Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an electronic atomization device. Background Technology

[0002] In electronic atomizing devices, the atomizing core heats and atomizes the atomizing matrix stored in the reservoir to produce an aerosol, which is then output through the atomizing air passage. During use, the user inhales through the atomizing air passage, causing airflow changes within the passage. The airflow switch senses these changes and generates a trigger signal to activate the atomizing core.

[0003] During the aerosol output process through the atomizing air channel, the aerosol condenses and adheres to the air channel wall due to temperature changes, forming condensate. This condensate is prone to backflow, causing corrosion to the airflow switch and affecting the normal use of the product. Utility Model Content

[0012] In some embodiments, the heating element is sheet-shaped, and the fixing component has an atomizing window extending through its thickness direction. The heating element is attached to and fixed to the surface of the fixing component on one side of the thickness direction and exposed to the atomizing window.

[0013] In some embodiments, the atomizing assembly further includes a seal, and the fixing assembly is provided with a sealing groove on the side facing the mounting assembly. The sealing groove surrounds the air guide channel, and the seal is disposed in the sealing groove to seal the gap between the fixing assembly and the mounting assembly.

[0014] In some embodiments, the liquid storage tank is provided with a plurality of liquid storage chambers, which are arranged around the atomizing gas channel; each liquid storage chamber is provided with a liquid outlet communicating with the atomizing gas channel, and each liquid storage chamber is equipped with a liquid storage component that blocks the corresponding liquid outlet.

Detailed Implementation

[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0037] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0038] The part numbers assigned in this document may be rearranged or adjusted in an obvious manner. Therefore, the specification and drawings are only for the clear description of one embodiment and do not imply that they are necessarily connected (joined) by other elements, materials, including both direct and indirect connections.

[0039] Electronic atomizing devices can heat and atomize an atomizing matrix to produce an aerosol. The atomizing matrix can be an atomizing liquid, which may be a liquid containing glycerin or propylene glycol, or a drug solution. The atomizing matrix can also be plant leaves, tobacco paste, etc. The atomizing device can atomize plant leaves, tobacco paste, atomizing liquid, etc., to produce an aerosol for the user to inhale. The atomizing matrix can also be water, which the atomizing device can atomize to humidify the air. The atomizing matrix can also be a liquid or paste-like aromatherapy product, which the atomizing device can atomize to purify or improve air quality. This application does not limit the objects atomized by the electronic atomizing device; the specific selection can be based on actual needs. In the following embodiments, the atomization of plant leaves, tobacco paste, e-liquid, etc., to produce an aerosol is used as an example. Specifically, e-liquid is used as an example; for ease of description, e-liquid is referred to as the atomizing matrix.

[0040] In related technologies, electronic atomizing devices are equipped with an air intake channel coaxially connected to the atomizing channel. The airflow switch is typically coaxially connected to the air intake channel. During inhalation, external air enters the atomizing channel through the air intake channel. The airflow switch senses this change in airflow and activates the atomizing component to heat and atomize the atomizing matrix, generating an aerosol. This aerosol is then output from the atomizing channel. In practical applications, condensation during aerosol transport can easily flow back into the air intake channel, corroding the airflow switch and potentially causing it to automatically restart, resulting in burnt coils.

[0041] To address the aforementioned issues, this application provides an electronic atomizing device that uses an independently designed detection airway to prevent condensate backflow from causing corrosion and damage to the airflow switch.

[0042] See Figures 1-8 As shown, the electronic atomizing device 100 provided in this application includes a liquid storage device 10 and an atomizing device 20. The liquid storage device 10 stores an atomizing matrix, and the atomizing device 20 can heat and atomize the atomizing matrix stored in the liquid storage device 10 to produce an aerosol. The atomizing matrix specifically refers to e-liquid that can be heated and atomized to produce an aerosol that can be inhaled by the user.

[0043] The liquid storage device 10 includes a liquid storage chamber 11 and a liquid storage component 12. The liquid storage chamber 11 is provided with a liquid storage cavity 111 and an atomizing air channel 131. The liquid storage cavity 111 and the atomizing air channel 131 are relatively independent. The liquid storage cavity 111 is provided with a liquid outlet 112 that communicates with the atomizing air channel 131. The liquid storage component 12 is disposed in the liquid storage cavity 111. A portion of the liquid storage component 12 is blocked from the liquid outlet 112. The liquid storage component 12 is used to store the atomizing matrix. The portion of the liquid storage component 12 blocked from the liquid outlet 112 is exposed to the atomizing air channel 131 through the liquid outlet 112.

[0044] The atomizing device 20 includes a mounting assembly 21, an airflow switch 22, and an atomizing assembly 23. The mounting assembly 21 is used to mount the airflow switch 22 and the atomizing assembly 23. The mounting assembly 21 also has an air inlet channel 2122 and a detection channel 2123. The mounting assembly 21 is connected to the liquid storage tank 11. The atomizing assembly 23 includes a fixing component 231 and a heating element 232. The heating element 232 is installed in the thickness direction of the fixing component 231. Figure 4 On one side (shown in the X-axis direction), the fixing component 231 is located on the side of the mounting component 21 facing the liquid storage tank 11. The heating element 232 can contact the portion of the liquid storage component 12 located at the liquid outlet 112 from the outlet 112. The liquid storage component 12 can then conduct the stored atomizing matrix to the heating element 232, which can then heat and atomize the atomizing matrix to generate an aerosol. The generated aerosol is output through the atomizing air passage 131. An airflow switch 22 is located on the side of the mounting component 21 facing away from the liquid storage tank 11. The airflow switch 22 is electrically connected to the heating element 232. This airflow switch 22 can generate a change in capacitance based on changes in airflow or air pressure to generate a start signal to control the heating of the heating element 232.

[0045] The liquid storage assembly 12 can be a structure consisting only of a liquid storage element, while the atomizing assembly 23 can be a structure including a heating element 232 covered by a liquid guiding element. When the heating element 232 contacts the liquid storage assembly 12, the atomizing matrix stored in the liquid storage element can be conducted to the heating element through the liquid guiding element. Alternatively, the liquid storage assembly 12 can consist of a liquid storage element and a liquid guiding element, while the atomizing assembly 23 can be a structure consisting only of the heating element 232. When the heating element 232 contacts the liquid storage assembly 12, the atomizing matrix stored in the liquid storage element can be conducted to the heating element 232 through the liquid guiding element in the liquid storage assembly 12. For the specific structures of the liquid storage assembly 12 and the atomizing assembly 23, please refer to the following embodiments.

[0046] In this embodiment, both the air inlet duct 2122 and the detection duct 2123 penetrate the mounting assembly 21 on the side facing the liquid storage tank 11. The two ends of the detection duct 2123 are fluidly connected to the atomizing duct 131 and the airflow switch 22, respectively. For example, the two ends of the detection duct 2123 are fluidly connected to the atomizing duct 131 and the airflow switch 22 through pipes or other structures. The fixing assembly 231 is positioned along its height direction (e.g., ...). Figure 4 and Figure 8 An air guide channel 2310 is provided through the Z-axis direction (as shown). An air inlet channel 2122 is fluidly connected to the atomizing channel 131 through the air guide channel 2310. The air inlet channel 2122 is connected to the outside of the electronic atomizing device 100. When the air pressure in the atomizing channel 131 is lower than the external air pressure, external air enters the atomizing channel 131 sequentially through the air inlet channel 2122 and the air guide channel 2310 to form an airflow. This airflow causes a change in airflow or air pressure in the detection channel 2123. The change in airflow or air pressure is sensed by the airflow switch 22 to generate a start signal to control the heating element 232 to start. The started heating element 232 can heat and atomize the atomizing matrix to generate aerosol. The generated aerosol enters the atomizing channel 131 with the airflow in the air guide channel 2310 and flows with the airflow in the atomizing channel 131 to be output and provided to the user.

[0047] In this embodiment, external air enters the atomizing airway 131 sequentially through the air intake duct 2122 and the air guide duct 2310. The air guide duct 2310 is designed so that the atomizing window 233 is closer to the airflow path that enters through the air guide duct 22122, which is conducive to the output of aerosol with the airflow.

[0048] The aerosol generated by the heating element 232 heating the atomized matrix stored in the liquid storage component 12 is sprayed into the airflow path of the airflow guide channel 2310, or directly sprayed into the airflow guide channel 2310, so that the airflow formed by the external air in the airflow guide channel 2310 is closer to the aerosol, so as to ensure that the aerosol flows with the airflow.

[0049] It should be noted that the atomizing air duct 131 penetrates the liquid storage chamber 11 in the vertical direction (e.g., Figure 4 (As shown in the Z-axis direction), one end of the atomizing airway 131 is connected to the outside of the electronic atomizing device 100, while the other end of the atomizing airway 131 is connected to the air guide airway 2310 and the detection airway 2123 after the liquid storage chamber 11 is connected to the mounting assembly 21. In actual use, the user can draw in air at one end of the atomizing airway 131, causing a change in air pressure within the atomizing airway 131, so that outside air can enter the atomizing airway 131 through the air intake airway 2122.

[0050] To facilitate user use, the liquid storage device 10 also includes a suction nozzle 14. The suction nozzle 14 is provided with a suction nozzle channel 141. The suction nozzle 14 is sealed and installed at one end of the liquid storage chamber 11 along the axial direction of the atomizing air channel 131, and keeps the suction nozzle channel 141 in communication with the atomizing air channel 131. The user can perform suction through the suction nozzle 14.

[0051] In this application, the atomizing airway 131, the inlet airway 2122, and the detection airway 2123 are relatively independent airways, maintaining only a fluid conduction state. The detection airway 2123 only has the function of sensing airflow or pressure changes by the airflow switch 22. It can be staggered or crossed relative to the atomizing airway 131 and the inlet airway 2122. Condensate generated by temperature changes in the aerosol flowing through the atomizing airway 131 is less likely to flow back into the detection airway 2123, thus avoiding corrosion damage to the airflow switch 22. Simultaneously, the air guide channel 2310 on the fixing component 231 brings the airflow closer to the airflow, ensuring that the aerosol can flow and be output synchronously with the airflow.

[0052] See Figures 2-4 As shown, the liquid storage chamber 11 is also provided with a transition chamber 15. The detection air passage 2123 and the atomizing air passage 131 are offset from each other in the extension direction perpendicular to the air inlet air passage 2122, so that the detection air passage 2123 and the atomizing air passage 131 are in a non-coaxial state. The transition chamber 15 conducts fluid between the detection air passage 2123 and the atomizing air passage 131, which can prevent the condensate from flowing back into the detection air passage 2123.

[0053] In some embodiments, the intake duct 2122 and the detection duct 2123 are non-coaxial with the atomizing duct 131 to further avoid the phenomenon of condensate backflow.

[0054] In this embodiment, the transition cavity 15 is recessed on the side of the liquid storage tank 11 facing the mounting assembly 21. In a specific embodiment, such as... Figure 6 As shown, a transition groove 151 is recessed on the side of the liquid storage tank 11 facing the mounting component 21. After the liquid storage tank 11 is connected to the mounting component 21, the transition groove 151 and the side of the mounting component 21 facing the liquid storage tank 11 form a transition cavity 15. The transition cavity 151 causes the path of the liquid flowing through the detection gas channel 2123 to bend, so as to prevent the condensate from flowing back into the detection gas channel 2123.

[0055] Of course, in some embodiments, there is a possibility that the condensate may flow along the transition cavity 15 to the detection airway 2123. To address this, an annular blocking protrusion can be provided around the airway opening at the end of the detection airway 2123 that penetrates the mounting assembly 21 to block the backflow of condensate. Alternatively, a liquid-absorbing element can be provided around the airway opening at the end of the detection airway 2123 that penetrates the mounting assembly 21 to absorb the backflow of condensate and prevent it from flowing into the detection airway 2123. The transition cavity 15 can also be configured in a bent shape, a wavy shape, etc., to further prevent condensate backflow.

[0056] See Figure 4 As shown, the heating element 232 is sheet-shaped, and the fixing assembly 231 is along its thickness direction ( Figure 4 An atomizing window 233 is provided through the fixed assembly 231 along the thickness direction (shown in the X-axis direction). A sheet-like heating element 231 is attached and fixed to the surface of the fixed assembly 231 along its thickness direction and exposed to the atomizing window 233. The atomizing window 233 is equivalent to a structure that is hollowed out along the thickness direction of the fixed assembly 231. It can be considered that after the heating element 231 is attached and fixed to the surface of the fixed assembly 231 along its thickness direction, it can cover the atomizing window 233. The fixed assembly 231 is located on the side of the mounting assembly 21 facing the liquid storage tank 11. After the mounting assembly 21 is connected to the liquid storage tank 11, the sheet-like heating element 232 can contact the liquid storage assembly 12 from the liquid outlet 112 on the side facing away from the fixed assembly 231. The liquid storage assembly 12 can then provide the atomizing matrix to the heating element 232. The heating element 232 heats the atomizing matrix to generate an aerosol by heating. The air guide channel 2310 is along the height direction of the fixed assembly 231 (shown in the X-axis direction). Figure 4 The heating element 232 is installed through the Z-axis direction. The heating element 232 is fluidly connected to the atomizing airway 131 and the air guide airway 2310 through the atomizing window 233. In this way, the aerosol generated by the heating element 232 heating the atomizing substrate is sprayed into the air guide airway 2310 or the atomizing airway 131 through the atomizing window 233. The aerosol can then flow out from one end of the atomizing airway 131 with the airflow flowing through the air guide airway 2310 or the airflow flowing through the atomizing airway 131.

[0057] In some embodiments, the fixing component 231 is further provided with a clearance notch 23123 on one side along its thickness direction, wherein the heating element 232 is connected to the clearance notch 23123 through the atomizing window 233, and the airflow path of the air guide channel 2310 passes through the clearance notch 23123 to ensure that the airflow through the air guide channel 2310 is closer to the atomizing window 233.

[0058] See Figures 2-4 as well as Figure 11 As shown, the atomizing assembly 23 also includes a sealing element 234, such as Figure 11As shown, the fixing component 231 is also provided with a sealing groove 23122 on the side facing the mounting component 21. The sealing groove 23122 surrounds the air guide channel 2310. The sealing element 234 is disposed in the sealing groove 23122. The sealing element 234 is preferably a sealing sleeve or annular structure, used to seal the gap between the fixing component 231 and the mounting component 21 to prevent airflow from leaking from the gap between the fixing component 231 and the mounting component 21.

[0059] See Figures 2-4 , Figures 8-10 As shown, the sheet-like heating element 232 includes a heating part 2321 and a conductive part 2322. The heating part 2321 and the conductive part 2322 are connected. The heating part 2321 and the conductive part 2322 can form an integral structure after being connected. Of course, the two are detachably connected and are independent structures. The connected heating part 2321 and the conductive part 2322 are sheet-like and are attached and fixed to the surface of the fixing assembly 231 on one side in the thickness direction. The heating part 2321 is exposed to the atomization window 233.

[0060] In this embodiment, the heating element 2321 generates heat under the action of electrical energy, thus heating the atomized matrix. The conductive element 2322 directly or indirectly connects the heating element 2321 to the power supply unit 25, providing the heating element 2321 with the electrical energy required for heating. Correspondingly, the heating element 2321 contacts the liquid storage assembly 12 from the liquid outlet 112.

[0061] In some embodiments, the atomizing device 20 further includes an electrical connector 24 disposed on the side of the mounting assembly 21 facing the liquid storage tank 11. The electrical connector 24 is used to make contact with the conductive part 2322 to electrically connect the power supply unit 25 and the heating part 2321 through the conductive part 2322, thereby providing the heating part 2321 with the electrical energy required for heating through the power supply unit 25.

[0062] In this application, the power supply unit 25 can be independent of the electronic atomizing device 100, or it can be part of the atomizing device 20. For example, the power supply unit 25 can be installed inside the mounting assembly 21, so that the atomizing device 20 has both heating and power supply functions. Please refer to the following embodiments for details.

[0063] See Figure 3 , Figure 5 and Figure 6 As shown, the liquid storage chamber 11 is provided with multiple liquid storage cavities 111, which are arranged around the atomizing air channel 131. Each liquid storage cavity 111 is provided with a liquid outlet 112 communicating with the atomizing air channel 131, and each liquid storage cavity 111 is equipped with a liquid storage component 12 that blocks the corresponding liquid outlet 112.

[0064] like Figures 2-4 as well as Figure 8 As shown, the mounting assembly 21 has a slide 2124 on the side facing the liquid storage tank 11. The fixing assembly 231 is slidably disposed in the slide 2124 between the contact position and the detachment position, allowing the heating part 2321 of the heating element 232 to contact or detach from the liquid storage assembly 12 from different liquid outlets 112. Specifically, when the fixing assembly 231 slides along the slide 2124 to the contact position, the heating part 2321 of the heating element 232 can contact the liquid storage assembly 12 from the liquid outlet 112. Furthermore, the electrical connector 24 is disposed in the contact position. When the fixing assembly 231 is in the contact position, the conductive part 2322 can contact and connect to the electrical connector 24. This ensures that while the heating part 2321 contacts the liquid storage assembly 12 from the liquid outlet 112, the heating part 2321 is connected to the power supply unit 25 through the conductive part 2322 and the electrical connector 24, thereby synchronizing atomization with air intake. When the fixing component 231 slides along the slide 2124 to the disengagement position, the heating part 2321 of the heating element 232 can be disengaged from the liquid storage component 12, and the conductive part 2322 can be separated from the electrical connector 24.

[0065] Specifically, when the fixing component 231 is in the contact position, the air guide passage 2310 and the air intake passage 2122 can remain in communication, while when the fixing component 231 is in the disengaged position, the air guide passage 2310 and the air intake passage 2122 are misaligned.

[0066] In this embodiment, the heating element 2321 has multiple air channels or pores that penetrate the thickness direction of the heating element 232. The air channels or pores connect the liquid storage component 12 and the atomization window 233. The aerosol generated after the atomization matrix stored in the liquid storage component 12 is atomized can pass through the air channels or pores on the heating element 2321 and the atomization window 233, and finally enter the atomization air channel 131.

[0067] In one embodiment, the heating element 2321 is a mesh heating wire or a perforated heating plate, with the perforated portion forming air channels or pores. After the heating element 2321 contacts the liquid storage component 12, the aerosol generated by heating and atomizing the atomizing matrix stored in the liquid storage component 12 can be ejected from the atomization window 233 through the perforated structure. The heating element 232 is provided with two conductive parts 2322, which are respectively formed as two conductive pins of the heating element 2321. The two conductive parts 2322 can be located on both sides of the heating element 2321. Correspondingly, two electrical connectors 24 are provided, which are respectively connected to the positive and negative terminals of the power supply unit 25. When the fixing component 231 slides to the contact position, the two conductive parts 2322 respectively contact the two electrical connectors 24.

[0068] In this application, the atomizing matrix stored in the storage components 12 of each storage chamber 111 in the storage tank 11 can be of the same or different types to produce aerosols with different flavors to meet different user needs. When the atomizing matrix stored in one of the storage components 12 is used up, it is necessary to switch different storage components 12 to the contact position. To do this, the mounting component 21 is rotatably connected to the storage tank 11, and the storage tank 11 and the mounting component 21 are rotated relative to each other to switch different storage chambers 111 to the contact position, thereby switching different storage components 12 to the contact position.

[0069] Since the heating element 2321 of the heating element 232 in the contact atomizing assembly 23 contacts the liquid storage assembly 12 from the liquid outlet 112, the fixing assembly 231 needs to be adjusted to the disengaged position when the assembly 21 or the liquid storage tank 11 is rotated relative to each other. For user convenience, please refer to [link to relevant documentation]. Figures 2-4 as well as Figure 8 As shown, the atomizing device 20 provided in this application also includes an operating member 26 and an elastic reset member 27. The operating member 26 is movably installed on the side of the mounting assembly 21 facing the liquid storage tank 11. One end of the operating member 26 abuts against the fixing assembly 231, and the other end extends to the outside of the electronic atomizing device 100. The operating member 26 is used to push the fixing assembly 231 along the slide 2124 from the contact position to the disengagement position under the action of external force. Along the direction from the contact position to the disengagement position on the side of the mounting component 21 facing the liquid storage tank 11, a top abutment 2125 is also provided at a position away from the disengagement position. The elastic reset member 27 is disposed between the top abutment 2125 and the fixing component 231. During the process of the external force acting on the operating member 26 pushing the fixing component 231 to slide along the slide 2124 from the contact position to the disengagement position, the fixing component 231 compresses the elastic reset member 27, so that the elastic reset member 27 stores elastic potential energy. When the external force acting on the operating member 26 is removed, the elastic reset member 27 releases the elastic potential energy to push the fixing component 231 to slide along the slide 2124 from the disengagement position to the contact position.

[0070] In practical use, if it is necessary to switch different liquid storage components 12 to the contact position, an external force is applied to the operating member 26 to push the fixing component 231 to slide along the slide 2124 from the contact position to the disengagement position, so that the heating part 2321 of the heating element 232 disengages from the liquid storage component 12. Then, by rotating the mounting component 21 and the liquid storage tank 11 relative to each other, different liquid storage chambers 111 (liquid storage components 12) can be switched to the contact position.

[0071] In this embodiment, a positioning protrusion 23112 is also provided on the fixing component 231. Multiple transition cavities 15 are provided on the liquid storage tank 11, each transition cavity 15 corresponding to a liquid storage tank 111. The transition cavity 15 and the positioning protrusion 23112 should be located on the same horizontal plane. When switching between different liquid storage components 12 by rotating the mounting component 21 and the liquid storage tank 11 relative to each other, if the rotation is such that one of the transition cavities 15 is facing or about to face the positioning protrusion 23112, the elastic reset component 27 releases its elastic potential energy, pushing the fixing component 231 to slide from the disengaged position to the contact position. In the contact position, the positioning protrusion 23112 is inserted into the corresponding transition cavity 15, and the liquid storage component 12 to be switched is in the contact position, which is convenient for user operation.

[0072] In this embodiment, the fixing component 231 is further provided with a limiting protrusion 23113 and a limiting groove 2126 is provided on the side wall of the slide 2124. The limiting groove 2126 extends along the length of the slide 2124. After the fixing component 231 is slidably connected to the slide 2124, the limiting protrusion 23113 can be slidably installed in the limiting groove 2126 to prevent the fixing component 231 from disengaging from the slide 2124.

[0073] In this application, the mounting assembly 21 includes a housing 211 and a bracket 212. The housing 211 has an open side. The bracket 212 is installed inside the housing 211 near the open side. The open side of the bracket 212 is connected to the liquid storage tank 11. A slide 2124 is provided on the side of the bracket 212 facing the liquid storage tank 11. An operating member 26 is movably mounted on the bracket 212, and the end of the operating member 26 away from the fixing assembly 231 extends through the housing 211 to the outside for user operation. A mounting groove 2121 is recessed on the side of the bracket 212 facing away from the liquid storage tank 11. An air inlet duct 2122 and a detection air duct 2123 both penetrate the bracket 212, and the detection air duct 2123 communicates with the mounting groove 2121. Figure 2 , Figure 3 as well as Figure 8 As shown, the housing 211 is also provided with an air inlet 2111, which is connected to the air intake passage 2122, and external air can enter the air intake passage 2122 through the air inlet 2111.

[0074] See Figure 2 , Figure 3 as well as Figures 5-7As shown, the liquid storage chamber 11 also includes a tube 13 and multiple spacers 16. The multiple spacers 16 are arranged in a circumferential array around the axis of the liquid storage chamber 11. One side of each spacer 16 is connected to the side wall of the liquid storage chamber 11, and the other side is connected to the tube 13. Along the axis of the liquid storage chamber 11, the length of each spacer 16 is greater than the length of the tube 13, forming an outlet 112 at the portion of the tube 13 that is longer than the spacer 16. Adjacent spacers 16 and the outer wall of the tube 13 enclose a liquid storage cavity 111. The inner cavity of the tube 13 extends to form an atomizing air channel 131. A liquid storage assembly 12 is disposed inside the liquid storage cavity 111, and a portion of the liquid storage assembly 12 is connected to the atomizing air channel 131 through the outlet 112.

[0075] In this embodiment, the liquid storage assembly 12 includes a liquid storage element 121 and a liquid guiding element 122. The liquid guiding element 122 contacts the liquid storage element 121. Both the liquid storage element 121 and the liquid guiding element 122 are installed in the liquid storage chamber 111. Furthermore, the liquid guiding element 122 is positioned close to the atomizing air passage 131, allowing a portion of the liquid guiding element 121 to be exposed through the liquid outlet 112. The sliding assembly 221 reciprocates along the slide rail 2124 between a contact position and a disengagement position to contact or disengage the portion of the liquid guiding element 122 exposed from the liquid outlet 112. The liquid storage element 121 stores the atomizing matrix, and different types of atomizing matrices are stored in the liquid storage elements 121 within different liquid storage assemblies 12. When in contact with the liquid storage element 121, the liquid guiding element 122 can conduct the atomizing matrix stored in the liquid storage element 121.

[0076] Both the liquid storage component 121 and the liquid guiding component 122 can be made of fiber cotton. The liquid storage component 121 stores the atomizing matrix by adsorption, while the liquid guiding component 122 mainly performs the function of guiding the liquid. The liquid guiding component 122 guides the atomizing matrix evenly to the heating element 222 to avoid local dry burning. For example, the cotton core in the liquid guiding component 122 adopts a combination of vertical and horizontal textures to optimize the oil guiding efficiency and prevent leakage.

[0077] It should be understood that both the liquid storage component 121 and the liquid guiding component 122 have capillary forces. The liquid storage component 121 adsorbs and stores the atomizing matrix through capillary forces, and the liquid guiding component 122 adsorbs the atomizing matrix from the liquid storage component 121 through capillary forces. The capillary force of the liquid guiding component 122 should be greater than that of the liquid storage component 121.

[0078] See Figures 9-11As shown, the fixing component 231 includes a support member 2311 and a fixing member 2312. The support member 2311 and the fixing member 2312 are detachably connected, and the fixing member 2312 is slidably connected to the slide rail 2124. The heating part 2321 and the conductive part 2322 are both attached and fixed to the side surface of the support member 2311 facing away from the fixing member 2312. The support member 2311 has a first atomizing window 23111 extending through its thickness direction, and the fixing member 2312 has a second atomizing window 23121 extending through its thickness direction. The first atomizing window 23111 at least partially overlaps with the second atomizing window 23121 to form an atomizing window 233. The air guide channel 2310 is provided on the fixing member 2312 along the height direction of the fixing member 2312. Correspondingly, the clearance notch 23123 is provided on one side of the fixing member 2312 along the thickness direction of the fixing member 2312 and is located above the air guide channel 2310. The positioning protrusion 23112 is provided on the side of the support member 2311 where the heating element 232 and the conductive part 2322 are provided, and the limiting protrusion 23113 is provided on the side of the support member 2311 adjacent to the side where the heating element 232 and the conductive part 2322 are provided.

[0079] In summary, in the electronic atomization device provided in this application, the atomizing airway, the inlet airway, and the detection airway are relatively independent airways, maintaining only a fluid conduction state. The detection airway only has the function of sensing airflow or air pressure changes by the airflow switch. It can be staggered or cross-set relative to the atomizing airway and the inlet airway. The condensate generated by the aerosol flowing through the atomizing airway due to temperature changes is not easy to flow back into the detection airway, which can avoid the problem of corrosion damage to the airflow switch.

[0080] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
