The electronic atomization device is generally formed with an airflow channel. The airflow channel is configured to circulate an internal airflow inside the electronic atomization device. On one hand, the electronic atomization device can be started when a user vapes, and on the other hand, an aerosol formed by atomization in the electronic atomization device can be carried out. In addition, the circulation of the airflow can promote an atomization medium in the liquid storage cavity to flow, thereby implementing aeration. The airflow channel is generally provided with an air intake vent and an air exhaust vent. When the electronic atomization device is not used, the air intake vent and/or the air exhaust vent is generally covered to avoid misstart or to reduce liquid leakage. However, when both the air intake vent and the air exhaust vent are covered, the structure of the electronic atomization device is complex and the operation is troublesome. Moreover, when only the air intake vent or air exhaust vent is covered, the airflow channel is not completely isolated from the external airflow, and liquid leakage may occur.

To solve the foregoing problem, an embodiment of this application provides an electronic atomization device. By forming an air intake channel 150 and an atomization channel 160 in a housing assembly 100, communicating the air intake channel 150 and the atomization channel 160, and providing a movable member 200, the air intake channel 150 and the atomization channel 160 can be communicated with the external atmosphere, or both the air intake channel 150 and the atomization channel 160 can be disconnected from the external atmosphere only by driving the movable member 200 to move in the housing assembly 100. The electronic atomization device is not only simple in structure and easy in operation, but also capable of disconnecting both the air intake channel 150 and the atomization channel 160 from the external atmosphere, thereby reducing liquid leakage.

Referring to FIG. 1 to FIG. 3 and FIG. 5 together, the electronic atomization device provided in this embodiment of this application is described in detail. The electronic atomization device includes a housing assembly 100 and a movable member 200. The housing assembly 100 is formed with an air intake channel 150 and an atomization channel 160. The air intake channel 150 has a first end 151 and a second end 152. The atomization channel 160 has a third end 161 and a fourth end 162. The second end 152 of the air intake channel 150 is communicated with the fourth end 162 of the atomization channel 160. For example, the second end 152 of the air intake channel 150 is directly communicated with the fourth end 162 of the atomization channel 160, or the second end 152 of the air intake channel 150 is directly communicated with the fourth end 162 of the atomization channel 160 through another air guiding structure. The movable member 200 is movably disposed in the housing assembly 100. When the movable member is 200 in a first position, the first end 151 of the air intake channel 150 is communicated with the external atmosphere, and the third end 161 of the atomization channel 160 is communicated with the external atmosphere. When the movable member 200 is in a second position, the movable member 200 separately covers the first end 151 of the air intake channel 150 and the third end 161 of the atomization channel 160.

In the electronic atomization device provided by the embodiment of this application, by forming the air intake channel 150 and the atomization channel 160 in the housing assembly 100 and enabling the second end 152 of the air intake channel 150 to be communicated with the fourth end 162 of the atomization channel 160, that is, enabling the air intake channel 150 to be communicated with the atomization channel 160, when the movable member 200 is in the first position, the first end 151 of the air intake channel 150 is communicated with the external atmosphere, and the third end 161 of the atomization channel 160 is communicated with the external atmosphere. The external environment, the air intake channel 150, and the atomization channel 160 form an airflow loop. When the electronic atomization device is sucked at the third end 161 of the atomization channel 160, the external atmosphere enters the air intake channel 150 from the first end 151, enters the atomization channel 160 through the second end 152 and the fourth end 162, and finally carries an aerosol out of the atomization channel 160 through the third end 161. When the movable member 200 is in the second position, the movable member 200 separately covers the first end 151 of the air intake channel 150 and the third end 161 of the atomization channel 160, both the air intake channel 150 and the atomization channel 160 cannot be communicated with the external atmosphere, thereby reducing the aeration of the electronic atomization device when not in use. Not only e-liquid leakage is reduced, but also misstart is reduced. According to this application, separate communication between the air intake channel 150 and the external atmosphere and between the atomization channel 160 and the external atmosphere can be synchronously implemented through one movable member 200, the structure is simple, and the operation is easy. In addition, the air intake vent 121 and the air exhaust vent 122 are closed, to enable both the atomization channel 160 and the liquid storage cavity 190 to be in a sealed state, and liquid leakage due to the impact of the external air pressure does not occur. In addition, the air duct is closed to reduce odor overflow of the atomization medium in the liquid storage cavity 190. A fresh-keeping effect is achieved.

In an embodiment, referring to FIG. 2 and FIG. 5, the air intake channel 150 and the atomization channel 160 extend in the same direction. That is, the air intake channel 150 and the atomization channel 160 are arranged in parallel and spaced away. The first end 151 of the air intake channel 150 is arranged adjacent to the third end 161 of the atomization channel 160. Therefore, the movable member 200 can conveniently cover both the first end 151 of the air intake channel 150 and the third end 161 of the atomization channel 160. The second end 152 of the air intake channel 150 is disposed adjacent to the fourth end 162 of the atomization channel 160, to facilitate communication between the second end 152 of the air intake channel 150 and the fourth end 162 of the atomization channel 160. In addition, by enabling the air intake channel 150 and the atomization channel 160 to extend in the same direction, and to extend in the same as the length extension direction of the entire electronic atomization device, the airflow in the air intake channel 150 and the atomization channel 160 is enabled to be smooth and space occupied by the air intake channel 150 and the atomization channel 160 is enabled to be small. It may be understood that, in other embodiments of this application, the air intake channel 150 and the atomization channel 160 are not necessarily disposed in parallel, and the air intake channel 150 and/or the atomization channel 160 may extend in a curved manner, as long as the two channels are communicated, and the movable member 200 can simultaneously open or close openings of the two channels.

In an embodiment, referring to FIG. 3 and FIG. 5, the movable member 200 is slidably disposed in the housing assembly 100. When in use, the air intake channel 150 and the atomization channel 160 are enabled to be communicated with the external atmosphere only by sliding the movable member 200 to the first position, and then suction is performed. When not in use, both the first end 151 of the air intake channel 150 and the third end 161 of the atomization channel 160 are covered only by sliding the movable member 200 to the second position, to reduce occurrence of airflow circulation in the atomization channel 160. The operation is easy and the movable space of the movable member 200 is not large. It may be understood that, in other embodiments of this application, the movable member 200 may alternatively be rotatably disposed in the housing assembly 100 when the space inside the housing assembly 100 is large enough, and the movable member 200 is switched between the first position and the second position by rotating the movable member 200, which is not uniquely limited herein.

In an embodiment, referring to FIG. 3 and FIG. 5, the housing assembly 100 is formed with an air intake vent 121, an air exhaust vent 122, and a mounting cavity 170. The air intake vent 121 and the air exhaust vent 122 are separately communicated with the mounting cavity 170. The movable member 200 is movably disposed in the mounting cavity 170. When the movable member 200 is in the first position, the air intake vent 121 is communicated with the air intake channel 150 and the air exhaust vent 122 is communicated with the atomization channel 160. When the movable member 200 is in the second position, the air intake vent 121 is discommunicated from the air intake channel 150 and the air exhaust vent 122 is discommunicated from the atomization channel 160. Through the arrangement of the air intake vent 121, the air exhaust vent 122, and the mounting cavity 170, the movable member 200 can be accommodated in the mounting cavity 170, and in addition, an air exhaust vent 122 may be formed on the surface of the housing assembly 100 and a suction part for suction by a user may be formed at the air exhaust vent 122. It may be understood that, in other embodiments of this application, both the air intake vent 121 and the air exhaust vent 122 may alternatively be formed on the movable member 200, and in addition, the movable member 200 is slidably disposed on the surface of the housing assembly 100, and a suction part for a user to suck is formed on the movable member 200, which is not uniquely limited herein.

In an embodiment, referring to FIG. 1, FIG. 2, and FIG. 5, the housing assembly 100 includes a main housing 110 and a suction mouthpiece 120. The air intake channel 150 and the atomization channel 160 are formed, in a spaced away manner, in the main housing 110. The suction mouthpiece 120 is connected to the main housing 110. The suction mouthpiece 120 and the main housing 110 are enclosed to form the foregoing mounting cavity 170. The air intake vent 121 and the air exhaust vent 122 are separately formed on the suction mouthpiece 120. The movable member 200 is slidably disposed in the mounting cavity 170.

In addition, to facilitate suction by a user, the suction mouthpiece 120 is further formed with a round flat suction part at a position corresponding to the air exhaust vent 122.

In an embodiment, referring to FIG. 5, FIG. 7, and FIG. 8, the housing assembly 100 is formed with a drainage channel 123 for introducing the external atmosphere through the air intake vent 121 into the side of the movable member 200 facing towards the air intake vent 121. The side of the movable member 200 away from the air intake vent 121 is provided with a connection slot 210. When the movable member 200 is in the first position, the connection slot 210 is communicated between the drainage channel 123 and the air intake channel 150.

Specifically, the air intake vent 121 is formed on the side of the movable member 200 away from the air intake channel 150. With the arrangement of the drainage channel 123, the airflow entering, from the air intake vent 121, the side of the movable member 200 away from the air intake channel 150 can be directed to the side of the movable member 200 facing towards the air intake channel 150. That is, the airflow is enabled to bypass the movable member 200, and then the airflow is introduced into the air intake channel 150 through the connection slot 210. Therefore, the flow path of the airflow is increased, and the airflow is prevented from directly passing through the movable member 200 to enter the air intake channel 150, thereby reducing the airflow noise and improving the user experience. It may be understood that, in other embodiments, two through slots can alternatively be formed directly on the movable member 200. When the movable member 200 is in the first position, one of the through slots is connected between the air intake channel 150 and the air intake vent 121, and the other through slot is connected between the atomization channel 160 and the air exhaust vent 122. When the movable member 200 is in the second position, the two through slots are provided, to receive the air intake channel 150 and the atomization channel 160, respectively.

In an embodiment, referring to FIG. 7, the drainage channel 123 is mainly formed on the suction mouthpiece 120, and the structure of the suction mouthpiece 120 is designed, so that the airflow can bypass the movable member 200. It should be understood that, in other embodiments of this application, the drainage channel 123 may alternatively be formed on the movable member 200 or the main housing 110. This is not limited herein.

In an embodiment, referring to FIG. 5, the movable member 200 is spaced apart from the bottom portion of the mounting cavity 170, to form an airflow gap 1000. The airflow gap 1000 is configured to be communicated with the drainage channel 123, so that the airflow in the drainage channel 123 can flow to the connection slot 210.

Specifically, referring to FIG. 5, when the movable member 200 is in the first position, the connection slot 210 is disposed across the outer edge of the air intake channel 150. That is, a portion of the connection slot 210 is disposed facing right towards the air intake channel 150, so as to be communicated with the air intake channel 150, and the other portion of the connection slot 210 is disposed facing right towards the airflow gap 1000, so as to be communicated with the drainage channel 123 through the airflow gap 1000.

In an embodiment, referring to FIG. 7, two opposite sides of the housing assembly 100 are respectively provided with drainage channels 123 along the movable member 200, and the drainage channels 123 on the two sides respectively introduce external airflows to the side of the movable member 200 facing towards the air intake channel 150 from the two opposite sides of the movable member 200, and respectively guide the airflows to the air intake channel 150 through the connection slots 210.

Specifically, referring to FIG. 5 and FIG. 7, the movable member 200 is slidably disposed on the housing assembly 100 along a first direction X, two opposite sides of the movable member 200 along a second direction Y are provided with drainage channels 123, the first direction X and the second direction Y are perpendicular to each other, and the first direction X and the second direction Y are perpendicular to an extending direction of the atomization channel 160.

In an embodiment, referring to FIG. 7, two sides of the movable member 200 along the second direction Y are respectively provided with two or more drainage channels 123, the drainage channels 123 on the same side of the movable member 200 are spaced apart along the first direction X, and the drainage channels 123 respectively introduce an external airflow into the airflow gap 1000.

In an embodiment, referring to FIG. 8, the connection slot 210 includes two first connection parts 211 and a second connection part 212, the two first connection parts 211 are spaced apart along the second direction Y, the two first connection parts 211 are separately communicated with the second connection part 212, the two first connection parts 211 are respectively configured to receive the airflows introduced into the drainage channels 123 on the two sides of the movable member 200, and the second connection part 212 is communicated with the air intake channel 150.

In an embodiment, referring to FIG. 6, the housing assembly 100 is further formed with a start air duct 111, one end of the start air duct 111 is communicated with the air exhaust vent 122, and the other end of the air intake channel 150 is communicated with a microphone assembly 700.

The start air duct 111 is communicated with the air exhaust vent 122, so that when a user sucks the air exhaust vent 122, a negative pressure is formed at the air exhaust vent 122, and the negative pressure is transmitted to the microphone assembly 700 to be sensed by the microphone assembly 700, thereby starting the electronic atomization device. In addition, by configuring the separate start air duct 111, compared with directly starting through the atomization channel 160, the electronic atomization device can be started by sucking the air exhaust vent 122, even if the atomization medium in the atomization channel 160 and the liquid storage cavity 190 has a poor fluidity due to a high viscosity, so that after a communication position between the atomization channel 160 and the liquid storage cavity 190 is heated for a period of time, the fluidity of the atomization medium becomes better and the atomization medium is then atomized to form an aerosol.

In an embodiment, the start air duct 111 is formed in the main housing 110, and the start air duct 111, the air intake channel 150, and the atomization channel 160 are arranged spaced away from each other.

In an embodiment, referring to FIG. 3, the movable member 200 and the housing assembly 100 jointly partition the mounting cavity 170 into a first cavity part 171 and a second cavity part 172. The first cavity part 171 is communicated with the air intake vent 121, and the second cavity part 172 is communicated with the air exhaust vent 122. When the movable member 200 is in the first position, the first cavity part 171 is communicated with the air intake channel 150, and the second cavity part 172 is communicated with the atomization channel 160. By isolating the first cavity part 171 from the second cavity part 172, the airflow from the air intake vent 121 is prevented from directly entering the atomization channel 160, and the airflow exported from the atomization channel 160 is further prevented from entering the air intake channel 150.

In an embodiment, the start air duct 111 is communicated with the second cavity part 172, so that the air intake channel 150 is isolated from the start air duct 111, and therefore the air exhaust vent 122 and the start air duct 111 can still generate a negative pressure by sucking the air exhaust vent 122 even if the atomization medium in the position of the atomization channel 160 having the atomization core 800 cannot form an airflow to flow due to that the atomization medium therein is thick. Therefore, the atomization core 800 is started to heat the atomization medium, and after the fluidity of the atomization medium becomes better, the atomization medium forms a stable airflow, so that atomization is implemented.

In an embodiment, referring to FIG. 3 and FIG. 7, the housing assembly 100 is formed with a first partition plate 124, and the movable member 200 is formed with a recess 220. When the movable member 200 is in the first position, the first partition plate 124 partitions the mounting cavity 170 into a first cavity part 171 and a second cavity part 172. When the movable member 200 is in the second position, the recess 220 communicates the first cavity part 171 and the second cavity part 172 on two sides of the first partition plate 124, so as to communicate the air intake vent 121 and the air exhaust vent 122. With such the arrangement, when the movable member 200 covers both the air intake channel 150 and the atomization channel 160 and a negative pressure is formed at the air exhaust vent 122 when being sucked, due to the fact that the first cavity part 171 is communicated with the second cavity part 172, the start air duct 111 can be communicated with the external atmosphere through the air intake vent 121, and false starting does not occur even if the negative pressure is formed at the air exhaust vent 122. In other embodiments of this application, alternatively, the movable member 200 is directly attached to an inner wall of the housing assembly 100, so that the air intake vent 121 and the air exhaust vent 122 can be isolated without providing a partition plate.

In an embodiment, referring to FIG. 2 and FIG. 5, the electronic atomization device further includes a seal member 300. The seal member 300 is covered on the end surfaces of the first end 151 and the third end 161, and the seal member 300 is formed with a first connection hole 310 communicated with the air intake channel 150 and a second connection hole 320 communicated with the atomization channel 160. The movable member 200 is slidably disposed on the seal member 300. Through the configuration of the seal member 300, the scaling performance of the air intake channel 150 and the atomization channel 160 in the closed state can be improved.

In an embodiment, referring to FIG. 2 and FIG. 5, a liquid storage cavity 190 is further formed in the main housing 110, the liquid storage cavity 190 and the atomization channel 160 are spaced apart, a connection port is formed between the liquid storage cavity 190 and the atomization channel 160, the atomization core 800 is installed in the atomization channel 160 and blocked at the connection port, the atomization medium in the liquid storage cavity 190 enters the atomization core 800 through the connection port, so as to be heated by the atomization core 800 to form an aerosol, and the aerosol is carried by the airflow from the air intake channel 150 to the atomization channel 160, to the air exhaust vent 122 and vaped by a user.

Specifically, the main housing 110 is formed with an accommodating cavity, an atomization pipe 140 is installed in the accommodating cavity, the atomization channel 160 is formed in the atomization pipe 140, and the liquid storage cavity 190 is formed in a position outside the atomization pipe 140 in the accommodating cavity. In an embodiment, referring to FIG. 3 and FIG. 5, the seal member 300 is accommodated in the mounting cavity 170, the outer peripheral wall of the seal member 300 is in interference abutment with the inner peripheral wall of the suction mouthpiece 120, the seal member 300 is abutted against the side of the main housing 110 facing towards the suction mouthpiece 120, and the seal member 300 is covered on the end surface of the air intake channel 150, the end surface of the atomization channel 160, and the end surface of the liquid storage cavity 190. The first end 151 of the air intake channel 150, the third end 161 of the atomization channel 160, and the outer end of the liquid storage cavity 190 are all sealed through the seal member 300, thereby reducing liquid leakage.

In an embodiment, referring to FIG. 5, the movable member 200 is slidably disposed on the seal member 300, a first projecting ring 330 extends towards the movable member 200 from the seal member 300 in a position corresponding to an end port of the first end 151, and a second projecting ring 340 extends towards the movable member 200 from the seal member 300 in a position corresponding to an end port of the third end 161, and the movable member 200 is slidably supported on the first projecting ring 330 and the second projecting ring 340. Through the configuration of the first projecting ring 330 and the second projecting ring 340, the movable member 200 can be supported at a particular height, for an airflow gap 1000 to be formed between the movable member 200 and the seal member 300, so that the drainage channel 123 introduces the external airflow to the airflow gap 1000. In addition, through the configurations of the first projecting ring 330 and the second projecting ring 340, the sliding resistance of the movable member 200 on the seal member 300 can further be reduced, due to the fact that the seal member 300 is an elastic member and is easily deformed, which may hinder sliding of the movable member 200.

In an embodiment, referring to FIG. 4, an annular slot 311 is formed on the inner side wall of the first connection hole 310. Specifically, the annular slot 311 is recessed from the inner side wall between two axial ends of the first connection hole 310. Through the configuration of the annular slot 311, the structural material of the seal member 300 corresponding to the first connection hole 310 can be reduced. That is, the elastic deformation capability of the seal member 300 corresponding to the first connection hole 310 can be improved, so that when the movable member 200 slides on the first projecting ring 330, the sealing performance of the seal member 300 and the movable member 200 can be ensured, and further the sealing performance of the air intake channel 150 and the atomization channel 160 can be ensured. If a direct pressure deformation occurs, the amount of deformation has a large impact on the elastic force, and the requirements on the dimension and assembling size of the seal member 300 are quite high, which is not conducive to the sliding stability of the movable member 200. It may be understood that, in other embodiments, an annular slot 311 may alternatively be formed on the inner side wall of the second connection hole 320, or the annular slot 311 may be formed on the inner side walls of both the first connection hole 310 and the second connection hole 320. This is not limited herein.

In an embodiment, referring to FIG. 3 and FIG. 5, the side of the seal member 300 facing towards the movable member 200 is provided with a pressing block 400, and the pressing block 400 is abutted between the seal member 300 and the housing assembly 100. Specifically, due to the fact that the seal member 300 has an elasticity, the seal member 300 can not only deform in the direction towards the liquid storage cavity 190, so as to form a seal of the liquid storage cavity 190, but also deform in the direction towards the movable member 200. If the seal member 300 deforms in the direction towards the movable member 200, the sliding resistance of the movable member 200 can be increased. However, for the configuration of the pressing block 400 in this embodiment, due to the fact that the function of the pressing block 400 is to press the seal member 300, while the sealing performance is strengthened, the seal member 300 can be effectively prevented from deforming in the direction towards the movable member 200, and the sliding resistance to the movable member 200 is reduced.

In an embodiment, referring to FIG. 5, the pressing block 400 is pressed on the seal member 300, and the pressing block 400 is disposed to receive the first projecting ring 330 and the second projecting ring 340. An edge of the pressing block 400 is abutted between the seal member 300 and the housing assembly 100, so as to position the pressing block 400. In addition, to prevent the configuration of the pressing block 400 from affecting the configuration of the airflow gap 1000, the pressing block 400 is mainly disposed at a position of the seal member 300 corresponding to the liquid storage cavity 190 and the atomization channel 160.

In an embodiment, referring to FIG. 5, a reserved gap is provided between the pressing block 400 and the movable member 200, and the purpose of providing the reserved gap is to prevent a condensate from sticking the movable member 200 and the pressing block 400 together, which has a relatively large impact on the sliding resistance of the movable member 200.

Specifically, the height of the pressing block 400 is lower than the height of the first projecting ring 330 and the second projecting ring 340. That is, when the pressing block 400 is attached to the seal member 300 and the movable member 200 is slidably disposed on the first projecting ring 330, there is a distance between the movable member 200 and the pressing block 400.

In an embodiment, referring to FIG. 3, FIG. 5, FIG. 7, and FIG. 9, at least one positioning column 126 is formed on the suction mouthpiece 120, at least one positioning slot 370 is formed on the seal member 300, and the positioning column 126 is in interference insertion fit with the positioning slot 370. In this embodiment, not only an interference fit is formed between the outer peripheral wall of the seal member 300 and the inner peripheral wall of the suction mouthpiece 120, but also the interference insertion fit is formed between the positioning column 126 and the positioning slot 370. Through the above configuration, the sealing connection between the seal member 300 and the housing assembly 100 can be more reliable, so that the structure and shape of the seal member 300 are stable, and further the installation stability of the pressing block 400 and the movable member 200 on the seal member 300 is ensured.

In an embodiment, referring to FIG. 9 and FIG. 10, a second partition plate 350 is formed on the seal member 300, the movable member 200 is slidably abutted between the first partition plate 124 and the second partition plate 350, and the first partition plate 124, the second partition plate 350, and the movable member 200 jointly partition the mounting cavity 170 into a first cavity part 171 and a second cavity part 172.

Specifically, referring to FIG. 9 and FIG. 10, two second partition plates 350 are formed on two opposite sides of the first projecting ring 330. The two second partition plates 350 are spaced apart along the second direction Y. A connection rib 360 is formed between the two second partition plates 350 and the first projecting ring 330. The connection rib 360 and the first projecting ring 330 have the same height. The movable member 200 can be slidably arranged on the first projecting ring 330 and the connection rib 360. The height of the two second partition plates 350 is greater than that of the connection rib 360. The two second partition plates 350 are configured to be connected to two opposite sides of the movable member 200 along the second direction Y, so as to isolate the mounting cavity 170 along the first direction X. In addition, referring to FIG. 7 and FIG. 10, the side of the movable member 200 away from the seal member 300 is abutted against the first partition plate 124. The first partition plate 124 extends along the second direction Y. The first partition plate 124 is configured to partition a portion of the mounting cavity 170 located above the movable member 200 along the first direction X.

In addition, a plurality of support ribs 125 are further formed on the suction mouthpiece 120. The support ribs 125 are connected to the first partition plate 124. The height of the support ribs 125 is the same as that of the first partition plate 124. The support ribs 125 and the first partition plate 124 jointly slidably support and limit the side of the movable member 200 away from the seal member 300.

In an embodiment, referring to FIG. 2, FIG. 5, and FIG. 6, the housing assembly 100 is further formed with an electrical cavity 180. A battery 500 and a circuit assembly 600 are disposed in the electrical cavity 180. The electrical cavity 180, the air intake channel 150, and the atomization channel 160 are arranged spaced away from each other. In this embodiment, the electrical cavity 180 in which the battery 500 and the circuit assembly 600 are installed is spaced apart from the air intake channel 150 and the atomization channel 160, separately. That is, the airflow during atomization of the electronic atomization device does not pass through the battery 500 and the circuit assembly 600, so as to prevent a toxic substance in the battery 500 and the circuit assembly 600 from being carried to a user's mouth, thereby improving the use safety of the electronic atomization device.

In an embodiment, referring to FIG. 5, the housing assembly 100 is further formed with a connection cavity 112. The second end 152 of the air intake channel 150 and the fourth end 162 of the atomization channel 160 are separately communicated with the connection cavity 112. Through the configuration of the connection cavity 112, the air intake channel 150 can be communicated with the atomization channel 160, and in addition the airflow in the air intake channel 150 and the atomization channel 160 can be prevented from flowing through the electrical cavity 180.

In an embodiment, the connection cavity 112 is disposed on the side of the atomization channel 160 away from the movable member 200. The connection cavity 112 is disposed on the side of the air intake channel 150 away from the movable member 200. Projections of both the air intake channel 150 and the atomization channel 160 in the connection cavity 112 are within a range of the connection cavity 112.

In an embodiment, referring to FIG. 5, the housing assembly 100 is further formed with an electrical cavity 180 and a connection cavity 112 connected between the electrical cavity 180 and the atomization channel 160. An atomization core 800 is installed in the atomization channel 160. A circuit assembly 600 is installed in the electrical cavity 180. A mounting seat 900 is installed in the connection cavity 112. The mounting seat 900 is formed with a mounting hole 910 through which the heating wire passes. Two opposite ends of the heating wire are respectively connected to the atomization core 800 and the circuit assembly 600. The heating wire is sealed on the mounting seat 900 through sealing glue. Through the configuration of the connection cavity 112, on one hand, the connection cavity 112 is configured to connect the air intake channel 150 and the atomization channel 160, and on the other hand, the connection cavity 112 is configured to implement an electrical connection between the circuit assembly 600 and the atomization core 800. Through the configuration of the mounting seat 900, on one hand, the mounting seat 900 is configured to guide installation of the heating wire, and on the other hand, the mounting seat 900 is configured to seal the mounting hole 910 by the sealing glue, so as to prevent the atomization channel 160 from being communicated with the electrical cavity 180.

In an embodiment, referring to FIG. 4, a cross-sectional area of the mounting hole 910 gradually decreases from the end approaching the atomization core 800 to the end away from the atomization core 800, so that the mounting hole 910 has a guiding effect on the heating wire. When the atomization core 800 has been assembled in the atomization channel 160 and two heating wires are generally connected to the atomization core 800 for delivery, to avoid that the two heating wires cannot be accurately inserted into the two mounting holes 910 when the mounting seat 900 is installed in the connection cavity 112, the cross-sectional areas of the sides of the mounting holes 910 facing towards the atomization core 800 are set to be relative large in this application, so that the heating wires can be quickly inserted into the mounting holes 910, and plus the guide function of the variable cross-sectional areas of the mounting holes 910 for the heating wires, the heating wires can accurately extend from the mounting holes 910 to be connected to the circuit assembly 600.

Specifically, a longitudinal cross-section of the inner side surface of the mounting hole 910 may be a straight line extending obliquely from one end approaching the atomization core 800 to one end away from the atomization core 800 relative to the central axis thereof, or may be an arc or a curve.

In an embodiment, the two mounting holes 910 are symmetrically provided, and the longitudinal cross-sections of the mounting holes 910 are asymmetrical. That is, the cross-sections of the mounting holes 910 are not circular.

Specifically, the accommodation tank 920 is formed on the side of the mounting seat 900 facing towards the atomization channel 160, and the accommodation tank 920 is communicated with the atomization channel 160 and the air intake channel 150, separately. Through the configuration of the accommodation tank 920, when there is condensate or leaked e-liquid flows downwards in the atomization channel 160, the condensate and leaked e-liquid can be stored through the accommodation tank 920. In addition, the condensate and leaked e-liquid can be prevented from obstructing the communication between the air intake channel 150 and the atomization channel 160.

In an embodiment, referring to FIG. 4 and FIG. 11, the mounting seat 900 is a seal member 300.

The side of the mounting seat 900 facing towards the electrical cavity 180 is formed with a second projecting rib 940 surrounding the peripheries of the mounting holes 910. Through the configuration of the first projecting rib 930, the air intake channel 150 and the atomization channel 160 are enabled to be communicated on the inner side of the first projecting rib 930, and the air intake channel 150 and the atomization channel 160 can be isolated from the electrical cavity 180, so as to prevent the airflow from entering the electrical cavity 180. In addition, through the configuration of the second projecting rib 940, the connection cavity 112 and the electrical cavity 180 can be sealed and isolated by the second projecting rib 940 even if the scaling function of the first projecting rib 930 fails, so that a double-layer sealing guarantee can be formed and the sealing performance can be provided.

Besides, referring to FIG. 6, to facilitate the installation of the mounting seat 900, an opening is formed on one side of the connection cavity 112, and a third projecting rib 950 is further formed on the surface of the mounting seat 900.
