Specifically, an atomizing core 10 and a liquid storage space a are generally arranged in the electronic atomizing device 100, liquid such as a combined liquid matrix containing essence and perfume, a liquid medicine, a nutrient solution and the like is stored in the liquid storage space a, the atomizing core 10 is used for atomizing the liquid stored in the electronic atomizing device 100 to generate aerosol when the electronic atomizing device works, and the electronic atomizing device can be used in different fields, such as medical atomization, cosmetic atomization, leisure smoking and the like. However, the conventional atomizing core 10 mostly depends on the capillary force to supply liquid, and is easily affected by the liquid content, so that the liquid supply to the atomizing core 10 is not uniform, and the user experience is affected. For example, excessive liquid supply to the atomizing core 10 results in liquid leakage, resulting in waste and hygiene problems; or when the atomizing core 10 continuously works, the atomizing core 10 is not dried due to untimely liquid supply, so that scorched smell is easily generated and the heating body 11 is easily damaged.

In order to solve the problems of liquid leakage, dry burning, uneven liquid supply and the like of the conventional electronic atomization device 100, refer to fig. 4, and fig. 4 is a schematic structural diagram of the atomization core shown in fig. 2.

For example, if the pressure sensor 12 detects that the pressure value inside the micropores is greater than the external atmospheric pressure value, indicating that there is a problem of excessive liquid supply, the electronic atomization device 100 increases the output W to the atomization layer 112, and/or reduces the liquid supply to the liquid absorption layer 111, so as to prevent the excessive liquid supply from causing insufficient atomization to the liquid in the atomization layer 112, and the liquid leaks from the heating element 11 or is inhaled into the body of the user, which may affect the health and hygiene of the electronic atomization device 100. If the pressure sensor 12 detects that the pressure value in the micropores is smaller than the preset negative pressure value, indicating that there is a problem of insufficient liquid supply, the electronic atomization device 100 reduces or interrupts the output power W to the atomization layer 112, and/or increases the liquid supply to the liquid absorption layer 111, so as to prevent the insufficient liquid supply from causing dry burning of the atomization layer 112, resulting in the generated aerosol having scorched smell, and possibly causing damage to the heating element 11 when the dry burning is serious. If the pressure sensor 12 detects that the pressure value in the pores is in the normal range, which indicates that the liquid supply is normal, the electronic atomization device 100 recovers the standard output power W for the atomization layer 112 and/or recovers the normal liquid supply for the liquid absorbent layer 111.

For example, the liquid absorbent layer 111 is a ceramic layer having irregular micropores, or the liquid absorbent layer 111 is a dense ceramic layer having regular micropores; or the liquid absorbent layer 111 is a dense glass layer having regular micropores.

The atomizing layer 112 can heat the liquid on the atomizing liquid absorbing layer 111 under the power-on condition, and the atomizing layer 112 includes a heating wire, a heating net or a heating film.

The pressure sensor 12 may also be a hydraulic sensor, and the liquid in the micro-hole contacts the hydraulic sensor through the sensing channel 13. When the pressure sensor 12 is a hydraulic sensor, the aperture and length of the sensing channel 13 are not limited, as long as the liquid in the micropores can directly contact the hydraulic sensor through the sensing channel 13, and the liquid leakage from the sensing channel 13 is avoided.
