Being different from the situation of the prior art, the application discloses an electronic atomization device and an atomizer thereof. Through the tip that is equipped with at the support towards the stock solution chamber and hide the gas groove, sealed lid elasticity closing cap hides the gas groove, hide the air tank internal packing and have the air, hydraulic pressure in the stock solution intracavity, the pressure of atmospheric pressure and sealed lid is held the power, make before the stock solution intracavity does not produce the negative pressure, hide the air in the gas groove and be sealed up by sealed lid and deposit, and when the stock solution intracavity produces the negative pressure, because hide the effect of the inside and outside differential pressure of gas groove, the closing cap that causes sealed lid in its air can be backed down, in order to supply to the stock solution intracavity, increase the atmospheric pressure in the stock solution intracavity, make the liquid of stock solution intracavity storage flow to atomizing core more smoothly, avoid too low and then arouse down the not smooth situation of liquid to take place because of taking a breath the atmospheric pressure that leads to when untimely. It can be understood that when the negative pressure in the liquid storage cavity is small, the sealing cover of the sealing cover can be not opened, and only deformation occurs.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
