[0057] The present utility model will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings.

In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0058] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0059] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The terms "connection" and "coupling" used in this application, unless otherwise specified, both include direct and indirect connections (couplings).

[0060] The problem that the assembly efficiency of the control components of the existing products is relatively low.

[0061] In this application, the guiding and limiting of the control components are achieved by the cooperation of the output terminals and the first holes, and the control components and the guiding structures.

[0062] Such as Figures 1 to 6As shown, in one embodiment, an atomizing device is provided, including: a housing 1 having a liquid storage cavity for accommodating an atomizing matrix; an atomizing assembly 4 configured to be in direct liquid conduction communication with the liquid storage cavity or configured to operably establish liquid conduction communication with the liquid storage cavity; a mouthpiece 14 positioned at one end of the housing 1, and an air outlet 141 of the mouthpiece 14 is in air flow communication with the atomizing assembly 4; an air inlet 13 disposed on the housing 1 to form a first air flow path from the air inlet 13 to the air outlet 141; an air flow sensor 33 that generates a first electrical signal in response to suction, and the air flow sensor 33 is in communication with the air outlet 141 to establish a second air flow path from the air outlet 141 to the air flow sensor 33; a power source 38 and a control assembly 3, the control assembly 3 receives the first electrical signal and controls the power source 38 to supply voltage to the atomizing assembly 4 based on the first electrical signal, and the control assembly 3 has a plurality of output terminals 35; a mounting base 2 disposed inside the housing 1, the mounting base 2 has at least one first hole 241 for inserting the output terminals 35 therethrough; the mounting base 2 further has a guiding structure for guiding the movement of the control assembly 3 to align the output terminals 35 with the first holes 241.

[0063] In this embodiment, since the control assembly 3 is provided with output terminals 35 and the mounting base 2 is provided with first holes 241 and a guiding structure. Thus, during the assembly process of the control assembly 3 and the mounting base 2, by guiding the movement of the control assembly 3 through the guiding structure, the output terminals 35 can be aligned with the first holes 241 and the plugging fit can be completed, thereby realizing the installation of the control assembly 3. Moreover, the installation method of the control assembly 3 in the embodiment of the present application is simple and convenient, which is beneficial to improving the assembly efficiency of the atomizing device.

[0064] It should be noted that in the embodiment of the present application, the first direction X refers to the X-axis direction, the second direction Y refers to the Y-axis direction, the third direction Z is the Z-axis direction, and the first direction X, the second direction Y, and the third direction Z intersect pairwise. In one embodiment, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other pairwise. In addition, the embodiment of the present application does not limit the setting numbers of the output terminals 35 and the first holes 241. It can be understood that the output terminals 35 and the first holes 241 need to satisfy the same number and relative positions. In one embodiment, three output terminals 35 are provided, and correspondingly, three first holes 241 are provided, and one output terminal 35 passes through one first hole 241.

[0065] In one embodiment, when the suction causes a change in the air pressure in the second air flow path, the air flow sensor 33 generates a first electrical signal. The control assembly 3 can receive the first electrical signal and control the power supply 38 to supply voltage to the atomization assembly 4, so as to start the atomization assembly 4. At the same time, part of the external atmosphere enters the first air flow path and sends the aerosol generated by the atomization assembly 4 to the air outlet 141 for the user to use.

[0066] In one embodiment, in addition to the first air flow path from the air inlet 13 to the air outlet 141 and the second air flow path from the air outlet 141 to the air flow sensor 33, the atomization device further includes a third air flow path from the air inlet 13 to the air flow sensor 33. Based on this, the working process of the atomization device is generally as follows: when the user sucks, part of the external atmosphere enters the third air flow path. When the air flow passes through the air flow sensor 33, the air flow sensor 33 generates a first electrical signal. The control assembly 3 can receive the first electrical signal and control the power supply 38 to supply voltage to the atomization assembly 4, so as to start the atomization assembly 4.

[0067] In one embodiment, as Figure 3 shown, the first hole 241 has a depth in the insertion direction of the output terminal 35, and the aperture of the first hole 241 gradually decreases from the upstream to the downstream in the insertion direction. That is, the opening shape of the first hole 241 is generally frustum-shaped. Since the output terminal 35 is usually cylindrical, on the one hand, it is convenient for the initial fit of the output terminal 35 and the first hole 241, so as to effectively guide the insertion of the output terminal 35. On the other hand, the trapezoidal cross-section can gradually adapt to the shape of the output terminal 35 during the plugging process, so as to improve the accuracy of the plugging fit. It can be understood that this special frustum shape can play a guiding role and belongs to a part of the guiding structure of the embodiment of the present application.

[0068] In one embodiment, as Figure 5 shown, the guiding structure further includes a limiting member 231. The mounting seat 2 has a side wall 23 that is substantially parallel to the insertion direction of the output terminal 35. At least one limiting member 231 is provided on the side wall 23. The limiting member 231 is used to limit the relative position of the control assembly 3 and the mounting seat 2. In this way, by providing the limiting member 231, during the assembly process of the control assembly 3 and the mounting seat 2, the limiting member 231 can limit the control assembly 3, so as to realize the fixation of the power supply assembly, which is beneficial to improving the connection reliability of the control assembly 3 to the mounting seat 2.

[0069] In one embodiment, there are two limiting members 231, and the two limiting members 231 are arranged at intervals along the third direction Z. In this embodiment, due to the arrangement of the two limiting members 231 spaced apart along the third direction Z, on the one hand, an avoidance space can be formed between the two limiting members 231, so as to avoid other components connected to the control assembly 3. On the other hand, through the abutment of the two limiting members 231 against the control assembly 3, the reliability of guiding and limiting can be improved, and the problem of skew during or after the installation of the control assembly 3 can be avoided.

[0070] In one embodiment, the mounting base 2 has a top wall 24, and the first hole 241 is formed in the top wall 24; the limiting member 231 includes an inclined section 2312 and a straight section 2311 connected to each other, and the straight section 2311 is arranged close to the top wall 24; the inclined section 2312 is used to guide the control assembly 3, and the straight section 2311 abuts against the control assembly 3 to limit the control assembly 3. Specifically, the control assembly 3 includes a first circuit board 31, and the output terminal 35 extends out of the first circuit board 31 along the length direction of the first circuit board 31, that is, the first direction X, and is located on the left side of the first circuit board 31. Among them, the limiting member 231 cooperates with the first circuit board 31.

[0071] In this embodiment, by providing the inclined section 2312, during the process of installing the control assembly 3 onto the mounting base 2, through the control assembly 3, that is, the abutment of the first circuit board 31 against at least part of the inclined section 2312, the first circuit board 31 can be guided to move upward along the first direction X, avoiding skew during the installation of the first circuit board 31. By providing the straight section 2311, when the control assembly 3 is installed in place, the straight section 2311 remains in abutment with the first circuit board 31, that is, through the cooperation of the output terminal 35 located on the left side of the first circuit board 31 and the first hole 241, and the abutment of the limiting member 231 located on the right side of the first circuit board 31 against the first circuit board 31, the first circuit board 31 can be reliably fixed to the mounting base 2.

[0072] It should be noted that the connection between the inclined section 2312 and the straight section 2311 is rounded to make the transition between the inclined section 2312 and the straight section 2311 smooth, which is beneficial to improving the installation stability of the control assembly 3.

[0073] In one embodiment, the mounting base 2 has a top wall 24, the first hole 241 is formed in the top wall 24, the top wall 24 constitutes at least part of the connection interface A, and the output terminal 35 protrudes from or recesses from the connection interface A; the atomization assembly 4 has pins 42, and the pins 42 are electrically connected through the connection interface A and the output terminal 35.

[0074] In this embodiment, through the electrical connection between the output terminal 35 and the pin 42, the control component 3 can control the power supply 38 to supply voltage to the atomization component 4, so that the atomization component 4 can heat and atomize the atomization matrix to generate an aerosol.

[0075] It should be noted that the output terminal 35 includes, but is not limited to, structures with relatively high stiffness and electrical conductivity such as copper posts, aluminum posts, silver posts, gold posts or alloy posts. In this way, on the one hand, due to the relatively high stiffness of the output terminal 35, it can play a role in guiding and limiting the control component 3. On the other hand, due to the electrical conductivity of the output terminal 35, it can be electrically connected to the atomization component 4 to achieve the transmission of electrical energy. In addition, in the embodiment of the present application, the "connection interface A" refers to the contact surface formed between the atomization component 4 and the control component 3 after the atomization device is assembled. In one embodiment, the top wall 24 of the mounting seat 2 and at least part of the housing 1 enclose to form a first accommodation cavity 21. By arranging the atomization component 4 in the first accommodation cavity 21, the installation and fixation of the atomization component 4 can be achieved. In this case, the connection interface A refers to the surface of the top wall 24 on the side close to the atomization component 4.

[0076] In one embodiment, the liquid storage cavity has a lower seal 41, at least part of the lower seal 41 is in contact with the connection interface A; the pin 42 is positioned on the lower seal 41, and the pin 42 is exposed outside the lower seal 41. In this way, by positioning the pin 42 on the lower seal 41, the fixation of the pin 42 can be achieved. By exposing the pin 42 outside the lower seal 41, it is convenient for the pin 42 to be electrically connected to the output terminal 35.

[0077] It should be noted that the liquid storage cavity in the embodiment of the present application refers to the space formed inside the housing 1 for storing the atomization matrix. Specifically, the space formed by the side of the mounting seat 2 close to the mouthpiece 14 and at least part of the housing 1 is the liquid storage cavity. The atomization component 4 is usually arranged in the middle of the liquid storage cavity so that the atomization matrix can enter the atomization component 4.

[0078] Such as Figure 2 and Figure 7As shown, in one embodiment, the lower seal 41 is provided with a second hole 411, at least a part of the second hole 411 is aligned with the first hole 241, and the pin 42 extends into the second hole 411; at least a part of the output terminal 35 is inserted into the second hole 411 to be electrically connected to the pin 42. In this embodiment, since the lower seal 41 is provided with the second hole 411 aligned with the first hole 241 and the pin 42 extends into the second hole 411. In this way, during the process of installing the control component 3 onto the mounting base 2, on the one hand, through the insertion fit between the output terminal 35 and the second hole 411, the control component 3 can be guided and positioned. On the other hand, when the output terminal 35 is inserted into the second hole 411, it can contact the pin 42, thereby realizing the electrical connection between the two. This electrical connection method is simple and convenient, which is beneficial to simplifying the assembly process and further improving the assembly efficiency of the atomizing device. It should be noted that "at least a part of the second hole 411 is aligned with the first hole 241" in the embodiment of the present application means that after the control component 3 and the mounting base 2 are assembled, at least a part of the second hole 411 is aligned with the first hole 241.

[0079] In practical applications, one end of the atomizing component 4 away from the lower seal 41 is hermetically connected to the air outlet 141, and the atomizing airway 43 located inside the atomizing component 4 and extending along the first direction X is communicated with the air outlet 141, and the pin 42 is installed on the inner wall of the atomizing airway 43. The atomizing matrix in the liquid storage cavity enters the inside of the atomizing component 4 from the outside of the atomizing component 4 and is heated by the pin 42 to form an aerosol. Among them, the lower seal 41 has good sealing performance, which can effectively prevent the atomizing matrix in the oil storage cavity from leaking to the control component 3 located in the first installation cavity 11.

[0080] It should be noted that the lower seal 41 is a structure that can undergo elastic deformation. The lower seal 41 includes, but is not limited to, a silicone lower seal 41. In addition, the number of pins 42 is the same as the number of output terminals 35. In one embodiment, three pins 42 are provided. Correspondingly, three output terminals 35 are provided, and one output terminal 35 is electrically connected to one pin 42. The second holes 411 and the output terminals 35 should satisfy the same number and relative positions. In one embodiment, three output terminals 35 are provided. Correspondingly, three second holes 411 are provided, and one output terminal 35 is inserted into one second hole 411. In addition, the size of the second holes 411 can be slightly smaller than the size of the output terminals 35. During the process of inserting the output terminals 35 into the second holes 411, the hole walls of the second holes 411 are deformed by the extrusion of the output terminals 35. In this way, on the one hand, the output terminals 35 can be closely attached to the hole walls of the second holes 411, so that the output terminals 35 and the second holes 411 are reliably inserted together, which is beneficial to improving the limit reliability of the control component 3. On the other hand, the output terminals 35 can be closely attached to the pins 42 located in the second holes 411, which is beneficial to improving the electrical connection reliability between the two.

[0081] In one embodiment, the control component 3 further includes a first circuit board 31. The airflow sensor 33 is disposed on the first circuit board 31. The atomization device further includes a seal 34 that covers the airflow sensor 33. The first circuit board 31 is disposed along the length direction of the atomization device, and the output terminals 35 extend out of the first circuit board 31 along the length direction of the first circuit board 31.

[0082] In this embodiment, by disposing the airflow sensor 33 on the first circuit board 31, not only can the fixation of the airflow sensor 33 be realized, but also it is convenient for the first circuit board 31 to receive the first electrical signal generated by the airflow sensor 33 in a timely manner. By providing the seal 34, while protecting the airflow sensor 33, the airflow sensor 33 can be in a relatively enclosed space, effectively reducing the occurrence of misactivation of the airflow sensor 33. In addition, since the output terminals 35 extend out of the first circuit board 31 along the length direction of the first circuit board 31, it is convenient for the output terminals 35 to be inserted and mated with the first holes 241 and the second holes 411, so as to realize the convenient installation of the first circuit board 31.

[0083] In one embodiment, the mounting base 2 has a side wall 23 that is substantially parallel to the insertion direction of the output terminals 35. The airflow sensor 33 is disposed on one side of the first circuit board 31 close to the side wall 23. In this way, after the control component 3 and the mounting base 2 are assembled, the seal 34 that covers the airflow sensor 33 is pressed between the first circuit board 31 and the side wall 23, thereby improving the sealing effect of the airflow sensor 33 and effectively reducing the occurrence of misactivation of the airflow sensor 33.

[0084] It should be noted that the first circuit board 31 is electrically connected to the air flow sensor 33 to provide voltage for the air flow sensor 33. Among them, the air flow sensor 33 can adopt existing products, and the first circuit board 31 can adopt a printed circuit board (PCB), which has a certain rigidity and can press the seal 34 against the side wall 23 of the mounting seat 2, which is beneficial to improving the sealing performance. In addition, the seal 34 can be connected to the first circuit board 31 by bonding or other connection methods. For example, the first circuit board 31 is provided with two third through holes 312, and the seal 34 is provided with two protruding portions 343 on the side close to the first circuit board 31, and one protruding portion 343 is embedded in one third through hole 312, so as to realize the connection between the first circuit board 31 and the seal 34. In addition, in the embodiment of the present application, the seal 34 includes but is not limited to a silicone seal 34. In addition, as Figure 9 shown, since both the first circuit board 31 and the output terminal 35 extend along the first direction X, in order to connect the output terminal 35 to the first circuit board 31, the end of the output terminal 35 close to the first circuit board 31 is provided with a bent portion, and the first circuit board 31 is provided with a conductive hole, and the bent portion is inserted into the conductive hole, so as to realize the reliable connection between the output terminal 35 and the first circuit board 31.

[0085] As Figure 2 , Figure 10 and Figure 11 shown, in an embodiment, the first circuit board 31 is provided with a first through hole 311, and the first through hole 311 is in air flow communication with the first surface of the air flow sensor 33; the seal 34 is provided with a channel 341, the channel 341 is in air flow communication with the second surface of the air flow sensor 33, and the channel 341 and the air outlet 141 of the suction nozzle 14 are in air flow communication; the first surface and the second surface are arranged opposite to each other.

[0086] In this embodiment, by providing the first through hole 311 on the first circuit board 31, a third air flow path from the air inlet 13 to the first surface of the air flow sensor 33 can be established, that is, the first through hole 311 can connect the first surface of the air flow sensor 33 with the air inlet 13, so that the air flow can be detected in time when the user uses it and a first electrical signal is generated. By providing the channel 341 on the seal 34, a second air flow path from the air outlet 141 to the second surface of the air flow sensor 33 can be established, that is, the channel 341 can connect the second surface of the air flow sensor 33 with the air outlet 141, so that the air pressure change of the second air flow path can be responded to in time when the user uses it and a first electrical signal is generated.

[0087] As Figure 11As shown, in one embodiment, the seal 34 is provided with a second through hole 342 at a corresponding position of the airflow sensor 33, and the second through hole 342 communicates with the channel 341; the airflow sensor 33 is embedded in the second through hole 342 so that the airflow sensor 33 is covered by the seal 34.

[0088] In this embodiment, due to the provision of the second through hole 342 communicating with the channel 341 and the airflow sensor 33 being embedded in the second through hole 342. In this way, on the one hand, when the seal 34 is hermetically connected to the first circuit board 31 and the side wall 23 respectively, the airflow sensor 33 can be in a closed space, thereby protecting the airflow sensor 33 and preventing the airflow sensor 33 from misstarting. On the other hand, since the second through hole 342 communicates with the channel 341, the airflow sensor 33 can promptly respond to the air pressure change in the second airflow path and generate a first electrical signal.

[0089] As Figure 6 and Figure 8 As shown, in one embodiment, the lower seal 41 includes: a mounting hole 412 and a communication hole 413; the mounting hole 412 and the communication hole 413 communicate with each other, and the communication hole 413 is arranged close to the top wall 24; the atomizing assembly 4 is embedded in the mounting hole 412, and the atomizing assembly 4 includes an atomizing air passage 43, and both ends of the atomizing air passage 43 communicate with the air outlet 141 and the communication hole 413 respectively; the mounting base 2 is provided with a first air hole 242 and a second air hole 243, the first air hole 242 is used to communicate the channel 341 with the communication hole 413, and the second air hole 243 is used to communicate the air inlet 13 with the communication hole 413.

[0090] In this embodiment, on the one hand, by embedding the atomizing assembly 4 in the mounting hole 412, a sealed connection between the atomizing assembly 4 and the lower seal 41 can be achieved. On the other hand, by providing the first air hole 242 and the second air hole 243, where the first air hole 242 can communicate the channel 341 with the communication hole 413 to form a connected second airflow path, that is, the detection airway; the second air hole 243 can communicate the air inlet 13 with the communication hole 413 to form a connected first airflow path, that is, the air inlet airway.

[0091] As Figures 4 to 5 As shown, in one embodiment, the mounting base 2 further includes a second receiving cavity 22 for receiving the liquid absorbing member 5, and the liquid absorbing member 5 is used for absorbing liquid. Specifically, the mounting base 2 further includes a bottom wall 25, and the bottom wall 25 and the side wall 23 enclose to form the second receiving cavity 22, and the second receiving cavity 22 communicates with the first receiving cavity 21.

[0092] In this embodiment, on the one hand, due to the provision of the second accommodation cavity 22, the second accommodation cavity 22 communicates with the first accommodation cavity 21, and the atomization component 4 is arranged in the first accommodation cavity 21, and the liquid absorption member 5 is arranged in the second accommodation cavity 22. In this way, during the use of the atomization device, the second accommodation cavity 22 located below can timely absorb the liquid in the atomization component 4, avoiding the liquid from eroding the components upstream of the atomization component 4, such as the airflow sensor 33. In addition, since there is a specifically provided second accommodation cavity 22 for installing the liquid absorption member 5, the volume of the liquid absorption member 5 can be appropriately increased, so that the liquid can be timely absorbed. It should be noted that the liquid includes the leaked atomization matrix (i.e., liquid leakage) and the condensed atomization matrix (i.e., condensate), and among them, the condensate is the main part. In addition, the air inlet 13 of the atomization device is the upstream, and the air outlet 141 is the downstream. In addition, the material of the liquid absorption member 5 includes but is not limited to fiber cotton.

[0093] In one embodiment, the communication hole 413 is located within the projection range of the second accommodation cavity 22 along the first direction X. In this way, the atomization matrix (i.e., condensate) condensed in the atomization airway 43 and the atomization matrix (i.e., liquid leakage) leaking between the mounting hole 412 and the atomization component 4 can directly drip onto the liquid absorption member 5 in the second accommodation cavity 22 through the communication hole 413 and be absorbed, which can effectively reduce the risk of liquid leakage to other components.

[0094] As Figure 7 shown, in one embodiment, a rib 414 is provided on the side of the lower seal 41 close to the top wall 24. The rib 414 is arranged in the circumferential direction of the communication hole 413, and the first air hole 242 and the second air hole 243 are located within the projection range of the rib 414 along the first direction X.

[0095] In practical applications, in order to improve the sealing effect between the lower seal 41 and the mounting seat 2, the lower seal 41 is usually pressed tightly in the first accommodation cavity 21, which will cause the first air hole 242 and the second air hole 243 opened on the top wall 24 to be blocked, which is not conducive to the flow of gas. Based on this, in this embodiment, by providing a rib 414 on the side of the lower seal 41 close to the top wall 24, and the first air hole 242 and the second air hole are located within the projection range of the rib 414 along the first direction X, a space for gas to pass through can be formed between the lower seal 41 and the first air hole 242 and the second air hole, which is conducive to the flow of gas.

[0096] As Figures 9 to 10 shown, in one embodiment, a display screen 36 is provided between the control component 3 and the housing 1; the housing 1 is provided with a visual window (not shown) at the corresponding position of the display screen 36. Specifically, the display screen 36 is arranged on the side of the first circuit board 31 facing away from the airflow sensor 33. In this way, it is convenient for users to observe the power and charge in time, which is conducive to improving the user experience.

[0097] It should be noted that the visible window can be a window opened on the shell 1, that is, the place where the shell 1 corresponds to the display screen 36 is hollowed out; a transparent shell 1 or a partially transparent shell 1 can also be used, so that the display screen 36 can be visible, so that the user can observe the power level and charge in time, which is conducive to improving the user experience.

[0098] like Figure 2 As shown, in one embodiment, the atomization device further includes a frame 37 , which is disposed in the circumference of the display screen 36 and abuts against at least a portion of the housing 1 .

[0099] In this embodiment, by setting a frame 37 around the display screen 36, on the one hand, the display screen 36 can be protected; on the other hand, it can prevent the atomized matrix from condensing on the display screen 36 to form condensate and affect the observation of the power situation. In addition, the abutment between the frame 37 and the shell 1 can also limit the first circuit board 31, so that the first circuit board 31 presses the seal 34. It should be noted that the frame 37 of the embodiment of the present application includes but is not limited to the silicone frame 37, which is elastic and has a good sealing effect when abutting against the shell 1, which can further prevent the atomized matrix from entering between the display screen 36 and the shell 1.

[0100] like Figure 2 and Figure 9 As shown, in one embodiment, the atomization device further includes a first mounting cavity 11 and a second mounting cavity 12, the second mounting cavity 12 and the first mounting cavity 11 are arranged in parallel and are respectively located on both sides of the second accommodating cavity 22, the first circuit board 31 and the airflow sensor 33 are installed in the first mounting cavity 11, and the power supply 38 is installed in the second mounting cavity 12. The control component 3 also includes a second circuit board 32, in the first direction X, the second circuit board 32 is arranged between the housing 1 and the mounting seat 2; the power supply 38 is arranged in the housing 1 and is located on the side of the mounting seat 2 away from the first circuit board 31; the second circuit board 32 is extended along the second direction Y, and the two ends of the second circuit board 32 along the second direction Y are respectively electrically connected to the first circuit board 31 and the power supply 38.

[0101] In this embodiment, by setting up a second circuit board 32, the first circuit board 31 located in the first installation cavity 11 and the power supply 38 of the second installation cavity 12 can be connected together, so that the electric energy of the power supply 38 can be transmitted to the second circuit board 32 and the first circuit board 31 in sequence to power the airflow sensor 33, the atomization assembly 4 and other electrical components.

[0102] It should be noted that the second circuit board 32 can be a printed circuit board (PCB), which has a certain rigidity and can support the power supply 38 and the first circuit board 31 .

[0103] As Figure 9 shown, in one embodiment, the control component 3 further includes a charging interface 39 which is arranged on the side of the second circuit board 32 away from the mounting base 2; an opening is provided at the corresponding position of the housing 1 for the charging interface 39, and the charging interface 39 is embedded in the opening. By providing the charging interface 39, on the one hand, charging of the atomizing device can be achieved, and on the other hand, the gap between the charging interface 39 and the opening can also allow gas to pass through to achieve air intake. It should be noted that when the charging interface 39 is provided, the corresponding power source 38 is a rechargeable power source 38.
