Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, and in particular to a device body and an electronic atomization device. BACKGROUND

[0002] Due to various factors such as cost, regulation, etc., the amount of liquid substrate stored inside an electronic atomization device is generally small. When the liquid substrate is consumed, the device can be refilled, the atomizer replaced, or the device discarded. The above methods are inconvenient for the user, reducing the user's experience, and increasing the user's cost.

[0003] One solution is to use a larger capacity liquid storage component to supplement the liquid substrate to the device body of the electronic atomization device, thereby reducing the user's cost and improving the user's experience. However, this solution has a problem that when the device body is placed horizontally, air bubbles tend to accumulate in the liquid channel between the liquid storage component and the device body. Therefore, when the device body is placed vertically from the horizontal position, the liquid channel is easily blocked by air bubbles, so that the liquid substrate in the liquid storage component cannot be supplemented to the device body. UTILITY MODEL CONTENT

[0004] The present application aims to provide a device body and an electronic atomization device to solve the problem that the liquid channel between the liquid storage component and the device body is easily blocked by air bubbles.

[0010] In one example, the length of the second section is less than the length of the first section.

[0011] In an example, the length of the second section is between 0.5mm and 1.2mm; and / or the length of the first section is between 8mm and 10mm.

[0012] In an example, one of the first housing and the second housing is provided with a connector, and the other is provided with a socket; the connector is plugged into the socket to establish the connection passage.

[0013] A merging cavity and a first through-hole are defined in the connector, the merging cavity constitutes a first section of the connection passage, and the first through-hole constitutes one second section of the connection passage.

[0014] In an example, the connector is provided on the first housing, one end of the first through-hole is in communication with the first liquid storage cavity, the other end of the first through-hole is in communication with the merging cavity, and the merging cavity is also in communication with outside of the first housing.

[0015] In an example, the socket is provided on the second housing, one end of the socket is in communication with the second liquid storage cavity, and the other end of the socket is in communication with outside of the second housing.

[0039] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used in the present specification have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the present specification are only for the purpose of describing specific embodiments of the present application and are not intended to limit the present application.

[0040] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0041] As used herein, when an element is referred to as being "on" another element, it can be directly on the other element or one or more intervening elements can be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or one or more intervening elements can be present.

[0042] As used herein, the terms "upper", "lower", "left", "right", "inner", "outer" and similar expressions are for illustrative purposes only.

[0043] As used herein, the terms "first", "second", and the like are used to distinguish one element from another, and are not necessarily used to describe a relative importance or specific order or sequence of, or preference for, the features being described.

[0044] As Figures 1-6 As shown in FIG. 1, an electronic atomization device provided by an embodiment of the present application includes a device body 100 and a liquid storage component 200, and the number of liquid storage components 200 can be one or more.

[0045] The device body 100 includes a first housing 101, which can be composed of multiple components, such as a main housing 101a and a top cover 101b disposed at the top end of the main housing 101a, or the first housing 101 can be integrally formed.

[0046] The top of the first housing 101 is provided with a suction nozzle 102. The suction nozzle 102 can be integrally formed with the first housing 101 or formed separately. The suction nozzle 102 is used for the user to inhale the aerosol generated by atomization.

[0047] A reservoir 103 for storing a first liquid matrix is ​​formed within the first housing 101. The first liquid matrix may be a liquid containing tobacco-containing substances, including volatile tobacco aroma components, or a liquid containing non-tobacco substances. For example, the liquid matrix may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavoring components. Flavorings may include components capable of providing the user with a variety of fragrances or flavors. Vitamin mixtures may be substances containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. In addition, the first liquid matrix may include aerosol forming agents such as glycerin and propylene glycol.

[0048] The liquid storage chamber 103 is provided with a liquid storage medium 103a, the upper end of the liquid storage chamber 103 is provided with a sealing element 103b, and the lower end of the liquid storage chamber 103 is provided with a sealing element 103c. The upper and lower ends of the liquid storage chamber 103 are sealed by the sealing elements 103b and 103c.

[0049] The storage medium 103a is made of, for example, a fibrous or porous material. Figure 7 As shown, the liquid storage medium 103a has a generally tubular structure. The liquid storage medium 103a adsorbs and retains the first liquid matrix and provides it to the atomizing core 104. After liquid injection, when the liquid storage medium 103a reaches saturation, the content of the liquid matrix in the liquid storage medium 103a is between 0.1 ml and 2 ml, for example, 0.5 ml, 0.8 ml, 1 ml, 1.5 ml, or 2 ml, etc. The space between the upper end face of the liquid storage medium 103a and the sealing element 103b defines an air portion.

[0050] The first housing 101 is provided with an atomizing core 104, which is used to atomize the liquid matrix to generate an aerosol.

[0051] like Figure 8 As shown, the atomizing core 104 includes a liquid guiding element 104a and a heating element 104b. The liquid guiding 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 an electric current supply and transfers heat to the liquid matrix in contact with the heating element 104b to heat the liquid matrix, thereby generating an aerosol.

[0052] The liquid-conducting element 104a is constructed as a tubular structure; 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 fibrous material, such as cotton fibers, non-woven fabric, or sponge. Alternatively, in other examples, the liquid-conducting element 104a can also be a rigid porous body, such as porous ceramics or porous glass. The outer surface of the liquid-conducting element 104a has radially outward protrusions 104a1.

[0053] The heating element 104b is disposed near the inner surface of the liquid-conducting element 104a, and can be attached to 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 temperature coefficient of resistance characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In one example, the heating element 104b can be wound from 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 of the device body 100. Conductive leads 104c and conductive leads 104d are welded or arranged at both ends of the heating element 104b for guiding current in the heating element 104b. In other examples, the heating element 104b can be configured as a structure wound around the liquid-conducting element 104a.

[0054] The first housing 101 also has an airflow channel 105 to transport the aerosol generated by the atomizing core 104 to the mouthpiece 102 for inhalation by the user. The lower end of the airflow channel 105 is connected to the air inlet, which can be located on the bottom wall of the first housing 101; the upper end of the airflow channel 105 is connected to the mouthpiece 102, i.e., connected to the air outlet (see the dashed arrow S1 in the figure for details).

[0055] like Figure 9 As shown, a connecting pipe 105a is provided inside the first housing 101, and the hollow portion inside the connecting pipe 105a defines a partial airflow channel 105. The connecting pipe 105a extends along the axial direction of the liquid storage chamber 103. The upper end of the connecting pipe 105a is connected to the sealing member 103b, and the lower end of the connecting pipe 105a is connected to the sealing member 103c. The connecting pipe 105a is preferably made of a relatively thin rigid material, such as glass fiber or stainless steel.

[0056] In a preferred embodiment, the liquid storage medium 103a is fitted 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 fitted on the connecting tube 105a. The atomizing core 104 is arranged in the connecting tube 105a. The atomizing core 104 is coaxially arranged with the connecting tube 105a. The side wall of the connecting tube 105a further has a liquid guide opening 105a1 arranged near the lower end of the connecting tube 105a, the liquid storage medium 103a covers the liquid guide opening 105a1, and a portion of the liquid guide element 104a is exposed in the liquid storage cavity 103 through the liquid guide opening 105a1, so that the portion of the liquid guide element 104a is arranged near the liquid storage medium 103a and keeps contact with the liquid storage medium 103a, and thus the liquid matrix in the liquid storage cavity 103 flows into the atomizing core 104 through the liquid guide opening 105a1, i.e. is sucked by the liquid guide element 104a, and is atomized by the heating element 104b to generate the aerosol that can be inhaled.

[0057] The side wall of the connecting tube 105a further has a notch groove 105a2 extending from the lower end of the connecting tube 105a towards the upper end of the connecting tube 105a. The protruding portion 104a1 of the liquid guide element 104a extends into the notch groove 105a2, so as to be exposed in the liquid storage cavity 103. After assembly, the liquid storage medium 103a keeps contact with the portion of the protruding portion 104a1, so as to facilitate the liquid guide element 104a to suck the liquid matrix.

[0058] The first shell 101 further has an electric circuit 106, which can control the overall operation of the device body 100. In detail, the electric circuit 106 not only controls the operation of the battery 107 and the atomizing core 104, but also controls the operation of other elements in the device body 100. In addition, the electric circuit 106 can determine whether the device body 100 can operate by checking the state of the components of the device body 100.

[0059] The electric circuit 106 includes at least one control unit. The control unit can include a logic gate array, or can include a combination of a general-purpose microcontroller and a memory for storing a program executable in the microcontroller. In addition, those skilled in the art should understand that the electric circuit 106 can include another type of hardware.

[0060] The battery 107 provides power for operating the device body 100. For example, the battery 107 can provide power for the heating element to heat, and can provide power required for operating the electric circuit 106. In addition, the battery 107 can provide power required for operating other components provided in the device body 100.

[0061] Cell 107 can be a rechargeable battery or a disposable battery. Cell 107 can be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, cell 107 can be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery.

[0062] It should be noted that only components relevant to this embodiment are shown in the figures. Those skilled in the art will understand that the device body 100 may also include, in addition to... Figures 1-6 Other common components besides those shown. For example, a suction detector may also be provided inside the first housing 101 to detect the user's suction action and generate a corresponding electrical signal, i.e., to detect whether the main body 100 of the device is being suctioned, so that the circuit 106, such as the control unit, controls the operation of the battery cell 107, heating element 104b, etc., according to the electrical signal. For example, it controls the battery cell 107 to provide power to the heating element 104b so that the heating element 104b heats the atomized liquid matrix. The suction detector can be a common pressure sensor, differential pressure sensor, airflow sensor, etc. The suction detector is connected to the airflow channel 105, so that it can sense changes in the suction airflow when the user is suctioning.

[0063] It should also be noted that, in Figures 1-6 In one example, the aforementioned components are integrally formed, and the main body 100 of the device is a typical one-piece device. In other examples, the main body 100 of the device includes an atomizer and a power supply assembly detachably connected to the atomizer. The atomizer is usually referred to as a cartridge, and the power supply assembly is usually referred to as a device. The circuit 106, the battery 107, and the vaping detector are located in the power supply assembly. It is also feasible for the mouthpiece 102, the liquid storage chamber 103, and the atomizing core 104 to be located in the atomizer.

[0064] Please combine Figures 11-13 To understand, the liquid storage component 200 includes a second housing 201, which may be composed of multiple components, such as a main housing 201a, a bottom cover 201b, a seal 201c, and a seal 201d.

[0065] The main housing 201a is connected with the bottom cover 201b. In a preferred embodiment, the main housing 201a is detachably connected with the bottom cover 201b, for example, snap connection. Part of the bottom cover 201b extends into the main housing 201a. The main housing 201a and the bottom cover 201b together define a liquid storage cavity 202 for storing the second liquid substrate. In a further embodiment, the bottom cover 201b is provided with a liquid injection port 201b1 through which the second liquid substrate can be injected into the liquid storage cavity 202; the liquid injection port 201b1 can be sealed by a sealing member or by other means, which are not limited in the present application. A sealing member 201c is arranged between the bottom cover 201b and the main housing 201a to prevent the second liquid substrate from leaking from the gap between the bottom cover 201b and the main housing 201a. In a preferred embodiment, the outer surface of the bottom cover 201b is provided with a groove 201b2, and the sealing member 201c is annular and at least partially received in the groove 201b2, thereby achieving sealing between the bottom cover 201b and the main housing 201a.

[0066] Similar to the first liquid substrate, the second liquid substrate can be a liquid including a tobacco-containing substance containing volatile tobacco flavor components, or a liquid including a non-tobacco substance. For example, the liquid substrate can include water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture. The flavor can include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent can include components capable of providing a user with a variety of flavors or tastes. The vitamin mixture can be a substance mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the second liquid substrate can include an aerosol forming agent such as glycerin and propylene glycol.

[0067] It should be noted that the components or properties of the second liquid substrate can be different from or the same as those of the first liquid substrate. For example, in some examples, the second liquid substrate and the first liquid substrate are different in composition or concentration. For example, in other examples, the second liquid substrate and the first liquid substrate are exactly the same in composition, the second liquid substrate can be part of a certain liquid formulation, and the first liquid substrate can be another part of the certain liquid formulation. The second liquid substrate can be introduced into the liquid storage cavity 103 as a supplement to the first liquid substrate, thereby increasing the number of puffs of the electronic atomization device.

[0068] The volume of the liquid storage cavity 202 is greater than that of the liquid storage cavity 103. Generally, the capacity of the second liquid medium stored in the liquid storage cavity 202 is between 2ml and 10ml, such as 2ml, 4ml, 5ml, 6ml, 8ml, 10ml, etc. It can be understood that the volume of the liquid storage cavity 202 is slightly greater than the capacity of the second liquid medium stored. In this way, after the second liquid medium is stored in the liquid storage cavity 202, it can be divided into two parts, one part is an air part, and the other part is a liquid medium part. Generally, no liquid storage medium is arranged in the liquid storage cavity 202.

[0069] The liquid storage component 200 is independent of the device main body 100, for example, the product is in a packaged state or an unused state, the liquid storage component 200 is separated from the device main body 100, and the user can assemble the liquid storage component 200 on the device main body 100 before use. In an example, the liquid storage component 200 is detachably connected with the device main body 100, that is, the second shell 201 is detachably connected with the first shell 101, for example, snap connection, magnetic connection, etc. In an example, the liquid storage component 200 is not re-detachable once connected with the device main body 100.

[0070] The first shell 101 is also provided with a receiving cavity 108 for receiving or accommodating at least part of the second shell 201. Specifically, the shape of the receiving cavity 108 is adapted to the shape of the second shell 201, and the receiving cavity 108 is a notch groove through part of the left side wall and part of the top wall of the first shell 101, and the second shell 201 can be assembled on the first shell 101 from the left side of the first shell 101. The inner wall of the receiving cavity 108 is provided with a clamping buckle 108a, and the outer wall of the second shell 201 is provided with a clamping hole 201a1, and the clamping buckle 108a and the clamping hole 201a1 are matched to realize the snap connection of the second shell 201 and the first shell 101. It should be noted that the number of clamping buckles 108a and clamping holes 201a1 is not limited here, and the position can be adjusted as needed. After the second shell 201 is connected with the first shell 101, the outer shell of the device main body 100 is jointly defined. It can be understood that the connection mode of the second shell 201 and the first shell 101 is not limited to the above case.

[0071] In an example, a guide mechanism can be provided between the device main body 100 and the liquid storage component 200, so as to facilitate the assembly of the second shell 201 on the first shell 101 in the direction from the left side of the first shell 101 to the right side of the first shell 101. For example, a sliding block 108b is arranged on the inner wall of the receiving cavity 108, and a sliding groove 201a2 is arranged on the second shell 201 of the liquid storage component 200, and the sliding block 108b can slide in the sliding groove 201a2, so as to assemble the second shell 201 on the first shell 101.

[0072] When the second shell 201 is connected with the first shell 101, the liquid storage cavity 103 and the liquid storage cavity 202 are arranged in sequence along the width direction of the electronic atomization device. The liquid storage cavity 103 is arranged close to the right side of the electronic atomization device, and the liquid storage cavity 202 is arranged close to the left side of the electronic atomization device. It can be understood that the arrangement of the liquid storage cavity 103 and the liquid storage cavity 202 is not limited to the above case.

[0073] In an example, when the second shell 201 is connected with the first shell 101, a connection channel for the flow of liquid substrate and / or air can be established between the first liquid storage cavity 103 and the second liquid storage cavity 202. The connection channel includes a first section adjacent to and communicating with the second liquid storage cavity 202, at least one second section through the first section, the second section being adjacent to and communicating with the first liquid storage cavity 103, and the cross-sectional area of the first section being greater than that of the second section.

[0074] Specifically, the first shell 101 is provided with a connector 109, and the second shell 201 is provided with a plug-in port 201b3.

[0075] The connector 109 is located in the accommodation cavity 108, and one end of the connector 109 protrudes from the cavity wall of the accommodation cavity 108, for example, the right cavity wall of the accommodation cavity 108. The connector 109 extends in the width direction of the first shell 101 towards the direction away from the right cavity wall of the accommodation cavity 108. The connector 109 is formed with a confluence cavity 109a, a second through hole 109b and a first through hole 109c. The second through hole 109b and the first through hole 109c are arranged in the length direction of the first shell 101, that is, there is a height difference between the second through hole 109b and the first through hole 109c, for example, separated by a partition 109d. The second through hole 109b and the first through hole 109c are arranged close to the first liquid storage cavity 103, and the confluence cavity 109a is arranged away from the first liquid storage cavity 103 relative to the second through hole 109b or the first through hole 109c, or the confluence cavity 109a is arranged close to the outside of the first shell 101. One end of the second through hole 109b communicates with the first liquid storage cavity 103, and the other end of the second through hole 109b communicates with the confluence cavity 109a; one end of the first through hole 109c also communicates with the first liquid storage cavity 103, and the other end of the first through hole 109c also communicates with the confluence cavity 109a. The confluence cavity 109a also communicates with the outside of the first shell 101.

[0076] One end of the plug-in port 201b3 is arranged close to the bottom of the second liquid storage cavity 202 and communicates with the second liquid storage cavity 202, and the other end of the plug-in port 201b3 communicates with the outside of the second shell 201.

[0077] When the second housing 201 is connected to the first housing 101, the joint 109 is inserted into the insertion port 201b3, thereby connecting the first liquid storage cavity 103 and the second liquid storage cavity 202 and establishing a connecting passage for the liquid medium and / or air to flow between the first liquid storage cavity 103 and the second liquid storage cavity 202. The confluence cavity 109a defines a first section of the connecting passage, the first through hole 109c defines a second section of the connecting passage, and the second through hole 109b defines another second section of the connecting passage.

[0078] In this way, the liquid medium in the second liquid storage cavity 202 can flow into the confluence cavity 109a and then be introduced or supplemented into the first liquid storage cavity 103 through the first through hole 109c. When the liquid medium in the second liquid storage cavity 202 is reduced, the air in the first liquid storage cavity 103 can be introduced or flowed into the second liquid storage cavity 202 through the second through hole 109b and the confluence cavity 109a in sequence, thereby balancing the air pressure difference between the first liquid storage cavity 103 and the second liquid storage cavity 202, so that the second liquid medium stored in the second liquid storage cavity 202 can flow smoothly to the first liquid storage cavity 103 and supplement the consumed liquid medium in the first liquid storage cavity 103 in time.

[0079] As can be seen from the above, the first through hole 109c defines a liquid passage, and the second through hole 109b defines an air passage. It can be understood that the first through hole 109c can define a liquid passage together with other components, and the second through hole 109b or the confluence cavity 109a is similar.

[0080] The length of the liquid passage (the distance of the liquid medium flowing in the liquid passage), for example, the extension length of the first through hole 109c along the width direction of the first housing 101, is relatively short. Generally, the length of the liquid passage is between 0.5mm and 1.2mm, or between 0.6mm and 1.2mm, or between 0.7mm and 1.2mm, or between 0.7mm and 1mm, or between 0.7mm and 0.9mm. The length of the liquid passage is set to be relatively short, which is beneficial to supplement the liquid medium in the second liquid storage cavity 202 to the first liquid storage cavity 103. The length of the air passage, for example, the extension length of the second through hole 109b along the width direction of the first housing 101, is also set to be relatively short, and the length of the air passage can be set according to the length of the liquid passage described above.

[0081] The length of the first section or the confluence cavity 109a (the distance through which the liquid medium flows in the confluence cavity or the confluence cavity 109a), for example, the extension length of the confluence cavity 109a along the width direction of the first shell 101, is much greater than the length of the liquid channel or the air channel, that is, the length of the second section is less than the length of the first section. Generally, the length of the first section or the confluence cavity 109a is between 8mm and 10mm, or between 8mm and 9mm, or between 8mm and 8.5mm. The cross-sectional area of the confluence cavity 109a (the cross-sectional area intersected with a plane extending along the length direction and the thickness direction of the electronic atomization device) is also much greater than the cross-sectional area of the liquid channel or the air channel.

[0082] By arranging the confluence cavity 109a, on the one hand, the liquid medium in the second liquid storage cavity 202 can flow into the joint 109, and then be supplemented to the first liquid storage cavity 103 through the first through hole 109c; on the other hand, since the bubbles are prone to accumulate in the first through hole 109c when the electronic atomization device is placed horizontally, when the electronic atomization device is rotated from horizontal placement to vertical placement, the bubbles accumulated in the first through hole 109c are prone to escape through the confluence cavity 109a, thereby avoiding the liquid channel from being blocked. In addition, as can be seen from the figure, the extension length of the joint 109 is greater than or equal to the extension length of the plug-in port 201b3, so that the end of the joint 109 can be close to or enter the second liquid storage cavity 202, thereby shortening the path length of the liquid flow or the air flow.

[0083] The sealing member 201d is at least partially accommodated in the plug-in port 201b3. The sealing member 201d has a through hole 201d1 therein, and a puncturable sealing film 201d2 is arranged in the through hole 201d1. When the second shell 201 is connected with the first shell 101, the joint 109 can extend into the through hole 201d1 and puncture the sealing film 201d2, thereby connecting the first liquid storage cavity 103 and the second liquid storage cavity 202. After the second shell 201 is connected with the first shell 101, the sealing member 201d is located between the outer wall of the joint 109 and the inner wall of the plug-in port 201b3, thereby forming a seal.

[0084] In further embodiments, the liquid storage cavity 103 is further provided with a liquid guide element 110. As shown in FIG. 6, the liquid guide element 110 is arranged in the liquid storage cavity 103 and is located between the first liquid storage cavity 103 and the second liquid storage cavity 202. The liquid guide element 110 is arranged to guide the liquid medium in the second liquid storage cavity 202 to flow into the first liquid storage cavity 103. Figure 10As shown, the liquid guiding element 110 is substantially in a tubular structure. The liquid guiding element 110 and the liquid storage medium 103a are arranged along the axial direction of the liquid storage cavity 103 in sequence. The liquid storage medium 103a is arranged close to the second through hole 109b, and the liquid guiding element 110 is arranged close to the first through hole 109c, i.e., the liquid guiding element 110 is in communication with the liquid passage. The first through hole 109c is covered by the liquid guiding element 110. The upper surface of the liquid guiding element 110 is in contact with the lower surface of the liquid storage medium 103a, the lower surface of the liquid guiding element 110 is in contact with the bottom of the liquid storage cavity 103, and the outer surface of the liquid guiding element 110 is in contact with the wall defining the liquid storage cavity 103. In this way, the second liquid substrate in the liquid storage cavity 202 can be absorbed by the liquid guiding element 110 and transferred to the liquid storage medium 103a when flowing to the liquid storage cavity 103 through the liquid passage, and then indirectly transferred to the liquid guiding element 104a in the atomizing core 104, i.e., absorbed by the liquid guiding element 104a in the atomizing core 104. By such arrangement, the second liquid substrate stored in the liquid storage cavity 202 can flow to the atomizing core 104 more smoothly, avoiding the generation of abnormal sound when the user smokes due to the fast supply of liquid substrate and the problem that the user is easy to smoke the liquid substrate.

[0085] In the above implementation, the material of the liquid guiding element 110 can be the same as or different from that of the liquid storage medium 103a. The density of the liquid guiding element 110 is greater than that of the liquid storage medium 103a. In this way, on the one hand, it can ensure that the liquid guiding element 110 can strongly absorb the liquid substrate in the liquid passage, so that the liquid substrate in the liquid guiding element 110 can be smoothly transferred to the liquid storage medium 103a, and on the other hand, the liquid guiding element 110 can slow down the excessive saturation of the liquid storage medium 103a, reducing the risk of leakage of the liquid substrate.

[0086] In the above implementation, there can be a gap between the wall defining the liquid storage cavity 103 and the outer surface of the liquid storage medium 103a, so that air can communicate with the air portion of the liquid storage cavity 103 through the gap between the wall defining the liquid storage cavity 103 and the outer surface of the liquid storage medium 103a, realizing air exchange.

[0087] In the above implementation, the liquid guiding element 110 is sleeved on the connecting pipe 105a, i.e., the liquid guiding element 110 is arranged around the connecting pipe 105a. The liquid guiding element 110 is located between the liquid passage and the atomizing core 104. The inner diameter of the liquid guiding element 110 is greater than the outer diameter of the connecting pipe 105a, so that a spacing space is formed between the inner surface of the liquid guiding element 110 and the outer surface of the connecting pipe 105a. In this way, the liquid guiding element 110 does not directly contact the atomizing core 104, and at the same time, the liquid storage medium 103a only contacts a part of the atomizing core 104, avoiding the atomizing core 104 from being too saturated with the liquid, and reducing the risk of leakage of the liquid substrate from the liquid storage cavity 103 to the outside.

[0088] In the above implementation, since the protruding portion 104a1 of the liquid guide element 104a extends into the notch groove 105a2 of the connecting pipe 105a, and is exposed in the spacing space between the inner side surface of the liquid guide element 104a and the outer side surface of the connecting pipe 105a, the liquid matrix in the spacing space can be absorbed by the liquid guide element 104a, thereby reducing the risk of leakage of the liquid matrix from the liquid storage cavity 103 to the outside.

[0089] It should be noted that the device body 100 and the liquid storage component 200 are independent of each other. Before the device body 100 and the liquid storage component 200 are connected (i.e., before the first shell 101 and the second shell 201 are connected), the device body 100 can be used and smoked alone, and the atomizing core 104 only atomizes the first liquid matrix. After the device body 100 and the liquid storage component 200 are connected (i.e., after the first shell 101 and the second shell 201 are connected), the atomizing core 104 can atomize both the first liquid matrix and the second liquid matrix. In other examples, the atomizer or the cartridge can be used in combination with the power assembly (or the cigarette rod) first, and then used in combination with the liquid storage component 200.

[0090] It should be noted that the above-mentioned joint is provided on the second shell 201, and the insertion port is provided on the first shell 101, which is also feasible.

[0091] It should be noted that in other examples, before the second shell 201 and the first shell 101 are connected, the electronic atomization device cannot be used and smoked, which is also feasible. That is, only after the second shell 201 and the first shell 101 are connected, the electronic atomization device can be used and smoked, at which time the atomizing core 104 can atomize both the first liquid matrix and the second liquid matrix.
