Detailed Implementation

[0045] 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.

[0046] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0047] 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).

[0048] In related technologies, the atomizing device is equipped with a liquid storage chamber for storing the atomizing matrix and a liquid inlet for supplying the atomizing matrix to the atomizing component. The atomizing matrix is ​​the aerosol generating matrix. The liquid inlet is always connected to the liquid storage chamber. The atomizing matrix can directly enter the atomizing component through the liquid inlet, which leads to leakage when too much atomizing matrix enters the atomizing component, affecting the user experience.

[0049] Based on this, this application movably mounts the atomizing component onto the housing component and includes a driving component. The driving component comprises a driving body, which has at least a first form and a second form. The driving body switches between the first and second forms in response to temperature. The atomizing component switches between a first and a second position in response to the form change of the driving body. When it is necessary for the atomizing matrix in the storage chamber to enter the atomizing component, the driving body can be controlled to assume the second form in response to temperature, and the atomizing component is in the second position in response to the form change of the driving body. When it is not necessary for the atomizing matrix in the storage chamber to enter the atomizing component, the driving body can be controlled to switch from the second form to the first form in response to temperature, and the atomizing component is in the first position in response to the form change of the driving body, thereby preventing the atomizing matrix from entering the atomizing component, which helps to improve the leakage problem and enhance the user experience.

[0050] The following describes some embodiments of the atomizing device provided in this application with reference to the accompanying drawings.

[0051] Please see Figures 1 to 4 This application provides an atomizing device, including a housing assembly 1, an atomizing assembly 2, a driving assembly 8, and other functional components as needed, which are described in detail below.

[0052] like Figure 2 , Figure 3As shown, in this embodiment, the housing assembly 1 has a liquid storage chamber 101 for storing the atomizing matrix, and the atomizing assembly 2 is used to heat the atomizing matrix to generate an aerosol. The atomizing assembly 2 has a liquid inlet 201 and is movably disposed on the housing assembly 1. During the movement stroke of the atomizing assembly 2, the atomizing assembly 2 has a first position and a second position. In the first position, the liquid inlet 201 is isolated from the liquid storage chamber 101, and in the second position, the liquid inlet 201 is connected to the liquid storage chamber 101.

[0053] It is understood that the liquid storage chamber 101 in this application is located inside the housing assembly 1. It can be formed by an integrally formed liquid storage space within the housing assembly 1, sealed by a sealing method; or, it can be a liquid storage component, such as a liquid storage bottle, directly fixed inside the housing assembly 1, having an outlet port communicating with the liquid inlet 201 of the atomizing assembly 2. The housing assembly 1 in this embodiment may be made of at least one of metal or plastic. The housing assembly 1 may be assembled from two or more parts, for example, it may include an upper mouthpiece and a lower base, or it may include an outer shell and an inner shell fixed within the outer shell. The atomizing assembly 2 in this embodiment has a first position and a second position, and the movement of the atomizing assembly 2 within the housing assembly 1 allows switching between the first and second positions. This embodiment does not limit the specific structure of the atomizing assembly 2 that allows it to be movably positioned within the housing assembly 1; any structure that enables the heating and atomizing function of the atomizing assembly 2 and allows for position switching of the atomizing assembly 2 is acceptable. The atomizing matrix in this embodiment may be a medicinal liquid, e-liquid, or other atomizable liquid matrix. In this embodiment, the liquid inlet 201 can be, but is not limited to, a perforated structure.

[0054] In this embodiment, as Figure 2 , Figure 3 As shown, the driving component 8 includes a driving body 801, which has at least a first form and a second form. The driving body 801 switches between the first form and the second form in response to temperature. The atomizing component 2 switches between a first position and a second position in response to the form switching of the driving body 801.

[0055] It is understood that the driving body 801 has a first form and a second form, and the driving body 801 can switch between the first form and the second form through temperature control. For example, the temperature of the driving body 801 can be controlled to rise to a target range so that the driving body 801 presents the second form; the temperature of the driving body 801 can be controlled to fall to a target range so that the driving body 801 switches from the second form to the first form. This embodiment does not limit the specific implementation of the temperature control of the driving body 801, and can realize its temperature change and form switching. In this embodiment, the atomizing component 2 can respond to the form switching of the driving body 801, that is, as the form of the driving body 801 changes, the atomizing component 2 will move accordingly, thereby realizing the switching between the first position and the second position. The driving component 8 and the atomizing component 2 can be directly connected, or they can also be connected through an intermediate component to realize the response of the atomizing component 2 to the deformation of the driving body 801. In this embodiment, there are no restrictions on the specific shape changes of the driving body 801. For example, it can be a change in length in a certain direction; or a change in overall volume; or a change in overall shape, such as a curved arc or a protrusion in certain parts, etc.

[0056] The atomizing device provided in this embodiment has an atomizing component 2 movably disposed on the housing component 1. Within its travel range, the atomizing component 2 has a first position and a second position. In the first position, the liquid inlet 201 is isolated from the liquid storage chamber 101. In the second position, the liquid inlet 201 is connected to the liquid storage chamber 101. The driving component 8 includes a driving body 801, which has at least a first form and a second form. The driving body 801 switches between the first and second forms in response to temperature. The atomizing component 2 switches between the first and second positions in response to the form switching of the driving body 801. When the atomizing matrix in the liquid storage chamber 101 needs to enter the atomizing component 2, the driving body 801 can be controlled to take on the second form in response to temperature, and the atomizing component 2 is in the second position in response to the form switching of the driving body 801. When the atomizing matrix in the storage chamber 101 is not required to enter the atomizing component 2, the driving body 801 can be controlled to switch from the second form to the first form in response to the temperature, and the atomizing component 2 is in the first position in response to the form switch of the driving body 801, so as to prevent the atomizing matrix from entering the atomizing component 2, which helps to improve the leakage problem and improve the user experience.

[0057] In one embodiment, such as Figure 2 , Figure 3As shown, the driving assembly 8 also includes a stabilizing elastic element 802, the driving body 801 is a memory elastic element, and the atomizing device also includes a transmission element 4. The stabilizing elastic element 802 is used to apply a restoring force to the transmission element 4; the memory elastic element is used to apply a driving force to the transmission element 4. The driving force of the driving body 801 in the first configuration is different from the driving force in the second configuration. When the driving body 801 is in the first configuration, the resultant force of the restoring force and the driving force, through the transmission element 4, limits the atomizing assembly 2 to a first position, or the resultant force of the restoring force and the driving force, through the transmission element 4, drives the atomizing assembly 2 to move to the first position. When the driving body 801 is in the second configuration, the resultant force of the restoring force and the driving force, through the transmission element 4, limits the atomizing assembly 2 to a second position, or the resultant force of the restoring force and the driving force, through the transmission element 4, drives the atomizing assembly 2 to move to the second position. In this embodiment, the driving body 801 is an elastic element, and its elasticity can serve as a driving force. The driving force of the driving body 801 in the first state is different from that in the second state. That is, the change in shape of the driving body 801 will cause a change in the elasticity of the driving body 801, thereby realizing a change in the driving force. The driving component 8 includes a stabilizing elastic element 802, which applies a reset force to the transmission component 4, mainly to reset the atomizing component 2, which helps to prevent the atomizing component 2 from jamming and improves the stability of the atomizing component 2's movement. In some embodiments, since the driving body 801 itself can switch between the first and second states in response to temperature, only the shape switching of the driving body 801 can drive the reset of the atomizing component 2. In this case, it is not necessary to provide a stabilizing elastic element 802 for reset.

[0058] In one embodiment, the driving component 8 further includes a stabilizing elastic element 802. When the driving body 801 is a memory elastic element, the direction of the driving force and the direction of the reset force can be opposite. When the driving body 801 is in the first configuration, such as... Figure 3 As shown, the driving body 801 applies a first driving force to the transmission component 4. This first driving force is less than the reset force. The driving assembly 8, through the transmission component 4, limits the atomizing component 2 to a first position, or drives the atomizing component 2 to move to the first position. When the driving body 801 is in the second configuration, as shown... Figure 2As shown, the driving body 801 applies a second driving force to the atomizing component 2. The second driving force is greater than the reset force. The driving component 8, through the transmission member 4, limits the atomizing component 2 to a second position, or drives the atomizing component 2 to move to the second position. In this embodiment, the direction of the driving force is opposite to the direction of the reset force. Therefore, the driving force difference between the first and second states of the driving body 801 can be used to reliably drive and reset the atomizing component 2. When the first driving force is less than the reset force, the direction of the resultant force of the reset force and the driving force is the same as the direction of the reset force. The driving component 8 can drive the atomizing component 2 to the first position through the transmission member 4. After reaching the first position, the atomizing component 2 can be limited to the first position through the transmission member 4, so as to isolate the liquid inlet 201 from the liquid storage chamber 101, which helps to prevent leakage of the atomizing matrix. The second driving force is greater than the reset force. At this time, the direction of the resultant force of the reset force and the driving force is the same as the direction of the driving force. The driving component 8 can drive the atomizing component 2 to move to the second position through the transmission component 4. After it reaches the second position, the atomizing component 2 can be fixed in the second position through the transmission component 4 so that the liquid inlet 201 is connected to the liquid storage chamber 101. At this time, the atomizing matrix can be replenished. In this embodiment, the direction of the driving force and the direction of the reset force can be completely opposite or approximately opposite.

[0059] In some embodiments, both the first driving force and the second driving force may be greater than the reset force, and the first driving force may be less than the second driving force. In the first configuration, the driving body 801 compresses the stabilizing elastic element 802, and the atomizing component 2 is in the first position. When the driving body 801 switches to the second configuration, the driving force of the driving body 801 increases, further compressing the stabilizing elastic element 802 and pushing the atomizing component 2 to the second position, thereby enabling the switching between the first and second positions of the atomizing component 2.

[0060] In one embodiment, such as Figures 2-4 As shown, the transmission component 4 is fixedly connected to the atomizing component 2. The atomizing device also includes an inner support 6 fixed relative to the housing component 1. The inner support 6 is provided with a support portion 601, which is located between the atomizing component 2 and the driving component 8. The inner support 6 is a fixed support portion 601 within the housing component 1. Directly setting the support portion 601 on the inner support 6 simplifies the device structure and facilitates manufacturing and assembly. In this embodiment, the transmission component 4 is also provided with a force-bearing portion 401 that extends radially. The stabilizing elastic component 802 is disposed in a compressed state between the force-bearing portion 401 and the support portion 601. One end of the stabilizing elastic component 802 abuts against or is fixed to the force-bearing portion 401, and the other end abuts against or is fixed to the support portion 601. The force-bearing portion 401 protrudes radially, which facilitates the abutment of the stabilizing elastic component 802 on the force-bearing portion 401. In this embodiment, radial refers to the diameter direction of the stabilizing elastic component 802. The stabilizing elastic element 802 is in a compressed state, thereby applying a restoring force to the force-bearing part 401.

[0061] In this embodiment, as Figure 2 , Figure 3 As shown, a bottom support portion fixed relative to the housing assembly 1 is provided inside the housing assembly 1. The memory elastic element is disposed in a compressed state on the side of the force-receiving portion 401 away from the stabilizing elastic element 802. One end of the memory elastic element abuts or is fixed to the force-receiving portion 401, and the other end abuts or is fixed to the bottom support portion. The bottom support portion is a fixed component inside the housing assembly 1. The memory elastic element is compressed between the bottom support portion and the force-receiving portion 401, thereby allowing the memory elastic element to apply a driving force to the force-receiving portion 401.

[0062] In one embodiment, such as Figures 2-4 As shown, the atomizing device includes a circuit board 9 disposed within the housing assembly 1, with the circuit board 9 located on the side of the transmission member 4 away from the atomizing assembly 2. The circuit board 9 forms a bottom support portion, and a memory elastic element is electrically connected to the circuit board 9. The circuit board 9 controls the operation of the atomizing core 205, and since it also serves as a bottom support portion, it also supports the memory elastic element, eliminating the need for additional support components and simplifying the structure.

[0063] In one embodiment, such as Figure 2 , Figure 3 As shown, the circuit board 9 has a first guide hole 901, and the transmission member 4 also includes a rod-shaped guide portion 402. One end of the guide portion 402, away from the atomizing component 2, is movably inserted into the first guide hole 901. The housing assembly 1 has a bottom 106 away from the liquid storage chamber 101, and a clearance space 7 is provided between the bottom 106 and the circuit board 9 to accommodate the guide portion 402 extending from the first guide hole 901. Alternatively, the bottom 106 has a support protrusion 102, which protrudes from the inner side of the bottom 106, and the circuit board 9 is supported on the support protrusion 102 to provide a clearance space 7 between the circuit board 9 and the inner side of the bottom 106. The clearance space 7 between the bottom 106 and the circuit board 9 allows the guide portion 402 extending from the first guide hole 901 to be inserted when the transmission member 4 is pushed and moved by the driving assembly 8; that is, the clearance space 7 avoids interference. In some embodiments, the clearance space 7 may be unnecessary when the guide portion 402 is not provided.

[0064] In one embodiment, such as Figures 2-4 As shown, the atomizing assembly 2 includes an atomizing support 206 and an atomizing core 205. The atomizing core 205 is disposed on the atomizing support 206, and a liquid-absorbing component 5 is assembled inside the atomizing support 206, corresponding to the atomizing core 205. The liquid-absorbing component 5 can absorb liquid flowing out of the atomizing assembly 2, such as atomizing matrix or condensate, which helps to further improve leakage problems. In this embodiment, the liquid-absorbing component 5 can be, but is not limited to, a liquid-retaining cotton.

[0065] In some embodiments, the atomizing support 206 includes a first support 2061 and a second support 2062. The first support 2061 is connected to the drive assembly 8, and the second support 2062 is connected to the atomizing assembly 2. The first support 2061 and the second support 2062 are fixedly connected to form a liquid collection space 2063. The liquid suction member 5 is disposed within the liquid collection space 2063. The atomizing assembly 2 has an air inlet 202 at one end near the drive assembly 8. The air inlet 202 is located at the lower end of the atomizing core 205. The liquid suction member 5 corresponds to the air inlet 202 and is used to absorb the atomizing matrix or condensate leaking through the air inlet 202. The first support 2061 and the second support 2062 are connected to form the liquid collection space 2063, which facilitates the assembly of the liquid suction member 5. This embodiment does not limit the specific structure of the liquid collection space 2063; any structure that can accommodate the liquid suction member 5 is acceptable. The air inlet 202 of the atomizing component 2 may be, but is not limited to, a perforated structure.

[0066] In some implementations, such as Figure 2 , Figure 3 As shown, the atomizing device also includes an air guide tube 10. The housing assembly 1 is provided with a vent hole 104, a guide structure 107, and an air guide structure 108. One end of the air guide tube 10 is fixed to the atomizing support 206, and the air guide tube 10 is in gas communication with the atomizing core 205. The air guide tube 10 moves with the atomizing assembly 2. The other end of the air guide tube 10 is movably engaged with the guide structure 107. The guide structure 107 forms a second guide hole 103, and the air guide structure 108 forms an air guide cavity 109. The air guide tube 10 passes through the second guide hole 103 and communicates with the air guide cavity 109. The air guide cavity 109 connects the vent hole 104 and the air guide tube 10. In this embodiment, the air guide tube 10 passes through the second guide hole 103 and can movably engage with the second guide hole 103. The guide structure 107 guides the movement of the air guide tube 10, which helps to improve the stability of the movement. In some embodiments, the upper end of the air guide tube 10 can be connected to the liquid collection space 2063, thereby communicating with the gas in the atomizing core 205. The lower end of the air guide tube 10 is connected to the vent 104 through the air guide cavity 109, thereby allowing external gas to enter the atomizing assembly 2 through the vent 104, the air guide cavity 109, the air guide tube 10, and the liquid collection space.

[0067] In one embodiment, a protruding boss is provided on the inner side of the bottom 106 of the housing assembly 1. This boss is the guide structure 107, and a second guide hole 103 is provided on the boss. In another embodiment, the air guiding structure 108 may be a cavity or hole structure integrally formed on the bottom 106 of the housing assembly 1, or it may be a component with a cavity or hole structure assembled on the bottom 106 of the housing assembly 1. In this embodiment, the air guiding structure 108 is located between the second guide hole 103 and the vent hole 104, and the vent hole 104 communicates with the outside.

[0068] In one embodiment, such as Figure 2 , Figure 3 As shown, the atomizing device also includes a first sealing element 3, which is disposed at the bottom of the liquid storage chamber 101 to seal the liquid storage chamber 101. The first sealing element 3 has an assembly hole 301. The atomizing assembly 2 includes an atomizing tube 203, and a liquid inlet 201 is disposed on the atomizing tube 203. The atomizing tube 203 is movably inserted into the assembly hole 301 to isolate or connect the liquid inlet 201 with the liquid storage chamber 101. When the atomizing assembly 2 is in the second position, the liquid inlet 201 on the atomizing tube 203 protrudes from the assembly hole 301 into the liquid storage chamber 101, thereby connecting the liquid storage chamber 101 with the liquid inlet 201. At this time, the atomizing matrix in the liquid storage chamber 101 can enter the atomizing tube 203 from the liquid inlet 201 and be absorbed by the liquid storage element 204 inside the atomizing tube 203. When the atomizing component 2 is switched from the second position to the first position, the liquid inlet 201 on the atomizing tube 203 is sealed by the first seal 3 within the assembly hole 301. The atomizing matrix in the storage chamber 101 cannot enter the atomizing tube 203 through the liquid inlet 201, thus preventing excessive atomizing matrix from entering the storage component 204 and causing leakage. In this embodiment, the first seal 3 can be, but is not limited to, silicone sealant. In one embodiment, the lower end of the atomizing tube 203 can be fixedly connected to the second support 2062, thereby connecting the atomizing support 206 to the atomizing component 2.

[0069] In one embodiment, such as Figure 2 , Figure 3 As shown, the atomizing assembly 2 also includes a liquid storage component 204 disposed within the atomizing tube 203, and an atomizing core 205 also disposed within the atomizing tube 203. The liquid storage component 204 surrounds the outer periphery of the atomizing core 205, and is used to absorb the atomizing matrix and provide the atomizing matrix to the atomizing core 205. Because the liquid storage component 204 surrounds the outer periphery of the atomizing core 205, the atomizing matrix in the liquid storage component 204 can enter the atomizing core 205 and be heated, thereby forming an aerosol. In this embodiment, the liquid storage component 204 can be, but is not limited to, a liquid storage cotton. The atomizing core 205 in this application can be a ceramic core; or it can be a heating assembly, which includes a support, a liquid storage cotton disposed within the support, and a heating wire for heating the atomizing matrix in the liquid storage cotton.

[0070] In one embodiment, such as Figure 2 , Figure 3As shown, an assembly cavity 105 is provided inside the housing assembly 1 near the top of the liquid storage chamber 101. A second sealing element 11 is provided within the assembly cavity 105. The second sealing element 11 is fitted to the end of the atomizing tube 203 away from the assembly hole 301 and is movably disposed within the assembly cavity 105 together with the atomizing tube 203. The second sealing element 11 is used to prevent the atomizing matrix in the liquid storage chamber 101 from entering the atomizing tube 203. Both the upper and lower ends of the atomizing tube 203 are sealed, which helps prevent the atomizing matrix from directly entering the atomizing assembly 2 from the end of the atomizing tube 203, thus avoiding leakage of the atomizing matrix. In this embodiment, the second sealing element 11 is fixed to the upper end of the atomizing tube 203. When the atomizing assembly 2 is movable, both the end of the atomizing tube 203 and the second sealing element 11 slide within the assembly cavity 105, achieving both sealing of the end of the atomizing tube 203 and ensuring the mobility of the atomizing assembly 2. In some embodiments, when the housing assembly 1 is made of plastic, a cavity structure can be provided inside the housing assembly 1 near the top of the liquid storage chamber 101. A metal sleeve 12 can be fixedly installed in this cavity structure, and the second sealing member 11 and the end of the atomizing tube 203 are movably disposed within the metal sleeve 12. The structure of the metal sleeve 12 is stable, which is beneficial to the good sealing of the second sealing member 11. In this embodiment, the second sealing member 11 can be made of sealing silicone, and a portion of the second sealing member 11 can be inserted into the atomizing tube 203 to form a seal. To ensure the sealing effect and good mobility of the upper end of the atomizing tube 203, the second sealing member 11 can be fitted with the assembly cavity 105 with a transition or clearance fit, and a sealing ring is provided on the outer periphery of the second sealing member 11. The sealing ring is interference-fitted between the second sealing member 11 and the cavity wall of the assembly cavity 105. In some embodiments, a portion of the second sealing member 11 may be interference-fitted with the assembly cavity 105, while the remaining portion may be clearance-fitted or transition-fitted. In some application scenarios, because the atomizing component 2 is movable, an air outlet channel can be provided on the housing component 1 to facilitate the flow of aerosol. The end of the air outlet channel near the atomizing component 2 is inserted into the atomization channel of the atomizing component 2, and when the atomizing component 2 is in the first position, the air outlet channel is still located within the atomization channel. In this embodiment, the atomization channel is located within the atomizing tube 203.

[0071] In one embodiment, the driving body comprises any material selected from shape memory alloy and shape memory polymer. In some embodiments, the material of the driving body 801 may also include a two-way shape memory material. The driving body 801 presents and maintains a first shape when the temperature is below a first set temperature but above the low-temperature failure temperature, and presents and maintains a second shape when the temperature reaches or exceeds a second set temperature but is below the high-temperature failure temperature. Temperature control is used to achieve shape switching of the driving body 801, thus improving the deformation stability of the driving body 801. This embodiment does not limit the specific range of the first and second set temperatures; they can be set according to different materials and the required driving force.

[0072] In one embodiment, such as Figure 2 , Figure 3 As shown, the stabilizing elastic element 802 can be a compression spring, the memory elastic element can be a memory spring, and the transmission element 4 includes a rod-shaped guide portion 402. The memory spring is sleeved on the guide portion 402 and abuts against the force-receiving portion 401 and the spring support seat. The compression spring abuts against the force-receiving portion 401 and the support portion 601. The compression spring can apply a restoring force to the force-receiving portion 401, and the memory spring can apply a driving force to the force-receiving portion 401, thereby realizing the driving component 8 to drive the transmission element 4 and drive the atomizing component 2 to move. The memory spring sleeved on the rod-shaped guide portion 402 has a guiding and limiting function for the deformation of the memory spring, which is beneficial to improving the stability of the structure. In this embodiment, the rod-shaped guide portion 402 and the force-receiving portion 401 can be a single structure. The force-receiving portion 401 is located at the end of the guide portion 402 near the atomizing component 2, and the outer periphery of the force-receiving portion 401 protrudes from the outer periphery of the guide portion 402. In some embodiments, a guiding cylindrical structure can be provided on the side of the force-bearing part 401 away from the guide part 402, and one end of the compression spring is assembled in the cylindrical structure, which can also guide the deformation of the compression spring. If the support part 601 provided on the inner bracket 6 interferes with the transmission member 4, a corresponding clearance structure, such as a hole structure or a slot structure, can be provided on the support part 601 so that the transmission member 4 passes through the support part 601 and extends to the top of the support part 601 to connect with the first support 2061.

[0073] In one embodiment, the atomizing device includes a driving circuit. The two ends of the driving body 801 are electrically connected to the driving circuit. The driving circuit applies voltage to the two ends of the driving body 801, causing the temperature of the driving body 801 to rise and generate a deformation that increases its length, thus presenting and maintaining a second shape. The shape change of the driving body 801 is an increase or decrease in length, which is a change in length in a certain direction. The length direction of the driving body 801 can be consistent with the direction of movement of the atomizing component 2. When the driving body 801 extends from the first shape to the second shape, it can drive the atomizing component 2 to move upward from the first position to the second position, thereby connecting the liquid inlet 201 with the liquid storage chamber 101. In some embodiments, the driving circuit can be formed on a circuit board 9, meaning that the circuit board 9 can not only control the operation of the atomizing core 205 but also control the temperature change of the driving body 801.

[0074] In one embodiment, for ease of understanding, an example of the specific working process of the atomizing device of this application is as follows: The driving component 8 includes a compression spring and a memory spring respectively abutting against the upper and lower sides of the force-receiving part 401. When the circuit board 9 does not apply voltage to the two ends of the memory spring or applies a relatively small voltage to the two ends of the memory spring, the temperature of the memory spring is lower than the first set temperature, the memory spring is in the first state, and the atomizing component 2 is in the first position. When it is necessary to replenish the atomizing matrix, the circuit board 9 can apply voltage or a relatively large voltage to the two ends of the memory spring, causing the temperature of the memory spring to rise and exceed the second set temperature, the length of the memory spring to extend, switching from the first state to the second state, and driving the atomizing component 2 to move upward through the transmission component 4, switching from the first position to the second position, so that the liquid inlet 201 is exposed and connected to the liquid storage chamber 101. When it is necessary to stop the replenishment of the atomizing matrix, the circuit board 9 can be controlled to not apply voltage to the two ends of the memory spring or apply a relatively small voltage to the two ends of the memory spring, so that the temperature of the memory spring is lower than the first set temperature, the memory spring returns to the first form, and the atomizing component 2 is driven to switch from the second position to the first position through the transmission component 4. The liquid inlet 201 enters the assembly hole 301 of the first seal 3 and is sealed by the first seal 3. The liquid inlet 201 is isolated from the liquid storage chamber 101, which helps to improve the leakage problem.

[0075] The atomizing component 2 provided in the above embodiment is movably disposed on the housing component 1. Within the movement stroke of the atomizing component 2, the atomizing component 2 has a first position and a second position. In the first position, the liquid inlet 201 is isolated from the liquid storage chamber 101. In the second position, the liquid inlet 201 is connected to the liquid storage chamber 101. The driving component 8 includes a driving body 801, which has at least a first form and a second form. The driving body 801 switches between the first form and the second form in response to temperature. The atomizing component 2 switches between the first position and the second position in response to the form switching of the driving body 801. When the driving body 801 switches from the second form to the first form in response to temperature, the atomizing component 2 is in the first position in response to the form switching of the driving body 801. This prevents the atomizing matrix from entering the atomizing component 2, which helps to improve the leakage problem and enhance the user experience.

[0076] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
