Abstract

An ultrasonic electronic cigarette atomizing core and atomizer is provided, the atomizing core including an atomizing core sleeve, and tobacco tar guide cotton and an atomizing piece in the atomizing core sleeve.

First claim

The invention claimed is:

1. An ultrasonic electronic cigarette atomizing core, comprising an atomizing core sleeve, tobacco tar guide cotton, and an atomizing piece in the atomizing core sleeve, wherein:
a bottom surface of the tobacco tar guide cotton is in contact with a top surface of the atomizing piece,
a first through hole is formed in a position on the tobacco tar guide cotton, which corresponds to the center of the atomizing piece,
the atomizing core sleeve comprises an atomizing core inner sleeve and an atomizing core outer sleeve sheathed at an outside of the atomizing core inner sleeve,
the tobacco tar guide cotton is of a cup-shaped structure with an upward opening, and
a side wall of the tobacco tar guide cotton is sandwiched between the atomizing core inner sleeve and the atomizing core outer sleeve.

2. The ultrasonic electronic cigarette atomizing core of claim 1 , wherein at least one second through hole is further formed in the bottom surface of the tobacco tar guide cotton.

3. The ultrasonic electronic cigarette atomizing core of claim 1 , wherein vent grooves are uniformly formed in a boundary area of the side wall and the bottom surface of the tobacco tar guide cotton in the circumferential direction, and the area provided with no vent groove at the bottom surface of the tobacco tar guide cotton is in contact with the atomizing piece.

4. The ultrasonic electronic cigarette atomizing core of claim 1 , wherein the bottom surface of the tobacco tar guide cotton is a downward protruding circular arc surface, and the circular arc surface is in contact with a central area of the atomizing piece.

5. The ultrasonic electronic cigarette atomizing core of claim 1 , wherein a tobacco tar inlet hole leading to the tobacco tar guide cotton is formed in the atomizing core outer sleeve.

6. The ultrasonic electronic cigarette atomizing core of claim 1 , wherein at least one groove is formed in a position, which corresponds to the tobacco tar guide cotton, on an outer side wall of the atomizing core inner sleeve.

7. The ultrasonic electronic cigarette atomizing core of claim 1 , wherein:
the ultrasonic electronic cigarette atomizing core further comprises an elastic bracket,
a step is formed on an inner side wall of the atomizing core inner sleeve,
a top end of the elastic bracket is clamped at the step, and
an other end of the elastic bracket extrudes an inner bottom surface of the tobacco tar guide cotton.

8. An ultrasonic electronic cigarette atomizer, comprising an atomizer outer pipe, wherein an ultrasonic electronic cigarette atomizing core is arranged in the atomizer outer pipe, the ultrasonic electronic cigarette atomizing core comprising an atomizing core sleeve, tobacco tar guide cotton, and an atomizing piece in the atomizing core sleeve, wherein:
a bottom surface of the tobacco tar guide cotton is in contact with a top surface of the atomizing piece,
a first through hole is formed in a position on the tobacco tar guide cotton, which corresponds to the center of the atomizing piece,
the atomizing core sleeve comprises an atomizing core inner sleeve and an atomizing core outer sleeve sheathed at an outside of the atomizing core inner sleeve,
the tobacco tar guide cotton is of a cup-shaped structure with an upward opening, and
a side wall of the tobacco tar guide cotton is sandwiched between the atomizing core inner sleeve and the atomizing core outer sleeve.

9. The ultrasonic electronic cigarette atomizer of claim 8 , wherein the ultrasonic electronic cigarette atomizer further comprises a vent pipe, a first connecting seat, an airflow baffle, and a suction nozzle, wherein:
an air inlet hole is formed in a side wall of a bottom of the suction nozzle,
a bottom end of the suction nozzle is connected with a top end of a side wall of the atomizer outer pipe,
a bottom end of the vent pipe extends into the atomizing core sleeve,
a top end of the vent pipe is connected with the airflow baffle through the first connecting seat, and the airflow baffle is horizontally arranged in the suction nozzle;
at least one third through hole is formed in the airflow baffle in a circumferential direction; and
the air inlet hole, the vent pipe, and the third through hole all communicate with the suction nozzle.

10. The ultrasonic electronic cigarette atomizer of claim 9 , wherein:
the bottom end of the suction nozzle is connected with a top end of the side wall of the atomizer outer pipe through an upper end cover, and a bottom end of the side wall of the atomizer outer pipe is connected with a bottom seat through a lower end cover; and
a top end of the atomizing core is in insertion connection with the upper end cover, and a bottom end of the atomizing core is in screw joint with the bottom seat.

11. The ultrasonic electronic cigarette atomizer of claim 8 , wherein at least one second through hole is further formed in the bottom surface of the tobacco tar guide cotton.

12. The ultrasonic electronic cigarette atomizer of claim 8 , wherein vent grooves are uniformly formed in a boundary area of the side wall and the bottom surface of the tobacco tar guide cotton in the circumferential direction, and the area provided with no vent groove at the bottom surface of the tobacco tar guide cotton is in contact with the atomizing piece.

13. The ultrasonic electronic cigarette atomizer of claim 8 , wherein the bottom surface of the tobacco tar guide cotton is a downward protruding circular arc surface, and the circular arc surface is in contact with a central area of the atomizing piece.

14. The ultrasonic electronic cigarette atomizer of claim 8 , wherein a tobacco tar inlet hole leading to the tobacco tar guide cotton is formed in the atomizing core outer sleeve.

15. The ultrasonic electronic cigarette atomizer of claim 8 , wherein at least one groove is formed in a position, which corresponds to the tobacco tar guide cotton, on an outer side wall of the atomizing core inner sleeve.

16. The ultrasonic electronic cigarette atomizer of claim 8 , wherein:
the ultrasonic electronic cigarette atomizing core further comprises an elastic bracket,
a step is formed on an inner side wall of the atomizing core inner sleeve,
a top end of the elastic bracket is clamped at the step, and
an other end of the elastic bracket extrudes an inner bottom surface of the tobacco tar guide cotton.
