[0063] Please refer to Figures 1 to 12 The utility model embodiment provides an atomizer, which comprises a shell body 100, an atomizing core 200 and an adjusting assembly 300.

[0064] The inside of the shell body 100 is provided with a liquid storage cup 110 and an airflow passage 120, the airflow passage 120 is arranged outside the liquid storage cup 110, and the airflow passage 120 has a first airflow port 121 and a second airflow port 122.

[0065] The atomizing core 200 is arranged at the bottom of the liquid storage cup 110 and communicates with the liquid storage cup 110, and the atomizing core 200 is located between the first airflow port 121 and the second airflow port 122.

[0066] The adjusting assembly 300 is movably arranged outside the shell body 100, and the adjusting assembly 300 has a first communication structure 310 and a second communication structure 320 which are in communication with the outside.

[0067] When the adjusting assembly 300 moves to the first position relative to the outer housing 100, the first communication structure 310 is misaligned with the first airflow port 121 and is isolated, and the second communication structure 320 is misaligned with the second airflow port 122 and is isolated, so that the atomization core 200 is isolated from the outside, and the atomizer is in a standby state.

[0068] When the adjusting assembly 300 moves to the second position relative to the outer housing 100, the first communication structure 310 is communicated with the first airflow port 121, and the second communication structure 320 is communicated with the second airflow port 122, so that the atomizer is in a use state.

[0069] With reference to Figure 3 , Figure 4 , and Figure 8 , Figure 9 , Figure 3 , and Figure 4 , the structural diagram of one embodiment in the present application is shown, Figure 8 , and Figure 9 , the structural diagram of another embodiment in the present application is shown. It should be noted that the above-mentioned "first position" refers to the position where the adjusting assembly 300 moves to the position where the first communication structure 310 is isolated from the first airflow port 121 of the airflow channel 120, and the second communication structure 320 is isolated from the second airflow port 122 of the airflow channel 120, so that the atomization core 200 located between the first airflow port 121 and the second airflow port 122 can be isolated from the outside. With reference to Figure 3 , Figure 5 , and Figure 8 , Figure 10 , Figure 3 , Figure 5 , the structural design of one embodiment in the present application is shown, Figure 8 , and Figure 10 , the structural design of another embodiment in the present application is shown. The above-mentioned "second position" refers to the position where the adjusting assembly 300 moves to the position where the first communication structure 310 is communicated with the first airflow port 121 of the airflow channel 120, and the second communication structure 320 is communicated with the second airflow port 122 of the airflow channel 120, so that the atomization core 200 located between the first airflow port 121 and the second airflow port 122 can be communicated with the outside.

[0070] In the embodiments of the present application, based on the above-mentioned structural design, when the atomizer is in a standby state, i.e., when the atomizer is not used, with reference to Figure 3 , and Figure 4 , and Figure 8 , and Figure 9In the illustrated embodiment, the adjustment component 300 can be moved relative to the outer casing 100 to a first position, such that the first connecting structure 310 on the adjustment component 300 is offset from and isolated from the first airflow port 121 of the airflow channel 120, and the second connecting structure 320 on the adjustment component 300 is offset from and isolated from the second airflow port 122 of the airflow channel 120. That is, the atomizing core 200 is isolated from the outside world, and the liquid storage cup 110 connected to the atomizing core 200 is also isolated from the outside world. Therefore, both the liquid storage cup 110 and the atomizing core 200 are in a closed state isolated from the outside world, thereby effectively preventing the risk of leakage of the atomizing liquid in the liquid storage cup 110 when the atomizer is not in use. Especially when the atomizer is in a non-use state such as high-altitude transportation, low temperature, or low pressure, the liquid reservoir 110 is in a closed state isolated from the outside world. Therefore, the internal pressure of the liquid reservoir 110 remains constant. That is, the air pressure inside the liquid reservoir 110 will not change due to the external environment of the atomizer, thus preventing leakage. When the atomizer needs to be used, continue to refer to... Figure 3 and Figure 5 The illustrated embodiments and Figure 8 and Figure 10 In the illustrated embodiment, the adjustment component 300 can be moved to a second position relative to the outer casing 100, so that the first connecting structure 310 on the adjustment component 300 is connected to the first airflow port 121 of the airflow channel 120, and at the same time, the second connecting structure 320 on the adjustment component 300 is connected to the second airflow port 122 of the airflow channel 120. That is, the atomizing core 200 is connected to the outside world through the first connecting structure 310, the airflow channel 120 and the second connecting structure 320, so that the atomizer can start to be used and work normally.

[0071] Furthermore, since the atomizing core 200 is located at the bottom of the reservoir cup 110, the atomizing core 200 can be directly electrically connected to the electrode located at the bottom of the atomizer, eliminating the hassle of leading out connecting pins from the atomizing core 200 and then connecting the connecting pins to the electrode at the bottom of the atomizer. This not only facilitates the electrical connection between the atomizing core 200 and the electrode at the bottom of the atomizer, but also simplifies the structure of the atomizing core 200, thereby reducing the manufacturing cost of the atomizing core 200.

[0072] Furthermore, in the structural design of some atomizers, the following is combined Figures 1 to 5As shown, the airflow channel 120 may include an air inlet channel 123 located at the bottom of the liquid storage cup 110 and an air outlet channel 124 located on the outside of the liquid storage cup 110. The air inlet channel 123 and the air outlet channel 124 are connected. The port in the air inlet channel 123 where external gas enters is the first airflow port 121 of the airflow channel 120, and the port in the air outlet channel 124 where gas flows out to the outside is the second airflow port 122 of the airflow channel 120.

[0073] In this embodiment, the airflow channel 120 can be L-shaped. Specifically, as shown in the figure... Figure 4 and Figure 5 As shown, the air outlet channel 124 is located on the left side of the liquid storage cup 110, and the air inlet channel 123 is located at the bottom of the liquid storage cup 110. Thus, the air outlet channel 124 and the air inlet channel 123 can be combined to form an L-shaped airflow channel 120. Of course, in other embodiments, the air outlet channel 124 is located on the right side of the liquid storage cup 110, and the air inlet channel 123 is located at the bottom of the liquid storage cup 110, so that the shape of the airflow channel 120 is... The specific form is not limited here.

[0074] Furthermore, based on the structural design of the L-shaped airflow channel 120 described above, such as Figures 3 to 5 As shown, the adjustment assembly 300 may include an adjustment ring 330 and a rotating cover 340. The adjustment ring 330 is rotatably mounted on the end of the housing 100 near the air intake channel 123, and the air intake channel 123 is located inside the adjustment ring 330. The adjustment ring 330 has a first through hole 331 that maintains communication with the outside, and the first through hole 331 is a first communication structure 310. The rotating cover 340 is rotatably mounted on the end of the housing 100 away from the air intake channel 123. The rotating cover 340 has a second through hole 341 that maintains communication with the outside, and the second through hole 341 is a second communication structure 320. In this embodiment, the first position includes a first closed position and a second closed position, and the second position includes a first communication position and a second communication position. It should be noted that, as Figure 4 and Figure 5 As shown, the end of the outer casing 100 closest to the air intake channel 123 is the lower end of the outer casing 100, and the end of the outer casing 100 furthest from the air intake channel 123 is the upper end of the outer casing 100. That is, in this embodiment, the adjusting ring 330 is rotatably mounted on the lower end of the outer casing 100, and the rotating cover 340 is rotatably mounted on the upper end of the outer casing 100.

[0075] like Figure 4As shown, when the adjusting ring 330 rotates relative to the outer shell 100 to the first closed position, and the rotating cover 340 rotates relative to the outer shell 100 to the second closed position, the first through hole 331 and the first airflow port 121 of the airflow channel 120 are misaligned and isolated from each other, and the second through hole 341 and the second airflow port 122 of the airflow channel 120 are misaligned and isolated from each other, so that the atomization core 200 is isolated from the outside, and the atomizer is in a standby state. Specifically, when the first through hole 331 and the first airflow port 121 of the airflow channel 120 are isolated, and the second through hole 341 and the second airflow port 122 of the airflow channel 120 are isolated, the air inlet channel 123 and the air outlet channel 124 are in a state of mutual isolation with the outside. In this way, the atomization core 200 in the airflow channel 120 and the liquid storage cup 110 are both in a closed state of mutual isolation with the outside, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 during non-use of the atomizer.

[0076] As shown, when the adjusting ring 330 rotates relative to the outer shell 100 to the first closed position, and the rotating cover 340 rotates relative to the outer shell 100 to the second closed position, the first through hole 331 and the first airflow port 121 of the airflow channel 120 are misaligned and isolated from each other, and the second through hole 341 and the second airflow port 122 of the airflow channel 120 are misaligned and isolated from each other, so that the atomization core 200 is isolated from the outside, and the atomizer is in a standby state. Specifically, when the first through hole 331 and the first airflow port 121 of the airflow channel 120 are isolated, and the second through hole 341 and the second airflow port 122 of the airflow channel 120 are isolated, the air inlet channel 123 and the air outlet channel 124 are in a state of mutual isolation with the outside. In this way, the atomization core 200 in the airflow channel 120 and the liquid storage cup 110 are both in a closed state of mutual isolation with the outside, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 during non-use of the atomizer. Figure 5 As shown, when the adjusting ring 330 rotates relative to the outer shell 100 to the first closed position, and the rotating cover 340 rotates relative to the outer shell 100 to the second closed position, the first through hole 331 and the first airflow port 121 of the airflow channel 120 are misaligned and isolated from each other, and the second through hole 341 and the second airflow port 122 of the airflow channel 120 are misaligned and isolated from each other, so that the atomization core 200 is isolated from the outside, and the atomizer is in a standby state. Specifically, when the first through hole 331 and the first airflow port 121 of the airflow channel 120 are isolated, and the second through hole 341 and the second airflow port 122 of the airflow channel 120 are isolated, the air inlet channel 123 and the air outlet channel 124 are in a state of mutual isolation with the outside. In this way, the atomization core 200 in the airflow channel 120 and the liquid storage cup 110 are both in a closed state of mutual isolation with the outside, thereby effectively preventing the risk of leakage of the atomized liquid in the liquid storage cup 110 during non-use of the atomizer.

[0077] It should be noted that the "first closed position" is the position of the adjusting ring 330 rotating to the first through hole 331 being isolated from the first airflow port 121 of the airflow channel 120, the "second closed position" is the position of the rotating cover 340 rotating to the second through hole 341 being isolated from the second airflow port 122 of the airflow channel 120, the "first communication position" is the position of the adjusting ring 330 rotating to the first through hole 331 being communicated with the first airflow port 121 of the airflow channel 120, and the "second communication position" is the position of the rotating cover 340 rotating to the second through hole 341 being communicated with the second airflow port 122 of the airflow channel 120.

[0078] In the embodiment, when the atomizer is used, the adjusting ring 330 can be first rotated to the first communication position relative to the outer shell 100, so that the first through hole 331 on the adjusting ring 330 is communicated with the first airflow port 121 of the airflow channel 120, and then the rotating cover 340 is rotated to the second communication position relative to the outer shell 100, so that the second through hole 341 on the rotating cover 340 is communicated with the second airflow port 122 of the airflow channel 120. In this way, the air outside can enter the air inlet channel 123 through the first through hole 331, and mix with the aerosol generated after the heating and atomization of the atomizer core 200, and under the suction of the user, the air outside forms a suction airflow, so that the aerosol is driven by the suction airflow to flow out of the outside in sequence through the air outlet channel 124 and the second through hole 341, for the user to smoke.

[0079] Of course, in other embodiments, when the atomizer is used, the rotating cover 340 can be first rotated, and then the adjusting ring 330 is rotated, so that the first through hole 331, the air inlet channel 123, the air outlet channel 124 and the second through hole 341 are communicated in sequence, and the specific place is not limited here.

[0080] Further, as shown in Figures 2 to 5 It should be noted that the "first closed position" is the position of the adjusting ring 330 rotating to the first through hole 331 being isolated from the first airflow port 121 of the airflow channel 120, the "second closed position" is the position of the rotating cover 340 rotating to the second through hole 341 being isolated from the second airflow port 122 of the airflow channel 120, the "first communication position" is the position of the adjusting ring 330 rotating to the first through hole 331 being communicated with the first airflow port 121 of the airflow channel 120, and the "second communication position" is the position of the rotating cover 340 rotating to the second through hole 341 being communicated with the second airflow port 122 of the airflow channel 120.

[0081] It should be noted that, asFigure 4 and Figure 5 As shown, the end of the liquid storage cup 110 away from the air intake channel 123 is the upper end of the liquid storage cup 110, and the end of the rotating shaft 140 away from the air intake channel 123 is the upper end of the rotating shaft 140. That is, in this embodiment, the top cover 130 is placed on the upper end of the liquid storage cup 110, and the upper end of the rotating shaft 140 passes through the mounting hole 131 and is placed in the groove 342.

[0082] In this embodiment, the connection between the top cover 130 and the liquid storage cup 110 can be a fixed connection or a detachable connection; the specific connection is not limited here.

[0083] Furthermore, combined Figures 2 to 5 As shown, the rotating cap 340 has a first limiting part 343 on its end face near the liquid storage cup 110, and the top cap 130 has a second limiting part 132 on its end face away from the air inlet channel 123, which is adapted to the first limiting part 343. It should be noted that, as... Figure 4 and Figure 5 As shown, the end face of the rotating cover 340 near the liquid storage cup 110 is the lower end face of the rotating cover 340, and the end face of the top cover 130 away from the air intake channel 123 is the upper end face of the top cover 130. That is, in this embodiment, the first limiting part 343 is provided on the lower end face of the rotating cover 340, and the second limiting part 132 is provided on the upper end face of the top cover 130.

[0084] In the embodiments of this application, the first limiting part 343 and the second limiting part 132 have the following two examples:

[0085] Example 1, combined with Figures 2 to 5As shown, the first limiting part 343 is a limiting protrusion 3431 protruding from an end face of the rotating cover 340 close to the liquid storage cup 110, and the second limiting part 132 is a limiting groove 1321 recessed from an end face of the top cover 130 away from the air inlet channel 123, that is, the first limiting part 343 is a limiting protrusion 3431 protruding from a lower end face of the rotating cover 340, and the second limiting part 132 is a limiting groove 1321 recessed from an upper end face of the top cover 130. Among them, the limiting protrusion 3431 is slidably arranged in the limiting groove 1321, and along the circumference of the rotating cover 340, the length of the limiting protrusion 3431 is less than the length of the limiting groove 1321. In this way, by arranging the limiting protrusion 3431 and the limiting groove 1321, not only can the rotating position of the rotating cover 340 be limited, but also can prevent the position of the rotating cover 340 from deviating during the rotation of the rotating cover 340, causing the atomized liquid in the liquid storage cup 110 to leak and the atomizer to be unable to be normally used and worked. For example, when the rotating cover 340 rotates relative to the outer shell 100 to the second closed position, the second through hole 341 cannot be completely offset from the second airflow port 122 of the airflow channel 120 to be isolated, so that the liquid storage cup 110 cannot be completely isolated from the outside, causing the risk of the atomized liquid in the liquid storage cup 110 leaking during the use of the atomizer; when the rotating cover 340 rotates relative to the outer shell 100 to the second communication position, the second through hole 341 cannot be communicated with the second airflow port 122 of the airflow channel 120, so that the atomizer cannot be normally used and worked.

[0086] In addition, since the length of the limiting protrusion 3431 is less than the length of the limiting groove 1321 along the circumference of the rotating cover 340, in this way, on the one hand, when the rotating cover 340 rotates relative to the outer shell 100, the limiting protrusion 3431 can also move in the limiting groove 1321, so that the rotation of the rotating cover 340 is more stable, and it is not easy to appear shaking or the position of the rotating cover 340 deviates; on the other hand, the length of the limiting groove 1321 can be set to limit the movement stroke of the rotating cover 340, that is, to limit the rotating position of the rotating cover 340. For example, when the rotating cover 340 rotates relative to the outer shell 100 in the clockwise direction, the limiting protrusion 3431 will also move in the limiting groove 1321 in the clockwise direction, when the limiting protrusion 3431 moves to the end of the slot wall of the limiting groove 1321 and cannot continue to move, the rotating cover 340 cannot rotate relative to the outer shell 100, and at this time, the rotating cover 340 is in the second communication position relative to the outer shell 100, in this way, in specific implementation, the user can rotate the rotating cover 340 in the clockwise direction, and when the rotating cover 340 cannot continue to rotate, it indicates that the rotating cover 340 is in the second communication position at this time, that is, the second through hole 341 is in communication with the second airflow port 122 of the airflow channel 120, so that the user can perceive that the rotating cover 340 has been rotated to the second communication position through the slot wall of the limiting groove 1321 resisting the limiting protrusion 3431, thereby saving the trouble of still needing to confirm whether the rotating cover 340 has been rotated to the second communication position. Similarly, when the rotating cover 340 rotates relative to the outer shell 100 in the counterclockwise direction, when the limiting protrusion 3431 moves to the slot wall of the other end of the limiting groove 1321 and cannot continue to move, it indicates that the rotating cover 340 has been rotated to the second closed position, so that the trouble of still needing to confirm whether the rotating cover 340 has been rotated to the second closed position can also be saved.

[0087] Example two, the first limiting part 343 is a limiting groove recessed on the end face of the rotating cover 340 close to the liquid storage cup 110, and the second limiting part 132 is a limiting protrusion protruding on the end face of the top cover 130 away from the air inlet channel 123, that is, the first limiting part 343 is a limiting groove recessed on the lower end face of the rotating cover 340, and the second limiting part 132 is a limiting protrusion protruding on the upper end face of the top cover 130. Among them, the limiting protrusion is slidably arranged in the limiting groove, and the length of the limiting protrusion is less than the length of the limiting groove along the circumference of the rotating cover 340. The limiting protrusion and the limiting groove provided in this example two have the same effect as the limiting protrusion 3431 and the limiting groove 1321 provided in example one, and the difference is only that the positions are not the same. For details, please refer to the description of example one, which will not be described here.

[0088] Further, in combination with Figures 2 to 5As shown, the outer shell 100 further comprises a bottom cover 150 and an air inlet pipe 160, the air inlet pipe 160 is installed at the bottom of the liquid storage cup 110, the atomizing core 200 is arranged in the air inlet pipe 160, the air inlet channel 123 is the inner space of the air inlet pipe 160, the bottom cover 150 is fixedly connected to the side of the air inlet pipe 160 away from the liquid storage cup 110, and the adjusting ring 330 is clamped between the bottom of the liquid storage cup 110 and the bottom cover 150 in a relatively rotatable manner. In this way, by arranging the air inlet pipe 160, the air inlet channel 123 can be arranged in the air inlet pipe 160, so that the trouble of arranging the air inlet channel 123 at the bottom of the liquid storage cup 110 can be avoided. It should be noted that in the embodiment, the side of the air inlet pipe 160 away from the liquid storage cup 110 is the lower side of the air inlet pipe 160, that is, the bottom cover 150 is fixedly connected to the lower side of the air inlet pipe 160.

[0089] In the embodiment, one end of the air inlet pipe 160 is provided with the first airflow port 121 of the airflow channel 120, and the other end of the air inlet pipe 160 is in communication with the port through which the airflow enters the air outlet channel 124. Since the adjusting ring 330 is clamped between the bottom of the liquid storage cup 110 and the bottom cover 150 in a relatively rotatable manner, the adjusting ring 330 can be rotated relative to the air inlet pipe 160 by an external force, so that the first through hole 331 on the adjusting ring 330 is arranged in a staggered or communicated manner with the one end of the air inlet pipe 160, that is, the first through hole 331 on the adjusting ring 330 can be arranged in a staggered or communicated manner with the first airflow port 121 of the airflow channel 120.

[0090] Further, in combination with Figures 1 to 5 As shown, the outer shell 100 further comprises a suction nozzle 170a fixedly connected to the rotating cover 340, and an air suction channel 171 (as shown in Figure 2 As shown, the second through hole 341 on the rotating cover 340 is in communication with the air suction channel 171. In this way, by arranging the suction nozzle 170a, the user can conveniently use the atomizer.

[0091] Further, in the structural design of some other atomizers, referring to Figures 6 to 10As shown, the outer housing 100 further comprises a bottom plate 101, which is arranged at the bottom of the outer housing 100 and is spaced apart from the bottom of the liquid storage cup 110 to form an air passing space 102. The air flow channel 120 comprises the air passing space 102, an air inlet channel 123 and an air outlet channel 124 arranged at opposite sides of the liquid storage cup 100. The air inlet channel 123 has a first air flow port 121 of the air flow channel 120 at an end away from the bottom plate 101. The air inlet channel 123 is in communication with one end of the air passing space 102 at an end close to the bottom plate 101. The air outlet channel 124 is in communication with the other end of the air passing space 102 at an end close to the bottom plate 101. The air outlet channel 124 has a second air flow port 122 of the air flow channel 120 at an end away from the bottom plate 101. In this way, the air inlet channel 123, the air outlet channel 124 and the air passing space 102 combine to form a U-shaped air flow channel 120. The first air flow port 121 and the second air flow port 122 of the U-shaped air flow channel 120 are both located at the top of the outer housing 100, i.e. at the upper end of the outer housing 100.

[0092] It should be noted that, as shown in Figure 9 and Figure 10 , the end of the air inlet channel 123 away from the bottom plate 101 is the upper end of the air inlet channel 123, and the end of the air inlet channel 123 close to the bottom plate 101 is the lower end of the air inlet channel 123. The end of the air outlet channel 124 close to the bottom plate 101 is the lower end of the air outlet channel 124, and the end of the air outlet channel 124 away from the bottom plate 101 is the upper end of the air outlet channel 124. That is, in the present embodiment, the upper end of the air inlet channel 123 is the first air flow port 121 of the air flow channel 120, the lower end of the air inlet channel 123 is in communication with one end of the air passing space 102, the lower end of the air outlet channel 124 is in communication with the other end of the air passing space 102, and the upper end of the air outlet channel 124 is the second air flow port 122 of the air flow channel 120.

[0093] Further, based on the structural design of the U-shaped air flow channel 120 described above, as shown in Figure 9 and Figure 10As shown, the adjusting assembly 300 can be a suction nozzle 170b which is slidably mounted on the top of the liquid storage cup 110. The suction nozzle 170b is provided with a first passage 172 and a second passage 173 which are spaced apart from each other. The first passage 172 is the first communication structure 310, and the second passage 172 is the second communication structure 320. The first passage 172 has a first air inlet port 1721 and a first air outlet port 1722 at two ends thereof. The first air inlet port 1721 is arranged on the outer side wall of the suction nozzle 170b and is in communication with the outside. The first air outlet port 1722 is arranged on the end face of the suction nozzle 170b which is close to the liquid storage cup 110. The second passage 173 has a second air inlet port 1731 and a second air outlet port 1732 at two ends thereof. The second air inlet port 1731 is arranged on the end face of the suction nozzle 170b which is close to the liquid storage cup 110, and is spaced apart from the first air outlet port 1722. The second air outlet port 1732 is arranged on the end face of the suction nozzle 170b which is away from the liquid storage cup 110 and is in communication with the outside. It should be noted that, as shown in Figure 9 and Figure 10 As shown, the end face of the suction nozzle 170b which is close to the liquid storage cup 110 is the lower end face of the suction nozzle 170b. That is, the first air outlet port 1722 and the second air inlet port 1731 are arranged on the lower end face of the suction nozzle 170b. The end face of the suction nozzle 170b which is away from the liquid storage cup 110 is the upper end face of the suction nozzle 170b. That is, the second air outlet port 1732 is arranged on the upper end face of the suction nozzle 170b and is in communication with the outside.

[0094] As shown in Figure 9 When the suction nozzle 170b is slid relative to the outer housing 100 to the first position, the first air outlet port 1722 of the first passage 172 is misaligned with the first airflow port 121 of the airflow channel 120, and the second air inlet port 1731 of the second passage 173 is misaligned with the second airflow port 122 of the airflow channel 120. As a result, the first passage 172 is isolated from the air inlet channel 123, and the second passage 173 is isolated from the air outlet channel 124. In this way, the atomizing core 200 arranged in the airflow channel 120 and the liquid storage cup 110 are isolated from the outside, and are in a closed state. Therefore, the risk of leakage of the atomizing liquid in the liquid storage cup 110 during non-use of the atomizer can be effectively prevented.

[0095] As shown in Figure 10As shown, when the suction nozzle 170b is slid relative to the outer housing 100 to the second position, the first air outlet port 1722 of the first channel 172 is in communication with the first airflow port 121 of the airflow channel 120, and the second air inlet port 1731 of the second channel 173 is in communication with the second airflow port 122 of the airflow channel 120, so that the first channel 172 is in communication with the air inlet channel 123, and the second channel 173 is in communication with the air outlet channel 124, and then the atomizing core 200 is in communication with the outside, and the atomizer is in a use state. Specifically, when the first channel 172 is in communication with the air inlet channel 123, and the second channel 173 is in communication with the air outlet channel 124, the air inlet channel 123 and the air outlet channel 124 are both in communication with the outside, so that the atomizing core 200 in the airflow channel 120 is also in communication with the outside. Since the atomizing core 200 is in communication with the liquid storage cup 110, when the atomizing core 200 is in communication with the outside, the liquid storage cup 110 is also in communication with the outside, so that the atomizer can be used and worked normally. Specifically, when the user sucks the atomizer, the air pressure in the airflow channel 120 decreases, while the air pressure in the liquid storage cup 110 remains constant, so that the air pressure in the airflow channel 120 is less than the air pressure in the liquid storage cup 110, forming a negative pressure. Therefore, the atomizing liquid in the liquid storage cup 110 flows into the atomizing core 200 under the action of the negative pressure, so that the atomizing core 200 can be heated and atomized, and then the atomizer can be used and worked normally.

[0096] In addition, by arranging the suction nozzle 170b, the user can conveniently suck and use the atomizer. Specifically, when using the atomizer, the user only needs to slide the suction nozzle 170b relative to the outer housing 100 to the second position, so that the first channel 172 is in communication with the air inlet channel 123 and the second channel 173 is in communication with the air outlet channel 124, and the user can suck the atomizer through the suction nozzle 170b.

[0097] Further, in combination with Figures 7 to 10 As shown, the outer housing 100 further comprises a sealing cover 103 arranged on the top of the liquid storage cup 110, and the first clamping part 175 is arranged on the end face of one end of the suction nozzle 170b close to the liquid storage cup 110, that is, the first clamping part 175 is arranged on the lower end face of the suction nozzle 170b, and the second clamping part 104 matched with the first clamping part 175 is arranged on the end face of one end of the sealing cover 103 close to the suction nozzle 170b. It should be noted that the first clamping part 175 and the second clamping part 104 are arranged on the end face of one end of the sealing cover 103 close to the suction nozzle 170b, that is, the second clamping part 104 is arranged on the upper end face of the sealing cover 103. Figure 7 and Figure 8 As shown, the end face of one end of the sealing cover 103 close to the suction nozzle 170b is the upper end face of the sealing cover 103, that is, the second clamping part 104 is arranged on the upper end face of the sealing cover 103.

[0098] In the embodiments of the present application, the first clamping part 175 and the second clamping part 104 have the following two examples:

[0099] Example one, in combination Figure 7 , Figure 8 , Figure 11 and Figure 12 , the first clamping portion 175 is a clamping groove 1751 concave on the end face of the suction nozzle 170b close to the liquid storage cup 110, and the second clamping portion 104 is a clamping hook 1041 convex on the end face of the sealing cover 103 close to the suction nozzle 170b, that is, the first clamping portion 175 is a clamping groove 1751 concave on the lower end face of the suction nozzle 170b, and the second clamping portion 104 is a clamping hook 1041 convex on the upper end face of the sealing cover 103. Among them, the clamping hook 1041 is slidably arranged in the clamping groove 1751, and the length L1 of the clamping hook 1041 is less than the length L2 of the clamping groove 1751 along the sliding direction of the suction nozzle 170b (as shown in Figure 11 and Figure 12 ). In this way, by setting the clamping hook 1041 and the clamping groove 1751, not only can the sliding position of the suction nozzle 170b be limited, but also can prevent the position of the suction nozzle 170b from deviating during the sliding process of the suction nozzle 170b, causing the atomized liquid in the liquid storage cup 110 to leak and the atomizer to be unable to be normally used and worked. For example, when the suction nozzle 170b slides to the first position relative to the outer shell 100, the first air outlet port 1722 of the first channel 172 cannot be completely offset from the first airflow port 121 of the airflow channel 120, and the second air inlet port 1731 of the second channel 173 cannot be completely offset from the second airflow port 122 of the airflow channel 120, thereby causing the liquid storage cup 110 to be unable to be completely isolated from the outside, resulting in the risk of the atomized liquid in the liquid storage cup 110 leaking during the process of not using the atomizer; when the suction nozzle 170b slides to the second position relative to the outer shell 100, the first air outlet port 1722 of the first channel 172 cannot be in communication with the first airflow port 121 of the airflow channel 120, and the second air inlet port 1731 of the second channel 173 cannot be in communication with the second airflow port 122 of the airflow channel 120, thereby causing the atomizer to be unable to be normally used and worked.

[0100] In addition, as Figure 11 and Figure 12As shown, since the length L1 of the hook 1041 is less than the length L2 of the slot 1751 along the sliding direction of the nozzle 170b, this setting ensures that, on the one hand, when the nozzle 170b slides relative to the outer casing 100, the hook 1041 can also move in the slot 1751, making the sliding of the nozzle 170b more stable and less prone to shaking or displacement of the nozzle 170b; on the other hand, by setting the length L2 of the slot 1751, the nozzle 170b can be more stable. The sliding stroke of nozzle 170b is limited, that is, the sliding position of nozzle 170b is limited. For example, when nozzle 170b slides to the right relative to housing 100, hook 1041 will also move to the right within slot 1751. When hook 1041 moves to the point where it is blocked by the slot wall at one end of slot 1751 and cannot continue to move, nozzle 170b also cannot continue to slide to the right relative to housing 100. At this time, nozzle 170b is in a second position relative to housing 100 (e.g., Figure 11 (As shown). Thus, in practical implementation, the user can drive the nozzle 170b to the right. When the nozzle 170b can no longer slide, it indicates that the nozzle 170b is in the second position. That is, the first air outlet port 1722 of the first channel 172 is connected to the first airflow port 121 of the airflow channel 120, and simultaneously, the second air inlet port 1731 of the second channel 173 is connected to the second airflow port 122 of the airflow channel 120. In this way, the user can sense that the nozzle 170b has slid to the second position by the hook 1041 being blocked by the groove wall of the slot 1751, thus eliminating the need to confirm whether the nozzle 170b has slid to the second position. Similarly, when the nozzle 170b slides to the left relative to the outer casing 100, if the hook 1041 moves to the point where it is blocked by the groove wall at the other end of the slot 1751 and cannot continue to move, it indicates that the nozzle 170b has slid to the first position (e.g., ...). Figure 12 As shown in the figure, this also eliminates the need to check whether the nozzle 170b has slid to the first position.

[0101] In Example 2, the first engaging portion 175 is a hook protruding from the end face of the nozzle 170b near the liquid reservoir 110, and the second engaging portion 104 is a groove recessed from the end face of the sealing cap 103 near the nozzle 170b. In other words, the first engaging portion 175 is a hook protruding from the lower end face of the nozzle 170b, and the second engaging portion 104 is a groove recessed from the upper end face of the sealing cap 103. The hook is slidably disposed within the groove, and along the sliding direction of the nozzle 170b, the length of the hook is less than the length of the groove. The functions of the hook and groove in Example 2 are the same as those of the hook 1041 and groove 1751 in Example 1, the only difference being their placement. For details, please refer to the description in Example 1; further elaboration is omitted here.

[0102] Further, in combination with Figures 7 to 10 As shown in the figure, the sealing cover 103 has oppositely arranged top surface 1031, bottom surface 1032 and side wall surface 1033 arranged between the top surface 1031 and the bottom surface 1032, and the first air flow port 121 corresponding to the air flow channel 120 is provided with an air passing channel 105, and the two ends of the air passing channel 105 are respectively a third air inlet port 1051 and a third air outlet port 1052, the third air inlet port 1051 is arranged on the top surface 1031, and the third air outlet port 1052 penetrates the bottom surface 1032 and the side wall surface 1033 at the same time and communicates with the first air flow port 121 of the air flow channel 120.

[0103] As shown in the figure, Figure 9 When the suction nozzle 170b slides to the first position relative to the outer shell 100, the first air outlet port 1722 of the first channel 172 is misaligned with the third air inlet port 1051 of the air passing channel 105, so that the first channel 172 is isolated from the air passing channel 105 and the air inlet channel 123.

[0104] As shown in the figure, Figure 10 When the suction nozzle 170b slides to the second position relative to the outer shell 100, the first air outlet port 1722 of the first channel 172 communicates with the third air inlet port 1051 of the air passing channel 105, so that the first channel 172 communicates with the air inlet channel 123 through the air passing channel 105.

[0105] In this embodiment, based on the above structure design, by arranging the sealing cover 103 with the air passing channel 105, on the one hand, the top of the liquid storage cup 110 can be sealed to prevent the atomized liquid in the liquid storage cup 110 from adhering to the suction nozzle 170b or leaking from the suction nozzle 170b to the outside, on the other hand, when the suction nozzle 170b slides to the first position relative to the outer shell 100, the sealing performance between the first channel 172 and the air inlet channel 123 can be enhanced, further reducing the risk of leakage of the atomized liquid in the liquid storage cup 110, and when the suction nozzle 170b slides to the second position relative to the outer shell 100, that is, when the first channel 172 and the air inlet channel 123 are communicated, the air tightness between the first channel 172 and the air inlet channel 123 can be increased, avoiding the situation of air leakage when the user uses the atomizer.

[0106] Correspondingly, as shown in the figure, Figure 13 The utility model embodiment further provides an electronic atomization device, which comprises the atomizer in any one of the above embodiments (such as Figures 1 to 12 As shown in the figure). Optionally, the electronic atomization device is suitable for electronic cigarette atomization, medical atomization and the like, and is not limited herein.

[0107] In the embodiment, the electronic atomization device has the same technical effects as the atomizer, and details are not described herein.

[0108] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
