[0048] 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. In some cases, certain operations related to the present application are not shown or described in the specification. 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.

[0049] 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.

[0050] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0051] Atomizing devices can atomize water to humidify the air, or atomize aromatherapy liquids, aromatherapy pastes, etc., to purify or improve air quality. They can also atomize plant leaves, e-liquid, e-liquid paste, etc., to produce edible aerosols. The following examples illustrate atomizing devices that atomize plant leaves, e-liquid, e-liquid, etc., and the atomizing matrix in these examples specifically refers to e-liquid.

[0052] Atomizing devices typically consist of a liquid storage assembly and an atomizing assembly. The atomizing assembly comprises an atomizing tube and an atomizing core. The atomizing core is installed inside the atomizing tube. The liquid storage assembly has a liquid storage chamber, in which the atomizing tube is installed. The atomizing core has an atomization channel, and the atomizing tube has a liquid passage hole that allows the atomizing matrix to enter the atomizing core, where it is heated and atomized to produce an aerosol. The liquid storage assembly has an air inlet communicating with the liquid storage chamber. One end of the atomizing channel is fluid-conducting through the air inlet, while the other end extends to the outside of the liquid storage assembly and communicates with the outside. In actual use, the user draws in air from the other end of the atomizing channel, and the generated aerosol is output through the other end of the atomizing channel.

[0053] When environmental factors (such as a decrease in ambient temperature) cause the internal air pressure of the liquid storage chamber to be lower than the external air pressure of the atomizing device, the atomizing matrix stored in the liquid storage chamber is likely to enter the atomizing core through the liquid hole and then leak from the atomizing core through the air inlet to the outer surface of the atomizing device. This affects not only the amount of aerosol atomization but also the appearance of the product.

[0054] In related technologies, atomizing devices typically employ an oil-wick separation structure to separate the liquid reservoir from the atomizing core when the atomizing device is not in operation, while connecting the liquid reservoir and the atomizing core when in operation, allowing the atomizing matrix in the liquid reservoir to be supplied to the atomizing core. However, the oil-wick separation structure usually requires the user to operate it by pulling, pressing, or rotating at least one of these actions, making it extremely inconvenient to use.

[0055] To address the aforementioned issues, this application provides an atomizing device in which the driving component drives the shielding element to completely or partially block the liquid guiding hole, thereby achieving oil-core separation. This facilitates user operation and reduces the risk of leakage.

[0056] See Figures 1-6 As shown, the atomizing device provided in this application includes a liquid storage chamber 10, an atomizing component 20, and a shielding component 30.

[0057] The liquid storage chamber 10 has a liquid storage cavity 111 inside, which is configured to store the atomizing matrix, wherein the atomizing matrix is ​​e-liquid in liquid form.

[0058] The atomizing assembly 20 includes an atomizing cover 21 and an atomizing core 22. The atomizing cover 21 is disposed inside the liquid storage chamber 111, and the atomizing core 22 is disposed inside the atomizing cover 21. The atomizing cover 21 is configured to position and install the atomizing core 22, ensuring that the atomizing core 22 is installed inside the liquid storage chamber 111. Figure 4 As shown, the side wall of the atomizing cover 21 is provided with a liquid guiding hole 211. The liquid guiding hole 211 connects the inner cavity of the atomizing cover 21 with the liquid storage chamber 111. The liquid guiding hole 211 is configured to allow the atomizing matrix in the liquid storage chamber 111 to enter the interior of the atomizing cover 21, so as to provide the atomizing matrix to the atomizing core 22. The atomizing core 22 can atomize the atomizing matrix into an aerosol by heating.

[0059] In one embodiment of this application, the inner cavity of the atomizing cover 21 is a channel structure that extends along its axial direction, and the aerosol generated by the atomizing core 22 atomizing the atomizing matrix can be output through the inner cavity of the atomizing cover 21.

[0060] like Figure 2 , Figure 4 and Figure 6As shown, the atomizing assembly 20 also includes a liquid storage component 23, which is disposed inside the atomizing cover 21 and located between the atomizing core 22 and the inner wall of the atomizing cover 21. The liquid storage component 23 stores the atomizing matrix that enters the atomizing cover 21 to prevent leakage.

[0061] See Figure 6 As shown, an annular insertion protrusion 115 is also provided in the liquid storage chamber 111 of the liquid storage tank 10, wherein one end of the atomizing cover 21 is inserted into the annular insertion protrusion 115 for positioning and installation in the liquid storage chamber 111.

[0062] To facilitate suction by the user, the atomizing device provided in this application also includes a nozzle 50, which is installed on the liquid storage tank 10. The nozzle 50 has a nozzle channel 51, which is connected to the other end of the atomizing cover 21. The user can use the nozzle 50 to suction, and the aerosol output with the airflow is output through the nozzle channel 51.

[0063] The shielding assembly 30 includes a shielding member 31 and a drive assembly 32. The shielding member 31 is movably mounted on the outer wall of the atomizing cover 21. For example, the shielding member 31 is mounted on the outer wall of the atomizing cover 21 by sliding, rotating or other means. The drive assembly 32 is connected to the shielding member 31 in a driving manner. The drive assembly 32 is configured to drive the shielding member 31 to move relative to the atomizing cover 21 to completely shield or at least partially open the liquid guide hole 211.

[0064] When the shielding member 31 completely covers the liquid guiding hole 211, the liquid storage chamber 111 and the atomizing core 22 are separated. When the shielding member 21 at least partially opens the liquid guiding hole 211, the remaining liquid guiding holes 211 that are not covered by the shielding member 31 are in an open state. The liquid storage chamber 111 and the inner cavity of the atomizing cover 21 are connected through the uncovered liquid guiding holes 211. The atomizing matrix stored in the liquid storage chamber 111 can flow into the inner cavity of the atomizing cover 21 through the uncovered liquid guiding holes 211 to provide to the atomizing core 22. The atomizing core 22 can then heat and atomize the atomizing matrix into an aerosol by heating.

[0065] In some embodiments, the shielding component 30 may be disposed in the liquid storage chamber 111. Alternatively, the shielding component 31 may be disposed in the liquid storage chamber 111, while the driving component 32 may be disposed outside the liquid storage tank 10. The driving component 32 may output linear motion, rotational motion, etc., as long as it can completely shield or at least partially open the liquid guide hole 211 through the shielding component 31.

[0066] In this application, the drive component 32 in the shielding component 30 can be controlled by a switch. The user can operate the switch by pressing, touching, or other means to control the drive component 32 to drive the shielding component 31 to completely shield or at least partially open the liquid guide hole 211. When the shielding component 31 completely shields the liquid guide hole 211, the liquid storage tank 10 and the oil core of the atomizing component 20 can be separated to avoid leakage of the atomizing matrix from the atomizing component 20 due to environmental factors, which is convenient for user operation. When the shielding component 31 at least partially opens the liquid guide hole 211, the liquid storage tank 10 and the oil core of the atomizing component 20 can be combined to provide the atomizing matrix to the atomizing core 22.

[0067] In one embodiment of this application, the liquid storage chamber 10 is further provided with an air inlet chamber 112 that is isolated from the liquid storage cavity 111. The aforementioned atomizing hood 21 is in fluid communication with the air inlet chamber 112, such as... Figure 2 and Figure 4 As shown, a duct hole 113 is provided between the liquid storage chamber 111 and the air inlet chamber 112. The aforementioned annular insertion protrusion 115 protrudes around the duct hole 113 and is located in the liquid storage chamber 111. The atomizing cover 21 is installed in the liquid storage chamber 111 by being inserted into the annular insertion protrusion 115, ensuring that one end of the atomizing cover 21 is connected to the duct hole 113, allowing fluid communication between the atomizing cover 21 and the air inlet chamber 112 through the duct hole 113. The other end of the atomizing cover 21 can extend to the outside of the liquid storage chamber 10. The air inlet chamber 112 ensures that external gas enters and enters the interior of the atomizing cover 21 through the duct hole 113 to generate airflow. The generated aerosol is then output from the other end of the atomizing cover 21 with the airflow.

[0068] like Figure 5 As shown, the liquid storage tank 10 is also provided with an air inlet 114, which is connected to the air inlet chamber 112. The air inlet 114 is used to connect the air inlet chamber 112 with the outside, and outside air can enter the air inlet chamber 112 through the air inlet 114. In actual use, the user can draw air from the other end of the atomizing cover 21. The inner cavity of the atomizing cover 21 creates a pressure difference between the air inlet chamber 112 and the outside of the atomizing device through the air guide hole 113. Then, outside air enters the air inlet chamber 112 through the air inlet 114 and enters the inner cavity of the atomizing cover 21 through the air guide hole 113 to generate airflow. The aerosol generated by the atomizing core 22 can be output from the other end of the atomizing cover 21 with the airflow.

[0069] In this application, the drive component 32 in the shielding component 30 can also be automatically controlled to start or stop. Specifically, the atomizing device provided in this application also includes an airflow sensor 40, which is fluidly connected to the air intake chamber 112. The airflow sensor 40 is communicatively connected to both the atomizing core 22 and the drive component 32. The airflow sensor 40 is configured to respond to changes in air pressure within the air intake chamber 112. After a change in air pressure within the air intake chamber 112, the airflow sensor 40 generates a corresponding control signal to control the atomizing core 22 and the drive component 32 to start or stop.

[0070] When a user inhales through the nozzle 50, allowing outside air to enter the air intake chamber 112 through the air intake port 114, a pressure change occurs within the air intake chamber 112. The airflow sensor 40 senses this pressure change and generates a start signal. This start signal controls the activation of the atomizing core 22 and the drive assembly 32. The drive assembly 32 then drives the shielding member 1 to move relative to the atomizing cover 21, at least partially opening the liquid guide hole 211. This allows the atomizing matrix stored in the liquid storage chamber 111 to enter the inner cavity of the atomizing cover 21 through the liquid guide hole 211 and be supplied to the atomizing core. The atomizing core 22, activated by the start signal, then heats and atomizes the atomizing matrix into an aerosol. When the user completes one inhale, no pressure change occurs within the air intake chamber 112. At this time, the airflow sensor 40 senses the lack of pressure change in the air intake chamber 112 and generates a shut-off signal. This shut-off signal controls the atomizing core 22 and the drive assembly 32 to shut down.

[0071] When the atomizing device is used for the first time, the user's inhalation time through the mouthpiece 50 is very short, resulting in a very short period of time that the liquid guide hole 211 is at least partially open by the shield 31. Consequently, the amount of atomizing matrix entering the atomizing cover 21 through the liquid guide hole 211 is limited, making it difficult for the atomizing core 22 to achieve complete or near-complete saturation, leading to the problem of dry burning and scorching. To address this, the atomizing assembly 20 may also include a delayed starter, whose input and output terminals are communicatively connected to the airflow sensor 40 and the atomizing core 22, respectively. When the airflow sensor 40 senses a pressure change in the air intake chamber 112 and generates a start signal, it controls the drive assembly 32 to start, causing the drive assembly 32 to start before the atomizing core 22. This allows the liquid guide hole 211 to be at least partially open by the shield 31, enabling the atomizing matrix to be supplied to the atomizing core 22 through the liquid guide hole 211, thus achieving complete or near-complete saturation of the atomizing core 22. Afterwards, the start signal controls the delay starter to start the atomizing core 22 after a preset time, which can avoid the problem of dry burning and scorching when the atomizing core 22 is not properly wetted when it is started synchronously with the drive component 32.

[0072] In this application, the airflow sensor 40 senses changes in air pressure within the air intake chamber 112. When a pressure change occurs in the air intake chamber 112 due to user inhalation, the atomizing core 22 and the drive assembly 32 are activated. The drive assembly 32 then moves the shielding member 31 relative to the atomizing cover 21, at least partially opening the liquid guide hole 211. This allows the atomizing matrix to be automatically supplied to the atomizing core 22. Simultaneously with the activation of the drive assembly 32, the atomizing core 22 is activated, heating and atomizing the atomizing matrix to generate an aerosol. When no pressure change occurs in the air intake chamber 112, the atomizing core 22 and the drive assembly 32 are closed, and the drive assembly 32 activates the shielding member 31 to completely block the liquid guide hole 211. Thus, the user can easily separate or reconnect the liquid reservoir 10 and the atomizing assembly 20 via the shielding member 31 during inhalation, preventing leakage of the atomizing matrix from the atomizing assembly 20 due to environmental factors, thus simplifying user operation.

[0073] See Figures 4-6 and Figure 10 As shown, the shielding member 31 has a liquid inlet hole 311. The driving component 32 drives the shielding member 31 to move relative to the atomizing cover 21, so that the liquid inlet hole 311 and the liquid guide hole 211 are misaligned, so that the liquid guide hole 211 is completely shielded by the shielding member 31. Alternatively, the driving component 32 drives the shielding member 31 to move relative to the atomizing cover 21, so that the liquid inlet hole 311 and the liquid guide hole 211 are at least partially aligned, and the liquid guide hole 211 can be at least partially open. When the liquid inlet hole 311 and the liquid guide hole 211 are fully aligned, the liquid guide hole 211 can be fully open. The shielding member 31 can slide relative to the atomizing cover 21 along the axial direction of the atomizing cover 21, or the shielding member 31 can rotate relative to the atomizing cover 21 around the axial direction of the atomizing cover 21. This can achieve the purpose of misaligning the liquid inlet hole and the liquid guide hole 211 of the shielding member 31, or at least partially misaligning the liquid inlet hole 311 and the liquid guide hole 211. When the liquid inlet hole 311 and the liquid guide hole 211 are misaligned, the liquid storage chamber 111 and the atomizing core 22 are in a state of oil-core separation. When the liquid inlet hole 311 and the liquid guide hole 211 are at least partially aligned, the liquid guide hole 211 is in a state of at least partial opening, and the liquid storage chamber 111 and the atomizing core 22 are in a state of oil-core engagement.

[0074] In the above embodiments, the liquid guiding hole 211 and the liquid inlet hole 311 are in a state of misalignment or at least partial alignment when the driving component 32 drives the shielding member 31 to move relative to the atomizing cover 21. In the state of at least partial alignment, the liquid inlet hole 311 can at least partially overlap the liquid guiding hole 211, so that the liquid guiding hole 211 is at least partially open. In the state of misalignment, the shielding member 31 can completely shield the liquid guiding hole 211, so that the liquid guiding hole 211 can achieve a state of complete shielding.

[0075] In this application, the shielding member 31 is rotatably sleeved on the outer wall of the atomizing cover 21, and the driving assembly 32 is used to drive the shielding member 31 to reciprocate between a first preset position and a second preset position relative to the atomizing cover 21. In the first preset position, the liquid inlet hole 311 and the liquid guide hole 211 are misaligned, and the shielding member 31 shields the liquid guide hole 211. In the second preset position, the liquid inlet hole 311 and the liquid guide hole 211 are at least partially aligned, and the liquid guide hole 211 is at least partially open.

[0076] Specifically, with the shielding member 31 completely covering the liquid guiding hole 211, the axis of rotation of the atomizing cover 21 is used as the pivot. In the same cross section perpendicular to the pivot and passing through both the liquid guiding hole 211 and the liquid inlet hole 311, the line connecting the center of the liquid guiding hole 211 and the pivot to the cross section is set as the first straight line, and the line connecting the center of the liquid inlet hole 311 and the pivot to the cross section is set as the second straight line. The angle between the first and second straight lines is 30°. At this time, the liquid inlet hole 311 and the liquid guiding hole 211 are arranged in a clockwise direction. Then, the driving component 32 drives the shielding member 31 to rotate 30° counterclockwise relative to the atomizing cover 21 to reach the second preset position, so that the liquid inlet hole 311 and the liquid guiding hole 211 are fully or almost fully aligned. The drive assembly 32 drives the shielding member 31 to rotate -30° clockwise relative to the atomizing cover 21 to reach a first preset position, which allows the liquid inlet 311 and the liquid guide hole 211 to be misaligned, and the shielding member 31 completely covers the liquid guide hole 211. Correspondingly, when the drive assembly 32 drives the shielding member 31 to rotate between 30° and -30°, the liquid inlet 311 and the liquid guide hole 211 are at least partially aligned, and the liquid guide hole 211 is at least partially open.

[0077] The shielding member 31 is preferably annular in shape and is rotatably fitted onto the outer wall of the atomizing cover 21. Since the atomizing cover 21 is always located in the liquid storage chamber 111, to prevent the atomizing matrix from entering the inner cavity of the atomizing cover 21 through the liquid guide hole 211 via the gap between the shielding member 31 and the outer wall of the atomizing cover 21, see [reference needed]. Figures 2-4 and Figure 6 As shown, the shielding assembly 30 provided in this application also includes a seal 33, which is disposed between the shielding member 31 and the outer wall of the atomizing cover 21. The seal 33 is configured to seal the gap between the shielding member 31 and the atomizing cover 21. When sealing the gap between the shielding member 31 and the atomizing cover 21, the seal 33 can avoid the liquid guide hole 211 and the liquid inlet hole 311, for example, by using a sealing ring.

[0078] In this embodiment, the sealing member 33 is fixedly sleeved on the outer wall of the atomizing cover 21. To improve the sealing effect, the circumferential area of ​​the sealing member 33 is comparable to that of the shielding member 31. Therefore, a drainage hole 331 is provided in the sealing member 33, and the drainage hole 331 and the liquid guiding hole 211 are always at least partially aligned. The driving assembly 21 drives the shielding member 31 to move relative to the atomizing cover 21, so that the liquid inlet hole 311 and the drainage hole 331 are misaligned. The shielding member 31 can completely cover the drainage hole 331, indirectly covering the liquid guiding hole 211. Alternatively, the driving assembly 21 can drive the shielding member 31 to move relative to the atomizing cover 21, so that the liquid inlet hole 311 and the drainage hole 331 are at least partially aligned, indirectly at least partially opening the liquid guiding hole 211.

[0079] See Figure 2 , Figure 6 and Figure 10 and Figure 11 As shown, the shielding component 30 also includes a transmission component 322. The drive component 32 is connected to the shielding member 31 through the transmission component 322. The drive component 32 is configured to drive the shielding member 31 to reciprocate between a first preset position and a second preset position through the transmission component 322. In the first preset position, the liquid inlet hole 311 and the drainage hole 331 are misaligned, and in the second preset position, the liquid inlet hole 311 and the drainage hole 331 are at least partially aligned.

[0080] The drive assembly 32 can be a motor. When the drive assembly 32 is installed inside the liquid storage tank 10, it should be ensured that the drive assembly 32 and the liquid storage chamber 111 are in a sealed state. The transmission assembly 322 can be, for example, a gear set consisting of multiple meshing gears. This gear set is at least meshed with the drive assembly 32 and the shielding member 31. Alternatively, it can consist of a single gear meshing with the shielding member 31. The drive assembly 32 outputs a clockwise or counterclockwise rotational motion, which drives the shielding member 31 to reciprocate between a first preset position and a second preset position via the transmission assembly 322.

[0081] In this embodiment, the transmission assembly 322 includes an eccentric wheel 3221, and the interior of the liquid storage tank 10 is also provided with an installation cavity 116. The installation cavity 116 is connected to the liquid storage tank 111. The drive assembly 32 is fixed inside the installation cavity 116. The eccentric wheel 3221 is sealed and rotatably installed in the installation cavity 116, and the drive assembly 32 is located below the eccentric wheel 3221. In the state of being sealed and rotatably connected between the eccentric wheel 3221 and the cavity wall of the installation cavity 116, it can be ensured that the drive assembly 32 and the liquid storage tank 111 are in a sealed state. The power output end of the drive assembly 32 is coaxially connected to the eccentric wheel 3221. The shielding member 31 is provided with a connecting portion 312 protruding in its radial direction. The eccentric wheel 3221 has an eccentric portion 3223 that is not coaxial with the power output end of the drive assembly 32. The connecting portion 312 is rotatably connected to the eccentric portion 3223. The drive assembly 32 drives the shielding member 31 to reciprocate between a first preset position and a second preset position through the eccentric wheel 3221. The drive assembly 32 outputs reciprocating forward and reverse motion. For example, it outputs a clockwise rotational motion to drive the connecting portion 312 to swing through the eccentric wheel 3221. The angle of the swing can make the shielding member 31 be in the second preset position. When the drive assembly 32 outputs a counterclockwise rotational motion to drive the connecting portion 312 to swing in the opposite direction through the eccentric wheel 3221, the angle of the swing can make the shielding member 31 be in the first preset position.

[0082] To ensure the sealing between the eccentric wheel 3221 and the cavity wall of the mounting cavity 116, the transmission assembly 322 also includes a sealing ring 3222. The sealing ring 3222 is sleeved on the outer periphery of the eccentric wheel 3221 and located between the outer periphery of the eccentric wheel 3221 and the cavity wall of the mounting cavity 116. The sealing ring 3222 can rotate synchronously with the eccentric wheel 3221.

[0083] See Figure 2 As shown, the liquid storage tank 10 is also provided with a mounting groove 117, which is recessed towards the air inlet chamber 112. The mounting groove 117 has a sensing hole 1171 that communicates with the air inlet chamber 112. The airflow sensor 40 is set in the mounting groove 117 and responds to the air pressure change in the air inlet chamber 112 through the sensing hole 1171.

[0084] See Figures 1-3 , Figures 5-9As shown, the liquid storage chamber 10 includes a chamber body 11, an atomizing support 12, and a bottom cover 13. One end of the chamber body 11 has an opening, and the atomizing support 12 is installed in the opening, forming a liquid storage chamber 111 with the inner cavity of the chamber body 11. An air guide hole 113 is formed on the atomizing support 12, and an annular insertion protrusion 115 surrounds the outer periphery of the air guide hole 113 on the side of the atomizing support 11 facing the liquid storage chamber 111. An atomizing cover 21 is fitted onto the annular insertion protrusion 115. The bottom cover 13 is installed on the side of the atomizing support 12 facing away from the liquid storage chamber 111. The bottom cover 13 has an air inlet groove 131, which, together with the side of the atomizing support 12 facing away from the liquid storage chamber 111, forms an air inlet chamber 112. A mounting groove 117 is provided on the side of the bottom cover 13 facing away from the atomizing support 12, and an air inlet 114 is formed in the area of ​​the bottom cover 13 enclosed by the side wall of the air inlet groove 11. The atomizing bracket 12 is also provided with a mounting hole 121, and the bottom cover 13 is also provided with a receiving groove 132. After the bottom cover 13 is installed on the side of the atomizing bracket 12 facing away from the liquid storage chamber 111, the mounting hole 121 and the receiving groove 132 form a mounting cavity 116. The eccentric wheel 3221 is rotatably and sealingly installed in the mounting hole 121 through the sealing member 3222.

[0085] See Figures 12-16 As shown, the atomizing device provided in this application also includes an air regulating component 60, which is fluidly connected to the air inlet 114 and is used to regulate the flow rate of air entering through the air inlet 114, thereby adjusting the suction resistance of the atomizing device when the user inhales, so as to meet the usage needs of different users.

[0086] The air regulating assembly 60 includes an air intake pipe 61, a mounting bracket 62, an adjusting member 63, and an operating member 64. The mounting bracket 62 has an air intake channel 621, and one end of the air intake pipe 61 is connected to one end of the air intake channel 621. The adjusting member 63 is movably mounted on the mounting bracket 62 and covers the other end of the air intake channel 621. The adjusting member 63 is provided with at least two air regulating holes 631. The operating member 64 is mounted on the adjusting member 63. By applying a force to the adjusting member 63 through the operating member 64, the adjusting member 63 moves and adjusts the air regulating holes 631 to connect with the other end of the air intake channel 621. Since the sizes of the air regulating holes 631 are different, the air intake volume of the air intake hole 114 can be adjusted by connecting different air regulating holes 631 with the other end of the air intake channel 621.

[0087] See Figure 16 and Figure 16As shown, the atomizing device provided in this application also includes a housing 70 and a power supply unit 80. The liquid storage tank 10, part of the gas regulating component 60, and the power supply unit 80 are installed inside the housing 70, while the operating part 64 of the gas regulating component 60 is exposed outside the housing 70 for user convenience. The mouthpiece 50 is located outside the housing 70 for easy inhalation. The power supply unit 70 provides the electrical energy required for the operation of the atomizing core 22 and the drive assembly 32.

[0088] In summary, the atomizing device provided by this invention uses an airflow sensor to sense changes in air pressure within the air intake chamber. When a pressure change occurs in the air intake chamber due to user inhalation, the atomizing core and drive assembly are activated. The drive assembly then moves the shielding member relative to the atomizing cover, at least partially opening the liquid guide hole. This allows the atomizing matrix to be automatically supplied to the atomizing core. Simultaneously with the activation of the drive assembly, the atomizing core activates, heating and atomizing the atomizing matrix to produce an aerosol. When there is no pressure change in the air intake chamber, the atomizing core and drive assembly are closed, and the drive assembly completely blocks the liquid guide hole. Thus, the user only needs to separate or connect the liquid reservoir and the atomizing core via the shielding member during inhalation, preventing leakage of the atomizing matrix from the atomizing component due to environmental factors, thus simplifying user operation.

[0089] 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.
