Description

Electronic atomization device and liquid storage components Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an electronic atomization device and a liquid storage component. Background Art

[0002] 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.

[0003] Due to various factors, such as cost, regulations, etc., the amount of liquid matrix stored inside the atomizer is generally relatively small. When the liquid matrix is ​​consumed, it can be continued to be used by filling it with liquid, replacing the atomizer, etc., or it can be directly discarded. On the one hand, the above method brings inconvenience to the user and reduces the user's usage experience, and on the other hand, it increases the user's usage cost. An existing electronic atomization device can replenish the liquid matrix to the electronic atomization device through a liquid storage component with a larger capacity, thereby reducing the user's usage cost and improving the user's usage experience. However, a problem with this device is that the amount of liquid matrix replenished by the liquid storage component to the electronic atomization device is uncontrollable, which in turn affects the user's suction experience. For example: when the liquid storage component replenishes a large amount of liquid matrix to the electronic atomization device, there is a phenomenon that the user is likely to inhale the liquid matrix and leakage is likely to occur; and when the liquid storage component replenishes a small amount of liquid matrix to the electronic atomization device, the atomization component is at risk of local overheating due to lack of liquid.

[0004] Summary of the Invention

[0005] The present application aims to provide an electronic atomization device and a liquid storage component to control the amount of liquid matrix delivered to the atomization component and enhance the user's puffing experience.

[0006] On one hand, the present application provides an electronic atomization device, comprising:

[0008] an atomizing assembly disposed in the first housing assembly, the atomizing assembly being used to atomize the liquid matrix from the liquid adsorption element to generate an aerosol;

[0009] a second housing assembly, independent of the first housing assembly, wherein a second liquid storage cavity for storing a liquid matrix is ​​formed in the second housing assembly; the second housing assembly is configured to be connectable to the first housing assembly and to establish a liquid channel for the liquid matrix to flow and an air channel for the air to flow between the first and second liquid storage cavities;

[0010] Part of the surface of the liquid adsorption element is connected to the liquid channel, thereby absorbing the liquid matrix from the second liquid storage chamber through the liquid channel; the end of the air channel in the first liquid storage chamber is covered by the liquid adsorption element, and the liquid adsorption element is configured to retain a partial amount of liquid matrix, so that the retained liquid matrix can block the air flow between the air channel and the first liquid storage chamber, and when the liquid matrix retained in the liquid adsorption element is consumed, the air flow between the air channel and the first liquid storage chamber is reopened.

[0019] In one example, the port of the air channel located at the first liquid storage chamber and the port of the liquid channel located at the first liquid storage chamber are both arranged close to the bottom of the first liquid storage chamber.

[0020] In one example, in the longitudinal direction of the second housing assembly, a port of the air channel located in the second liquid storage chamber is higher than a port of the liquid channel located in the second liquid storage chamber.

[0021] In one example, the port of the air channel located in the first liquid storage chamber is connected to the port of the liquid channel located in the first liquid storage chamber through a second gap, and the second gap is defined between the surface of the liquid adsorption element and the inner wall surface of the first liquid storage chamber.

[0022] In one example, the liquid adsorption element includes a liquid conducting element at least partially covering the liquid channel and a liquid storage medium in contact with the liquid conducting element.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] As shown in Figures 1 to 5, the electronic atomization device 100 provided in one embodiment of the present application includes a shell assembly 101. 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 in one piece.

[0069] 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.

[0070] The housing assembly 101 is formed with a liquid storage chamber 103 that is used to store the first liquid matrix. The first liquid matrix can be a liquid that comprises a tobacco-containing substance that contains volatile tobacco flavor components, or can be a liquid that comprises a non-tobacco substance. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavorings or vitamin mixture. Spices can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but are not limited to this. Flavorings can comprise the composition that can provide multiple fragrance or local flavor to the user. Vitamin mixture can be a material that is mixed with at least a among vitamin A, vitamin B, vitamin C and the vitamin E, but are not limited to this. In addition, the first liquid matrix can comprise an aerosol forming agent such as glycerol and propylene glycol.

[0071] A liquid storage medium 103a is provided in the liquid storage chamber 103, a sealing member 103b is provided at the upper end of the liquid storage chamber 103, and a sealing member 103c is provided at the lower end of the liquid storage chamber 103. The upper and lower ends of the liquid storage chamber 103 are sealed by the sealing members 103b and 103c.

[0072] The liquid storage medium 103a is made of, for example, a fibrous or porous material. As shown in FIG6 , the liquid storage medium 103a has a generally tubular structure. The liquid storage medium 103a can absorb and retain the first liquid matrix and provide the first liquid matrix to the atomization assembly 104. After injection, when the liquid storage medium 103a reaches saturation, the liquid matrix content in the liquid storage medium 103a ranges from 0.1 ml to 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml. The space between the end surface of the liquid storage medium 103a and the sealing member 103b defines an air portion.

[0073] An atomizing assembly 104 is disposed in the housing assembly 101 , and the atomizing assembly 104 is used to atomize a liquid matrix to generate an aerosol.

[0074] As shown in Figure 7, the atomization assembly 104 includes a liquid-conducting element 104a and a heating element 104b. The liquid-conducting element 104a can absorb the liquid matrix in the liquid storage medium 103a and transfer the liquid matrix to the heating element 104b. The heating element 104b can be heated by supplying an electric current and transfers heat to the liquid matrix in contact with the heating element 104b to heat the liquid matrix, thereby generating an aerosol.

[0075] The liquid-conducting element 104a is configured as a tubular structure. It is understood that it can also be a plate-like structure or other regular or irregular shapes. The liquid-conducting element 104a can be made of a flexible fiber material, such as cotton fiber, non-woven fabric, or sponge. Alternatively, in other examples, the liquid-conducting element 104a can be a rigid porous body, such as porous ceramic or porous glass. The outer surface of the liquid-conducting element 104a has a radially outwardly projecting portion 104a1.

[0076] The heating element 104b is arranged close to the inner surface of the liquid-conducting element 104a, and can be abutted against the inner surface of the liquid-conducting element 104a, or partially or completely embedded in the liquid-conducting element 104a. The heating element 104b can be a resistance heating mesh, a resistance heating coil, etc. The heating element 104b can be made of a material with suitable resistance temperature coefficient characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In one example, the heating element 104b can be formed by winding a sheet or mesh substrate, and the wound heating element 104b is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with a side opening extending along the length direction of the electronic atomization device 100. Conductive pins 104c and conductive pins 104d are welded or arranged at both ends of the heating element 104b for guiding current on the heating element 104b. In other examples, the heating element 104b can be arranged as a structure wound around the liquid-conducting element 104a.

[0077] An airflow channel 105 is also provided within the housing assembly 101 to transport the aerosol generated by the atomizer assembly 104 to the mouthpiece 102 for inhalation by the user. The lower end of the airflow channel 105 communicates with an air inlet, which can be located on a sidewall of the housing assembly 101; the upper end of the airflow channel 105 is connected to the mouthpiece 102, i.e., communicates with the air outlet (the dotted arrows in the figure indicate the direction of airflow in the airflow channel 105).

[0078] As shown in FIG8 , a connecting tube 105a is provided within the housing assembly 101. The hollow portion within the connecting tube 105a defines a portion of the airflow channel 105. The connecting tube 105a extends axially along the liquid storage chamber 103. The upper end of the connecting tube 105a is connected to the sealing member 103b, and the lower end of the connecting tube 105a is connected to the sealing member 103c. The connecting tube 105a is preferably made of a thin, rigid material, such as fiberglass or stainless steel.

[0079] In a preferred embodiment, the liquid storage medium 103a is sleeved on the connecting tube 105a; the inner diameter of the liquid storage medium 103a is slightly smaller than the outer diameter of the connecting tube 105a, so that the liquid storage medium 103a is tightly sleeved on the connecting tube 105a. The atomizer assembly 104 is disposed within the connecting tube 105a. The atomizer assembly 104 and the connecting tube 105a are coaxially arranged. The side wall of the connecting tube 105a also has a liquid guide port 105a1 arranged near the lower end of the connecting tube 105a. The liquid storage medium 103a covers the liquid guide port 105a1, and part of the liquid guide element 104a is exposed to the liquid storage cavity 103 through the liquid guide port 105a1, so that the part of the liquid guide element 104a is arranged close to the liquid storage medium 103a or maintains contact with the liquid storage medium 103a, thereby allowing the liquid matrix in the liquid storage cavity 103 to flow into the atomization component 104 through the liquid guide port 105a1, that is, it is sucked by the liquid guide element 104a and atomized by the heating element 104b to generate an inhalable aerosol.

[0080] The sidewall of the connecting tube 105a is also provided with a notch 105a2, extending from the lower end of the connecting tube 105a toward the upper end of the connecting tube 105a. The protruding portion 104a1 of the liquid-conducting element 104a extends into the notch 105a2, thereby being exposed to the liquid storage chamber 103. After assembly, the liquid storage medium 103a maintains contact with a portion of the protruding portion 104a1, thereby facilitating the liquid-conducting element 104a to absorb the liquid medium.

[0081] 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.

[0082] Circuit 106 includes at least one control unit. The control unit may include a logic gate array, or may include a combination of a general-purpose microcontroller and a memory storing a program executable in the microcontroller. In addition, those skilled in the art will appreciate that circuit 106 may include another type of hardware.

[0083] 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.

[0084] 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.

[0085] 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 5. For example, a puff detector 112 may also be provided in the housing assembly 101 for detecting the user's puffing action and generating a corresponding electrical signal, that is, detecting whether the electronic atomization device 100 is being puffed, so that the circuit 106, such as a control unit, 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 112 can adopt common pressure sensors, differential pressure sensors, airflow sensors, etc. The puff detector 112 is connected to the airflow channel 105, so that when the user puffs, it can sense the changes in the puff airflow.

[0086] It should also be noted that in the examples of Figures 1-5 , 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.

[0087] Please refer to Figures 10 to 13 for understanding. The liquid storage component 200 provided in one embodiment of the present application includes a shell assembly 201. The shell assembly 201 can be composed of multiple components, such as a main body 201a, a bottom cover 201b, a seal 201c and a seal 201d.

[0088] The main body 201a is connected to the bottom cover 201b. In a preferred embodiment, the main body 201a and the bottom cover 201b are detachably connected, for example, by a snap-fit ​​connection. A portion of the bottom cover 201b extends into the main body 201a. The main body 201a and the bottom cover 201b together define a liquid storage chamber 202 for storing a second liquid matrix. In a further embodiment, the bottom cover 201b is provided with a liquid injection port 201b1, through which the second liquid matrix can be injected into the liquid storage chamber 202. The liquid injection port 201b1 can be sealed by a sealing member or by other means, which is not limited in this application. A sealing member 201c is provided between the bottom cover 201b and the main body 201a to prevent leakage of the second liquid matrix from the gap between the bottom cover 201b and the main body 201a. In a preferred embodiment, a groove 201b2 is provided on the outer surface of the bottom cover 201b, and the sealing member 201c is annular and at least partially received in the groove 201b2, thereby achieving sealing between the bottom cover 201b and the main body 201a.

[0089] 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 in 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.

[0090] It should be noted that the composition or properties of the second liquid matrix may be different from or the same as those of the first liquid matrix. For example, in some examples, the second liquid matrix and the first liquid matrix have different components, or the concentrations of the second liquid matrix and the first liquid matrix are different. For example, in other examples, the second liquid matrix and the first liquid matrix have exactly the same composition, the second liquid matrix may be part of a certain liquid formula, and the first liquid matrix may be another part of a certain liquid formula, and the second liquid matrix may be introduced into the liquid storage chamber 103 as a supplementary source of the first liquid matrix, thereby increasing the number of puffs of the electronic atomization device.

[0091] 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, 2 ml, 4 ml, 5 ml, 6 ml, 8 ml, 10 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 for air and the other for the liquid matrix. Typically, liquid storage medium 103a is not provided in liquid storage chamber 202.

[0092] The liquid storage component 200 is independent of the main body of the electronic atomization device 100. For example, when the product is in a packaged or unused state, the liquid storage component 200 is separated from the main body of the electronic atomization device 100, namely the housing assembly 101. The user can assemble the liquid storage component 200 on the housing assembly 101 before use. In one example, the liquid storage component 200 and the electronic atomization device 100 are detachably connected, that is, the housing assembly 201 and the housing assembly 101 are detachably connected, such as by a snap connection, a magnetic connection, etc. In one example, once the liquid storage component 200 is connected to the electronic atomization device 100, it cannot be removed again.

[0093] The shell assembly 101 is also 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 runs 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 card slot 108a, and the outer wall of the shell assembly 201 is provided with a snap connector (not shown). The snap connection between the shell assembly 201 and the shell assembly 101 is achieved by the cooperation of the card slot 108a and the snap connector. 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.

[0094] 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 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. It is understood that the arrangement of the liquid storage chamber 103 and the liquid storage chamber 202 is not limited to the above situation.

[0095] When the housing assembly 201 is connected to the housing assembly 101 , the air portion of the liquid storage chamber 103 is connected to the air portion of the liquid storage chamber 202 , and the liquid matrix in the liquid storage chamber 202 can be replenished into the liquid storage chamber 103 in a timely manner.

[0096] Specifically, the housing assembly 101 further includes a through hole 109 and a through hole 110, which are spaced apart. One end of through hole 109 communicates with the liquid storage chamber 103, while the other end protrudes from the right side wall of the receiving chamber 108 and communicates with the exterior of the housing assembly 101. One end of through hole 110 communicates with the liquid storage chamber 103, while the other end protrudes from the right side wall of the receiving chamber 108 and communicates with the exterior of the housing assembly 101. Through through hole 109, liquid matrix can be added to the liquid storage chamber 103, while through through hole 110, air can be added to or removed from the liquid storage chamber 103. Through hole 109 can be positioned adjacent to through hole 110, for example, directly adjacent to through hole 110. Alternatively, through hole 109 and through hole 110 can be spaced apart by a certain distance. In some examples, positioning through hole 109 adjacent to through hole 110 is advantageous in that the same sealing member can be used to connect through holes 109, 110, and the liquid storage assembly, thereby improving sealing reliability.

[0097] In one specific implementation, one end of the through hole 110 can be connected to the air portion of the liquid storage chamber 103 through the gap between the liquid storage medium 103a and the wall defining the liquid storage chamber 103. For example, the liquid storage medium 103a has a notch groove 103a1, and a gap is formed between the notch groove 103a1 and the wall defining the liquid storage chamber 103, thereby allowing the through hole 110 to communicate with the air portion of the liquid storage chamber 103; or, the liquid storage medium 103a has an air vent, and the through hole 110 is connected to the air portion of the liquid storage chamber 103 through the air vent.

[0098] In one example, external air can also communicate with the air portion of the liquid storage chamber 103 through the gap between the connecting tube 105 a and the sealing member 103 c .

[0099] When the housing assembly 201 is not connected to the housing assembly 101 , the through hole 109 or the through hole 110 may be sealed by a sealing member, such as a removable silicone plug or silicone cap, or a puncturable film.

[0100] The bottom cover 201b is further provided with a receiving chamber 201b3, a through hole 201b4, and a through hole 201b5. The receiving chamber 201b3 communicates with the exterior of the housing assembly 201. One end of the through hole 201b4 is located near the bottom of the liquid storage chamber 202 and communicates with the liquid storage chamber 202, while the other end of the through hole 201b4 communicates with the receiving chamber 201b3. In a further embodiment, the bottom of the liquid storage chamber 202 is further provided with an inclined portion 201b6 that is inclined toward one end of the through hole 201b4. The inclined portion 201b6 is used to guide the liquid matrix toward the end of the through hole 201b4, thereby preventing it from accumulating at the bottom of the liquid storage chamber 202, thereby improving the utilization rate of the liquid matrix. The through hole 201b5 is spaced apart from the through hole 201b4. The through hole 201b5 can be adjacent to the through hole 201b4 or spaced a certain distance apart from the through hole 201b4. The through hole 201b5 can replenish or exhaust air into or out of the liquid storage chamber 202. One end of the wall defining the through hole 201b5 extends into the liquid storage chamber 202 and is arranged close to the top of the liquid storage chamber 202, thereby facilitating direct communication with the air portion of the liquid storage chamber 202. The other end of the through hole 201b5 is communicated with the receiving chamber 201b3.

[0101] The sealing member 201d is at least partially housed within the receiving chamber 201b3. The sealing member 201d defines a receiving chamber 201d1, a through hole 201d2, and a through hole 201d3. The receiving chamber 201d1 communicates with the exterior of the housing assembly 201. One end of the through hole 201d2 is located on the left side wall of the sealing member 201d, and the other end communicates with the receiving chamber 201d1. One end of the through hole 201d3 is located on the top wall of the sealing member 201d, and the other end communicates with the receiving chamber 201d1.

[0102] As shown in FIG4 , when housing assembly 201 is not connected to housing assembly 101, the other end of through hole 201b4, or at least a portion of the wall defining through hole 201b4, extends into through hole 201d2, thereby connecting through hole 201b4 with through hole 201d2. The other end of through hole 201b5 is offset from one end of through hole 201d3, thereby disconnecting through hole 201b5 from through hole 201d3. In other words, the other end of through hole 201b5 is sealed by sealant 201d, thereby closing through hole 201b5. In this case, through hole 201d2 and / or through hole 201d3 can be sealed by other sealants, such as a removable silicone plug or cap, or a puncturable film. Since through hole 201b5 is sealed by sealant 201d, it is also possible to consider not sealing through hole 201b5 by other sealants.

[0103] When the shell component 201 is assembled onto the shell component 101 from the left side of the shell component 101, at least part of the wall defining the through hole 109 and the through hole 110 extends into or is accommodated in the accommodating cavity 201b3, thereby abutting against the seal, and the through hole 109 is connected with the through hole 201d2, and the through hole 110 is connected with the through hole 201d3, thereby making the through hole 109 connected with the through hole 201b4. Since the through hole 201b5 is blocked by the seal 201d, the through hole 110 and the through hole 201b5 are not connected in the initial connection state.

[0104] When the housing assembly 201 is further assembled onto the housing assembly 101 from the left side of the housing assembly 101, the sealing member 201d is squeezed or pushed by the walls defining the through-holes 109 and 110, thereby being driven to move into the receiving cavity 201b3 (at this time, the wall defining the through-hole 201b4 moves in the through-hole 201d2). When the sealing member 201d moves a certain distance into the receiving cavity 201b3 or moves into position, for example, when the end of the wall defining the through-hole 201d2 abuts the bottom of the receiving cavity 201b3, the other end of the through-hole 201b5 is aligned with one end of the through-hole 201d3, thereby connecting the through-hole 201b5 with the through-hole 201d3, and further connecting the through-hole 110 with the through-hole 201b5, that is, opening the through-hole 201b5 (first position). The other end of the through-hole 201b4 or at least a portion of the wall defining the through-hole 201b4 moves in the through-hole 201d2. In this way, the air portion of the liquid storage chamber 103 is communicated with the air portion of the liquid storage chamber 202 , and the liquid matrix in the liquid storage chamber 202 can be replenished into the liquid storage chamber 103 in a timely manner.

[0105] In this case, through-holes 201b4, 201d2, and 109 collectively define a liquid channel T1, thereby providing a fluid path between the liquid storage chamber 103 and the liquid storage chamber 202 through which the first liquid matrix and / or the second liquid matrix can flow. One end of the liquid channel communicates with the liquid storage chamber 103, while the other end communicates with the liquid storage chamber 202. Through-holes 201b5, 201d3, and 110 collectively define an air channel T2, thereby providing an air path for air exchange between the liquid storage chamber 103 and the liquid storage chamber 202. One end of the air channel T2 communicates with the air portion of the liquid storage chamber 103, while the other end communicates with the air portion of the liquid storage chamber 202. The air passage T2 can balance the pressure difference between the liquid storage chamber 103 and the liquid storage chamber 202, allowing the second liquid matrix stored in the liquid storage chamber 202 to flow smoothly through the liquid passage T1 to the liquid storage chamber 103, thereby promptly replenishing the consumed liquid matrix in the liquid storage chamber 103 and preventing the negative pressure generated by the decrease in the liquid matrix in the liquid storage chamber 103 from preventing the remaining liquid matrix from further flowing into the liquid storage chamber 202. In one example, as can be seen above, external air can also communicate with the air portion of the liquid storage chamber 103 through the gap between the connecting tube 105a and the sealing member 103c. Therefore, external air can also achieve air exchange with the air portion of the liquid storage chamber 103 and / or the air portion of the liquid storage chamber 202.

[0106] In the above embodiment, the air channel T2 is arranged adjacent to the liquid channel T1. The port T1a at one end of the liquid channel T1 and the port T2a at one end of the air channel are spaced apart along the axial direction of the electronic atomization device 100 or the liquid storage chamber 103, and the port T2a of the air channel is located above the port T1a of the liquid channel. In some examples, along the axial direction of the electronic atomization device 100, the port T1a of the liquid channel and the port T2a of the air channel are both arranged close to the bottom of the liquid storage chamber 103, that is, both are arranged away from the nozzle 102; in the axial direction of the electronic atomization device 100, the port T1a of the liquid channel is further away from the nozzle 102 of the electronic atomization device 100 than the port T2a of the air channel.

[0107] In a further embodiment, a liquid-conducting element 111 is further provided in the liquid storage chamber 103. As shown in FIG9 , the liquid-conducting element 111 is roughly tubular in structure. The liquid-conducting element 111 and the liquid storage medium 103a are arranged in sequence along the axial direction of the liquid storage chamber 103. The liquid-conducting element 111 is arranged close to the through hole 109 and the through hole 110, that is, the liquid-conducting element 111 is connected to the liquid channel, and the through hole 109 and the through hole 110 are both covered by the liquid-conducting element 111. The upper surface of the liquid-conducting element 111 is in contact with the lower surface of the liquid storage medium 103a, the lower surface of the liquid-conducting element 111 is in contact with the bottom of the liquid storage chamber 103, and the outer surface of the liquid-conducting element 111 is in contact with the wall defining the liquid storage chamber 103. In this way, when the second liquid matrix in the liquid storage chamber 202 flows through the liquid channel to the liquid storage chamber 103, it can be sucked up by the liquid-conducting element 111 and transferred to the liquid storage medium 103a, and then indirectly transferred to the liquid-conducting element 104a in the atomizer assembly 104, that is, it is sucked up by the liquid-conducting element 104a in the atomizer assembly 104. This arrangement can make the second liquid matrix stored in the liquid storage chamber 202 flow more smoothly to the atomizer assembly 104, avoiding the problem of abnormal noise when the user puffs due to a fast liquid supply rate and the user easily inhaling the liquid matrix.

[0108] In the above embodiment, the material of the liquid-conducting element 111 can be the same as or different from the liquid storage medium 103a. The density of the liquid-conducting element 111 is greater than the density of the liquid storage medium 103a. In this way, on the one hand, it can be ensured that the liquid-conducting element 111 can strongly absorb the liquid matrix in the liquid channel, so that the liquid matrix in the liquid-conducting element 111 is smoothly transferred to the liquid storage medium 103a. On the other hand, the liquid-conducting element 111 can slow down the oversaturation of the liquid storage medium 103a and reduce the probability of liquid matrix leakage. In other examples, the liquid-conducting element 111 and the liquid storage medium 103a use the same fiber material, and both can play the role of absorbing the liquid matrix from the liquid channel, i.e., the through hole 109, and transferring it to the atomization component 104. The liquid-conducting element 111 and the liquid storage medium 103a can be used as a liquid adsorption element of an integrated structure filled in the liquid storage cavity 103.

[0109] In the above embodiment, since the outer surface of the liquid-conducting element 111 maintains contact with the wall defining the liquid storage chamber 103, in order to avoid the air channel from being blocked, there can be a certain gap J1 between the wall defining the liquid storage chamber 103 (i.e., the inner wall surface of the liquid storage chamber 103) and the outer surface of the liquid-conducting element 111, so that the air in the liquid storage chamber 103 can flow to the above gap J1 through the notch groove 103a1 on the side wall of the liquid storage medium 103a, and enter the air channel through the gap J1 to replenish the air into the liquid storage chamber 202, thereby achieving the balance of air pressure between the liquid storage chamber 103 and the liquid storage chamber 202.

[0110] In the above embodiment, the port T2a at one end of the air channel, i.e., the port at one end of the through hole 110, is covered by the liquid-conducting element 111. When the liquid-conducting element 111 and the liquid storage medium 103a absorb the liquid matrix, the air channel T2 may be blocked by the liquid matrix retained in the liquid-conducting element 111 and the liquid storage medium 103a. For example, as shown in FIG13 , when the level of the liquid matrix absorbed by the liquid-conducting element 111 and the liquid storage medium 103 a reaches the schematic line Y in the figure (the schematic line Y may be a horizontal line or a non-horizontal line), the port T2a of the through hole 110 located at one end of the liquid storage chamber 103 is blocked, and the gap J1 between the liquid-conducting element 111 and the through hole 110 is also blocked by the liquid matrix seeping from the liquid-conducting element 111 and / or the liquid storage medium 103 a, so that air exchange between the liquid storage chamber 103 and the liquid storage chamber 202 through the air channel T2 cannot be achieved. The air pressure difference between the two causes the liquid storage chamber 202 to gradually reduce or even stop replenishing the liquid matrix to the liquid storage chamber 103.

[0111] When the electronic atomization device 100 is sucked (the liquid matrix in the liquid-conducting element 111 and the liquid storage medium 103a is consumed) and the liquid matrix level schematic line Y gradually decreases, the liquid matrix blocked in the air channel T2 and the above-mentioned gap J1 will also be re-absorbed by the liquid-conducting element 111. When the liquid matrix level drops to a position below the through-hole 110, the air in the through-hole 110 and the liquid storage chamber 103 is partially connected, and the air connection between the liquid storage chamber 103 and the liquid storage chamber 202 is restored through the air channel T2, and the liquid storage chamber 202 resumes replenishing the liquid matrix to the liquid storage chamber 103 (the dotted arrows in the figure, one is the air flow direction of the air channel T2, and the other is the liquid matrix flow direction of the liquid channel T1). In this way, the liquid matrix retained in the liquid-conducting element 111 and the liquid storage medium 103a alternately blocks and conducts the air channel T2, so that the liquid storage chamber 202 can automatically and quantitatively provide the liquid matrix to the atomizer component 104, and when the liquid matrix near the atomizer component 104 is consumed and reduced, the liquid supply can be automatically restored, thereby improving the user's puffing experience and avoiding adverse risks such as liquid leakage and abnormal puffing noise caused by excessive liquid matrix provided to the atomizer component 104.

[0112] In the above embodiment, when the electronic atomization device 100 is not in use, the air portion of the air channel T2 and the liquid storage chamber 103 is blocked by the liquid matrix retained in the liquid adsorption element (liquid conducting element 111 and liquid storage medium 103a); when the electronic atomization device 100 is in the suction state or during the lag period after suction, the air portion of the air channel T2 and the liquid storage chamber 103 is connected.

[0113] In the above embodiment, when the amount of liquid matrix drawn by the liquid-conducting element 111 and the liquid storage medium 103a reaches a first predetermined amount, the port T2a of the through hole 110 at one end of the liquid storage chamber 103 is blocked. When the amount of liquid matrix in the liquid-conducting element 111 and the liquid storage medium 103a is consumed by a second predetermined amount, the port T2a of the through hole 110 at one end of the liquid storage chamber 103 is opened. The first predetermined amount and the second predetermined amount are substantially the same. Substantially the same means that the difference between the two amounts is within 20 microliters (μL), or within 15 μL, or within 10 μL, or within 6 μL, or within 4 μL.

[0114] In one example, if the distance between the port T1a of the through hole 109 at one end of the liquid storage chamber 103 and the port T2a of the through hole 110 at one end of the liquid storage chamber 103 is too large, it is easy to cause an excessive amount of liquid matrix to be provided to the atomizer assembly 104. Generally, the port T1a of the through hole 109 at one end of the liquid storage chamber 103 and the port T2a of the through hole 110 at one end of the liquid storage chamber 103 are both arranged close to the atomizer assembly 104 (along the horizontal direction of the liquid storage chamber 103). The longitudinal distance between the port T1a of the through hole 109 at one end of the liquid storage chamber 103 and the port T2a of the through hole 110 at one end of the liquid storage chamber 103 is between 1 mm and 8 mm, so that the liquid matrix provided from the liquid storage chamber 202 is basically maintained in the area around the atomizer assembly 104. Therefore, in product design, the amount of liquid matrix provided to the atomizer assembly 104 can be appropriately controlled by adjusting the spacing between the through hole 109 and the through hole 110. In a specific implementation, the above spacing distance may be between 2 mm and 8 mm, or between 2 mm and 6 mm, or between 2 mm and 4 mm.

[0115] In one example, the distance between the port T1a at one end of the liquid storage chamber 103 where the through hole 109 is located or the port T2a at one end of the liquid storage chamber 103 where the through hole 110 is located and the atomizer assembly 104 in the horizontal direction of the liquid storage chamber 103 is between 2 and 8 mm. In a specific implementation, it can be between 2 mm and 6 mm, or between 2 mm and 5 mm, or between 2 mm and 4 mm.

[0116] Correspondingly, the axial distance between the port T2a of the through hole 110 at one end of the liquid storage chamber 103 and the bottom of the liquid storage chamber 103 is between 2 mm and 10 mm. In specific implementations, it can be between 2 mm and 8 mm, or between 2 mm and 6 mm, or between 2 mm and 4 mm, or between 2 mm and 3 mm. This distance is at least one factor that affects the amount of liquid matrix provided to the atomizer assembly 104.

[0117] Correspondingly, the axial distance between the upper and lower surfaces of the liquid-conducting element 111 is between 2 mm and 12 mm. In specific implementations, it can be between 2 mm and 10 mm, or between 2 mm and 8 mm, or between 2 mm and 6 mm, or between 2 mm and 4 mm.

[0118] In the above embodiment, the liquid-guiding element 111 is sleeved on the connecting tube 105a, that is, the liquid-guiding element 111 is arranged around the connecting tube 105a. The liquid-guiding element 111 is located between the liquid channel and the atomizing assembly 104. The inner diameter of the liquid-guiding element 111 is larger than the outer diameter of the connecting tube 105a, so that a space is maintained between the inner surface of the liquid-guiding element 111 and the outer surface of the connecting tube 105a, and the liquid-guiding element 111 and the atomizing assembly 104 are spaced apart. In this way, when the second liquid matrix in the liquid storage chamber 202 flows through the liquid channel to the liquid storage chamber 103, it can be absorbed by the liquid-guiding element 111 and transferred to the liquid storage medium 103a, thereby indirectly transferred to the atomizing assembly 104. In this way, the liquid guiding element 111 can adjust or slow down the rate at which the liquid channel supplies the atomizer assembly 104, thereby avoiding excessive liquid supply to the atomizer assembly 104, which may cause the atomizer assembly 104 to produce abnormal noise during suction use; in addition, the liquid guiding element 111 does not directly contact the atomizer assembly 104, and the liquid storage medium 103a only partially contacts the atomizer assembly 104 (the liquid storage medium 103a only covers part of the atomizer assembly 104 in the longitudinal or axial direction), thereby avoiding the atomizer assembly 104 from saturating the amount of liquid absorbed by the atomizer assembly 104, and can reduce the risk of the liquid matrix leaking from the liquid storage chamber 103 to the outside (for example, leaking to the circuit 106).

[0119] In the above embodiment, the axial distance between the bottom of the liquid storage chamber 103 and the liquid guide port 105a1 of the connecting tube 105a is greater than the axial distance between the bottom of the liquid storage chamber 103 and the lower surface of the liquid storage medium 103a. Alternatively, the axial distance between the bottom of the liquid storage chamber 103 and the liquid guide port 105a1 of the connecting tube 105a is greater than the axial distance between the upper and lower surfaces of the liquid guide element 111. In this way, when the second liquid matrix in the liquid storage chamber 202 flows into the liquid storage chamber 103 through the liquid channel, it will not be directly absorbed by the liquid guide element 104a in the atomizer assembly 104 through the liquid guide port 105a1. This helps to slow the rate at which the liquid matrix reaches the liquid guide element 104a.

[0120] In the above embodiment, since the protruding portion 104a1 of the liquid-conducting element 104a extends into the notch 105a2 of the connecting tube 105a and is exposed in the space between the inner surface of the liquid-conducting element 111 and the outer surface of the connecting tube 105a, the liquid matrix in the space can be absorbed by the liquid-conducting element 104a, thereby reducing the risk of the liquid matrix leaking from the liquid storage chamber 103 to the outside.

[0121] In further implementations, since the liquid matrix in the liquid storage chamber 202 may flow into the through hole 201b5 (for example, during the injection process, or during the horizontal placement or inversion process, etc.), during the assembly of the housing assembly 201 to the housing assembly 101, the seal 201d can be pushed to move from the starting position (refer to the position of the seal 201d shown in Figure 4) to the end position (refer to the position of the seal 201d shown in Figure 3) within the receiving chamber 201b3, thereby compressing the space in the receiving chamber 201b3. At this time, the gas in the compressed space can be discharged toward the through hole 201b5 through the gap between the seal 201d and the receiving chamber 201b3, thereby discharging the liquid matrix in the through hole 201b5 back to the liquid storage chamber 202, thereby preventing the liquid matrix from blocking the air passage. The gap between the seal 201d and the receiving chamber 201b3 can be at least partially defined by an exhaust groove 201d4 provided on the outer surface of the seal 201d. One end of the exhaust groove 201d4 is located close to the through hole 201d3, and the other end extends to the left side wall of the sealing member 201d.

[0122] In some examples, as the seal 201d moves from the starting position to the ending position, the air passage between the two liquid storage chambers is closed, while the liquid passage between the two remains connected. In other words, as the seal 201d is pushed until the through hole 201b5 and the through hole 201d3 are connected to each other, the space of the receiving chamber 201b3 can be continuously compressed, thereby increasing the air pressure within the liquid storage chamber 202. This is beneficial for forcing the liquid matrix in the liquid storage chamber 202 to transfer into the liquid storage chamber 103.

[0123] In further implementations, the outer surface of the seal 201d is further provided with a plurality of protrusions 201d5, which abut against the inner surface of the liquid storage chamber 202, thereby forming a good sealing effect. As can be seen in Figures 11 and 12, there is at least one protrusion 201d5 between one end of the vent groove 201d4 and the through hole 201d3. Thus, when the other end of the through hole 201b5 is aligned with one end of the through hole 201d3, the at least one protrusion 201d5 can separate the vent groove 201d4 from the through hole 201b5, ensuring the airtightness of the air passage.

[0124] It should be noted that in the above example, through-holes 109 and 110 are positioned adjacent to each other, and through-holes 201b4 and 201b5 are also positioned adjacent to each other, with separate sealing members 201d being used to achieve the above function. In other examples, through-holes 109 and 110 may be positioned a certain distance apart, and through-holes 201b4 and 201b5 may be positioned a certain distance apart, with two separate sealing members being used to achieve the above function. This is also feasible.

[0125] It should be noted that the main body and the liquid storage component 200 of the above-mentioned electronic atomization device 100 are independent of each other. Before the main body and the liquid storage component 200 of the electronic atomization device 100 are not connected (that is, before the shell component 101 is connected to the shell component 201), the main body can be used alone and sucked, and the atomization component 104 only atomizes the first liquid matrix. After the main body and the liquid storage component 200 are connected (that is, after the shell component 101 is connected to the shell component 201), the atomization component 104 can atomize both the first liquid matrix and the second liquid matrix. The combination of the main body and the liquid storage component 200 can also be collectively referred to as an electronic atomization device. In other examples, the atomizer or cigarette cartridge can be combined with the power supply component (or cigarette rod) first, and then connected to the liquid storage component 200 for use.

[0126] It should be noted that there may be multiple liquid storage components 200 .

[0127] It should be noted that in other examples, the electronic atomization device cannot be used and inhaled before the housing assembly 201 is connected to the housing assembly 101. That is, the electronic atomization device can be used and inhaled only 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.

[0128] It should be noted that in some examples, no airflow channel is provided within the housing assembly 201. In other examples, a portion of the airflow channel may be provided within the housing assembly 201. When the housing assembly 201 is connected to the housing assembly 101, the airflow channel within the housing assembly 201 communicates with the airflow channel within the housing assembly 101, thereby forming a complete airflow channel for transmitting the aerosol generated by the atomizer assembly 104.

[0129] It should be noted that, in other examples, when the housing assembly 201 and the housing assembly 101 are in a connected state, the liquid storage cavity 202 is disposed around at least a portion of the liquid storage cavity 103 .

[0130] It should be noted that, in other examples, it is also feasible to connect the through hole 109 and the through hole 201d2, or the through hole 110 and the through hole 201d3, respectively, through an independent connector. In this case, the internal channel of the connector can also constitute a partial liquid channel or a partial air channel.

[0131] It should be noted that, in other examples, a switch member may be provided on the liquid channel (air channel), the switch member being configured to selectively open or close the liquid channel (air channel). The switch member may include a manually operated switch member to selectively open or close the liquid channel (air channel) under manual operation by a user. It is also feasible that the switch member includes an electrically operated switch member to selectively open or close the liquid channel (air channel) under electrical operation.

[0132] As shown in FIG14 , in other examples, one end of the wall defining the through hole 201b5 extends into the liquid storage chamber 202 but is not disposed near the top of the liquid storage chamber 202, which is also feasible. When the liquid matrix is ​​injected into the liquid storage chamber 202, the liquid matrix can flow into the through hole 201b5. When the housing assembly 201 is connected to the housing assembly 101, the liquid matrix in the through hole 201b5 can be discharged back to the liquid storage chamber 202, and the liquid matrix in the liquid storage chamber 202 can flow into the through hole 201d3 and then flow toward the through hole 110. When negative pressure is generated as the liquid matrix in the liquid storage chamber 103 decreases, the negative pressure can squeeze the liquid matrix in the through hole 201b5, the through hole 201d3, and the through hole 110 into the liquid storage chamber 202. At this time, the bubbles generated by the negative pressure can be discharged into the air portion of the liquid storage chamber 202 through the liquid matrix in the liquid storage chamber 202, thereby balancing the air pressure difference between the liquid storage chamber 103 and the liquid storage chamber 202. This allows the second liquid matrix stored in the liquid storage chamber 202 to flow smoothly through the liquid channel to the liquid storage chamber 103, and the consumed liquid matrix is ​​replenished to the liquid storage chamber 103 in a timely manner.

[0133] Figures 15-17 illustrate an electronic atomization device 100 and a liquid storage component 200 provided in another embodiment of the present application. In the examples of Figures 15-17 , components with the same reference numerals and their descriptions can refer to the examples of Figures 1-13 . It should be noted that in the examples of Figures 15-17 , the wall defining the through hole 201b5 is the same as that in the example of Figure 14 . It is understood that the structure of the examples of Figures 1-13 can also be used.

[0134] In the example of Figures 15-17 , unlike the example of Figures 1-13 , the port T1a at one end of the liquid channel T1 and the port T2a at one end of the air channel T2 are connected through a microchannel within the liquid storage chamber 103. Specifically, they can be connected through the gap J2 between the liquid-conducting element 111 and the wall defining the liquid storage chamber 103. For example, the outer surface of the liquid-conducting element 111 has a notch 111a, which defines at least a portion of the gap J2 between the liquid-conducting element 111 and the wall defining the liquid storage chamber 103, thereby connecting the liquid channel and the air channel. The purpose of such a setting is that when the product is shaken or placed in different postures, such as horizontal placement or inverted state, bubbles may enter the liquid channel T1 and block the liquid channel. Due to the height difference between the port T2b of the air channel T2 in the liquid storage chamber 202 and the port T1b of the liquid channel T1 in the liquid storage chamber 202 (the height difference h between the port T2b at one end of the through hole 201b5 and the port T1b at one end of the through hole 109 in the figure), a liquid pressure difference will be generated, so that the bubbles can flow to the air channel T2 through the gap J2 between the liquid-guiding element 111 and the wall defining the liquid storage chamber 103, and then be released into the air part of the liquid storage chamber 202, so that the liquid channel T1 is restored to normal (the dotted arrow in the figure indicates the flow direction of the bubbles in the liquid channel T1). It is understandable that the height difference between the port T2b of the air channel T2 in the liquid storage chamber 202 and the port T1b of the liquid channel T1 in the liquid storage chamber 202 also facilitates the liquid storage chamber 202 to replenish the liquid matrix to the liquid storage chamber 103 through the liquid channel T1.

[0135] In the examples of Figures 15-17 , unlike the examples of Figures 1-13 , by setting a reasonable axial distance of the liquid-conducting element 111, the port at one end of the through-hole 109 is covered by the liquid-conducting element 111, while the port at one end of the through-hole 110 may not be completely covered by the liquid-conducting element 111, or may be partially covered by the liquid-conducting element 111, but may be covered by the liquid adsorption element formed by the combination of the liquid-conducting element 111 and the liquid storage medium 103a. To prevent the air channel T2 from being blocked, a certain gap J1 may be provided between the wall defining the liquid storage chamber 103 and the outer surface of the liquid storage medium 103a. The air portion of the liquid storage chamber 103 can be connected to the external air, so that the air in the liquid storage chamber 103 can enter the gap J1 between the wall of the liquid storage chamber 103 and the outer surface of the liquid storage medium 103a through the notch 103a1 on the liquid storage medium 103a, and replenish air to the liquid storage chamber 202 through the air channel T2. Alternatively, it is also feasible to not provide the notch groove 103a1 and to achieve air communication by defining a gap between the wall of the liquid storage cavity 103 and the outer surface of the liquid storage medium 103a so as to communicate with the air portion of the liquid storage cavity 103.

[0136] Figures 18 to 21 show an electronic atomization device 100 and a liquid storage component 200 provided in another embodiment of the present application. In the examples of Figures 18 to 21 , the components with the same reference numerals and their descriptions can refer to the examples of Figures 1 to 13 .

[0137] In the examples of Figures 18 to 21 , the liquid adsorption element includes a liquid storage medium 103a, but no liquid conducting element 111 is provided; alternatively, the liquid conducting element 111 and the liquid storage medium 103a are filled in the liquid storage cavity 103 as an integrated liquid adsorption element.

[0138] 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 FIG20 : 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.

[0139] The liquid storage medium 103a is made of, for example, a fiber material or a porous material, and the liquid storage chamber 103 is filled with fiber cotton. The liquid storage medium 103a is used to absorb and retain the first liquid matrix and provide the first liquid matrix to the atomization component 104. After the liquid storage medium 103a reaches a saturated state after injection, the content of the liquid matrix in the liquid storage medium 103a is between 0.1ml and 2ml, for example, 0.5ml, 0.8ml, 1ml, 1.5ml or 2ml, etc. As shown in Figure 20, after the liquid storage medium 103a adsorbs the first liquid matrix and approaches saturation, the liquid storage chamber 103 can be divided into two parts with the end surface of the liquid storage medium 103a as the dividing interface. The part of the space inside the liquid storage chamber 103 not occupied by the liquid storage medium 103a is the air part, and the other part of the space occupied by the liquid storage medium 103a can be regarded as the liquid matrix part.

[0140] In the examples of Figures 18-21, the atomizing assembly 104 includes a liquid delivery unit and a heating element.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] In the examples of Figures 18 to 21, the lower end of the air flow channel 105 is connected to the air inlet, and the air inlet can be provided on the side wall 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 air flow in the air flow channel 105). The liquid storage chamber 103 is arranged around at least part of the air flow channel 105. The atomizer assembly 104 is arranged in the air flow channel 105, or the atomizer assembly 104 is configured as a tubular structure, and its internal hollow portion defines a portion of the air flow channel 105. A liquid hole is provided on the wall forming the air flow channel 105 to connect the liquid storage chamber 103 and the atomizer assembly 104, so that the liquid matrix in the liquid storage chamber 103 can be transferred to the atomizer assembly 104 and atomized.

[0145] In the examples of Figures 18-21 , 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 will be appreciated 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 for air and the other for the liquid matrix. This can be understood with reference to Figure 20 . Typically, liquid storage medium is not provided in liquid storage chamber 202.

[0146] In the examples of Figures 18 to 21, when the shell assembly 201 is connected to the shell assembly 101, the air portion of the liquid storage chamber 103 is connected to the air portion of the liquid storage chamber 202, and the liquid matrix portion of the liquid storage chamber 103 is connected to the liquid matrix portion of the liquid storage chamber 202.

[0147] In the examples of Figures 18 to 21 , one end of the through-hole 110 can be directly connected to the air portion of the liquid storage chamber 103. In another example, one end of the through-hole 110 can be connected to the air portion outside the liquid storage medium 103a. In a specific implementation, one end of the through-hole 110 can be connected to the air portion of the liquid storage chamber 103 through a gap between the liquid storage medium 103a and the wall defining the liquid storage chamber 103. For example, the inner surface of the wall defining the liquid storage chamber 103 has a protrusion, which abuts the outer surface of the liquid storage medium 103a, thereby forming a gap between the liquid storage medium 103a and the wall defining the liquid storage chamber 103, thereby allowing the through-hole 110 to communicate with the air portion of the liquid storage chamber 103. Alternatively, one end of the through-hole 110 passes through the liquid storage medium 103a and then extends to the air portion of the liquid storage chamber 103 (i.e., disposed near the suction nozzle 102), thereby communicating with the air portion of the liquid storage chamber 103. As can be seen from FIG. 18 , FIG. 19 and FIG. 21 , one end of the through hole 110 is covered by the liquid storage medium 103 a , while one end of the through hole 109 is not completely covered by the liquid storage medium 103 a or is partially covered by the liquid storage medium 103 a .

[0148] In the examples of Figures 18 to 21, the air channel T2 is arranged adjacent to the liquid channel T1. The port T1a at one end of the liquid channel and the port T2a at one end of the air channel are spaced apart along the axial direction of the electronic atomization device 100 or the liquid storage chamber 103, and the port T2a of the air channel is located above the port T1a of the liquid channel. In some examples, along the axial direction of the electronic atomization device 100, the port T1a of the liquid channel and the port T2a of the air channel are both arranged close to the bottom of the liquid storage chamber 103, that is, both are arranged away from the nozzle 102; in the axial direction of the electronic atomization device 100, the port T1a of the liquid channel is further away from the nozzle 102 of the electronic atomization device 100 than the port T2a of the air channel.

[0149] In the examples of Figures 18-21 , when the liquid medium 103a absorbs the liquid matrix, the air channel T2 may be blocked by the liquid matrix retained in the liquid medium 103a. For example, as shown in Figure 21 , when the level of the liquid matrix absorbed by the liquid medium 103a reaches the schematic line Y in the figure (the schematic line Y can be a horizontal line or a non-horizontal line), the port T2a of the through hole 110 located at one end of the liquid storage chamber 103 is blocked, and the gap between the liquid storage medium 103a and the through hole 110 is also blocked by the liquid matrix seeping from the liquid storage medium 103a, making it impossible for air to be exchanged between the liquid storage chamber 103 and the liquid storage chamber 202 through the air channel T2. The air pressure difference between the two causes the liquid storage chamber 202 to gradually reduce or even stop replenishing the liquid matrix to the liquid storage chamber 103.

[0150] When the electronic atomization device 100 is sucked (the liquid matrix in the liquid storage medium 103a is consumed) and the liquid matrix level schematic line Y gradually decreases, the liquid matrix blocked in the air channel T2 and the above-mentioned gap will also be re-absorbed by the liquid storage medium 103a. When the liquid matrix level drops to a position below the through hole 110, the air in the through hole 110 and the liquid storage chamber 103 is partially connected, and the air connection between the liquid storage chamber 103 and the liquid storage chamber 202 is restored through the air channel T2, and the liquid storage chamber 202 resumes replenishing the liquid matrix to the liquid storage chamber 103 (the dotted arrows in the figure, one is the air flow direction of the air channel T2, and the other is the liquid matrix flow direction of the liquid channel T1). In this way, the liquid matrix retained in the liquid storage medium 103a alternately blocks and opens the air channel T2, so that the liquid storage chamber 202 can automatically and quantitatively provide the liquid matrix to the atomizer component 104, and when the liquid matrix near the atomizer component 104 is consumed and reduced, the liquid supply can be automatically restored, thereby improving the user's puffing experience and avoiding adverse risks such as liquid leakage and abnormal puffing noise caused by excessive liquid matrix provided to the atomizer component 104.

[0151] When the electronic atomization device 100 is not in use, the air portion of the air channel T2 and the liquid storage chamber 103 is blocked by the liquid matrix retained in the liquid storage medium 103a; when the electronic atomization device 100 is in the inhaled state or during the lag period after inhalation, the air portion of the air channel T2 and the liquid storage chamber 103 is connected.

[0152] In the examples of Figures 18-21 , when the amount of liquid matrix absorbed by the liquid storage medium 103a reaches a first preset amount, the port of the through hole 110 at one end of the liquid storage chamber 103 is blocked. When the amount of liquid matrix in the liquid storage medium 103a is consumed by a second preset amount, the port of the through hole 110 at one end of the liquid storage chamber 103 is opened. The first preset amount and the second preset amount are substantially the same. Substantially the same means that the difference between the two is within 20 μL, or within 15 μL, or within 10 μL, or within 6 μL, or within 4 μL.

[0153] In the examples of Figures 18 to 21, if the distance between the port T1a at one end of the through hole 109 and the port T2a at one end of the through hole 110 is too large, it is easy to cause an excessive amount of liquid matrix to be provided to the atomizer assembly 104. Generally, the port at one end of the through hole 109 and the port at one end of the through hole 110 are both located close to the atomizer assembly 104 (along the horizontal direction of the liquid storage chamber 103). The longitudinal distance between the port at one end of the through hole 109 and the port at one end of the through hole 110 is between 1 mm and 8 mm, so that the liquid matrix provided from the liquid storage chamber 202 is basically maintained in the area around the atomizer assembly 104. Therefore, in product design, the amount of liquid matrix provided to the atomizer assembly 104 can be appropriately controlled by adjusting the spacing between the through hole 109 and the through hole 110. In a specific implementation, the above spacing distance may be between 2 mm and 8 mm, or between 2 mm and 6 mm, or between 2 mm and 4 mm.

[0154] In the examples of Figures 18 to 21, the distance between the port T1a at one end of the liquid storage chamber 103 where the through hole 109 is located or the port T2a at one end of the liquid storage chamber 103 where the through hole 110 is located and the atomizer assembly 104 in the horizontal direction of the liquid storage chamber 103 is between 2 and 8 mm. In specific implementations, it can be between 2 mm and 6 mm, or between 2 mm and 5 mm, or between 2 mm and 4 mm.

[0155] In the examples of Figures 18-21 , the axial distance between the through hole 110 at one end T2a of the liquid storage chamber 103 and the bottom of the liquid storage chamber 103 is between 2 mm and 10 mm. In specific implementations, the distance can be between 2 mm and 8 mm, or between 2 mm and 6 mm, or between 2 mm and 4 mm, or between 2 mm and 3 mm. This distance is at least one factor that affects the amount of liquid matrix provided to the atomizer assembly 104.

[0156] 22 and 23 show an electronic atomization device 100 and a liquid storage component 200 provided in yet another embodiment of the present application. In the examples of FIG22 and FIG23 , the components with the same reference numerals and their descriptions can refer to the aforementioned examples.

[0157] Unlike the previous examples, in the examples of Figures 22-23, 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.

[0158] Different from the above examples, in the example of FIG. 22 - FIG. 23 , the suction nozzle 102 is provided on the housing assembly 201 .

[0159] Unlike the above examples, the housing assembly 201 of the above examples does not have an air flow channel. In the examples of Figures 22-23, the air flow channel includes a first air flow channel 105a and a second air flow channel 105b. The first air flow channel 105a is arranged in the housing assembly 101, and the second air flow channel 105b is arranged in the housing assembly 201. When the housing assembly 201 is connected to the housing assembly 101, the first air flow channel 105a is communicated with the second air flow channel 105b to transmit the aerosol generated by the atomization assembly 104 (T3 in the figure is the air flow direction in the first air flow channel 105a and the second air flow channel 105b). Among them, the liquid storage chamber 103 is arranged around at least a portion of the first air flow channel 105a, and the liquid storage chamber 202 is arranged around at least a portion of the second air flow 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.

[0160] Unlike the previous example, in the example of Figures 22-23, 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 end of the electronic atomization device, while the liquid storage chamber 202 is arranged near the top end of the electronic atomization device.

[0161] Similar to the above example, a liquid storage medium 103 a is provided in the liquid storage cavity 103 , and the liquid storage medium 103 a is disposed on the sealing member 103 c .

[0162] Unlike the previous examples, in the examples of Figures 22-23 , one end of through-hole 109 communicates with the liquid storage chamber 103, while the other end of through-hole 109 protrudes from the top wall of housing assembly 101. One end of through-hole 110 communicates with the air portion of liquid storage chamber 103, while the other end of through-hole 110 protrudes from the top wall of housing assembly 101. Liquid storage medium 103a covers one end of through-hole 110 (the upper surface of liquid storage medium 103a maintains contact with the end surface of one end of through-hole 110, as shown in Figure D), while one end of through-hole 109 is not covered by liquid storage medium 103a. Alternatively, it is possible to cover one end of through-hole 109 with liquid storage medium 103a. In other alternative examples, the air duct forming through-hole 110 is inserted into liquid storage medium 103a, so that the air inlet port of through-hole 110 is covered by liquid storage medium 103a.

[0163] Unlike the previous example, in the example of Figures 22-23 , one end of through hole 201b4 communicates with the liquid matrix portion of liquid storage chamber 202, while the other end of through hole 201b4 protrudes from the bottom wall of housing assembly 201. One end of through hole 201b5 passes through liquid storage chamber 202 and communicates with the air portion of liquid storage chamber 202, while the other end of through hole 201b5 extends to the bottom wall of housing assembly 201.

[0164] Different from the above-mentioned examples, in the examples of Figures 22-23, when the shell assembly 201 is connected to the shell assembly 101, the other end of the through hole 201b4 extends into the through hole 109, thereby connecting the liquid matrix portion of the liquid storage chamber 103 with the liquid matrix portion of the liquid storage chamber 202 (T1 in the figure is the flow direction of the liquid matrix in the liquid channel); the other end of the through hole 110 extends into the through hole 201b5, thereby connecting the air portion of the liquid storage chamber 103 with the air portion of the liquid storage chamber 202.

[0165] Unlike the previous examples, in the examples of Figures 22-23, there are two through holes 110 and two through holes 201b5, both of which are spaced apart along the thickness direction of the electronic atomization device. Through multiple air channels, the air pressure of the liquid storage chamber 103 and the liquid storage chamber 202 can be better balanced.

[0166] Similar to the above example, when the liquid matrix absorbed by the liquid storage medium 103a reaches the schematic line Y in the figure, one end of the through hole 110 is blocked, and air cannot be communicated between the liquid storage chamber 103 and the liquid storage chamber 202 through the air channel T2. The accumulated air pressure difference prevents the liquid matrix from flowing from the liquid storage chamber 202 to the liquid storage chamber 103, thereby causing the liquid storage chamber 202 to reduce or even stop replenishing the liquid matrix to the liquid storage chamber 103. When the electronic atomization device 100 is sucked to consume the liquid matrix, the liquid matrix horizontal schematic line Y drops, and the liquid matrix blocked in the air channel will also be absorbed by the liquid storage medium 103a, thereby making the through hole 110 conductive, and the air between the liquid storage chamber 103 and the liquid storage chamber 202 is re-connected through the air channel T2. The air in the liquid storage chamber 103 can re-enter the through hole 110 through the pores inside the fiber material of the liquid storage medium 103a, and the liquid storage chamber 202 resumes replenishing the liquid matrix to the liquid storage chamber 103 (the dotted arrows in the figure, one is the air flow direction of the air channel, and the other is the liquid matrix flow direction of the liquid channel). Repeatedly, through the liquid storage medium, the liquid matrix can be automatically and quantitatively provided to the atomization component 104, thereby improving the user's suction experience.

[0167] Similar to the previous example, when the amount of liquid matrix absorbed by the liquid storage medium 103a reaches a first preset amount, the through hole 110 at one end of the liquid storage chamber 103 is blocked. When the amount of liquid matrix in the liquid storage medium 103a is consumed by a second preset amount, the through hole 110 is opened. The first preset amount and the second preset amount are substantially the same. Substantially the same means that the difference between the two is within 20 μL, or within 15 μL, or within 10 μL, or within 6 μL, or within 4 μL.

[0168] Similar to the above example, the axial distance between the through hole 110 located at one end of the liquid storage chamber 103 and the bottom of the liquid storage chamber 103 is between 5 mm and 20 mm. In a specific implementation, it can be between 5 mm and 15 mm, or between 5 mm and 10 mm. This distance is also at least one factor that affects the amount of liquid matrix provided to the atomizer assembly 104.

[0169] Similar to the above example, the housing assembly 101 further has a receiving cavity 108 for receiving part of the housing assembly 201. It is understandable that in other examples, the housing assembly 201 may also have a receiving cavity for receiving or accommodating at least part of the housing assembly 101.

[0170] 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.

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.
