All of the above contents are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of electronic atomization technology, and in particular to a liquid storage component and an electronic atomization device. Background Art

[0004] An electronic atomization device is an electronic product that generates aerosols for users to inhale by atomizing liquid matrices. It generally consists of two parts: an atomizer and a power supply assembly. The atomizer stores the liquid matrix and is equipped with an atomization assembly for atomizing the liquid matrix. The power supply assembly includes a battery and a circuit board.

[0005] Existing electronic atomization devices, limited by various factors such as cost and regulations, typically store a relatively small amount of liquid matrix within the atomizer. When the liquid matrix is ​​depleted, the atomizer can be refilled, replaced, or simply discarded. These methods, while inconvenient for users and reducing their experience, also increase user costs.

[0006] Utility Model Content

[0007] The present application aims to provide a liquid storage component and an electronic atomization device to avoid the problem that existing electronic atomization devices bring inconvenience to users and increase users' usage costs.

[0008] On one hand, the present application provides an electronic atomization device, comprising:

[0009] a first liquid storage chamber, for storing a first liquid matrix;

[0010] a second liquid storage chamber, for storing a second liquid matrix;

[0011] a nebulizing assembly for atomizing a liquid matrix to generate an aerosol;

[0012] a first channel, one end of which is in communication with the first liquid storage chamber and the other end of which is in communication with the second liquid storage chamber, thereby providing a fluid path between the first liquid storage chamber and the second liquid storage chamber for allowing the first liquid matrix and / or the second liquid matrix to flow;

[0013] The switch is configured to selectively open or close the first channel based on a user's operation.

[0014] In one example, the switch element includes an electrically operated switch element to selectively open or close the first channel under electrical operation.

[0015] In one example, the switch element includes a manually operated switch element to selectively open or close the first channel under manual operation.

[0016] In one example, the switch element includes an operating portion that is at least partially exposed on the housing of the electronic atomization device, and the operating portion is configured to accept manual operation by a user to open or close the first channel.

[0017] In one example, the operating portion is configured to be movable relative to the housing of the electronic atomization device, and the movable range includes a first position for opening the first channel and a second position for closing the first channel.

[0018] In one example, a portion of the operating portion is located in the first channel, and a through hole is provided on the portion of the operating portion;

[0019] When the operating portion moves to the first position, the through hole is communicated with the first channel, thereby opening the first channel; when the operating portion moves to the second position, the through hole is misaligned with the first channel, thereby closing the first channel.

[0020] In one example, a sealing member is further included, wherein the sealing member is at least partially disposed between the operating portion and the first channel.

[0021] In one example, the operating portion includes a contact portion and a movable portion connected to the contact portion;

[0022] The contact portion is configured to receive an operation from a user to drive the movable portion to move relative to the housing of the electronic atomization device;

[0023] When the contact portion and the movable portion move together to the first position, the movable portion opens the first channel; when the contact portion and the movable portion move together to the second position, the movable portion at least partially extends into the first channel, thereby closing the first channel.

[0024] In one example, a portion of the switch element is configured to extend into the first channel and be relatively slidable, thereby pumping the second liquid matrix from the second liquid storage chamber in the first channel into the first liquid storage chamber.

[0025] In one example, a second channel is further included, one end of the second channel is connected to the first liquid storage chamber, and the other end of the second channel is connected to the second liquid storage chamber, which is used to provide an air exchange path between the first liquid storage chamber and the second liquid storage chamber to enable the air above the liquid levels of the two to communicate with each other.

[0026] In one example, the invention further includes a first housing component and a second housing component independent of the first housing component;

[0027] The first liquid storage chamber is formed in the first shell component, and the atomizing component is arranged in the first shell component; the second liquid storage chamber is formed in the second shell component.

[0028] The first housing component is configured to be connectable with the second housing component and to simultaneously establish the first channel between the two.

[0029] In one example, the switch element is disposed on the second housing component or the first housing component.

[0030] In one example, the volume of the first liquid storage chamber is smaller than the volume of the second liquid storage chamber.

[0031] In one example, the first liquid storage chamber stores a first liquid matrix with a capacity of 0.1 ml to 2 ml, and the second liquid storage chamber stores a second liquid matrix with a capacity of 2 ml to 10 ml.

[0032] Another aspect of the present application provides an electronic atomization device, comprising:

[0033] a first housing component, wherein a first liquid storage cavity for storing a first liquid matrix is ​​formed in the first housing component;

[0034] an atomizing assembly disposed in the first housing assembly; the atomizing assembly is used to atomize the first liquid matrix to generate an aerosol;

[0035] a second housing assembly, independent of the first housing assembly, wherein a second liquid storage chamber for storing a second liquid matrix is ​​formed in the second housing assembly; the second housing assembly is configured to be connectable to the first housing assembly in a separate state and to establish a first passage therebetween, wherein the first passage connects the first liquid storage chamber and the second liquid storage chamber, thereby providing a fluid path between the first liquid storage chamber and the second liquid storage chamber for allowing the first liquid matrix and / or the second liquid matrix to flow;

[0036] The switch is configured to selectively open or close the first channel based on user operation.

[0037] In another aspect, the present application further provides a liquid storage component, comprising:

[0038] a second housing component, wherein a second liquid storage cavity for storing a second liquid matrix is ​​formed in the second housing component;

[0039] a second through hole, disposed on the second housing component and in fluid communication with the second liquid storage chamber so as to guide the second liquid matrix to be discharged out of the second liquid storage chamber;

[0040] The switch member is configured to selectively open or close the second through hole based on a user operation.

[0041] The above liquid storage component and electronic atomization device can selectively connect or disconnect the first liquid storage chamber and the second liquid storage chamber through a switch component, which on the one hand increases the capacity of the liquid matrix, and on the other hand reduces the user's usage cost and improves the user's usage experience.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] As shown in Figures 1 to 4, the electronic atomization device 100 provided in one embodiment of the present application includes a shell assembly 101 (first shell assembly). The 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 shell assembly 101 can also be formed as one piece.

[0078] The top of the housing assembly 101 is provided with a nozzle 102. The nozzle 102 and the housing assembly 101 can be formed integrally or separately. The nozzle 102 is used for the user to inhale the aerosol generated by atomization.

[0079] The housing assembly 101 is formed with a liquid storage chamber 103 (first liquid storage chamber) that is used to store the first liquid matrix. The first liquid matrix can be the liquid that comprises the tobacco-containing material that contains volatile tobacco flavor components, or can be the liquid that comprises non-tobacco substances. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture. Spices 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 the material that is mixed with at least a 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 as glycerol and propylene glycol.

[0080] Typically, the volume of the first liquid matrix stored in the 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 liquid storage chamber 103 is slightly larger than the volume of the first liquid matrix stored. Thus, after the first liquid matrix is ​​stored in the 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.

[0081] An atomizing assembly 104 is also provided in the housing assembly 101 , and the atomizing assembly 104 is used to atomize the liquid matrix to generate an aerosol.

[0082] In one example, the atomizing assembly 104 includes a liquid delivery unit and a heating element.

[0083] The liquid transfer unit can transfer the liquid matrix in the 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, porous glass, etc. The liquid transfer unit can be configured as a tubular structure, a plate structure, or other regular or irregular shapes.

[0084] 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.

[0085] 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.

[0086] An air flow channel 105 is further provided in the housing assembly 101 to transmit the aerosol generated by the atomizing assembly 104 to the mouthpiece 102 for inhalation by the user.

[0087] 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 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 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 liquid storage chamber 103 and the atomization assembly 104, so that the liquid matrix in the liquid storage chamber 103 can be transferred to the atomization assembly 104 and atomized.

[0088] The housing assembly 101 also includes a circuit 106 that 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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 housing 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.

[0093] 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, liquid storage chamber 103, and atomization assembly 104 are located in the atomizer. This is also feasible.

[0094] Referring again to Figures 1-4, the liquid storage component 200 provided in one embodiment of the present application includes a housing assembly 201 (second housing assembly), which is composed of a main body 201a and a top cover 201b. The main body 201a is a barrel-shaped structure, and the top cover 201b is arranged on the top of the main body 201a.

[0095] The housing assembly 201 is formed with a liquid storage chamber 202 (second liquid storage chamber) that is used to store the second liquid matrix. 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 components, can also be the liquid that comprises non-tobacco substances. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring or vitamin mixture. Spices can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this. Flavoring can comprise the composition that can provide multiple fragrance or local flavor to the user. Vitamin mixture can be the material that is mixed with at least a 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.

[0096] It should be noted that the properties of the second liquid matrix may be different from or the same as those of the first liquid matrix. For example, the second liquid matrix may have different components than the first liquid matrix, or the second liquid matrix may have different concentrations than the first liquid matrix. The second liquid matrix may be part of a certain formulation, while the first liquid matrix may be another part of the same formulation.

[0097] The volume of liquid storage chamber 202 is larger than that of liquid storage chamber 103. Generally, the volume of the second liquid matrix stored in 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 liquid storage chamber 202 is slightly larger than the volume of the second liquid matrix stored. Thus, after the second liquid matrix is ​​stored in 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.

[0098] 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 housing assembly 201 is detachably connected to the housing assembly 101. In another example, the liquid storage component 200 is not detachable after being connected to the electronic atomization device 100.

[0099] The shell assembly 101 is provided with a receiving cavity 108 for receiving or accommodating at least part of the shell assembly 201. Specifically, the shape of the receiving cavity 108 is adapted to the shape of the shell assembly 201. The receiving cavity 108 is a notch groove that passes through part of the left side wall and part of the top wall of the shell assembly 101. The shell assembly 201 can be assembled to or retained on the shell assembly 101 from the left side of the shell assembly 101. The inner wall of the receiving cavity 108 is provided with a snap connector 108a, and the outer wall of the shell assembly 201 is provided with a snap connector 201c. The snap connection between the shell assembly 201 and the shell assembly 101 is achieved by the cooperation between the snap connector 108a and the snap connector 201c. After the shell assembly 201 is connected to the shell assembly 101, they jointly define the outer shell of the electronic atomization device 100. It can be understood that the connection method between the shell assembly 201 and the shell assembly 101 is not limited to the above situation.

[0100] When the housing assembly 201 is connected to the housing assembly 101, the liquid storage chamber 103 and the liquid storage chamber 202 are arranged in sequence substantially along the width direction of the electronic atomization device 100. The liquid storage chamber 103 is arranged near the right end of the electronic atomization device 100, while the liquid storage chamber 202 is arranged near the left end of the electronic atomization device 100.

[0101] When the housing assembly 201 is connected to the housing assembly 101, the air portion above the liquid surface of the liquid storage chamber 103 is connected to the air portion above the liquid surface of the liquid storage chamber 202, and the liquid matrix portion below the liquid surface of the liquid storage chamber 103 is connected to the liquid matrix portion below the liquid surface of the liquid storage chamber 202.

[0102] Specifically, as shown in conjunction with Figures 6 and 7 , housing assembly 101 further includes spaced-apart through-holes 109 and 110. One end of through-hole 109 communicates with the liquid matrix portion below the liquid level of liquid storage chamber 103, while the other end of through-hole 109 extends to the right side of the inner wall of receiving chamber 108. Through-hole 110 is located above through-hole 109, with one end communicating with the air portion above the liquid level of liquid storage chamber 103 and the other end extending to the right side of the inner wall of receiving chamber 108.

[0103] The housing assembly 201 also includes spaced-apart through-holes 203 (second through-holes) and 204. One end of through-hole 203 is in fluid communication with the portion of the liquid matrix below the liquid level in the liquid storage chamber 202, thereby guiding the second liquid matrix out of the liquid storage chamber 202. The other end of through-hole 203 protrudes from the outer surface of the right side of the housing assembly 201. Through-hole 204 is located above through-hole 203. One end of through-hole 204 is in fluid communication with the air portion above the liquid level in the liquid storage chamber 202, and the other end of through-hole 204 protrudes from the outer surface of the right side of the housing assembly 201.

[0104] When the housing assembly 201 is connected to the housing assembly 101, at least a portion of the wall defining the through hole 203 extends into the through hole 109, thereby allowing the liquid matrix portion below the liquid surface of the liquid storage chamber 103 to communicate with the liquid matrix portion below the liquid surface of the liquid storage chamber 202; at least a portion of the wall defining the through hole 204 extends into the through hole 110, thereby allowing the air portion above the liquid surface of the liquid storage chamber 103 to communicate with the air portion above the liquid surface of the liquid storage chamber 202.

[0105] In this case, through-hole 203 and / or through-hole 109 define a liquid channel (first channel), thereby providing a fluid path between liquid storage chamber 103 and liquid storage chamber 202 for allowing the first liquid matrix and / or the second liquid matrix to flow. One end of the liquid channel communicates with the portion of the liquid matrix below the liquid surface of liquid storage chamber 103, while the other end of the liquid channel communicates with the portion of the liquid matrix below the liquid surface of liquid storage chamber 202. Through-hole 204 and / or through-hole 110 define an air channel (second channel), thereby providing an air exchange path between liquid storage chamber 103 and liquid storage chamber 202 for allowing air above the liquid surfaces of the two chambers to communicate with each other. One end of the air channel communicates with the air above the liquid surface of liquid storage chamber 103, while the other end of the air channel communicates with the air above the liquid surface of liquid storage chamber 202. The air channel can balance the air pressure of the liquid storage chamber 103 and the liquid storage chamber 202, so that the second liquid matrix stored in the liquid storage chamber 202 can flow smoothly through the liquid channel to the liquid storage chamber 103, and the consumed liquid matrix can be replenished to the liquid storage chamber 103 in time.

[0106] In further implementation, please refer to FIG4 for understanding. The through hole 203 is provided near the bottom wall of the housing assembly 201. The bottom wall of the housing assembly 201 is inclined toward the through hole 203, or the bottom wall of the housing assembly 201 has an inclined surface 201a1 inclined toward the through hole 203. In this way, the liquid matrix in the liquid storage chamber 202 can flow into the liquid storage chamber 103 better, rather than being accumulated in the liquid storage chamber 202, thereby avoiding waste of the liquid matrix.

[0107] In further implementation, please refer to Figure 8 for understanding. The electronic atomization device 100 also includes a puncturable film member 111 and a film member 112. The film member 111 is disposed in the through hole 109 and is close to the other end of the through hole 109 or the receiving cavity 108. The film member 111 is used to close the through hole 109. The film member 112 is disposed in the through hole 110 and is close to the other end of the through hole 110 or the receiving cavity 108. The film member 112 is used to close the through hole 110.

[0108] Liquid storage component 200 further includes a puncturable film 205 and a film 206. Film 205 is disposed in through-hole 203 and near the other end of through-hole 203, and is used to seal through-hole 203. Film 206 is disposed in through-hole 204 and near the other end of through-hole 204, and is used to seal through-hole 204.

[0109] Films 111, 112, 205, and 206 are all made of a flexible material, such as silicone. The thickness of the films should be determined based on the need to seal the through-holes to prevent leakage of the liquid matrix and to ensure ease of puncture by the user.

[0110] 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 liquid storage chamber 103 is consumed. Before the liquid storage component 200 is connected to the electronic atomization device 100, that is, before the housing assembly 201 is connected to the housing assembly 101, a separate piercing member can be used to pierce the film member 111, the film member 112, the film member 205, and the film member 206, and then the housing assembly 201 is connected to the housing assembly 101.

[0111] In a preferred embodiment, as shown in FIG8 , the electronic atomization device 100 further includes a piercing member 113 and a piercing member 114. One end of the piercing member 113 extends into the through-hole 109 and is disposed adjacent to the film member 111. The other end of the piercing member 113 can be fixedly connected to a component within the housing assembly 101. One end of the piercing member 113 has a needle-like or blade-like structure. One end of the piercing member 114 extends into the through-hole 110 and is disposed adjacent to the film member 112. The other end of the piercing member 114 can be fixedly connected to a component within the housing assembly 101. One end of the piercing member 114 has a needle-like or blade-like structure. In this way, when the other end of the through hole 203 extends into the through hole 109, the other end of the through hole 203 squeezes the film member 111 to deform it toward one end of the piercing member 113. When it continues to extend, the piercing member 113 can pierce the film member 111 and the film member 205 in sequence; similarly, when the other end of the through hole 204 extends into the through hole 110, the other end of the through hole 204 squeezes the film member 112 to deform it toward one end of the piercing member 114. When it continues to extend, the piercing member 114 can pierce the film member 112 and the film member 206 in sequence.

[0112] In further implementation, as shown in FIG8 , a first sealing member is provided between through-hole 109 and through-hole 203 to seal the gap therebetween; and a second sealing member is provided between through-hole 110 and 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.

[0113] Specifically, the first seal includes a seal 115 and a seal 207. Seal 115 is disposed on the inner surface of the wall defining through-hole 109, and seal 207 is disposed on the outer surface of the wall defining through-hole 203. In a preferred embodiment, seal 115 extends circumferentially along the inner surface of the wall defining through-hole 109, for example, in the form of a ring-shaped seal; and seal 207 extends circumferentially along the outer surface of the wall defining through-hole 203, for example, in the form of a ring-shaped seal. When the wall defining through-hole 203 extends into through-hole 109, seal 207 and seal 115 squeeze each other, thereby forming a good seal. Specifically, seal 207 is sandwiched between seal 115 and the outer surface of the wall defining through-hole 203, for example, the ring-shaped seal 207 is at least partially contained within the ring-shaped seal 115. Similarly, the second seal includes a seal 116 and a seal 208. The seal 116 is arranged on the inner surface of the wall defining the through hole 110, and the seal 208 is arranged on the outer surface of the wall defining the through hole 204. When the wall defining the through hole 204 extends into the through hole 110, the seal 208 and the seal 116 squeeze each other to form a good sealing effect.

[0114] It should be noted that the sealing member 207 and the film member 205 can be formed integrally or separately. Similarly, the sealing member 208 and the film member 206, the sealing member 115 and the film member 111, and the sealing member 116 and the film member 112 can also be arranged in the same manner.

[0115] 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 shell component 201 is not connected to the 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 shell component 201 is connected to the 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.

[0116] It should also be noted that there can be multiple liquid storage components 200.

[0117] The following describes an electronic atomization device and a liquid storage component 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 in Figures 1 to 8.

[0118] Unlike the examples of Figures 1-8 , in the examples of Figures 9-14 , the electronic atomization device cannot be used or inhaled before the housing assembly 201 is connected to the housing assembly 101. That is, the electronic atomization device can only be used and inhaled after the housing assembly 201 is connected to the housing assembly 101. At this time, the atomization assembly 104 can atomize both the first liquid matrix and the second liquid matrix.

[0119] 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 housing assembly 201 .

[0120] In the examples of FIG. 1 to FIG. 8 , no air flow channel is provided in the housing assembly 201 .

[0121] Unlike the examples of Figures 1-8 , in the examples of Figures 9-14 , the airflow channel 105 includes a first airflow channel 105a and a second airflow channel 105b. The first airflow channel 105a is disposed in the housing assembly 101, and the second airflow channel 105b is disposed in the housing assembly 201. When the housing assembly 201 is connected to the housing assembly 101, the first airflow channel 105a and the second airflow channel 105b are in communication to transmit the aerosol generated by the atomization assembly 104. The liquid storage chamber 103 is disposed around at least a portion of the first airflow channel 105a, and the 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 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.

[0122] Unlike the examples in Figures 1-8 , in the examples in Figures 9-14 , when the housing assembly 201 is connected to the housing assembly 101, the liquid storage chamber 103 and the liquid storage chamber 202 are arranged sequentially along the length of the electronic atomization device. The liquid storage chamber 103 is arranged near the bottom of the electronic atomization device, while the liquid storage chamber 202 is arranged near the top of the electronic atomization device.

[0123] Different from the examples in Figures 1 to 8, in the examples in Figures 9 to 14, one end of the through hole 109 is connected to the liquid matrix portion below the liquid surface of the liquid storage chamber 103, and the other end of the through hole 109 protrudes from the top wall of the shell assembly 101; one end of the through hole 110 is connected to the air portion above the liquid surface of the liquid storage chamber 103, and the other end of the through hole 110 protrudes from the top wall of the shell assembly 101.

[0124] Unlike the example of Figures 1-8 , in the example of Figures 9-14 , one end of through-hole 203 communicates with the liquid matrix portion below the liquid level of liquid storage chamber 202, while the other end of through-hole 203 protrudes from the bottom wall of housing assembly 201. One end of through-hole 204 passes through liquid storage chamber 202 and communicates with the air portion above the liquid level of liquid storage chamber 202, while the other end of through-hole 204 extends to the bottom wall of housing assembly 201.

[0125] Different from the examples in Figures 1 to 8, in the examples in Figures 9 to 14, when the housing assembly 201 is connected to the housing assembly 101, the other end of the through hole 203 extends into the through hole 109, thereby allowing the liquid matrix portion below the liquid surface of the liquid storage chamber 103 to communicate with the liquid matrix portion below the liquid surface of the liquid storage chamber 202; the other end of the through hole 110 extends into the through hole 204, thereby allowing the air portion above the liquid surface of the liquid storage chamber 103 to communicate with the air portion above the liquid surface of the liquid storage chamber 202.

[0126] Unlike the examples in Figures 1-8 , in the examples in Figures 9-14 , there are two through holes 110 and two through holes 204, both spaced apart along the thickness of the electronic atomizer. Multiple air passages can better balance the air pressure in the liquid storage chamber 103 and the liquid storage chamber 202.

[0127] 1 to 8 , the housing assembly 101 further includes a receiving cavity 108 for receiving a portion of the housing assembly 201. It is understood that in other examples, the housing assembly 201 may include a receiving cavity for receiving or accommodating at least a portion of the housing assembly 101.

[0128] 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.

[0129] The electronic atomization device and liquid storage component provided by another embodiment of the present application are described below in conjunction with Figure 15. In the example of Figure 15, the parts with the same numbers as Figures 1 to 8 can refer to the aforementioned parts.

[0130] Unlike the example shown in Figures 1-8 , in the example shown in Figure 15 , when housing assembly 201 is connected to housing assembly 101, liquid storage chamber 202 surrounds at least a portion of liquid storage chamber 103. One end of air channel C communicates with the air portion above the liquid level in liquid storage chamber 103, while the other end of air channel C communicates with the air portion above the liquid level in liquid storage chamber 202. One end of liquid channel D communicates with the liquid matrix portion below the liquid level in liquid storage chamber 103, while the other end of liquid channel D communicates with the liquid matrix portion below the liquid level in liquid storage chamber 202.

[0131] The electronic atomization device provided in another embodiment of the present application is described below in conjunction with Figures 16 to 19. In the examples of Figures 16 to 19, the same reference numerals as those in Figures 1 to 8 can be referred to the aforementioned parts.

[0132] Different from the examples in Figures 1 to 8, in the examples in Figures 16 to 19, a liquid storage chamber 103, an atomizing assembly 104 and an air flow channel 105 are provided in the 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 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 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 the power supply assembly (or cigarette rod) is provided with components such as circuits, batteries, and a puff detector.

[0133] Different from the examples in Figures 1 to 8, the examples in Figures 16 to 19 further include a connecting member 300, one end of which is detachably connected to the shell assembly 101, and the other end of the connecting member 300 is detachably connected to the shell assembly 201; when the connecting member 300 is connected to the shell assembly 101 and the shell assembly 201, the liquid storage chamber 103 can be connected to the liquid storage chamber 202.

[0134] Specifically, the connector 300 can be constructed into a tubular structure, the hollow portion of which forms a liquid transmission channel, and its two ends can be needle-shaped or knife-shaped structures. The length of the connector 300 is not limited and can be appropriately made longer. One end of the connector 300 can be extended into the through hole 109, thereby communicating with the through hole 109, that is, communicating with the liquid matrix portion below the liquid surface of the liquid storage chamber 103; the other end of the connector 300 can be extended into the through hole 203, thereby communicating with the through hole 203, that is, communicating with the liquid matrix portion below the liquid surface of the liquid storage chamber 202. The hollow portion inside the connector 300 also defines a partial liquid channel (first channel).

[0135] It is understandable that in other examples, it is also feasible that one end of the through hole 109 extends into the connector 300 (i.e., one end of the connector 300 is arranged around at least part of the through hole 109), and one end of the through hole 203 extends into the connector 300 (i.e., the other end of the connector 300 is arranged around at least part of the through hole 203).

[0136] It should be noted that, in the examples of Figures 16 to 19 , only through-hole 109 and through-hole 203 are provided. In other examples, similar to the examples of Figures 1 to 8 , through-hole 110 and through-hole 204 may also be provided.

[0137] Similar to the example of Figures 1 to 8 , the example of Figures 16 to 19 further includes a seal 207 and a film 205, and a seal 115 and a film 111. During use, the film 205 and the film 111 can be pierced by the connector 300, forming a seal between the seal 207 (or seal 115) and the connector 300.

[0138] Unlike the example shown in Figures 1-8 , the example shown in Figures 16-19 further includes a stopper 209, which is disposed within the housing assembly 201. The stopper 209 may be a baffle disposed within the housing assembly 201. Thus, when the other end of the connector 300 extends into the through-hole 203, the stopper 209 can limit the other end of the connector 300. This prevents the connector 300 from being fully inserted into the housing assembly 201, while also allowing the user to confirm that the connector 300 is fully inserted. It is understood that the stopper may also be disposed within the housing assembly 101, or within both the housing assembly 101 and the housing assembly 201.

[0139] It should be noted that the connector 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.

[0140] The following describes an electronic atomization device and a liquid storage component provided by yet another embodiment of the present application in conjunction with Figures 20 to 26. In the examples of Figures 20 to 26, reference can be made to the aforementioned parts for the parts with the same reference numerals as those in Figures 1 to 8.

[0141] Unlike the examples of Figures 1 to 8 , in the examples of Figures 20 to 26 , a liquid storage medium is provided in the liquid storage chamber 103. When the liquid storage medium reaches a saturated state after injection, the amount of the liquid storage medium is between 0.1 ml and 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, etc. One end of the through hole 110 is connected to the air portion above the liquid storage medium in the liquid storage chamber 103. In a specific embodiment, a gap may be provided between the liquid storage medium and the inner surface of the liquid storage chamber 103 so that one end of the through hole 110 is connected to the air portion above the liquid storage medium in the liquid storage chamber 103. Alternatively, the dimension of the liquid storage medium along the length direction of the electronic atomization device 100 is smaller than the distance between the bottom of the liquid storage chamber 103 and one end of the through hole 110, so that one end of the through hole 110 is connected to the air portion above the liquid storage medium in the liquid storage chamber 103.

[0142] Unlike the example shown in Figures 1-8 , the example shown in Figures 20-26 further includes a switch member disposed on the housing assembly 201. The switch member is configured to selectively open or close the through hole 203, thereby opening or closing the liquid passage. When the switch member opens the liquid passage, the second liquid matrix stored in the liquid storage chamber 202 can flow through the liquid passage to the liquid storage chamber 103, thereby replenishing the consumed liquid matrix in the liquid storage chamber 103 in a timely manner. When the switch member closes the liquid passage, the second liquid matrix stored in the liquid storage chamber 202 cannot flow through the liquid passage to the liquid storage chamber 103.

[0143] In the examples of FIG. 20 to FIG. 26 , the switch element includes a manually operated switch element to selectively open or close the liquid channel under manual operation of a user.

[0144] Specifically, the switch member includes an operating portion 210, which is configured to accept and respond to manual operations of the user to open or close the through hole 203, thereby opening or closing the liquid channel. The operating portion 210 is generally in the shape of an elongated strip, and a contact portion 210a is provided on the operating portion 210. A receiving cavity 201a2 is provided on the main body 201a of the shell assembly 201. The receiving cavity 201a2 extends along the thickness direction of the electronic atomization device 100, and the through hole 203 extends along the width direction of the electronic atomization device 100. The extension direction of the receiving cavity 201a2 is approximately perpendicular to the extension direction of the through hole 203 and the two are intersecting; such a structure enables the through hole 203 to communicate with the receiving cavity 201a2. The operating portion 210 is accommodated in the receiving cavity 201a2, and part of the operating portion 210 is located in the through hole 203, and the part of the operating portion 210 is provided with a through hole 210b. The contact portion 210 a is exposed on the housing assembly 201 .

[0145] The user can move the operating part 210 relative to the shell assembly 201 through the contact part 210a, and the movement range has a first position for opening the liquid channel and a second position for closing the liquid channel. For example, assuming that the initial position is the second position for closing the liquid channel, when the user operates the contact part 210a to rotate counterclockwise, the operating part 210 moves from the second position to the first position, at which time the through hole 210b is connected to the through hole 203, thereby opening the liquid channel (as shown in Figures 22-24); when the user operates the contact part 210a to rotate clockwise again, the operating part 210 moves from the first position to the second position, at which time the through hole 210b is misaligned with the through hole 203, thereby closing the liquid channel. It can be understood that the movement of the operating part 210 relative to the shell assembly 201 can also be in the form of sliding, rotating, etc., which is not limited in this application.

[0146] In the examples of Figures 20-26, a sealing member 211 is further included. The sealing member 211 is at least partially disposed between the operating portion 210 and the liquid passage to prevent leakage of the liquid matrix. Specifically, the sealing member 211 has a receiving cavity 211a for accommodating a portion of the operating portion 210. Two opposing side walls of the sealing member 211 also have through-holes 211b, which are axially aligned with the through-holes 210b. After assembly, the sealing member 211 can be accommodated in the receiving cavity 201a2, thereby closely contacting the inner surface of the receiving cavity 201a2 and the outer surface of the operating portion 210, thereby forming a seal. It is understood that the inner and outer surfaces of the sealing member 211 can be provided with protrusions or convex rings, which maintain contact with the inner surface of the receiving cavity 201a2 and the outer surface of the operating portion 210 through the protrusions or convex rings, thereby forming a good sealing effect.

[0147] In the example of Figures 20 to 26, a fixing hole 201a4 is further provided on the bottom wall 201a3 of the receiving cavity 201a2, and a fixing post 210c is further provided at one end of the operating portion 210. The fixing post 210c cooperates with the fixing hole 201a4 to retain the operating portion 210 on the housing assembly 201. It will be understood that a corresponding through hole 211c can be provided on the bottom wall of the receiving cavity 211a, and the fixing post 210c can be fixed in the fixing hole 201a4 after passing through the through hole 211c.

[0148] It should be noted that in the examples of Figures 20-26, the switch element includes a manually operated switch element to selectively open or close the liquid channel under manual operation of the user. In other examples, the switch element includes an electrically operated switch element to selectively open or close the liquid channel under electrical operation, which is also feasible. For example, when it is detected that the liquid matrix in the liquid storage chamber 103 is low, the liquid channel can be electrically opened to allow the second liquid matrix stored in the liquid storage chamber 202 to flow through the liquid channel to the liquid storage chamber 103, thereby replenishing the consumed liquid matrix in the liquid storage chamber 103 in a timely manner. For another example, when it is detected that the housing assembly 201 is connected to the housing assembly 101, the liquid channel can be electrically opened to allow the second liquid matrix stored in the liquid storage chamber 202 to flow through the liquid channel to the liquid storage chamber 103.

[0149] It should be noted that in the examples of Figures 20-26, the switch element selectively opens or closes the liquid passage. In other examples, another switch element configured to selectively open or close the air passage is also feasible. For example, similar to the examples of Figures 20-26, another switch element is provided on the housing assembly 201, and this other switch element is configured to selectively open or close the through hole 204, thereby opening or closing the air passage.

[0150] It should be noted that in the examples of Figures 20-26, the switch element is disposed on the housing assembly 201. However, in other examples, it is also feasible to dispose the switch element on the housing assembly 101. For example, the switch element disposed on the housing assembly 101 can selectively open or close the through hole 109, thereby opening or closing the liquid channel.

[0151] It should be noted that in the examples of Figures 20-26, the liquid channel is selectively opened or closed by a switch member provided on the housing assembly 201. The structural features of this switch member are also applicable to the examples of Figures 1-19 described above. For example, in the examples of Figures 16-19, the switch member selectively opens or closes the liquid transmission channel of the connector 300, thereby opening or closing the liquid channel.

[0152] It is understood that in the examples of Figures 1 to 19 above, the film element and the switch element can be used in combination. In other examples, it is also feasible to use only the switch element without the film element.

[0153] The following describes another embodiment of the electronic atomization device and liquid storage component provided by the present application in conjunction with Figures 26 to 31. In the examples of Figures 26 to 31, the same reference numerals as those in Figures 1 to 8 can be referred to the aforementioned parts.

[0154] Unlike the example shown in Figures 1 to 8 , in the example shown in Figures 26 to 31 , seal 207 is provided on the inner surface of the wall defining through-hole 203, and seal 208 is provided on the inner surface of the wall defining through-hole 204. When the wall defining through-hole 109 extends into through-hole 203, a seal is formed between seal 207 and the wall defining through-hole 109; when the wall defining through-hole 110 extends into through-hole 204, a seal is formed between seal 208 and the wall defining through-hole 110.

[0155] Unlike the example shown in Figures 1-8 , the example shown in Figures 26-31 further includes a switch member disposed on the housing assembly 201. The switch member is configured to selectively open or close the through hole 203, thereby opening or closing the liquid passage. When the switch member opens the liquid passage, the second liquid matrix stored in the liquid storage chamber 202 can flow through the liquid passage to the liquid storage chamber 103, thereby replenishing the consumed liquid matrix in the liquid storage chamber 103 in a timely manner. When the switch member closes the liquid passage, the second liquid matrix stored in the liquid storage chamber 202 cannot flow through the liquid passage to the liquid storage chamber 103.

[0156] In the examples of FIG. 26 to FIG. 31 , the switch element includes a manually-operated switch element to selectively open or close the liquid passage under manual operation of a user.

[0157] The switch member includes an operating portion configured to receive and respond to a manual operation of a user to open or close the through hole 203 , thereby opening or closing the liquid channel.

[0158] The operating portion includes a contact portion 210a and a movable portion 210d connected to the contact portion 210a. The contact portion 210a and the movable portion 210d can be detachably connected or formed as one piece. A receiving chamber 201a5 communicating with the through hole 203 is provided in the main body 201a of the shell assembly 201, and the receiving chamber 201a5 extends along the width direction of the electronic atomization device 100. The movable portion 210d is accommodated in the receiving chamber 201a5, and the movable portion 210d is roughly in the shape of a long stick. The movable portion 210d can move in the receiving chamber 201a5, for example, slide left and right along the width direction of the electronic atomization device 100; further, a seal (not shown) is provided between the movable portion 210d and the receiving chamber 201a5, such as a sealing ring sleeved on the movable portion 210d, to prevent leakage of the liquid matrix. The contact portion 210a is roughly in the shape of an inverted "L". One end of the contact portion 210 a passes through the housing assembly 201 and is connected to the movable portion 210 d , and the other end of the contact portion 210 a is exposed on an outer surface of the housing assembly 201 , such as the bottom wall of the housing assembly 201 .

[0159] The contact portion 210a is configured to accept user manipulation to drive the movable portion 210d to move relative to the housing assembly 201. Specifically, the user can use the contact portion 210a to move the contact portion 210a and the movable portion 210d relative to the housing assembly 201, for example, by sliding them left and right along the width of the electronic atomization device 100. This movement has a first position that opens the liquid passage and a second position that closes the liquid passage. For example, assuming that the initial position is the second position for closing the liquid channel (as shown in FIG29 ), when the user operates the contact portion 210a to slide to the right, the contact portion 210a drives the movable portion 210d to slide to the right together, moving from the second position to the first position. At this time, the through hole 203 is connected to the liquid storage chamber 202, thereby opening the liquid channel (as shown in R1 of FIG30 ); when the user operates the contact portion 210a to slide to the left again, the contact portion 210a drives the movable portion 210d to slide to the left together, moving from the first position to the second position. At this time, part of the movable portion 210d extends into the through hole 203, disconnecting or blocking the connection between the through hole 203 and the liquid storage chamber 202, thereby closing the liquid channel. It is understandable that the movement of the operating portion relative to the housing assembly 201 can also be in the form of sliding, rotating, etc., which is not limited in this application.

[0160] In one example, the user can repeatedly move the operating portion relative to the housing assembly 201 through the contact portion 210a, for example, repeatedly sliding left and right along the width direction of the electronic atomization device 100, thereby pumping the liquid matrix in the liquid storage chamber 202 into the liquid storage chamber 103.
