[0002] Electronic cigarettes and electronic devices used to atomize health-care drugs, therapeutic drugs and other substances can be collectively referred to as electronic atomization devices. Currently, the vast majority of electronic atomization devices on the market generally include an atomizer for generating aerosols and a battery assembly for powering the atomizer. As the core component of the electronic atomization device, the atomizer has always been the research focus of technicians in this field.

[0003] In the related art, there are some atomizer structures, including a liquid storage cup, an air flow channel and an atomizer core arranged in the air flow channel, wherein the air flow channel is arranged outside the liquid storage cup and remains connected to the outside world, the liquid storage cup is pre-filled with atomizer liquid (such as e-liquid), and the atomizer core remains connected to the liquid storage cup.

[0004] However, the atomizer of this structure generally has the following problems:

[0005] Since the liquid storage cup is always connected to the atomizer core, when the atomizer is not in use (for example, when the atomizer is in transportation or non-suction state), the atomized liquid in the liquid storage cup may leak from the atomizer core into the air flow channel, and then leak from the air flow channel to the outside.

In particular, when the atomizer is in a non-use state such as high-altitude transportation, low temperature, and low pressure, since the liquid storage cup is in a closed state isolated from the outside world, the inside of the liquid storage cup always maintains a constant pressure state, that is, the air pressure in the liquid storage cup will not change due to the influence of the external environment in which the atomizer is located, thereby preventing the atomizer from leaking. When the atomizer is in use, the atomizer core remains connected to the outside world through the air flow channel, thereby ensuring the normal use and normal operation of the atomizer.

[0038] In addition, since the atomizer core is arranged at the bottom of the liquid storage cup, the atomizer core can be directly electrically connected to the electrode arranged at the bottom of the atomizer, eliminating the need to lead out connecting wires from the atomizer core and then connect the connecting wires to the electrodes at the bottom of the atomizer. This not only facilitates the electrical connection between the atomizer core and the electrodes at the bottom of the atomizer, but also simplifies the structure of the atomizer core, thereby reducing the manufacturing cost of the atomizer core.

[0070] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more features.

[0071] In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel options. Taking "A and / or B" as an example, it includes option A, or option B, or options in which A and B are satisfied at the same time.

[0072] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0073] The utility model provides an atomizer and an electronic atomization device, which can effectively prevent the risk of leakage of atomized liquid by isolating or connecting an atomization core with the outside world so that the atomizer can be switched between a standby state and an in-use state.

[0074] Please refer to Figures 1 to 3 、 Figure 6 、 Figures 10 to 17 、 Figure 19As shown, an embodiment of the present invention provides an atomizer, which includes an outer shell 100 and an atomizer core 200. A liquid storage cup 110 and an air flow channel 120 are provided within the outer shell 100. The air flow channel 120 is provided outside the liquid storage cup 110. The atomizer core 200 is provided at the bottom of the liquid storage cup 110 and is in communication with the liquid storage cup 110. When the atomizer is in a standby state, the atomizer core 200 is isolated from the outside world. When the atomizer is in use, the atomizer core 200 remains in communication with the outside world through the air flow channel 120.

[0075] In this embodiment, the liquid storage cup 110 is used to store the atomized liquid.

[0076] It should be noted that, when implementing the Figure 3 、 6 , 10, 11, 14, 15, 17 and 19, the bottom wall of the liquid storage cup 110 is provided with at least one liquid outlet 113, and the atomizing core 200 provided at the bottom of the liquid storage cup 110 is connected to the liquid storage cup 110 through each liquid outlet 113. In specific implementation, the number of liquid outlet holes 113 can be flexibly set according to actual needs, and can be one or more. This embodiment does not impose specific restrictions on this. In this embodiment, by providing at least one liquid outlet 113 on the bottom wall of the liquid storage cup 110, the atomized liquid in the liquid storage cup 110 can be completely flowed into the atomizing core 200 through each liquid outlet 113 for heating and atomization, which is beneficial to improve the utilization rate of the atomized liquid.

[0077] In the embodiment of the present invention, based on the above-mentioned structural design, when the atomizer is in the standby state, the atomizer core 200 is isolated from the outside world. At the same time, the liquid storage cup 110 connected to the atomizer core 200 is also isolated from the outside world. Therefore, the liquid storage cup 110 and the atomizer core 200 are both in a closed state isolated from the outside world, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 when the atomizer is not in use. In particular, when the atomizer is in a non-use state such as high-altitude transportation, low temperature, and low pressure, since the liquid storage cup 110 is in a closed state isolated from the outside world, the inside of the liquid storage cup 110 always maintains a constant pressure state, that is, the air pressure in the liquid storage cup 110 will not change due to the influence of the external environment of the atomizer, thereby preventing the atomizer from leaking. When the atomizer is in use, the atomizer core 200 remains connected to the outside world through the air flow channel 120, thereby ensuring the normal use and normal operation of the atomizer. The occasions when the nebulizer is not in use include during the transportation of the nebulizer or during the process of not pumping the nebulizer, which are not specifically limited here.

[0078] In addition, since the atomizer core 200 is arranged at the bottom of the liquid storage cup 110, the atomizer core 200 can be directly electrically connected to the electrode arranged at the bottom of the atomizer, eliminating the need to lead out connecting wires from the atomizer core 200 and then connect the connecting wires to the electrodes at the bottom of the atomizer. This not only facilitates the electrical connection between the atomizer core 200 and the electrodes at the bottom of the atomizer, but also simplifies the structure of the atomizer core 200, thereby reducing the manufacturing cost of the atomizer core 200.

[0079] Further, refer to Figure 3 、 Figure 6 、 Figure 10 、 Figure 11 、 Figure 14 、 Figure 15 、 Figure 17 and Figure 19 As shown, the air flow channel 120 has a first air flow port 121 and a second air flow port 122, and the atomizer core 200 is fixedly disposed in the air flow channel 120.

[0080] like Figure 3 、 Figure 14 and Figure 17 As shown, when the atomizer is in a standby state, the first air flow port 121 and the second air flow port 122 of the air flow channel 120 are closed to isolate the atomizer core 200 from the outside world. Specifically, when the first air flow port 121 and the second air flow port 122 are closed, the air flow channel 120 is isolated from the outside world due to the closure of the first air flow port 121 and the second air flow port 122 thereon. In this way, the atomizer core 200 disposed in the air flow channel 120 is also isolated from the outside world. At the same time, the liquid storage cup 110 is also isolated from the outside world and is in a closed state, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 when the atomizer is not in use.

[0081] like Figure 6 、 Figure 10 、 Figure 11 、 Figure 15 and Figure 19As shown, when the atomizer is in use, the first air flow port 121 and the second air flow port 122 are opened so that the atomizer core 200 is connected to the outside world through the air flow channel 120. Specifically, when the first air flow port 121 and the second air flow port 122 are opened, the air flow channel 120 is connected to the outside world through the first air flow port 121 and the second air flow port 122 thereon. In this way, the atomizer core 200 disposed in the air flow channel 120 is also connected to the outside world. Since the atomizer core 200 is connected to the liquid storage cup 110, when the atomizer core 200 is connected to the outside world, the liquid storage cup 110 is also connected to the outside world, thereby ensuring the normal use and normal operation of the atomizer. Specifically, when the user draws on the atomizer, the air pressure in the air flow channel 120 decreases, while the pressure in the liquid storage cup 110 remains constant, so that the air pressure in the air flow channel 120 is lower than the air pressure in the liquid storage cup 110, thereby forming a negative pressure. Therefore, the atomized liquid in the liquid storage cup 110 flows into the atomizer core 200 under the action of the negative pressure, so that the atomizer core 200 is heated and atomized, and the atomizer can then start to be used and operate normally.

[0082] In the embodiment of the present application, the shape of the air flow channel 120 can be L-shaped, and the following two embodiments are provided:

[0083] In one embodiment, the first air flow port 121 of the air flow channel 120 may be an air inlet port provided on one side of the liquid storage cup 110, and the second air flow port 122 of the air flow channel 120 may be an air outlet port provided on the upper side of the liquid storage cup 110. It should be noted that the air inlet port may be provided on the left side or the right side of the liquid storage cup 110, and the specific position is not limited here.

[0084] In another embodiment, referring to Figure 3 、 Figure 6 、 Figure 10 、 Figure 11 、 Figure 14 、 Figure 15 、 Figure 17 and Figure 19As shown, the air flow channel 120 includes an air inlet channel 123 provided at the bottom of the liquid storage cup 110. The air inlet channel 123 has a first air inlet port 1231 and a first air outlet port 1232. The first air flow port 121 of the air flow channel 120 is the first air inlet port 1231 of the air inlet channel 123, and the second air flow port 122 of the air flow channel 120 is the first air outlet port 1232 of the air inlet channel 123. The atomizer core 200 is located between the first air inlet port 1231 and the first air outlet port 1232 of the air inlet channel 123, that is, the atomizer core 200 is located in the air inlet channel 123. In this embodiment, the atomizer further includes an adjusting member 300, which is used to simultaneously close the first air inlet port 1231 and the first air outlet port 1232 of the air inlet channel 123 (as shown in FIG. 1 ). Figures 3 to 5 、 Figure 14 and Figure 17 ), so that the air inlet channel 123 will be isolated from the outside world due to the simultaneous closure of the first air inlet port 1231 and the first air outlet port 1232. In this way, the atomizer core 200 arranged in the air inlet channel 123 will also be isolated from the outside world, that is, the liquid storage cup 110 will also be isolated from the outside world and be in a closed state, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 when the atomizer is not in use. The regulating member 300 is also used to simultaneously open the first air inlet port 1231 and the first air outlet port 1232 of the air inlet channel 123 (such as Figures 6 to 8 、 Figure 10 、 Figure 11 、 Figure 15 and Figure 19 ), so that the air inlet channel 123 remains in communication with the outside world. In this way, the atomizer core 200 disposed in the air inlet channel 123 also remains in communication with the outside world. Since the atomizer core 200 remains in communication with the liquid storage cup 110, when the atomizer core 200 remains in communication with the outside world, the liquid storage cup 110 also remains in communication with the outside world, thereby ensuring the normal use and normal operation of the atomizer.

[0085] In this embodiment, since the air inlet channel 123 is arranged at the bottom outside the liquid storage cup 110, and the air inlet channel 123 has a first air inlet port 1231 and a first air outlet port 1232, when the atomizer is in a standby state, it is only necessary to simultaneously close the first air inlet port 1231 and the first air outlet port 1232 of the air inlet channel 123 through the adjustment member 300. The whole process is very simple and easy to implement.

[0086] In addition, the shape of the air flow channel 120 can also be U-shaped. For example, the first air flow port 121 of the air flow channel 120 can be an air inlet port provided at the upper end of the liquid storage cup 110, and the second air flow port 122 of the air flow channel 120 can be an air outlet port provided at the upper end of the liquid storage cup 110, and the first air flow port 121 and the second air flow port 122 are located on two opposite sides of the upper end of the liquid storage cup 110.

[0087] Furthermore, when the air flow channel 120 includes an air inlet channel 123 disposed at the bottom of the liquid storage cup 110, the air flow channel 120 also includes an air outlet channel 124 disposed outside the liquid storage cup 110, and the air outlet channel 124 has a second air inlet port 1241 and a second air outlet port 1242. Based on this, the regulating member 300 of the present invention provides two structural designs.

[0088] The first structural design of the adjusting member 300 is combined with Figures 1 to 11 As shown, in some structural designs, the second outlet port 1242 of the outlet channel 124 is kept in communication with the outside, and the adjusting member 300 is annular and relatively rotatably mounted on one end of the outer shell 100 close to the inlet channel 120. In this embodiment, as shown in FIG. Figure 2 As shown, the end of the outer shell 100 close to the air inlet channel 120 is the lower end of the outer shell 100, that is, the adjusting member 300 is relatively rotatably mounted on the lower end of the outer shell 100. A first air inlet hole 310 that is in communication with the outside is opened on the side wall of the adjusting member 300, and an air passage 320 is provided on the adjusting member 300 that is spaced apart from the first air inlet hole 310. The air passage 320 has a third air inlet port 321 and a third air outlet port 322. The third air inlet port 321 is arranged corresponding to the first air inlet hole 310. The adjusting member 300 has an upper end surface 330 (as shown in FIG. Figure 2 、 Figure 5 、 Figure 8 and Figure 9 ), the third air outlet port 322 is located on the upper end surface 330 of the regulating member 300, and the second air inlet port 1241 of the air outlet channel 124 is disposed near the upper end surface 330 of the regulating member 300, wherein:

[0089] Combine Figures 3 to 5As shown, when the adjustment member 300 is rotated to the first position relative to the outer shell 100, the first air inlet 310 and the first air inlet port 1231 of the air inlet channel 123 are staggered and isolated from each other. At the same time, the first air outlet port 1232 of the air inlet channel 123 and the third air inlet port 321 of the air passage 320 are staggered and isolated from each other, and the third air outlet port 322 of the air passage 320 and the second air inlet port 1241 of the air outlet channel 124 are staggered and isolated from each other, so that the air inlet channel 123 is isolated from the outside world and the atomizer is in a ready-to-use state. In this way, the atomizer core 200 located in the air inlet channel 123 is also isolated from the outside world, that is, the liquid storage cup 110 is also isolated from the outside world and is in a closed state, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 when the atomizer is not in use.

[0090] Combine Figures 6 to 11 As shown, when the adjusting member 300 is rotated to the second position relative to the outer shell 100, the first air inlet hole 310 is connected to the first air inlet port 1231 of the air inlet channel 123, the first air outlet port 1232 of the air inlet channel 123 is connected to the third air inlet port 321 of the air passage 320, and the third air outlet port 322 of the air passage 320 is connected to the second air inlet port 1241 of the air outlet channel 124, so that the first air inlet hole 310, the air inlet channel 123, the air passage 320 and the air outlet channel 124 are connected in sequence, and the atomizer is in use.

[0091] It should be noted that, combined with Figures 3 to 5 As shown, the above-mentioned "first position" refers to the position where the regulating member 300 rotates to the position where the first air inlet hole 310 thereon is isolated from the first air inlet port 1231 of the air inlet channel 123 and the air passage 320 on the regulating member 300 is isolated from the first air outlet port 1232 of the air inlet channel 123 and the second air inlet port 1241 of the air outlet channel 124. Figures 6 to 11 As shown, the above-mentioned "second position" refers to the position where the adjusting member 300 is rotated to the position where the first air inlet hole 310 thereon is connected to the first air inlet port 1231 of the air inlet channel 123 and the air passage 320 on the adjusting member 300 is simultaneously connected to the first air outlet port 1232 of the air inlet channel 123 and the second air inlet port 1241 of the air outlet channel 124.

[0092] Furthermore, in specific implementation, Figure 2 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9As shown, a boss portion 340 is protruded on the inner wall of the adjusting member 300, and the boss portion 340 has an inner wall surface 341 and a top end surface 342. The top end surface 342 of the boss portion 340 is the upper end surface 330 of the adjusting member 300 mentioned above. The inner wall surface 341 is arranged corresponding to the first air outlet port 1232 of the air inlet channel 123, and the top end surface 342 is arranged corresponding to the second air inlet port 1241 of the air outlet channel 124. The third air inlet port 321 of the air passage 320 is located on the inner wall surface 341, and the third air outlet port 322 of the air passage 320 is located on the top end surface 342, that is, the air passage 320 is arranged from the inner wall surface 341 of the boss portion 340 to the top end surface 342 of the boss portion 340.

[0093] In this embodiment, it is understood that the specific structural form of the boss portion 340 protruding from the inner wall of the adjusting member 300 can be flexibly set according to actual needs, as long as it is ensured that when the adjusting member 300 is rotated to the first position (such as Figure 4 and Figure 5 ), the third air inlet port 321 of the air passage 320 provided on the boss portion 340 and the first air outlet port 122 of the air inlet channel 120 are staggered and isolated from each other, and the third air outlet port 322 of the air passage 320 provided on the boss portion 340 and the second air inlet port 1241 of the air outlet channel 124 are staggered and isolated from each other, and when the adjusting member 300 is rotated to the second position (such as Figure 7 and Figure 8 ), the third air inlet port 321 of the air passage 320 provided on the boss portion 340 is connected to the first air outlet port 1232 of the air inlet channel 123, and the third air outlet port 322 of the air passage 320 provided on the boss portion 340 is connected to the second air inlet port 1241 of the air outlet channel 124. There is no specific limitation on this in the present embodiment.

[0094] Further, combined with Figures 1 to 8 、 Figure 10 and Figure 11 As shown, the outer shell 100 includes a bottom cover 140 and a top cover 150 with a vent hole 151. A mounting block 114 is protruded from the bottom of the liquid storage cup 110. The air inlet channel 123 is arranged in the mounting block 114 along a direction perpendicular to the height direction of the outer shell 100. The air outlet channel 124 is arranged between the inner peripheral wall of the outer shell 100 and the outer peripheral wall of the liquid storage cup 110 along the height direction of the outer shell 100. The bottom cover 140 is fixedly connected to the end of the mounting block 114 away from the liquid storage cup 110. In a specific implementation, as shown in FIG. Figure 2 、 Figure 3 、 Figure 6 、 Figure 10 and Figure 11As shown, the end of the mounting block 114 away from the liquid storage cup 110 is the lower end of the mounting block 114, that is, the bottom cover 140 can be fixedly connected to the lower end of the mounting block 114 by means of screws 143. The top cover 150 is provided on the end of the liquid storage cup 110 away from the air inlet channel 123, and the air vent 151 is correspondingly connected to the second air outlet port 1242 of the air outlet channel 124. The adjusting member 300 can be relatively rotatably clamped between the bottom of the liquid storage cup 110 and the bottom cover 140, and along the axial direction of the air inlet channel 123, one end of the mounting block 114 can relatively slide in contact with the inner side wall 341 of the boss portion 340, and the other end of the mounting block 114 can relatively slide in contact with the inner wall of the adjusting member 300. It should be noted that, as Figure 2 、 Figure 3 、 Figure 6 、 Figure 10 and Figure 11 As shown, the end of the liquid storage cup 110 away from the air inlet channel 123 is the upper end of the liquid storage cup 110 , that is, the top cover 150 is provided on the upper end of the liquid storage cup 110 .

[0095] It should be noted that the above “ Figure 5 "and" Figure 8 ” is a schematic diagram for the purpose of describing the positional relationship between the adjusting member 300 and the mounting block 114 when the adjusting member 300 is rotated to different positions. In actual application scenarios of the atomizer, the mounting block 114 and the liquid storage cup 110 may be an integrated structure to save manufacturing costs. Of course, in other embodiments of the present application, the mounting block 114 and the liquid storage cup 110 may also be separate structures, as long as the mounting block 114 is fixedly mounted to the bottom of the liquid storage cup 110 and the air inlet channel 123 is formed in the mounting block 114. The specific details are not limited here.

[0096] In this embodiment, it is understood that the shape of one end of the mounting block 114 matches the shape of the inner sidewall 341 of the boss portion 340, and the shape of the other end of the mounting block 114 matches the shape of the inner wall of the adjusting member 300. For example, the inner sidewall 341 of the boss portion 340 and the inner wall of the adjusting member 300 are both arc-shaped, and one end and the other end of the mounting block 114 are also configured to be arc-shaped accordingly. In this way, when the adjusting member 300 rotates relative to the outer shell 100, the two ends of the mounting block 114 will not hinder the rotation of the adjusting member 300, allowing the adjusting member 300 to rotate more smoothly.

[0097] Further, combined with Figure 2 、 Figure 5 、 Figure 8 and Figure 9As shown, the inner side wall of the adjusting member 300 is also provided with a first limiting rib 350 arranged along its own height direction. When the adjusting member 300 is rotated to the first position relative to the outer shell 100, the other end of the mounting block 114 (i.e., the end of the mounting block 114 away from the boss portion 340) abuts against the first limiting rib 350, so that the user can clearly feel whether the adjusting member 300 has been rotated to the desired first position. Specifically, when the adjusting member 300 has been rotated to the desired first position by the user, the user's hand can clearly feel that the adjusting member 300 can no longer continue to rotate in the same direction, without having to visually observe whether the first air inlet hole 310 of the adjusting member 300 is connected to the first air inlet port 1231 of the air inlet channel 123 to determine whether the adjusting member 300 has been rotated to the first position, thereby improving the user's experience.

[0098] Combine Figure 2 、 Figure 5 、 Figure 8 and Figure 9 As shown, the inner sidewall of the adjusting member 300 is also provided with a second limiting rib 360 arranged along its own height direction. When the adjusting member 300 is rotated to the second position relative to the outer shell 100, the other end of the mounting block 114 abuts the second limiting rib 360, so that the user can clearly sense whether the adjusting member 300 has been rotated to the desired second position. Specifically, when the adjusting member 300 has been rotated to the desired second position by the user, the user's hand can clearly sense that the adjusting member 300 can no longer continue to rotate in the same direction, without having to visually observe whether the first air inlet 310 of the adjusting member 300 is completely covered by the other end of the mounting block 114 to determine whether the adjusting member 300 has been rotated to the second position, thereby also improving the user experience.

[0099] Of course, it should be noted that the inner side wall of the adjusting member 300 is also provided with a first limiting rib 350 and a second limiting rib 360 arranged along the height direction thereof, and the first limiting rib 350 and the second limiting rib 360 are arranged at intervals along the circumference of the adjusting member 300. This arrangement allows the user to clearly sense whether the adjusting member 300 has been rotated to the desired first position or second position, thereby improving the user experience.

[0100] In this embodiment, it is understood that the shapes of the first limiting rib 350 and the second limiting rib 360 can be flexibly set according to actual needs. For example, the shapes of the first limiting rib 350 and the second limiting rib 360 can be set to strips or blocks, and this embodiment does not impose specific restrictions on this. It should be noted that in specific implementation, either the first limiting rib 350 or the second limiting rib 360 can be set, or both can be set at the same time. This can be determined according to actual use needs. This embodiment does not impose specific restrictions on this. For example, the inner wall of the adjusting member 300 is provided with a first limiting rib 350 and a second limiting rib 360 that are spaced apart along the circumference of the adjusting member 300, and the first air inlet 310 is located between the first limiting rib 350 and the second limiting rib 360.

[0101] Furthermore, in order to prevent the atomizer from leaking during use, refer to Figure 2 、 Figure 3 、 Figure 6 、 Figure 10 and Figure 11 As shown, the atomizer further includes a first sealing ring 400 embedded in the mounting block 114 and a second sealing ring 500 embedded in the end surface of the liquid storage cup 110 near the air inlet channel 123. The first sealing ring 400 is arranged around the first air outlet port 1232 of the air inlet channel 123 and is in close contact with the inner side wall surface 341 of the boss portion 340. The second sealing ring 500 is arranged around the second air inlet port 1241 of the air outlet channel 124 and is in close contact with the top end surface 342 of the boss portion 340, so that the aerosol generated by the atomizing core 200 can smoothly flow from the first air outlet port 1232 of the air inlet channel 123 into the air passage. The air passes through the third air inlet port 321 of the air passage 320, then flows into the second air inlet port 1241 of the air outlet channel 124 from the third air outlet port 322 of the air passage 320, and finally flows out from the second air outlet port 1242 of the air outlet channel 124 for inhalation by the user. In this way, the air tightness between the third air inlet port 321 of the air passage 320 and the first air outlet port 1231 of the air passage 123, as well as between the third air outlet port 322 of the air passage 320 and the second air inlet port 1241 of the air outlet channel 124 can be effectively improved, thereby improving the air tightness of the entire atomizer and preventing the atomizer from leaking when in use.

[0102] Furthermore, the liquid storage cup 110 can be made of a transparent material, such as glass, acrylic, etc. Thus, by setting the material of the liquid storage cup 110 to be a transparent material, it is convenient for the user to observe the remaining amount of the atomized liquid in the liquid storage cup 110.

[0103] In this embodiment, during specific implementation, the rotation stability of the adjusting member 300 can be improved through the following examples, specifically:

[0104] Example 1, refer to Figure 2 、 Figure 3 and Figure 6 As shown, the end surface of the bottom cover 140 facing the liquid storage cup 110 is provided with a first arc-shaped slide rail 141, and the first slide rail 141 and the boss portion 340 are relatively slidably arranged. In this example, the end surface of the bottom cover 140 facing the liquid storage cup 110 is the upper end surface of the bottom cover 140, that is, the upper end surface of the bottom cover 140 is provided with the first slide rail 141. The first slide rail 141 can play a certain radial limiting role and a circumferential guiding role, thereby improving the rotational stability of the adjustment member 300. It should be noted that in order to achieve the relatively slidable arrangement between the first slide rail 141 and the boss portion 340, in this embodiment, a first slide groove 343 is provided on the bottom end surface of the boss portion 340 opposite to the bottom cover 140, and the first slide rail 141 and the first slide groove 343 are clearance-matched.

[0105] Example 2, refer to Figure 10 As shown, a second slide rail 370 is protruding from the inner wall of the other end of the adjusting member 300 corresponding to the mounting block 114. The second slide rail 370 and the other end of the mounting block 114 are arranged to slide relative to each other. The second slide rail 370 can provide a certain axial limit and circumferential guidance, thereby improving the rotational stability of the adjusting member 300. It should be noted that to achieve the relative sliding cooperation between the second slide rail 370 and the other end of the mounting block 114, a second slide groove 115 is provided on the end surface of the other end of the mounting block 114 in this embodiment, and the second slide rail 370 and the second slide groove 115 have a clearance fit.

[0106] Example 3, refer to Figure 11 As shown, a first arc-shaped slide rail 141 is convexly provided on the end surface of the bottom cover 140 facing the liquid storage cup 110, that is, the first slide rail 141 is convexly provided on the upper end surface of the bottom cover 140, and the first slide rail 141 and the boss portion 340 can be slidably matched with each other; a second slide rail 370 is convexly provided on the inner wall of the other end of the adjusting member 300 corresponding to the mounting block 114, and the second slide rail 370 and the other end of the mounting block 114 can be slidably matched with each other, so that the rotation stability of the adjusting member 300 can be further improved.

[0107] It should be noted that, referring to Figures 1 to 3 、 Figure 6 、 Figure 10 and Figure 11As shown, the atomizer also includes a suction nozzle 600 mounted on the top of the liquid storage cup 110, and the internal cavity of the suction nozzle 600 is connected to the vent 151. In this way, by providing the suction nozzle 600, it is convenient for the user to use it for suction. In addition, the atomizer also includes an electrode assembly 142 installed on the bottom cover 140, the atomizing core 200 includes a bracket sleeve 210, a heating element 220 and a cylindrical liquid guide 230, a liquid inlet hole 211 is provided on the side wall of the bracket sleeve 210, the bracket sleeve 210 is installed in the air inlet channel 120 and the liquid inlet hole 211 is connected to the liquid storage cup 110, the liquid guide 230 is installed in the bracket sleeve 210 and the outer peripheral wall of the liquid guide 230 blocks the liquid inlet hole 211, the heating element 220 is connected to the inner wall of the liquid guide 230 and is electrically connected to the electrode assembly 142. It should be noted that one end of the electrode assembly 142 facing away from the heating element 220 is exposed on the bottom cover 140 so as to facilitate electrical connection of the electrode assembly 142 to an external power source (such as a host power source of the electronic atomization device).

[0108] The second structural design of the adjusting member 300 is shown in FIG. Figures 12 to 20 As shown, the second air inlet port 1241 of the air outlet channel 124 is connected to the first air outlet port 1231 of the air inlet channel 123, and the second air outlet port 1242 of the air outlet channel 124 is connected to the outside. The adjusting member 300 is annular and can be relatively rotatably installed in the air inlet channel 123 and partially exposed on the surface of the outer shell 100. The adjusting member 300 is provided with an air passage 320 in a direction perpendicular to the height direction of the outer shell 100. The air passage 320 has a third air inlet port 321 and a third air outlet port 322. A through hole 380 connected to the air passage 320 is provided on the end surface of the adjusting member 300 near the bottom of the liquid storage cup 110. The atomizer core 200 is connected to the through hole 380, wherein:

[0109] like Figure 14 、 Figure 17 and Figure 18 As shown, when the adjustment member 300 is rotated to the first position relative to the outer shell 100, the third air inlet port 321 of the air passage 320 and the first air inlet port 1231 of the air passage 123 are staggered and isolated from each other, and the third air outlet port 322 of the air passage 320 and the first air outlet port 1232 of the air passage 123 are staggered and isolated from each other, so that the air passage 320 is isolated from the outside world and the atomizer is in a ready-to-use state. In this way, the atomizer core 200 located in the air passage 123 is also isolated from the outside world, that is, the liquid storage cup 110 is also isolated from the outside world and is in a closed state, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 when the atomizer is not in use.

[0110] like Figure 15 、 Figure 19 and Figure 20 As shown, when the adjusting member 300 is rotated to the second position relative to the outer shell 100, the third air inlet port 321 of the air passage 320 is connected to the first air inlet port 1231 of the air inlet channel 123, and the third air outlet port 322 of the air passage 320 is connected to the first air outlet port 1232 of the air inlet channel 123, so that the first air inlet port 1231, the air passage 320, the first air outlet port 1232 and the air outlet channel 124 are connected in sequence, and the atomizer is in use.

[0111] It should be noted that, combined with Figure 14 、 Figure 17 and Figure 18 As shown, the above-mentioned "first position" refers to the position where the regulating member 300 rotates to the position where the third air inlet port 321 of the air passage 320 and the first air inlet port 1231 of the air inlet channel 123 are staggered and isolated from each other, and the third air outlet port 322 of the air passage 320 and the first air outlet port 1232 of the air inlet channel 123 are staggered and isolated. Figure 15 、 Figure 19 and Figure 20 As shown, the above-mentioned “second position” refers to the position where the regulating member 300 rotates to connect the air passage 320 thereon with the first air inlet port 1231 and the first air outlet port 1232 of the air inlet channel 123 .

[0112] Further, when implementing, refer to Figures 16 to 20 As shown, the atomizer further includes a bottom cover 140, which is fixedly connected to one end of the outer shell 100 near the air inlet channel 123, and a first fixing block 144 and a second fixing block 145 are convexly provided on the end surface of the bottom cover 140 near the liquid storage cup 110. The first fixing block 144 is provided with a second air inlet hole 1441 communicating with the first air inlet port 1231 of the air inlet channel 123, and the second fixing block 145 is provided with an air outlet hole 1451 communicating with the first air outlet port 1232 of the air inlet channel 123. The adjusting member 300 is relatively rotatably sandwiched between the first fixing block 144 and the second fixing block 145. It should be noted that, as Figure 17 and Figure 19 As shown, the end of the outer shell 100 near the air inlet passage 123 is the lower end of the outer shell 100, that is, the bottom cover 140 is fixedly connected to the lower end of the outer shell 100. The end surface of the bottom cover 140 near the liquid storage cup 110 is the upper end surface of the bottom cover 140, that is, the upper end surface of the bottom cover 140 is protrudingly provided with a first fixing block 144 and a second fixing block 145.

[0113] like Figure 17 and Figure 18As shown, when the adjustment member 300 is rotated to the first position relative to the outer shell 100, the third air inlet port 321 of the air passage 320 and the first air inlet port 1231 of the air inlet channel 123 are staggered and isolated from each other, and the third air outlet port 322 of the air passage 320 and the first air outlet port 1232 of the air inlet channel 123 are staggered and isolated from each other; Figure 19 and Figure 20 As shown, when the adjusting member 300 is rotated to the second position relative to the outer shell 100, the third air inlet port 321 of the air passage 320 is connected to the first air inlet port 1231 of the air passage 123 through the second air inlet hole 1441, and the third air outlet port 322 of the air passage 320 is connected to the first air outlet port 1232 of the air passage 123 through the air outlet hole 1451. In this way, by providing the first fixing block 144 and the second fixing block 145 on the bottom cover 140, the adjusting member 300 can be confined between the first fixing block 144 and the second fixing block 145, thereby preventing the position of the adjusting member 300 from shifting, which could result in the air passage 320 on the adjusting member 300 being unable to communicate with the second air inlet hole 1441 of the first fixing block 144 and the air outlet hole of the second fixing block 145, thereby ensuring normal use of the atomizer.

[0114] It should be noted that the bottom cover 140 in this embodiment is made of silicone, rubber or silicone rubber material. This not only improves the sealing effect of the bottom cover 140 on the air inlet channel 123 when the adjustment member 300 rotates to the first position relative to the outer shell 100, but also better isolates the liquid storage cup 110 from the outside world, thereby better preventing the leakage of the atomized liquid.

[0115] Further, refer to Figure 12 、 Figure 13 、 Figure 16 、 Figure 18 and Figure 20 As shown, the portion of the adjusting member 300 exposed on the surface of the outer shell 100 is provided with a plurality of grooves 390 arranged along its own height direction, so that when the user rotates the adjusting member 300 by hand, the user's fingers slip on the surface of the adjusting member 300 exposed on the outer shell 100, causing the adjusting member 300 to not rotate into place, thereby affecting the user's experience.

[0116] Furthermore, the portion of the outer shell 100 where the liquid storage cup 110 is provided can be made of a transparent material, such as glass, acrylic, etc. Thus, by setting the portion of the outer shell 100 where the liquid storage cup 110 is provided to be a transparent material, it is easier for the user to observe the remaining amount of atomized liquid in the liquid storage cup 110.

[0117] Correspondingly, if Figure 21As shown, the embodiment of the present invention further provides an electronic atomization device, which includes the atomizer in any one of the above embodiments (refer to Figures 1 to 20 Optionally, the electronic atomization device is applicable to fields such as electronic cigarette atomization and medical atomization, which are not limited here.
