Description

Technical Field

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

[0002] In the current electronic atomization product market, product forms are becoming increasingly diversified, and users' demands for portability and applicability are constantly rising, prompting product design to continuously develop towards miniaturization and compactness. This trend places stricter constraints on the external dimensions of products, while also requiring higher standards for their internal structural layout and space utilization. The miniaturization process often necessitates meticulous structural arrangement within limited space. Such compact structural designs not only need to meet the requirements of functional integration but also need to consider the manufacturability of parts, especially constrained by key processes such as the structural strength of the mold and the feasibility of mold drafting during injection molding.

[0003] In a typical product manufacturing scenario, common electronic atomizing devices generally consist of two main parts: a battery (power supply) and an atomizer. To achieve inhalation sensing control, a microphone (i.e., an airflow sensor) needs to be installed in the device to detect the user's inhalation action and trigger a circuit response. To ensure that the microphone can accurately sense the inhalation signal, an airway (hereinafter referred to as the "microphone airway") connected to the microphone's location must be provided. This microphone airway needs to be connected to the main airway within the atomizer (i.e., the user's inhalation channel), creating a pressure difference before and after the user inhales to trigger a microphone response.

[0004] In practical applications, to reduce the risk of malfunction caused by atomizing liquid leakage to the microphone, a common solution is to place the microphone at the bottom of the entire device, thus keeping it away from the atomizer. This design requires a microphone air passage extending from the area connected to the atomizer to the bottom microphone mounting position inside the battery rod. For the above structure, in the current manufacturing process, this type of microphone air passage is achieved by directly molding it into a slender pipe during battery rod injection molding. The corresponding mold structure requires a slender insert, which is then pulled out after injection molding to form the required air passage. However, this process has two significant drawbacks: (1) Due to the excessive length-to-diameter ratio of the insert structure, its structural strength is significantly insufficient, and it is prone to bending or breaking during repeated mold pulling operations, thus affecting the service life of the mold. (2) To ensure the air passage is formed, this structure requires a material wall thickness around the air passage, resulting in the occupation of internal space, which contradicts the design goals of miniaturization and high integration of the above products. Utility Model Content

[0005] The purpose of this application is to provide an electronic atomizing device to solve the technical problems of insufficient strength of the mold insert and low internal space utilization caused by the process of processing a narrow channel with a microphone at the bottom of the product.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides an electronic atomizing device, comprising: Atomizer; A battery rod includes a bracket and a battery and a main control board mounted on the bracket. The main control board is electrically connected to one end of the battery and has a microphone on it. The bracket has a connector located at the other end of the battery. The connector is used to install and connect with the atomizer. The connector is provided with a connection channel communicating with the main air passage of the atomizer. The outer surface of the bracket is provided with a microphone air passage and a sealing diaphragm. One end of the microphone air passage is connected to the connecting channel, and the other end of the microphone air passage extends to the main control board and is connected to the microphone. The microphone air passage is formed as a through groove on the outer surface of the bracket, and the sealing diaphragm covers the groove of the microphone air passage.

[0007] The beneficial effects of the electronic atomizing device provided in this application are as follows: Compared with the prior art, the electronic atomizing device of this application, for the layout of setting the microphone at the bottom, sets a thin and long through groove on the outer surface of the battery rod as a microphone air passage communicating with the microphone. The solid pipe formed by the traditional process is improved into a surface through groove. Its molding no longer requires a thin and long insert with a high length-to-diameter ratio, which effectively avoids the risk of thin and long inserts being easy to bend and break due to insufficient strength, and is conducive to improving the service life of the mold and the stability of the production process.

[0008] This slotted microphone air passage directly utilizes the outer surface space of the support frame. Simply sealing the slot opening with a diaphragm replaces the original solid wall on one side, effectively reducing the radial or thickness dimensions of the structural components and freeing up internal space, which is beneficial for product miniaturization and compactness. Furthermore, sealing the slot opening with the diaphragm achieves both a thinner profile and ensures the airtightness of the microphone air passage, allowing the microphone to function properly and ensuring accurate sensing of air pressure changes.

[0009] The microphone airway structure on the bracket is improved by providing a recessed groove on the outer surface of the bracket, surrounding the opening of the microphone airway. The sealing diaphragm is embedded in the recessed groove. This utilizes the recessed groove on the outer surface of the bracket to provide a precise mounting and positioning surface for the sealing diaphragm, ensuring that the surface of the sealing diaphragm remains flat with or within a controlled plane of the outer surface of the bracket. This avoids gaps that may occur due to the sealing diaphragm directly covering an uneven surface or due to assembly misalignment, effectively ensuring the airtightness of the microphone airway.

[0010] In one embodiment, the depth of the settling tank is not less than the thickness of the sealing film. This allows the sealing film to be embedded in the settling tank, ensuring that the surface of the sealing film is lower than or flush with the outer surface of the support, effectively reducing the risk of the sealing film being scratched, abraded, or accidentally peeled off during subsequent production processes, transportation, and use.

[0011] In one embodiment, the corners of the sealing film are rounded, and the shape of the groove matches the sealing film. This rounded corner design smoothly disperses externally applied stress, effectively reducing the risk of the sealing film's corners lifting due to friction.

[0012] In one embodiment, the sealing film is attached to the outer surface of the bracket using adhesive. This simplifies the installation process, reduces costs, and effectively ensures a tight seal.

[0013] In one embodiment, the microphone air passage is a straight groove extending along the length of the support, and the shape of the sealing diaphragm is adapted to the microphone air passage and covers the groove opening of the microphone air passage. Thus, the microphone air passage is a straight groove on the outer surface of the support, making the corresponding mold structure simpler, and the strength of the mold structure is much higher than that of the slender inserts used in traditional processes, effectively solving the mold lifespan problem and reducing the mold manufacturing cost.

[0014] In one embodiment, one end of the microphone airway is bent inwards towards the support to form a bend and connect to the connecting channel. The bend in the support has a guide surface, which is either arc-shaped or inclined. This increases the space at the bend between the microphone airway and the connecting channel, provides a smooth transition for airflow, effectively reduces local resistance, and ensures the microphone's sensing sensitivity.

[0015] The structure of the bracket is improved by including a connecting tube inside the bracket for mounting and mates with the microphone, and a through hole within the connecting tube. The through hole connects to the other end of the microphone's air passage, and the microphone is placed inside the connecting tube. In this way, the connecting tube on the bracket provides a precise positioning and accommodating space for the microphone, ensuring that after the microphone is installed, its sensing surface is perfectly aligned with the airflow from the microphone's air passage. This effectively reduces the risk of misalignment due to assembly tolerances, thereby improving the accuracy and consistency of the microphone's signal acquisition.

[0016] In one embodiment, the connecting pipe has a protruding rib connected to the bracket, which abuts against the microphone embedded in the connecting pipe. This provides radial restraint to the microphone, ensuring the sensing surface of the microphone is in the optimal orientation. The fact that the protruding rib is integrally connected to the bracket within the connecting pipe helps improve the structural strength of the connecting pipe.

[0017] The battery rod structure is improved by including a housing. The housing has an air inlet that mates with the atomizer and an air inlet groove on its inner wall. One end of the air inlet groove communicates with the air inlet, and the other end communicates with the connecting channel. This provides a controlled and low-leakage air intake path for the entire atomization system of the electronic atomizing device. This path design ensures that outside air can reliably enter the main airflow channel, a prerequisite for generating the airflow pressure difference detectable by the microphone, thereby ensuring the proper functioning of the device's inhalation triggering function.

Detailed Implementation

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0023] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] To prevent atomizing fluid from leaking into the microphone and causing malfunctions, a common solution is to place the microphone at the bottom of the e-cigarette device (i.e., the bottom of the entire unit), thereby increasing the physical distance between it and the atomizer. This layout requires constructing an airflow channel (i.e., microphone airway) inside the battery holder, extending from the connection area with the atomizer to the microphone mounting position at the bottom of the entire e-cigarette device.

[0026] Regarding the overall layout of the machine described above, in the relevant molding processes, such as Figure 1 As shown, the microphone air passage is typically integrally formed using a slender insert Y in an injection mold. This means the slender pipe structure is directly formed during the injection molding stage of the battery rod, and the air passage is obtained by pulling out the insert Y after the plastic cools. However, this process has certain limitations: Firstly, due to the structural characteristics of the slender air passage, the mold insert Y has a large length-to-diameter ratio, resulting in insufficient structural strength. It is prone to bending or breakage during cyclic extraction, thus affecting the overall lifespan of the mold and production stability. Secondly, to achieve the formation of the air passage, a wall thickness is required in the circumferential direction, which occupies internal space and is detrimental to the miniaturization of the product.

[0027] Therefore, this application provides a novel electronic atomizing device, which improves the microphone airflow structure by constructing the microphone airflow as a through-channel. By reducing the thickness of one side of the solid wall and sealing that side with a sealing film, the airflow is kept airtight while effectively saving internal space. Furthermore, this through-channel structure also changes the mold design, eliminating the need for elongated inserts and avoiding problems such as insufficient mold strength and reduced lifespan caused by excessively large insert aspect ratios. This improves the utilization rate of the product's internal space. A detailed description follows.

[0028] Please refer to the following: Figure 2 and Figure 3 The electronic atomizing device mainly includes an atomizing part and a power supply part. The power supply part is a battery rod 100, and the atomizing part is an atomizer 200. In this embodiment, the atomizer 200 is preferably detachably mounted on the battery rod 100; in other embodiments, the atomizer 200 may also be integrally formed with the battery rod 100. The battery rod 100 mainly houses the power supply components, which are electrically connected to the atomizer 200 to supply power and control the atomizer 200.

[0029] Please refer to the following: Figure 3 , Figure 4 and Figure 5 ( Figure 4 (The arrows in the diagram indicate airflow paths). The battery rod 100 includes a bracket 1 for mounting a power supply component, which includes a battery 2 and a main control board 3, both mounted on the bracket 1. The main control board 3 is electrically connected to one end of the battery 2 and has a microphone 31, which can preferably be a common airflow sensor.

[0030] The bracket 1 has a connector 11 located at the other end of the battery 2. The connector 11 is used for mounting and connecting with the atomizer 200. The connector 11 has a connecting channel 12 that communicates with the main airflow channel of the atomizer 200. The "main airflow channel" here can be understood as the suction airflow channel in the atomizer 200 that connects the mouthpiece and the atomizing coil. When the atomizer 200 is mounted on the connector 11, the suction airflow channel is directly or indirectly connected to the connecting channel 12, so that the air flowing inside the atomizer 200 can flow to the connecting channel 12.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the outer surface of the bracket 1 is provided with a microphone air passage 4 and a sealing diaphragm 5. One end of the microphone air passage 4 is connected to the aforementioned connecting channel 12, and the other end of the microphone air passage 4 extends to the location of the main control board 3 and is connected to the microphone 31. Wherein, as Figure 5As shown, the microphone air passage 4 is formed as a through groove structure on the outer surface of the support 1. This means that a groove is formed on the outer surface of the support 1 that connects to the microphone 31. The groove is a recessed structure with a bottom, two side walls, and two end ports. Then, a sealing film 5 is sealed on the opening of the microphone air passage 4. In this way, while ensuring the formation of the microphone air passage 4, the wall thickness of one side of the passage is reduced, the space occupied is reduced, and the airtightness of the microphone air passage 4 is ensured. Compared with the prior art, the electronic atomizing device provided in this application embodiment, for the layout where the microphone 31 is located at the bottom, has a slender through groove on the outer surface of the battery rod 100 as a microphone air passage 4 communicating with the microphone 31. This improves the traditional "solid pipe" formed by the process into a "surface through groove," eliminating the need for slender inserts with a high aspect ratio in its molding. The corresponding mold structure can adopt, for example... Figure 6 The elongated T-shaped mold X shown is used to form the through groove, which effectively avoids the risks of slender inserts bending or breaking due to insufficient strength, and helps to improve the service life of the mold and the stability of the production process.

[0032] The microphone airway 4, being a slotted design, directly utilizes the outer surface space of the support 1. A sealing film 5 is simply placed over the slot of the microphone airway 4 to replace the original solid wall on one side. This substantially reduces the dimensions of the structural components in the radial or thickness direction, freeing up internal space and facilitating the miniaturization and compactness of electronic atomizing devices. It also provides more space to accommodate larger capacity batteries 2 and other power supply components.

[0033] Furthermore, this structure achieves miniaturization without sacrificing airtightness. By sealing the opening of the microphone airway 4 with a diaphragm 5, both the goal of thinness and lightness is achieved, while reliably ensuring the airtightness of the microphone airway 4, allowing the microphone 31 to function normally and ensuring the accuracy of sensing air pressure changes.

[0034] For the specific structure of the microphone airway 4 on the support 1, please refer to one embodiment of this application. Figure 7 The outer surface of the bracket 1 is also provided with a groove 13 surrounding the groove of the microphone airway 4, and the sealing film 5 is embedded in the groove 13.

[0035] In this embodiment, the bracket 1 can preferably be a frame structure. The interior of the bracket 1 is used to house the power supply components mentioned above. A through-groove type microphone air passage 4 is provided on the outer surface of the bracket 1, and a recessed groove 13 that can accommodate the sealing diaphragm 5 is provided around the groove opening of the microphone air passage 4.

[0036] Therefore, the groove 13 on the outer surface of the bracket 1 provides a precise mounting and positioning surface for the sealing diaphragm 5. When the sealing diaphragm 5 is embedded in the groove 13, the surface of the sealing diaphragm 5 can remain flat with the outer surface of the bracket 1 or be within a controlled plane. This avoids gaps that may occur due to the sealing diaphragm 5 directly covering an uneven surface or due to assembly misalignment. This structure facilitates the firm and uniform fixing of the sealing diaphragm 5 in the groove 13 by means of dispensing, hot melting, or adhesive backing, effectively improving the sealing performance of the microphone airway 4, ensuring that the microphone 31 can accurately sense the inhalation signal, and avoiding malfunctions caused by air leakage.

[0037] In addition, the recessed groove 13 structure also serves to position the sealing film 5 during installation. This ensures more precise and uniform placement of the sealing film 5 during mass production. It helps reduce assembly precision requirements, simplifies installation operations, and ultimately improves production efficiency.

[0038] Preferably, the depth of the sink 13 is not less than the thickness of the sealing film 5, which means that the thickness of the sealing film 5 is less than or equal to the depth of the sink 13 on the outer surface of the support 1.

[0039] In this way, the sealing film 5 is embedded in the groove 13, so that the surface of the sealing film 5 is lower than or flush with the outer surface of the support 1, effectively reducing the risk of the sealing film 5 being directly scratched, abraded or accidentally peeled off during subsequent production processes, transportation and use, improving the protection effect of the sealing film 5, and ensuring the airtightness of the microphone airway 4.

[0040] Regarding the specific structure of the sealing sheet 5, the sealing sheet 5 can preferably be a thin film sheet with a thickness of 0.2-0.3 mm, and particularly preferably a thin film sheet with a thickness of 0.25 mm, which can effectively reduce the wall thickness and reduce the space occupied.

[0041] In practical applications, when the sealing film 5 is subjected to friction or scratches, stress concentration will occur at the corners of the sealing film 5, causing it to easily curl or lift. Once the corners lift, the seal of the sealing film 5 will fail and it will easily fall off.

[0042] Therefore, in one embodiment of this application, please refer to Figure 7 The corners of the sealing film 5 are preferably rounded 51, and the shape of the groove 13 on the outer surface of the bracket 1 matches the shape of the sealing film 5 so that the sealing film 5 can be embedded in the groove 13.

[0043] In this embodiment, the sealing film 5 is preferably a long rectangular sheet, with rounded corners 51 at all four corners. The rounded corners 51 smoothly disperse externally applied stress, effectively reducing the risk of the sealing film 5's edges lifting due to friction. This enhances the structural stability and sealing durability of the sealing film 5 during assembly, transportation, and daily use, thereby ensuring the long-term airtightness of the microphone air passage 4.

[0044] In the embodiments of this application, the sealing film 5 can preferably be fixed to the outer surface of the bracket 1 by adhesive backing, so that the slot of the microphone air passage 4 is within the coverage area of ​​the sealing film 5, effectively ensuring sealing. This allows the microphone 31 to accurately sense changes in air pressure, ensuring trigger sensitivity. In addition, this method of fixing by applying adhesive or using pre-applied adhesive and then pressing is simple to operate, has a fast production cycle, and helps to reduce manufacturing costs.

[0045] In other embodiments, ultrasonic welding or thermo-pressure welding can also be used to fix the sealing film 5 to the outer surface of the bracket 1, which is not specifically limited here.

[0046] For the specific structure of the microphone airway 4, please refer to one embodiment of this application. Figure 7 and Figure 8 The microphone airway 4 is formed as a straight groove extending along the length of the support 1 on the outer surface of the support 1, so that the microphone airway 4 has a straight groove opening on the outer surface of the support 1. Correspondingly, the shape of the sealing diaphragm 5 is adapted to the straight groove opening and covers the straight groove opening, so that the groove opening of the microphone airway 4 is within the coverage area of ​​the sealing diaphragm 5.

[0047] Therefore, the microphone airway 4 is a straight groove on the outer surface of the support 1, which simplifies the corresponding mold structure, such as... Figure 6 The corresponding mold X shown has a structural strength far exceeding that of the slender inserts used in traditional processes, effectively solving the problem of mold lifespan; moreover, the manufacturing cost of mold X is low, and the mold precision is easy to guarantee.

[0048] Furthermore, the regular, straight groove shape of the microphone airway 4, without bends or sharp corners, prevents the sealing film 5 covering it from easily developing wrinkles or internal stress during application, effectively ensuring the uniformity of the adhesive layer thickness. This makes it easier to achieve a complete and tight fit compared to the curved path created by the microphone airway 4.

[0049] In addition, regarding gas flow, the straight channel design of the microphone airway 4, compared to the curved channel, provides less resistance to airflow, lower pressure transmission delay, and less loss. This effectively ensures that the pressure changes generated when the user inhales are transmitted to the microphone 31 at the bottom of the device without attenuation and quickly. This helps to improve the sensitivity and response speed of the microphone 31 to airflow sensing, thereby improving the user experience.

[0050] In one embodiment of this application, please refer to the following: Figure 8 and Figure 9 One end of the microphone airway 4 is bent into the inside of the bracket 1 and connected to the connecting channel 12 on the connecting seat 11. The bent part of the bracket 1 has a guide surface 41, which can preferably be an arc surface or a slope.

[0051] In this embodiment, since one end of the microphone airway 4 needs to be bent and pass through the bracket 1 to connect with the connecting channel 12 on the connecting seat 11, this bend is prone to forming a right angle. When the airflow enters the microphone airway 4 from the connecting channel 12, if it is a right angle turn, it will generate eddies and airflow separation, resulting in increased pressure loss and increased flow resistance.

[0052] Therefore, changing the right-angled section of the bend into a sloping or curved guide surface 41 increases the space at the bend and provides a smooth transition channel for airflow, effectively reducing local resistance. This allows for smoother airflow when the user inhales with the same suction force, and the pressure signal can be transmitted to the microphone 31 more efficiently and accurately, improving the response speed and sensitivity of the airflow sensor, thereby ensuring a better user experience.

[0053] Furthermore, if the bend is a right angle, not only will the airflow be obstructed, but a low-velocity zone will also easily form. If the steam generated during atomization condenses at this point, the condensate will easily accumulate and stagnate in the right-angle corner. Therefore, this embodiment replaces the right-angle bend with a sloping or curved guide surface 41. Using this curved or sloping guide surface 41 eliminates the aforementioned corner where condensate easily accumulates, effectively reducing the risk of airflow blockage or electrical malfunctions caused by condensate, thereby improving the long-term reliability of the product.

[0054] For the structure on bracket 1, please refer to one embodiment of this application. Figure 10 , Figure 11 and Figure 12 The bracket 1 also has a connecting pipe 14 for mounting and engaging with the microphone 31, and a through hole 15 located inside the connecting pipe 14, which is connected to the other end of the microphone air passage 4. The main control board 3 is installed inside the bracket 1, so that the microphone 31 is placed inside the connecting pipe 14.

[0055] In this embodiment, as Figure 10 As shown, the connecting pipe 14 is preferably integrally formed on the inner wall of the bracket 1. The inner wall of the bracket 1 is provided with at least two mounting posts 16 for mounting the main control board 3. Each mounting post 16 has a screw hole, and the two mounting posts 16 are located on opposite sides of the connecting pipe 14. Correspondingly, the main control board 3 is provided with mounting holes 32 that mate with the positions of the mounting posts 16, allowing fasteners such as screws to pass through, thereby forming a symmetrical fixing point structure on both sides. This symmetrical fixing point structure can evenly lock the main control board 3, effectively preventing warping or deformation of the main control board 3 due to single-point force or vibration.

[0056] The microphone 31 on the main control board 3 corresponds to the position of the connecting tube 14, and when the main control board 3 is fixed on the mounting post 16, the microphone 31 can be placed inside the connecting tube 14 to achieve communication with the microphone airway 4.

[0057] Thus, the connecting tube 14 on the bracket 1 provides a precise positioning and housing space for the microphone 31. When the main control board 3 is fixed on the bracket 1, the microphone 31 can be precisely inserted into the connecting tube 14, ensuring that the sensing surface of the microphone 31 is completely aligned with the airflow flowing from the microphone air passage 4, effectively reducing the risk of misalignment caused by assembly tolerances, thereby forming a stable and reliable airflow detection chamber in the connecting tube 14, and thus improving the signal acquisition accuracy and consistency of the microphone 31.

[0058] Based on the above, please refer to the embodiments in this application as well. Figure 11 and Figure 12 The connecting pipe 14 is provided with a protruding rib 141 connected to the bracket 1, and the protruding rib 141 abuts against the microphone 31 embedded in the connecting pipe 14.

[0059] In practical applications, the connecting pipe 14, as a cylindrical structure, typically has a thin wall to save space. In this embodiment, by providing a raised rib 141 integrally connected to the inner wall of the support 1 inside the connecting pipe 14, a strong reinforcing rib is essentially added to the connecting pipe 14. This helps improve the ability of the connecting pipe 14 to resist external extrusion or internal injection molding residual stress, preventing deformation or breakage during production, assembly, or use, thereby improving the structural integrity and long-term reliability of the entire support 1.

[0060] Specifically, in this embodiment, the inner wall of the connecting pipe 14 preferably has at least three evenly distributed ribs 141. These ribs 141 are integrally connected to the inner wall of the support 1, forming a support and limiting structure inside the connecting pipe 14. On the one hand, this helps to ensure that after the microphone 31 is inserted into the connecting pipe 14, its axis is consistent with the axis of the connecting pipe 14, avoiding skewness and ensuring that the sensing surface of the microphone 31 is in the optimal orientation. On the other hand, after the microphone 31 is inserted into the connecting pipe 14, the ribs 141 abut against the microphone 31 to form point contact, thereby achieving a radial limiting effect on the microphone 31.

[0061] The through-holes 15 in the connecting pipe 14 are located between the ribs 141, allowing the airflow entering through the through-holes 15 to smoothly pass through the gaps between the ribs 141 and reach the sensing surface of the microphone 31. This helps to ensure the efficient transmission of the air pressure signal and enables the microphone 31 to function normally.

[0062] For the structure on the battery rod 100, please refer to one embodiment of this application. Figure 13 and Figure 14 (The arrows in the figure indicate the airflow path.) The battery rod 100 also includes a housing 6, and the bracket 1 is housed inside the housing 6. The housing 6 is provided with an air inlet 61 that mates with the atomizer 200 and an air inlet groove 62 located on the inner wall of the housing 6. One end of the air inlet groove 62 is connected to the air inlet 61, and the other end of the air inlet groove 62 is connected to the connecting channel 12.

[0063] In this embodiment, as Figure 14 As shown, a pair of air inlets 61 are symmetrically arranged on both sides of the outer casing 6, and air inlet grooves 62, which communicate with the pair of air inlets 61, are provided on the symmetrical side walls inside the outer casing 6. The air inlet grooves 62 extend to the outer periphery of the connecting seat 11. Correspondingly, symmetrical ventilation notches 111 are provided on the outer periphery of the connecting seat 11, and the ventilation notches 111 communicate with the interior of the connecting seat 11. In this way, a dual-path air intake channel is formed. This dual-path air intake channel can effectively avoid uneven airflow or turbulence that may be caused by single-sided air intake, making the air entering the connecting channel 12 more stable and uniform. Even if one air inlet 61 is accidentally blocked, the other air inlet 61 can still be kept open, which helps to improve the fault tolerance rate.

[0064] Please combine Figure 13 and Figure 14 As shown, when external air enters the interior of the housing 6 through the air inlet 61 on the housing 6, the air will flow along the air inlet groove 62 on the inner wall of the housing 6 to the outer periphery of the connecting seat 11, and enter the interior of the connecting seat 11 through the ventilation notch 111, so that the external air can reach the connecting channel 12 located in the connecting seat 11, and then communicate with the microphone air passage 4 provided on the outer surface of the bracket 1 through the connecting channel 12.

[0065] In this way, the structure provides a controlled and low-leakage air intake path for the entire atomization system on the electronic atomizing device. The design of this path ensures that external air can reliably enter the main air passage, which is a prerequisite for generating an airflow pressure difference that can be detected by the microphone 31, thereby ensuring that the device's suction trigger function works properly.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
