Referring to fig. 1 to 6 together, an atomizer according to an embodiment of the present invention will now be described. The atomizer provided by the embodiment of the utility model is suitable for an aerosol generating device, and the aerosol generating device comprises the atomizer and a power supply device 20 electrically connected with the atomizer. In use, the power supply means 20 is arranged to provide electrical power to the atomiser which is driven electrically to heat and atomise the aerosol-forming substrate stored within the atomiser for inhalation by a user to achieve a simulated smoking effect.

Referring to fig. 2, fig. 3 and fig. 8, the atomizer according to the present invention includes a cartridge case 1, an atomizing assembly 2, a liquid storage 3 and a sliding seat 4, wherein a smoking port 13 for a user to smoke is formed at a top of the cartridge case 1, and a cavity 14 is formed inside the cartridge case 1.

the sliding seat is used for abutting against the liquid storage part to enable the liquid storage part to be compressed, the sliding seat can be arranged in the cavity in a sliding mode along the axial direction of the telescopic pipe, and the second end of the telescopic pipe is supported and fixed on the sliding seat;

the bottom of the cigarette case shell is provided with an accommodating port communicated with the cavity, so that when the power supply device is accommodated in the cavity through the accommodating port, the power supply device can push the sliding seat to move axially, and the sliding seat compresses the liquid storage part.

2. A nebulizer as claimed in claim 1, the nebulizer further comprising a liquid recovery chamber disposed within the cartridge housing, the slide mount having a liquid return hole communicating with the liquid recovery chamber, such that aerosol-forming substrate in the reservoir can flow back into the liquid recovery chamber through the liquid return hole when the slide mount compresses the reservoir.

3. A nebuliser as claimed in claim 2, further comprising a liquid conducting member for conveying aerosol-forming substrate in the liquid recovery chamber to the reservoir member, the liquid conducting member extending at a first end into the liquid recovery chamber and having a second end inserted into the liquid return aperture.

4. An atomiser according to claim 1, wherein the porous reservoir medium is a porous cotton, sponge or fiberglass wick.

5. The atomizer according to claim 1, wherein said porous liquid storage medium is cylindrical, said porous liquid storage medium is axially provided with a sleeve hole in a penetrating manner, and said extension tube is inserted into said sleeve hole; the liquid inlet is positioned in the trepan boring so that the porous liquid storage medium shields the liquid inlet.

6. The atomizer according to claim 1, further comprising a flexible tube disposed in the cavity, and a sealing seat disposed in the cavity corresponding to the smoking opening, wherein the flexible tube is sleeved outside the liquid storage member, a first end of the flexible tube is connected to the sealing seat, a second end of the flexible tube is connected to the sliding seat, the sealing seat is provided with a smoke guide opening communicating with the smoking opening, a first end of the flexible tube is supported and fixed on the sealing seat, and a first end of the flexible tube is communicated with the smoke guide opening.

7. The atomizer according to any one of claims 1 to 6, further comprising a sleeve for moving a power supply device into and out of said cavity, said sleeve being axially slidably mounted over said cartridge housing along said extension tube, said atomizer further comprising a locking structure for locking said sleeve in a predetermined position on said cartridge housing.

8. The atomizer of claim 7, wherein said locking structure comprises a snap-fit member disposed on said sleeve, and first and second locating structures disposed on an outer sidewall of said cartridge housing, said first and second locating structures being spaced axially along said sleeve such that said first and second locating structures are engageable with said snap-fit member, respectively, to define said sleeve in a predetermined position on said cartridge housing.

9. A nebulizer according to any one of claims 1 to 6, wherein the telescopic tube is a bellows which is axially telescopic to adjust the axial length; or the telescopic pipe is a telescopic pipe, and the telescopic pipe comprises a first pipe and a second pipe which is connected with the first pipe in a sliding manner.

10. An aerosol generating device comprising an atomiser as claimed in any of claims 1 to 9 and power supply means for supplying power to the atomiser.
