Electronic atomization device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on February 26, 2024, with application number 202410211849.7 and entitled “Electronic Atomization Device,” the entire contents of which are incorporated herein by reference. Technical Field

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

[0004] An electronic atomization device is an electronic product that generates aerosols for users to inhale by atomizing a liquid matrix. 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] Due to various factors, such as cost, regulations, etc., the amount of liquid matrix stored inside the atomizer is generally 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 discarded directly. 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 larger capacity liquid storage component, thereby reducing the user's usage cost and improving the user's usage experience. However, the problem with this device is that the rate at which the liquid storage component replenishes the liquid matrix to the electronic atomization device is uncontrollable, and it is easy to have a fast liquid conduction rate and abnormal noise during suction.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 3 and 6 , 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] Referring primarily to Figures 3 and 4 , 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 and, therefore, communicates with the air outlet (the dotted arrows in Figures 3 and 4 indicate the direction of airflow in the airflow channel 105 ).

[0076] 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.

[0077] 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.

[0078] 7 and 8 , the sidewall of the connecting tube 105a is further 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 matrix.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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 controller, controls the operation of the battery cell 107, the heating element, etc. according to the electrical signal, for example, controlling 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.

[0084] 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.

[0085] 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.

[0086] 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, such as 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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 .

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] In this case, through-holes 201b4, 201d2, and 109 together define a liquid channel (first channel), 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 of the liquid channel communicates with the liquid storage chamber 202. Through-holes 201b5, 201d3, and 110 together define an air channel (second channel), which provides an air path for air exchange between the liquid storage chamber 103 and the liquid storage chamber 202. One end of the air channel communicates with the air portion of the liquid storage chamber 103, while the other end of the air channel communicates with the air portion of the liquid storage chamber 202. The air passage 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 to the liquid storage chamber 103, promptly replenishing the consumed liquid matrix to 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.

[0104] 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.

[0105] In the above embodiment, the material of the liquid-conducting element 111 can be the same as or different from that of the liquid storage medium 103a. The density of the liquid-conducting element 111 is greater than that of the liquid storage medium 103a. This ensures that the liquid-conducting element 111 can effectively absorb the liquid matrix in the liquid channel, allowing the liquid matrix in the liquid-conducting element 111 to be smoothly transferred to the liquid storage medium 103a. Furthermore, the liquid-conducting element 111 can reduce the oversaturation of the liquid storage medium 103a, thereby reducing the probability of liquid matrix leakage.

[0106] 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 between the wall defining the liquid storage chamber 103 and the outer surface of the liquid-conducting element 111, so that air can pass through the gap between the wall defining the liquid storage chamber 103 and the outer surface of the liquid-conducting element 111, flow to the notch groove 103a1, and then communicate with the air part of the liquid storage chamber 103 to achieve air exchange.

[0107] 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. 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).

[0108] 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. In other words, this helps to slow the rate at which the liquid matrix reaches the liquid guide element 104a.

[0109] 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.

[0110] 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 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 near the through hole 201d3, and the other end extends to the left side wall of the sealing member 201d.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] It should be noted that there may be multiple liquid storage components 200 .

[0116] It should be noted that in other examples, it is also feasible that the electronic atomization device cannot be used and smoked before the housing assembly 201 is connected to the housing assembly 101. That is, the electronic atomization device can be used and smoked 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.

[0117] It should be noted that the aforementioned housing assembly 201 does not have an airflow channel. 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.

[0118] It should be noted that, in other examples, when the housing assembly 201 is connected to the housing assembly 101 , it is also feasible that the liquid storage cavity 202 is arranged to surround at least a portion of the liquid storage cavity 103 .

[0119] 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.

[0120] 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.

[0121] As shown in FIG13 , 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.

[0122] Figures 14-19 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 14-19, components with the same reference numerals and their descriptions can refer to the examples and descriptions of Figures 1-12. It should be noted that in the examples of Figures 14-19, the wall defining the through hole 201b5 is the same as that in the example of Figure 13. It is understood that the structure of the examples of Figures 1-12 can also be used.

[0123] In the example of Figures 14-19 , unlike the example of Figures 1-12 , the outer surface of the wall defining through-hole 109 further has a protrusion 109a, and the outer surface of the wall defining through-hole 110 further has a protrusion 110a. Correspondingly, the inner surface of seal 201d further has a retaining groove 201d6 and a retaining groove 201d7. When housing assembly 201 is connected to housing assembly 101, protrusion 109a is retained in retaining groove 201d6, and protrusion 110a is retained in retaining groove 201d7. Thus, when housing assembly 201 is disassembled from housing assembly 101, seal 201d can be driven and moved outward, thereby returning to the state in which housing assembly 201 is disconnected from housing assembly 101, i.e., the position (second position) in which through-hole 201b5 is closed, preventing leakage of the liquid matrix. Specifically, through-hole 201b4 is connected to through-hole 201d2; while 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. This state is shown in Figure 15. This arrangement allows the liquid storage component 200 to be removably used.

[0124] In other variations, the connection can be realized by only one protrusion and one corresponding slot. Alternatively, the sealing member 201d and the wall defining the through hole 109 or the through hole 110 can be connected in other ways.

[0125] In another variation, an elastic member, such as a compression spring, may be disposed within the receiving cavity 201b3 of the bottom cover 201b. One end of the elastic member is secured within the receiving cavity 201b3, and the other end is connected to the sealing member 201d, for example, by abutting or fixed connection. In this manner, when the housing assembly 201 is connected to the housing assembly 101, the elastic member can be compressed. When the housing assembly 201 is disconnected from the housing assembly 101, the sealing member 201d can move outward under the elastic force of the elastic member, thereby returning to the state in which the housing assembly 201 and the housing assembly 101 were disconnected.

[0126] In a further embodiment, a blocking member 201e is further provided on the bottom cover 201b. When the sealing member 201d is driven to move outward, the blocking member 201e can prevent the sealing member 201d from falling off from the receiving cavity 201b3.

[0127] It should be noted that in the examples of Figures 14-19, the sealing member 201d moves between a first position and a second position to open or close the liquid passage. In other examples, the sealing member 201d may move between the first position and the second position to open or close only the air passage. It is further understood that the sealing member 201d may simultaneously open or close both the air passage and the liquid passage.

[0128] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of this application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to be additional limitations on the content of this application. The purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and comprehensive. In addition, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of this application; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
