Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to a heating module, and even more specifically to an atomization device. Background Technology

[0002] The most common atomization method used in current atomizing devices is heating atomization. Specifically, a heating wire is placed close to the collecting liquid, and the atomizing liquid temporarily stored in the collecting liquid is heated by the heating wire. However, the inventors discovered the following problem when using existing atomizing devices:

[0003] Heated atomization works by evaporating the atomizing liquid through heating. The evaporation process absorbs a significant amount of heat, depending on the required temperature, ensuring the collector liquid temperature remains stable while the heating wire heats the liquid. When the atomizing liquid in the collector is completely atomized without replenishment, the atomization device should be shut off or replenished promptly. However, users often fail to notice liquid shortages within the atomization device, making it easy for the heating wire to continue heating even when insufficient. Without heat absorption from liquid evaporation, the temperature of the collector liquid rises sharply, causing the heating wire to burn and produce a burnt smell. Users only realize the liquid shortage after inhaling the burnt gas. This significantly impacts the user experience, and prolonged dry burning of the collector liquid also shortens its lifespan. To prevent burnt smells from dry burning, a heating module capable of monitoring and responding promptly to dry burning issues is urgently needed in the atomization device. Summary of the Invention

[0004] Therefore, it is necessary to address the dry burning problem in the existing technology by providing a heating module and atomizing device.

[0005] In a first aspect, this application provides a heating module, comprising:

[0006] Heating element; and

[0007] The connection terminal includes an electrode electrically connected to the heating element, and a fixing member that keeps the electrode connected to the heating element;

[0008] The fastener can undergo thermal melting deformation when heated, and when the fastener undergoes thermal melting deformation, the electrode shifts and disconnects from the heating element.

[0009] In the heating module described above, the electrodes are supported by a rigid fixing member so that the electrodes can contact the heating wire to achieve electrical connection. Simultaneously, the fixing member can be thermally deformed to disconnect the electrical connection between the electrodes and the heating wire. Melting of the fixing member controls the heating wire to stop operating, thus protecting the heating module.

[0010] In one embodiment, the heating element is provided with contact points, and the electrodes abut against the contact points.

[0011] In one embodiment, the heating element has contact points at both ends, and the contact surfaces of the two contact points that abut against the electrodes are on the same plane.

[0012] In one embodiment, the fastener is detachably connected to the electrode.

[0013] In one embodiment, the fastener is connected to the electrode so that the electrode remains in a deformed state, and the electrode in the deformed state is in a first position electrically connected to the heating element.

[0014] When the fastener is deformed by heat melting, the electrode springs back from the first position to the second position.

[0015] In one embodiment, the electrode includes an elastic contact piece, and the fixing member includes a connecting plate body located between two free portions of the contact piece and providing a force that moves the two free portions away from each other so as to keep the electrode in a deformed state, with the two free portions in contact with the contact point.

[0016] In one embodiment, the connecting plate body is provided with two parallel fixing grooves, and the electrode is bent so that the free part is correspondingly engaged in the fixing groove.

[0017] In one embodiment, the free portion passes through the fixing groove and protrudes from the connecting plate body.

[0018] In one embodiment, the electrode includes an elastic contact piece, which includes two free portions and a top located between the two free portions. The top is bent toward the contact point relative to the free portions. The free portions of the arc-shaped contact piece are connected to the heating element by a fastener so that the top is bent and contacts the contact point.

[0019] In one embodiment, the fastener is made of resin.

[0020] In one embodiment, the resin includes PF, EP, PEEK, and PI.

[0021] In one embodiment, the fastener is made of thermoplastic; the fastener has a cooled, reset state.

[0023] The atomizing device also includes a bottom shell, which is detachably connected to the main body.

[0024] In the atomizing device described above, the heating module automatically shuts off and stops working when overheating, preventing the atomizing device from burning due to insufficient liquid and producing a burnt smell, which would negatively impact the user experience. Simultaneously, the bottom shell is detachably connected to the main body, exposing the interior of the main body and facilitating the replacement and cleaning of internal components, thus improving maintenance convenience.

[0052] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention.

[0058] The atomizing device disclosed in this application is mainly used to convert atomizing liquid into aerosol. An aerosol is a colloidal dispersion system formed by the dispersion and suspension of solid or liquid particles in a gaseous medium. Since aerosols can be absorbed by the human body through the respiratory system, they provide users with a novel alternative absorption method. Currently, atomizing liquids (hereinafter referred to as liquids) include, but are not limited to, e-liquids containing nicotine, medical drugs, and skin lotions. Atomizing these liquids can deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0059] refer to Figure 3 , 4 , Figure 3 This is a three-dimensional structural diagram of the atomizing device provided in some embodiments of this application. Figure 4 This is a cross-sectional view of an atomizing device provided in some embodiments of this application. For ease of explanation, the following embodiments use an atomizing device from a specific embodiment provided in this application for illustration.

[0060] In some embodiments of this application, an atomizing device is provided, including a bottom 100, a main body 200, and a top cover 300. The main body 200 houses a heating module and a liquid collector 240, which temporarily stores the atomizing liquid supplied from a liquid storage tank 211. The bottom 100 and the top cover 300 are respectively connected to the main body 200.

[0061] In this design, the main body 200 includes a housing 210, which is hollow to provide space for a heating module and a liquid collector 240. The heating module is positioned close to the liquid collector 240 and heats the liquid temporarily stored in the liquid collector 240, causing the liquid to atomize into gas or aerosol.

[0062] For example, further reference Figure 5 , Figure 5 for Figure 4 A partially enlarged schematic diagram at point A. The interior of the casing 210 is divided into an independent liquid storage chamber 211 and a flue 212. The flue 212 extends in a straight line within the main body 200, with the liquid storage chamber 211 located on either side of the flue 212. A liquid collector 240 is mounted within the flue 212, positioned along the gas flow path. Both ends of the liquid collector 240 extend into the liquid storage chamber 211 to guide the liquid to the middle section of the liquid collector 240 for atomization. The middle section of the liquid collector 240 is located within the flue 212, facilitating the delivery of the atomized gas through the flue 212 to the atomizing device.

[0063] In some embodiments of this application, reference is made to Figure 1 , Figure 1 This is a three-dimensional structural diagram of a heating module provided in some embodiments of this application. The heating module provided in this application includes a heating element 230 and a connecting terminal 120. The connecting terminal 120 is electrically connected to the heating element 230, and the connecting terminal 120 can be detached from the heating element 230. The operation of the heating element 230 is controlled by detaching or connecting the connecting terminal 120 to the heating element 230. The connecting terminal 120 is used to connect the heating element 230 to a power source. The connecting terminal 120 needs to be electrically connected simultaneously to the heating element 230 located inside the flue 212 and to a power source located outside the main body 200.

[0064] Therefore, in this solution, the connection terminal 120 is connected to the power supply via the bottom 100, so that the connection terminal 120 forms a transmission channel for power supply to the heating element 230, and supplies the power of the power supply to the heating element 230.

[0065] Meanwhile, the heating element 230 is positioned close to the atomizing surface of the liquid collector 240 to facilitate the transfer of more heat from the heating element 230 to the liquid collector 240 for heating the liquid temporarily stored within the liquid collector 240. Specifically, the atomizing surface of the liquid collector 240 is located within the flue 212, and the heating element 230 is positioned within the flue 212 to facilitate proximity to the atomizing surface of the liquid collector 240.

[0066] Among them, reference Figure 2 , Figure 2 This is a three-dimensional structural diagram of the heating module and liquid collector provided in some embodiments of this application. Exemplarily, the heating element 230 has contact points 232 at both ends, and the connecting terminals 120 are electrically connected to the contact points 232. The heating element 230 includes a spiral heating wire 231, the contact points 232 are located at both ends of the spiral heating wire 231, and the spiral heating wire 231 is wound around the liquid collector 240, thus limiting and fixing the spiral heating wire 231 to the liquid collector 240. The two contact points 232 are on the same plane, and the two connecting terminals 120 simultaneously abut against the contact points 232, making the heating element 230 and the connecting terminals 120 electrically connected.

[0067] More specifically, the heating element 230 can be selected from synthetic graphite, iron-chromium-aluminum, nickel, stainless steel, carbon fiber, or any of the above components combined with other slurries to form a heating wire or heating mesh with heating function. The thickness or diameter of the heating element 230 ranges from 12 to 40 micrometers.

[0068] Further reference Figure 7 , Figure 7 This is a three-dimensional structural diagram of a connection terminal provided in some embodiments of this application. The connection terminal 120 includes a fixing member 121 and an electrode 122. The electrode 122 is electrically connected to the contact point 232 through the fixing member 121. The fixing member 121 is made of resin. When the fixing member 121 absorbs heat and its temperature rises to a certain temperature (corresponding to the hot melt temperature of the resin), the fixing member 121 will soften and become difficult to maintain its rigidity.

[0069] Specifically, the fixing member 121 possesses a certain rigidity before reaching its heat-melting temperature, allowing it to maintain a rigid state. This rigidity supports the electrode 122 in the first position, where it contacts the contact point 232 and forms an electrical connection. However, when the temperature on the fixing member 121 reaches the heat-melting temperature of the heat-melting medium layer, the medium layer undergoes thermal deformation, causing the fixing member 121 to soften and weaken. This weakens the fixing member 121's rigidity, making it difficult to support the electrode 122 in the first position. Due to its own force, the electrode 122 returns to the second position. When the electrode 122 is in the second position, it disengages from the contact point 232, breaking the connection, and the heating element 230 ceases operation.

[0070] More specifically, when the temperature on the fixing member 121 is higher than the melting temperature of the fixing member 121, the resin material undergoes thermal deformation, making it difficult for the fixing member 121 to support the electrode 122. This causes the electrode 122 to detach from the contact point 232, breaking the connection between the connection terminal 120 and the heating element 230, thereby suspending the heating operation of the heating element 230.

[0071] Furthermore, the connecting terminal 120 and the heating element 230 form an electrical connection structure. Since the heating element 230 is located close to the liquid collector 240, the connecting terminal 120, which is in contact with the heating element 230, is also located close to the liquid collector 240. When the heating element 230 heats the liquid temporarily stored in the liquid collector 240, the heat generated by the heating element 230 is absorbed by the liquid through evaporation, thus maintaining the temperature inside the atomization chamber of the atomizing device at a relatively stable temperature. Consequently, the heat transferred to the connecting terminal 120 also keeps the connecting terminal 120 at a stable temperature. However, when the liquid in the liquid collector 240 is completely atomized, there is a shortage of liquid in the liquid collector 240. At this time, the heat generated by the heating element 230 will be transferred to the liquid collector 240, but because there is no liquid evaporation to absorb heat, the temperature of the liquid collector 240 will rise sharply, and the heating element 230 will dry-burn the liquid collector 240. As the temperature of the liquid collector 240 rises sharply, the heat on the liquid collector 240 will be conducted to the nearby connection terminal 120, and as the temperature of the liquid collector 240 rises, the temperature of the connection terminal 120 will rise sharply.

[0072] In this design, the retainer 121 within the connecting terminal 120 will lose rigidity when the temperature rises to the heat-melting temperature, making it difficult for the retainer 121 to support the electrode 122. The retainer 121 is used to monitor the temperature of the collecting liquid 240, thereby enabling monitoring of the dry burning of the collecting liquid 240. Simultaneously, because the retainer 121 will melt when heated, the heating element 230 can be paused when the collecting liquid 240 is dry-burning, allowing for accurate control of the heating element 230's operation to prevent dry burning.

[0073] In this application, the fastener 121 is made of resin. Utilizing the property of resin to melt when heated, the fastener 121 deforms, thereby disconnecting the connection terminal 120 from the heating element 230. It should be noted that the fastener 121 is not limited to being made of heat-meltable resin; it can also be made of shape memory metal. However, shape memory metal is conductive, and to avoid short circuits, it requires insulation treatment, increasing manufacturing costs and complicating operation. Furthermore, the heat distortion temperature of shape memory metal is relatively fixed, limiting its applicability to a single temperature range. Therefore, in this application, the fastener 121 is preferably made of resin.

[0074] Existing atomizing devices often employ a single overload protection device, resulting in a fixed threshold value, specifically a fixed melting temperature. However, atomizing devices often need to atomize multiple types of liquids, leading to variations in evaporation temperatures when atomizing different types of liquids.

[0075] When atomizing liquids with evaporation temperatures below the overload protection device threshold, the heating element 230 may dry-burn before reaching the overload protection device threshold. Before the overload protection device disconnects, the user has already begun inhaling a burnt-smelling gas, negatively impacting the user experience.

[0076] Conversely, when atomizing liquids with evaporation temperatures higher than the overload protection device threshold, the heating temperature on the heating element 230 exceeds the overload protection device threshold before the liquid is fully atomized or atomized, causing the overload protection device to disconnect prematurely. Incomplete atomization of the liquid within the atomizing device makes it easier for users to inhale the liquid, affecting the taste.

[0077] In this design, the atomizing device includes multiple fasteners 121 made of different resin materials. The different resin materials have different melting temperatures, resulting in varying temperatures required to disconnect the connection terminal 120 from the heating element 230 when different fasteners 121 are installed within the heating module. Based on the different melting temperatures of each fastener 121, in this design, the user can determine the type of fastener 121 to use according to the type of liquid to be atomized within the atomizing device; that is, the heat-melting temperature of the fastener 121 is determined by the type of liquid required for atomization. The selected fastener 121 type is compatible with the type of liquid. The connection terminal 120 can precisely heat-melt the fastener 121 from the heating element 230 at a rated temperature.

[0078] The threshold values ​​of the fixing parts 121 are different when made of different types of resins. The corresponding fixing parts 121 are selected according to the type of liquid so that the liquid evaporation temperature matches the threshold value of the fixing parts 121, thereby improving the sensitivity of the connection terminal 120 when disconnecting and avoiding the problems of dry burning or incomplete atomization of the atomizing device.

[0079] For example, each fixing member 121 is made of PF, EP, PEEK, or PI, and the fixing members 121 made of different resin materials are selected according to the atomization temperature of different types of atomizing liquids, including:

[0080] When the atomization temperature of the liquid used for atomization in the atomizing device is below 200℃, the hot melt material of the fixing part 121 shall be PF;

[0081] When the atomization temperature of the liquid used for atomization in the atomizing device is lower than 230℃, the hot-melt material of the fixing part 121 shall be EP or PEEK.

[0082] When the atomization temperature of the liquid used for atomization in the atomizing device is lower than 270℃, the hot-melt material of the fixing part 121 shall be PI.

[0083] The hot melt medium layer within the fixing member 121 is made of resin material. When the temperature of the hot melt medium layer reaches its melting temperature, the rigidity of the hot melt medium layer weakens, and the hot melt medium layer softens and deforms. Consequently, the electrode 122, which is originally supported by the fixing member 121 and electrically connected to the heating element 230, will shift. The shifted electrode 122 will disconnect from the heating element 230, and the heating element 230 will stop working. On the other hand, the resin material that has undergone hot melt deformation can be easily reprocessed into the original shape of the fixing member 121 for reuse, thereby improving utilization and saving raw materials.

[0084] In some embodiments of this application, the electrode 122 is brought into contact with the contact point 232 by the fixing member 121 to ensure electrical connection between the electrode 122 and the contact point 232. On the other hand, due to the heat deformation of the fixing member 121 and the selection of different materials for the fixing member 121 according to the type of liquid, the fixing member 121 in this solution is detachably connected to facilitate replacement of the fixing member 121.

[0085] In the first embodiment of this application, as Figure 1 , 7 As shown, the fixing member 121 connects to the electrode 122, forcing the electrode 122 to deform. After deformation, the electrode 122 is in a first position. The fixing member 121 causes the electrode 122 to elastically deform and holds the electrode 122 in the deformed shape. The deformed electrode 122 contacts the contact point 232 to achieve electrical connection. When the heat transferred from the heating element 230 to the fixing member 121 raises the temperature of the fixing member 121 to the melting temperature, the fixing member 121 melts, causing the supporting force that originally restricted the return of the electrode 122 to be removed. The electrode 122 springs back to its original position and returns to the second position. The electrode 121 in the second position disengages from the contact point 232, the connecting terminal 120 is disconnected from the heating element 230, and the heating element 230 stops working.

[0086] In this plan, such as Figure 7 As shown, and further reference Figure 8 , Figure 8 This is a perspective structural diagram of a fastener provided in some embodiments of this application. The electrode 122 includes an elastic contact piece. The contact piece includes a free portion 1221 and a top 1222 located between the two free portions 1221. The fastener 121 includes a connecting plate body 1211 located between the two free portions 1221 of the contact piece and providing a force that moves the two free portions 1221 away from each other, thereby keeping the electrode 122 in a deformed state. The two free portions 1221 are in contact with the contact point 232. In the deformed state, the electrode 122 is in a first position electrically connected to the heating element 230.

[0087] In one specific embodiment, the connecting plate body 1211 is provided with two parallel fixing grooves 1212. The free portions 1221 of the electrode 122 are respectively engaged in the fixing grooves 1212, forcing the electrode 122 to bend and deform. Specifically, by bending the electrode 122 so that the two free portions 1221 of the electrode 122 are parallel to each other, the two ends of the electrode 122 are inserted into the fixing grooves 1212, so that the electrode 122 is connected to the fixing member 121 and the electrode 122 is kept in a bent and deformed state.

[0088] A fixing groove 1212 is formed on the connecting plate body 1211, extending to one side of the connecting plate body 1211, so that two connecting posts 1213 are formed on the connecting plate body 1211 to correspond to the fixing groove 1212 respectively. A bent electrode 122 is inserted into the fixing groove 1212 from one side of the connecting plate body 1211 to realize the connection between the fixing member 121 and the electrode 122.

[0089] More specifically, the top 1222 is bent into a U-shape. When the electrode 122 is connected to the connecting plate body 1211, the free part 1221 protrudes from the connecting plate body 1211 and contacts the contact point 232.

[0090] Furthermore, the flue 212 extends vertically, forming an opening on at least one side of the housing 210. The connecting terminal 120 extends from this opening, passes through the bottom 100, and is connected to the power supply, thus forming a transmission channel for powering the heating element 230. The opening facilitates the passage of the connecting terminal 120 to avoid interference between the connecting terminal 120 and the housing 210. Figure 4 and refer to Figure 9 , 10 , Figure 9 This is a schematic diagram of gas flow inside the casing provided in some embodiments of this application. Figure 10 This is a cross-sectional view of the housing provided for some embodiments of this application. In this embodiment, the flue 212 extends to form openings on the corresponding two side faces of the housing 210.

[0091] Specifically, the opening includes a first opening 2122 and a second opening 2123. The first opening 2122 is located on the top surface of the housing 210 and is covered by an upper cover 300 mounted on the main body 200. The first opening 2122 serves as the outlet of the flue 212, and the upper cover 300 has an outlet 310 that penetrates through it. The outlet 310 connects to the flue 212, allowing gas generated within the flue 212 to enter the outlet 310 via the flue 212 and ultimately exit from the upper cover 300.

[0092] The second opening 2123 is located on the bottom surface of the housing 210. The bottom 100 is detachably connected to the bottom surface of the main body 200, and the bottom 100 covers the second opening 2123. The connecting terminal 120 is installed on the bottom 100, and when the bottom 100 is connected to the main body 200, the connecting terminal 120 is electrically connected to the heating element 230. When the bottom 100 is detached from the main body 200, the connecting terminal 120 is removed from the second opening 2123 along with the bottom 100. Installing the connecting terminal 120 on the bottom 100 facilitates the removal of the connecting terminal 120 from the atomizing device and makes it convenient to replace the fixing part 121.

[0093] For example, the connection terminal 120 also includes an electrode post 123 and a connection end 124. One end of the electrode post 123 is connected to the top 1222, and the connection end 124 is mounted on the other end of the electrode post 123. The connection end 124 is fixedly connected to the bottom 100 and is exposed outside the atomizing device to facilitate power supply to the connection end 124. The electrode 122, electrode post 123, and connection end 124 are sequentially connected to each other so that current can be introduced into the heating element 230 through the connection end 124, electrode post 123, and electrode 122.

[0094] When the bottom 100 is connected to the main body 200, the free portion 1221 presses against the contact point 232, causing the free portion 1221 to deform so that more of its area is pressed against the contact point 232, thus ensuring the stability of the connection between the electrode 122 and the contact point 232. More specifically, the free portion 1221 is provided with a groove. When the electrode 122 is inserted into the fixing member 121, the electrode 122 is subjected to a rebound force, and the top 1222 abuts against the connecting post 1213. At this time, the groove engages with the edge of the connecting post 1213 to prevent the top 1222 from retracting into the fixing groove 1212 under pressure when it is pressed against the contact point 232, thus affecting the stability of the connection.

[0095] In another specific embodiment, when the two free parts 1221 are closed together, they are in a second position. The fastener 121 supports the two free parts 1221 between them, keeping the free parts 1221 deformed and in a first position. When the fastener 121 is heated and softened, the two free parts 1221 return to their original position and close inward, causing the free parts 1221 to disengage from the heating element 230, thereby disconnecting the connection.

[0096] In the second embodiment of this application, reference is made to Figure 11 , 12 , Figure 11 This is a three-dimensional structural diagram of a heating module provided in some embodiments of this application. Figure 12 for Figure 11 A partially enlarged schematic diagram at point B. Electrode 122' is located directly below contact point 232; electrode 122' and contact point 232 are connected by fastener 121', and when electrode 122' is in the first position, electrode 122' contacts contact point 232 to achieve electrical connection. When fastener 121' is heat-fused, electrode 122' shifts from the first position to the second position, causing electrode 122' to detach from contact point 232. Fastener 121' is detachably connected to both electrode 122' and contact point 232 to facilitate removal and replacement. The connection method between fastener 121' and electrode 122' and contact point 232 can be selected from common detachable connection methods such as snap-fit, adhesive, or nesting.

[0097] In one specific embodiment, the electrode 122' includes a top 1222' and free portions 1221' located at both ends of the top 1222', with a fixing member 121' connected to the free portions 1221'. The fixing member 121' connects the free portions 1221' to the contact points 232, thereby limiting the position of the electrode 122' and the contact points 232, facilitating a stable connection structure between the fixing member 121' and the contact points 232. Specifically, when the fixing member 121' connects the free portions 1221' to the contact points 232, the electrode 122' and the contact points 232 are electrically connected. However, after the fixing member 121' is deformed by heat, it will be affected by the weight of the electrode 122', causing the fixing member 121' to be stretched, resulting in a shift in the position of the electrode 122' and the contact points 232. The electrode 122' then disconnects from the contact points 232, and the heating element 230 ceases operation.

[0098] In this design, the top 1222' is arched, and its highest point in the vertical direction contacts the contact point 232 to achieve electrical connection. In this embodiment, the electrical connection structure formed by the fixing member 121', electrode 122', and contact point 232 is stable. To improve response speed, the top 1222' is tangentially positioned to the contact point 232. After the fixing member 121' is heat-melted, the top 1222' can quickly detach from the contact point 232, effectively improving the response speed of the heating element 230 when it stops operating.

[0099] In another embodiment, electrode 122' includes an elastic contact piece, with its top 1222' bent relative to the free portion 1221' toward the contact point 232. The free portion 1221' of the curved contact piece is connected to the heating element 230 via a fastener 121, such that the top 1222' bends and contacts the contact point 232. When the fastener 121 connects the free portion 1221' to the heating element 230, the top 1222' is bent and deformed under force. When the fastener 121 softens due to heat, the top 1222' elastically recovers, causing the top 1222' to disengage from the contact point 232.

[0100] Furthermore, the flue 212 extends in a vertical straight direction, forming an opening on at least one side of the housing 210. The connecting terminal 120' extends from this opening, passes through the bottom 100, and is connected to the power supply, thus forming a transmission channel for powering the heating element 230. The opening facilitates the passage of the connecting terminal 120' and avoids interference. In this design, the flue 212 extends to form openings on corresponding two sides of the housing 210.

[0101] Specifically, the opening includes a first opening 2122 and a second opening 2123. The first opening 2122 is located on the top surface of the housing 210 and is covered by an upper cover 300 mounted on the main body 200. The first opening 2122 serves as the outlet of the flue 212, and the upper cover 300 has an outlet 310 that penetrates through it. The outlet 310 connects to the flue 212, allowing gas generated within the flue 212 to enter the outlet 310 via the flue 212 and ultimately exit from the upper cover 300.

[0102] The second opening 2123 is located on the bottom surface of the housing 210. The bottom 100 is detachably connected to the bottom surface of the main body 200, and the bottom 100 covers the second opening 2123. The connecting terminal 120' also includes an electrode post 123', which is connected to the top 1222' and passes through the bottom 100. In a preferred embodiment, after the bottom 100 is removed from the main body 200, the connecting terminal 120' extends from the second opening 2123 into the flue 212, and the connecting terminal 120' is installed onto the contact point 232. After the connecting terminal 120' is installed, the bottom 100 is then installed back onto the main body 200. Meanwhile, the electrode post 123' passes through the bottom 100, allowing the electrode 122' and the electrode post 123' to slide relative to the bottom 100, so that after the fixing member 121' is heat-melted, the electrode 122' can be offset and disengaged from the contact point 232.

[0103] refer to Figure 6 , Figure 6 This is a three-dimensional structural diagram of the bottom of the atomizing device provided in some embodiments of this application. In the two embodiments described above, the bottom 100 includes a bottom shell 110, the outline of which corresponds to the bottom surface outline of the main body 200, ensuring consistency when the bottom shell 110 is mounted on the main body 200. The bottom shell 110 has clearance holes for a connecting end 124 or electrode posts (123, 123'). Simultaneously, the bottom shell 110 also has an air inlet 111, which corresponds to a second opening 2123, facilitating the filling of external air into the flue 212. It should be noted that in the two embodiments described above, the number of sides of the flue 212 forming an opening on the main body 200 includes, but is not limited to, two. The flue 212 may also be formed on one side of the main body 200. The opening serves not only as the air outlet of the flue 212 but also as the protrusion of the connecting terminal 120.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
