[0043] This application provides an aerosol generating device, which includes a power supply component and an atomizer according to any embodiment of this application.

In this application embodiment, the aerosol generating matrix can be a liquid material made primarily of plants (such as tobacco) with added aerosol forming agents and aroma materials.

[0044] The power supply unit is electrically connected to the atomizer. The power supply unit is mainly used to supply power to the atomizer and control the opening and closing of the entire aerosol generation device.

[0045] Those skilled in the art will understand that the embodiments of this application do not specifically limit the type of aerosol generating device. For example, an aerosol generating device may be a medical nebulizer, an air humidifier, or an electronic cigarette, etc., that requires the use of a nebulizer.

[0046] This application provides an atomizer 10 in an embodiment. Please refer to [link / reference]. Figures 1 to 9The atomizer 10 includes an oil reservoir 1 and an atomizing assembly 2. The oil reservoir 1 includes a housing assembly 11, a base assembly 12, and a first liquid inlet channel 15. A liquid storage chamber 13 is defined between the base assembly 12 and the housing assembly 11, and the liquid storage chamber 13 is used to store the aerosol generation matrix. At least a portion of the base assembly 12 is movable relative to the housing assembly 11 in a first direction. During the assembly of the atomizing assembly 2 and the oil reservoir 1, the oil reservoir 1 is in fluid communication with the atomizing assembly 2 through the first liquid inlet channel 15, and the atomizing assembly 2 enables the base assembly 12 to move relative to the housing assembly 11 in the first direction.

[0047] The atomizer 10 is a device that converts liquid into tiny droplets. It is widely used in electronic cigarettes, medical spray equipment, aromatherapy machines and other fields. Through a specific working mechanism, it allows the liquid to be dispersed in a mist form, making it easy for users to inhale and diffuse, and meeting the needs of different scenarios.

[0048] The oil storage tank 1 is a component in the atomizer 10 used to store the liquid to be atomized (i.e., the aerosol generation matrix), continuously providing liquid raw materials for the atomization process and ensuring uninterrupted atomization operation. The oil storage tank 1 can hold a sufficient amount of liquid to ensure that the atomizer 10 operates stably for a period of time.

[0049] The shell assembly 11 forms part of the external frame structure of the oil storage tank 1, serving to protect the internal structure, house other components, and define the internal functional space. It provides overall mechanical strength to the oil storage tank 1 and reduces damage to internal delicate components caused by external forces. In addition, the shell assembly 11 can shape and contour the oil storage tank 1 to meet consumers' aesthetic requirements.

[0050] The base assembly 12 is located at the bottom of the oil storage tank 1 and together with the shell assembly 11, constitutes the oil storage tank 1. The base assembly 12 can define the liquid storage cavity 13 together with the shell assembly 11, and also has functions such as connecting with other components and conducting liquid.

[0051] The first liquid inlet channel 15 is a channel structure installed on the oil storage tank 1. Its main function is to serve as a passage for liquid flow, so that the aerosol generating matrix in the liquid storage chamber 13 can be smoothly transported to the aerosol generating matrix of the atomizing component 2.

[0052] The specific structure of the first liquid inlet channel 15 is not limited here. The first liquid inlet channel 15 is generally a tubular structure, and the diameter of the tube will be designed according to factors such as the atomization efficiency and liquid storage capacity of the atomizer 10.

[0053] For example, the inner wall of the first liquid inlet channel 15 can be made of smooth stainless steel, which is not only corrosion resistant, but also reduces liquid flow resistance and reduces liquid residue.

[0054] In some embodiments, the first liquid inlet channel 15 can be designed as a spiral to increase the flow path of the liquid in the channel, so that the liquid is more evenly dispersed when it enters the liquid storage chamber 13, avoiding local impact that causes liquid splashing, bubble generation, etc., which would affect the subsequent atomization effect.

[0055] For example, a one-way valve structure can be provided at one end of the first liquid inlet channel 15 near the liquid storage chamber 13, which only allows liquid to flow towards the liquid storage chamber 13, preventing the liquid in the liquid storage chamber 13 from flowing back to the outside under some special circumstances (such as the atomizer 10 tilting or shaking), ensuring the stability of the liquid level in the liquid storage chamber 13 and the purity of the liquid, and preventing external impurities from re-entering the liquid storage chamber 13 with the backflowing liquid.

[0056] The first receiving cavity 121 is a space enclosed inside the housing assembly 11, and the first receiving cavity 121 provides a place for the base assembly 12 and other related components.

[0057] The liquid storage chamber 13 is a cavity specifically designed to store the liquid to be atomized. It is formed by the cooperation of the base assembly 12 and the housing assembly 11 to ensure stable liquid storage, prevent leakage, and stably deliver liquid to the atomizing assembly 2 as needed.

[0058] The volume of the liquid storage chamber 13 is determined according to actual needs and is not limited here. It can be understood that the volume of the liquid storage chamber 13 is determined by the size of the first receiving chamber 121 and the setting position of the base assembly 12.

[0059] The base assembly 12 and the housing assembly 11 cooperate with each other, and their outlines and shapes fit together to define the liquid storage cavity 13. At the same time, the base assembly 12 has the ability to move relative to the housing assembly 11 in a first direction, thereby changing the volume of the liquid storage cavity 13 and thus changing the pressure inside the liquid storage cavity 13.

[0060] For example, at least a portion of the base assembly 12 can move relative to the housing assembly 11 along a first direction. This can be achieved by nesting a portion of the base assembly 12 into the first receiving cavity 121 and sliding it, or by nesting a portion of the housing assembly 11 into the base assembly 12 and sliding it. The specific connection method of the relative movement between the base assembly 12 and the housing assembly 12 is determined according to actual needs.

[0061] In some embodiments, a slide rail or groove is provided on the inner wall and / or outer wall of the housing assembly 11 along the first direction. Correspondingly, the edge of the base assembly 12 is equipped with a slider and a protrusion. The two fit together precisely to achieve smooth and accurate linear sliding of the base assembly 12, avoiding deviation or jamming during movement, and ensuring the accuracy of docking between the liquid storage chamber 13 and the atomizing assembly 2 after each displacement.

[0062] For example, elastic limit blocks can also be added to both ends of the slide rail to limit the movement range of the base assembly 12 and prevent excessive displacement from causing structural damage or liquid leakage.

[0063] For example, a conventional rubber sealing ring can be provided around the edge of the liquid reservoir 13 on the contact surface between the housing assembly 11 and the base assembly 12. A multi-layer sealing design can also be used, such as adding a soft silicone sealing gasket, which can adaptively deform to fill tiny gaps during the movement of the base assembly 12.

[0064] In some cases, sealing grease can be applied to frequently moving joints to reduce the coefficient of friction, which not only helps with smooth movement but also further prevents liquid leakage.

[0065] In some embodiments, a cleverly designed linkage structure is employed. When the base assembly 12 moves along the first direction until the liquid storage chamber 13 is fully connected to the atomizing assembly 2, a micro switch is activated. The switch signal is transmitted to the main control board of the atomizer 10, illuminating the indicator light to indicate to the user that the device is properly assembled. In other embodiments, when the atomizing coil 23 is fully filled with liquid, the indicator light can also indicate to the user that the device is ready to operate. Conversely, when the device moves back to its initial position and disconnects, the same feedback signal is sent, allowing the main control board to pause some circuit power consumption and enter a standby power-saving mode.

[0066] For example, the atomizing component 2 can be nested into the oil storage tank 1, or the oil storage tank 1 can be nested into the atomizing component 2. The specific connection method between the atomizing component 2 and the oil storage tank 1 is determined according to actual needs.

[0067] For example, the oil storage tank 1 and the atomizing component 2 are connected non-detachably after one assembly, which ensures the reliability of the connection between the oil storage tank 1 and the atomizing component 2 and helps to reduce the risk of oil leakage.

[0068] In some embodiments, the oil reservoir 1 and the atomizing component 2 are detachably connected. The specific structure of the detachable connection is not limited here. Exemplarily, small, powerful magnets are embedded on the corresponding contact surfaces of the atomizing component 2 and the oil reservoir 1, with their magnetic poles precisely matched. When the two come close, they automatically, quickly, and securely adhere to each other using magnetic attraction, achieving precise alignment and connection. Simultaneously, to prevent accidental detachment, a mechanical latch structure can be added as an auxiliary feature. The latch is designed to unlock with a light press, facilitating user disassembly.

[0069] For example, the atomizing component 2 and the oil reservoir 1 are designed with unique plug-in interfaces, with multiple spring clips installed inside the interfaces. When the atomizing component 2 is inserted into the interface of the oil reservoir 1, the spring clips are compressed and deformed, tightly clamping the inserted component and providing a stable connection force. In some embodiments, a flexible silicone sealing ring is wrapped around the outside of the interface to ensure a tight seal during connection and prevent liquid leakage.

[0070] This application does not specifically limit the first direction, and it can be any direction. For ease of explanation, the first direction in the embodiments of this application is the direction shown in the accompanying drawings, that is, the first direction of the atomizer 10.

[0071] The atomizing component 2 is the core part of the atomizer 10. Its structure typically includes an atomizing core 23, electrodes, etc. The atomizing core 23 is the key part that directly acts on the liquid to atomize it. It is responsible for converting the liquid delivered from the oil reservoir 1 into mist particles, using technologies such as ultrasonic vibration and heating wire evaporation to achieve the atomization goal. The atomizing component 2 determines the atomization effect and quality. The electrodes are used to connect to the power supply component to obtain electrical energy, and their performance and quality directly determine the atomization effect and quality.

[0072] The specific structure of the fluid connection between the liquid storage chamber 13 and the atomizing component 2 is not limited here. After the atomizing component 2 is plugged in and assembled, the liquid storage chamber 13 and the atomizing component 2 are fluidly connected, and the aerosol generation matrix can be delivered to the atomizing core 23, so that the atomizer 10 can work normally.

[0073] To meet market demands or regulatory requirements, the structure of the atomizer 10 used to store the aerosol generation matrix and other structures of the atomizer 10 need to be designed as detachable. This means that upon initial use, after assembling the atomizer 10, a waiting period is required for the aerosol generation matrix to be delivered to the atomizing core 23 before normal use. If the waiting time is too short, the aerosol generation matrix may not have reached the atomizing core 23, easily causing the atomizing core 23 to burn dry, resulting in a burnt smell and affecting the user experience.

[0074] During the assembly of the atomizing component 2 and the oil storage tank 1, the oil storage tank 1 can be fluidly connected to the atomizing component 2 through the first liquid inlet channel 15. Here, it can be a partial connection between the first liquid inlet channel 15 and the atomizing component 2. Thus, when the atomizing component 2 further allows the base component 12 to move relative to the shell component 11 along a first direction, the base component 12 can drive the shell component 11 to move along the first direction, reducing the volume of the oil storage tank 1 and increasing the internal pressure. The aerosol generation matrix within the oil storage tank 1 can then flow through the first liquid inlet channel 15 to the atomizing core 2 of the atomizing component. When the atomizing component 2 is fully assembled, the first liquid inlet channel 15 and the atomizing component 2 are completely fluidly connected, achieving optimal connectivity.

[0075] The atomizer 10 provided in this embodiment defines a liquid storage chamber 13 by a base assembly 12 and a housing assembly 11. The liquid storage chamber 13 is used to store the aerosol generation matrix. By configuring the base assembly 12 to be at least movable relative to the housing assembly 11 in a first direction, during assembly, the oil reservoir 1 can be fluidly connected to the atomizing component 2 through the first liquid inlet channel 15. The atomizing component 2 drives the base assembly 12 to move, thereby reducing the volume of the liquid storage chamber 13 and increasing the pressure inside the liquid storage chamber 13. This causes the aerosol generation matrix to be squeezed out of the liquid storage chamber 13 under pressure, accelerating the delivery of the aerosol generation matrix to the atomizing core 23 and shortening the user's waiting time. At the same time, at least a portion of the atomizing component 2 is inserted into the insertion channel 14 and can drive the base assembly 12 to move relative to the housing assembly 11 in the first direction. The squeezing of the aerosol generation matrix occurs simultaneously with the assembly of the atomizer 10, requiring no additional operation, simplifying the operation process and further improving the user experience.

[0076] In some embodiments, please refer to Figures 1 to 9 The base assembly 12 includes a base 122 and a valve assembly 16. The base 122 is provided with a insertion channel 14 and a first liquid inlet channel 15. The valve assembly 16 is capable of sealing the first liquid inlet channel 15. At least a portion of the atomizing assembly 2 can be inserted into the insertion channel 14, causing the valve assembly 16 to move, so that the oil storage tank 1 is in fluid communication with the atomizing assembly 2 through the first liquid inlet channel 15.

[0077] The base 122, as the main structure of the base assembly 12, fits closely and works in coordination with the shell assembly 11. The base 122 defines key structures such as the insertion channel 14 and the first liquid inlet channel 15, providing a basic platform for the integration of various components and effectively ensuring a reasonable and stable internal structural layout.

[0078] The insertion channel 14 is a channel structure reserved inside the base assembly 12 for the insertion of other components. The insertion channel 14 can guide and position the inserted components and establish liquid or electrical connections, ensuring that the connected components are accurately connected and work together.

[0079] For example, the atomizing component 2 can cooperate with the base component 12 in the insertion channel 14. After the cooperation is completed, one end of the first liquid inlet channel 15 is connected to the atomizing component 2, so as to realize the liquid flow communication between the first liquid inlet channel 15 and the atomizing component 2.

[0080] In some embodiments, conductive contacts are provided on the contact surfaces of the insertion channel 14 and the atomizing component 2. The insertion channel 14 and the atomizing component 2 cooperate to achieve electrical connection by contacting the conductive contacts of the insertion channel 14 and the atomizing component 2.

[0081] The valve assembly 16 is a key part of the base assembly 12. The valve assembly 16 can be partially disposed in the insertion channel 14. When the atomizing component 2 is inserted into the insertion channel 14, the valve assembly 16 can also contact the atomizing component 2. The movement of the atomizing component 2 drives the movement of the valve assembly 16, thereby realizing the function of sealing or opening the first liquid inlet channel 15.

[0082] Here, the valve assembly 16 being able to seal the first liquid inlet channel 15 means that the valve assembly 16 can both seal the first liquid inlet channel 15 and open the first liquid inlet channel 15.

[0083] The valve assembly 16 sealing the first liquid inlet channel 15 means that there is an overlapping area between the valve assembly 16 and the first liquid inlet channel 15. This overlapping area can completely seal the first liquid inlet channel 15, preventing the aerosol generating matrix from moving within the first liquid inlet channel 15. For example, the valve assembly 16 may have a portion of its structure that can extend into the first liquid inlet channel 15, or the valve assembly 16 may have a portion of its structure located at the port of the first liquid inlet channel 15. When the aerosol generating matrix moves to the valve assembly 16, it is blocked by the valve assembly 16 and cannot continue to move, thereby achieving the interception function of the valve assembly 16 on the first liquid inlet channel 15.

[0084] When the valve assembly 16 moves away from the first liquid inlet channel 15, the overlapping area between the valve assembly 16 and the first liquid inlet channel 15 cannot completely seal the first liquid inlet channel 15, or there is no overlapping area between the valve assembly 16 and the first liquid inlet channel 15, the aerosol generating matrix can pass through the gap between the valve assembly 16 and the first liquid inlet channel 15 and continue to move within the first liquid inlet channel 15, thereby realizing the function of the valve assembly 16 opening the first liquid inlet channel 15.

[0085] The oil storage tank 1 is equipped with a first liquid inlet channel 15 and a valve assembly 16. The first liquid inlet channel 15 serves as a bridge for liquid flow between the liquid storage chamber 13 and the atomizing component 2, allowing liquid to enter and exit the liquid storage chamber 13 at appropriate times. The valve assembly 16 can selectively open or close the first liquid inlet channel 15 according to actual needs, thereby precisely controlling the liquid flow. When the atomizing component 2 is inserted into the insertion channel 14 of the base assembly 12 of the oil storage tank 1, a corresponding linkage is generated, causing the valve assembly 16 to open the first liquid inlet channel 15, enabling fluid communication between the liquid storage chamber 13 and the atomizing component 2, thus preparing the liquid delivery path for the subsequent atomization process. This allows the liquid storage chamber 13 to be closed when the atomizer 10 is disassembled and not in use to prevent leakage; and the liquid storage chamber 13 to be opened for liquid supply when the atomizer 10 is assembled and in use.

[0086] In some embodiments, please refer to Figures 1 to 6 At least a portion of the valve assembly 16 is movably disposed within the insertion channel 14. The first liquid inlet channel 15 penetrates the side wall of the insertion channel 14.

[0087] Here, the first liquid inlet channel 15 is a through-type transverse insertion channel 14. The atomizing component 2 is inserted into the insertion channel 14, causing the valve component 16 to move within the insertion channel 14. This layout allows the liquid transport path to intersect with the insertion path of the atomizing component 2. At the same time, the valve component 16 is movably placed within the insertion channel 14. Thus, when the atomizing component 2 is inserted into the insertion channel 14, the mechanical force generated by the insertion action or other pre-set linkage mechanisms can trigger the valve component 16 to move, thereby precisely opening the first liquid inlet channel 15, opening the liquid transport channel between the liquid storage chamber 13 and the atomizing component 2, improving the accuracy of the atomization process control, increasing the efficiency of the atomizer 10, reducing the difficulty of user operation, and thus improving the user experience.

[0088] In some embodiments, please refer to Figure 8 and Figure 9 At least a portion of the valve assembly 16 is movably disposed within the insertion channel 14. The first liquid inlet channel 15 extends through the base 122 along a first direction.

[0089] Here, the first liquid inlet channel 15 penetrates the base 122 directly along a predetermined first direction. When the atomizing component 2 is inserted into the first liquid inlet channel 15, it will cause the valve component 16 to move within the first liquid inlet channel 15. This layout allows the liquid transport route to cleverly intersect with the insertion path of the atomizing component 2. At the same time, the valve component 16 is flexibly positioned within the first liquid inlet channel 15. In this way, when the atomizing component 2 is inserted, the mechanical force generated by the insertion action or other pre-set linkage mechanisms can precisely trigger the valve component 16 to move, thereby precisely opening the first liquid inlet channel 15, opening the liquid transport channel between the liquid storage chamber 13 and the atomizing component 2, improving the accuracy of the atomization process control, increasing the efficiency of the atomizer 10, reducing the difficulty of user operation, and thus improving the user experience.

[0090] It should be noted that in the embodiment where the first liquid inlet channel 15 penetrates the base 122 along the first direction, please refer to [reference needed]. Figure 9 The first liquid inlet channel 15 serves as both a liquid inlet channel, performing the function of liquid inlet, and a part of the insertion channel 14, accommodating the atomizing component 2. The atomizing component 2 can be inserted into the insertion channel 14 (i.e., the first liquid inlet channel 15), and at least a portion of the valve assembly 16 is movably disposed in the insertion channel 14 (i.e., the first liquid inlet channel 15). The atomizing component 2 drives the valve assembly 16 to move within the insertion channel 14 (i.e., the first liquid inlet channel 15).

[0091] In some embodiments, the first liquid inlet channel 15 may be entirely disposed on the base 122. In other embodiments, the first liquid inlet channel 15 is partially disposed on the base 122 and partially disposed on the atomizing component 2. After the atomizer 10 is assembled, the base 122 and the atomizing component 2 come into contact and together define the first liquid inlet channel 15.

[0092] In some embodiments, please refer to Figures 1 to 6 The valve assembly 16 includes a first valve body 161, the circumferential sidewall of the first valve body 161 is slidably engaged with the sidewall of the insertion channel 14, and at least a portion of the atomizing assembly 2 is inserted into the interior of the first valve body 161.

[0093] The first valve body 161 is a structural component within the valve assembly 16. The first valve body 161 is responsible for controlling the liquid or gas passage and coordinating the operation of other components. Here, the first valve body 161 is a portion of the aforementioned valve assembly 16 that can extend into the first liquid inlet channel 15, or a portion of the valve assembly 16 may be located at the port of the first liquid inlet channel 15.

[0094] For example, the first valve body 161 is sleeve-shaped, that is, its shape is similar to a hollow cylinder, and it has a specific tubular structure. The sleeve-shaped structure facilitates the nesting of the first valve body 161 and the insertion channel 14 to form a sliding fit relationship. At the same time, it also facilitates the first valve body 161 to accommodate and guide the insertion of the atomizing component 2, thereby driving the movement of the first valve body 161.

[0095] The circumferential sidewall refers to the portion of the outer wall surrounding the first valve body 161. This part of the sidewall directly participates in the mechanical engagement with the insertion channel 14 and is a key contact surface for achieving functions such as relative movement and sealing. The sidewall typically has specific machining precision requirements to ensure a good fit with the associated components.

[0096] Here, since the first liquid inlet channel 15 penetrates the side wall of the insertion channel 14, the circumferential side wall of the first valve body 161 can open and close the first liquid inlet channel 15 during the sliding engagement with the side wall of the insertion channel 14. Specifically, since the first liquid inlet channel 15 penetrates the side wall of the insertion channel 14, that is, the first liquid inlet channel 15 has a port on the side wall of the insertion channel 14, the circumferential side wall of the first valve body 161 can block or avoid this port during the sliding engagement with the side wall of the insertion channel 14. When the circumferential side wall of the first valve body 161 blocks this port, the aerosol generating matrix is ​​blocked by the circumferential side wall of the first valve body 161 and cannot flow. When the circumferential sidewall of the first valve body 161 avoids this port, the aerosol generating matrix can flow out from this port. Since the atomizing core 23 of the atomizing component 2 can extend into the insertion channel 14, the aerosol generating matrix can contact the atomizing core 23 in the insertion channel 14, thereby achieving fluid communication between the atomizing component 2 and the first liquid inlet channel 15.

[0097] The specific material of the first valve body 161 is not limited here. For example, the first valve body 161 is often made of materials that are wear-resistant, corrosion-resistant and have high mechanical strength, such as stainless steel and engineering plastics, to ensure long-term stable operation.

[0098] In some embodiments, multiple parallel guide rail grooves are added axially along the sidewall of the insertion channel 14, and a protruding slider is provided at the corresponding position on the circumferential sidewall of the first valve body 161. The slider is precisely embedded in the groove, making the sliding engagement more accurate and completely eliminating the risk of valve body rotation or tilting. An elastic buffer block is provided at the end of the guide rail groove. When the valve body slides to the limit position, the buffer block absorbs the impact force and prevents hard collisions from damaging the components.

[0099] For example, the first valve body 161 is designed in a sleeve shape and is disposed within the insertion channel 14. It achieves flexible movement through a sliding fit between its circumferential sidewall and the sidewall of the insertion channel 14. Simultaneously, at least a portion of the atomizing component 2 is inserted into the first valve body 161. This arrangement allows the insertion of the atomizing component 2 to be synchronized with the movement of the first valve body 161. The movement of the atomizing component 2 can drive the movement of the first valve body 161, thereby precisely controlling the opening and closing of the first liquid inlet channel 15.

[0100] In some embodiments, a connection structure, such as a snap-fit ​​structure, is provided at the contact position between the first valve body 161 and the atomizing component 2. After at least a portion of the atomizing component 2 is inserted into the first valve body 161, the first valve body 161 is connected to the atomizing component 2. The atomizing component 2 pushes the first valve body 161 away from its initial position, and the first valve body 161 avoids the port of the first liquid inlet channel 15 on the side wall of the insertion channel 14, thereby achieving fluid communication between the atomizing component 2 and the first liquid inlet channel 15.

[0101] When the atomizing component 2 is pulled out, the first valve body 161 moves to the initial position along with the atomizing component 2 under the drive of the connecting structure. The first valve body 161 blocks and avoids the port of the first liquid inlet channel 15 on the side wall of the insertion channel 14, thereby achieving a seal.

[0102] In some embodiments, a blocking structure is provided on the insertion channel 14. The blocking structure restricts the atomizing component 2 from moving the first valve body 161 away from the initial position after it is pulled out.

[0103] In some embodiments, the connection structure between the atomizing component 2 and the first valve body 161 can be disconnected when the resistance provided by the blocking structure is sufficiently large.

[0104] In some embodiments, please refer to Figures 4 to 6 The valve assembly 16 includes a first elastic element 162, one end of which abuts against the housing assembly 11 or the base 122, and the other end abuts against the first valve body 161. When the atomizing assembly 2 is inserted into the insertion channel 14, it causes the first valve body 161 to open the first liquid inlet channel 15, and the first elastic element 162 undergoes elastic deformation.

[0105] The first elastic element 162 is a key component in the valve assembly 16. It has the ability to deform elastically and can change its shape under the action of external force. When the external force disappears, it can return to its initial shape. This characteristic is used in the structure to provide elastic force, realize reset and assist the movement of components.

[0106] The specific type of the first elastic element 162 is not limited here; for example, it can be a spring, a sheet, etc.

[0107] For example, if a spring is selected as the first elastic element 162, the spring can be designed as a variable diameter structure. The diameter of the part that contacts the housing assembly 11 or the base 122 and the first valve body 161 at both ends can be appropriately increased. This can increase the contact area, make the force more uniform, and reduce wear caused by excessive local pressure.

[0108] For example, some small buffer rubber strips can be set between the coils of the spring. When the spring is compressed or stretched, the rubber strips can play a buffering role, further reducing vibration and noise, and also helping to improve the overall stability of the spring.

[0109] For example, a concave mounting groove can be designed at the contact point between the housing assembly 11 or the base 122 and the first elastic member 162. The inner wall of the mounting groove is inlaid with a wear-resistant nylon gasket, and one end of the first elastic member 162 is embedded in the mounting groove and tightly fitted with the nylon gasket. In this way, reliable positioning can be ensured, and the coefficient of friction between the two during relative movement (such as when the elastic member extends or retracts) can be reduced, thereby reducing wear.

[0110] For example, a guide post is provided at the corresponding position where the first valve body 161 is connected to the first elastic member 162. The guide post passes through the central hole of the first elastic member 162, and its outer diameter is fitted with the inner diameter of the central hole of the elastic member with a small clearance, so that the first elastic member 162 moves precisely along the direction of the guide post during the extension and retraction process, avoiding skewing, twisting and other situations. At the same time, a limiting protrusion is provided at the end of the guide post to prevent the first elastic member 162 from coming off the guide post when subjected to excessive force.

[0111] One end of the first elastic element 162 in the valve assembly 16 abuts against the housing assembly 11 or the base 122, while the other end abuts against the first valve body 161, forming a mechanical connection structure. When the atomizing assembly 2 is inserted into the insertion channel 14, the pushing force on the atomizing assembly 2 is transmitted to the first valve body 161 in contact with the atomizing assembly 2. The first valve body 161 moves, overcoming the elastic force of the first elastic element 162, and simultaneously opens the first liquid inlet channel 15, allowing the liquid to flow to the atomizing assembly 2 for atomization. During this process, the first elastic element 162 undergoes corresponding elastic deformation.

[0112] At the same time, the atomizing component 2 pushes the first valve body 161 away from the initial position, and the first valve body 161 avoids the port of the first liquid inlet channel 15 on the side wall of the insertion channel 14, so as to realize the fluid communication between the atomizing component 2 and the first liquid inlet channel 15.

[0113] In some embodiments, the atomizing component 2 disengages from the insertion channel 14, the first elastic element 162 recovers its elastic deformation, the first valve body 161 moves under the elastic force of the first elastic element 162, and seals the first liquid inlet channel 15.

[0114] Here, the atomizing component 2 is a detachable structure. When the atomizing component 2 is pulled out from the insertion channel 14, the external force applied to the first valve body 161 disappears. The first elastic element 162, by virtue of its own elastic deformation recovery property, generates an elastic force to push the first valve body 161 back to its initial position. The first valve body 161 blocks and avoids the port of the first liquid inlet channel 15 on the side wall of the insertion channel 14, sealing the first liquid inlet channel 15 and preventing the liquid from continuing to flow. In this way, automatic sealing control of the liquid passage based on the insertion and removal action of the atomizing component 2 is realized.

[0115] The first elastic element 162 is provided so that after the atomizing component 2 is dislodged, the first valve body 161 can be reliably reset and the first liquid inlet channel 15 can be sealed. This effectively prevents the liquid in the storage chamber 13 from leaking in a non-atomizing state, maintains the amount and purity of the internal liquid, avoids damage to other components or affect the atomization effect due to leakage, and improves the overall reliability and stability of the atomizer 10.

[0116] In some embodiments, please refer to Figures 7 to 9 The valve assembly 16 includes a sealing part 163 and a second elastic member 164. One end of the second elastic member 164 abuts against the housing assembly 11 or the base 122, and the other end abuts against the sealing part 163. When the atomizing assembly 2 is inserted into the first liquid inlet channel 15, it causes the sealing part 163 to open the first liquid inlet channel 15, and the second elastic member 164 undergoes elastic deformation.

[0117] The sealing part 163 is the part of the valve assembly 16 used to achieve the sealing function. The sealing part 163 can be in close contact with the first liquid inlet channel 15 to block the passage of liquid when it is not needed, prevent leakage, and ensure good sealing of the internal system of the atomizer 10. Here, the sealing part 163 is a part of the valve assembly 16 that can extend into the first liquid inlet channel 15, or a part of the valve assembly 16 is provided at the port of the first liquid inlet channel 15.

[0118] The specific structure of the sealing part 163 is not limited here. For example, it can be a rubber stopper, a silicone gasket, or a specially shaped part with a contact surface.

[0119] The second elastic element 164 is a key component in the valve assembly 16. It has the ability to deform elastically and can change its shape under the action of external force. When the external force disappears, it can return to its initial shape. This characteristic is used in the structure to provide elastic force, realize reset and assist the movement of components.

[0120] The specific type of the second elastic element 164 is not limited here; for example, it can be a spring, a sheet, etc.

[0121] In the valve assembly 16, the two ends of the second elastic element 164 abut against the housing assembly 11 or the base 122 and the sealing part 163, respectively, forming a mechanical connection structure. When the atomizing assembly 2 is inserted into the first liquid inlet channel 15, a certain mechanical force is generated. This force is transmitted to the sealing part 163, causing it to overcome the elastic force of the second elastic element 164 and move, thereby opening the first liquid inlet channel 15 and allowing the liquid to flow to the atomizing assembly 2 for atomization. During this process, the second elastic element 164 undergoes corresponding elastic deformation.

[0122] At the same time, the atomizing component 2 pushes the sealing part 163 away from the initial position, and the sealing part 163 avoids the first liquid inlet channel 15, so as to realize the fluid communication between the atomizing component 2 and the first liquid inlet channel 15.

[0123] In some embodiments, the atomizing component 2 disengages from the first liquid inlet channel 15, the second elastic member 164 recovers its elastic deformation, and the sealing part 163 moves under the elastic force of the second elastic member 164 and seals the first liquid inlet channel 15.

[0124] Here, the atomizing component 2 is a detachable structure. When the atomizing component 2 is pulled out from the first liquid inlet channel 15, the external force applied to the sealing part 163 disappears. The second elastic member 164, by virtue of its own elastic deformation recovery property, generates an elastic force to push the sealing part 163 back to its initial position. The sealing part 163 extends into the first liquid inlet channel 15 to block, thereby sealing the first liquid inlet channel 15 and preventing the liquid from continuing to flow. This achieves automatic sealing control of the opening and closing state of the first liquid inlet channel 15 based on the insertion and removal action of the atomizing component 2.

[0125] With the cooperation of the second elastic member 164, the sealing part 163 can ensure the sealing state of the first liquid inlet channel 15 after the atomizing component 2 is pulled out, effectively preventing the liquid in the liquid storage chamber 13 from leaking in the non-atomizing state, maintaining the amount and purity of the internal liquid, avoiding damage to other components or affecting the atomization effect due to leakage, and improving the overall reliability and stability of the atomizer 10.

[0126] In some embodiments, please refer to Figures 1 to 9 The housing assembly 11 and the atomizing assembly 2 together define the air outlet channel 3.

[0127] The exhaust channel 3 is a channel structure specifically designed to transport the aerosol formed after atomization. Its core function is to allow the aerosol to smoothly reach the area accessible to the user from the point of generation, ensuring that the tiny particles generated by atomization can be discharged in an orderly and efficient manner, creating favorable conditions for the user to inhale and diffuse the aerosol.

[0128] In some embodiments, the housing assembly 11 is provided with an air outlet communicating with the insertion channel 14, and the atomizing assembly 2 is provided with a first air outlet sub-channel. When the atomizing assembly 2 is inserted into the insertion channel 14, the air outlet communicates with the first air outlet sub-channel, and the air outlet and the first air outlet sub-channel together define the air outlet channel 3 forming the atomizer 10.

[0129] In some embodiments, the atomizing component 2, the valve component 16, and the housing component 11 together define an air outlet channel 3.

[0130] For example, the housing assembly 11 is provided with an air outlet communicating with the insertion channel 14, and the valve assembly 16 has a second receiving cavity into which the atomizing assembly 2 can be inserted. The valve assembly 16 has a second air outlet sub-channel communicating with the second receiving cavity on the side near the air outlet. When the atomizing assembly 2 is inserted into the second receiving cavity, it sequentially connects the first air outlet sub-channel, the second air outlet sub-channel, and the air outlet, which together define the air outlet channel 33.

[0131] The housing assembly 11 and the atomizing assembly 2 work together. After the atomizer 10 is assembled, a specific space is reserved and defined between the two to form the air outlet channel 33. When the atomizing assembly 2 atomizes the liquid into fine aerosol particles, these particles flow outward along the air outlet channel 33 defined by the two components, precisely guiding them to the user's inhalation and usage position, ensuring that the atomization results can be effectively utilized.

[0132] In one implementation, please refer to Figures 1 to 9 The atomizing component 2 includes an atomizing base 21, a liquid storage component 22, and an atomizing core 23. The liquid storage component 22 is sandwiched between the atomizing base 21 and the atomizing core 23. The atomizing base 21 is provided with a second liquid inlet channel 211. The first liquid inlet channel 15 can be fluidly connected to the liquid storage component 22 through the second liquid inlet channel 211.

[0133] The atomizer base 21 is the basic support and structural connection component in the atomizer assembly 2, which plays a role in providing stable support for other parts.

[0134] The atomizer base 21 is typically made of hard, chemically stable materials, such as engineering plastics or aluminum alloys. The atomizer base 21 needs to withstand a certain pressure and resist internal liquid corrosion in order to maintain structural integrity and functional stability.

[0135] The liquid storage component 22 is the main component in the atomizer 10 used to store the liquid to be atomized. The liquid storage component 22 is in contact with the atomizing core 23 and can directly supply liquid to the atomizing core 23. By controlling the amount of aerosol generation matrix delivered to the atomizing core 23, the amount of aerosol generation can be controlled.

[0136] The specific material of the reservoir 22 is not limited here. The reservoir 22 includes any suitable material and combination of materials capable of transporting the liquid aerosol forming matrix toward the atomizer 10. The reservoir 22 should have capillary action, capable of adsorbing the aerosol forming matrix by capillary force. It can be a capillary material.

[0137] The specific type of capillary material is not limited here. For example, capillary materials may include sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, foamed metal or plastic materials, fibrous materials (e.g., made of virgin or pressed fibers (e.g., cellulose acetate fibers, polyester fibers, bonded polyolefin fibers, polyethylene fibers, polyester fibers or polypropylene fibers, nylon fibers)) or ceramics.

[0138] Capillary materials possess capillaries, and capillaries can have any suitable capillary action in order to be used with different liquid physical properties.

[0139] Capillary materials can include materials that are porous themselves, such as ceramic materials like alumina (corundum). Alternatively, porous materials can include materials with multiple fabricated pores to allow the liquid flotation matrix to migrate into the atomizing device. Porous materials can also include hydrophilic materials to improve the distribution and diffusion of the liquid flotation matrix.

[0140] Porous materials can have any suitable porosity in order to be used with different liquid physical properties.

[0141] The liquid reservoir 22 can also be made of other materials with capillary channels, such as plastic, stainless steel, glass, silicone, etc.

[0142] The second liquid inlet channel 211 is a liquid flow path opened on the atomizing seat 21. The second liquid inlet channel 211 is connected to the first liquid inlet channel 15 and is responsible for transporting the aerosol generation matrix to ensure that the aerosol generation matrix smoothly reaches the liquid storage component 22.

[0143] The atomizing assembly 2 comprises three main components: an atomizing base 21, a liquid storage container 22, and an atomizing core 23. The liquid storage container 22 is sandwiched between the atomizing base 21 and the atomizing core 23, making the overall structure of the atomizing assembly 2 more compact. The atomizing base 21 is provided with a second liquid inlet channel 211. The aerosol generation matrix in the first liquid inlet channel 15 can flow into the liquid storage container 22 through the second liquid inlet channel 211, achieving efficient liquid mixing and transportation, providing a stable liquid supply to the atomizing core 23, and ensuring the smooth operation of atomization.

[0144] In one implementation, please refer to Figures 1 to 9 ,

[0145] The liquid storage component 22 includes a first sub-component 221 and a second sub-component 222 arranged sequentially along a first direction of the atomizer 10. The second sub-component 222 is away from the atomizing core 23. The capillary force of the first sub-component 221 is greater than that of the second sub-component 222.

[0146] Capillary force is a force related to the surface tension of a liquid that occurs in capillaries or porous media. Simply put, when a liquid comes into contact with a solid surface, the difference between the cohesive forces between liquid molecules and the adhesive forces between the liquid and solid surface molecules creates a force that causes the liquid to rise or fall in a small space (such as a capillary). This is capillary force. The magnitude of capillary force depends on the pore size of the capillaries formed by the material, the material density, and the type of material itself.

[0147] The liquid storage component 22 is divided into a first sub-component 221 and a second sub-component 222 arranged sequentially along the first direction of the atomizer 10. Given that the capillary force of the first sub-component 221 is greater than that of the second sub-component 222, the flow of the aerosol generation matrix within the liquid storage component 22 exhibits a unique pattern, preferentially filling and flowing through the first sub-component 221, precisely matching the high liquid supply demand of the area near the atomizing core 23.

[0148] Due to its relatively weak capillary force and its location, the second sub-component 222 has poor adsorption capacity for the aerosol generation matrix. When the aerosol generation matrix on the first sub-component 221 is insufficient, the second sub-component 222 will not compete with the first sub-component 221 for the aerosol generation matrix, but will prioritize ensuring that the first sub-component 221 has sufficient aerosol generation matrix, thereby meeting the atomizing core 23's demand for the aerosol generation matrix.

[0149] When there is too much aerosol generating matrix on the first sub-component 221, the second sub-component 222 can absorb the excess aerosol generating matrix, thereby regulating the content of aerosol generating matrix on the first sub-component 221 and keeping it within a suitable suction range, effectively ensuring the suction effect and improving the user experience.

[0150] The first sub-component 221 and the second sub-component 222 are subdivided structures of the liquid storage component 22. They are distributed along the first direction. In this way, the liquid storage component 22 can be set into a structure with different capillary forces in the first direction to meet the actual use requirements.

[0151] It is important to note that the liquid storage component 22 is typically made of liquid storage cotton. For liquid storage cotton, the higher the density, the stronger the adsorption force on the aerosol generating matrix, and the greater the capillary force. In other words, the liquid storage cotton density of the first component 221 is greater than that of the second component 221, and the adsorption force of the first component 221 on the aerosol generating matrix is ​​greater than that of the second component 222.
