Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizer and atomization device. Background Technology

[0002] Refillable cartridge atomizers typically consist of a power supply unit (battery rod) and an atomizer (cartridge) detachably connected to the power supply unit. The power supply unit provides power to the atomizer and controls its operation. Under the control of the power supply unit, the atomizer atomizes the stored atomizing matrix and generates an aerosol. In conventional refillable cartridge atomizers, the atomizer and power supply unit are paired with electrodes via pogo pins, and the detachable connection and cartridge replacement are achieved through magnets that mate with each other on the atomizer and power supply unit. In this type of refillable cartridge atomizer, the electrodes need to be riveted to the bottom shell of the atomizer, and the bottom shell also needs to be riveted to the magnets. This process is complex, the manufacturing cost is high, and this conductive connection structure occupies a large space, which is not conducive to the optimized layout of the atomizer and other components inside the power supply unit. Utility Model Content

[0003] This application provides an atomizer and atomizing device, solving the technical problems of existing cartridge-type atomizing devices, such as relatively complex processes, high manufacturing costs, and large space-consuming conductive connection structures, which are not conducive to the optimized layout of other components inside the atomizer and power supply unit. The atomizer provided by this application improves the integration and layout flexibility of the conductive structure between the atomizer and the power supply unit, facilitates the optimized layout of other components inside the atomizer and power supply unit, and is easy to manufacture.

[0004] To address the aforementioned technical problems, some embodiments of this application provide an atomizer, comprising: a housing assembly including a mating shell, one end of which has a contact portion; a liquid storage assembly disposed within the housing assembly for storing an atomizing matrix; an atomizing assembly disposed within the housing assembly and communicating with the liquid storage assembly via a liquid path for atomizing the atomizing matrix; and a first control board disposed within the housing assembly, the first control board having at least two electrode contacts configured to be electrically connected to the atomizing assembly, and the electrode contacts being exposed within electrode holes of the contact portion.

[0005] In some embodiments, the mating shell is a ferromagnetic metal shell; and / or, at least a portion of the structure of the contact portion is a ferromagnetic structure.

[0006] In some embodiments, the housing assembly further includes a first housing and a support, the support having a stepped structure, and the first housing and the mating shell being respectively disposed on both sides of the stepped structure.

[0007] In some embodiments, the atomizer further includes an atomizing channel, and the atomizing component is disposed within the atomizing channel;

[0008] The liquid storage assembly includes a liquid storage chamber and a replenishment chamber. The replenishment chamber is used to supply the atomizing matrix to the liquid storage chamber, and the atomizing channel is provided through the liquid storage chamber.

[0009] In some embodiments, the contact portion is provided with an air inlet, and the straight-line distance between the air inlet and the liquid storage tank is less than the straight-line distance between the air inlet and the liquid replenishment tank.

[0010] In some embodiments of this application, an atomizing device is provided, the atomizing device including a power supply body and an atomizer as described in any of the above, the power supply body including a flexible electrode post, the power supply body being detachably connected to the atomizer, and the electrode post being inserted into the electrode hole and electrically connected to the electrode contact.

[0011] In some embodiments, the mating shell is a ferromagnetic metal shell, and / or at least a portion of the contact portion has a ferromagnetic structure; the power supply body is provided with a mating magnet, and the atomizer and the power supply body are magnetically connected through the mating magnet.

[0012] In some embodiments, the contact portion has a first central axis along a first direction, and the power supply body has a second central axis along the first direction; the electrode holes are arranged on the contact portion along the first direction, and the electrode holes are located on one side of the first central axis; the mating magnets are arranged on the power supply body along the first direction, and the mating magnets are located on the second central axis or the mating magnets are centrally symmetrical about the second central axis.

[0013] In some embodiments, the mating magnet extends along a second direction to increase the magnetic contact area between the mating magnet and the atomizer in the second direction; wherein the second direction intersects the first direction.

[0014] In some embodiments, the power supply unit is provided with an air intake channel and an airflow sensor; the atomizer is provided with an independent atomization channel and a sensing airway; when the atomizer and the power supply unit are in a combined assembly state, the atomization channel is connected to the air intake channel, and the airflow sensor is connected to the sensing airway.

[0015] The atomizer provided in this application includes a housing assembly, a liquid storage assembly, an atomizing assembly, and a first control board.

The first control board is disposed within the housing assembly and has at least two electrode contacts, which are exposed within electrode holes in the contact portion. The electrode contacts are electrically connected to the atomizing assembly. When the atomizer is installed on a mating power supply unit, the atomizing assembly and the power supply unit can be electrically connected through the electrode contacts. Compared to conventional cartridge-type atomizers where the atomizer and power supply unit are paired with electrodes via pogopins, the atomizer in this application achieves electrical connection between the atomizer and the power supply unit through electrode contacts located on the first control board. This reduces the space occupied inside the atomizer, and the number and position of the electrode contacts on the first control board have greater adjustability. By adapting the layout of the relevant conductive lines on the first control board, reliable electrical connection between different positions and different electrode contacts and the atomizing components can be achieved. Furthermore, it adapts to the electrode layout on the power supply unit, significantly improving the integration and layout flexibility of the conductive structure between the atomizer and the power supply unit. This facilitates the optimized layout of other components inside the atomizer and the power supply unit, and also simplifies manufacturing. Attached Figure Description

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by their components, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0035] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the order of the steps or actions in the method description can be changed or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0036] Please see Figures 1 to 3 In some embodiments of this application, an atomizer 10 is provided, which includes a housing assembly 1, a liquid storage assembly 2, and an atomizing assembly 3 (e.g., Figure 2 As shown), the first control board 4 (as shown) Figure 2 and Figure 3 As shown in the diagram, the housing assembly 1 includes a mating shell 11, one end of which is provided with a contact portion 111. The contact portion 111 is configured to be used with a power supply unit 20 (such as...) that can be used with the atomizer 10. Figure 8 (As shown in the diagram) Phase contact.

[0037] The liquid storage component 2 is located inside the housing component 1 and is used to store the atomizing matrix.

[0038] The atomizing component 3 is located inside the housing component 1 and forms a liquid channel with the liquid storage component 2. It is used to atomize the atomizing matrix to generate an aerosol that can be inhaled by the user.

[0039] The first control board 4 is disposed within the housing assembly 1, and the first control board 4 is provided with at least two electrode contacts 41 (e.g., Figure 1 and Figure 3 As shown in the diagram, electrode contact 41 is configured to be electrically connected to atomizing assembly 3, and electrode contact 41 is exposed in electrode hole 112 of contact portion 111.

[0040] Electrode contacts 41 are electrically connected to the atomizing component 3. When the atomizer 10 is installed on the power supply unit 20, the atomizing component 3 and the power supply unit 20 can be electrically connected through the electrode contacts 41. Compared with the conventional cartridge-type atomizer device where the atomizer 10 and the power supply unit 20 are paired with electrodes via pogo pins, the atomizer 10 in this application achieves electrical connection with the power supply unit 20 through electrode contacts 41 set on the first control board 4. This occupies less internal space in the atomizer 10, and the number and position of electrode contacts 41 on the first control board 4 have a relatively larger adjustable range. By adapting the layout of the relevant conductive lines on the first control board 4, reliable electrical connection between different positions and different electrode contacts 41 and the atomizing component 3 can be achieved. Furthermore, it adapts to the electrode layout on the power supply unit 20, significantly improving the integration and layout flexibility of the conductive structure between the atomizer 10 and the power supply unit 20. This facilitates the optimized layout of other components inside the atomizer 10 and the power supply unit 20, and is also convenient for manufacturing.

[0041] Please see Figure 3 In some embodiments, the first control board 4 may be a PCB board, and the electrode contacts 41 may be formed on the side of the first control board 4 facing the contact portion 111 by etching. The electrode contacts 41 may be treated with gold plating to improve their conductivity. The number and position of the electrode contacts 41 may be adjusted according to the specific structure of the atomizing component 3 and the power supply body 20, and this application does not limit them in this regard.

[0042] In some embodiments, the mating shell 11 is a ferromagnetic metal shell, meaning that the entire mating shell 11 is made of ferromagnetic metal material. The ferromagnetic metal shell, on the one hand, strengthens the structural strength of the shell assembly 1, providing protection and preventing damage to the atomizer 10 caused by impacts; on the other hand, the ferromagnetic metal shell has magnetization properties and can be magnetically attracted by magnets (such as magnets or electromagnets). By setting the mating shell 11 of the atomizer 10 in this application as a ferromagnetic metal shell, the magnet riveted to the bottom of the atomizer 10 in traditional cartridge-type atomizers can be eliminated, significantly reducing the complexity of the manufacturing process of the atomizer 10, simplifying its structure, and helping to reduce production costs.

[0043] In some embodiments, at least a portion of the structure of the contact portion 111 can be configured as a ferromagnetic structure, meaning that other parts of the mating shell 11 can be made of non-ferromagnetic materials. The contact portion 111 is the part where the mating shell 11 contacts the power supply body 20. By configuring at least a portion of the structure of the contact portion 111 as a ferromagnetic structure, it can be ensured that at least a portion of the structure of the contact portion 111 can be attracted by the magnet provided on the power supply body 20, thereby realizing a detachable connection between the atomizer 10 and the power supply body 20. This eliminates the need for the magnet riveted to the bottom of the atomizer 10 in traditional cartridge-type atomizers, significantly reducing the complexity of the manufacturing process of the atomizer 10, simplifying the structure of the atomizer 10, and helping to reduce production costs.

[0044] Please see Figure 2 In some embodiments, the housing assembly 1 further includes a first housing 12 and a bracket 13, the bracket 13 having a stepped structure 131, and the first housing 12 and the mating housing 11 being respectively disposed on both sides of the stepped structure 131.

[0045] The bracket 13 can serve as an intermediate structure to assemble the first housing 12 and the mating housing 11 together. After assembly, the first housing 12 and the mating housing 11 are located on both sides of the stepped structure 131. The structure is simple and easy to assemble, which can improve the assembly efficiency of the atomizer 10 and further reduce the production cost of the atomizer 10.

[0046] Please see Figure 2 In some embodiments, the atomizer 10 further includes an atomization channel 101. The first housing 12 is provided with a mouthpiece 121 for the user to inhale, and an air outlet 122 for aerosol discharge is provided on the end face of the mouthpiece 121. The air outlet 122 is connected to the air outlet end of the atomization channel 101. The atomizing component 3 is disposed in the atomization channel 101, and the atomizing component 3 and the atomization channel 101 form an air passage communication, so that the airflow in the atomization channel 101 can flow through the atomizing component 3, carry out the aerosol generated by atomization, and be discharged from the air outlet 122 for the user to inhale.

[0047] The liquid storage component 2 includes a liquid storage tank 21 and a replenishment tank 22. The replenishment tank 22 is used to supply the atomizing matrix to the liquid storage tank 21. The atomizing channel 101 is provided through the liquid storage tank 21. The liquid storage tank 21 and the atomizing component 3 form a liquid path connection so that the atomizing matrix in the liquid storage tank 21 can be guided to the atomizing component 3. The aerosol generated after the atomizing matrix is ​​atomized by the atomizing component 3 is carried out of the outlet 122 by the airflow in the atomizing channel 101.

[0048] Both the liquid storage tank 21 and the replenishment tank 22 can store the atomizing matrix. In some embodiments, the replenishment tank 22 can have a relatively larger volume to store more atomizing matrix, thereby increasing the atomizing matrix storage capacity and extending the service life of the atomizer. The liquid storage tank 21 can have a relatively smaller volume to supply the atomizing matrix to the atomizing assembly 3 at any time, ensuring continuous and stable aerosol production.

[0049] The replenishment tank 22 can be designed as a detachable structure, so that the atomizing matrix in the replenishment tank 22 can be replaced after it is used up. Alternatively, the replenishment tank 22 can be separated and new atomizing matrix can be added to achieve the purpose of reuse, which can further extend the service life of the atomizer 10 and help reduce the user's operating costs.

[0050] Please see Figure 2 and Figure 4 In some embodiments, the atomizer 10 further includes a first sealing body 5, which is disposed between the bracket 13 and the mating shell 11. For example... Figure 4 As shown, the first sealing body 5 has a first groove 51 and a second groove 52 arranged opposite to each other. After the atomizer is assembled, the first groove 51 and the bracket 13 define a liquid storage chamber 21, and the second groove 52 and the mating shell 11 define a first receiving space 14 (e.g., Figure 2 As shown in the figure, the first control board 4 is disposed in the first receiving space 14, and the side of the first control board 4 having electrode contacts 41 is close to or in contact with the inner surface of the contact portion 111 of the mating shell 11.

[0051] The first sealing body 5 is also provided with a connecting hole 53 that passes through the first groove 51 and the second groove 52. The connecting hole 53 can be configured as a countersunk hole structure. The inner cavity of the connecting hole 53 forms part of the atomization channel 101.

[0052] Please see Figure 2 In some embodiments, the liquid storage component 2 further includes a liquid storage 23, which is contained in a liquid storage chamber 21. The liquid storage 23 connects the atomizing component 3 and the replenishment chamber 22. The atomizing matrix in the replenishment chamber 22 can first flow to the liquid storage 23 and then be guided by the liquid storage 23 to the atomizing component 3.

[0053] The liquid storage 23 can be made of a liquid-absorbing material with a porous structure (such as fiber cotton) so that a certain amount of atomizing matrix can be stored in the liquid storage 23 to meet the liquid supply requirements of the atomizing component 3 for a period of time, and to ensure that the atomizer 10 can be used normally during the replacement or replenishment of the atomizing matrix in the replenishment chamber 22.

[0054] Please see Figure 2 and Figure 5In some embodiments, the support 13 has a liquid guiding part 132 on one side exposed outside the first housing 12. The liquid guiding part 132 can be configured as a tubular structure, and the liquid guiding part 132 connects the liquid storage tank 21 with the external space.

[0055] The replenishment chamber 22 is installed between the bracket 13 and the first housing 12. The replenishment chamber 22 has a storage cavity 221 for storing the atomized matrix. One end of the replenishment chamber 22 has an outlet 222 that communicates with the storage cavity 221 (e.g., Figure 6 As shown in the figure, a valve assembly 24 is connected to the outlet 222. The valve assembly 24 is configured to control the opening and closing of the outlet 222 in order to control the discharge of the atomized matrix in the storage chamber 221.

[0056] When the replenishment tank 22 is separated, the valve assembly 24 automatically closes the outlet 222 to prevent the atomized matrix in the storage chamber 221 from being discharged (e.g., Figure 6 (As shown in the diagram). When the replenishment tank 22 is installed between the bracket 13 and the first housing 12, the liquid guiding part 132 is inserted into the liquid outlet 222 and acts on the valve assembly 24, causing the valve assembly 24 to open the liquid outlet 222 and connect the liquid storage chamber 221 and the liquid storage tank 21, so that the atomized matrix in the liquid storage chamber 221 can flow to the stored liquid 23 in the liquid storage tank 21 through the liquid guiding part 132.

[0057] Please see Figure 2 and Figure 6 In some embodiments, the replenishment tank 22 is provided with an extension structure 223 extending into the storage chamber 221, and the extension structure 223 connects the outlet 222 and the storage chamber 221.

[0058] Valve assembly 24 includes valve body 241, spring 242, and sealing ring 243. One end of valve body 241 is provided with valve head 2411 (e.g., for sealing ring 243) that can close the liquid outlet 222. Figure 6 As shown in the diagram, the other end of the valve body 241 is provided with a rod 2412 that extends movably outward from the extension structure 223 (as shown in the diagram). Figure 6 (As shown in the diagram). A sealing ring is installed on the outer peripheral wall of the valve head 2411 to seal the gap between the valve head 2411 and the inner wall of the outlet 222, preventing the atomized matrix in the liquid storage chamber 221 from leaking out through the gap between the valve head 2411 and the outlet 222 when the chamber is closed. The outer diameter of the rod 2412 is smaller than the inner diameter of the extension structure 223 so that a gap can be left between the rod 2412 and the inner wall of the extension structure 223 for the atomized matrix to pass through.

[0059] like Figure 6As shown, the end of the extension structure 223 away from the outlet 222 is provided with a telescopic port 2231 that communicates with the liquid storage chamber 221. The end of the rod 2412 extending out of the telescopic port 2231 is provided with at least one stop portion 2413. The stop portion 2413 can stop on the end face of the extension structure 223 to prevent the valve body 241 from detaching from the outlet 222 outward from the replenishment chamber 22. The inner wall of the extension structure 223 is provided with a stop step 2232. The valve head 2411 can stop on the stop step 2232 to prevent the valve body 241 from detaching from the extension structure 223 and entering the liquid storage chamber 221 inward.

[0060] The side wall of the extension structure 223 is also provided with at least one leakage port 2233 that connects the liquid storage chamber 221 and the liquid outlet 222. When the valve head 2411 moves to the area of ​​the leakage port 2233, the atomizing matrix in the liquid storage chamber 221 can flow to the liquid outlet 222 through the leakage port 2233 to realize the discharge of the atomizing matrix.

[0061] Spring 242 is sleeved on rod 2412, and the two ends of spring 242 elastically abut against the inner end face of valve head 2411 and extension structure 223 respectively. Under normal conditions, spring 242 uses its own elastic force to push valve body 241 towards the liquid outlet 222 until the stop part 2413 stops at the end face of extension structure 223, and the valve head 2411 closes the liquid outlet 222, preventing the atomized matrix in liquid storage chamber 221 from leaking out of liquid outlet 222 when the liquid replenishment chamber 22 is separated from the bracket 13 and the first housing 12.

[0062] Correspondingly, the periphery of the liquid guiding part 132 is provided with at least one pusher part 1321 protruding from one end of the valve head 2411 (e.g., Figure 5 As shown in the diagram, when the replenishment chamber 22 is installed between the bracket 13 and the first housing 12, the liquid guiding part 132 is inserted into the liquid outlet 222, and the pushing part 1321 overcomes the elastic force of the spring 242 to push the valve head 2411 to the area of ​​the leakage port 2233, so that the atomized matrix in the liquid storage chamber 221 can flow to the stored liquid 23 in the liquid storage chamber 21 through the leakage port 2233, the liquid outlet 222, and the liquid guiding part 132.

[0063] Please see Figure 2 In some embodiments, the first housing 12 is provided with an air guide pipe 123 arranged along the height direction of the atomizer 10. The air outlet end of the air guide pipe 123 is connected to the air outlet 122, and the air inlet end of the air guide pipe 123 is connected to the air outlet end of the atomizing component 3.

[0064] Please see Figure 2 and Figure 7The atomizing assembly 3 includes an atomizing tube 31, a first liquid guiding element 32, a second liquid guiding element 33, and a heating element 34. The air inlet end of the atomizing tube 31 is fixed to the connecting hole 53 of the first sealing body 5, and the air outlet end of the atomizing tube 31 is connected to the air inlet end of the air guiding pipe 123. At least one liquid inlet 311 is opened on the tube wall of the atomizing tube 31 near the connecting hole 53, and the liquid inlet 311 connects the inner cavity of the atomizing tube 31 to the external space. The inner cavity of the atomizing tube 31 forms part of the atomizing channel 101.

[0065] The first liquid guiding element 32 can be configured as a tubular structure, sleeved on the outside of the atomizing tube 31, and at least part of the inner wall structure of the first liquid guiding element 32 seals the liquid inlet 311 from the outside. One end of the first liquid guiding element 32 near the connecting hole 53 can be inserted into the storage liquid 23 to connect the first liquid guiding element 32 and the storage liquid 23, so that the atomizing matrix on the storage liquid 23 can be guided to the first liquid guiding element 32.

[0066] The second liquid guiding element 33 can also be configured as a tubular structure, and the second liquid guiding element 33 is provided with a through hole 331 along its axis (e.g. Figure 7 As shown in the diagram, the inner cavity of the through hole 331 forms part of the atomization channel 101. The second liquid guide 33 is housed within the atomization tube 31, and at least part of the outer wall structure of the second liquid guide 33 seals the inlet 311 from the inside, so that the atomization matrix on the first liquid guide 32 can be transferred and adsorbed onto the second liquid guide 33 through the inlet 311, and finally flow to the atomization surface of the second liquid guide 33 (i.e., the hole wall of the through hole 331).

[0067] The heating element 34 includes at least one heating part 341 (e.g., Figure 7 As shown in the diagram, the heating elements 341 can be configured to operate independently, thereby enabling different heating modes of the heating element 34. The heating element 341 can be configured as a wound arc-shaped structure, and the heating element 341 is housed in the through hole 331 of the second liquid guiding element 33, and the heating element 341 is embedded or attached to the atomizing surface of the second liquid guiding element 33.

[0068] During use, the atomizing matrix on the liquid storage 23 is first guided to the first liquid guide 32, and then transferred and adsorbed to the second liquid guide 33 through the liquid inlet 311. The atomizing matrix on the second liquid guide 33 finally flows to the atomizing surface, and is then heated and atomized by the heating part 341 of the heating element 34. The aerosol generated by atomization is carried by the airflow in the atomization channel 101 and discharged from the atomizing tube 31, the air guide tube 123, and the air outlet 122.

[0069] Please see Figure 3In some embodiments, the atomizer 10 further includes at least two atomizing electrodes 42. The atomizing electrodes 42 can be fixed to the side of the first control plate 4 facing away from the contact portion 111 by welding, and the atomizing electrodes 42 can be electrically connected to corresponding electrode contacts 41 through the first control plate 4. The number of atomizing electrodes 42 can be matched with the number of electrode pins.

[0070] After the atomizer 10 is assembled, the end of the atomizing electrode 42 facing away from the first control board 4 abuts against the corresponding electrode pin, so that the electrode contact 41 is electrically connected to the corresponding electrode pin through the atomizing electrode 42.

[0071] Please see Figure 3 In some embodiments, the electrode contacts 41 can be arranged along the width direction of the atomizer 10 on one side of the first control board 4. This layout allows the atomizing electrode 42 to abut against the corresponding electrode pin of the heating element 34 on one side of the housing assembly 1, optimizing the space occupied by the conductive connection structure inside the housing assembly 1 and facilitating the layout of other components inside the atomizer 10.

[0072] Please see Figure 1 and Figure 2 In some embodiments, the contact portion 111 is provided with an air inlet 113. The straight-line distance between the air inlet 113 and the liquid storage tank 21 is smaller than the straight-line distance between the air inlet 113 and the liquid replenishment tank 22, so that the airflow entering through the air inlet 113 can pass through the atomizing component 3 with a relatively shorter path, thereby shortening the suction path, realizing the rapid suction response of the atomizer, and effectively improving the sensitivity of the atomizer.

[0073] In some embodiments, the replenishment chamber 22 can be configured to be further away from the contact portion 111 than the storage chamber 21. When the atomizer 10 is placed vertically, the storage chamber 21 is located at the lower part of the replenishment chamber 22 in the direction of gravity, so that the atomizing matrix in the replenishment chamber 22 can automatically flow to the storage chamber 21 under the action of gravity, ensuring a continuous and stable supply of liquid to the atomizing component 3.

[0074] The air inlet 113 connects the external space of the housing 11 with the first receiving space 14. The air inlet end of the atomizing channel 101 is connected to the air inlet 113 through the first receiving space 14. When in use, the user inhales through the air outlet 122 on the mouthpiece 121, creating a negative pressure inside the atomizer 10. The airflow from outside the atomizer 10 flows into the first receiving space 14 through the air inlet 113, and then enters the atomizing channel 101 through the connecting hole 53. When the airflow in the atomizing channel 101 flows through the through hole 331, it carries out the aerosol generated on the atomizing surface of the second liquid guide 33. The aerosol is discharged through the atomizing tube 31, the air guide tube 123, and the air outlet 122 under the influence of the airflow for the user to inhale.

[0075] The air inlet 113 can be set to one or more, and this application does not limit it, as long as at least one air inlet 113 is connected to the atomizing channel 101.

[0076] Please see Figure 8 and Figure 9 In some embodiments of this application, an atomizing device is provided, which includes a power supply body 20 and an atomizer 10 as described above, wherein the power supply body 20 and the atomizer 10 are detachably connected.

[0077] The power supply unit 20 is equipped with a power supply module 6 (such as...) Figure 9 As shown in the figure, the power supply module 6 is used to supply power to the atomizing device. The power supply body 20 is provided with a number of power supply electrodes 71 that are electrically connected to the power supply module 6. The number and position of the power supply electrodes 71 are matched with the electrode contacts 41.

[0078] After the atomizer 10 is installed in the power supply body 20, the power supply electrodes 71 respectively abut against the corresponding electrode contacts 41 to realize the electrical connection between the heating element 34 in the atomizer 10 and the power supply module 6 in the power supply body 20, thereby supplying power to the heating element 34 through the power supply body 20.

[0079] Please see Figure 8 and Figure 9 In some embodiments, the mating shell 11 is a ferromagnetic metal shell, meaning that the entire mating shell 11 is made of ferromagnetic metal material. The ferromagnetic metal shell, on the one hand, strengthens the structural strength of the shell assembly 1, providing protection and preventing damage to the atomizer 10 caused by impacts; on the other hand, the ferromagnetic metal shell has magnetization properties and can be magnetically attracted by magnets (such as magnets or electromagnets). By setting the mating shell 11 to a ferromagnetic metal shell in the atomizer 10 of this application, the magnet riveted to the bottom of the atomizer 10 in traditional cartridge-type atomizers can be eliminated, significantly reducing the complexity of the manufacturing process of the atomizer 10, simplifying its structure, and helping to reduce production costs.

[0080] In some embodiments, at least a portion of the structure of the contact portion 111 may be configured as a ferromagnetic structure, meaning that other parts of the mating shell 11 may be made of a non-ferromagnetic material. The contact portion 111 is the part where the mating shell 11 contacts the power supply body 20. By configuring at least a portion of the structure of the contact portion 111 as a ferromagnetic structure, it can be ensured that at least a portion of the structure of the contact portion 111 can be attracted by the magnet provided on the power supply body 20, thereby achieving a detachable connection between the atomizer 10 and the power supply body 20. This eliminates the need for the magnet riveted to the bottom of the atomizer 10 in traditional cartridge-type atomizers, significantly reducing the complexity of the manufacturing process of the atomizer 10, simplifying the structure of the atomizer 10, and helping to reduce production costs.

[0081] Correspondingly, the power supply body 20 is provided with a mating magnet 8. The mating magnet 8 can be a magnet or an electromagnet, and there can be one or more mating magnets 8. This application does not limit the number of mating magnets 8. When the atomizer 10 is installed on the power supply body 20, the mating magnet 8 magnetically attracts and fixes the mating shell 11, thereby attracting and fixing the atomizer 10 to the power supply body 20. That is, the atomizer 10 and the power supply body 20 are magnetically connected by the mating magnet 8, which significantly improves the ease of installation and removal of the atomizer 10.

[0082] Please see Figure 8 and Figure 9 In some embodiments, the power supply body 20 is provided with a plug slot 201, at least a portion of the structure of the atomizer 10 can be inserted into the plug slot 201, and the contact portion 111 of the mating shell 11 is close to or in contact with the bottom surface of the plug slot 201, and the stepped structure 131 stops at least a portion of the structure of the plug slot 201.

[0083] In some embodiments, the replenishment tank 22 may be configured to engage with the insertion slot 201.

[0084] The end face of the mating magnet 8 can be set to expose the bottom surface of the insertion groove 201 so that when the mating shell 11 is inserted into the insertion groove 201, the mating shell 11 can be attracted and fixed by the mating magnet 8.

[0085] Please see Figure 1 and Figure 8 In some embodiments, the contact portion 111 has a first central axis A along a first direction (e.g., Figure 1 As shown in the diagram, the bottom surface of the plug slot 201 of the power supply body 20 has a second central axis B along the first direction (as shown in the diagram). Figure 8 and Figure 10 As shown in the diagram, when the atomizer 10 is installed on the power supply unit 20, the first central axis A and the second central axis B are parallel and opposite to each other. In this embodiment, the first direction is taken as the width direction of the atomizing device, as shown in the diagram. Figure 1 The left and right directions of the middle contact part 111.

[0086] Electrode holes 112 can be arranged along a first direction on the contact portion 111, and all electrode holes 112 are located on one side of the first central axis A (e.g., Figure 1 (as shown in the image).

[0087] The mating magnet 8 is staggered with the electrode hole 112 to prevent interference between them. In some embodiments, the mating magnet 8 may also be arranged along a first direction on the power supply body 20, and the mating magnet 8 is located on the second central axis B, so that the mating magnet 8 is positioned relatively centrally relative to the electrode hole 112 (e.g., Figure 8(as shown in the figure). In some embodiments, the cooperating magnet 8 is centrally symmetrical about the second central axis B to ensure the stability of the atomizer 10 when it is connected to the power supply unit 20.

[0088] The electrode hole 112 is located on one side of the first central axis A, which is beneficial to the optimized layout of other components inside the atomizer 10; the mating magnet 8 is located in a relatively central position or is centrally symmetrical about the second central axis B, so that the mating magnet 8 can more firmly adsorb and fix the mating shell 11, which significantly improves the connection stability and reliability between the atomizer 10 and the power supply body 20.

[0089] The end of the mating magnet 8 can be set to be exposed on the bottom surface of the insertion groove 201. The shape of the mating magnet 8 exposed on the bottom surface of the insertion groove 201 can be circular, elliptical, rectangular, irregular, etc. This application will not elaborate on them one by one. The end faces of multiple mating magnets 8 are distributed on the second central axis B of the bottom surface of the insertion groove 201 or are centrally symmetrical about the second central axis B.

[0090] Please see Figure 10 In some other embodiments, the mating magnet 8 can be configured to extend along the second direction to increase the magnetic contact area between the mating magnet 8 and the atomizer 10 in the second direction. The second direction intersects the first direction; it should be noted that the second direction and the first direction can be perpendicular to each other, or the first direction can intersect the second direction but not be perpendicular. In some embodiments, the second direction is taken as the thickness direction of the atomizing device, such as... Figure 10 The shape of the mating magnet 8 exposed on the bottom surface of the insertion slot 201 can also be strip-shaped, and the strip-shaped end face of each mating magnet 8 exposed on the bottom surface of the insertion slot 201 can extend along the second direction (i.e., the thickness direction of the power supply body 20). This design can significantly increase the magnetic attraction contact area between the mating magnet 8 and the mating shell 11 in the thickness direction of the atomizing device, further improving the connection stability and reliability between the atomizer 10 and the power supply body 20.

[0091] Please see Figure 1 In some embodiments, the contact portion 111 of the housing 11 is provided with two independent air inlets 113. For easy distinction, one of the air inlets 113 is defined as the first air inlet 1131, and the other air inlet 113 is defined as the second air inlet 1132.

[0092] Please see Figure 9 , Figures 11 to 12 In some embodiments, the power supply unit 20 is provided with an air intake channel 202 (e.g., Figure 9 (as shown) and airflow sensor 9 (as shown) Figure 11 and Figure 12(As shown in the diagram). The power supply unit 20 has a second receiving space 203, and one end of the power supply unit 20 has a main air inlet 204. The power supply module 6 and the airflow sensor 9 are disposed in the second receiving space 203. The air intake channel 202 can be independent of the second receiving space 203. The air intake end of the air intake channel 202 is connected to the main air inlet 204, and the air outlet end of the air intake channel 202 is connected to the first air inlet 1131.

[0093] Please see Figure 2 and Figure 11 The atomizer 10 is provided with independent atomization channels 101 (e.g., Figure 2 (as shown) and sensing airway 102 (as shown) Figure 11 As shown in the figure, the air outlet of the atomizing channel 101 is connected to the air outlet 122, and the air inlet of the atomizing channel 101 is connected to the first air inlet 1131 through the first receiving space 14.

[0094] Please see Figure 2 The nozzle part 121 is also provided with a sensing air outlet 124 on its end face. The air outlet of the sensing air passage 102 is connected to the sensing air outlet 124, and the air inlet of the sensing air passage 102 is connected to the second air inlet 1132 through the first receiving space 14.

[0095] Please see Figure 8 In some embodiments, the power supply body 20 is also provided with a sensing air hole 205, which is exposed on the bottom surface of the plug slot 201. The sensing air hole 205 is configured to connect the airflow sensor 9 and the second air inlet 1132.

[0096] When the atomizer 10 is installed on the power supply unit 20 and the atomizer 10 and the power supply unit 20 are in a combined assembly state, the atomization channel 101 is connected to the air intake channel 202 through the first air intake port 1131 (e.g., Figure 2 As shown in the diagram, the airflow sensor 9 is connected to the sensing air passage 102 via the sensing air port 205 and the second air inlet 1132 (as shown in the diagram). Figure 11 and Figure 12 (as shown in the image).

[0097] In some embodiments, the power supply unit 20 is further provided with a control module, which is electrically connected to the power supply module 6, the heating element 34, and the airflow sensor 9, and is used to control the operation of the atomizing device. The airflow sensor 9 is used to monitor the airflow changes in the sensing airway 102 and send an airflow sensing signal to the control module. The control module controls the operation of the heating element 34 according to the received airflow sensing signal.

[0098] The sensing airway 102 is set independently of the atomizing channel 101. The control module will only start the heating element 34 when the airflow sensor 9 detects that the air pressure change in the sensing airway 102 reaches the set threshold. This independent sensing airway 102 arrangement can avoid the heating element 34 from being falsely activated due to unexpected changes in the airflow in the atomizing channel 101, which is safer and helps to reduce the power consumption of the atomizing device.

[0099] Please see Figure 11 and Figure 12 In some embodiments, the power supply body 20 is further provided with a second control board 7, which is disposed in the second receiving space 203. The power supply electrode 71 can be fixed to the second control board 7 by welding. The power supply electrode 71 can be a pogopin, i.e., an elastic electrode post. The electrode post is inserted into the electrode hole 112 and electrically connected to the corresponding electrode contact 41. At least part of the elastic contact of the electrode post is located on the bottom surface of the insertion groove 201. After the power supply body 20 and the atomizer 10 are installed, the elastic contact of the power supply electrode 71 elastically abuts against the corresponding electrode contact 41.

[0100] Please see Figure 11 In some embodiments, the power supply unit 20 is further provided with a third control board 100, which is disposed in the second receiving space 203. The third control board 100 may be a PCB board. The control module may be integrated on the third control board 100.

[0101] Please see Figure 8 , Figure 9 and Figure 11 In some embodiments, the power supply body 20 is also provided with a control button 200. At least a portion of the structure of the control button 200 is exposed on the power supply body 20 to facilitate manual touch or pressing by the user. The control button 200 is electrically connected to the control module and can be used to control the on / off state of the atomizing device. Alternatively, the control button 200 can be configured to control the switching of the working mode of the heating element 34, etc. This application does not limit this.

[0102] Please see Figure 9 and Figure 11 In some embodiments, the power supply unit 20 is also provided with a display module 300. The display module 300 is electrically connected to the control module through the third control board 100, and the display part of the display module 300 is exposed on the power supply unit 20. The display module 300 can be configured to display the operating status information of the atomizing device so that the user can understand and grasp the status of the atomizing device in a timely manner.
