Technical Field

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

[0002] Atomizing devices are electronic devices used to heat and atomize an atomizing medium, causing it to produce an inhalable aerosol. Some atomizing devices are assembled and transported without the atomizing medium being injected into the atomizing unit. Instead, the atomizing medium is injected into the atomizing unit upon arrival at the shipping destination or before use.

[0003] In some existing atomizing devices, the atomizing matrix is ​​injected through an injection port on the atomizing unit. However, this design makes it difficult to balance injection speed and sealing design. When considering the sealing requirements of the injection port, it is usually too small, resulting in low injection efficiency; while a larger injection port leads to complex sealing design, which is not conducive to manufacturing.

This is to avoid obscuring the core parts of the present application with excessive description.

[0023] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0024] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0025] This application addresses the problem of existing atomizing devices failing to balance injection speed and sealing. By detachably mounting the nozzle onto the housing and sealing the open end of the liquid storage space with a sealant, injection can be performed quickly by removing the nozzle and opening the injection channel when needed. After injection, the nozzle can be reinstalled to reseal the injection channel. This overcomes the shortcomings of existing technologies that cannot balance injection speed and sealing, offering advantages such as fast injection speed and good sealing.

[0026] like Figures 1-5 As shown, in one embodiment, an atomizing device 1 is provided, including a housing 10, an atomizing host 20, a mouthpiece 30, and a sealing element 40, etc.

[0027] The atomizing host 20 includes a liquid storage space 21 with an open end 211 and an atomizing component 22 with an atomizing channel 221 disposed in the liquid storage space 21. The liquid storage space 21 is used to store the atomizing matrix, and when the atomizing component 22 is working, the atomizing matrix can be transferred to the atomizing component 22, where it is heated and atomized to generate an aerosol, which is then output through the atomizing channel 221.

[0028] The sealing element 40 is installed at the open end 211 of the liquid storage space 21 and is provided with an air outlet channel 41 and a liquid injection channel 42. The air outlet channel 41 is in a sealed connection with the atomization channel 221 to form an aerosol output channel. The liquid injection channel 42 is connected to the liquid storage space 21, and the atomization matrix can be injected into the liquid storage space 21 through the liquid injection channel 42.

[0029] The outer casing 10 includes a main body 11 and a connecting part 12. The atomizing host 20 is installed inside the main body 11, and the connecting part 12 at least partially presses against the side of the sealing member 40 facing away from the atomizing host 20, so that the sealing member 40 seals the open end 211 and forms an installation space 13 on the side of the sealing member 40 facing away from the atomizing host 20.

[0030] The nozzle 30 is detachably installed in the installation space 13, including a suction channel 31 that connects to the outside.

[0031] When the suction nozzle 30 is inserted into the installation space 13, the suction channel 31 is sealed to the air outlet channel 41, and the suction nozzle 30 seals the liquid inlet of the liquid injection channel 42.

[0032] When transporting or when it is not necessary to inject atomizing matrix, the mouthpiece 30 can be packaged separately from the atomizing host 20 or pre-assembled in the installation space 13 without injecting atomizing matrix into the atomizing host 20, thus meeting certain rules or special requirements.

[0033] When the atomizing matrix needs to be injected, the nozzle 30 is removed from the housing 10, opening the injection channel 42, allowing the atomizing matrix to be quickly injected into the storage space 21 through the injection channel 42. After injection, the nozzle 30 is reassembled onto the housing 10, and the injection channel 42 is resealed. By detachably installing the nozzle 30 onto the housing 10 and using the sealing element 40 to seal the open end 211 of the storage space 21, the shortcomings of existing technologies in balancing injection speed and sealing can be avoided, resulting in advantages such as fast injection speed and good sealing performance.

[0034] In one embodiment, the outer end face of the seal 40 is provided with a groove 43. The outer end face of the seal 40 is the side facing away from the atomizing host 20. The connecting portion 12 includes an insertion section 121 and a stepped surface 122. The insertion section 121 extends into the groove 43, and the outer wall of the insertion section 121 is in close contact with the inner wall of the groove 43, forming an installation space 13 inside the insertion section 121 for the nozzle 30 to be inserted and detachably installed therein.

[0035] The stepped surface 122 is located on the outside of the insertion section 121 and can be in close contact with the top surface of the periphery of the groove 43, so as to better press the seal 40 against the open end 211 of the atomizing host 20.

[0036] During assembly, the sealing element 40 is sealed to the open end 211 of the atomizing host 20, and the insertion section 121 is inserted into the groove 43, and / or the stepped surface 122 is in close contact with the peripheral top surface of the groove 43, so that the sealing element 40 seals the open end 211 of the atomizing host 20, thereby forming an installation space 13 for the nozzle 30 to be installed, ensuring the sealing of the atomizing host 20 and the ease of installation of the nozzle 30.

[0037] In some embodiments, the insertion segment 121 can be a closed ring structure to form an installation space 13 on its inner side; correspondingly, the stepped surface 122 can also be a ring structure, which is in close contact with the top surface of the groove 43. It is understood that the shapes of the insertion segment 121, the stepped surface 122, and the groove 43 can be adjusted as needed.

[0038] In one embodiment, an annular protrusion 44 is provided on the top surface of the periphery of the groove 43. The annular protrusion 44 is in close contact with the stepped surface 122, which can further improve the sealing between the connecting part 12 and the sealing member 40 and greatly reduce the possibility of leakage of the atomizing host 20.

[0039] In one embodiment, a liquid-absorbing element 50 is provided at the junction of the suction channel 31 and the air outlet channel 41, and the liquid-absorbing element 50 is located on one side of the outlet of the air outlet channel 41. By providing the liquid-absorbing element 50, the condensate formed by the aerosol condensation in the suction channel 31 can be absorbed, thereby preventing the condensate from flowing back from the air outlet channel 41 to the atomizing host 20, which would affect the operation of the atomizing host 20 and the suction taste.

[0040] In one embodiment, the suction channel 31 includes an air inlet 311 and an air outlet 312. The air inlet 311 is positioned opposite to the outlet of the atomizing channel 221, allowing the aerosol generated by atomization to be output from the atomizing channel 221 to the suction channel 31. The air outlet 312 is offset longitudinally from the outlet of the atomizing channel 221, and the liquid suction member 50 is positioned opposite to the air outlet 312. Due to the offset of the air inlet 311 and the air outlet 312, condensate can be prevented from dripping directly into the atomizing channel 221 and instead absorbed by the liquid suction member 50, resulting in a more rational structure.

[0041] In one embodiment, the sealing member 40 is provided with a flange 45 extending toward the nozzle 30. The inner wall of the suction channel 31 is in close contact with the outer wall of the flange 45, so that the suction channel 31 and the atomization channel 221 can be sealed together to form a sealed channel. The aerosol generated by the atomization component 22 can be output through the sealed channel for the user to inhale.

[0042] Furthermore, the flange 45 surrounds the periphery of the outlet of the atomizing channel 221 to form a liquid collection tank 46 for the installation of the liquid suction component 50. The condensate can be absorbed by the liquid suction component 50 and retained in the liquid collection tank 46, which can prevent the leakage of condensate and improve the user experience.

[0043] In one embodiment, the liquid storage space 21 includes a first liquid storage space 212 and a second liquid storage space 213 that are arranged side by side and isolated from each other.

[0044] The atomizing component 22 includes a first atomizing component 222 and a second atomizing component 223 respectively disposed in the first liquid storage space 212 and the second liquid storage space 213. The atomizing channel 221 includes a first atomizing channel 2211 and a second atomizing channel 2212 respectively formed in the first atomizing component 222 and the second atomizing component 223.

[0045] The air outlet channel 41 includes a first air outlet channel 411 and a second air outlet channel 412, which are respectively corresponding to the first atomization channel 2211 and the second atomization channel 2212.

[0046] The suction channel 31 includes a first suction channel 31 and a second suction channel 31 that are respectively corresponding to and isolated from the first air outlet channel 411 and the second air outlet channel 412.

[0047] The injection channel 42 includes a first set of injection channels 421 and a second set of injection channels 422, which correspond to the first liquid storage space 212 and the second liquid storage space 213, respectively.

[0048] With its dual-chamber design, and the fact that both atomization channels 221 and suction channels 31 are independent channels, different flavored atomization substrates can be injected into different liquid storage spaces 21 as needed, thereby enriching the flavors available and meeting the needs of different users.

[0049] In some embodiments, the housing 10 is provided with a middle partition 14 between the first liquid storage space 212 and the second liquid storage space 213. The middle partition 14 is provided with a detection air passage 15 extending in the longitudinal direction. By placing the detection air passage 15 in the middle partition 14, the layout is more reasonable. Furthermore, since it is located between the two liquid storage spaces 21, the inhaled airflow in the middle is more easily detected during use, thereby more effectively triggering the atomizing component 22 to work, quickly generating aerosols, and improving the user experience.

[0050] In one embodiment, the seal 40 includes a silicone body 47 and a reinforcing member 48 embedded in the silicone body 47. The addition of the reinforcing member 48 increases the strength of the seal 40, allowing for better secure sealing.

[0051] In one embodiment, the nozzle 30 further includes a sealing element 32 extending toward the atomizing host 20. When the nozzle 30 is inserted into the installation space 13, the sealing element 32 can seal the liquid injection port, thereby sealing the liquid injection channel 42 and preventing leakage of the atomizing matrix in the atomizing host 20. Understandably, the number of sealing elements 32 matches the number of liquid injection ports.

[0052] In one embodiment, a first snap-fit ​​structure 60 is provided between the main body 11 and the connecting part 12 to fasten the two together. When the connecting part 12 is fastened to the main body 11, the connecting part 12 at least partially presses against the sealing member 40 from the installation direction of the sealing member 40. In this embodiment, the main body 11 and the connecting part 12 are separate. During assembly, the atomizing host 20 is first inserted into the main body 11; then, the sealing member 40 is sealed to the open end 211 of the atomizing host 20. Then, the connecting part 12 is pressed against the sealing member 40. The first snap-fit ​​structure 60 fastens the connecting part 12 and the main body 11 together to form a whole, thereby pressing the sealing member 40 tightly against the open end 211 of the atomizing host 20.

[0053] Understandably, in some embodiments, the main body 11 and the connecting part 12 may also be an integral structure. During assembly, the sealing member 40 can be deformed by squeezing and inserted into the open end 211 of the atomizing host 20, and the connecting part 12 can be used to press against the top surface of the sealing member 40 to form an assembly.

[0054] The first snap-fit ​​structure 60 may include a slot and a hook. Understandably, the slot and hook can be respectively disposed on the main body 11 and the connecting part 12 as needed, so that they can be interlocked.

[0055] In one embodiment, a second snap-fit ​​structure 70 is provided between the nozzle 30 and the connecting portion 12 to fasten the two together. The second snap-fit ​​structure 70 allows the nozzle 30 to be detachably fastened to the connecting portion 12.

[0056] Understandably, the second snap-fit ​​structure 70 may include a slot and a hook. Understandably, the slot and hook may be respectively provided on the nozzle 30 and the connecting part 12 as needed, so that they can be interlocked.

[0057] Understandably, the atomizing host 20 may also include an atomizing component 22, a power supply, a mouthpiece 30, a control circuit board, etc., which will not be elaborated here.

[0058] During operation, the control circuit can control the power supply to power the atomizing component 22, heat the atomizing matrix in the atomizing component 22 to generate an aerosol for the user to inhale.

[0059] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
