However, as the atomization proceeds, the aerosol substrate in the receiving cavity 111 is gradually consumed, which may eventually lead to a negative pressure in the receiving cavity 111, affecting the independent transfer of the aerosol substrate to the porous body 121, resulting in dry burning of the atomizing core 12 or a reduction in the atomization amount, etc. In order to balance the air pressure in the accommodating cavity 111 and ensure the stable atomization amount of the atomizing core 12, the atomizer 1 is further provided with an air guide channel D2, the air guide channel D2 can be communicated with the accommodating cavity 111 and the atomizing cavity, and when the air pressure difference between the air guide channel D1 and the accommodating cavity 111 reaches a preset degree, air enters the accommodating cavity 111 to supplement the air pressure in the accommodating cavity 111.

The elastic cover sheet 141 is configured to be deformable to open the air outlet 172 of the air hole 17, and when the pressure difference between the air guide passage D2 and the receiving chamber 111 does not reach a predetermined level, the elastic cover sheet 141 covers the air outlet 172 for preventing the aerosol substrate in the receiving chamber 111 from entering the air hole 17 to prevent the aerosol substrate from leaking. When the air pressure difference between the air guide channel D2 and the accommodating cavity 111 reaches a preset degree, under the action of the pressure difference, the air in the air guide channel D2 pushes the elastic cover sheet 141 open, and enters the accommodating cavity 111 through the air outlet 172, until the air pressure difference between the air guide channel D2 and the accommodating cavity 111 is reduced to the preset degree, and the elastic cover sheet 141 closes the air outlet 172 again under the action of the elastic restoring force.
