Abstract

Disclosed is an ultrasonic electronic cigarette atomizer. An atomizer shell, an atomization piece and a liquid guide structure are arranged in the atomizer. The liquid guide structure communicates with a liquid storage cavity in the atomizer shell. A heating body is further arranged in the atomizer shell. Both of the atomization piece and the heating body are in contact with the liquid guide structure, and both of the heating body and an atomization surface of the atomization piece communicate with an airflow passage, and a positive electrode and a negative electrode of the heating body are respectively connected with one end and the other end of a power supply. The heating body can not only quickly heat the tobacco tar to approach to its atomization temperature, but also can transfer a part of heat to the atomization piece, so that the atomization piece atomizes the tobacco tar quickly, shortening the atomization time.

First claim

The invention claimed is:

1. An ultrasonic electronic cigarette atomizer, comprising an atomizer shell, wherein:
an ultrasonic atomization piece and a liquid guide structure are arranged in the atomizer shell, the liquid guide structure communicates with a liquid storage cavity in the atomizer shell,
a heating body is further arranged in the atomizer shell, both of the ultrasonic atomization piece and the heating body are in contact with the liquid guide structure, both of the heating body and an atomization surface of the ultrasonic atomization piece communicate with an airflow passage, and
a positive electrode and a negative electrode of the heating body are respectively connected with one end and another end of a power supply.

2. The ultrasonic electronic cigarette atomizer of claim 1 , wherein the liquid guide structure comprises atomization cotton in contact with one side surface of the ultrasonic atomization piece, both of the ultrasonic atomization piece and the atomization cotton being fixed on an atomization core bracket, the atomization cotton being clamped between the heating body and the ultrasonic atomization piece.

3. The ultrasonic electronic cigarette atomizer of claim 2 , wherein one end of a side wall of the atomizer shell is connected with a suction nozzle, a washer and a pressing ring, which are detachably connected with each other, and are arranged in the atomization core bracket, and the ultrasonic atomization piece is arranged to be parallel to a length direction of an electronic cigarette, the ultrasonic atomization piece is fixed in the washer, one end of the atomization cotton is arranged between the washer and the pressing ring, and another end of the atomization cotton extends into a tobacco tar bottle, a projection which abuts against the heating body is arranged on the pressing ring, a first hollow cavity which communicates with the suction nozzle is formed between the pressing ring and the atomization cotton, an air pass groove which communicates with an outside and is parallel to the length direction of the electronic cigarette is formed in the side wall, away from the ultrasonic atomization piece, of the pressing ring, an air pass hole is formed in a position in the pressing ring, the position in the pressing ring corresponds to one end, away from the suction nozzle, of the ultrasonic atomization piece, and the air pass hole communicates the air pass groove and the first hollow cavity.

4. The ultrasonic electronic cigarette atomizer of claim 2 , wherein a depressed region is formed in an outer side wall of the atomization core bracket.

5. The ultrasonic electronic cigarette atomizer of claim 3 , wherein a second hollow cavity is formed between the ultrasonic atomization piece and the washer.

6. The ultrasonic electronic cigarette atomizer of claim 3 , wherein a tobacco tar bottle placing cavity which places the tobacco tar bottle is formed in one end, away from the suction nozzle, of the atomization core bracket.

7. The ultrasonic electronic cigarette atomizer of claim 6 , wherein the heating body is in contact with a first position, aligned to a central area of the ultrasonic atomization piece, of the atomization cotton, or the heating body is in contact with the atomization cotton at a second position, which is closer to a tobacco tar cup than the first position.

8. The ultrasonic electronic cigarette atomizer of claim 2 , wherein the heating body is an electric heating piece or a disc-shaped electric heating wire.

9. The ultrasonic electronic cigarette atomizer of claim 2 , wherein a wiring groove is formed in the atomization core bracket.

10. The ultrasonic electronic cigarette atomizer of claim 3 , wherein a sealing pad is arranged in the suction nozzle.
