Related technologies often incorporate a return air structure connecting the reservoir to the outside atmosphere. However, these return air structures often suffer from obstructed return paths, making it difficult for the atmospheric pressure to balance with the reservoir pressure. This leaves the e-liquid supply problem unresolved, resulting in a poor user experience. Utility Model Content

[0027] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0028] Reference Figures 1 to 5 Firstly, this utility model embodiment proposes an atomizer that optimizes the return air path, making the return air path smoother.

[0029] The atomizer of this embodiment of the utility model is provided with an air passage, an air inlet 510, and an air outlet. The air passage extends between the air inlet 510 and the air outlet. The atomizer includes an oil cup 300, a bracket 100, an oil guide body 200, and a heating element. The oil cup 300 is provided with an oil storage chamber 310, and the bracket 100 is installed inside the oil cup 300. (Refer to...) Figure 1 The support 100 is provided with a receiving cavity 110 and a main return air passage 120. One end of the main return air passage 120 extends to the bottom surface of the support 100 and communicates with the air inlet 510, while the other end extends to the receiving cavity 110, which communicates with the oil storage cavity 310 of the oil cup 300. The oil guide 200 is disposed in the receiving cavity 110 and partially covers the main return air passage 120. One side of the heating element is connected to the oil guide 200, and the air passage flows through the heating element.

[0030] Understandably, the oil guide body 200 can absorb the oil entering the receiving cavity 110, and the heating element heats the oil absorbed by the oil guide body 200 to achieve atomization of the oil. The aerosol generated by atomization flows out through the air passage.

[0031] It should be noted that in some embodiments, the heating element is a heating wire, and the heating element can be separately disposed from the oil guide body 200. Of course, the heating element and the oil guide body 200 can also be an integral structure, and the heating element can also be a heating film or other heating structure, which is not limited here. The heating element and the oil guide body 200 can be planar.

[0032] Understandably, since the main return air channel 120 extends to the bottom surface of the bracket 100 and is directly connected to the external atmosphere, during the normal process of drawing atomized gas, as the oil is consumed, a negative pressure is generated in the oil storage chamber 310. Some of the gas passes through the bottom surface of the bracket 100 and enters the atomizer through the main return air channel 120, ensuring that the negative pressure in the oil storage chamber 310 and the atmospheric pressure tend to be balanced, ensuring smooth oil supply and improving the user's experience.

[0033] The main return gas passage 120 can be a groove with capillary action on the wall of the receiving cavity 110. The main return gas passage 120 covered by the oil guide 200 allows the oil guide 200 to contact the groove of the main return gas passage 120 to absorb the oil entering the main return gas passage 120 and prevent the oil from leaking through the main return gas passage 120.

[0034] In some embodiments, the bracket 100 is further provided with a return air hole 130, which penetrates the wall of the receiving cavity 110. The main return air channel 120 and the oil storage cavity 310 are connected through the return air hole 130, which can further improve the smoothness of the return air path.

[0035] In some embodiments, the diameter of the return air hole 130 is larger than the depth and width of the main return air channel 120, which can further make the return air path smoother. Specifically, in some embodiments, the diameter of the return air hole 130 is designed to be 0.5 mm, the depth of the main return air channel 120 is designed to be 0.2 mm, and the width of the main return air channel 120 is designed to be 0.3 mm.

[0036] In some embodiments, two main return air channels 120 are provided, and the two main return air channels 120 are symmetrically arranged on the bracket 100. This can ensure the return air balance on both sides of the bracket 100, and allow the oil guide body 200 to roughly balance the oil absorption on both sides of the receiving cavity 110. The oil is more evenly absorbed into the heating area of ​​the heating element through the oil guide body 200 for heating and atomization, which can improve the liquid atomization effect.

[0037] In some embodiments, refer to Figure 2 and Figure 4A return air groove 140 is formed between the lower end face of the oil guide body 200 and the lower wall surface of the receiving cavity 110, so that the atmosphere can enter the receiving cavity 110 through the main return air channel 120 and flow along the wall surface of the receiving cavity 110.

[0038] In some embodiments, the width of the return air groove 140 in the vertical direction is greater than or equal to 0.2 mm. A return air groove 140 with a width of not less than 0.2 mm can ensure smooth airflow.

[0039] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 The bracket 100 is also equipped with a secondary air return channel 150, the upper end of which is connected to the air return groove 140, and the secondary air return channel 150 extends downward. During the use of the atomizer, even with the main air return channel 120, there may still be cases of inhaling off-odors or burnt smells. The secondary air return channel 150 can further improve the smoothness of air return and effectively reduce the generation of off-odors or burnt smells.

[0040] In some embodiments, multiple secondary return air channels 150 are provided, and the multiple secondary return air channels 150 are arranged in parallel to each other to form a return air grid. The upper end of each secondary return air channel 150 is connected to the return air groove 140, which can further facilitate the smooth return of air.

[0041] In this embodiment, the depth of the secondary return air channel 150 is set to 0.6 mm and the width is set to 1 mm. According to the siphon effect, liquid can be trapped in the return air grid, which can help solve the problems of atomizer oil leakage and condensate suction to a certain extent, and improve the user experience.

[0042] In some embodiments, the bottom surface of the support 100 is further provided with a grid structure 160, which penetrates the side wall of the secondary return gas channel 150 in the support 100. The grid structure 160 and the secondary return gas channel 150 are separated from each other, and the grid structure 160 is used to further absorb and store condensate.

[0043] In some embodiments, the extending direction of the grid structure 160 is perpendicular to the extending direction of the secondary return gas channel 150, which can reduce the area occupied by the side wall of the support 100 where the secondary return gas channel 150 is provided, and increase the storage space for storing condensate.

[0044] In some embodiments, refer to Figure 3 and Figure 4 The atomizer also includes a base 500, with a bracket 100 connected to the upper end of the base 500. The outer peripheral wall of the base 500 is connected to the inner wall of the oil cup 300. An air inlet 510 is located on the base 500, as shown in the reference diagram. Figure 5The bracket 100 has a side wall shielding portion of the air inlet 510 in the secondary air return channel 150. With this configuration, during inhalation, the gas can flow directly from the air inlet 510 of the atomizer base 500 into the secondary air return channel 150 and into the air return groove 140, effectively achieving the auxiliary air return function.

[0045] In some embodiments, refer to Figure 3 and Figure 4 The atomizer also includes an oil suction body 600. A mounting groove is provided at the upper end of the base 500. The mounting groove is connected to the air inlet 510. The oil suction body 600 is installed in the mounting groove. A first through hole 610 is provided on the oil suction body 600. The first through hole 610 is part of the air passage. The oil suction body 600 can effectively absorb the downstream condensate.

[0046] In some embodiments, refer to Figure 3 and Figure 4 The atomizer also includes a seal 700, which is connected to the upper end of the base 500 and extends to the outer peripheral wall of the base 500 to seal the inner wall of the base 500 and the oil cup 300. The seal 700 is provided with a second through hole 710, which communicates with the air passage. The second through hole 710 is coaxially arranged with the first through hole 610, and the diameter of the second through hole 710 is larger than that of the first through hole 610. The oil suction body 600 can effectively absorb and receive the downstream condensate.

[0047] The seal 700 can be made of materials such as silicone or rubber.

[0048] In some embodiments, the diameter of the first through hole 610 is the same as the diameter of the air inlet 510, allowing direct atmospheric access into the air passage. In some embodiments, the diameter of the air inlet 510 is greater than or equal to 4.2 mm.

[0049] In some embodiments, the atomizer further includes a support member 400, which is connected to the bracket 100 and has an atomization channel. The atomization channel opens towards the receiving cavity 110. (Refer to...) Figure 2 The heating element covers the atomization channel, which is part of the air passage. With the support 400, the oil guide 200 can be installed more tightly in the receiving cavity 110, further preventing oil leakage through the main return air passage 120.

[0050] Secondly, this utility model embodiment also proposes an atomizing device, which includes a power supply component and an atomizer as proposed in any embodiment of the first aspect, wherein the power supply component is electrically connected to the heating element in the atomizer, specifically, the power supply component is used to supply power to the heating element.

[0051] Since the atomizing device uses the aforementioned atomizer, it also possesses all the beneficial effects of the aforementioned atomizer, which will not be elaborated upon here.
