[0052] As used herein, the terms "first", "second", and the like are used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationships of the technical features indicated.

[0053] As Figures 1-6 shown, an embodiment of the electronic atomization device includes a device body 100 and a liquid storage component 200, and the number of the liquid storage component 200 can be one or more.

[0054] The device body 100 includes a first housing 101, which can be composed of multiple components, such as a main housing 101a and a top cover 101b arranged at the top end of the main housing 101a, or can be integrally formed.

[0055] The top end of the first housing 101 is provided with a suction nozzle 102. The suction nozzle 102 can be integrally formed with the first housing 101 or formed separately. The suction nozzle 102 is used for a user to inhale the aerosol generated by atomization.

[0056] A liquid storage cavity 103 for storing a first liquid substrate is formed in the first housing 101. The first liquid substrate can be a liquid including a tobacco-containing substance containing volatile tobacco flavoring components, or can be a liquid including a non-tobacco substance. For example, the liquid substrate can include water, a solvent, ethanol, a plant extract, a flavoring agent, or a vitamin mixture. The flavoring agent can include menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but is not limited thereto. The flavoring agent can include components capable of providing a user with a variety of flavors or tastes. The vitamin mixture can be a substance mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the first liquid substrate can include an aerosol forming agent such as glycerin and propylene glycol.

[0057] The liquid storage cavity 103 is provided with a liquid storage medium 103a, the upper end of the liquid storage cavity 103 is provided with a sealing member 103b, and the lower end of the liquid storage cavity 103 is provided with a sealing member 103c. The upper and lower ends of the liquid storage cavity 103 are sealed by the sealing member 103b and the sealing member 103c.

[0058] The liquid storage medium 103a is made of, for example, a fibrous material or a porous material. As Figure 7 shown, the liquid storage medium 103a is generally in a tubular structure. The liquid storage medium 103a can absorb and hold the first liquid substrate and provide the first liquid substrate to the atomization core 104. When the liquid storage medium 103a is saturated after liquid injection, the content of the liquid substrate in the liquid storage medium 103a is between 0.1 ml and 2 ml, such as 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml, etc. The space between the end face of the upper end of the liquid storage medium 103a and the sealing member 103b is defined as an air portion.

[0059] The first housing 101 is provided with an atomization core 104 for atomizing a liquid substrate to generate an aerosol.

[0060] As shown in the drawings, the atomization core 104 includes a liquid guide element 104a and a heating element 104b. The liquid guide element 104a can absorb the liquid substrate in the liquid storage medium 103a and deliver the liquid substrate to the heating element 104b. The heating element 104b can be heated by an electric current supply and deliver heat to the liquid substrate in contact with the heating element 104b to heat the liquid substrate, thereby generating an aerosol. Figure 8 The liquid guide element 104a is configured in a tubular structure, and it can be understood that it can also be a plate structure or other regular or irregular shapes. The liquid guide element 104a can be made of flexible fiber materials, such as cotton fiber, non-woven fabric, or sponge, etc. Alternatively, in other examples, the liquid guide element 104a can also be a rigid porous body, such as porous ceramic, porous glass, etc. The outer surface of the liquid guide element 104a has a radially outward protruding portion 104a1.

[0061] The heating element 104b is arranged close to the inner surface of the liquid guide element 104a, which can be attached to the inner surface of the liquid guide element 104a, or partially or completely embedded in the liquid guide element 104a. The heating element 104b can be a resistance heating net, a resistance heating coil, etc. The heating element 104b can be made of materials with suitable resistance temperature coefficient characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In an example, the heating element 104b can be wound from a sheet or net-shaped base material, and the wound heating element 104b is a non-closed tubular structure in the circumferential direction, i.e. a tubular structure with a side opening extending in the length direction of the device body 100. The two ends of the heating element 104b are welded or arranged with conductive pins 104c and 104d for guiding an electric current on the heating element 104b. In other examples, the heating element 104b can be arranged to be wound around the structure of the liquid guide element 104a.

[0062] The first housing 101 is also provided with an airflow passage 105 to transport the aerosol generated by the atomization core 104 to the mouthpiece 102 to be inhaled by the user. The lower end of the airflow passage 105 is in communication with the air inlet, which can be arranged on the bottom wall of the first housing 101; the upper end of the airflow passage 105 is connected to the mouthpiece 102, i.e. in communication with the air outlet (specifically, refer to the dashed arrow S1 shown in the drawings).

[0063] As shown in the drawings, the atomization core 104 includes a liquid guide element 104a and a heating element 104b. The liquid guide element 104a can absorb the liquid substrate in the liquid storage medium 103a and deliver the liquid substrate to the heating element 104b. The heating element 104b can be heated by an electric current supply and deliver heat to the liquid substrate in contact with the heating element 104b to heat the liquid substrate, thereby generating an aerosol.

[0064] Figure 9 ​As shown, the first housing 101 is provided with a connecting tube 105a, and a partial airflow passage 105 is defined by a hollow portion inside the connecting tube 105a. The connecting tube 105a extends along an axial direction of the liquid storage cavity 103. An upper end of the connecting tube 105a is connected with the sealing member 103b, and a lower end of the connecting tube 105a is connected with the sealing member 103c. The connecting tube 105a is preferably made of a thin rigid material, such as glass fiber material, stainless steel, etc.

[0065] In a preferred implementation, the liquid storage medium 103a is sleeved on the connecting tube 105a, and an inner diameter of the liquid storage medium 103a is slightly smaller than an outer diameter of the connecting tube 105a, so that the liquid storage medium 103a is tightly sleeved on the connecting tube 105a. The atomization core 104 is arranged in the connecting tube 105a. The atomization core 104 is coaxially arranged with the connecting tube 105a. The side wall of the connecting tube 105a is further provided with a liquid guide opening 105a1 arranged near the lower end of the connecting tube 105a, the liquid storage medium 103a covers the liquid guide opening 105a1, and a portion of the liquid guide element 104a is exposed in the liquid storage cavity 103 through the liquid guide opening 105a1, so that the portion of the liquid guide element 104a is arranged close to the liquid storage medium 103a and keeps contact with the liquid storage medium 103a, and thus the liquid matrix in the liquid storage cavity 103 flows into the atomization core 104 through the liquid guide opening 105a1, i.e. is sucked by the liquid guide element 104a, and is atomized by the heating element 104b to generate the inhalable aerosol.

[0066] The side wall of the connecting tube 105a is further provided with a notch groove 105a2 extending from the lower end of the connecting tube 105a towards the upper end of the connecting tube 105a. The protruding portion 104a1 of the liquid guide element 104a extends into the notch groove 105a2, and thus is exposed in the liquid storage cavity 103. After assembly, the liquid storage medium 103a keeps contact with the protruding portion 104a1, and thus facilitates the liquid guide element 104a to suck the liquid matrix.

[0067] The first housing 101 is further provided with a circuit 106, which can control overall operation of the device body 100. In detail, the circuit 106 not only controls operation of the battery 107 and the atomization core 104, but also controls operation of other elements in the device body 100. In addition, the circuit 106 can determine whether the device body 100 can operate by checking states of components of the device body 100.

[0068] The circuit 106 includes at least one control unit. The control unit can include a logic gate array, or can include a combination of a general-purpose microcontroller and a memory for storing a program executable in the microcontroller. In addition, those skilled in the art should understand that the circuit 106 can include another type of hardware.

[0069] The battery cell 107 provides power for operating the device body 100. For example, the battery cell 107 can provide power for heating the heating element, and can provide power required for operating the circuit 106. In addition, the battery cell 107 can provide power required for operating other components provided in the device body 100.

[0070] The battery cell 107 can be a rechargeable battery or a disposable battery. The battery cell 107 can be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the battery cell 107 can be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery.

[0071] It should be noted that only components related to the present embodiment are shown in the drawings. It should be understood by those skilled in the art that the device body 100 can also include other general components in addition to the components shown. Figures 1-6 For example, a puff detector can also be provided in the first housing 101, for detecting a puffing action of a user and generating a corresponding electrical signal, i.e. detecting whether the device body 100 is puffed, so that the circuit 106, e.g. a control unit, controls the operation of the battery cell 107, the heating element 104b, etc. according to the electrical signal, e.g. controls the battery cell 107 to provide power to the heating element 104b, so that the heating element 104b heats the aerosol liquid substrate. The puff detector can employ a common pressure sensor, a differential pressure sensor, an air flow sensor, etc. The puff detector is in communication with the air flow passage 105, so that when the user puffs, the change in the puffing air flow can be sensed.

[0072] It should also be noted that in Figures 1-6 In the example shown, the above components are integrally formed, and the device body 100 is a common connected device. In other examples, the device body 100 includes an atomizer, and a power supply assembly detachably connected to the atomizer, the atomizer is commonly referred to as a cartridge, and the power supply assembly is commonly referred to as a stick; wherein the circuit 106, the battery cell 107 and the puff detector are in the power supply assembly; the mouthpiece 102, the liquid storage cavity 103 and the atomizing core 104 are in the atomizer, which is also feasible.

[0073] It should be understood in combination with Figures 11-13 that the liquid storage component 200 includes a second housing 201, which can be composed of multiple components, such as a main housing 201a, a bottom cover 201b, a sealing member 201c and a sealing member 201d.

[0074] The main housing 201a is connected with the bottom cover 201b. In a preferred embodiment, the main housing 201a is detachably connected with the bottom cover 201b, for example, snap connection. Part of the bottom cover 201b extends into the main housing 201a. The main housing 201a and the bottom cover 201b together define a liquid storage cavity 202 for storing the second liquid substrate. In a further embodiment, the bottom cover 201b is provided with a liquid injection port 201b1 through which the second liquid substrate can be injected into the liquid storage cavity 202; the liquid injection port 201b1 can be sealed by a sealing member or by other means, which are not limited in the present application. A sealing member 201c is arranged between the bottom cover 201b and the main housing 201a to prevent the second liquid substrate from leaking from the gap between the bottom cover 201b and the main housing 201a. In a preferred embodiment, the outer surface of the bottom cover 201b is provided with a groove 201b2, and the sealing member 201c is annular and at least partially received in the groove 201b2, thereby achieving sealing between the bottom cover 201b and the main housing 201a.

[0075] Similar to the first liquid substrate, the second liquid substrate can be a liquid including a tobacco-containing substance containing volatile tobacco flavor components, or a liquid including a non-tobacco substance. For example, the liquid substrate can include water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture. The flavor can include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent can include components capable of providing a user with a variety of flavors or tastes. The vitamin mixture can be a substance mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the second liquid substrate can include an aerosol forming agent such as glycerin and propylene glycol.

[0076] It should be noted that the components or properties of the second liquid substrate can be different from or the same as those of the first liquid substrate. For example, in some examples, the second liquid substrate and the first liquid substrate are different in composition or concentration. For example, in other examples, the second liquid substrate and the first liquid substrate are completely the same in composition, the second liquid substrate can be part of a certain liquid formulation, and the first liquid substrate can be another part of the certain liquid formulation. The second liquid substrate can be introduced into the liquid storage cavity 103 as a supplement to the first liquid substrate, thereby increasing the number of puffs of the electronic atomization device.

[0077] The volume of the liquid storage cavity 202 is greater than that of the liquid storage cavity 103. Generally, the capacity of the second liquid medium stored in the liquid storage cavity 202 is between 2ml and 10ml, such as 2ml, 4ml, 5ml, 6ml, 8ml, 10ml, etc. It can be understood that the volume of the liquid storage cavity 202 is slightly greater than the capacity of the second liquid medium stored. In this way, after the second liquid medium is stored in the liquid storage cavity 202, it can be divided into two parts, one part is an air part, and the other part is a liquid medium part. Generally, no liquid storage medium is arranged in the liquid storage cavity 202.

[0078] The liquid storage component 200 is independent of the device main body 100, for example, the product is in a packaged state or an unused state, the liquid storage component 200 is separated from the device main body 100, and the user can assemble the liquid storage component 200 on the device main body 100 before use. In an example, the liquid storage component 200 is detachably connected with the device main body 100, that is, the second shell 201 is detachably connected with the first shell 101, for example, snap connection, magnetic connection, etc. In an example, the liquid storage component 200 is not re-detachable once connected with the device main body 100.

[0079] The first shell 101 is also provided with a receiving cavity 108 for receiving or accommodating at least part of the second shell 201. Specifically, the shape of the receiving cavity 108 is adapted to the shape of the second shell 201, and the receiving cavity 108 is a notch groove through part of the left side wall and part of the top wall of the first shell 101, and the second shell 201 can be assembled on the first shell 101 from the left side of the first shell 101. The inner wall of the receiving cavity 108 is provided with a clamping buckle 108a, and the outer wall of the second shell 201 is provided with a clamping hole 201a1, and the clamping buckle 108a and the clamping hole 201a1 are matched to realize the snap connection of the second shell 201 and the first shell 101. It should be noted that the number of clamping buckles 108a and clamping holes 201a1 is not limited here, and the position can be adjusted as needed. After the second shell 201 is connected with the first shell 101, the outer shell of the device main body 100 is jointly defined. It can be understood that the connection mode of the second shell 201 and the first shell 101 is not limited to the above case.

[0080] In an example, a guide mechanism can be provided between the device main body 100 and the liquid storage component 200, so as to facilitate the assembly of the second shell 201 on the first shell 101 in the direction from the left side of the first shell 101 to the right side of the first shell 101. For example, a sliding block 108b is arranged on the inner wall of the receiving cavity 108, and a sliding groove 201a2 is arranged on the second shell 201 of the liquid storage component 200, and the sliding block 108b can slide in the sliding groove 201a2, so as to assemble the second shell 201 on the first shell 101.

[0081] When the second shell 201 is connected with the first shell 101, the liquid storage cavity 103 and the liquid storage cavity 202 are arranged in sequence along the width direction of the electronic atomization device. The liquid storage cavity 103 is arranged close to the right side of the electronic atomization device, and the liquid storage cavity 202 is arranged close to the left side of the electronic atomization device. It can be understood that the arrangement of the liquid storage cavity 103 and the liquid storage cavity 202 is not limited to the above case.

[0082] In an example, when the second shell 201 is connected with the first shell 101, an air passage for air flow and a liquid passage for liquid substrate flow can be established between the first liquid storage cavity 103 and the second liquid storage cavity 202.

[0083] Specifically, the first shell 101 is provided with a connector 109, and the second shell 201 is provided with a plug-in interface 201b3.

[0084] The connector 109 is located in the accommodation cavity 108, and one end of the connector 109 protrudes from the cavity wall of the accommodation cavity 108, for example, protrudes from the right cavity wall of the accommodation cavity 108. The connector 109 extends in the width direction of the first shell 101 towards the direction away from the right cavity wall of the accommodation cavity 108. The second through hole 109a and the first through hole 109b are formed in the connector 109. The second through hole 109a and the first through hole 109b are spaced apart in the length direction of the first shell 101, for example, separated by a partition 109c. One end of the second through hole 109a communicates with the first liquid storage cavity 103, and the other end of the second through hole 109a communicates with the outside of the first shell 101. One end of the first through hole 109b also communicates with the first liquid storage cavity 103, and the other end of the first through hole 109b communicates with the outside of the first shell 101.

[0085] One end of the plug-in interface 201b3 is arranged close to the bottom of the second liquid storage cavity 202 and communicates with the second liquid storage cavity 202, and the other end of the plug-in interface 201b3 communicates with the outside of the second shell 201.

[0086] When the second shell 201 is connected with the first shell 101, the connector 109 is plugged into the plug-in interface 201b3, thereby connecting the first liquid storage cavity 103 and the second liquid storage cavity 202. In this way, the liquid substrate in the second liquid storage cavity 202 can supplement the consumed liquid substrate through the second through hole 109a to the first liquid storage cavity 103. When the liquid substrate in the second liquid storage cavity 202 is reduced, the air in the first liquid storage cavity 103 can flow into the second liquid storage cavity 202 through the first through hole 109b, thereby balancing the pressure difference between the first liquid storage cavity 103 and the second liquid storage cavity 202, so that the second liquid substrate stored in the second liquid storage cavity 202 can flow smoothly to the first liquid storage cavity 103, and supplement the consumed liquid substrate to the first liquid storage cavity 103 in time.

[0087] As can be seen from the above, the second through hole 109a defines a liquid channel, and the first through hole 109b defines an air channel. It is understandable that the second through hole 109a can be used together with other components to define a liquid channel, and the first through hole 109b can do the same.

[0088] The seal 201d is at least partially housed within the insertion interface 201b3. The seal 201d has a through-hole 201d1, within which a puncturable sealing membrane 201d2 is disposed. When the second housing 201 is connected to the first housing 101, the connector 109 can extend into the through-hole 201d1 and puncture the sealing membrane 201d2, thereby connecting the first liquid storage chamber 103 and the second liquid storage chamber 202. After the second housing 201 is connected to the first housing 101, the seal 201d is located between the outer wall of the connector 109 and the inner wall of the insertion interface 201b3, thus forming a seal.

[0089] In a further implementation, a liquid guiding element 110 is also provided in the liquid storage chamber 103. For example... Figure 10 As shown, the liquid guiding element 110 is generally tubular in structure. The liquid guiding element 110 and the liquid storage medium 103a are arranged sequentially along the axial direction of the liquid storage cavity 103. The liquid storage medium 103a is positioned near the first through hole 109b, and the liquid guiding element 110 is positioned near the second through hole 109a, meaning the liquid guiding element 110 communicates with the liquid channel. The second through hole 109a is covered by the liquid guiding element 110. The upper surface of the liquid guiding element 110 is in contact with the lower surface of the liquid storage medium 103a, the lower surface of the liquid guiding element 110 is in contact with the bottom of the liquid storage cavity 103, and the outer surface of the liquid guiding element 110 is in contact with the wall defining the liquid storage cavity 103. In this way, when the second liquid matrix in the storage chamber 202 flows to the storage chamber 103 through the liquid channel, it can be absorbed by the liquid guiding element 110 and transferred to the storage medium 103a, and then indirectly transferred to the liquid guiding element 104a in the atomizing core 104, that is, absorbed by the liquid guiding element 104a in the atomizing core 104. This arrangement allows the second liquid matrix stored in the storage chamber 202 to flow to the atomizing core 104 more smoothly, avoiding the problem of abnormal noise caused by the user's inhalation due to a fast liquid supply rate and the problem of the user easily inhaling the liquid matrix.

[0090] In the above implementation, the material of the liquid guiding element 110 can be the same as or different from that of the liquid storage medium 103a. The density of the liquid guiding element 110 must be greater than that of the liquid storage medium 103a. This ensures that, on the one hand, the liquid guiding element 110 can strongly absorb the liquid matrix in the liquid channel, allowing the liquid matrix in the liquid guiding element 110 to be smoothly transferred to the liquid storage medium 103a; on the other hand, the liquid guiding element 110 can slow down the oversaturation of the liquid storage medium 103a, reducing the probability of liquid matrix leakage.

[0091] In the above implementation, the liquid guiding element 110 and the liquid storage medium 103a can be integrated, i.e., formed as one piece. The integrated component can be referred to as a liquid guiding element or a liquid storage medium, i.e., capable of absorbing the liquid medium in the liquid channel and transferring it to the liquid guiding element 104a, and at the same time capable of absorbing and retaining the liquid medium.

[0092] In the above implementation, there can be a gap between the cavity wall of the liquid storage cavity 103 and the outer surface of the liquid storage medium 103a, so that air can pass through the gap between the cavity wall of the liquid storage cavity 103 and the outer surface of the liquid storage medium 103a to communicate with the air portion of the liquid storage cavity 103, achieving air exchange.

[0093] In the above implementation, the liquid guiding element 110 is sleeved on the connecting pipe 105a, i.e., the liquid guiding element 110 is arranged around the connecting pipe 105a. The liquid guiding element 110 is located between the liquid channel and the atomizing core 104. The inner diameter of the liquid guiding element 110 is greater than the outer diameter of the connecting pipe 105a, so that a spacing space is formed between the inner surface of the liquid guiding element 110 and the outer surface of the connecting pipe 105a. In this way, the liquid guiding element 110 does not directly contact the atomizing core 104, and at the same time the liquid storage medium 103a only contacts a part of the atomizing core 104, avoiding the atomizing core 104 from being too saturated with the liquid, and reducing the risk of leakage of the liquid medium from the liquid storage cavity 103 to the outside.

[0094] In the above implementation, since the protruding portion 104a1 of the liquid guiding element 104a extends into the notch groove 105a2 of the connecting pipe 105a, it is exposed in the spacing space between the inner surface of the liquid guiding element 110 and the outer surface of the connecting pipe 105a, and the liquid medium in the spacing space can be absorbed by the liquid guiding element 104a, thereby reducing the risk of leakage of the liquid medium from the liquid storage cavity 103 to the outside.

[0095] In further implementations, a liquid guiding element 111 is further provided in the liquid channel, e.g., the liquid guiding element 111 is arranged in the second through hole 109a, one end of the liquid guiding element 111 is arranged close to the liquid guiding element 110 and abuts or contacts the liquid guiding element 110, and the other end of the liquid guiding element 111 is arranged close to the other end of the connector 109 or extends out of the connector 109. In this way, the liquid medium stored in the second liquid storage cavity 202 can be absorbed by the liquid guiding element 111 and transferred to the liquid guiding element 110, thereby timely supplementing the consumed liquid medium to the first liquid storage cavity 103.

[0096] The liquid guiding element 111 is made of or comprises a flexible fiber such as cotton fiber, non-woven fabric, or sponge, etc. In use, when the liquid base stored in the second liquid storage cavity 202 flows to the first liquid storage cavity 103 through the liquid passage, the liquid guiding element 111 can absorb and store the liquid base by capillary adsorption to adjust the flow rate of the liquid base flowing from the second liquid storage cavity 202 to the first liquid storage cavity 103, so as to prevent the liquid base from flowing too fast to cause leakage, and release the liquid base to ensure the supply rate when the liquid base flows slowly.

[0097] In further implementations, an air regulating member 112 is further included and located at least partially in the air passage. The air in the first liquid storage cavity 103 or the second liquid storage cavity 202 can flow through the gap between the outer wall of the air regulating member 112 and the inner wall of the air passage.

[0098] Specifically, the air regulating member 112 can be made of a flexible material such as silica gel. The air regulating member 112 is located in the first through hole 109b, for example, the air regulating member 112 is arranged close to the other end of the first through hole 109b, i.e. close to the outside of the first shell 101. In this way, the air can flow through the gap between the outer wall of the air regulating member 112 and the inner wall of the first through hole 109b.

[0099] In an example, at least one groove 109b1 is arranged on the inner wall of the first through hole 109b, and the groove 109b1 defines the boundary of the aforementioned gap, so that the air can flow through the groove 109b1. The groove 109b1 extends in the direction of air flow and the extension length of the groove 109b1 is greater than the extension length of the air regulating member 112. The depth of the groove 109b1 is between 0.1 mm and 0.5 mm, or between 0.1 mm and 0.4 mm, or between 0.1 mm and 0.3 mm.

[0100] It can be understood that the groove can also be arranged on the outer wall of the air regulating member 112.

[0101] It should be noted that the device main body 100 and the liquid storage component 200 are independent of each other. Before the device main body 100 and the liquid storage component 200 are connected (i.e. before the first shell 101 and the second shell 201 are connected), the device main body 100 can be used and sucked alone, and the atomizing core 104 only atomizes the first liquid base. After the device main body 100 and the liquid storage component 200 are connected (i.e. after the first shell 101 and the second shell 201 are connected), the atomizing core 104 can atomize both the first liquid base and the second liquid base. In other examples, the atomizer or the cartridge can be used in combination with the power assembly (or the cigarette rod) first, and then used in combination with the liquid storage component 200.

[0102] It should be noted that the above-mentioned joint is arranged on the second shell 201, and the insertion interface is arranged on the first shell 101, which is also feasible.

[0103] It should be noted that in other examples, it is also possible that the electronic atomization device cannot be used and smoked before the second shell 201 is connected with the first shell 101. That is, only after the second shell 201 is connected with the first shell 101, the electronic atomization device can be used and smoked, at which time the atomization core 104 can atomize both the first liquid substrate and the second liquid substrate.
