[0025] To provide a clearer understanding of the technical features, objectives, and effects of this application, the specific embodiments of this application are now described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented 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 this application.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0030] Figures 1 to 5 An atomizer 1 according to one embodiment of this application is shown. The atomizer 1 can contain and atomize an aerosol generating matrix, which can generate aerosols after being heated and atomized. The aerosol generating matrix includes, but is not limited to, materials used for medical, health, and beauty purposes.

[0031] The atomizer 1 may include an atomizer body and a protective component 30. The protective component 30 is detachably mounted on the atomizer body to prevent leakage of the aerosol generation matrix or its volatile gases from the atomizer body.

[0032] like Figure 1 and Figure 2 As shown, the atomizer body may include a housing 10 and an atomizing component 20. The housing 10 defines a storage cavity 13, which contains an aerosol generating matrix. The atomizing component 20 is disposed within the housing 10 and is used to heat the aerosol generating matrix after being powered on, causing it to atomize and generate an aerosol. A protective component 30 is disposed on the housing 10 to reduce leakage of the aerosol generating matrix or its volatile gases, preventing condensation on the surface of the electrode 21 led out from the atomizing component 20.

[0033] The atomizing component 20 may include at least two electrodes 21, the ends of which are exposed outside the housing 10 to facilitate connection to an external power source for heating and atomizing the atomizing component 20 with the aerosol generating matrix. The protective component 30 may include a sealing layer 31, which is detachably attached to the outer surface of the housing 10 and detachably attached to the exposed ends of the electrodes 21 within the housing 10.

[0034] It should be understood that the atomizer 1 can be assembled with the atomizing host to form an electronic atomization device. The atomizing host is electrically connected to the atomizer 1 via electrode 21 to provide power to the atomization assembly 20. The atomizer 1 can work with the atomizing host to achieve the heating and atomization of the aerosol generation matrix.

[0035] See also Figure 3 and Figure 5The outer casing 10 further defines an air outlet channel 1121 and an air inlet 122. The atomizing assembly 20 defines an atomizing channel 231, the downstream of which is connected to the upstream of the air outlet channel 1121, and the upstream of which is connected to the air inlet 122. The atomizing assembly 20 also includes a heating element 22, which is disposed within the atomizing channel 231 and electrically connected to an electrode 21. The atomizing host can provide power to the heating element 22 through the electrode 21, so that the heating element 22 heats and atomizes the aerosol generating matrix. The storage chamber 13 can be connected to the atomizing channel 231, so that the aerosol generating matrix in the storage chamber 13 can flow to the heating element 22 in the atomizing channel 231 and be heated and atomized by the heating element 22.

[0036] During user operation, external gas can enter the atomization channel 231 through the air inlet 122 and mix with the aerosol matrix generated by the heating element 22. The mixture then flows out through the air outlet 1121 for user use. During this process, the end of the electrode 21 exposed outside the housing 10 can be electrically connected to the atomizing host to provide power to drive the heating element 22 to generate heat.

[0037] It is important to understand that the aerosol generating matrix may volatilize and produce gas at room temperature. Since both the aerosol generating matrix and its volatilized gas are fluids, they may seep out along the air inlet 122 or the gap connecting the outer casing 10 and the electrode 21. The aerosol generating matrix that seeps out of the outer casing 10 may cause a potential problem of re-condensation at the end of the electrode 21 exposed outside the outer casing 10, covering the surface of the electrode 21.

[0038] By providing a sealing layer 31, this application can seal and shield the end of the electrode 21 exposed to the housing 10 in a close-fitting manner, preventing the leakage and condensation of the aerosol generation matrix or its volatile gases inside the housing 10 at the exposed end of the electrode 21. Even if the atomizer 1 is stored for a long time, there is no need to worry about the exposed end of the electrode 21 being contaminated.

[0039] When the atomizer 1 is needed, simply peel off the sealing layer 31 from the outer casing 10, assemble the atomizer 1 (with the sealing layer 31 removed) with the atomizing host, and electrically connect the exposed electrode 21 to the atomizing host. This allows for immediate use. This design avoids problems such as poor contact between the electrode 21 and the atomizing host, and eliminates the need for users to clean the exposed electrode 21 before assembly, thus improving the user experience.

[0040] exist Figure 1 In the illustrated embodiment, the outer casing 10 is generally in the shape of a flattened columnar structure. See also... Figure 2 and Figure 3It has an axis M. Its cross-section perpendicular to the axis M is approximately a flat rectangle, and along the extension direction of the axis M, the cross-sectional dimension of at least one end segment gradually decreases. The end with the gradually decreasing cross-sectional dimension can serve as the atomizing nozzle structure for user convenience.

[0041] In some other alternative embodiments, the outer shell 10 may also be configured as a cuboid, an elliptical column, a polygonal column, a cylinder, a racetrack-shaped column, an irregular shape, or other shapes.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 10 may include a housing 11 and a base 12, which are detachably connected and together define a chamber to form a storage cavity 13 that houses the atomizing assembly 20.

[0043] See also Figure 4 The base 12 has at least two clearance holes 121, corresponding to the number of electrodes 21. Each electrode 21 passes through one of the clearance holes 121, with one end electrically connected to the heating element 22 in the atomizing assembly 20, and the other end exposed on the end face of the base 12 facing away from the housing 11. The sealing layer 31 is detachably attached to the end face of the base 12 facing away from the housing 11, thereby sealing the exposed ends of the electrodes 21.

[0044] It should be understood that the base 12 and the main body 111 can be detachably connected by means of snap-fit ​​connection, bolt connection, interference fit, etc., without specific limitations.

[0045] In some other alternative embodiments, the electrode 21 may also be led out from the housing 11, in which case the sealing layer 31 may be detachably attached to the housing 11.

[0046] exist Figure 2 and Figure 3 In the embodiment shown, the end of the electrode 21 exposed on the base 12 is flush with the end face of the base 12 away from the housing 11, so that the sealing layer 31 can both seal the electrode 21 and achieve a relatively smooth surface-to-surface fit with the end face, thereby improving the sealing effect.

[0047] In some other alternative embodiments, the end of the electrode 21 exposed on the base 12 may protrude from the end face of the base 12 away from the housing 11, or be recessed within the clearance hole 121. When the exposed end of the electrode 21 is recessed within the clearance hole 121, the sealing layer 31 may only seal the end of the electrode 21. Alternatively, the sealing layer 31 may be configured as a three-dimensional structure, both conforming to the end face of the base 12 away from the housing 11 and having a portion extending into the clearance hole 121 to conform to the end of the electrode 21.

[0048] In some embodiments, the housing 11 may include a main body 111 and an air outlet 112. The main body 111 and the air outlet 112 are both cylindrical structures extending through both ends. The air outlet 112 is located inside the main body 111, and the hollow space extending through both ends can be considered as an air outlet channel 1121. One end of the air outlet 112 is connected to one end of the main body 111, such that the connected end has a closed portion, and the storage cavity 13 is located between the two.

[0049] exist Figure 2 and Figure 3 In the embodiment shown, the main body 111 and the air outlet 112 are integrally formed.

[0050] In some other alternative embodiments, the main body 111 and the air outlet 112 can also be connected by various connection methods such as threaded connection and snap-fit ​​connection.

[0051] It should be understood that the end where the main body 111 connects to the air outlet 112 can be regarded as the atomizing nozzle structure of the atomizer 1, for user use. The end of the air outlet channel 1121 corresponding to this end is the downstream end of the air outlet channel 1121.

[0052] In some other alternative embodiments, at least two of the main body 111, the air outlet 112, and the base 12 can be integrally molded. The housing 10 may also be specially provided with a suction nozzle structure for user suction, so that the housing 10 can be composed of one or more of the housing 11, the suction nozzle structure, the base 12, and other sealing or fixing components.

[0053] exist Figure 3 In the embodiment shown, the downstream end of the air outlet channel 1121 is... Figure 3 The upper part of the angle shown can also be called the top part.

[0054] exist Figures 1 to 3 In the illustrated embodiment, the main body 111 is generally flat and cylindrical, and the air outlet 112 is generally cylindrical.

[0055] In some other alternative embodiments, the air outlet 112 may also be flat, irregular, or other shapes, and its shape may be adapted to the main body 111 or may be set to different shapes from the main body 111.

[0056] like Figure 5As shown, in some embodiments, the air inlet 122 is defined by the base 12 and extends through both ends along the thickness direction of the base 12, approximately parallel to the axis M. When the sealing layer 31 is detachably attached to the end face of the base 12 away from the housing 11, the sealing layer 31 can also be opened to block the air inlet 122.

[0057] This design prevents leakage of the aerosol generation matrix or its volatile gases along the air inlet 122 during long-term storage of the atomizer 1. It further enhances the overall sealing of the atomizer 1, preventing the aerosol generation matrix from re-condensing on the surface of the electrode 21 and the outer surface of the outer shell 10, thus improving the overall cleanliness of the atomizer 1 and enhancing the user experience.

[0058] like Figure 4 As shown, in some embodiments, the electrode 21 includes an electrode post 211 and a connection end 212. The connection end 212 is disposed at the end of the electrode post 211 and is exposed outside the housing 10 for electrical connection with the atomizing host.

[0059] exist Figure 2 and Figure 3 In the illustrated embodiment, the electrode post 211 is longitudinally elongated, generally cylindrical, and extends parallel to the axis M. The connecting end 212 is generally flat and disc-shaped, coaxially arranged with the electrode post 211, and has a diameter larger than that of the electrode post 211 to provide a larger electrical connection area, facilitating a stable electrical connection. The clearance hole 121 can be configured with segments of different diameters.

[0060] Furthermore, the end face of the connection end 212 away from the electrode post 211 can be flush with the end face of the base 12 away from the housing 11.

[0061] In some other alternative embodiments, the connecting end 212 may also be in the form of a cylinder, a ball, a hemisphere, a polygonal block, a disc of various shapes, an irregular shape, or other shapes.

[0062] exist Figure 2 and Figure 3 In the embodiment shown, there are two electrodes 21, which are symmetrically arranged on both sides of the axis M. The air inlet 122 is located on one side of the axis M and is arranged approximately adjacent to one of the electrodes 21 to increase the curvature of the path from the air inlet 122 to the atomization channel 231, thereby reducing leakage of the aerosol generation matrix or its volatilized gas or condensate during the suction process from the air inlet 122.

[0063] In some other alternative embodiments, the air inlet 122 may also be located at the axis M of the base 12, coaxially arranged with the atomizing channel 231. The number of air inlets 122 may also be at least two. The air inlets 122 may also be located on the housing 11.

[0064] In some other alternative embodiments, the number of electrodes 21 may also be set to three, four, or other plurality of electrodes.

[0065] like Figure 2 and Figure 3 As shown, in some embodiments, the atomizing component 20 may further include an atomizing tube 23 disposed within the air outlet 112 and defining an atomizing channel 231. The heating element 22 is disposed within the atomizing tube 23.

[0066] Specifically, a step may be provided on the inner wall of the air outlet 112, the bottom end of the atomizing tube 23 is limited by the outer shell 10, and the top end is limited by the step of the air outlet 112, thereby realizing the limitation of the atomizing tube 23 within the outer shell 10.

[0067] It should be understood that, since part of the atomizing tube 23 is located inside the air outlet 112, the atomizing channel 231 defined by the atomizing tube 23 may partially overlap with the air outlet channel 1121 defined by the air outlet 112.

[0068] exist Figure 2 and Figure 3 In the embodiment shown, the main body 111, the air outlet 112, and the atomizing tube 23 are coaxially arranged.

[0069] like Figure 3 As shown, the atomizing tube 23 separates the storage chamber 13 from the atomizing channel 231. At least one liquid inlet hole 232 is also formed on the wall of the atomizing tube 23 so that the storage chamber 13 and the atomizing channel 231 are connected. The aerosol generating matrix in the storage chamber 13 can enter the atomizing channel 231 through the liquid inlet hole 232 and be heated and atomized by the heating element 22.

[0070] In some embodiments, the sealing layer 31 can be an electrostatic film capable of electrostatic adhesion, which can be repeatedly peeled and pasted, has strong adhesion, leaves no glue, and leaves no glue residue upon removal. The sealing layer 31 can also be various removable pressure-sensitive adhesive films, which also achieve the effect of leaving no glue residue after removal and provide a good sealing effect. The sealing layer 31 can also be a silicone protective film, which achieves stable sealing by coating with silicone, and also has stable peel force and leaves no glue residue. No specific limitations are made here.

[0071] Specifically, the sealing layer 31 can be made of materials such as PET, PP, PE, PVC, HIPS, ABS, PC, PS, etc.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments, the sealing layer 31 may include a sealing portion 311 and an operating portion 312. The sealing portion 311 is adapted to the end face of the base 12 facing away from the housing 11 to seal the entire end face of the base 12, and also seals the electrode 21 and the air inlet 122. The operating portion 312 is connected to one end of the sealing portion 311 and is used by the user to operate it; by pulling the operating portion 312, the sealing portion 311 can be torn off from the end face of the base 12.

[0073] exist Figure 4 and Figure 5 In the illustrated embodiment, the end face of the base 12 facing away from the housing 11, the sealing portion 311, and the operating portion 312 are all approximately rectangular in shape. The end face of the base 12 facing away from the housing 11 is the same size as the sealing portion 311, and chamfers are provided at the four corners of the rectangle. The operating portion 312 is smaller than the sealing portion 311 and is approximately a long rectangle to facilitate the user's picking up and tearing operation.

[0074] In some other alternative embodiments, the blocking part 311 and / or the operating part 312 may also be configured as other shapes such as circular, elliptical, racetrack-shaped, polygonal, or irregular. The blocking part 311 and the operating part 312 may also be configured as different shapes. The size of the operating part 312 may also be the same as that of the blocking part 311.

[0075] In some other alternative embodiments, the size of the sealing portion 311 may be smaller or larger than the end face of the base 12 facing away from the housing 11. The size and / or shape of the sealing portion 311 or the sealing layer 31 may also be adapted to the exposed end of the electrode 21. The shape of the sealing portion 311 may also be different from the shape of the end face of the base 12 facing away from the housing 11. The sealing layer 31 may also omit the operating portion 312.

[0076] It should be understood that the sealing part 311 and the operating part 312 can be integrally formed, and both are on the same plane in their natural state. Due to the properties of the material to which the sealing layer 31 is made, and the size setting of its layered structure, the sealing layer 31 can also undergo a certain degree of deformation (such as bending). Therefore, in some other optional embodiments, the sealing layer 31 can also be provided on a non-planar part of the outer shell 10.

[0077] In some embodiments, the protective component 30 may further include a protective sleeve 32, which is detachably fitted onto the outer casing 10, with the sealing layer 31 located between the protective sleeve 32 and the outer casing 10. The protective sleeve 32 protects the sealing layer 31 from accidental removal during storage. It also further seals the atomizer body, further reducing leakage of the aerosol generation matrix or its volatile gases through the gap between the air inlet 122 and / or the electrode 21 and the clearance hole 121.

[0078] Furthermore, such as Figure 4 and Figure 5 As shown, the protective sleeve 32 may include a bottom wall 321 and a side wall 322. The side wall 322 is cylindrical and detachably fitted onto the outer casing 10, with one end surrounding the bottom wall 321 in the circumferential direction. At least a portion of the sealing layer 31 is located between the bottom wall 321 and the outer casing 10.

[0079] exist Figure 2 In the illustrated embodiment, when the protective sleeve 32 is fitted onto the outer casing 10, the sealing portion 311 is located between the bottom wall 321 and the base 12. At least a portion of the operating portion 312 is located between the side wall 322 and the outer casing 10 (a portion of the operating portion 312 may extend beyond the protective sleeve 32). When the protective sleeve 32 is removed, the user can tear off the sealing portion 311 through the operating portion 312.

[0080] In some embodiments, the sidewall 322 is detachably connected to one end of the main body 111 near the base 12. At least one limiting structure 3221 protrudes from the inner side of the sidewall 322. When the protective sleeve 32 is fitted onto the outer shell 10, the limiting structure 3221 is interference-fitted with the outer wall of the main body 111 to achieve assembly of the two.

[0081] It should be understood that the protective cover 32 can be made of silicone, rubber, polyester or other materials to have a certain degree of elasticity and achieve a detachable connection with the outer shell 10 through an interference fit.

[0082] exist Figure 4 In the illustrated embodiment, the limiting structure 3221 is annular and surrounds the inner wall surface of the side wall 322 in the circumferential direction. While serving a limiting function, it also acts as a sealing ring, providing a certain sealing effect and further reducing the outward volatilization of gases from the aerosol-generating matrix.

[0083] In some other alternative embodiments, the number of the annular limiting structures 3221 may be at least two, spaced apart along the extension direction of the axis M. The limiting structures 3221 may also be block-shaped, and the number may be one or more.

[0084] In some alternative embodiments, the limiting structure 3221 may be omitted, and a detachable connection may be achieved through other connection methods such as snap-fit ​​connection or bolt connection, with a sealing ring used to achieve a sealed connection between the two. In this embodiment, the protective sleeve 32 may also be made of a rigid material with inelastic properties.

[0085] like Figure 4 As shown, in some embodiments, at least two protrusions 3211 are formed on the side of the bottom wall 321 facing the side wall 322. When the protective sleeve 32 is fitted onto the outer casing 10, the protrusions 3211 can correspond to the electrodes 21 respectively, so as to abut against the electrodes 21.

[0086] The protrusion 3211 can sandwich at least part of the sealing layer 31 between the protective sleeve 32 and the exposed end of the electrode 21, further improving the fit and sealing between the sealing layer 31 and the exposed end of the electrode 21, and preventing the aerosol matrix from condensing on its surface.

[0087] exist Figure 4 In the embodiment shown, the protrusion 3211 is generally disc-shaped and its size is adapted to the size of the exposed end of the electrode 21.

[0088] In some other alternative embodiments, the protrusion 3211 can also be configured as a hemispherical, polygonal, irregular, or other shapes. The size of the protrusion 3211 can also be slightly smaller than the size of the exposed end of the electrode 21. When the number of electrodes 21 is three or more, the number of protrusions 3211 can also be correspondingly set to three or more.

[0089] It should be understood that when the outer shell 10 covered by the protective sleeve 32 includes the air inlet 122, the number of protrusions 3211 can be greater than the number of electrodes 21, with some protrusions 3211 corresponding to the air inlet 122. When the protective sleeve 32 is fitted onto the outer shell 10, the multiple protrusions 3211 can not only abut against the electrodes 21 but also abut against the air inlet 122, thereby improving the sealing of the air inlet 122, protecting the exposed end face of the electrodes 21 from contamination, and further reducing the leakage of aerosol generation matrix and its volatilized gases.

[0090] It should be understood that the bottom wall 321, side wall 322, limiting structure 3221, and protrusion 3211 can be integrally molded. The limiting structure 3221 and protrusion 3211 can also be fixed to the side wall 322 or bottom wall 321 by means of gluing, interference fit with connecting grooves, etc.

[0091] like Figure 2As shown, in some embodiments, the atomizer 1 may also include a liquid-absorbing element 33, which is disposed between the protective sleeve 32 and the sealing layer 31, for absorbing the aerosol-generating matrix leaked from the outer shell 10, thereby reducing the contamination area of ​​the outer shell 10.

[0092] It should be understood that the liquid-absorbing component 33 can be made of porous materials such as absorbent cotton (including natural cotton and / or synthetic cotton), ceramics, and glass fiber, without specific limitations. It can absorb liquid through the capillary action of porous materials.

[0093] exist Figure 4 and Figure 5 In the embodiment shown, the liquid-absorbing element 33 is generally sheet-shaped and its shape is adapted to the shape of the bottom wall 321 of the protective sleeve 32.

[0094] In some other alternative embodiments, the absorbent 33 can also be cylindrical and disposed between the sidewall 322 and the outer casing 10. The absorbent 33 can also be shaped to fit the protective sleeve 32, covering the bottom wall 321 and at least a portion of the inner wall surface of the sidewall 322. The absorbent 33 can also be annular and disposed circumferentially at the junction of the bottom wall 321 and the sidewall 322. When the absorbent 33 is plate-shaped, its size can be smaller than the size of the bottom wall 321, and its shape can also be different from the shape of the bottom wall 321.

[0095] like Figure 3 As shown, in some embodiments, the protection component 30 may further include a blocking member 34, which is detachably blocked in the air outlet channel 1121 and / or the atomizing channel 231.

[0096] The sealing element 34 can block the air outlet channel 1121 of the atomizer 1, preventing leakage of the aerosol generation matrix and its volatilized gases through the air outlet channel 1121.

[0097] exist Figure 4 and Figure 5 In the embodiment shown, the sealing member 34 is arranged in a longitudinal column shape and is detachably inserted into the air outlet channel 1121 and the atomization channel 231. Its bottom end abuts against the end face of the base 12 facing the housing 11, and its top end extends to the outside of the housing 10 to facilitate user disassembly and assembly.

[0098] The sealing element 34 may be provided with a sealing ring in the circumferential direction to achieve a sealed connection between the sealing element 34 and the air outlet channel 1121 and / or the atomizing channel 231.

[0099] When the sealing component 34 is applied to the atomizer body, which is coaxially arranged with the air outlet channel 1121, the atomization channel 231, and the air inlet 122, the sealing component 34 abuts against the end face of the base 12 facing the housing 11, and can also block the air inlet 122, thereby blocking both ends of the airflow channel of the atomizer 1, further reducing the leakage of the aerosol generation matrix and its volatile gases.

[0100] exist Figure 3 In the embodiment shown, since the atomizing tube 23 extends into the air outlet 112 and its top end is connected to the top end of the air outlet 112, the sealing ring of the sealing member 34 is sealed to the inner side of the top end of the atomizing tube 23.

[0101] In some other alternative embodiments, when the extension length of the atomizing tube 23 within the air outlet 112 is less than the length of the air outlet 112, the sealing ring of the sealing member 34 can also be sealingly connected to the inner side of the air outlet 112. At least two sealing rings can also be provided along the axis of the sealing member 34, with at least one sealing ring provided on the shaft segment corresponding to the atomizing tube 23 and on the shaft segment corresponding to the air outlet 112, respectively.

[0102] In some other alternative embodiments, the sealing element 34 may also be configured as a short plug-like structure, detachably disposed at the downstream end of the air outlet channel 1121. The sealing element 34 may also be configured as a sheet-like structure, detachably attached to the housing 10 and located at the downstream end of the air outlet channel 1121 to seal it.

[0103] It should be understood that the protective component 30 can also be set on atomizer bodies with other structures. Since there are too many structural components and shapes of atomizer bodies, it is difficult to exhaustively list all the structures in the aforementioned embodiments, so they will not be elaborated on here.

[0104] This application also provides an electronic atomizing device, which may include an atomizing host and the atomizer 1 in any of the foregoing embodiments.

[0105] The atomizing unit can be detachably connected to the atomizer 1 and electrically connected to the electrode 21 after assembly. The atomizing unit may include a battery that can power the atomizer 1 for atomization operations via the electrode 21.

[0106] During the assembly of the atomizing host and the atomizer 1, the protective cover 32 and the liquid suction element 33 can be removed from the outer shell 10, and the sealing layer 31 affixed to the outer shell 10 and the exposed end of the electrode 21 can be removed. The sealing element 34 can then be removed from the air outlet channel 1121 and / or the atomization channel 231. Further, the atomizing host and the atomizer 1 can be assembled, so that the atomizing host and the electrode 21 are electrically connected.

[0107] This application also provides an electronic atomizing device, which may include a packaging shell and the atomizer 1 in any of the foregoing embodiments. The packaging shell may define an atomizer receiving cavity, in which the atomizer 1 is received.

[0108] During use, users can unseal the packaging shell themselves and take out the atomizer 1 from the atomizer housing for use.

[0109] In some embodiments, the electronic atomizing device may further include at least one desiccant, which may be disposed within the atomizer housing cavity to provide a dry and stable housing environment for the atomizer 1.

[0110] In some embodiments, the packaging shell may further define a host housing cavity, and the electronic atomizing device may further include an atomizing host. The atomizing host is housed within the host housing cavity.

[0111] During use, the user can unpack the packaging shell, remove the atomizer 1 from the atomizer housing, and remove the atomizer unit from the main unit housing. Then, assemble the atomizer 1 with the atomizer unit so that the electrode 21 of the atomizer 1 is electrically connected to the atomizer unit for use.

[0112] It is important to understand that the atomizer housing and the atomizer main unit housing can be two separate chambers. They can also be two parts of a single, integrated chamber. Furthermore, they can be two interconnected chambers, for example, partially connected by through holes or slots. No specific limitations are made here.

[0113] In this embodiment, the number of desiccants can be at least two, with at least one desiccant disposed in both the atomizer housing cavity and the main unit housing cavity.

[0114] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0115] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. Therefore, any equivalent transformations and modifications made within the scope of the claims of this application should be covered by the claims of this application.
