Description

Technical Field

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

[0002] Electronic atomizing devices utilize their atomizing core assembly to heat and atomize the atomizing matrix to form an aerosol, which is then used by the user for inhalation. Because the atomizing core assembly has a limited lifespan, when the liquid storage chamber of the electronic atomizing device is small, the amount of atomizing matrix stored inside is limited, failing to meet the lifespan of the atomizing core assembly, thus wasting it. Conversely, when the liquid storage chamber of the electronic atomizing device is large, it does not meet the requirements for liquid storage chamber volume in some regions and increases the distance between the atomizing core assembly and the inhalation point, affecting the taste of the aerosol. Utility Model Content

The atomizer is disposed within the housing assembly; the atomizer has a liquid storage chamber and an atomization chamber. The liquid storage chamber stores an atomizing matrix, and the atomization chamber contains an atomizing core for heating the atomizing matrix to generate an aerosol. The liquid replenishment assembly stores the atomizing matrix and replenishes it to the liquid storage chamber. The liquid replenishment assembly has an air inlet for connecting it to the external environment to balance the air pressure inside and outside the liquid replenishment assembly. The pumping mechanism is disposed within the housing assembly; the pumping mechanism has an inlet end and an outlet end. The inlet end communicates with the liquid replenishment assembly, and the outlet end communicates with the liquid storage chamber, for transferring the atomizing matrix from the liquid replenishment assembly to the liquid storage chamber.

[0009] In some optional embodiments, the housing assembly includes an outer shell and an inner support, the inner support being disposed within the outer shell; the inner support has a first protrusion and a second protrusion on the side opposite to the fluid replenishment assembly, the second protrusion being disposed inside the first protrusion and spaced apart from the first protrusion to form the sensing cavity, the second protrusion having a first through hole to form the main airway, and the side of the second protrusion having a second through hole to form the negative pressure sensing airway.

[0010] In some optional embodiments, an air supply plug is movably provided at the air supply port, the air supply plug being used to block or open the air supply port; the end of the air supply port that communicates with the liquid supply component is provided with multiple ventilation holes.

[0011] In some optional embodiments, the housing assembly is provided with a first observation window, a second observation window and a third observation window.

[0030] 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.

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.

[0031] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0032] The serial numbers assigned to components in this document, such as "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0033] Before introducing the technical solution of this application, some terms used in this application will be explained.

[0034] "Aerosol" refers to a dispersion of solid or liquid particles in a gas. As used in this article, "aerosol" can generally refer to a substance that has been vaporized, aerosolized, sprayed or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0035] The atomizing matrix in this application is any suitable compound or mixture of compounds that facilitates aerosol formation during use, including but not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. It may also include nicotine, water, glycerol (also known as glycerol) having a higher boiling point than nicotine, propylene glycol, plant-based materials, or homogeneous plant substrates. The atomizing matrix is ​​generally a liquid with fluidity, which can be stored directly in a container or adsorbed and stored in a porous structure (e.g., absorbent cotton or porous ceramics).

[0036] Please see Figures 1 to 8 This application provides an electronic atomizing device 1, which is an apparatus capable of heating an atomizing substrate to generate an aerosol. The atomizing device includes a housing assembly 10, a power supply assembly 50, and an atomizer 20. The power supply assembly 50 is mainly used to supply power to the atomizer 20, and the atomizer 20 is mainly used to heat the atomizing substrate to generate an aerosol after being powered on.

[0037] In some embodiments, the atomizer 20 is an ultrasonic atomizer that generates an aerosol by atomizing the matrix through high-frequency vibration.

[0038] In some embodiments, the atomizer 20 and the power supply component 50 are integrated through the housing component 10, which reduces the corresponding assembly structure between the atomizer 20 and the power supply component 50, and also reduces the overall size of the electronic atomization device 1, thereby lowering the production cost of the electronic atomization device 1 and making it highly promising for widespread application. Of course, in other embodiments, the atomizer 20 and the power supply component 50 can also be designed as separate structures, for example, the atomizer 20 and the power supply component 50 can be detachably electrically connected by magnetic attraction (not shown in the figure).

[0039] Please see Figure 2The atomizer 20 includes an atomizing housing 21 and an atomizing core 22. The atomizing housing 21 is disposed inside the housing assembly 10. The atomizing housing 21 has a liquid storage chamber 211 and an atomizing chamber 212. The liquid storage chamber 211 stores the atomizing matrix, and the atomizing core 22 is disposed within the atomizing chamber 212. The atomizing core 22 is used to heat the atomizing matrix to generate an aerosol. The atomizing core 22 generally has a limited lifespan; that is, after heating a certain volume of atomizing matrix, the atomizing core 22 cannot continue to be used and needs to be disposed of. Due to legal limitations in some regions (such as maximum capacity requirements for atomizers in Europe), the volume of the liquid storage chamber 211 is relatively small. Consequently, the atomizing matrix in the liquid storage chamber 211 may not reach the lifespan of the atomizing core 22. After the atomizing matrix in the liquid storage chamber 211 is exhausted, the entire electronic atomizing device 1 or the entire atomizer 20 needs to be disposed of, increasing the user's operating costs.

[0040] To address the issue of the small volume of the liquid storage chamber 211, while avoiding increasing its size to prevent impacting the overall size of the electronic atomizing device 1 and the aerosol's flavor, this embodiment of the electronic atomizing device 1 further includes a replenishment component 30. This component 30 is connected to the liquid storage chamber 211 via a liquid passage 60, allowing for the replenishment of new atomizing matrix after its depletion. This ensures the lifespan of the atomizing core 22 is maintained and that the atomizing core 22's positioning guarantees the aerosol's flavor. The volume of the replenishment component 30 can be adjusted as needed. Furthermore, to reduce the overall size of the electronic atomizing device 1, a liquid inlet can be provided on the replenishment component 30. This inlet allows the user to replenish the liquid via an external replenishment component. The inlet can be sealed with a plug when not in use.

[0041] It should be understood that the liquid channel 60 is a fluid transmission system connecting the replenishment component 30 and the storage chamber 211, used to realize the directional transfer of the atomized matrix from the replenishment component 30 to the storage chamber 211. The liquid channel 60 is the entire process fluid transmission path and related components, including but not limited to pipes, valves, interfaces, pumps, filters and other components.

[0042] Please continue reading. Figure 2 , Figure 2The dashed box in the figure marks the liquid channel 60, and the arrows in the figure indicate the actual flow direction of the atomized matrix. The liquid channel 60 includes a pumping mechanism 40, which, once activated, automatically and continuously transfers the atomized matrix from the replenishment component 30 to the storage chamber 211, thereby replenishing the storage chamber 211 with atomized matrix. The pumping mechanism 40 is located within the housing assembly 10 and has an inlet end 41 and an outlet end 42. The inlet end 41 communicates with the replenishment component 30, and the outlet end 42 communicates with the storage chamber 211, thus transferring the atomized matrix from the replenishment component 30 to the storage chamber 211. The pumping mechanism 40 increases the injection rate of the replenishment component 30. Furthermore, the pumping mechanism 40 itself has a good fluid shut-off function even when not activated, thus preventing leakage in the liquid channel 60.

[0043] In some embodiments, the atomizing matrix in the liquid storage chamber 211 and the liquid replenishment component 30 can be the same type of atomizing matrix or different types of atomizing matrices, allowing users to enjoy different flavors on the same electronic atomizing device 1, thereby improving the user experience. Specifically, based on taste preferences, different flavor additives, such as sweeteners and cooling agents, can be added to the basic atomizing matrix to achieve different flavors. Alternatively, functional additives, such as ginseng extract, royal jelly, and goji berry extract, can be added according to user needs, providing a personalized and diversified user experience.

[0044] As the atomizing matrix is ​​transferred from the replenishing component 30 to the storage chamber 211, the liquid level inside the replenishing component 30 gradually decreases. When the replenishing component 30 is a closed structure, the internal air pressure decreases as the liquid level decreases, leading to an imbalance in air pressure inside and outside the replenishing component 30, which affects the subsequent transfer speed of the atomizing matrix. Please continue reading. Figure 2 The liquid replenishment component 30 is provided with an air replenishment port 31, which is used to connect the liquid replenishment component 30 with the external environment to balance the air pressure inside and outside the liquid replenishment component 30, so that the air pressure inside the liquid replenishment component 30 is always kept below atmospheric pressure. This allows the atomizing matrix to be smoothly transferred based on the pressure difference between the liquid replenishment component 30 and the liquid storage chamber 211, ensuring sufficient liquid supply to the atomizing matrix and avoiding the burning phenomenon caused by insufficient liquid supply (the atomizing core 22 burns dry and produces a burnt smell).

[0045] In some embodiments, in order to simplify the structure of the electronic atomizing device 1, the liquid injection port and the air replenishment port 31 can be combined into one, that is, an opening is provided on the liquid replenishment component 30, which serves as both the liquid injection port and the air replenishment port 31.

[0046] In other embodiments, the air inlet 32 ​​has a smaller aperture and the characteristic of allowing air to pass through but not liquid, so that it can play a role in air exchange without causing the atomized matrix to leak from the air inlet 32.

[0047] In some embodiments, the gas inlet 31 is provided with a gas inlet plug 32, which is movable relative to the gas inlet 31 and is used to open or close the gas inlet 31. Thus, when gas or liquid needs to be replenished, the gas inlet plug 32 is moved to open the gas inlet 31, and after the gas replenishment or liquid injection is completed, the gas inlet plug 32 is moved again to close the gas inlet 31, so as to avoid liquid leakage from the gas inlet 31.

[0048] In some embodiments, please refer to Figure 3 The air inlet 31, connected to the liquid replenishment component 30, has multiple ventilation holes 311 at one end. These ventilation holes 311 are evenly distributed around the circumference of the air inlet 31, for example, they can be arranged in a ring array or a honeycomb pattern. The inner diameter of the ventilation holes 311 is smaller than the inner diameter of the air inlet 31. The multiple ventilation holes 311 can synchronously adjust the air pressure at multiple points to ensure dynamic pressure balance inside and outside the liquid replenishment component 30, avoiding liquid backflow or spraying caused by excessive pressure difference, thereby ensuring the stability of the atomized matrix replenishment process.

[0049] Please continue reading. Figure 2 The housing assembly 10 is an assembly of multiple components, internally forming cavities and a fixed assembly structure. For example... Figure 2 As shown, both the power supply component 50 and the atomizer 20 are housed within the cavity of the housing component 10 and are fixed in place by a mating structure. Simultaneously, at least a portion of the power supply component 50 is exposed outside the housing component 10, allowing the user to control the operating status of the electronic atomizing device 1. The housing component 10 facilitates the overall portability and mobility of the electronic atomizing device 1.

[0050] In some embodiments, the housing assembly 10 may be made of a high-temperature resistant plastic material or a metallic material, such as an aluminum alloy.

[0051] In one embodiment, at least a portion of the housing assembly 10 is a transparent structure, where a display screen can be installed, or the transparent structure can be used to expose at least a portion of the replenishment assembly 30 and the atomizer 20 so that the user can view the status of the various structural components inside the electronic atomization device 1 as shown in the accompanying drawings. For example, the user can view the remaining amount of atomizing matrix in the replenishment assembly 30 through the aforementioned transparent structure (not shown in the figures); the user can also view the remaining amount of atomizing matrix in the atomizer 20 through the aforementioned transparent structure (not shown in the figures).

[0052] Please see Figure 4The housing assembly 10 includes an outer shell 11 and an inner support 12. The inner support 12 is disposed within the outer shell 11 and divides the outer shell 11 into a first chamber 14, a second chamber 15, and a third chamber 16. The atomizer 20 is disposed within the first chamber 14, the liquid replenishment assembly 30 is disposed within the second chamber 15, and the pumping mechanism 40 is disposed within the third chamber 16. The inner support 12 allows for the independent placement of the atomizer 20, the liquid replenishment assembly 30, and the pumping mechanism 40, while also serving as a support and assembly structure for these components. This simplifies the structure of the housing assembly 10 and its internal assembly, thereby reducing the production cost, manufacturing difficulty, and assembly difficulty of the electronic atomization device 1. To simplify the structure, a portion of the inner support 12 is directly constructed as the liquid replenishment assembly 30. In some specific embodiments, the inner support 12 forms a second cavity 15, and a separate chamber can be set in the second cavity 15 to construct a liquid replenishment component 30. Alternatively, the second cavity 15 can directly contain the atomizing matrix, that is, the inner support 12 is equivalent to the chamber of the liquid replenishment component 30.

[0053] In some embodiments, the housing assembly 10 is provided with an air inlet 131, which communicates with the external environment; the second cavity 15 is provided with an airflow channel 151, which is located in the middle of the liquid replenishment assembly 30 and isolated from it, and the airflow channel 151 connects the air inlet 131 and the atomizing chamber 212. Through the arrangement of the air inlet 131 and the airflow channel 151, when the user inhales, outside air can flow sequentially into the atomizing chamber 212 along the air inlet 131 and the airflow channel 151, mix with the aerosol in the atomizing chamber 212, and then flow out of the electronic atomizing device 1 along the atomizing chamber 212.

[0054] Please continue reading. Figure 4 The outer casing 11 has a mounting opening 112, and a mouthpiece 111 is provided at the other end opposite the mounting opening 112 along the axial direction of the atomizing chamber 212. The mouthpiece 111 communicates with the atomizing chamber 212, and the aerosol generated in the atomizing chamber 212 is discharged to the outside of the electronic atomizing device 1 through the mouthpiece 111. In other words, the user can also obtain the aerosol generated in the atomizing chamber 212 through the mouthpiece 111. The mouthpiece 111 and the outer casing 11 can be an integral structure or a separate structure. In the embodiment where the mouthpiece 111 and the outer casing 11 are separate structures, the mouthpiece 111 can be disassembled independently for cleaning, which can improve the taste of the aerosol.

[0055] In some embodiments, the housing assembly 10 further includes a base 13 disposed at the mounting opening 112. After the atomizer 20, power supply assembly 50, pumping mechanism 40, liquid replenishment assembly 30, and inner support 12 are installed inside the housing 11, the base 13 closes the mounting opening 112 and secures the inner support 12, atomizer 20, power supply assembly 50, pumping mechanism 40, and liquid replenishment assembly 30. Specifically, the end of the base 13 engages with the inner wall of the housing 11 to secure the inner support 12 inside the housing 11, thereby achieving a fixed assembly of the atomizer 20, pumping mechanism 40, and liquid replenishment assembly 30 mounted on the inner support 12. In some embodiments, the base 13 has a hollow structure and is inserted into the housing 11 through the mounting opening 112. After the end of the base 13 abuts against the inner support 12, a fourth cavity 17 is formed between the base 13 and the inner support 12, and the power supply assembly 50 is mounted in the fourth cavity 17. The internal support 12 separates the power supply component 50 from the liquid replenishment component 30, the pumping mechanism 40, and the atomizer 20, preventing leakage of the atomizing matrix or condensate to the power supply component 50, which could corrode or damage it. In some embodiments, the air inlet 131 is located on the base 13.

[0056] In some embodiments, the power supply component 50 includes a battery 51 and a circuit board 52. The battery 51 provides the power required for the atomizer 20 to operate, and the circuit board 52 controls the operation of the atomizer 20, i.e., turns the atomizer 20 on or off. In some specific embodiments, the circuit board 52 can also adjust the operating power of the atomizer 20 to heat the atomizing matrix at different heating temperatures, thereby obtaining different aerosol generation amounts. For example, the circuit board 52 can control the number of heating elements in the atomizing core 22 to achieve different operating power adjustments.

[0057] To enhance the convenience of the electronic atomizing device 1, it also includes a sensing channel 126 and a sensing cavity 125. An airflow sensor 53 is installed inside the sensing cavity 125. The sensing channel 126 communicates with the sensing cavity 125 and is also connected to the atomizing cavity 212 via an airflow channel 151. The sensing channel 126 and sensing cavity 125 can be positioned anywhere within the housing assembly 11, for example, in the mouthpiece 111, inside the atomizer 20, inside the liquid replenishment assembly 30, or on the side of the liquid replenishment assembly 30 facing away from the atomizer 20. The sensing channel 126 communicates with the mouthpiece 111. During inhalation, the airflow sensor 53 detects changes in ambient negative pressure, and further determines whether to activate the atomizer 20 based on whether the amount of negative pressure change exceeds a preset value.

[0058] In some embodiments, the sensing channel 126 and the sensing cavity 125 are disposed on the inner support 12 and on the side of the inner support 12 facing away from the liquid replenishment assembly 30. The airflow sensor 53 is electrically connected to the circuit board 52. When the user inhales, outside air enters the atomizing chamber 212 from the air inlet 131 through the airflow channel 151. Since the sensing channel 126 is disposed on the connecting path between the air inlet 131 and the airflow channel 151, air can also quickly pass through the sensing channel 126 and the sensing cavity 125, thereby triggering the airflow sensor 53 to output a corresponding electrical signal. After the circuit board 52 obtains the electrical signal, it triggers the atomizer 20 to start or stop according to the electrical signal. The airflow sensor 53 may include a pressure sensor and a MEMS airflow sensor. The airflow sensor 53 includes a sensing body and a sealing sleeve. One side of the sensing body is disposed on the circuit board 52, and the other side is covered by the sealing sleeve. The sealing sleeve has a through hole connecting the sensing surface of the sensing body and the sensing cavity 125.

[0059] Please see Figure 5 The inner support 12 includes a first support 121 and a second support 122. The first support 121 extends along the axial direction of the atomizing chamber 212 and is disposed in close contact with the inner sidewall of the outer shell 11. The second support 122 is disposed at the end of the first support 121 away from the first cavity 14 (away from the mouthpiece 111) and extends approximately along the axial direction perpendicular to the atomizing chamber 212. The second bracket 122, facing the first cavity 14, cooperates with the first bracket 121 to form a liquid replenishment assembly 30. The side facing away from the first cavity 14 forms the aforementioned sensing channel 126 and sensing cavity 125. The sensing channel 126 includes a main airway 1261 and a negative pressure sensing airway 1262. The main airway 1261 is connected to the airflow channel 151. The negative pressure sensing airway 1262 penetrates the side wall of the main airway 1261 and connects the main airway 1261 and the sensing cavity 125. When air flows into the airflow channel 151 through the main airway 1261, a pressure difference is formed between the main airway 1261 and the sensing cavity 125 at both ends of the negative pressure sensing airway 1262 due to the rapid passage of airflow. The airflow sensor 53 can realize the self-starting of the electronic atomization device 1 based on this pressure difference.

[0060] Please see Figure 6The second support 122 has a first protrusion 123 and a second protrusion 124 on the side facing away from the first cavity 14. The second protrusion 124 is disposed inside the first protrusion 123 and is spaced apart from the first protrusion 123 to form a sensing cavity 125. The second protrusion 124 has a first through hole to form a main air passage 1261. The first through hole extends along the axial direction of the atomizing cavity 212 and passes through the second support 122. The side of the second protrusion 124 has a second through hole to form a negative pressure sensing air passage 1262. The second through hole passes through the second protrusion 124 in a direction approximately perpendicular to the axial direction of the atomizing cavity 212, realizing the connection between the main air passage 1261 and the sensing cavity 125. Since the second through hole is disposed on the side wall of the main air passage 1261 and its size is relatively small, the cavity volume of the airflow sensor 53 can be reduced when sensing, thereby improving its sensing sensitivity and accuracy. The circuit board 52 is arranged roughly parallel to the second bracket 122. The sensing surface of the airflow sensor 53 is also arranged roughly parallel to the second bracket 122 and the circuit board 52 in the sensing cavity 125. The battery 51 is arranged parallel to the circuit board 52, which can reduce the space occupied by the electronic atomizing device 1.

[0061] To reduce resistance during user inhalation, the main airway 1261 and the airflow channel 151 are coaxially arranged, as are the airflow channel 151 and the atomizing chamber 212, with all their axes being straight lines, thereby effectively improving the smoothness of user inhalation.

[0062] Because the pumping mechanism 40 may experience mechanical vibration during operation, which could damage the pumping mechanism 40 or other structures within the electronic atomizing device 1, a shock-absorbing component 46 is provided inside the third chamber 16. This component 46 covers the outside of the pumping mechanism 40 and absorbs and reduces the mechanical vibration generated during operation. The shock-absorbing component 46 can be made of damping cotton. Alternatively, it can be made of springs, silicone, or other materials.

[0063] The pumping mechanism 40 includes an inlet pipe 43, an outlet pipe 45, and a pumping component 44. An inlet end 41 and an outlet end 42 are mounted on the pumping component 44. The inlet pipe 43 connects the inlet end 41 and the replenishment component 30, and the outlet pipe 45 connects the outlet end 42 and the storage chamber 211. The inner support 12 has corresponding mounting holes, allowing the inlet pipe 43 to pass through the mounting holes from the second chamber 15 to the third chamber 16 and connect with the inlet end 41. One end of the outlet pipe 45 connects with the outlet end 42, and the other end passes through the mounting holes from the third chamber 16 to the first chamber 14 and connects with the storage chamber 211. Alternatively, the inlet channel of the storage chamber 211 passes through the mounting holes and connects with the outlet pipe 45 in the third chamber 16. The pumping component 44 can be a peristaltic pump or a piezoelectric ceramic pump, etc. The pumping component 44 is electrically connected to the circuit board 52, and its start-up or shutdown is achieved by triggering the control circuit on the circuit board 52. Please refer to [link to relevant documentation]. Figure 6The first bracket 121 of the inner bracket 12 is provided with a first mounting hole 1211 and a second mounting hole 1212. The first mounting hole 1211 passes through the first bracket 121 along the axial direction of the atomizing chamber 212 to connect the first chamber 14 and the second chamber 15. The second mounting hole 1212 passes through the first bracket 121 along the axial direction of the atomizing chamber 212 to connect the first chamber 14 and the third chamber 16. The liquid inlet pipe 43 passes from the second chamber 15 through the first mounting hole 1211 to the first chamber 14, and then through the second mounting hole 1212 from the first chamber 14 to the third chamber 16 and connects to the liquid inlet end 41. One end of the liquid outlet pipe 44 is connected to the liquid outlet end 42, and the other end is connected to the liquid inlet channel of the liquid storage chamber 211 that passes from the first chamber 14 through the second mounting hole 1212 to the third chamber 16. To prevent the outlet pipe 44 from shaking during the operation of the pumping component 44 and affecting the replenishment effect, the first bracket 121 of the inner bracket 12 is also provided with a fixing structure 1213, on which the outlet pipe 44 is fixed. The fixing structure 1213 can be in the form of a hook (unclosed) or a hanging ring (closed).

[0064] A liquid level meter 54 is provided inside the liquid storage chamber 211. The liquid level meter 54 is electrically connected to the circuit board 52. The circuit board 52 is used to trigger the pumping mechanism 40 to inject liquid into or stop injecting liquid into the liquid storage chamber 211 based on the liquid level information obtained by the liquid level meter 54. By setting the liquid level meter 54, the pumping mechanism 40 can automatically start according to the liquid level in the liquid storage chamber 211, thereby ensuring sufficient atomized matrix in the liquid storage chamber 211. In some embodiments, the circuit board 52 can trigger the pumping mechanism 40 to transfer the atomized matrix when the liquid level information obtained by the liquid level meter 54 is lower than a first liquid level, and trigger the pumping mechanism 40 to stop transferring the atomized matrix when the liquid level information obtained by the liquid level meter 54 is higher than a second liquid level. The liquid level meter 54 can be an electrode needle type liquid level meter 54 or a capacitive liquid level meter 54. When the liquid level meter 54 is an electrode needle type liquid level meter 54, please refer to [further details omitted]. Figure 6 It includes two electrode needles 541. One electrode needle 541 is electrically connected to the circuit board 52, and the other electrode needle 541 extends into the liquid storage chamber 211. When the liquid level in the liquid storage chamber 211 is lower than the electrode needle, the circuit is cut off, the current decreases, the resistance increases, and the circuit board 52 controls the pumping mechanism 40 to start. When the liquid level in the liquid storage chamber 211 is higher than the electrode needle, the circuit is connected, the current increases, and the circuit board 52 controls the pumping mechanism 40 to stop.

[0065] Please see Figure 7 , Figure 8The outer shell 11 of the housing assembly 10 is provided with a first observation window 113, a second observation window 114, and a third observation window 115. The first observation window 113 is correspondingly arranged with the first cavity 14 and is used to observe the liquid level in the liquid storage cavity 211; the second observation window 114 is correspondingly arranged with the second cavity 15 and is used to observe the liquid level in the replenishment assembly 30; the third observation window 115 is correspondingly arranged with the third cavity 16 and is used to observe the working status of the pumping mechanism 40. Through the setting of the first observation window 113, the second observation window 114, and the third observation window 115, the status of each structural component inside the electronic atomizing device 1 can be monitored in real time, so that the user can make timely responses to improve the service life of the electronic atomizing device 1 and ensure the aerosol generation effect. The first observation window 113, the second observation window 114, and the third observation window 115 are set on the outer shell 11 and are integrally formed with the outer shell 11 or designed separately. When designed separately from the outer casing 11, the first observation window 113, the second observation window 114, and the third observation window 115 are made of different materials from the outer casing 11, and the first observation window 113, the second observation window 114, and the third observation window 115 are made of transparent material. The first observation window 113, the second observation window 114, and the third observation window 115 are connected to the outer casing 11 by adhesive, fastening, or other methods. Since the working status of the pumping mechanism 40 can be observed by observing the vibration of the outlet pipe 45, the third observation window 115 should correspond to the setting position of the fixed structure 1213, such as... Figure 7 As shown.
