[0040] 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 the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0041] See also Figure 1 and Figure 2 An embodiment of the present application provides an atomization device, including an atomizer and a battery assembly 300. The battery assembly 300 is electrically connected to the atomizer. The battery assembly 300 is used to power the atomizer. The atomizer is used to heat the atomization medium and atomize it to form an aerosol after being powered on.

[0042] See also Figures 1 to 3 , the atomizer provided in the embodiment of the present application is now described.

[0043] The atomizer includes an atomizer assembly 100 and a nozzle assembly 200. The atomizer assembly 100 includes an air outlet pipe 111. The peripheral side wall of the air outlet pipe 111 has an air outlet 1111. At least a portion of the nozzle assembly 200 and the air outlet pipe 111 can generate relative movement to switch the connection state between the air outlet 1111 and the external atmosphere.

[0044] The atomizing assembly 100 is used to heat and atomize the atomizing medium to generate an aerosol. The outlet pipe 111 is a pipe for discharging the aerosol. The outlet port 1111 is formed on the peripheral side wall of the outlet pipe 111 and is used to discharge the aerosol in the outlet pipe 111 outward.

[0045] The circumferential side wall of the air outlet pipe 111 has an air outlet 1111 , which means that the air outlet 1111 is formed on the side wall of the air outlet pipe 111 along the circumferential direction.

[0046] At least a portion of the nozzle assembly 200 and the air outlet pipe 111 are capable of relative movement to switch the connection between the air outlet 1111 and the outside atmosphere. This means that at least a portion of the nozzle assembly 200 and the air outlet pipe 111 are driven to generate relative movement, so that the air outlet 1111 can be connected and disconnected from the outside atmosphere. When the air outlet 1111 is connected to the outside atmosphere, aerosol can be discharged outward through the air outlet 1111. When the air outlet 1111 is disconnected from the outside atmosphere, the air outlet 1111 is sealed by the nozzle assembly 200, thereby preventing odor from escaping.

[0047] Furthermore, at least a portion of the nozzle assembly 200 and the air outlet pipe 111 can generate relative motion, which means that the entire nozzle assembly 200 and the air outlet pipe 111 can generate relative motion, or a portion of the nozzle assembly 200 can generate relative motion with the air outlet pipe 111. Furthermore, the relative motion can be relative rotation, relative movement, or a combination of rotation and movement.

[0048] The atomizer in the embodiment of the present application is provided with an air outlet 1111 on the peripheral side wall of the air outlet pipe 111, and at least a portion of the nozzle assembly 200 is capable of relative movement with the air outlet pipe 111 to switch the connection state between the air outlet 1111 and the external atmosphere, that is, it is capable of driving at least a portion of the structure of the nozzle assembly 200 to generate relative movement with the air outlet pipe 111 so that the air outlet 1111 is connected to the external atmosphere or disconnected from the external atmosphere. Specifically, when in use, the air outlet 1111 can be connected to the external atmosphere, and the aerosol generated by the atomizing assembly 100 is discharged through the air outlet 1111 for inhalation by the user. When not in use, the air outlet 1111 can be disconnected from the external atmosphere to prevent the odor of the atomizing assembly 100 from escaping.

[0049] In addition, in the present application, by setting the air outlet pipe 111 and setting the air outlet 1111 on the peripheral side wall of the air outlet pipe 111, the connection state between the air outlet 1111 and the external atmosphere can be switched by the relative movement of the suction nozzle assembly 200 and the air outlet pipe 111, without the need to additionally set up a blocking piece to seal the air outlet 1111, making it convenient to switch the connection state of the air outlet 1111.

[0050] In some embodiments, at least a portion of the nozzle assembly 200 can rotate relative to the air outlet pipe 111 to switch the connection between the air outlet 1111 and the outside atmosphere. Specifically, the entire nozzle assembly 200 can be rotated relative to the air outlet pipe 111 to switch between a connection and a disconnection between the air outlet 1111 and the outside atmosphere; or a portion of the nozzle assembly 200 can be rotated relative to the air outlet pipe 111 to switch between a connection and a disconnection between the air outlet 1111 and the outside atmosphere.

[0051] In some embodiments, see Figure 3 and Figure 4 The suction nozzle assembly 200 includes a suction nozzle 210 and a suction nozzle seal 220; the suction nozzle 210 has a suction port 211 connected to the external atmosphere, and the suction nozzle seal 220 has a connecting groove 221 connected to the suction port 211; at least the suction nozzle seal 220 can move relative to the air outlet pipe 111 so that the connecting groove 221 is connected to the air outlet 1111, or the suction nozzle seal 220 blocks the air outlet 1111.

[0052] Specifically, the nozzle seal 220 is movable relative to the air outlet pipe 111 and has a first position and a second position. When the nozzle seal 220 is in the first position relative to the air outlet pipe 111, the connecting groove 221 is in communication with the air outlet 1111, and the connecting groove 221 is in communication with the suction port 211, and the suction port 211 is in communication with the external atmosphere, thereby achieving communication between the air outlet 1111 and the external atmosphere, and the aerosol generated by the atomizer assembly 100 can be guided outward through the air outlet 1111, the connecting groove 221, and the suction port 211 in sequence. When the nozzle seal 220 is in the second position relative to the air outlet pipe 111, the air outlet 1111 is blocked by the nozzle seal 220, and the air outlet 1111 is isolated from the external atmosphere, thereby preventing the odor in the atomizer assembly 100 from escaping. Moreover, due to the sealing effect of the nozzle seal 220, a better odor prevention effect is achieved.

[0053] In some embodiments, see Figure 3 The nozzle seal 220 is fixedly connected to the nozzle 210, and the nozzle seal 220 is movably connected to the air outlet pipe 111. Since the nozzle seal 220 is fixedly connected to the nozzle 210, when switching the connection state of the air outlet 1111, the nozzle assembly 200 can be moved relative to the air outlet pipe 111 as a whole, resulting in a simple structure and easy operation. Furthermore, since the nozzle seal 220 is fixedly connected to the nozzle 210, the connecting groove 221 and the suction port 211 are always in a connected state. When switching the state, it is only necessary to switch the connection state between the connecting groove 222 and the air outlet 1111, which is easy to operate.

[0054] In some embodiments, see Figure 3The nozzle seal 220 is rotatably sleeved on the outside of the air outlet pipe 111, and the nozzle 210 is fixedly sleeved on the outside of the nozzle seal 220. When switching states, the nozzle seal 220 and the nozzle 210 are rotated relative to the air outlet pipe 111 with the air outlet pipe 111 as the rotation axis, so that the connecting groove 221 of the nozzle seal 220 is directly connected to the air outlet 1111, or the side wall of the nozzle seal 220 blocks the air outlet 1111. During operation, it is only necessary to rotate the nozzle assembly 200 and the air outlet pipe 111 relative to each other. In addition, since the air outlet pipe 111 is generally fixed relative to the main body of the atomizer assembly 100, that is, the nozzle assembly 200 and the atomizer assembly 100 are relatively rotated to achieve state switching, which is convenient to operate.

[0055] In some embodiments, see Figure 4 The atomizer also includes a limiting structure 400, which is used to limit the relative movement between the nozzle assembly 200 and the air outlet pipe 111, thereby confining the nozzle assembly 200 to a first position or a second position. The limiting structure 400 allows the air outlet 1111 to remain connected to the outside atmosphere, facilitating inhalation by the user; at the same time, it can also disconnect the air outlet 1111 from the outside atmosphere, effectively preventing odor from escaping.

[0056] In some embodiments, see Figures 3 to 5 The limiting structure 400 includes two first limiting portions 410 and two second limiting portions 420. The two first limiting portions 410 are respectively formed on the end surface of the nozzle assembly 200 facing the atomizer assembly 100 and are symmetrically arranged along the circumferential direction. The two second limiting portions 420 are respectively formed on the end surface of the atomizer assembly 100 facing the nozzle assembly 200 and are symmetrically arranged along the circumferential direction. When the nozzle assembly 200 and the air outlet pipe 111 rotate relative to each other to the first position, the two first limiting portions 410 respectively cooperate with the two second limiting portions 420 in a concave-convex manner to prevent the nozzle assembly 200 and the air outlet pipe 111 from rotating relative to each other. When the nozzle assembly 200 and the air outlet pipe 111 rotate relative to each other to the second position, the two first limiting portions 410 exchange positions, and the two first limiting portions 410 can also respectively cooperate with the two second limiting portions 420 in a concave-convex manner to prevent the nozzle assembly 200 and the air outlet pipe 111 from rotating relative to each other.

[0057] It should be noted that the concave-convex fit between the first limiting portion 410 and the second limiting portion 420 can, to a certain extent, prevent the nozzle assembly 200 and the air outlet pipe 111 from rotating relative to each other, thereby preventing the user from accidentally touching the nozzle assembly 200 and causing the state to switch. However, during normal use, the user can use external force to overcome the limiting resistance between the first limiting portion 410 and the second limiting portion 420 to drive the nozzle assembly 200 to rotate. In addition, the number of first limiting portions 410 can be three or more, and the number of second limiting portions 420 can also be three or more. When the nozzle assembly 200 is rotated to the first position and the second position, each first limiting portion 410 and each second limiting portion 420 can have a one-to-one corresponding concave-convex fit.

[0058] As an example, see Figures 3 to 5 The two first position-limiting portions 410 are arcuate grooves formed on the end surface of the nozzle assembly 200 facing the atomizer assembly 100, and the two arcuate grooves are respectively formed on the nozzle seal 220; the two second position-limiting portions 420 are arcuate protrusions formed on the end surface of the atomizer assembly 100 facing the nozzle assembly 200, and the two arcuate protrusions correspond to the two arcuate grooves in a one-to-one manner to form a position limit. Of course, in other examples, the arcuate grooves can also be formed on the nozzle 210; or the arcuate protrusions can also be formed on the air outlet pipe 111.

[0059] As another example, the two first limiting portions 410 are respectively arc-shaped protrusions formed on the end surface of the suction nozzle assembly 200 facing the atomizer assembly 100, and the two arc-shaped protrusions are respectively formed on the suction nozzle seal 220; the two second limiting portions 420 are respectively arc-shaped grooves formed on the end surface of the atomizer assembly 100 facing the suction nozzle assembly 200.

[0060] In some embodiments, see Figure 1 The atomizer assembly 100 has a first identification portion 113 on its surface, and the nozzle assembly 200 has a second identification portion 215 on its surface. When the first identification portion 113 and the second identification portion 215 are arranged vertically opposite each other, the air outlet 1111 is connected to the outside atmosphere. When the first identification portion 113 and the second identification portion 215 are located on opposite sides along the circumferential direction, the air outlet 1111 is disconnected from the outside atmosphere. The arrangement of the first identification portion 113 and the second identification portion 215 facilitates the user to quickly identify the usage status of the atomizer.

[0061] As an example, the first identification portion 113 is a triangle with its tip facing the nozzle assembly 200, and the second identification portion 215 is a triangle with its tip facing the atomizer assembly 100. In other embodiments, the first identification portion 113 and the second identification portion 215 may also be arrows, scale lines, characters, or irregular shapes, etc., which are not limited here.

[0062] In some embodiments, see Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The outer peripheral wall of the air outlet pipe 111 is convexly provided with a limiting ring 1112, and the limiting ring 1112 has a first side 1113 and a second side 1114 arranged opposite to each other. The inner peripheral wall of the suction nozzle 210 is provided with a block 212 and a limiting rib 213, and the suction nozzle seal 220 has a through groove 222 corresponding to the position of the block 212. The block 212 is clamped to the second side 1114 via the through groove 222, and the suction nozzle seal 220 is axially abutted between the first side 1113 and the limiting rib 213. The above arrangement can limit the suction nozzle 210 and the suction nozzle seal 220 in the axial direction, and both can rotate relative to the air outlet pipe 111.

[0063] In some embodiments, see Figure 3 、 Figure 6 and Figure 7 The inner wall of the suction nozzle 210 is provided with a circumferential limiting protrusion 214, and the suction nozzle seal 220 is provided with a circumferential limiting groove 223. The circumferential limiting protrusion 214 and the circumferential limiting groove 223 cooperate with each other to limit the relative rotation of the suction nozzle seal 220 and the suction nozzle 210, that is, to enable the suction nozzle seal 220 and the suction nozzle 210 to rotate synchronously.

[0064] Specifically, the circumferential limiting groove 223 has two limiting surfaces 2231 arranged at circumferential intervals, and each circumferential limiting groove 223 has two circumferential limiting protrusions 214. The two circumferential limiting protrusions 214 respectively abut against the two limiting surfaces 2231, thereby realizing circumferential limitation of the nozzle seal 220 and the nozzle 210.

[0065] Optionally, the number of the circumferential limiting grooves 223 may be one or more.

[0066] In some embodiments, see Figure 6 The outer circumferential wall of the nozzle seal 220 is provided with a sealing rib 224, which is used to elastically abut the inner circumferential wall of the nozzle 210. The provision of the sealing rib 224, on the one hand, can form a sealed connection between the nozzle seal 220 and the nozzle 210, preventing the airflow directed from the air outlet 1111 to the connecting groove 221 from flowing out through the gap between the nozzle seal 220 and the nozzle 210. On the other hand, it can also ensure that the nozzle seal 220 and the nozzle 210 are interference-fitted, ensuring that the nozzle seal 220 and the nozzle 210 can rotate synchronously.

[0067] In some embodiments, see Figure 3 The top opening of the air outlet pipe 111 is provided, and the nozzle seal 220 blocks the opening. The provision of the top opening facilitates insertion of the upper mold during injection molding to prevent the air outlet pipe 111 from tilting.

[0068] In some embodiments, see Figure 5 and Figure 8 The atomizer assembly 100 further includes an air inlet 112, and at least a portion of the nozzle assembly 200 and the air outlet pipe 111 can generate relative movement to switch the connection state between the air outlet 1111 and the external atmosphere, and to switch the connection state between the air inlet 112 and the external atmosphere.

[0069] Specifically, the connection state between the air outlet 1111 and the air inlet 112 and the external atmosphere can be switched simultaneously by driving at least part of the structure of the nozzle assembly 200 to move relative to the air outlet pipe 111. For example, in the first position, the air inlet 112 is connected to the external atmosphere, and the air outlet 1111 is also connected to the external atmosphere, so that the atomizer can work normally; in the second position, the air inlet 112 is disconnected from the external atmosphere, and the air outlet 1111 is also disconnected from the external atmosphere, so that the atomizer assembly 100 is completely isolated from the external atmosphere to prevent the odor from escaping. It is understandable that in other embodiments of the present application, the air inlet 112 can also be blocked by an additional blocking member to prevent the odor from escaping from the air inlet 112.

[0070] In some embodiments, see Figure 5 The air outlet pipe 111 is convexly arranged on the end surface of the atomizer assembly 100 facing the nozzle assembly 200; the air inlet 112 is concavely arranged on the end surface of the atomizer assembly 100 facing the nozzle assembly 200. By relative movement between at least part of the structure of the nozzle assembly 200 and the air outlet pipe 111, the opening and closing of the air inlet 112 and the air outlet 1111 are achieved. Specifically, by forming the air inlet 112 on the end surface of the atomizer assembly 100 facing the nozzle assembly 200, it is convenient for the nozzle assembly 200 to simultaneously switch the connection state of the air inlet 112 and the air outlet 1111 when it moves. Of course, in other embodiments, when the size of the nozzle assembly 200 is large, the air inlet 112 can also be formed on the peripheral side wall of the atomizer assembly 100.

[0071] In some embodiments, see Figure 4 、 Figure 6 and Figure 8 The nozzle assembly 200 has a notch 225 that communicates with the outside atmosphere. At least a portion of the nozzle assembly 200 and the air outlet pipe 111 can rotate relative to each other to switch the communication state between the notch 225 and the air inlet 112. Specifically, when the notch 225 and the air inlet 112 are arranged directly opposite each other, the air inlet 112 communicates with the outside atmosphere through the notch 225. When the notch 225 and the air inlet 112 are circumferentially offset, the air inlet 112 is blocked by the nozzle assembly 200, specifically by the nozzle seal 220, thereby preventing odor from escaping.

[0072] In some embodiments, see Figure 8 The nozzle assembly 200 includes a nozzle 210 and a nozzle seal 220. A notch 225 is recessed on the side of the nozzle seal 220 facing the atomizer assembly 100 and extends through the outer wall of the nozzle seal 220. A longitudinal airflow gap 800 is defined between the nozzle 210 and the atomizer assembly 100, allowing external air to flow toward the air inlet 112 through the airflow gap 800 and the notch 225.

[0073] In some embodiments, see Figure 2 、 Figure 3 、 Figure 8 and Figure 9 The atomization assembly 100 includes an air inlet channel 121, an atomization channel 131 and a first connecting channel 141. The air inlet channel 121 and the atomization channel 131 are spaced apart in the transverse direction. The air inlet channel 121 extends from the air inlet 112 to the first connecting channel 141, and the atomization channel 131 extends from the first connecting channel 141 to the air outlet 1111.

[0074] Among them, the transverse direction refers to the direction perpendicular to the longitudinal direction of the atomizer assembly 100, and for the sake of convenience, it is referred to as transverse and longitudinal. The air inlet channel 121 and the atomization channel 131 are distributed in a transverse interval, and the air inlet channel 121 and the atomization channel 131 may both extend in the longitudinal direction and be arranged in a transverse interval. Alternatively, the air inlet channel 121 has a tendency to extend in the longitudinal direction, but does not strictly extend in the longitudinal direction, and may be bent, folded, or extended in a direction inclined to the longitudinal direction, and the atomization channel 131 may also be bent, folded, or extended in a direction inclined to the longitudinal direction.

[0075] In this embodiment, the air inlet channel 121 and the atomization channel 131 are respectively provided, and the air inlet channel 121 and the atomization channel 131 are arranged at intervals along the horizontal direction, so that the air inlet 112 and the air outlet 1111 are both provided at one end of the atomization assembly 100 facing the nozzle assembly 200, so that the nozzle assembly 200 can move to synchronously realize the state switching of the air inlet 112 and the air outlet 1111.

[0076] In some embodiments, see Figure 2 、 Figure 8 and Figure 9The atomizer assembly 100 includes a liquid reservoir 120, an atomizer seat 130, a bottom cover 150, and a bottom seal 140; an atomizer channel 131 is provided through the atomizer seat 130, the liquid reservoir 120 is sleeved on the outside of the atomizer seat 130, and the liquid reservoir 120 and the atomizer seat 130 enclose a liquid storage cavity. The bottom cover 150 is provided on the bottom of the liquid reservoir 120 and the atomizer seat 130, and the bottom seal 140 is sealed between the bottom cover 150 and the liquid reservoir 120 and the atomizer seat 130. The air inlet channel 121 is formed in the liquid reservoir 120, and the first connecting channel 141 is formed on the side of the bottom seal 140 away from the air inlet 112. Among them, by forming a connection between the air inlet channel 121 and the atomizer channel 131 at the bottom seal 140, the connection sealing can be ensured.

[0077] In some embodiments, see Figure 9 The bottom seal 140 has a central hole 142 and a first through hole 143 . The first through hole 143 is connected to the air inlet channel 121 , and the central hole 142 is connected to the atomization channel 131 . The first connecting channel 141 is formed on the side of the bottom seal 140 away from the nozzle assembly 200 .

[0078] In some embodiments, see Figure 2 and Figure 8 The atomizer assembly 100 also has a negative pressure channel 122, which is connected to the airflow sensor 330; at least part of the nozzle assembly 200 and the air outlet pipe 111 can move relative to each other to switch the connection state between the air outlet 1111 and the external atmosphere, and to switch the connection state between the negative pressure channel 122 and the air outlet 1111.

[0079] Specifically, in the first position, the air outlet 1111 is connected to the external atmosphere, and the negative pressure channel 122 of the negative pressure channel 122 is connected to the air outlet 1111. The airflow sensor 330 can detect the negative pressure to start the nebulizer, and the aerosol generated by the nebulizer can be discharged outward through the air outlet 1111.

[0080] In the second position, the air outlet 1111 is disconnected from the external atmosphere, and the negative pressure channel 122 of the negative pressure channel 122 is disconnected from the air outlet 1111, that is, the air outlet 1111 and the negative pressure channel 122 can be closed at the same time, which can avoid accidental startup and odor escape.

[0081] In some embodiments, see Figure 3 、 Figure 6 and Figure 8The suction nozzle assembly 200 has a suction port 211 connected to the external atmosphere and a second connecting channel 230 connected to the suction port 211. At least part of the suction nozzle assembly 200 and the air outlet pipe 111 can move relative to each other to switch the connection state between the air outlet 1111 and the suction port 211, and to switch the connection state between the negative pressure channel 122 and the second connecting channel 230.

[0082] The negative pressure channel 122 is connected to the suction port 211 via the second connecting channel 230 , so that negative pressure is generated in the negative pressure channel 122 when the user inhales, so that the airflow sensor 330 detects the airflow and starts the atomizer.

[0083] In some embodiments, see Figure 5 and Figure 8 The inlet end 1221 of the negative pressure channel 122 is formed on the end surface of the atomizer assembly 100 facing the nozzle assembly 200. By moving at least a portion of the nozzle assembly 200 relative to the air outlet pipe 111, the second connecting channel 230 of the nozzle assembly 200 is connected to the negative pressure channel 122, or the nozzle assembly 200 blocks the negative pressure channel 122.

[0084] In some embodiments, see Figure 8 The negative pressure channel 122 is arranged parallel to the air inlet channel 121 and spaced apart. The negative pressure channel 122 and the air inlet 112 are both formed on the end surface of the atomizer assembly 100 facing the nozzle assembly 200. When at least part of the nozzle assembly 200 is movable, the air inlet 112 and the negative pressure channel 122 can be blocked, and the air inlet 112 can be connected to the notch 225 in a facing direction, and the negative pressure channel 122 can be connected to the second connecting channel 230 in a facing direction.

[0085] In some embodiments, see Figure 3 、 Figure 6 and Figure 8 The nozzle assembly 200 includes a nozzle 210 and a nozzle seal 220. The nozzle seal 220 is fixedly connected to the nozzle 210, and the suction port 211 is formed in the nozzle 210. The second connecting channel 230 includes a connecting hole 231, the aforementioned circumferential limiting groove 223 and a spacing channel 232, wherein the connecting hole 231 and the circumferential limiting groove 223 are both formed in the nozzle seal 220. The bottom end of the connecting hole 231 is used to communicate with the negative pressure channel 122, and the top end of the connecting hole 231 extends to the circumferential limiting groove 223. The spacing channel 232 is formed by the top outer wall of the nozzle seal 220 and the top inner wall of the nozzle 210. The circumferential limiting groove 223 is connected to the spacing channel 232. In addition, the connecting groove 221 is also connected to the suction port 211 through the above-mentioned spacing channel 232. The provision of the spacing channel 232 enables both the circumferential limiting groove 223 and the connecting groove 221 to be connected to the suction port 211 to achieve negative pressure detection.

[0086] In some embodiments, see Figure 9 and Figure 10 The bottom seal 140 also has a second through hole 144 and a third connecting channel 145. The bottom cover 150 has a third through hole 151. The top of the second through hole 144 is connected to the negative pressure channel 122. The third connecting channel 145 is formed on the side of the bottom seal 140 away from the negative pressure channel 122. The third connecting channel 145 is connected to the bottom end of the second through hole 144. The third through hole 151 is connected to the third connecting channel 145. The third through hole 151 is connected to the airflow sensor 330.

[0087] In some embodiments, see Figure 2 The battery assembly 300 is installed at one end of the atomizer assembly 100 away from the nozzle assembly 200, and the battery assembly 300 is used to power the atomizer assembly 100. The battery assembly 300 includes a power supply bracket 310, a battery 320, an airflow sensor 330, a sealing sleeve 340, a circuit board 350 and a first electrode 360. The battery 320, the airflow sensor 330, the sealing sleeve 340, the circuit board 350 and the first electrode 360 ​​are respectively installed on the power supply bracket 310. The battery 320, the airflow sensor 330 and the first electrode 360 ​​are respectively electrically connected to the circuit board 350. After the airflow sensor 330 detects negative pressure, it is fed back to the circuit board 350. The circuit board 350 is electrically connected to the second electrode 170 in the atomizer assembly 100 through the first electrode 360 ​​to power the atomizer assembly 100. The power supply bracket 310 has a fourth through hole connected to the third through hole 151, the sealing sleeve 340 is installed on the power supply bracket 310, the airflow sensor 330 is installed in the sealing sleeve 340, and the sealing sleeve 340 is connected to the fourth through hole, thereby realizing the communication between the airflow sensor 330 and the negative pressure channel 122.

[0088] In addition, a power supply housing 370 is also included, and the power supply housing 370 is sleeved on the outside of the power supply bracket 310 .

[0089] In this application, since the atomizing medium in the liquid storage chamber is consumable, it is necessary to inject new atomizing medium into the liquid storage chamber after the atomizing medium is consumed. In some embodiments, please refer to Figure 2 and Figure 10 The top of the liquid storage seat 120 is opened, and a liquid injection seal 160 is sealed and installed on the top of the liquid storage seat 120. The atomizer assembly 100 also includes a main shell 110, which is sleeved on the outside of the liquid storage seat 120 and the liquid injection seal 160. The main shell 110 and the liquid storage seat 120 are snap-fitted to axially abut the liquid injection seal 160 between the main shell 110 and the liquid storage seat 120 to achieve sealing.

[0090] In some embodiments, see Figure 10The liquid injection seal 160 includes a guide groove 161 and a liquid injection gap 162. The guide groove 161 is formed on the side of the liquid injection seal 160 away from the liquid storage chamber. The liquid injection gap 162 extends from the guide groove 161 to the liquid storage chamber. The liquid injection seal 160 having at least the guide groove 161 and the liquid injection gap 162 is radially interference fitted with the liquid storage seat 120.

[0091] It should be noted that the length of the liquid injection slit 162 is set to be greater than the outer diameter of the liquid injection tube, so that the liquid injection tube 500 can expand the liquid injection slit 162 and insert it into the liquid reservoir 120. In addition, because the portion of the liquid injection seal 160 having the liquid injection slit 162 is interference-fitted with the liquid reservoir 120, when the liquid injection tube 500 is removed, the opposing inner walls of the liquid injection slit 162 along the width direction can be tightly attached under the extrusion effect of the interference fit, thereby achieving a seal.

[0092] The length direction of the injection gap 162 is Figure 11 The X arrow in the figure points to the direction in which the size is relatively large; the width direction is Figure 11 The direction indicated by the Y arrow is the direction with relatively smaller size.

[0093] In some embodiments, see Figure 11 The guide groove 161 has relatively arranged guide surfaces 1611 on opposite sides along the width direction of the liquid injection gap 162. The two guide surfaces 1611 form an angle with each other, and the distance between the two guide surfaces 1611 gradually decreases toward the liquid injection gap 162 to guide the liquid injection tube 500 to be inserted into the liquid injection gap 162.

[0094] In some embodiments, see Figure 2 and Figure 11 The liquid injection seal 160 includes a contact portion 163 and a liquid injection portion 164, wherein the liquid injection portion 164 is inserted into the liquid storage seat 120, the contact portion 163 and the liquid injection portion 164 are integrally connected, the contact portion 163 longitudinally abuts between the liquid storage seat 120 and the main shell 110, and the guide groove 161 and the liquid injection gap 162 are both formed in the liquid injection portion 164.

[0095] Optionally, one set of guide grooves 161 and injection slits 162 may be provided, or multiple sets may be provided.

[0096] In some embodiments, see Figure 5 The air outlet pipe 111 is integrally formed on the main shell 110.

[0097] In one embodiment of the present application, see Figure 12The above-mentioned liquid storage chamber can also be open at the bottom, and the liquid injection seal 160 is installed at the bottom of the liquid storage seat 120. At this time, the liquid injection seal 160 and the bottom seal 140 can be shared, and the liquid injection gap 162 and the guide groove 161 are formed in the liquid injection seal 160.

[0098] In other embodiments of the present application, at least a portion of the nozzle assembly 200 can slide axially along the air outlet pipe 111 to switch the connection state between the air outlet 1111 and the external atmosphere. For example, when the nozzle assembly 200 is slid away from the atomizer assembly 100 as a whole, the air outlet 1111 is disconnected from the external atmosphere, and when the nozzle assembly 200 is slid toward the atomizer assembly 100 as a whole, the air outlet 1111 is connected to the external atmosphere; for example, when the nozzle seal 220 is slid away from the atomizer assembly 100 alone, the air outlet 1111 is disconnected from the external atmosphere, and when the nozzle seal 220 is slid toward the atomizer assembly 100 alone, the air outlet 1111 is connected to the external atmosphere.

[0099] In other embodiments of the present application, the nozzle seal 220 is movably connected to the air outlet pipe 111, and the nozzle 210 is movably connected to the nozzle seal 220. In other words, in this embodiment, the state of the air outlet 1111 can be switched only through the relative movement between the nozzle seal 220 and the air outlet pipe 111, without the need to move the entire nozzle assembly 200.

[0100] In other embodiments of the present application, the nozzle assembly 200 includes a nozzle 210 but does not include a nozzle seal 220 , and the opening and closing of the air inlet 112 , the air outlet 1111 and the negative pressure channel 122 are achieved through the relative movement of the nozzle 210 and the air outlet pipe 111 .

[0101] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
