[0036] The present application provides an atomizer to solve the problems of liquid leakage and seepage in atomizer devices in related technologies.

[0037] See also Figures 1 to 3 The embodiment of the present application provides a nebulizer, comprising: a liquid storage component 200, an atomizing component 300, a conducting component 400 and a mouthpiece 110. The liquid storage component 200 is used to store an aerosol-generating matrix, and a liquid outlet 231 is provided on the liquid storage component 200. The atomizing component 300 includes an atomizing core 310, and the atomizing core 310 is used to generate heat to atomize the liquid aerosol-generating matrix to generate an aerosol. The conducting component 400 includes a first conducting element 410 and a second conducting element 420, and the first conducting element 410 is arranged in contact with the second conducting element 420, and the second conducting element 420 can absorb the aerosol-generating matrix in the first conducting element 410. The liquid outlet 231 is configured to allow the aerosol-generating matrix in the liquid storage component 200 to flow to the first conducting element 410, and the atomizing core 310 and the second conducting element 420 are in liquid communication. The mouthpiece 110 is positioned at one end of the atomizer, and the airflow of the mouthpiece 110 is connected to the atomizing core 310 so that the generated aerosol can be inhaled.

[0038] Specifically, during use of this embodiment, the aerosol-generating substrate flows out of the liquid outlet 231 of the liquid storage assembly 200 and onto the first conducting element 410. The second conducting element 420 then absorbs the aerosol-generating substrate within the first conducting element 410. The atomizing core 310 of the atomizing assembly 300 is in fluid communication with the second conducting element 420. That is, the atomizing core 310 heats the aerosol-generating substrate within the second conducting element 420 to atomize it. The user can then inhale the aerosolized aerosol through the mouthpiece 110.

[0039] During use of this embodiment, the aerosol-generating substrate flows from the liquid outlet 231 of the liquid storage assembly 200 to the first conducting element 410, is then drawn by the second conducting element 420, and contacts the atomizer core 310. The first and second conducting elements 410, 420 guide the aerosol-generating substrate, preventing it from spilling or leaking outside the atomizer during use. This prevents leakage or seepage during use of this embodiment, thereby improving the user experience of this embodiment.

[0040] In some embodiments, for example, Figure 2 、 Figure 3 As shown, the second conducting element 420 is positioned downstream of the first conducting element 410 in the direction of aerosol inhalation. Thus, after the aerosol-generating substrate flows out of the liquid reservoir 200, it first contacts the first conducting element 410. Only after the first conducting element 410 is absorbed to near saturation or supersaturation is the aerosol-generating substrate drawn into the second conducting element 420 for heating and atomization by the atomizer core 310, preventing the second conducting element 420 from becoming supersaturated.

[0041] In the related art, the atomizing device that supplies liquid through the liquid storage component 200 is very prone to leakage or seepage during use. In order to improve the leakage situation, the size of the through hole 221 between the liquid storage component 200 and the atomizing device is usually controlled. The smaller the area of the through hole 221, the less aerosol generating matrix the liquid storage component 200 supplies to the atomizing device per unit time, and the less likely it is to leak. However, it may be difficult for the aerosol generating matrix to make up for the atomization consumption of the atomizing device, resulting in the atomizing core 310 being stuck or the atomizing device being damaged. The larger the area of the through hole 221, the more aerosol generating matrix the liquid storage component 200 supplies to the atomizing device per unit time, and the aerosol generating matrix can fully make up for the atomization consumption of the atomizing device, but it is very prone to leakage.

[0042] In this embodiment, a conductive assembly 400 is positioned between the atomizer core 310 and the liquid storage assembly 200 to direct the aerosol-generating substrate to the atomizer core 310 via the first conductive element 410 and the second conductive element 420. The first conductive element 410 directly contacts the liquid outlet 231, ensuring a sufficient supply of aerosol-generating substrate at all times. The second conductive element 420 draws aerosol-generating substrate from the first conductive element 410 to supply liquid to the atomizer core 310, preventing the core from becoming sticky. The second conductive element 420 is less likely to become oversaturated, further ensuring that this embodiment will not leak or seep during use. This embodiment ensures a sufficient liquid supply while preventing sticking, improving the user experience of the atomizer.

[0043] The first and second conducting elements 410, 420 can be made of any material, as long as they can guide the aerosol-generating substrate. For example, in this embodiment, both the first and second conducting elements 410, 420 are configured as liquid-reservoir cotton. This allows the aerosol-generating substrate to be affected by the capillary action of the liquid-reservoir cotton as it moves from the first conducting element 410 to the second conducting element 420. Only when the first conducting element 410 absorbs more liquid than the second conducting element 420 will the second conducting element 420 draw the aerosol-generating substrate from the first conducting element 410 through capillary action. When the first and second conducting elements 410 absorb similar amounts of liquid, the capillary action approaches zero, meaning the second conducting element 420 no longer absorbs liquid. This prevents oversaturation of the second conducting element 420, thereby preventing leakage or seepage during use and enhancing the user experience of this embodiment.

[0044] In some embodiments, for example, Figure 2 As shown in Figure 3, the first conducting element 410 and the second conducting element 420 are arranged in sequence in the length direction of the atomizer, and the second conducting element 420 is close to the mouthpiece 110. The second conducting element 420 is difficult to be oversaturated, that is, the aerosol generating matrix will no longer flow out of the second conducting element 420 after flowing to the second conducting element 420. The second conducting element 420 is arranged close to the mouthpiece 110. On the one hand, it shortens the distance between the atomizing core 310 and the mouthpiece 110. After the atomizing core 310 heats and atomizes the aerosol generating matrix on the second conducting element 420, it can flow to the mouthpiece 110 in time for the user to inhale, thereby improving the user experience of this embodiment. On the other hand, it also prevents the aerosol generating matrix from flowing out of the second conducting element 420 and leaking to the outside of the mouthpiece 110, thereby improving the safety and reliability of this embodiment.

[0045] In some embodiments, for example, the porosity of the first conductive element 410 is set to P1, and the porosity of the second conductive element 420 is set to P2, satisfying the following: P2 < P1. Different porosities equate to different liquid absorption capacities. The porosity of the second conductive element 420 is smaller than that of the first conductive element 410, meaning that the first conductive element 410 has a stronger liquid absorption capacity. Thus, capillary action only occurs when the amount of liquid stored in the first conductive element 410 and the second conductive element 420 exceeds a certain difference, making it more difficult for the second conductive element 420 to become oversaturated.

[0046] In some embodiments, for example, Figure 2 、 Figure 3As shown, the device further includes a housing 100, wherein the liquid storage assembly 200, the atomization assembly 300, and the conduction assembly 400 are all disposed within the housing 100. A support element 120 is disposed within the housing 100 and is fixedly disposed within the housing 100. A first conduction element 410 is disposed in contact with the support element 120, and a gap is provided between a surface of the first conduction element 410 away from the liquid outlet 231 and the support element 120.

[0047] The liquid storage component 200, the atomization component 300, and the conduction component 400 are all arranged in the housing 100. The housing 100 can protect each component from being affected by the external environment and ensure the stability of this embodiment. Secondly, the provision of the housing 100 can make the present embodiment feel better, making it easier for the user to hold or play with it, thereby increasing the playability of this embodiment. Furthermore, the first conduction element 410 is provided in contact with the support element 120, and the support element 120 provides support for the first conduction element 410, supporting the first conduction element 410 and the aerosol generating matrix it absorbs, making the overall structure of this embodiment more reasonable and reliable.

[0048] In some embodiments, for example, Figure 2 、 Figure 3 As shown, the second conducting element 420 is disposed in contact with the first conducting element 410 on a surface facing away from the support element 120, with a gap provided between the second conducting element 420 and the first conducting element 410. The contact between the first conducting element 410 and the second conducting element 420 allows the second conducting element 420 to properly absorb the aerosol-forming substrate from the first conducting element 410. The gap between the first conducting element 410 and the second conducting element 420 makes it more difficult for the second conducting element 420 to absorb the aerosol-forming substrate from the first conducting element 410. Combined with controlling the porosity of the first conducting element 410 and the second conducting element 420, this further reduces the chances of oversaturation of the second conducting element 420, thereby preventing leakage or seepage in this embodiment.

[0049] In some embodiments, for example, Figure 2 、 Figure 3As shown, the support element 120 is provided with a raised portion 121, which is inserted into the first conductive element 410. The distance between the surface of the raised portion 121 facing away from the support element 120 and the support element 120 is L1, and the thickness of the first conductive element 410 is L2, satisfying the following equation: L1 = L2. After absorbing the aerosol-generating substrate, the first conductive element 410 transmits some of its pressure to the support element 120 and some to the raised portion 121, ensuring that the first conductive element 410 can stably and reliably support the aerosol-generating substrate and remain positioned on the support element 120. The raised portion 121, inserted into the first conductive element 410, also assists in positioning the first conductive element 410 during installation, reducing the assembly difficulty of this embodiment. After assembly, it also cooperates with the housing 100 to help constrain the position of the first conductive element 410, preventing displacement and improving the reliability of this embodiment.

[0050] The height of the protrusion 121 is the same as that of the first conducting element 410 so that the contact surface of the second conducting element 420 and the first conducting element 410 remain on the same horizontal plane, so that the liquid absorption effect at any position where the second conducting element 420 contacts the first conducting element 410 is the same, ensuring that the first conducting element 410 can evenly supply liquid to the second conducting element 420.

[0051] In some embodiments, for example, Figure 2 、 Figure 3 As shown, a nozzle channel 111 is provided in the nozzle 110. The atomizer assembly 300 includes an atomizer channel 320. The atomizer core 310 is disposed in the atomizer channel 320. The atomizer channel 320 is connected to the nozzle channel 111. A communication port is provided on the atomizer channel 320 that is connected to the second conducting element 420. In this way, after the aerosol-generating substrate is sucked onto the second conducting element 420, it can flow into the atomizer channel 320 through the communication port and contact the atomizer core 310. The aerosol-generating substrate is heated and atomized by the atomizer core 310. The atomized aerosol then flows along the atomizer channel 320 into the nozzle channel 111, and then flows out of the nozzle channel 111 to the outside of the nozzle 110 for inhalation by the user.

[0052] In some embodiments, for example, Figure 2 、 Figure 3 As shown, the housing 100 is provided with an opening 130, and a cover element 500 is detachably provided at the opening 130 to seal the opening 130. During the production process, by providing the cover element 500 at the housing 100, the finished atomizer can be temporarily stored and awaiting subsequent production and processing. The housing 100 and the cover element 500 cooperate to protect the various internal components.

[0053] When this embodiment is used in an atomizer device, the cover element 500 can be removed to expose the conductive contacts in the atomizer, which are electrically connected to the battery assembly in the atomizer device, forming a complete atomizer device for normal use by the user. In addition, when the atomizer of this embodiment is used in a disposable atomizer device, the cover element 500 can also be omitted from the housing 100 to allow the atomizer to be electrically connected to the battery assembly.

[0054] In some embodiments, for example, Figure 2 、 Figure 3 As shown, the liquid storage assembly 200 includes a liquid storage space 210, which is removable from the atomizer and is used to store the aerosol-generating substrate. A liquid outlet 231 is provided in the liquid storage space 210. The aerosol-generating substrate is stored in the liquid storage space 210, which is removable from the atomizer. During normal use, the aerosol-generating substrate can flow out of the liquid outlet 231. When the aerosol-generating substrate in the liquid storage space 210 is used up, the liquid storage space 210 can be directly removed and refilled, or replaced with a new one, allowing the embodiment to be reused and extending its service life.

[0055] In some embodiments, for example, Figures 1 to 3 As shown, a limited flow space 220 is provided between the liquid storage space 210 and the first conducting element 410 to control the amount of aerosol-forming substrate flowing out of the liquid storage space 210. A through hole 221 is provided on the surface of the limited flow space 220 facing the first conducting element 410. The aerosol-forming substrate in the liquid storage space 210 flows from the liquid outlet 231 into the limited flow space 220 and then flows through the through hole 221 onto the first conducting element 410. Providing the limited flow space 220 between the liquid storage space 210 and the first conducting element 410 controls the amount of aerosol-forming substrate on the first conducting element 410. This allows for timely cessation of liquid supply to the first conducting element 410 when the first conducting element 410 is nearing saturation or oversaturation, thereby controlling the degree of liquid absorption by the first conducting element 410.

[0056] Controlling the liquid absorption degree of the first conductive element 410 indirectly controls the liquid absorption degree of the second conductive element 420 , further making it more difficult for the second conductive element 420 to be oversaturated.

[0057] In some embodiments, for example, Figures 1 to 3As shown, the flow-restricting space 220 is vertically disposed below the liquid storage space 210. A container wall 230 is disposed between the liquid storage space 210 and the flow-restricting space 220. A liquid outlet 231 is provided on the container wall 230. A flow-restricting element 240 is disposed at the liquid outlet 231. The flow-restricting element 240 is configured to allow the aerosol-generating substrate in the liquid storage space 210 to flow out of the liquid storage space 210 at a first predetermined flow rate.

[0058] The flow-limiting space 220 is vertically arranged below the liquid storage space 210, and the liquid outlet 231 is arranged on the container wall 230 between the liquid storage space 210 and the flow-limiting space 220. That is, the aerosol-generating matrix in the liquid storage space 210 will naturally flow out from the liquid outlet 231 under the action of gravity and flow into the flow-limiting space 220, and then the flow-limiting space 220 will limit the outflow amount of the aerosol-generating matrix.

[0059] The flow-restricting element 240 provided at the liquid outlet 231 prevents the aerosol-generating substrate from flowing too rapidly or uncontrollably under the influence of gravity, thereby enabling the liquid storage space 210 to supply liquid to the flow-restricting space 220 at a first predetermined flow rate. The first predetermined flow rate refers to the situation where, when the liquid storage space 210 is naturally inverted and contains 10 ml of aerosol-generating substrate, the aerosol-generating substrate will flow through the flow-restricting element 240 under the influence of gravity and be substantially drained within 15 to 60 minutes.

[0060] For example, for a liquid storage space 210 with a volume of 10 ml, the predetermined rate may be that after the liquid storage space 210 is separated and placed in a naturally inverted state, the aerosol-generating substrate in the liquid storage space 210 can basically flow out of the liquid storage space 210 within 15-45 minutes.

[0061] For example, for a liquid storage space 210 with a volume of 20 ml, the predetermined rate may be that after the liquid storage space 210 is independently separated and in a natural inverted state, the aerosol-generating matrix in the liquid storage space 210 can basically flow out of the liquid storage space 210 within 30-90 minutes.

[0062] For example, when liquid storage spaces 210 with different volumes are selected, the time for the aerosol generating substrate to flow out of the liquid storage space 210 may be different. However, under the premise that the predetermined rate remains substantially unchanged, the volume and time are positively correlated.

[0063] The design purposes of the flow-limiting space 220 are, firstly, to extend the flow path and flow time of the aerosol-generating matrix to the first conducting element 410; secondly, to prevent the aerosol-generating matrix in the liquid storage space 210 from being affected by the capillary force of the first conducting element 410, so that the predetermined rate at which the aerosol-generating matrix flows out of the liquid storage space 210 is stable.

[0064] In one embodiment, the flow-restricting space 220 has a preset volume. When matching the liquid storage space 210 with a volume of 10 ml, the preset volume is 3-5 ml, for example, 3 ml, 3.5 ml, 4 ml, 4.5 ml, or 5 ml.

[0065] In one embodiment, when the flow-restricting space 220 matches the liquid storage space 210 with a volume of 20 ml, the preset volume is 4-9 ml, such as 4 ml, 5 ml, 6 ml, 7 ml, 8 ml, and 9 ml.

[0066] The volume of the liquid storage space 210 referred to in the above two embodiments, 10 ml or 20 ml, refers to the volume of the aerosol-generating substrate contained therein, rather than the volume specification of the liquid storage space 210. 10 ml and 20 ml are two common volume specifications, but the volume specifications of the containers (i.e., the liquid storage space 210) used by different manufacturers are not uniform.

[0067] In some embodiments, for example, Figures 1 to 3 As shown, a flow limiting space 220 is provided between the flow limiting element 240 and the first conducting element 410. The flow limiting element 240 is configured to be closed by at least one of the gravity of the aerosol generating substrate in the liquid storage space 210, the gas pressure in the flow limiting space 220, and the buoyancy of the liquid in the flow limiting space 220, so that the aerosol generating substrate cannot flow out of the liquid storage space 210, or the aerosol generating substrate flows out of the liquid storage space 210 at a second preset flow rate that is lower than the first preset flow rate.

[0068] In one embodiment, the flow limiting element 240 is normally closed in the non-suction state, and the flow limiting space 220 is connected to the suction nozzle 110 (not shown). When the user suctions, the flow limiting space 220 presents a negative pressure change, so that the flow limiting element 240 opens in response to the negative pressure caused by the suction force. In order to make the flow limiting element 240 normally closed in the non-suction state and able to automatically reset, the flow limiting element 240 can be used. Figure 2 The silicone piece shown has a slit 1321 .

[0069] In one embodiment, if Figure 2As shown, in the initial state (i.e., the factory-shipped state), the flow-restricting space 220 is filled with a predetermined amount of gas, resulting in a high pressure within the flow-restricting space 220, thereby preventing the flow-restricting element 240 from deforming. At this point, the air pressure within the flow-restricting space 220 and the gravity of the liquid aerosol-generating substrate within the liquid storage space 210 reach a state of equilibrium, preventing the flow-restricting element 240 from deforming. A pressure relief hole (not shown) may be provided in the flow-restricting space 220. When the user opens the pressure relief hole, high-pressure gas escapes from the flow-restricting space 220, allowing the liquid aerosol-generating substrate to be conducted from the liquid storage space 210 to the first conducting element 410.

[0070] In one embodiment, a predetermined amount of gas is initially drawn from the liquid storage space 210, creating a negative pressure differential between the gas pressure within the liquid storage space 210 and the ambient atmospheric pressure. This negative pressure differential prevents the flow-limiting element 240 from deforming. To maintain this negative pressure differential, a sealing film (not shown) can be attached to the surface of the flow-limiting element 240. When the user removes the sealing film, the negative pressure differential disappears, allowing the liquid aerosol-generating substrate to be transferred from the liquid storage space 210 to the first conducting element 410.

[0071] Specifically, the flow restricting element 240 controls the amount and rate of aerosol-generating substrate flowing from the liquid storage space 210 into the flow restricting space 220. When the flow restricting space 220 is completely empty and the air pressure is normal, the aerosol-generating substrate flows from the liquid storage space 210 to the flow restricting space 220 under the action of gravity at a first predetermined flow rate. If, at this point, the amount of aerosol-generating substrate in the liquid storage space 210 is insufficient, or the air pressure in the flow restricting space 220 is excessive due to a blockage or other reasons, or the flow restricting space 220 is substantially full, the flow restricting element 240 can restrict the aerosol-generating substrate, causing it to stop flowing or to flow at a second predetermined flow rate that is less than the first predetermined flow rate.

[0072] Thus, during normal operation of this embodiment, the aerosol-generating substrate can flow from the liquid storage space 210 to the restricted flow space 220 at a first predetermined flow rate, and then from the restricted flow space 220 to the first conducting element 410. The second conducting element 420 absorbs the aerosol-generating substrate from the first conducting element 410 and supplies it to the atomizer core 310 for normal atomization. When the first conducting element 410 is close to saturation or oversaturation, the aerosol-generating substrate in the restricted flow space 220 no longer flows out to the first conducting element 410. In other words, the aerosol-generating substrate accumulates in the restricted flow space 220. At this time, the restricting element 240 automatically actuates to stop the aerosol-generating substrate from flowing out of the liquid storage space 210 or reduce the flow rate to prevent excessive accumulation of the aerosol-generating substrate in the restricted flow space 220 or the first conducting element 410, thereby preventing leakage or seepage in this embodiment.

[0073] In some embodiments, for example, Figure 2 、 Figure 3 As shown, the flow-restricting element 240 includes a root portion 242 attached to the edge of the liquid outlet 231 and a plurality of petals 241 extending from the root portion 242 toward the center of the liquid outlet 231. Adjacent petals 241 have gaps between them, and the petals 241 are configured to open or close the gaps in response to buoyancy. When the aerosol-generating substrate is able to flow normally at a first predetermined flow rate, the petals 241 open away from the liquid storage space 210. That is, the petals 241 elastically deform and extend into the flow-restricting space 220, opening the gaps between the petals 241. At this point, the aerosol-generating substrate can flow from the liquid storage space 210 into the flow-restricting space 220.

[0074] As the aerosol-generating substrate gradually accumulates within flow-restricted space 220, reaching a point where the liquid surface contacts flow-restricting element 240. Buoyancy forces the flow-restricting element 240 to gradually retract toward the liquid storage space 210. This is achieved by the interaction of the multiple petals 241, gradually closing the gaps between adjacent petals 241 and closing the flow-restricting element 240. This prevents the aerosol-generating substrate from flowing normally. The provision of flow-restricting element 240 further controls the amount of aerosol-generating substrate flowing out of the liquid storage space 210, thus preventing issues such as insufficient liquid supply, sticking, or leakage in this embodiment.

[0075] In some embodiments, the flow limiting element 240 is illustratively made of an elastic material. In this embodiment, as long as the flow limiting element 240 can deform normally so that the gap between the petals 241 can open or close normally, the specific material of the elastic material is not limited. The flow limiting element 240 can be configured as silicone, rubber, or inorganic fiber materials according to actual needs.
