[0052] An embodiment of the present application provides an atomizer 100, as shown in the drawings. Figures 1-4 The atomizer 100 includes an atomizing body 10 and first and second containers 20a and 20b connectable to the atomizing body 10. The atomizing body 10 is provided with a first liquid storage cavity 11 for storing an atomizable liquid substrate. The first container 20a is provided with a second liquid storage cavity 21a, and the second container 20b is provided with a third liquid storage cavity 21b. The second and third liquid storage cavities 21a and 21b also store the atomizable liquid substrate. When the first and second containers 20a and 20b are connected to the atomizing body 10, the liquid substrate in the second and third liquid storage cavities 21a and 21b can be transferred to the first liquid storage cavity 11, thereby supplementing the liquid substrate in the first liquid storage cavity 11.

[0053] The first liquid storage cavity 11 is provided with a liquid storage member 12 for adsorbing and retaining the liquid substrate in the first liquid storage cavity 11. The liquid storage member 12 is formed with a through hole (not shown in the drawings) longitudinally penetrating the body of the liquid storage member 12. A first gas guide tube 16 is arranged in the through hole. The first gas guide tube 16 is provided with an atomizing assembly. The atomizing assembly includes a liquid guide member 13 and a heating element 14 combined on the liquid guide member 13. The liquid guide member 13 and the liquid storage member 12 are in contact with each other. Thus, the liquid storage member 12 can transfer the liquid substrate stored therein to the liquid guide member 13, and further to the heating element 14. The heating element 14 on the liquid guide member 13 can heat and atomize the liquid substrate to generate aerosol, and release the generated aerosol into the first gas guide tube 16. Thus, the aerosol can be transmitted through the first gas guide tube 16.

[0054] The liquid storage member 12 and the liquid guide member 13 are made of porous material, which can be any one of cotton fiber, non-woven fabric, glass fiber rope, porous glass or porous ceramic, so that the liquid storage member 12 and the liquid guide member 13 can absorb or conduct liquid matrix through the microporous structure or the gap inside. Correspondingly, the heating element 14 can be combined with the liquid guide member 13 by printing, deposition, sintering or physical assembly, or wound on the liquid guide member 13.

[0055] In the embodiment, the atomization assembly is heated by the heating element 14 to atomize the liquid matrix to generate aerosol, that is, the heating element 14 is used as an atomization element to atomize the liquid matrix to generate aerosol, and in other embodiments, the atomization assembly can also include an ultrasonic atomization element capable of generating ultrasonic waves and forming aerosol by high-frequency vibration, and the atomization assembly can also be other components capable of forming aerosol from the liquid matrix, and the type of the atomization assembly is not limited in the present application.

[0056] Please continue to refer to Figure 2 and Figure 4 , the atomization body 10 includes a main body part 111 defining the first liquid storage cavity 11, a gas guide part 15 extending longitudinally away from the first liquid storage cavity 11 from the main body part 111, the gas guide part 15 has a free end 151 and a fixed end 152 oppositely arranged along the extension direction thereof, the fixed end 152 is fixedly connected with the main body part 111, and the free end 151 is provided with an air outlet 1511 for the aerosol to escape from the atomizer 100, and the user can inhale the aerosol at the air outlet 1511, that is, the free end 151 is configured as a suction nozzle of the atomizer 100. The fixed end 152 is in communication with the air outlet of the first gas guide pipe 16, and the aerosol released in the first gas guide pipe 16 can be transmitted to the gas guide part 15 through the first gas guide pipe 16, and then the gas guide part 15 further transmits the aerosol to the suction nozzle, as shown in the aerosol transmission route R1 shown in Figure 4 .

[0057] As shown in Figure 5 , when the first container 20a and the second container 20b are connected with the atomization body 10, a first liquid guide channel R2 is established between the first container 20a and the atomization body 10 to conduct the liquid matrix in the second liquid storage cavity 21a to the first liquid storage cavity 11, and a second liquid guide channel R2 is established between the second container 20b and the atomization body 10 to conduct the liquid matrix in the third liquid storage cavity 21b to the first liquid storage cavity 11. Through the independent first liquid guide channel R2 and the second liquid guide channel R3, the liquid matrix can be supplemented to the first liquid storage cavity 11 at the same time, so as to increase the liquid volume of the liquid matrix supplemented to the first liquid storage cavity 11 in unit time.

[0058] The connection between the first container 20a and the second container 20b and the atomization main body 10 can be a non-removable connection or a removable connection. When a removable connection is adopted, the first container 20a and the second container 20b can be detached from the atomization main body 10 when the liquid substrate stored in the first container 20a and the second container 20b is consumed, and then new containers 20 can be replaced, so that the atomization main body 10 can be recycled.

[0059] When a non-removable connection is adopted, that is, the atomization main body 10 and the container 20 cannot be detached again after being connected for the first time, the first container 20a and the second container 20b need to be discarded together with the atomization main body 10 when the liquid substrate in the first container 20a and the second container 20b is consumed, at which time the atomization main body 10 cannot be recycled.

[0060] It should be noted that the atomizer 100 can also be connected with more containers, and each container can establish an independent liquid guide channel between the atomization main body 10; or a plurality of containers can be stacked on the basis of the first container 20a and the second container 20b, respectively. The stacked containers can first transfer the liquid substrate stored therein to the first container 20a and the second container 20b, and then transfer the liquid substrate to the first liquid storage cavity 11 through the first liquid guide channel R2 and the second liquid guide channel R3, respectively.

[0061] In this embodiment, the first container 20a and the second container 20b are connected to the atomization main body 10, and after the connection, the first container 20a and the second container 20b respectively supplement the liquid substrate to the first liquid storage cavity 11 through the first liquid guide channel R2 and the second liquid guide channel R3. The first container 20a and the second container 20b do not need to store too much liquid substrate, thereby avoiding the requirement of the existing regulations that the liquid storage capacity in a single container cannot exceed the specified liquid capacity.

[0062] In some embodiments, as shown in Figure 3 The first container 20a and the second container 20b are connected to the atomization main body 10 in a manner of surrounding the air guide part 15, which can make the structure layout of the atomizer 100 more compact, without the need to set the volume of the atomizer 100 too large, thereby realizing the increase of the liquid capacity of two containers on the basis of the limited volume of the atomizer 100.

[0063] Further in some embodiments, as shown in Figure 2 When the first container 20a and the second container 20b are connected to the atomization main body 10 in a manner of surrounding the air guide part 15, a through hole 210 is defined between the first container 20a and the second container 20b, and the air guide part 15 passes through the through hole 210 so as to expose the suction nozzle of the atomizer 100 for the user to suck.

[0064] In some embodiments, as shown in Figure 3 The first container 20a and the second container 20b are completely identical in shape, so that the first container 20a and the second container 20b can be replaced with each other, and are convenient to connect with the atomizing body 10 without distinguishing the first container 20a and the second container 20b when connecting. Moreover, the first container 20a and the second container 20b are completely identical in shape, and the mold cost can be saved, and only one set of mold is needed for the first container 20a and the second container 20b.

[0065] In some embodiments, as shown in Figure 2 , Figure 5 and Figure 6 The first container 20a and the second container 20b each include a first sealing member 22 for sealing the second liquid storage cavity 21a and the third liquid storage cavity 21b1, and a support member 23 for providing support to the first sealing member 22, the support member 23 is fixedly connected with the shell 24, and the support member 23 is provided with a third connecting portion for connecting with the atomizing body 10. In the embodiment, the third connecting portion is a clamping groove 232 provided on the support member 23, and correspondingly, a clamping buckle member adapted to the clamping groove 232 is provided on the atomizing body 10, so that the first container 20a and the second container 20b are connected with the atomizing body 10 by clamping buckle connection.

[0066] It is easy to understand that the third connecting portion can also be a clamping buckle member provided on the support member 23, and correspondingly, a clamping groove adapted to the clamping buckle member is provided on the atomizing body 10. Alternatively, other connection methods known to those skilled in the art such as magnetic attraction connection can also be used for connection.

[0067] The support member 23 is formed with a first liquid guide column 231a and a second liquid guide column 231b extending away from the second liquid storage cavity 21 and being hollow, and the atomizing body 10 further includes a second sealing member 17 for sealing the first liquid storage cavity 11, the second sealing member 17 is formed with two first liquid guide holes 171 communicating with the first liquid storage cavity 11, and the side walls of the first liquid guide column 231a and the second liquid guide column 231b are each provided with a second liquid guide hole 2311 and a liquid guide groove 2312 communicating with the second liquid guide hole 2311, when the first container 20a and the second container 20b are connected with the atomizing body 10, the first liquid guide column 231a and the second liquid guide column 231b are correspondingly inserted into the first liquid guide hole 171, and then the liquid matrix flowing into the first liquid guide column 231a and the second liquid guide column 231b further flows into the first liquid storage cavity 11 through the second liquid guide hole 2311 and the liquid guide groove 2312, thereby forming a complete first liquid guide channel R2 or a second liquid guide channel R3, that is, the first liquid guide column 231a and the second liquid guide column 231b define a part of the first liquid guide channel R2 or the second liquid guide channel R3.

[0068] In addition, by providing two liquid guide columns, the first liquid guide column 231a and the second liquid guide column 231b, one of the liquid guide columns can be used to provide a liquid supplement path, and the other liquid guide column can be used to provide an air supplement path, through which external air is guided into the liquid storage cavity of the container, thereby maintaining the air pressure balance in the liquid storage cavity of the container, and facilitating smooth inflow of the liquid matrix in the container into the first liquid storage cavity 11.

[0069] In some embodiments, the first container 20a and the second container 20b can be connected to each other, so that before the first container 20a and the second container 20b are connected to the atomizing body 10, the first container 20a and the second container 20b are first connected as an integrated container assembly, and after the first container 20a and the second container 20b are connected, the through hole 210 is defined, and then the container assembly is sleeved outside the air guide portion 15, and the air guide portion 15 passes through the through hole 210. In this way, the efficiency of assembling the first container 20a and the second container 20b with the atomizing body 10 can be improved.

[0070] Further in some embodiments, as shown in Figure 2 the cross-sectional shape of the through hole 210 is non-circular, and then the container assembly can only be sleeved outside the air guide portion 15 in a specific direction, that is, the direction of connecting the first container 20a and the second container 20b with the atomizing body 10 is limited in this way, so that after the first container 20a and the second container 20b are connected with the atomizing body 10, the liquid guide columns of the first container 20a and the second container 20b can be aligned and inserted into the first liquid guide hole 171 on the atomizing body 10. In this embodiment, the cross-sectional shape of the through hole 210 is preferably flat, and in other embodiments, the cross-sectional shape of the through hole 210 can also be oval.

[0071] In addition, in some embodiments, as shown in Figure 7 the first container 20a and the second container 20b each include a housing 24, the housing 24 has a first side 241 and a second side 242 oppositely arranged along the width direction, the first side 241 is provided with a clamping groove 2411, and the second side 242 is provided with a clamping portion 2421, so that the clamping portion 2421 of the second side 242 can be clamped into the clamping groove 2411 of the other container, and the clamping groove 2411 can receive the clamping portion 2421 on the other container, that is, the clamping groove 2411 and the clamping portion 2421 on one of the containers are used for clamping connection with the other container, and then the first container 20a and the second container 20b can be connected into a container assembly in this way.

[0072] Further in some embodiments, as shown in Figure 7As shown, the shell 24 also has a first end 243 and a second end 244 oppositely arranged along the length direction of the shell 24, and the outer surface of the shell 24 includes a first side surface 245 and a second side surface 246 extending between the first end 243 and the second end 244, the second side surface 246 is formed with a recessed portion 2461 recessed towards the first side surface 245, the recessed portion 2461 is used to define a part of the through hole 210, that is, the through hole 210 is formed by the recessed portion 2461 on the first container 20a and the second container 20b, and the clamping groove 2411 and the clamping portion 2421 are arranged on both sides of the recessed portion 2461, so that when the first container 20a and the second container 20b are connected into a container assembly through the clamping groove 2411 and the clamping portion 2421, the recessed portion 2461 between the first container 20a and the second container 20b can be enclosed to form the through hole 210.

[0073] As a specific example, as shown in Figure 7 on one side of the recessed portion 2461, the first side surface 245 is provided with a groove 2451 adjacent to the second side surface 246, and one of the clamping groove 2411 and the clamping portion 2421 is arranged in the groove 2451. On the other side of the recessed portion 2461, an extension wall 247 protruding from the second side surface 246 is formed on the first side surface 245, and the other of the clamping groove 2411 and the clamping portion 2421 is arranged on the extension wall 247.

[0074] In addition, in some embodiments, as shown in Figure 7 the width d1 of the groove 2451 is the same as the width d2 of the extension wall 247, so that when the first container 20a and the second container 20b are connected to each other, the extension wall 247 can exactly cover the groove 2451, that is, the extension wall 247 and the groove 2451 can be completely fitted, so as to maintain the appearance integrity of the atomizer 100, and improve the appearance of the atomizer 100.

[0075] It should be noted that in the above embodiments, the groove 2411 is used as the first connecting portion, and the clamping portion 2421 matched with the clamping groove 2411 is used as the second connecting portion to connect the first container 20a and the second container 20b, and in other embodiments, the first connecting portion and the second connecting portion can also be connected in other ways, for example, the first connecting portion and the second connecting portion can also be two magnetic members capable of magnetically attracting each other, and the first container 20a and the second container 20b are connected to each other by magnetic attraction of the magnetic members; or in some embodiments, the first connecting portion and the second connecting portion can also be connected by adhesive connection. The application does not limit the connection mode of the first connecting portion and the second connecting portion, as long as the first container 20a and the second container 20b can be connected into the above-mentioned container assembly through the first connecting portion and the second connecting portion.

[0076] In some embodiments, as shown in Figure 7 The first side 241 of the shell 24 is further provided with a positioning column 248, and the second side 242 of the shell 24 is provided with a positioning groove 249 matched with the positioning column 248. When the first container 20a and the second container 20b are connected to each other, the positioning column 248 of the first container 20a is inserted into the positioning groove 249 of the second container 20b, so that the first container 20a and the second container 20b can be positioned when connected to each other, facilitating the connection of the first container 20a and the second container 20b.

[0077] In some embodiments, as shown in Figure 4 The liquid absorbing member 18 can be one of cotton fiber, non-woven fabric, or glass fiber rope. The liquid absorbing member 18 is configured in a hollow tube shape, and a tubular body 19 for the aerosol to flow through is further arranged in the liquid absorbing member 18, so that the aerosol flows more smoothly in the air guide part 15. Since the high-temperature aerosol and the external cold air mixed in the air guide part 15 form condensate, the liquid absorbing member 18 made of fiber material can absorb the condensate, avoiding the user from inhaling the condensate when inhaling.

[0078] The tubular body 19 can be made of stainless steel, copper, aluminum, or glass, so that the surface of the tubular body 19 is relatively smooth, reducing the suction resistance when the user inhales.

[0079] As shown in Figures 8-11 An electronic atomization device 200 is also provided in an embodiment of the present application, which comprises the atomizer 100 of the above-mentioned embodiments and a power supply assembly 300 for providing power to the atomizer 100. The power supply assembly 300 has a first end 31 and a second end 32 arranged opposite along the length direction thereof. The first end 31 is provided with a receiving chamber 311 for receiving the atomizer 100. The atomizer 100 further comprises an electrode 110 electrically connected to the atomizing element, and at least a portion of the electrode 110 is exposed to the outer surface of the atomizer 100.

[0080] The power supply assembly 300 comprises a battery 33 and a main board (not shown in the figure). The battery 33 and the main board are electrically connected. The main board is provided with a controller of the electronic atomization device 200, so that when the atomizer 100 is received in the receiving chamber 311, the controller can control the battery 33 to provide the atomizing element with the power required for atomization.

[0081] The power supply assembly 300 further comprises an electric connection terminal 34 electrically connected with the main board, the electric connection terminal 34 is exposed in the accommodation chamber 311, and then when the atomizer 100 is accommodated in the accommodation chamber 311, the electric connection terminal 34 and the conductive electrode 110 of the atomizer 100 are correspondingly electrically connected, so that the power supply assembly 300 can provide the atomizer 100 with electric energy through the electric connection terminal 34 and the conductive electrode 110.

[0082] The end surface of the second end 32 of the power supply assembly 300 is further provided with a first air inlet hole 321 for providing external air to enter the airflow inlet of the electronic atomization device 200, and the power supply assembly 300 is further provided with an airflow outlet 3111 exposed in the accommodation chamber 311, and the external air can flow from the first air inlet hole 321 to the airflow outlet 3111 through the airflow channel inside the power supply assembly 300. At the same time, the second end surface 140 of the atomizer 100 opposite to the accommodation chamber 311 is provided with a second air inlet hole 130, which communicates with the atomization assembly of the atomizer 100. When the atomizer 100 is accommodated in the accommodation chamber 311, the electric connection terminal 34 and the conductive electrode 110 of the atomizer 100 are correspondingly electrically connected, and at the same time, the airflow outlet 3111 of the power supply assembly 300 and the second air inlet hole 130 of the atomizer 100 are also aligned. Therefore, when the user sucks on the air outlet 1511 of the atomizer 100, the external air enters the electronic atomization device 200 through the first air inlet hole 321, flows to the airflow outlet 3111 through the airflow channel in the power supply assembly 300, and then further enters the atomizer 100 through the second air inlet hole 130, and is transmitted to the atomization assembly through the airflow channel in the atomizer 100 to carry the aerosol generated after the atomization of the atomization assembly to the air outlet 1511.

[0083] In some embodiments, in order to diversify the functions of the electronic atomization device 200, the atomization element 14 in the atomizer 100 comprises a first atomization element 141 and a second atomization element 142, which are arranged in parallel along the flow direction of the aerosol, that is, along the direction of the arrow route R1 in the middle, and the first atomization element 141 and the second atomization element 142 can be combined on the liquid guide 13 in a parallel manner, so that the controller can control the power supply assembly 33 to simultaneously provide the first atomization element 141 and the second atomization element 142 with electric energy, so that the first atomization element 141 and the second atomization element 142 work at the same time to make the electronic atomization device 200 enter the burst mode, that is, the heating power of the electronic atomization device 200 is relatively large, the generated aerosol has a higher concentration, and the taste of the aerosol is relatively rich. Figure 4

[0084] ​And, since the first atomization element 141 and the second atomization element 142 are in parallel, the controller can also control the power supply component 300 to supply power to only one of the atomization elements, so that the electronic atomization device 200 enters the normal mode, that is, the heating power of the electronic atomization device 200 is relatively small, the aerosol concentration generated is relatively low, and the taste of the aerosol is relatively soft.

[0085] As shown in Figure 9 The electrodes of the atomizer 100 include the first positive electrode 110a and the first negative electrode 110b electrically connected to the first atomization element 141 and at least partially exposed to the outer surface of the atomizer 100, and the second positive electrode 110c and the second negative electrode 110d electrically connected to the second atomization element 142 and at least partially exposed to the outer surface of the atomizer 100. The atomizer 100 further includes an electrical connector 120 electrically connecting the first negative electrode 110b and the second negative electrode 110d, and the first negative electrode 110b and the second negative electrode 110d are symmetrically arranged about the longitudinal axis L1 of the atomizer 100, and the first positive electrode 110a and the second positive electrode 110c are also symmetrically arranged about the longitudinal axis L1 of the atomizer 100. The electrical connector 120 is made of a material with high electrical conductivity, and suitable materials can be any one of metal materials such as silver, copper or aluminum, or carbon-based materials such as graphite.

[0086] As shown in Figure 11 The electrical connection terminal 34 of the power supply component 300 includes the first electrical connection terminal 34a and the second electrical connection terminal 34b arranged at intervals, and the third electrical connection terminal 34c located between the first electrical connection terminal 34a and the second electrical connection terminal 34b, wherein the third electrical connection terminal 34c is electrically connected to the ground of the power supply component 300.

[0087] When the atomizer 100 is accommodated in the accommodation chamber 311 in the first direction, the first electrical connection terminal 34a and the first positive electrode 110a are electrically connected, the second electrical connection terminal 34b and the second positive electrode 110c are electrically connected, the third electrical connection terminal 34c and the first negative electrode 110b are electrically connected, and since the first negative electrode 110b and the second negative electrode 110d are connected by the electrical connector 120, the third electrical connection terminal 34c is also electrically connected to the second negative electrode 110d, thereby forming a current return loop between the first positive electrode 110a and the first negative electrode 110b, and the first atomization element can work normally, and a current loop can also be formed between the second positive electrode 110c and the second negative electrode 110d, and the second atomization element can also work normally.

[0088] When the atomizer 100 is accommodated in the accommodation chamber 311 in a second direction which is 180 degrees to the first direction, since the first positive electrode 110a and the second positive electrode 110c, and the first negative electrode 110b and the second negative electrode 110d are symmetrically arranged about the longitudinal axis L1 of the atomizer 100, at this time the first electric connection terminal 34 will rotate to electrically connect with the second positive electrode 110c, the second electric connection terminal 34b will rotate to electrically connect with the first positive electrode 110a, and the third electric connection terminal 34c will rotate to electrically connect with the second negative electrode 110d. Similarly, since the first negative electrode 110b and the second negative electrode 110d are electrically connected by the electric connection piece 120, the third electric connection terminal 34c is also electrically connected with the first negative electrode 110b, and thus current loops can be formed between the first positive electrode 110a and the first negative electrode 110b, and between the second positive electrode 110c and the second negative electrode 110d, and the first atomization element and the second atomization element can also work normally.

[0089] Further, in the above manner, no matter whether the atomizer 100 is accommodated in the accommodation chamber 311 in the first direction or in the second direction which is 180 degrees to the first direction, the power supply assembly 300 can provide electrical energy to the first atomization element and the second atomization element, and the user does not need to accommodate the atomizer 100 in the accommodation chamber 311 in a specific direction, thereby improving the user's experience.

[0090] In addition, as shown in Figure 16 , the atomization assembly further comprises a first electrode lead 1411 for electrically connecting the first atomization element 141 and the first positive electrode 110a, a second electrode lead 1421 for electrically connecting the second atomization element 142 and the second positive electrode 110c, and a third electrode lead 1412 for electrically connecting with the first negative electrode 110b, wherein the third electrode lead 1412 is a negative electrode lead common to the first atomization element 141 and the second atomization element 142, correspondingly, the first electrode lead 1411 is a positive electrode lead of the first atomization element 141, and the second electrode lead 1421 is a positive electrode lead of the second atomization element 142. Since the first negative electrode 110b and the second negative electrode 110d are electrically connected with each other by the electric connection piece 120, the third electrode lead 1412 is also electrically connected with the second negative electrode 110d, and generally the first electrode lead 1411, the second electrode lead 1421 and the third electrode lead 1412 are all arranged on the same side of the inner wall of the liquid guide 13, as shown in Figure 17 .

[0091] Continuing to refer to Figure 17For the convenience of electrical connection, the first positive electrode 110a, the second positive electrode 110c and the first negative electrode 110b are also arranged on the same side, and then the first electrode lead 1411, the second electrode lead 1421 and the third electrode lead 1412 can be conveniently extended downward to be electrically connected with the first positive electrode 110a, the second positive electrode 110c and the first negative electrode 110b, and the first negative electrode 110b and the second negative electrode 110d are electrically connected through the electrical connector 120, so that the third electrode lead 1412 can also be conveniently electrically connected with the second negative electrode 110d, thereby avoiding the third electrode lead 1412 being electrically connected with the second negative electrode 110d which is far away by bending.

[0092] In addition, it should be noted that in some embodiments, the electrical connector 120 can also be electrically connected between the first positive electrode 110a and the second positive electrode 110c, and at this time the third electrode lead 1412 is a positive electrode lead shared by the first atomization element 141 and the second atomization element 142.

[0093] In some embodiments, as shown in Figure 9 , the first positive electrode 110a and the second positive electrode 110c are arranged symmetrically about the connection line of the first negative electrode 110b and the second negative electrode 110d. Alternatively, the first negative electrode 110b and the second negative electrode 110d are arranged symmetrically about the connection line of the first positive electrode 110a and the second positive electrode 110c, so that the parts of the first positive electrode 110a and the second positive electrode 110c, and the first negative electrode 110b and the second negative electrode 110d exposed to the surface of the atomizer 100 are more symmetrically arranged, which can make the appearance of the atomizer 100 more beautiful.

[0094] Further in some embodiments, as shown in Figure 9 , the second air inlet hole 130 is arranged in the central region of the end face 140, and the air flow outlet 3111 of the power supply assembly 300 is also arranged in the central region of the accommodation chamber 311, and the first positive electrode 110a and the second positive electrode 110c, and the first negative electrode 110b and the second negative electrode 110d are uniformly arranged around the air inlet hole 130, which can further make the appearance of the atomizer 100 more beautiful, and on the other hand, it is easy to align the second air inlet hole 130 with the air flow outlet 311 when the atomizer 100 is accommodated in the accommodation chamber 311.

[0095] In some embodiments, as shown in Figure 12 and Figure 13As shown, the extension length of the first negative electrode 110b is greater than that of the second negative electrode 110d, and since the first negative electrode 110b and the third electrode lead 1412 are directly electrically connected, while the second negative electrode 110d is indirectly electrically connected to the third electrode lead 1412 through the electrical connector 120, the extension length of the first negative electrode 110b is set to be longer to facilitate electrical connection with the third electrode lead 1412, while the extension length of the second negative electrode 110d is set to be shorter to reduce the manufacturing cost of the second negative electrode 110d.

[0096] Of course, the extension length of the first negative electrode 110b can also be less than that of the second negative electrode 110d, and the second negative electrode 110d is electrically connected to the third electrode lead 1412, and only the longer one of the first negative electrode 110b and the second negative electrode 110d needs to be electrically connected to the third electrode lead 1412.

[0097] In some embodiments, as shown in Figure 12 and Figure 13 The electrical connector 120 is configured in a sheet shape, and the electrical connector 120 is provided with a first through hole 121 and a second through hole 122 spaced apart from each other, a portion of the first negative electrode 110b extends into the first through hole 121 and is in interference fit with the first through hole 121, and a portion of the second negative electrode 110d extends into the second through hole 122 and is in interference fit with the second through hole 122, so that on the one hand, the electrical connector 120 can be fixed in the atomizer 100 through the interference fit, and on the other hand, the first negative electrode 110b and the second negative electrode 110d are respectively kept in electrical connection with the electrical connector 120.

[0098] In some embodiments, as shown in Figure 12 and Figure 13 The electrical connector 120 is further provided with a third through hole 123, and the third through hole 123 is arranged opposite to the air inlet hole 130, so that external air can flow to the atomization assembly through the third through hole 123.

[0099] In some embodiments, as shown in Figure 13 The aperture of the third through hole 123 is greater than that of the air inlet hole 130, so that the air inlet hole 120 can be completely exposed through the third through hole 123 to avoid the electrical connector 120 blocking the external air when the external air flows through the third through hole 123.

[0100] Further in some embodiments, as shown in 13, the third through hole 123 is located between the first through hole 121 and the second through hole 122, so that the third through hole 123 can be linearly communicated to the atomization assembly, thereby reducing the resistance of the external air in the process of flowing to the atomization assembly.

[0101] In some embodiments, as shown inFigure 9 and Figure 11 As shown in FIG. 10, the end surface 140 of the atomizer 100 is provided with a first pair of magnetic members, including a first magnetic member 150a and a second magnetic member 150b, which are arranged in parallel, and the receiving chamber 311 is provided with a second pair of magnetic members, including a third magnetic member 311a and a fourth magnetic member 311b, which are arranged in parallel, and the cross section of the receiving chamber 311 is circular. When the atomizer 100 is received in the receiving chamber 311, the first pair of magnetic members and the second pair of magnetic members are magnetically attracted to each other. Due to the magnetic attraction between the first pair of magnetic members and the second pair of magnetic members, the atomizer 100 can only be received in the receiving chamber 311 in the first direction or the second direction which is 180 degrees to the first direction.

[0102] It should be noted that more atomizing elements can be arranged in parallel in the atomizer 100. For example, a third atomizing element can be added on the basis of the first atomizing element and the second atomizing element. Correspondingly, a third positive conductive electrode 100e and a third negative conductive electrode 100f which are electrically connected to the third atomizing element and at least partially exposed to the outer surface of the atomizer 100 need to be added in the atomizer 100. The third negative conductive electrode 100f is electrically connected to the electrical connecting member 120. At this time, the third conductive electrode 100e can be arranged along the direction of the longitudinal axis L1, while the second air inlet hole 130 can be arranged elsewhere, such as Figure 14 As shown in FIG. 11, in this way, when the atomizer 100 with three atomizing elements is received in the receiving chamber 311 in the first direction or the second direction which is 180 degrees to the first direction, the power supply assembly 300 can still provide power supply to the three atomizing elements. It can be easily understood that at this time, the power supply assembly 300 also needs to add one more electrical connecting terminal to be electrically connected to the third positive conductive electrode 100e.

[0103] In addition, a fourth atomizing element and a fifth atomizing element can be added on the basis of the first atomizing element and the second atomizing element. Correspondingly, a fourth positive conductive electrode 100g and a fourth negative conductive electrode 100h which are electrically connected to the fourth atomizing element and at least partially exposed to the outer surface of the atomizer 100, and a fifth positive conductive electrode 100i and a fifth negative conductive electrode 100j which are electrically connected to the fifth atomizing element and at least partially exposed to the outer surface of the atomizer 100 need to be added in the atomizer 100. The fourth negative conductive electrode 100h and the fifth negative conductive electrode 100j are both electrically connected to the electrical connecting member 120. The four positive conductive electrodes and the four negative conductive electrodes are both arranged symmetrically about the longitudinal axis L1 of the atomizer 100. The second air inlet hole 130 can still be arranged in the central region of the end surface 140, as shown in FIG. 12. Figure 15As shown, by this way, when the atomizer 100 with four atomizing elements is received into the receiving chamber 311 in the first direction or the second direction which is 180 degrees to the first direction, the power supply assembly 300 can also provide the four atomizing elements with electricity. It is easy to understand that at this time, the power supply assembly 300 also needs to increase two electric connection terminals to electrically connect with the fourth positive conductive electrode 100g and the fifth positive conductive electrode 100i. If more atomizing elements are to be added, the above-mentioned way can be followed according to whether the number of the added atomizing elements is odd or even.

[0104] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; under the idea of the present application, the technical features of the above examples or different examples can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for simplicity; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
