[0077] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "upper", "lower", "left", "right", "inside", "outside" and similar expressions used in this specification are for illustrative purposes only.

[0078] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0079] As used herein, the terms 'upstream' and 'downstream' describe the relative positions of components, or parts of components, in the electronic atomization device in the direction of the flow of the suction airflow.

[0080] As shown in Figures 1 to 4, the electronic atomization device 100 provided in one embodiment of the present application includes a first shell assembly 101. The first shell assembly 101 can be composed of multiple components, such as a main shell, a top cover arranged at the top end of the main shell, and a bottom cover arranged at the bottom end of the main shell. The first shell assembly 101 can also be formed as one piece.

[0081] A nozzle 102 is provided at the top of the first housing assembly 101. The nozzle 102 can be integrally formed with the first housing assembly 101 or can be formed separately. The nozzle 102 is used for a user to inhale the aerosol generated by atomization.

[0082] The first housing assembly 101 is formed with the first liquid storage chamber 103 that is used to store the first liquid matrix.The first liquid matrix can be the liquid that comprises the tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.Spice can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user.Vitamin mixture can be for being mixed with at least a material among vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.In addition, the first liquid matrix can comprise the aerosol forming agent such as glycerol and propylene glycol.

[0083] Generally, the capacity of the first liquid matrix stored in the first liquid storage chamber 103 ranges from 0.1 ml to 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, etc. It is understood that the volume of the first liquid storage chamber 103 is slightly larger than the capacity of the stored first liquid matrix. Thus, after the first liquid matrix is ​​stored in the first liquid storage chamber 103, it can be divided into two parts, as shown in FIG5 : one part is the air portion A1 above the liquid surface A, and the other part is the liquid matrix portion A2 below the liquid surface A.

[0084] An atomizing assembly 104 is further provided in the first housing assembly 101 , and the atomizing assembly 104 is used to atomize the liquid matrix to generate an aerosol.

[0085] In one example, the atomizing assembly 104 includes a liquid delivery unit and a heating element.

[0086] The liquid transfer unit can transfer the liquid matrix in the first liquid storage chamber 103 to the heating element. For example, the liquid transfer unit can be made of, but is not limited to, a porous material such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, or porous glass. The liquid transfer unit can be configured as a tubular structure, a plate structure, or other regular or irregular shapes.

[0087] The heating element is used to heat the atomized liquid matrix to generate an aerosol. The heating element can be a metal wire, a conductive track, a metal plate, a ceramic heater, etc., but is not limited thereto. In addition, the heating element can be composed of a conductive heating wire such as a nickel-chromium wire. The heating element can be made of a material with suitable resistance temperature coefficient characteristics, for example: stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. The heating element can be configured as a structure wrapped around the liquid transfer unit. The heating element can be heated by the supply of electric current and transfer heat to the liquid matrix in contact with the heating element to heat the liquid matrix, thereby generating an aerosol.

[0088] It should be noted that the atomizing assembly 104 is not limited to the above embodiment. In other examples, the heating element can also be a sensor that can be penetrated by a changing magnetic field and generate heat, or an infrared heater that radiates infrared rays. In another example, an ultrasonic atomizer can also be used instead.

[0089] An air flow channel 105 is further provided in the first housing assembly 101 to transmit the aerosol generated by the atomizing assembly 104 to the mouthpiece 102 for inhalation by the user.

[0090] In one example, the lower end of the air flow channel 105 is connected to the air inlet, and the air inlet can be provided at the bottom end of the first housing assembly 101; the upper end of the air flow channel 105 is connected to the suction nozzle 102, that is, it is connected to the air outlet (the dotted arrow in the figure is the direction of the air flow in part of the air flow channel 105). The first liquid storage chamber 103 is arranged around at least part of the air flow channel 105. The atomization assembly 104 is arranged in the air flow channel 105, or the atomization assembly 104 is configured as a tubular structure, and its internal hollow portion defines and forms part of the air flow channel 105. A liquid hole is provided on the air flow channel 105 to connect the first liquid storage chamber 103 and the atomization assembly 104, so that the liquid matrix in the first liquid storage chamber 103 can be transferred to the atomization assembly 104 and atomized.

[0091] A circuit 106 is also provided within the first housing assembly 101. This circuit 106 controls the overall operation of the electronic atomization device 100. Specifically, the circuit 106 controls not only the operation of the battery cell 107 and the atomization assembly 104, but also the operation of other components within the electronic atomization device 100. Furthermore, the circuit 106 can determine whether the electronic atomization device 100 is operational by checking the status of its components.

[0092] Circuit 106 includes at least one controller. The controller may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. In addition, those skilled in the art will appreciate that circuit 106 may include another type of hardware.

[0093] The battery cell 107 provides power for operating the electronic atomization device 100. For example, the battery cell 107 can provide power to heat the heating element and can provide power required to operate the circuit 106. In addition, the battery cell 107 can provide power required to operate other components provided in the electronic atomization device 100.

[0094] The battery cell 107 may be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, the battery cell 107 may be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery. The battery cell 107 may be a rechargeable battery or a disposable battery.

[0095] It should be noted that only the components related to this embodiment are shown in the figure. Those skilled in the art should understand that the electronic atomization device 100 may also include other common components in addition to the components shown in Figures 1 to 4. For example, a puff detector may also be provided in the first shell assembly 101 to detect the user's puffing action and generate a corresponding electrical signal, that is, to detect whether the electronic atomization device 100 is puffed, so that the circuit 106, such as a controller, controls the operation of the battery cell 107, the heating element, etc. according to the electrical signal, for example, controls the battery cell 107 to provide power to the heating element so that the heating element heats the atomized liquid matrix. The puff detector can adopt a common pressure sensor, a pressure differential sensor, an airflow sensor, and the like.

[0096] It should also be noted that in the examples of Figures 1-4 , the aforementioned components are integrally formed, and the electronic atomization device 100 is a typical one-piece device. In other examples, the electronic atomization device includes an atomizer, which is often referred to as a cartridge, and a power supply assembly detachably connected to the atomizer. The atomizer is often referred to as a cigarette cartridge, and the power supply assembly is often referred to as a cigarette rod. The circuit 106 , battery cell 107 , and puff detector are located in the power supply assembly, and the nozzle 102 , first liquid storage chamber 103 , and atomization assembly 104 are located in the atomizer. This is also feasible.

[0097] 1 to 4 , the liquid storage component 200 provided in one embodiment of the present application includes a second housing assembly 201 , which is composed of a main body 201 a and a top cover 201 b . The main body 201 a is a barrel-shaped structure, and the top cover 201 b is disposed on the top of the main body 201 a .

[0098] The second liquid storage chamber 202 that is used to store the second liquid matrix is ​​formed with in the second housing assembly 201.Similar to the first liquid matrix, the second liquid matrix can be the liquid that comprises the tobacco-containing material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture.Spice can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user.Vitamin mixture can be for being mixed with at least a material among vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.In addition, the second liquid matrix can comprise the aerosol forming agent as glycerol and propylene glycol.

[0099] It should be noted that the characteristics of the second liquid matrix and the first liquid matrix can be different or the same. For example, the second liquid matrix and the first liquid matrix have different constituents, or the second liquid matrix and the first liquid matrix have different concentrations. The second liquid matrix can be a part of a certain formula, and the first liquid matrix can be another part of a certain formula. In some examples, the second liquid matrix has the same composition or type as the first liquid matrix, and the second liquid matrix in the second liquid storage chamber 202 is supplemented in the first liquid storage chamber 103 as a liquid source, thereby increasing the liquid capacity in the first liquid storage chamber 103.

[0100] The volume of the second liquid storage chamber 202 is larger than that of the first liquid storage chamber 103. Generally, the volume of the second liquid matrix stored in the second liquid storage chamber 202 ranges from 2 ml to 10 ml, for example, 4 ml, 5 ml, 6 ml, 8 ml, and so on. It is understood that the volume of the second liquid storage chamber 202 is slightly larger than the volume of the stored second liquid matrix. Thus, after the second liquid matrix is ​​stored in the second liquid storage chamber 202, it can be divided into two parts: one part is the air portion above the liquid surface, and the other part is the liquid matrix portion below the liquid surface. This can be understood with reference to Figure 5.

[0101] The liquid storage component 200 is independent of the electronic atomization device 100. In one example, the liquid storage component 200 is detachably connected to the electronic atomization device 100, that is, the second housing component 201 is detachably connected to the first housing component 101. In another example, the liquid storage component 200 is not detachable after being connected to the electronic atomization device 100.

[0102] The first housing assembly 101 is provided with a first receiving cavity 108 for receiving or accommodating at least a portion of the second housing assembly 201. Specifically, the shape of the first receiving cavity 108 is adapted to the shape of the second housing assembly 201. The first receiving cavity 108 is a notch that penetrates a portion of the left side wall and a portion of the top wall of the first housing assembly 101. The second housing assembly 201 can be assembled to or retained on the first housing assembly 101 from the left side of the first housing assembly 101. The inner wall of the first receiving cavity 108 is provided with a snap connector 108a, and the outer wall of the second housing assembly 201 is provided with a snap connector 201c. The snap connector 108a cooperates with the snap connector 201c to achieve a snap connection between the second housing assembly 201 and the first housing assembly 101. It is understood that the connection method between the second housing assembly 201 and the first housing assembly 101 is not limited to the above situation.

[0103] When the second housing assembly 201 is connected to the first housing assembly 101, the first liquid storage chamber 103 and the second liquid storage chamber 202 are arranged in sequence substantially along the width direction of the electronic atomization device 100. The first liquid storage chamber 103 is arranged near the right end of the electronic atomization device 100, while the second liquid storage chamber 202 is arranged near the left end of the electronic atomization device 100.

[0104] When the second shell assembly 201 is connected to the first shell assembly 101, the air portion above the liquid surface of the first liquid storage chamber 103 is connected to the air portion above the liquid surface of the second liquid storage chamber 202, and the liquid matrix portion below the liquid surface of the first liquid storage chamber 103 is connected to the liquid matrix portion below the liquid surface of the second liquid storage chamber 202.

[0105] Specifically, please understand in conjunction with Figures 6 and 7 that the first shell assembly 101 also includes a first through hole 109 and a second through hole 110 that are spaced apart. One end of the first through hole 109 is connected to the liquid matrix portion below the liquid level of the first liquid storage chamber 103, and the other end of the first through hole 109 extends to the right end of the inner wall of the first receiving chamber 108. The second through hole 110 is located above the first through hole 109 in the longitudinal direction of the electronic atomization device 100, and one end of the second through hole 110 is connected to the air portion above the liquid level of the first liquid storage chamber 103, and the other end of the second through hole 110 extends to the right end of the inner wall of the first receiving chamber 108.

[0106] The second housing assembly 201 also includes a third through hole 203 and a fourth through hole 204 spaced apart. One end of the third through hole 203 communicates with the liquid matrix portion below the liquid level of the second liquid storage chamber 202, and the other end of the third through hole 203 protrudes from the outer surface of the right side end of the second housing assembly 201. The fourth through hole 204 is located above the third through hole 203 in the longitudinal direction of the electronic atomization device 100. One end of the fourth through hole 204 communicates with the air portion above the liquid level of the second liquid storage chamber 202, and the other end of the fourth through hole 204 protrudes from the outer surface of the right side end of the second housing assembly 201.

[0107] When the second housing assembly 201 is connected to the first housing assembly 101, at least a portion of the wall defining the third through hole 203 extends into the first through hole 109, thereby allowing the liquid matrix portion below the liquid surface of the first liquid storage chamber 103 to communicate with the liquid matrix portion below the liquid surface of the second liquid storage chamber 202; at least a portion of the wall defining the fourth through hole 204 extends into the second through hole 110, thereby allowing the air portion above the liquid surface of the first liquid storage chamber 103 to communicate with the air portion above the liquid surface of the second liquid storage chamber 202.

[0108] In this case, the third through hole 203 and / or the first through hole 109 define a liquid channel (first channel), one end of which communicates with the portion of the liquid matrix below the liquid level of the first liquid storage chamber 103, while the other end communicates with the portion of the liquid matrix below the liquid level of the second liquid storage chamber 202. The fourth through hole 204 and / or the second through hole 110 define an air channel (second channel), one end of which communicates with the air above the liquid level of the first liquid storage chamber 103, while the other end communicates with the air above the liquid level of the second liquid storage chamber 202. The air channel balances the air pressure between the first and second liquid storage chambers 103 and 202, allowing the second liquid matrix stored in the second liquid storage chamber 202 to flow smoothly through the liquid channel to the first liquid storage chamber 103, thereby promptly replenishing the consumed liquid matrix in the first liquid storage chamber 103.

[0109] In further implementation, as will be understood in conjunction with FIG4 , the third through hole 203 is disposed near the bottom wall of the second housing assembly 201, and the bottom wall of the second housing assembly 201 is inclined toward the third through hole 203, or the bottom wall of the second housing assembly 201 has an inclined surface 201a1 that is inclined toward the third through hole 203. This allows the liquid matrix in the second liquid storage chamber 202 to flow more efficiently into the first liquid storage chamber 103 rather than accumulating in the second liquid storage chamber 202, thereby avoiding waste of the liquid matrix.

[0110] In further implementation, please refer to Figure 8 for understanding. The electronic atomization device 100 also includes a puncturable first film member 111 and a second film member 112. The first film member 111 is disposed in the first through hole 109 and is located near the other end of the first through hole 109 or the first receiving chamber 108. The first film member 111 is used to seal the first through hole 109. The second film member 112 is disposed in the second through hole 110 and is located near the other end of the second through hole 110 or the first receiving chamber 108. The second film member 112 is used to seal the second through hole 110.

[0111] The liquid storage component 200 further includes a puncturable third film member 205 and a fourth film member 206. The third film member 205 is disposed in the third through hole 203 and near the other end of the third through hole 203, and is used to seal the third through hole 203. The fourth film member 206 is disposed in the fourth through hole 204 and near the other end of the fourth through hole 204, and is used to seal the fourth through hole 204.

[0112] The first film member 111, the second film member 112, the third film member 205, and the fourth film member 206 are all made of a flexible material, such as silicone. The thickness of the film member should be determined based on the considerations of sealing the through-holes to prevent leakage of the liquid matrix and making it relatively easy for the user to puncture the film.

[0113] In actual use, the liquid storage component 200 can be connected to the electronic atomization device 100 at any time before the first liquid matrix in the first liquid storage chamber 103 is consumed. Before the liquid storage component 200 is connected to the electronic atomization device 100, that is, before the second housing component 201 is connected to the first housing component 101, a separate piercing member can be used to pierce the first film component 111, the second film component 112, the third film component 205, and the fourth film component 206, and then the second housing component 201 can be connected to the first housing component 101.

[0114] In a preferred embodiment, as shown in FIG8 , the electronic atomization device 100 further includes a first piercing member 113 and a second piercing member 114. One end of the first piercing member 113 extends into the first through hole 109 and is disposed near the first film member 111. The other end of the first piercing member 113 can be fixedly connected to a component within the first housing assembly 101. One end of the first piercing member 113 is in the shape of a needle or a knife. One end of the second piercing member 114 extends into the second through hole 110 and is disposed near the second film member 112. The other end of the second piercing member 114 can be fixedly connected to a component within the first housing assembly 101. One end of the second piercing member 114 is in the shape of a needle or a knife. In this way, when the other end of the third through hole 203 extends into the first through hole 109, the other end of the third through hole 203 squeezes the first film member 111 to deform it toward one end of the first piercing member 113. When it continues to extend, the first piercing member 113 can pierce the first film member 111 and the third film member 205 in sequence; similarly, when the other end of the fourth through hole 204 extends into the second through hole 110, the other end of the fourth through hole 204 squeezes the second film member 112 to deform it toward one end of the second piercing member 114. When it continues to extend, the second piercing member 114 can pierce the second film member 112 and the fourth film member 206 in sequence.

[0115] In further implementation, as shown in FIG8 , a first sealing member is provided between the first through hole 109 and the third through hole 203 to seal the gap therebetween; and a second sealing member is provided between the second through hole 110 and the fourth through hole 204 to seal the gap therebetween. Both the first sealing member and the second sealing member are made of a flexible material, such as silicone.

[0116] Specifically, the first seal comprises a second seal 115 and a first seal 207. The second seal 115 is disposed on the inner surface of the wall defining the first through-hole 109, while the first seal 207 is disposed on the outer surface of the wall defining the third through-hole 203. In a preferred embodiment, the second seal 115 extends circumferentially along the inner surface of the wall defining the first through-hole 109, for example, in the form of a ring. The first seal 207 extends circumferentially along the outer surface of the wall defining the third through-hole 203, for example, in the form of a ring. When the wall defining the third through-hole 203 extends into the first through-hole 109, the first seal 207 and the second seal 115 squeeze each other, forming a good seal. Specifically, the first seal 207 is sandwiched between the second seal 115 and the outer surface of the wall defining the third through-hole 203. For example, the ring-shaped first seal 207 is at least partially contained within the ring-shaped second seal 115. Similarly, the second seal includes a fourth seal 116 and a third seal 208. The fourth seal 116 is arranged on the inner surface of the wall defining the second through hole 110, and the third seal 208 is arranged on the outer surface of the wall defining the fourth through hole 204. When the wall defining the fourth through hole 204 extends into the second through hole 110, the third seal 208 and the fourth seal 116 squeeze each other to form a good sealing effect.

[0117] It should be noted that the first seal 207 and the third film 205 can be formed integrally or separately. Similarly, the third seal 208 and the fourth film 206, the second seal 115 and the first film 111, and the fourth seal 116 and the second film 112 can also be arranged in the same manner.

[0118] It should be noted that the above-mentioned electronic atomization device 100 and liquid storage component 200 are independent of each other. Before the electronic atomization device 100 and the liquid storage component 200 are not connected (that is, before the second shell component 201 is connected to the first shell component 101), the electronic atomization device 100 can be used alone and sucked, and the atomization component 104 only atomizes the first liquid matrix. After the electronic atomization device 100 and the liquid storage component 200 are connected (that is, after the second shell component 201 is connected to the first shell component 101), the atomization component 104 can atomize both the first liquid matrix and the second liquid matrix. The combination of the electronic atomization device 100 and the liquid storage component 200 can also be collectively referred to as an electronic atomization device.

[0119] It should also be noted that there can be multiple liquid storage components 200.

[0120] The following describes an electronic atomization device provided by another embodiment of the present application in conjunction with Figures 9 to 14. In the examples of Figures 9 to 14, reference can be made to the aforementioned parts for the same reference numerals as those in Figures 1 to 8.

[0121] Unlike the examples in Figures 1-8 , in the examples in Figures 9-14 , the electronic atomization device cannot be used or inhaled before the second housing assembly 201 is connected to the first housing assembly 101. That is, the electronic atomization device can only be used and inhaled after the second housing assembly 201 is connected to the first housing assembly 101. At this time, the atomization assembly 104 can atomize both the first liquid matrix and the second liquid matrix.

[0122] Different from the example of FIG. 1 to FIG. 8 , in the example of FIG. 9 to FIG. 14 , the suction nozzle 102 ′ is provided on the second housing assembly 201 .

[0123] In the examples of FIG. 1 to FIG. 8 , no air flow channel is provided in the second housing assembly 201 .

[0124] Unlike the examples in Figures 1-8 , in the examples in Figures 9-14 , the airflow channel includes a first airflow channel 105a and a second airflow channel 105b. The first airflow channel 105a is disposed in the first housing assembly 101, and the second airflow channel 105b is disposed in the second housing assembly 201. When the second housing assembly 201 is connected to the first housing assembly 101, the first airflow channel 105a and the second airflow channel 105b communicate to transmit the aerosol generated by the atomizer assembly 104. The first liquid storage chamber 103 is disposed around at least a portion of the first airflow channel 105a, and the second liquid storage chamber 202 is disposed around at least a portion of the second airflow channel 105b. The lower end of the first air flow channel 105a is connected to the air inlet (for example, it can be set on the bottom wall of the first shell assembly 101), and the upper end of the first air flow channel 105a is connected to the lower end of the second air flow channel 105b. For example, the upper end of the first air flow channel 105a can extend into the second air flow channel 105b, and the upper end of the second air flow channel 105b is connected to the suction nozzle 102', that is, it is connected to the air outlet.

[0125] Unlike the examples in Figures 1-8 , in the examples in Figures 9-14 , when the second housing assembly 201 is connected to the first housing assembly 101, the first liquid storage chamber 103 and the second liquid storage chamber 202 are arranged sequentially approximately along the length of the electronic atomization device. The first liquid storage chamber 103 is located near the bottom of the electronic atomization device, while the second liquid storage chamber 202 is located near the top of the electronic atomization device.

[0126] Different from the examples in Figures 1 to 8, in the examples in Figures 9 to 14, one end of the first through hole 109 is connected to the liquid matrix portion below the liquid surface of the first liquid storage chamber 103, and the other end of the first through hole 109 protrudes from the top wall of the first shell assembly 101; one end of the second through hole 110 is connected to the air portion above the liquid surface of the first liquid storage chamber 103, and the other end of the second through hole 110 protrudes from the top wall of the first shell assembly 101.

[0127] Unlike the example of Figures 1-8 , in the example of Figures 9-14 , one end of the third through hole 203 communicates with the liquid matrix portion below the liquid level of the second liquid storage chamber 202, while the other end of the third through hole 203 protrudes from the bottom wall of the second housing assembly 201. One end of the fourth through hole 204 passes through the second liquid storage chamber 202 and communicates with the air portion above the liquid level of the second liquid storage chamber 202, while the other end of the fourth through hole 204 extends to the bottom wall of the second housing assembly 201.

[0128] Different from the examples in Figures 1 to 8, in the examples in Figures 9 to 14, when the second shell assembly 201 is connected to the first shell assembly 101, the other end of the third through hole 203 extends into the first through hole 109, thereby allowing the liquid matrix portion below the liquid surface of the first liquid storage chamber 103 to communicate with the liquid matrix portion below the liquid surface of the second liquid storage chamber 202; the other end of the second through hole 110 extends into the fourth through hole 204, thereby allowing the air portion above the liquid surface of the first liquid storage chamber 103 to communicate with the air portion above the liquid surface of the second liquid storage chamber 202.

[0129] Unlike the examples in Figures 1-8 , in the examples in Figures 9-14 , there are two second through holes 110 and two fourth through holes 204, both spaced apart along the thickness of the electronic atomizer. Multiple air passages can better balance the air pressure in the first liquid storage chamber 103 and the second liquid storage chamber 202.

[0130] Similar to the examples shown in Figures 1 to 8 , the first housing assembly 101 further includes a first receiving cavity 108 for receiving a portion of the second housing assembly 201. It is understood that in other examples, it is also feasible to provide the second housing assembly 201 with a second receiving cavity for receiving or accommodating at least a portion of the first housing assembly 101.

[0131] It should be noted that other features shown in the examples of Figures 1 to 8 are also applicable to the examples of Figures 9 to 14. For example, the film member, puncture member, sealing member, etc. shown in the examples of Figures 1 to 8 are also applicable.

[0132] The electronic atomization device provided by another embodiment of the present application is described below in conjunction with Figure 15. In the example of Figure 15, the same reference numerals as those in Figures 1 to 8 can be referred to the aforementioned parts.

[0133] Unlike the example shown in Figures 1-8 , in the example shown in Figure 15 , when the second housing assembly 201 is connected to the first housing assembly 101, the second liquid storage chamber 202 surrounds at least a portion of the first liquid storage chamber 103. One end of the air channel C communicates with the air portion above the liquid level in the first liquid storage chamber 103, while the other end of the air channel C communicates with the air portion above the liquid level in the second liquid storage chamber 202. One end of the liquid channel D communicates with the liquid matrix portion below the liquid level in the first liquid storage chamber 103, while the other end of the liquid channel D communicates with the liquid matrix portion below the liquid level in the second liquid storage chamber 202.

[0134] The following describes an electronic atomization device according to another embodiment of the present application in conjunction with Figures 16 to 19. In the examples of Figures 16 to 19, reference can be made to the aforementioned parts for the same reference numerals as those in Figures 1 to 8.

[0135] Different from the examples in Figures 1 to 8, in the examples in Figures 16 to 19, a first liquid storage chamber 103, an atomizing assembly 104 and an air flow channel 105 are provided in the first shell assembly 101 of the electronic atomizing device, and the air flow channel 105 transmits the aerosol generated by the atomizing assembly 104 to the mouthpiece (the upper end of the first shell assembly 101) so as to be inhaled by the user. However, components such as circuits, batteries, and puff detectors are not provided in the first shell assembly 101. Therefore, the electronic atomizing device shown in Figures 16 to 19 can also be referred to as an atomizer, a cigarette cartridge, etc. When in use, the electronic atomizing device shown in Figures 16 to 19 can be used in combination with a power supply assembly (or a cigarette rod), wherein components such as circuits, batteries, and a puff detector are provided in the power supply assembly (or cigarette rod).

[0136] Different from the examples in Figures 1 to 8, the examples in Figures 16 to 19 further include a first connecting member 300, one end of the first connecting member 300 is detachably connected to the first shell assembly 101, and the other end of the first connecting member 300 is detachably connected to the second shell assembly 201; when the first connecting member 300 is connected to the first shell assembly 101 and the second shell assembly 201, the first liquid storage chamber 103 and the second liquid storage chamber 202 can be connected.

[0137] Specifically, the first connector 300 can be configured as a tubular structure, and its two ends can be needle-shaped or knife-shaped structures. The length of the first connector 300 is not limited and can be appropriately made longer. One end of the first connector 300 can be extended into the first through hole 109, thereby communicating with the first through hole 109, that is, communicating with the liquid matrix portion below the liquid level of the first liquid storage chamber 103; the other end of the first connector 300 can be extended into the third through hole 203, thereby communicating with the third through hole 203, that is, communicating with the liquid matrix portion below the liquid level of the second liquid storage chamber 202. The hollow portion inside the first connector 300 also defines a partial liquid channel (first channel).

[0138] It is understandable that, in other examples, it is also feasible that one end of the first through hole 109 extends into the first connecting member 300 (i.e., one end of the first connecting member 300 is arranged around at least a portion of the first through hole 109), and one end of the third through hole 203 extends into the first connecting member 300 (i.e., the other end of the first connecting member 300 is arranged around at least a portion of the third through hole 203).

[0139] It should be noted that in the examples of Figures 16-19, only the first through hole 109 and the third through hole 203 are provided. In other examples, similar to the examples of Figures 1-8, a second through hole 110 and a fourth through hole 204 may also be provided, and a second connector may be included. One end of the second connector may extend into the second through hole 110, thereby communicating with the second through hole 110, that is, communicating with the air portion above the liquid level of the first liquid storage chamber 103; the other end of the second connector may extend into the fourth through hole 204, thereby communicating with the fourth through hole 204, that is, communicating with the air portion above the liquid level of the second liquid storage chamber 202. The hollow portion inside the second connector also defines a partial air channel (second channel).

[0140] In other examples, it is also feasible that one end of the second through hole 110 extends into the second connector (i.e., one end of the second connector is arranged around at least a portion of the second through hole 110), and one end of the fourth through hole 204 extends into the second connector (i.e., the other end of the second connector is arranged around at least a portion of the fourth through hole 204).

[0141] Similar to the example of Figures 1 to 8 , the example of Figures 16 to 19 further includes a first partial sealing member 207 and a third film member 205, and a second partial sealing member 115 and a first film member 111. During use, the third film member 205 and the first film member 111 can be pierced by the first connector 300, forming a seal between the first partial sealing member 207 (or the second partial sealing member 115) and the first connector 300.

[0142] Unlike the example of Figures 1-8 , the example of Figures 16-19 further includes a stopper 209, which is disposed within the second housing assembly 201. The stopper 209 may be a baffle disposed within the second housing assembly 201. Thus, when the other end of the first connector 300 extends into the third through-hole 203, the stopper 209 can limit the other end of the first connector 300. This, on the one hand, prevents the first connector 300 from being fully inserted into the second housing assembly 201, and on the other hand, allows the user to confirm that the insertion is in place. It is understood that the stopper may also be disposed within the first housing assembly 101, or within both the first housing assembly 101 and the second housing assembly 201.

[0143] It should be noted that the first connecting member 300 and its associated features in the examples of Figures 16 to 19 are also applicable to the examples of Figures 1 to 8, or the examples of Figures 9 to 14.

[0144] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of this application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to be additional limitations on the content of this application. The purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and comprehensive. In addition, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of this application; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
