Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to an atomizer and atomization equipment. Background Technology

[0002] Currently, common disposable and refillable atomizing devices typically include an airflow sensor and a corresponding sensing airway. The sensing airway is generally connected to the main airway so that when airflow is generated in the main airway through a suction action, the airflow sensor detects the pressure change and generates a signal. The power supply then controls the power supply to heat and atomize the atomizing matrix, creating an aerosol in the heating chamber that mixes with the airflow in the main airway before flowing out. However, during use, condensate easily accumulates inside the atomizing device (especially on the side of the main airway). If this condensate flows into the sensing airway and comes into contact with the airflow sensor, it can easily cause the sensor to malfunction or be damaged, affecting normal heating and atomization operations and rendering the atomizing device unusable.

[0033] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] 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.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] The atomizer provided in this application changes the connection method between the sensing airway and the main airway in the prior art. It connects the main airway to the sensing airway by opening a side connection port on the side wall. Furthermore, in the first direction, the side connection port is located between the sensing port of the sensing airway and the airflow sensor. This means the airflow between the main airway and the sensing airway needs to follow a bend in its path. This prevents condensate in the main airway from flowing directly into the sensing airway through the sensing port, thus preventing the airflow sensor from malfunctioning or being damaged, when it flows downwards under gravity. The atomizer can be used in atomization equipment and electrically connected to a power supply to electrically heat and atomize the atomization matrix to generate an aerosol.

[0037] The following describes some embodiments of the atomizer and atomizing device provided in this application with reference to the accompanying drawings.

[0038] An embodiment of the first aspect of this application provides an atomizer 100, such as... Figure 1 , Figure 2 , Figure 3As shown, the atomizer 100 includes a housing 1, a heating assembly 2, and an airflow sensor 33. The housing 1 serves as the base of the atomizer 100. One end of the housing 1 in a first direction has an air outlet 131, and at least one end of the housing 1 in a second direction has an air inlet 105. The housing 1 has a main air passage 31 that connects the air inlet 105 and the air outlet 131 for airflow to pass through. The housing 1 also has a liquid storage chamber 101 for storing the atomizing matrix. The heating assembly 2 is disposed in the housing 1 and communicates with the liquid storage chamber 101 so that the atomizing matrix in the liquid storage chamber 101 can enter the heating assembly 2 and be heated and atomized by the heating assembly 2 to generate an aerosol. At least a portion of the structure of the heating assembly 2 extends into the main air passage 31. When the heating assembly 2 heats the atomizing matrix, the generated aerosol can enter the main air passage 31 and flow with the airflow to the air outlet 131. The housing 1 is also provided with a sensing airway 32, which extends along a first direction. In the first direction, the end of the sensing airway 32 near the air outlet 131 has a sensing port 1111, and the end away from the air outlet 131 is connected to an airflow sensor 33. A side connection port 313 is provided on the side wall of the part of the main airway 31 that extends along the first direction. The sensing airway 32 is connected to the main airway 31 through the side connection port 313. When airflow passes through the main airway 31, it can cause a change in the air pressure in the sensing airway 32. The airflow sensor 33 can sense the change in air pressure and generate a corresponding sensing signal, and transmit the sensing signal to the power supply device electrically connected to the airflow sensor 33 to control the heating component 2 to heat the atomizing matrix. In the first direction, the side connection port 313 is located between the sensing port 1111 of the sensing air passage 32 and the airflow sensor 33. When the first direction is the height direction, the height of the sensing port 1111 is higher than that of the side connection port 313, which makes it difficult for the condensate in the main air passage 31 to directly enter the sensing port 1111 during the downward flow, thereby protecting the airflow sensor 33.

[0039] It's understandable that condensation easily forms in the air ducts of common atomizing devices during use. This condensation typically adheres to the air duct walls and flows under gravity. Since the sensing air duct connected to the airflow sensor is usually linked to the main air duct, if there are structural design flaws at this connection, condensation from the main air duct can easily enter the sensing air duct and come into contact with the airflow sensor. This affects the sensor's accuracy and precision, and may even damage the sensor, resulting in ineffective control of the heating element.

[0040] In this embodiment, the atomizer 100, through structural improvements and optimizations, connects the main air passage 31 to the sensing port 1111 via a side connection port 313. An improved connection position design is employed, placing the side connection port 313 between the sensing port 1111 and the airflow sensor 33 in the first direction. When the atomizer 100 is used in an atomizing device, the first direction is the height direction of the atomizing device, and the sensing port 1111 is higher than the side connection port 313. This makes it difficult for condensate adhering to the inner wall of the main air passage 31 to enter the sensing port 1111 when flowing under gravity. This reduces the possibility of condensate in the main air passage 31 contacting the airflow sensor 33 and causing failure or damage, thus preventing disruption to the normal use of the atomizing device and improving the user experience.

[0041] It should be noted that, in practical applications, one or more liquid storage chambers 101 can be set inside the housing 1 according to different usage needs, and the number of heating components 2 corresponds to the number of liquid storage chambers 101. When multiple liquid storage chambers 101 are set, different heating components 2 can heat each liquid storage chamber 101 independently to meet differentiated heating and atomization requirements.

[0042] In this embodiment, the first direction, the second direction, and the third direction can correspond to the height direction, the width direction, and the thickness direction of the atomizing device, respectively, and the same applies to the embodiments below.

[0043] In further embodiments of this application, such as Figure 2 , Figure 3 and Figure 4 As shown, in the atomizer 100, the sensing airway 32 has a first air hole structure 111 at one end facing the air outlet 131 in the first direction. The first air hole structure 111 extends along the first direction, and the outer end of the first air hole structure 111 forms the sensing port 1111 of the sensing airway 32, so that airflow can flow into or out of the sensing airway 32 through the sensing port 1111, so that the airflow sensor 33 can sense the airflow movement through the air pressure change. When the user performs a suction action, a negative pressure is generated in the sensing airway 32. The airflow sensor 33 can sense the airflow movement generated by the suction action and generate a corresponding sensing signal. The power supply device can control the power supply to the heating component 2 according to the sensing signal to heat the atomizing matrix, so that the atomizing matrix is ​​atomized to generate an aerosol.

[0044] In the third direction, the first air hole structure 111 is provided with an arc-shaped guide surface 1112 on the side facing the side connection port 313, and the arc-shaped guide surface 1112 is concave in the direction away from the side connection port 313, so as to guide the gas flowing between the sensing port 1111 and the side connection port 313, so that the airflow can change its flow direction more smoothly, and then enter the main air channel 31 from the side connection port 313, so as to prevent airflow disturbance and impact.

[0045] Furthermore, in a specific implementation, such as Figure 3 , Figure 4 In the example, a first liquid storage space 321 is formed between the circumferential outer wall of the first pore structure 111 and the inner wall of the shell 1. That is, the sensing port 1111 of the first pore structure 111 protrudes outward in the first direction, higher than the horizontal reference plane of the circumferential outer side, to form a surrounding bone structure. When condensate appears outside the sensing port 1111, the condensate will usually flow into the first liquid storage space 321 under the action of gravity. At this time, the height of the sensing port 1111 is relatively high, and the condensate is difficult to directly enter the sensing air passage 32 through the sensing port 1111, thereby further enhancing the protection effect on the sensing air passage 32 and the airflow sensor 33.

[0046] Furthermore, in a specific implementation, such as Figure 3 In the example, in the first direction, the inner diameter of the first vent structure 111 gradually decreases from the inside to the outside. That is, in the direction along the first direction near the air outlet 131, the inner diameter of the first vent structure 111 gradually contracts, forming a funnel-like structure. When a negative pressure is formed at the sensing port 1111, the airflow in the sensing airway 32 flows out from the sensing port 1111 under the action of the negative pressure. Since the inner diameter of the first vent structure 111 gradually decreases, the airflow velocity increases during the process of passing through the first vent structure 111, which enables the airflow to flow out quickly and causes a rapid change in the air pressure in the sensing airway 32. The airflow sensor 33 can detect the air pressure change in time, thereby improving the response speed of the airflow sensor 33. When the user performs a suction action, the heating component 2 can achieve rapid heating and rapid generation of aerosol.

[0047] In further embodiments of this application, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in the atomizer 100, the sensing airway 32 also has a second air pore structure 121. The second air pore structure 121 is located at the end of the sensing airway 32 near the airflow sensor 33 and extends along the first direction. One end of the second air pore structure 121 is correspondingly arranged with the airflow sensor 33 so that the airflow sensor 33 can communicate with the interior of the sensing airway 32 to sense changes in airflow. A second liquid storage space 322 is formed between the circumferential outer wall of the end of the second air pore structure 121 away from the airflow sensor 33 and the inner wall of the sensing airway 32. For example... Figure 3 and Figure 5 As shown, the second vent structure 121 protrudes upward along the first direction, meaning that the top of the second vent structure 121 is higher than the horizontal reference plane on the outer circumferential side, forming a surrounding bone structure. When condensate appears in the sensing airway 32, the condensate flows downward along the inner wall of the sensing airway 32 to the second liquid storage space 322 under the action of gravity. At this time, the port of the second vent structure 121 is relatively high, making it difficult for the condensate to directly enter the second vent structure 121, thereby further preventing the condensate from contacting the airflow sensor 33.

[0048] It is understood that, under normal circumstances, the side connection port 313 and the first vent structure 111 in the aforementioned embodiments can effectively block most of the condensate. However, since the atomizing device is usually placed in a pocket or other location by the user when not in use, it is difficult to avoid tilting or flipping, which may cause a small amount of condensate to enter the sensing air passage 32. The triple protection effect formed by the side connection port 313, the first vent structure 111, and the second vent structure 121 in this embodiment can further increase the difficulty of condensate contacting the airflow sensor 33, reduce the possibility of airflow sensor 33 malfunctioning, and thus extend its service life.

[0049] In further embodiments of this application, such as Figure 2 , Figure 3 and Figure 4As shown, the main airway 31 of the atomizer 100 includes an intake airway 311 and an outlet airway 312. One end of the intake airway 311 is connected to the intake port 105 and extends along the second direction; one end of the outlet airway 312 is connected to the outlet port 131 and extends along the first direction; the end of the intake airway 311 far from the intake port 105 is connected to the end of the outlet airway 312 far from the outlet port 131, forming a bent main airway 31. After the air flow flows into the intake airway 311 from the intake port 105, it first flows along the second direction, and then enters the outlet airway 312 and flows along the first direction. Among them, a gas guiding structure 124 is provided at the connection between the intake airway 311 and the outlet airway 312, and at least part of the structure of the gas guiding structure 124 bulges towards the main airway 31 to form a guiding effect on the air flow, so that the air flow in the intake airway 311 can turn more gently under the guidance of the gas guiding structure 124 and enter the outlet airway 312.

[0050] Further, as shown in Figure 2 , Figure 5 and Figure 7 In the example of the atomizer 100, a gas guiding structure 124 is provided on the inner wall of the intake airway 311 on the side far from the outlet port 131 in the first direction, so that there is a certain distance between the gas guiding structure 124 and the outlet airway 312 in the first direction to reserve space for the air flow to pass through. Among them, in the second direction, the side of the gas guiding structure 124 facing the intake port 105 has a first inclined surface structure 1241, and the first inclined surface structure 1241 is inclined relative to the second direction and forms a first inclination angle a1, where 0° < a1 ≤ 45°. For example, Figure 7 the state shown in

[0051] That is, the first inclined surface structure 1241 is inclined upward relative to the second direction to utilize the upward guiding effect of the first inclined surface structure 1241 on the intake air flow. Due to the angle setting of the first inclined surface structure 1241, which is in a gradually upwardly bulging form, it can guide the air flow to change the flow direction more gently and enter the outlet airway 312.

[0051] Further, in a specific example, as shown in Figure 2 , Figure 5 and Figure 7 In the first direction, a second inclined surface structure 125 is provided on the inner wall of the intake airway 311 on the side far from the outlet port 131, and in the second direction, the second inclined surface structure 125 is located between the intake port 105 and the gas guiding structure 124; the second inclined surface structure 125 is inclined relative to the second direction and forms a second inclination angle a2, and -15° ≤ a2 < 0°. As shown in Figure 7As shown in the figure, in the direction along the second direction close to the air guide structure 124, the second inclined structure 125 gradually tilts downward to increase the flow area of ​​the region corresponding to the second inclined structure 125 in the intake air passage 311. This causes the airflow velocity to slow down first after entering the intake air passage 311, and then enter the exhaust air passage 312 through the guiding effect of the air guide structure 124, thereby reducing the impact when in contact with the air guide structure 124 and the airflow disturbance when turning.

[0052] Among them, such as Figure 7 In the example, in the second direction, the connection between the second inclined structure 125 and the first inclined structure 1241 has a smooth transition surface 1251, so that the airflow can smoothly contact the first inclined structure 1241 through the guiding effect of the smooth transition surface 1251 during the flow of the airflow along the second inclined structure 125, and then turn towards the air outlet duct 312 under the guiding direction of the first inclined structure 1241.

[0053] In addition, such as Figure 7 In the example, the air guide structure 124 has an arc surface 1242 at one end facing the air outlet 312 in the first direction, that is, the top end of the air guide structure 124 forms an arc surface 1242 to further enhance the smoothness of airflow.

[0054] In a specific example, such as Figure 2 and Figure 7 In the example, when the air guide structure 124 has air inlet channels 311 on both sides in the second direction, the air guide structure 124 can adopt a symmetrical structure so as to guide the airflow on both sides at the same time, so that the airflow on both sides can be guided by the air guide structure 124 and flow into the air outlet channel 312 more smoothly, and reduce airflow disturbance.

[0055] Furthermore, such as Figure 3 In the example, the liquid storage chamber 101 is correspondingly arranged with the air inlet channel 311, and at least a portion of the heating component 2 extends into the corresponding air inlet channel 311, so that the aerosol formed by the heating component 2 heating and atomizing the atomizing matrix can enter the air inlet channel 311 and enter the air outlet channel 312 under the drive of the airflow. When the air guide structure 124 has air inlets 311 on both sides in the second direction, each air inlet channel 311 has a liquid storage chamber 101 on the side facing the air outlet 131, and each liquid storage chamber 101 has a heating component 2 at one end near the corresponding air inlet channel 311. This allows for independent heating of the atomizing matrix in each liquid storage chamber 101 according to usage needs, forming grouped or segmented heating to meet the needs of different stages during use.

[0056] In further embodiments of this application, such as Figure 2 , Figure 4 as well as Figure 8 , Figure 9 As shown, the housing 1 of the atomizer 100 specifically includes a middle shell 10, a first sealing element 11, a second sealing element 12, and a mouthpiece structure 13. The middle shell 10 serves as the main body of the housing 1. Both ends of the middle shell 10 in the first direction are open structures, forming a first open end 103 and a second open end 104, respectively. Inside the middle shell 10, a liquid storage chamber 101 and a main air passage 31 tube 102 extending along the first direction are formed. In the second direction, at least one end of the middle shell 10 has an air inlet 105, and the air inlet 105 corresponds to the end of the liquid storage chamber 101 near the second open end. Figure 2 , Figure 4 and Figure 10 As shown, the first sealing member 11 is connected to the first opening end 103 of the middle shell 10, and the second sealing member 12 is connected to the second opening end 104 of the middle shell 10. The first sealing member 11 is sealed to the inner wall of the middle shell 10, and the first sealing member 11 has a first connecting hole 1113, which extends along a first direction and is connected to the main air passage 31 tube 102 of the middle shell 10; the suction nozzle structure 13 is connected to the end of the first sealing member 11 away from the middle shell 10, and at least a portion of the suction nozzle structure 13 extends into the first connecting hole 1113 to form an air outlet passage 312 in sequence with the first connecting hole 1113 and the main air passage 31 tube 102. The end of the suction nozzle structure 13 away from the first connecting hole 1113 forms an air outlet 131; wherein, the end of the suction nozzle structure 13 extending into the first connecting hole 1113 forms a side connecting opening 313 between the end of the suction nozzle structure 13 extending into the first connecting hole 1113 and the inner wall of the first connecting hole 1113 to communicate with the sensing air passage 32. Figures 2 to 7 As shown, the second sealing member 12 is sealed to the inner wall of the middle shell 10. In the first direction, the second sealing member 12 has a gas guide groove 123 at one end facing the liquid storage cavity. The gas guide groove 123 extends along the second direction and forms an air inlet channel 311. One end of the gas guide groove 123 corresponds to the air inlet 105 of the middle shell 10. The other end of the gas guide groove 123 extends to a position corresponding to the air outlet channel 312. The gas guide structure 124 is located on the bottom wall of the gas guide groove 123 at a position corresponding to the air outlet channel 312.

[0057] In further embodiments of this application, such as Figures 2 to 7As shown, a sensing airway tube 106 is also formed inside the middle shell 10. In the third direction, at least one side of the main airway 31 tube 102 has a sensing airway tube 106, which extends along the first direction. Correspondingly, the first sealing member 11 has a first vent structure 111 at the position corresponding to the sensing airway tube 106, with one end of the first vent structure 111 extending into the sensing airway tube 106. The second sealing member 12 has a second vent structure 121 at the position corresponding to the sensing airway tube 106, with one end of the second vent structure 121 extending into the sensing airway tube 106. The sensing airway 32 is formed by sequentially connecting the first vent structure 111, the sensing airway tube 106, and the second vent structure 121. The first air hole structure 111 forms a sensing port 1111 at one end outside the sensing airway tube 106. The second sealing member 12 has a sensor mounting groove 122 at one end of the second air hole structure 121 away from the sensing airway tube 106. The airflow sensor 33 is disposed in the sensor mounting groove 122.

[0058] Specifically, such as Figure 2 and Figure 3 In the example, the suction nozzle structure 13 has an air outlet pipe 132 extending in a first direction and communicating with the air outlet 131. The air outlet pipe 132 extends into the first connecting hole 1113. Correspondingly, at least one side wall of the first connecting hole 1113 is recessed outward in the third direction, and the recess is located outside the first air hole structure 111. The outwardly recessed area on the side wall of the first connecting hole 1113 and the air outlet pipe 132 form a side connecting port 313 in the first direction, so that the sensing port 1111 of the first air hole structure 111 communicates with the first connecting hole 1113 through the side connecting port 313, thereby enabling the sensing air passage 32 to communicate with the main air passage 31.

[0059] In one specific example, such as Figure 3 In the example shown, the main air passage 31 tube 102 inside the middle shell 10 is provided with sensing air passage tubes 106 on both sides in the third direction. Correspondingly, the first sealing member 11 is also provided with a first air hole structure 111 on both sides of the first connecting hole 1113, and the second sealing member 12 is provided with a second air hole structure 121 and a sensor mounting groove 122 on one side of the air guiding structure 124. During the assembly process, the first sealing member 11, the middle shell 10, and the second sealing member 12 can be interchanged in the third direction to complete the assembly connection of the sensing air passage 32 without the need for positioning or identification, which helps to reduce the difficulty of the assembly operation and improve the efficiency of the assembly operation.

[0060] An embodiment of the second aspect of this application provides an atomizing device 500, such as... Figure 11 , Figure 12 , Figure 13As shown, the atomizing device 500 includes a main housing 510, an atomizer 100 as described in any of the embodiments of the first aspect, and a power supply device 520. The main housing 510 serves as a mounting carrier, and an assembly port 511 is provided at one end in the first direction. Part of the atomizer 100 is disposed inside the main housing 510 and corresponds to the assembly port 511. The air outlet 131 of the atomizer 100 is located outside the assembly port 511 for the user to perform inhalation operations. The power supply device 520 is disposed inside the main housing 510 and is electrically connected to the heating component 2 of the atomizer 100 to supply power to the heating component 2, so that the heating component 2 heats up when energized, thereby heating and atomizing the atomizing matrix to generate an aerosol.

[0061] The following describes a specific example of the atomizing device 500 of this application with reference to the accompanying drawings.

[0062] like Figures 1 to 13 As shown, the atomizing device 500 is specifically a liquid storage device. The main housing 510 of the atomizing device 500 has a split assembly structure. The top of the main housing 510 in the first direction has an assembly port 511. The two side walls of the main housing 510 in the third direction are provided with partial hollow structures, allowing external gas to flow into the main housing 510 through the hollow structures. The atomizer 100 is located inside the main housing 510 near the assembly port 511, and the mouthpiece structure 13 of the atomizer 100 extends outward from the assembly port 511. The power supply device 520 is located below the atomizer 100 to supply power to the heating component 2 of the atomizer 100. The main housing 510 has a corresponding support structure 512 for supporting and fixing the atomizer 100 and the power supply device 520.

[0063] like Figures 1 to 4 as well as Figure 12 , Figure 13As shown, the housing 1 of the atomizer 100 includes a main air passage 31 tube 102 located near the center inside the middle shell 10; in the second direction, a liquid storage chamber 101 is provided on each side of the main air passage 31 tube 102; in the third direction, a sensing air passage tube 106 is provided on each side of the main air passage 31 tube 102. Each liquid storage chamber 101 has a slot at its bottom, within which a heating component 2 is installed. The heating component 2 uses a ceramic heating element and is covered with a sealing silicone structure on its outer circumference for a sealed connection with the slot. The second sealing element 12 of the atomizer 100 has a conductive hole 1261 in the area corresponding to the heating component 2. An electrode 1262 is installed in the conductive hole 1261. The ceramic heating element of the heating component 2 is connected to the electrode 1262 via a pin structure and is electrically connected to the power supply device 520 via the electrode 1262. The liquid storage chamber 101 communicates with the slot, allowing the atomizing matrix within the liquid storage chamber 101 to enter the heating component 2. The ceramic heating element heats up when energized, causing the atomizing matrix to atomize and generate an aerosol. The two heating components 2 can be heated individually, simultaneously, or in stages, depending on usage requirements.

[0064] The first seal 11 and the second seal 12 of the atomizer 100 are both made of silicone. The first seal 11 is located at the first opening end 103 of the middle shell 10, and a portion of the first seal 11 extends into the middle shell 10. The circumferential sidewall of the first seal 11 has a sealing ridge to form a sealing fit with the inner sidewall of the middle shell 10. The second seal 12 is located at the second opening end 104 of the middle shell 10, and a portion of the second seal 12 extends into the middle shell 10. The circumferential sidewall of the second seal 12 has a sealing ridge to form a sealing fit with the inner sidewall of the middle shell 10. Two air guide grooves 123 are provided at one end of the second seal 12 facing the air outlet 131. Both air guide grooves 123 extend along the second direction and form an upwardly raised air guide structure 124 at the middle position corresponding to the main air passage 31 pipe body 102. The two air guide grooves 123 correspond to the heating components 2, i.e., the liquid storage chambers 101 on both sides of the main air passage 31 pipe body 102, and together form an air inlet passage 311. The air inlet passage 311 is connected to the air inlet 105 on the side wall of the middle shell 10.

[0065] A first connecting hole 1113 extending along a first direction is provided near the center of the first sealing member 11. The suction nozzle structure 13 is connected to the end of the first sealing member 11 away from the middle shell 10. The two ends of the first connecting hole 1113 are respectively connected to the main air passage 31 tube body 102 and the air outlet pipe 132 of the suction nozzle structure 13 to form an air outlet passage 312. The outer port of the suction nozzle forms an air outlet 131. The two air inlets 311 merge into the air outlet passage 312 at the air guide structure 124 and connect to form a main air passage 31 that is similar to an inverted Y shape.

[0066] Among them, the air guiding structure 124 forms a first inclined surface structure 1241 on both sides in the second direction. The first inclined surface structure 1241 slopes upward and forms a first inclination angle a1 (0° < a1 ≤ 45°); a second inclined surface structure 125 is formed in the area corresponding to the heating component 2 on the bottom wall of the air guiding groove 123. The second inclined surface structure 125 slopes downward and forms a second inclination angle a2 (-15° ≤ a2 < 0°). A smooth transition surface 1251 is formed at the connection between the second inclined surface structure 125 and the first inclined surface structure 1241, and an arc surface 1242 is formed at the top of the air guiding structure 124, so that the airflow in the intake air passage 311 can turn more smoothly and flow into the outlet air passage 312.

[0067] As Figures 3 to 7 shown, both side walls of the first communication hole 1113 on both sides in the third direction have regions recessed outward. The air outlet pipe 132 of the nozzle structure 13 extends into the first communication hole 1113 and forms side communication ports 313 with the side walls of the first communication hole 1113 on both sides in the third direction respectively.

[0068] Correspondingly, on the first seal 11, a first air hole structure 111 is provided on each side of the first communication hole 1113 in the third direction. One end of the first air hole structure 111 extends into the induction air passage tube body 106, and the other end protrudes upward, and a first liquid storage space 321 is formed between the other end and the side wall of the induction air passage tube body 106. And in the first direction, the inner diameter of the first air hole structure 111 gradually decreases from bottom to top; a second air hole structure 121 is provided at a position corresponding to the bottom of one of the induction air passage tube bodies 106 on the second seal 12. One end of the second air hole structure 121 extends into the induction air passage tube body 106, and a second liquid storage space 322 is formed between the circumferential outer wall of the second air hole structure 121 and the inner wall of the induction air passage tube body 106. On the second seal 12, an induction cavity mounting groove is connected to the outer end of the second air hole structure 121, and the airflow sensor 33 is hermetically arranged in the sensor mounting groove 122. In the first direction, the side communication port 313 is located between the induction port 1111 of the first air hole structure 111 and the airflow sensor 33, so that a bent structure similar to an S shape is formed at the connection between the induction air passage 32 and the main air passage 31; at the same time, the recessed part of the side wall of the first communication hole 1113 outward in the third direction extends to the side of the first air hole structure 111 facing the side communication port 313 and forms an arc-shaped guiding surface 1112.

[0069] As Figure 12 and Figure 13As shown, the power supply device 520 includes a battery 521 and an electronic control board 522; the electronic control board 522 is located on the side of the battery 521, and a control circuit is provided on the electronic control board 522. The electronic control board 522 is electrically connected to the battery 521 and the airflow sensor 33, and is electrically connected to the ceramic heating element of the heating assembly 2 through the electrode 1262 on the second sealing member 12.

[0070] During use, when the user performs a suction action through the nozzle structure 13, the airflow in the main airway 31 flows towards the outlet 131, and the sensing port 1111 of the sensing airway 32 generates negative pressure, causing the airflow sensor 33 to sense the change in air pressure within the sensing airway 32 and generate a corresponding sensing signal. The electronic control board 522 receives the sensing signal and controls the battery 521 to supply power to the ceramic heating element of the heating component 2. The ceramic heating element heats up when energized, causing the atomizing matrix to be heated and atomized to generate an aerosol. The airflow flowing into the inlet airway 311 from the inlet 105 mixes with the aerosol and, under the guidance of the air guide structure 124, flows into the outlet airway 312 and is then discharged from the outlet 131 of the nozzle structure 13.

[0071] In practical applications, other auxiliary structures can be set in the atomizing device 500 according to usage needs. For example, an operation button can be set on the end of the main housing 510 opposite to the assembly port 511. The operation button is electrically connected to the electronic control board 522 so that the user can perform corresponding control operations through the operation button. In addition, a corresponding protective sleeve structure can be configured on the mouthpiece structure 13 so that when not in use, the protective sleeve structure can be fitted onto the air outlet 131 end of the mouthpiece structure 13 for dust prevention, leakage prevention and other functions.

[0072] The atomizing device 500 in this embodiment forms multiple protective effects by setting a side connection port 313, a first air hole structure 111, and a second air hole structure 121. This makes it difficult for condensate adhering to the inner wall of the main air channel 31 to enter the sensing air channel 32 and come into contact with the airflow sensor 33, thereby reducing the possibility of airflow sensor 33 malfunctioning, which helps to extend its service life and improve the user experience. In addition, by setting two liquid storage chambers 101 and two heating components 2 in this embodiment, corresponding control operations can be performed as needed during use to achieve heating of any one heating component 2 individually, or heating of both heating components 2 simultaneously. Segmented heating can also be achieved by the cooperation of the two heating components 2 to meet the heating requirements of different stages in the suction process.

[0073] Furthermore, the atomizing device 500 in this embodiment also has all the beneficial effects of the atomizer 100 in any of the above embodiments, which will not be repeated here.

[0074] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
