DETAILED DESCRIPTION

[0030] The following will combine the attached drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in the field without creative work fall within the protection scope of this application.

[0031] The mention of "embodiments" in this text means that the specific features, structures or characteristics described in combination with the embodiments can be included in at least one embodiment of this application. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] This application provides an atomizing device, which is a product that can heat the atomization substrate to atomize it and generate mist. The atomizing device provided in this application is disposable, that is, the atomizing device in the embodiments of this application does not need to be charged or have its liquid storage parts replaced. It is an atomizing device that can be discarded after one use, and it is more convenient to carry, easier to use, has more stable performance and can store more atomization substrate. The disassembly scheme described in the embodiments is mainly designed for the disassembly during the manufacturer's recycling process. Generally, it is neither recommended nor required for users to disassemble it by themselves.

[0033] In the current atomizing devices on the market, it is usually necessary to use wires to electrically connect electrical components such as circuit boards, batteries and airflow sensors in the atomizing devices. However, the wires in the current atomizing devices will occupy the space in the atomizing devices, and manual welding is often required in the production process of the atomizing devices, which is time-consuming and laborious. This application aims to provide an atomizing device that is easy to assemble and has a low cost to solve the above problems.

[0034] Please refer to Figure 1, Figure 2 and Figure 3. Figure 1 is a structural schematic diagram of an embodiment of the atomizing device in this application. Figure 2 is an exploded structural schematic diagram of an embodiment of the atomizing device in this application. Figure 3 is a structural schematic diagram of the housing in an embodiment of the atomizing device in this application.

[0035] In this embodiment, the atomizing device 500 can include a housing 510, an atomization assembly 520 and a power supply assembly 530.

[0036] Among them, the housing 510 has a first installation position 511 and a second installation position 512. In this embodiment, the first installation position 511 and the second installation position 512 are in the form of cavities.

[0037] The first installation position 511 and the second installation position 512 are arranged side by side. The first installation position 511 has an opening on one side, and the second installation position 512 has openings on both sides, that is, both ends of the second installation position 512 are through; in other embodiments, the second installation position 512 can also have an opening on one side. The openings of the first installation position 511 and the second installation position 512 are used for assembling other components of the atomizing device 500.

[0038] In this embodiment, the first installation position 511 is used for installing the atomization assembly 520, and the second installation position 512 is used for installing the battery 531 in the power supply assembly 530.

[0039] The atomization assembly 520 plays a role in storing and heating the atomization substrate in this embodiment. Usually, the atomization assembly is arranged in the first installation position 511. During operation, it heats the stored atomization substrate to atomize it into an aerosol for users to inhale.

[0040] The power supply assembly 530 stores electrical energy. The power supply assembly 530 is electrically connected to the atomization assembly 520, and the atomization assembly 520 operates under the power supply of the power supply assembly 530.

[0041] The power supply assembly 530 can include a battery 531 and a circuit board 532. The battery 531 is electrically connected to the circuit board 532. Optionally, the circuit board 532 can integrate electronic components such as resistors, capacitors and inductors. The circuit board 532 can also be provided with a control circuit to control the discharge of the battery 531. The circuit board 532 can be a PCB circuit board.

[0042] In this embodiment, the battery 531 is a single-sided dual-tab battery, that is, both the positive and negative electrodes of the battery 531 are located on the same side of the battery 531. For example, the battery 531 is a capacitor battery.

[0043] In some embodiments, the battery 531 includes a first electrode 5311 and a second electrode 5312. The first electrode 5311 and the second electrode 5312 are simultaneously located on the side of the battery 531 close to the circuit board 532. The first electrode 5311 and the second electrode 5312 are fixedly connected to the circuit board 532, so that the battery 531 is fixedly connected to the circuit board 532 through the first electrode 5311 and the second electrode 5312, and the battery 531 and the circuit board 532 form an integrated structure.

[0044] In this embodiment, the first electrode 5311 and the second electrode 5312 have a certain rigidity. Therefore, in addition to conducting electricity, the first electrode 5311 and the second electrode 5312 can also support, stabilize and position the battery 531.

[0045] Optionally, the first electrode 5311 and the second electrode 5312 are made of metals such as stainless steel, aluminum, aluminum alloy, and magnesium alloy.

[0046] In one embodiment, the battery 531 is arranged in the second installation position 512. Since the second installation position 512 is arranged side by side with the first installation position 511, the battery 531 and the atomization assembly 520 in the atomizing device 500 in this embodiment are also arranged side by side.

[0047] Taking the battery 531 as a capacitor battery as an example, the battery 531 has a certain rigidity. Compared with the soft-pack batteries widely used in the prior art, the capacitor battery has a neater appearance and is easier for structural layout and mechanical installation. Therefore, when the battery 531 is accommodated in the first installation position 511, the space reserved for the size fluctuation of the battery 531 is reduced, and the space utilization rate is improved. Meanwhile, in the same battery space, the battery 531 in this embodiment has a larger battery capacity compared with the soft-pack battery, which improves the energy density of the battery 531.

[0048] Since the circuit board 532 is fixedly connected to the battery 531, when the battery 531 is accommodated in the second installation position 512, the circuit board 532 is fixedly arranged on one side of the housing 510.

[0049] Referring to Figure 2, in an exemplary embodiment, the battery 531 is cylindrical. The battery 531 is perpendicular to the circuit board 532 and fixedly connected to the circuit board 532. When the circuit board 532 is placed in the second installation position 512, the circuit board 532 is horizontally arranged on the opening of the second installation position 512.

[0050] Since the power supply assembly 530 in this embodiment is not provided with wires, and the housing 510 is respectively provided with installation spaces for the atomization assembly 520 and the power supply assembly 530, during the production and assembly process of the atomizing device 500, the circuit board 532 and the first electrode 5311 and the second electrode 5312 of the battery 531 can be fixedly connected first to form an integrated power supply assembly 530, and then the atomization assembly 520 is installed in the first installation position 511 in turn, and the battery 531 of the power supply assembly 530 is installed in the second installation position 512 to complete the production and assembly of the atomizing device 500. Therefore, there is no need to weld wires during the production process of the atomizing device 500 in this embodiment, which makes the atomizing device in this embodiment suitable for automated assembly based on mechanical equipment and can significantly reduce the overall cost of the atomizing device.

[0051] Please refer to Figure 1 - Figure 5. Figure 4 is a structural schematic diagram of the section I - I' in the embodiment shown in Figure 1. Figure 5 is an exploded structural schematic diagram of the atomization assembly in an embodiment of the atomizing device in this application.

[0052] As can be seen from the description of the above embodiments, the atomization assembly 520 plays a role in storing and heating the atomization substrate in the embodiments of the atomizing device.

[0053] In some embodiments, the atomization assembly 520 includes a liquid storage part 521, an aerosol pipe 522, an atomization pipe 523, a liquid guide part 524, a heating element 525 and heating element pins 526.

[0054] In one embodiment, the atomization assembly 520 does not include a liquid storage part 521, and the liquid medium is stored in the cavity around the atomization pipe 523.

[0055] In one embodiment, the liquid storage part 521 is used for storing the atomization substrate. Optionally, the material of the liquid storage part 521 can be non-woven fabric, integral cotton or PLA fiber. The liquid storage part 521 has an excellent adsorption effect, and the atomization substrate is stored in the liquid storage part 521.

[0056] The liquid storage part 521 is provided with an atomization channel 5211. The aerosol pipe 522, the atomization pipe 523, the liquid guide part 524, the heating element 525 and part of the heating element pins 526 are arranged in the atomization channel 5211.

[0057] Among them, the aerosol pipe 522 and the atomization pipe 523 are connected. The aerosol pipe 522 is provided with a mist channel 5221, and the atomization pipe 523 is provided with an atomization space 5231. The atomization space 5231 is connected to the mist channel 5221. In this embodiment, both the atomization space 5231 and the mist channel 5221 are located in the atomization channel 5211.

[0058] The liquid guide part 524 is arranged in the atomization space 5231. The side wall of the atomization pipe 523 is provided with an opening. The liquid guide part 524 is in contact with and connected to the liquid storage part 521 through the opening on the side wall of the atomization pipe 523 in the atomization space 5231.

[0059] When the liquid guide part 524 is in contact with the liquid storage part 521, it can introduce the atomization substrate stored in the liquid storage part 521 into the atomization space 5231.

[0060] Optionally, the material of the liquid guide part 524 can be porous materials or fibrous materials, such as porous ceramics, cotton, non-woven fabric or PLA fiber, etc.

[0061] The liquid guide part 524 is also provided with a containing space 5241. When the liquid guide part 524 is arranged in the atomization space 5231 of the atomization pipe 523, the containing space 5241 is connected to the mist channel 5221.

[0062] The heating element 525 is connected to the liquid guide part 524. In this embodiment, the heating element 525 is arranged in the containing space 5241. The heating element 525 is used for generating heat. After the liquid guide part 524 introduces the atomization substrate stored in the liquid storage part 521 into the atomization space 5231, the heating element 525 can heat and atomize the atomization substrate in the atomization space 5231 to form an aerosol, and the aerosol can flow from the atomization space 5231 into the mist channel 5221.

[0063] Optionally, the heating element 525 can be a metal heating wire or a metal heating mesh.

[0064] Optionally, the aerosol pipe 522 and the atomization pipe 523 can be stainless steel pipes or glass fiber pipes. The stainless steel pipes or glass fiber pipes can absorb the aerosol generated by atomization, and can also separate the aerosol from the liquid storage part 521 to prevent the liquid storage part 521 from adsorbing the aerosol and affecting the taste of the aerosol.

[0065] The heating element pins 526 are arranged on the side of the heating element 525 away from the mist channel 5221. One end of the heating element pins 526 is electrically connected to the heating element 525, and the other end is electrically connected to the power supply assembly 530. The power supply assembly 530 provides the electrical energy required for the atomization work of the heating element 525 through the heating element pins 526.

[0066] Optionally, the number of heating element pins 526 is two, corresponding to the positive and negative poles of the power supply assembly respectively. In other embodiments, the number of heating element pins 526 can also be three or more.

[0067] During the production and assembly of the atomization assembly 520 in this embodiment, the liquid guide part 524, the heating element 525 and the heating element pins 526 can be connected together first and then installed into the atomization channel 5211 from the atomization channel 5211 together, and then the aerosol pipe 522 is installed into the atomization channel 5211 from the other side of the atomization channel 5211 to realize the integration of the atomization assembly 520 and facilitate the installation of the atomization assembly 520. Optionally, when the aerosol pipe 522 and the atomization pipe 523 are installed in the atomization channel 5211, they can be in interference fit with the side wall of the atomization channel 5211 to strengthen the fixation of the aerosol pipe 522 and the atomization pipe 523.

[0068] After the atomization assembly 520 is assembled, the liquid storage part 521 can be installed in the first installation position 511. The aerosol pipe 522, the atomization pipe 523, the liquid guide part 524, the heating element 525 and the heating element pins 526 are installed in the first installation position 511 together with the liquid storage part 521. Therefore, the atomization assembly 520 in the atomizing device 500 in this embodiment is easy to install and facilitates the realization of the automation of the installation of the atomizing device 500.

[0069] Please refer to Figure 2, Figure 3, Figure 5 and Figure 6 together. Figure 6 is a structural schematic diagram of the housing in the embodiment shown in Figure 3 from the perspective of the side close to the power supply assembly.

[0070] In this embodiment, one side of the housing 510 away from the opening of the first installation position 511 is provided with a first groove 515. The first groove 515 is spaced from the first installation position 511, and the opening of the first groove 515 faces the circuit board 532 of the power supply assembly 530.

[0071] In this embodiment, the housing 510 is provided with a first air inlet channel 513 connecting the first groove 515 and the first installation position 511. The first air inlet channel 513 is located at the bottom of the first installation position 511 of the housing 510. When the atomization assembly 520 is installed in the first installation position 511, the first air inlet channel 513 is connected to the containing space 5241. The air flow in the first groove 515 can flow into the containing space 5241 through the first air inlet channel 513 and send the aerosol in the containing space 5241 into the mist channel 5221.

[0072] In one embodiment, the housing 510 is also provided with pin holes 514 connecting the first groove 515 and the first installation position 511. The pin holes 514 are located at the bottom of the first installation position 511 of the housing 510. The pin holes 514 are used to introduce the heating element pins 526 in the first installation position 511 to the side of the first groove 515 and electrically connect them with the power supply assembly.

[0073] The number of pin holes 514 corresponds to the number of heating element pins 526. In this embodiment, the number of heating element pins 526 is two, so the number of pin holes 514 is also two.

The two first mounting holes 5322 correspond to the first electrode 5311 and the second electrode 5312 respectively. When the battery 531 is fixedly connected to the circuit board 532, the first electrode 5311 and the second electrode 5312 are respectively inserted into one of the first mounting holes 5322.

[0077] The air flow bracket 533 and the electrode columns 534 are fixedly installed on the side of the circuit board 532 close to the battery 531.

[0078] The circuit board 532 is provided with second mounting holes 5323. The second mounting holes 5323 are used for fixedly installing the electrode columns 534. The electrode columns 534 are inserted into the second mounting holes 5323 and are electrically connected to the circuit board 532. Among them, the number of the second mounting holes 5323 corresponds to that of the electrode columns 534, and in this embodiment, the number is two.

[0079] After the assembly of the power supply assembly 530 in this embodiment is completed, the air flow bracket 533 is accommodated in the first groove 515 of the housing 510.

[0080] The air flow bracket 533 is provided with a second groove 5331 on the side close to the first groove 515. The second groove 5331 is connected to the first air inlet channel 513. The air flow bracket 533 is provided with a second air inlet channel 5333 in the second groove 5331. The second air inlet channel 5333 connects the second groove 5331 and the space formed between the air flow bracket 533 and the circuit board 532. The circuit board 532 is provided with a first air inlet port 5321 penetrating both sides of the circuit board 532. The first air inlet port 5321 is connected to the second air inlet channel 5333. The first air inlet port 5321 can guide the external gas to the second air inlet channel 5333, the second groove 5331, the first groove 515, and the first air inlet channel 513.

[0081] The second groove 5331 can collect the condensate on the side of the first air inlet channel 513 to prevent the condensate from flowing into the second air inlet channel 5333 and causing blockage.

[0082] In one embodiment, the air flow bracket 533 is also provided with first through holes 5332 corresponding to the electrode columns 534 in the second groove 5331. The electrode columns 534 are inserted through the first through holes 5332. When the air flow bracket 533 is fixedly installed on the circuit board 532, the electrode columns 534 pass through the first through holes 5332 and are fixedly connected to the circuit board 532. At the same time, it can also be understood that the electrode columns 534 pass through the first through holes 5332 on the side of the air flow bracket 533 close to the circuit board 532 and extend into the second groove 5331 and the first groove 515 to be electrically connected to the atomization assembly 520.

[0083] The number of the first through holes 5332 corresponds to that of the electrode columns 534. In this embodiment, the number of the first through holes 5332 is two.

[0084] Optionally, the electrode columns 534 are cylindrical poles and are vertically fixed on the circuit board 532.

[0085] The electrode columns 534 are used to electrically connect the circuit board 532 and the heating element pins 526 in the atomization assembly 520.

[0086] In this embodiment, the housing 510 is also provided with blind holes 517 in the first groove 515. The blind holes 517 are located on the side of the housing 510 away from the first installation position. The blind holes 517 are adjacent to the pin holes 514. The heating element pins 526 pass through the pin holes 514 and then are bent towards the blind holes 517 and enter the blind holes 517. After the electrode columns 534 enter the first groove 515, they are inserted into the blind holes 517 and are in interference fit with the blind holes 517, so that the electrode columns 534 and the housing 510 jointly squeeze the heating element pins 526. In this way, it can not only achieve the electrical connection between the electrode columns 534 and the heating element pins 526, but also play a role in fixing the heating element pins 526.

[0087] Therefore, the setting positions of the blind holes 517 correspond to those of the first through holes 5332 and the electrode columns 534. Meanwhile, the number of the blind holes 517 corresponds to that of the electrode columns 534. In this embodiment, the number of the blind holes 517 is two.

[0088] Optionally, the electrode columns 534 are made of metal materials such as stainless steel, aluminum, aluminum alloy, and magnesium alloy.

[0089] In one embodiment, the side of the air flow bracket 533 facing the circuit board 532 is also provided with a mounting groove 5335 and a second through hole 5334 connecting the mounting groove 5335 and the first air inlet channel 513.

[0090] The air flow sensor 535 is arranged in the mounting groove 5335 and is electrically connected to the circuit board 532. The air flow sensor 535 is used to sense and detect the gas flow situation in the second through hole 5334. When the user sucks, the air flow in the atomization space 5231 flows, and the gases in the first air inlet channel 513, the first groove 515 and the second through hole 5334 will also be taken away, forming a negative pressure. After detecting the negative pressure, the air flow sensor 535 sends a signal to the circuit board 532, and the circuit board 532 controls the operation of the atomizing device 500.

[0091] Optionally, the circuit board 532 is also provided with through holes 5324 connecting both sides of the circuit board 532 at the installation position of the air flow sensor 535. The through holes 5324 are used to guide the atmospheric air flow to the air flow sensor 535 to assist the air flow sensor 535 in detecting whether the user has a sucking action.

[0096] Optionally, the bottom cover 550 can be fixedly connected to the housing 560 by means of snap connection, adhesion, interference fit, etc.

[0097] In some embodiments, the bottom cover 550 is provided with a ventilation groove 553. The ventilation groove 553 of the bottom cover 550 faces the housing 560, and the ventilation groove 553 is located on the side of the circuit board 532 of the power supply assembly 530. The ventilation groove 553 is connected to the first air inlet port 5321.

[0098] The bottom of the bottom cover 550 is also provided with a second air inlet port 551 connecting the outside and the ventilation groove 553.

The support member 552 abuts against the power supply assembly 530 and can position and support the power supply assembly 530 to strengthen the structural stability of the atomizing device 500.

[0100] In an exemplary embodiment, the support member 552 is an annular rib arranged in the ventilation groove 553. The annular rib supports the periphery of the circuit board 532 of the power supply assembly 530.

[0101] Optionally, the bottom cover 550 is made of a light-transmitting material. Users can observe the circuit board 532 of the power supply assembly 530 through the bottom cover 550, making the product significantly different from the existing designs in appearance. Meanwhile, a light-emitting circuit (not shown in the figure) can also be provided on the side of the circuit board 532 facing the bottom cover 550. The light-emitting circuit can be configured to emit light when the atomizing device 500 is working or being sucked. Users can observe the light-emitting circuit through the bottom cover 550 and then judge the working state of the atomizing device 500.

[0102] During the assembly process of the atomizing device 500 in this embodiment, the bottom cover 550 and the housing 560 can be fixedly connected first, and then the assembled housing 510, atomization assembly 520 and power supply assembly 530 can be installed into the containing cavity 561 of the housing 560 from the side of the housing 560 away from the bottom cover 550.

[0103] Please refer to Figure 2, Figure 4, Figure 11 and Figure 12. Figure 11 is a structural schematic diagram of the suction attachment and the suction attachment bracket in an embodiment of the atomizing device in this application. Figure 12 is a structural schematic diagram of the mouthpiece in an embodiment of the atomizing device in this application.

[0104] In one embodiment, the atomizing device 500 further includes a mouthpiece assembly 540.

[0105] The mouthpiece assembly 540 is fastened to the opening on the side of the housing 560 away from the bottom cover 550 and cooperates with the bottom cover 550 to completely seal the openings on both sides of the containing cavity 561.

[0106] In some embodiments, the mouthpiece assembly 540 includes a mouthpiece 541, a suction attachment 542 and a suction attachment bracket 543.

[0107] The mouthpiece 541 is used for being fixedly connected to the housing 560. Optionally, the mouthpiece 541 can be fixedly connected to the housing 560 by means of snap connection, adhesion, interference fit, etc.

[0108] The mouthpiece 541 is provided with a third groove 5412 on the side facing the housing 560. When the mouthpiece 541 is connected to the housing 560, the third groove 5412 connects the first installation position 511 and the second installation position 512.

[0109] The suction attachment 542 is arranged in the installation position 5431 of the suction attachment bracket 543. The suction attachment 542 and the suction attachment bracket 543 are fixedly installed together in the third groove 5412 of the mouthpiece 541. Optionally, the suction attachment bracket 543 can be fixed in the third groove 5412 by snapping with the mouthpiece 541.

[0110] The suction attachment 542 is provided with a third through hole 5421. The suction attachment bracket 543 is provided with a first outlet channel 5432. The first outlet channel 5432 connects the mist channel 5221 and the third through hole 5421.

[0111] Optionally, the suction attachment bracket 543 is provided with a protrusion 5432. The first outlet channel 5432 is arranged in the protrusion 5432. The protrusion 5432 is arranged on the side of the suction attachment bracket 543 close to the aerosol pipe 522 and protrudes towards and extends into the mist channel 5221 of the aerosol pipe 522. In this way, it is convenient for the positioning of the suction attachment bracket 543 and improves the airtightness between the mist channel 5221 and the first outlet channel 5432.

[0112] Optionally, the suction attachment bracket 543 is made of silicone material with good airtightness.

[0113] The mouthpiece 541 is provided with a second outlet channel 5411 connecting the outside and the third through hole 5421. Therefore, the aerosol in the atomization space 5231 can flow out to the outside from the atomization space 5231 along the mist channel 5221, the first outlet channel 5432, the third through hole 5421 and the second outlet channel 5411 in sequence for users to inhale.

[0114] Optionally, the mouthpiece 541 can also be provided with a blocking member 5411 in the third groove 5412. The blocking member 5411 surrounds the second outlet channel 5411 and abuts against the opening of the first installation position 511. The blocking member 5411 is used to prevent the aerosol generated by atomization from overflowing and flowing into the second installation position 512 to pollute the battery 531 and prevent the taste of the aerosol from being degraded.

[0115] The suction attachment 542 is used to absorb liquid media, such as condensate, near the mist channel 5221, the first outlet channel 5432, the third through hole 5421 and the second outlet channel 5411 to prevent users from sucking the liquid media. Optionally, the suction attachment 542 can be made of porous materials or fibrous materials, such as porous ceramics, cotton, non-woven fabrics or PLA fibers, etc.

[0116] During the assembly process of the mouthpiece assembly 540 in this embodiment, the suction attachment 542 can be fixed in the suction attachment bracket 543 first, and then the suction attachment bracket 543 and the suction attachment 542 are fixed to the mouthpiece together to form the mouthpiece assembly 540. The mouthpiece assembly 540 is then fastened to the housing 560. In this way, it is convenient for the assembly of the atomizing device 500, realizes the automation of the assembly of the atomizing device 500 and reduces the assembly cost.

[0117] In summary, this application provides a modular atomizing device. Each component in the atomizing device can be assembled by the incoming material manufacturers and then fixedly assembled in sequence. During the assembly process, there is no need to weld wires, which can realize the automation of assembly and reduce the costs of wire materials and welding. Moreover, it is also convenient for the miniaturization of the atomizing device, making the atomizing device smaller and more lovely.

[0121] Please refer to Figures 13 to 15. Figure 13 is a structural schematic diagram of the atomizing device 700 in some other embodiments of this application. Figure 14 is a sectional structural schematic diagram of the atomizing device 700 in the embodiment shown in Figure 13 along the A - A direction. Figure 15 is a structural disassembly schematic diagram of the atomizing device 700 in the embodiment shown in Figure 13.

[0122] The atomizing device 700 can include a housing assembly 710, an atomization assembly 720 arranged inside the housing assembly 710, and a control assembly 730. The atomization assembly 720 is used to atomize the liquid atomization medium, and the control assembly 730 is used to control the working state of the atomization assembly 720. Among them, the housing assembly 710 can be understood as the housing 510 in the previous embodiments, the atomization assembly 720 can be understood as the atomization assembly 520 in the previous embodiments, and the control assembly 730 can be understood as the power supply assembly 530 in the previous embodiments. That is to say, although the atomizing devices in this embodiment and the embodiments shown in Figures 1 - 12 have different names, they can be interchanged in some usage scenarios based on similar or identical functions.

[0123] Among them, as the "atomizing device" described in this application, it can be applied to the atomization of liquid atomization media. Generally, it can include an atomization assembly 720 and a control assembly 730 that is mechanically and / or electrically connected to the atomization assembly 720. The atomization assembly 720 is used to heat and atomize the liquid medium, and the control assembly 730 is used to control the operation of the atomization assembly 720.

[0124] The housing assembly 710 can include a top shell 711 and a bottom shell 712 that are oppositely arranged, as well as a middle shell 713 arranged between the top shell 711 and the bottom shell 712. The middle shell 713 can be a hollow shell, specifically a frame-shaped or tubular structure with both ends open. The top shell 711 covers one open end of the middle shell 713, and the bottom shell 712 covers the other open end of the middle shell 713. That is, the top shell 711 and the bottom shell 712 respectively cover the two open ends of the middle shell 713 and enclose with the middle shell 713 to form a storage space 701 of the housing assembly 710. The atomization assembly 720 and the control assembly 730 are accommodated in the storage space 701.

[0125] Among them, an air inlet 702 can be provided on the bottom shell 712 so that external gas can enter the storage space 701 from the air inlet 702. An air outlet 703 can be provided on the top shell 711, and the gas in the storage space 701 can flow out from the air outlet 703. It can be understood that the air outlet 703 can be the suction port of the atomizing device 700 to facilitate users' suction.

[0126] When the user performs a suction operation, the external gas can enter the storage space 701 from the air inlet 702. Meanwhile, the gas atomized by the atomization assembly 720 can mix with the external gas in the storage space 701 and then flow out together from the air outlet 703.

[0127] The material of the housing assembly 710 can be glass, metal, hard plastic, etc., so that the housing assembly 710 has a certain structural strength. Among them, since the housing assembly 710 is generally directly exposed to the external environment, the housing assembly 710 can also have certain wear-resistant, corrosion-resistant and scratch-resistant properties, or a functional material for wear resistance, corrosion resistance and scratch resistance can be coated on the outer surface of the housing assembly 710. In addition, in some embodiments, a corresponding brand logo (LOGO) can also be set on the housing assembly 710 to beautify the appearance of the atomizing device 700 and improve brand recognition. It should be understood that those skilled in the art can choose the housing assembly 710 made of different materials according to different needs to adapt to the housing assembly 710 for different application scenarios, and there is no limitation on this.

[0128] Referring to Figure 16 in combination, Figure 16 is a structural disassembly schematic diagram of the atomization assembly 720 in some other embodiments of this application. The atomization assembly 720 can include an atomization shell 721, an atomization core 722 and an atomization medium carrier 723. The atomization shell 721 is arranged in the storage space 701 and is used to carry the atomization core 722 and the atomization medium. In some embodiments, it can also carry the atomization medium carrier 723. The atomization medium carrier 723 is used to carry the atomization medium for the atomization core 722 to atomize. The atomization core 722 is used to heat the atomization medium to atomize it. Among them, the atomization core 722 is electrically connected to the control assembly 730 to heat the atomization medium under the control of the control assembly 730.

[0129] Among them, the atomization medium carrier 723 can be a carrier capable of carrying the atomization medium, such as liquid storage cotton or porous ceramic body.

[0130] Optionally, the atomization core 722 can be a hollow structure, specifically a hollow tubular structure. The hollow part of it is configured to form a gas channel 724 of the atomization assembly 720. One end of the gas channel 724 is connected to the air inlet 702, and the other end is connected to the air outlet 703.

[0131] Among them, as shown in Figure 14, the atomization shell 721 can have a first cavity 7201 for accommodating the atomization core 722 and the atomization medium carrier 723. The first cavity 7201 can be a groove structure with one end open. The groove opening of the groove body faces the air outlet 703, and the bottom wall of the groove body can have an air inlet hole 7202 connected to the air inlet 702. In one embodiment, the atomization assembly 720 can also include a sealing member 725. The sealing member 725 covers the open end of the first cavity 7201 to cooperate with the atomization shell 721 to seal the first cavity 7201, and then seal the atomization core 722 placed in the first cavity 7201 to prevent the leakage of the atomization medium and also prevent the aerosol from spreading outside the gas channel 724. Optionally, the opposite sides of the sealing member 725 can respectively abut against the top shell 711 and the atomization shell 721 to achieve the sealing effect. Optionally, one of the opposite sides of the sealing member 725 can abut against the top shell 711, and the other side can abut against the atomization shell 721 and the atomization medium carrier 723. Among them, the sealing member 725 can be a sealing structure made of materials such as silica gel, rubber, foam or plastic.

[0132] In some embodiments, the sealing member 725 can be made of plastic materials such as polypropylene or polyimide. This is because, compared with plastics, silica gel has a more obvious adsorption effect on certain flavoring substances, and thus may have a more obvious impact on the decline of taste or aroma. Of course, in some application scenarios with low requirements for taste or fragrance, the sealing member 725 can be silica gel or rubber.

[0133] The sealing member 725 can have an air outlet hole 7203. The air outlet hole 7203 is respectively connected to the gas channel 724 and the air outlet 703. That is, the first cavity 7201 is respectively connected to the air outlet hole 7203 and the air inlet hole 7202. The air inlet hole 7202 is connected to the air inlet 702, and the air outlet hole 7203 is connected to the air outlet 703. External gas sequentially passes through the air inlet 702 and the air inlet hole 7202 to reach the gas channel 724 in the first cavity 7201, and the gas in the gas channel 724 sequentially flows out through the air outlet hole 7203 and the air outlet 703.

[0134] Of course, in other implementation modes, the sealing member 725 can be a cover covering the open end of the first cavity 7201, that is, the sealing member 725 can be integrally formed with the atomization shell 721 and jointly form the atomization shell 721 with the first cavity 7201, and the atomization shell 721 can be provided with an air inlet hole 7202 and an air outlet hole 7203 respectively connected to the first cavity 7201.

[0135] Optionally, the atomization medium carrier 723 is arranged in the first cavity 7201, and the atomization core 722 passes through the hollow part of the atomization medium carrier 723 so that the two ends of the gas channel 724 of the atomization core 722 can be respectively connected to the air inlet hole 7202 and the air outlet hole 7203.

[0136] Referring to Figure 17 in combination, Figure 17 is a structural disassembly schematic diagram of the control assembly 730 in some other embodiments of this application. The control assembly 730 can include a battery 731, a circuit board 732 and an air flow sensor 733. The air flow sensor 733 is arranged on the circuit board 732 and is electrically connected to the circuit board 732. The battery 731 and the air flow sensor 733 are arranged on the same side of the circuit board (relative to the upper and lower surfaces of the circuit board). The battery 731 is electrically connected to the circuit board 732 to supply power to the atomization core 722 under the control of the circuit board 732.

[0137] Among them, as shown in Figure 14, the atomization shell 721 can also have a second cavity 7204 for accommodating the battery 731 and a third cavity 7205 for accommodating the air flow sensor 733. The circuit board 732 is arranged on the side of the third cavity 7205 that is away from the first cavity 7201. Both ends of the air inlet hole 7202 are respectively connected to the first cavity 7201 and the third cavity 7205. For example, one end of the air inlet hole 7202 can penetrate through the atomization shell 721 and extend to the third cavity 7205 to achieve connection.

[0138] Furthermore, when the gas enters the gas channel 724 from the air inlet 702 and then flows out from the air outlet 703, the air flow sensor 733 can sense the gas flow and send out a response signal. The chip integrated in the air flow sensor 733 or the chip on the circuit board 732 receives the above-mentioned sensing signal and controls the electrical connection between the battery 731 and the atomization core 722 based on this sensing signal, so that the atomization core 722 can heat the atomization medium carried on the atomization medium carrier 723 to atomize it.

[0139] As mentioned before, the air inlet 702 is provided on the bottom shell 712, and the air outlet 703 is provided on the top shell 711. The external gas of the atomizing device 700 enters the atomizing device 700 from the air inlet 702, is atomized by the atomization core 722 in the gas channel 724, reaches the air outlet 703, and then flows out from the air outlet 703.

[0140] In one embodiment, the second cavity 7204 is arranged on one side of the first cavity 7201, that is, the second cavity 7204 and the first cavity 7201 can be arranged side by side. Thus, the atomization assembly 720 and the battery 731 can be arranged side by side. The third cavity 7205 is arranged on another adjacent side of the first cavity 7201, that is, the third cavity 7205 and the first cavity 7201 can be arranged on the same side of the second cavity 7204. In other words, the second cavity 7204 and the third cavity 7205 can be respectively arranged on the adjacent sides of the first cavity 7201. In this way, it can avoid that the atomizing device 700 is too long due to the sequential arrangement of the first cavity 7201, the third cavity 7205 and the second cavity 7204, which would affect the user's use experience. In addition, by arranging the second cavity 7204 side by side with the first cavity 7201 and / or arranging the second cavity 7204 and the third cavity 7205 side by side, while reducing the length of the atomizing device 700, its width can be appropriately increased to improve the user's comfort when holding it.

[0141] As shown in Figure 14, the circuit board 732 is arranged on the side of the third cavity 7205 that is away from the first cavity 7201 and covers the third cavity 7205, so that the air flow sensor 733 can be completely accommodated in the third cavity 7205. The first air hole 7321 is provided through the circuit board 732 to connect the third cavity 7205 and the air inlet 702.

[0142] When the atomizing device 700 is assembled, first, the atomization core 722 and the atomization medium carrier 723 are assembled in the first cavity 7201 of the atomization shell 721. Then, the air flow sensor 733 and the battery 731 are assembled on the circuit board 732. Further, the circuit board 732 is arranged on the side of the third cavity 7205 that is away from the first cavity 7201, so that the air flow sensor 733 enters the third cavity 7205 and the battery 731 enters the second cavity 7204, thus obtaining a preliminary assembly. The bottom shell 712 is assembled on the lower side of the middle shell 713, and the above-mentioned preliminary assembly is placed into the housing assembly 710 from the upper side of the middle shell 713.

In addition, in other implementation modes, the bottom shell 712 can be made of opaque materials, and the light-transmitting part 7121 can be a light-transmitting structure such as a light-transmitting hole formed on the bottom shell 712. The light emitted by the light source 734 can be emitted through the light-transmitting part 7121 of the bottom shell 712 to achieve a prompting effect. Among them, the light source 734 can be an LED lamp bead, etc. Optionally, the light-transmitting part 7121 can be a light-transmitting hole provided on the bottom shell 712 and reused as the air inlet 702.

[0144] Refer to Figures 18 and 19. Figure 18 is a structural schematic diagram of the atomization shell 721 in some other embodiments of this application. Figure 19 is a partial structural schematic diagram of the atomizing device 700 in some other embodiments of this application.

[0145] The atomization shell 721 can include a first shell 7211, a second shell 7212, and a surrounding wall 7213. Among them, the first shell 7211 and the second shell 7212 are bent and connected, that is, the first shell 7211 and the second shell 7212 can form a frame structure similar to an "L" shape. In some embodiments, the first shell 7211 and the surrounding wall 7213 form a generally groove shape, and the second shell 7212 divides the groove shape into two parts. Among them, the second shell 7212 serves as the bottom shell, the surrounding wall 7213 is the outer edge, and the first shell 7211 is the separator. Of course, in other implementation modes, the first shell 7211 and the second shell 7212 can be integrally formed structural parts.

[0146] The surrounding wall 7213 can be a tubular structure with both ends open, that is, the surrounding wall 7213 encloses to form a containing space with both ends open. In other words, the surrounding wall 7213 can be an annular wall. The opposite sides of the first shell 7211 abut against the inner side of the annular wall to divide the containing space of the surrounding wall into two spaces.

[0147] In some embodiments, the first shell 7211 is arranged in the containing space of the surrounding wall 7213 and cooperates with the surrounding wall 7213 to form the first cavity 7201 and the second cavity 7204. In some embodiments, the first shell 7211 cooperates with part of the surrounding wall 7213 to enclose and form the second cavity 7204. The second shell 7212 cooperates with another part of the surrounding wall 7213 to enclose and form the first cavity 7201. Among them, the first cavity 7201 and the second cavity 7204 are formed on the opposite sides of the first shell 7211. Both the first cavity 7201 and the second cavity 7204 are spaces with both ends open, and the opening directions are consistent with the opening direction of the surrounding wall 7213.

[0148] Furthermore, the second shell 7212 blocks one open end of the first cavity 7201 to isolate the first cavity 7201 and the second cavity 7204, and a third cavity 7205 is formed on the side of the second shell 7212 that is away from the first cavity 7201.

[0149] In some embodiments, the surrounding wall 7213 can include a first surrounding wall 72131 and a second surrounding wall 72132 that are oppositely arranged, that is, the first surrounding wall 72131 and the second surrounding wall 72132 form the above-mentioned annular or tubular surrounding wall 7213. Optionally, the first surrounding wall 72131 and the second surrounding wall 72132 can be two arc-shaped structures with opposite bending angles and are spliced to form the above-mentioned surrounding wall 7213.

[0150] Furthermore, the first shell 7211 is arranged between the first surrounding wall 72131 and the second surrounding wall 72132. The first shell 7211 cooperates with the first surrounding wall 72131 to enclose and form the second cavity 7204, and the first shell 7211 cooperates with the second surrounding wall 72132 to enclose and form the first cavity 7201. The second shell 7212 is arranged at one end of the second surrounding wall 72132 to block one open side of the first cavity 7201. In other words, the first shell 7211, the second shell 7212, and the second surrounding wall 72132 can cooperate to form the first cavity 7201 with one end open as described in the previous embodiments.

[0151] It should be noted that the terms "first", "second", and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", and "third" can explicitly or implicitly include at least one of such features.

[0152] Referring to Figure 14 in combination, the second shell 7212 can be provided with an air inlet hole 7202. The air inlet hole 7202 penetrates through the second shell 7212 to connect the first cavity 7201 and the third cavity 7205 respectively. The circuit board 732 is provided with a first air hole 7321 and a second air hole 7322 that are spaced apart. Among them, the position of the first air hole 7321 is correspondingly set with the air flow sensor 733. The position of the second air hole 7322 corresponds to the position of the air inlet hole 7202, and the second air hole 7322 is communicated with the air inlet hole 7202.

[0153] In one embodiment, the circuit board 732 abuts against the side of the second shell 7212 that is away from the first cavity 7201, and a third cavity 7205 is formed between the circuit board 732 and the second shell 7212. The first air hole 7321 is connected to the inside and outside of the third cavity 7205. The air inlet hole 7202 can be respectively connected to the third cavity 7205 and the second air hole 7202.

[0154] Optionally, the side of the second shell 7212 that is away from the first cavity 7205, that is, the side close to the circuit board 732, is provided with a first groove 7206 and a second groove 7207 that are spaced apart. Among them, a groove channel 7208 is provided between the first groove 7206 and the second groove 7207, so that the first groove 7206 and the second groove 7207 are communicated. Further, the air inlet hole 7202 penetrates through the bottom wall of the first groove 7206, and the circuit board 732 covers the groove opening of the first groove 7206, so that the second air hole 7322 is exposed in the first groove 7206, that is, the second air hole 7322 is connected to the first groove 7206, and then the second air hole 7322 can be connected to the air inlet hole 7202 through the first groove 7206. Among them, the groove channel 7208 can be a groove structure formed on the side of the second shell 7212 close to the circuit board 732. The two ends of the groove channel 7208 are respectively connected to the first groove 7206 and the second groove 7207.

[0155] Of course, in other implementation modes, the groove channel 7208 can also be a hole provided between the first groove 7206 and the second groove 7207, that is, the groove channel 7208 is not exposed on the surface of the second shell 7212 close to the circuit board 732, so as to prevent the condensate from directly reaching the circuit board 732 through the groove channel 7208. In other words, the groove channel 7208 penetrates through the groove wall between the first groove 7206 and the second groove 7207, and there is a gap between the groove channel 7208 and the circuit board 732.

[0156] Furthermore, the circuit board 732 covers the groove opening of the second groove 7207, so that the first air hole 7321 is correspondingly arranged with respect to the second groove 7207, that is, the first air hole 7321 is exposed in the second groove 7207. In other words, the circuit board 732 covers the groove opening of the second groove 7207 and is sealed along the periphery, and cooperates with the second shell 7212 to enclose and form the third cavity 7205. The air flow sensor 733 is assembled in the third cavity 7205, that is, the second groove 7207, and blocks the first air hole 7321. Among them, the air flow sensor 733 is spaced from the inner wall of the second groove 7207, so that a negative pressure is formed on the side of the air flow sensor 733 that is away from the circuit board 732 when the gas passes through, so as to trigger the air flow sensor 733 to work. As mentioned before, the chip integrated in the air flow sensor 733 or the chip on the circuit board 732 receives the sensing signal and controls the electrical connection between the battery 731 and the atomization core 722 based on this sensing signal. When the chip is integrated in the air flow sensor 733, the circuit board 732 can be an adapter board, and the surface can be waterproofed to avoid the influence of condensate on its work.

[0157] Of course, in other implementation modes, the circuit board 732 can be provided with a concave part corresponding to the second groove 7207, so that when the circuit board 732 covers the groove opening of the second groove 7207, part of the air flow sensor 733 is embedded in the concave part of the circuit board 732 and another part enters the second groove 7207, so that the thickness of the second shell 7212 can be reduced. Similarly, the circuit board 732 can be provided with a concave part corresponding to the first groove 7206, so that when the circuit board 732 covers the groove opening of the first groove 7206, the second air hole 7322 can be connected to the air inlet hole 7202 through the concave part of the circuit board 732 and the first groove 7206, so that the thickness of the second shell 7212 can be reduced.

[0158] In one embodiment, a mounting groove 7209 is provided on the side of the second housing 7212 that faces away from the first cavity 7205 (i.e., close to the circuit board 732), and the mounting groove 7209 is arranged around the periphery of the first groove 7206 and the second groove 7207. Part of the circuit board 732 is mounted in the mounting groove 7209, and another part extends to the second cavity 7204. The part of the circuit board 732 extending to the second cavity 7204 is disposed opposite to the battery 731. The circuit board 732 covers the notches of the first groove 7206 and the second groove 7207 to seal the first groove 7206 and the second groove 7207, thereby preventing condensate from flowing from the side of the second housing 7212 close to the circuit board 732 onto the battery 731.

[0159] Referring also to FIG. 17, the side of the battery 731 close to the circuit board 732 is provided with a first tab 7311 and a second tab 7312 arranged at intervals. The first tab 7311 and the second tab 7312 respectively abut against the part of the circuit board 732 extending to the second cavity 7204 to achieve electrical connection between the battery 731 and the circuit board 732.

[0160] Optionally, one of the first tab 7311 and the second tab 7312 can be a positive electrode, and the other can be a negative electrode. By directly abutting the first tab 7311 and the second tab 7312 against the circuit board 732, the wires used in the related art scheme where the battery 731 is connected to the circuit board 732 via wires can be eliminated, simplifying the structure of the atomizing device 700 and improving its assembly efficiency.

[0161] Optionally, the bottom shell 712 can be provided with protrusions or boss structures to support the circuit board 732 and / or the atomization shell 721, ensuring the stability of the overall structure of the atomizing device 700. Further, there is a gap between the circuit board 732 and the bottom shell 712, and the air inlet 702 on the bottom shell 712 communicates with the second air hole 7322 through the gap between the circuit board 732 and the bottom shell 712.

[0162] In one embodiment, a light source 734 can be provided on the side of the circuit board 732 facing away from the second housing 7212, and a light-transmitting portion corresponding to the light source 734 is provided on the bottom shell 712. The light emitted by the light source 734 can pass through the light-transmitting portion of the bottom shell 712 to achieve a prompting effect. Of course, in other implementations, the bottom shell 712 can be made of a transparent material, and the light emitted by the light source 734 can pass through the bottom shell 712. In addition, in some embodiments, the bottom shell 712 can be made of an opaque material, and the light-transmitting portion can be a light-transmitting structure such as a light-transmitting hole formed on the bottom shell 712. The light emitted by the light source 734 can pass through the light-transmitting portion of the bottom shell 712 to achieve a prompting effect. The light source 734 can be provided with one or more. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly specified.

[0163] As mentioned above, the atomizing core 722 is electrically connected to the circuit board 732, and under the control of the circuit board 732, the electrical connection between the atomizing core 722 and the battery 721 is realized, so that the battery 721 supplies power to the atomizing core 722 for heating, enabling the atomizing core 722 to heat and atomize the atomization medium carried on the atomization medium carrier 723.

[0164] The atomizing core 722 and the atomization medium carrier 723 are accommodated in the first cavity 7201 of the atomization shell 721, and the atomizing core 722 is electrically connected to the circuit board 732. All directional indications (such as up, down, left, right, front, rear, ...) in the embodiments of this application are only used to explain the relative positional relationship and movement between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will change accordingly.

[0165] The atomization medium carrier 723 has a hollow channel 7231, so that when one end of the atomizing core 722 is inserted into the channel 7231, the gas channel 724 of the atomizing core 722 can communicate with the channel 7231. Both ends of the channel 7231 are respectively connected to the air inlet hole 7202 and the air outlet hole 7203, so that both ends of the gas channel 724 are respectively connected to the air inlet 702 and the air outlet 703 of the housing assembly 710.

[0166] The atomizing core 722 can be inserted into the channel 7231 of the atomization medium carrier 723. The atomizing core 722 can include an atomizing tube 7221 and a heating element 7222 arranged in the atomizing tube 7221. One end of the atomizing tube 7221 is connected to the air inlet hole 7202, and the heating element 7222 is electrically connected to the circuit board 732.

[0167] Referring also to FIG. 14 and FIG. 18, an annular protrusion 7214 is provided on the side of the second housing 7212 facing away from the circuit board 732, and the annular protrusion 7212 is arranged around the periphery of the air inlet hole 7202. One end of the atomizing tube 7221 is sleeved on the annular protrusion 7212, so that the gas channel 724 of the atomizing tube 7221 is connected to the air inlet hole 7202. The heating element 7222 can include a heating body 72221 arranged on the atomizing tube 7221, and a pin 72222 with one end connected to the heating body 72221. The other end of the pin 72222 passes through the second housing 7212 and is electrically connected to the circuit board 732.

[0168] In some embodiments, the heating body 72221 is arranged on the atomizing tube 7211 to heat the atomization medium for atomization. One end of the pin 72222 is connected to the heating body 72221, and the other end is connected to the circuit board 732, so that the circuit board 732 can control the operation of the heating body 72221.

[0169] In one embodiment, a blind hole 7215 is provided on the side of the second housing 7212 close to the circuit board 732, and one end of the pin 72222 passing through the second housing 7212 extends into the blind hole 7215.

[0170] The air inlet hole 7202 penetrates through the bottom wall of the first groove 7206, and the pin 72222 passes through the bottom wall of the first groove 7206 and is spaced from the air inlet hole 7202. At the same time, the blind hole 7215 is formed on the bottom wall of the first groove 7206 and is spaced from the air inlet hole 7202. The end of the pin 72222 passing through the second housing 7212 does not protrude from the surface of the second housing 7212 close to the circuit board 732, avoiding potential electrical influences that might occur due to direct contact with the circuit board 732. In other words, the end of the pin 72222 passing through the second housing 7212 is located in the first groove 7206 and is bent, so that the pin 72222 has an end extending into the blind hole 7215.

[0171] Referring also to FIG. 17, a conductive post 7321 is provided on the circuit board 732, and the conductive post 7321 can be inserted into the blind hole 7215 to achieve electrical connection with the pin 72222.

[0172] Optionally, the pin 72222 can pass through the annular protrusion 7214 and the second housing 7212 in sequence, and be bent on the side of the second housing 7212 close to the circuit board 732 to enter the blind hole 7215. When the conductive post 7321 on the circuit board 732 enters the blind hole 7215, it can contact the pin 72222 to achieve electrical connection. In other words, the end of the pin 72222 passing through the second housing 7212 is bent on the side of the second housing 7212 close to the circuit board 732 and extends into the blind hole 7215.

[0173] In the atomizing device provided by the embodiment of this application, the first cavity, the second cavity, and the third cavity are formed on the atomization shell, and the second cavity and the third cavity are respectively arranged on adjacent sides of the first cavity. This can avoid the atomizing device being too long due to the sequential arrangement of the first cavity, the third cavity, and the second cavity, which would affect the user experience. In addition, by arranging the second cavity side by side with the first cavity, and the second cavity side by side with the third cavity, the length of the atomizing device is reduced while its width is appropriately increased, improving the user's holding comfort.

[0174] In addition, in the atomizing device provided by the embodiment of this application, the air flow sensor on the circuit board is assembled in the third cavity of the atomization shell. Compared with the related art scheme where a silicone part is provided on the atomization shell to assemble the air flow sensor, the structural cost of the silicone part can be saved, and the overall structure of the atomizing device can be more compact. In addition, compared with plastic, silicone has a more obvious adsorption effect on certain flavors and fragrances; in other words, compared with plastic materials, silicone has a more obvious negative impact on the reduction of taste or aroma.

[0175] In addition, it should be noted that the terms "include" and "have" and any variations thereof in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes unlisted steps or units, or optionally includes other steps or units inherent to these processes, methods, products, or devices.

DETAILED DESCRIPTION

[0030] The following will combine the attached drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in the field without creative work fall within the protection scope of this application.

[0031] The mention of "embodiments" in this text means that the specific features, structures or characteristics described in combination with the embodiments can be included in at least one embodiment of this application. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] This application provides an atomizing device, which is a product that can heat the atomization substrate to atomize it and generate mist. The atomizing device provided in this application is disposable, that is, the atomizing device in the embodiments of this application does not need to be charged or have its liquid storage parts replaced. It is an atomizing device that can be discarded after one use, and it is more convenient to carry, easier to use, has more stable performance and can store more atomization substrate. The disassembly scheme described in the embodiments is mainly designed for the disassembly during the manufacturer's recycling process. Generally, it is neither recommended nor required for users to disassemble it by themselves.

[0033] In the current atomizing devices on the market, it is usually necessary to use wires to electrically connect electrical components such as circuit boards, batteries and airflow sensors in the atomizing devices. However, the wires in the current atomizing devices will occupy the space in the atomizing devices, and manual welding is often required in the production process of the atomizing devices, which is time-consuming and laborious. This application aims to provide an atomizing device that is easy to assemble and has a low cost to solve the above problems.

[0034] Please refer to Figure 1, Figure 2 and Figure 3. Figure 1 is a structural schematic diagram of an embodiment of the atomizing device in this application. Figure 2 is an exploded structural schematic diagram of an embodiment of the atomizing device in this application. Figure 3 is a structural schematic diagram of the housing in an embodiment of the atomizing device in this application.

[0035] In this embodiment, the atomizing device 500 can include a housing 510, an atomization assembly 520 and a power supply assembly 530.

[0036] Among them, the housing 510 has a first installation position 511 and a second installation position 512. In this embodiment, the first installation position 511 and the second installation position 512 are in the form of cavities.

[0037] The first installation position 511 and the second installation position 512 are arranged side by side. The first installation position 511 has an opening on one side, and the second installation position 512 has openings on both sides, that is, both ends of the second installation position 512 are through; in other embodiments, the second installation position 512 can also have an opening on one side. The openings of the first installation position 511 and the second installation position 512 are used for assembling other components of the atomizing device 500.

[0038] In this embodiment, the first installation position 511 is used for installing the atomization assembly 520, and the second installation position 512 is used for installing the battery 531 in the power supply assembly 530.

[0039] The atomization assembly 520 plays a role in storing and heating the atomization substrate in this embodiment. Usually, the atomization assembly is arranged in the first installation position 511. During operation, it heats the stored atomization substrate to atomize it into an aerosol for users to inhale.

[0040] The power supply assembly 530 stores electrical energy. The power supply assembly 530 is electrically connected to the atomization assembly 520, and the atomization assembly 520 operates under the power supply of the power supply assembly 530.

[0041] The power supply assembly 530 can include a battery 531 and a circuit board 532. The battery 531 is electrically connected to the circuit board 532. Optionally, the circuit board 532 can integrate electronic components such as resistors, capacitors and inductors. The circuit board 532 can also be provided with a control circuit to control the discharge of the battery 531. The circuit board 532 can be a PCB circuit board.

[0042] In this embodiment, the battery 531 is a single-sided dual-tab battery, that is, both the positive and negative electrodes of the battery 531 are located on the same side of the battery 531. For example, the battery 531 is a capacitor battery.

[0043] In some embodiments, the battery 531 includes a first electrode 5311 and a second electrode 5312. The first electrode 5311 and the second electrode 5312 are simultaneously located on the side of the battery 531 close to the circuit board 532. The first electrode 5311 and the second electrode 5312 are fixedly connected to the circuit board 532, so that the battery 531 is fixedly connected to the circuit board 532 through the first electrode 5311 and the second electrode 5312, and the battery 531 and the circuit board 532 form an integrated structure.

[0044] In this embodiment, the first electrode 5311 and the second electrode 5312 have a certain rigidity. Therefore, in addition to conducting electricity, the first electrode 5311 and the second electrode 5312 can also support, stabilize and position the battery 531.

[0045] Optionally, the first electrode 5311 and the second electrode 5312 are made of metals such as stainless steel, aluminum, aluminum alloy, and magnesium alloy.

[0046] In one embodiment, the battery 531 is arranged in the second installation position 512. Since the second installation position 512 is arranged side by side with the first installation position 511, the battery 531 and the atomization assembly 520 in the atomizing device 500 in this embodiment are also arranged side by side.

[0047] Taking the battery 531 as a capacitor battery as an example, the battery 531 has a certain rigidity. Compared with the soft-pack batteries widely used in the prior art, the capacitor battery has a neater appearance and is easier for structural layout and mechanical installation. Therefore, when the battery 531 is accommodated in the first installation position 511, the space reserved for the size fluctuation of the battery 531 is reduced, and the space utilization rate is improved. Meanwhile, in the same battery space, the battery 531 in this embodiment has a larger battery capacity compared with the soft-pack battery, which improves the energy density of the battery 531.

[0048] Since the circuit board 532 is fixedly connected to the battery 531, when the battery 531 is accommodated in the second installation position 512, the circuit board 532 is fixedly arranged on one side of the housing 510.

[0049] Referring to Figure 2, in an exemplary embodiment, the battery 531 is cylindrical. The battery 531 is perpendicular to the circuit board 532 and fixedly connected to the circuit board 532. When the circuit board 532 is placed in the second installation position 512, the circuit board 532 is horizontally arranged on the opening of the second installation position 512.

[0050] Since the power supply assembly 530 in this embodiment is not provided with wires, and the housing 510 is respectively provided with installation spaces for the atomization assembly 520 and the power supply assembly 530, during the production and assembly process of the atomizing device 500, the circuit board 532 and the first electrode 5311 and the second electrode 5312 of the battery 531 can be fixedly connected first to form an integrated power supply assembly 530, and then the atomization assembly 520 is installed in the first installation position 511 in turn, and the battery 531 of the power supply assembly 530 is installed in the second installation position 512 to complete the production and assembly of the atomizing device 500. Therefore, there is no need to weld wires during the production process of the atomizing device 500 in this embodiment, which makes the atomizing device in this embodiment suitable for automated assembly based on mechanical equipment and can significantly reduce the overall cost of the atomizing device.

[0051] Please refer to Figure 1 - Figure 5. Figure 4 is a structural schematic diagram of the section I - I' in the embodiment shown in Figure 1. Figure 5 is an exploded structural schematic diagram of the atomization assembly in an embodiment of the atomizing device in this application.

[0052] As can be seen from the description of the above embodiments, the atomization assembly 520 plays a role in storing and heating the atomization substrate in the embodiments of the atomizing device.

[0053] In some embodiments, the atomization assembly 520 includes a liquid storage part 521, an aerosol pipe 522, an atomization pipe 523, a liquid guide part 524, a heating element 525 and heating element pins 526.

[0054] In one embodiment, the atomization assembly 520 does not include a liquid storage part 521, and the liquid medium is stored in the cavity around the atomization pipe 523.

[0055] In one embodiment, the liquid storage part 521 is used for storing the atomization substrate. Optionally, the material of the liquid storage part 521 can be non-woven fabric, integral cotton or PLA fiber. The liquid storage part 521 has an excellent adsorption effect, and the atomization substrate is stored in the liquid storage part 521.

[0056] The liquid storage part 521 is provided with an atomization channel 5211. The aerosol pipe 522, the atomization pipe 523, the liquid guide part 524, the heating element 525 and part of the heating element pins 526 are arranged in the atomization channel 5211.

[0057] Among them, the aerosol pipe 522 and the atomization pipe 523 are connected. The aerosol pipe 522 is provided with a mist channel 5221, and the atomization pipe 523 is provided with an atomization space 5231. The atomization space 5231 is connected to the mist channel 5221. In this embodiment, both the atomization space 5231 and the mist channel 5221 are located in the atomization channel 5211.

[0058] The liquid guide part 524 is arranged in the atomization space 5231. The side wall of the atomization pipe 523 is provided with an opening. The liquid guide part 524 is in contact with and connected to the liquid storage part 521 through the opening on the side wall of the atomization pipe 523 in the atomization space 5231.

[0059] When the liquid guide part 524 is in contact with the liquid storage part 521, it can introduce the atomization substrate stored in the liquid storage part 521 into the atomization space 5231.

[0060] Optionally, the material of the liquid guide part 524 can be porous materials or fibrous materials, such as porous ceramics, cotton, non-woven fabric or PLA fiber, etc.

[0061] The liquid guide part 524 is also provided with a containing space 5241. When the liquid guide part 524 is arranged in the atomization space 5231 of the atomization pipe 523, the containing space 5241 is connected to the mist channel 5221.

[0062] The heating element 525 is connected to the liquid guide part 524. In this embodiment, the heating element 525 is arranged in the containing space 5241. The heating element 525 is used for generating heat. After the liquid guide part 524 introduces the atomization substrate stored in the liquid storage part 521 into the atomization space 5231, the heating element 525 can heat and atomize the atomization substrate in the atomization space 5231 to form an aerosol, and the aerosol can flow from the atomization space 5231 into the mist channel 5221.

[0063] Optionally, the heating element 525 can be a metal heating wire or a metal heating mesh.

[0064] Optionally, the aerosol pipe 522 and the atomization pipe 523 can be stainless steel pipes or glass fiber pipes. The stainless steel pipes or glass fiber pipes can absorb the aerosol generated by atomization, and can also separate the aerosol from the liquid storage part 521 to prevent the liquid storage part 521 from adsorbing the aerosol and affecting the taste of the aerosol.

[0065] The heating element pins 526 are arranged on the side of the heating element 525 away from the mist channel 5221. One end of the heating element pins 526 is electrically connected to the heating element 525, and the other end is electrically connected to the power supply assembly 530. The power supply assembly 530 provides the electrical energy required for the atomization work of the heating element 525 through the heating element pins 526.

[0066] Optionally, the number of heating element pins 526 is two, corresponding to the positive and negative poles of the power supply assembly respectively. In other embodiments, the number of heating element pins 526 can also be three or more.

[0067] During the production and assembly of the atomization assembly 520 in this embodiment, the liquid guide part 524, the heating element 525 and the heating element pins 526 can be connected together first and then installed into the atomization channel 5211 from the atomization channel 5211 together, and then the aerosol pipe 522 is installed into the atomization channel 5211 from the other side of the atomization channel 5211 to realize the integration of the atomization assembly 520 and facilitate the installation of the atomization assembly 520. Optionally, when the aerosol pipe 522 and the atomization pipe 523 are installed in the atomization channel 5211, they can be in interference fit with the side wall of the atomization channel 5211 to strengthen the fixation of the aerosol pipe 522 and the atomization pipe 523.

[0068] After the atomization assembly 520 is assembled, the liquid storage part 521 can be installed in the first installation position 511. The aerosol pipe 522, the atomization pipe 523, the liquid guide part 524, the heating element 525 and the heating element pins 526 are installed in the first installation position 511 together with the liquid storage part 521. Therefore, the atomization assembly 520 in the atomizing device 500 in this embodiment is easy to install and facilitates the realization of the automation of the installation of the atomizing device 500.

[0069] Please refer to Figure 2, Figure 3, Figure 5 and Figure 6 together. Figure 6 is a structural schematic diagram of the housing in the embodiment shown in Figure 3 from the perspective of the side close to the power supply assembly.

[0070] In this embodiment, one side of the housing 510 away from the opening of the first installation position 511 is provided with a first groove 515. The first groove 515 is spaced from the first installation position 511, and the opening of the first groove 515 faces the circuit board 532 of the power supply assembly 530.

[0071] In this embodiment, the housing 510 is provided with a first air inlet channel 513 connecting the first groove 515 and the first installation position 511. The first air inlet channel 513 is located at the bottom of the first installation position 511 of the housing 510. When the atomization assembly 520 is installed in the first installation position 511, the first air inlet channel 513 is connected to the containing space 5241. The air flow in the first groove 515 can flow into the containing space 5241 through the first air inlet channel 513 and send the aerosol in the containing space 5241 into the mist channel 5221.

[0072] In one embodiment, the housing 510 is also provided with pin holes 514 connecting the first groove 515 and the first installation position 511. The pin holes 514 are located at the bottom of the first installation position 511 of the housing 510. The pin holes 514 are used to introduce the heating element pins 526 in the first installation position 511 to the side of the first groove 515 and electrically connect them with the power supply assembly.

[0073] The number of pin holes 514 corresponds to the number of heating element pins 526. In this embodiment, the number of heating element pins 526 is two, so the number of pin holes 514 is also two.

[0074] Please refer to Figure 5 - Figure 9. Figure 7 is a structural schematic diagram of the power supply assembly in an embodiment of the atomizing device in this application. Figure 8 is an exploded structural schematic diagram of the power supply assembly in the embodiment shown in Figure 7. Figure 9 is a structural schematic diagram of the air flow bracket in an embodiment of the atomizing device in this application from the perspective of the side facing the circuit board.

[0075] The power supply assembly 530 further includes an air flow bracket 533, electrode columns 534, and an air flow sensor 535. Among them, the number of electrode columns 534 is two.

[0076] In this embodiment, the circuit board 532 is provided with two first mounting holes 5322. The first mounting holes 5322 are used for fixedly installing the first electrode 5311 and the second electrode 5312. The two first mounting holes 5322 correspond to the first electrode 5311 and the second electrode 5312 respectively. When the battery 531 is fixedly connected to the circuit board 532, the first electrode 5311 and the second electrode 5312 are respectively inserted into one of the first mounting holes 5322.

[0077] The air flow bracket 533 and the electrode columns 534 are fixedly installed on the side of the circuit board 532 close to the battery 531.

[0078] The circuit board 532 is provided with second mounting holes 5323. The second mounting holes 5323 are used for fixedly installing the electrode columns 534. The electrode columns 534 are inserted into the second mounting holes 5323 and are electrically connected to the circuit board 532. Among them, the number of the second mounting holes 5323 corresponds to that of the electrode columns 534, and in this embodiment, the number is two.

[0079] After the assembly of the power supply assembly 530 in this embodiment is completed, the air flow bracket 533 is accommodated in the first groove 515 of the housing 510.

[0080] The air flow bracket 533 is provided with a second groove 5331 on the side close to the first groove 515. The second groove 5331 is connected to the first air inlet channel 513. The air flow bracket 533 is provided with a second air inlet channel 5333 in the second groove 5331. The second air inlet channel 5333 connects the second groove 5331 and the space formed between the air flow bracket 533 and the circuit board 532. The circuit board 532 is provided with a first air inlet port 5321 penetrating both sides of the circuit board 532. The first air inlet port 5321 is connected to the second air inlet channel 5333. The first air inlet port 5321 can guide the external gas to the second air inlet channel 5333, the second groove 5331, the first groove 515, and the first air inlet channel 513.

[0081] The second groove 5331 can collect the condensate on the side of the first air inlet channel 513 to prevent the condensate from flowing into the second air inlet channel 5333 and causing blockage.

[0082] In one embodiment, the air flow bracket 533 is also provided with first through holes 5332 corresponding to the electrode columns 534 in the second groove 5331. The electrode columns 534 are inserted through the first through holes 5332. When the air flow bracket 533 is fixedly installed on the circuit board 532, the electrode columns 534 pass through the first through holes 5332 and are fixedly connected to the circuit board 532. At the same time, it can also be understood that the electrode columns 534 pass through the first through holes 5332 on the side of the air flow bracket 533 close to the circuit board 532 and extend into the second groove 5331 and the first groove 515 to be electrically connected to the atomization assembly 520.

[0083] The number of the first through holes 5332 corresponds to that of the electrode columns 534. In this embodiment, the number of the first through holes 5332 is two.

[0084] Optionally, the electrode columns 534 are cylindrical poles and are vertically fixed on the circuit board 532.

[0085] The electrode columns 534 are used to electrically connect the circuit board 532 and the heating element pins 526 in the atomization assembly 520.

[0086] In this embodiment, the housing 510 is also provided with blind holes 517 in the first groove 515. The blind holes 517 are located on the side of the housing 510 away from the first installation position. The blind holes 517 are adjacent to the pin holes 514. The heating element pins 526 pass through the pin holes 514 and then are bent towards the blind holes 517 and enter the blind holes 517. After the electrode columns 534 enter the first groove 515, they are inserted into the blind holes 517 and are in interference fit with the blind holes 517, so that the electrode columns 534 and the housing 510 jointly squeeze the heating element pins 526. In this way, it can not only achieve the electrical connection between the electrode columns 534 and the heating element pins 526, but also play a role in fixing the heating element pins 526.

[0087] Therefore, the setting positions of the blind holes 517 correspond to those of the first through holes 5332 and the electrode columns 534. Meanwhile, the number of the blind holes 517 corresponds to that of the electrode columns 534. In this embodiment, the number of the blind holes 517 is two.

[0088] Optionally, the electrode columns 534 are made of metal materials such as stainless steel, aluminum, aluminum alloy, and magnesium alloy.

[0089] In one embodiment, the side of the air flow bracket 533 facing the circuit board 532 is also provided with a mounting groove 5335 and a second through hole 5334 connecting the mounting groove 5335 and the first air inlet channel 513.

[0090] The air flow sensor 535 is arranged in the mounting groove 5335 and is electrically connected to the circuit board 532. The air flow sensor 535 is used to sense and detect the gas flow situation in the second through hole 5334. When the user sucks, the air flow in the atomization space 5231 flows, and the gases in the first air inlet channel 513, the first groove 515 and the second through hole 5334 will also be taken away, forming a negative pressure. After detecting the negative pressure, the air flow sensor 535 sends a signal to the circuit board 532, and the circuit board 532 controls the operation of the atomizing device 500.

[0091] Optionally, the circuit board 532 is also provided with through holes 5324 connecting both sides of the circuit board 532 at the installation position of the air flow sensor 535. The through holes 5324 are used to guide the atmospheric air flow to the air flow sensor 535 to assist the air flow sensor 535 in detecting whether the user has a sucking action.

[0092] Please refer to Figure 2, Figure 4, and Figure 10. Figure 10 is a structural schematic diagram of the bottom cover in an embodiment of the atomizing device in this application.

[0093] In one embodiment, the atomizing device 500 further includes a housing 560 and a bottom cover 550.

[0094] The housing 560 is provided with a containing cavity 561 with openings on both sides. The containing cavity 561 is used to accommodate the housing 510. When the housing 510 is accommodated in the containing cavity 561, the housing 560 wraps around the side wall of the housing 510.

[0095] The bottom cover 550 is fastened to the opening on one side of the housing 560 and is fixedly connected to the housing 560. The periphery of the bottom cover 550 is connected to the periphery of the opening on one side of the housing 560. The bottom cover 550 is used to seal the opening on one side of the containing cavity 561 of the housing 560.

[0096] Optionally, the bottom cover 550 can be fixedly connected to the housing 560 by means of snap connection, adhesion, interference fit, etc.

[0097] In some embodiments, the bottom cover 550 is provided with a ventilation groove 553. The ventilation groove 553 of the bottom cover 550 faces the housing 560, and the ventilation groove 553 is located on the side of the circuit board 532 of the power supply assembly 530. The ventilation groove 553 is connected to the first air inlet port 5321.

[0098] The bottom of the bottom cover 550 is also provided with a second air inlet port 551 connecting the outside and the ventilation groove 553. Therefore, the external gas can pass through the second air inlet port 551, the ventilation groove 553, the first air inlet port 5321, the second air inlet channel 5333, the second groove 5331, the first air inlet channel 513 and the atomization space 5231 in sequence.

[0099] Optionally, the bottom cover 550 can also be provided with a support member 552 in the ventilation groove 553. The support member 552 abuts against the power supply assembly 530 and can position and support the power supply assembly 530 to strengthen the structural stability of the atomizing device 500.

[0100] In an exemplary embodiment, the support member 552 is an annular rib arranged in the ventilation groove 553. The annular rib supports the periphery of the circuit board 532 of the power supply assembly 530.

[0101] Optionally, the bottom cover 550 is made of a light-transmitting material. Users can observe the circuit board 532 of the power supply assembly 530 through the bottom cover 550, making the product significantly different from the existing designs in appearance. Meanwhile, a light-emitting circuit (not shown in the figure) can also be provided on the side of the circuit board 532 facing the bottom cover 550. The light-emitting circuit can be configured to emit light when the atomizing device 500 is working or being sucked. Users can observe the light-emitting circuit through the bottom cover 550 and then judge the working state of the atomizing device 500.

[0102] During the assembly process of the atomizing device 500 in this embodiment, the bottom cover 550 and the housing 560 can be fixedly connected first, and then the assembled housing 510, atomization assembly 520 and power supply assembly 530 can be installed into the containing cavity 561 of the housing 560 from the side of the housing 560 away from the bottom cover 550.

[0103] Please refer to Figure 2, Figure 4, Figure 11 and Figure 12. Figure 11 is a structural schematic diagram of the suction attachment and the suction attachment bracket in an embodiment of the atomizing device in this application. Figure 12 is a structural schematic diagram of the mouthpiece in an embodiment of the atomizing device in this application.

[0104] In one embodiment, the atomizing device 500 further includes a mouthpiece assembly 540.

[0105] The mouthpiece assembly 540 is fastened to the opening on the side of the housing 560 away from the bottom cover 550 and cooperates with the bottom cover 550 to completely seal the openings on both sides of the containing cavity 561.

[0106] In some embodiments, the mouthpiece assembly 540 includes a mouthpiece 541, a suction attachment 542 and a suction attachment bracket 543.

[0107] The mouthpiece 541 is used for being fixedly connected to the housing 560. Optionally, the mouthpiece 541 can be fixedly connected to the housing 560 by means of snap connection, adhesion, interference fit, etc.

[0108] The mouthpiece 541 is provided with a third groove 5412 on the side facing the housing 560. When the mouthpiece 541 is connected to the housing 560, the third groove 5412 connects the first installation position 511 and the second installation position 512.

[0109] The suction attachment 542 is arranged in the installation position 5431 of the suction attachment bracket 543. The suction attachment 542 and the suction attachment bracket 543 are fixedly installed together in the third groove 5412 of the mouthpiece 541. Optionally, the suction attachment bracket 543 can be fixed in the third groove 5412 by snapping with the mouthpiece 541.

[0110] The suction attachment 542 is provided with a third through hole 5421. The suction attachment bracket 543 is provided with a first outlet channel 5432. The first outlet channel 5432 connects the mist channel 5221 and the third through hole 5421.

[0111] Optionally, the suction attachment bracket 543 is provided with a protrusion 5432. The first outlet channel 5432 is arranged in the protrusion 5432. The protrusion 5432 is arranged on the side of the suction attachment bracket 543 close to the aerosol pipe 522 and protrudes towards and extends into the mist channel 5221 of the aerosol pipe 522. In this way, it is convenient for the positioning of the suction attachment bracket 543 and improves the airtightness between the mist channel 5221 and the first outlet channel 5432.

[0112] Optionally, the suction attachment bracket 543 is made of silicone material with good airtightness.

[0113] The mouthpiece 541 is provided with a second outlet channel 5411 connecting the outside and the third through hole 5421. Therefore, the aerosol in the atomization space 5231 can flow out to the outside from the atomization space 5231 along the mist channel 5221, the first outlet channel 5432, the third through hole 5421 and the second outlet channel 5411 in sequence for users to inhale.

[0114] Optionally, the mouthpiece 541 can also be provided with a blocking member 5411 in the third groove 5412. The blocking member 5411 surrounds the second outlet channel 5411 and abuts against the opening of the first installation position 511. The blocking member 5411 is used to prevent the aerosol generated by atomization from overflowing and flowing into the second installation position 512 to pollute the battery 531 and prevent the taste of the aerosol from being degraded.

[0115] The suction attachment 542 is used to absorb liquid media, such as condensate, near the mist channel 5221, the first outlet channel 5432, the third through hole 5421 and the second outlet channel 5411 to prevent users from sucking the liquid media. Optionally, the suction attachment 542 can be made of porous materials or fibrous materials, such as porous ceramics, cotton, non-woven fabrics or PLA fibers, etc.

[0116] During the assembly process of the mouthpiece assembly 540 in this embodiment, the suction attachment 542 can be fixed in the suction attachment bracket 543 first, and then the suction attachment bracket 543 and the suction attachment 542 are fixed to the mouthpiece together to form the mouthpiece assembly 540. The mouthpiece assembly 540 is then fastened to the housing 560. In this way, it is convenient for the assembly of the atomizing device 500, realizes the automation of the assembly of the atomizing device 500 and reduces the assembly cost.

[0117] In summary, this application provides a modular atomizing device. Each component in the atomizing device can be assembled by the incoming material manufacturers and then fixedly assembled in sequence. During the assembly process, there is no need to weld wires, which can realize the automation of assembly and reduce the costs of wire materials and welding. Moreover, it is also convenient for the miniaturization of the atomizing device, making the atomizing device smaller and more lovely.

[0121] Please refer to Figures 13 to 15. Figure 13 is a structural schematic diagram of the atomizing device 700 in some other embodiments of this application. Figure 14 is a sectional structural schematic diagram of the atomizing device 700 in the embodiment shown in Figure 13 along the A - A direction. Figure 15 is a structural disassembly schematic diagram of the atomizing device 700 in the embodiment shown in Figure 13.

[0122] The atomizing device 700 can include a housing assembly 710, an atomization assembly 720 arranged inside the housing assembly 710, and a control assembly 730. The atomization assembly 720 is used to atomize the liquid atomization medium, and the control assembly 730 is used to control the working state of the atomization assembly 720. Among them, the housing assembly 710 can be understood as the housing 510 in the previous embodiments, the atomization assembly 720 can be understood as the atomization assembly 520 in the previous embodiments, and the control assembly 730 can be understood as the power supply assembly 530 in the previous embodiments. That is to say, although the atomizing devices in this embodiment and the embodiments shown in Figures 1 - 12 have different names, they can be interchanged in some usage scenarios based on similar or identical functions.

[0123] Among them, as the "atomizing device" described in this application, it can be applied to the atomization of liquid atomization media. Generally, it can include an atomization assembly 720 and a control assembly 730 that is mechanically and / or electrically connected to the atomization assembly 720. The atomization assembly 720 is used to heat and atomize the liquid medium, and the control assembly 730 is used to control the operation of the atomization assembly 720.

[0124] The housing assembly 710 can include a top shell 711 and a bottom shell 712 that are oppositely arranged, as well as a middle shell 713 arranged between the top shell 711 and the bottom shell 712. The middle shell 713 can be a hollow shell, specifically a frame-shaped or tubular structure with both ends open. The top shell 711 covers one open end of the middle shell 713, and the bottom shell 712 covers the other open end of the middle shell 713. That is, the top shell 711 and the bottom shell 712 respectively cover the two open ends of the middle shell 713 and enclose with the middle shell 713 to form a storage space 701 of the housing assembly 710. The atomization assembly 720 and the control assembly 730 are accommodated in the storage space 701.

[0125] Among them, an air inlet 702 can be provided on the bottom shell 712 so that external gas can enter the storage space 701 from the air inlet 702. An air outlet 703 can be provided on the top shell 711, and the gas in the storage space 701 can flow out from the air outlet 703. It can be understood that the air outlet 703 can be the suction port of the atomizing device 700 to facilitate users' suction.

[0126] When the user performs a suction operation, the external gas can enter the storage space 701 from the air inlet 702. Meanwhile, the gas atomized by the atomization assembly 720 can mix with the external gas in the storage space 701 and then flow out together from the air outlet 703.

[0127] The material of the housing assembly 710 can be glass, metal, hard plastic, etc., so that the housing assembly 710 has a certain structural strength. Among them, since the housing assembly 710 is generally directly exposed to the external environment, the housing assembly 710 can also have certain wear-resistant, corrosion-resistant and scratch-resistant properties, or a functional material for wear resistance, corrosion resistance and scratch resistance can be coated on the outer surface of the housing assembly 710. In addition, in some embodiments, a corresponding brand logo (LOGO) can also be set on the housing assembly 710 to beautify the appearance of the atomizing device 700 and improve brand recognition. It should be understood that those skilled in the art can choose the housing assembly 710 made of different materials according to different needs to adapt to the housing assembly 710 for different application scenarios, and there is no limitation on this.

[0128] Referring to Figure 16 in combination, Figure 16 is a structural disassembly schematic diagram of the atomization assembly 720 in some other embodiments of this application. The atomization assembly 720 can include an atomization shell 721, an atomization core 722 and an atomization medium carrier 723. The atomization shell 721 is arranged in the storage space 701 and is used to carry the atomization core 722 and the atomization medium. In some embodiments, it can also carry the atomization medium carrier 723. The atomization medium carrier 723 is used to carry the atomization medium for the atomization core 722 to atomize. The atomization core 722 is used to heat the atomization medium to atomize it. Among them, the atomization core 722 is electrically connected to the control assembly 730 to heat the atomization medium under the control of the control assembly 730.

[0129] Among them, the atomization medium carrier 723 can be a carrier capable of carrying the atomization medium, such as liquid storage cotton or porous ceramic body.

[0130] Optionally, the atomization core 722 can be a hollow structure, specifically a hollow tubular structure. The hollow part of it is configured to form a gas channel 724 of the atomization assembly 720. One end of the gas channel 724 is connected to the air inlet 702, and the other end is connected to the air outlet 703.

[0131] Among them, as shown in Figure 14, the atomization shell 721 can have a first cavity 7201 for accommodating the atomization core 722 and the atomization medium carrier 723. The first cavity 7201 can be a groove structure with one end open. The groove opening of the groove body faces the air outlet 703, and the bottom wall of the groove body can have an air inlet hole 7202 connected to the air inlet 702. In one embodiment, the atomization assembly 720 can also include a sealing member 725. The sealing member 725 covers the open end of the first cavity 7201 to cooperate with the atomization shell 721 to seal the first cavity 7201, and then seal the atomization core 722 placed in the first cavity 7201 to prevent the leakage of the atomization medium and also prevent the aerosol from spreading outside the gas channel 724. Optionally, the opposite sides of the sealing member 725 can respectively abut against the top shell 711 and the atomization shell 721 to achieve the sealing effect. Optionally, one of the opposite sides of the sealing member 725 can abut against the top shell 711, and the other side can abut against the atomization shell 721 and the atomization medium carrier 723. Among them, the sealing member 725 can be a sealing structure made of materials such as silica gel, rubber, foam or plastic.

[0132] In some embodiments, the sealing member 725 can be made of plastic materials such as polypropylene or polyimide. This is because, compared with plastics, silica gel has a more obvious adsorption effect on certain flavoring substances, and thus may have a more obvious impact on the decline of taste or aroma. Of course, in some application scenarios with low requirements for taste or fragrance, the sealing member 725 can be silica gel or rubber.

[0133] The sealing member 725 can have an air outlet hole 7203. The air outlet hole 7203 is respectively connected to the gas channel 724 and the air outlet 703. That is, the first cavity 7201 is respectively connected to the air outlet hole 7203 and the air inlet hole 7202. The air inlet hole 7202 is connected to the air inlet 702, and the air outlet hole 7203 is connected to the air outlet 703. External gas sequentially passes through the air inlet 702 and the air inlet hole 7202 to reach the gas channel 724 in the first cavity 7201, and the gas in the gas channel 724 sequentially flows out through the air outlet hole 7203 and the air outlet 703.

[0134] Of course, in other implementation modes, the sealing member 725 can be a cover covering the open end of the first cavity 7201, that is, the sealing member 725 can be integrally formed with the atomization shell 721 and jointly form the atomization shell 721 with the first cavity 7201, and the atomization shell 721 can be provided with an air inlet hole 7202 and an air outlet hole 7203 respectively connected to the first cavity 7201.

[0135] Optionally, the atomization medium carrier 723 is arranged in the first cavity 7201, and the atomization core 722 passes through the hollow part of the atomization medium carrier 723 so that the two ends of the gas channel 724 of the atomization core 722 can be respectively connected to the air inlet hole 7202 and the air outlet hole 7203.

[0136] Referring to Figure 17 in combination, Figure 17 is a structural disassembly schematic diagram of the control assembly 730 in some other embodiments of this application. The control assembly 730 can include a battery 731, a circuit board 732 and an air flow sensor 733. The air flow sensor 733 is arranged on the circuit board 732 and is electrically connected to the circuit board 732. The battery 731 and the air flow sensor 733 are arranged on the same side of the circuit board (relative to the upper and lower surfaces of the circuit board). The battery 731 is electrically connected to the circuit board 732 to supply power to the atomization core 722 under the control of the circuit board 732.

[0137] Among them, as shown in Figure 14, the atomization shell 721 can also have a second cavity 7204 for accommodating the battery 731 and a third cavity 7205 for accommodating the air flow sensor 733. The circuit board 732 is arranged on the side of the third cavity 7205 that is away from the first cavity 7201. Both ends of the air inlet hole 7202 are respectively connected to the first cavity 7201 and the third cavity 7205. For example, one end of the air inlet hole 7202 can penetrate through the atomization shell 721 and extend to the third cavity 7205 to achieve connection.

[0138] Furthermore, when the gas enters the gas channel 724 from the air inlet 702 and then flows out from the air outlet 703, the air flow sensor 733 can sense the gas flow and send out a response signal. The chip integrated in the air flow sensor 733 or the chip on the circuit board 732 receives the above-mentioned sensing signal and controls the electrical connection between the battery 731 and the atomization core 722 based on this sensing signal, so that the atomization core 722 can heat the atomization medium carried on the atomization medium carrier 723 to atomize it.

[0139] As mentioned before, the air inlet 702 is provided on the bottom shell 712, and the air outlet 703 is provided on the top shell 711. The external gas of the atomizing device 700 enters the atomizing device 700 from the air inlet 702, is atomized by the atomization core 722 in the gas channel 724, reaches the air outlet 703, and then flows out from the air outlet 703.

[0140] In one embodiment, the second cavity 7204 is arranged on one side of the first cavity 7201, that is, the second cavity 7204 and the first cavity 7201 can be arranged side by side. Thus, the atomization assembly 720 and the battery 731 can be arranged side by side. The third cavity 7205 is arranged on another adjacent side of the first cavity 7201, that is, the third cavity 7205 and the first cavity 7201 can be arranged on the same side of the second cavity 7204. In other words, the second cavity 7204 and the third cavity 7205 can be respectively arranged on the adjacent sides of the first cavity 7201. In this way, it can avoid that the atomizing device 700 is too long due to the sequential arrangement of the first cavity 7201, the third cavity 7205 and the second cavity 7204, which would affect the user's use experience. In addition, by arranging the second cavity 7204 side by side with the first cavity 7201 and / or arranging the second cavity 7204 and the third cavity 7205 side by side, while reducing the length of the atomizing device 700, its width can be appropriately increased to improve the user's comfort when holding it.

[0141] As shown in Figure 14, the circuit board 732 is arranged on the side of the third cavity 7205 that is away from the first cavity 7201 and covers the third cavity 7205, so that the air flow sensor 733 can be completely accommodated in the third cavity 7205. The first air hole 7321 is provided through the circuit board 732 to connect the third cavity 7205 and the air inlet 702.

[0142] When the atomizing device 700 is assembled, first, the atomization core 722 and the atomization medium carrier 723 are assembled in the first cavity 7201 of the atomization shell 721. Then, the air flow sensor 733 and the battery 731 are assembled on the circuit board 732. Further, the circuit board 732 is arranged on the side of the third cavity 7205 that is away from the first cavity 7201, so that the air flow sensor 733 enters the third cavity 7205 and the battery 731 enters the second cavity 7204, thus obtaining a preliminary assembly. The bottom shell 712 is assembled on the lower side of the middle shell 713, and the above-mentioned preliminary assembly is placed into the housing assembly 710 from the upper side of the middle shell 713. Then, the top shell 711 is assembled on the upper side of the middle shell 713, that is, the assembly of the atomizing device 700 is completed.

[0143] In one embodiment, a light source 734 can be provided on the circuit board 732, and a light-transmitting part 7121 corresponding to the light source 734 is provided on the bottom shell 712. The light emitted by the light source 734 can be emitted through the light-transmitting part 7121 of the bottom shell 712 to achieve a prompting effect. Of course, in other implementation modes, the bottom shell 712 can be made of transparent or translucent materials, and the light emitted by the light source 734 can be emitted through the bottom shell 712 without the need to set the light-transmitting part 7121. In addition, in other implementation modes, the bottom shell 712 can be made of opaque materials, and the light-transmitting part 7121 can be a light-transmitting structure such as a light-transmitting hole formed on the bottom shell 712. The light emitted by the light source 734 can be emitted through the light-transmitting part 7121 of the bottom shell 712 to achieve a prompting effect. Among them, the light source 734 can be an LED lamp bead, etc. Optionally, the light-transmitting part 7121 can be a light-transmitting hole provided on the bottom shell 712 and reused as the air inlet 702.

[0144] Refer to Figures 18 and 19. Figure 18 is a structural schematic diagram of the atomization shell 721 in some other embodiments of this application. Figure 19 is a partial structural schematic diagram of the atomizing device 700 in some other embodiments of this application.

[0145] The atomization shell 721 can include a first shell 7211, a second shell 7212, and a surrounding wall 7213. Among them, the first shell 7211 and the second shell 7212 are bent and connected, that is, the first shell 7211 and the second shell 7212 can form a frame structure similar to an "L" shape. In some embodiments, the first shell 7211 and the surrounding wall 7213 form a generally groove shape, and the second shell 7212 divides the groove shape into two parts. Among them, the second shell 7212 serves as the bottom shell, the surrounding wall 7213 is the outer edge, and the first shell 7211 is the separator. Of course, in other implementation modes, the first shell 7211 and the second shell 7212 can be integrally formed structural parts.

[0146] The surrounding wall 7213 can be a tubular structure with both ends open, that is, the surrounding wall 7213 encloses to form a containing space with both ends open. In other words, the surrounding wall 7213 can be an annular wall. The opposite sides of the first shell 7211 abut against the inner side of the annular wall to divide the containing space of the surrounding wall into two spaces.

[0147] In some embodiments, the first shell 7211 is arranged in the containing space of the surrounding wall 7213 and cooperates with the surrounding wall 7213 to form the first cavity 7201 and the second cavity 7204. In some embodiments, the first shell 7211 cooperates with part of the surrounding wall 7213 to enclose and form the second cavity 7204. The second shell 7212 cooperates with another part of the surrounding wall 7213 to enclose and form the first cavity 7201. Among them, the first cavity 7201 and the second cavity 7204 are formed on the opposite sides of the first shell 7211. Both the first cavity 7201 and the second cavity 7204 are spaces with both ends open, and the opening directions are consistent with the opening direction of the surrounding wall 7213.

[0148] Furthermore, the second shell 7212 blocks one open end of the first cavity 7201 to isolate the first cavity 7201 and the second cavity 7204, and a third cavity 7205 is formed on the side of the second shell 7212 that is away from the first cavity 7201.

[0149] In some embodiments, the surrounding wall 7213 can include a first surrounding wall 72131 and a second surrounding wall 72132 that are oppositely arranged, that is, the first surrounding wall 72131 and the second surrounding wall 72132 form the above-mentioned annular or tubular surrounding wall 7213. Optionally, the first surrounding wall 72131 and the second surrounding wall 72132 can be two arc-shaped structures with opposite bending angles and are spliced to form the above-mentioned surrounding wall 7213.

[0150] Furthermore, the first shell 7211 is arranged between the first surrounding wall 72131 and the second surrounding wall 72132. The first shell 7211 cooperates with the first surrounding wall 72131 to enclose and form the second cavity 7204, and the first shell 7211 cooperates with the second surrounding wall 72132 to enclose and form the first cavity 7201. The second shell 7212 is arranged at one end of the second surrounding wall 72132 to block one open side of the first cavity 7201. In other words, the first shell 7211, the second shell 7212, and the second surrounding wall 72132 can cooperate to form the first cavity 7201 with one end open as described in the previous embodiments.

[0151] It should be noted that the terms "first", "second", and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", and "third" can explicitly or implicitly include at least one of such features.

[0152] Referring to Figure 14 in combination, the second shell 7212 can be provided with an air inlet hole 7202. The air inlet hole 7202 penetrates through the second shell 7212 to connect the first cavity 7201 and the third cavity 7205 respectively. The circuit board 732 is provided with a first air hole 7321 and a second air hole 7322 that are spaced apart. Among them, the position of the first air hole 7321 is correspondingly set with the air flow sensor 733. The position of the second air hole 7322 corresponds to the position of the air inlet hole 7202, and the second air hole 7322 is communicated with the air inlet hole 7202.

[0153] In one embodiment, the circuit board 732 abuts against the side of the second shell 7212 that is away from the first cavity 7201, and a third cavity 7205 is formed between the circuit board 732 and the second shell 7212. The first air hole 7321 is connected to the inside and outside of the third cavity 7205. The air inlet hole 7202 can be respectively connected to the third cavity 7205 and the second air hole 7202.

[0154] Optionally, the side of the second shell 7212 that is away from the first cavity 7205, that is, the side close to the circuit board 732, is provided with a first groove 7206 and a second groove 7207 that are spaced apart. Among them, a groove channel 7208 is provided between the first groove 7206 and the second groove 7207, so that the first groove 7206 and the second groove 7207 are communicated. Further, the air inlet hole 7202 penetrates through the bottom wall of the first groove 7206, and the circuit board 732 covers the groove opening of the first groove 7206, so that the second air hole 7322 is exposed in the first groove 7206, that is, the second air hole 7322 is connected to the first groove 7206, and then the second air hole 7322 can be connected to the air inlet hole 7202 through the first groove 7206. Among them, the groove channel 7208 can be a groove structure formed on the side of the second shell 7212 close to the circuit board 732. The two ends of the groove channel 7208 are respectively connected to the first groove 7206 and the second groove 7207.

[0155] Of course, in other implementation modes, the groove channel 7208 can also be a hole provided between the first groove 7206 and the second groove 7207, that is, the groove channel 7208 is not exposed on the surface of the second shell 7212 close to the circuit board 732, so as to prevent the condensate from directly reaching the circuit board 732 through the groove channel 7208. In other words, the groove channel 7208 penetrates through the groove wall between the first groove 7206 and the second groove 7207, and there is a gap between the groove channel 7208 and the circuit board 732.

[0156] Furthermore, the circuit board 732 covers the groove opening of the second groove 7207, so that the first air hole 7321 is correspondingly arranged with respect to the second groove 7207, that is, the first air hole 7321 is exposed in the second groove 7207. In other words, the circuit board 732 covers the groove opening of the second groove 7207 and is sealed along the periphery, and cooperates with the second shell 7212 to enclose and form the third cavity 7205. The air flow sensor 733 is assembled in the third cavity 7205, that is, the second groove 7207, and blocks the first air hole 7321. Among them, the air flow sensor 733 is spaced from the inner wall of the second groove 7207, so that a negative pressure is formed on the side of the air flow sensor 733 that is away from the circuit board 732 when the gas passes through, so as to trigger the air flow sensor 733 to work. As mentioned before, the chip integrated in the air flow sensor 733 or the chip on the circuit board 732 receives the sensing signal and controls the electrical connection between the battery 731 and the atomization core 722 based on this sensing signal. When the chip is integrated in the air flow sensor 733, the circuit board 732 can be an adapter board, and the surface can be waterproofed to avoid the influence of condensate on its work.

[0157] Of course, in other implementation modes, the circuit board 732 can be provided with a concave part corresponding to the second groove 7207, so that when the circuit board 732 covers the groove opening of the second groove 7207, part of the air flow sensor 733 is embedded in the concave part of the circuit board 732 and another part enters the second groove 7207, so that the thickness of the second shell 7212 can be reduced. Similarly, the circuit board 732 can be provided with a concave part corresponding to the first groove 7206, so that when the circuit board 732 covers the groove opening of the first groove 7206, the second air hole 7322 can be connected to the air inlet hole 7202 through the concave part of the circuit board 732 and the first groove 7206, so that the thickness of the second shell 7212 can be reduced.

[0158] In one embodiment, a mounting groove 7209 is provided on the side of the second housing 7212 that faces away from the first cavity 7205 (i.e., close to the circuit board 732), and the mounting groove 7209 is arranged around the periphery of the first groove 7206 and the second groove 7207. Part of the circuit board 732 is mounted in the mounting groove 7209, and another part extends to the second cavity 7204. The part of the circuit board 732 extending to the second cavity 7204 is disposed opposite to the battery 731. The circuit board 732 covers the notches of the first groove 7206 and the second groove 7207 to seal the first groove 7206 and the second groove 7207, thereby preventing condensate from flowing from the side of the second housing 7212 close to the circuit board 732 onto the battery 731.

[0159] Referring also to FIG. 17, the side of the battery 731 close to the circuit board 732 is provided with a first tab 7311 and a second tab 7312 arranged at intervals. The first tab 7311 and the second tab 7312 respectively abut against the part of the circuit board 732 extending to the second cavity 7204 to achieve electrical connection between the battery 731 and the circuit board 732.

[0160] Optionally, one of the first tab 7311 and the second tab 7312 can be a positive electrode, and the other can be a negative electrode. By directly abutting the first tab 7311 and the second tab 7312 against the circuit board 732, the wires used in the related art scheme where the battery 731 is connected to the circuit board 732 via wires can be eliminated, simplifying the structure of the atomizing device 700 and improving its assembly efficiency.

[0161] Optionally, the bottom shell 712 can be provided with protrusions or boss structures to support the circuit board 732 and / or the atomization shell 721, ensuring the stability of the overall structure of the atomizing device 700. Further, there is a gap between the circuit board 732 and the bottom shell 712, and the air inlet 702 on the bottom shell 712 communicates with the second air hole 7322 through the gap between the circuit board 732 and the bottom shell 712.

[0162] In one embodiment, a light source 734 can be provided on the side of the circuit board 732 facing away from the second housing 7212, and a light-transmitting portion corresponding to the light source 734 is provided on the bottom shell 712. The light emitted by the light source 734 can pass through the light-transmitting portion of the bottom shell 712 to achieve a prompting effect. Of course, in other implementations, the bottom shell 712 can be made of a transparent material, and the light emitted by the light source 734 can pass through the bottom shell 712. In addition, in some embodiments, the bottom shell 712 can be made of an opaque material, and the light-transmitting portion can be a light-transmitting structure such as a light-transmitting hole formed on the bottom shell 712. The light emitted by the light source 734 can pass through the light-transmitting portion of the bottom shell 712 to achieve a prompting effect. The light source 734 can be provided with one or more. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly specified.

[0163] As mentioned above, the atomizing core 722 is electrically connected to the circuit board 732, and under the control of the circuit board 732, the electrical connection between the atomizing core 722 and the battery 721 is realized, so that the battery 721 supplies power to the atomizing core 722 for heating, enabling the atomizing core 722 to heat and atomize the atomization medium carried on the atomization medium carrier 723.

[0164] The atomizing core 722 and the atomization medium carrier 723 are accommodated in the first cavity 7201 of the atomization shell 721, and the atomizing core 722 is electrically connected to the circuit board 732. All directional indications (such as up, down, left, right, front, rear, ...) in the embodiments of this application are only used to explain the relative positional relationship and movement between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will change accordingly.

[0165] The atomization medium carrier 723 has a hollow channel 7231, so that when one end of the atomizing core 722 is inserted into the channel 7231, the gas channel 724 of the atomizing core 722 can communicate with the channel 7231. Both ends of the channel 7231 are respectively connected to the air inlet hole 7202 and the air outlet hole 7203, so that both ends of the gas channel 724 are respectively connected to the air inlet 702 and the air outlet 703 of the housing assembly 710.

[0166] The atomizing core 722 can be inserted into the channel 7231 of the atomization medium carrier 723. The atomizing core 722 can include an atomizing tube 7221 and a heating element 7222 arranged in the atomizing tube 7221. One end of the atomizing tube 7221 is connected to the air inlet hole 7202, and the heating element 7222 is electrically connected to the circuit board 732.

[0167] Referring also to FIG. 14 and FIG. 18, an annular protrusion 7214 is provided on the side of the second housing 7212 facing away from the circuit board 732, and the annular protrusion 7212 is arranged around the periphery of the air inlet hole 7202. One end of the atomizing tube 7221 is sleeved on the annular protrusion 7212, so that the gas channel 724 of the atomizing tube 7221 is connected to the air inlet hole 7202. The heating element 7222 can include a heating body 72221 arranged on the atomizing tube 7221, and a pin 72222 with one end connected to the heating body 72221. The other end of the pin 72222 passes through the second housing 7212 and is electrically connected to the circuit board 732.

[0168] In some embodiments, the heating body 72221 is arranged on the atomizing tube 7211 to heat the atomization medium for atomization. One end of the pin 72222 is connected to the heating body 72221, and the other end is connected to the circuit board 732, so that the circuit board 732 can control the operation of the heating body 72221.

[0169] In one embodiment, a blind hole 7215 is provided on the side of the second housing 7212 close to the circuit board 732, and one end of the pin 72222 passing through the second housing 7212 extends into the blind hole 7215.

[0170] The air inlet hole 7202 penetrates through the bottom wall of the first groove 7206, and the pin 72222 passes through the bottom wall of the first groove 7206 and is spaced from the air inlet hole 7202. At the same time, the blind hole 7215 is formed on the bottom wall of the first groove 7206 and is spaced from the air inlet hole 7202. The end of the pin 72222 passing through the second housing 7212 does not protrude from the surface of the second housing 7212 close to the circuit board 732, avoiding potential electrical influences that might occur due to direct contact with the circuit board 732. In other words, the end of the pin 72222 passing through the second housing 7212 is located in the first groove 7206 and is bent, so that the pin 72222 has an end extending into the blind hole 7215.

[0171] Referring also to FIG. 17, a conductive post 7321 is provided on the circuit board 732, and the conductive post 7321 can be inserted into the blind hole 7215 to achieve electrical connection with the pin 72222.

[0172] Optionally, the pin 72222 can pass through the annular protrusion 7214 and the second housing 7212 in sequence, and be bent on the side of the second housing 7212 close to the circuit board 732 to enter the blind hole 7215. When the conductive post 7321 on the circuit board 732 enters the blind hole 7215, it can contact the pin 72222 to achieve electrical connection. In other words, the end of the pin 72222 passing through the second housing 7212 is bent on the side of the second housing 7212 close to the circuit board 732 and extends into the blind hole 7215.

[0173] In the atomizing device provided by the embodiment of this application, the first cavity, the second cavity, and the third cavity are formed on the atomization shell, and the second cavity and the third cavity are respectively arranged on adjacent sides of the first cavity. This can avoid the atomizing device being too long due to the sequential arrangement of the first cavity, the third cavity, and the second cavity, which would affect the user experience. In addition, by arranging the second cavity side by side with the first cavity, and the second cavity side by side with the third cavity, the length of the atomizing device is reduced while its width is appropriately increased, improving the user's holding comfort.

[0174] In addition, in the atomizing device provided by the embodiment of this application, the air flow sensor on the circuit board is assembled in the third cavity of the atomization shell. Compared with the related art scheme where a silicone part is provided on the atomization shell to assemble the air flow sensor, the structural cost of the silicone part can be saved, and the overall structure of the atomizing device can be more compact. In addition, compared with plastic, silicone has a more obvious adsorption effect on certain flavors and fragrances; in other words, compared with plastic materials, silicone has a more obvious negative impact on the reduction of taste or aroma.

[0175] In addition, it should be noted that the terms "include" and "have" and any variations thereof in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes unlisted steps or units, or optionally includes other steps or units inherent to these processes, methods, products, or devices.
