Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, and more specifically, to a power supply device and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are devices that convert aerosol matrix into aerosol. These devices consist of an atomizer and a power supply, which are detachably connected for easy replacement of the atomizer. However, when inhalation is paused, some aerosol accumulates in the negative pressure chamber between the atomizer and the power supply. Over time, this aerosol condenses, forming a large amount of condensate that accumulates in the negative pressure chamber. Simultaneously, the aerosol matrix in the atomizer may overflow due to poor sealing or design flaws, flowing into the negative pressure chamber of the power supply. Excessive accumulation of condensate and overflowing aerosol matrix can corrode the airflow sensor through the airflow channel, causing damage and malfunction. Furthermore, liquid may seep out onto the exterior of the power supply, contaminating the device surface, severely impacting user experience and even posing safety hazards.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0060] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0064] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0065] Combination Figures 1 to 4 As shown, in one or more embodiments, this application provides an electronic atomizing device, comprising: an atomizer 200 and a power supply device 100, wherein the power supply device 100 is detachably connected to the atomizer 200, thereby facilitating the replacement of the atomizer 200. Exemplarily, a negative pressure chamber 101 is formed between the power supply device 100 and the atomizer 200; the atomizer 200 has a mouthpiece 201, which has an air intake channel 202 connected to the negative pressure chamber 101; the atomizer 200 stores an aerosol matrix. The power supply device 100 has an airflow sensor 102, which, when the user inhales through the mouthpiece 201, causes the negative pressure chamber 101 to be in a low-pressure state, thereby activating the airflow sensor 102.

[0066] In related technologies, when the atomizer in an electronic atomizing device is paused, some aerosol accumulates in the negative pressure chamber between the atomizer and the power supply. After prolonged use, the aerosol condenses, forming a large amount of condensate that accumulates in the negative pressure chamber. Simultaneously, the aerosol matrix in the atomizer may overflow due to poor sealing or design flaws, flowing into the negative pressure chamber of the power supply. Excessive accumulation of condensate and overflowing aerosol matrix can corrode the airflow sensor through the airflow channel, causing damage and malfunction. Furthermore, liquid may seep out of the power supply, contaminating the device surface, severely impacting user experience and even posing safety hazards.

[0067] Therefore, this application also provides a power supply device 100 to solve the problems in the related art; the power supply device 100 provided in this application embodiment will be described in detail below with reference to the accompanying drawings.

[0068] For ease of description, the width direction of the power supply device 100 is defined as the XX direction, the length direction of the power supply device 100 is defined as the ZZ direction, and the thickness direction of the power supply device 100 is defined as the YY direction. The XX direction, YY direction, and ZZ direction are all perpendicular to each other.

[0069] Combination Figure 4 and Figure 15 As shown in the embodiment of this application, the power supply device 100 includes: a first bracket 103, a liquid-absorbing component 104, a conductive component, and a battery 105; the first bracket 103 includes a enclosure 106 and a partition 107, the enclosure 106 is connected to the partition 107, the enclosure 106 is arranged circumferentially around the partition 107, and the enclosure 106 and the partition 107 cooperate to form a receiving groove 108; the liquid-absorbing component 104 is disposed in the receiving groove 108; the conductive component passes through the partition 107 and is located in the receiving groove 108; the conductive component is electrically connected to the battery 105.

[0070] In this embodiment of the power supply device 100, a liquid suction component 104 is installed in a receiving groove 108 formed on the first bracket 103. When the power supply device 100 is connected to the atomizer 200, the liquid suction component 104 can absorb the condensate during use and the aerosol matrix that may leak from the atomizer 200. This reduces the possibility of condensate and aerosol matrix flowing everywhere, thus helping to ensure the integrity of the function of the power supply device 100, keep the appearance of the power supply device 100 clean, extend the service life of the power supply device 100 and the electronic atomization device, and improve the user experience.

[0071] Combination Figure 4 and Figure 5 As shown, in some embodiments, the partition 107 has a first through hole 109, into which the conductive component is inserted; the first support 103 is made of plastic, and the enclosure 106 is fixedly connected to the partition 107, which can be integrally formed using a molding process. The height of the enclosure 106 is greater than the thickness of the partition 107, facilitating the formation of a receiving groove 108, which is open; the height of the enclosure 106 and the thickness of the partition 107 are parallel to the length of the power supply device 100. The conductive component can achieve a contact-type electrical connection with the atomizer 200, thereby powering the atomizer 200. The conductive component passes through the partition 107 so that one end of the conductive component is electrically connected to the battery 105 and the other end is electrically connected to the atomizer 200. The liquid suction member 104 can be a block or plate structure. Figure 6 and Figure 7As shown, the liquid suction member 104 has a first surface 110 and a second surface 111 facing each other. The first surface 110 faces away from the partition 107, and the second surface 111 faces the partition 107. The distance between the first surface 110 and the second surface 111 is the thickness of the liquid suction member 104. The thickness direction of the liquid suction member 104 is parallel to the length direction of the power supply device 100.

[0072] See Figure 8 As shown, in some embodiments, the power supply device 100 further includes a magnetic element 113, which is disposed between the liquid-absorbing element 104 and the side of the partition 107 facing the receiving groove 108. The liquid-absorbing element 104 is detachably installed in the receiving groove 108, which facilitates the replacement of the liquid-absorbing element 104. When the liquid-absorbing element 104 is removed from the receiving groove 108, the magnetic element 113 is attracted by a magnet, which allows the magnetic element 113 to drive the liquid-absorbing movement, so that the liquid is removed from the receiving groove 108. This reduces the squeezing of the liquid-absorbing element 104, thereby reducing the possibility of liquid flowing out of the liquid-absorbing element 104. Exemplarily, the magnetic element 113 is a magnet or an iron sheet; the magnetic element 113 has a sheet-like structure; the shape of the magnetic element 113 is adapted to the shape of the liquid-absorbing element 104.

[0073] In some embodiments, the liquid-absorbing element 104 is made of organic cotton or non-woven fabric, and the conductive component includes two spaced-apart spring pins 114 inserted into the first through hole 109. Organic cotton has high liquid absorption and capillary action, thus it can quickly absorb condensate and aerosol matrix, reducing the possibility of both liquids flowing around. Non-woven fabric has low cost, which helps to reduce the overall manufacturing cost of the power supply device 100. The spring pins 114 in the conductive component can ensure a reliable electrical connection with the atomizer 200, reduce contact resistance, and ensure consistent current transmission; in addition, the spring pins 114 can withstand frequent disassembly and assembly, extending the service life of the power supply device 100. Furthermore, the spaced-apart arrangement between the two spring pins 114 can prevent accidental contact between the positive and negative electrodes, preventing short circuits that could cause equipment failure or safety hazards. It should be noted that in some other possible embodiments, the liquid-absorbing element 104 can also be made of sponge, cotton, or polyester fiber; and the surface of the spring pins 114 can also be plated with a silver layer, which can reduce corrosion and improve conductivity.

[0074] Combination Figure 5 and Figure 15As shown, in some embodiments, the power supply device 100 further includes a first magnet 115, which is fixedly connected to the first bracket 103; the first bracket 103 further includes a first isolation tube 116, which is disposed in the receiving groove 108, fixedly connected to the partition 107, and connected to the first through hole 109. A spring needle 114 is also inserted into the first isolation tube 116, and the length of the first isolation tube 116 is greater than the thickness of the liquid suction member 104. Inserting the spring needle 114 into the first isolation tube 116 can prevent the spring needle 114 from directly contacting the liquid in the liquid suction member 104. This physical isolation reduces the risk of corrosion and extends the life of the spring needle 114. The length of the first isolation tube 116 exceeds the thickness of the liquid suction member 104, ensuring that the first isolation tube 116 completely penetrates the liquid suction member 104. This prevents liquid leakage from the liquid suction member 104 to the non-contact area of ​​the spring needle 114 and reduces the possibility of liquid flowing into the first through hole 109 through the spring needle 114, thereby helping to ensure the electrical safety of the power supply device 100. The first magnet 115 can achieve a magnetic connection with the atomizer 200, thus ensuring a reliable electrical connection between the spring needle 114 and the atomizer 200. Furthermore, the first magnet 115 can achieve a detachable fixed connection between the atomizer 200 and the power supply device 100, facilitating the replacement of the atomizer 200 and improving the user experience.

[0075] For example, the length direction of the first isolation tube 116 is parallel to the length direction of the power supply device 100; the first isolation tube 116 and the partition 107 are integrally formed using a molding process. The first support 103 also includes a second isolation tube 117, in which the first magnet 115 is fixed. The second isolation tube is located in the receiving groove 108, and the second isolation tube 117 is fixedly connected to the partition 107. The length of the second isolation tube 117 is the same as the length of the first isolation tube 116, which helps to reduce the possibility of liquid in the liquid suction member 104 coming into contact with the first magnet 115, thereby helping to ensure the cleanliness of the atomizer 200. The second isolation tube 117 and the partition 107 are integrally formed using a molding process. Since the first isolation tube 116 and the second isolation tube 117 are disposed in the receiving groove 108, the shape of the liquid suction member 104 can match the shape of the remaining space in the receiving groove 108. There are two first isolation tubes 116 and two second isolation tubes 117, which are spaced apart. The outer surface of one first isolation tube 116 is fixedly connected to the outer surface of one second isolation tube 117, and the outer surface of the other first isolation tube 116 is fixedly connected to the outer surface of the other second isolation tube 117. The first isolation tubes 116 and the second isolation tubes 117 are distributed in the width direction of the power supply device 100.

[0076] Combination Figure 4, Figures 11 to 13 As shown, in some embodiments, the power supply device 100 further includes a packaging shell 118, which has a packaging cavity 119 and a first air passage 120. The first air passage 120 has an inlet end 121 and an outlet end 122. The inlet end 121 of the first air passage 120 is connected to the packaging cavity 119, and the airflow sensor 102 is disposed in the packaging cavity 119. The outlet end 122 of the first air passage 120 is connected to the receiving groove 108. After the atomizer 200 is connected to the power supply device 100, the space formed by the first surface 110 of the liquid suction member 104, the enclosure 106 and the atomizer 200 is a negative pressure cavity 101, so the negative pressure cavity 101 includes part of the space of the receiving groove 108.

[0077] Combination Figure 4 , Figures 11 to 13 As shown, in some embodiments, the encapsulation shell 118 has an adsorption surface 123 and a plurality of protrusions 124. The adsorption surface 123 is arranged at intervals relative to the airflow sensor 102. The plurality of protrusions 124 are fixed on the adsorption surface 123 and are located in the encapsulation cavity 119. In this way, even if some liquid enters the encapsulation cavity 119, the gaps or channels formed between the protrusions 124 can be used to trigger the capillary effect to adsorb the liquid, preventing the liquid from flowing freely, thereby facilitating the retention of the airflow sensor 102. The air inlet 121 of the first air channel 120 can be located at the midpoint of the distance between the adsorption surface 123 and the airflow sensor 102, or the air inlet 121 of the first air channel 120 can be close to the adsorption surface 123, thereby facilitating the adsorption of liquid by the protrusions 124 on the adsorption surface 123.

[0078] For example, multiple protrusions 124 are arranged in an array on the adsorption surface 123, and the cross-section of the protrusions 124 can be circular or elliptical. The protrusions 124 can be columnar or conical. It should be noted that in some other possible embodiments, the adsorption surface 123 can also have a honeycomb structure; absorbent cotton can also be provided in the encapsulation cavity 119.

[0079] Combination Figure 4 , Figures 16 to 18 As shown, in some embodiments, the power supply device 100 further includes an air inlet pipe 125. The air outlet 122 of the first air passage 120 is connected to the receiving groove 108 via the air inlet pipe 125. One end of the air inlet pipe 125 extends into the receiving groove 108, and the other end of the air inlet pipe 125 is inserted into the air outlet 122 of the first air passage 120. The air inlet pipe 125 enables the connection between the encapsulation shell 118 and the first support 103, ensuring the airtightness of the connection between the first air passage 120 and the receiving groove 108. This helps to ensure that the airflow sensor 102 can be activated, thereby improving the sensitivity of the airflow sensor 102.

[0080] Combination Figure 4 , Figures 16 to 18 As shown, in some embodiments, a second through hole 126 is provided on the partition 107, and the air inlet pipe 125 passes through the second through hole 126 so that one end of the air inlet pipe 125 is connected to the receiving groove 108; the first bracket 103 also includes an extension pipe 127, which is fixedly connected to the partition 107, and the lumen of the extension pipe 127 is connected to the second through hole 126. The extension pipe 127 is located in the receiving groove 108. In this way, the possibility of liquid flowing into the second through hole 126 can be reduced by using the extension pipe 127. For example, the extension tube 127 and the partition 107 are integrally formed by an integral molding process. One end of the extension tube 127 is connected to the partition 107, and there is a gap between the other end of the extension tube 127 and the side of the partition 107 facing the receiving groove 108. This makes the end face of the other end of the extension tube 127 higher than the side of the partition 107 facing the receiving groove 108, wherein the side of the partition 107 facing the receiving groove 108 is the bottom of the cavity of the receiving groove 108.

[0081] Combination Figures 16 to 18 As shown, in some embodiments, the air intake pipe 125 includes a pipe body 128 and a shielding cap 129. One end of the pipe body 128 extends into the receiving groove 108, and the shielding cap 129 is located in the receiving groove 108. The shielding cap 129 is fixedly connected to one end of the pipe body 128. The pipe body 128 has a plurality of spaced-apart first air outlets 150 circumferentially distributed. The first air outlets 150 are located close to the shielding cap 129. The other end of the pipe body 128 is inserted into the air outlet end 122 of the first air passage 120. The shielding cap 129 is conical or frustum-shaped. In this way, the shielding cap 129 can reduce the possibility of liquid flowing into the air intake pipe 125. For example, the liquid suction has a clearance space 130 to expose the shield cap 129 of the air intake pipe 125, thus facilitating gas flow; the pipe body 128 and the second through hole 126 and the extension pipe 127 can be interference-fitted; the air intake pipe 125 also includes a limiting wing 131, which is fixed to the outer peripheral surface of the pipe body 128; the limiting wing 131 is close to one end of the pipe body 128 and away from the opposite end of the pipe body 128. During assembly, the air intake pipe 125 is inserted into the extension pipe 127 from the receiving groove 108, passes through the second through hole 126, and then is inserted into the first air passage 120; due to the presence of the limiting wing 131, the length of the air intake pipe 125 inserted into the first air passage 120 can be limited. Since the shield cap 129 is conical or frustum-shaped, the shield cap 129 has a maximum diameter, which is greater than the outer diameter of the pipe body 128, thus reducing the possibility of liquid entering the first air outlet 150.

[0082] Combination Figure 14 , Figure 15 , Figure 19 and Figure 20As shown, in some embodiments, the power supply device 100 further includes a first housing 132, which is detachably connected to the first support 103. The first housing 132 has a first air inlet 151, and an annular air intake channel 153 is formed between the first housing 132 and the enclosure 106, with the first air inlet 151 communicating with the air intake channel 153. The enclosure 106 has a second air inlet 152, and the air intake channel 153 is connected to the receiving groove 108 through the second air inlet 152. The detachable connection between the first housing 132 and the first support 103 facilitates production and assembly, reducing manufacturing complexity; it also facilitates the disassembly and replacement of the liquid suction component 104. The annular design of the air intake channel 153 allows the airflow to be distributed circumferentially along the enclosure 106, reducing local airflow concentration or turbulence. For example, an air intake channel 153 is formed between the outer surface of the first housing 132 and the outer surface of the enclosure 106, and the inner surface of the enclosure 106 is the cavity wall of the receiving groove 108; there is one second air intake hole 152, which can accelerate the speed and flow rate of the airflow entering the receiving groove 108 and improve the activation sensitivity of the airflow sensor 102; the second air intake hole 152 and the air intake pipe 125 are distributed at intervals in the thickness direction of the power supply device 100; the second air intake hole 152 can be in the form of a notch, which can be opened directly at the edge of the enclosure 106, reducing the difficulty of processing. It is understood that the second air intake hole 152 can be a circular through hole or a rectangular through hole.

[0083] See Figure 15 As shown, in some embodiments, the angle between the axis of the first air inlet 151 and the axis of the second air inlet 152 is a right angle. This right-angle turn design helps to slow down the airflow velocity, reduce turbulence, and ensure that the airflow enters the receiving groove 108 evenly. For example, the axis of the first air inlet 151 is parallel to the width direction of the power supply device 100, and the axis of the second air inlet 152 is parallel to the thickness direction of the power supply device 100.

[0084] See Figure 15 As shown, in some embodiments, there are two first air inlets 151; the axes of the two first air inlets 151 are coaxially arranged. Because the air intake channel 153 is annularly designed, it supports multi-directional air intake (e.g., two first air inlets 151), maintaining airflow even if either first air inlet 151 is blocked by fingers or dirt, thus enhancing device reliability. For example, the first air inlet 151 can be a circular or elliptical through-hole.

[0085] Combination Figure 19 and Figure 20As shown, in some embodiments, one of the first housing 132 and the first bracket 103 has a first guide groove 133, and the other has a first guide rail 134. The length direction of the first guide groove 133 is parallel to the length direction of the power supply device 100, and the length direction of the first guide rail 134 is parallel to the length direction of the power supply device 100. The first guide groove 133 and the first guide rail 134 cooperate to enable the first housing 132 to move along the length direction of the power supply device 100, and restrict the movement of the first housing 132 in the thickness direction and the width direction of the power supply device 100. The constraint effect of the first guide groove 133 and the first guide rail 134 reduces the unintended movement of the first housing 132, that is, it enables the first housing 132 to move only along the length direction of the power supply device 100, reduces the risk of loosening, and extends the service life of the first housing 132 and the first bracket 103. For example, the first housing 132 has a first guide groove 133, and the first bracket 103 has a first guide rail 134. When the first guide rail 134 slides into the first guide groove 133, the first housing 132 cannot move relative to the first bracket 103 along the thickness and width directions of the power supply device 100. Both the first guide groove 133 and the first guide rail 134 have a certain length, which can reduce the possibility of the first housing 132 accidentally detaching from the first bracket 103 during normal use. There are two first guide grooves 133 and two first guide rails 134, and the two first guide grooves 133 and the two first guide rails 134 are arranged in a one-to-one correspondence. The two first guide grooves 133 are spaced apart in the width direction of the power supply device 100, and the two first guide rails 134 are spaced apart in the width direction of the power supply device 100.

[0086] It should be noted that in some other possible implementations, the first guide groove 133 may also be disposed on the first bracket 103, and the first guide rail 134 may be disposed on the first housing 132.

[0087] Combination Figure 19 and Figure 20As shown, in some embodiments, one of the first housing 132 and the first bracket 103 has a first locking platform 135, and the other has a first locking slot 136. The first locking platform 135 and the first locking slot 136 cooperate to restrict the movement of the first housing 132 relative to the first bracket 103 along the length direction of the power supply device 100, so that the first housing 132 and the first bracket 103 are detachably connected. Thus, when the first locking platform 135 is engaged in the first locking slot 136, a fixed connection can be achieved between the first housing 132 and the first bracket 103. When disassembly is required, simply pry the first housing 132 to disengage the first locking platform 135 from the first locking slot 136. For example, the first locking platform 135 is disposed on the first bracket 103, and the first locking slot 136 is disposed on the first housing 132. There are two first card slots 136 and two first card platforms 135. The two first card slots 136 and the two first card platforms 135 are arranged in a one-to-one correspondence. The two first card slots 136 are spaced apart in the width direction of the power supply device 100, and the two first card platforms 135 are spaced apart in the width direction of the power supply device 100.

[0088] See Figure 20 As shown, in some embodiments, the first card holder 135 may have a guide slope 137, which is not parallel to the length direction of the power supply device 100 and is not perpendicular to the length direction of the power supply device 100. In this way, the guide slope 137 facilitates the first card holder 135 to be inserted into the first card slot 136.

[0089] See Figure 21 As shown, in some embodiments, the first card holder 135 may have two guide ramps 137, which are angled together, i.e., not parallel. The guide ramps 137 are not parallel to the length direction of the power supply device 100, nor are they perpendicular to it. One guide ramp 137 facilitates the first card holder 135 engaging with the first card slot 136, while the other guide ramp 137 facilitates the first card holder 135 disengaging from the first card slot 136 when a force is applied to the first housing 132 along the length direction of the power supply device 100, thereby achieving separation between the first bracket 103 and the first housing 132.

[0090] It should be noted that in some other possible embodiments, the first card slot 136 may also be disposed on the first bracket 103, while the first card platform 135 may be disposed on the first outer shell 132. In other possible embodiments, when the first card platform 135 is disposed on the first bracket 103 and the first card slot 136 is disposed on the first outer shell 132, the first card slot 136 may be in the form of a through hole, which facilitates the application of force to the first card platform 135 through the through hole, thereby facilitating the separation between the first bracket 103 and the first outer shell 132.

[0091] See Figure 19 As shown, in some embodiments, the first outer shell 132 includes a cylinder 138 and a side plate 139, with the cylinder 138 and side plate 139 fixedly connected. The cylinder 138 is sleeved on the first bracket 103, and the cylinder 138 and the first bracket 103 cooperate to form an insertion cavity 155. The atomizer 200 is inserted into the insertion cavity 155 to achieve a detachable fixed connection between the atomizer 200 and the power supply device 100. For example, a first air inlet 151 is formed on the cylinder 138; a first slot 136 and a first guide groove 133 are provided on the side plate 139. The gap between the cylinder 138 and the enclosure 106 forms an air inlet channel 153. In order to improve the sealing between the cylinder 138 and the first bracket 103 after the cylinder 138 is sleeved on it, thereby ensuring the sealing of the negative pressure cavity 101, a first sealing ring 142 is sleeved on the first bracket 103.

[0092] See Figure 20 As shown, in some embodiments, the first support 103 further includes a main body 140, which is fixedly connected to the enclosure 106. The main body 140 has a device cavity 141, in which the battery 105 is located, and the encapsulation shell 118 is located. Exemplarily, a first sealing ring 142 is sleeved on the main body 140, and a cylindrical body 138 is sleeved on the main body 140. A first mounting plate 135 and a first guide rail 134 are disposed on the main body 140.

[0093] Combination Figure 1 , Figure 4 and Figure 10As shown, in some embodiments, the power supply device 100 further includes a display screen 143 and a circuit board 144. The display screen 143 is connected to the circuit board 144, and the battery 105 is electrically connected to the circuit board 144. The first bracket 103 has a light-transmitting area 145, and the display screen 143 and the light-transmitting area 145 are disposed opposite to each other. For example, the light-transmitting area 145 is disposed on the main body 140, and the light-transmitting area 145 and the side plate 139 are disposed at intervals relative to each other in the thickness direction of the power supply device 100. The light-transmitting area 145 is used to facilitate the user's observation of the content displayed on the display screen 143. The airflow sensor 102 is integrated on the circuit board 144, and the conductive components are integrated on the circuit board 144. The material of the light-transmitting area 145 of the main body 140 is made of a transparent material, which can be polycarbonate or acrylic. The power supply device 100 also includes a charging interface module 154, which is electrically connected to the circuit board 144. The battery 105 is a rechargeable battery, so the charging interface module 154 can be used to charge the battery 105. The charging interface module 154 can have an interface type of USB-A, USB-C, or Micro-USB.

[0094] See Figure 4 As shown, in some embodiments, the power supply device 100 further includes a second bracket 146 located in the device cavity 141, and the circuit board 144, the display screen 143 and the battery 105 are respectively mounted on the second bracket 146.

[0095] See Figure 3 As shown, in some embodiments, the power supply device 100 further includes a first bottom cover 148 and a first bottom shell 149; the first bottom cover 148 is inserted into and fixedly connected to the main body 140 by a snap-fit ​​method. The first bottom cover 148 and the first bottom shell 149 can be fixedly connected by adhesive bonding. It should be noted that in some other possible embodiments, the first bottom cover 148 and the first bottom shell 149 can also be formed into an integral structure by an integral molding process. The first bottom cover 148, the first bottom shell 149, the side plate 139, and the main body 140 cooperate to realize that the device cavity 141 is in a closed form, which is beneficial for dust prevention.

[0096] Combination Figures 21 to 24 As shown, in some embodiments, the atomizer 200 further includes a base 203, a conductive electrode 204, and an atomizing core 205; the mouthpiece 201 is fixedly connected to the base 203, and the mouthpiece 201 also has a first liquid storage chamber 206 for storing the aerosol matrix; the base 203 has an air inlet chamber 211; the air inlet chamber 211 is connected to the negative pressure chamber 101, and the air inlet chamber 211 is also connected to the inhalation channel 202; combined with Figure 9 and Figure 10As shown, the conductive electrode 204 is inserted through the base 203 and is in contact with the spring pin 114. The conductive electrode 204 is electrically connected to the atomizing core 205. The atomizing core 205 is used to heat the aerosol matrix in the first liquid storage chamber 206 to achieve atomization.

[0097] Combination Figures 21 to 24 As shown, in some embodiments, the atomizer 200 further includes a top cover 208 and a third support 209, the third support 209 being inserted into the top cover 208; the top cover 208 being snap-fitted into the base 203. The top cover 208 has a second liquid storage chamber 207, the upper end of which is connected to the first liquid storage chamber 206. The atomizing core 205 is located at the lower end of the second liquid storage chamber 207 to seal the lower end of the second liquid storage chamber 207. In this way, the aerosol matrix flowing from the first liquid storage chamber 206 into the second liquid storage chamber 207 can come into contact with the atomizing core 205. When the atomizing core 205 is energized, it facilitates the atomization of the aerosol matrix.

[0098] Combination Figures 21 to 24 As shown, in some embodiments, the atomizer 200 further includes a second bottom cover 210, which is inserted and fixed to the mouthpiece 201; the material of the second bottom cover 210 can be metal, such as iron or stainless steel; in this way, the first magnet 115 in the power supply device 100 can be attracted to the second bottom cover 210, thereby ensuring the stability of the connection between the atomizing core 205 and the power supply device 100.
