[0063] In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

[0064] The present application proposes an electronic atomization device for atomizing a liquid matrix to generate an aerosol.

[0065] One embodiment of the present application provides an electronic atomization device, which can be found in Figures 1 to 4 As shown, it includes a nebulizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply body 200 that supplies power to the nebulizer 100. Figures 1 to 4In the illustrated embodiment, the atomizer 100 and the power supply body 200 of the electronic atomization device are detachable relative to each other; an electronic atomization device having such an atomizer 100 and a power supply body 200 that are detachable relative to each other is, for example, a so-called "replaceable cartridge" electronic atomization device. Or in some other variations, the atomizer 100 and the power supply body 200 of the electronic atomization device are tightly wrapped and fixed by the outer shell component of the electronic atomization device, so that the atomizer 100 and the power supply body 200 cannot be detachable relative to each other from the inside of the outer shell component. An electronic atomization device having such an atomizer 100 and a power supply body 200 that are not detachable relative to each other is, for example, a so-called "integrated or disposable" electronic atomization device.

[0066] In an alternative embodiment, such as Figures 1 to 4 As shown, the power supply body 200 includes:

[0067] A first end 210 and a second end 220 facing each other in the longitudinal direction;

[0068] The housing 211 defines at least a portion of the outer surface of the power supply body 200;

[0069] The receiving cavity 212 has an opening located at or toward the first end 210 ; thus, during use, the atomizer 100 can be received in or removed from the receiving cavity 212 via the first end 210 .

[0070] for example Figures 1 to 4 As shown, the first end 210 of the power supply body 200 is arranged at an angle; accordingly, at least part of the outer shell of the atomizer 100 is also inclined; and thus, during use, the atomizer 100 can only be received in the receiving cavity 212 of the power supply body 200 in a predetermined direction.

[0071] When the atomizer 100 is received in the receiving cavity 212, at least a portion of the atomizer 100 is exposed outside the receiving cavity 212. Figure 3 As shown in FIG, the air outlet 111 of the atomizer 100 is exposed to and / or outside the power supply body 200 for the user to inhale.

[0072] In some embodiments, such as Figures 1 to 4 As shown, the electronic atomization device also includes:

[0073] The cap 300 is removably coupled to the first end 210 of the power supply body 200. Figures 1 to 4 As shown, when the cap 300 is coupled to the first end 210 of the power supply body 200, it can cover the exposed portion of the atomizer 100 exposed outside the receiving cavity 212. It is beneficial to keep the exposed portion of the atomizer 100 clean or hygienic when not in use.

[0074] In an embodiment, the receiving cavity 212 is arranged to extend longitudinally; when the cap 300 opens the receiving cavity 212, the atomizer 100 can be received in the receiving cavity 221 from outside the power supply body 200, or removed from the receiving cavity 221. Figure 4 When the user needs to inhale from the air outlet 111 of the atomizer 100, the user operates the cap 300 to remove it from the first end 210 of the power supply body 200. Figure 3 As shown by the middle arrow P1, the exposed portion of the atomizer 100 and / or the air outlet 111 is exposed for the user to inhale.

[0075] according to Figures 1 to 4 As shown, the power supply body 200 includes a front side 230 and a rear side 240 that are opposite to each other in the thickness direction. In use, the front side 230 is usually facing the user.

[0076] according to Figures 1 to 4 As shown, the power supply body 200 is also arranged with:

[0077] Display screen 260. Display screen 260, such as an LED display screen or an LCD display screen, is used to prompt or display relevant information about the electronic atomization device. For example, in some embodiments, the relevant information displayed on display screen 260 may include the current remaining power of the electronic atomization device. For another example, in some embodiments, the relevant information displayed on display screen 260 may include whether the electronic atomization device is charging or the charging current / power. For another example, in some embodiments, the relevant information displayed on display screen 260 may include the TPM value of the current puff action or the duration of the current puff action.

[0078] In an embodiment, the display screen 260 is exposed on the front side 230 . Thus, during use, the user can obtain information prompts of the display screen 260 through the front side 230 .

[0079] according to Figures 4 to 10 As shown, the atomizer 100 includes:

[0080] The proximal end 110 and the distal end 120 are opposite to each other in the longitudinal direction; in use, the proximal end 110 is the end close to the user for suction; the distal end 120 is the end received in the power supply body 200 .

[0081] The atomizer 100 further comprises:

[0082] Several components are disposed within an enclosure (which may be referred to as a housing). The overall design of the enclosure may vary, and the type or configuration of the enclosure, which may define the overall size and shape of the power supply body, may vary. Generally, the enclosure may be formed from a single, integral housing, or the enclosure may be formed from two or more separable bodies. Figures 4 to 10As shown, the housing can include one or more reusable components; in some examples, all or only a portion of the housing can be formed from a metal or alloy such as stainless steel, aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, and the like.

[0083] according to Figures 4 to 10 As shown, the housing of the atomizer 100 is configured to be flat. Specifically, the longitudinal length of the atomizer 100 is greater than the width, and the width is greater than the thickness.

[0084] The housing of the atomizer 100 comprises:

[0085] A first housing portion 11 and a second housing portion 12 connected in the longitudinal direction of the atomizer 100;

[0086] The first housing portion 11 is close to or defines a proximal end 110, and the second housing portion 12 is relatively closer to a distal end 120. The second housing portion 12 is open toward the distal end 120 for mounting various functional components into the housing of the atomizer 100.

[0087] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0088] The end cap 20 is coupled to the second housing portion 12 and closes the opening of the second housing portion 12 toward the distal end 120. After assembly, the distal end 120 is defined by the end cap 20. Furthermore, the end cap 20 and the outer shell of the nebulizer 100 together define the complete outer body of the nebulizer 100.

[0089] according to Figures 4 to 10 As shown, the first housing portion 11 forms or defines an air outlet 113 at the proximal end 110 for outputting aerosol. In an embodiment, the first housing portion 11 is arranged at an angle toward one side in the thickness direction of the atomizer 100. Specifically, when the atomizer 100 is received in the power supply body 200, the first housing portion 11 is exposed outside the power supply body 200 and is arranged curved or inclined toward the front side 230. This is advantageous for users to inhale from the front side 230.

[0090] In some embodiments, the atomizer 100 further comprises:

[0091] The liquid storage chamber 123 is used to store the liquid matrix. In an embodiment, the liquid storage chamber 123 is formed or defined in the second housing portion 12 .

[0092] In some embodiments, the second housing portion 12 is provided with a liquid injection port 121 on one side in the width direction of the atomizer 100 , for allowing a liquid injection device such as a syringe to inject liquid matrix into the liquid storage chamber 123 through the liquid injection port 121 .

[0093] In some embodiments, the atomizer 100 is further provided with a liquid injection plug 122, which closes or blocks the liquid injection port 121. The liquid injection plug 122 can be removed by a user to open the liquid injection port 121 for liquid injection operation.

[0094] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0095] A flexible sealing element 13 and a sealing base 19 are longitudinally spaced apart. A liquid storage chamber 123 is defined or disposed between the flexible sealing element 13 and the sealing base 19. The flexible sealing element 13 and the sealing base 19 are made of a flexible material such as silicone. In an embodiment, the liquid storage chamber 123 is formed or defined between the flexible sealing element 13 and the sealing base 19, and the flexible sealing element 13 and the sealing base 19 partially define the boundaries of the liquid storage chamber 123.

[0096] In this embodiment, the flexible sealing element 13 includes a first sealing portion 131 and a second sealing portion 132. The first sealing portion 131 is at least partially located between the first housing portion 11 and the second housing portion 12 and provides a seal. The first sealing portion 131 is used to seal the liquid storage chamber 123. The second sealing portion 132 at least partially extends into the liquid storage chamber 123.

[0097] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0098] The tubular element 15 extends longitudinally through the liquid storage chamber 123. After assembly, the tubular element 15 is longitudinally arranged between the flexible sealing element 13 and the sealing base 19. Specifically, a portion of the upper end of the tubular element 15 is inserted into the second sealing portion 132 of the flexible sealing element 13 and then installed; a portion of the lower end of the tubular element 15 is inserted into the sealing base 19 and then installed.

[0099] In an embodiment, the tubular element 15 is rigid, for example, the tubular element 15 is made of a rigid material such as metal or ceramic. A plurality of liquid through holes 151 are arranged on the wall of the tubular element 15 .

[0100] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0101] The atomizing assembly 16 is located in the tubular element 15 and is in fluid communication with the liquid storage chamber 123. The atomizing assembly 16 is used to absorb the liquid matrix and atomize it to generate an aerosol.

[0102] according to Figures 4 to 10 As shown, the atomizing assembly 16 includes a liquid guiding element 161 and a heating element 162 combined with the liquid guiding element 161 .

[0103] In some embodiments, the liquid-conducting element 161 is flexible, for example, made of flexible fibers such as cotton fibers, non-woven fabrics, or sponges; the liquid-conducting element 161 is configured to be tubular or cylindrical and arranged along the longitudinal direction of the atomizer 100; the liquid-conducting element 161 is coaxial with the tubular element 15 and is located inside the tubular element 15. Alternatively, in some other variations, the liquid-conducting element 161 may also include a rigid porous element, such as porous ceramics or porous glass. The outer surface of the liquid-conducting element 161 is in fluid communication with the liquid storage chamber 123, and the outer surface of the liquid-conducting element 161 is used to draw liquid matrix from the liquid storage chamber 123, such as Figure 7 and Figure 8 As shown by the arrow R1.

[0104] In an embodiment, the liquid conducting element 161 is retained in the tubular element 15 ; the liquid conducting element 161 absorbs the liquid matrix from the liquid storage chamber 123 through the liquid through-holes 151 on the tubular element 15 .

[0105] In some embodiments, the inner surface of the liquid-conducting element 161 in the radial direction is configured as an atomizing surface, which is combined with / fitted with / abutted against the heating element 162; and then, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 162 to generate an aerosol and release it. Figures 4 to 10 As shown, heating element 162 is arranged to extend longitudinally along liquid-conducting element 161 and is coaxially arranged with liquid-conducting element 161. In some optional embodiments, heating element 162 is a resistive heating mesh, a resistive heating coil, or the like. In this embodiment, heating element 162 is a heating element wound around a sheet or mesh-like substrate. Conductive leads are welded or arranged on heating element 162, and current is conducted through the conductive leads to heating element 162.

[0106] In some other variations of implementation, the heating element 162 may be combined with the liquid-conducting element 161 by printing, deposition, sintering or physical assembly. In some other variations of implementation, the liquid-conducting element 161 may have a plane or a curved surface for supporting the heating element 162, and the heating element 162 is formed on the plane or the curved surface of the liquid-conducting element 161 by mounting, printing, deposition or the like. Or in some other variations of implementation, the heating element 162 is a conductive track formed on the surface of the liquid-conducting element 161. In some other variations of implementation, the conductive track of the heating element 162 may be in the form of a printed circuit formed by printing. In some other variations of implementation, the heating element 162 is a patterned conductive track. In some other variations of implementation, the heating element 162 is planar. In some other variations of implementation, the heating element 162 is a conductive track that extends in a circuitous, meandering, reciprocating or bending manner.

[0107] In this embodiment, the sealing base 19 has a first accommodating cavity 191 and a second accommodating cavity 192 arranged in sequence. The first accommodating cavity 191 is adjacent to the liquid storage cavity 123 and is open toward the liquid storage cavity 123. The diameter of the second accommodating cavity 192 is smaller than that of the first accommodating cavity 191, forming a step between them. The tubular element 15 passes through the first accommodating cavity 191 and then extends into the second accommodating cavity 192. The atomizer assembly 16 is located within the tubular element 15 and the first accommodating cavity 191, avoiding the second accommodating cavity 192.

[0108] In an embodiment, the atomizer 100 further comprises:

[0109] The porous liquid-retaining element 14 is located within the first accommodating chamber 191 and is arranged around or encircling the tubular element 15. The liquid-retaining element 14 abuts against the step between the first accommodating chamber 191 and the second accommodating chamber 192, forming a stop. The porous liquid-retaining element 14 at least partially extends from the first accommodating chamber 191 into the liquid storage chamber 123, thereby receiving and retaining liquid matrix from the liquid storage chamber 123. During use, the liquid-conducting element 161 receives the liquid matrix from the liquid storage chamber 123 via the liquid-retaining element 14.

[0110] according to Figures 4 to 10 As shown, at least one liquid guide groove 193 is arranged on the end surface of the sealing base 19 facing the liquid storage chamber 123; the liquid guide groove 193 extends from the outer surface of the sealing base 19 to the first accommodating chamber 191. In use, the liquid guide groove 193 can guide the liquid medium on the end surface of the sealing base 19 toward the liquid retaining element 14.

[0111] In an embodiment, the porous liquid retaining element 14 is made of a flexible or rigid porous material or a fiber material; for example, the porous liquid retaining element 14 includes porous fiber cotton or sponge. Figures 4 to 10 As shown by the middle arrow R1 , the liquid matrix in the liquid storage chamber 123 is absorbed and retained by the liquid retaining element 14 , and then passes through the liquid through-holes 151 of the tubular element 15 and is delivered to the liquid guiding element 161 to be received.

[0112] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0113] An annular isolation element 17 is housed or positioned within the second housing cavity 192; isolation element 17 at least partially extends from the lower end of tubular element 15 into tubular element 15. In some embodiments, isolation element 17 is annular and has multiple, spaced-apart outer surfaces. During assembly, the two conductive leads connected to heating element 162 are constrained between different outer surfaces of isolation element 17 and tubular element 15, thereby preventing the two conductive leads connected to heating element 162 from abutting or contacting each other during assembly, thereby preventing problems such as short circuits.

[0114] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0115] The first circuit board 30 , such as a PCB board or an FPC board, is arranged substantially perpendicular to the longitudinal direction of the atomizer 100 . The first circuit board 30 is arranged between the sealing base 19 and the end cover 20 .

[0116] In the embodiment, a memory 31 is arranged on the first circuit board 30 ; the memory 31 is, for example, an EEPROM memory chip, a Flash memory chip, etc.

[0117] In some embodiments, the memory 31 may also store the taste information of the liquid matrix and the initial resistance value information of the heating element 162; the storage 31 may also store the product anti-counterfeiting information of the atomizer 100, such as at least one of the sales area identification code information, the manufacturer, the production address, and the production date.

[0118] In some embodiments, the memory 31 stores information about the remaining amount of the liquid matrix in the liquid storage chamber 123 , or information about the remaining puff duration or the remaining number of puffs of the atomizer 100 .

[0119] In some embodiments, the circuitry of the second circuit board 270 of the power supply body 200 can calculate the amount of liquid matrix consumed in the liquid storage chamber 123 during each puff by the user. Then, after each puff by the user, the circuitry of the second circuit board 270 of the power supply body 200 can calculate or update the remaining amount of liquid matrix stored in the memory 31 based on the amount of liquid matrix consumed during the current puff.

[0120] For example, in some embodiments, based on the correlation between the amount of liquid matrix consumed by the heating element 162 when vaporized and heated, and the heating power of the heating element 162, the circuit of the second circuit board 270 of the power supply body 200 calculates the amount of liquid matrix consumed in each puff of each user based on the power provided to the heating element 162; and then, after the user puffs, the remaining amount of liquid matrix in the liquid storage chamber 123 before puffing is subtracted from the amount of liquid matrix consumed by the user's current puffing to obtain the remaining amount of liquid matrix after puffing, and the remaining amount of liquid matrix stored in the memory 31 is updated based on the calculation result.

[0121] For example, in some other embodiments, for electronic atomization products with drug delivery functions, during each user's puff, the power supply body 200 provides power to the heating element 162 according to a predetermined energy, so that the same aerosol supply can be provided in each user's puff, thereby achieving quantitative drug delivery. For example, in some specific embodiments, during each user's puff, the power supply body 200 provides power to the heating element 162 according to an energy control of 25J, so that the heating element 162 produces substantially the same amount of aerosol in each user's puff, which is beneficial for enabling the electronic atomization device product to provide aerosol to the user according to a predetermined dose in each use. In this embodiment, the circuit of the second circuit board 270 of the power supply body 200 deducts the predetermined consumption dose from the remaining amount of the liquid matrix in the liquid storage chamber 123 before puffing according to the user's puffing action, and updates the remaining amount of the liquid matrix stored in the memory 31 according to the calculation result.

[0122] In some embodiments, the control program of the power supply body 200 further includes: when the amount of aerosol generated by the nebulizer 100 and provided to the user reaches a maximum predetermined amount within a predetermined time, the power supply to the nebulizer 100 is stopped. For example, if the electronic atomization device controls the amount of aerosol generated by the nebulizer 100 each day to be lower than the maximum predetermined amount, thereby exceeding the maximum drug delivery amount, the control program of the power supply body 200 determines the drug delivery amount provided to the user in a day based on the amount of liquid matrix stored in the memory 31 that decreases over the day. When the amount of liquid matrix stored in the reservoir 31 decreases over the day to reach the maximum predetermined amount, the power supply to the nebulizer 100 is stopped for that day.

[0123] In an embodiment, the memory 31 is arranged on a first side surface of the first circuit board 30 facing the proximal end 110 .

[0124] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0125] The first electrical contact 21 extends from the distal end 120 into the atomizer 100 . The first electrical contact 21 abuts against a second surface of the first circuit board 30 facing the distal end 120 , thereby being electrically connected to the first circuit board 30 .

[0126] When the atomizer 100 is received in the power supply body 200, the first electrical contact 21 and the third electrical contact 272 come into contact and conduct electricity, thereby establishing a conductive connection between the first circuit board 30 and the second circuit board 270 of the power supply body 200. This allows the circuit of the second circuit board 270 to read or obtain the information stored in the memory 31.

[0127] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0128] The second electrical contact 22 extends from the distal end 120 into the atomizer 100. The second electrical contact 22 penetrates the first circuit board 30 and extends at least partially into the sealing base 19. The conductive lead of the heating element 162 extends from the first accommodating cavity 191 of the sealing base 19 to the outside of the sealing base 19 and connects to the second electrical contact 22 to form an electrically conductive connection; the second electrical contact 22 then conducts current to the heating element 162.

[0129] When the atomizer 100 is received in the power supply body 200, the second electrical contact 22 and the fourth electrical contact 273 come into contact and conduct electricity, thereby establishing a conductive connection between the heating element 162 and the second circuit board 270. This allows the circuit of the second circuit board 270 to control the output of power to the heating element 162, causing the heating element 162 to heat the liquid substrate.

[0130] according to Figures 4 to 10 As shown, the atomizer 100 further includes:

[0131] The flexible support element 18 is arranged substantially perpendicular to the longitudinal direction of the atomizer 100. The support element 18 is arranged between the first circuit board 30 and the end cover 20 to provide a flexible buffer between the first circuit board 30 and the end cover 20 after assembly.

[0132] according to Figures 4 to 10 As shown by the middle arrow R2, the atomizer 100 further includes:

[0133] An air inlet 23 , disposed on the end cap 20 and / or the distal end 120 , for allowing air to enter the atomizer 100 ;

[0134] An air flow channel is formed or defined between the air inlet 23 and the air outlet 111 to provide a flow path for air to flow through the heating element 162 to the air outlet 111 , thereby outputting the aerosol to the air outlet 111 .

[0135] In this embodiment, the airflow channel is defined by multiple components. As indicated by arrow R2, external air enters through air inlet 23, passes through support element 18 and first circuit board 30, and enters sealed base 19. It then passes through isolation element 17 and atomizer assembly 16, carrying aerosol through flexible sealing element 13 before being output to air outlet 111. Flexible sealing element 13 and the through-holes in first housing portion 11 define a portion of the airflow channel.

[0136] In the exemplary embodiment, the first sealing portion 131 and the second sealing portion 132 of the flexible closure element 13 are arranged obliquely to each other.

[0137] In an embodiment, at least a portion of the air flow channel located in the first sealing portion 131 and / or the first housing portion 11 is arranged obliquely relative to the longitudinal direction of the atomizer 100. Figure 8 As shown, at least a portion of the airflow channel located in the first sealing portion 131 and / or the first housing portion 11 has an inclination angle α with respect to the longitudinal direction of the atomizer 100. In some embodiments, the inclination angle α is approximately between 10° and 45°.

[0138] Alternatively, in some embodiments, the first housing portion 11 is arranged obliquely relative to the longitudinal direction of the atomizer 100 ; the first housing portion 11 has an inclination angle α with the longitudinal direction of the atomizer 100 ; the inclination angle α is approximately between 10° and 45°.

[0139] according to Figures 4 to 10 As shown by the middle arrow R5, the atomizer 100 further defines:

[0140] The ventilation channel R5 connects the liquid storage chamber 123 with the air flow channel / external atmosphere, thereby balancing the pressure of the liquid storage chamber 123 and the outside.

[0141] Alternatively, the ventilation channel R5 is used to provide a channel path for air to enter the liquid storage chamber 123; so that when the negative pressure in the liquid storage chamber 123 exceeds a predetermined threshold due to the consumption of the liquid matrix, external air can enter the liquid storage chamber 123 to relieve the negative pressure in the liquid storage chamber 123.

[0142] according to Figures 4 to 10 As shown, the ventilation channel R5 is at least partially formed between the liquid retaining element 14 and the inner surface of the first accommodating cavity 191 of the sealing base 19. Specifically:

[0143] A ventilation groove 194 is arranged on the inner surface of the first accommodating chamber 191 of the sealing base 19; the ventilation groove extends from the end surface of the sealing base 19 facing the liquid storage chamber 123 to the second accommodating chamber 192. A ventilation channel is at least partially defined between the inner surface of the first accommodating chamber 191 and the liquid retaining element 14. The liquid retaining element 14 can absorb the liquid matrix in the ventilation channel, thereby advantageously maintaining the ventilation channel unobstructed.

[0144] The tubular element 15 also has a ventilation hole 152 disposed on its wall. The ventilation hole 152 is aligned with and communicates with the port of the ventilation groove 194 on the step between the second accommodating chamber 192 and the first accommodating chamber 191. During use, the ventilation hole 152 connects the airflow channel R2 with the ventilation groove 194, thereby allowing the liquid storage chamber 123 to communicate with the airflow channel or air inlet 23 via the ventilation channel R5. When the negative pressure within the liquid storage chamber 123 gradually increases, the ventilation channel R5 provides a path for air from the airflow channel or air inlet to enter the liquid storage chamber 123 from the ventilation hole 152 and the ventilation groove 194, thereby alleviating the negative pressure within the liquid storage chamber 123.

[0145] In the embodiment, the ventilation communication hole 152 avoids the liquid-conducting element 161 and the isolation element 17. The ventilation communication hole 152 is located between the liquid-conducting element 161 and the isolation element 17.

[0146] according to Figures 11 to 18 As shown, the power supply body 200 also includes:

[0147] Battery cell 271, for power supply;

[0148] A second circuit board 270 is provided with a circuit;

[0149] The rigid bracket 250 is located between the receiving cavity 212 and the second end 220 ; the bracket 250 is used to support and hold the battery cell 271 and the second circuit board 270 .

[0150] After assembly, the second circuit board 270 is mounted between the bracket 250 and the front side 230 , and the battery cells 271 are mounted between the bracket 250 and the back side 240 . The display screen 260 is located between the second circuit board 270 and the front side 230 .

[0151] according to Figures 11 to 18 As shown, the power supply body 200 also includes:

[0152] The third electrical contact 272 and the fourth electrical contact 273 are located between the second circuit board 270 and the receiving cavity 212 and are at least partially exposed in the receiving cavity 212. The third electrical contact 272 and the fourth electrical contact 273 are connected to the second circuit board 270 via conductive wires.

[0153] When the atomizer 100 is received in the receiving chamber 212, the first electrical contact 21 abuts against the third electrical contact 272 to establish a conductive connection between the first circuit board 30 and the second circuit board 270, and the second electrical contact 22 abuts against the fourth electrical contact 273 to establish a conductive connection between the heating element 162 and the second circuit board 270; the second circuit board 270 can obtain or modify the information stored in the memory 31, thereby controlling the output of power to the heating element 162.

[0154] according to Figures 11 to 18 As shown, the power supply body 200 also includes:

[0155] A vibration element 274, such as a vibration motor, is housed or retained on one side of the bracket 250 in the width direction. The vibration element 274 is located between the battery cell 271 and the receiving cavity 212. When a user inhales or when the atomizer 100 is received in the receiving cavity 212, the circuitry of the second circuit board 270 controls the vibration element 274 to vibrate to alert the user.

[0156] according to Figures 11 to 18 As shown, the power supply body 200 also includes:

[0157] The flexible sealing element 280 is generally annular in shape. The sealing element 280 is at least partially positioned between the bracket 250 and the receiving cavity 212, at least partially providing a seal between the bracket 250 and the housing 211. Furthermore, the sealing element 280 defines an inner bottom wall 214 of the receiving cavity 212. When the atomizer 100 is received in the receiving cavity 212 of the power supply body 200, the distal end 120 of the atomizer 100 abuts against the inner bottom wall 214 of the receiving cavity 212.

[0158] according to Figures 11 to 18 As shown, the sealing element 280 is arranged with an air intake connecting hole 281 on one side or both sides of the width; the bracket 250 has an air cavity 275 facing the receiving cavity 212; the bracket 250 is also arranged with an avoidance gap 276 opposite to the air intake connecting hole 281, thereby connecting the air intake connecting hole 281 with the air cavity 275.

[0159] according to Figures 11 to 18 As shown, an air inlet groove 213 is arranged on the inner surface of the housing 211; the air inlet groove 213 extends from the first end 210 of the housing 211 to the air inlet communication hole 281. Figures 11 to 18 As shown by the middle arrow R4, the air intake groove 213 and the air intake communication hole 281 jointly define an air intake passage for delivering air from the first end 210 to the air cavity 275. The air intake groove 213 defines an inlet at the end of the first end 210 for air to enter.

[0160] When the atomizer 100 is received in the receiving cavity 212 of the power supply body 200 and inhaled, the air intake passage provides an air intake path for external air to enter the atomizer 100. Specifically, when the user inhales, external air flows longitudinally from the first end 210 along the air intake groove 213 to the air intake communication hole 281, passes through the air intake communication hole 281 and the avoidance gap 276, and then enters the air cavity 275.

[0161] In an embodiment, a portion of the air inlet passage extends from the first end 210 to the second end 220 between the inner surface of the receiving cavity 212 and the atomizer 100 .

[0162] In this embodiment, a portion of the intake passage extends from the intake communication hole 281 into the interior of the bracket 250 along the width direction. Furthermore, the intake passage longitudinally spans the inner bottom wall 214 of the receiving cavity 212. Furthermore, a portion of the intake passage extends between the inner bottom wall 214 of the receiving cavity 212 and the battery cells 271 and passes through a portion of the bracket 250. The portion of the intake passage that passes through the bracket 250 communicates with the airflow sensor 276, enabling the airflow sensor 276 to sense the airflow in the intake passage, which is beneficial for improving sensing accuracy.

[0163] according to Figures 11 to 18 As shown, the bracket 250 is also provided with:

[0164] The sensor holder 251 is located on the surface of the bracket 250 facing the rear side 240 and is positioned between the air cavity 275 and the battery cell 271. The sensor holder 251 houses and holds an airflow sensor 276, such as a microphone or MEMS sensor, for sensing airflow through the bracket 250 during a user's inhalation. The circuitry of the second circuit board 270 controls the power output to the heating element 162 of the atomizer 100 based on the sensing results of the airflow sensor 276.

[0165] according to Figures 11 to 18 As shown, in the embodiment, a separation distance 252 is defined between the airflow sensor 276 and the sensor holding portion 251;

[0166] The bracket 250 is also provided with:

[0167] The sensing connection channel 253 extends longitudinally from the spacing distance 252 to the air cavity 275; and then the air flow sensor 276 is connected to the intake channel through the sensing connection channel 253, such as Figure 17 As shown by the arrow R3, the airflow sensor 276 senses the change in airflow when the user takes a puff.
