Description

TECHNICAL FIELD

[0002] Currently, atomization devices are widely used due to their convenience, but the traditional atomization devices generally have the problem of liquid leakage. The air guide channel of the traditional device is arranged in the base assembly, and the top of the air guide channel is below the liquid storage cavity. This structure design causes the top of the air guide channel to be much lower than the top of the liquid storage cavity. When the device is normally placed, tilted or vibrated by the outside world, the liquid in the liquid storage cavity is easily affected by gravity or air pressure fluctuation, and flows over the top of the air guide channel into the air guide channel, and then flows out from the air inlet connected to the outside, causing waste of liquid. Not only will it pollute the user's hands, clothes and surrounding environment, but also may seep into the internal circuit or other components of the device, causing damage to the components, shortening the service life of the device, and seriously affecting the user experience.

[0028] Reference Figures 1 to 6As shown, the embodiment of the present application provides a liquid leakage prevention atomizing device, which comprises a shell 1, a gas guiding mechanism 2 and an atomizing core mechanism 3; the gas guiding mechanism 2 and the atomizing core mechanism 3 are both installed in the shell 1; a liquid storage cavity 4 is formed between the inner wall of the shell 1 and the outer wall of the gas guiding mechanism 2 and the outer wall of the atomizing core mechanism 3, and the atomizing core mechanism 3 is externally provided with a liquid inlet structure 31 which communicates with the liquid storage cavity 4; the bottom of the gas guiding mechanism 2 is installed at the bottom of the shell 1, the top thereof is close to the upper wall of the liquid storage cavity 4, and a first air inlet channel 21 and a second air inlet channel 22 are arranged in the gas guiding mechanism 2 along the bottom to the top; the bottom of the atomizing core mechanism 3 is installed at the bottom of the shell 1, the top thereof abuts against the upper wall of the liquid storage cavity 4, and an atomizing channel 32 is arranged in the atomizing core mechanism 3 along the bottom to the top; the bottom of the shell 1 is provided with a gas guiding channel 11; the bottom of the first air inlet channel 21 communicates with the outside, the top of the first air inlet channel 21 communicates with the top of the second air inlet channel 22, and the bottom of the second air inlet channel 22 communicates with the bottom of the atomizing channel 32 through the gas guiding channel 11.

[0029] Specifically, by arranging the top of the gas guiding mechanism 2 close to the upper wall of the liquid storage cavity 4, the top of the first air inlet channel 21 and the second air inlet channel 22 is almost consistent with the top of the liquid storage cavity 4, which can fundamentally avoid the liquid in the liquid storage cavity 4 from overflowing the top of the first air inlet channel 21 and the second air inlet channel 22, and meanwhile, the communication relationship between the first air inlet channel 21, the second air inlet channel 22 and the gas guiding channel 11, the atomizing channel 32 can build a stable air flow path, which can ensure that the outside air can enter the atomizing channel 32 through the first air inlet channel 21, the second air inlet channel 22 and the gas guiding channel 11 in sequence, and provide necessary air flow conditions for the atomizing process, and the liquid storage cavity 4 and the liquid inlet structure 31 can provide stable liquid source for the atomizing process, so that the components can work cooperatively to realize the atomizing function and the liquid leakage prevention function of the device.

[0030] In an embodiment, the gas guiding mechanism 2 comprises a first gas guiding pipe 23 and a second gas guiding pipe 24; the first gas guiding pipe 23 penetrates the bottom of the shell 1 in the axial direction, and the first air inlet channel 21 is arranged in the first gas guiding pipe 23 along the axial direction of the first gas guiding pipe 23; the bottom of the second gas guiding pipe 24 is installed at the bottom of the shell 1, the top end thereof is in a sealed state and can abut against the upper wall of the liquid storage cavity 4, the first gas guiding pipe 23 extends into the second gas guiding pipe 24, and the second air inlet channel 11 is formed between the outer wall of the first gas guiding pipe 23 and the inner wall of the second gas guiding pipe 24.

[0031] Specifically, the embodiment can more accurately achieve the setting and function division of the first air inlet channel 21 and the second air inlet channel 22 by splitting the air guide mechanism 2 into two independent components, i.e., the first air guide pipe 23 and the second air guide pipe 24. The first air guide pipe 23 axially penetrates the bottom of the shell 1 and is internally provided with the first air inlet channel 21, thereby ensuring the stable communication of the first air inlet channel 21 with the outside, so that the outside air can smoothly enter the first air inlet channel 21. The second air guide pipe 24 is mounted at the bottom of the shell 1 and is sealed at the top end and can abut against the upper wall of the liquid storage cavity 4. On the one hand, the stability of the position of the second air guide pipe 24 is ensured, and on the other hand, the sealing state of the top end can prevent the liquid in the liquid storage cavity 4 from entering the inside of the second air guide pipe 24 to affect the airflow circulation, and the design of abutting against the upper wall of the liquid storage cavity 4 continues the core idea of preventing liquid leakage. The first air guide pipe 23 extends into the second air guide pipe 24, and the second air inlet channel 22 is formed between the outer wall and the inner wall of the two. This nested structure design not only makes full use of the space inside the device, but also makes the structure of the air guide mechanism 2 more compact, and can ensure the effective communication between the first air inlet channel 21 and the second air inlet channel 22, so as to ensure the smooth transition of the airflow from the first air inlet channel 21 to the second air inlet channel 22, thereby realizing the smoothness of the entire airflow path.

[0032] In an embodiment, the air guide mechanism 2 further comprises a sealing piece 25, which can be sealed to the top end of the second air guide pipe 24 and abut against the upper wall of the liquid storage cavity 4.

[0033] Specifically, the addition of the sealing piece 25 significantly improves the sealing performance of the top end of the air guide mechanism 2, eliminates the risk of liquid in the liquid storage cavity 4 entering the inside of the air guide pipe through the top end of the second air guide pipe 24 or leaking from the gap between the two, and further enhances the liquid leakage prevention effect of the device, thereby providing users with more secure and reliable use protection.

[0034] In an embodiment, one end of the sealing piece 25 away from the second air guide pipe 24 is provided with a positioning groove 251, and the upper wall of the liquid storage cavity 4 extends downwardly to have a positioning portion 41, which extends into the positioning groove 251.

[0035] Specifically, by arranging the positioning groove 251 on the sealing element 25 and the downwardly extending positioning portion 41 on the upper wall of the liquid storage cavity 4, and by using the cooperation mode of the positioning portion 41 extending into the positioning groove 251, the accurate positioning and fixing between the sealing element 25 and the upper wall of the liquid storage cavity 4 can be achieved. This positioning structure can ensure that the sealing element 25 and the second air guide tube 24 connected thereto can be accurately placed at the preset position during installation, avoiding the installation deviation or misplacement of the sealing element 25 and the second air guide tube 24, so as to ensure that the sealing element 25 can accurately seal the top end of the second air guide tube 24 and tightly abut against the upper wall of the liquid storage cavity 4, thereby continuously playing the role of sealing and preventing liquid leakage. In addition, the design of this positioning structure also provides convenience for the assembly process of the device. The assembler can quickly find the installation position of the sealing element 25 through the cooperation of the positioning portion 41 and the positioning groove 251, thereby improving the assembly efficiency of the device and ensuring the consistency and reliability of each assembled device.

[0036] Further, the buffer chamber 26 is formed between the top of the first air inlet channel 21 and the top of the second air inlet channel 22, which can buffer the flow rate and pressure of the airflow when entering the second air inlet channel 22 from the first air inlet channel 21, avoid the sudden change of air pressure caused by direct impact of the airflow, and make the airflow enter the second air inlet channel 22 smoothly, thereby ensuring the uniformity of the air inlet of the atomization channel 32 and improving the stability of atomization. At the same time, if a small amount of liquid accidentally enters the second air inlet channel 22, the buffer chamber 26 can temporarily store the liquid to prevent it from flowing into the first air inlet channel 21, thereby further enhancing the oil leakage prevention effect without affecting the normal airflow.

[0037] In an embodiment, the housing 1 includes an upper shell 12 and a base assembly 13; the base assembly 13 is detachably connected to the bottom opening 121 of the upper shell 12; the bottom of the air guide mechanism 2 and the bottom of the atomization core mechanism 3 are both installed on the base assembly 13; the air guide channel 11 is arranged in the base assembly 13; and the liquid storage cavity 4 is formed between the inner wall of the upper shell 12, the upper wall of the base assembly 13, the outer wall of the air guide mechanism 2, and the outer wall of the atomization core mechanism 3.

[0038] Specifically, the detachable shell 1 structure composed of the upper shell 12 and the base assembly 13 greatly improves the maintainability and use convenience of the device. Users can easily disassemble the base assembly 13 for maintenance, replacement of internal components, and cleaning and liquid replenishment of the liquid storage cavity 4, reducing the user's use difficulty and maintenance cost, and improving the user's use experience. Secondly, the air guide mechanism 2 and the atomizing core mechanism 3 form independent modules on the base assembly 13, facilitating pre-assembly and debugging during production, improving production efficiency and product quality stability, and also providing convenience for later maintenance and replacement, reducing the workload and time during maintenance. The air guide channel 11 is arranged in the base assembly 13, ensuring the structural stability and connection accuracy of the air guide channel 11, avoiding the problem of poor air flow caused by position deviation or loose connection of the air guide channel 11, and ensuring the stable realization of the atomization function of the device. In addition, the reasonable structure design of the liquid storage cavity 4 ensures sufficient liquid storage capacity, reduces the frequency of liquid replenishment by users, and also facilitates smooth entry of liquid into the atomizing core mechanism 3, providing continuous and stable liquid supply for the atomization process, further ensuring the stable and efficient work of the atomization device.

[0039] Further, the base assembly 13 is provided with a liquid suction member 131, and the liquid suction member 131 is located at the bottom end of the atomizing channel 32. The liquid suction member 131 can adsorb the liquid leaked at the bottom end of the atomizing channel 32, avoid liquid accumulation or outflow of the device, strengthen the oil leakage prevention effect, and prevent liquid from damaging the components in the base assembly 13, prolonging the service life of the device.

[0040] In an embodiment, the upper wall of the liquid storage cavity 4 is connected with a sealing ring 42, the top of the atomizing core mechanism 3 is arranged in the sealing ring 42, and is connected with the sealing ring 42 in an axial sliding manner. When the base assembly 13 is partially embedded in the bottom opening 121 of the upper shell 12, the liquid inlet structure 31 is in a completely open state. When the base assembly 13 is completely embedded in the bottom opening 121 of the upper shell 12, the liquid inlet structure 31 is partially covered by the sealing ring 42.

[0041] Specifically, the upper wall of the liquid storage cavity 4 is connected with a sealing ring 42, and the top of the atomization core mechanism 3 is arranged in the sealing ring 42 and connected in axial sliding manner, mainly to control the conduction state of the liquid inlet structure 31 by embedding the base assembly 13 into the bottom opening 121 of the upper shell 12 to different degrees, so as to adjust the flow of liquid into the atomization core mechanism 3. When the base assembly 13 is partially embedded into the bottom opening 121 of the upper shell 12, the atomization core mechanism 3 moves with the base assembly 13, and the top thereof is relatively low in the sealing ring 42, so that the liquid inlet structure 31 can be completely exposed and be in a fully conductive state. At this time, the liquid in the liquid storage cavity 4 can enter the atomization core mechanism 3 in a large amount through the liquid inlet structure 31, meeting the demand of the device in a high-load working state. When the base assembly 13 is completely embedded into the bottom opening 121 of the upper shell 12, the atomization core mechanism 3 moves upward with the base assembly 13, and the top thereof slides upward in the sealing ring 42, causing the sealing ring 42 to partially cover the liquid inlet structure 31, so that the conduction area of the liquid inlet structure 31 is reduced, and the flow of liquid into the atomization core mechanism 3 is correspondingly reduced. This design can flexibly adjust the liquid inlet amount according to different use conditions and working loads of the device, avoid liquid accumulation in the atomization core mechanism 3 due to excessive liquid inlet amount, and thus cause liquid leakage or insufficient atomization, and also can reduce liquid consumption and improve the utilization rate of liquid when the device works in a low-load state.

[0042] Further, the upper end of the upper shell 12 extends into the liquid storage cavity 4 with a suction nozzle 122, the lower end of the suction nozzle 122 extends into the annular sealing plug 38 arranged at the top of the atomization core mechanism 3, and the upper end of the sealing ring 42 is connected to the outer side of the suction nozzle 122.

[0043] Specifically, the lower end of the suction nozzle 122 extends into the annular sealing plug 38 at the top of the atomization core mechanism 3 to form a sealing structure, which not only prevents the liquid in the liquid storage cavity 4 from seeping into the atomization channel 32 to cause oil leakage, but also avoids the escape of atomized gas from the gap to ensure concentrated mist output. The suction nozzle 122 also provides guidance for the axial movement of the atomization core mechanism 3 to ensure accurate sliding. The upper end of the sealing ring 42 is connected to the outer side of the suction nozzle 122 to enhance the installation stability thereof, guarantee the regulation accuracy of the liquid inlet structure 31, and further improve the sealing performance and working stability of the device.

[0044] It can be understood that the sealing ring 42 can be sleeved on the outer side of the suction nozzle 122 or integrally formed with the suction nozzle 122. The sleeving type facilitates the separate replacement and maintenance of the sealing ring 42, and reduces the cost. The integral forming type improves the connection sealing performance and structural stability, reduces the assembly error, and is suitable for different production and use requirements to enhance the design flexibility.

[0045] Further, the atomization core mechanism 3 has a sealing protrusion 39 extending outwardly at one end close to the mouthpiece 122, and the sealing ring 42 is sleeved on the sealing protrusion 39. The sealing protrusion 39 can reduce the gap between the sealing ring 42 and the atomization core mechanism 3, enhance the adhesion between the two, improve the sealing effect, and prevent liquid leakage from the gap. At the same time, this structure can limit the radial displacement of the sealing ring 42, ensure the accurate coverage and regulation of the sealing ring 42 on the liquid inlet structure 31, and further ensure the oil leakage prevention performance and liquid inlet control stability of the device under different working conditions.

[0046] In an embodiment, the liquid inlet structure 31 includes at least a first liquid inlet hole 311 and a second liquid inlet hole 312. The first liquid inlet hole 311 is arranged close to the sealing ring 42, and the second liquid inlet hole 312 is arranged away from the sealing ring 42. When the base assembly 13 is partially inserted into the bottom opening 121 of the upper shell 12, both the first liquid inlet hole 311 and the second liquid inlet hole 312 are in a conductive state. When the base assembly 13 is completely inserted into the bottom opening 121 of the upper shell 12, the first liquid inlet hole 311 is covered by the sealing ring 42, and the second liquid inlet hole 312 remains in a conductive state.

[0047] Specifically, the present embodiment realizes stepwise adjustment of the liquid inlet amount by designing the liquid inlet structure 31 with the first liquid inlet hole 311 and the second liquid inlet hole 312. When the device needs a large amount of liquid supply, both liquid inlet holes are simultaneously in a conductive state, which can quickly provide sufficient liquid to the atomization core mechanism 3, ensure the stable operation of the device under high-power and high-load working conditions, and guarantee the atomization effect. When the device is in a low-load working condition or does not need a large amount of liquid, only the second liquid inlet hole 312 is in a conductive state, which reduces the amount of liquid entering, avoids the accumulation of liquid in the atomization core mechanism 3, effectively prevents liquid leakage, and also reduces the consumption speed of the liquid, prolongs the use time after single liquid addition, and improves the utilization rate of the liquid. Secondly, this design makes the adjustment method of the liquid inlet amount more simple and intuitive, which can be realized by only changing the degree of embedding of the base assembly 13 into the upper shell 12, without the need for additional complex adjustment mechanisms, thereby reducing the structural complexity and production cost of the device and facilitating the operation and use of the user. In addition, the arrangement of the two liquid inlet holes provides double protection for the liquid inlet safety of the device. Even if one of the liquid inlet holes cannot normally conduct due to unexpected circumstances (such as impurity blockage), the other liquid inlet hole can still maintain a working state, ensuring that the atomization core mechanism 3 will not stop working due to liquid interruption, and improving the continuity and reliability of the device working.

[0048] Preferably, the number of the first liquid inlet hole 311 and the second liquid inlet hole 312 is multiple, and they are circumferentially distributed on the outer wall of the atomization core mechanism 3, thereby realizing uniform liquid supply.

[0049] Further, the liquid inlet structure 31 comprises at least a first liquid inlet hole 311 and a second liquid inlet hole 312, and the upper shell 12 and the base assembly 13 are connected at least at a first clamping position and a second clamping position in the axial direction, the first clamping position is axially away from the sealing ring, and the second clamping position is axially close to the sealing ring; when the first liquid inlet hole 311 and the second liquid inlet hole 312 are both in the open state, the upper shell 12 and the base assembly 13 are tightly connected at the first clamping position, thereby accurately fixing the position of the base assembly 13 and ensuring that the liquid inlet hole is completely open; when the first liquid inlet hole 311 is covered by the sealing ring 42 and the second liquid inlet hole 312 remains in the open state, the upper shell 12 and the base assembly 13 are tightly connected at the second clamping position (or both at the first clamping position and the second clamping position), thereby stabilizing the base assembly 13 and ensuring that the first liquid inlet hole 311 is accurately covered by the sealing ring 42. This structure does not require additional adjusting parts, and the liquid inlet state can be accurately switched through clamping positioning, avoiding abnormal liquid inlet caused by displacement of the base assembly 13, improving the stability of use, and at the same time, the user can clearly know the current liquid inlet state through the clamping feedback, and the operation is more convenient.

[0050] In an embodiment, the outer surface of the atomizing core mechanism 3 is embedded with a first sealing ring 33 above the first liquid inlet hole 311 in the axial direction and a second sealing ring 34 below the first liquid inlet hole 311 in the axial direction; when the first liquid inlet hole 311 and the second liquid inlet hole 312 are both in the open state, the inner side of the sealing ring 42 abuts against the first sealing ring 33, preventing liquid from leaking from the gap between the sealing ring 42 and the atomizing core mechanism 3, and ensuring reliable sealing during large-flow liquid supply; when the first liquid inlet hole 311 is covered by the sealing ring 42 and the second liquid inlet hole 312 remains in the open state, the inner side of the sealing ring 42 abuts against the first sealing ring 33 and the second sealing ring 34, double sealing enhances the leakage prevention effect, and prevents liquid from seeping from the gap around the first liquid inlet hole 311; and this structure does not require complex parts, and through the cooperation of the sealing ring and the sealing ring 42, the sealing stability under different working conditions is improved, and the leakage prevention and structural simplicity are considered.

[0051] In an embodiment, the first liquid inlet hole 311 and the atomizing channel 32 are provided with a first liquid storage medium 35; the second liquid inlet hole 312 and the atomizing channel 32 are provided with a second liquid storage medium 36; and the top of the second liquid storage medium 36 abuts against the bottom of the first liquid storage medium 35.

[0052] Specifically, the embodiment achieves the layered storage and gradient liquid supply of the liquid by setting two kinds of liquid storage media abutting each other, and adapts to the conduction state of different liquid inlet holes. When the base assembly 13 is partially embedded in the upper shell 12 and the first liquid inlet hole 311 and the second liquid inlet hole 312 are both conductive, the liquid in the liquid storage cavity 4 enters the corresponding liquid storage medium through the two liquid inlet holes, respectively. The first liquid storage medium 35 and the second liquid storage medium 36 store the liquid together, and supply the liquid to the atomization channel 32 uniformly through their own adsorption and conduction characteristics, meeting the large demand for liquid when the device works under high load. When the base assembly 13 is completely embedded in the upper shell 12 and only the second liquid inlet hole 312 is conductive, the liquid enters the second liquid storage medium 36 through the second liquid inlet hole 312. Since the top of the second liquid storage medium 36 abuts the bottom of the first liquid storage medium 35, the liquid in the second liquid storage medium 36 can slowly infiltrate the first liquid storage medium 35 through capillary action, so that the first liquid storage medium 35 always remains wet, avoiding the dryness of the corresponding liquid storage medium of the first liquid inlet hole 311 due to the covering of the sealing ring 42, and further affecting the atomization effect. In addition, the porous structure of the liquid storage medium has good liquid retention capacity, which can slow down the flow speed of the liquid to the atomization channel 32, preventing the liquid from quickly flowing into the atomization channel 32 due to gravity, resulting in insufficient atomization or liquid leakage.

[0053] It can be understood that the atomization core mechanism 3 further includes a heating assembly 37, and the first liquid storage medium 35 and the second liquid storage medium 36 are wrapped around the upper half and the lower half of the heating assembly 37, respectively, so as to stably supply the liquid to the heating assembly 37. The heating assembly 37 heats the liquid, thereby atomizing the liquid, and the atomized liquid is discharged from the atomization channel 32, thereby supporting the normal atomization work of the atomization device.

[0054] In an embodiment, the outer surface of the second liquid storage medium 36 is inwardly recessed to form an air exchange groove 361, and the air exchange groove 361 communicates with any second liquid inlet structure 31.

[0055] Specifically, the embodiment solves the air pressure balance problem in the process of liquid entering the second liquid storage medium 36 by setting the air exchange groove 361. When the liquid enters the second liquid storage medium 36 through the second liquid inlet hole 312, the air inside the second liquid storage medium 36 will be squeezed by the liquid. If the air cannot be discharged in time, it will form air pressure resistance inside the medium, hindering the liquid from continuing to enter, resulting in slow or unsmooth liquid inlet. The setting of the air exchange groove 361 provides a dedicated channel for air discharge. The squeezed air can flow to the second liquid inlet hole 312 through the air exchange groove 361, and then enter the liquid storage cavity 4 through the second liquid inlet hole 312, realizing air pressure balance between the inside of the second liquid storage medium 36 and the liquid storage cavity 4, and ensuring that the liquid can enter the second liquid storage medium 36 smoothly and quickly. At the same time, the air exchange groove 361 adopts an inwardly recessed structure design, which is only formed on the outer surface of the second liquid storage medium 36, does not damage the overall structural integrity of the second liquid storage medium 36, and does not occupy additional space inside the device, ensuring the normal cooperation of the liquid storage medium with other components (such as the first liquid storage medium 35 and the sealing ring 42).

[0056] Preferably, the number of air exchange grooves 361 is multiple, and they are arranged in a circumferential distribution, thereby realizing uniform liquid supply.

[0057] Further, the inner side of the first liquid storage medium 35 and the second liquid storage medium 36 is provided with a ring-shaped fixing member 310. The ring-shaped fixing member 310 has an air hole 3101 at a position corresponding to the first liquid storage medium 35. The air hole 3101 is connected to the outside and is connected to the air exchange groove 361 through the air gap of the first liquid storage medium 35.

[0058] Specifically, the ring-shaped fixing member 310 is located outside the heating assembly 37, and a third liquid storage medium 371 is arranged between the heating assembly 37 and the ring-shaped fixing member 310. The air hole 3101 is connected to the outside through the air gap of the third liquid storage medium 371 and the atomization channel 32, thereby connecting to the outside. The air hole 3101 cooperates with the air exchange groove 361 to quickly balance the air pressure inside and outside the atomization core mechanism 3, thereby avoiding the difficulty of liquid entering due to air pressure resistance and preventing the interruption of liquid supply caused by negative pressure. The air hole 3101 is connected to the outside through the atomization channel 32, without the need for additional holes, thereby simplifying the structure. The ring-shaped fixing member 310 can also fix the relative position of the liquid storage medium and the heating assembly 37, ensuring stable communication between the air gap and the air hole 3101 and the air exchange groove 361, ensuring continuous and effective air pressure balance, thereby maintaining stable liquid supply and preventing dry burning and liquid leakage.

[0059] Further, the width of the air exchange groove 361 gradually narrows from the outermost side of the second liquid storage medium 36 to the inside, which can guide the external air to enter the liquid storage cavity 4 uniformly along the air exchange groove 36, avoid the concentrated inflow of air to generate a large number of air bubbles, reduce the interference of air bubbles on the liquid supply, and slow down the air flow rate to make the air pressure balance process more stable, thereby further ensuring the smoothness and stability of the liquid inflow.

[0060] In an embodiment, the size of the first liquid inlet hole 311 is larger than that of the second liquid inlet hole 312.

[0061] Specifically, according to the different working scenes and functional positioning of the two liquid inlet holes, the size difference is used to realize the precise regulation of the liquid inflow. The first liquid inlet hole 311 is close to the sealing ring 42 and is only open when the base assembly 13 is partially embedded in the upper shell 12, and is mainly used for large-flow liquid supply in high-load working scenes of the device, so a larger size is needed to improve the liquid inflow speed and ensure that the liquid in the liquid storage cavity 4 can quickly enter the atomizing core mechanism 3 to meet the large demand of high-power atomization for liquid. The second liquid inlet hole 312 is away from the sealing ring 42 and remains open when the base assembly 13 is partially embedded or completely embedded in the upper shell 12, which needs to assist the first liquid inlet hole 311 to increase the total liquid inflow in high-load scenes and needs to supply liquid to the atomizing core mechanism 3 alone in low-load scenes. A smaller size can effectively control the liquid inflow in low-load scenes to avoid excessive liquid supply and accumulation in the atomizing core mechanism 3, thereby causing liquid leakage or insufficient atomization. In addition, the design of different sizes also facilitates the identification and assembly of parts during production, reduces assembly errors caused by confusion of liquid inlet holes, and improves production efficiency.

[0062] Further, the outer shell 1 is provided with a liquid injection hole 14 communicating with the liquid storage cavity 4, and a liquid injection plug 15 is inserted into the liquid injection hole 14. When the first liquid inlet hole 311 and the second liquid inlet hole 312 are both in the open state, liquid is injected into the liquid storage cavity 4 through the liquid injection hole 14, and at this time the liquid quickly enters the inside of the atomizing core mechanism 3 from the liquid storage cavity 4 through the first liquid inlet hole 311 and the second liquid inlet hole 312; after the liquid injection is completed, the liquid injection hole 14 is sealed by the liquid injection plug 15, and after the first liquid storage medium 35 and the second liquid storage medium 36 are both infiltrated by the liquid, the base assembly 13 is pushed upwards to close the first liquid inlet hole 311. The liquid injection hole 14 provides a convenient channel for supplementing the liquid in the liquid storage cavity 4 without disassembling the device, simplifying the liquid injection operation; the liquid injection plug 15 can tightly plug the liquid injection hole 14, which not only prevents the liquid in the liquid storage cavity 4 from leaking, but also blocks the entry of external impurities, thereby ensuring the sealing and internal cleanliness of the device.

[0063] The above embodiments are the preferred implementation schemes of the present application, and in addition to this, the present application can also be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
