Abstract

An atomizing nozzle of an electronic atomizing inhalator is provided. The inhalator includes a casing body, a closure wall at the opening of the front end of the casing body, a gas-outlet aperture on the closure wall, and a rear closure provided at the opening of the rear end of the casing body. A gas-inlet aperture is in the rear closure. A liquid-container and heater are provided in the cavity formed by the casing body, the closure wall and the rear closure. An airflow-passage connecting to the gas-outlet aperture is provided between the casing body and the liquid-container. A liquid-guiding device closes the liquid-container at the opening of the liquid-container. No liquid-storage medium is provided in the liquid-container. A connection-passage for connecting the airflow-passage and the gas-inlet aperture is provided between the liquid-guiding device and the rear closure. The heater is provided on the top of the rear closure, contacting the lower surface of the liquid-guiding device, with at least part of the heater located in the connection-passage.

First claim

The invention claimed is:

1. An atomizing nozzle of an electronic atomizing inhalator, comprising a tubular casing body, provided with a closure wall at an opening of a front end of said casing body, with a gas-outlet aperture on said closure wall; and a rear closure provided at an opening of a rear end of said casing body, with a gas-inlet aperture on said rear closure; a liquid-container and heater being provided in a cavity formed by said casing body, said closure wall and said rear closure; an airflow-passage connecting to the gas-outlet aperture is provided along a radial axis between said casing body and said liquid-container; characterized in that the nozzle further comprises a liquid-guiding device, which closes said liquid-container at an opening of said liquid-container, no liquid-storage medium being arranged in the liquid-container; a connection-passage for connecting the airflow-passage and said gas-inlet aperture is provided between said liquid-guiding device and said rear closure, said heater is provided on a top of said rear closure, contacting a lower surface of said liquid-guiding device, with at least part of said heater located in said connection-passage.

2. An atomizing nozzle of an electronic atomizing inhalator according to claim 1 , characterized in that a mouth part of said liquid-container is of a wide-opening type,
with a position step provided at an inside of said mouth part, a spacer is provided between said position step and said liquid-guiding device, with liquid-draining apertures provided on said spacer.

3. An atomizing nozzle of an electronic atomizing inhalator according to claim 1 , characterized in that a spreading-spacer is provided on the lower surface of said liquid-guiding device, said heater contacting the lower surface of said spreading-spacer.

4. An atomizing nozzle of an electronic atomizing inhalator according to claim 1 , characterized in that, said heater is wound around a heat-resisting fibre core.

5. An atomizing nozzle of an electronic atomizing inhalator according to claim 1 , characterized in that a gas pipe is arranged in said liquid-container, with one end of said gas pipe extending into said liquid-guiding device, and another end of said gas pipe extending to an upper part of said liquid-container.

6. An atomizing nozzle of an electronic atomizing inhalator according to any one of claims 1 - 5 , characterized in that at least part of said liquid-guiding device is inserted into a mouth part of said liquid-container.

7. An atomizing nozzle of an electronic atomizing inhalator according to any one of claims 1 - 5 , characterized in that convex columns are arranged on a top end of said rear closure, with the heater erected across said convex columns, a space around said convex columns then forming said connection-passage.

8. An atomizing nozzle of an electronic atomizing inhalator according to claim 7 , characterized in that a semicircular-shaped groove is provided on the top of said convex columns, said heater being erected in said groove.

9. An atomizing nozzle of an electronic atomizing inhalator according to claim 7 , characterized in that, a sealing ring is provided between said casing body and the back end of said rear closure.

10. An atomizing nozzle of an electronic atomizing inhalator according to claim 9 , characterized in that, said rear closure comprises a fixing seat for said heater and a sealing seat, said fixing seat being provided on said sealing seat, said sealing ring being provided between said sealing seat and said casing body for sealing, said gas-inlet aperture and said convex columns being provided on the top end of said fixing seat for said heater.

11. The atomizing nozzle of claim 1 , further comprising the airflow-passage being partially defined by an outer surface of the liquid container.

12. The atomizing nozzle of claim 1 , further comprising:
an outer casing having a circular cross section;
the liquid container having a truncated circular cross section with a flat portion;
the outer wall of the liquid container at the flat portion and an adjacent portion of an inner surface of the outer casing defining the airflow-passage.
