In a particular embodiment, in order to prevent a large amount of aerosol-generating substrate from escaping from the nebulising sheet 18 within the nebulising chamber 121 after it has entered the nebulising chamber 121, causing problems of water leakage from the nebulising chamber 121, or problems of dry burning of no aerosol-generating substrate within the nebulising chamber 121; the liquid level detector can specifically detect the current liquid level of the aerosol generation substrate in the atomization cavity 121 in real time, and generates a first detection signal when the current liquid level reaches a preset liquid level; generating a second detection signal when the current liquid level does not reach a preset liquid level; the controller specifically responds to the received first detection signal and controls the pressure applying assembly 13 to stop working, and controls the atomizing plate 18 to start working, so as to prevent the aerosol-generating substrate in the atomizing chamber 121 from being extruded from the atomizing plate 18 by the pressure applying assembly 13 continuously applying pressure after the liquid level of the aerosol-generating substrate in the atomizing chamber 121 exceeds a preset liquid level, thereby causing the problem of water leakage of the atomizing chamber 121; and the controller is specifically responsive to the received second detection signal and controls the operation of the pressure application assembly 13 to control the operation of the atomizing plate 18 to stop so as to prevent complete atomization of the aerosol-generating substrate in the atomizing chamber 121 and continuous operation of the atomizing plate 18 to cause dry burning.

In one embodiment, the liquid level detector may include a first probe 17, a second probe connected to the controller; wherein the first probe 17 is at least partially arranged at a preset height within the nebulization chamber 121, which preset height, as will be understood, corresponds to a preset level of aerosol-generating substrate; the metal sheet of the atomizing sheet 18 may be used as a second probe; the first probe 17 and/or the second probe generate a first detection signal, e.g. a high level signal, in particular when the aerosol-generating substrate switches the first probe 17 and the second probe on; a second detection signal, e.g. a low level signal, is generated when the first probe 17 and the second probe are not conducting.

Specifically, when the aerosol-generating substrate is brought into contact with the first probe 17 and the second probe, respectively, the aerosol-generating substrate brings the metal portion of the first probe 17 and the metal sheet of the microporous atomization sheet 18 into a close conduction state; after the aerosol-generating substrate has been completely nebulized, the metal portion of the first probe 17 and the metal sheet of the microporous nebulizing plate 18 approach an open circuit state.

During a specific atomization process, bubbles are easily formed in the atomization chamber 121, and the bubbles are attached between the first probe 17 and the atomization sheet 18; thus, even if the level of the aerosol-generating substrate has reached or even exceeded the preset level, i.e. the aerosol-generating substrate has come into contact with the first probe 17 and the atomizing plate 18, since the first probe 17 and the atomizing plate 18 are separated by the bubbles, a loop cannot be formed, and a first detection signal cannot be sent, the controller does not receive the first detection signal, the pressure applying assembly 13 applies pressure all the time, and the aerosol-generating substrate is directly caused to leak from the micropores on the metal sheet of the atomizing plate 18; in the atomization process, residual water films are possibly attached to the first probe 17 and the atomization sheet 18, so that even if the liquid level of the aerosol generating substrate is reduced below the preset liquid level, the liquid level detection body still sends a first detection signal because the first probe 17 and the atomization sheet 18 are connected through the water films, and the controller receives the first detection signal and continuously controls the pressing assembly 13 to stop working, so that the pressing assembly 13 does not pump air timely to directly cause dry burning of the atomization sheet 18. In order to solve the above problems, in the present application, a boss 121b may be further disposed on an inner side wall of the atomizing chamber 121, and at least a portion of the boss 121b is located between the first probe 17 and the second probe, so as to pierce bubbles generated in the atomizing process through the boss 121b, thereby preventing the first probe 17 and the atomizing sheet 18 from being conducted and isolated due to the bubbles, and when the current liquid level detected by the liquid level detector exceeds a preset liquid level, the air pump continues to pump air, so as to cause water leakage in the atomizing chamber 121; and the boss 121b is used for cutting off the aerosol in the atomizing cavity 121 to generate a water film remained after the substrate is atomized, so that the situation that the first probe 17 and the atomizing sheet 18 are continuously conducted due to the water film and the dry burning caused by the failure of supplying liquid in time is avoided.

Referring to fig. 6, fig. 6 is an enlarged view of a structure at B in fig. 5 according to an embodiment of the present disclosure; the angle α at the corner of the boss 121b may range from 80-100 degrees; preferably, the angle α may be 90 degrees to intercept the water film; further, the intersection position C of the boss 121b and the inner sidewall of the atomizing chamber 121 may be curved to avoid liquid accumulation at the turning point.

The position of the boss 121b can be specifically set according to the requirement of an actual preset liquid level; preferably, the boss 121b may be provided on the inner surface of the throat portion 1212 and may be located away from the straight tube portion 1211 to enable the aerosol-generating substrate within the nebulization chamber 121 to be nebulized as completely as possible, reducing residue of the aerosol-generating substrate after nebulization. In this embodiment, the height of the boss 121b in the direction parallel to the straight tube portion 1211 is not less than 2 mm.

In one embodiment, the first probe 17 may be located on the boss 121 b; the air duct 16 extending into the atomizing chamber 121 can pass through the boss 121b to be in plug-in communication with the pressure applying assembly 13.

The specific operation of the electronic atomizer 10 will be described in detail below.

Take the pressing component 13 as an air pump as an example; after the liquid storage body 14 is inserted into the free end of the air duct 16, triggering the air pump to start working and pumping air; the air in the air pump enters the liquid storage body 14 through the air duct 16, the pressure in the liquid storage body 14 is increased, and the aerosol generating substrate flows out of the liquid storage body 14 and then enters the atomizing cavity 121; the liquid level of the aerosol-generating substrate in the atomizing chamber 121 rises, the air in the atomizing chamber 121 is discharged from the exhaust passage 124, the liquid level of the aerosol-generating substrate continuously rises, and after the liquid level reaches a preset liquid level and contacts the first probe 17, the controller generates and sends a first detection signal, responds to the received first detection signal, controls the air pump to stop working, and controls the atomizing sheet 18 to start working, so as to atomize the aerosol to generate the substrate; in the atomization process, after the liquid level of the aerosol generating substrate is lower than the preset liquid level, namely the aerosol generating substrate cannot contact with the first probe 17, the controller generates and sends a second detection signal, the controller responds to the received second detection signal to control the atomization sheet 18 to stop working and control the air pump to start working so as to continuously supply air to the liquid storage body 14; and then, the following steps are repeated to realize the automatic liquid supply of the electronic atomization device 10, so that the operation is simpler.
