Specifically, the first accommodating cavity 1111 is further provided with a sensing chamber 141, the sensing chamber 141 is separated from the first accommodating cavity 1111, the sensor 14 is accommodated in the sensing chamber 141, the sensing chamber 141 is communicated with the atomizing assembly 20 through a third air inlet 142, and at least part of the third air inlet 142 is located on the second partition 133. The controller 15 may be secured to the bracket 13 by means of a snap 134 fit connection.

When the user uses the electronic atomizer 100, an air flow is generated in the air intake assembly 10, and the air in the sensing chamber 141 flows into the atomizing assembly 20 through the third air intake holes 142, so that the sensor 14 senses the negative pressure formed in the sensing chamber 141 and transmits a signal to the controller 15.

The air inlet assembly 10 further includes a sensor silicone sleeve 16, referring to fig. 3, which is sleeved on the outer periphery of the sensor 14 to prevent the sensor 14 from being damaged due to hard contact between the sensor 14 and the sensing chamber 141.

In one embodiment, referring to fig. 3, the air inlet assembly 10 further includes a magnet 17 and a spring electrode 18, and the magnet 17 and the spring electrode are disposed on the second partition 133. The magnet 17 may cooperate with a magnetic substance (not shown) in the atomizing assembly 20, so as to fixedly connect the atomizing assembly 20 and the second partition 133 to each other, and also facilitate the user to separate the atomizing assembly 20 from the air inlet assembly 10; the spring electrodes are used to connect the positive and negative electrodes in the atomizing assembly 20, and when the controller 15 controls the electronic atomizer 100 to start operating, the spring electrodes can supply power to the atomizing assembly 20.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
