The atomizing medium is also not limited to liquids or solids. The following examples are each schematically illustrated with respect to a liquid aerosol-generating substrate.

The aerosol-generating device generally comprises a nebulizer 100 and a power supply assembly electrically connected to the nebulizer 100 for powering the nebulizer 100. The atomizer 100 converts electrical energy into thermal energy, and the atomizing medium is converted into aerosol for the user to inhale under the action of the thermal energy.

In another aspect, referring to fig. 1-5, an atomizer 100 is provided, which includes a housing 10 and an elastomeric seal assembly 20.

The housing 10 has a liquid storage space 10a, the liquid storage space 10a being used for storing an atomizing medium.

The shell 10 is provided with at least one first opening 10b, the liquid storage space 10a can be communicated with the outside through the first opening 10b, that is, an atomization medium can be injected into the liquid storage space 10a in the shell 10, and can be guided out of the liquid storage space 10a, namely, when a finished product of the atomizer 100 is obtained for the first time, the liquid storage space 10a can be injected through the first opening 10b by utilizing the liquid guide thimble 200 so as to be convenient for a user to use; in the use process, after the atomized medium in the liquid storage space 10a is used, the atomized medium can be replenished to the liquid storage space 10a, the atomizer 100 can be used continuously, or when different atomized mediums need to be replaced, the stored atomized medium in the liquid storage space 10a can be extracted.

It should be noted that, the at least one first opening 10b refers to that the housing 10 includes one or more first openings 10b with any number, and the first openings 10b are configured to conduct the liquid storage space 10a with the outside, so as to facilitate the liquid injection into the liquid storage space 10a, and in addition, facilitate the replenishment or extraction of the atomized medium into the liquid storage space 10a during the use by a user.

Referring to fig. 1 to 5 and 14, when the atomized medium is replenished or extracted from the liquid storage space 10a, the liquid guiding thimble 200 may be used as a liquid guiding tool for guiding liquid.

The elastic sealing member 20 includes at least two sealing portions which are in sealing contact to separate the first opening 10b and the liquid storage space 10a in the initial state, that is, the sealing portions are in sealing engagement in the initial state of the elastic sealing member 20, so that the atomized medium does not flow out of the liquid storage space 10a from the first opening 10 b.

The material of the elastic sealing assembly 20 is not limited, and for example, silica gel may be used, which is nontoxic and harmless, does not generate substances harmful to the user, has strong plasticity, and is easily restored to the original state after being deformed by force, thereby maintaining the sealing performance of the elastic sealing assembly 20. Of course, the elastic sealing assembly 20 may also be made of TPE or other materials.

Referring to fig. 14, in a state that the liquid guiding thimble 200 extends between at least two sealing portions, the liquid guiding thimble 200 applies a force to the sealing portions and continuously extrudes the sealing portions, the sealing portions are elastically deformed after being stressed, and the liquid guiding thimble 200 can extend into the liquid storage space 10a through the gap between the sealing portions, so as to guide liquid.

It should be noted that the appearance of the arc-shaped liquid guiding head is not limited, and may be, for example, a hemispherical liquid guiding head or a liquid guiding head with other streamline designs.

It can be understood that after the liquid guide thimble 200 is pulled out of the liquid storage space 10a from between the sealing portions, the sealing portions are no longer subject to extrusion force, and the sealing portions recover to elastic deformation and recover to an initial sealing state, so as to seal the liquid storage space 10a. Therefore, in the whole liquid guide process, the liquid guide thimble 200 can extend into the liquid storage space 10a for liquid guide only by extending the liquid guide thimble 200 from between the sealing parts, and the liquid storage space 10a can be sealed by extracting the liquid guide thimble 200 after liquid guide is completed. The whole liquid guiding process can conduct liquid guiding without independently opening the first opening 10b, and the step of independently sealing the first opening 10b is not needed after liquid guiding is completed, so that liquid guiding procedures are reduced, and liquid guiding is more convenient.

In one embodiment, referring to FIG. 7, the deformation groove 20b is located in the elastic sealing member 20. It will be appreciated that the deformation groove 20b provided in the elastomeric seal assembly 20 may facilitate the design of the elastomeric seal assembly 20 as an outer sidewall of a cylindrical surface, such that when the elastomeric seal assembly 20 is assembled to the atomizer 100, a seal is better engaged with the mounting member.

In still other embodiments, referring to fig. 11 and 13, the deformation groove 20b is located on the outer side wall of the elastic sealing assembly 20, so that the stress portion of the sealing portion can be effectively increased, and when the liquid guiding thimble 200 enters the liquid storage space 10a, the elastic deformation portion of the elastic sealing assembly 20 is more, which is equivalent to the obtained elastic deformation force being greater, the effect of wrapping the liquid guiding thimble 200 by the sealing portion is better, and the sealing portion is easier to restore to the initial state.

In other embodiments, the elastic sealing assembly 20 may be provided with two or more deformation grooves 20b, and the number of the deformation grooves 20b on the outer sidewall and the number of the deformation grooves 20b inside the elastic sealing assembly 20 may be designed reasonably according to practical situations, so as to improve the sealing performance between the sealing portion and the liquid guiding thimble 200 and the restorability of the sealing portion while improving the sealing effect between the elastic sealing assembly 20 and the fixing member 30.

In an embodiment, referring to fig. 6 and 11, a guiding groove 20c with a second opening 20d is formed on the elastic sealing assembly 20, and at least part of the groove wall of the guiding groove 20c is disposed obliquely to the sealing portion through the plane of the second opening 20d and is connected with the sealing portion. It can be understood that, when the guide groove 20c is provided and the liquid guide thimble 200 moves from top to bottom, the liquid guide thimble 200 first contacts the groove wall of the guide groove 20c, and reaches the gap of the abutting sealing portion under the guidance of the groove wall of the guide groove 20c, so that the liquid guide thimble 200 can conveniently extend between the sealing portions and further enter the liquid storage space 10a.

The configuration of the guide groove 20c is not limited, and a part of the groove wall may be inclined from the plane of the second opening 20d to the sealing portion and connected to the sealing portion. The guide groove may be provided, for example, in an inverted tapered structure, or in a slope structure formed on one side of the groove wall, or the like.
