In addition, in order to achieve electrical isolation and avoid short circuit, an insulating member (not shown in the figure) is interposed between the second electrode post 49 and the connecting tube 442, and the material of the insulating member includes but is not limited to silicone or rubber.

Please refer to FIGS. 5 and 6. When the electronic cigarette of the present invention is used, the external air passes through the gap, the gas regulating port 451, the air inlet 441, the communication hole 461, the inner cavity of the base 44 and the first electrode column 46 in this order. After the inner cavity enters the heating cavity 410, it becomes a hot air flow under the heating effect of the heating element 48, and then, the hot air flow enters the atomizing cavity 310 after passing through the vent hole 331, so that the filling in the atomizing cavity 310 is heated Smoke is generated, and finally the smoke mixed with external air passes through the through hole on the baffle 25 and enters the user's mouth through the smoke exit channel. The direction indicated by the arrows in FIGS. 5 and 6 is the airflow direction.

In this way, the smoking substance filled in the atomizing chamber 310 is not realized by directly heating the smoke pot 31, but the airflow entering the electronic cigarette is first heated, and then the smoking substance is heated by the heated airflow, which is effective This prevents the user from being scalded due to the excessively high temperature of the smoke pot 31, and also makes the heating of the smoking material more uniform, so that the smoke formed after heating has a better taste. At the same time, heating the gas that has not yet entered the smoke pot 31 avoids the excessive heat loss of the smoke-generating substance and reduces energy consumption.

Please refer to FIG. 5 again. In this embodiment, the space enclosed between the inner wall of the housing 10 and the outer wall of the sleeve 41 constitutes an insulating cavity 103, and the insulating cavity 103 is in communication with the air inlet hole 102 and the air regulating port 451 , So that when the user performs a suction operation, part of the outside air can enter the heating chamber 410 through the air inlet 102, the heat insulating cavity 103, and the gas adjustment port 451 in sequence. On the one hand, part of the heat of the insulating cavity 103 can preheat the gas in and out of the insulating cavity 103, so that the gas entering the heating cavity 410 already has a certain temperature, thereby reducing energy consumption; on the other hand The heat insulation cavity 103 can play a role of heat insulation and heat insulation, can weaken the heat transfer function of the sleeve 41 to the housing 10, and prevent the user from being scalded due to the high temperature of the housing 10.

The atomizer 100 provided by the present invention first heats the airflow entering the electronic cigarette, and then heats the smoking material by the heated airflow, which effectively prevents the user from being scalded due to the high temperature of the smoke pot 31 It also makes the heating of the smoking material more uniform, so that the smoke formed after heating has a better taste. At the same time, heating the gas that has not yet entered the smoking pot 31 avoids the excessive heat loss of the smoke-generating substance, reduces energy consumption, enhances the user's smoking taste, and improves the user's experience.

Since the electronic cigarette of the present invention has all the technical features of the atomizer 100, it has the same technical effects as the atomizer 100.

Taking the above-mentioned ideal embodiment according to the present invention as a revelation, through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content in the description, and its technical scope must be determined according to the scope of the claims.
