Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. 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 core for atomizing the liquid matrix. The power supply assembly includes a battery and a circuit board.

[0003] Due to various factors, such as cost and regulations, the amount of liquid matrix stored in a nebulizer is generally small. When the liquid matrix is ​​consumed, the nebulizer can be refilled, replaced, or simply discarded. These methods not only bring inconvenience to users and reduce their user experience, but also increase user costs.

[0004] An existing electronic atomization device uses a large-capacity liquid storage component to replenish the liquid matrix, thereby reducing user costs and improving the user experience. However, a problem with this device is that when the liquid storage component and the electronic atomization device are disassembled, the liquid matrix in the liquid storage component easily leaks out, resulting in liquid matrix waste. This also requires additional components to seal the liquid matrix in the liquid storage component, resulting in a poor user experience. Utility Model Content

[0005] The present application aims to provide an electronic atomization device to avoid the problem of leakage of liquid matrix when the liquid storage component and the electronic atomization device are disassembled.

[0006] The present application provides an electronic atomization device, comprising:

[0007] a first housing component, the first housing component being provided with a first liquid storage cavity for storing a liquid matrix and a first channel communicating with the first liquid storage cavity;

[0008] an atomizing core, disposed in the first housing assembly, and configured to atomize a liquid matrix to generate an aerosol;

[0009] a second housing assembly, the second housing assembly being provided with a second liquid storage cavity for storing a liquid matrix and a second channel communicating with the second liquid storage cavity, the second housing assembly being configured to be removably connected to the first housing assembly along a longitudinal axis of the electronic atomization device;

[0010] a movable member disposed in the second housing assembly, the movable member being used to open or close the second channel, the movable member being capable of rotating about the longitudinal axis of the electronic atomization device between a first position and a second position;

[0011] a conversion mechanism, at least partially disposed on the first housing assembly and / or the second housing assembly, wherein linear movement of the first housing assembly or the second housing assembly along the longitudinal axis can drive the movable member to rotate via the conversion mechanism;

[0012] When the first housing assembly is connected to the second housing assembly, the conversion mechanism drives the movable member to rotate to the first position, thereby opening the second channel and establishing a path for air or liquid matrix to flow between the first liquid storage chamber and the second liquid storage chamber through the first channel and the second channel;

[0013] When the first housing assembly is removed from the second housing assembly, the conversion mechanism drives the movable member to rotate to the second position, thereby closing the second passage.

[0014] In one example, the first housing assembly is provided with a tubular member extending along the longitudinal axis direction, and the second housing assembly is sleeved on the tubular member and can guide the longitudinal displacement of the second housing assembly.

[0015] In one example, a distal end of the tubular member is exposed outside the second housing assembly to form a mouthpiece for a user to inhale.

[0016] In one example, the second liquid storage chamber is disposed around at least a portion of the tubular member.

[0017] In one example, the outer contour of the cross section of the tubular member is non-circular.

[0018] In one example, the first liquid storage chamber and the second liquid storage chamber are arranged sequentially along the longitudinal axis of the electronic atomization device.

[0019] In one example, the second housing component has a through hole, the tubular member can be inserted into the through hole, and a distal end of the tubular member extends out of the second housing component through the through hole.

[0020] In one example, a through hole is provided on the movable member;

[0021] When the movable member rotates to the first position, the through hole is aligned and communicated with the second channel, thereby opening the second channel;

[0022] When the movable member rotates to the second position, the through hole and the second channel are misaligned, thereby closing the second channel.

[0023] In one example, the conversion mechanism includes a sliding groove extending in a spiral or inclined manner.

[0024] In one example, one of the first housing component and the movable part is provided with the slide groove, and the other is provided with a slider; the slider slides in the slide groove, thereby driving the movable part to rotate between the first position and the second position.

[0025] In one example, the first housing component is provided with a support arm extending along the longitudinal axis, and the support arm is provided with the slider or the slide groove; the second housing component is provided with an avoidance groove;

[0026] When the first housing component is connected to the second housing component, the support arm extends into the second housing component through the avoidance groove, so that the sliding block is embedded in the sliding groove.

[0027] In one example, the first channel extends along the longitudinal axis, and an extension length of the first channel is shorter than an extension length of the support arm.

[0028] In one example, the rotation angle of the movable member is between 5° and 30°.

[0029] In one example, the first channel extends along the longitudinal axis;

[0030] The first passage is at least partially located within the second passage when the first housing assembly is connected to the second housing assembly.

[0031] The above-mentioned electronic atomization device can be connected or disassembled through linear movement in the longitudinal direction between the first shell component and the second shell component. At the same time, the conversion mechanism can drive the movable part to rotate around the longitudinal axis, thereby opening or closing the channel; this can avoid the problem of leakage of liquid matrix during disassembly and improve the user experience.

[0043] 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.

The terms "upper", "lower", "left", "right", "inside", "outside" and similar expressions used in this specification are for illustrative purposes only.

[0044] 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.

[0045] 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.

[0046] like Figures 1-5 As shown, the electronic atomization device 100 provided in the embodiment of the present application includes a first shell assembly 101. The first shell assembly 101 can be composed of multiple parts, for example, a main shell 101a and a top cover 101b arranged on the top of the main shell 101a. The first shell assembly 101 can also be formed as one piece.

[0047] The first housing assembly 101 is provided with a tubular member 102 . The tubular member 102 protrudes from the top wall of the first housing assembly 101 , that is, extends along the longitudinal axis of the electronic atomization device 100 .

[0048] The first housing assembly 101 is formed with a liquid storage chamber 103 (first liquid storage chamber) that is used to store the first liquid matrix. The first liquid matrix can be the liquid that comprises the tobacco-containing material that contains volatile tobacco flavor components, or can be the liquid that comprises non-tobacco substances. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture. Spices can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this. Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user. Vitamin mixture can be the material that is mixed with at least a among vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this. In addition, the first liquid matrix can comprise the aerosol forming agent as glycerol and propylene glycol.

[0049] A liquid storage medium 103 a is provided in the liquid storage chamber 103 , and a sealing member 103 b is provided at the lower end of the liquid storage chamber 103 , so that the lower end of the liquid storage chamber 103 is sealed by the sealing member 103 b .

[0050] The liquid storage medium 103a is made of, for example, a fiber material or a porous material. Figure 6 As shown, 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 atomizer core 104. After injection, when the liquid storage medium 103a reaches saturation, the liquid matrix content in the liquid storage medium 103a ranges from 0.1ml to 2ml, for example, 0.5ml, 0.8ml, 1ml, 1.5ml, or 2ml. The space between the end surface of the liquid storage medium 103a and the first housing assembly 101 defines an air portion.

[0051] An atomizing core 104 is disposed in the first housing assembly 101 , and the atomizing core 104 is used to atomize a liquid matrix to generate an aerosol.

[0052] like Figures 7-8As shown, the atomizer core 104 includes a liquid guide element 104a and a heating element 104b. The liquid guide 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 electric current and transfer heat to the liquid matrix in contact with the heating element 104b to heat the liquid matrix, thereby generating an aerosol.

[0053] 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.

[0054] 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.

[0055] The first housing assembly 101 includes an airflow channel 105 for transmitting the aerosol generated by the atomizing core 104 to the tubular member 102 for inhalation by the user. The lower end of the airflow channel 105 is connected to the air inlet 101c, which can be provided on the bottom wall of the first housing assembly 101; the upper end of the airflow channel 105 is connected to the tubular member 102, and the user can inhale the aerosol through the air outlet or the mouthpiece of the tubular member 102 (the dotted arrow in the figure indicates the direction of airflow in the airflow channel 105).

[0056] like Figures 7-8As shown, a connecting tube 105a is disposed within the first housing assembly 101. The hollow portion within the connecting tube 105a defines a portion of the airflow channel 105. The connecting tube 105a extends along the longitudinal axis of the liquid storage chamber 103. The upper end of the connecting tube 105a is connected to the tubular member 102, and the lower end of the connecting tube 105a is connected to the sealing member 103b. The connecting tube 105a is preferably made of a relatively thin rigid material, such as fiberglass or stainless steel.

[0057] 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 core 104 is disposed within the connecting tube 105a. The atomizer core 104 and the connecting tube 105a are arranged coaxially. The side wall of the connecting tube 105a also has a liquid guide port 105a1, and the liquid storage medium 103a covers the liquid guide port 105a1. 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 core 104 through the liquid guide port 105a1, that is, to be sucked by the liquid guide element 104a and atomized by the heating element 104b to generate an inhalable aerosol.

[0058] The sidewall of the connecting tube 105a is also provided with a notch 105a2, extending from the upper end of the connecting tube 105a toward the lower end. 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 the protruding portion 104a1, thereby facilitating the liquid-conducting element 104a to absorb the liquid medium.

[0059] A circuit 106 is also provided within the first housing assembly 101 and is disposed near the bottom wall of the first housing assembly 101. The circuit 106 can control 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 core 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.

[0060] 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.

[0061] The battery cell 107 is disposed between the seal 103b and the circuit 106. 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 also provide power required to operate the circuit 106. In addition, the battery cell 107 can also provide power required to operate other components provided in the electronic atomization device 100.

[0062] 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. In a preferred embodiment, a charging port is also provided within the first housing assembly 101 to charge the rechargeable battery.

[0063] It should be noted that the figure only shows the components related to this embodiment. A person skilled in the art should understand that the electronic atomization device 100 may also include Figures 1-8 Other common components other than the components shown. For example, a puff detector 108 may also be provided in the first shell assembly 101, which is used to detect the user's puffing action and generate a corresponding electrical signal, that is, to detect whether the electronic atomization device 100 is puffed, so that the circuit 106, such as the control unit, controls the operation of the battery cell 107, the heating element, etc. according to the electrical signal, such as 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 108 can adopt common pressure sensors, differential pressure sensors, airflow sensors, etc. The puff detector 108 is connected to the airflow channel 105, so that when the user puffs, it can sense the changes in the puff airflow.

[0064] It also needs to be explained that Figures 1-8 In the example, the above components are formed integrally, 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 108 are located in the power supply assembly. It is also feasible that the tubular member 102, liquid storage chamber 103, and atomizing core 104 are located in the atomizer.

[0065] Please combine Figures 9-10 It is understood that the liquid storage component 200 provided in the embodiment of the present application includes a second housing assembly 201, and the second housing assembly 201 can be composed of multiple components, such as a main body 201a and a bottom cover 201b.

[0066] The second housing assembly 201 is removably connected to the first housing assembly 101. The second housing assembly 201 is removably connected to the first housing assembly 101 along the longitudinal axis of the electronic atomization device 100. The connection method between the second housing assembly 201 and the first housing assembly 101 is not limited and can be an interference fit, a snap connection, a magnetic connection, etc.

[0067] When the second housing assembly 201 is connected to the first housing assembly 101, the second housing assembly 201 is sleeved over the tubular member 102 and guides the longitudinal displacement of the first housing assembly 101. The distal end of the tubular member 102 is exposed outside the second housing assembly 201 to form a mouthpiece for the user to draw from. Specifically, the second housing assembly 201 has a through hole 201c extending through the upper and lower surfaces. The tubular member 102 can be inserted into the through hole 201c, and the distal end of the tubular member 102 extends through the through hole 201c to the outside of the second housing assembly 201. In a preferred embodiment, the outer contour of the cross section of the tubular member 102 is non-circular, for example, it can be elliptical, square, etc.; in this way, on the one hand, when the second shell component 201 is connected to the first shell component 101, it can only be docked along a specific orientation, which is beneficial to the alignment and connection of the second channel with the first channel; on the other hand, when the second shell component 201 is connected to the first shell component 101, the rotation of the second shell component 201 can be limited, which facilitates the conversion mechanism to drive the movable part 204 to rotate along the circumferential direction of the electronic atomization device 100, that is, to rotate around the longitudinal axis of the electronic atomization device 100.

[0068] The second housing assembly 201 is formed with a liquid storage chamber 202 (second liquid storage chamber) that is used to store the second liquid matrix. Similar to the first liquid matrix, the second liquid matrix can be the liquid that comprises the tobacco-containing material that contains volatile tobacco flavor components, can also be the liquid that comprises non-tobacco substances. For example, the liquid matrix can comprise water, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture. Spices can comprise menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this. Flavoring agent can comprise the composition that can provide multiple fragrance or local flavor to the user. Vitamin mixture can be the material that is mixed with at least a among vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this. In addition, the second liquid matrix can comprise the aerosol forming agent as glycerol and propylene glycol.

[0069] 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.

[0070] 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 is not provided in liquid storage chamber 202.

[0071] The liquid storage chamber 202 is disposed around at least a portion of the tubular member 102. When the second housing assembly 201 is connected to the first housing assembly 101, the liquid storage chamber 202 and the liquid storage chamber 103 are sequentially arranged along the longitudinal axis of the electronic atomization device 100.

[0072] When the second housing assembly 201 is connected to the first 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.

[0073] Specifically, a first channel is also provided on the first shell component 101, and the first channel includes a channel 109 and a channel 110 that are spaced apart and located on both sides of the tubular member 102. Both the channel 109 and the channel 110 protrude from the top wall of the first shell component 101, that is, extend along the longitudinal axis of the electronic atomization device 100. Specifically, one end of the channel 109 is communicated with the liquid storage chamber 103, and the other end of the channel 109 protrudes from the top wall of the first shell component 101 and is communicated with the outside of the first shell component 101; one end of the channel 110 is communicated with the liquid storage chamber 103, and the other end of the channel 110 protrudes from the top wall of the first shell component 101 and is communicated with the outside of the first shell component 101. Liquid matrix can be replenished to the liquid storage chamber 103 through the channel 109, and air can be replenished or discharged to the liquid storage chamber 103 through the channel 110. In one example, when the second housing assembly 201 is not connected to the first housing assembly 101 , the channel 109 or the channel 110 may be sealed by a seal, such as a removable silicone plug or silicone cap, or a puncturable film.

[0074] Second housing assembly 201 also includes a second channel, comprising a channel 201b1 and a channel 201b2, spaced apart from each other. One end of channel 201b1 communicates with liquid storage chamber 202, while the other end is located on the bottom wall of second housing assembly 201 and communicates with the exterior of second housing assembly 201. One end of channel 201b2 communicates with liquid storage chamber 202, while the other end is located on the bottom wall of second housing assembly 201 and communicates with the exterior of second housing assembly 201. Liquid in liquid storage chamber 202 can flow out through channel 201b1, while air can be added to or removed from liquid storage chamber 202 through channel 201b2.

[0075] When the second housing assembly 201 is connected to the first housing assembly 101, the second channel can dock with the first channel, that is, channel 201b1 docks with channel 109, and channel 201b2 docks with channel 110. In a specific embodiment, at least a portion of channel 109 is located in channel 201b1, and at least a portion of channel 110 is located in channel 201b2. In a further embodiment, a seal 203 is further provided in the second housing assembly 201. The seal 203 can be made of silicone. The seal 203 is provided on the bottom cover 201b, and a portion of the seal 203 is located in channels 201b1 and 201b2. When the second channel docks with the first channel, the seal 203 can seal the gap between channel 201b1 and channel 109, and the gap between channel 201b2 and channel 110.

[0076] Channel 201b1 and channel 109 together define a liquid channel, thereby providing a path for the first liquid matrix and / or the second liquid matrix to flow between liquid storage chamber 103 and liquid storage chamber 202. One end of the liquid channel is connected to liquid storage chamber 103, while the other end of the liquid channel is connected to liquid storage chamber 202.

[0077] Channel 201b2 and channel 110 together define an air channel, which provides a path for air flow between liquid storage chamber 103 and liquid storage chamber 202. One end of the air channel communicates with the air portion of liquid storage chamber 103, while the other end communicates with the air portion of liquid storage chamber 202. The air channel balances the air pressure difference between liquid storage chamber 103 and liquid storage chamber 202, allowing the second liquid matrix stored in liquid storage chamber 202 to flow smoothly through the liquid channel to liquid storage chamber 103, thus promptly replenishing consumed liquid matrix in liquid storage chamber 103 and preventing the negative pressure generated by the reduction of liquid matrix in liquid storage chamber 103 from preventing the remaining liquid matrix from flowing further into liquid storage chamber 202.

[0078] The second housing assembly 201 is also provided with a movable member 204. This member is disposed within the second housing assembly 201 and sandwiched between the bottom cover 201b and a bracket 205 within the second housing assembly 201. A seal 206 can be provided between the bracket 205 and the inner wall of the second housing assembly 201, and a seal 207 can be provided between the bracket 205 and the movable member 204, thereby achieving a good seal. Both seals 206 and 207 can be made of silicone.

[0079] The movable member 204 is configured to be able to rotate around the longitudinal axis of the electronic atomization device 100 in a first position (refer to Figure 4 shown) and the second position (reference Figure 5 as shown) to open or close the second channel.

[0080] When the second housing assembly 201 is connected to the first housing assembly 101, the movable member 204 rotates to the first position, thereby opening the second channel and establishing a path for air or liquid substrate to flow between the liquid storage chamber 103 and the liquid storage chamber 202 through the first and second channels. Specifically, when the second channel is opened, one end of channel 201b1 communicates with the liquid storage chamber 202, and a path for liquid substrate to flow between the liquid storage chamber 103 and the liquid storage chamber 202 is established through channel 201b1 and channel 109. When the second channel is opened, one end of channel 201b2 communicates with the liquid storage chamber 202, and a path for air to flow between the liquid storage chamber 103 and the liquid storage chamber 202 is established through channel 201b2 and channel 110.

[0081] When the second housing assembly 201 is removed from the first housing assembly 101, the movable member 204 rotates to the second position, thereby closing the second channel. Specifically, when the second channel is closed, one end of the channel 201b1 is disconnected from the liquid storage chamber 202, preventing the liquid matrix from flowing between the liquid storage chamber 103 and the liquid storage chamber 202 via the channel 201b1 and the channel 109. When the second channel is closed, one end of the channel 201b2 is disconnected from the liquid storage chamber 202, preventing air from flowing between the liquid storage chamber 103 and the liquid storage chamber 202 via the channel 201b2 and the channel 110.

[0082] In one specific example, the movable member 204 is configured to rotate about the longitudinal axis of the electronic atomization device 100 between a first position and a second position, thereby opening or closing the second channel. Specifically, when the second housing assembly 201 is connected to the first housing assembly 101, the movable member 204 rotates to the first position, thereby opening the second channel; when the second housing assembly 201 is removed from the first housing assembly 101, the movable member 204 rotates to the second position, thereby closing the second channel. The rotation angle of the movable member 204 is between 5° and 30°, or between 5° and 25°, or between 5° and 20°, or between 5° and 15°.

[0083] The movable member 204 may be provided with a through hole 204a corresponding to the channel 201b1, and a through hole 204b corresponding to the channel 201b2. When the movable member 204 rotates to the first position, the through hole 204a aligns and connects with the channel 201b1, and the through hole 204b aligns and connects with the channel 201b2, thereby opening the channels 201b1 and 201b2, i.e., opening the second channel. When the movable member 204 rotates to the second position, the through hole 204a is misaligned with the channel 201b1, and the through hole 204b is misaligned with the channel 201b2, thereby closing the channels 201b1 and 201b2, i.e., closing the second channel.

[0084] The rotation of the movable member 204 can be driven by a conversion mechanism disposed on the first housing assembly 101. Linear movement of the first housing assembly 101 or the second housing assembly 201 along the longitudinal axis can, via the conversion mechanism, drive the movable member 204 to rotate. Specifically, when the second housing assembly 201 is connected to the first housing assembly 101, the conversion mechanism can drive the movable member 204 to rotate to the first position, thereby opening the second passage. When the second housing assembly 201 is removed from the first housing assembly 101, the conversion mechanism can drive the movable member 204 to rotate to the second position, thereby closing the second passage.

[0085] Please combine Figure 2 、 Figure 9To understand, a support arm 111 is also protruding from the top wall of the first housing assembly 101, that is, the support arm 111 extends along the longitudinal axis of the electronic atomization device 100. A slider 111a is provided on the support arm 111; a slide groove 204c is provided on the side wall of the movable member 204, and the slide groove 204c extends in a spiral or inclined manner, and the slide groove 204c defines the aforementioned conversion mechanism. The extension length of the support arm 111 is greater than the extension length of the channel 109 or the channel 110. In this way, the support arm 111 can extend into the second housing assembly 201 before the channel 109 or the channel 110, through the avoidance groove 201b3 on the side wall of the bottom cover 201b, so that the slider 111a is embedded in the slide groove 204c. Similar to the above, through the structural design of the support arm 111 and the avoidance groove 201b3, on the one hand, when the second shell component 201 is connected to the first shell component 101, the docking of the second channel and the first channel is facilitated; on the other hand, when the second shell component 201 is connected to the first shell component 101, it can only be docked along a specific orientation, which is conducive to the alignment and connection of the second channel and the first channel; on the other hand, when the second shell component 201 is connected to the first shell component 101, the rotation of the second shell component 201 can be limited, which facilitates the conversion mechanism to drive the movable part 204 to rotate along the circumferential direction of the electronic atomization device 100, that is, to rotate around the longitudinal axis of the electronic atomization device 100.

[0086] When the second shell component 201 is connected to the first shell component 101, for example, when the second shell component 201 is connected to the first shell component 101 along the longitudinal axis direction of the electronic atomization device 100 (for example, the upward direction), the slider 111a slides in the slide groove 204c, thereby driving the movable part 204 to rotate along the circumferential direction of the electronic atomization device 100 or the second shell component 201 (for example, the clockwise direction) to the first position, thereby opening the second channel.

[0087] When the second shell component 201 is removed from the first shell component 101, for example, when the second shell component 201 is connected to the first shell component 101 along the longitudinal axis direction of the electronic atomization device 100 (for example, the downward direction), the slider 111a slides in the slide groove 204c (opposite to the aforementioned sliding direction), thereby driving the movable part 204 to rotate along the circumferential direction of the electronic atomization device 100 or the second shell component 201 (for example, the counterclockwise direction) to the second position, thereby closing the second channel.

[0088] It is understandable that it is also feasible to arrange the slider and the slide groove in reverse, that is, the slider is arranged on the movable member 204 , and the slide groove is arranged on the first housing assembly 101 .

[0089] It can be understood that the above-mentioned conversion mechanism mainly converts the linear movement of the first shell component 101 or the second shell component 201 along the longitudinal axis into rotation around the longitudinal axis of the electronic atomization device 100. In other examples, the above-mentioned movement changes can also be achieved through a screw mechanism, a gear rack mechanism, etc., which will not be elaborated here.

[0090] It should also be understood that in the above example, the movable member is disposed on the second housing assembly 201. In other examples, it is also feasible to dispose the movable member on the first housing assembly 101, and to open or close the first channel by moving the movable member between a first position and a second position. In this example, the movement of the movable member can be driven by a conversion mechanism. In another example, the movable member can also simultaneously open and close the first and second channels.

[0091] It should be noted that the above-mentioned electronic atomization device 100 and liquid storage component 200 are independent of each other. Before the electronic atomization device 100 and the liquid storage component 200 are not connected (that is, before the first shell component 101 and the second shell component 201 are not connected), the electronic atomization device 100 can be used alone and inhaled, and the atomization core 104 only atomizes the first liquid matrix. After the electronic atomization device 100 and the liquid storage component 200 are connected (that is, after the first shell component 101 and the second shell component 201 are connected), the atomization core 104 can atomize both the first liquid matrix and the second liquid matrix. The combination of the electronic atomization device 100 and the liquid storage component 200 can also be collectively referred to as an electronic atomization device. 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.

[0092] 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.
