DETAILED DESCRIPTION

[0032] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and 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.

[0033] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0034] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0035] The electronic atomizer usually mainly includes a heating structure and a power supply structure, wherein the heating structure is used to heat and atomize the substrate to be atomized, and the power supply structure is used to provide power and control to the heating structure. The heating structure includes a nozzle, a substrate to be atomized, and an atomizing component, etc. The atomizing component is used to heat and atomize the substrate to be atomized to generate atomized gas for the user to inhale. As the user inhales, the atomized gas flows through the airway in the nozzle to the user's mouth for inhalation. Due to the path and speed of the atomized gas flow and the rhythm of the user's inhalation, the atomized gas generated by the heating structure may not be able to be discharged from the nozzle in time for the user to inhale. Some of the atomized gas will condense on the side wall of the airway in the nozzle to form condensate. If the condensate formed on the side wall of the nozzle airway is not handled in time, the condensate will accumulate, so that the user will inhale the condensate during subsequent inhalation, affecting the user's inhalation experience. Alternatively, when there is enough condensate on the side wall of the nozzle airway, it is easy to flow out onto the surface of the shell, thereby causing contamination to the user's hands, mouth, and even clothes, affecting the user's experience.

[0036] In order to clean the condensate in the suction nozzle, the present application designs a vibrating member 30 and a powder producing member 20 in the heating structure. The vibrating member 30 enables the powder producing member 20 to produce floating powder. When the user sucks the suction nozzle 40, the floating powder will absorb the condensate and flow to the outside of the suction nozzle 40. The technical solution for cleaning the condensate in the suction nozzle 40 is specifically described as follows:

[0037] See also Figure 1-Figure 7 In one embodiment of the present application, a heating structure is provided, including: a powder storage part 10, a support tube 13, a powder production part 20, a vibrating part 30 and a suction nozzle 40.

[0038] The powder storage member 10 has a hollow chamber, and the powder storage member 10 is used to be connected to the liquid storage bin 70 .

[0039] The support tube 13 is arranged in the hollow chamber. The powder storage member 10 and the outer wall of the support tube 13 enclose a vibration chamber. A plurality of powder outlet holes 131 are provided on the support tube 13. The vibration chamber is connected with the chamber in the support tube 13 through the powder outlet holes 131.

[0040] The powder producing member 20 and the vibrating member 30 are both disposed in the vibration chamber, and the vibrating member 30 is used to vibrate the powder producing member 20 to produce powder floating in the vibration chamber.

[0041] The suction nozzle 40 is located at a side of the powder storage member 10 away from the liquid storage bin 70. An air outlet pipe 41 is provided in the suction nozzle 40. The air outlet pipe 41 is connected to the outside. Both ends of the support pipe 13 are respectively connected to the air outlet pipe 41 and the liquid storage bin 70. An air outlet passage is formed in the air outlet pipe 41, and condensate is formed in the air outlet passage. The air outlet passage in the air outlet pipe 41 here corresponds to the air passage in the suction nozzle 40 mentioned above.

[0042] The powder floating in the vibration chamber is used to flow to the air outlet pipe 41 through the powder outlet hole 131 under the action of suction (for example, the suction generated when the user sucks on the suction nozzle 40), and absorb the condensate on the inner wall of the air outlet pipe 41. The powder containing the condensate can continue to flow out of the suction nozzle 40 under the action of suction.

[0043] The heating structure in the above embodiment is adopted, and a powder producing part 20 and a vibrating part 30 are arranged in the vibration chamber in the powder storage part 10. The vibrating part 30 can vibrate to make the powder producing part 20 produce powder floating in the vibration chamber. An air outlet passage is formed in the air outlet pipe 41, and the vibration chamber and the air outlet passage are connected through the powder outlet hole 131 on the support tube 13 and the support tube 13. In this way, when the user sucks the suction nozzle 40, the powder floating in the vibration chamber can pass through the powder outlet hole 131, the support tube 13, and the air outlet pipe 41 in sequence. The powder flowing to the air outlet pipe 41 can absorb the condensed liquid on the inner wall of the air outlet pipe 41, and flow to the user's mouth together with the atomized gas along with the user's suction action, thereby achieving the purpose of cleaning the condensed liquid in the air outlet pipe 41 (or the suction nozzle 40).

[0044] See also Figure 4 Specifically, the diameter of the powder outlet hole 131 is 0.2 mm-0.3 mm, and / or, a plurality of powder outlet holes 131 are arranged in an array around the axis of the support tube 13 to form a circle of powder outlet holes 131, and along the axial direction of the support tube 13, a plurality of circles of powder outlet holes 131 are distributed on the support tube 13.

[0045] The setting of the powder outlet hole 131 on the support tube 13 is to facilitate the powder floating in the vibration chamber to flow out of the vibration chamber. Therefore, the aperture of the powder outlet hole 131, first of all, needs to ensure that the powder can pass through the powder outlet hole 131 to avoid the occurrence of hole blockage. Secondly, the aperture of the powder outlet hole 131 cannot be too large to avoid too much powder flowing out at one time when the suction nozzle 40 is sucked. On the one hand, part of the powder does not absorb the condensate. On the other hand, too much powder outflow will affect the user's suction experience, or, in the gap between the user's suction (that is, when not sucking), the powder falls to the side away from the suction nozzle 40, for example, falls into the liquid storage tank 70. Based on this, the present application sets the aperture of the powder outlet hole 131 to 0.2mm-0.3mm, so as to better play the effect of powder adsorbing condensate.

[0046] A plurality of powder outlet holes 131 are arranged in an array around the axis of the support tube 13 to form a circle of powder outlet holes 131, and along the axial direction of the support tube 13, a plurality of circles of powder outlet holes 131 are distributed on the support tube 13, that is, a plurality of powder outlet holes 131 are evenly distributed on the entire tube wall of the support tube 13, leaving sufficient channels for the powder in the vibration chamber, so that the powder can flow from any position of the side wall (circumferential or axial) of the support tube 13 into the support tube 13, thereby facilitating the adsorption of the condensate on the entire inner wall of the air outlet pipe 41.

[0047] Preferably, the distribution of the plurality of powder outlet holes 131 on the support tube 13 can be further optimized according to the density of the floating powder distribution in the vibration chamber. Figure 1 For example, at this time, the heating structure is placed vertically, and when the vibrating member 30 is working, the powder producing member 20 produces powder floating in the vibration chamber. Due to gravity, the number or density of the floating powder will continue to decrease from the side close to the vibrating member 30 to the side away from the vibrating member 30. Correspondingly, from the side away from the suction nozzle 40 to the side close to the suction nozzle 40, the number of the same circle of powder outlet holes 131 on the support tube 13 decreases. For example, 6 circles of powder outlet holes 131 are formed on the support tube 13, which is relatively close to the side of the suction nozzle 40. The number of powder holes 131 in each circle on the side close to the suction nozzle 40 is the same, and the number of powder holes 131 in each circle on the side far from the suction nozzle 40 is also the same, but the number of powder holes 131 in the three circles close to the suction nozzle 40 is less than the number of powder holes 131 in the three circles far from the suction nozzle 40, or, the number of powder holes 131 in each circle of the six circles decreases continuously from the side far from the suction nozzle 40 to the side close to the suction nozzle 40. The layout of the multiple powder holes 131 on the support tube 13 here is only for example, not for limitation, and can be flexibly selected according to actual conditions.

[0048] The powder-producing part 20 is a solid structure and / or a powdery structure.

[0049] When the powder producing part 20 is a solid structure, such as a powder cake, the powder cake has a certain structure and is easy to assemble. However, in actual use, the solid powder cake needs to be vibrated by the vibrator 30 to gradually produce some powder. It takes a while for the powder to absorb the condensate. Moreover, when a small piece of the powder cake-like vibrator 30 is left, it is not easy to vibrate to produce powder, and the powder producing part 20 cannot be fully utilized.

[0050] When the powder producing part 20 is a powdery structure, a certain amount of powder or powder pile can be placed in the vibration space in advance. When the vibration part 30 vibrates, floating powder can be directly generated. The powdery powder producing part 20 is also easy to fully utilize, but the powdery structure of the powder producing part 20 is a little more troublesome to assemble.

[0051] When the powder-producing part 20 includes both a solid structure and a powdery structure, the advantages of the two structures can be well combined. What is more, there will be a gradient use process. For example, when the vibrating part 30 vibrates, the powdery powder-producing part 20 directly produces floating powder for adsorbing condensate. The solid powder-producing part 20 can produce powder to replace or make up for the amount of powder flowing out of the powder outlet 131 of the powdery powder-producing part 20 in the vibration chamber, so that the heating structure can continuously produce powder for cleaning the condensate, avoiding the phenomenon that the powder-producing part 20 is a powdery structure alone and is quickly used up and subsequently cannot play the condensate adsorption effect. The specific setting form of the powder-producing part 20 is selected according to the amount of condensate to be cleaned and the difficulty, and this application does not impose specific restrictions.

[0052] Specifically, the vibrating element 30 is an ultrasonic wave sheet, and / or the powder producing element 20 has a fragrance, and the fragrance is consistent with the taste of the atomized matrix in the liquid storage bin 70 after being atomized.

[0053] When the vibrating member 30 is an ultrasonic plate, it is convenient to provide a stable vibration frequency to the powder producing member 20, so that the powder producing member 20 can continuously produce powder, so that when the user sucks the suction nozzle 40, the powder continuously absorbs the condensate, which helps to clean or remove the condensate in the suction nozzle 40. The vibrating member 30 can be bonded and fixed in the powder storage member 10, or a card slot is provided in the powder storage member 10 to clamp the vibrating member 30. The specific fixing form of the vibrating member 30 is not limited in this application, as long as the fixing of the vibrating member 30 can be achieved.

[0054] The atomized gas generated after the atomized matrix in the liquid storage bin 70 is heated and atomized is used for users to inhale. The atomized gas has a specific taste, which is also the taste that users want to experience. If the condensed liquid is brought out by the tasteless powder and flows into the user's mouth, the condensed liquid cannot produce a taste consistent with the atomized gas, that is, when the user sucks on the mouthpiece 40 at this time, two tastes will be obtained, or the taste of the atomized gas will be weakened, affecting the suction experience. If at this time, the powder producing part 20 has a fragrance, and the fragrance is consistent with the taste of the atomized gas after the atomized matrix in the liquid storage bin 70 is atomized, the condensed liquid brought out by the powder can have the same or similar taste as the atomized gas, which better guarantees the consistency of the user's inhalation taste.

[0055] The substance capable of producing fragrance in the powder producing member 20 may be consistent with the substance capable of producing fragrance in the substrate to be atomized. For example, ethyl vanillin, ethyl maltol, linalool, rose alcohol, megastigmatrienone, methylcyclopentenolone or benzyl alcohol may be added to the powder producing member 20 to make the powder producing member 20 have fragrance and produce powder with fragrance.

[0056] See also Figure 1-Figure 4The powder storage member 10 includes a first base body 11 and a cover body 12 connected to each other. The first base body 11 is used to connect to the liquid storage bin 70, and the cover body 12 is located on a side of the first base body 11 away from the liquid storage bin 70. The first base body 11 and the cover body 12 enclose a hollow chamber, and the first base body 11, the cover body 12 and the outer wall of the support tube 13 enclose a vibration chamber.

[0057] Specifically, the first base body 11 has a side wall and a bottom plate, and the side wall and the bottom plate of the first base body 11 enclose a chamber that is recessed toward one side of the liquid storage bin 70. The side wall of the first base body 11 and one end of the liquid storage bin 70 are sleeved together, and the vibrating member 30 is fixed to the bottom plate in the first base body 11, for example, the vibrating member 30 is adhesively fixed to the bottom plate of the first base body 11. The first base body 11 and the cover body 12 can be an integral structure or two independent structures. In the embodiment of the present application, the first base body 11 and the cover body 12 are two detachable structures to facilitate maintenance of the vibrating member 30 and the powder producing member 20 in the vibration chamber, for example, replenishing the powder producing member 20 in the vibration chamber, wherein the cover body 12 is sleeved and fixed to the side wall of the first base body 11.

[0058] See also Figure 3-Figure 4 More specifically, a first through hole 111 is formed on the first base body 11, and a second through hole 121 is formed on the cover body 12. The support tube 13 and the liquid storage tank 70 are connected through the first through hole 111, and the support tube 13 and the air outlet pipe 41 are connected through the second through hole 121.

[0059] One end of the support tube 13 is fixed to the first through hole 111 or the first seat body 11 at the first through hole 111, and the other end of the support tube 13 is sleeved with the second through hole 121, or the other end of the support tube 13 is abutted against the cover body 12 at the second through hole 121; or, one end of the support tube 13 is fixed to the second through hole 121 or the cover body 12 at the second through hole 121, and the other end of the support tube 13 is sleeved with the first through hole 111, or the other end of the support tube 13 is abutted against the first seat body 11 at the first through hole 111. One end of the air outlet pipe 41 close to the cover body 12 is connected to the cover body 12 or the support tube 13. There is no specific restriction on the connection object of the air outlet pipe 41, as long as the air tightness of the adjacent positions of the air outlet pipe 41 and the support tube 13 can be guaranteed, that is, the powder and atomized gas in the support tube 13 can only flow into the air outlet pipe 41 when the user draws in the suction nozzle 40, avoiding the powder and atomized gas from running to other places (for example, into the suction nozzle 40 outside the air outlet pipe 41) to produce invalid suction.

[0060] Regarding the structural relationship between the first base body 11, the cover body 12, the support tube 13 and the air outlet pipe 41, Figure 1For example, to facilitate assembly, the support tube 13 and the first cover body 12 are an integral structure, one end of the support tube 13 is fixed to the bottom plate of the first base body 11 at the first through hole 111, and the other end of the support tube 13 is in contact with the inner wall of the cover body 12 at the second through hole 121 (i.e., the wall surface close to the first base body 11). An assembly tube 122 is integrally fixed to the outer wall of the cover body 12 at the second through hole 121 (i.e., the wall surface away from the first base body 11), and the end of the air outlet pipe 41 close to the cover body 12 is sleeved with the assembly tube 122, and a sealing ring 50 (e.g., a silicone sealing ring 50) is provided between the air outlet pipe 41 and the assembly tube 122 to ensure the sealing of the connection between the air outlet pipe 41 and the assembly tube 122.

[0061] In other embodiments, correspondingly, the support tube 13 can also be an integral structure with the cover body 12, and one end of the support tube 13 away from the cover body 12 abuts against the bottom plate of the first cover body 12 at the first through hole 111, or the support tube 13 is a relatively independent structure, and both ends of the support tube 13 respectively abut against the bottom plate of the first seat body 11 and the cover body 12.

[0062] In other embodiments, the support tube 13 fixed to the first cover body 12 may not be in contact with the cover body 12, that is, there is some gap between the end of the support tube 13 close to the cover body 12 and the inner wall of the cover body 12. At this time, the end of the air outlet pipe 41 can pass through the second through hole 121 and abut or sleeve against the end of the support tube 13 close to the cover body 12.

[0063] See also Figure 5 More preferably, in the embodiment of the present application, a guide tube 14 is provided in the support tube 13, and the guide tube 14 has a head end and a tail end, the head end is located near the side of the gas outlet pipe 41, and the tail end is located near the side of the liquid storage tank 70. An annular plate 141 is provided at the tail end of the guide tube 14, and along the radial direction of the guide tube 14, one side of the annular plate 141 is connected to the guide tube 14, and the other side of the annular plate 141 is connected to the support tube 13. A guide gap is formed between the outer wall of the guide tube 14 and the inner wall of the support tube 13, and the guide gap is used to allow the powder flowing out of the powder outlet hole 131 to flow to the outside of the suction nozzle 40 along the side of the inner wall of the gas outlet pipe 41. It can be understood that in order to facilitate the powder to flow into the air outlet pipe 41 through the guide gap, the powder outlet holes 131 need to be avoided at the inner wall where the annular plate 141 and the support tube 13 are connected, so that all the powder outlet holes 131 on the support tube 13 are placed on the side of the annular plate 141 close to the air outlet pipe 41, avoiding the phenomenon of separating the powder outlet holes 131 on the side of the annular plate 141 close to the liquid storage tank 70.

[0064] By providing the guide tube 14, the powder flowing out of the powder outlet hole 131 can be assisted to flow toward the outside of the suction nozzle 40 along the radial direction of the outlet pipe 41 close to the side wall of the outlet pipe 41 under the action of suction force (such as Figure 5In this way, the powder flowing out of the powder hole 131 can be brought into contact with and adsorbed by the condensate on the inner wall of the air outlet pipe 41 as much as possible, thereby ensuring the cleaning effect and cleaning speed of the condensate. It can also avoid as much as possible the phenomenon that the powder flows out of the powder hole 131 and flows to the center of the air outlet pipe 41, because the powder cannot be brought into contact with and adsorbed by the condensate on the side wall of the air outlet pipe 41, and is invalid powder, which will reduce the powder utilization rate and weaken the cleaning effect of the condensate.

[0065] The annular plate 141 can, on the one hand, play a role in fixing or assembling the guide tube 14 in the support tube 13, and on the other hand, can play a role in intercepting powder, because when the user is sucking the suction nozzle 40, there will always be a pause, at this time, the powder flowing out of the powder outlet hole 131 may not have time to flow out of the guide gap, under the action of the annular plate 141, this part of the powder can be temporarily collected in the guide gap, and when the subsequent suction is carried out, it will continue to flow to the side of the air outlet pipe 41. If the annular plate 141 is not provided, the powder cannot be intercepted and collected, and the powder may fall into the liquid storage bin 70 through the first through hole 111, which will affect the material or structure in the liquid storage bin 70.

[0066] Preferably, the end of the guide tube 14 close to the outlet pipe 41 can also extend into the outlet pipe 41, so that the powder in the guide gap can be more fully guided to the side close to the side wall of the outlet pipe 41, so as to better exert the adsorption effect of the powder on the condensate. At this time, the radial dimension of the outer wall of the guide tube 14 can be slightly smaller than the inner diameter of the outlet pipe 41, for example, the outer diameter of the guide tube 14 is 0.1mm-0.5mm smaller than the inner diameter of the outlet pipe 41, so that it can not only guide the powder in the guide gap, but also gather the powder in the guide gap, so that the powder in the guide gap flows to the condensate at a higher flow rate, so that the powder and the condensate contact and produce an adsorption effect.

[0067] See also Figure 6-Figure 7 In some embodiments of the present application, the heating structure also includes a filter 60, and an installation groove 42 connected to the air outlet pipe 41 is provided in the end of the suction nozzle 40 away from the powder storage member 10, and the filter 60 can be removably fixed in the installation groove 42, and the filter 60 is used to adsorb powder containing condensate.

[0068] The filter 60 is placed in the mounting groove 42 instead of on the side of the suction nozzle 40 away from the cover body 12, so that when the user sucks on the suction nozzle 40, the filter 60 is at a distance from the user's mouth, thereby avoiding discomfort caused by contact between the filter 60 and the user's mouth, and at the same time, avoiding contact between the user's mouth and the powder containing condensate adsorbed on the filter 60.

[0069] The filter 60 is, for example, a steel mesh made of stainless steel. The filter 60 prevents the condensate from coming into contact with the user's mouth and causing discomfort to the user. When the user sucks the suction nozzle 40, he can not only suck the atomized gas generated after the atomized matrix is ​​heated and atomized in the liquid storage tank 70, but also absorb the powder containing the condensate through the filter 60. The atomized gas and the condensate are two almost relatively independent components, which do not interfere with each other or have little interference, especially when the powder has no fragrance, so as to prevent the condensate and the atomized gas from flowing into the user's mouth together, weakening the taste of the atomized gas or conflicting with the taste of the atomized gas.

[0070] Since the filter 60 is detachably fixed in the mounting groove 42, when the filter 60 has absorbed the condensate or absorbed most of the condensate, the filter 60 can be removed without affecting the smoothness of the atomized gas flow when the heating structure is used later. After a period of time, a new filter 60 is continuously installed in the mounting groove 42 to play the role of absorbing the condensate in the suction nozzle 40. Of course, in other embodiments, the filter 60 can always be set in the mounting groove 42 to play the role of absorbing and collecting the condensate in the suction nozzle 40, and a new filter 60 can be replaced regularly.

[0071] See also Figure 7 Specifically, in some embodiments of the present application, a convex ring 43 protruding toward a side away from the air outlet pipe 41 is provided at the bottom of the installation groove 42, and the filter element 60 is a filter screen cover, which is sleeved and fixed on the convex ring 43. In order to ensure the compactness of the suction nozzle 40, the shape of the installation groove 42 needs to be at least partially compatible with the shape of the filter screen cover, so that the installation groove 42 and the filter screen cover are tightly matched, and the installation firmness of the filter screen cover in the installation groove 42 is ensured. Due to the limited space in the installation groove 42, an avoidance position 44 is provided in the installation groove 42, and the avoidance position 44 is similar to the notch or slot provided in the installation groove 42, so as to facilitate the removal of the filter element 60. In other embodiments, the filter element 60 can also be in other detachable ways, for example, the filter element 60 is directly detachably connected to the groove wall of the installation groove 42, and there is no specific restriction on the detachable way of the filter element 60, as long as the detachable installation of the filter element 60 can be achieved. Of course, in other embodiments, the filter element 60 may be directly fixed in the installation groove 42 in a non-detachable manner according to usage requirements.

[0076] The atomizing tube 100 is sleeved in the air flow channel, and the atomizing assembly 110 includes a liquid guide 111 and a heating element 112. A portion of the liquid guide 111 is sleeved in the atomizing tube 100, and the rest of the liquid guide 111 extends into the liquid storage part 90. The liquid guide 111 located in the atomizing tube 100 is tubular, and the heating element 112 is fixed to the inner wall of the tubular liquid guide 111. Both ends of the atomizing chamber formed in the tubular liquid guide 111 are connected to the atomizing airway formed in the atomizing tube 100. Among them, the liquid guide 111 is a porous material, such as a porous material such as porous ceramics. The heating element 112 is, for example, a heating sheet, a heating net, a heating wire, etc. The liquid guide 111 is used to contact and absorb the substrate to be atomized in the liquid storage part 90, and transfer the substrate to be atomized to the heating element 112. The heating element 112 is used to heat the substrate to be atomized on the liquid guide 111 and generate atomized gas.

[0077] More preferably, to ensure the sealing of the liquid storage chamber, the first seat body 11 and one end of the liquid storage bin 70 are sealed together, and the second seat body 80 and the other end of the liquid storage bin 70 are also sealed together. The first seat body 11 and the second seat body 80 are both made of silicone material, for example, to achieve sealing at the connection with the liquid storage bin 70.

For example, the liquid storage tank 70 is similar to a rectangular or elliptical shell, and correspondingly, the first base body 11, the second base body 80 and the cover body 12 are also similar to rectangular or elliptical objects. At this time, the first base body 11 has a length direction and a width direction, and the vibration members 30 and the powder producing members 20 can be respectively provided on both sides of the support tube 13 in the length direction of the first base body 11, and the length direction and width direction of the first base body 11 are both perpendicular to the axial direction of the first through hole 111.

The next step is to assemble the rest of the heating structure. There is no restriction on the order of the assembly steps mentioned here, as long as the assembly of the heating structure can be achieved. According to the described assembly process of the heating structure, it can be seen that the heating structure designed in the present application is simple, easy to assemble, and easy to implement.

[0080] The heating structure in the above embodiment designed by the present application, when the user inhales, the vibrating member 30 starts to work, and the powder producing member 20 generates powder floating in the vibration chamber through the vibration of the vibrating member 30. Then, under the suction force provided by the user, the powder flows through the powder outlet hole 131 and the support tube 13 to the air outlet pipe 41 in sequence, and with the user's suction action, the condensate on the side wall of the air outlet pipe 41 is absorbed little by little, and the powder containing the condensate continues to flow outside the suction nozzle 40 or the user's mouth to achieve the cleaning or removal of the condensate.

[0081] See also Figure 1 and Figure 6 In another embodiment of the present application, an electronic atomizer is provided, comprising: a power supply (not shown), a mainboard (not shown) and a heating structure as in the above embodiment, the power supply and the vibrating member 30 are electrically connected to the mainboard respectively, the power supply is used to provide electric energy to the vibrating member 30, and the mainboard is used to control the working state of the vibrating member 30, for example, the mainboard controls the start or stop of the vibrating member 30. The electronic atomizer includes the heating structure in the above embodiment, and therefore, also has the advantages of the heating structure in the above embodiment, so it will not be elaborated here.

[0082] The electronic atomizer also includes a shell 120 and a bracket body 130. The heating structure, power supply, main board, and bracket body 130 are all located in the shell 120. An air inlet 121 is provided on the side of the shell 120 away from the liquid storage tank 70, and an air inlet pipe 131 is provided on the bracket body 130. One end of the air inlet pipe 131 is connected to the air inlet 121, and the other end of the air inlet pipe 131 is connected to the atomization pipe 100 in the liquid storage tank 70. When the user draws the electronic atomizer, the external air flow flows to the user's mouth at the suction nozzle 40 through the air inlet 121, the air inlet pipe 131, the atomization pipe 100, the support tube 13, and the air outlet pipe 41 in sequence. A buckle portion 45 is provided at one end of the suction nozzle 40 close to the cover body 12, and the suction nozzle 40 is disassembled and fixed to the shell 120 through the buckle portion 45, so as to facilitate the cleaning of the powder outlet hole 131 in the support tube 13. The vibration member 30 in the first base body 11 is electrically connected to the main board via leads, and the leads may be led out from the side wall of the first base body 11 to achieve electrical connection between the vibration member 30 and the main board.

[0083] Specifically, the heating structure in the electronic atomizer includes a filter 60, and a mounting groove 42 connected to the air outlet pipe 41 is provided in the end of the suction nozzle 40 away from the powder storage member 10, and the filter 60 is detachably fixed in the mounting groove 42, and the filter 60 is used to adsorb powder containing condensate.

The electronic atomizer includes a first working state and a second working state. In the first working state, the filter 60 is removed from the mounting groove 42, and the switch is used to send a first signal to the mainboard to control the working state of the atomizer assembly 110. In the second working state, the filter 60 is installed in the mounting groove 42, and the switch is used to send a second signal to the mainboard to control the working state of the vibrator 30 and the atomizer assembly 110.

[0084] The first signal is, for example, a signal for controlling the start or shut down of the atomizing assembly 110. The second signal is, for example, a start signal for controlling the synchronization or asynchronous operation of the vibrating member 30 and the atomizing assembly 110, and a shut down signal for controlling the synchronization or asynchronous operation of the vibrating member 30 and the atomizing assembly 110. Two switches (not shown) can be provided according to the type of signal, one switch is responsible for providing the first signal to the mainboard, and the other switch is responsible for providing the second signal to the mainboard, or, in other embodiments, only one switch is provided, but it has two operation modes, for example, one operation mode is a long press operation, and the other operation mode is a short press operation, for generating the first signal or the second signal.

[0085] By combining the filter 60 with the second working state, the condensate in the mouthpiece 40 of the electronic atomizer can be cleaned regularly. When the condensate does not need to be cleaned, the filter 60 can be removed. When the user uses the electronic atomizer in the first working state, there is no obstruction of the filter 60, which can ensure smooth suction of atomized gas.

[0086] Of course, in other embodiments, the electronic atomizer may not be provided with the filter element 60, or the filter element 60 may be directly fixed in the nozzle 40. In this case, the vibration element 30 and the atomization assembly 110 can work together (synchronously or asynchronously without restriction), and there is no need to distinguish between the first working state and the second working state.
