Referring to fig. 1 and 6, the nozzle 200 has a liquid inlet, an air inlet and a mist outlet, the air pump 2 is communicated with the air inlet, and the liquid inlet is communicated with the liquid storage bin 300. The reservoir 300 is used to deliver liquid aerosol-generating substrate to the liquid inlet. The outlet of the air pump 2 is communicated with the air inlet, and the air pump 2 is used for conveying air flow to the air inlet. The air flow from the air pump 2 interacts with the liquid aerosol-generating substrate such that the aerosol-generating substrate is atomized and aerosol is expelled from the aerosol-generating outlet.

An aerosol is a colloidal dispersion formed by dispersing a liquid and suspending in a gaseous medium. The aerosol can be inhaled by the nose and/or mouth of the user.

The air flow from the air pump 2 interacts with the liquid aerosol-generating substrate to generate an aerosol, which may be for example an air flow impinging on the liquid aerosol-generating substrate, such that the liquid aerosol-generating substrate is atomized into an aerosol. I.e. the liquid aerosol-generating substrate is impacted and cut by the airflow such that the liquid aerosol-generating substrate is atomized and dispersed into atomized droplets. The air pump 2 may compress the gas to generate an air flow such that the air flow impinges on the liquid aerosol-generating substrate.

Referring to fig. 1 to 4, an air pump assembly for an atomizing device is further provided according to an embodiment of the present utility model, and the air pump assembly includes a housing 1, an air pump 2 and a support member 3. The housing 1 is formed with a housing chamber 1a, the air pump 2 is located in the housing chamber 1a, and the support 3 is supported between the circumferential surface of the air pump 2 and the chamber wall surface of the housing chamber 1 a. Specifically, the outlet of the air pump 2 emits an air flow that interacts with the liquid aerosol-generating substrate to disperse the liquid aerosol-generating substrate into an aerosol. In this way, the support 3 can limit the dynamic displacement of the air pump 2 in the radial direction.

According to the air pump assembly provided by the embodiment of the utility model, the accommodating cavity 1a provides the mounting position for the air pump 2, and as the air pump 2 can generate displacement along the radial direction of the air pump 2 during operation, if a gap exists between the circumferential surface of the air pump 2 and the cavity wall surface of the accommodating cavity 1a, the air pump 2 can collide with the cavity wall surface of the accommodating cavity 1a, so that vibration is transmitted to the shell 1 to generate noise, and therefore, the air pump assembly is supported between the circumferential surface of the air pump 2 and the cavity wall surface of the accommodating cavity 1a through the supporting piece 3, and the supporting piece 3 can limit the air pump 2 to move towards the cavity wall surface of the accommodating cavity 1a, so that the air pump 2 cannot collide with the cavity wall surface of the accommodating cavity 1a, the constraint on the air pump 2 is enhanced, and the noise is reduced.

That is, the support 3 is not deformed by the impact force of the air pump 2 striking the support 3. In this way, the support 3 can limit the movement of the air pump 2 towards the cavity wall surface of the accommodating cavity 1a, so that the air pump 2 cannot strike the cavity wall surface of the accommodating cavity 1a, the constraint on the air pump 2 is enhanced, and the noise is reduced.

In one embodiment, referring to fig. 4 and 5, the support 3 is a ring-shaped structure surrounding the circumferential surface of the air pump 2. By the design, on one hand, each part of the air pump 2 along the circumferential direction can be supported by the supporting piece 3, so that the reliability is good. On the other hand, the support 3 has few installation steps, simple and convenient operation and high assembly efficiency.

On the other hand, each portion of the air pump 2 in the axial direction may be subjected to vibration displacement in the radial direction, and a plurality of support members 3 are used to provide good support for each portion of the air pump 2 in the axial direction.

It should be noted that the number of the substrates, the number is multiple including two one and more than two.

In one embodiment, referring to fig. 2 to 4, the number of the supporting members 3 is 2 to 5. The number of supports 3 is, for example, 2, 3, 4 or 5, etc. In this way, the dimension of the single support 3 in the axial direction can be relatively small, and the contact area between the support 3 and the cavity wall surface of the accommodating cavity 1a is relatively small, so that the rigid contact area is reduced, and the solid sound propagation is reduced, thus, the production cost is low, and the air pump 2 can be stably supported and the solid sound propagation is reduced.

The cross-sectional shape of the support 3 may be circular, oval, polygonal, etc. The cross-sectional shape of the support 3 is a shape in which the support 3 takes a plane perpendicular to the extending direction of the support 3 as a cross-section, which is parallel to the axial direction of the air pump 2.

In one embodiment, referring to fig. 4 and 5, the cross-sectional shape of the support member 3 is circular. The cross-sectional shape of the support member 3 is circular, so that the support member 3 is in substantially line contact with the cavity wall surface of the accommodating cavity 1a, and the contact area between the support member 3 and the cavity wall surface of the accommodating cavity 1a is small, thereby reducing the propagation of the structure-borne sound.

In one embodiment, the diameter of the cross section of the support 3 is 1mm (millimeters) to 1.5mm. Illustratively, the support 3 has a diameter of 1mm, 1.05mm, 1.1mm, 1.15mm, 1.2mm, 1.3mm, 1.4mm or 1.5mm, etc. So designed, the distance between the circumferential surface of the air pump 2 and the circumferential surface of the accommodating chamber 1a is moderate, which is convenient for both assembling the support 3 to the air pump 2 and assembling the air pump 2 and the support 3 into the accommodating chamber 1 a.

In one embodiment, the support 3 is a rigid structure. The rigid structure is not deformed by the impact force of the air pump 2 striking the support 3, the support 3.
