Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomizer and an electronic atomization device. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by solid or liquid particles dispersed and suspended in a gaseous medium. Aerosols can be absorbed by the human body through the respiratory system, providing users with a novel alternative absorption method. Atomizing devices are devices that generate aerosols from stored atomizing media through heating or ultrasound. Atomizing media include liquid, gel, paste, or solid aerosol-generating matrices. Atomizing these media delivers inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] However, when the external temperature or pressure fluctuates, the gas inside the existing atomizing device expands and forces the atomizing medium outward, causing leakage and inconvenience in its use. Utility Model Content

[0004] Therefore, it is necessary to provide an atomizer and an electronic atomizing device to address the problem of leakage when the atomizing device experiences fluctuations in external temperature or pressure.

[0005] An atomizer, the atomizer comprising:

[0006] The atomizing shell has a first liquid storage chamber, a second liquid storage chamber, and a liquid supply channel connecting the first liquid storage chamber and the second liquid storage chamber. The first liquid storage chamber and the second liquid storage chamber are respectively used to store the aerosol generation matrix. The second liquid storage chamber and / or the liquid supply channel are connected to the external atmosphere.

[0007] An atomizing core is at least partially housed within the second liquid storage chamber, the atomizing core being used to atomize the aerosol generating matrix to form an aerosol;

[0008] A sealing plug is inserted into the liquid supply channel; and

[0009] A drive assembly, connected to the sealing plug, is used to drive the sealing plug to reciprocate within the liquid supply channel to open or close the liquid supply channel.

[0010] In one embodiment, the atomizing housing has an air intake channel that connects the external atmosphere to the second liquid storage chamber; or

[0011] The atomizing housing has an air intake channel that connects to the outside atmosphere and the liquid supply channel, and the air intake channel and the liquid supply channel open or close synchronously; or

[0012] The atomizing housing has two air intake channels. One air intake channel connects the outside atmosphere to the second liquid storage chamber, and the other air intake channel connects the outside atmosphere to the liquid supply channel. The air intake channel and the liquid supply channel open or close simultaneously.

[0013] In one embodiment, the atomizing housing includes:

[0014] The main casing is open at one end;

[0015] A top cover, installed within the main housing, defines the first liquid storage chamber between the main housing and the top cover; and

[0016] A sealing element is installed on the side of the top cover facing away from the first liquid storage chamber, and the sealing element and the top cover define a second liquid storage chamber.

[0017] The sealing plug is connected to the sealing element.

[0018] In one embodiment, the seal has a connecting portion that surrounds the sealing plug circumferentially, the connecting portion being capable of recoverable deformation under external force.

[0019] In one embodiment, the end of the sealing plug extending into the liquid supply channel is tapered, and the outer diameter of the end of the sealing plug extending into the liquid supply channel gradually increases from the end near the first liquid storage cavity to the end away from the first liquid storage cavity.

[0020] In one embodiment, the driving component includes:

[0021] An electromagnetic coil is located outside the atomizing housing;

[0022] An electromagnet push rod is inserted at one end into the electromagnetic coil and at the other end into the sealing plug. The electromagnet push rod moves under the magnetic field of the electromagnetic coil to open the liquid supply channel.

[0023] In one embodiment, the drive assembly further includes a reset member abutting between the electromagnetic coil and the electromagnet push rod, wherein the electromagnet closes the liquid supply channel under the push of the reset member.

[0024] In one embodiment, the capacity V of the first liquid storage chamber is ≥ 6 ml.

[0025] In one embodiment, the duration and frequency at which the sealing plug opens the liquid supply channel are positively correlated with the viscosity of the aerosol generating matrix.

[0026] An electronic atomizing device includes the aforementioned atomizer, and the electronic atomizing device further includes a battery assembly, the battery assembly being coupled to one end of the atomizer and electrically connected to the atomizer.

[0027] In the aforementioned atomizer, since the liquid supply channel is normally closed when the atomizer is not in operation, the aerosol generating matrix in the first liquid storage chamber will not flow out even if the external temperature or pressure fluctuates, and the atomizer will not leak. Moreover, since the opening and closing of the liquid supply channel is not affected by the volume of the first liquid storage chamber, the capacity of the first liquid storage chamber can be further increased to accommodate more aerosol generating matrix while keeping the first liquid storage chamber visible.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] See Figure 1 This application provides an electronic atomizing device 100 for atomizing a medium to generate an aerosol for user use. The atomizing medium includes, but is not limited to, liquid materials such as medicines and oils used for medical, health, or beauty purposes. The atomization method includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, laser heating, or microwave heating.

[0045] The electronic atomizing device 100 includes an atomizer 20 and a battery assembly 40. The battery assembly 40 is connected to one end of the atomizer 20 and electrically connected to the atomizer 20. The atomizer 20 is used to store the atomizing medium and heats and atomizes the atomizing medium under the power of the battery assembly 40.

[0046] In the following embodiments, the height direction of the electronic atomizing device 100 is defined as the first direction (i.e., Figure 2The Z-direction in the middle), the length direction of the electronic atomizing device 100 is the second direction (i.e., Figure 2 In the X direction, the atomizer 20 and the battery assembly 40 are coupled to each other in the first direction. In a preferred embodiment, the first direction and the second direction are perpendicular to each other.

[0047] As described in the background section, existing electronic atomizing devices often leak when there are fluctuations in external temperature or pressure, especially large-volume electronic atomizing devices, which can experience severe leakage when there are fluctuations in external temperature or pressure.

[0048] Currently, there are two common methods to prevent leakage. One method involves placing a reservoir inside the e-cigarette device and connecting it to the outside atmosphere. This eliminates the pressure difference between the inside and outside of the device, preventing leakage. However, with this method, the user cannot observe the remaining liquid level inside the device. The other method involves placing a catcher based on the e-cigarette's fill volume. Leaking aerosol generator material is caught by the catcher, preventing it from flowing outside the device. While this method allows the user to directly observe the remaining liquid level, it causes the aerosol generator material level to drop rapidly in the event of a leak.

[0049] For the above technical issues, please refer to Figure 2 , Figure 3 The atomizer 20 of this application includes an atomizing housing 21, an atomizing core 22, a sealing plug 23, and a driving assembly 24.

[0050] The atomizing housing 21 has a first liquid storage chamber 21a, a second liquid storage chamber 21b, and a liquid supply channel 216b connecting the first liquid storage chamber 21a and the second liquid storage chamber 21b. The first liquid storage chamber 21a and the second liquid storage chamber 21b are respectively used to store the aerosol generation matrix, and the second liquid storage chamber 21b and / or the liquid supply channel 216b are connected to the external atmosphere.

[0051] The atomizing core 22 is at least partially housed within the second liquid storage chamber 21b, and is used to absorb and heat the atomized aerosol matrix from the second liquid storage chamber 21b to form an aerosol.

[0052] A sealing plug 23 is inserted into the liquid supply channel 216b. Specifically, in this embodiment, one end of the sealing plug 23 is located in the second liquid storage chamber 21b, and the other end is inserted into the liquid supply channel 216b. A drive assembly 24 is connected to the sealing plug 23 and is used to drive the sealing plug 23 to reciprocate within the liquid supply channel 216b to open or close the liquid supply channel 216b.

[0053] When the atomizer 20 is not in operation, the sealing plug 23 closes the liquid supply channel 216b, and the first liquid storage chamber 21a is disconnected from the second liquid storage chamber 21b. Therefore, when the first liquid storage chamber 21a is pressurized due to external temperature or pressure fluctuations, the aerosol generation matrix in the first liquid storage chamber 21a cannot enter the second liquid storage chamber 21b due to the obstruction of the sealing plug 23.

[0054] When the atomizer 20 is in operation, the sealing plug 23 can open the liquid supply channel 216b to connect the first liquid storage chamber 21a and the second liquid storage chamber 21b. The aerosol generation matrix in the first liquid storage chamber 21a can enter the second liquid storage chamber 21b through the liquid supply channel 216b. At the same time, external air can enter the first liquid storage chamber 21a through the second liquid storage chamber 21b or the liquid supply channel 216b to balance the air pressure in the first liquid storage chamber 21a.

[0055] In the aforementioned atomizer 20, since the liquid supply channel 216b is normally closed when the atomizer 20 is not in operation, the aerosol generating matrix in the first liquid storage chamber 21a will not flow out even if the external temperature or pressure fluctuates, ensuring that the atomizer 20 does not leak. Furthermore, since the opening and closing of the liquid supply channel 216b is not affected by the capacity of the first liquid storage chamber 21a, but rather depends entirely on the movement of the sealing plug 23 controlled by the drive assembly 24, the capacity of the first liquid storage chamber 21a can be further increased to store more aerosol generating matrix while maintaining visibility. Specifically, in this application, the capacity V of the first liquid storage chamber 21a is ≥ 6 ml.

[0056] Please continue reading. Figure 2 and Figure 3 In some embodiments, the atomizing housing 21 has an air intake channel 216c, which is used to realize the exchange of internal and external gases of the atomizer 20, thereby balancing the internal and external air pressure of the atomizer 20.

[0057] In one specific embodiment, the atomizing housing 21 has only one air intake channel 216c, which connects the external atmosphere with the second liquid storage chamber 21b. Therefore, the external atmosphere and the second liquid storage chamber 21b are always in communication. External air can enter the second liquid storage chamber 21b through the air intake channel 216c and then enter the first liquid storage chamber 21a through the liquid supply channel 216b.

[0058] In other embodiments, the atomizing housing 21 has only one air inlet channel 216c, which connects the external atmosphere and the liquid supply channel 216b. The air inlet channel 216c and the liquid supply channel 216b open or close simultaneously. Therefore, the second liquid storage chamber 21b is not connected to the external atmosphere, and external air directly enters the first liquid storage chamber 21a through the liquid supply channel 216b. Since the aerosol generating matrix in the second liquid storage chamber 21b is continuously consumed and under negative pressure when the electronic atomizing device 100 is in operation, this facilitates the entry of the aerosol generating matrix from the first liquid storage chamber 21a into the second liquid storage chamber 21b.

[0059] In some other embodiments, the atomizing housing 21 has two air intake channels 216c. One air intake channel 216c connects the external atmosphere to the first liquid storage chamber 21a, and the other air intake channel 216c connects the external atmosphere to the liquid supply channel 216b. The air intake channel 216c and the liquid supply channel 216b are opened or closed simultaneously. In this way, on the one hand, the external atmosphere and the second liquid storage chamber 21b are always in communication, and external air can enter the second liquid storage chamber 21b through the air intake channel 216c and then enter the first liquid storage chamber 21a through the liquid supply channel 216b. On the other hand, when the electronic atomizing device 100 is in working condition, external air can also directly enter the first liquid storage chamber 21a through the liquid supply channel 216b.

[0060] In some embodiments, the atomizer 20 further includes a liquid storage element 25, which is formed of a porous material such as liquid storage cotton. The liquid storage element 25 fills the second liquid storage chamber 21b and has a shape similar to that of the second liquid storage chamber 21b. It is used to absorb the aerosol generation matrix in the second liquid storage chamber 21b, thereby preventing the aerosol generation matrix in the second liquid storage chamber 21b from leaking through the air inlet channel 216c.

[0061] It is understandable that when the atomizing housing 21 has only one air intake channel 216c connecting the liquid supply channel 216b to the external atmosphere, there is no risk of leakage in the second liquid storage chamber 21b, so there is no need to install a liquid storage component 25 in the second liquid storage chamber 21b.

[0062] Please refer to Figure 2 to... Figure 4 As shown, in some embodiments, the atomizing housing 21 includes a main housing 212, an exhaust pipe 214, a top cover 216, and a seal 218.

[0063] The main housing 212 is a hollow shell structure with one open end, including a closed end and an open end disposed opposite each other in a first direction, with the closed end located at the end of the main housing 212 away from the battery assembly 40. The main housing 212 is formed of a transparent or translucent material, thereby facilitating the user's observation of the liquid level in the first liquid storage chamber 21a. An exhaust pipe 214 is located inside the main housing 212 and close to the open end of the main housing 212. One end of the exhaust pipe 214 is connected to the closed end of the main housing 212, and the other end of the exhaust pipe 214 extends toward the open end of the main housing 212. An exhaust channel 214a extending in the first direction is formed inside the exhaust pipe 214, and the exhaust channel 214a penetrates the closed end of the main housing 212 to connect with the external atmosphere.

[0064] The top cover 216 is installed inside the main housing 212 and close to the opening end of the main housing 212. The top cover 216 includes a top wall and a side wall. The side wall extends from the edge of the top wall toward the opening end of the main housing 212. The top wall and the main housing 212 together form a first liquid storage cavity 21a surrounding the exhaust pipe 214 in a circumferential direction. The top wall of the top cover has a connecting port 216a and a liquid supply channel 216b. The connecting port 216a and the liquid supply channel 216b are respectively connected to the first liquid storage cavity 21a. The connecting port 216a and the liquid supply channel 216b are spaced apart in a second direction. One end of the exhaust pipe 214 extends into the connecting port 216a in a first direction. One end of the air intake channel 216c extends from the side wall of the top cover away from the top wall of the top cover in a first direction to the top wall of the top cover. The other end of the air intake channel 216c is formed in the top wall of the top cover and extends in a second direction.

[0065] The sealing element 218 is installed on the side of the top cover 216 facing away from the first liquid storage chamber 21a. The edge of the sealing element 218 is sealed to the top cover side wall of the top cover 216. The sealing element 218 and the top cover 216 define a second liquid storage chamber 21b. The first liquid storage chamber 21a and the second liquid storage chamber 21b are arranged adjacent to each other in the first direction.

[0066] In some embodiments, the atomizing core 22 includes an atomizing tube 221, a heating element 223, and a liquid guiding element 225.

[0067] Specifically, the atomizing tube 221 is a hollow tubular structure extending along a first direction. One end of the atomizing tube 221 is located inside the first liquid storage chamber 21a and sleeved outside the exhaust pipe 214. The other end of the atomizing tube 221 extends into the second liquid storage chamber 21b through the connecting opening 216a of the top wall of the top cover. At least one liquid inlet is provided on the tube wall at the end of the atomizing tube 221 located in the second liquid storage chamber 21b. The heating element 223 is housed in the end of the atomizing tube 221 located in the second liquid storage chamber 21b. The heating element 223 is formed by winding a structure such as a metal mesh or metal wire around the first direction, and the heating element 223 is electrically connected to the battery assembly 40. The liquid guiding component 225 is housed in the atomizing tube 221 and covers the heating element 223 circumferentially.

[0068] Thus, the aerosol generating matrix in the second liquid storage chamber 21b enters the atomizing tube 221 through the liquid inlet on the atomizing tube 221, and is then guided to the heating element 223 by the liquid guide 225. The heating element 223 heats the atomized aerosol generating matrix under the action of the electrical energy of the battery assembly 40, and the aerosol generated by atomization flows out through the exhaust channel 214a.

[0069] The sealing plug 23 protrudes from the side of the sealing member 218 facing the first liquid storage chamber 21a. Therefore, one end of the sealing plug 23 is located in the second liquid storage chamber 21b, and the other end of the sealing plug 23 extends into the liquid supply channel 216b.

[0070] As one embodiment, the sealing member 218 is provided with a connecting portion 2181 that surrounds the sealing plug 23 in the circumferential direction. The connecting portion 2181 is formed of a soft material such as silicone. The cross-section of the connecting portion 2181 is in the shape of an arc or a wave. Therefore, the connecting portion 2181 can undergo recoverable deformation under the action of external force. When the sealing plug 23 moves under the drive of the drive assembly 24, the connecting portion 2181 can deform accordingly to achieve the function of dynamic isolation and sealing, and prevent leakage of the aerosol generation matrix in the second liquid storage chamber 21b.

[0071] In some embodiments, the end of the sealing plug 23 extending into the liquid supply channel 216b is tapered, and the outer diameter of the end of the sealing plug 23 extending into the liquid supply channel 216b gradually increases from the end near the first liquid storage chamber 21a to the end away from the first liquid storage chamber 21a. Preferably, the end of the sealing plug 23 extending into the liquid supply channel 216b is tapered with a pointed tip. Therefore, when the sealing plug 23 switches from the state of opening the liquid supply channel 216b to the state of closing the liquid supply channel 216b, the tapered sealing plug 23 can push the air bubbles generated by ventilation towards the first liquid storage chamber 21a, thereby preventing air bubbles from getting stuck in the liquid supply channel 216b and reducing the possibility of drawing out charred residue. It is understood that the shape of the sealing plug 23 is not limited to this and can be set as needed to meet different sealing requirements.

[0072] The atomizer 20 also includes a mounting bracket 26, which is mounted outside one end of the open end of the main housing 212. The battery assembly 40 is mounted to one end of the atomizer 20 via the mounting bracket 26. The drive assembly 24 includes an electromagnetic coil 241 and an electromagnet push rod 243. The electromagnetic coil 241 is mounted inside the mounting bracket 26 and located outside the atomizing housing 21. The electromagnetic coil 241 is electrically connected to the battery assembly 40 and can generate a magnetic field under the power of the battery assembly 40. The electromagnet push rod 243 is a rod-shaped structure extending along a first direction. One end of the electromagnet push rod 243 is inserted into the electromagnetic coil 241, and the other end of the electromagnet push rod 243 is connected to a sealing plug 23. The electromagnet push rod 243 moves under the magnetic field of the electromagnetic coil 241 to open the liquid supply channel 216b.

[0073] Furthermore, the drive assembly 24 also includes a reset member 245, which abuts against the electromagnetic coil 241 and the electromagnet push rod 243. Under the push of the reset member 245, the electromagnet push rod 243 drives the sealing plug 23 to close the liquid supply channel 216b. Since the reset member 245 provides a certain force to the sealing plug 23 through the electromagnet push rod 243, the sealing plug 23 can overcome the pressure applied by the first liquid storage chamber 21a and close the liquid supply channel 216b.

[0074] In some embodiments, the sealing plug 23 has a mounting hole at one end facing away from the first liquid storage chamber 21a, and the wall of the mounting hole has a limiting protrusion 232 extending circumferentially. One end of the electromagnet push rod 243 has a limiting groove 243a extending circumferentially. The end of the electromagnet push rod 243 with the limiting groove 243a is inserted into the mounting hole along a first direction, and the limiting protrusion 232 is embedded in the limiting groove 243a, so that the electromagnet push rod 243 and the sealing plug 23 are fixedly connected to each other in the first direction.

[0075] Thus, when the electronic atomizing device 100 is in a non-operating state, the electromagnetic coil 241 is not energized, and the electromagnet push rod 243 closes the liquid supply channel 216b under the resistance of the reset member 245. When the electronic atomizing device 100 is in an operating state, the electromagnetic coil 241 is energized and generates a magnetic field. Under the action of the magnetic field, the electromagnet push rod 243 moves against the force of the reset member 245 to open the liquid supply channel 216b. When the electronic atomizing device 100 stops operating, the electromagnetic field of the electromagnetic coil 241 disappears, and the electromagnet push rod 243 moves in the opposite direction under the push of the reset member 245 to close the liquid supply channel 216b again.

[0076] Please combine Figure 5 As shown, the force analysis of the sealing plug 23 shows that when the liquid supply channel 216b is in a closed state, the diameter of the bottom surface of the exposed conical surface of the sealing plug 23 is d, and the cone angle of the top of the sealing plug 23 is θ. Therefore, the force-bearing area of ​​the sealing plug 23 is S = πd.2 / 4sin(θ / 2). Since the pressure P1 exerted by the aerosol matrix filling the first liquid storage chamber 21a on the sealing plug 23 is entirely in the normal direction, its horizontal component cancels each other out, and the vertical downward component F 腔 =P1·S·sin(θ / 2). When the pressure in the first liquid storage chamber 21a rises to P2, it is necessary to ensure the elastic force F of the reset member 245. 弹 >P2·S·sin(θ / 2), while ensuring the electromagnetic force F generated after the electromagnetic coil 241 is energized. 磁 >F 弹 The value of θ ranges from 60° to 120°.

[0077] It is understandable that, in order to ensure smooth liquid supply, the control logic of the drive component 24 needs to be determined based on factors such as the viscosity of the aerosol generating matrix. Since the duration and frequency of the sealing plug 23 opening the liquid supply channel 216b are positively correlated with the viscosity of the aerosol generating matrix, the higher the viscosity of the aerosol generating matrix, the longer the sealing plug 23 opens the liquid supply channel 216b, and / or the higher the frequency of the sealing plug 23 opening the liquid supply channel 216b.

[0078] like Figure 2 , Figure 3 as well as Figure 6 As shown, the electronic atomizing device 100 also includes a processor 60, which is installed inside the battery assembly 40. The processor 60 has a timer inside it. The processor 60 is used to control the battery assembly 40 to supply power to the electromagnetic coil 241 of the atomizing core 22 and the driving assembly 24, and to precisely control the duration of the battery assembly 40 supplying power to the electromagnetic coil 241 and the interval between two power supplies through the timer.

[0079] When the electronic atomizing device 100 is in a non-operating state, the battery assembly 40 does not supply power to the electromagnetic coil 241, and the electromagnet push rod 243 closes the liquid supply channel 216b under the resistance of the reset member 245. When the electronic atomizing device 100 is in an operating state, the processor 60 controls the battery assembly 40 to supply power to the electromagnetic coil 241 at a certain frequency. After the electromagnetic coil 241 is energized, it forms a magnetic field. Under the action of the magnetic field, the electromagnet push rod 243 moves against the force of the reset member 245 to open the liquid supply channel 216b. When the electronic atomizing device 100 switches to an operating state, the processor 60 controls the battery assembly 40 to stop supplying power to the electromagnetic coil 241. The magnetic field formed by the electromagnetic coil 241 disappears, and the electromagnet push rod 243 moves in the opposite direction under the push of the reset member 245 to close the liquid supply channel 216b again.

[0080] After the electronic atomizing device 100 switches to the working state:

[0081] The processor 60 controls the battery assembly 40 to supply power to the electromagnetic coil 241. After the electromagnetic coil 241 is energized, it forms a magnetic field. Under the action of the magnetic field, the electromagnet push rod 243 moves against the force of the reset member 245 to open the liquid supply channel 216b.

[0082] When the opening time of the liquid supply channel 216b reaches the preset opening time, the processor 60 controls the battery assembly 40 to stop supplying power to the electromagnetic coil 241, the magnetic field formed by the electromagnetic coil 241 disappears, and the electromagnet push rod 243 moves in the opposite direction under the push of the reset member 245 to close the liquid supply channel 216b again.

[0083] When the closing time of the liquid supply channel 216b reaches the preset closing time, the processor 60 controls the battery assembly 40 to supply power to the electromagnetic coil 241. After the electromagnetic coil 241 is energized, it forms a magnetic field. Under the action of the magnetic field, the electromagnet push rod 243 moves against the force of the reset member 245 to open the liquid supply channel 216b.

[0084] The above process is repeated until the electronic atomizing device 100 switches to a non-working state.

[0085] The aforementioned atomizer 20 and electronic atomizing device 100, by providing a first liquid storage chamber 21a, a second liquid storage chamber 21b, and a liquid supply channel 216b between them that can be opened and closed by external force, can effectively isolate the aerosol generation matrix and the atomizing core 22, effectively solve the serious leakage problem of the electronic atomizing device 100 with a large liquid volume, and effectively prevent the electronic atomizing device 100 from experiencing a decrease in taste in the later stages of use.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
