[0028] The serial numbers of components in this document, such as "first", "second", etc., can be used to distinguish the described objects, and do not have any order or technical meaning. Unless otherwise specified, "connected", "coupled" in this application includes direct and indirect connections (couplings).

[0029] In existing atomization device products, in order to supplement the aerosol substrate in the liquid storage cavity, a liquid supplementing device is usually directly connected to the liquid storage cavity to add aerosol substrate into the liquid storage cavity. This way, the flow of aerosol substrate is difficult to control, which leads to the leakage of aerosol substrate.

[0030] Please refer to FIG. 1 to FIG. 6, the embodiment of the present application provides a flow guide assembly 1 for guiding the flow of aerosol substrate in an atomization device, which comprises a casing assembly 11 and a liquid guide 13.

[0031] The casing assembly 11 is provided with a liquid storage cavity 111 and a liquid inlet 113. The liquid storage cavity 111 is used to store aerosol substrate, and the liquid inlet 113 is connected to the liquid supplementing device 3, which is used to guide the aerosol substrate in the liquid supplementing device 3 into the liquid storage cavity 111. The casing assembly 11 itself forms a containing cavity, which is used to contain various components in the flow guide assembly 1, including but not limited to an atomizer 12, a liquid guide 13, etc. The atomizer 12 is used to heat the aerosol substrate to form aerosol, so the atomizer 12 is usually directly arranged in the liquid storage cavity 111 for storing aerosol substrate, so that the atomizer 12 can directly heat the aerosol substrate in the liquid storage cavity 111 to generate aerosol when it works.

[0032] The composition of the atomizer 12 includes an atomization core 121 and a liquid storage medium 122. The liquid storage medium 122 is used to store aerosol substrate, and the atomization core 121 is used to heat the aerosol substrate in the liquid storage medium 122 to generate aerosol, which is finally discharged outward through the gas outlet 112 formed on the casing assembly. For example, the heating element in the atomization core 121 can be a MESH grid heating element or a spiral heating wire, and the liquid storage medium 32 can be cotton, glass fiber, ceramic, etc.

[0033] The casing assembly 11 is provided with structures such as a liquid storage cavity 111, a liquid inlet 113, and a gas outlet 112. In order to form these structures, the casing assembly 11 can be realized by one or more layers of structure, that is, the casing assembly 11 can be integrally formed by one component, or formed by the combination of multiple components. The components can be made of the same or different materials, and connected directly or indirectly through connecting pieces.

[0034] The liquid inlet 113 is connected with the liquid supplement device 3; the aerosol substrate is stored in the liquid supplement device 3, which serves as a supplement of the aerosol substrate in the storage cavity 111, and the aerosol substrate in the liquid supplement device 3 can flow into the storage cavity 111.

[0035] The connection between the liquid inlet 113 and the liquid supplement device 3 can be a sealed connection, so that the aerosol substrate does not leak from the connection between the liquid inlet 113 and the liquid supplement device 3. The sealed connection can be achieved by providing an elastic sealing member including a silica gel ring at the liquid inlet 113.

[0036] The gas outlet 112 is not only used for discharging the aerosol, but also used for communicating with the pneumatic switch through a pneumatic air channel, so that the pneumatic switch can trigger the atomizer 12 to enter the working state by detecting the change of the air pressure, and heat the aerosol substrate to generate the aerosol. The pneumatic air channel and the main air channel can be in communication with each other, and in this case, the pneumatic air channel can serve as a branch of the main air channel; or the pneumatic air channel and the main air channel can be isolated from each other, so as to avoid mutual flow.

[0037] Please refer to FIGS. 2 to 4, in order to reduce the flow of the aerosol substrate between the liquid supplement device 3 and the storage cavity 111, and improve the stability of the liquid supplement flow, the flow guide assembly 1 in the embodiment of the present application includes a liquid guide 13, which includes a first end 131 and a second end 132 arranged opposite along the axial direction, the first end 131 is arranged at the side of the storage cavity 111, and the second end 132 is arranged at the side of the liquid inlet 113, and the second end 132 can be inserted into the liquid supplement device 3 through the liquid inlet 113; the liquid guide 13 is used for conducting the aerosol substrate in the liquid supplement device 3 to the storage cavity 111, and the atomizer 12 is used for heating the aerosol substrate in the storage cavity 111 to generate the aerosol and discharge the aerosol from the gas outlet 112. The first end 131 of the liquid guide 13 means that the liquid guide 13 is detachably fixedly connected with other components in the flow guide assembly 1 through the first end 131, so as to avoid the liquid guide 13 from separating from the flow guide assembly 1; and the second end 132 means the end of the liquid guide 13 which is not involved in the connection, and the second end 132 is not restricted except the body of the liquid guide 13, so the second end 132 can serve as the starting point of the aerosol substrate flowing out of the liquid supplement device 3, and the aerosol substrate can flow from the liquid supplement device 3, through the second end 132 of the liquid guide 13 along the liquid guide 13 into the storage cavity 111. Since the second end 132 of the liquid guide 13 can be inserted into the liquid supplement device 3, the second end 132 reduces the opening area of the liquid supplement device 3, thereby reducing the flow of the aerosol substrate; and the aerosol substrate in the liquid supplement device 3 also flows along the liquid guide 13, thereby improving the stability of the aerosol substrate during the process of conducting the aerosol substrate to the storage cavity 111, and greatly reducing the risk of leakage.

[0038] In an embodiment, the first end 131 and other components in the flow guide assembly 1 are not connected, but the liquid guide 13 is kept in a preset position by the second end 132. For example, the second end 132 and the second free end 142 are fixedly connected.

[0039] The liquid guide 13 is used to guide the aerosol substrate so that the aerosol substrate can flow along the arrangement direction of the liquid guide 13. Based on different flow guiding principles of the liquid guide 13, the aerosol substrate can be guided by surface flow or capillary phenomenon. The surface flow means that the aerosol substrate flows along the outer surface of the liquid guide 13, and the liquid guide 13 serves as a carrier for the flow of the aerosol substrate and provides a flow direction for the aerosol substrate, thereby avoiding unstable flow rate caused by the directionless flow of the aerosol substrate. The capillary phenomenon flow means that the liquid guide 13 uses capillary phenomenon to absorb the aerosol substrate and make the aerosol substrate flow in the liquid guide 13. Specifically, the liquid guide 13 corresponding to the surface flow can be any surface dense component, including but not limited to glass, silica gel and other surface dense materials. The liquid guide 13 corresponding to the capillary phenomenon flow can be a porous material such as ceramic or liquid storage cotton. In some embodiments of the present application, the material of the liquid guide 13 is silica gel to realize surface flow.

[0040] The purpose of the liquid guide 13 is to guide the aerosol substrate and reduce the opening area of the liquid supplement device 3. In order to guide the aerosol substrate into the liquid storage cavity 111, the first end 131 of the liquid guide 13 is arranged close to the liquid storage cavity 111, and the liquid guide 13 is in communication with the liquid storage cavity 111, so that the aerosol substrate on the liquid guide 13 can enter the liquid storage cavity 111 along the communication part with the liquid storage cavity 111.

[0041] In some optional embodiments, referring to FIG. 5 and FIG. 6, in order to facilitate the insertion of the liquid guide 13 into the liquid supplement device 3, the liquid guide assembly 1 in the present application can further include a puncture tube 14, which is sleeved on the liquid guide 13. The puncture tube 14 includes a second fixed end 141 and a second free end 142 arranged in opposite directions along the axial direction. The second fixed end 141 is arranged on the side of the liquid storage cavity 111, and the second free end 142 is arranged on the side of the liquid inlet 113. The second free end 142 is used to be inserted into the liquid supplement device 3 through the liquid inlet 113, so that the second end 132 is inserted into the liquid supplement device 3 through the space inside the wall of the puncture tube 14. Similar to the liquid guide 13, the puncture tube 14 also includes a second fixed end 141 and a second free end 142 arranged in opposite directions along the axial direction. The second fixed end 141 is used to be fixedly connected with other parts of the liquid guide assembly 1, and the second free end 142 can be inserted into the liquid supplement device 3. The liquid guide 13 is inserted into the liquid supplement device 3 to achieve the flow guide. The purpose of arranging the puncture tube 14 is to directly damage the cover of the opening of the liquid supplement device 3 by using the puncture tube 14, without the need to specially remove the cover. At the same time, it can avoid the direct damage of the cover by the liquid guide 13, which can cause the direct and close contact between the liquid guide 13 and the residual cover. By damaging the cover through the puncture tube 14, the outer wall of the puncture tube 14 is in close contact with the cover, and the liquid guide 13 is inserted into the liquid supplement device 3 through the space inside the wall of the puncture tube 14. That is, the function of the liquid guide 13 is not affected, and the liquid guide 13 can normally guide the flow. Moreover, since the puncture tube 14 has damaged the cover, the liquid guide 13 can be more easily inserted into the liquid supplement device 3.

[0042] In some optional embodiments, in order to improve the flow guide effect, a liquid storage gap 130 is formed between the puncture tube 14 and the liquid guide 13. The purpose of arranging the liquid storage gap 130 is that the aerosol substrate flows along the arrangement direction of the liquid guide 13 during the process of guiding the aerosol substrate in the liquid supplement device 3, and the liquid storage gap 130 can serve as the space required for the flow of the aerosol substrate.

[0043] In some optional embodiments, in order to improve the guiding effect, the second fixed end 141 of the puncture tube 14 can be directly fixedly arranged in the liquid storage cavity 111, and the wall of the puncture tube 14 in the liquid storage cavity 111 is provided with at least one liquid guiding hole 143, and the liquid guiding hole 143 communicates the liquid storage gap 130 and the liquid storage cavity 111. Since the liquid guiding hole 143 communicates the liquid storage gap 130 and the liquid storage cavity 111, the aerosol substrate flowing in the liquid storage gap 130 can enter the liquid storage cavity 111 through the liquid guiding hole 143. The liquid guiding hole 143 can be arranged around the wall of the puncture tube 14, so as to avoid the aerosol substrate in the liquid storage cavity 111 from being blocked. The second fixed end 141 of the puncture tube 14 fixedly arranged in the liquid storage cavity 111 can be fixedly connected through a detachable connecting structure, including but not limited to buckle connection, threaded fastening connection and the like.

[0044] In some optional embodiments, in order to fix the puncture tube 14, the liquid guiding member 13 can further include a mounting flange 133 arranged in the circumferential direction, and the liquid guiding member 13 and the puncture tube 14 are interference-connected through the mounting flange 133. The mounting flange 133 can make the size of the liquid guiding member 13 at the corresponding position larger, so as to form an interference fit with the inner wall of the puncture tube 14, so that the puncture tube 14 indirectly realizes the fixed connection with the flow guiding assembly 1 through the liquid guiding member 13.

[0045] In some optional embodiments, in order to improve the guiding effect of the liquid guiding member 13, the length of the second end 132 inserted into the liquid supplementing device 3 is greater than the length of the second free end 142 inserted into the liquid supplementing device 3. This means that the liquid guiding member 13 is deeper into the liquid supplementing device 3 than the puncture tube 14, so that the aerosol substrate in the liquid supplementing device 3 can contact the liquid guiding member 13 earlier, so that the liquid guiding member 13 can better realize the guiding effect.

[0046] In some optional embodiments, in order to fix the liquid guide 13 itself and improve the guiding effect of the liquid guide 13, the first end 131 of the liquid guide 13 can be directly fixed in the liquid storage cavity 111, and the first end 131 of the liquid guide 13 is fixedly connected with the inner wall of the liquid storage cavity 111 away from the liquid inlet 113. The terminal point of the liquid guide 13 for guiding the aerosol substrate is in the liquid storage cavity 111, so the liquid guide 13 can be directly inserted into the liquid storage cavity 111, so that the aerosol substrate flowing along the liquid guide 13 can directly flow into the liquid storage cavity 111; at the same time, the liquid guide 13 can be directly fixed through the inner wall of the liquid storage cavity 111, and the fixing mode includes but is not limited to: the liquid guide 13 is integrally formed with the inner wall of the liquid storage cavity 111; the liquid guide 13 is fixedly connected with the inner wall of the liquid storage cavity 111 through a threaded fastening mode; the liquid guide 13 is fixedly connected with the inner wall of the liquid storage cavity 111 through an interference fit mode; and the liquid guide 13 can also be fixedly connected with the inner wall of the liquid storage cavity 111 through adhesion.

[0047] In some optional embodiments, the cross-sectional area of the liquid guide 13 gradually decreases from the first end 131 to the second end 132. The specific form of the liquid guide 13 can be a variable-diameter cylinder, the outer diameter of which gradually decreases from the first end 131 to the second end 132 of the liquid guide 13, so that the second end 132 can be inserted into the liquid supplementing device 3, and the liquid supplementing device 3 with different opening sizes can be adapted. In some embodiments, the liquid guide 13 can also be used to damage the cover of the liquid supplementing device 3, so the smaller the outer diameter of the second end 132 of the liquid guide 13, the better the damage effect on the cover.

[0048] In some optional embodiments, referring to FIG. 3, the gas outlet 112 and the atomizer 12 can be coaxially arranged along a first axis L1, and the liquid guide 13 and the liquid inlet 113 can also be coaxially arranged along a second axis L2, and the first axis L1 and the second axis L2 are staggered with each other. The atomizer 12 is used to heat the aerosol substrate to generate aerosol, so that the coaxial arrangement of the atomizer 12 and the gas outlet 112 can make the aerosol generated by the atomizer 12 directly discharged from the gas outlet 112.

[0049] The liquid guide 13 and the liquid inlet 113 are also coaxially arranged, which can ensure the guiding effect of the liquid guide 13, and the first axis L1 formed by the gas outlet 112 and the atomizer 12 and the second axis L2 formed by the liquid guide 13 and the liquid inlet 113 are staggered with each other, which means that the first axis L1 and the second axis L2 are not on the same axis, so that the internal space of the flow guide assembly 1 can be optimized, including but not limited to facilitating the design of the bottom air inlet channel of the atomizer 12, and avoiding the phenomenon that the aerosol substrate is too concentrated around the atomizer 12 after being guided.

[0050] The flow guide assembly 1 provided by the embodiment of the present application is provided with the liquid guide 13 between the liquid storage cavity 111 and the liquid inlet 113, and the liquid guide 13 is used to guide the aerosol substrate, so that the aerosol substrate in the liquid supplement device 3 enters the liquid storage cavity 111 along the liquid guide 13, and the stability of the flow of the aerosol substrate can be effectively improved. Moreover, the opening area of the liquid supplement device 3 is reduced due to the presence of the liquid guide 13, so that the flow of the aerosol substrate is effectively reduced, and the leakage of the aerosol substrate is further avoided.

[0051] The embodiment of the present application also provides an atomization device. Please refer to FIG. 7. The atomization device comprises an atomizer 12, a power supply assembly 2, a liquid supplement device 3 and the flow guide assembly 1 in the embodiment of the present application. The atomizer 12 is fixedly arranged in the liquid storage cavity 111. The power supply assembly 2 is fixedly connected with the shell assembly 11 and is used to supply power to the atomizer 12. The liquid supplement device 3 is connected with the liquid inlet 113, and the second end 132 of the liquid guide 13 can be inserted into the liquid supplement device 3 through the liquid inlet 113. The power supply assembly 2 is used to provide power to the atomizer 12, and the atomizer 12 is used to heat the aerosol substrate into aerosol. The atomization device can be a disposable product or a refillable product. For the disposable atomization device, the atomizer 12 and the power supply assembly 2 can be fixedly connected. For the refillable atomization device, the atomizer 12 and the power supply assembly 2 can be detachably connected, and the atomizer 12 and the power supply assembly 2 can be replaced according to the use condition.

[0052] The liquid supplement device 3 is connected with the liquid inlet 113, and the second end 132 of the liquid guide 13 can be inserted into the liquid supplement device 3 through the position of the liquid inlet 113, so that the aerosol substrate in the liquid supplement device 3 can flow out along the liquid guide 13 and be conducted into the liquid storage cavity 111 by the liquid guide 13.

[0053] The above-mentioned atomization device can be an embodiment of the present application, and other atomization devices with corresponding structures in the embodiment of the present application are also within the protection scope of the present application, and the internal specific structure of the atomization device will not be described again.
