BACKGROUND

Currently, in the electronic atomization industry, electronic atomization devices are mainly aerosol generation devices suitable for solid aerosolisable mediums. Compared with cigarettes that burn tobacco, the electronic atomization device has an advantage that it adopts evaporation process or baking process to replace the burning process, and the generation of irritating toxic and carcinogenic substances is avoided, the taste is better, and the electronic atomization device can be suitable for various types of solid aerosolisable medium.

Currently, the commercial electronic atomization device usually includes the following components: a box accommodating solid aerosolisable mediums, an atomization assembly, and a battery. In the conventional structure, the atomization assembly is provided on an upper portion of the battery, i.e., the atomization assembly is provided between a mouthpiece and the battery, while a heating component is located inside the atomization assembly. The solid aerosolisable medium with high consistency is stored in the box. Before the electronic atomization device leaves a factory, the solid aerosolisable medium needed to be put into the box, then the box containing the solid aerosolisable medium is put into a heating cavity of the atomization assembly, and finally the atomization assembly and the battery are connected with a seal.

In the present disclosure, an aerosolizable medium refers to a substance that can be heated to provide an aerosol. The aerosolizable medium includes tobacco material, a composition containing tobacco ingredients or nicotine or flavoring ingredients, such as a liquid composition, a solid composition or a solid-liquid mixture.

Referring to FIGS. 1 to 4, an embodiment of the present disclosure provides an electronic atomization device 10. The electronic atomization device 10 is configured to heat an aerosolisable medium inside the electronic atomization device 10 to form an aerosol for a user to inhale. The following description will be made by taking the electronic atomization device 10 for heating a solid aerosolisable medium to generate an aerosol as an example.

The electronic atomization device 10 according to an embodiment of the present disclosure includes a housing 100, an atomization assembly 200, and a power supply assembly 300.

In one embodiment, referring to FIG. 3 and FIG. 4, the housing 100 is provided with an accommodation cavity 103 configured to accommodate the power supply assembly 300, and the housing 100 is provided with a mounting groove 104 extending through two opposite sides of the housing 100. The mounting groove 104 and the accommodation cavity 103 are isolated from each other. One end of the housing 100 is provided with an air outlet hole 101, and the mounting groove 104 is provided at one end of the housing 100 away from the air outlet hole 101. A groove wall of the mounting groove 104 is provided with an air passing hole 102 in communication with the air outlet hole 101. The atomization assembly 200 is detachably inserted into the mounting groove 104. The atomization assembly 200 has an atomization cavity 203 and includes an atomization core 230 provided in the atomization cavity 203. The atomization core 230 is electrically connected to the power supply assembly 300. The atomization assembly 200 is further provided with an air inlet hole 201 and an air vent hole 202. The air inlet hole 201, the atomization cavity 203, the air vent hole 202, the air passing hole 102, and the air outlet hole 101 are in communication with each other sequentially. The power supply assembly 300 is configured to supply power to the atomization assembly 200. When the power supply assembly 300 supplies power to the atomization assembly 200, the atomization core 230 can heat the aerosolisable medium accommodated in the atomization cavity 203 to generate the aerosol, and then the aerosol is discharged through the air vent hole 202, the air passing hole 102, and the air outlet hole 101 sequentially for a user to inhale.

The atomization assembly 200 is detachably inserted into the mounting groove 104. In this embodiment, the atomization assembly 200 is detachably inserted into the mounting groove 104 through a snap-groove connection. In one embodiment, as shown in FIG. 3, one of an outer wall of the atomization assembly 200 and the groove wall of the mounting groove 104 is provided with a buckle 106, and the other one of the outer wall of the atomization assembly 200 and the groove wall of the mounting groove 104 is provided with a locking groove 204 corresponding to the buckle 106. The buckle 106 can be snapped into the locking groove 204, and the atomization assembly 200 can be detachably inserted into the mounting groove 104. In other embodiments, the atomization assembly 200 may be detachably inserted into the mounting groove 104 by magnetic attraction structures.

Compared with the fixing manner of magnetic attraction, the present embodiment can avoid that the atomization assembly 200 is difficult to disassemble due to too strong magnetism, can also avoid that the atomization assembly 200 is easy to fall off from the mounting groove 104 due to insufficient magnetism, and can avoid the problems such as an increased cost and an increased device volume caused by the arrangement of the magnetic attraction structure.

As such, when the aerosolisable medium in the atomization assembly 200 is exhausted or the atomization assembly 200 malfunctions, the user can easily replace the atomization assembly 200, and the user can be convenient to use, the risk of scrapping the whole machine due to local damage of the electronic components can be reduced, the service life of the product is prolonged, and the environmental pollution and the resource waste can be reduced. Further, since the mounting groove 104 extends through the opposite sides of the housing 100, when removing the atomization assembly 200, the user only needs to push the atomization assembly 200 with his fingers to move the atomization assembly 200 along an axial direction of the mounting grooves 104, which facilitates the user's operation and greatly improves the user's experience.

The mounting groove 104 has a limiting end 104a and a mounting end 104b that are opposite in an axial direction thereof. Further, in order to prevent the user from inserting the atomization assembly 200 into the mounting groove 104 in a wrong direction, that is, in order to ensure that the atomization assembly 200 can only be inserted into the mounting groove 104 from the mounting end 104b rather than the limiting end 104a, in this embodiment, an inner diameter of the mounting end 104b is greater than an inner diameter of the limiting end 104a, and the atomization assembly 200 can merely be inserted into the mounting groove 104 from the mounting end 104b, to prevent the atomization assembly 200 from being inserted into the mounting groove 104 in the wrong direction during mounting.

In another embodiment, an edge of the opening of the limiting end 104a may be provided with a limiting structure extending into the mounting groove 104, such as a protrusion or a rib extending from the edge of the opening of the limiting end 104a to a center of the mounting groove 104. In one embodiment, an inner peripheral surface of the mounting groove 104 may be configured to extend obliquely along the axial direction of the mounting groove 104. Such arrangements can also enable the inner diameter of the opening of the mounting end 104b to be greater than the inner diameter of the opening of the limiting end 104a, which is not limited herein.

In this embodiment, in order to avoid misalignment of the atomization assembly 200 due to mutual rotation when the atomization assembly 200 is inserted into the mounting groove 104, referring to FIG. 3, an outer peripheral surface of a portion of the atomization assembly 200 inserted into the mounting groove 104 includes a first anti-rotation surface 205 that is flat, and outer peripheral surfaces of other portions of the atomization assembly 200 are arc surfaces. The air vent hole 202 is formed on the first anti-rotation surface 205. Correspondingly, a portion of the groove wall of the mounting groove 104 includes a second anti-rotation surface 104a corresponding to the first anti-rotation surface 205 and being flat, and the other portions of the groove wall of the mounting groove 104 are also arc surfaces. The air passing hole 102 is formed on the second anti-rotation surface 104a. A contour of the groove wall of the mounting groove 104 is adapted to a contour of the outer peripheral surface of the portion of the atomization assembly 200 inserted into the mounting groove 104, and when the atomization assembly 200 is inserted into the mounting groove 104, the first anti-rotation surface 205 is in contact with the second anti-rotation surface 104a, and the atomization assembly 200 has only one mounting direction in the circumferential direction thereof. Therefore, when the atomization assembly 200 is inserted into the mounting groove 104, the misalignment due to mutual rotation can be prevented.

It should be understood that the contour of the groove wall of the mounting groove 104 and the contour of the outer peripheral surface of the portion of the atomization assembly 200 inserted into the mounting groove 104 are not limited to the shapes shown in the embodiment, as long as there is an anti-rotation surface, and the atomization assembly 200 cannot rotate after being inserted into the mounting groove 104.

Referring to FIG. 4 and FIG. 5, in one embodiment, a top end of the housing 100 is provided with a mouthpiece 105, and the air outlet hole 101 extends through two opposite ends of the mouthpiece 105. The air outlet hole 101 and the air passing hole 102 are coaxially spaced arranged. The electronic atomization device 10 further includes an air vent pipe 400 provided in the accommodation cavity 103. The air vent pipe 400 is provided with a main air channel 401 extending through two opposite ends of the air vent pipe 400, and the air passing hole 102 and the air outlet hole 101 are in communication with each other through the main air channel 401. The atomization assembly 200 further includes a first sealing member 500 and a second sealing member 600. The first sealing member 500 is made of silica gel and is provided in the accommodation cavity 103 adjacent to the air outlet hole 101. The second sealing member 600 is made of silica gel and is provided in the accommodation cavity 103 adjacent to the air outlet hole 102. The first sealing member 500 is opposite to and spaced from the second sealing member 600. The mouthpiece 105 is inserted into a side of the first sealing member 500, one end of the air vent pipe 400 is inserted into a side of the first sealing member 500 away from the mouthpiece 105, and the other end of the air vent pipe 400 is inserted into the second sealing member 600. The first sealing member 500 is configured to prevent condensate generated by the aerosol from flowing back into the housing 100 from the mouthpiece 105 and causing a short circuit of the power supply assembly 300. The second sealing member 600 is configured to prevent the condensate in the air vent pipe 400 from flowing back into the atomization assembly 200.

In this way, by providing the straight-through air vent pipe 400 with no other components in the air vent pipe 400, compared with the conventional electronic atomization device in which an atomization core in is usually provided in air vent pipe, the above-mentioned structure makes it easier for the user to clean the condensed substances or other impurities remaining in the main air channel 401. The user only needs to use a straight brush adapted to the mouthpiece 105 to insert the main air channel 401 from the air outlet hole 101 at the mouthpiece 105, and then the straight brush can directly extend through the whole main air channel 401, and all impurities in the main air channel 401 can be cleaned out from the air outlet hole 102 without any residual impurities. The cleaning effect is very good, and there is no need to disassemble individual parts for cleaning, and the cleaning operation is very convenient.

In one embodiment, an outer diameter of the air vent pipe 400 is 0.5 cm to 1 cm. Such an arrangement can be more convenient for arranging various components in the housing 100, to save space, and is also convenient for selecting suitable cleaning tools to extend into the main air channel 401 to clean the air vent pipe 400.

It should be noted that since the air vent pipe 400 is a standard member with a constant length. Depths of both ends of the air vent pipe 400 inserted into the first sealing member 500 and the second sealing member 600 should be limited, to prevent the other end of the air vent pipe 400 from falling off from the first sealing member 500 or the second sealing member 600 due to too deep insertion of one end of the air vent pipe 400. Therefore, referring to FIG. 9, in one embodiment, an outer peripheral surface of the air vent pipe 400 is further provided with a limiting member 700. One side of the limiting member 700 abuts against the second sealing member 600, and an inner peripheral surface of the limiting member 700 and the outer peripheral surface of the air vent pipe 400 have steps, and the limiting member 700 can limit the insertion depth of the air vent pipe 400 into the second sealing member 600.

It should be understood that the limiting member 700 may be integrally connected with the air vent pipe 400, or may be fixedly connected to the air vent pipe 400, which is not limited herein.

Referring to FIG. 4 and FIG. 5, in the illustrated embodiment, the power supply assembly 300 includes a battery 310 and a circuit board 320. The battery 310 is provided on one side of the circuit board 320 and electrically connected to the circuit board 320. The circuit board 320 is sleeved on and snapped to the outer wall of the mounting groove 104, to be fixed in the accommodation cavity 103 of the housing 100. The circuit board 320 is provided with at least two electrodes 321. Referring to FIG. 6, the atomization assembly 200 correspondingly has at least two electrode contacts 206. Each electrode 321 is electrically connected to a corresponding electrode contact 206.

In this embodiment, three electrodes 321 are provided, and three electrode contacts 206 are correspondingly provided. Each electrode 321 abuts against one corresponding electrode contact 206, to achieve the electrical connection between the power supply assembly 300 and the atomization assembly 200. It should be noted that, among the three electrodes 321, one electrode 321 is a positive electrode, another electrode 321 is a negative electrode, and the remaining one electrode 321 can be configured to reading, writing, collecting, interacting, etc. of information between the atomization assembly 200 and the power supply assembly 300, to read information in a chip, a circuit, or a sampling resistor in the atomization assembly 200, and the circuit board 320 in the power supply assembly 300 can control and match different heating modes according to different atomization assemblies 200.

It should be noted that the power supply assembly 300 may be omitted, in which case the atomization assembly 200 may be powered by an external power supply, which is not limited herein.

Referring to FIGS. 4 and 7, the atomization assembly 200 includes a main body 210 and a heating pot 220. The atomization cavity 203 is formed in the main body 210, and the heating pot 220 is provided in the atomization cavity 203 coaxially with the main body 210 and is provided coaxially with the mounting groove 104.

The diameter of the first pot body 221 is less than the diameter of the second pot body 222. The first cavity 221a is formed in the first pot body 221, and the second cavity 222a is formed in the second pot body 222. When the atomization core 230 is powered on to generate heat, the aerosolisable medium (e.g., solid aerosolisable medium) accommodated in the second cavity 222a can be melted into a flowable state and flow into the atomization core 230, and then can be further heated by the atomization core 230 to generate the aerosol.

Further, in order to accelerate the solid aerosolisable medium to be melted into the flowable state, the atomization assembly 200 includes a preheating member 240 sleeved on an outer peripheral surface of the second pot body 222 and electrically connected to the circuit board 320 of the power supply assembly 300. The preheating member 240 is configured to preheat the aerosolisable medium accommodated in the second cavity 222a, and the solid aerosolisable medium is accelerated to be melted and flows into the atomization core 230, thus the atomization core 230 can more fully heat the aerosolisable medium to generate the aerosol.

In one embodiment, the preheating member 240 is a flexible printed circuit (FPC) heating cable, which has excellent flexibility, light weight, thin thickness, and good bendability, and can be tightly attached to an outer surface of the heating pot 220. When the preheating member 240 is powered on, the heat can be quickly transferred to the second cavity 222a, and the solid aerosolisable medium in the second cavity 222a can be quickly heated to a flowable state. The atomization core 230 is made of ceramic material, which has excellent heat resistance performance and good oil guiding and locking functions, the aerosolisable medium in the flowable state can be evenly immersed in the ceramic atomization core 230. Once the user starts to inhale, each inhalation of the aerosol can maintain a degree of taste consistency, and the atomization core 230 made of the ceramic material can completely release the rich taste, and the taste of the inhalation is improved.

Continuing to refer to FIG. 7, in some embodiments, the main body 210 of the atomization assembly 200 includes a box body 211 and a first sealing ring 212 connected to each other. The box body 211 is attached to the groove wall of the mounting groove 104, and at least a portion of the first sealing ring 212 is inserted into the box body 211. A part of an inner wall of the box body 211 and an inner wall of the first sealing ring 212 cooperatively form the atomization cavity 203. The heating pot 220 is inserted into first sealing ring 212. The box body 211 is made of hard plastic, and is configured to protect the parts in the atomization assembly 200. The first sealing ring 212 is made of silica gel, and is configured to seal the aerosolisable medium and parts in the atomization assembly 200, and is also configured to further prevent the condensate in the main air channel 401 from flowing back into the atomization cavity 203.

As shown in FIG. 6, the air inlet hole 201 is formed on the box body 211, and the locking groove 204 is formed on the box body 211. In one embodiment, the air inlet hole 201 is provided on a back side of the box body 211 (a side facing the heating pot 220 is a front side). A flow direction of the air at the air inlet hole 201 into the atomization cavity 203 is parallel to the axial direction of the mounting groove 104.

In other embodiments, the air inlet hole 201 may also be provided on a lateral side of the box body 211. When the atomization assembly 200 is located in the mounting groove 104, the air inlet hole 201 faces a side wall of the mounting groove 104. At this time, the external air may flow to the air inlet hole 201 through a gap between the atomization assembly 200 and the mounting groove 104, and then flow into the atomization assembly 200. In one embodiment, a through hole may be additionally formed on the side wall of the mounting groove 104 at a position corresponding to the air inlet hole 201, to allow external air to enter the atomization cavity 203.

As shown in the embodiment of FIG. 7, the first sealing ring 212 is completely inserted into the box body 211. At this time, the atomization assembly 200 and the housing 100 are sealed by the second sealing member 600. In this embodiment, the air passing hole 102 is formed on the second sealing member 600 and extends through the opposite sides of the second sealing member 600. The second sealing member 600 forms a part of the groove wall of the mounting groove 104, and one end of the air vent pipe 400 away from the mouthpiece 105 is inserted into the air passing hole 102 formed on the second sealing member 600. When the atomization assembly 200 is inserted into the mounting groove 104, one side of the second sealing member 600 abuts against the box body 211 of the atomization assembly 200, and the air vent hole 202 is formed on the box body 211, and the air passing hole 102 and the air vent hole 202 are in communication with each other.

In other embodiments, in order to make the electronic atomization device 10 have better connectivity and airtightness, a sealing structure is further provided between the atomization assembly 200 and the housing 100. In one embodiment, the sealing structure is arranged between the air passing hole 102 and the air vent hole 202, and is configured to seal a connection gap between the groove wall of the mounting groove 104 and the box body 211 of the atomization assembly 200, to prevent the aerosol generated by the atomization assembly 200 heating and atomizing the aerosolisable medium from overflowing from the connection gap when flowing through the air vent hole 202 and the air passing hole 102, to affect the taste of inhalation of the user.

In one embodiment, the second sealing member 600 slightly protrudes from the side wall of the mounting groove 104 toward the mounting groove 104, that is, the sealing structure is a portion of the second sealing member 600 slightly protruding from the side wall of the mounting groove 104. Therefore, when the atomization assembly 200 is inserted into the mounting groove 104, the second sealing member 600 can abut against the box body 211 of the atomization assembly 200 more tightly, and the sealing performance is improved.

In other embodiments, the atomization assembly 200 may be a detachable consumable, when the electronic atomization device 10 is not used, or when the aerosolisable medium is exhausted and the atomization assembly 200 needs to be replaced, the atomization assembly 200 will often be plugged in and out of the mounting groove 104, and the box body 211 of the atomization assembly 200 will often have friction with the second sealing member 600. After a long time, the sealing performance of the second sealing member 600 may be reduced due to abrasion. If the second sealing member 600 is to be replaced, the housing 100 needs to be disassembled, and the second sealing member 600 and the air vent pipe 400 need to be disassembled from each other. Therefore, it will be more troublesome to replace the second sealing member 600.

In order to solve the above problem, referring to FIG. 8 and FIG. 9, in another embodiment, the second sealing member 600 abuts against a portion of the housing 100 where the mounting groove 104 is formed. In other words, the second sealing member 600 abuts against a side of the mounting groove 104 facing the accommodation cavity 103. The air passing hole 102 is formed on a portion of the housing 100 where the groove wall of the mounting groove 104 is formed. The box body 211 is provided with the air inlet hole 201 and an air passing groove 2112 that are in communication with each other, and the air vent hole 202 is provided on the first sealing ring 212. The box body 211 is provided with an insertion groove 2114 in communication with the air passing hole 102. At least a portion of the first sealing ring 212, that is, at least a portion of the first sealing ring 212 forming the air vent hole 202, is embedded in the insertion groove 2114, and the air vent hole 202 is located between the air passing groove 2112 and the air passing hole 102, and is in communication with the air passing groove 2112 and the air passing hole 102. In one embodiment, as shown in FIG. 10, a top wall of the box body 211 is provided with a through hole 2113 extending through the top wall of the box body 211. The box body 211 further includes an insertion portion 2111 therein, and the air passing groove 2112 extends through two opposite sides of the insertion portion 2111. The insertion portion 2111 and the groove wall of the mounting groove 104 cooperatively form the insertion groove 2114. When the portion of the first sealing ring 212 provided with the air vent hole 202 is embedded in the insertion groove 2114, the portion of the first sealing ring 212 provided with the air vent hole 202 is exposed out of the box body 211.

Further, as shown in FIG. 6 and FIG. 8, the atomization assembly 200 further includes a second sealing ring 213 provided on a side of the first sealing ring 212 away from the insertion portion 2111 and surrounding the air vent hole 202, and the second sealing ring 213 abuts against the groove wall of the mounting groove 104 (that is, abuts against a portion of the housing 100 forming the groove wall of the mounting groove 104). The second sealing ring 213 is the sealing structure provided between the atomization assembly 200 and the housing 100. In this way, the sealing structure is arranged on the atomization assembly 200, and the atomization assembly 200 and the groove wall of the mounting groove 104 can form a better seal, even if the atomization assembly 200 often needs to be plugged in and out of the mounting groove 104, causing the abrasion of the first sealing ring 212 or the second sealing ring 213 and resulting in a decrease in the sealing performance, the first sealing ring 212 can be replaced at the same time when the atomization assembly 200 is replaced. In one embodiment, the second sealing member 600 does not need to be additionally replaced, which is convenient for the user to operate.

It should be understood that the second sealing ring 213 may be fixed to the first sealing ring 212, or may be detachably connected to the first sealing ring 212. When the second sealing ring 213 is fixed to the first sealing ring 212, the atomization assembly 200 can be easily assembled as a whole. When the second sealing ring 213 is detachably connected to the first sealing ring 212, only the second sealing ring 213 can be replaced when abrasion occurs.

In addition, two sealing rings 212 may be provided, one first sealing ring 212 is completely sleeved on the box body 211, and the other first sealing ring 212 is inserted into the box body 211, which can also achieve that it does not having to additionally replace the second sealing member 600 when the sealing performance between the atomization assembly 200 and the housing 100 is reduced.

In the above embodiment, the first anti-rotation surface 205 is formed on a side surface of the portion of the first sealing ring 212 embedded in the insertion slot 2114, and the electrode contact 206 and the air vent hole 202 are both provided on the first anti-rotation surface 205. By arranging the electrode contact 206 on the first anti-rotation surface 205, the electrode 321 can be more tightly contact with the electrode contact 206, to avoid the occurrence of poor contact.

Further, in order to insert the atomization assembly 200 to an appropriate depth in the mounting groove 104 and avoid the atomization assembly 200 being inserted too shallowly or too deeply that cause the air passing hole 102 and the air vent hole 202 to be unable to be aligned, or cause the electrode 321 to be unable to be in contact with the electrode contact 206, the box body 211 has a step portion 2115 surrounding a central axis of the box body 211. The step portion 2115 abuts against one side of the housing 100. The step portion 2115 is configured to limit the position of the atomization assembly 200, and the atomization assembly 200 can be inserted to a depth at which the air passing hole 102 is aligned with the air vent hole 202 and the electrode 321 is completely in contact with the electrode contact 206.

Further, as shown in FIG. 4, one end of the atomization assembly 200 is provided with an opening 207 facing the second cavity 222a of the heating pot 220. The aerosolisable medium can be conveniently filled into the second cavity 222a of the heating pot 220 from the opening 207. The electronic atomization device 10 further includes a tank cover 250. The tank cover 250 is detachably provided at a position of the opening 207 and is configured to close the opening 207. When the aerosolisable medium is placed into the heating pot 220 before the electronic atomization device 10 leaves the factory, it only needs to open the tank cover 250, place the solid aerosolisable medium into the accommodation cavity 103 of the heating pot 220 through the opening 207, and then close the tank cover 250.

In one embodiment, referring to FIG. 4, the central axis of the heating pot 220 and the central axis of the air vent pipe 400 are perpendicular to each other (i.e., the central axis of the mounting groove 104 and the central axis of the main air channel 401 are perpendicular to each other). In this way, when the electronic atomization device 10 is held by the user for horizontal inhalation (i.e., when the opening 207 of the atomization assembly 200 is upward), the solid aerosolisable medium becomes the flowable state under the preheating action of the preheating member 240, and the aerosolisable medium in the flowable state further generates the aerosol under the heating of the atomization core 230, and a flow path of the aerosolisable medium in the flowable state is vertical, and an outflow path of the aerosol is horizontal. In this case, the aerosolisable medium in the flowable state can enter the atomization core 230 more smoothly under the action of gravity, and the aerosolisable medium can be atomized more thoroughly when being heated and atomized by the atomization core 230, to reduce the residue of the aerosolisable medium and avoiding the blockage of the main air channel 401. In one embodiment, through the above arrangement, the power supply assembly 300 can be arranged by fully utilizing a space inside the housing 100 in a flowing direction of the aerosolisable medium, and the internal structure of the electronic atomization device 10 is more compact, to achieve that the appearance of the electronic atomization device is more compact and flattened.

In addition, in order to enable the user to conveniently control an operating state of the electronic atomization device 10, that is, to conveniently control the electronic atomization device 10 to be switched from a preheating state to a heating state, and to switch from the heating state to a non-operating state in which the electronic atomization device 10 does not operate, referring to FIGS. 2 and 4, the housing 100 further includes a button 700 on a side away from the opening 207 of the atomization assembly 200 for the user to switch between the above operating states. The button 700 is electrically connected to the circuit board 320 and can move relative to the housing 100 when pressed by the user, to sequentially drive the circuit board 320 to control the preheating member 240 to be turned on and off and to control the atomization core 230 to be turned on and off, respectively.

In this way, the opening 207 of the atomization assembly 200 is arranged opposite to the button 700, and the electronic atomization device 10 is more user-friendly in design, and the user's operation is more in line with people's operating habits. During operation, the user only needs to hold the housing 100 with his hand, the electronic atomization device 10 can be easily controlled to be in the heating state, the preheating state or the non-operating state by pressing the button 700 with a thumb or toggling the button 700. Compared with the button 700 being arranged on the same side as the opening 207 of the atomization assembly 200 or on a side opposite to the opening 207 of the atomization assembly 200, the electronic atomization device 10 is more suitable for the user to operate. In addition, by using the button 700 to control the electronic atomization device 10 to switch among the non-operating state, the preheating state, and the heating state, an airflow sensor is not required to be provided in the atomization assembly 200, and the user can drive the battery 310 to supply power to the atomization assembly 200 only by applying a force to the button 700. When no force is applied to the button 700, the battery 310 cannot supply power to the atomization assembly 200 to turn on the atomization assembly 200, and the user can use the electronic atomization device 10 to perform inhalation more accurately than using an airflow sensor, to reduce the occurrence of dry burning caused by false triggering. Further, since there is no need to provide the airflow sensor, the structure of the atomization assembly 200 is simple, and there is no need to provide an auxiliary air channel connected to the airflow sensor and in communication with the main air channel 401, and the atomized aerosol is prevented from remaining in the auxiliary air channel. Therefore, the relatively expensive solid aerosolisable medium can be fully atomized and inhaled, and unnecessary waste of the aerosolisable medium is reduced.

The electronic atomization device 10 of the above embodiment is operated as follows:

• • Step 1, the button 700 is pressed once to drive the circuit board 320 to control the preheating member 240 to preheat the heating pot 220 for at least 5 seconds, and the solid aerosolisable medium in the heating pot 220 is melted to form a fluid aerosolisable medium and penetrates into the atomization core 230.
  • Step 2, the user continuously presses the button 700 to drive the circuit board 320 to control the atomization core 230 to operate and performs inhalation through the air outlet hole 101. When the atomization core 230 operates, the atomization core 230 further heats the flowable aerosolisable medium flowing into the atomization core 230 to generate an aerosol for the user to inhale.
  • Step 3, the user releases the button 700 and stops inhaling to complete one inhalation action, the atomization core 230 also stops operating, and the electronic atomization device 10 enters the non-operating state. When the user needs to inhale again, the step 2 and the step 3 are repeated.

The above-mentioned embodiments do not constitute a limitation on the protection scope of the solution. Any modifications, equivalent replacements and improvements made within the spirit and principles of the above-mentioned embodiments shall be included within the protection scope of this solution.
