Under the change of temperature, humidity, air pressure and transportation conditions, the atomization device is prone to oil leakage. In order to solve the problem of oil leakage of the atomization device during long-term storage before activation, the related technology uses an oil core separation structure to separate the atomization core and the oil storage cavity before activation of the atomization device.

[0034] The utility model will be explained in further detail below with the specific embodiments combined with the drawings. In different embodiments, similar elements are marked with similar element numbers. In the following embodiments, many details are described in order to make the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials or methods. In some cases, some operations related to the present application are not shown or described in the specification in order to avoid the core part of the present application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for those skilled in the art, who can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0035] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments.

[0036] In this paper, the serial numbers of components, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connection (coupling).

[0037] In some embodiments, an atomization device is provided, which includes an atomizer and a power supply unit connected with the atomizer. The power supply unit and the atomizer can be detachably connected or difficult to detachably connected. The power supply unit and the atomizer can form an electrical connection, and the power supply unit is used to provide power for the atomizer, and control the opening, closing and output power of the atomizer. The atomizer stores an atomization substrate, which is atomized to generate aerosol after being heated.

[0038] Please refer to Figure 1 and Figure 2In some embodiments, an atomizer is provided, which includes a housing 1, an atomizing core 2, a first sealing rod 3 and a second sealing rod 4. The housing 1 encloses a cavity, and has an air inlet 11 and an air outlet 12 respectively communicating with the cavity. The air inlet 11 and the air outlet 12 respectively communicate the cavity with the atmosphere outside the housing 1. The atomizing core 2 is arranged in the cavity. The cavity has a liquid storage cavity 10 for storing liquid atomizing substrate, and the atomizing core 2 communicates with the liquid storage cavity 10. The atomizing core 2 can form an electrical connection with a power supply unit, and the atomizing core 2 generates aerosol by heating and atomizing the atomizing substrate in an energized state. External air enters the cavity from the air inlet 11, mixes with the aerosol generated by the atomizing core 2, and then flows to the air outlet 12. The mixture of the aerosol and the air flows out of the housing 1 from the air outlet 12, and is inhaled by a user.

[0039] The atomizing core 2 includes a hollow tubular liquid guide 21 and a heating element 22 arranged on the liquid guide 21. The liquid guide 21 has a first end face 211 (see Figure 2 the upper end face of the liquid guide 21) and a second end face 212 (see Figure 2 the lower end face of the liquid guide 21) arranged opposite to each other, and a first central through hole 210 penetrating the first end face 211 and the second end face 212. The first end face 211 is arranged towards the air outlet 12, and the second end face 212 is arranged towards the air inlet 11. The heating element 22 can be combined on the hole wall surface of the first central through hole 210. The liquid guide 21 communicates with the liquid storage cavity 10, and conducts the atomizing substrate in the liquid storage cavity 10 to the heating element 22. The heating element 22 generates aerosol by heating and atomizing the atomizing substrate in an energized state, and the generated aerosol can flow out of the first central through hole 210.

[0040] The atomizer has an activated state and an unactivated state. The unactivated state is the state of the atomizer from the factory to the first time of use by a user. In the unactivated state, the atomizing core 2 and the liquid storage cavity 10 are communicated, and the atomizing core 2 is in a saturated state of adsorbing the atomizing substrate, so that no wick wetting time is needed when the atomizing core 2 is activated.

[0041] Please refer to Figure 2 In the unactivated state, the first sealing rod 3 is located on the side of the liquid guide 21 close to the air outlet 12 (see Figure 2the first sealing rod 3 is inserted into the first central through hole 210. Specifically, the end of the first sealing rod 3 inserted into the first central through hole 210 and the hole wall surface of the first central through hole 210 are in close contact or tight fit, which can effectively reduce the risk of the aerosolization substrate seeping out from the hole wall surface of the first central through hole 210. Even if a small amount of aerosolization substrate seeps out from the gap between the hole wall surface of the first central through hole 210 and the first sealing rod 3, since the first sealing rod 3 blocks the air outlet 12, the phenomenon of the aerosolization substrate leaking outwards will not occur. When it is necessary to activate the atomizer core 2, please refer to Figure 3 The first sealing rod 3 is pulled out from the cavity in the direction close to the air outlet 12, so that the first sealing rod 3 is separated from the first central through hole 210. After the first sealing rod 3 is pulled out, the air outlet 12 and the first central through hole 210 are connected, and the aerosol released from the first central through hole 210 can flow out of the shell 1 through the air outlet 12 for the user to inhale.

[0042] Please refer to Figure 2 In the unactivated state, the second sealing rod 4 is located on the side of the liquid guide 21 close to the air inlet 11 (refer to Figure 2 the lower side of the liquid guide 21). The second sealing rod 4 includes a first part 41 and a second part 42. Moreover, the second sealing rod 4 has a first state and a second state. The first state of the second sealing rod 4 corresponds to the unactivated state of the atomizer, which prevents the aerosolization substrate stored in the atomizer core 2 from leaking outwards; the second state of the second sealing rod 4 corresponds to the activated state of the atomizer. Specifically, please refer to Figure 2 In the first state of the second sealing rod 4, the first part 41 is located in the cavity and abuts against the second end surface 212 of the liquid guide 21, and the second part 42 is connected with the first part 41 and blocks the air inlet 11. Thus, the leakage of the aerosolization substrate from the second end surface 212 of the liquid guide 21 under the action of gravity can be effectively reduced. Even if a small amount of aerosolization substrate seeps out from the gap between the second end surface 212 and the first part 41 of the second sealing rod 4, since the second part 42 of the second sealing rod 4 blocks the air inlet 11, the phenomenon of the aerosolization substrate leaking outwards will not occur. When it is necessary to activate the atomizer core 2, please refer to Figure 3 and Figure 4 The second sealing rod 4 is pulled out in the direction close to the air inlet 11, as Figure 4The second sealing rod 4 is shown to reach a second state, in which the first portion 41 is still located in the cavity and is configured to form a part of the air inlet channel. The second portion 42 is separated from the first portion 41 and is withdrawn from the air inlet 11. After the second portion 42 of the second sealing rod 4 is withdrawn, the air inlet 11 is communicated with the first central through hole 210, and external air can enter the cavity from the air inlet 11 and flow to the first central through hole 210 and mix with the aerosol released at the first central through hole 210.

[0043] In summary, since one end of the first sealing rod 3 blocks the air outlet 12 and the other end of the first sealing rod 3 is embedded in the first central through hole 210 of the liquid guide 21 of the atomizing core 2, the risk of the atomized substrate seeping from the hole wall surface of the first central through hole 210 can be effectively reduced, and even if a small amount of atomized substrate seeps from the gap between the hole wall surface of the first central through hole 210 and the first sealing rod 3, the atomized substrate will not leak outward. In the first state of the second sealing rod 4, since the first portion 41 of the second sealing rod 4 abuts against the second end surface 212 of the liquid guide 21, the atomized substrate can be effectively prevented from leaking out from the second end surface 212 under the action of gravity, and even if a small amount of atomized substrate seeps from the gap between the second end surface 212 and the first portion 41 of the second sealing rod 4, since the second portion 42 of the second sealing rod 4 blocks the air inlet 11, the atomized substrate will not leak outward. In the second state of the second sealing rod 4, the first portion 41 is still located in the cavity and can form a part of the air inlet channel.

[0044] As described above, since the first central through hole 210 and the second end surface 212 of the liquid guide 21 are respectively blocked by the first sealing rod 3 and the second sealing rod 4, the liquid guide 21 has good sealing performance. In the inactivated state of the atomizer, the atomizing core 2 and the liquid storage cavity 10 can be communicated, and the atomizing core 2 can be in a saturated state of absorbing the atomized substrate. Therefore, when the atomizing core 2 is activated for the first time, no priming time is required, and the first few puffs will not have weak aroma or peculiar smell.

[0045] In addition, since the first sealing rod 3 and the second sealing rod 4 are respectively located on opposite sides of the liquid guide 21 of the atomizing core 2 (i.e., one side of the liquid guide 21 close to the air outlet 12 and the other side of the liquid guide 21 close to the air inlet 11), when the atomizing core 2 needs to be activated, the user only needs to withdraw the first sealing rod 3 and the second sealing rod 4 from the air outlet 12 and the air inlet 11, respectively. The length of each sealing rod will not be too long, and the withdrawal path of each sealing rod will not be too long, so that the sealing rod can be withdrawn more conveniently and labor-savingly.

[0046] As described above, Figure 3As shown, before the second sealing rod 4 transitions from the first state to the second state, there is an intermediate state in which the second sealing rod 4 moves down a certain distance relative to the first state, causing the first part 41 and the second end face 212 to separate from each other to form an air intake gap 5. The second part 42 is still connected to the first part 41, and the second part 42 has not yet separated from the first part 41.

[0047] like Figure 4 and Figure 5 As shown, in some embodiments, in the second state, the first portion 41 and the second end face 212 are separated to form an air intake gap 5, and the air intake 11, the air intake gap 5, and the first central through hole 210 are sequentially connected. Please refer to the airflow path diagram. Figure 5 The dotted line with arrows in the middle. Thus, outside air can flow sequentially through the air inlet 11, the air inlet interval 5 and the first central through hole 210, carrying the aerosol generated by the atomizing core 2 to the air outlet 12.

[0048] like Figures 5 to 7 As shown, in some embodiments, the housing 1 is provided with a boss 6, which is located inside the cavity, disposed around the air inlet 11, and located on the side of the first portion 41 of the second sealing rod 4 away from the liquid guide 21 (i.e., Figure 5 (The lower side of the first part 41). The boss 6 has a third end face 63 facing the first part 41, and an outer side face 65 and an inner side face 64 connected to the third end face 63. The boss 6 is provided with a first through hole 61 and a second through hole 62. The second through hole 62 extends from the third end face 63 to the air inlet 11, and the first through hole 61 extends through the outer side face 65 and the inner side face 64. The first through hole 61 communicates with the second through hole 62 radially. Specifically, as Figure 7 In the illustrated embodiment, the first through hole 61 can be a groove formed by recessing downward from the third end face 63, that is, the first through hole 61 can simultaneously penetrate the outer side face 65, the inner side face 64, and the third end face 63. Alternatively, in some other embodiments, the first through hole 61 can only penetrate the outer side face 65 and the inner side face 64, without penetrating the third end face 63, and the first through hole 61 is a hole formed on the side wall of the boss 6.

[0049] like Figure 2 As shown, in the first state of the second sealing rod 4, the first part 41 and the boss 6 are not in contact, and the second part 42 passes through the second through hole 62 to block the air inlet 11. A portion of the second part 42 may protrude beyond the air inlet 11, making it convenient for the user to remove the end of the second part 42 away from the first part 41. Figure 5As shown, in the second state of the second sealing rod 4, the first part 41 abuts against the boss 6, the first part 41 abuts against the third end face 63 and is partially embedded in the second through hole 62. The portion of the first part 41 embedded in the second through hole 62 serves to block the second through hole 62, and the first part 41 is thus fixed to the boss 6, so that the first part 41 is fixed directly below the liquid guide 21 of the atomizing core 2. Alternatively, in some other embodiments, the first part 41 may not contact the third end face 63, but may be completely embedded in the second through hole 62 for fixation. The air inlet 11, the first through hole 61, the air inlet interval 5 and the first central through hole 210 are sequentially connected. Please refer to the airflow path. Figure 5 The dotted line with arrows in the middle. Thus, outside air can flow sequentially through the air inlet 11, the first through hole 61, the air inlet interval 5 and the first central through hole 210, carrying the aerosol generated by the atomizing core 2 to the air outlet 12.

[0050] from Figure 5 It can be seen that in the second state of the second sealing rod 4, that is, the activated state of the atomizer, after the first part 41 separates from the second end face 212 of the liquid guide 21, the second end face 212 of the liquid guide 21 is exposed to the cavity, and the un-atomized, residual atomized matrix in the liquid guide 21 will drip downwards under the action of gravity. Since the first part 41 is fixed directly below the liquid guide 21 of the atomizing core 2, the first part 41 faces the surface of the liquid guide 21 (that is... Figure 5 The upper surface of the first part 41 can be used to collect the atomized matrix dripping from the second end face 212 of the liquid guide 21. When a large amount of atomized matrix drips onto the first part 41, it is guided to the periphery of the boss 6. In this way, the first part 41 and the boss 6 respectively become obstacles to the flow of the atomized matrix dripping from the second end face 212 of the liquid guide 21 to the air inlet 11, thereby effectively reducing the risk of the atomized matrix dripping from the second end face 212 of the liquid guide 21 leaking out from the air inlet 11, and the sealing performance is good.

[0051] Please refer to the following: Figure 2 , Figure 5 , Figure 8 and Figure 9 In some embodiments, the outer casing 1 includes a main body 13 and a bottom cover 14. The atomizer also includes a support 15. The main body 13 and the bottom cover 14 are connected and together enclose a cavity. The air inlet 11 and the boss 6 are both formed on the bottom cover 14, and the support 15 is disposed within the cavity. The support 15 has a second central through hole 150. Figure 2 As shown, the fluid guide 21 is fitted and fixed in a portion of the second central through hole 150. In the first state of the second sealing rod 4, the first portion 41 is fitted and fixed in another portion of the second central through hole 150. Figure 5As shown, in the second state, the first part 41 is removed from the second central through hole 150. Thus, the bracket 15 acts as a circumferential limiter for the liquid guide 21 and the first part 41 of the second sealing rod 4, so that the first part 41 can be held in the position abutting against the second end face 212 of the liquid guide 21 in the first state.

[0052] Furthermore, in some embodiments, the first portion 41 and the second central through hole 150 of the second sealing rod 4 can be an interference fit, thereby minimizing leakage of the atomized matrix from the gap between the hole walls of the first portion 41 and the second central through hole 150, resulting in better sealing.

[0053] like Figure 2 As shown, in some embodiments, the inner wall surfaces of the support 15 and the shell body 13 together form a liquid storage cavity 10. The support 15 is provided with a liquid guiding channel 151 communicating with the second central through hole 150, which connects the liquid storage cavity 10 and the liquid guiding 21. Specifically, the end face of the support 15 facing away from the bottom cover 14 (i.e.,...) Figure 2 The upper end face of the middle support 15 has a circumferentially recessed liquid guiding groove, which is inclined to guide the liquid 21, forming a liquid guiding channel 151. Alternatively, in some other embodiments, the liquid guiding channel 151 can also have other structural forms. For example, the liquid guiding channel 151 can extend downward from the end face of the support 15 away from the bottom cover 14 and then bend inward to guide the liquid 21. Thus, the support 15 can also serve to connect the liquid storage chamber 10 and the liquid guiding 21.

[0054] like Figure 2 As shown, in some embodiments, the outer casing 1 further includes a suction nozzle inner tube 16. The casing body 13 and the bottom cover 14 are connected and together enclose a cavity. An air inlet 11 is formed on the bottom cover 14. The suction nozzle inner tube 16 is connected to the casing body 13. The end of the suction nozzle inner tube 16 away from the casing body 13 extends into the cavity. The suction nozzle inner tube 16 is located directly above the liquid guide 21. The support 15, the inner wall surface of the casing body 13, and the outer wall surface of the suction nozzle inner tube 16 facing the casing body 13 together enclose a liquid storage cavity 10. The inner wall surface of the suction nozzle inner tube 16 encloses an air outlet channel 160, which is connected to the first central through hole 210. An air outlet 12 is formed at the end of the air outlet channel 160 away from the liquid guide 21. A first sealing rod 3 passes through the air outlet channel 160. During factory assembly, the first sealing rod 3 is inserted into the mouthpiece inner tube 16 through the air inlet 11 to seal the first central through hole 210. When the atomizer needs to be activated, the user simply pulls the first sealing rod 3 upwards.

[0055] Further, in some embodiments, the first sealing rod 3 and the air outlet passage 160 can be in interference fit, so as to avoid the leakage of the atomized substrate from the gap between the first sealing rod 3 and the inner wall surface of the air outlet passage 160 to the greatest extent, and the sealing performance is better.

[0056] As shown in Figure 2 and Figure 10 , in some embodiments, the end of the mouthpiece inner tube 16 away from the shell body 13 is formed with a groove 161, and the cross-sectional dimension of the groove 161 is greater than that of the air outlet passage 160. It should be noted that the transverse direction referred to herein is the C-C direction indicated by the arrow in Figure 2 and Figure 10 . The end of the liquid guide 21 away from the second sealing rod 4 (i.e., the end of the liquid guide 21 close to the air outlet 12, referring to the upper end of the liquid guide 21 in Figure 10 ) is fitted and fixed in the groove 161, and the first end surface 211 of the liquid guide 21 abuts against the groove wall surface of the groove 161. Thus, the first end surface 211 of the liquid guide 21 is extruded by the groove wall surface of the groove 161, which can effectively reduce the leakage of the atomized substrate from the first end surface 211 of the liquid guide 21, whether the atomizer is in the activated state or the inactivated state. Even if a small amount of atomized substrate leaks from the gap between the first end surface 211 and the groove wall surface of the groove 161, since the first sealing rod 3 and the air outlet passage 160 are in interference fit, and the first sealing rod 3 blocks the air inlet 11, the atomized substrate will not leak outward, and the sealing performance is better.

[0057] As shown in Figure 5 , Figure 8 and Figure 9 , in some embodiments, the liquid guide 21 is made of a fiber material, which is soft and easy to deform. The atomizer core 2 further comprises an atomizing tube 23, which is sleeved on the outer periphery of the liquid guide 21 to support the liquid guide 21 and avoid the deformation of the liquid guide 21 caused by extrusion, so that the atomized substrate is not extruded out of the liquid guide 21. The atomizing tube 23 is provided with a liquid inlet hole 230, and part of the liquid guide 21 is exposed to the liquid guide passage 151 through the liquid inlet hole 230. The liquid guide passage 151 on the bracket 15 and the liquid inlet hole 230 are communicated, so that the atomized substrate in the liquid storage cavity 10 can seep into the liquid guide 21 through the liquid guide passage 151 and the liquid inlet hole 230, and finally contact the heating body 22.

[0058] As shown in Figures 2 to 4As shown, in some embodiments, the first sealing rod 3 includes a rod body 31 and a plurality of sealing portions 32. The rod body 31 passes through the air outlet channel 160, and one end of the rod body 31 is embedded in the first central through hole 210. The sealing portions 32 are circumferentially surrounding the outer peripheral surface of the rod body 31. That is, the sealing portion 32 is an annular protrusion protruding relative to the rod body 31, and can be made of an elastic material. The sealing portions 32 and the air outlet channel 160 are interference-fitted, and the cross-sectional dimension of the rod body 31 is smaller than the cross-sectional dimension of the air outlet channel 160. That is, the first sealing rod 3 seals the air outlet channel 160 through the sealing part 32 that surrounds the outer circumferential surface of the rod body 31. There is a gap between the rod body 31 and the air outlet channel 160. This minimizes the direct contact area between the first sealing rod 3 and the air outlet channel 160. As a result, the friction between the first sealing rod 3 and the inner wall of the air outlet channel 160 can be minimized during the process of the first sealing rod 3 being installed into or removed from the air outlet channel 160, making the assembly and removal of the first sealing rod 3 smoother and less strenuous.

[0059] In some embodiments, the first sealing rod 3 includes at least two sealing portions 32, wherein at least one sealing portion 32 is a first sealing portion and at least one sealing portion 32 is a second sealing portion, and the cross-sectional dimension (e.g., the diameter) of the second sealing portion is smaller than the cross-sectional dimension (e.g., the diameter) of the first sealing portion. The first sealing portion is located between the second sealing portion and one end of the rod body 31 inserted into the first central through hole 210. Thus, the second sealing portion is assembled into the air outlet channel 160 before the first sealing portion. At the same time, by setting the diameter of the second sealing portion to be smaller than the diameter of the first sealing portion, it is beneficial for the rod body 31 and the second sealing portion with a smaller interference fit to be smoothly assembled into the air outlet channel 160 first, and then the first sealing portion with a larger interference fit to completely block the air outlet channel 160, effectively improving the assembly smoothness of the first sealing rod 3 and the sealing performance of the first sealing rod 3 for the air outlet channel 160.

[0060] like Figures 2 to 4 As shown, in some embodiments, the first sealing rod 3 further includes a blocking portion 33. This blocking portion 33 is connected to the end of the rod body 31 away from the liquid-conducting 21. The blocking portion 33 is at least partially located outside the air outlet channel 160 and covers the air outlet 12. Specifically, the cross-sectional dimension of the blocking portion 33 is larger than the cross-sectional dimension of the air outlet 12 to cover it. Further, the blocking portion 33 can be fitted to the surface of the shell body of the outer casing 1 around the air outlet 12. These arrangements all contribute to the sealing performance of the first sealing rod 3 at the air outlet 12, preventing the atomized matrix from leaking from the air outlet 12 to the outside.

[0061] like Figure 11As shown, the second sealing rod 4 also includes a connecting portion 43, which connects the first portion 41 and the second portion 42. The cross-sectional dimension of the connecting portion 43 is much smaller than the cross-sectional dimensions of the first portion 41 and the second portion 42. For example, the cross-sectional dimension of the connecting portion 43 can be less than half the minimum cross-sectional dimension of the first portion 41; the cross-sectional dimension of the connecting portion 43 can be less than half the minimum cross-sectional dimension of the second portion 42. The transverse direction referred to by the cross-section can be referenced... Figure 11 The middle arrow indicates the CC direction. This CC is perpendicular to the extraction direction of the second sealing rod 4. By setting the dimensional difference between the connecting part 43 and the first part 41 and the second part 42, the first part 41 and the second part 42 are made easy to break. Figure 3 As shown, when the second sealing rod 4 moves down to the middle state, the first part 41 abuts against the boss 6. At this time, if the second sealing rod 4 is pulled further, as shown... Figure 4 As shown, the first part 41 is restricted by the boss 6 and will not move further down, while the second sealing rod 4 breaks off from the connecting part 43, and the second part 42 separates from the first part 41 and exits the air inlet 11.
