Therefore, the second channels 212 can be provided with a plurality of bending structures 212a, so as to prevent the liquid from flowing, thereby realizing the effect of preventing the liquid from leaking.

As shown in fig. 3, in one possible embodiment, the return air channel 2 includes a first return air port 23 and a second return air port 24, and an arc-shaped flow guiding surface 22 is disposed in the return air channel 2, where the flow guiding surface 22 is located in the second channel 212, and the flow guiding surface 22 has a first flow guiding surface 221 and a second flow guiding surface 222, the first flow guiding surface 221 is located on a side close to the first return air port 23, the second flow guiding surface 222 is located on a side close to the second return air port 24, and the first flow guiding surface 221 and the second flow guiding surface 222 are both recessed in a direction close to the second return air port 24.

The air return structure 21 is provided with a flow guiding surface 22, the flow guiding surface 22 is provided with a first flow guiding surface 221 and a second flow guiding surface 222, when the liquid flows in from the first air return opening 23, the liquid flows to the first flow guiding surface 221 after passing through the first channel 211, the first flow guiding surface 221 is arc-shaped and is recessed towards the direction of the second air return opening 24, at this time, the liquid is collected at the recess of the first flow guiding surface 221 and the bending structure 212a, and then flows to the second channels 212 at two sides of the flow guiding surface 22, so that the flow of the liquid in the air return channel 2 is blocked. When the gas flows in from the second air return port 24, the gas flows to the second guide surface 222 after passing through the first channel 211, the second guide surface 222 is also arc-shaped and is concave towards the direction of the second air return port 24, and the gas can smoothly enter the second channel 212 after passing through the second guide surface 222 and flow to the first air return port 23, so that the fluid circulation in the air return channel 2 is more smooth.

As shown in fig. 4, in one possible embodiment, the communication section has a transverse channel 31 and a longitudinal channel 32, the transverse channel 31 being capable of communicating with the longitudinal channel 32;

the connecting channel 3 can have a plurality of transverse channels 31 and a plurality of longitudinal channels 32, the transverse channels 31 and the longitudinal channels 32 being arranged at a distance from one another.

The connecting channel 3 has at least two communicating sections, the communicating section can have a plurality of transverse channels 31 and longitudinal channels 32, and transverse channels 31 can communicate with longitudinal channels 32, and transverse channels 31 and longitudinal channels 32 still have preset contained angles, when liquid flows into the connecting channel 3 from the return air channel 2, liquid passes through a plurality of transverse channels 31 and longitudinal channels 32 in succession, therefore the length of the liquid flowing through the connecting channel 3 is prolonged, thereby also playing a role in blocking liquid, and reducing the possibility of liquid flowing out of the connecting channel.

As shown in fig. 5 to 7, in one possible embodiment, the air return structures 21 can be arranged at continuous intervals along the direction of the first channel 211 and/or symmetrically around the first channel 211 continuously along the direction of the first channel 211.

The air return channel 2 can be provided with a plurality of air return structures 21, and the plurality of air return structures 21 can be continuously arranged or symmetrically arranged with the first channel 211 as a center along the extending direction of the first channel 211 and are mutually communicated.

By such a design, the number of the air return structures 21 can be increased, and the liquid enters the air return channel 2 from the first air return opening 23 and flows towards the second air return opening 24, and at this time, the air return channel 2 has a blocking effect on the liquid, so that the liquid is difficult to flow out of the air return channel 2. The gas enters the gas return channel 2 from the second gas return port 24 and flows towards the first gas return port 23, and the gas return channel 2 enables the gas to flow easily, and flows out from the first gas return port 23, so that the gas return process is completed. The air return structures can be arranged in different modes and in different numbers according to the conditions of liquid circulation and gas circulation, so that the effect of regulating fluid circulation is achieved.

As shown in fig. 8, in a possible embodiment, the air return channel 2 is provided on the main body 1, the air return channel 2 has a plurality of interconnected air return structures 21, the first air return opening 23 is connected to the oil reservoir 5, the second air return opening 24 is connected to the connecting channel 3, and the connecting channel 3 is connected to the outside air, which can enter through the connecting channel 3, and flows from the second air return opening 24 to the first air return opening 23. Liquid can enter from the first air return opening 23, and both the air return channel 2 and the connecting channel 3 have the effect of blocking the liquid flow, wherein the connecting channel 3 further enhances the force capability of blocking the liquid flow and has good liquid leakage prevention effect.

As shown in fig. 9 and 10, in one possible embodiment, the air return structures 21 can be arranged at intervals along the direction of the first channel 211 and can be symmetrically arranged to enhance the liquid blocking effect of the air return structures 21. The specific number of the air return structures 21 can be selected according to actual use conditions, so that the effect of adjusting fluid flow is achieved, the possibility of liquid leakage is reduced, and meanwhile, gas circulation is smoother.

As shown in fig. 11 to 15, in one possible embodiment, the return air channels 2 can be symmetrically arranged on the same plane of the main body 1, so that the first return air openings 23 are located on the same side of the main body 1. The two return air channels 2 can simultaneously carry out the circulation process of fluid, so that the air entering the oil storage bin 5 is increased, and the negative pressure in the oil storage bin 5 is balanced.

As shown in fig. 16, in one possible embodiment, the member a further includes an upper cover 4, the upper cover 4 being provided with mounting holes 41, the upper cover 4 being mounted to the main body portion 1 through the mounting holes 41.

The upper cover 4 may be made of silica gel, and the upper cover 4 is mounted to the main body 1 through the mounting hole 41, and at this time, the upper cover cannot close the first air return opening 23, as shown in fig. 17. As can be seen from the gas pressure curve of the oil storage bin 5 in fig. 21, the pressure in the front oil storage bin 5 is smooth, but the back air return channel 2 is filled with liquid, so that air return is more difficult. Therefore, as the liquid fills the return air passage 2, the gas is also difficult to circulate in the return air passage 2.

As shown in fig. 18, in one possible embodiment, the air return channel 2 includes a first air return opening 23, the upper cover 4 is capable of blocking the first air return opening 23, the first air return opening 23 is located on a side wall of the main body portion 1, and the first air return opening 23 penetrates the top wall of the main body portion 1 upward in the height direction of the member a of the aerosol-forming device;

during ventilation, the upper cover 4 can open the first air return opening 23 through the air effect, so that the air enters the oil storage bin 5, and during non-ventilation, the upper cover 4 can seal the first air return opening 23.

The first air return opening 23 is located on the side wall of the main body part 1 and is arranged upwards in the height direction, namely, the first air return opening 23 is not formed on the side wall of the oil storage bin 5, when the upper cover 4 is installed on the main body part 1, the upper cover 4 can seal the first air return opening 23, the upper cover 4 can open the first air return opening 23 under the action of gas, and the gas in the air return channel 2 enters the oil storage bin 5, so that the pressure in the oil storage bin 5 is regulated. When no gas acts, the upper cover 4 can seal the first air return opening 23, so that the liquid in the oil storage bin 5 cannot leak outwards, the leakage prevention capability is further enhanced, as can be seen from the gas pressure curve of the oil storage bin 5 in fig. 22, the initial negative pressure is larger, probably because in the initial state, the inner surface of the upper cover 4 is tightly attached to the surfaces of the main body part 1 positioned at two sides of the first air return opening 23, the upper cover is difficult to open, once the upper cover is opened once, the liquid enters between the two surfaces to play a lubricating role, the subsequent first air return opening 23 can be smoothly opened, the air return process can be smoothly carried out, the possibility of difficult gas circulation caused by filling the liquid into the air return channel 2 is reduced, and the problem that the first air return opening 23 is inconvenient to open still exists.

As shown in fig. 19, in one possible embodiment, the main body 1 is not provided with the positioning posts 6, and the first return air opening 23 is closed when the upper cover 4 is mounted to the main body 1. The positioning column 6 is removed, so that the upper cover 4 is easier to jack up under the action of gas, meanwhile, the mode of reducing the hardness of silica gel can be adopted, the thickness of a non-sealing surface at the top of the upper cover 4 is thinned, the upper cover 4 can be easier to jack up by gas, and the first return air port 23 is opened, so that the gas smoothly enters the oil storage bin 5. At this time, the first air return opening 23 is not directly communicated with the oil storage bin 5, so that the gas action and the area of the upper cover 4 can be increased, and the first air return opening 23 is easier to open. As can be seen from the gas pressure curve of the oil storage bin 5 in fig. 23, the initial negative pressure is reduced, after the upper cover 4 opens the first air return port 23 for the first time, the first air return port 23 can be smoothly opened by the subsequent gas due to the lubrication action of the liquid, so that the possibility of difficult gas circulation caused by filling the air return channel 2 with the liquid is reduced, and the problem that the first air return port 23 is inconvenient to open is also solved.

As shown in fig. 20, in one possible embodiment, the upper cover 4 has a baffle 42, the baffle 42 being capable of blocking the first return air opening 23, the first return air opening 23 being provided in the top wall of the main body portion 1;

the baffle 42 can open the first return air port 23 by the action of gas during ventilation to allow gas to enter the oil reservoir 5, and the baffle 42 can close the first return air port 23 when not ventilation.

The first air return opening 23 is arranged on the top wall of the main body part 1, namely, the first air return opening 23 is connected with the side wall of the oil storage bin, the baffle plate 42 is positioned on the upper cover 4 and is arranged towards the bottom of the oil storage bin 5, so that the baffle plate 42 can seal the first air return opening 23, and when no gas acts, the baffle plate 42 can prevent liquid in the oil storage bin 5 from leaking. Meanwhile, the baffle plate 42 is easier to open under the action of the gas, so that the gas can enter the oil storage bin 5 from the first gas return port 23, and as can be seen from the gas pressure curve of the oil storage bin 5 in fig. 24, the baffle plate 42 is easier to open the first gas return port 23, and the gas return performance is better, so that the gas circulation process is more stable.
