are a basic oil guiding hole 211 and a supplementary oil guiding hole 212 on the tube wall of the atomizing outer tube 210. The oil liquid enters the oil absorbing cotton 220 through the two oil guiding holes on the tube wall of the atomizing outer tube 210. At this time, the oil absorbing cotton 220 is filled with oil liquid. There is an oil guiding groove 231 on the tube wall of the atomizing inner tube 230. The oil liquid in the oil absorbing cotton 220 enters the oil guiding cotton 240 through the oil guiding groove 231 on the tube wall of the atomizing inner tube 230. At this time, the oil guiding cotton 240 is filled with e-liquid. The outer wall of the atomizing mesh 310 is closely attached to the oil guiding cotton 240, and the oil liquid in the oil guiding cotton 240 is adsorbed on the surface of the atomizing mesh 310.

[0057] During use, an electric current is supplied to the atomizing mesh 310 through a wire. After the atomizing mesh 310 is powered on, it generates heat, causing the oil liquid adsorbed on the surface of the atomizing mesh 310 to be atomized. The atomized oil mist sequentially enters the user's mouth through the inner tube wall of the atomizing inner tube 230 and the inner tube wall of the suction nozzle 140 of the electronic atomizer. The present utility model adopts a double-row oil guiding hole structure on the atomizing outer tube 210. The lower one is the basic oil guiding hole 211, which meets the oil guiding speed required for general low-power atomization. The supplementary oil guiding hole 212 is added above, and the oil guiding speed is increased to meet the oil guiding speed required for high-power atomization.
