Abstract

An atomizer with an upgraded air passage structure includes a housing, a heating piece and an air passage disposed in the housing; the heating piece is disposed inside an atomizer chamber, a blocking piece is disposed in the air passage and configured for blocking an airflow; the blocking piece divides the air passage into an air inlet area and an air outlet area; the air outlet area and the air inlet area are both disposed at a different axial position with the atomizing chamber; the atomizing chamber is respectively communicated with the air inlet area and the air outlet area; the airflow in the air inlet area flows downwards to the atomizing chamber, then flows upwards to the air outlet area. An electronic cigarette having the aforementioned atomizer is further disclosed.

First claim

What is claimed is:

1. An atomizer with an upgraded air passage structure comprising:
a housing;
a heating piece; and
an air passage disposed in the housing; the heating piece is disposed inside an atomizer chamber, a blocking piece is disposed in the air passage and configured for blocking an airflow; the blocking piece divides the air passage into an air inlet area and an air outlet area; the air outlet area and the air inlet area are both disposed at an axial position that is different with the atomizing chamber; the atomizing chamber is respectively communicated with the air inlet area and the air outlet area; the air in the air inlet area flows downwards to the atomizing chamber, then flows upwards to the air outlet area;
wherein a first air inlet is disposed on the housing; the air inlet area comprises a second air inlet communicated with the atomizing chamber that is at a lower axial position, the second air inlet and the first air inlet are staggered along a horizontal direction;
wherein the air outlet area has a first air outlet communicated with the atomizing chamber: the first air outlet and the second air inlet are disposed at two sides of the atomizing chamber.

2. The atomizer according to claim 1 , wherein the first air inlet is disposed at an axial position above the blocking piece.

3. The atomizer according to claim 2 , wherein the first air inlet is disposed on a side wall of the housing, communicated with the air inlet area via an air pipe inside the side wall of the housing.

4. The atomizer according to claim 1 , wherein a top of the housing has a second air outlet, the second air outlet and the first air outlet are staggered along a horizontal direction.

5. The atomizer according to claim 4 , wherein a stagger angle between the second air outlet and the first air outlet is 90 degree; and a stagger angle between the second air inlet and the first air inlet is 90 degree.

6. The atomizer according to claim 1 , wherein the blocking piece comprises a silicone seat and a base; the air inlet area and the air outlet area are defined by the silicone seat matching with the base and a supporter for fixing the heating piece; where the atomizing chamber is defined by the base and the supporter for fixing the heating piece; a bottom of the base has a recessed shape, used for accumulating a certain amount of the tobacco liquid.

7. The atomizer according to claim 6 , wherein a protuberant separating bar is formed on a surface of the blocking piece; the separating bar is integrally manufactured with the silicone seat; the separating bar defines the air inlet area and the air outlet area by dividing a space between the housing and the liquid storage cup into two side areas.

8. The atomizer according to claim 1 , wherein a center of the housing has a liquid storage cup, a bottom end of the liquid storage cup has an opening; the air passage is defined by areas surrounding and below the liquid storage cup.

9. An electronic cigarette comprising:
an atomizer with an upgraded air pipe structure comprising:
a housing;
a heating piece; and
an air passage disposed in the housing; the heating piece is disposed inside an atomizer chamber, a blocking piece is disposed in the air passage and configured for blocking an airflow; the blocking piece divides the air passage into an air inlet area and an air outlet area; the air outlet area and the air inlet area are both disposed at an axial position that is different with the atomizing chamber; the atomizing chamber is respectively communicated with the air inlet area and the air outlet area; the air in the air inlet area flows downwards to the atomizing chamber, then flows upwards to the air outlet area; and
a power supply configured for supplying power to the atomizer;
wherein a first air inlet is disposed on the housing; the air inlet area comprises a second air inlet communicated with the atomizing chamber that is at a lower axial position, the second air inlet and the first air inlet are staggered along a horizontal direction;
wherein the air outlet area has a first air outlet communicated with the atomizing chamber: the first air outlet and the second air inlet are disposed at two sides of the atomizing chamber.

10. The electronic cigarette according to claim 9 , wherein the first air inlet is disposed at an axial position above the blocking piece.

11. The electronic cigarette according to claim 10 , wherein the first air inlet is disposed on a side wall of the housing, communicated with the air inlet area via an air pipe inside the side wall of the housing.

12. The electronic cigarette according to claim 9 , wherein a top of the housing has a second air outlet, the second air outlet and the first air outlet are staggered along a horizontal direction.

13. The electronic cigarette according to claim 12 , wherein a stagger angle between the second air outlet and the first air outlet is 90 degree; and a stagger angle between the second air inlet and the first air inlet is 90 degree.

14. The electronic cigarette according to claim 9 , wherein the blocking piece comprises a silicone seat and a base; the air inlet area and the air outlet area are defined by the silicone seat matching with the base and a supporter for fixing the heating piece; where the atomizing chamber is defined by the base and the supporter for fixing the heating piece; a bottom of the base has a recessed shape, used for accumulating a certain amount of the tobacco liquid.

15. The electronic cigarette according to claim 14 , wherein a protuberant separating bar is formed on a surface of the blocking piece; the separating bar is integrally manufactured with the silicon silicone seat; the separating bar defines the air inlet area and the air outlet area by dividing a space between the housing and the liquid storage cup into two side areas.

16. The electronic cigarette according to claim 9 , wherein a center of the housing has a liquid storage cup, a bottom end of the liquid storage cup has an opening; the air passage is defined by areas surrounding and below the liquid storage cup.
